2005-06-22  Don Porter  <dgp@users.sourceforge.net>

        * win/tclWinFile.c:     Potential buffer overflow.  [Bug 1225571]
        Thanks to Pat Thoyts for discovery and fix.

2005-06-22  Kevin Kenny <kennykb@acm.org>

	* generic/tclInt.h:    			    Changed the finalization
	* generic/tclEvent.c (Tcl_Finalize):        logic to defer the
	* generic/tclIO.c (TclFinalizeIOSubsystem): shutdown of the pipe
	* unix/tclUnixPipe.c (TclFinalizePipes):    management until after
	* win/tclWinPipe.c (TclFinalizePipes):      all channels have been
	    closed, in order to avoid a situation where the Windows
	    PipeCloseProc2 would re-establish the exit handler after
	    exit handlers had already run, corrupting the heap.
	    [Bug #1225727]
	Also corrected a potential read of uninitialized memory in
	PipeClose2Proc [Bug #1225044]
	
2005-06-21  Andreas Kupries <andreask@activestate.com>

	* generic/tclInt.h: Followup to change made on 2005-06-18 by
	  Daniel Steffen. There are compilers (*) who error out on the
	  redefinition of WORDS_BIGENDIAN. We have to undef the previous
	  definition (on the command line) first to make this
	  acceptable. (*): AIX native.

2005-06-21  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclFileName.c: Changed [file split] and [file join]
	to treat Windows drive letters similarly to ~ syntax and make
	sure that they appear with "./" in front when they are in
	intermediate components of the path. [Bug 1194458]
	* tests/fileName.test: Added test for the above bug.
	
2005-06-21  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclBasic.c:   Added missing walk of the list of active traces
        * generic/tclTrace.c:   to cleanup references to traces being deleted.
        * generic/tclInt.h:     [Bug 1201035] Made the walk of the active trace
        * tests/trace.test (trace-34.*): list aware of the direction of trace
	scanning, so the proper correction can be made. [Bug 1224585]

2005-06-21  Donal K. Fellows  <dkf@users.sf.net>

	* unix/tcl.m4 (SC_ENABLE_SYMBOLS): Only enable the 'compile'
	special debugging feature when requested in configure.in; removes
	irrelevant junk from the configure files of extensions that use
	Tcl's tcl.m4.

2005-06-20  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCompile.h (INST_PUSH_RETURN_OPTIONS): New opcode to allow
	* generic/tclCompCmds.c (TclCompileCatchCmd):	   compilation of TIP90
	* generic/tclCompile.c:				   catch [Bug 1219112]
	* generic/tclExecute.c (TclExecuteByteCode): 

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Ensure we spill to the
	command form in all cases where it generates an error.

2005-06-20  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Generate an error if a mode
	argument like -exact is passed more than once to the switch
	command. The previous implementation silently accepted invalid switch
	invocations like [switch -exact -glob $str ...].
	* tests/for.test: Check some error cases when invoking continue and
	break inside a for loop next script.
	* tests/switch.test: Add checks for shortened version of a mode
	argument like -exact. Add test for more than one mode argument. Add
	test for odd case of passing a variable as a body script.

2005-06-18  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclInt.h: ensure WORDS_BIGENDIAN is defined correctly with
	fat compiles on Darwin (i.e. ppc and i386 at the same time), the
	configure AC_C_BIGENDIAN check is not sufficient in this case because
	a single run of the compiler builds for two architectures with
	different endianness.

	* unix/tcl.m4 (Darwin): add -headerpad_max_install_names to LDFLAGS to
	ensure we can always relocate binaries with install_name_tool.

	* unix/configure: autoconf-2.59

2005-06-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Fix for [Bug 1154163]; only
	* tests/format.test: insert 'l' modifier when it is needed.

2005-06-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclTimer.c (AfterDelay): Split out the code to manage
	synchronous-delay [after] commands.
	* tests/interp.test (interp-34.10): Time limits and synch-delay
	[after] did not mix well... [Bug 1221395]

2005-06-14  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken): Only delete a
	* tests/namespace.test (namespace-49.2): command from the hashtable on
	reentrant processing if it has not been already deleted; at least
	three deletes of the same command are possible. [Bug 1220058]
	* generic/tclTrace.c (TraceCommandProc): Remove bogus error message
	creation when traces trigger in situations where the command has
	already been deleted.

2005-06-13  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFCmd.c: correct fix to file mkdir 2005-06-09, [Bug 1219176]

2005-06-12  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCompCmds.c: Factor out some common idioms into named
	forms for greater clarity.

2005-06-10  Donal K. Fellows  <dkf@users.sf.net>

	* doc/chan.n: Fold in the descriptive parts of the documentation
	for all the commands that [chan] builds on top of.

2005-06-09  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFCmd.c: fix to race condition in file mkdir [Bug 1217375]
	* doc/glob.n: improve glob documentation [Bug 1190891]

2005-06-09  Donal K. Fellows  <dkf@users.sf.net>

	* doc/expr.n, doc/mathfunc.n: Fix minor typos [Bug 1211078] and
	add mention of distinctly-relevant [namespace path] subcommand.

2005-06-07  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.h:		Reduced the Tcl_ObjTypes "index",
	* generic/tclIndexObj.c:	"ensembleCmd", "localVarName", and
	* generic/tclNamesp.c:		"levelReference" to file static scope.
	* generic/tclProc.c:
	* generic/tclVar.c:

	* generic/tclObj.c:	Restored registration of the "procbody"
	Tcl_ObjType, as required by the tclcompiler application.

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

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

	* generic/tclIO.c (Tcl_ChannelTruncateProc): Stop proliferation of
	* generic/tcl.h:			     channel type versions
	* doc/CrtChannel.3:			     following advice from AKu

	Bump patchlevel to a4 to distinguish from a3 release.

	* generic/tclInt.h (INTERP_TRACE_IN_PROGRESS): Add flag so the error
	* generic/tclIndexObj.c (Tcl_WrongNumArgs):    messages from ensembles

	TIP#208 IMPLEMENTATION

	* library/init.tcl: Create the chan ensemble.
	* tests/chan.test: Rudimentary test suite.
	* doc/chan.n: General documentation.

	TRUNCATION API (part of TIP#208)
	* generic/tcl.h, generic/tcl.decls: Declaration of the API.
	* doc/CrtChannel.3, doc/OpenFileChnl.3: Documentation of the API.
	* generic/tclBasic.c (Tcl_CreateInterp): Create the mapping into Tcl.
	* generic/tclIOCmd.c (TclChanTruncateObjCmd): Implementation of
	Tcl-level truncation API.
	* generic/tclIO.c (Tcl_TruncateChannel): Generic C-level
	truncation API implementation.
	* unix/tclUnixChan.c (FileTruncateProc): Basic implementation of
	truncating driver.

	* win/tclWinChan.c (FileTruncateProc): Added implementation of
	file truncation for Windows.
	* tests/chan.test (chan-15.2): Added real test of truncation.

2005-06-06  Kevin B. Kenny  <kennykb@acm.org>

	* win/tclWin32Dll.c: Corrected another buglet in the assembly
	code for stack probing on Win32/gcc. [Bug #1213678]
	* generic/tclObj,c: Added missing 'static' on definition of
	UpdateStringOfBignum, and removed a 'switch' on a 'long long'
	operand (which HP-UX native 'cc' seems unable to handle).
	[Bug #1215775]
	
2005-06-04  Jeff Hobbs  <jeffh@ActiveState.com>

	*** 8.5a3 TAGGED FOR RELEASE ***

	* unix/Makefile.in (dist): add libtommath

2005-06-03  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* library/parray.tcl (parray): Only generate the sorted list of
	element names once. Thanks to Andreas Leitgeb for spotting this.

2005-06-03  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Makefile: fixed 'embedded' target.

2005-06-02  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/Makefile.in (html): add BUILD_HTML_FLAGS optional var
	* tools/tcltk-man2html.tcl: add a --useversion to prevent
	confusion when multiple Tcl source dirs exist.

2005-06-01  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:	For compatibility with earlier Tcl releases,
	* generic/tclResult.c:	when a command procedure simply does a
	* generic/tclTest.c:	"return TCL_RETURN;" we must interpret that
	* tests/result.test:	the same as
	"return Tcl_SetReturnOptions(interp, Tcl_NewObj());"  [Bug 1209759].

2005-06-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Allow compilation
	of -nocase -glob [switch]es (only one we know how to compile).

	TIP#241 IMPLEMENTATION from Joe Mistachkin

	* generic/tclCmdIL.c (Tcl_LsearchObjCmd, Tcl_LsortObjCmd): 
	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Implementation of -nocase
	option for [lsearch], [lsort] and [switch] commands.
	* win/tclWinPort.h: Win uses nonstandard function names...
	* tests/cmdIL.test, tests/lsearch.test, tests/switch.test: Tests
	* doc/lsearch.n, doc/lsort.n, doc/switch.n: Docs

	* generic/tclCompCmds.c (TclCompileLindexCmd): Compile the most
	common case of [lindex] more efficiently.

	* unix/tclUnixNotfy.c (Tcl_FinalizeNotifier): Pass the correct
	number of arguments to Tcl_JoinThread.

2005-05-31  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/configure.in, unix/tcl.m4: Standardize generation of help
	messages to always use AC_HELP_STRING and always (except for
	--with-tcl and --with-tk, where the default is complex) say what
	the default is.

2005-05-31  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* unix/tclUnixNotfy.c: the notifier thread is now created as
	joinable thread and it is properly joined in Tcl_FinalizeNotifier.
	This is an attempt to fix the Tcl Bug #1082283.

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

	* win/tclWinThrd.c: Fixed Tcl Bug #1204064.

2005-05-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	TIP #229 IMPLEMENTATION

	* generic/tclNamesp.c (Tcl_FindCommand, TclResetShadowedCmdRefs) 
	(NamespacePathCmd, SetNsPath, UnlinkNsPath, TclInvalidateNsPath):
	Implementation of the [namespace path] command and the command
	name resolution engine.

	Ensure that people don't see stale paths.
	* generic/tclInt.h (Namespace, NamespacePathEntry): Structure defs.
	* generic/tclCmdIL.c (InfoCommandsCmd): Updates to [info commands].

2005-05-26  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Makefile: moved & corrected EMBEDDED_BUILD check.
	
	* unix/configure.in: corrected framework finalization to softlink
	stub library to Versions/8.x subdir instead of Versions/Current.
	* unix/configure: autoconf-2.59

2005-05-25  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): add necessary cast

2005-05-25  Don Porter  <dgp@users.sourceforge.net>

	TIP#182 IMPLEMENTATION	[Patch 1165062]

	* doc/mathfunc.n:	New built-in math function bool().
	* generic/tclBasic.c:
	* tests/expr.test:
	* tests/info.test:

2005-05-24  Don Porter  <dgp@users.sourceforge.net>

	* library/init.tcl:	Updated [unknown] to be sure the [return]
	* tests/init.test:	options from an auto-loaded command are
	seen correctly by the caller.

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

	* tests/env.test: added DYLD_FRAMEWORK_PATH to the list of env vars
	that need to be handled specially.

	* macosx/Makefile:
	* macosx/README:
	* macosx/Tcl-Info.plist.in (new file):
	* unix/Makefile.in:
	* unix/configure.in:
	* unix/tcl.m4:
	* unix/tclUnixInit.c: moved all Darwin framework build support from
	macosx/Makefile into the standard unix configure/make buildsystem, the
	macosx/Makefile is no longer required to build Tcl.framework (but its
	functionality is still available for backwards compatibility).
	* unix/configure: autoconf-2.59

	* generic/tclIOUtil.c (TclLoadFile):
	* generic/tclInt.h:
	* unix/tcl.m4:
	* unix/tclLoadDyld.c: added support for [load]ing .bundle binaries in
	addition to .dylib's: .bundle's can be [unload]ed (unlike .dylib's),
	and can be [load]ed from memory, e.g. directly from VFS without
	needing to be written out to a temporary location first. [Bug 1202209]
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): change [time] called with a
	count > 1 to return a string with a float value instead of a rounded
	off integer. [Bug 1202178]

	* doc/expr.n:
	* doc/string.n: fixed roff syntax complaints from 'make html'.

2005-05-20  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclParseExpr.c:       Corrected parser to recognize all
	boolean literals accepted by Tcl_GetBoolean, including prefixes
	like "y" and "f", and to allow "eq" and "ne" as function names
	in the proper context.  [Bug 1201589].

2005-05-19  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclBasic.c (TclEvalObjvInternal): Rewrite for greater
	clarity; although 'goto' is Bad, the contortions you have to go
	through to avoid it can be worse...

2005-05-19  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier): fixed crashing
	CFRelease of runLoopSource in Tcl_InitNotifier (reported by Zoran):
	CFRunLoopAddSource doesn't CFRetain, so can only CFRelease the
	runLoopSource in Tcl_FinalizeNotifier.

2005-05-18  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_ExprBoolean):	Rewrite as wrapper around
	Tcl_ExprBooleanObj.

	* generic/tclCmdMZ.c ([string is boolean/true/false]):  Rewrite
	dropping string-based Tcl_GetBoolean call, so that internal reps
	are kept for subsequent quick boolean operations.

	* generic/tclExecute.c:	Dropped most special handling of the
	"boolean" Tcl_ObjType, since that type should now be rarely
	encountered.

	* doc/BoolObj.3:	Rewrite of documentation dropping many details
	about the internals of Tcl_Objs.  Shorter documentation focuses on
	the function and use of the routines.

	* generic/tclInt.h:	Revision to the "boolean" Tcl_ObjType, so
	* generic/tclObj.c:	that only string values like "yes" and "false"
	* tests/obj.test:	are kept as the "boolean" Tcl_ObjType.  The
	string values "0" and "1" are kept as "int" Tcl_ObjType, which also
	produce quick calls to Tcl_GetBooleanFromObj().  Since this internal
	change means a Tcl_ConvertToType to a "boolean" Tcl_ObjType might
	not produce a Tcl_Obj of type "boolean", the registration of the
	"boolean" type is also removed.
	***POTENTIAL INCOMPATIBILITY***
	For callers of Tcl_GetObjType on the type name "boolean".  

2005-05-17  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclObj.c (TclInitObjSubsystem):	Removed the
	* tests/listObj.test:	registration of the Tcl_ObjType's "list",
	* tests/obj.test:	"procbody", "index", "ensembleCommand",
	"localVarName", and "levelReference".  The only reason to register
	a Tcl_ObjType is to have it returned by Tcl_GetObjType, and the
	only reason for that is to retrieve a (Tcl_ObjType *) to pass to
	Tcl_ConvertToType().  None of the types above can support a
	Tcl_ConvertToType() call; they panic.  Better not to offer something
	than to lead users into a panic.
	***POTENTIAL INCOMPATIBILITY***
	For callers of Tcl_GetObjType on the type names listed above.

2005-05-15  Kevin Kenny  <kennykb@users.sourceforge.net>

	* win/tclWin32Dll.c: conditioned definition of
	EXCEPTION_REGISTRATION structures on HAVE_NO_SEH, to fix a bug in
	buildability on MSVC.
	
2005-05-14  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclInt.decls:
	* generic/tclTest.c:
	* generic/tclUtil.c:
	* win/tclWin32Dll.c: fixed link error due to direct access by
	tclTest.c to the MODULE_SCOPE tclPlatform global: renamed existing
	TclWinGetPlatform() accessor to TclGetPlatform() and moved it to
	generic code so that it can be used by on all platforms where
	MODULE_SCOPE is enforced.
	
	* macosx/tclMacOSXBundle.c:
	* unix/tclUnixInit.c: 
	* unix/tcl.m4 (Darwin): made use of CoreFoundation API configurable
	and added test of CoreFoundation availablility to allow building on
	ppc64, replaced HAVE_CFBUNDLE by HAVE_COREFOUNDATION; test for
	availability of Tiger or later OSSpinLockLock API.

	* unix/tclUnixNotfy.c:
	* unix/Makefile.in:
	* macosx/tclMacOSXNotify.c (new file): when CoreFoundation is
	available, use new CFRunLoop based notifier: allows easy integration
	with other event loops on Mac OS X, in particular the TkAqua Carbon
	event loop is now integrated via a standard tcl event source (instead
	of TkAqua upon loading having to finalize the exsting notifier and 
	replace it with its custom version). [Patch 1202052]

	* tests/unixNotfy.test: don't run unthreaded tests on Darwin
	since notifier may be using threads even in unthreaded core.

	* unix/tclUnixPort.h:
	* unix/tcl.m4 (Darwin): test for thread-unsafe realpath durning
	configure, as Darwin 7 and later realpath is threadsafe.
	
	* macosx/Makefile: enable configure caching.

	* unix/configure.in: wrap tclConfig.h header in #ifndef _TCLCONFIG so
	that it can be included more than once without warnings from gcc4.0
	(as happens e.g. when including both tclInt.h and tclPort.h)

	* macosx/tclMacOSXBundle.c:
	* unix/tclUnixChan.c:
	* unix/tclLoadDyld.c:
	* unix/tclUnixInit.c: fixed gcc 4.0 warnings.

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

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

2005-05-13  Kevin Kenny  <kennykb@acm.org>

	* win/tclWin32Dll.c: Further rework of the SEH logic.  All
	                     EXCEPTION_REGISTRATION records are now
			     in the activation record rather than pushed
	                     on the stack.
	
2005-05-13  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Dropped the TCL_NO_MATH configuration.
	* generic/tclBinary.c:	It's believed this has not been working
	* generic/tclExecute.c: in a long time.  Tcl needs math.h.
	* unix/Makefile.in:	[RFE 1200680].

2005-05-12  Kevin Kenny  <kennykb@acm.org>

	* doc/mathfunc.n: Changed NAME line to match the name of the page.
	
2005-05-11  Kevin Kenny  <kennykb@acm.org>

	* generic/tclStrToD.c (TclStrToD, RefineResult, ParseNaN):
	Changed the code to cast 'char' to UCHAR explicitly when
	using ctype macros, to silence complaints from the Solaris
	compiler.
	
2005-05-10  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixFCmd.c: add lint attr to enum to satisfy strictly
	compliant compilers that don't like trailing ,s.

	* tests/string.test: string-10.[21-30]
	* generic/tclCmdMZ.c (Tcl_StringObjCmd): add extra checks to
	prevent possible UMR in unichar cmp function for string map.

2005-05-10  Kevin Kenny  <kennykb@acm.org>

	* generic/tclBinary.c (FormatNumber): Fixed a bug where NaN's
	resulted in reads of uninitialized memory when using 'd',
	'q', or 'Q' format.
	* generic/tclStrToD.c (ParseNaN, TclFormatNaN): Added code to
	handle the peculiarities of HP's PA_RISC, which uses a different
	'quiet' bit in NaN from everyone else.
	* libtommath/tommath_superclass.h: Corrected C++-style comment.
	
2005-05-10  Kevin Kenny  <kennykb@acm.org>

	Merged all changes on kennykb-numerics-branch back into the
	HEAD.  TIP's 132 and 232 are now Final.
	
2005-05-10  Kevin Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch] Merged changes from HEAD.
	
2005-05-10  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (ExponLong, ExponWide): 
	* tests/expr.test (expr-23.34/35): fixed special case 'i**0' for
	i>0 [Bug 1198892] 

2005-05-09  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]
	* win/tclWin32Dll.c (TclpCheckStackSpace, TclWinCPUID):
	        Reworked structured event handling to function even
		with -fomit-frame-pointers.
	
2005-05-08  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]
	* generic/tclStrToD.c: Made code more portable by finding a
	                       workaround for MSVC's 'volatile' issue that
			       does not require conditional compilation.
	* win/tclWin32Dll.c (TclWinCPUID): Removed structured event
	                                   handling from the GCC code
					   since (a) bad code is generated
					   by the instruction scheduling
					   with -O2, and (b) it's not
					   needed on any reasonably modern
					   CPU.
	
2005-05-07  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]
	* generic/tclEvent.c:  Moved initialization of tclStrToD.c's
	* generic/tclInt.h:    static constants into a procedure called

			       an issue where MSVC ignored the 'volatile'
			       specifier, causing incorrect comparison
			       of an underflowed number against zero.

	Dredge the NaN out of the internal representation if

	* generic/tclObj.c (Tcl_GetDoubleFromObj): 
	Restored silent overflow/underflow behaviour that the merge
	of 2004-04-25 messed up.  Thanks to Don Porter for calling

	untreaded core).

	* win/tclWinNotify.c (Tcl_WaitForEvent):

	zero wait times (as specified in TIP 233).

	* unix/Makefile.in: added @PLAT_SRCS@ to SRCS and split out NOTIFY_SRCS
	from UNIX_SRCS for parity with UNIX_OBJS & NOTIFY_OBJS.

	* unix/tcl.m4 (Darwin): added configure checks for recently added linker
	flags -single_module and -search_paths_first to allow building with
	older tools (and on Mac OS X 10.1), use -single_module in SHLIB_LD and
	not just T{CL,K}_SHLIB_LD_EXTRAS, added unexporting from Tk of symbols
	from libtclstub to avoid duplicate symbol warnings, added PLAT_SRCS
	definition for Mac OS X, defined MODULE_SCOPE to __private_extern__.

2005-04-22  Don Porter  <dgp@users.sourceforge.net>

	The 2005-04-21 changes to Tcl_GetBooleanFromObj were done to bring
	it into agreement with its docs.  Further investigation reveals it
	was the docs that were incorrect.  

	* doc/BoolObj.3:	Corrections to the documentation of
	Tcl_GetBooleanFromObj to bring it into agreement with what this
	public interface has always done, including noting the difference
	in function between Tcl_GetBooleanFromObj and Tcl_GetBoolean.

	* generic/tclGet.c:	Revised Tcl_GetBoolean to no longer be a
	wrapper around Tcl_GetBooleanFromObj (different function!).

	* generic/tclObj.c:	Removed TclGetTruthValueFromObj routine 
	that was added yesterday.  Revisions so that only
	Tcl_GetBoolean-approved values get the "boolean" Tcl_ObjType.
	This retains the fix for [Bug 1187123].
	* tests/string.test:	Test string-23.0 for Bug 1187123.

	* generic/tclInt.h:	Revert most recent change.
	* generic/tclBasic.c:
	* generic/tclCompCmds.c:
	* generic/tclDictObj.c:
	* generic/tclExecute.c:
	* tests/obj.test:

2005-04-21  Don Porter  <dgp@users.sourceforge.net>

	* doc/GetInt.3:	Convert argument "string" to "str" to agree with code.
	Also clarified a few details on int and double formats.
	* generic/tclGet.c:	Radical code simplification.  Converted
	Tcl_GetFoo() routines into wrappers around Tcl_GetFooFromObj().
	Reduces code duplication, and the resulting potential for inconsistency.

	* generic/tclObj.c:	Several changes:

	  - Re-ordered error detection code so all values with trailing
	    garbage receive a "not an integer" message instead of an
	    "integer too large" message.
	  - Removed inactive code meant to deal with strtoul* routines that
	    fail to parse leading signs.  All of them do, and if any are
	    detected that do not, the correct fix is replacement with
	    compat/strtoul*.c, not a lot of special care by the callers.
	  - Tcl_GetDoubleFromObj now avoids shimmering away a "wideInt" intrep.
	  - Fixed Tcl_GetBooleanFromObj to agree with its documentation and
	    with Tcl_GetBoolean, accepting only "0" and "1" and not other
	    numeric strings.  [Bug 1187123]
	  - Added new private routine TclGetTruthValueFromObj to perform
	    the more permissive conversion of numeric values to boolean
	    that is needed by the [expr] machinery.

	* generic/tclInt.h (TclGetTruthValueFromObj):	New routine.
	* generic/tclExecute.c:	Updated callers to call new routine.
	* generic/tclBasic.c:	Updated callers to call new routine.
	* generic/tclCompCmds.c:	Updated callers to call new routine.
	* generic/tclDictObj.c:	Updated callers to call new routine.
	* tests/obj.test:	Corrected bad tests that actually expected
	values like "47" and "0xac" to be accepted as booleans.

	* generic/tclLiteral.c:	Disabled the code that forces some literals
	into the "int" Tcl_ObjType during registration.  We can re-enable it
	if this change causes trouble, but it seems more sensible to let
	Tcl's "on-demand" shimmering rule, and not try to pre-guess things.

	[Bug 1084111] 

2005-04-16  Zoran Vasiljevic <vasiljevic@users.sf.net>

	* generic/tclIOUtil.c: force clenaup of the interp result
	in TclLoadFile(). Some implementations of TclpFindSymbol()
	will seed the interp result with error message when unable
	to find the requested symbol (this is not considered to
	be an error).

	Set of changes correcting huge memory waste (not a leak)
	when a thread exits. This has been introduced in 8.4.7
	within an attempt to correctly cleanup after ourselves when
	Tcl library is being unloaded with the Tcl_Finalize() call.

	This fixes the Tcl Bug #1178445.

	* generic/tclInt.h: added prototypes for TclpFreeAllocCache()
	and TclFreeAllocCache()

	* generic/tclThreadAlloc.c: modified TclFinalizeThreadAlloc()
	to explicitly call TclpFreeAllocCache with the NULL-ptr as 
	argument signalling cleanup of private tsd key used only by
	the threading allocator.

	* unix/tclUnixThrd.c: fixed TclpFreeAllocCache() to recognize
	when being called with NULL argument. This is a signal for it
	to clean up the tsd key associated with the threading allocator.

	* win/tclWinThrd.c: renamed TclWinFreeAllocCache to TclpFreeAllocCache
	and fixed to recognize when being called with NULL argument.
	This is a signal for it to clean up the tsd key associated with the
	threading allocator.

	a later time.

2005-04-13  David Gravereaux <davygrvy@pobox.com>

	* generic/tclIO.c (Tcl_SetChannelBufferSize): Lowest size limit
	* tests/io.test: 	changed from ten bytes to one byte.  Need
	* tests/iogt.test:	for this change was proven by
	Ross Cartlidge <rossc@cisco.com> where [read stdin 1] was grabbing
	10 bytes followed by starting a child process that was intended to
	continue reading from stdin.  Even with -buffersize set to one,
	nine chars were getting lost by the buffersize over reading for
	the native read() caused by [read].

2005-04-13  Don Porter  <dgp@users.sourceforge.net>

	* unix/tclUnixInit.c (TclpGetEncodingNameFromEnvironment):  Reversed
	order of verifying candidate [encoding system] value, checking against
	a table in memory first before calling Tcl_GetEncoding and potentially
	scanning through the filesystem.  Also ordered the table so that a
	binary search could be used within it.  Improves startup time a bit
	more on some systems.

	* doc/fcopy.n: Improved documentation on copying binary files,
	added an example and mentioned the use of [file copy].
	* doc/fconfigure.n: Improved documentation of -encoding binary
	option.
	This is all following comments from Steve Manning <steve@manning.net>
	on comp.lang.tcl that the current documentation was not clear.

2005-04-13  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c:Commented out the functions

	not debugging the compiler, as they are never called in that case.

2005-04-12  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInterp.c:	Corrected bad syntax of Tcl_Panic() call.

	* generic/tclUtil.c (TclGetProcessGlobalValue):	More robust handling
	of bad TclInitProcessGlobalValueProc behavior; an immediate panic
	rather than a mysterious crash later.

	* generic/tclEncoding.c:	Several changes to the way the
	encodingFileMap cache is maintained.  Previously, it was attempted
	to keep the file map filled and up to date with changes in the
	encoding search path.  This contributed to slow startup times since
	it required an expensive "glob" operation to fill the cache.  Now the
	validity of items in the cache are checked at the time they are
	used, so the cache is permitted to fall out of sync with the
	encoding search path.  Only [encoding names] and Tcl_GetEncodingNames()
	now pay the full expense.  [Bug 1177363]

2005-04-12  Kevin B. Kenny  <kennykb@acm.org>

	* compat/strstr.c: Added default definition of NULL to

	* generic/tclListObj.c:
	* generic/tclStubInit.c:
	* generic/tclVar.c: Changed the internal representation of lists
	to (a) reduce the malloc/free calls at list creation (from 2 to
	1), (b) reduce the cost of handling empty lists (we now never
	create a list internal rep for them), (c) allow refcounting of the
	list internal rep. The latter permits insuring that the pointers
	returned by Tcl_ListObjGetElements remain valid even if the object
	shimmers away from its original list type. This is [Patch 1158008]
	
	* generic/tclExecute.c:
	* generic/tclInt.h:
	* generic/tclObj.c:
	* generic/tclStringObj.c: 
	(1) defined new internal macros for creating and setting
	frequently used obj types (int,long, wideInt, double,
	string). Changed TEBC to use eg 'TclNewIntObj(objPtr, i)' to avoid
	the function call in 'objPtr = Tcl_NewIntObj(i)' 
	(2) ExecEnv now stores two Tcl_Obj* pointing to the constants "0"
	and "1", for use by TEBC. 
	(3) slight reduction in cost of INST_START_CMD

	been done as part of the 1115904 bug fix on 2005-03-18.

	* generic/tclThreadTest.c:	Stop providing the phony package
	"Thread 1.0" when the [::testthread] command is defined.  It's
	never used by anything, and conflicts with loading the real
	"Thread" package.

2005-03-18  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileIncrCmd):	Corrected checks

	* generic/tclUtil.c (Tcl_PrintDouble):   
		Changed the signature of TclDoubleDigits so that it

		returns the signum via that pointer.  Added very
		hacky code to handle IEEE signed zeroes in Tcl_DoubleDigits.
		(It can't be done other than as a hack until C9x;

		Added output conversion of tagged NaN values.
	* generic/tclBinary.c (FormatNumber):
		Changed to allow [binary format] to handle NaN.
	* tests/binary.test (binary-60.1):
		Added a quick-n-dirty test to make sure that NaN's

	    Added code to ensure that 'ldexp' is never called with

	* tests/expr.test: Added tests for the smallest representible
	    value, and rounding between it and zero. (The tests reflect
	    current behaviour; plan is to change the specification of

	Add check for type of the framePtr->procPtr->bodyPtr
	passed to TclInitCompiledLocals and panic if

	    Replaced all uses of the native 'strtod' with a TclStrToD
	    routine that performs correct rounding and handles denormals.
	* generic/tclStrToD.c: (new file)
	    New scanning function for extracting 'double' from a string
	    that rounds correctly, and handles denormals and infinities.
	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.vc:
	    Added tclStrToD.c and the tommath routines that support it.

	These changes represent a partial implementation of TIP #132.
	Output conversion of floating point numbers, and proper handling

	* win/tclWinChan.c (FileCloseProc): Invoke TclpCutFileChannel() to
	remove a FileInfo from the thread local list before deallocating
	it.  This should have been done via an earlier call to
	Tcl_CutChannel, but I was running into a crash in the next call to
	Tcl_CutChannel during the IO finalization stage.

	DST rules and "best guess" at this year's Israeli rules.

2005-01-17  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c: fix for glob failure on Windows shares
	[Bug 1100542].

	* doc/pkgMkIndex.n: added documentation that 'pkg_mkIndex -lazy' is 
	not a good idea. [Bug 1101678]

2005-01-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/compile.test (compile-17.1): Document known issue with
	binding time of compiled command interpretations in [expr].

	* generic/tclIOUtil.c (TclFSFileAttrIndex): New helper function so
	that we don't need to hard-code attribute indexes. [Bug 1100671]

2005-01-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/string.n: Removed the term 'set' from the documentation of
	the [string trim] commands, as it caused confusion.

2005-01-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tcl.m4 (SC_PATH_{TCL,TK}CONFIG): Added code to detect the
	case when the --with-tcl/--with-tk arguments point to the config
	scripts themselves and not their directory. If this is the case,
	they now complain but keep working. [FRQ 951247]
	* unix/configure:	autoconf-2.57

	* unix/Makefile.in, unix/configure.in, unix/tcl.m4,
	* unix/tclConfig.sh.in, unix/dltest/Makefile.in:
	Remove ${DBGX}, ${TCL_DBGX} from Tcl build system [Patch 1081595].
	* unix/configure: regenerated

2005-01-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tclUnixFCmd.c (TclUnixCopyFile): Convert u_int to unsigned
	to make clashes with types in standard C headers less of a
	problem. [Bug 1098829]

2005-01-09  Joe English  <jenglish@users.sourceforge.net>

	* unix/tclUnixThrd.c, unix/tclUnixPort.h: Remove readdir_r()
	and related #ifdeffery (see #1095909).
	* unix/tcl.m4, unix/tclConfig.h.in: Don't check for HAVE_READDIR_R.
	* unix/configure: Regenerated.

2005-01-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* library/http/http.tcl (http::mapReply): Significant performance
	enhancement by using [string map] instead of [regsub]/[subst], and
	update version requirement to Tcl8.4. [Bug 1020491]

2005-01-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/lsearch.n, doc/re_syntax.n: Convert to other form of emacs

2005-01-05  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* tests/winDde.test: Fixed broken test result.

2005-01-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInt.h, generic/tclPort.h: Move the #include of
	tclConfig.h *first* before any reference to tcl.h so that the
	build configuration is loaded before the first reference to any
	system headers. Issue reported by Art Haas on tcl-core.

2005-01-04  Don Porter  <dgp@users.sourceforge.net>

	* tests/fCmd.test (fCmd-18.10):	Added notNetworkFilesystem constraint.
	[Bug 456665]

2004-12-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tcl.m4, win/configure: update MSVC CFLAGS_OPT to -O2, remove
	-Gs (included in -O2) and -GD (outdated).  Use "link -lib" instead
	of "lib" binary and remove -YX for MSVC7 portability.  Add
	-fomit-frame-pointer for gcc OPT compiles. [Bug 1092952, 1091967]
	Align LIBS_GUI with Tk head needs.

2004-12-29  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclDate.c: Regen
	* generic/tclGetDate.y (TclDatelex):
		Fixed a problem where a four-digit group with >=2 
		leading zeroes appeared to be a	two-digit group, leading to
		misinterpreting the time 0012 as 1200.	[Bug # 1090413]
	* library/clock.tcl: Added code to interpret correctly months
			     outside the range 01-12 as reduced modulo 12
			     with a corresponding adjustment to the year.
			     [Bug 1092789]
	* tests/clock.test: Added regression test cases for the above two
			    bugs.
	* unix/Makefile.in: Added --no-lines to the 'bison' command line 
	* win/Makefile.in:  to help constrain the number of diffs in a cvs
			    checkin.

2004-12-20  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c: moved TclInitCompiledLocals to tclProc.c 
	* generic/tclProc.c: new static InitCompiledLocals to allow for a
	single pass over the proc's arguments at proc load time (instead of
	two as previously). TclObjInterpProc() now allocates the
	compiledLocals on the tcl execution stack, using the new
	TclStackAlloc/Free functions.

2004-12-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInterp.c (Tcl_LimitSetTime, TimeLimitCallback):
	(TclLimitRemoveAllHandlers, TclInitLimitSupport): Set a timer
	event to trigger when the time limit runs out. All the time limit
	actually does is check to see if the time limit has been exceeded,
	but this is enough to fix [Bug 1085023].
	* generic/tclInt.h (struct Interp): Added a field to hold the token
	for the timer event handler associated with the current time limit.
	* generic/tclEvent.c (Tcl_UpdateObjCmd, Tcl_VwaitObjCmd): Add
	error message when limit exceeded.
	* tests/interp.test (interp-34.[89]): Check that time limits
	handle the two cases reported in [Bug 1085023]

	* generic/tclTimer.c (TclCreateAbsoluteTimerHandler): New internal
	function that allows setting a timer handler that will be
	triggered at (or after) a specific time instead of at some number
	of milliseconds in the future. This is a candidate for future
	exposure via a TIP.

	functions TclPushStackFrame and TclPopStackFrame that do the work
	of Tcl_PushCallFrame and Tcl_PopCallFrame, but using frames
	allocated in the execution stack - i.e., heap instead of
	C-stack. The core uses these two new functions exclusively; the
	old ones remain for backwards compat, as at least two popular
	extensions (itcl, xotcl) are known to use them.

2004-12-14  Don Porter  <dgp@users.sourceforge.net>

	* unix/configure.in:	Added special processing to remove "$U"
	from libraries in the LIBOBJS value.  This is an auto-make-ism
	we need to avoid.  [Bug 1081541]

	* unix/configure:	autoconf-2.57

2004-12-13  Don Porter  <dgp@users.sourceforge.net>

	* generic/tcl.h:	Restored extern "C" guards so that C++ code

	releases. [Bug 1082349].

	* generic/tclEncoding.c:	Plugged some memory leaks.  Thanks to

	[Bug 1075433].
	
2004-12-12  Miguel Sofer <msofer@users.sf.net>

	object [Bug 1084111] - thanks to Rolf Ade.

2004-12-12  Miguel Sofer <msofer@users.sf.net>

	* generic/tclObj.c (TclSetCmdNameObj): special handling for fully
	qualified command names (as in fix [Patch 456668]).

2004-12-11  Miguel Sofer <msofer@users.sf.net>

	* generic/tclInt.h:
	* generic/tclNamesp.c: converting the static function
	GetNamespaceFromObj() to MODULE_SCOPE TclGetNamespaceFromObj().  

2004-12-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tools/tcl.wse.in, unix/tcl.spec, win/README.binary, README: 
	* win/configure.in, unix/configure.in, generic/tcl.h: 
	Bumped version number to 8.5a3 to distinguish HEAD of CVS
	development from the recent 8.5a2 release.

2004-12-10  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c (TclInitCompiledLocals):
	* generic/tclCompile.h:
	* generic/tclInt.h:
	* generic/tclProc.c (TclObjInterpProc, TclCreateProc): optimised
	loops that initialise a proc's arguments and compiled local
	variables, removing tests from inner loops.

2004-12-10  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclInt.h: Move ensemble API decls here from tclNamesp.c

2004-12-09  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclNamesp.c (TclMakeEnsembleCmd, TclSetEnsemble*)
	(TclSetEnsemble*, TclFindEnsemble): Build an internal API for
	creating and manipulating ensembles; they can be deleted using the
	normal command-deletion API.

	* doc/Async.3: Reword for better grammar, better nroff and get the
	flag name right. (Reported by David Welton.)

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

	* tests/unixInit.test (2.1-4):	Added constraints so that when a
	value of TCL_LIBRARY is required for process initialization, we skip
	the tests that mess with that value.

2004-12-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	*** 8.5a2 TAGGED FOR RELEASE ***

	* unix/Makefile.in: add library/{tzdata,msgs} to dist target (kbk)

	* doc/foreach.n: Adjust tabs to be friendlier to some HTML
	converters. [Bug 1078760]

2004-12-06  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixNotfy.c (NotifierThreadProc): init numFdBits
	[Bug 1079286]

	* doc/error.n, doc/SaveResult.3, doc/Thread.3: minor nroff typos

2004-12-06  Don Porter  <dgp@users.sourceforge.net>

	* tests/safe.test:	Trim auto_path to improve performance [1080039]

	* tests/msgcat.test:	makeFile/removeFile cleanup [1079117]

2004-12-04  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclEncoding.c:	Different fix for [Bug 1077005].
	* generic/tclEvent.c:	Broke apart TclpSetInitialEncodings() on
	* generic/tclInt.h:	Windows into TclpSetInterfaces(), that is
	* unix/tclUnixInit.c:	fundamentally essential, and the initialization
	* win/tclWinInit.c:	of the system encoding, which is not.  Made
	the TclpSetInterfaces call part of TclInitSubsystems so it cannot be
	overlooked.

2004-12-03  Jeff Hobbs  <jeffh@ActiveState.com>

	* changes: updated for 8.5a2 release

2004-12-02  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclUtil.c (TclSetProcessGlobalValue):  Handle the case
	where a ProcessGlobalValue might be assigned to itself.

	* generic/tclEncoding.c (MakeFileMap):	Correct refcounting errors
	managing values returned by TclPathPart (with refCount of 1!) that
	led to a memory leak.  [Bug 1077474].

2004-12-02  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: fix and new tests for [Bug 1074671] to
	* tests/fileSystem.test:   ensure tilde paths are not returned
	specially by 'glob'.

2004-12-02  Kevin B. Kenny  <kennykb@acm.org>

	* win/Makefile.in: Added a 'sed' in the setting of ROOT_DIR_NATIVE
	to compensate for a bug in cygpath (at least version 1.36) that
	leaves a trailing backslash on the end of the converted path.

2004-12-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInterp.c (Alias,Target,Master): Rewrote these so that
	the aliases that refer to an interpreter are stored in a list and
	not a hashtable (which was only ever a convenience, and forced the
	use of a global mutex to generate keys!) [FRQ 1077210]
	* generic/tclNamesp.c (numNsCreated): Moved into thread-local
	storage to remove a global mutex. [FRQ 1077210]

2004-12-01  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclUtil.c (TclGetProcessGlobalValue):	Narrowed the scope
	of mutex locks.

	* generic/tclUtil.c:		Updated Tcl_GetNameOfExecutable() to
	* generic/tclEncoding.c:	make use of a ProcessGlobalValue for
	* generic/tclEvent.c:		storing the executable name.
	Added internal routines Tcl(Get|Set)ObjNameOfExecutable() to access
	that storage in Tcl_Obj, rather than string format.

	* unix/tclUnixFile.c:	Rewrote TclpFindExecutable() to use
	* win/tclWinFile.c:	TclSetObjNameOfExecutable to store the
	executable name it computes.

	* generic/tclInt.h:	Added internal stub entries for
	* generic/tclInt.decls: TclpFindExecutable and
	Tcl(Get|Set)ObjNameOfExecutable.

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

	* generic/tclCmdIL.c:	Retrieve executable name in Tcl_Obj form
	* win/tclWinPipe.c:	instead of string form.

	* unix/tclUnixTest.c:	Update [testfindexecutable] command to use
	new internal interfaces.

	* generic/tclEncoding.c:	Moved TclpSetInitialEncodings()
	call from Tcl_FindExecutable() into TclInitEncodingSubsystem().
	This is important on Windows where it establishes whether the
	"ascii" or "unicode" set of system routines will be used, and
	that needs to be done earlier to support filesystem operations.
	[Bug 1077005]

2004-12-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/winDde.test: Rewritten to use tcltest2 features more
	thoroughly (reducing the [catch] count!) and fix the problem with
	winDde-6.1 being out of synch with the implementation.

2004-11-30  Don Porter  <dgp@users.sourceforge.net>

	* library/init.tcl ([unknown]):	Restored the save/restore of
	the variables ::errorCode and ::errorInfo.  This is needed when
	the [::bgerror] command is auto-loaded (as it is by Tk).

	Patch 976520 reworks several of the details involved with
	startup/initialization of the Tcl library, focused on the
	activities of Tcl_FindExecutable().

	* generic/tclIO.c:	Removed bogus claim in comment that
	encoding "iso8859-1" is "built-in" to Tcl.
	
	* generic/tclInt.h:	Created a new struct ProcessGlobalValue,
	* generic/tclUtil.c:	routines Tcl(Get|Set)ProcessGlobalValue,
	and function type TclInitProcessGlobalValueProc.  Together, these
	take care of the housekeeping for "values" (things that can be
	held in a Tcl_Obj) that are global across a whole process.  That is,
	they are shared among multiple threads, and epoch and mutex
	protection must govern the validity of cached copies maintained
	in each thread.

	* generic/tclNotify.c:	Modified TclInitNotifier() to tolerate
	being called multiple times in the same thread.

	* generic/tclEvent.c:	Dropped the unused argv0 argument to
	TclInitSubsystems().  Removed machinery to unsure only one
	TclInitNotifier() call per thread, now that that is safe.
	Converted Tcl(Get|Set)LibraryPath to use a ProcessGlobalValue,
	and moved them to tclEncoding.c.
	* generic/tclBasic.c:	Updated caller.

	* generic/tclInt.h:	TclpFindExecutable now returns void.
	* unix/tclUnixFile.c:	
	* win/tclWinFile.c:
	* win/tclWinPipe.c:

	* generic/tclEncoding.c: Built new encoding search initialization
	on a foundation of ProcessGlobalValues, exposing new routines
	Tcl(Get|Set)EncodingSearchPath.  A cache of a map from encoding name
	to directory pathname keeps track of where encodings are available
	for loading.  Tcl_FindExecutable greatly simplified into just
	three function calls.  The "library path" is now misnamed, as its
	only remaining purpose is as a foundation for the default encoding
	search path.

	* generic/tclInterp.c:	Inlined the initScript that is evaluated
	by Tcl_Init().  Added verification after initScript evaluation
	that Tcl can find its installed *.enc files, and that it has
	initialized [encoding system] in agreement with what the environment
	expects.  [tclInit] no longer driven by the value of $::tcl_libPath;
	it largely constructs its own search path now, rather than attempt
	to share one with the encoding system.

	* unix/tclUnixInit.c:	TclpSetInitialEncodings factored so that a new
	* win/tclWinInit.c:	routine TclpGetEncodingNameFromEnvironment
	can reveal that Tcl thinks the [encoding system] should be, even
	when an incomplete encoding search path, or a missing *.enc file
	won't allow that initialization to succeed.  TclpInitLibraryPath
	reworked as an initializer of a ProcessGlobalValue.

	* unix/tclUnixTest.c:	Update implementations of [testfindexecutable],
	[testgetdefenc], and [testsetdefenc].

	* tests/unixInit.test:	Corrected tests to operate properly even
	when a value of TCL_LIBRARY is required to find encodings.

	* generic/tclInt.decls:	New internal stubs: TclGetEncodingSearchPath,
	TclSetEncodingSearchPath, TclpGetEncodingNameFromEnvironment.  These
	are candidates for public exposure by future TIPs.

	* generic/tclIntDecls.h:	make genstubs
	* generic/tclStubInit.c:
	
	* generic/tclTest.c:	Updated [testencoding] to use
	* tests/encoding.test:	Tcl(Get|Set)EncodingSearchPath.  Updated tests.

2004-11-30  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl: Corrected the regular expressions that match
	a time zone to allow for time zones specified as +HH or -HH.
	* tests/clock.test: Added regression test case for the above issue.
	Thanks to Rolf Ade for reporting this issue
	[http://wiki.tcl.tk/13094]
	* win/tclWinDde.c (Tcl_DdeObjCmd): Corrected a typo that caused a
	compilation failure on VC++.
	
2004-11-29  Andreas Kupries <andreask@activestate.com>

	* win/Makefile.in (install-libraries): Brought entry '2004-10-26
	  Don Porter (Tcl Modules)' into the windows world, actually the
	  win/configure buildsystem. The other windows buildsystems (.vc,
	  .bc) still have to be updated as well.

2004-11-26  Andreas Kupries <andreask@activestate.com>

	* win/tclWinDde.c (ExecuteRemoteObject): Removed bogus semicolon
	  found at the end of the header for the function definition,
	  terminating it early and preventing a compile. This is likely a
	  fix for '2004-11-25 Donal'. I have to conclude that it is also
	  unknown if the other changes to this file actually pass the
	  testsuite. Running testsuite ... They don't. winDde-6.1
	  fails. This is only a message discrepance, i.e. not too
	  bad. Leaving resolution of that to Pat and Donal.

2004-11-26  Don Porter  <dgp@users.sourceforge.net>

	* library/auto.tcl (tcl_findLibrary):   Made sure the uniquifying
	operations on the search path does not also normalize.  [Bug 1072136]

2004-11-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/configure.in: Simplify the code to check for correctness of
	strstr, strtoul and strtod.
	* unix/tcl.m4 (SC_TCL_CHECK_BROKEN_FUNC): Split a complex stanza
	out of configure.in into its own function. Also force it to do the
	right thing with cacheing of results of AC_TRY_RUN to deal with
	issue raised in [Patch 1073524]

	* doc/foreach.n: Added simple example. [FRQ 1073334]

2004-11-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclProc.c (TclObjInterpProc):	    Make it so that only
	* generic/tclIndexObj.c (Tcl_WrongNumArgs): [proc] instances do
	* tests/indexObj.test (indexObj-5.7):	    quoting of their first
	arguments, so keeping [Bug 942757] fixed and making [Bug 1066837]
	be fixed as well. Done with a load of #ifdef-ery because this hack
	is so ugly nobody should keep it around once Itcl's fixed.

2004-11-25  Reinhard Max  <max@suse.de>

	* tests/tcltest.test: The order in which [glob] returns the file
	names is undefined, so tests should not depend on it.
	
2004-11-25  Zoran Vasiljevic <vasiljevic@users.sf.net>

	* doc/Thread.3:
	* doc/Notifier.3: Added changes from the core-8-4-branch

2004-11-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/dde.n: Synchronized the documentation of the commands with
	the header of the docs and what the package actually does. Thanks
	to Andreas Kupries for spotting this.
	* win/tclWinDde.c (Tcl_DdeObjCmd): Much cleanup of argument
	parsing code.

2004-11-24  David Gravereaux <davygrvy@pobox.com>

	* generic/tclPort.h: Relative include of tclWinPort.h returned
	as it was requiring me set -I$(tcl_root)/win for my extensions
	that need to include tclInt.h and doesn't appear to serve any
	purpose for windows builds.

2004-11-24  Kevin B. Kenny  <kennykb@acm.org>

	* unix/tcl.m4 (SC_ENABLE_THREADS): Corrected bad check for
	3-argument readdir_r [Bug 1001325].
	* unix/configure: Regenerated.
	* unix/tclUnixNotfy.c: Corrected all uses of 'select' to
	manage their masks using the FD_CLR, FD_ISSET, FD_SET, and
	FD_ZERO macros rather than bit-whacking that failed under
	Solaris-Sparc-64.  [Bug 1071807]
	* win/tclWinInit.c (TclpInitLibraryPath): Removed unused
	vars 'pathc' and 'pathv' that caused compilation problems
	on VC++ with --enable-symbols.
	
2004-11-24  Don Porter  <dgp@users.sourceforge.net>

	* unix/tcl.m4 (SC_ENABLE_THREADS):	Corrected failure to determine
	the number of arguments for readdir_r on SunOS systems.  [Bug 1071701]

	* unix/configure:	autoconf-2.57

	* generic/tclCmdIL.c (InfoVarsCmd):	Corrected segfault in new
	* tests/info.test (info-19.6):	trivial matching branch [Bug 1072654]

2004-11-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tools/man2html.tcl, tools/man2html1.tcl: Update to use Tcl 8.4.
	* tools/man2html2.tcl: Fix broken .SS handling.

2004-11-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/Makefile.in: Add (commented-out) code to integrate tclConfig.h
	into the dependency tree and 'make distclean'. [Bug 1068171]

	* generic/tclResult.c (Tcl_AppendResultVA): Remove call to
	Tcl_GetStringResult to speed up repeated calls to Tcl_AppendResult
	with the side effect that code that wants to access interp->result
	should always call Tcl_GetStringResult first. See [Patch 1041072]
	discussion for more details.

2004-11-22  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_TCL_64BIT_FLAGS): Define HAVE_TYPE_OFF64_T
	only when off64_t, open64(), and lseek64() are defined.
	IRIX 5.3 is known to not include an open64 function.
	[Bug 1030465]

2004-11-22  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_ENABLE_THREADS): Check for a 2
	argument version of readdir_r that is known to
	exists under IRIX 5.3.
	* unix/tclUnixThrd.c (TclpReaddir): Use either
	2 arg or 3 arg version of readdir_r.
	[Bug 1001325]

2004-11-22  Don Porter  <dgp@users.sourceforge.net>

	* unix/tclUnixInit.c (TclpInitLibraryPath):	Purged dead code that
	* win/tclWinInit.c (TclpInitLibraryPath):	used to extend the
	"library path".  Search path construction for init.tcl is now done
	within the [tclInit] proc.

	* generic/tclInterp.c:	Restored several directories to the search
	* tests/unixInit.test:	path used to locate init.tcl within [tclInit].
	This change does not restore any directories to the encoding search
	path, so should still avoid the price of an unreasonably large number
	of filesystem accesses during encoding initialization at startup
	[Bug 976438]

2004-11-22  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: fix and new test for [Bug 1043129] in
	* tests/fileSystem.test: the treatment of backslashes in file
	join on Windows.

2004-11-21  Don Porter  <dgp@users.sourceforge.net>

	* doc/AddErrInfo.3:	Typo corrections (Thanks Daniel South).
	* doc/interp.n:

2004-11-19  Don Porter  <dgp@users.sourceforge.net>

	* doc/AddErrInfo.3:	Docs for Tcl_(Get|Set)ReturnOptions.  [TIP 227]

	* doc/AddErrInfo.3:
	* doc/Async.3:		Documentation updates to replace references
	* doc/BackgdErr.3:	to global variable ::errorInfo and ::errorCode
	* doc/SaveResult.3:	and to the ::bgerror command with references
	* doc/after.n:		to their preferred replacements, the
	* doc/bgerror.n:	-errorinfo and -errorcode return options,
	* doc/error.n:		the Tcl_*InterpState routines, and the
	* doc/exec.n:		[interp bgerror] command.

	* doc/interp.n:
	* doc/return.n:
	* doc/tclvars.n:
	* doc/update.n:

	* tests/unixInit.test:	Removed "knownBug" constraints to prompt
	bug fixing before 8.5a2 release.

2004-11-19  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Makefile: 
	* unix/configure.in: 
	* unix/tclUnixInit.c (MacOSXGetLibraryPath): changed detection
	of tcl framework build when determining tclLibPath from overloaded
	TCL_LIBRARY to configuration define TCL_FRAMEWORK. [Bug 1068088]

	* unix/configure: autoconf-2.57
	* unix/tclConfig.h.in: autoheader-2.57

2004-11-18  Don Porter  <dgp@users.sourceforge.net>

	* doc/SaveResult.3:	Documentation for Tcl_*InterpState (TIP 226).

	* generic/tclEvent.c (HandleBgErrors):	Simplified program flow.

	* tests/basic.test:	Updated functional (not testing) uses of
	* tests/io.test:	[bgerror] to make use of [interp bgerror].
	* tests/socket.test:
	* tests/timer.test:

	* tests/interp.test (interp-36.*):	[interp bgerror] tests.

	* generic/tclInterp.c:	Corrected [interp bgerror] error messages.

2004-11-18  Reinhard Max  <max@suse.de>

	* unix/tcl.m4 (SC_CONFIG_MANPAGES): Applied an improved version of
	* unix/configure.in:                patch #996085, that introduces
	* unix/Makefile.in:                 --enable-man-suffix.

	* unix/installManPage:              added
	* unix/mkLinks.tcl:                 removed
	* unix/mkLinks:                     removed
	* unix/configure:                   generated

	* unix/Makefile.in:                 Don't install tclConfig.h .

2004-11-17  Don Porter  <dgp@users.sourceforge.net>

	* unix/configure.in:	The change below reveals that the public
	data type Tcl_StatBuf relies on config information.  For now,
	disabled the use of the tclConfig.h file until its full impact
	on Tcl's interface can be assessed.

	* unix/configure:	autoconf-2.57

	* generic/tcl.h:	Moved the #include "tclConfig.h" out of
	* generic/tclInt.h:	tcl.h.  The config settings are not part of
	* generic/tclPort.:	the public interface, and having it there
	breaks compiled against uninstalled Tcl and extensions using
	autoconf-2.5*.

2004-11-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixChan.c (TtySetOptionProc): fixed crash configuring
	-ttycontrol on a channel. [Bug 1067708]

2004-11-16  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclIOUtil.c (TclFSEpochOk):	There were two code paths
	via which the thread copy of filesystemEpoch could be synched with
	the master copy, but only one kept the filesystem list cache up
	to date.  Fix routes everything through  a single code path.
	[Bug 1035775].

2004-11-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Stop architecture flags to 'ld'
	from getting lost when [load] is disabled. [Bug 1016796]

2004-11-16  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tcl.h:
	* unix/configure.in: changed HAVE_CONFIG_H to HAVE_TCL_CONFIG_H.

	* unix/configure: autoconf-2.57

2004-11-15  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.h:	Added comment warning that the old
	ERR_IN_PROGRESS and ERROR_CODE_SET flag values should not be re-used
	for the sake of those extensions that have accessed them.

	* generic/tclCmdMZ.c (Tcl_TraceObjCmd): Fixed Bug 1065378 which failed
	* tests/trace.test (trace-33.1):        to permit a variable trace
	created with [trace variable] to be destroyed with [trace remove].
	Thanks to Keith Vetter for the report.

2004-11-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/tclvars.n: Added section to documentation on global
	variables that are specific to tclsh and wish. [Patch 1065732]

2004-11-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclEncoding.c (TableFromUtfProc): correct crash
	condition when TCL_UTF_MAX == 6. [Bug 1004065]

2004-11-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/interp.n: Basic documentation of the TIP#221 API.

2004-11-12  Don Porter  <dgp@users.sourceforge.net>

	TIP #221 IMPLEMENTATION
	* generic/tclBasic.c:	Define [::tcl::Bgerror] in new interps.
	* generic/tclEvent.c:	Update Tcl_BackgroundError to make use
				of the registered [interp bgerror] command.

	* generic/tclDictObj.c:	Update callers.
	* generic/tclIOGT.c:
	* generic/tclTrace.c:

	* generic/tcl.decls:	Stubs for Tcl_(Get|Set)ReturnOptions.
	* generic/tclInt.h:	Drop old private declarations.
	* generic/tclResult.c:	Tcl_*ReturnOptions implementations.
	* generic/tclCmdAH.c:	Update callers.
	* generic/tclMain.c:

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

	* unix/tclAppInit.c:	Removed tclConfig.h #include, now that tcl.h
				takes care of it for us.

	* generic/tclInt.h:	Moved verification of ptrdiff_t typedef from
	* generic/tclExecute.c: multiple .c files into one common header where
	* generic/tclVar.c:	it is verifiably after tclConfig.h inclusion.

2004-11-12  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tcl.h:
	* generic/tclInt.h:
	* unix/Makefile.in: include tclConfig.h from tcl.h and install it
	as a public header. Normalized compiler include path order to 
	-I${BUILD_DIR} -I${UNIX_DIR} -I${GENERIC_DIR}.

	* unix/dltest/Makefile.in: add ${BUILD_DIR}/.. to include path
	to pick up tclConfig.h.

	* unix/tclUnixInit.c: moved check for HAVE_CFBUNDLE define after
	#include "tclInt.h" to ensure tclConfig.h has been included.

2004-11-12  Reinhard Max  <max@suse.de>

	* unix/config.h.in:
	* unix/tclConfig.h.in:	renamed

	* unix/Makefile.in:	Completed support for config header,
	* unix/configure.in:	fixed building outside of the unix dir,
	* unix/tclAppinit.c:	and reflected the name change of config.h.
	* generic/tclInt.h:

	* unix/configure:       generated

2004-11-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/config.h.in:	Allow configure to put all the C #defs into
	* unix/configure.in:	a file (called config.h) so that Unix builds
	* unix/tcl.m4:		now take far fewer lines of scrollback to
	* unix/Makefile.in:	proceed (making it less likely that any errors
	* generic/tclInt.h:	or warnings will get missed).
	* unix/tclAppInit.c:	Part of the TIP#34 upgrades.

	* unix/tcl.m4, unix/tclUnixPort.h: Check for pthread_attr_get_np
	in <pthread.h> before forcing the use of <pthread_np.h> to make
	things work on NetBSD 2.0.  [Bug 1064882]

	* doc/binary.n, doc/upvar.n: More minor fixes.

2004-11-12  Daniel Steffen  <das@users.sourceforge.net>

	* doc/CrtChannel.3:
	* doc/Interp.3:
	* doc/Limit.3:
	* doc/binary.n:
	* doc/dict.n:
	* doc/tm.n:
	* doc/upvar.n: fixed *roff errors uncovered by running 'make html'.

	* tools/tcltk-man2html.tcl: added faked support for bullet point
	lists, i.e. *nroff ".IP \(bu" syntax.

2004-11-11  Daniel Steffen  <das@users.sourceforge.net>

	* tests/fCmd.test:
	* unix/tclUnixFCmd.c (TraverseUnixTree): added option to rewind()
	the readdir() loop whenever the source hierarchy has been modified
	by traverseProc (e.g. by deleting files); this is required to ensure
	complete traversal of the source hierarchy on certain filesystems
	like HFS+. Added test for failing recursive delete on Mac OS X that
	was due to this. [Bug 1034337]

	* generic/tclListObj.c (Tcl_ListObjReplace): use memmove() instead
	of manual copy loop to shift list elements. Decreases time spent in
	Tcl_ListObjReplace() from 5.2% to 1.7% of overall runtime of
	tclbench on a ppc 7455 (i.e. 200% speed increase). [Patch 1064243]

	* generic/tclHash.c: hoisted some constant pointer dereferences out
	of loops to eliminate redundant loads that the gcc optimizer didn't
	deal with. Decreases time spend in Tcl_FindHashEntry() by 10% over a
	full run of the tcl testuite on a ppc 7455. [Patch 1064243]

	* tests/fileName.test:
	* tests/fileSystem.test:
	* tests/io.test:
	* tests/msgcat.test:
	* tests/tcltest.test:
	* tests/unixInit.test: fixed bugs causing failures when running
	tests with -tmpdir arg not set to working dir.

	* macosx/Makefile: corrected path to html help inside framework.
	Prevent parallel make from building several targets at the same
	time.

	* macosx/tclMacOSXFCmd.c (struct fileinfobuf): force struct to be
	packed to prevent failures when builing with -malign=natural.

2004-11-10  Andreas Kupries <andreask@activestate.com>

	* unix/tclUnixChan.c: [Bug 727786]. Exterminated the code marked
	  DEPRECATED. This code has not been used in over a year now, and
	  we have no complaints.

2004-11-08  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinPipe.c: The pipe channel driver now respects
	the -blocking option when closing is the same way the UNIX
	side works.  This is to avoid a hung shell when exiting due
	to open pipes that refuse to close in a graceful manner.
	* doc/open.n: Added a note about -blocking 0 and lack of
	exit status as it had never been documented. [Bug 947693]

	***POTENTIAL INCOMPATIBILITY***

	Scripts that use async pipes on windows, must (like the
	UNIX side) set -blocking to 1 before calling [close] to
	receive the exit status.

2004-11-07  David Gravereaux <davygrvy@pobox.com>

	* tests/winFile.test: added contraint to winFile-4.0 to prevent
	it being run on NT4 [Bug 981829]

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

	* tests/reg.test: Major reorganization so that this file is much
	easier for a normal Tcl maintainer to comprehend.  The test flags
	are still very cryptic, but they appear to have to be that way.
	The number of skipped tests has increased, but now the skipped
	tests have much more meaningful content.

	* tests/tm.test (genpaths): Add a [file normalize] so we pick up
	Windows drive letters, etc. [Bug 1053568]

2004-11-04  Don Porter  <dgp@users.sourceforge.net>

	* changes:	Updates toward an 8.5a2 release.

2004-11-03  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl (FreeScan): Fixed a bug where scanning
	"Monday" with a base time other than midnight incorrectly carried
	the base time forward.

	* test/clock.test (clock-33.{5,5a}): Made the test failure more
	informative.

	* tests/clock.test (clock-34.{28,44,45,46}): Removed 'knownBug'
	constraints from tests that no longer fail.

	Thanks to Don Porter for reporting these.

2004-11-03  David Gravereaux <davygrvy@pobox.com>

	* generic/tcl.h:		Moved the preprocessor logic
	* generic/tclDecls.h:		from tclInt.h of setting the
	* generic/tclInt.h:		TCL_STORAGE_CLASS macro to the
	* generic/tclIntDecls.h:	tcl*Decls.h files now that no
	* generic/tclIntPlatDecls.h:	use of EXTERN is left in tclInt.h.
	* generic/tclPlatDecls.h:	Proto for Tcl_Main moved in tcl.h
	* win/tclWinPort.h:		to prior the inclusion of the Stubs
	headers as they are now resetting TCL_STORAGE_CLASS.  Removed
	extrainious reset from tclWinPort.h.  [Patch 1055668]

	* generic/tclCompile.h: Removed	extrainious reset of
	TCL_STORAGE_CLASS missed in my last edit.

2004-11-03  Don Porter  <dgp@users.sourceforge.net>

	* library/init.tcl ([unknown]):	Corrections to the 2004-10-25 mods
	to Aunt ??? in [unknown].  Flaws revealed by Itcl test suite, which
	still apparently relies on this brokenness.  Also added comment
	suggesting the error message that any code using this hack *ought*
	to receive in reply.

	* generic/tclTrace.c (TclCallVarTraces):  Improved ability to debug
	* tests/incr-old.test (incr-old-2.6):	  errors during variable
	* tests/incr.test (incr-{1,2}.28):	  traces by preserving the
	* tests/set.test (set-{2,4}.4):		  -errorinfo data.
	* tests/trace.test (trace-33.1):	  [Bug 527164]

2004-11-02  David Gravereaux <davygrvy@pobox.com>

	* generic/tclInt.h: added a check for #ifdef __cplusplus around
	the #define of MODULE_SCOPE.  About the only time it would be
	problem is when someone is statically linking to Tcl and accessing
	internals from a C++ file and has name mangling issues from the
	lack of "C" after 'extern' [Patch 1055668].
	* generic/tclCompile.h: Exchanged use of the EXTERN macro to the
	new MODULE_SCOPE macro.  Lowered exported internals count by 35.
	[Patch 1055668]
	* win/tclWinInt.h:
	* win/tclWinPort.h: exported internals dropped by a count of 14.
	* generic/tclFileSystem.h: Added use of MODULE_SCOPE on protos.
	* generic/tclRegexp.h: manipulating TCL_STORAGE_CLASS unnecessary.

2004-11-02  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:		Corrected some misleading
	* tests/tcltest.test (tcltest-26.1,2):	displays of ::errorInfo and
	::errorCode information when the -setup, -body, and/or -cleanup scripts
	return an unexpected return code.  Thanks to Robert Seeger for the
	fix. [RFE 1017151].

2004-11-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): Improved version of
	the NaN fix from Miguel Sofer. [Bug 761471]

2004-11-02  Kevin Kenny  <kennykb@acm.org>

	* library/tzdata/America/Cuiaba: Change to DST rules for
	* library/tzdata/America/Havana: autumn of 2004. 
	[ftp://elsie.nci.nih.gov/pub/tzdata2004g.tar.gz]

	* tools/tclZIC.tcl: Updated to be compatible with recent
	changes in library/clock.tcl.

2004-11-02  Vince Darley  <vincentdarley@users.sourceforge.net>

	* win/tclWinFile.c: Simplify TclpUtime to use Tcl_FSGetNativePath, 
	and add comments.

2004-11-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInt.h: Change uses of EXTERN to MODULE_SCOPE (defined
	in this file too to be 'extern' if not overridden) as nothing
	declared in tclInt.h is supposed to be visible outside the Tcl
	core. If there *is* anything that extensions are actually using,
	we can open this up later on. [Patch 1055668]

	* doc/CrtChannel.3 (Tcl_GetChannelMode): Add synopsis. [Bug 1058446]

2004-11-01  Kevin B. Kenny  <kennykb@acm.org>

	* win/tclWinFile.c (FromCTime, TclpUtime): Replaced a call to the
	Posix 'utime' function with calls to Windows-API equivalents, to
	avoid a bug where the VC++ versions misconvert times across a
	Daylight Saving Time boundary.	[Bug 926106]
	* win/tclWinInt.h (TclWinProcs):
	* win/tclWin32Dll.c (asciiProcs, unicodeProcs): Removed now-unused
	reference to 'utime'.
	* tests/cmdAH.test (cmdAH-24.12): Added test case for the
	above bug.

2004-11-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): Make INST_EQ and
	friends handle NaN correctly in all cases. [Bug 761471]

	* generic/tclNamesp.c (NamespaceInscopeCmd): Make the error
	message generation the same as in NamespaceEvalCmd().
	(Tcl_Import): Rationalized to use Tcl_EvalObjv().

2004-10-31  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/io.test (io-40.3): Convert umask2 test constraint into a
	form that most people will be able to satisfy.

	* tests/cmdAH.test (cmdAH-8.45): Removed broken test constraint.
	It didn't do what it was intended to do, and it implied the other
	correct constraint. [Bug 1053908]

	* generic/tclCmdIL.c (InfoGlobalsCmd): 
	* tests/info.test (info-8.4): Strip leading global-namespace
	specifiers from the pattern argument. [Bug 1057461]

2004-10-30  Kevin Kenny  <kennykb@acm.org>

	* generic/clock.c: Replaced WIN32 macro with __WIN32__.
	[Bug 1054357].  Thanks to David Gravereaux for the patch.
	* win/tclWinFile.c: Removed a long-standing bug that causes
	incorrect conversion between file time and UTC time if
	the file time is recorded in a different Daylight Saving Time
	status than the current one. [Bug 926106]

2004-10-29  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:	Correct reaction to errors in the
	obsolete processCmdLineArgsHook.	[Bug 1055673]
	* library/tcltest/pkgIndex.tcl:	Bump to tcltest 2.2.7
	* unix/Makefile.in:
	* tests/all.tcl:	Update to use [tcltest::configure].

2004-10-29  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* library/tm.tcl (::tcl::tm::*): Use the core proc engine to
	generate the wrong-num-args error messages for the path ensemble.

	Ensembles can now (sometimes) rewrite the error messages of their
	subcommands so they appear more like the arguments that the user
	passed to the ensemble. Below is a description of changes involved
	in doing this.

	* tests/namespace.test (namespace-50.*): Tests of ensemble
	subcommand error message rewriting.
	* generic/tclProc.c (TclObjInterpProc): Make procedures implement
	their wrong-num-args message using Tcl_WrongNumArgs instead of
	something baked-at-home.
	* generic/tclNamesp.c (TclIsEnsemble, NsEnsembleImplementationCmd): 
	Added test of ensemble-hood (available to rest of core) and made
	ensembles set up the rewriting for Tcl_WrongNumArgs to take
	advantage of.
	* generic/tclInt.h (Interp.ensembleRewrite): Extra fields.
	* generic/tclIndexObj.c (Tcl_WrongNumArgs): Add knowledge of what
	is going on in ensembles' command rewriting so this command can
	generate the right error message itself.
	* generic/tclBasic.c (Tcl_CreateInterp, TclEvalObjvInternal):
	Added code to initialize (as empty) the rewriting fields and reset
	them when we leak outside an ensemble implementation.

2004-10-28  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (INST_START_CMD):
	* tests/execute.test (execute-8.3): fix for execution stack
	corruption [Bug 1055676]. Credit dgp for detective work and fix. 

2004-10-27  Don Porter  <dgp@users.sourceforge.net>

	* tests/socket.test (socket-13.1):      Balanced [makeFile] and
	[removeFile] commands.

	* tests/clock.test:	Correct duplicate test names.
	* tests/namespace.test:
	* tests/string.test:
	* tests/io.test (io-50.4):	Use namespace variables.

2004-10-27  David Gravereaux <davygrvy@pobox.com>

	* generic/tclInt.decls:	  The following 9 functions were moved from
	* generic/tclInt.h:	  tclInt.h to the private/int Stubs table for
	* generic/tclIntDecls.h:  use by the test suite.  As tclTest.obj is
	* generic/tclStubInit.c:  linked to the shell, these functions need
	"blessed" status so as to always be exported from the library. Being
	placed in the Stubs table guarantees this [Bug 1054748]:
		TclpObjRemoveDirectory,	TclpObjCopyDirectory,
		TclpObjCreateDirectory,	TclpObjDeleteFile,
		TclpObjCopyFile,	TclpObjRenameFile,
		TclpObjStat,		TclpObjAccess,
		TclpOpenFileChannel

	* tests/registry.test:	Fixed test files to load the correct
	* tests/winDde.test:	registry and dde packages by using the info
	* win/Makefile.in:	from makefiles to tell tcltest where to load
	* win/makefile.vc:	them from.  This avoids grabbing the wrong
	package from $auto_path which might be the install point rather than
	the dev location.  Kudos to Jennifer Hom for adding -load and
	-loadfile to the tcltest package. [Bug 926088]

	* win/tclWinThrd.c (TclFinalizeLock): release the critical section
	before deleting it. [Bug 731778]

	* generic/tcl.h: Removed the file level 'extern "C" {' and the
	coresponding closing block as it serves no purpose given that all
	the function prototypes have the proper extern usage already.

	* unix/tclAppInit.c:	When built as tcltest, TclThread_Init was
	* win/tclAppInit.c:	getting called twice.  First by
	Tcltest_Init, then again in Tcl_AppInit.  The call from Tcl_AppInit
	is now removed.

2004-10-27  Andreas Kupries <andreask@activestate.com>

	* tests/tm.test:  Expanded on the testsuite entered by Donal.
	* library/tm.tcl: Even found bugs, these have been corrected.

2004-10-26  Kevin Kenny <kennykb@acm.org>

	* tests/format.test (format-19.1): Additional regression test for
					   Bug 868489.

2004-10-27  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/*.n: Many small general documentation fixes.

2004-10-26  David Gravereaux <davygrvy@pobox.com>

	* generic/tclPipe.c (TclCleanupChildren): bad cast of resolvedPid
	caused PIDs on win95 to go negative.  winpipe-4.2 brought this to
	the surface.  Fixed with sprintf in place of TclFormatInt.  Thanks
	to hgiese [Patch 767676]

2004-10-26  Andreas Kupries <andreask@activestate.com>

	* library/tm.tcl (::tcl::tm::Defaults): Added a second [file
	  dirname] around the location of the executable. This fixes [Tcl
	  SF Bug 1038705]. Instable of a bogus "foo/bin/lib" we now have
	  the correct "foo/lib" as a base path for modules.

2004-10-26  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclParse.c (Tcl_SubstObj):	Fix for failed subst-12.3 test.
	* tests/subst.test (subst-12.3-5):      More tests for Bug 1036649.

	* unix/Makefile.in (install-libraries): Updated the installation
	of the http, msgcat, and tcltest packages to install as Tcl Modules
	on Unix systems.  Other platform Makefiles still need updating.
	[Patch 1054370]

	* tests/basic.test:	Added missing constraints.
	* tests/compile.test:
	* tests/fileSystem.test:

	* tests/init.test (init-2.8):	Updated to not rely on http package.

2004-10-26  Miguel Sofer <msofer@users.sf.net>

	* generic/tclInt.h:
	* generic/tclVar.c: removed more direct references to the VAR
	flags, replaced with access macros.

2004-10-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/expr.n: Clarified that non-num/non-bool literals require
	quoting. [Bug 1027849]. Also listed booleans as acceptable values.

2004-10-26  Kevin B. Kenny <kennykb@acm.org>

	* library/clock.tcl (FreeScan): Fixed a bug that caused relative
	days of the week in free-form [clock scan] to be evaluated in the
	wrong time zone.
	* tests/clock.test (clock-31.[456]): Made sure that there
	isn't an env(TZ) or env(TCL_TZ) lying around that will
	override the time zone that we're trying to establish with
	the simulated registry.
	Both problems reported as [Bug 1054101].

2004-10-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/string.n (map): Rewrote to clarify that we don't just map
	single characters. [Bug 1048005]
	* doc/info.n (procs): Clarified that the pattern argument may have
	namespace separators in it. [Bug 1047928]

	* tests/cmdAH.test (cmdAH-8.45): Simplify in the hope that the
	reasons for [Bug 1053908] will become clearer.

2004-10-25  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c (IllegalExprOperandType,TclExecuteByteCode):
	Removed several DECACHE_INFO/CACHE_INFO pairs that are no longer
	needed for protection because routines like Tcl_SetErrorCode() and
	Tcl_AddErrorInfo() can no longer re-enter bytecode execution.

	* generic/tclResult.c (TclProcessReturn): Bug fix.  Be sure that
	a missing -errorinfo option when code == TCL_ERROR causes the
	errorInfo field to get reset.

	* tests/thread.test (thread-4.4): Test depended on a ::errorInfo
	value initialized to "".  Added code to test to setup that requirement.

	* library/auto.tcl	Purged Tcl's script library of all
	* library/clock.tcl	remaining references to global vars
	* library/init.tcl	::errorInfo and ::errorCode.

	* generic/tclMain.c (Tcl_Main):	Updated to make use of
	TclGetReturnOptions instead of ::errorInfo variable.

	* generic/tclInterp.c (tclInit): Bug fix.  Access dict variables
	with [dict get], not array syntax.  

2004-10-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/tm.test: Rewrote the tests to actually perform syntax
	checks on the public API. Added a new test (currently failing) to
	indicate that the test suite is not complete yet.
	* library/tm.tcl (path): Rewrote to turn this command into an
	ensemble to make it faster and simpler.

2004-10-24  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCmdIL.c:
	* generic/tclExecute.c:
	* generic/tclInt.h:
	* generic/tclTrace.c: defined new macros to get/set the flags of 
	variables. The only files that still access the flag values
	directly are tclCompCmds.c, tclCompile.c, tclProc.c and tclVar.c

2004-10-24  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_LogCommandInfo,Tcl_AddObjErrorInfo):
	Shift the initialization of errorCode to NONE to more central
	location.

	* generic/tclEvent.c (BgError,Tcl_BackgroundError,HandleBgErrors):
	Rewrite to build on the new TclGet/SetReturnOptions routines.

	* generic/tclResult.c (TclGetReturnOptions): Add call to
	Tcl_AddObjErrorInfo to be sure error fields are initialized.

	* generic/tclResult.c (TclTransferResult):
	Rewrite to build on the new TclGet/SetReturnOptions routines.

2004-10-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/tm.n: Tightened up the documentation.
	* tests/tm.test: Created (with partially dummy content) so TIP#189
	can be marked Final.

	* generic/tclNamesp.c (NsEnsembleImplementationCmd): Make
	ensembles cut their implementations out of error traces. This is
	the right thing to do more often than not.

2004-10-22  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl: Fixed a typo where the fallback time zone
	became ::localtime instead of :localtime.  Fixed a bug where
	time zone names containing hyphens could not be loaded.
	* tests/clock.test: Added regression test cases that covers
	both bugs.
	Thanks to Todd M. Helfter <tmh@jumpgate.itsp.purdue.edu> for
	finding these bugs.

2004-10-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclExecute.c (TclCompEvalObj, Tcl_ExprObj): 
	* generic/tclProc.c (TclProcCompileProc): Always call object
	freeIntRepProc's in the same way.

2004-10-22  Miguel Sofer <msofer@users.sf.net>

	* generic/tclVar.c: fixed bug in commit of 2004-07-23, which was
	causing a leak of Proc structures and failure of compile-12.1. Two
	lines were 'zombies' from the previous way localVarNames
	worked. Credit dgp for finding this.

2004-10-21  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.h (Interp):
	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
	* generic/tclResult.c (GetKeys,ReleaseKeys,etc.):
	Moved the key values of the return options dictionary out of
	private fields of the Interp struct and into thread-static
	values managed in tclResult.c.

	* generic/tclCmdAH.c (Tcl_CatchObjCmd, Tcl_ErrorObjCmd):
	Updated to call the new TclGet/SetReturnOptions routines to do
	much of their work.

	* generic/tclInt.h (TclGetReturnOptions,TclSetReturnOptions):
	* generic/tclResult.c (TclGetReturnOptions,TclSetReturnOptions):
	New utility routines to get/set the return options of an interp.
	Intent is that these routines will be converted to public routines
	after TIP approval.

	* generic/tclCmdMZ.c (TclProcessReturn,TclMergeReturnOptions):
	* generic/tclResult.c (TclProcessReturn,TclMergeReturnOptions):
	Move internal utility routines from tclCmdMZ.c to tclResult.c.

	* generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp):
	* generic/tclResult.c (TclTransferResult):	Rework so that
	iPtr->returnOpts can be NULL when there are no special options.

	* generic/tclResult.c (TclRestoreInterpState):  Plug potential
	memory leak.

2004-10-21  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclBasic.c: Various changes to [clock format] that,
	* generic/tclClock.c: together, make it roughly twice as fast
	* generic/tclInt.h:   while all tests in the test suite
	* library/clock.tcl:  continue to pass.

2004-10-20  Andreas Kupries <andreask@activestate.com>

	* win/Makefile.in (install-msgs):   Fixed a problem with the
	* win/Makefile.in (install-tzdata): installation of timezone data
	  and message catalogs. They used the installed tcl library
	  directory, not the source library. Before it was installed.
	  Switched to source lib dir. Thanks to Kevin for the help in
	  figuring this out.

2004-10-20  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclThreadTest.c (ThreadEventProc):	Corrected subtle
	bug where the returned (char *) from Tcl_GetStringResult(interp)
	continued to be used without copying or refcounting, while
	activity on the interp continued.  That's not safe, and recent
	changes demonstrated the lack of safety with failing tests
	thread-4.3 and thread-4.5.

2004-10-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclDictObj.c (DictWithCmd): Make sure all paths (that
	are not themselves error paths) do not lose the result code.

2004-10-19  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.h (Tcl*InterpState):		New internal routines
	* generic/tclResult.c (Tcl*InterpState):	TclSaveInterpState,
	TclRestoreInterpState, and TclDiscardInterpState are superior
	replacements for Tcl_(Save|Restore|Discard)Result.  Intent is that
	these routines will be converted to public routines after TIP approval.
	Interfaces for these routines were shamelessly stolen from Itcl.

	* generic/tclBasic.c (TclEvalObjvInternal):
	* generic/tclDictObj.c (DictUpdateCmd, DictWithCmd):
	* generic/tclIOGT.c (ExecuteCallback):
	* generic/tclTrace.c (Trace*Proc,TclCheck*Traces,TclCallVarTraces):
	Callers of Tcl_*Result updated to call the new routines.  The
	calls were relocated in several cases to perform save/restore
	operations only when needed.

	* generic/tclEvent.c (HandleBgErrors):
	* generic/tclFCmd.c (CopyRenameOneFile):
	Calls to Tcl_*Result that were eliminated because they appeared
	to serve no useful purpose, typically saving/restoring an error
	message, only to throw it away.

2004-10-18  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
	* generic/tclCmdAH.c (Tcl_CatchObjCmd):
	* generic/tclCmdMZ.c (TclMergeReturnOptions,TclProcessReturn):
	* generic/tclCompCmds.c (TclCompileReturnCmd):
	* generic/tclExecute.c (TclCompEvalObj):
	* generic/tclInt.h (Interp):
	* generic/tclProc.c (TclUpdateReturnInfo):
	Place primary storage of the -level and -code information in private
	fields of the Interp struct, rather than in a DictObj.  This should
	significantly improve performance of TclUpdateReturnInfo.

2004-10-17  Miguel Sofer <msofer@users.sf.net>

	* generic/tclResult.c: removed unused variable [Bug 1048588]. 
	Thanks to Daniel South.

2004-10-15  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c (TclProcessReturn):	Now that primary
	* generic/tclProc.c (TclUpdateReturnInfo):	storage for the
	errorInfo and errorCode values are internal fields, we can set
	them at the time of the [return] command, and not have to wait
	until the specified number of "-level"s have popped.

	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp,
		TclEvalObjvInternal,Tcl_LogCommandInfo,TclAddObjErrorInfo):
	* generic/tclCmdAH.c (Tcl_CatchObjCmd):
	* generic/tclEvent.c (BgError,ErrAssocData,Tcl_BackgroundError,
		HandleBgErrors,BgErrorDeleteProc):
	* generic/tclExecute.c (TclCreateExecEnv,TclDeleteExecEnv):
	* generic/tclIOUtil.c (comments only):
	* generic/tclInt.h (ExecEnv,Interp, ERR_IN_PROGRESS):
	* generic/tclInterp.c ([tclInit]):
	* generic/tclMain.c (comments only):
	* generic/tclNamesp.c
		(Tcl_CreateNamespace,Tcl_DeleteNamespace,TclTeardownNamespace):
	* generic/tclProc.c (TclUpdateReturnInfo):
	* generic/tclResult.c
		(Tcl_ResetResult,TclTransferResult):
	* generic/tclTrace.c (CallVarTraces):
	Reworked management of the "errorInfo" data of an interp.
	That information is now primarily stored in a new private
	(Tcl_Obj *) field of the Interp struct, rather than using a
	global variable ::errorInfo as the primary storage.  The
	ERR_IN_PROGRESS flag bit value is no longer required to manage
	the value in its new location, and is removed.  Variable traces
	are established to support compatibility for any code expecting
	the ::errorInfo variable to hold the information.

	***POTENTIAL INCOMPATIBILITY***
	Code that sets traces on the ::errorInfo variable may notice a
	difference in timing of the firing of those traces.  Code that
	uses the value ERR_IN_PROGRESS.

2004-10-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	TIP#217 IMPLEMENTATION

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Add -indices option from
	James Salsman. [Patch 1017532]

	* generic/tclUtil.c (TclMatchIsTrivial): Detect degenerate cases
	of glob matching that let us avoid scanning through hash tables.
	* generic/tclCmdIL.c (InfoCommandsCmd, InfoGlobalsCmd, InfoProcsCmd):
	(InfoVarsCmd): Use this to speed up some [info] subcommands.

2004-10-12  Kevin B. Kenny  <kennykb@acm.org>

	* library/tzdata/America/Campo_Grande:
	* library/tzdata/America/Cuiaba:
	* library/tzdata/America/Sao_Paulo
	* library/tzdata/America/Argentina/Mendoza:
	* library/tzdata/America/Argentina/San_Juan:
	Synchronized to Olson's 'tzdata2004e'.

2004-10-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	TIP#201 AND TIP#212 IMPLEMENTATIONS

	* doc/dict.n, doc/expr.n: Documentation for new functionality.
	* tests/expr.test: Basic tests of 'in' and 'ni' behaviour.
	* tests/dict.test (dict-21.*,dict-22.*): Tests for [dict update]
	and [dict with].
	* generic/tclExecute.c (TclExecuteByteCode): Implementation of the
	INST_LIST_IN and INST_LIST_NOT_IN bytecodes.
	* generic/tclParseExpr.c (GetLexeme): Parse the 'in' and 'ni'
	operators for TIP#201.
	* generic/tclDictObj.c (DictUpdateCmd,DictWithCmd): Core of
	implementation of TIP#212; docs and tests still to do...

2004-10-07  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclTest.c (TestsetobjerrorcodeCmd):  Simplified.

2004-10-07  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c:
	* generic/tclFileSystem.h:
	* generic/tclIOUtil.c:
	* generic/tclPathObj.c:
	* unix/tclUnixFile.c:
	* win/tclWinFile.c:
	* tests/fileName.test:
	* tests/winFCmd.test: code reorganization for better generic/
	platform code splitting [Bug 925620] removing the need for
	several #ifdef's, and tests and fix for an unreported Windows 
	glob problem ('glob -dir C: -tails *').

2004-10-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* *.3: Convert CONST to const and VOID to void so we document how
	people should actually use the Tcl API and not the compatability
	hacks that it has to have.

	* doc/man.macros, *.3: Update .AS macro so it can know how wide to
	make the third column of the argument list. Update documentation
	for C API (only users) to take advantage of this.

	* doc/FileSystem.3: Formatting fixes for greater documentation
	clarity.

2004-10-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclFileName.c (DoGlob, TclGlob): Stop messy sharing of
	interpreter result and instead use a private object for collecting
	the result of the glob. This simplifies TclGlob quite a lot.
	* generic/tclIOUtil.c (Tcl_FSMatchInDirectory): Simplify by
	removing some nesting. Also standardize variable names.
	(FsAddMountsToGlobResult): Force updates to the list to be done
	in-place, putting a side-condition of non-shared-ness on the
	resultPtr argument to Tcl_FSMatchInDirectory, but everything would
	have broken before if that was shared *anyway*.

	* generic/tclEncoding.c (LoadTableEncoding): Removed reference to
	Tcl interpreter; it wasn't needed as direct object use is more
	efficient.

	* generic/tclPathObj.c: Made this file follow the style rules in
	the Engineering Manual more closely, and also take advantage of
	the internal object manipulation macros more.

	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Reorganized to have fewer
	magic flag variables and to separate the code that scans for a
	match from the code that processes a match body.

	It is a poor practice to directly set or append to the value
	of the objResult of an interp, because that value might be
	shared, and in that circumstance a Tcl_Panic() will be the
	result.  Searched for example of this practice and replaced
	with safer alternatives, often using the Tcl_AppendResult()
	routine that dkf just rehabilitated.
	* library/dde/pkgIndex.tcl: Bump to dde 1.3.1
	* library/reg/pkgIndex.tcl: Bump to registry 1.1.5

2004-10-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/SetResult.3: Made Tcl_AppendResult non-deprecated; better
	that people use it than most of the common alternatives!
	* generic/tclResult.c (Tcl_AppendResultVA): Make this work better
	with Tcl_Objs. [Patch 1041072]
	(Tcl_SetResult, Tcl_AppendElement): Change string to stringPtr to
	avoid C++ keywords.

2004-10-05  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (TclObjInvoke): More simplification of the
	TclObjInvoke routine toward unification with the rest of the
	evaluation stack.

	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp,
		TclEvalObjvInternal,Tcl_LogCommandInfo):
	* generic/tclCmdAH.c (Tcl_CatchObjCmd):
	* generic/tclEvent.c (BgError,Tcl_BackgroundError,HandleBgErrors):

		(Tcl_CreateNamespace,Tcl_DeleteNamespace,TclTeardownNamespace):
	* generic/tclResult.c

	* generic/tclTrace.c (CallVarTraces):
	Reworked management of the "errorCode" data of an interp.
	That information is now primarily stored in a new private
	(Tcl_Obj *) field of the Interp struct, rather than using a
	global variable ::errorCode as the primary storage.  The
	ERROR_CODE_SET flag bit value is no longer required to manage
	the value in its new location, and is removed.  Variable traces
	are established to support compatibility for any code expecting

	***POTENTIAL INCOMPATIBILITY***
	Code that sets traces on the ::errorCode variable may notice a
	difference in timing of the firing of those traces.

	* generic/tclNamesp.c (Tcl_PopCallFrame):	Removed Bug 1038021
	workaround.  That bug is now fixed.

2004-10-04  Kevin B. Kenny  <kennykb@acm.org>

	* tests/clock.test (clock-34.*): Removed an antibug that forced
	comparison of [clock scan] results with the :localtime time zone.
	Now that [clock scan] uses the current time zone instead, the
	antibug caused several tests to fail. [Bug 1038554]

2004-10-04  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclParseExpr.c (GetLexeme): Ensure that the 'eq' and
	'ne' operators are followed by non-alphabetic characters so
	lexemes can't run together. [Bug 884830]

	* doc/DictObj.3, doc/dict.n: Clarified that a dictionary is not
	order-preserving. [Bug 1032243]  Also added another example to
	show off more ways of using a dictionary and a few other
	formatting improvements.

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

	* generic/tclDictObj.c (TraceDictPath, Tcl_DictObjPutKeyList): Add
	support for automatic creation of dictionary paths since that is
	what everyone seems to actually expect of the API! [Bug 1037235]
	(Tcl_DictObjNext): Make calling this after Tcl_DictObjDone non-fatal
	as that simplifies a number of internal APIs. This doesn't break any
	existing working code as it is a case which previously caused a panic.

	* tests/namespace.test (namespace-8.7):	Another test for save/restore
	of ::errorInfo and ::errorCode during global namespace teardown.

	* generic/tclProc.c (TclObjGetFrame, Tcl_UplevelObjCmd):

	references in the level object for speed.

2004-09-30  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_CreateInterp): Removed the flag bit value
	* generic/tclInt.h (Interp):	EXPR_INITIALIZED.  It was set during
	interp creation and never tested.  Whatever purpose it had is in
	the past.

	* generic/tclBasic.c (Tcl_EvalObjEx):	Removed the flag bit value
	* generic/tclInt.h (Interp):	USE_EVAL_DIRECT.  It was used only
	* generic/tcLTest.c (TestevalexObjCmd):	in the testing command
	* tests/parser.test (parse-9.2): [testevalex] and nothing in the
	test suite made use of the capability it enabled.

	* generic/tclBasic.c (Tcl_AddObjErrorInfo): More re-organization
	* generic/tclCmdAH.c (Tcl_ErrorObjCmd):     of the management of
	* generic/tclCmdMZ.c (TclProcessReturn):    the errorCode value.
	* tests/error.test (error-6.4-9):

	* generic/tclNamespace.c (TclTeardownNamespace): Tcl_Obj-ified
	* tests/namespace.test (namespace-8.5,6):	the save/restore
	of ::errorInfo and ::errorCode during global namespace teardown.
	Revised the comment to clarify why this is done, and added tests
	that will fail if this is not done.

	* generic/tclResult.c (TclTransferResult):	Added safety
	checks so that unexpected undefined ::errorInfo or ::errorCode
	will not lead to a segfault.

	* generic/tclTrace.c (TclCallVarTraces):     Save/restore the flag
	* tests/var.test (var-16.1):	values that define part of the
	interpreter state during variable traces.  [Bug 1038021].

2004-09-30  Miguel Sofer <msofer@users.sf.net>

	* tests/subst.test (12.1-2): added tests for [Bug 1036649]

	* generic/tclBasic.c (TclObjInvoke): fix for bogus gcc warning
	about uninitialised variable.

2004-09-27  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Removed internal routines TclInvoke,
	* generic/tclInt.decls: TclGlobalInvoke, TclObjInvokeGlobal and
	* tests/basic.test:	the portion of TclObjInvoke that handles
	calls without TCL_INVOKE_HIDDEN enabled.  None of this code is
	called any longer within the core, and the superior public
	interface, Tcl_EvalObjv, is available for any external callers.

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

	* generic/tclEvent.c (HandleBgErrors):	Updated [bgerror]
	invocations to make use of Tcl_Obj based routines, dropping
	the calls to TclGlobalInvoke()

2004-09-27  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c:

	* generic/tclIOUtil.c:
	* generic/tclPathObj.c:
	* tests/cmdAH.test:
	* tests/fileSystem.test:

	windows, when permissions are inadequate [Bug 1035462] and
	to treatment of a volume-relative pwd on Windows [Bug 1018980].

	* doc/FileSystem.3: added missing Tcl_GlobTypeData documentation
	[Bug 935853]

2004-09-27  Kevin Kenny  <kennykb@acm.org>

	* compat/strftime.c (Removed):
	* generic/tclClock.c (removed TclClockOldscanObjCmd):
	* generic/tclDate.c (Regenerated):
	* generic/tclGetDate.y:
	* generic/tclInt.decls (removed TclGetDate and TclpStrftime):
	* generic/tclInt.h (removed TclGetDateInfo):
	* generic/tclIntDecls.h (Regenerated):
	* generic/tclStubInit.c (Regenerated):

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

	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Removed some grubby
	* generic/tclObj.c (SetBooleanFromAny):  work-around code
						 that was needed only
						 because of Bug 868489.

	* generic/tclBasic.c (TclObjInvoke): Removed three unused
	variables to silence a compiler warning in VC++.

2004-09-27  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/FileSystem.3: fix to small typo.

2004-09-23  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/dltest/Makefile.in (clean): Fixup make clean
	rule so that it does not delete all files when
	SHLIB_SUFFIX is set to the empty string in a static build.
	[Bug 1016726]

2004-09-23  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Corrections to the 2004-09-21 commit
	* generic/tclExecute.c:	regarding ERR_ALREADY_LOGGED.  That commit
	* generic/tclNamesp.c:	caused Tk test send-10.7 to fail.  Added
	* tests/namespace.test (25.7,8):	tests in the Tcl test suite
	* tests/pkg.test (2.25,26):	to catch this error without the
	aid of Tk in the future.

	* generic/tclCmdAH.c (Tcl_ExprObjCmd):	Simplified the TclObjCmdProc
	of [expr] with a call to Tcl_ConcatObj.

2004-09-22  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c (TclProcessReturn):	Support the -errorline
	* generic/tclCompile.c (TclCompileScript):	option to [return].
	* tests/compile.test (16.23.*):	Use that capability to defer reporting
	* tests/misc.test (1.2):	of parse errors until runtime.
	Updated tests to reflect change. [Bug 1032805]

2004-09-22  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (INST_START_CMD):
	* tests/proc.test (7.2-3): fix for [Bug 729692] was incorrect
	whenever a loop exception was returned.

2004-09-22  Kevin B. Kenny  <kennykb@acm.org>

	* library/tzdata/America/Montevideo: Updated to reflect
	ftp://elsie.nci.nih.gov/pub/tzdata2004d.tar.gz. (Changes
	to Asia/Jerusalem were in the comments only.) [Routine
	maintenance - no bug] Spanish-language description of the
	change at http://www.presidencia.gub.uy/decretos/2004091502.htm

2004-09-21  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompCmds.c:	Tolerate [append] syntax errors
	* tests/appendComp.test (8.1):	at compile time, and allow runtime
	to raise the error (or succeed if a redefined [append] allows).

	* generic/tclBasic.c:	Reworked management of the interp
	* generic/tclCompile.c:	flag ERR_ALREADY_LOGGED, to reduce
	* generic/tclExecute.c: its exposure.  Still left several
	* generic/tclNamesp.c:	references that are just too nice
	on performace to do away with.  These changes also resolve
	an inconsistency in the ::errorInfo values produced by
	[namespace eval x error foo bar] and
	[namespace eval x {error foo bar}].

	* generic/tclExecute.c (TclCompEvalObj):	Simplified
	the TclCompEvalObj routine.  Much housekeeping now reliably
	happens elsewhere.  [Patch 1031949]

2004-09-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/interp.n: Tighten up wording on how [interp eval] and
	[interp invokehidden] operate w.r.t. stack frames. [Bug 926590]

2004-09-20  Don Porter  <dgp@users.sourceforge.net>

	* tests/error.test (error-6.2,3):	Added more tests to verify
	::errorCode setting by/after a [catch].

2004-09-19  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCmdAH.c: removed outdated comment [Bug 1029518].

2004-09-18  David Gravereaux <davygrvy@pobox.com>

	* win/tclAppInit.c: Dde package can load into a safe interp.
	Claim this fact for the Tcl_StaticPackage() call when the shell
	is built with the TCL_USE_STATIC_PACKAGES option.

2004-09-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclExecute.c (TEBC-INST_LSHIFT,INST_RSHIFT): Ensure that
	large shifts end up shifting correctly. [Bug 868467]

	* doc/FileSystem.3, doc/OpenFileChnl.3: More documentation fixes
	from Mikhail Kolesnitchenko. [Patch 1022527]
	* doc/*: Standardize highlighting of symbols defined in tcl.h

2004-09-17  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_AddObjErrorInfo, Tcl_LogCommandInfo):
	* generic/tclCmdAH.c ([catch], [error]):
	* generic/tclCmdMZ.c ([return]):
	* generic/tclProc.c (TclUpdateReturnInfo):
	* generic/tclResult.c (Tcl_SetErrorCodeVA, Tcl_SetObjErrorCode)
	(TclTransferResult): 	Refactored so that all errorCode setting
	flows through Tcl_SetObjErrorCode().  This greatly reduces the
	number of different places in the code that need to know details
	about an internal bitflag field of the Interp struct.  Also
	places errorCode setting in one place for easier future mods.

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

	* generic/tclDate.c:    Revised tclGetDate.y to use bison instead
	* generic/tclGetDate.y: of yacc to build the parser, eliminating
	* generic/tclInt.h:     all the complicated hackery involving
	* unix/Makefile.in:     'sed' postprocessing.  Rebuilt the parser.

2004-09-14  Kevin B. Kenny  <kennykb@acm.org>

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

2004-09-10  Miguel Sofer <msofer@users.sf.net>

	* doc/interp.n:
	* generic/tclInterp.c (TclPreventAliasLoop, AliasCreate):
	* tests/interp.test (17.4-6, 19.3-4): fixing problems with
	renaming of aliases [Bugs 707104 1026493]. Fix designed by dgp. 

2004-09-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclNamesp.c (NsEnsembleImplementationCmd): Add token
	field to internal rep of EnsembleCmdRep structure so that we can
	check it to see if the subcommand object is really being used with
	the same ensemble. [Bug 1026903]

2004-09-11  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclClock.c (TclMktimeObjCmd): Corrected a bad check
	for error return from 'mktime'.
	* generic/tclObj.c (Tcl_GetIntFromObj): Corrected a problem where
	demoting a wide to an int failed on a big-endian machine.
	[Bug 1026125].
	* tests/clock.test (clock-43.1): Added regression test for
	error return from 'mktime'.

2004-09-11  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (INST_CONCAT1): fix for [Bug 1025834];
	avoid unnecessary string copies.

2004-09-10  David Gravereaux <davyrgvy@pobox.com>

	* tests/tcltest.test: tcltest-12.3-4 needed to have
	::tcltest::loadScript set to empty in their -setup

2004-09-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclObj.c (SetIntOrWideFromAny): Rewritten integral value
	parsing code so that values do not flip so easily between numeric
	representations. Thanks to KBK for this! [Bug 868489]

	* generic/tclIO.c (Tcl_Seek): Make sure wide seeks do not fail to
	set ::errorCode on error. [Bug 1025359]

2004-09-10  Andreas Kupries  <andreask@activestate.com>

	* generic/tcl.h: Micro formatting fixes.
	* generic/tclIOGT.c: Channel version fixed, must be 3, to have
	  wideseekProc. Thanks to David Graveraux <davygrvy@pobox.com>.

2004-09-11  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclNamespace.c (TclGetNamespaceForQualName):	Resolved
	longstanding inconsistency in the treatment of the TCL_NAMESPACE_ONLY
	flag revealed by testing the 2004-09-09 commits against Itcl.
	TCL_NAMESPACE_ONLY now acts as specified in the pre-function
	comment, forcing resolution in the passed in context namespace.
	It has been incorrectly forcing resolution in the interp's current
	namespace.

2004-09-10  Kevin Kenny  <kennykb@acm.org>

	* library/clock.tcl: Fixed a bug where %z always put a plus
	sign on the time zone in :localtime.
	* tests/clock.test: Added test case for the above bug.

2004-09-10  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (INST_CONCAT1): added a peephole
	optimisation for concatting an empty string. This enables
	replacing the idiom 'K $x [set x {}]' by '$x[set x {}]' for
	fastest execution.

2004-09-09  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinConsole.c: Calls to WriteFile and WriteConsoleA
	changed to WriteConsole for simplicity.

2004-09-09  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclNamesp.c (Tcl_ForgetImport):	Corrected faulty
	* tests/namespace.test:	logic that relied exclusively on string
	matching and failed in the presence of [rename]s.  [Bug 560297]
	Also corrected faulty prevention of [namespace import] cycles.
	[Bug 1017299]

2004-09-08  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_CreateInterp):	Removed obsolete
	field for storing the string-based command procedure of built-in
	commands.  We no longer have any string-based built-in commands!

2004-09-08  Kevin B. Kenny <kennykb@acm.org>

	* compat/strftime.c (_conv): Corrected a problem where hour 0
	would format as a blank format group with %k.
	* doc/clock.n: Corrected a buglet in the header information.
	[Bug 1024058]
	* generic/tclClock.c (TclClockMktimeObjCmd): Fixed a bug where
	the month was scanned incorrectly in -timezone :localtime.
	* tests/clock.test (clock-34.*,clock-40.1, clock-41.1): Adjusted the
	clock-34.* test cases so that the consistency check is performed
	in :localtime rather than the current time zone.  This change
	allows dealing with issues where the C library has a different
	idea of DST conversion than Tcl. (Real fix would be to break
	TclGetDate into separate parser and time converter, and do
	the time conversion in clock.tcl. That's for another day.)
	Added regression test case for the bug where month was scanned
	incorrectly in -timezone :localtime. [Bug 1023779] Added 
	regression test case for %k at the zero hour.

2004-09-07  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc: some quoting needed to be removed as it was
	breaking with VC7. [Bug 1023150]

2004-09-07  Kevin B. Kenny  <kennykb@acm.org>

	* doc/clock.n: Documented the default -format, and changed
	references to a (nonexistent) msgcat command to refer to
	the msgcat package. [Bug 1023870]
	* generic/tclTimer.c: Removed a premature optimisation that
	attempted to store the assoc data in the client data; the
	optimisation caused a bug that [after] would overwrite
	its imports.  [Bug 1016167]
	* library/clock.tcl (InitTZData, ClearCaches): Changed so that the
	in-memory time zone :UTC (and its aliases) always gets
	reinitialised, in case tzdata is absent. [Bug 1019537, 1023779]
	* library/tzdata/*: Regenerated.
	* tests/clock.test (clock-31.*, clock-39.1): Corrected a problem
	where the 'system' locale tests fail on a non-English Windows
	machine. [Bug 1023761].  Added a test to make sure that alias
	time zones load correctly. [Bug 1023779].
	* tests/timer.test (timer-1.1, timer-2.1): Changed to (one hopes!)
	be more resilient on an overloaded system, if [after 200] sleeps
	for 300 ms or longer.
	* tools/tclZIC.tcl (writeLinks): Corrected a problem where
	alias time zone names were written incorrectly, causing them
	to fail to load at run time. [Bug 1023779].
	* win/tclWinTime.c (Tcl_GetTime): Eliminated CPUID tests on
	Win64 - assuming that HAL vendors now do a better job of
	keeping the performance counters synchronized among CPU's.
	[Bug 1020445]

	* generic/tclNamesp.c (FindEnsemble): Factor out the code to
	convert a command name into an ensemble configuration and add
	support for ignoring [namespace import] link chains. [Bug 1017022]
	(NamespaceWhichCmd): Rework to use newer option parsing API.

2004-08-27  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in: added customization of default module path roots
	via TCL_MODULE_PATH makefile variable.
	* macosx/Makefile: add platform standard locations to default
	module path roots. [Patch 942881]

	* tests/env.test: macosx fixes.

2004-08-25  Don Porter  <dgp@users.sourceforge.net>

	* tests/timer.test (timer-10.1):	Test for Bug 1016167.
	* generic/tclTimer.c:	Workaround for situation when a
	[namespace import] causes the objv[0] value to be something
	other than what Tcl_AfterObjCmd expects.  [Bug 1016167].

2004-08-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclNamesp.c (NsEnsembleImplementationCmd): Use the
	ensemble command token to get the name of the ensemble for passing
	to the -unknown handler instead of relying on objv[0], which may
	contain useless info in the presence of [namespace import].
	Problem found by Don Porter when investigating [Bug 1016167].

2004-08-24  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclProc.c:		The routine TclProcInterpProc was a
	* generic/tclTestProcBodyObj.c:	specific instance of the general
	service already provided by TclObjInvokeProc.  Removed
	TclProcInterpProc and TclGetInterpProc from the code...

	* generic/tclInt.decls	...and from the internal stubs table.
	* generic/tclIntDecls.h
	* generic/tclStubInit.c

2004-08-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/string.n: Added clarifying note.

2004-08-23  Don Porter  <dgp@users.sourceforge.net>

	* library/auto.tcl:	Updated [tcl_findLibrary] search path
	to include any [<pkg>::pkgconfig get scriptdir,runtime] directory,
	as well as the $::auto_path.  [RFE 695441]

2004-08-21  Kevin B. Kenny  <kennykb@acm.org>

	* tests/clock.test (clock-38.1): Changed TZ setting to specify
	CET in excruciating detail to deal with systems that lack the
	Posix defaults for DST changes (and to be formally correct with
	the change dates for CET).

2004-08-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclScan.c (Tcl_ScanObjCmd, ValidateFormat): Ensure that
	the %ld conversion works correctly on 64-bit platforms. [Bug 1011860]

2004-08-19  Kevin Kenny  <kennykb@acm.org>

	* library/clock.tcl (format): Changed default timezone format
	from alphabetic to numeric to produce scannable times in more
	locales.
	* tests/clock.test (clock-37.1): Removed now-unused 'needPST'
	constraint and the comments that refer to it.

2004-08-18  Andreas Kupries  <andreask@activestate.com>

	* library/init.tcl: Integrated TIP #189. We source a separate file
	  (see below), instead of inlining the contents of that file. This
	  should beeasier to maintain, and easier to backport/install in
	  8.4 installations.

	  Note: Usage of Tcl Modules is restricted to non-safe interps. It
	  cannot be loaded into a safe interp.

	* library/tm.tcl: New file, the v2 reference implementation for
	  TIP #189, Tcl Modules.

	* doc/tm.n: New file, documentation for Tcl Modules, based on the
	  TIP.

	* unix/mkLinks: Regenerated.
	* win/makefile.vc: Added tm.tcl to list of files to install.

2004-08-18  Kevin Kenny  <kennykb@acm.org>

	* tests/httpd (httpdRespond): Corrected an abuse of the [clock]
	command that caused test failures for some values of [clock clicks].

		Implementation of TIPs #173 and #209.

	The [clock] command is now a Tcl ensemble, with most of its
	functionality written in Tcl and callouts to C code only to
	access low-level functions such as localtime, mktime and
	tzset.

	In addition to the functionality changes called out in the two
	TIPs, it is worth noting that the [clock] command in a safe
	slave interpreter is now an alias to the [clock] command in the
	master, and that [clock] is otherwise not expected to function
	entirely correctly in safe interps.  C code that simply does
	Tcl_MakeSafe needs to be aware that [clock] may need special
	handling.  (It appears unlikely that such code actually exists.)

	One incompatibility of note is that if the time zone cannot
	be determined from the TZ, TCL_TZ environment variables, or
	from the Windows control panel, so that the C library must be
	used for date and time conversions, then times outside the
	range of time_t will fail; they used to return bad data silently.

	Many thanks to all the many people who assisted with testing,
	debugging, criticism of the specification, and localisation.
	Deserving of particular mention are Joe English, Clif Flynt, Donal
	K. Fellows, Jeff Hobbs, Cameron Laird, Arjen Markus, Reinhard Max,
	Christopher Nelson, Steve Offutt, Donald G. Porter, Pascal
	Scheffers, Peter da Silva and Richard Suchenwirth-Bauersachs.

2004-08-10  Zoran Vasiljevic <vasiljevic@users.sf.net>

	* unix/tclUnixThrd.c (TclpThreadCreate): changed handling of

	labels to make the code clearer.

2004-08-02  Don Porter  <dgp@users.sourceforge.net>

	* library/package.tcl (pkg_mkIndex):	Updated [pkg_mkIndex] to
	make use of [glob -directory $dir -tails] and return options.

	TIP#207 IMPLEMENTATION

	* doc/interp.n:		Added support for a -namespace option to the
	* generic/tclBasic.c:	[interp invokehidden] command.  Also added an
	* generic/tclInt.h:	internal routine TclObjInvokeNamespace() and
	* generic/tclInterp.c:	corrected the flag names TCL_FIND_ONLY_NS and
	* generic/tclNamesp.c:	TCL_CREATE_NS_IF_UNKNOWN that are passed to the
	* generic/tclTrace.c:	internal routine TclGetNamespaceForQualName().
	* tests/interp.test:	[Patch 981841]

	* generic/tclLiteral.c (TclCleanupLiteralTable):	Corrected
	* tests/compile.test (compile-12.4):	flawed deletion of literal

	Thanks to Kevin Kenny for test case and fix [Bug 1001997].

2004-07-30  Don Porter  <dgp@users.sourceforge.net>

	* tests/safe.test (safe-2.1):  Disabled senseless test.  [Bug 999612]

	* library/auto.tcl (auto_reset):  Removed "protected" list of commands 
	from [auto_reset].  All entries in the auto_index can be re-loaded.
	* library/package.tcl: Updated comment to reflect 2004-07-28 commit.

	* generic/tclEvent.c (Tcl_Finalize):	Re-organized Tcl_Finalize
	so that Tcl_ExitProc's that call Tcl_Finalize recursively do not
	cause deadlock.  [Patch 999084 fixes Tk Bug 714956]

2004-07-30  Daniel Steffen  <das@users.sourceforge.net>

	* unix/configure:
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Darwin: instead of setting PLAT_OBJS 
	to explict object files in tcl.m4, refer to MAC_OSX_OBJS makefile var.
	* unix/Makefile.in: added MAC_OSX_OBJS variable.

2004-07-29  Don Porter  <dgp@users.sourceforge.net>

	* library/package.tcl:	[::pkg::create] is now an alias.  Test
	safe-2.1 will now fail until Bug 999612 is corrected.

2004-07-28  Don Porter  <dgp@users.sourceforge.net>

	* library/package.tcl:		Moved private command
	* library/tclIndex:		[pkg_compareExtension] into ::tcl::Pkg.
	* tests/pkg_mkIndex.test:	Also moved implementation of
	[::pkg::create] to [::tcl::Pkg::Create].

2004-07-25  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* tests/io.test: Make io-61.1 create file as binary to pass on Win32

2004-07-23  Miguel Sofer <msofer@users.sf.net>

	* generic/tclVar.c: simplify tclLocalVarNameType, removing the
	reference to the corresponding proc. The reference is now seen as
	unnecessary, and it may cause leaking circular references under
	some circumstances (see for example [Bug 994838]).

2004-07-22  Don Porter  <dgp@users.sourceforge.net>

	* tests/eofchar.data (removed): Test io-61.1 now generates its own
	* tests/io.test:        file of test data as needed.

2004-07-20  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclEvent.c:       Correct threaded obj allocator to
	* generic/tclInt.h:         fully cleanup on exit and allow for
	* generic/tclThreadAlloc.c: reinitialization. [Bug #736426]
	* unix/tclUnixThrd.c:       (mistachkin, kenny)
	* win/tclWinThrd.c:

2004-07-21  Kevin Kenny  <kennykb@acm.org>

	* generic/tclBasic.c (DeleteInterpProc):
	* generic/tclLiteral.c (TclCleanupLiteralTable):
	* generic/tclInt.h: added a TclCleanupLiteralTable function,
	called from DeleteInterpProc, that frees internal representations
	of shared literals early when an interpreter is being deleted.
	This change corrects a number of memory mismanagement issues in
	the cases where the internal representation of one literal
	contains a reference to another, and avoids conditions such as
	resolved variable names referring to procedure and namespace
	contexts that no longer exist.  [Bug 994838]

2004-07-20  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in:
	* win/Makefile.in: added 'install-private-headers' makefile target
	to allow optionally installing private tcl headers. [FR 922727]

	* macosx/Makefile: use new 'install-private-headers' target
	to install private headers into framework. [FR 922727]

	* unix/tclUnixFile.c (NativeMatchType): added support for
	readonly matching of user immutable files (where available).

	* macosx/tclMacOSXBundle.c: dynamically acquire address for
	CFBundleOpenBundleResourceMap symbol, since it is only present in
	full CoreFoundation on Mac OS X and not in CFLite on pure Darwin.

2004-07-19  Zoran Vasiljevic <vasiljevic@users.sf.net>

	* win/tclwinThrd.c: redefined MASTER_LOCK to call 
	TclpMasterLock. Fixes Bug #987967

2004-07-17  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: fix to rare 'cd' infinite loop in
	normalization with vfs [Bug 991420].
	* tests/fileSystem.test: added test for above bug.

	* doc/FileSystem.3: clarified documentation of posix error
	codes in 'remove directory' FS proc - 'EEXIST' is used to
	signify a non-empty directory error (bug reported against
	tclvfs).

2004-07-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/Makefile.in, unix/tcl.m4:     move (C|LD)FLAGS after their
	* unix/configure.in, unix/configure: _DEFAULT to allow for env
	setting to override m4 switches.  Move SC_MISSING_POSIX_HEADERS up
	and consolidate calls to limit redundancy in configure.
	(CFLAGS_WARNING): Remove -Wconversion
	(SC_ENABLE_THREADS): Set m4 to force threaded build when built
	against a threaded Tcl core.

2004-07-16  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Corrected a typo in the
	  generation of error messages and simplified by reusing data in a
	  variable instead of retrieving the string again.
	  Fixes [Tcl SF Bug 835289].

	* doc/OpenFileChnl.3: Added description of the behaviour of
	  Tcl_ReadChars when its 'charsToRead' argument is set to
	  -1. Fixes [Tcl SF Bug 934511].

	* doc/CrtCommand.3: Added note that the arguments given to the
	  command proc of a Tcl_CreateCommand are in utf8 since Tcl
	  8.1. Closing [Tcl SF Patch 414778].

	* doc/ChnlStack.3: Removed the declaration that the interp
	  argument to Tcl_(un)StackChannel can be NULL. This fixes [Tcl SF
	  Bug 881220], reported by Marco Maggi
	  <marcomaggi@users.sourceforge.net>.

	* tests/socket.test: Accepted two new testcases by Stuart Casoff
	  <stwo@users.sourceforge.net> checking that -server and -async
	  don't go together [Tcl SF Bug 796534].

	* unix/tclUnixNotfy.c (NotifierThreadProc): Accepted Joe
	  Mistachkin's patch for [Tcl SF Bug 990500], properly closing the
	  notifier thread when its exits.

2004-07-15  Andreas Kupries  <andreask@activestate.com>

	* unix/tclUnixThrd.c (TclpFinalizeMutex): Accepted Joe
	  Mistachkin's patch for [Tcl SF Bug 990453], closing leakage of
	  mutexes. They were not destroyed properly upon finalization.

2004-07-15  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.h (CHANNEL_INCLOSE):       New flag. Set in
	* generic/tclIO.c (Tcl_UnregisterChannel): 'Tcl_Close' while the
	* generic/tclIO.c (Tcl_Close):             close callbacks are
	  run. Checked in 'Tcl_Close' and 'Tcl_Unregister' to prevent
	  recursive call of 'close' in the close-callbacks. This is a
	  possible error made by implementors of virtual filesystems based
	  on 'tclvfs', thinking that they have to close the channel in the
	  close handler for the filesystem.

2004-07-14  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c:
	* generic/tclIO.h:
	* Not reverting, but #ifdef'ing the changes from May 19, 2004 out
	  of the core. This removes the ***POTENTIAL INCOMPATIBILITY***
	  for channel drivers it introduced. This has become possible due
	  to Expect gaining a BlockModeProc and now handling blockingg and
	  non-blocking modes correctly. Thus [SF Tcl Bug 943274] is still
	  fixed if a recent enough version of Expect is used.

	* doc/CrtChannel.3: Added warning about usage of a channel without
	  a BlockModeProc.

2004-07-15  Andreas Kupries  <andreask@pliers.activestate.com>

	* generic/tclIOCmd.c (Tcl_PutsObjCmd): Added length check to the
	  old depreceated newline syntax, to ensure that only "nonewline"
	  is accepted. [Tcl SF Bug 985869], reported by Joe Mistachkin
	  <mistachkin@users.sourceforge.net>.

2004-07-15  Zoran Vasiljevic <vasiljevic@users.sf.net>

	* generic/tclEvent.c (Tcl_Finalize): stuffed memory leak
	incurred by re-initializing of TSD slots after the last call to
	TclFinalizeThreadData (done from within Tcl_FinalizeThread()).
	We basically just repeat the TclFinalizeThreadData() once more 
	before tearing down TSD keys in TclFinalizeSynchronization().  
	There should be more elaborate mechanism in place for handling
	such issues, based on thread cleanup handlers registered on the
	OS level. Such change requires much more work and would also
	require TIP because some visible parts of Tcl API would have to
	be modified. In the meantime, this will do.

	* generic/tclNotify.c (TclFinalizeNotifier): Added conditional
	notifier finalization based on the fact that an TclInitNotifier
	has been called for the current thread. This fixes the Tcl
	Bug #770053 again. Hopefully this time w/o unwanted side-effects.

2004-07-15  Kevin Kenny  <kennykb@acm.org>

	* generic/tclLiteral.c (TclReleaseLiteral): Removed unused
	variable 'codePtr' to silence a message from VC++.

2004-07-15  Miguel Sofer <msofer@users.sf.net>

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

2004-07-15  Zoran Vasiljevic <vasiljevic@users.sf.net>

	* generic/tclEvent.c (NewThreadProc): Backout of changes
	to fix the Tcl Bug #770053. See SF bugreport for more info.

2004-07-11  Miguel Sofer <msofer@users.sf.net>

	* generic/tclBasic.c (Tcl_EvalEx): leak fix by dgp, release
	objv[objectsUsed] on error.

2004-07-11  Miguel Sofer <msofer@users.sf.net>

	* generic/tclParse.c (Tcl_SubstObj): leak fix by dgp, release
	result on error.

2004-07-11  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclNamesp.c (BuildEnsembleConfig): Don't forget to clean
	out references when deleting the hash table.
	* generic/tclDictObj.c (Tcl_DictObjRemoveKeyList): Oops, forgot to
	delete value object when removing the hash entry. [Bug 989093 in part]

2004-07-11  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (TEBC): fixed leak of expandNestList objs 
	when there is an error while an expansion is in progress (code
	added at checkForCatch).

2004-07-11  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: fix to 'cd' bug when vfs is active
	[Bug 986944 in tclvfs project] - this bug recently introduced
	by some threading fixes.  Need to work out how to add
	tests for this.

2004-07-10  Kevin Kenny  <kennykb@acm.org>

	* tests/clock.test (clock-2.11): Changed the test so that
	it isn't an infinite loop when run under valgrind on a slow
	virtual machine.  Thanks to Miguel Sofer for the bug report.
	Also put in code to restore env(LC_TIME) after tests complete,
	silencing a warning from 'make TESTFLAGS="-debug 1" test'.

2004-07-08  Miguel Sofer <msofer@users.sf.net>

	* generic/tclBasic.c (DeleteInterpProc): reverted the modification
	of 3 days ago, as the leak of [Bug 983660] is now handled by the
	change in TclCleanupByteCode.
	* generic/tclCompile.c (TclCleanupByteCode): let each bytecode
	remove its references to literals at interp deletion, without
	updating the dying literal table.
	* generic/tclLiteral.c (TclDeleteLiteralTable): with the above
	change to TclCleanupByteCode, this function now removes a single
	reference to the literal object and cleans up its own structures.

2004-07-08  Kevin Kenny  <kennykb@acm.org>

	* win/tclWinInit.c (AppendEnvironment): Silenced a compilation
	warning about a type mismatch.

2004-07-07  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c (TclCompileScript): fix for [Bug 458361]. 
	Single-word scripts are compiled with an unshared cmdName to avoid
	shimmering between bytecode and cmdName reps.

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

	* generic/tclCmdMZ.c (TclMergeReturnOptions):  Simplified logic and
	removed potential memory leak.  [Bug 986257].

2004-07-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tools/man2help2.tcl (setTabs, IPmacro): Added support for the
	more advanced *roff macros used in Tk's doc/bind.n

	* generic/tclObj.c (TclInitObjSubsystem): Declare all current
	object types.

2004-07-06  Don Porter  <dgp@users.sourceforge.net>

	* tests/cmdMZ.test (cmdMZ-return-2.17):  Added a test that a word
	containing backslash-quoted value is treated correctly.

	* generic/tclCompile.c (TclWordKnownAtCompileTime):  [Bug 986196]
	Corrected flaw above and the flaw that caused TCL_TOKEN_SIMPLE_WORDs
	to have their original word value copied ( "{a b}" ) rather than the
	actual value ( "a b" ).  Thanks to Kevin Kenny for report and tests.

2004-07-06  Kevin B. Kenny  <kennykb@acm.org>

	* tests/cmdMZ.test (cmdMZ-return-2.15,cmdMZ-return-2.16):
	Added a test that a return code containing spaces is correctly
	returned.

2004-07-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tools/man2html2.tcl (IPmacro, setTabs): Added support for the
	more advanced *roff macros used in Tk's doc/bind.n

2004-07-05  Miguel Sofer <msofer@users.sf.net>

	* generic/tclBasic.c (DeleteInterpProc): fix for [Bug 983660],
	found by pspjuth. Tear down the global namespace before freeing
	the interp handle, to allow the bytecodes to free their non-shared
	literals. 
	* generic/tclLiteral.c (TclReleaseLiteral): moved special code for
	self-ref so that it is also used for non-shared literals. Possible
	bug found by inspection.

2004-07-03  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (ExprRoundFunc):
	* tests/expr-old.test (39.1): added support for wide integers to
	round(); [Bug 908375], reported by Hemang Lavana. 

2004-07-03  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.h:
	* generic/tclInt.decls:
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c: Moved declaration of TclCompEvalObj()
	from tclCompile.h to the internal stubs table, for compiler
	experimentation. 

2004-07-02  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/regcomp.c (stid): correct minor pointer size error

	* generic/tclPipe.c (TclCreatePipeline): applied TIP #202 patch
	* doc/exec.n, tests/exec.test:           that adds 2>@1 as a
	special case redirection of stderr to the result output.

2004-07-02  Kevin B. Kenny  <kennykb@acm.org>

	* tests/io.test: Changed several tests to run the event
	loop rather than just calling [update] periodically, avoiding
	intermittent failures (usually in io-29.32) that stemmed from 
	unreaped processes on Windows.
	* tests/winPipe.test (winpipe-1.11): Fixed a bug that caused
	test to fail if the path name of the working directory contained
	whitespace [Bug 678430]

2004-07-01  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/fileSystem.test: Added test for [Bug 970529]

2004-07-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* win/README.binary, win/README: Updated references to Tcl and Tk
	8.4 to point to 8.5 instead.  Thanks to Theo Verelst for spotting
	this.
	* generic/tcl.h: Added note to help prevent those changes from
	getting missed in the future.

	* doc/Namespace.3, doc/load.n, doc/Limit.3: Typo fixes and remove
	duplicate documentation. [Bug 983146]

2004-06-30  Don Porter  <dgp@users.sourceforge.net>

	* tests/fileSystem.test: Minor correction to new fileSystem-9.X
	tests so that they clean up temporary directories correctly.

2004-06-30  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/filename.n: clarified behaviour concerning trailing
	slashes in filenames [Bug 971976]

	* win/tclWinFile.c:
	* tests/fileSystem.test: fix and tests for [Bug 979879]

2004-06-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	TIP#188 IMPLEMENTATION

	* doc/string.n, tests/string.test:	 Add 'wideinteger' to things
	* generic/tclCmdMZ.c (Tcl_StringObjCmd): that can be tested for with
	the [string is] subcommand. [Patch 940915, by Kevin Kenny]

2004-06-29  Don Porter  <dgp@users.sourceforge.net>

	* win/tclWinInit.c:	Corrected reference counting flaw in
	recent changes.  Thanks to Pat Thoyts. [Bug 981893].

2004-06-29  Vince Darley  <vincentdarley@users.sourceforge.net>

	* win/tclWin32Dll.c: fix to compilation with VC++ 5.2

2004-06-29  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* library/safe.tcl: Make sure that the temporary variable is
	local to the namespace and not inadvertently global. [Bug 981733]

2004-06-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/unixNotfy.test: Modified constraints so that testing with
	a threaded tclsh (not tcltest) will not hang.

2004-06-23  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclThreadStorage.c:	Corrected type casting errors that led
	to calculation of a negative index value, thus accesses outside the
	threadStorageCache array, thus memory corruption.  Crash observed on
	Mac OS X platform.

2004-06-23  Joe Mistachkin  <joe@mistachkin.com>

	* generic/tclThread.c: Implements platform independent thread storage
	* generic/tclThreadStorage.c: mechanism and fixes associated bugs on
	platforms where there is limited thread local storage space
	(Win98/WinNT4). [Patch 976496]

	* generic/tclInt.decls:
	* generic/tclIntDecls.h: Added thread storage functions to the
	* generic/tclStubInit.c: internal stubs table.

	* unix/Makefile.in:
	* unix/configure:
	* unix/tcl.m4:
	* win/makefile.vc:
	* win/rules.vc:
	* win/Makefile.in: Modified the unix, VC++, and Cygwin build systems
	* win/configure: to include the new "tclThreadStorage.c" and the new
	* win/tcl.m4: USE_THREAD_STORAGE define.

2004-06-23  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* tests/io.test: Added -force to 18.1 and 18.2. This was failing
	on WinXP.

	* tests/winFCmd.test: Added a cleanup to winFCmd-16.11 to avoid a
	failure in 16.12.

	* tests/eofchar.data: Added -kb option to ensure a binary checkout
	to win32 systems. This fixes a failure in io-61.1

	* win/makefile.vc: fix for bug #977369 about launching tclsh to
	generate a tclConfig.sh with the nmake build system

2004-06-23  Kevin B. Kenny  <kennykb@acm.org>

	* tests/winDde.test (createChildProcess): Added a 200-ms delay
	(with the event loop live) when shutting down the test DDE server
	process, With the delay in place, nuisance failures of tests
	winDde-4.2, -6.5, and -6.6 appear to be much less frequent.
	[Bug #957449]

2004-06-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/*.test: Standardize use of platform constraints.

	* unix/tclUnixInit.c (GetStackSize, TclpCheckStackSpace): 
	* unix/tclUnixThrd.c (TclpThreadGetStackSize): Added code to check
	whether the C stack is about to be exceeded, from [Patch 746378]
	by Joe Mistachkin but with substantial revisions.

2004-06-22  Kevin Kenny  <kennykb@acm.org>

	* generic/tclEvent.c (NewThreadProc): Fixed broken build on
	Windows caused by missing TCL_THREAD_CREATE_RETURN.

	* tests/stack.test (stack-3.1): Corrected nuisance error in
	threaded builds.

2004-06-22  Zoran Vasiljevic <vasiljevic@users.sf.net>

	* generic/tclEvent.c:
	* generic/tclInt.h:
	* unix/tclUnixNotfy.c:
	* unix/tclUnixThrd.c:
	* win/tclWinThrd.c: [Bug #770053]. See bug report for
	more information about what it does.

	* tests/unixNotfy.test: rewritten to use tcltest::threadReap
	to gracefully wait for the test thread to exit. Otherwise
	we got a race condition with main thread exiting before the
	test thread. This exposed the long-standing Tcl lib issue
	with resource garbage-collection on application exit.

2004-06-21  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWin32Dll.c (DllMain, _except_dllmain_detach_handler,
	TclpCheckStackSpace, _except_checkstackspace_handler,
	TclWinCPUID, _except_TclWinCPUID_detach_handler):
	* win/tclWinChan.c (Tcl_MakeFileChannel,
	_except_makefilechannel_handler):
	* win/tclWinFCmd.c (DoRenameFile,
	_except_dorenamefile_handler, DoCopyFile,
	_except_docopyfile_handler):
	Rework pushing of exception handler function pointer
	so that compiling with gcc -O3 works. Remove empty
	function call to avoid compiler warning. Mark the
	DllMain function as noinline to avoid compiler
	error from duplicated asm labels in generated code.

2004-06-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclThreadAlloc.c (Ptr2Block): Rewrote so as to maximize
	the chance of detecting and reporting a memory inconsistency without
	relying on things being consistent. [Bug 975895]

2004-06-18  Don Porter  <dgp@users.sourceforge.net>

	* tests/load.test:	Relaxed strictness of error message matching
	for test load-2.3 so that it will pass on Mac OSX.

	* generic/tclEncoding.c: Static TclFindEncodings -> FindEncodings.
	* generic/tclInt.h:	Updated TclpFindExecutable() so that failed
	* generic/tclUtil.c:	attempts to find the executable are saved
	* unix/tclUnixFile.c:	just as successful finds are.  [Patch 966053]
	* unix/tclUnixTest.c:

2004-06-18  Kevin B. Kenny  <kennykb@acm.org>

	* tests/winFCmd.test (winFCmd-16.12): Changed test to
	compute the target directory, so as not to fail if the
	user's HOME isn't the root.

2004-06-19  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4: autoconf 2.5 fixes in Darwin section.
	* unix/configure: autoconf-2.57

2004-06-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tclUnixInit.c (localeTable): Added some more locale to
	encoding mapping info from Jim Huang <jserv@kaffe.org>

	* generic/tclInt.h (PendingObjData,TclFreeObjMacro,etc): 
	* generic/tclObj.c (TclFreeObj): Added scheme for making TclFreeObj()
	avoid blowing up the C stack when freeing up very large object
	trees. [Bug 886231]

	* win/tclWinInit.c (SetDefaultLibraryDir): Fix logic, simplify and
	add comments.

2004-06-17  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclObj.c:	Added missing space in panic message.

	* win/tclWinInit.c:	Inform [tclInit] about the default library
	directory via the ::tclDefaultLibrary variable.  This should correct
	a problem with my 2004-06-11 commit.  Better solutions still in the
	works.  Thanks to Joe Mistachkin for pointing out the breakage.

2004-06-16  Don Porter  <dgp@users.sourceforge.net>

	* doc/library.n:	Moved variables ::auto_oldpath and
	* library/auto.tcl:	::unknown_pending into ::tcl namespace.
	* library/init.tcl:	[Bugs 808319, 948794]

2004-06-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/binary.n: Added some notes to the documentation of the 'a'
	format to address the point raised in [RFE 768852].

2004-06-15  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclConfig.sh.in (TCL_EXTRA_CFLAGS): set to @CFLAGS@, which
	is the configure-time CFLAGS. Addendum to m4 change on 2004-05-26.

2004-06-14  Kevin Kenny  <kennykb@acm.org>

	* win/Makefile.in: Corrected compilation flags for tclPkgConfig.c
	so that it doesn't require Stubs.
	* generic/tclBasic.c (Tcl_CreateInterp): Removed comment stating
	that TclInitEmbeddedConfigurationInformation needs Stubs; with the
	change above, the comment is now erroneous.

2004-06-11  Don Porter  <dgp@users.sourceforge.net>

	* doc/Encoding.3:	Removed bogus claims about tcl_libPath.

	* generic/tclInterp.c (Tcl_Init):	Stopped setting the
	tcl_libPath variable.  [tclInit] can get all its directories
	without it.

	* tests/unixInit.test:	Modified test code that made use of
	tcl_libPath variable.

	* unix/tclUnixInit.c:	Stopped setting the tclDefaultLibrary variable,
	execept on the Mac OS X platform with HAVE_CFBUNDLE.  In that
	configuration we should seek some way to make use of the TIP 59
	facilities and get rid of that usage of tclDefaultLibrary as well.

	* generic/tclInterp.c:	Updated [tclInit] to make $env(TCL_LIBRARY) an
	absolute path, and to include the scriptdir,runtime configuration value
	on the search path for init.tcl.

	* unix/tclUnixInit.c:	The routines Tcl_Init() and TclSourceRCFile()
	* win/tclWinInit.c:	had identical implementations for both win and
	* generic/tclInterp.c:	unix.  Moved to a single generic implementation.
	* generic/tclMain.c:
	* library/init.tcl:
	* generic/tclInitScript.h (removed):
	* unix/Makefile.in:
	* win/tcl.dsp:

	* unix/configure.in:	Updated TCL_PACKAGE_PATH value to
	* win/configure.in:	handle --libdir configuration.

	* unix/configure.in:	autoconf-2.57
	* win/configure.in:

	* generic/tclBasic.c (Tcl_CreateInterp): Moved call to
	TclInitEmbeddedConfigurationInformation() earlier in
	Tcl_CreateInterp() so that other parts of interp creation
	and initialization may access and use the config values.

2004-06-11  Kevin Kenny  <kennykb@acm.org>

	* win/tclAppInit.c: Restored the 'setargv' procedure when
	compiling with mingw.  Apparently, the command line parsing in
	mingw doesn't work as well as that in vc++, and the result was
	(1) that winPipe-8.19 failed, and (2) that 'make test' would
	work at all only with TESTFLAGS='-singleproc 1'. [Bug 967195]

2004-06-10  Zoran Vasiljevic <vasiljevic@users.sf.net>

	* generic/tclIOUtil.c: removed forceful setting of the
	  private cached current working directory rep from 
	  within the Tcl_FSChdir(). We delegate this task to
	  the Tcl_FSGetCwd() which does this task anyway.
	  The relevant code is still present but disabled 
	  temporarily until the change proves correct. The Tcl
	  test suite passes all test with the given change so
	  I suppose it is good enough.

2004-06-10  Don Porter  <dgp@users.sourceforge.net>

	* unix/tclUnixInit.c (TclpInitLibraryPath):	Disabled addition of
	* win/tclWinInit.c (TclpInitLibraryPath):	relative-to-executable
	directories to the library search path.  A first step in reform of
	Tcl's startup process.

	***POTENTIAL INCOMPATIBILITY***
	Attempts to directly run ./tclsh or ./tcltest out of a build
	directory will either fail, or will make use of an installed
	script library in preference to the one in the source tree.
	Use `make shell` or `make runtest` instead.

	* tests/unixInit.test:  Modified tests to suit above changes.

	* generic/tclPathObj.c:	Corrected [file tail] results when operating
	on a path produced by TclNewFSPathObj(). [Bug 970529]

2004-06-09  Zoran Vasiljevic <vasiljevic@users.sf.net>

	* generic/tclIOUtil.c: partially corrected [Bug 932314].
	  Also, corrected return values of Tcl_FSChdir() to 
	  reflect those of the underlying platform-specific call.
	  Originally, return codes were mixed with those of Tcl.

2004-06-08  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c: 
	* generic/tclExecute.c: handle warning [Bug 969066]

2004-06-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclHash.c (RebuildTable): Move declaration of variable
	so it is only declared when it is used. [Bug 969068]

2004-06-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/lsearch.n: Added correct option to example. [Bug 968219]

2004-06-05  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tcl.h: Corrected Tcl_WideInt declarations so that the mingw
	build works again.
	* generic/tclDecls.h:			Changes to the tests for
	* generic/tclInt.decls:			clock frequency in
	* generic/tclIntDecls.h:		Tcl_WinTime
	* generic/tclIntPlatDecls.h:		so that any clock frequency
	* generic/tclPlatDecls.h:		is accepted provided that
	* generic/tclStubInit.c:		all CPU's in the system share
	* tests/platform.test (platform-1.3):	a common chip, and hence,
	* win/tclWin32Dll.c (TclWinCPUID):	presumably, a common clock.
	* win/tclWinTest.c (TestwincpuidCmd)	This change necessitated a 
	* win/tclWinTime.c (Tcl_GetTime):	small burst of assembly code 
	to read CPU ID information, which was added as TclWinCPUID in the
	internal Stubs.  To test this code in the common case of a
	single-processor machine, a 'testwincpuid' command was added to
	tclWinTest.c, and a test case in platform.test.  Thanks to Jeff
	Godfrey and Richard Suchenwirth for reporting this bug. [Bug
	#976722]

2004-06-04  Don Porter  <dgp@users.sourceforge.net>

	* generic/tcl.h:	Restored #include <stdio.h> to tcl.h,
	rejecting the "fix" for "Bug" 945570.  Tcl_FSSeek() needs the
	values of SEEK_SET, etc. and too many extensions rely on tcl.h
	providing stdio.h for them.

2004-06-02  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinFile.c (TclpFindExecutable): when using
	GetModuleFileNameA (Win9x), convert from CP_ACP to WCHAR then
	convert back to utf8.  Adjunct to 2004-04-07 fix.

2004-06-02  David Gravereaux <davygrvy@pobox.com>

	* tests/winPipe.test (winpipe-6.1): blocking set to 1 before
	closing to ensure we get an exitcode.  The windows pipe channel
	driver doesn't differentiate between a blocking and non-blocking
	close just yet, but will soon.  Part of [Bug 947693]

2004-06-02  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/file.n: fix to documentation of 'file volumes' (Bug 962435)

2004-06-01  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc: check for either MSDEVDIR or MSVCDIR being in
	the environment, for VC7.  [Bug 942214]

	* generic/tclIO.c (Tcl_SetChannelOption):  -buffersize wasn't
	understanding hexidecimal notation nor was reporting number
	conversion errors.  The behavior to silently ignore settings
	outside the acceptable range of Tcl_SetChannelBufferSize
	(<10 or >1M) is unchanged.  This silent ignoring behavior
	might be up for review soon..

2004-05-30  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinPipe.c:
	* win/tclWinPort.h:  Reworked the win implementation of
	Tcl_WaitPid to support exitcodes in the 'signed short' range.
	Even though this range is non-portable, it is valid on windows.
	Detection of exception codes are now more accurate.  Previously,
	an application that exited with ExitProcess((DWORD)-1); was
	improperly reported as exiting with SIGABRT.

2004-05-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInterp.c: Added comments describing the purposes of
	each function in the limit implementation and rewrote the names of
	some non-public functions for greater clarity of purpose.
	* doc/interp.n: Added note about what happens when a limited
	interpreter creates a slave interpreter.
	* doc/Limit.3: Added manual page for the resource limit
	subsystem's C API. [Bug 953903]

2004-05-29  Joe English  <jenglish@users.sourceforge.net>

	* doc/global.n, doc/interp.n, doc/lrange.n:
	Fix minor markup errors.

2004-05-28  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/*.n: Added examples to many (too many to list) more man pages.

2004-05-25  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c:
	* generic/tclVar.c: using (ptrdiff_t) instead of (int) casting to
	correct compiler warnings [Bug 961657], reported by Bob Techentin.

2004-05-27  Kevin B. Kenny  <kennykb@acm.org>

	* tests/clock.test: Added a single test for the presence of %G
	in [clock format], and conditioned out the clock-10.x series if
	they're all going to fail because of a broken strftime() call.
	[Bug 961714]

2004-05-27  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclHash.c (CompareStringKeys): Added #ifdef to allow
	people to instruct this function to use strcmp(). [FRQ 951168]

	* generic/tclVar.c: Moved declarations into #if guards so they
	only happen when required.
	* unix/tclUnixPort.h: Guard declaration of strtod() so it is only
	enabled when we don't have a declaration in stdlib.h
	* unix/tclUnixThrd.c (Tcl_CreateThread):	Added declarations
	* unix/tclUnixTest.c (AlarmHandler):		and casts so that
	* unix/tclUnixChan.c (TtyModemStatusStr):	all functions are
	* generic/tclScan.c (Tcl_ScanObjCmd):		defined before use
	* generic/tclDictObj.c (InvalidateDictChain):	and no cross-type
	* generic/tclCmdMZ.c (Tcl_StringObjCmd):	uses are performed.

	The overall effect is to make building with gcc with the
	additional flags -Wstrict-prototypes -Wmissing-prototypes produce
	no increase in the total number of warnings (except for main(),
	which is undeclared for traditional reasons.)

2004-05-26  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/Makefile.in:  Rework configure ordering to TCL_LINK_LIBS,
	* unix/tcl.m4:       ENABLE_SHARED, CONFIG_CFLAGS, & ENABLE_SYMBOLS
	* unix/configure:    before TCL_EARLY_FLAGS and TCL_64BIT_FLAGS
	* unix/configure.in: (about 400 lines earlier) in configure.in.
	This forces CFLAGS configuration to be done before many tests,
	which is needed for 64-bit builds and may affect other builds.
	Also make CONFIG_CFLAGS append to CFLAGS directly instead of using
	EXTRA_CFLAGS, and have LDFLAGS append to any existing value.
	[Bug #874058]
	* unix/dltest/Makefile.in: change EXTRA_CFLAGS to DEFS

2004-05-26  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:	Correction to debug prints and testing
	* library/tcltest/pkgIndex.tcl:	if TCLTEST_OPTIONS value.  Corrected
	* tests/tcltest.test:		double increment of numTestFiles in
	-singleproc 1 configurations.  Updated tcltest-19.1 to tcltest 2.1
	behavior.  Corrected tcltest-25.3 to not falsely report a failure
	in tcltest.test.  Bumped to tcltest 2.2.6.  [Bugs 960560, 960926]

2004-05-25  Jeff Hobbs  <jeffh@ActiveState.com>

	* doc/http.n (http::config): add -urlencoding option (default utf-8)
	* library/http/http.tcl:     that specifies encoding conversion of
	* library/http/pkgIndex.tcl: args for http::formatQuery.  Previously
	* tests/http.test:           undefined, RFC 2718 says it should be
	utf-8. 'http::config -urlencoding {}' returns previous behavior,
	which will throw errors processing non-latin-1 chars.
	Bumped http package to 2.5.0.

2004-05-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInterp.c (DeleteScriptLimitCallback): Move all
	deletion of script callback hash table entries to happen here so
	the entries are correctly removed at the right time.  [Bug 960410]

2004-05-25  Miguel Sofer <msofer@users.sf.net>

	* docs/global.n: added details for qualified variable names 
	[Bug 959831]

2004-05-25  Miguel Sofer <msofer@users.sf.net>

	* generic/tclNamesp.c (Tcl_FindNamespaceVar):
	* tests/namespace.test (namespace-17.10-12): reverted commit of
	2004-05-23 and removed the tests, as it interferes with the
	varname resolver and there are apps that break (AlphaTk). A fix
	will have to wait for Tcl9.

	* generic/tclVar.c: Caching of namespace variables disabled: no
	simple way was found to avoid interfering with the resolver's idea
	of variable existence. A cached varName may keep a variable's name
	in the namespace's hash table, which is the resolver's criterion
	for existence.

	* tests/namespace.c (namespace-17.10): testing for interference
	between varname caching and name resolver.

2004-05-25  Kevin Kenny  <kennykb@acm.org>

	* tests/winFCmd.test: Correct test for the presence of a CD-ROM so
			      that it doesn't misdetect some other sort
			      of filesystem with a write-protected root as
			      being a CD-ROM drive. [Bug 918267]

2004-05-25  Don Porter  <dgp@users.sourceforge.net>

	* tests/winPipe.test:	Protect against path being set 
	* tests/unixInit.test:	Unset path when done.
	* tests/unload.test (unload-3.1): Verify [pkgb_sub] does not exist.
	Delete interps when done.
	* tests/stringComp.test:	stop re-use of string.test test names
	* tests/regexpComp.test:	stop re-use of regexp.test test names
	* tests/namespace.test (namespace-46.3): Verify [p] does not exist.
	* tests/http.test:	Clear away the custom [bgerror] when done.
	* tests/io.test:	Take care to use namespace variables.
	* tests/autoMkindex.test (autoMkindex-5.2): Use variable "result"
	that gets cleaned up.
	* tests/exec.test:	Clean up the "path" array.
	* tests/interp.test (interp-9.3): Initialize res, so prior values
	cannot make the test fail.
	* tests/execute.test (execute-8.1):  Updated to remove the trace
	set on ::errorInfo .  When left in place, that trace can cause
	later tests to fail.

2004-05-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclBasic.c: Removed references to Tcl_RenameCommand from
	* generic/tcl.h:      comments. [Bug 848440, second part]

	* tests/fCmd.test: Rewrote tests that failed consistently on NFS
	so they either succeed (through slightly more liberal matching of
	the results) or are constrained to not run. [Bug 931312]

	* doc/bgerror.n: Use idiomatic open flags for working with log
	files.  [Bug 959602]

2004-05-24  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclExecute.c (VerifyExprObjType): use GET_WIDE_OR_INT to
	properly have tclIntType used for smaller values.  This corrects
	TclX bug 896727 and any other 3rd party extension that created
	math functions but was not yet WIDE_INT aware in them.

2004-05-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInterp.c (TclInitLimitSupport): Made limits work on
	platforms where sizeof(void*)!=sizeof(int). [Bug 959193]

2004-05-24 Miguel Sofer <msofer@users.sf.net>

	* doc/set.n: accurate description of name resolution process,
	referring to namespace.n for details [Bug 959180]

2004-05-23  Miguel Sofer <msofer@users.sf.net>

	* generic/tclNamesp.c (Tcl_FindNamespaceVar): [Bug 959052] fixed,
	insuring that no "zombie" variables are found.
	* generic/tclVar.c (TclLookupSimpleVar): comments re [Bug 736729] 
	(predecessor of [Bug 959052]) removed.
	* tests/namespace.test: added tests 17.10-12 

	The patch modifies non-documented behaviour, and passes every test
	in the testsuite. However, scripts relying on the old behaviour
	may break.
	Note that the only behaviour change concerns the creative writing
	of unset variables. More precisely, which variable will be created
	when neither a namespace variable nor a global variable by that
	name exists, as defined by [info vars]. The new behaviour is that
	the namespace resolution process deems a variable to exist exactly
	when [info vars] finds it - ie, either it has value, or else it
	was "fixed" by a call to [variable].
	Note: this patch was removed on 2002-05-25. 

2004-05-22  Miguel Sofer <msofer@users.sf.net>

	* generic/tclVar.c (TclObjLookupVar, TclObjUnsetVar2): fix for new
	(in tcl8.4) exteriorisations of [Bug 736729] due to the use of
	tclNsVarNameType obj types. Reenabling the use of this objType
	("VAR ref absolute" benchmark down to 66 ms, from 230). 
	Added comments in TclLookupSimpleVar explaining my current
	understanding of [Bug 736729].

2004-05-22  Miguel Sofer <msofer@users.sf.net>

	* generic/tclVar.c: fix for [Bug 735335]. The use of
	tclNsVarNameType objs is still disabled, pending resolution of
	[Bug 736729].

2004-05-21  Miguel Sofer <msofer@users.sf.net>

	* tests/namespace.test (namespace-41.3): removed the {knownBug}
	constraint: [Bug 231259] is closed since nov 2001, and the fix of 
	[Bug 729692] (INST_START_CMD) makes the test succeed.

2004-05-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): Move a few
	declarations a short distance so pre-C99 compilers can cope.  Also
	fix so TCL_COMPILE_DEBUG path compiles...

2004-05-21  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (TclExecuteByteCode): reorganised TEBC
	automatic variables, defining them in tight blocks instead of at
	the function level. This has three purposes:
	- it simplifies the analysis of individual instructions
	- it is preliminary work to the non-recursive engine
	- it allows a better register allocation by the optimiser; under
	gcc3.3, this results in up to 10% runtime in some tests

2004-05-20  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInterp.c (TclLimitRemoveAllHandlers): 
	* generic/tclBasic.c (DeleteInterpProc): 
	* tests/interp.test (interp-34.7): 
	Ensure that all limit callbacks are deleted when their interpreters
	are deleted. [Bug 956083]

2004-05-19  Kevin B. Kenny  <kennykb@acm.org>

	* win/tclWinFile.c (TclpMatchInDirectory): fix for an issue
	where there was a sneak path from Tcl_DStringFree to
	SetErrorCode(0). The result was that the error code could
	be reset between a call to FindFirstFileEx and the check
	of its status return, leading to a bizarre error return of
	{POSIX unknown {No error}}.  (Found in unplanned test -
	no incident logged at SourceForge.)

2004-05-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/interp.test (interp-34.3): Rewrite this test to see if a
	time limit can catch a tight bytecode loop, a maximally aggressive
	denial-of-service attack.
	* generic/tclInterp.c (Tcl_LimitCheck): Fix the sense of checks to
	see whether a time limit has been extended.

	* tests/*.test: Many minor fixes, including ensuring that every
	test is run (so constraints control whether the test is doing
	anything) and making sure that constraints are always set using
	the API instead of poking around inside tcltest's internal
	datastructures.  Also got rid of all trailing whitespace lines
	from the test suite!

2004-05-19  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c: Fixed [SF Tcl Bug 943274]. This is the same problem
	* generic/tclIO.h: as [SF Tcl Bug 462317], see ChangeLog entry
		   2001-09-26. The fix done at that time is incomplete. It
		   is possible to get around it if the actual read
		   operation is defered and not executed in the event
		   handler itself. Instead of tracking if we are in an
		   read caused by a synthesized fileevent we now track if
		   the OS has delivered a true event = actual data and
		   bypass the driver if a read finds that there is no
		   actual data waiting. The flag is cleared by a short or
		   full read.

	  ***POTENTIAL INCOMPATIBILITY*** for channel drivers.

2004-05-17  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: fix to (Bug 956063) in 'file dirname'.
	* tests/cmdAH.test: added test for this bug.

	* doc/FileSystem.3: better documentation of refCount requirements 
	of some FS functions (Bug 956126)

2004-05-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclTest.c (TestgetintCmd): Made the tests in get.test check
	* tests/get.test:		     Tcl_GetInt() since the core now
					     avoids that function.

2004-05-18  Kevin B. Kenny  <kennykb@acm.org>

	* compat/strftime.c (_fmt, ISO8601Week):
	* doc/clock.n:
	* tests/clock.test: Major rework to the handling of ISO8601
	week numbers.  Now passes all the %G and %V test cases on
	Windows, Linux and Solaris [Bugs #500285, #500389, and #852944]

2004-05-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/append.n, doc/upvar.n: Added example.

2004-05-18  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc: now generates a tclConfig.sh from Pat Thoyts
	[Patch 909911]

2004-05-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/lsearch.n: Improve clarity (based on [Patch 955361] by Peter
	Spjuth)

	* tools/man2help2.tcl (macro,SHmacro): Added support for
	subsection (.SS) header macros.

	* doc/interp.n: Added user documentation for the TIP#143 resource
	limits and some examples.

	* generic/tclInterp.c (Tcl_LimitCheck, Tcl_LimitTypeReset): Reset
	the limit-exceeded flag when removing a limit.

2004-05-18  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (TclExecuteByteCode): added comments to
	classify the variables according to their use in TEBC.

2004-05-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/global.n, doc/uplevel.n: Added an example.

	* tests/info.test (info-3.1): Corrected test result back to what
	it used to be in Tcl 7.* now that command counts are being
	correctly kept.

	* generic/tclExecute.c (TEBC:INST_START_CMD): Make sure that the
	command-count is always advanced.  Allows TIP#143 limits to tell
	that work is being done.

	* doc/list.n: Updated example to fit with the unified format.
	* doc/seek.n: Added some examples.

2004-05-17  Vince Darley  <vincentdarley@users.sourceforge.net>

	* win/tclWinFile.c:
	* tests/cmdAH.test: fix to (Bug 954263) where 'file executable'
	was case-sensitive.

2004-05-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/OpenFileChnl.3: Documented type of 'offset' argument to
	Tcl_Seek was wrong. [Bug 953374]

2004-05-16  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (TclExecuteByteCode): remove one level of
	indirection for compiledLocals addressing.

2004-05-16  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (INST_CALL_FUNC1): bugfix; restored
	(DE)CACHE_STACK_INFO pair around the call - the user defined math
	function could cause a recursive call to TEBC.

2004-05-16  Miguel Sofer <msofer@users.sf.net>

	* generic/tclBasic.c (Tcl_DeleteInterp):
	* generic/tclExecute.c (INST_START_CMD): interp deletion now
	modifies the compileEpoch, eliminating the need for the check for
	interp deletion in INST_START_CMD.

2004-05-16  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.h:
	* generic/tclCompile.c:
	* generic/tclExecute.c: changed implementation of {expand}, last
	chance while in alpha as ...

	***POTENTIAL INCOMPATIBILITY***
	Scripts precompiled with ProComp under previous tcl8.5a versions
	may malfunction due to changed instruction numbers for
	INST_LIST_INDEX_IMM, INST_LIST_RANGE_IMM and INST_START_CMD. 

2004-05-14  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclInt.decls:      Promoted TclpLocaltime and TclpGmtime
	* generic/tclIntDecls.h:     from Unix-specific stubs to the generic
	* generic/tclIntPlatDecls.h: internal Stubs table.  Reran 'genstubs'
	* generic/tclStubInit.c:
	* unix/tclUnixPort.h:

	* generic/tclClock.c: Changed a buggy 'GMT' timezone specification
			      to the correct 'GMT0'. [Bug #922848]

	* unix/tclUnixThrd.c: Moved TclpGmtime and TclpLocaltime to
			      unix/tclUnixTime.c where they belong.

	* unix/tclUnixTime.c (TclpGmtime, TclpLocaltime, TclpGetTimeZone,
			      ThreadSafeGMTime [removed],
			      ThreadSafeLocalTime [removed],
			      SetTZIfNecessary, CleanupMemory):
	    Restructured to make sure that the same mutex protects
	    all calls to localtime, gmtime, and tzset.	Added a check
	    in front of those calls to make sure that the TZ env var
	    hasn't changed since the last call to tzset, and repeat
	    tzset if necessary. [Bug #942078]  Removed a buggy test
	    of the Daylight Saving Time information in 'gettimeofday'
	    in favor of applying 'localtime' to a known value.
	    [Bug #922848]

	* tests/clock.test (clock-3.14): Added test to make sure that
	    changes to $env(TZ) take effect immediately.

	* win/tclWinTime.c (TclpLocaltime, TclpGmtime):
	    Added porting layer for 'localtime' and 'gmtime' calls.

2004-05-14  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c:
	* generic/tclCompile.h: the math functions receive a pointer to
	top of the stack (tosPtr) instead of the execution environment
	(eePtr). First step towards a change in the execution stack
	management - it is now only used within TEBC.

2004-05-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	TIP#143 IMPLEMENTATION

	* generic/tclExecute.c (TclCompEvalObj, TclExecuteByteCode): 
	* generic/tclBasic.c (TclEvalObjvInternal): Enable limit checking.
	* generic/tclInterp.c (Tcl_Limit*): Public limit API.
	* generic/tcl.decls: 
	* tests/interp.test: Basic tests of command limits.

	* doc/binary.n:		TIP#129 IMPLEMENTATION [Patch 858211]
	* generic/tclBinary.c:	Note that the test suite probably has many more
	* tests/binary.test:	failures now due to alterations in constraints.

2004-05-12  Miguel Sofer <msofer@users.sf.net>

	Optimisations for INST_START_CMD [Bug 926164].
	* generic/tclCompile.c (TclCompileScript): avoid emitting
	INST_START_CMD as the first instruction in a bytecoded Tcl_Obj. It
	is not needed, as the checks are done before calling TEBC.
	* generic/tclExecute.c (TclExecuteByteCode): runtime peephole
	optimisation: check at INST_POP if the next instruction is
	INST_START_CMD, in which case we fall through.

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

	* doc/split.n, doc/join.n: Updated examples and added more.

2004-05-11  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/glob.n: documented behaviour of symbolic links with 
	'glob -types d' (Bug 951489)

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

	* doc/scan.n: Updated the examples to be clearer about their
	relevance to the scan command.

2004-05-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/scan.n: Added examples.

2004-05-10  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinPipe.c (BuildCommandLine): Moved non-obvious appending
	logic to outside the loop and added commentary for its purpose. Also
	use the existence of contents in the linePtr rather than the scratch
	DString post the append, as this more clear.

	(TclpCreateProcess): When under NT, with no console, and executing a
	DOS application, the path priming does not need an ending space as
	BuildCommandLine() will do this for us.

2004-05-08  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c: 
	* generic/tclIOUtil.c: remove some compiler warnings on MacOS X.

2004-05-07  Chengye Mao <chengye.geo@yahoo.com>

	* win/tclWinPipe.c: refixed bug 789040 re-entered in rev 1.41.
	Let's be careful and don't re-enter previously fixed bugs.

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

	* doc/format.n: Added examples.

2004-05-07  Miguel Sofer <msofer@users.sf.net>

	* doc/unset.n: added upvar.n to the "see also" list

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

	* generic/tclEncoding.c: 
	* tests/encoding.test: added support and tests for translating
	embedded null characters between real nullbytes and the internal
	representation on input/output (Bug #949905).

2004-05-07  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c: 
	* generic/tclIOUtil.c: 
	* generic/tclFileSystem.h:
	* tests/fileSystem.test: fix for [Bug 943995], in which vfs-
	registered root volumes were not handled correctly as glob
	patterns in all circumstances.

2004-05-06  Miguel Sofer <msofer@users.sf.net>

	* generic/tclInt.h:
	* generic/tclObj.c (TclFreeObj): made TclFreeObj use the new macro
	TclFreeObjMacro(), so that the allocation and freeing of Tcl_Obj
	is defined in a single spot (the macros in tclInt.h), with the
	exception of the TCL_MEM_DEBUG case.
	The #ifdef logic for the corresponding macros has been reformulated
	to make it clearer.

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

	* doc/break.n, doc/continue.n, doc/for.n, doc/while.n: More examples.

2004-05-05  Don Porter  <dgp@users.sourceforge.net>

	* tests/unixInit.test (unixInit-2.10):	Test correction for Mac OSX.
	Be sure to consistently compare normalized path names.  Thanks to
	Steven Abner (tauvan).  [Bug 948177]

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

	* doc/CrtObjCmd.3: Remove reference to Tcl_RenameCommand; there is
	no such API. [Bug 848440]

2004-05-05  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinSock.c (SocketEventProc) : connect errors should
	fire both the readable and writable handlers because this is
	how it works on UNIX [Bug 794839]

	* generic/tclEncoding.c (TclFinalizeEncodingSubsystem):
	FreeEncoding(systemEncoding); moved to before the hash table
	itereation as it was causing a double free attempt under some
	conditions.

	* win/coffbase.txt: Added the tls extension to the list of
	preferred load addresses.

2004-05-04  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/fileSystem.test (filesystem-1.39): replace 'file volumes'
	* tests/fileName.test (filename-12.9,10):  lindex with direct C:/
	hard-coded because A:/ was being used and that is empty for most.

	* tests/winFCmd.test (winFCmd-16.12): test volumerelative $HOME

2004-05-04  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclAlloc.c:		Make sure Tclp*Alloc* routines get
	* generic/tclInt.h:		declared in the TCL_MEM_DEBUG and
	* generic/tclThreadAlloc.c:	TCL_THREADS configuration. [Bug 947564]

	* tests/tcltest.test:	Test corrections for Mac OSX.  Thanks
	to Steven Abner (tauvan).  [Bug 947440]

2004-05-04  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclEvent.c (TclSetLibraryPath): Suppress a warning.

2004-05-03  Andreas Kupries  <andreask@activestate.com>

	* Applied [SF Tcl Patch 868853], fixing a mem leak in
	  TtySetOptionProc. Report and Patch provided by Stuart
	  Cassoff <stwo@users.sf.net>.

2004-05-03  Miguel Sofer <msofer@users.sf.net>

	* generic/tclProc.c (TclCreateProc): comments corrected.

2004-05-03  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c (TclCompileScript): setting the compilation
	namespace outside of the loop.

2004-05-03  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c:
	* generic/tclInt.h: reverted fix for [Bug 926445] of 2004-04-02,
	restoring TCL_ALIGN to the header file. Todd Helfter reported that
	the macro is required by tbcload.

2004-05-03  Kevin Kenny  <kennykb@acm.org>

	* win/tclWin32Dll.c (TclpCheckStackSpace):
	* tests/stack.test (stack-3.1): Fix for undetected stack
	overflow in TclReExec on Windows. [Bug 947070]

2004-05-03  Don Porter  <dgp@users.sourceforge.net>

	* library/init.tcl:	Corrected unique prefix matching of
	interactive command completion in [unknown].  [Bug 946952]

2004-05-02  Miguel Sofer <msofer@users.sf.net>

	* generic/tclProc.c (TclObjInvokeProc):
	* tests/proc.test (proc-3.6): fix for bad quoting of multi-word
	proc names in error messages [Bug 942757]

2004-04-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/glob.n, doc/incr.n, doc/set.n:	More examples.
	* doc/if.n, doc/rename.n, doc/time.n:

2004-04-30  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.h:		Replaced Kevin Kenny's temporary
	* generic/tclThreadAlloc.c:	fix for Bug 945447 with a cleaner,
	more permanent replacement.  

2004-04-30  Kevin B. Kenny   <kennykb@acm.org>

	* generic/tclThreadAlloc.c: Added a temporary (or so I hope!)
	inclusion of "tclWinInt.h" to avoid problems when compiling
	on Win32-VC++ with --enable-threads.  [Bug 945447]

2004-04-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/puts.n: Added a few examples.

2004-04-29  Don Porter  <dgp@users.sourceforge.net>

	* tests/execute.test (execute-8.2):	Avoid crashes when there
	is limited system stack space (threads-enabled).

2004-04-28  Miguel Sofer <msofer@users.sf.net>

	* doc/global.n:
	* doc/upvar.n:
	* generic/tclVar.c (ObjMakeUpvar):
	* tests/upvar.test (upvar-8.11):
	* tests/var.test (var-3.11): Avoid creation of unusable variables:
	[Bug 600812] [TIP 184].

2004-04-28  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/lsearch.n: Fixed fault in documentation of -index option [943448]

2004-04-26  Don Porter  <dgp@users.sourceforge.net>

	* unix/tclUnixFCmd.c (TclpObjNormalizePath):  Corrected improper
	positioning of returned checkpoint.  [Bug 941108]

2004-04-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/open.n, doc/close.n: Updated (thanks to David Welton) to be
	clearer about pipeline errors and added example to open(n) that shows
	simple pipeline use.  [Patches 941377,941380]

	* doc/DictObj.3: Added warning about the use of Tcl_DictObjDone and an
	example of use of iteration. [Bug 940843]

	* doc/Thread.3: Reworked to remove references to testing interfaces
	and instead promote the use of the Thread package. [Patch 932527]
	Also reworked and reordered the page for better readability.

2004-04-25  Don Porter  <dgp@users.sourceforge.net>

	* generic/tcl.h:	Removed obsolete declarations and #include's.
	* generic/tclInt.h:	[Bugs 926459, 926486]

2004-04-24  David Gravereaux <davygrvy@pobox.com>

	* win/tclWin32Dll.c (DllMain): Added DisableThreadLibraryCalls()
	for the DLL_PROCESS_ATTACH case.  We're not interested in knowing
	about DLL_THREAD_ATTACH, so disable the notices.

2004-04-24  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclPort.h:
	* macosx/Makefile:
	* unix/Makefile.in: followup on tcl header reform [FR 922727]:
	removed use of relative #include paths in tclPort.h to allow
	installation of private headers outside of tcl source tree; added
	'unix' dir to compiler header search path; add newly required
	tcl private headers to Tcl.framework on Mac OSX.

2004-04-23  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (Tcl_SetChannelOption): Fixed [SF Tcl Bug
	  930851]. When changing the eofchar we have to zap the related
	  flags to prevent them from prematurely aborting the next read.

2004-04-25  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: fix to [Bug 940281].  Tcl_FSJoinPath
	will now always return a valid Tcl_Obj when the input is valid.
	* generic/tclIOUtil.c: fix to [Bug 931823] for a more consistent
	Tcl_FSPathSeparator() implementation which allows filesystems
	not to implement their Tcl_FSFilesystemSeparatorProc if they
	wish to use the default '/'.  Also fixed associated memory leak
	seen with, e.g., tclvfs package.
	* doc/FileSystem.3: documented Tcl_FSJoinPath return values
	more clearly, and Tcl_FSFilesystemSeparatorProc requirements.

2004-04-23  David Gravereaux <davygrvy@pobox.com>

	* win/tclWin32Dll.c:  Removed my mistake from 4/19 of adding an
	exit handler to TclWinInit.  TclWinEncodingsCleanup called from
	TclFinalizeFilesystem does the Tcl_FreeEncoding for us.

	* win/tclWinChan.c (Tcl_MakeFileChannel) : Case for CloseHandle
	returning zero and not throwing a
	RaiseException(EXCEPTION_INVALID_HANDLE) now being done.

2004-04-22  David Gravereaux <davygrvy@pobox.com>

	* generic/tclEvent.c: TclSetLibraryPath's use of caching the
	stringrep of the pathPtr object to TclGetLibraryPath called from
	another thread was ineffective if the original's stringrep had
	been invalidated as what happens when it gets muted to a list.

	* win/tclWinTime.c:  If the Tcl_ExitProc (StopCalibration) is
	called from the stack frame of DllMain's PROCESS_DETACH, the
	wait operation should timeout and continue.

	* generic/tclInt.h:
	* generic/tclThread.c:
	* generic/tclEvent.c:
	* unix/tclUnixThrd.c:
	* win/tclWinThrd.c:  Provisions made so masterLock, initLock,
	allocLock and joinLock mutexes can be recovered during
	Tcl_Finalize.

2004-04-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/switch.n: Reworked the examples to be more systematically
	named and to cover some TIP#75 capabilities.

	* doc/cd.n: Documentation clarification from David Welton.

	* doc/exec.n: Added some examples, Windows ones from Arjen Markus
	and Unix ones by myself.

2004-04-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/Hash.3: Added note to Tcl_{First,Next}HashEntry docs that
	deleting the element they return is supported (and is in fact the
	only safe update you can do to the structure of a hashtable while
	an iteration is going over it.)

	* doc/bgerror.n: Added example from David Welton. [Patch 939473]

	* doc/after.n: Added examples from David Welton. [Patch 938820]

2004-04-19  David Gravereaux <davygrvy@pobox.com>

	* win/tclWin32Dll.c: Added an exit handler in TclWinInit() so
	tclWinTCharEncoding could be freed during Tcl_Finalize().

	* generic/tclEncoding.c: Added FreeEncoding(systemEncoding) in
	TclFinalizeEncodingSubsystem because its ref count was incremented
	in TclInitEncodingSubsystem.

2004-04-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/read.n: Added example from David Welton. [Patch 938056]

2004-04-19  Kevin B. Kenny   <kennykb@acm.org>

	* generic/tclObj.c (Tcl_GetDoubleFromObj) Corrected
	"short circuit" conversion of int to double. Reported by
	Jeff Hobbs on the Tcl'ers Chat.

2004-04-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/lreplace.n, doc/lrange.n, doc/llength.n:	More examples for
	* doc/linsert.n, doc/lappend.n:			the documentation.

2004-04-16  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/FileSystem.3: Corrected documentation of Tcl_FSUtime, and
	the corresponding filesystem driver Tcl_FSUtimeProc. [Bug 935838]

2004-04-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/socket.n: Added example from [Patch 936245].
	* doc/gets.n: Added example based on [Patch 935911].

2004-04-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclClock.c (Tcl_ClockObjCmd): Minor fault in a [clock
	clicks] error message.

2004-04-07  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinInit.c (TclpSetInitialEncodings): note that WIN32_CE
	is also a unicode platform.
	* generic/tclEncoding.c (TclFindEncodings, Tcl_FindExecutable): 
	* generic/tclInt.h:                         Correct handling of UTF
	* unix/tclUnixInit.c (TclpInitLibraryPath): data that is actually
	* win/tclWinFile.c (TclpFindExecutable):    "clean", allowing the
	* win/tclWinInit.c (TclpInitLibraryPath):   loading of Tcl from
	paths that contain multi-byte chars on Windows [Bug 920667]

	* win/configure:    define TCL_LIB_FLAG, TCL_BUILD_LIB_SPEC,
	* win/configure.in: TCL_LIB_SPEC, TCL_PACKAGE_PATH in tclConfig.sh.

2004-04-06  Don Porter  <dgp@users.sourceforge.net>

	Patch 922727 committed.  Implements three changes:

	* generic/tclInt.h:	Reworked the Tcl header files into a clean
	* unix/tclUnixPort.h:	hierarchy where tcl.h < tclPort.h < tclInt.h 
	* win/tclWinInt.h:	and every C source file should #include
	* win/tclWinPort.h:	at most one of those files to satisfy its
	declaration needs.  tclWinInt.h and tclWinPort.h also better organized
	so that tclWinPort.h includes the Windows implementation of
	cross-platform declarations, while tclWinInt.h makes declarations that
	are available on Windows only.

	* generic/tclBinary.c (TCL_NO_MATH):	Deleted the generic/tclMath.h
	* generic/tclMath.h (removed):		header file. The internal Tcl
	* macosx/Makefile (PRIVATE_HEADERS):	header, tclInt.h, has a
	* win/tcl.dsp:				#include <math.h> directly,
	and file external to Tcl needing libm should do the same.

	* win/Makefile.in (WIN_OBJS):	Deleted the win/tclWinMtherr.c file.
	* win/makefile.bc (TCLOBJS):	It's a vestige from matherr() days
	* win/makefile.vc (TCLOBJS):	gone by.
	* win/tcl.dsp:
	* win/tclWinMtherr.c (removed):

	End Patch 922727.

	* tests/unixInit.test (unixInit-3.1):	Default encoding on Darwin
	systems is utf-8.  Thanks to Steven Abner (tauvan).  [Bug 928808]

2004-04-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/cmdAH.test (cmdAH-18.2): Added constraint because
	access(...,X_OK) is defined to be permitted to be meaningless when
	running as root, and OSX exhibits this.  [Bug 929892]

2004-04-02  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c:
	* generic/tclInt.h: removed the macro TCL_ALIGN() from tclInt.h,
	replaced by the static macro ALIGN() in tclCompile.c [Bug 926445]

2004-04-02  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.h: removed redundant #ifdef _TCLINT 
	[Bug 928415], reported by tauvan.

2004-04-02  Don Porter  <dgp@users.sourceforge.net>

	* tests/tcltest.test: Corrected constraint typos: "nonRoot" ->
	"notRoot".  Thanks to Steven Abner (tauvan).  [Bug 928353]

2004-04-01  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.h:  Removed obsolete tclBlockTime* declarations.
	[Bug 926454]

2004-04-01  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c:	 Fix to privately reported vfs bug with
	'glob -type d -dir . *' across a vfs boundary.	No tests for
	this are currently possible without effectively moving tclvfs
	into Tcl's test suite.

2004-03-31  Don Porter  <dgp@users.sourceforge.net>

	* doc/msgcat.n:	Clarified message catalog file encodings. [Bug 811457]
	* library/msgcat/msgcat.tcl:
	Updated internals to make use of [dict]s to store message catalog
	data and to use [source -encoding utf-8] to access catalog files.
	Thanks to Michael Sclenker.  [Patch 875055, RFE 811459]
	Corrected [mcset] to be able to successfully set a translation to
	the empty string.  [mcset $loc $src {}] was incorrectly set the
	$loc translation of $src back to $src.	Also changed [ConvertLocale]
	to minimally require a non-empty "language" part in the locale value.
	If not, an error raised prompts [Init] to keep looking for a valid
	locale value, or ultimately fall back on the "C" locale. [Bug 811461].
	* library/msgcat/pkgIndex.tcl:	Bump to msgcat 1.4.1.  

2004-03-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclHash.c (HashStringKey): Cleaned up. This function is
	not faster, but it is a little bit clearer.
	* generic/tclLiteral.c (HashString): Applied logic from HashObjKey.
	* generic/tclObj.c (HashObjKey): Rewrote to fix fault which hashed
	every single-character object to the same hash bucket.  The new
	code is shorter, simpler, clearer, and (happily) faster.

2004-03-30  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (TEBC): reverting to the previous method
	for async tests in TEBC, as the new method turned out to be too
	costly. Async tests now run every 64 instructions.

2004-03-30  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c:     New instruction code INST_START_CMD
	* generic/tclCompile.h:     that allows checking the bytecode's
	* generic/tclExecute.c:     validity [Bug 729692] and the interp's
	* tests/interp.test (18.9): readyness [Bug 495830] before running
	* tests/proc.test (7.1):    the command. It also changes the
	* tests/rename.test (6.1):  mechanics of the async tests in TEBC,
	doing it now at command start instead of every 16 instructions.

2004-03-30  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c:  Fix to Windows glob where the pattern is
	* generic/tclIOUtil.c:	  a volume relative path or a network
	* tests/fileName.test:	  share [Bug 898238]. On windows 'glob'
	* tests/fileSystem.test:  will now return the results of 
	'glob /foo/bar' and 'glob \\foo\\bar' as 'C:/foo/bar', i.e. a 
	correct absolute path (rather than a volume relative path).

	Note that the test suite does not test commands like 
	'glob //Machine/Shared/*' (on a network share).	 

2004-03-30  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c:	  Fix to filename bugs recently
	* tests/fileName.test:	  introduced [Bug 918320].

2004-03-29  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclMain.c (Tcl_Main, StdinProc):	Append newline only
	* tests/basic.test (basic-46.1):		to incomplete scripts
	as part of multi-line script construction.  Do not add an extra
	trailing newline to the complete script.  [Bug 833150]

2004-03-28  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c (TclCompileScript): corrected possible
	segfault when a compilation returns TCL_OUTLINE_COMPILE after
	having grown the compile environment [Bug 925121].

2004-03-27  Miguel Sofer <msofer@users.sf.net>

	* doc/array.n: added documentation for trace-realted behaviour of
	'array get' [Bug 449893]

2004-03-26  Don Porter  <dgp@users.sourceforge.net>

	* README:		Bumped version number to 8.5a2 to
	* tools/tcl.wse.in:	distinguish HEAD of CVS development
	* unix/configure.in:	from the recent 8.5a1 release.
	* unix/tcl.spec:
	* win/README.binary:
	* win/configure.in:

	* unix/configure:	autoconf-2.57

2004-03-26  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c:	  Fix to Windows-only volume relative
	* tests/fileSystem.test:  path normalization. [Bug 923568].
	Also fixed another volume relative bug found while testing.

2004-03-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclNamesp.c (NsEnsembleImplementationCmd): Fix messed up
	handling of strncmp result which just happened to work in some
	libc implementations. [Bug 922752]

2004-03-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/StringObj.3: Inverted the sense of the documentation of how
	the bytes parameter is documented to match behaviour. [Bug 921464]

	* generic/tclIntDecls.h: Made HEAD build on Solaris again by
	applying fix recommended by Don Porter.

2004-03-18  Reinhard Max  <max@suse.de>

	* generic/tclIntDecls.h: Removed TclpTime_t. It wasn't really needed,
	* generic/tclInt.h:      but caused warnings related to
	* generic/tclInt.decls:  strict aliasing with GCC 3.3.
	* generic/tclClock.c:

	lsearch (with the right options, set element removal can be done)
	following discussion on tkchat.

2004-03-16  Don Porter  <dgp@users.sourceforge.net>

	* doc/catch.n:	Compiled [catch] no longer fails to catch syntax
	errors.  Removed the claims in the documentation that it does.
	* doc/return.n:	Updated example to use [dict merge].

2004-03-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/configure, unix/tcl.m4: add -Wno-strict-aliasing for GCC to
	suppress useless type puning warnings.

2004-03-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/file.n: *roff formatting fix. [Bug 917171]

2004-03-15  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinNotify.c: Fixed a mistake where the return value of
	MsgWaitForMultipleObjectsEx for "a message is in the queue" wasn't
	accurate.  I removed the check on the case result==(WAIT_OBJECT_0 + 1)
	This was having the error of falling into GetMessage and waiting
	there by accident, which wasn't alertable through Tcl_AlertNotifier.
	I'll do some more study on this and try to find-out why.

2004-03-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	IMPLEMENTATION OF TIP#163
	* generic/tclDictObj.c (DictMergeCmd):	This is based on work by Joe
	* tests/dict.test (dict-20.*):		English in Tcl [FRQ 745851]
	* doc/dict.n:				but not exactly.

2004-03-10  Kevin B. Kenny <kennykb@acm.org>

	* generic/tclGetDate.y (TclGetDate): Fix so that 
	[clock scan <timeOfDay> -gmt true] uses the GMT base date
	instead of the local one. [Bug 913513]
	* tests/clock.test: Added test cases for wrong ISO8601 week number
	[Bug 500285] and wrong GMT base date [Bug 913513].  Several tests
	still fail on Windows, and these are actual faults in [clock scan].
	Fix is still pending.
	* generic/tclDate.c: Regenerated.

2004-03-08  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c:  Fix to 'glob -path' near the root
	* tests/fileName.test:    of the filesystem. [Bug 910525]

2004-03-08  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclParse.c (TclParseInit):	Modified TclParseInit so
	* generic/tclTest.c ([testexprparser]): that Tcl_Parse initialization
	conforms to documented promised about what fields will not be
	modified by what Tcl_Parse* routines. [Bug 910595]

2004-03-05  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/configure.in: Check for define of
	MWMO_ALERTABLE in winuser.h.
	* win/tclWinPort.h: If MWMO_ALERTABLE
	is not defined in winuser.h then define it.
	This is needed for Mingw.

2004-03-05  Kevin B. Kenny <kennykb@acm.org>

	* generic/tclTest.c: Modified TesteventObjCmd to use
	a Tcl_QueuePosition in place of an 'int' for the enumerated
	queue position, to avoid a compiler warning on SGI.
	(Bug #771960).

2004-03-05  Kevin B. Kenny <kennykb@acm.org>

	* tests/registry.test: Applied fix from Patch #910174 to
	make the test for an English-language system include any
	country code, rather than just English-United States.1252.
	Thanks to Pat Thoyts for the changes.

2004-03-04  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* tests/registry.test: Applied fixed from #766159 to skip two
	tests on Win98 that depend on a Unicode registry (NT specific).

2004-03-04  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.h (TclParseInit):	Factored the common code
	* generic/tclParse.c (TclParseInit):	for initializing a Tcl_Parse
	* generic/tclParseExpr.c:		struct into one routine.

2004-03-04  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* library/reg/pkgIndex.tcl:  Added TIP #100 support to the
	* win/tclWinReg.c:           registry package (patch #903831)
	This provides a Windows test of the TIP #100 mechanism and 
	a sample to show how unloading an extension can be done.

2004-03-04  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/dltest/pkgua.c: Fix minor syntax problems. [Bug 909288]

2004-03-03  Jeff Hobbs  <jeffh@ActiveState.com>

	*** 8.5a1 TAGGED FOR RELEASE ***

	* changes: updated for 8.5a1

2004-03-03  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc: default environment variable for VC++ is
	%MSDevDir% not %MSVCDir%, although vcvars32.bat sets both.

	* win/tclWinNotify.c (Tcl_WaitForEvent) : Allows an idling
	notifier to service "Asynchronous Procedure Calls" from its wait
	state.  Only useful for extension authors who decide they might
	want to try "completion routines" with WriteFileEx(), as an
	example.  From experience, I recommend that "completion	ports"
	should be used instead as the execution of the callbacks are more
	managable.

2004-03-01  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tcl.m4 (SC_CONFIG_CFLAGS):	Allow 64-bit enabling on
	IRIX64-6.5* systems.  [Bug 218561]
	* unix/configure:	autoconf-2.57

	* generic/tclTrace.c (TclCheckInterpTraces):	The TIP 62
	* generic/tclTest.c (TestcmdtraceCmd):	implementation introduced a
	* tests/trace.test (trace-29.10):	bug by testing the CallFrame
	level instead of the iPtr->numLevels level when deciding what traces
	created by Tcl_Create(Obj)Trace to call.  Added test to expose the
	error, and made fix. [Request 462580]

2004-02-28  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/fileSystem.test: fix to Tcl Bug 905163.

	* macosx/Makefile: fixed copyright year in Tcl.framework Info.plist

2004-02-25  Don Porter	<dgp@users.sourceforge.net>

	* tests/basic.test:	Made several tests more robust to the
	* tests/cmdMZ.test:	list-quoting of path names that might
	* tests/exec.test:	contain Tcl-special chars like { or [.
	* tests/io.test:	Should help us sort out Tcl Bug 554068.
	* tests/pid.test:

2004-02-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclLoad.c (Tcl_LoadObjCmd): Missing dereference caused
	segfault with non-loadable extension. [Bug 904307]

	* unix/tclUnixChan.c (TcpGetOptionProc): Stop memory leak with
	very long hostnames.  [Bug 888777]

2004-02-25  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/tclWinDde.c: Removed some gcc warnings - except for the 
	-Wconversion warning for GetGlobalAtomName. gcc is just wrong
	about this.

2004-02-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	IMPLEMENTATION OF TIP#100 FROM GEORGIOS PETASIS
	* generic/tclLoad.c (Tcl_UnloadObjCmd): Implementation.
	* tests/unload.test:			Test suite.
	* unix/dltest/pkgua.c:			Helper for test suite.
	* doc/unload.n:				Documentation.
	Also assorted changes (mostly small) to several other files.

2004-02-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/regc_locale.c (cclass): Buffer was having its size reset
	instead of being released => memleak. [Bug 902562]

2004-02-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclLoad.c (Tcl_LoadObjCmd): Fixed memory leak due to
	an improper error exit route.

2004-02-20  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinSock.c (SocketThreadExitHandler): Don't call
	TerminateThread when WaitForSingleObject returns a timeout.
	Tcl_Finalize called from DllMain will pause all threads.  Trust
	that the thread will get the close notice at a later time if it
	does ever wake up before being cleaned up by the system anyway.

2004-02-17  Don Porter	<dgp@users.sourceforge.net>

	* doc/tcltest.n:
	* library/tcltest/tcltest.tcl:	Changed -verbose default value to
	{body error} so that detailed information on unexpected errors in
	tests is provided by default, even after the fix for [Bug 725253]

2004-02-17  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/unixInit.test (unixInit-7.1):
	* unix/tclUnixInit.c (TclpInitPlatform): ensure the std fds exist
	to prevent crash condition [Bug #772288]

2004-02-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Bozo mistake in
	memory releasing order when in an error case.  [Bug 898910]

2004-02-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclTrace.c (TclTraceExecutionObjCmd) 
	(TclTraceCommandObjCmd): fix possible mem leak in trace info.

2004-02-12  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWinInit.c (AppendEnvironment):
	Use the tail component of the passed in
	lib path instead of just blindly using
	lib+4. That worked when lib was "lib/..."
	but fails for other values. Thanks go to
	Patrick Samson for pointing this out.

2004-02-10  David Gravereaux  <davygrvy@pobox.com>

	* win/nmakehlp.c: better macro grepping logic.

2004-02-07  David Gravereaux  <davygrvy@pobox.com>

	* win/makefile.vc:
	* win/rules.vc:
	* win/tcl.rc:
	* win/tclsh.rc:  Added an 'unchecked' option to the OPTS macro so a
	core built with symbols can be linked to the non-debug enabled C
	run-time.  As per discussion with Kevin Kenny.  Called like this:

		nmake -af makefile.vc OPTS=unchecked,symbols

	This clarifies the meaning of the 'g' naming suffix to mean only that
	the binary requires the debug enabled C run-time.  Whether the binary
	contains symbols or not is a different condition.

2004-02-06  Don Porter	<dgp@users.sourceforge.net>

	* doc/clock.n:	Removed reference to non-existent [file ctime].

2004-02-05  David Gravereaux  <davygrvy@pobox.com>

	* docs/tclvars.n: Added clarification of the tcl_platform(debug)
	var that it only refers to the flavor of the C run-time, and not
	whether the core contains symbols.

2004-02-05  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclFileName.c (SkipToChar):	Corrected CONST and
	type-casting issues that caused compiler warnings.

2004-02-04  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCmdAH.c (StoreStatData):	Removed improper refcount
	decrement of the varName parameter.  This error was causing
	segfaults following test cmdAH-28.7.

	* library/tcltest/tcltest.tcl:	Corrected references to
	non-existent $name variable in [cleanupTests]. [Bug 833637]

2004-02-03  Don Porter	<dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:	Corrected parsing of single
	command line argument (option with missing value) [Bug 833910]
	* library/tcltest/pkgIndex.tcl:	Bump to version 2.2.5.

2004-02-02  David Gravereaux <davygrvy@pobox.com>

	* generic/tclIO.c (Tcl_Ungets): Fixes improper filling of the
	channel buffer. This is the buffer before the splice. [Bug 405995]

2004-02-01  David Gravereaux <davygrvy@pobox.com>

	* tests/winPipe.test: more pass-thru commandline verifications.
	* win/tclWinPipe.c (BuildCommandLine): Special case quoting for
	'{' not required by the c-runtimes's parse_cmdline().
	* win/tclAppInit.c: Removed our custom setargv() in favor of
	the work provided by the c-runtime. [Bug 672938]

	* win/nmakehlp.c: defensive techniques to avoid static buffer
	overflows and a couple envars upsetting invokations of cl.exe
	and link.exe.  [Bug 885537]

	--------
	* tests/winPipe.test: Added proof that BuildCommandLine() is not
	doing the "N backslashes followed a quote -> insert N * 2 + 1
	backslashes then a quote" rule needed for the crt's
	parse_cmdline().
	* win/tclWinPipe.c: Fixed BuildCommandLine() to pass the new
	cases.

2004-01-30  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc: Use the -GZ compiler switch when building for
	symbols.  This is supposed to emulate the release build better to
	avoid hiding problems that only show themselves in a release
	build.

2004-01-29  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: fix to [Bug 883143] in file normalization

2004-01-29  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/file.n: 
	* generic/tclFCmd.c
	* generic/tclTest.c
	* library/init.tcl
	* mac/tclMacFile.c
	* tests/fileSystem.test: fix to [Bug 886352] where 'file copy
	-force' had inconsistent behaviour wrt target files with
	insufficient permissions, particular from vfs->native fs.
	Behaviour of '-force' is now always consistent (and now
	consistent with behaviour of 'file delete -force').  Added new
	tests and documentation and cleaned up the 'simplefs' test
	filesystem.

	* generic/tclIOUtil.c
	* unix/tclUnixFCmd.c
	* unix/tclUnixFile.c
	* win/tclWinFile.c: made native filesystems more robust to C code
	which asks for mount lists.

	* generic/tclPathObj.c: fix to [Bug 886607] removing warning/error
	with some compilers.

2004-01-28  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclObj.c (SetBooleanFromAny): Rewrite to do more
	efficient string->bool conversion.
	Many other minor whitespace/style fixes to this file too.

2004-01-27  David Gravereaux <davygrvy@pobox.com>

	* win/nmakehlp.c: Use '.\nul' as the sourcefile name instead of
	'nul' so VC 5.2 doesn't try searching the path for it and failing
	with a possible dialogbox popping up about having to add a CD to
	an empty drive.  Also added a SetErrorMode() call to disable any
	dialogs that cl.exe or link.exe might create.  [Bug 885537]

2004-01-22  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/file.n: clarified documentation of 'file system' [Bug 883825]
	* tests/fCmd.test: improved test result in failure case.

2004-01-22  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/fileSystem.test: 3 new tests
	* generic/tclPathObj.c: fix to [Bug 879555] in file normalization. 
	* doc/filename.n: small clarification to Windows behaviour with
	filenames like '.....', 'a.....', '.....a'.

	* generic/tclIOUtil.c: slight improvement to native cwd caching
	on Windows.

2004-01-21  David Gravereaux <davygrvy@pobox.com>

	* doc/Panic.3:  Mentions of 'panic' and 'panicVA' removed from
	the documentation.

2004-01-21  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/FileSystem.3: 
	* generic/tcl.decls: 
	* generic/tclCmdAH.c
	* generic/tclDecls.h
	* generic/tclFCmd.c
	* generic/tclFileName.c
	* generic/tclFileSystem.h
	* generic/tclIOUtil.c
	* generic/tclInt.decls
	* generic/tclInt.h
	* generic/tclIntDecls.h
	* generic/tclPathObj.c
	* generic/tclStubInit.c
	* generic/tclTest.c
	* mac/tclMacFile.c
	* tests/fileName.test
	* tests/fileSystem.test
	* tests/winFCmd.test
	* unix/tclUnixFile.c
	* win/tclWin32Dll.c
	* win/tclWinFCmd.c
	* win/tclWinFile.c
	* win/tclWinInt.h

	Three main issues accomplished: (1) cleaned up variable names in
	the filesystem code so that 'pathPtr' is used throughout.  (2)
	applied a round of filesystem optimisation with better handling
	and caching of relative and absolute paths, requiring fewer
	conversions.  (3) clarifications to the documentation,
	particularly regarding the acceptable refCounts of objects.
	Some new tests added.  Tcl benchmarks show a significant
	improvement over 8.4.5, and on Windows typically a small
	improvement over 8.3.5 (Unix still appears to require
	optimisation).  TCL_FILESYSTEM_VERSION_2 introduced, but for
	internal use only.  There should be no public incompatibilities
	from these changes.  Thanks to dgp for extensive testing.

2004-01-19  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinPipe.c (Tcl_WaitPid): Fixed a thread-safety problem
	with the process list.  The delayed cut operation after the wait
	was going stale by being outside the list lock.  It now cuts
	within the lock and does a locked splice for when it needs to
	instead.  [Bug 859820]

2004-01-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompile.c, generic/tclCompile.h: Two new opcodes,
	INST_LIST_INDEX_IMM and INST_LIST_RANGE_IMM, that have operand(s)
	of new type OPERAND_IDX4 which represents indexes into things like
	lists (and perhaps other things eventually.)
	* generic/tclExecute.c (TclExecuteByteCode): Implementation of the
	new opcodes.  INST_LIST_INDEX_IMM does a simple [lindex] with
	either front- or end-based simple indexing.  INST_LIST_RANGE_IMM
	does an [lrange] with front- or end-based simple indexing for both
	the reference to the first and last items in the range.
	* generic/tclCompCmds.c (TclCompileLassignCmd): Generate bytecode
	for the [lassign] command.

2004-01-17  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinInit.c:  added #pragma comment(lib, "advapi32.lib")
	when compiling under VC++ so we don't need to specify it
	when linking.

2004-01-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCmdIL.c (Tcl_LassignObjCmd): Add more shimmering
	protection for when the list is also one of the variables.

	BASIC IMPLEMENTATION OF TIP#57
	* generic/tclCmdIL.c (Tcl_LassignObjCmd): Implementation of the
	[lassign] command that takes full advantage of Tcl's object API.
	* doc/lassign.n: New file documenting the command.
	* tests/cmdIL.test (cmdIL-6.*): Test suite for the command.

2004-01-15  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinReg.c:  Placed the requirement for advapi.lib into
	the object file itself with #paragma comment (lib, ...) when
	built with VC++.  This will simplify linking for users of the
	static library.

	* win/rules.vc:  Added new 'fullwarn' to the CHECKS commandline
	macro; sets $(FULLWARNINGS).

	* win/makefile.vc:  Removed 'advapi.lib' from $(baselibs).
	Added new logic to crank-up the warning levels for both compile
	and link when $(FULLWARNINGS) is set.  Some clean-up with how
	the resource files are built and how -DTCL_USE_STATIC_PACKAGES
	is sent when compiling the shells.

	* win/tclAppInit.c: Small change in how TCL_USE_STATIC_PACKAGES
	is used.

	* win/tcl.rc:
	* win/tclsh.rc: Some clean-up with how the resource files are
	built.  Fixed 'OriginalFilename' problem that still thought
	a debug suffix was still 'd', now is 'g'.

2004-01-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclDictObj.c (TraceDictPath, DictExistsCmd): Adjusted
	behaviour of [dict exists] so a failure to look up a dictionary
	along the path of dicts doesn't trigger an error.  This is how it
	was documented to behave previously...  [Bug 871387]

	* generic/tclDictObj.c: Assorted dict fixes from Peter Spjuth
	relating to [Bug 876170].
	(SetDictFromAny): Make sure that lists retain their ordering even
	when converted to dictionaries and back.
	(TraceDictPath): Correct object reference count handling!
	(DictReplaceCmd, DictRemoveCmd): Stop object leak.
	(DictIncrCmd,DictLappendCmd,DictAppendCmd,DictSetCmd,DictUnsetCmd): 
	Simpler handling of reference counts when assigning to variables.
	* tests/dict.test (dict-19.2): Memory leak stress test

2004-01-13  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd):  Silence compiler warnings.

	Patch 876451: restores performance of [return].  Also allows forms
	such as [return -code error $msg] to be bytecompiled.

	* generic/tclInt.h:	Factored Tcl_ReturnObjCmd() into two pieces:
	* generic/tclCmdMZ.c:	TclMergeReturnOptions(), which can parse the
	options to [return], check their validity, and create the
	corresponding return options dictionary, and TclProcessReturn(),
	which takes that return options dictionary and performs the
	[return] operation.

	* generic/tclCompCmds.c:	Rewrote TclCompileReturnCmd() to
	call TclMergeReturnOptions() at compile time so the return options
	dictionary is computed at compile time (when it is fully known).
	The dictionary is pushed on the stack along with the result, and
	the code and level values are included in the bytecode as operands.
	Also supports optimized compilation of un-[catch]ed [return]s from
	procs with default options into the INST_DONE instruction.

	* generic/tclExecute.c:	Rewrote INST_RETURN instruction to retrieve
	the code and level operands, pop the return options from the stack,
	and call TclProcessReturn() to perform the [return] operation.

	* generic/tclCompile.h:	New utilities include TclEmitInt4 macro
	* generic/tclCompile.c:	and TclWordKnownAtCompileTime().

	End Patch 876451.

	* generic/tclFileName.c (Tcl_GlobObjCmd):  Latest changes to
	management of the interp result by Tcl_GetIndexFromObj() exposed
	improper interp result management in the [glob] command procedure.
	Corrected by adopting the Tcl_SetObjResult(Tcl_NewStringObj) pattern.
	This stopped a segfault in test filename-11.36. [Bug 877677]

2004-01-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct, Tcl_WrongNumArgs):
	Create fresh objects instead of using the one currently in the
	interpreter, which isn't guaranteed to be fresh and unshared. The
	cost for the core will be minimal because of the object cache, and
	this fixes [Bug 875395].

2004-01-12  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompExpr.c (CompileLandOrLorExpr): cosmetic changes. 

2004-01-12  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompExpr.c (CompileLandOrLorExpr): new logic, fewer
	instructions. As a side effect, the instructions INST_LOR and
	INST_LAND are now never used.
	* generic/tclExecute.c (INST_JUMP*): small optimisation; fix a
	bug in debug code.

2004-01-11  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinThrd.c (Tcl_ConditionNotify): condPtr must be
	dereferenced to see if there are waiters else uninitialized
	datum is manipulated.  [Bug 849007 789338 745068]

2004-01-09  David Gravereaux <davygrvy@pobox.com>

	* generic/tcl.h: Renamed and deprecated #defines moved to within
	the #ifndef TCL_NO_DEPRECATED block.  This allows us to build Tcl
	to check for deprecated functions in use, such as panic() and
	Tcl_Ckalloc().  By request from DKF.  Extensions that build
	with -DTCL_NO_DEPRECATED now have these macros as restricted.
	***POTENTIAL INCOMPATIBILITY***

	* win/makefile.vc:
	* win/rules.vc:  Added -DTCL_NO_DEPRECATED usage to makefile.vc.
	Called like this:   nmake -af makefile.vc CHECKS=nodep

2004-01-09  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: fix to infinite loop in 
	TclFinalizeFilesystem [Bug 873311]
