+2013-01-14  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclInt.decls: Put back Tcl_[GS]etStartupScript in
+	internal stub table, so extensions using this, compiled
+	against 8.5 headers still run in Tcl 8.6.
+
+2013-01-13  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>
+	* doc/fileevent.n: Clarify readable fileevent "false positives" in
+	the case of multibyte encodings/transforms [Bug 3436609].
+
+2013-01-13  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclIntDecls.h: If TCL_NO_DEPRECATED is defined, make
+	sure that TIP #139 functions all are taken from the public stub
+	table, even if the inclusion is through tclInt.h.
+
+2013-01-12  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclInt.decls: Put back TclBackgroundException in
+	internal stub table, so extensions using this, compiled
+	against 8.5 headers still run in Tcl 8.6.
+
+2013-01-09  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* library/http/http.tcl: [Bug 3599395]: http assumes status line
+	is a proper tcl list.
+
+2013-01-08  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* win/tclWinFile.c: [Bug 3092089]: [file normalize] can remove path
+	components.	[Bug 3587096] win vista/7: "can't find init.tcl" when
+	called via junction without folder list access.
+
+2013-01-07  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclOOStubLib.c: Restrict the stub library to only use
+	* generic/tclTomMathStubLib.c: Tcl_PkgRequireEx, Tcl_ResetResult
+	and Tcl_AppendResult, not any other function. This puts least
+	restrictions on eventual Tcl 9 stubs re-organization, and it
+	works on the widest range of Tcl versions.
+
+2013-01-06  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* library/http/http.tcl: Don't depend on Spencer-specific regexp
+	* tests/env.test: syntax (/u and /U) any more in unrelated places.
+	* tests/exec.test:
+	Bump http package to 2.8.6.
+
+2013-01-04  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclEnsemble.c (CompileBasicNArgCommand): Added very simple
+	compiler (which just compiles to a normal invoke of the implementation
+	command) for many ensemble subcommands where we can prove that there
+	is no way for scripts to detect the difference even through error
+	handling or [info level]/[info frame]. This improves the code produced
+	from some ensembles (e.g., [info], [string]) to the point where the
+	ensemble is now not normally seen at the bytecode level at all.
+
+2013-01-04  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclInt.h:      Insure that PURIFY builds cannot exploit the
+	* generic/tclExecute.c:  Tcl stack to hide mem defects.
+
+2013-01-03  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/fconfigure.n, doc/CrtChannel.3: Updated to reflect the fact that
+	the minimum buffer size is one byte, not ten. Identified by Schelte
+	Bron on the Tcler's Chat.
+
+	* generic/tclExecute.c (TEBCresume:INST_INVOKE_REPLACE):
+	* generic/tclEnsemble.c (TclCompileEnsemble): Added new mechanism to
+	allow for more efficient dispatch of non-bytecode-compiled subcommands
+	of bytecode-compiled ensembles. This can provide substantial speed
+	benefits in some cases.
+
+2013-01-02  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclEnsemble.c:  Remove stray calls to Tcl_Alloc and friends:
+	* generic/tclExecute.c:   the core should only use ckalloc to allow
+	* generic/tclIORTrans.c:  MEM_DEBUG to work properly.
+	* generic/tclTomMathInterface.c:
+
+2012-12-31  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/string.n: Noted the obsolescence of the 'bytelength',
+	'wordstart' and 'wordend' subcommands, and moved them to later in the
+	file.
+
+2012-12-27  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclListObj.c: [Bug 3598580]: Tcl_ListObjReplace may release
+	deleted elements too early.
+
+2012-12-22  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>
+
+	* generic/tclUtil.c: Stop leaking allocated space when objifying a
+	zero-length DString. [Bug 3598150] spotted by afredd.
+
+2012-12-21  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* unix/dltest/pkgb.c:  Inline compat Tcl_GetDefaultEncodingDir.
+	* generic/tclStubLib.c: Eliminate unnecessary static HasStubSupport()
+	and isDigit() functions, just do the same inline.
+
+2012-12-18  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmdsSZ.c (TclSubstCompile): Improved the sequence of
+	instructions issued for [subst] when dealing with simple variable
+	references.
+
+2012-12-14  Don Porter  <dgp@users.sourceforge.net>
+
+	*** 8.6.0 TAGGED FOR RELEASE ***
+
+	* changes: updates for 8.6.0
+
+2012-12-13  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclZlib.c:	Repair same issue with misusing the
+	* tests/zlib.test:	'fire and forget' nature of Tcl_ObjSetVar2
+	in the new TIP 400 implementation.
+
+2012-12-13  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCmdAH.c:	(CatchObjCmdCallback): do not decrRefCount
+	* tests/cmdAH.test:	the newValuePtr sent to Tcl_ObjSetVar2:
+	TOSV2 is 'fire and forget', it decrs on its own.
+	Fix for [Bug 3595576], found by andrewsh.
+
+2012-12-13  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tcl.h: Fix Tcl_DecrRefCount macro such that it doesn't
+	access its objPtr parameter twice any more.
+
+2012-12-11  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tcl.h:	Bump version number to 8.6.0.

+
+2012-12-10  Donal K. Fellows  <dkf@users.sf.net>
+
+	* tools/tcltk-man2html.tcl (plus-pkgs): Increased robustness of
+	version number detection code to deal with packages whose names are
+	prefixes of other packages.
+	* unix/Makefile.in (dist): Added pkgs/package.list.txt to distribution
+	builds to ensure that 'make html' will work better.
+
+2012-12-09  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>
+
+	* tests/chan.test: Clean up unwanted eofchar side-effect of chan-4.6
+	leading to a spurious "'" at end of chan.test under certain conditions
+	(see [Bug 3389289] and [Bug 3389251]).
+
+	* doc/expr.n: [Bug 3594188]: Clarifications about commas.
+
+2012-12-08  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>
+
+	* generic/tclIO.c: Fix busyloop at exit under TCL_FINALIZE_ON_EXIT
+	when there are unflushed nonblocking channels.  Thanks Miguel for
+	spotting.
+
+2012-12-07  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* unix/dltest/pkgb.c:  Turn pkgb.so into a Tcl9 interoperability test
+        library: Whatever Tcl9 looks like, loading pkgb.so in Tcl 9 should
+        either result in an error-message, either succeed, but never crash.
+
+2012-11-28  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclZlib.c (ZlibStreamSubcmd): [Bug 3590483]: Use a mechanism
+	for complex option resolution that has fewer problems with more
+	finicky compilers.
+
+2012-11-26  Reinhard Max  <max@suse.de>
+
+	* unix/tclUnixSock.c: Factor out creation of the -sockname and
+	-peername lists from TcpGetOptionProc() to TcpHostPortList().  Make it
+	robust against implementations of getnameinfo() that error out if
+	reverse mapping fails instead of falling back to the numeric
+	representation.
+
+2012-11-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclBinary.c (BinaryDecode64): [Bug 3033307]: Corrected
+	handling of trailing whitespace when decoding base64. Thanks to Anton
+	Kovalenko for reporting, and Andy Goth for the fix and tests.
+
+2012-11-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclExecute.c (INST_STR_RANGE_IMM): [Bug 3588366]: Corrected
+	implementation of bounds restriction for end-indexed compiled [string
+	range]. Thanks to Emiliano Gavilan for diagnosis and fix.
+
+2012-11-15  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	IMPLEMENTATION OF TIP#416
+
+	New Options for 'load': -global and -lazy
+
+	* generic/tcl.h:
+	* generic/tclLoad.c
+	* unix/tclLoadDl.c
+	* unix/tclLoadDyld.c
+	* tests/load.test
+	* doc/Load.3
+	* doc/load.n
+
+2012-11-14  Donal K. Fellows  <dkf@users.sf.net>
+
+	* unix/tclUnixFCmd.c (TclUnixOpenTemporaryFile): [Bug 2933003]: Factor
+	out all the code to do temporary file creation so that it is possible
+	to make it correct in one place. Allow overriding of the back-stop
+	default temporary file location at compile time by setting the
+	TCL_TEMPORARY_FILE_DIRECTORY #def to a string containing the directory
+	name (defaults to "/tmp" as that is the most common default).
+
+2012-11-13  Joe Mistachkin  <joe@mistachkin.com>
+
+	* win/tclWinInit.c: also search for the library directory (init.tcl,
+	encodings, etc) relative to the build directory associated with the
+	source checkout.
+
+2012-11-10  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c:   re-enable bcc-tailcall, after fixing an
+	* generic/tclExecute.c: infinite loop in the TCL_COMPILE_DEBUG mode
+
+
+2012-11-07  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/tzdata/Africa/Casablanca:
+	* library/tzdata/America/Araguaina:
+	* library/tzdata/America/Bahia:
+	* library/tzdata/America/Havana:
+	* library/tzdata/Asia/Amman:
+	* library/tzdata/Asia/Gaza:
+	* library/tzdata/Asia/Hebron:
+	* library/tzdata/Asia/Jerusalem:
+	* library/tzdata/Pacific/Apia:
+	* library/tzdata/Pacific/Fakaofo:
+	* library/tzdata/Pacific/Fiji:		Import tzdata2012i.
+
+2012-11-06  Donal K. Fellows  <dkf@users.sf.net>
+
+	* library/http/http.tcl (http::Finish): [Bug 3581754]: Ensure that
+	callbacks are done at most once to prevent problems with timeouts on a
+	keep-alive connection (combined with reentrant http package use)
+	causing excessive stack growth. Not a fix for the underlying problem,
+	but ensures that pain will be mostly kept away from users.
+	Bump http package to 2.8.5.
+
+2012-11-05  Donal K. Fellows  <dkf@users.sf.net>
+
+	Added bytecode compilation of many Tcl commands. Some of these are
+	total compilations and some are only partial (i.e., only compile in
+	some cases). The (sub-)commands affected are:
+	* array: exists, set, unset
+	* dict: create, exists, merge
+	* format: (simple cases only)
+	* info: commands, coroutine, level, object
+	* info object: class, isa object, namespace
+	* namespace: current, code, qualifiers, tail, which
+	* regsub: (only cases convertable to simple [string map])
+	* self: (only no-argument and [self object] cases)
+	* string: first, last, map, range
+	* tailcall:
+	* yield:
+
+	[This was work originally done on the 'dkf-compile-misc-info' branch.]
+
+2012-11-05  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	IMPLEMENTATION OF TIP#413
+
+	Align the [string trim] and [string is space] commands, such that
+	[string trim] by default trims all characters for which [string is
+	space] returns 1, augmented with the NUL character.
+
+	* generic/tclUtf.c: Add NEL, BOM and two more characters to [string is
+	space]
+	* generic/tclCmdMZ.c: Modify [string trim] for Unicode modifications.
+	* generic/regc_locale.c: Regexp engine must match [string is space]
+	* doc/string.n
+	* tests/string.test
+	***POTENTIAL INCOMPATIBILITY***
+	Code that relied on characters not previously trimmed being not
+	removed will notice a difference; it is believed that this is rare,
+	but a workaround to get the behavior in Tcl 8.5 is to use " \t\n\r" as
+	an explicit trim set.
+
+2012-10-31  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* win/Makefile.in:   Dde version number to 1.4.0, ready for Tcl 8.6.0rc1
+	* win/makefile.vc
+	* win/tclWinDde.c
+	* library/dde/pkgIndex.tcl
+	* tests/winDde.test
+
+2012-10-24  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileDictUnsetCmd): Added compilation of
+	the [dict unset] command (for scalar var in LVT only).
+
+2012-10-23  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclInt.h:       Add "flags" parameter from Tcl_LoadFile to
+	* generic/tclIOUtil.c:    to various internal functions, so these
+	* generic/tclLoadNone.c:  flags are available through the whole
+	* unix/tclLoad*.c:        filesystem for (future) internal use.
+	* win/tclWinLoad.c:
+
+2012-10-17  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c (TclNRCoroutineObjCmd): insure that numlevels
+	are properly set, fix bug discovered by dkf and reported at
+	http://code.activestate.com/lists/tcl-core/12213/
+
+2012-10-16  Donal K. Fellows  <dkf@users.sf.net>
+
+	IMPLEMENTATION OF TIP#405
+
+	New commands for applying a transformation to the elements of a list
+	to produce another list (the [lmap] command) and to the mappings of a
+	dictionary to produce another dictionary (the [dict map] command). In
+	both cases, a [continue] will cause the skipping of an element/pair,
+	and a [break] will terminate the construction early and successfully.
+
+	* generic/tclCmdAH.c (Tcl_LmapObjCmd, TclNRLmapCmd): Implementation of
+	the new [lmap] command, based on (and sharing much of) [foreach].
+	* generic/tclDictObj.c (DictMapNRCmd): Implementation of the new [dict
+	map] subcommand, based on (and sharing much of) [dict for].
+	* generic/tclCompCmds.c (TclCompileLmapCmd, TclCompileDictMapCmd):
+	Compilation engines for [lmap] and [dict map].
+
+	IMPLEMENTATION OF TIP#400
+
+	* generic/tclZlib.c: Allow the specification of a compression
+	dictionary (a binary blob used to seed the compression engine) in both
+	streams and channel transformations. Also some reorganization to allow
+	for getting gzip header dictionaries and controlling buffering levels
+	in channel transformations (allowing a trade-off between formal
+	correctness and speed).
+	(Tcl_ZlibStreamSetCompressionDictionary): New C API to allow setting
+	the compression dictionary without using a Tcl script.
+
+2012-10-14  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclDictObj.c: [Bug 3576509]: ::tcl::Bgerror crashes with
+	* generic/tclEvent.c:    invalid arguments. Better fix, which helps
+	for all Tcl_DictObjGet() calls in Tcl's source code.
+
+2012-10-13  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclEvent.c: [Bug 3576509]: tcl::Bgerror crashes with invalid
+	arguments
+
+2012-10-06  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* win/Makefile.in: [Bug 2459774]: tcl/win/Makefile.in not compatible
+	with msys 0.8.
+
+2012-10-03  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclIO.c:	When checking for std channels being closed,
+	compare the channel state, not the channel itself so that stacked
+	channels do not cause trouble.
+
+2012-09-26  Reinhard Max  <max@suse.de>
+
+	* generic/tclIOSock.c (TclCreateSocketAddress): Work around a bug in
+	getaddrinfo() on OSX that caused name resolution to fail for [socket
+	-server foo -myaddr localhost 0].
+
+2012-09-20  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* win/configure.in: New import libraries for zlib 1.2.7, usable for
+	* win/configure:    all win32/win64 compilers
+	* compat/zlib/win32/zdll.lib:
+	* compat/zlib/win64/zdll.lib:
+
+	* win/tclWinDde.c: [FRQ 3527238]: Full unicode support for dde. Dde
+	version is now 1.4.0b2.
+	***POTENTIAL INCOMPATIBILITY***
+
+2012-09-19  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tcl.h:  Make Tcl_Interp a fully opaque structure if
+	TCL_NO_DEPRECATED is set (TIP 330 and 336).
+	* win/nmakehlp.c: Let "nmakehlp -V" start searching digits after the
+	found match (suggested by Harald Oehlmann).
+
+2012-09-07  Harald Oehlmann  <oehhar@users.sf.net>
+
+	*** 8.6b3 TAGGED FOR RELEASE ***
+
+	IMPLEMENTATION OF TIP#404.
+
+	* library/msgcat/msgcat.tcl:	[FRQ 3544988]: New commands [mcflset]
+	* library/msgcat/pkgIndex.tcl:	and [mcflmset] to set mc entries with
+	* unix/Makefile.in:		implicit message file locale.
+	* win/Makefile.in:		Bump to 1.5.0.
+
+2012-08-25  Donal K. Fellows  <dkf@users.sf.net>
+
+	* library/msgs/uk.msg: [Bug 3561330]: Use the correct full name of
+	March in Ukrainian. Thanks to Mikhail Teterin for reporting.
+
+2012-08-23  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclBinary.c: [Bug 3496014]: Unecessary memset() in
+	Tcl_SetByteArrayObj().
+
+2012-08-20  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclPathObj.c:	[Bug 3559678]: Fix bad filename normalization
+	when the last component is the empty string.
+
+2012-08-20  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* win/tclWinPort.h:  Remove wrapper macro for ntohs(): unnecessary,
+	because it doesn't require an initialized winsock_2 library. See:
+	<http://msdn.microsoft.com/en-us/library/windows/desktop/ms740075%28v=vs.85%29.aspx>
+	* win/tclWinSock.c:
+	* generic/tclStubInit.c:
+
+2012-08-17  Jan Nijtmans  <nijtmans@users.sf.net>

+	partial version numbers.
+
+2012-08-15  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* win/buildall.vc.bat: Only build the threaded builds by default

+	'declared but never defined' compiler warnings.
+
+2012-08-13  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* compat/zlib/win64/zlib1.dll:  Add 64-bit build of zlib1.dll, and use
+	* compat/zlib/win64/zdll.lib:   it for the dynamic mingw-w64 build.
+	* win/Makefile.in:
+	* win/configure.in:
+	* win/configure:
+
+2012-08-09  Reinhard Max  <max@suse.de>

+	* tests/http.test: Fix http-3.29 for machines without IPv6 support.
+
+2010-08-08  Stuart Cassoff  <stwo@users.sourceforge.net>

+
+2012-06-06  Jan Nijtmans  <nijtmans@users.sf.net>

+2012-05-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclOOBasic.c (TclOO_Class_Constructor): [Bug 2023112]: Cut

+
+2012-05-17  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): [Bug 3106532]: Corrected

+	***POTENTIAL INCOMPATIBILITY***
+	Uses of [switch -regexp -indexvar] that previously compensated for the
+	wrong offsets (by subtracting 1 from the end indices) now do not need

+
+	* library/safe.tcl (safe::InterpInit): Ensure that the module path is

+	(safe::AliasGlob): [Bug 2964715]: More extensive handling of what
+	globbing is required to support package loading.
+
+	* doc/expr.n: [Bug 3525462]: Corrected statement about what happens

+2012-05-16  Donal K. Fellows  <dkf@users.sf.net>

+
+	* generic/tclIORChan.c: [Bug 3522560]: Fixed the crash, enabled the
+	test case. Modified [chan postevent] to properly inject the event(s)
+	into the owner thread's event queue for execution in the correct
+	context. Renamed the ForwardOpTo...Thread() function to match with our
+	terminology.
+
+	* tests/ioCmd.test: [Bug 3522560]: Added a test which crashes the core
+	if it were not disabled as knownBug. For a reflected channel
+	transfered to a different thread the [chan postevent] run in the
+	handler thread tries to execute the owner threads's fileevent scripts
+	by itself, wrongly reaching across thread boundaries.

+
+2012-03-27  Donal K. Fellows  <dkf@users.sf.net>
+
+	IMPLEMENTATION OF TIP#397.
+
+	* generic/tclOO.c (Tcl_CopyObjectInstance): [Bug 3474460]: Make the
+	target object name optional when copying classes. [RFE 3485060]: Add
+	callback method ("<cloned>") so that scripted control over copying is
+	easier.
+	***POTENTIAL INCOMPATIBILITY***
+	If you'd previously been using the "<cloned>" method name, this now
+	has a standard semantics and call interface. Only a problem if you are
+	also using [oo::copy].
+
+2012-03-26  Donal K. Fellows  <dkf@users.sf.net>
+
+	IMPLEMENTATION OF TIP#380.
+
+	* doc/define.n, doc/object.n, generic/tclOO.c, generic/tclOOBasic.c:
+	* generic/tclOOCall.c, generic/tclOODefineCmds.c, generic/tclOOInt.h:
+	* tests/oo.test: Switch definitions of lists of things in objects and
+	classes to a slot-based approach, which gives a lot more flexibility
+	and programmability at the script-level. Introduce new [::oo::Slot]
+	class which is the implementation of these things.
+
+	***POTENTIAL INCOMPATIBILITY***
+	The unknown method handler now may be asked to deal with the case
+	where no method name is provided at all. The default implementation
+	generates a compatible error message, and any override that forces the
+	presence of a first argument (i.e., a method name) will continue to
+	function as at present as well, so this is a pretty small change.
+
+	* generic/tclOOBasic.c (TclOO_Object_Destroy): Made it easier to do a
+	tailcall inside a normally-invoked destructor; prevented leakage out
+	to calling command.

+	* win/tclWinError.c:          They were an attempt to make the cygwin
+	                              port compile again, but since cygwin is
+	                              based on unix this serves no purpose any
+	                              more.
+	* win/tclWinSerial.c:         Use EAGAIN in stead of EWOULDBLOCK,

+
+2011-09-28  Jan Nijtmans  <nijtmans@users.sf.net>

+2011-09-26  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCmdAH.c (TclMakeFileCommandSafe): [Bug 3211758]: Also

+
+2011-09-23  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclIORTrans.c: More revisions to get finalization of
+	ReflectedTransforms correct, including adopting a "dead" field as was
+	done in tclIORChan.c.
+
+	* tests/thread.test:	Stop using the deprecated thread management
+	commands of the tcltest package.  The test suite ought to provide

+
+2011-09-22  Don Porter  <dgp@users.sourceforge.net>
+

+
+2011-09-21  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>

+2011-09-21  Andreas Kupries  <andreask@activestate.com>
+

+
+2011-09-20  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclIORChan.c: Re-using the "interp" field to signal a dead

+	testing for "the right interp". Added a new field "dead" to perform
+	the dead channel signalling task so the corrupted logic is avoided.
+
+	* generic/tclIORTrans.c: Revised ReflectClose() and
+	FreeReflectedTransform() so that we stop leaking ReflectedTransforms,
+	yet free all Tcl_Obj values in the same thread that alloced them.
+
+2011-09-19  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/ioTrans.test:	Conversion from [testthread] to Thread package
+	stops most memory leaks.
+
+	* tests/thread.test:	Plug most memory leaks in thread.test.
+	Constrain the rest to be skipped during `make valgrind'.  Tests using
+	the [testthread cancel] testing command are leaky.  Corrections wait
+	for either addition of [thread::cancel] to the Thread package, or
+	improvements to the [testthread] testing command to make leak-free
+	versions of these tests possible.
+

+
+	* generic/tclCompile.c (TclFixupForwardJump): Tracked down and fixed

+
+2011-05-11  Reinhard Max  <max@suse.de>
+

+2011-05-10  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclInt.h:     New internal routines TclScanElement() and

+2011-05-07  Donal K. Fellows  <dkf@users.sf.net>

+
+2011-05-05  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclListObj.c:	Stop generating string rep of dict when

+
+2011-05-02  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c:	Revised TclFindElement() interface. The final
+	* generic/tclDictObj.c:	argument had been bracePtr, the address of a
+	* generic/tclListObj.c:	boolean var, where the caller can be told
+	* generic/tclParse.c:	whether or not the parsed list element was
+	* generic/tclUtil.c:	enclosed in braces.  In practice, no callers
+	really care about that.  What the callers really want to know is
+	whether the list element value exists as a literal substring of the
+	string being parsed, or whether a call to TclCopyAndCollpase() is
+	needed to produce the list element value.  Now the final argument is
+	changed to do what callers actually need. This is a better fit for the
+	calls in tclParse.c, where now a good deal of post-processing checking
+	for "naked backslashes" is no longer necessary.
+	***POTENTIAL INCOMPATIBILITY***
+	For any callers calling in via the internal stubs table who really do
+	use the final argument explicitly to check for the enclosing brace
+	scenario.  Simply looking for the braces where they must be is the
+	revision available to those callers, and it will backport cleanly.
+
+	* tests/parse.test:	Tests for expanded literals quoting detection.
+
+	* generic/tclCompCmdsSZ.c:	New TclFindElement() is also a better
+	fit for the [switch] compiler.
+
+	* generic/tclInt.h:	Replace TclCountSpaceRuns() with
+	* generic/tclListObj.c:	TclMaxListLength() which is the function we
+	* generic/tclUtil.c:	actually want.
+	* generic/tclCompCmdsSZ.c:
+
+	* generic/tclCompCmdsSZ.c: Rewrite of parts of the switch compiler to
+	better use the powers of TclFindElement() and do less parsing on its
+	own.
+
+2011-04-28  Don Porter  <dgp@users.sourceforge.net>

+
+2011-03-27  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c (TclNREvalObjEx): fix performance issue, notably

+
+2011-03-20  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclThreadAlloc.c: Imported HAVE_FAST_TSD support from

+	support has been added. It is not clear how universal a build using
+	this will be: it also requires some loader support.

+
+2011-03-14  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tools/tclZIC.tcl (onDayOfMonth): Allow for leading zeroes in month

+
+	* generic/tclAssembly.c (BBEmitInstInt1): Changed parameter data types
+	in an effort to silence a MSVC warning reported by Ashok P. Nadkarni.
+	Unable to test, since both forms work on my machine in VC2005, 2008,
+	2010, in both release and debug builds.
+	* tests/tclTest.c (TestdstringCmd): Restored MSVC buildability broken
+	by [5574bdd262], which changed the effective return type of 'ckalloc'
+	from 'char*' to 'void*'.
+
+2011-03-13  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: remove TEBCreturn()
+
+2011-03-12  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tcl.h (ckalloc,ckfree,ckrealloc): Moved casts into these
+	macro so that they work with VOID* (which is a void* on all platforms
+	which Tcl actually builds on) and unsigned int for the length
+	parameters, removing the need for MANY casts across the rest of Tcl.
+	Note that this is a strict source-level-only change, so size_t cannot
+	be used (would break binary compatibility on 64-bit platforms).

+	Converted the [namespace] command into an ensemble. This has the
+	consequence of making it vital for Tcl code that wishes to work with
+	namespaces to _not_ delete the ::tcl namespace.
+	***POTENTIAL INCOMPATIBILITY***
+
+	* library/tcltest/tcltest.tcl (loadIntoSlaveInterpreter): Added this
+	command to handle connecting tcltest to a slave interpreter. This adds
+	in the hook (inside the tcltest namespace) that allows the tests run
+	in the child interpreter to be reported as part of the main sequence
+	of test results. Bumped version of tcltest to 2.3.3.
+	* tests/init.test, tests/package.test: Adapted these test files to use

+	adds test cases to util.test for correct rounding in difficult cases
+	of TclDoubleDigits where fixed- precision results are requested. (e)
+	adds test cases to util.test for the controversial aspects of [Bug
+	3105247]. As a side effect, two more modules from libtommath

+	TIP #162 IMPLEMENTATION
+
+	* doc/socket.n:		Document the changes to the [socket] and

+
+	* generic/tclInt.h:	Introduce TclCreateSocketAddress() as a
+	* generic/tclIOSock.c:	replacement for the platform-dependent

+	* unix/tclUnixChan.c:	the [socket] and [fconfigure] commands to

+
+2010-09-28  Kevin B. Kenny  <kennykb@acm.org>
+
+	[dogeen-assembler-branch]
+
+	* tests/assemble.test: Added more "white box" tests.
+	* generic/tclAssembly.c: Added the error checking and reporting
+	for undefined labels. Revised code so that no pointers into the
+	bytecode sequence are held (because the sequence can move!),
+	that no Tcl_HashEntry pointers are held (because the hash table
+	doesn't guarantee their stability!) and to eliminate the BBHash
+	table, which is merely additional information indexed by jump
+	labels and can just as easily be held in the 'label' structure.
+	Renamed shared structures to CamelCase, and renamed 'label' to
+	JumpLabel because other types of labels may eventually be possible.
+
+2010-09-27  Kevin B. Kenny  <kennykb@acm.org>
+
+	[dogeen-assembler-branch]
+
+	* tests/assemble.test: Added more "white box" tests.
+	* generic/tclAssembly.c: Fixed bugs exposed by the new tests.
+	(a) [eval] and [expr] had incorrect stack balance computed if
+	the arg was not a simple word. (b) [concat] accepted a negative
+	operand count. (c) [invoke] accepted a zero or negative operand
+	count. (d) more misspelt error messages.
+	Also replaced a funky NRCallTEBC with the new call
+	TclNRExecuteByteCode, necessitated by a merge with changes on the
+	HEAD.
+
+2010-09-26  Miguel Sofer  <msofer@users.sf.net>
+

+	* generic/tclCompile.h:  to be a normal NRE citizen: it loses its
+	* generic/tclExecute.c:  special status.
+	* generic/tclInt.decls:  The logic flow within the BC engine is

+2010-09-26  Kevin B. Kenny  <kennykb@acm.org>
+
+	[dogeen-assembler-branch]
+
+	* tests/assemble.test:	Added many new tests moving toward a more

+	* generic/tclAssembly.c:	Fixed bugs exposed by the new tests:
+	(a) [bitnot] and [not] had incorrect operand counts. (b)
+	INST_CONCAT cannot concatenate zero objects. (c) misspelt error
+	messages. (d) the "assembly code" internal representation lacked
+	a duplicator, which caused double-frees of the Bytecode object
+	if assembly code ever was duplicated.
+
+2010-09-25  Kevin B. Kenny   <kennykb@acm.org>
+
+	[dogeen-assembler-branch]
+
+	* generic/tclAssembly.c:	Massive refactoring of the assembler
+	* generic/tclAssembly.h:	to use a Tcl-like syntax (and use
+	* tests/assemble.test:		Tcl_ParseCommand to parse it). The
+	* tests/assemble1.bench:	refactoring also ensures that
+	Tcl_Tokens in the assembler have string ranges inside the source
+	code, which allows for [eval] and [expr] assembler directives
+	that simply call TclCompileScript and TclCompileExpr recursively.
+
+2010-09-24  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tests/stringComp.test: improved string eq/cmp test coverage
+	* generic/tclExecute.c (TclExecuteByteCode): merge INST_STR_CMP and

+
+	* tests/execute.test: Added execute-10.3 for [Bug 3072640]. The test
+	causes a mem failure.
+
+	* generic/tclExecute: Protect all possible writes to ::errorInfo or

+
+	* generic/tclIORTrans.c (ForwardProc): [Bug 2964425]: When cleaning

+	required removing an extra Tcl_DecrRefCount too.
+
+	* generic/tclOO.h, generic/tclOOInt.h: [Patch 2961556]: Change TclOO
+	to use the same style of function typedefs as Tcl, as this is about

+
+	***POTENTIAL INCOMPATIBILITY***
+	Source code that uses function typedefs from TclOO will need to update
+	variables and argument definitions so that pointers to the function
+	values are used instead. Binary compatibility is not affected.
+
+	* generic/*.c, generic/tclInt.h, unix/*.c, macosx/*.c: Applied results
+	of doing a Code Audit. Principal changes:
+	  * Use do { ... } while (0) in macros
+	  * Avoid shadowing one local variable with another
+	  * Use clearer 'foo.bar++;' instead of '++foo.bar;' where result not
+	    required (i.e., semantically equivalent); clarity is increased
+	    because it is bar that is incremented, not foo.
+	  * Follow Engineering Manual rules on spacing and declarations
+
+2010-03-04  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclOO.c (ObjectRenamedTrace): [Bug 2962664]: Add special

+
+	* generic/tclOOInt.h (ROOT_CLASS): Add new flag for specially marking
+	the root class. Simpler and more robust than the previous technique.

+	* generic/tclCmdMZ.c (StringFirstCmd, StringLastCmd): [Bug 2960021]:
+	Only search for the needle in the haystack when the needle isn't

+	happening when things get mixed up (a common programming error).
+
+	* generic/tclMain.c (Tcl_Main): [Bug 801429]: Factor out the holding
+	of the client-installed main loop function into thread-specific data.
+
+	***POTENTIAL INCOMPATIBILITY***
+	Code that previously tried to set the main loop from another thread
+	will now fail. On the other hand, there is a fairly high probability
+	that such programs would have been failing before due to the lack of
+	any kind of inter-thread memory barriers guarding accesses to this
+	part of Tcl's state.

+	Many thanks to Jean-Claude Wippler for finding this.
+
+	* generic/tclExecute.c (TclExecuteByteCode): Reduce ifdef-fery and

+
+	* doc/socket.n: [Bug 2957688]: Clarified that [socket -server] works

+
+2010-02-22  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclZlib.c (ZlibTransformInput): [Bug 2762041]: Added a hack
+	to work around the general problem, early EOF recognition based on the
+	base-channel, instead of the data we have ready for reading in the
+	transform. Long-term we need a proper general fix (likely tracking EOF
+	on each level of the channel stack), with attendant complexity.
+	Furthermore, Z_BUF_ERROR can be ignored, and must be when feeding the
+	zlib code with single characters.

+
+	* generic/tclHash.c (HashStringKey):	Restore these hash functions
+	* generic/tclLiteral.c (HashString):	to use the classic algorithm.
+	* generic/tclObj.c (TclHashObjKey):	Community felt normal case
+	speed to be more important than resistance to malicious cases. For
+	now, hashes that need to deal with the malicious case can use a custom
+	hash table and install their own hash function, though that is not
+	functionality exposed to the script level.
+
+	* generic/tclCompCmds.c (TclCompileDictUpdateCmd): Stack depth must be
+	correctly described when compiling a body to prevent crashes in some

+
+	* generic/tclOO.c (AllocObject, SquelchedNsFirst, ObjectRenamedTrace):
+	* generic/tclNamesp.c (Tcl_DeleteNamespace): [Bug 2950259]: Revised
+	the namespace deletion code to provide an additional internal callback
+	that gets triggered early enough in namespace deletion to allow TclOO
+	destructors to run sanely. Adjusted TclOO to take advantage of this,
+	so making tearing down an object by killing its namespace appear to
+	work seamlessly, which is needed for Itcl. (Note that this is not a
+	feature that will ever be backported to 8.5, and it remains not a
+	recommended way of deleting an object.)
+
+2010-02-13  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileSwitchCmd): Divided the [switch]
+	compiler into three pieces (after the model of [try]): a parser, an
+	instruction-issuer for chained tests, and an instruction-issuer for
+	jump tables.
+
+	* generic/tclEnsemble.c: Split the ensemble engine out into its own
+	file rather than keeping it mashed together with the namespace code.
+
+2010-02-12  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* win/tcl.m4:		Use -pipe for gcc on win32

+
+2010-02-11  Mo DeJong  <mdejong@users.sourceforge.net>

+
+2010-02-11  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclIOCmd.c (Tcl_OpenObjCmd): [Bug 2949740]: Make sure that
+	we do not try to put a NULL pipeline channel into binary mode.
+
+2010-02-11  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	[Bug 2826551, Patch 2948425]: Assorted regexp bugs related to -all,
+	-line and -start options and newlines.
+	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd): If -offset is given, treat it
+	as the start of the line if the previous character was a newline. Fix
+	nasty edge case where a zero length match would not advance the index.
+	* tests/regexp.test: Add regression tests back ported from Jacl.
+	Checks for a number of issues related to -line and newline handling. A
+	few of tests were broken before the patch and continue to be broken,
+	marked as knownBug.
+
+2010-02-11  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclOO.c (ObjectRenamedTrace): [Bug 2949397]: Prevent
+	destructors from running on the two core class objects when the whole
+	interpreter is being destroyed.
+
+2010-02-09  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileTryCmd, IssueTryInstructions)
+	(IssueTryFinallyInstructions): Added compiler for the [try] command.
+	It is split into three pieces that handle the parsing of the tokens,
+	the issuing of instructions for finally-free [try], and the issuing of
+	instructions for [try] with finally; there are enough differences
+	between the all cases that it was easier to split the code rather than
+	have a single function do the whole thing.
+
+2010-02-09  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>
+
+	* tools/genStubs.tcl: Remove dependency on 8.5+ idiom "in" in
+	expressions.
+
+2010-02-08  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclZlib.c (Tcl_ZlibDeflate, Tcl_ZlibInflate): [Bug 2947783]:
+	Make sure that the result is an unshared object before appending to it
+	so that nothing crashes if it is shared (use in Tcl code was not
+	affected by this, but use from C was an issue).
+
+2010-02-06  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclHash.c (HashStringKey):	Replace Tcl's crusty old hash
+	* generic/tclObj.c (TclHashObjKey):	function with the algorithm
+	due to Fowler, Noll and Vo. This is slightly faster (assuming the
+	presence of hardware multiply) and has somewhat better distribution
+	properties of the resulting hash values. Note that we only ever used
+	the 32-bit version of the FNV algorithm; Tcl's core hash engine
+	assumes that hash values are simple unsigned ints.
+
+	***POTENTIAL INCOMPATIBILITY***
+	Code that depends on hash iteration order (especially tests) may well
+	be disrupted by this. Where a definite order is required, the fix is
+	usually to just sort the results after extracting them from the hash.
+	Where this is insufficient, the code that has ceased working was
+	always wrong and was only working by chance.
+
+2010-02-05  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileErrorCmd): Added compilation of the

+
+2010-02-05  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* tools/genStubs.tcl:	Follow-up to earlier commit today:

+
+	* generic/tclOOBasic.c (TclOO_Object_Destroy): Rewrote to be NRE-aware
+	when calling destructors. Note that there is no guarantee that

+	of the 'destroy' method only.
+
+	* generic/tclEncoding.c: Add 'const' to many function-internal vars

+
+2010-02-05  Jan Nijtmans  <nijtmans@users.sf.net>

+2010-02-04  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclVar.c: Added more use of error-codes and reduced the
+	stack overhead of older interfaces.
+	(ArrayGetCmd): Stop silly crash when using a trivial pattern due to
+	error in conversion to ensemble.

+
+	* generic/tclVar.c: Turned the [array] command into a true ensemble.
+
+	* generic/tclOO.c (AllocObject, MyDeleted): A slightly faster way to
+	handle the deletion of [my] is with a standard delete callback. This
+	is because it doesn't require an additional memory allocation during
+	object creation. Also reduced the amount of string manipulation
+	performed during object creation to further streamline memory
+	handling; this is not backported to the 8.5 package as it breaks a
+	number of abstractions.
+
+	* generic/tclOOBasic.c (TclOO_Object_Destroy): [Bug 2944404]: Do not
+	crash when a destructor deletes the object that is executing that
+	destructor.
+
+2010-02-01  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclVar.c (Tcl_ArrayObjCmd): [Bug 2939073]: Stop the [array

+	trace deletes the element that is going to be processed next. Many
+	thanks to Alexandre Ferrieux for the bulk of this fix.
+
+	* generic/regexec.c (ccondissect, crevdissect): [Bug 2942697]: Rework

+2010-01-29  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tcl.h: [Bug 2942081]: Reverted Tcl_ThreadDataKey type change
+				Changed some Tcl_CallFrame fields from "char *"
+				to "void *". This saves unnecessary space on
+				Cray's (and it's simply more correct).
+
+	* tools/genStubs.tcl:	No longer generate a space after "*" and
+				immediately after a function name, so the
+				format of function definitions in tcl*Decls.h
+				match all other tcl*.h header files.
+	* doc/ParseArgs.3:	Change Tcl_ArgvFuncProc, Tcl_ArgvGenFuncProc
+	* generic/tcl.h:	and GetFrameInfoValueProc to be function

+2010-01-28  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclOOBasic.c (TclOO_Object_Destroy): Move the execution of
+	destructors to a point where they can produce an error. This will not
+	work for all destructors, but it does mean that more failing calls of
+	them will be caught.
+	* generic/tclOO.c (AllocObject, MyDeletedTrace, ObjectRenamedTrace):
+	(ObjectNamespaceDeleted): Stop various ways of getting at commands
+	with dangling pointers to the object. Also increases the reliability
+	of calling of destructors (though most destructors won't benefit; when
+	an object is deleted namespace-first, its destructors are not run in a
+	nice state as the namespace is partially gone).

+
+	* generic/tclIO.c (CreateScriptRecord): [Bug 2918110]: Initialize
+	the EventScriptRecord (esPtr) fully before handing it to
+	Tcl_CreateChannelHandler for registration. Otherwise a reflected

+	'watchProc' will cause the function 'TclChannelEventScriptInvoker'
+	to be run on an uninitialized structure.
+
+2010-01-18  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclStringObj.c (Tcl_AppendFormatToObj): [Bug 2932421]: Stop

+
+	* win/tclAppInit.c (Tcl_AppInit): [Bug 2902965]: Reverted Jan's change
+	that added a call to Tcl_InitStubs. The 'tclsh' and 'tcltest' programs
+	are providers, not consumers of the Stubs table, and should not link
+	with the Stubs library, but only with the main Tcl library. (In any
+	case, the presence of Tcl_InitStubs broke the build.)

+2009-11-24  Andreas Kupries  <andreask@activestate.com>
+
+	* library/tclIndex: Manually redone the part of tclIndex dealing with

+	automatic regeneration of this part is not possible because it wrongly
+	puts 'safe::Setup' on the list, and wrongly leaves out 'safe::Log'
+	which is more dynamically created than the generator expects.
+
+	Further note that the file "clock.tcl" is explicitly loaded by
+	"init.tcl", the first time the clock command is invoked. The relevant
+	code can be found at line 172ff, roughly, the definition of the
+	procedure 'clock'. This means none of the procedures of this file
+	belong in the tclIndex. Another indicator that automatic regeneration

+
+2009-11-06  Andreas Kupries  <andreask@activestate.com>
+
+	* library/safe.tcl (::safe::Setup): Added documentation of the
+	contents of the state array. Also killed the 'InterpState' procedure

+	with 'namespace upvar'.
+
+2009-11-05  Andreas Kupries  <andreask@activestate.com>
+
+	* library/safe.tcl: A series of patches which bring the SafeBase up to
+	date with code guidelines, Tcl's features, also eliminating a number
+	of inefficiencies along the way.
+	(1) Changed all procedure names to be fully qualified.
+	(2) Moved the procedures out of the namespace eval. Kept their
+	locations. IOW, broke the namespace eval apart into small sections not
+	covering the procedure definitions.
+	(3) Reindented the code. Just lots of whitespace changes.
+	Functionality unchanged.
+	(4) Moved the multiple namespace eval's around. Command export at the
+	top, everything else (var decls, argument parsing setup) at the
+	bottom.
+	(5) Moved the argument parsing setup into a procedure called when the
+	code is loaded. Easier management of temporary data.
+	(6) Replaced several uses of 'Set' with calls to the new procedure
+	'InterpState' and direct access to the per-slave state array.
+	(7) Replaced the remaining uses of 'Set' and others outside of the
+	path/token handling, and deleted a number of procedures related to
+	state array access which are not used any longer.
+	(8) Converted the path token system to cache normalized paths and path
+	<-> token conversions. Removed more procedures not used any longer.
+	Removed the test cases 4.3 and 4.4 from safe.test. They were testing
+	the now deleted command "InterpStateName".
+	(9) Changed the log command setup so that logging is compiled out
+	completely when disabled (default).
+	(10) Misc. cleanup. Inlined IsInterp into CheckInterp, its only user.
+	Consistent 'return -code error' for error reporting. Updated to use
+	modern features (lassign, in/ni, dicts). The latter are used to keep a
+	reverse path -> token map and quicker check of existence.
+	(11) Fixed [Bug 2854929]: Recurse into all subdirs under all TM root
+	dirs and put them on the access path.
+
+2009-11-02  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/tzdata/Asia/Novokuznetsk: New tzdata locale for Kemerovo

+
+2009-11-01  Joe Mistachkin  <joe@mistachkin.com>
+
+	* doc/Cancel.3: Minor cosmetic fixes.
+	* win/makefile.vc: Make htmlhelp target work again.  An extra set of
+	double quotes around the definition of the HTML help compiler tool
+	appears to be required.  Previously, there was one set of double
+	quotes around the definition of the tool and one around the actual
+	invocation.  This led to confusion because it was the only such tool
+	path to include double quotes around its invocation.  Also, it was
+	somewhat inflexible in the event that somebody needed to override the
+	tool command to include arguments.  Therefore, even though it may look
+	"wrong", there are now two double quotes on either side of the tool
+	path definition.  This fixes the problem that currently prevents the
+	htmlhelp target from building and maintains flexibility in case
+	somebody needs to override it via the command line or an environment
+	variable.
+
+2009-11-01  Joe English  <jenglish@users.sourceforge.net>
+
+	* doc/Eval.3, doc/Cancel.3: Move TIP#285 routines out of Eval.3 into

+
+2009-10-30  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* tests/tcltest.test: When creating the notwritabledir we deny the
+	current user access to delete the file. We must grant this right when
+	we cleanup. Required on Windows 7 when the user does not automatically
+	have administrator rights.
+
+2009-10-29  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tcl.h:        Changed the typedef for the mp_digit type
+	from:
+		typedef unsigned long mp_digit;
+	to:
+		typedef unsigned int mp_digit;
+	For 32-bit builds where "long" and "int" are two names for the same
+	thing, this is no change at all.  For 64-bit builds, though, this
+	causes the dp[] array of an mp_int to be made up of 32-bit elements
+	instead of 64-bit elements.  This is a huge improvement because
+	details elsewhere in the mp_int implementation cause only 28 bits of
+	each element to be actually used storing number data.  Without this
+	change bignums are over 50% wasted space on 64-bit systems.  [Bug
+	2800740].
+
+	***POTENTIAL INCOMPATIBILITY***
+	For 64-bit builds, callers of routines with (mp_digit) or (mp_digit *)
+	arguments *will*, and callers of routines with (mp_int *) arguments
+	*may* suffer both binary and stubs incompatibilities with Tcl releases
+	8.5.0 - 8.5.7.  Such possibilities should be checked, and if such
+	incompatibilities are present, suitable [package require] requirements
+	on the Tcl release should be put in place to keep such built code
+	[load]-ing only in Tcl interps that are compatible.

+
+	* tests/dict.test: Make variable-clean and simplify tests by utilizing

+2009-10-28  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclLiteral.c:	[Bug 2888044]: Fixed 2 bugs.
+	* tests/info.test:	First, as noted in the comments of the
+	TclCleanupLiteralTable routine, since the teardown of the intrep of
+	one Tcl_Obj can cause the teardown of others in the same table, the
+	full table cleanup must be done with care, but the code did not
+	contain the same care demanded in the comment.  Second, recent
+	additions to the info.test file had poor hygiene, leaving an array
+	variable ::a lying around, which breaks later interp.test tests during
+	a -singleproc 1 run of the test suite.
+
+2009-10-28  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tests/fileName.test (fileName-20.[78]): Corrected poor test

+	reopened).

+
+	* generic/tclIO.c (FlushChannel): Skip OutputProc for low-level

+2009-10-20  Don Porter  <dgp@users.sourceforge.net>
+
+	* unix/Makefile.in:	Removed the long outdated and broken targets

+
+2009-10-19  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclIO.c:      [Patch 2107634]: Revised ReadChars and

+
+2009-10-06  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclInterp.c (SlaveEval): Agressive stomping of internal reps

+
+2009-10-05  Andreas Kupries  <andreask@activestate.com>

+2009-09-17  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclCompile.c:	Re-implement Tcl_SubstObj() as a simple
+	* generic/tclParse.c:	wrapper around TclNRSubstObj().  This has
+	* tests/basic.test:	the effect of caching compiled bytecode in
+	* tests/parse.test:	the value to be substituted.  Note that

+	only by Tcl_EvalEx() and Tcl_ParseVar() so tests aiming to test its

+
+	Extended the bytecode compiler initialization to recognize the
+	compilation of whole files (NRE enabled 'source' command) and switch
+	to the counting of absolute lines in that case.
+
+	Further extended the bytecode compiler to track the start line in the
+	generated information, and modified the bytecode execution to
+	recompile an object if the location as per the calling context doesn't
+	match the location saved in the bytecode. This part could be optimized
+	more by using more memory to keep all possibilities which occur
+	around, or by just adjusting the location information instead of a
+	total recompile.
+
+	Reworked the handling of literal command arguments in bytecode to be
+	saved (compiler) and used (execution) per command (See the
+	TCL_INVOKE_STK* instructions), and not per the whole bytecode. This,
+	and the previous change remove the problems with location data caused
+	by literal sharing (across whole files, but also proc bodies).
+	Simplified the associated datastructures (ExtIndex is gone, as is the
+	function EnterCmdWordIndex).
+
+	The last change causes the hashtable 'lineLABCPtr' to be state which
+	has to be kept per coroutine, like the CmdFrame stack. Reworked the
+	coroutine support code to create, delete and switch the information as
+	needed. Further reworked the tailcall command as well, it has to pop
+	its own arguments when run in a bytecode context to keep a proper
+	stack in 'lineLABCPtr'.
+
+	Fixed the mishandling of line information in the NRE-enabled 'for' and
+	'while' commands introduced when both were made to share their
+	iteration callbacks without taking into account that the loop body is
+	found in different words of the command. Introduced a separate data
+	structure to hold all the callback information, as we went over the
+	limit of 4 direct client-data values for NRE callbacks.
+
+	The above fixes [Bug 1605269].

+
+2009-02-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c:	Several revisions to the shimmering
+	patterns between Unicode and UTF string reps.  Most notably the
+	call: objPtr = Tcl_NewUnicodeObj(...,0); followed by a loop of calls:
+	Tcl_AppendUnicodeToObj(objPtr, u, n); will now grow and append to
+	the Unicode representation.  Before this commit, the sequence would
+	convert each append to UTF and perform the append to the UTF rep.
+	This is puzzling and likely a bug.  The performance of [string map]
+	is significantly improved by this change (according to the MAP
+	collection of benchmarks in tclbench).  Just in case there was some
+	wisdom in the old ways that I missed, I left in the ability to restore
+	the old patterns with a #define COMPAT 1 at the top of the file.

+
+	* generic/tclPathObj.c:	[Bug 2571597]: Fixed mistaken logic in

+	where "volumerelative" is another possibility.
+
+2009-02-18  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c:	Simplify the logic of the
+	Tcl_*SetObjLength() routines.
+
+	* generic/tclStringObj.c:	Rewrite GrowStringBuffer() so that it
+	has parallel structure with GrowUnicodeBuffer().  The revision permits
+	allocation attempts to continue all the way up to failure, with no
+	gap. It also directly manipulates the String and Tcl_Obj internals
+	instead of inefficiently operating via Tcl_*SetObjLength() with all of
+	its extra protections and underdocumented special cases.
+
+	* generic/tclStringObj.c:	Another round of simplification on
+	the allocation macros.
+
+2009-02-17  Jeff Hobbs  <jeffh@ActiveState.com>

+	Use 'd'ebug runtime in 64-bit builds.
+
+2009-02-17  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c:	Pare back the length of the unicode
+	array in a non-extended String struct to one Tcl_UniChar, meant to
+	hold the terminating NUL character.  Non-empty unicode strings are
+	then stored by extending the String struct by stringPtr->maxChars
+	additional slots in that array with sizeof(Tcl_UniChar) bytes per
+	slot. This revision makes the allocation macros much simpler.
+
+	* generic/tclStringObj.c:	Factor out common GrowUnicodeBuffer()
+	and solve overflow and growth algorithm fallbacks in it.
+
+	* generic/tclStringObj.c:	Factor out common GrowStringBuffer().
+
+	* generic/tclStringObj.c:	Convert Tcl_AppendStringsToObj into
+	* tests/stringObj.test:		a radically simpler implementation
+	where we just loop over calls to Tcl_AppendToObj.  This fixes [Bug
+	2597185].  It also creates a *** POTENTIAL INCOMPATIBILITY *** in
+	that T_ASTO can now allocate more space than is strictly required,
+	like all the other Tcl_Append* routines.  The incompatibility was
+	detected by test stringObj-6.5, which I've updated to reflect the
+	new behavior.
+
+	* generic/tclStringObj.c:	Revise buffer growth implementation
+	in ExtendStringRepWithUnicode.  Use cheap checks to determine that
+	no reallocation is necessary without cost of computing the precise
+	number of bytes needed.  Also make use of the string growth algortihm
+	in the case of repeated appends.

+	* tests/stringObj.test:		(some part of) a Tcl_Obj to itself.
+	Added the appendself and appendself2 subcommands to the

+
+	* generic/tclStringObj.c:	Factor out duplicate code from
+	Tcl_AppendObjToObj.
+
+	* generic/tclStringObj.c:	Replace the 'size_t uallocated' field
+	of the String struct, storing the number of bytes allocated to store
+	the Tcl_UniChar array, with an 'int maxChars' field, storing the
+	number of Tcl_UniChars that may be stored in the allocated space.
+	This reduces memory requirement a small bit, and makes some range
+	checks simpler to code.
+	* generic/tclTestObj.c:	Replace the [teststringobj ualloc] testing
+	* tests/stringObj.test:	command with [teststringobj maxchars] and
+	update the tests.
+
+	* generic/tclStringObj.c:	Removed limitation in
+	Tcl_AppendObjToObj where the char length of the result was only
+	computed if the appended string was all single byte characters.
+	This limitation was in place to dodge a bug in Tcl_GetUniChar.
+	With that bug gone, we can take advantage of always recording the
+	length of append results when we know it.
+
+2009-02-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c:	Revisions so that we avoid creating
+	the strange representation of an empty string with
+	objPtr->bytes == NULL and stringPtr->hasUnicode == 0.  Instead in
+	the situations where that was being created, create a traditional
+	two-legged stork representation (objPtr->bytes = tclEmptyStringRep
+	and stringPtr->hasUnicode = 1).  In the situations where the strange
+	rep was treated differently, continue to do so by testing
+	stringPtr->numChars == 0 to detect it.  These changes make the code
+	more conventional so easier for new maintainers to pick up.  Also
+	sets up further simplifications.
+
+	* generic/tclTestObj.c:	Revise updates to [teststringobj] so we don't
+	get blocked by MODULE_SCOPE limits.
+
+2009-02-12  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c:	Rewrites of the routines
+	Tcl_GetCharLength, Tcl_GetUniChar, Tcl_GetUnicodeFromObj,
+	Tcl_GetRange, and TclStringObjReverse to use the new macro, and
+	to more simply and clearly split the cases depending on whether
+	a valid unicode rep is present or needs to be created.
+	New utility routine UnicodeLength(), to compute the length of unicode
+	buffer arguments when no length is passed in, with built-in
+	overflow protection included.  Update three callers to use it.
+
+	* generic/tclInt.h:	New macro TclNumUtfChars meant to be a faster
+	replacement for a full Tcl_NumUtfChars() call when the string has all
+	single-byte characters.
+
+	* generic/tclStringObj.c:	Simplified Tcl_GetCharLength by
+	* generic/tclTestObj.c:		removing code that did nothing.
+	Added early returns from Tcl_*SetObjLength when the desired length
+	is already present; adapted test command to the change.
+
+	* generic/tclStringObj.c:	Re-implemented AppendUtfToUnicodeRep
+	so that we no longer pass through Tcl_DStrings which have their own
+	sets of problems when lengths overflow the int range.  Now AUTUR and

+
+	* generic/tclStringObj.c:	Changed type of the 'allocated' field

+	* generic/tclOODefineCmds.c (Tcl_ClassSetConstructor):
+	[Bug 2531577]: Ensure that caches of constructor chains are cleared
+	when the constructor is changed.
+
+2009-01-26  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>
+
+	* generic/tclInt.h:   [Bug 1028264]: WSACleanup() too early.
+	* generic/tclEvent.c: The fix introduces "late exit handlers" for
+	* win/tclWinSock.c:   similar late process-wide cleanups.
+
+2009-01-26  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>
+
+	* win/tclWinSock.c: [Bug 2446662]: Resync Win behavior on RST with
+	that of unix (EOF).
+
+2009-01-26  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclZlib.c (ChanClose): [Bug 2536400]: Only generate error
+	messages in the interpreter when the thread is not being closed down.
+
+2009-01-23  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/zlib.n: Added a note that 'zlib push' is reversed by 'chan pop'.
+
+2009-01-22  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclCompile.h:	CONSTify TclPrintInstruction (TIP #27)
+	* generic/tclCompile.c
+	* generic/tclInt.h:	CONSTify TclpNativeJoinPath (TIP #27)
+	* generic/tclFileName.c
+	* generic/tcl.decls:	{unix win} is equivalent to {generic}
+	* generic/tclInt.decls
+	* generic/tclDecls.h:	(regenerated)
+	* generic/tclIntDecls.h
+	* generic/tclGetDate.y:	Single internal const decoration.
+	* generic/tclDate.c:
+
+2009-01-22  Kevin B. Kenny  <kennykb@acm.org>
+
+	* unix/tcl.m4: Corrected a typo ($(SHLIB_VERSION) should be
+	${SHLIB_VERSION}).
+	* unix/configure: Autoconf 2.59
+
+2009-01-21  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIORChan.c (ReflectClose): [Bug 2458202]:
+	* generic/tclIORTrans.c (ReflectClose): Closing a channel may supply
+	NULL for the 'interp'. Test for finalization needs to be different,
+	and one place has to pull the interp out of the channel instead.
+
+2009-01-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c: New fix for [Bug 2494093] replaces the
+	flawed attempt committed 2009-01-09.
+
+2009-01-19  Kevin B. Kenny  <kennykb@acm.org>
+
+	* unix/Makefile.in: [Patch 907924]:Added a CONFIG_INSTALL_DIR
+	* unix/tcl.m4:      parameter so that distributors can control where
+	tclConfig.sh goes. Made the installation of 'ldAix' conditional upon
+	actually being on an AIX system. Allowed for downstream packagers to
+	customize SHLIB_VERSION on BSD-derived systems. Thanks to Stuart
+	Cassoff for his help.
+	* unix/configure: Autoconf 2.59
+
+2009-01-19  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/build.vc.bat: Improved tools detection and error message
+	* win/makefile.vc: Reorganized the $(TCLOBJ) file list into seperate
+	parts for easier maintenance. Matched all sources built using -GL to
+	both $(lib) and $(link) to use -LTCG and avoid a warning message.
+	Addressed the over-building nature of the htmlhelp target by moving
+	from a pseudo target to a real target dependent on the entire docs/
+	directory contents.
+	* win/nmakehlp.c: Removed -g option and GrepForDefine() func as it
+	isn't being used anymore. The -V option method is much better.
+
+2009-01-16  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tcl.h:	Bump patchlevel to 8.6b1.1 to distinguish
+	* library/init.tcl:	CVS snapshots from the 8.6b1 and 8.6b2 releases
+	* unix/configure.in:	and to deal with the fact that the 8.6b1
+	* win/configure.in:	version of init.tcl will not [source] in the
+	HEAD version of Tcl.
+
+	* unix/configure:	autoconf-2.59
+	* win/configure:
+
+2009-01-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (Tcl_DeleteCommandFromToken):	Reverted most
+	of the substance of my 2009-01-12 commit. NULLing the objProc field of
+	a Command when deleting it is important so that tests for certain
+	classes of commands don't return false positives when applied to
+	deleted command tokens. Overall change is now just replacement of a
+	false comment with a true one.
+
+2009-01-13  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* unix/tcl.m4: [Bug 2502365]: Building of head on HPUX is broken when
+	using the native CC.
+	* unix/configure (autoconf-2.59)
+
+2009-01-13  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCmdMZ.c (Tcl_ThrowObjCmd):	Move implementation of [throw]
+	* library/init.tcl (throw):		to C from Tcl.
+
+2009-01-12  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (Tcl_DeleteCommandFromToken): One consequence of
+	the NRE rewrite is that there are now situations where a NULL objProc
+	field in a Command struct is perfectly normal. Removed an outdated
+	comment in Tcl_DeleteCommandFromToken that claimed we use
+	cmdPtr->objPtr==NULL as a test of command validity. In fact we use
+	cmdPtr->flags&CMD_IS_DELETED to perform that test. Also removed the
+	setting to NULL, since any extension following the advice of the old
+	comment is going to be broken by NRE anyway, and needs to shift to
+	flag-based testing (or stop intruding into such internal matters).
+	Part of [Bug 2486550].
+
+2009-01-09  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c (STRING_SIZE): [Bug 2494093]: Corrected
+	failure to limit memory allocation requests to the sizes that can be
+	supported by Tcl's memory allocation routines.
+
+2009-01-09  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclNamesp.c (NamespaceEnsembleCmd): [Bug 1558654]: Error out
+	when someone gives wrong # of args to [namespace ensemble create].
+
+2009-01-08  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c (STRING_UALLOC): [Bug 2494093]: Added missing
+	parens required to get correct results out of things like
+	STRING_UALLOC(num + append).
+
+2009-01-08  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c, generic/tclIndexObj.c, generic/tclListObj.c,
+	* generic/tclObj.c, generic/tclStrToD.c, generic/tclUtil.c,
+	* generic/tclVar.c: Generate errorcodes for the error cases which
+	approximate to "I can't interpret that string as one of those" and
+	"You gave me the wrong number of arguments".
+
+2009-01-07  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/dict.n: [Tk Bug 2491235]: Added more examples.
+
+	* tests/oo.test (oo-22.1): Adjusted test to be less dependent on the
+	specifics of how [info frame] reports general frame information, and
+	instead to focus on what methods add to it; that's really what the
+	test is about anyway.
+
+2009-01-06  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/stringObj.test:	Revise tests that demand a NULL Tcl_ObjType
+	in certain values to construct those values with [testdstring] so
+	there's no lack of robustness depending on the shimmer history of
+	shared literals.
+
+2009-01-06  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c (DictIncrCmd): Corrected twiddling in internals
+	of dictionaries so that literals can't get destroyed.
+
+	* tests/expr.test: [Bug 2006879]: Eliminate non-ASCII char.
+
+	* generic/tclOOInfo.c (InfoObjectMethodsCmd,InfoClassMethodsCmd):
+	[Bug 2489836]: Only delete pointers that were actually allocated!
+
+	* generic/tclOO.c (TclNRNewObjectInstance, Tcl_NewObjectInstance):
+	[Bug 2481109]: Perform search for existing commands in right context.
+
+2009-01-05  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCmdMZ.c (TclNRSourceObjCmd): [Bug 2412068]: Make
+	* generic/tclIOUtil.c (TclNREvalFile):    implementation of the
+	[source] command be NRE enabled so that [yield] inside a script
+	sourced in a coroutine can work.
+
+2009-01-04  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCmdAH.c: Tidy up spacing and code style.
+
+2009-01-03  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl (tcl::clock::add): Fixed error message formatting
+	in the case where [clock add] is presented with a bad switch.
+	* tests/clock.test (clock-65.1) Added a test case for the above
+	problem [Bug 2481670].
+
+2009-01-02  Donal K. Fellows  <dkf@users.sf.net>
+
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): [Bug 878333]: Force the use of the
+	compatibility version of mkstemp() on IRIX.
+	* unix/configure.in, unix/Makefile.in (mkstemp.o):
+	* compat/mkstemp.c (new file): [Bug 741967]: Added a compatibility
+	implementation of the mkstemp() function, which is apparently needed
+	on some platforms.

+	problems with vfork. Users that still want vfork can add -Dfork=vfork
+	to the compile flags. [Bug 942 2228 1312]

+
+	* win/tcl16.rc:

+
+1999-12-07  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tests/io.test: removed 'knownBug' tests that were for unsupported0,
+	which is now fcopy (that already has tests)
+
+	* mac/tclMacPort.h: added utime.h include
+
+	* generic/tclDate.c:
+	* unix/Makefile.in: fixed make gendate to swap const with CONST so it
+	uses the Tcl defined CONST type [Bug 3521]
+
+	* generic/tclIO.c: removed panic that could occur in FlushChannel when
+	a "blocking" channel would receive EAGAIN, instead treating it the

+	the end of the counted string. [Bug 3336]
+
+1999-12-03  Jeff Hobbs  <hobbs@scriptics.com>
+

+	to simplify type handling. [Bug 2467]
+
+	* tests/expr.test:
+	* generic/tclCompile.c: fixed 'bad code length' error for 'expr +
+	{[incr]}' case, with new test case [Bug 3736] and seg fault on 'expr
+	+ {[error]}' (different cause) that was caused by a correct
+	optimization that didn't correctly track how it was modifying the
+	source string in the opt. The optimization was removed, which means
+	that:
+		expr 1 + {[string length abc]}
+	will be not be compiled inline as before, but this should be written:
+		expr {1 + [string length abc]}
+	which will be compiled inline for speed. This prevents:
+		expr 1 + {[mindless error]}
+	from seg faulting, and only affects optimizations for degenerate cases
+	[Bug 3737]
+
+1999-12-01  Scott Redman <redman@scriptics.com>
+
+	* generic/tcl.decls:
+	* generic/tclMain.c:
+	* unix/tclAppInit.c:
+	* win/tclAppInit.c: Added two new internal functions,
+	TclSetStartupScriptFileName() and TclGetStartupScriptFileName() and
+	added hooks into the main() code for supporting TclPro and other "big"
+	shells more easily without requiring a copy of the main() code.
+
+	* generic/tclEncoding.c:
+	* generic/tclEvent.c: Moved encoding-related startup code from
+	tclEvent.c into the more appropriate tclEncoding.c.
+
+1999-11-30  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclIO.c: fix from Kupries for	Tcl_UnstackChannel that
+	correctly handles resetting translation and encoding.
+
+	* generic/tclLoad.c: #def'd out the unloading of DLLs at finalize time
+	for Unix in TclFinalizeLoad. [Bug 2560 3373] Should be parametrized
+	to allow for user to specify unload or not.
+
+	* win/tclWinTime.c: fixed handling of %Z on NT for time zones that
+	don't have DST.
+
+1999-11-29  Jeff Hobbs  <hobbs@scriptics.com>

+	* tests/scan.test:
+	* generic/tclScan.c: fixed scan where %[..] didn't match anything and
+	added test case. [Bug 3700]
+
+1999-11-24  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* doc/open.n:
+	* win/tclWinSerial.c: adopted patch from Schroedter to handle
+	fconfigure $sock -lasterror on Windows. [RFE 3368]
+
+	* generic/tclCmdIL.c: made SORTMODE_INTEGER work with Longs [Bug 3652]
+
+1999-11-23  Scott Stanton  <stanton@scriptics.com>
+
+	* library/tcltest1.0/tcltest.tcl: Fixed bug where tcltest output went
+	to stdout instead of the specified output file in some cases.
+
+1999-11-19  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclProc.c: backed out change from 1999-11-18 as it could
+	affect return string from upvar as well.
+
+	* tools/tcl.wse.in: added tcltest1.0 library to distribution list
+
+	* doc/http.n:
+	* library/http2.1/http.tcl:
+	* library/http2.1/pkgIndex.tcl: updated http package to 2.2
+
+1999-11-18  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* unix/tcl.m4: added defined for _THREAD_SAFE in --enable-threads
+	case; added check for pthread_mutex_init in libc; in AIX case, with
+	--enable-threads ${CC}_r is used; fixed flags when using gcc on SCO
+
+	* generic/tclProc.c: corrected error reporting for default case at the
+	global level for uplevel command.
+
+	* generic/tclIOSock.c: changed int to size_t type for len in
+	TclSockMinimumBuffers.
+
+	* generic/tclCkalloc.c: fixed Tcl_DbCkfree to return a value on NULL
+	input. [Bug 3400]
+
+	* generic/tclStringObj.c: fixed support for passing in negative length
+	to Tcl_SetUnicodeObj, et al handling routines. [Bug 3380]
+
+	* doc/scan.n:
+	* tests/scan.test:
+	* generic/tclScan.c: finished support for inline scan by supporting
+	XPG identifiers.
+
+	* doc/http.n:
+	* library/http2.1/http.tcl: added register and unregister commands to
+	http:: package (better support for tls/SSL), as well as -type argument
+	to http::geturl. [RFE 2617]
+
+	* generic/tclBasic.c: removed extra decr of numLevels in Tcl_EvalObjEx
+	that could cause seg fault. (mjansen@wendt.de)
+
+	* generic/tclEvent.c: fixed possible lack of MutexUnlock in
+	Tcl_DeleteExitHandler. [Bug 3545]
+
+	* unix/tcl.m4: Added better pthreads library check and inclusion of
+	_THREAD_SAFE in --enable-threads case
+	Added support for gcc config on SCO
+
+	* doc/glob.n: added note about ..../ glob behavior on Win9*
+	* doc/tcltest.n: fixed minor example errors. [Bug 3551]
+
+1999-11-17 Brent Welch <welch@scriptics.com>
+
+	* library/http2.1/http.tcl: Correctly fixed the -timeout problem
+	mentioned in the 10-29 change. Also added error handling for failed
+	writes on the socket during the protocol.
+
+1999-11-09  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* doc/open.n: corrected docs for 'a' open mode.
+
+	* generic/tclIOUtil.c: changed Tcl_Alloc to ckalloc
+
+	* generic/tclInt.h:
+	* generic/tclObj.c: rolled back changes from 1999-10-29
+	Purify noted new leaks with that code
+
+	* generic/tclParse.c: added code in Tcl_ParseBraces to test for
+	possible unbalanced open brace in a comment
+
+	* library/init.tcl: removed the installed binary directory from the
+	auto_path variable
+
+	* tools/tcl.wse.in: updated to 8.3a1, fixed install of twind.tcl and
+	koi8-r.enc files
+
+	* unix/tcl.m4: added recognition of pthreads library for AIX
+
+1999-10-29  Brent Welch <welch@scriptics.com>
+
+	* generic/tclInt.h: Modified the TclNewObj and TclDecrRefCount in two
+	ways. First, in the case of TCL_THREADS, we do not use the special
+	Tcl_Obj allocator because that is a source of lock contention. Second,
+	general code cleanup to eliminate duplicated code. In particular,
+	TclDecrRefCount now uses TclFreeObj instead of duplicating that code,
+	so it is now identical to Tcl_DecrRefCount.

+	terminate. Without these changes, the test suite hangs on WinNT with 2
+	CPUs and threads enabled. Open issue, seems to be a sporadic hang on
+	dual CPU systems still (very rare).
+
+1999-07-26  Jennifer Hom  <jenn@scriptics.com>
+
+	* tests/tcltest.test:
+	* library/tcltest1.0/tcltest.tcl:
+	* doc/tcltest.n: Cleaned up code in ::tcltest::PrintError, revised
+	documentation, and added tests for the tcltest package.
+
+1999-07-23  Scott Redman  <redman@scriptics.com>
+
+	* tests/info.test:
+	* generic/tclParse.c: Removed patch for info command, breaks test
+	cases on Unix. Patch was bad and needs to be redone properly. [Bug
+	2382]
+
+1999-07-22  Scott Redman  <redman@scriptics.com>
+
+	* Changed version to 8.2b2.
+
+	* win/tclWinSock.c: Fixed hang with threads enabled, fixed semaphores
+	with threads disabled.
+
+	* win/safe.test: Fixed safe-6.3 with threads enabled.
+
+	* win/Makefile.in: Fixed calling of tcltest to fix safe.test failures
+	due to path TCL_LIBRARY path.
+
+	* win/tclWinPort.h: Block out include of sys/*.h in order to build
+	extensions with MetroWerks compiler for Win32. [Bug 2385]
+
+	* generic/tclCmdMZ.c:
+	* generic/tclIO.c: Fix ANSI-style prototypes based on patch from
+	Ulrich Ring. [Bug 2391]
+
+	* unix/Makefile.in: Need to make install-sh executable before calling
+	(with chmod +x). [Bug 2413]
+
+	* tests/var.test:
+	* generic/tclVar.c: Fixed bug that caused a seg. fault when using
+	"array set a(b) {}", which is a bad array name anyway. Now the "array
+	set" command will return an error in this case. Added test case and
+	fixed existing test. [Bug 2427]
+
+1999-07-21  Scott Redman  <redman@scriptics.com>
+
+	* tests/info.test:
+	* generic/tclParse.c: Applied patch to fix "info complete" for the
+	string {[a [b]}. Patch from Peter Spjuth. [Bug 2382]
+
+	* doc/Utf.3:
+	* generic/tcl.decls:
+	* generic/tclDecls.h:
+	* generic/tclUtf.c: Changed function declarations in
+	non-platform-specific public APIs to use "unsigned long" instead of
+	"size_t", which may not be defined on certain compilers (rather than
+	include sys/types.h, which may not exist).
+
+	* unix/Makefile.in: Added the Windows configure script to the
+	distribution file list, already shipping configure.in and the .m4
+	files, but needed the configure script itself.
+
+	* win/makefile.vc: Changed version number of DDE package in VC++
+	makefile to use 1.1 instead of 1.0.
+
+	* doc/open.n: Added documentation of \\.\comX notation for opening
+	serial ports on Windows (alternative to comX:).
+
+	* tests/ioCmd.test:
+	* doc/open.n:
+	* win/tclWinSerial.c: Applied patch from Rolf Schroedter to add
+	-pollinterval option to fconfigure to modify the maxblocktime used in
+	the fileevent polling. Added documentation and fixed the test case as
+	well.
+
+	* win/tclWinSock.c: Modified 8.1.0 version of the Win32 socket driver
+	to move the handling of the socket event window in a separate thread.
+	It also turned out that Win95 & Win98 were, in some cases, getting
+	multiple FD_ACCEPTs but only handling one. Added a count for the
+	FD_ACCEPT to take care of this. Tested on NT4 SP3, NT4 SP4, Win95, and
+	Win98. [Bug 2178 2256 2259 2329 2323 2355]
+
+1999-07-21  Jerry Peek  <jpeek@scriptics.com>
+
+	* README: Small tweaks to clean up typos and wording.
+
+1999-07-20  Melissa Hirschl  <hershey@matisse.scriptics.com>
+
+	* generic/tclInitScript.h:
+	* unix/tclUnixInit.c: merged code with 8.0.5. We now use an
+	intermediate global tcl var "tclDefaultLibrary" to keep the
+	"tcl_library" var from being set by the default value in the Makefile.
+	Also fixed a bug in which caused the value of TCL_LIBRARY env var to
+	be ignored.
+	* unix/tclWinInit.c: just updated some comments.
+
+1999-07-19  Melissa Hirschl  <hershey@matisse.scriptics.com>
+
+	* library/http2.1/http.tcl: updated -useragent text to say version

+
+	* generic/tcl.decls:
+	* generic/tclDecls.h:
+	* generic/tclStubInit.c: Add Tcl_SetNotifier to stub table. [Bug 2364]
+
+	* unix/aclocal.m4:
+	* unix/tcl.m4: Add check for Alpha/Linux to correct the IEEE floating
+	flag to the compiler, should be -mieee. Patch from Don Porter.
+

+	.HPJ file.
+
+1999-07-15  Scott Redman  <redman@scriptics.com>
+
+	* tools/tcl.wse.in: Fixed naming of target files for Windows.
+
+1999-07-14  Jerry Peek  <jpeek@scriptics.com>

+
+1999-07-12  Jerry Peek  <jpeek@scriptics.com>
+
+	* doc/re_syntax.n: Removed two notes to myself (oops), cleaned up
+	wording, fixed changebars, made two examples easier to read.
+
+1999-07-11  Scott Redman  <redman@scriptics.com>
+
+	* win/makefile.vc: Since the makefile.vc should continue to work while
+	we're working out bugs/issues in the new TEA-style
+	autoconf/configure/gmake build mechanism for Windows, the version
+	numbers of the Tcl libraries need to remain in sync. Modified the
+	version numbers in the makefile to reflect the change to 8.2b1.
+
+1999-07-09  Scott Redman  <redman@scriptics.com>
+
+	* win/configure.in: Eval DLLSUFFIX, LIBSUFFIX, and EXESUFFIX in the
+	configure script so that substitutions get expanded before being
+	placed in the Makefile. The "d" portion for debug libraries and DLLs
+	was not being set properly.
+
+1999-07-08  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/string.test:
+	* generic/tclCmdMZ.c: Fixed bug in string range bounds checking code.

+	* library/tcltest1.0/tcltest.tcl: Removed -asidefromdir and
+	-relateddir flags, removed unused ::tcltest::dotests proc, cleaned up
+	implementation of core file checking, and fixed the code that checks
+	for 1-letter flag abbreviations.
+
+1999-07-08  Scott Stanton  <stanton@scriptics.com>
+
+	* win/Makefile.in: Added tcltest target so runtest works properly.
+	Added missing names to the clean/distclean targets.
+
+	* tests/reg.test:
+	* generic/rege_dfa.c: Applied fix supplied by Henry Spencer for bug in
+	DFA state caching under lookahead conditions. [Bug 2318]
+
+1999-07-07  Scott Stanton  <stanton@scriptics.com>
+
+	* doc/fconfigure.n: Clarified default buffering behavior for the
+	standard channels. [Bug 2335]
+
+1999-07-06  Scott Redman  <redman@scriptics.com>
+
+	* win/tclWinSerial.c: New implementation of serial port driver from
+	Rolf Shroedter (Rolf.Schroedter@dlr.de) that allows more than one byte
+	to be read from the port. Implemented using polling instead of
+	threads, there is a max. 10ms latency between checking the port for
+	file events. [Bug 1980 2217]
+
+1999-07-06  Brent Welch  <welch@scriptics.com>
+
+	* library/http2.0/http.tcl: Fixed the -timeout option so it handles
+	timeouts that occur during connection attempts to hosts that are down
+	(the only case that really matters!)
+
+1999-07-03  Brent Welch  <welch@scriptics.com>
+
+	* doc/ChnlStack.3:
+	* generic/tcl.decls:
+	* generic/tclIO.c: Added a new variant of the "Trf patch" from Andreas
+	Kupres that adds new C APIs Tcl_StackChannel, Tcl_UnstackChannel, and
+	Tcl_GetStackedChannel.

+1999-07-03  Brent Welch  <welch@scriptics.com>
+
+	* generic/tclNotify.c:
+	* unix/tclUnixNotfy.c:
+	* unix/tclXtTest.c:
+	* unix/tclXtNotify.c:
+	* win/tclWinNotify.c:
+	* mac/tclMacNotify.c: Added Tcl_SetNotifier and the associated hook
+	points in the notifiers to be able to replace the notifier calls at
+	runtime. The Xt notifier and test program use this hook.
+
+1999-07-03  Brent Welch  <welch@scriptics.com>
+
+	* generic/tclParse.c: Changed parsing of variable names to allow empty
+	array names. Now "$(foo)" is a variable reference! Previous you had to
+	use something like $::(foo), which is slower. This change is requested
+	by Jean-Luc Fontaine for his STOOOP package.
+
+1999-07-01  Scott Redman  <redman@scriptics.com>
+
+	* generic/tclCmdAH.c:
+	* generic/tclFCmd.c: Call TclStat instead of TclpStat in order to
+	allow Tcl_Stat hooks to work properly.
+
+1999-06-29  Jennifer Hom  <jenn@scriptics.com>
+
+	* library/tcltest1.0/pkgIndex.tcl:
+	* library/tcltest1.0/tcltest.tcl:
+	* doc/tcltest.n:
+	* tests/all.tcl: Added -preservecore, -limitconstraints, -help, -file,
+	-notfile, -relateddir and -asidefromdir flags to the tcltest package
+	along with exported proc ::tcltest::getMatchingFiles. The
+	documentation was modified to match and all.tcl was modified to use
+	the new functionality instead of implementing -file itself.
+
+1999-06-28  Scott Redman  <redman@scriptics.com>
+
+	* generic/tclIndexObj.c:
+	* doc/GetIndex.3:
+	* tests/binary.test:
+	* tests/winDde.test: Applied patch from Peter Hardie (with changes) to
+	fix problem with Tcl_GetIndexFromObj() when the key being passed is
+	the empty string. It used to match "" and return TCL_OK, but it should
+	have returned TCL_ERROR instead. Added test case to "binary" and "dde"
+	commands to check the behavior. Added documentation note as well.
+
+1999-06-26  Scott Redman  <redman@scriptics.com>
+
+	* win/tclWinDde.c: Applied patch from Peter Hardie to add poke command
+	to dde. Also rev'd version of dde package to 1.1. [Bug 1738]
+
+1999-06-25  Jennifer Hom  <jenn@scriptics.com>
+
+	* unix/Makefile.in:
+	* win/Makefile.in:
+	* library/tcltest1.0/pkgIndex.tcl:
+	* library/tcltest1.0/tcltest.tcl:
+	* library/tcltest1.0: Added initial implementation of the Tcl test
+	harness package. This package was based on the defs.tcl file that was
+	part of the tests directory. Reversed the way that tests were
+	evaluated to fix a problem with false passes.
+
+	* doc/tcltest.n: Added documentation for the tcltest package.
+
+	* tests/README:
+	* tests/defs.tcl:
+	* tests/all.tcl: Modified all test files (tests/*.test) and all.tcl to
+	use the new tcltest package and removed references to the defs.tcl
+	file. Modified the README file to point to the man page for tcltest.
+
+1999-06-25  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/reg.test:
+	* generic/regexec.c: Fixed bugs in non-greedy quantifiers.

+	* doc/RegExp.3:
+	* doc/regexp.n:
+	* doc/regsub.n: Moved information about syntax of 8.1 regular
+	expressions from regexp(n) manpage into new re_syntax(n) page. Added
+	pointers from other manpages to new re_syntax(n) page.

+	definitions of character classes.
+
+1999-06-21  Scott Stanton  <stanton@scriptics.com>
+
+	* unix/tclUnixThrd.c (TclpThreadCreate): Fixed memory leak where
+	thread attributes were not being released. [Bug 2254]

+1999-06-17  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/regexp.test:

+	compile/execute flags.
+
+	* generic/tclTest.c:
+	* generic/tclRegexp.h:
+	* generic/tclRegexp.c:
+	* generic/tcl.h:
+	* generic/tcl.decls: Renamed Tcl_RegExpMatchObj to Tcl_RegExpExecObj
+	and added a new Tcl_RegExpMatchObj that is equivalent to
+	Tcl_RegExpMatch. Added public macros for the regexp compile/execute
+	flags. Changed to store either an object pointer or a string pointer
+	in the TclRegexp structure. Changed to avoid adding a reference to the
+	object or copying the string.
+
+	* generic/regcomp.c: lint
+
+	* tests/reg.test:
+	* generic/regex.h:
+	* generic/regc_lex.c: Added REG_BOSONLY flag to allow Expect to

+
+1999-06-16  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/execute.test:
+	* generic/tclExecute.c (TclExecuteByteCode): Fixed crash caused by a
+	bug in INST_LOAD_SCALAR1 where the scalar index was read as a signed 1
+	byte value instead of unsigned. [Bug 2243]
+
+1999-06-14  Melissa Hirschl  <hershey@matisse.scriptics.com>

+	* doc/StringObj.3
+	* test/stringObj.test
+	* unix/Makefile.in
+	* win/Makefile.in

+	Tcl_AppendUnicodeToObj.
+
+1999-06-09  Scott Stanton  <stanton@scriptics.com>

+	* generic/tcl.decls: Added Tcl_RegExpMatchObj and Tcl_RegExpGetInfo
+	calls to access lower level regexp API. These features are needed by
+	Expect. This is a preliminary implementation pending final review and
+	cleanup.
+
+	* generic/tclCmdMZ.c:
+	* tests/string.test: Fixed bug where string map failed on null strings
+
+	* generic/regexec.c:
+	* unix/tclUnixNotfy.c: lint
+
+	* tools/genStubs.tcl: Changed to always write output in LF mode.
+
+1999-06-08  Scott Stanton  <stanton@scriptics.com>
+
+	* win/tclWinSock.c: Rolled back to the 8.1.0 implementation because of
+	serious problems with the new driver. Basically no incoming socket
+	connections would be reported to a server port. The 8.1.1 code needs
+	to be redesigned and fixed correctly.
+
+1999-06-07  Melissa Hirschl  <hershey@matisse.scriptics.com>
+

+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): optimized the string index,
+	string length, string range, and append command in cases where the

+	* win/Makefile.vc:
+	* tests/unicode.test:
+	* generic/tclInt.h:

+	* generic/tclUnicodeObj.c: added a new object type to store the
+	unicode representation of a string.
+
+	* generic/tclTestObj.c: added the objtype option to the testobj
+	command. This option returns the name of the type of internal rep an
+	object has.
+
+1999-06-04  Scott Stanton  <stanton@scriptics.com>
+
+	* win/configure.in:
+	* win/Makefile.in: Windows build now handles static/dynamic

+
+	* win/Makefile.in:
+	* win/configure.in: Added preliminary TEA implementation.
+
+	* win/tclWinDde.c: Fixed bug where dde calls were being passed an

+1999-05-26  Scott Redman  <redman@scriptic.com>
+
+	* generic/tclThreadTest.c: Fixed race condition in testthread code
+	that showed up in the WinNT test suite intermittently.
+
+	* win/tclWinSock.c: Fixed a hang in the WinNT socket driver, wake up

+	did not wake up the thread (race condition).
+
+1999-05-24  Scott Stanton  <stanton@scriptics.com>

+
+1999-05-21  Scott Redman  <redman@scriptics.com>
+
+	* win/tclWinPipe.c: Fix bug when launching command.com on Win95/98.
+	Need to wait for the procInfo.hProcess of the process that was
+	created, not the hProcess of the current process. [Bug 2105]
+
+1999-05-20  Scott Redman  <redman@scriptics.com>
+
+	* library/init.tcl: Add the directory where the executable is, and the

+
+1999-05-19  Scott Stanton  <stanton@scriptics.com>
+
+	Merged in various changes submitted by Jeff Hobbs:

+	support case-insensitive globbing.
+
+	* doc/string.n:
+	* unix/mkLinks:
+	* tests/string.test:
+	* generic/tclCmdMZ.c: Added additional character class tests, added
+	-nocase switch to "string match", changed string first/last to use
+	offsets.
+
+1999-05-19  Scott Redman  <redman@scriptics.com>
+
+	* generic/tcl.h: Add extern "C" block around entire header file for
+	C++ compilers to fix linkage issues. Submitted by Don Porter and Paul
+	Duffin.
+
+	* generic/tclRegexp.c: Fix bug when the regexp cache is empty and an
+	empty pattern is used in regexp ( such as {} or "" ).
+
+1999-05-18  Scott Stanton  <stanton@scriptics.com>
+
+	* win/tclWinChan.c: Modified initialization code to avoid inherenting
+	closed or invalid channels. If the standard input is anything other
+	than a console, file, serial port, or pipe, then we fall back to the
+	standard Tk window console.
+
+1999-05-14  Scott Stanton  <stanton@scriptics.com>
+
+	* generic/tclCmdAH.c (Tcl_ForObjCmd): Fixed crash caused by failure to
+	reset the result before evaluating the test expression.
+
+1999-05-14  Bryan Surles  <surles@scriptics.com>
+
+	* generic/tclBasic.c (Tcl_CreateInterp): Added introspection variable

+
+	* unix/Makefile.in:
+	* unix/tclAppInit.c: Minor cleanup related to Xt notifier.
+
+	* unix/tclUnixInit.c (TclpSetInitialEncodings): Tcl now looks for an
+	encoding subfield in the LANG/LC_ALL variables in cases where the
+	locale is not found in the locale table. Ensure that setlocale() is
+	called at least once so X11 will initialize properly. Also, forces the
+	LC_NUMERIC locale to be "C" so numeric processing in scripts is not
+	affected by the current locale setting. [Bug 1989]

+	* generic/tclRegexp.c: Increased per-thread regexp cache to 30 slots.
+	This seems to be about the right number for larger applications like
+	exmh. [Bug 1063]
+
+1999-05-12  Scott Stanton  <stanton@scriptics.com>
+
+	* doc/tclsh.1: Updated references to rc script names to accurately
+	reflect the platform differences on Windows.
+
+	* tests/regexp.test:
+	* generic/tclInt.h:
+	* generic/tclBasic.c:
+	* generic/tclRegexp.h:
+	* generic/tclRegexp.c: Replaced the per-interpreter regexp cache with
+	a per-thread cache. Changed the Regexp object to take advantage of
+	this extra cache. Added a reference count to the TclRegexp type so
+	regexps can be shared by multiple objects. Removed the per-interp
+	regexp cache from the interpreter. Now regexps can be used with no
+	need for an interpreter. [Bug 1063]
+
+	* win/tclWinInit.c (TclpSetVariables): Avoid calling GetUserName if
+	the value can be determined from the USERNAME environment variable.
+	GetUserName is very slow.
+
+1999-05-07  Scott Stanton  <stanton@scriptics.com>
+
+	* win/winDumpExts.c:
+	* win/makefile.vc: Removed incorrect patch. [Bug 1998]
+
+	* generic/tcl.decls: Replaced const with CONST.
+
+	* generic/tclResult.c (Tcl_AppendResultVA):
+	* generic/tclStringObj.c (Tcl_AppendStringsToObjVA): Fixed to copy
+	arglist using memcpy instead of assignment so it works properly on
+	OS/390. [Bug 1997]
+
+	* generic/tclLoadNone.c: Updated to use current interfaces, added
+	TclpUnloadFile. [Bug 2003]
+
+	* win/winDumpExts.c:
+	* win/makefile.vc: Changed to emit library name in defs file. [Bug
+	1998]
+
+	* unix/configure.in: Added fix for OS/390. [Bug 1976]
+
+1999-05-06  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/string.test:
+	* generic/tclCmdMZ.c:
+	* doc/string.n: Fixed bug in string equal/compare code when using
+	-length option. Cleaned up docs a bit more.
+
+	* tests/http.test: Unset "data" array before running tests to avoid
+	failures due to previous tests.
+

+	* tests/cmdIL.test:
+	* generic/tclUtil.c:
+	* generic/tclCmdMZ.c: Replaced "string icompare/iequal" with -nocase
+	and -length switches to "string compare/equal". Added a -nocase option
+	to "string map". Changed index syntax to allow integer or
+	end?-integer? instead of a full expression. This is much simpler with
+	safeTcl scripts since it avoids double substitution issues.
+
+	* doc/Utf.3:
+	* generic/tclStubInit.c:
+	* generic/tclDecls.h:
+	* generic/tclUtf.c:
+	* generic/tcl.decls: Added Tcl_UtfNcmp and Tcl_UtfNcasecmp.
+
+1999-05-05  Scott Stanton  <stanton@scriptics.com>
+

+
+1999-05-03  Scott Stanton  <stanton@scriptics.com>
+
+	* doc/string.n:
+	* tests/cmdMZ.test:
+	* tests/string.test:
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Changed "string length" to
+	avoid regenerating the string rep of a ByteArray object.
+
+	* tests/cmdIL.test:
+	* tests/cmdMZ.test:
+	* tests/error.test:
+	* tests/lindex.test:
+	* tests/linsert.test:
+	* tests/lrange.test:
+	* tests/lreplace.test:
+	* tests/string.test:
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd):
+	* generic/tclUtil.c (TclGetIntForIndex): Applied Jeff Hobbs's string
+	patch which includes the following changes [Bug 1845]:
+	- string compare now takes optional length arg (for strncmp behavior)
+	- added string equal (just a few lines of code blended in with string
+	  compare)
+	- added string icompare/iequal for case-insensitive comparisons
+	- string index's index can now be ?end[+-]?expression
+	  I made this change in the private TclGetIntForIndex, which means
+	  that the list commands also benefit, as well as string range, et al.
+	- added [string repeat string count]
+	  Repeats given string number of times
+	- added string replace, string equiv to lreplace
+	  (quasi opposite of string range):
+		string replace first last ?string?
+	  Example of use, replacing end of string with ... should the string
+	  be more than 16 chars long:
+		string replace $string 16 end "..."
+	  This just returns the string len < 16, so it will only affect the
+	  long strings.
+	- added optional first and last args to string to*
+	  This allows you to just affect certain regions of a string with the
+	  command (like just capping the first letter). I found the original
+	  totitle to be too draconian to be useful.
+	- added [string map charMap string]
+	  where charMap is a {from to from to} list that equates to what one
+	  might get from [array get]. Each and can be multiple chars (or none
+	  at all). For Tcl/CGI users, this is a MAJOR speed booster.
+
+	* generic/tclParse.c (Tcl_ParseCommand): Changed to avoid modifying
+	eval'ed strings that are already null terminated. [Bug 1793]
+
+	* tests/binary.test:
+	* generic/tclBinary.c (DupByteArrayInternalRep): Fixed bug where type
+	was not being set in duplicated object. [Bug 1975, 2047]
+
+1999-04-30  Scott Stanton  <stanton@scriptics.com>
+
+	* Changed version to 8.1.1.
+
+1999-04-30  Scott Stanton  <stanton@scriptics.com>
+
+	* Merged changes from 8.1.0 branch:
+
+	* generic/tclParse.c: Fixed memory leak in CommandComplete.
+
+	* generic/tclPlatDecls.h:
+	* generic/tclIntPlatDecls.h:
+	* generic/tclIntDecls.h:
+	* generic/tclDecls.h:
+	* tools/genStubs.tcl: Added 'extern "C" {}' block around the stub
+	table pointer declaration so the stub library can be used from C++.
+	[Bug 1934]
+
+	* Lots of documentation and other release engineering fixes.
+
+1999-04-28  Scott Stanton  <stanton@scriptics.com>
+
+	* mac/tclMacResource.c:
+	* generic/tclListObj.c:
+	* generic/tclObj.c:
+	* generic/tclStringObj.c: Changed to avoid freeing the string
+	representation before freeing the internal rep. This helps with
+	debugging since the string rep will still be valid when the free proc
+	is invoked.
+
+1999-04-27  Scott Stanton  <stanton@scriptics.com>
+
+	* generic/tclLiteral.c (TclHideLiteral): Fixed so hidden literals get
+	duplicated to avoid accidental sharing in the global object table.
+
+1999-04-23  Scott Stanton  <stanton@scriptics.com>
+
+	* generic/tclStubInit.c:
+	* tools/genStubs.tcl: Changed to avoid the need for forward
+	declarations in stub initializers.
+
+1999-04-23  Scott Stanton  <stanton@scriptics.com>
+
+	* library/encoding/koi8-r.enc:
+	* tools/encoding/koi8-r.txt: Added support for the koi8-r Cyrillic
+	encoding. [Bug 1771]
+
+1999-04-22  Scott Stanton  <stanton@scriptics.com>
+
+	* win/tclWinFCmd.c:
+	* win/tclWin32Dll.c: Changed uses of "try" to "__try", since that is
+	the actual keyword. This eliminates the need for some -D flags from
+	the makefile.
+
+	* generic/tclPort.h: Added include of tcl.h since it defines various
+	Windows macros that are needed before deciding which platform porting
+	file to use.
+
+	* generic/tclEvent.c: lint
+
+	* win/tclWinInit.c (TclpInitPlatform): Added call to TclWinInit when
+	building a static library since DllMain will not be invoked. This
+	could break old code that explicitly called TclWinInit, but should be
+	simpler in the long run.
+
+1999-04-22  Scott Stanton  <stanton@scriptics.com>
+
+	* generic/tclInt.h:
+	* generic/tclInt.decls:
+	* generic/tclCompile.c: Added TclSetByteCodeFromAny that takes a hook
+	procedure to invoke after compilation but before the byte codes are
+	emitted. This makes it possible to do postprocessing on the compiled
+	byte codes before the ByteCode is generated.
+
+	* generic/tclLiteral.c: Added TclHideLiteral and TclAddLiteralObj to
+	make it possible to create local unshared literal objects.
+
+	* win/tclWinInit.c:
+	* unix/tclUnixInit.c: Changed initial search path to match that
+	found used by tcl_findLibrary.
+
+1999-04-22  Scott Redman  <redman@scriptics.com>
+
+	* win/tclWinPort.h:
+	* win/tclWinSock.c: Added code to use WinSock 2.0 API on NT to avoid
+	creating a window to handle sockets. API not available on Win95 and
+	needs to be fixed on Win98, until then continue to use the older
+	(window-based) scheme on those two OSes.
+
+1999-04-15  Scott Stanton  <stanton@scriptics.com>
+
+	* Merged 8.1 back into the main trunk
+
+1999-04-13  Scott Stanton  <stanton@scriptics.com>
+
+	* library/encoding/gb2312.enc:
+	* library/encoding/euc-cn.enc:
+	* tools/encoding/gb2312.txt:
+	* tools/encoding/cp950.txt:
+	* tools/encoding/Makefile: Restored the double byte definition of
+	GB2312 and added the EUC-CN encoding. EUC-CN is a variant of GB2312
+	that shifts the characters into bytes with the high bit set and
+	includes ASCII as a subset. [Bug 632]
+
+1999-04-13  Scott Redman  <redman@scriptics.com>
+
+	* win/tclWinSock.c: Apply patch to allow write access to a socket if
+	FD_WRITE is sent but FD_CONNECT is not. Some strange problem with
+	either Win32 or a socket driver. [Bug 1664 1776]
+
+1999-04-09  Scott Redman  <redman@scriptics.com>
+
+	* unix/tclUnixNotfy.c: Fixed notifier deadlock situation when the pipe
+	used to talk back notifier thread is filled with data. When calling
+	the write() function to feed data down that pipe, unlock the
+	notifierMutex to allow the notifier to wake up again. Found as a
+	result of the focus.test for Tk hanging. [Bug 1700]
+
+1999-04-06  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/unixNotfy.test: Fixed hang in tests when built with thread
+	support.
+
+	* tests/httpold.test: Fixed broken test that didn't wait long enough
+	for events to arrive.
+
+	* tests/unixInit.test: Fixed race condition in test.
+
+	* tests/unixInit.test:
+	* tests/fileName.test: Minor test nits.
+
+	* unix/tclUnixInit.c (TclpSetInitialEncodings): Fixed bad initial
+	encoding string.
+
+1999-04-06  Bryan Surles  <surles@scriptics.com>
+
+	* generic/tclVar.c:
+	* generic/tclEnv.c: Moved the "array set" C level code into a common
+	routine (TclArraySet). The TclSetupEnv routine now uses this API to
+	create an env array w/ no elements.
+
+	* generic/tclEnv.c:
+	* generic/tclWinInit.h:
+	* generic/tclUnixInit.h:
+	* generic/tclInt.h: Made the Env module I18N compliant. Changed the
+	FindVariable routine to TclpFindVariable, that now does a case
+	insensitive string comparison on Windows, and not on UNIX. [Bug 1299,
+	1500]
+
+1999-04-05  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/io.test: Minor test cleanup.
+
+	* generic/tclEncoding.c (Tcl_CreateEncoding): Minor lint to make it
+	easier to compile on Digital-unix. [Bug 1659]
+
+	* unix/configure.in:
+	* unix/tclUnixPort.h: Applied patch for OS/390 to handle lack of
+	sys/param.h. [Bug 1725]
+
+	* unix/configure.in: Fixed BSD/OS 4.* configuration to support shared
+	libraries properly. [Bug 1730]
+
+1999-04-05  Scott Redman  <redman@scriptics.com>
+
+	* win/tclWinDde.c: decrease timeout value for DDE calls to 30k. [Bug

+	* generic/tclDecls.h:
+	* generic/tclInt.decls:
+	* generic/tclInt.h:
+	* generic/tclIntDecls.h:
+	* generic/tclStubInit.c:
+	* generic/tclUtil.c: Added more functions to the Tcl stubs table,
+	including all Tcl_ functions not already in it (except Cmd functions)
+	and Tcl_GetCwd() and Tcl_Chdir() (new functions).
+
+	* tests/safe.test:
+	* doc/safe.n:
+	* generic/tclBasic.c:
+	* library/safe.tcl: The encoding command is not safe as-is, so create
+	a safe alias to mask out the "encoding system <name>" but allow all
+	other uses including "encoding system". Added test cases and updated
+	the man page for Safe Tcl.
+
+1999-04-05  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/winTime.test:
+	* win/tclWinTime.c: Fixed crash in clock command that occurred when
+	manipulating negative time values in timezones east of GMT. [Bug
+	1142, 1458]
+
+	* tests/platform.test:
+	* tests/fileName.test: Fixed broken tests.
+
+	* generic/tclFileName.c: Moved global regexps into thread local
+	storage.
+
+	* tests/socket.test: Changed so tests don't reuse sockets, since
+	Windows is slow to release sockets.
+
+	* win/tclWinConsole.c:
+	* win/tclWinPipe.c:
+	* win/tclWinSerial.c: Fixed race condition where background threads
+	were terminated while they still held a lock in the notifier.
+
+1999-04-02  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/http.test: Fixed bad test initialization code.
+
+	* generic/tclThreadTest.c (ThreadExitProc): Fixed bug where static
+	memory was being returned instead of a dynamically allocated result in
+	error cases.
+
+1999-04-02  Scott Redman  <redman@scriptics.com>
+
+	* doc/dde.n:
+	* tools/tcl.wse.in:
+	* win/makefile.vc:
+	* win/pkgIndex.tcl:
+	* win/tclWinDde.c: Add new DDE package, code removed from Tk now
+	separated into its own package. Changed DDE-based send code into "dde
+	eval" command. Can be loaded into tclsh (not just wish). Windows only.

+
+1999-04-01  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/registry.test:
+	* win/tclWinReg.c: Internationalized the registry code. It now uses
+	Unicode interfaces on NT. [Bug 1197]
+
+	* tests/parse.test:
+	* generic/tclParse.c: Fixed crash due to multiple frees in parser
+	during error cleanup when parsing commands with more tokens than will
+	fit in the static area of the parse structure. [Bug 1681]
+
+	* generic/tclInt.h: Removed duplicate declarations.
+
+	* generic/tclInt.decls:
+	* generic/tcl.decls: Added Tcl_WinUtfToTChar and Tcl_WinTCharToUtf to

+	* unix/Makefile.in:
+	* win/makefile.vc: Applied patch from Jan Nijtmans to fix Ultrix
+	multiple symbol definition problem. Now, even Tcl includes a copy of
+	the Tcl stub library. Also fixed TCL_MEM_DEBUG mode (for Tk).
+
+1999-03-31  Scott Redman  <redman@scriptics.com>
+
+	* win/tclWinConsole.c: WinNT has a bug when reading a single character
+	from the console. Rewrote the code for the console to read an entire
+	line at a time using the reader thread.
+
+1999-03-30  Scott Stanton  <stanton@scriptics.com>
+
+	* unix/Makefile.in: Removed trailing backslash that broke the "depend"
+	target.
+
+	* unix/tclUnixInit.c (TclpSetInitialEncodings): Changed to avoid
+	calling setlocale(). We now look directly at env(LANG) and
+	env(LC_CTYPE) instead. [Bug 1636]
+
+	* generic/tclFileName.c:
+	* generic/tclDecls.h:
+	* generic/tcl.decls: Removed CONST from Tcl_JoinPath and
+	Tcl_TranslateFileName because it changes the signature of Tcl_JoinPath
+	in an incompatible manner.
+
+	* generic/tclInt.h:
+	* generic/tclLoad.c (TclFinalizeLoad):
+	* generic/tclEvent.c (Tcl_Finalize): Defer unloading of loadable

+	stubs on Solaris).
+
+1999-03-27  Scott Redman  <redman@scriptics.com>

+
+	* win/tclWinSerial.c:
+	* win/tclWinConsole.c:
+	* win/tclWinPipe.c: Don't close the Win32 handle for a channel if it's

+	it from destroying the stdio of other threads.
+
+1999-03-26  Suresh Ankolekar  <suresh@scriptics.com>
+
+	* unix/configure.in: --nameble-shared is now the default and build Tcl
+	as a shared library; specify --disable-shared to build a static Tcl
+	library and shell.
+
+1999-03-25  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/interp.test:
+	* generic/tclInterp.c (AliasObjCmd): Changed so aliases are invoked at
+	current scope in the target interpreter instead of at the global
+	scope. This was an incompatibility introduced in 8.1 that is being
+	removed. [Bug 1153, 1556]
+
+	* library/encoding/big5.enc:
+	* library/encoding/gb2312.enc:
+	* tools/encoding/big5.enc:
+	* tools/encoding/gb2312.enc: Added ASCII to big5 and gb2312 encodings.
+	[Bug 632]
+
+	* generic/tclPkg.c (Tcl_PkgRequireEx): Fixed broken clientData
+	initialization in package code.
+
+	* unix/Makefile.in (dist): Added tcl.decls and tclInt.decls to source
+	distribution. [Bug 1571]
+
+	* doc/Thread.3: Updated documentation of Tcl_MutexLock to indicate
+	that the recursive locking behavior is undefined. On Windows, it does
+	not block, on Unix it deadlocks. [Bug 1275]
+
+1999-03-24  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/execute.test:
+	* generic/tclExecute.c (TclExecuteByteCode): Fixed expression code
+	that incorrectly returned floating point values for integers if the
+	internal rep happened to be a double. Now we check to see if the
+	object has a string rep that looks like an integer before using the
+	double internal rep. [Bug 1516]
+
+1999-03-24  Scott Redman  <redman@scriptics.com>
+
+	* generic/tclAlloc.c:
+	* generic/tclEncoding.c:
+	* generic/tclProc.c:
+	* unix/tclUnixTime.c:
+	* win/tclWinSerial.c: Fixed compilation warnings/errors for VC++ 5.0
+	and 6.0 and HP-UX native compiler without -Aa or -Ae. [Bug 1323 1518
+	1324 1583 1585 1586]
+
+	* win/tclWinSock.c: Make sockets thread-safe on Windows. The current
+	implementation uses windows to handle events on the socket, one for
+	each thread (thread local storage). Previously, there was only one
+	window shared between threads, which didn't work. [Bug 1326]
+
+1999-03-23  Scott Stanton  <stanton@scriptics.com>
+
+	* tools/tcl.wse: Fixed file association to look in the right place for

+	* tests/winNotify.test:
+	* mac/tclMacNotify.c:
+	* win/tclWinNotify.c:
+	* unix/tclUnixNotfy.c:
+	* generic/tclNotify.c: Added a new Tcl_ServiceModeHook interface that
+	is invoked whenever the service mode changes. This is needed to allow
+	the Windows notifier to create a communication window the first time
+	Tcl is about to enter an external modal event loop instead of at
+	startup time. This will avoid the various problems that people have
+	been seeing where the system hangs when tclsh is running outside of
+	the event loop. [Bug 783]
+
+	* generic/tclInt.h:
+	* generic/tcl.decls: Renamed TclpAlertNotifier back to
+	Tcl_AlertNotifier since it is part of the public notifier driver API.
+
+1999-03-23  Scott Redman  <redman@scriptics.com>
+
+	* win/tclWinSerial.c: Fixed problem with fileevent on the serial port
+	and nonblocking mode. Gets no longer hangs, fileevents fire whenever
+	there is any character data on the port.
+
+	* tests/winConsole.test:
+	* win/tclWinConsole.c: Fixed problem with fileevents and gets from a
+	console stdin. Previously, fileevents were firing before an entire
+	line was available for reading, which meant that when you did a gets
+	or read, it blocked (even in nonblocking mode). Now, it should work
+	the same as Unix: fileevents fire when an entire line is ready, and
+	gets and read do not block in non-blocking mode. Added an interactive
+	test case to check for this.
+
+1999-03-22  Scott Stanton  <stanton@scriptics.com>
+
+	* tests/reg.test:
+	* generic/regc_color.c: Applied regexp bug fix from Henry Spencer.
+
+1999-03-19  Scott Redman  <redman@scriptics.com>
+
+	* generic/tclCmdIL.c: Fixed the initialization of an array so that the
+	Sun 5.0 C compiler wouldn't complain.
+
+	* unix/configure.in: Added support for --enable-64bit. For now, this
+	is only supported on Solaris 7 64bit (SunOS 5.7) using the Sun
+	compiler (not gcc).
+
+1999-03-18  Scott Stanton  <stanton@scriptics.com>
+
+	* win/tclWinChan.c (TclpOpenFileChannel, Tcl_MakeFileChannel): Changed
+	to only test for console or comm handles when the type is
+	FILE_TYPE_CHAR to avoid useless tests on simple files. Also reordered
+	tests so consoles are tested first as this is more common.
+
+	* win/makefile.vc: Regularized usage of mkd and rmd and rm.
+
+	* library/encoding/shiftjis.enc:
+	* tools/encoding/shiftjis.txt: Missing/incorrect characters in
+	shift-jis table. [Bug 1008, 1526]
+
+	* generic/tclInt.decls:
+	* generic/tcl.decls: Eliminated use of "string" and "list" from
+	argument lists to avoid conflicts with C++ STL. [Bug 1181]
+
+	* win/tclWinFile.c (TclpMatchFiles): Changed to ignore the
+	FS_CASE_IS_PRESERVED bit and always return exactly what we get from
+	the system.
+
+1999-03-17  Scott Stanton  <stanton@GASPODE>
+
+	* win/README.binary:
+	* win/README:

+
+	* win/tclWinConsole.c:
+	* win/tclWinPipe.c:
+	* win/tclWinSerial.c: Changed so channel drivers wait for the
+	reader/writer threads to exit before returning during a close
+	operation. This ensures that the main thread is the last thread to
+	exit, so the process return value is set properly.
+
+	* generic/tclIntDecls.h:

+	safe interps.
+
+1999-03-11  Scott Stanton  <stanton@GASPODE>
+

+	* unix/configure.in: Include compat files in the stub library in
+	addition to the main library. Compat files are now built for dynamic
+	use in all cases.

+
+1999-03-10  Scott Stanton  <stanton@GASPODE>
+
+	* generic/tcl.h:
+	* generic/tcl.decls: Changed Tcl_ReleaseType from an enum to macros so
+	it can be used in .rc files. Added Tcl_GetString.
+
+	* mac/tclMacNotify.c:
+	* generic/tclNotify.c:
+	* generic/tclInt.h:
+	* win/tclWinNotify.c:
+	* generic/tcl.h: Renamed Tcl_AlertNotifier to TclpAlertNotifier.

+
+	* mac/tclMacPort.h:
+	* win/tclWinInit.c:
+	* unix/tclUnixPort.h:
+	* generic/tclAsync.c: Added TclpAsyncMark to fix bug in async handling
+	on Windows where async events don't wake up the event loop. This patch
+	comes from Gordon Chaffee.
+
+	* generic/tcl.decls: Fixed declarations of reserved slots.
+
+1999-03-10  Scott Redman  <redman@scriptic.com>
+
+	* generic/tclCompile.h: Ensure that the ByteCode struct is binary
+	compatible with the version in 8.0.6.
+
+	* generic/tcl.h:
+	* generic/tclBasic.c: Add Tcl_GetVersion() function to the public C
+	API to allow programs to check the version number of the Tcl library
+	at runtime. Also added an enum to clarify the release level (alpha,
+	beta, final).
+
+1999-03-09  Scott Stanton  <stanton@GASPODE>
+
+	* Integrated changes from Tcl 8.0 including:
+		stubs mechanism

+		rename of panic to Tcl_Panic
+
+1999-03-08  Lee Bernhard  <lfb@scriptics.com>

+
+1999-03-08  Scott Stanton  <stanton@GASPODE>
+

+	* unix/configure.in:
+	* unix/Makefile.in:
+	* unix/tclConfig.sh.in:
+	* win/makefile.vc:
+	* win/tclWinPort.h: Added Tcl stubs implementation. There are now two
+	new macros USE_TCL_STUBS and USE_TCL_STUB_PROCS that enable use of
+	stubs and disable stub macros respectively. All of the public and
+	private function declarations from tcl.h and tclInt.h have moved into
+	the *.decls files and the *Stubs.c and *Decls.h files are generated
+	using the genStubs.tcl script.
+
+	* unix/Makefile.in:
+	* unix/configure.in:
+	* unix/ldAix: Enhanced AIX shared library support.
+
+	* win/tclWinSock.c: Removed a bunch of extraneous PASCAL FAR

+	they can be invoked from the stub functions.
+
+	* doc/package.n:
+	* doc/PkgRequire.3:
+	* generic/tclPkg.c: Added Tcl_PkgProvideEx, Tcl_RequireEx,
+	Tcl_PresentEx, and Tcl_PkgPresent. Added "package present" command.
+
+	* generic/tclFileName.c:
+	* mac/tclMacFile.c:
+	* mac/tclMacShLib.exp:
+	* unix/tclUnixFile.c:
+	* win/tclWinFile.c: Changed so TclGetUserHome is defined on all
+	platforms, even though it is currently a noop on mac and windows, and
+	renamed it to TclpGetUserHome.
+
+	* generic/tclPanic.c:
+	* generic/panic.c: Renamed panic to Tcl_Panic.
+
+1999-02-25  Scott Redman  <redman@scriptics.com>
+
+	* win/makefile.vc: Added tclWinConsole.c and tclWinSerial.c
+
+	* win/tclWinConsole.c: New code to properly deal with fileevents and
+	nonblocking mode on consoles.
+
+	* win/tclWinSerial.c: New code to properly deal with fileevents and
+	nonblocking mode on serial ports.
+
+	* win/tclWinPipe.c:
+	* win/tclWinPort.h: Exported functions to allow creation of pipe
+	channels from tclWinChan.c
+
+	* win/tclWinChan.c: Check the type of a channel, including for the
+	standard (stdin/stdout/stderr), and use the correct channel type to
+	create the channel (file, serial, console, or pipe).
+
+1999-02-11  Scott Stanton  <stanton@GASPODE>
+
+	* README:
+	* generic/tcl.h:
+	* win/README.binary:
+	* win/README:
+	* unix/configure.in:
+	* mac/README: Updated version numbers to 8.1b2.
+
+1999-02-10  Scott Stanton  <stanton@GASPODE>
+
+	* library/auto.tcl: Fixed auto_mkindex so it handles .tbc files. Did
+	some general cleanup to handle bad eval statements that didn't use
+	"list".
+
+	* unix/mkLinks:
+	* doc/SetVar.3:
+	* generic/tcl.h:
+	* generic/tclVar.c: Restored Tcl_ObjGetVar2 and Tcl_ObjSetVar2 from
+	8.0. Renamed Tcl_Get/SetObjVar2 to Tcl_GetVar2Ex and Tcl_SetVar2Ex.
+
+1999-02-10  Scott Stanton  <stanton@GASPODE>
+
+	INTEGRATED PATCHES FROM 8.0.5b2:
+
+	* test/winPipe.test: Changed to remove echoArgs.tcl temporary file
+	when done.
+
+	* tests/cmdAH.test:
+	* generic/tclFileName.c (TclGetExtension): Changed behavior so the
+	split happens at the last period in the name instead of the first
+	period of the last run of periods. So, "foo..o" is split into "foo."
+	and ".o" now. [Bug 1126]
+
+	* win/makefile.vc: Added better support for paths with spaces in the
+	name. Added .lib and support .dlls to the install-binaries target.
+	Added generate of a pkgIndex.tcl script to the install-libraries
+	target.
+
+	* win/tclAppInit.c:
+	* unix/tclAppInit.c:
+	* mac/tclMacAppInit.c:
+	* generic/tclTest.c: Changed some EXTERN declarations to extern since
+	they are not defining exported interfaces. This avoids generating
+	useless declspec() attributes and makes the windows makefile simpler.
+
+	* generic/tcl.h: Moved Tcl_AppInit declaration to end and cleared out
+	TCL_STORAGE_CLASS so it is not declared with a declspec().
+
+	* tests/interp.test:
+	* generic/tclInterp.c (DeleteAlias): Changed to use
+	Tcl_DeleteCommandFromToken so we handle renames properly. This avoids
+	senseless panic. [Bug 736]
+
+	* unix/tclUnixChan.c:
+	* win/tclWinSock.c:
+	* doc/socket.n: Applied Gordon Chaffee's patch to handle failures
+	during asynchronous socket connection operations. This adds a new
+	"-error" fconfgure option to socket channels. [Bug 893]
+
+	* generic/tclProc.c:
+	* generic/tclNamesp.c:
+	* generic/tclInt.h:
+	* generic/tclCmdIL.c:
+	* generic/tclBasic.c:
+	* generic/tclVar.c: Applied patch from Viktor Dukhovni to rationalize
+	TCL_LEAVE_ERR_MSG behavior when creating variables.
+
+	* generic/tclVar.c: Fixed bug in namespace tail computation. Fixed bug
+	where upvar could resurrect a namespace variable whose namespace had
+	been deleted.
+
+	* generic/tclCompile.c (TclCompileExprCmd): Eliminated yet another
+	bogus optimization in expression compilation.
+
+	* unix/configure.in: Added branch for BSD/OS-4* to shared library case
+	statement. [Bug 975]
+	Fixed to correctly handle IRIX 6.5 n32 library support. [Bug 1117]
+
+	* win/winDumpExts.c: Patched to be pickier about stripping @'s. [Bug
+	920]
+
+	* library/http2.0/http.tcl: Added catch around eof test in CopyDone
+	since the user may have already called http::reset. [Bug 1108]
+
+	* unix/configure.in: Changed Linux and IRIX to set SHLIB_LIBS to LIBS
+	so shared libraries are linked with the system libraries. [Bug 1018]
+
+	* generic/tclCompile.c (CompileExprWord): Fixed exception stack
+	overflow bug caused by missing statement. [Bug 928]
+
+	* generic/tclIOCmd.c:
+	* generic/tclBasic.c: Objectified the "open" command. [Bug 1113]
+
+	* generic/tclPosixStr.c (Tcl_ErrnoId, Tcl_ErrnoMsg): When using egcs,
+	ENOTSUP and EOPNOTSUPP are the same, so now we handle that case. [Bug
+	1137]
+
+	* library/init.tcl: Various small changes requested by Jan Nijtmans.
+	- If the variable $tcl_library contains the empty string, this empty
+	  string will be put in $auto_path. This is not useful at all, it only
+	  slows down later package processing.
+	- If the variable tcl_pkgPath is not set, the "unset __dir" fails.
+	  Thich makes init.tcl totally unusable. Better put a "catch" around
+	  it.
+	- In the function tcl_findLibraries, the "string match" function only
+	  works correctly if $tcl_patchLevel is in one of the forms "?.?a?",
+	  "?.?b?" or "?.?.?". Could a "regexp" be used instead, then it allows
+	  anything to be appended to the patchLevel string. And it is more
+	  efficient.
+	- The tclPkgSetup function assumes that if $type != "load" then the
+	  type must be "source". This needn't be true. Some users want to add
+	  their own setup types.
+	[RFE 1138] [Bug 978]
+
+	* win/tclWinReg.c:
+	* doc/registry.n: Added support for HKEY_PERFORMANCE_DATA and
+	HKEY_DYN_DATA keys. [Bug 1109]
+
+	* win/tclWinInit.c (TclPlatformInit): Added code to ensure tcl_pkgPath
+	is set to "" when no registry entry is found. [Bug 978]
+
+1999-02-01  Scott Stanton  <stanton@GASPODE>
+
+	* generic/tclBasic.c:

+	* generic/tclParse.c:
+	* generic/tclProc.c:
+	* generic/tclTest.c:
+	* generic/tclTimer.c:
+	* generic/tcl.h: Made eval interfaces compatible with 8.0 by renaming
+	Tcl_EvalObj to Tcl_EvalObjEx, renaming Tcl_Eval2 to Tcl_EvalEx and
+	restoring Tcl_EvalObj and Tcl_GlobalEvalObj interfaces so they match
+	Tcl 8.0.
+
+1999-01-28  Scott Stanton  <stanton@GASPODE>
+
+	* Merged Tcl 8.0.5b1 changes.
+
+	* generic/tclUtil.c (Tcl_DStringSetLength): Changed so the buffer
+	overallocates in a manner similar to Tcl_DStringAppend. This should
+	improve performance for TclUniCharToUtfDString.
+
+1998-12-11    === Tcl 8.1b1 Release ===
+
+1998-12-10  Scott Stanton  <stanton@GASPODE>
+
+	* Fixed lots of files that used TCL_THREAD instead of TCL_THREADS.
+
+	* generic/tclEncoding.c (Tcl_FreeEncoding): Moved most of the code
+	into a static FreeEncoding routine that does not grab the
+	encodingMutex to avoid deadlocks/races when called from other routines
+	that already have the mutex.
+
+1998-12-09  Scott Stanton  <stanton@GASPODE>
+
+	* library/msgcat1.0/msgcat.tcl: Fixed bad export list, fixed so all
+	locale strings are converted to lower case, including file names.
+
+	* generic/regcomp.c (makescan): Fixed bug in longest match case that
+	caused anchored patterns to fail. [Bug 897]
+
+1998-12-08  Scott Stanton  <stanton@GASPODE>
+
+	* library/msgcat1.0/msgcat.tcl: changed mc to invoke mcunknown in the
+	calling context, changed locale lookups to be case insensitive
+
+1998-12-07  Scott Stanton  <stanton@GASPODE>
+
+	* generic/tclAlloc.c (TclpRealloc): Fixed a memory allocation bug
+	where big blocks that were reallocated into a different heap location
+	were not being placed into the bigBlocks list. [Bug 933]
+
+	* tests/msgcat.test: Added message catalog test suite.
+
+	* library/msgcat1.0/msgcat.tcl: minor bug fixes, integrated latest
+	changes from Mark Harrison.
+
+1998-12-04  Scott Stanton  <stanton@GASPODE>
+
+	* library/msgcat1.0/msgcat.tcl: Changed code to conform to Tcl coding
+	standards. Changed to use file join for portability.
+
+	* library/msgcat1.0: Added initial implementaion of Tcl message
+	catalog package contributed by Mark Harrison.
+
+1998-12-03  Scott Stanton  <stanton@GASPODE>
+
+	* win/tclWinPipe.c (BuildCommandLine): Fixed bug that kept arguments
+	containing spaces from being properly quoted.
+
+	* tests/defs: Changed so auto_path is set to only contain the Tcl
+	library directory. This keeps the tests from accidentally picking up
+	stuff in installed packages.
+
+	* generic/tclUtil.c (Tcl_StringMatch): Changed to match 8.0 behavior
+	in corner case where there is no closing bracket.
+
+1998-12-02  Scott Stanton  <stanton@GASPODE>
+
+	* win/tclWinPipe.c (TclpCreateCommandChannel): Changed reader/writer
+	threads to have THREAD_PRIORITY_HIGHEST so they will have a chance to
+	run whenever there is something to do.
+
+	* generic/tclIO.c (WriteBytes, WriteChars): Fixed so extraneous
+	flushes do not happen in line mode.
+	(TranslateOutputEOL): Made translation more efficient in line mode and
+	fixed a buffer overflow bug in CRLF translation. [Bug 887]
+
+1998-12-02  Brent Welch  <welch@SAGE>
+
+	* Updated patchlevel to 8.1b1
+
+1998-12-02  Scott Stanton  <stanton@GASPODE>
+
+	* generic/regc_color.c (subcolor): Added check for error case to avoid
+	an out of bounds array reference.
+
+	* generic/tclCmdAH.c (Tcl_EncodingObjCmd): Changed to avoid using
+	Tcl_DStringResult because it is not binary clean.
+
+	* generic/tclParse.c (Tcl_ParseCommand): Fixed bug in comment parsing
+	where a trailing comment looked like an incomplete command.
+
+1998-12-02  Brent Welch  <welch@SAGE>
+
+	* Merged changes from 8.0.4, especially the new pkg_mkIndex
+
+1998-12-01  Scott Stanton  <stanton@GASPODE>
+
+	* generic/tclIO.c (Tcl_ReadChars): Added a call to UpdateInterest so
+	we don't block when there is data sitting in the buffers.
+
+	* generic/tclTest.c (TestevalobjvObjCmd): Updated for EvalObjv change.
+
+	* tests/parse.test: Updated tests for EvalObjv change.
+
+	* generic/tclParse.c (EvalObjv, Tcl_EvalObjv): Changed Tcl_EvalObjv
+	interface to remove string and length arguments, preserved original
+	interface as EvalObjv for internal use.
+
+	* generic/tcl.h: Changed Tcl_EvalObjv interface to remove string and
+	length arguments.
+
+	* doc/Eval.3: Updated documentation for Tcl_EvalObjv to remove string
+	and length arguments.
+
+	* generic/tclCompCmds.c (TclCompileForeachCmd): Fixed code that
+	corrupted the exceptDepth value in the compile environment when
+	foreach failed to compile inline. [Bug 884]
+
+	* library/encoding/euc-kr.enc:
+	* library/encoding/ksc5601.enc:
+	* tools/encoding/ksc5601.txt:
+	* unix/tclUnixInit.c: Added support for Korean EUC.
+
+	* win/tclWinChan.c (TclpGetDefaultStdChannel): added check for a
+	failure during Tcl_MakeFileChannel.
+
+1998-11-30  Scott Stanton  <stanton@GASPODE>
+
+	* unix/tclUnixNotfy.c (Tcl_WaitForEvent): Fixed hang that occurs when
+	trying to close a pipe that is currently being waited on by the
+	notifier thread. [Bug 607]
+
+	* unix/tclUnixFCmd.c (GetPermissionsAttribute): Increase size of
+	returnString buffer to avoid overflow. [Bug 584]
+
+	* generic/tclThreadTest.c (TclThreadSend): Fixed memory leak due to
+	use of TCL_VOLATILE instead of TCL_DYNAMIC.
+
+	* generic/tclThread.c (TclRememberSyncObject): Fixed memory leak
+	caused by failure to reuse condition variables.
+
+	* unix/tclUnixNotfy.c (Tcl_AlertNotifier, Tcl_WaitForEvent,
+	(NotifierThreadProc, Tcl_InitNotifier): Fixed race condition caused by
+	incorrect use of condition variables when sending messages between
+	threads. [Bug 607]
+
+	* generic/tclTestObj.c (TeststringobjCmd): MAX_STRINGS was off by one
+	so the strings array was too small.
+
+	* generic/tclCkalloc.c (Tcl_DbCkfree): Moved mutex lock so
+	ValidateMemory is done inside the mutex to avoid a race condition when
+	validate_memory is enabled. [Bug 880]
+
+1998-11-23  Scott Stanton  <stanton@GASPODE>
+
+	* regexec.c: more performance tuning from Henry Spencer.
+
+1998-11-17  Scott Stanton  <stanton@GASPODE>
+
+	* tclScan.c: moved "scan" implementation out of tclCmdMZ.c and added
+	Unicode support. This required a complete reimplementation of the
+	command to avoid using scanf(), which isn't Unicode aware. Two new
+	features were added in the process: %n to return the current number of
+	characters consumed, and XPG3-style %n$ argument order specifiers
+	similar to those provided by the "format" command. [Bug 833]
+
+	* tclAlloc.c: changed so allocated memory is always 8-byte aligned to
+	improve memory performance and to ensure that it will work on systems
+	that don't like accessing 4-byte aligned values (e.g. Solaris and
+	HP-UX). [Bug 834]
+
+1998-11-06  Scott Stanton  <stanton@GASPODE>
+
+	* tclVar.c (TclGetIndexedScalar): Fixed bug 796, var name was getting
+	lost before being passed to CallTraces.
+
+1998-10-21  Scott Stanton  <stanton@GASPODE>
+
+	* added "encoding" command
+
+	* Moved internal regexp declarations from tclInt.h to tclRegexp.h
+
+	* integrated regexp updates from Henry Spencer
+
+1998-10-15  Scott Stanton  <stanton@GASPODE>
+
+	* tclUtf.c: added Unicode character table support
+
+	* tclInt.h: added TclUniCharIsWordChar
+
+	* tclCmdMZ.c (Tcl_StringObjCmd): added "totitle" subcommand, changed
+	"wordend" and "wordstart" to properly handle Unicode word characters
+	and connector punctuation
+
+1998-10-05  Scott Stanton  <stanton@GASPODE>
+
+	* auto.tcl, package.tcl: fixed SCCS strings
+
+	* tclIndex: updated index to reflect 8.1 files
+
+	* tclCompile.c (TclCompileScript): changed to avoid modifying the
+	input string in place because name lookup operations could have
+	arbitrary side effects
+
+	* tclInterp.c: added guard against deleting current interpreter
+
+	* tclMacFile.c, tclUnixFile.c, tclWinFile.c, tclFileName.c: added
+	warnings around code that modifies strings in place
+

+
+	* generic/tclExecute.c:
+	* tests/expr-old.test: Re-wrote Tcl's [expr rand()] and [expr
+	srand($seed)] implementations, fixing a range error on some 64-bit
+	platforms. Added tests that detect the bug. The rewrite changes the
+	seed -> sequence map on 64-bit platforms, only for seed >= 2^31, a
+	slight incompatibility. [Bug 121072, Patch 102781]
+
+2000-12-10  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/init.tcl:
+	* library/msgcat/msgcat.tcl:
+	* library/msgcat/pkgIndex.tcl:
+	* library/opt/optparse.tcl:
+	* library/opt/pkgIndex.tcl: Where [uplevel] is used in a proc to
+	evaluate a Tcl built-in command in the caller's context, the built-in
+	commands are now fully namespace-qualified. This prevents problems
+	when the caller context is in a namespace where the built-in command
+	name has been used by a command in the namespace. (For example,
+	[::ns::set] might be called instead of the intended [::set]). [Bug
+	119422, Patch 102545]
+
+2000-12-09  Jeff Hobbs  <jhobbs@interwoven.com>
+
+	* win/tclWinTime.c (CalibrationThread): added lint return value to
+	prevent compiler warning. [Bug 125005]
+
+	* docs/scan.n:
+	* tests/scan.test:
+	* generic/tclScan.c (Tcl_ScanObjCmd): changed %o and %x to use strtoul
+	instead of strtol to correctly preserve scan<>format conversion of
+	large integers. [Patch 102663, Bug 124600]
+
+	* generic/tclExecute.c (TclExecuteByteCode): Commited patch fixing
+	handling of {!<boolean>} in expressions. [Patch 102702]
+
+2000-12-08  Jeff Hobbs  <jhobbs@interwoven.com>
+
+	* library/init.tcl: Added support for PATHEXT variable in auto_execok,
+	recognizing the proper set of executable extensions on Windows. [Patch
+	102719]
+
+2000-12-08  Andreas Kupries  <a.kupries@westend.com>
+
+	* generic/tclEncoding.c (LoadTableEncoding): Changed dangerous code to
+	something less critical. This fixes [Bug 119417], part A without
+	affecting the speed when loading encodings.
+
+2000-12-08  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/open.n: Added xref to fconfigure and advice on the opening of
+	binary files. Should help prevent a recurrence of bugs like [Bug
+	124558]
+
+2000-12-07  Jeff Hobbs  <jhobbs@interwoven.com>
+
+	* generic/tcl.h: added note about need to updated
+	library/dde/pkgIndex.tcl with minor version increment.
+
+	* library/dde/pkgIndex.tcl: updated to use 84 version to reflect the
+	makefile. Should probably be updated to use its real version at some
+	point. [Patch 102560, Bug 119421]
+
+2000-12-06  Eric Melski  <ericm@ajubasolutions.com>
+
+	* generic/tcl.h (attemptckalloc): Fixed typo for #define of
+	attemptckalloc (was defined to Tcl_AttempDbCkalloc, should have been
+	Tcl_AttemptDbCkalloc). [Bug 124384]
+
+	* generic/tclCkalloc.c: Added TCL_MEM_DEBUG versions of
+	Tcl_AttemptDbCkrealloc and Tcl_AttemptDbCkalloc. [Bug 124384].
+
+2000-11-24  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclExecute.c (TclExecuteByteCode): Logical negation "!"  can
+	now handle string booleans, provided those values are placed in
+	variables.
+
+	* tests/expr.test (expr-13.17): Check that [expr {!$var}] can negate
+	the string-versions of booleans "yes", "false", etc.
+
+	* library/tcltest/tcltest.tcl (getMatchingFiles,
+	(getMatchingDirectories):

+	* tools/man2help.tcl (doDir):
+	* library/package.tcl (tclPkgUnknown,tclMacPkgSearch):
+	* library/safe.tcl (AddSubDirs): [glob] uses -directory instead of
+	unsafe [file join]. [Bug 123313]
+
+	* generic/tclIndexObj.c:
+	* generic/tclTestObj.c (TestindexobjCmd): Changed internal
+	representation of index objects to fix [Bug 119082]; fix shouldn't be
+	visible to outside world...
+
+	* generic/tclTest.c (TestGetIndexFromObjStructObjCmd):
+	* tests/indexObj.test: (indexObj-6.*) Added to test for presence of
+	[Bug 119082].
+
+2000-11-23  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Fixed memory leak from [Bug
+	119398]
+
+	* library/init.tcl (unknown): Added specific level parameters to
+	all uplevel invokations to boost performance; didn't dare touch
+	the "namespace inscope" stuff though, since it looks sensitive
+	to me!  Should fix [Bug 123217], though testing is tricky...

+2000-11-21  Andreas Kupries  <a.kupries@westend.com>
+
+	All of the changes below are described in TIP #7 ~ Specification and
+	result from the application of the patch contained therein. Creator of
+	the patch is Kevin Kenny <kennykb@crd.ge.com>. The patch used here is
+	actually a bit different. Two MS specific constant values (format
+	FOOui64) were replaced with a more portable formatting of the values
+	and an additional cast to LONGLONG. My cross-compiling gcc was unable
+	to process the original form. [Patch 102459]
+
+	* tclWinTime.c: Add to the static data a set of variables that manage
+	the phase-locked techniques, including a ''CRITICAL_SECTION'' to guard
+	them so that multi-threaded code is stable.
+
+	* tclWinTime.c: Modify ''TclpGetSeconds'' to call ''TclpGetTime'' and
+	return the 'seconds' portion of the result. This change is necessary
+	to make sure that the two times are consistent near the rollover from
+	one second to another.
+
+	* tclWinTime.c: Modify ''TclpGetClicks'' to use TclpGetTime to
+	determine the click count as a number of microseconds.
+
+	* tclWinTime.c: Modify ''TclpGetTime'' to return the time as M*Q+B,
+	where Q is the result of ''QueryPerformanceCounter'', and M and B are
+	variables maintained by the phase-locked loop to keep the result as
+	close as possible to the system clock. The ''TclpGetTime'' call will
+	also launch the phase-lock management in a separate thread the first
+	time that it is invoked. If the performance counter is unavailable, or
+	if its frequency is not one of the two common 8254-compatible rates,
+	then ''TclpGetTime'' will return the result of ''ftime'' as it does in
+	Tcl 8.3.2.
+
+	* tclWinTime.c: Add the clock calibration procedure. The calibration
+	is somewhat complex; to save space, the reader is referred to the
+	reference implementation for the details of how the time base and
+	frequency are maintained.
+
+	* tclWinNotify.c: Modify ''Tcl_Sleep'' to test that the process has,
+	in fact, slept for the requisite time by calling ''TclpGetTime'' and
+	comparing with the desired time. Otherwise, roundoff errors may cause
+	the process to awaken early.
+
+	* tclWinTest.c: Add a ''testwinclock'' command. This command returns a
+	four element list comprising the seconds and microseconds portions of
+	the system clock and the seconds and microseconds portions of the Tcl
+	clock.
+
+	* winTime.test: Add to the test suite a test that makes sure that the
+	Tcl clock stays within 1.1 ms of the system clock over the duration of
+	the test.
+
+2000-11-21  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/global.n:
+	* doc/upvar.n:
+	* doc/variable.n: Improved documentation to mention that variables so
+	created are listed in [info locals] and added a few more cross-links
+	between these commands. [Bug 119387]
+
+2000-11-17  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/safe.test: (safe-4.3):
+	* generic/tclVar.c (TclLookupVar): Changed again. Now passes all the
+	tests, though one needed modifying since it required the wrong answer.
+	(Why on earth do we have inline modification of argument strings? This
+	sort of thing is horrendous to debug and doesn't work well in a
+	multithreaded environment!) [Bug 119192]
+
+	* tests/var.test: (var-1.19) If my attempts to fix the problem aren't
+	right yet, my attempts to describe it look pretty good to me...
+
+2000-11-16  Andreas Kupries  <a.kupries@westend.com>
+
+	* win/tclWinPort.h (line 69): Changed reference to winsock2.h into
+	winsock.h. This was a leftover from a foray into using winsock version
+	2 (History lesson from Scott Redman and Jeff Hobbs). This code was no
+	problem when compiling Tcl itself, but could trip extensions. [Bug
+	122568]
+
+2000-11-15  Jeff Hobbs  <jeff.hobbs@acm.org>
+
+	* unix/Makefile.in: removed bp.c references (hasn't existed in a long
+	time). Corrected 'make dist' to make dist with unversioned library
+	directories (same as out of cvs), so make install works correctly with
+	either source tree.
+
+2000-11-15  Jeff Hobbs  <jeff.hobbs@acm.org>
+
+	* generic/tclVar.c (TclLookupVar): reverted fix below as it broke all
+	other array unset error reporting.  Bug 119192 is still open.
+
+2000-11-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclVar.c (TclLookupVar): Changed references to part2 to use
+	elName instead in various error message generating spots. [Bug 119192]
+
+2000-11-03  David Gravereaux  <davygrvy@ajubasolutions.com>
+
+	* win/.cvsignore: Removed 'configure' from the glob list now that it's
+	included.
+
+2000-11-03  Jeff Hobbs  <hobbs@ajubasolutions.com>
+
+	8.4a2 RELEASE
+
+	* unix/Makefile.in (install-libraries, dist):
+	* win/makefile.vc (install-libraries):
+	* win/Makefile.in (install-libraries): updated to install unversioned
+	library directories into versioned directories.
+
+	* tools/tcl.wse.in: updated for unversioning of library dirs
+
+	* unix/mkLinks: updated mkLinks with latest doc updates
+
+	* doc/Tcl_Main.3: added docs for Tcl_SetMainLoop
+
+	* generic/tclStubInit.c:
+	* generic/tclDecls.h:
+	* generic/tcl.decls: added Tcl_SetMainLoop proc that allows people to
+	set a main loop that will run for tclsh.
+	* generic/tcl.h: added Tcl_MainLoopProc typedef
+	* generic/tclMain.c (Tcl_SetMainLoop, StdinProc, Prompt): new
+	StdinProc and Prompt static procs and Tcl_SetMainLoop stubs proc. The
+	first two handle a fileevent based prompt (taken from tkMain.c).
+	Tcl_SetMainLoop enables the interactive setting of a main loop
+	procedure. This enables Tk to be a loadable package.
+
+2000-11-02  David Gravereaux  <davygrvy@ajubasolutions.com>
+
+	* generic/tclEvent.c: tclLibraryPath Tcl_Obj didn't have a way to
+	share its data among threads. This caused Tcl_Init() to always fail in
+	threads. Added a way to pass the data around with a global char*.
+	[BUG: 5301]
+
+2000-11-02  Jeff Hobbs  <hobbs@ajubasolutions.com>
+
+	* unix/configure:
+	* unix/dltest/configure:
+	* win/configure:
+	* tools/configure: checked in configure scripts so people doing CVS
+	checkouts aren't required to have autoconf. Changes to configure.in in
+	the future will require the corresponding configure script to also be
+	re-autoconf'ed and checked in.
+
+	* win/makefile.vc:
+	* win/tcl.m4: makefile fixes for Win64 support
+
+	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): minor cast
+	changes.
+
+2000-11-01  Jeff Hobbs  <hobbs@ajubasolutions.com>
+
+	* unix/tcl.m4: removed use of -lbsd and -ldl for AIX-5.
+
+	* tests/subst.test: added tests for non-zero return code handling by
+	subst.
+	* generic/tclParse.c (Tcl_EvalEx): corrected handling of non-zero,
+	non-error return code cases for subst. [Bug 119829]
+
+	* generic/tclVar.c (TclVarTraceExists): Corrected excessive mem use
+	when info exists was called on a non-existent array element. [Bug
+	119213, 119336]
+
+2000-10-30  David Gravereaux  <davygrvy@ajubasolutions.com>
+
+	* win/configure.in:
+	* win/Makefile.in:
+	* win/makefile.vc:
+	* win/tcl.rc:
+	* win/tclsh.rc: Added logic to derive filenames better in the resource
+	scripts based on compile options.
+
+2000-10-30  Jeff Hobbs  <hobbs@ajubasolutions.com>
+
+	* unix/tclUnixInit.c: added default encoding map from "ja_JP.eucJP" to
+	"euc-jp". (takahashi)
+
+	* tests/clock.test: corrected clock-2.* test numbering
+
+	* unix/configure.in (SC_TCL_LINK_LIBS): removed code that was
+	commented out (it had been moved to tcl.m4's SC_TCL_LINK_LIBS
+	already).
+
+	* unix/tcl.m4: consolidated gettimeofday check for AIX.
+
+2000-10-27  Jeff Hobbs  <hobbs@ajubasolutions.com>
+
+	* unix/configure.in:
+	* unix/tcl.m4: added support for AIX-5.
+
+	* generic/tclIO.c (Tcl_NotifyChannel): removed #ifdef around code for
+	old channel structures, placed preserve/release around statePtr
+	* generic/tclIO.c (CloseChannel): the statePtr for a channel was not
+	being freed when the last channel in a stack was freed, causing a mem
+	leak.
+
+	* unix/tclUnixChan.c: updated channel types to strict
+	TCL_CHANNEL_VERSION_2 style to avoid compiler warnings. They work
+	either way, but this avoids compiler warnings (that worries people).
+
+2000-10-27  Jennifer Hom  <jenn@ajubasolutions.com>
+
+	* library/tcltest1.0/tcltest.tcl: Removed a cd into the test directory
+	in runAllTests that screwed up the temporary directory setting,
+	effectively preventing users from running tests on multiple platforms
+	at the same time.
+
+2000-10-26  David Gravereaux <davygrvy@ajubasolutions.com>
+
+	* win/tclWinFile.c (TclpMatchFilesTypes): NULL was being set to "attr"
+	which was a DWORD. Changed NULL to zero because a 'void *' can't be
+	set to a DWORD to avoid the compiler warning.
+
+2000-10-24  Jennifer Hom  <jenn@ajubasolutions.com>
+
+	* tests/all.tcl: Removed support for tcltest 1.0.
+
+	* tests/tcltest.test:
+	* library/tcltest1.0/tcltest.tcl:
+	* library/tcltest1.0/pkgIndex.tcl:
+	* docs/tcltest.n: Moved tcltest2 code so that it's the standard
+	version of tcltest. Removed all tcltest2 files (tests/tcltest2.test,
+	library/tcltest1.0/tcltest2.tcl, docs/tcltest2.n).
+
+2000-10-20  Jeff Hobbs  <hobbs@ajubasolutions.com>
+
+	* win/tclWinFile.c (TclpMatchFilesTypes): made the stat call only
+	occur when necessary (for 'glob' command). Significantly speeds up
+	glob command from 8.3. [BUG: 6216]
+
+2000-10-19  Jennifer Hom  <jenn@ajubasolutions.com>
+
+	* library/tcltest1.0/tcltest2.tcl:
+	* tests/tcltest2
+	* doc/tcltest2.n: Code and documentation cleanup. Modified -verbose to
+	take list of keywords as well as string of letters. Removed Tcl
+	version information from tcltest. Removed tcltest::grep from tcltest
+	package. Added optional 3rd directory argument to
+	makeFile/makeDirectory and removeFile/removeDirectory.
+
+	* tests/basic.test: Changed references to tcltest::tclVersion to
+	hardcoded numbers.
+	* generic/tcl.h: Changed reference to tcltest2.tcl and tcltest.tcl in
+	comments to tests/basic.test.
+
+2000-10-06  David Gravereaux  <davygrvy@ajubasolutions.com>
+
+	* win/tclWinChan.c: moved Win2K bug case test with GetStdHandle() from
+	TclpGetDefaultStdChannel into Tcl_MakeFileChannel to enable a more
+	general method in detecting invalid OS handles rather than just a
+	specific known case. [BUG: 5971]
+
+2000-10-06  Jeff Hobbs  <hobbs@ajubasolutions.com>
+
+	* tests/cmdAH.test: extra tests for 'file channels' that include
+	multiple interpreter tests and channel sharing
+	* generic/tclIO.c (Tcl_GetChannelNamesEx): corrected function (and
+	consequently 'file channels') to return channels that are actually
+	registered for this specific interp, rather than this thread.
+
+	* doc/CrtChannel.3: fixed spelling mistakes
+
+2000-09-29  Jennifer Hom  <jenn@ajubasolutions.com>
+
+	* library/tcltest1.0/tcltest2.tcl:
+	* tests/tcltest2.test:
+	* doc/tcltest2.n: Modified the new form of the test command to accept
+	both attribute-value pairs and command line options. Updated the tests
+	and the documentation for this new format. Also changed the option
+	names for the test command.
+
+2000-09-29  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* win/tclWinSerial.c (SerialGetOptionProc): corrected reporting of
+	space parity on Windows (Eason) [Bug 6057].
+
+	* win/Makefile.in: commented use of TESTFLAGS
+	* unix/Makefile.in: added TESTFLAGS to test target to conform with
+	Windows makefile and TEA style.
+
+	* tests/stack.test: prevented possible crash on systems with low
+	default stacksize (Tru64, AIX) in infinite recursion test. A solution
+	to check remaining stack space in the core is best, but hard to do in
+	a cross-platform manner.
+
+	* generic/tclIOGT.c (FLUSH_DELAY): renamed DELAY define to FLUSH_DELAY
+	to avoid defn conflict using Tru64's cc.
+
+2000-09-28  Jeff Hobbs  <hobbs@ajubasolutions.com>
+
+	* tools/tcl.wse.in: added tclPlatDecls.h and tkPlatDecls.h to the
+	Windows .exe install.
+
+	* tests/fCmd.test (fCmd-6.20): corrected test to remove c:/tcl8975@
+	after creating it.
+
+	* tests/fileName.test: cleaned up the testing of glob patterns for
+	c:/globTest (Windows) to directly create/remove directory.
+
+2000-09-27  Jeff Hobbs  <hobbs@ajubasolutions.com>
+
+	* generic/tcl.decls:
+	* generic/tclIO.c: updated Tcl_IsChannelShared,
+	Tcl_IsChannelRegistered, Tcl_CutChannel, Tcl_SpliceChannel,
+	Tcl_IsChannelExisting, and Tcl_ClearChannelHandlers to conform to the
+	new stacked channel implementation. Their stub slots were also moved
+	to give preference to the new 8.3.2 stub functions. This will cause an
+	incompatability with 8.4a1 only.
+	(StopCopy): fixed a bug introduced by a partial fix in 8.3.2 that
+	didn't set nonBlocking correctly when resetting the flags for the
+	write side. [Bug: 6261]
+
+	* doc/ChnlStack.3:
+	* doc/CrtChannel.3:
+	* generic/tcl.decls:
+	* generic/tcl.h:
+	* generic/tclDecls.h:
+	* generic/tclIO.c:
+	* generic/tclIO.h:
+	* generic/tclIOGT.c:
+	* generic/tclInt.decls:
+	* generic/tclIntDecls.h:
+	* generic/tclStubInit.c:

+	* win/tclWinChan.c:
+	* win/tclWinConsole.c:
+	* win/tclWinPipe.c:
+	* win/tclWinSerial.c:
+	* win/tclWinSock.c: Up-port of changes made in 8.3.2 to 8.4a2 code
+	base. Most of these changes relate to the rewrite of the stacked
+	channel implementation, with a few config related fixes.
+
+	Following is an asynchronous include of the applicable ChangeLog
+	entries from 8.3.2.
+
+	********************************************************
+	** START OF ASYNCHRONOUS UP-PORT LOG (8.3.2 -> 8.4a2) **
+	********************************************************
+
+2000-08-07  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* doc/ChnlStack.3:
+	* doc/CrtChannel.3: updated the docs to be aware of the
+	TCL_CHANNEL_VERSION_2 style of Tcl channels.
+
+	* generic/tclIO.c (Tcl_CreateChannel): added assertion to verify that
+	the new channel versioning will be binary compatible with older
+	channel drivers.
+
+2000-08-05  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclIOGT.c (TclChannelTransform): fixed segfault that would
+	occur when transforming a channel with a proc that did not yet exist.
+	(Kupries)
+
+	* generic/tclTest.c (TestChannelCmd): added some lint init'ing of
+	statePtr and chan vars.
+
+2000-07-26  Jeff Hobbs  <hobbs@scriptics.com>
+
+	Merged core-8-3-1-io-rewrite back into core-8-3-1-branch. The
+	core-8-3-1-io-rewrite branch should now be considered defunct.
+
+	* generic/tclStubInit.c:
+	* generic/tclDecls.h:
+	* generic/tcl.decls:
+	* generic/tcl.h:
+	* generic/tclIO.c: moved the Tcl_Channel* macros from tcl.h to tclIO.c
+	and made them proper stubbed functions. These are: Tcl_ChannelName,
+	Tcl_ChannelVersion, Tcl_ChannelBlockModeProc, Tcl_ChannelCloseProc,
+	Tcl_ChannelClose2Proc, Tcl_ChannelInputProc, Tcl_ChannelOutputProc,
+	Tcl_ChannelSeekProc, Tcl_ChannelSetOptionProc,
+	Tcl_ChannelGetOptionProc, Tcl_ChannelWatchProc,
+	Tcl_ChannelGetHandleProc, Tcl_ChannelFlushProc, and
+	Tcl_ChannelHandlerProc. These should be used to access the
+	Tcl_ChannelType structure instead of direct pointer dereferencing.
+
+	* tests/iogt.test: added RCS string, marked tests 2.* to be unixOnly
+	due to underlying system differences.
+
+2000-07-25 Andreas Kupries <a.kupries@westend.com>
+
+	* tests/iogt.test: (line 866f) New tests iogt-6.[01], highlighting
+	buffering trouble when stacking and unstacking transformations.
+	iogt-6.0 is solved, see the changes below. iogt-6.1 remains, for now,
+	due to the perceived complexity of solutions.
+
+	* generic/tclIO.h: (line 139f) struct Channel, added a buffer queue,
+	to hold data pushed back when stacking a transformation.
+
+	* generic/tclIO.c:
+	(line 91f, line 7434f) New internal function 'CopyBuffer'.  Derived
+	from 'CopyAndTranslateBuffer', with translation removed.
+	(line 1025f, line 1212f): Initialization of new queue.
+	(line 1164f, Tcl_StackChannel): Pushback of input queue.
+	(line 1293f, Tcl_UnstackChannel): Discard input and pushback.
+	(line 3748f, Tcl_ReadRaw): Modified to use data in the push back area
+	before going to the driver. Uses 'CopyBuffer', s.a.
+	(line 4702f, GetInput): Modified to use data in the push back area
+	before going to the driver.
+ 	(line 4867f, Tcl_Seek): Modified to take pushback of the topmost
+	channel in a stack into account.
+	(line 5620f, Tcl_InputBuffered): See above. Added
+	'Tcl_ChannelBuffered'. Analog to 'Tcl_InputBuffered' but for the
+	buffer area in the channel.
+
+	* generic/tcl.decls: New public API 'Tcl_ChannelBuffered'. S.a.
+
+2000-07-17  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* unix/Makefile.in:
+	* win/Makefile.in:
+	* win/makefile.vc: added tclIOGT.c to objects list to compile.
+
+	* generic/tclStubInit.c:
+	* generic/tclIntDecls.h:
+	* generic/tclInt.decls: commented out internal decls for
+	TclTestChannelCmd and TclTestChannelEventCmd as they were moved to
+	tclTest.c. Added new decls for TclChannelEventScriptInvoker and
+	TclChannelTransform.
+
+	* generic/tclIO.c (CloseChannel): stopped masking out of the
+	TCL_READABLE|TCL_WRITABLE bits from the state flags in CloseChannel,
+	instead adding extra intelligence to CheckChannelErrors with a new
+	CHANNEL_RAW_MODE bit for special behavior when called from Raw channel
+	APIs.
+
+2000-07-13  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclIO.c (StackSetBlockMode): moved set of chanPtr outside of
+	blockModeProc check to avoid infinite loop when blockModeProc was
+	NULL. Updated TransformSeekProc to not call Tcl_Seek directly
+	(Kupries).
+
+	* win/tclWinChan.c: updated fileChannelType to v2 channel struct
+	* win/tclWinConsole.c: updated consoleChannelType to v2 channel struct
+	* win/tclWinPipe.c: updated pipeChannelType to v2 channel struct
+	* win/tclWinSerial.c: updated serialChannelType to v2 channel struct
+	* win/tclWinSock.c: updated tcpChannelType to v2 channel struct
+
+2000-07-11  Brent Welch	<welch@ajubasolutions.com>
+
+	* win/tclConfig.sh.in (TCL_LIBS): Cleaned up unix-specific autoconf
+	variables.
+
+2000-07-11  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tests/iogt.test: made tests [345].0 not run by default as they were
+	failing in the new design, but I'm not convinced that the returned
+	result isn't correct.
+
+	* generic/tclDecls.h:
+	* generic/tclStubInit.c:
+	* generic/tcl.decls: added Tcl_GetTopChannel C API that returns the
+	current top channel of a channel stack. Tcl_GetChannel was changed
+	earlier to return the bottommost channel of a stack because that is
+	the one that is guaranteed to stay around the longest, and this was
+	needed to compensate for certain operations that want to look at the
+	state of the main channel. Most channel APIs already compensate for
+	grabbing the top, so it shouldn't be needed often.
+
+	* generic/tclIO.c (Tcl_StackChannel, Tcl_UnstackChannel): Added
+	flushing of buffers (Kupries), removed use of DownChannel macro, added
+	Tcl_GetTopChannel public API to get to the top channel of the channel
+	stack (necessary for TLS). Rewrote Tcl_NotifyChannel for new channel
+	design (Kupries). Did some code cleanup in the transform code.
+	tclIO.c must still be broken into bits (separate out test code and
+	giot code, create tclIO.h).
+
+2000-07-10  Andreas Kupries <a.kupries@westend.com>
+
+	* tests/iogt.test: Reverted some earlier changes as a fix by Jeff
+	revived the original and correct behaviour. IOW, the tests showed a
+	genuine error and I didn't see it :(.
+
+	* generic/tclIO.c (Tcl_Read|Write_Raw): Changed to directly use the
+	drivers and not DoRead|DoWrite. The latter use the buffering system,
+	encoding and eol-translation and this wreaks havoc with the data going
+	through the transformations. Both procedures use CheckForchannelErrors
+	and let it believe that there is no background copy in progress or
+	else stacked channels could not be used for that.
+
+	* generic/tclIO.c (TclCopyChannel, CopyData): Moved access to the
+	topmost channel from the first to the second procedure to make the
+	decision about that at the last possible time (Callbacks can change
+	the stacking).
+
+	test suite: failures of iogt-[345].0
+
+2000-07-06  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tests/iogt.test: new tests for stacked channel stuff based off new
+	'testchannel transform|unstack' code (Kupries IOGT extension).
+	* generic/tcl.decls:
+	* generic/tcl.h:
+	* generic/tclDecls.h:
+	* generic/tclStubsInit.c:
+	* generic/tclIO.c: complete rewrite of Tcl Channel code for stacked
+	channels. Channels are now designed to work in a more stacked fashion
+	with a shared ChannelState data structure.
+
+2000-06-02  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclIO.c (CloseChannel): removed the &ing out of
+	(TCL_READABLE|TCL_WRITABLE) from the flags, as CloseChannel does this
+	on the next pass through for the top channel, and it appeared to be
+	causing hangs by not allowing the final flush.
+
+2000-06-01  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclIO.c (CloseChannel): Rewrote CloseChannel code to unstack
+	a channel during the close process. Fixed a refcount bug in
+	Tcl_UnstackChannel. [Bug: 5623]
+	(CloseChannel): further extended CloseChannel in the stacked case to
+	effect certain operations on the next channel that would have been
+	done in Tcl_Close.  Also added CHANNEL_CLOSED and removed
+	(TCL_READABLE|TCL_WRITABLE) bits from chanPtr->flags. Changed final
+	reset of the WatchProc to check the chanDownPtr's (next) interestMask.

+2000-09-20  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tests/socket.test: removed doTestsWithRemoteServer constraint from
+	socket-12.*. It requires 'exec', not a remote server. Cleaned up some
+	coding errors.
+
+2000-09-20  Jennifer Hom  <jenn@ajubasolutions.com>
+
+	* library/tcltest1.0/pkgIndex.tcl: Updated to load tcltest 2.0.
+	* library/tcltest1.0/tcltest2.tcl: New version of tcltest.
+	Cleanup of command line parsing: allows users to specify command line
+	arguments through an environment variable named TCLTEST_OPTIONS [RFE:
+	3748], does not respond to incorrect arguments, and forces usage of
+	entire flag name when using command line arguments. Defines accessor
+	procs for all tcltest variables. Allows users to use 'return' in test
+	scripts. Allow users to specify whether test files should be sourced
+	or run in a separate process. 'all.tcl' code moved to tcltest package.
+	'test' proc modified to use attribute-value pairs. Allow users to
+	specify what return codes, output, and errors can be compared and
+	whether these values should be compared using regexp, glob, or exact
+	matching. makeDirectory & removeDirectory now operate with respect to
+	temporaryDirectory [Bug: 6001]. Test results from tests run in slave
+	interpreters are now included in test totals [Bug: 1493]. Test files
+	that return error values are now reported.
+	* tests/all.tcl: Added code to check for the tcltest version loaded;
+	modified to figure out which tests to run based on the tcltest version
+	loaded.
+	* tests/tcltest.test: Modified to explicitly load version 1.0 of
+	tcltest.
+	* tests/tcltest2.test: New test suite for tcltest; includes all of the
+	old tests plus new ones reflecting changes made for version 2.0.
+	* tests/cmdAH.test: Added singleTestInterp constraint to cmdAH-31.2;
+	this test does not run if tests aren't sourced into a single
+	interpreter.
+	* tests/socket.test: Fixed two tests that were referencing variables
+	outside of scope.
+
+	* tools/tcl.wse.in: Added code to install tcltest2.tcl.
+
+	* doc/tcltest2.n: New documentation for tcltest version 2.0. Removes
+	documentation for tcltest namespace variables. Adds documentation for
+	new tcltest procs.
+
+	* unix/mkLinks: Added code to link to tcltest2.n.
+
+	* generic/tcl.h: Added comment to modify tcltest2.tcl as well as
+	tcltest.tcl for version changes.
+
+2000-09-19  Eric Melski  <ericm@ajubasolutions.com>
+
+	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd): When using -all, all attempts
+	after the first to match the regexp against the string should include
+	the TCL_REG_NOTBOL flag, to avoid erroneously matching ^ in the middle
+	of the string. Added code to set this flag after the first pass
+	through the matching loop. [Bug: 6284].
+
+2000-09-19  David Gravereaux  <davygrvy@ajubasolutions.com>
+
+	* doc/Eval.3: Added a note about the script argument to Tcl_Eval()
+	should be in UTF-8 or risk implied conversion errors when possible
+	combinations of upper ascii can be valid UTF-8 special codes.
+
+2000-09-17  Eric Melski  <ericm@ajubasolutions.com>
+
+	* tests/cmdIL.test: Added a test for fix for [Bug: 6212].
+
+	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Applied patch from [Bug:
+	6212], which corrected an error in the handling of the -index option.
+
+2000-09-14  Eric Melski  <ericm@ajubasolutions.com>
+
+	* doc/Alloc.3: Added entries for Tcl_AttemptAlloc, Tcl_AttempRealloc.
+
+	* doc/StringObj.3: Added entry for Tcl_AttemptSetObjLength.
+
+	* generic/tclDecls.h:
+	* generic/tclStubInit.c: Regen'ed stubs files from new tcl.decls.
+
+	* generic/tcl.decls: Added stubs for the Tcl_Attempt* memory
+	allocators and for Tcl_AttemptSetObjLength.
+
+	* generic/tcl.h: Added #define's for attemptckalloc, attemptckrealloc,
+	which map to the Tcl_Attempt* memory allocators.
+
+	* generic/tclCkalloc.c: Added non-panic'ing versions of Tcl_Alloc,
+	Tcl_Realloc, etc.; these are called Tcl_AttemptAlloc,
+	Tcl_AttemptRealloc, etc. These are used by Tcl_AttemptSetObjLength and
+	the string obj append functions.
+
+	* generic/tclStringObj.c: Modified string growth algorithm to use
+	doubling algorithm as long as possible, and only fall back when that
+	fails. Added Tcl_AttemptSetObjLength, and modified
+	AppendUnicodeToUnicodeRep, AppendUtfToUtfRep, and
+	Tcl_AppendStringsToObjVA to support this.
+
+2000-09-07  David Gravereaux <davygrvy@ajubasolutions.com>
+
+	* win/.cvsignore: changed the glob patterns a bit to exclude VC++
+	project conversion backups.
+
+	* win/tclWinPipe.c: Stage-1 bug fix for TR#2460 "exec leaks memory".
+	Added more logic around the close-down of the pipe reader thread so as
+	to avoid, at all cost, a TerminateThread. Most cases with exec are
+	fixed, but I don't consider 2460 done yet. Closing down the read side
+	of a pipe before the child process, doesn't really fit the windows
+	model. [BUG: 2460]
+
+2000-09-07  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* doc/trace.n: minor doc cleanup
+
+2000-09-06  André Pönitz <poenitz@htwm.de>
+
+	* doc/*.n: added or changed "SEE ALSO:" section
+
+2000-09-06  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* win/tclWinLoad.c (TclpLoadFile): added special message for
+	ERROR_PROC_NOT_FOUND exception in loading a dll.
+	* win/tclWinError.c: changed ERROR_PROC_NOT_FOUND to map from ESRCH
+	(POSIX: no such process) to EINVAL because there is no good mapping
+	for "procedure not found".
+
+	* README:
+	* generic/tcl.h:
+	* library/tcltest1.0/tcltest.tcl:
+	* tools/tcl.wse.in:
+	* tools/tcltk-man2html.tcl:
+	* unix/configure.in:
+	* unix/tcl.spec:
+	* win/README.binary:
+	* win/configure.in: updated patchlevel to 8.4a2
+
+	* unix/tclUnixPipe.c (TclpCreateProcess): Removed WNOHANG from
+	Tcl_WaitPid call in error case of process creation on Unix, as it
+	would lead to defunct processes. [Bug: 6148]
+
+	* tests/string.test: extended string repeat tests
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): changed STR_REPEAT to
+	preallocate the full space of the final string, avoided repeated
+	appends.
+
+	* doc/source.n:
+	* doc/Eval.3: added extra note about how to safe use ^Z in code, as it
+	is now a cross-platform (was just Windows) EOF char.
+
+2000-09-05  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclHash.c: fixed pedantic warning of incorrectly placed
+	#endif
+
+	* generic/tclExecute.c (TclExecuteByteCode): INST_STR_INDEX fixed
+	pedantic cast warning.
+	Corrected support for building with -DTCL_COMPILE_STATS.
+	Added efficiency check of object equality.
+
+2000-08-29  Eric Melski  <ericm@ajubasolutions.com>
+
+	* generic/tclStringObj.c: Applied patch from Gerhard Hintermayer to
+	provide a more conservative string growth algorithm for strings larger
+	than one megabyte; this allows more efficient use of memory for very
+	large strings.
+
+2000-08-25  Eric Melski  <ericm@ajubasolutions.com>
+
+	* tests/trace.test: Extended array tracing tests.
+
+	* doc/trace.n: Clarified information about when array traces will be
+	fired.
+
+	* generic/tclVar.c (Tcl_ArrayObjCmd): Corrected call to CallTraces
+	(for TCL_TRACE_ARRAY) to only be called when the variable is either an
+	array or is undefined, to ensure that array traces do not fire for
+	scalar variables.
+
+2000-08-24  Eric Melski  <ericm@ajubasolutions.com>
+
+	* doc/man.macros: Tweaked tab settings for .SO (Standard Options)
+	sections, based on suggestion from Peter Spjuth.
+
+2000-08-24  Mo DeJong  <mdejong@redhat.com>
+
+	* unix/README: Update to account for removal of --enable-gcc.
+	* unix/configure.in:
+	* unix/tcl.m4 (SC_ENABLE_GCC): Remove --enable-gcc option.
+	* win/README: Add note about building with Cygwin.
+	* win/configure.in:
+	* win/tcl.m4 (SC_ENABLE_GCC): Remove --enable-gcc option. Remove quick
+	hack that provided cross compile support for windows builds.
+
+2000-08-24  Eric Melski  <ericm@ajubasolutions.com>
+
+	Overall change: Added support for command rename/delete traces and new
+	trace syntax, from patch from Vince Darley. Added support for array
+	traces for variables. [RFE: 5048, 5967].
+
+	* doc/trace.n: Updated documentation for new syntax; flagged old
+	syntax as deprecated; added documentation for command rename/delete
+	traces and variable array traces.
+
+	* tests/trace.test: Updated tests for new trace syntax; new tests for
+	command rename/delete traces; new tests for array traces.
+
+	* generic/tclVar.c: Support for new trace syntax; support for
+	TCL_TRACE_ARRAY.
+
+	* generic/tclStubInit.c:
+	* generic/tclDecls.h:
+	* generic/tcl.decls: Stub functions for command rename/delete traces.
+
+	* generic/tcl.h:
+	* generic/tclInt.h:
+	* generic/tclBasic.c: Support for command traces.
+
+	* generic/tclCmdMZ.c (TclTraceVariableObjCmd): Patched to support new
+	[trace] syntax:
+	trace {add|remove|list} {variable|command} name ops command
+	Added support for command traces (rename, delete operations).
+	Added support for TCL_TRACE_ARRAY at Tcl level (array operation for
+	variable traces).
+
+2000-08-20  Eric Melski  <ericm@ajubasolutions.com>
+
+	* generic/tclVar.c: Added check for non-arrays for [array statistics]
+	command (patch from Mark Patton).
+
+2000-08-19  David Gravereaux <davygrvy@ajubasolutions.com>
+
+	* generic/tclPlatDecls.h: without a previous '#include <windows.h>',
+	tclPlatDecls.h can't be parsed due to a missing definition of TCHAR.
+	Added a check to include it when not defined.
+
+	***POSSIBLE OBSCURE BUG*** could be caused when the compile flags for
+	the core happen to be different than a project who uses these publics
+	regarding -D_MBCS and -D_UNICODE. This added check might have to be
+	revisited later with a better understanding of the reprocusions. I
+	think TCHAR should be replaced with it's expansion.
+
+2000-08-18  David Gravereaux <davygrvy@ajubasolutions.com>
+
+	* win/.cvsignore (added): provides a cleaner build environment with
+	graphical CVS clients.
+
+2000-08-15  Eric Melski  <ericm@ajubasolutions.com>
+
+	* library/tcltest1.0/tcltest.tcl: Set debug level in
+	tcltest::restoreState to 2, for consistancy with the debug level in
+	tcltest::saveState [Bug: 4505].
+
+2000-08-14  Eric Melski  <ericm@ajubasolutions.com>
+
+	* win/makefile.vc:
+	* win/Makefile.in:
+	* unix/Makefile.in: Added tclPlatDecls.h to the list of installed
+	headers, for more complete stubs support. [Bug: 5241].
+
+	* generic/tcl.h: Added #include "tclPlatDecls.h" to get
+	platform-specific stubs declarations (Tcl_WinTCharToUtf, etc)
+	[Bug: 5241].
+
+	* README: Updated link for instructions on compiling Tcl from sources
+	to point to correct location (http://dev.scriptics.com/doc/... instead
+	of http://dev.scriptics.com/support/...).
+
+2000-08-11  Eric Melski  <ericm@ajubasolutions.com>
+
+	* generic/tclEnv.c (TclUnsetEnv): Changed declaration of length
+	variable from "unsigned int" to "int", to match usage when passed to
+	TclpFindVariable [Bug: 6126].
+
+2000-08-10  Eric Melski  <ericm@ajubasolutions.com>
+
+	* library/msgcat1.0/pkgIndex.tcl: Bumped version number to 1.2 [Bug:

+
+	* library/msgcat1.0/msgcat.tcl: Removed erroneous [package forget] in
+	msgcat namespace initializer. Bumped version number to 1.2 [Bug: 6100]
+
+2000-08-10  David Gravereaux <davygrvy@ajubasolutions.com>
+
+	* generic/tclObj.c: r1.15 accidentally changed a global mutex name

+	insert a space before the message component when objc == 0 [Bug: 6078]
+
+2000-07-27  Mo DeJong  <mdejong@redhat.com>
+
+	* win/configure.in: TCL_STUB_LIB_FLAG should not include ${TCL_DBGX}
+	in win/tclConfig.sh, fix that.

+	alerting on all platforms as it was only working on Win before.
+	Removed older Win hacks that would end-up waking the wrong notifier in
+	the presence of a threaded build. All tests pass as before. New test
+	cases will be added soon for the new behavior. [BUG: 5791]
+
+2000-07-25  Eric Melski  <ericm@ajubasolutions.com>
+
+	* generic/tclVar.c (CallTraces): Added check for VAR_TRACE_ACTIVE on
+	the array containing the variable before executing traces on that
+	array, to conform with normal variable traces and the documentation,
+	which states that while executing a trace, other traces on that
+	variable are disabled. [Bug: 6049].
+
+	* win/tclWinPipe.c (BuildCommandLine): Added Tcl_DStringFree call to
+	prevent potential memory leaks [Bug: 6041].

+	giving the wrong answer. This made TclpGetDefaultStdChannel grab what
+	it thought was a valid native stdout handle. Added a new WriteFile()
+	test to make sure it's really valid. This OS bug doesn't affect the
+	shells. Only -subsystem:windows (aka WinMain) application that
+	dynamically load tclXX.dll [BUG: 5971]

+	* library/msgcat1.0/msgcat.tcl:
+	* doc/msgcat.n:
+	* tests/msgcat.test: Applied patches from Chris Nelson, to provide the

+	mcload to use utf-8 encoding on when reading message catalog files,
+	and provides for better default behavior for determining the locale on
+	a Windows system.

+
+	* tests/http.test
+	* doc/http.n
+	* library/http2.3/http.tcl: Fixed bug 5741, where unsuccessful geturl
+	calls sometimes leaked memory and resources (sockets). Also, switched
+	around some of the logic so that http::wait never throws an exception.
+	This is because in an asynchronous geturl, the command callback will
+	probably end up doing all the error handling anyway, and in an
+	asynchronous situation, the user expects to check the state when the
+	transaction completes, as opposed to being thrown an exception.	For
+	the http package, this menas the user can check http::status for
+	"error" and http::error for the error message after doing the
+	http::wait.

+
+	Overall changes:
+	  (1) Implementation of joinable threads for all platforms.
+	  (2) Additional API's for channels. Required to allow the thread
+	      extension to move channels between threads.
+
+	* generic/tcl.decls (lines 1360f): Added Tcl_JoinThread,
+	Tcl_IsChannelShared, Tcl_IsChannelRegistered, Tcl_CutChannel,
+	Tcl_SpliceChannel, Tcl_IsChannelExisting and Tcl_ClearChannelHandlers
+	(slots 394 to 400).
+
+	* generic/tclIO.c: Implemented Tcl_IsChannelRegistered,
+	Tcl_IsChannelShared, Tcl_CutChannel, Tcl_SpliceChannel,
+	Tcl_IsChannelExisting and Tcl_ClearChannelHandlers.  Tcl_CutChannel
+	uses code from CloseChannel. Replaced this code by a call to
+	Tcl_CutChannel. Replaced several code fragments adding channels to
+	the channel list with calls to Tcl_SpliceChannel. Removed now unused
+	variables from CloseChannel and Tcl_UnstackChannel.
+	Tcl_ClearChannelHandlers uses code from Tcl_Close. Replaced this code
+	by a call to Tcl_ClearChannelHandlers. Removed now unused variables
+	from Tcl_Close. Added the subcommands 'cut', 'forgetch', 'splice' and
+	'isshared' to the test code (TclTestChannelCmd).
+
+	* unix/tclUnixThread.c: Implemented Tcl_JoinThread using the
+	pthread-functionality.
+
+	* win/tclWinThrd.c: Fixed several small typos in comments.
+	Implemented Tcl_JoinThread using a platform independent emulation
+	layer (see generic/tclThreadJoin.c below). Added 'joinLock' to
+	serialize Tcl_CreateThread and TclpExitThread to prevent a race for
+	joinable threads.
+
+	* mac/tclMacThrd.c: Implemented Tcl_JoinThread using a platform
+	independent emulation layer (see generic/tclThreadJoin.c below). Due
+	to the cooperative nature of threading on this platform the race
+	mentioned above is not present.
+
+	* generic/tclThreadJoin.c: New file. Contains a platform independent
+	emulation layer helping in the implementation of joinable threads for
+	the win and mac platforms.
+
+	* generic/tclInt.h: Added declarations for TclJoinThread,
+	TclRememberJoinableThread and TclSignalExitThread. These procedures
+	define the API of the emulation layer for joinable threads (see
+	generic/tclThreadJoin.c above).
+
+	* win/Makefile.in:
+	* win/makefile.vc: Added generic/tclTheadJoin.o to the rules.
+
+	* mac/: I don't know to which file generic/tclTheadJoin.o has to be
+	added to so that it compiles. Sorry.
+
+	* unix/tclUnixChan.c: #ifdef'd the thread-local list of file channels
+	as it prevents us from transfering channels. To restore this we may
+	need an extended interface to drivers in the future. Target:
+	9.0. Found while testing the new transfer of channels. The information
+	in this list for a channel was left behind and then crashed the system
+	during finalization.
+
+	* generic/tclThreadTest.c: Added -joinable flag to 'testthread
+	create'. Added subcommand 'testthread join'.
+
+	* doc/CrtChannel.3: Added documentation for Tcl_IsChannelRegistered,
+	Tcl_IsChannelShared, Tcl_CutChannel, Tcl_SpliceChannel,
+	Tcl_IsChannelExisting and Tcl_ClearChannelHandlers.
+
+	* doc/Thread.3: Added documentation for Tcl_JoinThread.
+

+	TCL_MEM_DEBUG usage.
+
+	* doc/DumpActiveMemory.3: Man page for Tcl_DumpActiveMemory,
+	Tcl_InitMemory, and Tcl_ValidateAllMemory [Bug: 1816, 1835].
+
+	* generic/tclCkalloc.c: Fixed some function headers.
+
+	* unix/mkLinks: Regen'd with new mkLinks.tcl.
+
+	* unix/mkLinks.tcl: Fixed indentation, made link setup more
+	intelligent (only do one existance test per man page, instead of one
+	per function).
+
+	* doc/library.n: Fixed .SH NAME macro to include each function
+	documented on the page, so that mkLinks will know about the functions
+	listed there, and so that the Windows help file index will get set up
+	correctly [Bug: 1898, 5273].

+	These changes make some error handling marginally better for Mac

+
+	* mac/tclMacSock.c (TcpClose): Add timeouts to the close - these don't

+	socket errors out, then return EWOULDBLOCK & error out.
+	* mac/tclMacSock.c (NotifyRoutine): Added a NotifyRoutine for
+	experimenting with MacTCP.
+
+2000-04-22  Jim Ingham <jingham@cygnus.com>
+

+	search part of tclPkgUnknown.
+
+2000-04-21  Sandeep Tamhankar <sandeep@scriptics.com>
+
+	* library/http2.1/http.tcl: Fixed a newly introduced bug where if
+	there's a -command callback and something goes wrong, geturl threw an
+	exception, called the callback, and unset the token. I changed it so
+	that it will not call the callback when throwing an exception (so the
+	caller only finds out about a given error from one place).  Also,
+	fixed http::ncode so that it actually gives you back the http return
+	code (i.e. 200, 404, etc.) instead of the first digit of the version
+	of HTTP being used (i.e. 1).
+
+2000-04-21  Brent Welch <welch@scriptics.com>
+
+	* library/http2.1/http.tcl: More thrashing with the "server closes
+	without reading post data" scenario. Reverted to the previous filevent
+	configuratiuon, which seems to work better with small amounts of post
+	data.
+
+2000-04-20  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclAlloc.c: wrapped caddr_t define to not be done on Unix
+	* unix/tclUnixPort.h: added Tclp*Alloc defines to allow the use of
+	USE_TCLALLOC on Unix. [Bug: 4731]
+
+2000-04-19  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* library/dde1.1/pkgIndex.tcl:
+	* library/reg1.0/pkgIndex.tcl:
+	* win/tclWinChan.c:
+	* win/tclWinThrd.c: converted CRLF to LF the */tcl.hpj.in files were
+	not converted, as it confuses hcw locally. [Bug: 5096]
+
+	* win/Makefile.in: expanded cleanup target for help files
+
+	* doc/Thread.3: minor macro cleanup
+
+	* generic/tclFileName.c (SplitUnixPath): added support for QNX node

+
+2000-04-10  Eric Melski  <ericm@scriptics.com>
+
+	* win/tclWinPipe.c (TclpCreateTempFile): Added conversion of contents
+	string from UTF to native encoding [Bug: 4030].
+
+	* tests/regexp.test: Added tests for infinite looping in [regexp
+	-all].
+
+	* generic/tclCmdMZ.c: Fixed infinite loop bug with [regexp -all]
+	[Bug: 4981].
+
+	* tests/*.test: Changed all occurances of "namespace import
+	::tcltest" to "namespace import -force ::tcltest" [Bug: 3948].
+
+2000-04-09  Brent Welch <welch@scriptics.com>
+
+	* lib/httpd2.1/http.tcl: Worked on the "server closes before reading
+	post data" case, which unfortunately causes different error cases on
+	Solaris, which can read the reply, and Linux and Windows, which cannot
+	read anything. This is all in the loop-back case - client and server
+	on the same host. Also unified the error handling so the "ioerror"
+	status goes away and errors are reflected in a more uniform way.
+	Updated the man page to document the behavior.
+
+2000-04-09  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tests/reg.test (matchexpected): corrected tests to use tcltest
+	constraint types to skip certain tests.
+
+	* generic/tclBasic.c (Tcl_SetCommandInfo): comment fix
+
+	* unix/tclUnixThrd.c (Tcl_CreateThread): moved TCL_THREADS ifdef
+	inside of func as it is declared for non-threads builds as well. In
+	the non-threads case, it always returns TCL_ERROR (couldn't create
+	thread).
+
+2000-04-08  Andreas Kupries <a.kupries@westend.com>
+
+	* Overall change: Definition of a public API for the creation of
+	new threads.
+
+	* generic/tclInt.h (line 1802f): Removed the definition of
+	'TclpThreadCreate'. (line 793f) Removed the definition of
+	'Tcl_ThreadCreateProc'.
+
+	* generic/tcl.h (line 388f): Readded the definition of
+	'Tcl_ThreadCreateProc'. Added Win32 stuff send in by David Graveraux
+	<davygrvy@bigfoot.com> to that too (__stdcall, ...). Added macros for
+	the default stacksize and allowed flags.
+
+	* generic/tcl.decls (line 1356f): Added definition of
+	'Tcl_CreateThread', slot 393 of the stub table. Two new arguments in
+	the public API, for stacksize and flags.
+
+	* win/tclWinThrd.c:
+	* mac/tclMacThrd.c: Renamed TclpThreadCreate to Tcl_CreateThread,
+	added handling of the stacksize. Flags are currently ignored.
+
+	* unix/tclUnixThrd.c: See above, but handles joinable flag. Ignores
+	the specified stacksize if the macro HAVE_PTHREAD_ATTR_SETSTACKSIZE is
+	not defined.
+
+	* generic/tclThreadTest.c (line 363): See below.
+
+	* unix/tclUnixNotfy.c (line 210): Adapted to the changes above. Uses
+	default stacksize and no flags now.
+
+	* unic/tcl.m4 (line 382f): Added a check for
+	'pthread_attr_setstacksize' to detect platforms not implementing this
+	feature of pthreads. If it is implemented, configure will define the
+	macro HAVE_PTHREAD_ATTR_SETSTACKSIZE (See unix/tclUnixThrd.c too).
+
+	* doc/Thread.3: Added Tcl_CreateThread and its arguments to the list
+	of described functions. Removed stuff about not providing a public
+	C-API for thread-creation.
+
+2000-04-07  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* doc/binary.n: clarified docs on sign extension in binary scan [Bug:
+	3466]
+
+	* library/tcltest1.0/tcltest.tcl (initConstraints): removed win32s
+	references (no longer supported)
+
+	* tests/fCmd.test: marked test 8.1 knownBug because it is dangerous on
+	poorly configured systems [Bug: 3881] and added 8.2 to keep essence of
+	8.1 tested.
+
+2000-04-05  Andreas Kupries <a.kupries@westend.com>
+
+	* generic/tclIO.c (Tcl_UnstackChannel, line 1831): Forcing interest
+	mask to the correct value after an unstack and re-initialization of
+	the notifier via the watchProc. Without this the first fileevent after
+	an unstack will come through and be processed, but no more. [Bug: ??].
+
+2000-03-04  Brent Welch  <welch@scriptics.com>
+
+	* {win,unix}/Makefile.in: added dependency of tclStubInit.c on
+	tcl.decls and tclInt.decls
+	* generic/tclThread.c: Tweak so this compiles w/out TCL_THREADS
+	* generic/{tcl.decls,tclStubInit.c}:  Just touched the tcl.decls and
+	regenerated the tclStubInit.c file
+
+2000-03-29  Sandeep Tamhankar <sandeep@scriptics.com>
+
+	* library/http2.1/http.tcl: For the -querychannel option, fconfigure
+	the socket to be binary so that we don't translate anything while
+	reading the data. This is because we determine the content length of
+	the data on the channel by using seek (to the end of the file) and
+	tell on the file handle, and we need the content-length to match the
+	amount of data actually sent, and translation can affect the number of
+	bytes posted.
+
+2000-04-03  Andreas Kupries <a.kupries@westend.com>
+
+	* Overall change: Definition of public API's for the finalization of
+	conditions and mutexes. [Bug: 4199].
+
+	* generic/tclInt.h: Removed definitions of TclFinalizeMutex and
+	TclFinalizeCondition.
+
+	* generic/tcl.decls: Added declarations of Tcl_MutexFinalize and
+	Tcl_ConditionFinalize.
+
+	* generic/tclThread.c: Renamed TclFinalizeMutex to Tcl_MutexFinalize.
+	Renamed TclFinalizeCondition to Tcl_ConditionFinalize.
+
+	* generic/tclNotify.c: Changed usage of TclFinalizeMutex to
+	Tcl_MutexFinalize.
+
+	* unix/tclUnixNotfy.c:
+	* generic/tclThreadTest.c: Changed usages of TclFinalizeCondition to
+	Tcl_ConditionFinalize.
+
+	* generic/tcl.h: Added empty macros for Tcl_MutexFinalize and
+	Tcl_ConditionFinalize, to be used when the core is compiled without
+	threads.
+
+	* doc/Thread.3:	Added description the new API's.
+
+2000-04-03  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclCmdIL.c (InfoVarsCmd): checked for non-NULL procPtr to
+	prevent itcl info override crash [Bug: 4064]
+
+	* tests/foreach.test:
+	* tests/namespace.test:

+
+	* tools/man2help2.tcl: fixed winhelp cross-linking error [Bug: 4156]

+
+2000-04-03  Eric Melski  <ericm@scriptics.com>
+
+	* unix/tclUnixFCmd.c (SetGroupAttribute):
+	* unix/tclUnixFCmd.c (SetOwnerAttribute): Added (uid_t) and (gid_t)
+	casts to avoid compiler warnings.
+
+2000-03-31  Eric Melski  <ericm@scriptics.com>
+
+	* generic/tclGet.c (Tcl_GetDouble): Added additional conditions to
+	error test (previously only errno was checked, but the return value of
+	strtod() should be checked as well). [Bug: 4118]
+
+	* tests/exec.test: Added test for proper conversion of UTF data when
+	used with "<< $dataWithUTF" on exec's.
+
+	* unix/tclUnixPipe.c (TclpCreateTempFile): Added
+	Tcl_UtfToExternalDString call, so that if there is UTF content in the
+	string it will be properly converted to the system encoding before
+	being written [Bug: 4030].
+	(TclpCreateTempFile): Added a check on the return value of tmpnam;
+	some systems (Linux, for example) will start to return NULL after
+	tmpnam has been called TMP_MAX times; not checking for this can have
+	bad results (overwriting temp files, core dumps, etc.)
+
+2000-03-30  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclBasic.c (Tcl_DeleteCommandFromToken): Added comments
+	noting the need to pair ckalloc with ckfree. [Bug: 4262]
+
+	* generic/tclInt.decls:
+	* generic/tclIntPlatDecls.h:
+	* generic/tclStubInit.c:
+	* win/tclWin32Dll.c: removed TclWinSynchSpawn (vestige of Win32s
+	support).
+
+	* win/tclWinReg.c: made use of TclWinGetPlatformId instead of getting
+	info again
+
+	* win/tclWinPort.h:
+	* win/Makefile.in:
+	* win/configure.in:
+	* win/tcl.m4: Added support for gcc/mingw on Windows [Bug: 4234]
+
+2000-03-29  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclCompile.c (TclCleanupByteCode): made ByteCode cleanup
+	more aware of TCL_BYTECODE_PRECOMPILED flagged structs (gen'd by
+	tbcload), to correctly clean them up.
+
+	* generic/tclClock.c (FormatClock): moved check for empty format
+	earlier, commented 0 result return value
+
+2000-03-29  Sandeep Tamhankar <sandeep@scriptics.com>
+
+	* library/http2.1/http.tcl: Removed an unnecessary fileevent statement
+	from the error processing part of the Write method. Also, fixed two
+	potential memory leaks in wait and reset, in which the state array
+	wasn't being unset before throwing an exception. Prior to this
+	version, Brent checked in a fix to catch a fileevent statement that
+	was sometimes causing a stack trace when geturl was called with
+	-timeout. I believe Brent's fix is necessary because TLS closes bad
+	sockets for secure connections, and the fileevent was trying to act on
+	a socket that no longer existed.
+
+2000-03-27  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tests/httpd: removed unnecessary 'puts stderr "Post Dispatch"'
+
+	* tests/namespace.test:
+	* generic/tclNamesp.c (Tcl_Export): added a uniq'ing test to the
+	export list so only one instance of each export pattern would exist in
+	the list.
+
+	* generic/tclExecute.c (TclExecuteByteCode): optimized case for the
+	empty string in ==/!= comparisons
+
+2000-03-27  Eric Melski  <ericm@scriptics.com>
+
+	* unix/tclUnixChan.c: Added (off_t) type casts in lseek() call [Bug:
+	4409].
+
+	* unix/tclLoadAout.c:
+	* unix/tclUnixPipe.c: Added (off_t) type casts in lseek() calls [Bug:
+	4410].
+
+2000-03-22  Sandeep Tamhankar <sandeep@scriptics.com>
+
+	* library/http2.1/http.tcl: Fixed a bug where string query data that
+	was bigger than queryblocksize would get duplicate characters at block
+	boundaries.
+
+2000-03-22  Sandeep Tamhankar <sandeep@scriptics.com>
+
+	* library/http2.1/http.tcl: Fixed bug 4463, where we were getting a
+	stack trace if we tried to publish a project to a good host but a port
+	where there was no server listening.  It turned out the problem was a
+	stray fileevent that needed to be cleared.  Also, fixed a bug where
+	http::code could stack trace if called on a bad token (one which
+	didn't represent a successful geturl) by adding an http element to the
+	state array in geturl.
+
+2000-03-21  Eric Melski  <ericm@scriptics.com>
+
+	* tests/clock.test: Modified some tests that were not robust with
+	respect to the time zone in which they were run and were thus failing.
+
+	* doc/clock.n: Clarified meaning of -gmt with respect to -base when
+	used with [clock scan] (-gmt does not affect the interpretation of
+	-base).
+
+2000-03-19  Sandeep Tamhankar <sandeep@scriptics.com>
+
+	* library/http2.1/http.tcl: geturl used to throw an exception when the
+	connection failed; I accidentally returned a token with the error
+	info, breaking backwards compatibility. I changed it back to throwing
+	an exception, but unsetting the state array first (thus still
+	eliminating the original memory leak problem).
+
+2000-03-19  Sandeep Tamhankar <sandeep@scriptics.com>
+
+	* library/http2.1/http.tcl: Added -querychannel option and altered
+	some of Brent's modifications to allow asynchronous posts (via
+	-command). Also modified -queryprogress so that it calls the query
+	callback as <callback> <token> <total size> <current size> to be
+	consistent with -progress. Added -queryblocksize option with default
+	8192 bytes for post blocksize. Fixed a bunch of potential memory leaks
+	for the case when geturl receives bad args or can't open a socket,
+	etc. Overall, the package really rocks now.
+
+	* doc/http.n: Added -queryblocksize, -querychannel, and
+	-queryprogress. Also, changed the description of -blocksize, which
+	states that the -progress callback will be called for each block, to
+	now qualify that with an "if -progress is specified".
+
+	* tests/http.test: Added a querychannel test for synchronous and
+	asynchronous posts, altered the queryprogress test such that the
+	callback conforms to the -progress format. Also, had to use the
+	-queryblocksize option to do the post 16K at a time to match Brent's
+	expected results (and to test that -queryblocksize works).
+
+2000-03-15  Brent Welch <welch@scriptics.com>
+
+	* library/http2.1/http.tcl: Added -queryprogress callback to
+	http::geturl and also changed it so that writing the post data is
+	event driven if the queryprogress callback or a timeout is given.
+	This allows a timeout to occur when writing lots of post data. The
+	queryprogress callback is called after each block of query data is
+	posted. It has the same signature as the -progress callback.
+
+2000-03-06  Eric Melski  <ericm@scriptics.com>
+
+	* library/package.tcl: Applied patch from Bug: 2570; rather than
+	setting geometry of slave interp to 0x0 when Tk was loaded, it now
+	does "wm withdraw .". Both remove the main window from the display,
+	but the former caused some internal structures to get initialized to
+	zero, which caused crashes with some extensions.
+
+2000-03-02  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* library/package.tcl (tclPkgUnknown): extended to allow recognizes
+	changes in the auto_path while sourcing in other pkgIndex.tcl files
+
+	* doc/FindExec.3: fixed doc for declaration of Tcl_FindExecutable
+	[Bug: 4275]
+
+	* generic/tclFileName.c (Tcl_TranslateFileName): Applied patch from
+	Newman to significantly speedup file split/join on Windows (replaces
+	regexp with custom parser). [Bug: 2867]
+
+	* win/README.binary: change mailing lists from @consortium.org to
+	@scriptics.com [Bug: 4173]
+
+2000-02-28  Eric Melski  <ericm@scriptics.com>
+
+	* tests/clock.test: Added test for ISO bases < 100000
+
+	* generic/tclDate.c: (generated on Solaris)
+	* generic/tclGetDate.y: Changed condition for deciding if a number is
+	an ISO 8601 base from number >= 100000 to numberOfDigits >= 6.
+	Previously it would fail to recognize 000000 as an ISO base.
+
+2000-02-14  Eric Melski  <ericm@scriptics.com>
+
+	* unix/Makefile.in: Added rpm target to generate Tcl binary RPM.
+
+	* unix/tcl.spec: RPM specification file for a Tcl binary RPM for
+	Linux.
+
+2000-02-10  Jeff Hobbs  <hobbs@scriptics.com>

+
+	* changes: updated for 8.3.0 release
+
+	* doc/load.n: added notes about dll load errors on Windows
+
+	* unix/README:

+
+	* tests/unixInit.test: fixed japanese LANG encoding test [Bug: 3549]
+
+	* unix/configure.in:
+	* unix/tcl.m4: correct CFLAG_WARNING setting, fixed gcc config for
+	AIX, added -export-dynamic to LDFLAGS for FreeBSD-3+ [Bug: 2998]
+
+	* win/tclWinLoad.c (TclpLoadFile): improved error message for load
+	failures, could perhaps be even more intelligent.
+
+2000-02-09  Jim Ingham	 <jingham@cygnus.com>
+
+	* mac/tclMacSock.c: Don't panic when you get an error closing an async
+	socket. This doesn't seem to hurt anything, and we return the error so
+	the caller can do the right thing.
+
+	New Files:
+	* mac/MW_TclHeader.h:
+	* mac/MW_TclTestHeader.h:
+	* mac/MW_TclTestHeader.pch:

+
+	* tests/pkg/magicchar2.tcl:
+	* tests/autoMkindex.test: Test for auto loader fix (bug #2480).
+
+	* library/init.tcl: auto_load was using [info commands $name] to
+	determine if a given command was available; if the command name had *
+	or [] it, this would fail because info commands uses glob-style
+	matching. This is fixed. (Bug #2480).
+

+	* tests/pkgMkIndex.test: Tests for fix for bug #2360.

+	* tests/autoMkindex.test: Test for fix for bug #2611.
+
+	* library/auto.tcl: Fixed the regular expression that performs $

+
+	* tests/autoMkindex.test:

+2000-01-27  Jennifer Hom  <jenn@scriptics.com>
+
+	* library/tcltest1.0/tcltest.tcl: Changed NormalizePath to

+	option.
+	Fixed bug #1983, dealing with pkg_mkIndex incorrectly handling
+	situations with two procs by the same name but in different namespaces
+	(ie, foo::baz and bar::baz).

+
+	* generic/tclClock.c (FormatClock): inlined resultPtr, as it
+	conflicted with var creation for HAVE_TZSET #def [Bug: 4063]

+	systems (UTS) require sys/types.h to be included first [Bug: 4031]
+
+	* unix/tclUnixChan.c (CreateSocketAddress): changed comparison with -1
+	to 0xFFFFFFFF, to ensure 32 bit comparison even on 64 bit systems.

+	Mac. (Darley)
+
+	* generic/tclInt.h:

+	(now behavior is consistant with docs too) (bug #981).
+
+2000-01-20  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* generic/tclCmdIL.c (InfoBodyCmd): made [info body] return a string
+	if the body has been bytecompiled.

+
+	* tests/set.test: added test for complex array elem name compiling

+	protection in Tcl_UnsetVar2.
+
+	* generic/tclVar.c: Added protection in Tcl_UnsetVar2 against attempts

+	happen if there was an unset trace on an array element and the trace
+	proc made a global or upvar link to the array, and then the array was
+	unset at the global level. See the bug reference for more information.
+
+	* unix/tclUnixTime.c: New clock format format.
+
+	* compat/strftime.c: New clock format format.

+
+	Up-port to 8.4 of mac code changes for 8.3.3 & various new changes for
+	8.4, some already backported to 8.3.4. [Patch 435658]
+
+	* generic/tclObj.c: added #include to fix missing prototype errors
+
+	* generic/tcl.h: MAC_TCL: addition of ConditionalMacros.h and use of
+	DLLIMPORT and DLLEXPORT like on other platforms. ( => no longer need
+	the .exp files and can remove use of #pragma export that never worked
+	well)
+	removed line continuation in #if clause as this breaks the mac
+	resource compiler (note that *.r files include tcl.h)
+
+	* mac/tclMacFile.c: fixed bug in permission checking code
+
+	* mac/tclMacLoad.c: corrected utf8 handling, comparison of package
+	names to code fragment names changed to only match on the length of
+	package name, this allows for fragment names with version numbers
+	appended.
+
+	* mac/tclMacInt.h:
+	* generic/tclInt.h:
+	* mac/tclMacTime.c:
+	* generic/tclIOUtil.c: moved declaration of TclpGetGMTOffset()

+
+	* mac/MW_TclAppleScriptHeader.pch:
+	* mac/MW_TclHeader.pch:
+	* mac/MW_TclTestHeader.pch:
+	* mac/tclMacCommonPch.h: revised precompiled header handling: now
+	include a common header file 'MW_TclHeaderCommon.h' from all .pch
+	files, the .pch files themselves now only setup #defines (e.g.
+	BUILD_tcl, STATIC_BUILD, TCL_DEBUG, TCL_THREADS) like in makefiles on
+	other platforms.
+
+	* mac/tclMac.h:
+	* mac/tclMacPort.h:
+	* mac/tclMacInt.h: use of BUILD_tcl and TCL_STORAGE_CLASS like on other
+	platforms, standardize #include'd files to what's done on other
+	platforms, removed use of #pragma export.
+
+	* mac/tcltkMacBuildSupport.sea.hqx: new archive of mac build support
+	files & suggested build environment directory hierarchy:
+	'Building MacTclTk' & 'CW Pro6 changes' readme's.
+	projects for MoreFiles 1.5.2 static & shared libraries.
+	project & sources for 'pseudoCarbonSupport', see below.
+	included XML versions of the projects for CW Pro5 or Pro7 users.
+
+	* mac/tclMacProjects.sea.hqx: updated mac build project files:
+	build support for CodeWarrior Pro6, UnivIntf 3.4 & shared runtime
+	libraries: the MSL libraries and MoreFiles are no longer compiled into
+	Tcl.shlb, all non-static binaries now use the Pro6 shared runtime
+	libraries and MoreFiles.shlb.  These shlbs are merged into the standard
+	Wish and TclShell, but 3rd party applications linking with Tcl.shlb or
+	Tk.shlb need to setup access to them.  (see the "(sh-ppc)" targets
+	for how to do this.)
+	included XML versions of the projects for CW Pro5 or Pro7 users.
+	use compat/strtod.c instead of MSL's strtod()
+	use WASTE versions of MSL for tcl test target to avoid text buffer
+	cutoff at 32k.
+	Merging the full MSL.shlb and the other shlbs into Wish & TclShell
+	makes them a bit larger than before, use unmerged binaries to avoid
+	copying the shared code with every application, e.g. when deploying
+	numerous Wish based droplets.
+	Note that using CW Pro5 to compile extensions is in principle still
+	possible, but need to link with Pro6 runtime libraries.
+	Tclapplescript now loads and runs on CFM68k.
+	Highly experimental "pseudoCarbon" support for Tcl only on OS 8/9:
+	binaries in "Build:(Carbon):" link against CarbonLib instead of
+	InterfaceLib, however the actual code has not been carbonized! i.e. it
+	will not run on OSX and may not even run properly with CarbonLib.
+	This should in principle allow you to build & test OS9 CFM Carbon
+	binaries that need to link with Tcl.shlb. On OSX you can use the
+	native Tcl.framework, but you have to build a MachO binary as there
+	is no CFM glue lib for Tcl.framework.
+	the library pseudoCarbonSupport.shlb manually loads the symbols from
+	InterfaceLib that are not in CarbonLib but are needed by the
+	uncarbonized code in Tcl.shlb and TclShell.
+
+	* generic/tclMain.c: MAC_TCL: workaround for broken/non-standard isatty
+	on MW Pro6, #include <unistd.h> instead of defining isatty
+
+	* mac/tclMacPort.h: MW Pro6 changes for MSL fcntl.h, stat.h & isatty
+
+	* mac/tclMacAppInit.c: add EXTERN to InstallConsole to enable DLL
+	export via the TCL_STORAGE_CLASS mechanism.
+
+	* mac/tclMacFCmd.c: fix for FSpDirectoryCopy API change
+
+	* mac/tclMacLibrary.c: emit compile time error when
+	TCL_REGISTER_LIBRARY and USE_TCL_STUBS are both defined at the same
+	time in an extension, this use is not currently supported and will
+	result in a crash when dynamically loading the extension.
+
+	* mac/tclMacApplication.r:
+	* mac/tclMacLibrary.r:
+	* mac/tclMacOSA.r:
+	* mac/tclMacResource.r: fixed obsolete copyrights/dates in version
+	strings; updated version strings to standard usage; added support for
+	'(Support Libraries)' subfolder for shared runtime libraries in
+	unmerged binaries; commented out demo setting of "Tcl Environment
+	Variables"; reorganized resources among these files to avoid multiple
+	copies in applications and shared libraries, the script libraries are
+	now no longer duplicated in Tclsh but are only included in the
+	resources of Tcl.shlb.
+
+	* mac/tclMacChan.c:
+	* mac/tclMacSock.c: cast for *BlockMode
+
+	* mac/tclMacUtil.c:
+	* mac/tclMacMath.h: removed obsolete hypot() definition
+
+	* generic/tclIntPlatDecls.h:
+	* generic/tclInt.decls:
+	* generic/tclStubInit.c:
+	* mac/tclMacNotify.c:
+	* mac/tclMacOSA.c:
+	* mac/tclMacUtil.c:
+	* generic/tclThreadTest.c: renamed routines conflicting with standard
+	Apple or MoreFiles headers (at compile or link time):
+	GetGlobalMouse         -> GetGlobalMouseTcl
+	FSpGetDirectoryID      -> FSpGetDirectoryIDTcl
+	FSpOpenResFileCompat   -> FSpOpenResFileCompatTcl
+	FSpCreateResFileCompat -> FSpCreateResFileCompatTcl
+	NewThread              -> NewTestThread
+	the renamed MoreFiles *Tcl routines are just wrappers calling into the
+	MoreFiles DLL.
+
+	* mac/tclMacCommonPch.h:
+	* mac/tclMacThrd.c:
+	* mac/tclMacPanic.c: removed OLDROUTINENAMES define, renamed obsolete
+	apple API names to modern equivalents; UH3.4 support: added #include
+	<ControlDefinitions.h>, updated New*Proc() calls to New*UPP().
+
+	* mac/tclMacUnix.c: added missing (Tcl_Obj ***) cast to
+	Tcl_ListObjGetElements call
+
+	* mac/tclMacAlloc.c: modernized TclpSysAlloc() to use temporary memory
+	instead of system heap memory when available (MacOS >= 7.5 and
+	possibly earlier, use of system heap has been discouraged for a long
+	time and has many disadvantages, e.g. memory isn't paged out, and
+	errors can very easily bring the system down); fixed crashing bug in
+	TclpSysRealloc() and CleanUpExitProc() where memory was being accessed
+	after having been deallocated; fixed memory leak in (de)allocation
+	code (for every block ever allocated with TclpSysAlloc, a Ptr was
+	leaked), if temporary memory is available, don't track allocated
+	memory, instead use RecoverHandle() to get Handle from Ptr, otherwise
+	use doubly linked list to correctly track memory and free all
+	allocated memory; added new option for ConfigureMemory:
+	MEMORY_DONT_USE_TEMPMEM, disables use of temporary memory even when it
+	would be available, only necessary when writing e.g. a driver (using
+	tcl??); increased fraction of application heap reserved for OS
+	routines to 512K
+
+	* compat/strftime.c:
+	* mac/tclMacTime.c:
+	* mac/tclMacPort.h:
+	* generic/tclInt.decls:
+	* generic/tclIntPlatDecls.h:
+	* generic/tclStubInit.c: timezone support for mac via TclpGetTZName()
+	like on windows, using an inverse timezone table adapted from
+	tclDate.c to map gmtoffset in seconds gotten from the MacOS APIs to a
+	timezone string, as there is no good way to get this info from MacOS.
+	I had to make up some unusual timezones and arbitrarily decide on the
+	most standard of the multiple choices available for every timezone.
+
+	* generic/tclExecute.c: workaround for a MSL bug/misfeature: for very
+	small floats, MSL can return errno ERANGE but a non-zero value (<
+	LDBL_MIN however)
+
+	* mac/tclMacAppInit.c: support for WASTE text library using temporary
+	memory, setting has no effect if WASTE is not used.
+
+	* mac/tclMacPanic.c: removed duplicate code from generic/tclPanic.c
+	and added that file to projects instead.
+
+	* tests/all.tcl: set tcltest::singleProcess 1 as multiple processes
+	are not available on the mac.
+
+	* tests/cmdAH.test: access time not available on the mac, skip the
+	atime touch test
+
+	* tests/appendComp.test:

+	* tests/exec.test:

+	* tests/tcltest.test: added missing cleanups/tests/catches that caused
+	tests to fail on the mac.
+
+	* doc/tclvars.n: doc bug, env(PWD) should be env(HOME) [Bug 463834]
+
+2001-11-21  Don Porter	<dgp@users.sourceforge.net>
+
+	* tests/trace.test (trace-8.8): Corrected test for Bug 219393.
+
+	* generic/tclBasic.c (Tcl_DeleteCommandFromToken,CallCommandTraces):
+	* generic/tclCmdMZ>c (Tcl_UntraceCommand):  Added Tcl_Preserve and
+	Tcl_Release calls to prevent deletion of CommandTrace structures until
+	all callers are done using them, preventing memory corruption. [Bug
+	453805]
+
+2001-11-20  Kevin B. Kenny  <kennykb@users.sourceforge.net>

+	Changed all uses of TclpGetTime to Tcl_GetTime. Added Tcl_GetTime to
+	the Stubs table and the library documentation. Added a TclpGetTime in
+	tclUtil.c for backward compatibility of extensions. [Patch 483500,
+	TIP#73]
+
+	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): Corrected an error in the

+2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclBasic.c
+	* generic/tclCompile.h:
+	* generic/tclExecute.c: moving all code relative to bytecodes from
+	tclBasic.c to tclExecute.c - the functions RecordTracebackInfo and
+	Tcl_ExprObj went to tclExecute.c, and new interface function was
+	defined (TclCompEvalObj).
+	The final objective of this sequence of moves is to provide a clean,
+	clear-cut interface between Tcl's core and the compiler/engine
+	subsystem.
+
+2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclBasic.c
+	* generic/tclCompile.h:
+	* generic/tclExecute.c: factoring out of common code in tclBasic.c
+	(new function TclInterpReady defined: it resets the interp's result,
+	then checks that it hasn't been deleted and that the nesting level is
+	acceptable). Passed the responsibility of calling it to the *callers*
+	of TclEvalObjvInternal.
+
+2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclBasic.c
+	* generic/tclExecute.c: a better variant of the previous-to-last
+	commit (restoring numLevels computations). The managing of the levels
+	now has to be done by the *callers* of TclEvalObjvInternal
+
+2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c: missing variable declaration under

+
+2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c:
+	* generic/tclProc.c: restoring the computations of iPtr->numLevels to

+
+2001-11-20  Jeff Hobbs  <jeffh@ActiveState.com>
+

+	* unix/Makefile.in: added EOL correction for Windows bat files to

+
+	* unix/tclUnixInit.c (TclpSetInitialEncodings): update of patch from
+	2001-11-16 that uses the old Tcl encoding check mechanism as a
+	fallback to the original. Also added a TCL_DEFAULT_ENCODING #define
+	(defaults to iso8859-1). Tcl will first try setlocale and nl_langinfo,
+	and if that fails, guess based on certain LANG|LC_* env vars. [Patch
+	418645]
+
+2001-11-19  David Gravereaux <davygrvy@pobox.com>

+	between NT/2000 and the older operating systems. Added test to ensure
+	normalization is correct.
+
+2001-11-19  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclBasic.c:
+	* generic/tclParse.c: Code reorganisation. Moved all evaluation
+	functions from tclParse.c to tclBasic.c, so that now tclParse.c deals
+	exclusively with parsing and all evaluations are done by code in
+	tclBasic.c. The functions moved are: TclEvalObjvInternal,
+	Tcl_EvalObjv, Tcl_LogCommandInfo, Tcl_EvalTokensStandard,
+	Tcl_EvalTokens, Tcl_EvalEx, Tcl_Eval, Tcl_EvalObj and
+	Tcl_GlobalEvalObj.
+
+2001-11-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/trace.test (trace-8.8): Added adapted version of [Bug 219393]
+	as new test; the test won't reliably show up the old problem unless it
+	is being run under something like Purify, but something is better than
+	nothing...
+
+	* generic/tclVar.c (Tcl_TraceVar2, Tcl_UntraceVar2): Added missing
+	mask bits for trace result type and a check for a nonsense flag
+	combination.
+	* generic/tclCmdMZ.c (TraceVarProc): Added missing test for NULL when
+	deleting a trace that doesn't cause an error.
+
+	* doc/TraceVar.3: Added documentation for change due to TIP#68.
+
+	* generic/tclCmdMZ.c (TraceVarInfo): Removed problematic errMsg field
+	from structure.
+	(TraceVarProc): Removed references to errMsg field and changed
+	handling of errors so that they returned a Tcl_Obj* containing the
+	error string. This minimizes the number of calls to the memory
+	management subsystem.
+	(TclTraceCommandObjCmd, TraceCommandProc): Removed references to
+	errMsg field which was never used in command traces in any case.
+	(Tcl_TraceObjCmd, TclTraceVariableObjCmd): Removed references to
+	errMsg field and made variable traces register with
+	TCL_TRACE_RESULT_OBJECT bit set.
+
+	* generic/tcl.h (TCL_TRACE_RESULT_DYNAMIC,TCL_TRACE_RESULT_OBJECT):
+	New constants to define how to handle the strings returned from trace

+

+	when not under NT with it's scrollback console. Then it replays it,

+2001-11-08  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/Makefile.in:
+	* unix/dltest/Makefile.in: Avoid adding libc to the LIBS variable
+	since it is not needed when linking with CC. If required when linking
+	with LD it should be done on a case by case basis in tcl.m4.
+
+2001-11-08  David Gravereaux <davygrvy@pobox.com>
+
+	* win/rules.vc:
+	* win/makefile.vc:  Fixed install target to adjust for the different

+	Everything else know is done.
+
+	* win/tcl.dsp(new):
+	* win/tcl.dsw(new):  Simple MsDev stub project files that calls

+
+2001-11-07  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/Makefile.in:

+	We can't regenerate automatically since there may be no tclsh on the

+2001-11-07  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	Define TCL_INCLUDE_SPEC in tclConfig.sh. It should be included by

+
+	* win/rules.vc:
+	* win/makefile.vc: Dropped the NOMSVCRT macro and put it on the option
+	list instead. It makes more sense to me this way as NOMSVCRT=0 would
+	only be the valid setting. Fixed the dde and reg extension for
+	building static. Improved, but not perfected, the winhelp target.
+
+2001-11-07  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/README: Change minimum VC++ version to 5.X since 4.X is known

+	what URLs folks should use to download the supported version of Mingw.
+	* win/configure: Regen.
+	* win/configure.in: Error out if user tries to compile the Windows

+	instead.
+
+2001-11-06  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* generic/tclIO.c (ReadChars): Fixed [Bug 478856] reported by Stuart
+	Cassoff <stwo@users.sourceforge.net>. The bug caused loss of
+	fileevents when [read]ing less data from the channel than buffered.
+	Due to an empty input buffer the flag CHANNEL_NEED_MORE_DATA was set
+	but never reset, causing the I/O system to wait for more data instead
+	of using a timer to synthesize fileevents and to flush the pending
+	data out of the buffers.
+
+2001-11-06  David Gravereaux <davygrvy@pobox.com>
+
+	* win/rules.vc (new):
+	* win/makefile.vc:  Complete over/under rewrite to support numerous
+	build options all from the commandline itself without needing to edit
+	the makefile. Now requires vcvars32.bat to be run prior to running
+	nmake for bootstraping the environment. Fully doc'd usage for it is in
+	makefile.vc. Commentary welcome. Sticky points left are:
+
+	1) winhelp target shows errors in the converting script.
+	2) .rc scripts aren't getting the right #defines to build the correct
+	   "OriginalFilename" strings. (have patch, won't commit yet)
+	3) Naming convention with suffixes describing the buildtype are 'tsdx'
+	   which will need public acceptance. ie. tclsh84tsx.exe is a (t)
+	   threaded shell (s) statically linked to the core and (x) uses
+	   msvcrt instead of libcmt.

+2001-10-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

+
+2001-10-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* unix/tclUnixChan.c: Added stateUpdated member to struct TtyState.
+	(TtyCloseProc,TtySetOptionProc,TtyInit): Use stateUpdated member of
+	TtyState to decide whether it is necessary to reset a serial port when
+	Tcl closes it. Blindly resetting can cause Tcl to be sent an
+	unexpected SIGTSTP when it is executing in the background [Bug 471374,

+	Report and patch by David N. Welton <davidw@users.sourceforge.net>.
+
+	* The changes below fix [Bug 462317] where Expect tried to read more
+	than was in the buffers and then blocked in the OS call as its pty
+	channel driver provides no blockmodeproc through which the OS could be
+	notified of blocking-behaviour. Because of this the general I/O core
+	has to take more care than usual to preserve the semantics of
+	non-blocking channels.
+
+	The problem was reported by "Kevin O'Gorman" <kevin@kosmanor.com>.
+
+	* generic/tclIO.c (Tcl_ReadRaw): Do not read from the driver if the
+	channel is non-blocking and the fileevent causing the read was
+	generated by a timer. We do not know if there is data available from
+	the OS. Instead of going to the OS for more and potentially blocking
+	we simply signal EWOULDBLOCK to the higher levels to cause the system
+	to wait for true fileevents.
+	(GetInput): Same as before.
+	(ChannelTimerProc): Added set and clear of CHANNEL_TIMER_FEV.
+
+	* generic/tclIO.h (CHANNEL_TIMER_FEV): New flag for channels. Is set
+	if a fileevent was generated by a timer, the channel is not blocking
+	and the driver did not provide a blockmodeproc. In that case the I/O
+	core has to be especially careful about going to the driver for more
+	data.

+
+2001-09-06  Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+	* All the changes below serve to fix bug [219148] which reports a 80x
+	performance hit for file I/O on Win* systems. On my system it was
+	closer to a 120x hit. Problem report by Uwe Traum <no email address
+	available>.
+
+	The fix goes like this: The obstacle is 'FlushFileBuffers', executed
+	whenever Tcl writes data to the OS, as Tcl has to wait for the disk to
+	complete I/O, and disks are slow. We remove that obstacle. This opens
+	another problem, [file size] reports back wrong numbers. So for [file
+	size] we add the call back in. As optimization we keep track of the
+	channels which were written to and flush only these.
+
+	* win/tclWinFile.c (TclpObjStat): Added a call to
+	'TclWinFlushDirtyChannels'. This ensures that [file size] and related
+	commands report the correct size of a file even if Tcl has recently
+	written to it. Unixoid OS's always report the correct size even for
+	files with pending data, but Win* syssystem don't. They only report
+	what is actually on disk.
+
+	* win/tclWinInt.h: Added declaration of 'TclWinFlushDirtyChannels',
+	making it available to other parts of the tcl core.
+
+	* win/tclWinChan.c (TclWinFlushDirtyChannels): New, internal,
+	procedure. Goes through the list of open file channels and forces the
+	OS to flush its file buffers for all which were written to since the
+	last call of this function. This is an expensive operation as Tcl has
+	to wait for the OS to complete actual writes to the disk.
+
+	(FileInfo): Added dirty flag required by the procedure above.
+
+	(FileOutputProc): Removed flushing of file buffers, setting the dirty
+	flag instead. This means that the previously incurred delays do not
+	happen anymore.
+
+	(TclWinOpenFileChannel): Added initialization of 'dirty' flag.

+	and convert text according to specified encoding (if known). RFC
+	iso8859-1 is used by default. Also recognize Content-encoding to see
+	if we should do binary translation. Added a CYA -binary switch for the

+	inform the filesystem that the filesystem epoch must be changed (since
+	cached filesystems may now be incorrect). Fixes problem running tclvfs
+	extension.
+	* library/tcltest/tcltest.tcl: if tests aren't in a native filesystem,
+	then don't use pipes to run them. [Bug 458741]
+
+2001-09-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tcl.decls (479 generic):
+	* generic/tclIO.c (Tcl_Seek,Tcl_Tell,Tcl_OutputBuffered): Added public
+	function to return the size of the output buffer and reworked other
+	channel functions to use this shared functionality and that of
+	Tcl_InputBuffered() too. [TIP#49, Rolf Schroedter]
+
+2001-09-05  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tclPlatDecls.h:  Another small trim finalizing Borland
+	support.
+
+	* win/tclWinPipe.c:
+	* win/tclWinPort.h:  More Borland compatibility fixes. Changed EDQUOT
+	#define from 49 to 69. Borland had a clash as it was already using
+	this number. Upon advice from Helmut Giese, EDQUOT has been found in
+	other header files #defined as 69. [Patch 436116]
+
+	* win/.cvsignore:  A few more glob patterns added.
+
+	* win/makefile.bc (new):  Borland lives once more! rejoice..
+	* generic/tclAlloc.c: Small Borland compatibility fix.
+	* win/tclWinTime.c:  More Borland compatibility fixes. [Patch 436116]
+
+2001-09-05 Vince Darley <vincentdarley@users.sourceforge.net>
+
+	* tests/winFCmd.test: made notWin2000 constraint false if not running
+	on Windows at all.
+
+2001-09-04  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinThrd.c:  Revisited _beginthreadex() stuff. Instead of
+	assuming a c-runtime implimentation of _beginthreadex normal, I
+	reversed the logic to not assume, and use when is by explicitly
+	needing to add runtimes that support it such as Borland.
+
+	* generic/tcl.h:
+	* generic/tclPlatDecls.h:  Borland compatibility change so ClientData
+	was properly typed as a void* and TCHAR would not be defined twice.
+
+	* generic/tcl.h:  Removed a small mistake from before. Changes to the
+	EXTERN macro for proper Borland compatibility will have to see a TIP.
+	What's this with the MS compiler:
+
+		__declspec(dllexport) int func (int a, int b);
+
+	will have to be this with Borland:
+
+		int __cdecl __export func (int a, int b);
+
+	The order of the attribute needs to be after the return type.
+
+2001-09-04  Don Porter  <dgp@users.sourceforge.net>
+
+	* compat/strtod.c (strtod):  Fixed failure to handle expressions like
+	3eq2 and failure to set errno on overflow. [Bug 440894]
+
+2001-09-04  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclProc.c:

+	names. [Bug 458548]
+
+2001-09-04 Vince Darley <vincentdarley@users.sourceforge.net>
+
+	Minor bug fixes in filesystem, plus small vfs changes as a result of
+	enabling the test filesystem to work properly.
+	* tests/fileName.test: ensure new test cleans up after itself
+	* doc/filename.n:
+	* generic/tclFileName.c: improved Mac path handling and document why
+	[Bug 421842] on Windows handling of UNC paths is not valid.
+	Documentation and code now much clearer on what is and is not a UNC
+	path.
+	* doc/FileSystem.3:
+	* unix/tclUnixPipe.c:
+	* generic/tclFCmd.c:
+	* generic/tclIOUtil.c: fixed error message, fixed [Bug 453512] about
+	dangerous use of tmpnam, replaced with mkstemp. Documented all the
+	changes.
+	* generic/tclTest.c: made test vfs fully functional as a 'reporting
+	filesystem'.
+	* generic/tcl.stubs:
+	* generic/tcl.h:
+	* generic/tclInt.h:
+	* generic/tclIOUtil.c:
+	* doc/file.n:
+	* various platform-specific 'TclpLoadFile': fixed comments about
+	unload behaviour, and completed objectification of loading. Required
+	change to Tcl_Filesystem lookup table, so incompatible with 8.4a3, but
+	not older versions of Tcl. The change also allows 'link' and
+	'reporting' filesystems to function correctly when loading files.
+	Implementation of 'file delete -force' copes with case where cwd is
+	inside the directory. Moved overlooked Tcl_FSGetPathType from internal
+	to external API. Made sure filesystems which are registered and then
+	unregistered are only freed when all references to them are gone.
+	Documented changes.
+	* unix/tclUnixFCmd.c: when deleting directories recursively, make sure
+	permissions are ok. Together with the above, this fixes [Bug 219139]
+	* tests/winFCmd.test: differentiated test results for win2k versus
+	not. This fixes [Bug: 219239]
+	* tests/fCmd.test: added tests for 'file delete -force' where the cwd
+	is inside, and when permissions are inadequate.
+
+2001-09-04  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompile.c: fixed incorrect operands for INST_LIST [Bug

+
+2001-09-03  Jeff Hobbs  <jeffh@ActiveState.com>
+

+	debug macro.
+
+2001-09-03  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/ExprLongObj.3: Fixed error in documentation of argument type to
+	Tcl_ExprObj [Bug 457435]
+
+2001-09-02  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinThrd.c:  Portability fix for Cygwin who's c-runtime,
+	not surprisingly, doesn't have the MSVCRT specific _beginthreadex /
+	_endthreadex pair. This might have to be revisited for proper Borland,
+	lcc32, Watcom and other support as well. [Patch 444255]
+
+	* win/tclWinThrd.c:  Moved FinalizeConditionEvent() proto to within
+	the main #ifdef TCL_THREADS block to avoid mingw warning about it
+	being there but unused.
+
+	* win/makefile.vc:  Added -Zl (zee el) to tclStubLib.c compile line to
+	make sure the tclstub84.lib static library is built without requiring
+	a specific C-runtime library at link-time for the end-use developer.
+	It has been noted on c.l.t that this trips many first time users
+	trying to make extensions. [Patch 403533]
+
+2001-08-31  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclInt.h: added TclCompileListCmd header
+	* generic/tclBasic.c: added TclCompileListCmd compile proc
+	* generic/tclCompCmds.c (TclCompileListCmd): function to compile the
+	'list' command at parse time.
+	* generic/tclExecute.c (TclExecuteByteCode): definition of INST_LIST
+	bytecode.
+
+	* doc/StringObj.3: added words of warning to use Tcl_ResetResult with
+	the Tcl_Append* functions.
+
+	* tests/compile.test: added compile-11.* interp result checks
+	* generic/tclUtil.c (TclGetIntForIndex): added Tcl_ResetResult before
+	Tcl_AppendStringsToObj to prevent shared object crash when called from
+	bcc instruction. The Tcl_Append* calls that append to the result
+	object that are invoked by bcc insts must remember to call
+	Tcl_ResetResult because the bcc doesn't do this for us. [Bug 456892]
+
+2001-08-30  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclIndexObj.c: fixed some casting problems that upset Crays.
+	[Bug 419528] (andreasen)
+
+2001-08-30  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tcl.h: Silence warning from Sun compiler. [Bug 454374]
+
+2001-08-30  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c: allow cached fully-qualified command names to
+	be usable from different namespaces within the same interpreter
+	without forcing a new lookup. This speeds up scripts that pass command
+	names in variables ("this" in some OO packages). [Patch 456668]
+
+2001-08-30 Vince Darley <vincentdarley@users.sourceforge.net>
+
+	Further fs updates. After examining the most common Tcl extensions
+	(TclX, BLT, Tk, TclPro, Mktclapp), it has been determined that only
+	TclpGetCwd and the Access/Stat/Open insert/delete hooks of the
+	internal fs functions are ever used. The remaining functions from
+	Tcl's internal interfaces have therefore been removed, since Tcl now
+	exports a more suitable public API (Tcl_FS...)
+
+	* generic/tclInt.stubs:
+	* generic/tclInt.h: updated for removed internal functions. Some new
+	internal functions have been put in tclInt.h (and not exported in the
+	stub table because good public equivalents exist).
+	* generic/tclTest.c: some test functions used the internal private
+	APIs. These tests have been retained, but modified to use public APIs.
+	Also objectified the internal filesystem tests.
+	* win/tclWinFile.c: removed TclpStat, TclpAccess and refactored code
+	to use NativeAccess, NativeStat. This should speed up stat, access and
+	glob commands.
+	* win/tclWinFCmd.c: removed all TclpCopy/Rename/Delete File/Directory
+	string-based procedures which aren't used any more. Improved
+	efficiency of some other procedures. Ensure that filename conversions
+	with a NULL interp do not crash Tcl.
+	* mac/tclMacFCmd.c: wrapped long lines and cleaned up
+	TclpObjNormalizePath, removed all TclpCopy/Rename/Delete
+	File/Directory string-based procedures which aren't used any more.
+	* mac/tclMacFile.c: removed obsolete TclpStat, TclpAccess, TclpChdir,
+	etc.
+	* unix/tclUnixFCmd.c: removed use of TclpAccess, removed all
+	TclpCopy/Rename/Delete File/Directory string-based procedures which
+	aren't used any more.
+	* unix/tclUnixFile.c: removed obsolete TclpStat, TclpAccess,
+	TclpChdir, etc.
+	* tcl(Unix|Mac|Win)Chan.c: objectified TclpOpenFileChannel.
+	* various 'load' implementations all objectified.
+	* generic/tclFileName.c: removed redundant code.
+	* generic/tclIOUtil.c: removed TclStat, TclAccess, TclpListVolumes.
+	Fix to MatchInDirectory at the root of a volume. Also improved some
+	documentation, and improved default path joining behaviour for virtual
+	filesystems, especially regarding '~'.
+	* tests/fileName.test: added tests to check for bugs fixed above.
+	* doc/FileName.3: improved documentation
+
+2001-08-30  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tclAsync.c:
+	* generic/tclEvent.c:
+	* generic/tclInt.h: Improper cleanup of asyncMutex in tclAsync.c
+	repaired. TclFinalizeSynchronization() was trying to remove a
+	registered mutex that was dumped earlier when the TSD it was stored in
+	was cleared. This was only surfacing on *nix. Windows was being masked
+	by mutexes not actually being returned to the system! That was
+	repaired in a previous patch. Needed to add a private
+	TclFinalizeAsync() to tclAsync.c and called from Tcl_FinalizeThread().
+	Pheww.. Is this done yet? [Bug 414419] requested by Rob Ratcliff
+	<rrr6399@futuretek.com>
+
+2001-08-28  Jeff Hobbs  <jeffh@ActiveState.com>

+
+2001-08-26  Don Porter <dgp@users.sourceforge.net>
+
+	* library/auto.tcl (tcl_findLibrary):
+	* tests/unixInit.test (unixInit-2.{1,9}):
+	* unix/tclUnixInit.c (TclpInitLibraryPath):
+	* win/tclWinInit.c (TclpInitLibraryPath):  Corrected inconsistency
+	between  the search path for script libraries and the directory name
+	$DISTNAME into which distributions built by 'make test' unpack. [Bug
+	455642]
+
+2001-08-24  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tests/stringComp.test: added string-1.3
+	* generic/tclCompCmds.c (TclCompileStringCmd): changed to return
+	TCL_OUT_LINE_COMPILE instead of TCL_ERROR when compiling and an
+	unknown string method is called. This is necessary as the string
+	command may be never called, or not until 'string' is redefined.
+
+2001-08-24 Vince Darley <vincentdarley@users.sourceforge.net>
+
+	* doc/glob.n: documented windows-style path issue with glob.
+	[Bug 219392]
+	* doc/filename.n: documented windows path/file length limitation.
+	[Bug 454597]
+
+2001-08-24  Don Porter <dgp@users.sourceforge.net>
+
+	* tests/unixInit.test (unixInit-2.9): Corrected expected result to
+	match Tcl's quirky construction of its init library path.
+
+2001-08-23  Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+	* win/tclWinPipe.c (BuildCommandLine): Fixed [Bug 432499]. Part of the
+	code used the non-absolute path to the executable to determine
+	quoting. This failed if the absolute path contained spaces, but the
+	application name itself not. This bug caused no trouble on Win NT 5,
+	but does for other variants in the Win* family. Report and fix due to
+	Ken Poole <kenpoole@users.sourceforge.net>.
+
+2001-08-23  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* unix/configure:
+	* unix/tcl.m4: added QNX-6 build support. [Bug 219410] (loverso)
+
+	* unix/tclUnixFCmd.c:
+	* generic/tclIOUtil.c:
+	* generic/tclFileName.c: corrected minor compiler warnings.
+
+2001-08-23 Vince Darley <vincentdarley@users.sourceforge.net>
+
+	Variety of small filesystem and vfs issues fixed or improved. The new
+	fs code allows many new opportunities for efficiency improvements
+	through the objectified API. The main changes integrated here are such
+	efficiency improvements. Some limitations of the original
+	implementation have also now been lifted. Meanwhile a variety of fs
+	bugs (some old, some new) have also been fixed.
+
+	* generic/tclFileName.c: Made Tcl_FSSplitPath more efficient, and
+	removed some static string-based procedures which are no longer used.
+	Much more objectification. Tcl_FSJoinPath is now very efficient and
+	more aware of virtual filesystems. Clarified where the Mac-specific
+	code attempts to interpret Unix-style paths. Modified TclDoGlob to use
+	lstat not access to fix [Bug 434876] (L. Virden)
+
+	* tcl(Win|Unix|Mac)FCmd.c:
+	* tcl(Win|Unix|Mac)File.c: replaced TclpListVolumes with
+	TclpObjListVolumes with different signature, updated code due to more
+	efficient signature of Tcl_FSGetTranslatedPath. Used cached native
+	paths where possible to improve efficiency -- this was completed on
+	MacOS, but on Unix and Win the traversal functions make the task much
+	more complex, so there are still some improvements possible there.
+	Removed unused TclpNormalizePath which had been left in tclWinFCmd.c.
+	Objectified all 'file attributes' functions. Fixed the new [Bug
+	451571, Bruce Stephens] which is most obvious on Unix, but could occur
+	on MacOS or Windows. This bug actually existed in Tcl 8.3.x but was
+	only made obvious by the recent filesystem overhaul when the code was
+	exercised more heavily.
+	* tests/fileName.test: Three new tests to exercise the above bug, and
+	make sure it is fixed correctly.
+	* unix/tclUnixFile.c: avoid panic in glob when a link doesn't point
+	anywhere. It would probably be good to define exactly what Tcl should
+	do in circumstances like these, and make sure mac/win/unix all behave
+	accordingly. [Bug 417111] (Hemang Lavana). Also fixed
+	misleading/obsolete comment in the code.
+	* generic/tcl.stubs: changed signature of Tcl_FSGetTranslatedPath and
+	added Tcl_FSGetTranslatedStringPath.
+	These changes allow further optimisations in the FS code.
+	* generic/tcl.h: changed signature of Tcl_FSListVolumes so that it
+	doesn't require a Tcl interpreter plus result. Renamed Tcl_FSReadLink
+	to Tcl_FSLink with additional argument so we can support making links
+	in the future. [Patch: 450340]
+	* generic/tclInt.h: added declaration for TclpObjListVolumes.
+	Objectified internal call signatures for 'file attributes' functions,
+	and added an internal objectified get path type function.
+	* generic/tclIOUtil.c: added the moved function TclpListVolumes which
+	calls platform specific code (needed for backwards compatibility), and
+	improved efficiency of parts of the FS (particularly file
+	normalization). Much less copying and memory allocation is required
+	now. added new GetPathType so that changes in 'file volumes' can
+	actually affect files' types, and objectified more code. Made current
+	code work with test suite artificially changing current platform.
+	Added 'static' keywords where required.
+	* generic/tclIO.c:
+	* generic/tclTest.c: Added 'static' keywords, fixing [Bug 453872] (Bob
+	Techentin)
+	* generic/tclCmdAH.c: file command implementation updated for API
+	changes, removed unnecessary special-case SplitPath static function,
+	since it no longer helps prevent code duplication. Moved setting of
+	interpreter result to each individual location that actually required
+	it, to avoid very large code separation between reading and setting
+	the result.
+	* doc/FileSystem.3: updated documentation for the new or changed APIs,
+	and clarified some issues.
+	* doc/SplitPath.3: added pointer to newer APIs in FileSystem.3
+	* doc/filename.n: clarified current implementation of tilde support on
+	Mac/Win.  [Bug 453514] (Sergey Kuzmin)
+	* doc/glob.n: improved documentation for '-directory' and '-path'
+	options.
+
+	There are now many private, obsolete, platform-specific 'Tclp'
+	string-based filesystem APIs which could be removed. We should check
+	whether any of these are used by extensions and, at least in Tcl 9,
+	remove them.
+
+	The above changes signify a ***POTENTIAL INCOMPATIBILITY*** with
+	8.4a3, since signatures of two functions in the new API have changed,
+	but not with older versions of Tcl.
+
+2001-08-23  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclBinary.c (FormatNumber): Extract a long from the object
+	and not an int, to stop [binary format] from being unable to format
+	some input numbers on architectures where sizeof(int) is less than
+	sizeof(long) (particularly Alpha). [tiprender Bug 441861]
+
+	* tests/format.test: Converted conditional execution of tests into a

+	* win/tclWinDde.c (Tcl_DdeObjCmd): added -binary option to dde request
+	command to allow for returning binary data. [Bug 227482]
+	Updated dde to 1.2
+
+	* tests/tcltest.test: added unixExecs constraint to files that used

+	The use of tmpnam in TclpTempFileName must still be changed.
+
+	* tests/http.test (http-4.14): fixed variable error return.
+	[Bug 424252]
+
+2001-08-03  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/configure: regenerated
+	* win/tcl.m4: fixed DLLSUFFIX definition to always be ${DBGX}.dll.
+	This is necessary for TEA compliant builds that build shared against a
+	static-built Tcl.
+	* win/Makefile.in ($(TCLSH)): added $(TCL_STUB_LIB_FILE) to build
+	target, otherwise it wouldn't get generated in a static build.
+
+2001-08-06  Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+	* generic/tclIOCmd.c (Tcl_GetsObjCmd): Applied patch from [Bug 442665]
+	to fix the bug reported by it. The function can corrupt a freed object
+	if it is called with objc == 3. This is because it retrieves resultPtr
+	and does not increment its reference count, but then calls
+	Tcl_ObjSetVar2, which causes the retrieved resultPtr object to be
+	released.
+
+2001-08-06  Don Porter <dgp@users.sourceforge.net>
+
+	* doc/tclsh.1: Added note that the tclsh program is frequently
+	installed with the Tcl version numer as part of the name. [Patch
+	402725]
+
+	* generic/tclPkg.c:
+	* tests/pkg.test:  [package forget] now forgets all of the package
+	arguments it receives, not stopping when a package is not found. [Bug
+	415273]
+
+2001-08-02  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclIOUtil.c (Tcl_FSMatchInDirectory): corrected

+
+2001-08-02  Mo DeJong  <mdejong@redhat.com>
+
+	* generic/tclPlatDecls.h:
+	* win/tclWinPort.h: Revert <tchar.h> related changes made to improve
+	Cygwin support on 2001-07-18. This change ended up breaking the VC++
+	build because of conflicts between Windows APIs and internal Tk APIs.
+
+2001-08-01  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* unix/tclUnixFCmd.c: minor casts to eliminate warnings. (lim)
+	[Patch 440218]
+
+	* tests/parseOld.test: changed some tests that required testwordend to
+	exist to skip in a proper tcltest manner. [Bug 442663]
+
+	* library/http/http.tcl (http::mapReply): the regsub'ing of \n and \t
+	to escape them was unnecessary.

+2001-07-18  Mo DeJong  <mdejong@redhat.com>
+
+	* generic/tclPlatDecls.h: Define TCHAR by including windows.h instead
+	of tchar.h since Cygwin does not support the tchar.h header. Include
+	CHECK_UNICODE_CALLS logic from tclWinPort.h.
+	* win/tclWinPort.h: Remove CHECK_UNICODE_CALLS logic. Remove include

+	* win/tclWinReg.c: Remove duplicate include of windows.h.
+
+2001-07-18  Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+	* generic/tclIO.c: Aftermath to [Bug 427196]. Squash empty buffers if
+	they are smaller than the requested buffersize, to prevent reusage of
+	old buffers and to honor changes in the requested buffersize made by
+	the user.
+
+2001-07-17  Mo DeJong  <mdejong@redhat.com>
+
+	* win/tclWinFile.c (TclpReadlink): Add Cygwin specific definition for
+	the TclpReadlink function. This method implements reading of symbolic
+	links when build with Cygwin.
+
+2001-07-17  Mo DeJong  <mdejong@redhat.com>
+
+	* win/tclWinPort.h: Add Cygwin specific defines for environ and
+	timezone variables.
+
+2001-07-17  Andreas Kupries <andreas_kupries@users.sourceforge.net>
+
+	* generic/tclIO.c (GetInput): Fixed [Bug 427196]. Memory was
+	overwritten because a buffer was used after a change of the requested
+	buffersize together with that requested buffersize and not its actual
+	size, which was smaller. Note that the continous reuse of the smaller
+	buffer negatively impacts performance. The system never allocates a
+	buffer with the newly requested bigger buffersize.
+
+2001-07-16  Mo DeJong  <mdejong@redhat.com>
+
+	* generic/tcl.h: Define __WIN32__ when __CYGWIN__ or __MINGW32__ is
+	defined.
+	* generic/tclAlloc.c: Define caddr_t when compiling with VC++ or
+	mingw. This type is already defined when compiling with Cygwin.
+
+2001-07-16  Mo DeJong  <mdejong@redhat.com>

+	* win/tclWinConsole.c:
+	* win/tclWinPipe.c:
+	* win/tclWinPort.h:
+	* win/tclWinSerial.c:
+	* win/tclWinThrd.c:
+	Remove unnecessary #includes of dos.h, direct.h, and tchar.h. This
+	will help the Cygwin porting effort since these headers do not exist
+	under Cygwin.
+
+2001-07-16  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/tclWinPipe.c (PipeClose2Proc): constrained the mutex lock to
+	just the TerminateThread call and waiting for termination. (jsmith)
+
+	* generic/tclCmdMZ.c: Removed extra copy of the SCAN_* macros
+	#defined in generic/tclScan.c. [Bug 441230] (porter)
+
+2001-07-12  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/unixInit.test (unixInit-2.8): Added extra constraint,
+	notInstalledInTmp, to stop this test from damaging installations in
+	/tmp; not much fun to have to reinstall the Tcl library every time you
+	run the test suite!
+
+	* tests/subst.test (subst-10.*): Updated tests to check new behaviour
+	for 'break' in command substitutions.
+	(subst-1.2,subst-7.1): Error messages changed.
+	* doc/SubstObj.3: New file, to document Tcl_SubstObj.
+	* doc/subst.n: Improved and updated documentation for 'subst' to help
+	support the changed behaviour.
+	* generic/tcl.decls (generic-437): Declaration for Tcl_SubstObj
+	* generic/tcl.h (TCL_SUBST_*): Added flags for Tcl_SubstObj.
+	* generic/tclCmdMZ.c (Tcl_SubstObj,Tcl_SubstObjCmd): Divided into two
+	parts to allow people to access the innards of 'subst' and changed the
+	behaviour when command substitutions do a 'break' to be different from
+	'continue'. Also now works with objects, which allows for some nifty
+	optimisations with variable substitutions and a slight improvement
+	with command substitutions. [TIP#36]
+
+2001-07-10  Mo DeJong  <mdejong@redhat.com>
+
+	* unix/Makefile.in: Add AR variable for use in STLIB_LD.
+	* unix/configure: Regen.
+	* unix/configure.in: Use STLIB_LD when defining MAKE_LIB and
+	MAKE_STUB_LIB. Subst RANLIB and AR.
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Add doc comment about STLIB_LD
+	command. Check ${AR} env var when setting STLIB_LD and delay
+	evaluation until make time.
+	* win/configure: Regen.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Delay evaluation of ${AR} in STLIB_LD
+	and add flags to better match the Unix implementation. Don't bother
+	defining AR when using VC++ since it is not used.
+
+2001-07-06  Mo DeJong  <mdejong@redhat.com>
+
+	* win/configure: Regen.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Pass -e _WinMain@16 in addition to
+	the -mwindows flag to work around a problem with ld when it
+	incorrectly use main() as the executable entry point when both
+	WinMain() and main() are available.
+
+2001-07-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/cmdAH.test: Added leading zero to file modes to work around
+	fault in HPUX strtol() which ignores the base parameter. [Bug 438808]
+
+2001-07-05  Mo DeJong  <mdejong@redhat.com>
+
+	* win/Makefile.in: Subst DEPARG directly instead of relying on a
+	variable. This will make Cygwin builds faster since an extra exec will
+	be avoided.
+	* win/configure: Regen.
+	* win/configure.in: Subst DEPARG.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Move AC_MSG_CHECKING after the
+	AC_CHECK_PROG so that status messages do not get mixed together. Set
+	DEPARG based on the results of the cygpath check so that we avoid
+	using an extra exec when it is not needed. Use ac_cv_cygwin status
+	flag instead of looking at the output of gcc -v, which works in the
+	case where -mno-cygwin is set in the CFLAGS.
+
+2001-07-04  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* README:
+	* mac/README:
+	* unix/README:
+	* win/README:
+	* win/README.binary: updated READMEs with purls
+
+2001-07-03  Mo DeJong  <mdejong@redhat.com>
+
+	* win/Makefile.in: Remove PATHTYPE variable.
+	* win/configure: Regen.
+	* win/configure.in: Don't subst PATHTYPE.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Remove PATHTYPE variable. Set CYGPATH
+	to "cygpath -w" if the cygpath executable is found on the path. This
+	approach works for native Cygwin builds and cross compiles.
+
+2001-07-03  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tests/var.test:
+	* generic/tclVar.c (Tcl_VariableObjCmd): added patch to check for
+	number of args. [Patch 426038]
+
+	* generic/tclVar.c (Tcl_GetVar2Ex): added ability to recognize
+	TCL_TRACE_READS flags to cause creation of part1 in TclLookupVar to
+	make sure newly created array will get read traces triggered
+	appropriately. This is called by Tcl_ObjGetVar2, Tcl_GetVar, and
+	Tcl_GetVar2.
+	(TclSetIndexedScalar, TclSetElementOfIndexedArray): added read trace
+	triggering for lappend case.
+	(Tcl_LappendObjCmd): pass TCL_TRACE_READS to Tcl_ObjGetVar2 to trigger
+	possible read traces for new arrays.
+
+	* generic/tclExecute.c (TclExecuteByteCode): added TCL_TRACE_READS
+	flag to INST_LAPPEND(_ARRAY)_STK case to trigger read traces for newly
+	created arrays. Removed unnecessary #ifdef for TCL_COMPILE_DEBUG in
+	INST_LOAD_SCALAR1 case.
+
+	* tests/append.test:
+	* tests/appendComp.test: added tests for read trace triggering for
+	append and lappend.
+
+2001-07-03  Mo DeJong  <mdejong@redhat.com>
+
+	* tests/clock.test (clock-2.5): Adjust test so that it passes when the
+	time slice is 60 msecs, now passes under Windows 98.
+
+2001-07-03  Mo DeJong  <mdejong@redhat.com>
+
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Don't pass the v flag to ${AR} when
+	using gcc, verbose output is not needed.
+
+2001-07-03  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/unixInit.test (unixInit-2.8):  Changed test back to using
+	installation layout, adding comments explaining why the test writes to
+	the directories it does, and checks to avoid destroying other files in
+	/tmp.
+
+2001-07-03  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/unixInit.test (unixInit-1.2): Fixed faults reported in
+	[Bug 438070] - well, at least enough to work on Solaris - and added
+	comments that should make what is going on in the test clearer.
+
+2001-07-02  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tests/util.test: added util-4.6

+
+2001-07-02  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/unixInit.test (unixInit-2.8):  Corrected test for all absolute
+	pathnames in library path when executable is installed near root

+
+	* tests/unixInit.test (unixInit-2.9):
+	* unix/tclUnixInit.c (TclpInitLibraryPath):
+	* win/tclWinInit.c (TclpInitLibraryPath):  Corrected buggy

+	for bad construction. [Bug 438014]
+
+2001-06-28  Miguel Sofer  <msofer@users.sourceforge.net>

+
+2001-06-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/unixInit.test (unixInit-1.2): Modified so as not to require a
+	local echo service, which fails on many systems which have that turned
+	off for security reasons...
+
+2001-06-27  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclInt.h:
+	* generic/tclObj.c:
+	* unix/Makefile.in: added a -DPURIFY mode that makes Tcl_Obj's
+	allocated and free singularly (instead of in alloc in blocks and never
+	free) to allow checkers like Purify to operate better.
+
+	* library/encoding/koi8-u.enc: added koi8-u (Ukranian variant)
+	encoding.
+
+	* tests/subst.test:
+	* generic/tclUtf.c (Tcl_UtfBackslash): Corrected backslash handling of
+	multibyte utf-8 chars. [Bug 217987]
+
+	* generic/tclCmdIL.c (InfoProcsCmd): fixed potential mem leak in info
+	procs that created objects without using them.
+
+	* generic/tclCompCmds.c (TclCompileStringCmd): fixed mem leak when
+	string command failed to parse the subcommand.
+
+	* doc/interp.n:
+	* doc/unknown.n: updated notes about what is in a safe interp. [Bug

+
+2001-06-27  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/event.test (event-11.5): Removed hard-coded port number which
+	could fail on some systems. [Bug 436727]
+
+2001-06-26  Mo DeJong  <mdejong@redhat.com>
+
+	* unix/Makefile.in:
+	* win/Makefile.in: Add `make shell` target. This target will set the
+	proper env vars before invoking tclsh from the build directory.
+
+2001-06-26  Mo DeJong  <mdejong@redhat.com>
+
+	* win/Makefile.in: Use : to separate VPATH entries. This works for
+	both Cygwin builds and cross builds, the VPSEP variable is simply
+	unneeded complexity.
+	* win/configure: Regen.
+	* win/configure.in: Don't subst VPSEP.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Remove VPSEP variable.
+
+2001-06-26  Mo DeJong  <mdejong@redhat.com>
+
+	* unix/configure: Regen.

+
+2001-06-26  Mo DeJong  <mdejong@redhat.com>
+
+	* unix/configure: Regen.
+	* unix/configure.in: Set CFLAGS to "" if the user did not set CFLAGS
+	in the env. This keeps AC_PROG_CC from adding "-g -O2" to the CFLAGS
+	by default.
+	* win/configure: Regen.
+	* win/configure.in: Ditto.
+
+2001-06-25  Mo DeJong  <mdejong@redhat.com>
+
+	* win/configure: Regen.
+	* win/configure.in: Use RC_DEFINE flag from tcl.m4.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Set RC_DEFINE flag based on the
+	compiler in use.
+
+2001-06-25  Mo DeJong  <mdejong@redhat.com>
+
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Link to the imm32 library when
+	building with mingw gcc.
+
+2001-06-25  Mo DeJong  <mdejong@redhat.com>
+
+	* win/configure: Regen.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): When building with gcc, don't attempt
+	to link with LD or support dllwrap. Simply require a recent version of
+	Cygwin gcc or Mingw gcc that supports -shared. When linking, use gcc
+	instead of ld since gcc automatically includes libs like -lmsvcrt.
+
+2001-06-22  Mo DeJong  <mdejong@redhat.com>
+
+	* win/configure: Regen.

+	* win/tcl.m4: Fix silly typo in last checkin.
+
+2001-06-22  Mo DeJong  <mdejong@redhat.com>
+
+	* unix/Makefile.in: Set CFLAGS to @CFLAGS@ and @CFLAGS_DEFAULT@. Set
+	LDFLAGS to @LDFLAGS@ and @LDFLAGS_DEFAULT@. Add LDFLAGS_DEBUG and
+	LDFLAGS_OPTIMIZE to match the way CFLAGS_DEFAULT works. This will
+	support user set CFLAGS or LDFLAGS at configure time.
+	* unix/configure: Regen.
+	* unix/configure.in: Don't set CFLAGS to CFLAGS_DEFAULT, instead
+	subst CFLAGS_DEFAULT into the Makefile. Add AC_SUBST for
+	CFLAGS_DEFAULT, LDFLAGS_DEFAULT, LDFLAGS_DEBUG, and LDFLAGS_OPTIMIZE.
+	* unix/tcl.m4 (SC_ENABLE_SYMBOLS): Modify LDFLAGS_DEFAULT so that it
+	uses a Makefile variable just like CFLAGS_DEFAULT.
+	* win/Makefile.in: Set CFLAGS to @CFLAGS@ and @CFLAGS_DEFAULT@. Set
+	LDFLAGS to @LDFLAGS@ and @LDFLAGS_DEFAULT@. This will support user set

+
+2001-06-22  Mo DeJong  <mdejong@redhat.com>
+
+	* win/configure:
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Don't set LDFLAGS_DEBUG to -g or
+	LDFLAGS_OPTIMIZE to -O when compiling with gcc. These flags are not
+	needed and can cause problems with the Cygwin version of ld.
+
+2001-06-18  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/unixInit.test (unixInit-1.2,unixInit-2.8): Added test for code
+	described below, and fixed a couple of errors that caused problems
+	during testing; the code to determine the installedTcl constraint was
+	wrong, and test unixInit-2.8 assumed that /tmp/lib was free for use
+	and could be deleted, which clashed nastily with my installation and
+	made other tests fail unnecessarily!
+
+	* unix/tclUnixChan.c (TtyInit,TclpOpenFileChannel,
+	(Tcl_MakeFileChannel,TclpGetDefaultStdChannel): Alterations so that
+	the standard channels - stdin, stdout and stderr - have the correct
+	type and fconfigure options. This required making the initialisation
+	of serial lines a little more sophisticated to make the console behave
+	correctly in interactive mode... [Bug 219137 and duplicates]

+	* generic/tclIO.c: Split of both 'Tcl_ReadChars' and 'Tcl_WriteChars'
+	into a public error checking and an internal working part. The public
+	functions now use the new internal ones. The new functions are

+	lappend, lindex and llength. Refactored set and incr compile commands
+	to use new TclPushVarName function for handling the varname component
+	during compilation (also used by append and lappend). Changed string
+	compile command to compile toplevel code as well (when possible).
+	* generic/tclCompile.c: added new instruction enums
+	* generic/tclCompile.h: added debug info for new instructions
+	* generic/tclExecute.c (TclExecuteByteCode): moved elemPtr to toplevel

+	Refactored repititious code for reuse with INST_LOAD_STK (same as
+	INST_LOAD_SCALAR_STK), INST_STORE_STK (same as INST_STORE_SCALAR_STK).
+	Updated INST_STR_CMP with style of fix of 2001-04-06 Fellows
+	[Bug 219201] as that fix only affected the runtime eval'ed "string"
+	(string compare is normally byte-compiled now). We may want to back
+	these out for speed in the future, noting the problems with \x00
+	comparisons in the docs.
+	* generic/tclInt.h: declarations for new compile commands.
+	* generic/tclVar.c: change TclGetIndexedScalar,
+	TclGetElementOfIndexedArray, TclSetElementOfIndexedArray and

+
+2001-05-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/console.n: Created. It seems very odd to me that the console
+	implementation is part of the Tcl distribution and not part of Tk, but
+	given the location of the source, the documentation must obviously
+	match up...
+
+2001-05-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd):
+	* tests/string.test (string-4.14): Negative string indices should not

+	treated as referring to the start of the string. [Bug 423581]
+
+2001-05-11  Mo DeJong  <mdejong@redhat.com>

+	***POTENTIAL INCOMPATIBILITY*** for any callers of [auto_import] from

+
+2001-05-03  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclParse.c:
+	* tests/namespace.test: Insure consistent behaviour of the [unknown]

+	"unknown" [Patch 421166, Bug 420507]
+
+2001-05-02  Don Porter  <dgp@users.sourceforge.net>

+	* generic/tclTest.c (TestChannelCmd): added cast to mollify Windows
+	debug build.
+
+	* win/tclWinSock.c (SocketEventProc): Fixed race condition in
+	readability of socket on Windows. [Patch 410674, Bug 219205, 219333]
+
+	* win/tcl.m4: added imm32.lib to LIBS_GUI for Tk IME support.
+
+	* win/Makefile.in (install-libraries): removed extra \s that broke

+
+2001-03-30  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* All of the changes below belong to TIP #10 [Tcl I/O Enhancement:
+	Thread-Aware Channels]. See also [Patch 403358] at SF.
+
+	* generic/tclIO.h (struct ChannelState, line 236f): Extended the
+	structure with a new field of type 'Tcl_ThreadId' to hold the id of
+	the thread currently managing all channels with this state.
+
+	Note: This structure is shared by all channels in a stack of
+	transformations.
+
+	* generic/tclIO.c (Tcl_CreateChannel, lines 1058-1065): Modified to
+	store the Id of the current thread in the 'ChannelState' of the new
+	channel.
+
+	* generic/tclIO.c (Tcl_SpliceChannel, lines 2265-2270): Modified in
+	the same manner as 'Tcl_CreateChannel' as the channel will be managed
+	by the current thread afterward.
+
+	* generic/tclIO.c   (Tcl_GetChannelThread, lines 1478-1503):
+	* generic/tcl.decls (Tcl_GetChannelThread, lines 1504-1506): New API
+	function to retrieve the Id of the managing thread from a channel.
+	Implementation and declaration.
+
+	* generic/tclTest.c (TestChannelCmd, lines 4520-4532): Added
+	subcommand 'mthread' to query a channel about its managing thread.
+
+2001-03-29  Mo DeJong  <mdejong@redhat.com>
+
+	* tests/interp.test: Print out warning when testinterpdelete command
+	is not defined. Add tests that checks to make sure a child interp
+	inherits the parent's cwd.
+
+2001-03-29  Jeff Hobbs  <jeffh@gimlet.activestate.com>
+
+	* doc/tcltest.n: corrected incorrect macro usage.
+
+	* doc/lsort.n: corrected unbalanced nroff macros.
+
+	* unix/tclUnixPipe.c (TclpCreateTempFile): prevent potential race
+	condition and security leak in tmp filename creation.
+	[Patch 402924] (max)
+
+	* unix/configure:
+	* unix/tcl.m4: corrected IRIX-5.x config to not use -n32.
+	[Patch 403626] (english)
+
+	* unix/tclUnixThrd.c (Tcl_ConditionWait): fixed handling of timeout
+	for threads (corrects excessive CPU usage issue for Tk on Unix in
+	threaded Tcl environment). [Bug 411603] (ruppert)
+
+2001-03-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/lsort.n: Added some notes that clarify the behaviour of
+	[lsort] as well as a whole bunch of examples.  [Bug 219202]
+
+2001-03-27  Jeff Hobbs  <jeffh@gimlet.activestate.com>
+
+	* doc/Alloc.3: corrected docs to note that Tcl_Attempt* return char
+	*'s, not ints. [Bug 411388]
+
+	* tests/regexp.test (regexp-19.1):
+	* generic/tclCmdMZ.c (Tcl_RegsubObjCmd): fixed handling of nulls in
+	subspec value.
+
+2001-03-26  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclDecls.h (Tcl_InitCustomHashTable):  Correction to patch
+	from 2001-01-18;  tclDecls.h was not generated using 'make genstubs'.
+
+2001-03-26  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* win/tclWinInt.h (tclWinTCharEncoding): Removed as now a static
+	variable in win/tclWin32Dll.c instead.
+
+2001-03-23  Jeff Hobbs  <jeffh@activestate.com>
+
+	* generic/tclVar.c (Tcl_ArrayObjCmd): Corrected retrieval of resultPtr
+	to prevent possible corruption.
+
+	* generic/tclNamesp.c (Tcl_Import): Correctly freed a DString.
+	[Patch 403755] (lavana)
+
+2001-03-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/set-old.test (set-old-7.2): Changed error behaviour of
+	[unset] to agree with documentation, so must change test as well.
+
+2001-03-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/package.tcl (pkg_mkIndex):  Added patch from Vince Darley to
+	make [pkg_mkIndex -verbose] even more verbose. [Bug 219349, Patch
+	403529]
+
+2001-03-13  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/info.n: Improved documentation for [info hostname]. [Bug 403840]
+
+	* generic/tclVar.c (Tcl_UnsetObjCmd): Made command behave as
+	documented [issue remaining from Bug 405769]
+
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): A missing {return TCL_OK;}
+	was causing memory corruption. [Bug 408002]
+
+	* generic/tclExecute.c (TclDeleteExecEnv, GrowEvaluationStack,
+	(TclExecuteByteCode): Added some casts to ClientData that are
+	apparently needed on some architectures.
+
+2001-03-12  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/string.test: Fixed some test numberings and added a test.
+	[Patch 403229]
+
+2001-03-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclVar.c (Tcl_UnsetObjCmd): Rewrote argument parser to avoid
+	a read off the end of the argument array that could occur when
+	executing something like [unset -nocomplain] was executed. Improved
+	the error message given when too few arguments are given (-nocomplain
+	should obviously be *before* --, not after it) and also modified the
+	test suite to take account of that and the documentation to use the
+	same improvement. [Bug 405769]
+
+2001-03-02  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclExecute.c (TclExecuteByteCode): Fixed bug that could pass
+	pointers to freed memory to command implementations, which most
+	obviously caused some weird behaviour with [info level], but could
+	have caused problems with user code and command traces too. [Bug
+	404865, Patch 405436]
+
+2001-02-23  msofer  <msofer@users.sourceforge.net>
+
+	* no changes; fixing up the missing comment in the previous one.
+	Sorry.
+
+2001-02-23  msofer  <msofer@ant.utdt>
+
+	* /cvsroot/tcl/tcl/tests/execute.test: added test for evaluation of an
+	expression in a variable; evals once by compiling, second time using
+	the previous compilation
+
+2001-02-18  Kevin B. Kenny  <kennykb@acm.org>
+
+	* doc/clock.n: Updated documentation to reflect the addition of
+	compat/strftime.c, including the correct formatting of ISO-8601:1988
+	fiscal week number (%V).
+
+2001-02-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclCmdMZ.c (Tcl_SplitObjCmd): Improved efficiency of
+	splitting strings into individual characters by adding hash so that
+	only one Tcl_Obj per character is created. Improves performance of
+	splitting of short strings and makes a huge difference to splitting of
+	long strings, such as is done in the mime package in tcllib. [Bug
+	131523]
+
+2001-01-31  Don Porter  <dgp@users.sourceforge.net>
+
+	* win/makefile.vc (install-libraries):  Corrected misdirected install
+	directory for the msgcat 1.2 package.
+
+2001-01-30  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclIO.c (CopyData): Moved code that updates the count of how
+	many bytes are left to copy. Corrects bug that when writing occurs in
+	the background, the copy loop could be escaped without updating the
+	count, causing CopyData() to try to copy more bytes than the toRead
+	value originally passed to TclCopyChannel(), leading to hangs and
+	misreporting of number of bytes copied. [Bug 118203, Patch 103432]
+
+2001-01-18  Andreas Kupries  <a.kupries@westend.com>
+
+	Everything below belongs together, it fixes [Bug 123153]
+
+	* generic/tcl.h (line 342): A bit more explanation about the default
+	value for TCL_PRESERVE_BINARY_COMPATABILITY.
+
+	* generic/tcl.h (line 1208): Define the macro 'Tcl_InitHashTable' only
+	when TCL_PRESERVE_BINARY_COMPATIBILITY is not set as it kills binary
+	compatibility to 8.3 and earlier versions. This is the main part of
+	the patch/change.
+
+	* generic/tcl.decls (line 1469):
+	* generic/tclHash.c (Tcl_InitHashTable):
+	* generic/tclHash.c (Tcl_InitHashTableEx):
+	* generic/tclObj.c (Tcl_InitObjHashTable): Changed
+	'Tcl_InitHashTableEx' to 'Tcl_InitCustomHashTable'. This change is
+	more of an estethical nature, replacing the ubiquitous 'Ex' suffix
+	with a more meaningful name. The introduced binary incompatibility is
+	deemed acceptable as it is between alpha versions.  Updated callers.
+
+	* doc/Hash.3:
+	* unix/mkLinks: Changed 'Tcl_InitHashTableEx' to
+	'Tcl_InitCustomHashTable'.
+
+2001-01-10  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/winPipe.test (winpipe-1.20):
+	* tests/winDde.test (createChildProcess):
+	* tests/pkgMkIndex.test (pkgtest::createIndex): Removed assumption
+	that paths contain no spaces which causes problems with both [eval]
+	and [open |...] due to the well-known differences between lists and
+	strings. Fixes [Bug 119406]
+
+2001-01-04  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/unixInit.test:
+	* unix/tclUnixInit.c (TclpInitLibraryPath):
+	* win/tclWinInit.c (TclpInitLibraryPath):  Several entries in the
+	library path ($tcl_libPath) are determined relative to the absolute
+	path of the executable. When the executable is installed in or near
+	the root directory of the file system, relative pathnames were being
+	incorrectly generated, and in the worst case, memory access violations
+	were crashing the program. [Bug 119416, Patch 102972]

+
+	* win/makefile.vc: some uses of xcopy swapped to the @$(CPY) macro.
+	Reported by Joe Mistachkin <joe@mistachkin.com>.
+
+2002-12-17  Jeff Hobbs  <jeffh@ActiveState.com>
+

+
+	* generic/tclPipe.c (TclCleanupChildren):
+	* tests/winPipe.test:
+	* win/tclWinPipe.c (Tcl_WaitPid):
+	* win/tclWinTest.c:  Gave Tcl_WaitPid the ability to return a Win32
+	exception code translated into a posix style SIG*. This allows [close]
+	to report "CHILDKILLED" without the meaning getting lost in a
+	truncated exit code. In TclCleanupChildren(), TclpGetPid() had to get
+	moved to before Tcl_WaitPid() as the the handle is removed from the
+	list taking away the ability to get the process id after the wait is
+	done. This shouldn't effect the unix implimentaion unless waitpid is
+	called with a pid of zero, meaning "any". I don't think it is..
+

+
+2002-12-11  Don Porter  <dgp@users.sourceforge.net>

+
+	* generic/tclParseExpr.c (TclParseInteger):  Return 1 for the string

+2002-12-09  Jeff Hobbs  <jeffh@ActiveState.com>

+
+2002-12-08  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/tclWinSock.c (SocketThreadExitHandler, InitSockets):  Check
+	that the tsdPtr is valid before dereferencing as we call it from the
+	exit handler, too [Bug 650353]. Another WSAStartup() loaded version
+	comparison byte swap issue fixed. Although 0x0101 byte swapped is
+	still 0x0101, properly claiming which is major/minor is more correct.

+
+	* generic/tclStubInit.c: regen
+	* generic/tclIntPlatDecls.h: regen
+	* generic/tclInt.decls: added TclWinResetInterface
+
+	* win/tclWin32Dll.c (TclWinResetInterfaces):
+	* win/tclWinInit.c (TclpSetInitialEncodings, WinEncodingsCleanup):
+	add exit handler that resets the encoding information to a state where
+	we can reuse Tcl. Following these changes, it is possible to reuse Tcl
+	(following Tcl_FindExecutable or Tcl_CreateInterp) following a
+	Tcl_Finalize.
+
+	* generic/tclIOUtil.c (TclFinalizeFilesystem): reset statics to their
+	original values on finalize to allow reuse of the library.
+
+2002-12-04  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/tclWinPipe.c: reverted back to -r1.27 due to numerous test
+	failures that need to be resolved first. The idea was good, but the
+	details aren't.
+
+2002-12-04  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/tclWinPipe.c (Tcl_WaitPid):  When a process exits with an
+	exception, pass this notice on to the caller with a SIG* code rather
+	than truncating the exit code and missing the meaning. This allows
+	TclCleanupChildren() to report "CHILDKILLED".
+
+	This has a different behavior than unix in that closing the read pipe
+	to a process sends the SIGPIPE signal which is returned as a SIGPIPE
+	exit status. On windows, we send the process a CTRL_BREAK_EVENT and
+	get back a CONTROL_C_EXIT which is documented to mean a SIGINT which
+	seems wrong as a system, but is the correct exit status.
+
+2002-12-04  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c: fix to redirected 'load' in virtual filesystem
+	for some Unix systems.
+
+	* generic/tclEvent.c: the filesystem must be cleaned up before the
+	encoding subsystem because it needs access to encodings. Fixes crash
+	on exit observed in embedded applications.
+
+	* generic/tclTestObj.c: patch omitted from previous change of
+	2002-11-13
+
+2002-12-03  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclStubLib.c (Tcl_InitStubs): prevent the cached check of
+	tclStubsPtr to allow for repeated load/unload of the Tcl dll by
+	hosting apps. [Bug 615304]
+
+2002-12-03  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/tclAppInit.c (sigHandler): Protect from trying to close a NULL
+	handle.
+
+	* win/tclWinPipe.c (PipeClose2Proc, TclpCreateProcess): Send a real
+	Win32 signal (CTRL_C_EVENT) when the read channel is brought down to
+	alert the child to close on its side. Start the process with
+	CREATE_NEW_PROCESS_GROUP to allow the ability to send these signals.
+	The following test case now brings down the child without the use of
+	an external [kill] command.
+
+	% set p [open "|[info name]" w+]
+	file8d5380
+	% pid $p
+	2876
+	% close $p     <- now doesn't block in Tcl_WaitPid()
+	%
+
+	* win/tclWinPipe.c (PipeClose2Proc): Changed CTRL_C_EVENT to
+	CTRL_BREAK_EVENT as it can't be ignored by the child and proved to
+	work on [open "|netstat 1" w+] where CTRL_C_EVENT didn't.
+
+2002-11-27  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/tclWinPort.h: Don't turn off winsock prototypes!  TclX didn't
+	like it. Even though the core doesn't use the prototypes, do offer
+	them.
+
+	* win/tclWinSock.c: Removed shutdown() from the function table as it
+	wasn't referenced anywhere and cleaned-up some casting that that
+	wasn't needed.
+
+	* win/tclWinSock.c: WSAStartup() loaded version comparison error which
+	resulted in 2.0 looking less than 1.1.
+
+	* win/tclWinChan.c (Tcl_MakeFileChannel): return of DuplicateHandle()
+	incorrectly used. [Bug 618852]
+
+2002-11-26  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclEncoding.c (TclFinalizeEncodingSubsystem): properly
+	cleanup all encodings by using Tcl_FirstHashEntry in the while loop.
+
+	* unix/Makefile.in (valgrind): add simple valgrind target
+
+	* tests/exec.test: unset path var to allow singleproc testing
+
+	* generic/tclInterp.c (AliasCreate): preserve/release interps to
+	prevent possible FMR error in bad alias cases.
+
+2002-11-26  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/tclWinPort.h:
+	* win/tclWinSock.c:  This patch does two things:
+
+	1) Cleans-up the winsock typedefs by using the typedefs provided by
+	winsock2.h. This has no effect on how winsock is initialized; just
+	makes the source code easier to read. [Patch 561305 561301]
+
+	2) Revamps how the socket message handler thread is brought up and
+	down to allow for cleaner exits without the use of TerminateThread().
+	TerminateThread is evil. No attempt has been made to resolve [Bug
+	593810] which may need a new channel driver version for adding a
+	registering function within the transfered thread to init the handler
+	thread. IOW, initialization of the TSD structure is getting bypassed
+	through the thread extension's [thread::transfer] command.
+
+2002-11-26  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/tclWinConsole.c:
+	* win/tclWinPipe.c:
+	* win/tclWinSerial.c:
+	* win/tclWinSock.c:
+	* win/tclWinThrd.c:
+	* win/tclWinTime.c:  General cleanup of all worker threads used by the
+	channel drivers. Eliminates the normal case where the worker thread is
+	terminated ('cept the winsock one). Instead, use kernel events to
+	signal a clean exit. Only when the worker thread is blocked on an I/O
+	call is the thread terminated. Essentially, this makes all other
+	channel worker threads behave like the PipeReaderThread() function for
+	it's cleaner exit behavior. This appears to fix [Bug 597924] but needs
+	3rd party confirmation to close the issue.
+
+2002-11-26  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/README: Update msys build env URL. This release #4 build both
+	tcl and tk without problems.
+
+2002-11-22  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* library/init.tcl:         code cleanup to reduce use of
+	* library/opt/optparse.tcl: string compare
+
+	* tests/interp.test: interp-14.4
+	* generic/tclInterp.c (TclPreventAliasLoop): prevent seg fault when
+	creating an alias command over the interp name. [Bug 641195]
+
+2002-11-18  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclUtil.c (SetEndOffsetFromAny): handle integer offset
+	after the "end-" prefix.
+
+	* generic/get.test:
+	* generic/string.test:
+	* generic/tclObj.c (SetIntFromAny, SetWideIntFromAny):
+	* generic/tclGet.c (TclGetLong, Tcl_GetInt): simplify sign handling
+	before calling strtoul(l). [Bug 634856]
+
+2002-11-18  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/tclWinThrd.c (Tcl_CreateThread/TclpThreadExit): Fixed improper
+	compiler macros that missed the VC++ compiler. This resulted in VC++
+	builds using CreateThread()/ExitThread() in place of the proper
+	_beginthreadex()/_endthreadex(). This was a large error and am
+	surprised I missed seeing it earlier.
+
+2002-11-13  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/regexpComp.test: added tests 22.*
+	* generic/tclCompCmds.c (TclCompileRegexpCmd): add left and right
+	anchoring (^ and $) recognition and check starting or ending .* to
+	extend the number of REs that can be compiled to string match or
+	string equal.
+
+2002-11-13  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c:
+	* tests/trace.test: applied patch from Hemang Levana to fix [Bug
+	615043] in execution traces with 'return -code error'.
+
+	* generic/tclTestObj.c:
+	* tests/stringObj.test: added 'knownBug' test for [Bug 635200]
+	* generic/tclStringObj.c: corrected typos in comments
+
+	* generic/tclFileName.c:
+	* tests/fileName.test: applied patch for bug reported against tclvfs
+	concerning handling of Windows serial ports like 'com1', 'lpt3' by the
+	virtual filesystem code.
+
+	* doc/RegExp.3: clarification of the 'extendMatch' return values.
+
+2002-11-11  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclUtil.c (Tcl_Backslash): use TclUtfToUniChar.
+	(Tcl_StringCaseMatch): use TclUtfToUniChar and add further
+	optimizations for the one-byte/char case.
+
+	* generic/tclUtf.c: make use of TclUtfToUniChar macro throughout the
+	functions, and add extra optimization to Tcl_NumUtfChars for
+	one-byte/char case.
+
+	* generic/tclVar.c (DisposeTraceResult, CallVarTraces): add proper
+	static declarations.
+
+	* generic/tclStringObj.c (Tcl_GetCharLength): optimize for the ascii
+	char case.
+	(Tcl_GetUniChar): remove unnecessary use of Tcl_UtfToUniChar.
+	(FillUnicodeRep): Use TclUtfToUniChar.
+
+	* generic/tclHash.c (HashStringKey): move string++ lower to save an
+	instruction.
+
+	* generic/tclExecute.c (TclExecuteByteCode): improve INST_STR_CMP to
+	use memcmp in the one-byte/char case, also use direct index for
+	INST_STR_INDEX in that case.
+
+	* generic/tclEncoding.c (UtfToUtfProc, UtfToUnicodeProc):
+	(TableFromUtfProc, EscapeFromUtfProc): Use TclUtfToUniChar.
+	(UnicodeToUtfProc, TableToUtfProc): add 1-byte char optimizations for
+	Tcl_UniCharToUtf call. These improve encoded channel conversion speeds
+	by up to 20%.
+
+	* tests/split.test: added 1-char string split tests
+	* generic/tclCmdMZ.c (Tcl_SplitObjCmd): Use TclUtfToUniChar. Also
+	added a special case for single-ascii-char splits.
+	(Tcl_StringObjCmd): Use TclUtfToUniChar. For STR_RANGE, support
+	getting ranges of ByteArrays (reverts change from 2000-05-26).
+	(TraceExecutionProc) add proper static declaration.
+
+	* generic/tclInt.h: add macro version of Tcl_UtfToUniChar
+	(TclUtfToUniChar) that does the one-byte utf-char check without
+	calling Tcl_UtfToUniChar, for use by the core. This brings notable
+	speedups for primarily ascii string handling.
+
+	* generic/tcl.h (TCL_PATCH_LEVEL): bump to 8.4.1.1 for patchlevel
+	only. This interim number will only be reflected by [info patchlevel].
+
+2002-11-11  Kevin Kenny  <kennykb@acm.org>
+
+	* doc/Tcl.n: Corrected indentation of the new language. Oops.
+
+2002-11-10  Kevin Kenny <kennykb@acm.org>
+
+	* doc/Tcl.n: Added language to the Endekalogue to make it clear that

+
+	* changes: Note TclInExit TclInThreadExit changes.

+
+	* unix/configure: Regen.

+
+2002-11-03  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclAppInit.c:  Calls Registry_Init() and Dde_Init() when
+	STATIC_BUILD and TCL_USE_STATIC_PACKAGES macros are set.
+
+	* win/makefile.vc:
+	* win/rules.vc:  linkexten option now sets the TCL_USE_STATIC_PACKAGES
+	macro which also adds the registry and dde object files to the link
+	of the shell. [Patch 479697] Also factored some additional macros that
+	will be helpful for extension authors. Version grepping of tcl.h will
+	need to be added to complete this.
+
+	* win/buildall.vc.bat: Added more descriptive commentary.
+
+2002-11-01  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinReg.c:  Changed the Tcl_PkgProvide() line to declare the

+
+2002-10-29  Vince Darley  <vincentdarley@users.sourceforge.net>

+	* win/tclWinInt.h:
+	* win/tclWin32Dll.c: added comments about certain NULL function
+	pointers which will be filled in when Tcl_FindExecutable is called, so
+	that users don't report invalid bugs on this topic. (No code changes

+
+2002-10-26  David Gravereaux <davygrvy@pobox.com>
+
+	* win/makefile.vc: xcopy on NT 4.0 doesn't support the /Y switch

+
+	* generic/tclInt.h: Removed definitions of obsolete HistoryEvent and

+
+2002-10-22  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/StringObj.3, doc/Object.3: Documented that Tcl_Obj's standard
+	string form is a modified UTF-8; apparently, this was not mentioned
+	anywhere in the main docs, and lead to [Bug 624919].
+
+2002-10-21  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/Tcl.pbproj/project.pbxproj: bumped version to 8.4.1

+
+2002-09-29  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclAppInit.c: Added proper exiting conditions using Win32
+	console signals. This handles the existing lack of a Ctrl+C exit to
+	call exit handlers when built for thread support. Also, properly

+	exit handlers will be called. [Bug 219355]

+	* generic/tclPlatDecls.h (TCHAR): Define for Cygwin.
+	* win/tclWinPort.h (putenv, TclpSysAlloc, TclpSysFree,
+	(TclpSysRealloc): Define for Cygwin.
+
+2002-09-26  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/Makefile: preserve environment value of INSTALL_ROOT. When
+	embedding only use deployment build. Force relink before embedded
+	build to ensure new linker flags are picked up.
+
+	* macosx/Tcl.pbproj/project.pbxproj: add symbolic links to debug lib,
+	stub libs and tclConfig.sh in framework toplevel. Configure target
+	dependency fix. Fix to 'clean' action. Added private tcl headers to

+	Thanks to 'CoderX2' on the chat for bringing this to my attention...

+	appropriate moment. I believe this is the cause of [Bug 613117]
+
+	* doc/lset.n: Changed 'list' to 'varName' for consistency with lappend
+	documentation. Thanks to Glenn Jackman [Bug 611719]
+
+2002-09-22  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl:  Corrected [puts -nonewline] within

+
+	* win/coffbase.txt: Added BLT to the virtual base address listings

+	* mac/tclMacApplication.r:
+	* mac/tclMacLibrary.r:

+
+2002-09-10  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/README: Add note about building extensions with the same

+
+	* macosx/Tcl.pbproj/project.pbxproj: disabled building html
+	documentation during embedded build.
+
+2002-09-10  Daniel Steffen  <das@users.sourceforge.net>

+
+	* unix/configure:
+	* unix/tcl.m4: added 64-bit gcc compilation support on HP-11.

+	checkmem commands are initialized in non-safe slave interpreters when
+	TCL_MEM_DEBUG is used. [Bug 583445]
+
+	* win/tclWinConsole.c (ConsoleCloseProc): only wait on writable pipe
+	if there was something to write. This may prevent infinite wait on
+	exit.
+
+	* tests/exec.test: marked exec-18.1 unixOnly until the Windows
+	incompatability (in the test, not the core) can be resolved.
+
+	* tests/http.test (http-3.11): added close $fp that was causing an
+	error on Windows because the file was not closed before deleting.
+
+	* unix/tclUnixInit.c (Tcl_MacOSXGetLibraryPath): made this static
+	function only appear when HAVE_CFBUNDLE is defined.
+
+2002-08-31  Daniel Steffen  <das@users.sourceforge.net>

+
+	*** macosx-8-4-branch merged into the mainline [Patch 602770] ***
+
+	* generic/tcl.decls: added new macosx specific entry to stubs table.
+
+	* tools/genStubs.tcl: added generation of platform guards for
+	macosx. This is a little more complex than it seems, because MacOS X
+	IS "unix" plus a little bit, for the purposes of Tcl. BUT
+	unfortunately, Tk uses "unix" to mean X11. So added platform keys for
+	macosx (the little added to "unix"), "aqua" and "x11" to distinguish
+	these for Tk.
+
+	* generic/tcl.h: added a #ifnded RESOURCE_INCLUDED so that tcl.h can
+	be passed to the resource compiler.
+
+	* generic/tcl.h:
+	* generic/tclNotify.c: added a few Notifier procs, to be able to
+	modify more bits of the Tcl notifier dynamically. Required to get Mac
+	OS X Tk to live on top of the Tcl Unix threaded notifier. Changes the
+	size of the Tcl_NotifierProcs structure, but doesn't move any elements
+	around.
+
+	* unix/tclUnixNotfy.c: moved the call to Tcl_ConditionNotify till
+	AFTER we are done mucking with the pointer swap. Fixes cases where the
+	thread waiting on the condition wakes & accesses the waitingListPtr
+	before it gets reset, causing a hang.
+
+	* library/auto.tcl (tcl_findLibrary): added checking the directories
+	in the tcl_pkgPath for library files on macosx to enable support of
+	the standard Mac OSX library locations.
+
+	* unix/Makefile.in:
+	* unix/configure.in:
+	* unix/tcl.m4: added MAC_OSX_DIR. Added PLAT_OBJS to the OBJS: there
+	are some MacOS X specific files now for Tcl, and when I get the
+	resource & applescript stuff ported over, and restore support for
+	FindFiles, etc, there will be a few more. Added LD_LIBRARY_PATH_VAR
+	configure variable to avoid having to set all possible LD_LIBRARY_PATH
+	analogues on all platforms. LD_LIBRARY_PATH_VAR is "LD_LIBRARY_PATH"
+	by default, "LIBPATH" on AIX, "SHLIB_PATH" on HPUX and
+	"DYLD_LIBRARY_PATH" on Mac OSX. Added configure option to package Tcl
+	as a framework on Mac OSX.
+
+	* macosx/tclMacOSXBundle.c (new): support for finding Tcl extension
+	packaged as 'bundles' in the standard Mac OSX library locations.
+
+	* unix/tclUnixInit.c: added support for findig the tcl script library
+	inside Tcl packaged as a framework on Mac OSX.
+
+	* macosx/Tcl.pbproj/jingham.pbxuser (new):
+	* macosx/Tcl.pbproj/project.pbxproj (new): project for Apple's
+	ProjectBuilder IDE.
+
+	* macosx/Makefile (new): simple makefile for building the project from
+	the command line via the ProjectBuilder tool 'pbxbuild'.

+	<msofer@users.sourceforge.net>.
+
+2002-08-28  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tclEnv.c:
+	* unix/configure.in:
+	* win/tclWinPort.h:  putenv() on some systems copies the buffer rather
+	than taking reference to it. This causes memory leaks and is know to
+	effect mswindows (msvcrt) and NetBSD 1.5.2 . This patch tests for this
+	behavior and turns on -DHAVE_PUTENV_THAT_COPIES=1 when approriate.
+	Thanks to David Welton for assistance. [Bug 414910]
+
+	* unix/configure: regen'd
+
+2002-08-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/eval.n: Added mention of list command and corrected "SEE ALSO".
+
+	* unix/configure.in: Cache handling of ac_cv_type_socklen_t was wrong.
+	[Bug 600931] reported by John Ellson. Fixed by putting the brackets
+	where they belong.
+
+2002-08-26  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompCmds.c: fix for [Bug 599788] (error in element name
+	causing segfault), reported by Tom Wilkason. Fixed by copying the
+	tokens instead of the source string.
+
+2002-08-26  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclThreadAlloc.c: small optimisation, reducing the new
+	allocator's overhead.
+
+2002-08-23  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclObj.c (USE_THREAD_ALLOC): fixed leak [Bug 597936]. Thanks
+	to Zoran Vasiljevic.
+
+2002-08-23  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclThreadAlloc.c (USE_THREAD_ALLOC): moving objects between

+
+2002-08-22  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclBasic.c:
+	* generic/tclCmdMZ.c: fix for freed memory r/w in delete traces [Bug
+	589863], patch by Hemang Lavana.
+
+2002-08-20  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* win/Makefile.in (CFLAGS):
+	* unix/Makefile.in (MEM_DEBUG_FLAGS): Added usage of @MEM_DEBUG_FLAGS@.
+	* win/configure.in:
+	* unix/configure.in: Added usage of SC_ENABLE_MEMDEBUG.
+	* win/tcl.m4:
+	* unix/tcl.m4: Added macro SC_ENABLE_MEMDEBUG. Allows a user of
+	configure to (de)activate memory validation and debugging
+	(TCL_MEM_DEBUG). No need to modify the makefile anymore.
+
+2002-08-20  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclCkalloc.c:	CONSTified MemoryCmd and CheckmemCmd.
+
+	* README:		Bumped version number to 8.4b3 to distinguish

+	* win/configure:
+
+	* library/http/http.tcl:	Corrected installation directory of
+	* library/msgcat/msgcat.tcl:	the package tcltest 2.2. Added
+	* library/opt/optparse.tcl:	comments in other packages to remind
+	* library/tcltest/tcltest.tcl:	that installation directories need
+	* unix/Makefile.in:		updates to match increasing version
+	* win/Makefile.in:		numbers. [Bug 597450]

+
+2002-08-19  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* unix/tclUnixTest.c (TestfilehandlerCmd): Changed readable/writable
+	to the more common readable|writable. Fixes [Bug 596034] reported by
+	Larry Virden <lvirden@users.sourceforge.net>.
+
+2002-08-16  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/fCmd.test: Added test to make sure that the cause of the
+	problem is detectable with an unpatched Tcl.
+	* doc/ObjectType.3: Added note on the root cause of this problem to
+	the documentation, since it is possible for user code to trigger this
+	sort of behaviour too.
+	* generic/tclIOUtil.c (SetFsPathFromAny): Objects should only have
+	their old representation deleted when we know that we are about to
+	install a new one. This stops a weird TclX bug under Linux with
+	certain kinds of memory debugging enabled which essentally came down
+	to a double-free of a string.
+
+2002-08-14  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclInt.h:
+	* generic/tclObj.c: (code cleanup) factored the parts in the macros
+	TclNewObj() / TclDecrRefCount() into a common part for all
+	memory allocators and two new macros TclAllocObjStorage() /
+	TclFreeObjStorage() that are specific to each allocator and fully
+	describe the differences. Removed allocator-specific code from
+	tclObj.c by using the macros.
+
+2002-08-12  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c: fixing UMR in delete traces, [Bug 589863].
+
+2002-08-08  David Gravereaux <davygrvy@pobox.com>
+
+	* tools/man2help.tcl: Fixed $argv handling bug where if -bitmap wasn't
+	specified $argc was off by one.
+
+2002-08-08  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* tests/uplevel.test: added 6.1 to test [uplevel] with shadowed
+	commands [Bug 524383]
+
+	* tests/subst.test: added 5.8-10 as further tests for [Bug 495207]
+
+2002-08-08  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/README: Noted removal of defs.tcl.
+
+2002-08-08  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* doc/lsearch.n: corrected lsearch docs to use -inline in examples.
+
+	*** 8.4b2 TAGGED FOR RELEASE ***
+
+	* tests/fCmd.test:
+	* tests/unixFCmd.test: updated tests for new link copy behavior.
+	* generic/tclFCmd.c (CopyRenameOneFile): changed the behavior to
+	follow links to endpoints and copy that file/directory instead of just
+	copying the surface link. This means that trying to copy a link that
+	has no endpoint (danling link) is an error. [Patch 591647] (darley)
+	(CopyRenameOneFile): this is currently disabled by default until
+	further issues with such behavior (like relative links) can be
+	handled correctly.
+
+	* tests/README: slight wording improvements
+
+2002-08-07  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* docs/BoolObj.3: added description of valid string reps for a
+	boolean object. [Bug 584794]
+	* generic/tclObj.c: optimised Tcl_GetBooleanFromObj and
+	SetBooleanFromAny to avoid parsing the string rep when it can be
+	avoided. [Bugs 584650, 472576]
+
+2002-08-07  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompile.h:
+	* generic/tclObj.c: making tclCmdNameType static ([Bug 584567], Don
+	Porter).
+
+2002-08-07  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclObj.c (Tcl_NewObj): added conditional code for
+	USE_THREAD_ALLOC; objects allocated through Tcl_NewObj() were
+	otherwise being leaked. [Bug 587488] reported by Sven Sass.
+
+2002-08-06  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclInt.decls:
+	* unix/tclUnixThrd.c: Added stubs and implementations for
+	non-threaded build for the tclUnixThrd.c procs TclpReaddir,
+	TclpLocaltime, TclpGmtime and TclpInetNtoa. Fixes link errors in
+	stubbed & threaded extensions that include tclUnixPort.h and use any
+	of the procs readdir, localtime, gmtime or inet_ntoa (e.g. TclX 8.4)
+	[Bug 589526]
+	* generic/tclIntPlatDecls.h:
+	* generic/tclStubInit.c: Regen.
+
+2002-08-05  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl:	The setup and cleanup scripts are now
+	* library/tcltest/pkgIndex.tcl:	skipped when a test is skipped, fixing
+	* tests/tcltest.test:		[Bug 589859]. Test for bug added, and
+	corrected tcltest package bumped to version 2.2.
+
+	* generic/tcl.decls:	Restored Tcl_Concat to return (char *). Like
+	* generic/tclDecls.h:	Tcl_Merge, it transfers ownership of a dynamic
+	* generic/tclUtil.c:	allocated string to the caller.
+
+2002-08-04  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/CmdCmplt.3:	Applied Patch 585105 to fully CONST-ify all
+	* doc/Concat.3:		remaining public interfaces of Tcl. Notably,
+	* doc/CrtCommand.3:	the parser no longer writes on the string it
+	* doc/CrtSlave.3:	is parsing, so it is no longer necessary for
+	* doc/CrtTrace.3:	Tcl_Eval() to be given a writable string. Also
+	* doc/Eval.3:		the refactoring of the Tcl_*Var* routines by
+	* doc/ExprLong.3:	by Miguel Sofer is included, so that the
+	* doc/LinkVar.3:	"part1" argument for them no longer needs to
+	* doc/ParseCmd.3:	be writable either.
+	* doc/SetVar.3:
+	* doc/TraceVar.3:
+	* doc/UpVar.3:		Compatibility support has been enhanced so
+	* generic/tcl.decls:	that a #define of USE_NON_CONST will remove
+	* generic/tcl.h:	all possible source incompatibilities with the
+	* generic/tclBasic.c:	8.3 version of the header file(s). The new
+	* generic/tclCmdMZ.c:	#define of USE_COMPAT_CONST now does what
+	* generic/tclCompCmds.c:USE_NON_CONST used to do -- disable only those
+	* generic/tclCompExpr.c:new CONST's that introduce irreconcilable
+	* generic/tclCompile.c:	incompatibilities.
+	* generic/tclCompile.h:
+	* generic/tclDecls.h:	Several bugs are also fixed by this patch.
+	* generic/tclEnv.c:	[Bugs 584051,580433] [Patches 585105,582429]

+2002-08-01  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c: bugfix (reading freed memory). Testsuite
+	passed on linux/i386, compile-13.1 hung on linux/alpha.
+
+2002-08-01  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c: added a reference count for the complete
+	execution stack, instead of Tcl_Preserve/Tcl_Release.
+
+2002-08-01  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclCkalloc.c (TclFinalizeMemorySubsystem): Don't lock the
+	ckalloc mutex before invoking the Tcl_DumpActiveMemory function since
+	it also locks the same mutex. This code is only executed when "memory
+	onexit filename" has been executed and Tcl is compiled with
+	-DTCL_MEM_DEBUG.
+
+2002-08-01  Reinhard Max  <max@suse.de>
+
+	* win/tclWinPort.h: The windows headers don't provide socklen_t, so we
+	have to do it.
+
+2002-07-31  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclInt.h (USE_THREAD_ALLOC): for unshared objects,
+	TclDecrRefCount now frees the internal rep before the string rep -
+	just like the non-macro Tcl_DecrRefCount/TclFreeObj [Bug 524802]. For
+	the other allocators the fix was done on 2002-03-06.
+
+2002-07-31  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclInterp.c: signed/unsigned comparison warning fixed
+	(Vince Darley).
+
+2002-07-31  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* unix/tcl.m4 (SC_BUGGY_STRTOD): Enabled caching of test results.
+
+	* unix/tcl.m4 (SC_BUGGY_STRTOD): Solaris 2.8 still has a buggy
+	strtod() implementation; make sure we detect it.
+
+	* tests/expr.test (expr-22.*): Marked as non-portable because it seems
+	that these tests have an annoying tendency to fail in unexpected ways.
+	[Bugs 584825, 584950, 585986]
+
+2002-07-30  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* tests/io.test:
+	* generic/tclIO.c (WriteChars): Added flag to break out of loop if
+	nothing of the input is consumed at all, to prevent infinite looping
+	of called with a non-UTF-8 string. Fixes Bug 584603 (partially). Added
+	new test "io-60.1". Might need additional changes to Tcl_Main so that
+	unprintable results are printed as binary data.
+
+2002-07-29  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/Makefile.in: Use CC_SEARCH_FLAGS instead of LD_SEARCH_FLAGS
+	when linking with ${CC}.
+	* unix/configure: Regen.
+	* unix/configure.in: Don't subst CC_SEARCH_FLAGS or LD_SEARCH_FLAGS
+	since this is now done in tcl.m4.
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Document and set CC_SEARCH_FLAGS
+	whenever LD_SEARCH_FLAGS is set. [Patch 588290]
+
+2002-07-29  Reinhard Max  <max@suse.de>
+
+	* unix/tcl.m4 (SC_SERIAL_PORT): Fixed detection for cases when
+                                        configure's stdin is not a tty.
+
+	* unix/tclUnixPort.h:
+	* generic/tclIOSock.c:          Changed size_t to socklen_t in
+                                        socket-related function calls.
+
+	* unix/configure.in:            Added test and fallback definition
+                                        for socklen_t.
+
+	* unix/configure:               generated.
+
+2002-07-29  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclObj.c: fixed a comment
+
+	* generic/tcl.h:
+	* generic/tclBasic.c:
+	* generic/tclInterp.c: added the new flag TCL_EVAL_INVOKE to the
+	interface of the Tcl_Eval* functions, removing the
+	TCL_EVAL_NO_TRACEBACK added yesterday: alias invocations not only
+	require no tracebacks, but also look up the command name in the global
+	scope - see new test interp-9.4
+	* tests/interp.test: added 9.3 to test for safety of aliases to hidden
+	commands, 9.4 to test for correct command lookup scope.
+
+2002-07-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/regc_locale.c (cclass): [[:xdigit:]] is only a defined
+	concept on western characters, so should not allow any unicode digit,
+	and hence number of ranges in [[:xdigit:]] is fixed.
+	* tests/reg.test: Added test to detect the bug.
+	* generic/regc_cvec.c (newcvec): Corrected initial size value in
+	character vector structure. [Bug 578363] Many thanks to
+	pvgoran@users.sf.net for tracking this down.
+
+2002-07-28  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tcl.h:
+	* generic/tclBasic.c: added the new flag TCL_EVAL_NO_TRACEBACK to the
+	interface of the Tcl_Eval* functions. Modified the error message for
+	too many nested evaluations.
+	* generic/tclInterp.h: changed the Alias struct to be of variable
+	length and store the prefix arguments directly (instead of a pointer
+	to a Tcl_Obj list). Made AliasObjCmd call Tcl_EvalObjv instead of
+	TclObjInvoke - thus making aliases trigger execution traces [Bug
+	582522].
+	* tests/interp.test:
+	* tests/stack.test: adapted to the new error message.
+	* tests/trace.test: added tests for aliases firing the exec traces.
+
+2002-07-27  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/Makefile.in: Revert fix for Tcl bug 529801 since it was
+	incorrect and broke the build on other systems. Fix [Bug 587299]. Add
+	MAJOR_VERSION, MINOR_VERSION, PATCH_LEVEL, SHLIB_LD_FLAGS,
+	SHLIB_LD_LIBS, CC_SEARCH_FLAGS, LD_SEARCH_FLAGS, and LIB_FILE
+	variables to support more generic library build/install rules.
+	* unix/configure: Regen.
+	* unix/configure.in: Move AC_PROG_RANLIB into tcl.m4. Move shared
+	build test and setting of MAKE_LIB and MAKE_STUB_LIB into tcl.m4. Move
+	subst of a number of variables into tcl.m4 where they are defined.
+	* unix/tcl.m4 (SC_ENABLE_SYMBOLS, SC_CONFIG_CFLAGS): Subst vars where
+	they are defined. Add MAKE_LIB, MAKE_STUB_LIB, INSTALL_LIB, and
+	INSTALL_STUB_LIB rules to deal with the ugly details of running ranlib
+	on static libs at build and install time. Replace TCL_SHLIB_LD_EXTRAS
+	with SHLIB_LD_FLAGS and use it when building a shared library.
+	* unix/tclConfig.sh.in: Add TCL_CC_SEARCH_FLAGS.
+
+2002-07-26  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c: fixed Tcl_Obj leak in code corresponding to

+
+2002-07-26  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclVar.c (TclObjLookupVar): leak fix and improved comments.
+
+2002-07-26  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclVar.c (TclLookupVar): removed early returns that
+	prevented the parens from being restored. Also removed goto label as
+	it was not necessary.
+
+2002-07-24  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c:

+	* tests/unixInit.test: relaxed unixInit-3.1 to accept iso8859-15 as a
+	valid C encoding. [Bug 575336]
+
+2002-07-24  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c: restoring the tcl_traceCompile functionality
+	while I repair tcl_traceExec. The core now compiles and runs also
+	under TCL_COMPILE_DEBUG, but execution in the bytecode engine can
+	still not be traced.
+
+2002-07-24  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/Makefile.in:
+	* unix/configure.in: corrected fix for [Bug 529801]: ranlib only
+	needed for static builds on Mac OS X.
+	* unix/configure: Regen.
+	* unix/tclLoadDyld.c: fixed small bugs introduced by Vince,
+	implemented library unloading correctly (needs OS X 10.2).

+2002-07-23  Joe English  <jenglish@users.sourceforge.net>
+
+	* doc/OpenFileChnl.3: (Updates from Larry Virden)
+	* doc/open.n:

+
+2002-07-23  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/configure: Regen.
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Enable 64 bit compilation when using

+
+2002-07-23  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/Makefile.in: Combine ranlib tests and avoid printing unless
+	ranlib is actually run.
+
+2002-07-23  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/tcl.m4 (SC_PATH_X): Set XINCLUDES to "" instead of "# no
+	special path needed" or "# no include files found" when x headers
+	cannot be located.
+
+2002-07-22  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c: made tclNativeFilesystem static (since 07-19
+	changes removed its usage elsewhere), and added comments about its
+	usage.
+	* generic/tclLoad.c:
+	* generic/tcl.h:
+	* generic/tcl.decls:
+	* doc/FileSystem.3: converted last load-related ClientData parameter
+	to Tcl_LoadHandle opaque structure, removing a couple of casts in the
+	process.
+
+	* generic/tclInt.h: removed tclNativeFilesystem declaration since it
+	is now static again.
+
+2002-07-22  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/expr.test (expr-22.*): Added tests to help detect the
+	corrected handling.
+	* generic/tclExecute.c (IllegalExprOperandType): Improved error
+	message generated when attempting to manipulate Inf and NaN values.
+	* generic/tclParseExpr.c (GetLexeme): Allowed parser to recognise
+	'Inf' as a floating-point number. [Bug 218000]
+
+2002-07-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* tclIOUtil.c: Silence compiler warning. [Bug 584408].
+
+2002-07-19  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c: fix to GetFilesystemRecord

+
+2002-07-19  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/configure:
+	* unix/configure.in:
+	* win/configure:
+	* win/configure.in: Add AC_PREREQ(2.13) in an attempt to make it more
+	clear that the configure scripts must be generated with autoconf
+	version 2.13. [Bug 583573]
+
+2002-07-19  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* unix/Makefile.in: fix to build on MacOS X [Bug 529801], bug report
+	and fix from jcw.
+
+2002-07-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* win/tclWinSerial.c (no_timeout): Made this variable static.
+
+	* generic/tclExecute.c, generic/tclCompile.c, generic/tclBasic.c:
+	* generic/tclCompile.h (builtinFuncTable, instructionTable): Added
+	prefix to these symbols because they are visible outside the Tcl
+	library.
+
+	* generic/tclCompExpr.c (operatorTable):
+	* unix/tclUnixTime.c (tmKey):
+	* generic/tclIOUtil.c (theFilesystemEpoch, filesystemWantToModify,
+	filesystemIteratorsInProgress, filesystemOkToModify): Made these
+	variables static.
+
+	* unix/tclUnixFile.c:		Renamed nativeFilesystem to
+	* win/tclWinFile.c:		tclNativeFilesystem and declared
+	* generic/tclIOUtil.c:		it properly in tclInt.h
+	* generic/tclInt.h:
+
+	* generic/tclUtf.c (totalBytes): Made this array static and const.
+
+	* generic/tclParse.c (typeTable): Made this array static and const.
+	(Tcl_ParseBraces): Simplified error handling case so that scans are
+	only performed when needed, and flags are simpler too.
+
+	* license.terms: Added AS to list of copyright holders; it's only
+	fair for the current gatekeepers to be listed here!
+
+	* tests/cmdMZ.test: Renamed constraint for clarity. [Bug 583427]
+	Added tests for the [time] command, which was previously only
+	indirectly tested!
+
+2002-07-18  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclInt.h:
+	* generic/tcl.h:
+	* */*Load*.c: added comments on changes of 07/17 and replaced
+	clientData with Tcl_LoadHandle in all locations.
+
+	* generic/tclFCmd.c:
+	* tests/fileSystem.test: fixed a 'knownBug' with 'file attributes ""'
+	* tests/winFCmd.test:
+	* tests/winPipe.test:
+	* tests/fCmd.test:
+	* tessts/winFile.test: added 'pcOnly' constraint to some tests to make
+	for more useful 'tests skipped' log from running all tests on
+	non-Windows platforms.
+
+2002-07-17  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclBasic.c (CallCommandTraces): delete traces now receive
+	the FQ old name of the command. [Bug 582532] (Don Porter)
+
+2002-07-18  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* tests/ioUtil.test: added constraints to 1.4,2.4 so they don't run
+	outside of tcltest. [Bugs 583276, 583277]
+
+2002-07-17  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclVar.c (DupParsedVarName): nasty bug fixed, reported by
+	Vince Darley.
+
+2002-07-17  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclVar.c (TclPtrIncrVar): missing CONST in declarations,
+	inconsistent with tclInt.h. Thanks to Vince Darley for reporting, boo
+	to gcc for not complaining.
+
+2002-07-17  Vince Darley  <vincentdarley@users.sourceforge.net>

+	* unix/tclLoadOSF.c:
+	* unix/tclLoadShl.c:
+	* mac/tclMacLoad.c:
+	* win/tclWinLoad.c: modified to move more functionality to the generic
+	code and avoid duplication. Partial replacement of internal uses of
+	clientData with opaque Tcl_LoadHandle. A little further work still
+	needed, but significant changes are done.
+
+2002-07-17  D. Richard Hipp    <drh@hwaci.com>
+
+	* library/msgcat/msgcat.tcl: fix a comment that was causing problems
+	for programs (ex: mktclapp) that embed the initialization scripts in
+	strings.
+
+2002-07-17  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclInt.decls:
+	* generic/tclIntDecls.h:
+	* generic/tclStubInit.c:
+	* generic/tclVar.c: removing the now redundant functions to access
+	indexed variables: Tcl(Get|Set|Incr)IndexedScalar() and
+	Tcl(Get|Set|Incr)ElementOfIndexedArray().
+
+2002-07-17  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclExecute.c (TclExecuteByteCode): Minor fixes to make this
+	file compile with SunPro CC...
+
+2002-07-17  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c: modified to do variable lookup explicitly, and
+	then either inlining the variable access or else calling the new
+	TclPtr(Set|Get|Incr)Var functions in tclVar.c
+	* generic/tclInt.h: declare some functions previously local to
+	tclVar.c for usage by TEBC.
+	* generic/tclVar.c: removed local declarations; moved all special
+	accessor functions for indexed variables to the end of the file -
+	they are unused and ready for removal, but left there for the time
+	being as they are in the internal stubs table.
+
+	** WARNING FOR BYTECODE MAINTAINERS **
+	TCL_COMPILE_DEBUG is currently not functional; will be fixed ASAP.
+
+2002-07-16  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/Makefile.in:
+	* win/Makefile.in: Add a more descriptive warning in the event `make
+	genstubs` needs to be rerun.
+
+2002-07-16  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/Makefile.in: Use dltest.marker file to keep track of when the
+	dltest package is up to date. This fixes [Bug 575768] since tcltest is
+	no longer linked every time.
+	* unix/dltest/Makefile.in: Create ../dltest.marker after a successful
+	`make all` run in dltest.
+
+2002-07-16  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/configure: Regen.

+2002-07-15  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclVar.c: inaccurate comment fixed
+
+2002-07-15  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclBasic.c (Tcl_AddObjErrorInfo):
+	* generic/tclExecute.c (TclUpdateReturnInfo):
+	* generic/tclInt.h:
+	* generic/tclProc.c:
+	Added two Tcl_Obj to the ExecEnv structure to hold the fully qualified
+	names "::errorInfo" and "::errorCode" to cache the addresses of the
+	corresponding variables. The two most frequent setters of these
+	variables now profit from the new variable name caching.
+
+2002-07-15  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclVar.c: refactorisation to reuse already looked-up Var
+	pointers; definition of three new Tcl_Obj types to cache variable name
+	parsing and lookup for later reuse; modification of internal functions
+	to profit from the caching.
+
+	* generic/tclInt.decls:
+	* generic/tclInt.h:
+	* generic/tclIntDecls.h:
+	* generic/tclNamesp.c: adding CONST qualifiers to variable names
+	passed to Tcl_FindNamespaceVar and to variable resolvers; adding CONST
+	qualifier to the 'msg' argument to TclLookupVar. Needed to avoid code
+	duplication in the new tclVar.c code.
+
+	* tests/set-old.test:
+	* tests/var.test: slight modification of error messages due to the
+	modifications in the tclVar.c code.
+
+2002-07-15  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/unixInit.test:	Improved constraints to protect /tmp. [Bug
+	581403]
+
+2002-07-15  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* tests/winFCmd.test: renamed 'win2000' and 'notWin2000' to more
+	appropriate constraint names.
+	* win/tclWinFile.c: updated comments to reflect 07-11 changes.
+	* win/tclWinFCmd.c: made ConvertFileNameFormat static again, since no
+	longer used in tclWinFile.c
+	* mac/tclMacFile.c: completed TclpObjLink implementation which was
+	previously lacking.
+	* generic/tclIOUtil.c: comment cleanup and code speedup.
+
+2002-07-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclInt.h:	Removed declarations that duplicated entries
+	in the (internal) stub table.
+
+	* library/tcltest/tcltest.tcl:  Corrected errors in handling of
+	configuration options -constraints and -limitconstraints.
+
+	* README:		Bumped HEAD to version 8.4b2 so we can
+	* generic/tcl.h:	distinguish it from the 8.4b1 release.

+
+2002-07-11  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* doc/file.n:
+	* win/tclWinFile.c: on Win 95/98/ME the long form of the path is used
+	as a normalized form. This is required because short forms are not a
+	robust representation. The file normalization function has been sped
+	up, but more performance gains might be possible, if speed is still an
+	issue on these platforms.
+
+2002-07-11  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl: Corrected reaction to existing but
+	false ::tcl_interactive.
+
+	* doc/Hash.3: Overlooked CONST documentation update.
+
+2002-07-11  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclCkalloc.c: ckalloc() and friends take the block size as
+	an unsigned, so we should use %ud when reporting it in fprintf() and
+	panic().
+
+2002-07-11  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompile.c: now setting local vars undefined at compile
+	time, instead of waiting until the proc is initialized.
+	* generic/tclProc.c: use macro TclSetVarUndefined instead of directly
+	setting the flag.
+
+2002-07-11  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/cmdAH.test: [file attr -perm] is Unix-only, so add [catch]
+	when not inside a suitably-protected test.
+
+2002-07-10  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/unixFCmd.test, tests/fileName.test:
+	* tests/fCmd.test: Removed [exec] of Unix utilities that have
+	equivalents in standard Tcl. [Bug 579268] Also simplified some of
+	unixFCmd.test while I was at it.
+
+2002-07-10  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/tcltest.test:  Greatly reduced the number of [exec]s, using
+	slave interps instead.
+	* library/tcltest/tcltest.tcl:  Fixed bug uncovered in the conversion
+	where a message was written to stdout instead of [outputChannel].
+
+	* tests/basic.test:	Cleaned up, constrained, and reduced the
+	* tests/compile.test:	amount of [exec] usage in the test suite.

+
+	* tests/cmdAH.test: Removed [exec] of Unix utilities. [Bug 579211]
+
+	* tests/expr.test: Added tests to make sure that this works.
+	* generic/tclExecute.c (ExprCallMathFunc): Functions should also be
+	able to return wide-ints. [Bug 579284]
+
+2002-07-08  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* tests/socket.test: Fixed [Bug 578164]. The original reason for the
+	was a DNS outage while running the testsuite. Changed [info hostname]
+	to 127.0.0.1 to bypass DNS, knowing that we operate on the local host.
+
+2002-07-08  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/tcltest.n:		Fixed incompatibility in [viewFile].
+	* library/tcltest/tcltest.tcl:	Corrected docs. Bumped to 2.2.1.
+	* library/tcltest/pkgIndex.tcl: [Bug 578163]
+
+2002-07-08  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* tests/cmdAH.test:
+	* tests/fCmd.test:
+	* tests/fileName.test: tests which rely on 'file link' need a
+	constraint so they don't run on older Windows OS. [Bug 578158]
+	* generic/tclIOUtil.c:
+	* generic/tcl.h:
+	* generic/tclInt.h:
+	* generic/tclTest.c:
+	* mac/tclMacChan.c:
+	* unix/tclUnixChan.c:
+	* win/tclWinChan.c:
+	* doc/FileSystem.3: cleaned up internal handling of
+	Tcl_FSOpenFileChannel to remove duplicate code, and make writing
+	external vfs's clearer and easier. No functionality change. Also
+	clarify that objects with refCount zero should not be passed in to the
+	Tcl_FS API, and prevent segfaults from occuring on such user errors.
+	[Bug 578617]
+
+2002-07-06  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/pkgMkIndex.test:  Constrained tests of [load] package indexing
+	to those platforms where the testing shared libraries have been built.
+	[Bug 578166]
+
+2002-07-05  Don Porter  <dgp@users.sourceforge.net>
+
+	* changes: added recent changes
+
+2002-07-05  Reinhard Max  <max@suse.de>
+
+	* generic/tclClock.c (FormatClock): Convert the format string to UTF8
+	before calling TclpStrftime, so that non-ASCII characters don't get
+	mangled when the result string is being converted back.
+	* tests/clock.test: Added a test for that.
+
+2002-07-05  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* unix/Makefile.in (ro-test,ddd,GDB,DDD): Created new targets to
+	allow running the test suite with a read-only current directory,
+	running under ddd instead of gdb, and factored out some executable
+	names for broken sites (like mine) where gdb and ddd are installed
+	with non-standard names...
+
+	* tests/httpold.test: Altered test names to httpold-* to avoid clashes
+	with http.test, and stopped tests from failing when the current
+	directory is not writable...
+
+	* tests/event.test:		Stop these tests from failing when the

+	* tests/winPipe.test:
+	* tests/pid.test: Fixed [Bug 575848]. See below for a description the

+
+	* tests/iogt.test: Fixed [Bug 575860].
+	* tests/io.test:   Fixed [Bug 575862].
+	* tests/exec.test:

+
+	* tests/pkg1/direct1.tcl: removed
+	* tests/pkg1/pkgIndex.tcl: removed
+	* tests/pkgMkIndex.test:  Imported auxilliary files from tests/pkg1

+	* tests/pkg/std.tcl: removed
+	* tests/pkgMkIndex.test: Fixed [Bug 575857] where this test file
+	expected to be able to write to [file join [testsDirectory] pkg]. Part
+	of the fix was to import several auxilliary files into the test file
+	itself.
+
+	* tests/main.test:	Cheap fix for [Bugs 575851, 575858]. Avoid
+	* tests/tcltest.test:	non-writable . by [cd [temporaryDirectory]].
+
+	* library/auto.tcl: Fix [tcl_findLibrary] to be sure it sets $varName
+	only if a successful library script is found. [Bug 577033]
+
+2002-07-03  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompCmds.c (TclCompileCatchCmd): return
+	TCL_OUT_LINE_COMPILE instead of TCL_ERROR: let the failure happen at
+	runtime so that it can be caught [Bug 577015].
+
+2002-07-02  Joe English  <jenglish@users.sourceforge.net>
+
+	* doc/tcltest.n: Markup fixes, spellcheck.

+	constraint is updated whenever the [interpreter] changes.
+
+	* doc/tcltest.n:		Reverted [makeFile] and [viewFile] to

+	* tests/http.test:
+	* tests/io.test:
+
+	* library/tcltest/tcltest.tcl: Simplified logic of [GetMatchingFiles]

+2002-07-01  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Made Solaris use gcc for linking
+	when building with gcc to resolve problems with undefined symbols
+	being present when tcl library used with non-gcc linker at later
+	stage. Symbols were compiler-generated, so it is the compiler's
+	business to define them. [Bug 541181]
+
+2002-07-01  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/tcltest.n: more work in progress updating tcltest docs.
+
+	* library/tcltest/tcltest.tcl: Change [configure -match] to stop
+	treating an empty list as a list of the single pattern "*". Changed
+	the default value to [list *] so default operation remains the same.
+
+	* tests/pkg/samename.tcl: restored. needed by pkgMkIndex.test.
+
+	* library/tcltest/tcltest.tcl: restored writeability testing of
+	-tmpdir, augmented by a special exception for the deafault value.
+
+2002-07-01  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/concat.n: Documented the *real* behaviour of [concat]!
+
+2002-06-30  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/tcltest.n: more work in progress updating tcltest docs.
+
+	* tests/README:		Updated the instructions on running and
+	* tests/cmdMZ.test:	adding to the test suite. Also updated
+	* tests/encoding.test:	several tests, mostly to correctly create
+	* tests/fCmd.test:	and destroy any temporary files in the
+	* tests/info.test:	[temporaryDirectory] of tcltest.
+	* tests/interp.test:
+
+	* library/tcltest/tcltest.tcl:	Stopped checking for writeability of
+	-tmpdir value because no default directory can be guaranteed to be
+	writeable.
+
+	* tests/autoMkindex.tcl: removed.
+	* tests/pkg/samename.tcl: removed.
+	* tests/pkg/magicchar.tcl: removed.
+	* tests/pkg/magicchar2.tcl: removed.
+	* tests/autoMkindex.test: Updated auto_mkIndex tests to use [makeFile]
+	and [removeFile] so tests are done in [temporaryDirecotry] where write
+	access is guaranteed.
+
+	* library/tcltest/tcltest.tcl:	Fixed [makeFile] and [viewFile] to
+	* tests/cmdAH.test:		accurately reflect a file's contents.
+	* tests/event.test:		Updated tests that depended on buggy
+	* tests/http.test:		behavior. Also added warning messages
+	* tests/io.test:		to "-debug 1" operations to debug test
+	* tests/iogt.test:		calls to (make|remove)(File|Directory)
+
+	* unix/mkLinks: `make mklinks` on 6-27 commits.
+
+2002-06-28  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompile.h: modified the macro TclEmitPush to not call its
+	first argument repeatedly or pass it to other macros, [Bug 575194]
+	reported by Peter Spjuth.
+
+2002-06-28  Don Porter  <dgp@users.sourceforge.net>
+
+	* docs/tcltest.n:	Doc revisions in progress.

+	not reliable, and disagreed with docs! Thanks to Hemang Lavana. [Bug
+	575150]
+
+2002-06-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* unix/tclUnixThrd.c:	Renamed the Tcl_Platform* #defines to TclOS*
+	* unix/tclUnixPipe.c:	because they are only used internally. Also
+	* unix/tclUnixFile.c:	stopped double-#def of TclOSlstat [Bug 566099,
+	* unix/tclUnixFCmd.c:	post-rename]
+	* unix/tclUnixChan.c:
+	* unix/tclUnixPort.h:
+
+	* doc/string.n: Improved documentation for [string last] along lines
+	described in [Bug 574799] so it indicates that the supplied index
+	marks the end of the search space.
+
+2002-06-27  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/dde.n:		Work in progress updating the documentation

+	* doc/msgcat.n:		the Tcl source distribution, notably tcltest.
+	* doc/registry.n:
+	* doc/tcltest.n:
+
+	* library/tcltest/tcltest.tcl:  Made sure that the TCLTEST_OPTIONS
+	environment variablle configures tcltest at package load time.
+
+2002-06-26  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* tests/fileSystem.test:
+	* generic/tclIOUtil.c: fix to handling of empty paths "" which are not
+	claimed by any filesystem [Bug 573758]. Ensure good error messages
+	are given in all cases.
+	* tests/cmdAH.test:
+	* unix/tclUnixFCmd.c: fix to bug reported as part of [Patch 566669].
+	Thanks to Taguchi, Takeshi for the report.
+
+2002-06-26  Reinhard Max  <max@suse.de>
+

+
+2002-06-24  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl:	Corrected suppression of -verbose skip
+	* tests/tcltest.test:		and start by [test -output]. Also
+	corrected test suite errors exposed by corrected code. [Bug 564656]
+
+2002-06-25  Reinhard Max  <max@suse.de>
+
+	* unix/tcl.m4:       New macro SC_CONFIG_MANPAGES.
+	* unix/configure.in: Added support for symlinks and compression when
+	* unix/Makefile.in:  installing the manpages. [Patch 518052]
+	* unix/mkLinks.tcl:  Default is still hardlinks and no compression.
+
+	* unix/mkLinks:      generated
+	* unix/configure:
+
+	* unix/README:       Added documentation for the new features.
+
+	* unix/tcl.m4 (SC_PATH_TCLCONFIG): Replaced ${exec_prefix}/lib by
+	${libdir}.
+
+2002-06-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclUtil.c (TclGetIntForIndex): Fix of critical [Bug 533364]
+	generated when the index is bad and the result is a shared object. The
+	T_ASTO(T_GOR, ...) idiom likely exists elsewhere though. Also removed
+	some cruft that just complicated things to no advantage.
+	(SetEndOffsetFromAny): Same fix, though this wasn't on the path
+	excited by the bug.
+
+2002-06-24  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl:	Implementation of TIP 101. Adds abd
+	* tests/parseOld.test:		exports a [configure] command from
+	* tests/tcltest.test:		tcltest.
+
+2002-06-22  Don Porter  <dgp@users.sourceforge.net>
+
+	* changes: updated changes file for 8.4b1 release.
+
+	* library/tcltest/tcltest.tcl:	Corrections to tcltest and the Tcl
+	* tests/basic.test:		test suite so that a test with options
+	* tests/cmdInfo.test:		-constraints knownBug
+	* tests/compile.test:		-limitConstraints 1 only tests the
+	* tests/encoding.test:		knownBug tests. Mostly involves
+	* tests/env.test:		replacing direct access to the
+	* tests/event.test:		testConstraints array with calls to
+	* tests/exec.test:		the testConstraint command (which
+	* tests/execute.test:		requires tcltest version 2)
+	* tests/fCmd.test:

+	* win/README.binary, README, win/configure.in, unix/configure.in:
+	* generic/tcl.h (TCL_RELEASE_*, TCL_PATCH_LEVEL): Bump to beta1.
+
+2002-06-21  Joe English  <jenglish@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:
+	* generic/tclParseExpr.c: LogSyntaxError() should reset the
+	interpreter result [Bug 550142 "Tcl_ExprObj -> abort"]
+
+2002-06-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* unix/Makefile.in:	Updated all package install directories
+	* win/Makefile.in:	to match current Major.minor versions
+	* win/makefile.bc:	of the packages. Added tcltest package
+	* win/makefile.vc:	to installation on Windows.
+
+	* library/init.tcl:  Corrected comments and namespace style issues.
+	Thanks to Bruce Stephens. [Bug 572025]
+
+2002-06-21  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* tests/cmdAH.test:          Added TIP#99 implementation of 'file
+	* tests/fCmd.test:           link'. Supports creation of symbolic and
+	* tests/fileName.test:       hard links in the native filesystems and
+	* tests/fileSystem.test:     in vfs's, when the individual filesystem
+	* generic/tclTest.c:         supports the concept.

+	* doc/FileSystem.3:
+	* doc/file.n:
+	* mac/tclMacFile.c:
+	* unix/tclUnixFile.c:
+	* win/tclWinFile.c: Also enhanced speed of 'file normalize' on
+	Windows.
+
+2002-06-20  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclBasic.c (TclEvalObjvInternal): fix for [Bug 571385] in
+	the implementation of TIP#62 (command tracing). Vince Darley, Hemang
+	Lavana & Don Porter: thanks.
+
+2002-06-20  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c (TclCompEvalObj): clarified and simplified the
+	logic for compilation/recompilation.
+
+2002-06-19  Joe English  <jenglish@users.sourceforge.net>
+
+	* doc/file.n: Fixed indentation. No substantive changes.
+
+2002-06-19  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd): get the resultPtr again as
+	the Tcl_ObjSetVar2 may cause the result to change. [Patch 558324]
+	(watson)
+
+2002-06-19  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c (TEBC): removing unused "for(;;)" loop;
+	improved comments; re-indentation.
+
+2002-06-18  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c (TEBC):
+	- elimination of duplicated code in the non-immediate INST_INCR
+	  instructions.
+	- elimination of 103 (!) TclDecrRefCount macros. The different
+	  instructions now jump back to a common "DecrRefCount zone" at the
+	  top of the loop. The macro "ADJUST_PC" was replaced by two macros
+	  "NEXT_INST_F" and "NEXT_INST_V" that take three params
+	  (pcAdjustment, # of stack objects to discard, resultObjPtr handling
+	  flag). The only instructions that retain a TclDecrRefCount are
+	  INST_POP (for speed), the common code for the non-immediate
+	  INST_INCR, INST_FOREACH_STEP and the two INST_LSET.
+
+	The object size of tclExecute.o was reduced by approx 20% since the
+	start of the consolidation drive, while making room for some peep-hole
+	optimisation at runtime.
+
+2002-06-18  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c (TEBC, INST_DONE): small bug in the panic code
+	for tcl-stack corruption.
+
+2002-06-17  David Gravereaux <davygrvy@pobox.com>
+
+	Trims to support the removal of RESOURCE_INCLUDED from rc scripts from
+	[FRQ 565088].
+
+	* generic/tcl.h: moved the #ifndef RC_INVOKED start block up in the
+	file. rc scripts don't need to know thread mutexes.
+
+	* win/tcl.rc:
+	* win/tclsh.rc: removed the #define RESOURCE_INCLUDED to let the
+	built-in -DRC_INVOKED to the work.
+
+2002-06-17  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* doc/CrtTrace.3:        Added TIP#62 implementation of command
+	* doc/trace.n:           execution tracing [FRQ 462580] (lavana).
+	* generic/tcl.h:         This includes enter/leave tracing as well
+	* generic/tclBasic.c:    as inter-procedure stepping.
+	* generic/tclCmdMZ.c:
+	* generic/tclCompile.c:
+	* generic/tclExecute.c:

+	* tests/trace.test:
+
+2002-06-17  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* win/tclWinPipe.c (BuildCommandLine): Fixed [Bug 554068] ([exec] on
+	windows did not treat { in filenames well.). Bug reported by Vince
+	Darley <vincentdarley@users.sourceforge.net>, patch provided by Vince
+	too.
+
+2002-06-17  Joe English  <jenglish@users.sourceforge.net>
+
+	* generic/tcl.h: #ifdef logic for K&R C backwards compatibility
+	changed to assume modern C by default. See [FRQ 565088] for full
+	details.
+
+2002-06-17  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/msgcat.n: Corrected en_UK references to en_GB. UK is not a
+	country designation recognized in ISO 3166.
+
+	* library/msgcat/msgcat.tcl:  More Windows Registry locale codes from
+	Bruno Haible.
+
+	* doc/msgcat.n:
+	* library/msgcat/msgcat.tcl:
+	* library/msgcat/pkgIndex.tcl:
+	* tests/msgcat.test:  Revised locale initialization to interpret
+	environment variable locale values according to XPG4, and to recognize
+	the LC_ALL and LC_MESSAGES values over that of LANG. Also added many
+	Windows Registry locale values to those recognized by msgcat. Revised
+	tests and docs. Bumped to version 1.3. Thanks to Bruno Haible for the
+	report and assistance crafting the solution. [Bug 525522, 525525]
+
+2002-06-16  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompile.c (TclCompileTokens): a better algorithm for the
+	previous bug fix.
+
+2002-06-16  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompile.c (TclCompileTokens):
+	* tests/compile.test: [Bug 569438] in the processing of dollar
+	variables; report by Georgios Petasis.
+
+2002-06-16  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c: bug in the consolidation of the INCR_..._STK
+	instructions; the bug could not be exercised as the (faulty)
+	instruction INST_INCR_ARRAY_STK was never compiled-in (related to [Bug
+	569438]).
+
+2002-06-14  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c (TclExecuteByteCode): runtime peep-hole
+	optimisation of variables (INST_STORE, INST_INCR) and commands
+	(INST_INVOKE); faster check for the existence of a catch.
+	(TclExecuteByteCode): runtime peep-hole optimisation of comparisons.
+	(TclExecuteByteCode): runtime peep-hole optimisation of INST_FOREACH -
+	relies on peculiarities of the code produced by the bytecode compiler.
+
+2002-06-14  David Gravereaux <davygrvy@pobox.com>
+
+	* win/rules.vc: The test for compiler optimizations was in error.
+	Thanks goes to Roy Terry <royterry@earthlink.net> for his assistance
+	with this.
+
+2002-06-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/trace.n, tests/trace.test:
+	* generic/tclCmdMZ.c (Tcl_TraceObjCmd,TclTraceCommandObjCmd)
+	(TclTraceVariableObjCmd): Changed references to "trace list" to
+	"trace info" as mandated by TIP#102.
+
+2002-06-13  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c (TclExecuteByteCode): consolidated code for the
+	conditional branch instructions.
+
+2002-06-13  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c (TclExecuteByteCode): fixed the previous patch;
+	wouldn't compile with TCL_COMPILE_DEBUG set.
+
+2002-06-13  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c (TclExecuteByteCode): consolidated the handling
+	of exception returns to INST_INVOKE and INST_EVAL, as well as most of
+	the code for INST_CONTINUE and INST_BREAK, in the new jump target
+	"processExceptionReturn".
+
+2002-06-13  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c (TclExecuteByteCode): consolidated variable
+	handling opcodes, replaced redundant code with some 'goto'. All
+	store/append/lappend opcodes on the same data type now share the main
+	code; same with incr opcodes.
+	* generic/tclVar.c: added the bit TCL_TRACE_READS to the possible
+	flags to Tcl_SetVar2Ex - it causes read traces to be fired prior to
+	setting the variable. This is used in the core for [lappend].
+
+	***NOTE*** the usage of TCL_TRACE_READS in Tcl_(Obj)?GetVar.* is not
+	documented; there, it causes the call to create the variable if it
+	does not exist. The new usage in Tcl_(Obj)?SetVar.* remains
+	undocumented too ...
+
+2002-06-13  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* tests/fCmd.test:
+	* tests/winFile.test:
+	* tests/fileSystem.test:
+	* generic/tclTest.c:
+	* generic/tclCmdAH.c:
+	* generic/tclIOUtil.c:
+	* doc/FileSystem.3:
+	* mac/tclMacFile.c:
+	* unix/tclUnixFile.c:
+	* win/tclWinFile.c: fixed up further so both compiles and actually
+	works with VC++ 5 or 6.
+	* win/tclWinInt.h:
+	* win/tclWin32Dll.c: cleaned up code and vfs tests and added tests for
+	the internal changes of 2002-06-12, to see whether WinTcl on NTFS can
+	coexist peacefully with links in the filesystem. Added new test
+	command 'testfilelink' to enable the newer code to be tested.
+	* tests/fCmd.test: (made certain tests of 'testfilelink' not run on
+	unix).
+
+2002-06-12  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* tclBasic.c (Tcl_DeleteTrace): fixed [Bug 568123] (thanks to Hemang
+	Lavana)
+
+2002-06-12  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/tclWinFile.c: corrected the symbolic link handling code to allow
+	it to compile. Added real definition of REPARSE_DATA_BUFFER (found in
+	winnt.h). Most of the added definitions appear to have correct,
+	cross-Win-version equivalents in winnt.h and should be removed, but
+	just making things "work" for now.
+
+2002-06-12  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c:
+	* generic/tcl.decls:
+	* generic/tclDecls.h: made code for Tcl_FSNewNativePath agree with man
+	pages.
+
+	* doc/FileSystem.3: clarified the circumstances under which certain
+	functions are called in the presence of symlinks.
+
+	* win/tclWinFile.c:
+	* win/tclWinPort.h:
+	* win/tclWinInt.h:
+	* win/tclWinFCmd.c:  Fix for Windows to allow 'file lstat', 'file
+	type', 'glob -type l', 'file copy', 'file delete', 'file normalize',
+	and all VFS code to work correctly in the presence of symlinks
+	(previously Tcl's behaviour was not very well defined). This also
+	fixes possible serious problems in all versions of WinTcl where 'file
+	delete' on a NTFS symlink could delete the original, not the symlink.
+	Note: symlinks cannot yet be created in pure Tcl.
+
+2002-06-11  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclBasic.c:
+	* generic/tclCompCmds.c:
+	* generic/tclInt.h: reverted the new compilation functions; replaced
+	by a more general approach described below.
+
+	* generic/tclCompCmds.c:
+	* generic/tclCompile.c: made *all* compiled variable access attempts
+	create an indexed variable - even get or incr without previous set.
+	This allows indexed access to local variables that are created and set
+	at runtime, for example by [global], [upvar], [variable], [regexp],
+	[regsub].
+
+2002-06-11  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* doc/global.n:
+	* doc/info.n:
+	* test/info.test:
+	* generic/tclCmdIL.c: fix for [Bug 567386], [info locals] was
+	reporting some linked variables.
+
+	* generic/tclBasic.c:
+	* generic/tclCompCmds.c:
+	* generic/tclInt.h: added compile functions for [global], [variable]
+	and [upvar]. They just declare the new local variables, the commands
+	themselves are not compiled-in. This gives a notably faster read
+	access to these linked variables.
+
+2002-06-11  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclExecute.c: optimised algorithm for exception range
+	lookup; part of [Patch 453709].
+
+2002-06-10  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* unix/tclUnixFCmd.c: fixed [Bug 566669]
+	* generic/tclIOUtil.c: improved and sped up handling of native paths
+	(duplication and conversion to normalized paths), particularly on
+	Windows.
+	* modified part of above commit, due to problems on Linux. Will
+	re-examine bug report and evaluate more closely.
+
+2002-06-07  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/tcltest.test:  More corrections to test suite so that tests of
+	failing [test]s don't show up themselves as failing tests.
+
+2002-06-07  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclExecute.c: Tidied up headers in relation to float.h to
+	cut the cruft and ensure DBL_MAX is defined since doubles seem to be
+	the same size everywhere; if the assumption isn't true, the variant
+	platforms had better have run configure...
+
+	* unix/tclUnixPort.h (EOVERFLOW): Added code to define it if it
+	wasn't previously defined. Also some other general tidying and adding
+	of comments. [Bugs 563122, 564595]
+	* compat/tclErrno.h: Added definition for EOVERFLOW copied from
+	Solaris headers; I've been unable to find any uses of EFTYPE, which
+	was the error code previously occupying the slot, in Tcl, or any
+	definition of it in the Solaris headers.
+
+2002-06-06  Mo DeJong  <mdejong@users.sourceforge.net>

+
+2002-06-06  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/tcltest.test:  Corrections to test suite so that tests of
+	failing [test]s don't show up themselves as failing tests.
+
+	* tests/io.test: Fixed up namespace variable resolution issues
+	revealed by running test suite with "-singleproc 1".
+
+	* doc/tcltest.n:
+	* library/tcltest/tcltest.tcl:
+	* tests/tcltest.test: Several updates to tcltest.
+	  1) changed to lazy initialization of test constraints
+	  2) deprecated [initConstraintsHook]

+
+2002-06-06  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tclUnixThrd.c (TclpReaddir, TclpLocaltime, TclpGmtime): added
+	mutex wrapped calls to readdir, localtime & gmtime in case their
+	thread-safe *_r counterparts are not available.
+	* unix/tcl.m4: added configure check for readdir_r
+	* unix/tcl.m4 (Darwin): set TCL_DEFAULT_ENCODING to utf-8 on MacOSX
+	(where posix file apis expect utf-8, not iso8859-1).
+	* unix/configure: regen
+	* unix/Makefile.in: set DYLD_LIBRARY_PATH in parallel to
+	LD_LIBRARY_PATH for MacOSX dynamic linker.
+	* generic/tclEnv.c (TclSetEnv): fix env var setting on MacOSX (adapted
+	from [Patch 524352] by jkbonfield).
+
+2002-06-05  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/Tcl_Main.3: Documented $tcl_rcFileName and added more
+	clarifications about the intended use of Tcl_Main(). [Bug 505651]
+
+2002-06-05  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclFileName.c (TclGlob): mac specific fix to recent changes
+	in 'glob -tails' handling.
+	* mac/tclMacPort.h:
+	* mac/tclMacChan.c: fixed TIP#91 bustage.
+	* mac/tclMacResource.c (Tcl_MacConvertTextResource): added utf

+
+	* library/tcltest/tcltest.tcl:
+	* tests/init.test:
+	* tests/tcltest.test:	Added more TIP 85 tests from Arjen Markus.
+	Converted tcltest.test to use a private namespace. Fixed bugs in
+	[tcltest::Eval] revealed by calling [tcltest::test] from a non-global
+	namespace, and namespace errors in init.test.
+
+2002-06-04  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/README: Update msys+mingw URL.

+
+	* doc/tcltest.n:
+	* library/tcltest/tcltest.tcl:
+	* library/tcltest/pkgIndex.tcl:
+	* tests/tcltest.test:  Implementation of TIP 85. Allows tcltest users

+2002-06-03  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* doc/Tcl.n: clarify the empty variable name issue ([Bug 549285]

+
+2002-05-31  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/package.tcl:  Fixed leak of slave interp in [pkg_mkIndex].
+	Thanks to Helmut for report. [Bug 550534]

+	* unix/configure.in (NEED_MATHERR):
+	* unix/tclAppInit.c (matherr):
+	* unix/tclMtherr.c (removed file):
+	* win/tclWinMtherr.c (_matherr): Removed internal routine
+	TclMathInProgress and Unix implementation of matherr(). These are now
+	obsolete, dealing with very old versions of the C math library.
+	Windows version is retained in case Borland compilers require it, but
+	it is inactive. Thanks to Joe English. [Bug 474335, Patch 555635]
+
+	* unix/configure: regen
+
+2002-05-30  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:
+	* generic/tclCompile.c:
+	* generic/tclCompile.h: removed exprIsJustVarRef and
+	exprIsComparison from the ExprInfo and CompileEnv structs. These
+	were set, but not used since dec 1999 [Bug 562383].
+
+2002-05-30  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclFileName.c (TclGlob): fix to longstanding 'knownBug' in
+	fileName tests 15.2-15.4, and fix to a new Tcl 8.4 bug in certain uses
+	of 'glob -tails'.
+	* tests/fileName.test: removed 'knownBug' flag from some tests, added
+	some new tests for above bugs.
+
+2002-05-29  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* unix/configure: regen'ed
+	* unix/configure.in: replaced bigendian check with autoconf standard
+	AC_C_BIG_ENDIAN, which defined WORDS_BIGENDIAN on bigendian systems.
+	* generic/tclUtf.c (Tcl_UniCharNcmp):
+	* generic/tclInt.h (TclUniCharNcmp): use WORDS_BIGENDIAN instead of
+	TCL_OPTIMIZE_UNICODE_COMPARE to enable memcmp alternative.
+
+	* generic/tclExecute.c (TclExecuteByteCode INST_STR_CMP):
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): changed the case for choosing
+	the Tcl_UniCharNcmp compare to when both objs are of StringType, as
+	benchmarks show that is the optimal check (both bigendian and
+	littleendian systems).
+
+2002-05-29  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclMain.c: Removed "dummy" reference to Tcl_LinkVar. It is
+	no longer needed since Tcl_Main() now actually calls Tcl_LinkVar().
+	Thanks to Joe English for pointing that out.
+
+2002-05-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclExecute.c (TclExecuteByteCode):
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Use the macro version.
+	* generic/tclInt.h (TclUniCharNcmp): Optimised still further with a
+	macro for use in sensitive places like tclExecute.c
+
+	* generic/tclUtf.c (Tcl_UniCharNcmp): Use new flag to figure out when
+	we can use an optimal comparison scheme, and default to the old scheme
+	in other cases which is at least safe.
+	* unix/configure.in (TCL_OPTIMIZE_UNICODE_COMPARE): New optional flag
+	that indicates when we can use memcmp() to compare Unicode strings
+	(i.e. when the high-byte of a Tcl_UniChar precedes the low-byte.)
+
+2002-05-29  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclInt.decls:
+	* generic/tclIntDecls.h:
+	* generic/tclStubInit.c:
+	* generic/tclUtf.c: added TclpUtfNcmp2 private command that
+	mirrors Tcl_UtfNcmp, but takes n in bytes, not utf-8 chars. This
+	provides a faster alternative for comparing utf strings	internally.
+	(Tcl_UniCharNcmp, Tcl_UniCharNcasecmp): removed the explicit end of
+	string check as it wasn't correct for the function (by doc and logic).
+
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): reworked the string equal
+	comparison code to use TclpUtfNcmp2 as well as short-circuit for
+	equal objects or unequal length strings in the equal case.
+	Removed the use of goto and streamlined the other parts.
+
+	* generic/tclExecute.c (TclExecuteByteCode): added check for object
+	equality in the comparison instructions. Added short-circuit for !=
+	length strings in INST_EQ, INST_NEQ and INST_STR_CMP. Reworked
+	INST_STR_CMP to use TclpUtfNcmp2 where appropriate, and only use
+	Tcl_UniCharNcmp when at least one of the objects is a Unicode obj with
+	no utf bytes.
+
+	* generic/tclCompCmds.c (TclCompileStringCmd): removed error creation
+	in code that no longer throws an error.
+
+	* tests/string.test:
+	* tests/stringComp.test: added more string comparison checks.
+
+	* tests/clock.test: better qualified 9.1 constraint check for %s.
+
+2002-05-28  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclThreadAlloc.c (TclpRealloc, TclpFree): protect
+	against the case when NULL is based.
+
+	* tests/clock.test: added clock-9.1
+	* compat/strftime.c:
+	* generic/tclClock.c:
+	* generic/tclInt.decls:
+	* generic/tclIntDecls.h:
+	* unix/tclUnixTime.c: fix for Windows msvcrt mem leak caused by using
+	an env(TZ) setting trick for in clock format -gmt 1. This also makes
+	%s seem to work correctly with -gmt 1 as well as making it a lot
+	faster by avoid the env(TZ) hack. TclpStrftime now takes useGMT as an
+	arg. [Bug 559376]
+
+2002-05-28  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c: fixes to Tcl_FSLoadFile when called on a file
+	inside a vfs. This should avoid leaving temporary files sitting
+	around on exit. [Bug 545579]
+
+2002-05-27  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* win/tclWinError.c: Added comment on conversion of
+	ERROR_NEGATIVE_SEEK because that is a mapping that really belongs,
+	and not a catch-all case.
+	* win/tclWinPort.h (EOVERFLOW): Should be either EFBIG or EINVAL
+	* generic/tclPosixStr.c (Tcl_ErrnoId, Tcl_ErrnoMsg): EOVERFLOW can
+	potentially be a synonym for EINVAL.
+
+2002-05-24  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	=== Changes due to TIP#91 ===
+
+	* win/tclWinPort.h: Added declaration of EOVERFLOW.
+	* doc/CrtChannel.3: Added documentation of wideSeekProc.
+	* generic/tclIOGT.c (TransformSeekProc, TransformWideSeekProc):
+	Adapted to use the new channel mechanism.
+	* unix/tclUnixChan.c (FileSeekProc, FileWideSeekProc): Renamed
+	FileSeekProc to FileWideSeekProc and created new FileSeekProc which
+	has the old-style interface and which errors out with EOVERFLOW when
+	the returned file position can't fit into the return type (int for
+	historical reasons).
+	* win/tclWinChan.c (FileSeekProc, FileWideSeekProc): Renamed
+	FileSeekProc to FileWideSeekProc and created new FileSeekProc which
+	has the old-style interface and which errors out with EOVERFLOW when
+	the returned file position can't fit into the return type (int for
+	historical reasons).
+	* mac/tclMacChan.c (FileSeek): Reverted to old interface; Macs lack
+	large-file support because I can't see how to add it.
+	* generic/tclIO.c (Tcl_Seek, Tcl_Tell): Given these functions
+	knowledge of the new arrangement of channel types.
+	(Tcl_ChannelVersion): Added recognition of new version code.
+	(HaveVersion): New function to do version checking.
+	(Tcl_ChannelBlockModeProc, Tcl_ChannelFlushProc)
+	(Tcl_ChannelHandlerProc): Made these functions use HaveVersion for
+	ease of future maintainability.
+	(Tcl_ChannelBlockModeProc): Obvious lookup function.
+	* generic/tcl.h (Tcl_ChannelType): New wideSeekProc field, and
+	seekProc type restored to old interpretation.
+	(TCL_CHANNEL_VERSION_3): New channel version.
+
+2002-05-24  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* tests/winPipe.test: Applied patch for [Bug 549617]. Patch and bug
+	report by Kevin Kenny <kennykb@users.sourceforge.net>.
+
+	* win/tclWinSock.c (TcpWatchProc): Fixed [Bug 557878]. We are not
+	allowed to mess with the watch mask if the socket is a server socket.
+	I believe that the original reporter is George Peter Staplin.
+
+2002-05-21  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/configure: Regen.
+	* unix/configure.in: Invoke SC_ENABLE_SHARED before calling
+	SC_CONFIG_CFLAGS so that the SHARED_BUILD variable can be checked
+	inside SC_CONFIG_CFLAGS.
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Pass -non_shared instead of -shared
+	to ld when configured with --disable-shared under OSF. [Bug 540390]
+
+2002-05-20  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclInt.h: added prototype for TclpFilesystemPathType().
+	* mac/tclMacChan.c: use MSL provided creator type if available instead
+	of the default 'MPW '.
+
+2002-05-16  Joe English  <jenglish@users.sf.net>
+
+	* doc/CrtObjCmd.3: Added Tcl_GetCommandFromObj, Tcl_GetCommandFullName
+	[Bugs 547987, 414921]
+
+2002-05-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* unix/tclUnixChan.c (TtyOutputProc): #if/#endif-ed this function out
+	to stop compiler warnings. Also much general tidying of comments in
+	this file and removal of whitespace from blank lines.
+
+2002-05-13  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* unix/tclUnixChan.c (SETBREAK): Solaris thinks ioctl() takes a signed
+	second argument, and Linux thinks ioctl() takes an unsigned second
+	argument. So need a longer definition of this macro to get neither to
+	spew warnings...
+
+2002-05-13  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclEvent.c:
+	* generic/tclIOUtil.c:
+	* generic/tclInt.h: clean up all memory allocated by the filesystem,
+	via introduction of 'TclFinalizeFilesystem'.
+	Move TclFinalizeLoad into TclFinalizeFilesystem so we can be sure it
+	is called at just the right time.
+	Fix bad comment also. [Bug 555078 and 'fs' part of 543549]
+	* win/tclWinChan.c: fix comment referring to wrong function.
+
+2002-05-10  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/load.test:
+	* tests/safe.test:
+	* tests/tcltest.test: Corrected some list-quoting issues and other
+	matters that cause tests to fail when the patch includes special
+	characters. Report from Vince Darley. [Bug 554068]
+
+2002-05-08    David Gravereaux <davygrvy@pobox.com>
+
+	* doc/file.n:
+	* tools/man2tcl.c:
+	* tools/man2help2.tcl:  Thanks to Peter Spjuth
+	<peter.spjuth@space.se>, again. My prior fix for single-quote macro
+	mis-understanding was wrong. Reverted to reimpliment the 'macro2' proc
+	which handles single-quote macros and restored file.n text arrangement
+	to avoid single-quotes on the first line. Sorry for all the confusion.
+
+2002-05-08  David Gravereaux <davygrvy@pobox.com>
+
+	* tools/man2tcl.c:
+	* tools/man2help2.tcl: Proper source of macro error misunderstanding
+	single-quote as the leading macro command found and repaired.
+
+	* doc/file.n: Reverted to prior state before I messed with it.
+
+2002-05-08  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl: Corrected [uplevel] quoting when
+	[source]-ing test script in subdirectories.
+	* tests/fileName.test:
+	* tests/load.test:
+	* tests/main.test:
+	* tests/tcltest.test:
+	* tests/unixInit.test: Fixes to test suite when there's a space in the
+	working path. Thanks to Kevin Kenny.
+
+2002-05-07  David Gravereaux <davygrvy@pobox.com>
+
+	-- Changes from Peter Spjuth <peter.spjuth@space.se>
+	* tools/man2tcl.c: Increased line buffer size and a bail-out if that
+	should ever be over-run.
+	* tools/man2help.tcl: Include Courier New font in rtf header.
+	* tools/man2help2.tcl: Improved handling of CS/CE fields. Use Courier
+	New for code samples and indent better.
+
+	* doc/file.n:
+	* doc/TraceCmd.3:  winhelp conversion tools where understanding
+	a ' as the first character on a line to be an unknown macro.
+	Not knowing how to repair tools/man2tcl.c, I decided to rearrange
+	the text in the docs instead.
+
+2002-05-07  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclFileName.c: fix to similar segfault when using 'glob
+	-types nonsense -dir dirname -join * *'. [Bug 553320]
+
+	* doc/FileSystem.3: further documentation on vfs.
+	* tests/cmdAH.test:
+	* tests/fileSystem.test:
+	* tests/pkgMkindex.test: Fix to testsuite bugs when running out of
+	directory whose name contains '{' or '['.
+
+2002-05-07  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* tests/basic.test: Fix for [Bug 549607]
+	* tests/encoding.test: Fix for [Bug 549610]
+	These are testsuite bugs that caused failures when the filename
+	contained spaces. Report & fix by Kevin Kenny.
+
+2002-05-02  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclFileName.c: fix to freeing a bad object (i.e. segfault)
+	when using 'glob -types nonsense -dir dirname'.
+	* generic/tclWinFile.c: fix to [Bug 551306], also wrapped some long
+	lines.
+	* tests/fileName.test: added several tests for the above bugs.
+	* doc/FileSystem.3: clarified documentation on refCount requirements
+	of the object returned by the path type function.
+	* generic/tclIOUtil.c:
+	* win/tclWinFile.c:
+	* unix/tclUnixFile.c:
+	* mac/tclMacFile.c: moved TclpFilesystemPathType to the platform-
+	specific directories, so we can add missing platform-specific
+	implementations. On Windows, 'file system' now returns useful results
+	like "native NTFS", "native FAT" for that system. Unix and MacOS still
+	only return "native".
+	* doc/file.n: clarified documentation.
+	* tests/winFile.test: test for 'file system' returning correct values.
+	* tests/fileSystem.test: test for 'file system' returning correct
+	values. Clean up after failed previous test run.
+
+2002-04-26  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* unix/configure:
+	* unix/tcl.m4: change HP-11 SHLIB_LD_LIBS from "" to ${LIBS} so that
+	the .sl knows its dependent libs.
+
+2002-04-26  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/obj.test (obj-11.[56]): Test conversion to boolean more
+	thoroughly.
+	* generic/tclObj.c (SetBooleanFromAny): Was not calling an integer
+	parsing function on native 64-bit platforms! [Bug 548686]
+
+2002-04-24  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclInt.h: corrected TclRememberJoinableThread decl to use
+	VOID instead of void.
+	* generic/tclThreadJoin.c: noted that this code isn't needed on Unix.
+
+2002-04-23  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* doc/exec.n:
+	* doc/tclvars.n: doc updates [Patch 509426] (gravereaux)
+
+2002-04-24  Daniel Steffen  <das@users.sourceforge.net>
+
+	* mac/tclMacResource.r: added check of TCLTK_NO_LIBRARY_TEXT_RESOURCES
+	#define to allow disabling the inclusion of the tcl library code in
+	the resource fork of Tcl executables and shared libraries.
+
+2002-04-23  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/TraceCmd.3: New file that documents Tcl_CommandTraceInfo,
+	Tcl_TraceCommand and Tcl_UntraceCommand [Bug 414927]
+
+2002-04-22  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclAlloc.c:
+	* generic/tclInt.h:
+	* generic/tclThreadAlloc.c (new):
+	* unix/Makefile.in:
+	* unix/tclUnixThrd.c:
+	* win/Makefile.in:
+	* win/tclWinInt.h:
+	* win/tclWinThrd.c: added new threaded allocator contributed by AOL
+	that significantly reduces lock contention when multiple threads are
+	in use. Only Windows and Unix implementations are ready, and the
+	Windows one may need work. It is only used by default on Unix for now,
+	and requires that USE_THREAD_ALLOC be defined (--enable-threads on
+	Unix will define this).
+
+	* generic/tclIOUtil.c (Tcl_FSRegister, Tcl_FSUnregister): corrected
+	calling of Tcl_ConditionWait to ensure that there would be a condition
+	to wait upon.
+
+	* generic/tclCmdAH.c (Tcl_FileObjCmd): added cast in FILE_SIZE.
+
+	* win/tclWinFCmd.c (DoDeleteFile): check return of setattr API calls
+	in file deletion for correct Win32 API handling.
+
+	* win/Makefile.in: correct dependencies for shell, gdb, runtest
+	targets.
+
+	* doc/clock.n:
+	* compat/strftime.c (_fmt): change strftime to correctly handle
+	localized %c, %x and %X on Windows. Added some notes about how the
+	other values could be further localized.
+
+2002-04-19  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclMain.c (Tcl_Main):  Free the memory allocated for the
+	startup script path. [Bug 543549]
+
+	* library/msgcat/msgcat.tcl:  [mcmax] wasn't using the caller's
+	namespace when determining the max translated length. Also made
+	revisions for better use of namespace variables and more efficient
+	[uplevel]s.
+
+	* doc/msgcat.n:
+	* library/msgcat/msgcat.tcl:
+	* library/msgcat/pkgIndex.tcl:  Added [mcload] to the export list of
+	msgcat; bumped to 1.2.3. [Bug 544727]
+
+2002-04-20  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclInt.decls:
+	* generic/tclIntPlatDecls.h:
+	* generic/tclStubInit.c:
+	* mac/tclMacFCmd.c:
+	* mac/tclMacFile.c:
+	* mac/tclMacUtil.c: Modified TclpObjNormalizePath to be alias file
+	aware, and replaced various calls to FSpLocationFrom*Path by calls to
+	new alias file aware versions FSpLLocationFrom*Path. The alias file
+	aware routines don't resolve the last component of a path if it is an
+	alias. This allows [file copy/delete] etc. to act correctly on alias
+	files. (c.f. discussion in [Bug 511666])
+
+2002-04-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/lindex.test (lindex-3.7):
+	* generic/tclUtil.c (TclGetIntForIndex): Stopped indexes from hitting
+	wide ints. [Bug 526717]
+
+2002-04-18  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclNamesp.c:
+	* tests/info.test: [Bug 545325] info level didn't report namespace
+	eval, bug report by Richard Suchenwirth.
+
+2002-04-18  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/subst.n:  Clarified documentation on handling unusual return

+
+	* generic/tclCmdMZ.c (Tcl_SubstObj): More clarification for comment on

+2002-04-18  Miguel Sofer  <msofer@users.sourceforge.net>
+

+
+2002-04-06  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* unix/tclUnixFCmd.c (Realpath): added a little extra code to

+
+2002-04-05  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c (Tcl_SubstObj):

+
+2002-04-03  Jeff Hobbs  <jeffh@ActiveState.com>

+
+	* generic/tclCmdMZ.c (Tcl_TraceObjCmd, TraceVarProc)

+	the tools/ directory. This does not address the syntax errors in the
+	man files. Having the contents of tcl.hpj(.in) inside makefile.vc
+	allows for version numbers to be replaced with macros.
+
+	The new nmakehlp.c is built by rules.vc in preprocessing and removes
+	the need to use tricky shell syntax that wasn't compatible on Win9x
+	systems. Clean targets made Win9x complient. This is a first draft
+	repair for [Bug 533862].

+
+2002-03-25  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/main.test: Removed workarounds for Bug 495977.
+
+	* library/tcltest/tcltest.tcl:  Keep the value of $::auto_path
+	unchanged, so that the tcltest package can test code that depends on

+	only, and 'file normalize' which wasn't very clear before. Removed
+	inconsistency betweens docs and the Tcl_Filesystem structure. Also
+	fixed [Bug 523217] and corrected file normalization on Unix so that
+	it expands symbolic links. Added some new tests of the filesystem
+	code (in the new file 'fileSystem.test'), and some extra tests for
+	correct handling of symbolic links. Fix to [Bug 530960] which shows up
+	on Win98. Made comparison with ".com" case insensitive in tclWinPipe.c
+
+	***POTENTIAL INCOMPATIBILITY***: But only between alpha releases
+	(users of the new Tcl_Filesystem lookup table in Tcl 8.4a4 need to
+	handle the new way in which Tcl may call Tcl_FSMatchInDirectory, and
+	'file normalize' on unix now behaves correctly). Only known impact is
+	with the 'tclvfs' extension.

+
+	* generic/tclMain.c (Tcl_Main,StdinProc):  Corrected some reference
+	count management errors on the interactive command Tcl_Obj found by
+	Purify. Thanks to Jeff Hobbs for the report and assistance.
+
+2002-02-27  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclBasic.c (Tcl_EvalTokensStandard): corrected mem leak in
+	error case.
+
+	* generic/tclTest.c (TestStatProc[123]): correct harmless UMRs.
+
+	* generic/tclLink.c (Tcl_LinkVar): correct mem leak in error case.
+
+2002-02-27  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* tests/socket.test (2.7): Accepted and applied patch for [Bug 523470]
+	provided by Don Porter <dgp@users.sourceforge.net> to avoid timing
+	problems in that test.
+
+	* unix/tclUnixChan.c (TclpOpenFileChannel): Added code to regonize
+	"/dev/tty" (by name) and to not handle it as tty / serial line. This
+	is the controlling terminal and is special. Setting it into raw mode
+	as is done for other tty's is a bad idea. This is a hackish fix for
+	expect [Bug 520624]. The fix has limitation: Tcl_MakeFileChannel
+	handles tty's specially too, but is unable to recognize /dev/tty as it
+	only gets a file descriptor, and no name for it.
+
+2002-02-26  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclCmdAH.c (StoreStatData): corrected mem leak.
+
+	* generic/tclCmdMZ.c (Tcl_RegsubObjCmd): prevent obj leak in
+	remedial regsub case.
+
+	* generic/tclFileName.c (Tcl_TranslateFileName): decr refcount for
+	error case to prevent mem leak.
+
+	* generic/tclVar.c (Tcl_ArrayObjCmd): removed extra obj allocation.
+
+	* unix/tclUnixSock.c (Tcl_GetHostName): added an extra
+	gethostbyname check to guard against failure with truncated
+	names returned by uname.
+
+	* unix/configure:
+	* unix/tcl.m4 (SC_SERIAL_PORT): added sys/modem.h check and defined
+	_XOPEN_SOURCE_EXTENDED for HP-11 to get updated header decls.
+
+	* unix/tclUnixChan.c: added Unix implementation of TIP #35, serial
+	port support. [Patch 438509] (schroedter)
+
+2002-02-26  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCmpCmds.c: (bugfix to the bugfix, hopefully the last)
+	Bugfix to the new [for] compiling code: was setting a exceptArray
+	parameter using another param which wasn't yet initialised, thus
+	filling it with noise.
+
+2002-02-25  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* mac/tclMacSock.c (TcpGetOptionProc): Changed to recognize the option
+	"-error". Essentially ignores the option, always returning an empty
+	string.
+
+2002-02-25  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* doc/Alloc.3:
+	* doc/LinkVar.3:
+	* doc/ObjectType.3:
+	* doc/PkgRequire.3:
+	* doc/Preserve.3:
+	* doc/TCL_MEM_DEBUG.3: Updated documentation to describe the ckalloc,
+	ckfree, ckrealloc, attemptckalloc, and attemptckrealloc macros, and
+	to accurately describe when and how they are used. [Bug 497459] (dgp)
+
+	* generic/tclHash.c (AllocArrayEntry, AllocStringEntry):
+	Before invoking ckalloc when creating a Tcl_HashEntry,
+	check that the amount of memory being allocated is
+	at least as large as sizeof(Tcl_HashEntry). The previous
+	code was allocating memory regions that were one
+	or two bytes short. [Bug 521950] (dejong)
+
+2002-02-25  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclBasic.c (Tcl_EvalEx): avoiding a buffer overrun
+	reported by Joe English, and restoring tcl7.6 behaviour for
+	[subst]: badly terminated nested scripts will raise an error
+	and not be evaluated. [Bug 495207]
+
+2002-02-25  Don Porter  <dgp@users.sourceforge.net>
+
+	* unix/tclUnixPort.h: corrected strtoll prototype mismatch on Tru64.
+	* compat/strtod.c (strtod): simplified #includes
+	* compat/strtol.c (strtol): gather result in a long before returning
+	as a long: necessary on platforms where sizeof(int) != sizeof(long).
+
+2002-02-25  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tclLoadDyld.c: updated to use Mac OS X 10.1 dyld APIs that
+	have more libdl-like semantics. [Bug 514392]
+
+2002-02-25  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompCmds: fixing a bug in patch dated 2002-02-22, in the
+	code for [for] and [while]. Under certain conditions, for long bodies,
+	the exception range parameters were badly computed. Tests forthcoming:
+	I still can't reproduce the conditions in the testsuite (!), although
+	the bug (with assorted segfault or panic!)  can be triggered from the
+	console or with the new parse.bench in tclbench.
+
+2002-02-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* compat/strtoul.c, compat/strtol.c, compat/strtod.c: Added UCHAR,
+	CONST and #includes to clean up GCC output.
+
+2002-02-23  Don Porter  <dgp@users.sourceforge.net>
+
+	* compat/strtoull.c (strtoull):
+	* compat/strtoll.c (strtoll):
+	* compat/strtoul.c (strtoul): Fixed failure to handle leading
+	sign symbols '+' and '-' and '0X' and raise overflow errors.
+	[Bug 440916]  Also corrects prototype and errno problems.
+
+2002-02-23  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* configure: Regen.
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Link with -n32 instead of -32 when
+	building on IRIX64-6.* system. [Bug 521707]
+
+2002-02-22  Don Porter <dgp@users.sourceforge.net>
+
+	* generic/tclInt.h:
+	* generic/tclObj.c: renamed global variable emptyString ->
+	tclEmptyString because it is no longer static.
+	* generic/tclPkg.c: Fix for panic when library is loaded on a
+	platform without backlinking without proper use of stubs. [Bug 476537]
+
+2002-02-22  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tests/regexpComp.test: updated regexp-11.[1-4] to match changes in
+	regexp.test for new regsub syntax
+
+	* unix/configure:
+	* unix/tcl.m4: added --enable-64bit support for AIX-4 (using -q64
+	flag) when using IBM's xlc compiler.
+
+	* tests/safe.test: updated safe-8.5 and safe-8.7
+	* library/safe.tcl (CheckFileName): removed the limit on
+	sourceable file names (was only *.tcl or tclIndex files with no more
+	than one dot and 14 chars). There is enough internal protection in a
+	safe interpreter already. [Tk Bug 521560]
+
+2002-02-22  Miguel Sofer  <msofer@users.sourceforge.net>
+
+	* generic/tclCompCmds: [FR 465811]. Optimising [if], [for] and [while]
+	for constant conditions; in addition, [for] and [while] are now
+	compiled with the "loop rotation" optimisation (thanks to Kevin
+	Kenny).
+
+2002-02-22  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	--- TIP#76 CHANGES ---
+	* generic/tclCmdMZ.c (Tcl_RegsubObjCmd): Final-argument-less
+	[regsub] returns the modified string.
+	* doc/regsub.n: Updated docs.
+	* tests/regexp.test: Updated and added tests.
+
+	* compat/strtoll.c (strtoll):
+	* compat/strtoull.c (strtoull):
+	* unix/tclUnixPort.h:
+	* win/tclWinPort.h: Const-ing 64-bit compatability declarations. Note
+	that the return pointer is non-const because it is entirely legal for
+	the functions to be called from somewhere that owns the string being
+	passed. Fixes problem reported by Larry Virden.
+
+2002-02-21  David Gravereaux <davygrvy@pobox.com>
+
+	* win/mkd.bat (removed):
+	* win/coffbase.txt (new):
+	* win/makefile.bc:
+	* win/makefile.vc:  Changed the 'setup' target to stop using the
+	mkd.bat file and just make the directory right in the rule. Same
+	change to makefile.bc. Neither configure.in nor Makefile.in use it.
+
+	coffbase.txt will be the master list for our "prefered base addresses"
+	set by the linker. This should improve load-time (NT only) by avoiding
+	relocations. Submissions to the list by extension authors are
+	encouraged.
+
+	Added a 'tidy' target to compliment 'clean' and 'hose' to remove just
+	the outputs. Also removed the $(winlibs) macro as it wasn't being
+	used.
+
+	Stuff left to do:
+	1) get the winhelp target to stop building in the tools/ directory.
+	2) stop using rmd.bat
+	3) add more dependacy rules.
+
+	* win/tclAppInit.c:  Reverted back to -r1.6, as the header file change
+	to tclPort.h won't allow for easy embedded support outside of the
+	source dist. Thanks to Don Porter for pointing this out to me.
+
+2002-02-21  David Gravereaux <davygrvy@pobox.com>
+
+	* win/makefile.vc:
+	* win/rules.vc:  Added a new "loimpact" option that sets the
+	-ws:aggressive linker option. Off by default. It's said to keep the
+	heap use low at the expense of alloc speed.
+
+	* win/tclAppInit.c: Changed #include "tcl.h" to be tclPort.h to remove
+	the raw windows.h include. tclPort.h brings in windows.h already and
+	lessens the pre-compiled-header mush and the randomly useless #pragma
+	comment (lib,...) references throughout the big windows.h tree (as
+	observed at high linker warning levels).
+
+2002-02-21  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tcl.h: Better guessing of LP64/ILP32 architecture, but now
+	sensitive to presence of (suitable) <limits.h>
+
+2002-02-20  Don Porter <dgp@users.sourceforge.net>
+
+	* generic/tcl.decls (Tcl_RegExpRange,Tcl_GetIndexFromObjStruct):
+	Overlooked a few source incompatibilities. Now using CONST84.
+	* generic/tclDecls.h: make genstubs
+	* generic/tcl.h (Tcl_CmdObjTraceProc): silence warning from Sun
+	Workshop compiler.
+
+2002-02-20  David Gravereaux <davygrvy@pobox.com>
+
+	* win/buildall.vc.bat:
+	* win/makefile.vc:
+	* win/rules.vc: General clean-ups. Added compiler and linker tests for
+	a) the pentium 0x0F errata, b) optimizing (not all have this), and c)
+	linker v6 section alignment confusion. All these are tested first to
+	make sure any D4002 or LNK1117 warnings aren't displayed. The pentium
+	0x0F errata is a recommended switch. The v5 linker's section alignment
+	default is 512, but the v6 linker was changed to 4096 in an attempt to
+	speed loading on Win98. I changed the default to always be 512 across
+	both linkers, unless linking statically, then 4096 is used for the
+	claimed speed effect. Using a 512 alignment saves 12k bytes of dead
+	space in the DLL.
+
+	Added IA64 B-stepping errata switch when the compiler supports it.
+
+	Added profiling to $(lflags) when requested and also removed the
+	explict -entry option as the default works fine as is.
+
+	Removed win/tclWinInit.c from the special case section to let it use
+	the common implicit rule as the $(EXTFLAGS) macro it had was never
+	referenced anywhere.
+
+2002-02-20  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tcl.h: Added code to guess the correct settings for
+	TCL_WIDE_INT_IS_LONG and TCL_WIDE_INT_TYPE when configure doesn't tell
+	us them, as can happen with extensions.
+
+2002-02-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/format.n: Updated docs to list the specification.
+	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Made behaviour on 64-bit
+	platforms correctly meet the specification, that %d works with the
+	native word-sized integer, instead of trying to guess (wrongly)
+	from the value being passed.
+
+2002-02-19  Don Porter <dgp@users.sourceforge.net>
+
+	* changes: First draft of updated changes for 8.4a4 release.
+
+2002-02-15  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* unix/tclUnixPort.h: add strtoll/strtoull declarations for
+	platforms that do not define them.
+
+	* generic/tclIndexObj.c (STRING_AT): removed ptrdiff_t cast and
+	use of VOID* in default case (GNU-ism).

+	regarding _stati64
+
+2002-02-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	+----------------------+
+	| TIP #72 IMPLEMENTED. |
+	+----------------------+
+
+	There are a lot of changes from this TIP, so please see
+	http://purl.org/tcl/tip/72.html for discussion of
+	backward-compatability issues, but the main ones modifications are in:
+
+	* generic/tcl.h: New types.
+	* generic/tcl.decls: New public functions.
+	* generic/tclExecute.c: 64-bit aware bytecode engine.
+	* generic/tclBinary.c: 64-bit handling in [binary] command.
+	* generic/tclScan.c: 64-bit handling in [scan] command.
+	* generic/tclCmdAH.c: 64-bit handling in [file] and [format]
+	commands.
+	* generic/tclBasic.c: New "wordSize" entry in ::tcl_platform.
+	* generic/tclFCmd.c: Large-file support (with many consequences.)
+	* generic/tclIO.c: Large-file support (with many consequences.)
+	* compat/strtoll.c, compat/strtoull.c: New support functions.
+	* unix/tcl.m4, unix/configure: 64-bit support and greatly enhanced
+	cacheing.
+
+	Most other changes, including all those in doc/* and test/* as well as
+	the majority in the platform directories, follow on from these.
+
+	Also coming out of the woodwork:
+	* generic/tclIndex.c: Better support for Cray PVP.
+	* win/tclWinMtherr.c: Better Borland support.
+
+	Note that, in a number of places through the Unix part of the platform
+	support, there are Tcl_Platform* references. These are expanded into
+	the correct way to call that particular underlying function, i.e. with
+	or without a '64' suffix, and should be used by people working on the
+	core in preference to the API functions they overlay so that the code
+	remains portable depending on the presence or absence of 64-bit
+	support on the underlying platform.
+
+	***POTENTIAL INCOMPATIBILITY***: Extracted from the TIP
+
+	SUMMARY OF INCOMPATIBILITIES AND FIXES
+	======================================
+
+	The behaviour of expressions containing constants that appear positive
+	but which have a negative internal representation will change, as
+	these will now usually be interpreted as wide integers. This is always
+	fixable by replacing the constant with int(constant).
+
+	Extensions creating new channel types will need to be altered as
+	different types are now in use in those areas. The change to the
+	declaration of Tcl_FSStat and Tcl_FSLstat (which are the new preferred
+	API in any case) are less serious as no non-alpha releases have been
+	made yet with those API functions.
+
+	Scripts that are lax about the use of the l modifier in format and
+	scan will probably need to be rewritten. This should be very uncommon
+	though as previously it had absolutely no effect.
+
+	Extensions that create new math functions that take more than one
+	argument will need to be recompiled (the size of Tcl_Value changes),
+	and functions that accept arguments of any type (TCL_EITHER) will need
+	to be rewritten to handle wide integer values. (I do not expect this
+	to affect many extensions at all.)
+
+2002-02-14  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* generic/tclIOCmd.c (Tcl_GetsObjCmd): Trivial fix for [Bug 517503], a
+	memory leak reported by Miguel Sofer <msofer@users.sf.net>. The leak
+	happens if an error occurs for "set var [gets $chan]" and leak one
+	empty object.
+
+2002-02-12  David Gravereaux <davygrvy@pobox.com>
+
+	* djgpp/ (new directory)
+	* djgpp/Makefile (new):
+	* unix/tclAppInit.c:
+	* unix/tclMtherr.c:
+	* unix/tclUnixFCmd.c:
+	* unix/tclUnixFile.c:
+	* unix/tclUnixInit.c:
+	* unix/tclUnixPort.h:  Early stage of DJGPP support for building Tcl
+	on DOS. Dynamic loading isn't working, yet. Requires watt32 for the
+	TCP/IP stack. No autoconf, yet. Barely tested, but makes a working exe
+	that runs Tcl in protected-mode, flat memory. [exec] and pipes will
+	need the most work as multi-tasking on DOS has to be carefully.
+
+2002-02-10  Kevin Kenny  <kennykb@acm.org>

+	Tcl_GetCommandInfoFromToken and Tcl_SetCommandInfoFromToken.
+	(TIPs #32 and #79.)
+
+	* generic/tclDecls.h:
+	* generic/tclStubInit.c: Regenerated Stubs tables.
+
+2002-02-08  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* unix/configure:
+	* unix/tcl.m4: added -pthread for FreeBSD to EXTRA_CFLAGS and
+	LDFLAGS. Also triggered nodots only for FreeBSD-3. Added
+	AC_DEFINE(_POSIX_PTHREAD_SEMANTICS) for Solaris.
+
+	* unix/tclUnixPort.h:
+	* unix/tclUnixThrd.c: added thread-safe versions of readdir,
+	localtime, gmtime and inet_ntoa for threaded build. (jgdavidson)
+
+	* generic/tclScan.c (Tcl_ScanObjCmd): prevented ckfree being called on
+	a pointer to NULL.

+	Tcl_ExternalToUtfDString, Tcl_UtfToExternalDString,
+	Tcl_UniCharToUtfDString, Tcl_GetCwd, Tcl_WinTCharToUtf. Also restored
+	Tcl_WinUtfToTChar to return (TCHAR *) and Tcl_UtfToUniCharDString to
+	return (Tcl_UniChar *). Modified some callers. This change recognizes
+	that Tcl_DStrings are de-facto white-box objects.
+
+	* generic/tclDecls.h:
+	* generic/tclPlatDecls.h: make genstubs
+
+	* generic/tclCmdMZ.c: corrected use of C++-style comment.
+
+2002-02-06  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tests/scan.test:
+	* generic/tclScan.c (Tcl_ScanObjCmd): corrected scan 0x... %x handling
+	that didn't accept the 0x as a prelude to a base 16 number. [Bug
+	495213]
+
+	* generic/tclCompCmds.c (TclCompileRegexpCmd): made early check for
+	bad RE to stop checking further.
+
+	* generic/tclCmdMZ.c (Tcl_RegsubObjCmd): added special case to search
+	for simple 'string map' style regsub calls. Delayed creation of
+	resultPtr object until an initial match is made, as the input string
+	object can then be reused for no matches.
+	(Tcl_StringObjCmd): optimization improvements to the STR_MAP
+	algorithm for zero-length and nocase cases.
+
+	* tests/regexp.test:
+	* tests/regexpComp.test: extra code coverage tests.
+
+	* tests/string.test: added 10.18 and 10.19 extra tests.
+
+	* generic/regc_locale.c (casecmp): slight performance improvement.
+
+2002-02-05  Don Porter <dgp@users.sourceforge.net>
+
+	* library/http/http.tcl:
+	* library/http/pkgIndex.tcl:  Corrected use of http::error when
+	::error was intended. Bump to http 2.4.2.
+
+2002-02-04  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* unix/tclUnixChan.c (FileOutputProc): Fixed [bug 465765] reported by
+	Dale Talcott <daletalcott@users.sourceforge.net>. Avoid writing
+	nothing into a file as STREAM based implementations will consider this
+	a EOF (if the file is a pipe). Not done in the generic layer as this
+	type of writing is actually useful to check the state of a socket.
+
+	* doc/open.n: Fixed [Bug 511540], added cross-reference to 'pid' as
+	the command to use to retrieve the pid of a command pipeline created
+	via 'open'.
+
+2002-02-01  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd): handle quirky about case
+	earlier to avoid shimmering problem.
+
+2002-02-01  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* tests/io.test: io-39.22 split into two tests, one platform
+	dependent, the other not. -eofchar is not empty on the windows
+	platform.
+
+2002-02-01  Vince Darley <vincentdarley@users.sourceforge.net>
+
+	* generic/tclTest.c: fix to picky windows compiler problem with the
+	'MainLoop' function declaration.
+
+2002-01-31  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* win/tclWinFCmd.c: TIP 27: Applied patch fixing CONST warnings on

+
+2002-01-30  Don Porter <dgp@users.sourceforge.net>
+
+	* generic/tcl.decls:
+	* generic/tcl.h:
+	* generic/tclInt.h: For each interface identified in the TIP 27
+	changes below as a POTENTIAL INCOMPATIBILITY, the source of the
+	incompatibility has been parameterized so that it can be removed. When
+	compiling extension code against the Tcl header files, use the
+	compiler flag -DUSE_NON_CONST to remove the irresolvable source
+	incompatibilities introduced by the TIP 27 changes. Resolvable changes
+	are left for extension authors to resolve.
+	* generic/tclDecls.h: make genstubs
+
+2002-01-30  Vince Darley <vincentdarley@users.sourceforge.net>
+
+	* doc/FileSystem.3: added documentation for 3 public functions which
+	had been overlooked. [Bug 507701]
+	* unix/mkLinks: make mklinks
+
+2002-01-29  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tests/regexpComp.test:

+	* win/tclWinReg.c (regConnectRegistryProc,RecursiveDeleteKey)

+	it only throws the error for runtime compile, in case the user
+	modifies 'string'.
+	(TclCompileRegexpCmd): first try at a byte-compiled regexp command. It
+	handles static strings and ^$ bounded static strings.
+	(TclCompileAppendCmd): made TclPushVarName call always use
+	TCL_CREATE_VAR as numWords is always > 2 at that point.
+
+	* generic/tclExecute.c (TclExecuteByteCode:INST_LIST): correct
+	possibly dangerous decr in macro call.
+
+	* win/tclWinInit.c (TclpFindVariable): CONSTification touch-up

+
+	* generic/tclIO.c (WriteChars): Fix for [Bug 506297], reported by
+	Martin Forssen <ruric@users.sourceforge.net>. The encoding chosen in
+	the script exposing the bug writes out three intro characters when
+	TCL_ENCODING_START is set, but does not consume any input as
+	TCL_ENCODING_END is cleared. As some output was generated the
+	enclosing loop calls UtfToExternal again, again with START set. Three
+	more characters in the out and still no use of input ... To break this
+	infinite loop we remove TCL_ENCODING_START from the set of flags after
+	the first call (no condition is required, the later calls remove an
+	unset flag, which is a no-op). This causes the subsequent calls to
+	UtfToExternal to consume and convert the actual input.

+
+	* generic/tclIOCmd.c (Tcl_GetsObjCmd): Fixed [Bug 504642] as reported
+	by Brian Griffin <bgriffin@users.sourceforge.net>, using his
+	patch. Before the patch the generic I/O layer held an unannounced
+	reference to the interp result to store the read line into. This
+	unfortunately has disastrous results if the channel driver executes a
+	tcl script to perform its operation, this freeing the interp
+	result. In that case we are dereferencing essentially a dangling
+	reference. It is not truly dangling because the object is in the free
+	list, but this only causes us to smash the free list and have the
+	error occur later somewhere else. The patch simply creates a new
+	object for the line and later sets it into the interp result when we
+	are done with reading.

+
+2002-01-05  Don Porter <dgp@users.sourceforge.net>
+
+	* doc/Tcl_Main.3:
+	* generic/tclMain.c:  Substantial rewrite and expanded documentation
+	of Tcl_Main to correct a number of bugs and flaws:
+
+	  - Interactive Tcl_Main can now enter a main loop, exit that loop and
+	    continue interactive operations. The loop may even exit in the
+	    midst of interactive command typing without loss of the partial
+	    command. [Bugs 486453, 474131]
+	  - Tcl_Main now gracefully handles deletion of its master
+	    interpreter.
+	  - Interactive Tcl_Main can now operate with non-blocking stdin
+	  - Interactive Tcl_Main can now detect EOF on stdin even in
+	    mid-command. [Bug 491341]
+	  - Added VFS-aware internal routines for managing the startup script
+	    selection.
+	  - Tcl variable 'tcl_interactive' is now linked to C variable 'tty'
+	    so that one can disable/enable interactive prompts at the script
+	    level when there is no startup script. This is meant for use by
+	    the test suite.
+	  - Consistent use of the Tcl libraries standard channels as returned
+	    by Tcl_GetStdChannel(); as opposed to the channels named 'stdin',
+	    'stdout', and 'stderr' in the master interp, which can be
+	    different or unavailable.
+	  - Tcl_Main now calls Tcl_Exit() if evaluation of [exit] in the
+	    master interpreter returns, assuring Tcl_Main does not return.
+	  - Documented Tcl_Main's absence from public stub table
+	  - Documented that Tcl_Main does not return.
+	  - Documented Tcl variables set by Tcl_Main.
+	  - All prompts are done from a single procedure, Prompt.
+	  - Use of Tcl_Obj-enabled interfaces everywhere.
+
+	* generic/tclInt.decls (TclGetStartupScriptPath,
+	(TclSetStartupScriptPath): New internal VFS-aware routines for
+	managing the startup script of Tcl_Main.
+	* generic/tclIntDecls.h:
+	* generic/tclStubInit.c: make genstubs
+
+	* generic/tclTest.c (TestsetmainloopCmd,TestexitmainloopCmd,
+	(Tcltest_Init,TestinterpdeleteCmd):
+	* tests/main.test (new):  Added new file to test suite that thoroughly
+	tests generic/tclMain.c; added some new test commands for testing
+	Tcl_SetMainLoop().

+	to accurately describe when and how they are used. [Bug 497459]
+
+	* generic/tclThreadJoin.c (TclRememberJoinableThread,TclJoinThread):
+	Replaced Tcl_Alloc and Tcl_Free calls with ckalloc and ckfree so that

+
+	* tests/basic.test (basic-39.4): Greatly simplified test while
+	still leaving it so that it crashes when run without the fix to
+	the [foreach] implementation.
+	* generic/tclCmdAH.c (Tcl_ForeachObjCmd): Stopped [Bug 494348] from
+	happening by not trying to be so clever with cacheing; if nothing
+	untoward is happening anyway, the less efficient technique will
+	only add a few instruction cycles (one function call and a few
+	derefs/assigns per list per iteration, with no change in the
+	number of tests) and if something odd *is* going on, the code is
+	now far more robust.

+	match] no longer uses Tcl_StringCaseMatch internally.
+
+	* tests/string.test (string-11.51):
+	* generic/tclUtf.c (Tcl_UniCharCaseMatch):
+	* generic/tclUtil.c (Tcl_StringCaseMatch): Fault with matching
+	case-insensitive non-ASCII patterns containing upper case characters.

+	* doc/file.n: clarify behaviour of 'file link' when the target is not
+	an absolute path.
+	* doc/filename.n: correct documentation to say that Windows Tcl does
+	handle '~user', for recent Windows releases, and clarified distinction
+	between MacOS 'classic' and MacOS X.
+	* doc/glob.n: clarification of glob's behaviour when returning
+	filenames starting with a '~'.
+
+	* tests/fileSystem.test:
+	* tests/fileName.test: new tests added for the normalization problem
+	above and other recentlt reported issues.

+
+2003-12-11  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinSock.c (SocketThreadExitHandler) : added a TerminateThread
+	fallback just in case the socket handler thread is really in a paused
+	state. This can happen when Tcl is being unloaded by the OS from an
+	exception handler. See MSDN docs on DllMain, it states this behavior.

+2003-12-09  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* win/tclWinFile.c: fix to NT file permissions code [Bug 855923]
+	* tests/winFile.test: added tests for NT file permissions - patch and
+	test scripts supplied by Benny.
+
+	* tests/winFCmd.test: fixed one test for when not running in C:/
+
+2003-12-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclBinary.c (DeleteScanNumberCache, ScanNumber): Made the
+	numeric scan-value cache have proper references to the objects within
+	it so strange patterns of writes won't cause references to freed
+	objects. Thanks to Paul Obermeir for the report. [Bug 851747]
+
+2003-12-01  Miguel Sofer <msofer@users.sf.net>

+	and TCL_PARSE_PART1 (deprecated) [Bug 835020]
+
+2003-11-19  Don Porter	<dgp@users.sourceforge.net>
+
+	* tests/compile.test (compile-16.22.0):	Improved test for the recent
+	fix for Bug 845412.
+
+2003-11-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclCompile.c (TclCompileScript): Added a guard for the
+	expansion code so that long non-expanding commands don't get expansion
+	infrastructure inserted in them, especially when that infrastructure
+	isn't initialised. [Bug 845412]
+
+2003-11-18  David Gravereaux <davygrvy@pobox.com>

+	* tests/reg.test: Added tests for [Bugs 230589, 504785, 505048, 840258]
+	recently fixed by 2003-11-15 commit to regcomp.c by Pavel Goran. His
+	notes on the fix: This bug results from an error in code that splits
+	states into "progress" and "no-progress" ones. This error causes an
+	interesting situation with the pre-collected single-linked list of

+
+	* generic/tclTest.c (TestHashSystemHashCmd): Removed 'const' modifier

+	this, we are following in the same footsteps as Tcl_RegisterObjType()

+
+	* generic/tclCmdIL.c (SortInfo,etc): Reorganized so that SortInfo

+	of extracting the string rep.
+
+	* generic/tclStringObj.c (TclAppendLimitedToObj):	New internal
+	routine that supports truncated appends with optional ellipsis marking.
+	This single routine supports UTF-8-safe truncated appends needed in
+	several places throughout the Tcl source code, mostly for error and
+	stack messages. Clean fix for [Bug 760872].

+
+	Fixed [Bug 800106] in which 'glob' was incapable of merging the
+	results of a directory listing (real or virtual) and any virtual
+	filesystem mountpoints in that directory (the latter were ignored).
+	This meant boundaries between different filesystems were not seamless
+	(e.g. 'glob */*' across a filesystem boundary was wrong). Added new
+	entry to Tcl_GlobTypeData in a totally backwards compatible way. To
+	allow listing of mounts, registered filesystems must support the
+	'TCL_GLOB_TYPE_MOUNT' flag. If this is not supported (e.g. in tclvfs
+	1.2) then mounts will simply not be listed for that filesystem.
+
+	Fixed [Bug 749876] 'file writable/readable/etc' (NativeAccess) using
+	correct permission checking code for Windows NT/2000/XP where more
+	complex user-based security/access priveleges are available,
+	particularly on shared volumes. The performance impact of this extra
+	checking will need further investigation. Note: Win 95,98,ME have no
+	support for this.
+
+	Also made better use of normalized rather than translated paths in the
+	platform specific code.
+
+2003-10-12  Jeff Hobbs  <jeffh@ActiveState.com>

+	access to Tcl_NumUtfChars for testing.
+	* generic/tclUtf.c (Tcl_NumUtfChars): Corrected string length

+
+	TIP#123 IMPLEMENTATION BASED ON WORK BY ARJEN MARKUS
+
+	* generic/tclCompile.h (INST_EXPON):		Implementation of
+	* generic/tclCompile.c (tclInstructionTable):	exponential operator.
+	* generic/tclCompExpr.c (operatorTable):
+	* generic/tclParseExpr.c (ParseExponentialExpr, GetLexeme):
+	* generic/tclExecute.c (TclExecuteByteCode, ExponWide, ExponLong):
+	(IllegalExprOperandType):
+	* tests/expr.test:
+	* tests/compExpr-old.test:
+	* doc/expr.n:
+
+2003-09-10  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/opt/optparse.tcl:	Latest revisions caused [OptGuessType]
+	to guess "int" instead of "string" for empty strings. Missed the
+	required "-strict" option to [string is]. Thanks to Revar Desmera.
+	[Bug 803968]
+
+2003-09-08  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinLoad.c (TclpDlopen): Changed the error message for
+	ERROR_PROC_NOT_FOUND to be a bit more helpful in giving us clues.
+	"can't find specified procedure" means a function in the import table,
+	for implicit loading, couldn't be resolved and that's why the load
+	failed.
+
+2003-09-04  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/Tcl_Main.3:
+	* doc/FileSystem.3:				Implementation of
+	* doc/source.n:					TIPs 137/151. Adds a
+	* doc/tclsh.1:					-encoding option to
+	* generic/tcl.decls:				the [source] command
+	* generic/tclCmdMZ.c (Tcl_SourceObjCmd):	and a new C routine,
+	* generic/tclIOUtil.c (Tcl_FSEvalFileEx):	Tcl_FSEvalFileEx(),
+	* generic/tclMain.c (Tcl_Main):			that provides C access
+	* mac/tclMacResource.c (Tcl_MacSourceObjCmd):	to the same function.
+	* tests/cmdMZ.test:				Also adds command line
+	* tests/main.test:	option handling in Tcl_Main() so that tclsh
+	* tests/source.test:	and other apps built on Tcl_Main() respect a
+	-encoding command line option before a script filename. Docs and tests
+	updated as well. [Patch 742683]
+	This is a ***POTENTIAL INCOMPATIBILITY*** only for those C programs
+	that embed Tcl, build on Tcl_Main(), and make use of Tcl_Main's former
+	ability to pass a leading "-encoding" option to interactive shell
+	operations.
+
+	* generic/tclInt.decls:				Added internal stub
+	* generic/tclMain.c (Tcl*StartupScript*):	table entries for two
+	new functions Tcl_SetStartupScript() and Tcl_GetStartupScript() that
+	set/get the path and encoding for the startup script to be evaluated
+	by either Tcl_Main() or Tk_Main(). Given public names in anticipation
+	of their exposure by a followup TIP.
+
+	* generic/tclDecls.h:		make genstubs
+	* generic/tclIntDecls.h:
+	* generic/tclStubInit.c:
+
+2003-09-04  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/SplitList.3:	Implementation of TIP 148.  Fixes [Bug 489537].
+	* generic/tcl.h:	Updated Tcl_ConvertCountedElement() to quote
+	* generic/tclUtil.c:	the leading "#" character of all list elements
+	unless the TCL_DONT_QUOTE_HASH flag is passed in.
+
+	* generic/tclDictObj.c:	Updated Tcl_ConvertCountedElement() callers
+	* generic/tclListObj.c:	to pass in the TCL_DONT_QUOTE_HASH flags
+	* generic/tclResult.c:	when appropriate.
+
+2003-08-31  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/return.n:	Updated [return] docs to cover new TIP 90 features.
+
+	* doc/break.n:		Added SEE ALSO references to return.n
+	* doc/continue.n:
+
+2003-09-01  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/Namespace.3: Basic documentation for the TIP#139 functions. This
+	will need improving, but the basic bits are there at least.
+
+2003-08-31  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/catch.n:	Updated [catch] docs to cover new TIP 90 features.
+
+2003-08-29  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclCmdAH.c:	Corrected bug in TIP 90 implementation where
+	* tests/cmdMZ.test:	the default -errorcode NONE value was not
+	copied into the return options dictionary. This correction modified
+	one test result.
+
+2003-08-27  David Gravereaux <davygrvy@pobox.com>
+
+	* compat/strftime.c (_fmt): Removed syst array intializer that
+	couldn't take variables within it under the watcom compiler:
+	'Initializers must be constant'. I believe Borland has this strictness
+	as well. VC++ must be non-standard about this.
+
+	Changed Win32 platform #ifdef from 'WIN32' to '__WIN32__' as this is
+	the correct one to use across the Tcl sources. Even though we do force
+	it in tcl.h, the true parent one is __WIN32__.
+
+	Added missing CONST'ification usage to match prototype listed in
+	tclInt.decls.
+
+	* win/tclWinPort.h:  Added a block for OpenWatcom adjustments that
+	fixes 1) the same issue Mo did for MinGW lack of missing LPFN_*
+	typedefs in their WINE derived <winsock2.h> and 2) The need to be
+	strict about how the char type needs to be signed by default.
+
+	* win/tclWinSock.c:  Added OpenWatcom to the commentary about the
+	#ifdef HAVE_NO_LPFN_DECLS block.
+
+	* win/tclWinTime.c:  Changed use of '_timezone' to 'timezone' as this
+	difference is already adjusted for in tclWinPort.h. Removed
+	unreferenced posixEpoch file-scope global.
+
+	* win/tclWinFile.c (WinReadLinkDirectory): Fix for 'Initializers must
+	be constant' with the driveSpec array using OpenWatcom.
+
+2003-08-27  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclUtil.c:	Corrected [Bug 411825] and other bugs in
+	TclNeedSpace() where non-breaking space (\u00A0) and backslash-escaped
+	spaces were handled incorrectly.
+	* tests/util.test:	Added new tests util-8.[2-6].
+
+2003-08-26  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tcl.h: Added some support for the LCC-Win32 compiler.
+	Unfortunetly, this compiler has a bug in its preprocessor and can't
+	build Tcl even with this minor patch. Also added some support for the
+	OpenWatcom compiler. A new win/makefile.wc to follow soon.
+
+2003-08-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tools/genStubs.tcl (genStubs::makeDecl): A more subtle way of
+	generating stubbed declarations allows us to have declarations of a
+	function in multiple interfaces simultaneously.
+
+	* generic/tcl.decls: Duplicated some namespace declarations from
+	tclInt.decls here, as mandated by TIP #139. This is OK since the
+	declarations match and will end up using the declarations in the
+	public code from now on because of #include ordering. Keeping the old
+	declarations in tclInt.decls; there's no need to gratuitously break
+	compatability for those extensions which are already clients of the
+	namespace code.
+
+2003-08-23  Zoran Vasiljevic  <zoran@archiwrae.com>
+
+	* generic/tclIOUtil.c: merged fixes for thread-unsafe handling of
+	filesystem records [Bug 753315]. This also fixed the [Bug 788780]
+	* generic/tclPathObj.c: merged fixes for thread-unsafe handling of
+	filesystem records. [Bug 753315]
+
+	* generic/tclFileSystem.h: merged fixes for thread-unsafe handling of
+	filesystem records. [Bug 753315]
+
+2003-08-19  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* win/tclWinSerial.c (SerialErrorStr): Fixed a syntax error created in
+	the previous code cleanup.
+
+2003-08-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* win/tclWinSerial.c: Adjusted commenting and spacing usage to follow
+	the principles of the Style Guide better.
+
+2003-08-18  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure: Regen.
+	* win/tcl.m4 (SC_ENABLE_SYMBOLS): Use test instead of -eq, which does
+	not work. [Bug 781109]
+
+2003-08-13  Chengye Mao <chengye.geo@yahoo.com>
+
+	* win/tclWinPipe.c: fixed a bug in BuildCommandLine. This bug built a
+	command line with a missing space between tclpipe.dll and the
+	following arguments. It caused error in Windows 98 when exec
+	command.com (e.g. dir). [Bug 789040]
+
+2003-08-11  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	TIP #136 IMPLEMENTATION from Simon Geard <simon.geard@ntlworld.com>
+	* generic/tclCmdIL.c (Tcl_LrepeatObjCmd): Adapted version of Simon's
+	* doc/lrepeat.n:			  patch, updated to the HEAD
+	* tests/lrepeat.test:			  and matching the core style.
+	* generic/tclBasic.c (buildIntCmds):	Splice into core.
+	* generic/tclInt.h:
+	* doc/list.n:				Cross-reference.
+
+2003-08-06  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/tclWinInit.c: recognize amd64 and ia32_on_win64 cpus.
+
+2003-08-06  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/msgcat/msgcat.tcl:	Added escape so that non-Windows
+	* library/msgcat/pkgIndex.tcl:	platforms do not try to use the
+	registry package. This can save a costly and pointless package search.
+	Bumped to 1.3.1. Thanks to Dave Bodenstab. [Bug 781609]
+
+2003-08-05  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c (INST_INVOKE, INST_EVAL, INST_PUSH_RESULT):
+	added a Tcl_ResetResult(interp) at each point where the interp's
+	result is pushed onto the stack, to avoid keeping an extra reference
+	that may cause costly Tcl_Obj duplication. Detected by Franco Violi,
+	analyzed by Peter Spjuth and Donal Fellows. [Bug 781585]
+
+2003-07-28  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* doc/FileSystem.3:
+	* doc/Translate.3: better documentation of Tcl_TranslateFileName and
+	related functions. [Bug 775220]
+
+2003-07-24  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tcl.h: Revert change made on 2003-07-21 since it made the
+	sizeof(Tcl_Obj) different for regular vs mem debug builds.
+	* generic/tclInt.h: Define TclDecrRefCount in terms of
+	Tcl_DbDecrRefCount which removes one layer of inderection.
+	* generic/tclObj.c (TclDbInitNewObj, Tcl_DbIncrRefCount,
+	(Tcl_DbDecrRefCount, Tcl_DbIsShared): Define ThreadSpecificData that
+	contains a hashtable. The table is used to ensure that a Tcl_Obj is
+	only acted upon in the thread that allocated it. This checking code is
+	enabled only when mem debug and threads are enabled.
+
+2003-07-24  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/async.test:	Added several tests that demonstrate [Bug
+	* tests/basic.test:	489537], Tcl's longstanding failure to
+	* tests/dict.test:	properly quote any leading '#' character when
+	* tests/dstring.test:	generating the string rep of a list so that
+	* tests/list.test:	the comment-power of that character is hidden
+	* tests/parse.test:	from any [eval], in order to satisfy the
+	* tests/util.test:	documentation that [list] does [eval]-safe
+				quoting.
+
+2003-07-24  Reinhard Max  <max@suse.de>
+
+	* library/package.tcl: Fixed a typo that broke pkg_mkIndex -verbose.
+	* tests/pkgMkIndex.test: Added a test for [pkg_mkIndex -verbose].
+
+	* ChangeLog.2002 (new file):
+	* ChangeLog: broke changes from 2002 into ChangeLog.2002 to reduce
+	size of the main ChangeLog.
+
+2003-07-23  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/Makefile.in: changes to html-tcl & html-tk targets for
+	compatibility with non-gnu makes.
+
+	* unix/Makefile.in: added macosx/README to dist target.
+
+2003-07-23  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* win/tclWinReg.c (OpenSubKey): Fixed bug 775976 which causes the
+	registry set command to fail when built with VC7.
+	* library/reg/pkgIndex.tcl: Incremented the version to 1.1.2.
+
+2003-07-21  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	Check that the thread incrementing or decrementing the ref count of a
+	Tcl_Obj is the thread that originally allocated the thread. This fail
+	fast behavior will catch programming errors that allow a single
+	Tcl_Obj to be accessed from multiple threads.
+
+	* generic/tcl.h (Tcl_Obj): Add allocThread member to Tcl_Obj. This
+	member records the thread id the Tcl_Obj was allocated. It is used to
+	check that any future ref count incr or decr is done from the same
+	thread that allocated the Tcl_Obj. This member is defined only when
+	threads and mem debug are enabled.
+	* generic/tclInt.h (TclNewObj, TclDbNewObj, TclDecrRefCount):
+	Define TclNewObj and TclDbNewObj using TclDbInitNewObj when mem debug
+	is enabled. This fixes a problem where TclNewObj calls did not work
+	the same as TclDbNewObj when mem debug was enabled.
+	* generic/tclObj.c (TclDbInitNewObj, Tcl_DbIncrRefCount,
+	(Tcl_DbDecrRefCount): Add new helper to init Tcl_Obj members when mem
+	debug is enabled. Init the allocThread member in TclDbInitNewObj and
+	check it in Tcl_DbIncrRefCount and Tcl_DbDecrRefCount to make sure a
+	Tcl_Obj allocated in one thread is not being acted upon in another
+	thread.
+
+2003-07-21  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* test/cmdAH.test: ensure certain tests run in local filesystem. [Bug
+	748960]
+
+2003-07-18  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/Makefile: added option to allow installing manpages in
+	addition to default html help.
+
+2003-07-18  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/Utf.3: Tightened up documentation of Tcl_UtfNext and Tcl_UtfPrev
+	to better match the behaviour. [Bug 769895]
+
+2003-07-18  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* library/http/pkgIndex.tcl: upped to http v2.4.4
+	* library/http/http.tcl: add support for user:pass info in URL.
+	* tests/http.test:       [Bug 759888] (shiobara)
+
+2003-07-18  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/tcltest.n:                Restored the [Eval] proc to replace
+	* library/tcltest/tcltest.tcl:  the [::puts] command when either the
+	-output or -error option for [test] is in use, in order to capture
+	data written to the output or error channels for comparison against
+	what is expected.  This is easier to document and agrees better with
+	most user expectations than the previous attempt to replace [puts]
+	only in the caller's namespace.  Documentation made more precise on
+	the subject.  [Bug 706359]
+
+	* doc/AddErrInfo.3:	Improved consistency of documentation by
+	* doc/CrtTrace.3:      	using "null" everywhere to refer to the
+	* doc/Encoding.3:      	character '\0', and using "NULL" everywhere
+	* doc/Eval.3:          	to refer to the value of a pointer that points
+	* doc/GetIndex.3:      	to nowhere. Also dropped references to ASCII
+	* doc/Hash.3:          	that are no longer true, and standardized on
+	* doc/LinkVar.3:       	the hyphenated spelling of "null-terminated".
+	* doc/Macintosh.3:
+	* doc/OpenFileChnl.3:
+	* doc/SetVar.3:
+	* doc/StringObj.3:
+	* doc/Utf.3:
+
+	* doc/CrtSlave.3 (Tcl_MakeSafe):  Removed warning about possible
+	deprecation (no TIP on that).
+
+2003-07-17  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tclUnixFCmd.c: fix for compilation errors on platforms where
+	configure detects non-functional chflags(). [Bug 748946]
+
+	* macosx/Makefile: Rewrote buildsystem for Mac OS X framework build
+	to be purely make driven; in order to become independent of Apple's
+	closed-source IDE and build tool. The changes are intended to be
+	transparent to the Makefile user, all existing make targets and cmd
+	line variable overrides should continue to work. Changed build to only
+	include tcl specific html help in Tcl.framework, the tk specific html
+	help is now included in Tk.framework. Added var to allow overriding of
+	tclsh used during html help building (Landon Fuller).
+
+	* macosx/Tcl.pbproj/project.pbxproj:
+	* macosx/Tcl.pbproj/jingham.pbxuser: Changed to purely call through to
+	the make driven buildsystem; Tcl.framework is no longer assembled by
+	ProjectBuilder.
+	Set default SYMROOT in target options to simplify setting up PB
+	(manually setting common build folder for tcl & tk no longer needed).
+
+	* tools/tcltk-man2html.tcl: Added options to allow building only the
+	tcl or tk html help files; the default behaviour with none of the new
+	options is to build both, as before.
+
+	* unix/Makefile.in: Added targets for building only the tcl or tk help
+
+	* macosx/README (new): Tcl specific excerpts of tk/macosx/README.
+
+	* generic/tcl.h: Updated reminder comment about editing
+	macosx/Tcl.pbproj/project.pbxproj when version number changes.
+
+2003-07-16  Mumit Khan  <khan@nanotech.wisc.edu>
+
+	* generic/tclPathObj.c (SetFsPathFromAny): Add Cygwin specific code to
+	convert POSIX filename to native format.
+	* generic/tclFileName.c (Tcl_TranslateFileName): And remove from here.
+	(TclDoGlob): Adjust for cygwin and append / for dirs instead of \
+	* win/tclWinFile.c (TclpObjChdir): Use chdir on Cygwin.
+	[Patch 679315]
+
+2003-07-16  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* library/safe.tcl (FileInAccessPath): normalize paths before
+	comparison. [Bug 759607] (myers)
+
+	* unix/tclUnixNotfy.c (NotifierThreadProc): correct size of found and
+	word vars from int to long. [Bug 767578] (hgo)
+
+	* generic/tcl.h:       Add recognition of -DTCL_UTF_MAX=6 on the make
+	* generic/regcustom.h: line to support UCS-4 mode. No config arg at
+	this time, as it is not the recommended build mode.
+
+	* generic/tclPreserve.c: In Result and Preserve'd routines, do not
+	* generic/tclUtil.c:     assume that ckfree == free, as that is not
+	* generic/tclResult.c:   always true. [Bug 756791] (fuller)
+
+2003-07-16  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/CrtSlave.3 (Tcl_MakeSafe): Updated documentation to strongly
+	discourage use. IMHO code outside the core that uses this function is
+	a bug... [Bug 655300]
+
+2003-07-16  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclFileName.c (Tcl_GlobObjCmd):	[Bug 771840]
+	* generic/tclPathObj.c (Tcl_FSConvertToPathType):[Bug 771947]
+	* unix/tclUnixFCmd.c (GetModeFromPermString):	[Bug 771949]
+	Silence compiler warnings about unreached lines.
+
+	* library/tcltest/tcltest.tcl (ProcessFlags):	Corrected broken call
+	* library/tcltest/pkgIndex.tcl:			to [lrange]. Bumped to
+	version 2.2.4. [Bug 772333]
+
+2003-07-15  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/dltest/pkga.c (Pkga_EqObjCmd): Fix typo that was causing a
+	crash in load.test.
+
+2003-07-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/array.n: Make sure docs are synched with the 8.4 release.
+
+2003-07-15  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/http.n:  Updated SYNOPSIS to match actual syntax of commands.
+	[Bug 756112]
+
+	* unix/dltest/pkga.c:	Updated to not use Tcl_UtfNcmp and counted
+	strings instead of strcmp (not defined in any #include'd header) and
+	presumed NULL-terminated strings.
+
+	* generic/tclCompCmds.c (TclCompileIfCmd):  Prior fix of Bug 711371 on
+	2003-04-07 introduced a buffer overflow. Corrected. [Bug 771613]
+
+2003-07-15  Kevin B. Kenny  <kennykb@acm.org>
+
+	* win/rules.vc: Added a missing $(OPTDEFINES) which broke the build if
+	STATS=memdbg was specified.
+
+2003-07-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclCmdIL.c (SortCompare): Cleared up confusing error
+	message. [Bug 771539]
+
+2003-07-11  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/binary.test (binary-46.*): Tests to help enforce the current
+	behaviour.
+	* doc/binary.n: Documented that [binary format a] and [binary scan a]
+	do encoding conversion by dropping high bytes, unlike the rest of the
+	core. [Bug 735364]
+
+2003-07-11  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/package.tcl:  Corrected [pkg_mkIndex] bug reported on
+	comp.lang.tcl. The indexer was searching for newly indexed packages
+	instead of newly provided packages.
+
+2003-07-08  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* tests/winFCmd.test: fix for five tests under win98 [Bug 767679]
+
+2003-07-07  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* doc/array.n: add examples from Welton
+
+2003-06-23  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* doc/file.n: clarification of 'file tail' behaviour [Bug 737977]
+
+2003-07-04  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/expr.n: Tighten up the wording of some operations. [Bug 758488]
+
+	* tests/cmdAH.test: Made tests of [file mtime] work better on FAT
+	filesystems. [Patch 760768]  Also a little general cleanup.
+
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Made [string map] accept
+	dictionaries for maps.  This is much trickier than it looks, since map
+	entry ordering is significant. [Bug 759936]
+
+	* generic/tclVar.c (Tcl_ArrayObjCmd, TclArraySet): Made [array get]
+	and [array set] work with dictionaries, producing them and consuming
+	them. Note that for compatability reasons, you will never get a dict
+	from feeding a string literal to [array set] since that alters the
+	trace behaviour of "multi-key" sets. [Bug 759935]
+
+2003-06-23  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclTrace.c: fix to Window debug build compilation error.
+
+2003-06-27  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/init.test: Added [cleanupTests] to report results of tests
+	* tests/pkg.test:  that run in slave interps.  [Bugs 761334,761344]
+
+	* tests/http.test: Used more reliable path to find httpd script.

+2003-06-25  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/configure: Regen.

+
+	* generic/tclObj.c (tclCmdNameType):  Converted internal rep
+	management of the cmdName Tcl_ObjType the opposite way, to always use
+	the twoPtrValue instead of always using the otherValuePtr. Previous
+	fix on 2003-05-12 broke several extensions that wanted to poke around
+	with the twoPtrValue.ptr2 value of a cmdName Tcl_Obj, like TclBlend

+2003-05-22  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/Tcl.pbproj/project.pbxproj: added missing references to new
+	source files tclPathObj.c and tclMacOSXFCmd.c.
+
+	* macosx/tclMacOSXBundle.c: fixed a problem that caused only the first
+	call to Tcl_MacOSXOpenVersionedBundleResources() for a given bundle
+	identifier to succeed. This caused the tcl runtime library not to be
+	found in all interps created after the inital one.
+
+2003-05-19  Kevin B. Kenny  <kennykb@hippolyta>
+
+	* unix/tclUnixTime.c: Corrected a bug in conversion of non-ASCII
+	chars in the format string.
+
+2003-05-19  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/Tcl.pbproj/project.pbxproj: changed tclConfig.sh location in

+	version specific.
+
+	* unix/tclUnixTime.c: fixed typo.
+
+2003-05-18  Kevin Kenny  <kennykb@acm.org>
+
+	* compat/strftime.c:  Modified TclpStrftime to return its result in
+	* generic/tclClock.c: UTF-8 encoding, and removed the conversion from

+
+	* library/dde/pkgIndex.tcl:  Applied TIP #130 which provides for

+
+2003-05-15  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/tclWinFile.c (TclpMatchInDirectory): revert glob code to r1.44

+
+	* doc/socket.n: nroff font handling correction
+
+	* library/encoding/gb2312-raw.enc (new): This is the original
+	gb2312.enc renamed to allow for it to still be used. This is needed by
+	Tk (unix) because X fonts with gb2312* charsets really do want the
+	original gb2312 encoding. [Bug 557030]
+
+2003-05-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Stop unwarranted demotion of

+
+2003-05-14  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* library/encoding/gb2312.enc: copy euc-cn.enc over original
+	gb2312.enc. gb2312.enc appeared to not work as expected, and most uses
+	of gb2312 really mean euc-cn (which may be the cause of the problem).
+	[Bug 557030]
+
+2003-05-14  Daniel Steffen  <das@users.sourceforge.net>
+
+	Implementation of TIP 118:
+
+	* generic/tclFCmd.c (TclFileAttrsCmd): return the list of attributes
+	that can be retrieved without error for a given file, instead of
+	aborting the whole command when any error occurs.
+
+	* unix/tclUnixFCmd.c: added support for new file attributes and for
+	copying Mac OS X file attributes & resource fork during [file copy].
+
+	* generic/tclInt.decls: added declarations of new external commands
+	needed by new file attributes support in tclUnixFCmd.c.
+
+	* macosx/tclMacOSXFCmd.c (new): Mac OS X specific implementation of
+	new file attributes and of attribute & resource fork copying.

+
+	* unix/configure.in: check for APIs needed by new file attributes.

+
+	* tools/genStubs.tcl: fixes to completely broken code trying to

+
+	* tests/unixFCmd.test: added tests of -readonly attribute.
+
+	* tests/macOSXFCmd.test (new): tests of macosx file attributes and of
+	preservation of attributes & resource fork during [file copy].
+
+	* tests/macFCmd.test: restore -readonly attribute of test dir, as
+	otherwise its removal can fail on unices supporting -readonly.
+
+2003-05-13  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tclEnv.c: Another putenv() copy behavior problem repaired
+	when compiling on windows and using microsoft's runtime. [Bug 736421]
+
+2003-05-13  Jeff Hobbs  <jeffh@ActiveState.com>
+

+2003-05-13  Joe Mistachkin  <joe@mistachkin.com>
+
+	* generic/tcl.decls:  Changed Tcl_JoinThread parameter name from

+	* win/tclWinThrd.c:
+	* mac/tclMacThrd.c:
+
+2003-05-13  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tcl.decls:
+	* macosx/tclMacOSXBundle.c: added extended version of the
+	Tcl_MacOSXOpenBundleResources() API taking an extra version number
+	argument: Tcl_MacOSXOpenVersionedBundleResources(). This is needed to
+	be able to access bundle resources in versioned frameworks such as Tcl
+	and Tk, otherwise if multiple versions were installed, only the latest
+	version's resources could be accessed. [Bug 736774]
+
+	* unix/tclUnixInit.c (Tcl_MacOSXGetLibraryPath): use new versioned
+	bundle resource API to get tcl runtime library for TCL_VERSION. [Bug
+	736774]
+
+	* generic/tclPlatDecls.h:
+	* generic/tclStubInit.c: regen.
+
+	* unix/tclUnixPort.h: worked around the issue of realpath() not
+	being thread-safe on Mac OS X by defining NO_REALPATH for threaded
+	builds on Mac OS X. [Bug 711232]
+
+2003-05-12  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/cmdAH.test: General clean-up of tests so that all
+	tcltest-specific commands are protected by constraints and all
+	platforms see the same number of tests. [Bug 736431]
+
+2003-05-12  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclInterp.c: (AliasObjCmd):   Added refCounting of the words
+	* tests/interp.test (interp-33.1):      of the target of an interp
+	alias during its execution. Also added test. [Bug 730244]
+
+	* generic/tclBasic.c (TclInvokeObjectCommand):  objv[argc] is no
+	longer set to NULL (Tcl_CreateObjCommand docs already say that it
+	should not be accessed).
+
+	* tests/cmdMZ.test:  Forgot to import [temporaryDirectory].
+
+	* generic/tclObj.c (tclCmdNameType):  Corrected variable use of the
+	otherValuePtr or the twoPtrValue.ptr1 fields to store a
+	(ResolvedCmdName *) as the internal rep. [Bug 726018]
+
+	* doc/Eval.3:  Corrected prototype for Tcl_GlobalEvalObj [Bug 727622].
+
+2003-05-12  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclVar.c (TclObjLookupVar): [Bug 735335] temporary fix,
+	disabling usage of tclNsVarNameType.

+
+2003-05-10  Jeff Hobbs  <jeffh@ActiveState.com>

+	Windows serial port [Bug 718002] (schroedter)
+
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): prevent string repeat crash
+	when overflow sizes were given (throws error). [Bug 714106]
+
+2003-05-09  Joe Mistachkin <joe@mistachkin.com>
+
+	* generic/tclThreadAlloc.c (TclFreeAllocCache): Fixed memory leak
+	caused by treating cachePtr as a TLS index. [Bug 731754]
+
+	* win/tclAppInit.c (Tcl_AppInit): Fixed memory leaks caused by not
+	freeing the memory allocated by setargv and the async handler created
+	by Tcl_AppInit. An exit handler has been created that takes care of
+	both leaks. In addition, Tcl_AppInit now uses ckalloc instead of
+	Tcl_Alloc to allow for easier leak tracking and to be more consistent
+	with the rest of the Tcl core. [Bugs 733156, 733221]
+
+	* tools/encoding/txt2enc.c (main): Fixed memory leak caused by failing
+	to free the memory used by the toUnicode array of strings [Bug 733221]
+
+2003-05-09  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCompile.c (TclCompileScript):
+	* tests/compile.test (compile-3.5): corrected wrong test and
+	behaviour in the earlier fix for [Bug 705406]; Don Porter reported
+	this as [Bug 735055], and provided the solution.
+
+2003-05-09  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclCmdMZ.c (Tcl_ReturnObjCmd): The array of strings passed
+	to Tcl_GetIndexFromObj must be NULL terminated. [Bug 735186]
+	Thanks to Joe Mistachkin for spotting this.
+
+2003-05-07  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/trace.n: Fixed very strange language in the documentation for
+	'trace add execution'. [Bug 729821]
+
+	* generic/tclCmdMZ.c (Tcl_TraceObjCmd): Made error message for 'trace
+	info' more consistent with documentation. [Bug 706961]
+
+	* generic/tclDictObj.c (DictInfoCmd): Fixed memory leak caused by
+	confusion about string ownership.  [Bug 731706]
+
+2003-05-05  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:		Implementation of TIP 90, which
+	* generic/tclCmdAH.c:		extends the [catch] and [return]
+	* generic/tclCompCmds.c:	commands to enable creation of a
+	* generic/tclExecute.c:		proc that is a replacement for

+	* tests/cmdAH.test:
+	* tests/cmdMZ.test:
+	* tests/error.test:

+
+2003-05-05  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclBasic.c (Tcl_HideCommand): Fixed error message for
+	grammar and spelling.
+
+2003-04-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclDictObj.c (DictIncrCmd): Updated to reflect the behaviour
+	with wide increments of the normal [incr] command.
+	* generic/tclInt.decls: Added TclIncrWideVar2 to internal stub table
+	and cleaned up.
+	* tests/incr.test (incr-3.*):
+	* generic/tclVar.c (TclIncrWideVar2, TclPtrIncrWideVar):
+	* generic/tclExecute.c (TclExecuteByteCode):
+	* generic/tclCmdIL.c (Tcl_IncrObjCmd): Make [incr] work when trying to
+	increment by wide values. [Bug 728838]
+
+	* generic/tclCompCmds.c (TclCompileSwitchCmd): Default mode of
+	operation of [switch] is exact matching. [Bug 727563]
+
+2003-04-25  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:  Tcl_EvalObjv() failed to honor the
+	TCL_EVAL_GLOBAL flag when resolving command names. Tcl_EvalEx passed a
+	string rep including leading whitespace and comments to
+	TclEvalObjvInternal().
+
+2003-04-25  Andreas Kupries  <andreask@activestate.com>
+
+	* win/tclWinThrd.c: Applied SF patch #727271. This patch changes the
+	code to catch any errors returned by the windows functions handling
+	TLS ASAP instead of waiting to get some mysterious crash later on due
+	to bogus pointers. Patch provided by Joe Mistachkin.
+
+	This is a stop-gap measure to deal with the low number of ?TLS slots
+	provided by some of the variants of Windows (60-80).
+
+2003-04-24  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclFileName.c: fix to bug reported privately by Jeff where,
+	for example, 'glob -path {[tcl]} *' gets confused by the leading
+	special character (which is escaped internally), and instead lists
+	files in '/'. Bug only occurs on Windows where '\' is also a directory
+	separator.
+	* tests/fileName.test: added test for the above bug.
+
+2003-04-22  Andreas Kupries  <andreask@activestate.com>
+
+	* The changes below fix SF bugs [593810], and [718045].
+
+	* generic/tclIO.c (Tcl_CutChannel, Tcl_SpliceChannel): Invoke
+	TclpCutSockChannel and TclpSpliceSockChannel.
+
+	* generic/tclInt.h: Declare TclpCutSockChannel and
+	TclpSpliceSockChannel.
+
+	* unix/tclUnixSock.c (TclpCutSockChannel, TclpSpliceSockChannel):
+	Dummy functions, on unix the sockets are _not_ handled specially.
+
+	* mac/tclMacSock.c (TclpCutSockChannel, TclpSpliceSockChannel):
+	* win/tclWinSock.c (TclpCutSockChannel, TclpSpliceSockChannel): New
+	functions to handle socket specific cut/splice operations: auto-init
+	of socket system for thread on splice, management of the module
+	internal per-thread list of sockets, management of association of
+	sockets with HWNDs for event notification.
+
+	* win/tclWinSock.c (NewSocketInfo): Extended initialization
+	assignments to cover all items of the structure. During debugging of
+	the new code mentioned above I found that two fileds could contain
+	bogus data.
+
+	* win/tclWinFile.c: Added #undef HAVE_NO_FINDEX_ENUMS before
+	definition because when compiling in debug mode the compiler complains
+	about a redefinition, and this warning is also treated as an error.
+
+2003-04-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl:  When the return code of a test does
+	not meet expectations, report that as the reason for test failure, and
+	do not attempt to check the test result for correctness. [Bug 725253]
+
+2003-04-18  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/tclWinInt.h (VER_PLATFORM_WIN32_CE): conditionally define.
+	* win/tclWinInit.c: recognize Windows CE as a Win platform. This just
+	recognizes CE - full support will come later.
+
+	* win/configure: regen
+	* win/configure.in (SHELL): force it to /bin/sh as autoconf 2.5x
+	uses /bin/bash, which can fail to find exes in the path (ie: lib).
+
+	* generic/tclExecute.c (ExprCallMathFunc): remove incorrect
+	extraneous cast from Tcl_WideAsDouble.
+
+2003-04-18  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/open.n:		Moved serial port options from [fconfigure] to
+	* doc/fconfigure.n:	[open] as it is up to the creator of a channel

+				options. [Bug 679010]

+2003-04-16  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tcl.h:	Made changes so that the "wideInt" Tcl_ObjType
+	* generic/tclObj.c:	is defined on all platforms, even those where
+	* generic/tclPort.h:	TCL_WIDE_INT_IS_LONG is defined. Also made the
+	Tcl_Value struct have a wideValue field on all platforms. This is a
+	***POTENTIAL INCOMPATIBILITY*** for TCL_WIDE_INT_IS_LONG platforms
+	because that struct changes size. This is the same TIP 72
+	incompatibility that was seen on other platforms at the 8.4.0 release,
+	when this change should have happened as well. [Bug 713562]
+
+	* generic/tclInt.h:  New internal macros TclGetWide() and
+	TclGetLongFromWide() to deal with both forms of the "wideInt"
+	Tcl_ObjType, so that conditional TCL_WIDE_INT_IS_LONG code is confined
+	to the header file.
+
+	* generic/tclCmdAH.c:	Replaced most coding that was conditional
+	* generic/tclCmdIL.c:	on TCL_WIDE_INT_IS_LONG with code that
+	* generic/tclExecute.c: works across platforms, sometimes using
+	* generic/tclTest.c:	the new macros above to do it.
+	* generic/tclUtil.c:
+	* generic/tclVar.c:
+
+2003-04-17  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/socket.n: Added a paragraph to remind people to specify their
+	encodings when using sockets. [Bug 630621]
+
+2003-04-16  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/CrtMathFnc.3: Functions also have to deal with wide ints, but
+	this was not documented. [Bug 709720]
+
+2003-04-16  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclPathObj.c: removed undesired 'static' for function which
+	is now shared (previously it was duplicated).
+
+2003-04-15  Joe English  <jenglish@users.sourceforge.net>
+
+	* doc/namespace.n: added example section "SCOPED SCRIPTS", supplied by
+	Kevin Kenny. [Bug 219183]
+
+2003-04-15  Kevin Kenny  <kennykb@acm.org>
+
+	* makefile.vc: Updated makefile.vc to conform with Mo DeJong's changes
+	to Makefile.in and tclWinPipe.c on 2003-04-14. Now passes TCL_PIPE_DLL
+	in place of TCL_DBGX.
+	* win/tclWinTime.c: Corrected use of types to make compilation
+	compatible with VC++5.
+
+2003-04-15  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c: finished check-in from yesterday, removing
+	duplicate function definition.
+
+2003-04-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclClock.c:	Corrected compiler warnings.
+	* generic/tclTest.c:
+
+2003-04-14  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/Makefile.in: Don't define TCL_DBGX symbol for every compile.
+	Instead, define TCL_PIPE_DLL only when compiling tclWinPipe.c. This
+	will break other build systems, so they will need to remove the
+	TCL_DBGX define and replace it with a define for TCL_PIPE_DLL.
+	* win/tclWinPipe.c (TclpCreateProcess): Remove PREFIX_IDENT and
+	DEBUG_IDENT from top of file. Use TCL_PIPE_DLL passed in from build
+	env instead of trying to construct the dll name from already defined
+	symbols. This approach is more flexible and better in the long run.
+
+2003-04-14  Kevin Kenny  <kennykb@acm.org>
+
+	* win/tclWinFile.c: added conditionals to restore compilation on
+	VC++6, which was broken by recent changes.
+
+2003-04-14  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c:
+	* generic/tclPathObj.c:
+	* generic/tclFileSystem.h: overlooked one function which was
+	duplicated, so this is now shared between modules.
+	* win/tclWinFile.c: allow this file to compile with VC++ 5.2 again
+	since Mingw build fixes broke that.
+
+2003-04-13  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure: Regen.
+	* win/configure.in: Add check for FINDEX_INFO_LEVELS from winbase.h,
+	known to be a problem in VC++ 5.2. Define HAVE_NO_FINDEX_ENUMS if the
+	define does not exist.
+	* win/tclWinFile.c: Put declarations for FINDEX_INFO_LEVELS and
+	FINDEX_SEARCH_OPS inside a check for HAVE_NO_FINDEX_ENUMS so that
+	these are not declared twice. This fixes the Mingw build.
+	* win/tclWinTime.c: Rework the init of timeInfo so that the number or
+	initializers matches the declaration. This was broken under Mingw. Add
+	cast to avoid compile warning when calling the AccumulateSample
+	function.
+
+2003-04-12  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/Makefile.in (GENERIC_OBJS): add missing tclPathObj.c
+
+2003-04-12  Kevin Kenny  <kennykb@acm.org>
+
+	* doc/clock.n:
+	* generic/tclClock.c (Tcl_ClockObjCmd):
+	* tests/clock.test: Implementation of TIP #124. Also renumbered test
+	cases to avoid duplicates. [Bug 710310]

+	* win/tclWinTest.c (TestwinclockCmd, TestwinsleepCmd):
+	* win/tclWinTime.c (Tcl_WinTime, UpdateTimeEachSecond,
+	(ResetCounterSamples, AccumulateSample, SAMPLES, TimeInfo): Made
+	substantial changes to the phase-locked loop (replaced an IIR filter
+	with an FIR one) in a quest for improved loop stability (Bug not
+	logged at SF, but cited in private communication from Jeff Hobbs).
+
+2003-04-11  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd,STR_IS_INT):  Corrected
+	inconsistent results of [string is integer] observed on systems where
+	sizeof(long) != sizeof(int). [Bug 718878]
+	* tests/string.test: Added tests for Bug 718878.
+	* doc/string.n: Clarified that [string is integer] accepts 32-bit
+	integers.
+
+2003-04-11  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (UpdateInterest): When dropping interest in
+	TCL_READABLE now dropping interest in TCL_EXCEPTION too. This fixes a
+	bug where Expect detects eof on a file prematurely on solaris 2.6 and
+	higher. A much more complete explanation is in the code itself (40
+	lines of comments for a one-line change :)
+
+2003-04-11  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* tests/cmdAH.test: fix test suite problem if /home is a symlink. [Bug
+	703264]
+	* generic/tclIOUtil.c: fix bad error message with 'cd ""'. [Bug
+	704917]
+	* win/tclWinFile.c, win/tclWin32Dll.c:
+	* win/tclWinInt.h: allow Tcl to differentiate between reparse points
+	which are symlinks and mounted volumes, and correctly handle the
+	latter. This involves some elaborate code to find the actual drive
+	letter (if possible) corresponding to a mounted volume. [Bug 697862]
+	* tests/fileSystem.test: add constraints to stop tests running in
+	ordinary tcl interpreter. [Bug 705675]
+
+	* generic/tclIOUtil.c:
+	* generic/tclPathObj.c: (new file)
+	* generic/tclFileSystem.h: (new file)
+	* win/makefile.vc:
+	Split path object handling out of the virtual filesystem layer, into
+	tclPathObj.c. This refactoring cleans up the internal filesystem code,
+	and will make any future optimisations and forthcoming better
+	thread-safety much easier.
+
+	* generic/tclTest.c:
+	* tests/reg.test: added some 'knownBug' tests for problems in Tcl's
+	regexp code with the TCL_REG_CAN_MATCH flag (see Bug 703709). Code too
+	impenetrable to fix right now, but a fix is needed for tip113 to work
+	correctly.
+
+	* tests/fCmd.test
+	* win/tclWinFile.c: added some filesystem optimisation to the 'glob'
+	implementation, and some new tests.
+
+	* generic/tclCmdMZ.c: fix typo in comment
+
+	* tests/winFile.test:
+	* tests/ioUtil.test:
+	* tests/unixFCmd.test: renumbered tests with duplicate numbers. [Bug

+
+2003-04-10  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

+
+2003-04-08  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclCmdAH.c (Tcl_ErrorObjCmd): Strings are only empty if
+	they have zero length, not if their first byte is zero, so fix test
+	guarding Tcl_AddObjErrorInfo to take this into account. [Bug
+	reported by Don Porter; no bug-id.]
+
+2003-04-07  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclCompCmds.c (TclCompileIfCmd):  Corrected string limits of

+
+	* generic/tclCmdMZ.c (TraceExecutionProc):  Added missing
+	Tcl_DiscardResult() call to avoid memory leak.
+
+2003-04-07  Donal K. Fellows  <zzcgudf@ernie.mvc.mcc.ac.uk>
+
+	* generic/tclDictObj.c (Tcl_DictObjCmd): Stopped compilers from

+	Miguel Sofer by private chat.
+
+2003-04-07  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

+	Failed to fully initialise the Dict structure.
+	(DictIncrCmd): Moved valueAlreadyInDictionary label to stop compiler
+	complaints. [Bug 715751]
+
+	* generic/tclDictObj.c (DictIncrCmd): Followed style in the rest of
+	the core by commenting out wide-specific operations on platforms where
+	wides are longs, and used longs more thoroughly than ints through
+	[dict incr] anyway to forestall further bugs.
+	* generic/tclObj.c: Made sure there's always a tclWideIntType
+	implementation available, not that it is always useful. [Bug 713562]
+
+2003-04-05  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclDictObj.c: Removed commented out notes on declarations to

+	configure script.
+
+2003-04-03  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/Makefile.in: Don't subst MATH_LIBS, LIBS, and DL_LIBS
+	separately. Instead, just subst TCL_LIBS since it includes the
+	others.
+	* unix/configure: Regen.
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS, SC_TCL_LINK_LIBS): Set and subst
+	TCL_LIBS in SC_CONFIG_CFLAGS instead of SC_TCL_LINK_LIBS. Don't subst
+	MATH_LIBS since it is now covered by TCL_LIBS.
+	* unix/tclConfig.sh.in: Use TCL_LIBS instead of DL_LIBS, LIBS, and

+2003-04-02  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure: Regen.
+	* win/configure.in: Set stub lib flag based on new LIBFLAGSUFFIX
+	variable.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Set new LIBFLAGSUFFIX that works like
+	LIBSUFFIX, it is used when creating library names. The previous
+	implementation would generate -ltclstub85 instead of -ltclstub85s when
+	configured with --disable-shared.
+
+2003-04-02  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclParse.c (TclSubstTokens):  Moved declaration of

+
+2003-04-01  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/README:  Direct [source] of *.test files is no longer

+	control of the [runAllTests] command in tests/all.tcl.
+
+	* generic/tclExecute.c (INST_RETURN):  Bytecompiled [return] failed to
+	reset iPtr->returnCode, causing tests parse-18.17 and parse-18.21 to

+2003-03-31  Don Porter  <dgp@users.sourceforge.net>
+

+
+2003-03-27  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/configure: Regen.

+	or [package require registry] attempted to load the release version
+	of the DLL into a debug build. [Bug 708218] Thanks to Joe Mistachkin
+	for the patch.
+	* win/makefile.vc: Added quoting around the script name in the 'test'

+	* generic/tclParse.c (ParseTokens,Tcl_SubstObj,TclSubstTokens):
+	* tests/subst.test (2.4, 8.7, 8.8, 11.4, 11.5):
+	Substantial refactoring of Tcl_SubstObj to make use of the same
+	parsing and substitution procedures as normal script evaluation.
+	Tcl_SubstObj() moved to tclParse.c. New routine TclSubstTokens()
+	created in tclParse.c which implements all substantial functioning of
+	Tcl_EvalTokensStandard(). TclCompileScript() loses its "nested"
+	argument, the Tcl_Interp struct loses its termOffset field and the
+	TCL_BRACKET_TERM flag in the evalFlags field, all of which were only
+	used (indirectly) by Tcl_SubstObj(). Tests subst-8.7,8.8,11.4,11.5
+	modified to accomodate the only behavior change: reporting of parse
+	errors now takes precedence over [return] and [continue] exceptions.
+	All other behavior should remain compatible. [RFE 536831,684982] [Bug
+	685106]
+
+	* generic/tcl.h:        Removed TCL_PREFIX_IDENT and TCL_DEBUG_IDENT
+	* win/tclWinPipe.c:     from tcl.h -- they are not part of Tcl's
+	public interface.  Put them in win/tclWinPipe.c where they are used.
+
+	* generic/tclInterp.c (Tcl_InterpObjCmd):       Corrected and added
+	* tests/interp.test (interp-2.13):              test for option
+	parsing beyond objc for [interp create --]. Thanks to Marco Maggi.
+	[Bug 702383]
+
+2003-03-11  Kevin Kenny  <kennykb@users.sourceforge.net>
+
+	* win/makefile.vc: Added two missing uses of $(DBGX) so that
+	tclpip8x.dll loads without panicking on Win9x.
+
+2003-03-09  Kevin Kenny  <kennykb@users.sourceforge.net>
+
+	* generic/tclTest.c (TestChannelCmd): Removed an unused local variable
+	that caused compilation problems on some platforms.
+
+2003-03-08  Don Porter  <dgp@users.sourceforge.net>
+
+	* doc/tcltest.n:  Added missing "-body" to example. Thanks to Helmut
+	Giese. [Bug 700011]
+
+2003-03-07  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* tests/io.test:
+	* tests/ioCmd.test: Define a fcopy constraint and add it to the
+	constraint list of any test that depends on the fcopy command. This is
+	only useful to Jacl which does not support fcopy.
+
+2003-03-07  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* tests/encoding.test: Name temp files *.tcltestout instead of *.out
+	so that when they are removed later, we don't accidently toast any
+	files named *.out that the user has created in the build directory.
+
+2003-03-07  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclCmdAH.c (Tcl_FileObjCmd): Fix the setting of a file's
+	mtime and atime on 64-bit platforms. [Bug 698146]
+
+2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>
+

+	tests.
+
+2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* tests/io.test: Define a fileevent constraint and add it to the
+	constraint list of any test that depends on the fileevent command.
+	This is only useful to Jacl which does not support fileevent.
+
+2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* tests/io.test: Define an openpipe constraint and add it to the
+	constraint list of any test that creates a pipe using the open
+	command. This is only useful to Jacl which does not support pipes.
+
+2003-03-06  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/TclUtf.c (Tcl_UniCharNcasecmp):       Corrected failure to
+	* tests/utf.test (utf-25.*):    properly compare Unicode strings of
+	different case in a case insensitive manner.  [Bug 699042]
+
+2003-03-06  Kevin Kenny  <kennykb@users.sourceforge.net>
+
+	* generic/tclCompCmds.c (TclCompileSwitchCmd):
+	Replaced a non-portable 'bzero' with a portable 'memset'. [Bug 698442]
+
+2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclIO.c (Tcl_Seek, Tcl_OutputBuffered): If there is data
+	buffered in the statePtr->curOutPtr member then set the BUFFER_READY
+	flag in Tcl_Seek. This is needed so that the next call to FlushChannel
+	will write any buffered bytes before doing the seek. The existing code
+	would set the BUFFER_READY flag inside the Tcl_OutputBuffered
+	function. This was a programming error made when Tcl_OutputBuffered
+	was originally created in CVS revision 1.35. The setting of the
+	BUFFER_READY flag should not have been included in the
+	Tcl_OutputBuffered function.
+	* generic/tclTest.c (TestChannelCmd): Use the Tcl_InputBuffered and
+	Tcl_OutputBuffered util methods to query the amount of buffered input
+	and output.
+
+2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclIO.c (Tcl_Flush): Compare the nextAdded member of the
+	ChannelBuffer to the nextRemoved member to determine if any output has
+	been buffered. The previous check against the value 0 seems to have
+	just been a coding error. See other methods like Tcl_OutputBuffered
+	for examples where nextAdded is compared to nextRemoved to find the
+	number of bytes buffered.
+
+2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclIO.c (Tcl_GetsObj): Check that the eol pointer has not
+	gone past the end of the string when in auto translation mode and the
+	INPUT_SAW_CR flag is set. The previous code worked because the end of
+	string value \0 was being compared to \n, this patch just skips that
+	pointless check.
+
+2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclIO.c (WriteBytes, WriteChars, Tcl_GetsObj, ReadBytes):
+	Rework calls to TranslateOutputEOL to make it clear that a boolean
+	value is being returned. Add some comments in an effort to make the
+	code more clear. This patch makes no functional changes.
+
+2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclIO.c (Tcl_SetChannelOption): Invoke the
+	Tcl_SetChannelBufferSize method as a result of changing the
+	-buffersize option to fconfigure. The previous implementation used
+	some inlined code that reset the buffer size to the default size
+	instead of ignoring the request as implemented in
+	Tcl_SetChannelBufferSize.
+	* tests/io.test: Update test case so that it actually checks the
+	implementation of Tcl_SetChannelBufferSize.
+
+2003-03-05  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/rules.vc: updated default tcl version to 8.5.
+
+2003-03-05  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* generic/tclCompCmds.c (TclCompileSwitchCmd): First attempt at a
+	bytecode-compiled switch command. It only handles the most common case
+	of switching, but that should be enough for this to speed up a lot of
+	people's code. It is expected that the speed gains come from two
+	things: better handling of the switch itself, and integrated
+	compilation of the arms instead of embedding separate bytecode
+	sequences (i.e. better local variable handling.)
+	* tests/switch.test (switch-10.*): Tests of both uncompiled and
+	compiled switch behaviour. [Patch #644819]
+
+	* generic/tclCompile.h (TclFixupForwardJumpToHere): Additional macro
+	to make the most common kind of jump fixup a bit easier.

+
+2003-02-28  Vince Darley  <vincentdarley@users.sourceforge.net>

+
+2003-02-27  Jeff Hobbs  <jeffh@ActiveState.com>
+

+
+2003-02-27  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* tests/lsearch.test (lsearch-10.7):

+
+2003-02-26  Chengye Mao <chengye.geo@yahoo.com>
+
+	* win/tclWinInit.c: fixed a bug in TclpSetVariables by initializing
+	dwUserNameLen with the sizeof(szUserName) before calling GetUserName.

+
+2003-02-21  Daniel Steffen  <das@users.sourceforge.net>
+
+	* mac/tclMacChan.c (TclpCutFileChannel, TclpSpliceFileChannel):
+	Implemented missing cut and splice procs for file channels.
+
+2003-02-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/package.tcl (tclPkgUnknown):  Minor performance tweaks to

+	times, at least a little bit. [Patch 687906]
+
+2003-02-20  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tcl.m4:
+	* unix/tclUnixPipe.c: (macosx) use vfork() instead of fork() to create

+2003-02-20  Jeff Hobbs  <jeffh@ActiveState.com>
+

+
+2003-02-19  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclStringObj.c: restored Tcl_SetObjLength() side-effect of
+	always invalidating unicode rep (if the obj has a string rep). Added
+	hasUnicode flag to String struct, allows decoupling of validity of
+	unicode rep from buffer size allocated to it (improves memory
+	allocation efficiency). [Bugs 686782, 671138, 635200]
+
+	* macosx/Tcl.pbproj/project.pbxproj:
+	* macosx/Makefile: reworked embedded build to no longer require
+	relinking but to use install_name_tool instead to change the
+	install_names for embedded frameworks. [Bug 644510]
+
+	* macosx/Tcl.pbproj/project.pbxproj: preserve mod dates when running
+	'make install' to build framework (avoids bogus rebuilds of dependent
+	frameworks because tcl headers appear changed).
+
+	* tests/ioCmd.test (iocmd-1.8): fix failure when system encoding is
+	utf-8: use iso8859-1 encoding explicitly.
+
+2003-02-18  Miguel Sofer <msofer@users.sf.net>

+
+2003-02-18  Andreas Kupries  <andreask@activestate.com>
+
+	* unix/tcl.m4: [Bug #651811] Added definition of _XOPEN_SOURCE and
+	linkage of 'xnet' library to HP 11 branch. This kills a lot of
+	socket-related failures in the testsuite when Tcl was compiled in 64
+	bit mode (both PA-RISC 2.0W, and IA 64).
+
+	* unix/configure: Regenerated.

+
+2003-02-18  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclTest.c: cleanup of new 'simplefs' test code, and better
+	documentation.
+
+2003-02-17  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclBasic.c (TclRenameCommand): fixing error in previous

+	* generic/tclCmdMZ.c (Tcl_StringObjCmd STR_MATCH):
+	* generic/tclUtf.c (TclUniCharMatch):
+	* generic/tclInt.decls:  add private TclUniCharMatch function that
+	* generic/tclIntDecls.h: does string match on counted unicode
+	* generic/tclStubInit.c: strings. Tcl_UniCharCaseMatch has the failing
+	* tests/string.test:     that it can't handle strings or patterns with
+	* tests/stringComp.test: embedded NULLs. Added tests that actually try

+	public in the next minor version rev.
+
+2003-02-17  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclBasic.c (TclRenameCommand): 'oldFullName' object was not

+
+2003-02-17  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclIO.c (Tcl_GetsObj): Minor change so that eol is only

+	Q274323 for the hardware problem that makes this necessary on certain
+	machines.
+	* tests/winTime.test: Revised winTime-2.1 - it had a tolerance of

+
+2003-02-11  Jeff Hobbs  <jeffh@ActiveState.com>

+
+	* tests/stringObj.test:
+	* generic/tclStringObj.c (Tcl_GetCharLength): correct ascii char opt
+	of 2002-11-11 to not stop early on \x00. [Bug 684699]
+
+	* tests.parse.test: remove excess EOF whitespace
+
+	* generic/tclParse.c (CommandComplete): more paranoid check to break

+	(Tcl_FSConvertToPathType, Tcl_FSGetNormalizedPath):
+	(Tcl_FSGetFileSystemForPath): Update string rep of path objects before
+	freeing the internal object. (darley)
+
+	* tests/fileSystem.test: added test 8.3
+	* generic/tclIOUtil.c (Tcl_FSGetNormalizedPath):
+	(UpdateStringOfFsPath): handle the cwdLen == 0 case
+

+	match check.
+
+2003-02-10  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure:
+	* win/configure.in: Generate error when attempting to build under
+	Cygwin. The Cygwin port of Tcl/Tk does not build and people are filing
+	bug reports under the mistaken impression that someone is actually
+	maintaining the Cygwin port. A post to comp.lang.tcl asking someone to
+	volunteer as an area maintainer has generated no results. Closing bugs
+	680840, 630199, and 634772 and marking as "Won't fix".
+
+2003-02-10  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

+	* generic/tclInt.h:
+	* tests/fileSystem.test:
+	* unix/tclUnixFCmd.c:
+	* unix/tclUnixFile.c:
+	* win/tclWinFile.c: further filesystem optimization, applying [Patch
+	682500]. In particular, these code examples are faster now:
+	    foreach f $flist { if {[file exists $f]} {file stat $f arr;...}}
+	    foreach f [glob -dir $dir *] { # action and/or recursion on $f }
+	    cd $dir
+	    foreach f [glob *] { # action and/or recursion on $f }
+	    cd ..
+
+	* generic/tclTest.c: Fix for [Bug 683181] where test suite left files
+	in 'tmp'.
+
+2003-02-08  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* library/safe.tcl: code cleanup of eval and string comp use.
+
+2003-02-07  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* win/tclWinFCmd.c: cleanup long lines
+	* win/tclWinFile.c: sped up pure 'glob' by a factor of 2.5
+	('foreach f [glob *] { file exists $f }' is still slow)
+	* tests/fileSystem.text:
+	* tests/fileName.test: added new tests to ensure correct behaviour in
+	optimized filesystem code.
+
+2003-02-07  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclTest.c:
+	* tests/fileSystem.text: fixed test 7.2 to avoid a possible crash, and
+	not change the pwd.
+
+	* tests/http.text: added comment to test 4.15, that it may fail if you
+	use a proxy server.
+
+2003-02-06  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclCompCmds.c (TclCompileIncrCmd):
+	* tests/incr.test: Don't include the text "(increment expression)" in
+	the errorInfo generated by the compiled version of the incr command
+	since it does not match the message generated by the non-compiled
+	version of incr. It is also not possible to match this error output
+	under Jacl, which does not support a compiler.
+
+2003-02-06  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclExecute.c (TclExecuteByteCode): When an error is
+	encountered reading the increment value during a compiled call to
+	incr, add a "(reading increment)" error string to the errorInfo
+	variable. This makes the errorInfo variable set by the compiled incr
+	command match the value set by the non-compiled version.
+	* tests/incr-old.test: Change errorInfo result for the compiled incr
+	command case to match the modified implementation.
+	* tests/incr.test: Add tests to make sure the compiled and
+	non-compiled errorInfo messages are the same.
+
+2003-02-06  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl:  Filename arguments to [outputChannel]
+	and [errorChannel] (also -outfile and -errfile) were [open]ed but
+	never [closed]. Also, [cleanupTests] could remove output or error
+	files. [Bug 676978].
+	* library/tcltest/pkgIndex.tcl: Bumped to version 2.2.2.
+
+2003-02-05  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* tests/interp.test:
+	* tests/set-old.test: Run test cases that depend on hash order through
+	lsort so that the tests also pass under Jacl. Does not change test
+	results under Tcl.
+

+	* mac/tclMacFCmd.c:
+	* unix/tclUnixFCmd.c:
+	* win/tclWin32Dll.c:
+	* win/tclWinFCmd.c:
+	* win/tclWinInit.c:
+	* win/tclWinInt.h:
+	* tests/fileSystem.test: fix to finalization/unloading/encoding issues
+	to make filesystem much less dependent on encodings for its cleanup,
+	and therefore allow it to be finalized later in the exit process. This
+	fixes fileSystem.test-7.1. Also fixed one more bug in setting of
+	modification dates of files which have undergone cross-platform
+	copies. [Patch 676271]
+
+	* tests/basic.test:
+	* tests/exec.test:
+	* tests/fileName.test:
+	* tests/io.test: fixed some test failures when tests are run from a
+	directory containing spaces.
+
+	* tests/fileSystem.test:
+	* generic/tclTest.c: added regression test for the modification date
+	setting of cross-platform file copies.
+
+2003-02-03  Kevin Kenny  <kennykb@users.sourceforge.net>
+
+	* generic/tclBasic.c: Changed [trace add command] so that 'rename'
+	callbacks get fully qualified names of the command. [Bug 651271].
+	***POTENTIAL INCOMPATIBILITY***
+	* tests/trace.test: Modified the test cases for [trace add command] to
+	expect fully qualified names on the 'rename' callbacks. Added a case
+	for renaming a proc within a namespace.
+	* doc/trace.n: Added language about use of fully qualified names in
+	trace callbacks.
+
+2003-02-01  Kevin Kenny  <kennykb@users.sourceforge.net>
+
+	* generic/tclCompCmds.c: Removed an unused variable that caused
+	compiler warnings on SGI. [Bug 664379]
+
+	* generic/tclLoad.c: Changed the code so that if Tcl_StaticPackage is
+	called to report the same package as being loaded in two interps, it
+	shows up in [info loaded {}] in both of them (previously, it didn't
+	appear in the static package list in the second).
+
+	* tests/load.test Added regression test for the above bug. [Bug
+	670042]
+
+	* generic/tclClock.c: Fixed a bug that incorrectly allowed [clock
+	clicks {}] and [clock clicks -] to be accepted as if they were [clock
+	clicks -milliseconds].
+
+	* tests/clock.test: Added regression tests for the above bug. [Bug
+	675356]
+
+	* tests/unixNotfy.test: Added cleanup of working files. [Bug 675609]
+
+	* doc/Tcl.n: Added headings to the eleven paragraphs, to improve
+	formatting in the tools that attempt to extract tables of contents
+	from the manual pages. [Bug 627455]
+
+	* generic/tclClock.c: Expanded mutex protection around the setting of
+	env(TZ) and the thread-unsafe call to tzset(). [Bug 656660]
+
+2003-01-31  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/tcltest.test: Cleaned up management of file/directory
+	creation/deletion to improve "-debug 1" output. [Bug 675614]
+	The utility [slave] command failed to properly [list]-quote a
+	constructed [open] command, causing failure when the pathname
+	contained whitespace. [Bug 678415]
+
+	* tests/main.test: Stopped main.test from deleting existing file. Test
+	suite should not delete files that already exist. [Bug 675660]
+
+2003-01-28  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/main.test: Constrain tests that do not work on Windows. [Bug
+	674387]
+
+2003-01-28  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c: fix to setting modification date in
+	TclCrossFilesystemCopy. Also added 'panic' in
+	Tcl_FSGetFileSystemForPath under illegal calling circumstances which
+	lead to hard-to-track-down bugs.
+
+	* generic/tclTest.c: added test suite code to allow exercising a
+	vfs-crash-on-exit bug in Tcl's finalization caused by the encodings
+	being cleaned up before unloading occurs.
+	* tests/fileSystem.test: added new 'knownBug' test 7.1 to demonstrate
+	the crash on exit.
+
+2003-01-28  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tcl.h: Add TCL_PREFIX_IDENT and TCL_DEBUG_IDENT, used only
+	by TclpCreateProcess.
+	* unix/Makefile.in: Define TCL_DBGX.
+	* win/Makefile.in: Define TCL_DBGX.
+	* win/tclWinPipe.c (TclpCreateProcess): Check that the Tcl pipe dll
+	actually exists in the Tcl bin directory and panic if it is not found.
+	Incorporate TCL_DBGX into the Tcl pipe dll name. This fixes a really
+	mysterious error that would show up when exec'ing a 16 bit application
+	under Win95 or Win98 when Tcl was compiled with symbols. The error
+	seemed to indicate that the executable could not be found, but it was
+	actually the Tcl pipe dll that could not be found.
+
+2003-01-26  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/README: Update msys+mingw URL to release 6. This version bundles
+	gcc 3.
+
+2003-01-26  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure: Regen.
+	* win/configure.in: Add test that checks to see if the compiler can
+	cast to a union type.
+	* win/tclWinTime.c: Squelch compiler warning about union initializer
+	by casting to union type when compiling with gcc.
+
+2003-01-25  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclIO.c (Tcl_CutChannel, Tcl_SpliceChannel): Invoke
+	TclpCutFileChannel and TclpSpliceFileChannel.
+	* generic/tclInt.h: Declare TclpCutFileChannel and
+	TclpSpliceFileChannel.
+	* unix/tclUnixChan.c (FileCloseProc, TclpOpenFileChannel,
+	(Tcl_MakeFileChannel, TclpCutFileChannel, TclpSpliceFileChannel):
+	Implement thread load data cut and splice for file channels. This
+	avoids an invalid memory ref when compiled with -DDEPRECATED.
+	* win/tclWinChan.c (FileCloseProc, TclpCutFileChannel,
+	(TclpSpliceFileChannel): Implement thread load data cut and splice for
+	file channels. This avoids an invalid memory ref that was showing up
+	in the thread extension.
+
+2003-01-25  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/tclWin32Dll.c (TclpCheckStackSpace, squelch_warnings):
+	* win/tclWinChan.c (Tcl_MakeFileChannel, squelch_warnings):
+	* win/tclWinFCmd.c (DoRenameFile, DoCopyFile, squelch_warnings):
+	Re-implement inline ASM SEH handlers for gcc. The esp and ebp
+	registers are now saved on the stack instead of in global variables so
+	that the code is thread safe. Add additional checks when TCL_MEM_DEBUG
+	is defined to be sure the values were recovered from the stack
+	properly. Remove squelch_warnings functions and add a dummy call in
+	the handler methods to squelch compiler warnings.
+
+2003-01-25  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure:
+	* win/configure.in: Define HAVE_ALLOCA_GCC_INLINE when we detect that
+	no alloca function is found in malloc.h and we are compiling with GCC.
+	Remove HAVE_NO_ALLOC_DECL define.
+	* win/tclWin32Dll.c (TclpCheckStackSpace): Don't define alloca as a
+	cdecl function. Doing this caused a tricky runtime bug because the
+	_alloca function expects the size argument to be passed in a register
+	and not on the stack. To fix this problem, we use inline ASM when
+	compiling with gcc to invoke _alloca with the size argument loaded
+	into a register.
+
+2003-01-24  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/tclWinDde.c (Dde_Init): clarified use of tsdPtr.
+	(DdeServerProc): better refcount handling of returnPackagePtr.
+
+	* generic/tclEvent.c (Tcl_Finalize): revert finalize change on
+	2002-12-04 to correct the issue with extensions that have TSD needing
+	to finalize that before they are unloaded. This issue needs further
+	clarification.
+
+	* tests/unixFCmd.test: only do groups check on unix
+
+2003-01-24  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclStringObj.c: proper fixes for Tcl_SetObjLength and
+	Tcl_AttemptSetObjectLength dealing with string objects with both
+	pure-unicode and normal internal representations. Previous fix didn't
+	handle all cases correctly.
+	* generic/tclIO.c: Add 'Tcl_GetString()' to ensure the object has a
+	valid 'objPtr->bytes' field before manipulating it directly.
+
+	This fixes [Bug 635200] and [Bug 671138], but may reduce performance
+	of Unicode string handling in some cases. A further patch will be
+	applied to address this, once the code is known to be correct.
+
+2003-01-24  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure: Regen.
+	* win/configure.in: Add test to see if alloca is undefined in
+	malloc.h.
+	* win/tclWin32Dll.c (TclpCheckStackSpace): Rework the SEH exception
+	handler logic to avoid using the stack since alloca will modify the
+	stack. This was causing a nasty bug that would set the exception
+	handler to 0 because it tried to pop the previous exception handler
+	off the top of the stack.
+
+2003-01-23  Donal K. Fellows  <fellowsd@cs.man.ac.uk>
+
+	* doc/lset.n: Fixed fault in return values from lset in documentation
+	examples [SF Bug #658463] and tidied up a bit at the same time.
+
+2003-01-21  Joe English  <jenglish@users.sourceforge.net>
+
+	* doc/namespace.n (namespace inscope): Clarified documentation
+	[Patch 670110]
+
+2003-01-21  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure: Regen.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Set SHLIB_SUFFIX so that
+	TCL_SHLIB_SUFFIX will be set to a useful value in the generated
+	tclConfig.sh. Set SHLIB_LD_LIBS to "" or '${LIBS}' based on the
+	--enable-shared flag. This matches the UNIX implementation.
+
+2003-01-18  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclCkalloc.c: change %ud to %u as appropriate.
+
+2003-01-17  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/tclWinDde.c (DdeServerProc): Deallocate the Tcl_Obj returned by
+	ExecuteRemoteObject if it was not saved in a connection object.
+
+2003-01-17  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tcl.h: Revert earlier change that defined TCL_WIDE_INT_TYPE
+	as long long and TCL_LL_MODIFIER as L when compiling with mingw. This
+	change ended up causing some test case failures when compiling with
+	mingw.
+	* generic/tclObj.c (UpdateStringOfWideInt): Describe the warning
+	generated by mingw and why it needs to be ignored so that someone is
+	not tempted to "fix" this problem again in the future.
+
+2003-01-16  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclStringObj.c: Tcl_SetObjLength fix for when the object has
+	a unicode string rep. [Bug 635200]
+	* tests/stringObj.test: removed 'knownBug' constraint from test 14.1
+	now that this bug is fixed.
+
+	* generic/tclInt.h:
+	* generic/tclBasic.c:
+	* generic/tclCmdMZ.z:
+	* tests/trace.test: execution and command tracing bug fixes and
+	cleanup. In particular fixed [Bug 655645], [Bug 615043], [Bug 571385]
+	  - fixed some subtle cleanup problems with tracing. This required
+	    replacing Tcl_Preserve/Tcl_Release with a more robust refCount
+	    approach. Solves at least one known crash caused by memory
+	    corruption.
+	  - fixed some confusion in the code between new style traces (Tcl
+	    8.4) and the very limited 'Tcl_CreateTrace' which existed before.
+	  - made behaviour consistent with documentation (several tests even
+	    contradicted the documentation before).
+	  - fixed some minor error message details
+	  - added a number of new tests
+
+2003-01-16  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/tclWinSerial.c (SerialOutputProc): add casts for bytesWritten to
+	allow strict compilation (no warnings).
+
+	* tests/winDde.test:
+	* win/tclWinDde.c (Tcl_DdeObjCmd): Prevent crash when empty service
+	name is passed to 'dde eval' and goto errorNoResult in request and
+	poke error cases to free up any allocated data.
+
+2003-01-16  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/tclWin32Dll.c (squelch_warnings): Squelch compiler warnings from
+	SEH ASM code.
+	* win/tclWinChan.c (squelch_warnings): Squelch compiler warnings from
+	SEH ASM code.
+	* win/tclWinDde.c: Add casts to avoid compiler warnings. Pass pointer
+	to DWORD instead of int to avoid compiler warnings.
+	* win/tclWinFCmd.c (squelch_warnings): Add casts and fixup decls to
+	avoid compiler warnings. Squelch compiler warnings from SEH ASM code.
+	* win/tclWinFile.c: Add casts and fixup decls to avoid compiler
+	warnings. Remove unused variable.
+	* win/tclWinNotify.c: Declare as DWORD instead of int to avoid
+	compiler warning.
+	* win/tclWinReg.c: Add casts to avoid compiler warning. Fix assignment
+	in if expression bug.
+	* win/tclWinSerial.c: Add casts to avoid compiler warnings. Remove
+	unused variable.
+	* win/tclWinSock.c: Add casts and fixup decls to avoid compiler
+	warnings.
+
+2003-01-14  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclClock.c (FormatClock): corrected typo that incorrectly
+	conditionally defined savedTZEnv and savedTimeZone.
+
+2003-01-13  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	Fix mingw build problems and compiler warnings.
+
+	* generic/tcl.h: Add if defined(__MINGW32__) check to code that sets
+	the TCL_WIDE_INT_TYPE and TCL_LL_MODIFIER.
+	* generic/tclClock.c (FormatClock): Don't define savedTimeZone and
+	savedTZEnv if we are not going to use them.
+	* generic/tclEnv.c: Add cast to avoid warning.
+	* win/tclWinChan.c: Use DWORD instead of int to avoid compiler warning
+	* win/tclWinThrd.c: Only define allocLock, allocLockPtr, and dataKey
+	when TCL_THREADS is defined. This avoid a compiler warning about
+	unused variables.
+
+2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/README: Update msys + mingw URL, the new release includes the
+	released 1.0.8 version of msys which includes a number of bug fixes.
+
+2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure: Regen.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Pull in addition of shell32.lib to
+	LIBS_GUI that was added to the Tk tcl.m4 but never made it back into
+	the Tcl version.
+
+2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tcl.h: Skip Tcl's define of CHAR, SHORT, and LONG when
+	HAVE_WINNT_IGNORE_VOID is defined. This avoids a bunch of compiler
+	warnings when building with Cygwin or Mingw.
+	* win/configure: Regen.
+	* win/configure.in: Define HAVE_WINNT_IGNORE_VOID when we detect a
+	winnt.h that still defines CHAR, SHORT, and LONG when VOID has already
+	been defined.
+	* win/tcl.m4 (SC_LOAD_TCLCONFIG): Subst the TCL_DEFS loaded from
+	tclConfig.sh so that Tcl defines can make it into the Tk Makefile.
+
+2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure: Regen.
+	* win/configure.in: Check for typedefs like LPFN_ACCEPT in winsock2.h
+	and define HAVE_NO_LPFN_DECLS if not found.
+	* win/tclWinSock.c: Define LPFN_* typedefs if HAVE_NO_LPFN_DECLS is
+	defined. This fixes the build under Mingw and Cygwin, it was broken by
+	the changes made on 2002-11-26.
+
+2003-01-10  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c:
+	* win/tclWinInt.h:
+	* win/tclWinInit.c: fix to new WinTcl crash on exit with vfs,
+	introduced on 2002-12-06. Encodings must be cleaned up after the
+	filesystem.
+
+	* win/makefile.vc: fix to minor VC++ 5.2 syntax problem
+
+2003-01-09  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclCompCmds.c (TclCompileReturnCmd):  Corrected off-by-one
+	problem with recent commit. [Bug 633204]
+
+2003-01-09  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclFileName.c: remove unused variable 'macSpecialCase'
+	[Bug 664749]

+	* generic/tclInt.h:
+	* unix/tclUnixFile.c:
+	* mac/tclMacFile.c:
+	* win/tclWinFile.c:
+	* win/tclWinInt.h:
+	* win/tclWin32Dll.c:
+	* tests/cmdAH.test: fix to non-ascii chars in paths when setting mtime
+	and atime through 'file (a|m)time $path $time'. [Bug 634151]
+
+2003-01-08  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c (TclExprFloatError):  Use the IS_NAN macro for
+	greater clarity of code.
+
+2003-01-07  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclCompCmds.c (TclCompileReturnCmd):
+	* tests/compile.test:	Corrects failure of bytecompiled [catch
+	{return}] to have result TCL_RETURN (not TCL_OK) [Bug 633204]. This
+	patch is a workaround for 8.4.X. A new opcode INST_RETURN is a better
+	long term solution for 8.5 and later.
+
+2003-01-04  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/makefile.vc:
+	* win/rules.vc:  Fixed INSTALLDIR macro problem that blanked itself by
+	accident causing the install target to put the tree at the root of the
+	drive built on. Whoops..
+
+	Renamed the 'linkexten' option to be 'staticpkg'. Added 'thrdalloc' to
+	allow the switching _on_ of the thread allocator. Under testing, I
+	found it not to be benificial under windows for the purpose of the
+	application I was using it for. It was more important for this app
+	that resources for tcl threads be returned to the system rather than
+	saved/moved to the global recycler. Be extra clean or extra fast for
+	the default threaded build? Let's move to clean and allow it to be
+	switched on for users who find it benificial for their use of threads.

+	(included in -O2) and -GD (outdated). Use "link -lib" instead of "lib"
+	binary and remove -YX for MSVC7 portability. Add -fomit-frame-pointer
+	for gcc OPT compiles. [Bug 1092952, 1091967] Align LIBS_GUI with Tk
+	head needs.
+
+2004-12-29  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclDate.c: Regen
+	* generic/tclGetDate.y (TclDatelex): Fixed a problem where a
+	four-digit group with >=2 leading zeroes appeared to be a two-digit
+	group, leading to misinterpreting the time 0012 as 1200. [Bug 1090413]
+	* library/clock.tcl: Added code to interpret correctly months outside
+	the range 01-12 as reduced modulo 12 with a corresponding adjustment
+	to the year. [Bug 1092789]
+	* tests/clock.test: Added regression test cases for the above two bugs
+	* unix/Makefile.in: Added --no-lines to the 'bison' command line to
+	* win/Makefile.in: help constrain the number of diffs in a cvs checkin

+
+2004-12-20  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCompile.c: moved TclInitCompiledLocals to tclProc.c
+	* generic/tclProc.c: new static InitCompiledLocals to allow for a
+	single pass over the proc's arguments at proc load time (instead of
+	two as previously). TclObjInterpProc() now allocates the
+	compiledLocals on the tcl execution stack, using the new
+	TclStackAlloc/Free functions.
+
+2004-12-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclInterp.c (Tcl_LimitSetTime, TimeLimitCallback):
+	(TclLimitRemoveAllHandlers, TclInitLimitSupport): Set a timer event to
+	trigger when the time limit runs out. All the time limit actually does
+	is check to see if the time limit has been exceeded, but this is
+	enough to fix [Bug 1085023].
+	* generic/tclInt.h (struct Interp): Added a field to hold the token
+	for the timer event handler associated with the current time limit.
+	* generic/tclEvent.c (Tcl_UpdateObjCmd, Tcl_VwaitObjCmd): Add error
+	message when limit exceeded.
+	* tests/interp.test (interp-34.[89]): Check that time limits handle
+	the two cases reported in [Bug 1085023]
+
+	* generic/tclTimer.c (TclCreateAbsoluteTimerHandler): New internal
+	function that allows setting a timer handler that will be triggered at
+	(or after) a specific time instead of at some number of milliseconds
+	in the future. This is a candidate for future exposure via a TIP.

+	TclPushStackFrame and TclPopStackFrame that do the work of
+	Tcl_PushCallFrame and Tcl_PopCallFrame, but using frames allocated in
+	the execution stack - i.e., heap instead of C-stack. The core uses
+	these two new functions exclusively; the old ones remain for backwards

+
+2004-12-07  Don Porter	<dgp@users.sourceforge.net>

+
+2004-12-04  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclEncoding.c:	Different fix for [Bug 1077005].
+	* generic/tclEvent.c:	Broke apart TclpSetInitialEncodings() on
+	* generic/tclInt.h:	Windows into TclpSetInterfaces(), that is
+	* unix/tclUnixInit.c:	fundamentally essential, and the initialization
+	* win/tclWinInit.c:	of the system encoding, which is not. Made
+	the TclpSetInterfaces call part of TclInitSubsystems so it cannot be
+	overlooked.
+
+2004-12-03  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* changes: updated for 8.5a2 release
+
+2004-12-02  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclUtil.c (TclSetProcessGlobalValue): Handle the case where
+	a ProcessGlobalValue might be assigned to itself.
+
+	* generic/tclEncoding.c (MakeFileMap): Correct refcounting errors
+	managing values returned by TclPathPart (with refCount of 1!) that led
+	to a memory leak. [Bug 1077474].
+
+2004-12-02  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclPathObj.c:  fix and new tests for [Bug 1074671] to ensure
+	* tests/fileSystem.test: tilde paths are not returned specially by
+	'glob'.
+
+2004-12-02  Kevin B. Kenny  <kennykb@acm.org>
+
+	* win/Makefile.in: Added a 'sed' in the setting of ROOT_DIR_NATIVE to
+	compensate for a bug in cygpath (at least version 1.36) that leaves a
+	trailing backslash on the end of the converted path.
+
+2004-12-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclInterp.c (Alias,Target,Master): Rewrote these so that the
+	aliases that refer to an interpreter are stored in a list and not a
+	hashtable (which was only ever a convenience, and forced the use of a
+	global mutex to generate keys!) [FRQ 1077210]
+	* generic/tclNamesp.c (numNsCreated): Moved into thread-local storage
+	to remove a global mutex. [FRQ 1077210]
+
+2004-12-01  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclUtil.c (TclGetProcessGlobalValue): Narrowed the scope of
+	mutex locks.
+
+	* generic/tclUtil.c:		Updated Tcl_GetNameOfExecutable() to
+	* generic/tclEncoding.c:	make use of a ProcessGlobalValue for
+	* generic/tclEvent.c:		storing the executable name. Added
+	internal routines Tcl(Get|Set)ObjNameOfExecutable() to access that
+	storage in Tcl_Obj, rather than string format.
+
+	* unix/tclUnixFile.c:	Rewrote TclpFindExecutable() to use
+	* win/tclWinFile.c:	TclSetObjNameOfExecutable to store the
+	executable name it computes.
+
+	* generic/tclInt.h:	Added internal stub entries for
+	* generic/tclInt.decls: TclpFindExecutable and
+	Tcl(Get|Set)ObjNameOfExecutable.
+
+	* generic/tclIntDecls.h: make genstubs
+	* generic/tclStubInit.c:
+
+	* generic/tclCmdIL.c:	Retrieve executable name in Tcl_Obj form
+	* win/tclWinPipe.c:	instead of string form.
+
+	* unix/tclUnixTest.c:	Update [testfindexecutable] command to use new
+	internal interfaces.
+
+	* generic/tclEncoding.c:	Moved TclpSetInitialEncodings() call
+	from Tcl_FindExecutable() into TclInitEncodingSubsystem(). This is
+	important on Windows where it establishes whether the "ascii" or
+	"unicode" set of system routines will be used, and that needs to be
+	done earlier to support filesystem operations. [Bug 1077005]
+
+2004-12-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* tests/winDde.test: Rewritten to use tcltest2 features more
+	thoroughly (reducing the [catch] count!) and fix the problem with
+	winDde-6.1 being out of synch with the implementation.
+
+2004-11-30  Don Porter	<dgp@users.sourceforge.net>
+
+	* library/init.tcl ([unknown]): Restored the save/restore of the
+	variables ::errorCode and ::errorInfo. This is needed when the
+	[::bgerror] command is auto-loaded (as it is by Tk).
+
+	Patch 976520 reworks several of the details involved with
+	startup/initialization of the Tcl library, focused on the activities
+	of Tcl_FindExecutable().
+
+	* generic/tclIO.c:	Removed bogus claim in comment that encoding
+	"iso8859-1" is "built-in" to Tcl.
+
+	* generic/tclInt.h:	Created a new struct ProcessGlobalValue,
+	* generic/tclUtil.c:	routines Tcl(Get|Set)ProcessGlobalValue, and
+	function type TclInitProcessGlobalValueProc. Together, these take care
+	of the housekeeping for "values" (things that can be held in a
+	Tcl_Obj) that are global across a whole process. That is, they are
+	shared among multiple threads, and epoch and mutex protection must
+	govern the validity of cached copies maintained in each thread.
+
+	* generic/tclNotify.c:	Modified TclInitNotifier() to tolerate being
+	called multiple times in the same thread.
+	* generic/tclEvent.c:	Dropped the unused argv0 argument to
+	TclInitSubsystems(). Removed machinery to unsure only one
+	TclInitNotifier() call per thread, now that that is safe. Converted
+	Tcl(Get|Set)LibraryPath to use a ProcessGlobalValue, and moved them to
+	tclEncoding.c.
+	* generic/tclBasic.c:	Updated caller.
+
+	* generic/tclInt.h:	TclpFindExecutable now returns void.
+	* unix/tclUnixFile.c:
+	* win/tclWinFile.c:
+	* win/tclWinPipe.c:
+
+	* generic/tclEncoding.c: Built new encoding search initialization on a
+	foundation of ProcessGlobalValues, exposing new routines
+	Tcl(Get|Set)EncodingSearchPath. A cache of a map from encoding name to
+	directory pathname keeps track of where encodings are available for
+	loading. Tcl_FindExecutable greatly simplified into just three
+	function calls. The "library path" is now misnamed, as its only
+	remaining purpose is as a foundation for the default encoding search
+	path.
+
+	* generic/tclInterp.c:	Inlined the initScript that is evaluated by
+	Tcl_Init(). Added verification after initScript evaluation that Tcl
+	can find its installed *.enc files, and that it has initialized
+	[encoding system] in agreement with what the environment expects.
+	[tclInit] no longer driven by the value of $::tcl_libPath; it largely
+	constructs its own search path now, rather than attempt to share one
+	with the encoding system.
+
+	* unix/tclUnixInit.c:	TclpSetInitialEncodings factored so that a new
+	* win/tclWinInit.c:	routine TclpGetEncodingNameFromEnvironment can
+	reveal that Tcl thinks the [encoding system] should be, even when an
+	incomplete encoding search path, or a missing *.enc file won't allow
+	that initialization to succeed. TclpInitLibraryPath reworked as an
+	initializer of a ProcessGlobalValue.
+
+	* unix/tclUnixTest.c:	Update implementations of [testfindexecutable],
+	[testgetdefenc], and [testsetdefenc].
+
+	* tests/unixInit.test:	Corrected tests to operate properly even when
+	a value of TCL_LIBRARY is required to find encodings.
+
+	* generic/tclInt.decls: New internal stubs: TclGetEncodingSearchPath,
+	TclSetEncodingSearchPath, TclpGetEncodingNameFromEnvironment. These
+	are candidates for public exposure by future TIPs.
+
+	* generic/tclIntDecls.h: make genstubs
+	* generic/tclStubInit.c:
+
+	* generic/tclTest.c:	Updated [testencoding] to use
+	* tests/encoding.test:	Tcl(Get|Set)EncodingSearchPath.	 Updated tests.
+
+2004-11-30  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl: Corrected the regular expressions that match a
+	time zone to allow for time zones specified as +HH or -HH.
+	* tests/clock.test: Added regression test case for the above issue.
+	Thanks to Rolf Ade for reporting this issue [http://wiki.tcl.tk/13094]
+	* win/tclWinDde.c (Tcl_DdeObjCmd): Corrected a typo that caused a
+	compilation failure on VC++.
+
+2004-11-29  Andreas Kupries <andreask@activestate.com>
+
+	* win/Makefile.in (install-libraries): Brought entry '2004-10-26 Don
+	Porter (Tcl Modules)' into the windows world, actually the
+	win/configure buildsystem. The other windows buildsystems (.vc, .bc)
+	still have to be updated as well.
+
+2004-11-26  Andreas Kupries <andreask@activestate.com>
+
+	* win/tclWinDde.c (ExecuteRemoteObject): Removed bogus semicolon found
+	at the end of the header for the function definition, terminating it
+	early and preventing a compile. This is likely a fix for '2004-11-25
+	Donal'. I have to conclude that it is also unknown if the other
+	changes to this file actually pass the testsuite. Running testsuite
+	... They don't. winDde-6.1 fails. This is only a message discrepance,
+	i.e. not too bad. Leaving resolution of that to Pat and Donal.
+
+2004-11-26  Don Porter	<dgp@users.sourceforge.net>
+
+	* library/auto.tcl (tcl_findLibrary): Made sure the uniquifying
+	operations on the search path does not also normalize. [Bug 1072136]
+
+2004-11-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* unix/configure.in: Simplify the code to check for correctness of
+	strstr, strtoul and strtod.
+	* unix/tcl.m4 (SC_TCL_CHECK_BROKEN_FUNC): Split a complex stanza out
+	of configure.in into its own function. Also force it to do the right
+	thing with cacheing of results of AC_TRY_RUN to deal with issue raised
+	in [Patch 1073524]
+
+	* doc/foreach.n: Added simple example. [FRQ 1073334]
+
+2004-11-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclProc.c (TclObjInterpProc):	    Make it so that only
+	* generic/tclIndexObj.c (Tcl_WrongNumArgs): [proc] instances do
+	* tests/indexObj.test (indexObj-5.7):	    quoting of their first
+	arguments, so keeping [Bug 942757] fixed and making [Bug 1066837] be
+	fixed as well. Done with a load of #ifdef-ery because this hack is so
+	ugly nobody should keep it around once Itcl's fixed.
+
+2004-11-25  Reinhard Max  <max@suse.de>
+
+	* tests/tcltest.test: The order in which [glob] returns the file names
+	is undefined, so tests should not depend on it.
+
+2004-11-25  Zoran Vasiljevic <vasiljevic@users.sf.net>
+
+	* doc/Thread.3:
+	* doc/Notifier.3: Added changes from the core-8-4-branch
+
+2004-11-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/dde.n: Synchronized the documentation of the commands with the
+	header of the docs and what the package actually does. Thanks to
+	Andreas Kupries for spotting this.
+	* win/tclWinDde.c (Tcl_DdeObjCmd): Much cleanup of argument parsing
+	code.
+
+2004-11-24  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tclPort.h: Relative include of tclWinPort.h returned as it
+	was requiring me set -I$(tcl_root)/win for my extensions that need to
+	include tclInt.h and doesn't appear to serve any purpose for windows
+	builds.
+
+2004-11-24  Kevin B. Kenny  <kennykb@acm.org>
+
+	* unix/tcl.m4 (SC_ENABLE_THREADS): Corrected bad check for 3-argument
+	readdir_r [Bug 1001325].
+	* unix/configure: Regenerated.
+	* unix/tclUnixNotfy.c: Corrected all uses of 'select' to manage their
+	masks using the FD_CLR, FD_ISSET, FD_SET, and FD_ZERO macros rather
+	than bit-whacking that failed under Solaris-Sparc-64. [Bug 1071807]
+	* win/tclWinInit.c (TclpInitLibraryPath): Removed unused vars 'pathc'
+	and 'pathv' that caused compilation problems on VC++ with
+	--enable-symbols.
+
+2004-11-24  Don Porter	<dgp@users.sourceforge.net>
+
+	* unix/tcl.m4 (SC_ENABLE_THREADS): Corrected failure to determine the
+	number of arguments for readdir_r on SunOS systems. [Bug 1071701]
+
+	* unix/configure:	autoconf-2.57
+
+	* generic/tclCmdIL.c (InfoVarsCmd):	Corrected segfault in new
+	* tests/info.test (info-19.6):	trivial matching branch [Bug 1072654]
+
+2004-11-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* tools/man2html.tcl, tools/man2html1.tcl: Update to use Tcl 8.4.
+	* tools/man2html2.tcl: Fix broken .SS handling.
+
+2004-11-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* unix/Makefile.in: Add (commented-out) code to integrate tclConfig.h
+	into the dependency tree and 'make distclean'. [Bug 1068171]
+
+	* generic/tclResult.c (Tcl_AppendResultVA): Remove call to
+	Tcl_GetStringResult to speed up repeated calls to Tcl_AppendResult
+	with the side effect that code that wants to access interp->result
+	should always call Tcl_GetStringResult first. See [Patch 1041072]
+	discussion for more details.
+
+2004-11-22  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/configure: Regen.
+	* unix/tcl.m4 (SC_TCL_64BIT_FLAGS): Define HAVE_TYPE_OFF64_T only when
+	off64_t, open64(), and lseek64() are defined. IRIX 5.3 is known to not
+	include an open64 function. [Bug 1030465]
+
+2004-11-22  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/configure: Regen.
+	* unix/tcl.m4 (SC_ENABLE_THREADS): Check for a 2 argument version of
+	readdir_r that is known to exists under IRIX 5.3.
+	* unix/tclUnixThrd.c (TclpReaddir): Use either 2 arg or 3 arg version
+	of readdir_r. [Bug 1001325]
+
+2004-11-22  Don Porter	<dgp@users.sourceforge.net>
+
+	* unix/tclUnixInit.c (TclpInitLibraryPath): Purged dead code that used
+	* win/tclWinInit.c (TclpInitLibraryPath):  to extend the "library
+	path". Search path construction for init.tcl is now done within the
+	[tclInit] proc.
+	* generic/tclInterp.c:	Restored several directories to the search
+	* tests/unixInit.test:	path used to locate init.tcl within [tclInit].
+	This change does not restore any directories to the encoding search
+	path, so should still avoid the price of an unreasonably large number
+	of filesystem accesses during encoding initialization at startup
+	[Bug 976438]
+
+2004-11-22  Vince Darley  <vincentdarley@users.sourceforge.net>

+	* tests/unixInit.test: Removed "knownBug" constraints to prompt bug
+	fixing before 8.5a2 release.
+
+2004-11-19  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/Makefile:
+	* unix/configure.in:
+	* unix/tclUnixInit.c (MacOSXGetLibraryPath): changed detection of tcl
+	framework build when determining tclLibPath from overloaded
+	TCL_LIBRARY to configuration define TCL_FRAMEWORK. [Bug 1068088]
+
+	* unix/configure: autoconf-2.57
+	* unix/tclConfig.h.in: autoheader-2.57
+
+2004-11-18  Don Porter	<dgp@users.sourceforge.net>
+
+	* doc/SaveResult.3:	Documentation for Tcl_*InterpState (TIP 226).
+
+	* generic/tclEvent.c (HandleBgErrors):	Simplified program flow.
+
+	* tests/basic.test:	Updated functional (not testing) uses of
+	* tests/io.test:	[bgerror] to make use of [interp bgerror].
+	* tests/socket.test:
+	* tests/timer.test:
+
+	* tests/interp.test (interp-36.*):	[interp bgerror] tests.
+
+	* generic/tclInterp.c:	Corrected [interp bgerror] error messages.
+
+2004-11-18  Reinhard Max  <max@suse.de>
+
+	* unix/tcl.m4 (SC_CONFIG_MANPAGES): Applied an improved version of
+	* unix/configure.in:		    [Patch 996085], that introduces
+	* unix/Makefile.in:		    --enable-man-suffix.
+
+	* unix/installManPage:		    added
+	* unix/mkLinks.tcl:		    removed
+	* unix/mkLinks:			    removed
+	* unix/configure:		    generated
+
+	* unix/Makefile.in:		    Don't install tclConfig.h .
+
+2004-11-17  Don Porter	<dgp@users.sourceforge.net>
+
+	* unix/configure.in: The change below reveals that the public data
+	type Tcl_StatBuf relies on config information. For now, disabled the
+	use of the tclConfig.h file until its full impact on Tcl's interface
+	can be assessed.
+
+	* unix/configure:	autoconf-2.57
+
+	* generic/tcl.h:	Moved the #include "tclConfig.h" out of
+	* generic/tclInt.h:	tcl.h.	The config settings are not part of
+	* generic/tclPort.:	the public interface, and having it there
+	breaks compiled against uninstalled Tcl and extensions using
+	autoconf-2.5*.
+
+2004-11-16  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* unix/tclUnixChan.c (TtySetOptionProc): fixed crash configuring
+	-ttycontrol on a channel. [Bug 1067708]
+
+2004-11-16  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIOUtil.c (TclFSEpochOk): There were two code paths via
+	which the thread copy of filesystemEpoch could be synched with the
+	master copy, but only one kept the filesystem list cache up to date.
+	Fix routes everything through a single code path. [Bug 1035775].
+
+2004-11-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Stop architecture flags to 'ld' from
+	getting lost when [load] is disabled. [Bug 1016796]
+
+2004-11-16  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tcl.h:
+	* unix/configure.in: changed HAVE_CONFIG_H to HAVE_TCL_CONFIG_H.
+
+	* unix/configure: autoconf-2.57
+
+2004-11-15  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclInt.h: Added comment warning that the old ERR_IN_PROGRESS
+	and ERROR_CODE_SET flag values should not be re-used for the sake of
+	those extensions that have accessed them.
+
+	* generic/tclCmdMZ.c (Tcl_TraceObjCmd): Fixed Bug 1065378 which failed
+	* tests/trace.test (trace-33.1):	to permit a variable trace
+	created with [trace variable] to be destroyed with [trace remove].
+	Thanks to Keith Vetter for the report.
+
+2004-11-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/tclvars.n: Added section to documentation on global variables
+	that are specific to tclsh and wish. [Patch 1065732]
+
+2004-11-12  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* generic/tclEncoding.c (TableFromUtfProc): correct crash condition
+	when TCL_UTF_MAX == 6. [Bug 1004065]
+
+2004-11-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/interp.n: Basic documentation of the TIP#221 API.
+
+2004-11-12  Don Porter	<dgp@users.sourceforge.net>
+
+	TIP #221 IMPLEMENTATION
+	* generic/tclBasic.c:	Define [::tcl::Bgerror] in new interps.
+	* generic/tclEvent.c:	Update Tcl_BackgroundError to make use of the
+				registered [interp bgerror] command.
+	* generic/tclInterp.c:	New [interp bgerror] subcommand.
+	* tests/interp.test:	syntax tests updated.
+
+	TIP #226 IMPLEMENTATION
+	* generic/tcl.decls:	Stubs for Tcl_(Save|Restore|Discard)InterpState
+	* generic/tcl.h:	New public opaque type, Tcl_InterpState.
+	* generic/tclInt.h:	Drop old private declarations. Add
+				Tcl(Get|Set)BgErrorHandler

+	TIP #227 IMPLEMENTATION
+	* generic/tcl.decls:	Stubs for Tcl_(Get|Set)ReturnOptions.
+	* generic/tclInt.h:	Drop old private declarations.
+	* generic/tclResult.c:	Tcl_*ReturnOptions implementations.
+	* generic/tclCmdAH.c:	Update callers.
+	* generic/tclMain.c:
+
+	* generic/tclDecls.h:	make genstubs
+	* generic/tclStubInit.c:
+
+	* unix/tclAppInit.c:	Removed tclConfig.h #include, now that tcl.h
+				takes care of it for us.
+
+	* generic/tclInt.h:	Moved verification of ptrdiff_t typedef from
+	* generic/tclExecute.c: multiple .c files into one common header where
+	* generic/tclVar.c:	it is verifiably after tclConfig.h inclusion.
+
+2004-11-12  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tcl.h:
+	* generic/tclInt.h:
+	* unix/Makefile.in: include tclConfig.h from tcl.h and install it as a
+	public header. Normalized compiler include path order to
+	-I${BUILD_DIR} -I${UNIX_DIR} -I${GENERIC_DIR}.
+
+	* unix/dltest/Makefile.in: add ${BUILD_DIR}/.. to include path to pick
+	up tclConfig.h.
+
+	* unix/tclUnixInit.c: moved check for HAVE_CFBUNDLE define after
+	#include "tclInt.h" to ensure tclConfig.h has been included.
+
+2004-11-12  Reinhard Max  <max@suse.de>
+
+	* unix/config.h.in:
+	* unix/tclConfig.h.in:	renamed
+
+	* unix/Makefile.in:	Completed support for config header,
+	* unix/configure.in:	fixed building outside of the unix dir,
+	* unix/tclAppinit.c:	and reflected the name change of config.h.
+	* generic/tclInt.h:
+
+	* unix/configure:	generated
+
+2004-11-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* unix/config.h.in:	Allow configure to put all the C #defs into
+	* unix/configure.in:	a file (called config.h) so that Unix builds
+	* unix/tcl.m4:		now take far fewer lines of scrollback to
+	* unix/Makefile.in:	proceed (making it less likely that any errors
+	* generic/tclInt.h:	or warnings will get missed).
+	* unix/tclAppInit.c:	Part of the TIP#34 upgrades.
+
+	* unix/tcl.m4, unix/tclUnixPort.h: Check for pthread_attr_get_np in
+	<pthread.h> before forcing the use of <pthread_np.h> to make things
+	work on NetBSD 2.0. [Bug 1064882]
+
+	* doc/binary.n, doc/upvar.n: More minor fixes.
+
+2004-11-12  Daniel Steffen  <das@users.sourceforge.net>
+
+	* doc/CrtChannel.3:
+	* doc/Interp.3:
+	* doc/Limit.3:
+	* doc/binary.n:
+	* doc/dict.n:
+	* doc/tm.n:
+	* doc/upvar.n: fixed *roff errors uncovered by running 'make html'.
+
+	* tools/tcltk-man2html.tcl: added faked support for bullet point
+	lists, i.e. *nroff ".IP \(bu" syntax.
+
+2004-11-11  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tests/fCmd.test:
+	* unix/tclUnixFCmd.c (TraverseUnixTree): added option to rewind() the
+	readdir() loop whenever the source hierarchy has been modified by
+	traverseProc (e.g. by deleting files); this is required to ensure
+	complete traversal of the source hierarchy on certain filesystems like
+	HFS+. Added test for failing recursive delete on Mac OS X that was due
+	to this. [Bug 1034337]
+
+	* generic/tclListObj.c (Tcl_ListObjReplace): use memmove() instead of
+	manual copy loop to shift list elements. Decreases time spent in
+	Tcl_ListObjReplace() from 5.2% to 1.7% of overall runtime of tclbench
+	on a ppc 7455 (i.e. 200% speed increase). [Patch 1064243]
+
+	* generic/tclHash.c: hoisted some constant pointer dereferences out of
+	loops to eliminate redundant loads that the gcc optimizer didn't deal
+	with. Decreases time spend in Tcl_FindHashEntry() by 10% over a full
+	run of the tcl testuite on a ppc 7455. [Patch 1064243]
+
+	* tests/fileName.test:
+	* tests/fileSystem.test:
+	* tests/io.test:
+	* tests/msgcat.test:
+	* tests/tcltest.test:
+	* tests/unixInit.test: fixed bugs causing failures when running tests
+	with -tmpdir arg not set to working dir.
+
+	* macosx/Makefile: corrected path to html help inside framework.
+	Prevent parallel make from building several targets at the same time.
+
+	* macosx/tclMacOSXFCmd.c (struct fileinfobuf): force struct to be
+	packed to prevent failures when builing with -malign=natural.
+
+2004-11-10  Andreas Kupries <andreask@activestate.com>
+
+	* unix/tclUnixChan.c: [Bug 727786]. Exterminated the code marked
+	DEPRECATED. This code has not been used in over a year now, and we
+	have no complaints.
+
+2004-11-08  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinPipe.c: The pipe channel driver now respects the -blocking
+	option when closing is the same way the UNIX side works. This is to
+	avoid a hung shell when exiting due to open pipes that refuse to close
+	in a graceful manner.
+	* doc/open.n: Added a note about -blocking 0 and lack of exit status
+	as it had never been documented. [Bug 947693]
+
+	***POTENTIAL INCOMPATIBILITY***
+
+	Scripts that use async pipes on windows, must (like the UNIX side) set
+	-blocking to 1 before calling [close] to receive the exit status.
+
+2004-11-07  David Gravereaux <davygrvy@pobox.com>
+
+	* tests/winFile.test: added contraint to winFile-4.0 to prevent it
+	being run on NT4 [Bug 981829]
+
+2004-11-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* tests/reg.test: Major reorganization so that this file is much
+	easier for a normal Tcl maintainer to comprehend. The test flags are
+	still very cryptic, but they appear to have to be that way. The number
+	of skipped tests has increased, but now the skipped tests have much
+	more meaningful content.
+
+	* tests/tm.test (genpaths): Add a [file normalize] so we pick up
+	Windows drive letters, etc. [Bug 1053568]
+
+2004-11-04  Don Porter	<dgp@users.sourceforge.net>
+
+	* changes:	Updates toward an 8.5a2 release.
+
+2004-11-03  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl (FreeScan): Fixed a bug where scanning "Monday"
+	with a base time other than midnight incorrectly carried the base time
+	forward.
+
+	* test/clock.test (clock-33.{5,5a}): Made the test failure more
+	informative.
+
+	* tests/clock.test (clock-34.{28,44,45,46}): Removed 'knownBug'
+	constraints from tests that no longer fail.
+
+	Thanks to Don Porter for reporting these.
+
+2004-11-03  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tcl.h:		Moved the preprocessor logic
+	* generic/tclDecls.h:		from tclInt.h of setting the
+	* generic/tclInt.h:		TCL_STORAGE_CLASS macro to the
+	* generic/tclIntDecls.h:	tcl*Decls.h files now that no
+	* generic/tclIntPlatDecls.h:	use of EXTERN is left in tclInt.h.
+	* generic/tclPlatDecls.h:	Proto for Tcl_Main moved in tcl.h
+	* win/tclWinPort.h:		to prior the inclusion of the Stubs
+	headers as they are now resetting TCL_STORAGE_CLASS. Removed
+	extraineous reset from tclWinPort.h. [Patch 1055668]
+
+	* generic/tclCompile.h: Removed extrainious reset of TCL_STORAGE_CLASS
+	missed in my last edit.
+
+2004-11-03  Don Porter	<dgp@users.sourceforge.net>
+
+	* library/init.tcl ([unknown]): Corrections to the 2004-10-25 mods to
+	Aunt ??? in [unknown]. Flaws revealed by Itcl test suite, which still
+	apparently relies on this brokenness. Also added comment suggesting
+	the error message that any code using this hack *ought* to receive in
+	reply.
+
+	* generic/tclTrace.c (TclCallVarTraces):  Improved ability to debug
+	* tests/incr-old.test (incr-old-2.6):	  errors during variable
+	* tests/incr.test (incr-{1,2}.28):	  traces by preserving the
+	* tests/set.test (set-{2,4}.4):		  -errorinfo data.
+	* tests/trace.test (trace-33.1):	  [Bug 527164]
+
+2004-11-02  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tclInt.h: added a check for #ifdef __cplusplus around the
+	#define of MODULE_SCOPE. About the only time it would be problem is
+	when someone is statically linking to Tcl and accessing internals from
+	a C++ file and has name mangling issues from the lack of "C" after
+	'extern' [Patch 1055668].
+	* generic/tclCompile.h: Exchanged use of the EXTERN macro to the new
+	MODULE_SCOPE macro. Lowered exported internals count by 35. [Patch
+	1055668]
+	* win/tclWinInt.h:
+	* win/tclWinPort.h: exported internals dropped by a count of 14.
+	* generic/tclFileSystem.h: Added use of MODULE_SCOPE on protos.
+	* generic/tclRegexp.h: manipulating TCL_STORAGE_CLASS unnecessary.
+
+2004-11-02  Don Porter	<dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl:		Corrected some misleading
+	* tests/tcltest.test (tcltest-26.1,2):	displays of ::errorInfo and
+	::errorCode information when the -setup, -body, and/or -cleanup scripts
+	return an unexpected return code. Thanks to Robert Seeger for the fix.
+	[RFE 1017151].
+
+2004-11-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclExecute.c (TclExecuteByteCode): Improved version of the
+	NaN fix from Miguel Sofer. [Bug 761471]
+
+2004-11-02  Kevin Kenny	 <kennykb@acm.org>
+
+	* library/tzdata/America/Cuiaba: Change to DST rules for
+	* library/tzdata/America/Havana: autumn of 2004.
+	[ftp://elsie.nci.nih.gov/pub/tzdata2004g.tar.gz]
+
+	* tools/tclZIC.tcl: Updated to be compatible with recent changes in
+	library/clock.tcl.
+
+2004-11-02  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* win/tclWinFile.c: Simplify TclpUtime to use Tcl_FSGetNativePath, and
+	add comments.
+
+2004-11-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclInt.h: Change uses of EXTERN to MODULE_SCOPE (defined in
+	this file too to be 'extern' if not overridden) as nothing declared in
+	tclInt.h is supposed to be visible outside the Tcl core. If there *is*
+	anything that extensions are actually using, we can open this up later
+	on. [Patch 1055668]
+
+	* doc/CrtChannel.3 (Tcl_GetChannelMode): Add synopsis. [Bug 1058446]
+
+2004-11-01  Kevin B. Kenny  <kennykb@acm.org>
+
+	* win/tclWinFile.c (FromCTime, TclpUtime): Replaced a call to the
+	Posix 'utime' function with calls to Windows-API equivalents, to avoid
+	a bug where the VC++ versions misconvert times across a Daylight
+	Saving Time boundary. [Bug 926106]
+	* win/tclWinInt.h (TclWinProcs):
+	* win/tclWin32Dll.c (asciiProcs, unicodeProcs): Removed now-unused
+	reference to 'utime'.
+	* tests/cmdAH.test (cmdAH-24.12): Added test case for the above bug.
+
+2004-11-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclExecute.c (TclExecuteByteCode): Make INST_EQ and friends
+	handle NaN correctly in all cases. [Bug 761471]
+
+	* generic/tclNamesp.c (NamespaceInscopeCmd): Make the error message
+	generation the same as in NamespaceEvalCmd().
+	(Tcl_Import): Rationalized to use Tcl_EvalObjv().
+
+2004-10-31  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* tests/io.test (io-40.3): Convert umask2 test constraint into a form
+	that most people will be able to satisfy.
+
+	* tests/cmdAH.test (cmdAH-8.45): Removed broken test constraint. It
+	didn't do what it was intended to do, and it implied the other correct
+	constraint. [Bug 1053908]
+
+	* generic/tclCmdIL.c (InfoGlobalsCmd):
+	* tests/info.test (info-8.4): Strip leading global-namespace
+	specifiers from the pattern argument. [Bug 1057461]
+
+2004-10-30  Kevin Kenny	 <kennykb@acm.org>
+
+	* generic/clock.c: Replaced WIN32 macro with __WIN32__. [Bug 1054357].
+	Thanks to David Gravereaux for the patch.
+	* win/tclWinFile.c: Removed a long-standing bug that causes incorrect
+	conversion between file time and UTC time if the file time is recorded
+	in a different Daylight Saving Time status than the current one. [Bug
+	926106]
+
+2004-10-29  Don Porter	<dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl:	Correct reaction to errors in the
+	obsolete processCmdLineArgsHook.	[Bug 1055673]
+	* library/tcltest/pkgIndex.tcl:	Bump to tcltest 2.2.7
+	* unix/Makefile.in:
+	* tests/all.tcl:	Update to use [tcltest::configure].
+
+2004-10-29  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* library/tm.tcl (::tcl::tm::*): Use the core proc engine to generate
+	the wrong-num-args error messages for the path ensemble.
+
+	Ensembles can now (sometimes) rewrite the error messages of their
+	subcommands so they appear more like the arguments that the user
+	passed to the ensemble. Below is a description of changes involved in
+	doing this.
+
+	* tests/namespace.test (namespace-50.*): Tests of ensemble subcommand
+	error message rewriting.
+	* generic/tclProc.c (TclObjInterpProc): Make procedures implement
+	their wrong-num-args message using Tcl_WrongNumArgs instead of
+	something baked-at-home.
+	* generic/tclNamesp.c (TclIsEnsemble, NsEnsembleImplementationCmd):
+	Added test of ensemble-hood (available to rest of core) and made
+	ensembles set up the rewriting for Tcl_WrongNumArgs to take advantage
+	of.
+	* generic/tclInt.h (Interp.ensembleRewrite): Extra fields.
+	* generic/tclIndexObj.c (Tcl_WrongNumArgs): Add knowledge of what is
+	going on in ensembles' command rewriting so this command can generate
+	the right error message itself.
+	* generic/tclBasic.c (Tcl_CreateInterp, TclEvalObjvInternal): Added
+	code to initialize (as empty) the rewriting fields and reset them when
+	we leak outside an ensemble implementation.
+
+2004-10-28  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c (INST_START_CMD):
+	* tests/execute.test (execute-8.3): fix for execution stack corruption
+	[Bug 1055676]. Credit dgp for detective work and fix.
+
+2004-10-27  Don Porter	<dgp@users.sourceforge.net>
+
+	* tests/socket.test (socket-13.1):	Balanced [makeFile] and
+	[removeFile] commands.
+
+	* tests/clock.test:	Correct duplicate test names.
+	* tests/namespace.test:
+	* tests/string.test:
+	* tests/io.test (io-50.4):	Use namespace variables.
+
+2004-10-27  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tclInt.decls:	  The following 9 functions were moved from
+	* generic/tclInt.h:	  tclInt.h to the private/int Stubs table for
+	* generic/tclIntDecls.h:  use by the test suite. As tclTest.obj is
+	* generic/tclStubInit.c:  linked to the shell, these functions need
+	"blessed" status so as to always be exported from the library. Being
+	placed in the Stubs table guarantees this [Bug 1054748]:
+		TclpObjRemoveDirectory,	TclpObjCopyDirectory,
+		TclpObjCreateDirectory,	TclpObjDeleteFile,
+		TclpObjCopyFile,	TclpObjRenameFile,
+		TclpObjStat,		TclpObjAccess,
+		TclpOpenFileChannel
+
+	* tests/registry.test:	Fixed test files to load the correct
+	* tests/winDde.test:	registry and dde packages by using the info
+	* win/Makefile.in:	from makefiles to tell tcltest where to load
+	* win/makefile.vc:	them from. This avoids grabbing the wrong
+	package from $auto_path which might be the install point rather than
+	the dev location. Kudos to Jennifer Hom for adding -load and
+	-loadfile to the tcltest package. [Bug 926088]
+
+	* win/tclWinThrd.c (TclFinalizeLock): release the critical section
+	before deleting it. [Bug 731778]
+
+	* generic/tcl.h: Removed the file level 'extern "C" {' and the
+	coresponding closing block as it serves no purpose given that all the
+	function prototypes have the proper extern usage already.
+
+	* unix/tclAppInit.c:	When built as tcltest, TclThread_Init was
+	* win/tclAppInit.c:	getting called twice. First by Tcltest_Init,
+	then again in Tcl_AppInit. The call from Tcl_AppInit is now removed.
+
+2004-10-27  Andreas Kupries <andreask@activestate.com>
+
+	* tests/tm.test:  Expanded on the testsuite entered by Donal.
+	* library/tm.tcl: Even found bugs, these have been corrected.
+
+2004-10-26  Kevin Kenny <kennykb@acm.org>
+
+	* tests/format.test (format-19.1): Additional regression test for [Bug
+	868489].
+
+2004-10-27  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/*.n: Many small general documentation fixes.
+
+2004-10-26  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tclPipe.c (TclCleanupChildren): bad cast of resolvedPid
+	caused PIDs on win95 to go negative. winpipe-4.2 brought this to the
+	surface. Fixed with sprintf in place of TclFormatInt. Thanks to hgiese
+	[Patch 767676]
+
+2004-10-26  Andreas Kupries <andreask@activestate.com>
+
+	* library/tm.tcl (::tcl::tm::Defaults): Added a second [file dirname]
+	around the location of the executable. This fixes [Bug 1038705].
+	Instable of a bogus "foo/bin/lib" we now have the correct "foo/lib" as
+	a base path for modules.
+
+2004-10-26  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclParse.c (Tcl_SubstObj):	Fix for failed subst-12.3 test
+	* tests/subst.test (subst-12.3-5):	More tests for Bug 1036649.
+
+	* unix/Makefile.in (install-libraries): Updated the installation of
+	the http, msgcat, and tcltest packages to install as Tcl Modules on
+	Unix systems. Other platform Makefiles still need updating. [Patch
+	1054370]
+
+	* tests/basic.test:	Added missing constraints.
+	* tests/compile.test:
+	* tests/fileSystem.test:
+
+	* tests/init.test (init-2.8):	Updated to not rely on http package.
+
+2004-10-26  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclInt.h:
+	* generic/tclVar.c: removed more direct references to the VAR flags,
+	replaced with access macros.
+
+2004-10-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/expr.n: Clarified that non-num/non-bool literals require
+	quoting. [Bug 1027849]. Also listed booleans as acceptable values.
+
+2004-10-26  Kevin B. Kenny <kennykb@acm.org>
+
+	* library/clock.tcl (FreeScan): Fixed a bug that caused relative days
+	of the week in free-form [clock scan] to be evaluated in the wrong
+	time zone.
+	* tests/clock.test (clock-31.[456]): Made sure that there isn't an
+	env(TZ) or env(TCL_TZ) lying around that will override the time zone
+	that we're trying to establish with the simulated registry.
+	Both problems reported as [Bug 1054101].
+
+2004-10-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/string.n (map): Rewrote to clarify that we don't just map single
+	characters. [Bug 1048005]
+	* doc/info.n (procs): Clarified that the pattern argument may have
+	namespace separators in it. [Bug 1047928]
+
+	* tests/cmdAH.test (cmdAH-8.45): Simplify in the hope that the reasons
+	for [Bug 1053908] will become clearer.
+
+2004-10-25  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c (IllegalExprOperandType,TclExecuteByteCode):
+	Removed several DECACHE_INFO/CACHE_INFO pairs that are no longer
+	needed for protection because routines like Tcl_SetErrorCode() and
+	Tcl_AddErrorInfo() can no longer re-enter bytecode execution.
+
+	* generic/tclResult.c (TclProcessReturn): Bug fix. Be sure that a
+	missing -errorinfo option when code == TCL_ERROR causes the errorInfo
+	field to get reset.
+
+	* tests/thread.test (thread-4.4): Test depended on a ::errorInfo value
+	initialized to "". Added code to test to setup that requirement.
+
+	* library/auto.tcl:	Purged Tcl's script library of all
+	* library/clock.tcl:	remaining references to global vars
+	* library/init.tcl:	::errorInfo and ::errorCode.
+
+	* generic/tclMain.c (Tcl_Main): Updated to make use of
+	TclGetReturnOptions instead of ::errorInfo variable.
+
+	* generic/tclInterp.c (tclInit): Bug fix. Access dict variables with
+	[dict get], not array syntax.
+
+2004-10-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* tests/tm.test: Rewrote the tests to actually perform syntax checks
+	on the public API. Added a new test (currently failing) to indicate
+	that the test suite is not complete yet.
+	* library/tm.tcl (path): Rewrote to turn this command into an ensemble
+	to make it faster and simpler.
+
+2004-10-24  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCmdIL.c:
+	* generic/tclExecute.c:
+	* generic/tclInt.h:
+	* generic/tclTrace.c: defined new macros to get/set the flags of
+	variables. The only files that still access the flag values directly
+	are tclCompCmds.c, tclCompile.c, tclProc.c and tclVar.c
+
+2004-10-24  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (Tcl_LogCommandInfo,Tcl_AddObjErrorInfo): Shift
+	the initialization of errorCode to NONE to more central location.
+
+	* generic/tclEvent.c (BgError,Tcl_BackgroundError,HandleBgErrors):
+	Rewrite to build on the new TclGet/SetReturnOptions routines.
+
+	* generic/tclResult.c (TclGetReturnOptions): Add call to
+	Tcl_AddObjErrorInfo to be sure error fields are initialized.
+
+	* generic/tclResult.c (TclTransferResult): Rewrite to build on the new
+	TclGet/SetReturnOptions routines.
+
+2004-10-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/tm.n: Tightened up the documentation.
+	* tests/tm.test: Created (with partially dummy content) so TIP#189 can
+	be marked Final.
+
+	* generic/tclNamesp.c (NsEnsembleImplementationCmd): Make ensembles
+	cut their implementations out of error traces. This is the right thing
+	to do more often than not.
+
+2004-10-22  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl: Fixed a typo where the fallback time zone became
+	::localtime instead of :localtime. Fixed a bug where time zone names
+	containing hyphens could not be loaded.
+	* tests/clock.test: Added regression test cases that covers both bugs.
+	Thanks to Todd M. Helfter <tmh@jumpgate.itsp.purdue.edu> for finding
+	these bugs.
+
+2004-10-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclExecute.c (TclCompEvalObj, Tcl_ExprObj):
+	* generic/tclProc.c (TclProcCompileProc): Always call object
+	freeIntRepProc's in the same way.
+
+2004-10-22  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclVar.c: fixed bug in commit of 2004-07-23, which was
+	causing a leak of Proc structures and failure of compile-12.1. Two
+	lines were 'zombies' from the previous way localVarNames worked.
+	Credit dgp for finding this.
+
+2004-10-21  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclInt.h (Interp):
+	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
+	* generic/tclResult.c (GetKeys,ReleaseKeys,etc.): Moved the key values
+	of the return options dictionary out of private fields of the Interp
+	struct and into thread-static values managed in tclResult.c.
+
+	* generic/tclCmdAH.c (Tcl_CatchObjCmd, Tcl_ErrorObjCmd): Updated to
+	call the new TclGet/SetReturnOptions routines to do much of their
+	work.
+
+	* generic/tclInt.h (TclGetReturnOptions,TclSetReturnOptions):
+	* generic/tclResult.c (TclGetReturnOptions,TclSetReturnOptions): New
+	utility routines to get/set the return options of an interp. Intent is
+	that these routines will be converted to public routines after TIP
+	approval.
+
+	* generic/tclCmdMZ.c (TclProcessReturn,TclMergeReturnOptions):
+	* generic/tclResult.c (TclProcessReturn,TclMergeReturnOptions): Move
+	internal utility routines from tclCmdMZ.c to tclResult.c.
+
+	* generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp):
+	* generic/tclResult.c (TclTransferResult): Rework so that
+	iPtr->returnOpts can be NULL when there are no special options.
+
+	* generic/tclResult.c (TclRestoreInterpState): Plug potential memory
+	leak.
+
+2004-10-21  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclBasic.c: Various changes to [clock format] that,
+	* generic/tclClock.c: together, make it roughly twice as fast
+	* generic/tclInt.h:   while all tests in the test suite
+	* library/clock.tcl:  continue to pass.
+
+2004-10-20  Andreas Kupries <andreask@activestate.com>
+
+	* win/Makefile.in (install-msgs):   Fixed a problem with the
+	* win/Makefile.in (install-tzdata): installation of timezone data and
+	message catalogs. They used the installed tcl library directory, not
+	the source library. Before it was installed. Switched to source lib
+	dir. Thanks to Kevin for the help in figuring this out.
+
+2004-10-20  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclThreadTest.c (ThreadEventProc): Corrected subtle bug
+	where the returned (char *) from Tcl_GetStringResult(interp) continued
+	to be used without copying or refcounting, while activity on the
+	interp continued. That's not safe, and recent changes demonstrated the
+	lack of safety with failing tests thread-4.3 and thread-4.5.
+
+2004-10-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclDictObj.c (DictWithCmd): Make sure all paths (that are
+	not themselves error paths) do not lose the result code.
+
+2004-10-19  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclInt.h (Tcl*InterpState):		New internal routines
+	* generic/tclResult.c (Tcl*InterpState):	TclSaveInterpState,
+	TclRestoreInterpState, and TclDiscardInterpState are superior
+	replacements for Tcl_(Save|Restore|Discard)Result. Intent is that
+	these routines will be converted to public routines after TIP
+	approval. Interfaces for these routines were shamelessly stolen from
+	Itcl.
+
+	* generic/tclBasic.c (TclEvalObjvInternal):
+	* generic/tclDictObj.c (DictUpdateCmd, DictWithCmd):
+	* generic/tclIOGT.c (ExecuteCallback):
+	* generic/tclTrace.c (Trace*Proc,TclCheck*Traces,TclCallVarTraces):
+	Callers of Tcl_*Result updated to call the new routines. The calls
+	were relocated in several cases to perform save/restore operations
+	only when needed.
+
+	* generic/tclEvent.c (HandleBgErrors):
+	* generic/tclFCmd.c (CopyRenameOneFile): Calls to Tcl_*Result that
+	were eliminated because they appeared to serve no useful purpose,
+	typically saving/restoring an error message, only to throw it away.
+
+2004-10-18  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
+	* generic/tclCmdAH.c (Tcl_CatchObjCmd):

+	* generic/tclCompCmds.c (TclCompileReturnCmd):
+	* generic/tclExecute.c (TclCompEvalObj):
+	* generic/tclInt.h (Interp):
+	* generic/tclProc.c (TclUpdateReturnInfo): Place primary storage of
+	the -level and -code information in private fields of the Interp
+	struct, rather than in a DictObj. This should significantly improve
+	performance of TclUpdateReturnInfo.
+
+2004-10-17  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclResult.c: removed unused variable [Bug 1048588]. Thanks
+	to Daniel South.
+
+2004-10-15  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c (TclProcessReturn):	Now that primary
+	* generic/tclProc.c (TclUpdateReturnInfo):	storage for the
+	errorInfo and errorCode values are internal fields, we can set them at
+	the time of the [return] command, and not have to wait until the
+	specified number of "-level"s have popped.
+
+	* generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp)

+	* generic/tclProc.c (TclUpdateReturnInfo):
+	* generic/tclResult.c (Tcl_ResetResult, TclTransferResult):
+	* generic/tclTrace.c (CallVarTraces):
+	Reworked management of the "errorInfo" data of an interp. That
+	information is now primarily stored in a new private (Tcl_Obj *) field
+	of the Interp struct, rather than using a global variable ::errorInfo
+	as the primary storage. The ERR_IN_PROGRESS flag bit value is no
+	longer required to manage the value in its new location, and is
+	removed. Variable traces are established to support compatibility for
+	any code expecting the ::errorInfo variable to hold the information.
+
+	***POTENTIAL INCOMPATIBILITY***
+	Code that sets traces on the ::errorInfo variable may notice a
+	difference in timing of the firing of those traces. Code that uses the
+	value ERR_IN_PROGRESS.

+
+	TIP#217 IMPLEMENTATION
+
+	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Add -indices option from James

+
+	* generic/tclUtil.c (TclMatchIsTrivial): Detect degenerate cases of
+	glob matching that let us avoid scanning through hash tables.
+	* generic/tclCmdIL.c (InfoCommandsCmd, InfoGlobalsCmd, InfoProcsCmd):

+
+	TIP#201 AND TIP#212 IMPLEMENTATIONS
+

+	* tests/expr.test: Basic tests of 'in' and 'ni' behaviour.
+	* tests/dict.test (dict-21.*,dict-22.*): Tests for [dict update] and
+	[dict with].
+	* generic/tclExecute.c (TclExecuteByteCode): Implementation of the

+	* generic/tclParseExpr.c (GetLexeme): Parse the 'in' and 'ni'
+	operators for TIP#201.
+	* generic/tclDictObj.c (DictUpdateCmd,DictWithCmd): Core of

+
+2004-10-07  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclTest.c (TestsetobjerrorcodeCmd):  Simplified.

+	* generic/tclPathObj.c:
+	* unix/tclUnixFile.c:
+	* win/tclWinFile.c:
+	* tests/fileName.test:
+	* tests/winFCmd.test: code reorganization for better generic/platform
+	code splitting [Bug 925620] removing the need for several #ifdef's,
+	and tests and fix for an unreported Windows glob problem ('glob -dir
+	C: -tails *').
+
+2004-10-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* *.3: Convert CONST to const and VOID to void so we document how
+	people should actually use the Tcl API and not the compatability hacks
+	that it has to have.
+
+	* doc/man.macros, *.3: Update .AS macro so it can know how wide to
+	make the third column of the argument list. Update documentation for C
+	API (only users) to take advantage of this.
+
+	* doc/FileSystem.3: Formatting fixes for greater documentation
+	clarity.
+
+2004-10-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclFileName.c (DoGlob, TclGlob): Stop messy sharing of
+	interpreter result and instead use a private object for collecting the
+	result of the glob. This simplifies TclGlob quite a lot.
+	* generic/tclIOUtil.c (Tcl_FSMatchInDirectory): Simplify by removing
+	some nesting. Also standardize variable names.
+	(FsAddMountsToGlobResult): Force updates to the list to be done
+	in-place, putting a side-condition of non-shared-ness on the resultPtr
+	argument to Tcl_FSMatchInDirectory, but everything would have broken
+	before if that was shared *anyway*.
+
+	* generic/tclEncoding.c (LoadTableEncoding): Removed reference to Tcl
+	interpreter; it wasn't needed as direct object use is more efficient.
+
+	* generic/tclPathObj.c: Made this file follow the style rules in the
+	Engineering Manual more closely, and also take advantage of the
+	internal object manipulation macros more.
+
+	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Reorganized to have fewer
+	magic flag variables and to separate the code that scans for a match
+	from the code that processes a match body.

+
+2004-10-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/SetResult.3: Made Tcl_AppendResult non-deprecated; better that

+	* generic/tclResult.c (Tcl_AppendResultVA): Make this work better with

+	avoid C++ keywords.
+
+2004-10-05  Don Porter	<dgp@users.sourceforge.net>

+	of the Interp struct, rather than using a global variable ::errorCode
+	as the primary storage. The ERROR_CODE_SET flag bit value is no longer

+
+2004-10-04  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tests/clock.test (clock-34.*): Removed an antibug that forced
+	comparison of [clock scan] results with the :localtime time zone. Now
+	that [clock scan] uses the current time zone instead, the antibug
+	caused several tests to fail. [Bug 1038554]
+
+2004-10-04  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclParseExpr.c (GetLexeme): Ensure that the 'eq' and 'ne'
+	operators are followed by non-alphabetic characters so lexemes can't
+	run together. [Bug 884830]
+
+	* doc/DictObj.3, doc/dict.n: Clarified that a dictionary is not

+2004-10-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

+	everyone seems to actually expect of the API! [Bug 1037235]
+	(Tcl_DictObjNext): Make calling this after Tcl_DictObjDone non-fatal

+
+	* generic/tclBasic.c (Tcl_EvalObjEx):	Removed the flag bit value

+	* tests/error.test (error-6.4-9):
+
+	* generic/tclNamespace.c (TclTeardownNamespace): Tcl_Obj-ified
+	* tests/namespace.test (namespace-8.5,6):	 the save/restore of
+	::errorInfo and ::errorCode during global namespace teardown. Revised
+	the comment to clarify why this is done, and added tests that will

+
+	* generic/tclResult.c (TclTransferResult): Added safety checks so that

+	Continued refactoring of [clock] for TIP 173 changes. Broke the
+	free-form parser apart so that the Bison parser is responsible for
+	only parsing, while clock.tcl handles relative times like "next
+	Thursday", "next January". This change is needed to make timezones
+	other than :localtime and :Etc/UTC work with free-form scanning. This
+	change closes out the issue identified as being "for another day" in
+	my log message of 2004-09-08. The refactored code also eliminates the
+	last known references to TclpStrftime and TclGetDate, so those
+	routines (including compat/strftime.c) have been removed. The
+	refactoring also has the benefit that all storage in the Bison parser
+	is now on the C stack, eliminating any need for mutex protection
+	around [clock scan]. Also, changed the Makefiles so that 'make
+	gendate' is available on Windows as well as Unix.
+
+	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Removed some grubby

+	different places in the code that need to know details about an

+2004-09-17  Kevin B.Kenny  <kennykb@acm.org>

+2004-09-14  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclClock.c (ClockOldscanObjCmd): Silenced a compiler warning
+	(long passed as a param where unsigend long was expected). 'Unsigned
+	long' is wrong, but the fix is really to change the signature of
+	TclGetDate to return a structure of its 'yy' variables and then do the
+	remaining work inside clock.tcl. But, as I said on 2004-09-08, that's
+	a job for another day. [Bug 1027993]

+2004-09-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclNamesp.c (NsEnsembleImplementationCmd): Add token field

+
+2004-09-11  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclClock.c (TclMktimeObjCmd): Corrected a bad check for

+	1026125].
+	* tests/clock.test (clock-43.1): Added regression test for error
+	return from 'mktime'.
+
+2004-09-11  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c (INST_CONCAT1): fix for [Bug 1025834]; avoid

+
+2004-09-10  David Gravereaux <davyrgvy@pobox.com>
+
+	* tests/tcltest.test: tcltest-12.3-4 needed to have

+
+2004-09-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclObj.c (SetIntOrWideFromAny): Rewritten integral value
+	parsing code so that values do not flip so easily between numeric
+	representations. Thanks to KBK for this! [Bug 868489]
+
+	* generic/tclIO.c (Tcl_Seek): Make sure wide seeks do not fail to set
+	::errorCode on error. [Bug 1025359]
+
+2004-09-10  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tcl.h: Micro formatting fixes.

+
+2004-09-11  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclNamespace.c (TclGetNamespaceForQualName): Resolved
+	longstanding inconsistency in the treatment of the TCL_NAMESPACE_ONLY
+	flag revealed by testing the 2004-09-09 commits against Itcl.
+	TCL_NAMESPACE_ONLY now acts as specified in the pre-function comment,
+	forcing resolution in the passed in context namespace. It has been
+	incorrectly forcing resolution in the interp's current namespace.
+
+2004-09-10  Kevin Kenny	 <kennykb@acm.org>
+
+	* library/clock.tcl: Fixed a bug where %z always put a plus sign on
+	the time zone in :localtime.
+	* tests/clock.test: Added test case for the above bug.
+
+2004-09-10  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c (INST_CONCAT1): added a peephole optimisation
+	for concatting an empty string. This enables replacing the idiom 'K $x
+	[set x {}]' by '$x[set x {}]' for fastest execution.
+
+2004-09-09  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinConsole.c: Calls to WriteFile and WriteConsoleA changed to
+	WriteConsole for simplicity.
+
+2004-09-09  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclNamesp.c (Tcl_ForgetImport):	Corrected faulty
+
+	* tests/namespace.test: logic that relied exclusively on string
+	matching and failed in the presence of [rename]s. [Bug 560297] Also
+	corrected faulty prevention of [namespace import] cycles. [Bug 1017299]
+
+2004-09-08  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (Tcl_CreateInterp):	Removed obsolete field
+	for storing the string-based command procedure of built-in commands.
+	We no longer have any string-based built-in commands!
+
+2004-09-08  Kevin B. Kenny <kennykb@acm.org>
+
+	* compat/strftime.c (_conv): Corrected a problem where hour 0 would
+	format as a blank format group with %k.
+	* doc/clock.n: Corrected a buglet in the header information. [Bug
+	1024058]
+	* generic/tclClock.c (TclClockMktimeObjCmd): Fixed a bug where the
+	month was scanned incorrectly in -timezone :localtime.
+	* tests/clock.test (clock-34.*,clock-40.1, clock-41.1): Adjusted the
+	clock-34.* test cases so that the consistency check is performed in
+	:localtime rather than the current time zone. This change allows
+	dealing with issues where the C library has a different idea of DST
+	conversion than Tcl. (Real fix would be to break TclGetDate into
+	separate parser and time converter, and do the time conversion in
+	clock.tcl. That's for another day.) Added regression test case for the
+	bug where month was scanned incorrectly in -timezone :localtime. [Bug
+	1023779] Added regression test case for %k at the zero hour.
+
+2004-09-07  David Gravereaux <davygrvy@pobox.com>
+
+	* win/makefile.vc: some quoting needed to be removed as it was
+	breaking with VC7. [Bug 1023150]
+
+2004-09-07  Kevin B. Kenny  <kennykb@acm.org>
+
+	* doc/clock.n: Documented the default -format, and changed references
+	to a (nonexistent) msgcat command to refer to the msgcat package. [Bug
+	1023870]
+	* generic/tclTimer.c: Removed a premature optimisation that attempted
+	to store the assoc data in the client data; the optimisation caused a
+	bug that [after] would overwrite its imports. [Bug 1016167]
+	* library/clock.tcl (InitTZData, ClearCaches): Changed so that the
+	in-memory time zone :UTC (and its aliases) always gets reinitialised,
+	in case tzdata is absent. [Bug 1019537, 1023779]
+	* library/tzdata/*: Regenerated.
+	* tests/clock.test (clock-31.*, clock-39.1): Corrected a problem where
+	the 'system' locale tests fail on a non-English Windows machine. [Bug
+	1023761]. Added a test to make sure that alias time zones load
+	correctly. [Bug 1023779].
+	* tests/timer.test (timer-1.1, timer-2.1): Changed to (one hopes!) be
+	more resilient on an overloaded system, if [after 200] sleeps for 300
+	ms or longer.
+	* tools/tclZIC.tcl (writeLinks): Corrected a problem where alias time
+	zone names were written incorrectly, causing them to fail to load at
+	run time. [Bug 1023779].
+	* win/tclWinTime.c (Tcl_GetTime): Eliminated CPUID tests on Win64 -
+	assuming that HAL vendors now do a better job of keeping the
+	performance counters synchronized among CPU's. [Bug 1020445]

+		Implementation of TIPs #173 and #209.
+
+	The [clock] command is now a Tcl ensemble, with most of its
+	functionality written in Tcl and callouts to C code only to access
+	low-level functions such as localtime, mktime and tzset.
+
+	In addition to the functionality changes called out in the two TIPs,
+	it is worth noting that the [clock] command in a safe slave
+	interpreter is now an alias to the [clock] command in the master, and
+	that [clock] is otherwise not expected to function entirely correctly
+	in safe interps. C code that simply does Tcl_MakeSafe needs to be
+	aware that [clock] may need special handling. (It appears unlikely
+	that such code actually exists.)
+
+	One incompatibility of note is that if the time zone cannot be
+	determined from the TZ, TCL_TZ environment variables, or from the
+	Windows control panel, so that the C library must be used for date and
+	time conversions, then times outside the range of time_t will fail;
+	they used to return bad data silently.
+
+	Many thanks to all the many people who assisted with testing,
+	debugging, criticism of the specification, and localisation. Deserving
+	of particular mention are Joe English, Clif Flynt, Donal K. Fellows,
+	Jeff Hobbs, Cameron Laird, Arjen Markus, Reinhard Max, Christopher
+	Nelson, Steve Offutt, Donald G. Porter, Pascal Scheffers, Peter da
+	Silva and Richard Suchenwirth-Bauersachs.

+2004-07-14  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c:
+	* generic/tclIO.h:
+	* Not reverting, but #ifdef'ing the changes from May 19, 2004 out of
+	the core. This removes the ***POTENTIAL INCOMPATIBILITY*** for channel
+	drivers it introduced. This has become possible due to Expect gaining
+	a BlockModeProc and now handling blockingg and non-blocking modes
+	correctly. Thus [SF Tcl Bug 943274] is still fixed if a recent enough
+	version of Expect is used.
+
+	* doc/CrtChannel.3: Added warning about usage of a channel without a
+	BlockModeProc.
+
+2004-07-15  Andreas Kupries  <andreask@pliers.activestate.com>
+
+	* generic/tclIOCmd.c (Tcl_PutsObjCmd): Added length check to the old

+	<mistachkin@users.sourceforge.net>.
+
+2004-07-15  Zoran Vasiljevic <vasiljevic@users.sf.net>
+
+	* generic/tclEvent.c (Tcl_Finalize): stuffed memory leak incurred by
+	re-initializing of TSD slots after the last call to
+	TclFinalizeThreadData (done from within Tcl_FinalizeThread()). We
+	basically just repeat the TclFinalizeThreadData() once more before
+	tearing down TSD keys in TclFinalizeSynchronization(). There should be
+	more elaborate mechanism in place for handling such issues, based on
+	thread cleanup handlers registered on the OS level. Such change
+	requires much more work and would also require TIP because some
+	visible parts of Tcl API would have to be modified. In the meantime,
+	this will do.
+
+	* generic/tclNotify.c (TclFinalizeNotifier): Added conditional
+	notifier finalization based on the fact that an TclInitNotifier has
+	been called for the current thread. This fixes the [Bug 770053] again.
+	Hopefully this time w/o unwanted side-effects.
+
+2004-07-15  Kevin Kenny	 <kennykb@acm.org>
+
+	* generic/tclLiteral.c (TclReleaseLiteral): Removed unused variable

+
+	* generic/tclCompile.c (TclCompileScript):
+	* generic/tclLiteral.c (TclReleaseLiteral): fix for [Bug 467523],
+	which resurfaced with the latest changes. The previous strategy was to
+	have special code in TclReleaseLiteral to handle the self-references
+	generated by empty scripts. The new approach avoids the self-reference

+
+	* tests/clock.test (clock-2.11): Changed the test so that it isn't an

+
+2004-07-08  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclBasic.c (DeleteInterpProc): reverted the modification of

+	* generic/tclCompile.c (TclCleanupByteCode): let each bytecode remove
+	its references to literals at interp deletion, without updating the
+	dying literal table.
+	* generic/tclLiteral.c (TclDeleteLiteralTable): with the above change
+	to TclCleanupByteCode, this function now removes a single reference to

+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): that can be tested for with
+	the [string is] subcommand. [Patch 940915, by Kevin Kenny]
+
+2004-06-29  Don Porter	<dgp@users.sourceforge.net>
+
+	* win/tclWinInit.c:	Corrected reference counting flaw in recent
+	changes. Thanks to Pat Thoyts. [Bug 981893].
+
+2004-06-29  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* win/tclWin32Dll.c: fix to compilation with VC++ 5.2
+
+2004-06-29  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* library/safe.tcl: Make sure that the temporary variable is local to
+	the namespace and not inadvertently global. [Bug 981733]
+
+2004-06-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* tests/unixNotfy.test: Modified constraints so that testing with a
+	threaded tclsh (not tcltest) will not hang.
+
+2004-06-23  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclThreadStorage.c: Corrected type casting errors that led
+	to calculation of a negative index value, thus accesses outside the
+	threadStorageCache array, thus memory corruption. Crash observed on
+	Mac OS X platform.
+
+2004-06-23  Joe Mistachkin  <joe@mistachkin.com>
+
+	* generic/tclThread.c: Implements platform independent thread storage
+	* generic/tclThreadStorage.c: mechanism and fixes associated bugs on
+	platforms where there is limited thread local storage space
+	(Win98/WinNT4). [Patch 976496]
+
+	* generic/tclInt.decls:
+	* generic/tclIntDecls.h: Added thread storage functions to the
+	* generic/tclStubInit.c: internal stubs table.
+
+	* unix/Makefile.in:
+	* unix/configure:
+	* unix/tcl.m4:
+	* win/makefile.vc:
+	* win/rules.vc:
+	* win/Makefile.in: Modified the unix, VC++, and Cygwin build systems
+	* win/configure: to include the new "tclThreadStorage.c" and the new
+	* win/tcl.m4: USE_THREAD_STORAGE define.
+
+2004-06-23  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* tests/io.test: Added -force to 18.1 and 18.2. This was failing on
+	WinXP.
+
+	* tests/winFCmd.test: Added a cleanup to winFCmd-16.11 to avoid a
+	failure in 16.12.
+
+	* tests/eofchar.data: Added -kb option to ensure a binary checkout to
+	win32 systems. This fixes a failure in io-61.1
+
+	* win/makefile.vc: fix for [Bug 977369] about launching tclsh to
+	generate a tclConfig.sh with the nmake build system
+
+2004-06-23  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tests/winDde.test (createChildProcess): Added a 200-ms delay (with
+	the event loop live) when shutting down the test DDE server process.
+	With the delay in place, nuisance failures of tests winDde-4.2, -6.5,
+	and -6.6 appear to be much less frequent. [Bug 957449]
+
+2004-06-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* tests/*.test: Standardize use of platform constraints.
+
+	* unix/tclUnixInit.c (GetStackSize, TclpCheckStackSpace):
+	* unix/tclUnixThrd.c (TclpThreadGetStackSize): Added code to check
+	whether the C stack is about to be exceeded, from [Patch 746378] by
+	Joe Mistachkin but with substantial revisions.
+
+2004-06-22  Kevin Kenny	 <kennykb@acm.org>
+
+	* generic/tclEvent.c (NewThreadProc): Fixed broken build on Windows
+	caused by missing TCL_THREAD_CREATE_RETURN.
+
+	* tests/stack.test (stack-3.1): Corrected nuisance error in threaded
+	builds.
+
+2004-06-22  Zoran Vasiljevic <vasiljevic@users.sf.net>
+
+	* generic/tclEvent.c:
+	* generic/tclInt.h:
+	* unix/tclUnixNotfy.c:
+	* unix/tclUnixThrd.c:
+	* win/tclWinThrd.c: [Bug 770053]. See bug report for more information
+	about what it does.
+
+	* tests/unixNotfy.test: rewritten to use tcltest::threadReap to
+	gracefully wait for the test thread to exit. Otherwise we got a race
+	condition with main thread exiting before the test thread. This
+	exposed the long-standing Tcl lib issue with resource
+	garbage-collection on application exit.
+
+2004-06-21  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/tclWin32Dll.c (DllMain, _except_dllmain_detach_handler)
+	(TclpCheckStackSpace, _except_checkstackspace_handler)
+	(TclWinCPUID, _except_TclWinCPUID_detach_handler):

+	(_except_makefilechannel_handler):
+	* win/tclWinFCmd.c (DoRenameFile, _except_dorenamefile_handler)
+	(DoCopyFile, _except_docopyfile_handler):
+	Rework pushing of exception handler function pointer so that compiling
+	with gcc -O3 works. Remove empty function call to avoid compiler
+	warning. Mark the DllMain function as noinline to avoid compiler error
+	from duplicated asm labels in generated code.
+
+2004-06-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclThreadAlloc.c (Ptr2Block): Rewrote so as to maximize the
+	chance of detecting and reporting a memory inconsistency without
+	relying on things being consistent. [Bug 975895]
+
+2004-06-18  Don Porter	<dgp@users.sourceforge.net>
+
+	* tests/load.test:	Relaxed strictness of error message matching
+	for test load-2.3 so that it will pass on Mac OSX.
+
+	* generic/tclEncoding.c: Static TclFindEncodings -> FindEncodings.
+	* generic/tclInt.h:	Updated TclpFindExecutable() so that failed
+	* generic/tclUtil.c:	attempts to find the executable are saved
+	* unix/tclUnixFile.c:	just as successful finds are. [Patch 966053]
+	* unix/tclUnixTest.c:
+
+2004-06-18  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tests/winFCmd.test (winFCmd-16.12): Changed test to compute the
+	target directory, so as not to fail if the user's HOME isn't the root.
+
+2004-06-19  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tcl.m4: autoconf 2.5 fixes in Darwin section.
+	* unix/configure: autoconf-2.57
+
+2004-06-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* unix/tclUnixInit.c (localeTable): Added some more locale to encoding
+	mapping info from Jim Huang <jserv@kaffe.org>
+
+	* generic/tclInt.h (PendingObjData,TclFreeObjMacro,etc):
+	* generic/tclObj.c (TclFreeObj): Added scheme for making TclFreeObj()
+	avoid blowing up the C stack when freeing up very large object trees.
+	[Bug 886231]
+
+	* win/tclWinInit.c (SetDefaultLibraryDir): Fix logic, simplify and add
+	comments.
+
+2004-06-17  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclObj.c:	Added missing space in panic message.
+
+	* win/tclWinInit.c:	Inform [tclInit] about the default library
+	directory via the ::tclDefaultLibrary variable. This should correct a
+	problem with my 2004-06-11 commit. Better solutions still in the
+	works. Thanks to Joe Mistachkin for pointing out the breakage.
+
+2004-06-16  Don Porter	<dgp@users.sourceforge.net>
+
+	* doc/library.n:	Moved variables ::auto_oldpath and
+	* library/auto.tcl:	::unknown_pending into ::tcl namespace.
+	* library/init.tcl:	[Bugs 808319, 948794]
+
+2004-06-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/binary.n: Added some notes to the documentation of the 'a'
+	format to address the point raised in [RFE 768852].
+
+2004-06-15  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* unix/tclConfig.sh.in (TCL_EXTRA_CFLAGS): set to @CFLAGS@, which is
+	the configure-time CFLAGS. Addendum to m4 change on 2004-05-26.
+
+2004-06-14  Kevin Kenny	 <kennykb@acm.org>
+
+	* win/Makefile.in: Corrected compilation flags for tclPkgConfig.c so
+	that it doesn't require Stubs.
+	* generic/tclBasic.c (Tcl_CreateInterp): Removed comment stating that
+	TclInitEmbeddedConfigurationInformation needs Stubs; with the change
+	above, the comment is now erroneous.
+
+2004-06-11  Don Porter	<dgp@users.sourceforge.net>
+
+	* doc/Encoding.3:	Removed bogus claims about tcl_libPath.
+
+	* generic/tclInterp.c (Tcl_Init):	Stopped setting the
+	tcl_libPath variable. [tclInit] can get all its directories without it.
+
+	* tests/unixInit.test:	Modified test code that made use of
+	tcl_libPath variable.
+
+	* unix/tclUnixInit.c:	Stopped setting the tclDefaultLibrary variable,
+	execept on the Mac OS X platform with HAVE_CFBUNDLE. In that
+	configuration we should seek some way to make use of the TIP 59
+	facilities and get rid of that usage of tclDefaultLibrary as well.
+
+	* generic/tclInterp.c:	Updated [tclInit] to make $env(TCL_LIBRARY) an
+	absolute path, and to include the scriptdir,runtime configuration value
+	on the search path for init.tcl.
+
+	* unix/tclUnixInit.c:	The routines Tcl_Init() and TclSourceRCFile()
+	* win/tclWinInit.c:	had identical implementations for both win and
+	* generic/tclInterp.c:	unix. Moved to a single generic implementation.
+	* generic/tclMain.c:
+	* library/init.tcl:
+	* generic/tclInitScript.h (removed):
+	* unix/Makefile.in:
+	* win/tcl.dsp:
+
+	* unix/configure.in:	Updated TCL_PACKAGE_PATH value to handle
+	* win/configure.in:	--libdir configuration.
+
+	* unix/configure.in:	autoconf-2.57
+	* win/configure.in:
+
+	* generic/tclBasic.c (Tcl_CreateInterp): Moved call to
+	TclInitEmbeddedConfigurationInformation() earlier in
+	Tcl_CreateInterp() so that other parts of interp creation and
+	initialization may access and use the config values.
+
+2004-06-11  Kevin Kenny	 <kennykb@acm.org>
+
+	* win/tclAppInit.c: Restored the 'setargv' procedure when compiling
+	with mingw. Apparently, the command line parsing in mingw doesn't work
+	as well as that in vc++, and the result was (1) that winPipe-8.19
+	failed, and (2) that 'make test' would work at all only with
+	TESTFLAGS='-singleproc 1'. [Bug 967195]
+
+2004-06-10  Zoran Vasiljevic <vasiljevic@users.sf.net>
+
+	* generic/tclIOUtil.c: removed forceful setting of the private cached
+	current working directory rep from within the Tcl_FSChdir(). We
+	delegate this task to the Tcl_FSGetCwd() which does this task anyway.
+	The relevant code is still present but disabled temporarily until the
+	change proves correct. The Tcl test suite passes all test with the
+	given change so I suppose it is good enough.
+
+2004-06-10  Don Porter	<dgp@users.sourceforge.net>
+
+	* unix/tclUnixInit.c (TclpInitLibraryPath):	Disabled addition of
+	* win/tclWinInit.c (TclpInitLibraryPath):	relative-to-executable
+	directories to the library search path. A first step in reform of
+	Tcl's startup process.
+
+	***POTENTIAL INCOMPATIBILITY***
+	Attempts to directly run ./tclsh or ./tcltest out of a build directory
+	will either fail, or will make use of an installed script library in
+	preference to the one in the source tree. Use `make shell` or `make
+	runtest` instead.
+
+	* tests/unixInit.test:	Modified tests to suit above changes.
+
+	* generic/tclPathObj.c:	Corrected [file tail] results when operating
+	on a path produced by TclNewFSPathObj(). [Bug 970529]
+
+2004-06-09  Zoran Vasiljevic <vasiljevic@users.sf.net>
+
+	* generic/tclIOUtil.c: partially corrected [Bug 932314]. Also
+	corrected return values of Tcl_FSChdir() to reflect those of the
+	underlying platform-specific call. Originally, return codes were mixed
+	with those of Tcl.
+
+2004-06-08  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCompile.c:
+	* generic/tclExecute.c: handle warning [Bug 969066]
+
+2004-06-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclHash.c (RebuildTable): Move declaration of variable so it

+
+2004-06-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/lsearch.n: Added correct option to example. [Bug 968219]
+
+2004-06-05  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tcl.h: Corrected Tcl_WideInt declarations so that the mingw
+	build works again.
+	* generic/tclDecls.h:			Changes to the tests for clock
+	* generic/tclInt.decls:			frequency in Tcl_WinTime so
+	* generic/tclIntDecls.h:		that any clock frequency is
+	* generic/tclIntPlatDecls.h:		accepted provided that all
+	* generic/tclPlatDecls.h:		CPU's in the system share a
+	* generic/tclStubInit.c:		common chip, and hence,
+	* tests/platform.test (platform-1.3):	presumably, a common clock.
+	* win/tclWin32Dll.c (TclWinCPUID):	This change necessitated a
+	* win/tclWinTest.c (TestwincpuidCmd)	small burst of assembly code
+	* win/tclWinTime.c (Tcl_GetTime):	to read CPU ID information,
+	which was added as TclWinCPUID in the internal Stubs. To test this
+	code in the common case of a single-processor machine, a
+	'testwincpuid' command was added to tclWinTest.c, and a test case in
+	platform.test. Thanks to Jeff Godfrey and Richard Suchenwirth for
+	reporting this bug. [Bug 976722]
+
+2004-06-04  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tcl.h:	Restored #include <stdio.h> to tcl.h,
+	rejecting the "fix" for "Bug" 945570. Tcl_FSSeek() needs the values of
+	SEEK_SET, etc. and too many extensions rely on tcl.h providing stdio.h
+	for them.
+
+2004-06-02  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* win/tclWinFile.c (TclpFindExecutable): when using GetModuleFileNameA
+	(Win9x), convert from CP_ACP to WCHAR then convert back to utf8.
+	Adjunct to 2004-04-07 fix.
+
+2004-06-02  David Gravereaux <davygrvy@pobox.com>
+
+	* tests/winPipe.test (winpipe-6.1): blocking set to 1 before closing
+	to ensure we get an exitcode. The windows pipe channel driver doesn't
+	differentiate between a blocking and non-blocking close just yet, but
+	will soon. Part of [Bug 947693]
+
+2004-06-02  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* doc/file.n: fix to documentation of 'file volumes' (Bug 962435)
+
+2004-06-01  David Gravereaux <davygrvy@pobox.com>
+
+	* win/makefile.vc: check for either MSDEVDIR or MSVCDIR being in the
+	environment, for VC7. [Bug 942214]
+
+	* generic/tclIO.c (Tcl_SetChannelOption): -buffersize wasn't
+	understanding hexidecimal notation nor was reporting number conversion
+	errors. The behavior to silently ignore settings outside the
+	acceptable range of Tcl_SetChannelBufferSize (<10 or >1M) is
+	unchanged. This silent ignoring behavior might be up for review soon.
+
+2004-05-30  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinPipe.c:
+	* win/tclWinPort.h:  Reworked the win implementation of Tcl_WaitPid to
+	support exitcodes in the 'signed short' range. Even though this range
+	is non-portable, it is valid on windows. Detection of exception codes
+	are now more accurate. Previously, an application that exited with
+	ExitProcess((DWORD)-1); was improperly reported as exiting with
+	SIGABRT.
+
+2004-05-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclInterp.c: Added comments describing the purposes of each
+	function in the limit implementation and rewrote the names of some
+	non-public functions for greater clarity of purpose.
+	* doc/interp.n: Added note about what happens when a limited
+	interpreter creates a slave interpreter.
+	* doc/Limit.3: Added manual page for the resource limit subsystem's C
+	API. [Bug 953903]
+
+2004-05-29  Joe English	 <jenglish@users.sourceforge.net>
+
+	* doc/global.n, doc/interp.n, doc/lrange.n: Fix minor markup errors.
+
+2004-05-28  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/*.n: Added examples to many (too many to list) more man pages.
+
+2004-05-25  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c:
+	* generic/tclVar.c: using (ptrdiff_t) instead of (int) casting to
+	correct compiler warnings [Bug 961657], reported by Bob Techentin.
+
+2004-05-27  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tests/clock.test: Added a single test for the presence of %G in
+	[clock format], and conditioned out the clock-10.x series if they're
+	all going to fail because of a broken strftime() call. [Bug 961714]
+
+2004-05-27  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclHash.c (CompareStringKeys): Added #ifdef to allow people
+	to instruct this function to use strcmp(). [FRQ 951168]
+
+	* generic/tclVar.c: Moved declarations into #if guards so they only
+	happen when required.
+	* unix/tclUnixPort.h: Guard declaration of strtod() so it is only
+	enabled when we don't have a declaration in stdlib.h
+	* unix/tclUnixThrd.c (Tcl_CreateThread):	Added declarations
+	* unix/tclUnixTest.c (AlarmHandler):		and casts so that
+	* unix/tclUnixChan.c (TtyModemStatusStr):	all functions are
+	* generic/tclScan.c (Tcl_ScanObjCmd):		defined before use
+	* generic/tclDictObj.c (InvalidateDictChain):	and no cross-type
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd):	uses are performed.
+
+	The overall effect is to make building with gcc with the additional
+	flags -Wstrict-prototypes -Wmissing-prototypes produce no increase in
+	the total number of warnings (except for main(), which is undeclared
+	for traditional reasons.)
+
+2004-05-26  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* unix/Makefile.in:  Rework configure ordering to TCL_LINK_LIBS,
+	* unix/tcl.m4:	     ENABLE_SHARED, CONFIG_CFLAGS, & ENABLE_SYMBOLS
+	* unix/configure:    before TCL_EARLY_FLAGS and TCL_64BIT_FLAGS
+	* unix/configure.in: (about 400 lines earlier) in configure.in. This
+	forces CFLAGS configuration to be done before many tests, which is
+	needed for 64-bit builds and may affect other builds. Also make
+	CONFIG_CFLAGS append to CFLAGS directly instead of using EXTRA_CFLAGS,
+	and have LDFLAGS append to any existing value. [Bug 874058]
+	* unix/dltest/Makefile.in: change EXTRA_CFLAGS to DEFS
+
+2004-05-26  Don Porter	<dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl:	Correction to debug prints and testing
+	* library/tcltest/pkgIndex.tcl:	if TCLTEST_OPTIONS value. Corrected
+	* tests/tcltest.test:		double increment of numTestFiles in
+	-singleproc 1 configurations. Updated tcltest-19.1 to tcltest 2.1
+	behavior. Corrected tcltest-25.3 to not falsely report a failure in
+	tcltest.test. Bumped to tcltest 2.2.6. [Bugs 960560, 960926]
+
+2004-05-25  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* doc/http.n (http::config): add -urlencoding option (default utf-8)
+	* library/http/http.tcl:     that specifies encoding conversion of
+	* library/http/pkgIndex.tcl: args for http::formatQuery. Previously
+	* tests/http.test:	     undefined, RFC 2718 says it should be
+	utf-8. 'http::config -urlencoding {}' returns previous behavior, which
+	will throw errors processing non-latin-1 chars. Bumped http package to
+	2.5.0.
+
+2004-05-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclInterp.c (DeleteScriptLimitCallback): Move all deletion
+	of script callback hash table entries to happen here so the entries
+	are correctly removed at the right time. [Bug 960410]
+
+2004-05-25  Miguel Sofer <msofer@users.sf.net>
+
+	* docs/global.n: added details for qualified variable names [Bug
+	959831]
+
+2004-05-25  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclNamesp.c (Tcl_FindNamespaceVar):
+	* tests/namespace.test (namespace-17.10-12): reverted commit of
+	2004-05-23 and removed the tests, as it interferes with the varname
+	resolver and there are apps that break (AlphaTk). A fix will have to
+	wait for Tcl9.
+
+	* generic/tclVar.c: Caching of namespace variables disabled: no simple
+	way was found to avoid interfering with the resolver's idea of
+	variable existence. A cached varName may keep a variable's name in the
+	namespace's hash table, which is the resolver's criterion for
+	existence.
+
+	* tests/namespace.c (namespace-17.10): testing for interference
+	between varname caching and name resolver.
+
+2004-05-25  Kevin Kenny	 <kennykb@acm.org>
+
+	* tests/winFCmd.test: Correct test for the presence of a CD-ROM so
+	that it doesn't misdetect some other sort of filesystem with a
+	write-protected root as being a CD-ROM drive. [Bug 918267]
+
+2004-05-25  Don Porter	<dgp@users.sourceforge.net>
+
+	* tests/winPipe.test:	Protect against path being set
+	* tests/unixInit.test:	Unset path when done.
+	* tests/unload.test (unload-3.1): Verify [pkgb_sub] does not exist.
+	Delete interps when done.
+	* tests/stringComp.test:	stop re-use of string.test test names
+	* tests/regexpComp.test:	stop re-use of regexp.test test names

+	* tests/http.test:	Clear away the custom [bgerror] when done.
+	* tests/io.test:	Take care to use namespace variables.
+	* tests/autoMkindex.test (autoMkindex-5.2): Use variable "result"
+	that gets cleaned up.
+	* tests/exec.test:	Clean up the "path" array.
+	* tests/interp.test (interp-9.3): Initialize res, so prior values
+	cannot make the test fail.
+	* tests/execute.test (execute-8.1):  Updated to remove the trace set
+	on ::errorInfo. When left in place, that trace can cause later tests
+	to fail.
+
+2004-05-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclBasic.c: Removed references to Tcl_RenameCommand from
+	* generic/tcl.h:      comments. [Bug 848440, second part]
+
+	* tests/fCmd.test: Rewrote tests that failed consistently on NFS so
+	they either succeed (through slightly more liberal matching of the
+	results) or are constrained to not run. [Bug 931312]
+
+	* doc/bgerror.n: Use idiomatic open flags for working with log
+	files. [Bug 959602]
+
+2004-05-24  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* generic/tclExecute.c (VerifyExprObjType): use GET_WIDE_OR_INT to
+	properly have tclIntType used for smaller values. This corrects [TclX
+	Bug 896727] and any other 3rd party extension that created math
+	functions but was not yet WIDE_INT aware in them.
+
+2004-05-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclInterp.c (TclInitLimitSupport): Made limits work on
+	platforms where sizeof(void*)!=sizeof(int). [Bug 959193]
+
+2004-05-24 Miguel Sofer <msofer@users.sf.net>
+
+	* doc/set.n: accurate description of name resolution process,
+	referring to namespace.n for details [Bug 959180]
+
+2004-05-23  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclNamesp.c (Tcl_FindNamespaceVar): [Bug 959052] fixed,
+	insuring that no "zombie" variables are found.
+	* generic/tclVar.c (TclLookupSimpleVar): comments re [Bug 736729]
+	(predecessor of [Bug 959052]) removed.
+	* tests/namespace.test: added tests 17.10-12
+
+	The patch modifies non-documented behaviour, and passes every test in
+	the testsuite. However, scripts relying on the old behaviour may
+	break.
+	Note that the only behaviour change concerns the creative writing of
+	unset variables. More precisely, which variable will be created when
+	neither a namespace variable nor a global variable by that name
+	exists, as defined by [info vars]. The new behaviour is that the
+	namespace resolution process deems a variable to exist exactly when
+	[info vars] finds it - ie, either it has value, or else it was "fixed"
+	by a call to [variable].
+	Note: this patch was removed on 2002-05-25.
+
+2004-05-22  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclVar.c (TclObjLookupVar, TclObjUnsetVar2): fix for new (in
+	tcl8.4) exteriorisations of [Bug 736729] due to the use of
+	tclNsVarNameType obj types. Reenabling the use of this objType ("VAR
+	ref absolute" benchmark down to 66 ms, from 230). Added comments in
+	TclLookupSimpleVar explaining my current understanding of [Bug
+	736729].
+
+2004-05-22  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclVar.c: fix for [Bug 735335]. The use of tclNsVarNameType
+	objs is still disabled, pending resolution of [Bug 736729].
+
+2004-05-21  Miguel Sofer <msofer@users.sf.net>
+
+	* tests/namespace.test (namespace-41.3): removed the {knownBug}
+	constraint: [Bug 231259] is closed since nov 2001, and the fix of [Bug
+	729692] (INST_START_CMD) makes the test succeed.
+
+2004-05-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclExecute.c (TclExecuteByteCode): Move a few declarations a
+	short distance so pre-C99 compilers can cope. Also fix so
+	TCL_COMPILE_DEBUG path compiles...
+
+2004-05-21  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c (TclExecuteByteCode): reorganised TEBC
+	automatic variables, defining them in tight blocks instead of at the
+	function level. This has three purposes:
+	- it simplifies the analysis of individual instructions
+	- it is preliminary work to the non-recursive engine
+	- it allows a better register allocation by the optimiser; under
+	gcc3.3, this results in up to 10% runtime in some tests
+
+2004-05-20  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclInterp.c (TclLimitRemoveAllHandlers):
+	* generic/tclBasic.c (DeleteInterpProc):
+	* tests/interp.test (interp-34.7): Ensure that all limit callbacks are
+	deleted when their interpreters are deleted. [Bug 956083]
+
+2004-05-19  Kevin B. Kenny  <kennykb@acm.org>
+
+	* win/tclWinFile.c (TclpMatchInDirectory): fix for an issue where
+	there was a sneak path from Tcl_DStringFree to SetErrorCode(0). The
+	result was that the error code could be reset between a call to
+	FindFirstFileEx and the check of its status return, leading to a
+	bizarre error return of {POSIX unknown {No error}}. (Found in
+	unplanned test - no incident logged at SourceForge.)
+
+2004-05-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* tests/interp.test (interp-34.3): Rewrite this test to see if a time
+	limit can catch a tight bytecode loop, a maximally aggressive
+	denial-of-service attack.
+	* generic/tclInterp.c (Tcl_LimitCheck): Fix the sense of checks to see
+	whether a time limit has been extended.
+
+	* tests/*.test: Many minor fixes, including ensuring that every test
+	is run (so constraints control whether the test is doing anything) and
+	making sure that constraints are always set using the API instead of
+	poking around inside tcltest's internal datastructures. Also got rid
+	of all trailing whitespace lines from the test suite!
+
+2004-05-19  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c: Fixed [SF Tcl Bug 943274]. This is the same problem
+	* generic/tclIO.h: as [SF Tcl Bug 462317], see ChangeLog entry
+	2001-09-26. The fix done at that time is incomplete. It is possible to
+	get around it if the actual read operation is defered and not executed
+	in the event handler itself. Instead of tracking if we are in an read
+	caused by a synthesized fileevent we now track if the OS has delivered
+	a true event = actual data and bypass the driver if a read finds that
+	there is no actual data waiting. The flag is cleared by a short or
+	full read.
+
+	***POTENTIAL INCOMPATIBILITY*** for channel drivers.
+
+2004-05-17  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclPathObj.c: fix to (Bug 956063) in 'file dirname'.
+	* tests/cmdAH.test: added test for this bug.
+
+	* doc/FileSystem.3: better documentation of refCount requirements of
+	some FS functions (Bug 956126)
+
+2004-05-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclTest.c (TestgetintCmd): Made the tests in get.test check
+	* tests/get.test:		     Tcl_GetInt() since the core now
+					     avoids that function.
+
+2004-05-18  Kevin B. Kenny  <kennykb@acm.org>
+
+	* compat/strftime.c (_fmt, ISO8601Week):
+	* doc/clock.n:
+	* tests/clock.test: Major rework to the handling of ISO8601 week
+	numbers. Now passes all the %G and %V test cases on Windows, Linux and
+	Solaris [Bugs 500285, 500389, and 852944]
+
+2004-05-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/append.n, doc/upvar.n: Added example.
+
+2004-05-18  David Gravereaux <davygrvy@pobox.com>
+
+	* win/makefile.vc: now generates a tclConfig.sh from Pat Thoyts [Patch
+	909911]
+
+2004-05-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/lsearch.n: Improve clarity (based on [Patch 955361] by Peter
+	Spjuth)
+
+	* tools/man2help2.tcl (macro,SHmacro): Added support for subsection
+	(.SS) header macros.
+
+	* doc/interp.n: Added user documentation for the TIP#143 resource
+	limits and some examples.
+
+	* generic/tclInterp.c (Tcl_LimitCheck, Tcl_LimitTypeReset): Reset the
+	limit-exceeded flag when removing a limit.
+
+2004-05-18  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c (TclExecuteByteCode): added comments to
+	classify the variables according to their use in TEBC.
+
+2004-05-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/global.n, doc/uplevel.n: Added an example.
+
+	* tests/info.test (info-3.1): Corrected test result back to what it
+	used to be in Tcl 7.* now that command counts are being correctly kept
+
+	* generic/tclExecute.c (TEBC:INST_START_CMD): Make sure that the
+	command-count is always advanced. Allows TIP#143 limits to tell that
+	work is being done.
+
+	* doc/list.n: Updated example to fit with the unified format.
+	* doc/seek.n: Added some examples.
+
+2004-05-17  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* win/tclWinFile.c:
+	* tests/cmdAH.test: fix to (Bug 954263) where 'file executable' was
+	case-sensitive.
+
+2004-05-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/OpenFileChnl.3: Documented type of 'offset' argument to Tcl_Seek
+	was wrong. [Bug 953374]
+
+2004-05-16  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c (TclExecuteByteCode): remove one level of
+	indirection for compiledLocals addressing.
+
+2004-05-16  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c (INST_CALL_FUNC1): bugfix; restored
+	(DE)CACHE_STACK_INFO pair around the call - the user defined math
+	function could cause a recursive call to TEBC.
+
+2004-05-16  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclBasic.c (Tcl_DeleteInterp):
+	* generic/tclExecute.c (INST_START_CMD): interp deletion now modifies
+	the compileEpoch, eliminating the need for the check for interp
+	deletion in INST_START_CMD.
+
+2004-05-16  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCompile.h:
+	* generic/tclCompile.c:
+	* generic/tclExecute.c: changed implementation of {expand}, last
+	chance while in alpha as ...
+
+	***POTENTIAL INCOMPATIBILITY***
+	Scripts precompiled with ProComp under previous tcl8.5a versions may
+	malfunction due to changed instruction numbers for
+	INST_LIST_INDEX_IMM, INST_LIST_RANGE_IMM and INST_START_CMD.
+
+2004-05-14  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclInt.decls:	     Promoted TclpLocaltime and TclpGmtime
+	* generic/tclIntDecls.h:     from Unix-specific stubs to the generic
+	* generic/tclIntPlatDecls.h: internal Stubs table. Reran 'genstubs'
+	* generic/tclStubInit.c:
+	* unix/tclUnixPort.h:
+
+	* generic/tclClock.c: Changed a buggy 'GMT' timezone specification
+			      to the correct 'GMT0'. [Bug 922848]
+
+	* unix/tclUnixThrd.c: Moved TclpGmtime and TclpLocaltime to
+			      unix/tclUnixTime.c where they belong.
+
+	* unix/tclUnixTime.c (TclpGmtime, TclpLocaltime, TclpGetTimeZone,
+			      ThreadSafeGMTime [removed],
+			      ThreadSafeLocalTime [removed],
+			      SetTZIfNecessary, CleanupMemory):
+	Restructured to make sure that the same mutex protects all calls to
+	localtime, gmtime, and tzset. Added a check in front of those calls to
+	make sure that the TZ env var hasn't changed since the last call to
+	tzset, and repeat tzset if necessary. [Bug 942078] Removed a buggy
+	test of the Daylight Saving Time information in 'gettimeofday' in
+	favor of applying 'localtime' to a known value. [Bug 922848]
+
+	* tests/clock.test (clock-3.14): Added test to make sure that changes
+	to $env(TZ) take effect immediately.
+
+	* win/tclWinTime.c (TclpLocaltime, TclpGmtime): Added porting layer
+	for 'localtime' and 'gmtime' calls.
+
+2004-05-14  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c:
+	* generic/tclCompile.h: the math functions receive a pointer to top of
+	the stack (tosPtr) instead of the execution environment (eePtr). First
+	step towards a change in the execution stack management - it is now
+	only used within TEBC.
+
+2004-05-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	TIP#143 IMPLEMENTATION
+
+	* generic/tclExecute.c (TclCompEvalObj, TclExecuteByteCode):

+	* generic/tclInterp.c (Tcl_Limit*): Public limit API.
+	* generic/tcl.decls:
+	* tests/interp.test: Basic tests of command limits.
+
+	* doc/binary.n:		TIP#129 IMPLEMENTATION [Patch 858211]
+	* generic/tclBinary.c:	Note that the test suite probably has many more
+	* tests/binary.test:	failures now due to alterations in constraints.
+
+2004-05-12  Miguel Sofer <msofer@users.sf.net>
+
+	Optimisations for INST_START_CMD [Bug 926164].
+	* generic/tclCompile.c (TclCompileScript): avoid emitting
+	INST_START_CMD as the first instruction in a bytecoded Tcl_Obj. It is
+	not needed, as the checks are done before calling TEBC.
+	* generic/tclExecute.c (TclExecuteByteCode): runtime peephole
+	optimisation: check at INST_POP if the next instruction is
+	INST_START_CMD, in which case we fall through.
+
+2004-05-11  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/split.n, doc/join.n: Updated examples and added more.

+
+2004-05-11  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+

+	to the scan command.
+
+2004-05-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/scan.n: Added examples.
+
+2004-05-10  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinPipe.c (BuildCommandLine): Moved non-obvious appending
+	logic to outside the loop and added commentary for its purpose. Also
+	use the existence of contents in the linePtr rather than the scratch
+	DString post the append, as this more clear.
+
+	(TclpCreateProcess): When under NT, with no console, and executing a
+	DOS application, the path priming does not need an ending space as
+	BuildCommandLine() will do this for us.
+
+2004-05-08  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclFileName.c:
+	* generic/tclIOUtil.c: remove some compiler warnings on MacOS X.
+
+2004-05-07  Chengye Mao <chengye.geo@yahoo.com>
+
+	* win/tclWinPipe.c: refixed bug 789040 re-entered in rev 1.41. Let's

+
+2004-05-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

+
+2004-05-07  Reinhard Max  <max@suse.de>
+

+
+	* generic/tclFileName.c:
+	* generic/tclIOUtil.c:
+	* generic/tclFileSystem.h:
+	* tests/fileSystem.test: fix for [Bug 943995], in which vfs-registered
+	root volumes were not handled correctly as glob patterns in all
+	circumstances.
+
+2004-05-06  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclInt.h:
+	* generic/tclObj.c (TclFreeObj): made TclFreeObj use the new macro
+	TclFreeObjMacro(), so that the allocation and freeing of Tcl_Obj is
+	defined in a single spot (the macros in tclInt.h), with the exception
+	of the TCL_MEM_DEBUG case.
+	The #ifdef logic for the corresponding macros has been reformulated to
+	make it clearer.

+
+2004-05-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+

+	such API. [Bug 848440]
+
+2004-05-05  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinSock.c (SocketEventProc) : connect errors should fire both
+	the readable and writable handlers because this is how it works on
+	UNIX [Bug 794839]
+
+	* generic/tclEncoding.c (TclFinalizeEncodingSubsystem):
+	FreeEncoding(systemEncoding); moved to before the hash table iteration
+	as it was causing a double free attempt under some conditions.
+
+	* win/coffbase.txt: Added the tls extension to the list of preferred
+	load addresses.

+	* generic/tclIO.c (Tcl_SetChannelOption): Fixed [SF Tcl Bug 930851].
+	When changing the eofchar we have to zap the related flags to prevent
+	them from prematurely aborting the next read.
+
+2004-04-25  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclPathObj.c: fix to [Bug 940281]. Tcl_FSJoinPath will now
+	always return a valid Tcl_Obj when the input is valid.
+	* generic/tclIOUtil.c: fix to [Bug 931823] for a more consistent
+	Tcl_FSPathSeparator() implementation which allows filesystems not to
+	implement their Tcl_FSFilesystemSeparatorProc if they wish to use the
+	default '/'. Also fixed associated memory leak seen with, e.g., tclvfs
+	package.
+	* doc/FileSystem.3: documented Tcl_FSJoinPath return values more
+	clearly, and Tcl_FSFilesystemSeparatorProc requirements.
+
+2004-04-23  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWin32Dll.c: Removed my mistake from 4/19 of adding an exit
+	handler to TclWinInit. TclWinEncodingsCleanup called from
+	TclFinalizeFilesystem does the Tcl_FreeEncoding for us.
+
+	* win/tclWinChan.c (Tcl_MakeFileChannel): Case for CloseHandle
+	returning zero and not throwing a
+	RaiseException(EXCEPTION_INVALID_HANDLE) now being done.
+
+2004-04-22  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tclEvent.c: TclSetLibraryPath's use of caching the stringrep
+	of the pathPtr object to TclGetLibraryPath called from another thread
+	was ineffective if the original's stringrep had been invalidated as
+	what happens when it gets muted to a list.
+
+	* win/tclWinTime.c: If the Tcl_ExitProc (StopCalibration) is called
+	from the stack frame of DllMain's PROCESS_DETACH, the wait operation
+	should timeout and continue.
+
+	* generic/tclInt.h:
+	* generic/tclThread.c:
+	* generic/tclEvent.c:
+	* unix/tclUnixThrd.c:
+	* win/tclWinThrd.c: Provisions made so masterLock, initLock, allocLock
+	and joinLock mutexes can be recovered during Tcl_Finalize.
+
+2004-04-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/switch.n: Reworked the examples to be more systematically named
+	and to cover some TIP#75 capabilities.
+
+	* doc/cd.n: Documentation clarification from David Welton.
+
+	* doc/exec.n: Added some examples, Windows ones from Arjen Markus and
+	Unix ones by myself.
+
+2004-04-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/Hash.3: Added note to Tcl_{First,Next}HashEntry docs that
+	deleting the element they return is supported (and is in fact the only
+	safe update you can do to the structure of a hashtable while an
+	iteration is going over it.)
+
+	* doc/bgerror.n: Added example from David Welton. [Patch 939473]
+
+	* doc/after.n: Added examples from David Welton. [Patch 938820]
+
+2004-04-19  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWin32Dll.c: Added an exit handler in TclWinInit() so
+	tclWinTCharEncoding could be freed during Tcl_Finalize().
+
+	* generic/tclEncoding.c: Added FreeEncoding(systemEncoding) in
+	TclFinalizeEncodingSubsystem because its ref count was incremented in
+	TclInitEncodingSubsystem.
+
+2004-04-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/read.n: Added example from David Welton. [Patch 938056]
+
+2004-04-19  Kevin B. Kenny   <kennykb@acm.org>
+
+	* generic/tclObj.c (Tcl_GetDoubleFromObj) Corrected "short circuit"
+	conversion of int to double. Reported by Jeff Hobbs on the Tcl'ers
+	Chat.
+
+2004-04-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/lreplace.n, doc/lrange.n, doc/llength.n:	More examples for
+	* doc/linsert.n, doc/lappend.n:			the documentation.
+
+2004-04-16  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* doc/FileSystem.3: Corrected documentation of Tcl_FSUtime, and the
+	corresponding filesystem driver Tcl_FSUtimeProc. [Bug 935838]
+
+2004-04-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* doc/socket.n: Added example from [Patch 936245].
+	* doc/gets.n: Added example based on [Patch 935911].
+
+2004-04-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclClock.c (Tcl_ClockObjCmd): Minor fault in a [clock
+	clicks] error message.
+
+2004-04-07  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* win/tclWinInit.c (TclpSetInitialEncodings): note that WIN32_CE is
+	also a unicode platform.
+	* generic/tclEncoding.c (TclFindEncodings, Tcl_FindExecutable):
+	* generic/tclInt.h:			    Correct handling of UTF
+	* unix/tclUnixInit.c (TclpInitLibraryPath): data that is actually
+	* win/tclWinFile.c (TclpFindExecutable):    "clean", allowing the
+	* win/tclWinInit.c (TclpInitLibraryPath):   loading of Tcl from paths
+	that contain multi-byte chars on Windows [Bug 920667]
+
+	* win/configure:    define TCL_LIB_FLAG, TCL_BUILD_LIB_SPEC,
+	* win/configure.in: TCL_LIB_SPEC, TCL_PACKAGE_PATH in tclConfig.sh.
+
+2004-04-06  Don Porter	<dgp@users.sourceforge.net>
+
+	Patch 922727 committed.	 Implements three changes:
+
+	* generic/tclInt.h:	Reworked the Tcl header files into a clean
+	* unix/tclUnixPort.h:	hierarchy where tcl.h < tclPort.h < tclInt.h
+	* win/tclWinInt.h:	and every C source file should #include
+	* win/tclWinPort.h:	at most one of those files to satisfy its
+	declaration needs. tclWinInt.h and tclWinPort.h also better organized
+	so that tclWinPort.h includes the Windows implementation of
+	cross-platform declarations, while tclWinInt.h makes declarations that
+	are available on Windows only.
+
+	* generic/tclBinary.c (TCL_NO_MATH):	Deleted the generic/tclMath.h
+	* generic/tclMath.h (removed):		header file. The internal Tcl
+	* macosx/Makefile (PRIVATE_HEADERS):	header, tclInt.h, has a
+	* win/tcl.dsp:				#include <math.h> directly,
+	and file external to Tcl needing libm should do the same.
+
+	* win/Makefile.in (WIN_OBJS):	Deleted the win/tclWinMtherr.c file.
+	* win/makefile.bc (TCLOBJS):	It's a vestige from matherr() days
+	* win/makefile.vc (TCLOBJS):	gone by.
+	* win/tcl.dsp:
+	* win/tclWinMtherr.c (removed):
+
+	End Patch 922727.
+
+	* tests/unixInit.test (unixInit-3.1):	Default encoding on Darwin
+	systems is utf-8. Thanks to Steven Abner (tauvan). [Bug 928808]
+
+2004-04-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* tests/cmdAH.test (cmdAH-18.2): Added constraint because
+	access(...,X_OK) is defined to be permitted to be meaningless when
+	running as root, and OSX exhibits this. [Bug 929892]
+
+2004-04-02  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCompile.c:
+	* generic/tclInt.h: removed the macro TCL_ALIGN() from tclInt.h,
+	replaced by the static macro ALIGN() in tclCompile.c [Bug 926445]
+
+2004-04-02  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCompile.h: removed redundant #ifdef _TCLINT [Bug 928415],
+	reported by tauvan.
+
+2004-04-02  Don Porter	<dgp@users.sourceforge.net>
+
+	* tests/tcltest.test: Corrected constraint typos: "nonRoot" ->
+	"notRoot". Thanks to Steven Abner (tauvan). [Bug 928353]
+
+2004-04-01  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclInt.h:  Removed obsolete tclBlockTime* declarations. [Bug
+	926454]
+
+2004-04-01  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c: Fix to privately reported vfs bug with 'glob
+	-type d -dir . *' across a vfs boundary. No tests for this are
+	currently possible without effectively moving tclvfs into Tcl's test
+	suite.
+
+2004-03-31  Don Porter	<dgp@users.sourceforge.net>
+
+	* doc/msgcat.n:	Clarified message catalog file encodings. [Bug 811457]
+	* library/msgcat/msgcat.tcl: Updated internals to make use of [dict]s
+	to store message catalog data and to use [source -encoding utf-8] to
+	access catalog files. Thanks to Michael Sclenker. [Patch 875055, RFE
+	811459] Corrected [mcset] to be able to successfully set a translation
+	to the empty string. [mcset $loc $src {}] was incorrectly set the $loc
+	translation of $src back to $src. Also changed [ConvertLocale] to
+	minimally require a non-empty "language" part in the locale value. If
+	not, an error raised prompts [Init] to keep looking for a valid locale
+	value, or ultimately fall back on the "C" locale. [Bug 811461].
+	* library/msgcat/pkgIndex.tcl:	Bump to msgcat 1.4.1.
+
+2004-03-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclHash.c (HashStringKey): Cleaned up. This function is not
+	faster, but it is a little bit clearer.
+	* generic/tclLiteral.c (HashString): Applied logic from HashObjKey.
+	* generic/tclObj.c (HashObjKey): Rewrote to fix fault which hashed
+	every single-character object to the same hash bucket. The new code is
+	shorter, simpler, clearer, and (happily) faster.
+
+2004-03-30  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclExecute.c (TEBC): reverting to the previous method for
+	async tests in TEBC, as the new method turned out to be too costly.
+	Async tests now run every 64 instructions.
+
+2004-03-30  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCompile.c:	    New instruction code INST_START_CMD that
+	* generic/tclCompile.h:	    allows checking the bytecode's validity
+	* generic/tclExecute.c:	    [Bug 729692] and the interp's readyness
+	* tests/interp.test (18.9): [Bug 495830] before running the command.
+	* tests/proc.test (7.1):    It also changes the mechanics of the async
+	* tests/rename.test (6.1):  tests in TEBC, doing it now at command
+	start instead of every 16 instructions.
+
+2004-03-30  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclFileName.c:  Fix to Windows glob where the pattern is a
+	* generic/tclIOUtil.c:	  volume relative path or a network share [Bug
+	* tests/fileName.test:	  898238]. On windows 'glob' will now return
+	* tests/fileSystem.test:  the results of 'glob /foo/bar' and 'glob
+	\\foo\\bar' as 'C:/foo/bar', i.e. a correct absolute path (rather than
+	a volume relative path).
+
+	Note that the test suite does not test commands like
+	'glob //Machine/Shared/*' (on a network share).
+
+2004-03-30  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclPathObj.c:	  Fix to filename bugs recently
+	* tests/fileName.test:	  introduced [Bug 918320].
+
+2004-03-29  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclMain.c (Tcl_Main, StdinProc):	Append newline only
+	* tests/basic.test (basic-46.1):		to incomplete scripts
+	as part of multi-line script construction. Do not add an extra
+	trailing newline to the complete script. [Bug 833150]
+
+2004-03-28  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCompile.c (TclCompileScript): corrected possible segfault
+	when a compilation returns TCL_OUTLINE_COMPILE after having grown the
+	compile environment [Bug 925121].
+
+2004-03-27  Miguel Sofer <msofer@users.sf.net>
+
+	* doc/array.n: added documentation for trace-realted behaviour of
+	'array get' [Bug 449893]
+
+2004-03-26  Don Porter	<dgp@users.sourceforge.net>

+
+	* generic/tclPathObj.c:	  Fix to Windows-only volume relative path
+	* tests/fileSystem.test:  normalization. [Bug 923568]. Also fixed
+	another volume relative bug found while testing.
+
+2004-03-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclNamesp.c (NsEnsembleImplementationCmd): Fix messed up
+	handling of strncmp result which just happened to work in some libc
+	implementations. [Bug 922752]
+
+2004-03-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+

+	fix recommended by Don Porter.
+
+2004-03-18  Reinhard Max  <max@suse.de>
+
+	* generic/tclIntDecls.h: Removed TclpTime_t. It wasn't really needed,

+	accurate. I removed the check on the case result==(WAIT_OBJECT_0 + 1)
+	This was having the error of falling into GetMessage and waiting there
+	by accident, which wasn't alertable through Tcl_AlertNotifier. I'll do

+	[Bug 500285] and wrong GMT base date [Bug 913513]. Several tests still
+	fail on Windows, and these are actual faults in [clock scan]. Fix is

+	* win/tclWinPort.h: If MWMO_ALERTABLE is not defined in winuser.h then
+	define it. This is needed for Mingw.
+
+2004-03-05  Kevin B. Kenny <kennykb@acm.org>
+
+	* generic/tclTest.c: Modified TesteventObjCmd to use a
+	Tcl_QueuePosition in place of an 'int' for the enumerated queue
+	position, to avoid a compiler warning on SGI. [Bug 771960]
+
+2004-03-05  Kevin B. Kenny <kennykb@acm.org>
+
+	* tests/registry.test: Applied fix from [Patch 910174] to make the test
+	for an English-language system include any country code, rather than
+	just English-United States.1252. Thanks to Pat Thoyts for the changes.
+
+2004-03-04  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* tests/registry.test: Applied fixed from [Bug 766159] to skip two
+	tests on Win98 that depend on a Unicode registry (NT specific).
+
+2004-03-04  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclInt.h (TclParseInit):	Factored the common code
+	* generic/tclParse.c (TclParseInit):	for initializing a Tcl_Parse
+	* generic/tclParseExpr.c:		struct into one routine.
+
+2004-03-04  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* library/reg/pkgIndex.tcl:  Added TIP #100 support to the
+	* win/tclWinReg.c:	     registry package [patch 903831]
+	This provides a Windows test of the TIP #100 mechanism and a sample to
+	show how unloading an extension can be done.
+
+2004-03-04  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* unix/dltest/pkgua.c: Fix minor syntax problems. [Bug 909288]
+
+2004-03-03  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	*** 8.5a1 TAGGED FOR RELEASE ***
+
+	* changes: updated for 8.5a1
+
+2004-03-03  David Gravereaux <davygrvy@pobox.com>
+
+	* win/makefile.vc: default environment variable for VC++ is %MSDevDir%
+	not %MSVCDir%, although vcvars32.bat sets both.
+
+	* win/tclWinNotify.c (Tcl_WaitForEvent) : Allows an idling notifier to
+	service "Asynchronous Procedure Calls" from its wait state. Only
+	useful for extension authors who decide they might want to try
+	"completion routines" with WriteFileEx(), as an example. From
+	experience, I recommend that "completion ports" should be used instead
+	as the execution of the callbacks are more managable.
+
+2004-03-01  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* README:	    update patchlevel to 8.5a1

+
+	* generic/tclTrace.c (TclCheckInterpTraces):	The TIP 62
+	* generic/tclTest.c (TestcmdtraceCmd):	implementation introduced a
+	* tests/trace.test (trace-29.10):	bug by testing the CallFrame
+	level instead of the iPtr->numLevels level when deciding what traces
+	created by Tcl_Create(Obj)Trace to call. Added test to expose the
+	error, and made fix. [FRQ 462580]
+
+2004-02-28  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* tests/fileSystem.test: fix to Tcl Bug 905163.
+	* tests/fileName.test: fix to Tcl Bug 904705.
+
+	* doc/{various}.n: removed 'the the' typos.
+
+2004-02-26  Daniel Steffen  <das@users.sourceforge.net>
+

+
+2004-02-25  Don Porter	<dgp@users.sourceforge.net>
+
+	* tests/basic.test:	Made several tests more robust to the
+	* tests/cmdMZ.test:	list-quoting of path names that might contain

+2004-02-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclLoad.c (Tcl_LoadObjCmd): Missing dereference caused
+	segfault with non-loadable extension. [Bug 904307]
+
+	* unix/tclUnixChan.c (TcpGetOptionProc): Stop memory leak with very
+	long hostnames. [Bug 888777]
+
+2004-02-25  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* win/tclWinDde.c: Removed some gcc warnings - except for the
+	-Wconversion warning for GetGlobalAtomName. gcc is just wrong about
+	this.
+
+2004-02-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	IMPLEMENTATION OF TIP#100 FROM GEORGIOS PETASIS
+	* generic/tclLoad.c (Tcl_UnloadObjCmd): Implementation.
+	* tests/unload.test:			Test suite.
+	* unix/dltest/pkgua.c:			Helper for test suite.
+	* doc/unload.n:				Documentation.
+	Also assorted changes (mostly small) to several other files.
+
+2004-02-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/regc_locale.c (cclass): Buffer was having its size reset
+	instead of being released => memleak. [Bug 902562]
+
+2004-02-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclLoad.c (Tcl_LoadObjCmd): Fixed memory leak due to an
+	improper error exit route.
+
+2004-02-20  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinSock.c (SocketThreadExitHandler): Don't call
+	TerminateThread when WaitForSingleObject returns a timeout.
+	Tcl_Finalize called from DllMain will pause all threads. Trust that
+	the thread will get the close notice at a later time if it does ever
+	wake up before being cleaned up by the system anyway.
+
+2004-02-17  Don Porter	<dgp@users.sourceforge.net>
+
+	* doc/tcltest.n:
+	* library/tcltest/tcltest.tcl:	Changed -verbose default value to
+	{body error} so that detailed information on unexpected errors in
+	tests is provided by default, even after the fix for [Bug 725253]
+
+2004-02-17  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* tests/unixInit.test (unixInit-7.1):
+	* unix/tclUnixInit.c (TclpInitPlatform): ensure the std fds exist to
+	prevent crash condition [Bug 772288]
+
+2004-02-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclCompCmds.c (TclCompileSwitchCmd): Bozo mistake in memory
+	releasing order when in an error case. [Bug 898910]
+
+2004-02-16  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* generic/tclTrace.c (TclTraceExecutionObjCmd)
+	(TclTraceCommandObjCmd): fix possible mem leak in trace info.
+
+2004-02-12  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/tclWinInit.c (AppendEnvironment): Use the tail component of the
+	passed in lib path instead of just blindly using lib+4. That worked
+	when lib was "lib/..." but fails for other values. Thanks go to
+	Patrick Samson for pointing this out.
+
+2004-02-10  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/nmakehlp.c: better macro grepping logic.
+
+2004-02-07  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/makefile.vc:
+	* win/rules.vc:
+	* win/tcl.rc:
+	* win/tclsh.rc: Added an 'unchecked' option to the OPTS macro so a
+	core built with symbols can be linked to the non-debug enabled C
+	run-time. As per discussion with Kevin Kenny. Called like this:
+
+		nmake -af makefile.vc OPTS=unchecked,symbols
+
+	This clarifies the meaning of the 'g' naming suffix to mean only that
+	the binary requires the debug enabled C run-time. Whether the binary
+	contains symbols or not is a different condition.
+
+2004-02-06  Don Porter	<dgp@users.sourceforge.net>
+
+	* doc/clock.n:	Removed reference to non-existent [file ctime].
+
+2004-02-05  David Gravereaux  <davygrvy@pobox.com>
+
+	* docs/tclvars.n: Added clarification of the tcl_platform(debug) var
+	that it only refers to the flavor of the C run-time, and not whether
+	the core contains symbols.
+
+2004-02-05  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclFileName.c (SkipToChar): Corrected CONST and type-casting
+	issues that caused compiler warnings.
+
+2004-02-04  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdAH.c (StoreStatData): Removed improper refcount
+	decrement of the varName parameter. This error was causing segfaults
+	following test cmdAH-28.7.
+
+	* library/tcltest/tcltest.tcl: Corrected references to non-existent
+	$name variable in [cleanupTests]. [Bug 833637]
+
+2004-02-03  Don Porter	<dgp@users.sourceforge.net>
+
+	* library/tcltest/tcltest.tcl:	Corrected parsing of single command
+	line argument (option with missing value) [Bug 833910]
+	* library/tcltest/pkgIndex.tcl:	Bump to version 2.2.5.
+
+2004-02-02  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tclIO.c (Tcl_Ungets): Fixes improper filling of the channel
+	buffer. This is the buffer before the splice. [Bug 405995]
+
+2004-02-01  David Gravereaux <davygrvy@pobox.com>
+
+	* tests/winPipe.test: more pass-thru commandline verifications.
+	* win/tclWinPipe.c (BuildCommandLine): Special case quoting for '{'
+	not required by the c-runtimes's parse_cmdline().
+	* win/tclAppInit.c: Removed our custom setargv() in favor of the work
+	provided by the c-runtime. [Bug 672938]
+
+	* win/nmakehlp.c: defensive techniques to avoid static buffer
+	overflows and a couple envars upsetting invokations of cl.exe and
+	link.exe. [Bug 885537]
+
+	* tests/winPipe.test: Added proof that BuildCommandLine() is not doing
+	the "N backslashes followed a quote -> insert N * 2 + 1 backslashes
+	then a quote" rule needed for the crt's parse_cmdline().
+	* win/tclWinPipe.c: Fixed BuildCommandLine() to pass the new cases.
+
+2004-01-30  David Gravereaux <davygrvy@pobox.com>
+
+	* win/makefile.vc: Use the -GZ compiler switch when building for
+	symbols. This is supposed to emulate the release build better to avoid
+	hiding problems that only show themselves in a release build.
+
+2004-01-29  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclPathObj.c: fix to [Bug 883143] in file normalization
+
+2004-01-29  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* doc/file.n:
+	* generic/tclFCmd.c
+	* generic/tclTest.c
+	* library/init.tcl
+	* mac/tclMacFile.c
+	* tests/fileSystem.test: fix to [Bug 886352] where 'file copy -force'
+	had inconsistent behaviour wrt target files with insufficient
+	permissions, particular from vfs->native fs. Behaviour of '-force' is
+	now always consistent (and now consistent with behaviour of 'file
+	delete -force'). Added new tests and documentation and cleaned up the
+	'simplefs' test filesystem.
+
+	* generic/tclIOUtil.c
+	* unix/tclUnixFCmd.c
+	* unix/tclUnixFile.c
+	* win/tclWinFile.c: made native filesystems more robust to C code
+	which asks for mount lists.
+
+	* generic/tclPathObj.c: fix to [Bug 886607] removing warning/error
+	with some compilers.
+
+2004-01-28  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclObj.c (SetBooleanFromAny): Rewrite to do more efficient
+	string->bool conversion.
+	Many other minor whitespace/style fixes to this file too.
+
+2004-01-27  David Gravereaux <davygrvy@pobox.com>
+
+	* win/nmakehlp.c: Use '.\nul' as the sourcefile name instead of 'nul'
+	so VC 5.2 doesn't try searching the path for it and failing with a
+	possible dialogbox popping up about having to add a CD to an empty
+	drive. Also added a SetErrorMode() call to disable any dialogs that
+	cl.exe or link.exe might create. [Bug 885537]
+
+2004-01-22  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* doc/file.n: clarified documentation of 'file system' [Bug 883825]
+	* tests/fCmd.test: improved test result in failure case.
+
+2004-01-22  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* tests/fileSystem.test: 3 new tests
+	* generic/tclPathObj.c: fix to [Bug 879555] in file normalization.
+	* doc/filename.n: small clarification to Windows behaviour with
+	filenames like '.....', 'a.....', '.....a'.
+
+	* generic/tclIOUtil.c: slight improvement to native cwd caching on
+	Windows.
+
+2004-01-21  David Gravereaux <davygrvy@pobox.com>
+
+	* doc/Panic.3:	Mentions of 'panic' and 'panicVA' removed from the
+	documentation.
+
+2004-01-21  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* doc/FileSystem.3:
+	* generic/tcl.decls:
+	* generic/tclCmdAH.c
+	* generic/tclDecls.h
+	* generic/tclFCmd.c
+	* generic/tclFileName.c
+	* generic/tclFileSystem.h
+	* generic/tclIOUtil.c
+	* generic/tclInt.decls
+	* generic/tclInt.h
+	* generic/tclIntDecls.h

+	* tests/winFCmd.test
+	* unix/tclUnixFile.c
+	* win/tclWin32Dll.c
+	* win/tclWinFCmd.c
+	* win/tclWinFile.c
+	* win/tclWinInt.h
+
+	Three main issues accomplished: (1) cleaned up variable names in the
+	filesystem code so that 'pathPtr' is used throughout. (2) applied a
+	round of filesystem optimisation with better handling and caching of
+	relative and absolute paths, requiring fewer conversions. (3)
+	clarifications to the documentation, particularly regarding the
+	acceptable refCounts of objects. Some new tests added. Tcl benchmarks
+	show a significant improvement over 8.4.5, and on Windows typically a
+	small improvement over 8.3.5 (Unix still appears to require
+	optimisation). TCL_FILESYSTEM_VERSION_2 introduced, but for internal
+	use only. There should be no public incompatibilities from these
+	changes. Thanks to dgp for extensive testing.
+
+2004-01-19  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinPipe.c (Tcl_WaitPid): Fixed a thread-safety problem with
+	the process list. The delayed cut operation after the wait was going
+	stale by being outside the list lock. It now cuts within the lock and
+	does a locked splice for when it needs to instead. [Bug 859820]
+
+2004-01-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclCompile.c, generic/tclCompile.h: Two new opcodes,
+	INST_LIST_INDEX_IMM and INST_LIST_RANGE_IMM, that have operand(s) of
+	new type OPERAND_IDX4 which represents indexes into things like lists
+	(and perhaps other things eventually.)
+	* generic/tclExecute.c (TclExecuteByteCode): Implementation of the new
+	opcodes. INST_LIST_INDEX_IMM does a simple [lindex] with either front-
+	or end-based simple indexing. INST_LIST_RANGE_IMM does an [lrange]
+	with front- or end-based simple indexing for both the reference to the
+	first and last items in the range.
+	* generic/tclCompCmds.c (TclCompileLassignCmd): Generate bytecode for
+	the [lassign] command.
+
+2004-01-17  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinInit.c: added #pragma comment(lib, "advapi32.lib") when
+	compiling under VC++ so we don't need to specify it when linking.
+
+2004-01-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclCmdIL.c (Tcl_LassignObjCmd): Add more shimmering
+	protection for when the list is also one of the variables.
+
+	BASIC IMPLEMENTATION OF TIP#57
+	* generic/tclCmdIL.c (Tcl_LassignObjCmd): Implementation of the
+	[lassign] command that takes full advantage of Tcl's object API.
+	* doc/lassign.n: New file documenting the command.
+	* tests/cmdIL.test (cmdIL-6.*): Test suite for the command.
+
+2004-01-15  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinReg.c: Placed the requirement for advapi.lib into the
+	object file itself with #pragma comment (lib, ...) when built with
+	VC++. This will simplify linking for users of the static library.
+
+	* win/rules.vc: Added new 'fullwarn' to the CHECKS commandline macro;
+	sets $(FULLWARNINGS).
+
+	* win/makefile.vc: Removed 'advapi.lib' from $(baselibs). Added new
+	logic to crank-up the warning levels for both compile and link when
+	$(FULLWARNINGS) is set. Some clean-up with how the resource files are
+	built and how -DTCL_USE_STATIC_PACKAGES is sent when compiling the
+	shells.
+
+	* win/tclAppInit.c: Small change in how TCL_USE_STATIC_PACKAGES is
+	used.
+
+	* win/tcl.rc:
+	* win/tclsh.rc: Some clean-up with how the resource files are built.
+	Fixed 'OriginalFilename' problem that still thought a debug suffix was
+	still 'd', now is 'g'.
+
+2004-01-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclDictObj.c (TraceDictPath, DictExistsCmd): Adjusted
+	behaviour of [dict exists] so a failure to look up a dictionary along
+	the path of dicts doesn't trigger an error. This is how it was
+	documented to behave previously... [Bug 871387]
+
+	* generic/tclDictObj.c: Assorted dict fixes from Peter Spjuth relating
+	to [Bug 876170].
+	(SetDictFromAny): Make sure that lists retain their ordering even when
+	converted to dictionaries and back.
+	(TraceDictPath): Correct object reference count handling!
+	(DictReplaceCmd, DictRemoveCmd): Stop object leak.
+	(DictIncrCmd,DictLappendCmd,DictAppendCmd,DictSetCmd,DictUnsetCmd):
+	Simpler handling of reference counts when assigning to variables.
+	* tests/dict.test (dict-19.2): Memory leak stress test
+
+2004-01-13  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd):  Silence compiler warnings.
+
+	Patch 876451: restores performance of [return]. Also allows forms such
+	as [return -code error $msg] to be bytecompiled.
+
+	* generic/tclInt.h:	Factored Tcl_ReturnObjCmd() into two pieces:
+	* generic/tclCmdMZ.c:	TclMergeReturnOptions(), which can parse the
+	options to [return], check their validity, and create the
+	corresponding return options dictionary, and TclProcessReturn(), which
+	takes that return options dictionary and performs the [return]
+	operation.
+
+	* generic/tclCompCmds.c: Rewrote TclCompileReturnCmd() to call
+	TclMergeReturnOptions() at compile time so the return options
+	dictionary is computed at compile time (when it is fully known). The
+	dictionary is pushed on the stack along with the result, and the code
+	and level values are included in the bytecode as operands. Also
+	supports optimized compilation of un-[catch]ed [return]s from procs
+	with default options into the INST_DONE instruction.
+
+	* generic/tclExecute.c: Rewrote INST_RETURN instruction to retrieve
+	the code and level operands, pop the return options from the stack,
+	and call TclProcessReturn() to perform the [return] operation.
+
+	* generic/tclCompile.h:	New utilities include TclEmitInt4 macro
+	* generic/tclCompile.c:	and TclWordKnownAtCompileTime().
+
+	End Patch 876451.
+
+	* generic/tclFileName.c (Tcl_GlobObjCmd): Latest changes to management
+	of the interp result by Tcl_GetIndexFromObj() exposed improper interp
+	result management in the [glob] command procedure. Corrected by
+	adopting the Tcl_SetObjResult(Tcl_NewStringObj) pattern. This stopped
+	a segfault in test filename-11.36. [Bug 877677]
+
+2004-01-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct, Tcl_WrongNumArgs):
+	Create fresh objects instead of using the one currently in the
+	interpreter, which isn't guaranteed to be fresh and unshared. The cost
+	for the core will be minimal because of the object cache, and this
+	fixes [Bug 875395].
+
+2004-01-12  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCompExpr.c (CompileLandOrLorExpr): cosmetic changes.
+
+2004-01-12  Miguel Sofer <msofer@users.sf.net>
+
+	* generic/tclCompExpr.c (CompileLandOrLorExpr): new logic, fewer
+	instructions. As a side effect, the instructions INST_LOR and
+	INST_LAND are now never used.
+	* generic/tclExecute.c (INST_JUMP*): small optimisation; fix a bug in
+	debug code.
+
+2004-01-11  David Gravereaux <davygrvy@pobox.com>
+
+	* win/tclWinThrd.c (Tcl_ConditionNotify): condPtr must be dereferenced
+	to see if there are waiters else uninitialized datum is manipulated.
+	[Bug 849007 789338 745068]
+
+2004-01-09  David Gravereaux <davygrvy@pobox.com>
+
+	* generic/tcl.h: Renamed and deprecated #defines moved to within the
+	#ifndef TCL_NO_DEPRECATED block. This allows us to build Tcl to check
+	for deprecated functions in use, such as panic() and Tcl_Ckalloc(). By
+	request from DKF. Extensions that build with -DTCL_NO_DEPRECATED now
+	have these macros as restricted.
+	***POTENTIAL INCOMPATIBILITY***
+
+	* win/makefile.vc:
+	* win/rules.vc:	 Added -DTCL_NO_DEPRECATED usage to makefile.vc.
+	Called like this:   nmake -af makefile.vc CHECKS=nodep
+
+2004-01-09  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclIOUtil.c: fix to infinite loop in TclFinalizeFilesystem
+	[Bug 873311]

+
+	* generic/tcl.decls:  Destubbed TclTomMathInitializeStubs - it is in
+	* generic/tcl.h:      the stub library, not the main shared
+	* generic/tclBasic.c: library. Exported Tcl_InitBignumFromDouble.
+	* generic/tclExecute.c:
+	* generic/tclInt.h:
+	* generic/tclStrToD.c:
+
+	* generic/tclDecls.h:
+	* generic/tclStubLib.c:
+	* generic/tclStubInit.c: Regenerated.
+
+	* generic/clock.tcl: Reverted to using the time zone abbreviation and
+	not its name to "stop the bleeding" on [Bug 1386377]. This is *not* a
+	good long-term solution, but there may not be one.
+
+	* libtommath/bn_mp_sqrt.c: Improved the initial approximation to the
+	square root, roughly doubling the speed of the routine. (This is a
+	local change that needs to be communicated to Tom.)
+
+	* win/Makefile.in: Corrected a bug where tommath_class.h and
+	tommath_superclass.h were not installed, making it impossible for
+	client code to compile against the tommath stubs.
+
+	* library/tzdata: Updated to Olson's tzdata2005r. (Latest changes to
+	Daylight Saving Time in Canada, plus redefinition of the Posix-style
+	zones [e.g., EST5EDT] to be locale-independent.)
+
+	* libtommath: Updated to Tom St.Denis's release 0.37.
+
+2005-12-20  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclThreadAlloc.c (Tcl_GetMemoryInfo): Format values as longs
+	and not ints, so they are less likely to wrap on 64-bit machines.
+
+2005-12-19  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c:	Modified [string is double] to use
+	* tests/string.test:	TclParseNumber() to parse trailing whitespace.
+	Ensures consistency, and makes it easier to cleanup after invalid
+	internal reps left behind by parsing [Bugs 1360532 1382287].
+
+	* generic/tclParseExpr.c:	Added TCL_PARSE_NO_WHITESPACE to
+	* generic/tclScan.c:	TclParseNumber() calls since [scan] and [expr]
+	* tests/scan.test:	parsing don't want spaces in parsed numbers.
+
+	* generic/tclInt.h:	Added TCL_PARSE_NO_WHITESPACE flag to the
+	* generic/tclStrToD.c:	TclParseNumber() interface.
+
+2005-12-19  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* doc/Tcl.n: Clarify what is going on in variable substitution
+	following thread on comp.lang.tcl.
+
+2005-12-18  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclCompCmds.c (TclCompileDictCmd): Ensure that we only do an
+	'endCatch' when there's a preceding 'beginCatch'. [Bug 1382528] Many
+	thanks to Anton Kovalenko for finding this and pointing out that it was
+	a catch stack handling problem!
+
+2005-12-14  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclIOUtil.c: workaround gcc warning "comparison is always
+	* generic/tclTest.c:   false due to limited range of data type".
+
+	* macosx/Tcl.xcode/project.pbxproj:
+	* macosx/Tcl.xcodeproj/project.pbxproj:
+	* unix/Makefile.in: add new tclTomMath* files.
+
+	* generic/tclBasic.c: replace panic with Tcl_Panic.
+
+2005-12-13  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tcl.decls:    Added changes to export an additional stubs
+	* generic/tclBasic.c:   table to represent the 'libtommath' routines
+	* generic/tclDecls.h:   that Tcl uses and export them to callers.
+	* generic/tclInt.decls: Reran 'genstubs'
+	* generic/tclInt.h:
+	* generic/tclIntDecls.h:
+	* generic/tclIntPlatDecls.h:
+	* generic/tclStubInit.c:

+	* unix/Makefile.in:
+	* win/Makefile.in:
+	* win/makefile.vc:
+
+	* generic/tclClock.c:   Made changes to silence a number of compiler
+	* generic/tclIO.c:	warnings when building with mingw.
+	* generic/tclIORChan.c:
+	* generic/tclLink.c:
+	* generic/tclListObj.c:

+
+2005-12-13  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclExecute.c (TEBC:DICT_FIRST,DICT_DONE): Only decrease the
+	references to the dictionary once the iteration completes. Do this by
+	storing the dict in the iterator context variable. [Bug 1379349] Thanks
+	to Ulrich Ring and Tobias Hippler for finding this.
+
+2005-12-12  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* unix/tcl.m4, unix/configure: Fix sh quoting error reported in
+	bash-3.1+ [Bug 1377619] (schafer)
+
+2005-12-12  Kevin B. Kenny  <kennykb@acm.org>
+
+	* doc/mathfunc.n: Changed two examples from the incorrect 'tcl::math::'
+	to 'tcl::mathfunc::' [Bug 1378818]
+
+2005-12-09  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* win/configure: Regen.
+	* win/tcl.m4 (SC_CONFIG_CFLAGS): Define MACHINE for gcc builds. The
+	lack of a definition of this variable in the manifest file was causing
+	a runtime error in wish built with gcc.
+
+2005-12-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* tests/lsearch.test (lsearch-10.8..10):  If the -start is off the end,
+	* generic/tclCmdIL.c (Tcl_LsearchObjCmd): searching should find nothing
+	at all. [Bug 1374778]
+
+2005-12-08  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/Makefile.in, win/makefile.vc: Add Win x64 and CE build support
+	* win/tcl.m4, win/configure:        CE still requires C code fixes.
+
+	* generic/tcl.h: use struct __stat64 (not _stat64) for MSC_VER >= 1400
+	(i.e. latest Platform SDK).
+
+2005-12-07  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* doc/socket.n: Cross-referenced the socket documentation better to the
+	fconfigure documentation on the topic of asynch sockets.
+	* doc/fconfigure.n: Added keyword to documentation of -blocking option
+	so that people looking for "asynch" can find it as well.
+
+2005-12-05  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tclUnixPort.h (Darwin): fix incorrect __DARWIN_UNIX03 configure
+	overrides that were originally copied from Darwin CVS (rdar://3693001)
+
+2005-12-05  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tools/tclZIC.tcl: Updated to reflect changes in calling sequence when
+	GetJulianDateFromEraYearMonthDay moved to C.
+	* library/tzdata: Regenerated from Olson's tzdata2005p.tar.gz - the
+	'systemv' changes appear not to affect Tcl's processing of the dates.
+
+2005-12-05  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/configure.in: move check for fts API to configure.in and run it
+	* unix/tcl.m4:       on all platforms, since Linux glibc2 and *BSDs
+	also have this; using fts is more efficient than a recursive
+	opendir/readdir.
+	* unix/tclUnixFCmd.c (TraverseUnixTree): add support to fts code for
+	platforms with stat64.
+	* unix/configure:
+	* unix/tclConfig.h.in: regen.
+
+2005-12-05  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* unix/configure:     Use fts file API on Darwin if available.
+	* unix/tcl.m4:        Addresses file delete issues in readdir noted
+	* unix/tclUnixFCmd.c: in [Bug 1034337]. (steffen)
+	Remove redundant stat call for each file in DoCopyFile. (steffen)
+
+2005-12-02  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclClock.c: Moved a tiny bit more of [clock format] from run
+	* library/clock.tcl: time to compile time, and fixed a l10n bug in the
+	process. [Bug 1371446]. Also, conditoned the call to SetupTimeZone to
+	speed the common case where TZData($timezone) already exists, and
+	achieved a puny speedup by making ::tcl::clock::getenv not throw
+	errors.
+	* unix/Makefile.in: Made some changes to support a 'make' command that
+	is present on some antiquated versions of Solaris.
+
+2005-12-01  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl: Continued rationalizing the code, eliminating
+	numerous redundant [mc] calls. Added another time boost by precompiling
+	a [::format] command to do the bulk of the work of [clock format].
+
+2005-12-01  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* unix/Makefile.in: Add remaining dependency info. While automated
+	maintenance of this information would be good, having it at all is much
+	better than a poke in the eye with a sharp stick...
+
+2005-12-01  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclClock.c: fix warning.
+
+	* unix/tcl.m4 (Darwin): fix error when MACOSX_DEPLOYMENT_TARGET unset
+	* unix/configure: regen.
+
+2005-11-30  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* unix/Makefile.in: Add dependency information relating to tclCompile.h
+	since when the list of opcodes changes it is usually useful to rebuild
+	everything that depends on it (but which is nonetheless a small
+	fraction of the total set of Tcl source files).
+
+	***POTENTIAL INCOMPATIBILITY*** for bytecode savers/loaders. See below
+
+	* generic/tclCompCmds.c (TclCompileSwitchCmd): Arrange for very simple
+	[switch] invokations to be compiled into hash lookups into jump tables;
+	only a very specific kind of [switch] can be safely compiled this way,
+	but that happens to be the most common kind. This makes around 5-10%
+	difference to the speed of execution of clock.test.
+	* generic/tclExecute.c (TEBC:INST_JUMP_TABLE): New instruction to allow
+	for jumps to locations looked up in a hashtable. Requires a new AuxData
+	type, tclJumptableInfoType (supported by the functions DupJumptableInfo
+	and FreeJumptableInfo in tclCompCmds.c) so anything that saves bytecode
+	containing this *must* be updated!
+
+2005-11-30  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclClock.c: Fixed a bad refcount in previous commit that led
+	to a corrupted heap. Also silenced a warning that some compilers gave
+	about the excessively long constant for JULIAN_SEC_POSIX_EPOCH. Also
+	fixed a bug where [clock format] would fail in the :localtime zone for
+	times before the Posix Epoch. Thanks to Miguel Sofer for pointing out
+	all of these. Also rationalized the code a little bit by moving parts
+	of [clock scan] into C, eliminating some code that was duplicated in
+	the C and Tcl layers.
+
+2005-11-29  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclBasic.c:	Moved a big part of [clock format] down
+	* generic/tclClock.c:   to the C level in order to make it go faster.
+	* generic/tclInt.h:     Preliminary measurements suggest that it
+	* generic/clock.tcl:    more than doubles in speed with this change.
+
+2005-11-29  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclCmdIL.c (Tcl_LsearchObjCmd): Allow [lsearch -regexp] to
+	process REs that contain backreferences. This expensive mode of
+	operation is only used if the RE would otherwise cause a compilation
+	failure. [Bug 1366683]
+
+2005-11-28  Kevin Kenny  <kennykb@acm.org>
+
+	* tools/tclZIC.tcl (convertTimeOfDay): Corrected a typo that caused
+	wrong DST transitions in any time zone where the transition is
+	specified as local Standard Time (as opposed to wall-clock or UTC).
+	(Also updated the code to be bignum-safe.)
+	* tests/clock.test (clock-51.1): Added regression test for the above.
+	* library/tzdata: Updated to Olson's 'tzdata2005o' (changes for Cuba,
+	Nicaragua, Jordan, and Georgia) and regenerated. Thanks to Paul
+	Mackerras for reporting this problem.
+
+2005-11-27  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tcl.m4 (Darwin): add 64bit support, check for Tiger copyfile(),
+	add CFLAGS to SHLIB_LD to support passing -isysroot in env(CFLAGS) to
+	configure (flag can't be present twice, so can't be in both CFLAGS and
+	LDFLAGS during configure), don't use -prebind when deploying on 10.4,
+	define TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING (rdar://3171542).
+	(SC_ENABLE_LANGINFO, SC_TIME_HANDLER): add/fix caching, fix obsolete
+	autoconf macros. Sync with tk/unix/tcl.m4.
+
+	* unix/configure.in: fix obsolete autoconf macros, sync gratuitous
+	formatting/ordering differences with tk/unix/configure.in.
+
+	* unix/Makefile.in: add CFLAGS to tclsh/tcltest link to make executable
+	linking the same as during configure (needed to avoid losing any linker
+	relevant flags in CFLAGS, in particular flags that cannot be in
+	LDFLAGS). Avoid concurrent linking of tclsh and compiling of
+	tclTestInit.o or xtTestInit.o during parallel make.
+	(checkstubs, checkdoc, checkexports): dependency and Darwin fixes
+	(dist): add new macosx files.
+
+	* unix/tclLoadDyld.c (TclpDlopen): use NSADDIMAGE_OPTION_WITH_SEARCHING
+	on second NSAddImage only. [Bug 1204237]
+	(TclGuessPackageName): should not be MODULE_SCOPE.
+	(TclpLoadMemory): ppc64 and endian (i386) fixes, add support for
+	loading universal (fat) bundles from memory.
+
+	* unix/tclUnixFCmd.c:
+	* macosx/tclMacOSXFCmd.c: ppc64 and endian (i386) fixes.
+	(TclMacOSXCopyFileAttributes): add support for new Tiger copyfile() API
+	to enable copying of xattrs & ACLs by [file copy].
+
+	* generic/tcl.h: add Darwin specifc configure overrides for TCL_WIDE
+	defines to support fat compiles of ppc and ppc64 at the same time,
+	(replaces Darwin CVS fix by emoy, rdar://3693001). add/correct location
+	of version numbers in macosx files.
+
+	* generic/tclInt.h: clarify fat compile comment.
+
+	* unix/tclUnixPort.h: add Darwin specifc configure overrides to support
+	fat compiles, where configure runs only once for multiple architectures
+	(replaces Darwin CVS fix by emoy, rdar://3693001).
+
+	* macosx/tclMacOSXBundle.c:
+	* macosx/tclMacOSXNotify.c:
+	* unix/tclUnixNotfy.c:
+	* unix/tclUnixPort.h: fix #include order to support compile time
+	override of HAVE_COREFOUNDATION in tclUnixPort.h when building for
+	ppc64
+
+	* macosx/Tcl.pbproj/default.pbxuser (new file):
+	* macosx/Tcl.pbproj/jingham.pbxuser:

+	* macosx/Tcl.xcodeproj/default.pbxuser (new file):
+	* macosx/Tcl.xcodeproj/project.pbxproj (new file): new/updated
+	projects for Xcode 2.2 on 10.4, Xcode 1.5 on 10.3 & ProjectBuilder on
+	10.2, with native tcltest targets and support for universal (fat)
+	compiles.
+
+	* macosx/README: clarification/cleanup, document new Xcode projects and
+	universal (fat) builds via CFLAGS (i.e. all of ppc ppc64 i386 at once).
+
+	* unix/Makefile.in:
+	* unix/aclocal.m4:
+	* unix/configure.in:
+	* unix/dltest/Makefile.in:
+	* macosx/configure.ac (new file): add support for inclusion of
+	unix/configure.in by macosx/configure.ac, allows generation of a config
+	headers enabled configure script in macosx (required by Xcode
+	projects).
+
+	* macosx/GNUmakefile: rename from Makefile to avoid overwriting by
+	configure run in tcl/macosx, add support for reusing configure cache,
+	build target fixes, remove GENERIC_FLAGS override now handled by
+	tcl.m4.
+
+	* generic/tcl.decls: add Tcl_Main declaration as comment to avoid
+	'checkstubs' target complaining about it missing from stubs.
+
+	* generic/regex.h:
+	* generic/tclDate.c:
+	* generic/tclEnv.c:
+	* generic/tclGetDate.y:

+	* generic/tclTrace.c:
+	* generic/tclVar.c:
+	* generic/tommath.h:
+	* tools/fix_tommath_h.tcl:
+	* unix/tclUnixFCmd.c: ensure externally visible symbols not contained
+	in stubs table are declared as MODULE_SCOPE (or as static if not used
+	outside of own source file). These changes allow 'make checkstubs' to
+	complete without error on Darwin with gcc 4.
+
+	* generic/rege_dfa.c (getvacant):
+	* generic/regexec.c (cfind):
+	* generic/tclCompExpr.c (CompileSubExpr):
+	* generic/tclNamesp.c (NamespaceEnsembleCmd):
+	* unix/tclUnixChan.c (TclUnixWaitForFile): initialise variables to
+	silence gcc 4 warnings.
+
+	* generic/tclExecute.c (TclExecuteByteCode): fix unused variable
+	warning when NO_WIDE_TYPE is defined.
+
+	* generic/regguts.h: only #define NDEBUG if not already #defined.
+
+	* unix/tclUnixNotfy.c:
+	* macosx/tclMacOSXNotify.c: sync whitespace & comments.
+
+	* unix/tclUnixPort.h:
+	* win/tclWinPort.h: remove declaration of obsolete&unused TclpMutex
+	API.
+
+	* unix/configure:
+	* unix/tclConfig.h.in: regen.
+
+2005-11-21  Andreas Kupries  <andreask@activestate.com>
+
+	* unix/Makefile.in (install-libraries): Updated Makefile to new
+	* win/Makefile.in (install-libraries):  version of the http package.
+	This fixes the ifneeded/provide mismatch reported when trying to
+	require http. Should we maybe try to automatically extract the version
+	number from the http code to prevent future breakage ?
+
+	This follows the update of the version number by dgp on Nov 15 (No
+	entry found in the ChangeLog).
+
+2005-11-20  Joe English  <jenglish@users.sourceforge.net>
+
+	* generic/tclStubLib.c: Don't set tclStubsPtr to 0 when
+	Tcl_PkgRequireEx() fails [Fix for [Bug 1091431] "Tcl_InitStubs failure
+	crashes wish"]
+
+2005-11-18  Miguel Sofer  <msofer@users.sf.net>
+
+	* tests/trace.test (trace-34.5): [Bug 1047286], added a second test
+	illustrating the role of "ns in callStack" in the ns's visibility
+	during deletion traces.
+
+2005-11-18  Kevin B. Kenny  <kennykb@acm.org>
+
+	* doc/clock.n: Restored several missing lines near the %w format group
+	so that %w and %W are documented with their actual behaviour. [Bug
+	1359183]
+
+2005-11-18  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* generic/tclIO.c (TclFinalizeIOSubsystem): preserve statePtr until we
+	retrieve the next statePtr from it.
+
+2005-11-18  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclObj.c (GetBignumFromObj): replace NULL with
+	tclEmptyStringRep to stop memcpy from complaining in a debug build
+	(the corresponding branch is eliminated by the optimiser otherwise).
+
+2005-11-18  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (TclFinalizeIOSubsystem): Applied Pat Thoyts' patch
+	for [Bug 1359094]. This moves the retrieval of the next channel state
+	to the end of the loop, as the called closeproc may close other
+	channels, i.e. modify the list we are iterating, invalidating any
+	pointer retrieved earlier.
+
+2005-11-18  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclListObj.c:	Restored the SetListFromAny routine to the
+	* generic/tclObj.c:	"list" Tcl_ObjType, and restored the
+	Tcl_RegisterObjType() call for "list". This addresses the needs of some
+	"bridge" extensions to examine whether the Tcl_ObjType of a Tcl_Obj is
+	that of the "list" Tcl_ObjType.
+
+2005-11-18  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* library/http/http.tcl (http::geturl): Improved syntactic validation
+	of URLs, and better error messages in some cases. [Bug 1358369]
+
+2005-11-17  Miguel Sofer  <msofer@users.sf.net>
+
+	* tests/namespace.test: fix comment
+
+2005-11-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStrToD.c:	More data in the "can't happen" Tcl_Panic to
+	aid debugging.
+
+	* generic/tclBasic.c (CallCommandTraces): Save/restore the interp
+	result during traces to fix [Bug 1355342].
+
+2005-11-13  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclInt.h:
+	* generic/tclNamesp.c:
+	* tests/namespace.test: fix for [Bug 1354540] and [Bug 1355942]. The
+	new tests 7.3-6 and the modified 51.13 fail due to the unrelated [Bug
+	1355342]
+
+	* tests/trace.test: added tests 20.13-16 for [Bug 1355342]
+
+2005-11-12  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c (Tcl_DeleteCommandFromToken):
+	* generic/tclObj.c (Tcl_GetCommandFromObj): more partial fixes for
+	[Bug 1354540] - making sure that cached references to a command being
+	deleted cannot be made reusable by a delete trace.
+
+2005-11-12  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclNamesp.c (Tcl_FindCommand): Do not find commands in dead
+	namespaces on the path. Partial fix for [Bug 1354540].
+
+2005-11-11  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclInt.h:	Revised TclParseNumber interface to enable
+	* generic/tclScan.c:	revision to the [scan] command implementation
+	* generic/tclStrToD.c:	to permit tests scan-4.44,55 to pass again.
+	[Bug 1348067].
+
+2005-11-11  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c (Tcl_DeleteCommandFromToken):
+	* generic/tclObj.c (Tcl_GetCommandFromObj): bump the cmd epoch early
+	to insure that cached references to this command are invalidated.
+	Partial fix for [Bug 1352734] - at least insures that namespace-51.13
+	does not cause a panic. The test is still marked as knownbug, pending
+	resolution of what is actually the correct return value ([Bug
+	1354540])
+
+2005-11-09  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclTimer.c: Changed [after] so that it behaves correctly
+	* tests/timer.test:   with negative arguments [Bug 1350293] and
+	arguments that overflow a 32-bit word. [Bug 1350291]

+
+2005-11-08  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclTrace.c (TraceVarEx): Factor out heart of Tcl_TraceVar2
+	(TclTraceVariableObjCmd,TraceVarProc): Use the new internal API to
+	arrange for the clientData to be cleaned up at the same time as the
+	rest of the main trace record. This simplifies the code a bit at the
+	same time.
+
+2005-11-07  Miguel Sofer  <msofer@users.sf.net>
+
+	* tests/trace.test (trace-13.2-4): added tests to detect leak, see [Bug

+	* generic/tclVar.c: fix for [Bug 1334947]. The functions TclPtrSetVar,
+	Tcl_ObjSetVar2 and Tcl_SetVar2Ex now always consume the newValuePtr
+	argument - i.e., they will free a 0-refCount object if they failed to
+	set the variable. Fixed all callers in the core.
+
+2005-11-04  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclGetDate.y: Added abbreviations for the Korean
+	* library/clock.tcl:    timezone. [Patch 1298737]
+	* generic/tclDate.c:    Regenerated.
+
+	* tools/findBadExternals.tcl: Added this script, which locates external
+	symbols that do not begin with 'Tcl' or 'tcl' and hence might be in
+	conflict with other link libraries. Thanks to George Peter Staplin for
+	the idea and the initial version of the script. [Bug 1263012]
+
+	* unix/Makefile.in: Trimmed a bunch of fat out of the tommath/
+	directory in 'make dist'. [RFE 1333318]
+
+	* unix/tcl.m4: Added code to enable [load] on LynxOS. Thanks to

+
+	* tests/expr-old.test (expr-32.52): Use int(.) to restrict result of
+	left shift to the C long range.
+
+	* expr.test (expr-46.13): Added test that illustrates shortcoming of

+
+2005-10-31  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* win/tclWinSerial.c (SerialSetOptionProc): Cleaned up option parsing

+	non-error code paths better.
+	* tests/ioCmd.test (iocmd-8-19): Updated.
+
+2005-10-29  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclTrace.c (TraceVarProc): [Bug 1337229], partial fix. Ensure
+	that a second call with TCL_TRACE_DESTROYED does not lead to a second
+	call to Tcl_EventuallyFree(). It is still true that that second call
+	should not happen, so the bug is not completely fixed.
+	* tests/trace.test (test-18.3-4): added tests for [Bug 1337229] and
+	[Bug 1338280].
+
+2005-10-23  Vince Darley  <vincentdarley@sourceforge.net>

+
+	* generic/tclStrToD.c (RefineApproximation): Plugged a memory leak

+	1334461]. Thanks to Eric Melbardis for the patch.
+
+2005-10-21  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/binary.n: Clarify that virtually all code that uses the 'h'
+	format in [binary scan] should be using the 'H' format instead. It is
+	nearly always a bug to use the other!
+
+2005-10-20  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclListObj.c (TclLsetFlat):
+	* tests/lset.test (lset-10.3): fixed handling of unshared lists with
+	shared sublists, [Bug 1333036] reported by neuronstorm.
+
+2005-10-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclIORChan.c (PassReceivedError,PassReceivedErrorInterp):
+	Fix crash caused by passing -1 as the length to TclNewStringObj(). Only
+	Tcl_NewStringObj (the function call, not the macro) handles that sort
+	of thing correctly. This makes ioCmd.test pass again.
+
+2005-10-19  Don Porter  <dgp@users.sourceforge.net>

+
+2005-10-19  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclIORChan.c: General cleanup, removing checks that are
+	unnecessary due to the general contracts of other functions in the
+	core, converting to using ANSI declarations, etc. Note that nearly the
+	whole file has changed, but it is often just cosmetic.
+
+2005-10-19  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c (INST_DICT_APPEND, INST_DICT_LAPPEND): fixed

+	reported by Aric Bills.
+
+2005-10-18  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Added optimization for I32L64 systems to avoid

+	dramatically in tclbench's matrix.bench.
+
+2005-10-15  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c:	Restored some optimizations of the

+
+2005-10-14  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>
+
+	* generic/tclIO.c (Tcl_ClearChannelHandlers): removed change dated
+	2005-10-04 (see below). Look into [Bug 1323992] for detailed
+	discussion.
+
+	* generic/tcl.h: Fixed bad definition of CRTEXPORT which should have
+	been CRTIMPORT rather. This broke compilation of generic/tclMain.c and
+	was probably introduced by mistake while applying the fix for [Bug
+	1256937] below.
+
+2005-10-14  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclExecute.c (TclIncrObj, TclExecuteByteCode): Tidied up a
+	couple of infelicitous do {...} while(0) constructs.
+
+2005-10-14  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* generic/tcl.h:     Fix for [Bug 1256937] - correctly decorate
+	* generic/tclMain.c: imported functions from msvcrt in static builds.
+
+2005-10-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* tests/format.test: "Forward"-port of test updates relating to [Bug

+
+2005-10-13  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>
+
+	* generic/tclIO.c (Tcl_ClearChannelHandlers): temporary ifdef

+	channel is being closed/cutted.
+
+2005-10-13  Don Porter  <dgp@users.sourceforge.net>

+	parsing "Na". [Bug 1325833]
+
+2005-10-12  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c (GetNumberFromObj):	Restored some lost
+	optimizations for empty string values. We avoid cost of a call to
+	TclParseNumber just to tell us an empty string isn't a number.
+
+2005-10-12  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclPathObj.c (SetFsPathFromAny): TclGetString macro must not

+
+2005-10-12  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclExecute.c (Tcl_ExecuteByteCode, TclIncrObj): Several

+	* generic/tclCompCmds.c: New convenience macro CompileTokens().
+
+2005-10-10  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Corrections to the NO_WIDE_TYPE build. Also
+	added missing "break" to a switch that broke wide XOR operations.
+
+2005-10-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclInterp.c (DeleteScriptLimitCallback)
+	(SetScriptLimitCallback): Improve the interlocking between the script
+	limit callback record and the hash table of current such records, to
+	prevent crashes in callbacks that create callbacks.
+	(Tcl_LimitSetTime): Reset the correct flag. Problem reported by
+	Nicolas Castagne <castagne@imag.fr> on comp.lang.tcl
+
+2005-10-10  Miguel Sofer  <msofer@users.sf.net>

+
+2005-10-07  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]
+
+	* generic/tclExecute.c:	Macro GetNumberFromObj() is version of
+	TclGetNumberFromObj() that saves a function call for common uses.
+
+	* generic/tclInt.h:	Made #undef NO_WIDE_TYPE the default on 32-bit
+	systems. Being able to use 64-bit values without leaping to mp_int
+	should help with performance.
+
+	* generic/tclObj.c:	Bug fixes in the #undef NO_WIDE_TYPE
+	* generic/tclExecute.c:	configuration.
+
+	* generic/tclExecute.c: Improved performance of comparison opcodes and

+
+2005-10-05  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]
+
+	* generic/tclExecute.c: Improved performance of INST_MULT, INST_DIV,

+	from loop" in TclIncrObj() and removed some dead code.
+
+2005-10-05  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclPipe.c (TclCreatePipeline): Fixed [Bug 1109294]. Applied
+	the patch provided by David Gravereaux.

+	Welton's patch for it, and added a note about wideSeekProc.
+
+	* generic/tclIORChan.c (RcClose): Removed unreachable panic/return
+	statements. This fixes the remainder of [Bug 1286256].
+
+2005-10-05  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tests/env.test (env-6.1):
+	* win/tclWinPort.h: define USE_PUTENV_FOR_UNSET 1
+	* generic/tclEnv.c (TclSetEnv, TclUnsetEnv): add USE_PUTENV_FOR_UNSET
+	to existing USE_PUTENV define to account for various systems that have
+	putenv(), but can't unset env vars with it. Note difference between
+	Windows and Linux for actually unsetting the env var (use of '=').
+	Correct the resizing of the environ array. We assume that we are in

+
+2005-10-04  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]
+	* generic/tclExecute.c: Updated TclIncrObj() to more efficiently add

+	INST_UMINUS, INST_UPLUS, INST_BITNOT, and INST_TRY_CVT_TO_NUMERIC
+	sections for performance.
+
+	* generic/tclBasic.c: Updated more callers to make use of
+	TclGetNumberFromObj. Removed some dead code.
+
+2005-10-04  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* win/tclWinSerial.c (SerialSetOptionProc): free argv [Bug 1067708]

+	1311285]
+
+	* generic/tclParse.c (Tcl_ParseCommand): add code that recognizes {} in

+	-DALLOW_EMPTY_EXPAND).
+
+2005-10-04  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>
+
+	* generic/tclIO.c (Tcl_ClearChannelHandlers): now deletes any
+	outstanding timer for the channel. Also, prevents events still in the
+	event queue from triggering on the current channel.
+
+	* generic/tclTimer.c (Tcl_DeleteTimerHandler): bail out early if passed
+	NULL argument.
+
+2005-10-03  Don Porter  <dgp@users.sourceforge.net>

+
+2005-08-17  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclEvent.c (Tcl_Finalize): Removed a copy-and-paste accident
+	that caused a (mostly harmless) double finalize of the load and
+	filesystem subsystems.
+	* tests/clock.test: Eliminated the bad test clock-43.1, and split

+2005-08-17  Kevin Kenny  <kennykb@users.sourceforge.net>
+
+	[kennykb-numerics-branch]
+
+	* generic/tclBasic.c (Tcl_Expr{Long,Double}{,Obj}): Updated to
+	* generic/tclTest.c:                                deal with
+	* tests/expr-old.test:                              bignums (well,
+	* tests/expr.test:                                  mostly).
+	Added a missing "errno=0;" in ExprUnaryFunc so that spurious error
+	returns aren't detected.
+	Added test cases for Tcl_Expr* and Tcl_Expr*Obj because there was very
+	poor test coverage in those areas.
+	* generic/tclParseExpr.c: Reworked parsing of numbers to call
+	TclParseNumber rather than trying to do things locally.
+	* generic/tclStrToD.c: Corrected a comment. Changed so that *endPtrPtr
+	does not include any trailing whitespace.
+
+2005-08-17  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]
+
+	* generic/tclExecute.c: New routine TclIncrObj to centralize the

+	to make use of it.
+
+2005-08-16  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]
+
+	* generic/tclExecute.c:	Made bit shifting opcodes and INST_MOD
+	bignum-aware.
+
+	* tests/scan.test:	Making << bignum-aware means that repeated
+	* tests/string.test:	left shifting cannot turn a positive into a
+	negative. Revised [int_range] and [largest_int] utility commands in the
+	test suite that relied on that happening. Without revision they became
+	infinite loops.
+
+	* generic/tclExecute.c:	Made binary bitwise opcodes bignum-aware.

+2005-08-15  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]	Updates from HEAD.
+	* generic/tclExecute.c:	More revisions to IllegalExprOperandType.
+	Merged INST_BITNOT with INST_UMINUS and make it bignum-aware according

+
+2005-08-13  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]
+
+	* generic/tclObj.c:	Extended Bignum auto-narrowing to auto-narrow
+	to tclWideIntType when appropriate; this helps keep things working as
+	the bytecode execution code is migrated to supporting bignums.
+
+	* generic/tclExecute.c:	Major overhaul of IllegalExprOperandType.
+	Changed several TclNewFooObj() calls to more logically appropriate
+	ones. Added several TODO comments marking opportunies for future work.
+	Made more use of the eePtr->constants. Made INST_UMINUS bignum aware.
+
+2005-08-12  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]
+
+	* generic/tclExecute.c: Simplify doCondJump. Use eePtr->constants as
+	result of INST_DICT_NEXT, INST_LAND, and INST_LOR. Separate INST_LNOT
+	from INST_UMINUS and simplify.
+
+2005-08-12  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclClock.c (MktimeObjCmd):
+	* library/clock.tcl (GetSystemTimeZone, LoadZoneinfoFile)
+	(ReadZoneinfoFile):
+	* tests/clock.test (clock-50.1):
+	Added functionality to read /etc/localtime if it exists, so that Tcl's
+	time can track system time on Linux even if TZ is not set. Changed
+	::tcl::clock::Mktime to check for failure, and added a test case that
+	mimics failure but is really success.
+
+2005-08-11  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]
+
+	* generic/tclExecute.c: Rewrite of INST_LAND/INST_LOR to take advantage
+	of loss of "pure double" issues. Merged INST_UPLUS with
+	INST_TRY_CVT_TO_NUMERIC and updated to use improved rules for impure
+	"double"s as well.
+
+	* generic/tclStrToD.c:	Restored conditional generation of
+	tclWideIntType values by TclParseNumber so that Tcl's not completely
+	broken while bignum calculation support is incomplete. The NO_WIDE_TYPE
+	macro can be used to disable this.
+
+	* generic/tclBasic.c (ExprAbsFunc): First pass making [expr abs(.)]
+	bignum-aware.
+
+2005-08-11  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclEvent.c:         Eliminated the USE_THREAD_STORAGE option
+	* generic/tclInt.h:           (which is on in every build generated by
+	* generic/tclThread.c:        by the standard configurator).
+	* generic/tclThreadStorage.c: Eliminated the code for thread specific
+	* unix/configure:             data without USE_THREAD_STORAGE and
+	* unix/tcl.m4:                radically refactored the code for

+	* unix/tclUnixThrd.c:         dependencies on the order of

+	* win/Makefile.in:            distclean' on Windows clean just a little
+	* win/rules.vc:               bit cleaner.)

+
+2005-08-10  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]
+
+	* generic/tclTomMath.h:	Added mp_shrink, mp_to_unsigned_bin,
+	* unix/Makefile.in:	mp_to_unsigned_bin_n, and mp_unsigned_bin_size
+	* win/Makefile.in:	to routines from libtommath used by Tcl.
+	* win/makefile.vc:
+
+	* generic/tommath.h:	make gentommath_h
+
+	* generic/tclObj.c:	Substantial rewrite to make all number parsing
+	flow through TclParseNumber(). Also established the NO_WIDE_TYPE and
+	BIGNUM_AUTO_NARROW #ifdef's to help track the assumptions of different
+	portions of the code.
+
+	* generic/tclInt.h:	Added NO_WIDE_TYPE #ifdefs
+
+2005-08-10  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclEvent.c (Tcl_Finalize): Pushed Tcl_FinalizeLoad and
+	Tcl_ResetFilesystem down after Tcl_FinalizeThreadAlloc because we can't
+	unload DLL's until after their TSD keys are finalized. (Note that we'll
+	still see aborts if an unloaded DLL has TSD - that still needs to be
+	fixed.
+
+	* tests/compExpr-old.test (compExpr-3.8): Made tests conditional on
+	* tests/expr.test (expr-3.8):             'unix' because they get
+	stack overflows on Win32 threaded builds,
+
+2005-08-09  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclPathObj.c: fix to [file rootname] bug in optimized code

+
+2005-08-08  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]

+
+2005-08-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclThreadStorage.c: Stop exposing the guts of the thread

+
+2005-08-05  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch]

+
+2005-08-05  Donal K. Fellows  <dkf@users.sf.net>
+

+
+2005-08-05  Kevin Kenny  <kennykb@users.sourceforge.net>
+

+	1246264]
+
+	* generic/tclBasic.c (ExprAbsFunc): Added code to handle the corner

+
+2005-08-04  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (CloseChannel): Fixed comment nit, added apparently

+
+2005-08-04  Don Porter  <dgp@users.sourceforge.net>
+
+	[kennykb-numerics-branch] Updated from HEAD
+
+	* generic/tclObj.c:	Rewrote Tcl_GetBooleanFromObj() and supporting

+	number of times a string value must be scanned.
+
+	* generic/tclObj.c:	Simplified routines that manage the typeTable.
+	Deleted the UpdateStringOfBoolean() routine, that can never be called.
+
+2005-08-03  Don Porter  <dgp@users.sourceforge.net>

+
+2005-07-27  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclUtil.c:	Converted the $::tcl_precision value to be kept
+	per-thread to prevent different threads from stomping on each others'
+	formatting prescriptions.
+
+	***POTENTIAL INCOMPATIBILITY*** Multi-threaded programs that set the
+	value of ::tcl_precision will now have to set it in each thread.
+
+	* tests/expr.test:	Consolidated equivalent constraints into

+	* tests/listObj.test:	empty => emptyTest; winOnly => win
+	* tests/obj.test:	intsAre64bit => longIs64bit
+	Also updated some "nonPortable" tests to use constraints that mark
+	precisely what about them isn't portable, so the tests can run where
+	they work.
+
+	* library/init.tcl ([unknown]): Corrected return code handling in the
+	portions of [unknown] that expand incomplete commands during
+	interactive operations. [Bug 1214462].
+
+2005-07-26  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* unix/configure: Regen.

+2005-06-24  Don Porter	<dgp@users.sourceforge.net>
+
+	* library/auto.tcl:	Make file safe to re-[source] without
+	destroying registered auto_mkindex_parser hooks.
+
+2005-06-23  Kevin Kenny  <kennykb@acm.org>
+
+	* win/tclWinChan.c: More rewriting of __asm__ blocks that implement
+	* win/tclWinFCmd.c: SEH in GCC, because mingw's gcc 3.4.2 is not as
+	forgiving of violations committed by the old code and caused panics.
+	[Bug 1225957]
+
+2005-06-23  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tools/tcltk-man2html.tcl: fixed useversion glob pattern to accept
+	multi-digit patchlevels.
+
+2005-06-22  Don Porter	<dgp@users.sourceforge.net>
+
+	* win/tclWinFile.c: Potential buffer overflow. [Bug 1225571] Thanks to
+	Pat Thoyts for discovery and fix.
+
+2005-06-22  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclInt.h:			    Changed the finalization
+	* generic/tclEvent.c (Tcl_Finalize):	    logic to defer the
+	* generic/tclIO.c (TclFinalizeIOSubsystem): shutdown of the pipe
+	* unix/tclUnixPipe.c (TclFinalizePipes):    management until after all
+	* win/tclWinPipe.c (TclFinalizePipes):	    channels have been closed,
+	in order to avoid a situation where the Windows PipeCloseProc2 would
+	re-establish the exit handler after exit handlers had already run,
+	corrupting the heap. [Bug 1225727] Also corrected a potential read of
+	uninitialized memory in PipeClose2Proc [Bug 1225044]
+
+2005-06-21  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclInt.h: Followup to change made on 2005-06-18 by Daniel
+	Steffen. There are compilers (*) who error out on the redefinition of
+	WORDS_BIGENDIAN. We have to undef the previous definition (on the
+	command line) first to make this acceptable. (*): AIX native.
+
+2005-06-21  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclFileName.c: Changed [file split] and [file join] to treat
+	Windows drive letters similarly to ~ syntax and make sure that they
+	appear with "./" in front when they are in intermediate components of
+	the path. [Bug 1194458]
+	* tests/fileName.test: Added test for the above bug.
+
+2005-06-21  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Added missing walk of the list of active
+	* generic/tclTrace.c:	traces to cleanup references to traces being
+	* generic/tclInt.h:	deleted. [Bug 1201035] Made the walk of the
+	* tests/trace.test (trace-34.*): active trace list aware of the
+	direction of trace scanning, so the proper correction can be made.
+	[Bug 1224585]
+
+2005-06-21  Donal K. Fellows  <dkf@users.sf.net>
+
+	* unix/tcl.m4 (SC_ENABLE_SYMBOLS): Only enable the 'compile' special
+	debugging feature when requested in configure.in; removes irrelevant
+	junk from the configure files of extensions that use Tcl's tcl.m4.
+
+2005-06-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompile.h (INST_PUSH_RETURN_OPTIONS): New opcode to allow
+	* generic/tclCompCmds.c (TclCompileCatchCmd):	   compilation of
+	* generic/tclCompile.c:				   TIP#90 catch [Bug
+	* generic/tclExecute.c (TclExecuteByteCode):	   1219112]
+
+	* generic/tclCompCmds.c (TclCompileSwitchCmd): Ensure we spill to the
+	command form in all cases where it generates an error.
+
+2005-06-20  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Generate an error if a mode
+	argument like -exact is passed more than once to the switch command.
+	The previous implementation silently accepted invalid switch
+	invocations like [switch -exact -glob $str ...].
+	* tests/for.test: Check some error cases when invoking continue and
+	break inside a for loop next script.
+	* tests/switch.test: Add checks for shortened version of a mode
+	argument like -exact. Add test for more than one mode argument. Add
+	test for odd case of passing a variable as a body script.
+
+2005-06-18  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclInt.h: ensure WORDS_BIGENDIAN is defined correctly with
+	fat compiles on Darwin (i.e. ppc and i386 at the same time), the
+	configure AC_C_BIGENDIAN check is not sufficient in this case because a
+	single run of the compiler builds for two architectures with different
+	endianness.
+
+	* unix/tcl.m4 (Darwin): add -headerpad_max_install_names to LDFLAGS to
+	ensure we can always relocate binaries with install_name_tool.
+
+	* unix/configure: autoconf-2.59
+
+2005-06-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Fix for [Bug 1154163]; only
+	* tests/format.test: insert 'l' modifier when it is needed.
+
+2005-06-17  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclTimer.c (AfterDelay): Split out the code to manage
+	synchronous-delay [after] commands.
+	* tests/interp.test (interp-34.10): Time limits and synch-delay [after]
+	did not mix well... [Bug 1221395]
+
+2005-06-14  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclBasic.c (Tcl_DeleteCommandFromToken): Only delete a
+	* tests/namespace.test (namespace-49.2): command from the hashtable on
+	reentrant processing if it has not been already deleted; at least three
+	deletes of the same command are possible. [Bug 1220058]
+	* generic/tclTrace.c (TraceCommandProc): Remove bogus error message
+	creation when traces trigger in situations where the command has
+	already been deleted.
+
+2005-06-13  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclFCmd.c: correct fix to file mkdir 2005-06-09 [Bug 1219176]
+
+2005-06-12  Donal K. Fellows  <dkf@users.sf.net>
+

+	for greater clarity.
+
+2005-06-10  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/chan.n: Fold in the descriptive parts of the documentation for
+	all the commands that [chan] builds on top of.
+
+2005-06-09  Vince Darley  <vincentdarley@users.sourceforge.net>
+
+	* generic/tclFCmd.c: fix to race condition in file mkdir [Bug 1217375]

+
+2005-06-09  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/expr.n, doc/mathfunc.n: Fix minor typos [Bug 1211078] and add
+	mention of distinctly-relevant [namespace path] subcommand.
+
+2005-06-07  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclInt.h:		Reduced the Tcl_ObjTypes "index",
+	* generic/tclIndexObj.c:	"ensembleCmd", "localVarName", and
+	* generic/tclNamesp.c:		"levelReference" to file static scope.
+	* generic/tclProc.c:

+
+2005-06-07  Donal K. Fellows  <dkf@users.sf.net>
+

+	* generic/tclIndexObj.c (Tcl_WrongNumArgs):    messages from ensembles
+	* generic/tclIOCmd.c (Tcl_ReadObjCmd):	       can be correct.
+

+	* tests/chan.test (chan-15.2): Added real test of truncation.
+
+2005-06-06  Kevin B. Kenny  <kennykb@acm.org>
+
+	* win/tclWin32Dll.c: Corrected another buglet in the assembly code for
+	stack probing on Win32/gcc. [Bug 1213678]
+	* generic/tclObj,c: Added missing 'static' on definition of
+	UpdateStringOfBignum, and removed a 'switch' on a 'long long' operand
+	(which HP-UX native 'cc' seems unable to handle). [Bug 1215775]
+
+2005-06-04  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	*** 8.5a3 TAGGED FOR RELEASE ***
+
+	* unix/Makefile.in (dist): add libtommath
+
+2005-06-03  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* library/parray.tcl (parray): Only generate the sorted list of element

+
+2005-06-03  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/Makefile: fixed 'embedded' target.

+2005-06-02  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* unix/Makefile.in (html): add BUILD_HTML_FLAGS optional var
+	* tools/tcltk-man2html.tcl: add a --useversion to prevent confusion
+	when multiple Tcl source dirs exist.
+
+2005-06-01  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	For compatibility with earlier Tcl releases,
+	* generic/tclResult.c:	when a command procedure simply does a
+	* generic/tclTest.c:	"return TCL_RETURN;" we must interpret that
+	* tests/result.test:	the same as
+	"return Tcl_SetReturnOptions(interp, Tcl_NewObj());"  [Bug 1209759].
+
+2005-06-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclCompCmds.c (TclCompileSwitchCmd): Allow compilation of
+	-nocase -glob [switch]es (only one we know how to compile).
+
+	TIP#241 IMPLEMENTATION from Joe Mistachkin
+
+	* generic/tclCmdIL.c (Tcl_LsearchObjCmd, Tcl_LsortObjCmd):
+	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Implementation of -nocase
+	option for [lsearch], [lsort] and [switch] commands.
+	* win/tclWinPort.h: Win uses nonstandard function names...

+	* doc/lsearch.n, doc/lsort.n, doc/switch.n: Docs
+
+	* generic/tclCompCmds.c (TclCompileLindexCmd): Compile the most common
+	case of [lindex] more efficiently.
+
+	* unix/tclUnixNotfy.c (Tcl_FinalizeNotifier): Pass the correct number
+	of arguments to Tcl_JoinThread.
+
+2005-05-31  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* unix/configure.in, unix/tcl.m4: Standardize generation of help
+	messages to always use AC_HELP_STRING and always (except for --with-tcl
+	and --with-tk, where the default is complex) say what the default is.
+
+2005-05-31  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>
+
+	* unix/tclUnixNotfy.c: the notifier thread is now created as joinable
+	thread and it is properly joined in Tcl_FinalizeNotifier. This is an

+
+2005-05-30  Zoran Vasiljevic  <vasiljevic@users.sf.net>

+
+	TIP #229 IMPLEMENTATION
+

+
+2005-05-24  Daniel Steffen  <das@users.sourceforge.net>
+

+	* macosx/Tcl-Info.plist.in (new file):
+	* unix/Makefile.in:
+	* unix/configure.in:
+	* unix/tcl.m4:
+	* unix/tclUnixInit.c: moved all Darwin framework build support from
+	macosx/Makefile into the standard unix configure/make buildsystem, the
+	macosx/Makefile is no longer required to build Tcl.framework (but its
+	functionality is still available for backwards compatibility).
+	* unix/configure: autoconf-2.59
+
+	* generic/tclIOUtil.c (TclLoadFile):
+	* generic/tclInt.h:
+	* unix/tcl.m4:
+	* unix/tclLoadDyld.c: added support for [load]ing .bundle binaries in
+	addition to .dylib's: .bundle's can be [unload]ed (unlike .dylib's),
+	and can be [load]ed from memory, e.g. directly from VFS without needing
+	to be written out to a temporary location first. [Bug 1202209]
+	* unix/configure: autoconf-2.59
+	* unix/tclConfig.h.in: autoheader-2.59
+
+	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): change [time] called with a
+	count > 1 to return a string with a float value instead of a rounded
+	off integer. [Bug 1202178]
+
+	* doc/expr.n:
+	* doc/string.n: fixed roff syntax complaints from 'make html'.
+
+2005-05-20  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclParseExpr.c:	Corrected parser to recognize all
+	boolean literals accepted by Tcl_GetBoolean, including prefixes like
+	"y" and "f", and to allow "eq" and "ne" as function names in the proper
+	context. [Bug 1201589].
+
+2005-05-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclBasic.c (TclEvalObjvInternal): Rewrite for greater
+	clarity; although 'goto' is Bad, the contortions you have to go through
+	to avoid it can be worse...
+
+2005-05-19  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier): fixed crashing CFRelease
+	of runLoopSource in Tcl_InitNotifier (reported by Zoran):
+	CFRunLoopAddSource doesn't CFRetain, so can only CFRelease the
+	runLoopSource in Tcl_FinalizeNotifier.
+
+2005-05-18  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (Tcl_ExprBoolean):	Rewrite as wrapper around
+	Tcl_ExprBooleanObj.
+
+	* generic/tclCmdMZ.c ([string is boolean/true/false]): Rewrite dropping
+	string-based Tcl_GetBoolean call, so that internal reps are kept for
+	subsequent quick boolean operations.
+
+	* generic/tclExecute.c:	Dropped most special handling of the "boolean"
+	Tcl_ObjType, since that type should now be rarely encountered.
+
+	* doc/BoolObj.3:	Rewrite of documentation dropping many details
+	about the internals of Tcl_Objs. Shorter documentation focuses on the
+	function and use of the routines.
+
+	* generic/tclInt.h:	Revision to the "boolean" Tcl_ObjType, so that
+	* generic/tclObj.c:	only string values like "yes" and "false" are
+	* tests/obj.test:	kept as the "boolean" Tcl_ObjType. The string
+	values "0" and "1" are kept as "int" Tcl_ObjType, which also produce
+	quick calls to Tcl_GetBooleanFromObj(). Since this internal change
+	means a Tcl_ConvertToType to a "boolean" Tcl_ObjType might not produce
+	a Tcl_Obj of type "boolean", the registration of the "boolean" type is
+	also removed.
+	***POTENTIAL INCOMPATIBILITY***
+	For callers of Tcl_GetObjType on the type name "boolean".
+
+2005-05-17  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclObj.c (TclInitObjSubsystem):	Removed the
+	* tests/listObj.test:	registration of the Tcl_ObjType's "list",
+	* tests/obj.test:	"procbody", "index", "ensembleCommand",
+	"localVarName", and "levelReference". The only reason to register a
+	Tcl_ObjType is to have it returned by Tcl_GetObjType, and the only
+	reason for that is to retrieve a (Tcl_ObjType *) to pass to
+	Tcl_ConvertToType(). None of the types above can support a
+	Tcl_ConvertToType() call; they panic. Better not to offer something
+	than to lead users into a panic.
+	***POTENTIAL INCOMPATIBILITY***
+	For callers of Tcl_GetObjType on the type names listed above.

+2005-05-15  Kevin Kenny  <kennykb@users.sourceforge.net>
+
+	* win/tclWin32Dll.c: conditioned definition of EXCEPTION_REGISTRATION
+	structures on HAVE_NO_SEH, to fix a bug in buildability on MSVC.
+
+2005-05-14  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclInt.decls:
+	* generic/tclTest.c:
+	* generic/tclUtil.c:
+	* win/tclWin32Dll.c: fixed link error due to direct access by tclTest.c
+	to the MODULE_SCOPE tclPlatform global: renamed existing
+	TclWinGetPlatform() accessor to TclGetPlatform() and moved it to
+	generic code so that it can be used by on all platforms where
+	MODULE_SCOPE is enforced.
+
+	* macosx/tclMacOSXBundle.c:
+	* unix/tclUnixInit.c:
+	* unix/tcl.m4 (Darwin): made use of CoreFoundation API configurable and
+	added test of CoreFoundation availablility to allow building on ppc64,
+	replaced HAVE_CFBUNDLE by HAVE_COREFOUNDATION; test for availability of
+	Tiger or later OSSpinLockLock API.
+
+	* unix/tclUnixNotfy.c:
+	* unix/Makefile.in:
+	* macosx/tclMacOSXNotify.c (new file): when CoreFoundation is
+	available, use new CFRunLoop based notifier: allows easy integration
+	with other event loops on Mac OS X, in particular the TkAqua Carbon
+	event loop is now integrated via a standard tcl event source (instead
+	of TkAqua upon loading having to finalize the exsting notifier and
+	replace it with its custom version). [Patch 1202052]
+
+	* tests/unixNotfy.test: don't run unthreaded tests on Darwin since
+	notifier may be using threads even in unthreaded core.
+
+	* unix/tclUnixPort.h:
+	* unix/tcl.m4 (Darwin): test for thread-unsafe realpath during
+	configure, as Darwin 7 and later realpath is threadsafe.
+
+	* macosx/Makefile: enable configure caching.
+
+	* unix/configure.in: wrap tclConfig.h header in #ifndef _TCLCONFIG so
+	that it can be included more than once without warnings from gcc4.0 (as
+	happens e.g. when including both tclInt.h and tclPort.h)
+
+	* macosx/tclMacOSXBundle.c:
+	* unix/tclUnixChan.c:
+	* unix/tclLoadDyld.c:
+	* unix/tclUnixInit.c: fixed gcc 4.0 warnings.
+
+	* unix/configure: autoconf-2.59

+
+	* generic/tclIntDecls.h:

+	* generic/tclStubInit.c: make genstubs
+
+2005-05-13  Kevin Kenny  <kennykb@acm.org>
+
+	* win/tclWin32Dll.c: Further rework of the SEH logic. All
+	EXCEPTION_REGISTRATION records are now in the activation record rather
+	than pushed on the stack.
+
+2005-05-13  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Dropped the TCL_NO_MATH configuration. It's
+	* generic/tclBinary.c:	believed this has not been working in a long

+
+	[kennykb-numerics-branch] Resynchronized with the HEAD; at this

+
+2005-05-11  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclStrToD.c (TclStrToD, RefineResult, ParseNaN): Changed the
+	code to cast 'char' to UCHAR explicitly when using ctype macros, to
+	silence complaints from the Solaris compiler.
+
+2005-05-10  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* unix/tclUnixFCmd.c: add lint attr to enum to satisfy strictly
+	compliant compilers that don't like trailing ,s.
+
+	* tests/string.test: string-10.[21-30]
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): add extra checks to prevent
+	possible UMR in unichar cmp function for string map.
+
+2005-05-10  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclBinary.c (FormatNumber): Fixed a bug where NaN's resulted
+	in reads of uninitialized memory when using 'd', 'q', or 'Q' format.
+	* generic/tclStrToD.c (ParseNaN, TclFormatNaN): Added code to handle
+	the peculiarities of HP's PA_RISC, which uses a different 'quiet' bit
+	in NaN from everyone else.

+
+	The 2005-04-21 changes to Tcl_GetBooleanFromObj were done to bring it
+	into agreement with its docs. Further investigation reveals it was the
+	docs that were incorrect.
+
+	* doc/BoolObj.3:	Corrections to the documentation of
+	Tcl_GetBooleanFromObj to bring it into agreement with what this public
+	interface has always done, including noting the difference in function
+	between Tcl_GetBooleanFromObj and Tcl_GetBoolean.
+
+	* generic/tclGet.c:	Revised Tcl_GetBoolean to no longer be a
+	wrapper around Tcl_GetBooleanFromObj (different function!).
+
+	* generic/tclObj.c:	Removed TclGetTruthValueFromObj routine that
+	was added yesterday. Revisions so that only Tcl_GetBoolean-approved
+	values get the "boolean" Tcl_ObjType. This retains the fix for [Bug
+	1187123].

+
+	* doc/GetInt.3:	Convert argument "string" to "str" to agree with code.
+	Also clarified a few details on int and double formats.
+	* generic/tclGet.c:	Radical code simplification. Converted
+	Tcl_GetFoo() routines into wrappers around Tcl_GetFooFromObj(). Reduces
+	code duplication, and the resulting potential for inconsistency.
+
+	* generic/tclObj.c:	Several changes:
+
+	- Re-ordered error detection code so all values with trailing garbage
+	  receive a "not an integer" message instead of an "integer too large"
+	  message.
+	- Removed inactive code meant to deal with strtoul* routines that fail
+	  to parse leading signs. All of them do, and if any are detected that
+	  do not, the correct fix is replacement with compat/strtoul*.c, not a
+	  lot of special care by the callers.
+	- Tcl_GetDoubleFromObj now avoids shimmering away a "wideInt" intrep.
+	- Fixed Tcl_GetBooleanFromObj to agree with its documentation and with
+	  Tcl_GetBoolean, accepting only "0" and "1" and not other numeric
+	  strings. [Bug 1187123]
+	- Added new private routine TclGetTruthValueFromObj to perform the more
+	  permissive conversion of numeric values to boolean that is needed by
+	  the [expr] machinery.
+
+	* generic/tclInt.h (TclGetTruthValueFromObj):	New routine.
+	* generic/tclExecute.c:	Updated callers to call new routine.
+	* generic/tclBasic.c:	Updated callers to call new routine.
+	* generic/tclCompCmds.c:	Updated callers to call new routine.
+	* generic/tclDictObj.c:	Updated callers to call new routine.
+	* tests/obj.test:	Corrected bad tests that actually expected
+	values like "47" and "0xac" to be accepted as booleans.
+
+	* generic/tclLiteral.c: Disabled the code that forces some literals
+	into the "int" Tcl_ObjType during registration. We can re-enable it if
+	this change causes trouble, but it seems more sensible to let Tcl's
+	"on-demand" shimmering rule, and not try to pre-guess things.

+
+	* generic/tclThreadAlloc.c: modified TclFinalizeThreadAlloc() to
+	explicitly call TclpFreeAllocCache with the NULL-ptr as argument
+	signalling cleanup of private tsd key used only by the threading
+	allocator.
+
+	* unix/tclUnixThrd.c: fixed TclpFreeAllocCache() to recognize when
+	being called with NULL argument. This is a signal for it to clean up
+	the tsd key associated with the threading allocator.
+
+	* win/tclWinThrd.c: renamed TclWinFreeAllocCache to TclpFreeAllocCache
+	and fixed to recognize when being called with NULL argument. This is a

+	<rossc@cisco.com> where [read stdin 1] was grabbing 10 bytes followed
+	by starting a child process that was intended to continue reading from

+
+2005-04-13  Don Porter	<dgp@users.sourceforge.net>
+
+	* unix/tclUnixInit.c (TclpGetEncodingNameFromEnvironment): Reversed

+
+	* generic/tclUtil.c (TclGetProcessGlobalValue):	More robust handling
+	of bad TclInitProcessGlobalValueProc behavior; an immediate panic
+	rather than a mysterious crash later.
+
+	* generic/tclEncoding.c:	Several changes to the way the
+	encodingFileMap cache is maintained. Previously, it was attempted to
+	keep the file map filled and up to date with changes in the encoding
+	search path. This contributed to slow startup times since it required
+	an expensive "glob" operation to fill the cache. Now the validity of
+	items in the cache are checked at the time they are used, so the cache
+	is permitted to fall out of sync with the encoding search path. Only
+	[encoding names] and Tcl_GetEncodingNames() now pay the full expense.

+2007-11-24  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileDictAppendCmd): Fix bug in [dict
+	append] compiler which caused strange stack corruption. [Bug 1837392]
+
+2007-11-23  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIORChan.c: Fixed a problem with reflected channels. 'chan
+	postevent' is defined to work only from within the interpreter
+	containing the handler command. Sensible, we want only handler
+	commands to use it. It identifies the channel by handle. The channel
+	moves to a different interpreter or thread. The interpreter containing
+	the handler command doesn't know the channel any longer. 'chan
+	postevent' fails, not finding the channel any longer. Uhm.
+
+	Fixed by creating a second per-interpreter channel table, just for
+	reflected channels, where each interpreter remembers for which
+	reflected channels it has the handler command. This info does not move
+	with the channel itself. The table is updated by 'chan create', and
+	used by 'chan postevent'.
+
+	* tests/ioCmd.test: Updated the testsuite.
+
+2007-11-23  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* generic/tclVar.c (Tcl_ArrayObjCmd): handle the right data for
+	* tests/var.test (var-14.2):	      [array names $var -glob $ptn]
+
+2007-11-23  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclCmdMZ.c (String*Cmd, TclInitStringCmd): Rebuilt [string]
+	* generic/tclCompCmds.c (TclCompileString*Cmd): as an ensemble.
+
+2007-11-22  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c (Dict*Cmd,TclInitDictCmd): Rebuilt the [dict]
+	* generic/tclCompCmds.c (TclCompileDict*Cmd): command as an ensemble.
+
+2007-11-22  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Rewrote the [string] and
+	* generic/tclDictObj.c (Tcl_DictObjCmd): [dict] implementations to be
+	ready for conversion to ensembles.
+
+	* tests/string.test (string-12.22): Flag shimmering bug found in
+	[string range].
+
+2007-11-21  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileEnsemble): Rewrote the ensemble
+	compiler to remove many of the limitations. Can now compile scripts
+	that use unique prefixes of subcommands, and which have mappings of a
+	command to multiple words (provided the first is a compilable command
+	of course).
+
+2007-11-21  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclNamesp.c (TclMakeEnsemble): Factor out the code to set up
+	a core ensemble from a table of information about subcommands, ready
+	for reuse within the core.
+
+	* generic/various: Start to return more useful Error codes, currently
+	mainly on assorted lookup failures.
+
+2007-11-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c: Changed the underlying implementation of the
+	hash table used in dictionaries to additionally keep all entries in
+	the hash table in a linked list, which is only ever added to at the
+	end. This makes iteration over all entries in the dictionary in
+	key insertion order a trivial operation, and so cleans up a great deal
+	of complexity relating to dictionary representation and stability of
+	iteration order.
+
+	***POTENTIAL INCOMPATIBILITY***
+	For any code that depended on the (strange) old iteration order.
+
+	* generic/tclConfig.c (QueryConfigObjCmd): Correct usage of
+	Tcl_WrongNumArgs.
+
+2007-11-19  Don Porter	<dgp@users.sourceforge.net>

+
+2007-11-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclCmdIL.c (TclInitInfoCmd): Rename the implementation
+	commands for [info] to be something more "expected".
+
+	* generic/tclCompCmds.c (TclCompileInfoExistsCmd): Compiler for the
+	[info exists] subcommand.
+	(TclCompileEnsemble): Cleaned up version of ensemble compiler that was
+	in TclCompileInfoCmd, but which is now much more generally applicable.
+
+	* generic/tclInt.h (ENSEMBLE_COMPILE): Added flag to allow for cleaner
+	turning on and off of ensemble bytecode compilation.
+

+	of arguments passed to command compilers.
+
+2007-11-15  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/regc_nfa.c:	Fixed infinite loop in the regexp compiler.
+	[Bug 1810038]
+
+	* generic/regc_nfa.c:	Corrected looping logic in fixempties() to
+	avoid wasting time walking a list of dead states. [Bug 1832612]
+
+2007-11-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclNamesp.c (NamespaceEnsembleCmd): Must pass a non-NULL

+
+	* doc/re_syntax.n: Try to make this easier to read. It's still a very
+	difficult manual page!
+
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Allow people to turn off the -rpath
+	option to their linker if they so desire. This is a configuration only
+	recommended for (some) vendors. Relates to [Patch 1231022].
+
+2007-11-15  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* win/tclWin32Dll.c: Prefer UINT_PTR to DWORD_PTR when casting
+	pointers to integer types for greater portability. [Bug 1831253]
+
+2007-11-15  Daniel Steffen  <das@users.sourceforge.net>
+

+
+2007-11-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclCompile.c (TclCompileScript): Ensure that we get our

+	to compile a command directly.
+
+	* generic/tclNamesp.c (Tcl_SetEnsembleSubcommandList)
+	(Tcl_SetEnsembleMappingDict):		Special code to make sure that
+	* generic/tclCmdIL.c (TclInitInfoCmd):	[info exists] is compiled
+	right while not allowing changes to the ensemble to cause havok.
+
+	* generic/tclCompCmds.c (TclCompileInfoCmd): Simple compiler for the
+	[info] command that only handles [info exists].
+
+	* generic/tclExecute.c (TclExecuteByteCode:INST_EXIST_*): New
+	instructions to allow the testing of whether a variable exists.
+
+2007-11-14  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/chanio.test: New file. This is essentially a duplicate of
+	'io.test', with all channel commands converted to their 'chan xxx'
+	notation.
+	* tests/io.test: Fixed typo in test description.
+
+2007-11-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/regc*.c: Eliminate multi-char collating element code
+	completely. Simplifies the code quite a bit. If people still want the
+	full code, it will remain on the 8.4 branch. [Bug 1831425]
+
+2007-11-13  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* generic/tclCompCmds.c (TclCompileRegexpCmd): clean up comments, only
+	free dstring on OK from TclReToGlob.
+	(TclCompileSwitchCmd): simplify TclReToGlob usage.
+
+2007-11-14  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/regc*.c: #ifdef/comment out the code that deals with
+	multi-character collating elements, which have never been supported.
+	Cuts the memory consumption of the RE compiler. [Bug 1831425]
+
+2007-11-13  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileSwitchCmd, TclCompileRegexpCmd):
+	Extend [switch] compiler to handle regular expressions as long as
+	things are not too complex. Fix [regexp] compiler so that non-trivial
+	literal regexps get fed to INST_REGEXP.
+
+	* doc/mathop.n: Clarify definitions of some operations.
+
+2007-11-13  Miguel Sofer  <msofer@users.sf.net>
+
+	* unix/tclUnixInit.c: the TCL_NO_STACK_CHECK was being incorrectly
+	undefined here; this should be set (or not) in the compile options, it
+	is used elsewhere and needs to be consistent.
+
+2007-11-13  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* unix/tcl.m4:		Added autoconf goo to detect and make use of
+	* unix/configure.in:	getaddrinfo and friends.
+	* unix/configure:	(regenerated)
+
+2007-11-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* unix/tclUnixCompat.c (TclpGetHostByName): The six-argument form of
+	getaddressbyname_r() uses the fifth argument to indicate whether the
+	lookup succeeded or not on at least one platform. [Bug 1618235]
+
+2007-11-13  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/regcomp.c:	Convert optst() from expensive no-op to a
+	cheap no-op.
+
+2007-11-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* unix/tclUnixChan.c (CreateSocketAddress): Rewrote to use the
+	thread-safe version of gethostbyname() by forward-porting the code
+	used in 8.4, and added rudimentary support for getaddrinfo() (not
+	enabled by default, as no autoconf-ery written). Part of fix for [Bug
+	1618235].
+
+2007-11-12  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* generic/tclGet.c (Tcl_Get, Tcl_GetInt): revert use of TclGet* macros
+	due to compiler warning. These cases won't save time either.
+
+	* generic/tclUtil.c (TclReToGlob): add more comments, set interp
+	result if specified on error.
+
+2007-11-12  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c:		New macro TclResetResult, new iPtr
+	* generic/tclExecute.c:		flag bit INTERP_RESULT_UNCLEAN:
+	* generic/tclInt.h:		shortcut for Tcl_ResetResult for the
+	* generic/tclProc.c:		"normal" case: TCL_OK, no return
+	* generic/tclResult.c:		options, no errorCode nor errorInfo,
+	* generic/tclStubLib.c:		return at normal level. [Patch
+	* generic/tclUtil.c:		1830184]
+
+	THIS PATCH WAS REVERTED: initial (mis)measurements overstated the
+	perfomance wins, which turn out to be tiny. Not worth the
+	complication.

+2007-11-11  Jeff Hobbs	<jeffh@ActiveState.com>

+2007-11-11  Miguel Sofer  <msofer@users.sf.net>
+

+2007-11-10  Miguel Sofer  <msofer@users.sf.net>

+
+	* generic/tclBasic.c:
+	* generic/tclInt.h:
+	* tests/interp.test:
+	* unix/tclUnixInit.c:
+	* win/tclWin32Dll.c: Restore simpler behaviour for stack checking, not
+	adaptive to stack size changes after a thread is launched. Consensus
+	is that "nobody does that", and so it is not worth the cost. Improved
+	failure comments (mistachkin).
+
+2007-11-10  Kevin Kenny	 <kennykb@acm.org>
+
+	* win/tclWin32Dll.c: Rewrote the Windows stack checking algorithm to
+	use information from VirtualQuery to determine the bound of the stack.
+	This change fixes a bug where the guard page of the stack was never
+	restored after an overflow. It also eliminates a nasty piece of
+	assembly code for structured exception handling on mingw. It
+	introduces an assumption that the stack is a single memory arena
+	returned from VirtualAlloc, but the code in MSVCRT makes the same
+	assumption, so it should be fairly safe.
+
+2007-11-10  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c:
+	* generic/tclInt.h:
+	* unix/tclUnixInit.c:
+	* unix/tclUnixPort.h:
+	* win/tclWin32Dll.c: Modify the stack checking algorithm to recheck in
+	case of failure. The working assumptions are now that (a) a thread's
+	stack is never moved, and (b) a thread's stack can grow but not
+	shrink. Port to windows - could be more efficient, but is already
+	cheaper than it was.
+
+2007-11-09  Miguel Sofer  <msofer@users.sf.net>

+	* generic/tclBasic.c:
+	* generic/tclExecute.c:
+	* generic/tclInt.h:
+	* generic/tclUnixInit.c:
+	* generic/tclUnixPort.h: New fields in interp (ekeko!) to cache TSD

+	replace Tcl_AsyncReady and TclpCheckStackSpace by much faster variants
+	[Patch 1829248]
+
+2007-11-09  Jeff Hobbs	<jeffh@ActiveState.com>
+

+						     1827996]
+
+	* generic/tclIO.c (TclGetsObjBinary): Add an efficient binary path for
+					      [gets].
+	(DoWriteChars): Special case for 1-byte channel write.
+
+2007-11-06  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclEncoding.c: Version of the embedded iso8859-1 encoding
+	handler that is faster (functions to do the encoding know exactly what
+	they're doing instead of pulling it from a table, though the table
+	itself has to be retained for use by shift encodings that depend on
+	iso8859-1). [Patch 1826906], committing for dkf.
+
+2007-11-05  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclConfig.c (Tcl_RegisterConfig): Modified to not extend the
+	config database if the encoding provided by the user is not found
+	(venc == NULL). Scripts expecting the data will error out, however we
+	neither crash nor provide bogus information. See [Bug 983509] for more
+	discussion.
+
+	* unix/tclUnixChan.c (TtyGetOptionProc): Accepted [Patch 1823576]
+	provided by Stuart Cassof <stwo@users.sourceforge.net>. The patch adds
+	the necessary utf/external conversions to the handling of the
+	arguments of option -xchar which will allow the use of \0 and similar
+	characters.
+
+2007-11-03  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclTest.c (TestSetCmd2):

+
+	* tools/tcltk-man2html.tcl (output-directive): Convert .DS/.DE pairs

+
+2007-10-28  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclEncoding.c (TclInitEncodingSubsystem): Hard code the
+	iso8859-1 encoding, as it's needed for more than just text (especially
+	binary encodings...) Note that other encodings rely on the encoding
+	being a table encoding (!) so we can't use more efficient encoding

+
+	* generic/tclCompile.c: New bytecode instruction INST_REVERSE to

+
+2007-09-08  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c (DictUpdateCmd, DictWithCmd): Plug a hole that
+	* generic/tclExecute.c (TEBC,INST_DICT_UPDATE_END): allowed a careful
+	* tests/dict.test (dict-21.16,21.17,22.11): attacker to craft a dict

+
+2007-09-07  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclEvent.c ([::tcl::Bgerror]):	Corrections to Tcl's
+	* tests/event.test:	default [interp bgerror] handler so that when

+
+2007-09-07  Miguel Sofer  <msofer@users.sf.net>
+

+
+2007-09-06  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclResult.c (Tcl_GetReturnOptions):	Take care that a
+	* tests/init.test:	non-TCL_ERROR code doesn't cause existing
+	-errorinfo, -errorcode, and -errorline entries to be omitted.
+	* generic/tclEvent.c:	With -errorInfo no longer lost, generate more
+	complete ::errorInfo when calling [bgerror] after a non-TCL_ERROR
+	background exception.
+
+2007-09-06  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclInterp.c (Tcl_Init):	Removed constraint on ability
+	to define a custom [tclInit] before calling Tcl_Init(). Until now the
+	custom command had to be a proc. Now it can be any command.
+
+	* generic/tclInt.decls: New internal routine TclBackgroundException()
+	* generic/tclEvent.c:	that for the first time permits non-TCL_ERROR
+	exceptions to trigger [interp bgerror] handling. Closes a gap in TIP
+	221. When falling back to [bgerror] (which is designed only to handle
+	TCL_ERROR), convert exceptions into errors complaining about the
+	exception.
+
+	* generic/tclInterp.c:	Convert Tcl_BackgroundError() callers to call

+
+2007-09-04  Don Porter	<dgp@users.sourceforge.net>
+
+	* unix/Makefile.in:	It's unreliable to count on the release
+	manager to remember to `make genstubs` before `make dist`. Let the

+
+	* unix/Makefile.in:	Corrections to `make dist` dependencies to be

+
+2007-09-03  Daniel Steffen  <das@users.sourceforge.net>
+

+
+2007-08-27  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Call TclCompileSyntaxError() when

+	longer any need to report TCL_ERROR.
+	* generic/tclCompile.c: Update callers.
+	* generic/tclExecute.c:
+
+	* generic/tclCompCmds.c:	New routine TclCompileSyntaxError()
+	* generic/tclCompile.h: to directly compile bytecodes that report a
+	* generic/tclCompile.c: syntax error, rather than (ab)use a call to
+	TclCompileReturnCmd. Also, undo the most recent commit that papered

+	* generic/tclCompExpr.c:	Register literals found in expressions
+	* tests/compExpr.test:	to restore literal sharing. Preserve numeric
+	intreps when literals are created for the first time. Correct memleak
+	in ExecConstantExprTree() and add test for the leak.
+
+2007-08-24  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCompile.c: replaced copy loop that tripped some compilers
+	with memmove. [Bug 1780870]
+
+2007-08-23  Don Porter	<dgp@users.sourceforge.net>
+
+	* library/init.tcl ([auto_load_index]): Delete stray "]" that created
+	an expr syntax error (masked by a [catch]).
+
+	* generic/tclCompCmds.c (TclCompileReturnCmd):	Added crash protection
+	to handle callers other than TclCompileScript() failing to meet the
+	initialization assumptions of the TIP 280 code in CompileWord().
+
+	* generic/tclCompExpr.c:	Suppress the attempt to convert to
+	numeric when pre-compiling a constant expresion indicates an error.
+
+2007-08-22  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c (TEBC): disable the new shortcut to frequent

+2007-08-21  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclMain.c:	Corrected the logic of dropping the last

+
+2007-08-21  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* tests/thread.test: thread-4.4: clear ::errorInfo in the thread as a

+
+2007-08-20  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c (INST_SUB): fix usage of the new macro for

+
+2007-08-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclExecute.c (Overflowing, TclIncrObj, TclExecuteByteCode):
+	Encapsulate Miguel's last change in a more mnemonic macro.
+
+2007-08-19  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: changed the check for overflow in sums,
+	reducing objsize, number of branches and cache misses (according to
+	cachegrind). Non-overflow for s=a+b:
+	previous
+	  ((a >= 0 || b >= 0 || s < 0) && (s >= 0 || b < 0 || a < 0))

+
+2007-08-16  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclVar.c: improved localVarNameType caching to leverage
+	the new availability of Tcl_Obj in variable names, avoiding string

+
+	* generic/tclExecute.c: check the two most frequent instructions
+	before the switch. Reduces both runtime and obj size a tiny bit.
+
+2007-08-16  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Added a "constant" field to the OpNode
+	struct (again "free" due to alignment requirements) to mark those
+	subexpressions that are completely known at compile time. Enhanced
+	CompileExprTree() and its callers to precompute these constant
+	subexpressions at compile time. This resolves the issue raised in [Bug
+	1564517].

+
+	* generic/tclBasic.c:	Use fully qualified variable names for

+
+2007-08-14  Daniel Steffen  <das@users.sourceforge.net>

+2007-08-10  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Revise CompileExprTree() to use the
+	OpNode mark field scheme of tree traversal. This eliminates the need
+	to use magic values in the left and right fields for that purpose.
+	Also stop abusing the left field within ParseExpr() to store the
+	number of arguments in a parsed function call. CompileExprTree() now
+	determines that for itself at compile time. Then reorder code to
+	eliminate duplication.

+
+	* generic/tclExecute.c: Corrected failure to compile/link in the

+
+2007-08-07  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclInt.h: remove comments refering to VAR_SCALAR, as that
+	flag bit does not exist any longer.
+	* generic/tclProc.c (InitCompiledLocals): removed optimisation for
+	non-resolved case, as the function is never called in that case.
+	Renamed the function to InitResolvedLocals to calrify the point.

+
+	* unix/Makefile.in:	add support for compile flags specific to
+				object files linked directly into executables.
+
+	* unix/configure.in (Darwin): only use -seg1addr flag when prebinding;
+	use -mdynamic-no-pic flag for object files linked directly into exes;

+2007-08-06  Don Porter	<dgp@users.sourceforge.net>
+
+	* tests/parseExpr.test: Update source file name of expr parser code.
+
+	* generic/tclCompExpr.c:	Added a "mark" field to the OpNode
+	struct, which is used to guide tree traversal. This field costs
+	nothing since alignement requirements used the memory already.
+	Rewrote ConvertTreeToTokens() to use the new field, which permitted
+	consolidation of utility routines CopyTokens() and
+	GenerateTokensForLiteral().
+
+2007-08-06  Kevin B. Kenny  <kennykb@users.sf.net>
+
+	* generic/tclGetDate.y: Added a cast to the definition of YYFREE to

+
+	*** POTENTIAL INCOMPATIBILITY *** (tclInt.h and tclCompile.h)
+	Extensions that access internals defined in tclInt.h and/or
+	tclCompile.h may lose both binary and source compatibility. The
+	relevant changes are:
+	1. 'struct Var' is completely changed, all acceses to its internals
+	   (either direct or via the TclSetVar* and TclIsVar* macros) will
+	   malfunction. Var flag values and semantics changed too.
+	2. 'struct Bytecode' has an additional field that has to be
+	   initialised to NULL
+	3. 'struct Namespace' is larger, as the varTable is now one pointer
+	   larger than a Tcl_HashTable. Direct access to its fields will
+	   malfunction.
+	4. 'struct CallFrame' grew one more field (the second such growth with
+	   respect to Tcl8.4).
+	5. API change for the functions TclFindCompiledLocal, TclDeleteVars
+	   and many internal functions in tclVar.c
+
+	Additionally, direct access to variable hash tables via the standard
+	Tcl_Hash* interface is to be considered as deprecated. It still works
+	in the present version, but will be broken by further specialisation
+	of these hash tables. This concerns especially the table of array
+	elements in an array, as well as the varTable field in the Namespace
+	struct.
+
+2007-07-31  Miguel Sofer  <msofer@users.sf.net>
+

+2007-07-31  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+

+	to spoofing. [Bug 681877]
+
+	* unix/tclUnixCompat.c: Simplify the #ifdef logic.

+
+2007-07-30  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* unix/tclUnixChan.c (SET_BITS, CLEAR_BITS): Added macros to make this
+	file clearer.

+2007-07-24  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c (TEOvI, GetCommandSource):
+	* generic/tclExecute.c (TEBC, TclGetSrcInfoForCmd):
+	* generic/tclInt.h:
+	* generic/tclTrace.c (TclCheck(Interp|Execution)Traces):
+	Removed the need for TEBC to inspect the command before calling TEOvI,
+	leveraging the TIP 280 infrastructure. Moved the generation of a
+	correct nul-terminated command string away from the trace code, back
+	into TEOvI/GetCommandSource.
+
+2007-07-20  Andreas Kupries  <andreask@activestate.com>
+
+	* library/platform/platform.tcl: Fixed bug in 'platform::patterns'
+	* library/platform/pkgIndex.tcl: where identifiers not matching
+	* unix/Makefile.in: the special linux and solaris forms would not
+	* win/Makefile.in: get 'tcl' as an acceptable platform added to
+	* doc/platform.n: the result. Bumped package to version 1.0.3 and
+	* doc/platform_shell.n: updated documentation and Makefiles. Also
+	fixed bad version info in the documentation of platform::shell.
+
+2007-07-19  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclParse.c:	In contexts where interp and parsePtr->interp
+	might be different, be sure to use the latter for error reporting.
+	Also pulled the interp argument back out of ParseTokens() since we
+	already had a parsePtr->interp to work with.
+
+2007-07-18  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Removed unused arguments and variables
+
+2007-07-17  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c (ParseExpr):	While adding comments to
+	explain the operations of ParseExpr(), made significant revisions to
+	the code so it would be easier to explain, and in the process made the
+	code simpler and clearer as well.
+
+2007-07-15  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	More commentary.
+	* tests/parseExpr.test:		Several tests of syntax error messages
+	to check that when expression substrings are truncated they leave
+	visible the context relevant to the reported error.
+
+2007-07-12  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Factored out, corrected, and commented
+	common code for reporting syntax errors in LEAF elements.
+
+2007-07-11  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileWhileCmd):
+	* generic/tclCompile.c (TclCompileScript):
+	Corrected faulty avoidance of INST_START_CMD when the first opcode in
+	a script is within a loop (as produced by 'while 1'), so that the
+	corresponding command is properly counted. [Bug 1752146]
+
+2007-07-11  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Added a "parseOnly" flag argument to
+	ParseExpr() to indicate whether the caller is Tcl_ParseExpr(), with an
+	end goal of filling a Tcl_Parse with Tcl_Tokens representing the
+	parsed expression, or TclCompileExpr() with the goal of compiling and
+	executing the expression. In the latter case, more aggressive
+	conversion of QUOTED and BRACED lexeme to literals is done. In the
+	former case, all such conversion is avoided, since Tcl_Token
+	production would revert it anyway. This enables simplifications to the
+	GenerateTokensForLiteral() routine as well.
+
+2007-07-10  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Added a field for operator precedence
+	to be stored directly in the parse tree. There's no memory cost to
+	this addition, since that memory would have been lost to alignment
+	issues anyway. Also, converted precedence definitions and lookup
+	tables to use symbolic constants instead of raw number for improved
+	readability, and continued extending/improving/correcting comments.
+	Removed some unused counter variables. Renamed some variables for
+	clarity and replaced some cryptic logic with more readable macros.
+
+2007-07-09  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Revision so that the END lexeme never
+	gets inserted into the parse tree. Later tree traversal never reaches
+	it since its location in the tree is not variable. Starting and
+	stopping with the START lexeme (node 0) is sufficient. Also finished
+	lexeme code commentary.
+
+	* generic/tclCompExpr.c:	Added missing creation and return of
+	the Tcl_Parse fields that indicate error conditions. [Bug 1749987]
+
+2007-07-05  Don Porter	<dgp@users.sourceforge.net>
+
+	* library/init.tcl (unknown):	Corrected inconsistent error message
+	in interactive [unknown] when empty command is invoked. [Bug 1743676]

+

+	ckfree/ckalloc when the old structs can be reused.
+
+2007-07-04  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclNamesp.c: Fix case where a FQ cmd or ns was being cached

+
+2007-07-03  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Revised #define values so that there
+	is now more expansion room to define more BINARY operators.
+
+2007-07-02  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclHash.c (CompareStringKeys): Always use the strcmp()
+	version; the operation is functionally equivalent, the speed is
+	identical (up to measurement limitations), and yet the code is
+	simpler. [FRQ 951168]
+
+2007-07-02  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tcl.h:	Removed TCL_PRESERVE_BINARY_COMPATIBILITY and
+	* generic/tclHash.c:	any code enabled when it is set to 0. We will
+	* generic/tclStubInit.c:	always want to preserve binary compat
+	of the structs that appear in the interface through the 8.* series of
+	releases, so it's pointless to drag around this never-enabled
+	alternative.
+
+	* generic/tclIO.c:	Removed dead code.
+	* unix/tclUnixChan.c:
+
+	* generic/tclCompExpr.c:	Removed dead code, old implementations
+	* generic/tclEvent.c:	of expr parsing and compiling, including the

+
+2007-06-30  Donal K. Fellows  <dkf@users.sf.net>

+
+2007-06-30  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>
+
+	* generic/tclThread.c: Prevent RemeberSyncObj() from growing the sync

+
+2007-06-29  Donal K. Fellows  <dkf@users.sf.net>

+
+2007-06-29  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclAlloc.c:		on Darwin, ensure memory allocated by

+
+	* generic/tclNamesp.c:	 tweaks to Tcl_GetCommandFromObj and

+
+2007-06-10  Miguel Sofer  <msofer@users.sf.net>

+	traced. INST_INVOKE now calls into this function instead of inlining
+	parts of TEOvI. Same perf, better isolation.
+
+	***POTENTIAL INCOMPAT*** There is a subtle issue with the timing of
+	execution traces that is changed here - first change appeared in my
+	commit of 2007-04-03 [Patch 1693802], which caused some divergence

+
+	* generic/tclExecute.c (INST_INVOKE): isolated two vars to the small
+	block where they are actually used.
+
+	* generic/tclObj.c (Tcl_GetCommandFromObj): rewritten to make the
+	logic clearer; slightly faster too.
+
+	* generic/tclBasic.c:	Split TEOv in two, by separating a processor
+	for non-TCL_OK returns. Also split TEOvI in a full version that
+	handles non-existing and traced commands, and a separate shorter
+	version for the regular case.
+
+	* generic/tclBasic.c:	Moved the generation of command strings for
+	* generic/tclTrace.c:	traces: previously in Tcl_EvalObjv(), now in
+	TclCheck[Interp|Execution]Traces(). Also insured that the strings are
+	properly NUL terminated at the correct length. [Bug 1693986]
+
+	***POTENTIAL INCOMPATIBILITY in internal API***
+	The functions TclCheckInterpTraces() and TclCheckExecutionTraces() (in
+	internal stubs) used to be noops if the command string was NULL, this
+	is not true anymore: if the command string is NULL, they generate an
+	appropriate string from (objc,objv) and use it to call the traces. The
+	caller might as well not call them with a NULL string if he was
+	expecting a noop.
+
+	* generic/tclBasic.c:	Extend usage of TclLimitReady() and
+	* generic/tclExecute.c: (new) TclLimitExceeded() macros.
+	* generic/tclInt.h:

+	mostly in place to enable [info frame] to discover line information in

+
+	* generic/tclInt.h:	Revised the parser so that it never produces

+
+	* generic/tclListObj.c: reverting [Patch 738900] (committed on
+	2007-04-20). Causes some Tk test breakage of unknown importance, but
+	the impact of the patch itself is likely to be so small that it does
+	not warrant investigation at this time.
+
+2007-04-24  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c (DictKeysCmd): Rewrote so that the lock on the

+
+	* generic/tclBinary.c: Addressed several code paths where the error
+	return from the 'binary format' command leaked the result buffer.
+	* generic/tclListObj.c (TclLsetFlat): Fixed a bug where the new list
+	under construction was leaked in the error case. [Bug 1705778, leaks
+	K13 and K14]
+
+2007-04-24  Jeff Hobbs	<jeffh@ActiveState.com>

+	* unix/Makefile.in (dist): add platform library package to src dist
+
+2007-04-24  Don Porter	<dgp@users.sourceforge.net>

+
+2007-04-23  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclCompCmds.c (TclCompileUpvarCmd): Plugged a memory leak in

+	* generic/tclTest.c (Testregexpobjcmd): Removed an invalid access
+	beyond the end of 'objv' in 'testregexp -about'.
+	All of these issues reported under [Bug 1705778] - detected with the

+
+2007-04-22  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclVar.c (TclDeleteNamespaceVars): fixed access to freed

+
+2007-04-20  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclListObj.c (SetListFromAny): avoid discarding internal

+
+2007-04-20  Kevin B. Kenny  <kennykb@acm.org>
+
+	* doc/clock.n: Corrected a silly error (transposed 'uppercase' and
+	'lowercase' in clock.n. [Bug 1656002]
+	Clarified that [clock scan] does not recognize a locale's alternative
+	calendar.
+	Deleted an entirely superfluous (and also incorrect) remark about the
+	effect of Daylight Saving Time on relative times in [clock scan]. [Bug
+	1582951]
+	* library/clock.tcl: Corrected an error in skipping over the %Ey field
+	on input.
+	* library/msgs/ja.msg:
+	* tools/loadICU.tcl: Corrected several localisation faults in the

+	* generic/tclPathObj.c: Corrected a 'const'ness fault that caused
+	bitter complaints from MSVC.
+	* tests/clock.test (clock-40.1, clock-58.1, clock-59.1): Corrected a
+	test case that depended on ":localtime" being able to handle dates
+	prior to the Posix epoch. [Bug 1618445] Added a test case for the
+	dates of the Japanese emperors. [Bug 1637471] Added a regression test
+	for military time zone input conversion. [Bug 1586828]
+	* generic/tclGetDate.y (MilitaryTable): Fixed an ancient bug where the

+	compiler.
+
+2007-04-18  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c (INST_LSHIFT): fixed a mistake introduced in
+	version 1.266 ('=' became '=='), which effectively turned the block
+	that handles native shifts into dead code. This explains why the
+	testsuite did not pick this mistake. Rewrote to make the intention
+	clear.
+
+	* generic/tclInt.h (TclDecrRefCount): change the order of the
+	branches, use empty 'if ; else' to handle use in unbraced outer
+	if/else conditions (as already done in tcl.h)
+
+	* generic/tclExecute.c: slight changes in Tcl_Obj management.
+
+2007-04-17  Kevin B. Kenny  <kennykb@acm.org>

+	matching of keywords.
+
+2007-04-14  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: removed some code at INST_EXPAND_SKTOP that
+	duplicates functionality already present at checkForCatch.
+
+2007-04-12  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: new macros OBJ_AT_TOS, OBJ_UNDER_TOS,
+	OBJ_AT_DEPTH(n) and CURR_DEPTH that remove all direct references to

+	cleanupV_pushObjResultPtr).
+
+2007-04-11  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCompCmds.c: moved all exceptDepth management to the

+
+2007-04-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclInt.h (TclNewLiteralStringObj): New macro to make
+	allocating literal string objects (i.e. objects whose value is a
+	constant string) easier and more efficient, by allowing the omission
+	of the length argument. Based on [Patch 1529526] (afredd)
+	* generic/*.c: Make use of this (in many files).
+
+2007-04-08  Miguel Sofer  <msofer@users.sf.net>

+
+2007-04-03  Don Porter	<dgp@users.sourceforge.net>

+
+	* generic/tclCompile.c (TclCompileScript, TclPrintInstruction):
+	* generic/tclExecute.c (TclExecuteByteCode): Changed the definition of
+	INST_START_CMD so that it knows how many commands start at the current
+	location. This makes the interpreter command counter correct without
+	requiring a large number of instructions to be issued. (See my change
+	from 2007-01-19 for what triggered this.)
+
+2007-03-30  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompile.c:
+	* generic/tclCompExpr.c:

+
+	* generic/tclProc.c (Tcl_ApplyObjCmd):
+	* tests/apply.test (9.3): Fixed Tcl_Obj leak on error return; an

+	return path.
+
+2007-03-28  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c (STR_REVERSE):	Implement the actual [string

+
+	* generic/tclInt.h (TclStringObjReverse):	New internal routine

+2007-03-27  Don Porter	<dgp@users.sourceforge.net>
+

+	TclStackAlloc calls.
+
+2007-03-24  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>
+
+	* win/tclWinThrd.c: Thread exit handler marks the current thread as
+	un-initialized. This allows exit handlers that are registered later to
+	re-initialize this subsystem in case they need to use some sync
+	primitives (cond variables) from this file again.
+
+2007-03-23  Miguel Sofer  <msofer@users.sf.net>

+
+2007-03-22  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdAH.c (Tcl_ForeachObjCmd):	Replaced arrays on the
+	C stack and ckalloc calls with TclStackAlloc calls to use memory on
+	Tcl's evaluation stack.
+
+	* generic/tclExecute.c: Revised GrowEvaluationStack to take an
+	argument specifying the growth required by the caller, so that a
+	single reallocation / copy is the most that will ever be needed even
+	when required growth is large.
+
+2007-03-21  Don Porter	<dgp@users.sourceforge.net>

+	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Handle tricky case with loss
+	* tests/cmdIL.test (cmdIL-1.29):	of list rep during sorting due
+	to shimmering. [Bug 1675116]
+
+2007-03-09  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl (ReadZoneinfoFile): Added Y2038 compliance to the
+	code for version-2 'zoneinfo' files.
+	* tests/clock.test (clock-56.3): Added a test case for Y2038 and
+	'zoneinfo'. Modified test initialisation to use the
+	'loadTestedCommands' function of tcltest to bring in the correct path
+	for the registry library.
+
+2007-03-08  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclListObj.c (TclLsetList):	Rewrite so that the routine
+	itself does not do any direct intrep surgery. Better isolates those

+
+2007-03-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclListObj.c (TclLindexList, TclLindexFlat): Moved these

+	equivalent functions for [lset]'s guts are arranged.
+
+2007-03-08  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl: Further tweaks to the Windows time zone table
+	(restoring missing Mexican time zones). Added rudimentary handling of
+	version-2 'zoneinfo' files. Update US DST rules so that zones such as
+	'EST5EDT' get the correct transition dates.
+	* tests/clock.test: Added rudimentary test cases for 'zoneinfo'
+	parsing. Adjusted several tests that depended on obsolete US DST
+	transition rules.
+
+2007-03-07  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/tclMacOSXNotify.c: add spinlock debugging and sanity checks.

+
+2007-03-07  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdIL.c (TclLindex*):	Rewrites to make efficient
+	private copies of the list and indexlist arguments, so we can operate
+	on the list elements directly with no fear of shimmering effects.
+	Replaces defensive coding schemes that are otherwise required. End
+	result is that TclLindexList is entirely a wrapper around
+	TclLindexFlat, which is now the core engine of all [lindex]
+	operations.
+
+	* generic/tclObj.c (Tcl_AppendAllObjTypes):	Converted to simpler

+2007-03-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclRegexp.c (TclRegAbout): Generate information about a

+
+2007-03-07  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl: Adjusted Windows time zone table to handle new US

+
+2007-03-03  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclLink.c (LinkedVar): Added macro to conceal at least some
+	of the pointer hackery.
+
+2007-03-02  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdIL.c (Tcl_LreverseObjCmd):	Added missing

+	of an unshared "list" Tcl_Obj. [Bug 1672585]
+
+	* generic/tclCmdIL.c (Tcl_JoinObjCmd):	Revised [join] implementation
+	to append Tcl_Obj's instead of strings. [RFE 1669420]
+
+	* generic/tclCmdIL.c (Info*Cmd):	Code simplifications and
+	optimizations.
+
+2007-03-02  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclCompile.c (TclPrintInstruction): Added a scheme to allow
+	* generic/tclCompile.h (AuxDataPrintProc):    aux-data to be printed
+	* generic/tclCompCmds.c (Print*Info):	      out for debugging. For
+	this to work, immediate operands referring to aux-data must be
+	identified as such in the instruction descriptor table using
+	OPERAND_AUX4 (all are always 4 bytes).
+
+	* generic/tclExecute.c (TclExecuteByteCode): Rewrote the compiled
+	* generic/tclCompCmds.c (TclCompileDictCmd): [dict update] so that it
+	* generic/tclCompile.h (DictUpdateInfo):     stores critical

+
+	* generic/tclCmdIL.c (Tcl_LrangeObjCmd):	Rewrite in the same

+	list elements directly with no fear of shimmering effects. Replaces
+	defensive coding schemes that are otherwise required.
+
+	* generic/tclCmdAH.c (Tcl_ForeachObjCmd):	Rewrite to make

+2007-03-01  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclCompCmds.c (TclCompileForeachCmd): Prevent an unexpected

+
+2007-02-26  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIORChan.c (FreeReflectedChannel): Added the missing
+	refcount release between NewRC and FreeRC for the channel handle

+
+2007-02-26  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdAH.c (Tcl_ForeachObjCmd):	Removed surplus
+	copying of the objv array that used to be a workaround for [Bug
+	404865]. That bug is long fixed.
+
+2007-02-24  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Use new interface in Tcl_EvalObjEx so that the
+	recounting logic of the List internal rep need not be repeated there.
+	Better encapsulation of internal details.
+
+	* generic/tclInt.h:	New internal routine TclListObjCopy() used
+	* generic/tclListObj.c: to efficiently do the equivalent of [lrange
+	$list 0 end]. After some experience with this, might be a good
+	candidate for exposure as a public interface. It's useful for callers
+	of Tcl_ListObjGetElements() who want to control the ongoing validity
+	of the returned objv pointer.
+
+2007-02-22  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/pkg.test: Added tests for the case of an alpha package
+	satisfying a require for the regular package, demonstrating a corner

+
+2007-02-13  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tools/fix_tommath_h.tcl: Further tweaking for the x86-64. The change
+	is to make 'mp_digit' be an 'unsigned int' on that platform; since
+	we're using only 32 bits of it, there's no reason to make it a 64-bit

+
+	* tools/fix_tommath_h.tcl: Added code to patch out a check for

+	mp_word type. Tetra-int's simply fail on too many gcc-glibc-OS
+	combinations to be ready for shipment today, even if they work for

+2007-01-25  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tcl.m4: integrate CPPFLAGS into CFLAGS as late as possible and

+
+2007-01-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclCompile.c (TclCompileScript): Reduce the frequency with

+
+2007-01-19  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/tclMacOSXFCmd.c (TclMacOSXSetFileAttribute): on some versions

+
+	* tests/mathop.test:	Commmitted several new tests from Peter Spjuth

+
+2006-12-03  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Added expr parsing routines that

+2006-10-31  Don Porter	<dgp@users.sourceforge.net>
+

+	* generic/tclCmdIL.c:	TclAppendPrintfToObj, TclAppendFormatToObj,

+	* generic/tclDictObj.c: intent of making the latter list, plus
+	* generic/tclExecute.c: TclAppendLimitedToObj and
+	* generic/tclIORChan.c: TclAppendObjToErrorInfo, public via a revised

+2006-10-31  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c, generic/tcl.h, generic/tclInterp.c:
+	* generic/tclNamesp.c: removing the flag bit TCL_EVAL_NOREWRITE, the
+	last remnant of the callObjc/v fiasco. It is not needed, as it is now
+	always set and checked or'ed with TCL_EVAL_INVOKE.
+
+2006-10-31  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* win/rules.vc: Fix for [Bug 1582769] - options conflict with VC2003.
+
+2006-10-31  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclBasic.c, generic/tclNamesp.c, generic/tclProc.c:
+	* generic/tclInt.h: Removed the callObjc and callObjv fields from the
+	Interp structure. They did not function correctly and made other parts
+	of the core amazingly complex, resulting in a substantive change to
+	[info level] behaviour. [Bug 1587618]
+	* library/clock.tcl: Removed use of [info level 0] for calculating the
+	command name as used by the user and replace with a literal. What's
+	there now is sucky, but at least appears to be right to most users.
+	* tests/namespace.test (namespace-42.7,namespace-47.1): Reverted
+	changes to these tests.
+	* tests/info.test (info-9.11,info-9.12): Added knownBug constraint
+	since these tests require a different behaviour of [info level] than
+	is possible because of other dependencies.
+
+2006-10-30  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* tools/tcltk-man2html.tcl (option-toc): handle any kind of options
+	defined toc section (needed for ttk docs)
+
+2006-10-30  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c (TEOVI): insured that the interp's callObjc/v
+	fields are restored after traces run, as they be spoiled. This was
+	causing a segfault in tcllib's profiler tests.
+
+2006-10-30  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c (INST_MOD): Corrected improper testing of the
+	* tests/expr.test:		   sign of bignums when applying Tcl's
+	division rules. Thanks to Peter Spjuth. [Bug 1585704]
+
+2006-10-29  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclNamesp.c (EnsembleImplementationCmd):
+	* tests/namespace.test (47.7-8): reverted a wrong "optimisation" that
+	completely broke snit; added two tests.
+
+2006-10-28  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclProc.c (ObjInterpProcEx, TclObjInterpProcCore): Split the
+	core of procedures to make it easier to build procedure-like code
+	without going through horrible contortions. This is the last critical
+	component to make advanced OO systems workable as simple loadable
+	extensions. TOIPC is now in the internal stub table.
+	(MakeProcError, MakeLambdaError): Refactored ProcessProcResultCode to
+	be simpler, some of which goes to TclObjInterpProcCore, and the rest
+	of which is now in these far simpler routines which just do errorInfo
+	stack generation for different types of procedure-like entity.
+	* tests/apply.test (apply-5.1): Updated to expect the more informative
+	form of message.
+
+2006-10-27  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclVar.c (HasLocalVars): New macro to make various bits and
+	pieces cleaner.
+
+	* generic/tclNamesp.c (TclSetNsPath): Expose SetNsPath() through
+	internal stubs table with semi-external name.
+
+	* generic/tclInt.h (CallFrame): Add a field for handling context data
+	for extensions (like object systems) that should be tied to a call
+	frame (and not a command or interpreter).
+
+	* generic/tclBasic.c (TclRenameCommand): Change to take CONST args;
+	they were only ever used in a constant way anyway, so this appears to
+	be a spot that was missed during TIP#27 work.
+
+2006-10-26  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclProc.c (SetLambdaFromAny): minor change, eliminate
+	redundant call to Tcl_GetString (thanks aku).
+
+	* generic/tclInterp.c (ApplyObjCmd):
+	* generic/tclNamesp.c (EnsembleImplementationCmd): replaced ckalloc
+	(heap) with TclStackAlloc (execution stack).
+
+2006-10-24  Miguel Sofer  <msofer@users.sf.net>
+
+	* tests/info.test (info-9.11-12): tests for [Bug 1577492]
+	* tests/apply.test (apply-4.3-5): tests for [Bug 1574835]
+
+	* generic/tclProc.c (ObjInterpProcEx): disable itcl hacks for calls
+	from ApplyObjCmd (islambda==1), as they mess apply's error messages
+	[Bug 1583266]
+
+2006-10-23  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclProc.c (ApplyObjCmd): fix wrong#args for apply by using
+	the ensemble rewrite engine. [Bug 1574835]
+	* generic/tclInterp.c (AliasObjCmd): previous commit missed usage of
+	TCL_EVAL_NOREWRITE for aliases.
+
+	* generic/tclBasic.c (TclEvalObjvInternal): removed redundant check
+	for ensembles. [Bug 1577628]
+
+	* library/clock.tcl (format, scan): corrected wrong # args messages to
+	* tests/clock.test (3.1, 34.1):	    make use of the new rewrite
+	capabilities of [info level]
+
+	* generic/tcl.h:	   Lets TEOV update the iPtr->callObj[cv] new
+	* generic/tclBasic.c:	   fields, except when the flag bit
+	* generic/tclInt.h:	   TCL_EVAL_NOREWRITE is present. These values
+	* generic/tclNamesp.c:	   are used by Tcl_PushCallFrame to initialise
+	* generic/tclProc.c:	   the frame's obj[cv] fields, and allows
+	* tests/namespace.test:	   [info level] to know and use ensemble
+	rewrites. [Bug 1577492]
+
+	***POTENTIAL INCOMPATIBILITY***
+	The return value from [info level 0] on interp alias calls is changed:
+	previously returned the target command (including curried values), now
+	returns the source - what was actually called.
+
+2006-10-23  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tcl.h:	   Modified the Tcl call stack so there is
+	* generic/tclBasic.c:	   always a valid CallFrame, even at level 0
+	* generic/tclCmdIL.c:	   [Patch 1577278]. Most of the changes
+	* generic/tclInt.h:	   involve removing tests for a NULL
+	* generic/tclNamesp.c:	   iPtr->(var)framePtr. There is now a
+	* generic/tclObj.c:	   CallFrame pushed at interp creation with a
+	* generic/tclProc.c:	   pointer to it stored in iPtr->rootFramePtr.
+	* generic/tclTrace.c:	   A second unused field in Interp is
+	* generic/tclVar.c:	   hijacked to enable further functionality,
+	currently unused (but with several FRQs depending on it).
+
+	***POTENTIAL INCOMPATIBILITY***
+	Any user that includes tclInt.h and needs to determine if it is
+	running at level 0 should change (iPtr->varFramePtr == NULL) to
+	(iPtr->varFramePtr == iPtr->rootFramePtr).

+2006-10-21  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tcl.h, generic/tclHash.c: Tcl_FindHashEntry now calls
+	Tcl_CreateHashEntry with a newPtr set to NULL: this would have caused
+	a segfault previously and eliminates duplicated code. A macro has been
+	added to tcl.h (only used when TCL_PRESERVE_BINARY_COMPATABALITY is
+	not set - i.e., not by default).
+
+2006-10-20  Reinhard Max  <max@tclers.tk>
+
+	* unix/configure.in: Added autodetection for OS-supplied timezone

+
+2006-10-16  Miguel Sofer  <msofer@users.sf.net>
+

+	found by mjanssen.
+
+2006-10-16  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclBasic.c: Moved TIP#219 cleanup to DeleteInterpProc.
+
+2006-10-16  Daniel Steffen  <das@users.sourceforge.net>
+
+	* changes: updates for 8.5a5 release.
+
+	* unix/tclUnixThrd.c (TclpThreadGetStackSize): Darwin: fix for main
+	thread, where pthread_get_stacksize_np() returns incorrect info.
+
+	* macosx/GNUmakefile: don't redo prebinding of non-prebound binaires.
+
+2006-10-16  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclPkg.c (ExactRequirement):	Plugged memory leak. Also
+	changed Tcl_Alloc()/Tcl_Free() calls to ckalloc()/ckfree() for easier
+	memory debugging in the future. [Bug 1568373]
+
+	* library/tcltest/tcltest.tcl:	Revise tcltest bump to 2.3a1.
+	* library/tcltest/pkgIndex.tcl: This permits more features to be
+	* unix/Makefile.in:	added to tcltest before we reach version 2.3.0
+	* win/Makefile.in:	best timed to match the release of Tcl 8.5.0.
+	* win/makefile.vc:	This also serves as a demo of TIP 268 features
+
+2006-10-13  Colin McCormack <coldstore@users.sf.net>
+
+	* win/tclWinFile.c: corrected erroneous attempt to protect against
+	NULL return from Tcl_FSGetNormalizedPath per [Bug 1548263] causing
+	[Bug 1575837].
+	* win/tclWinFile.c: alfredd supplied patch to fix [Bug 1575837]
+
+2006-10-13  Daniel Steffen  <das@users.sourceforge.net>
+

+2006-10-12  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclInterp.c (ApplyObjCmd):
+	* tests/interp.test (interp-14.5-10): made [interp alias] use the

+	1576006]
+
+2006-10-12  David Gravereaux <davygrvy@pobox.com>
+
+	* win/nmakehlp.c: Replaced all wnsprintf() calls with snprintf().
+	wnsprintf was not in my shwlapi header file (VC++6)
+
+2006-10-11  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclPkg.c (Tcl_PackageRequireEx):	Corrected crash when
+	argument version=NULL passed in.
+
+2006-10-10  Don Porter	<dgp@users.sourceforge.net>
+
+	* changes:	Updates for 8.5a5 release.
+
+	* generic/tclNamespace.c (TclTeardownNamespace):  After the
+	commandPathSourceList of a namespace is cleared, set the
+	commandPathSourceList to NULL so we don't try to walk the list a
+	second time, possibly after it is freed. [Bug 1566526]
+	* tests/namespace.test (namespace-51.16):	Added test.
+
+2006-10-09  Miguel Sofer  <msofer@users.sf.net>
+
+	* doc/UpVar.3: brough the docs in accordance to the code. Ever since
+	8.0, Tcl_UpVar(2)? accepts TCL_NAMESPACE_ONLY as a flag value, and
+	var-3.4 tests for proper behaviour. The docs only allowed 0 and
+	TCL_GLOBAL_ONLY. [Bug 1574099]
+
+2006-10-09  Miguel Sofer  <msofer@users.sf.net>
+
+	* tests/*.test: updated all tests to refer explicitly to the global
+	variables ::errorInfo, ::errorCode, ::env and ::tcl_platform: many
+	were relying on the alternative lookup in the global namespace, that
+	feature is tested specifically in namespace and variable tests.
+
+	The modified testfiles are: apply.test, basic.test, case.test,
+	cmdIL.test, cmdMZ.test, compExpr-old.test, error.test, eval.test,

+	1512138]
+
+	* generic/tclCompile.c:
+	* generic/tclHistory.c:

+
+2006-09-28  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclPkg.c (CompareVersions): Bugfix. Check string lengths
+	* tests/pkg.test: before comparison. The shorter string is the smaller
+	number. Added testcases as well. Interestingly all existing test cases
+	for vcompare compared numbers of the same length with each other. [Bug
+	1563836]
+
+2006-09-28  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclIO.c (Tcl_GetsObj): added two test'n'panic guards for

+
+2006-09-27  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Corrected error in INST_LSHIFT in the
+	* tests/expr.test:	calculation done to determine whether a shift
+	in the (long int) type is possible. The calculation had literal value
+	"1" where it needed a value "1L" to compute the correct result. Error

+
+	* generic/tclPkg.c (CompareVersion):	Flatten strcmp() results to
+	{-1, 0, 1} to match expectations of CompareVersion() callers.
+
+2006-09-27  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/regc_color.c (singleton):
+	* generic/regc_cvec.c (addmcce):
+	* generic/regcomp.c (compile, dovec): the static function addmcce does
+	nothing when called with two NULL pointers; the only call is by
+	compile with two NULL pointers (regcomp.c #includes regc_cvec.c).
+	Large parts (all?) the code for mcce (multi character collating
+	element) that we do not use is ifdef'ed out with the macro
+	REGEXP_MCCE_ENABLE.
+	This silences coverity bugs 7, 16, 80
+
+	* generic/regc_color.c (uncolorchain):
+	* generic/regc_nfa.c (freearc): changed tests and asserts to
+	equivalent formulation, designed to avoid an explicit comparison to
+	NULL and satisfy coverity that 6 and 9 are not bugs.
+
+2006-09-27  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/pkg.test: Added test for version comparison at the 32bit
+	boundary. [Bug 1563836]
+
+	* generic/tclPkg.c: Rewrote CompareVersion to perform string
+	comparison instead of numeric. This breaks through the 32bit limit on
+	version numbers. See code for details (handling of leading zeros,
+	signs, etc.). un-CONSTed some arguments of CompareVersions,
+	RequirementSatisfied, and AllRequirementsSatisfied. The new compare
+	modifies the string (temporary string terminators). All callers use
+	heap-allocated ver-intreps, so we are good with that. [Bug 1563836]
+
+2006-09-27  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclFileName.c (TclGlob): added a panic for a call with
+	TCL_GLOBMODE_TAILS and pathPrefix==NULL. This would cause a segfault,
+	as found by coverity #26.
+
+2006-09-26  Kevin B. Kenny  <kennykb@acm.org>
+
+	* doc/Encoding.3:	 Added covariant 'const' qualifier for the
+	* generic/tcl.decls:	 Tcl_EncodingType argument to
+	* generic/tclEncoding.c: Tcl_CreateEncoding. [Further TIP#27 work.]
+	* generic/tclDecls.h:	 Reran 'make genstubs'.
+
+2006-09-26  Pat Thoyts	<patthoyts@users.sourceforge.net>

+	* win/rules.vc:
+
+2006-09-26  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tcl.h:	As 2006-09-22 commit from Donal K. Fellows
+	demonstrates, "#define NULL 0" is just wrong, and as a quotable chat
+	figure observed, "If NULL isn't defined, we're not using a C compiler"
+	Improper fallback definition of NULL removed.
+
+2006-09-25  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* generic/tcl.h:	More fixing which struct stat to refer to.
+	* generic/tclGetDate.y: Some casts from time_t to int required.
+	* generic/tclTimer.c:	Tcl_Time structure members are longs.
+	* win/makefile.vc:	Support for varying compiler options
+	* win/rules.vc:		and build to platform-specific subdirs.
+
+2006-09-25  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (Tcl_StackChannel): Fixed [Bug 1564642], aka

+
+2006-09-25  Andreas Kupries  <andreask@activestate.com>

+2006-09-25  Kevin B. Kenny   <kennykb@acm.org>
+
+	* generic/tclNotify.c (Tcl_DeleteEvents): Simplified the code in hopes

+
+2006-09-25  Donal K. Fellows  <dkf@users.sf.net>

+2006-09-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclThreadTest.c (TclCreateThread): Use NULL instead of 0 as

+
+2006-09-21  Don Porter	<dgp@users.sourceforge.net>
+

+2006-09-19  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c (INST_EXPON):	Native type overflow detection

+	* unix/configure: Regenerated, using autoconf 2.59
+
+	* unix/tclUnixCompat.c (PadBuffer): Fixed bug in calculation of the

+
+2006-09-11  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* win/rules.vc:	   Updated to install http, tcltest and msgcat as

+
+	* unix/Makefile.in:	Bumped msgcat version to 1.4.2 to be

+
+	* library/msgcat/msgcat.tcl (msgcat::Init): on Darwin, add fallback of
+	* tests/msgcat.test:			    default msgcat locale to
+	* unix/tclUnixInit.c (TclpSetVariables):    current CFLocale
+	identifier if available (via private ::tcl::mac::locale global, set at
+	interp init when on Mac OS X 10.3 or later with CoreFoundation).
+
+	* library/tcltest/tcltest.tcl: add 'line' verbose level: prints source
+	* doc/tcltest.n:	       file line information of failing tests.
+
+	* macosx/Tcl.xcodeproj/project.pbxproj: add new tclUnixCompat.c file;
+	revise tests target to use new tcltest 'line' verbose level.

+
+2006-09-08  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>
+
+	* unix/tclUnixCompat.c: Added fallback to gethostbyname() and
+	gethostbyaddr() if the implementation is known to be MT-safe
+	(currently for Darwin 6 or later only).
+
+	* unix/configure.in: Assume gethostbyname() and gethostbyaddr() are

+
+2006-09-07  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>
+
+	* unix/tclUnixCompat.c: Added fallback to MT-unsafe library calls if

+	Fixed alignment of arrays copied by CopyArray() to be on the
+	sizeof(char *) boundary.
+
+2006-09-07  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

+
+2006-09-04  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* doc/package.n: correct package example
+
+2006-08-31  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Corrected flawed logic for disabling
+	the INST_TRY_CVT_TO_NUMERIC instruction at the end of an expression
+	when function arguments contain operators. [Bug 1541274]
+
+	* tests/expr-old.test:	The remaining failing tests reported in
+	* tests/expr.test:	[Bug 1381715] are all new in Tcl 8.5, so
+	there's really no issue of compatibility with Tcl 8.4 result to deal
+	with. Fixed by updating tests to expect 8.5 results.
+
+2006-08-29  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclParseExpr.c:	Dropped the old expr parser.
+

+
+	* generic/tclIOGT.c (ExecuteCallback):
+	* generic/tclPkg.c (Tcl_PkgRequireEx): replace Tcl_GlobalEval(Obj)
+	with more efficient Tcl_Eval(Obj)Ex
+
+	* unix/Makefile.in (valgrindshell): add valgrindshell target and
+	update default VALGRINDARGS. User can override, or add to it with
+	VALGRIND_OPTS env var.
+
+	* generic/tclFileName.c (DoGlob): match incrs with decrs.
+
+2006-08-29  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclParseExpr.c:	Use the "parent" field of orphan
+	ExprNodes to store the closure of left pointers. This lets us avoid
+	repeated re-scanning leftward for the left boundary of subexpressions,
+	which in worst case led to near O(N^2) runtime.
+
+2006-08-29  Joe Mistachkin  <joe@mistachkin.com>
+
+	* unix/tclUnixInit.c: Fixed the issue (typo) that was causing

+	FreeBSD (and possibly other Unix platforms).
+
+2006-08-29  Colin McCormack  <coldstore@users.sourceforge.net>
+
+	* generic/tclIOUtil.c:	Added test for NULL return from

+2006-08-28  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclStringObj.c:	Revised ObjPrintfVA to take care to
+	* generic/tclParseExpr.c:	copy only whole characters when doing
+	%s formatting. This relieves callers of TclObjPrintf() and
+	TclFormatToErrorInfo() from needing to fix arguments to character
+	boundaries. Tcl_ParseExpr() simplified by taking advantage. [Bug
+	1547786]
+
+	* generic/tclStringObj.c:	Corrected TclFormatObj's failure to
+	count up the number of arguments required by examining the format
+	string. [Bug 1547681]
+
+2006-08-27  Joe Mistachkin  <joe@mistachkin.com>

+	Duquette.
+
+2006-08-24  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/tzdata: Regenerated, including several new files, from
+	Olson's tzdata2006j.
+	* library/clock.tcl:
+	* tests/clock.test: Removed an early testing hack that allowed loading
+	'registry' from the build tree rather than an installed one. This is a
+	workaround for [Bug 15232730], which remains open because it's a
+	symptom of a deeper underlying problem.
+
+2006-08-23  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclParseExpr.c:	Minimal collection of new tests
+	* tests/parseExpr.test:		testing the error messages of the new
+	expr parser. Several bug fixes and code simplifications that appeared
+	during that effort.
+
+2006-08-21  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIOUtil.c:	Revisions to complete the thread finalization
+	of the cwdPathPtr. [Bug 1536142]
+
+	* generic/tclParseExpr.c:	Revised mistaken call to
+	TclCheckBadOctal(), so both [expr 08] and [expr 08z] have same
+	additional info in error message.
+
+	* tests/compExpr-old.test:	Update existing tests to not fail with

+	msys build is possible.
+
+2006-08-21  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/tclMacOSXNotify.c (Tcl_WaitForEvent): if the run loop is
+	already running (e.g. if Tcl_WaitForEvent was called recursively),
+	re-run it in a custom run loop mode containing only the source for the
+	notifier thread, otherwise wakeups from other sources added to the
+	common run loop modes might get lost.
+
+	* unix/tclUnixNotfy.c (Tcl_WaitForEvent): on 64-bit Darwin,
+	pthread_cond_timedwait() appears to have a bug that causes it to wait
+	forever when passed an absolute time which has already been exceeded
+	by the system time; as a workaround, when given a very brief timeout,
+	just do a poll on that platform. [Bug 1457797]
+
+	* generic/tclClock.c (ClockClicksObjCmd): add support for Darwin

+
+2006-08-18  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tcl.m4 (Darwin): add support for --enable-64bit on x86_64, for
+	universal builds including x86_64, for 64-bit CoreFoundation on
+	Leopard and for use of -mmacosx-version-min instead of
+	MACOSX_DEPLOYMENT_TARGET
+	* unix/configure: autoconf-2.59
+	* unix/tclConfig.h.in: autoheader-2.59
+
+	* generic/tcl.h:	  add fixes for building on Leopard and
+	* unix/tclUnixPort.h:	  support for 64-bit CoreFoundation on Leopard
+	* macosx/tclMacOSXFCmd.c:
+
+	* unix/tclUnixPort.h: on Darwin x86_64, disable use of vfork as it
+	causes execve to fail intermittently. (rdar://4685553)
+
+	* generic/tclTomMath.h: on Darwin 64-bit, for now disable use of
+	128-bit arithmetic through __attribute__ ((mode(TI))), as it leads to
+	link errors due to missing fallbacks. (rdar://4685527)
+
+	* macosx/Tcl.xcodeproj/project.pbxproj: add x86_64 to universal build,
+	switch native release targets to use DWARF with dSYM, Xcode 3.0
+	changes
+	* macosx/README: updates for x86_64 and Xcode 2.4.
+
+	* macosx/Tcl.xcodeproj/default.pbxuser: add test suite target that
+	* macosx/Tcl.xcodeproj/project.pbxproj: runs the tcl test suite at
+	build time and shows clickable test suite errors in the GUI build
+	window.
+
+	* tests/macOSXFCmd.test: fix use of deprecated resource fork paths.
+
+	* unix/tclUnixInit.c (TclpInitLibraryPath): move code that is only
+	needed when TCL_LIBRARY is defined to run only in that case.
+
+	* generic/tclLink.c (LinkTraceProc): fix 64-bit signed-with-unsigned
+	comparison warning from gcc4 -Wextra.
+
+	* unix/tclUnixChan.c (TclUnixWaitForFile): with timeout < 0, if
+	select() returns early (e.g. due to a signal), call it again instead
+	of returning a timeout result. Fixes intermittent event-13.8 failures.
+
+2006-08-17  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompile.c:		Revised the new set of expression

+	* generic/*.c, macosx/tclMacOSXNotify.c, unix/tclUnixNotfy.c,
+	* win/tclWinThrd.c: Tidy up invokations of Tcl_Panic() to promote

+	* generic/tclBasic.c (Tcl_CreateInterp): More efficient handling of
+	* generic/tclClock.c (TclClockInit):	 registration of commands not

+
+2006-08-03  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tclUnixPipe.c (TclpCreateProcess): for USE_VFORK: ensure
+	standard channels are initialized before vfork() so that the child
+	doesn't potentially corrupt global state in the parent's address space
+
+	* tests/compExpr-old.test: add 'oldExprParser' constraint to all tests
+	* tests/compExpr.test:	   that depend on the exact format of the
+	* tests/compile.test:	   error messages of the pre-2006-07-05
+	* tests/expr-old.test:	   expression parser. The constraint is on by
+	* tests/expr.test:	   default (i.e those tests still fail), but
+	* tests/for.test:	   can be turned off by passing '-constraints
+	* tests/if.test:	   newExprParser' to tcltest, which will skip
+	* tests/parseExpr.test:	   the 196 failing tests in the testsuite that
+	* tests/while.test:	   are caused by the new expression parser
+	error messages.
+
+2006-07-31  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclClock.c (ConvertLocalToUTCUsingC): Corrected a regression
+	that caused dates before 1969 to be one day off in the :localtime time
+	zone if TZ is not set. [Bug 1531530]
+
+2006-07-30  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclClock.c (GetJulianDayFromEraYearMonthDay): Corrected
+	several errors in converting dates before the Common Era [Bug 1426279]
+	* library/clock.tcl: Corrected syntax errors in generated code for %EC
+	%Ey, and %W format groups [Bug 1505383]. Corrected a bug in cache
+	management for format strings containing [glob] metacharacters [Bug
+	1494664]. Corrected several errors in formatting/scanning of years
+	prior to the Common Era, and added the missing %EE format group to
+	indicate the era.
+	* tools/makeTestCases.tcl: Added code to make sure that %U and %V
+	format groups are included in the tests. (The code depends on %U and
+	%V formatting working correctly when 'makeTestCases.tcl' is run,
+	rather than making a completely independent check.) Added tests for
+	[glob] metacharacters in strings. Added tests for years prior to the
+	Common Era.
+	* tests/clock.test: Rebuilt with new test cases for all the above.

+
+2006-07-24  Don Porter	<dgp@users.sourceforge.net>

+
+2006-07-20  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier, Tcl_WaitForEvent):
+	create notifier thread lazily upon first call to Tcl_WaitForEvent()
+	rather than in Tcl_InitNotifier(). Allows calling exeve() in processes
+	where the event loop has not yet been run (Darwin's execve() fails in
+	processes with more than one thread), in particular allows embedders
+	to call fork() followed by execve(), previously the pthread_atfork()
+	child handler's call to Tcl_InitNotifier() would immediately recreate
+	the notifier thread in the child after a fork.
+
+	* macosx/tclMacOSXFCmd.c (TclMacOSXCopyFileAttributes):	   add support
+	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier):		   for weakly
+	* unix/tclUnixInit.c (Tcl_GetEncodingNameFromEnvironment): importing

+						extra warnings.
+	* macosx/README: document how to enable weak-linking; cleanup.
+	* unix/tclUnixPort.h: add support for weak-linking; conditionalize
+	AvailabilityMacros.h inclusion; only disable realpath on 10.2 or
+	earlier when threads are enabled.
+	* unix/tclLoadDyld.c (TclpLoadMemoryGetBuffer): change runtime Darwin
+	* unix/tclUnixInit.c (TclpInitPlatform):	release check to use

+
+2006-07-13  Andreas Kupries <andreask@activestate.com>
+
+	* unix/tclUnixPort.h: Added the inclusion of <AvailabilityMacros.h>.
+	The missing header caused the upcoming #if conditions to wrongly
+	exclude realpath, causing file normalize to ignore symbolic links in
+	the path.
+
+2006-07-11  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>
+
+	* generic/tclAsync.c: Made Tcl_AsyncDelete() more tolerant when called
+	after all thread TSD has been garbage-collected.
+
+2006-07-05  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclParseExpr.c:	Completely new expression parser that
+	builds a parse tree instead of operating with deep recursion. This
+	corrects reports of stack-blowing crashes parsing long expressions
+	[Bug 906201] and replaces a fundamentally O(N^2) algorithm with an
+	O(N) one [RFE 903765]. The new parser is better able to generate error
+	messages that clearly report both the nature and context of the syntax
+	error [Bugs 1029267, 1381715]. For now, the code for the old parser is
+	still present and can be activated with a "#define OLD_EXPR_PARSER
+	1". This is for the sake of a clean implementation patch, and for ease
+	of benchmarking. The new parser is non-recursive, so much lighter in
+	stack consumption, but it does use more heap, so there may be cases
+	where parsing of long expressions that succeeded with the old parser
+	will lead to out of memory panics with the new one. There are still
+	more improvements possible on that point, though significant progress
+	may require changes to the Tcl_Token specifications documented for the
+	public Tcl_Parse*() routines.
+	***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the exact
+	(usually terrible) error messages generated by the old parser. This
+	includes a large number of tests in the test suite.
+
+	* generic/tclInt.h:		Replaced TclParseWhiteSpace() with
+	* generic/tclParse.c:		TclParseAllWhiteSpace() which is what
+	* generic/tclParseExpr.c:	all the callers really needed.
+	Breaking whitespace runs at newlines is useful only to the command
+	parsing function, and it can call the file scoped routine
+	ParseWhiteSpace() to do that.
+
+	* tests/expr-old.test:	Removed knownBug constraints that masked
+	* tests/expr.test:	failures due to revised error messages.
+	* tests/parseExpr.test:
+
+2006-06-20  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIOUtil.c:	Changed default configuration to
+	* generic/tclInt.decls: #undef USE_OBSOLETE_FS_HOOKS which disables
+	* generic/tclTest.c:	access to the Tcl 8.3 internal routines for
+	hooking into filesystem operations. Everyone ought to have migrated to
+	Tcl_Filesystems by now.
+	***POTENTIAL INCOMPATIBILITY*** for any code still stuck in the
+	pre-Tcl_Filesystem era.
+
+	* generic/tclIntDecls.h:	make genstubs
+	* generic/tclStubInit.c:
+
+	* generic/tclStrToD.c:	Removed dead code that permitted disabling of
+	recognition of the new 0b and 0o numeric formats.
+
+	* generic/tclExecute.c: Removed dead code that implemented alternative
+	* generic/tclObj.c:	design where numeric values did not
+	automatically narrow to the smallest Tcl_ObjType required to hold them
+
+	* generic/tclCmdAH.c:	Removed dead code that was old implementation
+	of [format].
+
+2006-06-14  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tclUnixPort.h (Darwin): support MAC_OS_X_VERSION_MAX_ALLOWED
+	define from AvailabilityMacros.h: override configure detection and
+	only use API available in the indicated OS version or earlier.
+
+2006-06-14  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* doc/format.n, doc/scan.n: Added examples for converting between
+	characters and their numeric interpretations following user prompting.
+
+2006-06-13  Donal K. Fellows  <dkf@users.sf.net>
+
+	* unix/tclLoadDl.c (TclpDlopen): Workaround for a compiler bug in Sun
+	Forte 6. [Bug 1503729]
+
+2006-06-06  Don Porter	<dgp@users.sourceforge.net>
+
+	* doc/GetStdChan.3:	Added recommendation that each call to
+	Tcl_SetStdChannel() be accompanied by a call to Tcl_RegisterChannel().
+
+2006-06-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* doc/Alloc.3: Added documentation of promise that Tcl_Realloc(NULL,x)
+	is the same as Tcl_Alloc(x), as discussed in comp.lang.tcl. Also fixed
+	nonsense sentence to say something meaningful.
+
+2006-05-29  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* generic/tcl.h (Tcl_DecrRefCount): use if/else construct to allow
+	placement in unbraced outer if/else conditions. (jcw)
+
+2006-05-27  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/tclMacOSXNotify.c: implemented pthread_atfork() handler that
+	* unix/tcl.m4 (Darwin):	    recreates CoreFoundation state and
+	notifier thread in the child after a fork(). Note that pthread_atfork
+	is available starting with Tiger only. Because vfork() is used by the
+	core on Darwin, [exec]/[open] are not affected by this fix, only
+	extensions or embedders that call fork() directly (such as TclX).
+	However, this only makes fork() safe from corefoundation tcl with
+	--disable-threads; as on all platforms, forked children may deadlock
+	in threaded tcl due to the potential for stale locked mutexes in the
+	child. [Patch 923072]
+
+	* unix/configure: autoconf-2.59
+	* unix/tclConfig.h.in: autoheader-2.59
+
+2006-05-24  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* unix/tcl.m4 (SC_CONFIG_SYSTEM): Fixed quoting of command script to
+	awk; it was a rarely used branch, but it was wrong. [Bug 1494160]
+
+2006-05-23  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* doc/chan.n, doc/refchan.n: Tighten up the documentation to follow a
+	slightly more consistent style with regard to argument capitalization.
+
+2006-05-13  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclProc.c (ProcCompileProc): When a bump of the compile
+	epoch forces the re-compile of a proc body, take care not to overwrite
+	any Proc struct that may be referred to on the active call stack. Note
+	that the fix will not be effective for code that calls the private
+	routine TclProcCompileProc() directly. [Bug 1482718]
+
+2006-05-13  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclEvent.c (HandleBgErrors): fix leak. [Coverity issue 86]
+
+2006-05-05  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclMain.c (Tcl_Main):		Corrected flaw that required
+	* tests/main.test: (Tcl_Main-4.5):	processing of one interactive
+	command before passing control to the loop routine registered with
+	Tcl_SetMainLoop(). [Bug 1481986]

+
+	* generic/tclStrToD.c: Added code to support the "middle endian"
+	floating point format used in the Nokia N770's software-based floating
+	point. Thanks to Bruce Johnson for reporting this bug, originally on
+	http://wiki.tcl.tk/15408.
+	* library/clock.tcl: Fixed a bug with Daylight Saving Time and Posix
+	time zone specifiers reported by Martin Lemburg in
+	http://groups.google.com/group/comp.lang.tcl/browse_thread/thread/9a8b15a4dfc0b7a0

+	readiness for reinitialization.
+
+2006-04-06  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct):	It seems there
+	* tests/indexObj.test:	are extensions that rely on the prior behavior
+	* doc/GetIndex.3:	that the empty string cannot succeed as a
+	unique prefix matcher, so I'm restoring Donal Fellows's solution.
+	Added mention of this detail to the documentation. [Bug 1464039]

+
+2006-04-05  Don Porter	<dgp@users.sourceforge.net>
+
+	* win/tclWinInit.c:	More careful calls to Tcl_DStringSetLength()

+2006-04-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): Allow empty
+	strings to be matched by the Tcl_GetIndexFromObj machinery, in the
+	same manner as any other key. [Bug 1464039]
+
+2006-04-03  Andreas Kupries <andreask@activestate.com>
+
+	* generic/tclIO.c (ReadChars): Added check, panic and commentary to a
+	piece of code which relies on BUFFER_PADDING to create enough space at
+	the beginning of each buffer for the insertion of partial multibyte
+	data at the beginning of a buffer. Commentary explains why this code
+	is OK, and the panic is as a precaution if someone twiddled the
+	BUFFER_PADDING into uselessness.
+
+	* generic/tclIO.c (ReadChars): Temporarily suppress the use of
+	TCL_ENCODING_END set when EOF was reached while the buffer we are
+	converting is not truly the last buffer in the queue. Together with
+	the Utf bug below it was possible to completely wreck the buffer data
+	structures, eventually crashing Tcl. [Bug 1462248]
+
+	* generic/tclEncoding.c (UtfToUtfProc): Stop accessing memory beyond
+	the end of the input buffer when TCL_ENCODING_END is set and the last
+	bytes of the buffer start a multi-byte sequence. This bug contributed
+	to [Bug 1462248].
+
+2006-03-30  Miguel Sofer  <msofer@users.sf.net>
+

+2006-03-28  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* win/tclWinPipe.c (TclpCreateProcess): change panics to Tcl errors
+	and do proper refcounting of noe objPtr. [Bug 1194429]

+
+2006-03-28  Daniel Steffen  <das@users.sourceforge.net>

+
+2006-03-27  Andreas Kupries <andreask@activestate.com>
+
+	* doc/CrtChannel.3:    Added TCL_CHANNEL_VERSION_5, made it the
+	* generic/tcl.h:       version where the "truncateProc" is defined at,
+	* generic/tclIO.c:     and moved all channel drivers of Tcl to v5.

+
+2006-03-27  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Merge INST_MOD computation in with the
+	INST_?SHIFT instructions, which also operate only on two integral
+	values. Also corrected flaw that made INST_BITNOT of wide values
+	require mp_int calculations. Also corrected type that missed optimized
+	handling of the tclBooleanType by the TclGetBooleanFromObj macro.
+
+	* changes:	Updates for another RC.
+
+2006-03-25  Don Porter	<dgp@users.sourceforge.net>

+	overflow to use mp_int calculations.
+
+2006-03-24  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclExecute.c (TclExecuteByteCode): Added a couple of missing
+	casts to 'int' that were affecting compilablity on VC6.
+
+2006-03-24  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclEncoding.c: Reverted latest change [Bug 506653] since it
+	reportedly killed test performance on Windows.
+
+	* generic/tclExecute.c: Revised INST_EXPON implementation to do
+	calculations in native types as much as possible, moving to mp_ints
+	only when necessary.
+
+2006-03-23  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Merged INST_EXPON handling in with the other
+	binary operators that operate on all number types (INST_ADD, etc.).
+
+	* tests/env.test: With case preserved (see 2006-03-21 commit) be sure
+	to do case-insensitive filtering. [Bug 1457065]
+
+2006-03-23  Reinhard Max  <max@suse.de>
+
+	* unix/tcl.spec: Cleaned up and completed the spec file. An RPM can

+	<tarball>"
+
+2006-03-22  Reinhard Max  <max@suse.de>
+
+	* tests/stack.test: Run the stack tests in subshells, so that they are
+	reported as failed tests rather than bugs in the test suite if the
+	recursion causes a segfault.
+
+2006-03-21  Don Porter	<dgp@users.sourceforge.net>
+

+	* generic/tclIntPlatDecls.h:
+	* generic/tclStubInit.c: make genstubs
+
+2006-03-20  Andreas Kupries <andreask@activestate.com>
+
+	* win/Makefile.in (install-libraries): Generate tcl8/8.4 directory
+	under Windows as well (cygwin Makefile). Related entry: 2006-03-07,
+	dgp. This moved the installation of http from 8.2 to 8.4, partially. A
+	fix of the required directory creation was done for unix on Mar 10,
+	without entry in the Changelog. This entry is for the fix of the
+	directory creation under Windows.
+
+	* unix/installManPage: There is always one even more broken "sed".
+	Moved the # comment starting character in the sed script to the
+	beginning of their respective lines. The AIX sed will not recognize
+	them as comments otherwise :( The actual text stays indented for
+	better association with the commands they belong to.

+2006-03-18  Vince Darley  <vincentdarley@sourceforge.net>
+
+	* generic/tclFileName.c:
+	* doc/FileSystem.3:
+	* tests/fileName.test: Fix to [Bug 1084705] so that 'glob -nocomplain'
+	finally agrees with its documentation and doesn't swallow genuine
+	errors.
+
+	***POTENTIAL INCOMPATIBILITY*** for scripts that assumed '-nocomplain'
+	removes the need for 'catch' to deal with non-understood path names.

+	* generic/tclIOUtil.c (TclGetOpenMode): Added the flag O_APPEND to the
+	list of POSIX modes used when opening a file for 'a'ppend. This
+	enables the proper automatic seek-to-end-on-write by the OS. See [Bug
+	680143] for longer discussion.
+
+	* tests/ioCmd.test (iocmd-13.7.*): Extended the testsuite to check the
+	new handling of 'a'.
+
+2006-03-15  Andreas Kupries <andreask@activestate.com>
+
+	* tests/socket.test: Extended the timeout in socket-11.11 from 10 to
+	40 seconds to allow for really slow machines. Also extended
+	actual/expected results with value of variable 'done' to make it
+	clearer when a test fails due to a timeout. [Bug 792159]
+
+2006-03-15  Vince Darley  <vincentdarley@sourceforge.net>
+
+	* win/fCmd.test: add proper test constraints so the new tests don't
+	run on Unix.
+
+2006-03-14  Andreas Kupries <andreask@activestate.com>
+
+	* generic/tclPipe.c (TclCreatePipeline): Modified the processing of
+	pipebars to fail if the last bar is followed only by redirections.
+	[Bug 768659]
+
+2006-03-14  Andreas Kupries <andreask@activestate.com>
+
+	* doc/fconfigure.n: Clarified that -translation is binary is reported
+	as lf when queried, because it is identical to lf, except for the
+	special additional behaviour when setting it. [Bug 666770]
+
+2006-03-14  Andreas Kupries <andreask@activestate.com>
+
+	* doc/clock.n: Removed double-quotes around section title NAME; not
+	needed.
+	* unix/installManpage: Reverted part to handle double-quotes in
+	section NAME, chokes older sed installations.
+
+2006-03-14  Andreas Kupries <andreask@activestate.com>
+
+	* library/tm.tcl (::tcl::tm::Defaults): Fixed handling of environment
+	variable TCLX.y_TM_PATH, bad variable reference. Thanks to Julian
+	Noble. [Bug 1448251]
+
+2006-03-14  Vince Darley  <vincentdarley@sourceforge.net>
+
+	* win/tclWinFile.c: updated patch to deal with 'file writable' issues
+	on Windows XP/2000.
+	* generic/tclTest.c:
+	* unix/tclUnixTest.c:
+	* win/tclWinTest.c:
+	* tests/fCmd.test: updated test suite to deal with correct permissions
+	setting and differences between XP/2000 and 95/98 3 tests still fail;
+	to be dealt with shortly
+
+2006-03-13  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclEncoding.c: Report error when an escape encoding is
+	missing one of its sub-encodings. [Bug 506653]
+
+	* unix/configure.in:	Revert change from 2005-07-26 that sometimes
+	* unix/configure:	added $prefix/share to the tcl_pkgPath. See
+	[Patch 1231015]. autoconf-2.59.
+
+2006-03-10  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclProc.c (ObjInterpProcEx):
+	* tests/apply.test (apply-5.1): Fix [apply] error messages so that
+	they quote the lambda expression. [Bug 1447355]
+
+2006-03-10  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>
+
+	-- Summary of changes fixing [Bug 1437595] --
+
+	* generic/tclEvent.c: Cosmetic touches and identation
+	* generic/tclInt.h: Added TclpFinalizeSockets() call.
+
+	* generic/tclIO.c: Calls TclpFinalizeSockets() as part of the
+	TclFinalizeIOSubsystem().
+
+	* unix/tclUnixSock.c: Added no-op TclpFinalizeSockets().
+
+	* win/tclWinPipe.c, win/tclWinSock.c: Finalization of sockets/pipes is
+	now solely done in TclpFinalizeSockets() and TclpFinalizePipes() and
+	not over the thread-exit handler, because the order of actions the Tcl
+	generic core will impose may result in cores/hangs if the thread exit
+	handler tears down corresponding subsystem(s) too early.
+
+2006-03-10  Vince Darley  <vincentdarley@sourceforge.net>
+
+	* win/tclWinFile.c: previous patch breaks tests, so removed.
+
+2006-03-09  Vince Darley  <vincentdarley@sourceforge.net>
+

+
+	* changes:	Update in prep. for 8.5a4 release.
+
+	* unix/Makefile.in:	Package http 2.5.2 requires Tcl 8.4, so the
+	* win/Makefile.in:	*.tm installation has to be placed in an "8.4"
+	directory, not an "8.2" directory.
+
+2006-03-06  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Revised handling of TCL_EVAL_* flags to

+
+2006-03-03  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclPathObj.c: Revised yesterday's fix for [Bug 1379287] to
+	work on Windows.
+
+	* generic/tclObj.c:	Compatibility support for existing code that
+	calls Tcl_GetObjType("boolean").
+
+2006-03-02  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclPathObj.c:		Fix for failed normalization of paths
+	* tests/fileSystem.test:	with /../ that lead back to the root
+	of the filesystem, like /foo/.. [Bug 1379287]
+
+2006-03-01  Reinhard Max  <max@suse.de>
+
+	* unix/installManPage: Fix the script for manpages that have quotes
+	around the .SH arguments, as doctools produces them. [Bug 1292145]
+	Some minor cleanups and improvements.
+
+2006-02-28  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Corrections to be sure that TCL_EVAL_GLOBAL
+	* tests/namespace.test: evaluations act the same as [uplevel #0]
+	* tests/parse.test:	evaluations, even when execution traces or
+	* tests/trace.test:	invocations of [::unknown] are present. [Bug
+	1439836]
+
+2006-02-22  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Corrected a few bugs in how [namespace

+	[Patch 958222]
+
+2006-02-17  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIORChan.c: Revised error message generation and handling

+	reflection layer. [Bug 1372348]
+
+2006-02-16  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIndexObj.c:	Disallow the "ambiguous" error message
+	* tests/indexObj.test:		when TCL_EXACT matching is requested.
+	* tests/ioCmd.test:
+
+2006-02-15  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIO.c:	Made several routines tolerant of
+	* generic/tclIORChan.c: interp == NULL arguments. [Bug 1380662]
+	* generic/tclIOUtil.c:
+
+2006-02-09  Don Porter	<dgp@users.sourceforge.net>
+
+	TIP#215 IMPLEMENTATION
+
+	* doc/incr.n:		Revised [incr] to auto-initialize when varName
+	* generic/tclExecute.c: argument is unset. [Patch 1413115]
+	* generic/tclVar.c:
+	* tests/compile.test:
+	* tests/incr-old.test:
+	* tests/incr.test:
+	* tests/set.test:
+
+	* tests/main.test (Tcl_Main-6.7):	Improved robustness of

+
+2006-02-08  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/Encoding.3, doc/encoding.n: Updates due to review at request of
+	Don Porter. Mostly minor changes.
+
+2006-02-08  Don Porter	<dgp@users.sourceforge.net>
+
+	TIP#258 IMPLEMENTATION
+
+	* doc/Encoding.3:	New subcommand [encoding dirs].
+	* doc/encoding.n:	New routine Tcl_GetEncodingNameFromEnvironment
+	* generic/tcl.decls:	Made public:

+	* tests/upvar.test:
+
+2006-01-26  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/dict.n: Fixed silly bug in example. Thanks to Heiner Marxen
+	<heiner.marxen@unsel.de> for catching this! [Bug 1415725]
+
+2006-01-26  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* unix/tclUnixChan.c (TclpOpenFileChannel): Tidy up and comment the
+	mess to do with setting up serial channels. This (deliberately) breaks
+	a broken FreeBSD port, indicates what we're really doing, and reduces
+	the amount of conditional compilation sections for better maintenance.
+
+2006-01-25  Donal K. Fellows  <dkf@users.sf.net>
+
+	* unix/tclUnixInit.c (TclpInitPlatform): Improved conditions on when
+	to update the FP rounding mode on FreeBSD, taken from FreeBSD port.
+
+2006-01-23  Donal K. Fellows  <dkf@users.sf.net>
+
+	* tests/string.test (string-12.21): Added test for [Bug 1410553] based
+	on original bug report.
+
+2006-01-23  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclStringObj.c: fixed incorrect handling of internal rep in
+	Tcl_GetRange. Thanks to twylite and Peter Spjuth. [Bug 1410553]
+
+	* generic/tclProc.c: fixed args handling for precompiled bodies [Bug
+	1412695]; thanks to Uwe Traum.
+
+2006-01-16  Reinhard Max  <max@suse.de>
+
+	* generic/tclPipe.c (FileForRedirect): Prevent nameString from being
+	freed without having been initialized.
+	* tests/exec.test: Added a test for the above.
+
+2006-01-12  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>
+
+	* generic/tclPathObj.c (Tcl_FSGetInternalRep): backported patch from
+	core-8-4-branch. A freed pointer has been overwritten causing all
+	sorts of coredumps.
+
+2006-01-12  Vince Darley  <vincentdarley@sourceforge.net>
+
+	* win/tclWinFile.c: fix to sharing violation [Bug 1366227]
+
+2006-01-11  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Moved Tcl_LogCommandInfo from tclBasic.c to
+	* generic/tclNamesp.c:	tclNamesp.c to get access to identifier with
+	* tests/error.test (error-7.0): file scope. Added check for traces on
+	::errorInfo, and when present fall back to contruction of the stack
+	trace in the variable so that write trace notification timings are
+	compatible with earlier Tcl releases. This reduces, but does not
+	completely eliminate the ***POTENTIAL INCOMPATIBILITY*** created by
+	the 2004-10-15 commit. [Bug 1397843]
+
+2006-01-10  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/configure:    add caching, use AC_CACHE_CHECK instead of
+	* unix/configure.in: AC_CACHE_VAL where possible, consistent message
+	* unix/tcl.m4:	     quoting, sync relevant tclconfig/tcl.m4 changes
+	and gratuitous formatting differences, fix SC_CONFIG_MANPAGES with
+	default argument, Darwin improvements to SC_LOAD_*CONFIG.
+
+2006-01-09  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclNamesp.c (NamespaceInscopeCmd):	[namespace inscope]
+	* tests/namespace.test: commands were not reported by [info level].
+	[Bug 1400572]
+
+2006-01-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclTrace.c: Stop exporting the guts of the trace command;
+	nothing outside this file needs to see it. [Bug 971336]
+
+2006-01-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* unix/tcl.m4 (TCL_CONFIG_SYSTEM): Factor out the code to determine
+	the operating system version number, as it was replicated in several
+	places.
+
+2006-01-04  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/tclAppInit.c: WIN32 native console signal handler removed. This
+	was found to be interfering with TWAPI extension one. IMO, special
+	services such as signal handlers should best be done with extensions
+	to the core after discussions on c.l.t. about Roy Terry's tclsh
+	children of a real windows service shell.

+2008-12-31  Don Porter  <dgp@users.sourceforge.net>
+
+	* unix/Makefile.in:	Set TCLLIBPATH in SHELL_ENV so that targets

+	* generic/tcl.decls:		     2470237]
+
+	* generic/tclZlib.c (Tcl_ZlibStreamGet): Corrected the semantics of
+	this function to be useful to the PNG implementation. If the argument
+	object is empty, this gives the previous semantics.
+	(Tcl_ZlibStreamChecksum): Corrected name to be less misleading; it
+	only produced Adler-32 checksums when the stream was processing the
+	right type of compressed data format.
+	(Tcl_ZlibAdler32, Tcl_ZlibCRC32): Corrected types so that they work
+	naturally with the results of Tcl_GetByteArrayFromObj().

+	unlikely to be difficult for anyone to deal with.
+
+2008-12-26  Donal K. Fellows  <dkf@users.sf.net>
+

+	each of the big release points under TCT stewardship and noting the
+	general purpose of each TIP that added C API. Overall effect is to
+	make this file much more informative to read without having to spend
+	effort correlating with TIPs and ChangeLogs.
+
+2008-12-23  Jan Nijtmans  <nijtmans@users.sf.net>

+				to build dir contains spaces by switching to
+				relative paths to toplevel build dir.
+

+				sub-configures of bundled packages; reuse

+
+	* win/Makefile.in:	Renamed the static library libtcl86s.a to
+	* win/configure.in:	have a name distinct from the import library
+				libtcl86.a. This renaming dodges an ancient
+				bug in the Makefile revealed by the last
+				commit where the $(TCL_LIB_FILE) rule can
+				fire to try to build the static library in a
+				--enable-shared build (and create a static
+				library that subsequently fails to link).
+				Revised the zlib objects so that they are
+				built directly into the build dir, without
+				building an intermediate static library.
+				*** POTENTIAL INCOMPATIBILITY *** for
+				embedders who link to the static library, but
+				I couldn't figure out how to sort this out
+				any other way.
+	* win/configure:	Autoconf 2.59
+
+2008-12-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* win/Makefile.in: Minor updates to make building work better with
+	msys on Windows. (Apparently the gcc used doesn't like a / at the end
+	of a -I argument...)
+
+2008-12-20  Don Porter  <dgp@users.sourceforge.net>
+
+	* changes:	Updates for 8.6b1 release.
+
+2008-12-20  Daniel Steffen  <das@users.sourceforge.net>
+

+	* unix/configure.in:	packages configurable via PACKAGE_DIR makefile
+				variable (set to platform-specific default).
+
+	* unix/Makefile.in (*-packages): Ensure toplevel targets fail if
+				sub-make/configure fails; fix quoting when

+	(ChanCloseHalf): Rewrite the half-close to properly flush the channel,
+	like is done for a full close, going through FlushChannel, and using
+	the flag BG_FLUSH_SCHEDULED (async flush during close). New functions
+	CloseWrite, CloseChannelPart, new flag CHANNEL_CLOSEDWRITE.
+
+	* tests/chanio.test (chanio-28.[67]): Reactivated these tests.

+	classes are resolved from the perspective of the caller of the
+	[oo::define] command, rather than from the oo::define namespace! This
+	makes much code simpler by reducing how often fully-qualified names
+	are required (previously always in practice, so no back-compat issues
+	exist). [Bug 2200824]

+	code compatibility with Tcl 8.5 on those public routines passing
+	(Tcl_Filesystem *), (Tcl_Timer *), and (Tcl_Objtype *) values which

+2008-08-11  Andreas Kupries  <andreask@activestate.com>
+
+	* library/tm.tcl: Added a 'package provide' command to the generated

+2008-08-03  Miguel Sofer  <msofer@users.sf.net>
+

+2008-08-01  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Revised timing of the CmdFrame stack
+	* tests/info.test:	management in TclEvalEx so that the CmdFrame
+	will still be on the stack at the time Tcl_LogCommandInfo is called to
+	append another level of -errorinfo information. Sets the stage to add

+2008-07-31  Miguel Sofer  <msofer@users.sf.net>
+
+	* tests/NRE.test:  Replaced all deep-recursing tests by shallower
+	tests that actually measure the C-stack depth. This makes them

+	* generic/tclExecute.c:
+
+	* generic/tclBasic.c:	Made use of the thread's alloc cache stored in

+	* generic/tclNRE.h:	the TSD each time an NRE callback is pushed or
+	* generic/tclThreadAlloc.c: pulled; the approach is suitably general
+	to extend to every other obj allocation where an interp is know; this

+	to panic on rare corner cases. Thx ajpasadyn for diagnose and patch.
+
+	* generic/tcl.decls:	 Completely revamped NRE implementation, with
+	* generic/tclBasic.c:	 (almost) unchanged API.
+	* generic/tclCompile.h:
+	* generic/tclExecute.c:	 TEBC will require a bit of a facelift, but
+	* generic/tclInt.decls:	 TEOV at least looks great now. There are new

+	* generic/tclOOBasic.c:	 in tcl::unsupported.
+	* generic/tclOOMethod.c:
+	* generic/tclProc.c:	 Uninit'd var warnings in TEBC with -O2, no

+
+	* doc/FileSystem.3:		CONSTified many functions using

+
+2008-07-28  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclBasic.c: Added missing ref count when creating an empty
+	string as path (TclEvalEx). In 8.4 the missing code caused panics in
+	the testsuite. It doesn't in 8.5. I am guessing that the code path
+	with the missing the incr-refcount is not invoked any longer. Because
+	the bug in itself is certainly the same.
+
+2008-07-27  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclOOMethod.c (PushMethodCallFrame): Remove hack that should

+
+	* doc/Object.3:		CONSTified 3 functions using Tcl_ObjType

+	* generic/tcl.h:	Tcl_RegisterObjType, Tcl_ConvertToType,
+	* generic/tclDecls.h:	Tcl_GetObjType
+	* generic/tclObj.c:	Introduced a CONST86_RETURN, so extensions

+	* generic/tclOOMethod.c: modified to compile against both Tcl 8.5 and
+	* generic/tclTestobj.c:	Tcl 8.6. tclDecls.h regenerated

+
+	* test/info.test: More work on singleTestInterp usability. [1605269]
+
+	* tests/info.test: Tests 38.* added, exactly testing the tracking of
+	location for uplevel scripts. Resolved merge conflict on info-37.0,
+	switched !singleTestInterp constraint to glob matching instead. Ditto
+	info-22.8, removed constraint, more glob matching, and reduced the
+	depth of the stack we check. More is coming, right now I want to
+	commit the bug fixes.
+
+	* tests/oo.test: Updated oo-22.1 for expanded location tracking.
+
+	* generic/tclCompile.c (TclInitCompileEnv): Reorganized the
+	initialization of the #280 location information to match the flow in
+	TclEvalObjEx to get more absolute contexts.
+

+	location information.
+
+2008-07-25  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tests/info.test (info-37.0): Add !singleTestInterp constraint;

+	expected result. [Bug 1605269]
+
+2008-07-24  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* doc/Notifier.3:      CONSTified 4 functions in the Notifier which
+	* doc/Thread.3:	       all have a Tcl_Time* in it which is supposed
+	* generic/tcl.decls:   to be a constant, but this was not reflected

+	* generic/tclNotify.c:	    Tcl_ConditionWait, Tcl_SetMaxBlockTime
+	* macosx/tclMacOSXNotify.c:

+	* win/tclWinNotify.c:  Tcl 8.5 and Tcl 8.6
+	* win/tclWinThrd.c:    Regenerated tclDecls.h with "make stubs".

+
+2008-07-23  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/info.test: Reordered the tests to have monotonously increasing
+	numbers.
+
+	* generic/tclBasic.c: Modified TclArgumentGet to reject pure lists
+	* generic/tclCmdIL.c: immediately, without search. Reworked setup of
+	* generic/tclCompile.c: eoFramePtr, doesn't need the line information,
+	* tests/info.test: more sensible to have everything on line 1 when
+	eval'ing a pure list. Updated the users of the line information to
+	special case this based on the frame type (i.e.
+	TCL_LOCATION_EVAL_LIST). Added a testcase demonstrating the new
+	behaviour.

+2008-07-23  Miguel Sofer  <msofer@users.sf.net>
+

+
+2008-07-22  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclCompile.c: Made the new TclEnterCmdWordIndex static, and
+	* generic/tclCompile.h: ansified.
+
+	* generic/tclBasic.c: Ansified the new functions. Added missing
+	function comments.
+
+	* generic/tclBasic.c: Reworked the handling of bytecode literals for
+	* generic/tclCompile.c: #280 to fix the abysmal performance for deep
+	* generic/tclCompile.h: recursion, replaced the linear search through
+	* generic/tclExecute.c: the whole stack with another hashtable and
+	* generic/tclInt.h: simplified the data structure used by the compiler
+	by using an array instead of a hashtable. Incidentially this also
+	fixes the memory leak reported via [Bug 2024937].
+
+2008-07-22  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c:	 Added numLevels field to CommandFrame, let

+
+2008-07-21  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclBasic.c: Extended the existing TIP #280 system (info
+	* generic/tclCmdAH.c: frame), added the ability to track the absolute
+	* generic/tclCompCmds.c: location of literal procedure arguments, and
+	* generic/tclCompile.c: making this information available to uplevel
+	* generic/tclCompile.h: eval, and siblings. This allows proper

+2008-07-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c (SetDictFromAny): Make the list->dict
+	transformation a bit more efficient; modern dicts are ordered and so
+	we can round-trip through lists without needing the string rep at all.
+	* generic/tclListObj.c (SetListFromAny): Make the dict->list
+	transformation not lossy of internal representations and hence more
+	efficient. [Bug 2008248] (ajpasadyn) but using a more efficient patch.
+
+	* tests/fileName.test: Revise to reduce the obscurity of tests. In
+	particular, all tests should now produce informative messages on
+	failure and the quantity of [catch]-based obscurity is now greatly
+	reduced; non-erroring is now checked for directly.
+
+2008-07-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* tests/env.test: Add LANG to the list of variables that are not
+	touched by the environment variable tests, so that subprocesses can
+	get their system encoding correct.
+
+	* tests/exec.test, tests/env.test: Rewrite so that non-ASCII
+	characters are not used in the final comparison. Part of fixing [Bug

+
+2008-07-03  Don Porter  <dgp@users.sourceforge.net>
+
+	* library/package.tcl:	Removed [file readable] testing from

+
+	* generic/regc_nfa.c (duptraverse): Impose a maximum stack depth on

+
+2008-06-23  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclPathObj.c: Fixed bug in Tcl_GetTranslatedPath() when
+	operating on the "Special path" variant of the "path" Tcl_ObjType
+	intrep. A full normalization was getting done, in particular, coercing
+	relative paths to absolute, contrary to what the function of producing

+	compilation. [Bug 1987851]
+
+2008-06-16  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/ioTrans.test (iortrans-11.*): Fixed same issue as for

+
+2008-06-13  David Gravereaux  <davygrvy@pobox.com>
+

+
+2008-06-13  Joe Mistachkin  <joe@mistachkin.com>
+
+	TIP #285 IMPLEMENTATION
+
+	* doc/Eval.3: Added documentation for the Tcl_CancelEval and
+	Tcl_Canceled functions and the TCL_CANCEL_UNWIND flag bit.
+	* doc/after.n: Corrected the spelling of 'canceled' in the
+	documentation.
+	* doc/interp.n: Added documentation for [interp cancel].
+	* generic/tcl.decls: Added the Tcl_CancelEval and Tcl_Canceled
+	functions to the stubs table.
+	* generic/tcl.h: Added the TCL_CANCEL_UNWIND flag bit.
+	* generic/tclBasic.c: The bulk of the script cancellation
+	functionality is defined here. Added code to initialize and manage the
+	script cancellation hash table in a thread-safe manner. Reset script
+	cancellation flags prior to increasing the nesting level (if the
+	nesting level is currently zero) and always cooperatively check for
+	script cancellation near the start of TclEvalObjvInternal and after
+	invoking async handlers.
+	* generic/tclDecls.h: Regenerated.
+	* generic/tclEvent.c: Call TclFinalizeEvaluation during finalization
+	to cleanup the script cancellation hash table. During [vwait], always
+	cooperatively check for script cancellation. Corrected the spelling of
+	'canceled' in comments to be consistent with the documentation.
+	* generic/tclExecute.c: Reset script cancellation flags prior to
+	increasing the nesting level (if the nesting level is currently zero)
+	and always cooperatively check for script cancellation after invoking
+	async handlers. Prevent [catch] from catching script cancellation when
+	the TCL_CANCEL_UNWIND flag is set (similar to the manner used by TIP
+	143 when a limit has been exceeded).
+	* generic/tclInt.decls: Added TclResetCancellation to the internal
+	stubs table.
+	* generic/tclInt.h: Added asyncCancel and asyncCancelMsg fields to the
+	private Interp structure. Added private interp flag value CANCELED to
+	help control script cancellation.
+	* generic/tclIntDecls.h: Regenerated.
+	* generic/tclInterp.c (Tcl_InterpObjCmd): Added [interp cancel]
+	subcommand.
+	* generic/tclNotify.c (Tcl_DeleteEventSource): Corrected the spelling
+	of 'canceled' in comments to be consistent with the documentation.
+	* generic/tclParse.c: Reset script cancellation flags prior to
+	* generic/tclProc.c: increasing the nesting level (if the nesting
+	level is currently zero) and cooperatively check for script
+	cancellation prior to evaluating commands.
+	* generic/tclStubInit.c: Regenerated.
+	* generic/tclThreadTest.c (Tcl_ThreadObjCmd): Added script
+	cancellation support ([testthread cancel]).
+	Modified [testthread id] to allow querying of the 'main' thread ID.
+	Corrected comments to reflect the actual command syntax. Made
+	[testthread wait] cooperatively check for script cancellation. Added
+	[testthread event] to allow for processing one pending event without
+	blocking.
+	* generic/tclTimer.c: Delay for a maximum of 500 milliseconds prior to
+	checking for async handlers and script cancellation.
+	* tests/cmdAH.test: Changed [interp c] to [interp create].
+	* tests/interp.test: Added and fixed tests for [interp cancel].
+	* tests/thread.test: Added tests for script cancellation via
+	[testthread cancel].
+	* tools/man2help2.tcl: Fixed problems with WinHelp target (see
+	* tools/man2tcl.c: [Bug 1934200], [Bug 1934265], and [Bug 1934272]).
+	* win/makefile.vc: Added 'pdbs' option for Windows build rules to
+	* win/rules.vc:	   allow for non-debug builds with full symbols.
+	* win/tcl.hpj.in: Corrected version for WinHelp target.
+	* win/tclWinNotify.c: Used SleepEx and WaitForSingleObjectEx on
+	* win/tclWinThrd.c: Windows because they are alertable.
+
+2008-06-12  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/Makefile.in:		Add complete deps on tclDTrace.h.

+	* unix/configure.in (SunOS):	Fix static DTrace-enabled build.
+
+	* unix/tcl.m4 (SunOS-5.11): Fix 64bit amd64 support with gcc & Sun cc.
+	* unix/configure: autoconf-2.59
+
+	* macosx/Tcl.xcodeproj/project.pbxproj:	Add tclIORTrans.c; updates and
+						cleanup for Xcode 3.1/Leopard.
+	* macosx/Tcl.xcode/project.pbxproj:	Sync Tcl.xcodeproj changes.
+	* macosx/README:			Document new build configs.
+
+2008-06-10  Joe English  <jenglish@users.sourceforge.net>
+
+	* generic/tclEncoding.c(UtfToUtfProc): Avoid unwanted sign extension
+	when converting incomplete UTF-8 sequences. See [Bug 1908443] for
+	details.
+
+2008-06-10  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/ioTrans.test (iortrans.tf-6.1): Fixed the [Bug 1988552],
+	reported by Kevin. Have to close the channel before removal of the
+	file. Fixed same bug in test 'iortrans.tf-11.0', after fixing missing
+	cleanup of the file in 'iortrans.tf-11.*'. Lastly fixed the names of
+	the threaded tests 'iortrans-8.*' to the correct 'iortrans.tf-8.*'.
+
+2008-06-09  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* generic/tclIORTrans.c (ReflectInput): Fixed a bug triggered by Pat
+	Thoyts <patthoyts@users.sourceforge.net>. Reset the EOF flag after
+	draining the Tcl level into the result buffer, to make sure that the
+	result buffer will be drained as well by repeated calls to
+	ReflectInput should it contain more than one buffer-full of data.
+	Without that reset the higher I/O system will not call on ReflectInput
+	anymore due to the assumed EOF, thus losing the data which did not fit
+	in the buffer of the call which caused the eof and drain.
+
+2008-06-09  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclOOCall.c (TclOOGetSortedMethodList): Plug memory leak
+	that occurred when all methods were hidden. [Bug 1987817]
+
+2008-06-08  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c:	   Compilation of uplevel scripts, allow

+	* win/makefile.vc:  Integration of new files into build rules.
+
+	NOTE: The file 'tclIORTrans.c' has a lot of code in common with the
+	      file 'tclIORChan.c', as that made it much easier to develop the
+	      reference implementation as a separate module. Now that the

+
+2008-06-01  Donal K. Fellows  <dkf@users.sf.net>
+

+
+2008-06-01  Joe Mistachkin  <joe@mistachkin.com>
+
+	* win/Makefile.in: Add tclOO genstubs to Windows makefiles and remove

+
+2008-06-01  Kevin B. Kenny  <kennykb@acm.org>
+

+
+	* generic/tclDictObj.c:	 Added missing initializers to the ensemble
+				 map to silence a compiler warning. Thanks to
+				 George Peter Staplin for the report.
+
+	* generic/tclOOMethod.c: Fix a bug where the refcount of a method was

+	* generic/tclCompile.c: Fix crash with tcl_traceExec. Found and fixed
+	by Alexander Pasadyn. [Bug 1964803]
+
+2008-05-15  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* win/makefile.vc: We should use the thread allocator for threaded

+
+2008-05-09  George Peter Staplin  <georgeps@xmission.com>
+
+	* tools/tsdPerf.c:	A loadable Tcl extension for testing TSD
+	performance.
+	* tools/tsdPerf.tcl:	A simplistic tool that uses the thread
+	extension and tsdPerf.so to get some performance metrics by,
+	simulating, simple TSD contention.
+
+2008-05-09  George Peter Staplin  <georgeps@xmission.com>
+
+	* generic/tcl.h:	Make Tcl_ThreadDataKey a void *.
+	* generic/tclInt.h:	Change around some function names and add some
+	new per-platform declarations for thread-specific data functions.
+	* generic/tclThread.c:	Make use of of the new function names that no
+	longer have a Tclp prefix.
+	* generic/tclThreadStorage.c: Replace the core thread-specific data
+	(TSD) mechanism with an array offset solution that eliminates the hash
+	tables, and only uses one slot of native TSD. Many thanks to Kevin B.
+	Kenny for his help with this.
+
+	* unix/tclUnixThrd.c:	Add platform-specific TSD functions for use by
+	* win/tclWinThrd.c:	tclThreadStorage.c.
+
+2008-05-09  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tests/dict.test (dict-19.2): Corrected a bug where the test was
+	changed to use [apply] instead of a temporary proc, but the cleanup
+	script still attempted to delete the temporary proc.
+
+2008-05-07  Donal K. Fellows  <dkf@cspool38.cs.man.ac.uk>
+
+	* generic/tclCompCmds.c (TclCompileDictAppendCmd): Fix silly off-by
+	one error that caused a crash every time a compiled 'dict append' with
+	more than one argument was used. Found by Colin McCormack.
+
+2008-05-02  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* generic/tclBasic.c:	 Converted the [binary] command into an
+	* generic/tclBinary.c:	 ensemble.
+	* generic/tclInt.h:
+	* test/binary.test:	 Updated the error tests for ensemble errors.
+
+	* generic/tclFileName.c: Reverted accidental commit of TIP 316 APIs.
+
+2008-04-27  Donal K. Fellows  <dkf@users.sf.net>
+
+	* */*.c: A large tranche of getting rid of pre-C89-isms; if your
+	compiler doesn't support things like proper function declarations,
+	'void' and 'const', borrow a proper one when building Tcl. (The header
+	files allow building things that link against Tcl with really ancient
+	compilers still; the requirement is just when building Tcl itself.)
+
+2008-04-26  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>
+
+	* generic/tclAsync.c: Tcl_AsyncDelete(): panic if attempt to locate
+	handler token fails. Happens when some other thread attempts to delete
+	somebody else's token.
+
+	Also, panic early if we find out the wrong thread attempting to delete
+	the async handler (common trap). As, only the one that created the
+	handler is allowed to delete it.
+
+2008-04-24  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/ioCmd.test: Extended testsuite for reflected channel
+	implementation. Added test cases about how it handles if the rug is
+	pulled out from under a channel (= killing threads, interpreters
+	containing the tcl command for a channel, and channel sitting in a
+	different interpreter/thread.)
+
+	* generic/tclIORChan.c: Fixed the bugs exposed by the new testcases,
+	redone most of the cleanup and exit handling.
+
+2008-04-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclIOUtil.c:		Removed all code delimited by
+	* generic/tclTest.c:		USE_OBSOLETE_FS_HOOKS, completing
+	* tests/ioCmd.test:		the deprecation path for these
+	* tests/ioUtil.test (removed):	obsolete interfaces. (Code was active
+	in Tcl 8.4, present but enabled only by customized compile switch in
+	Tcl 8.5, and now completely gone for Tcl 8.6). Also removed all tests
+	relevant only to the removed interfaces.
+
+2008-04-19  George Peter Staplin  <georgeps@xmission.com>
+
+	* doc/Ensemble.3: Fix a typo: s/defiend/defined/
+	Thanks to hat0 for spotting this.
+
+2008-04-16  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclInt.h:		Make stubs tables 'static const' and
+	* generic/tclStubInit.c:	export only module-scope pointers to
+	* generic/tclStubLib.c:		the main stubs tables (for package
+	* tools/genStubs.tcl:		initialization). [Patch 1938497]
+	* generic/tclBasic.c (Tcl_CreateInterp):
+	* generic/tclTomMathInterface.c (TclTommath_Init):
+
+	* generic/tclInt.h:		Revise Tcl_SetNotifier() to use a
+	* generic/tclNotify.c:		module-scope hooks table instead of
+	* generic/tclStubInit.c:	runtime stubs-table modification;
+	* macosx/tclMacOSXNotify.c:	ensure all hookable notifier functions
+	* win/tclWinNotify.c:		check for hooks; remove hook checks in

+
+2008-04-15  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (CopyData):	Applied another patch by Alexandre
+	* io.test (io-53.8a):		Ferrieux <ferrieux@users.sf.net>,
+	* chanio.test (chan-io-53.8a):	to shift EOF handling to the async
+	part of the command if a callback is specified, should the channel be
+	at EOF already when fcopy is called. Testcase by myself.
+
+2008-04-15  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/Makefile.in:	Adjust tclDTrace.h dependencies for removal
+				of tclStubLib.o from TCL_OBJS. [Bug 1942795]
+
+2008-04-14  Kevin B. Kenny  <kennykb@acm.org>
+
+	* unix/tclUnixTime.c (NativeGetTime): Removed obsolete use of
+	'struct timezone' in the call to 'gettimeofday'. [Bug 1942197]
+
+	* tests/clock.test (clock-33.5, clock-33.5a, clock-33.8, clock-33.8a):
+	Added comments to the test that it can fail on a heavily loaded
+	system.
+
+2008-04-10  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Keeping check for negative
+	values, changed to not be an error, but behave like the special value
+	-1 (copy all, default).
+
+	* tests/iocmd.test (iocmd-15.{12,13}): Removed.
+
+	* tests/io.test (io-52.5{,a,b}): Reverted last change, added
+	* tests/chanio.test (chan-io-52.5{,a,b}): comment regarding the
+	meaning of -1, added two more testcases for other negative values,
+	and input wrapped to negative.
+
+2008-04-09  Donal K. Fellows  <dkf@users.sf.net>
+
+	* tests/{fCmd,unixFCmd,winFCmd,winFile}.test: Tidying up of the test
+	suite to make better use of tcltest2 and be clearer about what is
+	being tested.
+
+	* win/Makefile.in (html): Added target for doing convenient
+	documentation builds, mirroring the one from unix/Makefile.
+
+2008-04-09  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/chanio.test (chan-io-52.5): Removed '-size -1' from test,
+	* tests/io.test (io-52.5): does not seem to have any bearing, and was
+	an illegal value. Test case is not affected by the value of -size,
+	test flag restoration and that evrything was properly copied.
+
+	* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Added checking of -size value
+	* tests/ioCmd.test (iocmd-15.{13,14}): to reject negative values, and
+	values overflowing 32-bit signed. Basic patch by Alexandre Ferrieux
+	<ferrieux@users.sourceforge.net>, with modifications from me to
+	separate overflow from true negative value. Extended testsuite. [Bug
+	1557855]
+
+2008-04-09  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tests/chanio.test (chan-io-53.8,53.9,53.10): Fix typo & quoting for
+	* tests/io.test (io-53.8,53.9,53.10):	       spaces in builddir path
+
+2008-04-08  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: Added comments to the alignment macros used in
+	GrowEvaluationStack() and friends.
+
+2008-04-08  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tools/genStubs.tcl:	Revert erroneous 2008-04-02 change marking
+				*StubsPtr as EXTERN instead of extern.

+	* generic/tclDecls.h:	make genstubs
+	* generic/tclIntDecls.h:
+	* generic/tclIntPlatDecls.h:

+2008-04-07  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/io.test (io-53.10): Testcase for bi-directional fcopy.
+	* tests/chanio.test:
+	* generic/tclIO.c: Additional changes to data structures for fcopy and
+	* generic/tclIO.h: channels to perform proper cleanup in case of a
+	channel having two background copy operations running as is now
+	possible.
+
+	* generic/tclIO.c (BUSY_STATE, CheckChannelErrors, TclCopyChannel):
+	New macro, and the places using it. This change allows for
+	bi-directional fcopy on channels. Thanks to Alexandre Ferrieux
+	<ferrieux@users.sourceforge.net> for the patch. [Bug 1350564]
+
+2008-04-07  Reinhard Max  <max@suse.de>
+
+	* generic/tclStringObj.c (Tcl_AppendFormatToObj): Fix [format {% d}]
+	so that it behaves the same way as in 8.4 and as C's printf().
+	* tests/format.test: Add a test for '% d' and '%+d'.
+
+2008-04-05  Kevin B. Kenny  <kennykb@acm.org>
+
+	* win/tclWinFile.c: (WinSymLinkDirectory): Fixed a problem that Tcl
+	was creating an NTFS junction point (IO_REPARSE_TAG_MOUNT_POINT) but
+	filling in the union member for a Vista symbolic link. We had gotten
+	away with this error because the union member
+	(SymbolicLinkReparseBuffer) was misdefined in this file and in the
+	'winnt.h' in early versions of MinGW. MinGW 3.4.2 has the correct
+	definition of SymbolicLinkReparseBuffer, exposing the mismatch, and
+	making tests cmdAH-19.4.1, fCmd-28.*, and filename-11.* fail.
+	* tests/chanio.test (chan-io-53.9):
+	* tests/io.test (io-53.9): Made test cleanup robust against the
+	possibility of slow process shutdown on Windows.
+
+	* win/tcl.m4: Added -D_CRT_SECURE_NO_DEPRECATE and
+	-DCRT_NONSTDC_NO_DEPRECATE to the MSVC compilation flags so that the
+	compilation doesn't barf on perfectly reasonable Posix system calls.
+	* win/configure: Manually patched (don't have the right autoconf to
+	hand).
+
+2008-04-04  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/io.test (io-53.9): Added testcase for [Bug 780533], based
+	* tests/chanio.test: on Alexandre's test script. Also fixed problem
+	with timer in preceding test, was not canceled properly in the ok case
+
+2008-04-04  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIORChan.c (ReflectOutput): Allow zero return from write
+	when input was zero-length anyway. Otherwise keept it an error, and
+	separate the message from 'written too much'.
+
+	* tests/ioCmd.test (iocmd-24.6): Testcase updated for changed message.
+
+	* generic/tclIORChan.c (ReflectClose): Added missing removal of the
+	now closed channel from the reflection map. Before we could crash the
+	system by invoking 'chan postevent' on a closed reflected channel,
+	dereferencing the dangling pointer in the map.
+
+	* tests/ioCmd.test (iocmd-31.8): Testcase for the above.
+
+2008-04-03  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (CopyData): Applied patch [Bug 1932639] to
+	* tests/io.test: prevent fcopy from calling -command synchronously
+	* tests/chanio.test: the first time. Thanks to Alexandre Ferrieux
+	<ferrieux@users.sourceforge.net> for report and patch.
+
+2008-04-02  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tcl.decls:	Remove 'export' declarations of symbols now
+				only in libtclstub and no longer in libtcl.
+
+	* generic/tclStubLib.c:	Make symbols in libtclstub.a MODULE_SCOPE to
+	* tools/genStubs.tcl:	avoid exporting them from libraries that link
+				with -ltclstub; constify tcl*StubsPtr and stub
+				table hook pointers. [Bug 1819422]

+	case.
+
+2008-04-01  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclStrToD.c: Applied patch for [Bug 1839067] (fp rounding

+			       Michael Schlenker.
+
+2008-04-01  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStubLib.c:	Removed needless #ifdef complexity.

+
+2008-03-30  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclInt.h (TclIsNaN):
+	* unix/configure.in: Added code to the configurator to check for a
+			     standard isnan() macro and use it if one is
+			     found. This change avoids bugs where the test of
+			     ((d) != (d)) is optimized away by an
+			     overaggressive compiler. [Bug 1783544]
+	* generic/tclObj.c: Added missing #include <math.h> needed to locate
+			    isnan() after the above change.
+
+	* unix/configure: autoconf-2.61
+
+	* tests/mathop.test (mathop-25.9, mathop-25.14): Modified tests to
+	deal with (slightly buggy) math libraries in which pow() returns an
+	incorrectly rounded result. [Bug 1808174]
+
+2008-03-26  Don Porter  <dgp@users.sourceforge.net>

+
+2008-03-28  Donal K. Fellows  <dkf@users.sf.net>
+

+2008-03-24  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* generic/tclBinary.c: [Bug 1923966] - crash in binary format

+
+2008-03-21  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/switch.n: Clarified documentation in respect of two-argument
+	invokation. [Bug 1899962]

+
+2008-03-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tcl.h, generic/tclThreadAlloc.c: Tidied up the declarations
+	of Tcl_GetMemoryInfo so that it is always defined. Will panic when
+	called against a Tcl that was previously built without it at all,
+	which is OK because that also indicates a serious mismatch between
+	memory configuration options.
+
+2008-03-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tcl.h, generic/tclThreadAlloc.c (Tcl_GetMemoryInfo): Make
+	sure this function is available when direct linking. [Bug 1868171]
+
+	* tests/reg.test (reg-33.14): Marked nonPortable because some
+	environments have small default stack sizes. [Bug 1905562]
+
+2008-03-18  Andreas Kupries  <andreask@activestate.com>
+
+	* library/tm.tcl (::tcl::tm::UnknownHandler): Changed 'source' to
+	'source -encoding utf-8'. This fixes a portability problem of Tcl
+	Modules pointed out by Don Porter. By using plain 'source' we were at
+	the mercy of 'encoding system', making modules less portable than they
+	could be. The exact scenario: A writes a TM in some weird encoding
+	which is A's system encoding, distributes it, and somewhere else it
+	cannot be read/used because the system encoding is different. Forcing
+	the use of utf-8 makes the module portable.
+
+	***INCOMPATIBILITY*** for all Tcl Modules already written in non-utf-8
+	compatible encodings.

+2008-03-18  Don Porter  <dgp@users.sourceforge.net>

+
+2008-03-18  Andreas Kupries  <andreask@activestate.com>
+
+	* library/tm.tcl (::tcl::tm::Defaults): Modified handling of
+	environment variables. Solution slightly different than proposed in
+	the report. Using the underscored form TCLX_y_TM_PATH even if
+	TCLX.y_TM_PATH exists. Also using a loop to cut prevent code
+	replication. [Bug 1914604]
+
+2008-03-16  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileDictForCmd): Correct the handling
+	of stack space calculation (the jump pattern used was confusing the
+	simple-minded code doing the calculations). [Bug 1903325]
+
+	* doc/lreplace.n: Clarified documentation of what happens with
+	negative indices. [Bug 1905809] Added example, tidied up formatting.
+
+2008-03-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (OldMathFuncProc):	Same workaround protection
+	from bad TclStackAlloc() alignment. Thanks George Peter Staplin.
+
+	* generic/tclCmdIL.c (Tcl_LsortObjCmd):	Use ckalloc() to allocate
+	SortElement arrays instead of TclStackAlloc() which isn't getting

+	* doc/http.n:				[Bug 1599901, 862554]
+

+
+2008-03-11  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclEncoding.c (LoadEscapeEncoding): Avoid leaking escape
+	sub-encodings, fixes encoding-11.1 failing after iso2022-jp loaded.
+	[Bug 1893053]
+
+	* macosx/tclMacOSXNotify.c: Avoid using CoreFoundation after fork() on
+	Darwin 9 even when TclpCreateProcess() uses vfork().
+
+	* macosx/Tcl.xcodeproj/project.pbxproj:	Add support for Xcode 3.1 and
+	* macosx/Tcl.xcodeproj/default.pbxuser:	configs for building with
+	* macosx/Tcl-Common.xcconfig:		gcc-4.2 and llvm-gcc-4.2.
+
+	* unix/tclUnixPort.h:			Workaround vfork() problems in
+						llvm-gcc-4.2.1 -O4 build.
+
+	* unix/tclUnixPort.h:			Move MODULE_SCOPE compat
+						define to top. [Bug 1911102]
+
+	* macosx/GNUmakefile:			Fix quoting to allow paths
+	* macosx/Tcl-Common.xcconfig:		to ${builddir} and
+	* unix/Makefile.in:			${INSTALL_ROOT} to contain
+	* unix/configure.in:			spaces.
+	* unix/install-sh:

+	* tests/ioCmd.test:
+
+	* unix/configure:			autoconf-2.59

+
+2008-03-11  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclVar.c (TclDeleteNamespaceVars):
+	* tests/var.test (var-8.2): Unset traces on vars should be called with
+	a FQ named during namespace deletion. This was causing infinite loops
+	when unset traces recreated the var, as reported by Julian Noble. [Bug
+	1911919]
+
+2008-03-10  Don Porter  <dgp@users.sourceforge.net>
+
+	* changes:		Updated for 8.5.2 release.
+
+	* doc/http.n:	Revised to indicate that [package require http 2.5.5]
+	is needed to get all the documented commands ([http::meta]).
+
+	* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd):	Added error
+	* tests/event.test (event-5.*):	checking to protect against callers
+	passing invalid return options dictionaries. [Bug 1901113]
+
+	* generic/tclBasic.c (ExprAbsFunc):	Revised so that the abs()
+	* tests/expr.test:	function and the [::tcl::mathfunc::abs]
+	command do not return the value of -0, or equivalent values with more
+	alarming string reps like -1e-350. [Bug 1893815]
+
+2008-03-07  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclResult.c (ReleaseKeys): Workaround for [Bug 1904907].
+	Reset the return option keys to NULL to allow full re-initialization
+	by GetKeys(). This introduces a memory leak for the key objects, but
+	gets us around a crash in the finalization of reflected channels when
+	handling returns, either at compile- or runtime. In both cases we
+	access the keys after they have been released by their thread exit
+	handler. A proper fix is entangled with the untangling of the
+	finalization ordering and attendant issues. For now we choose the
+	lesser evil.
+
+2008-03-07  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c (Tcl_ExprObj):	Revised expression bytecode
+	compiling so that bytecodes invalid due to changing context or due to
+	the difference between expressions and scripts are not reused. [Bug
+	1899164]
+
+	* generic/tclCmdAH.c:	Revised direct evaluation implementation of
+	[expr] so that [expr $e] caches compiled bytecodes for the expression
+	as the intrep of $e.
+
+	* tests/execute.test (execute-6.*):	More tests checking that
+	script bytecode is invalidated in the right situations.
+
+2008-03-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* win/configure.in: Add AC_HEADER_STDC to support msys/win64.
+
+2008-03-06  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/namespace.n: Minor tidying up. [Bug 1909019]
+
+2008-03-04  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/execute.test (6.3,4):	Added tests for [Bug 1899164].
+
+2008-03-03  Reinhard Max  <max@suse.de>
+
+	* unix/tclUnixChan.c: Fix mark and space parity on Linux, which uses
+	CMSPAR instead of PAREXT.
+
+2008-03-02  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclNamesp.c (GetNamespaceFromObj):
+	* tests/interp.test (interp-28.2): Spoil the intrep of an nsNameType
+	obj when the reference crosses interpreter boundaries.
+
+2008-02-29  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclResult.c (Tcl_SetReturnOptions):	Revised the refcount
+	management of Tcl_SetReturnOptions to become that of a conventional
+	Consumer routine. Thanks to Peter Spjuth for pointing out the
+	difficulties calling Tcl_SetReturnOptions with non-0-count value for
+	options.
+	* generic/tclExecute.c (INST_RETURN_STK): Revised the one caller
+	within Tcl itself which passes a non-0-count value to
+	Tcl_SetReturnOptions().
+
+	* generic/tclBasic.c (Tcl_AppendObjToErrorInfo):	Revised the
+	refcount management of Tcl_AppendObjToErrorInfo to become that of a
+	conventional Consumer routine. This preserves the ease of use for the
+	overwhelming common callers who pass in a 0-count value, but makes the
+	proper call with a non-0-count value less surprising.
+	* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd):	Revised the
+	one caller within Tcl itself which passes a non-0-count value to
+	Tcl_AppendObjToErrorInfo().
+
+2008-02-28  Joe English  <jenglish@users.sourceforge.net>
+
+	* unix/tclPort.h, unix/tclCompat.h, unix/tclUnixChan.h: Reduce scope
+	of <sys/filio.h> and <sys/ioctl.h> #includes. [Patch 1903339]
+
+2008-02-28  Joe English  <jenglish@users.sourceforge.net>
+
+	* unix/tclUnixChan.c, unix/tclUnixNotfy.c, unix/tclUnixPipe.c:
+	Consolidate all code conditionalized on -DUSE_FIONBIO into one place.

+	TclUnixSetBlockingMode(). [Patch 1903339]
+
+2008-02-28  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (TclEvalObjvInternal):	Plug memory leak when
+	an enter trace deletes or changes the command, prompting a reparsing.
+	Don't let the second pass lose commandPtr value allocated during the
+	first pass.
+
+	* generic/tclCompExpr.c (ParseExpr):	Plug memory leak in error
+	message generation.
+
+	* generic/tclStringObj.c (Tcl_AppendFormatToObj): [format %llx $big]
+	leaked an mp_int.
+
+	* generic/tclCompCmds.c (TclCompileReturnCmd):	The 2007-10-18 commit
+	to optimize compiled [return -level 0 $x] [RFE 1794073] introduced a
+	memory leak of the return options dictionary. Fixing that.
+
+2008-02-27  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* library/http/http.tcl: [Bug 705956] - fix inverted logic when
+	cleaning up socket error in geturl.
+
+2008-02-27  Kevin B. Kenny  <kennykb@acm.org>
+
+	* doc/clock.n: Corrected minor indentation gaffe in the penultimate
+	paragraph. [Bug 1898025]
+	* generic/tclClock.c (ParseClockFormatArgs): Changed to check that the
+	clock value is in the range of a 64-bit integer. [Bug 1862555]
+	* library/clock.tcl (::tcl::clock::format, ::tcl::clock::scan,
+	(::tcl::clock::add, ::tcl::clock::LocalizeFormat): Fixed bugs in
+	caching of localized strings that caused weird results when localized
+	date/time formats were used. [Bug 1902423]
+	* tests/clock.test (clock-61.*, clock-62.1): Regression tests for [Bug
+	1862555] and [Bug 1902423].
+
+2008-02-26  Joe English  <jenglish@users.sourceforge.net>
+
+	* generic/tclIOUtil.c, unix/tclUnixPort.h, unix/tclUnixChan.c:
+	Remove dead/unused portability-related #defines and unused conditional
+	code. See [Patch 1901828] for discussion.
+
+2008-02-26  Joe English  <jenglish@users.sourceforge.net>

+2008-02-26  Joe English  <jenglish@users.sourceforge.net>
+
+	* unix/configure.in(socklen_t test): Define socklen_t as "int" if

+	AC_EGREP_HEADER.
+	* unix/configure: regenerated.
+
+2008-02-26  Joe English  <jenglish@users.sourceforge.net>

+
+	* library/http/pkgIndex.tcl: Set version 2.5.5
+	* library/http/http.tcl:     It is better to do the [eof] check after

+2008-02-22  Pat Thoyts  <patthoyts@users.sourceforge.net>
+

+Recent user-visible changes to Tcl:
+
+1. No more [command1] [command2] construct for grouping multiple
+commands on a single command line.
+
+2. Semi-colon now available for grouping commands on a line.
+
+3. For a command to span multiple lines, must now use backslash-return
+at the end of each line but the last.
+
+4. "Var" command has been changed to "set".
+
+5. Double-quotes now available as an argument grouping character.
+
+6. "Return" may be used at top-level.
+
+7. More backslash sequences available now.  In particular, backslash-newline
+may be used to join lines in command files.
+
+8. New or modified built-in commands:  case, return, for, glob, info,
+print, return, set, source, string, uplevel.
+
+9. After an error, the variable "errorInfo" is filled with a stack
+trace showing what was being executed when the error occurred.
+
+10. Command abbreviations are accepted when parsing commands, but
+are not recommended except for purely-interactive commands.
+
+11. $, set, and expr all complain now if a non-existent variable is
+referenced.
+
+12. History facilities exist now.  See Tcl.man and Tcl_RecordAndEval.man.
+
+13. Changed to distinguish between empty variables and those that don't
+exist at all.  Interfaces to Tcl_GetVar and Tcl_ParseVar have changed
+(NULL return value is now possible).  *** POTENTIAL INCOMPATIBILITY ***
+
+14. Changed meaning of "level" argument to "uplevel" command (1 now means
+"go up one level", not "go to level 1"; "#1" means "go to level 1").
+*** POTENTIAL INCOMPATIBILITY ***
+
+15. 3/19/90 Added "info exists" option to see if variable exists.
+
+16. 3/19/90 Added "noAbbrev" variable to prohibit command abbreviations.
+
+17. 3/19/90 Added extra errorInfo option to "error" command.
+
+18. 3/21/90 Double-quotes now only affect space:  command, variable,
+and backslash substitutions still occur inside double-quotes.
+*** POTENTIAL INCOMPATIBILITY ***
+
+19. 3/21/90 Added support for \r.
+
+20. 3/21/90 List, concat, eval, and glob commands all expect at least
+one argument now.  *** POTENTIAL INCOMPATIBILITY ***
+
+21. 3/22/90 Added "?:" operators to expressions.
+
+22. 3/25/90 Fixed bug in Tcl_Result that caused memory to get trashed.
+
+------------------- Released version 3.1 ---------------------
+
+23. 3/29/90 Fixed bug that caused "file a.b/c ext" to return ".b/c".
+
+24. 3/29/90 Semi-colon is not treated specially when enclosed in
+double-quotes.
+
+------------------- Released version 3.2 ---------------------
+
+25. 4/16/90 Rewrote "exec" not to use select or signals anymore.
+Should be more Sys-V compatible, and no slower in the normal case.
+
+26. 4/18/90 Rewrote "glob" to eliminate GNU code (there's no GNU code
+left in Tcl, now), and added Tcl_TildeSubst procedure.  Added automatic
+tilde-substitution in many commands, including "glob".
+
+------------------- Released version 3.3 ---------------------
+
+27. 7/11/90 Added "Tcl_AppendResult" procedure.
+
+28. 7/20/90 "History" with no options now defaults to "history info"
+rather than to "history redo".  Although this is a backward incompatibility,
+it should only be used interactively and thus shouldn't present any
+compatibility problems with scripts.
+
+29. 7/20/90 Added "Tcl_GetInteger", "Tcl_GetDouble", and "Tcl_GetBoolean"
+procedures.
+
+30. 7/22/90 Removed "Tcl_WatchInterp" procedure:  doesn't seem to be
+necessary, since the same effect can be achieved with the deletion
+callbacks on individual commands.  *** POTENTIAL INCOMPATIBILITY ***
+
+31. 7/23/90 Added variable tracing:  Tcl_TraceVar, Tcl_UnTraceVar,
+and Tcl_VarTraceInfo procedures, "trace" command.
+
+32. 8/9/90 Mailed out list of all bug fixes since 3.3 release.
+
+33. 8/29/90 Fixed bugs in Tcl_Merge relating to backslashes and
+semi-colons.  Mailed out patch.
+
+34. 9/3/90 Fixed bug in tclBasic.c: quotes weren't quoting ]'s.
+Mailed out patch.
+
+35. 9/19/90 Rewrote exec to always use files both for input and
+output to the process.  The old pipe-based version didn't work if
+the exec'ed process forked a child and then exited:  Tcl waited
+around for stdout to get closed, which didn't happen until the
+grandchild exited.
+
+36. 11/5/90 ERR_IN_PROGRESS flag wasn't being cleared soon enough
+in Tcl_Eval, allowing error messages from different commands to
+pile up in $errorInfo.  Fixed by re-arranging code in Tcl_Eval that
+re-initializes result and ERR_IN_PROGRESS flag.  Didn't mail out
+patch:  changes too complicated to describe.
+
+37. 12/19/90 Added Tcl_VarEval procedure as a convenience for
+assembling and executing Tcl commands.
+
+38. 1/29/91 Fixed core leak in Tcl_AddErrorInfo.  Also changed procedure
+and Tcl_Eval so that first call to Tcl_AddErrorInfo need not come from
+Tcl_Eval.
+
+----------------- Released version 5.0 with Tk ------------------
+
+39. 4/3/91 Removed change bars from manual entries, leaving only those
+that came after version 3.3 was released.
+
+40. 5/17/91 Changed tests to conform to Mary Ann May-Pumphrey's approach.
+
+41. 5/23/91 Massive revision to Tcl parser to simplify the implementation
+of string and floating-point support in expressions.  Newlines inside
+[] are now treated as command separators rather than word separators
+(this makes newline treatment consistent throughout Tcl).
+*** POTENTIAL INCOMPATIBILITY ***
+
+42. 5/23/91 Massive rewrite of expression code to support floating-point
+values and simple string comparisons.  The C interfaces to expression
+routines have changed (Tcl_Expr is replaced by Tcl_ExprLong, Tcl_ExprDouble,
+etc.), but all old Tcl expression strings should be accepted by the new
+expression code.
+*** POTENTIAL INCOMPATIBILITY ***
+
+43. 5/23/91 Modified tclHistory.c to check for negative "keep" value.
+
+44. 5/23/91 Modified Tcl_Backslash to handle backslash-newline.  It now
+returns 0 to indicate that a backslash sequence should be replaced by
+no character at all.
+*** POTENTIAL INCOMPATIBILITY ***
+
+45. 5/29/91 Modified to use ANSI C function prototypes.  Must set
+"USE_ANSI" switch when compiling to get prototypes.
+
+46. 5/29/91 Completed test suite by providing tests for all of the
+built-in Tcl commands.
+
+47. 5/29/91 Changed Tcl_Concat to eliminate leading and trailing
+white-space in each of the things it concatenates and to ignore
+elements that are empty or have only white space in them.  This
+produces cleaner output from the "concat" command.
+*** POTENTIAL INCOMPATIBILITY ***
+
+48. 5/31/91 Changed "set" command and Tcl_SetVar procedure to return
+new value of variable.
+
+49. 6/1/91 Added "while" and "cd" commands.
+
+50. 6/1/91 Changed "exec" to delete the last character of program
+output if it is a newline.  In most cases this makes it easier to
+process program-generated output.
+*** POTENTIAL INCOMPATIBILITY ***
+
+51. 6/1/91 Made sure that pointers are never used after freeing them.
+
+52. 6/1/91 Fixed bug in TclWordEnd where it wasn't dealing with
+[] inside quotes correctly.
+
+53. 6/8/91 Fixed exec.test to accept return values of either 1 or
+255 from "false" command.
+
+54. 7/6/91 Massive overhaul of variable management.  Associative
+arrays now available, along with "unset" command (and Tcl_UnsetVar
+procedure).  Variable traces have been completely reworked:
+interfaces different both from Tcl and C, and multiple traces may
+exist on same variable.  Can no longer redefine existing local
+variable to be global.  Calling sequences have changed slightly
+for Tcl_GetVar and Tcl_SetVar ("global" is now "flags"). Tcl_SetVar
+can fail and return a NULL result.  New forms of variable-manipulation
+procedures:  Tcl_GetVar2, Tcl_SetVar2, etc.  Syntax of variable
+$-notation changed to support array indexing.
+*** POTENTIAL INCOMPATIBILITY ***
+
+55. 7/6/91 Added new list-manipulation procedures:  Tcl_ScanElement,
+Tcl_ConvertElement, Tcl_AppendElement.
+
+56. 7/12/91 Created new procedure Tcl_EvalFile, which does most of the
+work of the "source" command.
+
+57. 7/20/91 Major reworking of "exec" command to allow pipelines,
+more redirection, background.  Added new procedures Tcl_Fork,
+Tcl_WaitPids, Tcl_DetachPids, and Tcl_CreatePipeline.  The old
+"< input" notation has been replaced by "<< input" ("<" is for
+redirection from a file).  Also handles error returns and abnormal
+terminations (e.g. signals) differently.
+*** POTENTIAL INCOMPATIBILITY ***
+
+58. 7/21/91 Added "append" and "lappend" commands.
+
+59. 7/22/91 Reworked error messages and manual entries to use
+?x? as the notation for an optional argument x, instead of [x].  The
+bracket notation was often confused with the use of brackets for
+command substitution.  Also modified error messages to be more
+consistent.
+
+60. 7/23/91 Tcl_DeleteCommand now returns an indication of whether
+or not the command actually existed, and the "rename" command uses
+this information to return an error if an attempt is made to delete
+a non-existent command.
+*** POTENTIAL INCOMPATIBILITY ***
+
+61. 7/25/91 Added new "errorCode" mechanism, along with procedures
+Tcl_SetErrorCode, Tcl_UnixError, and Tcl_ResetResult.  Renamed
+Tcl_Return to Tcl_SetResult, but left a #define for Tcl_Return to
+avoid compatibility problems.
+
+62. 7/26/91 Extended "case" command with alternate syntax where all
+patterns and commands are together in a single list argument:  makes
+it easier to write multi-line case statements.
+
+63. 7/27/91 Changed "print" command to perform tilde-substitution on
+the file name.
+
+64. 7/27/91 Added "tolower", "toupper", "trim", "trimleft", and "trimright"
+options to "string" command.
+
+65. 7/29/91 Added "atime", "mtime", "size", and "stat" options to "file"
+command.
+
+66. 8/1/91 Added "split" and "join" commands.
+
+67. 8/11/91 Added commands for file I/O, including "open", "close",
+"read", "gets", "puts", "flush", "eof", "seek", and "tell".
+
+68. 8/14/91 Switched to use a hash table for command lookups.  Command
+abbreviations no longer have direct support in the Tcl interpreter, but
+it should be possible to simulate them with the auto-load features
+described below.  The "noAbbrev" variable is no longer used by Tcl.
+*** POTENTIAL INCOMPATIBILITY ***
+
+68.5 8/15/91 Added support for "unknown" command, which can be used to
+complete abbreviations, auto-load library files, auto-exec shell
+commands, etc.
+
+69. 8/15/91 Added -nocomplain switch to "glob" command.
+
+70. 8/20/91 Added "info library" option and TCL_LIBRARY #define.  Also
+added "info script" option.
+
+71. 8/20/91 Changed "file" command to take "option" argument as first
+argument (before file name), for consistency with other Tcl commands.
+*** POTENTIAL INCOMPATIBILITY ***
+
+72. 8/20/91 Changed format of information in $errorInfo variable:
+comments such as
+    ("while" body line 1)
+are now on separate lines from commands being executed.
+*** POTENTIAL INCOMPATIBILITY ***
+
+73. 8/20/91 Changed Tcl_AppendResult so that it (eventually) frees
+large buffers that it allocates.
+
+74. 8/21/91 Added "linsert", "lreplace", "lsearch", and "lsort"
+commands.
+
+75. 8/28/91 Added "incr" and "exit" commands.
+
+76. 8/30/91 Added "regexp" and "regsub" commands.
+
+77. 9/4/91 Changed "dynamic" field in interpreters to "freeProc" (procedure
+address).  This allows for alternative storage managers.
+*** POTENTIAL INCOMPATIBILITY ***
+
+78. 9/6/91 Added "index", "length", and "range" options to "string"
+command.  Added "lindex", "llength", and "lrange" commands.
+
+79. 9/8/91 Removed "index", "length", "print" and "range" commands.
+"Print" is redundant with "puts", but less general, and the other
+commands are replaced with the new commands described in change 78
+above.
+*** POTENTIAL INCOMPATIBILITY ***
+
+80. 9/8/91 Changed history revision to occur even when history command
+is nested;  needed in order to allow "history" to be invoked from
+"unknown" procedure.
+
+81. 9/13/91 Changed "panic" not to use vfprintf (it's uglier and less
+general now, but makes it easier to run Tcl on systems that don't
+have vfprintf).  Also changed "strerror" not to redeclare sys_errlist.
+
+82. 9/19/91 Lots of changes to improve portability to different UNIX
+systems, including addition of "config" script to adapt Tcl to the
+configuration of the system it's being compiled on.
+
+83. 9/22/91 Added "pwd" command.
+
+84. 9/22/91 Renamed manual pages so that their filenames are no more
+than 14 characters in length, moved to "doc" subdirectory.
+
+85. 9/24/91 Redid manual entries so they contain the supplemental
+macros that they need;  can just print with "troff -man" or "man"
+now.
+
+86. 9/26/91 Created initial version of script library, including
+a version of "unknown" that does auto-loading, auto-execution, and
+abbreviation expansion.  This library is used by tclTest
+automatically.  See the "library" manual entry for details.
+
+----------------- Released version 6.0, 9/26/91 ------------------
+
+87. 9/30/91 Made "string tolower" and "string toupper" check case
+before converting:  on some systems, "tolower" and "toupper" assume
+that character already has particular case.
+
+88. 9/30/91 Fixed bug in Tcl_SetResult:  wasn't always setting freeProc
+correctly when called with NULL value.  This tended to cause memory
+allocation errors later.
+
+89. 10/3/91 Added "upvar" command.
+
+90. 10/4/91 Changed "format" so that internally it converts %D to %ld,
+%U to %lu, %O to %lo, and %F to %f.  This eliminates some compatibility
+problems on some machines without affecting behavior.
+
+91. 10/10/91 Fixed bug in "regsub" that caused core dumps with the -all
+option when the last match wasn't at the end of the string.
+
+92. 10/17/91 Fixed problems with backslash sequences:  \r support was
+incomplete and \f and \v weren't supported at all.
+
+93. 10/24/91 Added Tcl_InitHistory procedure.
+
+94. 10/24/91 Changed "regexp" to store "-1 -1" in subMatchVars that
+don't match, rather than returning an error.
+
+95. 10/27/91 Modified "regexp" to return actual strings in matchVar
+and subMatchVars instead of indices.  Added "-indices" switch to cause
+indices to be returned.
+*** POTENTIAL INCOMPATIBILITY ***
+
+96. 10/27/91 Fixed bug in "scan" where it used hardwired constants for
+sizes of floats and doubles instead of using "sizeof".
+
+97. 10/31/91 Fixed bug in tclParse.c where parse-related error messages
+weren't being storage-managed correctly, causing spurious free's.
+
+98. 10/31/91 Form feed and vertical tab characters are now considered
+to be space characters by the parser.
+
+99. 10/31/91 Added TCL_LEAVE_ERR_MSG flag to procedures like Tcl_SetVar.
+
+100. 11/7/91 Fixed bug in "case" where "in" argument couldn't be omitted
+if all case branches were embedded in a single list.
+
+101. 11/7/91 Switched to use "pid_t" and "uid_t" and other official
+POSIC types and function prototypes.
+
+----------------- Released version 6.1, 11/7/91 ------------------
+
+102. 12/2/91 Modified Tcl_ScanElement and Tcl_ConvertElement in several
+ways.  First, allowed caller to request that only backslashes be used
+(no braces).  Second, made Tcl_ConvertElement more aggressive in using
+backslashes for braces and quotes.
+
+103. 12/5/91 Added "type", "lstat", and "readlink" options to "file"
+command, plus added new "type" element to output of "stat" and "lstat"
+options.
+
+104. 12/10/91 Manual entries had first lines that caused "man" program
+to try weird preprocessor.  Added blank comment lines to fix problem.
+
+105. 12/16/91 Fixed a few bugs in auto_mkindex proc:  wasn't handling
+errors properly, and hadn't been upgraded for new "regexp" syntax.
+
+106. 1/2/92 Fixed bug in "file" command where it didn't properly handle
+a file names containing tildes where the indicated user doesn't exist.
+
+107. 1/2/92 Fixed lots of cases in tclUnixStr.c where two different
+errno symbols (e.g. EWOULDBLOCK and EAGAIN) have the same number;  Tcl
+will only use one of them.
+
+108. 1/2/92 Lots of changes to configuration script to handle many more
+systems more gracefully.  E.g. should now detect the bogus strtoul that
+comes with AIX and substitute Tcl's own version instead.
+
+----------------- Released version 6.2, 1/10/92 ------------------
+
+109. 1/20/92 Config didn't have code to actually use "uid_t" variable
+to set TCL_UIT_T #define.
+
+110. 2/10/92 Tcl_Eval didn't properly reset "numLevels" variable when
+too-deep recursion occurred.
+
+111. 2/29/92 Added "on" and "off" to keywords accepted by Tcl_GetBoolean.
+
+112. 3/19/92 Config wasn't installing default version of strtod.c for
+systems that don't have one in libc.a.
+
+113. 3/23/92 Fixed bug in tclExpr.c where numbers with leading "."s,
+like 0.75, couldn't be properly substituted into expressions with
+variable or command substitution.
+
+114. 3/25/92 Fixed bug in tclUnixAZ.c where "gets" command wasn't
+checking to make sure that it was able to write the variable OK.
+
+115. 4/16/92 Fixed bug in tclUnixAZ.c where "read" command didn't
+compute file size right for device files.
+
+116. 4/23/92 Fixed but in tclCmdMZ.c where "trace vinfo" was overwriting
+the trace command.
+
+----------------- Released version 6.3, 5/1/92 ------------------
+
+117. 5/1/92 Added Tcl_GlobalEval.
+
+118. 6/1/92 Changed auto-load facility to source files at global level.
+
+119. 6/8/92 Tcl_ParseVar wasn't always setting termPtr after errors, which
+sometimes caused core dumps.
+
+120. 6/21/92 Fixed bug in initialization of regexp pattern cache.  This
+bug caused segmentation violations in regexp commands under some conditions.
+
+121. 6/22/92 Changed implementation of "glob" command to eliminate
+trailing slashes on directory names:  they confuse some systems.  There
+shouldn't be any user-visible changes in functionality except for names
+in error messages not having trailing slashes.
+
+122. 7/2/92 Fixed bug that caused 'string match ** ""' to return 0.
+
+123. 7/2/92 Fixed bug in Tcl_CreateCmdBuf where it wasn't initializing
+the buffer to an empty string.
+
+124. 7/6/92 Fixed bug in "case" command where it used NULL pattern string
+after errors in the "default" clause.
+
+125. 7/25/92 Speeded up auto_load procedure:  don't reread all the index
+files unless the path has changed.
+
+126. 8/3/92 Changed tclUnix.h to define MAXPATHLEN from PATH_MAX, not
+_POSIX_PATH_MAX.
+
+----------------- Released version 6.4, 8/7/92 ------------------
+
+127. 8/10/92 Changed tclBasic.c so that comment lines can be continued by
+putting a backslash before the newline.
+
+128. 8/21/92 Modified "unknown" to allow the source-ing of a file for
+an auto-load to trigger other nested auto-loads, as long as there isn't
+any recursion on the same command name.
+
+129. 8/25/92 Modified "format" command to allow " " and "+" flags, and
+allow flags in any order.
+
+130. 9/14/92 Modified Tcl_ParseVar so that it doesn't actually attempt
+to look up the variable if "noEval" mode is in effect in the interpreter
+(it just parses the name).  This avoids the errors that used to occur
+in statements like "expr {[info exists foo] && $foo}".
+
+131. 9/14/92 Fixed bug in "uplevel" command where it didn't output the
+correct error message if a level was specified but no command.
+
+132. 9/14/92 Renamed manual entries to have extensions like .3 and .n,
+and added "install" target to Makefile.
+
+133. 9/18/92 Modified "unknown" command to emulate !!, !<num>, and
+^<old>^<new> csh history substitutions.
+
+134. 9/21/92 Made the config script cleverer about figuring out which
+switches to pass to "nm".
+
+135. 9/23/92 Fixed tclVar.c to be sure to copy flags when growing variables.
+Used to forget about traces in progress and make extra recursive calls
+on trace procs.
+
+136. 9/28/92 Fixed bug in auto_reset where it was unsetting variables
+that might not exist.
+
+137. 10/7/92 Changed "parray" library procedure to print any array
+accessible to caller, local or global.
+
+138. 10/15/92 Fixed bug where propagation of new environment variable
+values among interpreters took N! time if there exist N interpreters.
+
+139. 10/16/92 Changed auto_reset procedure so that it also deletes any
+existing procedures that are in the auto_load index (the assumption is
+that they should be re-loaded to get the latest versions).
+
+140. 10/21/92 Fixed bug that caused lists to be incorrectly generated
+for elements that contained backslash-newline sequences.
+
+141. 12/9/92 Added support for TCL_LIBRARY environment variable:  use
+it as library location if it's present.
+
+142. 12/9/92 Added "info complete" command, Tcl_CommandComplete procedure.
+
+143. 12/16/92 Changed the Makefile to check to make sure "config" has been
+run (can't run config directly from the Makefile because it modifies the
+Makefile;  thus make has to be run again after running config).
+
+----------------- Released version 6.5, 12/17/92 ------------------
+
+144. 12/21/92 Changed config to look in several places for libc file.
+
+145. 12/23/92 Added "elseif" support to if.  Also, "then", "else", and
+"elseif" may no longer be abbreviated.
+*** POTENTIAL INCOMPATIBILITY ***
+
+146. 12/28/92 Changed "puts" and "read" to support initial "-nonewline"
+switch instead of additional "nonewline" argument.  The old form is
+still supported, but it is discouraged and is no longer documented.
+Also changed "puts" to make the file argument default to stdout: e.g.
+"puts foo" will print foo on standard output.
+
+147. 1/6/93 Fixed bug whereby backslash-newline wasn't working when
+typed interactively, or in "info complete".
+
+148. 1/22/93 Fixed bugs in "lreplace" and "linsert" where close
+quotes were being lost from last element before replacement or
+insertion.
+
+149. 1/29/93 Fixed bug in Tcl_AssembleCmd where it wasn't requiring
+a newline at the end of a line before considering a command to be
+complete.  The bug caused some very long lines in script files to
+be processed as multiple separate commands.
+
+150. 1/29/93 Various changes in Makefile to add more configuration
+options, simplify installation, fix bugs (e.g. don't use -f switch
+for cp), etc.
+
+151. 1/29/93 Changed "name1" and "name2" identifiers to "part1" and
+"part2" to avoid name conflicts with stupid C++ implementations that
+use "name1" and "name2" in a reserved way.
+
+152. 2/1/93 Added "putenv" procedure to replace the standard system
+version so that it will work correctly with Tcl's environment handling.
+
+----------------- Released version 6.6, 2/5/93 ------------------
+
+153. 2/10/93 Fixed bugs in config script:  missing "endif" in libc loop,
+and tried to use strncasecmp.c instead of strcasecmp.c.
+
+154. 2/10/93 Makefile improvements:  added RANLIB variable for easier
+Sys-V configuration, added SHELL variable for SGI systems.
+
+----------------- Released version 6.7, 2/11/93 ------------------
+
+153. 2/6/93 Changes in backslash processing:
+    - \Cx, \Mx, \CMx, \e sequences no longer special
+    - \<newline> also eats up any space after the newline, replacing
+      the whole sequence with a single space character
+    - Hex sequences like \x24 are now supported, along with ANSI C's \a.
+    - "format" no longer does backslash processing on its format string
+    - there is no longer any special meaning to a 0 return value from
+      Tcl_Backslash
+    - unknown backslash sequences, like (e.g. \*), are replaced with
+      the following character (e.g. *), instead of just treating the
+      backslash as an ordinary character.
+*** POTENTIAL INCOMPATIBILITY ***
+
+154. 2/6/93 Updated all copyright notices.  The meaning hasn't changed
+at all but the wording does a better job of protecting U.C. from
+liability (according to U.C. lawyers, anyway).
+
+155. 2/6/93 Changed "regsub" so that it overwrites the result variable
+in all cases, even if there is no match.
+*** POTENTIAL INCOMPATIBILITY ***
+
+156. 2/8/93 Added support for XPG3 %n$ conversion specifiers to "format"
+command.
+
+157. 2/17/93 Fixed bug in Tcl_Eval where errors due to infinite
+recursion could result in core dumps.
+
+158. 2/17/93 Improved the auto-load mechanism to deal gracefully (i.e.
+return an error) with a situation where a library file that supposedly
+defines a procedure doesn't actually define it.
+
+159. 2/17/93 Renamed Tcl_UnixError procedure to Tcl_PosixError, and
+changed errorCode variable usage to use POSIX as keyword instead of
+UNIX.
+*** POTENTIAL INCOMPATIBILITY ***
+
+160. 2/19/93 Changes to exec and process control:
+    - Added support for >>, >&, >>&, |&, <@, >@, and >&@ forms of redirection.
+    - When exec puts processes into background, it returns a list of
+      their pids as result.
+    - Added support for <file, >file, etc. (i.e. no space between
+      ">" and file name.
+    - Added -keepnewline option.
+    - Deleted Tcl_Fork and Tcl_WaitPids procedures (just use fork and
+      waitpid instead).
+    - Added waitpid compatibility procedure for systems that don't have
+      it.
+    - Added Tcl_ReapDetachedProcs procedure.
+    - Changed "exec" to return an error if there is stderr output, even
+      if the command returns a 0 exit status (it's always been documented
+      this way, but the implementation wasn't correct).
+    - If a process returns a non-zero exit status but doesn't generate
+      any diagnostic output, then Tcl generates an error message for it.
+*** POTENTIAL INCOMPATIBILITY ***
+
+161. 2/25/93 Fixed two memory-management problems having to do with
+managing the old result during variable trace callbacks.
+
+162. 3/1/93 Added dynamic string library:  Tcl_DStringInit, Tcl_DStringAppend,
+Tcl_DStringFree, Tcl_DStringResult, etc.
+
+163. 3/1/93 Modified glob command to only return the names of files that
+exist, and to only return names ending in "/" if the file is a directory.
+*** POTENTIAL INCOMPATIBILITY ***
+
+164. 3/19/93 Modified not to use system calls like "read" directly,
+but instead to use special Tcl procedures that retry automatically
+if interrupted by signals.
+
+165. 4/3/93 Eliminated "noSep" argument to Tcl_AppendElement, plus
+TCL_NO_SPACE flag for Tcl_SetVar and Tcl_SetVar2.
+*** POTENTIAL INCOMPATIBILITY ***
+
+166. 4/3/93 Eliminated "flags" and "termPtr" arguments to Tcl_Eval.
+*** POTENTIAL INCOMPATIBILITY ***
+
+167. 4/3/93 Changes to expressions:
+    - The "expr" command now accepts multiple arguments, which are
+      concatenated together with space separators.
+    - Integers aren't automatically promoted to floating-point if they
+      overflow the word size:  errors are generated instead.
+    - Tcl can now handle "NaN" and other special values if the underlying
+      library procedures handle them.
+    - When printing floating-point numbers, Tcl ensures that there is a "."
+      or "e" in the number, so it can't be treated as an integer accidentally.
+      The procedure Tcl_PrintDouble is available to provide this function
+      in other contexts.  Also, the variable "tcl_precision" can be used
+      to set the precision for printing (must be a decimal number giving
+      digits of precision).
+    - Expressions now support transcendental and other functions, e.g. sin,
+      acos, hypot, ceil, and round.  Can add new math functions with
+      Tcl_CreateMathFunc().
+    - Boolean expressions can now have any of the string values accepted
+      by Tcl_GetBoolean, such as "yes" or "no".
+*** POTENTIAL INCOMPATIBILITY ***
+
+168. 4/5/93 Changed Tcl_UnsetVar and Tcl_UnsetVar2 to return TCL_OK
+or TCL_ERROR instead of 0 or -1.
+*** POTENTIAL INCOMPATIBILITY ***
+
+169. 4/5/93 Eliminated Tcl_CmdBuf structure and associated procedures;
+can use Tcl_DStrings instead.
+*** POTENTIAL INCOMPATIBILITY ***
+
+170. 4/8/93 Changed interface to Tcl_TildeSubst to use a dynamic
+string for buffer space.  This makes the procedure re-entrant and
+thread-safe, whereas it wasn't before.
+*** POTENTIAL INCOMPATIBILITY ***
+
+171. 4/14/93 Eliminated tclHash.h, and moved everything from it to
+tcl.h
+*** POTENTIAL INCOMPATIBILITY ***
+
+172. 4/15/93 Eliminated Tcl_InitHistory, made "history" command always
+be part of interpreter.
+*** POTENTIAL INCOMPATIBILITY ***
+
+173. 4/16/93 Modified "file" command so that "readable" option always
+exists, even on machines that don't support symbolic links (always returns
+same error as if the file wasn't a symbolic link).
+
+174. 4/26/93 Fixed bugs in "regsub" where ^ patterns didn't get handled
+right (pretended not to match when it really did, and looped infinitely
+if -all was specified).
+
+175. 4/29/93 Various improvements in the handling of variables:
+    - Can create variables and array elements during a read trace.
+    - Can delete variables during traces (note: unset traces will be
+      invoked when this happens).
+    - Can upvar to array elements.
+    - Can retarget an upvar to another variable by re-issuing the
+      upvar command with a different "other" variable.
+
+176. 5/3/93 Added Tcl_GetCommandInfo, which returns info about a Tcl
+command such as whether it exists and its ClientData.  Also added
+Tcl_SetCommandInfo, which allows any of this information to be modified
+and also allows a command's delete procedure to have a different
+ClientData value than its command procedure.
+
+177. 5/5/93 Added Tcl_RegExpMatch procedure.
+
+178. 5/6/93 Fixed bug in "scan" where it didn't properly handle
+%% conversion specifiers.  Also changed "scan" to use Tcl_PrintDouble
+for printing real values.
+
+179. 5/7/93 Added "-exact", "-glob", and "-regexp" options to "lsearch"
+command to allow different kinds of pattern matching.
+
+180. 5/7/93 Added many new switches to "lsort" to control the sorting
+process: "-ascii", "-integer", "-real", "-command", "-increasing",
+and "-decreasing".
+
+181. 5/10/93 Changes to file I/O:
+    - Modified "open" command to support a list of POSIX access flags
+      like {WRONLY CREAT TRUNC} in addition to current fopen-style
+      access modes.  Also added "permissions" argument to set permissions
+      of newly-created files.
+    - Fixed Scott Bolte's bug (can close stdin etc. in application and
+      then re-open them with Tcl commands).
+    - Exported access to Tcl's file table with new procedures Tcl_EnterFile
+      and Tcl_GetOpenFile.
+
+182. 5/15/93 Added new "pid" command, which can be used to retrieve
+either the current process id or a list of the process ids in a
+pipeline opened with "open |..."
+
+183. 6/3/93 Changed to use GNU autoconfig for configuration instead of
+the home-brew "config" script.  Also made many other configuration-related
+changes, such as using <unistd.h> instead of explicitly declaring system
+calls in tclUnix.h.
+
+184. 6/4/93 Fixed bug where core-dumps could occur if a procedure
+redefined itself (the memory for the procedure's body could get
+reallocated in the middle of evaluating the body);  implemented
+simple reference count mechanism.
+
+185. 6/5/93 Changed tclIndex file format in two ways:  (a) it's now
+eval-ed instead of parsed, which makes it 3-4x faster; (b) the entries
+in auto_index are now commands to evaluate, which allows commands to
+be loaded in different ways such as dynamic-loading of C code.  The
+old tclIndex file format is still supported.
+
+186. 6/7/93 Eliminated tclTest program, added new "tclsh" program
+that is more like wish (allows script files to be invoked automatically
+using "#!/usr/local/bin/tclsh", makes arguments available to script,
+etc.).  Added support for Tcl_AppInit plus default version;  this
+allows new Tcl applications to be created without modifying the
+main program for tclsh.
+
+187. 6/7/93 Fixed bug in TclWordEnd that kept backslash-newline from
+working correctly in some cases during interactive input.
+
+188. 6/9/93 Added Tcl_LinkVar and related procedures, which automatically
+keep a Tcl variable in sync with a C variable.
+
+189. 6/16/93 Increased maximum nesting depth from 100 to 1000.
+
+190. 6/16/93 Modified "trace var" command so that error messages from
+within traces are returned properly as the result of the variable
+access, instead of the generic "access disallowed by trace command"
+message.
+
+191. 6/16/93 Added Tcl_CallWhenDeleted to provide callbacks when an
+interpreter is deleted (same functionality as Tcl_WatchInterp, which
+used to exist in versions before 6.0).
+
+193. 6/16/93 Added "-code" argument to "return" command;  it's there
+primarily for completeness, so that procedures implementing control
+constructs can reflect exceptional conditions back to their callers.
+
+194. 6/16/93 Split up Tcl.n to make separate manual entries for each
+Tcl command.  Tcl.n now contains a summary of the language syntax.
+
+195. 6/17/93 Added new "switch" command to replace "case": allows
+alternate forms of pattern matching (exact, glob, regexp), replaces
+pattern lists with single patterns (but you can use "-" bodies to
+share one body among several patterns), eliminates "in" noise word.
+"Case" command is now obsolete.
+
+196. 6/17/93 Changed the "exec", "glob", "regexp", and "regsub" commands
+to include a "--" switch.  All initial arguments starting with "-" are now
+treated as switches unless a "--" switch is present to end the list.
+*** POTENTIAL INCOMPATIBILITY ***
+
+197. 6/17/93 Changed auto-exec so that the subprocess gets stdin, stdout,
+and stderr from the parent.  This allows truly interactive sub-processes
+(e.g. vi) to be auto-exec'ed from a tcl shell command line.
+
+198. 6/18/93 Added patchlevel.h, for use in coordinating future patch
+releases, and also added "info patchlevel" command to make the patch
+level available to Tcl scripts.
+
+199. 6/19/93 Modified "glob" command so that a leading "//" in a name
+gets left as is (this is needed for systems like Apollos where "//" is
+the super-root;  Tcl used to collapse the two slashes into a single
+slash).
+
+200. 7/7/93 Added Tcl_SetRecursionLimit procedure so that the maximum
+allowable nesting depth can be controlled for an interpreter from C.
+
+----------------- Released version 7.0 Beta 1, 7/9/93 ------------------
+
+201. 7/12/93 Modified Tcl_GetInt and tclExpr.c so that full-precision
+unsigned integers can be specified without overflow errors.
+
+202. 7/12/93 Configuration changes:  eliminate leading blank line in
+configure script;  provide separate targets in Makefile for installing
+binary and non-binary information; check for size_t and a few other
+potentially missing typedefs; don't put tclAppInit.o into libtcl.a;
+better checks for matherr support.
+
+203. 7/14/93 Changed tclExpr.c to check the termination pointer before
+errno after strtod calls, to avoid problems with some versions of
+strtod that set errno in unexpected ways.
+
+204. 7/16/93 Changed "scan" command to be more ANSI-conformant:
+eliminated %F, %D, etc., added code to ignore "l", "h", and "L"
+modifiers but always convert %e, %f, and %g with implicit "l";
+also added support for %u and %i.  Also changed "format" command
+to eliminate %D, %U, %O, and add %i.
+*** POTENTIAL INCOMPATIBILITY ***
+
+205. 7/17/93 Changed "uplevel" and "upvar" so that they can be used
+from global level to global level:  this used to generate an error.
+
+206. 7/19/93 Renamed "setenv", "putenv", and "unsetenv" procedures
+to avoid conflicts with system procedures with the same names.  If
+you want Tcl's procedures to override the system procedures, do it
+in the Makefile (instructions are in the Makefile).
+*** POTENTIAL INCOMPATIBILITY ***
+
+----------------- Released version 7.0 Beta 2, 7/21/93 ------------------
+
+207. 7/21/93 Fixed bug in tclVar.c where freed memory was accidentally
+used if a procedure returned an element of a local array.
+
+208. 7/22/93 Fixed bug in "unknown" where it didn't properly handle
+errors occurring in the "auto_load" procedure, leaving its state
+inconsistent.
+
+209. 7/23/93 Changed exec's ">2" redirection operator to "2>" for
+consistency with sh.  This is incompatible with earlier beta releases
+of 7.0 but not with pre-7.0 releases, which didn't support either
+operator.
+
+210. 7/28/93 Changed backslash-newline handling so that the resulting
+space character *is* treated as a word separator unless the backslash
+sequence is in quotes or braces.  This is incompatible with 7.0b1
+and 7.0b2 but is more compatible with pre-7.0 versions that the b1
+and b2 releases were.
+
+211. 7/28/93 Eliminated Tcl_LinkedVarWritable, added TCL_LINK_READ_ONLY to
+Tcl_LinkVar to accomplish same purpose.  This change is incompatible
+with earlier beta releases, but not with releases before Tcl 7.0.
+
+212. 7/29/93 Renamed regexp C functions so they won't clash with POSIX
+regexp functions that use the same name.
+
+213. 8/3/93 Added "-errorinfo" and "-errorcode" options to "return"
+command: these allow for much better handling of the errorInfo
+and errorCode variables in some cases.
+
+214. 8/12/93 Changed "expr" so that % always returns a remainder with
+the same sign as the divisor and absolute value smaller than the
+divisor.
+
+215. 8/14/93 Turned off auto-exec in "unknown" unless the command
+was typed interactively.  This means you must use "exec" when
+invoking subprocesses, unless it's a command that's typed interactively.
+*** POTENTIAL INCOMPATIBILITY ***
+
+216. 8/14/93 Added support for tcl_prompt1 and tcl_prompt2 variables
+to tclMain.c:  makes prompts user-settable.
+
+217. 8/14/93 Added asynchronous handlers (Tcl_AsyncCreate etc.) so
+that signals can be taken cleanly by Tcl applications.
+
+218. 8/16/93 Moved information about open files from the interpreter
+structure to global variables so that a file can be opened in one
+interpreter and read or written in another.
+
+219. 8/16/93 Removed ENV_FLAGS from Makefile, so that there's no
+official support for overriding setenv, unsetenv, and putenv.
+
+220. 8/20/93 Various configuration improvements:  coerce chars
+to unsigned chars before using macros like isspace;  source ~/.tclshrc
+file during initialization if it exists and program is running
+interactively;  allow there to be directories in auto_path that don't
+exist or don't have tclIndex files (ignore them); added Tcl_Init
+procedure and changed Tcl_AppInit to call it.
+
+221. 8/21/93 Fixed bug in expr where "+", "-", and " " were all
+getting treated as integers with value 0.
+
+222. 8/26/93 Added "tcl_interactive" variable to tclsh.
+
+223. 8/27/93 Added procedure Tcl_FilePermissions to return whether a
+given file can be read or written or both.  Modified Tcl_EnterFile
+to take a permissions mask rather than separate read and write arguments.
+
+224. 8/28/93 Fixed performance bug in "glob" command (unnecessary call
+to "access" for each file caused a 5-10x slow-down for big directories).
+
+----------------- Released version 7.0 Beta 3, 8/28/93 ------------------
+
+225. 9/9/93 Renamed regexp.h to tclRegexp.h to avoid conflicts with system
+include file by same name.
+
+226. 9/9/93 Added Tcl_DontCallWhenDeleted.
+
+227. 9/16/93 Changed not to call exit C procedure directly;  instead
+always invoke "exit" Tcl command so that application can redefine the
+command to do additional cleanup.
+
+228. 9/17/93 Changed auto-exec to handle names that contain slashes
+(i.e. don't use PATH for them).
+
+229. 9/23/93 Fixed bug in "read" and "gets" commands where they didn't
+clear EOF conditions.
+
+----------------- Released version 7.0, 9/29/93 ------------------
+
+230. 10/7/93 "Scan" command wasn't properly aligning things in memory,
+so segmentation faults could arise under some circumstances.
+
+231. 10/7/93 Fixed bug in Tcl_ConvertElement where it forgot to
+backslash leading curly brace when creating lists.
+
+232. 10/7/93 Eliminated dependency of tclMain.c on tclInt.h and
+tclUnix.h, so that people can copy the file out of the Tcl source
+directory to make modified private versions.
+
+233. 10/8/93 Fixed bug in auto-loader that reversed the priority order
+of entries in auto_path for new-style index files.  Now things are
+back to the way they were before 3.0:  first in auto_path is always
+highest priority.
+
+234. 10/13/93 Fixed bug where Tcl_CommandComplete didn't recognize
+comments and treat them as such.  Thus if you typed the line
+    # {
+interactively, Tcl would think that the command wasn't complete and
+wait for more input before evaluating the script.
+
+235. 10/14/93 Fixed bug where "regsub" didn't set the output variable
+if the input string was empty.
+
+236. 10/23/93 Fixed bug where Tcl_CreatePipeline didn't close off enough
+file descriptors in child processes, causing children not to exit
+properly in some cases.
+
+237. 10/28/93 Changed "list" and "concat" commands not to generate
+errors if given zero arguments, but instead to just return an empty
+string.
+
+----------------- Released version 7.1, 11/4/93 ------------------
+
+Note: there is no 7.2 release.  It was flawed and was thus withdrawn
+shortly after it was released.
+
+238. 11/10/93 TclMain.c didn't compile on some systems because of
+R_OK in call to "access".  Changed to eliminate call to "access".
+
+----------------- Released version 7.3, 11/26/93 ------------------
+
+239. 11/6/93 Modified "lindex", "linsert", "lrange", and "lreplace"
+so that "end" can be specified as an index.
+
+240. 11/6/93 Modified "append" and "lappend" to allow only two
+words total (i.e., nothing to append) without generating an error.
+
+241. 12/2/93 Changed to use EAGAIN as the errno for non-blocking
+I/O instead of EWOULDBLOCK:  this should fix problem where non-blocking
+I/O didn't work correctly on System-V systems.
+
+242. 12/22/93 Fixed bug in expressions where cancelled evaluation
+wasn't always working correctly (e.g. "set one 1; eval {1 || 1/$one}"
+failed with a divide by zero error).
+
+243. 1/6/94 Changed TCL_VOLATILE definition from -1 to the address of
+a dummy procedure Tcl_Volatile, since -1 causes portability problems on
+some machines (e.g., Crays).
+
+244. 2/4/94 Added support for unary plus.
+
+245. 2/17/94 Changed Tcl_RecordAndEval and "history" command to
+call Tcl_GlobalEval instead of Tcl_Eval.  Otherwise, invocation of
+these facilities in nested procedures can cause unwanted results.
+
+246. 2/17/94 Fixed bug in tclExpr.c where an expression such as
+"expr {"12398712938788234-1298379" != ""}" triggers an integer
+overflow error for the number in quotes, even though it isn't really
+a proper integer anyway.
+
+247. 2/19/94 Added new procedure Tcl_DStringGetResult to move result
+from interpreter to a dynamic string.
+
+248. 2/19/94 Fixed bug in Tcl_DStringResult that caused it to overwrite
+the contents of a static result in some situations.  This can cause
+bizarre errors such as variables suddenly having empty values.
+
+249. 2/21/94 Fixed bug in Tcl_AppendElement, Tcl_DStringAppendElement,
+and the "lappend" command that caused improper omission of a separator
+space in some cases.  For example, the script
+    set x "abc{"; lappend x "def"
+used to return the result "abc{def" instead of "abc{ def".
+
+250. 3/3/94 Tcl_ConvertElement was outputting empty elements as \0 if
+TCL_DONT_USE_BRACES was set.  This depends on old pre-7.0 meaning of
+\0, which is no longer in effect, so it didn't really work.  Changed
+to output empty elements as {} always.
+
+251. 3/3/94 Renamed Tcl_DStringTrunc to Tcl_DStringSetLength and extended
+it so that it can be used to lengthen a string as well as shorten it.
+Tcl_DStringTrunc is defined as a macro for backward compatibility, but
+it is deprecated.
+
+252. 3/3/94 Added Tcl_AllowExceptions procedure.
+
+253. 3/13/94 Fixed bug in Tcl_FormatCmd that could cause "format"
+to mis-behave on 64-bit Big-Endian machines.
+
+254. 3/13/94 Changed to use vfork instead of fork on systems where
+vfork exists.
+
+255. 3/23/94 Fixed bug in expressions where ?: didn't associate
+right-to-left as they should.
+
+256. 4/3/94 Fixed "exec" to flush any files used in >@ or >&@
+redirection in exec, so that data buffered for them is written
+before any new data added by the subprocess.
+
+257. 4/3/94 Added "subst" command.
+
+258. 5/20/94 The tclsh main program is now called Tcl_Main;  tclAppInit.c
+has a "main" procedure that calls Tcl_Main.  This makes it easier to use
+Tcl with C++ programs, which need their own main programs, and it also
+allows an application to prefilter the argument list before calling
+Tcl_Main.
+*** POTENTIAL INCOMPATIBILITY ***
+
+259. 6/6/94 Fixed bug in procedure returns where the errorInfo variable
+could get truncated if an unset trace was invoked as part of returning
+from the procedure.
+
+260. 6/13/94 Added "wordstart" and "wordend" options to "string" command.
+
+261. 6/27/94 Fixed bug in expressions where they didn't properly cancel
+the evaluation of math functions in &&, ||, and ?:.
+
+262. 7/11/94 Incorrect boolean values, like "ogle", weren't being
+handled properly.
+
+263. 7/15/94 Added Tcl_RegExpCompile, Tcl_RegExpExec, and Tcl_RegExpRange,
+which provide lower-level access to regular expression pattern matching.
+
+264. 7/22/94 Fixed bug in "glob" command where "glob -nocomplain ~bad_user"
+would complain about a missing user.  Now it doesn't complain anymore.
+
+265. 8/4/94 Fixed bug with linked variables where they didn't behave
+correctly when accessed via upvars.
+
+266. 8/17/94 Fixed bug in Tcl_EvalFile where it didn't clear interp->result.
+
+267. 8/31/94 Modified "open" command so that errors in exec-ing
+subprocesses are returned by the open immediately, rather than
+being delayed until the "close" is executed.
+
+268. 9/9/94 Modified "expr" command to generate errors for integer
+overflow (includes addition, subtraction, negation, multiplication,
+division).
+
+269. 9/23/94 Modified "regsub" to return a count of the number of
+matches and replacements, rather than 0/1.
+
+279. 10/4/94 Added new features to "array" command:
+    - added "get" and "set" commands for easy conversion between arrays
+      and lists.
+    - added "exists" command to see if a variable is an array, changed
+      "names" and "size" commands to treat a non-existent array (or scalar
+      variable) just like an empty one.
+    - added pattern option to "names" command.
+
+280. 10/6/94 Modified Tcl_SetVar2 so that read traces on variables get
+called during append operations.
+
+281. 10/20/94 Fixed bug in "read" command where reading from stdin
+required two control-D's to stop the reading.
+
+282. 11/3/94 Changed "expr" command to use longs for division just like
+all other expr operators;  it previously used ints for division.
+
+283. 11/4/94 Fixed bugs in "unknown" procedure:  it wasn't properly
+handling exception returns from commands that were executed after
+being auto-loaded.
+
+----------------- Released version 7.4b1, 12/23/94 ------------------
+
+284. 12/26/94 Fixed "install" target in Makefile (couldn't always
+find install program).
+
+285. 12/26/94 Added strcncasecmp procedure to compat directory.
+
+286. 1/3/95 Fixed all procedure calls to explicitly cast arguments:
+implicit conversions from prototypes (especially integer->double)
+don't work when compiling under non-ANSI compilers.  Tcl is now clean
+under gcc -Wconversion.
+
+287. 1/4/95 Fixed problem in Tcl_ArrayCmd where same name was used for
+both a label and a variable;  caused problems on several older compilers,
+making array command misbehave and causing many errors in Tcl test suite.
+
+----------------- Released version 7.4b2, 1/12/95 ------------------
+
+288. 2/9/95 Modified Tcl_CreateCommand to return a token, and added
+Tcl_GetCommandName procedure.  Together, these procedures make it possible
+to track renames of a command.
+
+289. 2/13/95 Fixed bug in expr where "089" was interpreted as a
+floating-point number rather than a bogus octal number.
+*** POTENTIAL INCOMPATIBILITY ***
+
+290. 2/14/95 Added code to Tcl_GetInt and Tcl_GetDouble to check for
+overflows when reading in numbers.
+
+291. 2/18/95 Changed "array set" to stop after first error, rather than
+continuing after error.
+
+292. 2/20/95 Upgraded to use autoconf version 2.2.
+
+293. 2/20/95 Fixed core dump that could occur in "scan" command if a
+close bracket was omitted.
+
+294. 2/27/95 Changed Makefile to always use install-sh for installations:
+there's just too much variation among "install" system programs, which
+makes installation flakey.
+
+----------------- Released version 7.4b3, 3/24/95 ------------------
+
+3/25/95 (bug fix) Changed "install" to "./install" in Makefile so that
+"make install" will work even when "." isn't in the search path.
+
+3/29/95 (bug fix) Fixed bug where the auto-loading mechanism wasn't
+protecting the values of the errorCode and errorInfo variables.
+
+3/29/95 (new feature) Added optional pattern argument to "parray" procedure.
+
+3/29/95 (bug fix) Made the full functionality of
+    "return -code ... -errorcode ..."
+work not just inside procedures, but also in sourced files and at
+top level.
+
+4/6/95 (new feature) Added "pattern" option to "array names" command.
+
+4/18/95 (bug fix) Fixed bug in parser where it didn't allow backslash-newline
+immediately after an argument in braces or quotes.
+
+4/19/95 (new feature) Added tcl_library variable, which application can
+set to override default library directory.
+
+4/30/95 (bug fix) During trace callbacks for array elements, the variable
+name used in the original reference would be temporarily modified to
+separate the array name and element name;  if the trace callback used
+the same name string, it would get the wrong name (the array name without
+element).  Fixed to restore the variable name before making trace
+callbacks.
+
+4/30/95 (new feature) Added -nobackslashes, -nocommands, and -novariables
+switches to "subst" command.
+
+5/4/95 (new feature) Added TCL_EVAL_GLOBAL flag to Tcl_RecordAndEval.
+
+5/5/95 (bug fix)  Format command would overrun memory when printing
+integers with very large precision, as in "format %.1000d 0".
+
+5/5/95 (portability improvement) Changed to use BSDgettimeofday on
+IRIX machines, to avoid compilation problems with the gettimeofday
+declaration.
+
+5/6/95 (bug fix) Changed manual entries to use the standard .TH
+macro instead of a custom .HS macro;  the .HS macro confuses index
+generators like makewhatis.
+
+5/9/95 (bug fix) Modified configure script to check for Solaris bug
+that makes vfork unreliable (core dumps result if vforked child
+changes a signal handler);  will use fork instead of vfork if the
+bug is present.
+
+6/5/95 (bug fix) Modified "lsort" command to disallow recursive calls
+to lsort from a comparison function.  This is needed because qsort
+is not reentrant.
+
+6/5/95 (bug fix) Undid change 243 above:  changed TCL_VOLATILE and
+TCL_DYNAMIC back to integer constants rather than procedure addresses.
+This was needed because procedure addresses can have multiple values
+under some dynamic loading systems (e.g. SunOS 4.1 and Windows).
+
+6/8/95 (feature change) Modified interface to Tcl_Main to pass in the
+address of the application-specific initialization procedure.
+Tcl_AppInit is no longer hardwired into Tcl_Main.  This is needed
+in order to make Tcl a shared library.
+
+6/8/95 (feature change) Modified Makefile so that the installed versions
+of tclsh and libtcl.a have version number in them (e.g. tclsh7.4 and
+libtcl7.4.a) and the library directory name also has an embedded version
+number (e.g., /usr/local/lib/tcl7.4).  This should make it easier for
+Tcl 7.4 to coexist with earlier versions.
+
+----------------- Released version 7.4b4, 6/16/95 ------------------
+
+6/19/95 (bug fix) Fixed bugs in tclCkalloc.c that caused core dumps
+if TCL_MEM_DEBUG was enabled on word-addressed machines such as Crays.
+
+6/21/95 (feature removal) Removed overflow checks for integer arithmetic:
+they just cause too much trouble (e.g. for random  number generators).
+
+6/28/95 (new features) Added tcl_patchLevel and tcl_version variables,
+for consistency with Tk.
+
+6/29/95 (bug fix) Fixed problem in Tcl_Eval where it didn't record
+the right termination character if a script ended with a comment.  This
+caused erroneous output for the following command, among others:
+puts "[
+expr 1+1
+# duh!
+]"
+
+6/29/95 (message change) Changed the error message for ECHILD slightly
+to provide a hint about why the problem is occurring.
+
+----------------- Released version 7.4, 7/1/95 ------------------
+
+7/18/95 (bug fix) Changed "lreplace" so that nothing is deleted if
+the last index is less than the first index or if the last index
+is < 0.
+
+7/18/95 (bug fix) Fixed bugs with backslashes in comments:
+Tcl_CommandComplete (and "info complete") didn't properly handle
+strings ending in backslash-newline, and neither Tcl_CommandComplete
+nor the Tcl parser handled other backslash sequences right, such
+as two backslashes before a newline.
+
+7/19/95 (bug fix) Modified Tcl_DeleteCommand to delete the hash table
+entry for the command before invoking its callback.  This is needed in
+order to deal with reentrancy.
+
+7/22/95 (bug fix) "exec" wasn't reaping processes correctly after
+certain errors (e.g. if the name of the executable was bogus, as
+in "exec foobar").
+
+7/27/95 (bug fix) Makefile.in wasn't using the LIBS variable provided
+by the "configure" script.  This caused problems on some SCO systems.
+
+7/27/95 (bug fix) The version of strtod in fixstrtod.c didn't properly
+handle the case where endPtr == NULL.
+
+----------------- Released patch 7.4p1, 7/29/95 -----------------------
+
+8/4/95 (bug fix) C-level trace callbacks for variables were sometimes
+receiving the PART1_NOT_PARSED flag, which could cause errors in
+subsequent Tcl library calls using the flags. (JO)
+
+8/4/95 (bug fix) Calls to toupper and tolower weren't using the
+UCHAR macros, which caused trouble in non-U.S. locales. (JO)
+
+8/10/95 (new feature) Added the "load" command for dynamic loading of
+binary packages, and the Tcl_PackageInitProc prototype for package
+initialization procedures. (JO)
+
+8/23/95 (new features) Added "info sharedlibextension" and
+"info nameofexecutable" commands, plus Tcl_FindExtension procedure. (JO)
+
+8/25/95 (bug fix) If the target of an "upvar" was non-existent but
+had traces set, the traces were silently lost.  Change to generate
+an error instead. (JO)
+
+8/25/95 (bug fix) Undid change from 7/19, so that commands can stay
+around while their deletion callbacks execute.  Added lots of code to
+handle all of the reentrancy problems that this opens up. (JO)
+
+8/25/95 (bug fix) Fixed core dump that could occur in TclDeleteVars
+if there was an upvar from one entry in the table to the next entry
+in the same table. (JO)
+
+8/28/95 (bug fix) Exec wasn't handling bad user names properly, as
+in "exec ~bogus_user/foo". (JO)
+
+8/29/95 (bug fixes) Changed backslash-newline handling to correct two
+problems:
+    - Only spaces and tabs following the backslash-newline are now
+      absorbed as part of the backslash-newline.  Newlinew are no
+      longer absorbed (add another backslash if you want to absorb
+      another newline).
+    - TclWordEnd returns the character just before the backslash in
+      the sequence as the end of the sequence;  it used to not consider
+      the backslash-newline as a word separator. (JO)
+
+8/31/95 (new feature) Changed man page installation (with "mkLinks"
+script) to create additional links for manual pages corresponding to
+each of the procedure and command names described in the pages. (JO)
+
+9/10/95 Reorganized Tcl sources for Windows and Mac ports.  All sources
+are now in subdirectories:  "generic" contains sources that work on all
+platforms, "windows", "mac", and "unix" directories contain platform-
+specific sources.  Some UNIX sources are also used on other platforms. (SS)
+
+9/10/95 (feature change) Eliminated exported global variables (they
+don't work with Windows DLLs).  Replaced tcl_AsyncReady and
+tcl_FileCloseProc with procedures Tcl_AsyncReady() and
+Tcl_SetFileCloseProc().  Replaced C variable tcl_RcFileName with
+a Tcl variable tcl_rcFileName. (SS)
+*** POTENTIAL INCOMPATIBILITY ***
+
+9/11/95 (new feature) Added procedure Tcl_SetPanicProc to override
+the default implementation of "panic". (SS)
+
+9/11/95 (new feature) Added "interp" command to allow creation of
+new interpreters and execution of untrusted scripts.  Added many new
+procedures, such as Tcl_CreateSlave, Tcl_CreateAlias,and Tcl_MakeSafe,
+to provide C-level access to the interpreter facility. This mechanism
+now provides almost all of the generic functions of Borenstein's and
+Rose's Safe-Tcl (but not any Tk or email-related stuff).  (JL)
+
+9/11/95 (feature change) Changed file management so that files are
+no longer shared between interpreters:  a file cannot normally be
+referenced in one interpreter if it was opened in another.  This
+feature is needed to support safe interpreters.  Added Tcl_ShareHandle()
+procedure for allowing files to be shared, and added "interp" argument
+to Tcl_FilePermissions procedure. (JL)
+*** POTENTIAL INCOMPATIBILITY ***
+
+9/11/95 (new feature) Added "AssocData" mechanism, whereby extensions
+can associate their own data with an interpreter and get called back
+when the interpreter is deleted.  This is visible at C level via the
+procedures Tcl_SetAssocData and Tcl_GetAssocData.  (JL)
+
+9/11/95 (new feature) Added Tcl_ErrnoMsg to translate an errno value
+into a human-readable string.  This is now used instead of calling
+strerror because strerror mesages vary dramatically from platform
+to platform, which messes up Tcl tests.  Tcl_ErrnoMsg uses the standard
+POSIX messages for all the common signals, and calls strerror for
+signals it doesn't understand.
+
+----------------- Released patch 7.4p2, 9/15/95 -----------------------
+
+----------------- Released 7.5a1, 9/15/95 -----------------------
+
+9/22/95 (bug fix) Changed auto_mkindex to create tclIndex files that
+handle directories whose paths might contain spaces. (RJ)
+
+9/27/95 (bug fix) The "format" command didn't check for huge or negative
+width specifiers, which could cause core dumps. (JO)
+
+9/27/95 (bug fix) Core dumps could occur if an interactive command typed
+to tclsh returned a very long result for tclsh to print out.  The bug is
+actually in printf (in Solaris 2.3 and 2.4, at least);  switched to use
+puts instead.  (JO)
+
+9/28/95 (bug fix) Changed makefile.bc to eliminate a false dependency
+for tcl1675.dll on the Borland run time library. (SS)
+
+9/28/95 (bug fix) Fixed tcl75.dll so it looks for tcl1675.dll instead
+of tcl16.dll. (SS)
+
+9/28/95 (bug fix) Tcl was not correctly detecting the difference
+between Win32s and Windows '95. (SS)
+
+9/28/95 (bug fix) "exec" was not passing environment changes to child
+processes under Windows. (SS)
+
+9/28/95 (bug fix) Changed Tcl to ensure that open files are not passed
+to child processes under Windows. (SS)
+
+9/28/95 (bug fix) Fixed Windows '95 and NT versions of exec so it can
+handle both console and windows apps.   (SS)
+
+9/28/95 (bug fix) Fixed Windows version of exec so it no longer leaves
+temp files lying around.  Also changed it so the temp files are
+created in the appropriate system dependent temp directory. (SS)
+
+9/28/95 (bug fix) Eliminated source dependency on the Win32s Universal
+Thunk header file, since it is not bundled with VC++. (SS)
+
+9/28/95 (bug fix) Under Windows, Tcl now constructs the HOME
+environment variable from HOMEPATH and HOMEDRIVE when HOME is not
+already set. (SS)
+
+9/28/95 (bug fix) Added support for "info nameofexecutable" and "info
+sharedlibextension" to the Windows version. (SS)
+
+9/28/95 (bug fix) Changed tclsh to correctly parse command line
+arguments so that backslashes are preserved under Windows. (SS)
+
+9/29/95 (bug fix) Tcl 7.5a1 treated either return or newline as end
+of line in "gets", which caused lines ending in CRLF to be treated as
+two separate lines.  Changed to allow only character as end-of-line:
+carriage return on Macs, newline elsewhere. (JO)
+
+9/29/95 (new feature) Changed to install "configInfo" file in same
+directory as library scripts.  It didn't used to get installed. (JO)
+
+9/29/95 (bug fix) Tcl was not converting Win32 errors into POSIX
+errors under some circumstances. (SS)
+
+10/2/95 (bug fix) Safe interpreters no longer get initialized with
+a call to Tcl_Init(). (JL)
+
+10/1/95 (new feature) Added "tcl_platform" global variable to provide
+environment information such as the instruction set and operating
+system. (JO)
+
+10/1/95 (bug fix) "exec" command wasn't always generating the
+"child process exited abnormally" message when it should have.  (JO)
+
+10/2/95 (bug fix) Changed "mkLinks.tcl" so that the scripts it generates
+won't create links that overwrite original manual entries (there was
+a problem where pack-old.n was overwriting pack.n).  (JO)
+
+10/2/95 (feature change) Changed to use -ldl for dynamic loading under
+Linux if it is available, but fall back to -ldld if it isn't.  (JO)
+
+10/2/95 (bug fix) File sharing was causing refcounts to reach 0
+prematurely for stdin, stdout and stderr, under some circumstances. (JL)
+
+10/2/95 (platform support) Added support for Visual C++ compiler on
+Windows, Windows '95 and Windows NT, code donated by Gordon Chaffee. (JL)
+
+10/3/95 (bug fix) Tcl now frees any libraries that it loads before it
+exits. (SS)
+
+10/03/95 (bug fix) Fixed bug in Macintosh ls command where the -l
+and -C options would fail in anything but the HOME directory. (RJ)
+
+----------------- Released 7.5a2, 10/6/95 -----------------------
+
+10/10/95 (bug fix) "file dirnam /." was returning ":" on UNIX instead
+of "/". (JO)
+
+10/13/95 (bug fix) Eliminated dependency on MKS toolkit for generating
+the tcl.def file from Borland object files. (SS)
+
+10/17/95 (new features) Moved the event loop from Tcl to Tk, made major
+revisions along the way:
+    - New Tcl commands:  after, update, vwait (replaces "tkwait variable").
+    - "tkerror" is now replaced with "bgerror".
+    - The following procedures are similar to their old Tk counterparts:
+      Tcl_DoOneEvent, Tcl_Sleep, Tcl_DoWhenIdle, Tcl_CancelIdleCall,
+      Tcl_CreateFileHandler, Tcl_DeleteFileHandler, Tcl_CreateTimerHandler,
+      Tcl_DeleteTimerHandler, Tcl_BackgroundError.
+    - Revised notifier, add new concept of "event source" with the following
+      procedures:  Tcl_CreateEventSource, Tcl_DeleteEventSource,
+      Tcl_WatchFile, Tcl_SetMaxBlockTime, Tcl_FileReady, Tcl_QueueEvent,
+      Tcl_WaitForEvent. (JO)
+
+10/31/95 (new features) Implemented cross platform file name support to make
+it easier to write cross platform scripts.  Tcl now understands 4 file naming
+conventions: Windows (both DOS and UNC), Mac, Unix, and Network.  The network
+convention is a new naming mechanism that can be used to paths in a platform
+independent fashion.  See the "file" command manual page for more details.
+The primary interfaces changes are:
+    - All Tcl commands that expect a file name now accept both network and
+      native form.
+    - Two new "file" subcommands, "nativename" and "networkname", provide a
+      way to convert between network and native form.
+    - Renamed Tcl_TildeSubst to Tcl_TranslateFileName, and changed it so that
+      it always returns a filename in native form.  Tcl_TildeSubst is defined
+      as a macro for backward compatibility, but it is deprecated. (SS)
+
+11/5/95 (new feature) Made "tkerror" and "bgerror" synonyms, so that
+either name can be used to manipulate the command (provides temporary
+backward compatibility for existing scripts that use tkerror). (JO)
+
+11/5/95 (new feature) Added exit handlers and new C procedures
+Tcl_CreateExitHandler, Tcl_DeleteExitHandler, and Tcl_Exit. (JO)
+
+11/6/95 (new feature) Added pid command for Macintosh version of
+Tcl (it didn't previously exist on the Mac). (RJ)
+
+11/7/95 (new feature) New generic IO facility and support for IO to
+files, pipes and sockets based on a common buffering scheme. Support
+for asynchronous (non-blocking) IO and for event driver IO. Support
+for automatic (background) asynchronous flushing and asynchronous
+closing of channels. (JL)
+
+11/7/95 (new feature)  Added new commands "fconfigure" and "fblocked"
+to support new I/O features such as nonblocking I/O.  Added "socket"
+command for creating TCP client and server sockets. (JL).
+
+11/7/95 (new feature) Complete set of C APIs to the new generic IO
+facility:
+    - Opening channels: Tcl_OpenFileChannel, Tcl_OpenCommandChannel,
+      Tcl_OpenTcpClient, Tcl_OpenTcpServer.
+    - I/O procedures on channels, which roughly mirror the ANSI C stdio
+      library:  Tcl_Read, Tcl_Gets, Tcl_Write, Tcl_Flush, Tcl_Seek,
+      Tcl_Tell, Tcl_Close, Tcl_Eof, Tcl_InputBlocked, Tcl_GetChannelOption,
+      Tcl_SetChannelOption.
+    - Extension mechanism for creating new kinds of channels:
+      Tcl_CreateChannel, Tcl_GetChannelInstanceData, Tcl_GetChannelType,
+      Tcl_GetChannelName, Tcl_GetChannelFile, Tcl_RegisterChannel,
+      Tcl_UnregisterChannel, Tcl_GetChannel.
+    - Event-driven I/O on channels: Tcl_CreateChannelHandler,
+      Tcl_DeleteChannelHandler. (JL)
+
+11/7/95 (new feature) Channel driver interface specification to allow
+new types of channels to be added easily to Tcl. Currently being used
+in three drivers - for files, pipes and TCP-based sockets. (JL).
+
+11/7/95 (new feature) interp delete now takes any number of path
+names of interpreters to delete, including zero. (JL).
+
+11/8/95 (new feature) implemented 'info hostname' and Tcl_GetHostName
+command to get host name of machine on which the Tcl process is running. (JL)
+
+11/9/95 (new feature) Implemented file APIs for access to low level files
+on each system. The APIs are: Tcl_CloseFile, Tcl_OpenFile, Tcl_ReadFile,
+Tcl_WriteFile and Tcl_SeekFile. Also implemented Tcl_WaitPid which waits
+in a system dependent manner for a child process. (JL)
+
+11/9/95 (new feature) Added Tcl_UpdateLinkedVar procedure to force a
+Tcl variable to be updated after its C variable changes. (JO)
+
+11/9/95 (bug fix) The glob command has been totally reimplemented so
+that it can support different file name conventions.  It now handles
+Windows file names (both UNC and drive-relative) properly.  It also
+supports nested braces correctly now. (SS)
+
+11/13/95 (bug fix) Fixed Makefile.in so that configure can be run
+from a clean directory separate from the Tcl source tree, and compilations
+can be performed there. (JO)
+
+11/14/95 (bug fix) Fixed file sharing between interpreters and file
+transferring between interpreters to correctly manage the refcount so that
+files are closed when the last reference to them is discarded. (JL)
+
+11/14/95 (bug fix) Fixed gettimeofday implementation for the
+Macintosh.  This fixes several timing related bugs. (RJ)
+
+11/17/95 (new feature) Added missing support for info nameofexecutable
+on the Macintosh. (RJ)
+
+11/17/95 (bug fix) The Tcl variables argc argv and argv0 now return
+something reasonable on the Mac.  (RJ)
+
+11/22/95 (new feature) Implemented "auto-detect" mode for end of line
+translations. On input, standalone "\r" mean MAC mode, standalone "\n"
+mean Unix mode and "\r\n" means Windows mode. On output, the mode is
+modified to whatever the platform specific mode for that platform is. (JL)
+
+11/24/95 (feature change) Replaced "configInfo" file with tclConfig.sh,
+which is more complete and uses slightly different names.  Also
+arranged for tclConfig.sh to be installed in the platform-specific
+library directory instead of Tcl's script library directory. (JO)
+*** POTENTIAL INCOMPATIBILITY with Tcl 7.5a2, but not with Tcl 7.4 ***
+
+----------------- Released patch 7.4p3, 11/28/95 -----------------------
+
+12/5/95 (new feature) Added Tcl_File facility to support platform-
+independent file handles.  Changed all interfaces that used Unix-
+style integer fd's to use Tcl_File's instead. (SS)
+*** POTENTIAL INCOMPATIBILITY ***
+
+12/5/95 (new feature) Added a new "clock" command to Tcl.  The command
+allows you to get the current "clicks" or seconds & allows you to
+format or scan human readable time/date strings. (RJ)
+
+12/18/95 (new feature) Moved Tk_Preserve, Tk_Release, and Tk_EventuallyFree
+to Tcl, renamed to Tcl_Preserve, Tcl_Release, and Tcl_EventuallyFree. (JO)
+
+12/18/95 (new feature) Added new "package" command and associated
+procedures Tcl_PkgRequire and Tcl_PkgProvide.   Also wrote
+pkg_mkIndex library procedure to create index files from binaries
+and scripts. (JO)
+
+12/20/95 (new feature) Added Tcl_WaitForFile procedure. (JO)
+
+12/21/95 (new features) Made package name argument to "load" optional
+(Tcl will now attempt to guess the package name if necessary).  Also
+added Tcl_StaticPackage and support in "load" for statically linked
+packages.  (JO)
+
+12/22/95 (new feature) Upgraded the foreach command to accept multiple
+loop variables and multiple value lists.  This lets you iterate over
+multiple lists in parallel, and/or assign multiple loop variables from
+one value list during each iteration. The only potential compatibility
+problem is with scripts that used loop variables with a name that could be
+construed to be a list of variable names (i.e. contained spaces).  (BW)
+
+1/5/96 (new feature) Changed tclsh so it builds as a console mode
+application under Windows.  Now tclsh can be used from the command
+line with pipes or interactively.  Note that this only works under
+Windows 95 or NT. (SS)
+
+1/17/96 (new feature) Modified Makefile and configure script to allow
+Tcl to be compiled as a shared library:  use the --enable-shared option
+when configuing.  (JO)
+
+1/17/96 (removed obsolete features)  Removed the procedures Tcl_EnterFile
+and Tcl_GetOpenFile:  these no longer make sense with the new I/O system. (JL)
+*** POTENTIAL INCOMPATIBILITY ***
+
+1/19/96 (bug fixes) Prevented formation of circular aliases, through the
+Tcl 'interp alias' command and through the 'rename' command, as well as
+through the C API Tcl_CreateAlias. (JL)
+
+1/19/96 (bug fixes) Fixed several bugs in direct deletion of interpreters
+with Tcl_DeleteInterp when the interpreter is a slave; fixes based on a
+patch received from Viktor Dukhovni of ESM. (JL)
+
+1/19/96 (new feature) Implemented on-close handlers for channels; added
+the C APIs Tcl_CreateCloseHandler and Tcl_DeleteCloseHandler. (JL)
+
+1/19/96 (new feature) Implemented portable error reporting mechanism; added
+the C APIs Tcl_SetErrno and Tcl_GetErrno. (JL)
+
+1/24/96 (bug fix) Unknown command processing properly invokes external
+commands under Windows NT and Windows '95 now. (SS)
+
+1/23/96 (bug fix) Eliminated extremely long startup times under Windows '95.
+The problem was a result of the option database initialization code that
+concatenated $HOME with /.Xdefaults, resulting in a // in the middle of the
+file name.  Under Windows '95, this is incorrectly interpreted as a UNC
+path.  They delays came from the network timeouts needed to determine that
+the file name was invalid.  Tcl_TranslateFileName now suppresses duplicate
+slashes that aren't at the beginning of the file name. (SS)
+
+1/25/96 (bug fix) Changed exec and open to create children so they are
+attached to the application's console if it exists. (SS)
+
+1/31/96 (bug fix) Fixed command line parsing to handle embedded
+spaces under Windows. (SS)
+
+----------------- Released 7.5b1, 2/1/96 -----------------------
+
+2/7/96 (bug fix) Fixed off by one error in argument parsing code under
+Windows. (SS)
+
+2/7/96 (bug fix) Fixed bugs in VC++ makefile that improperly
+initialized the tcl75.dll.  Fixed bugs in Borland makefile that caused
+build failures under Windows NT. (SS)
+
+2/9/96 (bug fix) Fixed deadlock problem in AUTO end of line translation
+mode which would cause a socket server with several concurrent clients
+writing in CRLF mode to hang. (JL)
+
+2/9/96 (API change) Replaced -linemode option to fconfigure with a
+new -buffering option, added "none" setting to enable immediate write. (JL)
+*** INCOMPATIBILITY with b1 ***
+
+2/9/96 (new feature) Added C API Tcl_InputBuffered which returns the count
+of bytes currently buffered in the input buffer of a channel, and o for
+output only channels. (JL)
+
+2/9/96 (new feature) Implemented asynchronous connect for sockets. (JL)
+
+2/9/96 (new feature) Added C API Tcl_SetDefaultTranslation to set (per
+channel) the default end of line translation mode. This is the mode that
+will be installed if an output operation is done on the channel while it is
+still in AUTO mode. (JL)
+
+2/9/96 (bug fix) Changed Tcl_OpenCommandChannel interface to properly
+handle all of the combinations of stdio inheritance in background
+pipelines.  See the Tcl_OpenFileChannel(3) man page for more
+info.  This change fixes the bug where exec of a background pipeline
+was not getting passed the stdio handles properly. (SS)
+
+2/9/96 (bug fix) Removed the new Tcl_CreatePipeline interface, and
+restored the old version for Unix platforms only.  All new code should
+use Tcl_CreateCommandChannel instead. (SS)
+
+2/9/96 (bug fix) Changed Makefile.in to use -L and -ltcl7.5 for Tcl
+library so that shared libraries are more likely to be found correctly
+on more platforms. (JO)
+
+2/13/96 (new feature) Added C API Tcl_SetNotifierData and
+Tcl_GetNotifierData to allow notifier and channel driver writers to
+associate data with a Tcl_File.  The result of this change is that
+Tcl_GetFileInfo now always returns an OS file handle, and Tcl_GetFile
+can be used to construct a Tcl_File for an externally constructed OS
+handle. (SS)
+
+2/13/96 (bug fix) Changed Windows socket implementation so it doesn't
+set SO_REUSEADDR on server sockets.  Now attempts to create a server
+socket on a port that is already in use will be properly identified
+and an error will be generated. (SS)
+
+2/13/96 (bug fix) Fixed problems with DLL initialization under Visual
+C++ that left the C run time library uninitialized. (SS)
+
+2/13/96 (bug fix) Fixed Windows socket initialization so it loads
+winsock the first time it is used, rather than at the time tcl75.dll
+is loaded.  This should fix the bug where the modem immediately starts
+trying to connect to a service provider when wish or tclsh are
+started. (SS)
+
+2/13/96 (new feature) Added C APIs Tcl_MakeFileChannel and
+Tcl_MakeTcpClientChannel to wrap up existing fds and sockets into
+channels. Provided implementations on Unix and Windows. (JL)
+
+2/13/96 (bug fix) Fixed bug with seek leaving EOF and BLOCKING set. (JL)
+
+2/14/96 (bug fix) Fixed reentrancy problem in fileevent handling
+and made it more robust in the face of errors. (JL)
+
+2/14/96 (feature change) Made generic IO level emulate blocking mode if the
+channel driver is unable to provide it, e.g. if the low level device is
+always nonblocking. Thus, now blocking behavior is an advisory setting for
+channel drivers and can be ignored safely if the channel driver is unable
+to provide it. (JL)
+
+2/15/96 (new feature) Added "binary" end of line translation mode, which is
+a synonym of "lf" mode. (JL)
+
+2/15/96 (bug fix) Fixed reentrancy problem in fileevent handling vs
+deletion of channel event handlers. (JL)
+
+2/15/96 (bug fix) Fixed bug in event handling which would cause a
+nonblocking channel to not see further readable events after the first
+readable event that had insufficient input. (JL)
+
+2/17/96 (bug fix) "info complete" didn't properly handle comments
+in nested commands. (JO)
+
+2/21/96 (bug fix) "exec" under Windows NT/95 did not properly handle
+very long command lines (>200 chars). (SS)
+
+2/21/96 (bug fix) Sockets could get into an infinite loop if a read
+event arrived after all of the available data had been read. (SS)
+
+2/22/96 (bug fix) Added cast of st_size elements to (long) before
+sprintf-ing in "file size" command.  This is needed to handle systems
+like NetBSD with 64-bit file offsets.  (JO)
+
+----------------- Released 7.5b2, 2/23/96 -----------------------
+
+2/23/96 (bug fix) TCL_VARARGS macro in tcl.h wasn't defined properly
+when compiling with C++.  (JO)
+
+2/24/96 (bug fix) Removed dependencies on Makefile in the UNIX Makefile:
+this caused problems on some platforms (like Linux?). (JO)
+
+2/24/96 (bug fix) Fixed configuration bug that made Tcl not compile
+correctly on Linux machines with neither -ldl or -ldld. (JO)
+
+2/24/96 (new feature) Added a block of comments and definitions to
+Makefile.in to make it easier to have Tcl's TclSetEnv etc. replace
+the library procedures setenv etc, so that calls to setenv etc. in
+the application automatically update the Tcl "env" variable. (JO)
+
+2/27/96 (feature change) Added optional Tcl_Interp * argument (may be NULL)
+to C API Tcl_Close and simplified closing of command channels. (JL)
+*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
+
+2/27/96 (feature change) Added optional Tcl_Interp * argument (may be NULL)
+to C type definition Tcl_DriverCloseProc; modified all channel drivers to
+implement close procedures that accept the additional argument. (JL)
+*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
+
+2/28/96 (bug fix) Fixed memory leak that could occur if an upvar
+referred to an element of an array in the same stack frame as the
+upvar. (JO)
+
+2/29/96 (feature change) Modified both Tcl_DoOneEvent and Tcl_WaitForEvent
+so that they return immediately in cases where they would otherwise
+block forever (e.g. if there are no event handlers of any sort). (JO)
+
+2/29/96 (new feature) Added C APIs Tcl_GetChannelBufferSize and
+Tcl_SetChannelBufferSize to set and retrieve the size, in bytes, for
+buffers allocated to store input or output in a channel. (JL)
+
+2/29/96 (new feature) Added option -buffersize to Tcl fconfigure command
+to allow Tcl scripts to query and set the size of channel buffers. (JL)
+
+2/29/96 (feature removed) Removed channel driver function to specify
+the buffer size to use when allocating a buffer. Removed the C typedef
+for Tcl_DriverBufferSizeProc. Channels are now created with a default
+buffer size of 4K. (JL)
+*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
+
+2/29/96 (feature change) The channel driver function for setting blocking
+mode on the device may now be NULL. If the generic code detects that the
+function is NULL, operations that set the blocking mode on the channel
+simply succeed. (JL)
+
+3/2/96 (bug fix) Fixed core dump that could occur if a syntax error
+(such as missing close paren) occurred in an array reference with a
+very long array name. (JO)
+
+3/4/96 (bug fix) Removed code in the "auto_load" procedure that deletes
+all existing auto-load information whenever the "auto_path" variable
+is changed.  Instead, new information adds to what was already there.
+Otherwise, changing the "auto_path" variable causes all package-
+related information to be lost.  If you really want to get rid of
+existing auto-load information, use auto_reset before setting auto_path. (JO)
+
+3/5/96 (new feature) Added version suffix to shared library names so that
+Tcl will compile under NetBSD and FreeBSD (I hope).  (JO)
+
+3/6/96 (bug fix) Cleaned up error messages in new I/O system to correspond
+more closely to old I/O system. (JO)
+
+3/6/96 (new feature) Added -myaddr and -myport options to the socket
+command, removed -tcp and -- options.  This lets clients and servers
+choose a particular interface.  Also changed the default server address
+from the hostname to INADDR_ANY.  The server accept callback now gets
+passed the client's port as well as IP address.  The C interfaces for
+Tcl_OpenTcpClient and Tcl_OpenTcpServer have changed to support the
+above changes. (BW)
+*** POTENTIAL INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
+
+3/6/96 (changed feature) The library function auto_mkindex will now
+default to using the pattern "*.tcl" if no pattern is given. (RJ)
+
+3/6/96 (bug fix) The socket channel code for the Macintosh has been
+rewritten to use native MacTcp.  (RJ)
+
+3/7/96 (new feature) Added Tcl_SetStdChannel and Tcl_GetStdChannel
+interfaces to allow applications to explicitly set and get the global
+standard channels. (SS)
+
+3/7/96 (bug fix) Tcl did close not the file descriptors associated
+with "stdout", etc. when the corresponding channels were closed.  (SS)
+
+3/7/96 (bug fix) Reworked shared library and dynamic loading stuff to
+try to get it working under AIX.  Added new @SHLIB_LD_LIBS@ autoconf
+symbol as part of this.  AIX probably doesn't work yet, but it should
+be a lot closer. (JO)
+
+3/7/96 (feature change) Added Tcl_ChannelProc typedef and changed the
+signature of Tcl_CreateChannelHandler and Tcl_DeleteChannelHandler to take
+Tcl_ChannelProc arguments instead of Tcl_FileProc arguments. This change
+should not affect any code outside Tcl because the signatures of
+Tcl_ChannelProc and Tcl_FileProc are compatible. (JL)
+
+3/7/96 (API change) Modified signature of Tcl_GetChannelOption to return
+an int instead of char *, and to take a Tcl_DString * argument. Modified
+the implementation so that the option name can be NULL, to mean that the
+call should retrieve a list of alternating option names and values. (JL)
+*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
+
+3/7/96 (API change) Added Tcl_DriverSetOptionProc, Tcl_DriverGetOptionProc
+typedefs, added two slots setOptionProc and getOptionProc to the channel
+type structure. These may be NULL to indicate that the channel type does
+not support any options. (JL)
+*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
+
+3/7/96 (feature change) stdin, stdout and stderr can now be put into
+nonblocking mode. (JL)
+
+3/8/96 (feature change) Eliminated dependence on the registry for
+finding the Tcl library files. (SS)
+
+----------------- Released 7.5b3, 3/8/96 -----------------------
+
+3/12/96 (feature improvement) Modified startup script to look in several
+different places for the Tcl library directory.  This should allow Tcl
+to find the libraries under all but the weirdest conditions, even without
+the TCL_LIBRARY environment variable being set. (JO)
+
+3/13/96 (bug fix) Eliminated use of the "linger" option from the Windows
+socket implementation. (JL)
+
+3/13/96 (new feature) Added -peername and -sockname options for fconfigure
+for socket channels. Code contributed by John Haxby of HP. (JL)
+
+3/13/96 (bug fix) Fixed panic and core dump that would occur if the accept
+callback script on a server socket encountered an error. (JL)
+
+3/13/96 (feature change) Added -async option to the Tcl socket command.
+If the command is creating a client socket and the flag is present, the
+client is connected asynchronously. If the option is absent (the default),
+the client socket is connected synchronously, and the command returns only
+when the connection has been completed or failed. This change was suggested
+by Mark Diekhans. (JL)
+
+3/13/96 (feature change) Modified the signature of Tcl_OpenTcpClient to
+take an additional int argument, async. If nonzero, the client is connected
+to the server asynchronously. If the value is zero, the connection is made
+synchronously, and the call to Tcl_OpenTcpClient returns only when the
+connection fails or succeeds. This change was suggested by Mark Diekhans. (JL)
+*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
+
+3/14/96 (bug fix) "tclsh bogus_file_name" didn't print an error message. (JO)
+
+3/14/96 (bug fix) Added new procedures to tclCkalloc.c so that libraries
+and applications can be compiled with TCL_MEM_DEBUG even if Tcl isn't
+(however, the converse is still not true).  Patches provided by Jan
+Nijtmans. (JO)
+
+3/15/96 (bug fix) Marked standard IO handles of a process as close-on-exec
+to fix bug in Ultrix where exec was not sharing standard IO handles with
+subprocesses. Fix suggested by Mark Diekhans. (JL)
+
+3/15/96 (bug fix) Fixed asynchronous close mechanism so that it closes the
+channel instead of leaking system resources. The manifestation was that Tcl
+would eventually run out of file descriptors if it was handling a large
+number of nonblocking sockets or pipes with high congestion. (JL)
+
+3/15/96 (bug fix) Fixed tests so that they no longer leak file descriptors.
+The manifestation was that Tcl would eventually run out of file descriptors
+if the tests were rerun many times (> a hundred times on Solaris). (JL)
+
+3/15/96 (bug fix) Fixed channel creation code so that it never creates
+unnamed channels. This would cause a panic and core dump when the channel
+was closed. (JL)
+
+3/16/96 (bug fixes) Made lots of changes in configuration stuff to get
+Tcl working under AIX (finally).  Tcl should now support the "load"
+command under AIX and should work either with or without shared
+libraries for Tcl and Tk. (JO)
+
+3/21/96 (configuration improvement) Changed configure script so it
+doesn't use version numbers (as in -ltcl7.5 and libtcl7.5.so) under
+SunOS 4.1, where they don't work anyway.  (JO)
+
+3/22/96 (new feature) Added C API Tcl_InterpDeleted that allows extension
+writers to discover when an interpreter is being deleted. (JL)
+
+3/22/96 (bug fix) The standard IO channels are now added to each
+trusted interpreter as soon as the interpreter is created. This ensures
+against the bug where a child would do IO before the master had done any,
+and then the child is destroyed - the standard IO channels would be then
+closed and the master would be unable to do any IO. (JL)
+
+3/22/96 (bug fix) Made Tcl more robust against interpreter deletion, by
+using Tcl_Preserve, Tcl_Release and Tcl_EventuallyFree to split the process
+of interpreter deletion into two distinct phases. Also went through all of
+Tcl and added calls to Tcl_Preserve and Tcl_Delete where needed. (JL)
+
+3/22/96 (bug fix) Fixed several places where C code was reading and writing
+into freed memory, especially during interpreter deletion. (JL)
+
+3/22/96 (bug fix) Fixed very deep bug in Tcl_Release that caused memory to
+be freed twice if the release callback did Tcl_Preserve and Tcl_Release on
+the same memory as the chunk currently being freed. (JL)
+
+3/22/96 (bug fix) Removed several memory leaks that would cause memory
+buildup on half-K chunks in the generic IO level. (JL)
+
+3/22/96 (bug fix) Fixed several core dumps which occurred when new
+AssocData was being created during the cleanups in interpreter deletion.
+The solution implemented now is to loop repeatedly over the AssocData until
+none is left to clean up. (JL)
+
+3/22/96 (bug fix) Fixed a bug in event handling which caused an infinite
+loop if there were no files being watched and no timer. Fix suggested by
+Jan Nijtmans. (JL)
+
+3/22/96 (bug fix) Fixed Tcl_CreateCommand, Tcl_DeleteCommand to be more
+robust if the interpreter is being deleted. Also fixed several order
+dependency bugs in Tcl_DeleteCommand which kicked in when an interpreter
+was being deleted. (JL)
+
+3/26/96 (bug fix) Upon a "short read", the generic code no longer calls
+the driver for more input. Doing this caused blocking on some platforms
+even on nonblocking channels. Bug and fix courtesy Mark Roseman. (JL)
+
+3/26/96 (new feature) Added 'package Tcltest' which is present only in
+test versions of Tcl; this allows the testing commands to be loaded into
+new interpreters besides the main one. (JL)
+
+3/26/96 (restored feature) Recreated the Tcl_GetOpenFile C API. You can
+now get a FILE * from a registered channel; Unix only. (JL)
+
+3/27/96 (bug fix) The regular expression code did not support more
+than 9 subexpressions.  It now supports up to 20. (SS)
+
+4/1/96 (bug fixes) The CHANNEL_BLOCKED bit was being left on on a short
+read, so that fileevents wouldn't fire correctly. Bug reported by Mark
+Roseman.(JL, RJ)
+
+4/1/96 (bug fix) Moved Tcl_Release to match Tcl_Preserve exactly, in
+tclInterp.c; previously interpreters were being freed only conditionally
+and sometimes not at all. (JL)
+
+4/1/96 (bug fix) Fixed error reporting in slave interpreters when the
+error message was being generated directly by C code. Fix suggested by
+Viktor Dukhovni of ESM. (JL)
+
+4/2/96 (bug fixes) Fixed a series of bugs in Windows sockets that caused
+events to variously get lost, to get sent multiple times, or to be ignored
+by the driver. The manifestation was blocking if the channel is blocking,
+and either getting EAGAIN or infinite loops if the channel is nonblocking.
+This series of bugs was found by Ian Wallis of Cisco. Now all tests (also
+those that were previously commented out) in socket.test pass.  (JL, SS)
+
+4/2/96 (feature change/bug fix) Eliminated network name support in
+favor of better native name support.  Added "file split", "file join",
+and "file pathtype" commands.  See the "file" man page for more
+details. (SS)
+*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
+
+4/2/96 (bug fix) Changed implementation of auto_mkindex so tclIndex
+files will properly handle path names in a cross platform context. (SS)
+
+4/5/96 (bug fix) Fixed Tcl_ReadCmd to use the channel buffer size as the
+chunk size it reads, instead of a fixed 4K size. Thus, on large reads, the
+user can set the channel buffer size to a large size and the read will
+occur orders of magnitude faster. For example, on a 2MB file, reading in 4K
+chunks took 34 seconds, while reading in 1MB chunks took 1.5 seconds (on a
+SS-20). Problem identified and fix suggested by John Haxby of HP. (JL)
+
+4/5/96 (bug fix) Fixed socket creation code to invoke gethostbyname only if
+inet_addr failed (very unlikely). Before this change the order was reversed
+and this made things much slower than they needed to be (gethostbyname
+generally requires an RPC, which is slow). Problem identified and fix
+suggested by John Loverso of OSF. (JL)
+
+4/9/96 (feature change) Modified "auto" translation mode so that it
+recognizes any of "\n", "\r" and "\r\n" in input as end of line, so
+that a file can have mixed end-of-line sequences. It now outputs
+the platform specific end of line sequence on each platform for files and
+pipes, and for sockets it produces crlf in output on all platforms. (JL)
+*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
+
+4/11/96 (new feature) Added -eofchar option to Tcl_SetChannelOption to allow
+setting of an end of file character for input and output. If an input eof
+char is set, it is recognized as EOF and further input from the channel is
+not presented to the caller. If an output eof char is set, on output, that
+byte is appended to the channel when it is closed. On Unix and Macintosh,
+all channels start with no eof char set for input or output. On Windows,
+files and pipes start with input and output eof chars set to Crlt-Z (ascii
+26), and sockets start with no input or output eof char. (JL)
+*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
+
+4/17/96 (bug fix) Fixed series of bugs with handling of crlf sequence split
+across buffer boundaries in input, in AUTO mode. (JL, BW)
+
+4/17/96 (test suite improvement) Fixed test suite so that tests that
+depend on the availability of Unix commands such as echo, cat and others
+are not run if these commands are not present. (JL)
+
+4/17/96 (test suite improvement) The socket test now automatically starts,
+on platformst that support exec, a separate process for remote testsing. (JL)
+
+----------------- Released 7.5, 4/21/96 -----------------------
+
+5/1/96 (bug fix) "file tail ~" did not correctly return the tail
+portion of the user's home directory. (SS)
+
+5/1/96 (bug fix) Fixed bug in TclGetEnv where it didn't lookup environment
+variables correctly:  could confuse "H" and "HOME", for example.  (JO)
+
+5/1/96 (bug fix) Changed to install tclConfig.sh under "make install-binaries",
+not "make install-libraries".  (JO)
+
+5/2/96 (bug fix) Changed pkg_mkIndex not to attempt to "load" a file unless
+it has the standard shared library extension.  On SunOS, attempts to load
+Tcl scripts cause the whole application to be aborted (there's no way to
+get the error back into Tcl).  (JO)
+
+5/7/96 (bug fix) Moved initScript in tclUnixInit.c to writable memory to
+avoid potential core dumps. (JO)
+
+5/7/96 (bug fix) Auto_reset procedure was removing procedure from init.tcl,
+such as pkg_mkIndex.  (JO)
+
+5/7/96 (bug fix) Fixed cast on socket address resolution code that
+would cause a failure to connect on Dec Alphas. (JL)
+
+5/7/96 (bug fix) Added "time", "subst" and "fileevent" commands to set of
+commands available in a safe interpreter. (JL)
+
+5/13/96 (bug fix) Preventing OS level handles for stdin, stdout and stderr
+from being implicitly closed when the last reference to the standard
+channel containing that handle is discarded when an interpreter is deleted.
+Explicitly closing standard channels by using "close" still works. (JL)
+
+5/21/96 (bug fix) Do not create channels for stdin, stdout and stderr on
+Unix if the devices are closed. This prevents a duplicate channel name
+panic later on when the fd is used to open a channel and the channel is
+registered in an interpreter. (JL)
+
+5/23/96 (bug fix) Fixed bug that prevented the use of standard channels in
+interpreters created after the last interpreter was destroyed. In the sequence
+
+	interp = Tcl_CreateInterp();
+	Tcl_DeleteInterp(interp);
+	interp = Tcl_CreateInterp();
+
+channels for stdio would not be available in the second interpreter. (JL)
+
+5/23/96 (bug fix) Fixed bug that allowed Tcl_MakeFileChannel to create new
+channels with Tcl_Files in them that are already used by another channel.
+This would cause core dumps when the Tcl_Files were being freed twice. (JL)
+
+5/23/96 (bug fix) Fixed a logical timing bug that caused a standard channel
+to be removed from the standard channel table too early when the channel
+was being closed. If the channel was being flushed asynchronously, it could
+get recreated before being actually destroyed, and the recreated channel
+would contain the same Tcl_File as the one being closed, leading to
+dangling pointers and core dumps. (JL)
+
+5/27/96 (bug fix) Fixed a bug in Tcl_GetChannelOption which caused it to
+always return a list of one element, a list of the settings, for
+-translation and -eofchar options. Now correctly returns the value
+described by the documentation (Mark Diekhans found this, thanks!). (JL)
+
+5/30/96 (bug fix) Fixed a couple of syntax errors in io.test. (JL)
+
+5/30/96 (bug fix) If a fileevent scripts gets an error, delete it before
+causing a background error. This is to allow the error handler to reinstall
+the fileevent and to prevent infinite loops if the event loop is reentered
+in the error handler. (JL)
+
+5/31/96 (bug fix) Channels now will get properly flushed on exit. (JL)
+
+6/5/96 (bug fix) Changed Tcl_Ckalloc, Tcl_Ckfree, and Tcl_Ckrealloc to
+Tcl_Alloc, Tcl_Free, and Tcl_Realloc.  Added documentation for these
+routines now that they are officially supported.  Extension writers
+should use these routines instead of free() and malloc(). (SS)
+
+6/10/96 (bug fix) Changes the Tcl close command so that it no longer
+waits on nonblocking pipes for the piped processes to exit; instead it
+reaps them in the background. (JL)
+
+6/11/96 (bug fix) Increased the length of the listen queue for server
+sockets on Unix from 5 to 100. Some OSes will disregard this and reset it
+to 5, but we should try to get as long a queue as we can, for performance
+reasons. (JL)
+
+6/11/96 (bug fix) Fixed windows sockets bug that caused a cascade of events
+if the fileevent script read less than was available. Now reading less than
+is available does not cause a flood of Tcl events. (JL, SS)
+
+6/11/96 (bug fix) Fixed bug in background flushing on closed channels that
+would prevent the last buffer from getting flushed. (JL)
+
+6/13/96 (bug fix) Fixed bug in Windows sockets that caused a core dump if
+a DLL linked with tcl.dll and referred to e.g. ntohs() without opening a
+Tcl socket. The problem was that the indirection table was not being
+initialized. (JL)
+
+6/13/96 (bug fix) Fixed OS level resource leak that would occur when a
+Tcl channel was still registered in some interpreter when the process
+exits. Previously the channel was not being closed and the OS level handles
+were not being released; the output was being flushed but the device was
+not being closed. Now the device is properly closed. This was only a
+problem on Win3.1 and MacOS. (JL, SS)
+
+6/28/96 (bug fix) Fixed bug where transient errors were leaving an error
+code around, so that it would erroneously get reported later. This bug was
+exercised intermittently by closing a channel to a file on a very loaded
+NFS server, or to a socket whose other end blocked. (JL, BW)
+
+7/3/96 (bug fix) Fileevents declared in an interpreter are now deleted
+when the channel is closed in that interpreter. Before this fix, the
+fileevent would hang around until the channel is completely closed, and
+would cause errors if events happened before the channel was closed. This
+could happen in two cases: first if the channel is shared between several
+interpreters, and second if an async flush is in progress that prevents the
+channel from being closed until the flush finishes. (JL)
+
+7/10/96 (bug fix) Fixed bugs in both "lrange" and "lreplace" commands
+where too much white space was being removed. For example, the command
+		lreplace {\}\     hello} end end
+was returning "\}\", losing the significant space in the first list
+element and corrupting the list. (JO)
+
+7/20/96 (bug fix) The procedure pkg_mkIndex didn't work properly for
+extensions that depend on Tk, because it didn't load Tk into the child
+interpreter before loading the extension.  Now it loads Tk if Tk is
+present in the parent. (JO)
+
+7/23/96 (bug fix) Added compat version of strftime to fix crashes
+resulting from bad implementations under Windows. (SS)
+
+7/23/96 (bug fix) Standard implementations of gmtime() and localtime()
+under Windows did not handle dates before 1970, so they were replaced
+with a revised implementation. (SS)
+
+7/23/96 (bug fix) Tcl would crash on exit under Borland 5.0 because
+the global environ pointer was left pointing to freed memory. (SS)
+
+7/29/96 (bug fix) Fixed memory leak in Tcl_LoadCmd that could occur if
+a package's AppInit procedure called Tcl_StaticPackage to register
+static packages. (JO)
+
+8/1/96 (bug fix) Fixed a series of bugs in Windows sockets so that async
+writebehind in the presence of read event handlers now works, and so that
+async writebehind also works on sockets for which a read event handler was
+declared and whose channels were then closed before the async write
+finished. The bug was reported by John Loverso and Steven Wahl,
+independently, test case supplied by John Loverso. (JL)
+
+----------------- Released patch 7.5p1, 8/2/96 -----------------------
+
+5/8/96 (new feature) Added Tcl_GetChannelMode C API for retrieving whether
+a channel is open for reading and writing. (JL)
+
+5/8/96 (API changes) Revised C APIs for channel drivers:
+    - Removed all Tcl_Files from channel driver interface; you can now have
+      channels that are not based on Tcl_Files.
+    - Added channelReadyProc and watchChannelProc procedures to interface;
+      these are used to implement event notification for channels.
+    - Added getFileProc to channel driver, to allow the generic IO code
+      to retrieve a Tcl_File from a channel (presumably if the channel
+      uses Tcl_Files they will be stored inside its instanceData). (JL)
+*** INCOMPATIBILITY with Tcl 7.5 ***
+
+5/8/96 (API change) The Tcl_CreateChannel C API was modified to not take
+Tcl_File arguments, and instead to take a mask specifying whether the
+channel is readable and/or writable. (JL)
+*** INCOMPATIBILITY with Tcl 7.5 ***
+
+6/3/96 (bug fix) Made Tcl_SetVar2 robust against the case where the value
+of the variable is a NULL pointer instead of "". (JL)
+
+6/17/96 (bug fix) Fixed "reading uninitialized memory" error reported by
+Purify, in Tcl_Preserve/Tcl_Release. (JL)
+
+8/9/96 (bug fix) Fixed bug in init.tcl that caused incorrect error message
+if the act of autoloading a procedure caused the procedure to be invoked
+again. (JO)
+
+8/9/96 (bug fix) Configure script produced bad library names and extensions
+under SunOS and a few other platforms if the --disable-load switch was used.
+(JO)
+
+8/9/96 (bug fix) Tcl_UpdateLinkedVar generated an error if the variable
+being updated was read-only. (JO)
+
+8/14/96 (bug fix) The macintosh now supports synchronous socket
+connections.  Other minor bugs were also fixed. (RJ)
+
+8/15/96 (configuration improvement) Changed the file patchlevel.h
+to be tclPatch.h.  This avoids conflict with the Tk file and is now
+in 8.3 format on the Windows platform. (RJ)
+
+8/20/96 (bug fix) Fixed core dump in interp alias command for interpreters
+created with Tcl_CreateInterp (as opposed to with Tcl_CreateSlave). (JL)
+
+8/20/96 (bug fix) No longer masking ECONNRESET on Windows sockets so
+that the higher level of the IO mechanism sees the error instead of
+entering an infinite loop. (JL)
+
+8/20/96 (bug fix) Destroying the last interpreter no longer closes the
+standard channels. (JL)
+
+8/20/96 (bug fix) Closing one of the stdin, stdout or stderr channels and
+then opening a new channel now correctly assigns the new channel as the
+standard channel that was closed. (JL)
+
+8/20/96 (bug fix) Added code to unix/tclUnixChan.c for using ioctl with
+FIONBIO instead of fcntl with O_NONBLOCK, for those versions of Unix where
+either O_NONBLOCK is not supported or implemented incorrectly. (JL)
+
+8/21/96 (bug fix) Fixed "file extension" so it correctly returns the
+extension on files like "foo..c" as "..c" instead of ".c". (SS)
+
+8/22/96 (bug fix) If environ[] contains static strings, Tcl would core
+dump in TclSetupEnv because it was trying to write NULLs into the actual
+data in environ[]. Now we instead copy as appropriate. (JL)
+
+8/22/96 (added impl) Added missing implementation of Tcl_MakeTcpClientChannel
+for Windows platform. Code contributed by Mark Diekhans. (JL)
+
+8/22/96 (new feature) Added a new memory allocator for the Macintosh
+version of Tcl.  It's quite a bit faster than MetroWerk's version. (RJ)
+
+8/26/96 (documentation update) Removed old change bars (for all changes
+in Tcl 7.5 and earlier releases) from manual entries. (JO)
+
+8/27/96 (enhancement) The exec and open commands behave better and work in
+more situations under Windows NT and Windows 95.  Documentation describes
+what is still lacking. (CS)
+
+8/27/96 (enhancement) The Windows makefiles will now compile even if the
+compiler is not in the path and/or the compiler's environment variables
+have not been set up. (CS)
+
+8/27/96 (configuration improvement) The Windows resource files are
+automatically updated when the version/patch level changes.  The header file
+now has a comment that reminds the user which other files must be manually
+updated when the version/patch level changes. (CS)
+
+8/28/96 (new feature) Added file manipulation features (copy, rename, delete,
+mkdir) that are supported on all platforms. They are implemented as
+subcommands to the "file" command. See the documentation for the "file"
+command for more information. (JH)
+
+----------------- Released 7.6b1, 8/30/96 -----------------------
+
+9/3/96 (bug fix) Simplified code so that standard channels are created
+lazily, they are added to an interpreter lazily, and they are never added
+to a safe interpreter. (JL)
+
+9/3/96 (bug fix) Closing a channel after closing a standard channel, e.g.
+stdout, would cause the implicit recreation of that standard channel. (JL)
+
+9/3/96 (new feature) Now calling Tcl_RegisterChannel with a NULL
+interpreter increments the refcount so that code outside any interpreter
+can use channels that are also registered in interpreters, without worrying
+that the channel may turn into a dangling pointer at any time. Calling
+Tcl_UnregisterChannel with a NULL interpreter only decrements the recount
+so that code outside any interpreter can safely declare it is no longer
+interested in a channel. (JL)
+
+9/4/96 (new features) Two changes to dynamic loading:
+    - If the file name is empty in the "load" command and there is no
+      statically loaded version of the package, a dynamically loaded
+      version will be used if there is one.
+    - Tcl_StaticPackage ignores redundant calls for the same package. (JO)
+
+9/6/96 (bug fix) Platform specific procedures for manipulating files are
+no longer macros and have been prefixed with "Tclp", such as TclpRenameFile.
+Unix file code now handles symbolic links and other special files correctly.
+The semantics of file copy and file rename has been changed so that if
+a target directory exists, the source files will NOT be merged with the
+existing files. (JH)
+
+9/6/96 (bug fix) If standard channel is NULL, because Tcl cannot connect
+to the standard channel, do not increment the refcount. The channel can
+be NULL if there is for example no standard input. (JL)
+
+9/6/96 (portability improvement) Changed parsing of backslash sequences
+like \n to translate directly to absolute values like 0xa instead of
+letting the compiler do the translation.  This guarantees that the
+translation is done the same everywhere. (JO)
+
+9/9/96 (bug fix) If channel is opened and not associated with any
+interpreter, but Tcl decides to use it as one of the standard channels, it
+became impossible to close the channel with Tcl_Close -- instead you had
+to call Tcl_UnregisterChannel. Fixed now so that it's safe to call
+Tcl_Close even when Tcl is using the channel as one of the standard ones. (JL)
+
+9/11/96 (feature change) The Tcl library is now placed in the Tcl
+shared libraries resource.  You no longer need to place the Tcl files
+in your applications explicitly.  (RJ)
+
+9/11/96 (feature change) Extensions no longer automatically have the
+resource fork of the extension opened for it.  Instead you need to
+use the tclMacLibrary.c file in your extension.  (RJ)
+*** POTENTIAL INCOMPATIBILITY ***
+
+9/12/96 (bug fix) The extension loading mechanism on the Macintosh now
+looks at the 'cfrg' resource to determine where to load the code
+fragment from.  This means FAT fragments should now work. (RJ)
+
+9/18/96 (enhancement) The exec and open commands behave better and work in
+more situations under Windows 3.X.  Documentation describes what is still
+lacking.  (CS)
+
+9/19/96 (bug fix) Fixed a panic which would occur if you delete a
+non-existent alias before any aliases are created. Now instead correctly
+returns an error that the alias is not found. (JL)
+
+9/19/96 (bug fix) Slave interpreters could rename aliases and they would
+not get deleted when the alias was being redefined. This led to dangling
+pointers etc. (JL)
+
+9/19/96 (bug fix) Fixed a panic where a hash table entry was being deleted
+twice during alias management operations. (JL)
+
+9/19/96 (bug fix) Fixed bug in event loop that could cause the input focus
+in Tk to get confused during menu traversal, among other problems.  The
+problem was related to handling of the "marker" when its event was
+deleted. (JO)
+
+9/26/96 (bug fix) Windows was losing EOF on a socket if the FD_CLOSE event
+happened to precede any left over FD_READ events. Now correctly remembers
+seeing FD_CLOSE, so that trailing FD_READ events are not discarded if they
+do not contain any data. This allows Tcl to correctly get a zero read and
+notice EOF. (JL)
+
+9/26/96 (bug fix) Was not resetting READABLE state properly on sockets
+under Windows if the driver discarded an FD_READ event because no data was
+present. Now correctly resets the state. (JL)
+
+9/30/96 (bug fix) Made EOF sticky on Windows sockets, so that fileevent
+readable will fire repeatedly until the socket is closed. Previously the
+fileevent fired only once. This could lead to never-closed connections if
+the Tcl script in the fileevent wasn't closing the socket immediately. (JL)
+
+10/2/96 (new feature) Improved the package loader:
+    - Added new variable tcl_pkgPath, which holds the default
+      directories under which packages are normally installed (each
+      package goes in a separate subdirectory of a directory in
+      $tcl_pkgPath).  These directories are included in auto_path by
+      default.
+    - Changed the package auto-loader to look for pkgIndex.tcl files
+      not only in the auto_path directories but also in their immediate
+      children.  This should make it easier to install and uninstall
+      packages (don't have to change auto_path or merge pkgIndex.tcl
+      files). (JO)
+
+10/3/96 (bug fix) Changed tclsh to look for tclshrc.tcl instead of
+tclsh.rc on startup under Windows.  This is more consistent with wish and
+uses the right extension. (SS)
+*** POTENTIAL INCOMPATIBILITY ***
+
+10/8/96 (bug fix) Convertclock does not parse 24-hour times of the
+form "hhmm" correctly when hour = 00.  In the parse code, hour must be
+>= 100 for minutes to be non-zero.  Thanks to Lint LaCour for this
+bug fix. (RJ)
+
+10/11/96 (bug fix) Under Windows, the pid command returned the process
+handle instead of the process id. (SS)
+
+----------------- Released 7.6, 10/16/96 -----------------------
+
+10/29/96 (bug fix) Under Windows, sockets would consume 100% CPU time after
+the first accept(), due to a typo. (JL)
+
+10/29/96 (bug fix) Incorrect refcount management caused standard channels
+not to get deleted at process exit or DLL unload time, causing a memory
+leak of upwards of 20K each time. (JL)
+
+11/7/96 (bug fix) Auto-exec didn't work on file names that contained
+spaces. (JO)
+
+11/8/96 (bug fix) Fixed core dump that would occur if more than one call
+to Tcl_DeleteChannelHandler was made to delete a given channel handler. (JL)
+
+11/8/96 (bug fix) Fixed test for return value in Tcl_Seek and Tcl_SeekCmd
+to only treat -1 as error, instead of all negative numbers. (JL)
+
+11/12/96 (bug fix) Do not blocking waiting for processes at the end of a
+pipe during exit cleanup. (JL)
+
+11/12/96 (bug fix) If we are in exit cleanup, do not close the system level
+file descriptors 0, 1 and 2. Previously they were being closed which is
+incorrect, in the embedded case. This led to weird behavior for programs
+that want to interpose on I/O through the standard file descriptors (e.g.
+Netscape Navigator). (JL)
+
+11/15/96 (bug fix) Fixed core dump on Windows sockets due to dependency on
+deletion order at exit. Now all socket functions check to see if sockets
+are (still) initialized, before calling through function pointers. Before,
+they would call and might end up calling unloaded object code. (JL)
+
+11/15/96 (bug fix) Fixed core dump in Windows socket initialization routine
+if sockets were not installed on the system. Before, it was not properly
+checking the result of attempting to load the socket DLL, so it would call
+through uninitialized function pointers. (JL)
+
+11/15/96 (bug fix) Fixed memory leak in Windows sockets which left socket
+DLL handle open and could hold the socket DLL in memory uneccessarily,
+until a reboot. (JL)
+
+12/4/96 (bug fix) Fixed bug in Macintosh socket code that could result
+in lost data if a client was closed too soon after sending data. (RJ)
+
+12/17/96 (bug fix) Fixed deadlock bug in Windows sockets due to losing an
+event. This was happening because of an interaction between buffering and
+nonblocking mode on sockets. Now switched to sockets being blocking by
+default, so we are also no longer emulating blocking through a private
+event loop. (JL)
+
+1/21/97 (performance bug fix) Client TCP connections were slow to create
+because getservbyname was always called on the port.  Now this is only
+done if Tcl_GetInt fails. (BW)
+
+1/21/97 (configuration fix) Made it possible to override TCL_PACKAGE_PATH
+during make.  Previously it was only set during autoconf process.
+
+1/29/97 (bug fix) Fixed some problems with the clock command that
+impacted how dates were scaned after the year 2000. (RJ)
+
+----------------- Released 7.6p2, 1/31/97 -----------------------
+
+2/5/97 (bug fix) Fixed a bug where in CR-LF translation mode, \r bytes
+in the input stream were not being handled correctly. (JL)
+
+2/24/97 (bug fix) Fix bug with exec under Win32s not being able to create
+stderr file which caused all execs to fail.  Fixed temp file leak under
+Win32s.  Fixed optional parameter bug with SearchPath that only happened
+under Win32s 1.25. (CCS)
+
+----------------------------------------------------------
+Changes for Tcl 7.6 go above this line.
+Changes for Tcl 7.7 go below this line.
+----------------------------------------------------------
+
+5/8/96 (new feature) Added Tcl_Ungets C API for putting a sequence of bytes
+into a channel's input buffer. This can be used for "push" model channels
+where the input is obtained via callbacks instead of by request of the
+generic IO code. No Tcl procedure yet. (JL)
+
+11/15/96 (new feature) Implemented hidden commands. New C APIs:
+	Tcl_HideCommand		-- hides an existing exposed command.
+	Tcl_ExposeCommand	-- exposes an existing hidden command.
+New tcl APIs:
+	interp invokehidden	-- invokes a hidden command in a slave.
+	interp hide		-- hides an existing exposed command.
+	interp expose		-- exposes an existing hidden command.
+	interp hidden		-- returns a list of hidden commands.
+The implementation of Safe Tcl now uses the new hidden commands facility
+to implement the safe base, instead of deleting the commands from a safe
+interpreter. (JL)
+
+11/15/96 (new feature) Implemented the safe base, a mechanism for
+installing and requesting security policies, purely in Tcl code. Overloads
+the package command to also allow an interpreter to "require" a policy. The
+following new library commands are provided:
+	tcl_safeCreateInterp	-- creates a slave an initializes the
+				   policy mechanism.
+	tcl_safeInitInterp	-- initializes an existing slave with the
+				   policy mechanism.
+	tcl_safeDeleteInterp	-- deletes a slave and deinitializes the
+				   policy mechanism.
+Added a new file to the library, safeinit.tcl, to hold implementation. (JL)
+On 7/9/97, removed the policy loading mechanism from the Safe Base. Left
+only the Safe Base aliases dealing with auto-loading and source. (JL)
+
+12/6/96 (new feature) Implemented Tcl_Finalize, an API that should be
+called by a process when it is done using Tcl. This API runs all the exit
+handlers to allow them to clean up resources etc. (JL)
+
+12/17/96 (new feature) Add an http Tcl script package to the Tcl library.
+This package implements the client side of HTTP/1.0; the GET, HEAD,
+and POST requests. (BW)
+
+1/21/97 (new feature) Added a "marktrusted" subcommand to the "interp" and
+to the interpreter object command. It removes the "safe" mark on an
+interpreter and disables hard-wired checks for safety in the C sources. (JL)
+
+1/21/97 (removed feature) Removed "vwait" from set of commands available in
+a safe interpreter. (JL)
+
+2/11/97 (new feature, bug fix) http package.  Added -accept to http_config
+so you can set the Accept header.  Added -handler option to http_get so
+you can supply your own data handler.  Also fixed POST operation to
+set the correct MIME type on the request. (BW)
+
+----------------------------------------------------------
+Changes for Tcl 7.7 go above this line.
+Changes for Tcl 8.0 go below this line.
+----------------------------------------------------------
+
+9/17/96 (bug fix) Using "upvar" it was possible to turn an array element
+into an array itself.  Changed to disallow this; it was quirky and didn't
+really work correctly anyway. (JO)
+
+10/21/96 (new feature) The core of the Tcl interpreter has been replaced
+with an on-the-fly compiler that translates Tcl scripts to bytecoded
+instructions; a new interpreter then executes the bytecodes. The compiler
+introduces only a few minor changes at the level of Tcl scripts. The biggest
+changes are to expressions and lists.
+    - A second level of substitutions is no longer done for expressions.
+      This substantially improves their execution time. This means that
+      the expression "$x*4" produces a different result than in the past
+      if x is "$y+2". Fortunately, not much code depends on the old
+      two-level semantics. Some expressions that do, such as
+      "expr [join $list +]" can be recoded to work in Tcl8.0 by adding
+      an eval: e.g., "eval expr [join $list +]".
+    - Lists are now completely parsed on the first list operation to
+      create a faster internal representation. In the past, if you had a
+      misformed list but the erroneous part was after the point you
+      inserted or extracted an element, then you never saw an error.
+      In Tcl8.0 an error will be reported. This should only effect
+      incorrect programs that took advantage of behavior of the old
+      implementation that was not documented in the man pages.
+Other changes to Tcl scripts are discussed in the web page at
+http://www.scriptics.com/doc/compiler.html. (BL)
+*** POTENTIAL INCOMPATIBILITY ***
+
+10/21/96 (new feature) In earlier versions of Tcl, strings were used as a
+universal representation; in Tcl 8.0 strings are replaced with Tcl_Obj
+structures ("objects") that can hold both a string value and an internal
+form such as a binary integer or compiled bytecodes. The new objects make it
+possible to store information in efficient internal forms and avoid the
+constant translations to and from strings that occurred with the old
+interpreter. There are new many new C APIs for managing objects. Some of the
+new library procedures for objects (such as Tcl_EvalObj) resemble existing
+string-based procedures (such as Tcl_Eval) but take advantage of the
+internal form stored in Tcl objects for greater speed. Other new procedures
+manage objects and allow extension writers to define new kinds of objects.
+See the manual entries doc/*Obj*.3 (BL)
+
+10/24/96 (bug fix) Fixed memory leak on exit caused by some IO related
+data structures not being deallocated on exit because their refcount was
+artificially boosted. (JL)
+
+10/24/96 (bug fix) Fixed core dump in Tcl_Close if called with NULL
+Tcl_Channel. (JL)
+
+11/19/96 (new feature) Added library procedures for finding word
+breaks in strings in a platform specific manner.  See the library.n
+manual entry for more information. (SS)
+
+11/22/96 (feature improvements) Added support for different levels of
+tracing during bytecode compilation and execution. This should help in
+tracking down suspected problems with the compiler or with converting
+existing code to use Tcl8.0. Two global Tcl variables, traceCompile
+and traceExec, can be set to generate tracing information in stdout:
+    - traceCompile: 0  no tracing (default)
+                    1  trace compilations of top level commands and procs
+                    2  trace and display instructions for all compilations
+    - traceExec:    0  no tracing
+                    1  trace only calls to Tcl procs
+                    2  trace invocations of all commands including procs
+                    3  detailed trace showing the result of each instruction
+traceExec >= 2 provides a one line summary of each called command and
+its arguments. Commands that have been "compiled away" such as set are
+not shown. (BL)
+
+11/30/96 (bug fix) The command "info nameofexecutable" could sometimes
+return the name of a directory. (JO)
+
+11/30/96 (feature improvements) Changed the code in library/init.tcl
+that reads in pkgIndex.tcl so that (a) it reads the files from child
+directories before those in the parent, so that the parent gets
+precedence, and (b) it doesn't quit if there is an error in a
+pkgIndex.tcl file;  instead, it prints an error message on standard
+error and continues. (JO)
+
+10/5/96 (feature improvements) Partial implementation of binary string
+support: the ability for Tcl string values to contain embedded null bytes.
+Changed the Tcl object-based APIs to take a byte pointer and length pair
+instead of a null-terminated C string. Modified several object type managers
+to support binary strings but not, for example, the list type manager.
+Existing string-based C APIs are unchanged and will truncate binary
+strings. Compiled scripts containing nulls are also truncated. (BL)
+
+12/12/96 (feature change) Removed the commands "cp", "mkdir", "mv",
+"rm", and "rmdir" from the Macintosh version of Tcl.  They were never
+officially supported and their functionality is now available via
+the file command. (RJ)
+
+----------------- Released 8.0a1, 12/20/96 -----------------------
+
+1/7/97 (bug fix) Under Windows, "file stat c:" was returning error instead
+of stat for current dir on c: drive.
+
+1/10/97 (new feature) Added Tcl_GetIndexFromObj procedure for quick
+lookups of keyword arguments. (JO)
+
+1/12/97 (new feature) Serial IO channel drivers for Windows and Unix,
+available by using Tcl open command to open pseudo-files like "com1:" or
+"/dev/ttya".  New option to Tcl fconfigure command for serial files:
+"-mode baud,parity,data,stop" to specify baud rate, parity, data bits, and
+stop bits.  Serial IO is not yet available on Mac.
+
+1/16/97 (feature change) Restored the Tcl7.x "two level substitution
+semantics" for expressions. Expressions not enclosed in braces are
+implemented, in general, by calling the expr command procedure
+(Tcl_ExprObjCmd) at runtime after the Tcl interpreter has already done a
+first round of substitutions. This is slow (about Tcl7.x speed) because new
+code for the expression is generally compiled each time. However, if the
+expression has only variable substitutions (and not command substitutions),
+"optimistic" fast code is generated inline. This inline code will fail if a
+second round of substitutions is needed (i.e., if the value of a substituted
+variable itself requires more substitutions). The optimistic code will
+catch the error and back off to call the slower but guaranteed correct
+expr command procedure. (BL)
+
+1/16/97 (feature improvements) Added Tcl_ExprLongObj and Tcl_ExprDoubleObj
+to round out expression-related procedures. (BL)
+
+1/16/97 (feature change) Under Windows, at startup the environment variables
+"path", "comspec", and "windir" in any capitalization are converted
+automatically to upper case.  The PATH variable could be spelled as path,
+Path, PaTh, etc. and it makes programming rather annoying.  All other
+environment variables are left alone. (CS)
+
+1/20/97 (new features) Rewrote the "lsort" command:
+    - The new version is based on reentrant merge sort code provided
+      by Richard Hipp, so it eliminates the reentrancy and stability
+      problems with the old qsort-based implementation.
+    - The new version supports a -dictionary option for sorting, and
+      it also supports a -index option for sorting lists using one
+      element for comparison.
+    - The new version is an object command, so it works well with the
+      Tcl compiler, especially in conjunction with the new -index
+      option.  When the -index option is used, this version of lsort
+      is more than 100 times faster than the Tcl 7.6 lsort, which had
+      to use the -command option to get the same effect. (JO)
+
+1/20/97 (feature improvements) Added the improved debugging support for Tcl
+objects prototyped by Karl Lehenbauer <karl@hammer1.ops.NeoSoft.com>.
+If TCL_MEM_DEBUG is defined, the object creation calls use Tcl_DbCkalloc
+directly in order to record the caller's source file name and line
+number. (BL)
+
+1/21/97 (removed feature) Desupported the tcl_precision variable: if
+set, it is ignored.  Tcl now uses the full 17 digits of precision when
+converting real numbers to strings (with the new object system real
+numbers are rarely converted to strings so there is no efficiency
+disadvantage to printing all 17 digits; the new scheme improves
+accuracy and simplifies several APIs). (JO)
+*** POTENTIAL INCOMPATIBILITY ***
+
+1/21/97 (feature change) Removed the "interp" argument for the
+procedures Tcl_GetStringFromObj, Tcl_StringObjAppend, and
+Tcl_StringObjAppendObj.  Also removed the "interp" argument for
+the updateStringProc procedure in Tcl_ObjType structures.  With
+the tcl_precision changes above, these are no longer needed. (JO)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a1, but not with Tcl 7.6 ***
+
+1/22/97 (bug fix) Fixed http.tcl so that http_reset does not result in
+an extra call to the command callback.  In addition, if the transaction
+gets a premature eof, the state(status) is "eof", not "ok". (BW)
+
+----------------- Released 8.0a2, 1/24/97 -----------------------
+
+1/29/97 (feature change) Changed how two digit years are parsed in the
+clock command.  The old interface just added 1900 which will seem
+broken by the year 2000.  The new scheme follows the POSIX standard
+and treats dates 70-99 as 1970-1999 and dates 00-38 as 2000-2038.  All
+other two digit dates are undefined. (RJ)
+*** POTENTIAL INCOMPATIBILITY ***
+
+2/4/97 (bug fix) Fixed bug in clock code that dealt with relative
+dates.  Using the relative month code you could get an invalid date
+because it jumped into a non-existant day.  (For example, Jan 31
+to Feb 31.)  The code now will return the last valid day of the
+month in these situations.  Thanks to Hume Smith for sending in
+this bug fix.  (RJ)
+
+2/10/97 (feature change) Eliminated Tcl_StringObjAppend and
+Tcl_StringObjAppendObj procedures, replaced them with Tcl_AppendToObj
+and Tcl_AppendStringsToObj procedures.  Added new procedure
+Tcl_SetObjLength. (JO)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2, but not with Tcl 7.6 ***
+
+2/10/97 (new feature) Added Tcl_WrongNumArgs procedure for generating
+error messages about incorrect number of arguments. (JO)
+
+2/11/97 (new feature, bug fix) http package.  Added -accept to http_config
+so you can set the Accept header.  Added -handler option to http_get so
+you can supply your own data handler.  Also fixed POST operation to
+set the correct MIME type on the request. (BW)
+
+2/22/97 (bug fix) Fixed bug that caused $tcl_platform(osVersion) to be
+computed incorrectly under AIX. (JO)
+
+2/25/97 (new feature, feature change) Added support for both int and long
+integer objects. Added Tcl_NewLongObj/Tcl_GetLongFromObj/Tcl_SetLongFromObj
+procedures and renamed the Tcl_Obj internalRep intValue member to
+longValue. Tcl_GetIntFromObj now checks for integer values too large to
+represent as non-long integers. Changed Tcl_GetAllObjTypes to
+Tcl_AppendAllObjTypes. (BL)
+
+3/5/97 (new feature) Added new Tcl_SetListObj procedure to round out
+collection of procedures that set the type and value of existing Tcl
+objects. (BL)
+
+3/6/97 (new feature) Added -global flag for interp invokehidden. (JL)
+
+3/6/97 (new feature, feature change) Added isNativeObjectProc field to the
+Tcl_CmdInfo structure to indicate (when 1) if the command has an
+object-based command procedure. Removed the nameLength arg from
+Tcl_CreateObjCommand since command names can't contain null characters. (BL)
+
+3/6/97 (bug fix) Fixed bug in "unknown" procedure that caused auto-
+loading to fail on commands whose names begin with digits. (JO)
+
+3/7/97 (bug fix) Auto-loading now works in Safe Base. Safe interpreters
+only accept the Version 2 and onwards tclIndex files. (JL)
+
+3/13/97 (bug fix) Fixed core dump due to interaction between aliases and
+hidden commands. Bug found by Lindsay Marshall. (JL)
+
+3/14/97 (bug fix) Fixed mac bugs relating to time.  The -gmt option
+now adjusts the time in the correct direction.  (Thanks to Ed Hume for
+reporting a fix to this problem.)  Also fixed file "mtime" etc. to
+return times from GMT rather than local time zone.  (RJ)
+
+3/18/97 (feature change) Declaration of objv in Tcl_ObjCmdProc function
+changed from "Tcl_Obj *objv[]" to "Tcl_Obj *CONST objv[]".  All Tcl object
+commands changed to use new declaration of objv.  Naive translation of
+string-based command procs to object-based command procs could very easily
+have yielded code where the contents of the objv array were changed.  This
+is not a problem with string-based command procs, but doing something as
+simple as objv[2] = objv[3] would corrupt the runtime stack and cause Tcl to
+crash.  Introduced CONST in declaration of objv so that attempted assignment
+of new pointer values to elements of the objv array will be caught by the
+compiler. (CCS)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 ***
+
+3/19/97 (bug fix) Fixed panic due to object sharing. The root cause was
+that old code was using Tcl_ResetResult instead of Tcl_ResetObjResult. (JL)
+
+3/20/97 (new feature) Added a new subcommand for the file
+command. file attributes filename can give a list of platform-specific
+options (such as file/creator type on the Mac, permissions on Unix) or
+set the values of them. Added a new subcommand for the file
+command. file nativename name gives back the platform-specific form
+for the file. This is useful when the filename is needed to pass to
+the OS, such as exec under Windows 95 or AppleScript on the Mac. For
+more info, see file.n. (SRP)
+
+3/24/97 (removed feature) Removed the tcl_safePolicyPath procedure. Now
+the policy path is computed from the auto_path by appending the directory
+'policies' to each element. Also fixed several bugs in automatic tracking
+of auto_path by computed policy path. (JL)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 but not with Tcl 7.6 ***
+
+4/8/97 (new feature) If the variable whose name is passed to lappend doesn't
+already exist, and there are no value arguments, lappend now creates the
+variable with an empty value instead of returning an error. Change suggested
+by Tom Tromey. (BL)
+
+4/9/97 (feature change) Changed the name of the TCL_PART1_NOT_PARSED flag to
+TCL_PARSE_PART1. (BL)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 but not with Tcl 7.6 ***
+
+4/10/97 (bug fixes) Fixed various compilation-related bugs:
+    - "UpdateStringOfCmdName should never be invoked" panic.
+    - Bad code generated for expressions not in {}'s inside catch commands.
+    - Segmentation fault in some command procedures when two argument
+      object pointers refer to the same object.
+    - Second level of substitutions were never done for expressions not
+      in {}'s that consist of a single variable reference: e.g.,
+      "set x 27; set bool {$x}; if $bool {puts foo}" would fail with error.
+    - Bad code generated when code storage was grown while compiling some
+      expressions: ones with compilation errors or consisting of only a
+      variable reference.
+    - Bugs involving multiple interpreters: wasn't checking that a
+      procedure's code was compiled for the same interpreter as the one
+      executing it, and didn't invalidate code on hidden-exposed command
+      transitions.
+    - "Bad stack top" panic when executing scripts that require a huge
+      amount of stack space.
+    - Incorrect sharing of code for procedure bodies, and procedure code
+      deallocated before last execution of the procedure finished.
+    - Fixed compilation of expression words in quotes. For example,
+      if "0 < 3" {puts foo}.
+    - Fixed performance bug in array set command with large assignments.
+    - Tcl_SetObjLength segmentation fault setting length of empty object.
+    - If Tcl_SetObjectResult was passed the same object as the interpreter's
+      result object, it freed the object instead of doing nothing. Bug fix
+      by Michael J. McLennan.
+    - Tcl_ListObjAppendList inserted elements from the wrong list. Bug fix
+      by Michael J. McLennan.
+    - Segmentation fault if empty variable list was specified in a foreach
+      command. Bug fix by Jan Nijtmans.
+    - NULL command name was always passed to Tcl_CreateTrace callback
+      procedure.
+    - Wrong string representation generated for the value LONG_MIN.
+      For example, expr 1<<31 printed incorrectly on a 32 bit machine.
+    - "set {a($x)} 1" stored value in wrong variable.
+    - Tcl_GetBooleanFromObj was not checking for garbage after a numeric
+      value.
+    - Garbled "bad operand type" error message when evaluating expressions
+      not surrounded by {}'s. (BL)
+
+4/16/97 (new feature) The expr command now has the "rand()" and
+"srand()" functions for getting random numbers in expr. (RJ)
+
+4/23/97 (bug fix) Fixed core dump in bgerror when the error handler command
+deletes the current interpreter. Found by Juergen Schoenwald. (JL)
+
+4/23/97 (feature change) The notifier interfaces have been redesigned
+to make embedding in applications with external event loops possible.
+A number of interfaces in the notifier and the channel drivers have
+changed.  Refer to the Notifier.3 and CrtChannel.3 manual entries for
+more details. (SS)
+*** POTENTIAL INCOMPATIBILITY ***
+
+4/23/97 (removed feature) The Tcl_File interfaces have been removed.
+The Tcl_CreateFileHandler/Tcl_DeleteFileHandler interfaces now take
+Unix fd's and are only supported on the Unix platform.
+Tcl_GetChannelFile has been replaced with Tcl_GetChannelHandle.
+Tcl_MakeFileChannel now takes a platform specific file handle. (SS)
+*** POTENTIAL INCOMPATIBILITY ***
+
+4/23/97 (removed feature) The modal timeout interface has been
+removed (Tcl_CreateModalTimeout/Tcl_DeleteModalTimeout) (SS)
+*** POTENTIAL INCOMPATIBILITY ***
+
+4/23/97 (feature change) Channel drivers are now required to correctly
+implement blocking behavior when they are in blocking mode. (SS)
+*** POTENTIAL INCOMPATIBILITY ***
+
+4/23/97 (new feature) Added the "binary" command for manipulating
+binary strings. Also, changed the "puts", "gets", and "read" commands
+to preserve embedded nulls.  (SS)
+
+4/23/97 (new feature) Added tcl_platform(byteOrder) element to the
+tcl_platform array to identify the native byte order for the current
+host. (SS)
+
+4/23/97 (bug fix) Fixed bug in date parsing around year boundaries. (SS)
+
+4/24/97 (bug fix) In the process of copying a file owned by another user,
+Tcl was changing the owner of the copy back to the owner of the original
+file, therefore causing further file operations to fail because the current
+user didn't own the copy anymore.  The owner of the copy is now left as the
+current user. (CCS)
+
+4/24/97 (feature change) Under Windows, don't automatically uppercase the
+environment variable "windir" -- it's supposed to be lower case.  (CCS)
+
+4/29/97 (new feature) Added namespace support based on a namespace
+implementation by Michael J. McLennan of Lucent Technologies. A namespace
+encapsulates a collection of commands and variables to ensure that they
+won't interfere the commands and variables of other namespaces. The global
+namespace holds all global variables and commands. Additional namespaces are
+created with the new namespace command. The new variable command lets you
+create Tcl variables inside a namespace. The names of Tcl variables and
+commands may now be qualified by the name of the namespace containing them.
+The key namespace-related commands are summarized below:
+    - namespace ?eval? name arg ?arg...?
+         Used to define the commands and variables in a namespace.
+         Optionally creates the namespace.
+    - namespace export ?-clear? ?pattern pattern...?
+         Specifies which commands are exported from a namespace. These
+         are the ones that can be imported into another namespace.
+    - namespace import ?-force? ?pattern pattern...?
+         Makes the specified commands accessible in the current namespace.
+    - namespace current
+         Returns the name of the current namespace.
+    - variable name ?value? ?name ?value?...?
+         Creates one or more namespace variables. (BTL)
+
+5/1/97 (bug fix) Under Windows, file times were reported in GMT.  Should be
+reported in local time. (CCS)
+
+5/2/97 (feature change) Changed the name of the two Tcl variables used for
+tracing bytecode compilation and execution to tcl_traceCompile and
+tcl_traceExec respectively. These variables are now documented in the
+tclvars man page. (BL)
+
+5/5/97 (new feature) Support "end" as the index for "lsort -index". (BW)
+
+5/5/97 (bug fixes) Cleaned up the way the http package resets connections (BW)
+
+5/8/97 (feature change) Newly created Tcl objects now have a reference count
+of zero instead of one. This simplifies C code that stores newly created
+objects in Tcl variables or in data structures such as list objects. That C
+code must increment the new object's reference count since the variable or
+data structure will contain a long-term reference to the object. Formerly,
+when new objects started out with reference count one, it was necessary to
+decrement the new object's reference count after the store to make sure it
+was left with the correct value; this is no longer necessary. (BL)
+
+5/9/97 (new feature) Added the Tcl_GetsObj interface that takes an
+object reference instead of a dynamic string (as in Tcl_Gets). (SS)
+
+5/12/97 (new feature) Added Tcl_CreateAliasObj and Tcl_GetAliasObj C APIs
+to allow an alias command to be created with a vector of Tcl_Obj structures
+and to get the vector back later. (JL)
+
+5/12/97 (feature change) Changed Tcl_ExposeCommand and Tcl_HideCommand to
+leave an object result instead of a string result. (JL)
+
+5/14/97 (feature change) Improved the handling of the interpreter result.
+This is still either an object or a string, but the two values are now kept
+consistent unless some C code reads or writes interp->result directly. See
+the SetResult man page for details. Removed the Tcl_ResetObjResult
+procedure. (BL)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 ***
+
+5/16/97 (new feature) Added "fcopy" command to move data between
+channels.  Refer to the manual page for more information.  Removed the
+"unsupported0" command since it is obsolete now.  (SS)
+
+5/16/97 (new feature) Added Tcl_GetStringResult procedure to allow programs
+to get an interpreter's result as a string. If the result was previously set
+to an object, this procedure will convert the object to a string. Use of
+Tcl_GetStringResult is intended to replace direct access to interp->result,
+which is not safe. (BL)
+
+5/20/97 (new features) Fixed "fcopy" to return the number of bytes
+transferred in the blocking case.  Updated the http package to use
+fcopy instead of unsupported0.  Added -timeout and -handler options to
+http_get.  http_get is now blocking by default.  It is only non-blocking
+if you supply a -command argument. (BW)
+
+5/22/97 (bug fix) Fixed several bugs in the "lsort" command having to do
+with the -dictionary option and the presence of numbers embedded in the
+strings.  (JO)
+
+----------------- Released 8.0b1, 5/27/97 -----------------------
+
+6/2/97 (bug fix) Fixed bug in startup code that caused a problem in
+finding the library files when they are installed in a directory
+containing a space in the name. (SS)
+
+6/2/97 (bug fix) Fixed bug in Unix notifier where the select mask was
+not being cleared under some circumstances. (SS)
+
+6/4/97 (bug fix) Fixed bug that prevented creation of Tk widgets in
+namespaces. Tcl_CreateObjCommand and Tcl_CreateCommand now always create
+commands in the global namespace unless the command names are qualified. Tcl
+procedures continue to be created in the current namespace by default. (BL)
+
+6/6/97 (new features) Added new namespace API procedures
+Tcl_AppendExportList and Tcl_Export to allow C code to get and set a
+namespace's export list. (BL)
+
+6/11/97 (new feature) Added Tcl_ConcatObj. This object-based routine
+parallels the string-based routine Tcl_Concat. (SRP)
+
+6/11/97 (new feature) Added Tcl_SetObjErrorCode. This object-based
+routines parallels the string-based routine Tcl_SetErrorCode. (SRP)
+
+6/12/97 (bug fix) Fix the "unknown" procedure so that wish under Windows
+will exec an external program, instead of always complaining "console1 not
+opened for writing". (CCS)
+
+6/12/97 (bug fix) Fixed core dump experienced by the following simple
+script:
+	interp create x
+	x alias exec exec
+	interp delete x
+This panic was caused by not installing the new CmdDeleteProc when exec
+got redefined by the alias creation step. Reported by Lindsay Marshal (JL)
+
+6/13/97 (new features) Tcl objects newly created by Tcl_NewObj now have a
+string representation that points to a shared heap string of length 1. (They
+used to have NULL bytes and typePtr fields. This was treated as a special
+case to indicate an empty string, but made type manager implementations
+complex and error prone.) The new procedure Tcl_InvalidateStringRep is used
+to mark an object's string representation invalid and to free any storage
+associated with the old string representation. (BL)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl7.6 ***
+
+6/16/97 (bug fix) Tcl_ScanCountedElement could leave braces unmatched
+if the string ended with a backslash. (JO)
+
+6/17/97 (bug fix) Fixed channel event bug where readable events would be
+lost during recursive events loops if the input buffers contained
+data. (SS)
+
+6/17/97 (bug fix) Fixed bug in Windows socket code that didn't
+reenable read events in the case where an external entity is also
+reading from the socket. (SS)
+
+6/18/97 (bug fix) Changed initial setting of the notifier service mode
+to TCL_SERVICE_NONE to avoid unexpected event handling during
+initialization. (SS)
+
+6/19/97 (bug fix/feature change) The command callback to fcopy is now
+called in case of errors during the background copy.  This adds a second,
+optional argument to the callback that is the error string.  The callback
+in case of errors is required for proper cleanup by the user of fcopy. (BW)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 ***
+
+6/19/97 (bug fix) Fixed a panic due to the following four line script:
+	interp create x
+	x alias foo bar
+	x eval rename foo blotz
+	x alias foo {}
+The problem was that the interp code was not using the actual current name
+of the command to be deleted as a result of un-aliasing foo. (JL)
+
+6/19/97 (feature change) Pass interp down to the ChannelOption and
+driver specific calls so system errors can be differentiated from syntax
+ones. Changed Tcl_DriverGetOptionProc type. Affects Tcl_GetChannelOption,
+TcpGetOptionProc,  TtyGetOptionProc, etc. (DL)
+*** POTENTIAL INCOMPATIBILITY ***
+
+6/19/97 (new feature) Added Tcl_BadChannelOption for use by by driver
+specific option procedures (Set and Get) to return a complete and
+meaningful error message. (DL)
+
+6/19/97 (bug fixes) If a system call error occurs while doing an
+fconfigure on tcp or tty/com channel: return the appropriate error
+message (instead of the syntax error one or none). (Fixed for Unix and
+most of the Win and Mac drivers). (DL)
+
+6/20/97 (feature change) Eval is no longer assumed as the subcommand name
+in namespace commands: you must now write "namespace eval nsName {...}".
+Abbreviations of namespace subcommand names are now allowed. (BL)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl7.6 ***
+
+6/20/97 (feature change) Changed the errorInfo traceback message for
+compilation errors from "invoked from within" to "while compiling". (BL)
+
+6/20/97 (bug fixes) Fixed various compilation-related bugs:
+    - "UpdateStringOfCmdName should never be called" and
+      "UpdateStringOfByteCode should never be called" panics.
+    - Segfault in TclObjInterpProc getting procedure name after evaluation
+      stack is reallocated (grown).
+    - Could not use ":" at end of variable and command names.
+    - Bad code generated for while and for commands with test expressions
+      enclosed in quotes: e.g., "set i 0; while "$i > 5" {}".
+    - Command trace procedures would crash if they did a Tcl_EvalObj that
+      reallocated the evaluation stack.
+    - Break and continue commands did not reset the interpreter result.
+    - The Tcl_ExprXXX routines, both string- or object-based, always
+      modified the interpreter result even if there was no error.
+    - The argument parsing procedure used by several compile procedures
+      always treated "]" as end of a command: e.g., "set a ]" would fail.
+    - Changed errorInfo traceback message for compilation errors from
+      "invoked from within" to "while compiling".
+    - Problem initializing Tcl object managers during interpreter creation.
+    - Added check and error message if formal parameter to a procedure is
+      an array element. (BL)
+
+6/23/97 (new feature) Added "registry" package to allow manipulation
+of the Windows system registry.  See manual entry for details. (SS)
+
+6/24/97 (feature change) Converted http to a package and added the
+http1.0 subdirectory of the Tcl script library.  This means you have
+to do a "package require http" to use this, as advertised in the man page. (BW)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 ***
+
+6/24/97 (bug fix) Ensure that Tcl_Set/GetVar C APIs, when called without
+TCL_LEAVE_ERR_MSG, don't touch the interp result. (DL)
+
+6/26/97 (feature change) Changed name of Tcl_ExprStringObj to
+Tcl_ExprObj. (BL)
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 ***
+
+----------------- Released 8.0b2, 6/30/97 -----------------------
+
+7/1/97 (new feature) TCL_BUILD_SHARED flag set in tclConfig.sh
+when Tcl has been built with --enable-shared. A new tclLibObjs
+make target, echoing the list of the .o's needed to build a tcl
+library, is now provided. (DL)
+
+7/1/97 (feature change) compat/getcwd.c removed and changed the
+only place where getcwd is used so a new USEGETWD flag selects
+the use of the replacement "getwd". Adding this flag is recommended
+for SunOS 4 (because getcwd on SunOS 4 uses a pipe to pwd(1)!). (DL)
+
+7/7/97 (feature change) The split command now supports binary data (i.e.,
+null characters in strings). (BL)
+
+7/7/97 (bug fix) string first returned the wrong result if the first
+argument string was empty. (BL)
+
+7/8/97 (bug fix) Fixed core dump in fcopy that could occur when a command
+callback was supplied and an error or eof condition caused no background
+activity.  A refcount bug triggered a panic in Tcl_ListObjAppendElement. (BW)
+
+7/8/97 (bug fix) Relaxed the pattern matching on http_get so you do not
+need a trailing path component.  You can now get away with just
+http_get www.scriptics.com					(BW)
+
+7/9/97 (bug fix) Creating anonymous interpreters no longer smashes existing
+commands with names similar to the generated name. Previously creating an
+anonymous interpreter could smash an existing command, now it skips until
+it finds a command name that isn't being used. (JL)
+
+7/9/97 (feature change) Removed the policy management mechanism from the
+Safe Base; left the aliases to source and load modules, and to do a limited
+form of the "file" command. See entry of 11/15/96. (JL)
+
+7/9/97 (bug fixes) Fixed various compilation-related bugs:
+    - Line numbers in errorInfo now are the same as those in Tcl7.6 unless
+there are compilation errors. Compilation error messages now include the
+entire command in error.
+    - Trailing ::s after namespace names weren't being ignored.
+    - Could not refer to an namespace variable with an empty name using a
+name of the form "n::". (BL)
+
+7/9/97 (bug fix) Fixed bug in Tcl_Export that prevented you from exporting
+from other than the current namespace. (BL)
+
+7/9/97 (bug fix) env.test was removing env var needed for proper finding
+of libraries in child process. (DL)
+
+7/10/97 (bug fixes/new feature) Cleanup in Tcl_MakeSafe. Less information
+is leaked to safe interps. Error message fixes for interp sub commands.
+Likewise changes in safealias.tcl; tcl_safeCreateInterp can now be called
+without argument to generate the slave name (like in interp create). (DL)
+
+7/10/97 (bug fixes) Bytecode compiler now generates more detailed
+command location information: subcommands as well as commands now have
+location information. This means command trace procedures now get the
+correct source string for each command in their command parameter. (BL)
+
+7/22/97 (bug fixes) Performance improvement in Safe interpreters
+handling. Added new mask value to (tclInt.h) Interp.flags record. (DL)
+
+7/22/97 (bug fix) Fixed panic in 'interp target {} foo'. This bug
+was present since Tcl 7.6. (JL)
+
+7/22/97 (bug fix) Fixed bug in compilation of procedures in namespaces: the
+procedure's namespace must be used to look up compile procedures, not the
+current namespace. (BL)
+
+7/22/97 (bug fix) Use of the -channel option of http_get was not setting
+the end of line translations mode on the channel, so copying binary data
+with the -channel option was corrupting the result on non-unix platforms. (BW)
+
+7/22/97 (bug fixes) file commands and ~user (seg fault and other
+improper returns). (DL)
+
+7/23/97 (feature change) Reenabled "vwait" in Safe Base. (JL)
+
+7/23/97 (bug fixes) Fixed two bugs involving read traces on array variables
+in procedures: trace procedures were sometimes not called, and reading
+nonexistant array elements didn't create undefined element variables that
+could later be defined by trace procedures. (BL)
+
+7/24/97 (bug fix) Windows memory allocation performance was
+superlinear in some cases.  Made the Mac allocator generic and changed
+both the Mac and Windows platforms to use the new allocator instead of
+malloc and free. (SS)
+
+7/24/97 - 8/12/97 (bug fixes/change of features) Completely revamped safe
+sourcing/loading (see safe.n) to hide pathnames, use virtual
+paths tokens instead, improved security in several respects and made it
+more tunable. Multi level interp loading can work too now. Package auto
+loading now works in safe interps as long as the package directory is in
+the auto_path (no deep crawling allowed in safe interps). (DL)
+*** POTENTIAL INCOMPATIBILITY with previous alpha and beta releases ***
+
+7/24/97 (bug fixes) Made Tcl_SetVar* and Tcl_NewString* treat a NULL value
+as an empty string. (This fixes hairy crash case where you would crash
+because load command for other interps assumed presence of
+errorInfo...). (DL)
+
+7/28/97 (bug fix) Fixed pkg_mkIndex to understand namespaces.  It will
+use the export list of a namespace and create auto_index entries for
+all export commands.  Those names are in their fully qualified form in the
+auto_index.  Therefore, I tweaked unknown to try both $cmd and ::$cmd.
+Also fixed pkg_mkIndex so you can have "package require" commands inside
+your packages.  These commands are ignored, which is mostly ok except
+when you must load another package before loading yours because of
+linking dependencies. (BW)
+
+7/28/97 (bug fix) A variable created by the variable command now persists
+until the namespace is destroyed or the variable is unset. This is true even
+if the variable has not been initialized; these variables used to be
+destroyed if an error occurred when accessing them. In addition, the "info
+vars" command lists uninitialized namespace variables, while the "info
+exists" command returns 0 for them. (BL)
+
+7/29/97 (feature change)  Changed the http package to use the ::http
+namespace. http_get renamed to http::geturl, http_config renamed to
+http::config, http_formatQuery renamed to http::formatQuery.
+It now provides the 2.0 version of the package.
+The 1.0 version is still available with the old names.
+*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b2 but not with Tcl 7.6 ***
+
+7/29/97 (bug fix, new feature) Tcl_Main now uses Tcl objects internally to
+preserve NULLs in commands and command output. Added new API procedure
+Tcl_RecordAndEvalObj that resembles Tcl_RecordAndEval but takes an object
+containing a command. (BL)
+
+7/30/97 (bug fix) Tcl freed strings in the environ array even if it
+did not allocate them. (SS)
+
+7/30/97 (bug fix) If a procedure is renamed into a different namespace, it
+now executes in the context of that namespace. (BL)
+
+7/30/97 (bug fix) Prevent renaming of commands into and from namespaces as
+part of hiding them. (JL)
+
+7/31/97 (feature change) Moved the history command from C to tcl.
+This uses the ::history namespace.  The "words" and "substitute" options
+are no longer supported.  In addition, the "keep" option without a value
+returns the current keep limit.  There is a new "clear" option.
+The unknown command now supports !! again. (BW)
+*** POTENTIAL INCOMPATIBILTY  ***
+
+7/30/97 (bug fix) Made sure that a slave can not fool the master into
+hiding the wrong command. Made sure we don't crash in hiding + namespaces
+issues. (DL)
+
+8/4/97 (bug fix) Concat, eval, uplevel, and similar commands were
+incorrectly trimming trailing space characters from their arguments
+even when the space characters were preceded by a backslash. (JO)
+
+8/4/97 (bug fix) Removed the hard link between bgerror and tkerror.
+Only bgerror is supported in tcl core. Tk will still look for a
+tkerror but using regular tcl code for that feature. (DL)
+*** POTENTIAL INCOMPATIBILTY with code relying on the hard link ***

+8/6/97 (bug fix) Reduced size required for compiled bytecodes by using a
+more compact encoding for the command pc-to-source map. (BL)
+
+8/6/97 (new feature) Added support for additional compilation and execution
+statistics when Tcl is compiled with the TCL_COMPILE_STATS flag. (BL)
+
+8/7/97 (bug fix) Expressions not in {}s that have a comparison operator as
+the topmost operator must be compiled out-of-line (call the expr cmd at
+runtime) to properly support expr's two-level substitution semantics. An
+example is "set a 2; set b {$a}; puts [expr $b == 2]". (BL)
+
+8/11/97 (bug fix) The catch command would sometimes crash if a variable name
+was given and the bytecode evaluation stack was grown when executing the
+argument script. (BL)
+
+8/12/97 (feature change) Reinstated the variable tcl_precision to control
+the number of digits used when floating-point values are converted to
+strings, with default of 12 digits.  However, had to make tcl_precision
+shared among all interpreters (except that safe interpreters can't
+modify it).  This makes the Tcl 8.0 behavior almost identical to 7.6
+except that the default precision is 12 instead of 6. (JO)
+*** POTENTIAL INCOMPATIBILITY ***
+
+----------------- Released 8.0, 8/18/97 -----------------------
+
+8/19/97 (bug fix) Minimal fix for glob -nocomplain bugs:
+"glob -nocomplain unreadableDir/*" was generating an anonymous
+error. More in depth fixes will come with 8.1. (DL).
+
+8/20/97 (bug fix) Removed check for FLT_MIN in binary command so
+underflow conditions are handled by the compiler automatic
+conversions. (SS)
+
+8/20/97 (bug fixes) Fixed several compilation-related bugs:
+    - Array cmd wasn't detecting arrays that, while compiled, do not yet
+      exist (e.g., are marked undefined since they haven't been assigned
+      to yet).
+    - The GetToken procedure in tclCompExpr.c wasn't recognizing properly
+      whether an integer token was invalid. For example, "0x$" is not
+      a valid integer.
+    - Performance bug in TclExecuteByteCode: the size of its stack frame
+      was reduced by over 20% by moving errorInfo code elsewhere.
+    - Uninitialized memory read error in tclCompile.c. (BL)
+
+8/21/97 (bug fix) safe::interpConfigure now behave like Tk widget's
+configure : it changes only the options you provide and you can get
+the current value of any single option. New ?-nested boolean? and
+?-statics boolean? for all safe::interp* commands but we still
+accept (upward compatibility) the previously defined non valued
+flags ?-noStatics? and ?-nestedLoadOk?. Improved the documentation. (DL).
+
+8/22/97 (bug fix) Updated PrintDbl.3 to reflect the fact that the
+tcl_precision variable is still used and that it is now shared by all
+interpreters. (BL)
+
+8/25/97 (bug fix) Fixed array access bug in IllegalExprOperandType
+procedure in tclExecute.c: it was not properly supporting the || and &&
+operators. (BL)
+
+8/27/97 (bug fix) In cases where a channel handler was created with an
+empty event mask while data was still buffered in the channel, the
+channel code would get stuck spinning on a timer that would starve
+idle handlers.  This mostly happened in Tk when reading from stdin. (SS)
+
+9/4/97 (bug fix) Slave interps now inherit the maximum recursion limit
+of their parent instead of starting back at the default. {nb: this still
+does not prevent stack overflow by multi-interps recursion or aliasing} (DL)
+
+9/11/97 (bug fix) An uninitialized variable in Tcl_WaitPid caused
+pipes to fail to report eof properly under Windows. (SS)
+
+9/12/97 (bug fix) "exec" was misidentifying some DOS executables as not
+executable. (CCS)
+
+9/14/97 (bug fix) Was using the wrong structure in sizeof operation in
+tclUnixChan.c. (JL)
+
+9/15/97 (bug fix) Fixed notifier to break out of do-one-event loop if
+Tcl_WaitForEvent returns 1, so that callers of Tcl_DoOneEvent will get
+a chance to check whether the event just handled is significant. This
+affected mainly recursive calls to Tcl_VWaitCmd; these did not get a
+chance to notice that the variable they were waiting for has been set
+and thus they didn't terminate the vwait. (JL, DL, SS)
+
+9/15/97 (bug fix) Alignment problems in "binary format" would cause a
+crash on some platforms when formatting floating point numbers. (SS)
+
+9/15/97 (bug fix) Fixed bug in Macintosh socket code.  Now passes all
+tests in socket.test that are not platform specific. (Thanks to Mark
+Roseman for the pointer on the fix.)  (RJ)
+
+9/18/97 (bug fix) Fixed bug -dictionary option of lsort that could
+cause the compare function to run off the end of an array if the
+number only contained 0's. (Thanks to Greg Couch for the report.) (RJ)
+
+9/18/97 (bug fix) TclFinalizeEnvironment was not cleaning up
+properly. (DL, JI)
+
+9/18/97 (bug fix) Fixed long-standing bug where an "array get" command
+did not trigger traces on the array or its elements. (BL)
+
+9/18/97 (bug fixes) Fixed compilation-related bugs:
+    - Fixed errorInfo traceback information for toplevel coomands that
+      contain nested commands.
+    - In the expr command, && and || now accept boolean operands as well
+      as numeric ones. (BL)
+
+9/22/97 (bug fix) Fixed bug that prevented translation modes from being
+set independently for input and output on sockets if input was "auto". (JL)
+
+9/24/97 (bug fix) Tcl_EvalFile(3) and thus source(n) now works fine on
+files containing NUL chars. (DL)
+
+9/26/97 (bug fix) Fixed use of uninitialized memory in the environ array
+that later could cause random core dumps. Applies to all platforms. (JL)
+
+9/26/97 (bug fix) Fixed use of uninitialized memory in socket address data
+structure under some circumstances. This could cause random core dumps.
+This applies only to Unix. (JL)
+
+9/26/97 (bug fix) Opening files on PC-NFS volumes would cause a hang
+until the system timed after the file was closed. (SS)
+
+10/6/97 (bug fix) The join(n) command, though objectified, was loosing
+NULs in the joinString and in list elements after the 2nd one.
+Now you can "join $list \0" for instance. (DL)
+
+10/9/97 (bug fix) Under windows, if env(TMP) or env(TEMP) referred to a
+non-existent directory, exec would fail when trying to create its temporary
+files. (CCS)
+
+10/9/97 (bug fix) Under mac and windows, "info hostname" would crash if
+sockets were installed but the hostname could not be determined anyhow.
+Tcl_GetHostName() was returning NULL when it should have been returning
+an empty string. (CCS)
+
+10/10/97 (bug fix) "file attribute /" returned error on windows. (CCS)
+
+10/10/97 (bug fix) Fixed the auto_load procedure to handle procedures
+defined in namespaces better.  Also fixed pgk_mkIndex so it sees procedures
+defined in nested namespaces.  Index entries are still only made for
+exported procedures. (BW)
+
+10/13/97 (bug fix) On unix, for files with unknown group or owner
+attributes, querying the "file attributes" would return an error rather than
+returning the group's or owner's id number, although tha command accepts
+numbers when setting the file's group or owner.  (CCS)
+
+10/22/97 (bug fix) "fcopy" did not eval the callback script at the
+global scope. (SS)
+
+10/22/97 (bug fix) Fixed the signature of the CopyDone callback used in
+the http package(s) so they can handle error cases properly. (BW)
+
+10/28/97 (bug fixes) Fixed a problem where lappend would free the Tcl object
+in a variable if a Tcl_ObjSetVar2 failed because of an error calling a trace
+on the variable. (BL)
+
+10/28/97 (bug fix) Changed binary scan to properly handle sign
+extension of integers on 64-bit or larger machines. (SS)
+
+11/3/97 (bug fixes) Fixed several bugs:
+    - expressions such as "expr ($x)" must be compiled out-of-line
+      (call the expr command procedure at runtime) to ensure the correct
+      behavior when "$x" is an expression such as "5+10".
+    - "array set a {}" now creates a new array var with an empty array
+      value if the var didn't already exist.
+    - "lreplace $foo end end" no longer returns an error (just an empty
+      list) if foo is empty.
+    - upvar will no longer create a variable in a namespace that refers
+      to a variable in a procedure.
+    - deleting a command trace within a command trace callback would
+      make the code that calls traces to reference freed memory.
+    - significantly sped up "string first" and "string last" (fix from
+      darrel@gemstone.com).
+    - seg fault in Tcl_NewStringObj() when a NULL is passed as the byte
+      pointer argument and Tcl is compiled with -DTCL_MEM_DEBUG.
+    - documentation and error msg fixes. (BL)
+
+11/3/97 (bug fix) Fixed a number of I/O bugs related to word sizes on
+64-bit machines. (SS)
+
+11/6/97 (bug fix) The exit code of the first process created by Tcl
+on Windows was not properly reported due to an initialization
+problem. (SS)
+
+----------------- Released 8.0p1, 11/7/97 -----------------------
+
+11/19/97 (bug fix) Fixed bug in linsert where it sometimes accidently
+cleared out a shared argument list object. (BL).
+
+11/19/97 (bug fix) Autoloading in namespaces was not working properly.
+auto_mkindex is still not really namespace aware but most common
+cases should now be handled properly (see init.test). (BW, DL)
+
+11/20/97 (enhancement) Made the changes required by the new Apple
+Universal Headers V.3.0, so that Tcl will compile with CW Pro 2.
+
+11/24/97 (bug fix) Fixed tests in clock test suite that needed the
+-gmt flag set.  Thanks to Jan Nijtmans for reporting the problem. (RJ)
+
+----------------- Released 8.0p2, 11/25/97 -----------------------
+
+12/3/97 (bug fix/optimization) Removed uneeded and potentially dangerous
+instances of double evaluations if "if" and "expr" statements from
+the library files. It is recommended that unless you need a double
+evaluation you always use "expr {...}" instead of "expr ..." and
+"if {...} ..." instead of "if ... ...". It will also be faster
+thanks to the byte compiler. (DL)
+
+---- Shipped as part of the plugin2.0b5 as 8.0p2Plugin1, Dec 8th 97 ----
+
+12/8/97 (bug fix) Need to protect the newly accepted channel in an
+accept callback on a socket, otherwise the callback may close it and
+cause an error, which would cause the C code to attempt to close the
+now deleted channel. Bumping the refcount assures that the channel sticks
+around to be really closed in this case. (JL)
+
+12/8/97 (bug fix) Need to protect the channel in a fileevent so that it
+is not deleted before the fileevent handler returns. (CS, JL)
+
+12/18/97 (bug fix) In the opt argument parsing package: if the description
+had only flags, the "too many arguments" case was not detected. The default
+value was not used for the special "args" ending argument. (DL)
+
+1/15/98 (improvement) Moved common part of initScript in common file.
+Moved windows specific initialization to init.tcl so you can initialize
+Tcl in windows without having to call Tcl_Init which is now only
+searching for init.tcl {back ported from 8.1}. (DL)
+
+---- Shipped as part of the plugin as 8.0p2Plugin2, Jan 15th 98 ----
+
+5/27/98 (bug fix) Windows socket driver did not notice new data arriving
+on nonblocking sockets until the event loop was entered. (SS)
+
+5/27/98 (bug fix) Windows socket driver used FIONREAD, which is not
+supported correctly by WinSock. (SS)
+
+6/9/98 (bug fix) Generic channel code failed to report readable file
+events on buffered data that was left behind by a gets or read that
+did not consume all available data. (SS)
+
+6/18/98 (bug fix) Compilation of loop expressions was too aggressive
+and incorrectly inlined non-literal expressions. (SS)
+
+6/18/98 (bug fix) "info var" and "info locals" incorrectly reported
+the existence of compiler temporary variables. (SS)
+
+6/18/98 (bug fix) Dictionary sorting used signed character
+comparisons. (SS)
+
+6/18/98 (bug fix) Compile procs corrupted the exception stack in some
+cases. (SS)
+
+6/18/98 (bug fix) Array set had erratic behavior when initializing a
+variable from an empty value list. (SS)
+
+6/18/98 (bug fix) The Windows registry package had a bad bounds check
+that could lead to a crash. (SS)
+
+6/18/98 (bug fix) The foreach compile proc did not correctly handle
+non-local variable references. (SS)
+
+6/25/98 (new features) Added name resolution hooks to support [incr Tcl].
+There are new internal Tcl_*Resolver* APIs to add, query and remove the hooks.
+With this changes it should be possible to dynamically load [incr Tcl]
+as an extension. (MM)
+
+7/1/97 (bug fix) The commands "info args, body, default, procs" did
+not correctly handle imported procedures. (RJ)
+
+7/6/98 (improvement) pkg_mkIndex now implements the "package require"
+command.  This makes it possible to create index files for packages
+that require another package and then execute code from that package in
+their file. Previously, this would throw an error because the required
+package had not been loaded.  The -nopkgrequied flag is provided to
+revert back to the old functionality. (EMS)
+
+7/6/98 (improvement) back-ported the -direct flag from 8.1 into
+pkg_mkIndex.  This results in pkgIndex.tcl files that contain direct
+source or load commands instead of tclPkgSetup commands. (EMS)
+
+7/6/98 (improvement) made changes to the AuxData items structures to support
+storage of compiled scripts on disk. Also some related minor changes in
+the compilation and execution engine. (EMS)
+
+6/4/98 (enhancement) Added new internal routines to support inserting
+and deleting from the stat, access, and open-file-channel mechanisms.
+TclAccessInsertProc, TclStatInsertProc, & TclOpenFileChannelInsertProc
+insert pointers to such routines; TclAccessDeleteProc, TclStatDeleteProc,
+& TclOpenFileChannelDeleteProc delete pointers to such routines.  See
+the file generic/tclIOUtils.c for more details. (SKS)
+
+7/1/98 (enhancement) Added a new internal C variable
+tclPreInitScript.  This is a pointer to a string that may hold an
+initialization script; If this pointer is non-NULL it is evaluated in
+Tcl_Init() prior to the built-in initialization script defined in the
+file generic/tclInitScript.h.  (SKS)
+
+7/6/98 (bug fix) Removed dead code in PlatformInitExitHandler so that
+the TCL_LIBRARY value can be safely patched in binaries. (BW)
+
+7/24/98 (enhancement) Incorporated a new version of auto_mkindex that
+can support the [incr Tcl] class structures.  This version will index
+all procedures in a source file, not just those where "proc" starts
+at the beginning of the line.  If you want the old behavior, use the
+auto_mkindex_old procedure. (MM)
+
+7/24/98 (feature change) Changed the Windows registry key to be
+HKEY_LOCAL_MACHINE\Software\Scriptics\Tcl\8.0, and to store the path
+in the default value instead of "Root".  Also, this key can be
+specified at compile time in case Tcl is being used in a different
+context where it needs an alternate library path from the standard Tcl
+installation. (SS)
+
+7/24/98 (feature change) Changed the search order for init.tcl.  The
+tcl_library variable can now be set before calling Tcl_Init to avoid
+doing any searches.  If it isn't set, then Tcl checks
+env(TCL_LIBRARY), the static value set at compile time, an install
+directory relative to the executable, a source directory relative to
+the executable, and a tcl directory relative to the source heirarchy
+containing the executable.  See the comment at the top of
+generic/tclInitScript.h for more details. (SS)
+
+7/27/98 (config change) Changed the use of the DBGX flag in configure.in
+and the makefile to be TCL_DBGX.  Users of tclConfig.sh may need to pass
+this through their configure files with AC_SUBST. (BW)
+
+729/98 (bug fix) Changed [info body] to return a copy of the body of a
+compiled procedure instead of the body itself, to avoid invalidation
+of the internal rep and loss of the byte-codes. (EMS)
+
+8/5/98 (bug fix) The platform init code could walk off the end of a
+buffer when reading the PkgPath registry value on Windows. (SS)
+
+8/5/98 (Windows makefile change) Introduced a set of macros to deal with
+exporting symbols when compiling DLLS on Windows. See win/README for
+details. (EMS)
+
+8/5/98 (addendum) Added a second Windows registry key under
+HKEY_LOCAL_MACHINE\Software\Scriptics\Tcl\8.0, named "pkgPath".
+This is a multi-string value used to initialize the tcl_pkgPath
+variable. This is required if extension DLLs are in architecture specific
+subdirectories. (SS)
+
+8/6/98 (new feature) Added tcl_findLibrary to init.tcl for use by
+extensions, including Tk.  This searches in a canonical way for
+an extensions library directory and initialization file. (BW)
+
+8/10/98 (bug fix) Imported commands used to get lost if the target
+of the import was redefined.  Tcl_CreateCommand and Tcl_CreateObjCommand
+were updated to restore import links. (Note that if you rename a command,
+the import links move to the new name, and if you delete a command then
+the import links get lost. These semantics have not changed.) (MC)
+
+-------- Released 8.0.3 to the Tcl Consortium CD-ROM project, 8/10/98 ------
+
+9/3/98 (bug fix) Tcl_Realloc was failing under Windows because the
+GlobalReAlloc API was not correctly re-allocating blocks that were
+32k+.  The fix was to use newer Win32 APIs (HeapAlloc, HeapFree, and
+HeapReAlloc.) (BS)
+
+10/5/98 (bug fix) Fixed bug in pkg_mkIndex that caused some files that do
+a "package require" of packages in the Tcl libraries to give a warning like
+	warning: "xx.tcl" provides more than one package ({xx 2.0} {yy 0.3})
+and generate a broken pkgIndex.tcl file. (EMS)
+
+10/5/98 (bug fix) Pkg_mkIndex was not doing a case-insensitive comparison
+of extensions to determine whether to load or source a file. Thus, under
+Windows, MYDLLNAME.DLL was sourced, and mydllname.dll loaded. (EMS)
+
+10/5/98 (new feature) Created a new Tcl_Obj type, "procbody". This object's
+internal representation holds a pointer to a Proc structure. Extended
+TclCreateProc to take both strings and "procbody". (EMS)
+
+10/13/98 (bug fix) The "info complete" command can now handle strings
+with NULLs embedded.  Thanks to colin@field.medicine.adelaide.edu.au
+for providing this fix. (RJ)
+
+10/13/98 (bug fix) The "lsort -dictionary" command did not properly
+handle some numbers starting with 0.  Thanks to Richard Hipp
+<drh@acm.org> for submitting the fix to Scriptics. (RJ)
+
+10/13/98 (bug fix) The function Tcl_SetListObj was creating an invalid
+Tcl_Obj if the list had zero elements (despite what the comments said
+it would do).  Thanks to Sebastian Wangnick for reporting the
+problem. (RJ)
+
+10/20/98 (new feature) Added tcl_platform(debug) element to the
+tcl_platform array on Windows platform.  The existence of the debug
+element of the tcl_platform array indicates that the particular Tcl
+shell has been compiled with debug information.  Using
+"info exists tcl_platform(debug)" a Tcl script can direct the
+interpreter to load debug versions of DLLs with the load
+command. (SKS)
+
+10/20/98 (feature change) The Makefile and configure scripts have been
+changed for IRIX to build n32 binaries instead of the old 32 abi
+format.  If you have extensions built with the o32 abi's you will need
+to update them to n32 for them to work with Tcl.  (RJ)
+*** POTENTIAL INCOMPATIBILITY ***
+
+10/23/98 (bug fix) tcl_findLibrary had a stray ] in one of the
+pathnames it searched for the initialization script.  tclInitScript.h
+was incorrectly adding the parent of tcl_library to tcl_pkgPath.  This
+logic was moved into init.tcl, and the initialization of auto_path was
+documented.  Thanks to Donald Porter and Tom Silva for related
+patches. (BW)
+
+10/29/98 (bug fix) Fixed Tcl_NotifyChannel to use Tcl_Preserve instead
+of Tcl_RegisterChannel so that 1) unregistered channels do not get
+closed after their first fileevent, and 2) errors that occur during
+close in a fileevent script are actually reflected by the close
+command. (BW)
+
+10/30/98 (bug fix) Overhaul of pkg_mkIndex to deal with transitive
+package requires and packages split among scripts and binary files.
+Also fixed ommision of global for errorInfo in tcl_findLibrary. (BW)
+
+11/08/98 (bug fix) Fixed the resource command to always detect
+the case where a file is opened a second time with the same
+permissions.  IM claims that this will always cause the same
+FileRef to be returned, but in MacOS 8.1+, this is no longer the case,
+so we have to test for this explicitly. (JI)
+
+11/10/98 (feature change) When compiling with Metrowerk's MSL, use the
+exit function from MSL rather than ExitToShell.  This allows MSL to
+clean up its temporary files. Thanks to Vince Darley for this
+improvement. (JI)
+
+----------------- Released 8.0.4, 11/19/98 -------------------------
+
+11/20/98 (bug fix) Handle possible NULL return in TclGetStdFiles. (RJ)
+
+11/20/98 (bug fix) The dltests would not build on SGI.  They reported
+that you could not mix n32 with 032 binaries.  The configure script
+has been modified to get the EXTRA_CFLAGS from the tcl configure
+script.  [Bug id: 840] (RJ)
+
+12/3/98 (bug fix) Windows NT creates sockets so they are inheritable
+by default.  Fixed socket code so it turns off this bit right after
+creation so sockets aren't kept open by exec'ed processes. [Bug: 892]
+Thanks to Kevin Kenny for this fix.  (SS)
+
+1/11/98 (bug fix)  On HP, "info sharedlibextension" was returning
+empty string on static apps.  It now always returns ".sl".  (RJ)
+
+1/28/99 (configure change) Now support -pipe option on gcc.  (RJ)
+
+2/2/99 (bug fix) Fixed initialization problem on Windows where no
+searching for init.tcl would be performed if the registry keys were
+missing.  (stanton)
+
+2/2/99 (bug fix) Added support for HKEY_PERFORMANCE_DATA and
+HKEY_DYN_DATA keys in the "registry" command. (stanton)
+
+2/2/99 (bug fix) ENOTSUP and EOPNOTSUPP clashed on some Linux
+variants. (stanton)
+
+2/2/99 (enhancement) The "open" command has been changed to use the
+object interfaces. (stanton)
+
+2/2/99 (bug fix) In some cases Tcl would crash due to an overflow of
+the exception stack resulting from a missing byte code in some
+expressions. (stanton)
+
+2/2/99 (bug fix) Changed configure so Linux and IRIX shared libraries
+are linked with the system libraries. (stanton)
+
+2/2/99 (bug fix) Added support for BSDI 4.x (BSD/OS-4*) to the
+configure script. (stanton)
+
+2/2/99 (bug fix) Fixed bug where upvar could resurrect a namespace
+variable after the namespace had been deleted. (stanton)
+
+2/2/99 (bug fix) In some cases when creating variables, the
+interpreter result was being modified even if the TCL_LEAVE_ERR_MSG
+flag was set. (stanton)
+
+2/2/99 (bug fix & new feature) Changed the socket drivers to properly
+handle failures during an async socket connection.  Added a new
+fconfigure option "-error" to retrieve the failure message.  See the
+socket.n manual entry for details. (stanton)
+
+2/2/99 (bug fix) Deleting a renamed interp alias could result in a
+panic. (stanton)
+
+2/2/99 (feature change/bug fix) Changed the behavior of "file
+extension" so that it splits at the last period.  Now the extension of
+a file like "foo..o" is ".o" instead of "..o" as in previous versions.
+*** POTENTIAL INCOMPATIBILITY ***
+
+----------------- Released 8.0.5, 3/9/99 -------------------------
+
+======== Changes for 8.0 go above this line ========
+======== Changes for 8.1 go below this line ========
+
+6/18/97 (new feature) Tcl now supports international character sets:
+    - All C APIs now accept UTF-8 strings instead of iso8859-1 strings,
+      wherever you see "char *", unless explicitly noted otherwise.
+    - All Tcl strings represented in UTF-8, which is a convenient
+      multi-byte encoding of Unicode.  Variable names, procedure names,
+      and all other values in Tcl may include arbitrary Unicode characters.
+      For example, the Tcl command "string length" returns how many
+      Unicode characters are in the argument string.
+    - For Java compatibility, embedded null bytes in C strings are
+      represented as \xC080 in UTF-8 strings, but the null byte at the end
+      of a UTF-8 string remains \0.  Thus Tcl strings once again do not
+      contain null bytes, except for termination bytes.
+    - For Java compatibility, "\uXXXX" is used in Tcl to enter a Unicode
+      character.  "\u0000" through "\uffff" are acceptable Unicode
+      characters.
+    - "\xXX" is used to enter a small Unicode character (between 0 and 255)
+      in Tcl.
+    - Tcl automatically translates between UTF-8 and the normal encoding for
+      the platform during interactions with the system.
+    - The fconfigure command now supports a -encoding option for specifying
+      the encoding of an open file or socket.  Tcl will automatically
+      translate between the specified encoding and UTF-8 during I/O.
+      See the directory library/encoding to find out what encodings are

+
+9/18/97 (enhancement) Literal objects are now shared by the ByteCode
+structures created when compiled different scripts. This saves up to 45%
+of the total memory needed for all literals. (BL)
+
+9/24/97 (bug fixes) Fixed Tcl_ParseCommand parsing of backslash-newline
+sequences at start of command words. Suppressed Tcl_EvalDirect error logging
+if non-TCL_OK result wasn't an error. (BL)
+
+10/17/97 (feature enhancement) "~username" now refers to the users' home
+directory on Windows (previously always returned failure). (CCS)
+
+10/20/97 (implementation change) The Tcl parser has been completely rewritten
+to make it more modular.  It can now be used to parse a script without actually
+executing it.  The APIs for the new parser are not correctly exported, but
+they will eventually be exported and augmented with Tcl commands so that
+Tcl scripts can parse other Tcl scripts. (JO)
+
+10/21/97 (API change) Added "flags" argument to Tcl_EvalObj, removed
+Tcl_GlobalEvalObj procedure.  Added new procedures Tcl_Eval2 and
+Tcl_EvalObjv. (JO)
+*** POTENTIAL INCOMPATIBILITY ***
+
+10/22/97 (API change) Renamed Tcl_ObjSetVar2 and Tcl_ObjGetVar2 to
+Tcl_SetObjVar2 and Tcl_GetObjVar2 (for consistency with other C APIs)
+and changed the name arguments to be strings instead of objects.  (JO)
+*** POTENTIAL INCOMPATIBILITY ***
+
+10/27/97 (enhancement) Bytecode compiler rewritten to use the new Tcl
+parser. (BL)
+
+11/3/97 (New routines) Added Tcl_AppendObjToObj, which appends the
+string rep of one Tcl_Obj to another. Added Tcl_GetIndexFromObjStruct,
+which is similar to Tcl_GetIndexFromObj, except that you can give an
+offset between strings. This allows Tcl_GetIndexFromObjStruct to be
+called with a table of records which have strings in them. (SRP)
+
+12/4/97 (enhancement) New Tcl expression parser added. Added new procedure
+Tcl_ParseExpr and new token types TCL_TOKEN_SUB_EXPR and
+TCL_TOKEN_OPERATOR. Expression compiler is reimplemented to use this
+parser. (BL)
+
+12/9/97 (bug fix) Tcl_EvalObj() increments/decrements the refcount of the
+script object to prevent the object from deleting itself while in the
+middle of being evaluated. (CCS)
+
+12/9/97 (bug fix) Memory leak in Tcl_GetsObjCmd(). (CCS)
+
+12/11/97 (bug fix) Environment array leaked memory when compiled with
+Visual C++. (SS)
+
+12/11/97 (bug fix) File events and non-blocking I/O did not work on
+pipes under Windows.  Changed to use threads to achieve non-blocking
+behavior. (SS)
+
+12/18/97 (bug fixes) Fixed segfault in "namespace import"; importing a
+procedure that causes a cycle now returns an error. Modified "info procs",
+"info args", "info body", and "info default" to return information about
+imported procedures as well as procedures defined in a namespace. (BL)
+
+12/19/97 (enhancement) Added new Tcl_GetString() procedure that can be used
+in place of Tcl_GetStringFromObj() if the string representation's length
+isn't needed. (BL)
+
+12/18/97 (bug fix) In the opt argument parsing package: if the description
+had only flags, the "too many arguments" case was not detected. The default
+value was not used for the special "args" ending argument. (DL)
+
+1/7/98 (clean up) Moved everything not absolutly necessary out of init.tcl
+procs now in auto.tcl and package.tcl can be autoloaded if needed. (DL)
+
+1/7/98 (enhancement) tcltest made at install time will search for it's
+init.tcl where it is, even when using virtual path compilation. (DL)
+
+1/8/98 (os bug workaround) when needed, using a replacement for memcmp so
+string compare "char with high bit set" "char w/o high bit set" returns
+the expected value on all platforms. (DL)
+
+1/8/98 (unix portability/configure) building from .../unix/targetName/
+subdirectories and simply using "../configure" should now work fine. (DL)
+
+1/14/98 (enhancement) Added new regular expression package that
+supports AREs, EREs, and BREs.  The new package includes new escape
+characters, meta-syntax, and character classes inside brackets.
+Regexps involving backslashes may behave differently.  (MH)
+*** POTENTIAL INCOMPATIBILITY ***
+
+1/16/98 (os workaround) Under windows, "file volume" was causing chatter
+and/or several seconds of hanging when querying empty floppy drives.
+Changed implementation to call an empirically-derived function that doesn't
+cause this. (CCS)
+
+1/16/98 (enhancement) Converted regular expressions to a Tcl_Obj type so
+their compiled form gets cached automatically.  Reduced NSUBEXP from 100
+to 20. (BW)
+
+1/16/98 (documentation) Change unclear documentation and comments for
+functions like Tcl_TranslateFileName() and Tcl_ExternalToUtfDString().  Now
+it explicitly says they take an uninitialized or free DString.  A DString
+that is "empty" or "not holding anything" could have been interpreted as one
+currently with a zero length, but with a large dynamically allocated buffer.
+(CCS)
+
+----------------- Released 8.1a1, 1/22/98 -----------------------
+
+1/28/98 (new feature) Added a "-direct" optional flag to pkg_mkIndex
+to generate direct loading package indexes (such those you need
+if you use namespaces and plan on using namespace import just after
+package require). pkg_mkIndex still has limitations regarding
+package dependencies but errors are now ignored and with -direct, correct
+package indexes can be generated even if there are dependencies as long
+as the "package provide" are done early enough in the files. (DL)
+
+1/28/98 (enhancement) Performance tuning of regexp and regsub. (CCS)
+
+1/28/98 (bug fix) regexp and regsub with "-indices" returned the byte-offsets
+of the characters in the UTF-8 representation, not the character offsets
+themselves. (CCS)
+
+1/28/98 (bug fix) "clock format 0 -format %Z -gmt 1" would return the local
+timezone string instead of "GMT" on Solaris and Windows.
+
+1/28/98 (bug fix) Restore tty settings when closing serial device on Unix.
+This is good behavior when closing real serial devices, essential when
+closing the pseudo-device /dev/tty because the user's terminal settings
+would be left useless, in raw mode, when tcl quit. (CCS)
+
+1/28/98 (bug fix) Tcl_OpenCommandChannel() was modifying the contents of the
+argv array passed to it, causing problems for any caller that wanted to
+continue to use the argv array after calling Tcl_OpenCommandChannel(). (CCS)
+
+2/1/98 (bug fix) More bugs with %Z in format string argument to strftime():
+1. Borland always returned empty string.
+2. MSVC always returned the timezone string for the current time, not the
+   timezone string for the specified time.
+3. With MSVC, "clock format 0 -format %Z -gmt 1" would return "GMT" the first
+   time it was called, but would return the current timezone string on all
+   subsequent calls. (CCS)
+
+2/1/98 (bug fix) "file stat" was broken on Windows.
+1. "file stat" of a root directory (local or network) or a relative path that
+   resolved to a root directory (c:. when in pwd was c:/) was returning error.
+2. "file stat" on a regular file (S_IFREG), the st_mode was sign extended to
+   a negative int if the platform-dependant type "mode_t" was declared as a
+   short instead of an unsigned short.
+3. "file stat" of a network directory, the st_dev was incorrectly reported
+   as the id of the last accessed local drive rather than the id of the
+   network drive. (CCS)
+
+2/1/98 (bug fix) "file attributes" of a relative path that resolved to a
+root directory was returning error. (CCS)
+
+2/1/98 (bug fix) Change error message when "file attribute" could not
+determine the attributes for a file.  Previously it would return different
+error messages on Unix vs.  Windows vs. Mac. (CCS)
+
+2/4/98 (bug fixes) Fixed several instances of bugs where the parser/compiler
+would reach outside the range of allocated memory. Improved the array
+lookup algorithm in set compilation. (DL)
+
+2/5/98 (change) The TCL_PARSE_PART1 flag for Set/Get(Obj)Var2 C APIs is now
+deprecated and ignored. The part1 is always parsed when the part2 argument
+is NULL. This is to avoid a pattern of errors for extension writers converting
+from string based Tcl_SetVar() to new Tcl_SetObjVar2() and who could easily
+forget to provide the flag and thus get code working for normal variables
+but not for array elements. The performance hit is minimal. A side effect
+of that change is that is is no longer possible to create scalar variables
+that can't be accessed by tcl scripts because of their invalid name
+(ending with parenthesis). Likewise it is also parsed and checked to
+ensure that you don't create array elements of array whose name is a valid
+array element because they would not be accessible from scripts anyway.
+Note: There is still duplicate array elements parsing code. (DL)
+*** POTENTIAL INCOMPATIBILITY ***
+
+2/11/98 (bug fix) Sharing objects between interps, such as by "interp
+eval" or "send" could cause a crash later when dereferencing an interp
+that had been deleted, given code such as:
+	set a {set x y}
+	interp create foo
+	interp eval foo $a
+	interp delete foo
+	unset a
+Interp "foo" was gone, but "a" had a internal rep consisting of bytecodes
+containing a dangling pointer to "foo".  Unsetting "a" would attempt to
+return resources back to "foo", causing a crash as random memory was
+accessed.  The lesson is that that if an object's internal rep depends on
+an interp (or any other data structure) it must preserve that data in
+some fashion. (CCS)
+
+2/11/98 (enhancement) The "interp" command was returning inconsistent error
+messages when the specified slave interp could not be found. (CCS)
+
+2/11/98 (bug fix) Result codes like TCL_BREAK and TCL_CONTINUE were not
+propagating through the master/slave interp boundaries, such as "interp
+eval" and "interp alias".  TCL_OK, TCL_ERROR, and non-standard codes like
+teh integer 57 work.  There is still a question as to whether TCL_RETURN
+can/should propagate. (CCS)
+
+2/11/98 (bug fix) TclCompileScript() was derefering memory 1 byte before
+start of the string to compile, looking for ']'. (CCS,DL)
+
+2/11/98 (bug fix) Tcl_Eval2() was derefering memory 1 byte before start
+of the string to eval, looking for ']'. (CCS,DL)
+
+2/11/98 (bug fix) Compiling "set a(b" was running off end of string. (CCS,DL)
+
+2/11/98 (bug fix) Windows initialization code was dereferencing
+uninitialized memory if TCL_LIBRARY environment didn't exist. (CCS)
+
+2/11/98 (bug fix) Windows "registry" command was dereferencing
+uninitialized memory when constructing the $errorCode for a failed
+registry call. (CCS)
+
+2/11/98 (enhancement) Eliminate the TCL_USE_TIMEZONE_VAR definition from
+configure.in, because it was the same information as the already existing
+HAVE_TM_ZONE definition.  The lack of HAVE_TM_ZONE is used to work around a
+Solaris and Windows bug where "clock format [clock sec] -format %Z -gmt 1"
+produces the local timezone string instead of "GMT". (CCS)
+
+2/11/98 (bug fix) Memleaks and dereferencing of uninitialized memory in
+regexp if an error occurred while compiling a regular expression. (CCS).
+
+2/18/98 (new feature) Added mutexes and thread local storage in order
+to make Tcl thread safe.  For testing purposes, there is a testthread
+command that creates a new thread and an interpreter inside it.  See
+thread.test for examples, but this script-level interface is not fixed.
+Each thread has its own notifier instance to manage its own events,
+and threads can post messages to each other's message queue.
+This uses pthreads on UNIX, and native thread support on other platforms.
+You enable this by configuring with --enable-threads.  Note that at
+this time *Tk* is still not thread safe. Special thanks to
+Richard Hipp: his earlier implementation inspired this work. (BW, SS, JI)
+
+2/18/98 (hidden feature change) The way the env() array is shared among
+interpreters changed.  Updates to env used to trigger write traces in
+other interpreters.  This undocumented feature is no longer implemented.
+Instead, variable tracing is used to keep the C-level environ array in sync
+with the Tcl-level env array. This required adding TCL_TRACE_ARRAY support
+to Tcl_TraceVar2 so that array names works properly. (BW)
+*** POTENTIAL INCOMPATIBILITY ***
+
+2/18/98 (enhancement) Conditional compilation for unix systems (e.g.,
+IRIX, SCO) that use f_bsize instead of st_blksize to determine disk block
+size. (CCS)
+
+2/23/98 (bug fix) Fixed the emulation of polling selects in the threaded
+version of the Unix notifier.  The bug was showing up on a multiprocessor
+as starvation of the notifier thread. (BW)
+
+----------------- Released 8.1a2, Feb 23 1998 -----------------------
+
+9/22/98 (bug fix) Changed the value of TCL_TRACE_ARRAY so it no longer
+conflicts with the deprecated TCL_PARSE_PART1 flag.  This should
+improve portability of C code. (stanton)
+
+10/6/98 (bug fix) The compile procedure for "if" incorrectly attempted
+to match against the literal string "if", resulting in a stack
+overflow when "::if" was compiled.  It also would incorrectly accept
+"if" instead of "elsif" in later clauses.  (stanton)
+
+10/15/98 (new feature) Added a "totitle" subcommand to the "string"
+command to convert strings to capitalize the first character of a string
+and lowercase all of the other characters. (stanton)
+
+10/15/98 (bug fix) Changed regexp and string commands to properly
+handle case folding according to the Unicode character
+tables. (stanton)
+
+10/21/98 (new feature) Added an "encoding" command to facilitate
+translations of strings between different character encodings.  See
+the encoding.n manual entry for more details. (stanton)
+
+11/3/98 (bug fix) The regular expression character classification
+syntax now includes Unicode characters in the supported
+classes. (stanton)
+
+11/6/98 (bug fix) Variable traces were causing crashes when upvar
+variables went out of scope. [Bug: 796] (stanton)
+
+11/9/98 (bug fix) "format" now correctly handles multibyte characters
+in %s format strings. (stanton)
+
+11/10/98 (new feature) "regexp" now accepts three new switches
+("-line", "-lineanchor", and "-linestop") that control how regular

+details. (stanton)
+
+11/17/98 (bug fix) "scan" now correctly handles Unicode

+
+11/17/98 (new feature) "scan" now supports XPG3 position specifiers
+and the "%n" conversion character.  See the "scan" manual entry for
+more details. (stanton)
+
+11/17/98 (bug fix) The Tcl memory allocator now returns 8-byte aligned
+chunks of memory which improves performance on Windows and avoids
+crashes on other platforms. [Bug: 834] (stanton)
+
+11/23/98 (bug fix) Applied various regular expression performance bug
+fixes supplied by Henry Spencer. (stanton)
+
+11/30/98 (bug fix) Fixed various thread related race conditions. [Bug:
+880 & 607] (stanton)
+
+11/30/98 (bug fix) Fixed a number of memory overflow and leak
+bugs. [Bug: 584] (stanton)
+
+12/1/98 (new feaure) Added support for Korean encodings. (stanton)
+
+12/1/98 (feature change) Changed the Tcl_EvalObjv interface to remove
+the string and length arguments.
+*** POTENTIAL INCOMPATIBILITY with previous alpha releases ***
+
+12/2/98 (bug fix) Fixed various bugs related to line feed
+translation. [Bug: 887] (stanton)

+12/4/98 (new feature) Added a message catalog facility to help with
+localizing Tcl scripts.  Thanks to Mark Harrison for contributing the
+initial implementation of the "msgcat" package. (stanton)

+performance (about 5x speed up).  Thanks to Syd Polk for suppling the
+patch. [RFE: 726] (rjohnson)
+
+2/10/99 (bug fix) Restored the Tcl_ObjSetVar2/Tcl_ObjGetVar2
+interfaces from 8.0 and renamed the Tcl_GetObjVar2/Tcl_SetObjVar2
+interfaces to Tcl_GetVar2Ex and Tcl_SetVar2Ex.  This should provide

+that affected HP-UX-11, 64-bit IRIX, Linux, and Solaris. (stanton)
+
+3/9/99 (bug fix) Integrated various AIX related patches to improve
+support for shared libraries. (stanton)
+
+3/9/99 (new feature) Added tcl_platform(user) to provide a portable
+way to get the name of the current user. (welch)
+
+3/9/99 (new feature) Integrated the stub library mechanism contributed
+by Jan Nijtmans, Paul Duffin, and Jean-Claude Wippler.  This feature
+should make it possible to write extensions that support multiple
+versions of Tcl simultaneously.  It also makes it possible to
+dynamically load extensions into statically linked interpreters.  This
+patch includes the following changes:
+      -	Added a Tcl_InitStubs() interface
+      -	Added Tcl_PkgProvideEx, Tcl_PkgRequireEx, Tcl_PkgPresentEx,

+
+3/10/99 (new feature) Added a Tcl_GetVersion API to make it easier to
+check the Tcl version and patch level from C. (redman)
+
+3/14/99 (feature change) Tried to unify the TclpInitLibrary path
+routines to look in similar places from Windows to UNIX.  The new
+library search path is: TCL_LIBRARY, TCL_LIBRARY/../tcl8.1, relative
+to DLL (Windows Only) relative to installed executable, relative to
+develop executable, and relative to compiled-in in location (UNIX
+Only.)  This fix included:
+    - Defining a TclpFindExecutable
+    - Moving Tcl_FindExecutable to a common area in tclEncoding.c
+    - Modifying the TclpInitLibraryPath routines.
+(surles)
+
+3/14/99 (feature change) Added hooks for TclPro Wrapper to initialize

+      pre-init script.
+    - Adding the Tcl_SetdefaultEncodingDir and Tcl_GetDefaultEncodingDir
+      routines.
+    - Modifying the TclpInitLibrary routines to append the default

+(surles)
+
+3/14/99 (feature change) Test suite now uses "test" namespace to
+define the test procedure and other auxiliary procedures as well as
+global variables.
+    - Global array testConfige is now called ::test::testConfig.
+    - Global variable VERBOSE is now called ::test::verbose, and
+      ::test::verbose no longer works with numerical values.  We've
+      switched to a bitwise character string.  You can set
+      ::test::verbose by using the -verbose option on the Tcl command
+      line.
+    - Global variable TESTS is now called ::test::matchingTests, and
+      can be set on the Tcl command line via the -match option.
+    - There is now a ::test::skipTests variable (works similarly to
+      ::test::matchTests) that can be set on the Tcl command line via
+      the -match option.
+    - The test suite can now be run in any working directory.  When

+4/9/99 (bug fix)  Fixed notifier deadlock situation when the pipe used
+to talk back notifier thread is filled with data.  Found as a result of the
+focus.test for Tk hanging. (redman)
+
+4/13/99 (bug fix) Fixed bug where socket -async combined with
+fileevent for writing did not work under Windows NT. (redman)
+
+4/13/99 (encoding fix) Restored the double byte definition of GB2312
+and added the EUC-CN encoding.  EUC-CN is a variant of GB2312 that
+shifts the characters into bytes with the high bit set and includes
+ASCII as a subset. (stanton)
+
+4/27/99 (bug fix) Added 'extern "C" {}' block around the stub table
+pointer declaration so the stub library can be used from C++. (stanton)
+
+--------------- Released 8.1 final, April 29, 1999 ----------------------
+
+4/22/99 (bug fix) Changed Windows NT socket implementation to avoid
+creating a communication window.  This avoids the problem where the
+system hangs waiting for tclsh to respond to a system-wide synchronous
+broadcast (e.g. if you change system colors). (redman)
+
+4/22/99 (bug fix) Added call to TclWinInit from TclpInitPlatform when
+building a static library since DllMain will not be invoked.  This
+could break old code that explicitly called TclWinInit, but should be
+simpler in the long run. (stanton)
+*** POTENTIAL INCOMPATIBILITY ***
+
+4/23/99 (bug fix) Added support for the koi8-r Cyrillic
+encoding. [Bug: 1771] (stanton)
+
+4/28/99 (bug fix) Changed internal Tcl_Obj usage to avoid freeing the
+internal representation after the string representation has been
+freed.  This makes it easier to debug extensions. (stanton)
+
+4/30/99 (bug fix) Fixed a memory leak in CommandComplete. (stanton)
+
+5/3/99 (bug fix) Fixed a bug where the Tcl_ObjType was not being set
+in a duplicated Tcl_Obj. [Bug: 1975, 2047] (stanton)
+
+5/3/99 (bug fix) Changed Tcl_ParseCommand to avoid modifying eval'ed
+strings that are already null terminated.  [Bug: 1793] (stanton)
+
+5/3/99 (new feature) Applied Jeff Hobbs's string patch which includes
+the following changes:
+    - added new subcommands: equal, repeat, map, is, replace
+    - added -length option to "string compare|equal"
+    - added -nocase option to "string compare|equal|match"
+    - string and list indices can be an integer or end?-integer?.
+    - added optional first and last index args to string toupper, et al.
+See the string.n manual entry for more details about the new string
+features.  [Bug: 1845] (stanton)
+
+5/6/99 (new feature) Added Tcl_UtfNcmp and Tcl_UtfNcasecmp to make Utf
+string comparision easier. (stanton)
+
+5/7/99 (bug fix) Improved OS/390 support. [Bug: 1976, 1997] (stanton)
+
+5/12/99 (bug fix) Changed Windows initialization code to avoid using
+GetUserName system call in favor of the env(USERNAME) variable.  This
+provides a significant startup speed improvement. (stanton)
+
+5/12/99 (bug fix) Replaced the per-interpreter regexp cache with a
+per-thread cache.  Changed the Regexp object to take advantage of this
+extra cache.  Added a reference count to the TclRegexp type so regexps
+can be shared by multiple objects.  Removed the per-interp regexp cache
+from the interpreter.  Now regexps can be used with no need for an
+interpreter. This set of changes should provide significant speed
+improvements for many Tcl scripts.  [Bug: 1063] (stanton)
+
+5/14/99 (bug fix) Durining initialization on Unix, Tcl now extracts the
+encoding subfield from the LANG/LC_ALL environment variables in cases
+where the locale is not found in the built-in locale table.  It also
+attempts to initialize the locale subsystem so X11 is happy. [Bug: 1989]
+(stanton)
+
+5/14/99 (bug fix) Applied the patch to fix 100-year and 400-year
+boundaries in leap year code, from Isaac Hollander.  [Bug: 2066] (redman)
+
+5/14/99 (bug fix) Fixed a crash caused by a failure to reset the result
+before evaluating the test expression in an uncompiled for
+statement. (stanton)
+
+5/18/99 (bug fix) Modified initialization code on Windows to avoid
+inherenting closed or invalid channels.  If the standard input is
+anything other than a console, file, serial port, or pipe, then we fall
+back to the standard Tk window console. (stanton)
+
+5/19/99 (bug fix) Added an extern "C" block around the entire tcl.h
+header file to avoid C++ linkage issues. (redman)
+
+5/19/99 (new feature) Applied Jeff Hobb's patch to add
+Tcl_StringCaseMatch to support case insensitive glob style matching and
+Tcl_UniCharIs* character classification functions. (stanton)
+
+5/20/99 (bug fix) Added the directory containing the executuble and the
+../lib directory relative to that to the auto_path variable. (redman)
+
+--------------- Released 8.1.1, May 25, 1999 ----------------------
+
+5/21/99 (bug fix) Fixed launching command.com on Win95/98, no longer
+hangs. [Bug: 2105] (redman)
+
+5/28/99 (bug fix) Fixed bug where dde calls were being passed an
+invalid dde handle. [Bug: 2124] (stanton)
+
+6/1/99  (bug fix) Small configure.in patches. [Bug: 2121] (stanton)
+
+6/1/99  (bug fix) Applied latest regular expression patches to fix an
+infinite loop bug and add support for testing whether a string could
+match with additional input. [Bug: 2117] (stanton)
+
+6/2/99  (bug fix) Fixed incorrect computation of relative ordering in
+Utf case-insensitive comparison. [Bug: 2135] (stanton)
+
+6/3/99  (bug fix) Fxied bug where string equal/compare -nocase
+reported wrong result on null strings. [Bug: 2138] (stanton)
+
+6/4/99  (new feature) Windows build now uses Cygwin tools plus GNU
+make and autoconf to build static/dynamic and debug/nodebug. (stanton)
+
+6/7/99  (new feature) Optimized string index, length, range, and
+append commands. Added a new Unicode object type. (hershey)
+
+6/8/99  (bug fix) Rolled back Windows socket driver to 8.1.0
+version. (stanton)
+
+6/9/99  (new feature) Added Tcl_RegExpMatchObj and Tcl_RegExpGetInfo
+to public Tcl API, these functions are needed by Expect.  Changed
+tools/genStubs.tcl to always write output in LF mode. (stanton)
+
+6/14/99 (new feature) Merged string and Unicode object types.  Added
+new public Tcl API functions:  Tcl_NewUnicodeObj, Tcl_SetUnicodeObj,
+Tcl_GetUnicode, Tcl_GetUniChar, Tcl_GetCharLength, Tcl_GetRange,
+Tcl_AppendUnicodeToObj. (hershey)
+
+6/16/99 (new feature) Changed to conform to TEA specification, added
+tcl.m4 and aclocal.m4 macro libraries for configure.  (wart)
+
+6/17/99 (new feature) Added new regexp interfaces: -expanded, -line,
+-linestop, and -lineanchor switches.  Renamed Tcl_RegExpMatchObj to
+Tcl_RegExpExecObj and added new Tcl_RegExpMatchObj that is equivalent
+to Tcl_RegExpMatch.  Added public macros for regexp flags.  Added
+REG_BOSONLY flag to allow Expect to iterate through a string and only
+find matches that start at the current position within the
+string. (stanton)
+
+6/21/99 (bug fix) Fixed memory leak in TclpThreadCreate where thread
+attributes were not being released.  [Bug: 2254] (stanton)
+
+6/23/99 (new feature) Updated Unicode character tables to reflect
+Unicode 2.1 data. (stanton)
+
+6/25/99 (new feature) Fixed bugs in non-greedy quantifiers for regular
+expression code. (stanton)
+
+6/25/99 (new feature) Added initial implementation of new Tcl test
+harness package.  Modified test files to use new tcltest package.
+(jenn)
+
+6/26/99 (new feature) Applied patch from Peter Hardie to add poke
+command to dde and changed the dde package version number to

+-limitconstraints, -help, -file, -notfile, and flags.  (jenn)
+
+7/3/99  (new feature) Changed parsing of variable names to allow empty
+array names.  Now "$(foo)" is a variable reference.  Previously you
+had to use something line $::(foo), which is slower.  This change was
+requested by Jean-Luc Fontaine for his STOOOP package. (welch)
+
+7/3/99  (new feature) Added Tcl_SetNotifier (public API) and
+associated hook points in the notifiers to be able to replace the
+notifier calls at runtime. The Xt notifier and test program use this
+hook.  (welch)
+
+7/3/99  (new feature) Added a new variant of the "Trf core patch" from
+Andreas Kupries that adds new C APIs Tcl_StackChannel,
+Tcl_UnstackChannel, and Tcl_GetStackedChannel.  This allows the Trf
+extension to work without applying patches to the Tcl core. (welch)
+
+7/6/99  (new feature) Added -timeout option to http.tcl to handle
+timeouts that occur during connection attempts to hosts that are
+down. (welch)
+
+7/6/99  (bug fix) Applied new implementation of the Windows serial
+port driver from Rolf Schroedter that fixes reading only one byte from
+the port at a time.  Uses polling every 10ms to implement
+fileevents. [Bug: 1980 2217] (redman)

+also fixed a bug that caused TCL_LIBRARY to be ignored. (hershey)
+
+7/21/99 (bug fix) Implemented modified socket driver for Windows that
+uses a thread to manage the socket event window.  Code works the same
+on all supported versions of Windows and was based on original 8.1.0
+code.  [Bug: 2178 2256 2259 2329 2323 2355] (redman)
+
+7/21/99 (new feature) Applied patch from Rolf Schroedter to add
+-pollinterval option to fconfigure for Windows serial ports.  Allows

+checked for fileevents.  Also added documentation for \\.\comX
+notation for opening serial ports on Windows.  (redman)
+
+7/21/99 (bug fix) Changed APIs in stub tables to use "unsigned long"
+instead of the platform-specific "size_t", primarily after SunOS 4
+users could no longer compile. (redman)
+
+7/22/99 (bug fix) Fixed crashing during "array set a(b) {}".
+[Bug: 2427] (redman)

+threads enabled. (redman)
+
+7/26/99 (bug fix) Fixed terminating of helper threads by holding any
+mutexes from the primary thread while waiting for the helper thread to
+terminate.  Fixes dual-CPU WinNT hangs, only one rare sporadic hang
+that still exists with dual-CPU WinNT.  Also fixed test cases so that
+they would not depend as much on timing for dual-CPU WinNT. (redman)
+
+7/27/99 (bug fix) Some test suite cleanup. (jenn)
+
+7/29/99 (bug fix) Applied patch to fix typo in .SH NAME line in

+
+8/9/99 (internal api change) Removed the TclpMutexLock and TclpMutexUnlock
+APIs and added a new exported api, Tcl_GetAllocMutex. These APIs are all for
+the mutex used in the simple memory allocators.  By making this change
+we are able to substitute different implementations of the thread-related
+APIs without having to recompile the Tcl core. (welch)
+
+8/9/99 (new C API) Tcl_GetChannelNames returns a list of open channel
+names in the interpreter result.  Still no Tcl-level version of this,
+but server-like applications can use this to clean up files without
+deleting interpreters. (welch)
+
+8/9/99 (bug fix) Traces were not firing on "info exists", which used to
+happen in Tcl 7.6 and earlier. An "info exists" now fires a read trace,

+10/30/99 (bug fix) removed savedChar trick in tclCompile.c that appeared
+to be causing a segv when the literal table was released.
+[Bug: 2459, 2515] (David Whitehouse)

+atexit handlers.
+
+12/07/99 (bug fix) fixes for 'expr + {[incr]}' and 'expr + {[error]}'

+
+--- Released 8.4.6, March 1, 2004 --- See ChangeLog for details ---
+
+Changes to 8.5a1 include all changes to the 8.4 line through 8.4.6,
+plus the following, which focuses on the high-level feature changes
+in this changeset (new minor version) rather than bug fixes:
+
+ * refactored IO code to split FS path code into generic/tclPathObj.c
+  and generic/tclFileSystem.h
+
+ * refactored trace code into generic/tclTrace.c
+
+ * configure scripts now require autoconf 2.57 for regeneration
+
+ * updated runtime library scripts to use newer Tcl code features
+   (like replacing regsub with string map)
+
+ * improve robustness of tcltest test suite across environments
+
+ * changed the bytecode evaluation-stack addressing mode, from array-style
+   to pointer-style; the catch stack and evaluation stack are now
+   contiguous in memory
+
+ * switch command is now byte-compiled
+
+ * enhanced checking in 'file' command for Windows NT file permissions
+
+ * [TIP #57] new 'lassign' command (adopted from TclX)
+
+ * [TIP #75] switch -regexp now provides submatch info
+
+ * [TIP #90] extended 'catch' and 'return' to enable creation of procs
+   that are a true replacement for 'return'
+
+ * [TIP #100] new 'unload' command (can unload DLLs loaded via 'load',
+   requires the extension writer to support it)
+
+ * [TIP #111] new 'dict' command.  Several commands have been updated
+   to handle the list form of dicts implicitly at the C level where
+   only lists were previously accepted
+
+ * [TIP #112] 'namespace ensemble' command addition allows for ensembles
+   that build on the namespace abstraction
+
+ * [TIP #118] file attributes -readonly option for unices that support
+   chflags(), support Mac Classic attribute options on OS X, add
+   -rsrclength for OS X, enhance file copy on OS X to copy finder
+   attributes and resource forks transparently
+
+ * [TIP #120] enable dde in safe interpreters
+ * [TIP #130] enable unique dde server names on Windows
+ * [TIP #135] change dde servername -exact option to -force
+=> dde 1.3
+
+ * [TIP #121] new Tcl_SetExitProc C API to control application shutdown
+
+ * [TIP #123] expr ** exponentiation operator
+
+ * [TIP #124] 'clock clicks -milliseconds' now returns a wide integer and a
+   new 'clock clicks -microseconds' returns a wide integer, representing
+   the number of microseconds, both since the Posix epoch
+
+ * [TIP #127] added 'lsearch -index' option
+
+ * [TIP #136] added 'lrepeat' command
+
+ * [TIP #137/151] Add -encoding option to 'source' command and main tclsh
+   executable.
+     *** POTENTIAL INCOMPATIBILITY ***
+   For Tcl embedders that build on Tcl_Main() and make use of Tcl_Main's
+   former ability to pass a leading "-encoding" option to interactive shell
+   operations, this will now be consumed by Tcl.
+
+ * [TIP #138] New TCL_HASH_KEY_SYSTEM_HASH option for Tcl hash tables
+
+ * [TIP #139] documented portions of Tcl's namespace C APIs
+
+ * [TIP #148] correct [list]-quoting of the '#' character
+     *** POTENTIAL INCOMPATIBILITY ***
+   For scripts that assume a particular (buggy) string rep for lists.
+
+ * [TIP #156] add "root locale" to msgcat
+=> msgcat 1.4
+
+ * [TIP #157] leading {expand} syntax on words to cause argument expansion.
+   This is a safer/cleaner alternative to the use of 'eval'.

+\fBF_OK\fR. \fBR_OK\fR, \fBW_OK\fR and \fBX_OK\fR request checking whether the
+file exists and has read, write and execute permissions, respectively.
+\fBF_OK\fR just requests a check for the existence of the file.
+.AP "struct stat" *statPtr out
+The structure that contains the result.
+.BE
+.SH DESCRIPTION
+.PP
+As of Tcl 8.4, the object-based APIs \fBTcl_FSAccess\fR and \fBTcl_FSStat\fR
+should be used in preference to \fBTcl_Access\fR and \fBTcl_Stat\fR, wherever
+possible. Those functions also support Tcl's virtual filesystem layer, which
+these do not.
+.SS "OBSOLETE FUNCTIONS"
+.PP
+There are two reasons for calling \fBTcl_Access\fR and \fBTcl_Stat\fR rather
+than calling system level functions \fBaccess\fR and \fBstat\fR directly.
+First, the Windows implementation of both functions fixes some bugs in the
+system level calls. Second, both \fBTcl_Access\fR and \fBTcl_Stat\fR (as well
+as \fBTcl_OpenFileChannelProc\fR) hook into a linked list of functions. This
+allows the possibility to reroute file access to alternative media or access
+methods.
+.PP
+\fBTcl_Access\fR checks whether the process would be allowed to read, write or
+test for existence of the file (or other file system object) whose name is
+\fIpath\fR. If \fIpath\fR is a symbolic link on Unix, then permissions of the
+file referred by this symbolic link are tested.
+.PP
+On success (all requested permissions granted), zero is returned. On error (at
+least one bit in mode asked for a permission that is denied, or some other
+error occurred), -1 is returned.
+.PP
+\fBTcl_Stat\fR fills the stat structure \fIstatPtr\fR with information about
+the specified file. You do not need any access rights to the file to get this
+information but you need search rights to all directories named in the path
+leading to the file. The stat structure includes info regarding device, inode
+(always 0 on Windows), privilege mode, nlink (always 1 on Windows), user id
+(always 0 on Windows), group id (always 0 on Windows), rdev (same as device on
+Windows), size, last access time, last modification time, and creation time.
+.PP
+If \fIpath\fR exists, \fBTcl_Stat\fR returns 0 and the stat structure is
+filled with data. Otherwise, -1 is returned, and no stat info is given.

+.SH DESCRIPTION
+.PP
+The \fBTcl_SetReturnOptions\fR and \fBTcl_GetReturnOptions\fR
+routines expose the same capabilities as the \fBreturn\fR and
+\fBcatch\fR commands, respectively, in the form of a C interface.
+.PP
+\fBTcl_GetReturnOptions\fR retrieves the dictionary of return options
+from an interpreter following a script evaluation.
+Routines such as \fBTcl_Eval\fR are called to evaluate a
+script in an interpreter.  These routines return an integer
+completion code.  These routines also leave in the interpreter
+both a result and a dictionary of return options generated
+by script evaluation.  Just as \fBTcl_GetObjResult\fR retrieves
+the result, \fBTcl_GetReturnOptions\fR retrieves the dictionary
+of return options.  The integer completion code should be
+passed as the \fIcode\fR argument to \fBTcl_GetReturnOptions\fR
+so that all required options will be present in the dictionary.
+Specifically, a \fIcode\fR value of \fBTCL_ERROR\fR will
+ensure that entries for the keys \fB\-errorinfo\fR,
+\fB\-errorcode\fR, and \fB\-errorline\fR will appear in the
+dictionary.  Also, the entries for the keys \fB\-code\fR
+and \fB\-level\fR will be adjusted if necessary to agree
+with the value of \fIcode\fR.  The \fB(Tcl_Obj *)\fR returned
+by \fBTcl_GetReturnOptions\fR points to an unshared
+\fBTcl_Obj\fR with reference count of zero.  The dictionary
+may be written to, either adding, removing, or overwriting
+any entries in it, without the need to check for a shared value.
+As with any \fBTcl_Obj\fR with reference count of zero, it is up to
+the caller to arrange for its disposal with \fBTcl_DecrRefCount\fR or
+to a reference to it via \fBTcl_IncrRefCount\fR (or one of the many
+functions that call that, notably including \fBTcl_SetObjResult\fR and
+\fBTcl_SetVar2Ex\fR).
+.PP
+A typical usage for \fBTcl_GetReturnOptions\fR is to
+retrieve the stack trace when script evaluation returns
+\fBTCL_ERROR\fR, like so:
+.PP
+.CS
+int code = Tcl_Eval(interp, script);
+if (code == TCL_ERROR) {
+    Tcl_Obj *options = \fBTcl_GetReturnOptions\fR(interp, code);  
+    Tcl_Obj *key = Tcl_NewStringObj("-errorinfo", -1);
+    Tcl_Obj *stackTrace;
+    Tcl_IncrRefCount(key);
+    Tcl_DictObjGet(NULL, options, key, &stackTrace);
+    Tcl_DecrRefCount(key);
+    /* Do something with stackTrace */
+    Tcl_DecrRefCount(options);
+}
+.CE
+.PP
+\fBTcl_SetReturnOptions\fR sets the return options
+of \fIinterp\fR to be \fIoptions\fR.  If \fIoptions\fR
+contains any invalid value for any key, TCL_ERROR will
+be returned, and the interp result will be set to an
+appropriate error message.  Otherwise, a completion code
+in agreement with the \fB\-code\fR and \fB\-level\fR
+keys in \fIoptions\fR will be returned.
+.PP
+As an example, Tcl's \fBreturn\fR command itself could
+be implemented in terms of \fBTcl_SetReturnOptions\fR
+like so:
+.PP
+.CS
+if ((objc % 2) == 0) { /* explicit result argument */
+    objc--;
+    Tcl_SetObjResult(interp, objv[objc]);
+}
+return \fBTcl_SetReturnOptions\fR(interp, Tcl_NewListObj(objc-1, objv+1));
+.CE
+.PP
+(It is not really implemented that way.  Internal access
+privileges allow for a more efficient alternative that meshes
+better with the bytecode compiler.)
+.PP
+Note that a newly created \fBTcl_Obj\fR may be passed
+in as the \fIoptions\fR argument without the need to tend
+to any reference counting.  This is analogous to
+\fBTcl_SetObjResult\fR.
+.PP
+While \fBTcl_SetReturnOptions\fR provides a general interface
+to set any collection of return options, there are a handful
+of return options that are very frequently used.  Most 
+notably the \fB\-errorinfo\fR and \fB\-errorcode\fR return
+options should be set properly when the command procedure
+of a command returns \fBTCL_ERROR\fR.  The \fB\-errorline\fR
+return option is also read by commands that evaluate scripts
+and wish to supply detailed error location information in 
+the stack trace text they append to the \fB\-errorinfo\fR option.
+Tcl provides several simpler interfaces to more directly set
+these return options.
+.PP
+The \fB\-errorinfo\fR option holds a stack trace of the
+operations that were in progress when an error occurred,
+and is intended to be human-readable.
+The \fB\-errorcode\fR option holds a list of items that
+are intended to be machine-readable.
+The first item in the \fB\-errorcode\fR value identifies the class of
+error that occurred
+(e.g. POSIX means an error occurred in a POSIX system call)
+and additional elements hold additional pieces
+of information that depend on the class.
+See the \fBtclvars\fR manual entry for details on the various
+formats for the \fB\-errorcode\fR option used by
+Tcl's built-in commands.
+.PP
+The \fB\-errorinfo\fR option value is gradually built up as an
+error unwinds through the nested operations.
+Each time an error code is returned to \fBTcl_Eval\fR, or
+any of the routines that performs script evaluation,
+the procedure \fBTcl_AddErrorInfo\fR is called to add
+additional text to the \fB\-errorinfo\fR value describing the
+command that was being executed when the error occurred.
+By the time the error has been passed all the way back
+to the application, it will contain a complete trace
+of the activity in progress when the error occurred.
+.PP
+It is sometimes useful to add additional information to
+the \fB\-errorinfo\fR value beyond what can be supplied automatically
+by the script evaluation routines.
+\fBTcl_AddErrorInfo\fR may be used for this purpose:
+its \fImessage\fR argument is an additional
+string to be appended to the \fB\-errorinfo\fR option.
+For example, when an error arises during the \fBsource\fR command,
+the procedure \fBTcl_AddErrorInfo\fR is called to
+record the name of the file being processed and the
+line number on which the error occurred.
+Likewise, when an error arises during evaluation of a
+Tcl procedures, the procedure name and line number
+within the procedure are recorded, and so on.
+The best time to call \fBTcl_AddErrorInfo\fR is just after
+a script evaluation routine has returned \fBTCL_ERROR\fR.
+The value of the \fB\-errorline\fR return option (retrieved
+via a call to \fBTcl_GetReturnOptions\fR) often makes up
+a useful part of the \fImessage\fR passed to \fBTcl_AddErrorInfo\fR.
+.PP
+\fBTcl_AppendObjToErrorInfo\fR is an alternative interface to the
+same functionality as \fBTcl_AddErrorInfo\fR.  \fBTcl_AppendObjToErrorInfo\fR
+is called when the string value to be appended to the \fB\-errorinfo\fR option
+is available as a \fBTcl_Obj\fR instead of as a \fBchar\fR array.
+.PP
+\fBTcl_AddObjErrorInfo\fR is nearly identical
+to \fBTcl_AddErrorInfo\fR, except that it has an additional \fIlength\fR
+argument.  This allows the \fImessage\fR string to contain 
+embedded null bytes.  This is essentially never a good idea.
+If the \fImessage\fR needs to contain the null character \fBU+0000\fR,
+Tcl's usual internal encoding rules should be used to avoid
+the need for a null byte.  If the \fBTcl_AddObjErrorInfo\fR
+interface is used at all, it should be with a negative \fIlength\fR value.
+.PP
+The procedure \fBTcl_SetObjErrorCode\fR is used to set the
+\fB\-errorcode\fR return option to the list value \fIerrorObjPtr\fR 
+built up by the caller. 
+\fBTcl_SetObjErrorCode\fR is typically invoked just 
+before returning an error. If an error is
+returned without calling \fBTcl_SetObjErrorCode\fR or
+\fBTcl_SetErrorCode\fR the Tcl interpreter automatically sets
+the \fB\-errorcode\fR return option to \fBNONE\fR.
+.PP
+The procedure \fBTcl_SetErrorCode\fR is also used to set the
+\fB\-errorcode\fR return option. However, it takes one or more strings to
+record instead of a value. Otherwise, it is similar to
+\fBTcl_SetObjErrorCode\fR in behavior.
+.PP
+\fBTcl_SetErrorCodeVA\fR is the same as \fBTcl_SetErrorCode\fR except that
+instead of taking a variable number of arguments it takes an argument list.
+.PP
+The procedure \fBTcl_GetErrorLine\fR is used to read the integer value
+of the \fB\-errorline\fR return option without the overhead of a full
+call to \fBTcl_GetReturnOptions\fR.  Likewise, \fBTcl_SetErrorLine\fR
+sets the \fB\-errorline\fR return option value.
+.PP
+\fBTcl_PosixError\fR
+sets the \fB\-errorcode\fR variable after an error in a POSIX kernel call.
+It reads the value of the \fBerrno\fR C variable and calls
+\fBTcl_SetErrorCode\fR to set the \fB\-errorcode\fR return
+option in the \fBPOSIX\fR format.
+The caller must previously have called \fBTcl_SetErrno\fR to set
+\fBerrno\fR; this is necessary on some platforms (e.g. Windows) where Tcl
+is linked into an application as a shared library, or when the error
+occurs in a dynamically loaded extension. See the manual entry for
+\fBTcl_SetErrno\fR for more information.
+.PP
+\fBTcl_PosixError\fR returns a human-readable diagnostic message
+for the error
+(this is the same value that will appear as the third element
+in the \fB\-errorcode\fR value).
+It may be convenient to include this string as part of the
+error message returned to the application in
+the interpreter's result.
+.PP
+\fBTcl_LogCommandInfo\fR is invoked after an error occurs in an
+interpreter.  It adds information about the command that was being
+executed when the error occurred to the \fB\-errorinfo\fR value, and
+the line number stored internally in the interpreter is set.  
+.PP
+In older releases of Tcl, there was no \fBTcl_GetReturnOptions\fR
+routine.  In its place, the global Tcl variables \fBerrorInfo\fR
+and \fBerrorCode\fR were the only place to retrieve the error
+information.  Much existing code written for older Tcl releases
+still access this information via those global variables.
+.PP
+It is important to realize that while reading from those
+global variables remains a supported way to access these
+return option values, it is important not to assume that
+writing to those global variables will properly set the
+corresponding return options.  It has long been emphasized
+in this manual page that it is important to 
+call the procedures described here rather than
+setting \fBerrorInfo\fR or \fBerrorCode\fR directly with
+\fBTcl_ObjSetVar2\fR.
+.PP
+If the procedure \fBTcl_ResetResult\fR is called,
+it clears all of the state of the interpreter associated with
+script evaluation, including the entire return options dictionary.
+In particular, the \fB\-errorinfo\fR and \fB\-errorcode\fR options
+are reset.  
+If an error had occurred, the \fBTcl_ResetResult\fR call will
+clear the error state to make it appear as if no error had
+occurred after all.
+The global variables \fBerrorInfo\fR and
+\fBerrorCode\fR are not modified by \fBTcl_ResetResult\fR
+so they continue to hold a record of information about the
+most recent error seen in an interpreter.

+.SH DESCRIPTION
+.PP
+These procedures provide a platform and compiler independent interface
+for memory allocation.  Programs that need to transfer ownership of
+memory blocks between Tcl and other modules should use these routines
+rather than the native \fBmalloc()\fR and \fBfree()\fR routines
+provided by the C run-time library.
+.PP
+\fBTcl_Alloc\fR returns a pointer to a block of at least \fIsize\fR
+bytes suitably aligned for any use.
+.PP
+\fBTcl_Free\fR makes the space referred to by \fIptr\fR available for
+further allocation.
+.PP
+\fBTcl_Realloc\fR changes the size of the block pointed to by
+\fIptr\fR to \fIsize\fR bytes and returns a pointer to the new block.
+The contents will be unchanged up to the lesser of the new and old
+sizes.  The returned location may be different from \fIptr\fR.  If
+\fIptr\fR is NULL, this is equivalent to calling \fBTcl_Alloc\fR with
+just the \fIsize\fR argument.
+.PP
+\fBTcl_AttemptAlloc\fR and \fBTcl_AttemptRealloc\fR are identical in
+function to \fBTcl_Alloc\fR and \fBTcl_Realloc\fR, except that
+\fBTcl_AttemptAlloc\fR and \fBTcl_AttemptRealloc\fR will not cause the Tcl
+interpreter to \fBpanic\fR if the memory allocation fails.  If the

+.SH ARGUMENTS
+.AS Tcl_Interp *interp
+.AP Tcl_Interp *interp in

+.BE
+
+.SH DESCRIPTION
+.PP
+\fBTcl_AppInit\fR is a
+.QW hook
+procedure that is invoked by
+the main programs for Tcl applications such as \fBtclsh\fR and \fBwish\fR.
+Its purpose is to allow new Tcl applications to be created without
+modifying the main programs provided as part of Tcl and Tk.
+To create a new application you write a new version of
+\fBTcl_AppInit\fR to replace the default version provided by Tcl,
+then link your new \fBTcl_AppInit\fR with the Tcl library.
+.PP
+\fBTcl_AppInit\fR is invoked by \fBTcl_Main\fR and \fBTk_Main\fR
+after their own initialization and before entering the main loop
+to process commands.
+Here are some examples of things that \fBTcl_AppInit\fR might do:
+.IP [1]
+Call initialization procedures for various packages used by
+the application.
+Each initialization procedure adds new commands to \fIinterp\fR
+for its package and performs other package-specific initialization.
+.IP [2]
+Process command-line arguments, which can be accessed from the
+Tcl variables \fBargv\fR and \fBargv0\fR in \fIinterp\fR.
+.IP [3]
+Invoke a startup script to initialize the application.
+.IP [4]
+Use the routines \fBTcl_SetStartupScript\fR and
+\fBTcl_GetStartupScript\fR to set or query the file and encoding
+that the active \fBTcl_Main\fR or \fBTk_Main\fR routine will
+use as a startup script. 
+.LP
+\fBTcl_AppInit\fR returns \fBTCL_OK\fR or \fBTCL_ERROR\fR.
+If it returns \fBTCL_ERROR\fR then it must leave an error message in
+for the interpreter's result;  otherwise the result is ignored.
+.PP
+In addition to \fBTcl_AppInit\fR, your application should also contain
+a procedure \fBmain\fR that calls \fBTcl_Main\fR as follows:
+.PP
+.CS
+Tcl_Main(argc, argv, Tcl_AppInit);
+.CE
+.PP
+The third argument to \fBTcl_Main\fR gives the address of the
+application-specific initialization procedure to invoke.
+This means that you do not have to use the name \fBTcl_AppInit\fR
+for the procedure, but in practice the name is nearly always
+\fBTcl_AppInit\fR (in versions before Tcl 7.4 the name \fBTcl_AppInit\fR
+was implicit;  there was no way to specify the procedure explicitly).
+The best way to get started is to make a copy of the file
+\fBtclAppInit.c\fR from the Tcl library or source directory.
+It already contains a \fBmain\fR procedure and a template for
+\fBTcl_AppInit\fR that you can modify for your application.

+.BE
+
+.SH DESCRIPTION
+.PP
+These procedures allow extensions to associate their own data with
+a Tcl interpreter.
+An association consists of a string key, typically the name of
+the extension, and a one-word value, which is typically a pointer
+to a data structure holding data specific to the extension.
+Tcl makes no interpretation of either the key or the value for
+an association.
+.PP
+Storage management is facilitated by storing with each association a
+procedure to call when the interpreter is deleted. This
+procedure can dispose of the storage occupied by the client's data in any
+way it sees fit.
+.PP
+\fBTcl_SetAssocData\fR creates an association between a string
+key and a user specified datum in the given interpreter.
+If there is already an association with the given \fIkey\fR,
+\fBTcl_SetAssocData\fR overwrites it with the new information.
+It is up to callers to organize their use of names to avoid conflicts,
+for example, by using package names as the keys.
+If the \fIdeleteProc\fR argument is non-NULL it specifies the address of a
+procedure to invoke if the interpreter is deleted before the association
+is deleted.  \fIDeleteProc\fR should have arguments and result that match
+the type \fBTcl_InterpDeleteProc\fR:
+.PP
+.CS
+typedef void \fBTcl_InterpDeleteProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR);
+.CE
+.PP
+When \fIdeleteProc\fR is invoked the \fIclientData\fR and \fIinterp\fR
+arguments will be the same as the corresponding arguments passed to
+\fBTcl_SetAssocData\fR.
+The deletion procedure will \fInot\fR be invoked if the association
+is deleted before the interpreter is deleted.
+.PP
+\fBTcl_GetAssocData\fR returns the datum stored in the association with the
+specified key in the given interpreter, and if the \fIdelProcPtr\fR field
+is non-\fBNULL\fR, the address indicated by it gets the address of the
+delete procedure stored with this association. If no association with the
+specified key exists in the given interpreter \fBTcl_GetAssocData\fR
+returns \fBNULL\fR.
+.PP
+\fBTcl_DeleteAssocData\fR deletes an association with a specified key in
+the given interpreter.  Then it calls the deletion procedure.

+.BE
+
+.SH DESCRIPTION
+.PP
+These procedures provide a safe mechanism for dealing with
+asynchronous events such as signals.
+If an event such as a signal occurs while a Tcl script is being
+evaluated then it is not safe to take any substantive action to
+process the event.
+For example, it is not safe to evaluate a Tcl script since the
+interpreter may already be in the middle of evaluating a script;
+it may not even be safe to allocate memory, since a memory
+allocation could have been in progress when the event occurred.
+The only safe approach is to set a flag indicating that the event
+occurred, then handle the event later when the world has returned
+to a clean state, such as after the current Tcl command completes.
+.PP
+\fBTcl_AsyncCreate\fR, \fBTcl_AsyncDelete\fR, and \fBTcl_AsyncReady\fR
+are thread sensitive.  They access and/or set a thread-specific data
+structure in the event of a core built with \fI\-\-enable\-threads\fR.  The token
+created by \fBTcl_AsyncCreate\fR contains the needed thread information it
+was called from so that calling \fBTcl_AsyncMark\fR(\fItoken\fR) will only yield
+the origin thread into the asynchronous handler.
+.PP
+\fBTcl_AsyncCreate\fR creates an asynchronous handler and returns
+a token for it.
+The asynchronous handler must be created before
+any occurrences of the asynchronous event that it is intended
+to handle (it is not safe to create a handler at the time of
+an event).
+When an asynchronous event occurs the code that detects the event
+(such as a signal handler) should call \fBTcl_AsyncMark\fR with the
+token for the handler.
+\fBTcl_AsyncMark\fR will mark the handler as ready to execute, but it
+will not invoke the handler immediately.
+Tcl will call the \fIproc\fR associated with the handler later, when
+the world is in a safe state, and \fIproc\fR can then carry out
+the actions associated with the asynchronous event.
+\fIProc\fR should have arguments and result that match the
+type \fBTcl_AsyncProc\fR:
+.PP
+.CS
+typedef int \fBTcl_AsyncProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        int \fIcode\fR);
+.CE
+.PP
+The \fIclientData\fR will be the same as the \fIclientData\fR
+argument passed to \fBTcl_AsyncCreate\fR when the handler was
+created.
+If \fIproc\fR is invoked just after a command has completed
+execution in an interpreter, then \fIinterp\fR will identify
+the interpreter in which the command was evaluated and
+\fIcode\fR will be the completion code returned by that
+command.
+The command's result will be present in the interpreter's result.
+When \fIproc\fR returns, whatever it leaves in the interpreter's result
+will be returned as the result of the command and the integer
+value returned by \fIproc\fR will be used as the new completion
+code for the command.
+.PP
+It is also possible for \fIproc\fR to be invoked when no interpreter
+is active.
+This can happen, for example, if an asynchronous event occurs while
+the application is waiting for interactive input or an X event.
+In this case \fIinterp\fR will be NULL and \fIcode\fR will be
+0, and the return value from \fIproc\fR will be ignored.
+.PP
+The procedure \fBTcl_AsyncInvoke\fR is called to invoke all of the
+handlers that are ready.
+The procedure \fBTcl_AsyncReady\fR will return non-zero whenever any
+asynchronous handlers are ready;  it can be checked to avoid calls
+to \fBTcl_AsyncInvoke\fR when there are no ready handlers.
+Tcl calls \fBTcl_AsyncReady\fR after each command is evaluated
+and calls \fBTcl_AsyncInvoke\fR if needed.
+Applications may also call \fBTcl_AsyncInvoke\fR at interesting
+times for that application.
+For example, Tcl's event handler calls \fBTcl_AsyncReady\fR
+after each event and calls \fBTcl_AsyncInvoke\fR if needed.
+The \fIinterp\fR and \fIcode\fR arguments to \fBTcl_AsyncInvoke\fR
+have the same meaning as for \fIproc\fR:  they identify the active
+interpreter, if any, and the completion code from the command
+that just completed.
+.PP
+\fBTcl_AsyncDelete\fR removes an asynchronous handler so that
+its \fIproc\fR will never be invoked again.
+A handler can be deleted even when ready, and it will still
+not be invoked.
+.PP
+If multiple handlers become active at the same time, the
+handlers are invoked in the order they were created (oldest
+handler first).
+The \fIcode\fR and the interpreter's result for later handlers
+reflect the values returned by earlier handlers, so that
+the most recently created handler has last say about
+the interpreter's result and completion code.
+If new handlers become ready while handlers are executing,
+\fBTcl_AsyncInvoke\fR will invoke them all;  at each point it
+invokes the highest-priority (oldest) ready handler, repeating
+this over and over until there are no longer any ready handlers.
+.SH WARNING
+.PP
+It is almost always a bad idea for an asynchronous event
+handler to modify the interpreter's result or return a code different
+from its \fIcode\fR argument.
+This sort of behavior can disrupt the execution of scripts in
+subtle ways and result in bugs that are extremely difficult
+to track down.
+If an asynchronous event handler needs to evaluate Tcl scripts
+then it should first save the interpreter's state by calling
+\fBTcl_SaveInterpState\fR, passing in the \fIcode\fR argument.
+When the asynchronous handler is finished it should restore
+the interpreter's state by calling \fBTcl_RestoreInterpState\fR,
+and then returning the \fIcode\fR argument.

+.BE
+
+.SH DESCRIPTION
+.PP
+This procedure is typically invoked when a Tcl exception (any
+return code other than TCL_OK) occurs during
+.QW "background processing"
+such as executing an event handler.
+When such an exception occurs, the condition is reported to Tcl
+or to a widget or some other C code, and there is not usually any
+obvious way for that code to report the exception to the user.
+In these cases the code calls \fBTcl_BackgroundException\fR with an
+\fIinterp\fR argument identifying the interpreter in which the
+exception occurred, and a \fIcode\fR argument holding the return
+code value of the exception.  The state of the interpreter, including
+any error message in the interpreter result, and the values of
+any entries in the return options dictionary, is captured and
+saved.  \fBTcl_BackgroundException\fR then arranges for the event
+loop to invoke at some later time the command registered
+in that interpreter to handle background errors by the
+\fBinterp bgerror\fR command, passing the captured values as
+arguments.
+The registered handler command is meant to report the exception
+in an application-specific fashion.  The handler command
+receives two arguments, the result of the interp, and the
+return options of the interp at the time the error occurred.
+If the application registers no handler command, the default
+handler command will attempt to call \fBbgerror\fR to report
+the error.  If an error condition arises while invoking the
+handler command, then \fBTcl_BackgroundException\fR reports the
+error itself by printing a message on the standard error file.
+.PP
+\fBTcl_BackgroundException\fR does not invoke the handler command immediately
+because this could potentially interfere with scripts that are in process
+at the time the error occurred.
+Instead, it invokes the handler command later as an idle callback.
+.PP
+It is possible for many background exceptions to accumulate before
+the handler command is invoked.  When this happens, each of the exceptions
+is processed in order.  However, if the handler command returns a
+break exception, then all remaining error reports for the
+interpreter are skipped.
+.PP
+The \fBTcl_BackgroundError\fR routine is an older and simpler interface
+useful when the exception code reported is \fBTCL_ERROR\fR.  It is
+equivalent to:

+These procedures are used to pass boolean values to and from
+Tcl as Tcl_Obj's.  When storing a boolean value into a Tcl_Obj,
+any non-zero integer value in \fIboolValue\fR is taken to be
+the boolean value \fB1\fR, and the integer value \fB0\fR is
+taken to be the boolean value \fB0\fR.
+.PP
+\fBTcl_NewBooleanObj\fR creates a new Tcl_Obj, stores the boolean

+The new Tcl_Obj has reference count of zero.
+.PP
+\fBTcl_SetBooleanObj\fR accepts \fIobjPtr\fR, a pointer to
+an existing Tcl_Obj, and stores in the Tcl_Obj \fI*objPtr\fR 
+the boolean value \fIboolValue\fR.  This is a write operation
+on \fI*objPtr\fR, so \fIobjPtr\fR must be unshared.  Attempts to
+write to a shared Tcl_Obj will panic.  A successful write
+of \fIboolValue\fR into \fI*objPtr\fR implies the freeing of
+any former value stored in \fI*objPtr\fR.
+.PP
+\fBTcl_GetBooleanFromObj\fR attempts to retrieve a boolean value
+from the value stored in \fI*objPtr\fR.
+If \fIobjPtr\fR holds a string value recognized by \fBTcl_GetBoolean\fR,
+then the recognized boolean value is written at the address given
+by \fIboolPtr\fR.  
+If \fIobjPtr\fR holds any value recognized as
+a number by Tcl, then if that value is zero a 0 is written at
+the address given by \fIboolPtr\fR and if that
+value is non-zero a 1 is written at the address given by \fIboolPtr\fR.
+In all cases where a value is written at the address given
+by \fIboolPtr\fR, \fBTcl_GetBooleanFromObj\fR returns \fBTCL_OK\fR.
+If the value of \fIobjPtr\fR does not meet any of the conditions
+above, then \fBTCL_ERROR\fR is returned and an error message is 
+left in the interpreter's result unless \fIinterp\fR is NULL.
+\fBTcl_GetBooleanFromObj\fR may also make changes to the internal
+fields of \fI*objPtr\fR so that future calls to 
+\fBTcl_GetBooleanFromObj\fR on the same \fIobjPtr\fR can be
+performed more efficiently.
+.PP
+Note that the routines \fBTcl_GetBooleanFromObj\fR and
+\fBTcl_GetBoolean\fR are not functional equivalents.
+The set of values for which \fBTcl_GetBooleanFromObj\fR
+will return \fBTCL_OK\fR is strictly larger than
+the set of values for which \fBTcl_GetBoolean\fR will do the same.
+For example, the value
+.QW 5
+passed to \fBTcl_GetBooleanFromObj\fR
+will lead to a \fBTCL_OK\fR return (and the boolean value 1),
+while the same value passed to \fBTcl_GetBoolean\fR will lead to
+a \fBTCL_ERROR\fR return.

+.AP Tcl_Obj *objPtr in/out
+For \fBTcl_SetByteArrayObj\fR, this points to the value to be converted to

+the byte-array value; if \fIobjPtr\fR does not already point to a byte-array
+value, it will be converted to one.
+.AP int *lengthPtr out
+If non-NULL, filled with the length of the array of bytes in the value.
+.BE
+
+.SH DESCRIPTION
+.PP
+These procedures are used to create, modify, and read Tcl byte-array values
+from C code.  Byte-array values are typically used to hold the
+results of binary IO operations or data structures created with the
+\fBbinary\fR command.  In Tcl, an array of bytes is not equivalent to a
+string.  Conceptually, a string is an array of Unicode characters, while a
+byte-array is an array of 8-bit quantities with no implicit meaning.
+Accessor functions are provided to get the string representation of a
+byte-array or to convert an arbitrary value to a byte-array.  Obtaining the
+string representation of a byte-array value (by calling
+\fBTcl_GetStringFromObj\fR) produces a properly formed UTF-8 sequence with a
+one-to-one mapping between the bytes in the internal representation and the
+UTF-8 characters in the string representation.
+.PP
+\fBTcl_NewByteArrayObj\fR and \fBTcl_SetByteArrayObj\fR will
+create a new value of byte-array type or modify an existing value to have a
+byte-array type.  Both of these procedures set the value's type to be
+byte-array and set the value's internal representation to a copy of the
+array of bytes given by \fIbytes\fR. \fBTcl_NewByteArrayObj\fR returns a
+pointer to a newly allocated value with a reference count of zero.
+\fBTcl_SetByteArrayObj\fR invalidates any old string representation and, if
+the value is not already a byte-array value, frees any old internal
+representation. If \fIbytes\fR is NULL then the new byte array contains
+arbitrary values.
+.PP
+\fBTcl_GetByteArrayFromObj\fR converts a Tcl value to byte-array type and
+returns a pointer to the value's new internal representation as an array of
+bytes.  The length of this array is stored in \fIlengthPtr\fR if
+\fIlengthPtr\fR is non-NULL.  The storage for the array of bytes is owned by
+the value and should not be freed.  The contents of the array may be
+modified by the caller only if the value is not shared and the caller
+invalidates the string representation.
+.PP
+\fBTcl_SetByteArrayLength\fR converts the Tcl value to byte-array type
+and changes the length of the value's internal representation as an
+array of bytes.  If \fIlength\fR is greater than the space currently
+allocated for the array, the array is reallocated to the new length; the
+newly allocated bytes at the end of the array have arbitrary values.  If
+\fIlength\fR is less than the space currently allocated for the array,
+the length of array is reduced to the new length.  The return value is a
+pointer to the value's new array of bytes.

+.PP
+\fBTcl_CallWhenDeleted\fR arranges for \fIproc\fR to be called by
+\fBTcl_DeleteInterp\fR if/when \fIinterp\fR is deleted at some future
+time.  \fIProc\fR will be invoked just before the interpreter

+.PP
+The \fIclientData\fR and \fIinterp\fR parameters are
+copies of the \fIclientData\fR and \fIinterp\fR arguments given
+to \fBTcl_CallWhenDeleted\fR.
+Typically, \fIclientData\fR points to an application-specific
+data structure that \fIproc\fR uses to perform cleanup when an
+interpreter is about to go away.
+\fIProc\fR does not return a value.
+.PP
+\fBTcl_DontCallWhenDeleted\fR cancels a previous call to
+\fBTcl_CallWhenDeleted\fR with the same arguments, so that
+\fIproc\fR will not be called after all when \fIinterp\fR is
+deleted.
+If there is no deletion callback that matches \fIinterp\fR,
+\fIproc\fR, and \fIclientData\fR then the call to
+\fBTcl_DontCallWhenDeleted\fR has no effect.
+.PP
+Note that if the callback is being used to delete a resource that \fImust\fR
+be released on exit, \fBTcl_CreateExitHandler\fR should be used to ensure that
+a callback is received even if the application terminates without deleting the interpreter.

+\fBTcl_Canceled\fR checks if the script in progress has been canceled and
+returns \fBTCL_ERROR\fR if it has.  Otherwise, \fBTCL_OK\fR is returned.

+
+.SH DESCRIPTION
+.PP
+These functions are for use by extensions that add processing layers to Tcl
+I/O channels.  Examples include compression and encryption modules.  These
+functions transparently stack and unstack a new channel on top of an
+existing one.  Any number of channels can be stacked together.
+.PP
+The implementation of the Tcl channel code was rewritten in 8.3.2 to
+correct some problems with the previous implementation with regard to
+stacked channels.  Anyone using stacked channels or creating stacked
+channel drivers should update to the new \fBTCL_CHANNEL_VERSION_2\fR
+\fBTcl_ChannelType\fR structure.  See \fBTcl_CreateChannel\fR for details.
+.PP
+\fBTcl_StackChannel\fR stacks a new \fIchannel\fR on an existing channel
+with the same name that was registered for \fIchannel\fR by
+\fBTcl_RegisterChannel\fR.
+.PP
+\fBTcl_StackChannel\fR works by creating a new channel structure and
+placing itself on top of the channel stack.  EOL translation, encoding and
+buffering options are shared between all channels in the stack.  The hidden
+channel does no buffering, newline translations, or character set encoding.
+Instead, the buffering, newline translations, and encoding functions all
+remain at the top of the channel stack.  A pointer to the new top channel
+structure is returned.  If an error occurs when stacking the channel, NULL
+is returned instead.
+.PP
+The \fImask\fR parameter specifies the operations that are allowed on the
+new channel.  These can be a subset of the operations allowed on the
+original channel.  For example, a read-write channel may become read-only
+after the \fBTcl_StackChannel\fR call.
+.PP
+Closing a channel closes the channels stacked below it.  The close of
+stacked channels is executed in a way that allows buffered data to be
+properly flushed.
+.PP
+\fBTcl_UnstackChannel\fR reverses the process.  The old channel is
+associated with the channel name, and the processing module added by
+\fBTcl_StackChannel\fR is destroyed.  If there is no old channel, then
+\fBTcl_UnstackChannel\fR is equivalent to \fBTcl_Close\fR.  If an error
+occurs unstacking the channel, \fBTCL_ERROR\fR is returned, otherwise
+\fBTCL_OK\fR is returned.
+.PP
+\fBTcl_GetTopChannel\fR returns the top channel in the stack of
+channels the supplied channel is part of.
+.PP
+\fBTcl_GetStackedChannel\fR returns the channel in the stack of
+channels which is just below the supplied channel.

+.SH DESCRIPTION
+.PP
+Objects are typed entities that have a set of operations ("methods")
+associated with them. Classes are objects that can manufacture objects. Each
+class can be viewed as an object itself; the object view can be retrieved
+using \fBTcl_GetClassAsObject\fR which always returns the object when applied
+to a non-destroyed class, and an object can be viewed as a class with the aid
+of the \fBTcl_GetObjectAsClass\fR (which either returns the class, or NULL if
+the object is not a class). An object may be looked up using the
+\fBTcl_GetObjectFromObj\fR function, which either returns an object or NULL
+(with an error message in the interpreter result) if the object cannot be
+found. The correct way to look up a class by name is to look up the object
+with that name, and then to use \fBTcl_GetObjectAsClass\fR.
+.PP
+Every object has its own command and namespace associated with it. The command
+may be retrieved using the \fBTcl_GetObjectCommand\fR function, the name of
+the object (and hence the name of the command) with \fBTcl_GetObjectName\fR,
+and the namespace may be retrieved using the \fBTcl_GetObjectNamespace\fR
+function. Note that the Tcl_Obj reference returned by \fBTcl_GetObjectName\fR
+is a shared reference.
+.PP
+Instances of classes are created using \fBTcl_NewObjectInstance\fR, which
+takes creates an object from any class (and which is internally called by both
+the \fBcreate\fR and \fBnew\fR methods of the \fBoo::class\fR class). It takes
+parameters that optionally give the name of the object and namespace to
+create, and which describe the arguments to pass to the class's constructor
+(if any). The result of the function will be either a reference to the newly
+created object, or NULL if the creation failed (when an error message will be
+left in the interpreter result). In addition, objects may be copied by using
+\fBTcl_CopyObjectInstance\fR which creates a copy of an object without running
+any constructors.
+.SH "OBJECT AND CLASS METADATA"
+.PP
+Every object and every class may have arbitrary amounts of metadata attached
+to it, which the object or class attaches no meaning to beyond what is
+described in a Tcl_ObjectMetadataType structure instance. Metadata to be
+attached is described by the type of the metadata (given in the
+\fImetaTypePtr\fR argument) and an arbitrary pointer (the \fImetadata\fR
+argument) that are given to \fBTcl_ObjectSetMetadata\fR and
+\fBTcl_ClassSetMetadata\fR, and a particular piece of metadata can be
+retrieved given its type using \fBTcl_ObjectGetMetadata\fR and
+\fBTcl_ClassGetMetadata\fR. If the \fImetadata\fR parameter to either
+\fBTcl_ObjectSetMetadata\fR or \fBTcl_ClassSetMetadata\fR is NULL, the
+metadata is removed if it was attached, and the results of
+\fBTcl_ObjectGetMetadata\fR and \fBTcl_ClassGetMetadata\fR are NULL if the
+given type of metadata was not attached. It is not an error to request or
+remove a piece of metadata that was not attached.
+.SS "TCL_OBJECTMETADATATYPE STRUCTURE"
+.PP
+The contents of the Tcl_ObjectMetadataType structure are as follows:
+.PP
+.CS
+typedef const struct {
+    int \fIversion\fR;
+    const char *\fIname\fR;
+    Tcl_ObjectMetadataDeleteProc *\fIdeleteProc\fR;
+    Tcl_CloneProc *\fIcloneProc\fR;
+} \fBTcl_ObjectMetadataType\fR;
+.CE
+.PP
+The \fIversion\fR field allows for future expansion of the structure, and
+should always be declared equal to TCL_OO_METADATA_VERSION_CURRENT. The
+\fIname\fR field provides a human-readable name for the type, and is reserved
+for debugging.
+.PP
+The \fIdeleteProc\fR field gives a function of type
+Tcl_ObjectMetadataDeleteProc that is used to delete a particular piece of
+metadata, and is called when the attached metadata is replaced or removed; the
+field must not be NULL.
+.PP
+The \fIcloneProc\fR field gives a function that is used to copy a piece of
+metadata (used when a copy of an object is created using
+\fBTcl_CopyObjectInstance\fR); if NULL, the metadata will be just directly
+copied.
+.SS "TCL_OBJECTMETADATADELETEPROC FUNCTION SIGNATURE"
+.PP
+Functions matching this signature are used to delete metadata associated with
+a class or object.
+.PP
+.CS
+typedef void \fBTcl_ObjectMetadataDeleteProc\fR(
+        ClientData \fImetadata\fR);
+.CE
+.PP
+The \fImetadata\fR argument gives the address of the metadata to be
+deleted.
+.SS "TCL_CLONEPROC FUNCTION SIGNATURE"
+.PP
+Functions matching this signature are used to create copies of metadata
+associated with a class or object.
+.PP
+.CS
+typedef int \fBTcl_CloneProc\fR(
+        Tcl_Interp *\fIinterp\fR,
+        ClientData \fIsrcMetadata\fR,
+        ClientData *\fIdstMetadataPtr\fR);
+.CE
+.PP
+The \fIinterp\fR argument gives a place to write an error message when the
+attempt to clone the object is to fail, in which case the clone procedure must
+also return TCL_ERROR; it should return TCL_OK otherwise.
+The \fIsrcMetadata\fR argument gives the address of the metadata to be cloned,
+and the cloned metadata should be written into the variable pointed to by
+\fIdstMetadataPtr\fR; a NULL should be written if the metadata is to not be
+cloned but the overall object copy operation is still to succeed.
+.SH "OBJECT METHOD NAME MAPPING"
+It is possible to control, on a per-object basis, what methods are invoked
+when a particular method is invoked. Normally this is done by looking up the
+method name in the object and then in the class hierarchy, but fine control of
+exactly what the value used to perform the look up is afforded through the

+.SH DESCRIPTION
+.PP
+\fBTcl_Concat\fR is a utility procedure used by several of the
+Tcl commands.  Given a collection of strings, it concatenates
+them together into a single string, with the original strings
+separated by spaces.  This procedure behaves differently than
+\fBTcl_Merge\fR, in that the arguments are simply concatenated:
+no effort is made to ensure proper list structure.
+However, in most common usage the arguments will all be proper
+lists themselves;  if this is true, then the result will also have
+proper list structure.
+.PP
+\fBTcl_Concat\fR eliminates leading and trailing white space as it
+copies strings from \fBargv\fR to the result.  If an element of
+\fBargv\fR consists of nothing but white space, then that string
+is ignored entirely.  This white-space removal was added to make
+the output of the \fBconcat\fR command cleaner-looking.
+.PP
+The result string is dynamically allocated
+using \fBTcl_Alloc\fR;  the caller must eventually release the space
+by calling \fBTcl_Free\fR.

+.SH DESCRIPTION
+.PP
+Tcl uses a two-layered channel architecture. It provides a generic upper
+layer to enable C and Tcl programs to perform input and output using the
+same APIs for a variety of files, devices, sockets etc. The generic C APIs
+are described in the manual entry for \fBTcl_OpenFileChannel\fR.
+.PP
+The lower layer provides type-specific channel drivers for each type
+of device supported on each platform.  This manual entry describes the
+C APIs used to communicate between the generic layer and the
+type-specific channel drivers.  It also explains how new types of
+channels can be added by providing new channel drivers.
+.PP
+Channel drivers consist of a number of components: First, each channel
+driver provides a \fBTcl_ChannelType\fR structure containing pointers to
+functions implementing the various operations used by the generic layer to
+communicate with the channel driver. The \fBTcl_ChannelType\fR structure
+and the functions referenced by it are described in the section
+\fBTCL_CHANNELTYPE\fR, below.
+.PP
+Second, channel drivers usually provide a Tcl command to create
+instances of that type of channel. For example, the Tcl \fBopen\fR
+command creates channels that use the file and command channel
+drivers, and the Tcl \fBsocket\fR command creates channels that use
+TCP sockets for network communication.
+.PP
+Third, a channel driver optionally provides a C function to open
+channel instances of that type. For example, \fBTcl_OpenFileChannel\fR
+opens a channel that uses the file channel driver, and
+\fBTcl_OpenTcpClient\fR opens a channel that uses the TCP network
+protocol.  These creation functions typically use
+\fBTcl_CreateChannel\fR internally to open the channel.
+.PP
+To add a new type of channel you must implement a C API or a Tcl command
+that opens a channel by invoking \fBTcl_CreateChannel\fR.
+When your driver calls \fBTcl_CreateChannel\fR it passes in
+a \fBTcl_ChannelType\fR structure describing the driver's I/O
+procedures.
+The generic layer will then invoke the functions referenced in that
+structure to perform operations on the channel.
+.PP
+\fBTcl_CreateChannel\fR opens a new channel and associates the supplied
+\fItypePtr\fR and \fIinstanceData\fR with it. The channel is opened in the
+mode indicated by \fImask\fR.
+For a discussion of channel drivers, their operations and the
+\fBTcl_ChannelType\fR structure, see the section \fBTCL_CHANNELTYPE\fR, below.
+.PP
+\fBTcl_CreateChannel\fR interacts with the code managing the standard
+channels. Once a standard channel was initialized either through a
+call to \fBTcl_GetStdChannel\fR or a call to \fBTcl_SetStdChannel\fR
+closing this standard channel will cause the next call to
+\fBTcl_CreateChannel\fR to make the new channel the new standard
+channel too. See \fBTcl_StandardChannels\fR for a general treatise
+about standard channels and the behavior of the Tcl library with
+regard to them.
+.PP
+\fBTcl_GetChannelInstanceData\fR returns the instance data associated with
+the channel in \fIchannel\fR. This is the same as the \fIinstanceData\fR
+argument in the call to \fBTcl_CreateChannel\fR that created this channel.
+.PP
+\fBTcl_GetChannelType\fR returns a pointer to the \fBTcl_ChannelType\fR
+structure used by the channel in the \fIchannel\fR argument. This is
+the same as the \fItypePtr\fR argument in the call to
+\fBTcl_CreateChannel\fR that created this channel.
+.PP
+\fBTcl_GetChannelName\fR returns a string containing the name associated
+with the channel, or NULL if the \fIchannelName\fR argument to
+\fBTcl_CreateChannel\fR was NULL.
+.PP
+\fBTcl_GetChannelHandle\fR places the OS-specific device handle
+associated with \fIchannel\fR for the given \fIdirection\fR in the
+location specified by \fIhandlePtr\fR and returns \fBTCL_OK\fR.  If
+the channel does not have a device handle for the specified direction,
+then \fBTCL_ERROR\fR is returned instead.  Different channel drivers
+will return different types of handle.  Refer to the manual entries
+for each driver to determine what type of handle is returned.
+.PP
+\fBTcl_GetChannelThread\fR returns the id of the thread currently managing
+the specified \fIchannel\fR. This allows channel drivers to send their file
+events to the correct event queue even for a multi-threaded core.
+.PP
+\fBTcl_GetChannelMode\fR returns an OR-ed combination of \fBTCL_READABLE\fR
+and \fBTCL_WRITABLE\fR, indicating whether the channel is open for input
+and output.
+.PP
+\fBTcl_GetChannelBufferSize\fR returns the size, in bytes, of buffers
+allocated to store input or output in \fIchannel\fR. If the value was not set
+by a previous call to \fBTcl_SetChannelBufferSize\fR, described below, then
+the default value of 4096 is returned.
+.PP
+\fBTcl_SetChannelBufferSize\fR sets the size, in bytes, of buffers that
+will be allocated in subsequent operations on the channel to store input or
+output. The \fIsize\fR argument should be between one and one million,
+allowing buffers of one byte to one million bytes. If \fIsize\fR is
+outside this range, \fBTcl_SetChannelBufferSize\fR sets the buffer size to
+4096.
+.PP
+\fBTcl_NotifyChannel\fR is called by a channel driver to indicate to
+the generic layer that the events specified by \fImask\fR have
+occurred on the channel.  Channel drivers are responsible for invoking
+this function whenever the channel handlers need to be called for the
+channel.  See \fBWATCHPROC\fR below for more details.
+.PP
+\fBTcl_BadChannelOption\fR is called from driver specific
+\fIsetOptionProc\fR or \fIgetOptionProc\fR to generate a complete
+error message.
+.PP
+\fBTcl_ChannelBuffered\fR returns the number of bytes of input
+currently buffered in the internal buffer (push back area) of the
+channel itself. It does not report about the data in the overall
+buffers for the stack of channels the supplied channel is part of.
+.PP
+\fBTcl_IsChannelShared\fR checks the refcount of the specified
+\fIchannel\fR and returns whether the \fIchannel\fR was shared among
+multiple interpreters (result == 1) or not (result == 0).
+.PP
+\fBTcl_IsChannelRegistered\fR checks whether the specified \fIchannel\fR is
+registered in the given \fIinterp\fRreter (result == 1) or not
+(result == 0).
+.PP
+\fBTcl_IsChannelExisting\fR checks whether a channel with the specified
+name is registered in the (thread)-global list of all channels (result
+== 1) or not (result == 0).
+.PP
+\fBTcl_CutChannel\fR removes the specified \fIchannel\fR from the
+(thread)global list of all channels (of the current thread).
+Application to a channel still registered in some interpreter
+is not allowed.
+Also notifies the driver if the \fBTcl_ChannelType\fR version is
+\fBTCL_CHANNEL_VERSION_4\fR (or higher), and
+\fBTcl_DriverThreadActionProc\fR is defined for it.
+.PP
+\fBTcl_SpliceChannel\fR adds the specified \fIchannel\fR to the
+(thread)global list of all channels (of the current thread).
+Application to a channel registered in some interpreter is not allowed.
+Also notifies the driver if the \fBTcl_ChannelType\fR version is
+\fBTCL_CHANNEL_VERSION_4\fR (or higher), and
+\fBTcl_DriverThreadActionProc\fR is defined for it.
+.PP
+\fBTcl_ClearChannelHandlers\fR removes all channel handlers and event
+scripts associated with the specified \fIchannel\fR, thus shutting
+down all event processing for this channel.
+.SH TCL_CHANNELTYPE
+.PP
+A channel driver provides a \fBTcl_ChannelType\fR structure that contains
+pointers to functions that implement the various operations on a channel;
+these operations are invoked as needed by the generic layer.  The structure
+was versioned starting in Tcl 8.3.2/8.4 to correct a problem with stacked
+channel drivers.  See the \fBOLD CHANNEL TYPES\fR section below for
+details about the old structure.
+.PP
+The \fBTcl_ChannelType\fR structure contains the following fields:
+.PP
+.CS
+typedef struct Tcl_ChannelType {
+        const char *\fItypeName\fR;
+        Tcl_ChannelTypeVersion \fIversion\fR;
+        Tcl_DriverCloseProc *\fIcloseProc\fR;
+        Tcl_DriverInputProc *\fIinputProc\fR;
+        Tcl_DriverOutputProc *\fIoutputProc\fR;
+        Tcl_DriverSeekProc *\fIseekProc\fR;
+        Tcl_DriverSetOptionProc *\fIsetOptionProc\fR;
+        Tcl_DriverGetOptionProc *\fIgetOptionProc\fR;
+        Tcl_DriverWatchProc *\fIwatchProc\fR;
+        Tcl_DriverGetHandleProc *\fIgetHandleProc\fR;
+        Tcl_DriverClose2Proc *\fIclose2Proc\fR;
+        Tcl_DriverBlockModeProc *\fIblockModeProc\fR;
+        Tcl_DriverFlushProc *\fIflushProc\fR;
+        Tcl_DriverHandlerProc *\fIhandlerProc\fR;
+        Tcl_DriverWideSeekProc *\fIwideSeekProc\fR;
+        Tcl_DriverThreadActionProc *\fIthreadActionProc\fR;
+        Tcl_DriverTruncateProc *\fItruncateProc\fR;
+} \fBTcl_ChannelType\fR;
+.CE
+.PP
+It is not necessary to provide implementations for all channel
+operations.  Those which are not necessary may be set to NULL in the
+struct: \fIblockModeProc\fR, \fIseekProc\fR, \fIsetOptionProc\fR,
+\fIgetOptionProc\fR, and \fIclose2Proc\fR, in addition to
+\fIflushProc\fR, \fIhandlerProc\fR, \fIthreadActionProc\fR, and
+\fItruncateProc\fR.  Other functions that cannot be implemented in a
+meaningful way should return \fBEINVAL\fR when called, to indicate
+that the operations they represent are not available. Also note that
+\fIwideSeekProc\fR can be NULL if \fIseekProc\fR is.
+.PP
+The user should only use the above structure for \fBTcl_ChannelType\fR
+instantiation.  When referencing fields in a \fBTcl_ChannelType\fR
+structure, the following functions should be used to obtain the values:
+\fBTcl_ChannelName\fR, \fBTcl_ChannelVersion\fR,
+\fBTcl_ChannelBlockModeProc\fR, \fBTcl_ChannelCloseProc\fR,
+\fBTcl_ChannelClose2Proc\fR, \fBTcl_ChannelInputProc\fR,
+\fBTcl_ChannelOutputProc\fR, \fBTcl_ChannelSeekProc\fR,
+\fBTcl_ChannelWideSeekProc\fR, \fBTcl_ChannelThreadActionProc\fR,
+\fBTcl_ChannelTruncateProc\fR,
+\fBTcl_ChannelSetOptionProc\fR, \fBTcl_ChannelGetOptionProc\fR,
+\fBTcl_ChannelWatchProc\fR, \fBTcl_ChannelGetHandleProc\fR,
+\fBTcl_ChannelFlushProc\fR, or \fBTcl_ChannelHandlerProc\fR.
+.PP
+The change to the structures was made in such a way that standard channel
+types are binary compatible.  However, channel types that use stacked
+channels (i.e. TLS, Trf) have new versions to correspond to the above change
+since the previous code for stacked channels had problems.
+.SS TYPENAME
+.PP
+The \fItypeName\fR field contains a null-terminated string that
+identifies the type of the device implemented by this driver, e.g.
+\fBfile\fR or \fBsocket\fR.
+.PP
+This value can be retrieved with \fBTcl_ChannelName\fR, which returns
+a pointer to the string.
+.SS VERSION
+.PP
+
+The \fIversion\fR field should be set to the version of the structure
+that you require. \fBTCL_CHANNEL_VERSION_2\fR is the minimum recommended.
+\fBTCL_CHANNEL_VERSION_3\fR must be set to specify the \fIwideSeekProc\fR member.
+\fBTCL_CHANNEL_VERSION_4\fR must be set to specify the \fIthreadActionProc\fR member
+(includes \fIwideSeekProc\fR).
+\fBTCL_CHANNEL_VERSION_5\fR must be set to specify the
+\fItruncateProc\fR members (includes
+\fIwideSeekProc\fR and \fIthreadActionProc\fR).
+If it is not set to any of these, then this
+\fBTcl_ChannelType\fR is assumed to have the original structure.  See
+\fBOLD CHANNEL TYPES\fR for more details.  While Tcl will recognize
+and function with either structures, stacked channels must be of at
+least \fBTCL_CHANNEL_VERSION_2\fR to function correctly.
+.PP
+This value can be retrieved with \fBTcl_ChannelVersion\fR, which returns
+one of
+\fBTCL_CHANNEL_VERSION_5\fR,
+\fBTCL_CHANNEL_VERSION_4\fR,
+\fBTCL_CHANNEL_VERSION_3\fR,
+\fBTCL_CHANNEL_VERSION_2\fR or \fBTCL_CHANNEL_VERSION_1\fR.
+.SS BLOCKMODEPROC
+.PP
+The \fIblockModeProc\fR field contains the address of a function called by
+the generic layer to set blocking and nonblocking mode on the device.
+\fIBlockModeProc\fR should match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_DriverBlockModeProc\fR(
+        ClientData \fIinstanceData\fR,
+        int \fImode\fR);
+.CE
+.PP
+The \fIinstanceData\fR is the same as the value passed to
+\fBTcl_CreateChannel\fR when this channel was created.  The \fImode\fR
+argument is either \fBTCL_MODE_BLOCKING\fR or \fBTCL_MODE_NONBLOCKING\fR to
+set the device into blocking or nonblocking mode. The function should
+return zero if the operation was successful, or a nonzero POSIX error code
+if the operation failed.
+.PP
+If the operation is successful, the function can modify the supplied
+\fIinstanceData\fR to record that the channel entered blocking or
+nonblocking mode and to implement the blocking or nonblocking behavior.
+For some device types, the blocking and nonblocking behavior can be
+implemented by the underlying operating system; for other device types, the
+behavior must be emulated in the channel driver.
+.PP
+This value can be retrieved with \fBTcl_ChannelBlockModeProc\fR, which returns
+a pointer to the function.
+.PP
+A channel driver \fBnot\fR supplying a \fIblockModeProc\fR has to be
+very, very careful. It has to tell the generic layer exactly which
+blocking mode is acceptable to it, and should this also document for
+the user so that the blocking mode of the channel is not changed to an
+unacceptable value. Any confusion here may lead the interpreter into a
+(spurious and difficult to find) deadlock.
+.SS "CLOSEPROC AND CLOSE2PROC"
+.PP
+The \fIcloseProc\fR field contains the address of a function called by the
+generic layer to clean up driver-related information when the channel is
+closed. \fICloseProc\fR must match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_DriverCloseProc\fR(
+        ClientData \fIinstanceData\fR,
+        Tcl_Interp *\fIinterp\fR);
+.CE
+.PP
+The \fIinstanceData\fR argument is the same as the value provided to
+\fBTcl_CreateChannel\fR when the channel was created. The function should
+release any storage maintained by the channel driver for this channel, and
+close the input and output devices encapsulated by this channel. All queued
+output will have been flushed to the device before this function is called,

+.PP
+Alternatively, channels that support closing the read and write sides
+independently may set \fIcloseProc\fR to \fBTCL_CLOSE2PROC\fR and set
+\fIclose2Proc\fR to the address of a function that matches the

+.CE
+.PP
+The \fIclose2Proc\fR will be called with \fIflags\fR set to an OR'ed
+combination of \fBTCL_CLOSE_READ\fR or \fBTCL_CLOSE_WRITE\fR to
+indicate that the driver should close the read and/or write side of
+the channel.  The channel driver may be invoked to perform
+additional operations on the channel after \fIclose2Proc\fR is
+called to close one or both sides of the channel.  If \fIflags\fR is
+\fB0\fR (zero), the driver should close the channel in the manner
+described above for \fIcloseProc\fR.  No further operations will be
+invoked on this instance after \fIclose2Proc\fR is called with all
+flags cleared.  In all cases, the \fIclose2Proc\fR function should
+return zero if the close operation was successful; otherwise it should
+return a nonzero POSIX error code. In addition, if an error occurs and

+.PP
+The \fIcloseProc\fR and \fIclose2Proc\fR values can be retrieved with
+\fBTcl_ChannelCloseProc\fR or \fBTcl_ChannelClose2Proc\fR, which
+return a pointer to the respective function.
+.SS INPUTPROC
+.PP
+The \fIinputProc\fR field contains the address of a function called by the
+generic layer to read data from the file or device and store it in an
+internal buffer. \fIInputProc\fR must match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_DriverInputProc\fR(
+        ClientData \fIinstanceData\fR,
+        char *\fIbuf\fR,
+        int \fIbufSize\fR,
+        int *\fIerrorCodePtr\fR);
+.CE
+.PP
+\fIInstanceData\fR is the same as the value passed to
+\fBTcl_CreateChannel\fR when the channel was created.  The \fIbuf\fR
+argument points to an array of bytes in which to store input from the
+device, and the \fIbufSize\fR argument indicates how many bytes are
+available at \fIbuf\fR.
+.PP
+The \fIerrorCodePtr\fR argument points to an integer variable provided by
+the generic layer. If an error occurs, the function should set the variable
+to a POSIX error code that identifies the error that occurred.
+.PP
+The function should read data from the input device encapsulated by the
+channel and store it at \fIbuf\fR.  On success, the function should return
+a nonnegative integer indicating how many bytes were read from the input
+device and stored at \fIbuf\fR. On error, the function should return -1. If
+an error occurs after some data has been read from the device, that data is
+lost.
+.PP
+If \fIinputProc\fR can determine that the input device has some data
+available but less than requested by the \fIbufSize\fR argument, the
+function should only attempt to read as much data as is available and
+return without blocking. If the input device has no data available
+whatsoever and the channel is in nonblocking mode, the function should
+return an \fBEAGAIN\fR error. If the input device has no data available
+whatsoever and the channel is in blocking mode, the function should block
+for the shortest possible time until at least one byte of data can be read
+from the device; then, it should return as much data as it can read without
+blocking.
+.PP
+This value can be retrieved with \fBTcl_ChannelInputProc\fR, which returns
+a pointer to the function.
+.SS OUTPUTPROC
+.PP
+The \fIoutputProc\fR field contains the address of a function called by the
+generic layer to transfer data from an internal buffer to the output device.
+\fIOutputProc\fR must match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_DriverOutputProc\fR(
+        ClientData \fIinstanceData\fR,
+        const char *\fIbuf\fR,
+        int \fItoWrite\fR,
+        int *\fIerrorCodePtr\fR);
+.CE
+.PP
+\fIInstanceData\fR is the same as the value passed to
+\fBTcl_CreateChannel\fR when the channel was created. The \fIbuf\fR
+argument contains an array of bytes to be written to the device, and the
+\fItoWrite\fR argument indicates how many bytes are to be written from the
+\fIbuf\fR argument.
+.PP
+The \fIerrorCodePtr\fR argument points to an integer variable provided by
+the generic layer. If an error occurs, the function should set this
+variable to a POSIX error code that identifies the error.
+.PP
+The function should write the data at \fIbuf\fR to the output device
+encapsulated by the channel. On success, the function should return a
+nonnegative integer indicating how many bytes were written to the output
+device.  The return value is normally the same as \fItoWrite\fR, but may be
+less in some cases such as if the output operation is interrupted by a
+signal. If an error occurs the function should return -1.  In case of
+error, some data may have been written to the device.
+.PP
+If the channel is nonblocking and the output device is unable to absorb any
+data whatsoever, the function should return -1 with an \fBEAGAIN\fR error
+without writing any data.
+.PP
+This value can be retrieved with \fBTcl_ChannelOutputProc\fR, which returns
+a pointer to the function.
+.SS "SEEKPROC AND WIDESEEKPROC"
+.PP
+The \fIseekProc\fR field contains the address of a function called by the
+generic layer to move the access point at which subsequent input or output
+operations will be applied. \fISeekProc\fR must match the following
+prototype:
+.PP
+.CS
+typedef int \fBTcl_DriverSeekProc\fR(
+        ClientData \fIinstanceData\fR,
+        long \fIoffset\fR,
+        int \fIseekMode\fR,
+        int *\fIerrorCodePtr\fR);
+.CE
+.PP
+The \fIinstanceData\fR argument is the same as the value given to
+\fBTcl_CreateChannel\fR when this channel was created.  \fIOffset\fR and
+\fIseekMode\fR have the same meaning as for the \fBTcl_Seek\fR
+procedure (described in the manual entry for \fBTcl_OpenFileChannel\fR).
+.PP
+The \fIerrorCodePtr\fR argument points to an integer variable provided by
+the generic layer for returning \fBerrno\fR values from the function.  The
+function should set this variable to a POSIX error code if an error occurs.
+The function should store an \fBEINVAL\fR error code if the channel type
+does not implement seeking.
+.PP
+The return value is the new access point or -1 in case of error. If an
+error occurred, the function should not move the access point.
+.PP
+If there is a non-NULL \fIseekProc\fR field, the \fIwideSeekProc\fR
+field may contain the address of an alternative function to use which
+handles wide (i.e. larger than 32-bit) offsets, so allowing seeks
+within files larger than 2GB.  The \fIwideSeekProc\fR will be called
+in preference to the \fIseekProc\fR, but both must be defined if the
+\fIwideSeekProc\fR is defined.  \fIWideSeekProc\fR must match the
+following prototype:
+.PP
+.CS
+typedef Tcl_WideInt \fBTcl_DriverWideSeekProc\fR(
+        ClientData \fIinstanceData\fR,
+        Tcl_WideInt \fIoffset\fR,
+        int \fIseekMode\fR,
+        int *\fIerrorCodePtr\fR);
+.CE
+.PP
+The arguments and return values mean the same thing as with
+\fIseekProc\fR above, except that the type of offsets and the return
+type are different.
+.PP
+The \fIseekProc\fR value can be retrieved with
+\fBTcl_ChannelSeekProc\fR, which returns a pointer to the function,
+and similarly the \fIwideSeekProc\fR can be retrieved with
+\fBTcl_ChannelWideSeekProc\fR.
+.SS SETOPTIONPROC
+.PP
+The \fIsetOptionProc\fR field contains the address of a function called by
+the generic layer to set a channel type specific option on a channel.
+\fIsetOptionProc\fR must match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_DriverSetOptionProc\fR(
+        ClientData \fIinstanceData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        const char *\fIoptionName\fR,
+        const char *\fInewValue\fR);
+.CE
+.PP
+\fIoptionName\fR is the name of an option to set, and \fInewValue\fR is
+the new value for that option, as a string. The \fIinstanceData\fR is the
+same as the value given to \fBTcl_CreateChannel\fR when this channel was
+created. The function should do whatever channel type specific action is
+required to implement the new value of the option.
+.PP
+Some options are handled by the generic code and this function is never
+called to set them, e.g. \fB\-blockmode\fR. Other options are specific to
+each channel type and the \fIsetOptionProc\fR procedure of the channel
+driver will get called to implement them. The \fIsetOptionProc\fR field can
+be NULL, which indicates that this channel type supports no type specific
+options. 
+.PP
+If the option value is successfully modified to the new value, the function
+returns \fBTCL_OK\fR.
+It should call \fBTcl_BadChannelOption\fR which itself returns
+\fBTCL_ERROR\fR if the \fIoptionName\fR is
+unrecognized. 
+If \fInewValue\fR specifies a value for the option that
+is not supported or if a system call error occurs,
+the function should leave an error message in the
+\fIresult\fR field of \fIinterp\fR if \fIinterp\fR is not NULL. The
+function should also call \fBTcl_SetErrno\fR to store an appropriate POSIX
+error code.
+.PP
+This value can be retrieved with \fBTcl_ChannelSetOptionProc\fR, which returns
+a pointer to the function.
+.SS GETOPTIONPROC
+.PP
+The \fIgetOptionProc\fR field contains the address of a function called by
+the generic layer to get the value of a channel type specific option on a
+channel. \fIgetOptionProc\fR must match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_DriverGetOptionProc\fR(
+        ClientData \fIinstanceData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        const char *\fIoptionName\fR,
+        Tcl_DString *\fIoptionValue\fR);
+.CE
+.PP
+\fIOptionName\fR is the name of an option supported by this type of
+channel. If the option name is not NULL, the function stores its current
+value, as a string, in the Tcl dynamic string \fIoptionValue\fR.
+If \fIoptionName\fR is NULL, the function stores in \fIoptionValue\fR an
+alternating list of all supported options and their current values.
+On success, the function returns \fBTCL_OK\fR. 
+It should call \fBTcl_BadChannelOption\fR which itself returns
+\fBTCL_ERROR\fR if the \fIoptionName\fR is
+unrecognized. If a system call error occurs,
+the function should leave an error message in the
+result of \fIinterp\fR if \fIinterp\fR is not NULL. The
+function should also call \fBTcl_SetErrno\fR to store an appropriate POSIX
+error code.
+.PP
+Some options are handled by the generic code and this function is never
+called to retrieve their value, e.g. \fB\-blockmode\fR. Other options are
+specific to each channel type and the \fIgetOptionProc\fR procedure of the
+channel driver will get called to implement them. The \fIgetOptionProc\fR
+field can be NULL, which indicates that this channel type supports no type
+specific options.
+.PP
+This value can be retrieved with \fBTcl_ChannelGetOptionProc\fR, which returns
+a pointer to the function.
+.SS WATCHPROC
+.PP
+The \fIwatchProc\fR field contains the address of a function called
+by the generic layer to initialize the event notification mechanism to
+notice events of interest on this channel.
+\fIWatchProc\fR should match the following prototype:
+.PP
+.CS
+typedef void \fBTcl_DriverWatchProc\fR(
+        ClientData \fIinstanceData\fR,
+        int \fImask\fR);
+.CE
+.PP
+The \fIinstanceData\fR is the same as the value passed to
+\fBTcl_CreateChannel\fR when this channel was created. The \fImask\fR
+argument is an OR-ed combination of \fBTCL_READABLE\fR, \fBTCL_WRITABLE\fR
+and \fBTCL_EXCEPTION\fR; it indicates events the caller is interested in
+noticing on this channel.
+.PP
+The function should initialize device type specific mechanisms to
+notice when an event of interest is present on the channel.  When one
+or more of the designated events occurs on the channel, the channel
+driver is responsible for calling \fBTcl_NotifyChannel\fR to inform
+the generic channel module.  The driver should take care not to starve
+other channel drivers or sources of callbacks by invoking
+Tcl_NotifyChannel too frequently.  Fairness can be insured by using
+the Tcl event queue to allow the channel event to be scheduled in sequence
+with other events.  See the description of \fBTcl_QueueEvent\fR for
+details on how to queue an event.
+.PP
+This value can be retrieved with \fBTcl_ChannelWatchProc\fR, which returns
+a pointer to the function.
+.SS GETHANDLEPROC
+.PP
+The \fIgetHandleProc\fR field contains the address of a function called by
+the generic layer to retrieve a device-specific handle from the channel.
+\fIGetHandleProc\fR should match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_DriverGetHandleProc\fR(
+        ClientData \fIinstanceData\fR,
+        int \fIdirection\fR,
+        ClientData *\fIhandlePtr\fR);
+.CE
+.PP
+\fIInstanceData\fR is the same as the value passed to
+\fBTcl_CreateChannel\fR when this channel was created. The \fIdirection\fR
+argument is either \fBTCL_READABLE\fR to retrieve the handle used
+for input, or \fBTCL_WRITABLE\fR to retrieve the handle used for
+output.
+.PP
+If the channel implementation has device-specific handles, the
+function should retrieve the appropriate handle associated with the
+channel, according the \fIdirection\fR argument.  The handle should be
+stored in the location referred to by \fIhandlePtr\fR, and
+\fBTCL_OK\fR should be returned.  If the channel is not open for the
+specified direction, or if the channel implementation does not use
+device handles, the function should return \fBTCL_ERROR\fR.
+.PP
+This value can be retrieved with \fBTcl_ChannelGetHandleProc\fR, which returns
+a pointer to the function.
+.SS FLUSHPROC
+.PP
+The \fIflushProc\fR field is currently reserved for future use.
+It should be set to NULL.
+\fIFlushProc\fR should match the following prototype:

+.CE
+.PP
+This value can be retrieved with \fBTcl_ChannelFlushProc\fR, which returns
+a pointer to the function.
+.SS HANDLERPROC
+.PP
+The \fIhandlerProc\fR field contains the address of a function called by
+the generic layer to notify the channel that an event occurred.  It should
+be defined for stacked channel drivers that wish to be notified of events
+that occur on the underlying (stacked) channel.
+\fIHandlerProc\fR should match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_DriverHandlerProc\fR(
+        ClientData \fIinstanceData\fR,
+        int \fIinterestMask\fR);
+.CE
+.PP
+\fIInstanceData\fR is the same as the value passed to \fBTcl_CreateChannel\fR
+when this channel was created.  The \fIinterestMask\fR is an OR-ed
+combination of \fBTCL_READABLE\fR or \fBTCL_WRITABLE\fR; it indicates what
+type of event occurred on this channel.
+.PP
+This value can be retrieved with \fBTcl_ChannelHandlerProc\fR, which returns
+a pointer to the function.
+
+.SS "THREADACTIONPROC"
+.PP
+The \fIthreadActionProc\fR field contains the address of the function
+called by the generic layer when a channel is created, closed, or
+going to move to a different thread, i.e. whenever thread-specific
+driver state might have to initialized or updated. It can be NULL.
+The action \fITCL_CHANNEL_THREAD_REMOVE\fR is used to notify the
+driver that it should update or remove any thread-specific data it
+might be maintaining for the channel.
+.PP
+The action \fITCL_CHANNEL_THREAD_INSERT\fR is used to notify the
+driver that it should update or initialize any thread-specific data it
+might be maintaining using the calling thread as the associate. See
+\fBTcl_CutChannel\fR and \fBTcl_SpliceChannel\fR for more detail.
+.PP

+.SS "TRUNCATEPROC"
+.PP
+The \fItruncateProc\fR field contains the address of the function
+called by the generic layer when a channel is truncated to some
+length. It can be NULL.
+.PP
+.CS
+typedef int \fBTcl_DriverTruncateProc\fR(
+        ClientData \fIinstanceData\fR,
+        Tcl_WideInt \fIlength\fR);
+.CE
+.PP
+\fIInstanceData\fR is the same as the value passed to
+\fBTcl_CreateChannel\fR when this channel was created, and
+\fIlength\fR is the new length of the underlying file, which should
+not be negative. The result should be 0 on success or an errno code
+(suitable for use with \fBTcl_SetErrno\fR) on failure.
+.PP
+These values can be retrieved with \fBTcl_ChannelTruncateProc\fR,
+which returns a pointer to the function.
+.SH TCL_BADCHANNELOPTION
+.PP
+This procedure generates a
+.QW "bad option"
+error message in an
+(optional) interpreter.  It is used by channel drivers when 
+an invalid Set/Get option is requested. Its purpose is to concatenate
+the generic options list to the specific ones and factorize
+the generic options error message string.
+.PP
+It always returns \fBTCL_ERROR\fR
+.PP
+An error message is generated in \fIinterp\fR's result value to
+indicate that a command was invoked with a bad option.
+The message has the form
+.CS
+    bad option "blah": should be one of 
+    <...generic options...>+<...specific options...>
+.CE
+so you get for instance:
+.CS
+    bad option "-blah": should be one of -blocking,

+    -peername, or -sockname
+.CE
+when called with \fIoptionList\fR equal to
+.QW "peername sockname"
+.PP
+.QW blah

+each option, commas after, and an
+.QW or
+before the last option.
+.SH "OLD CHANNEL TYPES"

+.SH DESCRIPTION
+.PP
+\fBTcl_CreateChannelHandler\fR arranges for \fIproc\fR to be called in the
+future whenever input or output becomes possible on the channel identified
+by \fIchannel\fR, or whenever an exceptional condition exists for
+\fIchannel\fR. The conditions of interest under which \fIproc\fR will be
+invoked are specified by the \fImask\fR argument.
+See the manual entry for \fBfileevent\fR for a precise description of
+what it means for a channel to be readable or writable.
+\fIProc\fR must conform to the following prototype:
+.PP
+.CS
+typedef void \fBTcl_ChannelProc\fR(
+        ClientData \fIclientData\fR,
+        int \fImask\fR);
+.CE
+.PP
+The \fIclientData\fR argument is the same as the value passed to
+\fBTcl_CreateChannelHandler\fR when the handler was created. Typically,
+\fIclientData\fR points to a data structure containing application-specific
+information about the channel. \fIMask\fR is an integer mask indicating
+which of the requested conditions actually exists for the channel; it will
+contain a subset of the bits from the \fImask\fR argument to
+\fBTcl_CreateChannelHandler\fR when the handler was created.
+.PP
+Each channel handler is identified by a unique combination of \fIchannel\fR,
+\fIproc\fR and \fIclientData\fR.
+There may be many handlers for a given channel as long as they do not
+have the same \fIchannel\fR, \fIproc\fR, and \fIclientData\fR.
+If \fBTcl_CreateChannelHandler\fR is invoked when there is already a handler
+for \fIchannel\fR, \fIproc\fR, and \fIclientData\fR, then no new
+handler is created;  instead, the \fImask\fR is changed for the
+existing handler.
+.PP
+\fBTcl_DeleteChannelHandler\fR deletes a channel handler identified by
+\fIchannel\fR, \fIproc\fR and \fIclientData\fR; if no such handler exists,
+the call has no effect.
+.PP
+Channel handlers are invoked via the Tcl event mechanism, so they

+.BE
+.SH DESCRIPTION
+.PP
+\fBTcl_CreateCommand\fR defines a new command in \fIinterp\fR and associates
+it with procedure \fIproc\fR such that whenever \fIcmdName\fR is
+invoked as a Tcl command (via a call to \fBTcl_Eval\fR) the Tcl interpreter
+will call \fIproc\fR to process the command.
+It differs from \fBTcl_CreateObjCommand\fR in that a new string-based
+command is defined;
+that is, a command procedure is defined that takes an array of
+argument strings instead of values.
+The value-based command procedures registered by \fBTcl_CreateObjCommand\fR
+can execute significantly faster than the string-based command procedures
+defined by \fBTcl_CreateCommand\fR.
+This is because they take Tcl values as arguments
+and those values can retain an internal representation that
+can be manipulated more efficiently.
+Also, Tcl's interpreter now uses values internally.
+In order to invoke a string-based command procedure
+registered by \fBTcl_CreateCommand\fR,
+it must generate and fetch a string representation
+from each argument value before the call.
+New commands should be defined using \fBTcl_CreateObjCommand\fR.
+We support \fBTcl_CreateCommand\fR for backwards compatibility.
+.PP
+The procedures \fBTcl_DeleteCommand\fR, \fBTcl_GetCommandInfo\fR,
+and \fBTcl_SetCommandInfo\fR are used in conjunction with
+\fBTcl_CreateCommand\fR.
+.PP
+\fBTcl_CreateCommand\fR will delete an existing command \fIcmdName\fR,
+if one is already associated with the interpreter.
+It returns a token that may be used to refer
+to the command in subsequent calls to \fBTcl_GetCommandName\fR.
+If \fIcmdName\fR contains any \fB::\fR namespace qualifiers,
+then the command is added to the specified namespace;
+otherwise the command is added to the global namespace.
+If \fBTcl_CreateCommand\fR is called for an interpreter that is in
+the process of being deleted, then it does not create a new command
+and it returns NULL.
+\fIProc\fR should have arguments and result that match the type
+\fBTcl_CmdProc\fR:
+.PP
+.CS
+typedef int \fBTcl_CmdProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        int \fIargc\fR,
+        const char *\fIargv\fR[]);
+.CE
+.PP
+When \fIproc\fR is invoked the \fIclientData\fR and \fIinterp\fR
+parameters will be copies of the \fIclientData\fR and \fIinterp\fR
+arguments given to \fBTcl_CreateCommand\fR.
+Typically, \fIclientData\fR points to an application-specific
+data structure that describes what to do when the command procedure
+is invoked.  \fIArgc\fR and \fIargv\fR describe the arguments to
+the command, \fIargc\fR giving the number of arguments (including
+the command name) and \fIargv\fR giving the values of the arguments
+as strings.  The \fIargv\fR array will contain \fIargc\fR+1 values;
+the first \fIargc\fR values point to the argument strings, and the
+last value is NULL.  
+Note that the argument strings should not be modified as they may
+point to constant strings or may be shared with other parts of the
+interpreter.
+.PP
+Note that the argument strings are encoded in normalized UTF-8 since
+version 8.1 of Tcl.
+.PP
+\fIProc\fR must return an integer code that is expected to be one of
+\fBTCL_OK\fR, \fBTCL_ERROR\fR, \fBTCL_RETURN\fR, \fBTCL_BREAK\fR, or
+\fBTCL_CONTINUE\fR.  See the Tcl overview man page
+for details on what these codes mean.  Most normal commands will only
+return \fBTCL_OK\fR or \fBTCL_ERROR\fR.  In addition, \fIproc\fR must set
+the interpreter result;
+in the case of a \fBTCL_OK\fR return code this gives the result
+of the command, and in the case of \fBTCL_ERROR\fR it gives an error message.
+The \fBTcl_SetResult\fR procedure provides an easy interface for setting
+the return value;  for complete details on how the interpreter result
+field is managed, see the \fBTcl_Interp\fR man page.
+Before invoking a command procedure,
+\fBTcl_Eval\fR sets the interpreter result to point to an empty string,
+so simple commands can return an empty result by doing nothing at all.
+.PP
+The contents of the \fIargv\fR array belong to Tcl and are not
+guaranteed to persist once \fIproc\fR returns:  \fIproc\fR should
+not modify them, nor should it set the interpreter result to point
+anywhere within the \fIargv\fR values.
+Call \fBTcl_SetResult\fR with status \fBTCL_VOLATILE\fR if you want
+to return something from the \fIargv\fR array.
+.PP
+\fIDeleteProc\fR will be invoked when (if) \fIcmdName\fR is deleted. This can
+occur through a call to \fBTcl_DeleteCommand\fR or \fBTcl_DeleteInterp\fR,
+or by replacing \fIcmdName\fR in another call to \fBTcl_CreateCommand\fR.
+\fIDeleteProc\fR is invoked before the command is deleted, and gives the
+application an opportunity to release any structures associated
+with the command.  \fIDeleteProc\fR should have arguments and
+result that match the type \fBTcl_CmdDeleteProc\fR:
+.PP
+.CS
+typedef void \fBTcl_CmdDeleteProc\fR(
+        ClientData \fIclientData\fR);
+.CE
+.PP

+argument passed to \fBTcl_CreateCommand\fR.

+.BE
+.SH DESCRIPTION
+.PP
+\fBTcl_CreateFileHandler\fR arranges for \fIproc\fR to be
+invoked in the future whenever I/O becomes possible on a file
+or an exceptional condition exists for the file.  The file
+is indicated by \fIfd\fR, and the conditions of interest
+are indicated by \fImask\fR.  For example, if \fImask\fR
+is \fBTCL_READABLE\fR, \fIproc\fR will be called when
+the file is readable.
+The callback to \fIproc\fR is made by \fBTcl_DoOneEvent\fR, so
+\fBTcl_CreateFileHandler\fR is only useful in programs that dispatch
+events through \fBTcl_DoOneEvent\fR or through Tcl commands such
+as \fBvwait\fR.
+.PP
+\fIProc\fR should have arguments and result that match the
+type \fBTcl_FileProc\fR:
+.PP
+.CS
+typedef void \fBTcl_FileProc\fR(
+        ClientData \fIclientData\fR,
+        int \fImask\fR);
+.CE
+.PP
+The \fIclientData\fR parameter to \fIproc\fR is a copy
+of the \fIclientData\fR
+argument given to \fBTcl_CreateFileHandler\fR when the callback
+was created.  Typically, \fIclientData\fR points to a data
+structure containing application-specific information about
+the file.  \fIMask\fR is an integer mask indicating which
+of the requested conditions actually exists for the file;  it
+will contain a subset of the bits in the \fImask\fR argument
+to \fBTcl_CreateFileHandler\fR.
+.PP
+There may exist only one handler for a given file at a given time.
+If \fBTcl_CreateFileHandler\fR is called when a handler already
+exists for \fIfd\fR, then the new callback replaces the information
+that was previously recorded.
+.PP
+\fBTcl_DeleteFileHandler\fR may be called to delete the
+file handler for \fIfd\fR;  if no handler exists for the
+file given by \fIfd\fR then the procedure has no effect.
+.PP
+The purpose of file handlers is to enable an application to respond to
+events while waiting for files to become ready for I/O.  For this to work
+correctly, the application may need to use non-blocking I/O operations on
+the files for which handlers are declared.  Otherwise the application may
+block if it reads or writes too much data; while waiting for the I/O to
+complete the application will not be able to service other events. Use
+\fBTcl_SetChannelOption\fR with \fB\-blocking\fR to set the channel into
+blocking or nonblocking mode as required.
+.PP
+Note that these interfaces are only supported by the Unix
+implementation of the Tcl notifier.

+.BE
+.SH DESCRIPTION
+.PP
+\fBTcl_CreateInterp\fR creates a new interpreter structure and returns
+a token for it. The token is required in calls to most other Tcl
+procedures, such as \fBTcl_CreateCommand\fR, \fBTcl_Eval\fR, and
+\fBTcl_DeleteInterp\fR.  The token returned by \fBTcl_CreateInterp\fR
+may only be passed to Tcl routines called from the same thread as
+the original \fBTcl_CreateInterp\fR call.  It is not safe for multiple
+threads to pass the same token to Tcl's routines.
+The new interpreter is initialized with the built-in Tcl commands
+and with the variables documented in the \fBtclvars\fR manual page. To bind in
+additional commands, call \fBTcl_CreateCommand\fR.
+.PP
+\fBTcl_DeleteInterp\fR marks an interpreter as deleted; the interpreter
+will eventually be deleted when all calls to \fBTcl_Preserve\fR for it have
+been matched by calls to \fBTcl_Release\fR. At that time, all of the
+resources associated with it, including variables, procedures, and
+application-specific command bindings, will be deleted. After
+\fBTcl_DeleteInterp\fR returns any attempt to use \fBTcl_Eval\fR on the
+interpreter will fail and return \fBTCL_ERROR\fR. After the call to
+\fBTcl_DeleteInterp\fR it is safe to examine the interpreter's result,
+query or set the values of variables, define, undefine or retrieve
+procedures, and examine the runtime evaluation stack. See below, in the
+section \fBINTERPRETERS AND MEMORY MANAGEMENT\fR for details.
+.PP
+\fBTcl_InterpDeleted\fR returns nonzero if \fBTcl_DeleteInterp\fR was
+called with \fIinterp\fR as its argument; this indicates that the
+interpreter will eventually be deleted, when the last call to
+\fBTcl_Preserve\fR for it is matched by a call to \fBTcl_Release\fR. If
+nonzero is returned, further calls to \fBTcl_Eval\fR in this interpreter
+will return \fBTCL_ERROR\fR.
+.PP
+\fBTcl_InterpDeleted\fR is useful in deletion callbacks to distinguish
+between when only the memory the callback is responsible for is being
+deleted and when the whole interpreter is being deleted. In the former case
+the callback may recreate the data being deleted, but this would lead to an
+infinite loop if the interpreter were being deleted.
+.PP
+.VS 8.6
+\fBTcl_InterpActive\fR is useful for determining whether there is any
+execution of scripts ongoing in an interpreter, which is a useful piece of
+information when Tcl is embedded in a garbage-collected environment and it
+becomes necessary to determine whether the interpreter is a candidate for
+deletion. The function returns a true value if the interpreter has at least
+one active execution running inside it, and a false value otherwise.
+.VE 8.6
+.SH "INTERPRETERS AND MEMORY MANAGEMENT"
+.PP
+\fBTcl_DeleteInterp\fR can be called at any time on an interpreter that may
+be used by nested evaluations and C code in various extensions. Tcl
+implements a simple mechanism that allows callers to use interpreters
+without worrying about the interpreter being deleted in a nested call, and
+without requiring special code to protect the interpreter, in most cases.
+This mechanism ensures that nested uses of an interpreter can safely
+continue using it even after \fBTcl_DeleteInterp\fR is called.
+.PP
+The mechanism relies on matching up calls to \fBTcl_Preserve\fR with calls
+to \fBTcl_Release\fR. If \fBTcl_DeleteInterp\fR has been called, only when
+the last call to \fBTcl_Preserve\fR is matched by a call to
+\fBTcl_Release\fR, will the interpreter be freed. See the manual entry for
+\fBTcl_Preserve\fR for a description of these functions.
+.PP
+The rules for when the user of an interpreter must call \fBTcl_Preserve\fR
+and \fBTcl_Release\fR are simple:
+.TP
+\fBInterpreters Passed As Arguments\fR
+.
+Functions that are passed an interpreter as an argument can safely use the
+interpreter without any special protection. Thus, when you write an
+extension consisting of new Tcl commands, no special code is needed to
+protect interpreters received as arguments. This covers the majority of all
+uses.
+.TP
+\fBInterpreter Creation And Deletion\fR
+.
+When a new interpreter is created and used in a call to \fBTcl_Eval\fR,
+\fBTcl_VarEval\fR, \fBTcl_GlobalEval\fR, \fBTcl_SetVar\fR, or
+\fBTcl_GetVar\fR, a pair of calls to \fBTcl_Preserve\fR and
+\fBTcl_Release\fR should be wrapped around all uses of the interpreter.
+Remember that it is unsafe to use the interpreter once \fBTcl_Release\fR
+has been called. To ensure that the interpreter is properly deleted when
+it is no longer needed, call \fBTcl_InterpDeleted\fR to test if some other
+code already called \fBTcl_DeleteInterp\fR; if not, call
+\fBTcl_DeleteInterp\fR before calling \fBTcl_Release\fR in your own code.
+.TP
+\fBRetrieving An Interpreter From A Data Structure\fR
+.
+When an interpreter is retrieved from a data structure (e.g. the client
+data of a callback) for use in one of the evaluation functions
+(\fBTcl_Eval\fR, \fBTcl_VarEval\fR, \fBTcl_GlobalEval\fR, \fBTcl_EvalObjv\fR,
+etc.) or variable access functions (\fBTcl_SetVar\fR, \fBTcl_GetVar\fR,
+\fBTcl_SetVar2Ex\fR, etc.), a pair of
+calls to \fBTcl_Preserve\fR and \fBTcl_Release\fR should be wrapped around
+all uses of the interpreter; it is unsafe to reuse the interpreter once
+\fBTcl_Release\fR has been called. If an interpreter is stored inside a
+callback data structure, an appropriate deletion cleanup mechanism should
+be set up by the code that creates the data structure so that the
+interpreter is removed from the data structure (e.g. by setting the field
+to NULL) when the interpreter is deleted. Otherwise, you may be using an
+interpreter that has been freed and whose memory may already have been
+reused.
+.PP
+All uses of interpreters in Tcl and Tk have already been protected.
+Extension writers should ensure that their code also properly protects any
+additional interpreters used, as described above.
+.PP
+.VS 8.6
+Note that the protection mechanisms do not work well with conventional garbage
+collection systems. When in such a managed environment, \fBTcl_InterpActive\fR
+should be used to determine when an interpreter is a candidate for deletion
+due to inactivity.

+These functions are represented by commands in the namespace,
+\fBtcl::mathfunc\fR.  The \fBTcl_CreateMathFunc\fR function is
+an obsolete way for applications to add additional functions

+It should not be used by new applications, which should create
+math functions using \fBTcl_CreateObjCommand\fR to create a command
+in the \fBtcl::mathfunc\fR namespace.
+.PP

+\fIName\fR is the name of the function as it will appear in expressions.
+If \fIname\fR does not already exist in the \fB::tcl::mathfunc\fR

+If \fIname\fR does exist, then the existing function is replaced.
+\fINumArgs\fR and \fIargTypes\fR describe the arguments to the function.
+Each entry in the \fIargTypes\fR array must be
+one of \fBTCL_INT\fR, \fBTCL_DOUBLE\fR, \fBTCL_WIDE_INT\fR,
+or \fBTCL_EITHER\fR to indicate whether the corresponding argument must be an
+integer, a double-precision floating value, a wide (64-bit) integer,
+or any, respectively.
+.PP
+Whenever the function is invoked in an expression Tcl will invoke
+\fIproc\fR.  \fIProc\fR should have arguments and result that match
+the type \fBTcl_MathProc\fR:
+.PP
+.CS
+typedef int \fBTcl_MathProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        Tcl_Value *\fIargs\fR,
+        Tcl_Value *\fIresultPtr\fR);
+.CE
+.PP
+When \fIproc\fR is invoked the \fIclientData\fR and \fIinterp\fR
+arguments will be the same as those passed to \fBTcl_CreateMathFunc\fR.
+\fIArgs\fR will point to an array of \fInumArgs\fR Tcl_Value structures,
+which describe the actual arguments to the function:
+.PP
+.CS
+typedef struct Tcl_Value {
+    Tcl_ValueType \fItype\fR;
+    long \fIintValue\fR;
+    double \fIdoubleValue\fR;
+    Tcl_WideInt \fIwideValue\fR;
+} \fBTcl_Value\fR;
+.CE
+.PP
+The \fItype\fR field indicates the type of the argument and is
+one of \fBTCL_INT\fR, \fBTCL_DOUBLE\fR or \fBTCL_WIDE_INT\fR.
+It will match the \fIargTypes\fR value specified for the function unless
+the \fIargTypes\fR value was \fBTCL_EITHER\fR. Tcl converts
+the argument supplied in the expression to the type requested in
+\fIargTypes\fR, if that is necessary.
+Depending on the value of the \fItype\fR field, the \fIintValue\fR,
+\fIdoubleValue\fR or \fIwideValue\fR
+field will contain the actual value of the argument.
+.PP
+\fIProc\fR should compute its result and store it either as an integer
+in \fIresultPtr->intValue\fR or as a floating value in
+\fIresultPtr->doubleValue\fR.
+It should set also \fIresultPtr->type\fR to one of
+\fBTCL_INT\fR, \fBTCL_DOUBLE\fR or \fBTCL_WIDE_INT\fR
+to indicate which value was set.
+Under normal circumstances \fIproc\fR should return \fBTCL_OK\fR.
+If an error occurs while executing the function, \fIproc\fR should
+return \fBTCL_ERROR\fR and leave an error message in the interpreter's result.
+.PP
+\fBTcl_GetMathFuncInfo\fR retrieves the values associated with
+function \fIname\fR that were passed to a preceding
+\fBTcl_CreateMathFunc\fR call.  Normally, the return code is
+\fBTCL_OK\fR but if the named function does not exist, \fBTCL_ERROR\fR
+is returned and an error message is placed in the interpreter's
+result.
+.PP
+If an error did not occur, the array reference placed in the variable
+pointed to by \fIargTypesPtr\fR is newly allocated, and should be
+released by passing it to \fBTcl_Free\fR.  Some functions (the
+standard set implemented in the core, and those defined by placing
+commands in the \fBtcl::mathfunc\fR namespace) do not have
+argument type information; attempting to retrieve values for
+them causes a NULL to be stored in the variable pointed to by 
+\fIprocPtr\fR and the variable pointed to by \fIclientDataPtr\fR
+will not be modified.  The variable pointed to by \fInumArgsPointer\fR
+will contain -1, and no argument types will be stored in the variable
+pointed to by \fIargTypesPointer\fR.
+.PP
+\fBTcl_ListMathFuncs\fR returns a Tcl value containing a list of all
+the math functions defined in the interpreter whose name matches
+\fIpattern\fR.  The returned value has a reference count of zero.

+.SH DESCRIPTION
+.PP
+\fBTcl_CreateObjCommand\fR defines a new command in \fIinterp\fR
+and associates it with procedure \fIproc\fR
+such that whenever \fIname\fR is
+invoked as a Tcl command (e.g., via a call to \fBTcl_EvalObjEx\fR)
+the Tcl interpreter will call \fIproc\fR to process the command.
+.PP
+\fBTcl_CreateObjCommand\fR deletes any existing command
+\fIname\fR already associated with the interpreter
+(however see below for an exception where the existing command
+is not deleted).
+It returns a token that may be used to refer
+to the command in subsequent calls to \fBTcl_GetCommandName\fR.
+If \fIname\fR contains any \fB::\fR namespace qualifiers,
+then the command is added to the specified namespace;
+otherwise the command is added to the global namespace.
+If \fBTcl_CreateObjCommand\fR is called for an interpreter that is in
+the process of being deleted, then it does not create a new command
+and it returns NULL.
+\fIproc\fR should have arguments and result that match the type
+\fBTcl_ObjCmdProc\fR:
+.PP
+.CS
+typedef int \fBTcl_ObjCmdProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        int \fIobjc\fR,
+        Tcl_Obj *const \fIobjv\fR[]);
+.CE
+.PP
+When \fIproc\fR is invoked, the \fIclientData\fR and \fIinterp\fR parameters
+will be copies of the \fIclientData\fR and \fIinterp\fR arguments given to
+\fBTcl_CreateObjCommand\fR.  Typically, \fIclientData\fR points to an
+application-specific data structure that describes what to do when the
+command procedure is invoked. \fIObjc\fR and \fIobjv\fR describe the
+arguments to the command, \fIobjc\fR giving the number of argument values
+(including the command name) and \fIobjv\fR giving the values of the
+arguments.  The \fIobjv\fR array will contain \fIobjc\fR values, pointing to
+the argument values.  Unlike \fIargv\fR[\fIargv\fR] used in a
+string-based command procedure, \fIobjv\fR[\fIobjc\fR] will not contain NULL.
+.PP
+Additionally, when \fIproc\fR is invoked, it must not modify the contents
+of the \fIobjv\fR array by assigning new pointer values to any element of the
+array (for example, \fIobjv\fR[\fB2\fR] = \fBNULL\fR) because this will
+cause memory to be lost and the runtime stack to be corrupted.  The
+\fBconst\fR in the declaration of \fIobjv\fR will cause ANSI-compliant
+compilers to report any such attempted assignment as an error.  However,
+it is acceptable to modify the internal representation of any individual
+value argument.  For instance, the user may call
+\fBTcl_GetIntFromObj\fR on \fIobjv\fR[\fB2\fR] to obtain the integer
+representation of that value; that call may change the type of the value
+that \fIobjv\fR[\fB2\fR] points at, but will not change where
+\fIobjv\fR[\fB2\fR] points.
+.PP
+\fIproc\fR must return an integer code that is either \fBTCL_OK\fR,
+\fBTCL_ERROR\fR, \fBTCL_RETURN\fR, \fBTCL_BREAK\fR, or \fBTCL_CONTINUE\fR.
+See the Tcl overview man page
+for details on what these codes mean.  Most normal commands will only
+return \fBTCL_OK\fR or \fBTCL_ERROR\fR.
+In addition, if \fIproc\fR needs to return a non-empty result,
+it can call \fBTcl_SetObjResult\fR to set the interpreter's result.
+In the case of a \fBTCL_OK\fR return code this gives the result
+of the command,
+and in the case of \fBTCL_ERROR\fR this gives an error message.
+Before invoking a command procedure,
+\fBTcl_EvalObjEx\fR sets interpreter's result to
+point to a value representing an empty string, so simple
+commands can return an empty result by doing nothing at all.
+.PP
+The contents of the \fIobjv\fR array belong to Tcl and are not
+guaranteed to persist once \fIproc\fR returns: \fIproc\fR should
+not modify them.
+Call \fBTcl_SetObjResult\fR if you want
+to return something from the \fIobjv\fR array.
+.PP
+Ordinarily, \fBTcl_CreateObjCommand\fR deletes any existing command
+\fIname\fR already associated with the interpreter.
+However, if the existing command was created by a previous call to
+\fBTcl_CreateCommand\fR,
+\fBTcl_CreateObjCommand\fR does not delete the command
+but instead arranges for the Tcl interpreter to call the
+\fBTcl_ObjCmdProc\fR \fIproc\fR in the future.
+The old string-based \fBTcl_CmdProc\fR associated with the command
+is retained and its address can be obtained by subsequent 
+\fBTcl_GetCommandInfo\fR calls. This is done for backwards compatibility.
+.PP
+\fIDeleteProc\fR will be invoked when (if) \fIname\fR is deleted.
+This can occur through a call to \fBTcl_DeleteCommand\fR,
+\fBTcl_DeleteCommandFromToken\fR, or \fBTcl_DeleteInterp\fR,
+or by replacing \fIname\fR in another call to \fBTcl_CreateObjCommand\fR.
+\fIDeleteProc\fR is invoked before the command is deleted, and gives the
+application an opportunity to release any structures associated
+with the command.  \fIDeleteProc\fR should have arguments and
+result that match the type \fBTcl_CmdDeleteProc\fR:
+.PP
+.CS
+typedef void \fBTcl_CmdDeleteProc\fR(
+        ClientData \fIclientData\fR);
+.CE
+.PP
+The \fIclientData\fR argument will be the same as the \fIclientData\fR
+argument passed to \fBTcl_CreateObjCommand\fR.
+.PP
+\fBTcl_DeleteCommand\fR deletes a command from a command interpreter.
+Once the call completes, attempts to invoke \fIcmdName\fR in
+\fIinterp\fR will result in errors.
+If \fIcmdName\fR is not bound as a command in \fIinterp\fR then
+\fBTcl_DeleteCommand\fR does nothing and returns -1;  otherwise
+it returns 0.
+There are no restrictions on \fIcmdName\fR:  it may refer to
+a built-in command, an application-specific command, or a Tcl procedure.
+If \fIname\fR contains any \fB::\fR namespace qualifiers,
+the command is deleted from the specified namespace.
+.PP
+Given a token returned by \fBTcl_CreateObjCommand\fR,
+\fBTcl_DeleteCommandFromToken\fR deletes the command
+from a command interpreter.
+It will delete a command even if that command has been renamed.
+Once the call completes, attempts to invoke the command in
+\fIinterp\fR will result in errors.
+If the command corresponding to \fItoken\fR
+has already been deleted from \fIinterp\fR then
+\fBTcl_DeleteCommand\fR does nothing and returns -1;
+otherwise it returns 0.
+.PP
+\fBTcl_GetCommandInfo\fR checks to see whether its \fIcmdName\fR argument
+exists as a command in \fIinterp\fR.
+\fIcmdName\fR may include \fB::\fR namespace qualifiers
+to identify a command in a particular namespace.
+If the command is not found, then it returns 0.
+Otherwise it places information about the command
+in the \fBTcl_CmdInfo\fR structure
+pointed to by \fIinfoPtr\fR and returns 1.
+A \fBTcl_CmdInfo\fR structure has the following fields:
+.PP
+.CS
+typedef struct Tcl_CmdInfo {
+    int \fIisNativeObjectProc\fR;
+    Tcl_ObjCmdProc *\fIobjProc\fR;
+    ClientData \fIobjClientData\fR;
+    Tcl_CmdProc *\fIproc\fR;
+    ClientData \fIclientData\fR;
+    Tcl_CmdDeleteProc *\fIdeleteProc\fR;
+    ClientData \fIdeleteData\fR;
+    Tcl_Namespace *\fInamespacePtr\fR;
+} \fBTcl_CmdInfo\fR;
+.CE
+.PP
+The \fIisNativeObjectProc\fR field has the value 1
+if \fBTcl_CreateObjCommand\fR was called to register the command;
+it is 0 if only \fBTcl_CreateCommand\fR was called.
+It allows a program to determine whether it is faster to
+call \fIobjProc\fR or \fIproc\fR:
+\fIobjProc\fR is normally faster
+if \fIisNativeObjectProc\fR has the value 1.
+The fields \fIobjProc\fR and \fIobjClientData\fR
+have the same meaning as the \fIproc\fR and \fIclientData\fR
+arguments to \fBTcl_CreateObjCommand\fR;
+they hold information about the value-based command procedure
+that the Tcl interpreter calls to implement the command.
+The fields \fIproc\fR and \fIclientData\fR
+hold information about the string-based command procedure
+that implements the command.
+If \fBTcl_CreateCommand\fR was called for this command,
+this is the procedure passed to it;
+otherwise, this is a compatibility procedure
+registered by \fBTcl_CreateObjCommand\fR
+that simply calls the command's
+value-based procedure after converting its string arguments to Tcl values.
+The field \fIdeleteData\fR is the ClientData value
+to pass to \fIdeleteProc\fR;  it is normally the same as
+\fIclientData\fR but may be set independently using the
+\fBTcl_SetCommandInfo\fR procedure.
+The field \fInamespacePtr\fR holds a pointer to the
+Tcl_Namespace that contains the command.
+.PP
+\fBTcl_GetCommandInfoFromToken\fR is identical to
+\fBTcl_GetCommandInfo\fR except that it uses a command token returned
+from \fBTcl_CreateObjCommand\fR in place of the command name.  If the
+\fItoken\fR parameter is NULL, it returns 0; otherwise, it returns 1
+and fills in the structure designated by \fIinfoPtr\fR.
+.PP
+\fBTcl_SetCommandInfo\fR is used to modify the procedures and
+ClientData values associated with a command.
+Its \fIcmdName\fR argument is the name of a command in \fIinterp\fR.
+\fIcmdName\fR may include \fB::\fR namespace qualifiers
+to identify a command in a particular namespace.
+If this command does not exist then \fBTcl_SetCommandInfo\fR returns 0.
+Otherwise, it copies the information from \fI*infoPtr\fR to
+Tcl's internal structure for the command and returns 1.
+.PP
+\fBTcl_SetCommandInfoFromToken\fR is identical to
+\fBTcl_SetCommandInfo\fR except that it takes a command token as
+returned by \fBTcl_CreateObjCommand\fR instead of the command name.
+If the \fItoken\fR parameter is NULL, it returns 0.  Otherwise, it
+copies the information from \fI*infoPtr\fR to Tcl's internal structure
+for the command and returns 1.
+.PP
+Note that \fBTcl_SetCommandInfo\fR and
+\fBTcl_SetCommandInfoFromToken\fR both allow the ClientData for a
+command's deletion procedure to be given a different value than the
+ClientData for its command procedure.
+.PP
+Note that neither \fBTcl_SetCommandInfo\fR nor
+\fBTcl_SetCommandInfoFromToken\fR will change a command's namespace.
+Use \fBTcl_Eval\fR to call the \fBrename\fR command to do that.
+.PP
+\fBTcl_GetCommandName\fR provides a mechanism for tracking commands
+that have been renamed.
+Given a token returned by \fBTcl_CreateObjCommand\fR
+when the command was created, \fBTcl_GetCommandName\fR returns the
+string name of the command.  If the command has been renamed since it
+was created, then \fBTcl_GetCommandName\fR returns the current name.
+This name does not include any \fB::\fR namespace qualifiers.
+The command corresponding to \fItoken\fR must not have been deleted.
+The string returned by \fBTcl_GetCommandName\fR is in dynamic memory
+owned by Tcl and is only guaranteed to retain its value as long as the
+command is not deleted or renamed;  callers should copy the string if
+they need to keep it for a long time.
+.PP
+\fBTcl_GetCommandFullName\fR produces the fully qualified name
+of a command from a command token.  
+The name, including all namespace prefixes,
+is appended to the value specified by \fIobjPtr\fR.
+.PP
+\fBTcl_GetCommandFromObj\fR returns a token for the command
+specified by the name in a \fBTcl_Obj\fR.
+The command name is resolved relative to the current namespace.
+Returns NULL if the command is not found.

+.SH DESCRIPTION
+.PP
+These procedures are intended for access to the multiple interpreter
+facility from inside C programs. They enable managing multiple interpreters
+in a hierarchical relationship, and the management of aliases, commands
+that when invoked in one interpreter execute a command in another
+interpreter. The return value for those procedures that return an \fBint\fR
+is either \fBTCL_OK\fR or \fBTCL_ERROR\fR. If \fBTCL_ERROR\fR is returned
+then the \fBresult\fR field of the interpreter contains an error message.
+.PP
+\fBTcl_CreateSlave\fR creates a new interpreter as a slave of \fIinterp\fR.
+It also creates a slave command named \fIslaveName\fR in \fIinterp\fR which 
+allows \fIinterp\fR to manipulate the new slave. 
+If \fIisSafe\fR is zero, the command creates a trusted slave in which Tcl
+code has access to all the Tcl commands.
+If it is \fB1\fR, the command creates a
+.QW safe
+slave in which Tcl code has access only to set of Tcl commands defined as
+.QW "Safe Tcl" ;
+see the manual entry for the Tcl \fBinterp\fR command for details.
+If the creation of the new slave interpreter failed, \fBNULL\fR is returned.
+.PP
+\fBTcl_IsSafe\fR returns \fB1\fR if \fIinterp\fR is
+.QW safe
+(was created with the \fBTCL_SAFE_INTERPRETER\fR flag specified),
+\fB0\fR otherwise.
+.PP
+\fBTcl_MakeSafe\fR marks \fIinterp\fR as
+.QW safe ,
+so that future
+calls to \fBTcl_IsSafe\fR will return 1.  It also removes all known
+potentially-unsafe core functionality (both commands and variables)
+from \fIinterp\fR.  However, it cannot know what parts of an extension
+or application are safe and does not make any attempt to remove those
+parts, so safety is not guaranteed after calling \fBTcl_MakeSafe\fR.
+Callers will want to take care with their use of \fBTcl_MakeSafe\fR
+to avoid false claims of safety.  For many situations, \fBTcl_CreateSlave\fR
+may be a better choice, since it creates interpreters in a known-safe state.
+.PP
+\fBTcl_GetSlave\fR returns a pointer to a slave interpreter of
+\fIinterp\fR. The slave interpreter is identified by \fIslaveName\fR.
+If no such slave interpreter exists, \fBNULL\fR is returned.
+.PP
+\fBTcl_GetMaster\fR returns a pointer to the master interpreter of
+\fIinterp\fR. If \fIinterp\fR has no master (it is a
+top-level interpreter) then \fBNULL\fR is returned.
+.PP
+\fBTcl_GetInterpPath\fR sets the \fIresult\fR field in \fIaskingInterp\fR
+to the relative path between \fIaskingInterp\fR and \fIslaveInterp\fR;
+\fIslaveInterp\fR must be a slave of \fIaskingInterp\fR. If the computation
+of the relative path succeeds, \fBTCL_OK\fR is returned, else
+\fBTCL_ERROR\fR is returned and the \fIresult\fR field in
+\fIaskingInterp\fR contains the error message.
+.PP
+\fBTcl_CreateAlias\fR creates a command named \fIslaveCmd\fR in
+\fIslaveInterp\fR that when invoked, will cause the command \fItargetCmd\fR
+to be invoked in \fItargetInterp\fR. The arguments specified by the strings
+contained in \fIargv\fR are always prepended to any arguments supplied in the
+invocation of \fIslaveCmd\fR and passed to \fItargetCmd\fR.
+This operation returns \fBTCL_OK\fR if it succeeds, or \fBTCL_ERROR\fR if
+it fails; in that case, an error message is left in the value result
+of \fIslaveInterp\fR.
+Note that there are no restrictions on the ancestry relationship (as
+created by \fBTcl_CreateSlave\fR) between \fIslaveInterp\fR and
+\fItargetInterp\fR. Any two interpreters can be used, without any
+restrictions on how they are related.
+.PP
+\fBTcl_CreateAliasObj\fR is similar to \fBTcl_CreateAlias\fR except 
+that it takes a vector of values to pass as additional arguments instead
+of a vector of strings.
+.PP
+\fBTcl_GetAlias\fR returns information about an alias \fIaliasName\fR
+in \fIinterp\fR. Any of the result fields can be \fBNULL\fR, in
+which case the corresponding datum is not returned. If a result field is
+non\-\fBNULL\fR, the address indicated is set to the corresponding datum.
+For example, if \fItargetNamePtr\fR is non\-\fBNULL\fR it is set to a
+pointer to the string containing the name of the target command.
+.PP
+\fBTcl_GetAliasObj\fR is similar to \fBTcl_GetAlias\fR except that it
+returns a pointer to a vector of Tcl_Obj structures instead of a vector of
+strings.
+.PP
+\fBTcl_ExposeCommand\fR moves the command named \fIhiddenCmdName\fR from
+the set of hidden commands to the set of exposed commands, putting
+it under the name
+\fIcmdName\fR. 
+\fIHiddenCmdName\fR must be the name of an existing hidden
+command, or the operation will return \fBTCL_ERROR\fR and leave an error
+message in the \fIresult\fR field in \fIinterp\fR.
+If an exposed command named \fIcmdName\fR already exists,
+the operation returns \fBTCL_ERROR\fR and leaves an error message in the
+value result of \fIinterp\fR.
+If the operation succeeds, it returns \fBTCL_OK\fR.
+After executing this command, attempts to use \fIcmdName\fR in a call to
+\fBTcl_Eval\fR or with the Tcl \fBeval\fR command will again succeed.
+.PP
+\fBTcl_HideCommand\fR moves the command named \fIcmdName\fR from the set of
+exposed commands to the set of hidden commands, under the name
+\fIhiddenCmdName\fR.
+\fICmdName\fR must be the name of an existing exposed
+command, or the operation will return \fBTCL_ERROR\fR and leave an error
+message in the value result of \fIinterp\fR.
+Currently both \fIcmdName\fR and \fIhiddenCmdName\fR must not contain
+namespace qualifiers, or the operation will return \fBTCL_ERROR\fR and
+leave an error message in the value result of \fIinterp\fR.
+The \fICmdName\fR will be looked up in the global namespace, and not
+relative to the current namespace, even if the current namespace is not the
+global one.
+If a hidden command whose name is \fIhiddenCmdName\fR already
+exists, the operation also returns \fBTCL_ERROR\fR and the \fIresult\fR
+field in \fIinterp\fR contains an error message.
+If the operation succeeds, it returns \fBTCL_OK\fR.
+After executing this command, attempts to use \fIcmdName\fR in a call to

+.SH DESCRIPTION
+.PP
+\fBTcl_CreateTimerHandler\fR arranges for \fIproc\fR to be
+invoked at a time \fImilliseconds\fR milliseconds in the
+future.
+The callback to \fIproc\fR will be made by \fBTcl_DoOneEvent\fR,
+so \fBTcl_CreateTimerHandler\fR is only useful in programs that
+dispatch events through \fBTcl_DoOneEvent\fR or through Tcl commands
+such as \fBvwait\fR.
+The call to \fIproc\fR may not be made at the exact time given by
+\fImilliseconds\fR:  it will be made at the next opportunity
+after that time.  For example, if \fBTcl_DoOneEvent\fR is not
+called until long after the time has elapsed, or if there
+are other pending events to process before the call to
+\fIproc\fR, then the call to \fIproc\fR will be delayed.
+.PP
+\fIProc\fR should have arguments and return value that match
+the type \fBTcl_TimerProc\fR:
+.PP
+.CS
+typedef void \fBTcl_TimerProc\fR(
+        ClientData \fIclientData\fR);
+.CE
+.PP
+The \fIclientData\fR parameter to \fIproc\fR is a
+copy of the \fIclientData\fR argument given to
+\fBTcl_CreateTimerHandler\fR when the callback
+was created.  Typically, \fIclientData\fR points to a data
+structure containing application-specific information about
+what to do in \fIproc\fR.
+.PP
+\fBTcl_DeleteTimerHandler\fR may be called to delete a
+previously created timer handler.  It deletes the handler
+indicated by \fItoken\fR so that no call to \fIproc\fR
+will be made;  if that handler no longer exists
+(e.g. because the time period has already elapsed and \fIproc\fR
+has been invoked then \fBTcl_DeleteTimerHandler\fR does nothing.
+The tokens returned by \fBTcl_CreateTimerHandler\fR never have
+a value of NULL, so if NULL is passed to \fBTcl_DeleteTimerHandler\fR
+then the procedure does nothing.

+to \fBTcl_CreateTrace\fR).
+.BE
+.SH DESCRIPTION
+.PP
+\fBTcl_CreateObjTrace\fR arranges for command tracing.  After it is
+called, \fIobjProc\fR will be invoked before the Tcl interpreter calls
+any command procedure when evaluating commands in \fIinterp\fR.
+The return value from \fBTcl_CreateObjTrace\fR is a token for the trace,
+which may be passed to \fBTcl_DeleteTrace\fR to remove the trace.
+There may be many traces in effect simultaneously for the same
+interpreter.
+.PP
+\fIobjProc\fR should have arguments and result that match the type,
+\fBTcl_CmdObjTraceProc\fR:
+.PP
+.CS
+typedef int \fBTcl_CmdObjTraceProc\fR( 
+        \fBClientData\fR \fIclientData\fR,
+        \fBTcl_Interp\fR* \fIinterp\fR,
+        int \fIlevel\fR,
+        const char *\fIcommand\fR,
+        \fBTcl_Command\fR \fIcommandToken\fR,
+        int \fIobjc\fR,
+        \fBTcl_Obj\fR *const \fIobjv\fR[]);
+.CE
+.PP
+The \fIclientData\fR and \fIinterp\fR parameters are copies of the
+corresponding arguments given to \fBTcl_CreateTrace\fR.
+\fIClientData\fR typically points to an application-specific data
+structure that describes what to do when \fIobjProc\fR is invoked.  The
+\fIlevel\fR parameter gives the nesting level of the command (1 for
+top-level commands passed to \fBTcl_Eval\fR by the application, 2 for
+the next-level commands passed to \fBTcl_Eval\fR as part of parsing or
+interpreting level-1 commands, and so on). The \fIcommand\fR parameter
+points to a string containing the text of the command, before any
+argument substitution.  The \fIcommandToken\fR parameter is a Tcl
+command token that identifies the command to be invoked.  The token
+may be passed to \fBTcl_GetCommandName\fR,
+\fBTcl_GetCommandInfoFromToken\fR, or \fBTcl_SetCommandInfoFromToken\fR to
+manipulate the definition of the command. The \fIobjc\fR and \fIobjv\fR
+parameters designate the final parameter count and parameter vector
+that will be passed to the command, and have had all substitutions
+performed.
+.PP
+The \fIobjProc\fR callback is expected to return a standard Tcl status
+return code.  If this code is \fBTCL_OK\fR (the normal case), then
+the Tcl interpreter will invoke the command.  Any other return code
+is treated as if the command returned that status, and the command is
+\fInot\fR invoked.
+.PP
+The \fIobjProc\fR callback must not modify \fIobjv\fR in any way.  It
+is, however, permissible to change the command by calling
+\fBTcl_SetCommandTokenInfo\fR prior to returning.  Any such change
+takes effect immediately, and the command is invoked with the new
+information.
+.PP
+Tracing will only occur for commands at nesting level less than
+or equal to the \fIlevel\fR parameter (i.e. the \fIlevel\fR
+parameter to \fIobjProc\fR will always be less than or equal to the
+\fIlevel\fR parameter to \fBTcl_CreateTrace\fR).
+.PP
+Tracing has a significant effect on runtime performance because it
+causes the bytecode compiler to refrain from generating in-line code
+for Tcl commands such as \fBif\fR and \fBwhile\fR in order that they
+may be traced.  If traces for the built-in commands are not required,
+the \fIflags\fR parameter may be set to the constant value
+\fBTCL_ALLOW_INLINE_COMPILATION\fR.  In this case, traces on built-in
+commands may or may not result in trace callbacks, depending on the
+state of the interpreter, but run-time performance will be improved
+significantly.  (This functionality is desirable, for example, when
+using \fBTcl_CreateObjTrace\fR to implement an execution time
+profiler.)
+.PP
+Calls to \fIobjProc\fR will be made by the Tcl parser immediately before
+it calls the command procedure for the command (\fIcmdProc\fR).  This
+occurs after argument parsing and substitution, so tracing for
+substituted commands occurs before tracing of the commands
+containing the substitutions.  If there is a syntax error in a
+command, or if there is no command procedure associated with a
+command name, then no tracing will occur for that command.  If a
+string passed to Tcl_Eval contains multiple commands (bracketed, or
+on different lines) then multiple calls to \fIobjProc\fR will occur,
+one for each command.
+.PP
+\fBTcl_DeleteTrace\fR removes a trace, so that no future calls will be
+made to the procedure associated with the trace.  After \fBTcl_DeleteTrace\fR
+returns, the caller should never again use the \fItrace\fR token.
+.PP
+When \fBTcl_DeleteTrace\fR is called, the interpreter invokes the
+\fIdeleteProc\fR that was passed as a parameter to
+\fBTcl_CreateObjTrace\fR.  The \fIdeleteProc\fR must match the type,
+\fBTcl_CmdObjTraceDeleteProc\fR:
+.PP
+.CS
+typedef void \fBTcl_CmdObjTraceDeleteProc\fR( 
+        \fBClientData\fR \fIclientData\fR);
+.CE
+.PP
+The \fIclientData\fR parameter will be the same as the
+\fIclientData\fR parameter that was originally passed to
+\fBTcl_CreateObjTrace\fR.
+.PP
+\fBTcl_CreateTrace\fR is an alternative interface for command tracing,
+\fInot recommended for new applications\fR.  It is provided for backward
+compatibility with code that was developed for older versions of the
+Tcl interpreter.  It is similar to \fBTcl_CreateObjTrace\fR, except
+that its \fIproc\fR parameter should have arguments and result that
+match the type \fBTcl_CmdTraceProc\fR:
+.PP
+.CS
+typedef void \fBTcl_CmdTraceProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        int \fIlevel\fR,
+        char *\fIcommand\fR,
+        Tcl_CmdProc *\fIcmdProc\fR,
+        ClientData \fIcmdClientData\fR,
+        int \fIargc\fR,
+        const char *\fIargv\fR[]);
+.CE
+.PP
+The parameters to the \fIproc\fR callback are similar to those of the
+\fIobjProc\fR callback above. The \fIcommandToken\fR is
+replaced with \fIcmdProc\fR, a pointer to the (string-based) command
+procedure that will be invoked; and \fIcmdClientData\fR, the client
+data that will be passed to the procedure.  The \fIobjc\fR parameter
+is replaced with an \fIargv\fR parameter, that gives the arguments to
+the command as character strings.
+\fIProc\fR must not modify the \fIcommand\fR or \fIargv\fR strings.
+.PP
+If a trace created with \fBTcl_CreateTrace\fR is in effect, inline
+compilation of Tcl commands such as \fBif\fR and \fBwhile\fR is always
+disabled.  There is no notification when a trace created with
+\fBTcl_CreateTrace\fR is deleted.
+There is no way to be notified when the trace created by
+\fBTcl_CreateTrace\fR is deleted.  There is no way for the \fIproc\fR
+associated with a call to \fBTcl_CreateTrace\fR to abort execution of
+\fIcommand\fR.

+
+.SH DESCRIPTION
+.PP
+Dynamic strings provide a mechanism for building up arbitrarily long
+strings by gradually appending information.  If the dynamic string is
+short then there will be no memory allocation overhead;  as the string
+gets larger, additional space will be allocated as needed.
+.PP
+\fBTcl_DStringInit\fR initializes a dynamic string to zero length.
+The Tcl_DString structure must have been allocated by the caller.
+No assumptions are made about the current state of the structure;
+anything already in it is discarded.
+If the structure has been used previously, \fBTcl_DStringFree\fR should
+be called first to free up any memory allocated for the old
+string.
+.PP
+\fBTcl_DStringAppend\fR adds new information to a dynamic string,
+allocating more memory for the string if needed.
+If \fIlength\fR is less than zero then everything in \fIbytes\fR
+is appended to the dynamic string;  otherwise \fIlength\fR
+specifies the number of bytes to append.
+\fBTcl_DStringAppend\fR returns a pointer to the characters of
+the new string.  The string can also be retrieved from the
+\fIstring\fR field of the Tcl_DString structure.
+.PP
+\fBTcl_DStringAppendElement\fR is similar to \fBTcl_DStringAppend\fR
+except that it does not take a \fIlength\fR argument (it appends
+all of \fIelement\fR) and it converts the string to a proper list element
+before appending.
+\fBTcl_DStringAppendElement\fR adds a separator space before the
+new list element unless the new list element is the first in a
+list or sub-list (i.e. either the current string is empty, or it
+contains the single character
+.QW { ,
+or the last two characters of the current string are
+.QW " {" ).
+\fBTcl_DStringAppendElement\fR returns a pointer to the
+characters of the new string.
+.PP
+\fBTcl_DStringStartSublist\fR and \fBTcl_DStringEndSublist\fR can be
+used to create nested lists.
+To append a list element that is itself a sublist, first
+call \fBTcl_DStringStartSublist\fR, then call \fBTcl_DStringAppendElement\fR
+for each of the elements in the sublist, then call
+\fBTcl_DStringEndSublist\fR to end the sublist.
+\fBTcl_DStringStartSublist\fR appends a space character if needed,
+followed by an open brace;  \fBTcl_DStringEndSublist\fR appends
+a close brace.
+Lists can be nested to any depth.
+.PP
+\fBTcl_DStringLength\fR is a macro that returns the current length
+of a dynamic string (not including the terminating null character).
+\fBTcl_DStringValue\fR is a  macro that returns a pointer to the
+current contents of a dynamic string.
+.PP
+.PP
+\fBTcl_DStringSetLength\fR changes the length of a dynamic string.
+If \fInewLength\fR is less than the string's current length, then
+the string is truncated.
+If \fInewLength\fR is greater than the string's current length,
+then the string will become longer and new space will be allocated
+for the string if needed.
+However, \fBTcl_DStringSetLength\fR will not initialize the new
+space except to provide a terminating null character;  it is up to the
+caller to fill in the new space.
+\fBTcl_DStringSetLength\fR does not free up the string's storage space
+even if the string is truncated to zero length, so \fBTcl_DStringFree\fR
+will still need to be called.
+.PP
+\fBTcl_DStringTrunc\fR changes the length of a dynamic string.
+This procedure is now deprecated.  \fBTcl_DStringSetLength\fR  should
+be used instead.
+.PP
+\fBTcl_DStringFree\fR should be called when you are finished using
+the string.  It frees up any memory that was allocated for the string
+and reinitializes the string's value to an empty string.
+.PP
+\fBTcl_DStringResult\fR sets the result of \fIinterp\fR to the value of
+the dynamic string given by \fIdsPtr\fR.  It does this by moving
+a pointer from \fIdsPtr\fR to the interpreter's result.
+This saves the cost of allocating new memory and copying the string.
+\fBTcl_DStringResult\fR also reinitializes the dynamic string to
+an empty string.
+.PP
+\fBTcl_DStringGetResult\fR does the opposite of \fBTcl_DStringResult\fR.
+It sets the value of \fIdsPtr\fR to the result of \fIinterp\fR and
+it clears \fIinterp\fR's result.
+If possible it does this by moving a pointer rather than by copying
+the string.

+\fBTcl_DetachPids\fR and \fBTcl_ReapDetachedProcs\fR provide a
+mechanism for managing subprocesses that are running in background.
+These procedures are needed because the parent of a process must
+eventually invoke the \fBwaitpid\fR kernel call (or one of a few other
+similar kernel calls) to wait for the child to exit.  Until the
+parent waits for the child, the child's state cannot be completely
+reclaimed by the system.  If a parent continually creates children
+and doesn't wait on them, the system's process table will eventually
+overflow, even if all the children have exited.
+.PP
+\fBTcl_DetachPids\fR may be called to ask Tcl to take responsibility
+for one or more processes whose process ids are contained in the
+\fIpidPtr\fR array passed as argument.  The caller presumably
+has started these processes running in background and does not
+want to have to deal with them again.
+.PP
+\fBTcl_ReapDetachedProcs\fR invokes the \fBwaitpid\fR kernel call
+on each of the background processes so that its state can be cleaned
+up if it has exited.  If the process has not exited yet,
+\fBTcl_ReapDetachedProcs\fR does not wait for it to exit;  it will check again
+the next time it is invoked.
+Tcl automatically calls \fBTcl_ReapDetachedProcs\fR each time the
+\fBexec\fR command is executed, so in most cases it is not necessary
+for any code outside of Tcl to invoke \fBTcl_ReapDetachedProcs\fR.
+However, if you call \fBTcl_DetachPids\fR in situations where the
+\fBexec\fR command may never get executed, you may wish to call
+\fBTcl_ReapDetachedProcs\fR from time to time so that background
+processes can be cleaned up.
+.PP
+\fBTcl_WaitPid\fR is a thin wrapper around the facilities provided by
+the operating system to wait on the end of a spawned process and to
+check a whether spawned process is still running. It is used by
+\fBTcl_ReapDetachedProcs\fR and the channel system to portably access
+the operating system.

+.SH DESCRIPTION
+.PP
+Tcl dictionary values have an internal representation that supports
+efficient mapping from keys to values and which guarantees that the
+particular ordering of keys within the dictionary remains the same
+modulo any keys being deleted (which removes them from the order) or
+added (which adds them to the end of the order). If reinterpreted as a
+list, the values at the even-valued indices in the list will be the
+keys of the dictionary, and each will be followed (in the odd-valued
+index) by the value associated with that key.
+.PP
+The procedures described in this man page are used to
+create, modify, index, and iterate over dictionary values from C code.
+.PP
+\fBTcl_NewDictObj\fR creates a new, empty dictionary value.  The
+string representation of the value will be invalid, and the reference
+count of the value will be zero.
+.PP
+\fBTcl_DictObjGet\fR looks up the given key within the given
+dictionary and writes a pointer to the value associated with that key
+into the variable pointed to by \fIvaluePtrPtr\fR, or a NULL if the
+key has no mapping within the dictionary.  The result of this
+procedure is \fBTCL_OK\fR, or \fBTCL_ERROR\fR if the \fIdictPtr\fR cannot be
+converted to a dictionary.
+.PP
+\fBTcl_DictObjPut\fR updates the given dictionary so that the given
+key maps to the given value; any key may exist at most once in any
+particular dictionary.  The dictionary must not be shared, but the key
+and value may be.  This procedure may increase the reference count of
+both key and value if it proves necessary to store them.  Neither key
+nor value should be NULL.  The result of this procedure is \fBTCL_OK\fR, or
+\fBTCL_ERROR\fR if the \fIdictPtr\fR cannot be converted to a dictionary.
+.PP
+\fBTcl_DictObjRemove\fR updates the given dictionary so that the given
+key has no mapping to any value.  The dictionary must not be shared,
+but the key may be.  The key actually stored in the dictionary will
+have its reference count decremented if it was present.  It is not an
+error if the key did not previously exist.  The result of this
+procedure is \fBTCL_OK\fR, or \fBTCL_ERROR\fR if the \fIdictPtr\fR cannot be
+converted to a dictionary.
+.PP
+\fBTcl_DictObjSize\fR updates the given variable with the number of
+key/value pairs currently in the given dictionary. The result of this
+procedure is \fBTCL_OK\fR, or \fBTCL_ERROR\fR if the \fIdictPtr\fR cannot be
+converted to a dictionary.
+.PP
+\fBTcl_DictObjFirst\fR commences an iteration across all the key/value
+pairs in the given dictionary, placing the key and value in the
+variables pointed to by the \fIkeyPtrPtr\fR and \fIvaluePtrPtr\fR
+arguments (which may be NULL to indicate that the caller is
+uninterested in they key or variable respectively.)  The next
+key/value pair in the dictionary may be retrieved with
+\fBTcl_DictObjNext\fR.  Concurrent updates of the dictionary's
+internal representation will not modify the iteration processing
+unless the dictionary is unshared, when this will trigger premature
+termination of the iteration instead (which Tcl scripts cannot trigger
+via the \fBdict\fR command.)  The \fIsearchPtr\fR argument points to a
+piece of context that is used to identify which particular iteration
+is being performed, and is initialized by the call to
+\fBTcl_DictObjFirst\fR.  The \fIdonePtr\fR argument points to a
+variable that is updated to be zero of there are further key/value
+pairs to be iterated over, or non-zero if the iteration is complete.
+The order of iteration is implementation-defined.  If the
+\fIdictPtr\fR argument cannot be converted to a dictionary,
+\fBTcl_DictObjFirst\fR returns \fBTCL_ERROR\fR and the iteration is not
+commenced, and otherwise it returns \fBTCL_OK\fR.
+.PP
+When \fBTcl_DictObjFirst\fR is called upon a dictionary, a lock is placed on
+the dictionary to enable that dictionary to be iterated over safely without
+regard for whether the dictionary is modified during the iteration. Because of
+this, once the iteration over a dictionary's keys has finished (whether
+because all values have been iterated over as indicated by the variable
+indicated by the \fIdonePtr\fR argument being set to one, or because no
+further values are required) the \fBTcl_DictObjDone\fR function must be called
+with the same \fIsearchPtr\fR as was passed to \fBTcl_DictObjFirst\fR so that
+the internal locks can be released. Once a particular \fIsearchPtr\fR is
+passed to \fBTcl_DictObjDone\fR, passing it to \fBTcl_DictObjNext\fR (without
+first initializing it with \fBTcl_DictObjFirst\fR) will result in no values
+being produced and the variable pointed to by \fIdonePtr\fR being set to one.
+It is safe to call \fBTcl_DictObjDone\fR multiple times on the same
+\fIsearchPtr\fR for each call to \fBTcl_DictObjFirst\fR.
+.PP
+The procedures \fBTcl_DictObjPutKeyList\fR and
+\fBTcl_DictObjRemoveKeyList\fR are the close analogues of
+\fBTcl_DictObjPut\fR and \fBTcl_DictObjRemove\fR respectively, except
+that instead of working with a single dictionary, they are designed to
+operate on a nested tree of dictionaries, with inner dictionaries
+stored as values inside outer dictionaries.  The \fIkeyc\fR and
+\fIkeyv\fR arguments specify a list of keys (with outermost keys
+first) that acts as a path to the key/value pair to be affected.  Note
+that there is no corresponding operation for reading a value for a
+path as this is easy to construct from repeated use of
+\fBTcl_DictObjGet\fR. With \fBTcl_DictObjPutKeyList\fR, nested
+dictionaries are created for non-terminal keys where they do not
+already exist. With \fBTcl_DictObjRemoveKeyList\fR, all non-terminal
+keys must exist and have dictionaries as their values.
+.SH EXAMPLE
+Using the dictionary iteration interface to search determine if there
+is a key that maps to itself:
+.PP
+.CS
+Tcl_DictSearch search;
+Tcl_Obj *key, *value;
+int done;
+
+/*
+ * Assume interp and objPtr are parameters.  This is the
+ * idiomatic way to start an iteration over the dictionary; it
+ * sets a lock on the internal representation that ensures that
+ * there are no concurrent modification issues when normal
+ * reference count management is also used.  The lock is
+ * released automatically when the loop is finished, but must
+ * be released manually when an exceptional exit from the loop
+ * is performed. However it is safe to try to release the lock
+ * even if we've finished iterating over the loop.
+ */
+if (\fBTcl_DictObjFirst\fR(interp, objPtr, &search,
+        &key, &value, &done) != TCL_OK) {
+    return TCL_ERROR;
+}
+for (; !done ; \fBTcl_DictObjNext\fR(&search, &key, &value, &done)) {
+    /*
+     * Note that strcmp() is not a good way of comparing
+     * values and is just used here for demonstration
+     * purposes.
+     */
+    if (!strcmp(Tcl_GetString(key), Tcl_GetString(value))) {
+        break;
+    }

+.SH ARGUMENTS
+.AS int flags
+.AP int flags in
+This parameter is normally zero.  It may be an OR-ed combination
+of any of the following flag bits:  
+\fBTCL_WINDOW_EVENTS\fR, \fBTCL_FILE_EVENTS\fR,
+\fBTCL_TIMER_EVENTS\fR, \fBTCL_IDLE_EVENTS\fR, \fBTCL_ALL_EVENTS\fR,
+or \fBTCL_DONT_WAIT\fR.
+.BE
+
+.SH DESCRIPTION
+.PP
+This procedure is the entry point to Tcl's event loop; it is responsible for
+waiting for events and dispatching event handlers created with
+procedures such as \fBTk_CreateEventHandler\fR, \fBTcl_CreateFileHandler\fR,
+\fBTcl_CreateTimerHandler\fR, and \fBTcl_DoWhenIdle\fR.
+\fBTcl_DoOneEvent\fR checks to see if
+events are already present on the Tcl event queue; if so,
+it calls the handler(s) for the first (oldest) event, removes it from
+the queue, and returns.
+If there are no events ready to be handled, then \fBTcl_DoOneEvent\fR
+checks for new events from all possible sources.
+If any are found, it puts all of them on Tcl's event queue, calls
+handlers for the first event on the queue, and returns.
+If no events are found, \fBTcl_DoOneEvent\fR checks for \fBTcl_DoWhenIdle\fR
+callbacks; if any are found, it invokes all of them and returns.
+Finally, if no events or idle callbacks have been found, then
+\fBTcl_DoOneEvent\fR sleeps until an event occurs; then it adds any 
+new events to the Tcl event queue, calls handlers for the first event,
+and returns.
+The normal return value is 1 to signify that some event
+was processed (see below for other alternatives).
+.PP
+If the \fIflags\fR argument to \fBTcl_DoOneEvent\fR is non-zero,
+it restricts the kinds of events that will be processed by
+\fBTcl_DoOneEvent\fR.
+\fIFlags\fR may be an OR-ed combination of any of the following bits:
+.TP 27
+\fBTCL_WINDOW_EVENTS\fR \-
+Process window system events.
+.TP 27
+\fBTCL_FILE_EVENTS\fR \-
+Process file events.
+.TP 27
+\fBTCL_TIMER_EVENTS\fR \-
+Process timer events.
+.TP 27
+\fBTCL_IDLE_EVENTS\fR \-
+Process idle callbacks.
+.TP 27
+\fBTCL_ALL_EVENTS\fR \-
+Process all kinds of events:  equivalent to OR-ing together all of the
+above flags or specifying none of them.
+.TP 27
+\fBTCL_DONT_WAIT\fR \-
+Do not sleep:  process only events that are ready at the time of the
+call.
+.LP
+If any of the flags \fBTCL_WINDOW_EVENTS\fR, \fBTCL_FILE_EVENTS\fR,
+\fBTCL_TIMER_EVENTS\fR, or \fBTCL_IDLE_EVENTS\fR is set, then the only
+events that will be considered are those for which flags are set.
+Setting none of these flags is equivalent to the value
+\fBTCL_ALL_EVENTS\fR, which causes all event types to be processed.
+If an application has defined additional event sources with
+\fBTcl_CreateEventSource\fR, then additional \fIflag\fR values
+may also be valid, depending on those event sources.
+.PP
+The \fBTCL_DONT_WAIT\fR flag causes \fBTcl_DoOneEvent\fR not to put
+the process to sleep:  it will check for events but if none are found
+then it returns immediately with a return value of 0 to indicate
+that no work was done.
+\fBTcl_DoOneEvent\fR will also return 0 without doing anything if
+the only alternative is to block forever (this can happen, for example,
+if \fIflags\fR is \fBTCL_IDLE_EVENTS\fR and there are no
+\fBTcl_DoWhenIdle\fR callbacks pending, or if no event handlers or
+timer handlers exist).
+.PP
+\fBTcl_DoOneEvent\fR may be invoked recursively.  For example,
+it is possible to invoke \fBTcl_DoOneEvent\fR recursively
+from a handler called by \fBTcl_DoOneEvent\fR.  This sort
+of operation is useful in some modal situations, such
+as when a
+notification dialog has been popped up and an application wishes to
+wait for the user to click a button in the dialog before
+doing anything else.

+Arbitrary one-word value to pass to \fIproc\fR.
+.BE
+.SH DESCRIPTION
+.PP
+\fBTcl_DoWhenIdle\fR arranges for \fIproc\fR to be invoked
+when the application becomes idle.  The application is
+considered to be idle when \fBTcl_DoOneEvent\fR has been
+called, could not find any events to handle, and is about
+to go to sleep waiting for an event to occur.  At this
+point all pending \fBTcl_DoWhenIdle\fR handlers are
+invoked.  For each call to \fBTcl_DoWhenIdle\fR there will
+be a single call to \fIproc\fR;  after \fIproc\fR is
+invoked the handler is automatically removed.
+\fBTcl_DoWhenIdle\fR is only usable in programs that
+use \fBTcl_DoOneEvent\fR to dispatch events.
+.PP
+\fIProc\fR should have arguments and result that match the
+type \fBTcl_IdleProc\fR:
+.PP
+.CS
+typedef void \fBTcl_IdleProc\fR(
+        ClientData \fIclientData\fR);
+.CE
+.PP
+The \fIclientData\fR parameter to \fIproc\fR is a copy of the \fIclientData\fR
+argument given to \fBTcl_DoWhenIdle\fR.  Typically, \fIclientData\fR
+points to a data structure containing application-specific information about
+what \fIproc\fR should do.
+.PP
+\fBTcl_CancelIdleCall\fR
+may be used to cancel one or more previous
+calls to \fBTcl_DoWhenIdle\fR:  if there is a \fBTcl_DoWhenIdle\fR
+handler registered for \fIproc\fR and \fIclientData\fR, then it
+is removed without invoking it.  If there is more than one
+handler on the idle list that refers to \fIproc\fR and \fIclientData\fR,
+all of the handlers are removed.  If no existing handlers match
+\fIproc\fR and \fIclientData\fR then nothing happens.
+.PP
+\fBTcl_DoWhenIdle\fR is most useful in situations where
+(a) a piece of work will have to be done but (b) it is
+possible that something will happen in the near future
+that will change what has to be done or require something
+different to be done.  \fBTcl_DoWhenIdle\fR allows the
+actual work to be deferred until all pending events have
+been processed.  At this point the exact work to be done
+will presumably be known and it can be done exactly once.
+.PP
+For example, \fBTcl_DoWhenIdle\fR might be used by an editor
+to defer display updates until all pending commands have
+been processed.  Without this feature, redundant redisplays
+might occur in some situations, such as the processing of
+a command file.
+.SH BUGS
+.PP
+At present it is not safe for an idle callback to reschedule itself
+continuously.  This will interact badly with certain features of Tk
+that attempt to wait for all idle callbacks to complete.  If you would
+like for an idle callback to reschedule itself continuously, it is
+better to use a timer handler with a zero timeout period.

+.SH ARGUMENTS
+.AS Tcl_Interp *fileName
+.AP Tcl_Interp *interp in
+Tcl interpreter in which to add commands.
+.AP "const char" *fileName in
+For \fBTcl_DumpActiveMemory\fR, name of the file to which memory
+information will be written.  For \fBTcl_ValidateAllMemory\fR, name of
+the file from which the call is being made (normally \fB__FILE__\fR).
+.AP int line in
+Line number at which the call to \fBTcl_ValidateAllMemory\fR is made
+(normally \fB__LINE__\fR).
+.BE
+
+.SH DESCRIPTION
+These functions provide access to Tcl memory debugging information.
+They are only functional when Tcl has been compiled with
+\fBTCL_MEM_DEBUG\fR defined at compile-time.  When \fBTCL_MEM_DEBUG\fR
+is not defined, these functions are all no-ops.
+.PP 
+\fBTcl_DumpActiveMemory\fR will output a list of all currently
+allocated memory to the specified file.  The information output for
+each allocated block of memory is:  starting and ending addresses
+(excluding guard zone), size, source file where \fBckalloc\fR was
+called to allocate the block and line number in that file.  It is
+especially useful to call \fBTcl_DumpActiveMemory\fR after the Tcl
+interpreter has been deleted.
+.PP
+\fBTcl_InitMemory\fR adds the Tcl \fBmemory\fR command to the
+interpreter given by \fIinterp\fR.  \fBTcl_InitMemory\fR is called
+by \fBTcl_Main\fR.
+.PP
+\fBTcl_ValidateAllMemory\fR forces a validation of the guard zones of
+all currently allocated blocks of memory.  Normally validation of a
+block occurs when its freed, unless full validation is enabled, in
+which case validation of all blocks occurs when \fBckalloc\fR and
+\fBckfree\fR are called.  This function forces the validation to occur
+at any point.

+.SH INTRODUCTION
+.PP
+These routines convert between Tcl's internal character representation,
+UTF-8, and character representations used by various operating systems or
+file systems, such as Unicode, ASCII, or Shift-JIS.  When operating on
+strings, such as such as obtaining the names of files or displaying
+characters using international fonts, the strings must be translated into
+one or possibly multiple formats that the various system calls can use.  For
+instance, on a Japanese Unix workstation, a user might obtain a filename
+represented in the EUC-JP file encoding and then translate the characters to
+the jisx0208 font encoding in order to display the filename in a Tk widget.
+The purpose of the encoding package is to help bridge the translation gap.
+UTF-8 provides an intermediate staging ground for all the various
+encodings.  In the example above, text would be translated into UTF-8 from
+whatever file encoding the operating system is using.  Then it would be
+translated from UTF-8 into whatever font encoding the display routines
+require.
+.PP
+Some basic encodings are compiled into Tcl.  Others can be defined by the
+user or dynamically loaded from encoding files in a
+platform-independent manner.
+.SH DESCRIPTION
+.PP
+\fBTcl_GetEncoding\fR finds an encoding given its \fIname\fR.  The name may
+refer to a built-in Tcl encoding, a user-defined encoding registered by
+calling \fBTcl_CreateEncoding\fR, or a dynamically-loadable encoding
+file.  The return value is a token that represents the encoding and can be
+used in subsequent calls to procedures such as \fBTcl_GetEncodingName\fR,
+\fBTcl_FreeEncoding\fR, and \fBTcl_UtfToExternal\fR.  If the name did not
+refer to any known or loadable encoding, NULL is returned and an error
+message is returned in \fIinterp\fR.
+.PP
+The encoding package maintains a database of all encodings currently in use.
+The first time \fIname\fR is seen, \fBTcl_GetEncoding\fR returns an
+encoding with a reference count of 1.  If the same \fIname\fR is requested
+further times, then the reference count for that encoding is incremented
+without the overhead of allocating a new encoding and all its associated
+data structures.  
+.PP
+When an \fIencoding\fR is no longer needed, \fBTcl_FreeEncoding\fR
+should be called to release it.  When an \fIencoding\fR is no longer in use
+anywhere (i.e., it has been freed as many times as it has been gotten)
+\fBTcl_FreeEncoding\fR will release all storage the encoding was using
+and delete it from the database. 
+.PP
+\fBTcl_GetEncodingFromObj\fR treats the string representation of
+\fIobjPtr\fR as an encoding name, and finds an encoding with that
+name, just as \fBTcl_GetEncoding\fR does. When an encoding is found,
+it is cached within the \fBobjPtr\fR value for future reference, the
+\fBTcl_Encoding\fR token is written to the storage pointed to by
+\fIencodingPtr\fR, and the value \fBTCL_OK\fR is returned. If no such
+encoding is found, the value \fBTCL_ERROR\fR is returned, and no
+writing to \fB*\fR\fIencodingPtr\fR takes place. Just as with
+\fBTcl_GetEncoding\fR, the caller should call \fBTcl_FreeEncoding\fR
+on the resulting encoding token when that token will no longer be
+used.
+.PP
+\fBTcl_ExternalToUtfDString\fR converts a source buffer \fIsrc\fR from the
+specified \fIencoding\fR into UTF-8.  The converted bytes are stored in 
+\fIdstPtr\fR, which is then null-terminated.  The caller should eventually
+call \fBTcl_DStringFree\fR to free any information stored in \fIdstPtr\fR.
+When converting, if any of the characters in the source buffer cannot be
+represented in the target encoding, a default fallback character will be
+used.  The return value is a pointer to the value stored in the DString.
+.PP
+\fBTcl_ExternalToUtf\fR converts a source buffer \fIsrc\fR from the specified
+\fIencoding\fR into UTF-8.  Up to \fIsrcLen\fR bytes are converted from the
+source buffer and up to \fIdstLen\fR converted bytes are stored in \fIdst\fR.
+In all cases, \fI*srcReadPtr\fR is filled with the number of bytes that were
+successfully converted from \fIsrc\fR and \fI*dstWrotePtr\fR is filled with
+the corresponding number of bytes that were stored in \fIdst\fR.  The return
+value is one of the following:
+.RS
+.IP \fBTCL_OK\fR 29
+All bytes of \fIsrc\fR were converted.
+.IP \fBTCL_CONVERT_NOSPACE\fR 29
+The destination buffer was not large enough for all of the converted data; as
+many characters as could fit were converted though.
+.IP \fBTCL_CONVERT_MULTIBYTE\fR 29
+The last few bytes in the source buffer were the beginning of a multibyte
+sequence, but more bytes were needed to complete this sequence.  A
+subsequent call to the conversion routine should pass a buffer containing
+the unconverted bytes that remained in \fIsrc\fR plus some further bytes
+from the source stream to properly convert the formerly split-up multibyte
+sequence.  
+.IP \fBTCL_CONVERT_SYNTAX\fR 29
+The source buffer contained an invalid character sequence.  This may occur
+if the input stream has been damaged or if the input encoding method was
+misidentified.
+.IP \fBTCL_CONVERT_UNKNOWN\fR 29
+The source buffer contained a character that could not be represented in
+the target encoding and \fBTCL_ENCODING_STOPONERROR\fR was specified.  
+.RE
+.LP
+\fBTcl_UtfToExternalDString\fR converts a source buffer \fIsrc\fR from UTF-8 
+into the specified \fIencoding\fR.  The converted bytes are stored in
+\fIdstPtr\fR, which is then terminated with the appropriate encoding-specific
+null.  The caller should eventually call \fBTcl_DStringFree\fR to free any
+information stored in \fIdstPtr\fR.  When converting, if any of the
+characters in the source buffer cannot be represented in the target
+encoding, a default fallback character will be used.  The return value is
+a pointer to the value stored in the DString.
+.PP
+\fBTcl_UtfToExternal\fR converts a source buffer \fIsrc\fR from UTF-8 into
+the specified \fIencoding\fR.  Up to \fIsrcLen\fR bytes are converted from
+the source buffer and up to \fIdstLen\fR converted bytes are stored in
+\fIdst\fR.  In all cases, \fI*srcReadPtr\fR is filled with the number of
+bytes that were successfully converted from \fIsrc\fR and \fI*dstWrotePtr\fR
+is filled with the corresponding number of bytes that were stored in
+\fIdst\fR.  The return values are the same as the return values for
+\fBTcl_ExternalToUtf\fR.
+.PP
+\fBTcl_WinUtfToTChar\fR and \fBTcl_WinTCharToUtf\fR are
+Windows-only convenience
+functions for converting between UTF-8 and Windows strings.  On Windows 95
+(as with the Unix operating system),
+all strings exchanged between Tcl and the operating system are
+.QW "char"
+based.  On Windows NT, some strings exchanged between Tcl and the
+operating system are
+.QW "char"
+oriented while others are in Unicode.  By
+convention, in Windows a TCHAR is a character in the ANSI code page
+on Windows 95 and a Unicode character on Windows NT.
+.PP
+If you planned to use the same
+.QW "char"
+based interfaces on both Windows
+95 and Windows NT, you could use \fBTcl_UtfToExternal\fR and
+\fBTcl_ExternalToUtf\fR (or their \fBTcl_DString\fR equivalents) with an
+encoding of NULL (the current system encoding).  On the other hand,
+if you planned to use the Unicode interface when running on Windows NT
+and the
+.QW "char"
+interfaces when running on Windows 95, you would have
+to perform the following type of test over and over in your program
+(as represented in pseudo-code):
+.PP
+.CS
+if (running NT) {
+    encoding <- Tcl_GetEncoding("unicode");
+    nativeBuffer <- Tcl_UtfToExternal(encoding, utfBuffer);
+    Tcl_FreeEncoding(encoding);
+} else {
+    nativeBuffer <- Tcl_UtfToExternal(NULL, utfBuffer);
+}
+.CE
+.PP
+\fBTcl_WinUtfToTChar\fR and \fBTcl_WinTCharToUtf\fR automatically
+handle this test and use the proper encoding based on the current
+operating system.  \fBTcl_WinUtfToTChar\fR returns a pointer to
+a TCHAR string, and \fBTcl_WinTCharToUtf\fR expects a TCHAR string
+pointer as the \fIsrc\fR string.  Otherwise, these functions
+behave identically to \fBTcl_UtfToExternalDString\fR and
+\fBTcl_ExternalToUtfDString\fR.
+.PP
+\fBTcl_GetEncodingName\fR is roughly the inverse of \fBTcl_GetEncoding\fR.
+Given an \fIencoding\fR, the return value is the \fIname\fR argument that
+was used to create the encoding.  The string returned by 
+\fBTcl_GetEncodingName\fR is only guaranteed to persist until the
+\fIencoding\fR is deleted.  The caller must not modify this string.
+.PP
+\fBTcl_SetSystemEncoding\fR sets the default encoding that should be used
+whenever the user passes a NULL value for the \fIencoding\fR argument to
+any of the other encoding functions.  If \fIname\fR is NULL, the system
+encoding is reset to the default system encoding, \fBbinary\fR.  If the
+name did not refer to any known or loadable encoding, \fBTCL_ERROR\fR is
+returned and an error message is left in \fIinterp\fR.  Otherwise, this
+procedure increments the reference count of the new system encoding,
+decrements the reference count of the old system encoding, and returns
+\fBTCL_OK\fR.
+.PP
+\fBTcl_GetEncodingNameFromEnvironment\fR provides a means for the Tcl
+library to report the encoding name it believes to be the correct one
+to use as the system encoding, based on system calls and examination of
+the environment suitable for the platform.  It accepts \fIbufPtr\fR,
+a pointer to an uninitialized or freed \fBTcl_DString\fR and writes
+the encoding name to it.  The \fBTcl_DStringValue\fR is returned.
+.PP
+\fBTcl_GetEncodingNames\fR sets the \fIinterp\fR result to a list
+consisting of the names of all the encodings that are currently defined
+or can be dynamically loaded, searching the encoding path specified by
+\fBTcl_SetDefaultEncodingDir\fR.  This procedure does not ensure that the
+dynamically-loadable encoding files contain valid data, but merely that they
+exist.
+.PP
+\fBTcl_CreateEncoding\fR defines a new encoding and registers the C
+procedures that are called back to convert between the encoding and
+UTF-8.  Encodings created by \fBTcl_CreateEncoding\fR are thereafter
+visible in the database used by \fBTcl_GetEncoding\fR.  Just as with the
+\fBTcl_GetEncoding\fR procedure, the return value is a token that
+represents the encoding and can be used in subsequent calls to other
+encoding functions.  \fBTcl_CreateEncoding\fR returns an encoding with a
+reference count of 1. If an encoding with the specified \fIname\fR
+already exists, then its entry in the database is replaced with the new
+encoding; the token for the old encoding will remain valid and continue
+to behave as before, but users of the new token will now call the new
+encoding procedures.  
+.PP
+The \fItypePtr\fR argument to \fBTcl_CreateEncoding\fR contains information 
+about the name of the encoding and the procedures that will be called to
+convert between this encoding and UTF-8.  It is defined as follows:
+.PP
+.CS
+typedef struct Tcl_EncodingType {
+    const char *\fIencodingName\fR;
+    Tcl_EncodingConvertProc *\fItoUtfProc\fR;
+    Tcl_EncodingConvertProc *\fIfromUtfProc\fR;
+    Tcl_EncodingFreeProc *\fIfreeProc\fR;
+    ClientData \fIclientData\fR;
+    int \fInullSize\fR;
+} \fBTcl_EncodingType\fR;  
+.CE
+.PP
+The \fIencodingName\fR provides a string name for the encoding, by
+which it can be referred in other procedures such as
+\fBTcl_GetEncoding\fR.  The \fItoUtfProc\fR refers to a callback
+procedure to invoke to convert text from this encoding into UTF-8.
+The \fIfromUtfProc\fR refers to a callback procedure to invoke to
+convert text from UTF-8 into this encoding.  The \fIfreeProc\fR refers
+to a callback procedure to invoke when this encoding is deleted.  The
+\fIfreeProc\fR field may be NULL.  The \fIclientData\fR contains an
+arbitrary one-word value passed to \fItoUtfProc\fR, \fIfromUtfProc\fR,
+and \fIfreeProc\fR whenever they are called.  Typically, this is a
+pointer to a data structure containing encoding-specific information
+that can be used by the callback procedures.  For instance, two very
+similar encodings such as \fBascii\fR and \fBmacRoman\fR may use the
+same callback procedure, but use different values of \fIclientData\fR
+to control its behavior.  The \fInullSize\fR specifies the number of
+zero bytes that signify end-of-string in this encoding.  It must be
+\fB1\fR (for single-byte or multi-byte encodings like ASCII or
+Shift-JIS) or \fB2\fR (for double-byte encodings like Unicode).
+Constant-sized encodings with 3 or more bytes per character (such as
+CNS11643) are not accepted.
+.PP
+The callback procedures \fItoUtfProc\fR and \fIfromUtfProc\fR should match the
+type \fBTcl_EncodingConvertProc\fR:
+.PP
+.CS
+typedef int \fBTcl_EncodingConvertProc\fR(
+        ClientData \fIclientData\fR,
+        const char *\fIsrc\fR, 
+        int \fIsrcLen\fR, 
+        int \fIflags\fR, 
+        Tcl_EncodingState *\fIstatePtr\fR,
+        char *\fIdst\fR, 
+        int \fIdstLen\fR, 
+        int *\fIsrcReadPtr\fR,
+        int *\fIdstWrotePtr\fR,
+        int *\fIdstCharsPtr\fR);
+.CE
+.PP
+The \fItoUtfProc\fR and \fIfromUtfProc\fR procedures are called by the
+\fBTcl_ExternalToUtf\fR or \fBTcl_UtfToExternal\fR family of functions to
+perform the actual conversion.  The \fIclientData\fR parameter to these
+procedures is the same as the \fIclientData\fR field specified to
+\fBTcl_CreateEncoding\fR when the encoding was created.  The remaining
+arguments to the callback procedures are the same as the arguments,
+documented at the top, to \fBTcl_ExternalToUtf\fR or
+\fBTcl_UtfToExternal\fR, with the following exceptions.  If the
+\fIsrcLen\fR argument to one of those high-level functions is negative,
+the value passed to the callback procedure will be the appropriate
+encoding-specific string length of \fIsrc\fR.  If any of the \fIsrcReadPtr\fR, 
+\fIdstWrotePtr\fR, or \fIdstCharsPtr\fR arguments to one of the high-level
+functions is NULL, the corresponding value passed to the callback
+procedure will be a non-NULL location.
+.PP
+The callback procedure \fIfreeProc\fR, if non-NULL, should match the type 
+\fBTcl_EncodingFreeProc\fR:
+.PP
+.CS
+typedef void \fBTcl_EncodingFreeProc\fR(
+        ClientData \fIclientData\fR);
+.CE
+.PP
+This \fIfreeProc\fR function is called when the encoding is deleted.  The
+\fIclientData\fR parameter is the same as the \fIclientData\fR field
+specified to \fBTcl_CreateEncoding\fR when the encoding was created.  
+.PP
+\fBTcl_GetEncodingSearchPath\fR and \fBTcl_SetEncodingSearchPath\fR
+are called to access and set the list of filesystem directories searched
+for encoding data files.  
+.PP
+The value returned by \fBTcl_GetEncodingSearchPath\fR
+is the value stored by the last successful call to
+\fBTcl_SetEncodingSearchPath\fR.  If no calls to
+\fBTcl_SetEncodingSearchPath\fR have occurred, Tcl will compute an initial
+value based on the environment.  There is one encoding search path for the
+entire process, shared by all threads in the process.
+.PP
+\fBTcl_SetEncodingSearchPath\fR stores \fIsearchPath\fR and returns
+\fBTCL_OK\fR, unless \fIsearchPath\fR is not a valid Tcl list, which
+causes \fBTCL_ERROR\fR to be returned.  The elements of \fIsearchPath\fR
+are not verified as existing readable filesystem directories.  When
+searching for encoding data files takes place, and non-existent or
+non-readable filesystem directories on the \fIsearchPath\fR are silently
+ignored.
+.PP
+\fBTcl_GetDefaultEncodingDir\fR and \fBTcl_SetDefaultEncodingDir\fR
+are obsolete interfaces best replaced with calls to
+\fBTcl_GetEncodingSearchPath\fR and \fBTcl_SetEncodingSearchPath\fR.
+They are called to access and set the first element of the \fIsearchPath\fR
+list.  Since Tcl searches \fIsearchPath\fR for encoding data files in
+list order, these routines establish the
+.QW default
+directory in which to find encoding data files.
+.SH "ENCODING FILES"
+Space would prohibit precompiling into Tcl every possible encoding
+algorithm, so many encodings are stored on disk as dynamically-loadable
+encoding files.  This behavior also allows the user to create additional
+encoding files that can be loaded using the same mechanism.  These
+encoding files contain information about the tables and/or escape
+sequences used to map between an external encoding and Unicode.  The
+external encoding may consist of single-byte, multi-byte, or double-byte
+characters.  
+.PP
+Each dynamically-loadable encoding is represented as a text file.  The
+initial line of the file, beginning with a
+.QW #
+symbol, is a comment
+that provides a human-readable description of the file.  The next line
+identifies the type of encoding file.  It can be one of the following
+letters:
+.IP "[1] \fBS\fR"
+A single-byte encoding, where one character is always one byte long in the
+encoding.  An example is \fBiso8859-1\fR, used by many European languages.
+.IP "[2] \fBD\fR"
+A double-byte encoding, where one character is always two bytes long in the
+encoding.  An example is \fBbig5\fR, used for Chinese text.
+.IP "[3] \fBM\fR"
+A multi-byte encoding, where one character may be either one or two bytes long.
+Certain bytes are lead bytes, indicating that another byte must follow

+The third line of the file is three numbers.  The first number is the
+fallback character (in base 16) to use when converting from UTF-8 to this
+encoding.  The second number is a \fB1\fR if this file represents the
+encoding for a symbol font, or \fB0\fR otherwise.  The last number (in base
+10) is how many pages of data follow.  
+.PP
+Subsequent lines in the example above are pages that describe how to map
+from the encoding into 2-byte Unicode.  The first line in a page identifies
+the page number.  Following it are 256 double-byte numbers, arranged as 16
+rows of 16 numbers.  Given a character in the encoding, the high byte of
+that character is used to select which page, and the low byte of that
+character is used as an index to select one of the double-byte numbers in
+that page \- the value obtained being the corresponding Unicode character.
+By examination of the example above, one can see that the characters 0x7E
+and 0x8163 in \fBshiftjis\fR map to 203E and 2026 in Unicode, respectively.
+.PP
+Following the first page will be all the other pages, each in the same
+format as the first: one number identifying the page followed by 256
+double-byte Unicode characters.  If a character in the encoding maps to the
+Unicode character 0000, it means that the character does not actually exist.
+If all characters on a page would map to 0000, that page can be omitted.
+.PP
+Case [4] is the escape-sequence encoding file.  The lines in an this type of
+file are in the same format as this example taken from the \fBiso2022-jp\fR
+encoding:
+.PP
+.CS

+jis0212		\ex1b$(D
+gb2312		\ex1b$A
+ksc5601		\ex1b$(C
+.CE
+.PP
+In the file, the first column represents an option and the second column
+is the associated value.  \fBinit\fR is a string to emit or expect before
+the first character is converted, while \fBfinal\fR is a string to emit
+or expect after the last character.  All other options are names of
+table-based encodings; the associated value is the escape-sequence that
+marks that encoding.  Tcl syntax is used for the values; in the above
+example, for instance,
+.QW \fB{}\fR
+represents the empty string and
+.QW \fB\ex1b\fR
+represents character 27.
+.PP
+When \fBTcl_GetEncoding\fR encounters an encoding \fIname\fR that has not
+been loaded, it attempts to load an encoding file called \fIname\fB.enc\fR
+from the \fBencoding\fR subdirectory of each directory that Tcl searches
+for its script library.  If the encoding file exists, but is
+malformed, an error message will be left in \fIinterp\fR.

+.BE
+.SH DESCRIPTION
+An ensemble is a command, bound to some namespace, which consists of a
+collection of subcommands implemented by other Tcl commands. The first
+argument to the ensemble command is always interpreted as a selector
+that states what subcommand to execute.
+.PP
+Ensembles are created using \fBTcl_CreateEnsemble\fR, which takes four
+arguments: the interpreter to work within, the name of the ensemble to
+create, the namespace within the interpreter to bind the ensemble to,
+and the default set of ensemble flags. The result of the function is
+the command token for the ensemble, which may be used to further
+configure the ensemble using the API described below in
+\fBENSEMBLE PROPERTIES\fR.
+.PP
+Given the name of an ensemble command, the token for that command may
+be retrieved using \fBTcl_FindEnsemble\fR. If the given command name
+(in \fIcmdNameObj\fR) does not refer to an ensemble command, the
+result of the function is NULL and (if the \fBTCL_LEAVE_ERR_MSG\fR bit is
+set in \fIflags\fR) an error message is left in the interpreter
+result.
+.PP
+A command token may be checked to see if it refers to an ensemble
+using \fBTcl_IsEnsemble\fR. This returns 1 if the token refers to an
+ensemble, or 0 otherwise.
+.SS "ENSEMBLE PROPERTIES"
+Every ensemble has four read-write properties and a read-only
+property. The properties are:
+.TP
+\fBflags\fR (read-write)
+.
+The set of flags for the ensemble, expressed as a
+bit-field. Currently, the only public flag is \fBTCL_ENSEMBLE_PREFIX\fR
+which is set when unambiguous prefixes of subcommands are permitted to
+be resolved to implementations as well as exact matches. The flags may
+be read and written using \fBTcl_GetEnsembleFlags\fR and
+\fBTcl_SetEnsembleFlags\fR respectively. The result of both of those
+functions is a Tcl result code (\fBTCL_OK\fR, or \fBTCL_ERROR\fR if
+the token does not refer to an ensemble).
+.TP
+\fBmapping dictionary\fR (read-write)
+.
+A dictionary containing a mapping from subcommand names to lists of
+words to use as a command prefix (replacing the first two words of the
+command which are the ensemble command itself and the subcommand
+name), or NULL if every subcommand is to be mapped to the command with
+the same unqualified name in the ensemble's bound namespace. Defaults
+to NULL. May be read and written using
+\fBTcl_GetEnsembleMappingDict\fR and \fBTcl_SetEnsembleMappingDict\fR
+respectively. The result of both of those functions is a Tcl result
+code (\fBTCL_OK\fR, or \fBTCL_ERROR\fR if the token does not refer to an
+ensemble) and the dictionary obtained from
+\fBTcl_GetEnsembleMappingDict\fR should always be treated as immutable
+even if it is unshared.
+All command names in prefixes set via \fBTcl_SetEnsembleMappingDict\fR
+must be fully qualified.
+.TP
+\fBformal pre-subcommand parameter list\fR (read-write)
+.VS 8.6
+A list of formal parameter names (the names only being used when generating
+error messages) that come at invocation of the ensemble between the name of
+the ensemble and the subcommand argument. NULL (the default) is equivalent to
+the empty list. May be read and written using
+\fBTcl_GetEnsembleParameterList\fR and \fBTcl_SetEnsembleParameterList\fR
+respectively. The result of both of those functions is a Tcl result code
+(\fBTCL_OK\fR, or \fBTCL_ERROR\fR if the token does not refer to an
+ensemble) and the
+dictionary obtained from \fBTcl_GetEnsembleParameterList\fR should always be
+treated as immutable even if it is unshared.
+.VE 8.6
+.TP
+\fBsubcommand list\fR (read-write)
+.
+A list of all the subcommand names for the ensemble, or NULL if this
+is to be derived from either the keys of the mapping dictionary (see
+above) or (if that is also NULL) from the set of commands exported by
+the bound namespace. May be read and written using
+\fBTcl_GetEnsembleSubcommandList\fR and
+\fBTcl_SetEnsembleSubcommandList\fR respectively. The result of both
+of those functions is a Tcl result code (\fBTCL_OK\fR, or
+\fBTCL_ERROR\fR if the 
+token does not refer to an ensemble) and the list obtained from
+\fBTcl_GetEnsembleSubcommandList\fR should always be treated as
+immutable even if it is unshared.
+.TP
+\fBunknown subcommand handler command prefix\fR (read-write)
+.
+A list of words to prepend on the front of any subcommand when the
+subcommand is unknown to the ensemble (according to the current prefix
+handling rule); see the \fBnamespace ensemble\fR command for more
+details. If NULL, the default behavior \- generate a suitable error
+message \- will be used when an unknown subcommand is encountered. May
+be read and written using \fBTcl_GetEnsembleUnknownHandler\fR and
+\fBTcl_SetEnsembleUnknownHandler\fR respectively. The result of both
+functions is a Tcl result code (\fBTCL_OK\fR, or \fBTCL_ERROR\fR if
+the token does
+not refer to an ensemble) and the list obtained from
+\fBTcl_GetEnsembleUnknownHandler\fR should always be treated as
+immutable even if it is unshared.
+.TP
+\fBbound namespace\fR (read-only)
+.
+The namespace to which the ensemble is bound; when the namespace is
+deleted, so too will the ensemble, and this namespace is also the
+namespace whose list of exported commands is used if both the mapping
+dictionary and the subcommand list properties are NULL. May be read
+using \fBTcl_GetEnsembleNamespace\fR which returns a Tcl result code
+(\fBTCL_OK\fR, or \fBTCL_ERROR\fR if the token does not refer to an ensemble).

+.SH DESCRIPTION
+.PP
+The procedures described here are invoked to execute Tcl scripts in
+various forms.
+\fBTcl_EvalObjEx\fR is the core procedure and is used by many of the others.
+It executes the commands in the script stored in \fIobjPtr\fR
+until either an error occurs or the end of the script is reached.
+If this is the first time \fIobjPtr\fR has been executed,
+its commands are compiled into bytecode instructions
+which are then executed.  The
+bytecodes are saved in \fIobjPtr\fR so that the compilation step
+can be skipped if the value is evaluated again in the future.
+.PP
+The return value from \fBTcl_EvalObjEx\fR (and all the other procedures
+described here) is a Tcl completion code with
+one of the values \fBTCL_OK\fR, \fBTCL_ERROR\fR, \fBTCL_RETURN\fR,
+\fBTCL_BREAK\fR, or \fBTCL_CONTINUE\fR, or possibly some other
+integer value originating in an extension.
+In addition, a result value or error message is left in \fIinterp\fR's
+result; it can be retrieved using \fBTcl_GetObjResult\fR.
+.PP
+\fBTcl_EvalFile\fR reads the file given by \fIfileName\fR and evaluates
+its contents as a Tcl script.  It returns the same information as
+\fBTcl_EvalObjEx\fR.
+If the file could not be read then a Tcl error is returned to describe
+why the file could not be read.
+The eofchar for files is
+.QW \e32
+(^Z) for all platforms. If you require a
+.QW ^Z
+in code for string comparison, you can use
+.QW \e032
+or
+.QW \eu001a ,
+which will be safely substituted by the Tcl interpreter into
+.QW ^Z .
+.PP
+\fBTcl_EvalObjv\fR executes a single pre-parsed command instead of a
+script.  The \fIobjc\fR and \fIobjv\fR arguments contain the values
+of the words for the Tcl command, one word in each value in
+\fIobjv\fR.  \fBTcl_EvalObjv\fR evaluates the command and returns
+a completion code and result just like \fBTcl_EvalObjEx\fR.
+The caller of \fBTcl_EvalObjv\fR has to manage the reference count of the
+elements of \fIobjv\fR, insuring that the values are valid until
+\fBTcl_EvalObjv\fR returns.  
+.PP
+\fBTcl_Eval\fR is similar to \fBTcl_EvalObjEx\fR except that the script to
+be executed is supplied as a string instead of a value and no compilation
+occurs.  The string should be a proper UTF-8 string as converted by
+\fBTcl_ExternalToUtfDString\fR or \fBTcl_ExternalToUtf\fR when it is known
+to possibly contain upper ASCII characters whose possible combinations
+might be a UTF-8 special code.  The string is parsed and executed directly
+(using \fBTcl_EvalObjv\fR) instead of compiling it and executing the
+bytecodes.  In situations where it is known that the script will never be
+executed again, \fBTcl_Eval\fR may be faster than \fBTcl_EvalObjEx\fR.
+ \fBTcl_Eval\fR returns a completion code and result just like 
+\fBTcl_EvalObjEx\fR.  Note: for backward compatibility with versions before
+Tcl 8.0, \fBTcl_Eval\fR copies the value result in \fIinterp\fR to
+\fIinterp->result\fR (use is deprecated) where it can be accessed directly.
+ This makes \fBTcl_Eval\fR somewhat slower than \fBTcl_EvalEx\fR, which
+does not do the copy.
+.PP
+\fBTcl_EvalEx\fR is an extended version of \fBTcl_Eval\fR that takes
+additional arguments \fInumBytes\fR and \fIflags\fR.  For the
+efficiency reason given above, \fBTcl_EvalEx\fR is generally preferred
+over \fBTcl_Eval\fR.
+.PP
+\fBTcl_GlobalEval\fR and \fBTcl_GlobalEvalObj\fR are older procedures
+that are now deprecated.  They are similar to \fBTcl_EvalEx\fR and
+\fBTcl_EvalObjEx\fR except that the script is evaluated in the global
+namespace and its variable context consists of global variables only
+(it ignores any Tcl procedures that are active).  These functions are
+equivalent to using the \fBTCL_EVAL_GLOBAL\fR flag (see below).
+.PP
+\fBTcl_VarEval\fR takes any number of string arguments
+of any length, concatenates them into a single string,
+then calls \fBTcl_Eval\fR to execute that string as a Tcl command.
+It returns the result of the command and also modifies
+\fIinterp->result\fR in the same way as \fBTcl_Eval\fR.
+The last argument to \fBTcl_VarEval\fR must be NULL to indicate the end
+of arguments.  \fBTcl_VarEval\fR is now deprecated.
+.PP
+\fBTcl_VarEvalVA\fR is the same as \fBTcl_VarEval\fR except that
+instead of taking a variable number of arguments it takes an argument
+list. Like \fBTcl_VarEval\fR, \fBTcl_VarEvalVA\fR is deprecated.
+
+.SH "FLAG BITS"
+.PP
+Any ORed combination of the following values may be used for the
+\fIflags\fR argument to procedures such as \fBTcl_EvalObjEx\fR:
+.TP 23
+\fBTCL_EVAL_DIRECT\fR
+.
+This flag is only used by \fBTcl_EvalObjEx\fR; it is ignored by
+other procedures.  If this flag bit is set, the script is not
+compiled to bytecodes; instead it is executed directly
+as is done by \fBTcl_EvalEx\fR.  The
+\fBTCL_EVAL_DIRECT\fR flag is useful in situations where the
+contents of a value are going to change immediately, so the
+bytecodes will not be reused in a future execution.  In this case,
+it is faster to execute the script directly.
+.TP 23
+\fBTCL_EVAL_GLOBAL\fR
+.
+If this flag is set, the script is processed at global level.  This
+means that it is evaluated in the global namespace and its variable
+context consists of global variables only (it ignores any Tcl
+procedures that are active).
+
+.SH "MISCELLANEOUS DETAILS"
+.PP
+During the processing of a Tcl command it is legal to make nested
+calls to evaluate other commands (this is how procedures and
+some control structures are implemented).
+If a code other than \fBTCL_OK\fR is returned
+from a nested \fBTcl_EvalObjEx\fR invocation,
+then the caller should normally return immediately,
+passing that same return code back to its caller,
+and so on until the top-level application is reached.
+A few commands, like \fBfor\fR, will check for certain
+return codes, like \fBTCL_BREAK\fR and \fBTCL_CONTINUE\fR, and process them
+specially without returning.
+.PP
+\fBTcl_EvalObjEx\fR keeps track of how many nested \fBTcl_EvalObjEx\fR
+invocations are in progress for \fIinterp\fR.
+If a code of \fBTCL_RETURN\fR, \fBTCL_BREAK\fR, or \fBTCL_CONTINUE\fR is
+about to be returned from the topmost \fBTcl_EvalObjEx\fR
+invocation for \fIinterp\fR,
+it converts the return code to \fBTCL_ERROR\fR
+and sets \fIinterp\fR's result to an error message indicating that
+the \fBreturn\fR, \fBbreak\fR, or \fBcontinue\fR command was
+invoked in an inappropriate place.
+This means that top-level applications should never see a return code
+from \fBTcl_EvalObjEx\fR other then \fBTCL_OK\fR or \fBTCL_ERROR\fR.

+.BE
+
+.SH DESCRIPTION
+.PP
+The procedures described here provide a graceful mechanism to end the
+execution of a \fBTcl\fR application. Exit handlers are invoked to cleanup the
+application's state before ending the execution of \fBTcl\fR code.
+.PP
+Invoke \fBTcl_Exit\fR to end a \fBTcl\fR application and to exit from this
+process. This procedure is invoked by the \fBexit\fR command, and can be
+invoked anyplace else to terminate the application.
+No-one should ever invoke the \fBexit\fR system procedure directly;  always
+invoke \fBTcl_Exit\fR instead, so that it can invoke exit handlers.
+Note that if other code invokes \fBexit\fR system procedure directly, or
+otherwise causes the application to terminate without calling
+\fBTcl_Exit\fR, the exit handlers will not be run.
+\fBTcl_Exit\fR internally invokes the \fBexit\fR system call, thus it never
+returns control to its caller.
+If an application exit handler has been installed (see
+\fBTcl_SetExitProc\fR), that handler is invoked with an argument
+consisting of the exit status (cast to ClientData); the application
+exit handler should not return control to Tcl.
+.PP
+\fBTcl_Finalize\fR is similar to \fBTcl_Exit\fR except that it does not
+exit from the current process.
+It is useful for cleaning up when a process is finished using \fBTcl\fR but
+wishes to continue executing, and when \fBTcl\fR is used in a dynamically
+loaded extension that is about to be unloaded.
+Your code should always invoke \fBTcl_Finalize\fR when \fBTcl\fR is being
+unloaded, to ensure proper cleanup. \fBTcl_Finalize\fR can be safely called
+more than once.
+.PP
+\fBTcl_ExitThread\fR is used to terminate the current thread and invoke
+per-thread exit handlers.  This finalization is done by
+\fBTcl_FinalizeThread\fR, which you can call if you just want to clean
+up per-thread state and invoke the thread exit handlers.
+\fBTcl_Finalize\fR calls \fBTcl_FinalizeThread\fR for the current
+thread automatically.
+.PP
+\fBTcl_CreateExitHandler\fR arranges for \fIproc\fR to be invoked
+by \fBTcl_Finalize\fR and \fBTcl_Exit\fR.
+\fBTcl_CreateThreadExitHandler\fR arranges for \fIproc\fR to be invoked
+by \fBTcl_FinalizeThread\fR and \fBTcl_ExitThread\fR.
+This provides a hook for cleanup operations such as flushing buffers
+and freeing global memory.
+\fIProc\fR should match the type \fBTcl_ExitProc\fR:
+.PP
+.CS
+typedef void \fBTcl_ExitProc\fR(
+        ClientData \fIclientData\fR);
+.CE
+.PP
+The \fIclientData\fR parameter to \fIproc\fR is a
+copy of the \fIclientData\fR argument given to
+\fBTcl_CreateExitHandler\fR or \fBTcl_CreateThreadExitHandler\fR when
+the callback
+was created.  Typically, \fIclientData\fR points to a data
+structure containing application-specific information about
+what to do in \fIproc\fR.
+.PP
+\fBTcl_DeleteExitHandler\fR and \fBTcl_DeleteThreadExitHandler\fR may be
+called to delete a
+previously-created exit handler.  It removes the handler
+indicated by \fIproc\fR and \fIclientData\fR so that no call
+to \fIproc\fR will be made.  If no such handler exists then
+\fBTcl_DeleteExitHandler\fR or \fBTcl_DeleteThreadExitHandler\fR does nothing.
+.PP
+\fBTcl_Finalize\fR and \fBTcl_Exit\fR execute all registered exit handlers,
+in reverse order from the order in which they were registered.
+This matches the natural order in which extensions are loaded and unloaded;
+if extension \fBA\fR loads extension \fBB\fR, it usually
+unloads \fBB\fR before it itself is unloaded.
+If extension \fBA\fR registers its exit handlers before loading extension
+\fBB\fR, this ensures that any exit handlers for \fBB\fR will be executed
+before the exit handlers for \fBA\fR.
+.PP
+\fBTcl_Finalize\fR and \fBTcl_Exit\fR call \fBTcl_FinalizeThread\fR 
+and the thread exit handlers \fIafter\fR
+the process-wide exit handlers.  This is because thread finalization shuts
+down the I/O channel system, so any attempt at I/O by the global exit
+handlers will vanish into the bitbucket.
+.PP
+\fBTcl_SetExitProc\fR installs an application exit handler, returning
+the previously-installed application exit handler or NULL if no
+application handler was installed.  If an application exit handler is
+installed, that exit handler takes over complete responsibility for
+finalization of Tcl's subsystems via \fBTcl_Finalize\fR at an
+appropriate time.  The argument passed to \fIproc\fR when it is
+invoked will be the exit status code (as passed to \fBTcl_Exit\fR)
+cast to a ClientData value.

+.PP
+These four procedures all evaluate the expression
+given by the \fIexpr\fR argument
+and return the result in one of four different forms.
+The expression can have any of the forms accepted by the \fBexpr\fR command.
+Note that these procedures have been largely replaced by the
+value-based procedures \fBTcl_ExprLongObj\fR, \fBTcl_ExprDoubleObj\fR,
+\fBTcl_ExprBooleanObj\fR, and \fBTcl_ExprObj\fR.
+Those value-based procedures evaluate an expression held in a Tcl value
+instead of a string.
+The value argument can retain an internal representation
+that is more efficient to execute.
+.PP
+The \fIinterp\fR argument refers to an interpreter used to
+evaluate the expression (e.g. for variables and nested Tcl
+commands) and to return error information.
+.PP
+For all of these procedures the return value is a standard
+Tcl result: \fBTCL_OK\fR means the expression was successfully
+evaluated, and \fBTCL_ERROR\fR means that an error occurred while
+evaluating the expression.
+If \fBTCL_ERROR\fR is returned then
+the interpreter's result will hold a message describing the error.
+If an error occurs while executing a Tcl command embedded in
+the expression then that error will be returned.
+.PP
+If the expression is successfully evaluated, then its value is
+returned in one of four forms, depending on which procedure
+is invoked.
+\fBTcl_ExprLong\fR stores an integer value at \fI*longPtr\fR.
+If the expression's actual value is a floating-point number,
+then it is truncated to an integer.
+If the expression's actual value is a non-numeric string then
+an error is returned.
+.PP
+\fBTcl_ExprDouble\fR stores a floating-point value at \fI*doublePtr\fR.
+If the expression's actual value is an integer, it is converted to
+floating-point.
+If the expression's actual value is a non-numeric string then
+an error is returned.
+.PP
+\fBTcl_ExprBoolean\fR stores a 0/1 integer value at \fI*booleanPtr\fR.
+If the expression's actual value is an integer or floating-point
+number, then they store 0 at \fI*booleanPtr\fR if
+the value was zero and 1 otherwise.
+If the expression's actual value is a non-numeric string then
+it must be one of the values accepted by \fBTcl_GetBoolean\fR
+such as
+.QW yes
+or
+.QW no ,

+\fBTcl_ExprString\fR returns the value of the expression as a

+.SH DESCRIPTION
+.PP
+There are several reasons for calling the \fBTcl_FS\fR API functions
+(e.g.\ \fBTcl_FSAccess\fR and \fBTcl_FSStat\fR)
+rather than calling system level functions like \fBaccess\fR and
+\fBstat\fR directly. First, they will work cross-platform, so an
+extension which calls them should work unmodified on Unix and
+Windows. Second, the Windows implementation of some of these functions
+fixes some bugs in the system level calls. Third, these function calls
+deal with any
+.QW "Utf to platform-native"
+path conversions which may be
+required (and may cache the results of such conversions for greater
+efficiency on subsequent calls). Fourth, and perhaps most importantly,
+all of these functions are
+.QW "virtual filesystem aware" .
+Any virtual filesystem (VFS for short) which has been registered (through
+\fBTcl_FSRegister\fR) may reroute file access to alternative
+media or access methods. This means that all of these functions (and
+therefore the corresponding \fBfile\fR, \fBglob\fR, \fBpwd\fR, \fBcd\fR,
+\fBopen\fR, etc.\ Tcl commands) may be operate on
+.QW files
+which are not
+native files in the native filesystem. This also means that any Tcl
+extension which accesses the filesystem (FS for short) through this API is
+automatically
+.QW "virtual filesystem aware" .
+Of course, if an extension
+accesses the native filesystem directly (through platform-specific
+APIs, for example), then Tcl cannot intercept such calls.
+.PP
+If appropriate VFSes have been registered, the
+.QW files
+may, to give two
+examples, be remote (e.g.\ situated on a remote ftp server) or archived
+(e.g.\ lying inside a .zip archive). Such registered filesystems provide
+a lookup table of functions to implement all or some of the functionality
+listed here. Finally, the \fBTcl_FSStat\fR and \fBTcl_FSLstat\fR calls
+abstract away from what the
+.QW "struct stat"
+buffer is actually
+declared to be, allowing the same code to be used both on systems with
+and systems without support for files larger than 2GB in size.
+.PP
+The \fBTcl_FS\fR API is \fBTcl_Obj\fR-ified and may cache internal
+representations and other path-related strings (e.g.\ the current working
+directory). One side-effect of this is that one must not pass in values
+with a reference count of zero to any of these functions. If such calls were
+handled, they might result
+in memory leaks (under some circumstances, the filesystem code may wish
+to retain a reference to the passed in value, and so one must not assume
+that after any of these calls return, the value still has a reference count of
+zero - it may have been incremented) or in a direct segmentation fault
+(or other memory access error)
+due to the value being freed part way through the complex value
+manipulation required to ensure that the path is fully normalized and
+absolute for filesystem determination. The practical lesson to learn
+from this is that
+.PP
+.CS
+Tcl_Obj *path = Tcl_NewStringObj(...);
+Tcl_FS\fIWhatever\fR(path);
+Tcl_DecrRefCount(path);
+.CE
+.PP
+is wrong, and may cause memory errors. The \fIpath\fR must have its
+reference count incremented before passing it in, or
+decrementing it. For this reason, values with a reference count of zero are
+considered not to be valid filesystem paths and calling any Tcl_FS API
+function with such a value will result in no action being taken.
+.SS "FS API FUNCTIONS"
+\fBTcl_FSCopyFile\fR attempts to copy the file given by \fIsrcPathPtr\fR to the
+path name given by \fIdestPathPtr\fR. If the two paths given lie in the same
+filesystem (according to \fBTcl_FSGetFileSystemForPath\fR) then that
+filesystem's
+.QW "copy file"
+function is called (if it is non-NULL).
+Otherwise the function returns -1 and sets the \fBerrno\fR global C
+variable to the
+.QW EXDEV
+POSIX error code (which signifies a
+.QW "cross-domain link" ).
+.PP
+\fBTcl_FSCopyDirectory\fR attempts to copy the directory given by \fIsrcPathPtr\fR to the
+path name given by \fIdestPathPtr\fR. If the two paths given lie in the same
+filesystem (according to \fBTcl_FSGetFileSystemForPath\fR) then that
+filesystem's
+.QW "copy file"
+function is called (if it is non-NULL).
+Otherwise the function returns -1 and sets the \fBerrno\fR global C
+variable to the
+.QW EXDEV
+POSIX error code (which signifies a
+.QW "cross-domain link" ).
+.PP
+\fBTcl_FSCreateDirectory\fR attempts to create the directory given by
+\fIpathPtr\fR by calling the owning filesystem's
+.QW "create directory"
+function.
+.PP
+\fBTcl_FSDeleteFile\fR attempts to delete the file given by
+\fIpathPtr\fR by calling the owning filesystem's
+.QW "delete file"
+function.
+.PP
+\fBTcl_FSRemoveDirectory\fR attempts to remove the directory given by
+\fIpathPtr\fR by calling the owning filesystem's
+.QW "remove directory"
+function.
+.PP
+\fBTcl_FSRenameFile\fR attempts to rename the file or directory given by
+\fIsrcPathPtr\fR to the path name given by \fIdestPathPtr\fR. If the two paths
+given lie in the same filesystem (according to
+\fBTcl_FSGetFileSystemForPath\fR) then that filesystem's
+.QW "rename file"
+function is called (if it is non-NULL). Otherwise the function returns -1
+and sets the \fBerrno\fR global C variable to the
+.QW EXDEV
+POSIX error code (which signifies a
+.QW "cross-domain link" ).
+.PP
+\fBTcl_FSListVolumes\fR calls each filesystem which has a non-NULL
+.QW "list volumes"
+function and asks them to return their list of root volumes. It
+accumulates the return values in a list which is returned to the
+caller (with a reference count of 0).
+.PP
+\fBTcl_FSEvalFileEx\fR reads the file given by \fIpathPtr\fR using
+the encoding identified by \fIencodingName\fR and evaluates
+its contents as a Tcl script. It returns the same information as
+\fBTcl_EvalObjEx\fR.
+If \fIencodingName\fR is NULL, the system encoding is used for
+reading the file contents.
+If the file could not be read then a Tcl error is returned to describe
+why the file could not be read.
+The eofchar for files is
+.QW \e32
+(^Z) for all platforms.
+If you require a
+.QW ^Z
+in code for string comparison, you can use
+.QW \e032
+or
+.QW \eu001a ,
+which will be safely substituted by the Tcl interpreter into
+.QW ^Z .
+\fBTcl_FSEvalFile\fR is a simpler version of
+\fBTcl_FSEvalFileEx\fR that always uses the system encoding
+when reading the file.
+.PP
+\fBTcl_FSLoadFile\fR dynamically loads a binary code file into memory and
+returns the addresses of two procedures within that file, if they are
+defined. The appropriate function for the filesystem to which \fIpathPtr\fR
+belongs will be called. If that filesystem does not implement this
+function (most virtual filesystems will not, because of OS limitations
+in dynamically loading binary code), Tcl will attempt to copy the file
+to a temporary directory and load that temporary file.
+.VS 8.6
+\fBTcl_FSUnloadFile\fR reverses the operation, asking for the library
+indicated by the \fIloadHandle\fR to be removed from the process. Note that,
+unlike with the \fBunload\fR command, this does not give the library any
+opportunity to clean up.
+.VE 8.6
+.PP
+Both the above functions return a standard Tcl completion code. If an error
+occurs, an error message is left in the \fIinterp\fR's result.
+.PP
+.VS 8.6
+The token provided via the variable indicated by \fIloadHandlePtr\fR may be
+used with \fBTcl_FindSymbol\fR.
+.VE 8.6
+.PP
+\fBTcl_FSMatchInDirectory\fR is used by the globbing code to search a
+directory for all files which match a given pattern. The appropriate
+function for the filesystem to which \fIpathPtr\fR belongs will be called.
+.PP
+The return value is a standard Tcl result indicating whether an error
+occurred in globbing. Error messages are placed in interp (unless 
+interp is NULL, which is allowed), but good results are placed in the 
+resultPtr given.
+.PP
+Note that the \fBglob\fR code implements recursive patterns internally, so
+this function will only ever be passed simple patterns, which can be
+matched using the logic of \fBstring match\fR. To handle recursion, Tcl
+will call this function frequently asking only for directories to be
+returned. A special case of being called with a NULL pattern indicates
+that the path needs to be checked only for the correct type.
+.PP
+\fBTcl_FSLink\fR replaces the library version of \fBreadlink\fR, and
+extends it to support the creation of links. The appropriate function
+for the filesystem to which \fIlinkNamePtr\fR belongs will be called.
+.PP
+If the \fItoPtr\fR is NULL, a
+.QW "read link"
+action is performed. The result
+is a Tcl_Obj specifying the contents of the symbolic link given by
+\fIlinkNamePtr\fR, or NULL if the link could not be read. The result is owned
+by the caller, which should call \fBTcl_DecrRefCount\fR when the result is no
+longer needed. If the \fItoPtr\fR is not NULL, Tcl should create a link
+of one of the types passed in in the \fIlinkAction\fR flag. This flag is
+an ORed combination of \fBTCL_CREATE_SYMBOLIC_LINK\fR and \fBTCL_CREATE_HARD_LINK\fR.
+Where a choice exists (i.e.\ more than one flag is passed in), the Tcl
+convention is to prefer symbolic links. When a link is successfully
+created, the return value should be \fItoPtr\fR (which is therefore
+already owned by the caller). If unsuccessful, NULL is returned.
+.PP
+\fBTcl_FSLstat\fR fills the \fITcl_StatBuf\fR structure \fIstatPtr\fR with
+information about the specified file. You do not need any access rights to the
+file to get this information but you need search rights to all
+directories named in the path leading to the file. The \fITcl_StatBuf\fR
+structure includes info regarding device, inode (always 0 on Windows),
+privilege mode, nlink (always 1 on Windows), user id (always 0 on
+Windows), group id (always 0 on Windows), rdev (same as device on
+Windows), size, last access time, last modification time, and
+last metadata change time.
+See \fBPORTABLE STAT RESULT API\fR for a description of how to write
+portable code to allocate and access the \fITcl_StatBuf\fR structure.
+.PP
+If \fIpath\fR exists, \fBTcl_FSLstat\fR returns 0 and the stat structure
+is filled with data. Otherwise, -1 is returned, and no stat info is
+given.
+.PP
+\fBTcl_FSUtime\fR replaces the library version of utime.
+.PP
+This returns 0 on success and -1 on error (as per the \fButime\fR
+documentation). If successful, the function
+will update the
+.QW atime
+and
+.QW mtime
+values of the file given.
+.PP
+\fBTcl_FSFileAttrsGet\fR implements read access for the hookable \fBfile
+attributes\fR subcommand. The appropriate function for the filesystem to
+which \fIpathPtr\fR belongs will be called.
+.PP
+If the result is \fBTCL_OK\fR, then a value was placed in
+\fIobjPtrRef\fR, which
+will only be temporarily valid (unless \fBTcl_IncrRefCount\fR is called).
+.PP
+\fBTcl_FSFileAttrsSet\fR implements write access for the hookable \fBfile
+attributes\fR subcommand. The appropriate function for the filesystem to
+which \fIpathPtr\fR belongs will be called.
+.PP
+\fBTcl_FSFileAttrStrings\fR implements part of the hookable \fBfile
+attributes\fR subcommand. The appropriate function for the filesystem
+to which \fIpathPtr\fR belongs will be called.
+.PP
+The called procedure may either return an array of strings, or may
+instead return NULL and place a Tcl list into the given \fIobjPtrRef\fR. Tcl
+will take that list and first increment its reference count before using it.
+On completion of that use, Tcl will decrement its reference count. Hence if
+the list should be disposed of by Tcl when done, it should have a
+reference count of zero, and if the list should not be disposed of, the
+filesystem should ensure it retains a reference count to the value.
+.PP
+\fBTcl_FSAccess\fR checks whether the process would be allowed to read,
+write or test for existence of the file (or other filesystem object)
+whose name is \fIpathname\fR. If \fIpathname\fR is a symbolic link on Unix,
+then permissions of the file referred by this symbolic link are
+tested.
+.PP
+On success (all requested permissions granted), zero is returned. On
+error (at least one bit in mode asked for a permission that is denied,
+or some other error occurred), -1 is returned.
+.PP
+\fBTcl_FSStat\fR fills the \fITcl_StatBuf\fR structure \fIstatPtr\fR with
+information about the specified file. You do not need any access rights to the
+file to get this information but you need search rights to all
+directories named in the path leading to the file. The \fITcl_StatBuf\fR
+structure includes info regarding device, inode (always 0 on Windows),
+privilege mode, nlink (always 1 on Windows), user id (always 0 on
+Windows), group id (always 0 on Windows), rdev (same as device on
+Windows), size, last access time, last modification time, and
+last metadata change time.
+See \fBPORTABLE STAT RESULT API\fR for a description of how to write
+portable code to allocate and access the \fITcl_StatBuf\fR structure.
+.PP
+If \fIpath\fR exists, \fBTcl_FSStat\fR returns 0 and the stat structure
+is filled with data. Otherwise, -1 is returned, and no stat info is
+given.
+.PP
+\fBTcl_FSOpenFileChannel\fR opens a file specified by \fIpathPtr\fR and
+returns a channel handle that can be used to perform input and output on
+the file. This API is modeled after the \fBfopen\fR procedure of
+the Unix standard I/O library.
+The syntax and meaning of all arguments is similar to those
+given in the Tcl \fBopen\fR command when opening a file.
+If an error occurs while opening the channel, \fBTcl_FSOpenFileChannel\fR
+returns NULL and records a POSIX error code that can be
+retrieved with \fBTcl_GetErrno\fR.
+In addition, if \fIinterp\fR is non-NULL, \fBTcl_FSOpenFileChannel\fR
+leaves an error message in \fIinterp\fR's result after any error.
+.PP
+The newly created channel is not registered in the supplied interpreter; to
+register it, use \fBTcl_RegisterChannel\fR.
+If one of the standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR was
+previously closed, the act of creating the new channel also assigns it as a
+replacement for the standard channel.
+.PP
+\fBTcl_FSGetCwd\fR replaces the library version of \fBgetcwd\fR.
+.PP
+It returns the Tcl library's current working directory. This may be
+different to the native platform's working directory, which happens when
+the current working directory is not in the native filesystem.
+.PP
+The result is a pointer to a Tcl_Obj specifying the current directory,
+or NULL if the current directory could not be determined. If NULL is
+returned, an error message is left in the \fIinterp\fR's result.
+.PP
+The result already has its reference count incremented for the caller. When
+it is no longer needed, that reference count should be decremented. This is
+needed for thread-safety purposes, to allow multiple threads to access
+this and related functions, while ensuring the results are always
+valid.
+.PP
+\fBTcl_FSChdir\fR replaces the library version of \fBchdir\fR. The path is
+normalized and then passed to the filesystem which claims it. If that
+filesystem does not implement this function, Tcl will fallback to a
+combination of \fBstat\fR and \fBaccess\fR to check whether the directory
+exists and has appropriate permissions.
+.PP
+For results, see \fBchdir\fR documentation. If successful, we keep a
+record of the successful path in \fIcwdPathPtr\fR for subsequent calls to
+\fBTcl_FSGetCwd\fR.
+.PP
+\fBTcl_FSPathSeparator\fR returns the separator character to be used for
+most specific element of the path specified by \fIpathPtr\fR (i.e.\ the last
+part of the path).
+.PP
+The separator is returned as a Tcl_Obj containing a string of length
+1. If the path is invalid, NULL is returned.
+.PP
+\fBTcl_FSJoinPath\fR takes the given Tcl_Obj, which must be a valid
+list (which is allowed to have a reference count of zero), and returns the path
+value given by considering the first \fIelements\fR elements as valid path
+segments (each path segment may be a complete path, a partial path or
+just a single possible directory or file name). If any path segment is
+actually an absolute path, then all prior path segments are discarded.
+If \fIelements\fR is less than 0, we use the entire list.
+.PP
+It is possible that the returned value is actually an element
+of the given list, so the caller should be careful to increment the
+reference count of the result before freeing the list.
+.PP
+The returned value, typically with a reference count of zero (but it
+could be shared
+under some conditions), contains the joined path. The caller must
+add a reference count to the value before using it. In particular, the
+returned value could be an element of the given list, so freeing the
+list might free the value prematurely if no reference count has been taken.
+If the number of elements is zero, then the returned value will be
+an empty-string Tcl_Obj.
+.PP
+\fBTcl_FSSplitPath\fR takes the given Tcl_Obj, which should be a valid path,
+and returns a Tcl list value containing each segment of that path as
+an element.
+It returns a list value with a reference count of zero. If the
+passed in \fIlenPtr\fR is non-NULL, the variable it points to will be
+updated to contain the number of elements in the returned list.
+.PP
+\fBTcl_FSEqualPaths\fR tests whether the two paths given represent the same
+filesystem object.
+It returns 1 if the paths are equal, and 0 if they are different. If
+either path is NULL, 0 is always returned.
+.PP
+\fBTcl_FSGetNormalizedPath\fR this important function attempts to extract
+from the given Tcl_Obj a unique normalized path representation, whose
+string value can be used as a unique identifier for the file.
+.PP
+It returns the normalized path value, owned by Tcl, or NULL if the path
+was invalid or could otherwise not be successfully converted.
+Extraction of absolute, normalized paths is very efficient (because the
+filesystem operates on these representations internally), although the
+result when the filesystem contains numerous symbolic links may not be
+the most user-friendly version of a path. The return value is owned by
+Tcl and has a lifetime equivalent to that of the \fIpathPtr\fR passed in
+(unless that is a relative path, in which case the normalized path
+value may be freed any time the cwd changes) - the caller can of
+course increment the reference count if it wishes to maintain a copy for longer.
+.PP
+\fBTcl_FSJoinToPath\fR takes the given value, which should usually be a
+valid path or NULL, and joins onto it the array of paths segments
+given.
+.PP
+Returns a value, typically with reference count of zero (but it could be shared
+under some conditions), containing the joined path. The caller must
+add a reference count to the value before using it. If any of the values
+passed into this function (\fIpathPtr\fR or \fIpath\fR elements) have
+a reference count
+of zero, they will be freed when this function returns.
+.PP
+\fBTcl_FSConvertToPathType\fR tries to convert the given Tcl_Obj to a valid
+Tcl path type, taking account of the fact that the cwd may have changed
+even if this value is already supposedly of the correct type.
+The filename may begin with
+.QW ~
+(to indicate current user's home directory) or
+.QW ~<user>
+(to indicate any user's home directory).
+.PP
+If the conversion succeeds (i.e.\ the value is a valid path in one of
+the current filesystems), then \fBTCL_OK\fR is returned. Otherwise
+\fBTCL_ERROR\fR is returned, and an error message may
+be left in the interpreter.
+.PP
+\fBTcl_FSGetInternalRep\fR extracts the internal representation of a given
+path value, in the given filesystem. If the path value belongs to a
+different filesystem, we return NULL. If the internal representation is
+currently NULL, we attempt to generate it, by calling the filesystem's
+\fBTcl_FSCreateInternalRepProc\fR.
+.PP
+Returns NULL or a valid internal path representation. This internal
+representation is cached, so that repeated calls to this function will
+not require additional conversions.
+.PP
+\fBTcl_FSGetTranslatedPath\fR attempts to extract the translated path
+from the given Tcl_Obj.
+.PP
+If the translation succeeds (i.e.\ the value is a valid path), then it is
+returned. Otherwise NULL will be returned, and an error message may be
+left in the interpreter. A
+.QW translated
+path is one which contains no
+.QW ~
+or
+.QW ~user
+sequences (these have been expanded to their current
+representation in the filesystem). The value returned is owned by the
+caller, which must store it or call \fBTcl_DecrRefCount\fR to ensure memory is
+freed. This function is of little practical use, and
+\fBTcl_FSGetNormalizedPath\fR or \fBTcl_FSGetNativePath\fR are usually
+better functions to use for most purposes.
+.PP
+\fBTcl_FSGetTranslatedStringPath\fR does the same as
+\fBTcl_FSGetTranslatedPath\fR, but returns a character string or NULL.
+The string returned is dynamically allocated and owned by the caller,
+which must store it or call \fBckfree\fR to ensure it is freed. Again,
+\fBTcl_FSGetNormalizedPath\fR or \fBTcl_FSGetNativePath\fR are usually
+better functions to use for most purposes.
+.PP
+\fBTcl_FSNewNativePath\fR performs something like the reverse of the
+usual obj->path->nativerep conversions. If some code retrieves a path
+in native form (from, e.g.\ \fBreadlink\fR or a native dialog), and that path
+is to be used at the Tcl level, then calling this function is an
+efficient way of creating the appropriate path value type.
+.PP
+The resulting value is a pure
+.QW path
+value, which will only receive
+a UTF-8 string representation if that is required by some Tcl code.
+.PP
+\fBTcl_FSGetNativePath\fR is for use by the Win/Unix native
+filesystems, so that they can easily retrieve the native (char* or
+TCHAR*) representation of a path. This function is a convenience
+wrapper around \fBTcl_FSGetInternalRep\fR. It may be desirable in the
+future to have non-string-based native representations (for example,
+on MacOSX, a representation using a fileSpec of FSRef structure would
+probably be more efficient). On Windows a full Unicode representation
+would allow for paths of unlimited length. Currently the representation
+is simply a character string which may contain either the relative path
+or a complete, absolute normalized path in the native encoding (complex
+conditions dictate which of these will be provided, so neither can be
+relied upon, unless the path is known to be absolute). If you need a
+native path which must be absolute, then you should ask for the native
+version of a normalized path. If for some reason a non-absolute,
+non-normalized version of the path is needed, that must be constructed
+separately (e.g.\ using \fBTcl_FSGetTranslatedPath\fR).
+.PP
+The native representation is cached so that repeated calls to this
+function will not require additional conversions. The return value is
+owned by Tcl and has a lifetime equivalent to that of the \fIpathPtr\fR
+passed in (unless that is a relative path, in which case the native
+representation may be freed any time the cwd changes).
+.PP
+\fBTcl_FSFileSystemInfo\fR returns a list of two elements. The first
+element is the name of the filesystem (e.g.
+.QW native ,
+.QW vfs ,
+.QW zip ,
+or
+.QW prowrap ,
+perhaps), and the second is the particular type of the
+given path within that filesystem (which is filesystem dependent). The
+second element may be empty if the filesystem does not provide a
+further categorization of files.
+.PP
+A valid list value is returned, unless the path value is not
+recognized, when NULL will be returned.
+.PP
+\fBTcl_FSGetFileSystemForPath\fR returns a pointer to the
+\fBTcl_Filesystem\fR which accepts this path as valid.
+.PP
+If no filesystem will accept the path, NULL is returned.
+.PP
+\fBTcl_FSGetPathType\fR determines whether the given path is relative
+to the current directory, relative to the current volume, or
+absolute.
+.PP
+It returns one of \fBTCL_PATH_ABSOLUTE\fR, \fBTCL_PATH_RELATIVE\fR, or
+\fBTCL_PATH_VOLUME_RELATIVE\fR
+.SS "PORTABLE STAT RESULT API"
+.PP
+\fBTcl_AllocStatBuf\fR allocates a \fITcl_StatBuf\fR on the system heap (which
+may be deallocated by being passed to \fBckfree\fR). This allows extensions to
+invoke \fBTcl_FSStat\fR and \fBTcl_FSLstat\fR without being dependent on the
+size of the buffer. That in turn depends on the flags used to build Tcl.

+.PP
+A filesystem provides a \fBTcl_Filesystem\fR structure that contains
+pointers to functions that implement the various operations on a
+filesystem; these operations are invoked as needed by the generic
+layer, which generally occurs through the functions listed above.
+.PP
+The \fBTcl_Filesystem\fR structures are manipulated using the following
+methods.
+.PP
+\fBTcl_FSRegister\fR takes a pointer to a filesystem structure and an
+optional piece of data to associated with that filesystem. On calling
+this function, Tcl will attach the filesystem to the list of known
+filesystems, and it will become fully functional immediately. Tcl does
+not check if the same filesystem is registered multiple times (and in
+general that is not a good thing to do). \fBTCL_OK\fR will be returned.
+.PP
+\fBTcl_FSUnregister\fR removes the given filesystem structure from
+the list of known filesystems, if it is known, and returns \fBTCL_OK\fR. If
+the filesystem is not currently registered, \fBTCL_ERROR\fR is returned.
+.PP
+\fBTcl_FSData\fR will return the ClientData associated with the given
+filesystem, if that filesystem is registered. Otherwise it will
+return NULL.
+.PP
+\fBTcl_FSMountsChanged\fR is used to inform the Tcl's core that
+the set of mount points for the given (already registered) filesystem
+have changed, and that cached file representations may therefore no
+longer be correct.

+.PP
+Except for the first three fields in this structure which contain
+simple data elements, all entries contain addresses of functions called
+by the generic filesystem layer to perform the complete range of
+filesystem related actions.
+.PP
+The many functions in this structure are broken down into three
+categories: infrastructure functions (almost all of which must be
+implemented), operational functions (which must be implemented if a
+complete filesystem is provided), and efficiency functions (which need
+only be implemented if they can be done so efficiently, or if they have
+side-effects which are required by the filesystem; Tcl has less
+efficient emulations it can fall back on). It is important to note
+that, in the current version of Tcl, most of these fallbacks are only
+used to handle commands initiated in Tcl, not in C. What this means is,
+that if a \fBfile rename\fR command is issued in Tcl, and the relevant
+filesystem(s) do not implement their \fITcl_FSRenameFileProc\fR, Tcl's
+core will instead fallback on a combination of other filesystem
+functions (it will use \fITcl_FSCopyFileProc\fR followed by
+\fITcl_FSDeleteFileProc\fR, and if \fITcl_FSCopyFileProc\fR is not
+implemented there is a further fallback). However, if a
+\fITcl_FSRenameFileProc\fR command is issued at the C level, no such
+fallbacks occur. This is true except for the last four entries in the
+filesystem table (\fBlstat\fR, \fBload\fR, \fBgetcwd\fR and \fBchdir\fR)
+for which fallbacks do in fact occur at the C level.
+.PP
+Any functions which take path names in Tcl_Obj form take
+those names in UTF\-8 form. The filesystem infrastructure API is
+designed to support efficient, cached conversion of these UTF\-8 paths
+to other native representations.

+return an internal (filesystem specific) representation of the path,
+which will be cached inside the path value, and may be retrieved

+.QW normalized
+string representation. Depending on the filesystem,

+refers to that path (e.g.\ a relative path, a path with different
+character case if the filesystem is case insensitive, a path contain a
+reference to a home directory such as
+.QW ~ ,
+a path containing symbolic
+links, etc). If the very last component in the path is a symbolic
+link, it should not be converted into the value it points to (but
+its case or other aspects should be made unique). All other path
+components should be converted from symbolic links. This one
+exception is required to agree with Tcl's semantics with \fBfile
+delete\fR, \fBfile rename\fR, \fBfile copy\fR operating on symbolic links.

+Function to process a \fBTcl_FSOpenFileChannel\fR call. Must be

+specification of a single file or directory which should be checked for
+existence and correct type. Otherwise, \fIpathPtr\fR is a directory, the

+which have the correct type. In either case, \fIpathPtr\fR can be
+assumed to be both non-NULL and non-empty. It is not currently
+documented whether \fIpathPtr\fR will have a file separator at its end of
+not, so code should be flexible to both possibilities.

+The return value is a standard Tcl result indicating whether an error
+occurred in the matching process. Error messages are placed in

+to \fIresultPtr\fR should include any path prefix given in \fIpathPtr\fR
+(this usually means they will be absolute path specifications).
+Note that if no matches are found, that simply leads to an empty
+result; errors are only signaled for actual file or filesystem
+problems which may occur during the matching process.
+.PP
+The \fBTcl_GlobTypeData\fR structure passed in the \fItypes\fR 
+parameter contains the following fields:
+.PP
+.CS
+typedef struct Tcl_GlobTypeData {
+    /* Corresponds to bcdpfls as in 'find -t' */

+    /* Acceptable mac creator */
+    Tcl_Obj *\fImacCreator\fR;
+} \fBTcl_GlobTypeData\fR;
+.CE
+.PP
+There are two specific cases which it is important to handle correctly,
+both when \fItypes\fR is non-NULL. The two cases are when \fItypes->types
+& TCL_GLOB_TYPE_DIR\fR or \fItypes->types & TCL_GLOB_TYPE_MOUNT\fR are
+true (and in particular when the other flags are false). In the first of
+these cases, the function must list the contained directories. Tcl uses
+this to implement recursive globbing, so it is critical that filesystems
+implement directory matching correctly. In the second of these cases,
+with \fBTCL_GLOB_TYPE_MOUNT\fR, the filesystem must list the mount points
+which lie within the given \fIpathPtr\fR (and in this case, \fIpathPtr\fR
+need not lie within the same filesystem - different to all other cases in
+which this function is called). Support for this is critical if Tcl is
+to have seamless transitions between from one filesystem to another.
+.SS UTIMEPROC
+.PP
+Function to process a \fBTcl_FSUtime\fR call. Required to allow setting
+(not reading) of times with \fBfile mtime\fR, \fBfile atime\fR and the
+open-r/open-w/fcopy implementation of \fBfile copy\fR.

+.CE
+.PP
+The access and modification times of the file specified by \fIpathPtr\fR
+should be changed to the values given in the \fItval\fR structure.
+.PP
+The return value should be 0 on success and -1 on an error, as
+with the system \fButime\fR.
+.SS LINKPROC
+.PP
+Function to process a \fBTcl_FSLink\fR call. Should be implemented
+only if the filesystem supports links, and may otherwise be NULL.
+.PP
+.CS
+typedef Tcl_Obj *\fBTcl_FSLinkProc\fR(
+        Tcl_Obj *\fIlinkNamePtr\fR,
+        Tcl_Obj *\fItoPtr\fR,
+        int \fIlinkAction\fR);
+.CE
+.PP
+If \fItoPtr\fR is NULL, the function is being asked to read the
+contents of a link. The result is a Tcl_Obj specifying the contents of
+the link given by \fIlinkNamePtr\fR, or NULL if the link could
+not be read. The result is owned by the caller (and should therefore
+have its ref count incremented before being returned). Any callers
+should call \fBTcl_DecrRefCount\fR on this result when it is no longer needed.
+If \fItoPtr\fR is not NULL, the function should attempt to create a link.
+The result in this case should be \fItoPtr\fR if the link was successful
+and NULL otherwise. In this case the result is not owned by the caller
+(i.e.\ no reference count manipulations on either end are needed). See
+the documentation for \fBTcl_FSLink\fR for the correct interpretation
+of the \fIlinkAction\fR flags.
+.SS LISTVOLUMESPROC
+.PP
+Function to list any filesystem volumes added by this filesystem.
+Should be implemented only if the filesystem adds volumes at the head
+of the filesystem, so that they can be returned by \fBfile volumes\fR.
+.PP
+.CS
+typedef Tcl_Obj *\fBTcl_FSListVolumesProc\fR(void);
+.CE
+.PP
+The result should be a list of volumes added by this filesystem, or
+NULL (or an empty list) if no volumes are provided. The result value
+is considered to be owned by the filesystem (not by Tcl's core), but
+should be given a reference count for Tcl. Tcl will use the contents of the
+list and then decrement that reference count. This allows filesystems to
+choose whether they actually want to retain a
+.QW "master list"
+of volumes
+or not (if not, they generate the list on the fly and pass it to Tcl
+with a reference count of 1 and then forget about the list, if yes, then
+they simply increment the reference count of their master list and pass it
+to Tcl which will copy the contents and then decrement the count back
+to where it was).
+.PP
+Therefore, Tcl considers return values from this proc to be read-only.
+.SS FILEATTRSTRINGSPROC
+.PP
+Function to list all attribute strings which are valid for this
+filesystem. If not implemented the filesystem will not support
+the \fBfile attributes\fR command. This allows arbitrary additional
+information to be attached to files in the filesystem. If it is
+not implemented, there is no need to implement the \fBget\fR and \fBset\fR
+methods.
+.PP
+.CS
+typedef const char *const *\fBTcl_FSFileAttrStringsProc\fR(
+        Tcl_Obj *\fIpathPtr\fR,
+        Tcl_Obj **\fIobjPtrRef\fR);
+.CE
+.PP
+The called function may either return an array of strings, or may
+instead return NULL and place a Tcl list into the given \fIobjPtrRef\fR. Tcl
+will take that list and first increment its reference count before using it.
+On completion of that use, Tcl will decrement its reference count. Hence if
+the list should be disposed of by Tcl when done, it should have a
+reference count of zero, and if the list should not be disposed of, the
+filesystem should ensure it returns a value with a reference count
+of at least one.
+.SS FILEATTRSGETPROC
+.PP
+Function to process a \fBTcl_FSFileAttrsGet\fR call, used by \fBfile
+attributes\fR.
+.PP

+.CE
+.PP
+Returns a standard Tcl return code. The attribute value retrieved,
+which corresponds to the \fIindex\fR'th element in the list returned by
+the \fBTcl_FSFileAttrStringsProc\fR, is a Tcl_Obj placed in \fIobjPtrRef\fR (if
+\fBTCL_OK\fR was returned) and is likely to have a reference count of zero. Either
+way we must either store it somewhere (e.g.\ the Tcl result), or
+Incr/Decr its reference count to ensure it is properly freed.
+.SS FILEATTRSSETPROC
+.PP
+Function to process a \fBTcl_FSFileAttrsSet\fR call, used by \fBfile
+attributes\fR. If the filesystem is read-only, there is no need
+to implement this.

+The attribute value of the \fIindex\fR'th element in the list returned by

+.PP
+.CS
+typedef int \fBTcl_FSCreateDirectoryProc\fR(

+.CE
+.PP
+The return value is a standard Tcl result indicating whether an error
+occurred in the process. If successful, the directory specified by
+\fIpathPtr\fR should have been removed from the filesystem. If the
+\fIrecursive\fR flag is given, then a non-empty directory should be
+deleted without error. If this flag is not given, then and the
+directory is non-empty a POSIX
+.QW EEXIST
+error should be signaled. If an
+error does occur, the name of the file or directory which caused the
+error should be placed in \fIerrorPtr\fR.

+.PP
+.CS
+typedef int \fBTcl_FSDeleteFileProc\fR(

+.CE
+.PP
+The return value is a standard Tcl result indicating whether an error
+occurred in the process. If successful, the file specified by
+\fIpathPtr\fR should have been removed from the filesystem. Note that,

+(even if they are symbolic links to directories).
+.SH "FILESYSTEM EFFICIENCY"
+.PP
+These functions need not be implemented for a particular filesystem

+.SS LSTATPROC
+.PP
+Function to process a \fBTcl_FSLstat\fR call. If not implemented, Tcl

+.PP
+The behavior of this function is very similar to that of the
+\fBTcl_FSStatProc\fR defined above, except that if it is applied
+to a symbolic link, it returns information about the link, not
+about the target file.
+.SS COPYFILEPROC
+.PP
+Function to process a \fBTcl_FSCopyFile\fR call. If not implemented Tcl
+will fall back on \fBopen\fR-r, \fBopen\fR-w and \fBfcopy\fR as a

+.PP
+The return value is a standard Tcl result indicating whether an error
+occurred in the copying process. Note that, \fIdestPathPtr\fR is the
+name of the file which should become the copy of \fIsrcPathPtr\fR. It
+is never the name of a directory into which \fIsrcPathPtr\fR could be
+copied (i.e.\ the function is much simpler than the Tcl level \fBfile

+calling \fBTcl_SetErrno(EXDEV)\fR and returning a non-\fBTCL_OK\fR
+result will tell Tcl to use its standard fallback mechanisms.
+.SS RENAMEFILEPROC

+Function to process a \fBTcl_FSRenameFile\fR call. If not implemented,

+.PP
+The return value is a standard Tcl result indicating whether an error
+occurred in the copying process. If an error does occur, the name of
+the file or directory which caused the error should be placed in
+\fIerrorPtr\fR. Note that, \fIdestPathPtr\fR is the name of the
+directory-name which should become the mirror-image of
+\fIsrcPathPtr\fR. It is not the name of a directory into which
+\fIsrcPathPtr\fR should be copied (i.e.\ the function is much simpler

+.SS LOADFILEPROC
+.PP
+Function to process a \fBTcl_FSLoadFile\fR call. If not implemented, Tcl
+will fall back on a copy to native-temp followed by a \fBTcl_FSLoadFile\fR on
+that temporary copy. Therefore it need only be implemented if the
+filesystem can load code directly, or it can be implemented simply to
+return \fBTCL_ERROR\fR to disable load functionality in this filesystem
+entirely.

+        Tcl_FSUnloadFileProc *\fIunloadProcPtr\fR);
+.CE
+.PP
+Returns a standard Tcl completion code. If an error occurs, an error
+message is left in the \fIinterp\fR's result. The function dynamically loads a
+binary code file into memory. On a successful load, the \fIhandlePtr\fR
+should be filled with a token for the dynamically loaded file, and the
+\fIunloadProcPtr\fR should be filled in with the address of a procedure.
+The unload procedure will be called with the given \fBTcl_LoadHandle\fR as its
+only parameter when Tcl needs to unload the file. For example, for the
+native filesystem, the \fBTcl_LoadHandle\fR returned is currently a token
+which can be used in the private \fBTclpFindSymbol\fR to access functions
+in the new code. Each filesystem is free to define the
+\fBTcl_LoadHandle\fR as it requires. Finally, if the

+.BE
+
+.SH DESCRIPTION
+.PP
+The \fBTcl_FindExecutable\fR procedure computes the full path name of
+the executable file from which the application was invoked and saves
+it for Tcl's internal use.
+The executable's path name is needed for several purposes in
+Tcl.  For example, it is needed on some platforms in the
+implementation of the \fBload\fR command.
+It is also returned by the \fBinfo nameofexecutable\fR command.
+.PP
+On UNIX platforms this procedure is typically invoked as the very
+first thing in the application's main program;  it must be passed
+\fIargv[0]\fR as its argument.  It is important not to change the
+working directory before the invocation.
+\fBTcl_FindExecutable\fR uses \fIargv0\fR
+along with the \fBPATH\fR environment variable to find the
+application's executable, if possible.  If it fails to find
+the binary, then future calls to \fBinfo nameofexecutable\fR
+will return an empty string.
+.PP
+On Windows platforms this procedure is typically invoked as the very
+first thing in the application's main program as well; Its \fIargv[0]\fR
+argument is only used to indicate whether the executable has a stderr
+channel (any non-null value) or not (the value null). If \fBTcl_SetPanicProc\fR
+is never called and no debugger is running, this determines whether
+the panic message is sent to stderr or to a standard system dialog.
+.PP
+\fBTcl_GetNameOfExecutable\fR simply returns a pointer to the
+internal full path name of the executable file as computed by
+\fBTcl_FindExecutable\fR.  This procedure call is the C API
+equivalent to the \fBinfo nameofexecutable\fR command.  NULL
+is returned if the internal full path name has not been
+computed or unknown.

+.BE
+.SH DESCRIPTION
+.PP
+These procedures provide an efficient way for looking up keywords,
+switch names, option names, and similar things where the literal value of
+a Tcl value must be chosen from a predefined set.
+\fBTcl_GetIndexFromObj\fR compares \fIobjPtr\fR against each of
+the strings in \fItablePtr\fR to find a match.  A match occurs if
+\fIobjPtr\fR's string value is identical to one of the strings in
+\fItablePtr\fR, or if it is a non-empty unique abbreviation
+for exactly one of the strings in \fItablePtr\fR and the
+\fBTCL_EXACT\fR flag was not specified; in either case
+the index of the matching entry is stored at \fI*indexPtr\fR
+and \fBTCL_OK\fR is returned.
+.PP
+If there is no matching entry,
+\fBTCL_ERROR\fR is returned and an error message is left in \fIinterp\fR's
+result if \fIinterp\fR is not NULL.  \fIMsg\fR is included in the
+error message to indicate what was being looked up.  For example,
+if \fImsg\fR is \fBoption\fR the error message will have a form like
+.QW "\fBbad option \N'34'firt\N'34': must be first, second, or third\fR" .
+.PP
+If \fBTcl_GetIndexFromObj\fR completes successfully it modifies the
+internal representation of \fIobjPtr\fR to hold the address of
+the table and the index of the matching entry.  If \fBTcl_GetIndexFromObj\fR
+is invoked again with the same \fIobjPtr\fR and \fItablePtr\fR
+arguments (e.g. during a reinvocation of a Tcl command), it returns
+the matching index immediately without having to redo the lookup
+operation.  Note: \fBTcl_GetIndexFromObj\fR assumes that the entries
+in \fItablePtr\fR are static: they must not change between
+invocations.  If the value of \fIobjPtr\fR is the empty string,
+\fBTcl_GetIndexFromObj\fR will treat it as a non-matching value
+and return \fBTCL_ERROR\fR.
+.PP
+\fBTcl_GetIndexFromObjStruct\fR works just like
+\fBTcl_GetIndexFromObj\fR, except that instead of treating
+\fItablePtr\fR as an array of string pointers, it treats it as a
+pointer to the first string in a series of strings that have
+\fIoffset\fR bytes between them (i.e. that there is a pointer to the
+first array of characters at \fItablePtr\fR, a pointer to the second
+array of characters at \fItablePtr\fR+\fIoffset\fR bytes, etc.)
+This is particularly useful when processing things like
+\fBTk_ConfigurationSpec\fR, whose string keys are in the same place in
+each of several array elements.

+.SH DESCRIPTION
+.PP
+These procedures convert from strings to integers or double-precision
+floating-point values or booleans (represented as 0- or 1-valued
+integers).  Each of the procedures takes a \fIsrc\fR argument,
+converts it to an internal form of a particular type, and stores
+the converted value at the location indicated by the procedure's
+third argument.  If all goes well, each of the procedures returns
+\fBTCL_OK\fR.  If \fIsrc\fR does not have the proper syntax for the
+desired type then \fBTCL_ERROR\fR is returned, an error message is left
+in the interpreter's result, and nothing is stored at *\fIintPtr\fR
+or *\fIdoublePtr\fR or *\fIboolPtr\fR.
+.PP
+\fBTcl_GetInt\fR expects \fIsrc\fR to consist of a collection
+of integer digits, optionally signed and optionally preceded by
+white space.  If the first two characters of \fIsrc\fR
+after the optional white space and sign are
+.QW 0x
+then \fIsrc\fR is expected to be in hexadecimal form;  otherwise,
+if the first such character is
+.QW 0
+then \fIsrc\fR
+is expected to be in octal form;  otherwise, \fIsrc\fR is
+expected to be in decimal form.
+.PP
+\fBTcl_GetDouble\fR expects \fIsrc\fR to consist of a floating-point
+number, which is:  white space;  a sign; a sequence of digits;  a
+decimal point;  a sequence of digits;  the letter
+.QW e ;
+a signed decimal exponent;  and more white space.
+Any of the fields may be omitted, except that
+the digits either before or after the decimal point must be present
+and if the
+.QW e
+is present then it must be followed by the exponent number.
+.PP
+\fBTcl_GetBoolean\fR expects \fIsrc\fR to specify a boolean
+value.  If \fIsrc\fR is any of \fB0\fR, \fBfalse\fR,
+\fBno\fR, or \fBoff\fR, then \fBTcl_GetBoolean\fR stores a zero
+value at \fI*boolPtr\fR.
+If \fIsrc\fR is any of \fB1\fR, \fBtrue\fR, \fByes\fR, or \fBon\fR,

+Tcl_GetStdChannel, Tcl_SetStdChannel \- procedures for retrieving and replacing the standard channels
+.SH SYNOPSIS
+.nf
+\fB#include <tcl.h>\fR
+.sp
+Tcl_Channel
+\fBTcl_GetStdChannel\fR(\fItype\fR)
+.sp
+\fBTcl_SetStdChannel\fR(\fIchannel, type\fR)
+.sp
+.SH ARGUMENTS
+.AS Tcl_Channel channel
+.AP int type in
+The identifier for the standard channel to retrieve or modify.  Must be one of
+\fBTCL_STDIN\fR, \fBTCL_STDOUT\fR, or \fBTCL_STDERR\fR.
+.AP Tcl_Channel channel in
+The channel to use as the new value for the specified standard channel.
+.BE
+
+.SH DESCRIPTION
+.PP
+Tcl defines three special channels that are used by various I/O related
+commands if no other channels are specified.  The standard input channel
+has a channel name of \fBstdin\fR and is used by \fBread\fR and \fBgets\fR.
+The standard output channel is named \fBstdout\fR and is used by
+\fBputs\fR.  The standard error channel is named \fBstderr\fR and is used for 
+reporting errors.  In addition, the standard channels are inherited by any
+child processes created using \fBexec\fR or \fBopen\fR in the absence of any
+other redirections.
+.PP
+The standard channels are actually aliases for other normal channels.  The
+current channel associated with a standard channel can be retrieved by calling
+\fBTcl_GetStdChannel\fR with one of 
+\fBTCL_STDIN\fR, \fBTCL_STDOUT\fR, or \fBTCL_STDERR\fR as the \fItype\fR.  The
+return value will be a valid channel, or NULL.
+.PP
+A new channel can be set for the standard channel specified by \fItype\fR 
+by calling \fBTcl_SetStdChannel\fR with a new channel or NULL in the
+\fIchannel\fR argument.  If the specified channel is closed by a later call to
+\fBTcl_Close\fR, then the corresponding standard channel will automatically be
+set to NULL.
+.PP
+If a non-NULL value for \fIchannel\fR is passed to \fBTcl_SetStdChannel\fR,
+then that same value should be passed to \fBTcl_RegisterChannel\fR, like so:
+.PP
+.CS
+Tcl_RegisterChannel(NULL, channel);
+.CE
+.PP
+This is a workaround for a misfeature in \fBTcl_SetStdChannel\fR that it
+fails to do some reference counting housekeeping.  This misfeature cannot
+be corrected without contradicting the assumptions of some existing
+code that calls \fBTcl_SetStdChannel\fR.
+.PP
+If \fBTcl_GetStdChannel\fR is called before \fBTcl_SetStdChannel\fR, Tcl will
+construct a new channel to wrap the appropriate platform-specific standard 
+file handle.  If \fBTcl_SetStdChannel\fR is called before
+\fBTcl_GetStdChannel\fR, then the default channel will not be created.
+.PP
+If one of the standard channels is set to NULL, either by calling
+\fBTcl_SetStdChannel\fR with a NULL \fIchannel\fR argument, or by calling
+\fBTcl_Close\fR on the channel, then the next call to \fBTcl_CreateChannel\fR
+will automatically set the standard channel with the newly created channel.  If
+more than one standard channel is NULL, then the standard channels will be
+assigned starting with standard input, followed by standard output, with
+standard error being last.
+.PP
+See \fBTcl_StandardChannels\fR for a general treatise about standard
+channels and the behavior of the Tcl library with regard to them.

+.BE
+.SH DESCRIPTION
+.PP
+The \fBTcl_GetTime\fR function retrieves the current time as a
+\fITcl_Time\fR structure in memory the caller provides.  This
+structure has the following definition:
+.PP
+.CS
+typedef struct Tcl_Time {
+    long \fIsec\fR;
+    long \fIusec\fR;
+} \fBTcl_Time\fR;
+.CE
+.PP
+On return, the \fIsec\fR member of the structure is filled in with the
+number of seconds that have elapsed since the \fIepoch:\fR the epoch
+is the point in time of 00:00 UTC, 1 January 1970.  This number does
+\fInot\fR count leap seconds \- an interval of one day advances it by
+86400 seconds regardless of whether a leap second has been inserted.
+.PP
+The \fIusec\fR member of the structure is filled in with the number of
+microseconds that have elapsed since the start of the second
+designated by \fIsec\fR.  The Tcl library makes every effort to keep
+this number as precise as possible, subject to the limitations of the
+computer system.  On multiprocessor variants of Windows, this number
+may be limited to the 10- or 20-ms granularity of the system clock.
+(On single-processor Windows systems, the \fIusec\fR field is derived
+from a performance counter and is highly precise.)
+.SS "VIRTUALIZED TIME"
+.PP
+The \fBTcl_SetTimeProc\fR function registers two related handler functions
+with the core. The first handler function is a replacement for
+\fBTcl_GetTime\fR, or rather the OS access made by
+\fBTcl_GetTime\fR. The other handler function is used by the Tcl
+notifier to convert wait/block times from the virtual domain into real
+time.
+.PP
+The \fBTcl_QueryTimeProc\fR function returns the currently registered
+handler functions. If no external handlers were set then this will
+return the standard handlers accessing and processing the native time
+of the OS. The arguments to the function are allowed to be NULL; and
+any argument which is NULL is ignored and not set.
+.PP
+The signatures of the handler functions are as follows:
+.PP
+.CS
+typedef void \fBTcl_GetTimeProc\fR(
+        Tcl_Time *\fItimebuf\fR,
+        ClientData \fIclientData\fR);
+typedef void \fBTcl_ScaleTimeProc\fR(
+        Tcl_Time *\fItimebuf\fR,
+        ClientData \fIclientData\fR);
+.CE
+.PP
+The \fItimebuf\fR fields contain the time to manipulate, and the
+\fIclientData\fR fields contain a pointer supplied at the time the handler
+functions were registered.
+.PP
+Any handler pair specified has to return data which is consistent between
+them. In other words, setting one handler of the pair to something assuming a
+10-times slowdown, and the other handler of the pair to something assuming a
+two-times slowdown is wrong and not allowed.
+.PP
+The set handler functions are allowed to run the delivered time backwards,
+however this should be avoided. We have to allow it as the native time can run
+backwards as the user can fiddle with the system time one way or other. Note
+that the insertion of the hooks will not change the behavior of the Tcl core
+with regard to this situation, i.e. the existing behavior is retained.

+.BE
+.SH DESCRIPTION
+.PP
+A hash table consists of zero or more entries, each consisting of a
+key and a value.  Given the key for an entry, the hashing routines can
+very quickly locate the entry, and hence its value. There may be at
+most one entry in a hash table with a particular key, but many entries
+may have the same value.  Keys can take one of four forms: strings,
+one-word values, integer arrays, or custom keys defined by a
+Tcl_HashKeyType structure (See section \fBTHE TCL_HASHKEYTYPE STRUCTURE\fR
+below). All of the keys in a given table have the same
+form, which is specified when the table is initialized.
+.PP
+The value of a hash table entry can be anything that fits in the same
+space as a
+.QW "char *"
+pointer.  Values for hash table entries are
+managed entirely by clients, not by the hash module itself.  Typically
+each entry's value is a pointer to a data structure managed by client
+code.
+.PP
+Hash tables grow gracefully as the number of entries increases, so
+that there are always less than three entries per hash bucket, on
+average. This allows for fast lookups regardless of the number of
+entries in a table.
+.PP
+The core provides three functions for the initialization of hash
+tables, Tcl_InitHashTable, Tcl_InitObjHashTable and
+Tcl_InitCustomHashTable.
+.PP
+\fBTcl_InitHashTable\fR initializes a structure that describes a new
+hash table.  The space for the structure is provided by the caller,
+not by the hash module.  The value of \fIkeyType\fR indicates what
+kinds of keys will be used for all entries in the table. All of the
+key types described later are allowed, with the exception of
+\fBTCL_CUSTOM_TYPE_KEYS\fR and \fBTCL_CUSTOM_PTR_KEYS\fR.
+.PP
+\fBTcl_InitObjHashTable\fR is a wrapper around
+\fBTcl_InitCustomHashTable\fR and initializes a hash table whose keys
+are Tcl_Obj *.
+.PP
+\fBTcl_InitCustomHashTable\fR initializes a structure that describes a
+new hash table. The space for the structure is provided by the
+caller, not by the hash module.  The value of \fIkeyType\fR indicates
+what kinds of keys will be used for all entries in the table.
+\fIKeyType\fR must have one of the following values:
+.IP \fBTCL_STRING_KEYS\fR 25
+Keys are null-terminated strings.
+They are passed to hashing routines using the address of the
+first character of the string.
+.IP \fBTCL_ONE_WORD_KEYS\fR 25
+Keys are single-word values;  they are passed to hashing routines
+and stored in hash table entries as
+.QW "char *"
+values.
+The pointer value is the key;  it need not (and usually does not)
+actually point to a string.
+.IP \fBTCL_CUSTOM_TYPE_KEYS\fR 25
+Keys are of arbitrary type, and are stored in the entry. Hashing
+and comparison is determined by \fItypePtr\fR. The Tcl_HashKeyType 
+structure is described in the section 
+\fBTHE TCL_HASHKEYTYPE STRUCTURE\fR below.
+.IP \fBTCL_CUSTOM_PTR_KEYS\fR 25
+Keys are pointers to an arbitrary type, and are stored in the entry. Hashing
+and comparison is determined by \fItypePtr\fR. The Tcl_HashKeyType 
+structure is described in the section 
+\fBTHE TCL_HASHKEYTYPE STRUCTURE\fR below.
+.IP \fIother\fR 25
+If \fIkeyType\fR is not one of the above,
+then it must be an integer value greater than 1.
+In this case the keys will be arrays of
+.QW int
+values, where
+\fIkeyType\fR gives the number of ints in each key.
+This allows structures to be used as keys.
+All keys must have the same size.
+Array keys are passed into hashing functions using the address
+of the first int in the array.
+.PP
+\fBTcl_DeleteHashTable\fR deletes all of the entries in a hash
+table and frees up the memory associated with the table's
+bucket array and entries.
+It does not free the actual table structure (pointed to
+by \fItablePtr\fR), since that memory is assumed to be managed
+by the client.
+\fBTcl_DeleteHashTable\fR also does not free or otherwise
+manipulate the values of the hash table entries.
+If the entry values point to dynamically-allocated memory, then
+it is the client's responsibility to free these structures
+before deleting the table.
+.PP
+\fBTcl_CreateHashEntry\fR locates the entry corresponding to a
+particular key, creating a new entry in the table if there
+was not already one with the given key.
+If an entry already existed with the given key then \fI*newPtr\fR
+is set to zero.
+If a new entry was created, then \fI*newPtr\fR is set to a non-zero
+value and the value of the new entry will be set to zero.
+The return value from \fBTcl_CreateHashEntry\fR is a pointer to
+the entry, which may be used to retrieve and modify the entry's
+value or to delete the entry from the table.
+.PP
+\fBTcl_DeleteHashEntry\fR will remove an existing entry from a
+table.
+The memory associated with the entry itself will be freed, but
+the client is responsible for any cleanup associated with the
+entry's value, such as freeing a structure that it points to.
+.PP
+\fBTcl_FindHashEntry\fR is similar to \fBTcl_CreateHashEntry\fR
+except that it does not create a new entry if the key doesn't exist;
+instead, it returns NULL as result.
+.PP
+\fBTcl_GetHashValue\fR and \fBTcl_SetHashValue\fR are used to
+read and write an entry's value, respectively.
+Values are stored and retrieved as type
+.QW ClientData ,
+which is
+large enough to hold a pointer value.  On almost all machines this is
+large enough to hold an integer value too.
+.PP
+\fBTcl_GetHashKey\fR returns the key for a given hash table entry,
+either as a pointer to a string, a one-word
+.PQ "char *"
+key, or
+as a pointer to the first word of an array of integers, depending
+on the \fIkeyType\fR used to create a hash table.
+In all cases \fBTcl_GetHashKey\fR returns a result with type
+.QW "char *" .
+When the key is a string or array, the result of \fBTcl_GetHashKey\fR
+points to information in the table entry;  this information will
+remain valid until the entry is deleted or its table is deleted.
+.PP
+\fBTcl_FirstHashEntry\fR and \fBTcl_NextHashEntry\fR may be used
+to scan all of the entries in a hash table.
+A structure of type
+.QW Tcl_HashSearch ,
+provided by the client,
+is used to keep track of progress through the table.
+\fBTcl_FirstHashEntry\fR initializes the search record and
+returns the first entry in the table (or NULL if the table is
+empty).
+Each subsequent call to \fBTcl_NextHashEntry\fR returns the
+next entry in the table or
+NULL if the end of the table has been reached.
+A call to \fBTcl_FirstHashEntry\fR followed by calls to
+\fBTcl_NextHashEntry\fR will return each of the entries in
+the table exactly once, in an arbitrary order.
+It is inadvisable to modify the structure of the table, e.g.
+by creating or deleting entries, while the search is in progress,
+with the exception of deleting the entry returned by
+\fBTcl_FirstHashEntry\fR or \fBTcl_NextHashEntry\fR.
+.PP
+\fBTcl_HashStats\fR returns a dynamically-allocated string with
+overall information about a hash table, such as the number of
+entries it contains, the number of buckets in its hash array,
+and the utilization of the buckets.
+It is the caller's responsibility to free the result string
+by passing it to \fBckfree\fR.
+.PP
+The header file \fBtcl.h\fR defines the actual data structures
+used to implement hash tables.
+This is necessary so that clients can allocate Tcl_HashTable
+structures and so that macros can be used to read and write
+the values of entries.
+However, users of the hashing routines should never refer directly
+to any of the fields of any of the hash-related data structures;
+use the procedures and macros defined here.
+.SH "THE TCL_HASHKEYTYPE STRUCTURE"
+.PP
+Extension writers can define new hash key types by defining four procedures,
+initializing a \fBTcl_HashKeyType\fR structure to describe the type, and
+calling \fBTcl_InitCustomHashTable\fR. The \fBTcl_HashKeyType\fR structure is
+defined as follows:
+.PP
+.CS
+typedef struct Tcl_HashKeyType {
+    int \fIversion\fR;
+    int \fIflags\fR;
+    Tcl_HashKeyProc *\fIhashKeyProc\fR;
+    Tcl_CompareHashKeysProc *\fIcompareKeysProc\fR;
+    Tcl_AllocHashEntryProc *\fIallocEntryProc\fR;
+    Tcl_FreeHashEntryProc *\fIfreeEntryProc\fR;
+} \fBTcl_HashKeyType\fR;
+.CE
+.PP
+The \fIversion\fR member is the version of the table. If this structure is
+extended in future then the version can be used to distinguish between
+different structures. It should be set to \fBTCL_HASH_KEY_TYPE_VERSION\fR.
+.PP
+The \fIflags\fR member is 0 or one or more of the following values OR'ed
+together:
+.IP \fBTCL_HASH_KEY_RANDOMIZE_HASH\fR 25
+There are some things, pointers for example which do not hash well because
+they do not use the lower bits. If this flag is set then the hash table will
+attempt to rectify this by randomizing the bits and then using the upper N
+bits as the index into the table.
+.IP \fBTCL_HASH_KEY_SYSTEM_HASH\fR 25
+This flag forces Tcl to use the memory allocation procedures provided by the
+operating system when allocating and freeing memory used to store the hash
+table data structures, and not any of Tcl's own customized memory allocation
+routines. This is important if the hash table is to be used in the
+implementation of a custom set of allocation routines, or something that a
+custom set of allocation routines might depend on, in order to avoid any
+circular dependency.
+.PP
+The \fIhashKeyProc\fR member contains the address of a function called to
+calculate a hash value for the key.
+.PP
+.CS
+typedef unsigned int \fBTcl_HashKeyProc\fR(
+        Tcl_HashTable *\fItablePtr\fR,
+        void *\fIkeyPtr\fR);
+.CE
+.PP
+If this is NULL then \fIkeyPtr\fR is used and
+\fBTCL_HASH_KEY_RANDOMIZE_HASH\fR is assumed.
+.PP
+The \fIcompareKeysProc\fR member contains the address of a function called to
+compare two keys.
+.PP
+.CS
+typedef int \fBTcl_CompareHashKeysProc\fR(
+        void *\fIkeyPtr\fR,
+        Tcl_HashEntry *\fIhPtr\fR);
+.CE
+.PP
+If this is NULL then the \fIkeyPtr\fR pointers are compared. If the keys do
+not match then the function returns 0, otherwise it returns 1.
+.PP
+The \fIallocEntryProc\fR member contains the address of a function called to
+allocate space for an entry and initialize the key and clientData.
+.PP
+.CS
+typedef Tcl_HashEntry *\fBTcl_AllocHashEntryProc\fR(
+        Tcl_HashTable *\fItablePtr\fR,
+        void *\fIkeyPtr\fR);
+.CE
+.PP
+If this is NULL then \fBTcl_Alloc\fR is used to allocate enough space for a
+Tcl_HashEntry, the key pointer is assigned to key.oneWordValue and the
+clientData is set to NULL. String keys and array keys use this function to
+allocate enough space for the entry and the key in one block, rather than
+doing it in two blocks. This saves space for a pointer to the key from the
+entry and another memory allocation. Tcl_Obj* keys use this function to
+allocate enough space for an entry and increment the reference count on the
+value.
+.PP
+The \fIfreeEntryProc\fR member contains the address of a function called to
+free space for an entry.
+.PP
+.CS
+typedef void \fBTcl_FreeHashEntryProc\fR(
+        Tcl_HashEntry *\fIhPtr\fR);
+.CE
+.PP
+If this is NULL then \fBTcl_Free\fR is used to free the space for the entry.
+Tcl_Obj* keys use this function to decrement the reference count on the
+value.

+.BE
+.SH INTRODUCTION
+.PP
+The Tcl stubs mechanism defines a way to dynamically bind
+extensions to a particular Tcl implementation at run time.
+This provides two significant benefits to Tcl users:
+.IP 1) 5
+Extensions that use the stubs mechanism can be loaded into
+multiple versions of Tcl without being recompiled or
+relinked.
+.IP 2) 5
+Extensions that use the stubs mechanism can be dynamically
+loaded into statically-linked Tcl applications.
+.PP
+The stubs mechanism accomplishes this by exporting function tables
+that define an interface to the Tcl API.  The extension then accesses
+the Tcl API through offsets into the function table, so there are no
+direct references to any of the Tcl library's symbols.  This
+redirection is transparent to the extension, so an extension writer
+can continue to use all public Tcl functions as documented.
+.PP
+The stubs mechanism requires no changes to applications incorporating
+Tcl interpreters.  Only developers creating C-based Tcl extensions
+need to take steps to use the stubs mechanism with their extensions.
+.PP
+Enabling the stubs mechanism for an extension requires the following
+steps:
+.IP 1) 5
+Call \fBTcl_InitStubs\fR in the extension before calling any other
+Tcl functions.
+.IP 2) 5
+Define the \fBUSE_TCL_STUBS\fR symbol.  Typically, you would include the
+\fB\-DUSE_TCL_STUBS\fR flag when compiling the extension.
+.IP 3) 5
+Link the extension with the Tcl stubs library instead of the standard
+Tcl library.  For example, to use the Tcl 8.6 ABI on Unix platforms,
+the library name is \fIlibtclstub8.6.a\fR; on Windows platforms, the
+library name is \fItclstub86.lib\fR.
+.PP
+If the extension also requires the Tk API, it must also call
+\fBTk_InitStubs\fR to initialize the Tk stubs interface and link
+with the Tk stubs libraries.  See the \fBTk_InitStubs\fR page for
+more information.
+.SH DESCRIPTION
+\fBTcl_InitStubs\fR attempts to initialize the stub table pointers
+and ensure that the correct version of Tcl is loaded.  In addition
+to an interpreter handle, it accepts as arguments a version number
+and a Boolean flag indicating whether the extension requires
+an exact version match or not.  If \fIexact\fR is 0, then the
+extension is indicating that newer versions of Tcl are acceptable
+as long as they have the same major version number as \fIversion\fR;
+non-zero means that only the specified \fIversion\fR is acceptable.
+\fBTcl_InitStubs\fR returns a string containing the actual version
+of Tcl satisfying the request, or NULL if the Tcl version is not
+acceptable, does not support stubs, or any other error condition occurred.

+.BE
+.SH DESCRIPTION
+.PP
+These procedures are used to create, modify, and read Tcl values
+that hold integral values.  
+.PP
+The different routines exist to accommodate different integral types in C
+with which values might be exchanged.  The C integral types for which Tcl
+provides value exchange routines are \fBint\fR, \fBlong int\fR,
+\fBTcl_WideInt\fR, and \fBmp_int\fR.  The \fBint\fR and \fBlong int\fR types
+are provided by the C language standard.  The \fBTcl_WideInt\fR type is a
+typedef defined to be whatever signed integral type covers at least the
+64-bit integer range (-9223372036854775808 to 9223372036854775807).  Depending
+on the platform and the C compiler, the actual type might be
+\fBlong int\fR, \fBlong long int\fR, \fBint64\fR, or something else.
+The \fBmp_int\fR type is a multiple-precision integer type defined
+by the LibTomMath multiple-precision integer library.  
+.PP
+The \fBTcl_NewIntObj\fR, \fBTcl_NewLongObj\fR, \fBTcl_NewWideIntObj\fR,
+and \fBTcl_NewBignumObj\fR routines each create and return a new
+Tcl value initialized to the integral value of the argument.  The
+returned Tcl value is unshared.
+.PP
+The \fBTcl_SetIntObj\fR, \fBTcl_SetLongObj\fR, \fBTcl_SetWideIntObj\fR,
+and \fBTcl_SetBignumObj\fR routines each set the value of an existing
+Tcl value pointed to by \fIobjPtr\fR to the integral value provided
+by the other argument.  The \fIobjPtr\fR argument must point to an
+unshared Tcl value.  Any attempt to set the value of a shared Tcl value
+violates Tcl's copy-on-write policy.  Any existing string representation
+or internal representation in the unshared Tcl value will be freed
+as a consequence of setting the new value.
+.PP
+The \fBTcl_GetIntFromObj\fR, \fBTcl_GetLongFromObj\fR,
+\fBTcl_GetWideIntFromObj\fR, \fBTcl_GetBignumFromObj\fR, and
+\fBTcl_TakeBignumFromObj\fR routines attempt to retrieve an integral
+value of the appropriate type from the Tcl value \fIobjPtr\fR.  If the
+attempt succeeds, then \fBTCL_OK\fR is returned, and the value is
+written to the storage provided by the caller.  The attempt might
+fail if \fIobjPtr\fR does not hold an integral value, or if the
+value exceeds the range of the target type.  If the attempt fails,
+then \fBTCL_ERROR\fR is returned, and if \fIinterp\fR is non-NULL,
+an error message is left in \fIinterp\fR.  The \fBTcl_ObjType\fR
+of \fIobjPtr\fR may be changed to make subsequent calls to the
+same routine more efficient. Unlike the other functions,
+\fBTcl_TakeBignumFromObj\fR may set the content of the Tcl value
+\fIobjPtr\fR to an empty string in the process of retrieving the
+multiple-precision integer value.
+.PP
+The choice between \fBTcl_GetBignumFromObj\fR and
+\fBTcl_TakeBignumFromObj\fR is governed by how the caller will
+continue to use \fIobjPtr\fR.  If after the \fBmp_int\fR value
+is retrieved from \fIobjPtr\fR, the caller will make no more
+use of \fIobjPtr\fR, then using \fBTcl_TakeBignumFromObj\fR
+permits Tcl to detect when an unshared \fIobjPtr\fR permits the
+value to be moved instead of copied, which should be more efficient.
+If anything later in the caller requires
+\fIobjPtr\fR to continue to hold the same value, then
+\fBTcl_GetBignumFromObj\fR must be chosen.
+.PP
+The \fBTcl_InitBignumFromDouble\fR routine is a utility procedure
+that extracts the integer part of \fIdoubleValue\fR and stores that
+integer value in the \fBmp_int\fR value \fIbigValue\fR.

+.BE
+.SH DESCRIPTION
+.PP
+The \fBTcl_CreateInterp\fR procedure returns a pointer to a Tcl_Interp
+structure.  Callers of \fBTcl_CreateInterp\fR should use this pointer
+as an opaque token, suitable for nothing other than passing back to
+other routines in the Tcl interface.  Accessing fields directly through
+the pointer as described below is no longer supported.  The supported
+public routines \fBTcl_SetResult\fR, \fBTcl_GetResult\fR,
+\fBTcl_SetErrorLine\fR, \fBTcl_GetErrorLine\fR must be used instead.
+.PP
+For legacy programs and extensions no longer being maintained, compiles
+against the Tcl 8.6 header files are only possible with the compiler
+directives
+.CS
+#define USE_INTERP_RESULT
+.CE
+and/or
+.CS
+#define USE_INTERP_ERRORLINE
+.CE
+depending on which fields of the \fBTcl_Interp\fR struct are accessed.
+These directives may be embedded in code or supplied via compiler options.
+.PP
+The \fIresult\fR and \fIfreeProc\fR fields are used to return
+results or error messages from commands.
+This information is returned by command procedures back to \fBTcl_Eval\fR,
+and by \fBTcl_Eval\fR back to its callers.
+The \fIresult\fR field points to the string that represents the
+result or error message, and the \fIfreeProc\fR field tells how
+to dispose of the storage for the string when it is not needed anymore.
+The easiest way for command procedures to manipulate these
+fields is to call procedures like \fBTcl_SetResult\fR
+or \fBTcl_AppendResult\fR;  they
+will hide all the details of managing the fields.
+The description below is for those procedures that manipulate the
+fields directly.
+.PP
+Whenever a command procedure returns, it must ensure
+that the \fIresult\fR field of its interpreter points to the string
+being returned by the command.
+The \fIresult\fR field must always point to a valid string.
+If a command wishes to return no result then \fIinterp->result\fR
+should point to an empty string.
+Normally, results are assumed to be statically allocated,
+which means that the contents will not change before the next time
+\fBTcl_Eval\fR is called or some other command procedure is invoked.
+In this case, the \fIfreeProc\fR field must be zero.
+Alternatively, a command procedure may dynamically
+allocate its return value (e.g. using \fBTcl_Alloc\fR)
+and store a pointer to it in \fIinterp->result\fR.
+In this case, the command procedure must also set \fIinterp->freeProc\fR
+to the address of a procedure that can free the value, or \fBTCL_DYNAMIC\fR
+if the storage was allocated directly by Tcl or by a call to
+\fBTcl_Alloc\fR. 
+If \fIinterp->freeProc\fR is non-zero, then Tcl will call \fIfreeProc\fR
+to free the space pointed to by \fIinterp->result\fR before it
+invokes the next command.
+If a client procedure overwrites \fIinterp->result\fR when
+\fIinterp->freeProc\fR is non-zero, then it is responsible for calling
+\fIfreeProc\fR to free the old \fIinterp->result\fR (the \fBTcl_FreeResult\fR
+macro should be used for this purpose).
+.PP
+\fIFreeProc\fR should have arguments and result that match the
+\fBTcl_FreeProc\fR declaration above:  it receives a single
+argument which is a pointer to the result value to free.
+In most applications \fBTCL_DYNAMIC\fR is the only non-zero value ever
+used for \fIfreeProc\fR.
+However, an application may store a different procedure address
+in \fIfreeProc\fR in order to use an alternate memory allocator
+or in order to do other cleanup when the result memory is freed.
+.PP
+As part of processing each command, \fBTcl_Eval\fR initializes
+\fIinterp->result\fR
+and \fIinterp->freeProc\fR just before calling the command procedure for
+the command.  The \fIfreeProc\fR field will be initialized to zero,
+and \fIinterp->result\fR will point to an empty string.  Commands that
+do not return any value can simply leave the fields alone.
+Furthermore, the empty string pointed to by \fIresult\fR is actually
+part of an array of \fBTCL_RESULT_SIZE\fR characters (approximately 200).
+If a command wishes to return a short string, it can simply copy
+it to the area pointed to by \fIinterp->result\fR.  Or, it can use
+the sprintf procedure to generate a short result string at the location
+pointed to by \fIinterp->result\fR.
+.PP
+It is a general convention in Tcl-based applications that the result
+of an interpreter is normally in the initialized state described
+in the previous paragraph.
+Procedures that manipulate an interpreter's result (e.g. by
+returning an error) will generally assume that the result
+has been initialized when the procedure is called.
+If such a procedure is to be called after the result has been
+changed, then \fBTcl_ResetResult\fR should be called first to
+reset the result to its initialized state.  The direct use of
+\fIinterp->result\fR is strongly deprecated (see \fBTcl_SetResult\fR).
+.PP
+The \fIerrorLine\fR
+field is valid only after \fBTcl_Eval\fR returns
+a \fBTCL_ERROR\fR return code.  In this situation the \fIerrorLine\fR
+field identifies the line number of the command being executed when
+the error occurred.  The line numbers are relative to the command
+being executed:  1 means the first line of the command passed to
+\fBTcl_Eval\fR, 2 means the second line, and so on.
+The \fIerrorLine\fR field is typically used in conjunction with
+\fBTcl_AddErrorInfo\fR to report information about where an error
+occurred.
+\fIErrorLine\fR should not normally be modified except by \fBTcl_Eval\fR.

+.BE
+.SH DESCRIPTION
+.PP
+Tcl's interpreter resource limit subsystem allows for close control
+over how much computation time a script may use, and is useful for
+cases where a program is divided into multiple pieces where some parts
+are more trusted than others (e.g. web application servers).
+.PP
+Every interpreter may have a limit on the wall-time for execution, and
+a limit on the number of commands that the interpreter may execute.
+Since checking of these limits is potentially expensive (especially
+the time limit), each limit also has a checking granularity, which is
+a divisor for an internal count of the number of points in the core
+where a check may be performed (which is immediately before executing
+a command and at an unspecified frequency between running commands,
+which can happen in empty-bodied \fBwhile\fR loops).
+.PP
+The final component of the limit engine is a callback scheme which
+allows for notifications of when a limit has been exceeded.  These
+callbacks can just provide logging, or may allocate more resources to
+the interpreter to permit it to continue processing longer.
+.PP
+When a limit is exceeded (and the callbacks have run; the order of
+execution of the callbacks is unspecified) execution in the limited
+interpreter is stopped by raising an error and setting a flag that
+prevents the \fBcatch\fR command in that interpreter from trapping
+that error.  It is up to the context that started execution in that
+interpreter (typically a master interpreter) to handle the error.
+.SH "LIMIT CHECKING API"
+.PP
+To check the resource limits for an interpreter, call
+\fBTcl_LimitCheck\fR, which returns \fBTCL_OK\fR if the limit was not
+exceeded (after processing callbacks) and \fBTCL_ERROR\fR if the limit was
+exceeded (in which case an error message is also placed in the
+interpreter result).  That function should only be called when
+\fBTcl_LimitReady\fR returns non-zero so that granularity policy is
+enforced.  This API is designed to be similar in usage to
+\fBTcl_AsyncReady\fR and \fBTcl_AsyncInvoke\fR.
+.PP
+When writing code that may behave like \fBcatch\fR in respect of
+errors, you should only trap an error if \fBTcl_LimitExceeded\fR
+returns zero.  If it returns non-zero, the interpreter is in a
+limit-exceeded state and errors should be allowed to propagate to the
+calling context.  You can also check whether a particular type of
+limit has been exceeded using \fBTcl_LimitTypeExceeded\fR.
+.SH "LIMIT CONFIGURATION"
+.PP
+To check whether a limit has been set (but not whether it has actually
+been exceeded) on an interpreter, call \fBTcl_LimitTypeEnabled\fR with
+the type of limit you want to check.  To enable a particular limit
+call \fBTcl_LimitTypeSet\fR, and to disable a limit call
+\fBTcl_LimitTypeReset\fR.
+.PP
+The level of a command limit may be set using
+\fBTcl_LimitSetCommands\fR, and retrieved using
+\fBTcl_LimitGetCommands\fR.  Similarly for a time limit with
+\fBTcl_LimitSetTime\fR and \fBTcl_LimitGetTime\fR respectively, but
+with that API the time limit is copied from and to the Tcl_Time
+structure that the \fItimeLimitPtr\fR argument points to.
+.PP
+The checking granularity for a particular limit may be set using
+\fBTcl_LimitSetGranularity\fR and retrieved using
+\fBTcl_LimitGetGranularity\fR.  Note that granularities must always be
+positive.
+.SS "LIMIT CALLBACKS"
+.PP
+To add a handler callback to be invoked when a limit is exceeded, call
+\fBTcl_LimitAddHandler\fR.  The \fIhandlerProc\fR argument describes
+the function that will actually be called; it should have the
+following prototype:
+.PP
+.CS
+typedef void \fBTcl_LimitHandlerProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR);
+.CE
+.PP
+The \fIclientData\fR argument to the handler will be whatever is
+passed to the \fIclientData\fR argument to \fBTcl_LimitAddHandler\fR,
+and the \fIinterp\fR is the interpreter that had its limit exceeded.
+.PP
+The \fIdeleteProc\fR argument to \fBTcl_LimitAddHandler\fR is a
+function to call to delete the \fIclientData\fR value.  It may be
+\fBTCL_STATIC\fR or NULL if no deletion action is necessary, or
+\fBTCL_DYNAMIC\fR if all that is necessary is to free the structure with
+\fBTcl_Free\fR.  Otherwise, it should refer to a function with the
+following prototype:
+.PP
+.CS
+typedef void \fBTcl_LimitHandlerDeleteProc\fR(
+        ClientData \fIclientData\fR);
+.CE
+.PP
+A limit handler may be deleted using \fBTcl_LimitRemoveHandler\fR; the
+handler removed will be the first one found (out of the handlers added
+with \fBTcl_LimitAddHandler\fR) with exactly matching \fItype\fR,
+\fIhandlerProc\fR and \fIclientData\fR arguments.  This function
+always invokes the \fIdeleteProc\fR on the \fIclientData\fR (unless
+the \fIdeleteProc\fR was NULL or \fBTCL_STATIC\fR).

+.BE
+.SH DESCRIPTION
+.PP
+\fBTcl_LinkVar\fR uses variable traces to keep the Tcl variable
+named by \fIvarName\fR in sync with the C variable at the address
+given by \fIaddr\fR.
+Whenever the Tcl variable is read the value of the C variable will
+be returned, and whenever the Tcl variable is written the C
+variable will be updated to have the same value.
+\fBTcl_LinkVar\fR normally returns \fBTCL_OK\fR;  if an error occurs
+while setting up the link (e.g. because \fIvarName\fR is the
+name of array) then \fBTCL_ERROR\fR is returned and the interpreter's result
+contains an error message.
+.PP
+The \fItype\fR argument specifies the type of the C variable,
+and must have one of the following values, optionally OR'ed with
+\fBTCL_LINK_READ_ONLY\fR:
+.TP
+\fBTCL_LINK_INT\fR
+The C variable is of type \fBint\fR.
+Any value written into the Tcl variable must have a proper integer
+form acceptable to \fBTcl_GetIntFromObj\fR;  attempts to write
+non-integer values into \fIvarName\fR will be rejected with
+Tcl errors.
+.TP
+\fBTCL_LINK_UINT\fR
+The C variable is of type \fBunsigned int\fR.
+Any value written into the Tcl variable must have a proper unsigned
+integer form acceptable to \fBTcl_GetWideIntFromObj\fR and in the
+platform's defined range for the \fBunsigned int\fR type; attempts to
+write non-integer values (or values outside the range) into
+\fIvarName\fR will be rejected with Tcl errors.
+.TP
+\fBTCL_LINK_CHAR\fR
+The C variable is of type \fBchar\fR.
+Any value written into the Tcl variable must have a proper integer
+form acceptable to \fBTcl_GetIntFromObj\fR and be in the range of the
+\fBchar\fR datatype; attempts to write non-integer or out-of-range
+values into \fIvarName\fR will be rejected with Tcl errors.
+.TP
+\fBTCL_LINK_UCHAR\fR
+The C variable is of type \fBunsigned char\fR.
+Any value written into the Tcl variable must have a proper unsigned
+integer form acceptable to \fBTcl_GetIntFromObj\fR and in the
+platform's defined range for the \fBunsigned char\fR type; attempts to
+write non-integer values (or values outside the range) into
+\fIvarName\fR will be rejected with Tcl errors.
+.TP
+\fBTCL_LINK_SHORT\fR
+The C variable is of type \fBshort\fR.
+Any value written into the Tcl variable must have a proper integer
+form acceptable to \fBTcl_GetIntFromObj\fR and be in the range of the
+\fBshort\fR datatype; attempts to write non-integer or out-of-range
+values into \fIvarName\fR will be rejected with Tcl errors.
+.TP
+\fBTCL_LINK_USHORT\fR
+The C variable is of type \fBunsigned short\fR.
+Any value written into the Tcl variable must have a proper unsigned
+integer form acceptable to \fBTcl_GetIntFromObj\fR and in the
+platform's defined range for the \fBunsigned short\fR type; attempts to
+write non-integer values (or values outside the range) into
+\fIvarName\fR will be rejected with Tcl errors.
+.TP
+\fBTCL_LINK_LONG\fR
+The C variable is of type \fBlong\fR.
+Any value written into the Tcl variable must have a proper integer
+form acceptable to \fBTcl_GetLongFromObj\fR; attempts to write
+non-integer or out-of-range
+values into \fIvarName\fR will be rejected with Tcl errors.
+.TP
+\fBTCL_LINK_ULONG\fR
+The C variable is of type \fBunsigned long\fR.
+Any value written into the Tcl variable must have a proper unsigned
+integer form acceptable to \fBTcl_GetWideIntFromObj\fR and in the
+platform's defined range for the \fBunsigned long\fR type; attempts to
+write non-integer values (or values outside the range) into
+\fIvarName\fR will be rejected with Tcl errors.
+.TP
+\fBTCL_LINK_DOUBLE\fR
+The C variable is of type \fBdouble\fR.
+Any value written into the Tcl variable must have a proper real
+form acceptable to \fBTcl_GetDoubleFromObj\fR;  attempts to write
+non-real values into \fIvarName\fR will be rejected with
+Tcl errors.
+.TP
+\fBTCL_LINK_FLOAT\fR
+The C variable is of type \fBfloat\fR.
+Any value written into the Tcl variable must have a proper real
+form acceptable to \fBTcl_GetDoubleFromObj\fR and must be within the
+range acceptable for a \fBfloat\fR; attempts to
+write non-real values (or values outside the range) into
+\fIvarName\fR will be rejected with Tcl errors.
+.TP
+\fBTCL_LINK_WIDE_INT\fR
+The C variable is of type \fBTcl_WideInt\fR (which is an integer type
+at least 64-bits wide on all platforms that can support it.)
+Any value written into the Tcl variable must have a proper integer
+form acceptable to \fBTcl_GetWideIntFromObj\fR;  attempts to write
+non-integer values into \fIvarName\fR will be rejected with
+Tcl errors.
+.TP
+\fBTCL_LINK_WIDE_UINT\fR
+The C variable is of type \fBTcl_WideUInt\fR (which is an unsigned
+integer type at least 64-bits wide on all platforms that can support
+it.)
+Any value written into the Tcl variable must have a proper unsigned
+integer form acceptable to \fBTcl_GetWideIntFromObj\fR (it will be
+cast to unsigned);
+.\" FIXME! Use bignums instead.
+attempts to write non-integer values into \fIvarName\fR will be
+rejected with Tcl errors.
+.TP
+\fBTCL_LINK_BOOLEAN\fR
+The C variable is of type \fBint\fR.
+If its value is zero then it will read from Tcl as
+.QW 0 ;
+otherwise it will read from Tcl as
+.QW 1 .
+Whenever \fIvarName\fR is
+modified, the C variable will be set to a 0 or 1 value.
+Any value written into the Tcl variable must have a proper boolean
+form acceptable to \fBTcl_GetBooleanFromObj\fR;  attempts to write
+non-boolean values into \fIvarName\fR will be rejected with
+Tcl errors.
+.TP
+\fBTCL_LINK_STRING\fR
+The C variable is of type \fBchar *\fR.
+If its value is not NULL then it must be a pointer to a string
+allocated with \fBTcl_Alloc\fR or \fBckalloc\fR.
+Whenever the Tcl variable is modified the current C string will be
+freed and new memory will be allocated to hold a copy of the variable's
+new value.
+If the C variable contains a NULL pointer then the Tcl variable
+will read as
+.QW NULL .
+.PP
+If the \fBTCL_LINK_READ_ONLY\fR flag is present in \fItype\fR then the
+variable will be read-only from Tcl, so that its value can only be
+changed by modifying the C variable.
+Attempts to write the variable from Tcl will be rejected with errors.
+.PP
+\fBTcl_UnlinkVar\fR removes the link previously set up for the
+variable given by \fIvarName\fR.  If there does not exist a link
+for \fIvarName\fR then the procedure has no effect.
+.PP
+\fBTcl_UpdateLinkedVar\fR may be invoked after the C variable has
+changed to force the Tcl variable to be updated immediately.
+In many cases this procedure is not needed, since any attempt to
+read the Tcl variable will return the latest value of the C variable.
+However, if a trace has been set on the Tcl variable (such as a
+Tk widget that wishes to display the value of the variable), the
+trace will not trigger when the C variable has changed.
+\fBTcl_UpdateLinkedVar\fR ensures that any traces on the Tcl
+variable are invoked.
+.PP
+Note that, as with any call to a Tcl interpreter, \fBTcl_UpdateLinkedVar\fR
+must be called from the same thread that created the interpreter. The safest
+mechanism is to ensure that the C variable is only ever updated from the same
+thread that created the interpreter (possibly in response to an event posted
+with \fBTcl_ThreadQueueEvent\fR), but when it is necessary to update the
+variable in a separate thread, it is advised that \fBTcl_AsyncMark\fR be used
+to indicate to the thread hosting the interpreter that it is ready to run
+\fBTcl_UpdateLinkedVar\fR.

+the efficient indexing and appending.
+The procedures described in this man page are used to
+create, modify, index, and append to Tcl list values from C code.
+.PP
+\fBTcl_ListObjAppendList\fR and \fBTcl_ListObjAppendElement\fR
+both add one or more values
+to the end of the list value referenced by \fIlistPtr\fR.
+\fBTcl_ListObjAppendList\fR appends each element of the list value
+referenced by \fIelemListPtr\fR while
+\fBTcl_ListObjAppendElement\fR appends the single value
+referenced by \fIobjPtr\fR.
+Both procedures will convert the value referenced by \fIlistPtr\fR
+to a list value if necessary.
+If an error occurs during conversion,
+both procedures return \fBTCL_ERROR\fR and leave an error message
+in the interpreter's result value if \fIinterp\fR is not NULL.
+Similarly, if \fIelemListPtr\fR does not already refer to a list value,
+\fBTcl_ListObjAppendList\fR will attempt to convert it to one
+and if an error occurs during conversion,
+will return \fBTCL_ERROR\fR
+and leave an error message in the interpreter's result value
+if interp is not NULL.
+Both procedures invalidate any old string representation of \fIlistPtr\fR
+and, if it was converted to a list value,
+free any old internal representation.
+Similarly, \fBTcl_ListObjAppendList\fR frees any old internal representation
+of \fIelemListPtr\fR if it converts it to a list value.
+After appending each element in \fIelemListPtr\fR,
+\fBTcl_ListObjAppendList\fR increments the element's reference count
+since \fIlistPtr\fR now also refers to it.
+For the same reason, \fBTcl_ListObjAppendElement\fR
+increments \fIobjPtr\fR's reference count.
+If no error occurs,
+the two procedures return \fBTCL_OK\fR after appending the values.
+.PP
+\fBTcl_NewListObj\fR and \fBTcl_SetListObj\fR
+create a new value or modify an existing value to hold 
+the \fIobjc\fR elements of the array referenced by \fIobjv\fR
+where each element is a pointer to a Tcl value.
+If \fIobjc\fR is less than or equal to zero,
+they return an empty value.
+The new value's string representation is left invalid.
+The two procedures increment the reference counts
+of the elements in \fIobjc\fR since the list value now refers to them.
+The new list value returned by \fBTcl_NewListObj\fR
+has reference count zero.
+.PP
+\fBTcl_ListObjGetElements\fR returns a count and a pointer to an array of
+the elements in a list value.  It returns the count by storing it in the
+address \fIobjcPtr\fR.  Similarly, it returns the array pointer by storing
+it in the address \fIobjvPtr\fR.
+The memory pointed to is managed by Tcl and should not be freed or written
+to by the caller. If the list is empty, 0 is stored at \fIobjcPtr\fR
+and NULL at \fIobjvPtr\fR.
+If \fIlistPtr\fR is not already a list value, \fBTcl_ListObjGetElements\fR
+will attempt to convert it to one; if the conversion fails, it returns
+\fBTCL_ERROR\fR and leaves an error message in the interpreter's result
+value if \fIinterp\fR is not NULL.
+Otherwise it returns \fBTCL_OK\fR after storing the count and array pointer.
+.PP
+\fBTcl_ListObjLength\fR returns the number of elements in the list value
+referenced by \fIlistPtr\fR.
+It returns this count by storing an integer in the address \fIintPtr\fR.
+If the value is not already a list value,
+\fBTcl_ListObjLength\fR will attempt to convert it to one;
+if the conversion fails, it returns \fBTCL_ERROR\fR
+and leaves an error message in the interpreter's result value
+if \fIinterp\fR is not NULL.
+Otherwise it returns \fBTCL_OK\fR after storing the list's length.
+.PP
+The procedure \fBTcl_ListObjIndex\fR returns a pointer to the value
+at element \fIindex\fR in the list referenced by \fIlistPtr\fR.
+It returns this value by storing a pointer to it
+in the address \fIobjPtrPtr\fR.
+If \fIlistPtr\fR does not already refer to a list value,
+\fBTcl_ListObjIndex\fR will attempt to convert it to one;
+if the conversion fails, it returns \fBTCL_ERROR\fR
+and leaves an error message in the interpreter's result value
+if \fIinterp\fR is not NULL.
+If the index is out of range,
+that is, \fIindex\fR is negative or
+greater than or equal to the number of elements in the list,
+\fBTcl_ListObjIndex\fR stores a NULL in \fIobjPtrPtr\fR
+and returns \fBTCL_OK\fR.
+Otherwise it returns \fBTCL_OK\fR after storing the element's
+value pointer.
+The reference count for the list element is not incremented;
+the caller must do that if it needs to retain a pointer to the element.
+.PP
+\fBTcl_ListObjReplace\fR replaces zero or more elements
+of the list referenced by \fIlistPtr\fR
+with the \fIobjc\fR values in the array referenced by \fIobjv\fR.
+If \fIlistPtr\fR does not point to a list value,
+\fBTcl_ListObjReplace\fR will attempt to convert it to one;
+if the conversion fails, it returns \fBTCL_ERROR\fR
+and leaves an error message in the interpreter's result value
+if \fIinterp\fR is not NULL.
+Otherwise, it returns \fBTCL_OK\fR after replacing the values.
+If \fIobjv\fR is NULL, no new elements are added.
+If the argument \fIfirst\fR is zero or negative,
+it refers to the first element.
+If \fIfirst\fR is greater than or equal to the
+number of elements in the list, then no elements are deleted;
+the new elements are appended to the list.
+\fIcount\fR gives the number of elements to replace.
+If \fIcount\fR is zero or negative then no elements are deleted;
+the new elements are simply inserted before the one
+designated by \fIfirst\fR.
+\fBTcl_ListObjReplace\fR invalidates \fIlistPtr\fR's
+old string representation.
+The reference counts of any elements inserted from \fIobjv\fR
+are incremented since the resulting list now refers to them.
+Similarly, the reference counts for any replaced values are decremented.
+.PP
+Because \fBTcl_ListObjReplace\fR combines
+both element insertion and deletion,
+it can be used to implement a number of list operations.
+For example, the following code inserts the \fIobjc\fR values
+referenced by the array of value pointers \fIobjv\fR
+just before the element \fIindex\fR of the list referenced by \fIlistPtr\fR:
+.PP
+.CS
+result = \fBTcl_ListObjReplace\fR(interp, listPtr, index, 0,
+        objc, objv);
+.CE
+.PP
+Similarly, the following code appends the \fIobjc\fR values
+referenced by the array \fIobjv\fR
+to the end of the list \fIlistPtr\fR:
+.PP
+.CS
+result = \fBTcl_ListObjLength\fR(interp, listPtr, &length);
+if (result == TCL_OK) {
+    result = \fBTcl_ListObjReplace\fR(interp, listPtr, length, 0,
+            objc, objv);
+}
+.CE
+.PP
+The \fIcount\fR list elements starting at \fIfirst\fR can be deleted
+by simply calling \fBTcl_ListObjReplace\fR
+with a NULL \fIobjvPtr\fR:
+.PP
+.CS
+result = \fBTcl_ListObjReplace\fR(interp, listPtr, first, count,
+        0, NULL);

+.SH DESCRIPTION
+.PP
+\fBTcl_LoadFile\fR loads a file from the filesystem (including potentially any
+virtual filesystem that has been installed) and provides a handle to it that
+may be used in further operations. The \fIsymbols\fR array, if non-NULL,
+supplies a set of names of symbols (typically functions) that must be resolved
+from the library and which will be stored in the array indicated by
+\fIprocPtrs\fR. If any of the symbols is not resolved, the loading of the file
+will fail with an error message left in the interpreter (if that is non-NULL).
+The result of \fBTcl_LoadFile\fR is a standard Tcl error code. The library may
+be unloaded with \fBTcl_FSUnloadFile\fR.
+.PP
+\fBTcl_FindSymbol\fR locates a symbol in a loaded library and returns it. If
+the symbol cannot be found, it returns NULL and sets an error message in the
+given \fIinterp\fR (if that is non-NULL). Note that it is unsafe to use this
+operation on a handle that has been passed to \fBTcl_FSUnloadFile\fR.

+.SH DESCRIPTION
+.PP
+A method is an operation carried out on an object that is associated with the
+object. Every method must be attached to either an object or a class; methods
+attached to a class are associated with all instances (direct and indirect) of
+that class.
+.PP
+Given a method, the entity that declared it can be found using
+\fBTcl_MethodDeclarerClass\fR which returns the class that the method is
+attached to (or NULL if the method is not attached to any class) and
+\fBTcl_MethodDeclarerObject\fR which returns the object that the method is
+attached to (or NULL if the method is not attached to an object). The name of
+the method can be retrieved with \fBTcl_MethodName\fR and whether the method
+is exported is retrieved with \fBTcl_MethodIsPublic\fR. The type of the method
+can also be introspected upon to a limited degree; the function
+\fBTcl_MethodIsType\fR returns whether a method is of a particular type,
+assigning the per-method \fIclientData\fR to the variable pointed to by
+\fIclientDataPtr\fR if (that is non-NULL) if the type is matched.
+.SS "METHOD CREATION"
+.PP
+Methods are created by \fBTcl_NewMethod\fR and \fBTcl_NewInstanceMethod\fR,
+which
+create a method attached to a class or an object respectively. In both cases,
+the \fInameObj\fR argument gives the name of the method to create, the
+\fIisPublic\fR argument states whether the method should be exported
+initially, the \fImethodTypePtr\fR argument describes the implementation of
+the method (see the \fBMETHOD TYPES\fR section below) and the \fIclientData\fR
+argument gives some implementation-specific data that is passed on to the
+implementation of the method when it is called.
+.PP
+When the \fInameObj\fR argument to \fBTcl_NewMethod\fR is NULL, an
+unnamed method is created, which is used for constructors and destructors.
+Constructors should be installed into their class using the
+\fBTcl_ClassSetConstructor\fR function, and destructors (which must not
+require any arguments) should be installed into their class using the
+\fBTcl_ClassSetDestructor\fR function. Unnamed methods should not be used for
+any other purpose, and named methods should not be used as either constructors
+or destructors. Also note that a NULL \fImethodTypePtr\fR is used to provide
+internal signaling, and should not be used in client code.
+.SS "METHOD CALL CONTEXTS"
+.PP
+When a method is called, a method-call context reference is passed in as one
+of the arguments to the implementation function. This context can be inspected
+to provide information about the caller, but should not be retained beyond the
+moment when the method call terminates.
+.PP
+The method that is being called can be retrieved from the context by using
+\fBTcl_ObjectContextMethod\fR, and the object that caused the method to be
+invoked can be retrieved with \fBTcl_ObjectContextObject\fR. The number of
+arguments that are to be skipped (e.g. the object name and method name in a
+normal method call) is read with \fBTcl_ObjectContextSkippedArgs\fR, and the
+context can also report whether it is working as a filter for another method
+through \fBTcl_ObjectContextIsFiltering\fR.
+.PP
+During the execution of a method, the method implementation may choose to
+invoke the stages of the method call chain that come after the current method
+implementation. This (the core of the \fBnext\fR command) is done using
+\fBTcl_ObjectContextInvokeNext\fR. Note that this function does not manipulate
+the call-frame stack, unlike the \fBnext\fR command; if the method
+implementation has pushed one or more extra frames on the stack as part of its
+implementation, it is also responsible for temporarily popping those frames
+from the stack while the \fBTcl_ObjectContextInvokeNext\fR function is
+executing. Note also that the method-call context is \fInever\fR deleted
+during the execution of this function.
+.SH "METHOD TYPES"
+.PP
+The types of methods are described by a pointer to a Tcl_MethodType structure,
+which is defined as:
+.PP
+.CS
+typedef struct {
+    int \fIversion\fR;
+    const char *\fIname\fR;
+    Tcl_MethodCallProc *\fIcallProc\fR;
+    Tcl_MethodDeleteProc *\fIdeleteProc\fR;
+    Tcl_CloneProc *\fIcloneProc\fR;
+} \fBTcl_MethodType\fR;
+.CE
+.PP
+The \fIversion\fR field allows for future expansion of the structure, and
+should always be declared equal to TCL_OO_METHOD_VERSION_CURRENT. The
+\fIname\fR field provides a human-readable name for the type, and is reserved
+for debugging.
+.PP
+The \fIcallProc\fR field gives a function that is called when the method is
+invoked; it must never be NULL.
+.PP
+The \fIdeleteProc\fR field gives a function that is used to delete a
+particular method, and is called when the method is replaced or removed; if
+the field is NULL, it is assumed that the method's \fIclientData\fR needs no
+special action to delete.
+.PP
+The \fIcloneProc\fR field is either a function that is used to copy a method's
+\fIclientData\fR (as part of \fBTcl_CopyObjectInstance\fR) or NULL to indicate
+that the \fIclientData\fR can just be copied directly.
+.SS "TCL_METHODCALLPROC FUNCTION SIGNATURE"
+.PP
+Functions matching this signature are called when the method is invoked.
+.PP
+.CS
+typedef int \fBTcl_MethodCallProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        Tcl_ObjectContext \fIobjectContext\fR,
+        int \fIobjc\fR,
+        Tcl_Obj *const *\fIobjv\fR);
+.CE
+.PP
+The \fIclientData\fR argument to a Tcl_MethodCallProc is the value that was
+given when the method was created, the \fIinterp\fR is a place in which to
+execute scripts and access variables as well as being where to put the result
+of the method, and the \fIobjc\fR and \fIobjv\fR fields give the parameter
+objects to the method. The calling context of the method can be discovered
+through the \fIobjectContext\fR argument, and the return value from a
+Tcl_MethodCallProc is any Tcl return code (e.g. TCL_OK, TCL_ERROR).
+.SS "TCL_METHODDELETEPROC FUNCTION SIGNATURE"
+.PP
+Functions matching this signature are used when a method is deleted, whether
+through a new method being created or because the object or class is deleted.
+.PP
+.CS
+typedef void \fBTcl_MethodDeleteProc\fR(
+        ClientData \fIclientData\fR);
+.CE
+.PP
+The \fIclientData\fR argument to a Tcl_MethodDeleteProc will be the same as
+the value passed to the \fIclientData\fR argument to \fBTcl_NewMethod\fR or
+\fBTcl_NewInstanceMethod\fR when the method was created.
+.SS "TCL_CLONEPROC FUNCTION SIGNATURE"
+.PP
+Functions matching this signature are used to copy a method when the object or
+class is copied using \fBTcl_CopyObjectInstance\fR (or \fBoo::copy\fR).
+.PP
+.CS
+typedef int \fBTcl_CloneProc\fR(
+        Tcl_Interp *\fIinterp\fR,
+        ClientData \fIoldClientData\fR,
+        ClientData *\fInewClientDataPtr\fR);
+.CE
+.PP
+The \fIinterp\fR argument gives a place to write an error message when the
+attempt to clone the object is to fail, in which case the clone procedure must
+also return TCL_ERROR; it should return TCL_OK otherwise.
+The \fIoldClientData\fR field to a Tcl_CloneProc gives the value from the
+method being copied from, and the \fInewClientDataPtr\fR field will point to
+a variable in which to write the value for the method being copied to.

+to the function designated by \fIpostProcPtr\fR when it is invoked.
+.BE
+.SH DESCRIPTION
+.PP 
+This series of C functions provides an interface whereby commands that
+are implemented in C can be evaluated, and invoke Tcl commands scripts
+and scripts, without consuming space on the C stack. The non-recursive
+evaluation is done by installing a \fItrampoline\fR, a small piece of
+code that invokes a command or script, and then executes a series of
+callbacks when the command or script returns. 
+.PP
+The \fBTcl_NRCreateCommand\fR function creates a Tcl command in the
+interpreter designated by \fIinterp\fR that is prepared to handle
+nonrecursive evaluation with a trampoline. The \fIcmdName\fR argument
+gives the name of the new command. If \fIcmdName\fR contains any
+namespace qualifiers, then the new command is added to the specified
+namespace; otherwise, it is added to the global namespace. \fIproc\fR
+gives the procedure that will be called when the interpreter wishes to
+evaluate the command in an unoptimized manner, and \fInreProc\fR is
+the procedure that will be called when the interpreter wishes to
+evaluate the command using a trampoline. \fIdeleteProc\fR is a
+function that will be called before the command is deleted from the
+interpreter. When any of the three functions is invoked, it is passed
+the \fIclientData\fR parameter.
+.PP
+\fBTcl_NRCreateCommand\fR deletes any existing command
+\fIname\fR already associated with the interpreter
+(however see below for an exception where the existing command
+is not deleted).
+It returns a token that may be used to refer
+to the command in subsequent calls to \fBTcl_GetCommandName\fR.
+If \fBTcl_NRCreateCommand\fR is called for an interpreter that is in
+the process of being deleted, then it does not create a new command,
+does not delete any existing command of the same name, and returns NULL.
+.PP
+The \fIproc\fR and \fInreProc\fR function are expected to conform to
+all the rules set forth for the \fIproc\fR argument to
+\fBTcl_CreateObjCommand\fR(3) (\fIq.v.\fR).
+.PP
+When a command that is written to cope with evaluation via trampoline
+is invoked without a trampoline on the stack, it will usually respond
+to the invocation by creating a trampoline and calling the
+trampoline-enabled implementation of the same command. This call is done by
+means of \fBTcl_NRCallObjProc\fR. In the call to
+\fBTcl_NRCallObjProc\fR, the \fIinterp\fR, \fIclientData\fR,
+\fIobjc\fR and \fIobjv\fR parameters should be the same ones that were
+passed to \fIproc\fR. The \fInreProc\fR parameter should designate the
+trampoline-enabled implementation of the command.
+.PP
+\fBTcl_NREvalObj\fR arranges for the script contained in \fIobjPtr\fR
+to be evaluated in the interpreter designated by \fIinterp\fR after
+the current command (which must be trampoline-enabled) returns. It is
+the method by which a command may invoke a script without consuming
+space on the C stack. Similarly, \fBTcl_NREvalObjv\fR arranges to
+invoke a single Tcl command whose words have already been separated
+and substituted. The \fIobjc\fR and \fIobjv\fR parameters give the
+words of the command to be evaluated when execution reaches the
+trampoline.
+.PP
+\fBTcl_NRCmdSwap\fR allows for trampoline evaluation of a command whose
+resolution is already known.  The \fIcmd\fR parameter gives a
+\fBTcl_Command\fR token (returned from \fBTcl_CreateObjCommand\fR or
+\fBTcl_GetCommandFromObj\fR) identifying the command to be invoked in
+the trampoline; this command must match the word in \fIobjv[0]\fR.
+The remaining arguments are as for \fBTcl_NREvalObj\fR.
+.PP
+\fBTcl_NREvalObj\fR, \fBTcl_NREvalObjv\fR and \fBTcl_NRCmdSwap\fR
+all accept a \fIflags\fR parameter, which is an OR-ed-together set of
+bits to control evaluation. At the present time, the only supported flag
+available to callers is \fBTCL_EVAL_GLOBAL\fR. 
+.\" TODO: Again, this is a lie. Do we want to explain TCL_EVAL_INVOKE
+.\"       and TCL_EVAL_NOERR?
+If the \fBTCL_EVAL_GLOBAL\fR flag is set, the script or command is
+evaluated in the global namespace. If it is not set, it is evaluated
+in the current namespace.
+.PP
+\fBTcl_NRExprObj\fR arranges for the expression contained in \fIobjPtr\fR
+to be evaluated in the interpreter designated by \fIinterp\fR after
+the current command (which must be trampoline-enabled) returns. It is
+the method by which a command may evaluate a Tcl expression without consuming
+space on the C stack.  The argument \fIresultPtr\fR is a pointer to an
+unshared Tcl_Obj where the result of expression evaluation is to be written.
+If expression evaluation returns any code other than TCL_OK, the
+\fIresultPtr\fR value is left untouched.
+.PP
+All of the routines return \fBTCL_OK\fR if command or expression invocation
+has been scheduled successfully. If for any reason the scheduling cannot
+be completed (for example, if the interpreter is unable to find
+the requested command), they return \fBTCL_ERROR\fR with an
+appropriate message left in the interpreter's result.
+.PP
+\fBTcl_NRAddCallback\fR arranges to have a C function called when the
+current trampoline-enabled command in the Tcl interpreter designated
+by \fIinterp\fR returns.  The \fIpostProcPtr\fR argument is a pointer
+to the callback function, which must have arguments and return value
+consistent with the \fBTcl_NRPostProc\fR data type:
+.PP
+.CS
+typedef int
+\fBTcl_NRPostProc\fR(
+        \fBClientData\fR \fIdata\fR[],
+        \fBTcl_Interp\fR *\fIinterp\fR,
+        int \fIresult\fR);
+.CE
+.PP
+When the trampoline invokes the callback function, the \fIdata\fR
+parameter will point to an array containing the four one-word
+quantities that were passed to \fBTcl_NRAddCallback\fR in the
+\fIdata0\fR through \fIdata3\fR parameters. The Tcl interpreter will
+be designated by the \fIinterp\fR parameter, and the \fIresult\fR
+parameter will contain the result (\fBTCL_OK\fR, \fBTCL_ERROR\fR,
+\fBTCL_RETURN\fR, \fBTCL_BREAK\fR or \fBTCL_CONTINUE\fR) that was
+returned by the command evaluation. The callback function is expected,
+in turn, either to return a \fIresult\fR to control further evaluation.
+.PP
+Multiple \fBTcl_NRAddCallback\fR invocations may request multiple
+callbacks, which may be to the same or different callback
+functions. If multiple callbacks are requested, they are executed in
+last-in, first-out order, that is, the most recently requested
+callback is executed first.
+.SH EXAMPLE
+.PP
+The usual pattern for Tcl commands that invoke other Tcl commands
+is something like:
+.PP
+.CS
+int
+\fITheCmdObjProc\fR(
+    ClientData clientData,
+    Tcl_Interp *interp,
+    int objc,
+    Tcl_Obj *const objv[])
+{
+    int result;
+    Tcl_Obj *objPtr;
+
+    \fI... preparation ...\fR
+
+    result = \fBTcl_EvalObjEx\fR(interp, objPtr, 0);
+
+    \fI... postprocessing ...\fR
+
+    return result;
+}
+\fBTcl_CreateObjCommand\fR(interp, "theCommand",
+        \fITheCmdObjProc\fR, clientData, TheCmdDeleteProc);
+.CE
+.PP
+To enable a command like this one for trampoline-based evaluation,
+it must be split into three pieces:
+.IP \(bu
+A non-trampoline implementation, \fITheCmdNewObjProc\fR,
+which will simply create a trampoline
+and invoke the trampoline-based implementation.
+.IP \(bu
+A trampoline-enabled implementation, \fITheCmdNRObjProc\fR.  This
+function will perform the initialization, request that the trampoline
+call the postprocessing routine after command evaluation, and finally,
+request that the trampoline call the inner command.
+.IP \(bu
+A postprocessing routine, \fITheCmdPostProc\fR. This function will
+perform the postprocessing formerly done after the return from the
+inner command in \fITheCmdObjProc\fR.
+.PP
+The non-trampoline implementation is simple and stylized, containing
+a single statement:
+.PP
+.CS
+int
+\fITheCmdNewObjProc\fR(
+    ClientData clientData,
+    Tcl_Interp *interp,
+    int objc,
+    Tcl_Obj *const objv[])
+{
+    return \fBTcl_NRCallObjProc\fR(interp, name,
+            \fITheCmdNRObjProc\fR, clientData, objc, objv);
+}
+.CE
+.PP
+The trampoline-enabled implementation requests postprocessing,
+and returns to the trampoline requesting command evaluation.
+.PP
+.CS
+int
+\fITheCmdNRObjProc\fR
+    ClientData clientData,
+    Tcl_Interp *interp,
+    int objc,
+    Tcl_Obj *const objv[])
+{
+    Tcl_Obj *objPtr;
+
+    \fI... preparation ...\fR
+
+    \fBTcl_NRAddCallback\fR(interp, \fITheCmdPostProc\fR,
+            data0, data1, data2, data3);
+    /* \fIdata0 .. data3\fR are up to four one-word items to
+     * pass to the postprocessing procedure */
+
+    return \fBTcl_NREvalObj\fR(interp, objPtr, 0);
+}
+.CE
+.PP
+The postprocessing procedure does whatever the original command did
+upon return from the inner evaluation.
+.PP
+.CS
+int
+\fITheCmdNRPostProc\fR(
+    ClientData data[],
+    Tcl_Interp *interp,
+    int result)
+{
+    /* \fIdata[0] .. data[3]\fR are the four words of data
+     * passed to \fBTcl_NRAddCallback\fR */
+
+    \fI... postprocessing ...\fR
+
+    return result;
+}
+.CE
+.PP
+If \fItheCommand\fR is a command that results in multiple commands or
+scripts being evaluated, its postprocessing routine may schedule
+additional postprocessing and then request another command evaluation
+by means of \fBTcl_NREvalObj\fR or one of the other evaluation
+routines. Looping and sequencing constructs may be implemented in this way.
+.PP
+Finally, to install a trampoline-enabled command in the interpreter,
+\fBTcl_NRCreateCommand\fR is used in place of
+\fBTcl_CreateObjCommand\fR.  It accepts two command procedures instead
+of one. The first is for use when no trampoline is yet on the stack,
+and the second is for use when there is already a trampoline in place.
+.PP
+.CS
+\fBTcl_NRCreateCommand\fR(interp, "theCommand",
+        \fITheCmdObjProc\fR, \fITheCmdNRObjProc\fR, clientData,
+        TheCmdDeleteProc);

+.PP
+Namespaces are hierarchic naming contexts that can contain commands
+and variables.  They also maintain a list of patterns that describes
+what commands are exported, and can import commands that have been
+exported by other namespaces.  Namespaces can also be manipulated
+through the Tcl command \fBnamespace\fR.
+.PP
+The \fITcl_Namespace\fR structure encapsulates a namespace, and is
+guaranteed to have the following fields in it: \fIname\fR (the local
+name of the namespace, with no namespace separator characters in it,
+with empty denoting the global namespace), \fIfullName\fR (the fully
+specified name of the namespace), \fIclientData\fR, \fIdeleteProc\fR
+(the values specified in the call to \fBTcl_CreateNamespace\fR), and
+\fIparentPtr\fR (a pointer to the containing namespace, or NULL for
+the global namespace.)
+.PP
+\fBTcl_CreateNamespace\fR creates a new namespace.  The
+\fIdeleteProc\fR will have the following type signature:
+.PP
+.CS
+typedef void \fBTcl_NamespaceDeleteProc\fR(
+        ClientData \fIclientData\fR);
+.CE
+.PP
+\fBTcl_DeleteNamespace\fR deletes a namespace, calling the
+\fIdeleteProc\fR defined for the namespace (if any).
+.PP
+\fBTcl_AppendExportList\fR retrieves the export patterns for a
+namespace given namespace and appends them (as list items) to
+\fIobjPtr\fR.
+.PP
+\fBTcl_Export\fR sets and appends to the export patterns for a
+namespace.  Patterns are appended unless the \fIresetListFirst\fR flag
+is true.
+.PP
+\fBTcl_Import\fR imports commands matching a pattern into a
+namespace.  Note that the pattern must include the name of the
+namespace to import from.  This function returns an error if
+an attempt to import a command over an existing command is made,
+unless the \fIallowOverwrite\fR flag has been set.
+.PP
+\fBTcl_ForgetImport\fR removes imports matching a pattern.
+.PP
+\fBTcl_GetCurrentNamespace\fR returns the current namespace for an
+interpreter.
+.PP
+\fBTcl_GetGlobalNamespace\fR returns the global namespace for an
+interpreter.
+.PP
+\fBTcl_FindNamespace\fR searches for a namespace named \fIname\fR
+within the context of the namespace \fIcontextNsPtr\fR.  If the
+namespace cannot be found, NULL is returned.
+.PP
+\fBTcl_FindCommand\fR searches for a command named \fIname\fR within
+the context of the namespace \fIcontextNsPtr\fR.  If the command
+cannot be found, NULL is returned.
+.PP
+\fBTcl_GetNamespaceUnknownHandler\fR returns the unknown command handler
+for the namespace, or NULL if none is set.
+.PP
+\fBTcl_SetNamespaceUnknownHandler\fR sets the unknown command handler for

+.SH INTRODUCTION
+.PP
+The interfaces described here are used to customize the Tcl event
+loop.  The two most common customizations are to add new sources of
+events and to merge Tcl's event loop with some other event loop, such
+as one provided by an application in which Tcl is embedded.  Each of
+these tasks is described in a separate section below.
+.PP
+The procedures in this manual entry are the building blocks out of which
+the Tcl event notifier is constructed.  The event notifier is the lowest
+layer in the Tcl event mechanism.  It consists of three things:
+.IP [1]
+Event sources: these represent the ways in which events can be
+generated.  For example, there is a timer event source that implements
+the \fBTcl_CreateTimerHandler\fR procedure and the \fBafter\fR
+command, and there is a file event source that implements the
+\fBTcl_CreateFileHandler\fR procedure on Unix systems.  An event
+source must work with the notifier to detect events at the right
+times, record them on the event queue, and eventually notify
+higher-level software that they have occurred.  The procedures
+\fBTcl_CreateEventSource\fR, \fBTcl_DeleteEventSource\fR,
+and \fBTcl_SetMaxBlockTime\fR, \fBTcl_QueueEvent\fR, and
+\fBTcl_DeleteEvents\fR are used primarily by event sources.
+.IP [2]
+The event queue: for non-threaded applications,
+there is a single queue for the whole application,
+containing events that have been detected but not yet serviced.  Event
+sources place events onto the queue so that they may be processed in
+order at appropriate times during the event loop. The event queue
+guarantees a fair discipline of event handling, so that no event
+source can starve the others.  It also allows events to be saved for
+servicing at a future time.  Threaded applications work in a
+similar manner, except that there is a separate event queue for
+each thread containing a Tcl interpreter.
+\fBTcl_QueueEvent\fR is used (primarily
+by event sources) to add events to the event queue and 
+\fBTcl_DeleteEvents\fR is used to remove events from the queue without
+processing them.  In a threaded application, \fBTcl_QueueEvent\fR adds
+an event to the current thread's queue, and \fBTcl_ThreadQueueEvent\fR
+adds an event to a queue in a specific thread.
+.IP [3]
+The event loop: in order to detect and process events, the application
+enters a loop that waits for events to occur, places them on the event
+queue, and then processes them.  Most applications will do this by
+calling the procedure \fBTcl_DoOneEvent\fR, which is described in a
+separate manual entry.
+.PP
+Most Tcl applications need not worry about any of the internals of
+the Tcl notifier.  However, the notifier now has enough flexibility
+to be retargeted either for a new platform or to use an external event
+loop (such as the Motif event loop, when Tcl is embedded in a Motif
+application).  The procedures \fBTcl_WaitForEvent\fR and
+\fBTcl_SetTimer\fR are normally implemented by Tcl, but may be
+replaced with new versions to retarget the notifier (the
+\fBTcl_InitNotifier\fR, \fBTcl_AlertNotifier\fR,
+\fBTcl_FinalizeNotifier\fR, \fBTcl_Sleep\fR,
+\fBTcl_CreateFileHandler\fR, and \fBTcl_DeleteFileHandler\fR must
+also be replaced; see CREATING A NEW NOTIFIER below for details).
+The procedures \fBTcl_ServiceAll\fR, \fBTcl_ServiceEvent\fR,
+\fBTcl_GetServiceMode\fR, and \fBTcl_SetServiceMode\fR are provided
+to help connect Tcl's event loop to an external event loop such as
+Motif's.
+.SH "NOTIFIER BASICS"
+.PP
+The easiest way to understand how the notifier works is to consider
+what happens when \fBTcl_DoOneEvent\fR is called.
+\fBTcl_DoOneEvent\fR is passed a \fIflags\fR argument that indicates
+what sort of events it is OK to process and also whether or not to
+block if no events are ready.  \fBTcl_DoOneEvent\fR does the following
+things:
+.IP [1]
+Check the event queue to see if it contains any events that can
+be serviced.  If so, service the first possible event, remove it
+from the queue, and return.  It does this by calling
+\fBTcl_ServiceEvent\fR and passing in the \fIflags\fR argument.
+.IP [2]
+Prepare to block for an event.  To do this, \fBTcl_DoOneEvent\fR
+invokes a \fIsetup procedure\fR in each event source.
+The event source will perform event-source specific initialization and
+possibly call \fBTcl_SetMaxBlockTime\fR to limit how long
+\fBTcl_WaitForEvent\fR will block if no new events occur.
+.IP [3]
+Call \fBTcl_WaitForEvent\fR.  This procedure is implemented differently
+on different platforms;  it waits for an event to occur, based on the
+information provided by the event sources.
+It may cause the application to block if \fItimePtr\fR specifies
+an interval other than 0.
+\fBTcl_WaitForEvent\fR returns when something has happened,
+such as a file becoming readable or the interval given by \fItimePtr\fR
+expiring.  If there are no events for \fBTcl_WaitForEvent\fR to
+wait for, so that it would block forever, then it returns immediately
+and \fBTcl_DoOneEvent\fR returns 0.
+.IP [4]
+Call a \fIcheck procedure\fR in each event source.  The check
+procedure determines whether any events of interest to this source
+occurred.  If so, the events are added to the event queue.
+.IP [5]
+Check the event queue to see if it contains any events that can
+be serviced.  If so, service the first possible event, remove it
+from the queue, and return.
+.IP [6]
+See if there are idle callbacks pending. If so, invoke all of them and
+return.
+.IP [7]
+Either return 0 to indicate that no events were ready, or go back to
+step [2] if blocking was requested by the caller.
+.SH "CREATING A NEW EVENT SOURCE"
+.PP
+An event source consists of three procedures invoked by the notifier,
+plus additional C procedures that are invoked by higher-level code
+to arrange for event-driven callbacks.  The three procedures called
+by the notifier consist of the setup and check procedures described
+above, plus an additional procedure that is invoked when an event
+is removed from the event queue for servicing.
+.PP
+The procedure \fBTcl_CreateEventSource\fR creates a new event source.
+Its arguments specify the setup procedure and check procedure for
+the event source.
+\fISetupProc\fR should match the following prototype:
+.PP
+.CS
+typedef void \fBTcl_EventSetupProc\fR(
+        ClientData \fIclientData\fR,
+        int \fIflags\fR);
+.CE
+.PP
+The \fIclientData\fR argument will be the same as the \fIclientData\fR
+argument to \fBTcl_CreateEventSource\fR;  it is typically used to
+point to private information managed by the event source.
+The \fIflags\fR argument will be the same as the \fIflags\fR
+argument passed to \fBTcl_DoOneEvent\fR except that it will never
+be 0 (\fBTcl_DoOneEvent\fR replaces 0 with \fBTCL_ALL_EVENTS\fR).
+\fIFlags\fR indicates what kinds of events should be considered;
+if the bit corresponding to this event source is not set, the event
+source should return immediately without doing anything.  For
+example, the file event source checks for the \fBTCL_FILE_EVENTS\fR
+bit.
+.PP
+\fISetupProc\fR's job is to make sure that the application wakes up
+when events of the desired type occur.  This is typically done in a
+platform-dependent fashion.  For example, under Unix an event source
+might call \fBTcl_CreateFileHandler\fR; under Windows it might
+request notification with a Windows event.  For timer-driven event
+sources such as timer events or any polled event, the event source
+can call \fBTcl_SetMaxBlockTime\fR to force the application to wake
+up after a specified time even if no events have occurred.
+If no event source calls \fBTcl_SetMaxBlockTime\fR
+then \fBTcl_WaitForEvent\fR will wait as long as necessary for an
+event to occur; otherwise, it will only wait as long as the shortest
+interval passed to \fBTcl_SetMaxBlockTime\fR by one of the event
+sources.  If an event source knows that it already has events ready to
+report, it can request a zero maximum block time.  For example, the
+setup procedure for the X event source looks to see if there are
+events already queued.  If there are, it calls
+\fBTcl_SetMaxBlockTime\fR with a 0 block time so that
+\fBTcl_WaitForEvent\fR does not block if there is no new data on the X
+connection.
+The \fItimePtr\fR argument to \fBTcl_WaitForEvent\fR points to
+a structure that describes a time interval in seconds and
+microseconds:
+.PP
+.CS
+typedef struct Tcl_Time {
+    long \fIsec\fR;
+    long \fIusec\fR;
+} \fBTcl_Time\fR;
+.CE
+.PP
+The \fIusec\fR field should be less than 1000000.
+.PP
+Information provided to \fBTcl_SetMaxBlockTime\fR
+is only used for the next call to \fBTcl_WaitForEvent\fR; it is
+discarded after \fBTcl_WaitForEvent\fR returns.
+The next time an event wait is done each of the event sources'
+setup procedures will be called again, and they can specify new
+information for that event wait.
+.PP
+If the application uses an external event loop rather than
+\fBTcl_DoOneEvent\fR, the event sources may need to call
+\fBTcl_SetMaxBlockTime\fR at other times.  For example, if a new event
+handler is registered that needs to poll for events, the event source
+may call \fBTcl_SetMaxBlockTime\fR to set the block time to zero to
+force the external event loop to call Tcl.  In this case,
+\fBTcl_SetMaxBlockTime\fR invokes \fBTcl_SetTimer\fR with the shortest
+interval seen since the last call to \fBTcl_DoOneEvent\fR or
+\fBTcl_ServiceAll\fR.
+.PP
+In addition to the generic procedure \fBTcl_SetMaxBlockTime\fR, other
+platform-specific procedures may also be available for
+\fIsetupProc\fR, if there is additional information needed by
+\fBTcl_WaitForEvent\fR on that platform.  For example, on Unix systems
+the \fBTcl_CreateFileHandler\fR interface can be used to wait for file events.
+.PP
+The second procedure provided by each event source is its check
+procedure, indicated by the \fIcheckProc\fR argument to
+\fBTcl_CreateEventSource\fR.  \fICheckProc\fR must match the
+following prototype:
+.PP
+.CS
+typedef void \fBTcl_EventCheckProc\fR(
+        ClientData \fIclientData\fR,
+        int \fIflags\fR);
+.CE
+.PP
+The arguments to this procedure are the same as those for \fIsetupProc\fR.
+\fBCheckProc\fR is invoked by \fBTcl_DoOneEvent\fR after it has waited
+for events.  Presumably at least one event source is now prepared to
+queue an event.  \fBTcl_DoOneEvent\fR calls each of the event sources
+in turn, so they all have a chance to queue any events that are ready.
+The check procedure does two things.  First, it must see if any events
+have triggered.  Different event sources do this in different ways.
+.PP
+If an event source's check procedure detects an interesting event, it
+must add the event to Tcl's event queue.  To do this, the event source
+calls \fBTcl_QueueEvent\fR.  The \fIevPtr\fR argument is a pointer to
+a dynamically allocated structure containing the event (see below for
+more information on memory management issues).  Each event source can
+define its own event structure with whatever information is relevant
+to that event source.  However, the first element of the structure
+must be a structure of type \fBTcl_Event\fR, and the address of this
+structure is used when communicating between the event source and the
+rest of the notifier.  A \fBTcl_Event\fR has the following definition:
+.PP
+.CS
+typedef struct {
+    Tcl_EventProc *\fIproc\fR;
+    struct Tcl_Event *\fInextPtr\fR;
+} \fBTcl_Event\fR;
+.CE
+.PP
+The event source must fill in the \fIproc\fR field of
+the event before calling \fBTcl_QueueEvent\fR.
+The \fInextPtr\fR is used to link together the events in the queue
+and should not be modified by the event source.
+.PP
+An event may be added to the queue at any of three positions, depending
+on the \fIposition\fR argument to \fBTcl_QueueEvent\fR:
+.IP \fBTCL_QUEUE_TAIL\fR 24
+Add the event at the back of the queue, so that all other pending
+events will be serviced first.  This is almost always the right
+place for new events.
+.IP \fBTCL_QUEUE_HEAD\fR 24
+Add the event at the front of the queue, so that it will be serviced
+before all other queued events.
+.IP \fBTCL_QUEUE_MARK\fR 24
+Add the event at the front of the queue, unless there are other
+events at the front whose position is \fBTCL_QUEUE_MARK\fR;  if so,
+add the new event just after all other \fBTCL_QUEUE_MARK\fR events.
+This value of \fIposition\fR is used to insert an ordered sequence of
+events at the front of the queue, such as a series of
+Enter and Leave events synthesized during a grab or ungrab operation
+in Tk.
+.PP
+When it is time to handle an event from the queue (steps 1 and 4
+above) \fBTcl_ServiceEvent\fR will invoke the \fIproc\fR specified
+in the first queued \fBTcl_Event\fR structure.
+\fIProc\fR must match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_EventProc\fR(
+        Tcl_Event *\fIevPtr\fR,
+        int \fIflags\fR);
+.CE
+.PP
+The first argument to \fIproc\fR is a pointer to the event, which will
+be the same as the first argument to the \fBTcl_QueueEvent\fR call that
+added the event to the queue.
+The second argument to \fIproc\fR is the \fIflags\fR argument for the
+current call to \fBTcl_ServiceEvent\fR;  this is used by the event source
+to return immediately if its events are not relevant.
+.PP
+It is up to \fIproc\fR to handle the event, typically by invoking
+one or more Tcl commands or C-level callbacks.
+Once the event source has finished handling the event it returns 1
+to indicate that the event can be removed from the queue.
+If for some reason the event source decides that the event cannot
+be handled at this time, it may return 0 to indicate that the event
+should be deferred for processing later;  in this case \fBTcl_ServiceEvent\fR
+will go on to the next event in the queue and attempt to service it.
+There are several reasons why an event source might defer an event.
+One possibility is that events of this type are excluded by the
+\fIflags\fR argument.
+For example, the file event source will always return 0 if the
+\fBTCL_FILE_EVENTS\fR bit is not set in \fIflags\fR.
+Another example of deferring events happens in Tk if
+\fBTk_RestrictEvents\fR has been invoked to defer certain kinds
+of window events.
+.PP
+When \fIproc\fR returns 1, \fBTcl_ServiceEvent\fR will remove the
+event from the event queue and free its storage.
+Note that the storage for an event must be allocated by
+the event source (using \fBTcl_Alloc\fR or the Tcl macro \fBckalloc\fR)
+before calling \fBTcl_QueueEvent\fR, but it
+will be freed by \fBTcl_ServiceEvent\fR, not by the event source.
+.PP
+Threaded applications work in a
+similar manner, except that there is a separate event queue for
+each thread containing a Tcl interpreter.
+Calling \fBTcl_QueueEvent\fR in a multithreaded application adds
+an event to the current thread's queue.
+To add an event to another thread's queue, use \fBTcl_ThreadQueueEvent\fR.
+\fBTcl_ThreadQueueEvent\fR accepts as an argument a Tcl_ThreadId argument,
+which uniquely identifies a thread in a Tcl application.  To obtain the
+Tcl_ThreadId for the current thread, use the \fBTcl_GetCurrentThread\fR
+procedure.  (A thread would then need to pass this identifier to other
+threads for those threads to be able to add events to its queue.)
+After adding an event to another thread's queue, you then typically
+need to call \fBTcl_ThreadAlert\fR to
+.QW "wake up"
+that thread's notifier to alert it to the new event.
+.PP
+\fBTcl_DeleteEvents\fR can be used to explicitly remove one or more
+events from the event queue.  \fBTcl_DeleteEvents\fR calls \fIproc\fR
+for each event in the queue, deleting those for with the procedure
+returns 1.  Events for which the procedure returns 0 are left in the
+queue.  \fIProc\fR should match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_EventDeleteProc\fR(
+        Tcl_Event *\fIevPtr\fR,
+        ClientData \fIclientData\fR);
+.CE
+.PP
+The \fIclientData\fR argument will be the same as the \fIclientData\fR
+argument to \fBTcl_DeleteEvents\fR; it is typically used to point to
+private information managed by the event source.  The \fIevPtr\fR will
+point to the next event in the queue.
+.PP
+\fBTcl_DeleteEventSource\fR deletes an event source.  The \fIsetupProc\fR,
+\fIcheckProc\fR, and \fIclientData\fR arguments must exactly match those
+provided to the \fBTcl_CreateEventSource\fR for the event source to be deleted.
+If no such source exists, \fBTcl_DeleteEventSource\fR has no effect.
+.SH "CREATING A NEW NOTIFIER"
+.PP
+The notifier consists of all the procedures described in this manual
+entry, plus \fBTcl_DoOneEvent\fR and \fBTcl_Sleep\fR, which are
+available on all platforms, and \fBTcl_CreateFileHandler\fR and
+\fBTcl_DeleteFileHandler\fR, which are Unix-specific.  Most of these
+procedures are generic, in that they are the same for all notifiers.
+However, none of the procedures are notifier-dependent:
+\fBTcl_InitNotifier\fR, \fBTcl_AlertNotifier\fR,
+\fBTcl_FinalizeNotifier\fR, \fBTcl_SetTimer\fR, \fBTcl_Sleep\fR,
+\fBTcl_WaitForEvent\fR, \fBTcl_CreateFileHandler\fR,
+\fBTcl_DeleteFileHandler\fR and \fBTcl_ServiceModeHook\fR.  To support a
+new platform or to integrate Tcl with an application-specific event loop,
+you must write new versions of these procedures.
+.PP
+\fBTcl_InitNotifier\fR initializes the notifier state and returns
+a handle to the notifier state.  Tcl calls this
+procedure when initializing a Tcl interpreter.  Similarly,
+\fBTcl_FinalizeNotifier\fR shuts down the notifier, and is
+called by \fBTcl_Finalize\fR when shutting down a Tcl interpreter.
+.PP
+\fBTcl_WaitForEvent\fR is the lowest-level procedure in the notifier;
+it is responsible for waiting for an
+.QW interesting
+event to occur or
+for a given time to elapse.  Before \fBTcl_WaitForEvent\fR is invoked,
+each of the event sources' setup procedure will have been invoked.
+The \fItimePtr\fR argument to
+\fBTcl_WaitForEvent\fR gives the maximum time to block for an event,
+based on calls to \fBTcl_SetMaxBlockTime\fR made by setup procedures
+and on other information (such as the \fBTCL_DONT_WAIT\fR bit in
+\fIflags\fR).
+.PP
+Ideally, \fBTcl_WaitForEvent\fR should only wait for an event
+to occur; it should not actually process the event in any way.
+Later on, the
+event sources will process the raw events and create Tcl_Events on
+the event queue in their \fIcheckProc\fR procedures.
+However, on some platforms (such as Windows) this is not possible;
+events may be processed in \fBTcl_WaitForEvent\fR, including queuing
+Tcl_Events and more (for example, callbacks for native widgets may be
+invoked).  The return value from \fBTcl_WaitForEvent\fR must be either
+0, 1, or \-1.  On platforms such as Windows where events get processed in
+\fBTcl_WaitForEvent\fR, a return value of 1 means that there may be more
+events still pending that have not been processed.  This is a sign to the
+caller that it must call \fBTcl_WaitForEvent\fR again if it wants all
+pending events to be processed. A 0 return value means that calling
+\fBTcl_WaitForEvent\fR again will not have any effect: either this is a
+platform where \fBTcl_WaitForEvent\fR only waits without doing any event
+processing, or \fBTcl_WaitForEvent\fR knows for sure that there are no
+additional events to process (e.g. it returned because the time
+elapsed).  Finally, a return value of \-1 means that the event loop is
+no longer operational and the application should probably unwind and
+terminate.  Under Windows this happens when a WM_QUIT message is received;
+under Unix it happens when \fBTcl_WaitForEvent\fR would have waited
+forever because there were no active event sources and the timeout was
+infinite.
+.PP
+\fBTcl_AlertNotifier\fR is used in multithreaded applications to allow
+any thread to
+.QW "wake up"
+the notifier to alert it to new events on its
+queue.  \fBTcl_AlertNotifier\fR requires as an argument the notifier
+handle returned by \fBTcl_InitNotifier\fR.
+.PP
+If the notifier will be used with an external event loop, then it must
+also support the \fBTcl_SetTimer\fR interface.  \fBTcl_SetTimer\fR is
+invoked by \fBTcl_SetMaxBlockTime\fR whenever the maximum blocking
+time has been reduced.  \fBTcl_SetTimer\fR should arrange for the
+external event loop to invoke \fBTcl_ServiceAll\fR after the specified
+interval even if no events have occurred.  This interface is needed
+because \fBTcl_WaitForEvent\fR is not invoked when there is an external
+event loop.  If the
+notifier will only be used from \fBTcl_DoOneEvent\fR, then
+\fBTcl_SetTimer\fR need not do anything.
+.PP
+\fBTcl_ServiceModeHook\fR is called by the platform-independent portion
+of the notifier when client code makes a call to
+\fBTcl_SetServiceMode\fR. This hook is provided to support operating
+systems that require special event handling when the application is in
+a modal loop (the Windows notifier, for instance, uses this hook to
+create a communication window).
+.PP
+On Unix systems, the file event source also needs support from the
+notifier.  The file event source consists of the
+\fBTcl_CreateFileHandler\fR and \fBTcl_DeleteFileHandler\fR
+procedures, which are described in the \fBTcl_CreateFileHandler\fR
+manual page.
+.PP
+The \fBTcl_Sleep\fR and \fBTcl_DoOneEvent\fR interfaces are described
+in their respective manual pages.
+.PP
+The easiest way to create a new notifier is to look at the code
+for an existing notifier, such as the files \fBunix/tclUnixNotfy.c\fR
+or \fBwin/tclWinNotify.c\fR in the Tcl source distribution.
+.SH "REPLACING THE NOTIFIER"
+.PP
+A notifier that has been written according to the conventions above
+can also be installed in a running process in place of the standard
+notifier.  This mechanism is used so that a single executable can be
+used (with the standard notifier) as a stand-alone program and reused
+(with a replacement notifier in a loadable extension) as an extension
+to another program, such as a Web browser plugin.
+.PP
+To do this, the extension makes a call to \fBTcl_SetNotifier\fR
+passing a pointer to a \fBTcl_NotifierProcs\fR data structure.  The
+structure has the following layout:
+.PP
+.CS
+typedef struct Tcl_NotifierProcs {
+    Tcl_SetTimerProc *\fIsetTimerProc\fR;
+    Tcl_WaitForEventProc *\fIwaitForEventProc\fR;
+    Tcl_CreateFileHandlerProc *\fIcreateFileHandlerProc\fR;
+    Tcl_DeleteFileHandlerProc *\fIdeleteFileHandlerProc\fR;
+    Tcl_InitNotifierProc *\fIinitNotifierProc\fR;
+    Tcl_FinalizeNotifierProc *\fIfinalizeNotifierProc\fR;
+    Tcl_AlertNotifierProc *\fIalertNotifierProc\fR;
+    Tcl_ServiceModeHookProc *\fIserviceModeHookProc\fR;
+} \fBTcl_NotifierProcs\fR;
+.CE
+.PP
+Following the call to \fBTcl_SetNotifier\fR, the pointers given in
+the \fBTcl_NotifierProcs\fR structure replace whatever notifier had
+been installed in the process.
+.PP
+It is extraordinarily unwise to replace a running notifier. Normally,
+\fBTcl_SetNotifier\fR should be called at process initialization time
+before the first call to \fBTcl_InitNotifier\fR.
+.SH "EXTERNAL EVENT LOOPS"
+.PP
+The notifier interfaces are designed so that Tcl can be embedded into
+applications that have their own private event loops.  In this case,
+the application does not call \fBTcl_DoOneEvent\fR except in the case
+of recursive event loops such as calls to the Tcl commands \fBupdate\fR
+or \fBvwait\fR.  Most of the time is spent in the external event loop
+of the application.  In this case the notifier must arrange for the
+external event loop to call back into Tcl when something
+happens on the various Tcl event sources.  These callbacks should
+arrange for appropriate Tcl events to be placed on the Tcl event queue.
+.PP
+Because the external event loop is not calling \fBTcl_DoOneEvent\fR on
+a regular basis, it is up to the notifier to arrange for
+\fBTcl_ServiceEvent\fR to be called whenever events are pending on the
+Tcl event queue.  The easiest way to do this is to invoke
+\fBTcl_ServiceAll\fR at the end of each callback from the external
+event loop.  This will ensure that all of the event sources are
+polled, any queued events are serviced, and any pending idle handlers
+are processed before returning control to the application.  In
+addition, event sources that need to poll for events can call
+\fBTcl_SetMaxBlockTime\fR to force the external event loop to call
+Tcl even if no events are available on the system event queue.
+.PP
+As a side effect of processing events detected in the main external
+event loop, Tcl may invoke \fBTcl_DoOneEvent\fR to start a recursive event
+loop in commands like \fBvwait\fR.  \fBTcl_DoOneEvent\fR will invoke
+the external event loop, which will result in callbacks as described
+in the preceding paragraph, which will result in calls to
+\fBTcl_ServiceAll\fR.  However, in these cases it is undesirable to
+service events in \fBTcl_ServiceAll\fR.  Servicing events there is
+unnecessary because control will immediately return to the
+external event loop and hence to \fBTcl_DoOneEvent\fR, which can
+service the events itself.  Furthermore, \fBTcl_DoOneEvent\fR is
+supposed to service only a single event, whereas \fBTcl_ServiceAll\fR
+normally services all pending events.  To handle this situation,
+\fBTcl_DoOneEvent\fR sets a flag for \fBTcl_ServiceAll\fR
+that causes it to return without servicing any events.
+This flag is called the \fIservice mode\fR;
+\fBTcl_DoOneEvent\fR restores it to its previous value before it returns.
+.PP
+In some cases, however, it may be necessary for \fBTcl_ServiceAll\fR
+to service events
+even when it has been invoked from \fBTcl_DoOneEvent\fR.  This happens
+when there is yet another recursive event loop invoked via an
+event handler called by \fBTcl_DoOneEvent\fR (such as one that is
+part of a native widget).  In this case, \fBTcl_DoOneEvent\fR may not
+have a chance to service events so \fBTcl_ServiceAll\fR must service
+them all.  Any recursive event loop that calls an external event
+loop rather than \fBTcl_DoOneEvent\fR must reset the service mode so
+that all events get processed in \fBTcl_ServiceAll\fR.  This is done
+by invoking the \fBTcl_SetServiceMode\fR procedure.  If
+\fBTcl_SetServiceMode\fR is passed \fBTCL_SERVICE_NONE\fR, then calls
+to \fBTcl_ServiceAll\fR will return immediately without processing any
+events.  If \fBTcl_SetServiceMode\fR is passed \fBTCL_SERVICE_ALL\fR,
+then calls to \fBTcl_ServiceAll\fR will behave normally.
+\fBTcl_SetServiceMode\fR returns the previous value of the service
+mode, which should be restored when the recursive loop exits.
+\fBTcl_GetServiceMode\fR returns the current value of the service
+mode.

+.SH INTRODUCTION
+.PP
+This man page presents an overview of Tcl values (called \fBTcl_Obj\fRs for
+historical reasons) and how they are used.
+It also describes generic procedures for managing Tcl values.
+These procedures are used to create and copy values,
+and increment and decrement the count of references (pointers) to values.
+The procedures are used in conjunction with ones
+that operate on specific types of values such as
+\fBTcl_GetIntFromObj\fR and \fBTcl_ListObjAppendElement\fR.
+The individual procedures are described along with the data structures
+they manipulate.
+.PP
+Tcl's \fIdual-ported\fR values provide a general-purpose mechanism
+for storing and exchanging Tcl values.
+They largely replace the use of strings in Tcl.
+For example, they are used to store variable values,
+command arguments, command results, and scripts.
+Tcl values behave like strings but also hold an internal representation
+that can be manipulated more efficiently.
+For example, a Tcl list is now represented as a value
+that holds the list's string representation
+as well as an array of pointers to the values for each list element.
+Dual-ported values avoid most runtime type conversions.
+They also improve the speed of many operations
+since an appropriate representation is immediately available.
+The compiler itself uses Tcl values to
+cache the instruction bytecodes resulting from compiling scripts.
+.PP
+The two representations are a cache of each other and are computed lazily.
+That is, each representation is only computed when necessary,
+it is computed from the other representation,
+and, once computed, it is saved.
+In addition, a change in one representation invalidates the other one.
+As an example, a Tcl program doing integer calculations can
+operate directly on a variable's internal machine integer
+representation without having to constantly convert
+between integers and strings.
+Only when it needs a string representing the variable's value,
+say to print it,
+will the program regenerate the string representation from the integer.
+Although values contain an internal representation,
+their semantics are defined in terms of strings:
+an up-to-date string can always be obtained,
+and any change to the value will be reflected in that string
+when the value's string representation is fetched.
+Because of this representation invalidation and regeneration,
+it is dangerous for extension writers to access
+\fBTcl_Obj\fR fields directly.
+It is better to access Tcl_Obj information using
+procedures like \fBTcl_GetStringFromObj\fR and \fBTcl_GetString\fR.
+.PP
+Values are allocated on the heap
+and are referenced using a pointer to their \fBTcl_Obj\fR structure.
+Values are shared as much as possible.
+This significantly reduces storage requirements
+because some values such as long lists are very large.
+Also, most Tcl values are only read and never modified.
+This is especially true for procedure arguments,
+which can be shared between the caller and the called procedure.
+Assignment and argument binding is done by
+simply assigning a pointer to the value. 
+Reference counting is used to determine when it is safe to
+reclaim a value's storage.
+.PP
+Tcl values are typed.
+A value's internal representation is controlled by its type.
+Several types are predefined in the Tcl core
+including integer, double, list, and bytecode.
+Extension writers can extend the set of types
+by defining their own \fBTcl_ObjType\fR structs.
+.SH "THE TCL_OBJ STRUCTURE"
+.PP
+Each Tcl value is represented by a \fBTcl_Obj\fR structure
+which is defined as follows.
+.PP
+.CS
+typedef struct Tcl_Obj {
+    int \fIrefCount\fR;
+    char *\fIbytes\fR;
+    int \fIlength\fR;
+    const Tcl_ObjType *\fItypePtr\fR;
+    union {
+        long \fIlongValue\fR;
+        double \fIdoubleValue\fR;
+        void *\fIotherValuePtr\fR;
+        Tcl_WideInt \fIwideValue\fR;
+        struct {
+            void *\fIptr1\fR;
+            void *\fIptr2\fR;
+        } \fItwoPtrValue\fR;
+        struct {
+            void *\fIptr\fR;
+            unsigned long \fIvalue\fR;
+        } \fIptrAndLongRep\fR;
+    } \fIinternalRep\fR;
+} \fBTcl_Obj\fR;
+.CE
+.PP
+The \fIbytes\fR and the \fIlength\fR members together hold
+a value's UTF-8 string representation,
+which is a \fIcounted string\fR not containing null bytes (UTF-8 null
+characters should be encoded as a two byte sequence: 192, 128.)
+\fIbytes\fR points to the first byte of the string representation.
+The \fIlength\fR member gives the number of bytes.
+The byte array must always have a null byte after the last data byte,
+at offset \fIlength\fR;
+this allows string representations
+to be treated as conventional null-terminated C strings.
+C programs use \fBTcl_GetStringFromObj\fR and \fBTcl_GetString\fR to get
+a value's string representation.
+If \fIbytes\fR is NULL,
+the string representation is invalid.
+.PP
+A value's type manages its internal representation.
+The member \fItypePtr\fR points to the Tcl_ObjType structure
+that describes the type.
+If \fItypePtr\fR is NULL,
+the internal representation is invalid.
+.PP
+The \fIinternalRep\fR union member holds
+a value's internal representation.
+This is either a (long) integer, a double-precision floating-point number,
+a pointer to a value containing additional information
+needed by the value's type to represent the value, a Tcl_WideInt
+integer, two arbitrary pointers, or a pair made up of an unsigned long
+integer and a pointer.
+.PP
+The \fIrefCount\fR member is used to tell when it is safe to free
+a value's storage.
+It holds the count of active references to the value.
+Maintaining the correct reference count is a key responsibility
+of extension writers.
+Reference counting is discussed below
+in the section \fBSTORAGE MANAGEMENT OF VALUES\fR.
+.PP
+Although extension writers can directly access
+the members of a Tcl_Obj structure,
+it is much better to use the appropriate procedures and macros.
+For example, extension writers should never
+read or update \fIrefCount\fR directly;
+they should use macros such as
+\fBTcl_IncrRefCount\fR and \fBTcl_IsShared\fR instead.
+.PP
+A key property of Tcl values is that they hold two representations.
+A value typically starts out containing only a string representation:
+it is untyped and has a NULL \fItypePtr\fR.
+A value containing an empty string or a copy of a specified string
+is created using \fBTcl_NewObj\fR or \fBTcl_NewStringObj\fR respectively.
+A value's string value is gotten with
+\fBTcl_GetStringFromObj\fR or \fBTcl_GetString\fR
+and changed with \fBTcl_SetStringObj\fR.
+If the value is later passed to a procedure like \fBTcl_GetIntFromObj\fR
+that requires a specific internal representation,
+the procedure will create one and set the value's \fItypePtr\fR.
+The internal representation is computed from the string representation.
+A value's two representations are duals of each other:
+changes made to one are reflected in the other.
+For example, \fBTcl_ListObjReplace\fR will modify a value's
+internal representation and the next call to \fBTcl_GetStringFromObj\fR
+or \fBTcl_GetString\fR will reflect that change.
+.PP
+Representations are recomputed lazily for efficiency.
+A change to one representation made by a procedure
+such as \fBTcl_ListObjReplace\fR is not reflected immediately
+in the other representation.
+Instead, the other representation is marked invalid
+so that it is only regenerated if it is needed later.
+Most C programmers never have to be concerned with how this is done
+and simply use procedures such as \fBTcl_GetBooleanFromObj\fR or
+\fBTcl_ListObjIndex\fR.
+Programmers that implement their own value types
+must check for invalid representations
+and mark representations invalid when necessary.
+The procedure \fBTcl_InvalidateStringRep\fR is used
+to mark a value's string representation invalid and to
+free any storage associated with the old string representation.
+.PP
+Values usually remain one type over their life,
+but occasionally a value must be converted from one type to another.
+For example, a C program might build up a string in a value
+with repeated calls to \fBTcl_AppendToObj\fR,
+and then call \fBTcl_ListObjIndex\fR to extract a list element from
+the value.
+The same value holding the same string value
+can have several different internal representations
+at different times.
+Extension writers can also force a value to be converted from one type
+to another using the \fBTcl_ConvertToType\fR procedure.
+Only programmers that create new value types need to be concerned
+about how this is done.
+A procedure defined as part of the value type's implementation
+creates a new internal representation for a value
+and changes its \fItypePtr\fR.
+See the man page for \fBTcl_RegisterObjType\fR
+to see how to create a new value type.
+.SH "EXAMPLE OF THE LIFETIME OF A VALUE"
+.PP
+As an example of the lifetime of a value,
+consider the following sequence of commands:
+.PP
+.CS
+\fBset x 123\fR
+.CE
+.PP
+This assigns to \fIx\fR an untyped value whose
+\fIbytes\fR member points to \fB123\fR and \fIlength\fR member contains 3.
+The value's \fItypePtr\fR member is NULL.
+.PP
+.CS
+\fBputs "x is $x"\fR
+.CE
+.PP
+\fIx\fR's string representation is valid (since \fIbytes\fR is non-NULL)
+and is fetched for the command.
+.PP
+.CS
+\fBincr x\fR
+.CE
+.PP
+The \fBincr\fR command first gets an integer from \fIx\fR's value
+by calling \fBTcl_GetIntFromObj\fR.
+This procedure checks whether the value is already an integer value.
+Since it is not, it converts the value
+by setting the value's \fIinternalRep.longValue\fR member
+to the integer \fB123\fR
+and setting the value's \fItypePtr\fR
+to point to the integer Tcl_ObjType structure.
+Both representations are now valid.
+\fBincr\fR increments the value's integer internal representation
+then invalidates its string representation
+(by calling \fBTcl_InvalidateStringRep\fR)
+since the string representation
+no longer corresponds to the internal representation.
+.PP
+.CS
+\fBputs "x is now $x"\fR
+.CE
+.PP
+The string representation of \fIx\fR's value is needed
+and is recomputed.
+The string representation is now \fB124\fR
+and both representations are again valid.
+.SH "STORAGE MANAGEMENT OF VALUES"
+.PP
+Tcl values are allocated on the heap and are shared as much as possible
+to reduce storage requirements.
+Reference counting is used to determine when a value is
+no longer needed and can safely be freed.
+A value just created by \fBTcl_NewObj\fR or \fBTcl_NewStringObj\fR
+has \fIrefCount\fR 0.
+The macro \fBTcl_IncrRefCount\fR increments the reference count
+when a new reference to the value is created.
+The macro \fBTcl_DecrRefCount\fR decrements the count
+when a reference is no longer needed and,
+if the value's reference count drops to zero, frees its storage.
+A value shared by different code or data structures has
+\fIrefCount\fR greater than 1.
+Incrementing a value's reference count ensures that
+it will not be freed too early or have its value change accidentally.
+.PP
+As an example, the bytecode interpreter shares argument values
+between calling and called Tcl procedures to avoid having to copy values.
+It assigns the call's argument values to the procedure's
+formal parameter variables.
+In doing so, it calls \fBTcl_IncrRefCount\fR to increment
+the reference count of each argument since there is now a new
+reference to it from the formal parameter.
+When the called procedure returns,
+the interpreter calls \fBTcl_DecrRefCount\fR to decrement
+each argument's reference count.
+When a value's reference count drops less than or equal to zero,
+\fBTcl_DecrRefCount\fR reclaims its storage.
+Most command procedures do not have to be concerned about
+reference counting since they use a value's value immediately
+and do not retain a pointer to the value after they return.
+However, if they do retain a pointer to a value in a data structure,
+they must be careful to increment its reference count
+since the retained pointer is a new reference.
+.PP
+Command procedures that directly modify values
+such as those for \fBlappend\fR and \fBlinsert\fR must be careful to
+copy a shared value before changing it.
+They must first check whether the value is shared
+by calling \fBTcl_IsShared\fR.
+If the value is shared they must copy the value
+by using \fBTcl_DuplicateObj\fR;
+this returns a new duplicate of the original value
+that has \fIrefCount\fR 0.
+If the value is not shared,
+the command procedure
+.QW "owns"
+the value and can safely modify it directly.
+For example, the following code appears in the command procedure
+that implements \fBlinsert\fR.
+This procedure modifies the list value passed to it in \fIobjv[1]\fR
+by inserting \fIobjc-3\fR new elements before \fIindex\fR.
+.PP
+.CS
+listPtr = objv[1];
+if (\fBTcl_IsShared\fR(listPtr)) {
+    listPtr = \fBTcl_DuplicateObj\fR(listPtr);
+}
+result = Tcl_ListObjReplace(interp, listPtr, index, 0,
+        (objc-3), &(objv[3]));
+.CE
+.PP
+As another example, \fBincr\fR's command procedure
+must check whether the variable's value is shared before
+incrementing the integer in its internal representation.
+If it is shared, it needs to duplicate the value
+in order to avoid accidentally changing values in other data structures.

+.BE
+
+.SH DESCRIPTION
+.PP
+The procedures in this man page manage Tcl value types (sometimes
+referred to as object types or \fBTcl_ObjType\fRs for historical reasons).
+They are used to register new value types, look up types,
+and force conversions from one type to another.
+.PP
+\fBTcl_RegisterObjType\fR registers a new Tcl value type
+in the table of all value types that \fBTcl_GetObjType\fR
+can look up by name.  There are other value types supported by Tcl
+as well, which Tcl chooses not to register.  Extensions can likewise
+choose to register the value types they create or not.
+The argument \fItypePtr\fR points to a Tcl_ObjType structure that
+describes the new type by giving its name
+and by supplying pointers to four procedures
+that implement the type.
+If the type table already contains a type
+with the same name as in \fItypePtr\fR,
+it is replaced with the new type.
+The Tcl_ObjType structure is described
+in the section \fBTHE TCL_OBJTYPE STRUCTURE\fR below.
+.PP
+\fBTcl_GetObjType\fR returns a pointer to the registered Tcl_ObjType
+with name \fItypeName\fR.
+It returns NULL if no type with that name is registered.
+.PP
+\fBTcl_AppendAllObjTypes\fR appends the name of each registered value type
+as a list element onto the Tcl value referenced by \fIobjPtr\fR.
+The return value is \fBTCL_OK\fR unless there was an error
+converting \fIobjPtr\fR to a list value;
+in that case \fBTCL_ERROR\fR is returned.
+.PP
+\fBTcl_ConvertToType\fR converts a value from one type to another
+if possible.
+It creates a new internal representation for \fIobjPtr\fR
+appropriate for the target type \fItypePtr\fR
+and sets its \fItypePtr\fR member as determined by calling the 
+\fItypePtr->setFromAnyProc\fR routine.  
+Any internal representation for \fIobjPtr\fR's old type is freed.
+If an error occurs during conversion, it returns \fBTCL_ERROR\fR
+and leaves an error message in the result value for \fIinterp\fR
+unless \fIinterp\fR is NULL.
+Otherwise, it returns \fBTCL_OK\fR.
+Passing a NULL \fIinterp\fR allows this procedure to be used
+as a test whether the conversion can be done (and in fact was done).
+.VS 8.5
+.PP
+In many cases, the \fItypePtr->setFromAnyProc\fR routine will
+set \fIobjPtr->typePtr\fR to the argument value \fItypePtr\fR,
+but that is no longer guaranteed.  The \fIsetFromAnyProc\fR is
+free to set the internal representation for \fIobjPtr\fR to make
+use of another related Tcl_ObjType, if it sees fit.
+.VE 8.5
+.SH "THE TCL_OBJTYPE STRUCTURE"
+.PP
+Extension writers can define new value types by defining four
+procedures and
+initializing a Tcl_ObjType structure to describe the type.
+Extension writers may also pass a pointer to their Tcl_ObjType
+structure to \fBTcl_RegisterObjType\fR if they wish to permit
+other extensions to look up their Tcl_ObjType by name with
+the \fBTcl_GetObjType\fR routine.
+The \fBTcl_ObjType\fR structure is defined as follows:
+.PP
+.CS
+typedef struct Tcl_ObjType {
+    const char *\fIname\fR;
+    Tcl_FreeInternalRepProc *\fIfreeIntRepProc\fR;
+    Tcl_DupInternalRepProc *\fIdupIntRepProc\fR;
+    Tcl_UpdateStringProc *\fIupdateStringProc\fR;
+    Tcl_SetFromAnyProc *\fIsetFromAnyProc\fR;
+} \fBTcl_ObjType\fR;
+.CE
+.SS "THE NAME FIELD"
+.PP
+The \fIname\fR member describes the name of the type, e.g. \fBint\fR.
+When a type is registered, this is the name used by callers
+of \fBTcl_GetObjType\fR to lookup the type.  For unregistered
+types, the \fIname\fR field is primarily of value for debugging.
+The remaining four members are pointers to procedures
+called by the generic Tcl value code:
+.SS "THE SETFROMANYPROC FIELD"
+.PP
+The \fIsetFromAnyProc\fR member contains the address of a function
+called to create a valid internal representation
+from a value's string representation.
+.PP
+.CS
+typedef int \fBTcl_SetFromAnyProc\fR(
+        Tcl_Interp *\fIinterp\fR,
+        Tcl_Obj *\fIobjPtr\fR);
+.CE
+.PP
+If an internal representation cannot be created from the string,
+it returns \fBTCL_ERROR\fR and puts a message
+describing the error in the result value for \fIinterp\fR
+unless \fIinterp\fR is NULL.
+If \fIsetFromAnyProc\fR is successful,
+it stores the new internal representation,
+sets \fIobjPtr\fR's \fItypePtr\fR member to point to
+the \fBTcl_ObjType\fR struct corresponding to the new
+internal representation, and returns \fBTCL_OK\fR.
+Before setting the new internal representation,
+the \fIsetFromAnyProc\fR must free any internal representation
+of \fIobjPtr\fR's old type;
+it does this by calling the old type's \fIfreeIntRepProc\fR
+if it is not NULL.
+.PP
+As an example, the \fIsetFromAnyProc\fR for the built-in Tcl list type
+gets an up-to-date string representation for \fIobjPtr\fR
+by calling \fBTcl_GetStringFromObj\fR.
+It parses the string to verify it is in a valid list format and
+to obtain each element value in the list, and, if this succeeds,
+stores the list elements in \fIobjPtr\fR's internal representation
+and sets \fIobjPtr\fR's \fItypePtr\fR member to point to the list type's
+Tcl_ObjType structure.
+.PP
+Do not release \fIobjPtr\fR's old internal representation unless you
+replace it with a new one or reset the \fItypePtr\fR member to NULL.
+.PP
+The \fIsetFromAnyProc\fR member may be set to NULL, if the routines
+making use of the internal representation have no need to derive that
+internal representation from an arbitrary string value.  However, in
+this case, passing a pointer to the type to \fBTcl_ConvertToType\fR will
+lead to a panic, so to avoid this possibility, the type
+should \fInot\fR be registered.
+.SS "THE UPDATESTRINGPROC FIELD"
+.PP
+The \fIupdateStringProc\fR member contains the address of a function
+called to create a valid string representation
+from a value's internal representation.
+.PP
+.CS
+typedef void \fBTcl_UpdateStringProc\fR(
+        Tcl_Obj *\fIobjPtr\fR);
+.CE
+.PP
+\fIobjPtr\fR's \fIbytes\fR member is always NULL when it is called.
+It must always set \fIbytes\fR non-NULL before returning.
+We require the string representation's byte array
+to have a null after the last byte, at offset \fIlength\fR,
+and to have no null bytes before that; this allows string representations 
+to be treated as conventional null character-terminated C strings.
+These restrictions are easily met by using Tcl's internal UTF encoding
+for the string representation, same as one would do for other
+Tcl routines accepting string values as arguments.
+Storage for the byte array must be allocated in the heap by \fBTcl_Alloc\fR
+or \fBckalloc\fR.  Note that \fIupdateStringProc\fRs must allocate
+enough storage for the string's bytes and the terminating null byte.
+.PP
+The \fIupdateStringProc\fR for Tcl's built-in double type, for example,
+calls Tcl_PrintDouble to write to a buffer of size TCL_DOUBLE_SPACE,
+then allocates and copies the string representation to just enough
+space to hold it.  A pointer to the allocated space is stored in
+the \fIbytes\fR member.
+.PP
+The \fIupdateStringProc\fR member may be set to NULL, if the routines
+making use of the internal representation are written so that the
+string representation is never invalidated.  Failure to meet this
+obligation will lead to panics or crashes when \fBTcl_GetStringFromObj\fR
+or other similar routines ask for the string representation.
+.SS "THE DUPINTREPPROC FIELD"
+.PP
+The \fIdupIntRepProc\fR member contains the address of a function
+called to copy an internal representation from one value to another.
+.PP
+.CS
+typedef void \fBTcl_DupInternalRepProc\fR(
+        Tcl_Obj *\fIsrcPtr\fR,
+        Tcl_Obj *\fIdupPtr\fR);
+.CE
+.PP
+\fIdupPtr\fR's internal representation is made a copy of \fIsrcPtr\fR's
+internal representation.
+Before the call,
+\fIsrcPtr\fR's internal representation is valid and \fIdupPtr\fR's is not.
+\fIsrcPtr\fR's value type determines what
+copying its internal representation means.
+.PP
+For example, the \fIdupIntRepProc\fR for the Tcl integer type
+simply copies an integer.
+The built-in list type's \fIdupIntRepProc\fR uses a far more
+sophisticated scheme to continue sharing storage as much as it
+reasonably can.
+.SS "THE FREEINTREPPROC FIELD"
+.PP
+The \fIfreeIntRepProc\fR member contains the address of a function
+that is called when a value is freed.
+.PP
+.CS
+typedef void \fBTcl_FreeInternalRepProc\fR(
+        Tcl_Obj *\fIobjPtr\fR);
+.CE
+.PP
+The \fIfreeIntRepProc\fR function can deallocate the storage
+for the value's internal representation
+and do other type-specific processing necessary when a value is freed.
+.PP
+For example, the list type's \fIfreeIntRepProc\fR respects
+the storage sharing scheme established by the \fIdupIntRepProc\fR
+so that it only frees storage when the last value sharing it
+is being freed.
+.PP
+The \fIfreeIntRepProc\fR member can be set to NULL
+to indicate that the internal representation does not require freeing.
+The \fIfreeIntRepProc\fR implementation must not access the
+\fIbytes\fR member of the value, since Tcl makes its own internal
+uses of that field during value deletion.  The defined tasks for
+the \fIfreeIntRepProc\fR have no need to consult the \fIbytes\fR
+member.

+.SH DESCRIPTION
+.PP
+The Tcl channel mechanism provides a device-independent and
+platform-independent mechanism for performing buffered input
+and output operations on a variety of file, socket, and device
+types.
+The channel mechanism is extensible to new channel types, by
+providing a low-level channel driver for the new type; the channel driver
+interface is described in the manual entry for \fBTcl_CreateChannel\fR. The
+channel mechanism provides a buffering scheme modeled after
+Unix's standard I/O, and it also allows for nonblocking I/O on
+channels.
+.PP
+The procedures described in this manual entry comprise the C APIs of the
+generic layer of the channel architecture. For a description of the channel
+driver architecture and how to implement channel drivers for new types of
+channels, see the manual entry for \fBTcl_CreateChannel\fR.
+.SH TCL_OPENFILECHANNEL
+.PP
+\fBTcl_OpenFileChannel\fR opens a file specified by \fIfileName\fR and
+returns a channel handle that can be used to perform input and output on
+the file. This API is modeled after the \fBfopen\fR procedure of
+the Unix standard I/O library.
+The syntax and meaning of all arguments is similar to those
+given in the Tcl \fBopen\fR command when opening a file.
+If an error occurs while opening the channel, \fBTcl_OpenFileChannel\fR
+returns NULL and records a POSIX error code that can be
+retrieved with \fBTcl_GetErrno\fR.
+In addition, if \fIinterp\fR is non-NULL, \fBTcl_OpenFileChannel\fR
+leaves an error message in \fIinterp\fR's result after any error.  
+As of Tcl 8.4, the value-based API \fBTcl_FSOpenFileChannel\fR should 
+be used in preference to \fBTcl_OpenFileChannel\fR wherever possible.
+.PP
+The newly created channel is not registered in the supplied interpreter; to
+register it, use \fBTcl_RegisterChannel\fR, described below.
+If one of the standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR was
+previously closed, the act of creating the new channel also assigns it as a
+replacement for the standard channel.
+.SH TCL_OPENCOMMANDCHANNEL
+.PP
+\fBTcl_OpenCommandChannel\fR provides a C-level interface to the
+functions of the \fBexec\fR and \fBopen\fR commands.
+It creates a sequence of subprocesses specified
+by the \fIargv\fR and \fIargc\fR arguments and returns a channel that can
+be used to communicate with these subprocesses.
+The \fIflags\fR argument indicates what sort of communication will
+exist with the command pipeline.
+.PP
+If the \fBTCL_STDIN\fR flag is set then the standard input for the
+first subprocess will be tied to the channel: writing to the channel
+will provide input to the subprocess.  If \fBTCL_STDIN\fR is not set,
+then standard input for the first subprocess will be the same as this
+application's standard input.  If \fBTCL_STDOUT\fR is set then
+standard output from the last subprocess can be read from the channel;
+otherwise it goes to this application's standard output.  If
+\fBTCL_STDERR\fR is set, standard error output for all subprocesses is
+returned to the channel and results in an error when the channel is
+closed; otherwise it goes to this application's standard error.  If
+\fBTCL_ENFORCE_MODE\fR is not set, then \fIargc\fR and \fIargv\fR can
+redirect the stdio handles to override \fBTCL_STDIN\fR,
+\fBTCL_STDOUT\fR, and \fBTCL_STDERR\fR; if it is set, then it is an
+error for argc and argv to override stdio channels for which
+\fBTCL_STDIN\fR, \fBTCL_STDOUT\fR, and \fBTCL_STDERR\fR have been set.
+.PP
+If an error occurs while opening the channel, \fBTcl_OpenCommandChannel\fR
+returns NULL and records a POSIX error code that can be retrieved with
+\fBTcl_GetErrno\fR.
+In addition, \fBTcl_OpenCommandChannel\fR leaves an error message in
+the interpreter's result if \fIinterp\fR is not NULL.
+.PP
+The newly created channel is not registered in the supplied interpreter; to
+register it, use \fBTcl_RegisterChannel\fR, described below.
+If one of the standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR was
+previously closed, the act of creating the new channel also assigns it as a
+replacement for the standard channel.
+.SH TCL_MAKEFILECHANNEL
+.PP
+\fBTcl_MakeFileChannel\fR makes a \fBTcl_Channel\fR from an existing,
+platform-specific, file handle.
+The newly created channel is not registered in the supplied interpreter; to
+register it, use \fBTcl_RegisterChannel\fR, described below.
+If one of the standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR was
+previously closed, the act of creating the new channel also assigns it as a
+replacement for the standard channel.
+.SH TCL_GETCHANNEL
+.PP
+\fBTcl_GetChannel\fR returns a channel given the \fIchannelName\fR used to
+create it with \fBTcl_CreateChannel\fR and a pointer to a Tcl interpreter in
+\fIinterp\fR. If a channel by that name is not registered in that interpreter,
+the procedure returns NULL. If the \fImodePtr\fR argument is not NULL, it
+points at an integer variable that will receive an OR-ed combination of
+\fBTCL_READABLE\fR and \fBTCL_WRITABLE\fR describing whether the channel is
+open for reading and writing.
+.PP
+\fBTcl_GetChannelNames\fR and \fBTcl_GetChannelNamesEx\fR write the
+names of the registered channels to the interpreter's result as a
+list value.  \fBTcl_GetChannelNamesEx\fR will filter these names
+according to the \fIpattern\fR.  If \fIpattern\fR is NULL, then it
+will not do any filtering.  The return value is \fBTCL_OK\fR if no
+errors occurred writing to the result, otherwise it is \fBTCL_ERROR\fR,
+and the error message is left in the interpreter's result.
+.SH TCL_REGISTERCHANNEL
+.PP
+\fBTcl_RegisterChannel\fR adds a channel to the set of channels accessible
+in \fIinterp\fR. After this call, Tcl programs executing in that
+interpreter can refer to the channel in input or output operations using
+the name given in the call to \fBTcl_CreateChannel\fR.  After this call,
+the channel becomes the property of the interpreter, and the caller should
+not call \fBTcl_Close\fR for the channel; the channel will be closed
+automatically when it is unregistered from the interpreter.
+.PP
+Code executing outside of any Tcl interpreter can call
+\fBTcl_RegisterChannel\fR with \fIinterp\fR as NULL, to indicate that it
+wishes to hold a reference to this channel. Subsequently, the channel can
+be registered in a Tcl interpreter and it will only be closed when the
+matching number of calls to \fBTcl_UnregisterChannel\fR have been made.
+This allows code executing outside of any interpreter to safely hold a
+reference to a channel that is also registered in a Tcl interpreter.
+.PP
+This procedure interacts with the code managing the standard
+channels. If no standard channels were initialized before the first
+call to \fBTcl_RegisterChannel\fR, they will get initialized by that
+call. See \fBTcl_StandardChannels\fR for a general treatise about
+standard channels and the behavior of the Tcl library with regard to
+them.
+.SH TCL_UNREGISTERCHANNEL
+.PP
+\fBTcl_UnregisterChannel\fR removes a channel from the set of channels
+accessible in \fIinterp\fR. After this call, Tcl programs will no longer be
+able to use the channel's name to refer to the channel in that interpreter.
+If this operation removed the last registration of the channel in any
+interpreter, the channel is also closed and destroyed.
+.PP
+Code not associated with a Tcl interpreter can call
+\fBTcl_UnregisterChannel\fR with \fIinterp\fR as NULL, to indicate to Tcl
+that it no longer holds a reference to that channel. If this is the last
+reference to the channel, it will now be closed.  \fBTcl_UnregisterChannel\fR
+is very similar to \fBTcl_DetachChannel\fR except that it will also
+close the channel if no further references to it exist.
+.SH TCL_DETACHCHANNEL
+.PP
+\fBTcl_DetachChannel\fR removes a channel from the set of channels
+accessible in \fIinterp\fR. After this call, Tcl programs will no longer be
+able to use the channel's name to refer to the channel in that interpreter.
+Beyond that, this command has no further effect.  It cannot be used on
+the standard channels (\fBstdout\fR, \fBstderr\fR, \fBstdin\fR), and will return
+\fBTCL_ERROR\fR if passed one of those channels.
+.PP
+Code not associated with a Tcl interpreter can call
+\fBTcl_DetachChannel\fR with \fIinterp\fR as NULL, to indicate to Tcl
+that it no longer holds a reference to that channel. If this is the last
+reference to the channel, unlike \fBTcl_UnregisterChannel\fR, 
+it will not be closed.
+.SH TCL_ISSTANDARDCHANNEL
+.PP
+\fBTcl_IsStandardChannel\fR tests whether a channel is one of the
+three standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR.
+If so, it returns 1, otherwise 0.
+.PP
+No attempt is made to check whether the given channel or the standard 
+channels are initialized or otherwise valid.
+.SH TCL_CLOSE
+.PP
+\fBTcl_Close\fR destroys the channel \fIchannel\fR, which must denote a
+currently open channel. The channel should not be registered in any
+interpreter when \fBTcl_Close\fR is called. Buffered output is flushed to
+the channel's output device prior to destroying the channel, and any
+buffered input is discarded.  If this is a blocking channel, the call does
+not return until all buffered data is successfully sent to the channel's
+output device.  If this is a nonblocking channel and there is buffered
+output that cannot be written without blocking, the call returns
+immediately; output is flushed in the background and the channel will be
+closed once all of the buffered data has been output.  In this case errors
+during flushing are not reported.
+.PP
+If the channel was closed successfully, \fBTcl_Close\fR returns \fBTCL_OK\fR.
+If an error occurs, \fBTcl_Close\fR returns \fBTCL_ERROR\fR and records a
+POSIX error code that can be retrieved with \fBTcl_GetErrno\fR.
+If the channel is being closed synchronously and an error occurs during
+closing of the channel and \fIinterp\fR is not NULL, an error message is
+left in the interpreter's result.
+.PP
+Note: it is not safe to call \fBTcl_Close\fR on a channel that has been
+registered using \fBTcl_RegisterChannel\fR; see the documentation for
+\fBTcl_RegisterChannel\fR, above, for details. If the channel has ever
+been given as the \fBchan\fR argument in a call to
+\fBTcl_RegisterChannel\fR, you should instead use
+\fBTcl_UnregisterChannel\fR, which will internally call \fBTcl_Close\fR
+when all calls to \fBTcl_RegisterChannel\fR have been matched by
+corresponding calls to \fBTcl_UnregisterChannel\fR.
+.SH "TCL_READCHARS AND TCL_READ"
+.PP
+\fBTcl_ReadChars\fR consumes bytes from \fIchannel\fR, converting the bytes
+to UTF-8 based on the channel's encoding and storing the produced data in 
+\fIreadObjPtr\fR's string representation.  The return value of
+\fBTcl_ReadChars\fR is the number of characters, up to \fIcharsToRead\fR,
+that were stored in \fIreadObjPtr\fR.  If an error occurs while reading, the
+return value is \-1 and \fBTcl_ReadChars\fR records a POSIX error code that
+can be retrieved with \fBTcl_GetErrno\fR.
+.PP
+Setting \fIcharsToRead\fR to \fB\-1\fR will cause the command to read
+all characters currently available (non-blocking) or everything until
+eof (blocking mode).
+.PP
+The return value may be smaller than the value to read, indicating that less
+data than requested was available.  This is called a \fIshort read\fR.  In
+blocking mode, this can only happen on an end-of-file.  In nonblocking mode,
+a short read can also occur if there is not enough input currently
+available:  \fBTcl_ReadChars\fR returns a short count rather than waiting
+for more data.
+.PP
+If the channel is in blocking mode, a return value of zero indicates an
+end-of-file condition.  If the channel is in nonblocking mode, a return
+value of zero indicates either that no input is currently available or an
+end-of-file condition.  Use \fBTcl_Eof\fR and \fBTcl_InputBlocked\fR to tell
+which of these conditions actually occurred.
+.PP
+\fBTcl_ReadChars\fR translates the various end-of-line representations into
+the canonical \fB\en\fR internal representation according to the current
+end-of-line recognition mode.  End-of-line recognition and the various
+platform-specific modes are described in the manual entry for the Tcl
+\fBfconfigure\fR command.
+.PP
+As a performance optimization, when reading from a channel with the encoding
+\fBbinary\fR, the bytes are not converted to UTF-8 as they are read.
+Instead, they are stored in \fIreadObjPtr\fR's internal representation as a
+byte-array value.  The string representation of this value will only be
+constructed if it is needed (e.g., because of a call to
+\fBTcl_GetStringFromObj\fR).  In this way, byte-oriented data can be read
+from a channel, manipulated by calling \fBTcl_GetByteArrayFromObj\fR and
+related functions, and then written to a channel without the expense of ever
+converting to or from UTF-8.
+.PP
+\fBTcl_Read\fR is similar to \fBTcl_ReadChars\fR, except that it does not do
+encoding conversions, regardless of the channel's encoding.  It is deprecated
+and exists for backwards compatibility with non-internationalized Tcl
+extensions.  It consumes bytes from \fIchannel\fR and stores them in
+\fIreadBuf\fR, performing end-of-line translations on the way.  The return value
+of \fBTcl_Read\fR is the number of bytes, up to \fIbytesToRead\fR, written in
+\fIreadBuf\fR.  The buffer produced by \fBTcl_Read\fR is not null-terminated.
+Its contents are valid from the zeroth position up to and excluding the
+position indicated by the return value.  
+.PP
+\fBTcl_ReadRaw\fR is the same as \fBTcl_Read\fR but does not
+compensate for stacking. While \fBTcl_Read\fR (and the other functions
+in the API) always get their data from the topmost channel in the
+stack the supplied channel is part of, \fBTcl_ReadRaw\fR does
+not. Thus this function is \fBonly\fR usable for transformational
+channel drivers, i.e. drivers used in the middle of a stack of
+channels, to move data from the channel below into the transformation.
+.SH "TCL_GETSOBJ AND TCL_GETS"
+.PP
+\fBTcl_GetsObj\fR consumes bytes from \fIchannel\fR, converting the bytes to
+UTF-8 based on the channel's encoding, until a full line of input has been
+seen.  If the channel's encoding is \fBbinary\fR, each byte read from the
+channel is treated as an individual Unicode character.  All of the
+characters of the line except for the terminating end-of-line character(s)
+are appended to \fIlineObjPtr\fR's string representation.  The end-of-line
+character(s) are read and discarded.
+.PP
+If a line was successfully read, the return value is greater than or equal
+to zero and indicates the number of bytes stored in \fIlineObjPtr\fR.  If an
+error occurs, \fBTcl_GetsObj\fR returns \-1 and records a POSIX error code
+that can be retrieved with \fBTcl_GetErrno\fR.  \fBTcl_GetsObj\fR also
+returns \-1 if the end of the file is reached; the \fBTcl_Eof\fR procedure
+can be used to distinguish an error from an end-of-file condition.
+.PP
+If the channel is in nonblocking mode, the return value can also be \-1 if
+no data was available or the data that was available did not contain an
+end-of-line character.  When \-1 is returned, the \fBTcl_InputBlocked\fR
+procedure may be invoked to determine if the channel is blocked because
+of input unavailability.
+.PP
+\fBTcl_Gets\fR is the same as \fBTcl_GetsObj\fR except the resulting
+characters are appended to the dynamic string given by
+\fIlineRead\fR rather than a Tcl value.
+.SH "TCL_UNGETS"
+.PP
+\fBTcl_Ungets\fR is used to add data to the input queue of a channel,
+at either the head or tail of the queue.  The pointer \fIinput\fR points
+to the data that is to be added.  The length of the input to add is given
+by \fIinputLen\fR.  A non-zero value of \fIaddAtEnd\fR indicates that the
+data is to be added at the end of queue; otherwise it will be added at the
+head of the queue.  If \fIchannel\fR has a
+.QW sticky
+EOF set, no data will be
+added to the input queue.  \fBTcl_Ungets\fR returns \fIinputLen\fR or
+\-1 if an error occurs.
+.SH "TCL_WRITECHARS, TCL_WRITEOBJ, AND TCL_WRITE"
+.PP
+\fBTcl_WriteChars\fR accepts \fIbytesToWrite\fR bytes of character data at
+\fIcharBuf\fR.  The UTF-8 characters in the buffer are converted to the
+channel's encoding and queued for output to \fIchannel\fR.  If
+\fIbytesToWrite\fR is negative, \fBTcl_WriteChars\fR expects \fIcharBuf\fR
+to be null-terminated and it outputs everything up to the null.
+.PP
+Data queued for output may not appear on the output device immediately, due
+to internal buffering.  If the data should appear immediately, call
+\fBTcl_Flush\fR after the call to \fBTcl_WriteChars\fR, or set the 
+\fB\-buffering\fR option on the channel to \fBnone\fR.  If you wish the data
+to appear as soon as a complete line is accepted for output, set the
+\fB\-buffering\fR option on the channel to \fBline\fR mode.
+.PP
+The return value of \fBTcl_WriteChars\fR is a count of how many bytes were
+accepted for output to the channel.  This is either greater than zero to
+indicate success or \-1 to indicate that an error occurred.  If an error
+occurs, \fBTcl_WriteChars\fR records a POSIX error code that may be
+retrieved with \fBTcl_GetErrno\fR.
+.PP
+Newline characters in the output data are translated to platform-specific
+end-of-line sequences according to the \fB\-translation\fR option for the
+channel.  This is done even if the channel has no encoding.
+.PP
+\fBTcl_WriteObj\fR is similar to \fBTcl_WriteChars\fR except it
+accepts a Tcl value whose contents will be output to the channel.  The
+UTF-8 characters in \fIwriteObjPtr\fR's string representation are converted
+to the channel's encoding and queued for output to \fIchannel\fR.  
+As a performance optimization, when writing to a channel with the encoding
+\fBbinary\fR, UTF-8 characters are not converted as they are written.
+Instead, the bytes in \fIwriteObjPtr\fR's internal representation as a
+byte-array value are written to the channel.  The byte-array representation
+of the value will be constructed if it is needed.  In this way,
+byte-oriented data can be read from a channel, manipulated by calling
+\fBTcl_GetByteArrayFromObj\fR and related functions, and then written to a
+channel without the expense of ever converting to or from UTF-8.
+.PP
+\fBTcl_Write\fR is similar to \fBTcl_WriteChars\fR except that it does not do
+encoding conversions, regardless of the channel's encoding.  It is
+deprecated and exists for backwards compatibility with non-internationalized
+Tcl extensions.  It accepts \fIbytesToWrite\fR bytes of data at
+\fIbyteBuf\fR and queues them for output to \fIchannel\fR.  If
+\fIbytesToWrite\fR is negative, \fBTcl_Write\fR expects \fIbyteBuf\fR to be
+null-terminated and it outputs everything up to the null.
+.PP
+\fBTcl_WriteRaw\fR is the same as \fBTcl_Write\fR but does not
+compensate for stacking. While \fBTcl_Write\fR (and the other

+in the stack the supplied channel is part of, \fBTcl_WriteRaw\fR does
+not. Thus this function is \fBonly\fR usable for transformational
+channel drivers, i.e. drivers used in the middle of a stack of
+channels, to move data from the transformation into the channel below
+it.
+.SH TCL_FLUSH
+.PP
+\fBTcl_Flush\fR causes all of the buffered output data for \fIchannel\fR
+to be written to its underlying file or device as soon as possible.
+If the channel is in blocking mode, the call does not return until
+all the buffered data has been sent to the channel or some error occurred.
+The call returns immediately if the channel is nonblocking; it starts
+a background flush that will write the buffered data to the channel
+eventually, as fast as the channel is able to absorb it.
+.PP
+The return value is normally \fBTCL_OK\fR.
+If an error occurs, \fBTcl_Flush\fR returns \fBTCL_ERROR\fR and
+records a POSIX error code that can be retrieved with \fBTcl_GetErrno\fR.
+.SH TCL_SEEK
+.PP
+\fBTcl_Seek\fR moves the access point in \fIchannel\fR where subsequent
+data will be read or written. Buffered output is flushed to the channel and
+buffered input is discarded, prior to the seek operation.
+.PP
+\fBTcl_Seek\fR normally returns the new access point.
+If an error occurs, \fBTcl_Seek\fR returns \-1 and records a POSIX error
+code that can be retrieved with \fBTcl_GetErrno\fR.
+After an error, the access point may or may not have been moved.
+.SH TCL_TELL
+.PP
+\fBTcl_Tell\fR returns the current access point for a channel. The returned
+value is \-1 if the channel does not support seeking.
+.SH TCL_TRUNCATECHANNEL
+.PP
+\fBTcl_TruncateChannel\fR truncates the file underlying \fIchannel\fR
+to a given \fIlength\fR of bytes. It returns \fBTCL_OK\fR if the
+operation succeeded, and \fBTCL_ERROR\fR otherwise.
+.SH TCL_GETCHANNELOPTION
+.PP
+\fBTcl_GetChannelOption\fR retrieves, in \fIoptionValue\fR, the value of one of
+the options currently in effect for a channel, or a list of all options and
+their values.  The \fIchannel\fR argument identifies the channel for which
+to query an option or retrieve all options and their values.
+If \fIoptionName\fR is not NULL, it is the name of the
+option to query; the option's value is copied to the Tcl dynamic string
+denoted by \fIoptionValue\fR. If
+\fIoptionName\fR is NULL, the function stores an alternating list of option
+names and their values in \fIoptionValue\fR, using a series of calls to
+\fBTcl_DStringAppendElement\fR. The various preexisting options and
+their possible values are described in the manual entry for the Tcl
+\fBfconfigure\fR command. Other options can be added by each channel type.
+These channel type specific options are described in the manual entry for
+the Tcl command that creates a channel of that type; for example, the
+additional options for TCP based channels are described in the manual entry
+for the Tcl \fBsocket\fR command.
+The procedure normally returns \fBTCL_OK\fR. If an error occurs, it returns
+\fBTCL_ERROR\fR and calls \fBTcl_SetErrno\fR to store an appropriate POSIX
+error code.
+.SH TCL_SETCHANNELOPTION
+.PP
+\fBTcl_SetChannelOption\fR sets a new value \fInewValue\fR
+for an option \fIoptionName\fR on \fIchannel\fR.
+The procedure normally returns \fBTCL_OK\fR.  If an error occurs,
+it returns \fBTCL_ERROR\fR;  in addition, if \fIinterp\fR is non-NULL,
+\fBTcl_SetChannelOption\fR leaves an error message in the interpreter's result.
+.SH TCL_EOF
+.PP
+\fBTcl_Eof\fR returns a nonzero value if \fIchannel\fR encountered
+an end of file during the last input operation.
+.SH TCL_INPUTBLOCKED
+.PP
+\fBTcl_InputBlocked\fR returns a nonzero value if \fIchannel\fR is in
+nonblocking mode and the last input operation returned less data than
+requested because there was insufficient data available.
+The call always returns zero if the channel is in blocking mode.
+.SH TCL_INPUTBUFFERED
+.PP
+\fBTcl_InputBuffered\fR returns the number of bytes of input currently
+buffered in the internal buffers for a channel. If the channel is not open
+for reading, this function always returns zero.
+.SH TCL_OUTPUTBUFFERED
+.PP
+\fBTcl_OutputBuffered\fR returns the number of bytes of output
+currently buffered in the internal buffers for a channel. If the
+channel is not open for writing, this function always returns zero.
+.SH "PLATFORM ISSUES"
+.PP
+The handles returned from \fBTcl_GetChannelHandle\fR depend on the
+platform and the channel type.  On Unix platforms, the handle is
+always a Unix file descriptor as returned from the \fBopen\fR system
+call.  On Windows platforms, the handle is a file \fBHANDLE\fR when
+the channel was created with \fBTcl_OpenFileChannel\fR,
+\fBTcl_OpenCommandChannel\fR, or \fBTcl_MakeFileChannel\fR.  Other
+channel types may return a different type of handle on Windows
+platforms.

+.SH DESCRIPTION
+.PP
+These functions are convenience procedures for creating
+channels that communicate over TCP sockets.
+The operations on a channel
+are described in the manual entry for \fBTcl_OpenFileChannel\fR.
+.SS TCL_OPENTCPCLIENT
+.PP
+\fBTcl_OpenTcpClient\fR opens a client TCP socket connected to a \fIport\fR
+on a specific \fIhost\fR, and returns a channel that can be used to
+communicate with the server. The host to connect to can be specified either
+as a domain name style name (e.g. \fBwww.sunlabs.com\fR), or as a string
+containing the alphanumeric representation of its four-byte address (e.g.
+\fB127.0.0.1\fR). Use the string \fBlocalhost\fR to connect to a TCP socket on
+the host on which the function is invoked.
+.PP
+The \fImyaddr\fR and \fImyport\fR arguments allow a client to specify an
+address for the local end of the connection.  If \fImyaddr\fR is NULL, then
+an interface is chosen automatically by the operating system.
+If \fImyport\fR is 0, then a port number is chosen at random by
+the operating system.
+.PP
+If \fIasync\fR is zero, the call to \fBTcl_OpenTcpClient\fR returns only
+after the client socket has either successfully connected to the server, or
+the attempted connection has failed.
+If \fIasync\fR is nonzero the socket is connected asynchronously and the
+returned channel may not yet be connected to the server when the call to
+\fBTcl_OpenTcpClient\fR returns. If the channel is in blocking mode and an
+input or output operation is done on the channel before the connection is
+completed or fails, that operation will wait until the connection either
+completes successfully or fails. If the channel is in nonblocking mode, the
+input or output operation will return immediately and a subsequent call to
+\fBTcl_InputBlocked\fR on the channel will return nonzero.
+.PP
+The returned channel is opened for reading and writing.
+If an error occurs in opening the socket, \fBTcl_OpenTcpClient\fR returns
+NULL and records a POSIX error code that can be retrieved
+with \fBTcl_GetErrno\fR.
+In addition, if \fIinterp\fR is non-NULL, an error message
+is left in the interpreter's result.
+.PP
+The newly created channel is not registered in the supplied interpreter; to
+register it, use \fBTcl_RegisterChannel\fR.
+If one of the standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR was
+previously closed, the act of creating the new channel also assigns it as a
+replacement for the standard channel.
+.SS TCL_MAKETCPCLIENTCHANNEL
+.PP
+\fBTcl_MakeTcpClientChannel\fR creates a \fBTcl_Channel\fR around an
+existing, platform specific, handle for a client TCP socket.
+.PP
+The newly created channel is not registered in the supplied interpreter; to
+register it, use \fBTcl_RegisterChannel\fR.
+If one of the standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR was
+previously closed, the act of creating the new channel also assigns it as a
+replacement for the standard channel.
+.SS TCL_OPENTCPSERVER
+.PP
+\fBTcl_OpenTcpServer\fR opens a TCP socket on the local host on a specified
+\fIport\fR and uses the Tcl event mechanism to accept requests from clients
+to connect to it. The \fImyaddr\fR argument specifies the network interface.
+If \fImyaddr\fR is NULL the special address INADDR_ANY should be used to
+allow connections from any network interface.
+Each time a client connects to this socket, Tcl creates a channel
+for the new connection and invokes \fIproc\fR with information about
+the channel. \fIProc\fR must match the following prototype:
+.PP
+.CS
+typedef void \fBTcl_TcpAcceptProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Channel \fIchannel\fR,
+        char *\fIhostName\fR,
+        int \fIport\fR);
+.CE
+.PP
+The \fIclientData\fR argument will be the same as the \fIclientData\fR
+argument to \fBTcl_OpenTcpServer\fR, \fIchannel\fR will be the handle
+for the new channel, \fIhostName\fR points to a string containing
+the name of the client host making the connection, and \fIport\fR
+will contain the client's port number.
+The new channel
+is opened for both input and output. 
+If \fIproc\fR raises an error, the connection is closed automatically.
+\fIProc\fR has no return value, but if it wishes to reject the
+connection it can close \fIchannel\fR.
+.PP
+\fBTcl_OpenTcpServer\fR normally returns a pointer to a channel
+representing the server socket.
+If an error occurs, \fBTcl_OpenTcpServer\fR returns NULL and
+records a POSIX error code that can be retrieved with \fBTcl_GetErrno\fR.
+In addition, if the interpreter is non-NULL, an error message
+is left in the interpreter's result.
+.PP
+The channel returned by \fBTcl_OpenTcpServer\fR cannot be used for
+either input or output.
+It is simply a handle for the socket used to accept connections.
+The caller can close the channel to shut down the server and disallow
+further connections from new clients.
+.PP
+TCP server channels operate correctly only in applications that dispatch
+events through \fBTcl_DoOneEvent\fR or through Tcl commands such as
+\fBvwait\fR; otherwise Tcl will never notice that a connection request from
+a remote client is pending.
+.PP
+The newly created channel is not registered in the supplied interpreter; to
+register it, use \fBTcl_RegisterChannel\fR.
+If one of the standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR was
+previously closed, the act of creating the new channel also assigns it as a
+replacement for the standard channel.
+.SH "PLATFORM ISSUES"
+.PP
+On Unix platforms, the socket handle is a Unix file descriptor as
+returned by the \fBsocket\fR system call.  On the Windows platform, the
+socket handle is a \fBSOCKET\fR as defined in the WinSock API.

+.AP Tcl_PanicProc *panicProc in
+Procedure to report fatal error message and abort.
+.BE
+.SH DESCRIPTION
+.PP
+When the Tcl library detects that its internal data structures are in an
+inconsistent state, or that its C procedures have been called in a
+manner inconsistent with their documentation, it calls \fBTcl_Panic\fR
+to display a message describing the error and abort the process.  The
+\fIformat\fR argument is a format string describing how to format the
+remaining arguments \fIarg\fR into an error message, according to the
+same formatting rules used by the \fBprintf\fR family of functions.  The
+same formatting rules are also used by the built-in Tcl command
+\fBformat\fR.
+.PP
+In a freshly loaded Tcl library, \fBTcl_Panic\fR prints the formatted
+error message to the standard error file of the process, and then
+calls \fBabort\fR to terminate the process.  \fBTcl_Panic\fR does not
+return. On Windows, when a debugger is running, the formatted error
+message is sent to the debugger in stead. If the windows executable
+does not have a stderr channel (e.g. \fBwish.exe\fR), then a
+system dialog box is used to display the panic message.
+.PP
+\fBTcl_SetPanicProc\fR may be used to modify the behavior of
+\fBTcl_Panic\fR.  The \fIpanicProc\fR argument should match the
+type \fBTcl_PanicProc\fR:
+.PP
+.CS
+typedef void \fBTcl_PanicProc\fR(
+        const char *\fBformat\fR,
+        \fBarg\fR, \fBarg\fR,...);
+.CE
+.PP
+After \fBTcl_SetPanicProc\fR returns, any future calls to
+\fBTcl_Panic\fR will call \fIpanicProc\fR, passing along the
+\fIformat\fR and \fIarg\fR arguments. \fIpanicProc\fR should avoid
+making calls into the Tcl library, or into other libraries that may
+call the Tcl library, since the original call to \fBTcl_Panic\fR
+indicates the Tcl library is not in a state of reliable operation.  
+.PP
+The typical use of \fBTcl_SetPanicProc\fR arranges for the error message
+to be displayed or reported in a manner more suitable for the
+application or the platform.
+.PP
+Although the primary callers of \fBTcl_Panic\fR are the procedures of
+the Tcl library, \fBTcl_Panic\fR is a public function and may be called
+by any extension or application that wishes to abort the process and
+have a panic message displayed the same way that panic messages from Tcl
+will be displayed.
+.PP
+\fBTcl_PanicVA\fR is the same as \fBTcl_Panic\fR except that instead of
+taking a variable number of arguments it takes an argument list.

+\fIobjcPtr\fR is updated to a non-zero value, the array returned through this
+must be deallocated using \fBckfree\fR.
+.BE
+.SH DESCRIPTION
+.PP
+The \fBTcl_ParseArgsObjv\fR function provides a system for parsing argument
+lists of the form
+.QW "\fB\-someName \fIsomeValue\fR ..." .
+Such argument lists are commonly found both in the arguments to a program and
+in the arguments to an individual Tcl command. This parser assumes that the
+order of the arguments does not matter, other than in so far as later copies
+of a duplicated option overriding earlier ones.
+.PP
+The argument array is described by the \fIobjcPtr\fR and \fIobjv\fR
+parameters, and an array of unprocessed arguments is returned through the
+\fIobjcPtr\fR and \fIremObjv\fR parameters; if no return of unprocessed
+arguments is desired, the \fIremObjv\fR parameter should be NULL. If any
+problems happen, including if the
+.QW "generate help"
+option is selected, an error message is left in the interpreter result and
+TCL_ERROR is returned. Otherwise, the interpreter result is left unchanged and
+TCL_OK is returned.
+.PP
+The collection of arguments to be parsed is described by the \fIargTable\fR
+parameter. This points to a table of descriptor structures that is terminated
+by an entry with the \fItype\fR field set to TCL_ARGV_END. As convenience, the
+following prototypical entries are provided:
+.TP
+\fBTCL_ARGV_AUTO_HELP\fR
+.
+Enables the argument processor to provide help when passed the argument
+.QW \fB\-help\fR .
+.TP
+\fBTCL_ARGV_AUTO_REST\fR
+.
+Instructs the argument processor that arguments after
+.QW \fB\-\-\fR
+are to be unprocessed.
+.TP
+\fBTCL_ARGV_TABLE_END\fR
+.
+Marks the end of the table of argument descriptors.
+.SS "ARGUMENT DESCRIPTOR ENTRIES"
+.PP
+Each entry of the argument descriptor table must be a structure of type
+\fBTcl_ArgvInfo\fR. The structure is defined as this:
+.PP
+.CS
+typedef struct {
+    int \fItype\fR;
+    const char *\fIkeyStr\fR;
+    void *\fIsrcPtr\fR;
+    void *\fIdstPtr\fR;
+    const char *\fIhelpStr\fR;
+    ClientData \fIclientData\fR;
+} \fBTcl_ArgvInfo\fR;
+.CE
+.PP
+The \fIkeyStr\fR field contains the name of the option; by convention, this
+will normally begin with a
+.QW \fB\-\fR
+character. The \fItype\fR, \fIsrcPtr\fR, \fIdstPtr\fR and \fIclientData\fR
+fields describe the interpretation of the value of the argument, as described
+below. The \fIhelpStr\fR field gives some text that is used to provide help to
+users when they request it.
+.PP
+As noted above, the \fItype\fR field is used to describe the interpretation of
+the argument's value. The following values are acceptable values for
+\fItype\fR:
+.TP
+\fBTCL_ARGV_CONSTANT\fR
+.
+The argument does not take any following value argument. If this argument is
+present, the int pointed to by the \fIsrcPtr\fR field is copied to the
+\fIdstPtr\fR field. The \fIclientData\fR field is ignored.
+.TP
+\fBTCL_ARGV_END\fR
+.
+This value marks the end of all option descriptors in the table. All other
+fields are ignored.
+.TP
+\fBTCL_ARGV_FLOAT\fR
+.
+This argument takes a following floating point value argument. The value (once
+parsed by \fBTcl_GetDoubleFromObj\fR) will be stored as a double-precision
+value in the variable pointed to by the \fIdstPtr\fR field. The \fIsrcPtr\fR
+and \fIclientData\fR fields are ignored.
+.TP
+\fBTCL_ARGV_FUNC\fR
+.
+This argument optionally takes a following value argument; it is up to the
+handler callback function passed in \fIsrcPtr\fR to decide. That function will
+have the following signature:
+.RS
+.PP
+.CS
+typedef int (\fBTcl_ArgvFuncProc\fR)(
+        ClientData \fIclientData\fR,
+        Tcl_Obj *\fIobjPtr\fR,
+        void *\fIdstPtr\fR);
+.CE
+.PP
+The result is a boolean value indicating whether to consume the following
+argument. The \fIclientData\fR is the value from the table entry, the
+\fIobjPtr\fR is the value that represents the following argument or NULL if
+there are no following arguments at all, and the \fIdstPtr\fR argument to the
+\fBTcl_ArgvFuncProc\fR is the location to write the parsed value to.
+.RE
+.TP
+\fBTCL_ARGV_GENFUNC\fR
+.
+This argument takes zero or more following arguments; the handler callback
+function passed in \fIsrcPtr\fR returns how many (or a negative number to
+signal an error, in which case it should also set the interpreter result). The
+function will have the following signature:
+.RS
+.PP
+.CS
+typedef int (\fBTcl_ArgvGenFuncProc\fR)(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        int \fIobjc\fR,
+        Tcl_Obj *const *\fIobjv\fR,
+        void *\fIdstPtr\fR);
+.CE
+.PP
+The \fIclientData\fR is the value from the table entry, the \fIinterp\fR is
+where to store any error messages, the \fIkeyStr\fR is the name of the
+argument, \fIobjc\fR and \fIobjv\fR describe an array of all the remaining
+arguments, and \fIdstPtr\fR argument to the \fBTcl_ArgvGenFuncProc\fR is the
+location to write the parsed value (or values) to.
+.RE
+.TP
+\fBTCL_ARGV_HELP\fR
+.
+This special argument does not take any following value argument, but instead
+causes \fBTcl_ParseArgsObjv\fR to generate an error message describing the
+arguments supported. All other fields except the \fIhelpStr\fR field are
+ignored.
+.TP
+\fBTCL_ARGV_INT\fR
+.
+This argument takes a following integer value argument. The value (once parsed
+by \fBTcl_GetIntFromObj\fR) will be stored as an int in the variable pointed
+to by the \fIdstPtr\fR field. The \fIsrcPtr\fR field is ignored.
+.TP
+\fBTCL_ARGV_REST\fR
+.
+This special argument does not take any following value argument, but instead
+marks all following arguments to be left unprocessed. The \fIsrcPtr\fR,
+\fIdstPtr\fR and \fIclientData\fR fields are ignored.
+.TP
+\fBTCL_ARGV_STRING\fR
+.
+This argument takes a following string value argument. A pointer to the string
+will be stored at \fIdstPtr\fR; the string inside will have a lifetime linked
+to the lifetime of the string representation of the argument value that it
+came from, and so should be copied if it needs to be retained. The
+\fIsrcPtr\fR and \fIclientData\fR fields are ignored.

+.SH DESCRIPTION
+.PP
+These procedures parse Tcl commands or portions of Tcl commands such as
+expressions or references to variables.
+Each procedure takes a pointer to a script (or portion thereof)
+and fills in the structure pointed to by \fIparsePtr\fR
+with a collection of tokens describing the information that was parsed.
+The procedures normally return \fBTCL_OK\fR.
+However, if an error occurs then they return \fBTCL_ERROR\fR,
+leave an error message in \fIinterp\fR's result
+(if \fIinterp\fR is not NULL),
+and leave nothing in \fIparsePtr\fR.
+.PP
+\fBTcl_ParseCommand\fR is a procedure that parses Tcl
+scripts.  Given a pointer to a script, it
+parses the first command from the script.  If the command was parsed
+successfully, \fBTcl_ParseCommand\fR returns \fBTCL_OK\fR and fills in the
+structure pointed to by \fIparsePtr\fR with information about the
+structure of the command (see below for details).
+If an error occurred in parsing the command then
+\fBTCL_ERROR\fR is returned, an error message is left in \fIinterp\fR's
+result, and no information is left at \fI*parsePtr\fR.
+.PP
+\fBTcl_ParseExpr\fR parses Tcl expressions.
+Given a pointer to a script containing an expression,
+\fBTcl_ParseExpr\fR parses the expression.
+If the expression was parsed successfully,
+\fBTcl_ParseExpr\fR returns \fBTCL_OK\fR and fills in the
+structure pointed to by \fIparsePtr\fR with information about the
+structure of the expression (see below for details).
+If an error occurred in parsing the command then
+\fBTCL_ERROR\fR is returned, an error message is left in \fIinterp\fR's
+result, and no information is left at \fI*parsePtr\fR.
+.PP
+\fBTcl_ParseBraces\fR parses a string or command argument
+enclosed in braces such as
+\fB{hello}\fR or \fB{string \et with \et tabs}\fR
+from the beginning of its argument \fIstart\fR.
+The first character of \fIstart\fR must be \fB{\fR. 
+If the braced string was parsed successfully,
+\fBTcl_ParseBraces\fR returns \fBTCL_OK\fR,
+fills in the structure pointed to by \fIparsePtr\fR
+with information about the structure of the string
+(see below for details),
+and stores a pointer to the character just after the terminating \fB}\fR
+in the location given by \fI*termPtr\fR.
+If an error occurs while parsing the string
+then \fBTCL_ERROR\fR is returned,
+an error message is left in \fIinterp\fR's result,
+and no information is left at \fI*parsePtr\fR or \fI*termPtr\fR.
+.PP
+\fBTcl_ParseQuotedString\fR parses a double-quoted string such as
+\fB"sum is [expr {$a+$b}]"\fR
+from the beginning of the argument \fIstart\fR.
+The first character of \fIstart\fR must be \fB\N'34'\fR. 
+If the double-quoted string was parsed successfully,
+\fBTcl_ParseQuotedString\fR returns \fBTCL_OK\fR,
+fills in the structure pointed to by \fIparsePtr\fR
+with information about the structure of the string
+(see below for details),
+and stores a pointer to the character just after the terminating \fB\N'34'\fR
+in the location given by \fI*termPtr\fR.
+If an error occurs while parsing the string
+then \fBTCL_ERROR\fR is returned,
+an error message is left in \fIinterp\fR's result,
+and no information is left at \fI*parsePtr\fR or \fI*termPtr\fR.
+.PP
+\fBTcl_ParseVarName\fR parses a Tcl variable reference such as
+\fB$abc\fR or \fB$x([expr {$index + 1}])\fR from the beginning of its
+\fIstart\fR argument.
+The first character of \fIstart\fR must be \fB$\fR. 
+If a variable name was parsed successfully, \fBTcl_ParseVarName\fR
+returns \fBTCL_OK\fR and fills in the structure pointed to by
+\fIparsePtr\fR with information about the structure of the variable name
+(see below for details).  If an error
+occurs while parsing the command then \fBTCL_ERROR\fR is returned, an
+error message is left in \fIinterp\fR's result (if \fIinterp\fR is not
+NULL), and no information is left at \fI*parsePtr\fR.
+.PP
+\fBTcl_ParseVar\fR parse a Tcl variable reference such as \fB$abc\fR
+or \fB$x([expr {$index + 1}])\fR from the beginning of its \fIstart\fR
+argument.  The first character of \fIstart\fR must be \fB$\fR.  If
+the variable name is parsed successfully, \fBTcl_ParseVar\fR returns a
+pointer to the string value of the variable.  If an error occurs while
+parsing, then NULL is returned and an error message is left in
+\fIinterp\fR's result.
+.PP
+The information left at \fI*parsePtr\fR
+by \fBTcl_ParseCommand\fR, \fBTcl_ParseExpr\fR, \fBTcl_ParseBraces\fR,
+\fBTcl_ParseQuotedString\fR, and \fBTcl_ParseVarName\fR
+may include dynamically allocated memory.
+If these five parsing procedures return \fBTCL_OK\fR
+then the caller must invoke \fBTcl_FreeParse\fR to release
+the storage at \fI*parsePtr\fR.
+These procedures ignore any existing information in
+\fI*parsePtr\fR (unless \fIappend\fR is non-zero),
+so if repeated calls are being made to any of them
+then \fBTcl_FreeParse\fR must be invoked once after each call.
+.PP
+\fBTcl_EvalTokensStandard\fR evaluates a sequence of parse tokens from
+a Tcl_Parse structure.  The tokens typically consist
+of all the tokens in a word or all the tokens that make up the index for
+a reference to an array variable.  \fBTcl_EvalTokensStandard\fR performs the
+substitutions requested by the tokens and concatenates the
+resulting values. 
+The return value from \fBTcl_EvalTokensStandard\fR is a Tcl completion
+code with one of the values \fBTCL_OK\fR, \fBTCL_ERROR\fR,
+\fBTCL_RETURN\fR, \fBTCL_BREAK\fR, or \fBTCL_CONTINUE\fR, or possibly
+some other integer value originating in an extension.
+In addition, a result value or error message is left in \fIinterp\fR's
+result; it can be retrieved using \fBTcl_GetObjResult\fR.
+.PP
+\fBTcl_EvalTokens\fR differs from \fBTcl_EvalTokensStandard\fR only in
+the return convention used: it returns the result in a new Tcl_Obj.
+The reference count of the value returned as result has been
+incremented, so the caller must
+invoke \fBTcl_DecrRefCount\fR when it is finished with the value.
+If an error or other exception occurs while evaluating the tokens
+(such as a reference to a non-existent variable) then the return value
+is NULL and an error message is left in \fIinterp\fR's result. The use
+of \fBTcl_EvalTokens\fR is deprecated.
+.SH "TCL_PARSE STRUCTURE"
+.PP
+\fBTcl_ParseCommand\fR, \fBTcl_ParseExpr\fR, \fBTcl_ParseBraces\fR,
+\fBTcl_ParseQuotedString\fR, and \fBTcl_ParseVarName\fR
+return parse information in two data structures, Tcl_Parse and Tcl_Token:
+.PP
+.CS
+typedef struct Tcl_Parse {
+    const char *\fIcommentStart\fR;
+    int \fIcommentSize\fR;
+    const char *\fIcommandStart\fR;
+    int \fIcommandSize\fR;
+    int \fInumWords\fR;
+    Tcl_Token *\fItokenPtr\fR;
+    int \fInumTokens\fR;
+    ...
+} \fBTcl_Parse\fR;
+
+typedef struct Tcl_Token {
+    int \fItype\fR;
+    const char *\fIstart\fR;
+    int \fIsize\fR;
+    int \fInumComponents\fR;
+} \fBTcl_Token\fR;
+.CE
+.PP
+The first five fields of a Tcl_Parse structure
+are filled in only by \fBTcl_ParseCommand\fR.
+These fields are not used by the other parsing procedures.
+.PP
+\fBTcl_ParseCommand\fR fills in a Tcl_Parse structure
+with information that describes one Tcl command and any comments that
+precede the command.
+If there are comments,
+the \fIcommentStart\fR field points to the \fB#\fR character that begins
+the first comment and \fIcommentSize\fR indicates the number of bytes
+in all of the comments preceding the command, including the newline
+character that terminates the last comment.
+If the command is not preceded by any comments, \fIcommentSize\fR is 0.
+\fBTcl_ParseCommand\fR also sets the \fIcommandStart\fR field
+to point to the first character of the first
+word in the command (skipping any comments and leading space) and 
+\fIcommandSize\fR gives the total number of bytes in the command,
+including the character pointed to by \fIcommandStart\fR up to and
+including the newline, close bracket, or semicolon character that
+terminates the command.  The \fInumWords\fR field gives the
+total number of words in the command.
+.PP
+All parsing procedures set the remaining fields,
+\fItokenPtr\fR and \fInumTokens\fR.
+The \fItokenPtr\fR field points to the first in an array of Tcl_Token
+structures that describe the components of the entity being parsed.
+The \fInumTokens\fR field gives the total number of tokens
+present in the array.
+Each token contains four fields.
+The \fItype\fR field selects one of several token types
+that are described below.  The \fIstart\fR field
+points to the first character in the token and the \fIsize\fR field
+gives the total number of characters in the token.  Some token types,
+such as \fBTCL_TOKEN_WORD\fR and \fBTCL_TOKEN_VARIABLE\fR, consist of
+several component tokens, which immediately follow the parent token;
+the \fInumComponents\fR field describes how many of these there are.
+The \fItype\fR field has one of the following values:
+.TP 20
+\fBTCL_TOKEN_WORD\fR
+.
+This token ordinarily describes one word of a command
+but it may also describe a quoted or braced string in an expression.
+The token describes a component of the script that is
+the result of concatenating together a sequence of subcomponents,
+each described by a separate subtoken.
+The token starts with the first non-blank
+character of the component (which may be a double-quote or open brace)
+and includes all characters in the component up to but not including the
+space, semicolon, close bracket, close quote, or close brace that
+terminates the component.  The \fInumComponents\fR field counts the total
+number of sub-tokens that make up the word, including sub-tokens
+of \fBTCL_TOKEN_VARIABLE\fR and \fBTCL_TOKEN_BS\fR tokens.
+.TP
+\fBTCL_TOKEN_SIMPLE_WORD\fR
+.
+This token has the same meaning as \fBTCL_TOKEN_WORD\fR, except that
+the word is guaranteed to consist of a single \fBTCL_TOKEN_TEXT\fR
+sub-token.  The \fInumComponents\fR field is always 1.
+.TP
+\fBTCL_TOKEN_EXPAND_WORD\fR
+.
+This token has the same meaning as \fBTCL_TOKEN_WORD\fR, except that
+the command parser notes this word began with the expansion
+prefix \fB{*}\fR, indicating that after substitution,
+the list value of this word should be expanded to form multiple
+arguments in command evaluation.  This
+token type can only be created by Tcl_ParseCommand.
+.TP
+\fBTCL_TOKEN_TEXT\fR
+.
+The token describes a range of literal text that is part of a word.
+The \fInumComponents\fR field is always 0.
+.TP
+\fBTCL_TOKEN_BS\fR
+.
+The token describes a backslash sequence such as \fB\en\fR or \fB\e0xa3\fR.
+The \fInumComponents\fR field is always 0.
+.TP
+\fBTCL_TOKEN_COMMAND\fR
+.
+The token describes a command whose result must be substituted into
+the word.  The token includes the square brackets that surround the
+command.  The \fInumComponents\fR field is always 0 (the nested command
+is not parsed; call \fBTcl_ParseCommand\fR recursively if you want to
+see its tokens).
+.TP
+\fBTCL_TOKEN_VARIABLE\fR
+.
+The token describes a variable substitution, including the
+\fB$\fR, variable name, and array index (if there is one) up through the
+close parenthesis that terminates the index.  This token is followed
+by one or more additional tokens that describe the variable name and
+array index.  If \fInumComponents\fR  is 1 then the variable is a
+scalar and the next token is a \fBTCL_TOKEN_TEXT\fR token that gives the
+variable name.  If \fInumComponents\fR is greater than 1 then the
+variable is an array: the first sub-token is a \fBTCL_TOKEN_TEXT\fR
+token giving the array name and the remaining sub-tokens are
+\fBTCL_TOKEN_TEXT\fR, \fBTCL_TOKEN_BS\fR, \fBTCL_TOKEN_COMMAND\fR, and
+\fBTCL_TOKEN_VARIABLE\fR tokens that must be concatenated to produce the
+array index. The \fInumComponents\fR field includes nested sub-tokens
+that are part of \fBTCL_TOKEN_VARIABLE\fR tokens in the array index.
+.TP
+\fBTCL_TOKEN_SUB_EXPR\fR
+.
+The token describes one subexpression of an expression
+(or an entire expression).
+A subexpression may consist of a value
+such as an integer literal, variable substitution,
+or parenthesized subexpression;
+it may also consist of an operator and its operands.
+The token starts with the first non-blank character of the subexpression
+up to but not including the space, brace, close-paren, or bracket
+that terminates the subexpression.
+This token is followed by one or more additional tokens
+that describe the subexpression.
+If the first sub-token after the \fBTCL_TOKEN_SUB_EXPR\fR token
+is a \fBTCL_TOKEN_OPERATOR\fR token,
+the subexpression consists of an operator and its token operands.
+If the operator has no operands, the subexpression consists of
+just the \fBTCL_TOKEN_OPERATOR\fR token.
+Each operand is described by a \fBTCL_TOKEN_SUB_EXPR\fR token.
+Otherwise, the subexpression is a value described by
+one of the token types \fBTCL_TOKEN_WORD\fR, \fBTCL_TOKEN_TEXT\fR,
+\fBTCL_TOKEN_BS\fR, \fBTCL_TOKEN_COMMAND\fR, 
+\fBTCL_TOKEN_VARIABLE\fR, and \fBTCL_TOKEN_SUB_EXPR\fR.
+The \fInumComponents\fR field
+counts the total number of sub-tokens that make up the subexpression;
+this includes the sub-tokens for any nested \fBTCL_TOKEN_SUB_EXPR\fR tokens.
+.TP
+\fBTCL_TOKEN_OPERATOR\fR
+.
+The token describes one operator of an expression
+such as \fB&&\fR or \fBhypot\fR.
+A \fBTCL_TOKEN_OPERATOR\fR token is always preceded by a
+\fBTCL_TOKEN_SUB_EXPR\fR token
+that describes the operator and its operands;
+the \fBTCL_TOKEN_SUB_EXPR\fR token's \fInumComponents\fR field
+can be used to determine the number of operands.
+A binary operator such as \fB*\fR
+is followed by two \fBTCL_TOKEN_SUB_EXPR\fR tokens
+that describe its operands.
+A unary operator like \fB\-\fR
+is followed by a single \fBTCL_TOKEN_SUB_EXPR\fR token
+for its operand.
+If the operator is a math function such as \fBlog10\fR,
+the \fBTCL_TOKEN_OPERATOR\fR token will give its name and
+the following \fBTCL_TOKEN_SUB_EXPR\fR tokens will describe
+its operands;
+if there are no operands (as with \fBrand\fR),
+no \fBTCL_TOKEN_SUB_EXPR\fR tokens follow.
+There is one trinary operator, \fB?\fR,
+that appears in if-then-else subexpressions
+such as \fIx\fB?\fIy\fB:\fIz\fR;
+in this case, the \fB?\fR \fBTCL_TOKEN_OPERATOR\fR token
+is followed by three \fBTCL_TOKEN_SUB_EXPR\fR tokens for the operands
+\fIx\fR, \fIy\fR, and \fIz\fR.
+The \fInumComponents\fR field for a \fBTCL_TOKEN_OPERATOR\fR token
+is always 0.
+.PP
+After \fBTcl_ParseCommand\fR returns, the first token pointed to by
+the \fItokenPtr\fR field of the
+Tcl_Parse structure always has type \fBTCL_TOKEN_WORD\fR or
+\fBTCL_TOKEN_SIMPLE_WORD\fR or \fBTCL_TOKEN_EXPAND_WORD\fR.  
+It is followed by the sub-tokens
+that must be concatenated to produce the value of that word.
+The next token is the \fBTCL_TOKEN_WORD\fR or \fBTCL_TOKEN_SIMPLE_WORD\fR
+of \fBTCL_TOKEN_EXPAND_WORD\fR token for the second word,
+followed by sub-tokens for that
+word, and so on until all \fInumWords\fR have been accounted
+for.
+.PP
+After \fBTcl_ParseExpr\fR returns, the first token pointed to by
+the \fItokenPtr\fR field of the
+Tcl_Parse structure always has type \fBTCL_TOKEN_SUB_EXPR\fR.
+It is followed by the sub-tokens that must be evaluated
+to produce the value of the expression.
+Only the token information in the Tcl_Parse structure
+is modified: the \fIcommentStart\fR, \fIcommentSize\fR,
+\fIcommandStart\fR, and \fIcommandSize\fR fields are not modified
+by \fBTcl_ParseExpr\fR.
+.PP
+After \fBTcl_ParseBraces\fR returns,
+the array of tokens pointed to by the \fItokenPtr\fR field of the
+Tcl_Parse structure will contain a single \fBTCL_TOKEN_TEXT\fR token
+if the braced string does not contain any backslash-newlines.
+If the string does contain backslash-newlines,
+the array of tokens will contain one or more
+\fBTCL_TOKEN_TEXT\fR or \fBTCL_TOKEN_BS\fR sub-tokens
+that must be concatenated to produce the value of the string.
+If the braced string was just \fB{}\fR
+(that is, the string was empty),
+the single \fBTCL_TOKEN_TEXT\fR token will have a \fIsize\fR field
+containing zero;
+this ensures that at least one token appears
+to describe the braced string.
+Only the token information in the Tcl_Parse structure
+is modified: the \fIcommentStart\fR, \fIcommentSize\fR,
+\fIcommandStart\fR, and \fIcommandSize\fR fields are not modified
+by \fBTcl_ParseBraces\fR.
+.PP
+After \fBTcl_ParseQuotedString\fR returns,
+the array of tokens pointed to by the \fItokenPtr\fR field of the
+Tcl_Parse structure depends on the contents of the quoted string.
+It will consist of one or more \fBTCL_TOKEN_TEXT\fR, \fBTCL_TOKEN_BS\fR,
+\fBTCL_TOKEN_COMMAND\fR, and \fBTCL_TOKEN_VARIABLE\fR sub-tokens.
+The array always contains at least one token;
+for example, if the argument \fIstart\fR is empty,
+the array returned consists of a single \fBTCL_TOKEN_TEXT\fR token
+with a zero \fIsize\fR field.
+Only the token information in the Tcl_Parse structure
+is modified: the \fIcommentStart\fR, \fIcommentSize\fR,
+\fIcommandStart\fR, and \fIcommandSize\fR fields are not modified.
+.PP
+After \fBTcl_ParseVarName\fR returns, the first token pointed to by
+the \fItokenPtr\fR field of the
+Tcl_Parse structure always has type \fBTCL_TOKEN_VARIABLE\fR.  It
+is followed by the sub-tokens that make up the variable name as
+described above.  The total length of the variable name is
+contained in the \fIsize\fR field of the first token.
+As in \fBTcl_ParseExpr\fR,
+only the token information in the Tcl_Parse structure
+is modified by \fBTcl_ParseVarName\fR:
+the \fIcommentStart\fR, \fIcommentSize\fR,
+\fIcommandStart\fR, and \fIcommandSize\fR fields are not modified.
+.PP
+All of the character pointers in the
+Tcl_Parse and Tcl_Token structures refer
+to characters in the \fIstart\fR argument passed to
+\fBTcl_ParseCommand\fR, \fBTcl_ParseExpr\fR, \fBTcl_ParseBraces\fR,
+\fBTcl_ParseQuotedString\fR, and \fBTcl_ParseVarName\fR.
+.PP
+There are additional fields in the Tcl_Parse structure after the
+\fInumTokens\fR field, but these are for the private use of
+\fBTcl_ParseCommand\fR, \fBTcl_ParseExpr\fR, \fBTcl_ParseBraces\fR,
+\fBTcl_ParseQuotedString\fR, and \fBTcl_ParseVarName\fR; they should not be
+referenced by code outside of these procedures.

+.PP
+These procedures provide C-level interfaces to Tcl's package and
+version management facilities.
+.PP
+\fBTcl_PkgRequire\fR is equivalent to the \fBpackage require\fR
+command, \fBTcl_PkgPresent\fR is equivalent to the \fBpackage present\fR
+command, and \fBTcl_PkgProvide\fR is equivalent to the
+\fBpackage provide\fR command.
+.PP
+See the documentation for the Tcl commands for details on what these
+procedures do.
+.PP
+If \fBTcl_PkgPresent\fR or \fBTcl_PkgRequire\fR complete successfully
+they return a pointer to the version string for the version of the package
+that is provided in the interpreter (which may be different than 
+\fIversion\fR); if an error occurs they return NULL and leave an error 
+message in the interpreter's result.
+.PP
+\fBTcl_PkgProvide\fR returns \fBTCL_OK\fR if it completes successfully;
+if an error occurs it returns \fBTCL_ERROR\fR and leaves an error message
+in the interpreter's result.
+.PP
+\fBTcl_PkgProvideEx\fR, \fBTcl_PkgPresentEx\fR and \fBTcl_PkgRequireEx\fR
+allow the setting and retrieving of the client data associated with
+the package. In all other respects they are equivalent to the matching

+.AP Tcl_FreeProc *freeProc in
+Procedure to invoke to free \fIclientData\fR.
+.BE
+.SH DESCRIPTION
+.PP
+These three procedures help implement a simple reference count mechanism
+for managing storage.  They are designed to solve a problem
+having to do with widget deletion, but are also useful in many other
+situations.  When a widget is deleted, its
+widget record (the structure holding information specific to the
+widget) must be returned to the storage allocator.
+However, it is possible that the widget record is in active use
+by one of the procedures on the stack at the time of the deletion.
+This can happen, for example, if the command associated with a button
+widget causes the button to be destroyed:  an X event causes an
+event-handling C procedure in the button to be invoked, which in
+turn causes the button's associated Tcl command to be executed,
+which in turn causes the button to be deleted, which in turn causes
+the button's widget record to be de-allocated.
+Unfortunately, when the Tcl command returns, the button's
+event-handling procedure will need to reference the
+button's widget record.
+Because of this, the widget record must not be freed as part of the
+deletion, but must be retained until the event-handling procedure has
+finished with it.
+In other situations where the widget is deleted, it may be possible
+to free the widget record immediately.
+.PP
+\fBTcl_Preserve\fR and \fBTcl_Release\fR
+implement short-term reference counts for their \fIclientData\fR
+argument.
+The \fIclientData\fR argument identifies an object and usually
+consists of the address of a structure.
+The reference counts guarantee that an object will not be freed
+until each call to \fBTcl_Preserve\fR for the object has been
+matched by calls to \fBTcl_Release\fR.
+There may be any number of unmatched \fBTcl_Preserve\fR calls
+in effect at once.
+.PP
+\fBTcl_EventuallyFree\fR is invoked to free up its \fIclientData\fR
+argument.
+It checks to see if there are unmatched \fBTcl_Preserve\fR calls
+for the object.
+If not, then \fBTcl_EventuallyFree\fR calls \fIfreeProc\fR immediately.
+Otherwise \fBTcl_EventuallyFree\fR records the fact that \fIclientData\fR
+needs eventually to be freed.
+When all calls to \fBTcl_Preserve\fR have been matched with
+calls to \fBTcl_Release\fR then \fIfreeProc\fR will be called by
+\fBTcl_Release\fR to do the cleanup.
+.PP
+All the work of freeing the object is carried out by \fIfreeProc\fR.
+\fIFreeProc\fR must have arguments and result that match the
+type \fBTcl_FreeProc\fR:
+.PP
+.CS
+typedef void \fBTcl_FreeProc\fR(
+        char *\fIblockPtr\fR);
+.CE
+.PP
+The \fIblockPtr\fR argument to \fIfreeProc\fR will be the
+same as the \fIclientData\fR argument to \fBTcl_EventuallyFree\fR.
+The type of \fIblockPtr\fR (\fBchar *\fR) is different than the type of the
+\fIclientData\fR argument to \fBTcl_EventuallyFree\fR for historical
+reasons, but the value is the same.
+.PP
+When the \fIclientData\fR argument to \fBTcl_EventuallyFree\fR
+refers to storage allocated and returned by a prior call to
+\fBTcl_Alloc\fR, \fBckalloc\fR, or another function of the Tcl library,
+then the \fIfreeProc\fR argument should be given the special value of
+\fBTCL_DYNAMIC\fR.
+.PP
+This mechanism can be used to solve the problem described above
+by placing \fBTcl_Preserve\fR and \fBTcl_Release\fR calls around
+actions that may cause undesired storage re-allocation.  The
+mechanism is intended only for short-term use (i.e. while procedures
+are pending on the stack);  it will not work efficiently as a
+mechanism for long-term reference counts.
+The implementation does not depend in any way on the internal
+structure of the objects being freed;  it keeps the reference
+counts in a separate structure.

+.BE
+.SH DESCRIPTION
+.PP
+The function described here has its base in TIP 59 and provides
+extensions with support for the embedding of configuration
+information into their binary library and the generation of a
+Tcl-level interface for querying this information.
+.PP
+To embed configuration information into their binary library an
+extension has to define a non-volatile array of Tcl_Config entries in
+one if its source files and then call \fBTcl_RegisterConfig\fR to
+register that information.
+.PP
+\fBTcl_RegisterConfig\fR takes four arguments; first, a reference to
+the interpreter we are registering the information with, second, the
+name of the package registering its configuration information, third,
+a pointer to an array of structures, and fourth a string declaring the
+encoding used by the configuration values.
+.PP
+The string \fIvalEncoding\fR contains the name of an encoding known to
+Tcl.  All these names are use only characters in the ASCII subset of
+UTF-8 and are thus implicitly in the UTF-8 encoding. It is expected
+that keys are legible English text and therefore using the ASCII
+subset of UTF-8. In other words, they are expected to be in UTF-8
+too. The values associated with the keys can be any string
+however. For these the contents of \fIvalEncoding\fR define which
+encoding was used to represent the characters of the strings.
+.PP
+Each element of the \fIconfiguration\fR array refers to two strings
+containing the key and the value associated with that key. The end of
+the array is signaled by either an empty key or a key identical to
+NULL. The function makes \fBno\fR copy of the \fIconfiguration\fR
+array. This means that the caller has to make sure that the memory
+holding this array is never released. This is the meaning behind the
+word \fBnon-volatile\fR used earlier. The easiest way to accomplish
+this is to define a global static array of Tcl_Config entries. See the file
+.QW generic/tclPkgConfig.c
+in the sources of the Tcl core for an example.
+.PP
+When called \fBTcl_RegisterConfig\fR will
+.IP (1)
+create a namespace having the provided \fIpkgName\fR, if not yet
+existing.
+.IP (2)
+create the command \fBpkgconfig\fR in that namespace and link it to
+the provided information so that the keys from \fIconfiguration\fR and
+their associated values can be retrieved through calls to
+\fBpkgconfig\fR.
+.PP
+The command \fBpkgconfig\fR will provide two subcommands, \fBlist\fR
+and \fBget\fR:
+.RS
+.TP
+::\fIpkgName\fR::\fBpkgconfig\fR list
+Returns a list containing the names of all defined keys.
+.TP
+::\fIpkgName\fR::\fBpkgconfig\fR get \fIkey\fR
+Returns the configuration value associated with the specified
+\fIkey\fR.

+.SH DESCRIPTION
+.PP
+\fBTcl_RegExpMatch\fR determines whether its \fIpattern\fR argument
+matches \fIregexp\fR, where \fIregexp\fR is interpreted
+as a regular expression using the rules in the \fBre_syntax\fR
+reference page. 
+If there is a match then \fBTcl_RegExpMatch\fR returns 1.
+If there is no match then \fBTcl_RegExpMatch\fR returns 0.
+If an error occurs in the matching process (e.g. \fIpattern\fR
+is not a valid regular expression) then \fBTcl_RegExpMatch\fR
+returns \-1 and leaves an error message in the interpreter result.
+\fBTcl_RegExpMatchObj\fR is similar to \fBTcl_RegExpMatch\fR except it
+operates on the Tcl values \fItextObj\fR and \fIpatObj\fR instead of
+UTF strings. 
+\fBTcl_RegExpMatchObj\fR is generally more efficient than
+\fBTcl_RegExpMatch\fR, so it is the preferred interface.
+.PP
+\fBTcl_RegExpCompile\fR, \fBTcl_RegExpExec\fR, and \fBTcl_RegExpRange\fR
+provide lower-level access to the regular expression pattern matcher.
+\fBTcl_RegExpCompile\fR compiles a regular expression string into
+the internal form used for efficient pattern matching.
+The return value is a token for this compiled form, which can be
+used in subsequent calls to \fBTcl_RegExpExec\fR or \fBTcl_RegExpRange\fR.
+If an error occurs while compiling the regular expression then
+\fBTcl_RegExpCompile\fR returns NULL and leaves an error message
+in the interpreter result.
+Note:  the return value from \fBTcl_RegExpCompile\fR is only valid
+up to the next call to \fBTcl_RegExpCompile\fR;  it is not safe to
+retain these values for long periods of time.
+.PP
+\fBTcl_RegExpExec\fR executes the regular expression pattern matcher.
+It returns 1 if \fItext\fR contains a range of characters that
+match \fIregexp\fR, 0 if no match is found, and
+\-1 if an error occurs.
+In the case of an error, \fBTcl_RegExpExec\fR leaves an error
+message in the interpreter result.
+When searching a string for multiple matches of a pattern,
+it is important to distinguish between the start of the original
+string and the start of the current search.
+For example, when searching for the second occurrence of a
+match, the \fItext\fR argument might point to the character
+just after the first match;  however, it is important for the
+pattern matcher to know that this is not the start of the entire string,
+so that it does not allow
+.QW \fB^\fR
+atoms in the pattern to match.
+The \fIstart\fR argument provides this information by pointing
+to the start of the overall string containing \fItext\fR.
+\fIStart\fR will be less than or equal to \fItext\fR;  if it
+is less than \fItext\fR then no \fB^\fR matches will be allowed.
+.PP
+\fBTcl_RegExpRange\fR may be invoked after \fBTcl_RegExpExec\fR
+returns;  it provides detailed information about what ranges of
+the string matched what parts of the pattern.
+\fBTcl_RegExpRange\fR returns a pair of pointers in \fI*startPtr\fR
+and \fI*endPtr\fR that identify a range of characters in
+the source string for the most recent call to \fBTcl_RegExpExec\fR.
+\fIIndex\fR indicates which of several ranges is desired:
+if \fIindex\fR is 0, information is returned about the overall range
+of characters that matched the entire pattern;  otherwise,
+information is returned about the range of characters that matched the
+\fIindex\fR'th parenthesized subexpression within the pattern.
+If there is no range corresponding to \fIindex\fR then NULL
+is stored in \fI*startPtr\fR and \fI*endPtr\fR.
+.PP
+\fBTcl_GetRegExpFromObj\fR, \fBTcl_RegExpExecObj\fR, and
+\fBTcl_RegExpGetInfo\fR are value interfaces that provide the most
+direct control of Henry Spencer's regular expression library.  For
+users that need to modify compilation and execution options directly,
+it is recommended that you use these interfaces instead of calling the
+internal regexp functions.  These interfaces handle the details of UTF
+to Unicode translations as well as providing improved performance

+\fBTcl_GetRegExpFromObj\fR attempts to return a compiled regular
+expression from the \fIpatObj\fR.  If the value does not already
+contain a compiled regular expression it will attempt to create one
+from the string in the value and assign it to the internal
+representation of the \fIpatObj\fR.  The return value of this function
+is of type \fBTcl_RegExp\fR.  The return value is a token for this
+compiled form, which can be used in subsequent calls to
+\fBTcl_RegExpExecObj\fR or \fBTcl_RegExpGetInfo\fR.  If an error
+occurs while compiling the regular expression then
+\fBTcl_GetRegExpFromObj\fR returns NULL and leaves an error message in
+the interpreter result.  The regular expression token can be used as
+long as the internal representation of \fIpatObj\fR refers to the
+compiled form.  The \fIcflags\fR argument is a bit-wise OR of
+zero or more of the following flags that control the compilation of
+\fIpatObj\fR:
+.RS 2
+.TP
+\fBTCL_REG_ADVANCED\fR
+Compile advanced regular expressions
+.PQ ARE s .
+This mode corresponds to

+specified.
+.TP
+\fBTCL_REG_EXPANDED\fR
+Compile the regular expression (basic, extended, or advanced) using an

+\fBTCL_REG_NOCASE\fR
+Compile for matching that ignores upper/lower case distinctions.

+\fBTCL_REG_NEWLINE\fR

+\fBTcl_RegExpExecObj\fR executes the regular expression pattern
+matcher.  It returns 1 if \fIobjPtr\fR contains a range of characters
+that match \fIregexp\fR, 0 if no match is found, and \-1 if an error
+occurs.  In the case of an error, \fBTcl_RegExpExecObj\fR leaves an
+error message in the interpreter result.  The \fInmatches\fR value
+indicates to the matcher how many subexpressions are of interest.  If
+\fInmatches\fR is 0, then no subexpression match information is
+recorded, which may allow the matcher to make various optimizations.
+If the value is \-1, then all of the subexpressions in the pattern are
+remembered.  If the value is a positive integer, then only that number
+of subexpressions will be remembered.  Matching begins at the
+specified Unicode character index given by \fIoffset\fR.  Unlike
+\fBTcl_RegExpExec\fR, the behavior of anchors is not affected by the
+offset value.  Instead the behavior of the anchors is explicitly
+controlled by the \fIeflags\fR argument, which is a bit-wise OR of
+zero or more of the following flags:
+.RS 2
+.TP
+\fBTCL_REG_NOTBOL\fR
+The starting character will not be treated as the beginning of a
+line or the beginning of the string, so

+.QW \fB\eA\fR
+matches.
+.TP
+\fBTCL_REG_NOTEOL\fR
+The last character in the string will not be treated as the end of a

+.RE
+.PP
+\fBTcl_RegExpGetInfo\fR retrieves information about the last match
+performed with a given regular expression \fIregexp\fR.  The
+\fIinfoPtr\fR argument contains a pointer to a structure that is
+defined as follows:
+.PP
+.CS
+typedef struct Tcl_RegExpInfo {
+    int \fInsubs\fR;
+    Tcl_RegExpIndices *\fImatches\fR;
+    long \fIextendStart\fR;
+} \fBTcl_RegExpInfo\fR;
+.CE
+.PP
+The \fInsubs\fR field contains a count of the number of parenthesized
+subexpressions within the regular expression.  If the \fBTCL_REG_NOSUB\fR
+was used, then this value will be zero.  The \fImatches\fR field
+points to an array of \fInsubs\fR+1 values that indicate the bounds of each
+subexpression matched.  The first element in the array refers to the
+range matched by the entire regular expression, and subsequent elements
+refer to the parenthesized subexpressions in the order that they
+appear in the pattern.  Each element is a structure that is defined as
+follows:
+.PP
+.CS
+typedef struct Tcl_RegExpIndices {
+    long \fIstart\fR;
+    long \fIend\fR;
+} \fBTcl_RegExpIndices\fR;
+.CE
+.PP
+The \fIstart\fR and \fIend\fR values are Unicode character indices
+relative to the offset location within \fIobjPtr\fR where matching began.
+The \fIstart\fR index identifies the first character of the matched
+subexpression.  The \fIend\fR index identifies the first character
+after the matched subexpression.  If the subexpression matched the
+empty string, then \fIstart\fR and \fIend\fR will be equal.  If the
+subexpression did not participate in the match, then \fIstart\fR and
+\fIend\fR will be set to \-1.
+.PP
+The \fIextendStart\fR field in \fBTcl_RegExpInfo\fR is only set if the
+\fBTCL_REG_CANMATCH\fR flag was used.  It indicates the first
+character in the string where a match could occur.  If a match was
+found, this will be the same as the beginning of the current match.
+If no match was found, then it indicates the earliest point at which a
+match might occur if additional text is appended to the string.  If it
+is no match is possible even with further text, this field will be set 
+to \-1.

+.BE
+.SH DESCRIPTION
+.PP
+These routines allows a C procedure to take a snapshot of the current
+state of an interpreter so that it can be restored after a call
+to \fBTcl_Eval\fR or some other routine that modifies the interpreter
+state.  There are two triplets of routines meant to work together.
+.PP
+The first triplet stores the snapshot of interpreter state in
+an opaque token returned by \fBTcl_SaveInterpState\fR.  That token
+value may then be passed back to one of \fBTcl_RestoreInterpState\fR
+or \fBTcl_DiscardInterpState\fR, depending on whether the interp
+state is to be restored.  So long as one of the latter two routines
+is called, Tcl will take care of memory management.
+.PP
+The second triplet stores the snapshot of only the interpreter
+result (not its complete state) in memory allocated by the caller.
+These routines are passed a pointer to a \fBTcl_SavedResult\fR structure
+that is used to store enough information to restore the interpreter result.
+This structure can be allocated on the stack of the calling
+procedure.  These routines do not save the state of any error
+information in the interpreter (e.g. the \fB\-errorcode\fR or
+\fB\-errorinfo\fR return options, when an error is in progress).
+.PP
+Because the routines \fBTcl_SaveInterpState\fR,
+\fBTcl_RestoreInterpState\fR, and \fBTcl_DiscardInterpState\fR perform
+a superset of the functions provided by the other routines,
+any new code should only make use of the more powerful routines.
+The older, weaker routines \fBTcl_SaveResult\fR, \fBTcl_RestoreResult\fR,
+and \fBTcl_DiscardResult\fR continue to exist only for the sake
+of existing programs that may already be using them.  
+.PP
+\fBTcl_SaveInterpState\fR takes a snapshot of those portions of
+interpreter state that make up the full result of script evaluation.
+This include the interpreter result, the return code (passed in
+as the \fIstatus\fR argument, and any return options, including
+\fB\-errorinfo\fR and \fB\-errorcode\fR when an error is in progress.
+This snapshot is returned as an opaque token of type \fBTcl_InterpState\fR.
+The call to \fBTcl_SaveInterpState\fR does not itself change the
+state of the interpreter.  Unlike \fBTcl_SaveResult\fR, it does
+not reset the interpreter.
+.PP
+\fBTcl_RestoreInterpState\fR accepts a \fBTcl_InterpState\fR token
+previously returned by \fBTcl_SaveInterpState\fR and restores the
+state of the interp to the state held in that snapshot.  The return
+value of \fBTcl_RestoreInterpState\fR is the status value originally
+passed to \fBTcl_SaveInterpState\fR when the snapshot token was
+created.
+.PP
+\fBTcl_DiscardInterpState\fR is called to release a \fBTcl_InterpState\fR
+token previously returned by \fBTcl_SaveInterpState\fR when that
+snapshot is not to be restored to an interp.
+.PP
+The \fBTcl_InterpState\fR token returned by \fBTcl_SaveInterpState\fR
+must eventually be passed to either \fBTcl_RestoreInterpState\fR
+or \fBTcl_DiscardInterpState\fR to avoid a memory leak.  Once
+the \fBTcl_InterpState\fR token is passed to one of them, the
+token is no longer valid and should not be used anymore.
+.PP
+\fBTcl_SaveResult\fR moves the string and value results
+of \fIinterp\fR into the location specified by \fIstatePtr\fR.
+\fBTcl_SaveResult\fR clears the result for \fIinterp\fR and
+leaves the result in its normal empty initialized state.
+.PP
+\fBTcl_RestoreResult\fR moves the string and value results from
+\fIstatePtr\fR back into \fIinterp\fR.  Any result or error that was
+already in the interpreter will be cleared.  The \fIstatePtr\fR is left
+in an uninitialized state and cannot be used until another call to
+\fBTcl_SaveResult\fR.
+.PP
+\fBTcl_DiscardResult\fR releases the saved interpreter state
+stored at \fBstatePtr\fR.  The state structure is left in an
+uninitialized state and cannot be used until another call to
+\fBTcl_SaveResult\fR.
+.PP
+Once \fBTcl_SaveResult\fR is called to save the interpreter
+result, either \fBTcl_RestoreResult\fR or
+\fBTcl_DiscardResult\fR must be called to properly clean up the
+memory associated with the saved state.

+.BE
+.SH DESCRIPTION
+.PP
+The current definition of a Tcl channel driver does not permit the direct
+return of arbitrary error messages, except for the setting and retrieval of
+channel options. All other functions are restricted to POSIX error codes.
+.PP
+The functions described here overcome this limitation. Channel drivers are
+allowed to use \fBTcl_SetChannelError\fR and \fBTcl_SetChannelErrorInterp\fR
+to place arbitrary error messages in \fBbypass areas\fR defined for channels
+and interpreters. And the generic I/O layer uses \fBTcl_GetChannelError\fR and
+\fBTcl_GetChannelErrorInterp\fR to look for messages in the bypass areas and
+arrange for their return as errors. The POSIX error codes set by a driver are
+used now if and only if no messages are present.
+.PP
+\fBTcl_SetChannelError\fR stores error information in the bypass area of the
+specified channel. The number of references to the \fBmsg\fR value goes up by
+one. Previously stored information will be discarded, by releasing the
+reference held by the channel. The channel reference must not be NULL.
+.PP
+\fBTcl_SetChannelErrorInterp\fR stores error information in the bypass area of
+the specified interpreter. The number of references to the \fBmsg\fR value
+goes up by one. Previously stored information will be discarded, by releasing
+the reference held by the interpreter. The interpreter reference must not be
+NULL.
+.PP
+\fBTcl_GetChannelError\fR places either the error message held in the bypass
+area of the specified channel into \fImsgPtr\fR, or NULL; and resets the
+bypass, that is, after an invocation all following invocations will return
+NULL, until an intervening invocation of \fBTcl_SetChannelError\fR with a
+non-NULL message. The \fImsgPtr\fR must not be NULL. The reference count of
+the message is not touched.  The reference previously held by the channel is
+now held by the caller of the function and it is its responsibility to release
+that reference when it is done with the value.
+.PP
+\fBTcl_GetChannelErrorInterp\fR places either the error message held in the
+bypass area of the specified interpreter into \fImsgPtr\fR, or NULL; and
+resets the bypass, that is, after an invocation all following invocations will
+return NULL, until an intervening invocation of
+\fBTcl_SetChannelErrorInterp\fR with a non-NULL message. The \fImsgPtr\fR must
+not be NULL. The reference count of the message is not touched.  The reference
+previously held by the interpreter is now held by the caller of the function
+and it is its responsibility to release that reference when it is done with
+the value.
+.PP
+Which functions of a channel driver are allowed to use which bypass function
+is listed below, as is which functions of the public channel API may leave a
+messages in the bypass areas.
+.IP \fBTcl_DriverCloseProc\fR
+May use \fBTcl_SetChannelErrorInterp\fR, and only this function.
+.IP \fBTcl_DriverInputProc\fR
+May use \fBTcl_SetChannelError\fR, and only this function.
+.IP \fBTcl_DriverOutputProc\fR

+May use \fBTcl_SetChannelError\fR, and only this function.
+.IP \fBTcl_DriverWideSeekProc\fR
+May use \fBTcl_SetChannelError\fR, and only this function.
+.IP \fBTcl_DriverSetOptionProc\fR
+Has already the ability to pass arbitrary error messages. Must \fInot\fR use
+any of the new functions.
+.IP \fBTcl_DriverGetOptionProc\fR
+Has already the ability to pass arbitrary error messages. Must
+\fInot\fR use any of the new functions.
+.IP \fBTcl_DriverWatchProc\fR
+Must \fInot\fR use any of the new functions. Is internally called and has no
+ability to return any type of error whatsoever.
+.IP \fBTcl_DriverBlockModeProc\fR
+May use \fBTcl_SetChannelError\fR, and only this function.
+.IP \fBTcl_DriverGetHandleProc\fR
+Must \fInot\fR use any of the new functions. It is only a low-level function,
+and not used by Tcl commands.
+.IP \fBTcl_DriverHandlerProc\fR
+Must \fInot\fR use any of the new functions. Is internally called and has no
+ability to return any type of error whatsoever.
+.PP
+Given the information above the following public functions of the Tcl C API
+are affected by these changes; when these functions are called, the channel
+may now contain a stored arbitrary error message requiring processing by the
+caller.

+.SH DESCRIPTION
+.PP
+At any given time Tcl enforces a limit on the number of recursive

+such as \fBTcl_GlobalEval\fR.
+Any call to \fBTcl_Eval\fR that exceeds this depth is aborted with

+.PP
+\fBTcl_SetRecursionLimit\fR may be used to change the maximum

+.SH DESCRIPTION
+.PP
+The procedures described here are utilities for manipulating the
+result value in a Tcl interpreter.
+The interpreter result may be either a Tcl value or a string.
+For example, \fBTcl_SetObjResult\fR and \fBTcl_SetResult\fR
+set the interpreter result to, respectively, a value and a string.
+Similarly, \fBTcl_GetObjResult\fR and \fBTcl_GetStringResult\fR
+return the interpreter result as a value and as a string.
+The procedures always keep the string and value forms
+of the interpreter result consistent.
+For example, if \fBTcl_SetObjResult\fR is called to set
+the result to a value,
+then \fBTcl_GetStringResult\fR is called,
+it will return the value's string representation.
+.PP
+\fBTcl_SetObjResult\fR
+arranges for \fIobjPtr\fR to be the result for \fIinterp\fR,
+replacing any existing result.
+The result is left pointing to the value
+referenced by \fIobjPtr\fR.
+\fIobjPtr\fR's reference count is incremented
+since there is now a new reference to it from \fIinterp\fR.
+The reference count for any old result value
+is decremented and the old result value is freed if no
+references to it remain.
+.PP
+\fBTcl_GetObjResult\fR returns the result for \fIinterp\fR as a value.
+The value's reference count is not incremented;
+if the caller needs to retain a long-term pointer to the value
+they should use \fBTcl_IncrRefCount\fR to increment its reference count
+in order to keep it from being freed too early or accidentally changed.
+.PP
+\fBTcl_SetResult\fR
+arranges for \fIresult\fR to be the result for the current Tcl
+command in \fIinterp\fR, replacing any existing result.
+The \fIfreeProc\fR argument specifies how to manage the storage
+for the \fIresult\fR argument;
+it is discussed in the section
+\fBTHE TCL_FREEPROC ARGUMENT TO TCL_SETRESULT\fR below.
+If \fIresult\fR is \fBNULL\fR, then \fIfreeProc\fR is ignored
+and \fBTcl_SetResult\fR
+re-initializes \fIinterp\fR's result to point to an empty string.
+.PP
+\fBTcl_GetStringResult\fR returns the result for \fIinterp\fR as a string.
+If the result was set to a value by a \fBTcl_SetObjResult\fR call,
+the value form will be converted to a string and returned.
+If the value's string representation contains null bytes,
+this conversion will lose information.
+For this reason, programmers are encouraged to
+write their code to use the new value API procedures
+and to call \fBTcl_GetObjResult\fR instead.
+.PP
+\fBTcl_ResetResult\fR clears the result for \fIinterp\fR
+and leaves the result in its normal empty initialized state.
+If the result is a value,
+its reference count is decremented and the result is left
+pointing to an unshared value representing an empty string.
+If the result is a dynamically allocated string, its memory is free*d
+and the result is left as a empty string.
+\fBTcl_ResetResult\fR also clears the error state managed by
+\fBTcl_AddErrorInfo\fR, \fBTcl_AddObjErrorInfo\fR,
+and \fBTcl_SetErrorCode\fR.
+.PP
+\fBTcl_AppendResult\fR makes it easy to build up Tcl results in pieces.
+It takes each of its \fIresult\fR arguments and appends them in order
+to the current result associated with \fIinterp\fR.
+If the result is in its initialized empty state (e.g. a command procedure
+was just invoked or \fBTcl_ResetResult\fR was just called),
+then \fBTcl_AppendResult\fR sets the result to the concatenation of
+its \fIresult\fR arguments.
+\fBTcl_AppendResult\fR may be called repeatedly as additional pieces
+of the result are produced.
+\fBTcl_AppendResult\fR takes care of all the
+storage management issues associated with managing \fIinterp\fR's
+result, such as allocating a larger result area if necessary.
+It also manages conversion to and from the \fIresult\fR field of the
+\fIinterp\fR so as to handle backward-compatibility with old-style
+extensions.
+Any number of \fIresult\fR arguments may be passed in a single
+call; the last argument in the list must be a NULL pointer.
+.PP
+\fBTcl_AppendResultVA\fR is the same as \fBTcl_AppendResult\fR except that
+instead of taking a variable number of arguments it takes an argument list.
+.PP
+.VS 8.6
+\fBTcl_TransferResult\fR moves a result from one interpreter to another,
+optionally (dependent on the \fIresult\fR parameter) including the error
+information dictionary as well. The interpreters must be in the same thread.
+The source interpreter will have its result reset by this operation.
+.VE 8.6
+.SH "DEPRECATED INTERFACES"
+.SS "OLD STRING PROCEDURES"
+.PP
+Use of the following procedures (is deprecated
+since they manipulate the Tcl result as a string.
+Procedures such as \fBTcl_SetObjResult\fR
+that manipulate the result as a value
+can be significantly more efficient.
+.PP
+\fBTcl_AppendElement\fR is similar to \fBTcl_AppendResult\fR in
+that it allows results to be built up in pieces.
+However, \fBTcl_AppendElement\fR takes only a single \fIelement\fR
+argument and it appends that argument to the current result
+as a proper Tcl list element.
+\fBTcl_AppendElement\fR adds backslashes or braces if necessary
+to ensure that \fIinterp\fR's result can be parsed as a list and that
+\fIelement\fR will be extracted as a single element.
+Under normal conditions, \fBTcl_AppendElement\fR will add a space
+character to \fIinterp\fR's result just before adding the new
+list element, so that the list elements in the result are properly
+separated.
+However if the new list element is the first in a list or sub-list
+(i.e. \fIinterp\fR's current result is empty, or consists of the
+single character
+.QW { ,
+or ends in the characters
+.QW " {" )
+then no space is added.
+.PP
+\fBTcl_FreeResult\fR performs part of the work
+of \fBTcl_ResetResult\fR.
+It frees up the memory associated with \fIinterp\fR's result.
+It also sets \fIinterp->freeProc\fR to zero, but does not
+change \fIinterp->result\fR or clear error state.
+\fBTcl_FreeResult\fR is most commonly used when a procedure
+is about to replace one result value with another.
+.SS "DIRECT ACCESS TO INTERP->RESULT"
+.PP
+It used to be legal for programs to
+directly read and write \fIinterp->result\fR
+to manipulate the interpreter result.  The Tcl headers no longer
+permit this access by default, and C code still doing this must
+be updated to use supported routines \fBTcl_GetObjResult\fR,
+\fBTcl_GetStringResult\fR, \fBTcl_SetObjResult\fR, and \fBTcl_SetResult\fR.
+As a migration aid, access can be restored with the compiler directive
+.CS
+#define USE_INTERP_RESULT
+.CE
+but this is meant only to offer life support to otherwise dead code.
+.SH "THE TCL_FREEPROC ARGUMENT TO TCL_SETRESULT"
+.PP
+\fBTcl_SetResult\fR's \fIfreeProc\fR argument specifies how 
+the Tcl system is to manage the storage for the \fIresult\fR argument.
+If \fBTcl_SetResult\fR or \fBTcl_SetObjResult\fR are called
+at a time when \fIinterp\fR holds a string result,
+they do whatever is necessary to dispose of the old string result
+(see the \fBTcl_Interp\fR manual entry for details on this).
+.PP
+If \fIfreeProc\fR is \fBTCL_STATIC\fR it means that \fIresult\fR
+refers to an area of static storage that is guaranteed not to be
+modified until at least the next call to \fBTcl_Eval\fR.
+If \fIfreeProc\fR
+is \fBTCL_DYNAMIC\fR it means that \fIresult\fR was allocated with a call
+to \fBTcl_Alloc\fR and is now the property of the Tcl system.
+\fBTcl_SetResult\fR will arrange for the string's storage to be
+released by calling \fBTcl_Free\fR when it is no longer needed.
+If \fIfreeProc\fR is \fBTCL_VOLATILE\fR it means that \fIresult\fR
+points to an area of memory that is likely to be overwritten when
+\fBTcl_SetResult\fR returns (e.g. it points to something in a stack frame).
+In this case \fBTcl_SetResult\fR will make a copy of the string in
+dynamically allocated storage and arrange for the copy to be the
+result for the current Tcl command.
+.PP
+If \fIfreeProc\fR is not one of the values \fBTCL_STATIC\fR,
+\fBTCL_DYNAMIC\fR, and \fBTCL_VOLATILE\fR, then it is the address
+of a procedure that Tcl should call to free the string.
+This allows applications to use non-standard storage allocators.
+When Tcl no longer needs the storage for the string, it will
+call \fIfreeProc\fR. \fIFreeProc\fR should have arguments and
+result that match the type \fBTcl_FreeProc\fR:
+.PP
+.CS
+typedef void \fBTcl_FreeProc\fR(
+        char *\fIblockPtr\fR);
+.CE
+.PP
+When \fIfreeProc\fR is called, its \fIblockPtr\fR will be set to
+the value of \fIresult\fR passed to \fBTcl_SetResult\fR.

+.SH DESCRIPTION
+.PP
+These procedures are used to create, modify, read, and delete
+Tcl variables from C code.
+.PP
+\fBTcl_SetVar2Ex\fR, \fBTcl_SetVar\fR, \fBTcl_SetVar2\fR, and
+\fBTcl_ObjSetVar2\fR 
+will create a new variable or modify an existing one.
+These procedures set the given variable to the value
+given by \fInewValuePtr\fR or \fInewValue\fR and return a
+pointer to the variable's new value, which is stored in Tcl's
+variable structure.
+\fBTcl_SetVar2Ex\fR and \fBTcl_ObjSetVar2\fR take the new value as a
+Tcl_Obj and return
+a pointer to a Tcl_Obj.  \fBTcl_SetVar\fR and \fBTcl_SetVar2\fR
+take the new value as a string and return a string; they are
+usually less efficient than \fBTcl_ObjSetVar2\fR.  Note that the
+return value may be different than the \fInewValuePtr\fR or
+\fInewValue\fR argument, due to modifications made by write traces.
+If an error occurs in setting the variable (e.g. an array
+variable is referenced without giving an index into the array)
+NULL is returned and an error message is left in \fIinterp\fR's
+result if the \fBTCL_LEAVE_ERR_MSG\fR \fIflag\fR bit is set.
+.PP
+\fBTcl_GetVar2Ex\fR, \fBTcl_GetVar\fR, \fBTcl_GetVar2\fR, and
+\fBTcl_ObjGetVar2\fR
+return the current value of a variable.
+The arguments to these procedures are treated in the same way
+as the arguments to the procedures described above.
+Under normal circumstances, the return value is a pointer
+to the variable's value.  For \fBTcl_GetVar2Ex\fR and
+\fBTcl_ObjGetVar2\fR the value is
+returned as a pointer to a Tcl_Obj.  For \fBTcl_GetVar\fR and
+\fBTcl_GetVar2\fR the value is returned as a string; this is
+usually less efficient, so \fBTcl_GetVar2Ex\fR or \fBTcl_ObjGetVar2\fR
+are preferred.
+If an error occurs while reading the variable (e.g. the variable
+does not exist or an array element is specified for a scalar
+variable), then NULL is returned and an error message is left
+in \fIinterp\fR's result if the \fBTCL_LEAVE_ERR_MSG\fR \fIflag\fR
+bit is set.
+.PP
+\fBTcl_UnsetVar\fR and \fBTcl_UnsetVar2\fR may be used to remove
+a variable, so that future attempts to read the variable will return
+an error.
+The arguments to these procedures are treated in the same way
+as the arguments to the procedures above.
+If the variable is successfully removed then \fBTCL_OK\fR is returned.
+If the variable cannot be removed because it does not exist then
+\fBTCL_ERROR\fR is returned and an error message is left
+in \fIinterp\fR's result if the \fBTCL_LEAVE_ERR_MSG\fR \fIflag\fR
+bit is set.
+If an array element is specified, the given element is removed
+but the array remains.
+If an array name is specified without an index, then the entire
+array is removed.
+.PP
+The name of a variable may be specified to these procedures in
+four ways:
+.IP [1]
+If \fBTcl_SetVar\fR, \fBTcl_GetVar\fR, or \fBTcl_UnsetVar\fR
+is invoked, the variable name is given as
+a single string, \fIvarName\fR.
+If \fIvarName\fR contains an open parenthesis and ends with a
+close parenthesis, then the value between the parentheses is
+treated as an index (which can have any string value) and
+the characters before the first open
+parenthesis are treated as the name of an array variable.
+If \fIvarName\fR does not have parentheses as described above, then
+the entire string is treated as the name of a scalar variable.
+.IP [2]
+If the \fIname1\fR and \fIname2\fR arguments are provided and
+\fIname2\fR is non-NULL, then an array element is specified and
+the array name and index have
+already been separated by the caller: \fIname1\fR contains the
+name and \fIname2\fR contains the index.  An error is generated
+if \fIname1\fR  contains an open parenthesis and ends with a
+close parenthesis (array element) and \fIname2\fR is non-NULL.
+.IP [3]
+If \fIname2\fR is NULL, \fIname1\fR is treated just like
+\fIvarName\fR in case [1] above (it can be either a scalar or an array
+element variable name).
+.PP
+The \fIflags\fR argument may be used to specify any of several
+options to the procedures.
+It consists of an OR-ed combination of the following bits.
+.TP
+\fBTCL_GLOBAL_ONLY\fR
+Under normal circumstances the procedures look up variables as follows.
+If a procedure call is active in \fIinterp\fR,
+the variable is looked up at the current level of procedure call.
+Otherwise, the variable is looked up first in the current namespace,
+then in the global namespace.
+However, if this bit is set in \fIflags\fR then the variable
+is looked up only in the global namespace
+even if there is a procedure call active.
+If both \fBTCL_GLOBAL_ONLY\fR and \fBTCL_NAMESPACE_ONLY\fR are given,
+\fBTCL_GLOBAL_ONLY\fR is ignored.
+.TP
+\fBTCL_NAMESPACE_ONLY\fR
+If this bit is set in \fIflags\fR then the variable
+is looked up only in the current namespace; if a procedure is active
+its variables are ignored, and the global namespace is also ignored unless
+it is the current namespace.
+.TP
+\fBTCL_LEAVE_ERR_MSG\fR
+If an error is returned and this bit is set in \fIflags\fR, then
+an error message will be left in the interpreter's result,
+where it can be retrieved with \fBTcl_GetObjResult\fR
+or \fBTcl_GetStringResult\fR.
+If this flag bit is not set then no error message is left
+and the interpreter's result will not be modified.
+.TP
+\fBTCL_APPEND_VALUE\fR
+If this bit is set then \fInewValuePtr\fR or \fInewValue\fR is
+appended to the current value instead of replacing it.
+If the variable is currently undefined, then the bit is ignored.
+This bit is only used by the \fBTcl_Set*\fR procedures.
+.TP
+\fBTCL_LIST_ELEMENT\fR
+If this bit is set, then \fInewValue\fR is converted to a valid
+Tcl list element before setting (or appending to) the variable.
+A separator space is appended before the new list element unless
+the list element is going to be the first element in a list or
+sublist (i.e. the variable's current value is empty, or contains
+the single character
+.QW { ,
+or ends in
+.QW " }" ).
+When appending, the original value of the variable must also be
+a valid list, so that the operation is the appending of a new
+list element onto a list.
+.PP
+\fBTcl_GetVar\fR and \fBTcl_GetVar2\fR
+return the current value of a variable.
+The arguments to these procedures are treated in the same way
+as the arguments to \fBTcl_SetVar\fR and \fBTcl_SetVar2\fR.
+Under normal circumstances, the return value is a pointer
+to the variable's value (which is stored in Tcl's variable
+structure and will not change before the next call to \fBTcl_SetVar\fR
+or \fBTcl_SetVar2\fR).
+\fBTcl_GetVar\fR and \fBTcl_GetVar2\fR use the flag bits \fBTCL_GLOBAL_ONLY\fR
+and \fBTCL_LEAVE_ERR_MSG\fR, both of
+which have
+the same meaning as for \fBTcl_SetVar\fR.
+If an error occurs in reading the variable (e.g. the variable
+does not exist or an array element is specified for a scalar
+variable), then NULL is returned.
+.PP
+\fBTcl_UnsetVar\fR and \fBTcl_UnsetVar2\fR may be used to remove
+a variable, so that future calls to \fBTcl_GetVar\fR or \fBTcl_GetVar2\fR
+for the variable will return an error.
+The arguments to these procedures are treated in the same way
+as the arguments to \fBTcl_GetVar\fR and \fBTcl_GetVar2\fR.
+If the variable is successfully removed then \fBTCL_OK\fR is returned.
+If the variable cannot be removed because it does not exist then
+\fBTCL_ERROR\fR is returned.
+If an array element is specified, the given element is removed
+but the array remains.
+If an array name is specified without an index, then the entire
+array is removed.

+.BE
+.SH DESCRIPTION
+.PP
+These procedures may be used to disassemble and reassemble Tcl lists.
+\fBTcl_SplitList\fR breaks a list up into its constituent elements,
+returning an array of pointers to the elements using
+\fIargcPtr\fR and \fIargvPtr\fR.
+While extracting the arguments, \fBTcl_SplitList\fR obeys the usual
+rules for backslash substitutions and braces.  The area of
+memory pointed to by \fI*argvPtr\fR is dynamically allocated;  in
+addition to the array of pointers, it
+also holds copies of all the list elements.  It is the caller's
+responsibility to free up all of this storage.
+For example, suppose that you have called \fBTcl_SplitList\fR with
+the following code:
+.PP
+.CS
+int argc, code;
+char *string;
+char **argv;
+\&...
+code = \fBTcl_SplitList\fR(interp, string, &argc, &argv);
+.CE
+.PP
+Then you should eventually free the storage with a call like the
+following:
+.PP
+.CS
+Tcl_Free((char *) argv);
+.CE
+.PP
+\fBTcl_SplitList\fR normally returns \fBTCL_OK\fR, which means the list was
+successfully parsed.
+If there was a syntax error in \fIlist\fR, then \fBTCL_ERROR\fR is returned
+and the interpreter's result will point to an error message describing the
+problem (if \fIinterp\fR was not NULL).
+If \fBTCL_ERROR\fR is returned then no memory is allocated and \fI*argvPtr\fR
+is not modified.
+.PP
+\fBTcl_Merge\fR is the inverse of \fBTcl_SplitList\fR:  it
+takes a collection of strings given by \fIargc\fR
+and \fIargv\fR and generates a result string
+that has proper list structure.
+This means that commands like \fBindex\fR may be used to
+extract the original elements again.
+In addition, if the result of \fBTcl_Merge\fR is passed to \fBTcl_Eval\fR,
+it will be parsed into \fIargc\fR words whose values will
+be the same as the \fIargv\fR strings passed to \fBTcl_Merge\fR.
+\fBTcl_Merge\fR will modify the list elements with braces and/or
+backslashes in order to produce proper Tcl list structure.
+The result string is dynamically allocated
+using \fBTcl_Alloc\fR;  the caller must eventually release the space
+using \fBTcl_Free\fR.
+.PP
+If the result of \fBTcl_Merge\fR is passed to \fBTcl_SplitList\fR,
+the elements returned by \fBTcl_SplitList\fR will be identical to
+those passed into \fBTcl_Merge\fR.
+However, the converse is not true:  if \fBTcl_SplitList\fR
+is passed a given string, and the resulting \fIargc\fR and
+\fIargv\fR are passed to \fBTcl_Merge\fR, the resulting string
+may not be the same as the original string passed to \fBTcl_SplitList\fR.
+This is because \fBTcl_Merge\fR may use backslashes and braces
+differently than the original string.
+.PP
+\fBTcl_ScanElement\fR and \fBTcl_ConvertElement\fR are the
+procedures that do all of the real work of \fBTcl_Merge\fR.
+\fBTcl_ScanElement\fR scans its \fIsrc\fR argument
+and determines how to use backslashes and braces
+when converting it to a list element.
+It returns an overestimate of the number of characters
+required to represent \fIsrc\fR as a list element, and
+it stores information in \fI*flagsPtr\fR that is needed
+by \fBTcl_ConvertElement\fR.
+.PP
+\fBTcl_ConvertElement\fR is a companion procedure to \fBTcl_ScanElement\fR.
+It does the actual work of converting a string to a list element.
+Its \fIflags\fR argument must be the same as the value returned
+by \fBTcl_ScanElement\fR.
+\fBTcl_ConvertElement\fR writes a proper list element to memory
+starting at *\fIdst\fR and returns a count of the total number
+of characters written, which will be no more than the result
+returned by \fBTcl_ScanElement\fR.
+\fBTcl_ConvertElement\fR writes out only the actual list element
+without any leading or trailing spaces: it is up to the caller to
+include spaces between adjacent list elements.
+.PP
+\fBTcl_ConvertElement\fR uses one of two different approaches to
+handle the special characters in \fIsrc\fR.  Wherever possible, it
+handles special characters by surrounding the string with braces.
+This produces clean-looking output, but cannot be used in some situations,
+such as when \fIsrc\fR contains unmatched braces.
+In these situations, \fBTcl_ConvertElement\fR handles special
+characters by generating backslash sequences for them.
+The caller may insist on the second approach by OR-ing the
+flag value returned by \fBTcl_ScanElement\fR with
+\fBTCL_DONT_USE_BRACES\fR.
+Although this will produce an uglier result, it is useful in some
+special situations, such as when \fBTcl_ConvertElement\fR is being
+used to generate a portion of an argument for a Tcl command.
+In this case, surrounding \fIsrc\fR with curly braces would cause
+the command not to be parsed correctly.
+.PP
+By default, \fBTcl_ConvertElement\fR will use quoting in its output
+to be sure the first character of an element is not the hash
+character
+.PQ # .
+This is to be sure the first element of any list
+passed to \fBeval\fR is not mis-parsed as the beginning of a comment.
+When a list element is not the first element of a list, this quoting
+is not necessary.  When the caller can be sure that the element is
+not the first element of a list, it can disable quoting of the leading
+hash character by OR-ing the flag value returned by \fBTcl_ScanElement\fR
+with \fBTCL_DONT_QUOTE_HASH\fR.
+.PP
+\fBTcl_ScanCountedElement\fR and \fBTcl_ConvertCountedElement\fR are
+the same as \fBTcl_ScanElement\fR and \fBTcl_ConvertElement\fR, except
+the length of string \fIsrc\fR is specified by the \fIlength\fR
+argument, and the string may contain embedded nulls.

+These procedures have been superseded by the Tcl-value-aware procedures in

+These procedures may be used to disassemble and reassemble file
+paths in a platform independent manner: they provide C-level access to
+the same functionality as the \fBfile split\fR, \fBfile join\fR, and
+\fBfile pathtype\fR commands.
+.PP
+\fBTcl_SplitPath\fR breaks a path into its constituent elements,
+returning an array of pointers to the elements using \fIargcPtr\fR and
+\fIargvPtr\fR.  The area of memory pointed to by \fI*argvPtr\fR is

+.PP
+Then you should eventually free the storage with a call like the
+following:
+.PP
+.CS
+Tcl_Free((char *) argv);
+.CE
+.PP
+\fBTcl_JoinPath\fR is the inverse of \fBTcl_SplitPath\fR: it takes a
+collection of path elements given by \fIargc\fR and \fIargv\fR and
+generates a result string that is a properly constructed path. The
+result string is appended to \fIresultPtr\fR.  \fIResultPtr\fR must
+refer to an initialized \fBTcl_DString\fR.
+.PP
+If the result of \fBTcl_SplitPath\fR is passed to \fBTcl_JoinPath\fR,
+the result will refer to the same location, but may not be in the same
+form.  This is because \fBTcl_SplitPath\fR and \fBTcl_JoinPath\fR
+eliminate duplicate path separators and return a normalized form for
+each platform.
+.PP
+\fBTcl_GetPathType\fR returns the type of the specified \fIpath\fR,
+where \fBTcl_PathType\fR is one of \fBTCL_PATH_ABSOLUTE\fR,
+\fBTCL_PATH_RELATIVE\fR, or \fBTCL_PATH_VOLUME_RELATIVE\fR.  See the

+.SH NAME
+Tcl_StandardChannels \- How the Tcl library deals with the standard channels
+.BE
+
+.SH DESCRIPTION
+.PP
+This page explains the initialization and use of standard channels in
+the Tcl library.
+.PP
+The term \fIstandard channels\fR comes out of the Unix world and
+refers to the three channels automatically opened by the OS for
+each new application. They are \fBstdin\fR, \fBstdout\fR and
+\fBstderr\fR. The first is the standard input an application can read
+from, the other two refer to writable channels, one for regular
+output and the other for error messages.
+.PP
+Tcl generalizes this concept in a cross-platform way and
+exposes standard channels to the script level.
+.SS "APPLICATION PROGRAMMING INTERFACES"
+.PP
+The public API procedures dealing directly with standard channels are
+\fBTcl_GetStdChannel\fR and \fBTcl_SetStdChannel\fR. Additional public
+APIs to consider are \fBTcl_RegisterChannel\fR,
+\fBTcl_CreateChannel\fR and \fBTcl_GetChannel\fR.
+.SH "INITIALIZATION OF TCL STANDARD CHANNELS"
+.PP
+Standard channels are initialized by the Tcl library in three cases:
+when explicitly requested, when implicitly required before returning
+channel information, or when implicitly required during registration
+of a new channel.
+.PP
+These cases differ in how they handle unavailable platform- specific
+standard channels.  (A channel is not
+.QW available
+if it could not be
+successfully opened; for example, in a Tcl application run as a
+Windows NT service.)
+.TP
+1)
+A single standard channel is initialized when it is explicitly
+specified in a call to \fBTcl_SetStdChannel\fR.  The states of the
+other standard channels are unaffected.
+.RS
+.PP
+Missing platform-specific standard channels do not matter here. This
+approach is not available at the script level.
+.RE
+.TP
+2)
+All uninitialized standard channels are initialized to
+platform-specific default values:
+.RS
+.TP
+(a)
+when open channels are listed with \fBTcl_GetChannelNames\fR (or the
+\fBfile channels\fR script command), or
+.TP
+(b)
+when information about any standard channel is requested with a call
+to \fBTcl_GetStdChannel\fR, or with a call to \fBTcl_GetChannel\fR
+which specifies one of the standard names (\fBstdin\fR, \fBstdout\fR
+and \fBstderr\fR).
+.PP
+In case of missing platform-specific standard channels, the Tcl
+standard channels are considered as initialized and then immediately
+closed. This means that the first three Tcl channels then opened by
+the application are designated as the Tcl standard channels.
+.RE
+.TP
+3)
+All uninitialized standard channels are initialized to
+platform-specific default values when a user-requested channel is
+registered with \fBTcl_RegisterChannel\fR.
+.PP
+In case of unavailable platform-specific standard channels the channel
+whose creation caused the initialization of the Tcl standard channels
+is made a normal channel.  The next three Tcl channels opened by the
+application are designated as the Tcl standard channels.  In other
+words, of the first four Tcl channels opened by the application the
+second to fourth are designated as the Tcl standard channels.
+.SH "RE-INITIALIZATION OF TCL STANDARD CHANNELS"
+.PP
+Once a Tcl standard channel is initialized through one of the methods
+above, closing this Tcl standard channel will cause the next call to
+\fBTcl_CreateChannel\fR to make the new channel the new standard
+channel, too. If more than one Tcl standard channel was closed
+\fBTcl_CreateChannel\fR will fill the empty slots in the order
+\fBstdin\fR, \fBstdout\fR and \fBstderr\fR.
+.PP
+\fBTcl_CreateChannel\fR will not try to reinitialize an empty slot if
+that slot was not initialized before. It is this behavior which
+enables an application to employ method 1 of initialization, i.e. to
+create and designate their own Tcl standard channels.
+.SH "SHELL-SPECIFIC DETAILS"
+.SS tclsh
+.PP
+The Tcl shell (or rather the function \fBTcl_Main\fR, which forms the
+core of the shell's implementation) uses method 2 to initialize
+the standard channels.
+.SS wish
+.PP
+The windowing shell (or rather the function \fBTk_MainEx\fR, which
+forms the core of the shell's implementation) uses method 1 to
+initialize the standard channels (See \fBTk_InitConsoleChannels\fR)
+on non-Unix platforms.  On Unix platforms, \fBTk_MainEx\fR implicitly
+uses method 2 to initialize the standard channels.

+.SH DESCRIPTION
+.PP
+The procedures described in this manual entry allow Tcl values to
+be manipulated as string values.  They use the internal representation
+of the value to store additional information to make the string
+manipulations more efficient.  In particular, they make a series of
+append operations efficient by allocating extra storage space for the
+string so that it does not have to be copied for each append.
+Also, indexing and length computations are optimized because the
+Unicode string representation is calculated and cached as needed.
+When using the \fBTcl_Append*\fR family of functions where the
+interpreter's result is the value being appended to, it is important
+to call Tcl_ResetResult first to ensure you are not unintentionally
+appending to existing data in the result value.
+.PP
+\fBTcl_NewStringObj\fR and \fBTcl_SetStringObj\fR create a new value
+or modify an existing value to hold a copy of the string given by
+\fIbytes\fR and \fIlength\fR.  \fBTcl_NewUnicodeObj\fR and
+\fBTcl_SetUnicodeObj\fR create a new value or modify an existing
+value to hold a copy of the Unicode string given by \fIunicode\fR and
+\fInumChars\fR.  \fBTcl_NewStringObj\fR and \fBTcl_NewUnicodeObj\fR
+return a pointer to a newly created value with reference count zero.
+All four procedures set the value to hold a copy of the specified
+string.  \fBTcl_SetStringObj\fR and \fBTcl_SetUnicodeObj\fR free any
+old string representation as well as any old internal representation
+of the value.
+.PP
+\fBTcl_GetStringFromObj\fR and \fBTcl_GetString\fR return a value's
+string representation.  This is given by the returned byte pointer and
+(for \fBTcl_GetStringFromObj\fR) length, which is stored in
+\fIlengthPtr\fR if it is non-NULL.  If the value's UTF string
+representation is invalid (its byte pointer is NULL), the string
+representation is regenerated from the value's internal
+representation.  The storage referenced by the returned byte pointer
+is owned by the value manager.  It is passed back as a writable
+pointer so that extension author creating their own \fBTcl_ObjType\fR
+will be able to modify the string representation within the
+\fBTcl_UpdateStringProc\fR of their \fBTcl_ObjType\fR.  Except for that
+limited purpose, the pointer returned by \fBTcl_GetStringFromObj\fR
+or \fBTcl_GetString\fR should be treated as read-only.  It is
+recommended that this pointer be assigned to a (const char *) variable.
+Even in the limited situations where writing to this pointer is
+acceptable, one should take care to respect the copy-on-write
+semantics required by \fBTcl_Obj\fR's, with appropriate calls
+to \fBTcl_IsShared\fR and \fBTcl_DuplicateObj\fR prior to any
+in-place modification of the string representation.
+The procedure \fBTcl_GetString\fR is used in the common case
+where the caller does not need the length of the string
+representation.
+.PP
+\fBTcl_GetUnicodeFromObj\fR and \fBTcl_GetUnicode\fR return a value's
+value as a Unicode string.  This is given by the returned pointer and
+(for \fBTcl_GetUnicodeFromObj\fR) length, which is stored in
+\fIlengthPtr\fR if it is non-NULL.  The storage referenced by the returned
+byte pointer is owned by the value manager and should not be modified by
+the caller.  The procedure \fBTcl_GetUnicode\fR is used in the common case
+where the caller does not need the length of the unicode string
+representation.
+.PP
+\fBTcl_GetUniChar\fR returns the \fIindex\fR'th character in the
+value's Unicode representation.
+.PP
+\fBTcl_GetRange\fR returns a newly created value comprised of the
+characters between \fIfirst\fR and \fIlast\fR (inclusive) in the
+value's Unicode representation.  If the value's Unicode
+representation is invalid, the Unicode representation is regenerated
+from the value's string representation.
+.PP
+\fBTcl_GetCharLength\fR returns the number of characters (as opposed
+to bytes) in the string value.
+.PP
+\fBTcl_AppendToObj\fR appends the data given by \fIbytes\fR and
+\fIlength\fR to the string representation of the value specified by
+\fIobjPtr\fR.  If the value has an invalid string representation,
+then an attempt is made to convert \fIbytes\fR is to the Unicode
+format.  If the conversion is successful, then the converted form of
+\fIbytes\fR is appended to the value's Unicode representation.
+Otherwise, the value's Unicode representation is invalidated and
+converted to the UTF format, and \fIbytes\fR is appended to the
+value's new string representation.
+.PP
+\fBTcl_AppendUnicodeToObj\fR appends the Unicode string given by
+\fIunicode\fR and \fInumChars\fR to the value specified by
+\fIobjPtr\fR.  If the value has an invalid Unicode representation,
+then \fIunicode\fR is converted to the UTF format and appended to the
+value's string representation.  Appends are optimized to handle
+repeated appends relatively efficiently (it over-allocates the string
+or Unicode space to avoid repeated reallocations and copies of
+value's string value).
+.PP
+\fBTcl_AppendObjToObj\fR is similar to \fBTcl_AppendToObj\fR, but it
+appends the string or Unicode value (whichever exists and is best
+suited to be appended to \fIobjPtr\fR) of \fIappendObjPtr\fR to
+\fIobjPtr\fR.
+.PP
+\fBTcl_AppendStringsToObj\fR is similar to \fBTcl_AppendToObj\fR
+except that it can be passed more than one value to append and
+each value must be a null-terminated string (i.e. none of the
+values may contain internal null characters).  Any number of
+\fIstring\fR arguments may be provided, but the last argument
+must be a NULL pointer to indicate the end of the list.
+.PP
+\fBTcl_AppendStringsToObjVA\fR is the same as \fBTcl_AppendStringsToObj\fR
+except that instead of taking a variable number of arguments it takes an
+argument list.
+.PP
+\fBTcl_AppendLimitedToObj\fR is similar to \fBTcl_AppendToObj\fR
+except that it imposes a limit on how many bytes are appended.
+This can be handy when the string to be appended might be
+very large, but the value being constructed should not be allowed to grow
+without bound. A common usage is when constructing an error message, where the
+end result should be kept short enough to be read.
+Bytes from \fIbytes\fR are appended to \fIobjPtr\fR, but no more
+than \fIlimit\fR bytes total are to be appended. If the limit prevents
+all \fIlength\fR bytes that are available from being appended, then the
+appending is done so that the last bytes appended are from the
+string \fIellipsis\fR. This allows for an indication of the truncation
+to be left in the string.
+When \fIlength\fR is \fB-1\fR, all bytes up to the first zero byte are appended,
+subject to the limit. When \fIellipsis\fR is NULL, the default
+string \fB...\fR is used. When \fIellipsis\fR is non-NULL, it must point
+to a zero-byte-terminated string in Tcl's internal UTF encoding.
+The number of bytes appended can be less than the lesser
+of \fIlength\fR and \fIlimit\fR when appending fewer
+bytes is necessary to append only whole multi-byte characters.
+.PP
+\fBTcl_Format\fR is the C-level interface to the engine of the \fBformat\fR
+command.  The actual command procedure for \fBformat\fR is little more
+than
+.PP
+.CS
+\fBTcl_Format\fR(interp, \fBTcl_GetString\fR(objv[1]), objc-2, objv+2);
+.CE
+.PP
+The \fIobjc\fR Tcl_Obj values in \fIobjv\fR are formatted into a string
+according to the conversion specification in \fIformat\fR argument, following
+the documentation for the \fBformat\fR command.  The resulting formatted
+string is converted to a new Tcl_Obj with refcount of zero and returned.
+If some error happens during production of the formatted string, NULL is
+returned, and an error message is recorded in \fIinterp\fR, if \fIinterp\fR
+is non-NULL.
+.PP
+\fBTcl_AppendFormatToObj\fR is an appending alternative form
+of \fBTcl_Format\fR with functionality equivalent to:
+.PP
+.CS
+Tcl_Obj *newPtr = \fBTcl_Format\fR(interp, format, objc, objv);
+if (newPtr == NULL) return TCL_ERROR;
+\fBTcl_AppendObjToObj\fR(objPtr, newPtr);
+return TCL_OK;
+.CE
+.PP
+but with greater convenience and efficiency when the appending
+functionality is needed.
+.PP
+\fBTcl_ObjPrintf\fR serves as a replacement for the common sequence
+.PP
+.CS
+char buf[SOME_SUITABLE_LENGTH];
+sprintf(buf, format, ...);
+\fBTcl_NewStringObj\fR(buf, -1);
+.CE
+.PP
+but with greater convenience and no need to 
+determine \fBSOME_SUITABLE_LENGTH\fR. The formatting is done with the same
+core formatting engine used by \fBTcl_Format\fR.  This means the set of
+supported conversion specifiers is that of the \fBformat\fR command and
+not that of the \fBsprintf\fR routine where the two sets differ. When a
+conversion specifier passed to \fBTcl_ObjPrintf\fR includes a precision,
+the value is taken as a number of bytes, as \fBsprintf\fR does, and not
+as a number of characters, as \fBformat\fR does.  This is done on the
+assumption that C code is more likely to know how many bytes it is
+passing around than the number of encoded characters those bytes happen
+to represent.  The variable number of arguments passed in should be of
+the types that would be suitable for passing to \fBsprintf\fR.  Note in
+this example usage, \fIx\fR is of type \fBint\fR.
+.PP
+.CS
+int x = 5;
+Tcl_Obj *objPtr = \fBTcl_ObjPrintf\fR("Value is %d", x);
+.CE
+.PP
+If the value of \fIformat\fR contains internal inconsistencies or invalid
+specifier formats, the formatted string result produced by
+\fBTcl_ObjPrintf\fR will be an error message describing the error. 
+It is impossible however to provide runtime protection against 
+mismatches between the format and any subsequent arguments.
+Compile-time protection may be provided by some compilers.
+.PP
+\fBTcl_AppendPrintfToObj\fR is an appending alternative form
+of \fBTcl_ObjPrintf\fR with functionality equivalent to
+.PP
+.CS
+\fBTcl_AppendObjToObj\fR(objPtr, \fBTcl_ObjPrintf\fR(format, ...));
+.CE
+.PP
+but with greater convenience and efficiency when the appending
+functionality is needed.
+.PP
+The \fBTcl_SetObjLength\fR procedure changes the length of the
+string value of its \fIobjPtr\fR argument.  If the \fInewLength\fR
+argument is greater than the space allocated for the value's
+string, then the string space is reallocated and the old value
+is copied to the new space; the bytes between the old length of
+the string and the new length may have arbitrary values.
+If the \fInewLength\fR argument is less than the current length
+of the value's string, with \fIobjPtr->length\fR is reduced without
+reallocating the string space; the original allocated size for the
+string is recorded in the value, so that the string length can be
+enlarged in a subsequent call to \fBTcl_SetObjLength\fR without
+reallocating storage.  In all cases \fBTcl_SetObjLength\fR leaves
+a null character at \fIobjPtr->bytes[newLength]\fR.
+.PP
+\fBTcl_AttemptSetObjLength\fR is identical in function to
+\fBTcl_SetObjLength\fR except that if sufficient memory to satisfy the
+request cannot be allocated, it does not cause the Tcl interpreter to
+\fBpanic\fR.  Thus, if \fInewLength\fR is greater than the space
+allocated for the value's string, and there is not enough memory
+available to satisfy the request, \fBTcl_AttemptSetObjLength\fR will take
+no action and return 0 to indicate failure.  If there is enough memory
+to satisfy the request, \fBTcl_AttemptSetObjLength\fR behaves just like
+\fBTcl_SetObjLength\fR and returns 1 to indicate success.
+.PP
+The \fBTcl_ConcatObj\fR function returns a new string value whose
+value is the space-separated concatenation of the string
+representations of all of the values in the \fIobjv\fR
+array. \fBTcl_ConcatObj\fR eliminates leading and trailing white space
+as it copies the string representations of the \fIobjv\fR array to the
+result. If an element of the \fIobjv\fR array consists of nothing but
+white space, then that value is ignored entirely. This white-space
+removal was added to make the output of the \fBconcat\fR command
+cleaner-looking. \fBTcl_ConcatObj\fR returns a pointer to a
+newly-created value whose ref count is zero.

+.SH DESCRIPTION
+.PP
+The \fBTcl_SubstObj\fR function is used to perform substitutions on
+strings in the fashion of the \fBsubst\fR command.  It gets the value

+.TH TCL_MEM_DEBUG 3 8.1 Tcl "Tcl Library Procedures"
+.BS
+.SH NAME
+TCL_MEM_DEBUG \- Compile-time flag to enable Tcl memory debugging
+.BE
+.SH DESCRIPTION
+When Tcl is compiled with \fBTCL_MEM_DEBUG\fR defined, a powerful set
+of memory debugging aids is included in the compiled binary.  This
+includes C and Tcl functions which can aid with debugging
+memory leaks, memory allocation overruns, and other memory related
+errors.
+.SH "ENABLING MEMORY DEBUGGING"
+.PP
+To enable memory debugging, Tcl should be recompiled from scratch with
+\fBTCL_MEM_DEBUG\fR defined (e.g. by passing the
+\fI\-\-enable\-symbols=mem\fR flag to the \fIconfigure\fR script when
+building).  This will also compile in a non-stub
+version of \fBTcl_InitMemory\fR to add the \fBmemory\fR command to Tcl.
+.PP
+\fBTCL_MEM_DEBUG\fR must be either left defined for all modules or undefined
+for all modules that are going to be linked together.  If they are not, link
+errors will occur, with either \fBTcl_DbCkfree\fR and \fBTcl_DbCkalloc\fR or
+\fBTcl_Alloc\fR and \fBTcl_Free\fR being undefined.
+.PP
+Once memory debugging support has been compiled into Tcl, the C
+functions \fBTcl_ValidateAllMemory\fR, and \fBTcl_DumpActiveMemory\fR,
+and the Tcl \fBmemory\fR command can be used to validate and examine
+memory usage.
+.SH "GUARD ZONES"
+.PP
+When memory debugging is enabled, whenever a call to \fBckalloc\fR is
+made, slightly more memory than requested is allocated so the memory
+debugging code can keep track of the allocated memory, and eight-byte
+.QW "guard zones"
+are placed in front of and behind the space that will be
+returned to the caller.  (The sizes of the guard zones are defined by the
+C #define \fBLOW_GUARD_SIZE\fR and #define \fBHIGH_GUARD_SIZE\fR
+in the file \fIgeneric/tclCkalloc.c\fR \(em it can
+be extended if you suspect large overwrite problems, at some cost in
+performance.)  A known pattern is written into the guard zones and, on
+a call to \fBckfree\fR, the guard zones of the space being freed are
+checked to see if either zone has been modified in any way.  If one
+has been, the guard bytes and their new contents are identified, and a
+.QW "low guard failed"
+or
+.QW "high guard failed"
+message is issued.  The
+.QW "guard failed"
+message includes the address of the memory packet and
+the file name and line number of the code that called \fBckfree\fR.
+This allows you to detect the common sorts of one-off problems, where
+not enough space was allocated to contain the data written, for
+example.
+.SH "DEBUGGING DIFFICULT MEMORY CORRUPTION PROBLEMS"
+.PP
+Normally, Tcl compiled with memory debugging enabled will make it easy
+to isolate a corruption problem.  Turning on memory validation with
+the memory command can help isolate difficult problems.  If you
+suspect (or know) that corruption is occurring before the Tcl
+interpreter comes up far enough for you to issue commands, you can set
+\fBMEM_VALIDATE\fR define, recompile tclCkalloc.c and rebuild Tcl.
+This will enable memory validation from the first call to
+\fBckalloc\fR, again, at a large performance impact.
+.PP
+If you are desperate and validating memory on every call to
+\fBckalloc\fR and \fBckfree\fR is not enough, you can explicitly call
+\fBTcl_ValidateAllMemory\fR directly at any point.  It takes a \fIchar
+*\fR and an \fIint\fR which are normally the filename and line number
+of the caller, but they can actually be anything you want.  Remember
+to remove the calls after you find the problem.

+.SH NAME
+Tcl \- Tool Command Language
+.SH SYNOPSIS
+Summary of Tcl language syntax.
+.BE
+.SH DESCRIPTION
+.PP
+The following rules define the syntax and semantics of the Tcl language:
+.IP "[1] \fBCommands.\fR"
+A Tcl script is a string containing one or more commands.
+Semi-colons and newlines are command separators unless quoted as
+described below.
+Close brackets are command terminators during command substitution
+(see below) unless quoted.
+.IP "[2] \fBEvaluation.\fR"
+A command is evaluated in two steps.
+First, the Tcl interpreter breaks the command into \fIwords\fR
+and performs substitutions as described below.
+These substitutions are performed in the same way for all
+commands.
+The first word is used to locate a command procedure to

+Different commands interpret their words differently.
+.IP "[3] \fBWords.\fR"
+Words of a command are separated by white space (except for
+newlines, which are command separators).
+.IP "[4] \fBDouble quotes.\fR"
+If the first character of a word is double-quote

+If semi-colons, close brackets, or white space characters
+(including newlines) appear between the quotes then they are treated
+as ordinary characters and included in the word.
+Command substitution, variable substitution, and backslash substitution
+are performed on the characters between the quotes as described below.
+The double-quotes are not retained as part of the word.
+.IP "[5] \fBArgument expansion.\fR"
+If a word starts with the string
+.QW {*}
+followed by a non-whitespace character, then the leading
+.QW {*}
+is removed and the rest of the word is parsed and substituted as any other
+word. After substitution, the word is parsed as a list (without command or
+variable substitutions; backslash substitutions are performed as is normal for
+a list and individual internal words may be surrounded by either braces or
+double-quote characters), and its words are added to the command being
+substituted. For instance,
+.QW "cmd a {*}{b [c]} d {*}{$e f {g h}}"
+is equivalent to
+.QW "cmd a b {[c]} d {$e} f {g h}" .
+.IP "[6] \fBBraces.\fR"
+If the first character of a word is an open brace
+.PQ {
+and rule [5] does not apply, then
+the word is terminated by the matching close brace
+.PQ } "" .
+Braces nest within the word: for each additional open
+brace there must be an additional close brace (however,
+if an open brace or close brace within the word is
+quoted with a backslash then it is not counted in locating the
+matching close brace).
+No substitutions are performed on the characters between the
+braces except for backslash-newline substitutions described
+below, nor do semi-colons, newlines, close brackets,
+or white space receive any special interpretation.
+The word will consist of exactly the characters between the
+outer braces, not including the braces themselves.
+.IP "[7] \fBCommand substitution.\fR"
+If a word contains an open bracket
+.PQ [
+then Tcl performs \fIcommand substitution\fR.
+To do this it invokes the Tcl interpreter recursively to process
+the characters following the open bracket as a Tcl script.
+The script may contain any number of commands and must be terminated

+The result of the script (i.e. the result of its last command) is
+substituted into the word in place of the brackets and all of the

+.BE
+.SH DESCRIPTION
+These functions form the interface from the Tcl library to the Zlib
+library by Jean-loup Gailly and Mark Adler.
+.PP
+\fBTcl_ZlibDeflate\fR and \fBTcl_ZlibInflate\fR respectively compress and
+decompress the data contained in the \fIdataObj\fR argument, according to the
+\fIformat\fR and, for compression, \fIlevel\fR arguments. The dictionary in
+the \fIdictObj\fR parameter is used to convey additional header information
+about the compressed data when the compression format supports it; currently,
+the dictionary is only used when the \fIformat\fR parameter is
+\fBTCL_ZLIB_FORMAT_GZIP\fR or \fBTCL_ZLIB_FORMAT_AUTO\fR. For details of the
+contents of the dictionary, see the \fBGZIP OPTIONS DICTIONARY\fR section
+below. Upon success, both functions leave the resulting compressed or
+decompressed data in a byte-array value that is the Tcl interpreter's result;
+the returned value is a standard Tcl result code.
+.PP
+\fBTcl_ZlibAdler32\fR and \fBTcl_ZlibCRC32\fR compute checksums on arrays of
+bytes, returning the computed checksum. Checksums are computed incrementally,
+allowing data to be processed one block at a time, but this requires the
+caller to maintain the current checksum and pass it in as the \fIinitValue\fR
+parameter; the initial value to use for this can be obtained by using NULL for
+the \fIbytes\fR parameter instead of a pointer to the array of bytes to
+compute the checksum over. Thus, typical usage in the single data block case
+is like this:
+.PP
+.CS
+checksum = \fBTcl_ZlibCRC32\fR(\fBTcl_ZlibCRC32\fR(0,NULL,0), data, length);
+.CE
+.PP
+Note that the Adler-32 algorithm is not a real checksum, but instead is a
+related type of hash that works best on longer data.
+.SS "ZLIB STREAMS"
+.PP
+\fBTcl_ZlibStreamInit\fR creates a compressing or decompressing stream that is
+linked to a Tcl command, according to its arguments, and provides an abstract
+token for the stream and returns a normal Tcl result code;
+\fBTcl_ZlibStreamGetCommandName\fR returns the name of that command given the
+stream token, or NULL if the stream has no command. Streams are not designed
+to be thread-safe; each stream should only ever be used from the thread that
+created it. When working with gzip streams, a dictionary (fields as given in
+the \fBGZIP OPTIONS DICTIONARY\fR section below) can be given via the
+\fIdictObj\fR parameter that on compression allows control over the generated
+headers, and on decompression allows discovery of the existing headers. Note
+that the dictionary will be written to on decompression once sufficient data
+has been read to have a complete header. This means that the dictionary must
+be an unshared value in that case; a blank value created with
+\fBTcl_NewObj\fR is suggested.
+.PP
+Once a stream has been constructed, \fBTcl_ZlibStreamPut\fR is used to add
+data to the stream and \fBTcl_ZlibStreamGet\fR is used to retrieve data from
+the stream after processing. Both return normal Tcl result codes and leave an
+error message in the result of the interpreter that the stream is registered
+with in the error case (if such a registration has been performed). With
+\fBTcl_ZlibStreamPut\fR, the data buffer value passed to it should not be
+modified afterwards. With \fBTcl_ZlibStreamGet\fR, the data buffer value
+passed to it will have the data bytes appended to it. Internally to the
+stream, data is kept compressed so as to minimize the cost of buffer space.
+.PP
+\fBTcl_ZlibStreamChecksum\fR returns the checksum computed over the
+uncompressed data according to the format, and \fBTcl_ZlibStreamEof\fR returns
+a boolean value indicating whether the end of the uncompressed data has been
+reached.
+.PP
+\fBTcl_ZlibStreamSetCompressionDictionary\fR is used to control the
+compression dictionary used with the stream, a compression dictionary being an
+array of bytes (such as might be created with \fBTcl_NewByteArrayObj\fR) that
+is used to initialize the compression engine rather than leaving it to create
+it on the fly from the data being compressed. Setting a compression dictionary
+allows for more efficient compression in the case where the start of the data
+is highly regular, but it does require both the compressor and the
+decompressor to agreee on the value to use. Compression dictionaries are only
+fully supported for zlib-format data; on compression, they must be set before
+any data is sent in with \fBTcl_ZlibStreamPut\fR, and on decompression they
+should be set when \fBTcl_ZlibStreamGet\fR produces an \fBerror\fR with its
+\fB\-errorcode\fR set to
+.QW "\fBZLIB NEED_DICT\fI code\fR" ;
+the \fIcode\fR will be the Adler-32 checksum (see \fBTcl_ZlibAdler32\fR) of
+the compression dictionary sought. (Note that this is only true for
+zlib-format streams; gzip streams ignore compression dictionaries as the
+format specification doesn't permit them, and raw streams just produce a data
+error if the compression dictionary is missing or incorrect.)
+.PP
+If you wish to clear a stream and reuse it for a new compression or
+decompression action, \fBTcl_ZlibStreamReset\fR will do this and return a
+normal Tcl result code to indicate whether it was successful; if the stream is
+registered with an interpreter, an error message will be left in the
+interpreter result when this function returns TCL_ERROR.
+Finally, \fBTcl_ZlibStreamClose\fR will clean up the stream and delete the
+associated command: using \fBTcl_DeleteCommand\fR on the stream's command is
+equivalent (when such a command exists).
+.SH "GZIP OPTIONS DICTIONARY"
+.PP
+The \fIdictObj\fR parameter to \fBTcl_ZlibDeflate\fR, \fBTcl_ZlibInflate\fR
+and \fBTcl_ZlibStreamInit\fR is used to pass a dictionary of options about
+that is used to describe the gzip header in the compressed data. When creating
+compressed data, the dictionary is read and when unpacking compressed data the
+dictionary is written (in which case the \fIdictObj\fR parameter must refer to
+an unshared dictionary value).
+.PP
+The following fields in the dictionary value are understood. All other fields
+are ignored. No field is required when creating a gzip-format stream.
+.TP
+\fBcomment\fR
+.
+This holds the comment field of the header, if present. If absent, no comment
+was supplied (on decompression) or will be created (on compression).
+.TP
+\fBcrc\fR
+.
+A boolean value describing whether a CRC of the header is computed. Note that
+the \fBgzip\fR program does \fInot\fR use or allow a CRC on the header.
+.TP
+\fBfilename\fR
+.
+The name of the file that held the uncompressed data. This should not contain
+any directory separators, and should be sanitized before use on decompression
+with \fBfile tail\fR.
+.TP
+\fBos\fR
+.
+The operating system type code field from the header (if not the
+.QW unknown
+value). See RFC 1952 for the meaning of these codes. On compression, if this
+is absent then the field will be set to the
+.QW unknown
+value.
+.TP
+\fBsize\fR
+.
+The size of the uncompressed data. This is ignored on compression; the size
+of the data compressed depends on how much data is supplied to the
+compression engine.
+.TP
+\fBtime\fR
+.
+The time field from the header if non-zero, expected to be the time that the
+file named by the \fBfilename\fR field was modified. Suitable for use with
+\fBclock format\fR. On creation, the right value to use is that from
+\fBclock seconds\fR or \fBfile mtime\fR.
+.TP
+\fBtype\fR
+.
+The type of the uncompressed data (either \fBbinary\fR or \fBtext\fR) if
+known.

+.SH DESCRIPTION
+.PP
+\fBTcl_Main\fR can serve as the main program for Tcl-based shell
+applications.  A
+.QW "shell application"
+is a program
+like tclsh or wish that supports both interactive interpretation
+of Tcl and evaluation of a script contained in a file given as
+a command line argument.  \fBTcl_Main\fR is offered as a convenience
+to developers of shell applications, so they do not have to 
+reproduce all of the code for proper initialization of the Tcl
+library and interactive shell operation.  Other styles of embedding
+Tcl in an application are not supported by \fBTcl_Main\fR.  Those
+must be achieved by calling lower level functions in the Tcl library
+directly.
+.PP
+The \fBTcl_Main\fR function has been offered by the Tcl library
+since release Tcl 7.4.  In older releases of Tcl, the Tcl library
+itself defined a function \fBmain\fR, but that lacks flexibility
+of embedding style and having a function \fBmain\fR in a library
+(particularly a shared library) causes problems on many systems.
+Having \fBmain\fR in the Tcl library would also make it hard to use
+Tcl in C++ programs, since C++ programs must have special C++
+\fBmain\fR functions.
+.PP
+Normally each shell application contains a small \fBmain\fR function
+that does nothing but invoke \fBTcl_Main\fR.
+\fBTcl_Main\fR then does all the work of creating and running a
+\fBtclsh\fR-like application.
+.PP
+\fBTcl_Main\fR is not provided by the public interface of Tcl's
+stub library.  Programs that call \fBTcl_Main\fR must be linked
+against the standard Tcl library.  Extensions (stub-enabled or
+not) are not intended to call \fBTcl_Main\fR.
+.PP
+\fBTcl_Main\fR is not thread-safe.  It should only be called by
+a single master thread of a multi-threaded application.  This
+restriction is not a problem with normal use described above.
+.PP
+\fBTcl_Main\fR and therefore all applications based upon it, like
+\fBtclsh\fR, use \fBTcl_GetStdChannel\fR to initialize the standard
+channels to their default values. See \fBTcl_StandardChannels\fR for
+more information.
+.PP
+\fBTcl_Main\fR supports two modes of operation, depending on
+whether the filename and encoding of a startup script has been
+established.  The routines \fBTcl_SetStartupScript\fR and
+\fBTcl_GetStartupScript\fR are the tools for controlling this
+configuration of \fBTcl_Main\fR.
+.PP
+\fBTcl_SetStartupScript\fR registers the value \fIpath\fR
+as the name of the file for \fBTcl_Main\fR to evaluate as
+its startup script.  The value \fIencoding\fR is Tcl's name
+for the encoding used to store the text in that file.  A
+value of \fBNULL\fR for \fIencoding\fR is a signal to use
+the system encoding.  A value of \fBNULL\fR for \fIpath\fR
+erases any existing registration so that \fBTcl_Main\fR
+will not evaluate any startup script.
+.PP
+\fBTcl_GetStartupScript\fR queries the registered file name
+and encoding set by the most recent \fBTcl_SetStartupScript\fR
+call in the same thread.  The stored file name is returned,
+and the stored encoding name is written to space pointed to
+by \fIencodingPtr\fR, when that is not NULL.  
+.PP
+The file name and encoding values managed by the routines
+\fBTcl_SetStartupScript\fR and \fBTcl_GetStartupScript\fR
+are stored per-thread.  Although the storage and retrieval
+functions of these routines work in any thread, only those
+calls in the same master thread as \fBTcl_Main\fR can have
+any influence on it.
+.PP
+The caller of \fBTcl_Main\fR may call \fBTcl_SetStartupScript\fR
+first to establish its desired startup script.  If \fBTcl_Main\fR
+finds that no such startup script has been established, it consults
+the first few arguments in \fIargv\fR.  If they match
+?\fB\-encoding \fIname\fR? \fIfileName\fR,
+where \fIfileName\fR does not begin with the character \fI\-\fR,
+then \fIfileName\fR is taken to be the name of a file containing
+a \fIstartup script\fR, and \fIname\fR is taken to be the name
+of the encoding of the contents of that file.  \fBTcl_Main\fR
+then calls \fBTcl_SetStartupScript\fR with these values.
+.PP
+\fBTcl_Main\fR then defines in its master interpreter
+the Tcl variables \fIargc\fR, \fIargv\fR, \fIargv0\fR, and
+\fItcl_interactive\fR, as described in the documentation for \fBtclsh\fR.
+.PP
+When it has finished its own initialization, but before it processes
+commands, \fBTcl_Main\fR calls the procedure given by the
+\fIappInitProc\fR argument.  This procedure provides a
+.QW hook
+for the application to perform its own initialization of the interpreter
+created by \fBTcl_Main\fR, such as defining application-specific
+commands.  The application initialization routine might also 
+call \fBTcl_SetStartupScript\fR to (re-)set the file and encoding
+to be used as a startup script.  The procedure must have an interface
+that matches the type \fBTcl_AppInitProc\fR:
+.PP
+.CS
+typedef int \fBTcl_AppInitProc\fR(
+        Tcl_Interp *\fIinterp\fR);
+.CE
+.PP
+\fIAppInitProc\fR is almost always a pointer to \fBTcl_AppInit\fR; for more
+details on this procedure, see the documentation for \fBTcl_AppInit\fR.
+.PP
+When the \fIappInitProc\fR is finished, \fBTcl_Main\fR calls
+\fBTcl_GetStartupScript\fR to determine what startup script has
+been requested, if any.  If a startup script has been provided,
+\fBTcl_Main\fR attempts to evaluate it.  Otherwise, interactive
+mode begins with examination of the variable \fItcl_rcFileName\fR
+in the master interpreter.  If that variable exists and holds the
+name of a readable file, the contents of that file are evaluated
+in the master interpreter.  Then interactive operations begin,
+with prompts and command evaluation results written to the standard
+output channel, and commands read from the standard input channel
+and then evaluated.  The prompts written to the standard output
+channel may be customized by defining the Tcl variables \fItcl_prompt1\fR
+and \fItcl_prompt2\fR as described in the documentation for \fBtclsh\fR.
+The prompts and command evaluation results are written to the standard
+output channel only if the Tcl variable \fItcl_interactive\fR in the
+master interpreter holds a non-zero integer value.
+.PP
+\fBTcl_SetMainLoop\fR allows setting an event loop procedure to be run.
+This allows, for example, Tk to be dynamically loaded and set its event
+loop.  The event loop will run following the startup script.  If you
+are in interactive mode, setting the main loop procedure will cause the
+prompt to become fileevent based and then the loop procedure is called.
+When the loop procedure returns in interactive mode, interactive operation
+will continue.
+The main loop procedure must have an interface that matches the type
+\fBTcl_MainLoopProc\fR:
+.PP
+.CS
+typedef void \fBTcl_MainLoopProc\fR(void);
+.CE
+.PP
+\fBTcl_Main\fR does not return.  Normally a program based on
+\fBTcl_Main\fR will terminate when the \fBexit\fR command is
+evaluated.  In interactive mode, if an EOF or channel error
+is encountered on the standard input channel, then \fBTcl_Main\fR
+itself will evaluate the \fBexit\fR command after the main loop
+procedure (if any) returns.  In non-interactive mode, after
+\fBTcl_Main\fR evaluates the startup script, and the main loop
+procedure (if any) returns, \fBTcl_Main\fR will also evaluate
+the \fBexit\fR command.

+.SH INTRODUCTION
+Beginning with the 8.1 release, the Tcl core is thread safe, which
+allows you to incorporate Tcl into multithreaded applications without
+customizing the Tcl core.  To enable Tcl multithreading support,
+you must include the \fB\-\|\-enable-threads\fR option to \fBconfigure\fR
+when you configure and compile your Tcl core.
+.PP
+An important constraint of the Tcl threads implementation is that
+\fIonly the thread that created a Tcl interpreter can use that
+interpreter\fR.  In other words, multiple threads can not access
+the same Tcl interpreter.  (However, a single thread can safely create
+and use multiple interpreters.)
+.SH DESCRIPTION
+Tcl provides \fBTcl_CreateThread\fR for creating threads. The
+caller can determine the size of the stack given to the new thread and
+modify the behavior through the supplied \fIflags\fR. The value
+\fBTCL_THREAD_STACK_DEFAULT\fR for the \fIstackSize\fR indicates that
+the default size as specified by the operating system is to be used
+for the new thread. As for the flags, currently only the values
+\fBTCL_THREAD_NOFLAGS\fR and \fBTCL_THREAD_JOINABLE\fR are defined. The
+first of them invokes the default behavior with no special settings.
+Using the second value marks the new thread as \fIjoinable\fR. This
+means that another thread can wait for the such marked thread to exit
+and join it.
+.PP
+Restrictions: On some UNIX systems the pthread-library does not
+contain the functionality to specify the stack size of a thread. The
+specified value for the stack size is ignored on these systems.
+Windows currently does not support joinable threads. This
+flag value is therefore ignored on this platform.
+.PP
+Tcl provides the \fBTcl_ExitThread\fR and \fBTcl_FinalizeThread\fR functions
+for terminating threads and invoking optional per-thread exit
+handlers.  See the \fBTcl_Exit\fR page for more information on these
+procedures.
+.PP
+The \fBTcl_JoinThread\fR function is provided to allow threads to wait
+upon the exit of another thread, which must have been marked as
+joinable through usage of the \fBTCL_THREAD_JOINABLE\fR-flag during
+its creation via \fBTcl_CreateThread\fR.
+.PP
+Trying to wait for the exit of a non-joinable thread or a thread which
+is already waited upon will result in an error. Waiting for a joinable
+thread which already exited is possible, the system will retain the
+necessary information until after the call to \fBTcl_JoinThread\fR.
+This means that not calling \fBTcl_JoinThread\fR for a joinable thread
+will cause a memory leak.
+.PP
+The \fBTcl_GetThreadData\fR call returns a pointer to a block of
+thread-private data.  Its argument is a key that is shared by all threads
+and a size for the block of storage.  The storage is automatically 
+allocated and initialized to all zeros the first time each thread asks for it.
+The storage is automatically deallocated by \fBTcl_FinalizeThread\fR.
+.SS "SYNCHRONIZATION AND COMMUNICATION"
+Tcl provides \fBTcl_ThreadQueueEvent\fR and \fBTcl_ThreadAlert\fR
+for handling event queuing in multithreaded applications.  See
+the \fBNotifier\fR manual page for more information on these procedures.
+.PP
+A mutex is a lock that is used to serialize all threads through a piece
+of code by calling \fBTcl_MutexLock\fR and \fBTcl_MutexUnlock\fR.
+If one thread holds a mutex, any other thread calling \fBTcl_MutexLock\fR will
+block until \fBTcl_MutexUnlock\fR is called.
+A mutex can be destroyed after its use by calling \fBTcl_MutexFinalize\fR.
+The result of locking a mutex twice from the same thread is undefined.
+On some platforms it will result in a deadlock.
+The \fBTcl_MutexLock\fR, \fBTcl_MutexUnlock\fR and \fBTcl_MutexFinalize\fR
+procedures are defined as empty macros if not compiling with threads enabled.
+For declaration of mutexes the \fBTCL_DECLARE_MUTEX\fR macro should be used.
+This macro assures correct mutex handling even when the core is compiled
+without threads enabled.
+.PP
+A condition variable is used as a signaling mechanism:
+a thread can lock a mutex and then wait on a condition variable
+with \fBTcl_ConditionWait\fR.  This atomically releases the mutex lock
+and blocks the waiting thread until another thread calls
+\fBTcl_ConditionNotify\fR.  The caller of \fBTcl_ConditionNotify\fR should
+have the associated mutex held by previously calling \fBTcl_MutexLock\fR,
+but this is not enforced.  Notifying the
+condition variable unblocks all threads waiting on the condition variable,
+but they do not proceed until the mutex is released with \fBTcl_MutexUnlock\fR.
+The implementation of \fBTcl_ConditionWait\fR automatically locks
+the mutex before returning.
+.PP
+The caller of \fBTcl_ConditionWait\fR should be prepared for spurious
+notifications by calling \fBTcl_ConditionWait\fR within a while loop
+that tests some invariant.
+.PP
+A condition variable can be destroyed after its use by calling
+\fBTcl_ConditionFinalize\fR.
+.PP
+The \fBTcl_ConditionNotify\fR, \fBTcl_ConditionWait\fR and
+\fBTcl_ConditionFinalize\fR procedures are defined as empty macros if
+not compiling with threads enabled.
+.SS INITIALIZATION
+.PP
+All of these synchronization objects are self-initializing.
+They are implemented as opaque pointers that should be NULL
+upon first use.
+The mutexes and condition variables are
+either cleaned up by process exit handlers (if living that long) or
+explicitly by calls to \fBTcl_MutexFinalize\fR or
+\fBTcl_ConditionFinalize\fR.
+Thread local storage is reclaimed during \fBTcl_FinalizeThread\fR.
+.SH "SCRIPT-LEVEL ACCESS TO THREADS"
+.PP
+Tcl provides no built-in commands for scripts to use to create,
+manage, or join threads, nor any script-level access to mutex or
+condition variables.  It provides such facilities only via C
+interfaces, and leaves it up to packages to expose these matters to
+the script level.  One such package is the \fBThread\fR package.
+.SH EXAMPLE
+.PP
+To create a thread with portable code, its implementation function should be
+declared as follows:
+.PP
+.CS
+static \fBTcl_ThreadCreateProc\fR MyThreadImplFunc;
+.CE
+.PP
+It should then be defined like this example, which just counts up to a given
+value and then finishes.
+.PP
+.CS
+static \fBTcl_ThreadCreateType\fR
+MyThreadImplFunc(
+    ClientData clientData)
+{
+    int i, limit = (int) clientData;
+    for (i=0 ; i<limit ; i++) {
+        /* doing nothing at all here */
+    }
+    \fBTCL_THREAD_CREATE_RETURN\fR;
+}
+.CE
+.PP
+To create the above thread, make it execute, and wait for it to finish, we
+would do this:
+.PP
+.CS
+int limit = 1000000000;
+ClientData limitData = (void*)((intptr_t) limit);
+Tcl_ThreadId id;    \fI/* holds identity of thread created */\fR
+int result;
+
+if (\fBTcl_CreateThread\fR(&id, MyThreadImplFunc, limitData,
+        \fBTCL_THREAD_STACK_DEFAULT\fR,
+        \fBTCL_THREAD_JOINABLE\fR) != TCL_OK) {
+    \fI/* Thread did not create correctly */\fR
+    return;
+}
+\fI/* Do something else for a while here */\fR
+if (\fBTcl_JoinThread\fR(id, &result) != TCL_OK) {
+    \fI/* Thread did not finish properly */\fR
+    return;
+}
+\fI/* All cleaned up nicely */\fR

+.PP
+The first three routines convert the case of individual Unicode characters:
+.PP
+If \fIch\fR represents a lower-case character,
+\fBTcl_UniCharToUpper\fR returns the corresponding upper-case
+character.  If no upper-case character is defined, it returns the
+character unchanged.
+.PP
+If \fIch\fR represents an upper-case character,
+\fBTcl_UniCharToLower\fR returns the corresponding lower-case
+character.  If no lower-case character is defined, it returns the
+character unchanged.
+.PP
+If \fIch\fR represents a lower-case character,
+\fBTcl_UniCharToTitle\fR returns the corresponding title-case
+character.  If no title-case character is defined, it returns the
+corresponding upper-case character.  If no upper-case character is
+defined, it returns the character unchanged.  Title-case is defined
+for a small number of characters that have a different appearance when
+they are at the beginning of a capitalized word.
+.PP
+The next three routines convert the case of UTF-8 strings in place in
+memory:
+.PP
+\fBTcl_UtfToUpper\fR changes every UTF-8 character in \fIstr\fR to
+upper-case.  Because changing the case of a character may change its
+size, the byte offset of each character in the resulting string may
+differ from its original location.  \fBTcl_UtfToUpper\fR writes a null
+byte at the end of the converted string.  \fBTcl_UtfToUpper\fR returns
+the new length of the string in bytes.  This new length is guaranteed
+to be no longer than the original string length.
+.PP
+\fBTcl_UtfToLower\fR is the same as \fBTcl_UtfToUpper\fR except it
+turns each character in the string into its lower-case equivalent.
+.PP
+\fBTcl_UtfToTitle\fR is the same as \fBTcl_UtfToUpper\fR except it
+turns the first character in the string into its title-case equivalent
+and all following characters into their lower-case equivalents.
+
+.SH BUGS
+.PP
+At this time, the case conversions are only defined for the ISO8859-1
+characters.  Unicode characters above 0x00ff are not modified by these
+routines.

+.BE
+.SH DESCRIPTION
+.PP
+\fBTcl_TraceCommand\fR allows a C procedure to monitor operations
+performed on a Tcl command, so that the C procedure is invoked
+whenever the command is renamed or deleted.  If the trace is created
+successfully then \fBTcl_TraceCommand\fR returns \fBTCL_OK\fR. If an error
+occurred (e.g. \fIcmdName\fR specifies a non-existent command) then
+\fBTCL_ERROR\fR is returned and an error message is left in the
+interpreter's result.
+.PP
+The \fIflags\fR argument to \fBTcl_TraceCommand\fR indicates when the
+trace procedure is to be invoked.  It consists of an OR'ed combination
+of any of the following values:
+.TP
+\fBTCL_TRACE_RENAME\fR
+Invoke \fIproc\fR whenever the command is renamed.
+.TP
+\fBTCL_TRACE_DELETE\fR
+Invoke \fIproc\fR when the command is deleted.
+.PP
+Whenever one of the specified operations occurs to the command,
+\fIproc\fR will be invoked.  It should have arguments and result that
+match the type \fBTcl_CommandTraceProc\fR:
+.PP
+.CS
+typedef void \fBTcl_CommandTraceProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        const char *\fIoldName\fR,
+        const char *\fInewName\fR,
+        int \fIflags\fR);
+.CE
+.PP
+The \fIclientData\fR and \fIinterp\fR parameters will have the same
+values as those passed to \fBTcl_TraceCommand\fR when the trace was
+created.  \fIClientData\fR typically points to an application-specific
+data structure that describes what to do when \fIproc\fR is invoked.
+\fIOldName\fR gives the name of the command being renamed, and
+\fInewName\fR gives the name that the command is being renamed to (or
+an empty string or NULL when the command is being deleted.)
+\fIFlags\fR is an OR'ed combination of bits potentially providing
+several pieces of information.  One of the bits \fBTCL_TRACE_RENAME\fR and
+\fBTCL_TRACE_DELETE\fR will be set in \fIflags\fR to indicate which
+operation is being performed on the command.  The bit
+\fBTCL_TRACE_DESTROYED\fR will be set in \fIflags\fR if the trace is about
+to be destroyed; this information may be useful to \fIproc\fR so that
+it can clean up its own internal data structures (see the section
+\fBTCL_TRACE_DESTROYED\fR below for more details).  Lastly, the bit
+\fBTCL_INTERP_DESTROYED\fR will be set if the entire interpreter is being
+destroyed.  When this bit is set, \fIproc\fR must be especially
+careful in the things it does (see the section \fBTCL_INTERP_DESTROYED\fR
+below).
+.PP
+\fBTcl_UntraceCommand\fR may be used to remove a trace.  If the
+command specified by \fIinterp\fR, \fIcmdName\fR, and \fIflags\fR has
+a trace set with \fIflags\fR, \fIproc\fR, and \fIclientData\fR, then
+the corresponding trace is removed.  If no such trace exists, then the
+call to \fBTcl_UntraceCommand\fR has no effect.  The same bits are
+valid for \fIflags\fR as for calls to \fBTcl_TraceCommand\fR.
+.PP
+\fBTcl_CommandTraceInfo\fR may be used to retrieve information about
+traces set on a given command.
+The return value from \fBTcl_CommandTraceInfo\fR is the \fIclientData\fR
+associated with a particular trace.
+The trace must be on the command specified by the \fIinterp\fR,
+\fIcmdName\fR, and \fIflags\fR arguments (note that currently the
+flags are ignored; \fIflags\fR should be set to 0 for future
+compatibility) and its trace procedure must the same as the \fIproc\fR
+argument.
+If the \fIprevClientData\fR argument is NULL then the return
+value corresponds to the first (most recently created) matching
+trace, or NULL if there are no matching traces.

+matching trace after the one whose \fIclientData\fR matches
+\fIprevClientData\fR, or NULL if no trace matches \fIprevClientData\fR
+or if there are no more matching traces after it.
+This mechanism makes it possible to step through all of the
+traces for a given command that have the same \fIproc\fR.
+.SH "CALLING COMMANDS DURING TRACES"
+.PP
+During rename traces, the command being renamed is visible with both
+names simultaneously, and the command still exists during delete
+traces (if \fBTCL_INTERP_DESTROYED\fR is not set).  However, there is no
+mechanism for signaling that an error occurred in a trace procedure,
+so great care should be taken that errors do not get silently lost.
+.SH "MULTIPLE TRACES"
+.PP
+It is possible for multiple traces to exist on the same command.
+When this happens, all of the trace procedures will be invoked on each
+access, in order from most-recently-created to least-recently-created.
+Attempts to delete the command during a delete trace will fail
+silently, since the command is already scheduled for deletion anyway.
+If the command being renamed is renamed by one of its rename traces,
+that renaming takes precedence over the one that triggered the trace
+and the collection of traces will not be reexecuted; if several traces
+rename the command, the last renaming takes precedence.
+.SH "TCL_TRACE_DESTROYED FLAG"

+.BE
+.SH DESCRIPTION
+.PP
+\fBTcl_TraceVar\fR allows a C procedure to monitor and control
+access to a Tcl variable, so that the C procedure is invoked
+whenever the variable is read or written or unset.
+If the trace is created successfully then \fBTcl_TraceVar\fR returns
+\fBTCL_OK\fR.  If an error occurred (e.g. \fIvarName\fR specifies an element
+of an array, but the actual variable is not an array) then \fBTCL_ERROR\fR
+is returned and an error message is left in the interpreter's result.
+.PP
+The \fIflags\fR argument to \fBTcl_TraceVar\fR indicates when the
+trace procedure is to be invoked and provides information
+for setting up the trace.  It consists of an OR-ed combination
+of any of the following values:
+.TP
+\fBTCL_GLOBAL_ONLY\fR
+Normally, the variable will be looked up at the current level of
+procedure call;  if this bit is set then the variable will be looked
+up at global level, ignoring any active procedures.
+.TP
+\fBTCL_NAMESPACE_ONLY\fR
+Normally, the variable will be looked up at the current level of
+procedure call;  if this bit is set then the variable will be looked
+up in the current namespace, ignoring any active procedures.
+.TP
+\fBTCL_TRACE_READS\fR
+Invoke \fIproc\fR whenever an attempt is made to read the variable.
+.TP
+\fBTCL_TRACE_WRITES\fR
+Invoke \fIproc\fR whenever an attempt is made to modify the variable.
+.TP
+\fBTCL_TRACE_UNSETS\fR
+Invoke \fIproc\fR whenever the variable is unset.
+A variable may be unset either explicitly by an \fBunset\fR command,
+or implicitly when a procedure returns (its local variables are
+automatically unset) or when the interpreter is deleted (all
+variables are automatically unset).
+.TP
+\fBTCL_TRACE_ARRAY\fR
+Invoke \fIproc\fR whenever the array command is invoked.
+This gives the trace procedure a chance to update the array before
+array names or array get is called.  Note that this is called
+before an array set, but that will trigger write traces.
+.TP
+\fBTCL_TRACE_RESULT_DYNAMIC\fR
+The result of invoking the \fIproc\fR is a dynamically allocated
+string that will be released by the Tcl library via a call to
+\fBckfree\fR.  Must not be specified at the same time as
+\fBTCL_TRACE_RESULT_OBJECT\fR.
+.TP
+\fBTCL_TRACE_RESULT_OBJECT\fR
+The result of invoking the \fIproc\fR is a Tcl_Obj* (cast to a char*)
+with a reference count of at least one.  The ownership of that
+reference will be transferred to the Tcl core for release (when the
+core has finished with it) via a call to \fBTcl_DecrRefCount\fR.  Must
+not be specified at the same time as \fBTCL_TRACE_RESULT_DYNAMIC\fR.
+.PP
+Whenever one of the specified operations occurs on the variable,
+\fIproc\fR will be invoked.
+It should have arguments and result that match the type
+\fBTcl_VarTraceProc\fR:
+.PP
+.CS
+typedef char *\fBTcl_VarTraceProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        char *\fIname1\fR,
+        char *\fIname2\fR,
+        int \fIflags\fR);
+.CE
+.PP
+The \fIclientData\fR and \fIinterp\fR parameters will
+have the same values as those passed to \fBTcl_TraceVar\fR when the
+trace was created.
+\fIClientData\fR typically points to an application-specific
+data structure that describes what to do when \fIproc\fR
+is invoked.
+\fIName1\fR and \fIname2\fR give the name of the traced variable
+in the normal two-part form (see the description of \fBTcl_TraceVar2\fR
+below for details).
+\fIFlags\fR is an OR-ed combination of bits providing several
+pieces of information.
+One of the bits \fBTCL_TRACE_READS\fR, \fBTCL_TRACE_WRITES\fR,
+\fBTCL_TRACE_ARRAY\fR, or \fBTCL_TRACE_UNSETS\fR
+will be set in \fIflags\fR to indicate which operation is being performed
+on the variable.
+The bit \fBTCL_GLOBAL_ONLY\fR will be set whenever the variable being
+accessed is a global one not accessible from the current level of
+procedure call:  the trace procedure will need to pass this flag
+back to variable-related procedures like \fBTcl_GetVar\fR if it
+attempts to access the variable.
+The bit \fBTCL_NAMESPACE_ONLY\fR will be set whenever the variable being
+accessed is a namespace one not accessible from the current level of
+procedure call:  the trace procedure will need to pass this flag
+back to variable-related procedures like \fBTcl_GetVar\fR if it
+attempts to access the variable.
+The bit \fBTCL_TRACE_DESTROYED\fR will be set in \fIflags\fR if the trace is
+about to be destroyed;  this information may be useful to \fIproc\fR
+so that it can clean up its own internal data structures (see
+the section \fBTCL_TRACE_DESTROYED\fR below for more details).
+Lastly, the bit \fBTCL_INTERP_DESTROYED\fR will be set if the entire
+interpreter is being destroyed.
+When this bit is set, \fIproc\fR must be especially careful in
+the things it does (see the section \fBTCL_INTERP_DESTROYED\fR below).
+The trace procedure's return value should normally be NULL;  see
+\fBERROR RETURNS\fR below for information on other possibilities.
+.PP
+\fBTcl_UntraceVar\fR may be used to remove a trace.
+If the variable specified by \fIinterp\fR, \fIvarName\fR, and \fIflags\fR
+has a trace set with \fIflags\fR, \fIproc\fR, and
+\fIclientData\fR, then the corresponding trace is removed.
+If no such trace exists, then the call to \fBTcl_UntraceVar\fR
+has no effect.
+The same bits are valid for \fIflags\fR as for calls to \fBTcl_TraceVar\fR.
+.PP
+\fBTcl_VarTraceInfo\fR may be used to retrieve information about
+traces set on a given variable.
+The return value from \fBTcl_VarTraceInfo\fR is the \fIclientData\fR
+associated with a particular trace.
+The trace must be on the variable specified by the \fIinterp\fR,
+\fIvarName\fR, and \fIflags\fR arguments (only the \fBTCL_GLOBAL_ONLY\fR and
+\fBTCL_NAMESPACE_ONLY\fR bits from \fIflags\fR is used;  other bits are
+ignored) and its trace procedure must the same as the \fIproc\fR
+argument.
+If the \fIprevClientData\fR argument is NULL then the return
+value corresponds to the first (most recently created) matching
+trace, or NULL if there are no matching traces.
+If the \fIprevClientData\fR argument is not NULL, then it should
+be the return value from a previous call to \fBTcl_VarTraceInfo\fR.
+In this case, the new return value will correspond to the next
+matching trace after the one whose \fIclientData\fR matches
+\fIprevClientData\fR, or NULL if no trace matches \fIprevClientData\fR
+or if there are no more matching traces after it.
+This mechanism makes it possible to step through all of the
+traces for a given variable that have the same \fIproc\fR.
+.SH "TWO-PART NAMES"
+.PP
+The procedures \fBTcl_TraceVar2\fR, \fBTcl_UntraceVar2\fR, and
+\fBTcl_VarTraceInfo2\fR are identical to \fBTcl_TraceVar\fR,
+\fBTcl_UntraceVar\fR, and \fBTcl_VarTraceInfo\fR, respectively,
+except that the name of the variable consists of two parts.
+\fIName1\fR gives the name of a scalar variable or array,
+and \fIname2\fR gives the name of an element within an array.
+When \fIname2\fR is NULL, 
+\fIname1\fR may contain both an array and an element name:
+if the name contains an open parenthesis and ends with a
+close parenthesis, then the value between the parentheses is
+treated as an element name (which can have any string value) and
+the characters before the first open
+parenthesis are treated as the name of an array variable.
+If \fIname2\fR is NULL and \fIname1\fR does not refer
+to an array element it means that either the variable is
+a scalar or the trace is to be set on the entire array rather
+than an individual element (see WHOLE-ARRAY TRACES below for
+more information). 
+.SH "ACCESSING VARIABLES DURING TRACES"
+.PP
+During read, write, and array traces, the
+trace procedure can read, write, or unset the traced
+variable using \fBTcl_GetVar2\fR, \fBTcl_SetVar2\fR, and
+other procedures.
+While \fIproc\fR is executing, traces are temporarily disabled
+for the variable, so that calls to \fBTcl_GetVar2\fR and
+\fBTcl_SetVar2\fR will not cause \fIproc\fR or other trace procedures
+to be invoked again.
+Disabling only occurs for the variable whose trace procedure
+is active;  accesses to other variables will still be traced.
+However, if a variable is unset during a read or write trace then unset
+traces will be invoked.
+.PP
+During unset traces the variable has already been completely
+expunged.
+It is possible for the trace procedure to read or write the
+variable, but this will be a new version of the variable.
+Traces are not disabled during unset traces as they are for
+read and write traces, but existing traces have been removed
+from the variable before any trace procedures are invoked.
+If new traces are set by unset trace procedures, these traces
+will be invoked on accesses to the variable by the trace
+procedures.
+.SH "CALLBACK TIMING"
+.PP
+When read tracing has been specified for a variable, the trace
+procedure will be invoked whenever the variable's value is
+read.  This includes \fBset\fR Tcl commands, \fB$\fR-notation
+in Tcl commands, and invocations of the \fBTcl_GetVar\fR
+and \fBTcl_GetVar2\fR procedures.
+\fIProc\fR is invoked just before the variable's value is
+returned.
+It may modify the value of the variable to affect what
+is returned by the traced access.
+If it unsets the variable then the access will return an error
+just as if the variable never existed.
+.PP
+When write tracing has been specified for a variable, the
+trace procedure will be invoked whenever the variable's value
+is modified.  This includes \fBset\fR commands,
+commands that modify variables as side effects (such as
+\fBcatch\fR and \fBscan\fR), and calls to the \fBTcl_SetVar\fR
+and \fBTcl_SetVar2\fR procedures).
+\fIProc\fR will be invoked after the variable's value has been
+modified, but before the new value of the variable has been
+returned.
+It may modify the value of the variable to override the change
+and to determine the value actually returned by the traced
+access.
+If it deletes the variable then the traced access will return
+an empty string.
+.PP
+When array tracing has been specified, the trace procedure
+will be invoked at the beginning of the array command implementation,
+before any of the operations like get, set, or names have been invoked.
+The trace procedure can modify the array elements with \fBTcl_SetVar\fR
+and \fBTcl_SetVar2\fR.
+.PP
+When unset tracing has been specified, the trace procedure
+will be invoked whenever the variable is destroyed.
+The traces will be called after the variable has been
+completely unset.
+.SH "WHOLE-ARRAY TRACES"
+.PP
+If a call to \fBTcl_TraceVar\fR or \fBTcl_TraceVar2\fR specifies
+the name of an array variable without an index into the array,
+then the trace will be set on the array as a whole.
+This means that \fIproc\fR will be invoked whenever any
+element of the array is accessed in the ways specified by
+\fIflags\fR.
+When an array is unset, a whole-array trace will be invoked
+just once, with \fIname1\fR equal to the name of the array
+and \fIname2\fR NULL;  it will not be invoked once for each
+element.
+.SH "MULTIPLE TRACES"
+.PP
+It is possible for multiple traces to exist on the same variable.
+When this happens, all of the trace procedures will be invoked on each
+access, in order from most-recently-created to least-recently-created.
+When there exist whole-array traces for an array as well as
+traces on individual elements, the whole-array traces are invoked
+before the individual-element traces.
+If a read or write trace unsets the variable then all of the unset
+traces will be invoked but the remainder of the read and write traces
+will be skipped.
+.SH "ERROR RETURNS"
+.PP
+Under normal conditions trace procedures should return NULL, indicating
+successful completion.
+If \fIproc\fR returns a non-NULL value it signifies that an
+error occurred.
+The return value must be a pointer to a static character string
+containing an error message,
+unless (\fIexactly\fR one of) the \fBTCL_TRACE_RESULT_DYNAMIC\fR and
+\fBTCL_TRACE_RESULT_OBJECT\fR flags is set, which specify that the result is
+either a dynamic string (to be released with \fBckfree\fR) or a
+Tcl_Obj* (cast to char* and to be released with
+\fBTcl_DecrRefCount\fR) containing the error message.
+If a trace procedure returns an error, no further traces are
+invoked for the access and the traced access aborts with the
+given message.
+Trace procedures can use this facility to make variables
+read-only, for example (but note that the value of the variable
+will already have been modified before the trace procedure is
+called, so the trace procedure will have to restore the correct
+value).
+.PP
+The return value from \fIproc\fR is only used during read and
+write tracing.
+During unset traces, the return value is ignored and all relevant
+trace procedures will always be invoked.
+.SH "RESTRICTIONS"
+.PP
+A trace procedure can be called at any time, even when there
+is a partially formed result in the interpreter's result area.  If
+the trace procedure does anything that could damage this result (such
+as calling \fBTcl_Eval\fR) then it must save the original values of
+the interpreter's \fBresult\fR and \fBfreeProc\fR fields and restore
+them before it returns.
+.SH "UNDEFINED VARIABLES"
+.PP
+It is legal to set a trace on an undefined variable.
+The variable will still appear to be undefined until the
+first time its value is set.
+If an undefined variable is traced and then unset, the unset will fail
+with an error
+.PQ "no such variable" "" ,
+but the trace procedure will still be invoked.
+.SH "TCL_TRACE_DESTROYED FLAG"
+.PP
+In an unset callback to \fIproc\fR, the \fBTCL_TRACE_DESTROYED\fR bit
+is set in \fIflags\fR if the trace is being removed as part
+of the deletion.
+Traces on a variable are always removed whenever the variable
+is deleted;  the only time \fBTCL_TRACE_DESTROYED\fR is not set is for
+a whole-array trace invoked when only a single element of an
+array is unset.
+.SH "TCL_INTERP_DESTROYED"
+.PP
+When an interpreter is destroyed, unset traces are called for
+all of its variables.
+The \fBTCL_INTERP_DESTROYED\fR bit will be set in the \fIflags\fR
+argument passed to the trace procedures.
+Trace procedures must be extremely careful in what they do if
+the \fBTCL_INTERP_DESTROYED\fR bit is set.
+It is not safe for the procedures to invoke any Tcl procedures
+on the interpreter, since its state is partially deleted.
+All that trace procedures should do under these circumstances is
+to clean up and free their own internal data structures.
+.SH BUGS
+.PP
+Tcl does not do any error checking to prevent trace procedures
+from misusing the interpreter during traces with \fBTCL_INTERP_DESTROYED\fR
+set.
+.PP
+Array traces are not yet integrated with the Tcl \fBinfo exists\fR command,

+If needed, this dynamic string is used to store the new file name.
+At the time of the call it should be uninitialized or free.  The
+caller must eventually call \fBTcl_DStringFree\fR to free up
+anything stored here.
+.BE
+.SH DESCRIPTION
+.PP
+This utility procedure translates a file name to a platform-specific form
+which, after being converted to the appropriate encoding, is suitable for
+passing to the local operating system.  In particular, it converts
+network names into native form and does tilde substitution.  
+.PP
+However, with the advent of the newer \fBTcl_FSGetNormalizedPath\fR and
+\fBTcl_FSGetNativePath\fR, there is no longer any need to use this
+procedure.  In particular, \fBTcl_FSGetNativePath\fR performs all the
+necessary translation and encoding conversion, is virtual-filesystem
+aware, and caches the native result for faster repeated calls.
+Finally \fBTcl_FSGetNativePath\fR does not require you to free anything
+afterwards.
+.PP
+If
+\fBTcl_TranslateFileName\fR has to do tilde substitution or translate
+the name then it uses
+the dynamic string at \fI*bufferPtr\fR to hold the new string it
+generates.
+After \fBTcl_TranslateFileName\fR returns a non-NULL result, the caller must
+eventually invoke \fBTcl_DStringFree\fR to free any information
+placed in \fI*bufferPtr\fR.  The caller need not know whether or
+not \fBTcl_TranslateFileName\fR actually used the string;  \fBTcl_TranslateFileName\fR
+initializes \fI*bufferPtr\fR even if it does not use it, so the call to
+\fBTcl_DStringFree\fR will be safe in either case.
+.PP
+If an error occurs (e.g. because there was no user by the given
+name) then NULL is returned and an error message will be left
+in the interpreter's result.
+When an error occurs, \fBTcl_TranslateFileName\fR
+frees the dynamic string itself so that the caller need not call
+\fBTcl_DStringFree\fR.
+.PP
+The caller is responsible for making sure that the interpreter's result
+has its default empty value when \fBTcl_TranslateFileName\fR is invoked.

+For scalar source variables, is NULL.
+.BE
+
+.SH DESCRIPTION
+.PP
+\fBTcl_UpVar\fR and \fBTcl_UpVar2\fR provide the same functionality
+as the \fBupvar\fR command:  they make a link from a source variable
+to a destination variable, so that references to the destination are
+passed transparently through to the source.
+The name of the source variable may be specified either as a single
+string such as \fBxyx\fR or \fBa(24)\fR (by calling \fBTcl_UpVar\fR)
+or in two parts where the array name has been separated from the
+element name (by calling \fBTcl_UpVar2\fR).
+The destination variable name is specified in a single string;  it
+may not be an array element.
+.PP
+Both procedures return either \fBTCL_OK\fR or \fBTCL_ERROR\fR, and they
+leave an error message in the interpreter's result if an error occurs.
+.PP
+As with the \fBupvar\fR command, the source variable need not exist;
+if it does exist, unsetting it later does not destroy the link.  The
+destination variable may exist at the time of the call, but if so
+it must exist as a linked variable.

+.SH DESCRIPTION
+.PP
+These routines convert between UTF-8 strings and Tcl_UniChars.  A
+Tcl_UniChar is a Unicode character represented as an unsigned, fixed-size
+quantity.  A UTF-8 character is a Unicode character represented as
+a varying-length sequence of up to \fBTCL_UTF_MAX\fR bytes.  A multibyte UTF-8
+sequence consists of a lead byte followed by some number of trail bytes.
+.PP
+\fBTCL_UTF_MAX\fR is the maximum number of bytes that it takes to
+represent one Unicode character in the UTF-8 representation.
+.PP
+\fBTcl_UniCharToUtf\fR stores the Tcl_UniChar \fIch\fR as a UTF-8 string
+in starting at \fIbuf\fR.  The return value is the number of bytes stored
+in \fIbuf\fR.
+.PP
+\fBTcl_UtfToUniChar\fR reads one UTF-8 character starting at \fIsrc\fR
+and stores it as a Tcl_UniChar in \fI*chPtr\fR.  The return value is the
+number of bytes read from \fIsrc\fR.  The caller must ensure that the
+source buffer is long enough such that this routine does not run off the
+end and dereference non-existent or random memory; if the source buffer
+is known to be null-terminated, this will not happen.  If the input is
+not in proper UTF-8 format, \fBTcl_UtfToUniChar\fR will store the first
+byte of \fIsrc\fR in \fI*chPtr\fR as a Tcl_UniChar between 0x0000 and
+0x00ff and return 1.  
+.PP
+\fBTcl_UniCharToUtfDString\fR converts the given Unicode string
+to UTF-8, storing the result in a previously initialized \fBTcl_DString\fR.
+You must specify \fIuniLength\fR, the length of the given Unicode string.
+The return value is a pointer to the UTF-8 representation of the
+Unicode string.  Storage for the return value is appended to the
+end of the \fBTcl_DString\fR.
+.PP
+\fBTcl_UtfToUniCharDString\fR converts the given UTF-8 string to Unicode,
+storing the result in the previously initialized \fBTcl_DString\fR.
+In the argument \fIlength\fR, you may either specify the length of
+the given UTF-8 string in bytes or
+.QW \-1 ,
+in which case \fBTcl_UtfToUniCharDString\fR uses \fBstrlen\fR to
+calculate the length.  The return value is a pointer to the Unicode
+representation of the UTF-8 string.  Storage for the return value
+is appended to the end of the \fBTcl_DString\fR.  The Unicode string
+is terminated with a Unicode null character.
+.PP
+\fBTcl_UniCharLen\fR corresponds to \fBstrlen\fR for Unicode
+characters.  It accepts a null-terminated Unicode string and returns
+the number of Unicode characters (not bytes) in that string.
+.PP
+\fBTcl_UniCharNcmp\fR and \fBTcl_UniCharNcasecmp\fR correspond to
+\fBstrncmp\fR and \fBstrncasecmp\fR, respectively, for Unicode characters.
+They accept two null-terminated Unicode strings and the number of characters
+to compare.  Both strings are assumed to be at least \fInumChars\fR characters
+long. \fBTcl_UniCharNcmp\fR  compares the two strings character-by-character
+according to the Unicode character ordering.  It returns an integer greater
+than, equal to, or less than 0 if the first string is greater than, equal
+to, or less than the second string respectively.  \fBTcl_UniCharNcasecmp\fR
+is the Unicode case insensitive version.
+.PP
+\fBTcl_UniCharCaseMatch\fR is the Unicode equivalent to
+\fBTcl_StringCaseMatch\fR.  It accepts a null-terminated Unicode string,
+a Unicode pattern, and a boolean value specifying whether the match should
+be case sensitive and returns whether the string matches the pattern.
+.PP
+\fBTcl_UtfNcmp\fR corresponds to \fBstrncmp\fR for UTF-8 strings. It
+accepts two null-terminated UTF-8 strings and the number of characters
+to compare.  (Both strings are assumed to be at least \fInumChars\fR
+characters long.)  \fBTcl_UtfNcmp\fR compares the two strings
+character-by-character according to the Unicode character ordering.
+It returns an integer greater than, equal to, or less than 0 if the
+first string is greater than, equal to, or less than the second string
+respectively.
+.PP
+\fBTcl_UtfNcasecmp\fR corresponds to \fBstrncasecmp\fR for UTF-8
+strings.  It is similar to \fBTcl_UtfNcmp\fR except comparisons ignore
+differences in case when comparing upper, lower or title case
+characters.
+.PP
+\fBTcl_UtfCharComplete\fR returns 1 if the source UTF-8 string \fIsrc\fR
+of \fIlength\fR bytes is long enough to be decoded by
+\fBTcl_UtfToUniChar\fR, or 0 otherwise.  This function does not guarantee
+that the UTF-8 string is properly formed.  This routine is used by
+procedures that are operating on a byte at a time and need to know if a
+full Tcl_UniChar has been seen.
+.PP
+\fBTcl_NumUtfChars\fR corresponds to \fBstrlen\fR for UTF-8 strings.  It
+returns the number of Tcl_UniChars that are represented by the UTF-8 string
+\fIsrc\fR.  The length of the source string is \fIlength\fR bytes.  If the
+length is negative, all bytes up to the first null byte are used.
+.PP
+\fBTcl_UtfFindFirst\fR corresponds to \fBstrchr\fR for UTF-8 strings.  It
+returns a pointer to the first occurrence of the Tcl_UniChar \fIch\fR
+in the null-terminated UTF-8 string \fIsrc\fR.  The null terminator is
+considered part of the UTF-8 string.  
+.PP
+\fBTcl_UtfFindLast\fR corresponds to \fBstrrchr\fR for UTF-8 strings.  It
+returns a pointer to the last occurrence of the Tcl_UniChar \fIch\fR
+in the null-terminated UTF-8 string \fIsrc\fR.  The null terminator is
+considered part of the UTF-8 string.  
+.PP
+Given \fIsrc\fR, a pointer to some location in a UTF-8 string,
+\fBTcl_UtfNext\fR returns a pointer to the next UTF-8 character in the
+string.  The caller must not ask for the next character after the last
+character in the string if the string is not terminated by a null
+character.
+.PP
+Given \fIsrc\fR, a pointer to some location in a UTF-8 string (or to a
+null byte immediately following such a string), \fBTcl_UtfPrev\fR
+returns a pointer to the closest preceding byte that starts a UTF-8
+character.
+This function will not back up to a position before \fIstart\fR,
+the start of the UTF-8 string.  If \fIsrc\fR was already at \fIstart\fR, the
+return value will be \fIstart\fR.
+.PP
+\fBTcl_UniCharAtIndex\fR corresponds to a C string array dereference or the
+Pascal Ord() function.  It returns the Tcl_UniChar represented at the
+specified character (not byte) \fIindex\fR in the UTF-8 string
+\fIsrc\fR.  The source string must contain at least \fIindex\fR
+characters.  Behavior is undefined if a negative \fIindex\fR is given.
+.PP
+\fBTcl_UtfAtIndex\fR returns a pointer to the specified character (not
+byte) \fIindex\fR in the UTF-8 string \fIsrc\fR.  The source string must
+contain at least \fIindex\fR characters.  This is equivalent to calling 
+\fBTcl_UtfNext\fR \fIindex\fR times.  If a negative \fIindex\fR is given,
+the return pointer points to the first character in the source string.
+.PP
+\fBTcl_UtfBackslash\fR is a utility procedure used by several of the Tcl
+commands.  It parses a backslash sequence and stores the properly formed
+UTF-8 character represented by the backslash sequence in the output
+buffer \fIdst\fR.  At most \fBTCL_UTF_MAX\fR bytes are stored in the buffer.
+\fBTcl_UtfBackslash\fR modifies \fI*readPtr\fR to contain the number
+of bytes in the backslash sequence, including the backslash character.
+The return value is the number of bytes stored in the output buffer.
+.PP
+See the \fBTcl\fR manual entry for information on the valid backslash
+sequences.  All of the sequences described in the Tcl manual entry are
+supported by \fBTcl_UtfBackslash\fR.

+.SH DESCRIPTION
+.PP
+\fBTcl_WrongNumArgs\fR is a utility procedure that is invoked by
+command procedures when they discover that they have received the
+wrong number of arguments.  \fBTcl_WrongNumArgs\fR generates a
+standard error message and stores it in the result value of
+\fIinterp\fR.  The message includes the \fIobjc\fR initial
+elements of \fIobjv\fR plus \fImessage\fR.  For example, if
+\fIobjv\fR consists of the values \fBfoo\fR and \fBbar\fR,
+\fIobjc\fR is 1, and \fImessage\fR is
+.QW "\fBfileName count\fR"
+then \fIinterp\fR's result value will be set to the following
+string:

+.CS

+.CE
+.PP
+If \fIobjc\fR is 2, the result will be set to the following string:
+.PP
+.CS
+wrong # args: should be "foo bar fileName count"
+.CE
+.PP
+\fIObjc\fR is usually 1, but may be 2 or more for commands like
+\fBstring\fR and the Tk widget commands, which use the first argument
+as a subcommand.  
+.PP
+Some of the values in the \fIobjv\fR array may be abbreviations for
+a subcommand.  The command
+\fBTcl_GetIndexFromObj\fR will convert the abbreviated string value
+into an \fIindexObject\fR.  If an error occurs in the parsing of the
+subcommand we would like to use the full subcommand name rather than
+the abbreviation.  If the \fBTcl_WrongNumArgs\fR command finds any
+\fIindexObjects\fR in the \fIobjv\fR array it will use the full subcommand
+name in the error message instead of the abbreviated name that was
+originally passed in.  Using the above example, let us assume that
+\fIbar\fR is actually an abbreviation for \fIbarfly\fR and the value
+is now an \fIindexObject\fR because it was passed to
+\fBTcl_GetIndexFromObj\fR.  In this case the error message would be:

+\fBafter cancel \fIscript script script ...\fR

+.sp
+\fBafter info \fR?\fIid\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command is used to delay execution of the program or to execute
+a command in background sometime in the future.  It has several forms,
+depending on the first argument to the command:
+.TP
+\fBafter \fIms\fR
+.
+\fIMs\fR must be an integer giving a time in milliseconds.
+The command sleeps for \fIms\fR milliseconds and then returns.
+While the command is sleeping the application does not respond to
+events.
+.TP
+\fBafter \fIms \fR?\fIscript script script ...\fR?
+.
+In this form the command returns immediately, but it arranges
+for a Tcl command to be executed \fIms\fR milliseconds later as an
+event handler.
+The command will be executed exactly once, at the given time.
+The delayed command is formed by concatenating all the \fIscript\fR
+arguments in the same fashion as the \fBconcat\fR command.
+The command will be executed at global level (outside the context
+of any Tcl procedure).
+If an error occurs while executing the delayed command then 
+the background error will be reported by the command
+registered with \fBinterp bgerror\fR.
+The \fBafter\fR command returns an identifier that can be used
+to cancel the delayed command using \fBafter cancel\fR.
+.TP
+\fBafter cancel \fIid\fR
+.
+Cancels the execution of a delayed command that
+was previously scheduled.
+\fIId\fR indicates which command should be canceled;  it must have
+been the return value from a previous \fBafter\fR command.
+If the command given by \fIid\fR has already been executed then
+the \fBafter cancel\fR command has no effect.
+.TP
+\fBafter cancel \fIscript script ...\fR
+.
+This command also cancels the execution of a delayed command.
+The \fIscript\fR arguments are concatenated together with space
+separators (just as in the \fBconcat\fR command).
+If there is a pending command that matches the string, it is
+canceled and will never be executed;  if no such command is
+currently pending then the \fBafter cancel\fR command has no effect.
+.TP
+\fBafter idle \fIscript \fR?\fIscript script ...\fR?
+.
+Concatenates the \fIscript\fR arguments together with space
+separators (just as in the \fBconcat\fR command), and arranges
+for the resulting script to be evaluated later as an idle callback.
+The script will be run exactly once, the next time the event
+loop is entered and there are no events to process.
+The command returns an identifier that can be used
+to cancel the delayed command using \fBafter cancel\fR.
+If an error occurs while executing the script then the
+background error will be reported by the command
+registered with \fBinterp bgerror\fR.
+.TP
+\fBafter info \fR?\fIid\fR?
+.
+This command returns information about existing event handlers.
+If no \fIid\fR argument is supplied, the command returns
+a list of the identifiers for all existing
+event handlers created by the \fBafter\fR command for this
+interpreter.
+If \fIid\fR is supplied, it specifies an existing handler;
+\fIid\fR must have been the return value from some previous call
+to \fBafter\fR and it must not have triggered yet or been canceled.
+In this case the command returns a list with two elements.
+The first element of the list is the script associated
+with \fIid\fR, and the second element is either
+\fBidle\fR or \fBtimer\fR to indicate what kind of event
+handler it is.
+.LP
+The \fBafter \fIms\fR and \fBafter idle\fR forms of the command
+assume that the application is event driven:  the delayed commands
+will not be executed unless the application enters the event loop.
+In applications that are not normally event-driven, such as
+\fBtclsh\fR, the event loop can be entered with the \fBvwait\fR
+and \fBupdate\fR commands.
+.SH "EXAMPLES"
+This defines a command to make Tcl do nothing at all for \fIN\fR
+seconds:
+.PP
+.CS
+proc sleep {N} {
+    \fBafter\fR [expr {int($N * 1000)}]
+}
+.CE
+.PP
+This arranges for the command \fIwake_up\fR to be run in eight hours
+(providing the event loop is active at that time):
+.PP
+.CS
+\fBafter\fR [expr {1000 * 60 * 60 * 8}] wake_up
+.CE
+.PP
+The following command can be used to do long-running calculations (as
+represented here by \fI::my_calc::one_step\fR, which is assumed to
+return a boolean indicating whether another step should be performed)
+in a step-by-step fashion, though the calculation itself needs to be
+arranged so it can work step-wise.  This technique is extra careful to
+ensure that the event loop is not starved by the rescheduling of
+processing steps (arranging for the next step to be done using an
+already-triggered timer event only when the event queue has been
+drained) and is useful when you want to ensure that a Tk GUI remains
+responsive during a slow task.
+.PP

+\fBapply \fIfunc\fR ?\fIarg1 arg2 ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+The command \fBapply\fR applies the function \fIfunc\fR to the arguments
+\fIarg1 arg2 ...\fR and returns the result. 
+.PP
+The function \fIfunc\fR is a two element list \fI{args body}\fR or a three
+element list \fI{args body namespace}\fR (as if the
+\fBlist\fR command had been used). 
+The first element \fIargs\fR specifies the formal arguments to
+\fIfunc\fR. The specification of the formal arguments \fIargs\fR
+is shared with the \fBproc\fR command, and is described in detail in the
+corresponding manual page.
+.PP
+The contents of \fIbody\fR are executed by the Tcl interpreter
+after the local variables corresponding to the formal arguments are given
+the values of the actual parameters \fIarg1 arg2 ...\fR.
+When \fIbody\fR is being executed, variable names normally refer to
+local variables, which are created automatically when referenced and
+deleted when \fBapply\fR returns.  One local variable is automatically
+created for each of the function's arguments.
+Global variables can only be accessed by invoking
+the \fBglobal\fR command or the \fBupvar\fR command.
+Namespace variables can only be accessed by invoking
+the \fBvariable\fR command or the \fBupvar\fR command.
+.PP
+The invocation of \fBapply\fR adds a call frame to Tcl's evaluation stack
+(the stack of frames accessed via \fBuplevel\fR). The execution of \fIbody\fR
+proceeds in this call frame, in the namespace given by \fInamespace\fR or
+in the global namespace if none was specified. If given, \fInamespace\fR is
+interpreted relative to the global namespace even if its name does not start
+with
+.QW :: .
+.PP
+The semantics of \fBapply\fR can also be described by:
+.PP
+.CS

+    set len [llength $fun]

+    set code [catch {uplevel 1 $name $args} res opt]
+    return -options $opt $res
+}

+.SH NAME
+array \- Manipulate array variables
+.SH SYNOPSIS
+\fBarray \fIoption arrayName\fR ?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command performs one of several operations on the
+variable given by \fIarrayName\fR.
+Unless otherwise specified for individual commands below,
+\fIarrayName\fR must be the name of an existing array variable.
+The \fIoption\fR argument determines what action is carried
+out by the command.
+The legal \fIoptions\fR (which may be abbreviated) are:
+.TP
+\fBarray anymore \fIarrayName searchId\fR
+Returns 1 if there are any more elements left to be processed
+in an array search, 0 if all elements have already been
+returned.
+\fISearchId\fR indicates which search on \fIarrayName\fR to
+check, and must have been the return value from a previous
+invocation of \fBarray startsearch\fR.
+This option is particularly useful if an array has an element
+with an empty name, since the return value from
+\fBarray nextelement\fR will not indicate whether the search
+has been completed.
+.TP
+\fBarray donesearch \fIarrayName searchId\fR
+This command terminates an array search and destroys all the
+state associated with that search.  \fISearchId\fR indicates
+which search on \fIarrayName\fR to destroy, and must have
+been the return value from a previous invocation of
+\fBarray startsearch\fR.  Returns an empty string.
+.TP
+\fBarray exists \fIarrayName\fR
+Returns 1 if \fIarrayName\fR is an array variable, 0 if there
+is no variable by that name or if it is a scalar variable.
+.TP
+\fBarray get \fIarrayName\fR ?\fIpattern\fR?
+Returns a list containing pairs of elements.  The first
+element in each pair is the name of an element in \fIarrayName\fR
+and the second element of each pair is the value of the
+array element.  The order of the pairs is undefined.
+If \fIpattern\fR is not specified, then all of the elements of the
+array are included in the result.
+If \fIpattern\fR is specified, then only those elements whose names
+match \fIpattern\fR (using the matching rules of
+\fBstring match\fR) are included.
+If \fIarrayName\fR is not the name of an array variable, or if
+the array contains no elements, then an empty list is returned.
+If traces on the array modify the list of elements, the elements
+returned are those that exist both before and after the call to
+\fBarray get\fR.
+.TP
+\fBarray names \fIarrayName\fR ?\fImode\fR? ?\fIpattern\fR?
+Returns a list containing the names of all of the elements in
+the array that match \fIpattern\fR.  \fIMode\fR may be one of
+\fB\-exact\fR, \fB\-glob\fR, or \fB\-regexp\fR.  If specified, \fImode\fR
+designates which matching rules to use to match \fIpattern\fR against
+the names of the elements in the array.  If not specified, \fImode\fR
+defaults to \fB\-glob\fR.  See the documentation for \fBstring match\fR
+for information on glob style matching, and the documentation for
+\fBregexp\fR for information on regexp matching.
+If \fIpattern\fR is omitted then the command returns all of
+the element names in the array.  If there are no (matching) elements
+in the array, or if \fIarrayName\fR is not the name of an array
+variable, then an empty string is returned.
+.TP
+\fBarray nextelement \fIarrayName searchId\fR
+Returns the name of the next element in \fIarrayName\fR, or
+an empty string if all elements of \fIarrayName\fR have
+already been returned in this search.  The \fIsearchId\fR
+argument identifies the search, and must have
+been the return value of an \fBarray startsearch\fR command.
+Warning:  if elements are added to or deleted from the array,
+then all searches are automatically terminated just as if
+\fBarray donesearch\fR had been invoked; this will cause
+\fBarray nextelement\fR operations to fail for those searches.
+.TP
+\fBarray set \fIarrayName list\fR
+Sets the values of one or more elements in \fIarrayName\fR.
+\fIlist\fR must have a form like that returned by \fBarray get\fR,
+consisting of an even number of elements.
+Each odd-numbered element in \fIlist\fR is treated as an element
+name within \fIarrayName\fR, and the following element in \fIlist\fR
+is used as a new value for that array element.
+If the variable \fIarrayName\fR does not already exist
+and \fIlist\fR is empty,
+\fIarrayName\fR is created with an empty array value.
+.TP
+\fBarray size \fIarrayName\fR
+Returns a decimal string giving the number of elements in the
+array.
+If \fIarrayName\fR is not the name of an array then 0 is returned.
+.TP
+\fBarray startsearch \fIarrayName\fR
+This command initializes an element-by-element search through the
+array given by \fIarrayName\fR, such that invocations of the
+\fBarray nextelement\fR command will return the names of the
+individual elements in the array.
+When the search has been completed, the \fBarray donesearch\fR
+command should be invoked.
+The return value is a
+search identifier that must be used in \fBarray nextelement\fR
+and \fBarray donesearch\fR commands; it allows multiple
+searches to be underway simultaneously for the same array.
+It is currently more efficient and easier to use either the \fBarray
+get\fR or \fBarray names\fR, together with \fBforeach\fR, to iterate
+over all but very large arrays.  See the examples below for how to do
+this.
+.TP
+\fBarray statistics \fIarrayName\fR
+Returns statistics about the distribution of data within the hashtable
+that represents the array.  This information includes the number of
+entries in the table, the number of buckets, and the utilization of
+the buckets.
+.TP
+\fBarray unset \fIarrayName\fR ?\fIpattern\fR?
+Unsets all of the elements in the array that match \fIpattern\fR (using the
+matching rules of \fBstring match\fR).  If \fIarrayName\fR is not the name
+of an array variable or there are no matching elements in the array, no
+error will be raised.  If \fIpattern\fR is omitted and \fIarrayName\fR is
+an array variable, then the command unsets the entire array.
+The command always returns an empty string.

+.SH NAME
+bgerror \- Command invoked to process background errors
+.SH SYNOPSIS
+\fBbgerror \fImessage\fR
+.BE
+.SH DESCRIPTION
+.PP
+Release 8.5 of Tcl supports the \fBinterp bgerror\fR command,
+which allows applications to register in an interpreter the command
+that will handle background errors in that interpreter.  In older
+releases of Tcl, this level of control was not available, and applications
+could control the handling of background errors only by creating
+a command with the particular command name \fBbgerror\fR in the
+global namespace of an interpreter.  The following documentation
+describes the interface requirements of the \fBbgerror\fR command
+an application might define to retain compatibility with pre-8.5
+releases of Tcl.  Applications intending to support only
+Tcl releases 8.5 and later should simply make use of \fBinterp bgerror\fR.
+.PP
+The \fBbgerror\fR command does not exist as built-in part of Tcl.  Instead,
+individual applications or users can define a \fBbgerror\fR
+command (e.g. as a Tcl procedure) if they wish to handle background
+errors.
+.PP
+A background error is one that occurs in an event handler or some
+other command that did not originate with the application.
+For example, if an error occurs while executing a command specified
+with the \fBafter\fR command, then it is a background error.
+For a non-background error, the error can simply be returned up
+through nested Tcl command evaluations until it reaches the top-level
+code in the application; then the application can report the error
+in whatever way it wishes.  When a background error occurs, the
+unwinding ends in the Tcl library and there is no obvious way for Tcl
+to report the error.
+.PP
+When Tcl detects a background error, it saves information about the
+error and invokes a handler command registered by \fBinterp bgerror\fR
+later as an idle event handler.  The default handler command in turn
+calls the \fBbgerror\fR command .
+Before invoking \fBbgerror\fR, Tcl restores the
+\fBerrorInfo\fR and \fBerrorCode\fR variables to their values at the
+time the error occurred, then it invokes \fBbgerror\fR with the error
+message as its only argument.  Tcl assumes that the application has
+implemented the \fBbgerror\fR command, and that the command will
+report the error in a way that makes sense for the application.  Tcl
+will ignore any result returned by the \fBbgerror\fR command as long
+as no error is generated.
+.PP
+If another Tcl error occurs within the \fBbgerror\fR command (for
+example, because no \fBbgerror\fR command has been defined) then Tcl
+reports the error itself by writing a message to stderr.
+.PP
+If several background errors accumulate before \fBbgerror\fR is
+invoked to process them, \fBbgerror\fR will be invoked once for each
+error, in the order they occurred.  However, if \fBbgerror\fR returns
+with a break exception, then any remaining errors are skipped without
+calling \fBbgerror\fR.
+.PP
+If you are writing code that will be used by others as part of a
+package or other kind of library, consider avoiding \fBbgerror\fR.
+The reason for this is that the application programmer may also want
+to define a \fBbgerror\fR, or use other code that does and thus will
+have trouble integrating your code.
+.SH "EXAMPLE"
+.PP
+This \fBbgerror\fR procedure appends errors to a file, with a timestamp.
+.PP
+.CS
+proc bgerror {message} {
+    set timestamp [clock format [clock seconds]]

+.SH "BINARY FORMAT"
+.PP
+The \fBbinary format\fR command generates a binary string whose layout
+is specified by the \fIformatString\fR and whose contents come from
+the additional arguments.  The resulting binary value is returned.
+.PP
+The \fIformatString\fR consists of a sequence of zero or more field
+specifiers separated by zero or more spaces.  Each field specifier is
+a single type character followed by an optional flag character followed
+by an optional numeric \fIcount\fR.
+Most field specifiers consume one argument to obtain the value to be
+formatted.  The type character specifies how the value is to be
+formatted.  The \fIcount\fR typically indicates how many items of the
+specified type are taken from the value.  If present, the \fIcount\fR
+is a non-negative decimal integer or \fB*\fR, which normally indicates
+that all of the items in the value are to be used.  If the number of
+arguments does not match the number of fields in the format string
+that consume arguments, then an error is generated. The flag character
+is ignored for \fBbinary format\fR.
+.PP
+Here is a small example to clarify the relation between the field
+specifiers and the arguments:
+.CS
+\fBbinary format\fR d3d {1.0 2.0 3.0 4.0} 0.1
+.CE
+.PP
+The first argument is a list of four numbers, but because of the count
+of 3 for the associated field specifier, only the first three will be
+used. The second argument is associated with the second field
+specifier. The resulting binary string contains the four numbers 1.0,
+2.0, 3.0 and 0.1.
+.PP
+Each type-count pair moves an imaginary cursor through the binary
+data, storing bytes at the current position and advancing the cursor
+to just after the last byte stored.  The cursor is initially at
+position 0 at the beginning of the data.  The type may be any one of
+the following characters:
+.IP \fBa\fR 5
+Stores a byte string of length \fIcount\fR in the output string.
+Every character is taken as modulo 256 (i.e. the low byte of every
+character is used, and the high byte discarded) so when storing
+character strings not wholly expressible using the characters \eu0000-\eu00ff,

+.SH "BINARY SCAN"
+.PP
+The \fBbinary scan\fR command parses fields from a binary string,
+returning the number of conversions performed.  \fIString\fR gives the
+input bytes to be parsed (one byte per character, and characters not
+representable as a byte have their high bits chopped)
+and \fIformatString\fR indicates how to parse it.
+Each \fIvarName\fR gives the name of a variable; when a field is
+scanned from \fIstring\fR the result is assigned to the corresponding
+variable.
+.PP
+As with \fBbinary format\fR, the \fIformatString\fR consists of a
+sequence of zero or more field specifiers separated by zero or more
+spaces.  Each field specifier is a single type character followed by
+an optional flag character followed by an optional numeric \fIcount\fR.
+Most field specifiers consume one
+argument to obtain the variable into which the scanned values should
+be placed.  The type character specifies how the binary data is to be
+interpreted.  The \fIcount\fR typically indicates how many items of
+the specified type are taken from the data.  If present, the
+\fIcount\fR is a non-negative decimal integer or \fB*\fR, which
+normally indicates that all of the remaining items in the data are to
+be used.  If there are not enough bytes left after the current cursor
+position to satisfy the current field specifier, then the
+corresponding variable is left untouched and \fBbinary scan\fR returns
+immediately with the number of variables that were set.  If there are
+not enough arguments for all of the fields in the format string that
+consume arguments, then an error is generated. The flag character
+.QW u
+may be given to cause some types to be read as unsigned values. The flag
+is accepted for all field types but is ignored for non-integer fields.
+.PP
+A similar example as with \fBbinary format\fR should explain the
+relation between field specifiers and arguments in case of the binary
+scan subcommand:
+.CS
+\fBbinary scan\fR $bytes s3s first second
+.CE
+.PP
+This command (provided the binary string in the variable \fIbytes\fR
+is long enough) assigns a list of three integers to the variable
+\fIfirst\fR and assigns a single value to the variable \fIsecond\fR.
+If \fIbytes\fR contains fewer than 8 bytes (i.e. four 2-byte
+integers), no assignment to \fIsecond\fR will be made, and if
+\fIbytes\fR contains fewer than 6 bytes (i.e. three 2-byte integers),
+no assignment to \fIfirst\fR will be made.  Hence:
+.CS
+puts [\fBbinary scan\fR abcdefg s3s first second]
+puts $first
+puts $second
+.CE
+will print (assuming neither variable is set previously):
+.CS
+1
+25185 25699 26213
+can't read "second": no such variable
+.CE
+.PP
+It is \fIimportant\fR to note that the \fBc\fR, \fBs\fR, and \fBS\fR
+(and \fBi\fR and \fBI\fR on 64bit systems) will be scanned into
+long data size values.  In doing this, values that have their high
+bit set (0x80 for chars, 0x8000 for shorts, 0x80000000 for ints),
+will be sign extended.  Thus the following will occur:
+.CS
+set signShort [\fBbinary format\fR s1 0x8000]
+\fBbinary scan\fR $signShort s1 val; \fI# val == 0xFFFF8000\fR
+.CE
+If you require unsigned values you can include the

+flag character following
+the field type. For example, to read an unsigned short value:

+\fBbinary scan\fR $signShort su1 val; \fI# val == 0x00008000\fR

+.SH SYNOPSIS
+\fBbreak\fR
+.BE
+.SH DESCRIPTION
+.PP
+This command is typically invoked inside the body of a looping command
+such as \fBfor\fR or \fBforeach\fR or \fBwhile\fR.
+It returns a 3 (\fBTCL_BREAK\fR) result code, which causes a break exception
+to occur.
+The exception causes the current script to be aborted
+out to the innermost containing loop command, which then
+aborts its execution and returns normally.
+Break exceptions are also handled in a few other situations, such
+as the \fBcatch\fR command, Tk event bindings, and the outermost
+scripts of procedure bodies.
+.SH EXAMPLE
+.PP
+Print a line for each of the integers from 0 to 5:
+.PP
+.CS
+for {set x 0} {$x<10} {incr x} {

+.BE
+
+.SH DESCRIPTION
+.PP
+\fINote: the \fBcase\fI command is obsolete and is supported only
+for backward compatibility.  At some point in the future it may be
+removed entirely.  You should use the \fBswitch\fI command instead.\fR
+.PP
+The \fBcase\fR command matches \fIstring\fR against each of
+the \fIpatList\fR arguments in order.
+Each \fIpatList\fR argument is a list of one or
+more patterns.  If any of these patterns matches \fIstring\fR then
+\fBcase\fR evaluates the following \fIbody\fR argument
+by passing it recursively to the Tcl interpreter and returns the result
+of that evaluation.
+Each \fIpatList\fR argument consists of a single
+pattern or list of patterns.  Each pattern may contain any of the wild-cards
+described under \fBstring match\fR.  If a \fIpatList\fR
+argument is \fBdefault\fR, the corresponding body will be evaluated
+if no \fIpatList\fR matches \fIstring\fR.  If no \fIpatList\fR argument
+matches \fIstring\fR and no default is given, then the \fBcase\fR
+command returns an empty string.
+.PP
+Two syntaxes are provided for the \fIpatList\fR and \fIbody\fR arguments.
+The first uses a separate argument for each of the patterns and commands;
+this form is convenient if substitutions are desired on some of the
+patterns or commands.
+The second form places all of the patterns and commands together into
+a single argument; the argument must have proper list structure, with
+the elements of the list being the patterns and commands.
+The second form makes it easy to construct multi-line case commands,
+since the braces around the whole list make it unnecessary to include a
+backslash at the end of each line.
+Since the \fIpatList\fR arguments are in braces in the second form,
+no command or variable substitutions are performed on them;  this makes
+the behavior of the second form different than the first form in some
+cases.

+.SH NAME
+catch \- Evaluate script and trap exceptional returns
+.SH SYNOPSIS
+\fBcatch\fI script \fR?\fIresultVarName\fR? ?\fIoptionsVarName\fR?
+.BE
+.SH DESCRIPTION
+.PP
+The \fBcatch\fR command may be used to prevent errors from aborting command
+interpretation.  The \fBcatch\fR command calls the Tcl interpreter recursively
+to execute \fIscript\fR, and always returns without raising an error,
+regardless of any errors that might occur while executing \fIscript\fR.
+.PP
+If \fIscript\fR raises an error, \fBcatch\fR will return a non-zero integer
+value corresponding to the exceptional return code returned by evaluation
+of \fIscript\fR.  Tcl defines the normal return code from script
+evaluation to be zero (0), or \fBTCL_OK\fR.  Tcl also defines four exceptional
+return codes: 1 (\fBTCL_ERROR\fR), 2 (\fBTCL_RETURN\fR), 3 (\fBTCL_BREAK\fR),
+and 4 (\fBTCL_CONTINUE\fR).  Errors during evaluation of a script are indicated
+by a return code of \fBTCL_ERROR\fR.  The other exceptional return codes are
+returned by the \fBreturn\fR, \fBbreak\fR, and \fBcontinue\fR commands
+and in other special situations as documented.  Tcl packages can define
+new commands that return other integer values as return codes as well,
+and scripts that make use of the \fBreturn \-code\fR command can also
+have return codes other than the five defined by Tcl.
+.PP
+If the \fIresultVarName\fR argument is given, then the variable it names is
+set to the result of the script evaluation.  When the return code from the
+script is 1 (\fBTCL_ERROR\fR), the value stored in \fIresultVarName\fR is an
+error message.  When the return code from the script is 0 (\fBTCL_OK\fR), the
+value stored in \fIresultVarName\fR is the value returned from \fIscript\fR.
+.PP
+If the \fIoptionsVarName\fR argument is given, then the variable it
+names is set to a dictionary of return options returned by evaluation
+of \fIscript\fR.  Tcl specifies two entries that are always 
+defined in the dictionary: \fB\-code\fR and \fB\-level\fR.  When
+the return code from evaluation of \fIscript\fR is not \fBTCL_RETURN\fR,
+the value of the \fB\-level\fR entry will be 0, and the value
+of the \fB\-code\fR entry will be the same as the return code.
+Only when the return code is \fBTCL_RETURN\fR will the values of
+the \fB\-level\fR and \fB\-code\fR entries be something else, as
+further described in the documentation for the \fBreturn\fR command.
+.PP
+When the return code from evaluation of \fIscript\fR is
+\fBTCL_ERROR\fR, four additional entries are defined in the dictionary
+of return options stored in \fIoptionsVarName\fR: \fB\-errorinfo\fR,
+\fB\-errorcode\fR, \fB\-errorline\fR, and
+.VS 8.6
+\fB\-errorstack\fR.
+.VE 8.6
+The value of the \fB\-errorinfo\fR entry is a formatted stack trace containing
+more information about the context in which the error happened.  The formatted
+stack trace is meant to be read by a person.  The value of the
+\fB\-errorcode\fR entry is additional information about the error stored as a
+list.  The \fB\-errorcode\fR value is meant to be further processed by
+programs, and may not be particularly readable by people.  The value of the
+\fB\-errorline\fR entry is an integer indicating which line of \fIscript\fR
+was being evaluated when the error occurred.
+.VS 8.6
+The value of the \fB\-errorstack\fR entry is an
+even-sized list made of token-parameter pairs accumulated while
+unwinding the stack. The token may be
+.QW \fBCALL\fR ,
+in which case the parameter is a list made of the proc name and arguments at
+the corresponding level; or it may be
+.QW \fBUP\fR ,
+in which case the parameter is
+the relative level (as in \fBuplevel\fR) of the previous \fBCALL\fR. The
+salient differences with respect to \fB\-errorinfo\fR are that:
+.IP [1]
+it is a machine-readable form that is amenable to processing with
+[\fBforeach\fR {tok prm} ...],
+.IP [2]
+it contains the true (substituted) values passed to the functions, instead of
+the static text of the calling sites, and
+.IP [3]
+it is coarser-grained, with only one element per stack frame (like procs; no
+separate elements for \fBforeach\fR constructs for example).
+.VE 8.6
+.PP
+The values of the \fB\-errorinfo\fR and \fB\-errorcode\fR entries of
+the most recent error are also available as values of the global
+variables \fB::errorInfo\fR and \fB::errorCode\fR respectively.
+.VS 8.6
+The value of the \fB\-errorstack\fR entry surfaces as \fBinfo errorstack\fR.
+.VE 8.6
+.PP
+Tcl packages may provide commands that set other entries in the
+dictionary of return options, and the \fBreturn\fR command may be
+used by scripts to set return options in addition to those defined
+above.
+.SH EXAMPLES
+.PP
+The \fBcatch\fR command may be used in an \fBif\fR to branch based on
+the success of a script.
+.PP
+.CS
+if { [\fBcatch\fR {open $someFile w} fid] } {
+    puts stderr "Could not open $someFile for writing\en$fid"

+.SH NAME
+chan \- Read, write and manipulate channels
+.SH SYNOPSIS
+\fBchan \fIoption\fR ?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command provides several operations for reading from, writing to
+and otherwise manipulating open channels (such as have been created
+with the \fBopen\fR and \fBsocket\fR commands, or the default named
+channels \fBstdin\fR, \fBstdout\fR or \fBstderr\fR which correspond to
+the process's standard input, output and error streams respectively).
+\fIOption\fR indicates what to do with the channel; any unique
+abbreviation for \fIoption\fR is acceptable. Valid options are:
+.TP
+\fBchan blocked \fIchannelId\fR
+.
+This tests whether the last input operation on the channel called
+\fIchannelId\fR failed because it would have otherwise caused the
+process to block, and returns 1 if that was the case. It returns 0
+otherwise. Note that this only ever returns 1 when the channel has
+been configured to be non-blocking; all Tcl channels have blocking
+turned on by default.
+.TP
+\fBchan close \fIchannelId\fR ?\fIdirection\fR?
+.
+Close and destroy the channel called \fIchannelId\fR. Note that this
+deletes all existing file-events registered on the channel.
+.VS 8.6
+If the \fIdirection\fR argument (which must be \fBread\fR or \fBwrite\fR or
+any unique abbreviation of them) is present, the channel will only be
+half-closed, so that it can go from being read-write to write-only or
+read-only respectively. If a read-only channel is closed for reading, it is
+the same as if the channel is fully closed, and respectively similar for
+write-only channels. Without the \fIdirection\fR argument, the channel is
+closed for both reading and writing (but only if those directions are
+currently open). It is an error to close a read-only channel for writing, or a
+write-only channel for reading.
+.VE 8.6
+.RS
+.PP
+As part of closing the channel, all buffered output is flushed to the
+channel's output device (only if the channel is ceasing to be writable), any
+buffered input is discarded (only if the channel is ceasing to be readable),
+the underlying operating system resource is closed and \fIchannelId\fR becomes
+unavailable for future use (both only if the channel is being completely
+closed).
+.PP
+If the channel is blocking and the channel is ceasing to be writable, the
+command does not return until all output is flushed.  If the channel is
+non-blocking and there is unflushed output, the channel remains open and the
+command returns immediately; output will be flushed in the background and the
+channel will be closed when all the flushing is complete.
+.PP
+If \fIchannelId\fR is a blocking channel for a command pipeline then
+\fBchan close\fR waits for the child processes to complete.
+.PP
+If the channel is shared between interpreters, then \fBchan close\fR
+makes \fIchannelId\fR unavailable in the invoking interpreter but has
+no other effect until all of the sharing interpreters have closed the
+channel. When the last interpreter in which the channel is registered
+invokes \fBchan close\fR (or \fBclose\fR), the cleanup actions
+described above occur. With half-closing, the half-close of the channel only
+applies to the current interpreter's view of the channel until all channels
+have closed it in that direction (or completely).
+See the \fBinterp\fR command for a description of channel sharing.
+.PP
+Channels are automatically fully closed when an interpreter is destroyed and
+when the process exits.  Channels are switched to blocking mode, to
+ensure that all output is correctly flushed before the process exits.
+.PP
+The command returns an empty string, and may generate an error if
+an error occurs while flushing output.  If a command in a command
+pipeline created with \fBopen\fR returns an error, \fBchan close\fR
+generates an error (similar to the \fBexec\fR command.)
+.PP
+.VS 8.6
+Note that half-closes of sockets and command pipelines can have important side
+effects because they result in a shutdown() or close() of the underlying
+system resource, which can change how other processes or systems respond to
+the Tcl program.
+.VE 8.6
+.RE
+.TP
+\fBchan configure \fIchannelId\fR ?\fIoptionName\fR? ?\fIvalue\fR? ?\fIoptionName value\fR?...

+Query or set the configuration options of the channel named
+\fIchannelId\fR.
+.RS
+.PP
+If no \fIoptionName\fR or \fIvalue\fR arguments are supplied, the
+command returns a list containing alternating option names and values
+for the channel.  If \fIoptionName\fR is supplied but no \fIvalue\fR

+one or more pairs of \fIoptionName\fR and \fIvalue\fR are supplied,
+the command sets each of the named options to the corresponding
+\fIvalue\fR; in this case the return value is an empty string.
+.PP
+The options described below are supported for all channels. In
+addition, each channel type may add options that only it supports. See

+\fB\-blocking\fR \fIboolean\fR

+The \fB\-blocking\fR option determines whether I/O operations on the
+channel can cause the process to block indefinitely.  The value of the
+option must be a proper boolean value.  Channels are normally in
+blocking mode; if a channel is placed into non-blocking mode it will
+affect the operation of the \fBchan gets\fR, \fBchan read\fR, \fBchan
+puts\fR, \fBchan flush\fR, and \fBchan close\fR commands; see the
+documentation for those commands for details.  For non-blocking mode to
+work correctly, the application must be using the Tcl event loop
+(e.g. by calling \fBTcl_DoOneEvent\fR or invoking the \fBvwait\fR
+command).
+.TP
+\fB\-buffering\fR \fInewValue\fR
+.
+If \fInewValue\fR is \fBfull\fR then the I/O system will buffer output
+until its internal buffer is full or until the \fBchan flush\fR
+command is invoked. If \fInewValue\fR is \fBline\fR, then the I/O
+system will automatically flush output for the channel whenever a
+newline character is output. If \fInewValue\fR is \fBnone\fR, the I/O
+system will flush automatically after every output operation.  The
+default is for \fB\-buffering\fR to be set to \fBfull\fR except for
+channels that connect to terminal-like devices; for these channels the
+initial setting is \fBline\fR.  Additionally, \fBstdin\fR and
+\fBstdout\fR are initially set to \fBline\fR, and \fBstderr\fR is set
+to \fBnone\fR.
+.TP
+\fB\-buffersize\fR \fInewSize\fR
+.
+\fINewvalue\fR must be an integer; its value is used to set the size
+of buffers, in bytes, subsequently allocated for this channel to store
+input or output. \fINewvalue\fR must be a number of no more than one
+million, allowing buffers of up to one million bytes in size.
+.TP
+\fB\-encoding\fR \fIname\fR
+.
+This option is used to specify the encoding of the channel as one of
+the named encodings returned by \fBencoding names\fR or the special
+value \fBbinary\fR, so that the data can be converted to and from
+Unicode for use in Tcl.  For instance, in order for Tcl to read
+characters from a Japanese file in \fBshiftjis\fR and properly process
+and display the contents, the encoding would be set to \fBshiftjis\fR.
+Thereafter, when reading from the channel, the bytes in the Japanese
+file would be converted to Unicode as they are read.  Writing is also
+supported \- as Tcl strings are written to the channel they will
+automatically be converted to the specified encoding on output.
+.RS
+.PP
+If a file contains pure binary data (for instance, a JPEG image), the
+encoding for the channel should be configured to be \fBbinary\fR.  Tcl
+will then assign no interpretation to the data in the file and simply
+read or write raw bytes.  The Tcl \fBbinary\fR command can be used to
+manipulate this byte-oriented data.  It is usually better to set the
+\fB\-translation\fR option to \fBbinary\fR when you want to transfer
+binary data, as this turns off the other automatic interpretations of
+the bytes in the stream as well.

+\fB\-eofchar\fR \fB{\fIinChar outChar\fB}\fR
+.
+This option supports DOS file systems that use Control-z (\ex1a) as an
+end of file marker.  If \fIchar\fR is not an empty string, then this
+character signals end-of-file when it is encountered during input.
+For output, the end-of-file character is output when the channel is
+closed.  If \fIchar\fR is the empty string, then there is no special
+end of file character marker.  For read-write channels, a two-element
+list specifies the end of file marker for input and output,
+respectively.  As a convenience, when setting the end-of-file
+character for a read-write channel you can specify a single value that
+will apply to both reading and writing.  When querying the end-of-file
+character of a read-write channel, a two-element list will always be
+returned.  The default value for \fB\-eofchar\fR is the empty string

+\fB\-eofchar\fR is Control-z (\ex1a) for reading and the empty string

+\fB\-translation\fR \fB{\fIinMode outMode\fB}\fR 
+.
+In Tcl scripts the end of a line is always represented using a single
+newline character (\en).  However, in actual files and devices the end
+of a line may be represented differently on different platforms, or
+even for different devices on the same platform.  For example, under
+UNIX newlines are used in files, whereas carriage-return-linefeed
+sequences are normally used in network connections.  On input (i.e.,
+with \fBchan gets\fR and \fBchan read\fR) the Tcl I/O system
+automatically translates the external end-of-line representation into
+newline characters.  Upon output (i.e., with \fBchan puts\fR), the I/O
+system translates newlines to the external end-of-line representation.
+The default translation mode, \fBauto\fR, handles all the common cases
+automatically, but the \fB\-translation\fR option provides explicit
+control over the end of line translations.
+.RS
+.PP
+The value associated with \fB\-translation\fR is a single item for
+read-only and write-only channels.  The value is a two-element list for
+read-write channels; the read translation mode is the first element of
+the list, and the write translation mode is the second element.  As a
+convenience, when setting the translation mode for a read-write channel
+you can specify a single value that will apply to both reading and
+writing.  When querying the translation mode of a read-write channel, a
+two-element list will always be returned.  The following values are
+currently supported:

+\fBauto\fR
+.
+As the input translation mode, \fBauto\fR treats any of newline
+(\fBlf\fR), carriage return (\fBcr\fR), or carriage return followed by
+a newline (\fBcrlf\fR) as the end of line representation.  The end of
+line representation can even change from line-to-line, and all cases
+are translated to a newline.  As the output translation mode,
+\fBauto\fR chooses a platform specific representation; for sockets on
+all platforms Tcl chooses \fBcrlf\fR, for all Unix flavors, it chooses
+\fBlf\fR, and for the various flavors of Windows it chooses
+\fBcrlf\fR.  The default setting for \fB\-translation\fR is \fBauto\fR
+for both input and output.
+.TP
+\fBbinary\fR 
+.
+No end-of-line translations are performed.  This is nearly identical
+to \fBlf\fR mode, except that in addition \fBbinary\fR mode also sets
+the end-of-file character to the empty string (which disables it) and
+sets the encoding to \fBbinary\fR (which disables encoding filtering).
+See the description of \fB\-eofchar\fR and \fB\-encoding\fR for more
+information.
+.TP
+\fBcr\fR
+.
+The end of a line in the underlying file or device is represented by a

+\fBcr\fR mode converts carriage returns to newline characters.  As the
+output translation mode, \fBcr\fR mode translates newline characters
+to carriage returns.
+.TP
+\fBcrlf\fR
+.
+The end of a line in the underlying file or device is represented by a
+carriage return character followed by a linefeed character.  As the

+\fIcallback\fR is called with one or two additional arguments that

+\fBChan copy\fR translates end-of-line sequences in \fIinputChan\fR

+\fBChan copy\fR obeys the encodings and character translations

+A file event handler is a binding between a channel and a script, such

+read as many characters as requested: once all available input has
+been read, the command will return the data that is available rather
+than blocking for more input.  If the channel is configured to use a
+multi-byte encoding, then there may actually be some bytes remaining
+in the internal buffers that do not form a complete character.  These
+bytes will not be returned until a complete character is available or
+end-of-file is reached.  The \fB\-nonewline\fR switch is ignored if
+the command returns before reaching the end of the file.
+.PP
+\fBChan read\fR translates end-of-line sequences in the input into
+newline characters according to the \fB\-translation\fR option for the
+channel (see \fBchan configure\fR above for a discussion on the ways
+in which \fBchan configure\fR will alter input).
+.PP
+When reading from a serial port, most applications should configure
+the serial port channel to be non-blocking, like this:
+.PP
+.CS
+\fBchan configure \fIchannelId \fB\-blocking \fI0\fR.
+.CE
+.PP
+Then \fBchan read\fR behaves much like described above.  Note that
+most serial ports are comparatively slow; it is entirely possible to
+get a \fBreadable\fR event for each character read from them. Care
+must be taken when using \fBchan read\fR on blocking serial ports:
+.TP
+\fBchan read \fIchannelId numChars\fR
+.
+In this form \fBchan read\fR blocks until \fInumChars\fR have been
+received from the serial port.
+.TP
+\fBchan read \fIchannelId\fR
+.
+In this form \fBchan read\fR blocks until the reception of the
+end-of-file character, see \fBchan configure -eofchar\fR. If there no
+end-of-file character has been configured for the channel, then
+\fBchan read\fR will block forever.
+.RE
+.TP
+\fBchan seek \fIchannelId offset\fR ?\fIorigin\fR?
+.
+Sets the current access position within the underlying data stream for
+the channel named \fIchannelId\fR to be \fIoffset\fR bytes relative to
+\fIorigin\fR. \fIOffset\fR must be an integer (which may be negative)
+and \fIorigin\fR must be one of the following:
+.RS
+.TP 10
+\fBstart\fR
+.
+The new access position will be \fIoffset\fR bytes from the start
+of the underlying file or device.
+.TP 10
+\fBcurrent\fR
+.
+The new access position will be \fIoffset\fR bytes from the current
+access position; a negative \fIoffset\fR moves the access position
+backwards in the underlying file or device.
+.TP 10
+\fBend\fR
+.
+The new access position will be \fIoffset\fR bytes from the end of the
+file or device.  A negative \fIoffset\fR places the access position
+before the end of file, and a positive \fIoffset\fR places the access
+position after the end of file.
+.PP
+The \fIorigin\fR argument defaults to \fBstart\fR.
+.PP
+\fBChan seek\fR flushes all buffered output for the channel before the
+command returns, even if the channel is in non-blocking mode.  It also
+discards any buffered and unread input.  This command returns an empty
+string.  An error occurs if this command is applied to channels whose
+underlying file or device does not support seeking.
+.PP
+Note that \fIoffset\fR values are byte offsets, not character offsets.
+Both \fBchan seek\fR and \fBchan tell\fR operate in terms of bytes,
+not characters, unlike \fBchan read\fR.
+.RE
+.TP
+\fBchan tell \fIchannelId\fR
+.
+Returns a number giving the current access position within the
+underlying data stream for the channel named \fIchannelId\fR. This
+value returned is a byte offset that can be passed to \fBchan seek\fR
+in order to set the channel to a particular position.  Note that this
+value is in terms of bytes, not characters like \fBchan read\fR.  The
+value returned is -1 for channels that do not support seeking.
+.TP
+\fBchan truncate \fIchannelId\fR ?\fIlength\fR?
+.
+Sets the byte length of the underlying data stream for the channel
+named \fIchannelId\fR to be \fIlength\fR (or to the current byte
+offset within the underlying data stream if \fIlength\fR is
+omitted). The channel is flushed before truncation.

+.fi
+.SH "CLASS HIERARCHY"
+.nf
+\fBoo::object\fR
+   \(-> \fBoo::class\fR
+.fi
+.BE
+.SH DESCRIPTION
+.PP
+Classes are objects that can manufacture other objects according to a pattern
+stored in the factory object (the class). An instance of the class is created
+by calling one of the class's factory methods, typically either \fBcreate\fR
+if an explicit name is being given, or \fBnew\fR if an arbitrary unique name
+is to be automatically selected.
+.PP
+The \fBoo::class\fR class is the class of all classes; every class is an
+instance of this class, which is consequently an instance of itself. This
+class is a subclass of \fBoo::object\fR, so every class is also an object.
+Additional metaclasses (i.e., classes of classes) can be defined if necessary
+by subclassing \fBoo::class\fR. Note that the \fBoo::class\fR object hides the
+\fBnew\fR method on itself, so new classes should always be made using the
+\fBcreate\fR method.
+.SS CONSTRUCTOR
+.PP
+The constructor of the \fBoo::class\fR class takes an optional argument which,
+if present, is sent to the \fBoo::define\fR command (along with the name of
+the newly-created class) to allow the class to be conveniently configured at
+creation time.
+.SS DESTRUCTOR
+The \fBoo::class\fR class does not define an explicit destructor. However,
+when a class is destroyed, all its subclasses and instances are also
+destroyed, along with all objects that it has been mixed into.
+.SS "EXPORTED METHODS"
+.TP
+\fIcls \fBcreate \fIname \fR?\fIarg ...\fR?
+.
+This creates a new instance of the class \fIcls\fR called \fIname\fR (which is
+resolved within the calling context's namespace if not fully qualified),
+passing the arguments, \fIarg ...\fR, to the constructor, and (if that returns
+a successful result) returning the fully qualified name of the created object
+(the result of the constructor is ignored). If the constructor fails (i.e.
+returns a non-OK result) then the object is destroyed and the error message is
+the result of this method call.
+.TP
+\fIcls \fBnew \fR?\fIarg ...\fR?
+.
+This creates a new instance of the class \fIcls\fR with a new unique name,
+passing the arguments, \fIarg ...\fR, to the constructor, and (if that returns
+a successful result) returning the fully qualified name of the created object
+(the result of the constructor is ignored). If the constructor fails (i.e.,
+returns a non-OK result) then the object is destroyed and the error message is
+the result of this method call.
+.RS
+.PP
+Note that this method is not exported by the \fBoo::class\fR object itself, so
+classes should not be created using this method.
+.RE
+.SS "NON-EXPORTED METHODS"
+.PP
+The \fBoo::class\fR class supports the following non-exported methods:
+.TP
+\fIcls \fBcreateWithNamespace\fI name nsName\fR ?\fIarg ...\fR?
+.
+This creates a new instance of the class \fIcls\fR called \fIname\fR (which is
+resolved within the calling context's namespace if not fully qualified),
+passing the arguments, \fIarg ...\fR, to the constructor, and (if that returns
+a successful result) returning the fully qualified name of the created object
+(the result of the constructor is ignored). The name of the instance's
+internal namespace will be \fInsName\fR unless that namespace already exists
+(when an arbitrary name will be chosen instead). If the constructor fails
+(i.e., returns a non-OK result) then the object is destroyed and the error
+message is the result of this method call.
+.SH EXAMPLES
+.PP
+This example defines a simple class hierarchy and creates a new instance of
+it. It then invokes a method of the object before destroying the hierarchy and
+showing that the destruction is transitive.

+.PP
+The \fBclock\fR command performs several operations that obtain and
+manipulate values that represent times.  The command supports several
+subcommands that determine what action is carried out by the command.
+.TP
+\fBclock add\fR \fItimeVal\fR ?\fIcount unit...\fR? ?\fI\-option value\fR?
+Adds a (possibly negative) offset to a time that is expressed as an
+integer number of seconds.  See \fBCLOCK ARITHMETIC\fR for a full description.
+.TP
+\fBclock clicks\fR ?\fI\-option\fR?
+If no \fI\-option\fR argument is supplied, returns a high-resolution
+time value as a system-dependent integer value.  The unit of the value
+is system-dependent but should be the highest resolution clock available
+on the system such as a CPU cycle counter.  See \fBHIGH RESOLUTION TIMERS\fR for a full description.
+.RS
+.PP
+If the \fI\-option\fR argument is \fB\-milliseconds\fR, then the command

+.TP
+\fBclock seconds\fR 
+Returns the current time as an integer number of seconds.
+.SS "PARAMETERS"
+.TP
+\fIcount\fR
+An integer representing a count of some unit of time.  See
+\fBCLOCK ARITHMETIC\fR for the details.
+.TP
+\fItimeVal\fR
+An integer value passed to the \fBclock\fR command that represents an
+absolute time as a number of seconds from the \fIepoch time\fR of
+1 January 1970, 00:00 UTC.  Note that the count of seconds does not
+include any leap seconds; seconds are counted as if each UTC day has
+exactly 86400 seconds.  Tcl responds to leap seconds by speeding or
+slowing its clock by a tiny fraction for some minutes until it is
+back in sync with UTC; its data model does not represent minutes that
+have 59 or 61 seconds.
+.TP
+\fIunit\fR
+One of the words, \fBseconds\fR, \fBminutes\fR, \fBhours\fR,
+\fBdays\fR, \fBweeks\fR, \fBmonths\fR, or \fByears\fR, or
+any unique prefix of such a word. Used in conjunction with \fIcount\fR
+to identify an interval of time, for example, \fI3 seconds\fR or
+\fI1 year\fR.
+.SS "OPTIONS"
+.TP
+\fB\-base\fR time
+Specifies that any relative times present in a \fBclock scan\fR command
+are to be given relative to \fItime\fR.  \fItime\fR must be expressed as
+a count of nominal seconds from the epoch time of 1 January 1970, 00:00 UTC.
+.TP
+\fB\-format\fR format
+Specifies the desired output format for \fBclock format\fR or the
+expected input format for \fBclock scan\fR.  The \fIformat\fR string consists
+of any number of characters other than the per-cent sign
+.PQ \fB%\fR
+interspersed with any number of \fIformat groups\fR, which are two-character
+sequences beginning with the per-cent sign.  The permissible format groups,
+and their interpretation, are described under \fBFORMAT GROUPS\fR.
+.RS
+.PP
+On \fBclock format\fR, the default format is
+.PP
+.CS
+%a %b %d %H:%M:%S %z %Y
+.CE
+.PP
+On \fBclock scan\fR, the lack of a \fB\-format\fR option indicates that a
+.QW "free format scan"
+is requested; see \fBFREE FORM SCAN\fR for a description of what happens.
+.RE
+.TP
+\fB\-gmt\fR boolean
+If \fIboolean\fR is true, specifies that a time specified to \fBclock add\fR,
+\fBclock format\fR or \fBclock scan\fR should be processed in
+UTC.  If \fIboolean\fR is false, the processing defaults to the local time
+zone.  This usage is obsolete; the correct current usage is to
+specify the UTC time zone with
+.QW "\fB\-timezone\fR \fI:UTC\fR"
+or any of the equivalent ways to specify it.
+.TP
+\fB\-locale\fR localeName
+Specifies that locale-dependent scanning and formatting (and date arithmetic
+for dates preceding the adoption of the Gregorian calendar) is to be done in
+the locale identified by \fIlocaleName\fR.  The locale name may be any of
+the locales acceptable to the \fBmsgcat\fR package, or it may be the special
+name \fIsystem\fR, which represents the current locale of the process, or
+the null string, which represents Tcl's default locale.
+.RS
+.PP
+The effect of locale on scanning and formatting is discussed in the
+descriptions of the individual format groups under \fBFORMAT GROUPS\fR.
+The effect of locale on clock arithmetic is discussed under
+\fBCLOCK ARITHMETIC\fR.
+.RE
+.TP
+\fB\-timezone\fR zoneName
+Specifies that clock arithmetic, formatting, and scanning are to be done
+according to the rules for the time zone specified by \fIzoneName\fR.
+The permissible values, and their interpretation, are discussed under
+\fBTIME ZONES\fR.
+On subcommands that expect a \fB\-timezone\fR argument, the default
+is to use the \fIcurrent time zone\fR.  The current time zone is
+determined, in order of preference, by:
+.RS
+.IP [1]
+the environment variable \fBTCL_TZ\fR.
+.IP [2]
+the environment variable \fBTZ\fR.
+.IP [3]
+on Windows systems, the time zone settings from the Control Panel.
+.RE
+.PP
+If none of these is present, the C \fBlocaltime\fR and \fBmktime\fR
+functions are used to attempt to convert times between local and
+Greenwich.  On 32-bit systems, this approach is likely to have bugs,
+particularly for times that lie outside the window (approximately the
+years 1902 to 2037) that can be represented in a 32-bit integer.
+.SH "CLOCK ARITHMETIC"
+.PP
+The \fBclock add\fR command performs clock arithmetic on a value
+(expressed as nominal seconds from the epoch time of 1 January 1970, 00:00 UTC)
+given as its first argument.  The remaining arguments (other than the
+possible \fB\-timezone\fR, \fB\-locale\fR and \fB\-gmt\fR options)
+are integers and keywords in alternation, where the keywords are chosen
+from \fBseconds\fR, \fBminutes\fR, \fBhours\fR,
+\fBdays\fR, \fBweeks\fR, \fBmonths\fR, or \fByears\fR, or
+any unique prefix of such a word.
+.PP
+Addition of seconds, minutes and hours is fairly straightforward;
+the given time increment (times sixty for minutes, or 3600 for hours)
+is simply added to the \fItimeVal\fR given
+to the \fBclock add\fR command.  The result is interpreted as
+a nominal number of seconds from the Epoch.
+.PP
+Surprising results
+may be obtained when crossing a point at which a leap second is
+inserted or removed; the \fBclock add\fR command simply ignores
+leap seconds and therefore assumes that times come in sequence,
+23:59:58, 23:59:59, 00:00:00.  (This assumption is handled by
+the fact that Tcl's model of time reacts to leap seconds by speeding
+or slowing the clock by a minuscule amount until Tcl's time
+is back in step with the world.
+.PP
+The fact that adding and subtracting hours is defined in terms of
+absolute time means that it will add fixed amounts of time in time zones
+that observe summer time (Daylight Saving Time).  For example,
+the following code sets the value of \fBx\fR to \fB04:00:00\fR because
+the clock has changed in the interval in question.
+.PP
+.CS
+set s [\fBclock scan\fR {2004-10-30 05:00:00} \e

+set x [\fBclock format\fR $a \e
+           -format {%H:%M:%S} -timezone :America/New_York]
+.CE
+.PP
+Adding and subtracting days and weeks is accomplished by converting
+the given time to a calendar day and time of day in the appropriate
+time zone and locale.  The requisite number of days (weeks are converted
+to days by multiplying by seven) is added to the calendar day, and
+the date and time are then converted back to a count of seconds from
+the epoch time.
+.PP
+Adding and subtracting a given number of days across the point that
+the time changes at the start or end of summer time (Daylight Saving Time)
+results in the \fIsame local time\fR on the day in question.  For
+instance, the following code sets the value of \fBx\fR to \fB05:00:00\fR.
+.PP
+.CS
+set s [\fBclock scan\fR {2004-10-30 05:00:00} \e
+           -format {%Y-%m-%d %H:%M:%S} \e
+           -timezone :America/New_York]
+set a [\fBclock add\fR $s 1 day -timezone :America/New_York]
+set x [\fBclock format\fR $a \e
+           -format {%H:%M:%S} -timezone :America/New_York]
+.CE
+.PP
+In cases of ambiguity, where the same local time happens twice
+on the same day, the earlier time is used.  In cases where the conversion
+yields an impossible time (for instance, 02:30 during the Spring
+Daylight Saving Time change using US rules), the time is converted
+as if the clock had not changed.  Thus, the following code
+will set the value of \fBx\fR to \fB03:30:00\fR.
+.PP
+.CS
+set s [\fBclock scan\fR {2004-04-03 02:30:00} \e

+.CE
+.PP
+Adding a given number of days or weeks works correctly across the conversion
+between the Julian and Gregorian calendars; the omitted days are skipped.
+The following code sets \fBz\fR to \fB1752-09-14\fR.
+.PP
+.CS
+set x [\fBclock scan\fR 1752-09-02 -format %Y-%m-%d -locale en_US]
+set y [\fBclock add\fR $x 1 day -locale en_US]
+set z [\fBclock format\fR $y -format %Y-%m-%d -locale en_US]
+.CE
+.PP
+In the bizarre case that adding the given number of days yields a date
+that does not exist because it falls within the dropped days of the
+Julian-to-Gregorian conversion, the date is converted as if it was
+on the Julian calendar.
+.PP
+Adding a number of months, or a number of years, is similar; it
+converts the given time to a calendar date and time of day.  It then
+adds the requisite number of months or years, and reconverts the resulting
+date and time of day to an absolute time.
+.PP
+If the resulting date is impossible because the month has too few days
+(for example, when adding 1 month to 31 January), the last day of the
+month is substituted.  Thus, adding 1 month to 31 January will result in
+28 February in a common year or 29 February in a leap year.
+.PP
+The rules for handling anomalies relating to summer time and to the

+If multiple \fIcount unit\fR pairs are present on the command, they
+are evaluated consecutively, from left to right.
+.SH "HIGH RESOLUTION TIMERS"
+.PP
+Most of the subcommands supported by the \fBclock\fR command deal with
+times represented as a count of seconds from the epoch time, and this is the
+representation that \fBclock seconds\fR returns.  There are three exceptions,
+which are all intended for use where higher-resolution times are required.
+\fBclock milliseconds\fR returns the count of milliseconds from the
+epoch time, and \fBclock microseconds\fR returns the count of microseconds
+from the epoch time. In addition, there is a \fBclock clicks\fR command
+that returns a platform-dependent high-resolution timer.  Unlike
+\fBclock seconds\fR and \fBclock milliseconds\fR, the value
+of \fBclock clicks\fR is not guaranteed to be tied to any fixed
+epoch; it is simply intended to be the most precise interval timer
+available, and is intended only for relative timing studies such as
+benchmarks.
+.SH "FORMATTING TIMES"
+.PP
+The \fBclock format\fR command produces times for display to a user
+or writing to an external medium.  The command accepts times that are
+expressed in seconds from the epoch time of 1 January 1970, 00:00 UTC,
+as returned by \fBclock seconds\fR, \fBclock scan\fR, \fBclock add\fR,
+\fBfile atime\fR or \fBfile mtime\fR.
+.PP
+If a \fB\-format\fR option is present, the following argument is
+a string that specifies how the date and time are to be formatted.
+The string consists
+of any number of characters other than the per-cent sign
+.PQ \fB%\fR
+interspersed with any number of \fIformat groups\fR, which are two-character
+sequences beginning with the per-cent sign.  The permissible format groups,
+and their interpretation, are described under \fBFORMAT GROUPS\fR.
+.PP
+If a \fB\-timezone\fR option is present, the following
+argument is a string that specifies the time zone in which the date and time
+are to be formatted.  As an alternative to
+.QW "\fB\-timezone\fR \fI:UTC\fR" ,
+the obsolete usage
+.QW "\fB\-gmt\fR \fItrue\fR"
+may be used.  See
+\fBTIME ZONES\fR for the permissible variants for the time zone.
+.PP
+If a \fB\-locale\fR option is present, the following argument is
+a string that specifies the locale in which the time is to be formatted,
+in the same format that is used for the \fBmsgcat\fR package.  Note
+that the default, if \fB\-locale\fR is not specified, is the root locale
+\fB{}\fR rather than the current locale.  The current locale may
+be obtained by using \fB\-locale\fR \fBcurrent\fR.
+In addition, some platforms support a \fBsystem\fR locale that
+reflects the user's current choices.  For instance, on Windows, the
+format that the user has selected from dates and times in the Control
+Panel can be obtained by using the \fBsystem\fR locale.  On
+platforms that do not define a user selection of date and time formats
+separate from \fBLC_TIME\fR, \fB\-locale\fR \fBsystem\fR is
+synonymous with \fB\-locale\fR \fBcurrent\fR.
+.SH "SCANNING TIMES"
+.PP
+The \fBclock scan\fR command accepts times that are formatted as
+strings and converts them to counts of seconds from the epoch time
+of 1 January 1970, 00:00 UTC.  It normally takes a \fB\-format\fR
+option that is followed by a string describing
+the expected format of the input.  (See
+\fBFREE FORM SCAN\fR for the effect of \fBclock scan\fR
+without such an argument.)  The string consists of any number of
+characters other than the per-cent sign
+.PQ \fB%\fR "" ,
+interspersed with any number of \fIformat groups\fR, which are two-character
+sequences beginning with the per-cent sign.  The permissible format groups,
+and their interpretation, are described under \fBFORMAT GROUPS\fR.
+.PP
+If a \fB\-timezone\fR option is present, the following
+argument is a string that specifies the time zone in which the date and time
+are to be interpreted.  As an alternative to \fB\-timezone\fR \fI:UTC\fR,
+the obsolete usage \fB\-gmt\fR \fItrue\fR may be used.  See
+\fBTIME ZONES\fR for the permissible variants for the time zone.
+.PP
+If a \fB\-locale\fR option is present, the following argument is
+a string that specifies the locale in which the time is to be interpreted,

+synonymous with \fB\-locale\fR \fBcurrent\fR.
+.PP
+If a \fB\-base\fR option is present, the following argument is
+a time (expressed in seconds from the epoch time) that is used as
+a \fIbase time\fR for interpreting relative times.  If no
+\fB\-base\fR option is present, the base time is the current time.
+.PP
+Scanning of times in fixed format works by determining three things:
+the date, the time of day, and the time zone.  These three are then
+combined into a point in time, which is returned as the number of seconds
+from the epoch.
+.PP
+Before scanning begins, the format string is preprocessed
+to replace \fB%c\fR, \fB%Ec\fR, \fB%x\fR, \fB%Ex\fR,
+\fB%X\fR. \fB%Ex\fR, \fB%r\fR, \fB%R\fR, \fB%T\fR,
+\fB%D\fR, \fB%EY\fR and \fB%+\fR format groups with counterparts
+that are appropriate to the current locale and contain none of the
+above groups.  For instance, \fB%D\fR will (in the \fBen_US\fR locale)
+be replaced with \fB%m/%d/%Y\fR.
+.PP
+The date is determined according to the fields that are present in the
+preprocessed format string.  In order of preference:
+.IP [1]
+If the string contains a \fB%s\fR format group, representing
+seconds from the epoch, that group is used to determine the date.
+.IP [2]
+If the string contains a \fB%J\fR format group, representing
+the Julian Day Number, that group is used to determine the date.
+.IP [3]
+If the string contains a complete set of format groups specifying
+century, year, month, and day of month; century, year, and day of year;
+or ISO8601 fiscal year, week of year, and day of week; those groups are
+combined and used to determine the date.  If more than one complete
+set is present, the one at the rightmost position in the string is
+used.
+.IP [4]
+If the string lacks a century but contains a set of format
+groups specifying year of century, month and day of month; year of
+century and day of year; or two-digit ISO8601 fiscal year, week of year,
+and day of week; those groups are
+combined and used to determine the date.  If more than one complete
+set is present, the one at the rightmost position in the string is
+used.  The year is presumed to lie in the range 1938 to 2037 inclusive.
+.IP [5]
+If the string entirely lacks any specification for the year
+(or contains the year only on the locale's alternative calendar)
+and contains a set of format groups specifying month and day of month,
+day of year, or week of year and day of week, those groups are
+combined and used to determine the date.  If more than one complete
+set is present, the one at the rightmost position in the string is
+used.  The year is determined by interpreting the base time in the given
+time zone.
+.IP [6]
+If the string contains none of the above sets, but has a day
+of the month or day of the week, the day of the month or day of the week
+are used to determine the date by interpreting the base time in the
+given time zone and returning the given day of the current week or month.
+(The week runs from Monday to Sunday, ISO8601-fashion.)  If both day
+of month and day of week are present, the day of the month takes
+priority.
+.IP [7]
+If none of the above rules results in a usable date, the date
+of the base time in the given time zone is used.
+.PP
+The time is also determined according to the fields that are present in the
+preprocessed format string.  In order of preference:
+.IP [1]
+If the string contains a \fB%s\fR format group, representing
+seconds from the epoch, that group determines the time of day.
+.IP [2]
+If the string contains either an hour on the 24-hour clock
+or an hour on the 12-hour clock plus an AM/PM indicator, that hour determines
+the hour of the day.  If the string further contains a group specifying
+the minute of the hour, that group combines with the hour.  If the string
+further contains a group specifying the second of the minute, that group
+combines with the hour and minute.
+.IP [3]
+If the string contains neither a \fB%s\fR format group nor
+a group specifying the hour of the day, then midnight (\fB00:00\fR, the start
+of the given date) is used.
+The time zone is determined by either the \fB\-timezone\fR or \fB\-gmt\fR
+options, or by using the current time zone.
+.PP
+If a format string lacks a \fB%z\fR or \fB%Z\fR format group,
+it is possible for the time to be ambiguous because it appears twice
+in the same day, once without and once with Daylight Saving Time.
+If this situation occurs, the first occurrence of the time is chosen.
+(For this reason, it is wise to have the input string contain the
+time zone when converting local times.  This caveat does not apply to
+UTC times.)
+.SH "FORMAT GROUPS"

+digits.  On input, matches one or two digits, possibly with leading
+whitespace, that are expected to be the number of the day of the month.
+.TP
+\fB%D\fR
+This format group is synonymous with \fB%m/%d/%Y\fR.  It should be

+other locales typically do not use this order for the fields of the date.
+.TP
+\fB%e\fR
+On output, produces the number of the day of the month, as one or
+two decimal digits (with a leading blank for one-digit dates).
+On input, matches one or two digits, possibly with leading
+whitespace, that are expected to be the number of the day of the month.
+.TP
+\fB%Ec\fR
+On output, produces a locale-dependent representation of the date and
+time of day in the locale's alternative calendar.  On input, matches
+whatever \fB%Ec\fR produces.  The locale's alternative calendar need not
+be the Gregorian calendar.
+.TP
+\fB%EC\fR
+On output, produces a locale-dependent name of an era in the locale's
+alternative calendar.  On input, matches the name of the era or any

+to the week number produced by \fB%V\fR.  On input, accepts such
+a two-digit year number, possibly with leading whitespace.
+.TP
+\fB%G\fR
+On output, produces a four-digit year number suitable for use with

+a four-digit year number, possibly with leading whitespace.
+.TP
+\fB%h\fR
+This format group is synonymous with \fB%b\fR.

+.TP
+\fB%p\fR
+On output, produces an indicator for the part of the day, \fBAM\fR
+or \fBPM\fR, appropriate to the given locale.  If the script of the

+\fB%R\fR
+On output, produces a locale-dependent time of day representation on a
+24-hour clock. On input, accepts whatever \fB%R\fR produces.
+.TP
+\fB%s\fR
+On output, simply formats the \fItimeVal\fR argument as a decimal
+integer and inserts it into the output string.  On input, accepts
+a decimal integer and uses is as the time value without any further
+processing. Since \fB%s\fR uniquely determines a point in time, it
+overrides all other input formats.
+.TP
+\fB%S\fR
+On output, produces a two-digit number of the second of the minute
+(00-59). On input, accepts two digits and uses them as the second of the
+minute.
+.TP
+\fB%t\fR
+On output, produces a TAB character. On input, matches a TAB character.
+.TP
+\fB%T\fR
+Synonymous with \fB%H:%M:%S\fR.
+.TP
+\fB%u\fR
+On output, produces the number of the day of the week
+(\fB1\fR\(->Monday, \fB7\fR\(->Sunday). On input, accepts a single digit and

+\fB7\fR.
+.TP
+\fB%U\fR
+On output, produces the ordinal number of the week of the year
+(00-53). The first Sunday of the year is the first day of week 01. On
+input accepts two digits which are otherwise ignored. This format
+group is never used in determining an input date.  This interpretation
+of the week of the year was once common in US banking but is now
+largely obsolete.  See \fB%V\fR for the ISO8601 week number.
+.TP
+\fB%V\fR
+On output, produces the number of the ISO8601 week as a two digit
+number (01-53). Week 01 is the week containing January 4; or the first
+week of the year containing at least 4 days; or the week containing
+the first Thursday of the year (the three statements are
+equivalent). Each week begins on a Monday. On input, accepts the
+ISO8601 week number.
+.TP
+\fB%w\fR
+On output, produces the ordinal number of the day of the week
+(Sunday==0; Saturday==6).  On input, accepts a single digit and
+interprets it as the day of the week; Sunday may be represented as 
+either 0 or 7.  Note that \fB%w\fR is not the ISO8601 weekday number, 
+which is produced and accepted by \fB%u\fR.
+.TP
+\fB%W\fR
+On output, produces a week number (00-53) within the year; week 01
+begins on the first Monday of the year. On input, accepts two digits,

+\fB%X\fR
+On output, produces the time of day in a locale-dependent
+representation. On input, accepts whatever \fB%X\fR produces and is used
+to determine time of day.
+.TP
+\fB%y\fR
+On output, produces the two-digit year of the century. On input,
+accepts two digits, and is used to determine calendar date. The
+date is presumed to lie between 1938 and 2037 inclusive. Note
+that \fB%y\fR does not yield a year appropriate for use with the ISO8601
+week number \fB%V\fR; programs should use \fB%g\fR for that purpose.

+\fB%Y\fR
+On output, produces the four-digit calendar year. On input,
+accepts four digits and may be used to determine calendar date. Note
+that \fB%Y\fR does not yield a year appropriate for use with the ISO8601
+week number \fB%V\fR; programs should use \fB%G\fR for that purpose.

+\fB%z\fR
+On output, produces the current time zone, expressed in hours and

+\fB%Z\fR
+On output, produces the current time zone's name, possibly
+translated to the given locale. On input, accepts a time zone
+specifier (see \fBTIME ZONES\fR below) that will be used to determine the
+time zone. This option should, in general, be used on input only when
+parsing RFC822 dates. Other uses are fraught with ambiguity; for

+summertime takes place each second Sunday in March at 2:00 local
+time, and the switch back is each first Sunday in November at
+3:00 local time. These default rules mean that in all European,
+Russian and US (or compatible) time zones, DST calculations will
+be correct for dates in 2007 and later, unless in the future the
+rules change again.
+.PP
+Any other time zone string is processed by prefixing a colon and attempting
+to use it as a location name, as above.
+.SH "LOCALIZATION"
+.PP
+Developers wishing to localize the date and time formatting and parsing
+are referred to \fIhttp://tip.tcl.tk/173\fR for a
+specification.
+.SH "FREE FORM SCAN"
+.PP
+If the \fBclock scan\fR command is invoked without a \fB\-format\fR
+option, then it requests a \fIfree-form scan.\fR  \fI
+This form of scan is deprecated.\fR  The reason for the deprecation
+is that there are too many ambiguities. (Does the string
+.QW 2000
+represent a year, a time of day, or a quantity?)  No set of rules
+for interpreting free-form dates and times has been found to
+give unsurprising results in all cases.
+.PP
+If free-form scan is used, only the \fB\-base\fR and \fB\-gmt\fR
+options are accepted.  The \fB\-timezone\fR and \fB\-locale\fR
+options will result in an error if \fB\-format\fR is not supplied.
+.PP
+For the benefit of users who need to understand legacy code that
+uses free-form scan, the documentation for how free-form scan
+interprets a string is included here:
+.PP
+If only a time is
+specified, the current date is assumed.  If the \fIinputString\fR
+does not contain a
+time zone mnemonic, the local time zone is assumed, unless the \fB\-gmt\fR
+argument is true, in which case the clock value is calculated assuming
+that the specified time is relative to Greenwich Mean Time.
+\fB\-gmt\fR, if specified, affects only the computed time value; it does not
+impact the interpretation of \fB\-base\fR.
+.PP
+If the \fB\-base\fR flag is specified, the next argument should contain
+an integer clock value.  Only the date in this value is used, not the
+time.  This is useful for determining the time on a specific day or
+doing other date-relative conversions.
+.PP
+The \fIinputString\fR argument consists of zero or more specifications of the
+following form:
+.TP
+\fItime\fR
+A time of day, which is of the form: \fBhh?:mm?:ss?? ?meridian? ?zone?\fR
+or \fBhhmm ?meridian? ?zone?\fR
+If no meridian is specified, \fBhh\fR is interpreted on
+a 24-hour clock.
+.TP
+\fIdate\fR
+A specific month and day with optional year.  The
+acceptable formats are
+.QW "\fBmm/dd\fR?\fB/yy\fR?" ,
+.QW "\fBmonthname dd\fR?\fB, yy\fR?" ,
+.QW "\fBday, dd monthname \fR?\fByy\fR?" ,
+.QW "\fBdd monthname yy\fR" ,
+.QW "?\fBCC\fR?\fByymmdd\fR" ,
+and
+.QW "\fBdd-monthname-\fR?\fBCC\fR?\fByy\fR" .
+The default year is the current year.  If the year is less
+than 100, we treat the years 00-68 as 2000-2068 and the years 69-99
+as 1969-1999.  Not all platforms can represent the years 38-70, so
+an error may result if these years are used.
+.TP
+\fIISO 8601 point-in-time\fR
+An ISO 8601 point-in-time specification, such as
+.QW \fICCyymmdd\fBT\fIhhmmss\fR,
+where \fBT\fR is the literal
+.QW T ,
+.QW "\fICCyymmdd hhmmss\fR" ,
+or
+.QW \fICCyymmdd\fBT\fIhh:mm:ss\fR .
+Note that only these three formats are accepted.
+The command does \fInot\fR accept the full range of point-in-time
+specifications specified in ISO8601.  Other formats can be recognized by
+giving an explicit \fB\-format\fR option to the \fBclock scan\fR command.
+.TP
+\fIrelative time\fR
+A specification relative to the current time.  The format is \fBnumber
+unit\fR. Acceptable units are \fByear\fR, \fBfortnight\fR, 
+\fBmonth\fR, \fBweek\fR, \fBday\fR,
+\fBhour\fR, \fBminute\fR (or \fBmin\fR), and \fBsecond\fR (or \fBsec\fR).  The
+unit can be specified as a singular or plural, as in \fB3 weeks\fR.
+These modifiers may also be specified:
+\fBtomorrow\fR, \fByesterday\fR, \fBtoday\fR, \fBnow\fR,
+\fBlast\fR, \fBthis\fR, \fBnext\fR, \fBago\fR.
+.PP
+The actual date is calculated according to the following steps.
+.PP
+First, any absolute date and/or time is processed and converted.
+Using that time as the base, day-of-week specifications are added.
+Next, relative specifications are used.  If a date or day is
+specified, and no absolute or relative time is given, midnight is
+used.  Finally, a correction is applied so that the correct hour of
+the day is produced after allowing for daylight savings time
+differences and the correct date is given when going from the end
+of a long month to a short month.

+.SH NAME
+close \- Close an open channel
+.SH SYNOPSIS
+\fBclose \fIchannelId\fR ?r(ead)|w(rite)?
+.BE
+.SH DESCRIPTION
+.PP
+Closes or half-closes the channel given by \fIchannelId\fR.
+.PP
+\fIChannelId\fR must be an identifier for an open channel such as a
+Tcl standard channel (\fBstdin\fR, \fBstdout\fR, or \fBstderr\fR),
+the return value from an invocation of \fBopen\fR or \fBsocket\fR, or
+the result of a channel creation command provided by a Tcl extension.
+.PP
+The single-argument form is a simple
+.QW "full-close" :
+all buffered output is flushed to the channel's output device,
+any buffered input is discarded, the underlying file or device is closed,
+and \fIchannelId\fR becomes unavailable for use.
+.PP
+If the channel is blocking, the command does not return until all output
+is flushed.
+If the channel is nonblocking and there is unflushed output, the
+channel remains open and the command
+returns immediately; output will be flushed in the background and the
+channel will be closed when all the flushing is complete.
+.PP
+If \fIchannelId\fR is a blocking channel for a command pipeline then
+\fBclose\fR waits for the child processes to complete.
+.PP
+If the channel is shared between interpreters, then \fBclose\fR
+makes \fIchannelId\fR unavailable in the invoking interpreter but has no
+other effect until all of the sharing interpreters have closed the
+channel.
+When the last interpreter in which the channel is registered invokes
+\fBclose\fR, the cleanup actions described above occur. See the
+\fBinterp\fR command for a description of channel sharing.
+.PP
+Channels are automatically closed when an interpreter is destroyed and
+when the process exits.
+.VS 8.6
+From 8.6 on (TIP#398), nonblocking channels are no longer switched to blocking mode when exiting; this guarantees a timely exit even when the peer or a communication channel is stalled. To ensure proper flushing of stalled nonblocking channels on exit, one must now either (a) actively switch them back to blocking or (b) use the environment variable TCL_FLUSH_NONBLOCKING_ON_EXIT,  which when set and not equal to "0" restores the previous behavior.
+.VE 8.6
+.PP
+The command returns an empty string, and may generate an error if
+an error occurs while flushing output.  If a command in a command
+pipeline created with \fBopen\fR returns an error, \fBclose\fR
+generates an error (similar to the \fBexec\fR command.)
+.PP
+.VS 8.6
+The two-argument form is a
+.QW "half-close" :
+given a bidirectional channel like a
+socket or command pipeline and a (possibly abbreviated) direction, it closes
+only the sub-stream going in that direction. This means a shutdown() on a
+socket, and a close() of one end of a pipe for a command pipeline. Then, the
+Tcl-level channel data structure is either kept or freed depending on whether
+the other direction is still open.
+.PP
+A single-argument close on an already half-closed bidirectional channel is
+defined to just
+.QW "finish the job" .
+A half-close on an already closed half, or on a wrong-sided unidirectional
+channel, raises an error.
+.PP
+In the case of a command pipeline, the child-reaping duty falls upon the
+shoulders of the last close or half-close, which is thus allowed to report an
+abnormal exit error.
+.PP
+Currently only sockets and command pipelines support half-close. A future
+extension will allow reflected and stacked channels to do so.
+.VE 8.6
+.SH EXAMPLE
+.PP
+This illustrates how you can use Tcl to ensure that files get closed
+even when errors happen by combining \fBcatch\fR, \fBclose\fR and
+\fBreturn\fR:
+.PP
+.CS
+proc withOpenFile {filename channelVar script} {
+    upvar 1 $channelVar chan
+    set chan [open $filename]
+    catch {
+        uplevel 1 $script

+.SH DESCRIPTION
+.PP
+This command joins each of its arguments together with spaces after

+arguments are lists, this has the same effect as concatenating them
+into a single list.
+It permits any number of arguments;
+if no \fIarg\fRs are supplied, the result is an empty string.
+.SH EXAMPLES
+Although \fBconcat\fR will concatenate lists, flattening them in the process

+.PP
+.CS
+\fI%\fR \fBconcat\fR a b {c d e} {f {g h}}

+.PP
+.CS
+\fI%\fR \fBconcat\fR " a b {c   " d "  e} f"

+.CE
+.PP
+Note also that the concatenation does not remove spaces from the middle of

+.SH DESCRIPTION
+.PP
+The \fBoo::copy\fR command creates a copy of an object or class. It takes the
+name of the object or class to be copied, \fIsourceObject\fR, and optionally
+the name of the object or class to create, \fItargetObject\fR, which will be
+resolved relative to the current namespace if not an absolute qualified name.
+If \fItargetObject\fR is omitted, a new name is chosen. The copied object will
+be of the same class as the source object, and will have all its per-object
+methods copied. If it is a class, it will also have all the class methods in
+the class copied, but it will not have any of its instances copied.
+.PP
+.VS
+After the \fItargetObject\fR has been created and all definitions of its
+configuration (e.g., methods, filters, mixins) copied, the \fB<cloned>\fR
+method of \fItargetObject\fR will be invoked, to allow for customization of
+the created object such as installing related variable traces. The only
+argument given will be \fIsourceObject\fR. The default implementation of this
+method (in \fBoo::object\fR) just copies the procedures and variables in the
+namespace of \fIsourceObject\fR to the namespace of \fItargetObject\fR. If
+this method call does not return a result that is successful (i.e., an error
+or other kind of exception) then the \fItargetObject\fR will be deleted and an
+error returned.

+.VE TIP396
+.fi
+.BE
+.SH DESCRIPTION
+.PP
+The \fBcoroutine\fR command creates a new coroutine context (with associated
+command) named \fIname\fR and executes that context by calling \fIcommand\fR,
+passing in the other remaining arguments without further interpretation. Once
+\fIcommand\fR returns normally or with an exception (e.g., an error) the
+coroutine context \fIname\fR is deleted.
+.PP
+Within the context, values may be generated as results by using the
+\fByield\fR command; if no \fIvalue\fR is supplied, the empty string is used.
+When that is called, the context will suspend execution and the
+\fBcoroutine\fR command will return the argument to \fByield\fR. The execution
+of the context can then be resumed by calling the context command, optionally
+passing in the \fIsingle\fR value to use as the result of the \fByield\fR call
+that caused
+the context to be suspended. If the coroutine context never yields and instead
+returns conventionally, the result of the \fBcoroutine\fR command will be the
+result of the evaluation of the context.
+.PP
+.VS TIP396
+The coroutine may also suspend its execution by use of the \fByieldto\fR
+command, which instead of returning, cedes execution to some command called
+\fIcommand\fR (resolved in the context of the coroutine) and to which \fIany
+number\fR of arguments may be passed. Since every coroutine has a context
+command, \fByieldto\fR can be used to transfer control directly from one
+coroutine to another (this is only advisable if the two coroutines are
+expecting this to happen) but \fIany\fR command may be the target. If a
+coroutine is suspended by this mechanism, the coroutine processing can be
+resumed by calling the context command optionally passing in an arbitrary
+number of arguments. The return value of the \fByieldto\fR call will be the
+list of arguments passed to the context command; it is up to the caller to
+decide what to do with those values.
+.PP
+The recommended way of writing a version of \fByield\fR that allows resumption
+with multiple arguments is by using \fByieldto\fR and the \fBreturn\fR
+command, like this:
+.PP
+.CS
+proc yieldm {value} {
+    \fByieldto\fR return -level 0 $value
+}
+.CE
+.VE TIP396
+.PP
+The coroutine can also be deleted by destroying the command \fIname\fR, and
+the name of the current coroutine can be retrieved by using
+\fBinfo coroutine\fR.
+If there are deletion traces on variables in the coroutine's
+implementation, they will fire at the point when the coroutine is explicitly
+deleted (or, naturally, if the command returns conventionally).
+.PP
+At the point when \fIcommand\fR is called, the current namespace will be the
+global namespace and there will be no stack frames above it (in the sense of
+\fBupvar\fR and \fBuplevel\fR). However, which command to call will be
+determined in the namespace that the \fBcoroutine\fR command was called from.
+.SH EXAMPLES
+.PP
+This example shows a coroutine that will produce an infinite sequence of
+even values, and a loop that consumes the first ten of them.

+.SH DESCRIPTION
+.PP
+This command allows an application to send Dynamic Data Exchange (DDE)
+command when running under Microsoft Windows. Dynamic Data Exchange is
+a mechanism where applications can exchange raw data. Each DDE
+transaction needs a \fIservice name\fR and a \fItopic\fR. Both the
+\fIservice name\fR and \fItopic\fR are application defined; Tcl uses
+the service name \fBTclEval\fR, while the topic name is the name of the
+interpreter given by \fBdde servername\fR. Other applications have their
+own \fIservice names\fR and \fItopics\fR. For instance, Microsoft Excel
+has the service name \fBExcel\fR.
+.PP
+.SH "DDE COMMANDS"
+.PP
+The following commands are a subset of the full Dynamic Data Exchange
+set of commands.
+.TP
+\fBdde servername \fR?\fB\-force\fR? ?\fB\-handler \fIproc\fR? ?\fB\-\|\-\fR? ?\fItopic\fR?
+.
+\fBdde servername\fR registers the interpreter as a DDE server with
+the service name \fBTclEval\fR and the topic name specified by \fItopic\fR.
+If no \fItopic\fR is given, \fBdde servername\fR returns the name
+of the current topic or the empty string if it is not registered as a
+service. If the given \fItopic\fR name is already in use, then a
+suffix of the form
+.QW " #2"
+or
+.QW " #3"
+is appended to the name to make it
+unique. The command's result will be the name actually used. The
+\fB\-force\fR option is used to force registration of precisely the
+given \fItopic\fR name.
+.RS
+.PP
+The \fB\-handler\fR option specifies a Tcl procedure that will be called to
+process calls to the dde server. If the package has been loaded into a
+safe interpreter then a \fB\-handler\fR procedure must be defined. The
+procedure is called with all the arguments provided by the remote
+call.
+.RE
+.TP
+\fBdde execute\fR ?\fB\-async\fR? ?\fB\-binary\fR? \fIservice topic data\fR
+.
+\fBdde execute\fR takes the \fIdata\fR and sends it to the server indicated
+by \fIservice\fR with the topic indicated by \fItopic\fR. Typically,
+\fIservice\fR is the name of an application, and \fItopic\fR is a file to
+work on.  The \fIdata\fR field is given to the remote application.
+Typically, the application treats the \fIdata\fR field as a script, and the
+script is run in the application.  The \fB\-async\fR option requests
+asynchronous invocation.  The command returns an error message if the
+script did not run, unless the \fB\-async\fR flag was used, in which case
+the command returns immediately with no error.
+.VS 8.6
+Without the \fB\-binary\fR option all data will be sent in unicode. For
+dde clients which don't implement the CF_UNICODE clipboard format, this
+will automatically be translated to the system encoding. You can use 
+the \fB\-binary\fR option in combination with the result of
+\fBencoding convertto\fR to send data in any other encoding.
+.VE 8.6
+.TP
+\fBdde poke\fR ?\fB\-binary\fR? \fIservice topic item data\fR
+.
+\fBdde poke\fR passes the \fIdata\fR to the server indicated by
+\fIservice\fR using the \fItopic\fR and \fIitem\fR specified.  Typically,
+\fIservice\fR is the name of an application.  \fItopic\fR is application
+specific but can be a command to the server or the name of a file to work
+on.  The \fIitem\fR is also application specific and is often not used, but
+it must always be non-null.  The \fIdata\fR field is given to the remote
+application.
+.VS 8.6
+Without the \fB\-binary\fR option all data will be sent in unicode. For
+dde clients which don't implement the CF_UNICODE clipboard format, this
+will automatically be translated to the system encoding. You can use 
+the \fB\-binary\fR option in combination with the result of
+\fBencoding convertto\fR to send data in any other encoding.
+.VE 8.6
+.TP
+\fBdde request\fR ?\fB\-binary\fR? \fIservice topic item\fR
+.
+\fBdde request\fR is typically used to get the value of something; the
+value of a cell in Microsoft Excel or the text of a selection in
+Microsoft Word. \fIservice\fR is typically the name of an application,
+\fItopic\fR is typically the name of the file, and \fIitem\fR is
+application-specific. The command returns the value of \fIitem\fR as
+defined in the application.  Normally this is interpreted to be a
+string with terminating null.  If \fB\-binary\fR is specified, the
+result is returned as a byte array.
+.TP
+\fBdde services \fIservice topic\fR
+.
+\fBdde services\fR returns a list of service-topic pairs that
+currently exist on the machine. If \fIservice\fR and \fItopic\fR are
+both empty strings ({}), then all service-topic pairs currently
+available on the system are returned. If \fIservice\fR is empty and
+\fItopic\fR is not, then all services with the specified topic are
+returned. If \fIservice\fR is non-empty and \fItopic\fR is, all topics
+for a given service are returned. If both are non-empty, if that
+service-topic pair currently exists, it is returned; otherwise, an
+empty string is returned.
+.TP
+\fBdde eval\fR ?\fB\-async\fR? \fItopic cmd \fR?\fIarg arg ...\fR?
+.
+\fBdde eval\fR evaluates a command and its arguments using the interpreter
+specified by \fItopic\fR. The DDE service must be the \fBTclEval\fR
+service.  The \fB\-async\fR option requests asynchronous invocation.  The
+command returns an error message if the script did not run, unless the
+\fB\-async\fR flag was used, in which case the command returns immediately
+with no error.  This command can be used to replace send on Windows.
+.SH "DDE AND TCL"
+.PP
+A Tcl interpreter always has a service name of \fBTclEval\fR.  Each
+different interpreter of all running Tcl applications must be
+given a unique
+name specified by \fBdde servername\fR. Each interp is available as a
+DDE topic only if the \fBdde servername\fR command was used to set the
+name of the topic for each interp. So a \fBdde services TclEval {}\fR
+command will return a list of service-topic pairs, where each of the
+currently running interps will be a topic.
+.PP
+When Tcl processes a \fBdde execute\fR command, the data for the
+execute is run as a script in the interp named by the topic of the
+\fBdde execute\fR command.
+.PP
+When Tcl processes a \fBdde request\fR command, it returns the value of the
+variable given in the dde command in the context of the interp named by the
+dde topic. Tcl reserves the variable \fB$TCLEVAL$EXECUTE$RESULT\fR for
+internal use, and \fBdde request\fR commands for that variable will give
+unpredictable results.
+.PP
+An external application which wishes to run a script in Tcl should have
+that script store its result in a variable, run the \fBdde execute\fR
+command, and then run \fBdde request\fR to get the value of the
+variable.
+.PP
+When using DDE, be careful to ensure that the event queue is flushed
+using either \fBupdate\fR or \fBvwait\fR.  This happens by default
+when using \fBwish\fR unless a blocking command is called (such as \fBexec\fR
+without adding the \fB&\fR to place the process in the background).
+If for any reason the event queue is not flushed, DDE commands may
+hang until the event queue is flushed.  This can create a deadlock
+situation.

+.nf
+package require TclOO

+\fBoo::define\fI class defScript\fR
+\fBoo::define\fI class subcommand arg\fR ?\fIarg ...\fR?
+\fBoo::objdefine\fI object defScript\fR
+\fBoo::objdefine\fI object subcommand arg\fR ?\fIarg ...\fR?
+.fi
+.BE
+
+.SH DESCRIPTION
+The \fBoo::define\fR command is used to control the configuration of classes,
+and the \fBoo::objdefine\fR command is used to control the configuration of
+objects (including classes as instance objects), with the configuration being
+applied to the entity named in the \fIclass\fR or the \fIobject\fR argument.
+Configuring a class also updates the
+configuration of all subclasses of the class and all objects that are
+instances of that class or which mix it in (as modified by any per-instance
+configuration). The way in which the configuration is done is controlled by
+either the \fIdefScript\fR argument or by the \fIsubcommand\fR and following
+\fIarg\fR arguments; when the second is present, it is exactly as if all the
+arguments from \fIsubcommand\fR onwards are made into a list and that list is
+used as the \fIdefScript\fR argument.
+.SS "CONFIGURING CLASSES"
+.PP
+The following commands are supported in the \fIdefScript\fR for
+\fBoo::define\fR, each of which may also be used in the \fIsubcommand\fR form:
+.TP
+\fBconstructor\fI argList bodyScript\fR
+.
+This creates or updates the constructor for a class. The formal arguments to
+the constructor (defined using the same format as for the Tcl \fBproc\fR
+command) will be \fIargList\fR, and the body of the constructor will be
+\fIbodyScript\fR. When the body of the constructor is evaluated, the current
+namespace of the constructor will be a namespace that is unique to the object
+being constructed. Within the constructor, the \fBnext\fR command should be
+used to call the superclasses' constructors. If \fIbodyScript\fR is the empty
+string, the constructor will be deleted.
+.TP
+\fBdeletemethod\fI name\fR ?\fIname ...\fR
+.
+This deletes each of the methods called \fIname\fR from a class. The methods
+must have previously existed in that class. Does not affect the superclasses
+of the class, nor does it affect the subclasses or instances of the class
+(except when they have a call chain through the class being modified).
+.TP
+\fBdestructor\fI bodyScript\fR
+.
+This creates or updates the destructor for a class. Destructors take no
+arguments, and the body of the destructor will be \fIbodyScript\fR. The
+destructor is called when objects of the class are deleted, and when called
+will have the object's unique namespace as the current namespace. Destructors
+should use the \fBnext\fR command to call the superclasses' destructors. Note
+that destructors are not called in all situations (e.g. if the interpreter is
+destroyed). If \fIbodyScript\fR is the empty string, the destructor will be
+deleted.
+.RS
+Note that errors during the evaluation of a destructor \fIare not returned\fR
+to the code that causes the destruction of an object. Instead, they are passed
+to the currently-defined \fBbgerror\fR handler.
+.RE
+.TP
+\fBexport\fI name \fR?\fIname ...\fR?
+.
+This arranges for each of the named methods, \fIname\fR, to be exported
+(i.e. usable outside an instance through the instance object's command) by the
+class being defined. Note that the methods themselves may be actually defined
+by a superclass; subclass exports override superclass visibility, and may in
+turn be overridden by instances.
+.TP
+\fBfilter\fR ?\fI\-slotOperation\fR? ?\fImethodName ...\fR?
+.VS
+This slot (see \fBSLOTTED DEFINITIONS\fR below)
+.VE
+sets or updates the list of method names that are used to guard whether
+method call to instances of the class may be called and what the method's
+results are. Each \fImethodName\fR names a single filtering method (which may
+be exposed or not exposed); it is not an error for a non-existent method to be
+named since they may be defined by subclasses.
+.VS
+By default, this slot works by appending.
+.VE
+.TP
+\fBforward\fI name cmdName \fR?\fIarg ...\fR?
+.
+This creates or updates a forwarded method called \fIname\fR. The method is
+defined be forwarded to the command called \fIcmdName\fR, with additional
+arguments, \fIarg\fR etc., added before those arguments specified by the
+caller of the method. The \fIcmdName\fR will always be resolved using the
+rules of the invoking objects' namespaces, i.e., when \fIcmdName\fR is not
+fully-qualified, the command will be searched for in each object's namespace,
+using the instances' namespace's path, or by looking in the global namespace.
+The method will be exported if \fIname\fR starts with a lower-case letter, and
+non-exported otherwise.
+.TP
+\fBmethod\fI name argList bodyScript\fR
+.
+This creates or updates a method that is implemented as a procedure-like
+script. The name of the method is \fIname\fR, the formal arguments to the
+method (defined using the same format as for the Tcl \fBproc\fR command) will
+be \fIargList\fR, and the body of the method will be \fIbodyScript\fR. When
+the body of the method is evaluated, the current namespace of the method will
+be a namespace that is unique to the current object. The method will be
+exported if \fIname\fR starts with a lower-case letter, and non-exported
+otherwise; this behavior can be overridden via \fBexport\fR and
+\fBunexport\fR.
+.TP
+\fBmixin\fR ?\fI\-slotOperation\fR? ?\fIclassName ...\fR?
+.VS
+This slot (see \fBSLOTTED DEFINITIONS\fR below)
+.VE
+sets or updates the list of additional classes that are to be mixed into
+all the instances of the class being defined. Each \fIclassName\fR argument
+names a single class that is to be mixed in.
+.VS
+By default, this slot works by replacement.
+.VE
+.TP
+\fBrenamemethod\fI fromName toName\fR
+.
+This renames the method called \fIfromName\fR in a class to \fItoName\fR. The
+method must have previously existed in the class, and \fItoName\fR must not
+previously refer to a method in that class. Does not affect the superclasses
+of the class, nor does it affect the subclasses or instances of the class
+(except when they have a call chain through the class being modified). Does
+not change the export status of the method; if it was exported before, it will
+be afterwards.
+.TP
+\fBself\fI subcommand arg ...\fR
+.TP
+\fBself\fI script\fR
+.
+This command is equivalent to calling \fBoo::objdefine\fR on the class being
+defined (see \fBCONFIGURING OBJECTS\fR below for a description of the
+supported values of \fIsubcommand\fR). It follows the same general pattern of
+argument handling as the \fBoo::define\fR and \fBoo::objdefine\fR commands,
+and
+.QW "\fBoo::define \fIcls \fBself \fIsubcommand ...\fR"
+operates identically to
+.QW "\fBoo::objdefine \fIcls subcommand ...\fR" .
+.TP
+\fBsuperclass\fR ?\fI\-slotOperation\fR? ?\fIclassName ...\fR?
+.VS
+This slot (see \fBSLOTTED DEFINITIONS\fR below)
+.VE
+allows the alteration of the superclasses of the class being defined.
+Each \fIclassName\fR argument names one class that is to be a superclass of
+the defined class. Note that objects must not be changed from being classes to
+being non-classes or vice-versa, that an empty parent class is equivalent to
+\fBoo::object\fR, and that the parent classes of \fBoo::object\fR and
+\fBoo::class\fR may not be modified.
+.VS
+By default, this slot works by replacement.
+.VE
+.TP
+\fBunexport\fI name \fR?\fIname ...\fR?
+.
+This arranges for each of the named methods, \fIname\fR, to be not exported
+(i.e. not usable outside the instance through the instance object's command,
+but instead just through the \fBmy\fR command visible in each object's
+context) by the class being defined. Note that the methods themselves may be
+actually defined by a superclass; subclass unexports override superclass
+visibility, and may be overridden by instance unexports.
+.TP
+\fBvariable\fR ?\fI\-slotOperation\fR? ?\fIname ...\fR?
+.VS
+This slot (see \fBSLOTTED DEFINITIONS\fR below) arranges for each of the named
+variables to be automatically made
+available in the methods, constructor and destructor declared by the class
+being defined. Each variable name must not have any namespace
+separators and must not look like an array access. All variables will be
+actually present in the instance object on which the method is executed. Note
+that the variable lists declared by a superclass or subclass are completely
+disjoint, as are variable lists declared by instances; the list of variable
+names is just for methods (and constructors and destructors) declared by this
+class. By default, this slot works by appending.
+.VE
+.SS "CONFIGURING OBJECTS"
+.PP
+The following commands are supported in the \fIdefScript\fR for
+\fBoo::objdefine\fR, each of which may also be used in the \fIsubcommand\fR
+form:
+.TP
+\fBclass\fI className\fR
+.
+This allows the class of an object to be changed after creation. Note that the
+class's constructors are not called when this is done, and so the object may
+well be in an inconsistent state unless additional configuration work is done.
+.TP
+\fBdeletemethod\fI name\fR ?\fIname ...\fR
+.
+This deletes each of the methods called \fIname\fR from an object. The methods
+must have previously existed in that object. Does not affect the classes that
+the object is an instance of.
+.TP
+\fBexport\fI name \fR?\fIname ...\fR?
+.
+This arranges for each of the named methods, \fIname\fR, to be exported
+(i.e. usable outside the object through the object's command) by the object
+being defined. Note that the methods themselves may be actually defined by a
+class or superclass; object exports override class visibility.
+.TP
+\fBfilter\fR ?\fI\-slotOperation\fR? ?\fImethodName ...\fR?
+.VS
+This slot (see \fBSLOTTED DEFINITIONS\fR below)
+.VE
+sets or updates the list of method names that are used to guard whether a
+method call to the object may be called and what the method's results are.
+Each \fImethodName\fR names a single filtering method (which may be exposed or
+not exposed); it is not an error for a non-existent method to be named. Note
+that the actual list of filters also depends on the filters set upon any
+classes that the object is an instance of.
+.VS
+By default, this slot works by appending.
+.VE
+.TP
+\fBforward\fI name cmdName \fR?\fIarg ...\fR?
+.
+This creates or updates a forwarded object method called \fIname\fR. The
+method is defined be forwarded to the command called \fIcmdName\fR, with
+additional arguments, \fIarg\fR etc., added before those arguments specified
+by the caller of the method. Forwarded methods should be deleted using the
+\fBmethod\fR subcommand. The method will be exported if \fIname\fR starts with
+a lower-case letter, and non-exported otherwise.
+.TP
+\fBmethod\fI name argList bodyScript\fR
+.
+This creates, updates or deletes an object method. The name of the method is
+\fIname\fR, the formal arguments to the method (defined using the same format
+as for the Tcl \fBproc\fR command) will be \fIargList\fR, and the body of the
+method will be \fIbodyScript\fR. When the body of the method is evaluated, the
+current namespace of the method will be a namespace that is unique to the
+object. The method will be exported if \fIname\fR starts with a lower-case
+letter, and non-exported otherwise.
+.TP
+\fBmixin\fR ?\fI\-slotOperation\fR? ?\fIclassName ...\fR?
+.VS
+This slot (see \fBSLOTTED DEFINITIONS\fR below)
+.VE
+sets or updates a per-object list of additional classes that are to be
+mixed into the object. Each argument, \fIclassName\fR, names a single class
+that is to be mixed in.
+.VS
+By default, this slot works by replacement.
+.VE
+.TP
+\fBrenamemethod\fI fromName toName\fR
+.
+This renames the method called \fIfromName\fR in an object to \fItoName\fR.
+The method must have previously existed in the object, and \fItoName\fR must
+not previously refer to a method in that object. Does not affect the classes
+that the object is an instance of. Does not change the export status of the
+method; if it was exported before, it will be afterwards.
+.TP
+\fBunexport\fI name \fR?\fIname ...\fR?
+.
+This arranges for each of the named methods, \fIname\fR, to be not exported
+(i.e. not usable outside the object through the object's command, but instead
+just through the \fBmy\fR command visible in the object's context) by the
+object being defined. Note that the methods themselves may be actually defined
+by a class; instance unexports override class visibility.
+.TP
+\fBvariable\fR ?\fI\-slotOperation\fR? ?\fIname ...\fR?
+.VS
+This slot (see \fBSLOTTED DEFINITIONS\fR below) arranges for each of the named
+variables to be automatically made available in the methods declared by the
+object being defined.  Each variable name must not have any namespace
+separators and must not look like an array access. All variables will be
+actually present in the object on which the method is executed. Note that the
+variable lists declared by the classes and mixins of which the object is an
+instance are completely disjoint; the list of variable names is just for
+methods declared by this object. By default, this slot works by appending.
+.SH "SLOTTED DEFINITIONS"
+Some of the configurable definitions of a class or object are \fIslotted
+definitions\fR. This means that the configuration is implemented by a slot
+object, that is an instance of the class \fBoo::Slot\fR, which manages a list
+of values (class names, variable names, etc.) that comprises the contents of
+the slot. The class defines three operations (as methods) that may be done on
+the slot:
+.VE
+.TP
+\fIslot\fR \fB\-append\fR ?\fImember ...\fR?
+.VS
+This appends the given \fImember\fR elements to the slot definition.
+.VE
+.TP
+\fIslot\fR \fB\-clear\fR
+.VS
+This sets the slot definition to the empty list.
+.VE
+.TP
+\fIslot\fR \fB\-set\fR ?\fImember ...\fR?
+.VS
+This replaces the slot definition with the given \fImember\fR elements.
+.PP
+A consequence of this is that any use of a slot's default operation where the
+first member argument begins with a hyphen will be an error. One of the above
+operations should be used explicitly in those circumstances.
+.SS "SLOT IMPLEMENTATION"
+Internally, slot objects also define a method \fB\-\-default\-operation\fR
+which is forwarded to the default operation of the slot (thus, for the class
+.QW \fBvariable\fR
+slot, this is forwarded to
+.QW "\fBmy \-append\fR" ),
+and these methods which provide the implementation interface:
+.VE
+.TP
+\fIslot\fR \fBGet\fR
+.VS
+Returns a list that is the current contents of the slot. This method must
+always be called from a stack frame created by a call to \fBoo::define\fR or
+\fBoo::objdefine\fR.
+.VE
+.TP
+\fIslot\fR \fBSet \fIelementList\fR
+.VS
+Sets the contents of the slot to the list \fIelementList\fR and returns the
+empty string. This method must always be called from a stack frame created by
+a call to \fBoo::define\fR or \fBoo::objdefine\fR.
+.PP
+The implementation of these methods is slot-dependent (and responsible for
+accessing the correct part of the class or object definition). Slots also have
+an unknown method handler to tie all these pieces together, and they hide
+their \fBdestroy\fR method so that it is not invoked inadvertently. It is
+\fIrecommended\fR that any user changes to the slot mechanism be restricted to
+defining new operations whose names start with a hyphen.
+.VE
+.SH EXAMPLES

+\fBoo::objdefine\fR commands (they work in the same way), as well as
+illustrating four of the subcommands of them.

+.SH SYNOPSIS
+\fBdict \fIoption arg \fR?\fIarg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+Performs one of several operations on dictionary values or variables
+containing dictionary values (see the \fBDICTIONARY VALUES\fR section
+below for a description), depending on \fIoption\fR.  The legal
+\fIoption\fRs (which may be abbreviated) are:
+.TP
+\fBdict append \fIdictionaryVariable key \fR?\fIstring ...\fR?
+.
+This appends the given string (or strings) to the value that the given
+key maps to in the dictionary value contained in the given variable,
+writing the resulting dictionary value back to that variable.
+Non-existent keys are treated as if they map to an empty string.
+.TP
+\fBdict create \fR?\fIkey value ...\fR?
+.
+Create a new dictionary that contains each of the key/value mappings
+listed as arguments (keys and values alternating, with each key being
+followed by its associated value.)
+.TP
+\fBdict exists \fIdictionaryValue key \fR?\fIkey ...\fR?
+.
+This returns a boolean value indicating whether the given key (or path
+of keys through a set of nested dictionaries) exists in the given
+dictionary value. This returns a true value exactly when \fBdict
+get\fR on that path will succeed.
+.TP
+\fBdict filter \fIdictionaryValue filterType arg \fR?\fIarg ...\fR?
+.
+This takes a dictionary value and returns a new dictionary that
+contains just those key/value pairs that match the specified filter
+type (which may be abbreviated.)  Supported filter types are:
+.RS
+.TP
+\fBdict filter \fIdictionaryValue \fBkey\fR ?\fIglobPattern ...\fR?
+.VS 8.6
+The key rule only matches those key/value pairs whose keys match any
+of the given patterns (in the style of \fBstring match\fR.)
+.VE 8.6
+.TP
+\fBdict filter \fIdictionaryValue \fBscript {\fIkeyVar valueVar\fB} \fIscript\fR
+.
+The script rule tests for matching by assigning the key to the
+\fIkeyVar\fR and the value to the \fIvalueVar\fR, and then evaluating
+the given script which should return a boolean value (with the
+key/value pair only being included in the result of the \fBdict
+filter\fR when a true value is returned.)  Note that the first
+argument after the rule selection word is a two-element list.  If the
+\fIscript\fR returns with a condition of \fBTCL_BREAK\fR, no further
+key/value pairs are considered for inclusion in the resulting
+dictionary, and a condition of \fBTCL_CONTINUE\fR is equivalent to a false
+result. The key/value pairs are tested in the order in which the keys
+were inserted into the dictionary.
+.TP
+\fBdict filter \fIdictionaryValue \fBvalue \fR?\fIglobPattern ...\fR?
+.VS 8.6
+The value rule only matches those key/value pairs whose values match any
+of the given patterns (in the style of \fBstring match\fR.)
+.VE 8.6
+.RE
+.TP
+\fBdict for {\fIkeyVar valueVar\fB} \fIdictionaryValue body\fR
+.
+This command takes three arguments, the first a two-element list of
+variable names (for the key and value respectively of each mapping in
+the dictionary), the second the dictionary value to iterate across,
+and the third a script to be evaluated for each mapping with the key
+and value variables set appropriately (in the manner of \fBforeach\fR.)
+The result of the command is an empty string. If any evaluation of the
+body generates a \fBTCL_BREAK\fR result, no further pairs from the
+dictionary will be iterated over and the \fBdict for\fR command will
+terminate successfully immediately. If any evaluation of the body
+generates a \fBTCL_CONTINUE\fR result, this shall be treated exactly like a
+normal \fBTCL_OK\fR result. The order of iteration is the order in
+which the keys were inserted into the dictionary.
+.TP
+\fBdict get \fIdictionaryValue \fR?\fIkey ...\fR?
+.
+Given a dictionary value (first argument) and a key (second argument),
+this will retrieve the value for that key. Where several keys are
+supplied, the behaviour of the command shall be as if the result of
+\fBdict get $dictVal $key\fR was passed as the first argument to
+\fBdict get\fR with the remaining arguments as second (and possibly
+subsequent) arguments. This facilitates lookups in nested
+dictionaries. For example, the following two commands are equivalent:
+.RS
+.PP
+.CS
+dict get $dict foo bar spong
+dict get [dict get [dict get $dict foo] bar] spong
+.CE
+.PP
+If no keys are provided, \fBdict get\fR will return a list containing pairs of
+elements in a manner similar to \fBarray get\fR. That is, the first
+element of each pair would be the key and the second element would be
+the value for that key.
+.PP
+It is an error to attempt to retrieve a value for a key that is not
+present in the dictionary.
+.RE
+.TP
+\fBdict incr \fIdictionaryVariable key \fR?\fIincrement\fR?
+.
+This adds the given increment value (an integer that defaults to 1 if
+not specified) to the value that the given key maps to in the
+dictionary value contained in the given variable, writing the
+resulting dictionary value back to that variable. Non-existent keys
+are treated as if they map to 0. It is an error to increment a value
+for an existing key if that value is not an integer.
+.TP
+\fBdict info \fIdictionaryValue\fR
+.
+This returns information (intended for display to people) about the
+given dictionary though the format of this data is dependent on the
+implementation of the dictionary. For dictionaries that are
+implemented by hash tables, it is expected that this will return the
+string produced by \fBTcl_HashStats\fR, similar to \fBarray statistics\fR.
+.TP
+\fBdict keys \fIdictionaryValue \fR?\fIglobPattern\fR?
+.
+Return a list of all keys in the given dictionary value. If a pattern
+is supplied, only those keys that match it (according to the rules of
+\fBstring match\fR) will be returned. The returned keys will be in the
+order that they were inserted into the dictionary.
+.TP
+\fBdict lappend \fIdictionaryVariable key \fR?\fIvalue ...\fR?
+.
+This appends the given items to the list value that the given key maps
+to in the dictionary value contained in the given variable, writing
+the resulting dictionary value back to that variable. Non-existent
+keys are treated as if they map to an empty list, and it is legal for
+there to be no items to append to the list. It is an error for the
+value that the key maps to to not be representable as a list.
+.TP
+\fBdict map \fR{\fIkeyVar valueVar\fR} \fIdictionaryValue body\fR
+.
+This command applies a transformation to each element of a dictionary,
+returning a new dictionary. It takes three arguments: the first is a
+two-element list of variable names (for the key and value respectively of each
+mapping in the dictionary), the second the dictionary value to iterate across,
+and the third a script to be evaluated for each mapping with the key and value
+variables set appropriately (in the manner of \fBlmap\fR). In an iteration
+where the evaluated script completes normally (\fBTCL_OK\fR, as opposed to an
+\fBerror\fR, etc.) the result of the script is put into an accumulator
+dictionary using the key that is the current contents of the \fIkeyVar\fR
+variable at that point. The result of the \fBdict map\fR command is the
+accumulator dictionary after all keys have been iterated over.
+.RS
+.PP
+If the evaluation of the body for any particular step generates a \fBbreak\fR,
+no further pairs from the dictionary will be iterated over and the \fBdict
+map\fR command will terminate successfully immediately. If the evaluation of
+the body for a particular step generates a \fBcontinue\fR result, the current
+iteration is aborted and the accumulator dictionary is not modified. The order
+of iteration is the natural order of the dictionary (typically the order in
+which the keys were added to the dictionary; the order is the same as that
+used in \fBdict for\fR).
+.RE
+.TP
+\fBdict merge \fR?\fIdictionaryValue ...\fR?
+.
+Return a dictionary that contains the contents of each of the
+\fIdictionaryValue\fR arguments.  Where two (or more) dictionaries
+contain a mapping for the same key, the resulting dictionary maps that
+key to the value according to the last dictionary on the command line
+containing a mapping for that key.
+.TP
+\fBdict remove \fIdictionaryValue \fR?\fIkey ...\fR?
+.
+Return a new dictionary that is a copy of an old one passed in as
+first argument except without mappings for each of the keys listed.
+It is legal for there to be no keys to remove, and it also legal for
+any of the keys to be removed to not be present in the input
+dictionary in the first place.
+.TP
+\fBdict replace \fIdictionaryValue \fR?\fIkey value ...\fR?
+.
+Return a new dictionary that is a copy of an old one passed in as
+first argument except with some values different or some extra
+key/value pairs added. It is legal for this command to be called with
+no key/value pairs, but illegal for this command to be called with a
+key but no value.
+.TP
+\fBdict set \fIdictionaryVariable key \fR?\fIkey ...\fR? \fIvalue\fR
+.
+This operation takes the name of a variable containing a dictionary
+value and places an updated dictionary value in that variable
+containing a mapping from the given key to the given value. When
+multiple keys are present, this operation creates or updates a chain
+of nested dictionaries.
+.TP
+\fBdict size \fIdictionaryValue\fR
+.
+Return the number of key/value mappings in the given dictionary value.
+.TP
+\fBdict unset \fIdictionaryVariable key \fR?\fIkey ...\fR?
+.
+This operation (the companion to \fBdict set\fR) takes the name of a
+variable containing a dictionary value and places an updated
+dictionary value in that variable that does not contain a mapping for
+the given key. Where multiple keys are present, this describes a path
+through nested dictionaries to the mapping to remove. At least one key
+must be specified, but the last key on the key-path need not exist.
+All other components on the path must exist.
+.TP
+\fBdict update \fIdictionaryVariable key varName \fR?\fIkey varName ...\fR? \fIbody\fR
+.
+Execute the Tcl script in \fIbody\fR with the value for each \fIkey\fR
+(as found by reading the dictionary value in \fIdictionaryVariable\fR)
+mapped to the variable \fIvarName\fR. There may be multiple
+\fIkey\fR/\fIvarName\fR pairs. If a \fIkey\fR does not have a mapping,
+that corresponds to an unset \fIvarName\fR. When \fIbody\fR
+terminates, any changes made to the \fIvarName\fRs is reflected back
+to the dictionary within \fIdictionaryVariable\fR (unless
+\fIdictionaryVariable\fR itself becomes unreadable, when all updates
+are silently discarded), even if the result of \fIbody\fR is an error
+or some other kind of exceptional exit. The result of \fBdict
+update\fR is (unless some kind of error occurs) the result of the
+evaluation of \fIbody\fR.
+.RS
+.PP
+Each \fIvarName\fR is mapped in the scope enclosing the \fBdict update\fR;
+it is recommended that this command only be used in a local scope
+(\fBproc\fRedure, lambda term for \fBapply\fR, or method). Because of
+this, the variables set by \fBdict update\fR will continue to
+exist after the command finishes (unless explicitly \fBunset\fR).
+Note that the mapping of values to variables
+does not use traces; changes to the \fIdictionaryVariable\fR's
+contents only happen when \fIbody\fR terminates.
+.RE
+.TP
+\fBdict values \fIdictionaryValue \fR?\fIglobPattern\fR?
+.
+Return a list of all values in the given dictionary value. If a
+pattern is supplied, only those values that match it (according to the
+rules of \fBstring match\fR) will be returned. The returned values
+will be in the order of that the keys associated with those values
+were inserted into the dictionary.
+.TP
+\fBdict with \fIdictionaryVariable \fR?\fIkey ...\fR? \fIbody\fR
+.
+Execute the Tcl script in \fIbody\fR with the value for each key in
+\fIdictionaryVariable\fR mapped (in a manner similarly to \fBdict
+update\fR) to a variable with the same name. Where one or more
+\fIkey\fRs are available, these indicate a chain of nested
+dictionaries, with the innermost dictionary being the one opened out
+for the execution of \fIbody\fR. As with \fBdict update\fR, making
+\fIdictionaryVariable\fR unreadable will make the updates to the
+dictionary be discarded, and this also happens if the contents of
+\fIdictionaryVariable\fR are adjusted so that the chain of
+dictionaries no longer exists. The result of \fBdict with\fR is
+(unless some kind of error occurs) the result of the evaluation of
+\fIbody\fR.
+.RS
+.PP
+The variables are mapped in the scope enclosing the \fBdict with\fR;
+it is recommended that this command only be used in a local scope
+(\fBproc\fRedure, lambda term for \fBapply\fR, or method). Because of
+this, the variables set by \fBdict with\fR will continue to
+exist after the command finishes (unless explicitly \fBunset\fR).
+Note that the mapping of values to variables does not use
+traces; changes to the \fIdictionaryVariable\fR's contents only happen
+when \fIbody\fR terminates.
+.PP
+If the \fIdictionaryVariable\fR contains a value that is not a dictionary at
+the point when the \fIbody\fR terminates (which can easily happen if the name
+is the same as any of the keys in dictionary) then an error occurs at that
+point. This command is thus not recommended for use when the keys in the
+dictionary are expected to clash with the \fIdictionaryVariable\fR name
+itself. Where the contained key does map to a dictionary, the net effect is to
+combine that inner dictionary into the outer dictionary; see the
+\fBEXAMPLES\fR below for an illustration of this.
+.RE
+.SH "DICTIONARY VALUES"
+.PP
+Dictionaries are values that contain an efficient, order-preserving
+mapping from arbitrary keys to arbitrary values.
+Each key in the dictionary maps to a single value.
+They have a textual format that is exactly that of any list with an
+even number of elements, with each mapping in the dictionary being
+represented as two items in the list. When a command takes a
+dictionary and produces a new dictionary based on it (either returning
+it or writing it back into the variable that the starting dictionary
+was read from) the new dictionary will have the same order of keys,
+modulo any deleted keys and with new keys added on to the end.
+When a string is interpreted as a dictionary and it would otherwise
+have duplicate keys, only the last value for a particular key is used;
+the others are ignored, meaning that,
+.QW "apple banana"
+and
+.QW "apple carrot apple banana"
+are equivalent dictionaries (with different string representations).
+.PP
+Operations that derive a new dictionary from an old one (e.g., updates
+like \fBdict set\fR and \fBdict unset\fR) preserve the order of keys
+in the dictionary. The exceptions to this are for any new keys they
+add, which are appended to the sequence, and any keys that are
+removed, which are excised from the order.

+.SH NAME
+encoding \- Manipulate encodings
+.SH SYNOPSIS
+\fBencoding \fIoption\fR ?\fIarg arg ...\fR?
+.BE
+.SH INTRODUCTION
+.PP
+Strings in Tcl are encoded using 16-bit Unicode characters.  Different
+operating system interfaces or applications may generate strings in
+other encodings such as Shift-JIS.  The \fBencoding\fR command helps
+to bridge the gap between Unicode and these other formats.
+.SH DESCRIPTION
+.PP
+Performs one of several encoding related operations, depending on
+\fIoption\fR.  The legal \fIoption\fRs are:
+.TP
+\fBencoding convertfrom\fR ?\fIencoding\fR? \fIdata\fR
+.
+Convert \fIdata\fR to Unicode from the specified \fIencoding\fR.  The
+characters in \fIdata\fR are treated as binary data where the lower
+8-bits of each character is taken as a single byte.  The resulting
+sequence of bytes is treated as a string in the specified
+\fIencoding\fR.  If \fIencoding\fR is not specified, the current
+system encoding is used.
+.TP
+\fBencoding convertto\fR ?\fIencoding\fR? \fIstring\fR
+.
+Convert \fIstring\fR from Unicode to the specified \fIencoding\fR.
+The result is a sequence of bytes that represents the converted
+string.  Each byte is stored in the lower 8-bits of a Unicode
+character.  If \fIencoding\fR is not specified, the current
+system encoding is used.
+.TP
+\fBencoding dirs\fR ?\fIdirectoryList\fR?
+.
+Tcl can load encoding data files from the file system that describe
+additional encodings for it to work with. This command sets the search
+path for \fB*.enc\fR encoding data files to the list of directories
+\fIdirectoryList\fR. If \fIdirectoryList\fR is omitted then the
+command returns the current list of directories that make up the
+search path. It is an error for \fIdirectoryList\fR to not be a valid
+list. If, when a search for an encoding data file is happening, an
+element in \fIdirectoryList\fR does not refer to a readable,
+searchable directory, that element is ignored.
+.TP
+\fBencoding names\fR
+.
+Returns a list containing the names of all of the encodings that are
+currently available. 
+.TP
+\fBencoding system\fR ?\fIencoding\fR?
+.
+Set the system encoding to \fIencoding\fR. If \fIencoding\fR is
+omitted then the command returns the current system encoding.  The
+system encoding is used whenever Tcl passes strings to system calls.
+.SH EXAMPLE
+.PP
+It is common practice to write script files using a text editor that
+produces output in the euc-jp encoding, which represents the ASCII
+characters as singe bytes and Japanese characters as two bytes.  This
+makes it easy to embed literal strings that correspond to non-ASCII
+characters by simply typing the strings in place in the script.
+However, because the \fBsource\fR command always reads files using the
+current system encoding, Tcl will only source such files correctly
+when the encoding used to write the file is the same.  This tends not
+to be true in an internationalized setting.  For example, if such a
+file was sourced in North America (where the ISO8859-1 is normally
+used), each byte in the file would be treated as a separate character
+that maps to the 00 page in Unicode.  The resulting Tcl strings will
+not contain the expected Japanese characters.  Instead, they will
+contain a sequence of Latin-1 characters that correspond to the bytes
+of the original string.  The \fBencoding\fR command can be used to
+convert this string to the expected Japanese Unicode characters.  For
+example,
+.PP
+.CS
+set s [\fBencoding convertfrom\fR euc-jp "\exA4\exCF"]
+.CE
+.PP
+would return the Unicode string
+.QW "\eu306F" ,
+which is the Hiragana letter HA.

+error \- Generate an error
+.SH SYNOPSIS
+\fBerror \fImessage\fR ?\fIinfo\fR? ?\fIcode\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+Returns a \fBTCL_ERROR\fR code, which causes command interpretation to be
+unwound.  \fIMessage\fR is a string that is returned to the application
+to indicate what went wrong.
+.PP
+The \fB\-errorinfo\fR return option of an interpreter is used
+to accumulate a stack trace of what was in progress when an
+error occurred; as nested commands unwind,
+the Tcl interpreter adds information to the \fB\-errorinfo\fR
+return option.  If the \fIinfo\fR argument is present, it is
+used to initialize the \fB\-errorinfo\fR return options and
+the first increment of unwind information
+will not be added by the Tcl interpreter.  
+In other
+words, the command containing the \fBerror\fR command will not appear
+in the stack trace; in its place will be \fIinfo\fR.
+Historically, this feature had been most useful in conjunction
+with the \fBcatch\fR command:
+if a caught error cannot be handled successfully, \fIinfo\fR can be used
+to return a stack trace reflecting the original point of occurrence
+of the error:
+.PP
+.CS
+catch {...} errMsg
+set savedInfo $::errorInfo
+\&...
+\fBerror\fR $errMsg $savedInfo
+.CE
+.PP
+When working with Tcl 8.5 or later, the following code
+should be used instead:
+.PP
+.CS
+catch {...} errMsg options
+\&...
+return -options $options $errMsg
+.CE
+.PP
+If the \fIcode\fR argument is present, then its value is stored
+in the \fB\-errorcode\fR return option.  The \fB\-errorcode\fR
+return option is intended to hold a machine-readable description
+of the error in cases where such information is available; see
+the \fBreturn\fR manual page for information on the proper format
+for this option's value.

+.SH NAME
+eval \- Evaluate a Tcl script
+.SH SYNOPSIS
+\fBeval \fIarg \fR?\fIarg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+\fBEval\fR takes one or more arguments, which together comprise a Tcl
+script containing one or more commands.
+\fBEval\fR concatenates all its arguments in the same
+fashion as the \fBconcat\fR command, passes the concatenated string to the
+Tcl interpreter recursively, and returns the result of that
+evaluation (or any error generated by it).
+Note that the \fBlist\fR command quotes sequences of words in such a
+way that they are not further expanded by the \fBeval\fR command.
+.SH EXAMPLES
+.PP
+Often, it is useful to store a fragment of a script in a variable and
+execute it later on with extra values appended. This technique is used
+in a number of places throughout the Tcl core (e.g. in \fBfcopy\fR,
+\fBlsort\fR and \fBtrace\fR command callbacks). This example shows how
+to do this using core Tcl commands:
+.PP
+.CS
+set script {
+    puts "logging now"
+    lappend $myCurrentLogVar
+}
+set myCurrentLogVar log1
+# Set up a switch of logging variable part way through!
+after 20000 set myCurrentLogVar log2
+
+for {set i 0} {$i<10} {incr i} {
+    # Introduce a random delay
+    after [expr {int(5000 * rand())}]
+    update    ;# Check for the asynch log switch
+    \fBeval\fR $script $i [clock clicks]
+}
+.CE
+.PP
+Note that in the most common case (where the script fragment is
+actually just a list of words forming a command prefix), it is better
+to use \fB{*}$script\fR when doing this sort of invocation
+pattern.  It is less general than the \fBeval\fR command, and hence
+easier to make robust in practice.
+The following procedure acts in a way that is analogous to the
+\fBlappend\fR command, except it inserts the argument values at the
+start of the list in the variable:
+.PP
+.CS
+proc lprepend {varName args} {
+    upvar 1 $varName var
+    # Ensure that the variable exists and contains a list
+    lappend var
+    # Now we insert all the arguments in one go
+    set var [\fBeval\fR [list linsert $var 0] $args]
+}
+.CE
+.PP
+However, the last line would now normally be written without
+\fBeval\fR, like this:
+.PP
+.CS
+set var [linsert $var 0 {*}$args]

+exec \- Invoke subprocesses
+.SH SYNOPSIS
+\fBexec \fR?\fIswitches\fR? \fIarg \fR?\fIarg ...\fR? ?\fB&\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command treats its arguments as the specification
+of one or more subprocesses to execute.
+The arguments take the form of a standard shell pipeline
+where each \fIarg\fR becomes one word of a command, and
+each distinct command becomes a subprocess.
+.PP
+If the initial arguments to \fBexec\fR start with \fB\-\fR then
+they are treated as command-line switches and are not part
+of the pipeline specification.  The following switches are
+currently supported:
+.TP 13
+\fB\-ignorestderr\fR
+.
+Stops the \fBexec\fR command from treating the output of messages to the
+pipeline's standard error channel as an error case.
+.TP 13
+\fB\-keepnewline\fR
+.
+Retains a trailing newline in the pipeline's output.
+Normally a trailing newline will be deleted.
+.TP 13
+\fB\-\|\-\fR
+.
+Marks the end of switches.  The argument following this one will
+be treated as the first \fIarg\fR even if it starts with a \fB\-\fR.
+.PP
+If an \fIarg\fR (or pair of \fIarg\fRs) has one of the forms
+described below then it is used by \fBexec\fR to control the
+flow of input and output among the subprocess(es).
+Such arguments will not be passed to the subprocess(es).  In forms
+such as
+.QW "\fB<\fR \fIfileName\fR" ,
+\fIfileName\fR may either be in a separate argument from
+.QW \fB<\fR
+or in the same argument with no intervening space (i.e.
+.QW \fB<\fIfileName\fR ).
+.TP 15
+\fB|\fR
+.
+Separates distinct commands in the pipeline.  The standard output
+of the preceding command will be piped into the standard input
+of the next command.
+.TP 15
+\fB|&\fR
+.
+Separates distinct commands in the pipeline.  Both standard output
+and standard error of the preceding command will be piped into
+the standard input of the next command.
+This form of redirection overrides forms such as 2> and >&.
+.TP 15
+\fB<\0\fIfileName\fR
+.
+The file named by \fIfileName\fR is opened and used as the standard
+input for the first command in the pipeline.
+.TP 15
+\fB<@\0\fIfileId\fR
+.
+\fIFileId\fR must be the identifier for an open file, such as the return
+value from a previous call to \fBopen\fR.
+It is used as the standard input for the first command in the pipeline.
+\fIFileId\fR must have been opened for reading.
+.TP 15
+\fB<<\0\fIvalue\fR
+.
+\fIValue\fR is passed to the first command as its standard input.
+.TP 15
+\fB>\0\fIfileName\fR
+.
+Standard output from the last command is redirected to the file named
+\fIfileName\fR, overwriting its previous contents.
+.TP 15
+\fB2>\0\fIfileName\fR
+.
+Standard error from all commands in the pipeline is redirected to the
+file named \fIfileName\fR, overwriting its previous contents.
+.TP 15
+\fB>&\0\fIfileName\fR
+.
+Both standard output from the last command and standard error from all
+commands are redirected to the file named \fIfileName\fR, overwriting
+its previous contents.
+.TP 15
+\fB>>\0\fIfileName\fR
+.
+Standard output from the last command is
+redirected to the file named \fIfileName\fR, appending to it rather
+than overwriting it.
+.TP 15
+\fB2>>\0\fIfileName\fR
+.
+Standard error from all commands in the pipeline is
+redirected to the file named \fIfileName\fR, appending to it rather
+than overwriting it.
+.TP 15
+\fB>>&\0\fIfileName\fR
+.
+Both standard output from the last command and standard error from
+all commands are redirected to the file named \fIfileName\fR,
+appending to it rather than overwriting it.
+.TP 15
+\fB>@\0\fIfileId\fR
+.
+\fIFileId\fR must be the identifier for an open file, such as the return
+value from a previous call to \fBopen\fR.
+Standard output from the last command is redirected to \fIfileId\fR's
+file, which must have been opened for writing.
+.TP 15
+\fB2>@\0\fIfileId\fR
+.
+\fIFileId\fR must be the identifier for an open file, such as the return
+value from a previous call to \fBopen\fR.
+Standard error from all commands in the pipeline is
+redirected to \fIfileId\fR's file.
+The file must have been opened for writing.
+.TP 15
+\fB2>@1\0\fR
+.
+Standard error from all commands in the pipeline is redirected to the
+command result.  This operator is only valid at the end of the command
+pipeline.
+.TP 15
+\fB>&@\0\fIfileId\fR
+.
+\fIFileId\fR must be the identifier for an open file, such as the return
+value from a previous call to \fBopen\fR.
+Both standard output from the last command and standard error from
+all commands are redirected to \fIfileId\fR's file.
+The file must have been opened for writing.
+.PP
+If standard output has not been redirected then the \fBexec\fR
+command returns the standard output from the last command
+in the pipeline, unless
+.QW 2>@1
+was specified, in which case standard error is included as well.
+If any of the commands in the pipeline exit abnormally or
+are killed or suspended, then \fBexec\fR will return an error
+and the error message will include the pipeline's output followed by
+error messages describing the abnormal terminations; the
+\fB\-errorcode\fR return option will contain additional information
+about the last abnormal termination encountered.
+If any of the commands writes to its standard error file and that
+standard error is not redirected
+and \fB\-ignorestderr\fR is not specified,
+then \fBexec\fR will return an error;  the error message
+will include the pipeline's standard output, followed by messages
+about abnormal terminations (if any), followed by the standard error
+output.
+.PP
+If the last character of the result or error message
+is a newline then that character is normally deleted
+from the result or error message.
+This is consistent with other Tcl return values, which do not
+normally end with newlines.
+However, if \fB\-keepnewline\fR is specified then the trailing
+newline is retained.
+.PP
+If standard input is not redirected with
+.QW < ,
+.QW <<
+or
+.QW <@
+then the standard input for the first command in the
+pipeline is taken from the application's current standard input.
+.PP
+If the last \fIarg\fR is
+.QW &
+then the pipeline will be executed in background.
+In this case the \fBexec\fR command will return a list whose
+elements are the process identifiers for all of the subprocesses
+in the pipeline.
+The standard output from the last command in the pipeline will
+go to the application's standard output if it has not been
+redirected, and error output from all of
+the commands in the pipeline will go to the application's
+standard error file unless redirected.
+.PP
+The first word in each command is taken as the command name;
+tilde-substitution is performed on it, and if the result contains
+no slashes then the directories
+in the PATH environment variable are searched for
+an executable by the given name.
+If the name contains a slash then it must refer to an executable
+reachable from the current directory.
+No
+.QW glob
+expansion or other shell-like substitutions
+are performed on the arguments to commands.
+.SH "PORTABILITY ISSUES"
+.TP
+\fBWindows\fR (all versions)
+.
+Reading from or writing to a socket, using the
+.QW \fB@\0\fIfileId\fR
+notation, does not work.  When reading from a socket, a 16-bit DOS
+application will hang and a 32-bit application will return immediately with
+end-of-file.  When either type of application writes to a socket, the
+information is instead sent to the console, if one is present, or is
+discarded.
+.RS
+.PP
+The Tk console text widget does not provide real standard IO capabilities.
+Under Tk, when redirecting from standard input, all applications will see an
+immediate end-of-file; information redirected to standard output or standard
+error will be discarded.  
+.PP
+Either forward or backward slashes are accepted as path separators for
+arguments to Tcl commands.  When executing an application, the path name
+specified for the application may also contain forward or backward slashes
+as path separators.  Bear in mind, however, that most Windows applications
+accept arguments with forward slashes only as option delimiters and
+backslashes only in paths.  Any arguments to an application that specify a
+path name with forward slashes will not automatically be converted to use
+the backslash character.  If an argument contains forward slashes as the
+path separator, it may or may not be recognized as a path name, depending on
+the program.  
+.PP
+Additionally, when calling a 16-bit DOS or Windows 3.X application, all path
+names must use the short, cryptic, path format (e.g., using
+.QW applba~1.def
+instead of
+.QW applbakery.default ),
+which can be obtained with the
+.QW "\fBfile attributes\fI fileName \fB\-shortname\fR"
+command.
+.PP
+Two or more forward or backward slashes in a row in a path refer to a
+network path.  For example, a simple concatenation of the root directory
+\fBc:/\fR with a subdirectory \fB/windows/system\fR will yield
+\fBc://windows/system\fR (two slashes together), which refers to the mount
+point called \fBsystem\fR on the machine called \fBwindows\fR (and the
+\fBc:/\fR is ignored), and is not equivalent to \fBc:/windows/system\fR,
+which describes a directory on the current computer.  The \fBfile join\fR
+command should be used to concatenate path components.
+.PP
+Note that there are two general types of Win32 console applications:
+.RS
+.IP [1]
+CLI \(em CommandLine Interface, simple stdio exchange. \fBnetstat.exe\fR for
+example.
+.IP [2]
+TUI \(em Textmode User Interface, any application that accesses the console
+API for doing such things as cursor movement, setting text color, detecting
+key presses and mouse movement, etc.  An example would be \fBtelnet.exe\fR
+from Windows 2000.  These types of applications are not common in a windows
+environment, but do exist.
+.RE
+.PP
+\fBexec\fR will not work well with TUI applications when a console is not
+present, as is done when launching applications under wish.  It is desirable
+to have console applications hidden and detached.  This is a designed-in
+limitation as \fBexec\fR wants to communicate over pipes.  The Expect
+extension addresses this issue when communicating with a TUI application.
+.RE
+.TP
+\fBWindows NT\fR
+.
+When attempting to execute an application, \fBexec\fR first searches for
+the name as it was specified.  Then, in order, \fB.com\fR, \fB.exe\fR, and
+\fB.bat\fR are appended to the end of the specified name and it searches
+for the longer name.  If a directory name was not specified as part of the
+application name, the following directories are automatically searched in
+order when attempting to locate the application:
+.RS
+.IP \(bu 3
+The directory from which the Tcl executable was loaded.

+.PP
+In order to execute shell built-in commands like \fBdir\fR and \fBcopy\fR,

+Once a 16-bit DOS application has read standard input from a console and 
+then quit, all subsequently run 16-bit DOS applications will see the 
+standard input as already closed.  32-bit applications do not have this
+problem and will run correctly, even after a 16-bit DOS application thinks 
+that standard input is closed.  There is no known workaround for this bug
+at this time.
+.PP
+Redirection between the \fBNUL:\fR device and a 16-bit application does not
+always work.  When redirecting from \fBNUL:\fR, some applications may hang,
+others will get an infinite stream of
+.QW 0x01
+bytes, and some will actually
+correctly get an immediate end-of-file; the behavior seems to depend upon 
+something compiled into the application itself.  When redirecting greater than
+4K or so to \fBNUL:\fR, some applications will hang.  The above problems do not
+happen with 32-bit applications.  
+.PP
+All DOS 16-bit applications are run synchronously.  All standard input from
+a pipe to a 16-bit DOS application is collected into a temporary file; the
+other end of the pipe must be closed before the 16-bit DOS application
+begins executing.  All standard output or error from a 16-bit DOS
+application to a pipe is collected into temporary files; the application
+must terminate before the temporary files are redirected to the next stage
+of the pipeline.  This is due to a workaround for a Windows 95 bug in the
+implementation of pipes, and is how the standard Windows 95 DOS shell
+handles pipes itself.
+.PP
+Certain applications, such as \fBcommand.com\fR, should not be executed
+interactively.  Applications which directly access the console window,
+rather than reading from their standard input and writing to their standard
+output may fail, hang Tcl, or even hang the system if their own private

+.SH NAME
+expr \- Evaluate an expression
+.SH SYNOPSIS
+\fBexpr \fIarg \fR?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+Concatenates \fIarg\fRs (adding separator spaces between them),
+evaluates the result as a Tcl expression, and returns the value.
+The operators permitted in Tcl expressions include a subset of
+the operators permitted in C expressions.  For those operators
+common to both Tcl and C, Tcl applies the same meaning and precedence
+as the corresponding C operators.
+Expressions almost always yield numeric results
+(integer or floating-point values).
+For example, the expression
+.PP
+.CS
+\fBexpr\fR 8.2 + 6
+.CE
+.PP
+evaluates to 14.2.
+Tcl expressions differ from C expressions in the way that
+operands are specified.  Also, Tcl expressions support
+non-numeric operands and string comparisons, as well as some
+additional operators not found in C.
+.SS OPERANDS
+.PP
+A Tcl expression consists of a combination of operands, operators,
+parentheses and commas.
+White space may be used between the operands and operators and
+parentheses (or commas); it is ignored by the expression's instructions.
+Where possible, operands are interpreted as integer values.
+Integer values may be specified in decimal (the normal case), in binary
+(if the first two characters of the operand are \fB0b\fR), in octal
+(if the first two characters of the operand are \fB0o\fR), or in hexadecimal
+(if the first two characters of the operand are \fB0x\fR).  For
+compatibility with older Tcl releases, an octal integer value is also
+indicated simply when the first character of the operand is \fB0\fR,
+whether or not the second character is also \fBo\fR.
+If an operand does not have one of the integer formats given
+above, then it is treated as a floating-point number if that is
+possible.  Floating-point numbers may be specified in any of several
+common formats making use of the decimal digits, the decimal point \fB.\fR,
+the characters \fBe\fR or \fBE\fR indicating scientific notation, and
+the sign characters \fB+\fR or \fB\-\fR.  For example, all of the
+following are valid floating-point numbers:  2.1, 3., 6e4, 7.91e+16.
+Also recognized as floating point values are the strings \fBInf\fR
+and \fBNaN\fR making use of any case for each character.
+If no numeric interpretation is possible (note that all literal
+operands that are not numeric or boolean must be quoted with either
+braces or with double quotes), then an operand is left as a string
+(and only a limited set of operators may be applied to it).
+.PP
+Operands may be specified in any of the following ways:
+.IP [1]
+As a numeric value, either integer or floating-point.
+.IP [2]
+As a boolean value, using any form understood by \fBstring is\fR
+\fBboolean\fR.
+.IP [3]
+As a Tcl variable, using standard \fB$\fR notation.
+The variable's value will be used as the operand.
+.IP [4]
+As a string enclosed in double-quotes.
+The expression parser will perform backslash, variable, and
+command substitutions on the information between the quotes,
+and use the resulting value as the operand
+.IP [5]
+As a string enclosed in braces.
+The characters between the open brace and matching close brace
+will be used as the operand without any substitutions.
+.IP [6]
+As a Tcl command enclosed in brackets.
+The command will be executed and its result will be used as
+the operand.
+.IP [7]
+As a mathematical function whose arguments have any of the above
+forms for operands, such as \fBsin($x)\fR.  See \fBMATH FUNCTIONS\fR below for
+a discussion of how mathematical functions are handled.
+.PP
+Where the above substitutions occur (e.g. inside quoted strings), they
+are performed by the expression's instructions.
+However, the command parser may already have performed one round of
+substitution before the expression processor was called.
+As discussed below, it is usually best to enclose expressions
+in braces to prevent the command parser from performing substitutions
+on the contents.
+.PP
+For some examples of simple expressions, suppose the variable
+\fBa\fR has the value 3 and
+the variable \fBb\fR has the value 6.
+Then the command on the left side of each of the lines below
+will produce the value on the right side of the line:
+.PP
+.CS
+.ta 6c
+\fBexpr\fR 3.1 + $a	\fI6.1\fR
+\fBexpr\fR 2 + "$a.$b"	\fI5.6\fR
+\fBexpr\fR 4*[llength "6 2"]	\fI8\fR
+\fBexpr\fR {{word one} < "word $a"}	\fI0\fR
+.CE
+.SS OPERATORS
+.PP
+The valid operators (most of which are also available as commands in
+the \fBtcl::mathop\fR namespace; see the \fBmathop\fR(n) manual page
+for details) are listed below, grouped in decreasing order of precedence:
+.TP 20
+\fB\-\0\0+\0\0~\0\0!\fR
+.
+Unary minus, unary plus, bit-wise NOT, logical NOT.  None of these operators
+may be applied to string operands, and bit-wise NOT may be
+applied only to integers.
+.TP 20
+\fB**\fR
+.
+Exponentiation.  Valid for any numeric operands.
+.TP 20
+\fB*\0\0/\0\0%\fR
+.
+Multiply, divide, remainder.  None of these operators may be
+applied to string operands, and remainder may be applied only
+to integers.
+The remainder will always have the same sign as the divisor and
+an absolute value smaller than the absolute value of the divisor.
+.RS
+.PP
+When applied to integers, the division and remainder operators can be
+considered to partition the number line into a sequence of equal-sized
+adjacent non-overlapping pieces where each piece is the size of the divisor;
+the division result identifies which piece the divisor lay within, and the
+remainder result identifies where within that piece the divisor lay. A
+consequence of this is that the result of
+.QW "-57 \fB/\fR 10"
+is always -6, and the result of
+.QW "-57 \fB%\fR 10"
+is always 3.
+.RE
+.TP 20
+\fB+\0\0\-\fR
+.
+Add and subtract.  Valid for any numeric operands.
+.TP 20
+\fB<<\0\0>>\fR
+.
+Left and right shift.  Valid for integer operands only.
+A right shift always propagates the sign bit.
+.TP 20
+\fB<\0\0>\0\0<=\0\0>=\fR
+.
+Boolean less, greater, less than or equal, and greater than or equal.
+Each operator produces 1 if the condition is true, 0 otherwise.
+These operators may be applied to strings as well as numeric operands,
+in which case string comparison is used.
+.TP 20
+\fB==\0\0!=\fR
+.
+Boolean equal and not equal.  Each operator produces a zero/one result.
+Valid for all operand types.
+.TP 20
+\fBeq\0\0ne\fR
+.
+Boolean string equal and string not equal.  Each operator produces a
+zero/one result.  The operand types are interpreted only as strings.
+.TP 20
+\fBin\0\0ni\fR
+.
+List containment and negated list containment.  Each operator produces
+a zero/one result and treats its first argument as a string and its
+second argument as a Tcl list.  The \fBin\fR operator indicates
+whether the first argument is a member of the second argument list;
+the \fBni\fR operator inverts the sense of the result.
+.TP 20
+\fB&\fR
+.
+Bit-wise AND.  Valid for integer operands only.
+.TP 20
+\fB^\fR
+.
+Bit-wise exclusive OR.  Valid for integer operands only.
+.TP 20
+\fB|\fR
+.
+Bit-wise OR.  Valid for integer operands only.
+.TP 20
+\fB&&\fR
+.
+Logical AND.  Produces a 1 result if both operands are non-zero,
+0 otherwise.
+Valid for boolean and numeric (integers or floating-point) operands only.
+.TP 20
+\fB||\fR
+.
+Logical OR.  Produces a 0 result if both operands are zero, 1 otherwise.
+Valid for boolean and numeric (integers or floating-point) operands only.
+.TP 20
+\fIx\fB?\fIy\fB:\fIz\fR
+.
+If-then-else, as in C.  If \fIx\fR
+evaluates to non-zero, then the result is the value of \fIy\fR.
+Otherwise the result is the value of \fIz\fR.
+The \fIx\fR operand must have a boolean or numeric value.
+.PP
+See the C manual for more details on the results
+produced by each operator.
+The exponentiation operator promotes types like the multiply and
+divide operators, and produces a result that is the same as the output
+of the \fBpow\fR function (after any type conversions.)
+All of the binary operators but exponentiation group left-to-right
+within the same precedence level; exponentiation groups right-to-left.  For example, the command
+.PP
+.CS
+\fBexpr\fR {4*2 < 7}
+.CE
+.PP
+returns 0, while
+.PP
+.CS
+\fBexpr\fR {2**3**2}
+.CE
+.PP
+returns 512.
+.PP
+The \fB&&\fR, \fB||\fR, and \fB?:\fR operators have
+.QW "lazy evaluation" ,
+just as in C, which means that operands are not evaluated if they are
+not needed to determine the outcome.  For example, in the command
+.PP
+.CS
+\fBexpr\fR {$v ? [a] : [b]}
+.CE
+.PP
+only one of
+.QW \fB[a]\fR
+or
+.QW \fB[b]\fR
+will actually be evaluated,
+depending on the value of \fB$v\fR.  Note, however, that this is
+only true if the entire expression is enclosed in braces;  otherwise
+the Tcl parser will evaluate both
+.QW \fB[a]\fR
+and
+.QW \fB[b]\fR
+before invoking the \fBexpr\fR command.
+.SS "MATH FUNCTIONS"
+.PP
+When the expression parser encounters a mathematical function
+such as \fBsin($x)\fR, it replaces it with a call to an ordinary
+Tcl function in the \fBtcl::mathfunc\fR namespace.  The processing
+of an expression such as:
+.PP
+.CS
+\fBexpr\fR {sin($x+$y)}
+.CE
+.PP
+is the same in every way as the processing of:
+.PP
+.CS
+\fBexpr\fR {[tcl::mathfunc::sin [\fBexpr\fR {$x+$y}]]}
+.CE
+.PP
+which in turn is the same as the processing of:
+.PP
+.CS
+tcl::mathfunc::sin [\fBexpr\fR {$x+$y}]
+.CE
+.PP
+The executor will search for \fBtcl::mathfunc::sin\fR using the usual
+rules for resolving functions in namespaces. Either
+\fB::tcl::mathfunc::sin\fR or \fB[namespace
+current]::tcl::mathfunc::sin\fR will satisfy the request, and others
+may as well (depending on the current \fBnamespace path\fR setting).
+.PP
+Some mathematical functions have several arguments, separated by commas like in C. Thus:
+.PP
+.CS
+\fBexpr\fR {hypot($x,$y)}
+.CE
+.PP
+ends up as
+.PP
+.CS
+tcl::mathfunc::hypot $x $y
+.CE
+.PP
+See the \fBmathfunc\fR(n) manual page for the math functions that are
+available by default.
+.SS "TYPES, OVERFLOW, AND PRECISION"
+.PP
+All internal computations involving integers are done calling on the
+LibTomMath multiple precision integer library as required so that all
+integer calculations are performed exactly.  Note that in Tcl releases
+prior to 8.5, integer calculations were performed with one of the C types
+\fIlong int\fR or \fITcl_WideInt\fR, causing implicit range truncation
+in those calculations where values overflowed the range of those types.
+Any code that relied on these implicit truncations will need to explicitly
+add \fBint()\fR or \fBwide()\fR function calls to expressions at the points
+where such truncation is required to take place.
+.PP
+All internal computations involving floating-point are
+done with the C type \fIdouble\fR.
+When converting a string to floating-point, exponent overflow is
+detected and results in the \fIdouble\fR value of \fBInf\fR or
+\fB\-Inf\fR as appropriate.  Floating-point overflow and underflow
+are detected to the degree supported by the hardware, which is generally
+pretty reliable.
+.PP
+Conversion among internal representations for integer, floating-point,
+and string operands is done automatically as needed.
+For arithmetic computations, integers are used until some
+floating-point number is introduced, after which floating-point is used.
+For example,
+.PP
+.CS
+\fBexpr\fR {5 / 4}
+.CE
+.PP
+returns 1, while
+.PP
+.CS
+\fBexpr\fR {5 / 4.0}
+\fBexpr\fR {5 / ( [string length "abcd"] + 0.0 )}
+.CE
+.PP
+both return 1.25.
+Floating-point values are always returned with a
+.QW \fB.\fR
+or an
+.QW \fBe\fR
+so that they will not look like integer values.  For example,
+.PP
+.CS
+\fBexpr\fR {20.0/5.0}
+.CE
+.PP
+returns \fB4.0\fR, not \fB4\fR.
+.SS "STRING OPERATIONS"
+.PP
+String values may be used as operands of the comparison operators,
+although the expression evaluator tries to do comparisons as integer
+or floating-point when it can,
+i.e., when all arguments to the operator allow numeric interpretations,
+except in the case of the \fBeq\fR and \fBne\fR operators.
+If one of the operands of a comparison is a string and the other
+has a numeric value, a canonical string representation of the numeric
+operand value is generated to compare with the string operand.
+Canonical string representation for integer values is a decimal string
+format.  Canonical string representation for floating-point values
+is that produced by the \fB%g\fR format specifier of Tcl's
+\fBformat\fR command.  For example, the commands
+.PP
+.CS
+\fBexpr\fR {"0x03" > "2"}
+\fBexpr\fR {"0y" > "0x12"}
+.CE
+.PP
+both return 1.  The first comparison is done using integer
+comparison, and the second is done using string comparison.
+Because of Tcl's tendency to treat values as numbers whenever
+possible, it is not generally a good idea to use operators like \fB==\fR
+when you really want string comparison and the values of the
+operands could be arbitrary;  it is better in these cases to use
+the \fBeq\fR or \fBne\fR operators, or the \fBstring\fR command instead.
+.SH "PERFORMANCE CONSIDERATIONS"
+.PP
+Enclose expressions in braces for the best speed and the smallest
+storage requirements.
+This allows the Tcl bytecode compiler to generate the best code.
+.PP
+As mentioned above, expressions are substituted twice:
+once by the Tcl parser and once by the \fBexpr\fR command.
+For example, the commands
+.PP
+.CS
+set a 3
+set b {$a + 2}
+\fBexpr\fR $b*4
+.CE
+.PP
+return 11, not a multiple of 4.
+This is because the Tcl parser will first substitute \fB$a + 2\fR for
+the variable \fBb\fR,
+then the \fBexpr\fR command will evaluate the expression \fB$a + 2*4\fR.
+.PP
+Most expressions do not require a second round of substitutions.
+Either they are enclosed in braces or, if not,
+their variable and command substitutions yield numbers or strings
+that do not themselves require substitutions.
+However, because a few unbraced expressions 
+need two rounds of substitutions,
+the bytecode compiler must emit
+additional instructions to handle this situation.
+The most expensive code is required for
+unbraced expressions that contain command substitutions.
+These expressions must be implemented by generating new code
+each time the expression is executed.
+When the expression is unbraced to allow the substitution of a function or
+operator, consider using the commands documented in the \fBmathfunc\fR(n) or
+\fBmathop\fR(n) manual pages directly instead.
+.SH EXAMPLES
+.PP
+Define a procedure that computes an
+.QW interesting
+mathematical function:
+.PP
+.CS
+proc tcl::mathfunc::calc {x y} {
+    \fBexpr\fR { ($x**2 - $y**2) / exp($x**2 + $y**2) }
+}
+.CE
+.PP
+Convert polar coordinates into cartesian coordinates:
+.PP
+.CS
+# convert from ($radius,$angle)
+set x [\fBexpr\fR { $radius * cos($angle) }]
+set y [\fBexpr\fR { $radius * sin($angle) }]
+.CE
+.PP
+Convert cartesian coordinates into polar coordinates:
+.PP
+.CS
+# convert from ($x,$y)
+set radius [\fBexpr\fR { hypot($y, $x) }]
+set angle  [\fBexpr\fR { atan2($y, $x) }]

+.SH SYNOPSIS
+\fBfblocked \fIchannelId\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+The \fBfblocked\fR command returns 1 if the most recent input operation
+on \fIchannelId\fR returned less information than requested because all
+available input was exhausted.
+For example, if \fBgets\fR is invoked when there are only three
+characters available for input and no end-of-line sequence, \fBgets\fR
+returns an empty string and a subsequent call to \fBfblocked\fR will
+return 1.
+.PP
+\fIChannelId\fR must be an identifier for an open channel such as a
+Tcl standard channel (\fBstdin\fR, \fBstdout\fR, or \fBstderr\fR),
+the return value from an invocation of \fBopen\fR or \fBsocket\fR, or
+the result of a channel creation command provided by a Tcl extension.
+.SH EXAMPLE
+The \fBfblocked\fR command is particularly useful when writing network
+servers, as it allows you to write your code in a line-by-line style
+without preventing the servicing of other connections.  This can be
+seen in this simple echo-service:
+.PP
+.CS
+# This is called whenever a new client connects to the server
+proc connect {chan host port} {
+    set clientName [format <%s:%d> $host $port]
+    puts "connection from $clientName"

+}
+
+# This is called whenever either at least one byte of input
+# data is available, or the channel was closed by the client.
+proc echoLine {chan clientName} {
+    gets $chan line
+    if {[eof $chan]} {
+        puts "finishing connection from $clientName"
+        close $chan
+    } elseif {![\fBfblocked\fR $chan]} {
+        # Didn't block waiting for end-of-line
+        puts "$clientName - $line"

+fconfigure \- Set and get options on a channel
+.SH SYNOPSIS
+.nf
+\fBfconfigure \fIchannelId\fR
+\fBfconfigure \fIchannelId\fR \fIname\fR
+\fBfconfigure \fIchannelId\fR \fIname value \fR?\fIname value ...\fR?
+.fi
+.BE
+.SH DESCRIPTION
+.PP
+The \fBfconfigure\fR command sets and retrieves options for channels.
+.PP
+\fIChannelId\fR identifies the channel for which to set or query an
+option and must refer to an open channel such as a Tcl standard
+channel (\fBstdin\fR, \fBstdout\fR, or \fBstderr\fR), the return
+value from an invocation of \fBopen\fR or \fBsocket\fR, or the result
+of a channel creation command provided by a Tcl extension.
+.PP
+If no \fIname\fR or \fIvalue\fR arguments are supplied, the command
+returns a list containing alternating option names and values for the channel.
+If \fIname\fR is supplied but no \fIvalue\fR then the command returns
+the current value of the given option.
+If one or more pairs of \fIname\fR and \fIvalue\fR are supplied, the
+command sets each of the named options to the corresponding \fIvalue\fR;
+in this case the return value is an empty string.
+.PP
+The options described below are supported for all channels. In addition,
+each channel type may add options that only it supports. See the manual
+entry for the command that creates each type of channels for the options
+that that specific type of channel supports. For example, see the manual
+entry for the \fBsocket\fR command for additional options for sockets, and
+the \fBopen\fR command for additional options for serial devices.
+.TP
+\fB\-blocking\fR \fIboolean\fR
+The \fB\-blocking\fR option determines whether I/O operations on the
+channel can cause the process to block indefinitely.
+The value of the option must be a proper boolean value.
+Channels are normally in blocking mode;  if a channel is placed into
+nonblocking mode it will affect the operation of the \fBgets\fR,
+\fBread\fR, \fBputs\fR, \fBflush\fR, and \fBclose\fR commands by
+allowing them to operate asynchronously;
+see the documentation for those commands for details.
+For nonblocking mode to work correctly, the application must be
+using the Tcl event loop (e.g. by calling \fBTcl_DoOneEvent\fR or
+invoking the \fBvwait\fR command).
+.TP
+\fB\-buffering\fR \fInewValue\fR
+.
+If \fInewValue\fR is \fBfull\fR then the I/O system will buffer output
+until its internal buffer is full or until the \fBflush\fR command is
+invoked. If \fInewValue\fR is \fBline\fR, then the I/O system will
+automatically flush output for the channel whenever a newline character
+is output. If \fInewValue\fR is \fBnone\fR, the I/O system will flush
+automatically after every output operation.  The default is for
+\fB\-buffering\fR to be set to \fBfull\fR except for channels that
+connect to terminal-like devices; for these channels the initial setting
+is \fBline\fR.  Additionally, \fBstdin\fR and \fBstdout\fR are
+initially set to \fBline\fR, and \fBstderr\fR is set to \fBnone\fR.
+.TP
+\fB\-buffersize\fR \fInewSize\fR
+.
+\fINewvalue\fR must be an integer; its value is used to set the size of
+buffers, in bytes, subsequently allocated for this channel to store input
+or output. \fINewvalue\fR must be between one and one million, allowing
+buffers of one to one million bytes in size.
+.TP
+\fB\-encoding\fR \fIname\fR
+.
+This option is used to specify the encoding of the channel, so that the data
+can be converted to and from Unicode for use in Tcl.  For instance, in
+order for Tcl to read characters from a Japanese file in \fBshiftjis\fR
+and properly process and display the contents, the encoding would be set
+to \fBshiftjis\fR.  Thereafter, when reading from the channel, the bytes in
+the Japanese file would be converted to Unicode as they are read.
+Writing is also supported \- as Tcl strings are written to the channel they
+will automatically be converted to the specified encoding on output.
+.RS
+.PP
+If a file contains pure binary data (for instance, a JPEG image), the
+encoding for the channel should be configured to be \fBbinary\fR.  Tcl
+will then assign no interpretation to the data in the file and simply read or
+write raw bytes.  The Tcl \fBbinary\fR command can be used to manipulate this
+byte-oriented data.  It is usually better to set the
+\fB\-translation\fR option to \fBbinary\fR when you want to transfer
+binary data, as this turns off the other automatic interpretations of
+the bytes in the stream as well.
+.PP
+The default encoding for newly opened channels is the same platform- and
+locale-dependent system encoding used for interfacing with the operating
+system, as returned by \fBencoding system\fR.
+.RE
+.TP
+\fB\-eofchar\fR \fIchar\fR
+.TP
+\fB\-eofchar\fR \fB{\fIinChar outChar\fB}\fR
+.
+This option supports DOS file systems that use Control-z (\ex1a) as an
+end of file marker.  If \fIchar\fR is not an empty string, then this
+character signals end-of-file when it is encountered during input.  For
+output, the end-of-file character is output when the channel is closed.
+If \fIchar\fR is the empty string, then there is no special end of file
+character marker.  For read-write channels, a two-element list specifies
+the end of file marker for input and output, respectively.  As a
+convenience, when setting the end-of-file character for a read-write
+channel you can specify a single value that will apply to both reading
+and writing.  When querying the end-of-file character of a read-write
+channel, a two-element list will always be returned.  The default value
+for \fB\-eofchar\fR is the empty string in all cases except for files
+under Windows.  In that case the \fB\-eofchar\fR is Control-z (\ex1a) for
+reading and the empty string for writing.
+The acceptable range for \fB\-eofchar\fR values is \ex01 - \ex7f;
+attempting to set \fB\-eofchar\fR to a value outside of this range will
+generate an error.
+.TP
+\fB\-translation\fR \fImode\fR
+.TP
+\fB\-translation\fR \fB{\fIinMode outMode\fB}\fR 
+.
+In Tcl scripts the end of a line is always represented using a single
+newline character (\en).  However, in actual files and devices the end of
+a line may be represented differently on different platforms, or even for
+different devices on the same platform.  For example, under UNIX newlines
+are used in files, whereas carriage-return-linefeed sequences are
+normally used in network connections.  On input (i.e., with \fBgets\fR
+and \fBread\fR) the Tcl I/O system automatically translates the external
+end-of-line representation into newline characters.  Upon output (i.e.,
+with \fBputs\fR), the I/O system translates newlines to the external
+end-of-line representation.  The default translation mode, \fBauto\fR,
+handles all the common cases automatically, but the \fB\-translation\fR
+option provides explicit control over the end of line translations.
+.RS
+.PP
+The value associated with \fB\-translation\fR is a single item for
+read-only and write-only channels.  The value is a two-element list for
+read-write channels; the read translation mode is the first element of
+the list, and the write translation mode is the second element.  As a
+convenience, when setting the translation mode for a read-write channel
+you can specify a single value that will apply to both reading and
+writing.  When querying the translation mode of a read-write channel, a
+two-element list will always be returned.  The following values are
+currently supported:
+.TP
+\fBauto\fR
+.
+As the input translation mode, \fBauto\fR treats any of newline
+(\fBlf\fR), carriage return (\fBcr\fR), or carriage return followed by a
+newline (\fBcrlf\fR) as the end of line representation.  The end of line
+representation can even change from line-to-line, and all cases are
+translated to a newline.  As the output translation mode, \fBauto\fR
+chooses a platform specific representation; for sockets on all platforms
+Tcl chooses \fBcrlf\fR, for all Unix flavors, it chooses \fBlf\fR, and
+for the various flavors of Windows it chooses \fBcrlf\fR.  The default
+setting for \fB\-translation\fR is \fBauto\fR for both input and output.
+.TP
+\fBbinary\fR 
+.
+No end-of-line translations are performed.  This is nearly identical to
+\fBlf\fR mode, except that in addition \fBbinary\fR mode also sets the
+end-of-file character to the empty string (which disables it) and sets the
+encoding to \fBbinary\fR (which disables encoding filtering).  See the
+description of \fB\-eofchar\fR and \fB\-encoding\fR for more information.
+.RS
+.PP
+Internally, i.e. when it comes to the actual behaviour of the
+translator this value \fBis\fR identical to \fBlf\fR and is therefore
+reported as such when queried. Even if \fBbinary\fR was used to set
+the translation.
+.RE
+.TP
+\fBcr\fR
+.
+The end of a line in the underlying file or device is represented by a
+single carriage return character.  As the input translation mode,
+\fBcr\fR mode converts carriage returns to newline characters.  As the
+output translation mode, \fBcr\fR mode translates newline characters to
+carriage returns.
+.TP
+\fBcrlf\fR
+.
+The end of a line in the underlying file or device is represented by a
+carriage return character followed by a linefeed character.  As the input
+translation mode, \fBcrlf\fR mode converts carriage-return-linefeed
+sequences to newline characters.  As the output translation mode,
+\fBcrlf\fR mode translates newline characters to carriage-return-linefeed
+sequences.  This mode is typically used on Windows platforms and for
+network connections.
+.TP
+\fBlf\fR

+The end of a line in the underlying file or device is represented by a

+fcopy \- Copy data from one channel to another
+.SH SYNOPSIS
+\fBfcopy \fIinchan\fR \fIoutchan\fR ?\fB\-size \fIsize\fR? ?\fB\-command \fIcallback\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+The \fBfcopy\fR command copies data from one I/O channel, \fIinchan\fR to another I/O channel, \fIoutchan\fR.
+The \fBfcopy\fR command leverages the buffering in the Tcl I/O system to
+avoid extra copies and to avoid buffering too much data in
+main memory when copying large files to slow destinations like
+network sockets.
+.PP
+The \fBfcopy\fR 
+command transfers data from \fIinchan\fR until end of file
+or \fIsize\fR bytes have been 
+transferred. If no \fB\-size\fR argument is given,
+then the copy goes until end of file.
+All the data read from \fIinchan\fR is copied to \fIoutchan\fR.
+Without the \fB\-command\fR option, \fBfcopy\fR blocks until the copy is complete
+and returns the number of bytes written to \fIoutchan\fR.
+.PP
+The \fB\-command\fR argument makes \fBfcopy\fR work in the background.
+In this case it returns immediately and the \fIcallback\fR is invoked
+later when the copy completes.
+The \fIcallback\fR is called with
+one or two additional 
+arguments that indicates how many bytes were written to \fIoutchan\fR.
+If an error occurred during the background copy, the second argument is the
+error string associated with the error.
+With a background copy,
+it is not necessary to put \fIinchan\fR or \fIoutchan\fR into
+non-blocking mode; the \fBfcopy\fR command takes care of that automatically.
+However, it is necessary to enter the event loop by using
+the \fBvwait\fR command or by using Tk.
+.PP
+You are not allowed to do other I/O operations with
+\fIinchan\fR or \fIoutchan\fR during a background \fBfcopy\fR.
+If either \fIinchan\fR or \fIoutchan\fR get closed
+while the copy is in progress, the current copy is stopped
+and the command callback is \fInot\fR made.
+If \fIinchan\fR is closed,
+then all data already queued for \fIoutchan\fR is written out.
+.PP
+Note that \fIinchan\fR can become readable during a background copy.
+You should turn off any \fBfileevent\fR handlers during a background
+copy so those handlers do not interfere with the copy.
+Any I/O attempted by a \fBfileevent\fR handler will get a
+.QW "channel busy"
+error.
+.PP
+\fBFcopy\fR translates end-of-line sequences in \fIinchan\fR and \fIoutchan\fR
+according to the \fB\-translation\fR option
+for these channels.
+See the manual entry for \fBfconfigure\fR for details on the
+\fB\-translation\fR option.
+The translations mean that the number of bytes read from \fIinchan\fR
+can be different than the number of bytes written to \fIoutchan\fR.
+Only the number of bytes written to \fIoutchan\fR is reported,
+either as the return value of a synchronous \fBfcopy\fR or
+as the argument to the callback for an asynchronous \fBfcopy\fR.
+.PP
+\fBFcopy\fR obeys the encodings and character translations configured
+for the channels. This
+means that the incoming characters are converted internally first
+UTF-8 and then into the encoding of the channel \fBfcopy\fR writes
+to. See the manual entry for \fBfconfigure\fR for details on the
+\fB\-encoding\fR and \fB\-translation\fR options. No conversion is
+done if both channels are
+set to encoding
+.QW binary
+and have matching translations. If only the output channel is set to encoding
+.QW binary
+the system will write the internal UTF-8 representation of the incoming
+characters. If only the input channel is set to encoding
+.QW binary
+the system will assume that the incoming
+bytes are valid UTF-8 characters and convert them according to the
+output encoding. The behaviour of the system for bytes which are not
+valid UTF-8 characters is undefined in this case.
+.SH EXAMPLES
+.PP
+The first example transfers the contents of one channel exactly to
+another. Note that when copying one file to another, it is better to
+use \fBfile copy\fR which also copies file metadata (e.g. the file
+access permissions) where possible.
+.PP
+.CS
+fconfigure $in -translation binary
+fconfigure $out -translation binary
+\fBfcopy\fR $in $out
+.CE
+.PP
+This second example shows how the callback gets
+passed the number of bytes transferred.
+It also uses vwait to put the application into the event loop.
+Of course, this simplified example could be done without the command 
+callback.
+.PP
+.CS
+proc Cleanup {in out bytes {error {}}} {
+    global total

+}
+set in [open $file1]
+set out [socket $server $port]
+\fBfcopy\fR $in $out -command [list Cleanup $in $out]
+vwait total
+.CE

+The third example copies in chunks and tests for end of file
+in the command callback.

+.SH SYNOPSIS
+\fBfile \fIoption\fR \fIname\fR ?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command provides several operations on a file's name or attributes.
+\fIName\fR is the name of a file; if it starts with a tilde, then tilde
+substitution is done before executing the command (see the manual entry for
+\fBfilename\fR for details).  \fIOption\fR indicates what to do with the
+file name.  Any unique abbreviation for \fIoption\fR is acceptable.  The
+valid options are:
+.TP
+\fBfile atime \fIname\fR ?\fBtime\fR?
+.
+Returns a decimal string giving the time at which file \fIname\fR was last
+accessed.  If \fItime\fR is specified, it is an access time to set
+for the file.  The time is measured in the standard POSIX fashion as
+seconds from a fixed starting time (often January 1, 1970).  If the file
+does not exist or its access time cannot be queried or set then an error is
+generated.  On Windows, FAT file systems do not support access time.
+.TP
+\fBfile attributes \fIname\fR
+.TP
+\fBfile attributes \fIname\fR ?\fBoption\fR?
+.TP
+\fBfile attributes \fIname\fR ?\fBoption value option value...\fR?
+.
+This subcommand returns or sets platform specific values associated
+with a file. The first form returns a list of the platform specific
+flags and their values. The second form returns the value for the
+specific option. The third form sets one or more of the values. The
+values are as follows:
+.RS
+.PP
+On Unix, \fB\-group\fR gets or sets the group name for the file. A group id
+can be given to the command, but it returns a group name. \fB\-owner\fR gets
+or sets the user name of the owner of the file. The command returns the
+owner name, but the numerical id can be passed when setting the
+owner. \fB\-permissions\fR sets or retrieves the octal code that chmod(1)
+uses.  This command does also has limited support for setting using the
+symbolic attributes for chmod(1), of the form [ugo]?[[+\-=][rwxst],[...]],
+where multiple symbolic attributes can be separated by commas (example:
+\fBu+s,go\-rw\fR add sticky bit for user, remove read and write
+permissions for group and other).  A simplified \fBls\fR style string,
+of the form rwxrwxrwx (must be 9 characters), is also supported
+(example: \fBrwxr\-xr\-t\fR is equivalent to 01755).
+On versions of Unix supporting file flags, \fB\-readonly\fR gives the
+value or sets or clears the readonly attribute of the file,
+i.e. the user immutable flag \fBuchg\fR to chflags(1).
+.PP
+On Windows, \fB\-archive\fR gives the value or sets or clears the
+archive attribute of the file. \fB\-hidden\fR gives the value or sets
+or clears the hidden attribute of the file. \fB\-longname\fR will
+expand each path element to its long version. This attribute cannot be
+set. \fB\-readonly\fR gives the value or sets or clears the readonly
+attribute of the file. \fB\-shortname\fR gives a string where every
+path element is replaced with its short (8.3) version of the
+name. This attribute cannot be set. \fB\-system\fR gives or sets or
+clears the value of the system attribute of the file.
+.PP
+On Mac OS X and Darwin, \fB\-creator\fR gives or sets the
+Finder creator type of the file. \fB\-hidden\fR gives or sets or clears
+the hidden attribute of the file. \fB\-readonly\fR gives or sets or
+clears the readonly attribute of the file. \fB\-rsrclength\fR gives
+the length of the resource fork of the file, this attribute can only be
+set to the value 0, which results in the resource fork being stripped
+off the file.
+.RE
+.TP
+\fBfile channels ?\fIpattern\fR?
+.
+If \fIpattern\fR is not specified, returns a list of names of all
+registered open channels in this interpreter.  If \fIpattern\fR is
+specified, only those names matching \fIpattern\fR are returned.  Matching
+is determined using the same rules as for \fBstring match\fR.
+.TP
+\fBfile copy \fR?\fB\-force\fR? ?\fB\-\|\-\fR? \fIsource\fR \fItarget\fR
+.TP
+\fBfile copy \fR?\fB\-force\fR? ?\fB\-\|\-\fR? \fIsource\fR ?\fIsource\fR ...? \fItargetDir\fR
+.
+The first form makes a copy of the file or directory \fIsource\fR under
+the pathname \fItarget\fR. If \fItarget\fR is an existing directory,
+then the second form is used.  The second form makes a copy inside
+\fItargetDir\fR of each \fIsource\fR file listed.  If a directory is
+specified as a \fIsource\fR, then the contents of the directory will be
+recursively copied into \fItargetDir\fR. Existing files will not be
+overwritten unless the \fB\-force\fR option is specified (when Tcl will
+also attempt to adjust permissions on the destination file or directory
+if that is necessary to allow the copy to proceed).  When copying
+within a single filesystem, \fIfile copy\fR will copy soft links (i.e.
+the links themselves are copied, not the things they point to).  Trying
+to overwrite a non-empty directory, overwrite a directory with a file,
+or overwrite a file with a directory will all result in errors even if
+\fB\-force\fR was specified.  Arguments are processed in the order
+specified, halting at the first error, if any.  A \fB\-\|\-\fR marks
+the end of switches; the argument following the \fB\-\|\-\fR will be
+treated as a \fIsource\fR even if it starts with a \fB\-\fR.
+.TP
+\fBfile delete \fR?\fB\-force\fR? ?\fB\-\|\-\fR? ?\fIpathname\fR ... ?
+.
+Removes the file or directory specified by each \fIpathname\fR
+argument.  Non-empty directories will be removed only if the
+\fB\-force\fR option is specified.  When operating on symbolic links,
+the links themselves will be deleted, not the objects they point to.
+Trying to delete a non-existent file is not considered an error.
+Trying to delete a read-only file will cause the file to be deleted,
+even if the \fB\-force\fR flags is not specified.  If the \fB\-force\fR
+option is specified on a directory, Tcl will attempt both to change
+permissions and move the current directory
+.QW pwd
+out of the given path if that is necessary to allow the deletion to
+proceed.  Arguments are processed in the order specified, halting at
+the first error, if any.
+A \fB\-\|\-\fR marks the end of switches; the argument following the
+\fB\-\|\-\fR will be treated as a \fIpathname\fR even if it starts with
+a \fB\-\fR.
+.TP
+\fBfile dirname \fIname\fR
+Returns a name comprised of all of the path components in \fIname\fR
+excluding the last element.  If \fIname\fR is a relative file name and
+only contains one path element, then returns
+.QW \fB.\fR .
+If \fIname\fR refers to a root directory, then the root directory is
+returned.  For example,
+.RS
+.PP
+.CS
+\fBfile dirname\fR c:/
+.CE
+.PP
+returns \fBc:/\fR. 
+.PP
+Note that tilde substitution will only be
+performed if it is necessary to complete the command. For example,
+.PP
+.CS
+\fBfile dirname\fR ~/src/foo.c
+.CE
+.PP
+returns \fB~/src\fR, whereas
+.PP
+.CS
+\fBfile dirname\fR ~
+.CE
+.PP
+returns \fB/home\fR (or something similar).
+.RE
+.TP
+\fBfile executable \fIname\fR
+.
+Returns \fB1\fR if file \fIname\fR is executable by the current user,
+\fB0\fR otherwise.  
+.TP
+\fBfile exists \fIname\fR
+.
+Returns \fB1\fR if file \fIname\fR exists and the current user has
+search privileges for the directories leading to it, \fB0\fR otherwise.
+.TP
+\fBfile extension \fIname\fR
+.
+Returns all of the characters in \fIname\fR after and including the last
+dot in the last element of \fIname\fR.  If there is no dot in the last
+element of \fIname\fR then returns the empty string.
+.TP
+\fBfile isdirectory \fIname\fR
+.
+Returns \fB1\fR if file \fIname\fR is a directory, \fB0\fR otherwise.
+.TP
+\fBfile isfile \fIname\fR
+.
+Returns \fB1\fR if file \fIname\fR is a regular file, \fB0\fR otherwise.
+.TP
+\fBfile join \fIname\fR ?\fIname ...\fR?
+.
+Takes one or more file names and combines them, using the correct path
+separator for the current platform.  If a particular \fIname\fR is
+relative, then it will be joined to the previous file name argument.
+Otherwise, any earlier arguments will be discarded, and joining will
+proceed from the current argument.  For example,
+.RS
+.PP
+.CS
+\fBfile join\fR a b /foo bar
+.CE
+.PP
+returns \fB/foo/bar\fR.
+.PP
+Note that any of the names can contain separators, and that the result
+is always canonical for the current platform: \fB/\fR for Unix and
+Windows.
+.RE
+.TP
+\fBfile link ?\fI\-linktype\fR? \fIlinkName\fR ?\fItarget\fR?
+.
+If only one argument is given, that argument is assumed to be
+\fIlinkName\fR, and this command returns the value of the link given by
+\fIlinkName\fR (i.e. the name of the file it points to).  If
+\fIlinkName\fR is not a link or its value cannot be read (as, for example,
+seems to be the case with hard links, which look just like ordinary
+files), then an error is returned.
+.RS
+.PP
+If 2 arguments are given, then these are assumed to be \fIlinkName\fR
+and \fItarget\fR. If \fIlinkName\fR already exists, or if \fItarget\fR
+does not exist, an error will be returned.  Otherwise, Tcl creates a new
+link called \fIlinkName\fR which points to the existing filesystem
+object at \fItarget\fR (which is also the returned value), where the
+type of the link is platform-specific (on Unix a symbolic link will be
+the default).  This is useful for the case where the user wishes to
+create a link in a cross-platform way, and does not care what type of
+link is created.
+.PP
+If the user wishes to make a link of a specific type only, (and signal an
+error if for some reason that is not possible), then the optional
+\fI\-linktype\fR argument should be given.  Accepted values for
+\fI\-linktype\fR are
+.QW \fB\-symbolic\fR
+and
+.QW \fB\-hard\fR .
+.PP
+On Unix, symbolic links can be made to relative paths, and those paths
+must be relative to the actual \fIlinkName\fR's location (not to the
+cwd), but on all other platforms where relative links are not supported,
+target paths will always be converted to absolute, normalized form
+before the link is created (and therefore relative paths are interpreted
+as relative to the cwd).  Furthermore,
+.QW ~user
+paths are always expanded
+to absolute form.  When creating links on filesystems that either do not
+support any links, or do not support the specific type requested, an
+error message will be returned.  In particular Windows 95, 98 and ME do
+not support any links at present, but most Unix platforms support both
+symbolic and hard links (the latter for files only) and Windows
+NT/2000/XP (on NTFS drives) support symbolic
+directory links and hard file links.
+.RE
+.TP
+\fBfile lstat \fIname varName\fR
+.
+Same as \fBstat\fR option (see below) except uses the \fIlstat\fR
+kernel call instead of \fIstat\fR.  This means that if \fIname\fR
+refers to a symbolic link the information returned in \fIvarName\fR
+is for the link rather than the file it refers to.  On systems that
+do not support symbolic links this option behaves exactly the same
+as the \fBstat\fR option.
+.TP
+\fBfile mkdir ?\fIdir\fR ...?
+.
+Creates each directory specified.  For each pathname \fIdir\fR specified,
+this command will create all non-existing parent directories as
+well as \fIdir\fR itself.  If an existing directory is specified, then
+no action is taken and no error is returned.  Trying to overwrite an existing
+file with a directory will result in an error.  Arguments are processed in
+the order specified, halting at the first error, if any.
+.TP
+\fBfile mtime \fIname\fR ?\fItime\fR?
+.
+Returns a decimal string giving the time at which file \fIname\fR was last
+modified.  If \fItime\fR is specified, it is a modification time to set for
+the file (equivalent to Unix \fBtouch\fR).  The time is measured in the
+standard POSIX fashion as seconds from a fixed starting time (often January
+1, 1970).  If the file does not exist or its modified time cannot be queried
+or set then an error is generated.
+.TP
+\fBfile nativename \fIname\fR
+.
+Returns the platform-specific name of the file. This is useful if the
+filename is needed to pass to a platform-specific call, such as to a
+subprocess via \fBexec\fR under Windows (see \fBEXAMPLES\fR below).
+.TP
+\fBfile normalize \fIname\fR
+.
+Returns a unique normalized path representation for the file-system
+object (file, directory, link, etc), whose string value can be used as a
+unique identifier for it.  A normalized path is an absolute path which has
+all
+.QW ../
+and
+.QW ./
+removed.  Also it is one which is in the
+.QW standard
+format for the native platform.  On Unix, this means the segments
+leading up to the path must be free of symbolic links/aliases (but the
+very last path component may be a symbolic link), and on Windows it also
+means we want the long form with that form's case-dependence (which
+gives us a unique, case-dependent path).  The one exception concerning the
+last link in the path is necessary, because Tcl or the user may wish to
+operate on the actual symbolic link itself (for example \fBfile delete\fR,
+\fBfile rename\fR, \fBfile copy\fR are defined to operate on symbolic
+links, not on the things that they point to).
+.TP
+\fBfile owned \fIname\fR 
+.
+Returns \fB1\fR if file \fIname\fR is owned by the current user, \fB0\fR
+otherwise.
+.TP
+\fBfile pathtype \fIname\fR
+.
+Returns one of \fBabsolute\fR, \fBrelative\fR, \fBvolumerelative\fR. If
+\fIname\fR refers to a specific file on a specific volume, the path type will
+be \fBabsolute\fR. If \fIname\fR refers to a file relative to the current
+working directory, then the path type will be \fBrelative\fR. If \fIname\fR
+refers to a file relative to the current working directory on a specified
+volume, or to a specific file on the current working volume, then the path
+type is \fBvolumerelative\fR.
+.TP
+\fBfile readable \fIname\fR
+.
+Returns \fB1\fR if file \fIname\fR is readable by the current user,
+\fB0\fR otherwise. 
+.TP
+\fBfile readlink \fIname\fR
+.
+Returns the value of the symbolic link given by \fIname\fR (i.e. the name
+of the file it points to).  If \fIname\fR is not a symbolic link or its
+value cannot be read, then an error is returned.  On systems that do not
+support symbolic links this option is undefined.
+.TP
+\fBfile rename \fR?\fB\-force\fR? ?\fB\-\|\-\fR? \fIsource\fR \fItarget\fR
+.TP
+\fBfile rename \fR?\fB\-force\fR? ?\fB\-\|\-\fR? \fIsource\fR ?\fIsource\fR ...? \fItargetDir\fR
+.
+The first form takes the file or directory specified by pathname
+\fIsource\fR and renames it to \fItarget\fR, moving the file if the
+pathname \fItarget\fR specifies a name in a different directory.  If
+\fItarget\fR is an existing directory, then the second form is used.
+The second form moves each \fIsource\fR file or directory into the
+directory \fItargetDir\fR. Existing files will not be overwritten
+unless the \fB\-force\fR option is specified.  When operating inside a
+single filesystem, Tcl will rename symbolic links rather than the
+things that they point to.  Trying to overwrite a non-empty directory,
+overwrite a directory with a file, or a file with a directory will all
+result in errors.  Arguments are processed in the order specified,
+halting at the first error, if any.  A \fB\-\|\-\fR marks the end of
+switches; the argument following the \fB\-\|\-\fR will be treated as a
+\fIsource\fR even if it starts with a \fB\-\fR.

+\fBfile rootname \fIname\fR

+character in the last component of name.  If the last
+component of \fIname\fR does not contain a dot, then returns \fIname\fR.
+.TP
+\fBfile separator\fR ?\fIname\fR?
+.
+If no argument is given, returns the character which is used to separate 
+path segments for native files on this platform.  If a path is given,
+the filesystem responsible for that path is asked to return its
+separator character.  If no file system accepts \fIname\fR, an error
+is generated.

+\fBfile split \fIname\fR
+.
+Returns a list whose elements are the path components in \fIname\fR.  The
+first element of the list will have the same path type as \fIname\fR.
+All other elements will be relative.  Path separators will be discarded
+unless they are needed to ensure that an element is unambiguously relative.
+For example, under Unix
+.RS
+.PP
+.CS
+\fBfile split\fR /foo/~bar/baz
+.CE
+.PP
+returns
+.QW \fB/\0\0foo\0\0./~bar\0\0baz\fR
+to ensure that later commands
+that use the third component do not attempt to perform tilde
+substitution.
+.RE
+.TP
+\fBfile stat  \fIname varName\fR
+.
+Invokes the \fBstat\fR kernel call on \fIname\fR, and uses the variable
+given by \fIvarName\fR to hold information returned from the kernel call.
+\fIVarName\fR is treated as an array variable, and the following elements
+of that variable are set: \fBatime\fR, \fBctime\fR, \fBdev\fR, \fBgid\fR,
+\fBino\fR, \fBmode\fR, \fBmtime\fR, \fBnlink\fR, \fBsize\fR, \fBtype\fR,
+\fBuid\fR.  Each element except \fBtype\fR is a decimal string with the
+value of the corresponding field from the \fBstat\fR return structure;
+see the manual entry for \fBstat\fR for details on the meanings of the
+values.  The \fBtype\fR element gives the type of the file in the same
+form returned by the command \fBfile type\fR.  This command returns an
+empty string.
+.TP
+\fBfile system \fIname\fR
+.
+Returns a list of one or two elements, the first of which is the name of
+the filesystem to use for the file, and the second, if given, an
+arbitrary string representing the filesystem-specific nature or type of
+the location within that filesystem.  If a filesystem only supports one
+type of file, the second element may not be supplied.  For example the
+native files have a first element
+.QW native ,
+and a second element which when given is a platform-specific type name
+for the file's system (e.g.
+.QW NTFS ,
+.QW FAT ,
+on Windows).  A generic virtual file system might return
+the list
+.QW "vfs ftp"
+to represent a file on a remote ftp site mounted as a
+virtual filesystem through an extension called
+.QW vfs .
+If the file does not belong to any filesystem, an error is generated.

+\fBfile tail \fIname\fR
+.
+Returns all of the characters in the last filesystem component of
+\fIname\fR.  Any trailing directory separator in \fIname\fR is ignored.
+If \fIname\fR contains no separators then returns \fIname\fR.  So, 
+\fBfile tail a/b\fR, \fBfile tail a/b/\fR and \fBfile tail b\fR all

+fileevent \- Execute a script when a channel becomes readable or writable
+.SH SYNOPSIS
+\fBfileevent \fIchannelId \fBreadable \fR?\fIscript\fR?
+.sp
+\fBfileevent \fIchannelId \fBwritable \fR?\fIscript\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command is used to create \fIfile event handlers\fR.  A file event
+handler is a binding between a channel and a script, such that the script
+is evaluated whenever the channel becomes readable or writable.  File event
+handlers are most commonly used to allow data to be received from another
+process on an event-driven basis, so that the receiver can continue to
+interact with the user while waiting for the data to arrive.  If an
+application invokes \fBgets\fR or \fBread\fR on a blocking channel when
+there is no input data available, the process will block; until the input
+data arrives, it will not be able to service other events, so it will
+appear to the user to
+.QW "freeze up" .
+With \fBfileevent\fR, the process can
+tell when data is present and only invoke \fBgets\fR or \fBread\fR when
+they will not block.
+.PP
+The \fIchannelId\fR argument to \fBfileevent\fR refers to an open
+channel such as a Tcl standard channel (\fBstdin\fR, \fBstdout\fR,
+or \fBstderr\fR), the return value from an invocation of \fBopen\fR
+or \fBsocket\fR, or the result of a channel creation command provided
+by a Tcl extension.
+.PP
+If the \fIscript\fR argument is specified, then \fBfileevent\fR
+creates a new event handler:  \fIscript\fR will be evaluated
+whenever the channel becomes readable or writable (depending on the
+second argument to \fBfileevent\fR).
+In this case \fBfileevent\fR returns an empty string.
+The \fBreadable\fR and \fBwritable\fR event handlers for a file
+are independent, and may be created and deleted separately.
+However, there may be at most one \fBreadable\fR and one \fBwritable\fR
+handler for a file at a given time in a given interpreter.
+If \fBfileevent\fR is called when the specified handler already
+exists in the invoking interpreter, the new script replaces the old one.
+.PP
+If the \fIscript\fR argument is not specified, \fBfileevent\fR
+returns the current script for \fIchannelId\fR, or an empty string
+if there is none.
+If the \fIscript\fR argument is specified as an empty string
+then the event handler is deleted, so that no script will be invoked.
+A file event handler is also deleted automatically whenever
+its channel is closed or its interpreter is deleted.
+.PP
+A channel is considered to be readable if there is unread data
+available on the underlying device.
+A channel is also considered to be readable if there is unread
+data in an input buffer, except in the special case where the
+most recent attempt to read from the channel was a \fBgets\fR
+call that could not find a complete line in the input buffer.
+This feature allows a file to be read a line at a time in nonblocking mode
+using events.
+A channel is also considered to be readable if an end of file or
+error condition is present on the underlying file or device.
+It is important for \fIscript\fR to check for these conditions
+and handle them appropriately;  for example, if there is no special
+check for end of file, an infinite loop may occur where \fIscript\fR
+reads no data, returns, and is immediately invoked again.
+.PP
+A channel is considered to be writable if at least one byte of data
+can be written to the underlying file or device without blocking,
+or if an error condition is present on the underlying file or device.
+.PP
+Event-driven I/O works best for channels that have been placed into
+nonblocking mode with the \fBfconfigure\fR command.  In blocking mode,
+a \fBputs\fR command may block if you give it more data than the
+underlying file or device can accept, and a \fBgets\fR or \fBread\fR
+command will block if you attempt to read more data than is ready; a
+readable underlying file or device may not even guarantee that a
+blocking [read 1] will succeed (counter-examples being multi-byte
+encodings, compression or encryption transforms ). In all such cases,
+no events will be processed while the commands block.
+.PP
+In nonblocking mode \fBputs\fR, \fBread\fR, and \fBgets\fR never block.
+See the documentation for the individual commands for information
+on how they handle blocking and nonblocking channels.
+.PP
+Testing for the end of file condition should be done after any attempts
+read the channel data. The eof flag is set once an attempt to read the
+end of data has occurred and testing before this read will require an
+additional event to be fired.
+.PP
+The script for a file event is executed at global level (outside the
+context of any Tcl procedure) in the interpreter in which the
+\fBfileevent\fR command was invoked.
+If an error occurs while executing the script then the
+command registered with \fBinterp bgerror\fR is used to report the error.
+In addition, the file event handler is deleted if it ever returns
+an error;  this is done in order to prevent infinite loops due to
+buggy handlers.
+.SH EXAMPLE
+.PP
+In this setup \fBGetData\fR will be called with the channel as an
+argument whenever $chan becomes readable. The \fBread\fR call will
+read whatever binary data is currently available without blocking.
+Here the channel has the fileevent removed when an end of file 
+occurs to avoid being continually called (see above). Alternatively
+the channel may be closed on this condition.
+.PP
+.CS

+    set data [read $chan]

+.SH NAME
+filename \- File name conventions supported by Tcl commands
+.BE
+.SH INTRODUCTION
+.PP
+All Tcl commands and C procedures that take file names as arguments
+expect the file names to be in one of three forms, depending on the
+current platform.  On each platform, Tcl supports file names in the
+standard forms(s) for that platform.  In addition, on all platforms,
+Tcl supports a Unix-like syntax intended to provide a convenient way
+of constructing simple file names.  However, scripts that are intended
+to be portable should not assume a particular form for file names.
+Instead, portable scripts must use the \fBfile split\fR and \fBfile
+join\fR commands to manipulate file names (see the \fBfile\fR manual
+entry for more details).
+.SH "PATH TYPES"
+.PP
+File names are grouped into three general types based on the starting point
+for the path used to specify the file: absolute, relative, and
+volume-relative.  Absolute names are completely qualified, giving a path to
+the file relative to a particular volume and the root directory on that
+volume.  Relative names are unqualified, giving a path to the file relative 
+to the current working directory.  Volume-relative names are partially
+qualified, either giving the path relative to the root directory on the
+current volume, or relative to the current directory of the specified
+volume.  The \fBfile pathtype\fR command can be used to determine the
+type of a given path.
+.SH "PATH SYNTAX"
+.PP
+The rules for native names depend on the value reported in the Tcl
+\fBplatform\fR element of the \fBtcl_platform\fR array:
+.TP 10
+\fBUnix\fR
+On Unix and Apple MacOS X platforms, Tcl uses path names where the
+components are separated by slashes.  Path names may be relative or
+absolute, and file names may contain any character other than slash.
+The file names \fB\&.\fR and \fB\&..\fR are special and refer to the
+current directory and the parent of the current directory respectively.
+Multiple adjacent slash characters are interpreted as a single
+separator.  Any number of trailing slash characters at the end of a
+path are simply ignored, so the paths \fBfoo\fR, \fBfoo/\fR and
+\fBfoo//\fR are all identical, and in particular \fBfoo/\fR does not
+necessarily mean a directory is being referred.
+.RS
+.PP
+The following examples illustrate various forms of path
+names:
+.TP 15
+\fB/\fR
+Absolute path to the root directory.
+.TP 15
+\fB/etc/passwd\fR
+Absolute path to the file named \fBpasswd\fR in the directory
+\fBetc\fR in the root directory.
+.TP 15
+\fB\&.\fR
+Relative path to the current directory.
+.TP 15
+\fBfoo\fR
+Relative path to the file \fBfoo\fR in the current directory.
+.TP 15
+\fBfoo/bar\fR
+Relative path to the file \fBbar\fR in the directory \fBfoo\fR in the
+current directory.
+.TP 15
+\fB\&../foo\fR
+Relative path to the file \fBfoo\fR in the directory above the current
+directory. 
+.RE
+.TP
+\fBWindows\fR
+On Microsoft Windows platforms, Tcl supports both drive-relative and UNC
+style names.  Both \fB/\fR and \fB\e\fR may be used as directory separators
+in either type of name.  Drive-relative names consist of an optional drive
+specifier followed by an absolute or relative path.  UNC paths follow the
+general form \fB\e\eservername\esharename\epath\efile\fR, but must at
+the very least contain the server and share components, i.e. 
+\fB\e\eservername\esharename\fR.  In both forms,
+the file names \fB.\fR and \fB..\fR are special and refer to the current
+directory and the parent of the current directory respectively.  The
+following examples illustrate various forms of path names:
+.RS
+.TP 15
+\fB\&\e\eHost\eshare/file\fR
+Absolute UNC path to a file called \fBfile\fR in the root directory of
+the export point \fBshare\fR on the host \fBHost\fR.  Note that
+repeated use of \fBfile dirname\fR on this path will give
+\fB//Host/share\fR, and will never give just \fB//Host\fR.
+.TP 15
+\fBc:foo\fR
+Volume-relative path to a file \fBfoo\fR in the current directory on drive
+\fBc\fR.
+.TP 15
+\fBc:/foo\fR
+Absolute path to a file \fBfoo\fR in the root directory of drive
+\fBc\fR.
+.TP 15

+extra backslashes are superfluous.
+.RE
+.SH "TILDE SUBSTITUTION"
+.PP
+In addition to the file name rules described above, Tcl also supports
+\fIcsh\fR-style tilde substitution.  If a file name starts with a tilde,
+then the file name will be interpreted as if the first element is
+replaced with the location of the home directory for the given user.  If
+the tilde is followed immediately by a separator, then the \fB$HOME\fR
+environment variable is substituted.  Otherwise the characters between
+the tilde and the next separator are taken as a user name, which is used
+to retrieve the user's home directory for substitution.  This works on
+Unix, MacOS X and Windows (except very old releases).
+.PP
+Old Windows platforms do not support tilde substitution when a user name
+follows the tilde.  On these platforms, attempts to use a tilde followed
+by a user name will generate an error that the user does not exist when
+Tcl attempts to interpret that part of the path or otherwise access the
+file.  The behaviour of these paths when not trying to interpret them is
+the same as on Unix.  File names that have a tilde without a user name
+will be correctly substituted using the \fB$HOME\fR environment
+variable, just like for Unix.
+.SH "PORTABILITY ISSUES"
+.PP
+Not all file systems are case sensitive, so scripts should avoid code
+that depends on the case of characters in a file name.  In addition,
+the character sets allowed on different devices may differ, so scripts
+should choose file names that do not contain special characters like:
+\fB<>:?"/\e|\fR.
+'\""\" reset emacs highlighting
+The safest approach is to use names consisting of
+alphanumeric characters only.  Care should be taken with filenames
+which contain spaces (common on Windows systems) and
+filenames where the backslash is the directory separator (Windows
+native path names).  Also Windows 3.1 only supports file
+names with a root of no more than 8 characters and an extension of no
+more than 3 characters.
+.PP
+On Windows platforms there are file and path length restrictions. 
+Complete paths or filenames longer than about 260 characters will lead
+to errors in most file operations.
+.PP
+Another Windows peculiarity is that any number of trailing dots
+.QW .
+in filenames are totally ignored, so, for example, attempts to create a
+file or directory with a name
+.QW foo.
+will result in the creation of a file/directory with name
+.QW foo .
+This fact is reflected in the results of \fBfile normalize\fR.
+Furthermore, a file name consisting only of dots
+.QW .........
+or dots with trailing characters
+.QW .....abc
+is illegal.

+.SH SYNOPSIS
+\fBflush \fIchannelId\fR
+.BE
+.SH DESCRIPTION
+.PP
+Flushes any output that has been buffered for \fIchannelId\fR.
+.PP
+\fIChannelId\fR must be an identifier for an open channel such as a
+Tcl standard channel (\fBstdout\fR or \fBstderr\fR), the return
+value from an invocation of \fBopen\fR or \fBsocket\fR, or the result
+of a channel creation command provided by a Tcl extension.  The
+channel must have been opened for writing.
+.PP
+If the channel is in blocking mode the command does not return until all the
+buffered output has been flushed to the channel. If the channel is in
+nonblocking mode, the command may return before all buffered output has been
+flushed; the remainder will be flushed in the background as fast as the
+underlying file or device is able to absorb it.

+.SH NAME
+for \- 'For' loop
+.SH SYNOPSIS
+\fBfor \fIstart test next body\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+\fBFor\fR is a looping command, similar in structure to the C
+\fBfor\fR statement.  The \fIstart\fR, \fInext\fR, and
+\fIbody\fR arguments must be Tcl command strings, and \fItest\fR
+is an expression string.
+The \fBfor\fR command first invokes the Tcl interpreter to
+execute \fIstart\fR.  Then it repeatedly evaluates \fItest\fR as
+an expression; if the result is non-zero it invokes the Tcl
+interpreter on \fIbody\fR, then invokes the Tcl interpreter on \fInext\fR,
+then repeats the loop.  The command terminates when \fItest\fR evaluates
+to 0.  If a \fBcontinue\fR command is invoked within \fIbody\fR then
+any remaining commands in the current execution of \fIbody\fR are skipped;
+processing continues by invoking the Tcl interpreter on \fInext\fR, then
+evaluating \fItest\fR, and so on.  If a \fBbreak\fR command is invoked
+within \fIbody\fR
+or \fInext\fR,
+then the \fBfor\fR command will
+return immediately.
+The operation of \fBbreak\fR and \fBcontinue\fR are similar to the
+corresponding statements in C.
+\fBFor\fR returns an empty string.
+.PP
+Note: \fItest\fR should almost always be enclosed in braces.  If not,
+variable substitutions will be made before the \fBfor\fR
+command starts executing, which means that variable changes
+made by the loop body will not be considered in the expression.
+This is likely to result in an infinite loop.  If \fItest\fR is
+enclosed in braces, variable substitutions are delayed until the
+expression is evaluated (before
+each loop iteration), so changes in the variables will be visible.
+See below for an example:
+.SH EXAMPLES
+.PP
+Print a line for each of the integers from 0 to 10:
+.PP
+.CS
+\fBfor\fR {set x 0} {$x<10} {incr x} {
+    puts "x is $x"
+}
+.CE
+.PP
+Either loop infinitely or not at all because the expression being
+evaluated is actually the constant, or even generate an error!  The
+actual behaviour will depend on whether the variable \fIx\fR exists
+before the \fBfor\fR command is run and whether its value is a value
+that is less than or greater than/equal to ten, and this is because
+the expression will be substituted before the \fBfor\fR command is
+executed.
+.PP

+\fBforeach \fIvarlist1 list1\fR ?\fIvarlist2 list2 ...\fR? \fIbody\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+The \fBforeach\fR command implements a loop where the loop
+variable(s) take on values from one or more lists.
+In the simplest case there is one loop variable, \fIvarname\fR,
+and one list, \fIlist\fR, that is a list of values to assign to \fIvarname\fR.
+The \fIbody\fR argument is a Tcl script.
+For each element of \fIlist\fR (in order
+from first to last), \fBforeach\fR assigns the contents of the
+element to \fIvarname\fR as if the \fBlindex\fR command had been used
+to extract the element, then calls the Tcl interpreter to execute
+\fIbody\fR.
+.PP
+In the general case there can be more than one value list
+(e.g., \fIlist1\fR and \fIlist2\fR),
+and each value list can be associated with a list of loop variables
+(e.g., \fIvarlist1\fR and \fIvarlist2\fR).
+During each iteration of the loop
+the variables of each \fIvarlist\fR are assigned
+consecutive values from the corresponding \fIlist\fR.
+Values in each \fIlist\fR are used in order from first to last,
+and each value is used exactly once.
+The total number of loop iterations is large enough to use
+up all the values from all the value lists.
+If a value list does not contain enough
+elements for each of its loop variables in each iteration,
+empty values are used for the missing elements.
+.PP
+The \fBbreak\fR and \fBcontinue\fR statements may be
+invoked inside \fIbody\fR, with the same effect as in the \fBfor\fR
+command.  \fBForeach\fR returns an empty string.

+.SH NAME
+format \- Format a string in the style of sprintf
+.SH SYNOPSIS
+\fBformat \fIformatString \fR?\fIarg arg ...\fR?
+.BE
+
+.SH INTRODUCTION
+.PP
+This command generates a formatted string in a fashion similar to the
+ANSI C \fBsprintf\fR procedure.
+\fIFormatString\fR indicates how to format the result, using
+\fB%\fR conversion specifiers as in \fBsprintf\fR, and the additional
+arguments, if any, provide values to be substituted into the result.
+The return value from \fBformat\fR is the formatted string.
+.SH "DETAILS ON FORMATTING"
+.PP
+The command operates by scanning \fIformatString\fR from left to right. 
+Each character from the format string is appended to the result
+string unless it is a percent sign.
+If the character is a \fB%\fR then it is not copied to the result string.
+Instead, the characters following the \fB%\fR character are treated as
+a conversion specifier.
+The conversion specifier controls the conversion of the next successive
+\fIarg\fR to a particular format and the result is appended to 
+the result string in place of the conversion specifier.
+If there are multiple conversion specifiers in the format string,
+then each one controls the conversion of one additional \fIarg\fR.
+The \fBformat\fR command must be given enough \fIarg\fRs to meet the needs
+of all of the conversion specifiers in \fIformatString\fR.
+.PP
+Each conversion specifier may contain up to six different parts:
+an XPG3 position specifier,
+a set of flags, a minimum field width, a precision, a size modifier,
+and a conversion character.
+Any of these fields may be omitted except for the conversion character.
+The fields that are present must appear in the order given above.
+The paragraphs below discuss each of these fields in turn.
+.SS "OPTIONAL POSITIONAL SPECIFIER"
+.PP
+If the \fB%\fR is followed by a decimal number and a \fB$\fR, as in
+.QW \fB%2$d\fR ,
+then the value to convert is not taken from the next sequential argument.
+Instead, it is taken from the argument indicated by the number,
+where 1 corresponds to the first \fIarg\fR.
+If the conversion specifier requires multiple arguments because
+of \fB*\fR characters in the specifier then
+successive arguments are used, starting with the argument
+given by the number.
+This follows the XPG3 conventions for positional specifiers.
+If there are any positional specifiers in \fIformatString\fR
+then all of the specifiers must be positional.
+.SS "OPTIONAL FLAGS"
+.PP
+The second portion of a conversion specifier may contain any of the
+following flag characters, in any order:
+.TP 10
+\fB\-\fR
+Specifies that the converted argument should be left-justified 
+in its field (numbers are normally right-justified with leading 
+spaces if needed).
+.TP 10
+\fB+\fR
+Specifies that a number should always be printed with a sign, 
+even if positive.
+.TP 10
+\fIspace\fR
+Specifies that a space should be added to the beginning of the
+number if the first character is not a sign.
+.TP 10
+\fB0\fR
+Specifies that the number should be padded on the left with 
+zeroes instead of spaces.
+.TP 10
+\fB#\fR
+Requests an alternate output form. For \fBo\fR and \fBO\fR
+conversions it guarantees that the first digit is always \fB0\fR.
+For \fBx\fR or \fBX\fR conversions, \fB0x\fR or \fB0X\fR (respectively)
+will be added to the beginning of the result unless it is zero.
+For \fBb\fR conversions, \fB0b\fR
+will be added to the beginning of the result unless it is zero.
+For all floating-point conversions (\fBe\fR, \fBE\fR, \fBf\fR,
+\fBg\fR, and \fBG\fR) it guarantees that the result always 
+has a decimal point.
+For \fBg\fR and \fBG\fR conversions it specifies that 
+trailing zeroes should not be removed.
+.SS "OPTIONAL FIELD WIDTH"
+.PP
+The third portion of a conversion specifier is a decimal number giving a
+minimum field width for this conversion.
+It is typically used to make columns line up in tabular printouts.
+If the converted argument contains fewer characters than the
+minimum field width then it will be padded so that it is as wide
+as the minimum field width.
+Padding normally occurs by adding extra spaces on the left of the
+converted argument, but the \fB0\fR and \fB\-\fR flags 
+may be used to specify padding with zeroes on the left or with
+spaces on the right, respectively.
+If the minimum field width is specified as \fB*\fR rather than
+a number, then the next argument to the \fBformat\fR command
+determines the minimum field width; it must be an integer value.
+.SS "OPTIONAL PRECISION/BOUND"
+.PP
+The fourth portion of a conversion specifier is a precision,
+which consists of a period followed by a number.
+The number is used in different ways for different conversions.
+For \fBe\fR, \fBE\fR, and \fBf\fR conversions it specifies the number
+of digits to appear to the right of the decimal point.
+For \fBg\fR and \fBG\fR conversions it specifies the total number
+of digits to appear, including those on both sides of the decimal
+point (however, trailing zeroes after the decimal point will still
+be omitted unless the \fB#\fR flag has been specified).
+For integer conversions, it specifies a minimum number of digits
+to print (leading zeroes will be added if necessary).
+For \fBs\fR conversions it specifies the maximum number of characters to be 
+printed; if the string is longer than this then the trailing characters will be dropped.
+If the precision is specified with \fB*\fR rather than a number
+then the next argument to the \fBformat\fR command determines the precision;
+it must be a numeric string.
+.SS "OPTIONAL SIZE MODIFIER"
+.PP
+The fifth part of a conversion specifier is a size modifier,
+which must be \fBll\fR, \fBh\fR, or \fBl\fR.
+If it is \fBll\fR it specifies that an integer value is taken
+without truncation for conversion to a formatted substring.
+If it is \fBh\fR it specifies that an integer value is
+truncated to a 16-bit range before converting.  This option is rarely useful.
+If it is \fBl\fR it specifies that the integer value is 
+truncated to the same range as that produced by the \fBwide()\fR
+function of the \fBexpr\fR command (at least a 64-bit range).
+If neither \fBh\fR nor \fBl\fR are present, the integer value is
+truncated to the same range as that produced by the \fBint()\fR
+function of the \fBexpr\fR command (at least a 32-bit range, but
+determined by the value of the \fBwordSize\fR element of the
+\fBtcl_platform\fR array).
+.SS "MANDATORY CONVERSION TYPE"
+.PP
+The last thing in a conversion specifier is an alphabetic character
+that determines what kind of conversion to perform.
+The following conversion characters are currently supported:
+.TP 10
+\fBd\fR
+Convert integer to signed decimal string.
+.TP 10
+\fBu\fR
+Convert integer to unsigned decimal string.
+.TP 10
+\fBi\fR
+Convert integer to signed decimal string (equivalent to \fBd\fR).
+.TP 10
+\fBo\fR
+Convert integer to unsigned octal string.
+.TP 10
+\fBx\fR or \fBX\fR
+Convert integer to unsigned hexadecimal string, using digits
+.QW 0123456789abcdef
+for \fBx\fR and
+.QW 0123456789ABCDEF
+for \fBX\fR).
+.TP 10
+\fBb\fR
+Convert integer to binary string, using digits 0 and 1.
+.TP 10
+\fBc\fR
+Convert integer to the Unicode character it represents.
+.TP 10
+\fBs\fR
+No conversion; just insert string.
+.TP 10
+\fBf\fR
+Convert number to signed decimal string of 
+the form \fIxx.yyy\fR, where the number of \fIy\fR's is determined by 
+the precision (default: 6).
+If the precision is 0 then no decimal point is output.
+.TP 10
+\fBe\fR or \fBE\fR
+Convert number to scientific notation in the 
+form \fIx.yyy\fBe\(+-\fIzz\fR, where the number of \fIy\fR's is determined 
+by the precision (default: 6).
+If the precision is 0 then no decimal point is output.
+If the \fBE\fR form is used then \fBE\fR is 
+printed instead of \fBe\fR.
+.TP 10
+\fBg\fR or \fBG\fR
+If the exponent is less than \-4 or greater than or equal to the 
+precision, then convert number as for \fB%e\fR or 
+\fB%E\fR.
+Otherwise convert as for \fB%f\fR.
+Trailing zeroes and a trailing decimal point are omitted.
+.TP 10
+\fB%\fR
+No conversion: just insert \fB%\fR.
+.SH "DIFFERENCES FROM ANSI SPRINTF"
+.PP
+The behavior of the format command is the same as the
+ANSI C \fBsprintf\fR procedure except for the following
+differences:
+.IP [1]
+Tcl guarantees that it will be working with UNICODE characters.
+.IP [2]
+\fB%p\fR and \fB%n\fR specifiers are not supported.
+.IP [3]
+For \fB%c\fR conversions the argument must be an integer value,
+which will then be converted to the corresponding character value.
+.IP [4]
+The size modifiers are ignored when formatting floating-point values.
+The \fBll\fR modifier has no \fBsprintf\fR counterpart.
+The \fBb\fR specifier has no \fBsprintf\fR counterpart.
+.SH EXAMPLES

+that name and the return value is a count of the number of characters
+returned.

+If end of file occurs while scanning for an end of
+line, the command returns whatever input is available up to the end of file.
+If \fIchannelId\fR is in non-blocking mode and there is not a full

+does not consume any input.
+If \fIvarName\fR is specified and an empty string is returned in
+\fIvarName\fR because of end-of-file or because of insufficient
+data in non-blocking mode, then the return count is -1.
+Note that if \fIvarName\fR is not specified then the end-of-file
+and no-full-line-available cases can
+produce the same results as if there were an input line consisting
+only of the end-of-line character(s).
+The \fBeof\fR and \fBfblocked\fR commands can be used to distinguish

+.SH NAME
+glob \- Return names of files that match patterns
+.SH SYNOPSIS
+\fBglob \fR?\fIswitches\fR? ?\fIpattern ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command performs file name
+.QW globbing
+in a fashion similar to
+the csh shell or bash shell.
+It returns a list of the files whose names match any
+of the \fIpattern\fR arguments. No particular order is guaranteed
+in the list, so if a sorted list is required the caller should use
+\fBlsort\fR.
+.SS OPTIONS
+.PP
+If the initial arguments to \fBglob\fR start with \fB\-\fR then
+they are treated as switches. The following switches are
+currently supported:
+.TP
+\fB\-directory\fR \fIdirectory\fR
+.
+Search for files which match the given patterns starting in the given
+\fIdirectory\fR. This allows searching of directories whose name
+contains glob-sensitive characters without the need to quote such
+characters explicitly. This option may not be used in conjunction with
+\fB\-path\fR, which is used to allow searching for complete file paths
+whose names may contain glob-sensitive characters.
+.TP
+\fB\-join\fR
+.
+The remaining pattern arguments, after option processing, are treated
+as a single pattern obtained by joining the arguments with directory
+separators.
+.TP
+\fB\-nocomplain\fR
+.
+Allows an empty list to be returned without error; without this
+switch an error is returned if the result list would be empty.
+.TP
+\fB\-path\fR \fIpathPrefix\fR
+.
+Search for files with the given \fIpathPrefix\fR where the rest of the name
+matches the given patterns. This allows searching for files with names
+similar to a given file (as opposed to a directory) even when the names
+contain glob-sensitive
+characters. This option may not be used in conjunction with
+\fB\-directory\fR. For example, to find all files with the same root name
+as $path, but differing extensions, you should use
+.QW "\fBglob \-path [file rootname $path] .*\fR"
+which will work even if \fB$path\fR contains
+numerous glob-sensitive characters.
+.TP
+\fB\-tails\fR
+.
+Only return the part of each file found which follows the last directory
+named in any \fB\-directory\fR or \fB\-path\fR path specification.
+Thus
+.QW "\fBglob \-tails \-directory $dir *\fR"
+is equivalent to
+.QW "\fBset pwd [pwd]; cd $dir; glob *; cd $pwd\fR" .
+For \fB\-path\fR specifications, the returned names will include the last
+path segment, so
+.QW "\fBglob \-tails \-path [file rootname ~/foo.tex] .*\fR"
+will return paths like \fBfoo.aux foo.bib foo.tex\fR etc.
+.TP
+\fB\-types\fR \fItypeList\fR
+.
+Only list files or directories which match \fItypeList\fR, where the items
+in the list have two forms. The first form is like the \-type option of
+the Unix find command:
+\fIb\fR (block special file),
+\fIc\fR (character special file),
+\fId\fR (directory),
+\fIf\fR (plain file),
+\fIl\fR (symbolic link),
+\fIp\fR (named pipe),
+or \fIs\fR (socket), where multiple types may be specified in the list.
+\fBGlob\fR will return all files which match at least one of the types given.
+Note that symbolic links will be returned both if \fB\-types l\fR is given,
+or if the target of a link matches the requested type. So, a link to
+a directory will be returned if \fB\-types d\fR was specified.
+.RS
+.PP
+The second form specifies types where all the types given must match.
+These are \fIr\fR, \fIw\fR, \fIx\fR as file permissions, and
+\fIreadonly\fR, \fIhidden\fR as special permission cases. On the
+Macintosh, MacOS types and creators are also supported, where any item
+which is four characters long is assumed to be a MacOS type
+(e.g. \fBTEXT\fR). Items which are of the form \fI{macintosh type XXXX}\fR
+or \fI{macintosh creator XXXX}\fR will match types or creators
+respectively. Unrecognized types, or specifications of multiple MacOS
+types/creators will signal an error.
+.PP
+The two forms may be mixed, so \fB\-types {d f r w}\fR will find all
+regular files OR directories that have both read AND write permissions.
+The following are equivalent:
+.PP
+.CS
+\fBglob \-type d *\fR
+\fBglob */\fR
+.CE
+.PP
+except that the first case doesn't return the trailing
+.QW /
+and is more platform independent.
+.RE
+.TP
+\fB\-\|\-\fR
+.
+Marks the end of switches. The argument following this one will
+be treated as a \fIpattern\fR even if it starts with a \fB\-\fR.
+.SS "GLOBBING PATTERNS"
+.PP
+The \fIpattern\fR arguments may contain any of the following
+special characters, which are a superset of those supported by
+\fBstring match\fR:
+.TP 10
+\fB?\fR
+.
+Matches any single character.
+.TP 10
+\fB*\fR
+.
+Matches any sequence of zero or more characters.
+.TP 10
+\fB[\fIchars\fB]\fR
+.
+Matches any single character in \fIchars\fR. If \fIchars\fR
+contains a sequence of the form \fIa\fB\-\fIb\fR then any
+character between \fIa\fR and \fIb\fR (inclusive) will match.
+.TP 10
+\fB\e\fIx\fR
+.
+Matches the character \fIx\fR.
+.TP 10
+\fB{\fIa\fB,\fIb\fB,\fI...\fR}
+.
+Matches any of the sub-patterns \fIa\fR, \fIb\fR, etc.
+.PP
+On Unix, as with csh, a
+.QW . \|
+at the beginning of a file's name or just after a
+.QW /
+must be matched explicitly or with a {} construct, unless the
+\fB\-types hidden\fR flag is given (since
+.QW . \|
+at the beginning of a file's name indicates that it is hidden). On
+other platforms, files beginning with a
+.QW . \|
+are handled no differently to any others, except the special directories
+.QW . \|
+and
+.QW .. \|
+which must be matched explicitly (this is to avoid a recursive pattern like
+.QW "glob \-join * * * *"
+from recursing up the directory hierarchy as well as down). In addition, all
+.QW /
+characters must be matched explicitly.
+.LP
+If the first character in a \fIpattern\fR is
+.QW ~
+then it refers to the home directory for the user whose name follows the
+.QW ~ .
+If the
+.QW ~
+is followed immediately by
+.QW /
+then the value of the HOME environment variable is used.
+.PP
+The \fBglob\fR command differs from csh globbing in two ways.
+First, it does not sort its result list (use the \fBlsort\fR
+command if you want the list sorted).
+Second, \fBglob\fR only returns the names of files that actually
+exist; in csh no check for existence is made unless a pattern
+contains a ?, *, or [] construct.
+.LP
+When the \fBglob\fR command returns relative paths whose filenames
+start with a tilde
+.QW ~
+(for example through \fBglob *\fR or \fBglob \-tails\fR, the returned
+list will not quote the tilde with
+.QW ./ .
+This means care must be taken if those names are later to
+be used with \fBfile join\fR, to avoid them being interpreted as
+absolute paths pointing to a given user's home directory.
+.SH "WINDOWS PORTABILITY ISSUES"
+.PP
+For Windows UNC names, the servername and sharename components of the path
+may not contain ?, *, or [] constructs. On Windows NT, if \fIpattern\fR is
+of the form
+.QW \fB~\fIusername\fB@\fIdomain\fR ,
+it refers to the home
+directory of the user whose account information resides on the specified NT
+domain server. Otherwise, user account information is obtained from
+the local computer. On Windows 95 and 98, \fBglob\fR accepted patterns
+like
+.QW .../
+and
+.QW ..../
+for successively higher up parent directories, but later versions of
+Windows do not accept these forms.
+.PP
+Since the backslash character has a special meaning to the glob
+command, glob patterns containing Windows style path separators need
+special care. The pattern
+.QW \fIC:\e\efoo\e\e*\fR
+is interpreted as
+.QW \fIC:\efoo\e*\fR
+where
+.QW \fI\ef\fR
+will match the single character
+.QW \fIf\fR
+and
+.QW \fI\e*\fR
+will match the single character
+.QW \fI*\fR
+and will not be
+interpreted as a wildcard character. One solution to this problem is
+to use the Unix style forward slash as a path separator. Windows style
+paths can be converted to Unix style paths with the command
+.QW "\fBfile join\fR \fB$path\fR"
+or
+.QW "\fBfile normalize\fR \fB$path\fR" .

+.SH NAME
+history \- Manipulate the history list
+.SH SYNOPSIS
+\fBhistory \fR?\fIoption\fR? ?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+The \fBhistory\fR command performs one of several operations related to
+recently-executed commands recorded in a history list.  Each of
+these recorded commands is referred to as an
+.QW event .
+When specifying an event to the \fBhistory\fR command, the following
+forms may be used:
+.IP [1]
+A number:  if positive, it refers to the event with
+that number (all events are numbered starting at 1).  If the number
+is negative, it selects an event relative to the current event
+(\fB\-1\fR refers to the previous event, \fB\-2\fR to the one before that, and
+so on).  Event \fB0\fR refers to the current event.
+.IP [2]
+A string:  selects the most recent event that matches the string.
+An event is considered to match the string either if the string is
+the same as the first characters of the event, or if the string
+matches the event in the sense of the \fBstring match\fR command.
+.PP
+The \fBhistory\fR command can take any of the following forms:
+.TP
+\fBhistory\fR
+Same
+as \fBhistory info\fR, described below.
+.TP
+\fBhistory add\fI command \fR?\fBexec\fR?
+Adds the \fIcommand\fR argument to the history list as a new event.  If
+\fBexec\fR is specified (or abbreviated) then the command is also
+executed and its result is returned.  If \fBexec\fR is not specified
+then an empty string is returned as result.
+.TP
+\fBhistory change\fI newValue\fR ?\fIevent\fR?
+Replaces the value recorded for an event with \fInewValue\fR.  \fIEvent\fR
+specifies the event to replace, and
+defaults to the \fIcurrent\fR event (not event \fB\-1\fR).  This command
+is intended for use in commands that implement new forms of history
+substitution and wish to replace the current event (which invokes the
+substitution) with the command created through substitution.  The return
+value is an empty string.
+.TP
+\fBhistory clear\fR
+Erase the history list.  The current keep limit is retained.
+The history event numbers are reset.
+.TP
+\fBhistory event\fR ?\fIevent\fR?
+Returns the value of the event given by \fIevent\fR.  \fIEvent\fR
+defaults to \fB\-1\fR.
+.TP
+\fBhistory info \fR?\fIcount\fR?
+Returns a formatted string (intended for humans to read) giving
+the event number and contents for each of the events in the history
+list except the current event.  If \fIcount\fR is specified
+then only the most recent \fIcount\fR events are returned.
+.TP
+\fBhistory keep \fR?\fIcount\fR?
+This command may be used to change the size of the history list to
+\fIcount\fR events.  Initially, 20 events are retained in the history
+list.  If \fIcount\fR is not specified, the current keep limit is returned.
+.TP
+\fBhistory nextid\fR
+Returns the number of the next event to be recorded
+in the history list.  It is useful for things like printing the
+event number in command-line prompts.
+.TP
+\fBhistory redo \fR?\fIevent\fR?
+Re-executes the command indicated by \fIevent\fR and returns its result.
+\fIEvent\fR defaults to \fB\-1\fR.  This command results in history
+revision:  see below for details.
+.SH "HISTORY REVISION"
+.PP
+Pre-8.0 Tcl had a complex history revision mechanism.
+The current mechanism is more limited, and the old
+history operations \fBsubstitute\fR and \fBwords\fR have been removed.
+(As a consolation, the \fBclear\fR operation was added.)
+.PP
+The history option \fBredo\fR results in much simpler
+.QW "history revision" .
+When this option is invoked then the most recent event
+is modified to eliminate the history command and replace it with
+the result of the history command.
+If you want to redo an event without modifying history, then use
+the \fBevent\fR operation to retrieve some event,
+and the \fBadd\fR operation to add it to history and execute it.

+.SH DESCRIPTION
+.PP
+The \fBhttp\fR package provides the client side of the HTTP/1.1
+protocol, as defined in RFC 2616.
+The package implements the GET, POST, and HEAD operations
+of HTTP/1.1.  It allows configuration of a proxy host to get through
+firewalls.  The package is compatible with the \fBSafesock\fR security
+policy, so it can be used by untrusted applets to do URL fetching from
+a restricted set of hosts. This package can be extended to support
+additional HTTP transport protocols, such as HTTPS, by providing
+a custom \fBsocket\fR command, via \fB::http::register\fR.
+.PP
+The \fB::http::geturl\fR procedure does a HTTP transaction.
+Its \fIoptions \fR determine whether a GET, POST, or HEAD transaction
+is performed.  
+The return value of \fB::http::geturl\fR is a token for the transaction.
+The value is also the name of an array in the ::http namespace
+that contains state information about the transaction.  The elements
+of this array are described in the \fBSTATE ARRAY\fR section.
+.PP
+If the \fB\-command\fR option is specified, then
+the HTTP operation is done in the background.
+\fB::http::geturl\fR returns immediately after generating the
+HTTP request and the callback is invoked
+when the transaction completes.  For this to work, the Tcl event loop
+must be active.  In Tk applications this is always true.  For pure-Tcl
+applications, the caller can use \fB::http::wait\fR after calling
+\fB::http::geturl\fR to start the event loop.
+.SH COMMANDS
+.TP
+\fB::http::config\fR ?\fIoptions\fR?
+.
+The \fB::http::config\fR command is used to set and query the name of the
+proxy server and port, and the User-Agent name used in the HTTP
+requests.  If no options are specified, then the current configuration
+is returned.  If a single argument is specified, then it should be one
+of the flags described below.  In this case the current value of
+that setting is returned.  Otherwise, the options should be a set of
+flags and values that define the configuration:
+.RS
+.TP
+\fB\-accept\fR \fImimetypes\fR
+.
+The Accept header of the request.  The default is */*, which means that
+all types of documents are accepted.  Otherwise you can supply a 
+comma-separated list of mime type patterns that you are
+willing to receive.  For example,
+.QW "image/gif, image/jpeg, text/*" .
+.TP
+\fB\-proxyhost\fR \fIhostname\fR
+.
+The name of the proxy host, if any.  If this value is the
+empty string, the URL host is contacted directly.
+.TP
+\fB\-proxyport\fR \fInumber\fR
+.
+The proxy port number.
+.TP
+\fB\-proxyfilter\fR \fIcommand\fR
+.
+The command is a callback that is made during
+\fB::http::geturl\fR
+to determine if a proxy is required for a given host.  One argument, a
+host name, is added to \fIcommand\fR when it is invoked.  If a proxy
+is required, the callback should return a two-element list containing
+the proxy server and proxy port.  Otherwise the filter should return
+an empty list.  The default filter returns the values of the
+\fB\-proxyhost\fR and \fB\-proxyport\fR settings if they are
+non-empty.
+.TP
+\fB\-urlencoding\fR \fIencoding\fR
+.
+The \fIencoding\fR used for creating the x-url-encoded URLs with
+\fB::http::formatQuery\fR.  The default is \fButf-8\fR, as specified by RFC
+2718.  Prior to http 2.5 this was unspecified, and that behavior can be
+returned by specifying the empty string (\fB{}\fR), although
+\fIiso8859-1\fR is recommended to restore similar behavior but without the
+\fB::http::formatQuery\fR throwing an error processing non-latin-1
+characters.
+.TP
+\fB\-useragent\fR \fIstring\fR
+.
+The value of the User-Agent header in the HTTP request.  The default is
+.QW "\fBTcl http client package 2.7\fR" .
+.RE
+.TP
+\fB::http::geturl\fR \fIurl\fR ?\fIoptions\fR? 
+.
+The \fB::http::geturl\fR command is the main procedure in the package.
+The \fB\-query\fR option causes a POST operation and
+the \fB\-validate\fR option causes a HEAD operation;
+otherwise, a GET operation is performed.  The \fB::http::geturl\fR command
+returns a \fItoken\fR value that can be used to get
+information about the transaction.  See the \fBSTATE ARRAY\fR and
+\fBERRORS\fR section for
+details.  The \fB::http::geturl\fR command blocks until the operation
+completes, unless the \fB\-command\fR option specifies a callback
+that is invoked when the HTTP transaction completes.
+\fB::http::geturl\fR takes several options:
+.RS
+.TP
+\fB\-binary\fR \fIboolean\fR
+.
+Specifies whether to force interpreting the URL data as binary.  Normally
+this is auto-detected (anything not beginning with a \fBtext\fR content
+type or whose content encoding is \fBgzip\fR or \fBcompress\fR is
+considered binary data).
+.TP
+\fB\-blocksize\fR \fIsize\fR
+.
+The block size used when reading the URL.
+At most \fIsize\fR bytes are read at once.  After each block, a call to the
+\fB\-progress\fR callback is made (if that option is specified).
+.TP
+\fB\-channel\fR \fIname\fR
+.
+Copy the URL contents to channel \fIname\fR instead of saving it in
+\fBstate(body)\fR.
+.TP
+\fB\-command\fR \fIcallback\fR
+.
+Invoke \fIcallback\fR after the HTTP transaction completes.
+This option causes \fB::http::geturl\fR to return immediately.
+The \fIcallback\fR gets an additional argument that is the \fItoken\fR returned
+from \fB::http::geturl\fR. This token is the name of an array that is
+described in the \fBSTATE ARRAY\fR section.  Here is a template for the
+callback:
+.RS
+.PP
+.CS
+proc httpCallback {token} {
+    upvar #0 $token state
+    # Access state as a Tcl array
+}
+.CE
+.RE
+.TP
+\fB\-handler\fR \fIcallback\fR

+\fB\-headers\fR \fIkeyvaluelist\fR
+.
+This option is used to add extra headers to the HTTP request.  The
+\fIkeyvaluelist\fR argument must be a list with an even number of
+elements that alternate between keys and values.  The keys become
+header field names.  Newlines are stripped from the values so the
+header cannot be corrupted.  For example, if \fIkeyvaluelist\fR is
+\fBPragma no-cache\fR then the following header is included in the

+\fB\-keepalive\fR \fIboolean\fR
+.
+If true, attempt to keep the connection open for servicing
+multiple requests.  Default is 0.
+.TP
+\fB\-method\fR \fItype\fR
+.
+Force the HTTP request method to \fItype\fR. \fB::http::geturl\fR will
+auto-select GET, POST or HEAD based on other options, but this option
+enables choices like PUT and DELETE for webdav support.
+.TP
+\fB\-myaddr\fR \fIaddress\fR
+.
+Pass an specific local address to the underlying \fBsocket\fR call in case
+multiple interfaces are available.
+.TP
+\fB\-progress\fR \fIcallback\fR
+.
+The \fIcallback\fR is made after each transfer of data from the URL.
+The callback gets three additional arguments: the \fItoken\fR from
+\fB::http::geturl\fR, the expected total size of the contents from the
+\fBContent-Length\fR meta-data, and the current number of bytes
+transferred so far.  The expected total size may be unknown, in which
+case zero is passed to the callback.  Here is a template for the

+.TP
+\fB\-protocol\fR \fIversion\fR
+.
+Select the HTTP protocol version to use. This should be 1.0 or 1.1 (the
+default). Should only be necessary for servers that do not understand or
+otherwise complain about HTTP/1.1.
+.TP
+\fB\-query\fR \fIquery\fR
+.
+This flag causes \fB::http::geturl\fR to do a POST request that passes the
+\fIquery\fR to the server. The \fIquery\fR must be an x-url-encoding
+formatted query.  The \fB::http::formatQuery\fR procedure can be used to
+do the formatting.
+.TP
+\fB\-queryblocksize\fR \fIsize\fR
+.
+The block size used when posting query data to the URL.
+At most 
+\fIsize\fR
+bytes are written at once.  After each block, a call to the
+\fB\-queryprogress\fR
+callback is made (if that option is specified).
+.TP
+\fB\-querychannel\fR \fIchannelID\fR
+.
+This flag causes \fB::http::geturl\fR to do a POST request that passes the
+data contained in \fIchannelID\fR to the server. The data contained in
+\fIchannelID\fR must be an x-url-encoding
+formatted query unless the \fB\-type\fR option below is used.
+If a Content-Length header is not specified via the \fB\-headers\fR options,
+\fB::http::geturl\fR attempts to determine the size of the post data
+in order to create that header.  If it is
+unable to determine the size, it returns an error.
+.TP
+\fB\-queryprogress\fR \fIcallback\fR
+.
+The \fIcallback\fR is made after each transfer of data to the URL
+(i.e. POST) and acts exactly like the \fB\-progress\fR option (the
+callback format is the same).
+.TP
+\fB\-strict\fR \fIboolean\fR
+.
+Whether to enforce RFC 3986 URL validation on the request.  Default is 1.
+.TP
+\fB\-timeout\fR \fImilliseconds\fR
+.
+If \fImilliseconds\fR is non-zero, then \fB::http::geturl\fR sets up a timeout
+to occur after the specified number of milliseconds.
+A timeout results in a call to \fB::http::reset\fR and to
+the \fB\-command\fR callback, if specified.
+The return value of \fB::http::status\fR is \fBtimeout\fR
+after a timeout has occurred.
+.TP
+\fB\-type\fR \fImime-type\fR
+.
+Use \fImime-type\fR as the \fBContent-Type\fR value, instead of the
+default value (\fBapplication/x-www-form-urlencoded\fR) during a
+POST operation.
+.TP
+\fB\-validate\fR \fIboolean\fR
+.
+If \fIboolean\fR is non-zero, then \fB::http::geturl\fR does an HTTP HEAD
+request.  This request returns meta information about the URL, but the
+contents are not returned.  The meta information is available in the
+\fBstate(meta) \fR variable after the transaction.  See the
+\fBSTATE ARRAY\fR section for details.
+.RE
+.TP
+\fB::http::formatQuery\fR \fIkey value\fR ?\fIkey value\fR ...?
+.
+This procedure does x-url-encoding of query data.  It takes an even
+number of arguments that are the keys and values of the query.  It
+encodes the keys and values, and generates one string that has the
+proper & and = separators.  The result is suitable for the
+\fB\-query\fR value passed to \fB::http::geturl\fR.
+.TP
+\fB::http::reset\fR \fItoken\fR ?\fIwhy\fR?
+.
+This command resets the HTTP transaction identified by \fItoken\fR, if any.
+This sets the \fBstate(status)\fR value to \fIwhy\fR, which defaults to
+\fBreset\fR, and then calls the registered \fB\-command\fR callback.
+.TP
+\fB::http::wait\fR \fItoken\fR
+.
+This is a convenience procedure that blocks and waits for the
+transaction to complete.  This only works in trusted code because it
+uses \fBvwait\fR.  Also, it is not useful for the case where
+\fB::http::geturl\fR is called \fIwithout\fR the \fB\-command\fR option
+because in this case the \fB::http::geturl\fR call does not return
+until the HTTP transaction is complete, and thus there is nothing to
+wait for.
+.TP
+\fB::http::data\fR \fItoken\fR
+.
+This is a convenience procedure that returns the \fBbody\fR element
+(i.e., the URL data) of the state array.
+.TP
+\fB::http::error\fR \fItoken\fR
+.
+This is a convenience procedure that returns the \fBerror\fR element
+of the state array.
+.TP
+\fB::http::status\fR \fItoken\fR
+.
+This is a convenience procedure that returns the \fBstatus\fR element of
+the state array.
+.TP
+\fB::http::code\fR \fItoken\fR
+.
+This is a convenience procedure that returns the \fBhttp\fR element of the
+state array.
+.TP
+\fB::http::ncode\fR \fItoken\fR
+.
+This is a convenience procedure that returns just the numeric return
+code (200, 404, etc.) from the \fBhttp\fR element of the state array.
+.TP
+\fB::http::size\fR \fItoken\fR
+.
+This is a convenience procedure that returns the \fBcurrentsize\fR
+element of the state array, which represents the number of bytes
+received from the URL in the \fB::http::geturl\fR call.
+.TP
+\fB::http::meta\fR \fItoken\fR
+.
+This is a convenience procedure that returns the \fBmeta\fR
+element of the state array which contains the HTTP response
+headers. See below for an explanation of this element.
+.TP
+\fB::http::cleanup\fR \fItoken\fR
+.
+This procedure cleans up the state associated with the connection
+identified by \fItoken\fR.  After this call, the procedures
+like \fB::http::data\fR cannot be used to get information
+about the operation.  It is \fIstrongly\fR recommended that you call
+this function after you are done with a given HTTP request.  Not doing
+so will result in memory not being freed, and if your app calls
+\fB::http::geturl\fR enough times, the memory leak could cause a
+performance hit...or worse.
+.TP
+\fB::http::register\fR \fIproto port command\fR
+.
+This procedure allows one to provide custom HTTP transport types
+such as HTTPS, by registering a prefix, the default port, and the
+command to execute to create the Tcl \fBchannel\fR. E.g.:
+.RS
+.PP
+.CS
+package require http
+package require tls
+
+::http::register https 443 ::tls::socket
+
+set token [::http::geturl https://my.secure.site/]
+.CE
+.RE
+.TP
+\fB::http::unregister\fR \fIproto\fR
+.
+This procedure unregisters a protocol handler that was previously
+registered via \fB::http::register\fR.
+.SH ERRORS
+The \fB::http::geturl\fR procedure will raise errors in the following cases:
+invalid command line options,
+an invalid URL,
+a URL on a non-existent host,
+or a URL at a bad port on an existing host.
+These errors mean that it
+cannot even start the network transaction.
+It will also raise an error if it gets an I/O error while
+writing out the HTTP request header.
+For synchronous \fB::http::geturl\fR calls (where \fB\-command\fR is
+not specified), it will raise an error if it gets an I/O error while
+reading the HTTP reply headers or data.  Because \fB::http::geturl\fR
+does not return a token in these cases, it does all the required
+cleanup and there is no issue of your app having to call
+\fB::http::cleanup\fR.
+.PP
+For asynchronous \fB::http::geturl\fR calls, all of the above error
+situations apply, except that if there is any error while reading the
+HTTP reply headers or data, no exception is thrown.  This is because
+after writing the HTTP headers, \fB::http::geturl\fR returns, and the
+rest of the HTTP transaction occurs in the background.  The command
+callback can check if any error occurred during the read by calling
+\fB::http::status\fR to check the status and if its \fIerror\fR,
+calling \fB::http::error\fR to get the error message.
+.PP
+Alternatively, if the main program flow reaches a point where it needs
+to know the result of the asynchronous HTTP request, it can call
+\fB::http::wait\fR and then check status and error, just as the
+callback does.
+.PP
+In any case, you must still call
+\fB::http::cleanup\fR to delete the state array when you are done.
+.PP
+There are other possible results of the HTTP transaction
+determined by examining the status from \fB::http::status\fR.
+These are described below.
+.TP
+\fBok\fR
+.
+If the HTTP transaction completes entirely, then status will be \fBok\fR.
+However, you should still check the \fB::http::code\fR value to get
+the HTTP status.  The \fB::http::ncode\fR procedure provides just
+the numeric error (e.g., 200, 404 or 500) while the \fB::http::code\fR
+procedure returns a value like
+.QW "HTTP 404 File not found" .
+.TP
+\fBeof\fR
+.
+If the server closes the socket without replying, then no error
+is raised, but the status of the transaction will be \fBeof\fR.
+.TP
+\fBerror\fR
+.
+The error message will also be stored in the \fBerror\fR status
+array element, accessible via \fB::http::error\fR.
+.PP
+Another error possibility is that \fB::http::geturl\fR is unable to
+write all the post query data to the server before the server
+responds and closes the socket.
+The error message is saved in the \fBposterror\fR status array
+element and then  \fB::http::geturl\fR attempts to complete the
+transaction.
+If it can read the server's response
+it will end up with an \fBok\fR status, otherwise it will have
+an \fBeof\fR status.
+.SH "STATE ARRAY"
+The \fB::http::geturl\fR procedure returns a \fItoken\fR that can be used to
+get to the state of the HTTP transaction in the form of a Tcl array.
+Use this construct to create an easy-to-use array variable:
+.PP
+.CS
+upvar #0 $token state
+.CE
+.PP
+Once the data associated with the URL is no longer needed, the state
+array should be unset to free up storage.
+The \fB::http::cleanup\fR procedure is provided for that purpose.
+The following elements of
+the array are supported:
+.RS
+.TP
+\fBbody\fR
+.
+The contents of the URL.  This will be empty if the \fB\-channel\fR
+option has been specified.  This value is returned by the \fB::http::data\fR command.
+.TP
+\fBcharset\fR
+.
+The value of the charset attribute from the \fBContent-Type\fR meta-data
+value.  If none was specified, this defaults to the RFC standard
+\fBiso8859-1\fR, or the value of \fB$::http::defaultCharset\fR.  Incoming
+text data will be automatically converted from this charset to utf-8.
+.TP
+\fBcoding\fR
+.
+A copy of the \fBContent-Encoding\fR meta-data value.
+.TP
+\fBcurrentsize\fR
+.
+The current number of bytes fetched from the URL.
+This value is returned by the \fB::http::size\fR command.
+.TP
+\fBerror\fR
+.
+If defined, this is the error string seen when the HTTP transaction
+was aborted.
+.TP
+\fBhttp\fR
+.
+The HTTP status reply from the server.  This value
+is returned by the \fB::http::code\fR command.  The format of this value is:
+.RS
+.PP
+.CS
+\fIHTTP/1.1 code string\fR
+.CE
+.PP
+The \fIcode\fR is a three-digit number defined in the HTTP standard.
+A code of 200 is OK.  Codes beginning with 4 or 5 indicate errors.
+Codes beginning with 3 are redirection errors.  In this case the
+\fBLocation\fR meta-data specifies a new URL that contains the
+requested information.
+.RE
+.TP
+\fBmeta\fR
+.
+The HTTP protocol returns meta-data that describes the URL contents.
+The \fBmeta\fR element of the state array is a list of the keys and
+values of the meta-data.  This is in a format useful for initializing
+an array that just contains the meta-data:
+.RS
+.PP
+.CS
+array set meta $state(meta)
+.CE
+.PP
+Some of the meta-data keys are listed below, but the HTTP standard defines
+more, and servers are free to add their own.
+.TP
+\fBContent-Type\fR
+.
+The type of the URL contents.  Examples include \fBtext/html\fR,
+\fBimage/gif,\fR \fBapplication/postscript\fR and
+\fBapplication/x-tcl\fR.
+.TP
+\fBContent-Length\fR
+.
+The advertised size of the contents.  The actual size obtained by
+\fB::http::geturl\fR is available as \fBstate(currentsize)\fR.
+.TP
+\fBLocation\fR
+.
+An alternate URL that contains the requested data.
+.RE
+.TP
+\fBposterror\fR
+.
+The error, if any, that occurred while writing
+the post query data to the server.
+.TP
+\fBstatus\fR
+.
+Either \fBok\fR, for successful completion, \fBreset\fR for
+user-reset, \fBtimeout\fR if a timeout occurred before the transaction
+could complete, or \fBerror\fR for an error condition.  During the
+transaction this value is the empty string.
+.TP
+\fBtotalsize\fR
+.
+A copy of the \fBContent-Length\fR meta-data value.
+.TP
+\fBtype\fR
+.
+A copy of the \fBContent-Type\fR meta-data value.
+.TP
+\fBurl\fR
+.
+The requested URL.
+.RE
+.SH EXAMPLE
+.PP
+This example creates a procedure to copy a URL to a file while printing a

+.BE
+
+.SH DESCRIPTION
+.PP
+The \fIif\fR command evaluates \fIexpr1\fR as an expression (in the
+same way that \fBexpr\fR evaluates its argument).  The value of the
+expression must be a boolean
+(a numeric value, where 0 is false and
+anything is true, or a string value such as \fBtrue\fR or \fByes\fR
+for true and \fBfalse\fR or \fBno\fR for false);
+if it is true then \fIbody1\fR is executed by passing it to the
+Tcl interpreter.
+Otherwise \fIexpr2\fR is evaluated as an expression and if it is true
+then \fBbody2\fR is executed, and so on.
+If none of the expressions evaluates to true then \fIbodyN\fR is
+executed.
+The \fBthen\fR and \fBelse\fR arguments are optional
+.QW "noise words"
+to make the command easier to read.
+There may be any number of \fBelseif\fR clauses, including zero.
+\fIBodyN\fR may also be omitted as long as \fBelse\fR is omitted too.
+The return value from the command is the result of the body script
+that was executed, or an empty string
+if none of the expressions was non-zero and there was no \fIbodyN\fR.
+.SH EXAMPLES
+.PP
+A simple conditional:

+.CE
+.PP
+Remember, expressions can be multi-line, but in that case it can be a

+.SH SYNOPSIS
+\fBinfo \fIoption \fR?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command provides information about various internals of the Tcl
+interpreter.
+The legal \fIoption\fRs (which may be abbreviated) are:
+.TP
+\fBinfo args \fIprocname\fR
+.
+Returns a list containing the names of the arguments to procedure
+\fIprocname\fR, in order.  \fIProcname\fR must be the name of a
+Tcl command procedure.
+.TP
+\fBinfo body \fIprocname\fR
+.
+Returns the body of procedure \fIprocname\fR.  \fIProcname\fR must be
+the name of a Tcl command procedure.
+.TP
+\fBinfo class\fI subcommand class\fR ?\fIarg ...\fR
+.VS 8.6
+Returns information about the class, \fIclass\fR. The \fIsubcommand\fRs are
+described in \fBCLASS INTROSPECTION\fR below.
+.VE 8.6
+.TP
+\fBinfo cmdcount\fR
+.
+Returns a count of the total number of commands that have been invoked
+in this interpreter.
+.TP
+\fBinfo commands \fR?\fIpattern\fR?
+.
+If \fIpattern\fR is not specified,
+returns a list of names of all the Tcl commands visible
+(i.e. executable without using a qualified name) to the current namespace,
+including both the built-in commands written in C and
+the command procedures defined using the \fBproc\fR command.
+If \fIpattern\fR is specified,
+only those names matching \fIpattern\fR are returned.
+Matching is determined using the same rules as for \fBstring match\fR.
+\fIpattern\fR can be a qualified name like \fBFoo::print*\fR.
+That is, it may specify a particular namespace
+using a sequence of namespace names separated by double colons (\fB::\fR),
+and may have pattern matching special characters
+at the end to specify a set of commands in that namespace.
+If \fIpattern\fR is a qualified name,
+the resulting list of command names has each one qualified with the name
+of the specified namespace, and only the commands defined in the named
+namespace are returned.
+.\" Technically, most of this hasn't changed; that's mostly just the

+This form is an even-sized list alternating tokens and parameters. Tokens are
+currently either \fBCALL\fR, \fBUP\fR, or \fBINNER\fR, but other values may be
+introduced in the future. \fBCALL\fR indicates a procedure call, and its
+parameter is the corresponding \fBinfo level\fR \fB0\fR. \fBUP\fR indicates a
+shift in variable frames generated by \fBuplevel\fR or similar, and applies to
+the previous \fBCALL\fR item. Its parameter is the level offset. \fBINNER\fR

+\fBinfo frame\fR ?\fInumber\fR?
+.
+This command provides access to all frames on the stack, even those
+hidden from \fBinfo level\fR. If \fInumber\fR is not specified, this
+command returns a number giving the frame level of the command. This
+is 1 if the command is invoked at top-level. If \fInumber\fR is
+specified, then the result is a dictionary containing the location
+information for the command at the \fInumber\fRed level on the stack.
+.RS

+If \fInumber\fR is positive (> 0) then it selects a particular stack
+level (1 refers to the outer-most active command, 2 to the command it
+called, and so on, up to the current frame level which refers to
+\fBinfo frame\fR itself); otherwise it gives a level relative to the
+current command (0 refers to the current command, i.e., \fBinfo
+frame\fR itself, -1 to its caller, and so on).
+.PP
+This is similar to how \fBinfo level\fR works, except that this
+subcommand reports all frames, like \fBsource\fRd scripts,
+\fBeval\fRs, \fBuplevel\fRs, etc.
+.PP
+Note that for nested commands, like
+.QW "foo [bar [x]]" ,
+only
+.QW x
+will be seen by an \fBinfo frame\fR invoked within
+.QW x .
+This is the same as for \fBinfo level\fR and error stack traces.
+.PP
+The result dictionary may contain the keys listed below, with the

+\fBeval\fR, and \fBprecompiled\fR.
+.RS
+.TP
+\fBsource\fR\0\0\0\0\0\0\0\0

+\fBprecompiled\fR\0\0\0\0\0\0\0\0
+.

+available.
+.RE
+.TP
+\fBline\fR
+.
+This entry provides the number of the line the command is at inside of
+the script it is a part of. This information is not present for type
+\fBprecompiled\fR. For type \fBsource\fR this information is counted
+relative to the beginning of the file, whereas for the last two types
+the line is counted relative to the start of the script.
+.TP
+\fBfile\fR
+.
+This entry is present only for type \fBsource\fR. It provides the
+normalized path of the file the command is in.
+.TP
+\fBcmd\fR
+.
+This entry provides the string representation of the command. This is
+usually the unsubstituted form, however for commands which are a
+canonically-constructed list (e.g., as produced by the \fBlist\fR command)
+executed by \fBeval\fR it is the substituted form as they have no other
+string representation. Care is taken that the canonicality property of
+the latter is not spoiled.
+.TP
+\fBproc\fR
+.
+This entry is present only if the command is found in the body of a
+regular Tcl procedure. It then provides the name of that procedure.
+.TP
+\fBlambda\fR
+.
+This entry is present only if the command is found in the body of an
+anonymous Tcl procedure, i.e. a lambda. It then provides the entire
+definition of the lambda in question.
+.TP
+\fBlevel\fR
+.
+This entry is present only if the queried frame has a corresponding
+frame returned by \fBinfo level\fR. It provides the index of this
+frame, relative to the current level (0 and negative numbers).
+.PP
+A thing of note is that for procedures statically defined in files the
+locations of commands in their bodies will be reported with type
+\fBsource\fR and absolute line numbers, and not as type
+\fBproc\fR. The same is true for procedures nested in statically
+defined procedures, and literal eval scripts in files or statically
+defined procedures.
+.PP
+In contrast, procedure definitions and \fBeval\fR within a dynamically
+\fBeval\fRuated environment count line numbers relative to the start of
+their script, even if they would be able to count relative to the
+start of the outer dynamic script. That type of number usually makes
+more sense.
+.PP
+A different way of describing this behaviour is that file based
+locations are tracked as deeply as possible, and where this is not
+possible the lines are counted based on the smallest possible
+\fBeval\fR or procedure body, as that scope is usually easier to find
+than any dynamic outer scope.
+.PP
+The syntactic form \fB{*}\fR is handled like \fBeval\fR. I.e. if it
+is given a literal list argument the system tracks the line number
+within the list words as well, and otherwise all line numbers are
+counted relative to the start of each word (smallest scope)

+is positive then it selects a particular stack level (1 refers
+to the top-most active procedure, 2 to the procedure it called, and

+.SH NAME
+interp \- Create and manipulate Tcl interpreters
+.SH SYNOPSIS
+\fBinterp \fIsubcommand \fR?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command makes it possible to create one or more new Tcl
+interpreters that co-exist with the creating interpreter in the
+same application.  The creating interpreter is called the \fImaster\fR
+and the new interpreter is called a \fIslave\fR.
+A master can create any number of slaves, and each slave can
+itself create additional slaves for which it is master, resulting
+in a hierarchy of interpreters.
+.PP
+Each interpreter is independent from the others: it has its own name
+space for commands, procedures, and global variables.
+A master interpreter may create connections between its slaves and
+itself using a mechanism called an \fIalias\fR.  An \fIalias\fR is
+a command in a slave interpreter which, when invoked, causes a
+command to be invoked in its master interpreter or in another slave
+interpreter.  The only other connections between interpreters are
+through environment variables (the \fBenv\fR variable), which are
+normally shared among all interpreters in the application,
+and by resource limit exceeded callbacks. Note that the
+name space for files (such as the names returned by the \fBopen\fR command)
+is no longer shared between interpreters. Explicit commands are provided to
+share files and to transfer references to open files from one interpreter
+to another.
+.PP
+The \fBinterp\fR command also provides support for \fIsafe\fR
+interpreters.  A safe interpreter is a slave whose functions have
+been greatly restricted, so that it is safe to execute untrusted
+scripts without fear of them damaging other interpreters or the
+application's environment. For example, all IO channel creation
+commands and subprocess creation commands are made inaccessible to safe
+interpreters.
+See \fBSAFE INTERPRETERS\fR below for more information on
+what features are present in a safe interpreter.
+The dangerous functionality is not removed from the safe interpreter;
+instead, it is \fIhidden\fR, so that only trusted interpreters can obtain
+access to it. For a detailed explanation of hidden commands, see
+\fBHIDDEN COMMANDS\fR, below.
+The alias mechanism can be used for protected communication (analogous to a
+kernel call) between a slave interpreter and its master.
+See \fBALIAS INVOCATION\fR, below, for more details
+on how the alias mechanism works.
+.PP
+A qualified interpreter name is a proper Tcl lists containing a subset of its
+ancestors in the interpreter hierarchy, terminated by the string naming the
+interpreter in its immediate master. Interpreter names are relative to the
+interpreter in which they are used. For example, if
+.QW \fBa\fR
+is a slave of the current interpreter and it has a slave
+.QW \fBa1\fR ,
+which in turn has a slave
+.QW \fBa11\fR ,
+the qualified name of
+.QW \fBa11\fR
+in
+.QW \fBa\fR
+is the list
+.QW "\fBa1 a11\fR" .
+.PP
+The \fBinterp\fR command, described below, accepts qualified interpreter
+names as arguments; the interpreter in which the command is being evaluated
+can always be referred to as \fB{}\fR (the empty list or string). Note that
+it is impossible to refer to a master (ancestor) interpreter by name in a
+slave interpreter except through aliases. Also, there is no global name by
+which one can refer to the first interpreter created in an application.
+Both restrictions are motivated by safety concerns.
+.SH "THE INTERP COMMAND"
+.PP
+The \fBinterp\fR command is used to create, delete, and manipulate
+slave interpreters, and to share or transfer
+channels between interpreters.  It can have any of several forms, depending
+on the \fIsubcommand\fR argument:
+.TP
+\fBinterp\fR \fBalias\fR \fIsrcPath\fR \fIsrcToken\fR
+.
+Returns a Tcl list whose elements are the \fItargetCmd\fR and
+\fIarg\fRs associated with the alias represented by \fIsrcToken\fR
+(this is the value returned when the alias was
+created; it is possible that the name of the source command in the
+slave is different from \fIsrcToken\fR).
+.TP
+\fBinterp\fR \fBalias\fR \fIsrcPath\fR \fIsrcToken\fR \fB{}\fR
+.
+Deletes the alias for \fIsrcToken\fR in the slave interpreter identified by
+\fIsrcPath\fR.
+\fIsrcToken\fR refers to the value returned when the alias
+was created;  if the source command has been renamed, the renamed
+command will be deleted.
+.TP
+\fBinterp\fR \fBalias\fR \fIsrcPath\fR \fIsrcCmd\fR \fItargetPath\fR \fItargetCmd \fR?\fIarg arg ...\fR?
+.
+This command creates an alias between one slave and another (see the
+\fBalias\fR slave command below for creating aliases between a slave
+and its master).  In this command, either of the slave interpreters
+may be anywhere in the hierarchy of interpreters under the interpreter
+invoking the command.
+\fISrcPath\fR and \fIsrcCmd\fR identify the source of the alias.
+\fISrcPath\fR is a Tcl list whose elements select a particular
+interpreter.  For example,
+.QW "\fBa b\fR"
+identifies an interpreter
+.QW \fBb\fR ,
+which is a slave of interpreter
+.QW \fBa\fR ,
+which is a slave of the invoking interpreter.  An empty list specifies
+the interpreter invoking the command.  \fIsrcCmd\fR gives the name of
+a new command, which will be created in the source interpreter.
+\fITargetPath\fR and \fItargetCmd\fR specify a target interpreter
+and command, and the \fIarg\fR arguments, if any, specify additional
+arguments to \fItargetCmd\fR which are prepended to any arguments specified
+in the invocation of \fIsrcCmd\fR.
+\fITargetCmd\fR may be undefined at the time of this call, or it may
+already exist; it is not created by this command.
+The alias arranges for the given target command to be invoked
+in the target interpreter whenever the given source command is
+invoked in the source interpreter.  See \fBALIAS INVOCATION\fR below for
+more details.
+The command returns a token that uniquely identifies the command created
+\fIsrcCmd\fR, even if the command is renamed afterwards. The token may but
+does not have to be equal to \fIsrcCmd\fR.
+.TP
+\fBinterp\fR \fBaliases \fR?\fIpath\fR?
+.
+This command returns a Tcl list of the tokens of all the source commands for
+aliases defined in the interpreter identified by \fIpath\fR. The tokens
+correspond to the values returned when
+the aliases were created (which may not be the same
+as the current names of the commands).
+.TP
+\fBinterp bgerror \fIpath\fR ?\fIcmdPrefix\fR?
+.
+This command either gets or sets the current background exception handler
+for the interpreter identified by \fIpath\fR. If \fIcmdPrefix\fR is
+absent, the current background exception handler is returned, and if it is
+present, it is a list of words (of minimum length one) that describes
+what to set the interpreter's background exception handler to. See the
+\fBBACKGROUND EXCEPTION HANDLING\fR section for more details.
+.TP
+\fBinterp\fR \fBcancel \fR?\fB\-unwind\fR? ?\fB\-\|\-\fR? ?\fIpath\fR? ?\fIresult\fR?
+.VS 8.6
+Cancels the script being evaluated in the interpreter identified by
+\fIpath\fR. Without the \fB\-unwind\fR switch the evaluation stack for
+the interpreter is unwound until an enclosing catch command is found or
+there are no further invocations of the interpreter left on the call
+stack. With the \fB\-unwind\fR switch the evaluation stack for the
+interpreter is unwound without regard to any intervening catch command
+until there are no further invocations of the interpreter left on the
+call stack. The \fB\-\|\-\fR switch can be used to mark the end of
+switches; it may be needed if \fIpath\fR is an unusual value such
+as \fB\-safe\fR. If \fIresult\fR is present, it will be used as the
+error message string; otherwise, a default error message string will be
+used.
+.VE 8.6
+.TP
+\fBinterp\fR \fBcreate \fR?\fB\-safe\fR? ?\fB\-\|\-\fR? ?\fIpath\fR?
+.
+Creates a slave interpreter identified by \fIpath\fR and a new command,
+called a \fIslave command\fR. The name of the slave command is the last
+component of \fIpath\fR. The new slave interpreter and the slave command
+are created in the interpreter identified by the path obtained by removing
+the last component from \fIpath\fR. For example, if \fIpath\fR is \fBa b
+c\fR then a new slave interpreter and slave command named \fBc\fR are
+created in the interpreter identified by the path \fBa b\fR.
+The slave command may be used to manipulate the new interpreter as
+described below. If \fIpath\fR is omitted, Tcl creates a unique name of the
+form \fBinterp\fIx\fR, where \fIx\fR is an integer, and uses it for the
+interpreter and the slave command. If the \fB\-safe\fR switch is specified
+(or if the master interpreter is a safe interpreter), the new slave
+interpreter will be created as a safe interpreter with limited
+functionality; otherwise the slave will include the full set of Tcl
+built-in commands and variables. The \fB\-\|\-\fR switch can be used to
+mark the end of switches;  it may be needed if \fIpath\fR is an unusual
+value such as \fB\-safe\fR. The result of the command is the name of the
+new interpreter. The name of a slave interpreter must be unique among all
+the slaves for its master;  an error occurs if a slave interpreter by the
+given name already exists in this master.
+The initial recursion limit of the slave interpreter is set to the
+current recursion limit of its parent interpreter.
+.TP
+\fBinterp\fR \fBdebug \fIpath\fR ?\fB\-frame\fR ?\fIbool\fR??
+.
+Controls whether frame-level stack information is captured in the
+slave interpreter identified by \fIpath\fR.  If no arguments are
+given, option and current setting are returned.  If \fB\-frame\fR
+is given, the debug setting is set to the given boolean if provided
+and the current setting is returned.
+This only effects the output of \fBinfo frame\fR, in that exact
+frame-level information for command invocation at the bytecode level
+is only captured with this setting on.
+.RS
+.PP
+For example, with code like
+.PP
+.CS
+\fBproc\fR mycontrol {... script} {
+  ...
+  \fBuplevel\fR 1 $script
+  ...
+}
+
+\fBproc\fR dosomething {...} {
+  ...
+  mycontrol {
+    somecode
+  }
+}
+.CE
+.PP
+the standard setting will provide a relative line number for the
+command \fBsomecode\fR and the relevant frame will be of type
+\fBeval\fR. With frame-debug active on the other hand the tracking
+extends so far that the system will be able to determine the file and
+absolute line number of this command, and return a frame of type
+\fBsource\fR. This more exact information is paid for with slower
+execution of all commands.
+.PP
+Note that once it is on, this flag cannot be switched back off: such
+attempts are silently ignored. This is needed to maintain the
+consistency of the underlying interpreter's state.
+.RE
+.TP
+\fBinterp\fR \fBdelete \fR?\fIpath ...?\fR
+.
+Deletes zero or more interpreters given by the optional \fIpath\fR
+arguments, and for each interpreter, it also deletes its slaves. The
+command also deletes the slave command for each interpreter deleted.
+For each \fIpath\fR argument, if no interpreter by that name
+exists, the command raises an error.
+.TP
+\fBinterp\fR \fBeval\fR \fIpath arg \fR?\fIarg ...\fR?
+.
+This command concatenates all of the \fIarg\fR arguments in the same
+fashion as the \fBconcat\fR command, then evaluates the resulting string as
+a Tcl script in the slave interpreter identified by \fIpath\fR. The result
+of this evaluation (including all \fBreturn\fR options,
+such as \fB\-errorinfo\fR and \fB\-errorcode\fR information, if an
+error occurs) is returned to the invoking interpreter.
+Note that the script will be executed in the current context stack frame of the
+\fIpath\fR interpreter; this is so that the implementations (in a master
+interpreter) of aliases in a slave interpreter can execute scripts in
+the slave that find out information about the slave's current state
+and stack frame.
+.TP
+\fBinterp exists \fIpath\fR
+.
+Returns \fB1\fR if a slave interpreter by the specified \fIpath\fR
+exists in this master, \fB0\fR otherwise. If \fIpath\fR is omitted, the
+invoking interpreter is used.
+.TP
+\fBinterp expose \fIpath\fR \fIhiddenName\fR ?\fIexposedCmdName\fR?
+.
+Makes the hidden command \fIhiddenName\fR exposed, eventually bringing
+it back under a new \fIexposedCmdName\fR name (this name is currently
+accepted only if it is a valid global name space name without any ::),
+in the interpreter
+denoted by \fIpath\fR.
+If an exposed command with the targeted name already exists, this command
+fails.
+Hidden commands are explained in more detail in \fBHIDDEN COMMANDS\fR, below.
+.TP
+\fBinterp\fR \fBhide\fR \fIpath\fR \fIexposedCmdName\fR ?\fIhiddenCmdName\fR?
+.
+Makes the exposed command \fIexposedCmdName\fR hidden, renaming
+it to the hidden command \fIhiddenCmdName\fR, or keeping the same name if
+\fIhiddenCmdName\fR is not given, in the interpreter denoted
+by \fIpath\fR.
+If a hidden command with the targeted name already exists, this command
+fails.
+Currently both \fIexposedCmdName\fR and \fIhiddenCmdName\fR can
+not contain namespace qualifiers, or an error is raised.
+Commands to be hidden by \fBinterp hide\fR are looked up in the global
+namespace even if the current namespace is not the global one. This
+prevents slaves from fooling a master interpreter into hiding the wrong
+command, by making the current namespace be different from the global one.
+Hidden commands are explained in more detail in \fBHIDDEN COMMANDS\fR, below.
+.TP
+\fBinterp\fR \fBhidden\fR \fIpath\fR
+.
+Returns a list of the names of all hidden commands in the interpreter
+identified by \fIpath\fR.
+.TP
+\fBinterp\fR \fBinvokehidden\fR \fIpath\fR ?\fI\-option ...\fR? \fIhiddenCmdName\fR ?\fIarg ...\fR?
+.
+Invokes the hidden command \fIhiddenCmdName\fR with the arguments supplied
+in the interpreter denoted by \fIpath\fR. No substitutions or evaluation
+are applied to the arguments. Three \fI\-option\fRs are supported, all
+of which start with \fB\-\fR: \fB\-namespace\fR (which takes a single
+argument afterwards, \fInsName\fR), \fB\-global\fR, and \fB\-\|\-\fR.
+If the \fB\-namespace\fR flag is present, the hidden command is invoked in
+the namespace called \fInsName\fR in the target interpreter.
+If the \fB\-global\fR flag is present, the hidden command is invoked at the
+global level in the target interpreter; otherwise it is invoked at the
+current call frame and can access local variables in that and outer call
+frames.
+The \fB\-\|\-\fR flag allows the \fIhiddenCmdName\fR argument to start with a
+.QW \-
+character, and is otherwise unnecessary.
+If both the \fB\-namespace\fR and \fB\-global\fR flags are present, the
+\fB\-namespace\fR flag is ignored.
+Note that the hidden command will be executed (by default) in the
+current context stack frame of the \fIpath\fR interpreter.
+Hidden commands are explained in more detail in \fBHIDDEN COMMANDS\fR, below.
+.TP
+\fBinterp issafe\fR ?\fIpath\fR?
+.
+Returns \fB1\fR if the interpreter identified by the specified \fIpath\fR
+is safe, \fB0\fR otherwise.
+.TP
+\fBinterp\fR \fBlimit\fR \fIpath\fR \fIlimitType\fR ?\fI\-option\fR? ?\fIvalue\fR \fI...\fR?
+.
+Sets up, manipulates and queries the configuration of the resource
+limit \fIlimitType\fR for the interpreter denoted by \fIpath\fR.  If
+no \fI\-option\fR is specified, return the current configuration of the
+limit.  If \fI\-option\fR is the sole argument, return the value of that
+option.  Otherwise, a list of \fI\-option\fR/\fIvalue\fR argument pairs
+must supplied. See \fBRESOURCE LIMITS\fR below for a more detailed
+explanation of what limits and options are supported.
+.TP
+\fBinterp marktrusted\fR \fIpath\fR
+.
+Marks the interpreter identified by \fIpath\fR as trusted. Does
+not expose the hidden commands. This command can only be invoked from a
+trusted interpreter.
+The command has no effect if the interpreter identified by \fIpath\fR is
+already trusted.
+.TP
+\fBinterp\fR \fBrecursionlimit\fR \fIpath\fR ?\fInewlimit\fR?
+.
+Returns the maximum allowable nesting depth for the interpreter
+specified by \fIpath\fR.  If \fInewlimit\fR is specified,
+the interpreter recursion limit will be set so that nesting
+of more than \fInewlimit\fR calls to \fBTcl_Eval\fR
+and related procedures in that interpreter will return an error.
+The \fInewlimit\fR value is also returned.
+The \fInewlimit\fR value must be a positive integer between 1 and the
+maximum value of a non-long integer on the platform.
+.RS
+.PP
+The command sets the maximum size of the Tcl call stack only. It cannot
+by itself prevent stack overflows on the C stack being used by the
+application. If your machine has a limit on the size of the C stack, you
+may get stack overflows before reaching the limit set by the command. If
+this happens, see if there is a mechanism in your system for increasing
+the maximum size of the C stack.
+.RE
+.TP
+\fBinterp\fR \fBshare\fR \fIsrcPath channelId destPath\fR
+.
+Causes the IO channel identified by \fIchannelId\fR to become shared
+between the interpreter identified by \fIsrcPath\fR and the interpreter
+identified by \fIdestPath\fR. Both interpreters have the same permissions
+on the IO channel.
+Both interpreters must close it to close the underlying IO channel; IO
+channels accessible in an interpreter are automatically closed when an
+interpreter is destroyed.
+.TP
+\fBinterp\fR \fBslaves\fR ?\fIpath\fR?
+.
+Returns a Tcl list of the names of all the slave interpreters associated
+with the interpreter identified by \fIpath\fR. If \fIpath\fR is omitted,
+the invoking interpreter is used.
+.TP
+\fBinterp\fR \fBtarget\fR \fIpath alias\fR
+.
+Returns a Tcl list describing the target interpreter for an alias. The
+alias is specified with an interpreter path and source command name, just
+as in \fBinterp alias\fR above. The name of the target interpreter is
+returned as an interpreter path, relative to the invoking interpreter.
+If the target interpreter for the alias is the invoking interpreter then an
+empty list is returned. If the target interpreter for the alias is not the
+invoking interpreter or one of its descendants then an error is generated.
+The target command does not have to be defined at the time of this invocation.
+.TP
+\fBinterp\fR \fBtransfer\fR \fIsrcPath channelId destPath\fR
+.
+Causes the IO channel identified by \fIchannelId\fR to become available in
+the interpreter identified by \fIdestPath\fR and unavailable in the
+interpreter identified by \fIsrcPath\fR.
+.SH "SLAVE COMMAND"
+.PP
+For each slave interpreter created with the \fBinterp\fR command, a
+new Tcl command is created in the master interpreter with the same
+name as the new interpreter. This command may be used to invoke
+various operations on the interpreter.  It has the following
+general form:
+.PP
+.CS
+\fIslave command \fR?\fIarg arg ...\fR?
+.CE
+.PP
+\fISlave\fR is the name of the interpreter, and \fIcommand\fR
+and the \fIarg\fRs determine the exact behavior of the command.
+The valid forms of this command are:
+.TP
+\fIslave \fBaliases\fR
+.
+Returns a Tcl list whose elements are the tokens of all the
+aliases in \fIslave\fR.  The tokens correspond to the values returned when
+the aliases were created (which may not be the same
+as the current names of the commands).
+.TP
+\fIslave \fBalias \fIsrcToken\fR
+.
+Returns a Tcl list whose elements are the \fItargetCmd\fR and
+\fIarg\fRs associated with the alias represented by \fIsrcToken\fR
+(this is the value returned when the alias was
+created; it is possible that the actual source command in the
+slave is different from \fIsrcToken\fR).
+.TP
+\fIslave \fBalias \fIsrcToken \fB{}\fR
+.
+Deletes the alias for \fIsrcToken\fR in the slave interpreter.
+\fIsrcToken\fR refers to the value returned when the alias
+was created;  if the source command has been renamed, the renamed
+command will be deleted.
+.TP
+\fIslave \fBalias \fIsrcCmd targetCmd \fR?\fIarg ..\fR?
+.
+Creates an alias such that whenever \fIsrcCmd\fR is invoked
+in \fIslave\fR, \fItargetCmd\fR is invoked in the master.
+The \fIarg\fR arguments will be passed to \fItargetCmd\fR as additional
+arguments, prepended before any arguments passed in the invocation of
+\fIsrcCmd\fR.
+See \fBALIAS INVOCATION\fR below for details.
+The command returns a token that uniquely identifies the command created
+\fIsrcCmd\fR, even if the command is renamed afterwards. The token may but
+does not have to be equal to \fIsrcCmd\fR.
+.TP
+\fIslave \fBbgerror\fR ?\fIcmdPrefix\fR?
+.
+This command either gets or sets the current background exception handler
+for the \fIslave\fR interpreter. If \fIcmdPrefix\fR is
+absent, the current background exception handler is returned, and if it is
+present, it is a list of words (of minimum length one) that describes
+what to set the interpreter's background exception handler to. See the
+\fBBACKGROUND EXCEPTION HANDLING\fR section for more details.
+.TP
+\fIslave \fBeval \fIarg \fR?\fIarg ..\fR?
+.
+This command concatenates all of the \fIarg\fR arguments in
+the same fashion as the \fBconcat\fR command, then evaluates
+the resulting string as a Tcl script in \fIslave\fR.
+The result of this evaluation (including all \fBreturn\fR options,
+such as \fB\-errorinfo\fR and \fB\-errorcode\fR information, if an
+error occurs) is returned to the invoking interpreter.
+Note that the script will be executed in the current context stack frame
+of \fIslave\fR; this is so that the implementations (in a master
+interpreter) of aliases in a slave interpreter can execute scripts in
+the slave that find out information about the slave's current state
+and stack frame.
+.TP
+\fIslave \fBexpose \fIhiddenName \fR?\fIexposedCmdName\fR?

+applied to the arguments. Three \fI\-option\fRs are supported, all
+of which start with \fB\-\fR: \fB\-namespace\fR (which takes a single
+argument afterwards, \fInsName\fR), \fB\-global\fR, and \fB\-\|\-\fR.
+If the \fB\-namespace\fR flag is given, the hidden command is invoked in
+the specified namespace in the slave.
+If the \fB\-global\fR flag is given, the command is invoked at the global
+level in the slave; otherwise it is invoked at the current call frame and
+can access local variables in that or outer call frames.
+The \fB\-\|\-\fR flag allows the \fIhiddenCmdName\fR argument to start with a
+.QW \-
+character, and is otherwise unnecessary.
+If both the \fB\-namespace\fR and \fB\-global\fR flags are given, the
+\fB\-namespace\fR flag is ignored.
+Note that the hidden command will be executed (by default) in the
+current context stack frame of \fIslave\fR.
+For more details on hidden commands,
+see \fBHIDDEN COMMANDS\fR, below.
+.TP
+\fIslave \fBissafe\fR

+.TP
+\fIslave \fBlimit\fR \fIlimitType\fR ?\fI\-option\fR? ?\fIvalue\fR \fI...\fR?
+.
+Sets up, manipulates and queries the configuration of the resource
+limit \fIlimitType\fR for the slave interpreter.  If no \fI\-option\fR
+is specified, return the current configuration of the limit.  If
+\fI\-option\fR is the sole argument, return the value of that option.
+Otherwise, a list of \fI\-option\fR/\fIvalue\fR argument pairs must
+supplied. See \fBRESOURCE LIMITS\fR below for a more detailed explanation of
+what limits and options are supported.
+.TP
+\fIslave \fBmarktrusted\fR
+.
+Marks the slave interpreter as trusted. Can only be invoked by a

+commands in the slave interpreter. The command has no effect if the slave
+is already trusted.
+.TP
+\fIslave\fR \fBrecursionlimit\fR ?\fInewlimit\fR?
+.
+Returns the maximum allowable nesting depth for the \fIslave\fR interpreter.
+If \fInewlimit\fR is specified, the recursion limit in \fIslave\fR will be
+set so that nesting of more than \fInewlimit\fR calls to \fBTcl_Eval()\fR
+and related procedures in \fIslave\fR will return an error.
+The \fInewlimit\fR value is also returned.
+The \fInewlimit\fR value must be a positive integer between 1 and the
+maximum value of a non-long integer on the platform.
+.RS
+.PP
+The command sets the maximum size of the Tcl call stack only. It cannot
+by itself prevent stack overflows on the C stack being used by the
+application. If your machine has a limit on the size of the C stack, you
+may get stack overflows before reaching the limit set by the command. If
+this happens, see if there is a mechanism in your system for increasing
+the maximum size of the C stack.
+.RE
+.SH "SAFE INTERPRETERS"
+.PP
+A safe interpreter is one with restricted functionality, so that
+is safe to execute an arbitrary script from your worst enemy without
+fear of that script damaging the enclosing application or the rest
+of your computing environment.  In order to make an interpreter
+safe, certain commands and variables are removed from the interpreter.
+For example, commands to create files on disk are removed, and the
+\fBexec\fR command is removed, since it could be used to cause damage
+through subprocesses.
+Limited access to these facilities can be provided, by creating
+aliases to the master interpreter which check their arguments carefully
+and provide restricted access to a safe subset of facilities.
+For example, file creation might be allowed in a particular subdirectory
+and subprocess invocation might be allowed for a carefully selected and
+fixed set of programs.
+.PP
+A safe interpreter is created by specifying the \fB\-safe\fR switch
+to the \fBinterp create\fR command.  Furthermore, any slave created
+by a safe interpreter will also be safe.
+.PP
+A safe interpreter is created with exactly the following set of
+built-in commands:
+.DS

+\fBtcl_wordBreakAfter\fR	\fBtcl_wordBreakBefore\fR
+.DE
+can only be provided by explicit definition of an \fBunknown\fR command
+in the safe interpreter.  This will involve exposing the \fBsource\fR
+command.  This is most easily accomplished by creating the safe interpreter
+with Tcl's \fBSafe\-Tcl\fR mechanism.  \fBSafe\-Tcl\fR provides safe
+versions of \fBsource\fR, \fBload\fR, and other Tcl commands needed
+to support autoloading of commands and the loading of packages.
+.PP
+In addition, the \fBenv\fR variable is not present in a safe interpreter,
+so it cannot share environment variables with other interpreters. The
+\fBenv\fR variable poses a security risk, because users can store
+sensitive information in an environment variable. For example, the PGP
+manual recommends storing the PGP private key protection password in
+the environment variable \fIPGPPASS\fR. Making this variable available
+to untrusted code executing in a safe interpreter would incur a
+security risk.
+.PP
+If extensions are loaded into a safe interpreter, they may also restrict
+their own functionality to eliminate unsafe commands. For a discussion of
+management of extensions for safety see the manual entries for
+\fBSafe\-Tcl\fR and the \fBload\fR Tcl command.
+.PP
+A safe interpreter may not alter the recursion limit of any interpreter,
+including itself.
+.SH "ALIAS INVOCATION"
+.PP
+The alias mechanism has been carefully designed so that it can
+be used safely when an untrusted script is executing
+in a safe slave and the target of the alias is a trusted
+master.  The most important thing in guaranteeing safety is to
+ensure that information passed from the slave to the master is
+never evaluated or substituted in the master;  if this were to
+occur, it would enable an evil script in the slave to invoke
+arbitrary functions in the master, which would compromise security.
+.PP
+When the source for an alias is invoked in the slave interpreter, the
+usual Tcl substitutions are performed when parsing that command.
+These substitutions are carried out in the source interpreter just
+as they would be for any other command invoked in that interpreter.
+The command procedure for the source command takes its arguments
+and merges them with the \fItargetCmd\fR and \fIarg\fRs for the
+alias to create a new array of arguments.  If the words
+of \fIsrcCmd\fR were
+.QW "\fIsrcCmd arg1 arg2 ... argN\fR" ,
+the new set of words will be
+.QW "\fItargetCmd arg arg ... arg arg1 arg2 ... argN\fR" ,
+where \fItargetCmd\fR and \fIarg\fRs are the values supplied when the
+alias was created.  \fITargetCmd\fR is then used to locate a command
+procedure in the target interpreter, and that command procedure
+is invoked with the new set of arguments.  An error occurs if
+there is no command named \fItargetCmd\fR in the target interpreter.
+No additional substitutions are performed on the words:  the
+target command procedure is invoked directly, without
+going through the normal Tcl evaluation mechanism.
+Substitutions are thus performed on each word exactly once:
+\fItargetCmd\fR and \fIargs\fR were substituted when parsing the command
+that created the alias, and \fIarg1 - argN\fR are substituted when
+the alias's source command is parsed in the source interpreter.
+.PP
+When writing the \fItargetCmd\fRs for aliases in safe interpreters,
+it is very important that the arguments to that command never be
+evaluated or substituted, since this would provide an escape
+mechanism whereby the slave interpreter could execute arbitrary
+code in the master.  This in turn would compromise the security
+of the system.
+.SH "HIDDEN COMMANDS"
+.PP
+Safe interpreters greatly restrict the functionality available to Tcl
+programs executing within them.
+Allowing the untrusted Tcl program to have direct access to this
+functionality is unsafe, because it can be used for a variety of
+attacks on the environment.
+However, there are times when there is a legitimate need to use the
+dangerous functionality in the context of the safe interpreter. For
+example, sometimes a program must be \fBsource\fRd into the interpreter.
+Another example is Tk, where windows are bound to the hierarchy of windows
+for a specific interpreter; some potentially dangerous functions, e.g.
+window management, must be performed on these windows within the
+interpreter context.
+.PP
+The \fBinterp\fR command provides a solution to this problem in the form of
+\fIhidden commands\fR. Instead of removing the dangerous commands entirely
+from a safe interpreter, these commands are hidden so they become
+unavailable to Tcl scripts executing in the interpreter. However, such
+hidden commands can be invoked by any trusted ancestor of the safe
+interpreter, in the context of the safe interpreter, using \fBinterp
+invoke\fR. Hidden commands and exposed commands reside in separate name
+spaces. It is possible to define a hidden command and an exposed command by
+the same name within one interpreter.
+.PP
+Hidden commands in a slave interpreter can be invoked in the body of
+procedures called in the master during alias invocation. For example, an
+alias for \fBsource\fR could be created in a slave interpreter. When it is
+invoked in the slave interpreter, a procedure is called in the master
+interpreter to check that the operation is allowable (e.g. it asks to
+source a file that the slave interpreter is allowed to access). The
+procedure then it invokes the hidden \fBsource\fR command in the slave
+interpreter to actually source in the contents of the file. Note that two
+commands named \fBsource\fR exist in the slave interpreter: the alias, and
+the hidden command.
+.PP
+Because a master interpreter may invoke a hidden command as part of
+handling an alias invocation, great care must be taken to avoid evaluating
+any arguments passed in through the alias invocation.
+Otherwise, malicious slave interpreters could cause a trusted master
+interpreter to execute dangerous commands on their behalf. See the section
+on \fBALIAS INVOCATION\fR for a more complete discussion of this topic.
+To help avoid this problem, no substitutions or evaluations are
+applied to arguments of \fBinterp invokehidden\fR.
+.PP
+Safe interpreters are not allowed to invoke hidden commands in themselves
+or in their descendants. This prevents safe slaves from gaining access to
+hidden functionality in themselves or their descendants.
+.PP
+The set of hidden commands in an interpreter can be manipulated by a trusted
+interpreter using \fBinterp expose\fR and \fBinterp hide\fR. The \fBinterp
+expose\fR command moves a hidden command to the
+set of exposed commands in the interpreter identified by \fIpath\fR,
+potentially renaming the command in the process. If an exposed command by
+the targeted name already exists, the operation fails. Similarly,
+\fBinterp hide\fR moves an exposed command to the set of hidden commands in
+that interpreter. Safe interpreters are not allowed to move commands
+between the set of hidden and exposed commands, in either themselves or
+their descendants.
+.PP
+Currently, the names of hidden commands cannot contain namespace
+qualifiers, and you must first rename a command in a namespace to the
+global namespace before you can hide it.
+Commands to be hidden by \fBinterp hide\fR are looked up in the global
+namespace even if the current namespace is not the global one. This
+prevents slaves from fooling a master interpreter into hiding the wrong
+command, by making the current namespace be different from the global one.
+.SH "RESOURCE LIMITS"
+.PP
+Every interpreter has two kinds of resource limits that may be imposed by any
+master interpreter upon its slaves. Command limits (of type \fBcommand\fR)
+restrict the total number of Tcl commands that may be executed by an
+interpreter (as can be inspected via the \fBinfo cmdcount\fR command), and
+time limits (of type \fBtime\fR) place a limit by which execution within the
+interpreter must complete. Note that time limits are expressed as
+\fIabsolute\fR times (as in \fBclock seconds\fR) and not relative times (as in
+\fBafter\fR) because they may be modified after creation.
+.PP
+When a limit is exceeded for an interpreter, first any handler callbacks
+defined by master interpreters are called. If those callbacks increase or
+remove the limit, execution within the (previously) limited interpreter
+continues. If the limit is still in force, an error is generated at that point
+and normal processing of errors within the interpreter (by the \fBcatch\fR
+command) is disabled, so the error propagates outwards (building a stack-trace
+as it goes) to the point where the limited interpreter was invoked (e.g. by
+\fBinterp eval\fR) where it becomes the responsibility of the calling code to
+catch and handle.
+.SS "LIMIT OPTIONS"
+.PP
+Every limit has a number of options associated with it, some of which are
+common across all kinds of limits, and others of which are particular to the
+kind of limit.
+.TP
+\fB\-command\fR
+.
+This option (common for all limit types) specifies (if non-empty) a Tcl script
+to be executed in the global namespace of the interpreter reading and writing
+the option when the particular limit in the limited interpreter is exceeded.
+The callback may modify the limit on the interpreter if it wishes the limited
+interpreter to continue executing. If the callback generates an exception, it
+is reported through the background exception mechanism (see
+\fBBACKGROUND EXCEPTION HANDLING\fR).
+Note that the callbacks defined by one interpreter are
+completely isolated from the callbacks defined by another, and that the order
+in which those callbacks are called is undefined.
+.TP
+\fB\-granularity\fR
+.
+This option (common for all limit types) specifies how frequently (out of the
+points when the Tcl interpreter is in a consistent state where limit checking
+is possible) that the limit is actually checked. This allows the tuning of how
+frequently a limit is checked, and hence how often the limit-checking overhead
+(which may be substantial in the case of time limits) is incurred.
+.TP
+\fB\-milliseconds\fR
+.
+This option specifies the number of milliseconds after the moment defined in
+the \fB\-seconds\fR option that the time limit will fire. It should only ever
+be specified in conjunction with the \fB\-seconds\fR option (whether it was
+set previously or is being set this invocation.)
+.TP
+\fB\-seconds\fR
+.
+This option specifies the number of seconds after the epoch (see \fBclock
+seconds\fR) that the time limit for the interpreter will be triggered. The
+limit will be triggered at the start of the second unless specified at a
+sub-second level using the \fB\-milliseconds\fR option. This option may be the
+empty string, which indicates that a time limit is not set for the
+interpreter.
+.TP
+\fB\-value\fR
+.
+This option specifies the number of commands that the interpreter may execute
+before triggering the command limit. This option may be the empty string,
+which indicates that a command limit is not set for the interpreter.
+.PP
+Where an interpreter with a resource limit set on it creates a slave
+interpreter, that slave interpreter will have resource limits imposed on it
+that are at least as restrictive as the limits on the creating master
+interpreter. If the master interpreter of the limited master wishes to relax
+these conditions, it should hide the \fBinterp\fR command in the child and
+then use aliases and the \fBinterp invokehidden\fR subcommand to provide such
+access as it chooses to the \fBinterp\fR command to the limited master as
+necessary.
+.SH "BACKGROUND EXCEPTION HANDLING"
+.PP
+When an exception happens in a situation where it cannot be reported directly up
+the stack (e.g. when processing events in an \fBupdate\fR or \fBvwait\fR call)
+the exception is instead reported through the background exception handling mechanism.
+Every interpreter has a background exception handler registered; the default exception
+handler arranges for the \fBbgerror\fR command in the interpreter's global
+namespace to be called, but other exception handlers may be installed and process
+background exceptions in substantially different ways.
+.PP
+A background exception handler consists of a non-empty list of words to which will
+be appended two further words at invocation time. The first word will be the
+interpreter result at time of the exception, typically an error message,
+and the second will be the dictionary of return options at the time of
+the exception.  These are the same values that \fBcatch\fR can capture
+when it controls script evaluation in a non-background situation.
+The resulting list will then be executed
+in the interpreter's global namespace without further substitutions being
+performed.
+.SH CREDITS
+The safe interpreter mechanism is based on the Safe-Tcl prototype implemented
+by Nathaniel Borenstein and Marshall Rose.

+.PP
+This command treats the variable given by \fIvarName\fR as a list

+.SH INTRODUCTION
+.PP
+Tcl includes a library of Tcl procedures for commonly-needed functions.
+The procedures defined in the Tcl library are generic ones suitable
+for use by many different applications.
+The location of the Tcl library is returned by the \fBinfo library\fR
+command.
+In addition to the Tcl library, each application will normally have
+its own library of support procedures as well;  the location of this
+library is normally given by the value of the \fB$\fIapp\fB_library\fR
+global variable, where \fIapp\fR is the name of the application.
+For example, the location of the Tk library is kept in the variable
+\fBtk_library\fR.
+.PP
+To access the procedures in the Tcl library, an application should
+source the file \fBinit.tcl\fR in the library, for example with
+the Tcl command
+.PP
+.CS
+\fBsource [file join [info library] init.tcl]\fR
+.CE
+.PP
+If the library procedure \fBTcl_Init\fR is invoked from an application's
+\fBTcl_AppInit\fR procedure, this happens automatically.
+The code in \fBinit.tcl\fR will define the \fBunknown\fR procedure
+and arrange for the other procedures to be loaded on-demand using
+the auto-load mechanism defined below.
+.SH "COMMAND PROCEDURES"
+.PP
+The following procedures are provided in the Tcl library:
+.TP
+\fBauto_execok \fIcmd\fR
+Determines whether there is an executable file or shell builtin
+by the name \fIcmd\fR.  If so, it returns a list of arguments to be
+passed to \fBexec\fR to execute the executable file or shell builtin
+named by \fIcmd\fR.  If not, it returns an empty string.  This command
+examines the directories in the current search path (given by the PATH
+environment variable) in its search for an executable file named
+\fIcmd\fR.  On Windows platforms, the search is expanded with the same
+directories and file extensions as used by \fBexec\fR. \fBAuto_execok\fR
+remembers information about previous searches in an array named
+\fBauto_execs\fR;  this avoids the path search in future calls for the
+same \fIcmd\fR.  The command \fBauto_reset\fR may be used to force
+\fBauto_execok\fR to forget its cached information.
+.TP
+\fBauto_import \fIpattern\fR
+\fBAuto_import\fR is invoked during \fBnamespace import\fR to see if
+the imported commands specified by \fIpattern\fR reside in an
+autoloaded library.  If so, the commands are loaded so that they will
+be available to the interpreter for creating the import links.  If the
+commands do not reside in an autoloaded library, \fBauto_import\fR
+does nothing.  The pattern matching is performed according to the
+matching rules of \fBnamespace import\fR.
+.TP
+\fBauto_load \fIcmd\fR
+This command attempts to load the definition for a Tcl command named
+\fIcmd\fR.  To do this, it searches an \fIauto-load path\fR, which is
+a list of one or more directories.  The auto-load path is given by the
+global variable \fBauto_path\fR if it exists.  If there is no
+\fBauto_path\fR variable, then the TCLLIBPATH environment variable is
+used, if it exists.  Otherwise the auto-load path consists of just the
+Tcl library directory.  Within each directory in the auto-load path
+there must be a file \fBtclIndex\fR that describes one or more
+commands defined in that directory and a script to evaluate to load
+each of the commands.  The \fBtclIndex\fR file should be generated
+with the \fBauto_mkindex\fR command.  If \fIcmd\fR is found in an
+index file, then the appropriate script is evaluated to create the
+command.  The \fBauto_load\fR command returns 1 if \fIcmd\fR was
+successfully created.  The command returns 0 if there was no index
+entry for \fIcmd\fR or if the script did not actually define \fIcmd\fR
+(e.g. because index information is out of date).  If an error occurs
+while processing the script, then that error is returned.
+\fBAuto_load\fR only reads the index information once and saves it in
+the array \fBauto_index\fR;  future calls to \fBauto_load\fR check for
+\fIcmd\fR in the array rather than re-reading the index files.  The
+cached index information may be deleted with the command
+\fBauto_reset\fR.  This will force the next \fBauto_load\fR command to
+reload the index database from disk.
+.TP
+\fBauto_mkindex \fIdir pattern pattern ...\fR
+.
+Generates an index suitable for use by \fBauto_load\fR.  The command
+searches \fIdir\fR for all files whose names match any of the
+\fIpattern\fR arguments (matching is done with the \fBglob\fR
+command), generates an index of all the Tcl command procedures defined
+in all the matching files, and stores the index information in a file
+named \fBtclIndex\fR in \fIdir\fR. If no pattern is given a pattern of
+\fB*.tcl\fR will be assumed.  For example, the command
+.RS
+.PP
+.CS
+\fBauto_mkindex foo *.tcl\fR
+.CE
+.PP
+will read all the \fB.tcl\fR files in subdirectory \fBfoo\fR and
+generate a new index file \fBfoo/tclIndex\fR.
+.PP
+\fBAuto_mkindex\fR parses the Tcl scripts by sourcing them into a
+slave interpreter and monitoring the proc and namespace commands that
+are executed.  Extensions can use the (undocumented)
+auto_mkindex_parser package to register other commands that can
+contribute to the auto_load index. You will have to read through
+auto.tcl to see how this works.
+.PP
+\fBAuto_mkindex_old\fR
+(which has the same syntax as \fBauto_mkindex\fR)
+parses the Tcl scripts in a relatively
+unsophisticated way:  if any line contains the word
+.QW \fBproc\fR
+as its first characters then it is assumed to be a procedure
+definition and the next word of the line is taken as the
+procedure's name.
+Procedure definitions that do not appear in this way (e.g.\ they
+have spaces before the \fBproc\fR) will not be indexed.  If your 
+script contains
+.QW dangerous
+code, such as global initialization
+code or procedure names with special characters like \fB$\fR,
+\fB*\fR, \fB[\fR or \fB]\fR, you are safer using \fBauto_mkindex_old\fR.
+.RE
+.TP
+\fBauto_reset\fR
+.
+Destroys all the information cached by \fBauto_execok\fR and
+\fBauto_load\fR.  This information will be re-read from disk the next
+time it is needed.  \fBAuto_reset\fR also deletes any procedures
+listed in the auto-load index, so that fresh copies of them will be
+loaded the next time that they are used.
+.TP
+\fBauto_qualify \fIcommand namespace\fR
+Computes a list of fully qualified names for \fIcommand\fR.  This list
+mirrors the path a standard Tcl interpreter follows for command
+lookups:  first it looks for the command in the current namespace, and
+then in the global namespace.  Accordingly, if \fIcommand\fR is
+relative and \fInamespace\fR is not \fB::\fR, the list returned has
+two elements:  \fIcommand\fR scoped by \fInamespace\fR, as if it were
+a command in the \fInamespace\fR namespace; and \fIcommand\fR as if it
+were a command in the global namespace.  Otherwise, if either
+\fIcommand\fR is absolute (it begins with \fB::\fR), or
+\fInamespace\fR is \fB::\fR, the list contains only \fIcommand\fR as
+if it were a command in the global namespace.
+.RS
+.PP
+\fBAuto_qualify\fR is used by the auto-loading facilities in Tcl, both
+for producing auto-loading indexes such as \fIpkgIndex.tcl\fR, and for
+performing the actual auto-loading of functions at runtime.
+.RE
+.TP
+\fBtcl_findLibrary \fIbasename version patch initScript enVarName varName\fR
+This is a standard search procedure for use by extensions during
+their initialization.  They call this procedure to look for their
+script library in several standard directories.
+The last component of the name of the library directory is 
+normally \fIbasenameversion\fR
+(e.g., tk8.0), but it might be
+.QW library
+when in the build hierarchies.
+The \fIinitScript\fR file will be sourced into the interpreter
+once it is found.  The directory in which this file is found is
+stored into the global variable \fIvarName\fR.
+If this variable is already defined (e.g., by C code during
+application initialization) then no searching is done.
+Otherwise the search looks in these directories:
+the directory named by the environment variable \fIenVarName\fR;
+relative to the Tcl library directory;
+relative to the executable file in the standard installation
+bin or bin/\fIarch\fR directory;
+relative to the executable file in the current build tree;
+relative to the executable file in a parallel build tree.
+.TP
+\fBparray \fIarrayName\fR
+Prints on standard output the names and values of all the elements
+in the array \fIarrayName\fR.
+\fIArrayName\fR must be an array accessible to the caller of \fBparray\fR.
+It may be either local or global.
+.TP
+\fBtcl_endOfWord \fIstr start\fR
+Returns the index of the first end-of-word location that occurs after
+a starting index \fIstart\fR in the string \fIstr\fR.  An end-of-word
+location is defined to be the first non-word character following the
+first word character after the starting point.  Returns -1 if there
+are no more end-of-word locations after the starting point.  See the
+description of \fBtcl_wordchars\fR and \fBtcl_nonwordchars\fR below
+for more details on how Tcl determines which characters are word
+characters.
+.TP
+\fBtcl_startOfNextWord \fIstr start\fR
+Returns the index of the first start-of-word location that occurs
+after a starting index \fIstart\fR in the string \fIstr\fR.  A
+start-of-word location is defined to be the first word character
+following a non-word character.  Returns \-1 if there are no more
+start-of-word locations after the starting point.
+.TP
+\fBtcl_startOfPreviousWord \fIstr start\fR
+Returns the index of the first start-of-word location that occurs
+before a starting index \fIstart\fR in the string \fIstr\fR.  Returns
+\-1 if there are no more start-of-word locations before the starting
+point.
+.TP
+\fBtcl_wordBreakAfter \fIstr start\fR
+Returns the index of the first word boundary after the starting index
+\fIstart\fR in the string \fIstr\fR.  Returns \-1 if there are no more
+boundaries after the starting point in the given string.  The index
+returned refers to the second character of the pair that comprises a
+boundary.
+.TP
+\fBtcl_wordBreakBefore \fIstr start\fR
+Returns the index of the first word boundary before the starting index
+\fIstart\fR in the string \fIstr\fR.  Returns \-1 if there are no more
+boundaries before the starting point in the given string.  The index
+returned refers to the second character of the pair that comprises a
+boundary.
+.SH "VARIABLES"
+.PP
+The following global variables are defined or used by the procedures in
+the Tcl library. They fall into two broad classes, handling unknown
+commands and packages, and determining what are words.
+.SS "AUTOLOADING AND PACKAGE MANAGEMENT VARIABLES"
+.TP
+\fBauto_execs\fR
+Used by \fBauto_execok\fR to record information about whether
+particular commands exist as executable files.
+.TP
+\fBauto_index\fR
+Used by \fBauto_load\fR to save the index information read from
+disk.
+.TP
+\fBauto_noexec\fR
+If set to any value, then \fBunknown\fR will not attempt to auto-exec
+any commands.
+.TP
+\fBauto_noload\fR
+If set to any value, then \fBunknown\fR will not attempt to auto-load
+any commands.
+.TP
+\fBauto_path\fR
+If set, then it must contain a valid Tcl list giving directories to
+search during auto-load operations.
+This variable is initialized during startup to contain, in order:
+the directories listed in the \fBTCLLIBPATH\fR environment variable,
+the directory named by the \fBtcl_library\fR variable,
+the parent directory of \fBtcl_library\fR,
+the directories listed in the \fBtcl_pkgPath\fR variable.
+.TP
+\fBenv(TCL_LIBRARY)\fR
+If set, then it specifies the location of the directory containing
+library scripts (the value of this variable will be
+assigned to the \fBtcl_library\fR variable and therefore returned by
+the command \fBinfo library\fR).  If this variable is not set then
+a default value is used.
+.TP
+\fBenv(TCLLIBPATH)\fR
+If set, then it must contain a valid Tcl list giving directories to
+search during auto-load operations.  Directories must be specified in 
+Tcl format, using
+.QW /
+as the path separator, regardless of platform.
+This variable is only used when initializing the \fBauto_path\fR variable.
+.SS "WORD BOUNDARY DETERMINATION VARIABLES"
+These variables are only used in the \fBtcl_endOfWord\fR,
+\fBtcl_startOfNextWord\fR, \fBtcl_startOfPreviousWord\fR,
+\fBtcl_wordBreakAfter\fR, and \fBtcl_wordBreakBefore\fR commands.
+.TP
+\fBtcl_nonwordchars\fR
+This variable contains a regular expression that is used by routines
+like \fBtcl_endOfWord\fR to identify whether a character is part of a
+word or not.  If the pattern matches a character, the character is
+considered to be a non-word character.  On Windows platforms, spaces,
+tabs, and newlines are considered non-word characters.  Under Unix,
+everything but numbers, letters and underscores are considered
+non-word characters.
+.TP
+\fBtcl_wordchars\fR
+This variable contains a regular expression that is used by routines
+like \fBtcl_endOfWord\fR to identify whether a character is part of a
+word or not.  If the pattern matches a character, the character is
+considered to be a word character.  On Windows platforms, words are
+comprised of any character that is not a space, tab, or newline.  Under
+Unix, words are comprised of numbers, letters or underscores.

+.SH NAME
+lindex \- Retrieve an element from a list
+.SH SYNOPSIS
+\fBlindex \fIlist ?index ...?\fR
+.BE
+.SH DESCRIPTION
+.PP
+The \fBlindex\fR command accepts a parameter, \fIlist\fR, which
+it treats as a Tcl list. It also accepts zero or more \fIindices\fR into
+the list.  The indices may be presented either consecutively on the
+command line, or grouped in a
+Tcl list and presented as a single argument.
+.PP
+If no indices are presented, the command takes the form:
+.PP
+.CS
+\fBlindex \fIlist\fR
+.CE
+.PP
+or
+.PP
+.CS
+\fBlindex \fIlist\fR {}
+.CE
+.PP
+In this case, the return value of \fBlindex\fR is simply the value of the
+\fIlist\fR parameter.
+.PP
+When presented with a single index, the \fBlindex\fR command
+treats \fIlist\fR as a Tcl list and returns the
+\fIindex\fR'th element from it (0 refers to the first element of the list).
+In extracting the element, \fBlindex\fR observes the same rules
+concerning braces and quotes and backslashes as the Tcl command
+interpreter; however, variable
+substitution and command substitution do not occur.
+If \fIindex\fR is negative or greater than or equal to the number
+of elements in \fIvalue\fR, then an empty
+string is returned.
+The interpretation of each simple \fIindex\fR value is the same as 
+for the command \fBstring index\fR, supporting simple index
+arithmetic and indices relative to the end of the list.
+.PP
+If additional \fIindex\fR arguments are supplied, then each argument is
+used in turn to select an element from the previous indexing operation,
+allowing the script to select elements from sublists.  The command,
+.PP
+.CS
+\fBlindex\fR $a 1 2 3
+.CE
+.PP
+or
+.PP
+.CS
+\fBlindex\fR $a {1 2 3}
+.CE
+.PP
+is synonymous with
+.PP
+.CS
+\fBlindex\fR [\fBlindex\fR [\fBlindex\fR $a 1] 2] 3
+.CE
+.SH EXAMPLES
+.PP
+Lists can be indexed into from either end:
+.PP
+.CS
+\fBlindex\fR {a b c} 0
+      \fI\(-> a\fR
+\fBlindex\fR {a b c} 2
+      \fI\(-> c\fR
+\fBlindex\fR {a b c} end
+      \fI\(-> c\fR
+\fBlindex\fR {a b c} end-1
+      \fI\(-> b\fR
+.CE
+.PP
+Lists or sequences of indices allow selection into lists of lists:
+.PP
+.CS
+\fBlindex\fR {a b c}
+      \fI\(-> a b c\fR
+\fBlindex\fR {a b c} {}
+      \fI\(-> a b c\fR
+\fBlindex\fR {{a b c} {d e f} {g h i}} 2 1
+      \fI\(-> h\fR
+\fBlindex\fR {{a b c} {d e f} {g h i}} {2 1}
+      \fI\(-> h\fR
+\fBlindex\fR {{{a b} {c d}} {{e f} {g h}}} 1 1 0
+      \fI\(-> g\fR
+\fBlindex\fR {{{a b} {c d}} {{e f} {g h}}} {1 1 0}
+      \fI\(-> g\fR
+.CE
+.PP
+List indices may also perform limited computation, adding or subtracting fixed
+amounts from other indices:
+.PP
+.CS
+set idx 1
+\fBlindex\fR {a b c d e f} $idx+2

+.SH NAME
+linsert \- Insert elements into a list
+.SH SYNOPSIS
+\fBlinsert \fIlist index \fR?\fIelement element ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command produces a new list from \fIlist\fR by inserting all of the
+\fIelement\fR arguments just before the \fIindex\fR'th element of
+\fIlist\fR.  Each \fIelement\fR argument will become a separate element of
+the new list.  If \fIindex\fR is less than or equal to zero, then the new
+elements are inserted at the beginning of the list, and if \fIindex\fR is
+greater or equal to the length of \fIlist\fR, it is as if it was \fBend\fR.
+As with \fBstring index\fR, the \fIindex\fR value supports both simple index
+arithmetic and end-relative indexing.
+.PP
+Subject to the restrictions that indices must refer to locations inside the
+list and that the \fIelement\fRs will always be inserted in order, insertions
+are done so that when \fIindex\fR is start-relative, the first \fIelement\fR
+will be at that index in the resulting list, and when \fIindex\fR is
+end-relative, the last \fIelement\fR will be at that index in the resulting
+list.
+.SH EXAMPLE
+.PP
+Putting some values into a list, first indexing from the start and

+.SH NAME
+lmap \- Iterate over all elements in one or more lists and collect results
+.SH SYNOPSIS
+\fBlmap \fIvarname list body\fR
+.br
+\fBlmap \fIvarlist1 list1\fR ?\fIvarlist2 list2 ...\fR? \fIbody\fR
+.BE
+.SH DESCRIPTION
+.PP
+The \fBlmap\fR command implements a loop where the loop variable(s) take on
+values from one or more lists, and the loop returns a list of results
+collected from each iteration.
+.PP
+In the simplest case there is one loop variable, \fIvarname\fR, and one list,
+\fIlist\fR, that is a list of values to assign to \fIvarname\fR. The
+\fIbody\fR argument is a Tcl script. For each element of \fIlist\fR (in order
+from first to last), \fBlmap\fR assigns the contents of the element to
+\fIvarname\fR as if the \fBlindex\fR command had been used to extract the
+element, then calls the Tcl interpreter to execute \fIbody\fR. If execution of
+the body completes normally then the result of the body is appended to an
+accumulator list. \fBlmap\fR returns the accumulator list.
+.PP
+In the general case there can be more than one value list (e.g., \fIlist1\fR
+and \fIlist2\fR), and each value list can be associated with a list of loop
+variables (e.g., \fIvarlist1\fR and \fIvarlist2\fR). During each iteration of
+the loop the variables of each \fIvarlist\fR are assigned consecutive values
+from the corresponding \fIlist\fR. Values in each \fIlist\fR are used in order
+from first to last, and each value is used exactly once. The total number of
+loop iterations is large enough to use up all the values from all the value
+lists. If a value list does not contain enough elements for each of its loop
+variables in each iteration, empty values are used for the missing elements.
+.PP
+The \fBbreak\fR and \fBcontinue\fR statements may be invoked inside
+\fIbody\fR, with the same effect as in the \fBfor\fR and \fBforeach\fR
+commands. In these cases the body does not complete normally and the result is
+not appended to the accumulator list.
+.SH EXAMPLES
+.PP
+Zip lists together:
+.PP
+.CS
+set list1 {a b c d}
+set list2 {1 2 3 4}
+set zipped [\fBlmap\fR a $list1 b $list2 {list $a $b}] 
+# The value of zipped is "{a 1} {b 2} {c 3} {d 4}"
+.CE

+Filter a list to remove odd values:
+.PP
+.CS

+.SH NAME
+load \- Load machine code and initialize new commands
+.SH SYNOPSIS
+\fBload\fR ?\fB\-global\fR? ?\fB\-lazy\fR? ?\fB\-\-\fR? \fIfileName\fR
+.br
+\fBload\fR ?\fB\-global\fR? ?\fB\-lazy\fR? ?\fB\-\-\fR? \fIfileName packageName\fR
+.br
+\fBload\fR ?\fB\-global\fR? ?\fB\-lazy\fR? ?\fB\-\-\fR? \fIfileName packageName interp\fR
+.BE
+.SH DESCRIPTION
+.PP
+This command loads binary code from a file into the
+application's address space and calls an initialization procedure
+in the package to incorporate it into an interpreter.  \fIfileName\fR
+is the name of the file containing the code;  its exact form varies
+from system to system but on most systems it is a shared library,
+such as a \fB.so\fR file under Solaris or a DLL under Windows.
+\fIpackageName\fR is the name of the package, and is used to
+compute the name of an initialization procedure.
+\fIinterp\fR is the path name of the interpreter into which to load
+the package (see the \fBinterp\fR manual entry for details);
+if \fIinterp\fR is omitted, it defaults to the
+interpreter in which the \fBload\fR command was invoked.
+.PP
+Once the file has been loaded into the application's address space,
+one of two initialization procedures will be invoked in the new code.
+Typically the initialization procedure will add new commands to a
+Tcl interpreter.
+The name of the initialization procedure is determined by
+\fIpackageName\fR and whether or not the target interpreter
+is a safe one.  For normal interpreters the name of the initialization
+procedure will have the form \fIpkg\fB_Init\fR, where \fIpkg\fR
+is the same as \fIpackageName\fR except that the first letter is
+converted to upper case and all other letters
+are converted to lower case.  For example, if \fIpackageName\fR is
+\fBfoo\fR or \fBFOo\fR, the initialization procedure's name will
+be \fBFoo_Init\fR.
+.PP
+If the target interpreter is a safe interpreter, then the name
+of the initialization procedure will be \fIpkg\fB_SafeInit\fR
+instead of \fIpkg\fB_Init\fR.
+The \fIpkg\fB_SafeInit\fR function should be written carefully, so that it
+initializes the safe interpreter only with partial functionality provided
+by the package that is safe for use by untrusted code. For more information
+on Safe\-Tcl, see the \fBsafe\fR manual entry.
+.PP
+The initialization procedure must match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_PackageInitProc\fR(
+        Tcl_Interp *\fIinterp\fR);
+.CE
+.PP
+The \fIinterp\fR argument identifies the interpreter in which the
+package is to be loaded.  The initialization procedure must return
+\fBTCL_OK\fR or \fBTCL_ERROR\fR to indicate whether or not it completed
+successfully;  in the event of an error it should set the interpreter's result
+to point to an error message.  The result of the \fBload\fR command
+will be the result returned by the initialization procedure.
+.PP
+The actual loading of a file will only be done once for each \fIfileName\fR
+in an application.  If a given \fIfileName\fR is loaded into multiple
+interpreters, then the first \fBload\fR will load the code and
+call the initialization procedure;  subsequent \fBload\fRs will
+call the initialization procedure without loading the code again.
+For Tcl versions lower than 8.5, it is not possible to unload or reload a
+package. From version 8.5 however, the \fBunload\fR command allows the unloading
+of libraries loaded with \fBload\fR, for libraries that are aware of the
+Tcl's unloading mechanism.
+.PP
+The \fBload\fR command also supports packages that are statically
+linked with the application, if those packages have been registered
+by calling the \fBTcl_StaticPackage\fR procedure.
+If \fIfileName\fR is an empty string, then \fIpackageName\fR must
+be specified.
+.PP
+If \fIpackageName\fR is omitted or specified as an empty string,
+Tcl tries to guess the name of the package.
+This may be done differently on different platforms.
+The default guess, which is used on most UNIX platforms, is to
+take the last element of \fIfileName\fR, strip off the first
+three characters if they are \fBlib\fR, and use any following
+alphabetic and underline characters as the module name.
+For example, the command \fBload libxyz4.2.so\fR uses the module
+name \fBxyz\fR and the command \fBload bin/last.so {}\fR uses the
+module name \fBlast\fR.
+.PP
+If \fIfileName\fR is an empty string, then \fIpackageName\fR must
+be specified.
+The \fBload\fR command first searches for a statically loaded package
+(one that has been registered by calling the \fBTcl_StaticPackage\fR
+procedure) by that name; if one is found, it is used.
+Otherwise, the \fBload\fR command searches for a dynamically loaded
+package by that name, and uses it if it is found.  If several
+different files have been \fBload\fRed with different versions of
+the package, Tcl picks the file that was loaded first.
+.PP
+If \fB\-global\fR is specified preceding the filename, all symbols
+found in the shared library are exported for global use by other
+libraries. The option \fB\-lazy\fR delays the actual loading of
+symbols until their first actual use. The options may be abbreviated.
+The option \fB\-\-\fR indicates the end of the options, and should
+be used if you wish to use a filename which starts with \fB\-\fR
+and you provide a packageName to the \fBload\fR command.
+.PP
+On platforms which do not support the \fB\-global\fR or \fB\-lazy\fR
+options, the options still exist but have no effect. Note that use
+of the \fB\-global\fR or \fB\-lazy\fR option may lead to crashes
+in your application later (in case of symbol conflicts resp. missing
+symbols), which cannot be detected during the \fBload\fR. So, only
+use this when you know what you are doing, you will not get a nice
+error message when something is wrong with the loaded library.
+.SH "PORTABILITY ISSUES"
+.TP
+\fBWindows\fR\0\0\0\0\0
+.
+When a load fails with
+.QW "library not found"
+error, it is also possible
+that a dependent library was not found.  To see the dependent libraries,
+type
+.QW "dumpbin -imports <dllname>"
+in a DOS console to see what the library must import.
+When loading a DLL in the current directory, Windows will ignore
+.QW ./
+as a path specifier and use a search heuristic to find the DLL instead.
+To avoid this, load the DLL with:
+.RS
+.PP
+.CS
+\fBload\fR [file join [pwd] mylib.DLL]
+.CE
+.RE
+.SH BUGS
+.PP
+If the same file is \fBload\fRed by different \fIfileName\fRs, it will
+be loaded into the process's address space multiple times.  The
+behavior of this varies from system to system (some systems may
+detect the redundant loads, others may not).
+.SH EXAMPLE
+.PP
+The following is a minimal extension:
+.PP
+.CS
+#include <tcl.h>
+#include <stdio.h>
+static int fooCmd(ClientData clientData,
+        Tcl_Interp *interp, int objc, Tcl_Obj *const objv[]) {
+    printf("called with %d arguments\en", objc);
+    return TCL_OK;
+}
+int Foo_Init(Tcl_Interp *interp) {
+    if (Tcl_InitStubs(interp, "8.1", 0) == NULL) {
+	return TCL_ERROR;
+    }
+    printf("creating foo command");
+    Tcl_CreateObjCommand(interp, "foo", fooCmd, NULL, NULL);
+    return TCL_OK;
+}
+.CE
+.PP
+When built into a shared/dynamic library with a suitable name
+(e.g. \fBfoo.dll\fR on Windows, \fBlibfoo.so\fR on Solaris and Linux)
+it can then be loaded into Tcl with the following:
+.PP
+.CS
+# Load the extension
+switch $tcl_platform(platform) {
+    windows {
+        \fBload\fR [file join [pwd] foo.dll]
+    }
+    unix {
+        \fBload\fR [file join [pwd] libfoo[info sharedlibextension]]
+    }

+.PP
+\fBlreplace\fR returns a new list formed by replacing one or more elements of

+\fIfirst\fR and \fIlast\fR are index values specifying the first and

+0 refers to the first element of the
+list, and \fBend\fR refers to the last element of the list.
+If \fIlist\fR is empty, then \fIfirst\fR and \fIlast\fR are ignored.
+.PP
+If \fIfirst\fR is less than zero, it is considered to refer to before the
+first element of the list.  For non-empty lists, the element indicated
+by \fIfirst\fR must exist or \fIfirst\fR must indicate before the
+start of the list.
+.PP
+If \fIlast\fR is less than \fIfirst\fR, then any specified elements
+will be inserted into the list at the point specified by \fIfirst\fR
+with no elements being deleted.
+.PP
+The \fIelement\fR arguments specify zero or more new arguments to
+be added to the list in place of those that were deleted.
+Each \fIelement\fR argument will become a separate element of
+the list.  If no \fIelement\fR arguments are specified, then the elements
+between \fIfirst\fR and \fIlast\fR are simply deleted.  If \fIlist\fR
+is empty, any \fIelement\fR arguments are added to the end of the list.

+.PP
+This command searches the elements of \fIlist\fR to see if one

+of the first matching element
+(unless the options \fB\-all\fR or \fB\-inline\fR are specified.)
+If not, the command returns \fB\-1\fR.  The \fIoption\fR arguments
+indicates how the elements of the list are to be matched against
+\fIpattern\fR and must have one of the values below:
+.SS "MATCHING STYLE OPTIONS"
+.PP
+If all matching style options are omitted, the default matching style
+is \fB\-glob\fR.  If more than one matching style is specified, the
+last matching style given takes precedence.
+.TP
+\fB\-exact\fR
+.
+\fIPattern\fR is a literal string that is compared for exact equality
+against each list element.

+\fB\-glob\fR

+\fIPattern\fR is a glob-style pattern which is matched against each list
+element using the same rules as the \fBstring match\fR command.
+.TP
+\fB\-regexp\fR
+.
+\fIPattern\fR is treated as a regular expression and matched against
+each list element using the rules described in the \fBre_syntax\fR
+reference page.
+.TP
+\fB\-sorted\fR
+.
+The list elements are in sorted order.  If this option is specified,
+\fBlsearch\fR will use a more efficient searching algorithm to search
+\fIlist\fR.  If no other options are specified, \fIlist\fR is assumed
+to be sorted in increasing order, and to contain ASCII strings.  This
+option is mutually exclusive with \fB\-glob\fR and \fB\-regexp\fR, and

+These options may be given with all matching styles.
+.TP
+\fB\-all\fR
+.
+Changes the result to be the list of all matching indices (or all matching
+values if \fB\-inline\fR is specified as well.) If indices are returned, the
+indices will be in numeric order. If values are returned, the order of the
+values will be the order of those values within the input \fIlist\fR.
+.TP
+\fB\-inline\fR
+.
+The matching value is returned instead of its index (or an empty
+string if no value matches.)  If \fB\-all\fR is also specified, then
+the result of the command is the list of all values that matched.
+.TP
+\fB\-not\fR
+.
+This negates the sense of the match, returning the index of the first
+non-matching value in the list.
+.TP
+\fB\-start\fR\0\fIindex\fR
+.
+The list is searched starting at position \fIindex\fR.
+The interpretation of the \fIindex\fR value is the same as
+for the command \fBstring index\fR, supporting simple index
+arithmetic and indices relative to the end of the list.
+.SS "CONTENTS DESCRIPTION OPTIONS"
+.PP
+These options describe how to interpret the items in the list being
+searched.  They are only meaningful when used with the \fB\-exact\fR
+and \fB\-sorted\fR options.  If more than one is specified, the last
+one takes precedence.  The default is \fB\-ascii\fR.
+.TP
+\fB\-ascii\fR
+.
+The list elements are to be examined as Unicode strings (the name is
+for backward-compatibility reasons.)
+.TP
+\fB\-dictionary\fR
+.
+The list elements are to be compared using dictionary-style
+comparisons (see \fBlsort\fR for a fuller description). Note that this
+only makes a meaningful difference from the \fB\-ascii\fR option when
+the \fB\-sorted\fR option is given, because values are only
+dictionary-equal when exactly equal.
+.TP
+\fB\-integer\fR
+.
+The list elements are to be compared as integers.
+.TP
+\fB\-nocase\fR
+.
+Causes comparisons to be handled in a case-insensitive manner.  Has no
+effect if combined with the \fB\-dictionary\fR, \fB\-integer\fR, or 
+\fB\-real\fR options.
+.TP
+\fB\-real\fR
+.
+The list elements are to be compared as floating-point values.
+.SS "SORTED LIST OPTIONS"
+.PP
+These options (only meaningful with the \fB\-sorted\fR option) specify
+how the list is sorted.  If more than one is given, the last one takes
+precedence.  The default option is \fB\-increasing\fR.
+.TP
+\fB\-decreasing\fR
+.
+The list elements are sorted in decreasing order.  This option is only
+meaningful when used with \fB\-sorted\fR.
+.TP
+\fB\-increasing\fR
+.
+The list elements are sorted in increasing order.  This option is only
+meaningful when used with \fB\-sorted\fR.
+.TP
+\fB\-bisect\fR
+.VS 8.6
+Inexact search when the list elements are in sorted order. For an increasing
+list the last index where the element is less than or equal to the pattern
+is returned. For a decreasing list the last index where the element is greater
+than or equal to the pattern is returned. If the pattern is before the first
+element or the list is empty, -1 is returned.
+This option implies \fB\-sorted\fR and cannot be used with either \fB\-all\fR
+or \fB\-not\fR.
+.VE 8.6
+.SS "NESTED LIST OPTIONS"
+.PP
+These options are used to search lists of lists.  They may be used
+with any other options.
+.TP
+\fB\-index\fR\0\fIindexList\fR
+.
+This option is designed for use when searching within nested lists.
+The \fIindexList\fR argument gives a path of indices (much as might be
+used with the \fBlindex\fR or \fBlset\fR commands) within each element
+to allow the location of the term being matched against.
+.TP
+\fB\-subindices\fR
+.
+If this option is given, the index result from this command (or every
+index result when \fB\-all\fR is also specified) will be a complete
+path (suitable for use with \fBlindex\fR or \fBlset\fR) within the
+overall list to the term found.  This option has no effect unless the
+\fB\-index\fR is also specified, and is just a convenience short-cut.

+.SH NAME
+lset \- Change an element in a list
+.SH SYNOPSIS
+\fBlset \fIvarName ?index ...? newValue\fR
+.BE
+.SH DESCRIPTION
+.PP
+The \fBlset\fR command accepts a parameter, \fIvarName\fR, which
+it interprets as the name of a variable containing a Tcl list. 
+It also accepts zero or more \fIindices\fR into
+the list.  The indices may be presented either consecutively on the
+command line, or grouped in a
+Tcl list and presented as a single argument.
+Finally, it accepts a new value for an element of \fIvarName\fR.
+.PP
+If no indices are presented, the command takes the form:
+.PP
+.CS
+\fBlset\fR varName newValue
+.CE
+.PP
+or
+.PP
+.CS
+\fBlset\fR varName {} newValue
+.CE
+.PP
+In this case, \fInewValue\fR replaces the old value of the variable
+\fIvarName\fR.
+.PP
+When presented with a single index, the \fBlset\fR command
+treats the content of the \fIvarName\fR variable as a Tcl list.
+It addresses the \fIindex\fR'th element in it 
+(0 refers to the first element of the list).
+When interpreting the list, \fBlset\fR observes the same rules
+concerning braces and quotes and backslashes as the Tcl command
+interpreter; however, variable
+substitution and command substitution do not occur.
+The command constructs a new list in which the designated element is
+replaced with \fInewValue\fR.  This new list is stored in the
+variable \fIvarName\fR, and is also the return value from the \fBlset\fR
+command.
+.PP
+If \fIindex\fR is negative or greater than the number
+of elements in \fI$varName\fR, then an error occurs.
+.PP
+If \fIindex\fR is equal to the number of elements in \fI$varName\fR,
+then the given element is appended to the list.
+.PP
+The interpretation of each simple \fIindex\fR value is the same as
+for the command \fBstring index\fR, supporting simple index
+arithmetic and indices relative to the end of the list.
+.PP
+If additional \fIindex\fR arguments are supplied, then each argument is
+used in turn to address an element within a sublist designated
+by the previous indexing operation,
+allowing the script to alter elements in sublists (or append elements
+to sublists).  The command,
+.PP
+.CS
+\fBlset\fR a 1 2 newValue
+.CE
+.PP
+or
+.PP
+.CS
+\fBlset\fR a {1 2} newValue
+.CE
+.PP
+replaces element 2 of sublist 1 with \fInewValue\fR.
+.PP
+The integer appearing in each \fIindex\fR argument must be greater
+than or equal to zero.  The integer appearing in each \fIindex\fR
+argument must be less than or equal to the length of the corresponding
+list.  In other words, the \fBlset\fR command can change the size
+of a list only by appending an element (setting the one after the current
+end).  If an index is outside the permitted range, an error is reported.
+.SH EXAMPLES
+.PP
+In each of these examples, the initial value of \fIx\fR is:
+.PP
+.CS
+set x [list [list a b c] [list d e f] [list g h i]]
+      \fI\(-> {a b c} {d e f} {g h i}\fR
+.CE
+.PP
+The indicated return value also becomes the new value of \fIx\fR
+(except in the last case, which is an error which leaves the value of
+\fIx\fR unchanged.)
+.PP
+.CS
+\fBlset\fR x {j k l}
+      \fI\(-> j k l\fR
+\fBlset\fR x {} {j k l}
+      \fI\(-> j k l\fR
+\fBlset\fR x 0 j
+      \fI\(-> j {d e f} {g h i}\fR
+\fBlset\fR x 2 j
+      \fI\(-> {a b c} {d e f} j\fR
+\fBlset\fR x end j
+      \fI\(-> {a b c} {d e f} j\fR
+\fBlset\fR x end-1 j
+      \fI\(-> {a b c} j {g h i}\fR
+\fBlset\fR x 2 1 j
+      \fI\(-> {a b c} {d e f} {g j i}\fR
+\fBlset\fR x {2 1} j
+      \fI\(-> {a b c} {d e f} {g j i}\fR
+\fBlset\fR x {2 3} j
+      \fI\(-> list index out of range\fR
+.CE
+.PP
+In the following examples, the initial value of \fIx\fR is:
+.PP
+.CS
+set x [list [list [list a b] [list c d]] \e
+            [list [list e f] [list g h]]]
+      \fI\(-> {{a b} {c d}} {{e f} {g h}}\fR

+.SH NAME
+lsort \- Sort the elements of a list
+.SH SYNOPSIS
+\fBlsort \fR?\fIoptions\fR? \fIlist\fR
+.BE
+.SH DESCRIPTION
+.PP
+This command sorts the elements of \fIlist\fR, returning a new
+list in sorted order.  The implementation of the \fBlsort\fR command
+uses the merge\-sort algorithm which is a stable sort that has O(n log
+n) performance characteristics.
+.PP
+By default ASCII sorting is used with the result returned in
+increasing order.  However, any of the following options may be
+specified before \fIlist\fR to control the sorting process (unique
+abbreviations are accepted):
+.TP
+\fB\-ascii\fR
+.
+Use string comparison with Unicode code-point collation order (the
+name is for backward-compatibility reasons.)  This is the default.
+.TP
+\fB\-dictionary\fR
+.
+Use dictionary-style comparison.  This is the same as \fB\-ascii\fR
+except (a) case is ignored except as a tie-breaker and (b) if two
+strings contain embedded numbers, the numbers compare as integers,
+not characters.  For example, in \fB\-dictionary\fR mode, \fBbigBoy\fR
+sorts between \fBbigbang\fR and \fBbigboy\fR, and \fBx10y\fR
+sorts between \fBx9y\fR and \fBx11y\fR.
+.TP
+\fB\-integer\fR
+.
+Convert list elements to integers and use integer comparison.
+.TP
+\fB\-real\fR
+.
+Convert list elements to floating-point values and use floating comparison.
+.TP
+\fB\-command\0\fIcommand\fR
+.
+Use \fIcommand\fR as a comparison command.
+To compare two elements, evaluate a Tcl script consisting of
+\fIcommand\fR with the two elements appended as additional
+arguments.  The script should return an integer less than,
+equal to, or greater than zero if the first element is to
+be considered less than, equal to, or greater than the second,
+respectively.
+.TP
+\fB\-increasing\fR
+.
+Sort the list in increasing order
+.PQ smallest "items first" .
+This is the default.
+.TP
+\fB\-decreasing\fR
+.
+Sort the list in decreasing order
+.PQ largest "items first" .
+.TP
+\fB\-indices\fR
+.
+Return a list of indices into \fIlist\fR in sorted order instead of
+the values themselves.
+.TP
+\fB\-index\0\fIindexList\fR
+.
+If this option is specified, each of the elements of \fIlist\fR must
+itself be a proper Tcl sublist (unless \fB\-stride\fR is used).
+Instead of sorting based on whole sublists, \fBlsort\fR will extract
+the \fIindexList\fR'th element from each sublist (as if the overall
+element and the \fIindexList\fR were passed to \fBlindex\fR) and sort
+based on the given element.
+For example,
+.RS
+.PP
+.CS
+\fBlsort\fR -integer -index 1 \e
+      {{First 24} {Second 18} {Third 30}}
+.CE
+.PP
+returns \fB{Second 18} {First 24} {Third 30}\fR,
+.PP
+'\"
+'\" This example is from the test suite!
+'\"
+.CS
+\fBlsort\fR -index end-1 \e
+        {{a 1 e i} {b 2 3 f g} {c 4 5 6 d h}}
+.CE
+.PP
+returns \fB{c 4 5 6 d h} {a 1 e i} {b 2 3 f g}\fR,
+and
+.PP
+.CS
+\fBlsort\fR -index {0 1} {
+    {{b i g} 12345}
+    {{d e m o} 34512}
+    {{c o d e} 54321}
+}
+.CE
+.PP
+returns \fB{{d e m o} 34512} {{b i g} 12345} {{c o d e} 54321}\fR
+(because \fBe\fR sorts before \fBi\fR which sorts before \fBo\fR.)
+This option is much more efficient than using \fB\-command\fR
+to achieve the same effect.
+.RE
+.TP
+\fB\-stride\0\fIstrideLength\fR
+.
+If this option is specified, the list is treated as consisting of
+groups of \fIstrideLength\fR elements and the groups are sorted by
+either their first element or, if the \fB\-index\fR option is used,
+by the element within each group given by the first index passed to
+\fB\-index\fR (which is then ignored by \fB\-index\fR). Elements
+always remain in the same position within their group.
+.RS
+.PP
+The list length must be an integer multiple of \fIstrideLength\fR, which
+in turn must be at least 2.
+.PP
+For example,
+.PP
+.CS
+\fBlsort\fR \-stride 2 {carrot 10 apple 50 banana 25}
+.CE
+.PP
+returns
+.QW "apple 50 banana 25 carrot 10" ,
+and
+.PP
+.CS
+\fBlsort\fR \-stride 2 \-index 1 \-integer {carrot 10 apple 50 banana 25}
+.CE
+.PP
+returns
+.QW "carrot 10 banana 25 apple 50" .
+.RE
+.TP
+\fB\-nocase\fR
+.
+Causes comparisons to be handled in a case-insensitive manner.  Has no
+effect if combined with the \fB\-dictionary\fR, \fB\-integer\fR, or 
+\fB\-real\fR options.
+.TP
+\fB\-unique\fR
+.
+If this option is specified, then only the last set of duplicate
+elements found in the list will be retained.  Note that duplicates are
+determined relative to the comparison used in the sort.  Thus if 
+\fB\-index 0\fR is used, \fB{1 a}\fR and \fB{1 b}\fR would be
+considered duplicates and only the second element, \fB{1 b}\fR, would
+be retained.
+.SH "NOTES"
+.PP
+The options to \fBlsort\fR only control what sort of comparison is
+used, and do not necessarily constrain what the values themselves
+actually are.  This distinction is only noticeable when the list to be
+sorted has fewer than two elements.
+.PP
+The \fBlsort\fR command is reentrant, meaning it is safe to use as
+part of the implementation of a command used in the \fB\-command\fR
+option.

+.SH "DESCRIPTION"
+.PP
+The \fBexpr\fR command handles mathematical functions of the form
+\fBsin($x)\fR or \fBatan2($y,$x)\fR by converting them to calls of the
+form \fB[tcl::mathfunc::sin [expr {$x}]]\fR or
+\fB[tcl::mathfunc::atan2 [expr {$y}] [expr {$x}]]\fR.
+A number of math functions are available by default within the
+namespace \fB::tcl::mathfunc\fR; these functions are also available
+for code apart from \fBexpr\fR, by invoking the given commands
+directly.
+.PP
+Tcl supports the following mathematical functions in expressions, all
+of which work solely with floating-point numbers unless otherwise noted:
+.DS
+.ta 3c 6c 9c
+\fBabs\fR	\fBacos\fR	\fBasin\fR	\fBatan\fR
+\fBatan2\fR	\fBbool\fR	\fBceil\fR	\fBcos\fR
+\fBcosh\fR	\fBdouble\fR	\fBentier\fR	\fBexp\fR
+\fBfloor\fR	\fBfmod\fR	\fBhypot\fR	\fBint\fR
+\fBisqrt\fR	\fBlog\fR	\fBlog10\fR	\fBmax\fR
+\fBmin\fR	\fBpow\fR	\fBrand\fR	\fBround\fR
+\fBsin\fR	\fBsinh\fR	\fBsqrt\fR	\fBsrand\fR
+\fBtan\fR	\fBtanh\fR	\fBwide\fR
+.DE
+.PP
+In addition to these predefined functions, applications may
+define additional functions by using \fBproc\fR (or any other method,
+such as \fBinterp alias\fR or \fBTcl_CreateObjCommand\fR) to define
+new commands in the \fBtcl::mathfunc\fR namespace.  In addition, an
+obsolete interface named \fBTcl_CreateMathFunc\fR() is available to
+extensions that are written in C. The latter interface is not recommended
+for new implementations.
+.SS "DETAILED DEFINITIONS"
+.TP
+\fBabs \fIarg\fR
+.
+Returns the absolute value of \fIarg\fR.  \fIArg\fR may be either
+integer or floating-point, and the result is returned in the same form.
+.TP
+\fBacos \fIarg\fR
+.
+Returns the arc cosine of \fIarg\fR, in the range [\fI0\fR,\fIpi\fR]
+radians. \fIArg\fR should be in the range [\fI\-1\fR,\fI1\fR].
+.TP
+\fBasin \fIarg\fR
+.
+Returns the arc sine of \fIarg\fR, in the range [\fI\-pi/2\fR,\fIpi/2\fR]
+radians.  \fIArg\fR should be in the range [\fI\-1\fR,\fI1\fR].
+.TP
+\fBatan \fIarg\fR
+.
+Returns the arc tangent of \fIarg\fR, in the range [\fI\-pi/2\fR,\fIpi/2\fR]
+radians.
+.TP
+\fBatan2 \fIy x\fR
+.
+Returns the arc tangent of \fIy\fR/\fIx\fR, in the range [\fI\-pi\fR,\fIpi\fR]
+radians.  \fIx\fR and \fIy\fR cannot both be 0.  If \fIx\fR is greater
+than \fI0\fR, this is equivalent to
+.QW "\fBatan \fR[\fBexpr\fR {\fIy\fB/\fIx\fR}]" .
+.TP
+\fBbool \fIarg\fR
+.
+Accepts any numeric value, or any string acceptable to
+\fBstring is boolean\fR, and returns the corresponding 
+boolean value \fB0\fR or \fB1\fR.  Non-zero numbers are true.
+Other numbers are false.  Non-numeric strings produce boolean value in
+agreement with \fBstring is true\fR and \fBstring is false\fR.
+.TP
+\fBceil \fIarg\fR
+.
+Returns the smallest integral floating-point value (i.e. with a zero
+fractional part) not less than \fIarg\fR.  The argument may be any
+numeric value.
+.TP
+\fBcos \fIarg\fR
+.
+Returns the cosine of \fIarg\fR, measured in radians.
+.TP
+\fBcosh \fIarg\fR
+.
+Returns the hyperbolic cosine of \fIarg\fR.  If the result would cause
+an overflow, an error is returned.
+.TP
+\fBdouble \fIarg\fR
+.
+The argument may be any numeric value,
+If \fIarg\fR is a floating-point value, returns \fIarg\fR, otherwise converts
+\fIarg\fR to floating-point and returns the converted value.  May return
+\fBInf\fR or \fB\-Inf\fR when the argument is a numeric value that exceeds
+the floating-point range.
+.TP
+\fBentier \fIarg\fR
+.
+The argument may be any numeric value.  The integer part of \fIarg\fR
+is determined and returned.  The integer range returned by this function
+is unlimited, unlike \fBint\fR and \fBwide\fR which
+truncate their range to fit in particular storage widths.
+.TP
+\fBexp \fIarg\fR
+.
+Returns the exponential of \fIarg\fR, defined as \fIe\fR**\fIarg\fR.
+If the result would cause an overflow, an error is returned.
+.TP
+\fBfloor \fIarg\fR
+.
+Returns the largest integral floating-point value (i.e. with a zero
+fractional part) not greater than \fIarg\fR.  The argument may be
+any numeric value.
+.TP
+\fBfmod \fIx y\fR
+.
+Returns the floating-point remainder of the division of \fIx\fR by
+\fIy\fR.  If \fIy\fR is 0, an error is returned.
+.TP
+\fBhypot \fIx y\fR
+.
+Computes the length of the hypotenuse of a right-angled triangle,
+approximately
+.QW "\fBsqrt\fR [\fBexpr\fR {\fIx\fB*\fIx\fB+\fIy\fB*\fIy\fR}]"
+except for being more numerically stable when the two arguments have
+substantially different magnitudes.
+.TP
+\fBint \fIarg\fR
+.
+The argument may be any numeric value.  The integer part of \fIarg\fR
+is determined, and then the low order bits of that integer value up
+to the machine word size are returned as an integer value.  For reference,
+the number of bytes in the machine word are stored in the \fBwordSize\fR
+element of the \fBtcl_platform\fR array.
+.TP
+\fBisqrt \fIarg\fR
+.
+Computes the integer part of the square root of \fIarg\fR.  \fIArg\fR must be
+a positive value, either an integer or a floating point number.
+Unlike \fBsqrt\fR, which is limited to the precision of a floating point
+number, \fIisqrt\fR will return a result of arbitrary precision.
+.TP
+\fBlog \fIarg\fR
+.
+Returns the natural logarithm of \fIarg\fR.  \fIArg\fR must be a
+positive value.
+.TP
+\fBlog10 \fIarg\fR
+.
+Returns the base 10 logarithm of \fIarg\fR.  \fIArg\fR must be a
+positive value.
+.TP
+\fBmax \fIarg\fB \fI...\fR
+.
+Accepts one or more numeric arguments.  Returns the one argument
+with the greatest value.
+.TP
+\fBmin \fIarg\fB \fI...\fR
+.
+Accepts one or more numeric arguments.  Returns the one argument
+with the least value.
+.TP
+\fBpow \fIx y\fR
+.
+Computes the value of \fIx\fR raised to the power \fIy\fR.  If \fIx\fR
+is negative, \fIy\fR must be an integer value.
+.TP
+\fBrand\fR
+.
+Returns a pseudo-random floating-point value in the range (\fI0\fR,\fI1\fR).  
+The generator algorithm is a simple linear congruential generator that
+is not cryptographically secure.  Each result from \fBrand\fR completely
+determines all future results from subsequent calls to \fBrand\fR, so
+\fBrand\fR should not be used to generate a sequence of secrets, such as
+one-time passwords.  The seed of the generator is initialized from the
+internal clock of the machine or may be set with the \fBsrand\fR function.
+.TP
+\fBround \fIarg\fR
+.
+If \fIarg\fR is an integer value, returns \fIarg\fR, otherwise converts
+\fIarg\fR to integer by rounding and returns the converted value.
+.TP
+\fBsin \fIarg\fR
+.
+Returns the sine of \fIarg\fR, measured in radians.
+.TP
+\fBsinh \fIarg\fR
+.
+Returns the hyperbolic sine of \fIarg\fR.  If the result would cause
+an overflow, an error is returned.
+.TP
+\fBsqrt \fIarg\fR
+.
+The argument may be any non-negative numeric value.  Returns a floating-point
+value that is the square root of \fIarg\fR.  May return \fBInf\fR when the
+argument is a numeric value that exceeds the square of the maximum value of
+the floating-point range.
+.TP
+\fBsrand \fIarg\fR
+.
+The \fIarg\fR, which must be an integer, is used to reset the seed for
+the random number generator of \fBrand\fR.  Returns the first random
+number (see \fBrand\fR) from that seed.  Each interpreter has its own seed.
+.TP
+\fBtan \fIarg\fR
+.
+Returns the tangent of \fIarg\fR, measured in radians.
+.TP
+\fBtanh \fIarg\fR
+.
+Returns the hyperbolic tangent of \fIarg\fR.
+.TP
+\fBwide \fIarg\fR
+.
+The argument may be any numeric value.  The integer part of \fIarg\fR
+is determined, and then the low order 64 bits of that integer value
+are returned as an integer value.

+.SH DESCRIPTION
+.PP
+The commands in the \fB::tcl::mathop\fR namespace implement the same set of
+operations as supported by the \fBexpr\fR command. All are exported from the
+namespace, but are not imported into any other namespace by default. Note that
+renaming, reimplementing or deleting any of the commands in the namespace does
+\fInot\fR alter the way that the \fBexpr\fR command behaves, and nor does
+defining any new commands in the \fB::tcl::mathop\fR namespace.
+.PP
+The following operator commands are supported:
+.DS
+.ta 2c 4c 6c 8c
+\fB~\fR	\fB!\fR	\fB+\fR	\fB\-\fR	\fB*\fR
+\fB/\fR	\fB%\fR	\fB**\fR	\fB&\fR	\fB|\fR
+\fB^\fR	\fB>>\fR	\fB<<\fR	\fB==\fR	\fBeq\fR
+\fB!=\fR	\fBne\fR	\fB<\fR	\fB<=\fR	\fB>\fR
+\fB>=\fR	\fBin\fR	\fBni\fR
+.DE
+.SS "MATHEMATICAL OPERATORS"
+.PP
+The behaviors of the mathematical operator commands are as follows:
+.TP
+\fB!\fR \fIboolean\fR
+.
+Returns the boolean negation of \fIboolean\fR, where \fIboolean\fR may be any
+numeric value or any other form of boolean value (i.e. it returns truth if the
+argument is falsity or zero, and falsity if the argument is truth or
+non-zero).
+.TP
+\fB+\fR ?\fInumber\fR ...?
+.
+Returns the sum of arbitrarily many arguments. Each \fInumber\fR argument may
+be any numeric value. If no arguments are given, the result will be zero (the
+summation identity).
+.TP
+\fB\-\fR \fInumber\fR ?\fInumber\fR ...?
+.
+If only a single \fInumber\fR argument is given, returns the negation of that
+numeric value. Otherwise returns the number that results when all subsequent
+numeric values are subtracted from the first one. All \fInumber\fR arguments
+must be numeric values. At least one argument must be given.
+.TP
+\fB*\fR ?\fInumber\fR ...?
+.
+Returns the product of arbitrarily many arguments. Each \fInumber\fR may be
+any numeric value. If no arguments are given, the result will be one (the
+multiplicative identity).
+.TP
+\fB/\fR \fInumber\fR ?\fInumber\fR ...?
+.
+If only a single \fInumber\fR argument is given, returns the reciprocal of that
+numeric value (i.e. the value obtained by dividing 1.0 by that value).
+Otherwise returns the number that results when the first numeric argument is
+divided by all subsequent numeric arguments. All \fInumber\fR arguments must
+be numeric values. At least one argument must be given.
+.RS
+.PP
+Note that when the leading values in the list of arguments are integers,
+integer division will be used for those initial steps (i.e. the intermediate
+results will be as if the functions \fIfloor\fR and \fIint\fR are applied to
+them, in that order). If all values in the operation are integers, the result
+will be an integer.
+.RE
+.TP
+\fB%\fR \fInumber number\fR
+.
+Returns the integral modulus (i.e., remainder) of the first argument
+with respect to the second.
+Each \fInumber\fR must have an integral value.
+Also, the sign of the result will be the same as the sign of the second
+\fInumber\fR, which must not be zero.
+.RS
+.PP
+Note that Tcl defines this operation exactly even for negative numbers, so
+that the following command returns a true value (omitting the namespace for
+clarity):
+.PP
+.CS
+\fB==\fR [\fB*\fR [\fB/\fI x y\fR] \fIy\fR] [\fB\-\fI x\fR [\fB%\fI x y\fR]]
+.CE
+.RE
+.TP
+\fB**\fR ?\fInumber\fR ...?
+.
+Returns the result of raising each value to the power of the result of
+recursively operating on the result of processing the following arguments, so
+.QW "\fB** 2 3 4\fR"
+is the same as
+.QW "\fB** 2 [** 3 4]\fR" .
+Each \fInumber\fR may be
+any numeric value, though the second number must not be fractional if the
+first is negative. If no arguments are given, the result will be one, and if
+only one argument is given, the result will be that argument. The
+result will have an integral value only when all arguments are
+integral values.
+.SS "COMPARISON OPERATORS"
+.PP
+The behaviors of the comparison operator commands (most of which operate
+preferentially on numeric arguments) are as follows:
+.TP
+\fB==\fR ?\fIarg\fR ...?
+.
+Returns whether each argument is equal to the arguments on each side of it in
+the sense of the \fBexpr\fR == operator (\fIi.e.\fR, numeric comparison if
+possible, exact string comparison otherwise). If fewer than two arguments
+are given, this operation always returns a true value.
+.TP

+\fB~\fR \fInumber\fR
+.
+Returns the bit-wise negation of \fInumber\fR. \fINumber\fR may be an integer

+.BS
+.SH NAME
+memory \- Control Tcl memory debugging capabilities
+.SH SYNOPSIS
+\fBmemory \fIoption \fR?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+The \fBmemory\fR command gives the Tcl developer control of Tcl's memory
+debugging capabilities.  The memory command has several suboptions, which are
+described below.  It is only available when Tcl has been compiled with
+memory debugging enabled (when \fBTCL_MEM_DEBUG\fR is defined at
+compile time), and after \fBTcl_InitMemory\fR has been called.
+.TP
+\fBmemory active\fR \fIfile\fR
+.
+Write a list of all currently allocated memory to the specified \fIfile\fR.
+.TP
+\fBmemory break_on_malloc\fR \fIcount\fR
+.
+After the \fIcount\fR allocations have been performed, \fBckalloc\fR
+outputs a message to this effect and that it is now attempting to enter
+the C debugger.  Tcl will then issue a \fISIGINT\fR signal against itself.
+If you are running Tcl under a C debugger, it should then enter the debugger
+command mode.
+.TP
+\fBmemory info\fR
+.
+Returns a report containing the total allocations and frees since 
+Tcl began, the current packets allocated (the current
+number of calls to \fBckalloc\fR not met by a corresponding call 
+to \fBckfree\fR), the current bytes allocated, and the maximum number
+of packets and bytes allocated.
+.TP
+\fBmemory init \fR[\fBon\fR|\fBoff\fR]
+.
+Turn on or off the pre-initialization of all allocated memory
+with bogus bytes.  Useful for detecting the use of uninitialized
+values.
+.TP
+\fBmemory objs \fIfile\fR
+.
+Causes a list of all allocated Tcl_Obj values to be written to the specified
+\fIfile\fR immediately, together with where they were allocated.  Useful for
+checking for leaks of values.
+.TP
+\fBmemory onexit\fR \fIfile\fR
+.
+Causes a list of all allocated memory to be written to the specified \fIfile\fR
+during the finalization of Tcl's memory subsystem.  Useful for checking
+that memory is properly cleaned up during process exit.
+.TP
+\fBmemory tag\fR \fIstring\fR
+.
+Each packet of memory allocated by \fBckalloc\fR can have associated
+with it a string-valued tag.  In the lists of allocated memory generated
+by \fBmemory active\fR and \fBmemory onexit\fR, the tag for each packet
+is printed along with other information about the packet.  The
+\fBmemory tag\fR command sets the tag value for subsequent calls
+to \fBckalloc\fR to be \fIstring\fR.  
+.TP
+\fBmemory trace \fR[\fBon\fR|\fBoff\fR]
+.
+Turns memory tracing on or off.  When memory tracing is on, every call
+to \fBckalloc\fR causes a line of trace information to be written to
+\fIstderr\fR, consisting of the word \fIckalloc\fR, followed by the
+address returned, the amount of memory allocated, and the C filename
+and line number of the code performing the allocation.  For example:
+.RS
+.PP
+.CS
+ckalloc 40e478 98 tclProc.c 1406
+.CE
+.PP
+Calls to \fBckfree\fR are traced in the same manner.
+.RE
+.TP
+\fBmemory trace_on_at_malloc\fR \fIcount\fR
+.
+Enable memory tracing after \fIcount\fR \fBckalloc\fRs have been performed.
+For example, if you enter \fBmemory trace_on_at_malloc 100\fR,
+after the 100th call to \fBckalloc\fR, memory trace information will begin
+being displayed for all allocations and frees.  Since there can be a lot
+of memory activity before a problem occurs, judicious use of this option
+can reduce the slowdown caused by tracing (and the amount of trace information
+produced), if you can identify a number of allocations that occur before
+the problem sets in.  The current number of memory allocations that have 
+occurred since Tcl started is printed on a guard zone failure.
+.TP
+\fBmemory validate \fR[\fBon\fR|\fBoff\fR]
+.
+Turns memory validation on or off. When memory validation is enabled,
+on every call to \fBckalloc\fR or \fBckfree\fR, the guard zones are
+checked for every piece of memory currently in existence that was
+allocated by \fBckalloc\fR.  This has a large performance impact and
+should only be used when overwrite problems are strongly suspected.
+The advantage of enabling memory validation is that a guard zone
+overwrite can be detected on the first call to \fBckalloc\fR or
+\fBckfree\fR after the overwrite occurred, rather than when the
+specific memory with the overwritten guard zone(s) is freed, which may
+occur long after the overwrite occurred.

+.BE
+.SH DESCRIPTION
+.PP
+The \fBmsgcat\fR package provides a set of functions
+that can be used to manage multi-lingual user interfaces.
+Text strings are defined in a
+.QW "message catalog"
+which is independent from the application, and
+which can be edited or localized without modifying
+the application source code.  New languages
+or locales are provided by adding a new file to
+the message catalog.
+.PP
+Use of the message catalog is optional by any application
+or package, but is encouraged if the application or package
+wishes to be enabled for multi-lingual applications.
+.SH COMMANDS
+.TP
+\fB::msgcat::mc \fIsrc-string\fR ?\fIarg arg ...\fR?
+.
+Returns a translation of \fIsrc-string\fR according to the
+user's current locale.  If additional arguments past \fIsrc-string\fR
+are given, the \fBformat\fR command is used to substitute the
+additional arguments in the translation of \fIsrc-string\fR.
+.RS
+.PP
+\fB::msgcat::mc\fR will search the messages defined
+in the current namespace for a translation of \fIsrc-string\fR; if
+none is found, it will search in the parent of the current namespace,
+and so on until it reaches the global namespace.  If no translation
+string exists, \fB::msgcat::mcunknown\fR is called and the string
+returned from \fB::msgcat::mcunknown\fR is returned.
+.PP
+\fB::msgcat::mc\fR is the main function used to localize an
+application.  Instead of using an English string directly, an
+application can pass the English string through \fB::msgcat::mc\fR and
+use the result.  If an application is written for a single language in
+this fashion, then it is easy to add support for additional languages
+later simply by defining new message catalog entries.
+.RE
+.TP
+\fB::msgcat::mcmax ?\fIsrc-string src-string ...\fR?
+.
+Given several source strings, \fB::msgcat::mcmax\fR returns the length
+of the longest translated string.  This is useful when designing
+localized GUIs, which may require that all buttons, for example, be a
+fixed width (which will be the width of the widest button).
+.TP
+\fB::msgcat::mclocale \fR?\fInewLocale\fR?
+.
+This function sets the locale to \fInewLocale\fR.  If \fInewLocale\fR
+is omitted, the current locale is returned, otherwise the current locale
+is set to \fInewLocale\fR.  msgcat stores and compares the locale in a
+case-insensitive manner, and returns locales in lowercase.
+The initial locale is determined by the locale specified in
+the user's environment.  See \fBLOCALE SPECIFICATION\fR
+below for a description of the locale string format.
+.TP
+\fB::msgcat::mcpreferences\fR
+.
+Returns an ordered list of the locales preferred by
+the user, based on the user's language specification.
+The list is ordered from most specific to least
+preference.  The list is derived from the current
+locale set in msgcat by \fB::msgcat::mclocale\fR, and
+cannot be set independently.  For example, if the
+current locale is en_US_funky, then \fB::msgcat::mcpreferences\fR
+returns \fB{en_US_funky en_US en {}}\fR.
+.TP
+\fB::msgcat::mcload \fIdirname\fR
+.
+Searches the specified directory for files that match
+the language specifications returned by \fB::msgcat::mcpreferences\fR
+(note that these are all lowercase), extended by the file extension
+.QW .msg .
+Each matching file is
+read in order, assuming a UTF-8 encoding.  The file contents are
+then evaluated as a Tcl script.  This means that Unicode characters
+may be present in the message file either directly in their UTF-8
+encoded form, or by use of the backslash-u quoting recognized by Tcl
+evaluation.  The number of message files which matched the specification
+and were loaded is returned.
+.TP
+\fB::msgcat::mcset \fIlocale src-string \fR?\fItranslate-string\fR?
+.
+Sets the translation for \fIsrc-string\fR to \fItranslate-string\fR
+in the specified \fIlocale\fR and the current namespace.  If
+\fItranslate-string\fR is not specified, \fIsrc-string\fR is used
+for both.  The function returns \fItranslate-string\fR.
+.TP
+\fB::msgcat::mcmset \fIlocale src-trans-list\fR
+.
+Sets the translation for multiple source strings in
+\fIsrc-trans-list\fR in the specified \fIlocale\fR and the current
+namespace.
+\fIsrc-trans-list\fR must have an even number of elements and is in
+the form {\fIsrc-string translate-string\fR ?\fIsrc-string
+translate-string ...\fR?} \fB::msgcat::mcmset\fR can be significantly
+faster than multiple invocations of \fB::msgcat::mcset\fR. The function
+returns the number of translations set.
+.TP
+\fB::msgcat::mcflset \fIsrc-string \fR?\fItranslate-string\fR?
+.VS "TIP 404"
+Sets the translation for \fIsrc-string\fR to \fItranslate-string\fR in the
+current namespace for the locale implied by the name of the message catalog
+being loaded via \fB::msgcat::mcload\fR.  If \fItranslate-string\fR is not
+specified, \fIsrc-string\fR is used for both.  The function returns
+\fItranslate-string\fR.
+.VE "TIP 404"
+.TP
+\fB::msgcat::mcflmset \fIsrc-trans-list\fR
+.VS "TIP 404"
+Sets the translation for multiple source strings in \fIsrc-trans-list\fR in
+the current namespace for the locale implied by the name of the message
+catalog being loaded via \fB::msgcat::mcload\fR. \fIsrc-trans-list\fR must
+have an even number of elements and is in the form {\fIsrc-string
+translate-string\fR ?\fIsrc-string translate-string ...\fR?}
+\fB::msgcat::mcflmset\fR can be significantly faster than multiple invocations
+of \fB::msgcat::mcflset\fR. The function returns the number of translations set.
+.VE "TIP 404"
+.TP
+\fB::msgcat::mcunknown \fIlocale src-string\fR
+.
+This routine is called by \fB::msgcat::mc\fR in the case when
+a translation for \fIsrc-string\fR is not defined in the
+current locale.  The default action is to return
+\fIsrc-string\fR.  This procedure can be redefined by the
+application, for example to log error messages for each unknown
+string.  The \fB::msgcat::mcunknown\fR procedure is invoked at the
+same stack context as the call to \fB::msgcat::mc\fR.  The return value
+of \fB::msgcat::mcunknown\fR is used as the return value for the call
+to \fB::msgcat::mc\fR.  
+.SH "LOCALE SPECIFICATION"
+.PP
+The locale is specified to \fBmsgcat\fR by a locale string
+passed to \fB::msgcat::mclocale\fR.
+The locale string consists of
+a language code, an optional country code, and an optional
+system-specific code, each separated by
+.QW _ .
+The country and language
+codes are specified in standards ISO-639 and ISO-3166.
+For example, the locale
+.QW en
+specifies English and
+.QW en_US
+specifies U.S. English.
+.PP
+When the msgcat package is first loaded, the locale is initialized
+according to the user's environment.  The variables \fBenv(LC_ALL)\fR,
+\fBenv(LC_MESSAGES)\fR, and \fBenv(LANG)\fR are examined in order.
+The first of them to have a non-empty value is used to determine the
+initial locale.  The value is parsed according to the XPG4 pattern
+.PP
+.CS
+language[_country][.codeset][@modifier]
+.CE
+.PP
+to extract its parts.  The initial locale is then set by calling
+\fB::msgcat::mclocale\fR with the argument 
+.PP
+.CS
+language[_country][_modifier]
+.CE
+.PP
+On Windows and Cygwin, if none of those environment variables is set,
+msgcat will attempt to extract locale information from the registry.
+From Windows Vista on, the RFC4747 locale name "lang-script-country-options"
+is transformed to the locale as "lang_country_script" (Example:
+sr-Latn-CS -> sr_cs_latin). For Windows XP, the language id is
+transformed analoguously (Example: 0c1a -> sr_yu_cyrillic).
+If all these attempts to discover an initial locale from the user's
+environment fail, msgcat defaults to an initial locale of
+.QW C .
+.PP
+When a locale is specified by the user, a
+.QW "best match"
+search is performed during string translation.  For example, if a user
+specifies
+en_GB_Funky, the locales
+.QW en_GB_Funky ,
+.QW en_GB ,
+.QW en
+and
+.MT
+(the empty string)
+are searched in order until a matching translation
+string is found.  If no translation string is available, then
+\fB::msgcat::mcunknown\fR is called.
+.SH "NAMESPACES AND MESSAGE CATALOGS"
+.PP
+Strings stored in the message catalog are stored relative
+to the namespace from which they were added.  This allows
+multiple packages to use the same strings without fear
+of collisions with other packages.  It also allows the
+source string to be shorter and less prone to typographical
+error.
+.PP
+For example, executing the code
+.PP
+.CS
+\fB::msgcat::mcset\fR en hello "hello from ::"
+namespace eval foo {
+    \fB::msgcat::mcset\fR en hello "hello from ::foo"
+}
+puts [\fB::msgcat::mc\fR hello]
+namespace eval foo {puts [\fB::msgcat::mc\fR hello]}
+.CE
+.PP
+will print
+.PP
+.CS
+hello from ::
+hello from ::foo
+.CE
+.PP
+When searching for a translation of a message, the
+message catalog will search first the current namespace,
+then the parent of the current namespace, and so on until
+the global namespace is reached.  This allows child namespaces to
+.QW inherit
+messages from their parent namespace.
+.PP
+For example, executing (in the
+.QW en
+locale) the code
+.PP
+.CS
+\fB::msgcat::mcset\fR en m1 ":: message1"
+\fB::msgcat::mcset\fR en m2 ":: message2"
+\fB::msgcat::mcset\fR en m3 ":: message3"
+namespace eval ::foo {
+    \fB::msgcat::mcset\fR en m2 "::foo message2"
+    \fB::msgcat::mcset\fR en m3 "::foo message3"
+}
+namespace eval ::foo::bar {
+    \fB::msgcat::mcset\fR en m3 "::foo::bar message3"
+}
+namespace import \fB::msgcat::mc\fR
+puts "[\fBmc\fR m1]; [\fBmc\fR m2]; [\fBmc\fR m3]"
+namespace eval ::foo {puts "[\fBmc\fR m1]; [\fBmc\fR m2]; [\fBmc\fR m3]"}
+namespace eval ::foo::bar {puts "[\fBmc\fR m1]; [\fBmc\fR m2]; [\fBmc\fR m3]"}
+.CE
+.PP
+will print
+.PP
+.CS
+:: message1; :: message2; :: message3
+:: message1; ::foo message2; ::foo message3
+:: message1; ::foo message2; ::foo::bar message3
+.CE
+.SH "LOCATION AND FORMAT OF MESSAGE FILES"
+.PP
+Message files can be located in any directory, subject
+to the following conditions:
+.IP [1]
+All message files for a package are in the same directory.
+.IP [2]
+The message file name is a msgcat locale specifier (all lowercase) followed by
+.QW .msg .
+For example:
+.PP
+.CS
+es.msg    \(em spanish
+en_gb.msg \(em United Kingdom English
+.CE
+.PP
+\fIException:\fR The message file for the root locale
+.MT
+is called
+.QW \fBROOT.msg\fR .
+This exception is made so as not to
+cause peculiar behavior, such as marking the message file as
+.QW hidden
+on Unix file systems.
+.IP [3]
+The file contains a series of calls to \fBmcflset\fR and
+\fBmcflmset\fR, setting the necessary translation strings
+for the language, likely enclosed in a \fBnamespace eval\fR
+so that all source strings are tied to the namespace of
+the package. For example, a short \fBes.msg\fR might contain:
+.PP
+.CS
+namespace eval ::mypackage {
+    \fB::msgcat::mcflset\fR "Free Beer!" "Cerveza Gracias!"
+}
+.CE
+.SH "RECOMMENDED MESSAGE SETUP FOR PACKAGES"
+.PP
+If a package is installed into a subdirectory of the
+\fBtcl_pkgPath\fR and loaded via \fBpackage require\fR, the
+following procedure is recommended.
+.IP [1]
+During package installation, create a subdirectory
+\fBmsgs\fR under your package directory.
+.IP [2]
+Copy your *.msg files into that directory.
+.IP [3]
+Add the following command to your package initialization script:
+.PP
+.CS
+# load language files, stored in msgs subdirectory
+\fB::msgcat::mcload\fR [file join [file dirname [info script]] msgs]
+.CE
+.SH "POSITIONAL CODES FOR FORMAT AND SCAN COMMANDS"
+.PP
+It is possible that a message string used as an argument
+to \fBformat\fR might have positionally dependent parameters that
+might need to be repositioned.  For example, it might be
+syntactically desirable to rearrange the sentence structure
+while translating.
+.PP
+.CS
+format "We produced %d units in location %s" $num $city
+format "In location %s we produced %d units" $city $num
+.CE
+.PP
+This can be handled by using the positional
+parameters:
+.PP
+.CS
+format "We produced %1\e$d units in location %2\e$s" $num $city
+format "In location %2\e$s we produced %1\e$d units" $num $city
+.CE
+.PP
+Similarly, positional parameters can be used with \fBscan\fR to
+extract values from internationalized strings. Note that it is not
+necessary to pass the output of \fB::msgcat::mc\fR to \fBformat\fR
+directly; by passing the values to substitute in as arguments, the
+formatting substitution is done directly.
+.PP
+.CS
+\fBmsgcat::mc\fR {Produced %1$d at %2$s} $num $city

+.BE
+.SH DESCRIPTION
+.PP
+The \fBmy\fR command is used to allow methods of objects to invoke any method
+of the object (or its class). In particular, the set of valid values for
+\fImethodName\fR is the set of all methods supported by an object and its
+superclasses, including those that are not exported. The object upon which the
+method is invoked is always the one that is the current context of the method
+(i.e. the object that is returned by \fBself object\fR) from which the
+\fBmy\fR command is invoked.
+.PP
+Each object has its own \fBmy\fR command, contained in its instance namespace.
+.SH EXAMPLES
+.PP
+This example shows basic use of \fBmy\fR to use the \fBvariables\fR method of
+the \fBoo::object\fR class, which is not publicly visible by default:
+.PP
+.CS
+oo::class create c {
+    method count {} {
+        \fBmy\fR variable counter
+        print [incr counter]
+    }

+.SH NAME
+namespace \- create and manipulate contexts for commands and variables
+.SH SYNOPSIS
+\fBnamespace \fR?\fIsubcommand\fR? ?\fIarg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+The \fBnamespace\fR command lets you create, access, and destroy
+separate contexts for commands and variables.
+See the section \fBWHAT IS A NAMESPACE?\fR below
+for a brief overview of namespaces.
+The legal values of \fIsubcommand\fR are listed below.
+Note that you can abbreviate the \fIsubcommand\fRs.
+.TP
+\fBnamespace children \fR?\fInamespace\fR? ?\fIpattern\fR?
+.
+Returns a list of all child namespaces that belong to the
+namespace \fInamespace\fR.
+If \fInamespace\fR is not specified,
+then the children are returned for the current namespace.
+This command returns fully-qualified names,
+which start with a double colon (\fB::\fR).
+If the optional \fIpattern\fR is given,
+then this command returns only the names that match the glob-style pattern.
+The actual pattern used is determined as follows:
+a pattern that starts with double colon (\fB::\fR) is used directly,
+otherwise the namespace \fInamespace\fR
+(or the fully-qualified name of the current namespace)
+is prepended onto the pattern.
+.TP
+\fBnamespace code \fIscript\fR
+.
+Captures the current namespace context for later execution
+of the script \fIscript\fR.
+It returns a new script in which \fIscript\fR has been wrapped
+in a \fBnamespace inscope\fR command.
+The new script has two important properties.
+First, it can be evaluated in any namespace and will cause
+\fIscript\fR to be evaluated in the current namespace
+(the one where the \fBnamespace code\fR command was invoked).
+Second, additional arguments can be appended to the resulting script
+and they will be passed to \fIscript\fR as additional arguments.
+For example, suppose the command
+\fBset script [namespace code {foo bar}]\fR
+is invoked in namespace \fB::a::b\fR.
+Then \fBeval $script [list x y]\fR
+can be executed in any namespace (assuming the value of
+\fBscript\fR has been passed in properly)
+and will have the same effect as the command
+\fB::namespace eval ::a::b {foo bar x y}\fR.
+This command is needed because
+extensions like Tk normally execute callback scripts
+in the global namespace.
+A scoped command captures a command together with its namespace context
+in a way that allows it to be executed properly later.
+See the section \fBSCOPED SCRIPTS\fR for some examples
+of how this is used to create callback scripts.
+.TP
+\fBnamespace current\fR
+.
+Returns the fully-qualified name for the current namespace.
+The actual name of the global namespace is
+.MT
+(i.e., an empty string),
+but this command returns \fB::\fR for the global namespace
+as a convenience to programmers.
+.TP
+\fBnamespace delete \fR?\fInamespace namespace ...\fR?
+.
+Each namespace \fInamespace\fR is deleted
+and all variables, procedures, and child namespaces
+contained in the namespace are deleted.
+If a procedure is currently executing inside the namespace,
+the namespace will be kept alive until the procedure returns;
+however, the namespace is marked to prevent other code from
+looking it up by name.
+If a namespace does not exist, this command returns an error.
+If no namespace names are given, this command does nothing.
+.TP
+\fBnamespace ensemble\fR \fIsubcommand\fR ?\fIarg ...\fR?
+.
+Creates and manipulates a command that is formed out of an ensemble of
+subcommands.  See the section \fBENSEMBLES\fR below for further
+details.
+.TP
+\fBnamespace eval\fR \fInamespace arg\fR ?\fIarg ...\fR?
+.
+Activates a namespace called \fInamespace\fR and evaluates some code
+in that context.
+If the namespace does not already exist, it is created.
+If more than one \fIarg\fR argument is specified,
+the arguments are concatenated together with a space between each one
+in the same fashion as the \fBeval\fR command,
+and the result is evaluated.
+.RS
+.PP
+If \fInamespace\fR has leading namespace qualifiers
+and any leading namespaces do not exist,
+they are automatically created.
+.RE
+.TP
+\fBnamespace exists\fR \fInamespace\fR
+.
+Returns \fB1\fR if \fInamespace\fR is a valid namespace in the current
+context, returns \fB0\fR otherwise.
+.TP
+\fBnamespace export \fR?\fB\-clear\fR? ?\fIpattern pattern ...\fR?
+.
+Specifies which commands are exported from a namespace.
+The exported commands are those that can be later imported
+into another namespace using a \fBnamespace import\fR command.
+Both commands defined in a namespace and
+commands the namespace has previously imported
+can be exported by a namespace.
+The commands do not have to be defined
+at the time the \fBnamespace export\fR command is executed.
+Each \fIpattern\fR may contain glob-style special characters,
+but it may not include any namespace qualifiers.
+That is, the pattern can only specify commands
+in the current (exporting) namespace.
+Each \fIpattern\fR is appended onto the namespace's list of export patterns.
+If the \fB\-clear\fR flag is given,
+the namespace's export pattern list is reset to empty before any
+\fIpattern\fR arguments are appended.
+If no \fIpattern\fRs are given and the \fB\-clear\fR flag is not given,
+this command returns the namespace's current export list.
+.TP
+\fBnamespace forget \fR?\fIpattern pattern ...\fR?
+.
+Removes previously imported commands from a namespace.
+Each \fIpattern\fR is a simple or qualified name such as
+\fBx\fR, \fBfoo::x\fR or \fBa::b::p*\fR.
+Qualified names contain double colons (\fB::\fR) and qualify a name
+with the name of one or more namespaces.
+Each
+.QW "qualified pattern"
+is qualified with the name of an exporting namespace
+and may have glob-style special characters in the command name
+at the end of the qualified name.
+Glob characters may not appear in a namespace name.
+For each
+.QW "simple pattern"
+this command deletes the matching commands of the
+current namespace that were imported from a different namespace.
+For
+.QW "qualified patterns" ,
+this command first finds the matching exported commands.
+It then checks whether any of those commands
+were previously imported by the current namespace.
+If so, this command deletes the corresponding imported commands.
+In effect, this un-does the action of a \fBnamespace import\fR command.
+.TP
+\fBnamespace import \fR?\fB\-force\fR? ?\fIpattern\fR \fIpattern ...\fR?
+.
+Imports commands into a namespace, or queries the set of imported
+commands in a namespace.  When no arguments are present,
+\fBnamespace import\fR returns the list of commands in
+the current namespace that have been imported from other
+namespaces.  The commands in the returned list are in
+the format of simple names, with no namespace qualifiers at all.
+This format is suitable for composition with \fBnamespace forget\fR
+(see \fBEXAMPLES\fR below).
+.RS
+.PP
+When \fIpattern\fR arguments are present,
+each \fIpattern\fR is a qualified name like
+\fBfoo::x\fR or \fBa::p*\fR.
+That is, it includes the name of an exporting namespace
+and may have glob-style special characters in the command name
+at the end of the qualified name.
+Glob characters may not appear in a namespace name.
+When the namespace name is not fully qualified (i.e., does not start
+with a namespace separator) it is resolved as a namespace name in the
+way described in the \fBNAME RESOLUTION\fR section; it is an error if
+no namespace with that name can be found.
+.PP
+All the commands that match a \fIpattern\fR string
+and which are currently exported from their namespace
+are added to the current namespace.
+This is done by creating a new command in the current namespace
+that points to the exported command in its original namespace;
+when the new imported command is called, it invokes the exported command.
+This command normally returns an error
+if an imported command conflicts with an existing command.
+However, if the \fB\-force\fR option is given,
+imported commands will silently replace existing commands.
+The \fBnamespace import\fR command has snapshot semantics:
+that is, only requested commands that are currently defined
+in the exporting namespace are imported.
+In other words, you can import only the commands that are in a namespace
+at the time when the \fBnamespace import\fR command is executed.
+If another command is defined and exported in this namespace later on,
+it will not be imported.
+.RE
+.TP
+\fBnamespace inscope\fR \fInamespace\fR \fIscript\fR ?\fIarg ...\fR?
+.
+Executes a script in the context of the specified \fInamespace\fR.
+This command is not expected to be used directly by programmers;
+calls to it are generated implicitly when applications
+use \fBnamespace code\fR commands to create callback scripts
+that the applications then register with, e.g., Tk widgets.
+The \fBnamespace inscope\fR command is much like the \fBnamespace eval\fR
+command except that the \fInamespace\fR must already exist,
+and \fBnamespace inscope\fR appends additional \fIarg\fRs
+as proper list elements.
+.RS
+.PP
+.CS
+\fBnamespace inscope ::foo $script $x $y $z\fR
+.CE
+.PP
+is equivalent to
+.PP
+.CS
+\fBnamespace eval ::foo [concat $script [list $x $y $z]]\fR
+.CE
+.PP
+thus additional arguments will not undergo a second round of substitution,
+as is the case with \fBnamespace eval\fR.
+.RE
+.TP
+\fBnamespace origin \fIcommand\fR
+.
+Returns the fully-qualified name of the original command
+to which the imported command \fIcommand\fR refers.
+When a command is imported into a namespace,
+a new command is created in that namespace
+that points to the actual command in the exporting namespace.
+If a command is imported into a sequence of namespaces
+\fIa, b,...,n\fR where each successive namespace
+just imports the command from the previous namespace,
+this command returns the fully-qualified name of the original command
+in the first namespace, \fIa\fR.
+If \fIcommand\fR does not refer to an imported command,
+the command's own fully-qualified name is returned.
+.TP
+\fBnamespace parent\fR ?\fInamespace\fR?
+.
+Returns the fully-qualified name of the parent namespace
+for namespace \fInamespace\fR.
+If \fInamespace\fR is not specified,
+the fully-qualified name of the current namespace's parent is returned.
+.TP
+\fBnamespace path\fR ?\fInamespaceList\fR?
+.
+Returns the command resolution path of the current namespace. If
+\fInamespaceList\fR is specified as a list of named namespaces, the
+current namespace's command resolution path is set to those namespaces
+and returns the empty list. The default command resolution path is
+always empty. See the section \fBNAME RESOLUTION\fR below for an
+explanation of the rules regarding name resolution.
+.TP
+\fBnamespace qualifiers\fR \fIstring\fR
+.
+Returns any leading namespace qualifiers for \fIstring\fR.
+Qualifiers are namespace names separated by double colons (\fB::\fR).
+For the \fIstring\fR \fB::foo::bar::x\fR,
+this command returns \fB::foo::bar\fR,
+and for \fB::\fR it returns an empty string.
+This command is the complement of the \fBnamespace tail\fR command.
+Note that it does not check whether the
+namespace names are, in fact,
+the names of currently defined namespaces.
+.TP
+\fBnamespace tail\fR \fIstring\fR
+.
+Returns the simple name at the end of a qualified string.
+Qualifiers are namespace names separated by double colons (\fB::\fR).
+For the \fIstring\fR \fB::foo::bar::x\fR,
+this command returns \fBx\fR,
+and for \fB::\fR it returns an empty string.
+This command is the complement of the \fBnamespace qualifiers\fR command.
+It does not check whether the namespace names are, in fact,
+the names of currently defined namespaces.
+.TP
+\fBnamespace upvar\fR \fInamespace\fR ?\fIotherVar myVar \fR...
+.
+This command arranges for zero or more local variables in the current
+procedure to refer to variables in \fInamespace\fR. The namespace name is
+resolved as described in section \fBNAME RESOLUTION\fR.
+The command
+\fBnamespace upvar $ns a b\fR has the same behaviour as
+\fBupvar 0 ${ns}::a b\fR, with the sole exception of the resolution rules
+used for qualified namespace or variable names.
+\fBnamespace upvar\fR returns an empty string.
+.TP
+\fBnamespace unknown\fR ?\fIscript\fR?
+.
+Sets or returns the unknown command handler for the current namespace.
+The handler is invoked when a command called from within the namespace
+cannot be found in the current namespace, the namespace's path nor in
+the global namespace. 
+The \fIscript\fR argument, if given, should be a well
+formed list representing a command name and optional arguments. When
+the handler is invoked, the full invocation line will be appended to the
+script and the result evaluated in the context of the namespace. The
+default handler for all namespaces is \fB::unknown\fR. If no argument
+is given, it returns the handler for the current namespace.
+.TP
+\fBnamespace which\fR ?\fB\-command\fR? ?\fB\-variable\fR? \fIname\fR
+.
+Looks up \fIname\fR as either a command or variable
+and returns its fully-qualified name.
+For example, if \fIname\fR does not exist in the current namespace
+but does exist in the global namespace,
+this command returns a fully-qualified name in the global namespace.
+If the command or variable does not exist,
+this command returns an empty string.  If the variable has been
+created but not defined, such as with the \fBvariable\fR command
+or through a \fBtrace\fR on the variable, this command will return the
+fully-qualified name of the variable.
+If no flag is given, \fIname\fR is treated as a command name.
+See the section \fBNAME RESOLUTION\fR below for an explanation of
+the rules regarding name resolution.
+.SH "WHAT IS A NAMESPACE?"
+.PP
+A namespace is a collection of commands and variables.
+It encapsulates the commands and variables to ensure that they
+will not interfere with the commands and variables of other namespaces.
+Tcl has always had one such collection,
+which we refer to as the \fIglobal namespace\fR.
+The global namespace holds all global variables and commands.
+The \fBnamespace eval\fR command lets you create new namespaces.
+For example,
+.PP
+.CS
+\fBnamespace eval\fR Counter {
+    \fBnamespace export\fR bump
+    variable num 0
+
+    proc bump {} {
+        variable num
+        incr num
+    }
+}
+.CE
+.PP
+creates a new namespace containing the variable \fBnum\fR and
+the procedure \fBbump\fR.
+The commands and variables in this namespace are separate from
+other commands and variables in the same program.
+If there is a command named \fBbump\fR in the global namespace,
+for example, it will be different from the command \fBbump\fR
+in the \fBCounter\fR namespace.
+.PP
+Namespace variables resemble global variables in Tcl.
+They exist outside of the procedures in a namespace
+but can be accessed in a procedure via the \fBvariable\fR command,
+as shown in the example above.
+.PP
+Namespaces are dynamic.
+You can add and delete commands and variables at any time,
+so you can build up the contents of a
+namespace over time using a series of \fBnamespace eval\fR commands.
+For example, the following series of commands has the same effect
+as the namespace definition shown above:
+.PP
+.CS
+\fBnamespace eval\fR Counter {
+    variable num 0
+    proc bump {} {
+        variable num
+        return [incr num]
+    }
+}
+\fBnamespace eval\fR Counter {
+    proc test {args} {
+        return $args
+    }
+}
+\fBnamespace eval\fR Counter {
+     rename test ""
+}
+.CE
+.PP
+Note that the \fBtest\fR procedure is added to the \fBCounter\fR namespace,
+and later removed via the \fBrename\fR command.
+.PP
+Namespaces can have other namespaces within them,
+so they nest hierarchically.
+A nested namespace is encapsulated inside its parent namespace
+and can not interfere with other namespaces.
+.SH "QUALIFIED NAMES"
+.PP
+Each namespace has a textual name such as
+\fBhistory\fR or \fB::safe::interp\fR.
+Since namespaces may nest,
+qualified names are used to refer to
+commands, variables, and child namespaces contained inside namespaces.
+Qualified names are similar to the hierarchical path names for
+Unix files or Tk widgets,
+except that \fB::\fR is used as the separator
+instead of \fB/\fR or \fB.\fR.
+The topmost or global namespace has the name
+.MT
+(i.e., an empty string), although \fB::\fR is a synonym.
+As an example, the name \fB::safe::interp::create\fR
+refers to the command \fBcreate\fR in the namespace \fBinterp\fR
+that is a child of namespace \fB::safe\fR,
+which in turn is a child of the global namespace, \fB::\fR.
+.PP
+If you want to access commands and variables from another namespace,
+you must use some extra syntax.
+Names must be qualified by the namespace that contains them.
+From the global namespace,
+we might access the \fBCounter\fR procedures like this:
+.PP
+.CS
+Counter::bump 5
+Counter::Reset
+.CE
+.PP
+We could access the current count like this:
+.PP
+.CS
+puts "count = $Counter::num"
+.CE
+.PP
+When one namespace contains another, you may need more than one
+qualifier to reach its elements.
+If we had a namespace \fBFoo\fR that contained the namespace \fBCounter\fR,
+you could invoke its \fBbump\fR procedure
+from the global namespace like this:
+.PP
+.CS
+Foo::Counter::bump 3
+.CE
+.PP
+You can also use qualified names when you create and rename commands.
+For example, you could add a procedure to the \fBFoo\fR
+namespace like this:
+.PP
+.CS
+proc Foo::Test {args} {return $args}
+.CE
+.PP
+And you could move the same procedure to another namespace like this:
+.PP
+.CS
+rename Foo::Test Bar::Test
+.CE
+.PP
+There are a few remaining points about qualified names
+that we should cover.
+Namespaces have nonempty names except for the global namespace.
+\fB::\fR is disallowed in simple command, variable, and namespace names
+except as a namespace separator.
+Extra colons in any separator part of a qualified name are ignored;
+i.e. two or more colons are treated as a namespace separator.
+A trailing \fB::\fR in a qualified variable or command name
+refers to the variable or command named {}.
+However, a trailing \fB::\fR in a qualified namespace name is ignored.
+.SH "NAME RESOLUTION"
+.PP
+In general, all Tcl commands that take variable and command names
+support qualified names.
+This means you can give qualified names to such commands as
+\fBset\fR, \fBproc\fR, \fBrename\fR, and \fBinterp alias\fR.
+If you provide a fully-qualified name that starts with a \fB::\fR,
+there is no question about what command, variable, or namespace
+you mean.
+However, if the name does not start with a \fB::\fR
+(i.e., is \fIrelative\fR),
+Tcl follows basic rules for looking it up:
+.IP \(bu
+\fBVariable names\fR are always resolved by looking first in the current
+namespace, and then in the global namespace.
+.IP \(bu
+\fBCommand names\fR are always resolved by looking in the current namespace
+first. If not found there, they are searched for in every namespace on the
+current namespace's command path (which is empty by default). If not found
+there, command names are looked up in the global namespace (or, failing that,
+are processed by the appropriate \fBnamespace unknown\fR handler.)
+.IP \(bu
+\fBNamespace names\fR are always resolved by looking in only the current
+namespace.
+.PP
+In the following example,
+.PP
+.CS
+set traceLevel 0
+\fBnamespace eval\fR Debug {
+    printTrace $traceLevel
+}
+.CE
+.PP
+Tcl looks for \fBtraceLevel\fR in the namespace \fBDebug\fR
+and then in the global namespace.
+It looks up the command \fBprintTrace\fR in the same way.
+If a variable or command name is not found in either context,
+the name is undefined.
+To make this point absolutely clear, consider the following example:
+.PP
+.CS
+set traceLevel 0
+\fBnamespace eval\fR Foo {
+    variable traceLevel 3
+
+    \fBnamespace eval\fR Debug {
+        printTrace $traceLevel
+    }
+}
+.CE
+.PP
+Here Tcl looks for \fBtraceLevel\fR first in the namespace \fBFoo::Debug\fR.
+Since it is not found there, Tcl then looks for it
+in the global namespace.
+The variable \fBFoo::traceLevel\fR is completely ignored
+during the name resolution process.
+.PP
+You can use the \fBnamespace which\fR command to clear up any question
+about name resolution.
+For example, the command:
+.PP
+.CS
+\fBnamespace eval\fR Foo::Debug {\fBnamespace which\fR \-variable traceLevel}
+.CE
+.PP
+returns \fB::traceLevel\fR.
+On the other hand, the command,
+.PP
+.CS
+\fBnamespace eval\fR Foo {\fBnamespace which\fR \-variable traceLevel}
+.CE
+.PP
+returns \fB::Foo::traceLevel\fR.
+.PP
+As mentioned above,
+namespace names are looked up differently
+than the names of variables and commands.
+Namespace names are always resolved in the current namespace.
+This means, for example,
+that a \fBnamespace eval\fR command that creates a new namespace
+always creates a child of the current namespace
+unless the new namespace name begins with \fB::\fR.
+.PP
+Tcl has no access control to limit what variables, commands,
+or namespaces you can reference.
+If you provide a qualified name that resolves to an element
+by the name resolution rule above,
+you can access the element.
+.PP
+You can access a namespace variable
+from a procedure in the same namespace
+by using the \fBvariable\fR command.
+Much like the \fBglobal\fR command,
+this creates a local link to the namespace variable.
+If necessary, it also creates the variable in the current namespace
+and initializes it.
+Note that the \fBglobal\fR command only creates links
+to variables in the global namespace.
+It is not necessary to use a \fBvariable\fR command
+if you always refer to the namespace variable using an
+appropriate qualified name.
+.SH "IMPORTING COMMANDS"
+.PP
+Namespaces are often used to represent libraries.
+Some library commands are used so frequently
+that it is a nuisance to type their qualified names.
+For example, suppose that all of the commands in a package
+like BLT are contained in a namespace called \fBBlt\fR.
+Then you might access these commands like this:
+.PP
+.CS
+Blt::graph .g \-background red
+Blt::table . .g 0,0
+.CE
+.PP
+If you use the \fBgraph\fR and \fBtable\fR commands frequently,
+you may want to access them without the \fBBlt::\fR prefix.
+You can do this by importing the commands into the current namespace,
+like this:
+.PP
+.CS
+\fBnamespace import\fR Blt::*
+.CE
+.PP
+This adds all exported commands from the \fBBlt\fR namespace
+into the current namespace context, so you can write code like this:
+.PP
+.CS
+graph .g \-background red
+table . .g 0,0
+.CE
+.PP
+The \fBnamespace import\fR command only imports commands
+from a namespace that that namespace exported
+with a \fBnamespace export\fR command.
+.PP
+Importing \fIevery\fR command from a namespace is generally
+a bad idea since you do not know what you will get.
+It is better to import just the specific commands you need.
+For example, the command
+.PP
+.CS
+\fBnamespace import\fR Blt::graph Blt::table
+.CE
+.PP
+imports only the \fBgraph\fR and \fBtable\fR commands into the
+current context.
+.PP
+If you try to import a command that already exists, you will get an
+error.  This prevents you from importing the same command from two
+different packages.  But from time to time (perhaps when debugging),
+you may want to get around this restriction.  You may want to
+reissue the \fBnamespace import\fR command to pick up new commands
+that have appeared in a namespace.  In that case, you can use the
+\fB\-force\fR option, and existing commands will be silently overwritten:
+.PP
+.CS
+\fBnamespace import\fR \-force Blt::graph Blt::table
+.CE
+.PP
+If for some reason, you want to stop using the imported commands,
+you can remove them with a \fBnamespace forget\fR command, like this:
+.PP
+.CS
+\fBnamespace forget\fR Blt::*
+.CE
+.PP
+This searches the current namespace for any commands imported from \fBBlt\fR.
+If it finds any, it removes them.  Otherwise, it does nothing.
+After this, the \fBBlt\fR commands must be accessed with the \fBBlt::\fR
+prefix.
+.PP
+When you delete a command from the exporting namespace like this:
+.PP
+.CS
+rename Blt::graph ""
+.CE
+.PP
+the command is automatically removed from all namespaces that import it.
+.SH "EXPORTING COMMANDS"
+You can export commands from a namespace like this:
+.PP
+.CS
+\fBnamespace eval\fR Counter {
+    \fBnamespace export\fR bump reset
+    variable Num 0
+    variable Max 100
+
+    proc bump {{by 1}} {
+        variable Num
+        incr Num $by
+        Check
+        return $Num
+    }
+    proc reset {} {
+        variable Num
+        set Num 0
+    }
+    proc Check {} {
+        variable Num
+        variable Max
+        if {$Num > $Max} {
+            error "too high!"
+        }
+    }
+}
+.CE
+.PP
+The procedures \fBbump\fR and \fBreset\fR are exported,
+so they are included when you import from the \fBCounter\fR namespace,
+like this:
+.PP
+.CS
+\fBnamespace import\fR Counter::*
+.CE
+.PP
+However, the \fBCheck\fR procedure is not exported,
+so it is ignored by the import operation.
+.PP
+The \fBnamespace import\fR command only imports commands
+that were declared as exported by their namespace.
+The \fBnamespace export\fR command specifies what commands
+may be imported by other namespaces.
+If a \fBnamespace import\fR command specifies a command
+that is not exported, the command is not imported.
+.SH "SCOPED SCRIPTS"
+.PP
+The \fBnamespace code\fR command is the means by which a script may be
+packaged for evaluation in a namespace other than the one in which it
+was created.  It is used most often to create event handlers, Tk bindings,
+and traces for evaluation in the global context.  For instance, the following
+code indicates how to direct a variable \fBtrace\fR callback into the current
+namespace:
+.PP
+.CS
+\fBnamespace eval\fR a {
+    variable b
+    proc theTraceCallback { n1 n2 op } {
+        upvar 1 $n1 var
+        puts "the value of $n1 has changed to $var"
+        return
+    }
+    trace add variable b write [\fBnamespace code\fR theTraceCallback]
+}
+set a::b c
+.CE
+.PP
+When executed, it prints the message:
+.PP
+.CS
+the value of a::b has changed to c
+.CE
+.SH ENSEMBLES
+.PP
+The \fBnamespace ensemble\fR is used to create and manipulate ensemble
+commands, which are commands formed by grouping subcommands together.
+The commands typically come from the current namespace when the
+ensemble was created, though this is configurable.  Note that there
+may be any number of ensembles associated with any namespace
+(including none, which is true of all namespaces by default), though
+all the ensembles associated with a namespace are deleted when that
+namespace is deleted.  The link between an ensemble command and its
+namespace is maintained however the ensemble is renamed.
+.PP
+Three subcommands of the \fBnamespace ensemble\fR command are defined:
+.TP
+\fBnamespace ensemble create\fR ?\fIoption value ...\fR?
+.
+Creates a new ensemble command linked to the current namespace,
+returning the fully qualified name of the command created.  The
+arguments to \fBnamespace ensemble create\fR allow the configuration
+of the command as if with the \fBnamespace ensemble configure\fR
+command.  If not overridden with the \fB\-command\fR option, this
+command creates an ensemble with exactly the same name as the linked
+namespace.  See the section \fBENSEMBLE OPTIONS\fR below for a full
+list of options supported and their effects.
+.TP
+\fBnamespace ensemble configure \fIcommand\fR ?\fIoption\fR? ?\fIvalue ...\fR?
+.
+Retrieves the value of an option associated with the ensemble command
+named \fIcommand\fR, or updates some options associated with that
+ensemble command.  See the section \fBENSEMBLE OPTIONS\fR below for a
+full list of options supported and their effects.
+.TP
+\fBnamespace ensemble exists\fR \fIcommand\fR
+.
+Returns a boolean value that describes whether the command
+\fIcommand\fR exists and is an ensemble command.  This command only
+ever returns an error if the number of arguments to the command is
+wrong.
+.PP
+When called, an ensemble command takes its first argument and looks it
+up (according to the rules described below) to discover a list of
+words to replace the ensemble command and subcommand with.  The
+resulting list of words is then evaluated (with no further
+substitutions) as if that was what was typed originally (i.e. by
+passing the list of words through \fBTcl_EvalObjv\fR) and returning
+the result of the command.  Note that it is legal to make the target
+of an ensemble rewrite be another (or even the same) ensemble
+command.  The ensemble command will not be visible through the use of
+the \fBuplevel\fR or \fBinfo level\fR commands.
+.SS "ENSEMBLE OPTIONS"
+.PP
+The following options, supported by the \fBnamespace ensemble
+create\fR and \fBnamespace ensemble configure\fR commands, control how
+an ensemble command behaves:
+.TP
+\fB\-map\fR
+.
+When non-empty, this option supplies a dictionary that provides a
+mapping from subcommand names to a list of prefix words to substitute
+in place of the ensemble command and subcommand words (in a manner
+similar to an alias created with \fBinterp alias\fR; the words are not
+reparsed after substitution); if the first word of any target is not
+fully qualified when set, it is assumed to be relative to the
+\fIcurrent\fR namespace and changed to be exactly that (that is, it is
+always fully qualified when read). When this option is empty, the mapping
+will be from the local name of the subcommand to its fully-qualified
+name.  Note that when this option is non-empty and the
+\fB\-subcommands\fR option is empty, the ensemble subcommand names
+will be exactly those words that have mappings in the dictionary.
+.TP
+\fB\-parameters\fR
+.VS 8.6
+This option gives a list of named arguments (the names being used during
+generation of error messages) that are passed by the caller of the ensemble
+between the name of the ensemble and the subcommand argument. By default, it
+is the empty list.
+.VE 8.6
+.TP
+\fB\-prefixes\fR
+.
+This option (which is enabled by default) controls whether the
+ensemble command recognizes unambiguous prefixes of its subcommands.
+When turned off, the ensemble command requires exact matching of
+subcommand names.
+.TP
+\fB\-subcommands\fR
+.
+When non-empty, this option lists exactly what subcommands are in the
+ensemble.  The mapping for each of those commands will be either whatever
+is defined in the \fB\-map\fR option, or to the command with the same
+name in the namespace linked to the ensemble.  If this option is
+empty, the subcommands of the namespace will either be the keys of the
+dictionary listed in the \fB\-map\fR option or the exported commands
+of the linked namespace at the time of the invocation of the ensemble
+command.
+.TP
+\fB\-unknown\fR
+.
+When non-empty, this option provides a partial command (to which all
+the words that are arguments to the ensemble command, including the
+fully-qualified name of the ensemble, are appended) to handle the case
+where an ensemble subcommand is not recognized and would otherwise
+generate an error.  When empty (the default) an error (in the style of
+\fBTcl_GetIndexFromObj\fR) is generated whenever the ensemble is
+unable to determine how to implement a particular subcommand.  See
+\fBUNKNOWN HANDLER BEHAVIOUR\fR for more details.
+.PP
+The following extra option is allowed by \fBnamespace ensemble
+create\fR:
+.TP
+\fB\-command\fR
+.
+This write-only option allows the name of the ensemble created by
+\fBnamespace ensemble create\fR to be anything in any existing
+namespace.  The default value for this option is the fully-qualified
+name of the namespace in which the \fBnamespace ensemble create\fR
+command is invoked.
+.PP
+The following extra option is allowed by \fBnamespace ensemble
+configure\fR:
+.TP
+\fB\-namespace\fR
+.
+This read-only option allows the retrieval of the fully-qualified name
+of the namespace which the ensemble was created within.
+.SS "UNKNOWN HANDLER BEHAVIOUR"
+.PP
+If an unknown handler is specified for an ensemble, that handler is
+called when the ensemble command would otherwise return an error due
+to it being unable to decide which subcommand to invoke. The exact
+conditions under which that occurs are controlled by the
+\fB\-subcommands\fR, \fB\-map\fR and \fB\-prefixes\fR options as
+described above.
+.PP
+To execute the unknown handler, the ensemble mechanism takes the
+specified \fB\-unknown\fR option and appends each argument of the
+attempted ensemble command invocation (including the ensemble command
+itself, expressed as a fully qualified name). It invokes the resulting
+command in the scope of the attempted call. If the execution of the
+unknown handler terminates normally, the ensemble engine reparses the
+subcommand (as described below) and tries to dispatch it again, which
+is ideal for when the ensemble's configuration has been updated by the
+unknown subcommand handler. Any other kind of termination of the
+unknown handler is treated as an error.
+.PP
+The result of the unknown handler is expected to be a list (it is an
+error if it is not). If the list is an empty list, the ensemble
+command attempts to look up the original subcommand again and, if it
+is not found this time, an error will be generated just as if the
+\fB\-unknown\fR handler was not there (i.e. for any particular
+invocation of an ensemble, its unknown handler will be called at most
+once.) This makes it easy for the unknown handler to update the
+ensemble or its backing namespace so as to provide an implementation
+of the desired subcommand and reparse.
+.PP
+When the result is a non-empty list, the words of that list are used
+to replace the ensemble command and subcommand, just as if they had
+been looked up in the \fB\-map\fR. It is up to the unknown handler to
+supply all namespace qualifiers if the implementing subcommand is not
+in the namespace of the caller of the ensemble command. Also note that
+when ensemble commands are chained (e.g. if you make one of the
+commands that implement an ensemble subcommand into an ensemble, in a
+manner similar to the \fBtext\fR widget's tag and mark subcommands) then the
+rewrite happens in the context of the caller of the outermost
+ensemble. That is to say that ensembles do not in themselves place any
+namespace contexts on the Tcl call stack.
+.PP
+Where an empty \fB\-unknown\fR handler is given (the default), the
+ensemble command will generate an error message based on the list of
+commands that the ensemble has defined (formatted similarly to the
+error message from \fBTcl_GetIndexFromObj\fR). This is the error that
+will be thrown when the subcommand is still not recognized during
+reparsing. It is also an error for an \fB\-unknown\fR handler to
+delete its namespace.
+.SH EXAMPLES

+.SH NAME
+next, nextto \- invoke superclass method implementations
+.SH SYNOPSIS
+.nf
+package require TclOO
+
+\fBnext\fR ?\fIarg ...\fR?
+\fBnextto\fI class\fR ?\fIarg ...\fR?
+.fi
+.BE
+
+.SH DESCRIPTION
+.PP
+The \fBnext\fR command is used to call implementations of a method by a class,
+superclass or mixin that are overridden by the current method. It can only be
+used from within a method. It is also used within filters to indicate the
+point where a filter calls the actual implementation (the filter may decide to
+not go along the chain, and may process the results of going along the chain
+of methods as it chooses). The result of the \fBnext\fR command is the result
+of the next method in the method chain; if there are no further methods in the
+method chain, the result of \fBnext\fR will be an error. The arguments,
+\fIarg\fR, to \fBnext\fR are the arguments to pass to the next method in the
+chain.
+.PP
+The \fBnextto\fR command is the same as the \fBnext\fR command, except that it
+takes an additional \fIclass\fR argument that identifies a class whose
+implementation of the current method chain (see \fBinfo object\fR \fBcall\fR) should
+be used; the method implementation selected will be the one provided by the
+given class, and it must refer to an existing non-filter invocation that lies
+further along the chain than the current implementation.
+.SH "THE METHOD CHAIN"
+.PP
+When a method of an object is invoked, things happen in several stages:
+.IP [1]
+The structure of the object, its class, superclasses, filters, and mixins, are
+examined to build a \fImethod chain\fR, which contains a list of method
+implementations to invoke.
+.IP [2]
+The first method implementation on the chain is invoked.
+.IP [3]
+If that method implementation invokes the \fBnext\fR command, the next method
+implementation is invoked (with its arguments being those that were passed to
+\fBnext\fR).
+.IP [4]
+The result from the overall method call is the result from the outermost
+method implementation; inner method implementations return their results
+through \fBnext\fR.
+.IP [5]
+The method chain is cached for future use.
+.SS "METHOD SEARCH ORDER"
+.PP
+When constructing the method chain, method implementations are searched for in
+the following order:
+.IP [1]
+In the object.
+.IP [2]
+In the classes mixed into the object, in class traversal order. The list of
+mixins is checked in natural order.
+.IP [3]
+In the classes mixed into the classes of the object, with sources of mixing in
+being searched in class traversal order. Within each class, the list of mixins
+is processed in natural order.
+.IP [4]
+In the object's class.
+.IP [5]
+In the superclasses of the class, following each superclass in a depth-first
+fashion in the natural order of the superclass list.
+.PP
+Any particular method implementation always comes as \fIlate\fR in the
+resulting list of implementations as possible.
+.SS FILTERS
+.PP
+When an object has a list of filter names set upon it, or is an instance of a
+class (or has mixed in a class) that has a list of filter names set upon it,
+before every invocation of any method the filters are processed. Filter
+implementations are found in class traversal order, as are the lists of filter
+names (each of which is traversed in natural list order). Explicitly invoking
+a method used as a filter will cause that method to be invoked twice, once as
+a filter and once as a normal method.
+.PP
+Each filter should decide for itself whether to permit the execution to go
+forward to the proper implementation of the method (which it does by invoking
+the \fBnext\fR command as filters are inserted into the front of the method
+call chain) and is responsible for returning the result of \fBnext\fR.
+.PP
+Filters are not invoked when processing an invocation of the \fBunknown\fR
+method because of a failure to locate a method implementation, or when
+invoking either constructors or destructors.
+.SH EXAMPLES
+.PP
+This example demonstrates how to use the \fBnext\fR command to call the
+(super)class's implementation of a method. The script:
+.PP
+.CS
+oo::class create theSuperclass {
+    method example {args} {
+        puts "in the superclass, args = $args"
+    }
+}
+oo::class create theSubclass {
+    superclass theSuperclass
+    method example {args} {
+        puts "before chaining from subclass, args = $args"
+        \fBnext\fR a {*}$args b
+        \fBnext\fR pureSynthesis
+        puts "after chaining from subclass"
+    }
+}
+theSubclass create obj
+oo::define obj method example args {
+    puts "per-object method, args = $args"
+    \fBnext\fR x {*}$args y
+    \fBnext\fR
+}
+obj example 1 2 3
+.CE
+.PP
+prints the following:
+.PP
+.CS
+per-object method, args = 1 2 3
+before chaining from subclass, args = x 1 2 3 y
+in the superclass, args = a x 1 2 3 y b
+in the superclass, args = pureSynthesis
+after chaining from subclass
+before chaining from subclass, args = 
+in the superclass, args = a b
+in the superclass, args = pureSynthesis
+after chaining from subclass
+.CE
+.PP
+This example demonstrates how to build a simple cache class that applies
+memoization to all the method calls of the objects it is mixed into, and shows
+how it can make a difference to computation times:
+.PP
+.CS
+oo::class create cache {
+    filter Memoize
+    method Memoize args {
+        \fI# Do not filter the core method implementations\fR
+        if {[lindex [self target] 0] eq "::oo::object"} {
+            return [\fBnext\fR {*}$args]
+        }
+
+        \fI# Check if the value is already in the cache\fR
+        my variable ValueCache
+        set key [self target],$args
+        if {[info exist ValueCache($key)]} {
+            return $ValueCache($key)
+        }
+
+        \fI# Compute value, insert into cache, and return it\fR
+        return [set ValueCache($key) [\fBnext\fR {*}$args]]
+    }
+    method flushCache {} {
+        my variable ValueCache
+        unset ValueCache
+        \fI# Skip the caching\fR
+        return -level 2 ""
+    }
+}
+
+oo::object create demo
+oo::define demo {
+    mixin cache
+    method compute {a b c} {
+        after 3000 \fI;# Simulate deep thought\fR

+    }
+    method compute2 {a b c} {

+.SH NAME
+oo::object \- root class of the class hierarchy
+.SH SYNOPSIS
+.nf
+package require TclOO
+
+\fBoo::object\fI method \fR?\fIarg ...\fR?
+.fi
+.SH "CLASS HIERARCHY"
+.nf
+\fBoo::object\fR
+.fi
+.BE
+.SH DESCRIPTION
+.PP
+The \fBoo::object\fR class is the root class of the object hierarchy; every
+object is an instance of this class. Since classes are themselves objects,
+they are instances of this class too. Objects are always referred to by their
+name, and may be \fBrename\fRd while maintaining their identity.
+.PP
+Instances of objects may be made with either the \fBcreate\fR or \fBnew\fR
+methods of the \fBoo::object\fR object itself, or by invoking those methods on
+any of the subclass objects; see \fBoo::class\fR for more details. The
+configuration of individual objects (i.e., instance-specific methods, mixed-in
+classes, etc.) may be controlled with the \fBoo::objdefine\fR command.
+.PP
+Each object has a unique namespace associated with it, the instance namespace.
+This namespace holds all the instance variables of the object, and will be the
+current namespace whenever a method of the object is invoked (including a
+method of the class of the object). When the object is destroyed, its instance
+namespace is deleted. The instance namespace contains the object's \fBmy\fR
+command, which may be used to invoke non-exported methods of the object or to
+create a reference to the object for the purpose of invocation which persists
+across renamings of the object.
+.SS CONSTRUCTOR
+The \fBoo::object\fR class does not define an explicit constructor.
+.SS DESTRUCTOR
+The \fBoo::object\fR class does not define an explicit destructor.
+.SS "EXPORTED METHODS"
+The \fBoo::object\fR class supports the following exported methods:
+.TP
+\fIobj \fBdestroy\fR
+.
+This method destroys the object, \fIobj\fR, that it is invoked upon, invoking
+any destructors on the object's class in the process. It is equivalent to
+using \fBrename\fR to delete the object command. The result of this method is
+always the empty string.
+.SS "NON-EXPORTED METHODS"
+.PP
+The \fBoo::object\fR class supports the following non-exported methods:
+.TP
+\fIobj \fBeval\fR ?\fIarg ...\fR?
+.
+This method concatenates the arguments, \fIarg\fR, as if with \fBconcat\fR,
+and then evaluates the resulting script in the namespace that is uniquely
+associated with \fIobj\fR, returning the result of the evaluation.
+.TP
+\fIobj \fBunknown ?\fImethodName\fR? ?\fIarg ...\fR?
+.
+This method is called when an attempt to invoke the method \fImethodName\fR on
+object \fIobj\fR fails. The arguments that the user supplied to the method are
+given as \fIarg\fR arguments.
+.VS
+If \fImethodName\fR is absent, the object was invoked with no method name at
+all (or any other arguments).
+.VE
+The default implementation (i.e., the one defined by the \fBoo::object\fR
+class) generates a suitable error, detailing what methods the object supports
+given whether the object was invoked by its public name or through the
+\fBmy\fR command.
+.TP
+\fIobj \fBvariable \fR?\fIvarName ...\fR?
+.
+This method arranges for each variable called \fIvarName\fR to be linked from
+the object \fIobj\fR's unique namespace into the caller's context. Thus, if it
+is invoked from inside a procedure then the namespace variable in the object
+is linked to the local variable in the procedure. Each \fIvarName\fR argument
+must not have any namespace separators in it. The result is the empty string.
+.TP
+\fIobj \fBvarname \fIvarName\fR
+.
+This method returns the globally qualified name of the variable \fIvarName\fR
+in the unique namespace for the object \fIobj\fR.
+.TP
+\fIobj \fB<cloned> \fIsourceObjectName\fR
+.VS
+This method is used by the \fBoo::object\fR command to copy the state of one
+object to another. It is responsible for copying the procedures and variables
+of the namespace of the source object (\fIsourceObjectName\fR) to the current
+object. It does not copy any other types of commands or any traces on the
+variables; that can be added if desired by overriding this method in a
+subclass.
+.VE
+.SH EXAMPLES
+.PP
+This example demonstrates basic use of an object.

+.SH NAME

+.SH SYNOPSIS
+.sp
+\fBopen \fIfileName\fR
+.br
+\fBopen \fIfileName access\fR
+.br
+\fBopen \fIfileName access permissions\fR
+.BE
+.SH DESCRIPTION
+.PP
+This command opens a file, serial port, or command pipeline and returns a
+channel identifier that may be used in future invocations of commands like
+\fBread\fR, \fBputs\fR, and \fBclose\fR.
+If the first character of \fIfileName\fR is not \fB|\fR then
+the command opens a file:
+\fIfileName\fR gives the name of the file to open, and it must conform to the
+conventions described in the \fBfilename\fR manual entry.
+.PP
+The \fIaccess\fR argument, if present, indicates the way in which the file
+(or command pipeline) is to be accessed.
+In the first form \fIaccess\fR may have any of the following values:
+.TP 15
+\fBr\fR
+.
+Open the file for reading only; the file must already exist. This is the
+default value if \fIaccess\fR is not specified.
+.TP 15
+\fBr+\fR
+.
+Open the file for both reading and writing; the file must
+already exist.
+.TP 15
+\fBw\fR
+.
+Open the file for writing only.  Truncate it if it exists.  If it does not
+exist, create a new file.
+.TP 15
+\fBw+\fR
+.
+Open the file for reading and writing.  Truncate it if it exists.
+If it does not exist, create a new file.
+.TP 15
+\fBa\fR
+.
+Open the file for writing only.  If the file does not exist,
+create a new empty file.
+Set the file pointer to the end of the file prior to each write.
+.TP 15
+\fBa+\fR
+.
+Open the file for reading and writing.  If the file does not exist,
+create a new empty file.
+Set the initial access position  to the end of the file.
+.PP
+All of the legal \fIaccess\fR values above may have the character
+\fBb\fR added as the second or third character in the value to
+indicate that the opened channel should be configured as if with the
+\fBfconfigure\fR \fB\-translation binary\fR option, making the channel suitable for 
+reading or writing of binary data.
+.PP
+In the second form, \fIaccess\fR consists of a list of any of the
+following flags, all of which have the standard POSIX meanings.
+One of the flags must be either \fBRDONLY\fR, \fBWRONLY\fR or \fBRDWR\fR.
+.TP 15
+\fBRDONLY\fR
+.
+Open the file for reading only.
+.TP 15
+\fBWRONLY\fR
+.
+Open the file for writing only.
+.TP 15
+\fBRDWR\fR
+.
+Open the file for both reading and writing.
+.TP 15
+\fBAPPEND\fR
+.
+Set the file pointer to the end of the file prior to each write.
+.TP 15
+\fBBINARY\fR
+.
+Configure the opened channel with the \fB\-translation binary\fR option.
+.TP 15
+\fBCREAT\fR
+.
+Create the file if it does not already exist (without this flag it
+is an error for the file not to exist).
+.TP 15
+\fBEXCL\fR
+.
+If \fBCREAT\fR is also specified, an error is returned if the
+file already exists.
+.TP 15
+\fBNOCTTY\fR
+.
+If the file is a terminal device, this flag prevents the file from
+becoming the controlling terminal of the process.
+.TP 15
+\fBNONBLOCK\fR
+.
+Prevents the process from blocking while opening the file, and
+possibly in subsequent I/O operations.  The exact behavior of
+this flag is system- and device-dependent;  its use is discouraged
+(it is better to use the \fBfconfigure\fR command to put a file
+in nonblocking mode).
+For details refer to your system documentation on the \fBopen\fR system
+call's \fBO_NONBLOCK\fR flag.
+.TP 15
+\fBTRUNC\fR
+.
+If the file exists it is truncated to zero length.
+.PP
+If a new file is created as part of opening it, \fIpermissions\fR
+(an integer) is used to set the permissions for the new file in
+conjunction with the process's file mode creation mask.
+\fIPermissions\fR defaults to 0666.
+.SH "COMMAND PIPELINES"
+.PP
+If the first character of \fIfileName\fR is
+.QW \fB|\fR
+then the
+remaining characters of \fIfileName\fR are treated as a list of arguments
+that describe a command pipeline to invoke, in the same style as the
+arguments for \fBexec\fR.
+In this case, the channel identifier returned by \fBopen\fR may be used
+to write to the command's input pipe or read from its output pipe,
+depending on the value of \fIaccess\fR.
+If write-only access is used (e.g. \fIaccess\fR is
+.QW \fBw\fR ),
+then standard output for the pipeline is directed to the current standard
+output unless overridden by the command.
+If read-only access is used (e.g. \fIaccess\fR is
+.QW \fBr\fR ),
+standard input for the pipeline is taken from the current standard
+input unless overridden by the command.
+The id of the spawned process is accessible through the \fBpid\fR
+command, using the channel id returned by \fBopen\fR as argument.
+.PP
+If the command (or one of the commands) executed in the command
+pipeline returns an error (according to the definition in \fBexec\fR),
+a Tcl error is generated when \fBclose\fR is called on the channel
+unless the pipeline is in non-blocking mode then no exit status is
+returned (a silent \fBclose\fR with -blocking 0).
+.PP
+It is often useful to use the \fBfileevent\fR command with pipelines
+so other processing may happen at the same time as running the command
+in the background.
+.SH "SERIAL COMMUNICATIONS"
+.PP
+If \fIfileName\fR refers to a serial port, then the specified serial port
+is opened and initialized in a platform-dependent manner.  Acceptable
+values for the \fIfileName\fR to use to open a serial port are described in
+the PORTABILITY ISSUES section.
+.PP
+The \fBfconfigure\fR command can be used to query and set additional
+configuration options specific to serial ports (where supported):
+.TP
+\fB\-mode\fR \fIbaud\fB,\fIparity\fB,\fIdata\fB,\fIstop\fR
+.
+This option is a set of 4 comma-separated values: the baud rate, parity,
+number of data bits, and number of stop bits for this serial port.  The
+\fIbaud\fR rate is a simple integer that specifies the connection speed.
+\fIParity\fR is one of the following letters: \fBn\fR, \fBo\fR, \fBe\fR,
+\fBm\fR, \fBs\fR; respectively signifying the parity options of
+.QW none ,
+.QW odd ,
+.QW even ,
+.QW mark ,
+or
+.QW space .
+\fIData\fR is the number of
+data bits and should be an integer from 5 to 8, while \fIstop\fR is the
+number of stop bits and should be the integer 1 or 2.
+.TP
+\fB\-handshake\fR \fItype\fR
+.
+(Windows and Unix). This option is used to setup automatic handshake
+control. Note that not all handshake types maybe supported by your operating
+system. The \fItype\fR parameter is case-independent.
+.RS
+.PP
+If \fItype\fR is \fBnone\fR then any handshake is switched off.
+\fBrtscts\fR activates hardware handshake. Hardware handshake signals
+are described below.
+For software handshake \fBxonxoff\fR the handshake characters can be redefined
+with \fB\-xchar\fR.
+An additional hardware handshake \fBdtrdsr\fR is available only under Windows.
+There is no default handshake configuration, the initial value depends
+on your operating system settings.
+The \fB\-handshake\fR option cannot be queried.
+.RE
+.TP
+\fB\-queue\fR
+.
+(Windows and Unix). The \fB\-queue\fR option can only be queried.
+It returns a list of two integers representing the current number
+of bytes in the input and output queue respectively.
+.TP
+\fB\-timeout\fR \fImsec\fR
+.
+(Windows and Unix). This option is used to set the timeout for blocking
+read operations. It specifies the maximum interval between the
+reception of two bytes in milliseconds.
+For Unix systems the granularity is 100 milliseconds.
+The \fB\-timeout\fR option does not affect write operations or
+nonblocking reads.
+This option cannot be queried.
+.TP
+\fB\-ttycontrol\fR \fI{signal boolean signal boolean ...}\fR
+.
+(Windows and Unix). This option is used to setup the handshake
+output lines (see below) permanently or to send a BREAK over the serial line.
+The \fIsignal\fR names are case-independent.
+\fB{RTS 1 DTR 0}\fR sets the RTS output to high and the DTR output to low.
+The BREAK condition (see below) is enabled and disabled with \fB{BREAK 1}\fR and
+\fB{BREAK 0}\fR respectively.
+It is not a good idea to change the \fBRTS\fR (or \fBDTR\fR) signal
+with active hardware handshake \fBrtscts\fR (or \fBdtrdsr\fR).
+The result is unpredictable.
+The \fB\-ttycontrol\fR option cannot be queried.
+.TP
+\fB\-ttystatus\fR
+.
+(Windows and Unix). The \fB\-ttystatus\fR option can only be
+queried.  It returns the current modem status and handshake input signals
+(see below).
+The result is a list of signal,value pairs with a fixed order,
+e.g. \fB{CTS 1 DSR 0 RING 1 DCD 0}\fR.
+The \fIsignal\fR names are returned upper case.
+.TP
+\fB\-xchar\fR \fI{xonChar xoffChar}\fR
+.
+(Windows and Unix). This option is used to query or change the software
+handshake characters. Normally the operating system default should be
+DC1 (0x11) and DC3 (0x13) representing the ASCII standard
+XON and XOFF characters.
+.TP
+\fB\-pollinterval\fR \fImsec\fR
+.
+(Windows only). This option is used to set the maximum time between
+polling for fileevents.
+This affects the time interval between checking for events throughout the Tcl
+interpreter (the smallest value always wins).  Use this option only if
+you want to poll the serial port more or less often than 10 msec
+(the default).
+.TP
+\fB\-sysbuffer\fR \fIinSize\fR
+.TP
+\fB\-sysbuffer\fR \fI{inSize outSize}\fR
+.
+(Windows only). This option is used to change the size of Windows
+system buffers for a serial channel. Especially at higher communication
+rates the default input buffer size of 4096 bytes can overrun
+for latent systems. The first form specifies the input buffer size,
+in the second form both input and output buffers are defined.
+.TP
+\fB\-lasterror\fR
+.
+(Windows only). This option is query only.
+In case of a serial communication error, \fBread\fR or \fBputs\fR
+returns a general Tcl file I/O error.
+\fBfconfigure\fR \fB\-lasterror\fR can be called to get a list of error details.
+See below for an explanation of the various error codes.
+.SH "SERIAL PORT SIGNALS"
+.PP
+RS-232 is the most commonly used standard electrical interface for serial
+communications. A negative voltage (-3V..-12V) define a mark (on=1) bit and
+a positive voltage (+3..+12V) define a space (off=0) bit (RS-232C).  The
+following signals are specified for incoming and outgoing data, status
+lines and handshaking. Here we are using the terms \fIworkstation\fR for
+your computer and \fImodem\fR for the external device, because some signal
+names (DCD, RI) come from modems. Of course your external device may use
+these signal lines for other purposes.
+.IP \fBTXD\fR(output)
+\fBTransmitted Data:\fR Outgoing serial data.
+.IP \fBRXD\fR(input)
+\fBReceived Data:\fRIncoming serial data.
+.IP \fBRTS\fR(output)
+\fBRequest To Send:\fR This hardware handshake line informs the modem that
+your workstation is ready to receive data. Your workstation may
+automatically reset this signal to indicate that the input buffer is full.
+.IP \fBCTS\fR(input)
+\fBClear To Send:\fR The complement to RTS. Indicates that the modem is
+ready to receive data.
+.IP \fBDTR\fR(output)
+\fBData Terminal Ready:\fR This signal tells the modem that the workstation
+is ready to establish a link. DTR is often enabled automatically whenever a
+serial port is opened.
+.IP \fBDSR\fR(input)
+\fBData Set Ready:\fR The complement to DTR. Tells the workstation that the
+modem is ready to establish a link.
+.IP \fBDCD\fR(input)
+\fBData Carrier Detect:\fR This line becomes active when a modem detects a
+.QW Carrier
+signal.
+.IP \fBRI\fR(input)
+\fBRing Indicator:\fR Goes active when the modem detects an incoming call.
+.IP \fBBREAK\fR
+A BREAK condition is not a hardware signal line, but a logical zero on the
+TXD or RXD lines for a long period of time, usually 250 to 500
+milliseconds.  Normally a receive or transmit data signal stays at the mark
+(on=1) voltage until the next character is transferred. A BREAK is sometimes
+used to reset the communications line or change the operating mode of
+communications hardware.
+.SH "ERROR CODES (Windows only)"
+.PP
+A lot of different errors may occur during serial read operations or during
+event polling in background. The external device may have been switched
+off, the data lines may be noisy, system buffers may overrun or your mode
+settings may be wrong.  That is why a reliable software should always
+\fBcatch\fR serial read operations.  In cases of an error Tcl returns a
+general file I/O error.  Then \fBfconfigure\fR \fB\-lasterror\fR may help to
+locate the problem.  The following error codes may be returned.
+.TP 10
+\fBRXOVER\fR
+.
+Windows input buffer overrun. The data comes faster than your scripts reads
+it or your system is overloaded. Use \fBfconfigure\fR \fB\-sysbuffer\fR to avoid a
+temporary bottleneck and/or make your script faster.
+.TP 10
+\fBTXFULL\fR
+.
+Windows output buffer overrun. Complement to RXOVER. This error should
+practically not happen, because Tcl cares about the output buffer status.
+.TP 10
+\fBOVERRUN\fR
+.
+UART buffer overrun (hardware) with data lost.
+The data comes faster than the system driver receives it.
+Check your advanced serial port settings to enable the FIFO (16550) buffer
+and/or setup a lower(1) interrupt threshold value.
+.TP 10
+\fBRXPARITY\fR
+.
+A parity error has been detected by your UART.
+Wrong parity settings with \fBfconfigure\fR \fB\-mode\fR or a noisy data line (RXD)
+may cause this error.
+.TP 10
+\fBFRAME\fR
+.
+A stop-bit error has been detected by your UART.
+Wrong mode settings with \fBfconfigure\fR \fB\-mode\fR or a noisy data line (RXD)
+may cause this error.
+.TP 10
+\fBBREAK\fR
+.
+A BREAK condition has been detected by your UART (see above).
+.SH "PORTABILITY ISSUES"
+.TP
+\fBWindows \fR(all versions)
+.
+Valid values for \fIfileName\fR to open a serial port are of the form
+\fBcom\fIX\fB:\fR, where \fIX\fR is a number, generally from 1 to 4.
+This notation only works for serial ports from 1 to 9, if the system
+happens to have more than four.  An attempt to open a serial port that
+does not exist or has a number greater than 9 will fail.  An alternate
+form of opening serial ports is to use the filename \fB\e\e.\ecomX\fR,
+where X is any number that corresponds to a serial port; please note
+that this method is considerably slower on Windows 95 and Windows 98.
+.TP
+\fBWindows NT\fR
+.
+When running Tcl interactively, there may be some strange interactions
+between the real console, if one is present, and a command pipeline that uses
+standard input or output.  If a command pipeline is opened for reading, some
+of the lines entered at the console will be sent to the command pipeline and
+some will be sent to the Tcl evaluator.  If a command pipeline is opened for
+writing, keystrokes entered into the console are not visible until the
+pipe is closed.  This behavior occurs whether the command pipeline is
+executing 16-bit or 32-bit applications.  These problems only occur because
+both Tcl and the child application are competing for the console at
+the same time.  If the command pipeline is started from a script, so that Tcl
+is not accessing the console, or if the command pipeline does not use

+\fBWindows 95\fR

+.SH DESCRIPTION
+.PP
+This command keeps a simple database of the packages available for
+use by the current interpreter and how to load them into the
+interpreter.
+It supports multiple versions of each package and arranges
+for the correct version of a package to be loaded based on what
+is needed by the application.
+This command also detects and reports version clashes.
+Typically, only the \fBpackage require\fR and \fBpackage provide\fR
+commands are invoked in normal Tcl scripts;  the other commands are used
+primarily by system scripts that maintain the package database.
+.PP
+The behavior of the \fBpackage\fR command is determined by its first argument.
+The following forms are permitted:
+.TP
+\fBpackage forget\fR ?\fIpackage package ...\fR?
+.
+Removes all information about each specified package from this interpreter,
+including information provided by both \fBpackage ifneeded\fR and
+\fBpackage provide\fR.
+.TP
+\fBpackage ifneeded \fIpackage version\fR ?\fIscript\fR?
+.
+This command typically appears only in system configuration
+scripts to set up the package database.
+It indicates that a particular version of
+a particular package is available if needed, and that the package
+can be added to the interpreter by executing \fIscript\fR.
+The script is saved in a database for use by subsequent
+\fBpackage require\fR commands;  typically, \fIscript\fR
+sets up auto-loading for the commands in the package (or calls
+\fBload\fR and/or \fBsource\fR directly), then invokes
+\fBpackage provide\fR to indicate that the package is present.
+There may be information in the database for several different
+versions of a single package.
+If the database already contains information for \fIpackage\fR
+and \fIversion\fR, the new \fIscript\fR replaces the existing
+one.
+If the \fIscript\fR argument is omitted, the current script for
+version \fIversion\fR of package \fIpackage\fR is returned,
+or an empty string if no \fBpackage ifneeded\fR command has
+been invoked for this \fIpackage\fR and \fIversion\fR.
+.TP
+\fBpackage names\fR
+.
+Returns a list of the names of all packages in the
+interpreter for which a version has been provided (via
+\fBpackage provide\fR) or for which a \fBpackage ifneeded\fR
+script is available.
+The order of elements in the list is arbitrary.
+.TP
+\fBpackage present\fR ?\fB\-exact\fR? \fIpackage\fR ?\fIrequirement...\fR?
+.
+This command is equivalent to \fBpackage require\fR except that it
+does not try and load the package if it is not already loaded.
+.TP
+\fBpackage provide \fIpackage \fR?\fIversion\fR?
+.
+This command is invoked to indicate that version \fIversion\fR
+of package \fIpackage\fR is now present in the interpreter.
+It is typically invoked once as part of an \fBifneeded\fR script,
+and again by the package itself when it is finally loaded.
+An error occurs if a different version of \fIpackage\fR has been
+provided by a previous \fBpackage provide\fR command.
+If the \fIversion\fR argument is omitted, then the command
+returns the version number that is currently provided, or an
+empty string if no \fBpackage provide\fR command has been
+invoked for \fIpackage\fR in this interpreter.  
+.TP
+\fBpackage require \fR\fIpackage \fR?\fIrequirement...\fR?
+.
+This command is typically invoked by Tcl code that wishes to use
+a particular version of a particular package.  The arguments
+indicate which package is wanted, and the command ensures that
+a suitable version of the package is loaded into the interpreter.
+If the command succeeds, it returns the version number that is
+loaded;  otherwise it generates an error.
+.RS
+.PP
+A suitable version of the package is any version which satisfies at
+least one of the requirements, per the rules of \fBpackage
+vsatisfies\fR. If multiple versions are suitable the implementation
+with the highest version is chosen. This last part is additionally
+influenced by the selection mode set with \fBpackage prefer\fR.
+.PP
+In the
+.QW stable
+selection mode the command will select the highest
+stable version satisfying the requirements, if any. If no stable
+version satisfies the requirements, the highest unstable version
+satisfying the requirements will be selected.  In the
+.QW latest
+selection mode the command will accept the highest version satisfying
+all the requirements, regardless of its stableness.
+.PP
+If a version of \fIpackage\fR has already been provided (by invoking
+the \fBpackage provide\fR command), then its version number must
+satisfy the \fIrequirement\fRs and the command returns immediately.
+Otherwise, the command searches the database of information provided by
+previous \fBpackage ifneeded\fR commands to see if an acceptable
+version of the package is available.
+If so, the script for the highest acceptable version number is evaluated
+in the global namespace;
+it must do whatever is necessary to load the package,
+including calling \fBpackage provide\fR for the package.
+If the \fBpackage ifneeded\fR database does not contain an acceptable
+version of the package and a \fBpackage unknown\fR command has been
+specified for the interpreter then that command is evaluated in the
+global namespace;  when
+it completes, Tcl checks again to see if the package is now provided
+or if there is a \fBpackage ifneeded\fR script for it.
+If all of these steps fail to provide an acceptable version of the
+package, then the command returns an error.
+.RE
+.TP
+\fBpackage require \-exact \fIpackage version\fR
+.
+This form of the command is used when only the given \fIversion\fR

+\fBpackage unknown \fR?\fIcommand\fR?
+.
+This command supplies a

+command to invoke during
+\fBpackage require\fR if no suitable version of a package can be found
+in the \fBpackage ifneeded\fR database.
+If the \fIcommand\fR argument is supplied, it contains the first part
+of a command;  when the command is invoked during a \fBpackage require\fR
+command, Tcl appends one or more additional arguments giving the desired
+package name and requirements.
+For example, if \fIcommand\fR is \fBfoo bar\fR and later the command
+\fBpackage require test 2.4\fR is invoked, then Tcl will execute
+the command \fBfoo bar test 2.4\fR to load the package.
+If no requirements are supplied to the \fBpackage require\fR command,
+then only the name will be added to invoked command.
+If the \fBpackage unknown\fR command is invoked without a \fIcommand\fR
+argument, then the current \fBpackage unknown\fR script is returned,
+or an empty string if there is none.
+If \fIcommand\fR is specified as an empty string, then the current
+\fBpackage unknown\fR script is removed, if there is one.

+.RE
+.SH "VERSION NUMBERS"
+.PP
+Version numbers consist of one or more decimal numbers separated
+by dots, such as 2 or 1.162 or 3.1.13.1.
+The first number is called the major version number.
+Larger numbers correspond to later versions of a package, with
+leftmost numbers having greater significance.
+For example, version 2.1 is later than 1.3 and version
+3.4.6 is later than 3.3.5.
+Missing fields are equivalent to zeroes:  version 1.3 is the
+same as version 1.3.0 and 1.3.0.0, so it is earlier than 1.3.1 or 1.3.0.2.
+In addition, the letters
+.QW a
+(alpha) and/or
+.QW b
+(beta) may appear
+exactly once to replace a dot for separation. These letters
+semantically add a negative specifier into the version, where
+.QW a
+is \-2, and
+.QW b
+is \-1. Each may be specified only once, and
+.QW a
+or
+.QW b
+are mutually exclusive in a specifier. Thus 1.3a1 becomes (semantically)
+1.3.\-2.1, 1.3b1 is 1.3.\-1.1. Negative numbers are not directly allowed
+in version specifiers.
+A version number not containing the letters
+.QW a
+or
+.QW b
+as specified
+above is called a \fBstable\fR version, whereas presence of the letters
+causes the version to be called is \fBunstable\fR.
+A later version number is assumed to be upwards compatible with
+an earlier version number as long as both versions have the same
+major version number.
+For example, Tcl scripts written for version 2.3 of a package should
+work unchanged under versions 2.3.2, 2.4, and 2.5.1.
+Changes in the major version number signify incompatible changes:
+if code is written to use version 2.1 of a package, it is not guaranteed
+to work unmodified with either version 1.7.3 or version 3.1.
+.SH "PACKAGE INDICES"
+.PP
+The recommended way to use packages in Tcl is to invoke \fBpackage require\fR
+and \fBpackage provide\fR commands in scripts, and use the procedure
+\fBpkg_mkIndex\fR to create package index files.
+Once you have done this, packages will be loaded automatically
+in response to \fBpackage require\fR commands.
+See the documentation for \fBpkg_mkIndex\fR for details.
+.SH EXAMPLES
+.PP
+To state that a Tcl script requires the Tk and http packages, put this
+at the top of the script:
+.PP
+.CS
+\fBpackage require\fR Tk
+\fBpackage require\fR http
+.CE
+.PP
+To test to see if the Snack package is available and load if it is
+(often useful for optional enhancements to programs where the loss of
+the functionality is not critical) do this:
+.PP
+.CS
+if {[catch {\fBpackage require\fR Snack}]} {
+    # Error thrown - package not found.
+    # Set up a dummy interface to work around the absence
+} else {
+    # We have the package, configure the app to use it

+.SH SYNOPSIS
+.nf
+\fBpkg_mkIndex\fR ?\fIoptions...\fR? \fIdir\fR ?\fIpattern pattern ...\fR?
+.fi
+.BE
+.SH DESCRIPTION
+.PP
+\fBPkg_mkIndex\fR is a utility procedure that is part of the standard
+Tcl library.
+It is used to create index files that allow packages to be loaded
+automatically when \fBpackage require\fR commands are executed.
+To use \fBpkg_mkIndex\fR, follow these steps:
+.IP [1]
+Create the package(s).
+Each package may consist of one or more Tcl script files or binary files.
+Binary files must be suitable for loading with the \fBload\fR command
+with a single argument;  for example, if the file is \fBtest.so\fR it must
+be possible to load this file with the command \fBload test.so\fR.
+Each script file must contain a \fBpackage provide\fR command to declare
+the package and version number, and each binary file must contain
+a call to \fBTcl_PkgProvide\fR.
+.IP [2]
+Create the index by invoking \fBpkg_mkIndex\fR.
+The \fIdir\fR argument gives the name of a directory and each
+\fIpattern\fR argument is a \fBglob\fR-style pattern that selects
+script or binary files in \fIdir\fR.
+The default pattern is \fB*.tcl\fR and \fB*.[info sharedlibextension]\fR.
+.RS
+.PP
+\fBPkg_mkIndex\fR will create a file \fBpkgIndex.tcl\fR in \fIdir\fR
+with package information about all the files given by the \fIpattern\fR
+arguments.
+It does this by loading each file into a slave
+interpreter and seeing what packages
+and new commands appear (this is why it is essential to have
+\fBpackage provide\fR commands or \fBTcl_PkgProvide\fR calls
+in the files, as described above).
+If you have a package split among scripts and binary files, 
+or if you have dependencies among files,
+you may have to use the \fB\-load\fR option
+or adjust the order in which \fBpkg_mkIndex\fR processes
+the files.  See \fBCOMPLEX CASES\fR below.
+.RE
+.IP [3]
+Install the package as a subdirectory of one of the directories given by
+the \fBtcl_pkgPath\fR variable.  If \fB$tcl_pkgPath\fR contains more
+than one directory, machine-dependent packages (e.g., those that
+contain binary shared libraries) should normally be installed
+under the first directory and machine-independent packages (e.g.,
+those that contain only Tcl scripts) should be installed under the
+second directory.
+The subdirectory should include
+the package's script and/or binary files as well as the \fBpkgIndex.tcl\fR
+file.  As long as the package is installed as a subdirectory of a
+directory in \fB$tcl_pkgPath\fR it will automatically be found during
+\fBpackage require\fR commands.
+.RS
+.PP
+If you install the package anywhere else, then you must ensure that
+the directory containing the package is in the \fBauto_path\fR global variable
+or an immediate subdirectory of one of the directories in \fBauto_path\fR.
+\fBAuto_path\fR contains a list of directories that are searched
+by both the auto-loader and the package loader; by default it
+includes \fB$tcl_pkgPath\fR.
+The package loader also checks all of the subdirectories of the
+directories in \fBauto_path\fR.
+You can add a directory to \fBauto_path\fR explicitly in your
+application, or you can add the directory to your \fBTCLLIBPATH\fR
+environment variable:  if this environment variable is present,
+Tcl initializes \fBauto_path\fR from it during application startup.
+.RE
+.IP [4]
+Once the above steps have been taken, all you need to do to use a
+package is to invoke \fBpackage require\fR.
+For example, if versions 2.1, 2.3, and 3.1 of package \fBTest\fR
+have been indexed by \fBpkg_mkIndex\fR, the command
+\fBpackage require Test\fR will make version 3.1 available
+and the command \fBpackage require \-exact Test 2.1\fR will
+make version 2.1 available.
+There may be many versions of a package in the various index files
+in \fBauto_path\fR, but only one will actually be loaded in a given
+interpreter, based on the first call to \fBpackage require\fR.
+Different versions of a package may be loaded in different
+interpreters.
+.SH OPTIONS
+The optional switches are:
+.TP 15
+\fB\-direct\fR
+The generated index will implement direct loading of the package
+upon \fBpackage require\fR.  This is the default.
+.TP 15
+\fB\-lazy\fR
+The generated index will manage to delay loading the package until the
+use of one of the commands provided by the package, instead of loading
+it immediately upon \fBpackage require\fR.  This is not compatible with
+the use of \fIauto_reset\fR, and therefore its use is discouraged.
+.TP 15
+\fB\-load \fIpkgPat\fR
+The index process will pre-load any packages that exist in the
+current interpreter and match \fIpkgPat\fR into the slave interpreter used to
+generate the index.  The pattern match uses string match rules, but without
+making case distinctions.
+See \fBCOMPLEX CASES\fR below.
+.TP 15
+\fB\-verbose\fR
+Generate output during the indexing process.  Output is via
+the \fBtclLog\fR procedure, which by default prints to stderr.
+.TP 15
+\fB\-\-\fR
+End of the flags, in case \fIdir\fR begins with a dash.
+.SH "PACKAGES AND THE AUTO-LOADER"
+.PP
+The package management facilities overlap somewhat with the auto-loader,
+in that both arrange for files to be loaded on-demand.
+However, package management is a higher-level mechanism that uses
+the auto-loader for the last step in the loading process.
+It is generally better to index a package with \fBpkg_mkIndex\fR
+rather than \fBauto_mkindex\fR because the package mechanism provides
+version control:  several versions of a package can be made available
+in the index files, with different applications using different
+versions based on \fBpackage require\fR commands.
+In contrast, \fBauto_mkindex\fR does not understand versions so
+it can only handle a single version of each package. 
+It is probably not a good idea to index a given package with both
+\fBpkg_mkIndex\fR and \fBauto_mkindex\fR.
+If you use \fBpkg_mkIndex\fR to index a package, its commands cannot
+be invoked until \fBpackage require\fR has been used to select a
+version;  in contrast, packages indexed with \fBauto_mkindex\fR
+can be used immediately since there is no version control.
+.SH "HOW IT WORKS"
+.PP
+\fBPkg_mkIndex\fR depends on the \fBpackage unknown\fR command,
+the \fBpackage ifneeded\fR command, and the auto-loader.
+The first time a \fBpackage require\fR command is invoked,
+the \fBpackage unknown\fR script is invoked.
+This is set by Tcl initialization to a script that
+evaluates all of the \fBpkgIndex.tcl\fR files in the
+\fBauto_path\fR.
+The \fBpkgIndex.tcl\fR files contain \fBpackage ifneeded\fR
+commands for each version of each available package;  these commands
+invoke \fBpackage provide\fR commands to announce the
+availability of the package, and they setup auto-loader
+information to load the files of the package.
+If the \fB\-lazy\fR flag was provided when the \fBpkgIndex.tcl\fR
+was generated,
+a given file of a given version of a given package is not
+actually loaded until the first time one of its commands
+is invoked.
+Thus, after invoking \fBpackage require\fR you may
+not see the package's commands in the interpreter, but you will be able
+to invoke the commands and they will be auto-loaded.
+.SH "DIRECT LOADING"
+.PP
+Some packages, for instance packages which use namespaces and export
+commands or those which require special initialization, might select
+that their package files be loaded immediately upon \fBpackage require\fR
+instead of delaying the actual loading to the first use of one of the
+package's command. This is the default mode when generating the package
+index.  It can be overridden by specifying the \fB\-lazy\fR argument.
+.SH "COMPLEX CASES"
+Most complex cases of dependencies among scripts
+and binary files, and packages being split among scripts and
+binary files are handled OK.  However, you may have to adjust
+the order in which files are processed by \fBpkg_mkIndex\fR.
+These issues are described in detail below.
+.PP
+If each script or file contains one package, and packages
+are only contained in one file, then things are easy.
+You simply specify all files to be indexed in any order
+with some glob patterns.
+.PP
+In general, it is OK for scripts to have dependencies on other
+packages.
+If scripts contain \fBpackage require\fR commands, these are
+stubbed out in the interpreter used to process the scripts,
+so these do not cause problems.
+If scripts call into other packages in global code,
+these calls are handled by a stub \fBunknown\fR command.
+However, if scripts make variable references to other package's
+variables in global code, these will cause errors.  That is
+also bad coding style.
+.PP
+If binary files have dependencies on other packages, things
+can become tricky because it is not possible to stub out
+C-level APIs such as \fBTcl_PkgRequire\fR API
+when loading a binary file.
+For example, suppose the BLT package requires Tk, and expresses
+this with a call to \fBTcl_PkgRequire\fR in its \fBBlt_Init\fR routine.
+To support this, you must run \fBpkg_mkIndex\fR in an interpreter that
+has Tk loaded.  You can achieve this with the
+\fB\-load \fIpkgPat\fR option.  If you specify this option,
+\fBpkg_mkIndex\fR will load any packages listed by
+\fBinfo loaded\fR and that match \fIpkgPat\fR
+into the interpreter used to process files.
+In most cases this will satisfy the \fBTcl_PkgRequire\fR calls
+made by binary files.
+.PP
+If you are indexing two binary files and one depends on the other,
+you should specify the one that has dependencies last.
+This way the one without dependencies will get loaded and indexed,
+and then the package it provides
+will be available when the second file is processed.
+You may also need to load the first package into the
+temporary interpreter used to create the index by using
+the \fB\-load\fR flag;
+it will not hurt to specify package patterns that are not yet loaded.
+.PP
+If you have a package that is split across scripts and a binary file,
+then you should avoid the \fB\-load\fR flag. The problem is that
+if you load a package before computing the index it masks any
+other files that provide part of the same package.
+If you must use \fB\-load\fR,
+then you must specify the scripts first; otherwise the package loaded from
+the binary file may mask the package defined by the scripts.

+\fBplatform::generic\fR
+\fBplatform::identify\fR
+\fBplatform::patterns \fIidentifier\fR
+.fi
+.BE
+.SH DESCRIPTION
+.PP
+The \fBplatform\fR package provides several utility commands useful
+for the identification of the architecture of a machine running Tcl.
+.PP
+Whilst Tcl provides the \fBtcl_platform\fR array for identifying the
+current architecture (in particular, the platform and machine
+elements) this is not always sufficient. This is because (on Unix
+machines) \fBtcl_platform\fR reflects the values returned by the
+\fBuname\fR command and these are not standardized across platforms and
+architectures. In addition, on at least one platform (AIX) the
+\fBtcl_platform(machine)\fR contains the CPU serial number.
+.PP
+Consequently, individual applications need to manipulate the values in
+\fBtcl_platform\fR (along with the output of system specific
+utilities) - which is both inconvenient for developers, and introduces
+the potential for inconsistencies in identifying architectures and in
+naming conventions.
+.PP
+The \fBplatform\fR package prevents such fragmentation - i.e., it
+establishes a standard naming convention for architectures running Tcl
+and makes it more convenient for developers to identify the current
+architecture a Tcl program is running on.
+.SH COMMANDS
+.TP
+\fBplatform::identify\fR
+.
+This command returns an identifier describing the platform the Tcl
+core is running on. The returned identifier has the general format
+\fIOS\fR-\fICPU\fR. The \fIOS\fR part of the identifier may contain
+details like kernel version, libc version, etc., and this information
+may contain dashes as well.  The \fICPU\fR part will not contain
+dashes, making the preceding dash the last dash in the result.
+.TP
+\fBplatform::generic\fR
+.
+This command returns a simplified identifier describing the platform
+the Tcl core is running on. In contrast to \fBplatform::identify\fR it
+leaves out details like kernel version, libc version, etc. The
+returned identifier has the general format \fIOS\fR-\fICPU\fR.
+.TP
+\fBplatform::patterns \fIidentifier\fR
+.
+This command takes an identifier as returned by
+\fBplatform::identify\fR and returns a list of identifiers describing
+compatible architectures.
+.SH EXAMPLE
+.PP
+This can be used to allow an application to be shipped with multiple builds of
+a shared library, so that the same package works on many versions of an
+operating system. For example:
+.PP
+.CS
+\fBpackage require platform\fR
+# Assume that app script is .../theapp/bin/theapp.tcl
+set binDir [file dirname [file normalize [info script]]]

+.SH NAME
+platform::shell \- System identification support code and utilities
+.SH SYNOPSIS
+.nf
+\fBpackage require platform::shell ?1.1.4?\fR

+\fBplatform::shell::generic \fIshell\fR
+\fBplatform::shell::identify \fIshell\fR
+\fBplatform::shell::platform \fIshell\fR
+.fi
+.BE
+.SH DESCRIPTION
+.PP
+The \fBplatform::shell\fR package provides several utility commands useful
+for the identification of the architecture of a specific Tcl shell.
+.PP
+This package allows the identification of the architecture of a
+specific Tcl shell different from the shell running the package. The
+only requirement is that the other shell (identified by its path), is
+actually executable on the current machine.
+.PP
+While for most platform this means that the architecture of the
+interrogated shell is identical to the architecture of the running
+shell this is not generally true. A counter example are all platforms
+which have 32 and 64 bit variants and where a 64bit system is able to
+run 32bit code. For these running and interrogated shell may have
+different 32/64 bit settings and thus different identifiers.
+.PP
+For applications like a code repository it is important to identify
+the architecture of the shell which will actually run the installed
+packages, versus the architecture of the shell running the repository
+software.
+.SH COMMANDS
+.TP
+\fBplatform::shell::identify \fIshell\fR
+This command does the same identification as \fBplatform::identify\fR,
+for the specified Tcl shell, in contrast to the running shell.
+.TP
+\fBplatform::shell::generic \fIshell\fR
+This command does the same identification as \fBplatform::generic\fR,
+for the specified Tcl shell, in contrast to the running shell.
+.TP
+\fBplatform::shell::platform \fIshell\fR
+This command returns the contents of \fBtcl_platform(platform)\fR for
+the specified Tcl shell.

+\fB::tcl::prefix all\fR \fItable\fR \fIstring\fR

+.BE
+.SH DESCRIPTION
+.PP
+This document describes commands looking up a prefix in a list of strings.
+The following commands are supported:
+.TP
+\fB::tcl::prefix all\fR \fItable\fR \fIstring\fR
+.
+Returns a list of all elements in \fItable\fR that begin with the prefix
+\fIstring\fR.
+.TP
+\fB::tcl::prefix longest\fR \fItable\fR \fIstring\fR
+.
+Returns the longest common prefix of all elements in \fItable\fR that
+begin with the prefix \fIstring\fR.
+.TP
+\fB::tcl::prefix match\fR ?\fIoptions\fR? \fItable\fR \fIstring\fR
+.
+If \fIstring\fR equals one element in \fItable\fR or is a prefix to exactly
+one element, the matched element is returned. If not, the result depends
+on the \fB\-error\fR option. (It is recommended that the \fItable\fR be sorted
+before use with this subcommand, so that the list of matches presented in the
+error message also becomes sorted, though this is not strictly necessary for
+the operation of this subcommand itself.)
+.RS
+.TP
+\fB\-exact\fR\0
+.
+Accept only exact matches.
+.TP
+\fB\-message\0\fIstring\fR
+.
+Use \fIstring\fR in the error message at a mismatch. Default is
+.QW option .
+.TP
+\fB\-error\0\fIoptions\fR
+.
+The \fIoptions\fR are used when no match is found. If \fIoptions\fR is empty,
+no error is generated and an empty string is returned. Otherwise the
+\fIoptions\fR are used as \fBreturn\fR options when generating the error
+message. The default corresponds to setting
+.QW "\-level 0" .
+Example: If
+.QW "\fB\-error\fR {\-errorcode MyError \-level 1}"
+is used, an error would be generated as:
+.RS
+.PP
+.CS

+.SH NAME
+proc \- Create a Tcl procedure
+.SH SYNOPSIS
+\fBproc \fIname args body\fR
+.BE
+.SH DESCRIPTION
+.PP
+The \fBproc\fR command creates a new Tcl procedure named
+\fIname\fR, replacing
+any existing command or procedure there may have been by that name.
+Whenever the new command is invoked, the contents of \fIbody\fR will
+be executed by the Tcl interpreter.
+Normally, \fIname\fR is unqualified
+(does not include the names of any containing namespaces),
+and the new procedure is created in the current namespace.
+If \fIname\fR includes any namespace qualifiers,
+the procedure is created in the specified namespace.
+\fIArgs\fR specifies the formal arguments to the
+procedure.  It consists of a list, possibly empty, each of whose
+elements specifies
+one argument.  Each argument specifier is also a list with either
+one or two fields.  If there is only a single field in the specifier
+then it is the name of the argument; if there are two fields, then
+the first is the argument name and the second is its default value. 
+Arguments with default values that are followed by non-defaulted
+arguments become required arguments.  In 8.6 this will be considered an 
+error. 
+.PP
+When \fIname\fR is invoked a local variable
+will be created for each of the formal arguments to the procedure; its
+value will be the value of corresponding argument in the invoking command
+or the argument's default value.
+Actual arguments are assigned to formal arguments strictly in order.
+Arguments with default values need not be
+specified in a procedure invocation.  However, there must be enough
+actual arguments for all the
+formal arguments that do not have defaults, and there must not be any extra
+actual arguments.  
+Arguments with default values that are followed by non-defaulted
+arguments become required arguments (in 8.6 it will be considered an 
+error).
+There is one special case to permit procedures with
+variable numbers of arguments.  If the last formal argument has the name
+\fBargs\fR, then a call to the procedure may contain more actual arguments
+than the procedure has formal arguments.  In this case, all of the actual arguments
+starting at the one that would be assigned to \fBargs\fR are combined into
+a list (as if the \fBlist\fR command had been used); this combined value
+is assigned to the local variable \fBargs\fR.
+.PP
+When \fIbody\fR is being executed, variable names normally refer to
+local variables, which are created automatically when referenced and
+deleted when the procedure returns.  One local variable is automatically
+created for each of the procedure's arguments.
+Other variables can only be accessed by invoking one of the \fBglobal\fR, 
+\fBvariable\fR, \fBupvar\fR or \fBnamespace upvar\fR commands.
+The current namespace when \fIbody\fR is executed will be the
+namespace that the procedure's name exists in, which will be the
+namespace that it was created in unless it has been changed with
+\fBrename\fR.
+'\" We may change this! It makes [variable] unstable when renamed and is
+'\" frankly pretty crazy, but doing it right is harder than it looks.
+.PP
+The \fBproc\fR command returns an empty string.  When a procedure is
+invoked, the procedure's return value is the value specified in a
+\fBreturn\fR command.  If the procedure does not execute an explicit
+\fBreturn\fR, then its return value is the value of the last command
+executed in the procedure's body.
+If an error occurs while executing the procedure
+body, then the procedure-as-a-whole will return that same error.
+.SH EXAMPLES
+.PP
+This is a procedure that accepts arbitrarily many arguments and prints
+them out, one by one.
+.PP
+.CS
+\fBproc\fR printArguments args {
+    foreach arg $args {
+        puts $arg
+    }
+}
+.CE
+.PP
+This procedure is a bit like the \fBincr\fR command, except it
+multiplies the contents of the named variable by the value, which
+defaults to \fB2\fR:
+.PP
+.CS
+\fBproc\fR mult {varName {multiplier 2}} {
+    upvar 1 $varName var
+    set var [expr {$var * $multiplier}]

+.SH NAME
+puts \- Write to a channel
+.SH SYNOPSIS
+\fBputs \fR?\fB\-nonewline\fR? ?\fIchannelId\fR? \fIstring\fR
+.BE
+.SH DESCRIPTION
+.PP
+Writes the characters given by \fIstring\fR to the channel given
+by \fIchannelId\fR.
+.PP
+\fIChannelId\fR must be an identifier for an open channel such as a
+Tcl standard channel (\fBstdout\fR or \fBstderr\fR), the return
+value from an invocation of \fBopen\fR or \fBsocket\fR, or the result
+of a channel creation command provided by a Tcl extension. The channel
+must have been opened for output.
+.PP
+If no \fIchannelId\fR is specified then it defaults to
+\fBstdout\fR. \fBPuts\fR normally outputs a newline character after
+\fIstring\fR, but this feature may be suppressed by specifying the
+\fB\-nonewline\fR switch.
+.PP
+Newline characters in the output are translated by \fBputs\fR to
+platform-specific end-of-line sequences according to the current
+value of the \fB\-translation\fR option for the channel (for example,
+on PCs newlines are normally replaced with carriage-return-linefeed
+sequences.
+See the \fBfconfigure\fR manual entry for a discussion on ways in
+which \fBfconfigure\fR will alter output.
+.PP
+Tcl buffers output internally, so characters written with \fBputs\fR
+may not appear immediately on the output file or device;  Tcl will
+normally delay output until the buffer is full or the channel is
+closed.
+You can force output to appear immediately with the \fBflush\fR
+command.
+.PP
+When the output buffer fills up, the \fBputs\fR command will normally
+block until all the buffered data has been accepted for output by the
+operating system.
+If \fIchannelId\fR is in nonblocking mode then the \fBputs\fR command
+will not block even if the operating system cannot accept the data.
+Instead, Tcl continues to buffer the data and writes it in the
+background as fast as the underlying file or device can accept it.
+The application must use the Tcl event loop for nonblocking output
+to work;  otherwise Tcl never finds out that the file or device is
+ready for more output data.
+It is possible for an arbitrarily large amount of data to be
+buffered for a channel in nonblocking mode, which could consume a
+large amount of memory.
+To avoid wasting memory, nonblocking I/O should normally
+be used in an event-driven fashion with the \fBfileevent\fR command
+(do not invoke \fBputs\fR unless you have recently been notified
+via a file event that the channel is ready for more output data).
+.SH EXAMPLES
+.PP
+Write a short message to the console (or wherever \fBstdout\fR is
+directed):
+.PP
+.CS
+\fBputs\fR "Hello, World!"
+.CE
+.PP
+Print a message in several parts:
+.PP
+.CS
+\fBputs\fR -nonewline "Hello, "
+\fBputs\fR "World!"
+.CE
+.PP
+Print a message to the standard error channel:
+.PP
+.CS
+\fBputs\fR stderr "Hello, World!"
+.CE
+.PP
+Append a log message to a file:

+set timestamp [clock format [clock seconds]]

+.BE
+.SH DESCRIPTION
+.PP
+A \fIregular expression\fR describes strings of characters.
+It's a pattern that matches certain strings and does not match others.
+.SH "DIFFERENT FLAVORS OF REs"
+Regular expressions
+.PQ RE s ,
+as defined by POSIX, come in two flavors: \fIextended\fR REs
+.PQ ERE s
+and \fIbasic\fR REs
+.PQ BRE s .
+EREs are roughly those of the traditional \fIegrep\fR, while BREs are
+roughly those of the traditional \fIed\fR. This implementation adds
+a third flavor, \fIadvanced\fR REs
+.PQ ARE s ,
+basically EREs with some significant extensions.
+.PP
+This manual page primarily describes AREs. BREs mostly exist for
+backward compatibility in some old programs; they will be discussed at
+the end. POSIX EREs are almost an exact subset of AREs. Features of
+AREs that are not present in EREs will be indicated.
+.SH "REGULAR EXPRESSION SYNTAX"
+.PP
+Tcl regular expressions are implemented using the package written by
+Henry Spencer, based on the 1003.2 spec and some (not quite all) of
+the Perl5 extensions (thanks, Henry!). Much of the description of
+regular expressions below is copied verbatim from his manual entry.
+.PP
+An ARE is one or more \fIbranches\fR,
+separated by
+.QW \fB|\fR ,
+matching anything that matches any of the branches.
+.PP
+A branch is zero or more \fIconstraints\fR or \fIquantified atoms\fR,
+concatenated.
+It matches a match for the first, followed by a match for the second, etc;
+an empty branch matches the empty string.
+.SS QUANTIFIERS
+A quantified atom is an \fIatom\fR possibly followed
+by a single \fIquantifier\fR.
+Without a quantifier, it matches a single match for the atom.
+The quantifiers,
+and what a so-quantified atom matches, are:
+.RS 2
+.TP 6
+\fB*\fR
+.
+a sequence of 0 or more matches of the atom
+.TP
+\fB+\fR
+.
+a sequence of 1 or more matches of the atom
+.TP
+\fB?\fR
+.
+a sequence of 0 or 1 matches of the atom
+.TP
+\fB{\fIm\fB}\fR
+.
+a sequence of exactly \fIm\fR matches of the atom
+.TP
+\fB{\fIm\fB,}\fR
+.
+a sequence of \fIm\fR or more matches of the atom
+.TP
+\fB{\fIm\fB,\fIn\fB}\fR
+.
+a sequence of \fIm\fR through \fIn\fR (inclusive) matches of the atom;
+\fIm\fR may not exceed \fIn\fR
+.TP
+\fB*?  +?  ??  {\fIm\fB}?  {\fIm\fB,}?  {\fIm\fB,\fIn\fB}?\fR
+.
+\fInon-greedy\fR quantifiers, which match the same possibilities,
+but prefer the smallest number rather than the largest number
+of matches (see \fBMATCHING\fR)
+.RE
+.PP
+The forms using \fB{\fR and \fB}\fR are known as \fIbound\fRs. The
+numbers \fIm\fR and \fIn\fR are unsigned decimal integers with
+permissible values from 0 to 255 inclusive.
+.SS ATOMS
+An atom is one of:
+.RS 2
+.IP \fB(\fIre\fB)\fR 6
+matches a match for \fIre\fR (\fIre\fR is any regular expression) with
+the match noted for possible reporting
+.IP \fB(?:\fIre\fB)\fR
+as previous, but does no reporting (a
+.QW non-capturing
+set of parentheses)
+.IP \fB()\fR
+matches an empty string, noted for possible reporting
+.IP \fB(?:)\fR
+matches an empty string, without reporting
+.IP \fB[\fIchars\fB]\fR
+a \fIbracket expression\fR, matching any one of the \fIchars\fR (see
+\fBBRACKET EXPRESSIONS\fR for more detail)
+.IP \fB.\fR
+matches any single character
+.IP \fB\e\fIk\fR
+matches the non-alphanumeric character \fIk\fR
+taken as an ordinary character, e.g. \fB\e\e\fR matches a backslash
+character
+.IP \fB\e\fIc\fR
+where \fIc\fR is alphanumeric (possibly followed by other characters),
+an \fIescape\fR (AREs only), see \fBESCAPES\fR below
+.IP \fB{\fR
+when followed by a character other than a digit, matches the
+left-brace character
+.QW \fB{\fR ;
+when followed by a digit, it is the beginning of a \fIbound\fR (see above)
+.IP \fIx\fR
+where \fIx\fR is a single character with no other significance,
+matches that character.
+.RE
+.SS CONSTRAINTS
+A \fIconstraint\fR matches an empty string when specific conditions
+are met. A constraint may not be followed by a quantifier. The
+simple constraints are as follows; some more constraints are described
+later, under \fBESCAPES\fR.
+.RS 2
+.TP 8
+\fB^\fR
+.
+matches at the beginning of a line
+.TP
+\fB$\fR
+.

+.TP
+\fB(?=\fIre\fB)\fR

+\fIpositive lookahead\fR (AREs only), matches at any point where a
+substring matching \fIre\fR begins
+.TP
+\fB(?!\fIre\fB)\fR
+.
+\fInegative lookahead\fR (AREs only), matches at any point where no
+substring matching \fIre\fR begins
+.RE
+.PP
+The lookahead constraints may not contain back references (see later),
+and all parentheses within them are considered non-capturing.
+.PP
+An RE may not end with
+.QW \fB\e\fR .
+.SH "BRACKET EXPRESSIONS"
+A \fIbracket expression\fR is a list of characters enclosed in
+.QW \fB[\|]\fR .
+It normally matches any single character from the list
+(but see below). If the list begins with
+.QW \fB^\fR ,
+it matches any single character (but see below) \fInot\fR from the
+rest of the list.
+.PP
+If two characters in the list are separated by
+.QW \fB\-\fR ,
+this is shorthand for the full \fIrange\fR of characters between those two
+(inclusive) in the collating sequence, e.g.
+.QW \fB[0\-9]\fR
+in Unicode matches any conventional decimal digit. Two ranges may not share an
+endpoint, so e.g.
+.QW \fBa\-c\-e\fR
+is illegal. Ranges in Tcl always use the
+Unicode collating sequence, but other programs may use other collating
+sequences and this can be a source of incompatibility between programs.
+.PP
+To include a literal \fB]\fR or \fB\-\fR in the list, the simplest
+method is to enclose it in \fB[.\fR and \fB.]\fR to make it a
+collating element (see below). Alternatively, make it the first
+character (following a possible
+.QW \fB^\fR ),
+or (AREs only) precede it with
+.QW \fB\e\fR .
+Alternatively, for
+.QW \fB\-\fR ,
+make it the last character, or the second endpoint of a range. To use
+a literal \fB\-\fR as the first endpoint of a range, make it a
+collating element or (AREs only) precede it with
+.QW \fB\e\fR .
+With the exception of
+these, some combinations using \fB[\fR (see next paragraphs), and
+escapes, all other special characters lose their special significance
+within a bracket expression.
+.SS "CHARACTER CLASSES"
+Within a bracket expression, the name of a \fIcharacter class\fR
+enclosed in \fB[:\fR and \fB:]\fR stands for the list of all
+characters (not all collating elements!) belonging to that class.
+Standard character classes are:
+.IP \fBalpha\fR 8
+A letter.
+.IP \fBupper\fR 8
+An upper-case letter.
+.IP \fBlower\fR 8
+A lower-case letter.
+.IP \fBdigit\fR 8
+A decimal digit.
+.IP \fBxdigit\fR 8
+A hexadecimal digit.
+.IP \fBalnum\fR 8
+An alphanumeric (letter or digit).
+.IP \fBprint\fR 8
+A "printable" (same as graph, except also including space).
+.IP \fBblank\fR 8
+A space or tab character.
+.IP \fBspace\fR 8
+A character producing white space in displayed text.
+.IP \fBpunct\fR 8
+A punctuation character.
+.IP \fBgraph\fR 8
+A character with a visible representation (includes both \fBalnum\fR
+and \fBpunct\fR).
+.IP \fBcntrl\fR 8
+A control character.
+.PP
+A locale may provide others. A character class may not be used as an endpoint
+of a range.
+.RS
+.PP
+(\fINote:\fR the current Tcl implementation has only one locale, the Unicode
+locale, which supports exactly the above classes.)
+.RE
+.SS "BRACKETED CONSTRAINTS"
+There are two special cases of bracket expressions: the bracket
+expressions
+.QW \fB[[:<:]]\fR
+and
+.QW \fB[[:>:]]\fR
+are constraints, matching empty strings at the beginning and end of a word
+respectively.
+.\" note, discussion of escapes below references this definition of word
+A word is defined as a sequence of word characters that is neither preceded
+nor followed by word characters. A word character is an \fIalnum\fR character
+or an underscore
+.PQ \fB_\fR "" .
+These special bracket expressions are deprecated; users of AREs should use
+constraint escapes instead (see below).
+.SS "COLLATING ELEMENTS"
+Within a bracket expression, a collating element (a character, a
+multi-character sequence that collates as if it were a single
+character, or a collating-sequence name for either) enclosed in
+\fB[.\fR and \fB.]\fR stands for the sequence of characters of that
+collating element. The sequence is a single element of the bracket
+expression's list. A bracket expression in a locale that has
+multi-character collating elements can thus match more than one
+character. So (insidiously), a bracket expression that starts with
+\fB^\fR can match multi-character collating elements even if none of
+them appear in the bracket expression!
+.RS
+.PP
+(\fINote:\fR Tcl has no multi-character collating elements. This information
+is only for illustration.)
+.RE
+.PP
+For example, assume the collating sequence includes a \fBch\fR multi-character
+collating element. Then the RE
+.QW \fB[[.ch.]]*c\fR
+(zero or more
+.QW \fBch\fRs
+followed by
+.QW \fBc\fR )
+matches the first five characters of
+.QW \fBchchcc\fR .
+Also, the RE
+.QW \fB[^c]b\fR
+matches all of
+.QW \fBchb\fR
+(because
+.QW \fB[^c]\fR
+matches the multi-character
+.QW \fBch\fR ).
+.SS "EQUIVALENCE CLASSES"
+Within a bracket expression, a collating element enclosed in \fB[=\fR
+and \fB=]\fR is an equivalence class, standing for the sequences of
+characters of all collating elements equivalent to that one, including
+itself. (If there are no other equivalent collating elements, the
+treatment is as if the enclosing delimiters were
+.QW \fB[.\fR \&
+and
+.QW \fB.]\fR .)
+For example, if \fBo\fR and \fB\*(qo\fR are the members of an
+equivalence class, then
+.QW \fB[[=o=]]\fR ,
+.QW \fB[[=\*(qo=]]\fR ,
+and
+.QW \fB[o\*(qo]\fR \&
+are all synonymous. An equivalence class may not be an endpoint of a range.
+.RS
+.PP
+(\fINote:\fR Tcl implements only the Unicode locale. It does not define any
+equivalence classes. The examples above are just illustrations.)
+.RE
+.SH ESCAPES
+Escapes (AREs only), which begin with a \fB\e\fR followed by an
+alphanumeric character, come in several varieties: character entry,
+class shorthands, constraint escapes, and back references. A \fB\e\fR
+followed by an alphanumeric character but not constituting a valid
+escape is illegal in AREs. In EREs, there are no escapes: outside a
+bracket expression, a \fB\e\fR followed by an alphanumeric character
+merely stands for that character as an ordinary character, and inside
+a bracket expression, \fB\e\fR is an ordinary character. (The latter
+is the one actual incompatibility between EREs and AREs.)
+.SS "CHARACTER-ENTRY ESCAPES"
+Character-entry escapes (AREs only) exist to make it easier to specify
+non-printing and otherwise inconvenient characters in REs:
+.RS 2
+.TP 5
+\fB\ea\fR

+.PP
+The character-entry escapes are always taken as ordinary characters.
+For example, \fB\e135\fR is \fB]\fR in Unicode, but \fB\e135\fR does
+not terminate a bracket expression. Beware, however, that some
+applications (e.g., C compilers and the Tcl interpreter if the regular
+expression is not quoted with braces) interpret such sequences
+themselves before the regular-expression package gets to see them,
+which may require doubling (quadrupling, etc.) the
+.QW \fB\e\fR .
+.SS "CLASS-SHORTHAND ESCAPES"
+Class-shorthand escapes (AREs only) provide shorthands for certain
+commonly-used character classes:
+.RS 2
+.TP 10
+\fB\ed\fR
+.
+\fB[[:digit:]]\fR

+lose their outer brackets, and
+.QW \fB\eD\fR ,
+.QW \fB\eS\fR ,
+and
+.QW \fB\eW\fR \&
+are illegal. (So, for example,
+.QW \fB[a-c\ed]\fR
+is equivalent to
+.QW \fB[a-c[:digit:]]\fR .
+Also,
+.QW \fB[a-c\eD]\fR ,
+which is equivalent to
+.QW \fB[a-c^[:digit:]]\fR ,
+is illegal.)
+.SS "CONSTRAINT ESCAPES"
+A constraint escape (AREs only) is a constraint, matching the empty
+string if specific conditions are met, written as an escape:
+.RS 2
+.TP 6
+\fB\eA\fR
+.
+matches only at the beginning of the string (see \fBMATCHING\fR,

+.TP
+\fB\eM\fR

+\fB\ey\fR

+.TP
+\fB\eY\fR
+.
+matches only at a point that is not the beginning or end of a word
+.TP
+\fB\eZ\fR

+how this differs from
+.QW \fB$\fR )
+.TP
+\fB\e\fIm\fR
+.
+(where \fIm\fR is a nonzero digit) a \fIback reference\fR, see below
+.TP
+\fB\e\fImnn\fR
+.
+(where \fIm\fR is a nonzero digit, and \fInn\fR is some more digits,
+and the decimal value \fImnn\fR is not greater than the number of
+closing capturing parentheses seen so far) a \fIback reference\fR, see
+below
+.RE
+.PP
+A word is defined as in the specification of
+.QW \fB[[:<:]]\fR
+and
+.QW \fB[[:>:]]\fR
+above. Constraint escapes are illegal within bracket expressions.
+.SS "BACK REFERENCES"
+A back reference (AREs only) matches the same string matched by the
+parenthesized subexpression specified by the number, so that (e.g.)
+.QW \fB([bc])\e1\fR
+matches
+.QW \fBbb\fR
+or
+.QW \fBcc\fR
+but not
+.QW \fBbc\fR .
+The subexpression must entirely precede the back reference in the RE.
+Subexpressions are numbered in the order of their leading parentheses.
+Non-capturing parentheses do not define subexpressions.
+.PP
+There is an inherent historical ambiguity between octal
+character-entry escapes and back references, which is resolved by
+heuristics, as hinted at above. A leading zero always indicates an
+octal escape. A single non-zero digit, not followed by another digit,
+is always taken as a back reference. A multi-digit sequence not
+starting with a zero is taken as a back reference if it comes after a
+suitable subexpression (i.e. the number is in the legal range for a
+back reference), and otherwise is taken as octal.
+.SH "METASYNTAX"
+In addition to the main syntax described above, there are some special
+forms and miscellaneous syntactic facilities available.
+.PP
+Normally the flavor of RE being used is specified by
+application-dependent means. However, this can be overridden by a
+\fIdirector\fR. If an RE of any flavor begins with
+.QW \fB***:\fR ,
+the rest of the RE is an ARE. If an RE of any flavor begins with
+.QW \fB***=\fR ,
+the rest of the RE is taken to be a literal string, with
+all characters considered ordinary characters.
+.PP
+An ARE may begin with \fIembedded options\fR: a sequence
+\fB(?\fIxyz\fB)\fR (where \fIxyz\fR is one or more alphabetic
+characters) specifies options affecting the rest of the RE. These
+supplement, and can override, any options specified by the
+application. The available option letters are:
+.RS 2
+.TP 3
+\fBb\fR

+.RE
+.PP
+Embedded options take effect at the \fB)\fR terminating the sequence.
+They are available only at the start of an ARE, and may not be used
+later within it.
+.PP
+In addition to the usual (\fItight\fR) RE syntax, in which all
+characters are significant, there is an \fIexpanded\fR syntax,
+available in all flavors of RE with the \fB\-expanded\fR switch, or in
+AREs with the embedded x option. In the expanded syntax, white-space
+characters are ignored and all characters between a \fB#\fR and the
+following newline (or the end of the RE) are ignored, permitting
+paragraphing and commenting a complex RE. There are three exceptions
+to that basic rule:
+.IP \(bu 3
+a white-space character or
+.QW \fB#\fR
+preceded by
+.QW \fB\e\fR
+is retained
+.IP \(bu 3
+white space or
+.QW \fB#\fR
+within a bracket expression is retained
+.IP \(bu 3
+white space and comments are illegal within multi-character symbols
+like the ARE
+.QW \fB(?:\fR
+or the BRE
+.QW \fB\e(\fR
+.PP
+Expanded-syntax white-space characters are blank, tab, newline, and
+any character that belongs to the \fIspace\fR character class.
+.PP
+Finally, in an ARE, outside bracket expressions, the sequence
+.QW \fB(?#\fIttt\fB)\fR
+(where \fIttt\fR is any text not containing a
+.QW \fB)\fR )
+is a comment, completely ignored. Again, this is not
+allowed between the characters of multi-character symbols like
+.QW \fB(?:\fR .
+Such comments are more a historical artifact than a useful facility,
+and their use is deprecated; use the expanded syntax instead.
+.PP
+\fINone\fR of these metasyntax extensions is available if the
+application (or an initial
+.QW \fB***=\fR
+director) has specified that the
+user's input be treated as a literal string rather than as an RE.
+.SH MATCHING
+In the event that an RE could match more than one substring of a given
+string, the RE matches the one starting earliest in the string. If
+the RE could match more than one substring starting at that point, its
+choice is determined by its \fIpreference\fR: either the longest
+substring, or the shortest.
+.PP
+Most atoms, and all constraints, have no preference. A parenthesized
+RE has the same preference (possibly none) as the RE. A quantified
+atom with quantifier \fB{\fIm\fB}\fR or \fB{\fIm\fB}?\fR has the same
+preference (possibly none) as the atom itself. A quantified atom with
+other normal quantifiers (including \fB{\fIm\fB,\fIn\fB}\fR with
+\fIm\fR equal to \fIn\fR) prefers longest match. A quantified atom
+with other non-greedy quantifiers (including \fB{\fIm\fB,\fIn\fB}?\fR
+with \fIm\fR equal to \fIn\fR) prefers shortest match. A branch has
+the same preference as the first quantified atom in it which has a
+preference. An RE consisting of two or more branches connected by the
+\fB|\fR operator prefers longest match.
+.PP
+Subject to the constraints imposed by the rules for matching the whole
+RE, subexpressions also match the longest or shortest possible
+substrings, based on their preferences, with subexpressions starting
+earlier in the RE taking priority over ones starting later. Note that
+outer subexpressions thus take priority over their component
+subexpressions.
+.PP
+Note that the quantifiers \fB{1,1}\fR and \fB{1,1}?\fR can be used to
+force longest and shortest preference, respectively, on a
+subexpression or a whole RE.
+.PP
+Match lengths are measured in characters, not collating elements. An
+empty string is considered longer than no match at all. For example,
+.QW \fBbb*\fR
+matches the three middle characters of
+.QW \fBabbbc\fR ,
+.QW \fB(week|wee)(night|knights)\fR
+matches all ten characters of
+.QW \fBweeknights\fR ,
+when
+.QW \fB(.*).*\fR
+is matched against
+.QW \fBabc\fR
+the parenthesized subexpression matches all three characters, and when
+.QW \fB(a*)*\fR
+is matched against
+.QW \fBbc\fR
+both the whole RE and the parenthesized subexpression match an empty string.
+.PP
+If case-independent matching is specified, the effect is much as if
+all case distinctions had vanished from the alphabet. When an
+alphabetic that exists in multiple cases appears as an ordinary
+character outside a bracket expression, it is effectively transformed
+into a bracket expression containing both cases, so that \fBx\fR
+becomes
+.QW \fB[xX]\fR .
+When it appears inside a bracket expression,
+all case counterparts of it are added to the bracket expression, so
+that
+.QW \fB[x]\fR
+becomes
+.QW \fB[xX]\fR
+and
+.QW \fB[^x]\fR
+becomes
+.QW \fB[^xX]\fR .
+.PP
+If newline-sensitive matching is specified, \fB.\fR and bracket
+expressions using \fB^\fR will never match the newline character (so
+that matches will never cross newlines unless the RE explicitly
+arranges it) and \fB^\fR and \fB$\fR will match the empty string after
+and before a newline respectively, in addition to matching at
+beginning and end of string respectively. ARE \fB\eA\fR and \fB\eZ\fR
+continue to match beginning or end of string \fIonly\fR.
+.PP
+If partial newline-sensitive matching is specified, this affects
+\fB.\fR and bracket expressions as with newline-sensitive matching,
+but not \fB^\fR and \fB$\fR.
+.PP
+If inverse partial newline-sensitive matching is specified, this
+affects \fB^\fR and \fB$\fR as with newline-sensitive matching, but
+not \fB.\fR and bracket expressions. This is not very useful but is
+provided for symmetry.
+.SH "LIMITS AND COMPATIBILITY"
+No particular limit is imposed on the length of REs. Programs
+intended to be highly portable should not employ REs longer than 256
+bytes, as a POSIX-compliant implementation can refuse to accept such
+REs.
+.PP
+The only feature of AREs that is actually incompatible with POSIX EREs
+is that \fB\e\fR does not lose its special significance inside bracket
+expressions. All other ARE features use syntax which is illegal or
+has undefined or unspecified effects in POSIX EREs; the \fB***\fR
+syntax of directors likewise is outside the POSIX syntax for both BREs
+and EREs.
+.PP
+Many of the ARE extensions are borrowed from Perl, but some have been
+changed to clean them up, and a few Perl extensions are not present.
+Incompatibilities of note include
+.QW \fB\eb\fR ,
+.QW \fB\eB\fR ,
+the lack of special treatment for a trailing newline, the addition of
+complemented bracket expressions to the things affected by
+newline-sensitive matching, the restrictions on parentheses and back
+references in lookahead constraints, and the longest/shortest-match
+(rather than first-match) matching semantics.
+.PP
+The matching rules for REs containing both normal and non-greedy
+quantifiers have changed since early beta-test versions of this
+package. (The new rules are much simpler and cleaner, but do not work
+as hard at guessing the user's real intentions.)
+.PP
+Henry Spencer's original 1986 \fIregexp\fR package, still in
+widespread use (e.g., in pre-8.1 releases of Tcl), implemented an
+early version of today's EREs. There are four incompatibilities
+between \fIregexp\fR's near-EREs
+.PQ RREs " for short"
+and AREs. In roughly increasing order of significance:
+.IP \(bu 3
+In AREs, \fB\e\fR followed by an alphanumeric character is either an
+escape or an error, while in RREs, it was just another way of writing
+the alphanumeric. This should not be a problem because there was no
+reason to write such a sequence in RREs.
+.IP \(bu 3
+\fB{\fR followed by a digit in an ARE is the beginning of a bound,
+while in RREs, \fB{\fR was always an ordinary character. Such
+sequences should be rare, and will often result in an error because
+following characters will not look like a valid bound.
+.IP \(bu 3
+In AREs, \fB\e\fR remains a special character within
+.QW \fB[\|]\fR ,
+so a literal \fB\e\fR within \fB[\|]\fR must be written
+.QW \fB\e\e\fR .
+\fB\e\e\fR also gives a literal \fB\e\fR within \fB[\|]\fR in RREs,
+but only truly paranoid programmers routinely doubled the backslash.
+.IP \(bu 3
+AREs report the longest/shortest match for the RE, rather than the
+first found in a specified search order. This may affect some RREs
+which were written in the expectation that the first match would be
+reported. (The careful crafting of RREs to optimize the search order
+for fast matching is obsolete (AREs examine all possible matches in
+parallel, and their performance is largely insensitive to their
+complexity) but cases where the search order was exploited to
+deliberately find a match which was \fInot\fR the longest/shortest
+will need rewriting.)
+.SH "BASIC REGULAR EXPRESSIONS"
+BREs differ from EREs in several respects.
+.QW \fB|\fR ,
+.QW \fB+\fR ,
+and \fB?\fR are ordinary characters and there is no equivalent for their
+functionality. The delimiters for bounds are \fB\e{\fR and
+.QW \fB\e}\fR ,
+with \fB{\fR and \fB}\fR by themselves ordinary characters. The
+parentheses for nested subexpressions are \fB\e(\fR and
+.QW \fB\e)\fR ,
+with \fB(\fR and \fB)\fR by themselves ordinary
+characters. \fB^\fR is an ordinary character except at the beginning
+of the RE or the beginning of a parenthesized subexpression, \fB$\fR
+is an ordinary character except at the end of the RE or the end of a
+parenthesized subexpression, and \fB*\fR is an ordinary character if
+it appears at the beginning of the RE or the beginning of a
+parenthesized subexpression (after a possible leading
+.QW \fB^\fR ).
+Finally, single-digit back references are available, and \fB\e<\fR and
+\fB\e>\fR are synonyms for
+.QW \fB[[:<:]]\fR
+and
+.QW \fB[[:>:]]\fR
+respectively; no other escapes are available.

+.SH NAME
+read \- Read from a channel
+.SH SYNOPSIS
+\fBread \fR?\fB\-nonewline\fR? \fIchannelId\fR
+.sp
+\fBread \fIchannelId numChars\fR
+.BE
+.SH DESCRIPTION
+.PP
+In the first form, the \fBread\fR command reads all of the data from
+\fIchannelId\fR up to the end of the file.  If the \fB\-nonewline\fR
+switch is specified then the last character of the file is discarded
+if it is a newline.  In the second form, the extra argument specifies
+how many characters to read.  Exactly that many characters will be
+read and returned, unless there are fewer than \fInumChars\fR left in
+the file; in this case all the remaining characters are returned.  If
+the channel is configured to use a multi-byte encoding, then the
+number of characters read may not be the same as the number of bytes
+read.
+.PP
+\fIChannelId\fR must be an identifier for an open channel such as the
+Tcl standard input channel (\fBstdin\fR), the return value from an
+invocation of \fBopen\fR or \fBsocket\fR, or the result of a channel
+creation command provided by a Tcl extension. The channel must have
+been opened for input.
+.PP
+If \fIchannelId\fR is in nonblocking mode, the command may not read as
+many characters as requested: once all available input has been read,
+the command will return the data that is available rather than
+blocking for more input.  If the channel is configured to use a
+multi-byte encoding, then there may actually be some bytes remaining
+in the internal buffers that do not form a complete character.  These
+bytes will not be returned until a complete character is available or
+end-of-file is reached.  The \fB\-nonewline\fR switch is ignored if
+the command returns before reaching the end of the file.
+.PP
+\fBRead\fR translates end-of-line sequences in the input into
+newline characters according to the \fB\-translation\fR option
+for the channel.
+See the \fBfconfigure\fR manual entry for a discussion on ways in
+which \fBfconfigure\fR will alter input.
+.SH "USE WITH SERIAL PORTS"
+'\" Note:  this advice actually applies to many versions of Tcl
+.PP
+For most applications a channel connected to a serial port should be
+configured to be nonblocking: \fBfconfigure\fI channelId \fB\-blocking
+\fI0\fR.  Then \fBread\fR behaves much like described above.  Care
+must be taken when using \fBread\fR on blocking serial ports:
+.TP
+\fBread \fIchannelId numChars\fR 
+.
+In this form \fBread\fR blocks until \fInumChars\fR have been received
+from the serial port.
+.TP
+\fBread \fIchannelId\fR 
+.
+In this form \fBread\fR blocks until the reception of the end-of-file
+character, see \fBfconfigure\fR \fB\-eofchar\fR. If there no end-of-file
+character has been configured for the channel, then \fBread\fR will
+block forever.
+.SH "EXAMPLE"
+.PP
+This example code reads a file all at once, and splits it into a list,
+with each line in the file corresponding to an element in the list:
+.PP

+.SH NAME
+refchan \- command handler API of reflected channels
+.SH SYNOPSIS
+\fBcmdPrefix \fIoption\fR ?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+The Tcl-level handler for a reflected channel has to be a command with
+subcommands (termed an \fIensemble\fR, as it is a command such as that
+created by \fBnamespace ensemble\fR \fBcreate\fR, though the implementation
+of handlers for reflected channel \fIis not\fR tied to \fBnamespace
+ensemble\fRs in any way; see \fBEXAMPLE\fR below for how to build an
+\fBoo::class\fR that supports the API). Note that \fIcmdPrefix\fR is whatever was
+specified in the call to \fBchan create\fR, and may consist of
+multiple arguments; this will be expanded to multiple words in place
+of the prefix.
+.PP
+Of all the possible subcommands, the handler \fImust\fR support
+\fBinitialize\fR, \fBfinalize\fR, and \fBwatch\fR. Support for the
+other subcommands is optional.
+.SS "MANDATORY SUBCOMMANDS"
+.TP
+\fIcmdPrefix \fBinitialize \fIchannelId mode\fR
+.
+An invocation of this subcommand will be the first call the
+\fIcmdPrefix\fR will receive for the specified new \fIchannelId\fR. It
+is the responsibility of this subcommand to set up any internal data
+structures required to keep track of the channel and its state.
+.RS
+.PP
+The return value of the method has to be a list containing the names
+of all subcommands supported by the \fIcmdPrefix\fR. This also tells
+the Tcl core which version of the API for reflected channels is used by
+this command handler.
+.PP
+Any error thrown by the method will abort the creation of the channel
+and no channel will be created. The thrown error will appear as error
+thrown by \fBchan create\fR. Any exception other than an \fBerror\fR
+(e.g.,\ \fBbreak\fR, etc.) is treated as (and converted to) an error.
+.PP
+\fBNote:\fR If the creation of the channel was aborted due to failures
+here, then the \fBfinalize\fR subcommand will not be called.
+.PP
+The \fImode\fR argument tells the handler whether the channel was
+opened for reading, writing, or both. It is a list containing any of
+the strings \fBread\fR or \fBwrite\fR. The list will always
+contain at least one element.
+.PP
+The subcommand must throw an error if the chosen mode is not
+supported by the \fIcmdPrefix\fR.
+.RE
+.TP
+\fIcmdPrefix \fBfinalize \fIchannelId\fR
+.
+An invocation of this subcommand will be the last call the
+\fIcmdPrefix\fR will receive for the specified \fIchannelId\fR. It will
+be generated just before the destruction of the data structures of the
+channel held by the Tcl core. The command handler \fImust not\fR
+access the \fIchannelId\fR anymore in no way. Upon this subcommand being
+called, any internal resources allocated to this channel must be
+cleaned up.
+.RS
+.PP
+The return value of this subcommand is ignored.
+.PP
+If the subcommand throws an error the command which caused its
+invocation (usually \fBchan close\fR) will appear to have thrown this
+error. Any exception beyond \fBerror\fR (e.g.,\ \fBbreak\fR, etc.) is
+treated as (and converted to) an error.
+.PP
+This subcommand is not invoked if the creation of the channel was
+aborted during \fBinitialize\fR (See above).
+.RE
+.TP
+\fIcmdPrefix \fBwatch \fIchannelId eventspec\fR
+.
+This subcommand notifies the \fIcmdPrefix\fR that the specified
+\fIchannelId\fR is interested in the events listed in the
+\fIeventspec\fR. This argument is a list containing any of \fBread\fR
+and \fBwrite\fR. The list may be empty, which signals that the
+channel does not wish to be notified of any events. In that situation,
+the handler should disable event generation completely.
+.RS
+.PP
+\fBWarning:\fR Any return value of the subcommand is ignored. This
+includes all errors thrown by the subcommand, \fBbreak\fR, \fBcontinue\fR, and
+custom return codes.
+.PP
+This subcommand interacts with \fBchan postevent\fR. Trying to post an
+event which was not listed in the last call to \fBwatch\fR will cause
+\fBchan postevent\fR to throw an error.
+.RE
+.SS "OPTIONAL SUBCOMMANDS"
+.TP
+\fIcmdPrefix \fBread \fIchannelId count\fR
+.
+This \fIoptional\fR subcommand is called when the user requests data from the
+channel \fIchannelId\fR. \fIcount\fR specifies how many \fIbytes\fR have been
+requested. If the subcommand is not supported then it is not possible to read
+from the channel handled by the command.
+.RS
+.PP
+The return value of this subcommand is taken as the requested data
+\fIbytes\fR. If the returned data contains more bytes than requested,
+an error will be signaled and later thrown by the command which
+performed the read (usually \fBgets\fR or \fBread\fR). However,
+returning fewer bytes than requested is acceptable.
+.PP
+Note that returning nothing (0 bytes) is a signal to the higher layers
+that \fBEOF\fR has been reached on the channel. To signal that the
+channel is out of data right now, but has not yet reached \fBEOF\fR,
+it is necessary to throw the error "EAGAIN", i.e. to either
+.PP
+.CS
+return -code error EAGAIN
+.CE
+or
+.CS
+error EAGAIN
+.CE
+.PP
+For extensibility any error whose value is a negative integer number
+will cause the higher layers to set the C-level variable "\fBerrno\fR"
+to the absolute value of this number, signaling a system error.
+However, note that the exact mapping between these error numbers and
+their meanings is operating system dependent.
+.PP
+For example, while on Linux both
+.PP
+.CS
+return -code error -11
+.CE
+and
+.CS
+error -11
+.CE
+.PP
+are equivalent to the examples above, using the more readable string "EAGAIN",
+this is not true for BSD, where the equivalent number is -35.
+.PP
+The symbolic string however is the same across systems, and internally
+translated to the correct number. No other error value has such a mapping
+to a symbolic string.
+.PP
+If the subcommand throws any other error, the command which caused its
+invocation (usually \fBgets\fR, or \fBread\fR) will appear to have
+thrown this error. Any exception beyond \fBerror\fR, (e.g.,\ \fBbreak\fR,
+etc.) is treated as and converted to an error.
+.RE
+.TP
+\fIcmdPrefix \fBwrite \fIchannelId data\fR
+.
+This \fIoptional\fR subcommand is called when the user writes data to
+the channel \fIchannelId\fR. The \fIdata\fR argument contains \fIbytes\fR, not
+characters. Any type of transformation (EOL, encoding) configured for
+the channel has already been applied at this point. If this subcommand
+is not supported then it is not possible to write to the channel
+handled by the command.
+.RS
+.PP
+The return value of the subcommand is taken as the number of bytes
+written by the channel. Anything non-numeric will cause an error to be
+signaled and later thrown by the command which performed the write. A
+negative value implies that the write failed. Returning a value
+greater than the number of bytes given to the handler, or zero, is
+forbidden and will cause the Tcl core to throw an error.
+.PP
+To signal that the channel is not able to accept data for writing
+right now, it is necessary to throw the error "EAGAIN", i.e. to either
+.PP
+.CS
+return -code error EAGAIN
+.CE
+or
+.CS
+error EAGAIN
+.CE
+.PP
+For extensibility any error whose value is a negative integer number
+will cause the higher layers to set the C-level variable "\fBerrno\fR"
+to the absolute value of this number, signaling a system error.
+However, note that the exact mapping between these error numbers and
+their meanings is operating system dependent.
+.PP
+For example, while on Linux both
+.PP
+.CS
+return -code error -11
+.CE
+and

+error -11

+.PP
+The symbolic string however is the same across systems, and internally
+translated to the correct number. No other error value has such a mapping
+to a symbolic string.
+.PP
+If the subcommand throws any other error the command which caused its
+invocation (usually \fBputs\fR) will appear to have thrown this error.
+Any exception beyond \fBerror\fR (e.g.,\ \fBbreak\fR, etc.) is treated
+as and converted to an error.
+.RE
+.TP
+\fIcmdPrefix \fBseek \fIchannelId offset base\fR
+.
+This \fIoptional\fR subcommand is responsible for the handling of
+\fBchan seek\fR and \fBchan tell\fR requests on the channel
+\fIchannelId\fR. If it is not supported then seeking will not be possible for
+the channel.
+.RS
+.PP
+The \fIbase\fR argument is the same as the equivalent argument of the
+builtin \fBchan seek\fR, namely:
+.TP 10
+\fBstart\fR
+.
+Seeking is relative to the beginning of the channel.
+.TP 10
+\fBcurrent\fR
+.
+Seeking is relative to the current seek position.
+.TP 10
+\fBend\fR
+.
+Seeking is relative to the end of the channel.
+.PP
+The \fIoffset\fR is an integer number specifying the amount of
+\fBbytes\fR to seek forward or backward. A positive number should seek
+forward, and a negative number should seek backward.
+A channel may provide only limited seeking. For example sockets can
+seek forward, but not backward.
+.PP
+The return value of the subcommand is taken as the (new) location of
+the channel, counted from the start. This has to be an integer number
+greater than or equal to zero.
+If the subcommand throws an error the command which caused its
+invocation (usually \fBchan seek\fR, or \fBchan tell\fR) will appear to have
+thrown this error. Any exception beyond \fBerror\fR (e.g.,\ \fBbreak\fR,
+etc.) is treated as and converted to an error.
+.PP
+The offset/base combination of 0/\fBcurrent\fR signals a \fBchan tell\fR
+request, i.e.,\ seek nothing relative to the current location, making
+the new location identical to the current one, which is then returned.
+.RE
+.TP
+\fIcmdPrefix \fBconfigure \fIchannelId option value\fR
+.
+This \fIoptional\fR subcommand is for setting the type-specific options of
+channel \fIchannelId\fR. The \fIoption\fR argument indicates the option to be
+written, and the \fIvalue\fR argument indicates the value to set the option to.
+.RS
+.PP
+This subcommand will never try to update more than one option at a
+time; that is behavior implemented in the Tcl channel core.
+.PP
+The return value of the subcommand is ignored.
+.PP
+If the subcommand throws an error the command which performed the
+(re)configuration or query (usually \fBfconfigure\fR or
+\fBchan configure\fR) will appear to have thrown this error. Any exception
+beyond \fBerror\fR (e.g.,\ \fBbreak\fR, etc.) is treated as and
+converted to an error.
+.RE
+.TP
+\fIcmdPrefix \fBcget \fIchannelId option\fR
+.
+This \fIoptional\fR subcommand is used when reading a single type-specific
+option of channel \fIchannelId\fR. If this subcommand is supported then the
+subcommand \fBcgetall\fR must be supported as well.
+.RS
+.PP
+The subcommand should return the value of the specified \fIoption\fR.
+.PP
+If the subcommand throws an error, the command which performed the
+(re)configuration or query (usually \fBfconfigure\fR or \fBchan configure\fR)
+will appear to have thrown this error. Any exception beyond \fIerror\fR
+(e.g.,\ \fBbreak\fR, etc.) is treated as and converted to an error.
+.RE
+.TP
+\fIcmdPrefix \fBcgetall \fIchannelId\fR
+.
+This \fIoptional\fR subcommand is used for reading all type-specific options
+of channel \fIchannelId\fR. If this subcommand is supported then the
+subcommand \fBcget\fR has to be supported as well.
+.RS
+.PP
+The subcommand should return a list of all options and their values.
+This list must have an even number of elements.
+.PP
+If the subcommand throws an error the command which performed the
+(re)configuration or query (usually \fBfconfigure\fR or \fBchan configure\fR)
+will appear to have thrown this error. Any exception beyond \fBerror\fR
+(e.g.,\ \fBbreak\fR, etc.) is treated as and converted to an error.
+.RE
+.TP
+\fIcmdPrefix \fBblocking \fIchannelId mode\fR
+.
+This \fIoptional\fR subcommand handles changes to the blocking mode of the
+channel \fIchannelId\fR. The \fImode\fR is a boolean flag. A true value means
+that the channel has to be set to blocking, and a false value means that the
+channel should be non-blocking.
+.RS
+.PP
+The return value of the subcommand is ignored.
+.PP
+If the subcommand throws an error the command which caused its
+invocation (usually \fBfconfigure\fR or \fBchan configure\fR) will appear to
+have thrown this error. Any exception beyond \fBerror\fR (e.g.,\ \fBbreak\fR,
+etc.) is treated as and converted to an error.
+.RE
+.SH NOTES
+Some of the functions supported in channels defined in Tcl's C
+interface are not available to channels reflected to the Tcl level.
+.PP
+The function \fBTcl_DriverGetHandleProc\fR is not supported;
+i.e.,\ reflected channels do not have OS specific handles.
+.PP
+The function \fBTcl_DriverHandlerProc\fR is not supported. This driver
+function is relevant only for stacked channels, i.e.,\ transformations.
+Reflected channels are always base channels, not transformations.
+.PP
+The function \fBTcl_DriverFlushProc\fR is not supported. This is
+because the current generic I/O layer of Tcl does not use this
+function anywhere at all. Therefore support at the Tcl level makes no
+sense either. This may be altered in the future (through extending the
+API defined here and changing its version number) should the function
+be used at some time in the future.

+.SH NAME
+regexp \- Match a regular expression against a string
+.SH SYNOPSIS
+\fBregexp \fR?\fIswitches\fR? \fIexp string \fR?\fImatchVar\fR? ?\fIsubMatchVar subMatchVar ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+Determines whether the regular expression \fIexp\fR matches part or
+all of \fIstring\fR and returns 1 if it does, 0 if it does not, unless
+\fB\-inline\fR is specified (see below).
+(Regular expression matching is described in the \fBre_syntax\fR
+reference page.)
+.PP
+If additional arguments are specified after \fIstring\fR then they
+are treated as the names of variables in which to return
+information about which part(s) of \fIstring\fR matched \fIexp\fR.
+\fIMatchVar\fR will be set to the range of \fIstring\fR that
+matched all of \fIexp\fR.  The first \fIsubMatchVar\fR will contain
+the characters in \fIstring\fR that matched the leftmost parenthesized
+subexpression within \fIexp\fR, the next \fIsubMatchVar\fR will
+contain the characters that matched the next parenthesized
+subexpression to the right in \fIexp\fR, and so on.
+.PP
+If the initial arguments to \fBregexp\fR start with \fB\-\fR then
+they are treated as switches.  The following switches are
+currently supported:
+.TP 15
+\fB\-about\fR
+.
+Instead of attempting to match the regular expression, returns a list
+containing information about the regular expression.  The first
+element of the list is a subexpression count.  The second element is a
+list of property names that describe various attributes of the regular
+expression. This switch is primarily intended for debugging purposes.
+.TP 15
+\fB\-expanded\fR
+.
+Enables use of the expanded regular expression syntax where
+whitespace and comments are ignored.  This is the same as specifying
+the \fB(?x)\fR embedded option (see the \fBre_syntax\fR manual page).
+.TP 15
+\fB\-indices\fR
+.
+Changes what is stored in the \fIsubMatchVar\fRs. 
+Instead of storing the matching characters from \fIstring\fR,
+each variable
+will contain a list of two decimal strings giving the indices
+in \fIstring\fR of the first and last characters in the matching
+range of characters.
+.TP 15
+\fB\-line\fR
+.
+Enables newline-sensitive matching.  By default, newline is a
+completely ordinary character with no special meaning.  With this
+flag,
+.QW [^
+bracket expressions and
+.QW .
+never match newline,
+.QW ^
+matches an empty string after any newline in addition to its normal
+function, and
+.QW $
+matches an empty string before any newline in
+addition to its normal function.  This flag is equivalent to
+specifying both \fB\-linestop\fR and \fB\-lineanchor\fR, or the
+\fB(?n)\fR embedded option (see the \fBre_syntax\fR manual page).
+.TP 15
+\fB\-linestop\fR
+.
+Changes the behavior of
+.QW [^
+bracket expressions and
+.QW .
+so that they
+stop at newlines.  This is the same as specifying the \fB(?p)\fR
+embedded option (see the \fBre_syntax\fR manual page).
+.TP 15
+\fB\-lineanchor\fR
+.
+Changes the behavior of
+.QW ^
+and
+.QW $
+(the
+.QW anchors )
+so they match the
+beginning and end of a line respectively.  This is the same as
+specifying the \fB(?w)\fR embedded option (see the \fBre_syntax\fR
+manual page).
+.TP 15
+\fB\-nocase\fR
+.
+Causes upper-case characters in \fIstring\fR to be treated as
+lower case during the matching process.
+.TP 15
+\fB\-all\fR
+.
+Causes the regular expression to be matched as many times as possible
+in the string, returning the total number of matches found.  If this
+is specified with match variables, they will contain information for
+the last match only.
+.TP 15
+\fB\-inline\fR
+.
+Causes the command to return, as a list, the data that would otherwise
+be placed in match variables.  When using \fB\-inline\fR,
+match variables may not be specified.  If used with \fB\-all\fR, the
+list will be concatenated at each iteration, such that a flat list is
+always returned.  For each match iteration, the command will append the
+overall match data, plus one element for each subexpression in the
+regular expression.  Examples are:
+.RS
+.PP
+.CS
+\fBregexp\fR -inline -- {\ew(\ew)} " inlined "
+      \fI\(-> in n\fR
+\fBregexp\fR -all -inline -- {\ew(\ew)} " inlined "
+      \fI\(-> in n li i ne e\fR
+.CE
+.RE
+.TP 15
+\fB\-start\fR \fIindex\fR
+.
+Specifies a character index offset into the string to start
+matching the regular expression at.  
+The \fIindex\fR value is interpreted in the same manner
+as the \fIindex\fR argument to \fBstring index\fR.
+When using this switch,
+.QW ^
+will not match the beginning of the line, and \eA will still
+match the start of the string at \fIindex\fR.  If \fB\-indices\fR
+is specified, the indices will be indexed starting from the
+absolute beginning of the input string.
+\fIindex\fR will be constrained to the bounds of the input string.
+.TP 15
+\fB\-\|\-\fR
+.
+Marks the end of switches.  The argument following this one will
+be treated as \fIexp\fR even if it starts with a \fB\-\fR.
+.PP
+If there are more \fIsubMatchVar\fRs than parenthesized
+subexpressions within \fIexp\fR, or if a particular subexpression
+in \fIexp\fR does not match the string (e.g. because it was in a
+portion of the expression that was not matched), then the corresponding
+\fIsubMatchVar\fR will be set to
+.QW "\fB\-1 \-1\fR"
+if \fB\-indices\fR has been specified or to an empty string otherwise.
+.SH EXAMPLES
+.PP
+Find the first occurrence of a word starting with \fBfoo\fR in a
+string that is not actually an instance of \fBfoobar\fR, and get the
+letters following it up to the end of the word into a variable:
+.PP
+.CS
+\fBregexp\fR {\emfoo(?!bar\eM)(\ew*)} $string \-> restOfWord
+.CE
+.PP
+Note that the whole matched substring has been placed in the variable
+.QW \fB\->\fR ,
+which is a name chosen to look nice given that we are not
+actually interested in its contents.
+.PP
+Find the index of the word \fBbadger\fR (in any case) within a string
+and store that in the variable \fBlocation\fR:
+.PP
+.CS
+\fBregexp\fR \-indices {(?i)\embadger\eM} $string location
+.CE
+.PP
+This could also be written as a \fIbasic\fR regular expression (as opposed
+to using the default syntax of \fIadvanced\fR regular expressions) match by
+prefixing the expression with a suitable flag:
+.PP
+.CS
+\fBregexp\fR \-indices {(?ib)\e<badger\e>} $string location
+.CE
+.PP
+This counts the number of octal digits in a string:
+.PP
+.CS
+\fBregexp\fR \-all {[0\-7]} $string
+.CE
+.PP
+This lists all words (consisting of all sequences of non-whitespace
+characters) in a string, and is useful as a more powerful version of the
+\fBsplit\fR command:

+\fBsz\fR is assumed.  For more details on the data and type arguments,
+see \fBSUPPORTED TYPES\fR below.
+.TP
+\fBregistry type \fIkeyName valueName\fR

+\fBregistry values \fIkeyName\fR ?\fIpattern\fR?
+.
+If \fIpattern\fR is not specified, returns a list of names of all the
+values of \fIkeyName\fR.  If \fIpattern\fR is specified, only those
+names matching \fIpattern\fR are returned.  Matching is determined
+using the same rules as for \fBstring match\fR.
+.SH "SUPPORTED TYPES"
+Each value under a key in the registry contains some data of a
+particular type in a type-specific representation.  The \fBregistry\fR
+command converts between this internal representation and one that can
+be manipulated by Tcl scripts.  In most cases, the data is simply
+returned as a Tcl string.  The type indicates the intended use for the
+data, but does not actually change the representation.  For some
+types, the \fBregistry\fR command returns the data in a different form to
+make it easier to manipulate.  The following types are recognized by the
+registry command:
+.TP 17
+\fBbinary\fR
+.
+The registry value contains arbitrary binary data.  The data is represented
+exactly in Tcl, including any embedded nulls.
+.TP
+\fBnone\fR
+.
+The registry value contains arbitrary binary data with no defined
+type.  The data is represented exactly in Tcl, including any embedded
+nulls.
+.TP
+\fBsz\fR
+.
+The registry value contains a null-terminated string.  The data is 
+represented in Tcl as a string.
+.TP
+\fBexpand_sz\fR
+.
+The registry value contains a null-terminated string that contains
+unexpanded references to environment variables in the normal Windows
+style (for example,
+.QW %PATH% ).
+The data is represented in Tcl as a string.
+.TP
+\fBdword\fR
+.
+The registry value contains a little-endian 32-bit number.  The data is
+represented in Tcl as a decimal string.
+.TP
+\fBdword_big_endian\fR
+.
+The registry value contains a big-endian 32-bit number.  The data is
+represented in Tcl as a decimal string.
+.TP
+\fBlink\fR
+.
+The registry value contains a symbolic link.  The data is represented
+exactly in Tcl, including any embedded nulls.
+.TP
+\fBmulti_sz\fR
+.
+The registry value contains an array of null-terminated strings.  The
+data is represented in Tcl as a list of strings.
+.TP
+\fBresource_list\fR
+.
+The registry value contains a device-driver resource list.  The data
+is represented exactly in Tcl, including any embedded nulls.
+.PP
+In addition to the symbolically named types listed above, unknown
+types are identified using a 32-bit integer that corresponds to the
+type code returned by the system interfaces.  In this case, the data
+is represented exactly in Tcl, including any embedded nulls.
+.SH "PORTABILITY ISSUES"
+The registry command is only available on Windows.

+.SH NAME
+regsub \- Perform substitutions based on regular expression pattern matching
+.SH SYNOPSIS
+\fBregsub \fR?\fIswitches\fR? \fIexp string subSpec \fR?\fIvarName\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command matches the regular expression \fIexp\fR against
+\fIstring\fR,
+and either copies \fIstring\fR to the variable whose name is
+given by \fIvarName\fR or returns \fIstring\fR if \fIvarName\fR is not
+present.
+(Regular expression matching is described in the \fBre_syntax\fR
+reference page.)
+If there is a match, then while copying \fIstring\fR to \fIvarName\fR
+(or to the result of this command if \fIvarName\fR is not present)
+the portion of \fIstring\fR that
+matched \fIexp\fR is replaced with \fIsubSpec\fR.
+If \fIsubSpec\fR contains a
+.QW &
+or
+.QW \e0 ,
+then it is replaced in the substitution with the portion of
+\fIstring\fR that matched \fIexp\fR.
+If \fIsubSpec\fR contains a
+.QW \e\fIn\fR ,
+where \fIn\fR is a digit
+between 1 and 9, then it is replaced in the substitution with
+the portion of \fIstring\fR that matched the \fIn\fR'th
+parenthesized subexpression of \fIexp\fR.
+Additional backslashes may be used in \fIsubSpec\fR to prevent special
+interpretation of
+.QW & ,
+.QW \e0 ,
+.QW \e\fIn\fR
+and backslashes.
+The use of backslashes in \fIsubSpec\fR tends to interact badly
+with the Tcl parser's use of backslashes, so it is generally
+safest to enclose \fIsubSpec\fR in braces if it includes
+backslashes.
+.LP
+If the initial arguments to \fBregsub\fR start with \fB\-\fR then
+they are treated as switches.  The following switches are
+currently supported:
+.TP
+\fB\-all\fR
+.
+All ranges in \fIstring\fR that match \fIexp\fR are found and
+substitution is performed for each of these ranges.
+Without this switch only the first
+matching range is found and substituted.
+If \fB\-all\fR is specified, then
+.QW &
+and
+.QW \e\fIn\fR
+sequences are handled for each substitution using the information
+from the corresponding match.
+.TP
+\fB\-expanded\fR
+.
+Enables use of the expanded regular expression syntax where
+whitespace and comments are ignored.  This is the same as specifying
+the \fB(?x)\fR embedded option (see the \fBre_syntax\fR manual page).
+.TP
+\fB\-line\fR
+.
+Enables newline-sensitive matching.  By default, newline is a
+completely ordinary character with no special meaning.  With this flag,
+.QW [^
+bracket expressions and
+.QW .
+never match newline,
+.QW ^
+matches an empty string after any newline in addition to its normal
+function, and
+.QW $
+matches an empty string before any newline in
+addition to its normal function.  This flag is equivalent to
+specifying both \fB\-linestop\fR and \fB\-lineanchor\fR, or the
+\fB(?n)\fR embedded option (see the \fBre_syntax\fR manual page).
+.TP
+\fB\-linestop\fR
+.
+Changes the behavior of
+.QW [^
+bracket expressions and
+.QW .
+so that they
+stop at newlines.  This is the same as specifying the \fB(?p)\fR
+embedded option (see the \fBre_syntax\fR manual page).
+.TP
+\fB\-lineanchor\fR
+.
+Changes the behavior of
+.QW ^
+and
+.QW $
+(the
+.QW anchors )
+so they match the
+beginning and end of a line respectively.  This is the same as
+specifying the \fB(?w)\fR embedded option (see the \fBre_syntax\fR
+manual page).
+.TP
+\fB\-nocase\fR
+.
+Upper-case characters in \fIstring\fR will be converted to lower-case
+before matching against \fIexp\fR;  however, substitutions specified
+by \fIsubSpec\fR use the original unconverted form of \fIstring\fR.
+.TP
+\fB\-start\fR \fIindex\fR
+.
+Specifies a character index offset into the string to start
+matching the regular expression at.  
+The \fIindex\fR value is interpreted in the same manner
+as the \fIindex\fR argument to \fBstring index\fR.
+When using this switch,
+.QW ^
+will not match the beginning of the line, and \eA will still
+match the start of the string at \fIindex\fR.
+\fIindex\fR will be constrained to the bounds of the input string.
+.TP
+\fB\-\|\-\fR
+.
+Marks the end of switches.  The argument following this one will
+be treated as \fIexp\fR even if it starts with a \fB\-\fR.
+.PP
+If \fIvarName\fR is supplied, the command returns a count of the
+number of matching ranges that were found and replaced, otherwise the
+string after replacement is returned.
+See the manual entry for \fBregexp\fR for details on the interpretation
+of regular expressions.
+.SH EXAMPLES
+.PP
+Replace (in the string in variable \fIstring\fR) every instance of
+\fBfoo\fR which is a word by itself with \fBbar\fR:
+.PP
+.CS
+\fBregsub\fR -all {\emfoo\eM} $string bar string

+.PP
+.CS

+.PP
+Insert double-quotes around the first instance of the word
+\fBinteresting\fR, however it is capitalized.
+.PP
+.CS
+\fBregsub\fR -nocase {\eyinteresting\ey} $string {"&"} string

+.SH NAME
+return \- Return from a procedure, or set return code of a script
+.SH SYNOPSIS
+\fBreturn \fR?\fIresult\fR?
+.sp
+\fBreturn \fR?\fB\-code \fIcode\fR? ?\fIresult\fR?
+.sp
+\fBreturn \fR?\fIoption value \fR...? ?\fIresult\fR?
+.BE
+.SH DESCRIPTION
+.PP
+In its simplest usage, the \fBreturn\fR command is used without options
+in the body of a procedure to immediately return control to the caller
+of the procedure.  If a \fIresult\fR argument is provided, its value
+becomes the result of the procedure passed back to the caller.  
+If \fIresult\fR is not specified then an empty string will be returned
+to the caller as the result of the procedure.
+.PP
+The \fBreturn\fR command serves a similar function within script
+files that are evaluated by the \fBsource\fR command.  When \fBsource\fR
+evaluates the contents of a file as a script, an invocation of
+the \fBreturn\fR command will cause script evaluation
+to immediately cease, and the value \fIresult\fR (or an empty string)
+will be returned as the result of the \fBsource\fR command.
+.SH "EXCEPTIONAL RETURN CODES"
+.PP
+In addition to the result of a procedure, the return
+code of a procedure may also be set by \fBreturn\fR
+through use of the \fB\-code\fR option.
+In the usual case where the \fB\-code\fR option is not
+specified the procedure will return normally.
+However, the \fB\-code\fR option may be used to generate an
+exceptional return from the procedure.
+\fICode\fR may have any of the following values:
+.TP 13
+\fBok\fR (or \fB0\fR)
+.
+Normal return:  same as if the option is omitted.  The return code
+of the procedure is 0 (\fBTCL_OK\fR).
+.TP 13
+\fBerror\fR (or \fB1\fR)
+.
+Error return: the return code of the procedure is 1 (\fBTCL_ERROR\fR).
+The procedure command behaves in its calling context as if it
+were the command \fBerror\fR \fIresult\fR.  See below for additional
+options.
+.TP 13
+\fBreturn\fR (or \fB2\fR)
+.
+The return code of the procedure is 2 (\fBTCL_RETURN\fR).  The
+procedure command behaves in its calling context as if it
+were the command \fBreturn\fR (with no arguments).
+.TP 13
+\fBbreak\fR (or \fB3\fR)
+.
+The return code of the procedure is 3 (\fBTCL_BREAK\fR).  The
+procedure command behaves in its calling context as if it
+were the command \fBbreak\fR.
+.TP 13
+\fBcontinue\fR (or \fB4\fR)
+.
+The return code of the procedure is 4 (\fBTCL_CONTINUE\fR).  The
+procedure command behaves in its calling context as if it
+were the command \fBcontinue\fR.
+.TP 13
+\fIvalue\fR
+.
+\fIValue\fR must be an integer;  it will be returned as the
+return code for the current procedure.
+.LP
+When a procedure wants to signal that it has received invalid
+arguments from its caller, it may use \fBreturn -code error\fR
+with \fIresult\fR set to a suitable error message.  Otherwise
+usage of the \fBreturn -code\fR option is mostly limited to
+procedures that implement a new control structure.
+.PP
+The \fBreturn \-code\fR command acts similarly within script
+files that are evaluated by the \fBsource\fR command.  During the
+evaluation of the contents of a file as a script by \fBsource\fR,
+an invocation of the \fBreturn \-code \fIcode\fR command will cause
+the return code of \fBsource\fR to be \fIcode\fR.
+.SH "RETURN OPTIONS"
+.PP
+In addition to a result and a return code, evaluation of a command
+in Tcl also produces a dictionary of return options.  In general
+usage, all \fIoption value\fR pairs given as arguments to \fBreturn\fR
+become entries in the return options dictionary, and any values at all
+are acceptable except as noted below.  The \fBcatch\fR command may be
+used to capture all of this information \(em the return code, the result,
+and the return options dictionary \(em that arise from evaluation of a
+script.
+.PP
+As documented above, the \fB\-code\fR entry in the return options dictionary
+receives special treatment by Tcl.  There are other return options also
+recognized and treated specially by Tcl.  They are:
+.TP
+\fB\-errorcode \fIlist\fR
+.
+The \fB\-errorcode\fR option receives special treatment only when the value
+of the \fB\-code\fR option is \fBTCL_ERROR\fR.  Then the \fIlist\fR value
+is meant to be additional information about the error,
+presented as a Tcl list for further processing by programs.
+If no \fB\-errorcode\fR option is provided to \fBreturn\fR when
+the \fB\-code error\fR option is provided, Tcl will set the value
+of the \fB\-errorcode\fR entry in the return options dictionary 
+to the default value of \fBNONE\fR.  The \fB\-errorcode\fR return
+option will also be stored in the global variable \fBerrorCode\fR.
+.TP
+\fB\-errorinfo \fIinfo\fR
+.
+The \fB\-errorinfo\fR option receives special treatment only when the value
+of the \fB\-code\fR option is \fBTCL_ERROR\fR.  Then \fIinfo\fR is the initial
+stack trace, meant to provide to a human reader additional information
+about the context in which the error occurred.  The stack trace will
+also be stored in the global variable \fBerrorInfo\fR.  
+If no \fB\-errorinfo\fR option is provided to \fBreturn\fR when
+the \fB\-code error\fR option is provided, Tcl will provide its own
+initial stack trace value in the entry for \fB\-errorinfo\fR.  Tcl's
+initial stack trace will include only the call to the procedure, and
+stack unwinding will append information about higher stack levels, but
+there will be no information about the context of the error within
+the procedure.  Typically the \fIinfo\fR value is supplied from
+the value of \fB\-errorinfo\fR in a return options dictionary captured
+by the \fBcatch\fR command (or from the copy of that information
+stored in the global variable \fBerrorInfo\fR).
+.TP
+\fB\-errorstack \fIlist\fR
+.VS 8.6
+The \fB\-errorstack\fR option receives special treatment only when the value
+of the \fB\-code\fR option is \fBTCL_ERROR\fR.  Then \fIlist\fR is the initial
+error stack, recording actual argument values passed to each proc level.  The error stack will
+also be reachable through \fBinfo errorstack\fR.
+If no \fB\-errorstack\fR option is provided to \fBreturn\fR when
+the \fB\-code error\fR option is provided, Tcl will provide its own
+initial error stack in the entry for \fB\-errorstack\fR.  Tcl's
+initial error stack will include only the call to the procedure, and
+stack unwinding will append information about higher stack levels, but
+there will be no information about the context of the error within
+the procedure.  Typically the \fIlist\fR value is supplied from
+the value of \fB\-errorstack\fR in a return options dictionary captured
+by the \fBcatch\fR command (or from the copy of that information from
+\fBinfo errorstack\fR).
+.VE 8.6
+.TP
+\fB\-level \fIlevel\fR
+.
+The \fB\-level\fR and \fB\-code\fR options work together to set the return
+code to be returned by one of the commands currently being evaluated.
+The \fIlevel\fR value must be a non-negative integer representing a number
+of levels on the call stack.  It defines the number of levels up the stack
+at which the return code of a command currently being evaluated should
+be \fIcode\fR.  If no \fB\-level\fR option is provided, the default value
+of \fIlevel\fR is 1, so that \fBreturn\fR sets the return code that the
+current procedure returns to its caller, 1 level up the call stack.  The
+mechanism by which these options work is described in more detail below.
+.TP
+\fB\-options \fIoptions\fR
+.
+The value \fIoptions\fR must be a valid dictionary.  The entries of that
+dictionary are treated as additional \fIoption value\fR pairs for the
+\fBreturn\fR command.
+.SH "RETURN CODE HANDLING MECHANISMS"
+.PP
+Return codes are used in Tcl to control program flow.  A Tcl script
+is a sequence of Tcl commands.  So long as each command evaluation
+returns a return code of \fBTCL_OK\fR, evaluation will continue to the next
+command in the script.  Any exceptional return code (non-\fBTCL_OK\fR)
+returned by a command evaluation causes the flow on to the next
+command to be interrupted.  Script evaluation ceases, and the
+exceptional return code from the command becomes the return code
+of the full script evaluation.  This is the mechanism by which
+errors during script evaluation cause an interruption and unwinding
+of the call stack.  It is also the mechanism by which commands
+like \fBbreak\fR, \fBcontinue\fR, and \fBreturn\fR cause script
+evaluation to terminate without evaluating all commands in sequence.
+.PP
+Some of Tcl's built-in commands evaluate scripts as part of their
+functioning.  These commands can make use of exceptional return
+codes to enable special features.  For example, the built-in
+Tcl commands that provide loops \(em such as \fBwhile\fR, \fBfor\fR,
+and \fBforeach\fR \(em evaluate a script that is the body of the
+loop.  If evaluation of the loop body returns the return code
+of \fBTCL_BREAK\fR or \fBTCL_CONTINUE\fR, the loop command can react in such
+a way as to give the \fBbreak\fR and \fBcontinue\fR commands
+their documented interpretation in loops.
+.PP
+Procedure invocation also involves evaluation of a script, the body
+of the procedure.  Procedure invocation provides special treatment
+when evaluation of the procedure body returns the return code 
+\fBTCL_RETURN\fR.  In that circumstance, the \fB\-level\fR entry in the
+return options dictionary is decremented.  If after decrementing,
+the value of the \fB\-level\fR entry is 0, then the value of
+the \fB\-code\fR entry becomes the return code of the procedure.
+If after decrementing, the value of the \fB\-level\fR entry is
+greater than zero, then the return code of the procedure is
+\fBTCL_RETURN\fR.  If the procedure invocation occurred during the
+evaluation of the body of another procedure, the process will
+repeat itself up the call stack, decrementing the value of the
+\fB\-level\fR entry at each level, so that the \fIcode\fR will
+be the return code of the current command \fIlevel\fR levels
+up the call stack.  The \fBsource\fR command performs the
+same handling of the \fBTCL_RETURN\fR return code, which explains
+the similarity of \fBreturn\fR invocation during a \fBsource\fR
+to \fBreturn\fR invocation within a procedure.
+.PP
+The return code of the \fBreturn\fR command itself triggers this
+special handling by procedure invocation.  If \fBreturn\fR
+is provided the option \fB\-level 0\fR, then the return code
+of the \fBreturn\fR command itself will be the value \fIcode\fR
+of the \fB\-code\fR option (or \fBTCL_OK\fR by default).  Any other value
+for the \fB\-level\fR option (including the default value of 1)
+will cause the return code of the \fBreturn\fR command itself
+to be \fBTCL_RETURN\fR, triggering a return from the enclosing procedure.
+.SH EXAMPLES
+.PP
+First, a simple example of using \fBreturn\fR to return from a
+procedure, interrupting the procedure body.
+.PP
+.CS
+proc printOneLine {} {
+    puts "line 1"    ;# This line will be printed.
+    \fBreturn\fR		
+    puts "line 2"    ;# This line will not be printed.
+}
+.CE
+.PP
+Next, an example of using \fBreturn\fR to set the value
+returned by the procedure.
+.PP
+.CS
+proc returnX {} {\fBreturn\fR X}
+puts [returnX]    ;# prints "X"
+.CE
+.PP
+Next, a more complete example, using \fBreturn -code error\fR
+to report invalid arguments.
+.PP
+.CS
+proc factorial {n} {
+    if {![string is integer $n] || ($n < 0)} {
+        \fBreturn\fR -code error \e
+                "expected non-negative integer,\e
+                but got \e"$n\e""
+    }
+    if {$n < 2} {
+        \fBreturn\fR 1
+    }
+    set m [expr {$n - 1}]
+    set code [catch {factorial $m} factor]
+    if {$code != 0} {
+        \fBreturn\fR -code $code $factor
+    }
+    set product [expr {$n * $factor}]
+    if {$product < 0} {
+        \fBreturn\fR -code error \e
+                "overflow computing factorial of $n"
+    }
+    \fBreturn\fR $product
+}
+.CE
+.PP
+Next, a procedure replacement for \fBbreak\fR.
+.PP
+.CS
+proc myBreak {} {
+    \fBreturn\fR -code break
+}
+.CE
+.PP
+With the \fB\-level 0\fR option, \fBreturn\fR itself can serve
+as a replacement for \fBbreak\fR, with the help of \fBinterp alias\fR.
+.PP
+.CS
+interp alias {} Break {} \fBreturn\fR -level 0 -code break
+.CE
+.PP
+An example of using \fBcatch\fR and \fBreturn -options\fR to
+re-raise a caught error:
+.PP
+.CS
+proc doSomething {} {
+    set resource [allocate]
+    catch {
+        # Long script of operations

+.CE
+.PP
+Finally an example of advanced use of the \fBreturn\fR options
+to create a procedure replacement for \fBreturn\fR itself:
+.PP
+.CS
+proc myReturn {args} {
+    set result ""
+    if {[llength $args] % 2} {

+.BE
+.SH DESCRIPTION
+Safe Tcl is a mechanism for executing untrusted Tcl scripts
+safely and for providing mediated access by such scripts to
+potentially dangerous functionality.
+.PP
+Safe Tcl ensures that untrusted Tcl scripts cannot harm the
+hosting application.
+It prevents integrity and privacy attacks. Untrusted Tcl
+scripts are prevented from corrupting the state of the hosting
+application or computer. Untrusted scripts are also prevented from
+disclosing information stored on the hosting computer or in the
+hosting application to any party.
+.PP
+Safe Tcl allows a master interpreter to create safe, restricted
+interpreters that contain a set of predefined aliases for the \fBsource\fR,
+\fBload\fR, \fBfile\fR, \fBencoding\fR, and \fBexit\fR commands and
+are able to use the auto-loading and package mechanisms.
+.PP
+No knowledge of the file system structure is leaked to the
+safe interpreter, because it has access only to a virtualized path
+containing tokens. When the safe interpreter requests to source a file, it
+uses the token in the virtual path as part of the file name to source; the
+master interpreter transparently 
+translates the token into a real directory name and executes the 
+requested operation (see the section \fBSECURITY\fR below for details).
+Different levels of security can be selected by using the optional flags
+of the commands described below.
+.PP
+All commands provided in the master interpreter by Safe Tcl reside in
+the \fBsafe\fR namespace.
+.SH COMMANDS
+The following commands are provided in the master interpreter:
+.TP
+\fB::safe::interpCreate\fR ?\fIslave\fR? ?\fIoptions...\fR?
+Creates a safe interpreter, installs the aliases described in the section
+\fBALIASES\fR and initializes the auto-loading and package mechanism as
+specified by the supplied \fIoptions\fR.
+See the \fBOPTIONS\fR section below for a description of the
+optional arguments.
+If the \fIslave\fR argument is omitted, a name will be generated.
+\fB::safe::interpCreate\fR always returns the interpreter name.
+.TP
+\fB::safe::interpInit\fR \fIslave\fR ?\fIoptions...\fR?
+This command is similar to \fBinterpCreate\fR except it that does not
+create the safe interpreter. \fIslave\fR must have been created by some
+other means, like \fBinterp create\fR \fB\-safe\fR.
+.TP
+\fB::safe::interpConfigure\fR \fIslave\fR ?\fIoptions...\fR?
+If no \fIoptions\fR are given, returns the settings for all options for the
+named safe interpreter as a list of options and their current values
+for that \fIslave\fR. 
+If a single additional argument is provided,
+it will return a list of 2 elements \fIname\fR and \fIvalue\fR where
+\fIname\fR is the full name of that option and \fIvalue\fR the current value
+for that option and the \fIslave\fR.
+If more than two additional arguments are provided, it will reconfigure the
+safe interpreter and change each and only the provided options.
+See the section on \fBOPTIONS\fR below for options description.
+Example of use:
+.RS
+.PP
+.CS
+# Create new interp with the same configuration as "$i0":
+set i1 [safe::interpCreate {*}[safe::interpConfigure $i0]]
+
+# Get the current deleteHook
+set dh [safe::interpConfigure $i0  \-del]
+
+# Change (only) the statics loading ok attribute of an
+# interp and its deleteHook (leaving the rest unchanged):
+safe::interpConfigure $i0  \-delete {foo bar} \-statics 0
+.CE
+.RE
+.TP
+\fB::safe::interpDelete\fR \fIslave\fR
+Deletes the safe interpreter and cleans up the corresponding  
+master interpreter data structures.
+If a \fIdeleteHook\fR script was specified for this interpreter it is
+evaluated before the interpreter is deleted, with the name of the
+interpreter as an additional argument.
+.TP
+\fB::safe::interpFindInAccessPath\fR \fIslave\fR \fIdirectory\fR
+This command finds and returns the token for the real directory
+\fIdirectory\fR in the safe interpreter's current virtual access path.
+It generates an error if the directory is not found.
+Example of use:
+.RS
+.PP
+.CS
+$slave eval [list set tk_library \e
+      [::safe::interpFindInAccessPath $name $tk_library]]
+.CE
+.RE
+.TP
+\fB::safe::interpAddToAccessPath\fR \fIslave\fR \fIdirectory\fR
+This command adds \fIdirectory\fR to the virtual path maintained for the
+safe interpreter in the master, and returns the token that can be used in
+the safe interpreter to obtain access to files in that directory.
+If the directory is already in the virtual path, it only returns the token
+without adding the directory to the virtual path again.
+Example of use:
+.RS
+.PP
+.CS
+$slave eval [list set tk_library \e
+      [::safe::interpAddToAccessPath $name $tk_library]]
+.CE
+.RE
+.TP
+\fB::safe::setLogCmd\fR ?\fIcmd arg...\fR?
+This command installs a script that will be called when interesting
+life cycle events occur for a safe interpreter.
+When called with no arguments, it returns the currently installed script.
+When called with one argument, an empty string, the currently installed
+script is removed and logging is turned off.
+The script will be invoked with one additional argument, a string
+describing the event of interest.
+The main purpose is to help in debugging safe interpreters.
+Using this facility you can get complete error messages while the safe
+interpreter gets only generic error messages.
+This prevents a safe interpreter from seeing messages about failures
+and other events that might contain sensitive information such as real
+directory names.
+.RS
+.PP
+Example of use:
+.PP
+.CS
+::safe::setLogCmd puts stderr
+.CE
+.PP
+Below is the output of a sample session in which a safe interpreter
+attempted to source a file not found in its virtual access path.
+Note that the safe interpreter only received an error message saying that
+the file was not found:
+.PP
+.CS
+NOTICE for slave interp10 : Created
+NOTICE for slave interp10 : Setting accessPath=(/foo/bar) staticsok=1 nestedok=0 deletehook=()
+NOTICE for slave interp10 : auto_path in interp10 has been set to {$p(:0:)}
+ERROR for slave interp10 : /foo/bar/init.tcl: no such file or directory
+.CE
+.RE
+.SS OPTIONS
+The following options are common to 
+\fB::safe::interpCreate\fR, \fB::safe::interpInit\fR, 
+and \fB::safe::interpConfigure\fR.
+Any option name can be abbreviated to its minimal 
+non-ambiguous name.
+Option names are not case sensitive.
+.TP 
+\fB\-accessPath\fR \fIdirectoryList\fR
+This option sets the list of directories from which the safe interpreter
+can \fBsource\fR and \fBload\fR files.
+If this option is not specified, or if it is given as the
+empty list, the safe interpreter will use the same directories as its
+master for auto-loading.
+See the section \fBSECURITY\fR below for more detail about virtual paths, 
+tokens and access control.
+.TP
+\fB\-statics\fR \fIboolean\fR
+This option specifies if the safe interpreter will be allowed
+to load statically linked packages (like \fBload {} Tk\fR).
+The default value is \fBtrue\fR : 
+safe interpreters are allowed to load statically linked packages.
+.TP
+\fB\-noStatics\fR
+This option is a convenience shortcut for \fB\-statics false\fR and
+thus specifies that the safe interpreter will not be allowed
+to load statically linked packages.
+.TP
+\fB\-nested\fR \fIboolean\fR
+This option specifies if the safe interpreter will be allowed
+to load packages into its own sub-interpreters.
+The default value is \fBfalse\fR : 
+safe interpreters are not allowed to load packages into
+their own sub-interpreters.
+.TP
+\fB\-nestedLoadOk\fR
+This option is a convenience shortcut for \fB\-nested true\fR and
+thus specifies the safe interpreter will be allowed
+to load packages into its own sub-interpreters.
+.TP 
+\fB\-deleteHook\fR \fIscript\fR
+When this option is given a non-empty \fIscript\fR, it will be
+evaluated in the master with the name of
+the safe interpreter as an additional argument
+just before actually deleting the safe interpreter.
+Giving an empty value removes any currently installed deletion hook
+script for that safe interpreter.
+The default value (\fB{}\fR) is not to have any deletion call back.
+.SH ALIASES
+The following aliases are provided in a safe interpreter:
+.TP
+\fBsource\fR \fIfileName\fR
+The requested file, a Tcl source file, is sourced into the safe interpreter
+if it is found.
+The \fBsource\fR alias can only source files from directories in
+the virtual path for the safe interpreter. The \fBsource\fR alias requires
+the safe interpreter to
+use one of the token names in its virtual path to denote the directory in
+which the file to be sourced can be found.
+See the section on \fBSECURITY\fR for more discussion of restrictions on
+valid filenames.
+.TP
+\fBload\fR \fIfileName\fR
+The requested file, a shared object file, is dynamically loaded into the
+safe interpreter if it is found.
+The filename must contain a token name mentioned in the virtual path for
+the safe interpreter for it to be found successfully.
+Additionally, the shared object file must contain a safe entry point; see
+the manual page for the \fBload\fR command for more details.
+.TP
+\fBfile\fR ?\fIsubCmd args...\fR?
+The \fBfile\fR alias provides access to a safe subset of the subcommands of
+the \fBfile\fR command; it allows only \fBdirname\fR, \fBjoin\fR,
+\fBextension\fR, \fBroot\fR, \fBtail\fR, \fBpathname\fR and \fBsplit\fR
+subcommands. For more details on what these subcommands do see the manual
+page for the \fBfile\fR command.
+.TP
+\fBencoding\fR ?\fIsubCmd args...\fR?
+The \fBencoding\fR alias provides access to a safe subset of the
+subcommands of the \fBencoding\fR command;  it disallows setting of
+the system encoding, but allows all other subcommands including
+\fBsystem\fR to check the current encoding.
+.TP
+\fBexit\fR
+The calling interpreter is deleted and its computation is stopped, but the
+Tcl process in which this interpreter exists is not terminated.
+.SH SECURITY
+Safe Tcl does not attempt to completely prevent annoyance and
+denial of service attacks. These forms of attack prevent the
+application or user from temporarily using the computer to perform
+useful work, for example by consuming all available CPU time or
+all available screen real estate.
+These attacks, while aggravating, are deemed to be of lesser importance
+in general than integrity and privacy attacks that Safe Tcl
+is to prevent.
+.PP
+The commands available in a safe interpreter, in addition to
+the safe set as defined in \fBinterp\fR manual page, are mediated aliases
+for \fBsource\fR, \fBload\fR, \fBexit\fR, and safe subsets of
+\fBfile\fR and \fBencoding\fR. The safe interpreter can also auto-load
+code and it can request that packages be loaded.
+.PP
+Because some of these commands access the local file system, there is a
+potential for information leakage about its directory structure.
+To prevent this, commands that take file names as arguments in a safe
+interpreter use tokens instead of the real directory names.
+These tokens are translated to the real directory name while a request to,
+e.g., source a file is mediated by the master interpreter.
+This virtual path system is maintained in the master interpreter for each safe
+interpreter created by \fB::safe::interpCreate\fR or initialized by
+\fB::safe::interpInit\fR and
+the path maps tokens accessible in the safe interpreter into real path
+names on the local file system thus preventing safe interpreters 
+from gaining knowledge about the
+structure of the file system of the host on which the interpreter is
+executing.
+The only valid file names arguments
+for the \fBsource\fR and \fBload\fR aliases provided to the slave
+are path in the form of 
+\fB[file join \fItoken filename\fB]\fR (i.e. when using the
+native file path formats: \fItoken\fB/\fIfilename\fR
+on Unix and \fItoken\fB\e\fIfilename\fR on Windows),
+where \fItoken\fR is representing one of the directories 
+of the \fIaccessPath\fR list and \fIfilename\fR is
+one file in that directory (no sub directories access are allowed).
+.PP
+When a token is used in a safe interpreter in a request to source or
+load a file, the token is checked and
+translated to a real path name and the file to be
+sourced or loaded is located on the file system.
+The safe interpreter never gains knowledge of the actual path name under
+which the file is stored on the file system.
+.PP
+To further prevent potential information leakage from sensitive files that
+are accidentally included in the set of files that can be sourced by a safe
+interpreter, the \fBsource\fR alias restricts access to files
+meeting the following constraints: the file name must
+fourteen characters or shorter, must not contain more than one dot
+.PQ \fB.\fR "" ,
+must end up with the extension
+.PQ \fB.tcl\fR
+or be called
+.PQ \fBtclIndex\fR .
+.PP
+Each element of the initial access path
+list will be assigned a token that will be set in
+the slave \fBauto_path\fR and the first element of that list will be set as
+the \fBtcl_library\fR for that slave.
+.PP
+If the access path argument is not given or is the empty list, 
+the default behavior is to let the slave access the same packages
+as the master has access to (Or to be more precise: 
+only packages written in Tcl (which by definition cannot be dangerous
+as they run in the slave interpreter) and C extensions that
+provides a _SafeInit entry point). For that purpose, the master's 
+\fBauto_path\fR will be used to construct the slave access path. 
+In order that the slave successfully loads the Tcl library files
+(which includes the auto-loading mechanism itself) the \fBtcl_library\fR will be
+added or moved to the first position if necessary, in the 
+slave access path, so the slave
+\fBtcl_library\fR will be the same as the master's (its real
+path will still be invisible to the slave though). 
+In order that auto-loading works the same for the slave and
+the master in this by default case, the first-level
+sub directories of each directory in the master \fBauto_path\fR will
+also be added (if not already included) to the slave access path.
+You can always specify a more
+restrictive path for which sub directories will never be searched by 
+explicitly specifying your directory list with the \fB\-accessPath\fR flag
+instead of relying on this default mechanism.
+.PP
+When the \fIaccessPath\fR is changed after the first creation or
+initialization (i.e. through \fBinterpConfigure -accessPath \fR\fIlist\fR),
+an \fBauto_reset\fR is automatically evaluated in the safe interpreter
+to synchronize its \fBauto_index\fR with the new token list.

+.SH NAME
+scan \- Parse string using conversion specifiers in the style of sscanf
+.SH SYNOPSIS
+\fBscan \fIstring format \fR?\fIvarName varName ...\fR?
+.BE
+.SH INTRODUCTION
+.PP
+This command parses substrings from an input string in a fashion similar
+to the ANSI C \fBsscanf\fR procedure and returns a count of the number of
+conversions performed, or -1 if the end of the input string is reached
+before any conversions have been performed.  \fIString\fR gives the input
+to be parsed and \fIformat\fR indicates how to parse it, using \fB%\fR
+conversion specifiers as in \fBsscanf\fR.  Each \fIvarName\fR gives the
+name of a variable; when a substring is scanned from \fIstring\fR that
+matches a conversion specifier, the substring is assigned to the
+corresponding variable.
+If no \fIvarName\fR variables are specified, then \fBscan\fR works in an
+inline manner, returning the data that would otherwise be stored in the
+variables as a list.  In the inline case, an empty string is returned when
+the end of the input string is reached before any conversions have been
+performed.
+.SH "DETAILS ON SCANNING"
+.PP
+\fBScan\fR operates by scanning \fIstring\fR and \fIformat\fR together.
+If the next character in \fIformat\fR is a blank or tab then it
+matches any number of white space characters in \fIstring\fR (including
+zero).
+Otherwise, if it is not a \fB%\fR character then it 
+must match the next character of \fIstring\fR.
+When a \fB%\fR is encountered in \fIformat\fR, it indicates
+the start of a conversion specifier.
+A conversion specifier contains up to four fields after the \fB%\fR:
+a XPG3 position specifier (or a \fB*\fR to indicate the converted
+value is to be discarded instead of assigned to any variable); a number
+indicating a maximum substring width; a size modifier; and a
+conversion character.
+All of these fields are optional except for the conversion character.
+The fields that are present must appear in the order given above.
+.PP
+When \fBscan\fR finds a conversion specifier in \fIformat\fR, it
+first skips any white-space characters in \fIstring\fR (unless the
+conversion character is \fB[\fR or \fBc\fR).
+Then it converts the next input characters according to the 
+conversion specifier and stores the result in the variable given
+by the next argument to \fBscan\fR.
+.SS "OPTIONAL POSITIONAL SPECIFIER"
+.PP
+If the \fB%\fR is followed by a decimal number and a \fB$\fR, as in
+.QW \fB%2$d\fR ,
+then the variable to use is not taken from the next
+sequential argument.  Instead, it is taken from the argument indicated
+by the number, where 1 corresponds to the first \fIvarName\fR.  If
+there are any positional specifiers in \fIformat\fR then all of the
+specifiers must be positional.  Every \fIvarName\fR on the argument
+list must correspond to exactly one conversion specifier or an error
+is generated, or in the inline case, any position can be specified
+at most once and the empty positions will be filled in with empty strings.
+.SS "OPTIONAL SIZE MODIFIER"
+.PP
+The size modifier field is used only when scanning a substring into
+one of Tcl's integer values.  The size modifier field dictates the
+integer range acceptable to be stored in a variable, or, for the inline
+case, in a position in the result list.
+The syntactically valid values for the size modifier are \fBh\fR, \fBL\fR,
+\fBl\fR, and \fBll\fR.  The \fBh\fR size modifier value is equivalent
+to the absence of a size modifier in the the conversion specifier.
+Either one indicates the integer range to be stored is limited to
+the same range produced by the \fBint()\fR function of the \fBexpr\fR
+command.  The \fBL\fR size modifier is equivalent to the \fBl\fR size
+modifier. Either one indicates the integer range to be stored is
+limited to the same range produced by the \fBwide()\fR function of
+the \fBexpr\fR command.  The \fBll\fR size modifier indicates that
+the integer range to be stored is unlimited.
+.SS "MANDATORY CONVERSION CHARACTER"
+.PP
+The following conversion characters are supported:
+.TP
+\fBd\fR
+.
+The input substring must be a decimal integer.
+It is read in and the integer value is stored in the variable,
+truncated as required by the size modifier value.
+.TP
+\fBo\fR
+.
+The input substring must be an octal integer. It is read in and the 
+integer value is stored in the variable,
+truncated as required by the size modifier value.
+.TP
+\fBx\fR
+.
+The input substring must be a hexadecimal integer.
+It is read in and the integer value is stored in the variable,
+truncated as required by the size modifier value.
+.TP
+\fBb\fR
+.
+The input substring must be a binary integer.
+It is read in and the integer value is stored in the variable,
+truncated as required by the size modifier value.
+.TP
+\fBu\fR
+.
+The input substring must be a decimal integer.
+The integer value is truncated as required by the size modifier
+value, and the corresponding unsigned value for that truncated
+range is computed and stored in the variable as a decimal string.
+The conversion makes no sense without reference to a truncation range,
+so the size modifier \fBll\fR is not permitted in combination
+with conversion character \fBu\fR.
+.TP
+\fBi\fR
+.
+The input substring must be an integer.  The base (i.e. decimal, binary,
+octal, or hexadecimal) is determined in the same fashion as described in
+\fBexpr\fR.  The integer value is stored in the variable,
+truncated as required by the size modifier value.
+.TP
+\fBc\fR
+.
+A single character is read in and its Unicode value is stored in 
+the variable as an integer value.
+Initial white space is not skipped in this case, so the input
+substring may be a white-space character.
+.TP
+\fBs\fR
+.
+The input substring consists of all the characters up to the next 
+white-space character; the characters are copied to the variable.
+.TP
+\fBe\fR or \fBf\fR or \fBg\fR
+.
+The input substring must be a floating-point number consisting 
+of an optional sign, a string of decimal digits possibly
+containing a decimal point, and an optional exponent consisting 
+of an \fBe\fR or \fBE\fR followed by an optional sign and a string of 
+decimal digits.
+It is read in and stored in the variable as a floating-point value.
+.TP
+\fB[\fIchars\fB]\fR
+.
+The input substring consists of one or more characters in \fIchars\fR.
+The matching string is stored in the variable.
+If the first character between the brackets is a \fB]\fR then
+it is treated as part of \fIchars\fR rather than the closing
+bracket for the set.
+If \fIchars\fR
+contains a sequence of the form \fIa\fB\-\fIb\fR then any
+character between \fIa\fR and \fIb\fR (inclusive) will match.
+If the first or last character between the brackets is a \fB\-\fR, then
+it is treated as part of \fIchars\fR rather than indicating a range.
+.TP
+\fB[^\fIchars\fB]\fR
+.
+The input substring consists of one or more characters not in \fIchars\fR.
+The matching string is stored in the variable.
+If the character immediately following the \fB^\fR is a \fB]\fR then it is 
+treated as part of the set rather than the closing bracket for 
+the set.
+If \fIchars\fR
+contains a sequence of the form \fIa\fB\-\fIb\fR then any
+character between \fIa\fR and \fIb\fR (inclusive) will be excluded
+from the set.
+If the first or last character between the brackets is a \fB\-\fR, then
+it is treated as part of \fIchars\fR rather than indicating a range value.
+.TP
+\fBn\fR
+.
+No input is consumed from the input string.  Instead, the total number
+of characters scanned from the input string so far is stored in the variable.
+.PP
+The number of characters read from the input for a conversion is the
+largest number that makes sense for that particular conversion (e.g.
+as many decimal digits as possible for \fB%d\fR, as 
+many octal digits as possible for \fB%o\fR, and so on).
+The input substring for a given conversion terminates either when a
+white-space character is encountered or when the maximum substring 
+width has been reached, whichever comes first.
+If a \fB*\fR is present in the conversion specifier 
+then no variable is assigned and the next scan argument is not consumed.
+.SH "DIFFERENCES FROM ANSI SSCANF"
+.PP
+The behavior of the \fBscan\fR command is the same as the behavior of
+the ANSI C \fBsscanf\fR procedure except for the following differences:
+.IP [1]
+\fB%p\fR conversion specifier is not supported.
+.IP [2]
+For \fB%c\fR conversions a single character value is
+converted to a decimal string, which is then assigned to the
+corresponding \fIvarName\fR;
+no substring width may be specified for this conversion.
+.IP [3]
+The \fBh\fR modifier is always ignored and the \fBl\fR and \fBL\fR
+modifiers are ignored when converting real values (i.e. type
+\fBdouble\fR is used for the internal representation).  The \fBll\fR
+modifier has no \fBsscanf\fR counterpart.
+.IP [4]
+If the end of the input string is reached before any conversions have been
+performed and no variables are given, an empty string is returned.

+.SH NAME
+seek \- Change the access position for an open channel
+.SH SYNOPSIS
+\fBseek \fIchannelId offset \fR?\fIorigin\fR?
+.BE
+.SH DESCRIPTION
+.PP
+Changes the current access position for \fIchannelId\fR.
+.PP
+\fIChannelId\fR must be an identifier for an open channel such as a
+Tcl standard channel (\fBstdin\fR, \fBstdout\fR, or \fBstderr\fR),
+the return value from an invocation of \fBopen\fR or \fBsocket\fR, or
+the result of a channel creation command provided by a Tcl extension.
+.PP
+The \fIoffset\fR and \fIorigin\fR
+arguments specify the position at which the next read or write will occur
+for \fIchannelId\fR. \fIOffset\fR must be an integer (which may be
+negative) and \fIorigin\fR must be one of the following:
+.TP 10
+\fBstart\fR
+.
+The new access position will be \fIoffset\fR bytes from the start
+of the underlying file or device.
+.TP 10
+\fBcurrent\fR
+.
+The new access position will be \fIoffset\fR bytes from the current
+access position; a negative \fIoffset\fR moves the access position
+backwards in the underlying file or device.
+.TP 10
+\fBend\fR
+.
+The new access position will be \fIoffset\fR bytes from the end of
+the file or device.  A negative \fIoffset\fR places the access position
+before the end of file, and a positive \fIoffset\fR places the access
+position after the end of file.
+.PP
+The \fIorigin\fR argument defaults to \fBstart\fR.
+.PP
+The command flushes all buffered output for the channel before the command
+returns, even if the channel is in non-blocking mode.
+It also discards any buffered and unread input.
+This command returns an empty string.
+An error occurs if this command is applied to channels whose underlying
+file or device does not support seeking.
+.PP
+Note that \fIoffset\fR values are byte offsets, not character
+offsets.  Both \fBseek\fR and \fBtell\fR operate in terms of bytes,
+not characters, unlike \fBread\fR.
+.SH EXAMPLES
+.PP
+Read a file twice:
+.PP
+.CS
+set f [open file.txt]
+set data1 [read $f]
+\fBseek\fR $f 0
+set data2 [read $f]

+.SH NAME
+self \- method call internal introspection
+.SH SYNOPSIS
+.nf
+package require TclOO
+
+\fBself\fR ?\fIsubcommand\fR?
+.fi
+.BE
+.SH DESCRIPTION
+The \fBself\fR command, which should only be used from within the context of a
+call to a method (i.e. inside a method, constructor or destructor body) is
+used to allow the method to discover information about how it was called. It
+takes an argument, \fIsubcommand\fR, that tells it what sort of information is
+actually desired; if omitted the result will be the same as if \fBself
+object\fR was invoked. The supported subcommands are:
+.TP
+\fBself call\fR
+.
+This returns a two-element list describing the method implementations used to
+implement the current call chain. The first element is the same as would be
+reported by \fBinfo object\fR \fBcall\fR for the current method (except that this
+also reports useful values from within constructors and destructors, whose
+names are reported as \fB<constructor>\fR and \fB<destructor>\fR
+respectively), and the second element is an index into the first element's
+list that indicates which actual implementation is currently executing (the
+first implementation to execute is always at index 0).
+.TP
+\fBself caller\fR
+.
+When the method was invoked from inside another object method, this subcommand
+returns a three element list describing the containing object and method. The
+first element describes the declaring object or class of the method, the
+second element is the name of the object on which the containing method was
+invoked, and the third element is the name of the method (with the strings
+\fB<constructor>\fR and \fB<destructor>\fR indicating constructors and
+destructors respectively).
+.TP
+\fBself class\fR
+.
+This returns the name of the class that the current method was defined within.
+Note that this will change as the chain of method implementations is traversed
+with \fBnext\fR, and that if the method was defined on an object then this
+will fail.
+.RS
+.PP
+If you want the class of the current object, you need to use this other
+construct:
+.PP
+.CS
+info object class [\fBself object\fR]
+.CE
+.RE
+.TP
+\fBself filter\fR
+.
+When invoked inside a filter, this subcommand returns a three element list
+describing the filter. The first element gives the name of the object or class
+that declared the filter (note that this may be different from the object or
+class that provided the implementation of the filter), the second element is
+either \fBobject\fR or \fBclass\fR depending on whether the declaring entity
+was an object or class, and the third element is the name of the filter.
+.TP
+\fBself method\fR
+.
+This returns the name of the current method (with the strings
+\fB<constructor>\fR and \fB<destructor>\fR indicating constructors and
+destructors respectively).
+.TP
+\fBself namespace\fR
+.
+This returns the name of the unique namespace of the object that the method
+was invoked upon.
+.TP
+\fBself next\fR
+.
+When invoked from a method that is not at the end of a call chain (i.e. where
+the \fBnext\fR command will invoke an actual method implementation), this
+subcommand returns a two element list describing the next element in the
+method call chain; the first element is the name of the class or object that
+declares the next part of the call chain, and the second element is the name
+of the method (with the strings \fB<constructor>\fR and \fB<destructor>\fR
+indicating constructors and destructors respectively). If invoked from a
+method that is at the end of a call chain, this subcommand returns the empty
+string.
+.TP
+\fBself object\fR
+.
+This returns the name of the object that the method was invoked upon.
+.TP
+\fBself target\fR
+.
+When invoked inside a filter implementation, this subcommand returns a two
+element list describing the method being filtered. The first element will be
+the name of the declarer of the method, and the second element will be the
+actual name of the method.
+.SH EXAMPLES
+.PP
+This example shows basic use of \fBself\fR to provide information about the
+current object:
+.PP
+.CS
+oo::class create c {
+    method foo {} {
+        puts "this is the [\fBself\fR] object"
+    }
+}
+c create a
+c create b
+a foo                \fI\(-> prints "this is the ::a object"\fR
+b foo                \fI\(-> prints "this is the ::b object"\fR
+.CE
+.PP
+This demonstrates what a method call chain looks like, and how traversing
+along it changes the index into it:
+.PP
+.CS
+oo::class create c {
+    method x {} {
+        puts "Cls: [\fBself call\fR]"
+    }
+}
+c create a
+oo::objdefine a {
+    method x {} {
+        puts "Obj: [\fBself call\fR]"
+        next
+        puts "Obj: [\fBself call\fR]"
+    }
+}
+a x     \fI\(-> Obj: {{method x object method} {method x ::c method}} 0\fR
+        \fI\(-> Cls: {{method x object method} {method x ::c method}} 1\fR

+.sp
+\fBsocket \fR?\fIoptions\fR? \fIhost port\fR
+.sp
+\fBsocket\fR \fB\-server \fIcommand\fR ?\fIoptions\fR? \fIport\fR
+.BE
+.SH DESCRIPTION
+.PP
+This command opens a network socket and returns a channel identifier
+that may be used in future invocations of commands like \fBread\fR,
+\fBputs\fR and \fBflush\fR.  At present only the TCP network protocol
+is supported over IPv4 and IPv6; future releases may include support
+for additional protocols.  The \fBsocket\fR command may be used to
+open either the client or server side of a connection, depending on
+whether the \fB\-server\fR switch is specified.
+.PP
+Note that the default encoding for \fIall\fR sockets is the system
+encoding, as returned by \fBencoding system\fR.  Most of the time, you
+will need to use \fBchan configure\fR to alter this to something else,
+such as \fIutf\-8\fR (ideal for communicating with other Tcl
+processes) or \fIiso8859\-1\fR (useful for many network protocols,
+especially the older ones).
+.SH "CLIENT SOCKETS"
+.PP
+If the \fB\-server\fR option is not specified, then the client side of a
+connection is opened and the command returns a channel identifier
+that can be used for both reading and writing.
+\fIPort\fR and \fIhost\fR specify a port
+to connect to;  there must be a server accepting connections on
+this port.  \fIPort\fR is an integer port number
+(or service name, where supported and understood by the host operating
+system) and \fIhost\fR
+is either a domain-style name such as \fBwww.tcl.tk\fR or
+a numerical IPv4 or IPv6 address such as \fB127.0.0.1\fR or \fB2001:DB8::1\fR.
+Use \fIlocalhost\fR to refer to the host on which the command is invoked.
+.PP
+The following options may also be present before \fIhost\fR
+to specify additional information about the connection:
+.TP
+\fB\-myaddr\fI addr\fR
+.
+\fIAddr\fR gives the domain-style name or numerical IP address of
+the client-side network interface to use for the connection.
+This option may be useful if the client machine has multiple network
+interfaces.  If the option is omitted then the client-side interface
+will be chosen by the system software.
+.TP
+\fB\-myport\fI port\fR
+.
+\fIPort\fR specifies an integer port number (or service name, where
+supported and understood by the host operating system) to use for the
+client's
+side of the connection.  If this option is omitted, the client's
+port number will be chosen at random by the system software.
+.TP
+\fB\-async\fR
+.
+This option will cause the client socket to be connected
+asynchronously. This means that the socket will be created immediately
+but may not yet be connected to the server, when the call to
+\fBsocket\fR returns.
+.RS
+.PP
+When a \fBgets\fR or \fBflush\fR is done on the socket before the
+connection attempt succeeds or fails, if the socket is in blocking
+mode, the operation will wait until the connection is completed or
+fails. If the socket is in nonblocking mode and a \fBgets\fR or
+\fBflush\fR is done on the socket before the connection attempt
+succeeds or fails, the operation returns immediately and
+\fBfblocked\fR on the socket returns 1. Synchronous client sockets may
+be switched (after they have connected) to operating in asynchronous
+mode using:
+.PP
+.CS
+\fBchan configure \fIchan \fB\-blocking 0\fR
+.CE
+.PP
+See the \fBchan configure\fR command for more details.
+.PP
+The Tcl event loop should be running while an asynchronous connection
+is in progress, because it may have to do several connection attempts
+in the background. Running the event loop also allows you to set up a
+writable channel event on the socket to get notified when the
+asynchronous connection has succeeded or failed. See the \fBvwait\fR
+and the \fBchan\fR commands for more details on the event loop and
+channel events.
+.RE
+.SH "SERVER SOCKETS"
+.PP
+If the \fB\-server\fR option is specified then the new socket will be
+a server that listens on the given \fIport\fR (either an integer or a
+service name, where supported and understood by the host operating
+system; if \fIport\fR is zero, the operating system will allocate a
+free port to the server socket which may be discovered by using
+\fBchan configure\fR to read the \fB\-sockname\fR option). If the host
+supports both, IPv4 and IPv6, the socket will listen on both address
+families. Tcl will automatically accept connections to the given port.
+For each connection Tcl will create a new channel that may be used to
+communicate with the client.  Tcl then invokes \fIcommand\fR (properly
+a command prefix list, see the \fBEXAMPLES\fR below) with three
+additional arguments: the name of the new channel, the address, in
+network address notation, of the client's host, and the client's port
+number.
+.PP
+The following additional option may also be specified before \fIport\fR:
+.TP
+\fB\-myaddr\fI addr\fR
+.
+\fIAddr\fR gives the domain-style name or numerical IP address of the
+server-side network interface to use for the connection.  This option
+may be useful if the server machine has multiple network interfaces.
+If the option is omitted then the server socket is bound to the
+wildcard address so that it can accept connections from any
+interface. If \fIaddr\fR is a domain name that resolves to multiple IP
+addresses that are available on the local machine, the socket will
+listen on all of them.
+.PP
+Server channels cannot be used for input or output; their sole use is to
+accept new client connections. The channels created for each incoming
+client connection are opened for input and output. Closing the server
+channel shuts down the server so that no new connections will be
+accepted;  however, existing connections will be unaffected.
+.PP
+Server sockets depend on the Tcl event mechanism to find out when
+new connections are opened.  If the application does not enter the
+event loop, for example by invoking the \fBvwait\fR command or
+calling the C procedure \fBTcl_DoOneEvent\fR, then no connections
+will be accepted.
+.PP
+If \fIport\fR is specified as zero, the operating system will allocate
+an unused port for use as a server socket.  The port number actually
+allocated may be retrieved from the created server socket using the
+\fBchan configure\fR command to retrieve the \fB\-sockname\fR option as
+described below.
+.SH "CONFIGURATION OPTIONS"
+.PP
+The \fBchan configure\fR command can be used to query several readonly
+configuration options for socket channels:
+.TP
+\fB\-error\fR
+.
+This option gets the current error status of the given socket.  This

+.SH SYNOPSIS
+\fBsource \fIfileName\fR
+.sp
+\fBsource\fR \fB\-encoding \fIencodingName fileName\fR
+.BE
+.SH DESCRIPTION
+.PP
+This command takes the contents of the specified file or resource
+and passes it to the Tcl interpreter as a text script.  The return
+value from \fBsource\fR is the return value of the last command
+executed in the script.  If an error occurs in evaluating the contents
+of the script then the \fBsource\fR command will return that error.
+If a \fBreturn\fR command is invoked from within the script then the
+remainder of the file will be skipped and the \fBsource\fR command
+will return normally with the result from the \fBreturn\fR command.
+.PP
+The end-of-file character for files is
+.QW \e32
+(^Z) for all platforms.
+The source command will read files up to this character.  This
+restriction does not exist for the \fBread\fR or \fBgets\fR commands,
+allowing for files containing code and data segments (scripted documents).
+If you require a
+.QW ^Z
+in code for string comparison, you can use
+.QW \e032
+or
+.QW \eu001a ,
+which will be safely substituted by the Tcl interpreter into
+.QW ^Z .
+.PP
+The \fB\-encoding\fR option is used to specify the encoding of
+the data stored in \fIfileName\fR.  When the \fB\-encoding\fR option
+is omitted, the system encoding is assumed.
+.SH EXAMPLE

+\fBsplit \fIstring \fR?\fIsplitChars\fR?
+.BE
+.SH DESCRIPTION
+.PP
+Returns a list created by splitting \fIstring\fR at each character
+that is in the \fIsplitChars\fR argument.
+Each element of the result list will consist of the
+characters from \fIstring\fR that lie between instances of the
+characters in \fIsplitChars\fR.
+Empty list elements will be generated if \fIstring\fR contains
+adjacent characters in \fIsplitChars\fR, or if the first or last
+character of \fIstring\fR is in \fIsplitChars\fR.
+If \fIsplitChars\fR is an empty string then each character of
+\fIstring\fR becomes a separate element of the result list.
+\fISplitChars\fR defaults to the standard white-space characters.

+.SH SYNOPSIS
+\fBstring \fIoption arg \fR?\fIarg ...?\fR
+.BE
+.SH DESCRIPTION
+.PP
+Performs one of several string operations, depending on \fIoption\fR.
+The legal \fIoption\fRs (which may be abbreviated) are:
+.TP
+\fBstring compare\fR ?\fB\-nocase\fR? ?\fB\-length int\fR? \fIstring1 string2\fR
+.
+Perform a character-by-character comparison of strings \fIstring1\fR
+and \fIstring2\fR.  Returns \-1, 0, or 1, depending on whether
+\fIstring1\fR is lexicographically less than, equal to, or greater
+than \fIstring2\fR.  If \fB\-length\fR is specified, then only the
+first \fIlength\fR characters are used in the comparison.  If
+\fB\-length\fR is negative, it is ignored.  If \fB\-nocase\fR is
+specified, then the strings are compared in a case-insensitive manner.
+.TP
+\fBstring equal\fR ?\fB\-nocase\fR? ?\fB\-length int\fR? \fIstring1 string2\fR
+.
+Perform a character-by-character comparison of strings \fIstring1\fR
+and \fIstring2\fR.  Returns 1 if \fIstring1\fR and \fIstring2\fR are
+identical, or 0 when not.  If \fB\-length\fR is specified, then only
+the first \fIlength\fR characters are used in the comparison.  If
+\fB\-length\fR is negative, it is ignored.  If \fB\-nocase\fR is
+specified, then the strings are compared in a case-insensitive manner.
+.TP
+\fBstring first \fIneedleString haystackString\fR ?\fIstartIndex\fR?
+.
+Search \fIhaystackString\fR for a sequence of characters that exactly match
+the characters in \fIneedleString\fR.  If found, return the index of the
+first character in the first such match within \fIhaystackString\fR.  If not
+found, return \-1.  If \fIstartIndex\fR is specified (in any of the
+forms described in \fBSTRING INDICES\fR), then the search is
+constrained to start with the character in \fIhaystackString\fR specified by
+the index.  For example,
+.RS
+.PP
+.CS
+\fBstring first a 0a23456789abcdef 5\fR
+.CE
+.PP
+will return \fB10\fR, but
+.PP
+.CS
+\fBstring first a 0123456789abcdef 11\fR
+.CE
+.PP
+will return \fB\-1\fR.
+.RE
+.TP
+\fBstring index \fIstring charIndex\fR
+.
+Returns the \fIcharIndex\fR'th character of the \fIstring\fR argument.
+A \fIcharIndex\fR of 0 corresponds to the first character of the
+string.  \fIcharIndex\fR may be specified as described in the
+\fBSTRING INDICES\fR section.
+.RS
+.PP
+If \fIcharIndex\fR is less than 0 or greater than or equal to the
+length of the string then this command returns an empty string.
+.RE
+.TP
+\fBstring is \fIclass\fR ?\fB\-strict\fR? ?\fB\-failindex \fIvarname\fR? \fIstring\fR
+.
+Returns 1 if \fIstring\fR is a valid member of the specified character
+class, otherwise returns 0.  If \fB\-strict\fR is specified, then an
+empty string returns 0, otherwise an empty string will return 1 on
+any class.  If \fB\-failindex\fR is specified, then if the function
+returns 0, the index in the string where the class was no longer valid
+will be stored in the variable named \fIvarname\fR.  The \fIvarname\fR
+will not be set if \fBstring is\fR returns 1.  The following character
+classes are recognized (the class name can be abbreviated):
+.RS
+.IP \fBalnum\fR 12
+Any Unicode alphabet or digit character.
+.IP \fBalpha\fR 12
+Any Unicode alphabet character.
+.IP \fBascii\fR 12
+Any character with a value less than \eu0080 (those that are in the
+7\-bit ascii range).
+.IP \fBboolean\fR 12
+Any of the forms allowed to \fBTcl_GetBoolean\fR.
+.IP \fBcontrol\fR 12
+Any Unicode control character.
+.IP \fBdigit\fR 12
+Any Unicode digit character.  Note that this includes characters
+outside of the [0\-9] range.
+.IP \fBdouble\fR 12
+Any of the valid forms for a double in Tcl, with optional surrounding
+whitespace.  In case of under/overflow in the value, 0 is returned and
+the \fIvarname\fR will contain \-1.
+.IP \fBentier\fR 12
+.VS 8.6
+Any of the valid string formats for an integer value of arbitrary size
+in Tcl, with optional surrounding whitespace. The formats accepted are
+exactly those accepted by the C routine \fBTcl_GetBignumFromObj\fR.
+.VE
+.IP \fBfalse\fR 12
+Any of the forms allowed to \fBTcl_GetBoolean\fR where the value is
+false.
+.IP \fBgraph\fR 12
+Any Unicode printing character, except space.
+.IP \fBinteger\fR 12
+Any of the valid string formats for a 32-bit integer value in Tcl,
+with optional surrounding whitespace.  In case of under/overflow in
+the value, 0 is returned and the \fIvarname\fR will contain \-1.
+.IP \fBlist\fR 12
+Any proper list structure, with optional surrounding whitespace. In
+case of improper list structure, 0 is returned and the \fIvarname\fR
+will contain the index of the
+.QW element
+where the list parsing fails, or \-1 if this cannot be determined.
+.IP \fBlower\fR 12
+Any Unicode lower case alphabet character.
+.IP \fBprint\fR 12
+Any Unicode printing character, including space.
+.IP \fBpunct\fR 12
+Any Unicode punctuation character.
+.IP \fBspace\fR 12
+Any Unicode whitespace character, zero width space (U+200b),
+word joiner (U+2060) and zero width no-break space (U+feff) (=BOM).
+.IP \fBtrue\fR 12
+Any of the forms allowed to \fBTcl_GetBoolean\fR where the value is
+true.
+.IP \fBupper\fR 12
+Any upper case alphabet character in the Unicode character set.
+.IP \fBwideinteger\fR 12
+Any of the valid forms for a wide integer in Tcl, with optional
+surrounding whitespace.  In case of under/overflow in the value, 0 is
+returned and the \fIvarname\fR will contain \-1.
+.IP \fBwordchar\fR 12
+Any Unicode word character.  That is any alphanumeric character, and
+any Unicode connector punctuation characters (e.g. underscore).
+.IP \fBxdigit\fR 12
+Any hexadecimal digit character ([0\-9A\-Fa\-f]).
+.PP
+In the case of \fBboolean\fR, \fBtrue\fR and \fBfalse\fR, if the
+function will return 0, then the \fIvarname\fR will always be set to
+0, due to the varied nature of a valid boolean value.
+.RE
+.TP
+\fBstring last \fIneedleString haystackString\fR ?\fIlastIndex\fR?
+.
+Search \fIhaystackString\fR for a sequence of characters that exactly match
+the characters in \fIneedleString\fR.  If found, return the index of the
+first character in the last such match within \fIhaystackString\fR.  If there
+is no match, then return \-1.  If \fIlastIndex\fR is specified (in any
+of the forms described in \fBSTRING INDICES\fR), then only the
+characters in \fIhaystackString\fR at or before the specified \fIlastIndex\fR
+will be considered by the search.  For example,
+.RS
+.PP
+.CS
+\fBstring last a 0a23456789abcdef 15\fR
+.CE
+.PP
+will return \fB10\fR, but
+.PP
+.CS
+\fBstring last a 0a23456789abcdef 9\fR
+.CE
+.PP
+will return \fB1\fR.
+.RE
+.TP
+\fBstring length \fIstring\fR
+.
+Returns a decimal string giving the number of characters in
+\fIstring\fR.  Note that this is not necessarily the same as the
+number of bytes used to store the string.  If the value is a
+byte array value (such as those returned from reading a binary encoded
+channel), then this will return the actual byte length of the value.
+.TP
+\fBstring map\fR ?\fB\-nocase\fR? \fImapping string\fR
+.
+Replaces substrings in \fIstring\fR based on the key-value pairs in
+\fImapping\fR.  \fImapping\fR is a list of \fIkey value key value ...\fR
+as in the form returned by \fBarray get\fR.  Each instance of a
+key in the string will be replaced with its corresponding value.  If
+\fB\-nocase\fR is specified, then matching is done without regard to
+case differences. Both \fIkey\fR and \fIvalue\fR may be multiple
+characters.  Replacement is done in an ordered manner, so the key
+appearing first in the list will be checked first, and so on.
+\fIstring\fR is only iterated over once, so earlier key replacements
+will have no affect for later key matches.  For example,
+.RS
+.PP
+.CS
+\fBstring map {abc 1 ab 2 a 3 1 0} 1abcaababcabababc\fR
+.CE
+.PP
+will return the string \fB01321221\fR.
+.PP
+Note that if an earlier \fIkey\fR is a prefix of a later one, it will
+completely mask the later one.  So if the previous example is
+reordered like this,
+.PP
+.CS
+\fBstring map {1 0 ab 2 a 3 abc 1} 1abcaababcabababc\fR
+.CE
+.PP
+it will return the string \fB02c322c222c\fR.
+.RE
+.TP
+\fBstring match\fR ?\fB\-nocase\fR? \fIpattern\fR \fIstring\fR
+.
+See if \fIpattern\fR matches \fIstring\fR; return 1 if it does, 0 if
+it does not.  If \fB\-nocase\fR is specified, then the pattern attempts
+to match against the string in a case insensitive manner.  For the two
+strings to match, their contents must be identical except that the
+following special sequences may appear in \fIpattern\fR:
+.RS
+.IP \fB*\fR 10
+Matches any sequence of characters in \fIstring\fR, including a null
+string.
+.IP \fB?\fR 10
+Matches any single character in \fIstring\fR.
+.IP \fB[\fIchars\fB]\fR 10
+Matches any character in the set given by \fIchars\fR.  If a sequence
+of the form \fIx\fB\-\fIy\fR appears in \fIchars\fR, then any
+character between \fIx\fR and \fIy\fR, inclusive, will match.  When
+used with \fB\-nocase\fR, the end points of the range are converted to
+lower case first.  Whereas {[A\-z]} matches
+.QW _
+when matching case-sensitively (since
+.QW _
+falls between the
+.QW Z
+and
+.QW a ),
+with \fB\-nocase\fR this is considered like {[A\-Za\-z]} (and
+probably what was meant in the first place).
+.IP \fB\e\fIx\fR 10
+Matches the single character \fIx\fR.  This provides a way of avoiding
+the special interpretation of the characters \fB*?[]\e\fR in
+\fIpattern\fR.
+.RE
+.TP
+\fBstring range \fIstring first last\fR
+.
+Returns a range of consecutive characters from \fIstring\fR, starting
+with the character whose index is \fIfirst\fR and ending with the
+character whose index is \fIlast\fR. An index of 0 refers to the first
+character of the string.  \fIfirst\fR and \fIlast\fR may be specified
+as for the \fBindex\fR method.  If \fIfirst\fR is less than zero then
+it is treated as if it were zero, and if \fIlast\fR is greater than or
+equal to the length of the string then it is treated as if it were
+\fBend\fR.  If \fIfirst\fR is greater than \fIlast\fR then an empty
+string is returned.
+.TP
+\fBstring repeat \fIstring count\fR
+.
+Returns \fIstring\fR repeated \fIcount\fR number of times.
+.TP
+\fBstring replace \fIstring first last\fR ?\fInewstring\fR?
+.
+Removes a range of consecutive characters from \fIstring\fR, starting
+with the character whose index is \fIfirst\fR and ending with the
+character whose index is \fIlast\fR.  An index of 0 refers to the
+first character of the string.  \fIFirst\fR and \fIlast\fR may be
+specified as for the \fBindex\fR method.  If \fInewstring\fR is
+specified, then it is placed in the removed character range.  If
+\fIfirst\fR is less than zero then it is treated as if it were zero,
+and if \fIlast\fR is greater than or equal to the length of the string
+then it is treated as if it were \fBend\fR.  If \fIfirst\fR is greater
+than \fIlast\fR or the length of the initial string, or \fIlast\fR is
+less than 0, then the initial string is returned untouched.
+.TP
+\fBstring reverse \fIstring\fR
+.
+Returns a string that is the same length as \fIstring\fR but with its
+characters in the reverse order.
+.TP
+\fBstring tolower \fIstring\fR ?\fIfirst\fR? ?\fIlast\fR?
+.
+Returns a value equal to \fIstring\fR except that all upper (or title)
+case letters have been converted to lower case.  If \fIfirst\fR is
+specified, it refers to the first char index in the string to start
+modifying.  If \fIlast\fR is specified, it refers to the char index in
+the string to stop at (inclusive).  \fIfirst\fR and \fIlast\fR may be
+specified using the forms described in \fBSTRING INDICES\fR.
+.TP
+\fBstring totitle \fIstring\fR ?\fIfirst\fR? ?\fIlast\fR?
+.
+Returns a value equal to \fIstring\fR except that the first character
+in \fIstring\fR is converted to its Unicode title case variant (or
+upper case if there is no title case variant) and the rest of the
+string is converted to lower case.  If \fIfirst\fR is specified, it
+refers to the first char index in the string to start modifying.  If
+\fIlast\fR is specified, it refers to the char index in the string to
+stop at (inclusive).  \fIfirst\fR and \fIlast\fR may be specified
+using the forms described in \fBSTRING INDICES\fR.
+.TP
+\fBstring toupper \fIstring\fR ?\fIfirst\fR? ?\fIlast\fR?
+.
+Returns a value equal to \fIstring\fR except that all lower (or title)
+case letters have been converted to upper case.  If \fIfirst\fR is
+specified, it refers to the first char index in the string to start
+modifying.  If \fIlast\fR is specified, it refers to the char index in
+the string to stop at (inclusive).  \fIfirst\fR and \fIlast\fR may be
+specified using the forms described in \fBSTRING INDICES\fR.
+.TP
+\fBstring trim \fIstring\fR ?\fIchars\fR?
+.
+Returns a value equal to \fIstring\fR except that any leading or
+trailing characters present in the string given by \fIchars\fR are removed.  If
+\fIchars\fR is not specified then white space is removed (any character
+for which \fBstring is space\fR returns 1, and "\0").

+The last char of the string minus the specified integer offset \fIN\fR (e.g.,
+.QW \fBend\-1\fR
+would refer to the
+.QW c

+.SH NAME
+subst \- Perform backslash, command, and variable substitutions
+.SH SYNOPSIS
+\fBsubst \fR?\fB\-nobackslashes\fR? ?\fB\-nocommands\fR? ?\fB\-novariables\fR? \fIstring\fR
+.BE
+.SH DESCRIPTION
+.PP
+This command performs variable substitutions, command substitutions,
+and backslash substitutions on its \fIstring\fR argument and
+returns the fully-substituted result.
+The substitutions are performed in exactly the same way as for
+Tcl commands.
+As a result, the \fIstring\fR argument is actually substituted twice,
+once by the Tcl parser in the usual fashion for Tcl commands, and
+again by the \fIsubst\fR command.
+.PP
+If any of the \fB\-nobackslashes\fR, \fB\-nocommands\fR, or
+\fB\-novariables\fR are specified, then the corresponding substitutions
+are not performed.
+For example, if \fB\-nocommands\fR is specified, command substitution
+is not performed:  open and close brackets are treated as ordinary characters
+with no special interpretation.
+.PP
+Note that the substitution of one kind can include substitution of 
+other kinds.  For example, even when the \fB\-novariables\fR option
+is specified, command substitution is performed without restriction.
+This means that any variable substitution necessary to complete the
+command substitution will still take place.  Likewise, any command
+substitution necessary to complete a variable substitution will
+take place, even when \fB\-nocommands\fR is specified.  See the
+\fBEXAMPLES\fR below.
+.PP
+If an error occurs during substitution, then \fBsubst\fR will return
+that error.  If a break exception occurs during command or variable
+substitution, the result of the whole substitution will be the
+string (as substituted) up to the start of the substitution that
+raised the exception.  If a continue exception occurs during the
+evaluation of a command or variable substitution, an empty string
+will be substituted for that entire command or variable substitution
+(as long as it is well-formed Tcl.)  If a return exception occurs,
+or any other return code is returned during command or variable
+substitution, then the returned value is substituted for that
+substitution.  See the \fBEXAMPLES\fR below.  In this way, all exceptional
+return codes are
+.QW caught
+by \fBsubst\fR.  The \fBsubst\fR command
+itself will either return an error, or will complete successfully.
+.SH EXAMPLES
+.PP
+When it performs its substitutions, \fIsubst\fR does not give any
+special treatment to double quotes or curly braces (except within
+command substitutions) so the script
+.PP
+.CS
+set a 44
+\fBsubst\fR {xyz {$a}}
+.CE
+.PP
+returns
+.QW "\fBxyz {44}\fR" ,
+not
+.QW "\fBxyz {$a}\fR"
+and the script
+.PP
+.CS
+set a "p\e} q \e{r"
+\fBsubst\fR {xyz {$a}}
+.CE
+.PP
+returns
+.QW "\fBxyz {p} q {r}\fR" ,
+not
+.QW "\fBxyz {p\e} q \e{r}\fR".
+.PP
+When command substitution is performed, it includes any variable
+substitution necessary to evaluate the script.
+.PP
+.CS
+set a 44
+\fBsubst\fR -novariables {$a [format $a]}
+.CE
+.PP
+returns
+.QW "\fB$a 44\fR" ,
+not
+.QW "\fB$a $a\fR" .
+Similarly, when
+variable substitution is performed, it includes any command
+substitution necessary to retrieve the value of the variable.
+.PP
+.CS
+proc b {} {return c}
+array set a {c c [b] tricky}
+\fBsubst\fR -nocommands {[b] $a([b])}
+.CE
+.PP
+returns
+.QW "\fB[b] c\fR" ,
+not
+.QW "\fB[b] tricky\fR" .
+.PP
+The continue and break exceptions allow command substitutions to
+prevent substitution of the rest of the command substitution and the
+rest of \fIstring\fR respectively, giving script authors more options
+when processing text using \fIsubst\fR.  For example, the script
+.PP
+.CS
+\fBsubst\fR {abc,[break],def}
+.CE
+.PP
+returns
+.QW \fBabc,\fR ,
+not
+.QW \fBabc,,def\fR
+and the script
+.PP
+.CS
+\fBsubst\fR {abc,[continue;expr {1+2}],def}
+.CE
+.PP
+returns
+.QW \fBabc,,def\fR ,
+not
+.QW \fBabc,3,def\fR .
+.PP
+Other exceptional return codes substitute the returned value
+.PP
+.CS
+\fBsubst\fR {abc,[return foo;expr {1+2}],def}
+.CE
+.PP
+returns
+.QW \fBabc,foo,def\fR ,
+not
+.QW \fBabc,3,def\fR
+and
+.PP
+.CS
+\fBsubst\fR {abc,[return -code 10 foo;expr {1+2}],def}
+.CE
+.PP
+also returns
+.QW \fBabc,foo,def\fR ,
+not
+.QW \fBabc,3,def\fR .

+.SH NAME
+switch \- Evaluate one of several scripts, depending on a given value
+.SH SYNOPSIS
+\fBswitch \fR?\fIoptions\fR?\fI string pattern body \fR?\fIpattern body \fR...?
+.sp
+\fBswitch \fR?\fIoptions\fR?\fI string \fR{\fIpattern body \fR?\fIpattern body \fR...?}
+.BE
+.SH DESCRIPTION
+.PP
+The \fBswitch\fR command matches its \fIstring\fR argument against each of
+the \fIpattern\fR arguments in order.
+As soon as it finds a \fIpattern\fR that matches \fIstring\fR it
+evaluates the following \fIbody\fR argument by passing it recursively
+to the Tcl interpreter and returns the result of that evaluation.
+If the last \fIpattern\fR argument is \fBdefault\fR then it matches
+anything.
+If no \fIpattern\fR argument
+matches \fIstring\fR and no default is given, then the \fBswitch\fR
+command returns an empty string.
+.PP
+If the initial arguments to \fBswitch\fR start with \fB\-\fR then
+they are treated as options
+unless there are exactly two arguments to \fBswitch\fR (in which case the
+first must the \fIstring\fR and the second must be the
+\fIpattern\fR/\fIbody\fR list).
+The following options are currently supported:
+.TP 10
+\fB\-exact\fR
+.
+Use exact matching when comparing \fIstring\fR to a pattern.  This
+is the default.
+.TP 10
+\fB\-glob\fR
+.
+When matching \fIstring\fR to the patterns, use glob-style matching
+(i.e. the same as implemented by the \fBstring match\fR command).
+.TP 10
+\fB\-regexp\fR
+.
+When matching \fIstring\fR to the patterns, use regular
+expression matching
+(as described in the \fBre_syntax\fR reference page).
+.TP 10
+\fB\-nocase\fR
+.
+Causes comparisons to be handled in a case-insensitive manner.
+.TP 10
+\fB\-matchvar\fR \fIvarName\fR
+.
+This option (only legal when \fB\-regexp\fR is also specified)
+specifies the name of a variable into which the list of matches
+found by the regular expression engine will be written.  The first
+element of the list written will be the overall substring of the input
+string (i.e. the \fIstring\fR argument to \fBswitch\fR) matched, the
+second element of the list will be the substring matched by the first
+capturing parenthesis in the regular expression that matched, and so
+on.  When a \fBdefault\fR branch is taken, the variable will have the
+empty list written to it.  This option may be specified at the same
+time as the \fB\-indexvar\fR option.
+.TP 10
+\fB\-indexvar\fR \fIvarName\fR
+.
+This option (only legal when \fB\-regexp\fR is also specified)
+specifies the name of a variable into which the list of indices
+referring to matching substrings
+found by the regular expression engine will be written.  The first
+element of the list written will be a two-element list specifying the
+index of the start and index of the first character after the end of
+the overall substring of the input
+string (i.e. the \fIstring\fR argument to \fBswitch\fR) matched, in a
+similar way to the \fB\-indices\fR option to the \fBregexp\fR can
+obtain.  Similarly, the second element of the list refers to the first
+capturing parenthesis in the regular expression that matched, and so
+on.  When a \fBdefault\fR branch is taken, the variable will have the
+empty list written to it.  This option may be specified at the same
+time as the \fB\-matchvar\fR option.
+.TP 10
+\fB\-\|\-\fR
+.
+Marks the end of options.  The argument following this one will
+be treated as \fIstring\fR even if it starts with a \fB\-\fR.
+This is not required when the matching patterns and bodies are grouped
+together in a single argument.
+.PP
+Two syntaxes are provided for the \fIpattern\fR and \fIbody\fR arguments.
+The first uses a separate argument for each of the patterns and commands;
+this form is convenient if substitutions are desired on some of the
+patterns or commands.
+The second form places all of the patterns and commands together into
+a single argument; the argument must have proper list structure, with
+the elements of the list being the patterns and commands.
+The second form makes it easy to construct multi-line switch commands,
+since the braces around the whole list make it unnecessary to include a
+backslash at the end of each line.
+Since the \fIpattern\fR arguments are in braces in the second form,
+no command or variable substitutions are performed on them;  this makes
+the behavior of the second form different than the first form in some
+cases.
+.PP
+If a \fIbody\fR is specified as
+.QW \fB\-\fR
+it means that the \fIbody\fR
+for the next pattern should also be used as the body for this
+pattern (if the next pattern also has a body of
+.QW \fB\-\fR
+then the body after that is used, and so on).
+This feature makes it possible to share a single \fIbody\fR among
+several patterns.
+.PP
+Beware of how you place comments in \fBswitch\fR commands.  Comments
+should only be placed \fBinside\fR the execution body of one of the
+patterns, and not intermingled with the patterns.
+.SH "EXAMPLES"
+.PP
+The \fBswitch\fR command can match against variables and not just
+literals, as shown here (the result is \fI2\fR):
+.PP
+.CS
+set foo "abc"
+\fBswitch\fR abc a \- b {expr {1}} $foo {expr {2}} default {expr {3}}
+.CE
+.PP
+Using glob matching and the fall-through body is an alternative to
+writing regular expressions with alternations, as can be seen here
+(this returns \fI1\fR):
+.PP
+.CS
+\fBswitch\fR \-glob aaab {
+    a*b     \-
+    b       {expr {1}}
+    a*      {expr {2}}
+    default {expr {3}}
+}
+.CE
+.PP
+Whenever nothing matches, the \fBdefault\fR clause (which must be
+last) is taken.  This example has a result of \fI3\fR:
+.PP
+.CS
+\fBswitch\fR xyz {
+    a \-
+    b {
+        # Correct Comment Placement
+        expr {1}
+    }
+    c {
+        expr {2}
+    }
+    default {
+        expr {3}
+    }
+}
+.CE
+.PP
+When matching against regular expressions, information about what
+exactly matched is easily obtained using the \fB\-matchvar\fR option:
+.PP
+.CS
+\fBswitch\fR \-regexp \-matchvar foo \-\- $bar {
+    a(b*)c {
+        puts "Found [string length [lindex $foo 1]] 'b's"
+    }
+    d(e*)f(g*)h {
+        puts "Found [string length [lindex $foo 1]] 'e's and\e
+                [string length [lindex $foo 2]] 'g's"

+.SH NAME
+tclsh \- Simple shell containing Tcl interpreter
+.SH SYNOPSIS
+\fBtclsh\fR ?\fB\-encoding \fIname\fR? ?\fIfileName arg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+\fBTclsh\fR is a shell-like application that reads Tcl commands
+from its standard input or from a file and evaluates them.
+If invoked with no arguments then it runs interactively, reading
+Tcl commands from standard input and printing command results and
+error messages to standard output.
+It runs until the \fBexit\fR command is invoked or until it
+reaches end-of-file on its standard input.
+If there exists a file \fB.tclshrc\fR (or \fBtclshrc.tcl\fR on
+the Windows platforms) in the home directory of
+the user, interactive \fBtclsh\fR evaluates the file as a Tcl script
+just before reading the first command from standard input.
+.SH "SCRIPT FILES"
+.PP
+If \fBtclsh\fR is invoked with arguments then the first few arguments
+specify the name of a script file, and, optionally, the encoding of
+the text data stored in that script file. Any additional arguments
+are made available to the script as variables (see below).
+Instead of reading commands from standard input \fBtclsh\fR will
+read Tcl commands from the named file;  \fBtclsh\fR will exit
+when it reaches the end of the file.
+The end of the file may be marked either by the physical end of
+the medium, or by the character,
+.QW \e032
+.PQ \eu001a ", control-Z" .
+If this character is present in the file, the \fBtclsh\fR application
+will read text up to but not including the character.  An application
+that requires this character in the file may safely encode it as
+.QW \e032 ,
+.QW \ex1a ,
+or
+.QW \eu001a ;
+or may generate it by use of commands such as \fBformat\fR or \fBbinary\fR.
+There is no automatic evaluation of \fB.tclshrc\fR when the name
+of a script file is presented on the \fBtclsh\fR command
+line, but the script file can always \fBsource\fR it if desired.
+.PP
+If you create a Tcl script in a file whose first line is
+.PP
+.CS
+\fB#!/usr/local/bin/tclsh\fR
+.CE
+.PP
+then you can invoke the script file directly from your shell if
+you mark the file as executable.
+This assumes that \fBtclsh\fR has been installed in the default
+location in /usr/local/bin;  if it is installed somewhere else
+then you will have to modify the above line to match.
+Many UNIX systems do not allow the \fB#!\fR line to exceed about
+30 characters in length, so be sure that the \fBtclsh\fR
+executable can be accessed with a short file name.
+.PP
+An even better approach is to start your script files with the
+following three lines:
+.PP
+.CS
+\fB#!/bin/sh
+# the next line restarts using tclsh \e
+exec tclsh "$0" ${1+"$@"}\fR
+.CE
+.PP
+This approach has three advantages over the approach in the previous
+paragraph.  First, the location of the \fBtclsh\fR binary does not have
+to be hard-wired into the script:  it can be anywhere in your shell
+search path.  Second, it gets around the 30-character file name limit
+in the previous approach.
+Third, this approach will work even if \fBtclsh\fR is
+itself a shell script (this is done on some systems in order to
+handle multiple architectures or operating systems:  the \fBtclsh\fR
+script selects one of several binaries to run).  The three lines
+cause both \fBsh\fR and \fBtclsh\fR to process the script, but the
+\fBexec\fR is only executed by \fBsh\fR.
+\fBsh\fR processes the script first;  it treats the second
+line as a comment and executes the third line.
+The \fBexec\fR statement cause the shell to stop processing and
+instead to start up \fBtclsh\fR to reprocess the entire script.
+When \fBtclsh\fR starts up, it treats all three lines as comments,
+since the backslash at the end of the second line causes the third
+line to be treated as part of the comment on the second line.
+.PP
+You should note that it is also common practice to install tclsh with
+its version number as part of the name.  This has the advantage of
+allowing multiple versions of Tcl to exist on the same system at once,
+but also the disadvantage of making it harder to write scripts that
+start up uniformly across different versions of Tcl.
+.SH "VARIABLES"
+.PP
+\fBTclsh\fR sets the following Tcl variables:
+.TP 15
+\fBargc\fR
+.
+Contains a count of the number of \fIarg\fR arguments (0 if none),
+not including the name of the script file.
+.TP 15
+\fBargv\fR
+.
+Contains a Tcl list whose elements are the \fIarg\fR arguments,
+in order, or an empty string if there are no \fIarg\fR arguments.
+.TP 15
+\fBargv0\fR
+.
+Contains \fIfileName\fR if it was specified.
+Otherwise, contains the name by which \fBtclsh\fR was invoked.
+.TP 15
+\fBtcl_interactive\fR
+.
+Contains 1 if \fBtclsh\fR is running interactively (no
+\fIfileName\fR was specified and standard input is a terminal-like
+device), 0 otherwise.
+.SH PROMPTS
+.PP
+When \fBtclsh\fR is invoked interactively it normally prompts for each
+command with
+.QW "\fB% \fR" .
+You can change the prompt by setting the
+variables \fBtcl_prompt1\fR and \fBtcl_prompt2\fR.  If variable
+\fBtcl_prompt1\fR exists then it must consist of a Tcl script
+to output a prompt;  instead of outputting a prompt \fBtclsh\fR
+will evaluate the script in \fBtcl_prompt1\fR.
+The variable \fBtcl_prompt2\fR is used in a similar way when
+a newline is typed but the current command is not yet complete;
+if \fBtcl_prompt2\fR is not set then no prompt is output for
+incomplete commands.

+.SH DESCRIPTION
+.PP
+The \fBtcltest\fR package provides several utility commands useful
+in the construction of test suites for code instrumented to be
+run by evaluation of Tcl commands.  Notably the built-in commands
+of the Tcl library itself are tested by a test suite using the
+tcltest package.
+.PP
+All the commands provided by the \fBtcltest\fR package are defined
+in and exported from the \fB::tcltest\fR namespace, as indicated in
+the \fBSYNOPSIS\fR above.  In the following sections, all commands
+will be described by their simple names, in the interest of brevity.
+.PP
+The central command of \fBtcltest\fR is \fBtest\fR that defines
+and runs a test.  Testing with \fBtest\fR involves evaluation
+of a Tcl script and comparing the result to an expected result, as
+configured and controlled by a number of options.  Several other
+commands provided by \fBtcltest\fR govern the configuration of
+\fBtest\fR and the collection of many \fBtest\fR commands into
+test suites.
+.PP
+See \fBCREATING TEST SUITES WITH TCLTEST\fR below for an extended example
+of how to use the commands of \fBtcltest\fR to produce test suites
+for your Tcl-enabled code.
+.SH COMMANDS
+.TP
+\fBtest\fR \fIname description\fR ?\fI\-option value ...\fR?
+.
+Defines and possibly runs a test with the name \fIname\fR and
+description \fIdescription\fR.  The name and description of a test
+are used in messages reported by \fBtest\fR during the
+test, as configured by the options of \fBtcltest\fR.  The
+remaining \fIoption value\fR arguments to \fBtest\fR
+define the test, including the scripts to run, the conditions
+under which to run them, the expected result, and the means
+by which the expected and actual results should be compared.
+See \fBTESTS\fR below for a complete description of the valid
+options and how they define a test.  The \fBtest\fR command
+returns an empty string.
+.TP
+\fBtest\fR \fIname description\fR ?\fIconstraints\fR? \fIbody result\fR
+.
+This form of \fBtest\fR is provided to support test suites written
+for version 1 of the \fBtcltest\fR package, and also a simpler
+interface for a common usage.  It is the same as
+.QW "\fBtest\fR \fIname description\fB \-constraints \fIconstraints\fB \-body \fIbody\fB \-result \fIresult\fR" .
+All other options to \fBtest\fR
+take their default values.  When \fIconstraints\fR is omitted, this
+form of \fBtest\fR can be distinguished from the first because
+all \fIoption\fRs begin with
+.QW \- .
+.TP
+\fBloadTestedCommands\fR
+.
+Evaluates in the caller's context the script specified by 
+\fBconfigure \-load\fR or \fBconfigure \-loadfile\fR.
+Returns the result of that script evaluation, including any error
+raised by the script.  Use this command and the related
+configuration options to provide the commands to be tested to
+the interpreter running the test suite.
+.TP
+\fBmakeFile\fR \fIcontents name\fR ?\fIdirectory\fR?
+.
+Creates a file named \fIname\fR relative to
+directory \fIdirectory\fR and write \fIcontents\fR
+to that file using the encoding \fBencoding system\fR.
+If \fIcontents\fR does not end with a newline, a newline
+will be appended so that the file named \fIname\fR
+does end with a newline.  Because the system encoding is used,
+this command is only suitable for making text files.
+The file will be removed by the next evaluation
+of \fBcleanupTests\fR, unless it is removed by
+\fBremoveFile\fR first.  The default value of
+\fIdirectory\fR is the directory \fBconfigure \-tmpdir\fR.
+Returns the full path of the file created.  Use this command
+to create any text file required by a test with contents as needed.
+.TP
+\fBremoveFile\fR \fIname\fR ?\fIdirectory\fR?
+.
+Forces the file referenced by \fIname\fR to be removed.  This file name
+should be relative to \fIdirectory\fR.   The default value of
+\fIdirectory\fR is the directory \fBconfigure \-tmpdir\fR.
+Returns an empty string.  Use this command to delete files
+created by \fBmakeFile\fR.
+.TP
+\fBmakeDirectory\fR \fIname\fR ?\fIdirectory\fR?
+.
+Creates a directory named \fIname\fR relative to directory \fIdirectory\fR.
+The directory will be removed by the next evaluation of \fBcleanupTests\fR,
+unless it is removed by \fBremoveDirectory\fR first.
+The default value of \fIdirectory\fR is the directory
+\fBconfigure \-tmpdir\fR.
+Returns the full path of the directory created.  Use this command
+to create any directories that are required to exist by a test.
+.TP
+\fBremoveDirectory\fR \fIname\fR ?\fIdirectory\fR?
+.
+Forces the directory referenced by \fIname\fR to be removed. This
+directory should be relative to \fIdirectory\fR.
+The default value of \fIdirectory\fR is the directory
+\fBconfigure \-tmpdir\fR.
+Returns an empty string.  Use this command to delete any directories
+created by \fBmakeDirectory\fR.
+.TP
+\fBviewFile\fR \fIfile\fR ?\fIdirectory\fR?
+.
+Returns the contents of \fIfile\fR, except for any
+final newline, just as \fBread \-nonewline\fR would return.
+This file name should be relative to \fIdirectory\fR.
+The default value of \fIdirectory\fR is the directory
+\fBconfigure \-tmpdir\fR.  Use this command
+as a convenient way to turn the contents of a file generated
+by a test into the result of that test for matching against
+an expected result.  The contents of the file are read using
+the system encoding, so its usefulness is limited to text
+files.
+.TP
+\fBcleanupTests\fR
+.
+Intended to clean up and summarize after several tests have been
+run.  Typically called once per test file, at the end of the file
+after all tests have been completed.  For best effectiveness, be
+sure that the \fBcleanupTests\fR is evaluated even if an error
+occurs earlier in the test file evaluation.
+.RS
+.PP
+Prints statistics about the tests run and removes files that were
+created by \fBmakeDirectory\fR and \fBmakeFile\fR since the
+last \fBcleanupTests\fR.  Names of files and directories
+in the directory \fBconfigure \-tmpdir\fR created since
+the last \fBcleanupTests\fR, but not created by
+\fBmakeFile\fR or \fBmakeDirectory\fR are printed
+to \fBoutputChannel\fR.  This command also restores the original
+shell environment, as described by the global \fBenv\fR
+array. Returns an empty string.
+.RE
+.TP
+\fBrunAllTests\fR
+.
+This is a master command meant to run an entire suite of tests,
+spanning multiple files and/or directories, as governed by
+the configurable options of \fBtcltest\fR.  See \fBRUNNING ALL TESTS\fR
+below for a complete description of the many variations possible
+with \fBrunAllTests\fR.
+.SS "CONFIGURATION COMMANDS"
+.TP
+\fBconfigure\fR
+.
+Returns the list of configurable options supported by \fBtcltest\fR.
+See \fBCONFIGURABLE OPTIONS\fR below for the full list of options,
+their valid values, and their effect on \fBtcltest\fR operations.
+.TP
+\fBconfigure \fIoption\fR
+.
+Returns the current value of the supported configurable option \fIoption\fR.
+Raises an error if \fIoption\fR is not a supported configurable option.
+.TP
+\fBconfigure \fIoption value\fR ?\fI\-option value ...\fR?
+.
+Sets the value of each configurable option \fIoption\fR to the
+corresponding value \fIvalue\fR, in order.  Raises an error if
+an \fIoption\fR is not a supported configurable option, or if
+\fIvalue\fR is not a valid value for the corresponding \fIoption\fR,
+or if a \fIvalue\fR is not provided.  When an error is raised, the
+operation of \fBconfigure\fR is halted, and subsequent \fIoption value\fR
+arguments are not processed.
+.RS
+.PP
+If the environment variable \fB::env(TCLTEST_OPTIONS)\fR exists when
+the \fBtcltest\fR package is loaded (by \fBpackage require\fR \fBtcltest\fR)
+then its value is taken as a list of arguments to pass to \fBconfigure\fR.
+This allows the default values of the configuration options to be
+set by the environment.
+.RE
+.TP
+\fBcustomMatch \fImode script\fR
+.
+Registers \fImode\fR as a new legal value of the \fB\-match\fR option
+to \fBtest\fR.  When the \fB\-match \fImode\fR option is
+passed to \fBtest\fR, the script \fIscript\fR will be evaluated
+to compare the actual result of evaluating the body of the test
+to the expected result.
+To perform the match, the \fIscript\fR is completed with two additional
+words, the expected result, and the actual result, and the completed script
+is evaluated in the global namespace.
+The completed script is expected to return a boolean value indicating
+whether or not the results match.  The built-in matching modes of
+\fBtest\fR are \fBexact\fR, \fBglob\fR, and \fBregexp\fR.
+.TP
+\fBtestConstraint \fIconstraint\fR ?\fIboolean\fR?
+.
+Sets or returns the boolean value associated with the named \fIconstraint\fR.
+See \fBTEST CONSTRAINTS\fR below for more information.
+.TP
+\fBinterpreter\fR ?\fIexecutableName\fR?
+.
+Sets or returns the name of the executable to be \fBexec\fRed by
+\fBrunAllTests\fR to run each test file when
+\fBconfigure \-singleproc\fR is false.
+The default value for \fBinterpreter\fR is the name of the
+currently running program as returned by \fBinfo nameofexecutable\fR.
+.TP
+\fBoutputChannel\fR ?\fIchannelID\fR?
+.
+Sets or returns the output channel ID.  This defaults to \fBstdout\fR.
+Any test that prints test related output should send
+that output to \fBoutputChannel\fR rather than letting
+that output default to \fBstdout\fR.
+.TP
+\fBerrorChannel\fR ?\fIchannelID\fR?
+.
+Sets or returns the error channel ID.  This defaults to \fBstderr\fR.
+Any test that prints error messages should send
+that output to \fBerrorChannel\fR rather than printing
+directly to \fBstderr\fR.

+.SS "OTHER COMMANDS"
+.PP
+The remaining commands provided by \fBtcltest\fR have better
+alternatives provided by \fBtcltest\fR or \fBTcl\fR itself.  They
+are retained to support existing test suites, but should be avoided
+in new code.
+.TP
+\fBtest\fR \fIname description optionList\fR
+.
+This form of \fBtest\fR was provided to enable passing many
+options spanning several lines to \fBtest\fR as a single
+argument quoted by braces, rather than needing to backslash quote
+the newlines between arguments to \fBtest\fR.  The \fIoptionList\fR
+argument is expected to be a list with an even number of elements
+representing \fIoption\fR and \fIvalue\fR arguments to pass
+to \fBtest\fR.  However, these values are not passed directly, as
+in the alternate forms of \fBswitch\fR.  Instead, this form makes
+an unfortunate attempt to overthrow Tcl's substitution rules by
+performing substitutions on some of the list elements as an attempt to
+implement a
+.QW "do what I mean"
+interpretation of a brace-enclosed
+.QW block .
+The result is nearly impossible to document clearly, and
+for that reason this form is not recommended.  See the examples in
+\fBCREATING TEST SUITES WITH TCLTEST\fR below to see that this
+form is really not necessary to avoid backslash-quoted newlines.
+If you insist on using this form, examine
+the source code of \fBtcltest\fR if you want to know the substitution
+details, or just enclose the third through last argument
+to \fBtest\fR in braces and hope for the best.
+.TP
+\fBworkingDirectory\fR ?\fIdirectoryName\fR?
+.
+Sets or returns the current working directory when the test suite is
+running.  The default value for workingDirectory is the directory in
+which the test suite was launched.  The Tcl commands \fBcd\fR and
+\fBpwd\fR are sufficient replacements.
+.TP
+\fBnormalizeMsg \fImsg\fR
+.
+Returns the result of removing the
+.QW extra
+newlines from \fImsg\fR, where
+.QW extra
+is rather imprecise.  Tcl offers plenty of string
+processing commands to modify strings as you wish, and
+\fBcustomMatch\fR allows flexible matching of actual and expected
+results.
+.TP
+\fBnormalizePath \fIpathVar\fR
+.
+Resolves symlinks in a path, thus creating a path without internal
+redirection.  It is assumed that \fIpathVar\fR is absolute.
+\fIpathVar\fR is modified in place.  The Tcl command \fBfile normalize\fR
+is a sufficient replacement.
+.TP
+\fBbytestring \fIstring\fR
+.
+Construct a string that consists of the requested sequence of bytes,
+as opposed to a string of properly formed UTF-8 characters using the
+value supplied in \fIstring\fR.  This allows the tester to create
+denormalized or improperly formed strings to pass to C procedures that
+are supposed to accept strings with embedded NULL types and confirm
+that a string result has a certain pattern of bytes.  This is
+exactly equivalent to the Tcl command \fBencoding convertfrom\fR
+\fBidentity\fR.
+.SH TESTS
+.PP
+The \fBtest\fR command is the heart of the \fBtcltest\fR package.
+Its essential function is to evaluate a Tcl script and compare
+the result with an expected result.  The options of \fBtest\fR
+define the test script, the environment in which to evaluate it,
+the expected result, and how the compare the actual result to
+the expected result.  Some configuration options of \fBtcltest\fR
+also influence how \fBtest\fR operates.
+.PP
+The valid options for \fBtest\fR are summarized:
+.PP
+.CS
+\fBtest\fR \fIname\fR \fIdescription\fR
+        ?\fB\-constraints \fIkeywordList|expression\fR?
+        ?\fB\-setup \fIsetupScript\fR?
+        ?\fB\-body \fItestScript\fR?
+        ?\fB\-cleanup \fIcleanupScript\fR?
+        ?\fB\-result \fIexpectedAnswer\fR?
+        ?\fB\-output \fIexpectedOutput\fR?
+        ?\fB\-errorOutput \fIexpectedError\fR?
+        ?\fB\-returnCodes \fIcodeList\fR?
+        ?\fB\-match \fImode\fR?
+.CE
+.PP
+The \fIname\fR may be any string.  It is conventional to choose
+a \fIname\fR according to the pattern:
+.PP
+.CS
+\fItarget\fR-\fImajorNum\fR.\fIminorNum\fR
+.CE
+.PP
+For white-box (regression) tests, the target should be the name of the
+C function or Tcl procedure being tested.  For black-box tests, the
+target should be the name of the feature being tested.  Some conventions
+call for the names of black-box tests to have the suffix \fB_bb\fR.
+Related tests should share a major number.  As a test suite evolves,
+it is best to have the same test name continue to correspond to the
+same test, so that it remains meaningful to say things like
+.QW "Test foo-1.3 passed in all releases up to 3.4, but began failing in release 3.5."
+.PP
+During evaluation of \fBtest\fR, the \fIname\fR will be compared
+to the lists of string matching patterns returned by
+\fBconfigure \-match\fR, and \fBconfigure \-skip\fR.  The test
+will be run only if \fIname\fR matches any of the patterns from
+\fBconfigure \-match\fR and matches none of the patterns
+from \fBconfigure \-skip\fR.
+.PP
+The \fIdescription\fR should be a short textual description of the
+test.  The \fIdescription\fR is included in output produced by the
+test, typically test failure messages.  Good \fIdescription\fR values
+should briefly explain the purpose of the test to users of a test suite.
+The name of a Tcl or C function being tested should be included in the
+description for regression tests.  If the test case exists to reproduce
+a bug, include the bug ID in the description. 
+.PP
+Valid attributes and associated values are:
+.TP
+\fB\-constraints \fIkeywordList\fR|\fIexpression\fR
+.
+The optional \fB\-constraints\fR attribute can be list of one or more
+keywords or an expression.  If the \fB\-constraints\fR value is a list of
+keywords, each of these keywords should be the name of a constraint
+defined by a call to \fBtestConstraint\fR.  If any of the listed
+constraints is false or does not exist, the test is skipped.  If the
+\fB\-constraints\fR value is an expression, that expression
+is evaluated. If the expression evaluates to true, then the test is run.
+Note that the expression form of \fB\-constraints\fR may interfere with the
+operation of \fBconfigure \-constraints\fR and
+\fBconfigure \-limitconstraints\fR, and is not recommended.
+Appropriate constraints should be added to any tests that should
+not always be run.  That is, conditional evaluation of a test
+should be accomplished by the \fB\-constraints\fR option, not by
+conditional evaluation of \fBtest\fR.  In that way, the same
+number of tests are always reported by the test suite, though
+the number skipped may change based on the testing environment.
+The default value is an empty list.  
+See \fBTEST CONSTRAINTS\fR below for a list of built-in constraints 
+and information on how to add your own constraints.
+.TP
+\fB\-setup \fIscript\fR
+.
+The optional \fB\-setup\fR attribute indicates a \fIscript\fR that will be run
+before the script indicated by the \fB\-body\fR attribute.  If evaluation
+of \fIscript\fR raises an error, the test will fail.  The default value
+is an empty script.
+.TP
+\fB\-body \fIscript\fR
+.
+The \fB\-body\fR attribute indicates the \fIscript\fR to run to carry out the 
+test, which must return a result that can be checked for correctness.
+If evaluation of \fIscript\fR raises an error, the test will fail
+(unless the \fB\-returnCodes\fR option is used to state that an error
+is expected).
+The default value is an empty script.
+.TP
+\fB\-cleanup \fIscript\fR
+.
+The optional \fB\-cleanup\fR attribute indicates a \fIscript\fR that will be
+run after the script indicated by the \fB\-body\fR attribute.
+If evaluation of \fIscript\fR raises an error, the test will fail.
+The default value is an empty script.
+.TP
+\fB\-match \fImode\fR
+.
+The \fB\-match\fR attribute determines how expected answers supplied by
+\fB\-result\fR, \fB\-output\fR, and \fB\-errorOutput\fR are compared.  Valid
+values for \fImode\fR are \fBregexp\fR, \fBglob\fR, \fBexact\fR, and
+any value registered by a prior call to \fBcustomMatch\fR.  The default
+value is \fBexact\fR.
+.TP
+\fB\-result \fIexpectedValue\fR
+.
+The \fB\-result\fR attribute supplies the \fIexpectedValue\fR against which
+the return value from script will be compared. The default value is
+an empty string.
+.TP
+\fB\-output \fIexpectedValue\fR
+.
+The \fB\-output\fR attribute supplies the \fIexpectedValue\fR against which
+any output sent to \fBstdout\fR or \fBoutputChannel\fR during evaluation
+of the script(s) will be compared.  Note that only output printed using
+the global \fBputs\fR command is used for comparison.  If \fB\-output\fR is
+not specified, output sent to \fBstdout\fR and \fBoutputChannel\fR is not
+processed for comparison.
+.TP
+\fB\-errorOutput \fIexpectedValue\fR
+.
+The \fB\-errorOutput\fR attribute supplies the \fIexpectedValue\fR against
+which any output sent to \fBstderr\fR or \fBerrorChannel\fR during 
+evaluation of the script(s) will be compared. Note that only output
+printed using the global \fBputs\fR command is used for comparison.  If
+\fB\-errorOutput\fR is not specified, output sent to \fBstderr\fR and
+\fBerrorChannel\fR is not processed for comparison.
+.TP
+\fB\-returnCodes \fIexpectedCodeList\fR
+.
+The optional \fB\-returnCodes\fR attribute supplies \fIexpectedCodeList\fR,
+a list of return codes that may be accepted from evaluation of the
+\fB\-body\fR script.  If evaluation of the \fB\-body\fR script returns
+a code not in the \fIexpectedCodeList\fR, the test fails.  All
+return codes known to \fBreturn\fR, in both numeric and symbolic
+form, including extended return codes, are acceptable elements in
+the \fIexpectedCodeList\fR.  Default value is
+.QW "\fBok return\fR" .
+.PP
+To pass, a test must successfully evaluate its \fB\-setup\fR, \fB\-body\fR,
+and \fB\-cleanup\fR scripts.  The return code of the \fB\-body\fR script and
+its result must match expected values, and if specified, output and error
+data from the test must match expected \fB\-output\fR and \fB\-errorOutput\fR
+values.  If any of these conditions are not met, then the test fails.
+Note that all scripts are evaluated in the context of the caller
+of \fBtest\fR.
+.PP
+As long as \fBtest\fR is called with valid syntax and legal
+values for all attributes, it will not raise an error.  Test
+failures are instead reported as output written to \fBoutputChannel\fR.
+In default operation, a successful test produces no output.  The output
+messages produced by \fBtest\fR are controlled by the
+\fBconfigure \-verbose\fR option as described in \fBCONFIGURABLE OPTIONS\fR
+below.  Any output produced by the test scripts themselves should be
+produced using \fBputs\fR to \fBoutputChannel\fR or
+\fBerrorChannel\fR, so that users of the test suite may
+easily capture output with the \fBconfigure \-outfile\fR and
+\fBconfigure \-errfile\fR options, and so that the \fB\-output\fR
+and \fB\-errorOutput\fR attributes work properly.
+.SS "TEST CONSTRAINTS"
+.PP
+Constraints are used to determine whether or not a test should be skipped.
+Each constraint has a name, which may be any string, and a boolean
+value.  Each \fBtest\fR has a \fB\-constraints\fR value which is a
+list of constraint names.  There are two modes of constraint control.
+Most frequently, the default mode is used, indicated by a setting
+of \fBconfigure \-limitconstraints\fR to false.  The test will run
+only if all constraints in the list are true-valued.  Thus,
+the \fB\-constraints\fR option of \fBtest\fR is a convenient, symbolic
+way to define any conditions required for the test to be possible or
+meaningful.  For example, a \fBtest\fR with \fB\-constraints unix\fR
+will only be run if the constraint \fBunix\fR is true, which indicates
+the test suite is being run on a Unix platform.
+.PP
+Each \fBtest\fR should include whatever \fB\-constraints\fR are
+required to constrain it to run only where appropriate.  Several
+constraints are pre-defined in the \fBtcltest\fR package, listed
+below.  The registration of user-defined constraints is performed
+by the \fBtestConstraint\fR command.  User-defined constraints
+may appear within a test file, or within the script specified
+by the \fBconfigure \-load\fR or \fBconfigure \-loadfile\fR
+options.
+.PP
+The following is a list of constraints pre-defined by the
+\fBtcltest\fR package itself:
+.TP
+\fIsingleTestInterp\fR

+.
+This test can not be run on Windows.  This flag is used to temporarily
+disable a test. 
+.TP
+\fItempNotMac\fR
+.
+This test can not be run on a Mac.  This flag is used
+to temporarily disable a test.
+.TP
+\fIunixCrash\fR
+.
+This test crashes if it is run on Unix.  This flag is used to temporarily
+disable a test. 
+.TP
+\fIwinCrash\fR
+.
+This test crashes if it is run on Windows.  This flag is used to temporarily
+disable a test. 
+.TP
+\fImacCrash\fR
+.
+This test crashes if it is run on a Mac.  This flag is used to temporarily
+disable a test. 
+.TP
+\fIemptyTest\fR
+.
+This test is empty, and so not worth running, but it remains as a
+place-holder for a test to be written in the future.  This constraint
+has value false to cause tests to be skipped unless the user specifies
+otherwise.
+.TP
+\fIknownBug\fR
+.
+This test is known to fail and the bug is not yet fixed.  This constraint
+has value false to cause tests to be skipped unless the user specifies
+otherwise.
+.TP
+\fInonPortable\fR
+.
+This test can only be run in some known development environment.
+Some tests are inherently non-portable because they depend on things
+like word length, file system configuration, window manager, etc.
+This constraint has value false to cause tests to be skipped unless
+the user specifies otherwise.  
+.TP
+\fIuserInteraction\fR
+.
+This test requires interaction from the user.  This constraint has
+value false to causes tests to be skipped unless the user specifies
+otherwise.  
+.TP
+\fIinteractive\fR
+.
+This test can only be run in if the interpreter is in interactive mode 
+(when the global tcl_interactive variable is set to 1).
+.TP
+\fInonBlockFiles\fR
+.
+This test can only be run if platform supports setting files into
+nonblocking mode.
+.TP
+\fIasyncPipeClose\fR
+.
+This test can only be run if platform supports async flush and async close
+on a pipe.
+.TP
+\fIunixExecs\fR
+.
+This test can only be run if this machine has Unix-style commands
+\fBcat\fR, \fBecho\fR, \fBsh\fR, \fBwc\fR, \fBrm\fR, \fBsleep\fR,
+\fBfgrep\fR, \fBps\fR, \fBchmod\fR, and \fBmkdir\fR available.
+.TP
+\fIhasIsoLocale\fR
+.
+This test can only be run if can switch to an ISO locale.
+.TP
+\fIroot\fR
+.
+This test can only run if Unix user is root.
+.TP
+\fInotRoot\fR
+.
+This test can only run if Unix user is not root.
+.TP
+\fIeformat\fR
+.
+This test can only run if app has a working version of sprintf with respect
+to the
+.QW e
+format of floating-point numbers.
+.TP
+\fIstdio\fR
+.
+This test can only be run if \fBinterpreter\fR can be \fBopen\fRed
+as a pipe.
+.PP
+The alternative mode of constraint control is enabled by setting
+\fBconfigure \-limitconstraints\fR to true.  With that configuration
+setting, all existing constraints other than those in the constraint
+list returned by \fBconfigure \-constraints\fR are set to false.
+When the value of \fBconfigure \-constraints\fR
+is set, all those constraints are set to true.  The effect is that
+when both options \fBconfigure \-constraints\fR and
+\fBconfigure \-limitconstraints\fR are in use, only those tests including
+only constraints from the \fBconfigure \-constraints\fR list
+are run; all others are skipped.  For example, one might set
+up a configuration with
+.PP
+.CS
+\fBconfigure\fR -constraints knownBug \e
+          -limitconstraints true \e
+          -verbose pass
+.CE
+.PP
+to run exactly those tests that exercise known bugs, and discover
+whether any of them pass, indicating the bug had been fixed.
+.SS "RUNNING ALL TESTS"
+.PP
+The single command \fBrunAllTests\fR is evaluated to run an entire
+test suite, spanning many files and directories.  The configuration
+options of \fBtcltest\fR control the precise operations.  The
+\fBrunAllTests\fR command begins by printing a summary of its
+configuration to \fBoutputChannel\fR.
+.PP
+Test files to be evaluated are sought in the directory
+\fBconfigure \-testdir\fR.  The list of files in that directory
+that match any of the patterns in \fBconfigure \-file\fR and
+match none of the patterns in \fBconfigure \-notfile\fR is generated
+and sorted.  Then each file will be evaluated in turn.  If
+\fBconfigure \-singleproc\fR is true, then each file will
+be \fBsource\fRd in the caller's context.  If it is false,
+then a copy of \fBinterpreter\fR will be \fBexec\fR'd to
+evaluate each file.  The multi-process operation is useful
+when testing can cause errors so severe that a process 
+terminates.  Although such an error may terminate a child
+process evaluating one file, the master process can continue
+with the rest of the test suite.  In multi-process operation,
+the configuration of \fBtcltest\fR in the master process is
+passed to the child processes as command line arguments,
+with the exception of \fBconfigure \-outfile\fR.  The
+\fBrunAllTests\fR command in the
+master process collects all output from the child processes
+and collates their results into one master report.  Any
+reports of individual test failures, or messages requested
+by a \fBconfigure \-verbose\fR setting are passed directly
+on to \fBoutputChannel\fR by the master process.
+.PP
+After evaluating all selected test files, a summary of the
+results is printed to \fBoutputChannel\fR.  The summary
+includes the total number of \fBtest\fRs evaluated, broken
+down into those skipped, those passed, and those failed.
+The summary also notes the number of files evaluated, and the names
+of any files with failing tests or errors.  A list of
+the constraints that caused tests to be skipped, and the
+number of tests skipped for each is also printed.  Also,
+messages are printed if it appears that evaluation of
+a test file has caused any temporary files to be left
+behind in \fBconfigure \-tmpdir\fR.
+.PP
+Having completed and summarized all selected test files,
+\fBrunAllTests\fR then recursively acts on subdirectories
+of \fBconfigure \-testdir\fR.  All subdirectories that
+match any of the patterns in \fBconfigure \-relateddir\fR
+and do not match any of the patterns in
+\fBconfigure \-asidefromdir\fR are examined.  If
+a file named \fBall.tcl\fR is found in such a directory,
+it will be \fBsource\fRd in the caller's context.
+Whether or not an examined directory contains an
+\fBall.tcl\fR file, its subdirectories are also scanned
+against the \fBconfigure \-relateddir\fR and
+\fBconfigure \-asidefromdir\fR patterns.  In this way,
+many directories in a directory tree can have all their
+test files evaluated by a single \fBrunAllTests\fR
+command.
+.SH "CONFIGURABLE OPTIONS"
+The \fBconfigure\fR command is used to set and query the configurable
+options of \fBtcltest\fR.  The valid options are:
+.TP
+\fB\-singleproc \fIboolean\fR
+.
+Controls whether or not \fBrunAllTests\fR spawns a child process for
+each test file.  No spawning when \fIboolean\fR is true.  Default
+value is false.
+.TP
+\fB\-debug \fIlevel\fR
+.
+Sets the debug level to \fIlevel\fR, an integer value indicating how
+much debugging information should be printed to \fBstdout\fR.  Note that
+debug messages always go to \fBstdout\fR, independent of the value of
+\fBconfigure \-outfile\fR.  Default value is 0.  Levels are defined as:
+.RS
+.IP 0 4
+Do not display any debug information.
+.IP 1
+Display information regarding whether a test is skipped because it
+does not match any of the tests that were specified using by
+\fBconfigure \-match\fR (userSpecifiedNonMatch) or matches any of
+the tests specified by \fBconfigure \-skip\fR (userSpecifiedSkip).  Also
+print warnings about possible lack of cleanup or balance in test files.
+Also print warnings about any re-use of test names.

+.RE
+.TP
+\fB\-preservecore \fIlevel\fR
+.
+Sets the core preservation level to \fIlevel\fR.  This level
+determines how stringent checks for core files are.  Default
+value is 0.  Levels are defined as:

+.PP
+At the next higher layer of organization, several \fBtest\fR commands
+are gathered together into a single test file.  Test files should have
+names with the
+.QW \fB.test\fR
+extension, because that is the default pattern
+used by \fBrunAllTests\fR to find test files.  It is a good rule of
+thumb to have one test file for each source code file of your project.
+It is good practice to edit the test file and the source code file
+together, keeping tests synchronized with code changes.

+Use the \fB\-setup\fR and \fB\-cleanup\fR options to establish and release
+all context requirements of the test body.  Do not make tests depend on
+prior tests in the file.  Those prior tests might be skipped.  If several
+consecutive tests require the same context, the appropriate setup
+and cleanup scripts may be stored in variable for passing to each tests
+\fB\-setup\fR and \fB\-cleanup\fR options.  This is a better solution than
+performing setup outside of \fBtest\fR commands, because the setup will
+only be done if necessary, and any errors during setup will be reported,
+and not cause the test file to abort.
+.PP
+A test file should be able to be combined with other test files and not
+interfere with them, even when \fBconfigure \-singleproc 1\fR causes
+all files to be evaluated in a common interpreter.  A simple way to
+achieve this is to have your tests define all their commands and variables
+in a namespace that is deleted when the test file evaluation is complete.
+A good namespace to use is a child namespace \fBtest\fR of the namespace
+of the module you are testing.
+.PP
+A test file should also be able to be evaluated directly as a script,
+not depending on being called by a master \fBrunAllTests\fR.  This
+means that each test file should process command line arguments to give
+the tester all the configuration control that \fBtcltest\fR provides.
+.PP
+After all \fBtest\fRs in a test file, the command \fBcleanupTests\fR
+should be called.

+.SH COMPATIBILITY
+.PP
+A number of commands and variables in the \fB::tcltest\fR namespace
+provided by earlier releases of \fBtcltest\fR have not been documented
+here.  They are no longer part of the supported public interface of
+\fBtcltest\fR and should not be used in new test suites.  However,
+to continue to support existing test suites written to the older
+interface specifications, many of those deprecated commands and
+variables still work as before.  For example, in many circumstances,
+\fBconfigure\fR will be automatically called shortly after
+\fBpackage require\fR \fBtcltest 2.1\fR succeeds with arguments
+from the variable \fB::argv\fR.  This is to support test suites
+that depend on the old behavior that \fBtcltest\fR was automatically

+.SH "KNOWN ISSUES"
+There are two known issues related to nested evaluations of \fBtest\fR.
+The first issue relates to the stack level in which test scripts are
+executed.  Tests nested within other tests may be executed at the same
+stack level as the outermost test.  For example, in the following code: 
+.PP
+.CS
+\fBtest\fR level-1.1 {level 1} {
+    -body {
+        \fBtest\fR level-2.1 {level 2} {
+        }
+    }
+}
+.CE
+.PP
+any script executed in level-2.1 may be executed at the same stack
+level as the script defined for level-1.1.  
+.PP
+In addition, while two \fBtest\fRs have been run, results will only
+be reported by \fBcleanupTests\fR for tests at the same level as
+test level-1.1.  However, test results for all tests run prior to
+level-1.1 will be available when test level-2.1 runs.  What this
+means is that if you try to access the test results for test level-2.1,
+it will may say that
+.QW m
+tests have run,
+.QW n
+tests have been skipped,
+.QW o
+tests have passed and
+.QW p
+tests have failed, where
+.QW m ,
+.QW n ,
+.QW o ,
+and
+.QW p
+refer to tests that were run at the same test level as test level-1.1.
+.PP
+Implementation of output and error comparison in the test command
+depends on usage of \fBputs\fR in your application code.  Output is
+intercepted by redefining the global \fBputs\fR command while the defined test
+script is being run.  Errors thrown by C procedures or printed
+directly from C applications will not be caught by the \fBtest\fR command.
+Therefore, usage of the \fB\-output\fR and \fB\-errorOutput\fR
+options to \fBtest\fR is useful only for pure Tcl applications
+that use \fBputs\fR to produce output.

+Reading an element will return the value of the corresponding
+environment variable.
+Setting an element of the array will modify the corresponding
+environment variable or create a new one if it does not already
+exist.
+Unsetting an element of \fBenv\fR will remove the corresponding
+environment variable.
+Changes to the \fBenv\fR array will affect the environment
+passed to children by commands like \fBexec\fR.
+If the entire \fBenv\fR array is unset then Tcl will stop
+monitoring \fBenv\fR accesses and will not update environment
+variables.
+.RS
+.PP
+Under Windows, the environment variables PATH and COMSPEC in any
+capitalization are converted automatically to upper case.  For instance, the
+PATH variable could be exported by the operating system as
+.QW path ,
+.QW Path ,
+.QW PaTh ,
+etc., causing otherwise simple Tcl code to have to
+support many special cases.  All other environment variables inherited by
+Tcl are left unmodified.  Setting an env array variable to blank is the
+same as unsetting it as this is the behavior of the underlying Windows OS.
+It should be noted that relying on an existing and empty environment variable
+will not work on Windows and is discouraged for cross-platform usage.
+.PP
+The following elements of \fBenv\fR are special to Tcl:
+.TP
+\fBenv(HOME)\fR
+.
+This environment variable, if set, gives the location of the directory
+considered to be the current user's home directory, and to which a
+call of \fBcd\fR without arguments or with just
+.QW ~
+as an argument will change into. Most platforms set this correctly by
+default; it does not normally need to be set by user code.
+.TP
+\fBenv(TCL_LIBRARY)\fR
+.
+If set, then it specifies the location of the directory containing
+library scripts (the value of this variable will be
+assigned to the \fBtcl_library\fR variable and therefore returned by
+the command \fBinfo library\fR).  If this variable is not set then
+a default value is used.
+.RS
+.PP
+Note that this environment variable should \fInot\fR normally be set.
+.RE
+.TP
+\fBenv(TCLLIBPATH)\fR
+.
+If set, then it must contain a valid Tcl list giving directories to
+search during auto-load operations.  Directories must be specified in 
+Tcl format, using
+.QW /
+as the path separator, regardless of platform.
+This variable is only used when initializing the \fBauto_path\fR variable.
+.TP
+\fBenv(TCL_TZ)\fR, \fBenv(TZ)\fR
+.
+These specify the default timezone used for parsing and formatting times and
+dates in the \fBclock\fR command. On many platforms, the TZ environment
+variable is set up by the operating system.
+.TP
+\fBenv(LC_ALL)\fR, \fBenv(LC_MESSAGES)\fR, \fBenv(LANG)\fR
+.
+These environment variables are used by the \fBmsgcat\fR package to
+determine what locale to format messages using.
+.TP
+\fBenv(TCL_INTERP_DEBUG_FRAME)\fR
+.
+If existing, it has the same effect as running \fBinterp debug\fR
+\fB{} -frame 1\fR
+as the very first command of each new Tcl interpreter.
+.RE
+.TP
+\fBerrorCode\fR
+.
+This variable holds the value of the \fB\-errorcode\fR return option
+set by the most recent error that occurred in this interpreter.
+This list value represents additional information about the error
+in a form that is easy to process with programs.
+The first element of the list identifies a general class of
+errors, and determines the format of the rest of the list.
+The following formats for \fB\-errorcode\fR return options
+are used by the Tcl core; individual applications may define
+additional formats.
+.RS
+.TP
+\fBARITH\fI code msg\fR
+.
+This format is used when an arithmetic error occurs (e.g. an attempt
+to divide zero by zero in the \fBexpr\fR command).
+\fICode\fR identifies the precise error and \fImsg\fR provides a
+human-readable description of the error.  \fICode\fR will be either
+DIVZERO (for an attempt to divide by zero),
+DOMAIN (if an argument is outside the domain of a function, such as acos(\-3)),
+IOVERFLOW (for integer overflow),
+OVERFLOW (for a floating-point overflow),
+or UNKNOWN (if the cause of the error cannot be determined).
+.RS
+.PP
+Detection of these errors depends in part on the underlying hardware
+and system libraries.
+.RE
+.TP
+\fBCHILDKILLED\fI pid sigName msg\fR
+.
+This format is used when a child process has been killed because of
+a signal.  The \fIpid\fR element will be the process's identifier (in decimal).
+The \fIsigName\fR element will be the symbolic name of the signal that caused
+the process to terminate; it will be one of the names from the
+include file signal.h, such as \fBSIGPIPE\fR.
+The \fImsg\fR element will be a short human-readable message
+describing the signal, such as
+.QW "write on pipe with no readers"
+for \fBSIGPIPE\fR.
+.TP
+\fBCHILDSTATUS\fI pid code\fR
+.
+This format is used when a child process has exited with a non-zero
+exit status.  The \fIpid\fR element will be the
+process's identifier (in decimal) and the \fIcode\fR element will be the exit
+code returned by the process (also in decimal).
+.TP
+\fBCHILDSUSP\fI pid sigName msg\fR
+.
+This format is used when a child process has been suspended because
+of a signal.
+The \fIpid\fR element will be the process's identifier, in decimal.
+The \fIsigName\fR element will be the symbolic name of the signal that caused
+the process to suspend; this will be one of the names from the
+include file signal.h, such as \fBSIGTTIN\fR.
+The \fImsg\fR element will be a short human-readable message
+describing the signal, such as
+.QW "background tty read"
+for \fBSIGTTIN\fR.
+.TP
+\fBNONE\fR
+.
+This format is used for errors where no additional information is
+available for an error besides the message returned with the
+error.  In these cases the \fB\-errorcode\fR return option
+will consist of a list containing a single element whose
+contents are \fBNONE\fR.
+.TP
+\fBPOSIX \fIerrName msg\fR
+.
+If the first element is \fBPOSIX\fR, then
+the error occurred during a POSIX kernel call.
+The \fIerrName\fR element will contain the symbolic name
+of the error that occurred, such as \fBENOENT\fR; this will
+be one of the values defined in the include file errno.h.
+The \fImsg\fR element will be a human-readable
+message corresponding to \fIerrName\fR, such as
+.QW "no such file or directory"
+for the \fBENOENT\fR case.
+.TP
+\fBTCL\fR ...
+.
+Indicates some sort of problem generated in relation to Tcl itself, e.g. a
+failure to look up a channel or variable.
+.PP
+To set the \fB\-errorcode\fR return option, applications should use library
+procedures such as \fBTcl_SetObjErrorCode\fR, \fBTcl_SetReturnOptions\fR,
+and \fBTcl_PosixError\fR, or they may invoke the \fB\-errorcode\fR
+option of the \fBreturn\fR command.
+If none of these methods for setting the error code has been used,
+the Tcl interpreter will reset the variable to \fBNONE\fR after
+the next error.
+.RE
+.TP
+\fBerrorInfo\fR
+.
+This variable holds the value of the \fB\-errorinfo\fR return option
+set by the most recent error that occurred in this interpreter.
+This string value will contain one or more lines
+identifying the Tcl commands and procedures that were being executed
+when the most recent error occurred.
+Its contents take the form of a stack trace showing the various
+nested Tcl commands that had been invoked at the time of the error.
+.TP
+\fBtcl_library\fR
+.
+This variable holds the name of a directory containing the
+system library of Tcl scripts, such as those used for auto-loading.
+The value of this variable is returned by the \fBinfo library\fR command.
+See the \fBlibrary\fR manual entry for details of the facilities 
+provided by the Tcl script library.
+Normally each application or package will have its own application-specific
+script library in addition to the Tcl script library;
+each application should set a global variable with a name like
+\fB$\fIapp\fB_library\fR (where \fIapp\fR is the application's name)
+to hold the network file name for that application's library directory.
+The initial value of \fBtcl_library\fR is set when an interpreter
+is created by searching several different directories until one is
+found that contains an appropriate Tcl startup script.
+If the \fBTCL_LIBRARY\fR environment variable exists, then
+the directory it names is checked first.
+If \fBTCL_LIBRARY\fR is not set or doesn't refer to an appropriate
+directory, then Tcl checks several other directories based on a
+compiled-in default location, the location of the binary containing
+the application, and the current working directory.
+.TP
+\fBtcl_patchLevel\fR
+.
+When an interpreter is created Tcl initializes this variable to
+hold a string giving the current patch level for Tcl, such as
+\fB8.4.16\fR for Tcl 8.4 with the first sixteen official patches, or
+\fB8.5b3\fR for the third beta release of Tcl 8.5.
+The value of this variable is returned by the \fBinfo patchlevel\fR
+command.
+.TP
+\fBtcl_pkgPath\fR
+.
+This variable holds a list of directories indicating where packages are
+normally installed.  It is not used on Windows.  It typically contains
+either one or two entries; if it contains two entries, the first is
+normally a directory for platform-dependent packages (e.g., shared library
+binaries) and the second is normally a directory for platform-independent
+packages (e.g., script files). Typically a package is installed as a
+subdirectory of one of the entries in the \fBtcl_pkgPath\fR
+variable. The directories in the \fBtcl_pkgPath\fR variable are
+included by default in the \fBauto_path\fR
+variable, so they and their immediate subdirectories are automatically
+searched for packages during \fBpackage require\fR commands.  Note:
+\fBtcl_pkgPath\fR is not intended to be modified by the application.  Its
+value is added to \fBauto_path\fR at startup; changes to \fBtcl_pkgPath\fR
+are not reflected in \fBauto_path\fR.  If you want Tcl to search additional
+directories for packages you should add the names of those directories to
+\fBauto_path\fR, not \fBtcl_pkgPath\fR.
+.TP
+\fBtcl_platform\fR
+.
+This is an associative array whose elements contain information about
+the platform on which the application is running, such as the name of
+the operating system, its current release number, and the machine's
+instruction set.  The elements listed below will always
+be defined, but they may have empty strings as values if Tcl could not
+retrieve any relevant information.  In addition, extensions
+and applications may add additional values to the array.  The
+predefined elements are:
+.RS
+.TP
+\fBbyteOrder\fR
+.
+The native byte order of this machine: either \fBlittleEndian\fR or
+\fBbigEndian\fR. 
+.TP
+\fBdebug\fR
+.
+If this variable exists, then the interpreter was compiled with and linked
+to a debug-enabled C run-time.  This variable will only exist on Windows,
+so extension writers can specify which package to load depending on the
+C run-time library that is in use.  This is not an indication that this core
+contains symbols.
+.TP
+\fBmachine\fR
+.
+The instruction set executed by this machine, such as
+\fBintel\fR, \fBPPC\fR, \fB68k\fR, or \fBsun4m\fR.  On UNIX machines, this
+is the value returned by \fBuname -m\fR.
+.TP
+\fBos\fR
+.
+The name of the operating system running on this machine,
+such as \fBWindows 95\fR, \fBWindows NT\fR, or \fBSunOS\fR.
+On UNIX machines, this is the value returned by \fBuname -s\fR.
+On Windows 95 and Windows 98, the value returned will be \fBWindows
+95\fR to provide better backwards compatibility to Windows 95; to
+distinguish between the two, check the \fBosVersion\fR.
+.TP
+\fBosVersion\fR
+.
+The version number for the operating system running on this machine.
+On UNIX machines, this is the value returned by \fBuname -r\fR.  On
+Windows 95, the version will be 4.0; on Windows 98, the version will
+be 4.10.
+.TP
+\fBpathSeparator\fR
+.VS 8.6
+'\" Defined by TIP #315
+The character that should be used to \fBsplit\fR PATH-like environment
+variables into their corresponding list of directory names.
+.VE 8.6
+.TP
+\fBplatform\fR
+.
+Either \fBwindows\fR, or \fBunix\fR.  This identifies the
+general operating environment of the machine.
+.TP
+\fBpointerSize\fR
+.
+This gives the size of the native-machine pointer in bytes (strictly, it
+is same as the result of evaluating \fIsizeof(void*)\fR in C.)
+.TP
+\fBthreaded\fR
+.
+If this variable exists, then the interpreter
+was compiled with threads enabled.
+.TP
+\fBuser\fR
+.
+This identifies the
+current user based on the login information available on the platform.
+This comes from the USER or LOGNAME environment variable on Unix,

+\fBwordSize\fR
+.
+This gives the size of the native-machine word in bytes (strictly, it
+is same as the result of evaluating \fIsizeof(long)\fR in C.)
+.RE
+.TP
+\fBtcl_precision\fR
+.
+This variable controls the number of digits to generate
+when converting floating-point values to strings.  It defaults
+to 0.  \fIApplications should not change this value;\fR it is
+provided for compatibility with legacy code.
+.PP
+.RS
+The default value of 0 is special, meaning that Tcl should
+convert numbers using as few digits as possible while still
+distinguishing any floating point number from its nearest
+neighbours.  It differs from using an arbitrarily high value
+for \fItcl_precision\fR in that an inexact number like \fI1.4\fR
+will convert as \fI1.4\fR rather than \fI1.3999999999999999\fR
+even though the latter is nearer to the exact value of the
+binary number.
+.RE
+.PP
+.RS
+If \fBtcl_precision\fR is not zero, then when Tcl converts a floating
+point number, it creates a decimal representation of at most 
+\fBtcl_precision\fR significant digits; the result may be shorter if
+the shorter result represents the original number exactly. If no
+result of at most \fBtcl_precision\fR digits is an exact representation
+of the original number, the one that is closest to the original
+number is chosen.
+If the original number lies precisely between two equally accurate
+decimal representations, then the one with an even value for the least
+significant digit is chosen; for instance, if \fBtcl_precision\fR is 3, then
+0.3125 will convert to 0.312, not 0.313, while 0.6875 will convert to
+0.688, not 0.687. Any string of trailing zeroes that remains is trimmed.
+.RE
+.PP
+.RS
+a \fBtcl_precision\fR value of 17 digits is
+.QW perfect
+for IEEE floating-point in that it allows
+double-precision values to be converted to strings and back to
+binary with no loss of information. For this reason, you will often
+see it as a value in legacy code that must run on Tcl versions before
+8.5. It is no longer recommended; as noted above, a zero value is the
+preferred method.
+.RE
+.PP
+.RS
+All interpreters in a thread share a single \fBtcl_precision\fR value:
+changing it in one interpreter will affect all other interpreters as
+well.  Safe interpreters are not allowed to modify the
+variable.
+.RE
+.PP
+.RS
+Valid values for \fBtcl_precision\fR range from 0 to 17.

+.TP
+\fBtcl_rcFileName\fR
+.
+This variable is used during initialization to indicate the name of a
+user-specific startup file.  If it is set by application-specific
+initialization, then the Tcl startup code will check for the existence
+of this file and \fBsource\fR it if it exists.  For example, for \fBwish\fR
+the variable is set to \fB~/.wishrc\fR for Unix and \fB~/wishrc.tcl\fR
+for Windows.
+.TP
+\fBtcl_traceCompile\fR
+.
+The value of this variable can be set to control
+how much tracing information
+is displayed during bytecode compilation.
+By default, \fBtcl_traceCompile\fR is zero and no information is displayed.
+Setting \fBtcl_traceCompile\fR to 1 generates a one-line summary in \fBstdout\fR
+whenever a procedure or top-level command is compiled.
+Setting it to 2 generates a detailed listing in \fBstdout\fR of the
+bytecode instructions emitted during every compilation.
+This variable is useful in
+tracking down suspected problems with the Tcl compiler.
+.PP
+.RS
+This variable and functionality only exist if
+\fBTCL_COMPILE_DEBUG\fR was defined during Tcl's compilation.
+.RE
+.TP
+\fBtcl_traceExec\fR
+.
+The value of this variable can be set to control
+how much tracing information
+is displayed during bytecode execution.
+By default, \fBtcl_traceExec\fR is zero and no information is displayed.
+Setting \fBtcl_traceExec\fR to 1 generates a one-line trace in \fBstdout\fR
+on each call to a Tcl procedure.
+Setting it to 2 generates a line of output
+whenever any Tcl command is invoked
+that contains the name of the command and its arguments.
+Setting it to 3 produces a detailed trace showing the result of
+executing each bytecode instruction.
+Note that when \fBtcl_traceExec\fR is 2 or 3,
+commands such as \fBset\fR and \fBincr\fR
+that have been entirely replaced by a sequence
+of bytecode instructions are not shown.
+Setting this variable is useful in

+\fBargc\fR
+.
+The number of arguments to \fBtclsh\fR or \fBwish\fR.
+.TP 6
+\fBargv\fR

+.SH DESCRIPTION
+.PP
+This command causes the current evaluation to be unwound with an error. The

+.PP
+The stack will be unwound until the error is trapped by a suitable \fBcatch\fR
+or \fBtry\fR command. If it reaches the event loop without being trapped, it
+will be reported through the \fBbgerror\fR mechanism. If it reaches the top
+level of script evaluation in \fBtclsh\fR, it will be printed on the console
+before, in the non-interactive case, causing an exit (the behavior in other

+\fB::tcl::tm::path add \fR?\fIpath\fR...?

+.BE
+.SH DESCRIPTION
+.PP
+This document describes the facilities for locating and loading Tcl
+Modules (see \fBMODULE DEFINITION\fR for the definition of a Tcl Module).
+The following commands are supported:
+.TP
+\fB::tcl::tm::path add \fR?\fIpath\fR...?
+.
+The paths are added at the head to the list of module paths, in order
+of appearance. This means that the last argument ends up as the new
+head of the list.
+.RS
+.PP
+The command enforces the restriction that no path may be an ancestor
+directory of any other path on the list. If any of the new paths
+violates this restriction an error will be raised, before any of the
+paths have been added. In other words, if only one path argument
+violates the restriction then none will be added.
+.PP
+If a path is already present as is, no error will be raised and no
+action will be taken.
+.PP
+Paths are searched later in the order of their appearance in the
+list. As they are added to the front of the list they are searched in
+reverse order of addition. In other words, the paths added last are
+looked at first.
+.RE
+.TP
+\fB::tcl::tm::path remove \fR?\fIpath\fR...?
+.
+Removes the paths from the list of module paths. The command silently
+ignores all paths which are not on the list.
+.TP
+\fB::tcl::tm::path list\fR
+.
+Returns a list containing all registered module paths, in the order
+that they are searched for modules.
+.TP
+\fB::tcl::tm::roots \fR?\fIpath\fR...?
+.
+Similar to \fBpath add\fR, and layered on top of it. This command
+takes a list of paths, extends each with
+.QW "\fBtcl\fIX\fB/site-tcl\fR" ,
+and
+.QW "\fBtcl\fIX\fB/\fIX\fB.\fIy\fR" ,
+for major version \fIX\fR of the
+Tcl interpreter and minor version \fIy\fR less than or equal to the
+minor version of the interpreter, and adds the resulting set of paths
+to the list of paths to search.
+.RS
+.PP
+This command is used internally by the system to set up the
+system-specific default paths.
+.PP
+The command has been exposed to allow a build system to define
+additional root paths beyond those described by this document.
+.RE
+.SH "MODULE DEFINITION"
+.PP
+A Tcl Module is a Tcl Package contained in a single file, and no other
+files required by it. This file has to be \fBsource\fRable. In other
+words, a Tcl Module is always imported via:
+.PP
+.CS
+source module_file
+.CE
+.PP
+The \fBload\fR command is not directly used. This restriction is not
+an actual limitation, as some may believe.
+Ever since 8.4 the Tcl \fBsource\fR command reads only until the first
+^Z character. This allows us to combine an arbitrary Tcl script with
+arbitrary binary data into one file, where the script processes the
+attached data in any it chooses to fully import and activate the
+package.
+.PP
+The name of a module file has to match the regular expression:
+.PP
+.CS
+([_[:alpha:]][:_[:alnum:]]*)-([[:digit:]].*)\e.tm
+.CE
+.PP
+The first capturing parentheses provides the name of the package, the
+second clause its version. In addition to matching the pattern, the
+extracted version number must not raise an error when used in the
+command:
+.PP
+.CS
+package vcompare $version 0
+.CE
+.SH "FINDING MODULES"
+.PP
+The directory tree for storing Tcl modules is separate from other
+parts of the filesystem and independent of \fBauto_path\fR.
+.PP
+Tcl Modules are searched for in all directories listed in the result
+of the command \fB::tcl::tm::path list\fR.
+This is called the \fIModule path\fR. Neither the \fBauto_path\fR nor
+the \fBtcl_pkgPath\fR variables are used.
+All directories on the module path have to obey one restriction:
+.RS
+.PP
+For any two directories, neither is an ancestor directory of the
+other.
+.RE
+.PP
+This is required to avoid ambiguities in package naming. If for
+example the two directories
+.QW "\fIfoo/\fR"
+and
+.QW "\fIfoo/cool\fR"
+were on
+the path a package named \fBcool::ice\fR could be found via the
+names \fBcool::ice\fR or \fBice\fR, the latter potentially
+obscuring a package named \fBice\fR, unqualified.
+.PP
+Before the search is started, the name of the requested package is
+translated into a partial path, using the following algorithm:
+.RS
+.PP
+All occurrences of
+.QW "\fB::\fR"
+in the package name are replaced by
+the appropriate directory separator character for the platform we are
+on. On Unix, for example, this is
+.QW "\fB/\fR" .
+.RE
+.PP
+Example:
+.RS
+.PP
+The requested package is \fBencoding::base64\fR. The generated
+partial path is
+.QW "\fIencoding/base64\fR" .
+.RE
+.PP
+After this translation the package is looked for in all module paths,
+by combining them one-by-one, first to last with the partial path to
+form a complete search pattern. Note that the search algorithm rejects
+all files where the filename does not match the regular expression
+given in the section \fBMODULE DEFINITION\fR. For the remaining
+files \fIprovide scripts\fR are generated and added to the package
+ifneeded database.
+.PP
+The algorithm falls back to the previous unknown handler when none of
+the found module files satisfy the request. If the request was
+satisfied the fall-back is ignored.
+.PP
+Note that packages in module form have \fIno\fR control over the
+\fIindex\fR and \fIprovide script\fRs entered into the package
+database for them.
+For a module file \fBMF\fR the \fIindex script\fR is always:
+.PP
+.CS
+package ifneeded \fBPNAME PVERSION\fR [list source \fBMF\fR]
+.CE
+.PP
+and the \fIprovide script\fR embedded in the above is:
+.PP
+.CS
+source \fBMF\fR
+.CE
+.PP
+Both package name \fBPNAME\fR and package version \fBPVERSION\fR are
+extracted from the filename \fBMF\fR according to the definition
+below:
+.PP
+.CS
+\fBMF\fR = /module_path/\fBPNAME\(fm\fR-\fBPVERSION\fR.tm
+.CE
+.PP
+Where \fBPNAME\(fm\fR is the partial path of the module as defined in
+section \fBFINDING MODULES\fR, and translated into \fBPNAME\fR by
+changing all directory separators to
+.QW "\fB::\fR" ,
+and \fBmodule_path\fR is the path (from the list of paths to search)
+that we found the module file under.
+.PP
+Note also that we are here creating a connection between package names
+and paths. Tcl is case-sensitive when it comes to comparing package
+names, but there are filesystems which are not, like NTFS. Luckily
+these filesystems do store the case of the name, despite not using the
+information when comparing.
+.PP
+Given the above we allow the names for packages in Tcl modules to have
+mixed-case, but also require that there are no collisions when
+comparing names in a case-insensitive manner. In other words, if a
+package \fBFoo\fR is deployed in the form of a Tcl Module,
+packages like \fBfoo\fR, \fBfOo\fR, etc. are not allowed
+anymore.
+.SH "DEFAULT PATHS"
+.PP
+The default list of paths on the module path is computed by a
+\fBtclsh\fR as follows, where \fIX\fR is the major version of the Tcl
+interpreter and \fIy\fR is less than or equal to the minor version of
+the Tcl interpreter.
+.PP
+All the default paths are added to the module path, even those paths
+which do not exist. Non-existent paths are filtered out during actual
+searches. This enables a user to create one of the paths searched when
+needed and all running applications will automatically pick up any
+modules placed in them.
+.PP
+The paths are added in the order as they are listed below, and for
+lists of paths defined by an environment variable in the order they
+are found in the variable.
+.SS "SYSTEM SPECIFIC PATHS"
+.TP
+\fBfile normalize [info library]/../tcl\fIX\fB/\fIX\fB.\fIy\fR
+.
+In other words, the interpreter will look into a directory specified
+by its major version and whose minor versions are less than or equal
+to the minor version of the interpreter.
+.RS
+.PP
+For example for Tcl 8.4 the paths searched are:
+.PP
+.CS
+\fB[info library]/../tcl8/8.4\fR
+\fB[info library]/../tcl8/8.3\fR
+\fB[info library]/../tcl8/8.2\fR
+\fB[info library]/../tcl8/8.1\fR
+\fB[info library]/../tcl8/8.0\fR
+.CE
+.PP
+This definition assumes that a package defined for Tcl \fIX\fB.\fIy\fR
+can also be used by all interpreters which have the same major number
+\fIX\fR and a minor number greater than \fIy\fR.
+.RE
+.TP
+\fBfile normalize EXEC/tcl\fIX\fB/\fIX\fB.\fIy\fR
+.
+Where \fBEXEC\fR is \fBfile normalize [info nameofexecutable]/../lib\fR
+or \fBfile normalize [::tcl::pkgconfig get libdir,runtime]\fR
+.RS
+.PP
+This sets of paths is handled equivalently to the set coming before,
+except that it is anchored in \fBEXEC_PREFIX\fR.
+For a build with \fBPREFIX\fR = \fBEXEC_PREFIX\fR the two sets are
+identical.
+.RE
+.SS "SITE SPECIFIC PATHS"
+.TP
+\fBfile normalize [info library]/../tcl\fIX\fB/site-tcl\fR
+.
+Note that this is always a single entry because \fIX\fR is always a
+specific value (the current major version of Tcl).
+.SS "USER SPECIFIC PATHS"
+.TP
+\fB$::env(TCL\fIX\fB_\fIy\fB_TM_PATH)\fR
+.
+A list of paths, separated by either \fB:\fR (Unix) or \fB;\fR
+(Windows). This is user and site specific as this environment variable
+can be set not only by the user's profile, but by system configuration
+scripts as well.
+.TP
+\fB$::env(TCL\fIX\fB.\fIy\fB_TM_PATH)\fR
+.
+Same meaning and content as the previous variable. However the use of
+dot '.' to separate major and minor version number makes this name
+less to non-portable and its use is discouraged. Support of this
+variable has been kept only for backward compatibility with the
+original specification, i.e. TIP 189.
+.PP
+These paths are seen and therefore shared by all Tcl shells in the
+\fB$::env(PATH)\fR of the user.
+.PP
+Note that \fIX\fR and \fIy\fR follow the general rules set out
+above. In other words, Tcl 8.4, for example, will look at these 10
+environment variables:
+.PP
+.CS
+\fB$::env(TCL8.4_TM_PATH)\fR  \fB$::env(TCL8_4_TM_PATH)\fR
+\fB$::env(TCL8.3_TM_PATH)\fR  \fB$::env(TCL8_3_TM_PATH)\fR
+\fB$::env(TCL8.2_TM_PATH)\fR  \fB$::env(TCL8_2_TM_PATH)\fR

+.SH SYNOPSIS
+\fBtrace \fIoption\fR ?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command causes Tcl commands to be executed whenever certain operations are
+invoked.  The legal \fIoption\fRs (which may be abbreviated) are:
+.TP
+\fBtrace add \fItype name ops ?args?\fR
+Where \fItype\fR is \fBcommand\fR, \fBexecution\fR, or \fBvariable\fR.
+.RS
+.TP
+\fBtrace add command\fR \fIname ops commandPrefix\fR
+.
+Arrange for \fIcommandPrefix\fR to be executed (with additional arguments)
+whenever command \fIname\fR is modified in one of the ways given by the list
+\fIops\fR. \fIName\fR will be resolved using the usual namespace resolution
+rules used by commands. If the command does not exist, an error will be
+thrown.
+.RS
+.PP
+\fIOps\fR indicates which operations are of interest, and is a list of
+one or more of the following items:
+.TP
+\fBrename\fR
+.
+Invoke \fIcommandPrefix\fR whenever the traced command is renamed.  Note that
+renaming to the empty string is considered deletion, and will not be traced
+with
+.QW \fBrename\fR .
+.TP
+\fBdelete\fR
+.
+Invoke \fIcommandPrefix\fR when the traced command is deleted. Commands can be
+deleted explicitly by using the \fBrename\fR command to rename the command to
+an empty string. Commands are also deleted when the interpreter is deleted,
+but traces will not be invoked because there is no interpreter in which to
+execute them.
+.PP
+When the trace triggers, depending on the operations being traced, a number of
+arguments are appended to \fIcommandPrefix\fR so that the actual command is as
+follows:
+.PP
+.CS
+\fIcommandPrefix oldName newName op\fR
+.CE
+.PP
+\fIOldName\fR and \fInewName\fR give the traced command's current (old) name,
+and the name to which it is being renamed (the empty string if this is a
+.QW delete
+operation).
+\fIOp\fR indicates what operation is being performed on the
+command, and is one of \fBrename\fR or \fBdelete\fR as
+defined above.  The trace operation cannot be used to stop a command
+from being deleted.  Tcl will always remove the command once the trace
+is complete.  Recursive renaming or deleting will not cause further traces
+of the same type to be evaluated, so a delete trace which itself
+deletes the command, or a rename trace which itself renames the
+command will not cause further trace evaluations to occur.
+Both \fIoldName\fR and \fInewName\fR are fully qualified with any namespace(s)
+in which they appear.
+.RE
+.TP
+\fBtrace add execution\fR \fIname ops commandPrefix\fR
+.
+Arrange for \fIcommandPrefix\fR to be executed (with additional arguments)
+whenever command \fIname\fR is executed, with traces occurring at the points
+indicated by the list \fIops\fR.  \fIName\fR will be resolved using the usual
+namespace resolution rules used by commands.  If the command does not exist,
+an error will be thrown.
+.RS
+.PP
+\fIOps\fR indicates which operations are of interest, and is a list of
+one or more of the following items:
+.TP
+\fBenter\fR
+Invoke \fIcommandPrefix\fR whenever the command \fIname\fR is executed,
+just before the actual execution takes place.
+.TP
+\fBleave\fR
+Invoke \fIcommandPrefix\fR whenever the command \fIname\fR is executed,
+just after the actual execution takes place.
+.TP
+\fBenterstep\fR
+.
+Invoke \fIcommandPrefix\fR for every Tcl command which is executed from the
+start of the execution of the procedure \fIname\fR until that
+procedure finishes. \fICommandPrefix\fR is invoked just before the actual
+execution of the Tcl command being reported takes place.  For example
+if we have
+.QW "proc foo {} { puts \N'34'hello\N'34' }" ,
+then an \fIenterstep\fR trace would be invoked just before
+.QW "\fIputs \N'34'hello\N'34'\fR"
+is executed.
+Setting an \fIenterstep\fR trace on a command \fIname\fR that does not refer
+to a procedure will not result in an error and is simply ignored.
+.TP
+\fBleavestep\fR
+.
+Invoke \fIcommandPrefix\fR for every Tcl command which is executed from the
+start of the execution of the procedure \fIname\fR until that
+procedure finishes. \fICommandPrefix\fR is invoked just after the actual
+execution of the Tcl command being reported takes place.
+Setting a \fIleavestep\fR trace on a command \fIname\fR that does not refer to
+a procedure will not result in an error and is simply ignored.
+.PP
+When the trace triggers, depending on the operations being traced, a
+number of arguments are appended to \fIcommandPrefix\fR so that the actual
+command is as follows:
+.PP
+For \fBenter\fR and \fBenterstep\fR operations:
+.PP
+.CS
+\fIcommandPrefix command-string op\fR
+.CE
+.PP
+\fICommand-string\fR gives the complete current command being
+executed (the traced command for a \fBenter\fR operation, an
+arbitrary command for a \fBenterstep\fR operation), including
+all arguments in their fully expanded form.
+\fIOp\fR indicates what operation is being performed on the
+command execution, and is one of \fBenter\fR or \fBenterstep\fR as
+defined above.  The trace operation can be used to stop the
+command from executing, by deleting the command in question.  Of
+course when the command is subsequently executed, an
+.QW "invalid command"
+error will occur.
+.PP
+For \fBleave\fR and \fBleavestep\fR operations:
+.PP
+.CS
+\fIcommandPrefix command-string code result op\fR
+.CE
+.PP
+\fICommand-string\fR gives the complete current command being
+executed (the traced command for a \fBenter\fR operation, an
+arbitrary command for a \fBenterstep\fR operation), including
+all arguments in their fully expanded form.
+\fICode\fR gives the result code of that execution, and \fIresult\fR
+the result string.
+\fIOp\fR indicates what operation is being performed on the
+command execution, and is one of \fBleave\fR or \fBleavestep\fR as
+defined above.
+Note that the creation of many \fBenterstep\fR or
+\fBleavestep\fR traces can lead to unintuitive results, since the
+invoked commands from one trace can themselves lead to further
+command invocations for other traces.
+.PP
+\fICommandPrefix\fR executes in the same context as the code that invoked
+the traced operation: thus the \fIcommandPrefix\fR, if invoked from a
+procedure, will have access to the same local variables as code in the
+procedure. This context may be different than the context in which the trace
+was created. If \fIcommandPrefix\fR invokes a procedure (which it normally
+does) then the procedure will have to use \fBupvar\fR or \fBuplevel\fR
+commands if it wishes to access the local variables of the code which invoked
+the trace operation.
+.PP
+While \fIcommandPrefix\fR is executing during an execution trace, traces
+on \fIname\fR are temporarily disabled. This allows the \fIcommandPrefix\fR
+to execute \fIname\fR in its body without invoking any other traces again.
+If an error occurs while executing the \fIcommandPrefix\fR, then the
+command \fIname\fR as a whole will return that same error.
+.PP
+When multiple traces are set on \fIname\fR, then for \fIenter\fR
+and \fIenterstep\fR operations, the traced commands are invoked
+in the reverse order of how the traces were originally created;
+and for \fIleave\fR and \fIleavestep\fR operations, the traced
+commands are invoked in the original order of creation.
+.PP
+The behavior of execution traces is currently undefined for a command
+\fIname\fR imported into another namespace.
+.RE
+.TP
+\fBtrace add variable\fI name ops commandPrefix\fR
+Arrange for \fIcommandPrefix\fR to be executed whenever variable \fIname\fR
+is accessed in one of the ways given by the list \fIops\fR.  \fIName\fR may
+refer to a normal variable, an element of an array, or to an array
+as a whole (i.e. \fIname\fR may be just the name of an array, with no
+parenthesized index).  If \fIname\fR refers to a whole array, then
+\fIcommandPrefix\fR is invoked whenever any element of the array is
+manipulated.  If the variable does not exist, it will be created but
+will not be given a value, so it will be visible to \fBnamespace which\fR
+queries, but not to \fBinfo exists\fR queries.
+.RS
+.PP
+\fIOps\fR indicates which operations are of interest, and is a list of
+one or more of the following items:
+.TP
+\fBarray\fR
+Invoke \fIcommandPrefix\fR whenever the variable is accessed or modified via
+the \fBarray\fR command, provided that \fIname\fR is not a scalar
+variable at the time that the \fBarray\fR command is invoked.  If
+\fIname\fR is a scalar variable, the access via the \fBarray\fR
+command will not trigger the trace.
+.TP
+\fBread\fR
+Invoke \fIcommandPrefix\fR whenever the variable is read.
+.TP
+\fBwrite\fR
+Invoke \fIcommandPrefix\fR whenever the variable is written.
+.TP
+\fBunset\fR
+Invoke \fIcommandPrefix\fR whenever the variable is unset.  Variables
+can be unset explicitly with the \fBunset\fR command, or
+implicitly when procedures return (all of their local variables
+are unset).  Variables are also unset when interpreters are
+deleted, but traces will not be invoked because there is no
+interpreter in which to execute them.
+.PP
+When the trace triggers, three arguments are appended to
+\fIcommandPrefix\fR so that the actual command is as follows:
+.PP
+.CS
+\fIcommandPrefix name1 name2 op\fR
+.CE
+.PP
+\fIName1\fR and \fIname2\fR give the name(s) for the variable
+being accessed:  if the variable is a scalar then \fIname1\fR
+gives the variable's name and \fIname2\fR is an empty string;
+if the variable is an array element then \fIname1\fR gives the
+name of the array and name2 gives the index into the array;
+if an entire array is being deleted and the trace was registered
+on the overall array, rather than a single element, then \fIname1\fR
+gives the array name and \fIname2\fR is an empty string.
+\fIName1\fR and \fIname2\fR are not necessarily the same as the
+name used in the \fBtrace variable\fR command:  the \fBupvar\fR
+command allows a procedure to reference a variable under a
+different name.
+\fIOp\fR indicates what operation is being performed on the
+variable, and is one of \fBread\fR, \fBwrite\fR, or \fBunset\fR as
+defined above.
+.PP
+\fICommandPrefix\fR executes in the same context as the code that invoked
+the traced operation:  if the variable was accessed as part of a Tcl
+procedure, then \fIcommandPrefix\fR will have access to the same local
+variables as code in the procedure.  This context may be different
+than the context in which the trace was created. If \fIcommandPrefix\fR
+invokes a procedure (which it normally does) then the procedure will
+have to use \fBupvar\fR or \fBuplevel\fR if it wishes to access the
+traced variable.  Note also that \fIname1\fR may not necessarily be
+the same as the name used to set the trace on the variable;
+differences can occur if the access is made through a variable defined
+with the \fBupvar\fR command.
+.PP
+For read and write traces, \fIcommandPrefix\fR can modify the variable to
+affect the result of the traced operation.  If \fIcommandPrefix\fR modifies
+the value of a variable during a read or write trace, then the new
+value will be returned as the result of the traced operation.  The
+return value from  \fIcommandPrefix\fR is ignored except that if it returns
+an error of any sort then the traced operation also returns an error
+with the same error message returned by the trace command (this
+mechanism can be used to implement read-only variables, for example).
+For write traces, \fIcommandPrefix\fR is invoked after the variable's value
+has been changed; it can write a new value into the variable to
+override the original value specified in the write operation.  To
+implement read-only variables, \fIcommandPrefix\fR will have to restore the
+old value of the variable.
+.PP
+While \fIcommandPrefix\fR is executing during a read or write trace, traces
+on the variable are temporarily disabled.  This means that reads and
+writes invoked by \fIcommandPrefix\fR will occur directly, without invoking
+\fIcommandPrefix\fR (or any other traces) again.  However, if
+\fIcommandPrefix\fR unsets the variable then unset traces will be invoked.
+.PP
+When an unset trace is invoked, the variable has already been deleted:
+it will appear to be undefined with no traces.  If an unset occurs
+because of a procedure return, then the trace will be invoked in the
+variable context of the procedure being returned to:  the stack frame
+of the returning procedure will no longer exist.  Traces are not
+disabled during unset traces, so if an unset trace command creates a
+new trace and accesses the variable, the trace will be invoked.  Any
+errors in unset traces are ignored.
+.PP
+If there are multiple traces on a variable they are invoked in order
+of creation, most-recent first.  If one trace returns an error, then
+no further traces are invoked for the variable.  If an array element
+has a trace set, and there is also a trace set on the array as a
+whole, the trace on the overall array is invoked before the one on the
+element.
+.PP
+Once created, the trace remains in effect either until the trace is
+removed with the \fBtrace remove variable\fR command described below,
+until the variable is unset, or until the interpreter is deleted.
+Unsetting an element of array will remove any traces on that element,
+but will not remove traces on the overall array.
+.PP
+This command returns an empty string.

+.SH NAME
+transchan \- command handler API of channel transforms
+.SH SYNOPSIS
+\fBcmdPrefix \fIoption\fR ?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+The Tcl-level handler for a channel transformation has to be a command with
+subcommands (termed an \fIensemble\fR despite not implying that it must be
+created with \fBnamespace ensemble create\fR; this mechanism is not tied to
+\fBnamespace ensemble\fR in any way). Note that \fIcmdPrefix\fR is whatever
+was specified in the call to \fBchan push\fR, and may consist of multiple
+arguments; this will be expanded to multiple words in place of the prefix.
+.PP
+Of all the possible subcommands, the handler \fImust\fR support
+\fBinitialize\fR and \fBfinalize\fR. Transformations for writable channels
+must also support \fBwrite\fR, and transformations for readable channels must
+also support \fBread\fR.
+.PP
+Note that in the descriptions below \fIcmdPrefix\fR may be more than one word,
+and \fIhandle\fR is the value returned by the \fBchan push\fR call used to
+create the transformation.
+.SS "GENERIC SUBCOMMANDS"
+.PP
+The following subcommands are relevant to all types of channel.
+.TP
+\fIcmdPrefix \fBclear \fIhandle\fR
+.
+This optional subcommand is called to signify to the transformation that any
+data stored in internal buffers (either incoming or outgoing) must be
+cleared. It is called when a \fBchan seek\fR is performed on the channel being
+transformed.
+.TP
+\fIcmdPrefix \fBfinalize \fIhandle\fR
+.
+This mandatory subcommand is called last for the given \fIhandle\fR, and then
+never again, and it exists to allow for cleaning up any Tcl-level data
+structures associated with the transformation. \fIWarning!\fR Any errors
+thrown by this subcommand will be ignored. It is not guaranteed to be called
+if the interpreter is deleted.
+.TP
+\fIcmdPrefix \fBinitialize \fIhandle mode\fR
+.
+This mandatory subcommand is called first, and then never again (for the given
+\fIhandle\fR). Its responsibility is to initialize all parts of the
+transformation at the Tcl level. The \fImode\fR is a list containing any of
+\fBread \fRand \fBwrite\fR.
+.RS
+.TP
+\fBwrite\fR
+.
+implies that the channel is writable.
+.TP
+\fBread\fR
+.
+implies that the channel is readable.
+.PP
+The return value of the subcommand should be a list containing the names of
+all subcommands supported by this handler. Any error thrown by the subcommand
+will prevent the creation of the transformation. The thrown error will appear
+as error thrown by \fBchan push\fR.
+.RE
+.SS "READ-RELATED SUBCOMMANDS"
+.PP
+These subcommands are used for handling transformations applied to readable
+channels; though strictly \fBread \fRis optional, it must be supported if any
+of the others is or the channel will be made non-readable.
+.TP
+\fIcmdPrefix \fBdrain \fIhandle\fR
+.
+This optional subcommand is called whenever data in the transformation input
+(i.e. read) buffer has to be forced upward, i.e. towards the user or script.
+The result returned by the method is taken as the \fIbinary\fR data to push
+upward to the level above this transformation (the reader or a higher-level
+transformation).
+.RS
+.PP
+In other words, when this method is called the transformation cannot defer the
+actual transformation operation anymore and has to transform all data waiting
+in its internal read buffers and return the result of that action.
+.RE
+.TP
+\fIcmdPrefix \fBlimit? \fIhandle\fR
+.
+This optional subcommand is called to allow the Tcl I/O engine to determine
+how far ahead it should read. If present, it should return an integer number
+greater than zero which indicates how many bytes ahead should be read, or an
+integer less than zero to indicate that the I/O engine may read as far ahead
+as it likes.
+.TP
+\fIcmdPrefix \fBread \fIhandle buffer\fR
+.
+This subcommand, which must be present if the transformation is to work with
+readable channels, is called whenever the base channel, or a transformation
+below this transformation, pushes data upward. The \fIbuffer\fR contains the
+binary data which has been given to us from below. It is the responsibility of
+this subcommand to actually transform the data. The result returned by the
+subcommand is taken as the binary data to push further upward to the
+transformation above this transformation. This can also be the user or script
+that originally read from the channel.
+.RS
+.PP
+Note that the result is allowed to be empty, or even less than the data we
+received; the transformation is not required to transform everything given to
+it right now. It is allowed to store incoming data in internal buffers and to
+defer the actual transformation until it has more data.
+.RE
+.SS "WRITE-RELATED SUBCOMMANDS"
+.PP
+These subcommands are used for handling transformations applied to writable
+channels; though strictly \fBwrite\fR is optional, it must be supported if any
+of the others is or the channel will be made non-writable.
+.TP
+\fIcmdPrefix \fBflush \fIhandle\fR
+.
+This optional subcommand is called whenever data in the transformation 'write'
+buffer has to be forced downward, i.e. towards the base channel. The result
+returned by the subcommand is taken as the binary data to write to the
+transformation below the current transformation. This can be the base channel
+as well.
+.RS
+.PP
+In other words, when this subcommand is called the transformation cannot defer
+the actual transformation operation anymore and has to transform all data
+waiting in its internal write buffers and return the result of that action.
+.RE
+.TP
+\fIcmdPrefix \fBwrite \fIhandle buffer\fR
+.
+This subcommand, which must be present if the transformation is to work with
+writable channels, is called whenever the user, or a transformation above this
+transformation, writes data downward. The \fIbuffer\fR contains the binary
+data which has been written to us. It is the responsibility of this subcommand
+to actually transform the data.
+.RS
+.PP
+The result returned by the subcommand is taken as the binary data to write to
+the transformation below this transformation. This can be the base channel as
+well. Note that the result is allowed to be empty, or less than the data we
+got; the transformation is not required to transform everything which was
+written to it right now. It is allowed to store this data in internal buffers
+and to defer the actual transformation until it has more data.

+try \- Trap and process errors and exceptions
+.SH SYNOPSIS
+\fBtry\fI body\fR ?\fIhandler...\fR? ?\fBfinally\fI script\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command executes the script \fIbody\fR and, depending on what the outcome
+of that script is (normal exit, error, or some other exceptional result), runs
+a handler script to deal with the case. Once that has all happened, if the
+\fBfinally\fR clause is present, the \fIscript\fR it includes will be run and
+the result of the handler (or the \fIbody\fR if no handler matched) is allowed
+to continue to propagate. Note that the \fBfinally\fR clause is processed even
+if an error occurs and irrespective of which, if any, \fIhandler\fR is used.
+.PP
+The \fIhandler\fR clauses are each expressed as several words, and must have
+one of the following forms:
+.TP
+\fBon \fIcode variableList script\fR
+.
+This clause matches if the evaluation of \fIbody\fR completed with the
+exception code \fIcode\fR. The \fIcode\fR may be expressed as an integer or
+one of the following literal words: \fBok\fR, \fBerror\fR, \fBreturn\fR,
+\fBbreak\fR, or \fBcontinue\fR. Those literals correspond to the integers 0
+through 4 respectively.
+.TP
+\fBtrap \fIpattern variableList script\fR
+.
+This clause matches if the evaluation of \fIbody\fR resulted in an error and
+the prefix of the \fB\-errorcode\fR from the interpreter's status dictionary
+is equal to the \fIpattern\fR. The number of prefix words taken from the
+\fB\-errorcode\fR is equal to the list-length of \fIpattern\fR, and inter-word
+spaces are normalized in both the \fB\-errorcode\fR and \fIpattern\fR before
+comparison.
+.PP
+The \fIvariableList\fR word in each \fIhandler\fR is always interpreted as a
+list of variable names. If the first word of the list is present and
+non-empty, it names a variable into which the result of the evaluation of
+\fIbody\fR (from the main \fBtry\fR) will be placed; this will contain the
+human-readable form of any errors. If the second word of the list is present
+and non-empty, it names a variable into which the options dictionary of the
+interpreter at the moment of completion of execution of \fIbody\fR
+will be placed.
+.PP
+The \fIscript\fR word of each \fIhandler\fR is also always interpreted the
+same: as a Tcl script to evaluate if the clause is matched. If \fIscript\fR is
+a literal
+.QW \-
+and the \fIhandler\fR is not the last one, the \fIscript\fR of the following
+\fIhandler\fR is invoked instead (just like with the \fBswitch\fR command).
+.PP
+Note that \fIhandler\fR clauses are matched against in order, and that the
+first matching one is always selected. At most one \fIhandler\fR clause will
+selected. As a consequence, an \fBon error\fR will mask any subsequent
+\fBtrap\fR in the \fBtry\fR. Also note that \fBon error\fR is equivalent to
+\fBtrap {}\fR.
+.PP
+If an exception (i.e. any non-\fBok\fR result) occurs during the evaluation of
+either the \fIhandler\fR or the \fBfinally\fR clause, the original exception's
+status dictionary will be added to the new exception's status dictionary under
+the \fB\-during\fR key.

+.SH NAME
+unknown \- Handle attempts to use non-existent commands
+.SH SYNOPSIS
+\fBunknown \fIcmdName \fR?\fIarg arg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command is invoked by the Tcl interpreter whenever a script
+tries to invoke a command that does not exist.  The default implementation
+of \fBunknown\fR is a library procedure defined when Tcl initializes an
+interpreter.  You can override the default \fBunknown\fR to change its
+functionality, or you can register a new handler for individual namespaces
+using the \fBnamespace unknown\fR command.  Note that there is no default 
+implementation of \fBunknown\fR in a safe interpreter.
+.PP
+If the Tcl interpreter encounters a command name for which there
+is not a defined command (in either the current namespace, or the 
+global namespace), then Tcl checks for the existence of
+an unknown handler for the current namespace. By default, this
+handler is a command named \fB::unknown\fR.  If there is no such 
+command, then the interpreter returns an error.
+If the \fBunknown\fR command exists (or a new handler has been
+registered for the current namespace), then it is invoked with
+arguments consisting of the fully-substituted name and arguments
+for the original non-existent command.
+The \fBunknown\fR command typically does things like searching
+through library directories for a command procedure with the name
+\fIcmdName\fR, or expanding abbreviated command names to full-length,
+or automatically executing unknown commands as sub-processes.
+In some cases (such as expanding abbreviations) \fBunknown\fR will
+change the original command slightly and then (re-)execute it.
+The result of the \fBunknown\fR command is used as the result for
+the original non-existent command.
+.PP
+The default implementation of \fBunknown\fR behaves as follows.
+It first calls the \fBauto_load\fR library procedure to load the command.
+If this succeeds, then it executes the original command with its
+original arguments.
+If the auto-load fails then \fBunknown\fR calls \fBauto_execok\fR
+to see if there is an executable file by the name \fIcmd\fR.
+If so, it invokes the Tcl \fBexec\fR command
+with \fIcmd\fR and all the \fIargs\fR as arguments.
+If \fIcmd\fR cannot be auto-executed, \fBunknown\fR checks to
+see if the command was invoked at top-level and outside of any
+script.  If so, then \fBunknown\fR takes two additional steps.
+First, it sees if \fIcmd\fR has one of the following three forms:
+\fB!!\fR, \fB!\fIevent\fR, or \fB^\fIold\fB^\fInew\fR?\fB^\fR?.
+If so, then \fBunknown\fR carries out history substitution
+in the same way that \fBcsh\fR would for these constructs.
+Finally, \fBunknown\fR checks to see if \fIcmd\fR is
+a unique abbreviation for an existing Tcl command.
+If so, it expands the command name and executes the command with
+the original arguments.
+If none of the above efforts has been able to execute
+the command, \fBunknown\fR generates an error return.
+If the global variable \fBauto_noload\fR is defined, then the auto-load
+step is skipped.
+If the global variable \fBauto_noexec\fR is defined then the
+auto-exec step is skipped.
+Under normal circumstances the return value from \fBunknown\fR
+is the return value from the command that was eventually
+executed.
+.SH EXAMPLE
+Arrange for the \fBunknown\fR command to have its standard behavior
+except for first logging the fact that a command was not found:

+# Save the original one so we can chain to it

+.SH SYNOPSIS
+\fBunload \fR?\fIswitches\fR? \fIfileName\fR
+.br
+\fBunload \fR?\fIswitches\fR? \fIfileName packageName\fR
+.br
+\fBunload \fR?\fIswitches\fR? \fIfileName packageName interp\fR
+.BE
+.SH DESCRIPTION
+.PP
+This command tries to unload shared libraries previously loaded
+with \fBload\fR from the application's address space.  \fIfileName\fR
+is the name of the file containing the library file to be unload;  it
+must be the same as the filename provided to \fBload\fR for
+loading the library.
+The \fIpackageName\fR argument is the name of the package (as
+determined by or passed to \fBload\fR), and is used to
+compute the name of the unload procedure; if not supplied, it is
+computed from \fIfileName\fR in the same manner as \fBload\fR.
+The \fIinterp\fR argument is the path name of the interpreter from
+which to unload the package (see the \fBinterp\fR manual entry for
+details); if \fIinterp\fR is omitted, it defaults to the
+interpreter in which the \fBunload\fR command was invoked.
+.PP
+If the initial arguments to \fBunload\fR start with \fB\-\fR then
+they are treated as switches.  The following switches are
+currently supported:
+.TP
+\fB\-nocomplain\fR
+.
+Suppresses all error messages. If this switch is given, \fBunload\fR will
+never report an error.
+.TP
+\fB\-keeplibrary\fR
+.
+This switch will prevent \fBunload\fR from issuing the operating system call
+that will unload the library from the process. 
+.TP
+\fB\-\|\-\fR
+.
+Marks the end of switches.  The argument following this one will
+be treated as a \fIfileName\fR even if it starts with a \fB\-\fR.
+.SS "UNLOAD OPERATION"
+.PP
+When a file containing a shared library is loaded through the
+\fBload\fR command, Tcl associates two reference counts to the library
+file. The first counter shows how many times the library has been
+loaded into normal (trusted) interpreters while the second describes how many
+times the library has been loaded into safe interpreters. As a file containing
+a shared library can be loaded only once by Tcl (with the first \fBload\fR
+call on the file), these counters track how many interpreters use the library.
+Each subsequent call to \fBload\fR after the first simply increments the
+proper reference count.
+.PP
+\fBunload\fR works in the opposite direction. As a first step, \fBunload\fR
+will check whether the library is unloadable: an unloadable library exports
+a special unload procedure. The name of the unload procedure is determined by
+\fIpackageName\fR and whether or not the target interpreter
+is a safe one.  For normal interpreters the name of the initialization
+procedure will have the form \fIpkg\fB_Unload\fR, where \fIpkg\fR
+is the same as \fIpackageName\fR except that the first letter is
+converted to upper case and all other letters
+are converted to lower case.  For example, if \fIpackageName\fR is
+\fBfoo\fR or \fBFOo\fR, the initialization procedure's name will
+be \fBFoo_Unload\fR.
+If the target interpreter is a safe interpreter, then the name
+of the initialization procedure will be \fIpkg\fB_SafeUnload\fR
+instead of \fIpkg\fB_Unload\fR.
+.PP
+If \fBunload\fR determines that a library is not unloadable (or unload
+functionality has been disabled during compilation), an error will be returned.
+If the library is unloadable, then \fBunload\fR will call the unload
+procedure. If the unload procedure returns \fBTCL_OK\fR, \fBunload\fR will proceed
+and decrease the proper reference count (depending on the target interpreter
+type). When both reference counts have reached 0, the library will be
+detached from the process.
+.SS "UNLOAD HOOK PROTOTYPE"
+.PP
+The unload procedure must match the following prototype:
+.PP
+.CS
+typedef int \fBTcl_PackageUnloadProc\fR(
+        Tcl_Interp *\fIinterp\fR,
+        int \fIflags\fR);
+.CE
+.PP
+The \fIinterp\fR argument identifies the interpreter from which the
+library is to be unloaded.  The unload procedure must return
+\fBTCL_OK\fR or \fBTCL_ERROR\fR to indicate whether or not it completed
+successfully;  in the event of an error it should set the interpreter's result
+to point to an error message.  In this case, the result of the
+\fBunload\fR command will be the result returned by the unload procedure.
+.PP
+The \fIflags\fR argument can be either \fBTCL_UNLOAD_DETACH_FROM_INTERPRETER\fR
+or \fBTCL_UNLOAD_DETACH_FROM_PROCESS\fR. In case the library will remain
+attached to the process after the unload procedure returns (i.e. because
+the library is used by other interpreters),
+\fBTCL_UNLOAD_DETACH_FROM_INTERPRETER\fR will be defined. However, if the
+library is used only by the target interpreter and the library will be
+detached from the application as soon as the unload procedure returns,
+the \fIflags\fR argument will be set to \fBTCL_UNLOAD_DETACH_FROM_PROCESS\fR. 
+.SS NOTES

+The \fBunload\fR command cannot unload libraries that are statically
+linked with the application.
+If \fIfileName\fR is an empty string, then the \fIpackageName\fR argument must
+be specified.
+.PP
+If \fIpackageName\fR is omitted or specified as an empty string,
+Tcl tries to guess the name of the package.
+This may be done differently on different platforms.
+The default guess, which is used on most UNIX platforms, is to
+take the last element of \fIfileName\fR, strip off the first
+three characters if they are \fBlib\fR, and use any following
+alphabetic and underline characters as the module name.
+For example, the command \fBunload libxyz4.2.so\fR uses the module
+name \fBxyz\fR and the command \fBunload bin/last.so {}\fR uses the
+module name \fBlast\fR.
+.SH "PORTABILITY ISSUES"
+.TP
+\fBUnix\fR\0\0\0\0\0
+.
+Not all unix operating systems support library unloading. Under such
+an operating system \fBunload\fR returns an error (unless \fB\-nocomplain\fR
+has been specified).
+.SH BUGS
+.PP
+If the same file is \fBload\fRed by different \fIfileName\fRs, it will
+be loaded into the process's address space multiple times.  The
+behavior of this varies from system to system (some systems may
+detect the redundant loads, others may not). In case a library has been
+silently detached by the operating system (and as a result Tcl thinks the
+library is still loaded), it may be dangerous to use
+\fBunload\fR on such a library (as the library will be completely detached
+from the application while some interpreters will continue to use it).
+.SH EXAMPLE
+.PP
+If an unloadable module in the file \fBfoobar.dll\fR had been loaded
+using the \fBload\fR command like this (on Windows):
+.PP
+.CS
+load c:/some/dir/foobar.dll
+.CE
+.PP
+then it would be unloaded like this:
+.PP
+.CS
+\fBunload\fR c:/some/dir/foobar.dll
+.CE
+.PP
+This allows a C code module to be installed temporarily into a
+long-running Tcl program and then removed again (either because it is
+no longer needed or because it is being updated with a new version)
+without having to shut down the overall Tcl process.

+.SH SYNOPSIS
+\fBunset \fR?\fB\-nocomplain\fR? ?\fB\-\-\fR? ?\fIname name name ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command removes one or more variables.
+Each \fIname\fR is a variable name, specified in any of the
+ways acceptable to the \fBset\fR command.
+If a \fIname\fR refers to an element of an array then that
+element is removed without affecting the rest of the array.
+If a \fIname\fR consists of an array name with no parenthesized
+index, then the entire array is deleted.
+The \fBunset\fR command returns an empty string as result.
+If \fB\-nocomplain\fR is specified as the first argument, any possible
+errors are suppressed.  The option may not be abbreviated, in order to
+disambiguate it from possible variable names.  The option \fB\-\-\fR
+indicates the end of the options, and should be used if you wish to
+remove a variable with the same name as any of the options.
+If an error occurs during variable deletion, any variables after the named one
+causing the error are not
+deleted.  An error can occur when the named variable does not exist, or the
+name refers to an array element but the variable is a scalar, or the name
+refers to a variable in a non-existent namespace.

+.SH SYNOPSIS
+\fBupdate\fR ?\fBidletasks\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command is used to bring the application
+.QW "up to date"
+by entering the event loop repeatedly until all pending events
+(including idle callbacks) have been processed.
+.PP
+If the \fBidletasks\fR keyword is specified as an argument to the
+command, then no new events or errors are processed;  only idle
+callbacks are invoked.
+This causes operations that are normally deferred, such as display
+updates and window layout calculations, to be performed immediately.
+.PP
+The \fBupdate idletasks\fR command is useful in scripts where
+changes have been made to the application's state and you want those
+changes to appear on the display immediately, rather than waiting
+for the script to complete.  Most display updates are performed as
+idle callbacks, so \fBupdate idletasks\fR will cause them to run.
+However, there are some kinds of updates that only happen in
+response to events, such as those triggered by window size changes;
+these updates will not occur in \fBupdate idletasks\fR.
+.PP
+The \fBupdate\fR command with no options is useful in scripts where
+you are performing a long-running computation but you still want
+the application to respond to events such as user interactions;  if
+you occasionally call \fBupdate\fR then user input will be processed
+during the next call to \fBupdate\fR.
+.SH EXAMPLE
+.PP
+Run computations for about a second and then finish:
+.PP
+.CS
+set x 1000
+set done 0
+after 1000 set done 1
+while {!$done} {
+    # A very silly example!
+    set x [expr {log($x) ** 2.8}]
+
+    # Test to see if our time-limit has been hit.  This would
+    # also give a chance for serving network sockets and, if
+    # the Tk package is loaded, updating a user interface.

+uplevel \- Execute a script in a different stack frame
+.SH SYNOPSIS
+\fBuplevel \fR?\fIlevel\fR?\fI arg \fR?\fIarg ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+All of the \fIarg\fR arguments are concatenated as if they had
+been passed to \fBconcat\fR; the result is then evaluated in the
+variable context indicated by \fIlevel\fR.  \fBUplevel\fR returns
+the result of that evaluation.
+.PP
+If \fIlevel\fR is an integer then
+it gives a distance (up the procedure calling stack) to move before
+executing the command.  If \fIlevel\fR consists of \fB#\fR followed by
+a number then the number gives an absolute level number.  If \fIlevel\fR
+is omitted then it defaults to \fB1\fR.  \fILevel\fR cannot be
+defaulted if the first \fIcommand\fR argument starts with a digit or \fB#\fR.
+.PP
+For example, suppose that procedure \fBa\fR was invoked
+from top-level, and that it called \fBb\fR, and that \fBb\fR called \fBc\fR.
+Suppose that \fBc\fR invokes the \fBuplevel\fR command.  If \fIlevel\fR
+is \fB1\fR or \fB#2\fR  or omitted, then the command will be executed
+in the variable context of \fBb\fR.  If \fIlevel\fR is \fB2\fR or \fB#1\fR
+then the command will be executed in the variable context of \fBa\fR.
+If \fIlevel\fR is \fB3\fR or \fB#0\fR then the command will be executed
+at top-level (only global variables will be visible).
+.PP
+The \fBuplevel\fR command causes the invoking procedure to disappear
+from the procedure calling stack while the command is being executed.
+In the above example, suppose \fBc\fR invokes the command
+.PP
+.CS
+\fBuplevel\fR 1 {set x 43; d}
+.CE
+.PP
+where \fBd\fR is another Tcl procedure.  The \fBset\fR command will
+modify the variable \fBx\fR in \fBb\fR's context, and \fBd\fR will execute
+at level 3, as if called from \fBb\fR.  If it in turn executes
+the command
+.PP
+.CS
+\fBuplevel\fR {set x 42}
+.CE
+.PP
+then the \fBset\fR command will modify the same variable \fBx\fR in \fBb\fR's
+context:  the procedure \fBc\fR does not appear to be on the call stack
+when \fBd\fR is executing.  The \fBinfo level\fR command may
+be used to obtain the level of the current procedure.
+.PP
+\fBUplevel\fR makes it possible to implement new control
+constructs as Tcl procedures (for example, \fBuplevel\fR could
+be used to implement the \fBwhile\fR construct as a Tcl procedure).
+.PP
+The \fBnamespace eval\fR and \fBapply\fR commands offer other ways
+(besides procedure calls) that the Tcl naming context can change.
+They add a call frame to the stack to represent the namespace context.
+This means each \fBnamespace eval\fR command
+counts as another call level for \fBuplevel\fR and \fBupvar\fR commands.
+For example, \fBinfo level 1\fR will return a list
+describing a command that is either
+the outermost procedure call or the outermost \fBnamespace eval\fR command.
+Also, \fBuplevel #0\fR evaluates a script
+at top-level in the outermost namespace (the global namespace).
+.SH EXAMPLE
+As stated above, the \fBuplevel\fR command is useful for creating new
+control constructs.  This example shows how (without error handling)
+it can be used to create a \fBdo\fR command that is the counterpart of
+\fBwhile\fR except for always performing the test after running the
+loop body:
+.PP
+.CS
+proc do {body while condition} {
+    if {$while ne "while"} {
+        error "required word missing"
+    }
+    set conditionCmd [list expr $condition]
+    while {1} {
+        \fBuplevel\fR 1 $body
+        if {![\fBuplevel\fR 1 $conditionCmd]} {
+            break
+        }

+upvar \- Create link to variable in a different stack frame
+.SH SYNOPSIS
+\fBupvar \fR?\fIlevel\fR? \fIotherVar myVar \fR?\fIotherVar myVar \fR...?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command arranges for one or more local variables in the current
+procedure to refer to variables in an enclosing procedure call or
+to global variables.
+\fILevel\fR may have any of the forms permitted for the \fBuplevel\fR
+command, and may be omitted (it defaults to \fB1\fR).
+For each \fIotherVar\fR argument, \fBupvar\fR makes the variable
+by that name in the procedure frame given by \fIlevel\fR (or at
+global level, if \fIlevel\fR is \fB#0\fR) accessible
+in the current procedure by the name given in the corresponding
+\fImyVar\fR argument.
+The variable named by \fIotherVar\fR need not exist at the time of the
+call;  it will be created the first time \fImyVar\fR is referenced, just like
+an ordinary variable.  There must not exist a variable by the
+name \fImyVar\fR at the time \fBupvar\fR is invoked.
+\fIMyVar\fR is always treated as the name of a variable, not an
+array element.  An error is returned if the name looks like an array element,
+such as \fBa(b)\fR.
+\fIOtherVar\fR may refer to a scalar variable, an array,
+or an array element.
+\fBUpvar\fR returns an empty string.
+.PP
+The \fBupvar\fR command simplifies the implementation of call-by-name
+procedure calling and also makes it easier to build new control constructs
+as Tcl procedures.
+For example, consider the following procedure:
+.PP
+.CS
+proc \fIadd2\fR name {
+    \fBupvar\fR $name x
+    set x [expr {$x + 2}]
+}
+.CE
+.PP
+If \fIadd2\fR is invoked with an argument giving the name of a variable,
+it adds two to the value of that variable.
+Although \fIadd2\fR could have been implemented using \fBuplevel\fR
+instead of \fBupvar\fR, \fBupvar\fR makes it simpler for \fIadd2\fR
+to access the variable in the caller's procedure frame.
+.PP
+\fBnamespace eval\fR is another way (besides procedure calls)
+that the Tcl naming context can change.
+It adds a call frame to the stack to represent the namespace context.
+This means each \fBnamespace eval\fR command
+counts as another call level for \fBuplevel\fR and \fBupvar\fR commands.
+For example, \fBinfo level\fR \fB1\fR will return a list
+describing a command that is either
+the outermost procedure call or the outermost \fBnamespace eval\fR command.
+Also, \fBuplevel #0\fR evaluates a script
+at top-level in the outermost namespace (the global namespace).
+.PP
+If an upvar variable is unset (e.g. \fBx\fR in \fBadd2\fR above), the
+\fBunset\fR operation affects the variable it is linked to, not the
+upvar variable.  There is no way to unset an upvar variable except
+by exiting the procedure in which it is defined.  However, it is
+possible to retarget an upvar variable by executing another \fBupvar\fR
+command.
+.SH "TRACES AND UPVAR"
+.PP
+Upvar interacts with traces in a straightforward but possibly
+unexpected manner.  If a variable trace is defined on \fIotherVar\fR, that
+trace will be triggered by actions involving \fImyVar\fR.  However,
+the trace procedure will be passed the name of \fImyVar\fR, rather
+than the name of \fIotherVar\fR.  Thus, the output of the following code
+will be
+.QW "\fIlocalVar\fR"
+rather than
+.QW "\fIoriginalVar\fR" :
+.PP
+.CS
+proc \fItraceproc\fR { name index op } {
+    puts $name
+}
+proc \fIsetByUpvar\fR { name value } {
+    \fBupvar\fR $name localVar
+    set localVar $value
+}
+set originalVar 1
+trace variable originalVar w \fItraceproc\fR
+\fIsetByUpvar\fR originalVar 2
+.CE
+.PP
+If \fIotherVar\fR refers to an element of an array, then variable
+traces set for the entire array will not be invoked when \fImyVar\fR
+is accessed (but traces on the particular element will still be
+invoked).  In particular, if the array is \fBenv\fR, then changes
+made to \fImyVar\fR will not be passed to subprocesses correctly.
+.SH EXAMPLE
+A \fBdecr\fR command that works like \fBincr\fR except it subtracts
+the value from the variable instead of adding it:
+.PP
+.CS
+proc decr {varName {decrement 1}} {
+    \fBupvar\fR 1 $varName var
+    incr var [expr {-$decrement}]

+.SH SYNOPSIS
+\fBvariable \fR\fIname\fR
+.sp
+\fBvariable \fR?\fIname value...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+This command is normally used within a
+\fBnamespace eval\fR command to create one or more variables
+within a namespace.
+Each variable \fIname\fR is initialized with \fIvalue\fR.
+The \fIvalue\fR for the last variable is optional.
+.PP
+If a variable \fIname\fR does not exist, it is created.
+In this case, if \fIvalue\fR is specified,
+it is assigned to the newly created variable.
+If no \fIvalue\fR is specified, the new variable is left undefined.
+If the variable already exists,
+it is set to \fIvalue\fR if \fIvalue\fR is specified
+or left unchanged if no \fIvalue\fR is given.
+Normally, \fIname\fR is unqualified
+(does not include the names of any containing namespaces),
+and the variable is created in the current namespace.
+If \fIname\fR includes any namespace qualifiers,
+the variable is created in the specified namespace.  If the variable
+is not defined, it will be visible to the \fBnamespace which\fR
+command, but not to the \fBinfo exists\fR command.
+.PP
+If the \fBvariable\fR command is executed inside a Tcl procedure,
+it creates local variables
+linked to the corresponding namespace variables (and therefore these
+variables are listed by \fBinfo vars\fR.)
+In this way the \fBvariable\fR command resembles the \fBglobal\fR command,
+although the \fBglobal\fR command
+only links to variables in the global namespace.
+If any \fIvalue\fRs are given,
+they are used to modify the values of the associated namespace variables.
+If a namespace variable does not exist,
+it is created and optionally initialized.
+.PP
+A \fIname\fR argument cannot reference an element within an array.
+Instead, \fIname\fR should reference the entire array,
+and the initialization \fIvalue\fR should be left off.
+After the variable has been declared,
+elements within the array can be set using ordinary
+\fBset\fR or \fBarray\fR commands.

+.SH NAME
+vwait \- Process events until a variable is written
+.SH SYNOPSIS
+\fBvwait\fR \fIvarName\fR
+.BE
+.SH DESCRIPTION
+.PP
+This command enters the Tcl event loop to process events, blocking
+the application if no events are ready.  It continues processing
+events until some event handler sets the value of the global variable
+\fIvarName\fR.  Once \fIvarName\fR has been set, the \fBvwait\fR
+command will return as soon as the event handler that modified
+\fIvarName\fR completes.  The \fIvarName\fR argument is always interpreted as
+a variable name with respect to the global namespace, but can refer to any
+namespace's variables if the fully-qualified name is given.
+.PP
+In some cases the \fBvwait\fR command may not return immediately
+after \fIvarName\fR is set.  This happens if the event handler
+that sets \fIvarName\fR does not complete immediately.  For example,
+if an event handler sets \fIvarName\fR and then itself calls
+\fBvwait\fR to wait for a different variable, then it may not return
+for a long time.  During this time the top-level \fBvwait\fR is
+blocked waiting for the event handler to complete, so it cannot
+return either. (See the \fBNESTED VWAITS BY EXAMPLE\fR below.)
+.PP
+To be clear, \fImultiple \fBvwait\fI calls will nest and will not happen in
+parallel\fR.  The outermost call to \fBvwait\fR will not return until all the
+inner ones do.  It is recommended that code should never nest \fBvwait\fR
+calls (by avoiding putting them in event callbacks) but when that is not
+possible, care should be taken to add interlock variables to the code to
+prevent all reentrant calls to \fBvwait\fR that are not \fIstrictly\fR
+necessary. Be aware that the synchronous modes of operation of some Tcl
+packages (e.g.,\ \fBhttp\fR) use \fBvwait\fR internally; if using the event
+loop, it is best to use the asynchronous callback-based modes of operation of
+those packages where available.
+.SH EXAMPLES
+.PP
+Run the event-loop continually until some event calls \fBexit\fR.
+(You can use any variable not mentioned elsewhere, but the name
+\fIforever\fR reminds you at a glance of the intent.)

+.SS "NESTED VWAITS BY EXAMPLE"
+.PP
+This example demonstrates what can happen when the \fBvwait\fR command is
+nested. The script will never finish because the waiting for the \fIa\fR
+variable never finishes; that \fBvwait\fR command is still waiting for a
+script scheduled with \fBafter\fR to complete, which just happens to be
+running an inner \fBvwait\fR (for \fIb\fR) even though the event that the
+outer \fBvwait\fR was waiting for (the setting of \fIa\fR) has occurred.

+set b 42
+.CE
+.PP
+If you run the above code, you get this output:

+waiting for a
+waiting for b

+.CE
+.PP
+The script will never print
+.QW "a was set"
+until after it has printed
+.QW "b was set"
+because of the nesting of \fBvwait\fR commands, and yet \fIb\fR will not be
+set until after the outer \fBvwait\fR returns, so the script has deadlocked.
+The only ways to avoid this are to either structure the overall program in
+continuation-passing style or to use \fBcoroutine\fR to make the continuations
+implicit. The first of these options would be written as:
+.PP
+.CS
+after 500 {
+    puts "waiting for b"
+    trace add variable b write {apply {args {
+        global a b

+\fBwhile \fItest body\fR
+.BE
+.SH DESCRIPTION
+.PP
+The \fBwhile\fR command evaluates \fItest\fR as an expression
+(in the same way that \fBexpr\fR evaluates its argument).
+The value of the expression must a proper boolean
+value; if it is a true value
+then \fIbody\fR is executed by passing it to the Tcl interpreter.
+Once \fIbody\fR has been executed then \fItest\fR is evaluated
+again, and the process repeats until eventually \fItest\fR
+evaluates to a false boolean value.  \fBContinue\fR
+commands may be executed inside \fIbody\fR to terminate the current
+iteration of the loop, and \fBbreak\fR
+commands may be executed inside \fIbody\fR to cause immediate
+termination of the \fBwhile\fR command.  The \fBwhile\fR command
+always returns an empty string.
+.PP
+Note: \fItest\fR should almost always be enclosed in braces.  If not,
+variable substitutions will be made before the \fBwhile\fR
+command starts executing, which means that variable changes
+made by the loop body will not be considered in the expression.
+This is likely to result in an infinite loop.  If \fItest\fR is
+enclosed in braces, variable substitutions are delayed until the
+expression is evaluated (before
+each loop iteration), so changes in the variables will be visible.
+For an example, try the following script with and without the braces
+around \fB$x<10\fR:

+zlib \- compression and decompression operations
+.SH SYNOPSIS
+.nf
+\fBzlib \fIsubcommand arg ...\fR
+.fi
+.BE
+.SH DESCRIPTION
+.PP
+The \fBzlib\fR command provides access to the compression and check-summing
+facilities of the Zlib library by Jean-loup Gailly and Mark Adler. It has the
+following subcommands.
+.SS "COMPRESSION SUBCOMMANDS"
+.TP
+\fBzlib compress\fI string\fR ?\fIlevel\fR?
+.
+Returns the zlib-format compressed binary data of the binary string in
+\fIstring\fR. If present, \fIlevel\fR gives the compression level to use (from
+0, which is uncompressed, to 9, maximally compressed).
+.TP
+\fBzlib decompress\fI string\fR ?\fIbufferSize\fR?
+.
+Returns the uncompressed version of the raw compressed binary data in
+\fIstring\fR. If present, \fIbufferSize\fR is a hint as to what size of buffer
+is to be used to receive the data.
+.TP
+\fBzlib deflate\fI string\fR ?\fIlevel\fR?
+.
+Returns the raw compressed binary data of the binary string in \fIstring\fR.
+If present, \fIlevel\fR gives the compression level to use (from 0, which is
+uncompressed, to 9, maximally compressed).
+.TP
+\fBzlib gunzip\fI string\fR ?\fB\-headerVar \fIvarName\fR?
+.
+Return the uncompressed contents of binary string \fIstring\fR, which must
+have been in gzip format. If \fB\-headerVar\fR is given, store a dictionary
+describing the contents of the gzip header in the variable called
+\fIvarName\fR. The keys of the dictionary that may be present are:
+.RS
+.TP
+\fBcomment\fR
+.
+The comment field from the header, if present.
+.TP
+\fBcrc\fR
+.
+A boolean value describing whether a CRC of the header is computed.
+.TP
+\fBfilename\fR
+.
+The filename field from the header, if present.
+.TP
+\fBos\fR
+.
+The operating system type code field from the header (if not the
+QW unknown
+value). See RFC 1952 for the meaning of these codes.
+.TP
+\fBsize\fR
+.
+The size of the uncompressed data.
+.TP
+\fBtime\fR
+.
+The time field from the header if non-zero, expected to be time that the file
+named by the \fBfilename\fR field was modified. Suitable for use with
+\fBclock format\fR.
+.TP
+\fBtype\fR
+.
+The type of the uncompressed data (\fBbinary\fR or \fBtext\fR) if known.
+.RE
+.TP
+\fBzlib gzip\fI string\fR ?\fB\-level \fIlevel\fR? ?\fB\-header \fIdict\fR? 
+.
+Return the compressed contents of binary string \fIstring\fR in gzip format.
+If \fB\-level\fR is given, \fIlevel\fR gives the compression level to use
+(from 0, which is uncompressed, to 9, maximally compressed). If \fB\-header\fR
+is given, \fIdict\fR is a dictionary containing values used for the gzip
+header. The following keys may be defined:
+.RS
+.TP
+\fBcomment\fR
+.
+Add the given comment to the header of the gzip-format data.
+.TP
+\fBcrc\fR
+.
+A boolean saying whether to compute a CRC of the header. Note that if the data
+is to be interchanged with the \fBgzip\fR program, a header CRC should
+\fInot\fR be computed.
+.TP
+\fBfilename\fR
+.
+The name of the file that the data to be compressed came from.
+.TP
+\fBos\fR
+.
+The operating system type code, which should be one of the values described in
+RFC 1952.
+.TP
+\fBtime\fR
+.
+The time that the file named in the \fBfilename\fR key was last modified. This
+will be in the same as is returned by \fBclock seconds\fR or \fBfile mtime\fR.
+.TP
+\fBtype\fR
+.
+The type of the data being compressed, being \fBbinary\fR or \fBtext\fR.
+.RE
+.TP
+\fBzlib inflate\fI string\fR ?\fIbufferSize\fR?
+.
+Returns the uncompressed version of the raw compressed binary data in
+\fIstring\fR. If present, \fIbufferSize\fR is a hint as to what size of buffer
+is to be used to receive the data.
+.SS "CHANNEL SUBCOMMAND"
+.TP
+\fBzlib push\fI mode channel\fR ?\fIoptions ...\fR?
+.
+Pushes a compressing or decompressing transformation onto the channel
+\fIchannel\fR.
+The transformation can be removed again with \fBchan pop\fR.
+The \fImode\fR argument determines what type of transformation
+is pushed; the following are supported:
+.RS
+.TP
+\fBcompress\fR
+.
+The transformation will be a compressing transformation that produces
+zlib-format data on \fIchannel\fR, which must be writable.
+.TP
+\fBdecompress\fR
+.
+The transformation will be a decompressing transformation that reads
+zlib-format data from \fIchannel\fR, which must be readable.
+.TP
+\fBdeflate\fR
+.
+The transformation will be a compressing transformation that produces raw
+compressed data on \fIchannel\fR, which must be writable.
+.TP
+\fBgunzip\fR
+.
+The transformation will be a decompressing transformation that reads
+gzip-format data from \fIchannel\fR, which must be readable.
+.TP
+\fBgzip\fR
+.
+The transformation will be a compressing transformation that produces
+gzip-format data on \fIchannel\fR, which must be writable.
+.TP
+\fBinflate\fR
+.
+The transformation will be a decompressing transformation that reads raw
+compressed data from \fIchannel\fR, which must be readable.
+.PP
+The following options may be set when creating a transformation via
+the
+.QW "\fIoptions ...\fR"
+to the \fBzlib push\fR command:
+.TP
+\fB\-dictionary\fI binData\fR
+.VS "TIP 400"
+Sets the compression dictionary to use when working with compressing or
+decompressing the data to be \fIbinData\fR. Not valid for transformations that
+work with gzip-format data.
+.VE
+.TP
+\fB\-header\fI dictionary\fR
+.
+Passes a description of the gzip header to create, in the same format that
+\fBzlib gzip\fR understands.
+.TP
+\fB\-level\fI compressionLevel\fR
+.
+How hard to compress the data. Must be an integer from 0 (uncompressed) to 9
+(maximally compressed).
+.TP
+\fB\-limit\fI readaheadLimit\fR
+.
+The maximum number of bytes ahead to read when decompressing. This defaults to
+1, which ensures that data is always decompressed correctly, but may be
+increased to improve performance. This is more useful when the channel is
+non-blocking.
+.PP
+Both compressing and decompressing channel transformations add extra
+configuration options that may be accessed through \fBchan configure\fR. The
+options are:
+.TP
+\fB\-checksum\fI checksum\fR
+.
+This read-only option gets the current checksum for the uncompressed data that
+the compression engine has seen so far. It is valid for both compressing and
+decompressing transforms, but not for the raw inflate and deflate formats. The
+compression algorithm depends on what format is being produced or consumed.
+.TP
+\fB\-dictionary\fI binData\fR
+.VS "TIP 400"
+This read-write options gets or sets the compression dictionary to use when
+working with compressing or decompressing the data to be \fIbinData\fR. It is
+not valid for transformations that work with gzip-format data, and should not
+normally be set on compressing transformations other than at the point where
+the transformation is stacked.
+.VE
+.TP
+\fB\-flush\fI type\fR
+.
+This write-only operation flushes the current state of the compressor to the
+underlying channel. It is only valid for compressing transformations. The
+\fItype\fR must be either \fBsync\fR or \fBfull\fR for a normal flush or an
+expensive flush respectively. Flushing degrades the compression ratio, but
+makes it easier for a decompressor to recover more of the file in the case of
+data corruption.
+.TP
+\fB\-header\fI dictionary\fR
+.
+This read-only option, only valid for decompressing transforms that are
+processing gzip-format data, returns the dictionary describing the header read
+off the data stream.
+.TP
+\fB\-limit\fI readaheadLimit\fR
+.
+This read-write option is used by decompressing channels to control the
+maximum number of bytes ahead to read from the underlying data source. This
+defaults to 1, which ensures that data is always decompressed correctly, but
+may be increased to improve performance. This is more useful when the channel
+is non-blocking.
+.RE
+.SS "STREAMING SUBCOMMAND"
+.TP
+\fBzlib stream\fI mode\fR ?\fIoptions\fR?
+.
+Creates a streaming compression or decompression command based on the
+\fImode\fR, and return the name of the command. For a description of how that
+command works, see \fBSTREAMING INSTANCE COMMAND\fR below. The following modes
+and \fIoptions\fR are supported:
+.RS
+.TP
+\fBzlib stream compress\fR ?\fB\-dictionary \fIbindata\fR? ?\fB\-level \fIlevel\fR?
+.
+The stream will be a compressing stream that produces zlib-format output,
+using compression level \fIlevel\fR (if specified) which will be an integer
+from 0 to 9,
+.VS "TIP 400"
+and the compression dictionary \fIbindata\fR (if specified).
+.VE
+.TP
+\fBzlib stream decompress\fR ?\fB\-dictionary \fIbindata\fR?
+.
+The stream will be a decompressing stream that takes zlib-format input and
+produces uncompressed output.
+.VS "TIP 400"
+If \fIbindata\fR is supplied, it is a compression dictionary to use if
+required.
+.VE
+.TP
+\fBzlib stream deflate\fR ?\fB\-dictionary \fIbindata\fR? ?\fB\-level \fIlevel\fR?
+.
+The stream will be a compressing stream that produces raw output, using
+compression level \fIlevel\fR (if specified) which will be an integer from 0
+to 9,
+.VS "TIP 400"
+and the compression dictionary \fIbindata\fR (if specified). Note that
+the raw compressed data includes no metadata about what compression
+dictionary was used, if any; that is a feature of the zlib-format data.
+.VE
+.TP
+\fBzlib stream gunzip\fR
+.
+The stream will be a decompressing stream that takes gzip-format input and
+produces uncompressed output.
+.TP
+\fBzlib stream gzip\fR ?\fB\-header \fIheader\fR? ?\fB\-level \fIlevel\fR?
+.
+The stream will be a compressing stream that produces gzip-format output,
+using compression level \fIlevel\fR (if specified) which will be an integer
+from 0 to 9, and the header descriptor dictionary \fIheader\fR (if specified;
+for keys see \fBzlib gzip\fR).
+.TP
+\fBzlib stream inflate\fR ?\fB\-dictionary \fIbindata\fR?
+.
+The stream will be a decompressing stream that takes raw compressed input and
+produces uncompressed output.
+.VS "TIP 400"
+If \fIbindata\fR is supplied, it is a compression dictionary to use. Note that
+there are no checks in place to determine whether the compression dictionary
+is correct.
+.VE
+.RE
+.SS "CHECKSUMMING SUBCOMMANDS"
+.TP
+\fBzlib adler32\fI string\fR ?\fIinitValue\fR?
+.
+Compute a checksum of binary string \fIstring\fR using the Adler-32 algorithm.
+If given, \fIinitValue\fR is used to initialize the checksum engine.
+.TP
+\fBzlib crc32\fI string\fR ?\fIinitValue\fR?
+.
+Compute a checksum of binary string \fIstring\fR using the CRC-32 algorithm.
+If given, \fIinitValue\fR is used to initialize the checksum engine.
+.SH "STREAMING INSTANCE COMMAND"
+.PP
+Streaming compression instance commands are produced by the \fBzlib stream\fR
+command. They are used by calling their \fBput\fR subcommand one or more times
+to load data in, and their \fBget\fR subcommand one or more times to extract
+the transformed data.
+.PP
+The full set of subcommands supported by a streaming instance command,
+\fIstream\fR, is as follows:
+.TP
+\fIstream \fBadd\fR ?\fIoption...\fR? \fIdata\fR
+.
+A short-cut for
+.QW "\fIstream \fBput \fR?\fIoption...\fR? \fIdata\fR"
+followed by
+.QW "\fIstream \fBget\fR" .
+.TP
+\fIstream \fBchecksum\fR
+.
+Returns the checksum of the uncompressed data seen so far by this stream.
+.TP
+\fIstream \fBclose\fR
+.
+Deletes this stream and frees up all resources associated with it.
+.TP
+\fIstream \fBeof\fR
+.
+Returns a boolean indicating whether the end of the stream (as determined by

+detection of the end of the stream.
+.TP
+\fIstream \fBfinalize\fR
+.
+A short-cut for
+.QW "\fIstream \fBput \-finalize {}\fR" .
+.TP
+\fIstream \fBflush\fR
+.
+A short-cut for
+.QW "\fIstream \fBput \-flush {}\fR" .
+.TP
+\fIstream \fBfullflush\fR
+.
+A short-cut for
+.QW "\fIstream \fBput \-fullflush {}\fR" .
+.TP
+\fIstream \fBget \fR?\fIcount\fR?
+.
+Return up to \fIcount\fR bytes from \fIstream\fR's internal buffers with the
+transformation applied. If \fIcount\fR is omitted, the entire contents of the
+buffers are returned.
+.
+\fIstream \fBheader\fR
+.
+Return the gzip header description dictionary extracted from the stream. Only
+supported for streams created with their \fImode\fR parameter set to
+\fBgunzip\fR.
+.TP
+\fIstream \fBput\fR ?\fIoption...\fR? \fIdata\fR
+.
+Append the contents of the binary string \fIdata\fR to \fIstream\fR's internal
+buffers while applying the transformation. The following \fIoption\fRs are
+supported (or an unambiguous prefix of them), which are used to modify the
+way in which the transformation is applied:
+.RS
+.TP
+\fB\-dictionary\fI binData\fR
+.VS "TIP 400"
+Sets the compression dictionary to use when working with compressing or
+decompressing the data to be \fIbinData\fR.
+.VE
+.TP
+\fB\-finalize\fR
+.
+Mark the stream as finished, ensuring that all bytes have been wholly
+compressed or decompressed. For gzip streams, this also ensures that the
+footer is written to the stream. The stream will need to be reset before
+having more data written to it after this, though data can still be read out
+of the stream with the \fBget\fR subcommand.
+.RS
+.PP
+This option is mutually exclusive with the \fB\-flush\fR and \fB\-fullflush\fR
+options.
+.RE

+stream is producing will be able to produce all the bytes that have been
+compressed so far, at some performance penalty.
+.RS
+.PP
+This option is mutually exclusive with the \fB\-finalize\fR and
+\fB\-fullflush\fR options.
+.RE
+.TP
+\fB\-fullflush\fR
+.
+Ensure that not only can a decompressor handle all the bytes produced so far
+(as with \fB\-flush\fR above) but also that it can restart from this point if
