2009-10-27  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl (ParseClockScanFormat):
	Corrected a problem where [clock scan] didn't load the timezone
	soon enough when processing a time format that lacked a complete
	date. [Bug 2886852]
	* tests/clock.test (clock-66.1):
	Added a test case for the above bug.
	* library/tzdata/America/Argentina/Buenos_Aires:
	* library/tzdata/America/Argentina/Cordoba:
	* library/tzdata/America/Argentina/San_Luis:
	* library/tzdata/America/Argentina/Tucuman: 
	New DST rules for Argentina. (Olson's tzdata2009p.)
	
2009-10-24  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl (ProcessPosixTimeZone): 
	Corrected a regression in the fix to [Bug 2207436] that caused
	[clock] to apply EU daylight saving time rules in the US.  Thanks
	to Karl Lehenbauer for reporting this regression.
	* tests/clock.test (clock-52.4):
	Added a regression test for the above regression.
	* library/tzdata/Asia/Dhaka:
	* library/tzdata/Asia/Karachi:
	New DST rules for Bangladesh and Pakistan. (Olson's tzdata2009o.)
	
2009-10-23  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (FlushChannel): Skip OutputProc for low-level
	0-length writes. When closing pipes which have already been closed
	not skipping leads to spurious SIG_PIPE signals. Reported by
	Mikhail Teterin <mi+thun@aldan.algebra.com>.

2009-10-21  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclPosixStr.c: [Bug 2882561]: Work around oddity on Haiku OS
	where SIGSEGV and SIGBUS are the same value.

2009-10-19  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclIO.c:	Revised ReadChars and FilterInputBytes routines
	to permit reads to continue up to the string limits of Tcl values.
	Before revisions, large read attempts could panic when as little as
	half the limiting value length was reached.  [Patch 2107634]
	Thanks to Sean Morrison and Bob Parker for their roles in the fix.

2009-10-18  Joe Mistachkin  <joe@mistachkin.com>

	* tests/thread.test (thread-4.[345]): [Bug 1565466]: Correct tests to
	save their error state before the final call to threadReap just in case
	it triggers an "invalid thread id" error.  This error can occur if one
	or more of the target threads has exited prior to the attempt to send
	it an asynchronous exit command.

	* doc/memory.n: [Bug 988703]: Add mechanism for discovering what Tcl_Objs
	* generic/tclCkalloc.c (MemoryCmd): are allocated when built for memory
	* generic/tclInt.decls: debugging.  This was previously backported from
	* generic/tclInt.h: Tcl 8.6 with the corrections to fix [Bug 2871908].
	* generic/tclObj.c (ObjData, TclFinalizeThreadObjects): However, there
	were key elements missing.  These changes make things consistent between
	branches.

2009-10-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclVar.c (TclDeleteCompiledLocalVars, UnsetVarStruct)
	(TclDeleteNamespaceVars): 
	* generic/tclTrace.c (Tcl_UntraceVar2): [Bug 2629338]: Stop traces
	that are deleted part way through (a feature used by tdom) from
	causing freed memory to be accessed.

2009-10-08  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclDictObj.c (DictIncrCmd): [Bug 2874678]: Don't leak any
	bignums when doing [dict incr] with a value.
	* tests/dict.test (dict-19.3): Memory leak detection code.

2009-10-07  Andreas Kupries  <andreask@activestate.com>

	* generic/tclObj.c: [Bug 2871908]: Plug memory leaks of the
	objThreadMap and lineCLPtr hashtables.  Also make the names of the
	continuation line information initialization and finalization
	functions more consistent. Patch supplied by Joe Mistachkin
	<joe@mistachkin.com>.

	* generic/tclIORChan.c (ErrnoReturn): Replace the hardwired constant
	11 with the proper errno define, EAGAIN. What was I thinking? The
	BSD's have a different errno assignment and break with the hardwired
	number. Reported by emiliano on the chat.

2009-10-06  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclTomMathInt.h (new): Public header tclTomMath.h had
	* generic/tclTomMath.h: dependence on private headers, breaking use
	* generic/tommath.h:    by extensions [Bug 1941434].

2009-10-05  Don Porter  <dgp@users.sourceforge.net>

	* changes:	Update for 8.5.8 release.

2009-10-04  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/tclMacOSXBundle.c:	Workaround CF memory managment bug in
	* unix/tclUnixInit.c:		Mac OS X 10.4 & earlier. [Bug 2569449]

2009-10-02  Kevin B. Kenny  <kennykb@acm.org>

	* library/tzdata/Africa/Cairo:
	* library/tzdata/Asia/Gaza:
	* library/tzdata/Asia/Karachi:
	* library/tzdata/Pacific/Apia:	Olson's tzdata2009n.

2009-08-24  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/tclMacOSXNotify.c: Fix multiple issues with nested event loops
	when CoreFoundation notifier is running in embedded mode. (Fixes
	problems in TkAqua Cocoa reported by Youness Alaoui on tcl-mac)

2009-08-21  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclFileName.c: Correct regression in [Bug 2837800] fix.
	* tests/fileName.test:

2009-08-20  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclFileName.c: [Bug 2837800]: Get the correct result from
	[glob */test] when * matches something like ~foo.

	* generic/tclPathObj.c:	[Bug 2806250]: Prevent the storage of strings
	starting with ~ in the "tail" part (normPathPtr field) of the path
	intrep when PATHFLAGS != 0.  This establishes the assumptions relied
	on elsewhere that the name stored there is a relative path.  Also
	refactored to make an AppendPath() routine instead of the cut/paste
	stanzas that were littered throughout.

2009-08-20  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Plug memory leak.

2009-08-18  Don Porter  <dgp@users.sourceforge.net>

2009-08-06  Andreas Kupries  <andreask@activestate.com>

	* doc/refchan.n [Bug 2827000]: Extended the implementation of
	* generic/tclIORChan.c: reflective channels (TIP 219, method 'read'),
	* tests/ioCmd.test: enabling handlers to signal EAGAIN to indicate 'no
	data, but not at EOF either', and other system errors. Updated

	* generic/tclIO.c (Tcl_GetChannelHandle): [Bug 2826248]: Do not crash
	* generic/tclPipe.c (FileForRedirect): for getHandleProc == NULL, this
	is allowed. Provide a nice error message in the bypass area. Updated
	caller to check the bypass for a mesage. Bug reported by Andy

2009-07-20  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdMZ.c (StringIsCmd): Reorganize so that [string is] is
	more efficient when parsing things that are correct, at a cost of
	making the empty string test slightly more costly. With this, the cost
	of doing [string is integer -strict $x] matches [catch {expr {$x+0}}]
	in the successful case, and greatly outstrips it in the failing case.

2009-07-16  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdIL.c:	Removed unused variables.
	* generic/tclCompile.c:

	register on MIPS systems so that the gradual underflow expected by Tcl
	is in effect.

	* generic/tclExecute.c (TclExecuteByteCode):
	* generic/tclInt.h (ExtIndex, CFWordBC):
	* tests/info.test (info-39.0):

	Backport of some changes made to the Tcl head, to handle literal
	sharing better. The code here is much simpler (trimmed down) compared
	to the head as the 8.5 branch is not bytecode compiling whole files,
	and doesn't compile eval'd code either.
	
	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
	removes the problems with location data caused by literal sharing in
	proc bodies. Simplified the associated datastructures (ExtIndex is
	gone, as is the function EnterCmdWordIndex).

2009-07-01  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/tclWinInt.h:   [Bug 2806622]: Handle the GetUserName API call
	* win/tclWin32Dll.c: via the tclWinProcs indirection structure. This
	* win/tclWinInit.c:  fixes a problem obtaining the username when the
	USERNAME environment variable is unset.

2009-06-15  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c: sprintf() -> Tcl_ObjPrintf() conversion.

2009-06-13  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompile.c:	The value stashed in iPtr->compiledProcPtr
	* generic/tclProc.c:	when compiling a proc survives too long.  We
	* tests/execute.test:	only need it there long enough for the right
	TclInitCompileEnv() call to re-stash it into envPtr->procPtr.  Once
	that is done, the CompileEnv controls.  If we let the value of
	iPtr->compiledProcPtr linger, though, then any other bytecode compile
	operation that takes place will also have its CompileEnv initialized
	with it, and that's not correct.  The value is meant to control the
	compile of the proc body only, not other compile tasks that happen
	along.  Thanks to Carlos Tasada for discovering and reporting the
	problem.  [Bug 2802881].

2009-06-10  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:	Revised [format] to not overflow the
	integer calculations computing the length of the %ll formats of
	really big integers.  Also added protections so that [format]s that
	would produce results overflowing the maximum string length of Tcl
	values throw a normal Tcl error instead of a panic. [Bug 2801413]

2006-06-09  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclGetDate.y: Fixed a thread safety bug in the generated
	* library/clock.tcl:    Bison parser (needed a %pure-parser
	* tests/clock.test:     declaration to avoid static variables).
				Discovered that the %pure-parser declaration
	                        allowed for returning the Bison error message
	                        to the Tcl caller in the event of a syntax
	                        error, so did so.
	* generic/tclDate.c: bison 2.3

	* generic/tclExecute.c:	Replace dynamically-initialized table with
	a table of static constants in the lookup table for exponent operator
	computations that fit in a 64 bit integer result.

	* generic/tclExecute.c:	Corrected implementations and selection
	logic of the INST_EXPON instruction to fix [Bug 2798543].

2009-06-01  Don Porter  <dgp@users.sourceforge.net>

	* tests/expr.test:	Added many tests demonstrating the broken

	through a cached name.
	
2009-05-06  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c:   Improve overflow error message from
	[string repeat].  [Bug 2582327]

2009-04-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tcl.m4, unix/configure (SC_CONFIG_CFLAGS): harden the check
	to add _r to CC on AIX with threads.

2009-04-27  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>

	* generic/tclInt.h:   Backport fix for [Bug 1028264]: WSACleanup() too early.
	* generic/tclEvent.c: The fix introduces "late exit handlers"
	* win/tclWinSock.c:   for similar late process-wide cleanups.

2009-04-27  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>

	* win/tclWinSock.c: Backport fix for [Bug 2446662]: resync Win

2009-04-27  Donal K. Fellows  <dkf@users.sf.net>

	* doc/concat.n (EXAMPLES): [Bug 2780680]: Rewrote so that the spacing
	of result messages is correct. (The exact way they were wrong was
	different when rendered through groff or as HTML, but it was still
	wrong both ways.)

2009-04-24  Stuart Cassoff <stwo@users.sf.net>

	* unix/Makefile.in: [Patch 2769530]: Don't chmod/exec installManPage.

2009-04-15  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:       Added protections from invalid memory
	* generic/tclTestObj.c:         accesses when we append (some part of)

2009-03-20  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:       Test stringObj-6.9 checks that

2009-02-20  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclPathObj.c: Fixed mistaken logic in TclFSGetPathType()
	* tests/fileName.test:  that assumed (not "absolute" => "relative").
	This is a false assumption on Windows, where "volumerelative" is
	another possibility.  [Bug 2571597].

2009-02-17  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tcl.m4, win/configure: Check if cl groks _WIN64 already to

	Use 'd'ebug runtime in 64-bit builds.

2009-02-05  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c: Added overflow protections to the

2009-02-04  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c (SetUnicodeObj):       Corrected failure of

	* unix/configure: Autoconf 2.59
	
2009-01-21  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIORChan.c (ReflectClose): Fix for [Bug 2458202].
	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.

2009-01-19  Kevin B. Kenny  <kennykb@acm.org>

	* unix/Makefile.in: Added a CONFIG_INSTALL_DIR parameter so that
	* unix/tcl.m4:      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 [Patch 907924].
	* unix/configure: Autoconf 2.59
	
2009-01-09  Don Porter  <dgp@users.sourceforge.net>

2009-01-08  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c (STRING_UALLOC):  Added missing parens
	required to get correct results out of things like

2009-01-06  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclDictObj.c (DictIncrCmd): Corrected twiddling in internals

	Backport of 2008-11-26 commit from Kevin Kenny.

	* win/tclWinThrd.c (TclpThreadCreate): We need to initialize the

	field while windows only fills it with a 32 bit value. The result is
	an inability to join the threads as the ids cannot be matched.
	Backport of 2008-10-13 commit from Pat Thoyts.

2008-12-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclExecute.c (TEBC:INST_DICT_GET): Make sure that the result
	is empty when generating an error message. [Bug 2431847]

2008-12-12  Jan Nijtmans  <nijtmans@users.sf.net>

	* library/clock.tcl (ProcessPosixTimeZone): Fix time change in Eastern
	Europe (not 3:00 but 4:00 local time) [Bug 2207436]

2008-12-11  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (SetChannelFromAny and related): Modified the
	* tests/io.test: internal representation of the tclChannelType to
	contain not only the ChannelState pointer, but also a reference to the
	interpreter it was made in. Invalidate and recompute the internal
	representation when it is used in a different interpreter (like
	cmdName intrep's). Added testcase. [Bug 2407783]

2008-12-11  Jan Nijtmans  <nijtmans@users.sf.net>

	* library/clock.tcl (ProcessPosixTimeZone): Fallback to European time
	zone DST rules, when the timezone is between 0 and -12. [Bug 2207436]

	complete normalization attention for correct results. [Bug 2385549]

2008-12-03  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclFileName.c (DoGlob): One of the Tcl_FSMatchInDirectory
	calls did not have its return code checked. This caused error messages
	returned by some Tcl_Filesystem drivers to be swallowed.

2008-12-02  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (TclFinalizeIOSubsystem): Replaced Alexandre

	map] to get rid of namespace delimiters before caching a scan or
	format procedure. [Bug 2362156]
	* tests/clock.test (clock-64.[12]): Added test cases for the bug that
	was tickled by a namespace delimiter inside a format string.

	to the relevant parts of the code to avoid future desynchronization.

2008-11-04  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclPort.h: remove the ../win/ header dir as the build system

	installed.

2008-10-24  Pat Thoyts  <patthoyts@users.sourceforge.net>

2008-10-16  Don Porter	<dgp@users.sourceforge.net>

	* library/init.tcl:	Revised [unknown] so that it carefully
	preserves the state of the ::errorInfo and ::errorCode variables at
	the start of auto-loading and restores that state before the
	autoloaded command is evaluated. [Bug 2140628]

2008-09-25  Don Porter	<dgp@users.sourceforge.net>

	* doc/global.n:	Correct false claim about [info locals].

2008-09-17  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclInt.h:     Correct the TclGetLongFromObj,

	internalRep.otherValuePtr field to type long.

2008-09-17  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclUtil.c (Tcl_ConcatObj):
	* tests/util.test (util-4.7):
	fix [Bug 1447328]; the original "fix" turned Tcl_ConcatObj() into

						not exists when TclInfoFrame()
						is called from a DTrace probe.

	* tests/msgcat.test:		Fix for ::tcl::mac::locale with
					@modifier (HEAD backport 2008-06-01).

	* tests/fCmd.test (fCmd-6.23):	Made result matching robust when test

	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.vc:

2008-08-11  Andreas Kupries  <andreask@activestate.com>

	* library/tm.tcl: Added a 'package provide' command to the generated
	ifneeded scripts of Tcl Modules, for early detection of conflicts
	between the version specified through the file name and a 'provide'
	command in the module implementation, if any. Note that this change
	also now allows Tcl Modules to not provide a 'provide' command at all,
	and declaring their version only through their filename.

	* generic/tclProc.c (Tcl_ProcObjCmd): Fixed memory leak triggered
	* tests/proc.test: by procbody::test::proc. See [Bug 2043636]. Added a
	test case demonstrating the leak before the fix. Fixed a few spelling
	errors in test descriptions as well.

	which may have been mangled by a (broken?) recompile. Backport from
	the HEAD.

2008-08-04  Don Porter  <dgp@users.sourceforge.net>

	TCL_ALLOW_EXCEPTIONS is tested.

2008-07-29  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c:  fix [Bug 2030670] that cause
	TclStackRealloc to panic on rare corner cases. Thx ajpasadyn for
	diagnose and patch.

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.

2008-07-25  Daniel Steffen  <das@users.sourceforge.net>

	* tests/info.test (info-37.0): Add !singleTestInterp constraint;
	(info-22.8, info-23.0): switch to glob matching to avoid sensitivity
	to tcltest.tcl line number changes, remove knownBug constraint, fix
	expected result. [Bug 1605269]

2008-07-25  Andreas Kupries  <andreask@activestate.com>

	* tests/info.test: Tests 38.* added, exactly testing the tracking of
	location for uplevel scripts.

	* generic/tclCompile.c (TclInitCompileEnv): Reorganized the
	initialization of the #280 location information to match the flow in
	TclEvalObjEx to get more absolute contexts.

	* generic/tclBasic.c (TclEvalObjEx): Moved the pure-list optimization
	out of the eval-direct code path to be done always, i.e. even when a
	compile is requested. This way we do not loose the association between
	#280 location information and the list elements, if any.

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
	* generic/tclCompile.c: of eoFramePtr, doesn't need the line
	* tests/info.test: information, 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.

2008-07-22  Andreas Kupries  <andreask@activestate.com>

	* generic/tclBasic.c: Added missing function comments.

	* generic/tclCompile.c: Made the new TclEnterCmdWordIndex
	* generic/tclCompile.h: static, and ansified.

	* generic/tclBasic.c: Reworked the handling of bytecode literals
	* generic/tclCompile.c: for #280 to fix the abysmal performance
	* generic/tclCompile.h: for deep recursion, replaced the linear
	* generic/tclExecute.c: search through the whole stack with another
	* generic/tclInt.h: hashtable and simplified the data structure used
	by the compiler (array instead of hashtable). Incidentially this also
	fixes the memory leak reported via [Bug 2024937].

2008-07-21  Don Porter  <dgp@users.sourceforge.net>

	* tests/encoding.test:  Make failing tests pass again. [Bug 1972867]

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
	* generic/tclCompCmds.c: absolute location of literal procedure
	* generic/tclCompile.c: arguments, and making this information
	* generic/tclCompile.h: available to uplevel, eval, and
	* generic/tclInterp.c: siblings. This allows proper tracking of
	* generic/tclInt.h: absolute location through custom (Tcl-coded)
	* generic/tclNamesp.c: control structures based on uplevel, etc.
	* generic/tclProc.c:

2008-07-21  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* generic/tclFCmd.c: Inodes on windows are unreliable [Bug 2015723]

2008-07-20  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* 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.

2008-07-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/DictObj.3: Fix error in example. [Bug 2016740]

2008-07-08  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclGet.c:	Corrected out of date comments.

2008-07-07  Andreas Kupries  <andreask@activestate.com>

	* generic/tclCmdIL.c (InfoFrameCmd): Fixed unsafe idiom of setting the
	interp result found by Don Porter.

2008-07-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/regexp.n, doc/regsub.n: Correct examples. [Bug 1982642]

2008-07-04  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.

2008-07-03  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIORChan.c (InvokeTclMethod): Fixed the memory leak
	reported in [Bug 1987821]. Thanks to Miguel for the rpeort and Don
	Porter for tracking the cause down.

2008-07-03  Don Porter  <dgp@users.sourceforge.net>

	* library/package.tcl:  Removed [file readable] testing from
	[tclPkgUnknown] and friends. We find out soon enough whether a file is
	readable when we try to [source] it, and not testing before allows us
	to workaround the bugs on some common filesystems where [file
	readable] lies to us. [Patch 1969717]

	* library/init.tcl:	enabling requiring Tcl Modules in safe
	* tests/safe.test:	interpreters. Fixes [Bug 1999119].

2008-06-25  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/rules.vc:    Backported fix for dde/registry versions and
	* win/makefile.vc: the staticpkg build option

2008-06-24  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclPathObj.c: Fixed some internals management in the "path"
	Tcl_ObjType for the empty string value. Problem led to a crash in the
	command [glob -dir {} a]. [Bug 1999176].

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 the "translated path" is supposed to do. [Bug 1972879]

2008-06-19  Don Porter  <dgp@users.sourceforge.net>

	* changes:	Update for 8.5.3 release.

	* generic/tclInterp.c:	Fixed completely boneheaded mistake that
	* tests/interp.test:	[interp bgerror $slave] and [$slave bgerror]
	would always act like [interp bgerror {}]. [Bug 1999035]

	* tests/chanio.test:	Corrected flawed tests revealed by a -debug 1
	* tests/event.test:	-singleproc 1 test suite run.
	* tests/io.test:

2008-06-19  Don Porter  <dgp@users.sourceforge.net>

	* changes:	Updates for 8.5.3 release.

2008-06-17  Andreas Kupries  <andreask@activestate.com>

	* generic/tclClock.c (ClockConvertlocaltoutcObjCmd): Removed left
	over debug output.

2008-06-17  Andreas Kupries  <andreask@activestate.com>

	* doc/tm.n: Followup to changelog entry 2008-03-18 regarding
	::tcl::tm::Defaults. Updated the documentation to not only mention
	the new (underscored) form of environment variable names, but make
	it the encouraged form as well. See [Bug 1914604].

2008-06-17  Kevin Kenny  <kennykb@acm.org>

	* generic/tclClock.c (ConvertLocalToUTC):
	* tests/clock.test (clock-63.1): Fixed a bug where the
	internal ConvertLocalToUTC command segfaulted if passed a
	dictionary without the 'localSeconds' key.  To the best of
	my knowledge, the bug was not observable in the [clock]
	command itself.

2008-06-16  Andreas Kupries  <andreask@activestate.com>

	* generic/tclCmdIL.c (TclInfoFrame): Backport of fix made on the
	* tests/info.test: head branch :: Moved the code looking up the
	information for key 'proc' out of the TCL_LOCATION_BC branch to
	after the switch, this is common to all frame types. Updated the
	testsuite to match. This was exposed by the 2008-06-08 commit
	(Miguel), switching uplevel from direct eval to compilation. Fixes
	[Bug 1987851].

2008-06-12  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in:		add complete deps on tclDTrace.h.

	* unix/Makefile.in:		clean generated tclDTrace.h file.
	* 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 debug configs with gcov,
	and with corefoundation disabled; updates and cleanup for Xcode 3.1 and
	for Leopard.
	* macosx/Tcl.xcode/project.pbxproj:	sync Tcl.xcodeproj changes.
	* macosx/README:			document new build configs.

2008-05-26  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/io.test (io-53.9): need to close chan before removing file.

2008-05-23  Andreas Kupries  <andreask@activestate.com>

	* win/tclWinChan.c (FileWideSeekProc): Accepted a patch by
	Alexandre Ferrieux <ferrieux@users.sourceforge.net> to fix the
	[Bug 1965787]. 'tell' now works for locations > 2 GB as well
	instead of going negative.

	* generic/tclIO.c (Tcl_SetChannelBufferSize): Accepted a patch by
	* tests/io.test: Alexandre Ferrieux <ferrieux@users.sourceforge.net>
	* tests/chanio.test: to fix the [Bug 1969953]. Buffersize outside
	of the supported range are now clipped to nearest boundary instead
	of ignored.

2008-05-22  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclNamesp.c (Tcl_LogCommandInfo):	Restored ability to
	handle the argument value length = -1.  Thanks to Chris Darroch for
	discovering the bug and providing the fix.  [Bug 1968245].

2008-05-21  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclParse.c (ParseComment):    The new TclParseAllWhiteSpace
	* tests/parse.test (parse-15.60):       routine has no mechanism to
	return the "incomplete" status of "\\\n" so calling this routine
	anywhere that can be reached within a Tcl_ParseCommand call is a
	mistake. In particular, ParseComment must not use it. [Bug 1968882]

2008-05-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclNamesp.c (Tcl_SetNamespaceUnknownHandler): Corrected odd
	logic for handling installation of namespace unknown handlers which
	could lead too very strange things happening in the error case.

2008-05-16  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompile.c: Fix crash with tcl_traceExec. Found and
	fixed by Alexander Pasadyn [Bug 1964803].

2008-05-07  Donal K. Fellows  <donal.k.fellows@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 value argument was used. Found by Colin
	McCormack.

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.

2008-04-15  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (CopyData): Applied another patch by Alexandre
	* io.test (io-53.8a): Ferrieux <ferrieux@users.sourceforge.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.

2008-04-14  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.

2008-04-11  Don Porter	<dgp@users.sourceforge.net>

	* generic/tcl.h:	Bump version number to 8.5.3b1 to distinguish
	* library/init.tcl:	CVS development snapshots from the 8.5.2 and
	* unix/configure.in:	8.5.3 releases.
	* unix/tcl.spec:
	* win/configure.in:
	* README

	* unix/configure:	autoconf (2.59)
	* win/configure:

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  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.

	* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Added checking of -size
	* tests/ioCmd.test (iocmd-15.{13,14}): value to reject negative
	values, and values overflowing 32-bit signed. [Bug 1557855]. Basic
	patch by Alexandre Ferrieux <ferrieux@users.sourceforge.net>, with
	modifications from me to separate overflow from true negative
	value. Extended testsuite.

2008-04-08  Andreas Kupries  <andreask@activestate.com>

	* tests/io.test (io-53.8): Fixed ordering of vwait and after
	cancel. cancel has to be done after the vwait completes.

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

2008-04-07  Andreas Kupries  <andreask@activestate.com>

	* tests/io.test (io-53.10): Testcase for bi-directionaly fcopy.
	* tests/chanio.test:
	* generic/tclIO.c: Additional changes to data structures for fcopy
	* generic/tclIO.h: and channels to perform proper cleanup in case
	of a channel having two background copy operations running as is
	now possible.

	* tests/io.test (io-53.10): Testcase for bi-directionaly fcopy.
	* generic/tclIO.c: Additional changes to data structures for fcopy
	and channels to perform proper cleanup in case of a channel having
	two background copy operations running as is now possible.

2008-04-07  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (BUSY_STATE, CheckChannelErrors,
	TclCopyChannel): New macro, and the places using it. This change
	allows for bi-directional fcopy on channels. [Bug 1350564]. Thanks
	to Alexandre Ferrieux <ferrieux@users.sourceforge.net> for the
	patch.

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>

	* 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).

	* 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.

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  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (CopyData): Applied patch for the fcopy problem
	[Bug 780533], with many thanks to Alexandre Ferrieux
	<ferrieux@users.sourceforge.net> for tracking it down and
	providing a solution. Still have to convert his test script into a
	proper test case.

2008-04-01  Andreas Kupries  <andreask@activestate.com>

	* generic/tclStrToD.c: Applied patch for [Bug 1839067] (fp
	* unix/tcl.m4: rounding setup on solaris x86, native cc), provided
	* unix/configure: by Michael Schlenker. configure regen'd.

2008-04-01  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclStubLib.c (Tcl_InitStubs):	Added missing error message.
	* generic/tclPkg.c (Tcl_PkgInitStubsCheck):

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>

	*** 8.5.2 TAGGED FOR RELEASE ***

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

	* tests/fCmd.test: Substantial rewrite to use many more tcltest
	features. Great reduction in quantity of [catch] gymnastics. Several
	buggy tests fixed, including one where the result of the previous test
	was being checked!

2008-03-27  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4 (SunOS-5.1x): fix 64bit support for Sun cc. [Bug 1921166]

	* unix/configure: autoconf-2.59

2008-03-26  Don Porter	<dgp@users.sourceforge.net>

	* changes:		Updated for 8.5.2 release.

2008-03-24  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* generic/tclBinary.c: [Bug 1923966] - crash in binary format
	* tests/binary.test:   Added tests for the above crash condition.

2008-03-21  Donal K. Fellows  <dkf@users.sf.net>

	* doc/switch.n: Clarified documentation in respect of two-argument
	invokation. [Bug 1899962]

	* tests/switch.test: Added more tests of regexp-mode compilation of
	the [switch] command. [Bug 1854435]

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>

	* generic/tclExecute.c:	Patch from Miguel Sofer to correct the
	alignment of memory allocated by GrowEvaluationStack(). [Bug 1914503]

2008-03-18  Andreas Kupries  <andreask@activestate.com>

	* library/tm.tcl (::tcl::tm::Defaults): Modified handling of
	environment variables. See [Bug 1914604]. 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.

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
	alignment right. Workaround for [Bug 1914503].

2008-03-14  Reinhard Max  <max@suse.de>

	* generic/tclTest.c:  Ignore the return value of write() when we are
	* unix/tclUnixPipe.c: about to exit anyways.

2008-03-13  Daniel Steffen  <das@users.sourceforge.net>

	* unix/configure.in:	Use backslash-quoting instead of double-quoting
	* unix/tcl.m4:		for lib paths in tclConfig.sh. [Bug 1913622]
	* unix/configure:	autoconf-2.59

2008-03-13  Don Porter	<dgp@users.sourceforge.net>

	* changes:		Updated for 8.5.2 release.

	libm in Cygwin and DJGPP. Thanks to Gordon Schumacher and Philip
	Moore. [Patch 1800636]

2008-03-12  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.xcodeproj/project.pbxproj:	Add support for Xcode 3.1

	* macosx/Tcl-Common.xcconfig:		'xcodebuild install'.

2008-03-12  Andreas Kupries <andreask@activestate.com>

	* doc/http.n, tests/http.test:		Added -keepalive and
	-protocol 1.1 with chunked transfer encoding support. [Bug 1063703,
	1470377, 219225] (default keepalive is 0)
	Added ability to override Host in -headers. [Bug 928154]
	Added -strict option to control URL validation on per-call basis.
	[Bug 1560506]

2008-03-11  Jeff Hobbs  <jeffh@ActiveState.com>

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

	* library/http/http.tcl: Whitespace changes, code cleanup. Allow http
	to be re-sourced without overwriting http state.

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.

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>

	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]

	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]

	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

	* tests/clock.test (clock-61.*, clock-62.1): Regression tests for [Bug
	1862555] and [Bug 1902423].

	* 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  Pat Thoyts  <patthoyts@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
	trying to read from the socket. No clashes found in testing. Added
	http::meta command to access the http headers. [Bug 1868845]

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

	* library/http/pkgIndex.tcl: Set version 2.5.4

	* generic/tclCmdIL.c: More [lsort] data handling streamlines. The
	function MergeSort is gone, essentially inlined into Tcl_LsortObjCmd.
	It is not a straight inlining, two loops over all lists elements where

	merged into the temporary sublists in the same pass.

2007-12-25  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCmdIL.c: More [lsort] data handling streamlines. Extra

	validating channel rep. [Bug 1847044]

2007-12-08  Donal K. Fellows  <dkf@users.sf.net>

	* doc/expr.n, doc/mathop.n: Improved the documentation of the
	operators. [Bug 1823622]

	* generic/tclInt.h: add TclGetChannelFromObj decl
	(TclMatchIsTrivial): simplify TclMatchIsTrivial to remove ] check.

2007-12-06  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>


	* generic/tclBasic.c (Tcl_CreateInterp): Simplify the setting up of
	* generic/tclIOCmd.c (TclInitChanCmd):	 the [chan] ensemble. This
	* library/init.tcl:			 gets rid of quite a bit of
	code and makes it possible to understand the whole with less effort.

	* generic/tclCompCmds.c (TclCompileEnsemble): Ensure that the right
	number of tokens are copied. [Bug 1845320]

	* generic/tclNamesp.c (TclMakeEnsemble): Added missing release of a
	DString. [Bug 1845397]

2007-12-05  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclIO.h:    Create Tcl_Obj for Tcl channels to reduce
	* generic/tclIO.c:    overhead in lookup by Tcl_GetChannel.  New
	* generic/tclIOCmd.c: TclGetChannelFromObj for internal use.
	* generic/tclIO.c (WriteBytes, WriteChars): add opt check to avoid
	EOL translation when not linebuffered or using lf. [Bug 1845092]

2007-12-05  Miguel Sofer  <msofer@users.sf.net>

	* tests/stack.test: made the tests for stack overflow not care
	about which mechanism caused the error (interp's recursion limit
	or C-stack depth detector).

2007-12-05  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/configure, win/tcl.m4 (LIBS_GUI): mingw needs -lole32
	-loleaut32 but not msvc for Tk's [send]. [Bug 1844749]

2007-12-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCmdIL.c (Tcl_LsearchObjCmd): Prevent shimmering crash
	when -exact and -integer/-real are mixed. [Bug 1844789]

2007-12-03  Donal K. Fellows  <dkf@users.sf.net>

	* unix/tclUnixChan.c (CreateSocketAddress): Add extra #ifdef-fery to
	make code compile on BSD 5. [Bug 1618235, again]

2007-12-03  Don Porter	<dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:	Bump tcltest to version 2.3.0 so that
	* library/tcltest/pkgIndex.tcl: we release a stable tcltest with a

2007-12-03  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Adjusted the [switch]
	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd):       command so that when
	passed two arguments, no check for options are performed. This is OK
	since in the two-arg case, detecting an option would definitely lead
	to a syntax error. [Patch 1836519]

2007-11-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/makefile.vc: add ws2_32.lib to baselibs
	* win/configure, win/tcl.m4: add ws2_32.lib / -lws2_32 to build.
	* win/tclWinSock.c: remove dyn loading of winsock, assume that it is
	always available now.

2007-11-29  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclWinSock.c (InitializeHostName):	Correct error in
	buffer length tracking. After gethostname() writes into a buffer,
	convert only the written string to internal encoding, not the whole
	buffer.

2007-11-28  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclConfig.c:	Corrected failure of the [::foo::pkgconfig]
	command to clean up registered configuration data when the query
	command is deleted from the interp. [Bug 983501]

	* generic/tclNamesp.c (Tcl_SetEnsembleMappingDict):	Added checks
	that the dict value passed in is in the format required to make the
	internals of ensembles work. [Bug 1436096]

	* generic/tclIO.c:	Simplify test and improve accuracy of error
	message in latest changes.

2007-11-28  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* generic/tclBasic.c: remove unneeded call in Tcl_CreateInterp, add
	comments.

2007-11-27  Don Porter	<dgp@users.sourceforge.net>

	* win/tclWinSock.c:	Add mising encoding conversion of the [info
	hostname] value from the system encoding to Tcl's internal encoding.

	* doc/chan.n:		"Fix" the limitation on channel -eofchar
	* doc/fconfigure.n:	values to single byte characters by documenting
	* generic/tclIO.c:	it and making it fail loudly. Thanks to Stuart
	* tests/chan.test:	Cassoff for contributing the fix. [Bug 800753]

	Sergei Golovan (aka Teo) for detecting the bug and helping diagnose
	and develop the fix.

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>

	* generic/tclExecute.c (TclExecuteByteCode:INST_EXIST_*): Fix read
	traces not firing on non-existent array elements. [Bug 1833522]

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.

	* generic/tclCompile.c (TclCompileScript): Add the cmdPtr to the list
	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
	interp to Tcl_SetEnsemble* functions.

	* 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>

	* macosx/Tcl.xcodeproj/project.pbxproj: add new chanio.test.
	* macosx/Tcl.xcode/project.pbxproj:

2007-11-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompile.c (TclCompileScript): Ensure that we get our count
	in our INST_START_CMD calls right, even when there's a failure 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 flag
	* generic/tclExecute.c:		bit INTERP_RESULT_UNCLEAN: shortcut for
	* generic/tclInt.h:		Tcl_ResetResult for the "normal" case:
	* generic/tclProc.c:		TCL_OK, no return options, no errorCode
	* generic/tclResult.c:		nor errorInfo, return at normal level.
	* generic/tclStubLib.c:		[Patch 1830184]
	* generic/tclUtil.c:

	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>

	* generic/tclCompCmds.c, generic/tclCompile.c, generic/tclCompile.h:
	* generic/tclExecute.c, generic/tclInt.decls, generic/tclIntDecls.h:
	* generic/tclRegexp.c, generic/tclRegexp.h: Add INST_REGEXP and fully
	* generic/tclStubInit.c, generic/tclUtil.c: compiled [regexp] for the
	* tests/regexpComp.test:     [Bug 1830166]  simple cases. Also added
	TclReToGlob function to convert RE to glob patterns and use these in
	the possible cases.

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

	* generic/tclResult.c (ResetObjResult): clarify the logic.

	* generic/tclBasic.c:		Increased usage of macros to detect
	* generic/tclBinary.c:		and take advantage of objTypes. Added
	* generic/tclClock.c:		macros TclGet(Int|Long)FromObj,
	* generic/tclCmdAH.c:		TclGetIntForIndexM & TclListObjLength,
	* generic/tclCmdIL.c:		modified TclListObjGetElements.

	* generic/tclDictObj.c:		their functionality to other cases.
	* generic/tclExecute.c:
	* generic/tclGet.c:		As this patch touches many files it has
	* generic/tclIO.c:		been recorded as [Patch 1830038] in

	* unix/tclUnixTime.c (TclpWideClicksToNanoseconds): Fix issues with
	* generic/tclInt.h:				    int64_t overflow.

	* generic/tclBasic.c:	Fix stack check failure case if stack grows up
	* unix/tclUnixInit.c:	Simplify non-crosscompiled case.

	* unix/configure:	autoconf-2.59
	* unix/tclConfig.h.in:	autoheader-2.59

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

	not a list.

	* generic/tclBasic.c:
	* unix/configure.in:
	* unix/tclUnixInit.c: Detect stack grwoth direction at compile time,

	* 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.

	* 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>

	replace Tcl_AsyncReady and TclpCheckStackSpace by much faster variants.
	[Patch 1829248]

	don't allow a nocase option. [Bug 1828296]
	For INST_STR_MATCH, ignore pattern type for TclByteArrayMatch case.

							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):
	* generic/tclVar.c (TclObjLookupVarEx):

	like array element (code not normally exercised).

2007-11-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tools/tcltk-man2html.tcl (output-directive): Convert .DS/.DE pairs
	into tables since that is now all that they are used for.

	* doc/RegExp.3: Clarified documentation of RE flags. [Bug 1167840]

	* doc/refchan.n: Adjust internal name to be consistent with the file
	name for reduced user confusion. After comment by Dan Steffen.

	* generic/tclCmdMZ.c (Tcl_StringObjCmd, UniCharIsAscii): Remember, the
	NUL character is in ASCII too. [Bug 1808258]

	* doc/file.n: Clarified use of [file normalize]. [Bug 1185154]

2007-10-30  Don Porter	<dgp@users.sourceforge.net>

	subcommands so Solaris nroff doesn't truncate them. [Bug 1822268]

2007-10-30  Donal K. Fellows  <dkf@users.sf.net>

	* tools/tcltk-man2html.tcl (output-widget-options): Enhance the HTML

2007-10-28  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclUtil.c (Tcl_ConcatObj): optimise for some of the
	concatenees being empty objs. [Bug 1447328]

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
	mapping functions.

2007-10-27  Donal K. Fellows  <dkf@users.sf.net>

	* generic/regc_lex.c (lexescape): Close off one of the problems

	* generic/tclCompile.h:
	* generic/tclInt.h: moved declaration of TclSetCmdNameObj from
	tclCompile.h to tclInt.h, reverting linker [Bug 1821159] caused by
	commit of 2007-10-11 (both I and gcc missed one dep).

	* generic/tclVar.c: try to preserve Tcl_Objs when doing variable
	lookups by name, partially addressing [Bug 1793601].

2007-10-27  Donal K. Fellows  <dkf@users.sf.net>

	* tools/tcltk-man2html.tcl (make-man-pages, htmlize-text)

	* generic/tclThread.c: Added TclpMasterLock/Unlock arround calls to
	ForgetSyncObject in Tcl_MutexFinalize and Tcl_ConditionFinalize to
	prevent from garbling the internal lists that track sync objects. [Bug

	fundamental datatype assumptions and causing a stack crash when the
	dict was converted to a string. [Bug 1786481]

2007-09-07  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclEvent.c ([::tcl::Bgerror]):	Corrections to Tcl's

	* 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
	* generic/tclIO.c:	TclBackgroundException().
	* generic/tclIOCmd.c:
	* generic/tclTimer.c:

	* generic/tclIntDecls.h:	make genstubs
	* generic/tclStubInit.c:

2007-09-06  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.xcode/project.pbxproj: discontinue unmaintained support
	* macosx/Tcl.xcode/default.pbxuser: for Xcode 1.5; replace by Xcode2
	project for use on Tiger (with Tcl.xcodeproj to be used on Leopard).

	* macosx/Tcl.xcodeproj/project.pbxproj: updates for Xcode 2.5 and 3.0.
	* macosx/Tcl.xcodeproj/default.pbxuser:
	* macosx/Tcl.xcode/project.pbxproj:
	* macosx/Tcl.xcode/default.pbxuser:
	* macosx/Tcl-Common.xcconfig:

	* macosx/README: document project changes.

2007-09-05  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Removed support for the unmaintained
	* generic/tclExecute.c: -DTCL_GENERIC_ONLY configuration. [Bug
	* unix/Makefile.in:	1264623]

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
	Makefile remember the dependency for us.

	* unix/Makefile.in:	Corrections to `make dist` dependencies to be
	sure that macosx/configure gets generated whenever it does not exist.

2007-09-03  Kevin B, Kenny  <kennykb@acm.org>

	* generic/tclListObj.c (TclLindexFlat):
	* tests/lindex.test (lindex-17.[01]):	Added code to detect the error
	when a script does [lindex {} end foo]; an overaggressive optimisation
	caused this call to return an empty object rather than an error.

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

	* generic/tclObj.c (TclInitObjSubsystem): restore registration of the
	"wideInt" Tcl_ObjType for compatibility with 8.4 extensions that
	access the tclWideIntType Tcl_ObjType; add setFromAnyProc for
	tclWideIntType.

2007-09-02  Donal K. Fellows  <dkf@users.sf.net>

	* doc/lsearch.n: Added note that order of results with the -all option
	is that of the input list. It always was, but this makes it crystal.

2007-08-30  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompile.c: Added fflush() calls following all callers of
	* generic/tclExecute.c: TclPrintByteCodeObj() so that tcl_traceCompile
	output is less likely to get mangled when writes to stdout interleave
	with other code.

2007-08-28  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Use a table lookup in ParseLexeme() to
	determine lexemes with single-byte representations.

	* generic/tclBasic.c:	Used unions to better clarify overloading of
	* generic/tclCompExpr.c:	the fields of the OpCmdInfo and
	* generic/tclCompile.h:		TclOpCmdClientData structs.

2007-08-27  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Call TclCompileSyntaxError() when
	expression syntax errors are found when compiling expressions. With
	this in place, convert TclCompileExpr to return void, since there's no
	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
	over some issues with that (ab)use. New routine produces a new opcode
	INST_SYNTAX, which is a minor variation of INST_RETURN_IMM. Also a bit
	of constification.

	* generic/tclCompile.c: Move the deallocation of local LiteralTable
	* generic/tclCompExpr.c:	entries into TclFreeCompileEnv().
	* generic/tclExecute.c: Update callers.

	* generic/tclCompExpr.c:	Force numeric and boolean literals in
	expressions to register with their intreps intact, even if that means
	overwriting existing intreps in already registered literals.

2007-08-25  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclExecute.c (TclExecuteByteCode): Added code to handle
	* tests/expr.test (expr-23.48-53)	     integer exponentiation
	that results in 32- and 64-bit integer results, avoiding calls to wide
	integer exponentiation routines in this common case. [Bug 1767293]

	* library/clock.tcl (ParseClockScanFormat): Modified code to allow
	* tests/clock.test (clock-60.*):	    case-insensitive matching
	of time zone and month names. [Bug 1781282]

2007-08-24  Don Porter	<dgp@users.sourceforge.net>

	* 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
	INSTs for debug builds. REVERTED (collision with alternative fix)

2007-08-21  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclMain.c:	Corrected the logic of dropping the last
	* tests/main.test:	newline from an interactively typed command.
	[Bug 1775878]

2007-08-21  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* tests/thread.test: thread-4.4: clear ::errorInfo in the thread as a
	message is left here from init.tcl on windows due to no tcl_pkgPath.

2007-08-20  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (INST_SUB): fix usage of the new macro for
	overflow detection in sums, adapt to subtraction. Lengthy comment
	added.

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))
	now
	  (((a^s) >= 0) || ((a^b) < 0))
	This expresses: "a and s have the same sign or else a and b have
	different sign".

2007-08-19  Donal K. Fellows  <dkf@users.sf.net>

	* doc/interp.n (RESOURCE LIMITS): Added text to better explain why
	time limits are described using absolute times. [Bug 1752148]

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
	comparisons to verify that the cached value is usable.

	* 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].

2007-08-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclIOUtil.c (TclGetOpenModeEx): Only set the O_APPEND flag
	* tests/ioUtil.test (ioUtil-4.1):	  on a channel for the 'a'
	mode and not for 'a+'. [Bug 1773127]

2007-08-14  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (INST_INVOKE*): peephole opt, do not get the
	interp's result if it will be pushed/popped.

2007-08-14  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Use fully qualified variable names for
	* tests/thread.test:	::errorInfo and ::errorCode so that string
	* tests/trace.test:	reported to variable traces are fully
	qualified in agreement with Tcl 8.4 operations.

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

	* unix/tclLoadDyld.c: use dlfcn API on Mac OS X 10.4 and later; fix
	issues with loading from memory on intel and 64bit; add debug messages

	* tests/load.test: add test load-10.1 for loading from vfs.

	* unix/dltest/pkga.c:		whitespace & comment cleanup, remove

	* generic/tclExecute.c: Provide DECACHE/CACHE protection to the
	* tests/trace.test:	Tcl_LogCommandInfo() call. [Bug 1773040]

2007-08-12  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCmdMZ.c (Tcl_SplitObjCmd): use TclNewStringObj macro
	instead of calling the function.

	* generic/tcl_Obj.c (TclAllocateFreeObjects): remove unneeded memset
	to 0 of all allocated objects.

2007-08-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.h: remove redundant ops in TclNewStringObj macro.

2007-08-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.h: fix the TclSetVarNamespaceVar macro, was causing a
	leak.

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.

2007-08-09  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclProc.c (TclCreateProc): better comments on the required
	varflag values when loading precompiled procs.

	* generic/tclExecute.c (INST_STORE_ARRAY):
	* tests/trace.test (trace-2.6): whole array write traces on compiled
	local variables were not firing. [Bug 1770591]

2007-08-08  Jeff Hobbs	<jeffh@ActiveState.com>

	* generic/tclProc.c (InitLocalCache): reference firstLocalPtr via
	procPtr. codePtr->procPtr == NULL exposed by tbcload.

2007-08-08  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c: Corrected failure to compile/link in the
	-DNO_WIDE_TYPE configuration.

	* generic/tclExecute.c: Corrected improper use of bignum arguments to
	* tests/expr.test:	*SHIFT operations. [Bug 1770224]

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.

	* generic/tclInt.decls:	  Exporting via stubs to help xotcl adapt to
	* generic/tclInt.h:	  VarReform.
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c:

2007-08-07  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclEnv.c:	improve environ handling on Mac OS X (adapted
	* unix/tclUnixPort.h:	from Apple changes in Darwin tcl-64).

	* 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;
	support overriding TCL_PACKAGE_PATH/TCL_MODULE_PATH in environment.

	* unix/configure: autoconf-2.59

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
				silence compiler warnings.
	* generic/tclDate.c:	Regenerated
	* win/tclWinTest.c:	Added a cast to GetSecurityDescriptorDacl call
				to silence compiler warnings.

2007-08-04  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.decls:	  Exporting via stubs to help itcl adapt to
	* generic/tclInt.h:	  VarReform. Added localCache initialization
	* generic/tclIntDecls.h:  to TclInitCompiledLocals (which only exists
	* generic/tclProc.c:	  for itcl).
	* generic/tclStubInit.c:
	* generic/tclVar.c:

2007-08-01  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* library/word.tcl: Rewrote for greater efficiency. [Bug 1764318]

2007-08-01  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* generic/tclInt.h:	Added a TclOffset macro ala Tk_Offset to
	* generic/tclVar.c:	abstract out 'offsetof' which may not be
	* generic/tclExceute.c: defined (eg: msvc6).

2007-08-01  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (TclCleanupVar): fix [Bug 1765225], thx Larry
	Virden.

2007-07-31  Miguel Sofer  <msofer@users.sf.net>

	* doc/Hash.3:
	* generic/tclHash.c:
	* generic/tclObj.c:
	* generic/tclThreadStorage.c: (changes part of the patch below)
	Stop Tcl_CreateHashVar from resetting hPtr->clientData to NULL after
	calling the allocEntryProc for a custom table.

	* generic/tcl.h:
	* generic/tclBasic.c:
	* generic/tclCmdIL.c:

	* generic/tclObj.c:
	* generic/tclProc.c:
	* generic/tclThreadStorage.c:
	* generic/tclTrace.c:
	* generic/tclVar.c: VarReform [Patch 1750051]

	*** 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>

	* unix/configure.in: allow use of 'inline' in Tcl sources. [Patch
	* win/configure.in:  1754128]
	* win/makefile.vc:   Regen with autoconf 2.61

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

	* unix/tclUnixInit.c (TclpSetVariables): Use the thread-safe getpwuid
	replacement to fill the tcl_platform(user) field as it is not subject
	to spoofing. [Bug 681877]

	* unix/tclUnixCompat.c: Simplify the #ifdef logic.

	* unix/tclUnixChan.c (FileWatchProc): Fix test failures.

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]

2007-07-05  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclNamesp.c (SetNsNameFromAny):
	* generic/tclObj.c (SetCmdNameFromAny): Avoid unnecessary
	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
	* generic/tclObj.c:    in a different interp, tkcon. [Bug 1747512]

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
	* generic/tclInt.h:	routine TclFinalizeCompilation().

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

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Plug a memory leak caused by a

2007-06-30  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* generic/tclThread.c: Prevent RemeberSyncObj() from growing the sync
	object lists by reusing already free'd slots, if possible. See
	discussion on Bug 1726873 for more information.

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

	function to make it clearer how to use it. [Bug 1710795]

2007-06-29  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclAlloc.c:		on Darwin, ensure memory allocated by
	* generic/tclThreadAlloc.c:	the custom TclpAlloc()s is aligned to
	16 byte boundaries (as is the case with the Darwin system malloc).

	* generic/tclGetDate.y: use ckalloc/ckfree instead of malloc/free.
	* generic/tclDate.c:	bison 1.875e

	* generic/tclBasic.c (TclEvalEx): fix warnings.

	* macosx/Tcl.xcodeproj/project.pbxproj: better support for renamed tcl

	* tests/trace.test:	when multiple Tcl_CreateTrace traces were set
	and one of them did not fire due to level restrictions. [Bug 1743931]

2007-06-26  Don Porter	<dgp@users.sourceforge.net>

	stack to the Tcl stack.

2007-06-26  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (UnsetVarStruct): more streamlining.

2007-06-25  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c: Safety checks to avoid crashes in the
	TclStack* routines when called with an incompletely initialized
	interp. [Bug 1743302]

2007-06-25  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (UnsetVarStruct): fixing incomplete change, more
	streamlining.

2007-06-24  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (TclDeleteCompiledLocalVars): removed inlining that
	ended up not really optimising (limited benchmarks). Now calling
	UnsetVarStruct (streamlined old code is #ifdef'ed out, in case better
	benchmarks do show a difference).

	* generic/tclVar.c (UnsetVarStruct): fixed a leak introduced in last
	commit.

2007-06-23  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (UnsetVarStruct, TclDeleteVars): made the logic
	slightly clearer, eliminated some duplicated code.

	*** POTENTIAL INCOMPATIBILITY *** (tclInt.h and Var struct users)
	The core never builds VAR_LINK variable to have traces. Such a
	"monster", should one exist, will now have its unset traces called
	*before* it is unlinked.

2007-06-23  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/tclMacOSXNotify.c (AtForkChild): don't call CoreFoundation
	APIs after fork() on systems where that would lead to an abort().

2007-06-22  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c: Revised TclStackRealloc() signature to better
	* generic/tclInt.h:	parallel (and fall back on) Tcl_Realloc.

	* generic/tclNamesp.c (TclResetShadowesCmdRefs):	Replaced
	ckrealloc based allocations with TclStackRealloc allocations.

	* generic/tclCmdIL.c:	More conversions to use TclStackAlloc.
	* generic/tclScan.c:

2007-06-21  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	 Move most instances of the Tcl_Parse struct
	* generic/tclCompExpr.c: off the C stack and onto the Tcl stack. This
	* generic/tclCompile.c:	 is a rather large struct (> 3kB).
	* generic/tclParse.c:

2007-06-21  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c (TEOvI):		Made sure that leave traces
	* generic/tclExecute.c (INST_INVOKE):	that were created during
	* tests/trace.test (trace-36.2):	execution of an originally
	untraced command do not fire [Bug 1740962], partial fix.

2007-06-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tcl.h, generic/tclCompile.h, generic/tclCompile.c: Remove
	references in comments to obsolete {expand} notation. [Bug 1740859]

2007-06-20  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c: streamline namespace vars deletion: only compute
	the variable's full name if the variable is traced.

2007-06-20  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclInt.decls: Revised the interfaces of the routines
	* generic/tclExecute.c: TclStackAlloc and TclStackFree to make them
	easier for callers to use (or more precisely, harder to misuse).
	TclStackFree now takes a (void *) argument which is the pointer
	intended to be freed. TclStackFree will panic if that's not actually
	the memory the call will free. TSA/TSF also now tolerate receiving
	(interp == NULL), in which case they simply fall back to be calls to
	Tcl_Alloc/Tcl_Free.

	* generic/tclIntDecls.h:	make genstubs

	* generic/tclBasic.c:	Updated callers

	standardized headers, subheaders, dictionary sorting of names.

2007-06-18  Jeff Hobbs	<jeffh@ActiveState.com>

	* tools/tcltk-man2html.tcl: clean up copyright merging and output.
	clean up coding constructs.

2007-06-18  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCmdIL.c (InfoFrameCmd):
	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd):
	* generic/tclCompile.c (TclInitCompileEnv):
	* generic/tclProc.c (Tcl_ProcObjCmd, SetLambdaFromAny): Moved the
	CmdFrame off the C stack and onto the Tcl stack.

	* generic/tclExecute.c (TEBC):	Moved the CmdFrame off the C stack and
	onto the Tcl stack, between the catch and the execution stacks

2007-06-18  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c (TclEvalEx,TclEvalObjEx):	Moved the CmdFrame off
	the C stack and onto the Tcl stack.

2007-06-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclProc.c (TclObjInterpProcCore): Minor fixes to make
	* generic/tclExecute.c (TclExecuteByteCode): compilation debugging
	builds work again. [Bug 1738542]

2007-06-16  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclProc.c (TclObjInterpProcCore): Use switch instead of a
	chain of if's for a modest performance gain and a little more clarity.

2007-06-15  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompCmds.c:  Simplified [variable] compiler and executor.
	* generic/tclExecute.c:	  Missed updates to "there is always a valid
	frame".

	* generic/tclCompile.c: reverted TclEvalObjvInternal and INST_INVOKE
	* generic/tclExecute.c: to essentially what they were previous to the
	* generic/tclBasic.c:	commit of 2007-04-03 [Patch 1693802] and the
	subsequent optimisations, as they break the new trace tests described
	below.

	* generic/trace.test: added tests 36 to 38 for dynamic trace creation
	and addition. These tests expose a change in dynamics due to a recent
	round of optimisations. The "correct" behaviour is not described in
	docs nor TIP 62.

2007-06-14  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.decls:	  Modif to the internals of TclObjInterpProc
	* generic/tclInt.h:	  to reduce stack consumption and improve task
	* generic/tclIntDecls.h:  separation. Changes the interface of
	* generic/tclProc.c:	  TclObjInterpProcCore (patching TclOO
	simultaneously).

	* generic/tclProc.c (TclObjInterpProcCore): simplified obj management
	in wrongNumArgs calls.

2007-06-14  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompile.c: SetByteCodeFromAny() can no longer return any
	* generic/tclExecute.c: code other than TCL_OK, so remove code that
	* generic/tclProc.c:	formerly handled exceptional codes.

2007-06-13  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (TclCompEvalObj): missed update to "there is
	always a valid frame".

	* generic/tclProc.c (TclObjInterpProcCore): call TEBC directly instead
	of going through TclCompEvalObj - no need to check the compilation's
	freshness, this has already been done. This improves speed and should
	also provide some relief to [Bug 1066755].

2007-06-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclBasic.c (Tcl_CreateInterp): Turn the [info] command into
	* generic/tclCmdIL.c (TclInitInfoCmd):	 an ensemble, making it easier
	for third-party code to plug into.

	* generic/tclIndexObj.c (Tcl_WrongNumArgs):
	* generic/tclNamesp.c, generic/tclInt.h (tclEnsembleCmdType): Make
	Tcl_WrongNumArgs do replacement correctly with ensembles and other
	sorts of complex replacement strategies.

2007-06-11  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c:	 comments added to explain iPtr->numLevels
	management.

	* generic/tclNamesp.c:	 tweaks to Tcl_GetCommandFromObj and
	* generic/tclObj.c:	 TclGetNamespaceFromObj; modified the usage of
	structs ResolvedCmdName and ResolvedNsname so that the field refNsPtr
	is NULL for fully qualified names.

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

	* generic/tclBasic.c:	 Further TEOvI split, creating a new
	* generic/tclCompile.h:	 TclEvalObjvKnownCommand() function to handle
	* generic/tclExecute.c:	 commands that are already known and are not
	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
	between compiled and non-compiled code.
	***THIS CHANGE IS UNDER REVIEW***

2007-06-10  Jeff Hobbs	<jeffh@ActiveState.com>

	* README: updated links. [Bug 1715081]

	* generic/tclExecute.c (TclExecuteByteCode): restore support for
	INST_CALL_BUILTIN_FUNC1 and INST_CALL_FUNC1 bytecodes to support 8.4-
	precompiled sources (math functions). [Bug 1720895]

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

	* generic/tclInt.h:
	* generic/tclNamesp.c:
	* generic/tclObj.c:
	* generic/tclvar.c: new macros TclGetCurrentNamespace() and
	TclGetGlobalNamespace(); Tcl_GetCommandFromObj and
	TclGetNamespaceFromObj rewritten to make the logic clearer; slightly
	faster too.

2007-06-09  Miguel Sofer  <msofer@users.sf.net>

	* 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:
	* generic/tclInterp.c:

	* generic/tclInt.h:	New TclCleanupCommandMacro for core usage.
	* generic/tclBasic.c:
	* generic/tclExecute.c:
	* generic/tclObj.c:

2007-06-09 Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.xcodeproj/project.pbxproj: add new Tclsh-Info.plist.in.

2007-06-08  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Changed [string first] and
	* doc/string.n: [string last] so that they have clearer descriptions
	for those people who know the adage about needles and haystacks. This
	follows suggestions on comp.lang.tcl...

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

	* generic/tclBasic.c:	Added interp flag value ERR_LEGACY_COPY to

	* generic/tclNamesp.c:	variables ::errorCode and ::errorInfo get
	* generic/tclProc.c:	updated after an error. This keeps more
	* generic/tclResult.c:	precise compatibility with Tcl 8.4.

	* unix/Makefile.in: add datarootdir to silence autoconf-2.6x warning.

2007-05-30  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Removed code that dealt with
	* generic/tclCompile.c: TCL_TOKEN_EXPAND_WORD tokens representing
	* generic/tclCompile.h: expanded literal words. These sections were
	mostly in place to enable [info frame] to discover line information in
	expanded literals. Since the parser now generates a token for each
	post-expansion word referring to the right location in the original
	script string, [info frame] gets all the data it needs.

	* generic/tclInt.h:	Revised the parser so that it never produces
	* generic/tclParse.c:	TCL_TOKEN_EXPAND_WORD tokens when parsing an
	* tests/parse.test:	expanded literal word; that is, something like
	{*}{x y z}. Instead, generate the series of TCL_TOKEN_SIMPLE_WORD
	tokens to represent the words that expansion of the literal string
	produces. [RFE 1725186]

2007-05-29  Jeff Hobbs	<jeffh@ActiveState.com>

	* unix/tclUnixThrd.c (Tcl_JoinThread): fix for 64-bit handling of

2007-05-07  Don Porter	<dgp@users.sourceforge.net>

	[Tcl Bug 1706140]

	* generic/tclLink.c (LinkTraceProc):	Update Tcl_VarTraceProcs so
	* generic/tclNamesp.c (Error*Read):	they call Tcl_InterpDeleted()
	* generic/tclTrace.c (Trace*Proc):	for themselves, and do not
	* generic/tclUtil.c (TclPrecTraceProc): rely on (frequently buggy)
	setting of the TCL_INTERP_DESTROYED flag by the trace core.

	* generic/tclVar.c:	Update callers of TclCallVarTraces to not pass
	in the TCL_INTERP_DESTROYED flag. Also apply filters so that public
	routines only pass documented flag values down to lower level routines

	* generic/tclTrace.c (TclCallVarTraces):	The setting of the
	TCL_INTERP_DESTROYED flag is now done entirely within the
	TclCallVarTraces routine, the only place it can be done right.

2007-05-06  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclInt.h (ExtraFrameInfo): Create a new mechanism for

	* generic/tclIO.c (TclFinalizeIOSubsystem): Added an initializer to
	silence a spurious gcc warning about use of an uninitialized
	variable.
	* tests/encoding.test: Modified so that encoding tests happen in a
	private namespace, to avoid polluting the global one. This problem was
	discovered when running the test suite '-singleproc 1 -skip exec.test'
	because the 'path' variable in encoding.test conflicted with the one
	in io.test.

	imbalance that affected the filesystem-[147]* tests in the test suite.
	Thanks to Don Porter for the patch. [Bug 1710707]
	* generic/tclPathObj.c (Tcl_FSJoinPath, Tcl_FSGetNormalizedPath):

	patch.

2007-05-01  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (TclPtrSetVar): fixed leak whenever newvaluePtr had
	refCount 0 and was used for appending (but not lappending). Thanks to
	mistachkin and kbk. [Bug 1710710]

2007-05-01  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclIO.c (DeleteChannelTable): Made changes so that
	DeleteChannelTable tries to close all open channels, not just the
	first. [Bug 1710285]
	* generic/tclThread.c (TclFinalizeSynchronization): Make sure that TSD
	blocks get freed on non-threaded builds. [Bug 1710825]
	* tests/utf.test (utf-25.1--utf-25.4): Modified tests to clean up
	after the 'testobj' extension to avoid spurious reports of memory
	leaks.

2007-05-01  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c (STR_MAP): When [string map] has a pure dict map,
	a missing Tcl_DictObjDone() call led to a memleak. [Bug 1710709]

2007-04-30  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in: add 'tclsh' dependency to install targets that
	rely on tclsh, fixes parallel 'make install' from empty build dir.

2007-04-30  Andreas Kupries <andreask@gactivestate.com>

	* generic/tclIO.c (FixLevelCode): Corrected reference count
	mismanagement of newlevel, newcode. Changed to allocate the Tcl_Obj's
	as late as possible, and only when actually needed. [Bug 1705778, leak
	K29]

2007-04-30  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclProc.c (Tcl_ProcObjCmd, SetLambdaFromAny): Corrected

	error message generation when associated with argument names that are
	really used. [Bug 1705778, leak K15]

2007-04-25  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclIOUtil.c (Tcl_FSChdir): Changed the memory management so
	that the path returned from Tcl_FSGetNativePath is not duplicated
	before being stored as the current directory, to avoid a memory leak.
	[Bug 1705778, leak K01 among other manifestations]

2007-04-25  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c (ParseExpr):	Revised to be sure that an
	error return doesn't prevent all literals getting placed on the
	litList to be returned to the caller for freeing. Corrects some
	memleaks. [Bug 1705778, leak K23]

2007-04-25  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in (dist): add macosx/*.xcconfig files to src dist;

2007-04-24  Miguel Sofer  <msofer@users.sf.net>

	* 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
	internal representation of a dict is only set when necessary. [Bug
	1705778, leak K04]
	(DictFilterCmd): Added code to drop the lock in the trivial match
	case. [Bug 1705778, leak K05]

2007-04-24  Kevin B. Kenny  <kennykb@acm.org>

	* 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>

	* generic/tclCompExpr.c (ParseExpr): Memory leak in error case; the
	literal Tcl_Obj was not getting freed. [Bug 1705778, leak #1 (new)]

	* generic/tclNamesp.c (Tcl_DeleteNamespace):	Corrected flaw in the
	flag marking scheme to be sure that global namespaces are freed when
	their interp is deleted. [Bug 1705778]

2007-04-24  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclExecute.c (TclExecuteByteCode): Plugged six memory leaks
	in bignum arithmetic.

	object if the physical read returned an error and the bypass area had
	no message.
	* generic/tclIORChan.c (TclChanCreateObjCmd): Plugged a leak of the
	return value from the "initialize" method of a channel handler.
	(All of the above under [Bug 1705778])

	* macosx/Tcl-Common.xcconfig: enable more warnings.

	* macosx/Tcl.xcodeproj/project.pbxproj: add 'DebugMemCompile' build
	configuration that calls configure with --enable-symbols=all; override
	configure check for __attribute__((__visibility__("hidden"))) in Debug
	configuration to restore availability of ZeroLink.

	* macosx/tclMacOSXNotify.c: fix warnings.

2007-04-23  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompile.c (TclFreeCompileEnv): Tip 280's new field
	extCmdMapPtr was not being freed. [Bug 1705778, leak #1]

2007-04-23  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclCompCmds.c (TclCompileUpvarCmd): Plugged a memory leak in
	'upvar' when compiling (a) upvar outside a proc, (b) upvar with a
	syntax error, or (c) upvar where the frame index is not known at
	compile time.
	* generic/tclCompExpr.c (ParseExpr): Plugged a memory leak when
	parsing expressions that contain syntax errors.
	* generic/tclEnv.c (ReplaceString): Clear memory correctly when
	growing the cache to avoid reads of uninitialised data.
	* generic/tclIORChan.c (TclChanCreateObjCmd, FreeReflectedChannel):
	Plugged two memory leaks.
	* generic/tclStrToD.c (AccumulateDecimalDigit): Fixed a mistake where
	we'd run beyond the end of the 'pow10_wide' array if a number begins
	with a string of more than 'maxpow10_wide' zeroes.
	* 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

	called after freeing root CallFrame (on interp deletion).

2007-04-20  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclListObj.c (SetListFromAny): avoid discarding internal
	reps of objects converted to singleton lists. [Patch 738900]

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
	Japanese locale (most notably, incorrect dates for the Emperors'
	eras). [Bug 1637471]. Many thanks to SourceForge user 'nyademo' for
	pointing this out and developing a fix.
	* 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
	military NZA time zones had the signs reversed. [Bug 1586828]
	* generic/tclDate.c: Regenerated.
	* doc/Notifier.3: Documented Tcl_SetNotifier and Tcl_ServiceModeHook.
	Quite against my better judgment. [Bug 414933]

	* generic/tclResult.c, generic/tclTest.c, generic/tclTestObj.c:
	* generic/tclVar.c, unix/tclUnixChan.c, unix/tclUnixTest.c:
	* win/tclWinLoad.c, win/tclWinSerial.c: Replaced commas in varargs
	with string concatenation where possible. [Patch 1515234]
	* library/tzdata/America/Tegucigalpa:
	* library/tzdata/Asia/Damascus: Olson's tzdata 2007e.

2007-04-19  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/regcomp.c, generic/regc_cvec.c, generic/regc_lex.c,
	* generic/regc_locale.c: Improve the const-correctness of the RE
	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>

	* library/clock.tcl: Fixed the naming of
	::tcl::clock::ReadZoneinfoFile because (yoicks!) it was in the global
	namespace.
	* doc/clock.n: Clarified the cases in which legacy time zone is
	recognized. [Bug 1656002]

2007-04-17  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: fixed checkInterp logic [Bug 1702212]

2007-04-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	function definitions from manually-written code.

2007-04-15  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclCompCmds.c: added a cast to silence a compiler error on
	VC2005.
	* library/clock.tcl: Restored unique-prefix matching of keywords on
	the [clock] command. [Bug 1690041]
	* tests/clock.test: Added rudimentary test cases for unique-prefix
	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
	tosPtr from TEBC (after initialisation and the code at the label
	cleanupV_pushObjResultPtr).

2007-04-11  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompCmds.c: moved all exceptDepth management to the
	macros - the decreasing half was managed by hand.

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>

	* generic/tclCompile (tclInstructionTable): Fixed bugs in description
	of dict instructions.

2007-04-07  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompile (tclInstructionTable): Fixed bug in description
	of INST_START_COMMAND.

	* generic/tclExecute.c (TEBC): Small code reduction.

2007-04-06  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (TEBC):
	* generic/tclNamespace.c (NsEnsembleImplementationCmd):
	* generic/tclProc.c (InitCompiledLocals, ObjInterpProcEx)
	(TclObjInterpProcCore, ProcCompileProc): Code reordering to reduce
	branching and improve branch prediction (assume that forward branches
	are typically not taken).

2007-04-03  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: INST_INVOKE optimisation. [Patch 1693802]

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

	* generic/tclNamesp.c:	Revised ErrorCodeRead and ErrorInfoRead trace
	routines so they guarantee the ::errorCode and ::errorInfo variable
	always appear to exist. [Bug 1693252]

2007-04-03  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.decls:	 Moved TclGetNamespaceFromObj() to the
	* generic/tclInt.h:	 internal stubs table; regen.
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c:

2007-04-02  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:	  Added bytecode compilers for the variable
	* generic/tclCompCmds.c:  linking commands: 'global', 'variable',
	* generic/tclCompile.h:	  'upvar', 'namespace upvar' [Patch 1688593]
	* generic/tclExecute.c:
	* generic/tclInt.h:
	* generic/tclVar.c:

2007-04-02  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Replace arrays on the C stack and ckalloc
	* generic/tclExecute.c: calls with TclStackAlloc calls to use memory
	* generic/tclFCmd.c:	on Tcl's evaluation stack.
	* generic/tclFileName.c:
	* generic/tclIOCmd.c:
	* generic/tclIndexObj.c:
	* generic/tclInterp.c:

	* generic/tclTrace.c:
	* unix/tclUnixPipe.c:

2007-04-01  Donal K. Fellows  <dkf@users.sf.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/tclCompCmds.c:	Replace arrays on the C stack and
	ckalloc calls with TclStackAlloc calls to use memory on Tcl's
	evaluation stack.

	* generic/tclCmdMZ.c:	Revised [string to* $s $first $last]
	implementation to reduce number of allocs/copies.

	* tests/string.test:  More [string reverse] tests.

2007-03-30  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: optimise the lookup of elements of indexed
	arrays.

2007-03-29  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclProc.c (Tcl_ApplyObjCmd):
	* tests/apply.test (9.3): Fixed Tcl_Obj leak on error return; an
	unneeded ref to lambdaPtr was being set and not released on an error
	return path.

2007-03-28  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c (STR_REVERSE):	Implement the actual [string
	reverse] command in terms of the new TclStringObjReverse() routine.

	* generic/tclInt.h (TclStringObjReverse):	New internal routine
	* generic/tclStringObj.c (TclStringObjReverse): that implements the
	[string reverse] operation, making use of knowledge/surgery of the
	String intrep to minimize the number of allocs and copies needed to do
	the job.

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

	* generic/tclCmdMZ.c (STR_MAP): Replace ckalloc calls with
	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>

	* generic/tclBasic.c (DeleteInterpProc): pop the root frame pointer
	before deleting the global namespace [Bug 1658572]

2007-03-23  Kevin B. Kenny  <kennykb@acm.org>

	* win/Makefile.in: Added code to keep a Cygwin path name from leaking
	into LIBRARY_DIR when doing 'make test' or 'make runtest'.

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/tclExecute.c: More ckalloc -> ckrealloc conversions.
	* generic/tclLiteral.c:
	* generic/tclNamesp.c:
	* generic/tclParse.c:
	* generic/tclPreserve.c:
	* generic/tclStringObj.c:

	* generic/tclLink.c:

2007-03-20  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclDate.c: Rebuilt, despite Donal Fellows's comment when
	committing it that no rebuild was required.
	* generic/tclGetDate.y: According to Donal Fellows, "Introduce modern
	formatting standards; no need for rebuild of tclDate.c."

	* generic/tclListObj.c (TclLsetList, TclLsetFlat):
	* tests/lset.test: Changes to deal with shared internal representation
	for lists passed to the [lset] command. Thanks to Don Porter for
	fixing this issue. [Bug 1677512]

2007-03-19  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompile.c: Revise the various expansion routines for
	CompileEnv fields to use ckrealloc() where appropriate.

	* generic/tclBinary.c (Tcl_SetByteArrayLength): Replaced ckalloc() /
	memcpy() sequence with ckrealloc() call.

	* generic/tclBasic.c (Tcl_CreateMathFunc):	Replaced some calls to

	* unix/tclUnixTime.c (SetTZIfNecessary):	better supports memory
	* win/tclAppInit.c (setargv):			debugging.

2007-03-19  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* doc/regsub.n: Corrected example so that it doesn't recommend
	potentially unsafe practice. Many thanks to Konstantin Kushnir
	<chpock@gmail.com> for reporting this.

2007-03-17  Kevin B. Kenny  <kennykb@acm.org>

	* win/tclWinReg.c (GetKeyNames): Size the buffer for enumerating key
	names correctly, so that Unicode names exceeding 127 chars can be
	retrieved without crashing. [Bug 1682211]
	* tests/registry.test (registry-4.9): Added test case for the above
	bug.

2007-03-15  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIOUtil.c (Tcl_Stat): Reimplement workaround to avoid gcc
	warning by using local variables. When the macro argument is of type
	long long instead of long, the incorrect warning is not generated.

2007-03-15  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/Makefile.in: Fully qualify LIBRARY_DIR so that `make test` does
	not depend on working dir.

	variables so that shimmering of that list doesn't lead to invalid
	pointers. [Bug 1671087]

	* generic/tclEvent.c (HandleBgErrors):	Make efficient private copy
	* tests/event.test (event-5.3): of the command prefix for the interp's
	background error handling command to avoid panics due to pointers to
	memory invalid after shimmering. [Bug 1670155]

	* generic/tclNamesp.c (NsEnsembleImplementationCmd):	Make efficient
	* tests/namespace.test (namespace-42.8):	private copy of the
	command prefix as we invoke the command appropriate to a particular
	subcommand of a particular ensemble to avoid panic due to shimmering
	of the List intrep. [Bug 1670091]

	* generic/tclVar.c (TclArraySet):	Make efficient private copy of
	* tests/var.test (var-17.1):	the "list" argument to [array set] to
	avoid crash due to shimmering invalidating pointers. [Bug 1669489]

2007-03-12  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Fix problems with declaration
	positioning and memory leaks. [Bug 1679072]

2007-03-11  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdIL.c (Tcl_LreverseObjCmd): Ensure that a list is
	correctly reversed even if its internal representation is shared
	without the object itself being shared. [Bug 1675044]

2007-03-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCmdIL (Tcl_LsortObjCmd): changed fix to [Bug 1675116] to
	use the cheaper TclListObjCopy() instead of Tcl_DuplicateObj().

2007-03-09  Andreas Kupries  <andreask@activestate.com>

	* library/platform/shell.tcl: Made more robust if an older platform
	* library/platform/pkgIndex.tcl: package is present in the inspected
	* unix/Makefile.in: shell. Package forget it to prevent errors. Bumped
	* win/Makefile.in: package version to 1.1.3, and updated the Makefiles
	installing it as Tcl Module.

2007-03-09  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* 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
	things into the implementation of the "list" Tcl_ObjType.

2007-03-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclListObj.c (TclLindexList, TclLindexFlat): Moved these
	functions to tclListObj.c from tclCmdIL.c to mirror the way that the
	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.

	* macosx/Tcl.xcodeproj/project.pbxproj: ensure gcc version used by
	* macosx/Tcl.xcodeproj/default.pbxuser: Xcode and configure/make are
	* macosx/Tcl-Common.xcconfig:		consistent and independent of
	gcc_select default and CC env var; fixes for Xcode 3.0.

	* unix/tcl.m4 (Darwin): s/CFLAGS/CPPFLAGS/ in macosx-version-min check
	* unix/configure: autoconf-2.59

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
	list validity test.

2007-03-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclRegexp.c (TclRegAbout): Generate information about a
	regexp as a Tcl_Obj instead of as a string, which is more efficient.

2007-03-07  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl: Adjusted Windows time zone table to handle new US
	DST rules by locale rather than as Posix time zone spec.
	* tests/clock.test (clock-39.6, clock-49.2, testclock::registry):
	Adjusted tests to simulate new US rules.
	* library/tzdata/America/Indiana/Winamac:
	* library/tzdata/Europe/Istanbul:
	* library/tzdata/Pacific/Easter:
	Olson's tzdata2007c.

2007-03-05  Andreas Kupries  <andreask@activestate.com>

	* library/platform/shell.tcl (::platform::shell::RUN): In the case of
	* library/platform/pkgIndex.tcl: a failure put the captured stderr
	* unix/Makefile.in: into the error message to aid in debugging. Bumped
	* win/Makefile.in: package version to 1.1.2, and updated the makefiles
	installing it as Tcl Module.

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
	TclInvalidateStringRep() call when we directly manipulate the intrep
	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
	* tests/dict.test (dict-21.{14,15}):	     non-varying data in an
	aux-data value instead of a (shimmerable) literal. [Bug 1671001]

2007-03-01  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCmdIL.c (Tcl_LinsertObjCmd):	Code simplifications
	and optimizations.

	* generic/tclCmdIL.c (Tcl_LreplaceObjCmd):	Code simplifications
	and optimizations.

	* generic/tclCmdIL.c (Tcl_LrangeObjCmd):	Rewrite in the same
	spirit; avoid shimmer effects rather than react to them.

	* generic/tclCmdAH.c (Tcl_ForeachObjCmd):	Stop throwing away
	* tests/foreach.test (foreach-1.14):	useful error information when
	loop variable sets fail.

	* generic/tclCmdIL.c (Tcl_LassignObjCmd):	Rewrite to make an
	efficient private copy of the list argument, so we can operate on the
	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
	efficient private copies of the variable and value lists, so we can
	operate on them without any special shimmer defense coding schemes.

2007-03-01  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCompCmds.c (TclCompileForeachCmd): Prevent an unexpected
	* tests/foreach.test (foreach-9.1):		infinite loop when the
	variable list is empty and the foreach is compiled. [Bug 1671138]

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
	object, spotted by Don Porter. [Bug 1667990]

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
	case specified in TIP#280. More notes in the comments to the test.

2007-02-20  Jan Nijtmans  <nijtmans@users.sf.net>

	* generic/tclInt.decls: Added "const" specifiers in TclSockGetPort
	* generic/tclIntDecls.h: regenerated
	* generic/*.c:
	* unix/tclUnixChan.c
	* unix/tclUnixPipe.c
	* win/tclWinPipe.c
	* win/tclWinSock.c: Added many "const" specifiers in implementation.

2007-02-20  Don Porter	<dgp@users.sourceforge.net>

	* doc/tcltest.n:	Typo fix. [Bug 1663539]

2007-02-20  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* generic/tclFileName.c:  Handle extended paths on Windows NT and
	* generic/tclPathObj.c:	  above. These have a \\?\ prefix. [Bug
	* win/tclWinFile.c:	  1479814]
	* tests/winFCmd.test:	  Tests for extended path handling.

2007-02-19  Jeff Hobbs	<jeffh@ActiveState.com>

	* unix/tcl.m4: use SHLIB_SUFFIX=".so" on HP-UX ia64 arch.
	* unix/configure: autoconf-2.59

	* generic/tclIOUtil.c (Tcl_FSEvalFileEx): safe incr of objPtr ref.

2007-02-18  Donal K. Fellows  <dkf@users.sf.net>

	* doc/chan.n, doc/clock.n, doc/eval.n, doc/exit.n, doc/expr.n:
	* doc/interp.n, doc/open.n, doc/platform_shell.n, doc/pwd.n:
	* doc/refchan.n, doc/regsub.n, doc/scan.n, doc/tclvars.n, doc/tm.n:
	* doc/unload.n: Apply [Bug 1610310] to fix typos. Thanks to Larry
	Virden for spotting them.

	* doc/interp.n: Partial fix of [Bug 1662436]; rest requires some
	policy decisions on what should and shouldn't be safe commands from
	the "new in 8.5" set.

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
	'unsigned long.'
	* generic/tclTomMath.h: Regenerated.

2007-02-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/re_syntax.n: Corrected description of 'print' class [Bug
	1614687] and enhanced description of 'graph' class.

2007-02-12  Kevin B. Kenny  <kennykb@acm.org>

	* tools/fix_tommath_h.tcl: Added code to patch out a check for
	__x86_64__ that caused Tommath to use __attributes(TI)__ for the
	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
	some of us. This change allows reversion of das's change of 2006-08-18
	that accomplised the same thing on Darwin. [Bugs 1601380, 1603737,
	1609936, 1656265]
	* generic/tclTomMath.h: Regenerated.

2007-02-09  Joe Mistachkin  <joe@mistachkin.com>

	* win/nmakehlp.c: Properly cleanup after nmakehlp, including the
	* win/makefile.vc: vcX0.pch file.

2007-02-08  Jeff Hobbs	<jeffh@ActiveState.com>

	* unix/tclUnixInit.c (TclpCheckStackSpace): do stack size checks with
	unsigned size_t to correctly validate stackSize in the 2^31+ range.
	[Bug 1654104]

2007-02-08  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclNamesp.c:	Corrected broken logic in Tcl_DeleteNamespace
	* tests/namespace.test: introduced in Patch 1577278 that caused
	[namespace delete ::] to be effective only at level #0. New test
	namespace-7.7 should prevent similar error in the future [Bug 1655305]

2007-02-06  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclNamesp.c:	Corrected broken implementation of the
	* tests/namespace.test: TclMatchIsTrivial optimization on [namespace
	children $namespace $pattern].

2007-02-04  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4: use gcc4's __attribute__((__visibility__("hidden"))) if
	available to define MODULE_SCOPE effective on all platforms.
	* unix/configure.in: add caching to -pipe and zoneinfo checks.
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

2007-02-03  Joe Mistachkin  <joe@mistachkin.com>

	* win/rules.vc: Fix platform specific file copy macros for downlevel
	Windows.

2007-01-29  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclResult.c: Added optimization case to TclTransferResult to
	cover common case where there's big savings over the fully general
	path. Thanks to Peter MacDonald. [Bug 1626518]

	* generic/tclLink.c:	Broken linked float logic corrected. Thanks to
	Andy Goth. [Bug 1602538]

	* doc/fcopy.n:	Typo fix. [Bug 1630627]

2007-01-28  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.xcodeproj/project.pbxproj:	  extract build settings that
	* macosx/Tcl.xcodeproj/default.pbxuser:	  were common to multiple
	* macosx/Tcl-Common.xcconfig (new file):  configurations into external
	* macosx/Tcl-Debug.xcconfig (new file):	  xcconfig files; add extra
	* macosx/Tcl-Release.xcconfig (new file): configurations for building
	with SDKs and 64bit; convert legacy jam-based 'Tcl' target to native
	target with single script phase; correct syntax of build setting
	references to use $() throughout.

	* macosx/README: document new Tcl.xcodeproj configurations; other
	minor updates/corrections.

	* generic/tcl.h: update location of version numbers in macosx files.

	* macosx/Tcl.xcode/project.pbxproj: restore 'tcltest' target to
	* macosx/Tcl.xcode/default.pbxuser: working order by replicating
	applicable changes to Tcl.xcodeproj since 2006-07-20.

2007-01-25  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4: integrate CPPFLAGS into CFLAGS as late as possible and
	move (rather than duplicate) -isysroot flags from CFLAGS to CPPFLAGS
	to avoid errors about multiple -isysroot flags from some older gcc
	builds.

	* unix/configure: autoconf-2.59

2007-01-22  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* compat/memcmp.c (memcmp): Reworked so that arithmetic is never
	performed upon void pointers, since that is illegal. [Bug 1631017]

2007-01-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompile.c (TclCompileScript): Reduce the frequency with
	which we issue INST_START_CMD, making bytecode both more compact and
	somewhat faster. The optimized case is where we would otherwise be
	issuing a sequence of those instructions; in those cases, it is only
	ever the first one encountered that could possibly trigger.

2007-01-19  Joe Mistachkin  <joe@mistachkin.com>

	* tools/man2tcl.c: Include stdlib.h for exit() and improve comment
	detection.
	* win/nmakehlp.c: Update usage.
	* win/makefile.vc: Properly build man2tcl.c for MSVC8.

2007-01-19  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/tclMacOSXFCmd.c (TclMacOSXSetFileAttribute): on some versions
	of Mac OS X, truncate() fails on resource forks, in that case use
	open() with O_TRUNC instead.

	* macosx/tclMacOSXNotify.c: accommodate changes to prototypes of
	OSSpinLock(Un)Lock API.

	* macosx/Tcl.xcodeproj/project.pbxproj: ensure HOME and USER env vars
	* macosx/Tcl.xcodeproj/default.pbxuser: are defined when running
						testsuite from Xcode.

	* tests/env.test: add extra system env vars that need to be preserved
	on some Mac OS X versions for testsuite to work.

	* unix/Makefile.in:  Move libtommath defines into configure.in to
	* unix/configure.in: avoid replicating them across multiple
	* macosx/Tcl.xcodeproj/project.pbxproj: buildsystems.

	* unix/tcl.m4: ensure CPPFLAGS env var is used when set. [Bug 1586861]
	(Darwin): add -isysroot and -mmacosx-version-min flags to CPPFLAGS
	when present in CFLAGS to avoid discrepancies between what headers
	configure sees during preprocessing tests and compiling tests.

	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

2007-01-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompile.c (TclCompileScript): Make sure that when parsing
	an expanded literal fails, a correct bytecode sequence is still
	issued. [Bug 1638414]. Also make sure that the start of the expansion
	bytecode sequence falls inside the span of bytecodes for a command.
	* tests/compile.test (compile-16.24): Added test for [Bug 1638414]

2007-01-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclIO.c: Added macros to make usage of ChannelBuffers
	clearer.

2007-01-11  Joe English	 <jenglish@users.sourceforge.net>

	* win/tcl.m4(CFLAGS_WARNING): Remove "-Wconversion". This was removed
	from unix/tcl.m4 2004-07-16 but not from here.
	* win/configure: Regenerated.

2007-01-11  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* win/makefile.vc: Fixes to work better on Win98. Read version numbers
	* win/nmakehlp.c:  from package index file to avoid keeping numbers in
	* win/rules.vc:	   the makefile where they may become de-synchronized.

2007-01-10  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/regcomp.c (compile, freev):	     Define a strategy for
	* generic/regexec.c (exec):		     managing the internal
	* generic/regguts.h (AllocVars, FreeVars):   vars of the RE engine to
	* generic/regcustom.h (AllocVars, FreeVars): reduce C stack usage.
	This will make Tcl as a whole much less likely to run out of stack
	space...

2007-01-09  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompCmds.c (TclCompileLindexCmd):
	* tests/lindex.test (lindex-9.2): Fix silly bug that ended up
	sometimes compiling list arguments in the wrong order. [Bug 1631364]

2007-01-03  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclDate.c: Regenerated to recover a lost fix from patthoyts.
	[Bug 1618523]

2006-12-26  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIO.c (Tcl_GetsObj): Avoid checking for for the LF in a
	possible CRLF sequence when EOF has already been found.

2006-12-26  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclEncoding.c (EscapeFromUtfProc): Clear the
	TCL_ENCODING_END flag when end bytes are written. This fix keep this
	method from writing escape bytes for an encoding like iso2022-jp
	multiple times when the escape byte overlap with the end of the IO
	buffer.
	* tests/io.test: Add test for escape byte overlap issue.

2006-12-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tclUnixThrd.c (Tcl_GetAllocMutex, TclpNewAllocMutex): Add
	intermediate variables to shut up unwanted warnings. [Bug 1618838]

2006-12-19  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixThrd.c (TclpInetNtoa): fix for 64 bit.

	* unix/tcl.m4 (Darwin): --enable-64bit: verify linking with 64bit
	-arch flag succeeds before enabling 64bit build.
	* unix/configure: autoconf-2.59

2006-12-17  Daniel Steffen  <das@users.sourceforge.net>

	* tests/macOSXLoad.test (new file): add testing of .bundle loading and
	* tests/load.test:		    unloading on Darwin (in addition
	* tests/unload.test:		    to existing tests of .dylib
	loading).
	* macosx/Tcl.xcodeproj/project.pbxproj: add building of dltest
	binaries so that testsuite run from Xcode can use them; fix testsuite
	run script
	* unix/configure.in:	   add support for building dltest binaries as
	* unix/dltest/Makefile.in: .bundle (in addition to .dylib) on Darwin.
	* unix/Makefile.in: add stub lib dependency to dltest target.
	* unix/configure: autoconf-2.59

	* tests/append.test: fix cleanup failure when all tests are skipped.

	* tests/chan.test (chan-16.9): cleanup chan event handler to avoid
	causing error in event.test when running testsuite with -singleproc 1.

	* tests/info.test: add !singleTestInterp constraint to tests that fail
	when running testsuite with -singleproc 1. [Bug 1605269]

2006-12-14  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* doc/string.n: Fix example. [Bug 1615277]

2006-12-12  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Now that the new internal structs are
	in use to support operator commands, might as well make them the
	default for [expr] as well and avoid passing every parsed expression
	through the inefficient Tcl_Token array format. This addresses most
	issues in [RFE 1517602]. Assuming no performance disasters result from
	this, much dead code supporting the other implementation might now be
	removed.

	* generic/tclBasic.c:	Final step routing all direct evaluation forms
	* generic/tclCompExpr.c: of the operator commands through TEBC,
	* generic/tclCompile.h: dropping all the routines in tclMathOp.c.
	* generic/tclMathOp.c:	Still needs Engineering Manual attention.

2006-12-11  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Another step with all sorting operator
	* generic/tclCompExpr.c: commands now routing through TEBC via
	* generic/tclCompile.h: TclSortingOpCmd().

2006-12-08  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	 Another step down the path of re-using
	* generic/tclCompExpr.c: TclExecuteByteCode to implement the TIP 174
	* generic/tclCompile.h: commands instead of using a mass of code
	* generic/tclMathOp.c:	duplication. Now all operator commands that
	* tests/mathop.test:	demand exactly one operation are implemented
	via TclSingleOpCmd and a call to TEBC.

	* generic/tclCompExpr.c: Revised implementation of TclInvertOpCmd to
	* generic/tclMathOp.c:	perform a bytecode compile / execute sequence.
	This demonstrates a path toward avoiding mountains of code duplication
	in tclMathOp.c and tclExecute.c.

	* generic/tclCompile.h: Change TclExecuteByteCode() from static to
	* generic/tclExecute.c: MODULE_SCOPE so all files including
	tclCompile.h may call it.

	* generic/tclMathOp.c:	More revisions to make tests pass.
	* tests/mathop.test:

2006-12-08  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclNamesp.c (TclTeardownNamespace): Ensure that dying
	namespaces unstitch themselves from their referents. [Bug 1571056]
	(NsEnsembleImplementationCmd): Silence GCC warning.

	* tests/mathop.test: Full tests for & | and ^ operators

2006-12-08  Daniel Steffen  <das@users.sourceforge.net>

	* library/tcltest/tcltest.tcl: use [info frame] for "-verbose line".

2006-12-07  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompCmds.c:	Additional commits correct most
	* generic/tclExecute.c:		failing tests illustrating bugs
	* generic/tclMathOp.c:		uncovered in [Patch 1578137].

	* generic/tclBasic.c:	Biggest source of TIP 174 failures was that
	the commands were not [namespace export]ed from the ::tcl::mathop
	namespace. More bits from [Patch 1578137] correct that.

	* tests/mathop.test:	Commmitted several new tests from Peter Spjuth
	found in [Patch 1578137]. Many failures now demonstrate issues to fix
	in the TIP 174 implementation.

2006-12-07  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* tests/mathop.test: Added tests for ! ~ eq operators.
	* generic/tclMathOp.c (TclInvertOpCmd): Add in check for non-integral
	numeric values.
	* generic/tclCompCmds.c (CompileCompareOpCmd): Factor out the code
	generation for the chained comparison operators.

2006-12-07  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* tests/exec.test: Fixed line endings (caused win32 problems).

2006-12-06  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompCmds.c:	Revised and consolidated into utility
	* tests/mathop.test:		routines some of routines that compile
	the new TIP 174 commands. This corrects some known bugs. More to come.

2006-12-06  Kevin B. Kenny  <kennykb@acm.org>

	* tests/expr.test (expr-47.12): Improved error reporting in hopes of
	having more information to pursue [Bug 1609936].

2006-12-05  Andreas Kupries  <andreask@activestate.com>

	TIP#291 IMPLEMENTATION

	* generic/tclBasic.c: Define tcl_platform element for pointerSize.
	* doc/tclvars.n:

	* win/Makefile.in: Added installation instructions for the platform
	* win/makefile.vc: package. Added the platform package.
	* win/makefile.bc:
	* unix/Makefile.in:

	* tests/platform.test:

2006-12-05  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclPkg.c:	When no requirements are supplied to a
	* tests/pkg.test:	[package require $pkg] and [package unknown]
	is invoked to find a satisfying package, pass the requirement argument
	"0-" (which means all versions are acceptable). This permits a
	registered [package unknown] command to call [package vsatisfies
	$testVersion {*}$args] without any special handling of the empty $args
	case. This fixes/avoids a bug in [::tcl::tm::UnknownHandler] that was
	causing old TM versions to be provided in preference to newer TM
	versions. Thanks to Julian Noble for discovering the issue.

2006-12-04  Donal K. Fellows  <dkf@users.sf.net>

	TIP#267 IMPLEMENTATION

	* generic/tclIOCmd.c (Tcl_ExecObjCmd): Added -ignorestderr option,
	* tests/exec.test, doc/exec.n:	       loosely from [Patch 1476191]

2006-12-04  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Added implementation for the
	CompileExprTree() routine that can produce expression bytecode
	directly from internal structures with no need to pass through the
	Tcl_Token array representation. Still disabled by default. #undef
	USE_EXPR_TOKENS to try it out.

2006-12-03  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Added expr parsing routines that
	produce a different set of internal structures representing the parsed
	expression, as well as routines that go on to convert those structures
	into the traditional Tcl_Token array format. Use of these routines is
	currently disabled. #undef PARSE_DIRECT_EXPR_TOKENS to enable them.
	These routines will only become really useful when more routines that
	compile directly from the new internal structures are completed.

2006-12-02  Donal K. Fellows  <dkf@users.sf.net>

	* doc/file.n: Clarification of [file pathtype] docs. [Bug 1606454]

2006-12-01  Kevin B. Kenny	 <kennykb@acm.org>

	* libtommath/bn_mp_add.c:	Corrected the effects of a
	* libtommath/bn_mp_div.c:	bollixed 'cvs merge' operation
	* libtommath/bncore.c:		that inadvertently committed some
	* libtommath/tommath_class.h:	half-developed code.

	TIP#299 IMPLEMENTATION

	* doc/mathfunc.n:	Added isqrt() function to docs
	* generic/tclBasic.c:	Added isqrt() math function (ExprIsqrtFunc)
	* tests/expr.test (expr-47.*): Added tests for isqrt()
	* tests/info.test (info-20.2): Added isqrt() to expected math funcs.

2006-11-30  Kevin B. Kenny  <kennykb@acm.org>

	* library/tzdata: Olson's tzdata2006p.
	* libtommath/bn_mp_sqrt.c: Fixed a bug where the initial approximation
	to the square root could be on the wrong side, causing failure of
	convergence.

2006-11-29  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_AppendObjToErrorInfo):  Added
	Tcl_DecrRefCount() on the objPtr argument to plug memory leaks. This
	makes the routine a consumer, which makes it easiest to use.

	* tests/event.test (event-14.*): Corrected a bug where
	TclUnixWaitForFile would present select() with the wrong mask on an

	for reporting and diagnosing [Bug 1602208].

2006-11-27  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c (TclIncrObj):	Correct failure to detect

	1602991]

2006-11-26  Donal K. Fellows  <dkf@users.sf.net>

	* tests/mathop.test, doc/mathop.n: More bits and pieces of the TIP#174
	implementation. Note that the test suite is not yet complete.

2006-11-26  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4 (Linux): --enable-64bit support.	[Patch 1597389]

2006-11-25  Donal K. Fellows  <dkf@users.sf.net>

	TIP#174 IMPLEMENTATION

	* generic/tclMathOp.c (new file): Completed the implementation of the

	* generic/tclCompCmds.c (Tcl*OpCmd, TclCompile*OpCmd):
	* generic/tclBasic.c (Tcl_CreateInterp): Partial implementation of

2006-11-22  Donal K. Fellows  <dkf@users.sf.net>

	TIP#269 IMPLEMENTATION

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Implementation of the [string
	* tests/string.test (string-25.*):	 is list] command, based on
	* doc/string.n:				 work by Joe Mistachkin, with
	enhancements by Donal Fellows for better failindex behaviour.

2006-11-22  Don Porter	<dgp@users.sourceforge.net>

	* tools/genWinImage.tcl (removed):	Removed two files used in
	* win/README.binary (removed):	production of binary distributions
	for Windows, a task we no longer perform. [Bug 1476980]

	already #include's tclInt.h. No need to continue greater exposure.
	[Bug 926500]

2006-11-20  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclBasic.c (Tcl_CreateInterp, TclHideUnsafeCommands):
	* library/init.tcl: Refactored the [chan] command's guts so that it
	does not use aliases to global commands, making the code more robust.

2006-11-17  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c (INST_EXPON):	Corrected crash on

	* tools/genStubs.tcl:	Updated script to no longer produce the
	_ANSI_ARGS_ wrapper in generated declarations. Also revised to accept
	variadic prototypes with more than one fixed argument. (This is
	possible since TCL_VARARGS and its limitations are no longer in use).

2006-11-13  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclIO.c:	When [gets] on a binary channel needs to use
	the "iso8859-1" encoding, save a copy of that encoding per-thread to
	avoid repeated freeing and re-loading of it from the file system. This
	replaces the cached copy of this encoding that the platform
	initialization code used to keep in pre-8.5 releases.

2006-11-13  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclCompExpr.c:	Fix gcc warnings about 'cast to/from

	* macosx/Tcl.xcodeproj/project.pbxproj: remove tclParseExpr.c; when
	running testsuite from inside Xcdoe, skip stack-3.1 (it only fails
	under those circumstances).

	* unix/tcl.m4 (Darwin): suppress linker arch warnings when building
	universal for both 32 & 64 bit and no 64bit CoreFoundation is

2006-11-03  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* tests/event.test (event-11.5):	Rewrote tests to stop Tcl from

	* generic/tclCmdAH.c:	to complete their formatting operations,
	* generic/tclCmdIL.c:	rather than report an error message. This
	* generic/tclCmdMZ.c:	means an interp argument for error message

	* generic/tclInterp.c (AliasObjCmd): Added more explanatory comments.

	* generic/tclBasic.c (TclEvalObjvInternal): Rewrote so that comments

	processing use the Tcl execution stack for working space, and not the
	general heap.

2006-11-01  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixPort.h: ensure MODULE_SCOPE is defined before use, so
	that tclPort.h can once again be included without tclInt.h.

	* generic/tclEnv.c (Darwin): mark _environ symbol as unexported even

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).

	* 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
	* unix/Makefile.in:  files and configure switches to override the
	* unix/configure:    detected default.

2006-10-20  Daniel Steffen  <das@users.sourceforge.net>

	*** 8.5a5 TAGGED FOR RELEASE ***

	* tools/tcltk-man2html.tcl: add support for alpha & beta versions to

2006-10-17  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInterp.c (ApplyObjCmd): fixed bad error in 2006-10-12
	commit: interp released too early. Spotted by mistachkin.

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

	* tclProc.c (SetLambdaFromAny):
	* tests/apply.test (9.1-9.2): plugged intrep leak [Bug 1578454],
	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>

	* unix/tclUnixThrd.c (TclpThreadGetStackSize): on Darwin, use
	* unix/tcl.m4: pthread_get_stacksize_np() API to get thread stack size
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

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
	ensemble rewrite machinery to produce better error messages [Bug
	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,
	event.test, expr.test, fileSystem.test, for.test, http.test, if.test,

	* tests/binary.test:

2006-10-05  Andreas Kupries  <andreask@activestate.com>

	* library/tm.tcl: Fixed bug in TIP #189 implementation, now allowing
	'_' in module names.

2006-10-05  Jeff Hobbs	<jeffh@ActiveState.com>

	* library/http/http.tcl (http::geturl): only do geturl url rfc 3986
	validity checking if $::http::strict is true (default true for 8.5).
	[Bug 1560506]

	* generic/tcl.h: note limitation on changing Tcl_UniChar size
	* generic/tclEncoding.c (UtfToUnicodeProc, UnicodeToUtfProc):
	* tests/encoding.test (encoding-16.1): fix alignment issues in
	unicode <> utf conversion procs. [Bug 1122671]

2006-10-05  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (Tcl_LappendObjCmd):
	* tests/append.test(4.21-22): fix for longstanding [Bug 1570718],
	lappending nothing to non-list. Reported by lvirden

2006-10-04  Kevin B. Kenny  <kennykb@acm.org>

	* tzdata/: Olson's tzdata2006m.

2006-10-01  Kevin B. Kenny  <kennykb@acm.org>

	* tests/clock.test (clock-49.2): Removed a locale dependency that
	caused a spurious failure in the German locale. [Bug 1567956]

2006-10-01  Miguel Sofer  <msofer@users.sf.net>

	* doc/Eval.3 (TclEvalObjv): added note on refCount management for the
	elements of objv. [Bug 730244]

2006-10-01  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* win/tclWinFile.c: Handle possible missing define.

	* win/tclWinFile.c (TclpUtime): [Bug 1420432] file mtime fails for
	* tests/cmdAH.test:		directories on windows

	* tests/winFile.test: Handle Msys environment a little differently in
	getuser function. [Bug 1567956]

2006-09-30  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclUtil.c (Tcl_SplitList): optimisation, [Patch 1344747] by
	dgp.

	* generic/tclInt.decls:
	* generic/tclInt.h:
	* generic/tclIntDecls.h:
	* generic/tclObj.c:
	* generic/tclStubInit.c: added an internal function TclObjBeingDeleted
	to provide info as to the reason for the loss of an internal rep. [FR
	1512138]

	* generic/tclCompile.c:
	* generic/tclHistory.c:
	* generic/tclInt.h:
	* generic/tclProc.c: made Tcl_RecordAndEvalObj not call "history" if
	it has been redefined to an empty proc, in order to reduce the noise
	when debugging [FR 1190441]. Moved TclCompileNoOp from tclProc.c to
	tclCompile.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
	possible NULL derefs, [Bug 1566382] and coverity #33.

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
	detected via testing with the math::bigfloat package [Bug 1567222]

	* 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/makefile.vc:  Additional compiler flags and amd64 support.
	* win/nmakehlp.c:
	* 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
	coverity #51. Extended loop condition, added checking for NULL to
	prevent seg.fault.

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

	* doc/package.n: Fixed nits reported by Daniel Steffen in the TIP#268
	changes.

2006-09-25  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclNotify.c (Tcl_DeleteEvents): Simplified the code in hopes
	of making the invariants clearer and proving to Coverity that the
	event queue memory is managed correctly.

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

	* generic/tclNotify.c (Tcl_DeleteEvents): Make it clear what happens
	when the event queue is mismanaged. [Bug 1564677], coverity bug #10.

2006-09-24  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclParse.c (Tcl_ParseCommand): also return an error if
	start==NULL and numBytes<0. This is coverity's bug #20

	* generic/tclStringObj.c (STRING_SIZE): fix allocation for 0-length
	strings. This is coverity's bugs #54-5

2006-09-22  Andreas Kupries  <andreask@activestate.com>

	* generic/tclInt.h: Moved TIP#268's field 'packagePrefer' to the end
	of the structure, for better backward compatibility.

2006-09-22  Andreas Kupries  <andreask@activestate.com>

	* generic/tclThreadTest.c (TclCreateThread): Use NULL instead of 0 as
	end-of-strings marker to Tcl_AppendResult; the difference matters on
	64-bit machines. [Bug 1562528]

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

	* generic/tclUtil.c:	Dropped ParseInteger() routine. TclParseNumber
	covers the task just fine.

2006-09-19  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclEvent.c (Tcl_VwaitObjCmd): Rewrite so that an exceeded
	limit trapped in a vwait cannot cause a dangerous dangling trace.

2006-09-19  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c (INST_EXPON):	Native type overflow detection
	* tests/expr.test:	was completely broken. Falling back on use of
	bignums for all non-trivial ** calculations until
	native-type-constrained special cases can be done carefully and
	correctly. [Bug 1561260]

2006-09-15  Jeff Hobbs	<jeffh@ActiveState.com>

	* library/http/http.tcl:      Change " " -> "+" url encoding mapping
	* library/http/pkgIndex.tcl:  to " " -> "%20" as per RFC 3986.
	* tests/http.test (http-5.1): bump http to 2.5.3
	* unix/Makefile.in:
	* win/Makefile.in:

2006-09-12  Andreas Kupries  <andreask@activestate.com>

	* unix/configure.in (HAVE_MTSAFE_GETHOST*): Modified to recognize
	HP-UX 11.00 and beyond as having mt-safe implementations of the
	gethost functions.
	* unix/configure: Regenerated, using autoconf 2.59

	* unix/tclUnixCompat.c (PadBuffer): Fixed bug in calculation of the
	increment needed to align the pointer, and added documentation
	explaining why the macro is implemented as it is.

2006-09-11  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* win/rules.vc:	   Updated to install http, tcltest and msgcat as
	* win/makefile.vc: Tcl Modules (as per Makefile.in).
	* win/makefile.vc: Added tommath_(super)class headers.

2006-09-11  Andreas Kupries  <andreask@activestate.com>

	* unix/Makefile.in (install-libraries): Fixed typo tcltest 2.3.9 ->
	2.3.0.

2006-09-11  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixCompat.c: make compatLock static and only declare it
	when it will actually be used; #ifdef parts of TSD that are not always
	needed; adjust #ifdefs to cover all possible cases; fix whitespace.

2006-09-11  Andreas Kupries  <andreask@activestate.com>

	* tests/msgcat.test: Bumped version in auxiliary files as well.
	* doc/msgcat.n:

2006-09-11  Kevin B. Kenny  <kennykb@acm.org>

	* unix/Makefile.in:	Bumped msgcat version to 1.4.2 to be
	* win/Makefile.in:	consistent with dgp's commits of 2006-09-10.

2006-09-11  Don Porter	<dgp@users.sourceforge.net>

	* library/msgcat/msgcat.tcl:	Removed some unneeded [uplevel]s.

2006-09-10  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c:		Corrected INST_EXPON flaw that treated
	* tests/expr.test:		$x**1 as $x**3. [Bug 1555371]

	* doc/tcltest.n:		Bump to version tcltest 2.3.0 to
	* library/tcltest/pkgIndex.tcl: account for new "-verbose line"
	* library/tcltest/tcltest.tcl:	feature.
	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.bc:
	* win/makefile.vc:

	* library/msgcat/msgcat.tcl:	Bump to version msgcat 1.4.2 to
	* library/msgcat/pkgIndex.tcl:	account for modifications.

2006-09-10  Daniel Steffen  <das@users.sourceforge.net>

	* 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.

	* unix/configure.in: add descriptions to new AC_DEFINEs for MT-safe.
	* unix/tcl.m4: add caching to new SC_TCL_* macros for MT-safe wrappers
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

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
	MT-safe starting with Darwin 6 (Mac OSX 10.2).

	* unix/configure: Regenerated with autoconf V2.59

2006-09-08  Andreas Kupries  <andreask@activestate.com>

	* unix/tclUnixCompat.c: Fixed conditions for CopyArray/CopyString, and
	CopyHostent. Also fixed bad var names in TclpGetHostByName.

2006-09-07  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* unix/tclUnixCompat.c: Added fallback to MT-unsafe library calls if
	TCL_THREADS is not defined.
	Fixed alignment of arrays copied by CopyArray() to be on the
	sizeof(char *) boundary.

2006-09-07  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* unix/tclUnixChan.c:	Rewritten MT-safe wrappers to return ptrs to
	* unix/tclUnixCompat.c: TSD storage making them all look like their
	* unix/tclUnixFCmd.c:	MT-unsafe pendants API-wise.
	* unix/tclUnixPort.h:
	* unix/tclUnixSock.c:

2006-09-06  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* unix/tclUnixChan.c: Added TCL_THREADS ifdef'ed usage of MT-safe
	* unix/tclUnixFCmd.c: calls like: getpwuid, getpwnam, getgrgid,
	* unix/tclUnixSock.c: getgrnam, gethostbyname and gethostbyaddr.

	* unix/Makefile.in:
	* unix/configure.in:
	* unix/tcl.m4:
	* unix/configure: Regenerated.

	* unix/tclUnixCompat.c: New file containing MT-safe implementation of
	some library calls.

2006-09-04  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Removed much complexity that is no
	longer needed.

	* tests/main.text (Tcl_Main-4.4):	Test corrected to not be
	timing sensitive to the Bug 1481986 fix. [Bug 1550858]

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.

2006-08-30  Jeff Hobbs	<jeffh@ActiveState.com>

	* generic/tclBasic.c (Tcl_CreateInterp): init iPtr->threadId

	* win/tclWinChan.c [Bug 819667] Improve logic for identifying COM
	ports.

	* 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
	* unix/tclUnixThrd.c (TclpThreadGetStackSize): stack.test to fail on
	FreeBSD (and possibly other Unix platforms).

2006-08-29  Colin McCormack  <coldstore@users.sourceforge.net>

	* generic/tclIOUtil.c:	Added test for NULL return from
	* generic/tclPathObj.c: Tcl_FSGetNormalizedPath which was causing
	* unix/tclUnixFile.c:	segv's per [Bug 1548263]
	* win/tclWinFCmd.c:
	* win/tclWinFile.c:

2006-08-28  Kevin B. Kenny  <kennykb@acm.org>

	* library/tzdata/America/Havana:      Regenerated from Olson's
	* library/tzdata/America/Tegucigalpa: tzdata2006k.
	* library/tzdata/Asia/Gaza:

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>

	* generic/tclClock.c (ClockClicksObjCmd): Fix nested macro breakage
	with TCL_MEM_DEBUG enabled. [Bug 1547662]

2006-08-26  Miguel Sofer  <msofer@users.sf.net>

	* doc/namespace.n:
	* generic/tclNamesp.c:
	* tests/upvar.test: bugfix, docs clarification and new tests for
	[namespace upvar] as follow up to [Bug 1546833], reported by Will
	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
	* tests/compExpr.test:		the new expr parser.
	* tests/compile.test:
	* tests/expr-old.test:
	* tests/expr.test:
	* tests/for.test:

	* tests/while.test:

2006-08-21  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* win/Makefile.in (gdb): Make this target work so that debugging an
	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
	* generic/tclCmdMZ.c (Tcl_TimeObjCmd):	  nanosecond resolution timer
	* generic/tclInt.h:			  to [clock clicks] and [time]
	* unix/configure.in (Darwin):		  when TCL_WIDE_CLICKS defined
	* unix/tclUnixTime.c (TclpGetWideClicks, TclpWideClicksToNanoseconds):
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

	* unix/tclUnixPort.h (Darwin): override potentially faulty configure
	detection of termios availability in all cases, since termios is known
	to be present on all Mac OS X releases since 10.0. [Bug 497147]

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/tclParseExpr.c:	parse error messages.

2006-08-16  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclParseExpr.c:	Replace PrecedenceOf() function with
	prec[] static array.

2006-08-14  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* library/clock.tcl (::tcl::clock::add): Added missing braces to
	clockval validation code. Pointed out on comp.lang.tcl.

2006-08-11  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclNamesp.c: Improvements in buffer management to make
	namespace creation faster. Plus selected other minor improvements to
	code quality. [Patch 1352382]

2006-08-10  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	Misc patches to make code more efficient. [Bug 1530474] (afredd)
	* generic/*.c, macosx/tclMacOSXNotify.c, unix/tclUnixNotfy.c,
	* win/tclWinThrd.c: Tidy up invokations of Tcl_Panic() to promote
	string constant sharing and consistent style.
	* generic/tclBasic.c (Tcl_CreateInterp): More efficient handling of
	* generic/tclClock.c (TclClockInit):	 registration of commands not
						 in global namespace.
	* generic/tclVar.c (Tcl_UnsetObjCmd): Remove unreachable clause.

2006-08-09  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclEncoding.c:	Replace buffer copy in for loop with
	call to memcpy(). Thanks to afredd. [Patch 1530262]

2006-08-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCmdIL.c (Tcl_LassignObjCmd): Make the wrong#args message
	a bit more consistent with those used elsewhere. [Bug 1534628]

	* generic/tclDictObj.c (DictForCmd): Stop crash when attempting to
	iterate over an invalid dictionary. [Bug 1531184]

	* doc/ParseCmd.3, doc/expr.n, doc/set.n, doc/subst.n, doc/switch.n:
	* doc/tclvars.n: Ensure that uses of [expr] in documentation examples
	are also good style (with braces) unless otherwise necessary. [Bug
	1526581]

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.

2006-07-30  Joe English	 <jenglish@users.sourceforge.net>

	* doc/AppInit.3: Fix typo [Bug 1496886]

2006-07-26  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c: Corrected flawed overflow detection in
	* tests/expr.test:	INST_EXPON that caused [expr 2**64] to return
	0 instead of the same value as [expr 1<<64].

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

	* win/tclWinSock.c:	Correct un-initialized Tcl_DString. Thanks to
	afredd. [Bug 1518166]

2006-07-21  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c:
	* tests/execute.test (execute-9.1): dgp's fix for [Bug 1522803].

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
	symbols not available on OSX 10.2 or 10.3, enables binaires built on
	later OSX versions to run on earlier ones.
	* macosx/Tcl.xcodeproj/project.pbxproj: enable weak-linking; turn on
						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
							global initialized
							once
	* unix/tclUnixFCmd.c (DoRenameFile, TclpObjNormalizePath): add runtime
	Darwin release check to determine if realpath is threadsafe.
	* unix/configure.in: add check on Darwin for compiler support of weak
	* unix/tcl.m4:	     import and for AvailabilityMacros.h header; move
	Darwin specific checks & defines that are only relevant to the tcl
	build out of tcl.m4; restrict framework option to Darwin; clean up
	quoting and help messages.
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

	* generic/regc_locale.c (cclass):
	* generic/tclExecute.c (TclExecuteByteCode):
	* generic/tclIOCmd.c (Tcl_ExecObjCmd):
	* generic/tclListObj.c (NewListIntRep):
	* generic/tclObj.c (Tcl_GetLongFromObj, Tcl_GetWideIntFromObj)
	(FreeBignum, Tcl_SetBignumObj):
	* generic/tclParseExpr.c (Tcl_ParseExpr):
	* generic/tclStrToD.c (TclParseNumber):
	* generic/tclStringObj.c (TclAppendFormattedObjs):
	* unix/tclLoadDyld.c (TclpLoadMemory):
	* unix/tclUnixPipe.c (TclpCreateProcess): fix signed-with-unsigned
	comparison and other warnings from gcc4 -Wextra.

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. This
	fixes [Bug 1482718]. Note that the fix will not be effective for code
	that calls the private routine TclProcCompileProc() directly.

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]

2006-05-04  Don Porter	<dgp@users.sourceforge.net>

2006-04-26  Don Porter	<dgp@users.sourceforge.net>

	*** 8.5a4 TAGGED FOR RELEASE ***

	* changes:	Updates for another RC.

	* generic/tclBinary.c:	Revised the handling of the Q and q format
	* generic/tclInt.h:	specifiers for [binary] to account for the

	Nokia N770.

2006-04-25  Don Porter	<dgp@users.sourceforge.net>

	* doc/scan.n:
	* doc/string.n:

	* generic/tclScan.c:	[scan $s %u] is documented to accept only
	* tests/scan.test:	decimal formatted integers. Fixed to match.

2006-04-19  Kevin B. Kenny  <kennykb@acm.org>

	* 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
	(and not at SourceForge).
	* tests/clock.test: Added test case for the above bug.

2006-04-18  Donal K. Fellows  <dkf@users.sf.net>

	* doc/IntObj.3: Minor review fixes, including better documentation of
	the behaviour of Tcl_GetBignumAndClearObj.

2006-04-17  Don Porter	<dgp@users.sourceforge.net>

	* doc/IntObj.3: Documentation changes to account for TIP 237 changes.
	* doc/Object.3: [Bug 1446971]

2006-04-12  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/regc_locale.c (cclass): Redefined the meaning of [:print:]
	to be exactly UNICODE letters, numbers, punctuation, symbols and
	spaces (*not* whitespace). [Bug 1376892]

2006-04-11  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclTrace.c:	Stop some interference between enter traces
	* tests/trace.test:	and enterstep traces. [Bug 1458266]

2006-04-07  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclPathObj.c: Yet another revised fix for the [Bug 1379287]
	* tests/fileSystem.test:	family of path normalization bugs.

2006-04-06  Jeff Hobbs	<jeffh@ActiveState.com>

	* generic/tclRegexp.c (FinalizeRegexp): full reset data to indicate
	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]

	* tests/compExpr-old.test:	Updated testmathfunctions constraint
	* tests/compExpr.test:		to post-TIP-232 world.
	* tests/expr-old.test:
	* tests/expr.test:
	* tests/info.test:

	* tests/indexObj.test:	Corrected other test errors revealed by
	* tests/upvar.test:	testing outside the tcltest application.

	* generic/tclPathObj.c: Revised fix for the [Bug 1379287] family of
	path normalization bugs.

2006-04-06  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4: removed TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING
	define on Darwin. [Bug 1457515]
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

2006-04-05  Don Porter	<dgp@users.sourceforge.net>

	* win/tclWinInit.c:	More careful calls to Tcl_DStringSetLength()
	* win/tclWinSock.c:	to avoid creating invalid DString states. Bump
	* win/tclWinDde.c:	to version 1.3.2. [RFE 1366195]
	* library/dde/pkgIndex.tcl:

	* library/reg/pkgIndex.tcl:	Bump to registry 1.2 because
	* win/tclWinReg.c:	Registry_Unload() is a new public routine
	* win/Makefile.in:	compared to the 1.1.* releases.

	* win/configure.in:	Bump package version numbers.
	* win/configure:	autoconf 2.59

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>

	* generic/tclExecute.c: remove unused var and silence gcc warning

2006-03-29  Jeff Hobbs	<jeffh@ActiveState.com>

	* win/Makefile.in: convert _NATIVE paths to use / to avoid ".\"
	path-as-escape issue.

2006-03-29  Don Porter	<dgp@users.sourceforge.net>

	* changes:	Updates for another RC.

	* generic/tclPathObj.c:	 More fixes for path normalization when /../
	* tests/fileSystem.test: tries to go beyond root.[Bug 1379287]

	* generic/tclExecute.c: Revised INST_MOD implementation to do
	calculations in native types as much as possible, moving to mp_ints
	only when necessary.

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]

	* unix/tcl.m4, win/tcl.m4: []-quote AC_DEFUN functions.

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

	* macosx/Tcl.xcodeproj/default.pbxuser: tcltest to ease test debugging

	* macosx/Tcl.xcode/project.pbxproj:	removed $prefix/share from
	* macosx/Tcl.xcodeproj/project.pbxproj: TCL_PACKAGE_PATH as per change
	to unix/configure.in of 2006-03-13.

	* unix/tclUnixFCmd.c (TclpObjNormalizePath): deal with *BSD/Darwin
	realpath() converting relative paths into absolute paths [Bug 1064247]

2006-03-28  Vince Darley  <vincentdarley@sourceforge.net>

	* generic/tclIOUtil.c: fix to nativeFilesystemRecord comparisons
	(lesser part of [Bug 1064247])

2006-03-27  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* win/tclWinTest.c:	Fixes for [Bug 1456373] (mingw-gcc issue)

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.
	* generic/tclIOGT.c, generic/tclIORChan.c, unix/tclUnixChan.c:
	* unix/tclUnixPipe.c, win/tclWinChan.c, win/tclWinConsole.c:
	* win/tclWinPipe.c, win/tclWinSerial.c, win/tclWinSock.c:

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>

	* generic/tclExecute.c: Corrections to INST_EXPON detection of
	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
	now be built from the tcl source distribution with "rpmbuild -tb
	<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>

	* changes:	Updates for another RC.

	* generic/tclStrToD.c:	One of the branches of AccumulateDecimalDigit
	* tests/parseExpr.test: did not. [Bug 1451233]

	* tests/env.test:	Preserve case of saved env vars. [Bug 1409272]

2006-03-21  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclInt.decls:	 implement globbing for HFS creator & type
	* macosx/tclMacOSXFCmd.c:codes and 'hidden' flag, as documented in
	* tests/macOSXFCmd.test: glob.n; objectified OSType handling in [glob]
	* unix/tclUnixFile.c:	 and [file attributes]; fix globbing for
	hidden files with pattern==NULL arg. [Bug 823329]
	* 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.

2006-03-20  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* tests/cmdAH.test, tests/fCmd.test, tests/unixFCmd.test:
	* tests/winFCmd.test: Cleanup of some test constraint handling, and a
	few other minor issues.

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.

	Small optimisation to implementation of pattern==NULL case of TclGlob,
	and clarification to the documentation. [Tclvfs bug 1405317]

2006-03-18  Vince Darley  <vincentdarley@sourceforge.net>

	* tests/fCmd.test: added knownBug test case for [Bug 1394972]

	* tests/winFCmd.test:
	* tests/tcltest.test: corrected tests to better account for behaviour
	of writable/non-writable directories on Windows 2000/XP. This, with
	the previous patches, closes [Bug 1193497]

2006-03-17  Andreas Kupries <andreask@activestate.com>

	* doc/chan.n: Updated with documentation for the commands 'chan
	create' and 'chan postevent' (TIP #219).

	* doc/refchan.n: New file. Documentation of the command handler API
	for reflected channels (TIP #219).

2006-03-17  Joe Mistachkin <joe@mistachkin.com>

	* unix/tclUnixPort.h: Include pthread.h prior to pthread_np.h [Bug
	1444692]

	* win/tclWinTest.c: Corrected typo of 'initializeMutex' that prevented
	successful compilation.

2006-03-16  Andreas Kupries <andreask@activestate.com>

	* doc/open.n: Documented the changed behaviour of 'a'ppend mode.

	* tests/io.test (io-43.1 io-44.[1234]): Rewritten to be self-contained
	with regard to setup and cleanup. [Bug 681793]

	* 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>

	* win/tclWinFile.c: fix to 'file writable' in certain XP directories.
	Thanks to fvogel and jfg. [Patch 1344540] Modified patch to make use
	of existing use of getSecurityProc.

2006-03-08  Don Porter	<dgp@users.sourceforge.net>

	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

	[Patch 958222]

2006-02-17  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclIORChan.c: Revised error message generation and handling
	* tests/ioCmd.test:	of exceptional return codes in the channel
	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>

	missing work in error reporting

2006-02-01  Don Porter	<dgp@users.sourceforge.net>

	TIP#194 IMPLEMENTATION

	* doc/apply.n:	(New file)	New command [apply]. [Patch 944803]
	* doc/uplevel.n:
	* generic/tclBasic.c:
	* generic/tclInt.h:

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.
