path: root/ChangeLog

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].
	
	* doc/clock.n
	* generic/tclBasic.c (Tcl_CreateInterp, Tcl_HideUnsafeCommands):
	* generic/tclClock.c (all):
	* generic/tclInt.h:
	* generic/tclInterp.c (CreateSlave):
	* library/clock.tcl: (new file)
	* library/init.tcl (clock):
	* library/msgs/*.msg:(new files)
	* library/tzdata/*:
	* library/tzdata/*/*:
	* library/tzdata/*/*/*: (new files)
	* tools/installData.tcl: (new file)
	* tools/loadICU.tcl: (new file)
	* tools/makeTestCases.tcl: (new file)
	* tools/tclZIC.tcl: (new file)
	* unix/Makefile.in:
	* unix/configure: (regenerated)
	* unix/tcl.m4:
	* tests/clock.test (all):
	* win/Makefile.in:
	* win/Makefile.vc:
		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.

	*** POTENTIAL INCOMPATIBILITY ***

2004-08-16  Miguel Sofer <msofer@users.sf.net>

	* doc/SetVar.3:
	* generic/tclTest.c (TestseterrorcodeCmd):
	* generic/tclVar.c (TclPtrSetVar):
	* tests/result.test (result-4.*, result-5.*): [Bug 1008314]
	detected and fixed by dgp.

2004-08-13  Don Porter  <dgp@users.sourceforge.net>

	* library/msgcat/msgcat.tcl:	Added checks to prevent [mclocale]
	* tests/msgcat.test:	from registering filesystem paths to possibly
	malicious code to be evaluated by a later [mcload].

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

        * unix/tclUnixThrd.c (TclpThreadCreate): changed handling of
        the returned thread ID since broken on 64-bit systems (Cray).
        Thanks to Rob Ratcliff for reporting the bug.

2004-08-03  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclNamesp.c (MakeCachedEnsembleCommand): Initialize the
	epoch field cached in the subcommand. [Bug 989298]
	(NsEnsembleImplementationCmd): Plug a leak (thanks to Miguel Sofer
	for spotting it with valgrind) and reduce the number of goto
	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
	internal reps that could lead to accessing of freed memory.
	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

	* 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:

	* doc/lsearch.n: Improved examples on the advanced capabilities of
	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>

	* README:           update patchlevel to 8.5a1

2004-03-01  Don Porter  <dgp@users.sourceforge.net>

	* 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.
	* tests/fileName.test: fix to Tcl Bug 904705.

	* doc/{various}.n: removed 'the the' typos.

2004-02-26  Daniel Steffen  <das@users.sourceforge.net>

	* 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]

2003-12-25  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWin32Dll.c (DllMain): Add HAVE_NO_SEH
	blocks in place of __try and __except statements
	to support gcc builds. This is needed after
	David's changes on 2003-12-21. [Tcl patch 858493]

2003-12-23  David Gravereaux <davygrvy@pobox.com>

	* generic/tclAlloc.c:	All uses of 'panic' (the macro) changed
	* generic/tclBasic.c:	to 'Tcl_Panic' (the function).  The
	* generic/tclBinary.c:	#define of panic in tcl.h clearly states
	* generic/tclCkalloc.c:	it is deprecated in the comments.

2003-12-22  David Gravereaux <davygrvy@pobox.com>

	* win/nmakehlp.c:
	* win/rules.vc:  New feature for extensions that use rules.vc.
	Now reads header files for version strings.  No more hard coding
	TCL_VERSION = 8.5 and having to edit it when you swap cores.

	* win/makefile.vc: VERSION macro now set by reading tcl.h for it.

	* generic/tcl.h: Removed note that makefile.vc needs to have a
	version number changed.

2003-12-21  David Gravereaux <davygrvy@pobox.com>

	* win/tclWin32Dll.c: Structured Exception Handling added around
	Tcl_Finalize called from DllMain's DLL_PROCESS_DETACH.  We can't
	be 100% assured that Tcl is being unloaded by the OS in a stable
	condition and we need to protect the exit handlers should the
	stack be in a hosed state.  AT&T style assembly for SEH under
	MinGW has not been added yet.  This is a first part change for
	[Patch 858493]

2003-12-17  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclBinary.c (DeleteScanNumberCache): fixed crashing bug
	when numeric scan-value cache contains NULL value.

2003-12-17  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclCmdAH.c: 
	* unix/tclUnixFile.c: 
	* win/tclWinFCmd.c: 
	* tests/fCmd.test: 
	* tests/fileSystem.test: 
	* doc/file.n: final fix to support for relative links and
	its implications on normalization and other parts of the
	filesystem code.  Fixes [Bug 859251] and some Windows
	problems with recursive file delete/copy and symbolic links.

2003-12-17  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: 
	* tests/fileSystem.test: fix and tests for [Bug 860402] in new 
	file normalization code.

2003-12-17  Zoran Vasiljevic  <zv@archiware.com>

	* generic/tclIOUtil.c: fixed 2 memory (object) leaks.
	This fixes Tcl Bug #839519.

	* generic/tclPathObj.c: fixed Tcl_FSGetTranslatedPath
	to always return properly refcounted path object.
	This fixes Tcl Bug #861515.

2003-12-16  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/fCmd.test: marking fCmd-9.14.2, as nonPortable, since
	on Solaris one can change the name of the current directory
	with 'file rename'.
	* doc/FileSystem.3: clarified documentation on ownership
	of return objects/strings of some Tcl_FS* calls.

2003-12-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclThreadAlloc.c (binfo): Made variable file-local.

2003-12-15  David Gravereaux <davygrvy@pobox.com>

	* win/tcl.rc:
	* win/tclsh.rc: Slight modification to the STRINGIFY macro to
	support Borland's rc tool.

	* win/tclWinFile.c (TclpUtime) : utimbuf struct not a problem 
	with Borland.

	* win/tclWinTime.c (TclpGetDate) : Borland's localtime() has
	a slight behavioral difference.

	From Helmut Giese <hgiese@ratiosoft.com> [Patch 758097].

2003-12-14  David Gravereaux <davygrvy@pobox.com>

	* generic/tclInt.decls: commented-out entry for
	TclpCheckStackSpace, removing it from the Stubs table.  It's
	already declared in tclInt.h and labeled as a function that is
	not to be exported.  Regened tables.

2003-12-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): TIP#75 Implementation
	* tests/switch.test:	Can now get submatch information when
	* doc/switch.n:		using -regexp matching in [switch].

2003-12-14  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: complete rewrite of generic file 
	normalization code to cope with links followed by '..'.
	[Bug 849514], and parts of [859251]

2003-12-12  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinChan.c: Win32's SetFilePointer() takes LONGs not
	DWORDs (a signed/unsigned mismatch).  Redid local vars to
	avoid all casting except where truly required.

2003-12-12  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclCmdAH.c: fix to normalization of non-existent user
	name ('file normalize ~nobody') [Bug 858937]
	* doc/file.n: clarify behaviour of 'file link' when the target
	is not an absolute path.
	* doc/filename.n: correct documentation to say that Windows Tcl 
	does handle '~user', for recent Windows releases, and clarified
	distinction between MacOS 'classic' and MacOS X.
	* doc/glob.n: clarification of glob's behaviour when returning
	filenames starting with a '~'.

	* tests/fileSystem.test:
	* tests/fileName.test: new tests added for the normalization
	problem above and other recentlt reported issues.

	* win/tclWinFile.c: corrected unclear comments

	* unix/tclUnixFile.c: allow creation of relative links
	[Bug 833713]

2003-12-11  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinSock.c (SocketThreadExitHandler) : added a
	TerminateThread fallback just in case the socket handler thread
	is really in a paused state.  This can happen when Tcl is being
	unloaded by the OS from an exception handler.  See MSDN docs on
	DllMain, it states this behavior.

2003-12-09  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/configure:
	* unix/tcl.m4: updated OpenBSD build configuration based on
	[Patch #775246] (cassoff)

2003-12-09  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tclUnixPort.h:	#ifdef'd out declarations of errno which
	* tools/man2tcl.c:	are known to cause problems with recent
				glibc. [Bug 852369]

2003-12-09  Vince Darley  <vincentdarley@users.sourceforge.net>

	* win/tclWinFile.c: fix to NT file permissions code [Bug 855923]
	* tests/winFile.test: added tests for NT file permissions - patch
	and test scripts supplied by Benny.

	* tests/winFCmd.test: fixed one test for when not running in C:/

2003-12-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclBinary.c (DeleteScanNumberCache, ScanNumber): Made
	the numeric scan-value cache have proper references to the objects
	within it so strange patterns of writes won't cause references to
	freed objects. Thanks to Paul Obermeir for the report.  [Bug 851747]

2003-12-01  Miguel Sofer <msofer@users.sf.net>

	* doc/lset.n: fix typo [Bug 852224]

2003-11-24  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclParse.c:	Corrected faulty check for trailing white
	space in {expand} parsing.  Thanks Andreas Leitgeb.  [Bug 848262].
	* tests/parse.test: 	New tests for the bug.

2003-11-24  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: fix to [Bug 845778] - Infinite recursion 
	on [cd] (Windows only bug), for which new tests have just been 
	added.

2003-11-21  Don Porter	<dgp@users.sourceforge.net>

	* tests/winFCmd.test (winFCmd-16.10,11): Merged new tests from
	core-8-4-branch.

2003-11-20  Miguel Sofer <msofer@users.sf.net>

	* generic/tclVar.c: fix flag bit collision between
	LOOKUP_FOR_UPVAR and TCL_PARSE_PART1 (deprecated) [Bug 835020] 

2003-11-19  Don Porter	<dgp@users.sourceforge.net>

	* tests/compile.test (compile-16.22.0):	Improved test for the
	recent fix for Bug 845412.

2003-11-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompile.c (TclCompileScript): Added a guard for the
	expansion code so that long non-expanding commands don't get
	expansion infrastructure inserted in them, especially when that
	infrastructure isn't initialised.  [Bug 845412]

2003-11-18  David Gravereaux <davygrvy@pobox.com>

	* contrib/djgpp/Makefile:		Changes from Victor Wagner
	* contrib/djgpp/langinfo.c (new):	<vitus@45.free.net> for better
	* contrib/djgpp/langinfo.h (new):	DJGPP support.
	* unix/tclUnixInit.c:			.
	* unix/tclUnixChan.c:			.
	* unix/tclUnixFCmd.c:			.

2003-11-17  Don Porter	<dgp@users.sourceforge.net>

	* tests/reg.test: Added tests for [Bugs 230589, 504785, 505048, 840258]
	recently fixed by 2003-11-15 commit to regcomp.c by Pavel Goran.
	His notes on the fix: This bug results from an error in code that
	splits states into "progress" and "no-progress" ones. This error
	causes an interesting situation with the pre-collected single-linked
	list of states to be splitted: many items were added to the list, but 
	only several of them are accessible from the list beginning, 
	since the "tmp" member of struct state (which is used here to
	hold a pointer to the next list item) gets overwritten, which 
	results in a "looped" chain. As a result, not all of states are
	splitted, and one state is splitted two times, causing incorrect
	"no-progress" flag values.

2003-11-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): Make sure that
	Tcl_AsyncInvoke is called regularly when processing bytecodes.
	* generic/tclTest.c (AsyncThreadProc, TestasyncCmd): Extended
	testing harness to send an asynchronous marking without relying on
	UNIX signals.
	* tests/async.test (async-4.*): Tests to check that async events
	are handled by the bytecode core. [Bug 746722]

2003-11-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclTest.c (TestHashSystemHashCmd): Removed 'const'
	modifier from hash type structure; it should be const and the hash
	code assumes it behaves like const, but that's not how the API is
	defined. Like this, we are following in the same footsteps as
	Tcl_RegisterObjType() which has the same conditions on its
	argument. Stops VC++5.2 warning.  [Bug 842511]

2003-11-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclHash.c (Tcl_DeleteHashTable,Tcl_HashStats,RebuildTable): 
	* generic/tclTest.c (TestHashSystemHashCmd): TIP#138 implementation, 
	* tests/misc.test:	plus a new chunk of stuff to test the hash
				functions more thoroughly in the test
				suite. [Patch 731356, modified] 

	* doc/Tcl.n: Updated Tcl version number and changebars.

2003-11-14  Don Porter	<dgp@users.sourceforge.net>

	* doc/ParseCmd.3:	Implementation of TIP 157.  Adds recognition
	* doc/Tcl.n:		of the new leading {expand} syntax on words.
	* generic/tcl.h:	Parses such words as the new Tcl_Token type
	* generic/tclBasic.c:	TCL_TOKEN_EXPAND_WORD.  Updated Tcl_EvalEx
	* generic/tclCompile.c: and the bytecode compiler/execution engine
	* generic/tclCompile.h:	to recognize the new token type.  New opcodes
	* generic/tclExecute.c:	INST_LIST_VERIFY and INST_INVOKE_EXP and a new
	* generic/tclParse.c:	operand type OPERAND_ULIST1 are defined.  Docs
	* generic/tclTest.c:	and tests are included.
	* tests/basic.test:
	* tests/compile.test:
	* tests/parse.test:

	* library/auto.tcl:	Replaced several [eval]s used to perform
	* library/package.tcl:	argument expansion with the new syntax.
	* library/safe.tcl:	In the test files lindex.test and lset.test,
	* tests/cmdInfo.test:	replaced use of [eval] to force direct
	* tests/encoding.test:	string evaluation with use of [testevalex]
	* tests/execute.test:	which more directly and robustly serves the
	* tests/fCmd.test:	same purpose.

2003-11-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/cmdMZ.test (cmdMZ-1.4): change to nonPortable as more
	systems are using permissions caching, and this isn't really a Tcl
	controlled issue.

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

	* unix/configure:
	* unix/tcl.m4: improve AIX --enable-64bit handling
	remove -D__NO_STRING_INLINES -D__NO_MATH_INLINES from
	CFLAGS_OPTIMIZE on Linux.  Make default opt -O2 (was -O).

2003-11-11  David Gravereaux <davygrvy@pobox.com>

	* contrib/djgpp/Makefile:  Suggested changes from vitus@45.free.net
	(Victor Wagner)

	* unix/tclUnixPort.h:  added socklen_t typedef for DJGPP

2003-11-10  Don Porter	<dgp@users.sourceforge.net>

	* unix/tclUnixInit.c (TclpInitLibraryPath):
	* win/tclWinInit.c (TclpInitLibraryPath):	Fix for [Bug 832657]
	that should not run afoul of startup constraints.

	* library/dde/pkgIndex.tcl:	Added safeguards so that registry
	* library/reg/pkgIndex.tcl:	and dde packages are not offered
	* win/tclWinDde.c:	on non-Windows platforms.  Bumped to
	* win/tclWinReg.c:	registry 1.1.3 and dde 1.3.
	* win/Makefile.in:
	* win/configure.in:
	* win/makefile.bc:

	* win/configure:	autoconf (2.57)

2003-11-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/cmdIL.test: Stopped cmdIL-5.5 from stomping over the test
	command, and updated the tests to use some tcltest2 features in
	relation to cleanup. [Bug 838384]

2003-11-10  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclCmdAH.c:
	* tests/fCmd.test: fix to misleading error message in 'file link'
	[Bug 836208]

2003-11-07  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: fix to compiler warning/error with
	some compilers [Bug 835918]

2003-11-07  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Makefile: optimized builds define NDEBUG to turn off
	ThreadAlloc range checking.

2003-11-05  Don Porter	<dgp@users.sourceforge.net>

	* tests/unixInit.test (unixInit-2.10):  New test to expose [Bug 832657]
	failure of TclpInitLibraryPath() to properly handle .. in the path
	of the executable.

2003-11-04  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Makefile: added 'test' target.

2003-11-03  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c
	* generic/tclInt.h: added comments and re-arranged code to
	clarify distinction between Tcl_LoadHandle, ClientData for
	'load'ed code, and point out limitations of the design 
	introduced with Tcl 8.4.

	* unix/tclUnixFile.c: fix to memory leak

	* generic/tclCmdIL.c: removed warning on Windows.

2003-11-01  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdIL.c (Tcl_LrepeatObjCmd): Check for sensible list
	lengths and allow for soft failure of the memory subsystem in the
	[lconcat] command [Bug 829027].  Uses direct list creation to
	avoid extra copies when working near the limit of available
	memory.  Also reorganized to encourage optimizing compilers to
	optimize heavily.
	* generic/tclListObj.c (TclNewListObjDirect): New list constructor
	that does not copy the array of objects. Useful for creating
	potentially very large lists or where you are about to throw away
	the array argument which is being used in its entirety.

2003-10-28  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (NEXT_INST macros): replaced macro variable
	"result" by "resultHandling" to avoid confusion.

2003-10-23  Andreas Kupries  <andreask@activestate.com>

	* unix/tclUnixChan.c (Tcl_MakeFileChannel): Applied [Patch 813606]
	  fixing [Bug 813087]. Detection of sockets was off for Mac OS X
	  which implements pipes as local sockets. The new code ensures
	  that only IP sockets are detected as such.

	* win/tclWinSock.c (TcpWatchProc): Watch for FD_CLOSE too when
	  asked for writable events by the generic layer.
	  (SocketEventProc): Generate a writable event too when a close is
	  detected.

	  Together the changes fix [Bug 599468].

2003-10-23  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/resource.test:
	* mac/tclMacResource.c: fix to resource freeing problem in 'resource'
	command reported by Bernard Desgraupes.

	* doc/FileSystem.3: updated documentation for 'glob' fix on 2003-10-13
	below

2003-10-22  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdAH.c (Tcl_FileObjCmd): Changed FILE_ prefix to FCMD_
	to stop symbol/#def clashes on Cygwin/Mingw32 on NT. [Bug 822528]

2003-10-21   Daniel Steffen  <das@users.sourceforge.net>

	* tools/tcltk-man2html.tcl: fixed incorrect html generated for
	.IP/.TP lists, now use <DL><DT>...<DD>...<P><DT>...<DD>...</DL>
	instead of illegal  <DL><P><DT>...<DD>...<P><DT>...<DD>...</DL>.
	Added skipping of directives directly after .TP to avoid them
	being used as item descriptions, e.g. .TP\n.VS in clock.n.

2003-10-21  Andreas Kupries  <andreask@pliers.activestate.com>

	* win/tclWinPipe.c (BuildCommandLine): Applied the patch coming
	  with [Bug 805605] to the code, fixing the incorrect use of
	  ispace noted by Ronald Dauster <ronaldd@users.sourceforge.net>.

2003-10-20  Kevin B. Kenny  <kennykb@users.sourceforge.net>

	* doc/msgcat.n:
	* library/msgcat/msgcat.tcl (mclocale,mcload):
	* tools/tcl.wse.in:
	* unix/Makefile.in:     Implementation of TIP#156
	* win/makefile.bc:      adding a "root locale" to
	* win/Makefile.in:      the 'msgcat' package. Advanced
	* win/Makefile.vc:      msgcat version number to 1.4.

2003-10-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdIL.c (SortInfo,etc): Reorganized so that SortInfo
	carries an array of integer indices instead of a Tcl list.  This
	nips shimmering problems in the bud and simplifies SelectObjFromSublist
	at the cost of making setup slightly more complex. [Bug 823768]

2003-10-14  David Gravereaux <davygrvy@pobox.com>

	* win/tclAppInit.c (sigHandler): Punt gracefully if exitToken
	has already been destroyed.

2003-10-14  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclCmdMZ.c:
	* tests/regexp.test: fix to [Bug 823524] in regsub; added three
	new tests.

2003-10-14  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c (TclAppendObjToErrorInfo):	New internal routine
	that appends a Tcl_Obj to the errorInfo, saving the caller the trouble
	of extracting the string rep.

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

	* generic/tclInt.h:	Declarations for new internal routines.

	* generic/tclCmdMZ.c:	Updated callers to use the new routines.
	* generic/tclCompExpr.c:
	* generic/tclCompile.c:
	* generic/tclExecute.c:
	* generic/tclIOUtil.c:
	* generic/tclNamesp.c:
	* generic/tclObj.c:
	* generic/tclParseExpr.c:
	* generic/tclProc.c:
	* generic/tclStringObj.c:
	* mac/tclMacResource.c:

	* library/init.tcl:	Updated ::errorInfo cleanup in [unknown] to
	reflect slight modifications to Tcl_LogCommandInfo().  Corrects
	failing init-4.* tests.

2003-10-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	TIP#127 IMPLEMENTATION FROM JOE MICHAEL SCHLENKER

	* generic/tclCmdIL.c (SelectObjFromSublist): Element selection engine.
	* generic/tclCmdIL.c (Tcl_LsearchObjCmd, Tcl_LsortObjCmd): 
	* tests/lsearch.test:	Set up and use of element selection engine,
	* tests/cmdIL.test:	plus tests and documentation.
	* doc/lsearch.n:	Based on [Patch 693836]
	* doc/lsort.n: 

2003-10-13  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tcl.h: 
	* generic/tclFileName.c:
	* generic/tclIOUtil.c:
	* generic/tclPathObj.c:
	* generic/tclTest.c:
	* mac/tclMacFile.c:
	* tests/fileName.test: better tests for [Bug 813273]
	* unix/tclUnixFCmd.c:
	* unix/tclUnixFile.c:
	* win/tclWin32Dll.c:
	* win/tclWinFCmd.c:
	* win/tclWinFile.c:
	* win/tclFileInt.h: 

	Fixed [Bug 800106] in which 'glob' was incapable of merging the
	results of a directory listing (real or virtual) and any virtual
	filesystem mountpoints in that directory (the latter were
	ignored).  This meant boundaries between different filesystems
	were not seamless (e.g. 'glob */*' across a filesystem boundary
	was wrong).  Added new entry to Tcl_GlobTypeData in a totally
	backwards compatible way.  To allow listing of mounts, registered
	filesystems must support the 'TCL_GLOB_TYPE_MOUNT' flag.  If this
	is not supported (e.g. in tclvfs 1.2) then mounts will simply not
	be listed for that filesystem.

	Fixed [Bug 749876] 'file writable/readable/etc' (NativeAccess)
	using correct permission checking code for Windows NT/2000/XP
	where more complex user-based security/access priveleges are
	available, particularly on shared volumes.  The performance
	impact of this extra checking will need further investigation.
	Note: Win 95,98,ME have no support for this.

	Also made better use of normalized rather than translated paths 
	in the platform specific code.

2003-10-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixTest.c (TestalarmCmd): don't bother checking return
	value of alarm. [Bug #664755] (english)

2003-10-09  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/makefile.vc:  Applied patches for bug #801467 by Joe Mistachkin
	* win/tclAppInit.c: to fix incompatible TCL_MEM_DEBUG handling in
	* generic/tclObj.c: Win32 VC builds.

2003-10-08  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Save and restore the iPtr->flag bits that
	control the state of errorCode and errorInfo management when calling
	"leave" execution traces, so that all error information of the traced
	command is still available whether traced or not.  [Bug 760947]
	Thanks to Yahalom Emet.

2003-10-08  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclTest.c (TestNumUtfCharsCmd): Command to allow finer
	access to Tcl_NumUtfChars for testing.
	* generic/tclUtf.c (Tcl_NumUtfChars): Corrected string length
	determining when the length parameter is negative; the terminator
	is a zero byte, not (necessarily) a \u0000 character. [Bug 769812]

	* tests/cmdAH.test:
	* tests/exec.test:		Corrected temporary file management

	* tests/pid.test:		[Bugs 675605, 675655, 675659]
	* tests/socket.test:
	* tests/source.test:

	* tests/fCmd.test:	Run tests with the [temporaryDirectory] as
	the current directory, so that tests can depend on ability to write
	files.	[Bug 575837]

	* doc/OpenFileChnl.3:	Updated Tcl_Tell and Tcl_Seek documentation
	to reflect that they now return Tcl_WideInt (TIP 72) [Bug 787537]

	* tests/io.test:	Corrected several tests that failed when paths
	* tests/ioCmd.test:	included regexp-special chars. [Bug 775394]

2003-10-06  Jeff Hobbs	<jeffh@ActiveState.com>

	* win/configure:
	* win/tcl.m4: removed incorrect checks for existence of
	optimization.  TCL_CFG_OPTIMIZED is now defined whenever the user
	does not build with --enable-symbols.

2003-10-06  Don Porter	<dgp@users.sourceforge.net>

	* tests/regexp.test:		Matched [makeFile] with [removeFile].
	* tests/regexpComp.test:	[Bug 675652]

	* tests/fCmd.test (fCmd-8.2):	Test only that tilde-substitution
	happens, not for any particular result. [Bug 685991]

	* unix/tcl.m4 (SC_PATH_TCLCONFIG):	Corrected search path so
	that alpha and beta releases of Tcl are not favored. [Bug 608698]

	* tests/reg.test:	Corrected duplicate test names.
	* tests/resource.test:	[Bugs 710370, 710358]

2003-10-04  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (TEBC):
	* tests/execute.test (execute-8.2): fix for [Bug 816641] - faulty
	execution and catch stack management.

2003-10-03  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Fixed error in ref count management of command
	* generic/tclCmdMZ.c:	and execution traces that caused access to
	freed memory in trace-32.1.  [Bug 811483].

2003-10-02  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclTrace.c: Corrected comingling of introspection results of
	[trace info command] and [trace info execution].  [Bug 807243]
	Thanks to Mark Saye.

2003-10-01  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Makefile: fixed redo prebinding bug when DESTDIR="".
	* mac/tclMacResource.c: fixed possible NULL dereference (bdesgraupes).

2003-09-29  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c:
	* tests/fileName.test: fix to inconsistent handling of backslash
	path separators on Windows in 'file join' [Bug 813273]

2003-09-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclPathObj.c (TclNativePathInFilesystem,TclFSGetPathType): 
	* generic/tclIOUtil.c (TclNativeDupInternalRep,TclGetPathType): Rename
	to make sure function names won't interfere with other non-Tcl
	code (reported by George Staplin)

	TIP#121 IMPLEMENTATION FROM JOE MISTACHKIN

	* generic/tclEvent.c (Tcl_SetExitProc,Tcl_Exit): Implementation of
	application exit handler scheme.
	* generic/tcl.decls (Tcl_SetExitProc): Public declaration.
	* doc/Exit.3: Documentation of new API function.

	TIP#112 IMPLEMENTATION

	* generic/tclNamesp.c: Core of implementation.
	* generic/tclInt.h (Namespace,TclInvalidateNsCmdLookup): Add
	command list epoch counter and list of ensembles to namespace
	structure, and define a macro to ease update of the epoch
	counter.
	* generic/tclBasic.c (Tcl_CreateObjCommand,etc.): Update epoch
	counter when list of commands in a namespace changes.
	* generic/tclObj.c (TclInitObjSubsystem): Register ensemble
	subcommand type.
	* tests/namespace.test (42.1-47.6): Tests.
	* doc/namespace.n: Documentation.

	* library/http/http.tcl (geturl): Correctly check the type of
	boolean-valued options. [Bug 811170]

	* unix/tcl.m4 (SC_ENABLE_FRAMEWORK): Added note to make it clearer
	that this is an OSX feature, not a general Unix feature. [Bug 619440]

2003-09-28  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinPipe.c: The windows port of expect can call
	TclWinAddProcess before any of the other pipe functions.
	Added a missing PipeInit() call to make sure the
	initialization happens.

2003-09-25  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Makefile: ensure SYMROOT exists if OBJROOT is overridden 
	on command line. Replaced explict use of /usr/bin by ${BINDIR}.

2003-09-24  Vince Darley  <vincentdarley@users.sourceforge.net>

	* library/package.tcl (tcl::MacPkgUnknown, tcl::MacOSXPkgUnknown):  
	Minor performance tweaks to reduce the number of [file] invocations.  
	Meant to improve startup times, at least a little bit.  
	(The generic equivalent patch was applied on 2003-02-21).

2003-09-24  Vince Darley  <vincentdarley@users.sourceforge.net>

	* trace.test: removed 'knownBug' from a test which doesn't
	illustrate a bug, just a bad test.

2003-09-23  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c:
	* generic/tclInt.h: changed the evaluation-stack addressing mode,
	from array-style to pointer-style; the catch stack and evaluation
	stack are now contiguous in memory. [Patch 457449]

2003-09-23  Don Porter  <dgp@users.sourceforge.net>

	* tests/trace.test (trace-31,32-*):  Added tests for [Bug 807243]
	and [Bug 811483].

	* library/init.tcl (auto_load, auto_import):  Expanded Eric Melski's
	2000-01-28 fix for [Bug 218871] to all potentially troubled uses of
	[info commands] on input data, where glob-special characters could
	cause problems.

2003-09-20  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/expr.test (expr-23.4): Prevented accidental wrapping round
	of exponential operation; it isn't portable, and not what I
	intended to test either. [Bug 808244]

2003-09-19  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c: adding (DE)CACHE_STACK_INFO() pairs to
	protect all calls that may cause traces on ::errorInfo or
	::errorCode to corrupt the stack [Bug 804681]

2003-09-17  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tclPathObj.c: fix to test-suite problem introduced by the bug 
	fix below.  No problem in ordinary code, just test suite code
	which manually adjusts tclPlatform. [Bug 808247]

2003-09-16  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/filename.n: documentation of Windows-specific feature as
        discussed in [Bug 541989]
	* generic/tclPathObj.c: fix for normalization of volume-relative
        paths [Bug 767834]
        * tests/winFCmd.test: new tests for both of the above. 
	* tests/cmdAH.test: fix for AFS problem in test suite [Bug 748960]

2003-09-13  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	TIP#123 IMPLEMENTATION BASED ON WORK BY ARJEN MARKUS

	* generic/tclCompile.h (INST_EXPON):		Implementation of
	* generic/tclCompile.c (tclInstructionTable):	exponential operator.
	* generic/tclCompExpr.c (operatorTable): 
	* generic/tclParseExpr.c (ParseExponentialExpr, GetLexeme): 
	* generic/tclExecute.c (TclExecuteByteCode, ExponWide, ExponLong): 
	(IllegalExprOperandType): 
	* tests/expr.test: 
	* tests/compExpr-old.test: 
	* doc/expr.n: 

2003-09-10  Don Porter  <dgp@users.sourceforge.net>

	* library/opt/optparse.tcl:	Latest revisions caused [OptGuessType]
	to guess "int" instead of "string" for empty strings.  Missed the
	required "-strict" option to [string is].  Thanks to Revar Desmera.
	[Bug 803968]

2003-09-08  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinLoad.c (TclpDlopen): Changed the error message for
	ERROR_PROC_NOT_FOUND to be a bit more helpful in giving us clues.
	"can't find specified procedure" means a function in the import
	table, for implicit loading, couldn't be resolved and that's why
	the load failed.

2003-09-04  Don Porter  <dgp@users.sourceforge.net>

	* doc/Tcl_Main.3:
	* doc/FileSystem.3:				Implementation of
	* doc/source.n:					TIPs 137/151.  Adds
	* doc/tclsh.1:					a -encoding option to
	* generic/tcl.decls:				the [source] command
	* generic/tclCmdMZ.c (Tcl_SourceObjCmd):	and a new C routine,
	* generic/tclIOUtil.c (Tcl_FSEvalFileEx):	Tcl_FSEvalFileEx(),
	* generic/tclMain.c (Tcl_Main):			that provides C access
	* mac/tclMacResource.c (Tcl_MacSourceObjCmd):	to the same function.
	* tests/cmdMZ.test:				Also adds command line
	* tests/main.test:	option handling in Tcl_Main() so that tclsh
	* tests/source.test:	and other apps built on Tcl_Main() respect
	a -encoding command line option before a script filename.  Docs and
	tests updated as well.  [Patch 742683]
	This is a ***POTENTIAL INCOMPATIBILITY*** only for those C programs
	that embed Tcl, build on Tcl_Main(), and make use of Tcl_Main's former
	ability to pass a leading "-encoding" option to interactive shell
	operations.

	* generic/tclInt.decls:				Added internal stub
	* generic/tclMain.c (Tcl*StartupScript*):	table entries for
	two new functions Tcl_SetStartupScript() and Tcl_GetStartupScript()
	that set/get the path and encoding for the startup script to be
	evaluated by either Tcl_Main() or Tk_Main().  Given public names in
	anticipation of their exposure by a followup TIP.

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

2003-09-04  Don Porter  <dgp@users.sourceforge.net>

	* doc/SplitList.3:	Implementation of TIP 148.  Fixes [Bug 489537].
	* generic/tcl.h:	Updated Tcl_ConvertCountedElement() to quote
	* generic/tclUtil.c:	the leading "#" character of all list elements
	unless the TCL_DONT_QUOTE_HASH flag is passed in.

	* generic/tclDictObj.c:	Updated Tcl_ConvertCountedElement() callers
	* generic/tclListObj.c:	to pass in the TCL_DONT_QUOTE_HASH flags
	* generic/tclResult.c:	when appropriate.

2003-08-31  Don Porter  <dgp@users.sourceforge.net>

	* doc/return.n:	Updated [return] docs to cover new TIP 90 features.

	* doc/break.n:		Added SEE ALSO references to return.n
	* doc/continue.n:

2003-09-01  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/Namespace.3: Basic documentation for the TIP#139 functions.
	This will need improving, but the basic bits are there at least.

2003-08-31  Don Porter  <dgp@users.sourceforge.net>

	* doc/catch.n:	Updated [catch] docs to cover new TIP 90 features.

2003-08-29  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdAH.c:	Corrected bug in TIP 90 implementation 
	* tests/cmdMZ.test:	where the default -errorcode NONE value
	was not copied into the return options dictionary.  This correction
	modified one test result.

2003-08-27  David Gravereaux <davygrvy@pobox.com>

	* compat/strftime.c (_fmt): Removed syst array intializer that
	couldn't take variables within it under the watcom compiler:
	'Initializers must be constant'.  I believe Borland has this
	strictness as well.  VC++ must be non-standard about this.

	Changed Win32 platform #ifdef from 'WIN32' to '__WIN32__' as
	this is the correct one to use across the Tcl sources.  Even
	though we do force it in tcl.h, the true parent one is __WIN32__.

	Added missing CONST'ification usage to match prototype listed
	in tclInt.decls.

	* win/tclWinPort.h:  Added a block for OpenWatcom adjustments
	that fixes 1) the same issue Mo did for MinGW lack of missing LPFN_*
	typedefs in their WINE derived <winsock2.h> and 2) The need to be
	strict about how the char type needs to be signed by default.

	* win/tclWinSock.c:  Added OpenWatcom to the commentary about the
	#ifdef HAVE_NO_LPFN_DECLS block.

	* win/tclWinTime.c:  Changed use of '_timezone' to 'timezone' as
	this difference is already adjusted for in tclWinPort.h.  Removed
	unreferenced posixEpoch file-scope global.

	* win/tclWinFile.c (WinReadLinkDirectory): Fix for 'Initializers
	must be constant' with the driveSpec array using OpenWatcom.

2003-08-27  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclUtil.c:	Corrected [Bug 411825] and other bugs in
	TclNeedSpace() where non-breaking space (\u00A0) and backslash-escaped
	spaces were handled incorrectly.  
	* tests/util.test:	Added new tests util-8.[2-6].

2003-08-26  David Gravereaux <davygrvy@pobox.com>

	* generic/tcl.h: Added some support for the LCC-Win32 compiler.
	Unfortunetly, this compiler has a bug in its preprocessor and
	can't build Tcl even with this minor patch.  Also added some
	support for the OpenWatcom compiler.  A new win/makefile.wc to
	follow soon.

2003-08-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tools/genStubs.tcl (genStubs::makeDecl): A more subtle way of
	generating stubbed declarations allows us to have declarations of
	a function in multiple interfaces simultaneously.

	* generic/tcl.decls: Duplicated some namespace declarations from
	tclInt.decls here, as mandated by TIP #139.  This is OK since the
	declarations match and will end up using the declarations in the
	public code from now on because of #include ordering.  Keeping the
	old declarations in tclInt.decls; there's no need to gratuitously
	break compatability for those extensions which are already clients
	of the namespace code.

2003-08-23  Zoran Vasiljevic  <zoran@archiwrae.com>

	* generic/tclIOUtil.c: merged fixes for thread-unsafe
	handling of filesystem records [Bug #753315]. 
	This also fixed the Bug #788780
	* generic/tclPathObj.c: merged fixes for thread-unsafe
	handling of filesystem records [Bug #753315]. 

	* generic/tclFileSystem.h: merged fixes for thread-unsafe
	handling of filesystem records [Bug #753315].

2003-08-19  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/tclWinSerial.c (SerialErrorStr): Fixed a syntax error
	created in the previous code cleanup.

2003-08-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* win/tclWinSerial.c: Adjusted commenting and spacing usage to
	follow the principles of the Style Guide better.

2003-08-18  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/tcl.m4 (SC_ENABLE_SYMBOLS): Use test instead
	of -eq, which does not work. [Bug 781109]

2003-08-13  Chengye Mao <chengye.geo@yahoo.com>

	* win/tclWinPipe.c: fixed a bug in BuildCommandLine.
	This bug built a command line with a missing space between
	tclpipe.dll and the following arguments.  It caused error
	in Windows 98 when exec command.com (e.g. dir) [Bug 789040]

2003-08-11  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	TIP #136 IMPLEMENTATION from Simon Geard <simon.geard@ntlworld.com>
	* generic/tclCmdIL.c (Tcl_LrepeatObjCmd): Adapted version of Simon's
	* doc/lrepeat.n:			  patch, updated to the HEAD
	* tests/lrepeat.test:			  and matching the core style.
	* generic/tclBasic.c (buildIntCmds):	Splice into core.
	* generic/tclInt.h: 
	* doc/list.n:				Cross-reference.

2003-08-06  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinInit.c: recognize amd64 and ia32_on_win64 cpus.

2003-08-06  Don Porter  <dgp@users.sourceforge.net>

	* library/msgcat/msgcat.tcl:	Added escape so that non-Windows
	* library/msgcat/pkgIndex.tcl:	platforms do not try to use the
	registry package.  This can save a costly and pointless package
	search.  Bumped to 1.3.1. Thanks to Dave Bodenstab.  [Bug 781609].

2003-08-05  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (INST_INVOKE, INST_EVAL, INST_PUSH_RESULT):
	added a Tcl_ResetResult(interp) at each point where the interp's
	result is pushed onto the stack, to avoid keeping an extra
	reference that may cause costly Tcl_Obj duplication [Bug 781585]
	Detected by Franco Violi, analyzed by Peter Spjuth and Donal
	Fellows. 

2003-07-28  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/FileSystem.3:
	* doc/Translate.3: better documentation of Tcl_TranslateFileName
	and related functions [Bug 775220]

2003-07-24  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tcl.h: Revert change made on 2003-07-21
	since it made the sizeof(Tcl_Obj) different for
	regular vs mem debug builds.
	* generic/tclInt.h: Define TclDecrRefCount in terms
	of Tcl_DbDecrRefCount which removes one layer of
	inderection.
	* generic/tclObj.c (TclDbInitNewObj, Tcl_DbIncrRefCount,
	Tcl_DbDecrRefCount, Tcl_DbIsShared):
	Define ThreadSpecificData that contains a hashtable.
	The table is used to ensure that a Tcl_Obj is only
	acted upon in the thread that allocated it. This
	checking code is enabled only when mem debug and
	threads are enabled.

2003-07-24  Don Porter  <dgp@users.sourceforge.net>

	* tests/async.test:	Added several tests that demonstrate Tcl
	* tests/basic.test:	Bug 489537, Tcl's longstanding failure to
	* tests/dict.test:	properly quote any leading '#' character
	* tests/dstring.test:	when generating the string rep of a list
	* tests/list.test:	so that the comment-power of that character
	* tests/parse.test:	is hidden from any [eval], in order to 
	* tests/util.test:	satisfy the documentation that [list] does
	[eval]-safe quoting.

2003-07-24  Reinhard Max  <max@suse.de>

	* library/package.tcl: Fixed a typo that broke pkg_mkIndex -verbose.
	* tests/pkgMkIndex.test: Added a test for [pkg_mkIndex -verbose].

	* ChangeLog.2002 (new file):
	* ChangeLog: broke changes from 2002 into ChangeLog.2002 to reduce
	  size of the main ChangeLog.

2003-07-23  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in: changes to html-tcl & html-tk
	targets for compatibility with non-gnu makes.

	* unix/Makefile.in: added macosx/README to dist target.

2003-07-23  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/tclWinReg.c (OpenSubKey): Fixed bug 775976 which causes the
	registry set command to fail when built with VC7.
	* library/reg/pkgIndex.tcl: Incremented the version to 1.1.2.

2003-07-21  Mo DeJong  <mdejong@users.sourceforge.net>

	Check that the thread incrementing or decrementing
	the ref count of a Tcl_Obj is the thread that
	originally allocated the thread. This fail fast
	behavior will catch programming errors that
	allow a single Tcl_Obj to be accessed from multiple
	threads.

	* generic/tcl.h (Tcl_Obj): Add allocThread member
	to Tcl_Obj. This member records the thread id the
	Tcl_Obj was allocated. It is used to check that
	any future ref count incr or decr is done from
	the same thread that allocated the Tcl_Obj.
	This member is defined only when threads and
	mem debug are enabled.
	* generic/tclInt.h (TclNewObj, TclDbNewObj,
	TclDecrRefCount):
	Define TclNewObj and TclDbNewObj using TclDbInitNewObj
	when mem debug is enabled. This fixes a problem where
	TclNewObj calls did not work the same as TclDbNewObj
	when mem debug was enabled.
	* generic/tclObj.c (TclDbInitNewObj, Tcl_DbIncrRefCount,
	Tcl_DbDecrRefCount): Add new helper to init Tcl_Obj
	members when mem debug is enabled. Init the allocThread
	member in TclDbInitNewObj and check it in
	Tcl_DbIncrRefCount and Tcl_DbDecrRefCount to make sure
	a Tcl_Obj allocated in one thread is not being acted
	upon in another thread.

2003-07-21  Vince Darley  <vincentdarley@users.sourceforge.net>

	* test/cmdAH.test: ensure certain tests run in local filesystem
        [Bug 748960]

2003-07-18  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Makefile: added option to allow installing manpages
	in addition to default html help.

2003-07-18  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/Utf.3: Tightened up documentation of Tcl_UtfNext and
	Tcl_UtfPrev to better match the behaviour. [Bug 769895]

2003-07-18  Jeff Hobbs  <jeffh@ActiveState.com>

	* library/http/pkgIndex.tcl: upped to http v2.4.4
	* library/http/http.tcl: add support for user:pass info in URL.
	* tests/http.test:       [Bug 759888] (shiobara)

2003-07-18  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n:                Restored the [Eval] proc to replace
	* library/tcltest/tcltest.tcl:  the [::puts] command when either the
	-output or -error option for [test] is in use, in order to capture
	data written to the output or error channels for comparison against
	what is expected.  This is easier to document and agrees better with
	most user expectations than the previous attempt to replace [puts]
	only in the caller's namespace.  Documentation made more precise on
	the subject.  [Bug 706359]

	* doc/AddErrInfo.3:	Improved consistency of documentation
	* doc/CrtTrace.3:      	by using "null" everywhere to refer to
	* doc/Encoding.3:      	the character '\0', and using "NULL"
	* doc/Eval.3:          	everywhere to refer to the value of a
	* doc/GetIndex.3:      	pointer that points to nowhere.
	* doc/Hash.3:          	Also dropped references to ASCII that
	* doc/LinkVar.3:       	are no longer true, and standardized on
	* doc/Macintosh.3:     	the hyphenated spelling of "null-terminated".
	* doc/OpenFileChnl.3:   
	* doc/SetVar.3:         
	* doc/StringObj.3:      
	* doc/Utf.3:            

	* doc/CrtSlave.3 (Tcl_MakeSafe):  Removed warning about possible
	deprecation (no TIP on that).

2003-07-17  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixFCmd.c: fix for compilation errors on platforms where
	configure detects non-functional chflags(). [Bug 748946]

	* macosx/Makefile: Rewrote buildsystem for Mac OS X framework build
	to be purely make driven; in order to become independent of Apple's
	closed-source IDE and build tool. The changes are intended to be
	transparent to the Makefile user, all existing make targets and
	cmd line variable overrides should continue to work.
	Changed build to only include tcl specific html help in Tcl.framework,
	the tk specific html help is now included in Tk.framework.
	Added var to allow overriding of tclsh used during html help 
	building (Landon Fuller).

	* macosx/Tcl.pbproj/project.pbxproj:
	* macosx/Tcl.pbproj/jingham.pbxuser: Changed to purely call through
	to the make driven buildsystem; Tcl.framework is no longer assembled
	by ProjectBuilder.
	Set default SYMROOT in target options to simplify setting up PB
	(manually setting common build folder for tcl & tk no longer needed).

	* tools/tcltk-man2html.tcl: Added options to allow building only the
	tcl or tk html help files; the default behaviour with none of the new
	options is to build both, as before.

	* unix/Makefile.in: Added targets for building only the tcl or tk help.

	* macosx/README (new): Tcl specific excerpts of tk/macosx/README. 

	* generic/tcl.h: Updated reminder comment about editing
	macosx/Tcl.pbproj/project.pbxproj when version number changes.

2003-07-16  Mumit Khan  <khan@nanotech.wisc.edu>

	* generic/tclPathObj.c (SetFsPathFromAny): Add Cygwin specific
	code to convert POSIX filename to native format.
	* generic/tclFileName.c (Tcl_TranslateFileName): And remove from here.
	(TclDoGlob): Adjust for cygwin and append / for dirs instead of \
	* win/tclWinFile.c (TclpObjChdir): Use chdir on Cygwin.
	[Patch 679315]

2003-07-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* library/safe.tcl (FileInAccessPath): normalize paths before
	comparison. [Bug 759607] (myers)

	* unix/tclUnixNotfy.c (NotifierThreadProc): correct size of found
	and word vars from int to long. [Bug 767578] (hgo)

	* generic/tcl.h:       add recognition of -DTCL_UTF_MAX=6 on the
	* generic/regcustom.h: make line to support UCS-4 mode.  No config
	arg at this time, as it is not the recommended build mode.

	* generic/tclPreserve.c: In Result and Preserve'd routines, do not
	* generic/tclUtil.c:     assume that ckfree == free, as that is not
	* generic/tclResult.c:   always true. [Bug 756791] (fuller)

2003-07-16  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/CrtSlave.3 (Tcl_MakeSafe): Updated documentation to strongly
	discourage use.  IMHO code outside the core that uses this
	function is a bug...  [Bug 655300]

2003-07-16  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclFileName.c (Tcl_GlobObjCmd):	[Bug 771840]
	* generic/tclPathObj.c (Tcl_FSConvertToPathType):[Bug 771947]
	* unix/tclUnixFCmd.c (GetModeFromPermString):	[Bug 771949]
	Silence compiler warnings about unreached lines.

	* library/tcltest/tcltest.tcl (ProcessFlags):	Corrected broken call
	* library/tcltest/pkgIndex.tcl:			to [lrange].  Bumped
	to version 2.2.4. [Bug 772333]

2003-07-15  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/dltest/pkga.c (Pkga_EqObjCmd): Fix typo
	that was causing a crash in load.test.

2003-07-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/array.n: Make sure docs are synched with the 8.4 release.

2003-07-15  Don Porter  <dgp@users.sourceforge.net>

	* doc/http.n:  Updated SYNOPSIS to match actual syntax of
	commands.  [Bug 756112]

	* unix/dltest/pkga.c:	Updated to not use Tcl_UtfNcmp and counted
	strings instead of strcmp (not defined in any #include'd header)
	and presumed NULL-terminated strings.

	* generic/tclCompCmds.c (TclCompileIfCmd):  Prior fix of Bug 711371
	on 2003-04-07 introduced a buffer overflow.  Corrected.  [Bug 771613]

2003-07-15  Kevin B. Kenny  <kennykb@acm.org>

	* win/rules.vc: Added a missing $(OPTDEFINES) which broke the
	build if STATS=memdbg was specified.

2003-07-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdIL.c (SortCompare): Cleared up confusing error
	message. [Bug 771539]

2003-07-11  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/binary.test (binary-46.*): Tests to help enforce the
	current behaviour.
	* doc/binary.n: Documented that [binary format a] and [binary scan a]
	do encoding conversion by dropping high bytes, unlike the rest of
	the core. [Bug 735364]

2003-07-11  Don Porter  <dgp@users.sourceforge.net>

	* library/package.tcl:  Corrected [pkg_mkIndex] bug reported on
	comp.lang.tcl.  The indexer was searching for newly indexed packages
	instead of newly provided packages.

2003-07-08  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/winFCmd.test: fix for five tests under win98 [Bug 767679]

2003-07-07  Jeff Hobbs  <jeffh@ActiveState.com>

	* doc/array.n: add examples from Welton

2003-06-23  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/file.n: clarification of 'file tail' behaviour [Bug 737977]

2003-07-04  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/expr.n: Tighten up the wording of some operations. [Bug 758488]

	* tests/cmdAH.test: Made tests of [file mtime] work better on FAT
	filesystems. [Patch 760768]  Also a little general cleanup.

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Made [string map] accept
	dictionaries for maps.  This is much trickier than it looks, since
	map entry ordering is significant.  [Bug 759936]

	* generic/tclVar.c (Tcl_ArrayObjCmd, TclArraySet): Made [array
	get] and [array set] work with dictionaries, producing them and
	consuming them.  Note that for compatability reasons, you will
	never get a dict from feeding a string literal to [array set]
	since that alters the trace behaviour of "multi-key" sets.
	[Bug 759935]

2003-06-23  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclTrace.c: fix to Window debug build compilation error.

2003-06-27  Don Porter  <dgp@users.sourceforge.net>

	* tests/init.test: Added [cleanupTests] to report results of tests
	* tests/pkg.test:  that run in slave interps.  [Bugs 761334,761344]

	* tests/http.test: Used more reliable path to find httpd script.

2003-06-25  Don Porter  <dgp@users.sourceforge.net>

	* tests/init.test:  Added tests init-4.6.* to illustrate [Bug 760872]

2003-06-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclTrace.c: New file, factoring out of virtually all the
	various trace-related things from tclBasic.c and tclCmdMZ.c with
	the goal of making this a separate maintenance area.

2003-06-25  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Add -ieee when
	compiling with cc and add -mieee when compiling
	with gcc under OSF1-V5 "Tru64" systems.
	[Bug 748957]

2003-06-24  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/encoding.n: Corrected the docs to say that [source] uses the
	system encoding, which it always did anyway (since 8.1) [Bug 742100]

2003-06-24  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclHash.c (Tcl_HashStats): Prevented occurrence of
	division-by-zero problems.  [Bug 759749]

2003-06-24  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/tclUnixPort.h: #undef inet_ntoa before
	#define to avoid compiler warning under freebsd.
	[Bug 745844]

2003-06-23  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* doc/dde.n:                 Committed TIP #135 which changes the
	* win/tclWinDde.c:           -exact option to -force. Also cleaned
	* tests/winDde.test:         a bug in the tests.
	* library/dde/pkgIndex.tcl:  Incremented version to 1.2.5

	* doc/dde.n:                 Committed TIP #120 which provides the
	* win/tclWinDde.c:           dde package for safe interpreters.
	* tests/winDde.test:         Incremented package version to 1.2.4
	* library/dde/pkgIndex.tcl:

2003-06-23  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFCmd.c: fix to bad error message when trying to
	do 'file copy foo ""'. [Bug 756951]
	* tests/fCmd.test: added two new tests for the bug.

	* win/tclWinFile.c:
	* win/tclWin32Dll.c: recommitted some filesystem globbing 
	speed-ups, but disabled some on the older Win 95/98/ME where
	they don't seem to work.

	* doc/FileSystem.3: documentation fix [Bug 720634]

2003-06-18  Miguel Sofer <msofer@users.sf.net>

	* generic/tclNamesp.c (Tcl_Export): removed erroneous comments
	[Bug 756744]

2003-06-17  Vince Darley  <vincentdarley@users.sourceforge.net>

	* win/makefile.vc:  fixes to check-in below so compilation now
	works again on Windows.

	* generic/tclCmdMZ.c:
	* tests/regexp.test: fixing of bugs related to regexp and regsub
	matching of empty strings.  Addition of a number of new tests.
	[Bug 755335]

2003-06-16  Andreas Kupries  <andreask@activestate.com>

	* win/Makefile.in:  Haven't heard back from David for a week.
	* win/configure:    Now committing the remaining changes.
	* win/configure.in: Note: In active contact with Helmut Giese
	* win/makefile.vc:  about the borland relatedchanges. This part
	* win/rules.vc:     will see future updates.
	* win/tcl.m4:       
	* win/makefile.bc:

2003-06-10  Andreas Kupries  <andreask@activestate.com>

	* generic/tclConfig.c (ASSOC_KEY): Changed the key to
	  "tclPackageAboutDict" (tcl prefix) to make collisions with the
	  keys of other packages more unlikely.

2003-06-10  Miguel Sofer <msofer@users.sf.net>

	* generic/tclBasic.c:
	* generic/tclExecute.c: let TclExecuteObjvInternal call
	TclInterpReady instead of relying on its callers to do so; fix for
	the part of [Bug 495830] that is new in 8.4. 
	* tests/interp.test: Added tests 18.9 (knownbug) and 18.10

2003-06-09  Andreas Kupries  <andreask@activestate.com>

	* generic/tcl.decls:  Ported the changes from the
	* generic/tcl.h:      'tip-59-implementation' branch into the CVS
	* generic/tclBasic.c: head. Regenerated stub table. Regenerated
	* generic/tclInt.h:   the configure's scripts, with help from Joe
	* generic/tclDecls.h  English.
	* generic/tclStubInit.c:
	* generic/tclConfig.c:
	* generic/tclPkgConfig.c:
	* unix/Makefile.in:   
	* unix/configure.in:  The changes in the windows section are not
	* unix/tcl.m4:        yet committed, they await feedback from
	* unix/mkLinks:       David Gravereaux.
	* doc/RegConfig.3:
	* mac/tclMacPkgConfig.c:
	* tests/config.test:

2003-06-09  Don Porter  <dgp@users.sourceforge.net>

	* string.test (string-4.15): Added test for [string first] bug
	reported in Tcl 8.3, where test for all-single-byte-encoded strings
	was not reliable.

2003-06-04  Joe Mistachkin  <joe@mistachkin.com>

	* tools/man2help.tcl: Added duplicate help section checking
	* tools/index.tcl:    and corrected a comment typo for the 
	getTopics proc in index.tcl [Bug #748700].

2003-06-02  Vince Darley  <vincentdarley@users.sourceforge.net>

	* win/tclWinFCmd.c:
	* tests/fCmd.test: fix to [Bug #747575] in which a bad error
	message is given when trying to rename a busy directory to
	one with the same prefix, but not the same name.  Added three
	new tests.

2003-05-23  D. Richard Hipp <drh@hwaci.com>

	* win/tclWinTime.c: Add tests to detect and avoid a division by zero
	in the windows precision timer calibration logic.

2003-05-23  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclObj.c (tclCmdNameType):  Converted internal rep
	management of the cmdName Tcl_ObjType the opposite way, to always
	use the twoPtrValue instead of always using the otherValuePtr.
	Previous fix on 2003-05-12 broke several extensions that wanted
	to poke around with the twoPtrValue.ptr2 value of a cmdName
	Tcl_Obj, like TclBlend and e4graph.  [Bug 726018]
	Thanks to George Petasis for the bug report and Jacob Levy for
	testing assistance.

2003-05-23  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/mkLinks: Set the var S to "" at the top
	of the file to avoid error when user has set S
	to something.
	[Tk Bug #739833]

2003-05-22  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.pbproj/project.pbxproj: added missing references to
	new source files tclPathObj.c and tclMacOSXFCmd.c.

	* macosx/tclMacOSXBundle.c: fixed a problem that caused only the
	first call to Tcl_MacOSXOpenVersionedBundleResources() for a given
	bundle identifier to succeed. This caused the tcl runtime library
	not to be found in all interps created after the inital one.

2003-05-19  Kevin B. Kenny  <kennykb@hippolyta>

	* unix/tclUnixTime.c: Corrected a bug in conversion of non-ASCII
	chars in the format string.

2003-05-19  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.pbproj/project.pbxproj: changed tclConfig.sh location
	in versioned framework subdirectories to be identical to location
	in framework toplevel; fixed stub library symbolic links to be
	tcl version specific.

	* unix/tclUnixTime.c: fixed typo.

2003-05-18  Kevin Kenny  <kennykb@acm.org>

	* compat/strftime.c:  Modified TclpStrftime to return its
	* generic/tclClock.c: result in UTF-8 encoding, and removed
	* mac/tclMacTime.c:   the conversion from system encoding to
	* unix/tclUnixTime.c: UTF-8 from [clock format]. Needed to
	* win/tclWinTime.c:   avoid double conversion of the timezone
	                      name on Windows systems. [Bug 624408]

2003-05-16  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* library/dde/pkgIndex.tcl:  Applied TIP #130 which provides
	* tests/winDde.test:         for unique dde server names. Added
	* win/tclWinDde.c:           some more tests. Fixes [Bug 219293]

	* doc/dde.n: Updated documentation re TIP #130.
	* tests/winDde.test: Applied patch for [Bug 738929] by KKB and
	changed to new-style tests.

2003-05-16  Kevin B. Kenny  <kennykb@acm.org>

	* unix/Makefile.in:	Removed one excess source file tclDToA.c

2003-05-16  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.pbproj/project.pbxproj: updated copyright year.

2003-05-15  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclGetDate.y: added further hackery to the yacc
	* generic/tclDate.c:    post-processing to arrange for the
	* unix/Makefile.in:     code to set up exit handlers to free
	                        the stacks [Bug 736425].

2003-05-15  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinFile.c (TclpMatchInDirectory): revert glob code to
	r1.44 as 2003-04-11 optimizations broke Windows98 glob'ing.

	* doc/socket.n: nroff font handling correction

	* library/encoding/gb2312-raw.enc (new): This is the original
	gb2312.enc renamed to allow for it to still be used.  This is
	needed by Tk (unix) because X fonts with gb2312* charsets really
	do want the original gb2312 encoding. [Bug 557030]

2003-05-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Stop unwarranted demotion
	of wide values to longs by formatting of int values.  [Bug 699060]

2003-05-14  Jeff Hobbs  <jeffh@ActiveState.com>

	* library/encoding/gb2312.enc: copy euc-cn.enc over original
	gb2312.enc.  gb2312.enc appeared to not work as expected, and most
	uses of gb2312 really mean euc-cn (which may be the cause of the
	problem). [Bug 557030]

2003-05-14  Daniel Steffen  <das@users.sourceforge.net>

	Implementation of TIP 118:

	* generic/tclFCmd.c (TclFileAttrsCmd): return the list of attributes
	that can be retrieved without error for a given file, instead of
	aborting the whole command when any error occurs.

	* unix/tclUnixFCmd.c: added support for new file attributes and for
	copying Mac OS X file attributes & resource fork during [file copy].

	* generic/tclInt.decls: added declarations of new external commands
	needed by new file attributes support in tclUnixFCmd.c.

	* macosx/tclMacOSXFCmd.c (new): Mac OS X specific implementation of
	new file attributes and of attribute & resource fork copying.

	* mac/tclMacFCmd.c: added implementation of -rsrclength attribute &
	fixes to other attributes for consistency with OSX implementation.

	* mac/tclMacResource.c: fixes to OSType handling.

	* doc/file.n: documentation of [file attributes] changes.

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

	* unix/Makefile.in:
	* unix/tcl.m4: added new platform specifc tclMacOSXFCmd.c source.

	* unix/configure:
	* generic/tclStubInit.c:
	* generic/tclIntPlatDecls.h: regen.

	* tools/genStubs.tcl: fixes to completely broken code trying to
	prevent overlap of "aqua", "macosx", "x11" and "unix" stub entries.

	* tests/unixFCmd.test: added tests of -readonly attribute.

	* tests/macOSXFCmd.test (new): tests of macosx file attributes and
	of preservation of attributes & resource fork during [file copy].

	* tests/macFCmd.test: restore -readonly attribute of test dir, as
	otherwise its removal can fail on unices supporting -readonly.

2003-05-13  David Gravereaux <davygrvy@pobox.com>

	* generic/tclEnv.c: Another putenv() copy behavior problem
	repaired when compiling on windows and using microsoft's runtime.
	[Bug 736421]

2003-05-13  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclIOUtil.c: ensure cd is thread-safe.
	[Bug #710642] (vasiljevic)

2003-05-13  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclEvent.c (Tcl_Finalize): Removed unused variable to
	reduce compiler warnings.  [Bug 664745]

2003-05-13  Joe Mistachkin  <joe@mistachkin.com>

	* generic/tcl.decls:  Changed Tcl_JoinThread parameter name from
	* generic/tclDecls.h: "id" to "threadId". [Bug 732477]
	* unix/tclUnixThrd.c:
	* win/tclWinThrd.c: 
	* mac/tclMacThrd.c:

2003-05-13  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tcl.decls:
	* macosx/tclMacOSXBundle.c: added extended version of the 
	Tcl_MacOSXOpenBundleResources() API taking an extra version number
	argument: Tcl_MacOSXOpenVersionedBundleResources().
	This is needed to be able to access bundle resources in versioned
	frameworks such as Tcl and Tk, otherwise if multiple versions were
	installed, only the latest version's resources could be accessed.
	[Bug 736774]

	* unix/tclUnixInit.c (Tcl_MacOSXGetLibraryPath): use new versioned
	bundle resource API to get tcl runtime library for TCL_VERSION.
	[Bug 736774]

	* generic/tclPlatDecls.h:
	* generic/tclStubInit.c: regen.

	* unix/tclUnixPort.h: worked around the issue of realpath() not
	being thread-safe on Mac OS X by defining NO_REALPATH for threaded
	builds on Mac OS X. [Bug 711232]

2003-05-12  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/cmdAH.test: General clean-up of tests so that all
	tcltest-specific commands are protected by constraints and all
	platforms see the same number of tests.  [Bug 736431]

2003-05-12  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInterp.c: (AliasObjCmd):   Added refCounting of the words
	* tests/interp.test (interp-33.1):      of the target of an interp
	alias during its execution.  Also added test. [Bug 730244].

	* generic/tclBasic.c (TclInvokeObjectCommand):  objv[argc] is no
	longer set to NULL (Tcl_CreateObjCommand docs already say that it
	should not be accessed).

	* tests/cmdMZ.test:  Forgot to import [temporaryDirectory].

	* generic/tclObj.c (tclCmdNameType):  Corrected variable use of the
	otherValuePtr or the twoPtrValue.ptr1 fields to store a
	(ResolvedCmdName *) as the internal rep.  [Bug 726018].

	* doc/Eval.3:  Corrected prototype for Tcl_GlobalEvalObj [Bug 727622].

2003-05-12  Miguel Sofer <msofer@users.sf.net>

	* generic/tclVar.c (TclObjLookupVar): [Bug 735335] temporary fix,
	disabling usage of tclNsVarNameType.
	* tests/var.test (var-15.1): test for [Bug 735335]

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

	* win/tclWinSerial.c (SerialCloseProc): correct mem leak on
	closing a Windows serial port [Bug #718002] (schroedter)

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): prevent string repeat
	crash when overflow sizes were given (throws error). [Bug #714106]

2003-05-09  Joe Mistachkin <joe@mistachkin.com>

	* generic/tclThreadAlloc.c (TclFreeAllocCache): Fixed memory leak
	caused by treating cachePtr as a TLS index [Bug 731754].

	* win/tclAppInit.c (Tcl_AppInit): Fixed memory leaks caused by not
	freeing the memory allocated by setargv and the async handler created
	by Tcl_AppInit. An exit handler has been created that takes care of
	both leaks. In addition, Tcl_AppInit now uses ckalloc instead of
	Tcl_Alloc to allow for easier leak tracking and to be more consistent
	with the rest of the Tcl core [Bugs 733156, 733221].

	* tools/encoding/txt2enc.c (main): Fixed memory leak caused by failing
	to free the memory used by the toUnicode array of strings [Bug 733221].

2003-05-09  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c (TclCompileScript):
	* tests/compile.test (compile-3.5): corrected wrong test and
	behaviour in the earlier fix for [Bug 705406]; Don Porter reported
	this as [Bug 735055], and provided the solution.

2003-05-09  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdMZ.c (Tcl_ReturnObjCmd): The array of strings
	passed to Tcl_GetIndexFromObj must be NULL terminated.  [Bug 735186]
	Thanks to Joe Mistachkin for spotting this.

2003-05-07  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/trace.n: Fixed very strange language in the documentation
	for 'trace add execution'.  [Bug 729821]

	* generic/tclCmdMZ.c (Tcl_TraceObjCmd): Made error message for
	'trace info' more consistent with documentation.  [Bug 706961]

	* generic/tclDictObj.c (DictInfoCmd): Fixed memory leak caused by
	confusion about string ownership.  [Bug 731706]

2003-05-05  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:		Implementation of TIP 90, which
	* generic/tclCmdAH.c:		extends the [catch] and [return]
	* generic/tclCompCmds.c:	commands to enable creation of a
	* generic/tclExecute.c:		proc that is a replacement for
	* generic/tclInt.h:		[return]. [Patch 531640]
	* generic/tclProc.c:
	* generic/tclResult.c:
	* tests/cmdAH.test:
	* tests/cmdMZ.test:
	* tests/error.test:
	* tests/proc-old.test:

	* library/tcltest/tcltest.tcl: The -returnCodes option to [test]
	failed to recognize the symbolic name "ok" for return code 0.

2003-05-05  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclBasic.c (Tcl_HideCommand): Fixed error message for
	grammar and spelling.

2003-04-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclDictObj.c (DictIncrCmd): Updated to reflect the
	behaviour with wide increments of the normal [incr] command.
	* generic/tclInt.decls: Added TclIncrWideVar2 to internal stub
	table and cleaned up.
	* tests/incr.test (incr-3.*):
	* generic/tclVar.c (TclIncrWideVar2, TclPtrIncrWideVar): 
	* generic/tclExecute.c (TclExecuteByteCode): 
	* generic/tclCmdIL.c (Tcl_IncrObjCmd): Make [incr] work when
	trying to increment by wide values.  [Bug 728838]

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Default mode of
	operation of [switch] is exact matching.  [Bug 727563]

2003-04-25  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:  Tcl_EvalObjv() failed to honor the
	TCL_EVAL_GLOBAL flag when resolving command names.  Tcl_EvalEx
	passed a string rep including leading whitespace and comments
	to TclEvalObjvInternal().

2003-04-25  Andreas Kupries  <andreask@activestate.com>

	* win/tclWinThrd.c: Applied SF patch #727271. This patch changes
	  the code to catch any errors returned by the windows functions
	  handling TLS ASAP instead of waiting to get some mysterious
	  crash later on due to bogus pointers. Patch provided by Joe
	  Mistachkin.

	  This is a stop-gap measure to deal with the low number of ?TLS
	  slots provided by some of the variants of Windows (60-80).

2003-04-24  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c: fix to bug reported privately by
	Jeff where, for example, 'glob -path {[tcl]} *' gets confused
	by the leading special character (which is escaped internally),
	and instead lists files in '/'.  Bug only occurs on Windows 
	where '\' is also a directory separator.
	* tests/fileName.test: added test for the above bug.

2003-04-22  Andreas Kupries  <andreask@activestate.com>

	* The changes below fix SF bugs [593810], and [718045].

	* generic/tclIO.c (Tcl_CutChannel, Tcl_SpliceChannel):
	  Invoke TclpCutSockChannel and TclpSpliceSockChannel.

	* generic/tclInt.h: Declare TclpCutSockChannel and
	  TclpSpliceSockChannel.

	* unix/tclUnixSock.c (TclpCutSockChannel, TclpSpliceSockChannel):
	  Dummy functions, on unix the sockets are _not_ handled
	  specially.

	* mac/tclMacSock.c (TclpCutSockChannel, TclpSpliceSockChannel):
	* win/tclWinSock.c (TclpCutSockChannel, TclpSpliceSockChannel):
	  New functions to handle socket specific cut/splice operations:
	  auto-initi of socket system for thread on splice, management of
	  the module internal per-thread list of sockets, management of
	  association of sockets with HWNDs for event notification.

	* win/tclWinSock.c (NewSocketInfo): Extended initialization
	  assignments to cover all items of the structure. During
	  debugging of the new code mentioned above I found that two
	  fileds could contain bogus data.

	* win/tclWinFile.c: Added #undef HAVE_NO_FINDEX_ENUMS before
	  definition because when compiling in debug mode the compiler
	  complains about a redefinition, and this warning is also treated
	  as an error.

2003-04-21  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:  When the return code of a test does
	not meet expectations, report that as the reason for test failure,
	and do not attempt to check the test result for correctness.
	[Bug 725253]

2003-04-18  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinInt.h (VER_PLATFORM_WIN32_CE): conditionally define.
	* win/tclWinInit.c: recognize Windows CE as a Win platform.
	This just recognizes CE - full support will come later.

	* win/configure: regen
	* win/configure.in (SHELL): force it to /bin/sh as autoconf 2.5x
	uses /bin/bash, which can fail to find exes in the path (ie: lib).

	* generic/tclExecute.c (ExprCallMathFunc): remove incorrect
	extraneous cast from Tcl_WideAsDouble.

2003-04-18  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/open.n:		Moved serial port options from [fconfigure]
	* doc/fconfigure.n:	to [open] as it is up to the creator of a
				channel to describe the channel's special
				config options. [Bug 679010] 

2003-04-16  Don Porter  <dgp@users.sourceforge.net>

	* generic/tcl.h:	Made changes so that the "wideInt" Tcl_ObjType
	* generic/tclObj.c:	is defined on all platforms, even those where
	* generic/tclPort.h:	TCL_WIDE_INT_IS_LONG is defined.  Also made
	the Tcl_Value struct have a wideValue field on all platforms.  This is
	a ***POTENTIAL INCOMPATIBILITY*** for TCL_WIDE_INT_IS_LONG platforms
	because that struct changes size.  This is the same TIP 72
	incompatibility that was seen on other platforms at the 8.4.0 release,
	when this change should have happened as well.	[Bug 713562]

	* generic/tclInt.h:  New internal macros TclGetWide() and
	TclGetLongFromWide() to deal with both forms of the "wideInt"
	Tcl_ObjType, so that conditional TCL_WIDE_INT_IS_LONG code
	is confined to the header file.

	* generic/tclCmdAH.c:	Replaced most coding that was conditional
	* generic/tclCmdIL.c:	on TCL_WIDE_INT_IS_LONG with code that
	* generic/tclExecute.c: works across platforms, sometimes using
	* generic/tclTest.c:	the new macros above to do it.
	* generic/tclUtil.c:
	* generic/tclVar.c:

2003-04-17  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/socket.n: Added a paragraph to remind people to specify
	their encodings when using sockets. [Bug 630621]

2003-04-16  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/CrtMathFnc.3: Functions also have to deal with wide ints,
	but this was not documented. [Bug 709720]

2003-04-16  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: removed undesired 'static' for function
	which is now shared (previously it was duplicated).

2003-04-15  Joe English  <jenglish@users.sourceforge.net>
	* doc/namespace.n: added example section "SCOPED SCRIPTS",
	supplied by Kevin Kenny. (Fixes [Bug 219183])

2003-04-15  Kevin Kenny  <kennykb@acm.org>

	* makefile.vc: Updated makefile.vc to conform with Mo DeJong's
	changes to Makefile.in and tclWinPipe.c on 2003-04-14. Now passes
	TCL_PIPE_DLL in place of TCL_DBGX.
	* win/tclWinTime.c: Corrected use of types to make compilation
	compatible with VC++5.

2003-04-15  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: finished check-in from yesterday,
	removing duplicate function definition.

2003-04-14  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclClock.c:	Corrected compiler warnings.
	* generic/tclTest.c:

2003-04-14  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/Makefile.in: Don't define TCL_DBGX
	symbol for every compile. Instead, define
	TCL_PIPE_DLL only when compiling tclWinPipe.c.
	This will break other build systems, so
	they will need to remove the TCL_DBGX define
	and replace it with a define for TCL_PIPE_DLL.
	* win/tclWinPipe.c (TclpCreateProcess):
	Remove PREFIX_IDENT and DEBUG_IDENT from
	top of file. Use TCL_PIPE_DLL passed in
	from build env instead of trying to construct
	the dll name from already defined symbols.
	This approach is more flexible and better
	in the long run.

2003-04-14  Kevin Kenny  <kennykb@acm.org>

	* win/tclWinFile.c: added conditionals to restore compilation on
	VC++6, which was broken by recent changes.

2003-04-14  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: 
	* generic/tclPathObj.c: 
	* generic/tclFileSystem.h: overlooked one function which
	was duplicated, so this is now shared between modules.
	* win/tclWinFile.c: allow this file to compile with VC++ 5.2 again
	since Mingw build fixes broke that.

2003-04-13  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/configure.in: Add check for FINDEX_INFO_LEVELS
	from winbase.h, known to be a problem in VC++ 5.2.
	Define HAVE_NO_FINDEX_ENUMS if the define does not
	exist.
	* win/tclWinFile.c: Put declarations for
	FINDEX_INFO_LEVELS and FINDEX_SEARCH_OPS inside
	a check for HAVE_NO_FINDEX_ENUMS so that these are
	not declared twice. This fixes the Mingw build.
	* win/tclWinTime.c: Rework the init of timeInfo
	so that the number or initializers matches the
	declaration. This was broken under Mingw. Add
	cast to avoid compile warning when calling the
	AccumulateSample function.

2003-04-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/Makefile.in (GENERIC_OBJS): add missing tclPathObj.c

2003-04-12  Kevin Kenny  <kennykb@acm.org>

	* doc/clock.n:
	* generic/tclClock.c (Tcl_ClockObjCmd): 
	* tests/clock.test: Implementation of TIP #124. Also renumbered
	test cases to avoid duplicates [Bug 710310].
	* tests/winTime.test:
	* win/tclWinTest.c (TestwinclockCmd, TestwinsleepCmd):
	* win/tclWinTime.c (Tcl_WinTime, UpdateTimeEachSecond,
	                    ResetCounterSamples, AccumulateSample,
	                    SAMPLES, TimeInfo): Made substantial changes
	to the phase-locked loop (replaced an IIR filter with an FIR one)
	in a quest for improved loop stability (Bug not logged at SF, but
	cited in private communication from Jeff Hobbs).

2003-04-11  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c (Tcl_StringObjCmd,STR_IS_INT):  Corrected
	inconsistent results of [string is integer] observed on systems
	where sizeof(long) != sizeof(int).  [Bug 718878]
	* tests/string.test: Added tests for Bug 718878.
	* doc/string.n: Clarified that [string is integer] accepts
	32-bit integers.

2003-04-11  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (UpdateInterest): When dropping interest in
	  TCL_READABLE now dropping interest in TCL_EXCEPTION too. This
	  fixes a bug where Expect detects eof on a file prematurely on
	  solaris 2.6 and higher. A much more complete explanation is in
	  the code itself (40 lines of comments for a one-line change :)

2003-04-11  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/cmdAH.test: fix test suite problem if /home is a symlink
	[Bug #703264]
	* generic/tclIOUtil.c: fix bad error message with 'cd ""'
	[Bug #704917]
	* win/tclWinFile.c: 
	* win/tclWin32Dll.c: 
	* win/tclWinInt.h: allow Tcl to differentiate between reparse
	points which are symlinks and mounted volumes, and correctly
	handle the latter. This involves some elaborate code to find
	the actual drive letter (if possible) corresponding to a mounted
	volume.  [Bug #697862]
	* tests/fileSystem.test: add constraints to stop tests running
	in ordinary tcl interpreter. [Bug #705675]

	* generic/tclIOUtil.c:
	* generic/tclPathObj.c: (new file)
	* generic/tclFileSystem.h: (new file)
	* win/makefile.vc:
	Split path object handling out of the virtual filesystem layer,
	into tclPathObj.c.  This refactoring cleans up the internal
	filesystem code, and will make any future optimisations and
	forthcoming better thread-safety much easier.

	* generic/tclTest.c:
	* tests/reg.test: added some 'knownBug' tests for problems in
	Tcl's regexp code with the TCL_REG_CAN_MATCH flag (see Bug #703709).  
	Code too impenetrable to fix right now, but a fix is needed 
	for tip113 to work correctly.

	* tests/fCmd.test
	* win/tclWinFile.c: added some filesystem optimisation to the
	'glob' implementation, and some new tests.

	* generic/tclCmdMZ.c: fix typo in comment

	* tests/winFile.test:
	* tests/ioUtil.test:
	* tests/unixFCmd.test: renumbered tests with duplicate numbers.
	(Bug #710361)

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

	* doc/binary.n: Fixed typo in [binary format w] desc. [Bug 718543]

2003-04-08  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdAH.c (Tcl_ErrorObjCmd): Strings are only empty if
	they have zero length, not if their first byte is zero, so fix
	test guarding Tcl_AddObjErrorInfo to take this into account.  [Bug
	reported by Don Porter; no bug-id.]

2003-04-07  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileIfCmd):  Corrected string limits of
	arguments interpolated in error messages. [Bug 711371]

	* generic/tclCmdMZ.c (TraceExecutionProc):  Added missing
	Tcl_DiscardResult() call to avoid memory leak.

2003-04-07  Donal K. Fellows  <zzcgudf@ernie.mvc.mcc.ac.uk>

	* generic/tclDictObj.c (Tcl_DictObjCmd): Stopped compilers from
	moaning about switch fall-through.  [Bug 716327]
	(DictFilterCmd): Yet more warning killing, this time reported by
	Miguel Sofer by private chat.

2003-04-07  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/dict.test (dict-2.6): 
	* generic/tclDictObj.c (Tcl_NewDictObj, Tcl_DbNewDictObj): Oops!
	Failed to fully initialise the Dict structure.
	(DictIncrCmd): Moved valueAlreadyInDictionary label to stop
	compiler complaints.  [Bug 715751]

	* generic/tclDictObj.c (DictIncrCmd): Followed style in the rest of
	the core by commenting out wide-specific operations on platforms
	where wides are longs, and used longs more thoroughly than ints
	through [dict incr] anyway to forestall further bugs.
	* generic/tclObj.c: Made sure there's always a tclWideIntType
	implementation available, not that it is always useful.  [Bug 713562]

2003-04-05  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclDictObj.c: Removed commented out notes on
	declarations to be moved to elsewhere in the Tcl core.

	* generic/tclInt.h:	Final stages of plumbing in.
	* generic/tclBasic.c: 
	* generic/tclObj.c (TclInitObjSubsystem): 

	* unix/Makefile.in, win/Makefile.in, win/makefile.[bv]c: Build support.
	* generic/tcl.decls: Added dict public API to stubs table.
	* generic/tcl.h (Tcl_DictSearch): Added declaration of structure
	to allow user code to iterate over dictionaries.

	* doc/DictObj.3:	New files containing dictionary
	* doc/dict.n:		implementation, documentation and tests
	* generic/tclDictObj.c:	as mandated by TIP #111.
	* tests/dict.test:

2003-04-03  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure:
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Don't set
	TCL_LIBS if it is already set to support
	use of TCL_LIBS var from tclConfig.sh in
	the Tk configure script.

2003-04-03  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in: Don't subst MATH_LIBS,
	LIBS, and DL_LIBS separately. Instead, just
	subst TCL_LIBS since it includes the others.
	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS, SC_TCL_LINK_LIBS):
	Set and subst TCL_LIBS in SC_CONFIG_CFLAGS instead
	of SC_TCL_LINK_LIBS. Don't subst MATH_LIBS
	since it is now covered by TCL_LIBS.
	* unix/tclConfig.sh.in: Use TCL_LIBS instead
	of DL_LIBS, LIBS, and MATH_LIBS.
	* unix/dltest/Makefile.in: Ditto.

2003-04-03  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileReturnCmd):  Now that [return]
	compiles to INST_RETURN, it is safe to compile even outside a proc.

2003-04-02  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/configure.in: Set stub lib flag based
	on new LIBFLAGSUFFIX variable.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Set new
	LIBFLAGSUFFIX that works like LIBSUFFIX,
	it is used when creating library names.
	The previous implementation would generate
	-ltclstub85 instead of -ltclstub85s when
	configured with --disable-shared.

2003-04-02  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclParse.c (TclSubstTokens):  Moved declaration of
	utfCharBytes to beginning of procedure so that it does not go
	out of scope (get free()d) while append is still pointing to it.
	[Bugs 703167, 713754]

2003-04-01  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Check for
	inet_ntoa in -lbind inside the BeOS block since
	doing it later broke the build under SuSE 7.3.
	[Bug 713128]

2003-04-01  Don Porter  <dgp@users.sourceforge.net>

	* tests/README:  Direct [source] of *.test files is no longer
	recommended.  The tests/*.test files should only be evaluated under
	the control of the [runAllTests] command in tests/all.tcl.

	* generic/tclExecute.c (INST_RETURN):  Bytecompiled [return] failed
	to reset iPtr->returnCode, causing tests parse-18.17 and parse-18.21
	to fail strangely.
	* tests/parse.test (parse-18.21):  Corrected now functioning test.
	Added further coverage tests.

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

	* tests/parse.test (parse-18.*):  Coverage tests for the new
	implementation of Tcl_SubstObj().  Note that tests parse-18.17 and
	parse-18.21 demonstrate some bugs left to fix in the current code.

2003-03-27  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Use -Wl,--export-dynamic
	instead of -rdynamic for LDFLAGS. The -rdynamic is
	not documented so it seems better to pass the
	--export-dynamic flag to the linker.
	[Patch 573395]

2003-03-27  Miguel Sofer <msofer@users.sf.net>

	* tests/encoding.test:
	* tests/proc-old.test:
	* tests/set-old.test: Altered test numers to eliminate duplicates,
	[Bugs 710313, 710320, 710352]

2003-03-27  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

2003-03-26  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS, SC_TCL_LINK_LIBS):
	Add BeOS system to SC_CONFIG_CFLAGS. Check for
	inet_ntoa in -lbind, needed for BeOS.

2003-03-26  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n:
	* library/tcltest/tcltest.tcl:  Added reporting during
	[configure -debug 1] operations to warn about multiple uses of
	the same test name.  [FR 576693]

	* tests/msgcat.test (msgcat-2.2.1): changed test name to avoid
	duplication.  [Bug 710356]

	* unix/dltest/pkg?.c:  Changed all Tcl_InitStubs calls to pass
	argument exact = 0, so that rebuilds are not required when Tcl
	bumps to a new version.  [Bug 701926]

2003-03-24  Miguel Sofer <msofer@users.sf.net>

	* generic/tclVar.c:
	* tests/var.test: fixing ObjMakeUpvar's lookup algorithm for the
	created local variable, bugs #631741 (Chris Darroch) and #696893
	(David Hilker). 

2003-03-24  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* library/dde/pkgIndex.tcl: bumped version to 1.2.2 in tclWinDde.c,
	 now adding here too.

2003-03-22  Kevin Kenny  <kennykb@acm.org>

	* library/dde/pkgIndex.tcl:
	* library/reg/pkgIndex.tcl: Fixed a bug where [package require dde]
	or [package require registry] attempted to load the release version
	of the DLL into a debug build. [Bug 708218] Thanks to Joe Mistachkin
	for the patch.
	* win/makefile.vc: Added quoting around the script name in the
	'test' target; Joe Mistachkin insists that he has a configuration
	that fails to launch tcltest without it, and it appears harmless 
	otherwise.

2003-03-22  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/tclWinDde.c: Make dde services conform the the documentation
	such that giving only a topic name really returns all services
	with that topic. [Bug 219155]
	Prevent hangup caused by dde server applications failing to process
	messages [Bug 707822]
	* tests/winDde.test: Corrected labels and added a test for search
	by topic name.

2003-03-20  Don Porter  <dgp@users.sourceforge.net>

	* unix/tclUnixNotfy.c (Tcl_SetTimer,Tcl_WaitForEvent,
		Tcl_CreateFileHandler,Tcl_DeleteFileHandler):
	* win/tclWinNotify.c (Tcl_SetTimer,Tcl_WaitForEvent):  Some linkers
	apparently use a different representation for a pointer to a function
	within the same compilation unit and a pointer to a function in a
	different compilation unit.  This causes checks like those in the
	original notifier procedures to fall into infinite loops.  The fix
	is to store pointers to the original notifier procedures in a struct
	defined in the same compilation unit as the stubs tables, and compare
	against those values.  [Bug 707174]

	* generic/tclInt.h:  Removed definition of ParseValue struct that
	is no longer used.

2003-03-19  Don Porter  <dgp@users.sourceforge.net>

	* library/auto.tcl:		Replaced [regexp] and [regsub] with

	* generic/tclCompCmds.c (TclCompileReturnCmd):  Alternative fix for

	* generic/tclCompile.h (INST_RETURN):	bytecode INST_RETURN to
	* generic/tclExecute.c (INST_RETURN):	properly bytecode the
	[return] command to something that returns TCL_RETURN.

2003-03-18  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/configure.in: Don't run the AC_CYGWIN
	macro since it uses AC_CANONICAL_HOST under
	autoconf 2.5X. Just check to see if __CYGWIN__
	is defined by the compiler and set the
	ac_cv_cygwin variable based on that.
	[Bug 705912]

2003-03-18  Kevin Kenny  <kennykb@users.sourceforge.net>

	* tests/registry.test: Changed the conditionals to avoid an
	abort if [testlocale] is missing, as when running the test in
	tclsh rather than tcltest. [Bug #705677]

2003-03-18  Daniel Steffen  <das@users.sourceforge.net>

	* tools/tcltk-man2html.tcl: added support for building 'make html'
	from inside distribution directories named with 8.x.x version
	numbers. tcltk-man2html now uses the latest tcl8.x.x resp. tk8.x.x
	directories found inside its --srcdir argument.

2003-03-17  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/format.test: Renumber tests, a bunch of
	tests all had the same id.

2003-03-17  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/lsearch.n:	Altered documentation of -ascii options so
	* doc/lsort.n:		they don't specify that they operate on
				ASCII strings, which they never did
				anyway.  [Bug #703807]

2003-03-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Only add the modifier
	that indicates we've got a wide int when we're formatting in an
	integer style.  Stops some libc's from going mad.  [Bug #702622]
	Also tidied whitespace.

2003-03-13  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tcl.m4 (SC_WITH_TCL): Port version number
	fix that was made in tk instead of tcl sources.

2003-03-13  Mo DeJong  <mdejong@users.sourceforge.net>

	Require autoconf 2.57 or newer, see TIP 34
	for a detailed explanation of why this is good.
	This will no doubt break the build on some
	platforms, let the flaming begin.

	* tools/configure: Regen with autoconf 2.57.
	* tools/configure.in: Require autoconf 2.57.
	* unix/configure: Regen with autoconf 2.57.
	* unix/configure.in: Require autoconf 2.57.
	Apply AC_LIBOBJ changes from patch 529884.
	* unix/tcl.m4: Ditto.
	* win/configure: Regen with autoconf 2.57.
	* win/configure.in: Require autoconf 2.57.
	Don't subst LIBOBJS since this happens by
	default, this avoids an autoconf error.

	* generic/tclBasic.c (Tcl_EvalTokensStandard):
	* generic/tclCmdMZ.c (Tcl_SubstObj):

	* generic/tclParse.c (ParseTokens,Tcl_SubstObj,TclSubstTokens):
	* tests/subst.test (2.4, 8.7, 8.8, 11.4, 11.5):
	Substantial refactoring of Tcl_SubstObj to make use of the same
	parsing and substitution procedures as normal script evaluation.
	Tcl_SubstObj() moved to tclParse.c.  New routine TclSubstTokens()
	created in tclParse.c which implements all substantial functioning
	of Tcl_EvalTokensStandard().  TclCompileScript() loses its
	"nested" argument, the Tcl_Interp struct loses its termOffset
	field and the TCL_BRACKET_TERM flag in the evalFlags field, all
	of which were only used (indirectly) by Tcl_SubstObj().  Tests
	subst-8.7,8.8,11.4,11.5 modified to accomodate the only behavior
	change: reporting of parse errors now takes precedence over
	[return] and [continue] exceptions.  All other behavior should
	remain compatible.  [RFE 536831,684982] [Bug 685106]

	* generic/tcl.h:        Removed TCL_PREFIX_IDENT and TCL_DEBUG_IDENT
	* win/tclWinPipe.c:     from tcl.h -- they are not part of Tcl's
	public interface.  Put them in win/tclWinPipe.c where they are used.

	* generic/tclInterp.c (Tcl_InterpObjCmd):       Corrected and added
	* tests/interp.test (interp-2.13):              test for option
	parsing beyond objc for [interp create --].  Thanks to Marco Maggi.
	[Bug 702383]

2003-03-11  Kevin Kenny  <kennykb@users.sourceforge.net>

	* win/makefile.vc: Added two missing uses of $(DBGX) so that
	tclpip8x.dll loads without panicking on Win9x.

2003-03-09  Kevin Kenny  <kennykb@users.sourceforge.net>

	* generic/tclTest.c (TestChannelCmd): Removed an unused local
	variable that caused compilation problems on some platforms.

2003-03-08  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n:  Added missing "-body" to example.  Thanks to
	Helmut Giese.  [Bug 700011]

2003-03-07  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/io.test:
	* tests/ioCmd.test: Define a fcopy constraint and add
	it to the constraint list of any test that depends
	on the fcopy command. This is only useful to
	Jacl which does not support fcopy.

2003-03-07  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/encoding.test: Name temp files *.tcltestout
	instead of *.out so that when they are removed later,
	we don't accidently toast any files named *.out that
	the user has created in the build directory.

2003-03-07  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdAH.c (Tcl_FileObjCmd): Fix the setting of a file's
	mtime and atime on 64-bit platforms.  [Bug #698146]

2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/io.test: Doh! Undo accidental commenting
	out of a couple of tests.

2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/io.test: Define a fileevent constraint and add
	it to the constraint list of any test that depends
	on the fileevent command. This is only useful to
	Jacl which does not support fileevent.

2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/io.test: Define an openpipe constraint and add
	it to the constraint list of any test that creates
	a pipe using the open command. This is only useful to
	Jacl which does not support pipes.

2003-03-06  Don Porter  <dgp@users.sourceforge.net>

	* generic/TclUtf.c (Tcl_UniCharNcasecmp):       Corrected failure to
	* tests/utf.test (utf-25.*):    properly compare Unicode strings of
	different case in a case insensitive manner.  [Bug 699042]

2003-03-06  Kevin Kenny  <kennykb@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileSwitchCmd):
	Replaced a non-portable 'bzero' with a portable 'memset'.
	[Bug 698442].

2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIO.c (Tcl_Seek, Tcl_OutputBuffered):
	If there is data buffered in the statePtr->curOutPtr
	member then set the BUFFER_READY flag in Tcl_Seek.
	This is needed so that the next call to FlushChannel
	will write any buffered bytes before doing the seek.
	The existing code would set the BUFFER_READY flag
	inside the Tcl_OutputBuffered function. This was a
	programming error made when Tcl_OutputBuffered
	was originally created in CVS revision 1.35. The
	setting of the BUFFER_READY flag should not have
	been included in the Tcl_OutputBuffered function.
	* generic/tclTest.c (TestChannelCmd): Use the
	Tcl_InputBuffered and Tcl_OutputBuffered
	util methods to query the amount of buffered
	input and output.

2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIO.c (Tcl_Flush): Compare the
	nextAdded member of the ChannelBuffer to the
	nextRemoved member to determine if any output
	has been buffered. The previous check against
	the value 0 seems to have just been a coding
	error. See other methods like Tcl_OutputBuffered
	for examples where nextAdded is compared to
	nextRemoved to find the number of bytes buffered.

2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIO.c (Tcl_GetsObj): Check that
	the eol pointer has not gone past the end
	of the string when in auto translation
	mode and the INPUT_SAW_CR flag is set.
	The previous code worked because the
	end of string value \0 was being compared
	to \n, this patch just skips that pointless
	check.

2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIO.c (WriteBytes, WriteChars,
	Tcl_GetsObj, ReadBytes): Rework calls to
	TranslateOutputEOL to make it clear that
	a boolean value is being returned.
	Add some comments in an effort to make
	the code more clear. This patch makes
	no functional changes.

2003-03-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIO.c (Tcl_SetChannelOption):
	Invoke the Tcl_SetChannelBufferSize method
	as a result of changing the -buffersize
	option to fconfigure. The previous
	implementation used some inlined code that
	reset the buffer size to the default size
	instead of ignoring the request as
	implemented in Tcl_SetChannelBufferSize.
	* tests/io.test: Update test case so that
	it actually checks the implementation of
	Tcl_SetChannelBufferSize.

2003-03-05  David Gravereaux  <davygrvy@pobox.com>

	* win/rules.vc: updated default tcl version to 8.5.

2003-03-05  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCompCmds.c (TclCompileSwitchCmd): First attempt at a
	bytecode-compiled switch command.  It only handles the most common
	case of switching, but that should be enough for this to speed up
	a lot of people's code.  It is expected that the speed gains come
	from two things: better handling of the switch itself, and
	integrated compilation of the arms instead of embedding separate
	bytecode sequences (i.e. better local variable handling.)
	* tests/switch.test (switch-10.*): Tests of both uncompiled and
	compiled switch behaviour. [Patch #644819]

	* generic/tclCompile.h (TclFixupForwardJumpToHere): Additional
	macro to make the most common kind of jump fixup a bit easier.

	skip potential directory separator at the beginning of addStrRep.
	* mac/tclMacChan.c (OpenFileChannel, CommonWatch): followup
	fixes to cut and splice implementation for file channels.
	* mac/tclMacFile.c (TclpUtime): pass native path to utime().
	* mac/tclMacFile.c (TclpObjLink): correctly implemented creation
	of alias files via new static proc CreateAliasFile().
	* mac/tclMacPort.h: define S_ISLNK macro to fix stat'ing of links.
	* mac/tclMacUtil.c (FSpLocationFromPathAlias): fix to enable
	stat'ing of broken links.

2003-03-03  Kevin Kenny  <kennykb@users.sourceforge.net>

	* win/Makefile.vc: corrected bug introduced by 'g' for debug builds.

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

	* library/dde/pkgIndex.tcl:	dde bumped to version 1.2.1 for
	* win/tclWinDde.c:		bundled release with Tcl 8.4.2

	* win/tclWinReg.c:		bundled release with Tcl 8.4.2

	* library/opt/pkgIndex.tcl:	updated package index to version 0.4.4

2003-02-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/configure:
	* win/configure.in: check for 'g' for debug build type, not 'd'.
	* win/rules.vc (DBGX): correct to use 'g' for nmake win makefile
	to match the cygwin makefile for debug builds. [Bug #635107]

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

	* doc/file.n: subcommand is 'file volumes' not 'file volume'

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

	* generic/tclIOUtil.c (MakeFsPathFromRelative): removed dead code
	check of typePtr (darley).

	* tests/winTime.test: added note about PCI hardware dependency
	issues with high performance clock.

2003-02-27  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/lsearch.test (lsearch-10.7): 
	* generic/tclCmdIL.c (Tcl_LsearchObjCmd): Stopped -start option
	from causing an option when used with an empty list.  [Bug #694232]

2003-02-26  Chengye Mao <chengye.geo@yahoo.com>

	* win/tclWinInit.c: fixed a bug in TclpSetVariables by initializing
	dwUserNameLen with the sizeof(szUserName) before calling GetUserName.
	Don't know if this bug has been recorded: it caused crash in starting
	Tcl or wish in Windows.

2003-02-26  Jeff Hobbs	<jeffh@ActiveState.com>

	* generic/tclCmdMZ.c (TraceCommandProc): Fix mem leak when
	deleting a command that had trace on it. [Bug #693564] (sofer)

2003-02-25  Don Porter	<dgp@users.sourceforge.net>

	* doc/pkgMkIndex.n:	Modified [pkg_mkIndex] to use -nocase matching
	* library/package.tcl:	of -load patterns, to better accomodate
	common user errors due to confusion between [package names] names
	and [info loaded] names.

2003-02-25  Andreas Kupries  <andreask@pliers.activestate.com>

	* tests/pid.test: See below [Bug #678412].
	* tests/io.test: Made more robust against spaces in paths
	[Bug #678400].

2003-02-25  Miguel Sofer <msofer@users.sf.net>

	* tests/execute.test: cleaning up testobj's at the end, to avoid
	  leak warning by valgrind.

	sign-bit propagation when scanning wide ints. [Bug #690774]

2003-02-21  Daniel Steffen  <das@users.sourceforge.net>

	* mac/tclMacChan.c (TclpCutFileChannel, TclpSpliceFileChannel):
	Implemented missing cut and splice procs for file channels.

2003-02-21  Don Porter  <dgp@users.sourceforge.net>

	* library/package.tcl (tclPkgUnknown):  Minor performance tweaks
	to reduce the number of [file] invocations.  Meant to improve
	startup times, at least a little bit.  [Patch 687906]

2003-02-20  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4:
	* unix/tclUnixPipe.c: (macosx) use vfork() instead of fork() to
	create new processes, as recommended by Apple (vfork can be up to
	100 times faster thank fork on macosx).
	* unix/configure: regen.

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

	* generic/tclEncoding.c (LoadTableEncoding):
	* library/encoding/cp932.enc:      Correct jis round-trip encoding
	* library/encoding/euc-jp.enc:     by adding 'R' type to .enc files.
	* library/encoding/iso2022-jp.enc: [Patch #689341] (koboyasi, taguchi)
	* library/encoding/jis0208.enc:
	* library/encoding/shiftjis.enc:
	* tests/encoding.test:

	* unix/tclUnixChan.c (Tcl_MakeTcpClientChannel): add
	MakeTcpClientChannelMode that takes actual mode flags to avoid
	hang on OS X (may be OS X bug, but patch works x-plat).
	[Bug #689835] (steffen)

2003-02-20  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/regsub.n: Typo fix [Bug #688943]

2003-02-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixThrd.c (TclpReaddir):
	* unix/tclUnixPort.h: update to Bug 689100 patch to ensure that
	there is a defined value of MAXNAMLEN (aka NAME_MAX in POSIX) and
	that we have some buffer allocated.

2003-02-19  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclStringObj.c: restored Tcl_SetObjLength() side-effect
	of always invalidating unicode rep (if the obj has a string rep).
	Added hasUnicode flag to String struct, allows decoupling of
	validity of unicode rep from buffer size allocated to it (improves 
	memory allocation efficiency). [Bugs #686782, #671138, #635200]

	* macosx/Tcl.pbproj/project.pbxproj:
	* macosx/Makefile: reworked embedded build to no longer require
	relinking but to use install_name_tool instead to change the
	install_names for embedded frameworks. [Bug #644510]

	* macosx/Tcl.pbproj/project.pbxproj: preserve mod dates when
	running 'make install' to build framework (avoids bogus rebuilds
	of dependent frameworks because tcl headers appear changed).

	* tests/ioCmd.test (iocmd-1.8): fix failure when system encoding
	is utf-8: use iso8859-1 encoding explicitly.

2003-02-18  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c (TclCompileExprWords): remove unused
	variable "range" [Bug 664743]
	* generic/tclExecute.c (ExprSrandFunc): remove unused
	variable "result" [Bug 664743]
	* generic/tclStringObj.c (UpdateStringOfString): remove unused
	variable "length" [Bug 664751]
	* tests/execute.test (execute-7.30): fix for [Bug 664775]

2003-02-18  Andreas Kupries  <andreask@activestate.com>

	* unix/tcl.m4: [Bug #651811] Added definition of _XOPEN_SOURCE and
	  linkage of 'xnet' library to HP 11 branch. This kills a lot of
	  socket-related failures in the testsuite when Tcl was compiled
	  in 64 bit mode (both PA-RISC 2.0W, and IA 64).

	* unix/configure: Regenerated.

2003-02-18  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclIO.c (HaveVersion): correctly decl static

	* unix/tclUnixThrd.c (TclpReaddir): reduce size of name string in
	tsd to NAME_MAX instead of PATH_MAX. [Bug #689100] (waters)

2003-02-18  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_ENABLE_THREADS): Make sure
	-lpthread gets passed on the link line when
	checking for the pthread_attr_setstacksize symbol.

2003-02-18  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclTest.c: cleanup of new 'simplefs' test code, and
	better documentation.

2003-02-17  Miguel Sofer <msofer@users.sf.net>

	* generic/tclBasic.c (TclRenameCommand): fixing error in previous
	commit. 

2003-02-17  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclExecute.c (TclExecuteByteCode INST_STR_MATCH):
	* generic/tclCmdMZ.c (Tcl_StringObjCmd STR_MATCH):
	* generic/tclUtf.c (TclUniCharMatch):
	* generic/tclInt.decls:  add private TclUniCharMatch function that
	* generic/tclIntDecls.h: does string match on counted unicode
	* generic/tclStubInit.c: strings.  Tcl_UniCharCaseMatch has the
	* tests/string.test:     failing that it can't handle strings or
	* tests/stringComp.test: patterns with embedded NULLs.  Added
	tests that actually try strings/pats with NULLs.  TclUniCharMatch
	should be TIPed and made public in the next minor version rev.

2003-02-17  Miguel Sofer <msofer@users.sf.net>

	* generic/tclBasic.c (TclRenameCommand): 'oldFullName' object was
	not being freed on all function exits, causing a memory leak 
	[Bug 684756]

2003-02-17  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIO.c (Tcl_GetsObj): Minor change
	so that eol is only assigned at the top of the
	TCL_TRANSLATE_AUTO case block. The other cases
	assign eol so this does not change any functionality.

2003-02-17  Kevin Kenny  <kennykb@users.sourceforge.net>

	* tests/notify.test: Removed Windows line terminators. [Bug 687913].

2003-02-15  Miguel Sofer <msofer@users.sf.net>

	* generic/tclBasic.c (Tcl_EvalEx):
	* generic/tclCompExpr.c (CompileSubExpr):
	* generic/tclCompile.c (TclCompileScript):
	* generic/tclParse.c (Tcl_ParseCommand, ParseTokens):

	* tests/main.test (3.4):
	* tests/misc.test (1.2):
	* tests/parse.test (6.18):
	* tests/parseExpr.test (15.35):
	* tests/subst.test (8.6): Don Porter's fix for bad parsing of
	nested scripts [Bug 681841].

2003-02-15  Kevin Kenny  <kennykb@users.sourceforge.net>

	* tests/notify.test (new-file): 
	* generic/tclTest.c (TclTest_Init, EventtestObjCmd, EventtestProc,
	                     EventTestDeleteProc):
	* generic/tclNotify.c (Tcl_DeleteEvents): Fixed Tcl_DeleteEvents
	not to get a pointer smash when deleting the last event in the
	queue. Added test code in 'tcltest' and a new file of test cases
	'notify.test' to exercise this functionality; several of the new
	test cases fail for the original code and pass for the corrected
	code. [Bug 673714]

	* unix/tclUnixTest.c (TestfilehandlerCmd): Corrected a couple
	of typos in error messages. [Bug 596027]

2003-02-14  Jeff Hobbs  <jeffh@ActiveState.com>

	* README:		Bumped to version 8.4.2.
	* generic/tcl.h:
	* tools/tcl.wse.in:
	* unix/configure:
	* unix/configure.in:
	* unix/tcl.m4:
	* unix/tcl.spec:
	* win/README.binary:
	* win/configure:
	* win/configure.in:
	* macosx/Tcl.pbproj/project.pbxproj:

	* generic/tclStringObj.c (Tcl_GetCharLength): perf tweak

	* unix/tcl.m4: correct HP-UX ia64 --enable-64bit build flags

2003-02-14  Kevin Kenny  <kennykb@users.sourceforge.net>

	* win/tclWinTime.c: Added code to test and compensate for
	forward leaps of the performance counter. See the MSDN Knowledge
	Base article Q274323 for the hardware problem that makes this
	necessary on certain machines.
	* tests/winTime.test: Revised winTime-2.1 - it had a tolerance
	of thousands of seconds, rather than milliseconds. (What's six
	orders of magnitude among friends?
	Both the above changes are triggered by a problem reported at
	http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/1536811
	although the developers find it difficult to believe that it
	accounts for the observed behavior and suspect a fault in the
	RTC chip.

2003-02-13  Kevin Kenny  <kennykb@users.sourceforge.net>

	* win/tclWinInit.c: Added conversion from the system encoding
	to tcl_platform(user), so that it works with non-ASCII7 user names.
	[Bug 685926]

	* doc/tclsh.1: Added language to describe the handling of the
	end-of-file character \u001a embedded in a script file.
	[Bug 685485]

2003-02-11  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/fileName.test:
	* unix/tclUnixFile.c: fix for [Bug 685445] when using 'glob -l'
	on broken symbolic links.  Added two new tests for this bug.

2003-02-11  Kevin Kenny  <kennykb@users.sourceforge.net>

	* tests/http.test: Corrected a problem where http-4.14 would fail
	when run in an environment with a proxy server.  Replaced references
	to scriptics.com by tcl.tk.

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

	* tests/lsearch.test:
	* generic/tclCmdIL.c (Tcl_LsearchObjCmd): protect against the case
	that lsearch -regepx list and pattern objects are equal.

	* tests/stringObj.test:
	* generic/tclStringObj.c (Tcl_GetCharLength): correct ascii char
	opt of 2002-11-11 to not stop early on \x00. [Bug #684699]

	* tests.parse.test: remove excess EOF whitespace

	* generic/tclParse.c (CommandComplete): more paranoid check to
	break on (p >= end) instead of just (p == end).

2003-02-11  Miguel Sofer <msofer@users.sf.net>

	* generic/tclParse.c (CommandComplete): 
	* tests/parse.test: fix for [Bug 684744], by Don Porter.

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

	* generic/tclIOUtil.c (Tcl_FSJoinPath, Tcl_FSGetNormalizedPath): 
	(UpdateStringOfFsPath): revert the cwdLen == 0 check and instead
	follow a different code path in Tcl_FSJoinPath.
	(Tcl_FSConvertToPathType, Tcl_FSGetNormalizedPath):
	(Tcl_FSGetFileSystemForPath): Update string rep of path objects
	before freeing the internal object. (darley)

	* tests/fileSystem.test: added test 8.3
	* generic/tclIOUtil.c (Tcl_FSGetNormalizedPath): 
	(UpdateStringOfFsPath): handle the cwdLen == 0 case 

	* unix/tclUnixFile.c (TclpMatchInDirectory): simplify the hidden
	file match check.

2003-02-10  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure:
	* win/configure.in: Generate error when attempting
	to build under Cygwin. The Cygwin port of Tcl/Tk
	does not build and people are filing bug reports
	under the mistaken impression that someone is
	actually maintaining the Cygwin port. A post to
	comp.lang.tcl asking someone to volunteer as an
	area maintainer has generated no results.
	Closing bugs 680840, 630199, and 634772 and
	marking as "Won't fix".

2003-02-10  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/append.n: Return value was not documented. [Bug 683188]

2003-02-10  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/FileSystem.3:
	* generic/tclIOUtil.c:
	* generic/tclInt.h:
	* tests/fileSystem.test:
	* unix/tclUnixFCmd.c:
	* unix/tclUnixFile.c:
	* win/tclWinFile.c: further filesystem optimization, applying
	[Patch 682500].	 In particular, these code examples are
	faster now:
	foreach f $flist { if {[file exists $f]} {file stat $f arr;...}}
	foreach f [glob -dir $dir *] { # action and/or recursion on $f }
	cd $dir
	foreach f [glob *] { # action and/or recursion on $f }
	cd ..

	* generic/tclTest.c: Fix for [Bug 683181] where test suite
	left files in 'tmp'.

2003-02-08  Jeff Hobbs  <jeffh@ActiveState.com>

	* library/safe.tcl: code cleanup of eval and string comp use.

2003-02-07  Vince Darley  <vincentdarley@users.sourceforge.net>

	* win/tclWinFCmd.c: cleanup long lines
	* win/tclWinFile.c: sped up pure 'glob' by a factor of 2.5
	('foreach f [glob *] { file exists $f }' is still slow)
	* tests/fileSystem.text:
	* tests/fileName.test: added new tests to ensure correct
	behaviour in optimized filesystem code.

2003-02-07  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclTest.c:
	* tests/fileSystem.text: fixed test 7.2 to avoid a possible
	crash, and not change the pwd.

	* tests/http.text: added comment to test 4.15, that it may
	fail if you use a proxy server.

2003-02-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileIncrCmd):
	* tests/incr.test: Don't include the text
	"(increment expression)" in the errorInfo
	generated by the compiled version of the
	incr command since it does not match the
	message generated by the non-compiled version
	of incr. It is also not possible to match
	this error output under Jacl, which does
	not support a compiler.

2003-02-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclExecute.c (TclExecuteByteCode): When an
	error is encountered reading the increment value during
	a compiled call to incr, add a "(reading increment)"
	error string to the errorInfo variable. This makes
	the errorInfo variable set by the compiled incr command
	match the value set by the non-compiled version.
	* tests/incr-old.test: Change errorInfo result for
	the compiled incr command case to match the modified
	implementation.
	* tests/incr.test: Add tests to make sure the compiled
	and non-compiled errorInfo messages are the same.

2003-02-06  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:  Filename arguments to [outputChannel]
	and [errorChannel] (also -outfile and -errfile) were [open]ed but
	never [closed].  Also, [cleanupTests] could remove output or error
	files.  [Bug 676978].
	* library/tcltest/pkgIndex.tcl: Bumped to version 2.2.2.

2003-02-05  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/interp.test:
	* tests/set-old.test: Run test cases that depend
	on hash order through lsort so that the tests
	also pass under Jacl. Does not change test
	results under Tcl.

2003-02-04  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c:
	* generic/tclEvent.c:
	* generic/tclInt.h:
	* mac/tclMacFCmd.c:
	* unix/tclUnixFCmd.c:
	* win/tclWin32Dll.c:
	* win/tclWinFCmd.c:
	* win/tclWinInit.c:
	* win/tclWinInt.h:
	* tests/fileSystem.test: fix to finalization/unloading/encoding
	issues to make filesystem much less dependent on encodings for
	its cleanup, and therefore allow it to be finalized later in the
	exit process.  This fixes fileSystem.test-7.1.  Also fixed one
	more bug in setting of modification dates of files which have 
	undergone cross-platform copies.  [Patch 676271]

	* tests/basic.test:
	* tests/exec.test:
	* tests/fileName.test:
	* tests/io.test: fixed some test failures when tests are run 
	from a directory containing spaces.

	* tests/fileSystem.test:
	* generic/tclTest.c: added regression test for the modification
	date setting of cross-platform file copies.

2003-02-03  Kevin Kenny  <kennykb@users.sourceforge.net>

	* generic/tclBasic.c: Changed [trace add command] so that 'rename'
	callbacks get fully qualified names of the command. [Bug
	651271]. ***POTENTIAL INCOMPATIBILITY***
	* tests/trace.test: Modified the test cases for [trace add
	command] to expect fully qualified names on the 'rename'
	callbacks. Added a case for renaming a proc within a namespace.
	* doc/trace.n: Added language about use of fully qualified names
	in trace callbacks.

2003-02-01  Kevin Kenny  <kennykb@users.sourceforge.net>

	* generic/tclCompCmds.c: Removed an unused variable that caused
	compiler warnings on SGI. [Bug 664379]

	* generic/tclLoad.c: Changed the code so that if Tcl_StaticPackage
	is called to report the same package as being loaded in two interps,
	it shows up in [info loaded {}] in both of them (previously,
	it didn't appear in the static package list in the second.

	* tests/load.test Added regression test for the above bug.
	[Bug 670042]

	* generic/tclClock.c: Fixed a bug that incorrectly allowed
	[clock clicks {}] and [clock clicks -] to be accepted as if
	they were [clock clicks -milliseconds].

	* tests/clock.test: Added regression tests for the above bug.
	[Bug 675356]

	* tests/unixNotfy.test: Added cleanup of working files
	[Bug 675609]

	* doc/Tcl.n: Added headings to the eleven paragraphs, to improve
	formatting in the tools that attempt to extract tables of contents
	from the manual pages. [Bug 627455]

	* generic/tclClock.c: Expanded mutex protection around the setting
	of env(TZ) and the thread-unsafe call to tzset(). [Bug 656660]

2003-01-31  Don Porter  <dgp@users.sourceforge.net>

	* tests/tcltest.test: Cleaned up management of file/directory
	creation/deletion to improve "-debug 1" output.  [Bug 675614]
	The utility [slave] command failed to properly [list]-quote a
	constructed [open] command, causing failure when the pathname
	contained whitespace.  [Bug 678415]

	* tests/main.test: Stopped main.test from deleting existing file.
	Test suite should not delete files that already exist. [Bug 675660]

2003-01-28  Don Porter  <dgp@users.sourceforge.net>

	* tests/main.test: Constrain tests that do not work on Windows.
	[Bug 674387]

2003-01-28  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: fix to setting modification date
	in TclCrossFilesystemCopy.  Also added 'panic' in 
	Tcl_FSGetFileSystemForPath under illegal calling circumstances
	which lead to hard-to-track-down bugs.

	* generic/tclTest.c: added test suite code to allow
	exercising a vfs-crash-on-exit bug in Tcl's finalization caused
	by the encodings being cleaned up before unloading occurs.
	* tests/fileSystem.test: added new 'knownBug' test 7.1
	to demonstrate the crash on exit.

2003-01-28  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tcl.h: Add TCL_PREFIX_IDENT and
	TCL_DEBUG_IDENT, used only by TclpCreateProcess.
	* unix/Makefile.in: Define TCL_DBGX.
	* win/Makefile.in: Define TCL_DBGX.
	* win/tclWinPipe.c (TclpCreateProcess):
	Check that the Tcl pipe dll actually exists
	in the Tcl bin directory and panic if it
	is not found. Incorporate TCL_DBGX into
	the Tcl pipe dll name. This fixes a really
	mysterious error that would show up when
	exec'ing a 16 bit application under Win95
	or Win98 when Tcl was compiled with symbols.
	The error seemed to indicate that the executable
	could not be found, but it was actually the
	Tcl pipe dll that could not be found.

2003-01-26  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/README: Update msys+mingw URL to release 6.
	This version bundles gcc 3.

2003-01-26  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/configure.in: Add test that checks to
	see if the compiler can cast to a union type.
	* win/tclWinTime.c: Squelch compiler warning
	about union initializer by casting to union
	type when compiling with gcc.

2003-01-25  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIO.c (Tcl_CutChannel, Tcl_SpliceChannel):
	Invoke TclpCutFileChannel and TclpSpliceFileChannel.
	* generic/tclInt.h: Declare TclpCutFileChannel
	and TclpSpliceFileChannel.
	* unix/tclUnixChan.c (FileCloseProc, TclpOpenFileChannel,
	Tcl_MakeFileChannel, TclpCutFileChannel,
	TclpSpliceFileChannel): Implement thread load data
	cut and splice for file channels. This avoids
	an invalid memory ref when compiled with -DDEPRECATED.
	* win/tclWinChan.c (FileCloseProc, TclpCutFileChannel,
	TclpSpliceFileChannel): Implement thread load data
	cut and splice for file channels. This avoids
	an invalid memory ref that was showing up in the
	thread extension.

2003-01-25  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWin32Dll.c (TclpCheckStackSpace, squelch_warnings):
	* win/tclWinChan.c (Tcl_MakeFileChannel, squelch_warnings):
	* win/tclWinFCmd.c (DoRenameFile, DoCopyFile, squelch_warnings):
	Re-implement inline ASM SEH handlers for gcc.
	The esp and ebp registers are now saved on the
	stack instead of in global variables so that
	the code is thread safe. Add additional checks
	when TCL_MEM_DEBUG is defined to be sure the
	values were recovered from the stack properly.
	Remove squelch_warnings functions and add
	a dummy call in the handler methods to squelch
	compiler warnings.

2003-01-25  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure:
	* win/configure.in: Define HAVE_ALLOCA_GCC_INLINE
	when we detect that no alloca function is found
	in malloc.h and we are compiling with GCC.
	Remove HAVE_NO_ALLOC_DECL define.
	* win/tclWin32Dll.c (TclpCheckStackSpace):
	Don't define alloca as a cdecl function.
	Doing this caused a tricky runtime bug because
	the _alloca function expects the size argument
	to be passed in a register and not on the stack.
	To fix this problem, we use inline ASM when
	compiling with gcc to invoke _alloca with the
	size argument loaded into a register.

2003-01-24  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinDde.c (Dde_Init): clarified use of tsdPtr.
	(DdeServerProc): better refcount handling of returnPackagePtr.

	* generic/tclEvent.c (Tcl_Finalize): revert finalize change on
	2002-12-04 to correct the issue with extensions that have TSD
	needing to finalize that before they are unloaded.  This issue
	needs further clarification.

	* tests/unixFCmd.test: only do groups check on unix

2003-01-24  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclStringObj.c: proper fixes for Tcl_SetObjLength and 
	Tcl_AttemptSetObjectLength dealing with string objects with
	both pure-unicode and normal internal representations. 
	Previous fix didn't handle all cases correctly.
	* generic/tclIO.c: Add 'Tcl_GetString()' to ensure the object has
	a valid 'objPtr->bytes' field before manipulating it directly.

	This fixes [Bug 635200] and [Bug 671138], but may reduce performance
	of Unicode string handling in some cases. A further patch will
	be applied to address this, once the code is known to be correct.

2003-01-24  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/configure.in: Add test to see if alloca
	is undefined in malloc.h.
	* win/tclWin32Dll.c (TclpCheckStackSpace): Rework
	the SEH exception handler logic to avoid using
	the stack since alloca will modify the stack.
	This was causing a nasty bug that would set the
	exception handler to 0 because it tried to pop
	the previous exception handler off the top of
	the stack.

2003-01-23  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/lset.n: Fixed fault in return values from lset in
	documentation examples [SF Bug #658463] and tidied up a bit at the
	same time.

2003-01-21  Joe English  <jenglish@users.sourceforge.net>
	* doc/namespace.n (namespace inscope): Clarified documentation
	[SF Patch #670110]

2003-01-21  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Set SHLIB_SUFFIX
	so that TCL_SHLIB_SUFFIX will be set to a useful
	value in the generated tclConfig.sh.
	Set SHLIB_LD_LIBS to "" or '${LIBS}' based on
	the --enable-shared flag. This matches the
	UNIX implementation.

2003-01-18  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCkalloc.c: change %ud to %u as appropriate.

2003-01-17  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWinDde.c (DdeServerProc): Deallocate
	the Tcl_Obj returned by ExecuteRemoteObject
	if it was not saved in a connection object.

2003-01-17  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tcl.h: Revert earlier change that
	defined TCL_WIDE_INT_TYPE as long long and
	TCL_LL_MODIFIER as L when compiling with
	mingw. This change ended up causing some
	test case failures when compiling with mingw.
	* generic/tclObj.c (UpdateStringOfWideInt):
	Describe the warning generated by mingw and
	why it needs to be ignored so that someone
	is not tempted to "fix" this problem again
	in the future.

2003-01-16  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclStringObj.c: Tcl_SetObjLength fix for when
	the object has a unicode string rep. Fixes [Bug 635200]
	* tests/stringObj.test: removed 'knownBug' constraint from
	test 14.1 now that this bug is fixed.

	* generic/tclInt.h:
	* generic/tclBasic.c:
	* generic/tclCmdMZ.z:
	* tests/trace.test: execution and command tracing bug fixes and
	cleanup.  In particular fixed [Bug 655645], [Bug 615043], 
	[Bug 571385]
	  - fixed some subtle cleanup problems with tracing. This 
	    required replacing Tcl_Preserve/Tcl_Release with a more 
	    robust refCount approach. Solves at least one known crash
	    caused by memory corruption.
	  - fixed some confusion in the code between new style traces
	  (Tcl 8.4) and the very limited 'Tcl_CreateTrace' which existed
	  before.
	  - made behaviour consistent with documentation (several
	    tests even contradicted the documentation before).
	  - fixed some minor error message details
	  - added a number of new tests

2003-01-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinSerial.c (SerialOutputProc): add casts for
	bytesWritten to allow strict compilation (no warnings).

	* tests/winDde.test:
	* win/tclWinDde.c (Tcl_DdeObjCmd): Prevent crash when empty
	service name is passed to 'dde eval' and goto errorNoResult in
	request and poke error cases to free up any allocated data.

2003-01-16  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWin32Dll.c (squelch_warnings): Squelch
	compiler warnings from SEH ASM code.
	* win/tclWinChan.c (squelch_warnings): Squelch
	compiler warnings from SEH ASM code.
	* win/tclWinDde.c: Add casts to avoid compiler
	warnings. Pass pointer to DWORD instead of int
	to avoid compiler warnings.
	* win/tclWinFCmd.c (squelch_warnings): Add casts
	and fixup decls to avoid compiler warnings.
	Squelch compiler warnings from SEH ASM code.
	* win/tclWinFile.c: Add casts and fixup decls
	to avoid compiler warnings. Remove unused variable.
	* win/tclWinNotify.c: Declare as DWORD instead
	of int to avoid compiler warning.
	* win/tclWinReg.c: Add casts to avoid compiler
	warning. Fix assignment in if expression bug.
	* win/tclWinSerial.c: Add casts to avoid compiler
	warnings. Remove unused variable.
	* win/tclWinSock.c: Add casts and fixup decls
	to avoid compiler warnings.

2003-01-14  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclClock.c (FormatClock): corrected typo that
	incorrectly conditionally defined savedTZEnv and savedTimeZone.

2003-01-13  Mo DeJong  <mdejong@users.sourceforge.net>

	Fix mingw build problems and compiler warnings.

	* generic/tcl.h: Add if defined(__MINGW32__)
	check to code that sets the TCL_WIDE_INT_TYPE
	and TCL_LL_MODIFIER.
	* generic/tclClock.c (FormatClock): Don't
	define savedTimeZone and savedTZEnv if
	we are not going to use them.
	* generic/tclEnv.c: Add cast to avoid warning.
	* win/tclWinChan.c: Use DWORD instead of int
	to avoid compiler warning.
	* win/tclWinThrd.c: Only define allocLock,
	allocLockPtr, and dataKey when TCL_THREADS
	is defined. This avoid a compiler warning
	about unused variables.

2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/README: Update msys + mingw URL, the
	new release includes the released 1.0.8
	version of msys which includes a number
	of bug fixes.

2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Pull in
	addition of shell32.lib to LIBS_GUI that
	was added to the Tk tcl.m4 but never made
	it back into the Tcl version.

2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tcl.h: Skip Tcl's define of CHAR,
	SHORT, and LONG when HAVE_WINNT_IGNORE_VOID
	is defined. This avoids a bunch of compiler
	warnings when building with Cygwin or Mingw.
	* win/configure: Regen.
	* win/configure.in: Define HAVE_WINNT_IGNORE_VOID
	when we detect a winnt.h that still defines
	CHAR, SHORT, and LONG when VOID has already
	been defined.
	* win/tcl.m4 (SC_LOAD_TCLCONFIG): Subst the
	TCL_DEFS loaded from tclConfig.sh so that
	Tcl defines can make it into the Tk Makefile.

	* win/configure: Regen.
	* win/configure.in: Check for typedefs like LPFN_ACCEPT
	in winsock2.h and define HAVE_NO_LPFN_DECLS if not found.
	* win/tclWinSock.c: Define LPFN_* typedefs if
	HAVE_NO_LPFN_DECLS is defined. This fixes the build
	under Mingw and Cygwin, it was broken by the changes
	made on 2002-11-26.

	* generic/tclIOUtil.c: 
	* win/tclWinInt.h:
	* win/tclWinInit.c: fix to new WinTcl crash on exit with vfs,
	introduced on 2002-12-06.  Encodings must be cleaned up after
	the filesystem.

	* win/makefile.vc: fix to minor VC++ 5.2 syntax problem

2003-01-09  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileReturnCmd):  Corrected off-by-one
	problem with recent commit.  [Bug 633204]

2003-01-09  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c: remove unused variable 'macSpecialCase'
	[Bug 664749]

	* generic/tclIOUtil.c:
	* generic/tclInt.h:
	* unix/tclUnixFile.c:
	* mac/tclMacFile.c:
	* win/tclWinFile.c:
	* win/tclWinInt.h:
	* win/tclWin32Dll.c: 
	* tests/cmdAH.test: fix to non-ascii chars in paths when
	setting mtime and atime through 'file (a|m)time $path $time'
	[Bug 634151]

2003-01-08  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c (TclExprFloatError):  Use the IS_NAN macro
	for greater clarity of code.

2003-01-07  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileReturnCmd): 
	* tests/compile.test:	Corrects failure of bytecompiled 
	[catch {return}] to have result TCL_RETURN (not TCL_OK) [Bug 633204].
	This patch is a workaround for 8.4.X.  A new opcode INST_RETURN is a
	better long term solution for 8.5 and later.

	* win/makefile.vc:
	* win/rules.vc:  Fixed INSTALLDIR macro problem that blanked itself
	by accident causing the install target to put the tree at the root
	of the drive built on.  Whoops..

	Renamed the 'linkexten' option to be 'staticpkg'.  Added 'thrdalloc'
	to allow the switching _on_ of the thread allocator.  Under testing,
	I found it not to be benificial under windows for the purpose of the
	application I was using it for.  It was more important for this app
	that resources for tcl threads be returned to the system rather than
	saved/moved to the global recycler.  Be extra clean or extra fast
	for the default threaded build?  Let's move to clean and allow it to
	be switched on for users who find it benificial for their use of
	threads.
