	* ChangeLog.1999:
	* ChangeLog: broke changes from 199x into ChangeLog.1999 to reduce
	size of the main ChangeLog.

2001-09-13  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* tests/ioCmd.test: Changed the computation of the result for
	  iocmd-8.1[123] so that the tests work for single- and
	  multi-process execution of the testsuite. Depending on the
	  choice of the user stdout is a tty or not and thus reports
	  different channel options. Fixes [460993] reported by Don
	  Porter.

2001-09-13  Miguel Sofer  <msofer@users.sourceforge.net>

	* doc/ParseCmd.3:  
	* generic/tcl.decls:
	* generic/tclCmdMZ.c (Tcl_SubstObjCmd):
	* generic/tclDecls.h:
	* generic/tclParse.c:
	* generic/tclStubInit.c:
	* tests/parse.test: Deprecate the use of Tcl_EvalTokens, replaced
	by the new Tcl_EvalTokensStandard. The new function performs the
	same duties but adheres to the standard return convention for Tcl
	evaluations; the deprecated function could only return TCL_OK or
	TCL_ERROR, which caused [Bug: 219384] and [Bug: 455151].
	This patch implements [TIP: 56].
	
2001-09-12  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4: Invert the logic that checks for $GCC.
	Instead of checking for "$GCC" = "no" we check for
	"$GCC" != "yes" or simply swap the true and false
	blocks of code in an if statement. That way if
	GCC is set to "" everything will still work. [Bug 460991]

2001-09-12  Don Porter <msofer@users.sourceforge.net>

	* tests/appendComp.test:
	* tests/lsearch.test:
	* tests/namespace.test:
	* tests/rename.test:
	* tests/split.test:  Corrected tests to better isolate tests in
	one file from influencing tests in other files.  [Bug 460591]

2001-09-12  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tcl.decls: reserved stub #481 for the implementation of
	[TIP 56]

2001-09-11  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* doc/OpenFileChnl.3: Added documentation for Tcl_WriteRaw and
	  Tcl_ReadRaw [#414929].
	
	* doc/CrtChannel.3: Added documentation for Tcl_ChannelBuffered
	  and Tcl_GetTopChannel [#414929].

	* The changes below are a fix for [219253].

	* tests/socket.test: Removed _most_ instances of hardwired port
	  numbers for listening sockets. Remaining are the ports in all
	  tests with constraint 'doTestsWithRemoteServer'. These seem to
	  be designed for a more controlled environment and are usually
	  skipped when running the testsuite.

	* tests/io.test: Removed all instances of hardwired port numbers
	  for listening sockets.

2001-09-10  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclEvent.c (TclInExit): Corrected handling of tsd in
	late stages of finalization.  [Bug #419449] (darley)

	* tests/stack.test:
	* generic/tclInterp.c (AliasObjCmd): Check the numLevels to ensure
	that we aren't hitting some alias loop condition.  [Bug #443184]

2001-09-10  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Don't include . characters
	in the Tcl library name when building on FreeBSD 3.X and later
	systems. [Patch 450725]

2001-09-10  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* doc/tclsh.1:
	* doc/Tcl_Main.3: 
	* doc/CrtChannel.3: 
	* doc/OpenFileChnl.3: 
	* doc/GetStdChan.3: Enhanced the manpages with cross-references to
	  the new manpage and more explanations how these functions deal
	  with the standard channels in various situations.

	* doc/StdChannels.3: New manpage describing handling of the
	  standard channels by the Tcl library [402725].

2001-09-10  Don Porter <dgp@users.sourceforge.net>

	* unix/mkLinks (Tcl_FSLink): Updated to reflect 2001-08-23
	file system changes.

	* unix/tclLoadShl.c:  Added #include of tclInt.h; access to Tcl
	internals, notably TclpUnloadFile(), is required.  Thanks to
	Bob Techentin for report and patch.  [Bug 459305]

	* generic/tclInitScript.h (initScript):
	* win/tclWinInit.c (TCL_REGISTRY_KEY, TclpSetVariables):  Removed
	vestiges of Tcl's old initialization from registry variables.
	[Bug 455645]

2001-09-10  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* generic/tclInt.decls: Also added 'TclWinFlushDirtyChannels' to
	  the internal platform specific stub table.

	* win/tclWinFile.c (TclpObjStat): Now added the call to
	  'TclWinFlushDirtyChannels' to this function. I don't know where
	  my head was last thursday (2001-09-06), but the call was
	  actually added to 'TclpObjChdir', i.e. the implementation of
	  [cd]. Corrected this now. Thanks to Vince Darley for spotting
	  this.

2001-09-10  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclProc.c:
	* tests/proc.test: made [proc] bytecompile a no-op for procs
	defined with _args_ as single argument and an empty body.
	[FQ 451441] 
	
2001-09-09  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in:
	* win/Makefile.in: Use () around variable name
	instead of {}. Use TCLTEST variable directly
	instead of depending on the tcltest alias.

2001-09-09  David Gravereaux <davygrvy@pobox.com>

	* generic/tcl.h:
	* generic/tclPlatDecls.h:  Reminder from David Cuthbert <dacut@kanga.org>
	that I hadn't finished the Borland compatibility stuff.
	[Patch: 436116]

2001-09-09  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/cmdAH.test: Modify cmdAH-20.5 and cmdAH-24.8
	to display the file atime or mtime results if
	the test fails.

2001-09-08  David Gravereaux <davygrvy@pobox.com>

	* win/mkd.bat:
	* win/rmd.bat: made these text files, text files again.
	[Patch: 451333]

2001-09-08  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/mkd.bat:
	* win/rmd.bat:
	Apply binary property (cvs admin -kb) to files and convert
	to CRLF linefeed format to fix the VC++ build. [Bug #219409]

2001-09-08 Vince Darley <vincentdarley@users.sourceforge.net>

	* generic/tclInt.h: 
	* generic/tclFCmd.c:
	* doc/FileSystem.3:
	* generic/tclIOUtil.c: removed Tcl_FSCopyFile fallback
	to channel copying, since the channels will not have
	access to interpreters and the channel copying currently
	requires an interp.  Code which required cross-platform
	copies always has interpreters, so that solves the problem.
	Fixes bug in TclKit.
	
2001-09-07  David Gravereaux <davygrvy@pobox.com>

	* win/tcl.m4: Added -link50compat option so a VC6 linker makes
	a VC5 (pre sp3) compatible import library.
	[Bug: 219257]

2001-09-07  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWinThrd.c (TclpThreadExit): Cast status argument to
	_endthreadex to unsigned instead of DWORD to match the Win32
	function prototype.

2001-09-06  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* All the changes below serve to fix bug [219148] which reports a
	  80x performance hit for file I/O on Win* systems. On my system
	  it was closer to a 120x hit. Problem report by Uwe Traum <no
	  email address available>.

	  The fix goes like this: The obstacle is 'FlushFileBuffers',
	  executed whenever Tcl writes data to the OS, as Tcl has to wait
	  for the disk to complete I/O, and disks are slow. We remove that
	  obstacle. This opens another problem, [file size] reports back
	  wrong numbers. So for [file size] we add the call back in. As
	  optimization we keep track of the channels which were written to
	  and flush only these.

	* win/tclWinFile.c (TclpObjStat): Added a call to
	  'TclWinFlushDirtyChannels'. This ensures that [file size] and
	  related commands report the correct size of a file even if Tcl
	  has recently written to it. Unixoid OS's always report the
	  correct size even for files with pending data, but Win*
	  syssystem don't. They only report what is actually on disk.

	* win/tclWinInt.h: Added declaration of
	  'TclWinFlushDirtyChannels', making it available to other parts
	  of the tcl core.

	* win/tclWinChan.c (TclWinFlushDirtyChannels): New, internal,
	  procedure. Goes through the list of open file channels and
	  forces the OS to flush its file buffers for all which were
	  written to since the last call of this function. This is an
	  expensive operation as Tcl has to wait for the OS to complete
	  actual writes to the disk.

	  (FileInfo): Added dirty flag required by the procedure above.

	  (FileOutputProc): Removed flushing of file buffers, setting the
	  dirty flag instead. This means that the previously incurred
	  delays do not happen anymore.

	  (TclWinOpenFileChannel): Added initialization of 'dirty' flag.

2001-09-06  Jeff Hobbs  <jeffh@ActiveState.com>

	* doc/http.n: noted -binary, charset and coding state keys.
	* tests/http.test:
	* library/http/pkgIndex.tcl:
	* library/http/http.tcl (geturl): correctly get charset parameter
	and convert text according to specified encoding (if known).  RFC
	iso8859-1 is used by default.  Also recognize Content-encoding to
	see if we should do binary translation.  Added a CYA -binary
	switch for the cases that were missed. [Bug #219211 #219399]

	* tests/ioUtil.test: changed to make better use of constraints and
	remove knownBug constraints that weren't valid.

2001-09-06  Don Porter  <dgp@users.sourceforge.net>

	* tests/unixInit.test (unixInit-3.2): Updated test to support
	  newer HP-UX releases that properly report euc-jp as the system
	  encoding for Japanese.  Bug report and patch verification by Bob
	  Techentin.  [Bug 453883]

	* doc/http.n:
	* library/http/*.tcl:
	* tools/tcl.wse.in:
	* tools/tclmin.wse:
	* unix/Makefile.in:
	* win/{Mm}akefile.*:  Updated http package to version 2.4,
	reflecting the new features just added.

2001-09-06 Vince Darley <vincentdarley@users.sourceforge.net>

	* generic/tclTest.c: tests of old-fs hooks no longer cause problems
	in threaded builds.  Also removed unused unload proc.
	* generic/tcl.decls:
	* generic/tclIOUtilc: added Tcl_FSMountsChanged so that a vfs
	can inform the filesystem that the filesystem epoch must be
	changed (since cached filesystems may now be incorrect).  Fixes
	problem running tclvfs extension.
	* library/tcltest/tcltest.tcl: if tests aren't in a native
	filesystem, then don't use pipes to run them. [Bug 458741]
	
2001-09-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tcl.decls (479 generic): 
	* generic/tclIO.c (Tcl_Seek,Tcl_Tell,Tcl_OutputBuffered): Added
	public function to return the size of the output buffer and
	reworked other channel functions to use this shared functionality
	and that of Tcl_InputBuffered() too. [TIP#49, Rolf Schroedter]

2001-09-05  David Gravereaux <davygrvy@pobox.com>

	* generic/tclPlatDecls.h:  Another small trim finalizing Borland
	support.

	* win/tclWinPipe.c:
	* win/tclWinPort.h:  More Borland compatibility fixes.  Changed
	EDQUOT #define from 49 to 69.  Borland had a clash as it was already
	using this number.  Upon advice from Helmut Giese, EDQUOT has been
	found in other header files #defined as 69.
	[Patch: 436116]

	* win/.cvsignore:  A few more glob patterns added.

	* win/makefile.bc (new):  Borland lives once more! rejoice..
	* generic/tclAlloc.c: Small Borland compatibility fix.
	* win/tclWinTime.c:  More Borland compatibility fixes.
	[Patch: 436116]

2001-09-05 Vince Darley <vincentdarley@users.sourceforge.net>

	* tests/winFCmd.test: made notWin2000 constraint false if not
	running on Windows at all.
	
2001-09-04  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinThrd.c:  Revisited _beginthreadex() stuff.  Instead
	of assuming a c-runtime implimentation of _beginthreadex normal,
	I reversed the logic to not assume, and use when is by explicitly
	needing to add runtimes that support it such as Borland.

	* generic/tcl.h:
	* generic/tclPlatDecls.h:  Borland compatibility change so
	ClientData was properly typed as a void* and TCHAR would not be
	defined twice.

	* generic/tcl.h:  Removed a small mistake from before.  Changes to
	the EXTERN macro for proper Borland compatibility will have to see
	a TIP.  What's this with the MS compiler:

		__declspec(dllexport) int func (int a, int b);

	will have to be this with Borland:

		int __cdecl __export func (int a, int b);

	The order of the attribute needs to be after the return type.

2001-09-04  Don Porter  <dgp@users.sourceforge.net>

	* compat/strtod.c (strtod):  Fixed failure to handle expressions
	like 3eq2 and failure to set errno on overflow.  [Bug 440894]

2001-09-04  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclProc.c:
	* tests/proc.test: made [proc] check that formal args have
	simple names [Bug: 458548] 

2001-09-04 Vince Darley <vincentdarley@users.sourceforge.net>

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

	* generic/tclCompile.c: fixed incorrect operands for INST_LIST
	[Bug: 458241] (David Cuthbert, dacut@users.sourceforge.net)

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

	* generic/tclExecute.c (TclExecuteByteCode): fixed missing comma
	in debug macro.

2001-09-03  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/ExprLongObj.3: Fixed error in documentation of argument type
	to Tcl_ExprObj [Bug: 457435]

2001-09-02  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinThrd.c:  Portability fix for Cygwin who's c-runtime,
	not surprisingly, doesn't have the MSVCRT specific _beginthreadex /
	_endthreadex pair.  This might have to be revisited for proper
	Borland, lcc32, Watcom and other support as well.
	[Patch: 444255]

	* win/tclWinThrd.c:  Moved FinalizeConditionEvent() proto to within
	the main #ifdef TCL_THREADS block to avoid mingw warning about it
	being there but unused.

	* win/makefile.vc:  Added -Zl (zee el) to tclStubLib.c compile line
	to make sure the tclstub84.lib static library is built without
	requiring a specific C-runtime library at link-time for the end-use
	developer.  It has been noted on c.l.t that this trips many first
	time users trying to make extensions.
	[Patch: 403533]

2001-08-31  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclInt.h: added TclCompileListCmd header
	* generic/tclBasic.c: added TclCompileListCmd compile proc
	* generic/tclCompCmds.c (TclCompileListCmd): function to compile
	the 'list' command at parse time.
	* generic/tclExecute.c (TclExecuteByteCode): definition of
	INST_LIST bytecode.

	* doc/StringObj.3: added words of warning to use Tcl_ResetResult
	with the Tcl_Append* functions.

	* tests/compile.test: added compile-11.* interp result checks
	* generic/tclUtil.c (TclGetIntForIndex): added Tcl_ResetResult
	before Tcl_AppendStringsToObj to prevent shared object crash when
	called from bcc instruction.  The Tcl_Append* calls that append to
	the result object that are invoked by bcc insts must remember to
	call Tcl_ResetResult because the bcc doesn't do this for us.
	[Bug #456892]

2001-08-30  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclIndexObj.c: fixed some casting problems that upset
	Crays. [Bug #419528] (andreasen)

2001-08-30  Don Porter  <dgp@users.sourceforge.net>

	* generic/tcl.h: Silence warning from Sun compiler. [Bug 454374]

2001-08-30  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: allow cached fully-qualified command names
	to be usable from different namespaces within the same interpreter
	without forcing a new lookup. This speeds up scripts that pass
	command names in variables ("this" in some OO packages).
	[Patch 456668]. 

2001-08-30 Vince Darley <vincentdarley@users.sourceforge.net>

	Further fs updates.  After examining the most common Tcl
	extensions (TclX, BLT, Tk, TclPro, Mktclapp), it has been
	determined that only TclpGetCwd and the Access/Stat/Open
	insert/delete hooks of the internal fs functions are ever used.
	The remaining functions from Tcl's internal interfaces have
	therefore been removed, since Tcl now exports a more suitable
	public API (Tcl_FS...)
	
	* generic/tclInt.stubs:
	* generic/tclInt.h: updated for removed internal functions.
	Some new internal functions have been put in tclInt.h (and
	not exported in the stub table because good public equivalents
	exist).
	* generic/tclTest.c: some test functions used the internal private 
	APIs.  These tests have been retained, but modified to use 
	public APIs.  Also objectified the internal filesystem tests.
	* win/tclWinFile.c: removed TclpStat, TclpAccess and refactored
	code to use NativeAccess, NativeStat.  This should speed up
	stat, access and glob commands.
	* win/tclWinFCmd.c: removed all TclpCopy/Rename/Delete 
	File/Directory string-based procedures which aren't used any more.
	Improved efficiency of some other procedures. Ensure that filename
	conversions with a NULL interp do not crash Tcl.
	* mac/tclMacFCmd.c: wrapped long lines and cleaned up
	TclpObjNormalizePath, removed all TclpCopy/Rename/Delete 
	File/Directory string-based procedures which aren't used any more.
	* mac/tclMacFile.c: removed obsolete TclpStat, TclpAccess, TclpChdir,
	etc.
	* unix/tclUnixFCmd.c: removed use of TclpAccess, removed all
	TclpCopy/Rename/Delete File/Directory string-based procedures which
	aren't used any more.
	* unix/tclUnixFile.c: removed obsolete TclpStat, TclpAccess, TclpChdir,
	etc.
	* tcl(Unix|Mac|Win)Chan.c: objectified TclpOpenFileChannel.
	* various 'load' implementations all objectified.
	* generic/tclFileName.c: removed redundant code.
	* generic/tclIOUtil.c: removed TclStat, TclAccess, TclpListVolumes.
	Fix to MatchInDirectory at the root of a volume.  Also improved
	some documentation, and improved default path joining behaviour
	for virtual filesystems, especially regarding '~'.
	* tests/fileName.test: added tests to check for bugs fixed above.
	* doc/FileName.3: improved documentation
	
2001-08-30  David Gravereaux <davygrvy@pobox.com>

	* generic/tclAsync.c:
	* generic/tclEvent.c:
	* generic/tclInt.h: Improper cleanup of asyncMutex in tclAsync.c
	repaired.  TclFinalizeSynchronization() was trying to remove a
	registered mutex that was dumped earlier when the TSD it was stored
	in was cleared. This was only surfacing on *nix.  Windows was being
	masked by mutexes not actually being returned to the system!  That
	was repaired in a previous patch.  Needed to add a private
	TclFinalizeAsync() to tclAsync.c and called from Tcl_FinalizeThread().
	Pheww..  Is this done yet?
	[Bug: 414419] requested by Rob Ratcliff <rrr6399@futuretek.com>

2001-08-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCompCmds.c (TclPushVarName): noted 'static' defn.
	[Bug #453872]

2001-08-26  Don Porter <dgp@users.sourceforge.net>

	* library/auto.tcl (tcl_findLibrary):
	* tests/unixInit.test (unixInit-2.{1,9}):
	* unix/tclUnixInit.c (TclpInitLibraryPath):
	* win/tclWinInit.c (TclpInitLibraryPath):  Corrected 
	inconsistency between  the search path for script libraries and
	the directory name $DISTNAME into which distributions built
	by 'make test' unpack.  [Bug 455642]

2001-08-24  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/stringComp.test: added string-1.3
	* generic/tclCompCmds.c (TclCompileStringCmd): changed to return
	TCL_OUT_LINE_COMPILE instead of TCL_ERROR when compiling and an
	unknown string method is called.  This is necessary as the string
	command may be never called, or not until 'string' is redefined.

2001-08-24 Vince Darley <vincentdarley@users.sourceforge.net>

	* doc/glob.n: documented windows-style path issue with glob.
	[Bug: 219392]
	* doc/filename.n: documented windows path/file length limitation.
	[Bug: 454597]

2001-08-24  Don Porter <dgp@users.sourceforge.net>

	* tests/unixInit.test (unixInit-2.9): Corrected expected result
	to match Tcl's quirky construction of its init library path.

2001-08-23  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* win/tclWinPipe.c (BuildCommandLine): Fixed tcl Bug
	  [432499]. Part of the code used the non-absolute path to the
	  executable to determine quoting. This failed if the absolute
	  path cotained spaces, but the application name itselfl not. This
	  bug caused no trouble on Win NT 5, but does for other variants
	  in the Win* family. Report and fix due to Ken Poole
	  <kenpoole@users.sourceforge.net>.

	* unix/configure:
	* unix/tcl.m4: added QNX-6 build support. [Bug #219410] (loverso)

	* unix/tclUnixFCmd.c:
	* generic/tclIOUtil.c:
	* generic/tclFileName.c: corrected minor compiler warnings.

2001-08-23 Vince Darley <vincentdarley@users.sourceforge.net>

	Variety of small filesystem and vfs issues fixed or improved.
	The new fs code allows many new opportunities for efficiency
	improvements through the objectified API. The main changes
	integrated here are such efficiency improvements.  Some
	limitations of the original implementation have also now been
	lifted.  Meanwhile a variety of fs bugs (some old, some new)
	have also been fixed.
	
	* generic/tclFileName.c: Made Tcl_FSSplitPath more efficient, 
	and removed some static string-based procedures which are no 
	longer used.  Much more objectification.  Tcl_FSJoinPath
	is now very efficient and more aware of virtual filesystems.
	Clarified where the Mac-specific code attempts to interpret
	Unix-style paths.  Modified TclDoGlob to use lstat not
	access to fix [Bug: 434876, L. Virden]
	* tcl(Win|Unix|Mac)FCmd.c:
	* tcl(Win|Unix|Mac)File.c: replaced TclpListVolumes with
	TclpObjListVolumes with different signature, updated code due
	to more efficient signature of Tcl_FSGetTranslatedPath.  Used
	cached native paths where possible to improve efficiency --
	this was completed on MacOS, but on Unix and Win the traversal
	functions make the task much more complex, so there are still
	some improvements possible there.  Removed unused 
	TclpNormalizePath which had been left in tclWinFCmd.c.
	Objectified all 'file attributes' functions.  Fixed the new
	[Bug:451571, Bruce Stephens] which is most obvious on Unix, 
	but could occur on MacOS or Windows.  This bug actually existed
	in Tcl 8.3.x but was only made obvious by the recent filesystem
	overhaul when the code was exercised more heavily.  
	* tests/fileName.test: Three new tests to exercise the above bug,
	and make sure it is fixed correctly.
	* unix/tclUnixFile.c: avoid panic in glob when a link
	doesn't point anywhere.  It would probably be good to define
	exactly what Tcl should do in circumstances like these, and
	make sure mac/win/unix all behave accordingly. [Bug: 417111, 
	Hemang Lavana]. Also fixed misleading/obsolete comment in the code.
	* generic/tcl.stubs: changed signature of Tcl_FSGetTranslatedPath
	and added Tcl_FSGetTranslatedStringPath.
	These changes allow further optimisations in the FS code.
	* generic/tcl.h: changed signature of Tcl_FSListVolumes so that 
	it doesn't require a Tcl interpreter plus result.  Renamed 
	Tcl_FSReadLink to Tcl_FSLink with additional argument so
	we can support making links in the future. [Patch: 450340]
	* generic/tclInt.h:
	added declaration for TclpObjListVolumes.  Objectified 
	internal call signatures for 'file attributes' functions, and
	added an internal objectified get path type function.
	* generic/tclIOUtil.c: added the moved function TclpListVolumes 
	which calls platform specific code (needed for backwards 
	compatibility), and improved efficiency of parts of the FS
	(particularly file normalization).  Much less copying and
	memory allocation is required now.  added new GetPathType 
	so that changes in 'file volumes' can actually affect files'
	types, and objectified more code.  Made current code work
	with test suite artificially changing current platform.
	Added 'static' keywords where required.
	* generic/tclIO.c:
	* generic/tclTest.c: Added 'static' keywords, fixing 
	[Bug: 453872, Bob Techentin]
	* generic/tclCmdAH.c: file command implementation updated for 
	API changes, removed unnecessary special-case SplitPath static
	function, since it no longer helps prevent code duplication.
	Moved setting of interpreter result to each individual location
	that actually required it, to avoid very large code separation
	between reading and setting the result.
	* doc/FileSystem.3: updated documentation for the new or 
	changed APIs, and clarified some issues.
	* doc/SplitPath.3: added pointer to newer APIs in FileSystem.3
	* doc/filename.n: clarified current implementation of tilde
	support on Mac/Win.  [Bug:453514, Sergey Kuzmin]
	* doc/glob.n: improved documentation for '-directory' and '-path' 
	options.
	
	There are now many private, obsolete, platform-specific 'Tclp' 
	string-based filesystem APIs which could be removed.  We should
	check whether any of these are used by extensions and, at least
	in Tcl 9, remove them.
	
	The above changes signify a ***POTENTIAL INCOMPATIBILITY*** 
	with 8.4a3, since signatures of two functions in the new API 
	have changed, but not with older versions of Tcl.

2001-08-23  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclBinary.c (FormatNumber): Extract a long from the
	object and not an int, to stop [binary format] from being unable
	to format some input numbers on architectures where sizeof(int) is
	less than sizeof(long) (particularly Alpha.)  [tiprender Bug #441861]

	* tests/format.test: Converted conditional execution of tests into
	a test constraint.

2001-08-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/Makefile.in:
	* win/makefile.vc: updated install target for dde1.2
	* doc/dde.n: fixed dde man page (which was totally incorrect).
	* tests/winDde.test:
	* win/tclWinDde.c (Tcl_DdeObjCmd): added -binary option to dde
	request command to allow for returning binary data. [Bug #227482]
	Updated dde to 1.2

	* tests/tcltest.test: added unixExecs constraint to files that
	used 'grep' in the test. [Bug #453143]

	* library/tcltest/tcltest.tcl: fixed stdio constraint test.
	[Patch #454050] (stanton)
	Simplified unixExecs constriant test. 
	
2001-08-22  Don Porter <dgp@users.sourceforge.net>

	* tests/ioUtil.test (ioUtil-3.*): Corrected errors in tests
	revealed by fix of overagressive compiler.  [Bug 451200]

2001-08-21  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompCmds.c:
	* tests/compile.test: Fixed overagressive compilation of [catch]:
	it was catching errors at substitution time. [Bug #219184]
	
2001-08-21  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/tcltest.test (tcltest-12.2): fixed test that would break
	when env vars weren't Tcl list friendly [Patch #454046] (stanton)

2001-08-20  Jeff Hobbs  <jeffh@ActiveState.com>

	* library/http/http.tcl (geturl): added port number to Host:
	header to comply with HTTP/1.1 spec (RFC 2068).  [Bug #452217]

2001-08-16  David Gravereaux <davygrvy@pobox.com>

	* tools/tcl.wse.in:
	* tools/tcl.hpj.in:
	* win/tcl.hpj.in:  Removed -kb storage in CVS to ensure these text
	files are checked-out in the translation mode CVS is in.  Setting
	these as binary as part of an effort to make sure they are always
	in CRLF, no matter what the CVS translation, is bypassing how CVS
	works and is confusing.

	* tools/genStubs.tcl:  Removed LF-only output.  Having to reconvert
	back to CRLF before committing to CVS was giving me a headache.
	[Bug: 451333]

	* win/makefile.vc: replaced $(WINDIR) with $(include32) for the
	.rc.res inference rule.  winver.h wasn't getting included.
	[Bug: 445630]

2001-08-14  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c: make the intial maxNestingDepth of an
	interpreter be MAX_NESTING_DEPTH instead of a hardwired value
	[Bug: 232564]

2001-08-13  Miguel Sofer  <msofer@users.sourceforge.net>

	* tests/trace.test: Corrected test numbers [Bug: 449794] 

2001-08-12  Mo DeJong  <mdejong@redhat.com>

	* unix/configure: Regen.
	* unix/configure.in:
	* unix/tcl.m4: Use GCC variable set by AC_PROG_CC instead
	of defining our own using_gcc variable.

2001-08-11  Vince Darley <vincentdarley@users.sourceforge.net>

        Variety of small issues introduced by the vfs code fixed:
	* generic/tclIOUtil.c: uninitialised read.
	* generic/tclFCmd.c: possible memory leak in file delete 
	with error condition.

2001-08-10  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclVar.c: 
	* tests/trace.test: Insure that [array] traces work correctly for
	undefined variables [Bug: 449094] 

2001-08-09  Mo DeJong  <mdejong@redhat.com>

	* unix/Makefile.in: Delete the unused getcwd.o
	target. This fixes bug #440942.

	mean there will be an 8.4a4 release.  [Bug 448938].

2001-08-06  Jeff Hobbs  <jeffh@ActiveState.com>

	8.4a3 RELEASE

	* changes:
	* README:
	* mac/README: 
	* unix/README:
	* win/README.binary: updated for 8.4a3 release

	* generic/tclFileName.c (Tcl_FSSplitPath): update to Tcl style
	guide.

	* generic/tclFCmd.c (FileCopyRename): fixed mem leak in
	introduction of vfs code where a new Tcl_Obj wasn't freed.

	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd, Tcl_RegsubObjCmd):
	reordered the retrieval of arguments to avoid shimmering bug when
	the pattern and string referenced the same object.

	* unix/configure: regenerated
	* unix/tcl.m4: added GNU (HURD) configuration target. (brinkmann)
	[Patch: #442974]

	* win/README: made note of URL for Windows compilation notes

	* win/tclWinThrd.c (TclpFinalizeMutex, TclpFinalizeCondition):
	added DeleteCriticalSection calls for cleanup [Patch: #419683]

	* unix/tclUnixPipe.c (TclpCreateTempFile): fixed use of tmpnam,
	which is dangerous. [Patch: #442636] (lim)
	The use of tmpnam in TclpTempFileName must still be changed.

	* tests/http.test (http-4.14): fixed variable error return.
	[Bug: 424252]

2001-08-03  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/configure: regenerated
	* win/tcl.m4: fixed DLLSUFFIX definition to always be ${DBGX}.dll.
	This is necessary for TEA compliant builds that build shared
	against a static-built Tcl.
	* win/Makefile.in ($(TCLSH)): added $(TCL_STUB_LIB_FILE) to build
	target, otherwise it wouldn't get generated in a static build.

2001-08-06  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* generic/tclIOCmd.c (Tcl_GetsObjCmd): Applied patch from SF item
	  [442665] to fix the bug reported by it. The function can corrupt
	  a freed object if it is called with objc == 3. This is because
	  it retrieves resultPtr and does not increment its reference
	  count, but then calls Tcl_ObjSetVar2, which causes the retrieved
	  resultPtr object to be released.
	
2001-08-06  Don Porter <dgp@users.sourceforge.net>

	* doc/tclsh.1:  Added note that the tclsh program is frequently
	installed with the Tcl version numer as part of the name.
	[Patch 402725]

	* generic/tclPkg.c:
	* tests/pkg.test:  [package forget] now forgets all of the
	package arguments it receives, not stopping when a package is
	not found.  [Bug 415273]

2001-08-02  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclIOUtil.c (Tcl_FSMatchInDirectory): corrected
	uninitialized value.

2001-08-02  Mo DeJong  <mdejong@redhat.com>

	* generic/tclPlatDecls.h:
	* win/tclWinPort.h:
	Revert <tchar.h> related changes made to improve
	Cygwin support on 2001-07-18. This change ended
	up breaking the VC++ build because of conflicts
	between Windows APIs and internal Tk APIs.

2001-08-01  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixFCmd.c: minor casts to eliminate warnings. (lim)
	[Patch: #440218]

	* tests/parseOld.test: changed some tests that required
	testwordend to exist to skip in a proper tcltest manner.
	[Bug: #442663]

	* library/http/http.tcl (http::mapReply): the regsub'ing of \n and
	\t to escape them was unnecessary.

2001-07-24  Mo DeJong  <mdejong@redhat.com>

	* win/tclWinThrd.c (Tcl_CreateThread): Close Windows
	HANDLE returned by _beginthreadex. The MS documentation
	states that this handle is not closed by a later call to
	_endthreadex.

2001-07-21  Don Porter  <dgp@users.sourceforge.net>

	* doc/pkgMkindex.n:
	* library/package.tcl:  Corrected documentation and usage
	message of [pkg_mkIndex].

2001-07-18  Mo DeJong  <mdejong@redhat.com>

	* generic/tclPlatDecls.h: Define TCHAR by including
	windows.h instead of tchar.h since Cygwin does not
	support the tchar.h header. Include CHECK_UNICODE_CALLS
	logic from tclWinPort.h.
	* win/tclWinPort.h: Remove CHECK_UNICODE_CALLS logic.
	Remove include of windows.h since this now done it
	tclPlatDecls.h.
	* win/tclWinReg.c: Remove duplicate include of windows.h.

2001-07-18  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* generic/tclIO.c: Aftermath to [SF #427196]. Squash empty buffers
	  if they are smaller than the requested buffersize, to prevent
	  reusage of old buffers and to honor changes in the requested
	  buffersize made by the user.

2001-07-17  Mo DeJong  <mdejong@redhat.com>

	* win/tclWinFile.c (TclpReadlink): Add Cygwin specific definition
	for the TclpReadlink function. This method implements reading of
	symbolic links when build with Cygwin.

2001-07-17  Mo DeJong  <mdejong@redhat.com>

	* win/tclWinPort.h: Add Cygwin specific defines for environ
	and timezone variables.

2001-07-17  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* generic/tclIO.c (GetInput): Fixed [SF #427196]. Memory was
	  overwritten because a buffer was used after a change of the
	  requested buffersize together with that requested buffersize and
	  not its actual size, which was smaller. Note that the continous
	  reuse of the smaller buffer negatively impacts performance. The
	  system never allocates a buffer with the newly requested bigger
	  buffersize.

2001-07-16  Mo DeJong  <mdejong@redhat.com>

	* generic/tcl.h: Define __WIN32__ when
	__CYGWIN__ or __MINGW32__ is defined.
	* generic/tclAlloc.c: Define caddr_t when
	compiling with VC++ or mingw. This type is
	already defined when compiling with Cygwin.

2001-07-16  Mo DeJong  <mdejong@redhat.com>

	* win/tclWinConsole.c:
	* win/tclWinPipe.c:
	* win/tclWinPort.h:
	* win/tclWinSerial.c:
	* win/tclWinThrd.c:
	Remove unnecessary #includes of dos.h, direct.h,
	and tchar.h. This will help the Cygwin porting
	effort since these headers do not exist under Cygwin.

2001-07-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinPipe.c (PipeClose2Proc): constrained the mutex lock to
	just the TerminateThread call and waiting for termination. (jsmith)

	* generic/tclCmdMZ.c: Removed extra copy of the SCAN_* macros
	#defined in generic/tclScan.c. (porter) [Bug 441230]

2001-07-12  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/unixInit.test (unixInit-2.8): Added extra constraint,
	notInstalledInTmp, to stop this test from damaging installations
	in /tmp; not much fun to have to reinstall the Tcl library every
	time you run the test suite!

	* tests/subst.test (subst-10.*): Updated tests to check new
	behaviour for 'break' in command substitutions.
	(subst-1.2,subst-7.1): Error messages changed.
	* doc/SubstObj.3: New file, to document Tcl_SubstObj.
	* doc/subst.n: Improved and updated documentation for 'subst' to
	help support the changed behaviour.
	* generic/tcl.decls (generic-437): Declaration for Tcl_SubstObj
	* generic/tcl.h (TCL_SUBST_*): Added flags for Tcl_SubstObj.
	* generic/tclCmdMZ.c (Tcl_SubstObj,Tcl_SubstObjCmd): Divided into
	two parts to allow people to access the innards of 'subst' and
	changed the behaviour when command substitutions do a 'break' to
	be different from 'continue'.  Also now works with objects, which
	allows for some nifty optimisations with variable substitutions
	and a slight improvement with command substitutions.  [TIP#36]

2001-07-10  Mo DeJong  <mdejong@redhat.com>

	* unix/Makefile.in: Add AR variable for use in STLIB_LD.
	* unix/configure: Regen.
	* unix/configure.in: Use STLIB_LD when defining MAKE_LIB
	and MAKE_STUB_LIB. Subst RANLIB and AR.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Add doc comment about
	STLIB_LD command. Check ${AR} env var when setting
	STLIB_LD and delay evaluation until make time.
	* win/configure: Regen.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Delay evaluation of
	${AR} in STLIB_LD and add flags to better match the
	Unix implementation. Don't bother defining AR when
	using VC++ since it is not used.

2001-07-06  Mo DeJong  <mdejong@redhat.com>

	* win/configure: Regen.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Pass -e _WinMain@16 in
	addition to the -mwindows flag to work around a problem
	with ld when it incorrectly use main() as the executable
	entry point when both WinMain() and main() are available.

2001-07-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/cmdAH.test: Added leading zero to file modes to work
	around fault in HPUX strtol() which ignores the base parameter
	[Bug #438808]

2001-07-05  Mo DeJong  <mdejong@redhat.com>

	* win/Makefile.in: Subst DEPARG directly instead
	of relying on a variable. This will make Cygwin
	builds faster since an extra exec will be avoided.
	* win/configure: Regen.
	* win/configure.in: Subst DEPARG.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Move AC_MSG_CHECKING
	after the AC_CHECK_PROG so that status messages do
	not get mixed together. Set DEPARG based on the
	results of the cygpath check so that we avoid using
	an extra exec when it is not needed. Use ac_cv_cygwin
	status flag instead of looking at the output of
	gcc -v, which works in the case where -mno-cygwin is
	set in the CFLAGS.

2001-07-04  Jeff Hobbs  <jeffh@ActiveState.com>

	* README:
	* mac/README:
	* unix/README:
	* win/README:
	* win/README.binary: updated READMEs with purls

2001-07-03  Mo DeJong  <mdejong@redhat.com>

	* win/Makefile.in: Remove PATHTYPE variable.
	* win/configure: Regen.
	* win/configure.in: Don't subst PATHTYPE.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Remove PATHTYPE
	variable. Set CYGPATH to "cygpath -w" if the
	cygpath executable is found on the path. This
	approach works for native Cygwin builds and
	cross compiles.

2001-07-03  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/var.test:
	* generic/tclVar.c (Tcl_VariableObjCmd): added patch to check for
	number of args. [Patch #426038]

	* generic/tclVar.c (Tcl_GetVar2Ex): added ability to recognize
	TCL_TRACE_READS flags to cause creation of part1 in TclLookupVar
	to make sure newly created array will get read traces triggered
	appropriately.  This is called by Tcl_ObjGetVar2, Tcl_GetVar, and
	Tcl_GetVar2.
	(TclSetIndexedScalar, TclSetElementOfIndexedArray): added read
	trace triggering for lappend case.
	(Tcl_LappendObjCmd): pass TCL_TRACE_READS to Tcl_ObjGetVar2 to
	trigger possible read traces for new arrays.

	* generic/tclExecute.c (TclExecuteByteCode): added TCL_TRACE_READS
	flag to INST_LAPPEND(_ARRAY)_STK case to trigger read traces for
	newly created arrays.  Removed unnecessary #ifdef for
	TCL_COMPILE_DEBUG in INST_LOAD_SCALAR1 case.

	* tests/append.test:
	* tests/appendComp.test: added tests for read trace triggering for
	append and lappend.

2001-07-03  Mo DeJong  <mdejong@redhat.com>

	* tests/clock.test (clock-2.5): Adjust test so that it passes
	when the time slice is 60 msecs, now passes under Windows 98.

2001-07-03  Mo DeJong  <mdejong@redhat.com>

	* win/tcl.m4 (SC_CONFIG_CFLAGS): Don't pass the v flag
	to ${AR} when using gcc, verbose output is not needed.

2001-07-03  Don Porter  <dgp@users.sourceforge.net>

	* tests/unixInit.test (unixInit-2.8):  Changed test back to using
	installation layout, adding comments explaining why the test writes
	to the directories it does, and checks to avoid destroying other
	files in /tmp.

2001-07-03  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/unixInit.test (unixInit-1.2): Fixed faults reported in
	Bug#438070 - well, at least enough to work on Solaris - and added
	comments that should make what is going on in the test clearer.

2001-07-02  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/util.test: added util-4.6
	* generic/tclUtil.c (Tcl_ConcatObj): Corrected walking backwards
	over utf-8 chars. [Bug #227512]

2001-07-02  Don Porter  <dgp@users.sourceforge.net>

	* tests/unixInit.test (unixInit-2.8):  Corrected test for all
	absolute pathnames in library path when executable is installed
	near root directory to use correct development directory layout.
	[Bug 438014]

	* tests/unixInit.test (unixInit-2.9):  
	* unix/tclUnixInit.c (TclpInitLibraryPath):
	* win/tclWinInit.c (TclpInitLibraryPath):  Corrected buggy
	construction of search path entries relative to executable.
	Added test for bad construction.  [Bug 438014]

2001-06-28  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclNamesp.c: Correction to faulty patch from [Bug: 231259] 

2001-06-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/unixInit.test (unixInit-1.2): Modified so as not to
	require a local echo service, which fails on many systems which
	have that turned off for security reasons...

2001-06-27  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclInt.h:
	* generic/tclObj.c:
	* unix/Makefile.in: added a -DPURIFY mode that makes Tcl_Obj's
	allocated and free singularly (instead of in alloc in blocks and
	never free) to allow checkers like Purify to operate better.

	* library/encoding/koi8-u.enc: added koi8-u (Ukranian variant)
	encoding.

	* tests/subst.test:
	* generic/tclUtf.c (Tcl_UtfBackslash): Corrected backslash
	handling of multibyte utf-8 chars. [Bug #217987]

	* generic/tclCmdIL.c (InfoProcsCmd): fixed potential mem leak in
	info procs that created objects without using them.

	* generic/tclCompCmds.c (TclCompileStringCmd): fixed mem leak when
	string command failed to parse the subcommand.

	* doc/interp.n:
	* doc/unknown.n: updated notes about what is in a safe interp.
	[Bug #218605]

2001-06-27  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/event.test (event-11.5): Removed hard-coded port number
	which could fail on some systems.  [Bug #436727]

2001-06-26  Mo DeJong  <mdejong@redhat.com>

	* unix/Makefile.in:
	* win/Makefile.in: Add `make shell` target. This target
	will set the proper env vars before invoking tclsh
	from the build directory.

2001-06-26  Mo DeJong  <mdejong@redhat.com>

	* win/Makefile.in: Use : to separate VPATH entries. This
	works for both Cygwin builds and cross builds, the VPSEP
	variable is simply unneeded complexity.
	* win/configure: Regen.
	* win/configure.in: Don't subst VPSEP.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Remove VPSEP variable.

2001-06-26  Mo DeJong  <mdejong@redhat.com>

	* unix/configure: Regen.
	* unix/configure.in: Fix last checkin by removing
	export since that only works in bash.
	* win/configure: Regen.
	* win/configure.in: Ditto.

2001-06-26  Mo DeJong  <mdejong@redhat.com>

	* unix/configure: Regen.
	* unix/configure.in: Set CFLAGS to "" if the user
	did not set CFLAGS in the env. This keeps AC_PROG_CC
	from adding "-g -O2" to the CFLAGS by default.
	* win/configure: Regen.
	* win/configure.in: Ditto.

2001-06-25  Mo DeJong  <mdejong@redhat.com>

	* win/configure: Regen.
	* win/configure.in: Use RC_DEFINE flag from tcl.m4.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Set RC_DEFINE
	flag based on the compiler in use.
	
2001-06-25  Mo DeJong  <mdejong@redhat.com>

	* win/tcl.m4 (SC_CONFIG_CFLAGS): Link to the
	imm32 library when building with mingw gcc.

2001-06-25  Mo DeJong  <mdejong@redhat.com>

	* win/configure: Regen.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): When building with
	gcc, don't attempt to link with LD or support dllwrap.
	Simply require a recent version of Cygwin gcc or Mingw
	gcc that supports -shared. When linking, use gcc instead
	of ld since gcc automatically includes libs like -lmsvcrt.

2001-06-22  Mo DeJong  <mdejong@redhat.com>

	* win/configure: Regen.
	* win/configure.in: Add resource compiler fix from
	8.3.3 to fix compiling with mingw.

2001-06-22  Mo DeJong  <mdejong@redhat.com>

	* win/configure: Regen.
	* win/tcl.m4: Fix silly typo in last checkin.

2001-06-22  Mo DeJong  <mdejong@redhat.com>

	* unix/Makefile.in: Set CFLAGS to @CFLAGS@ and @CFLAGS_DEFAULT@.
	Set LDFLAGS to @LDFLAGS@ and @LDFLAGS_DEFAULT@. Add LDFLAGS_DEBUG
	and LDFLAGS_OPTIMIZE to match the way CFLAGS_DEFAULT works.
 	This will support user set CFLAGS or LDFLAGS at configure time.
	* unix/configure: Regen.
	* unix/configure.in: Don't set CFLAGS to CFLAGS_DEFAULT, instead
	subst CFLAGS_DEFAULT into the Makefile. Add AC_SUBST for CFLAGS_DEFAULT,
	LDFLAGS_DEFAULT, LDFLAGS_DEBUG, and LDFLAGS_OPTIMIZE.
	* unix/tcl.m4 (SC_ENABLE_SYMBOLS): Modify LDFLAGS_DEFAULT so that
	it uses a Makefile variable just like CFLAGS_DEFAULT.
	* win/Makefile.in: Set CFLAGS to @CFLAGS@ and @CFLAGS_DEFAULT@.
	Set LDFLAGS to @LDFLAGS@ and @LDFLAGS_DEFAULT@.
	This will support user set CFLAGS or LDFLAGS at configure time.
	* win/configure: Regen.
	* win/configure.in: Don't set CFLAGS or LDFLAGS, instead subst
	CFLAGS_DEFAULT and LDFLAGS_DEFAULT into the Makefile.
	* win/tcl.m4 (SC_ENABLE_SYMBOLS): Modify LDFLAGS_DEFAULT so that
	it uses a Makefile variable just like CFLAGS_DEFAULT.

2001-06-22  Mo DeJong  <mdejong@redhat.com>

	* win/configure:
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Don't set LDFLAGS_DEBUG
	to -g or LDFLAGS_OPTIMIZE to -O when compiling with gcc.
	These flags are not needed and can cause problems with
	the Cygwin version of ld.

2001-06-18  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/unixInit.test (unixInit-1.2,unixInit-2.8): Added test for
	code described below, and fixed a couple of errors that caused
	problems during testing; the code to determine the installedTcl
	constraint was wrong, and test unixInit-2.8 assumed that /tmp/lib
	was free for use and could be deleted, which clashed nastily with
	my installation and made other tests fail unnecessarily!

	* unix/tclUnixChan.c (TtyInit,TclpOpenFileChannel,
	Tcl_MakeFileChannel,TclpGetDefaultStdChannel): Alterations so that
	the standard channels - stdin, stdout and stderr - have the
	correct type and fconfigure options.  This required making the
	initialisation of serial lines a little more sophisticated to
	make the console behave correctly in interactive mode... [Bug
	#219137 and duplicates]

2001-06-16  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.decls:
	* generic/tclInt.h: 
	* generic/tclPanic.c (Tcl_PanicVA):
	* mac/tclMacAppInit.c (main):
	* mac/tclMacPanic.c (TclpPanic):
	* unix/tclUnixPort.h:
	* win/tclWinPort.h: Replaced TclMacSetPanic with TclpPanic
	for setting a platform-specific panic handler.  TclpPanic
	is NULL on Unix and Windows.  Fixes broken wish on Mac due
	to earlier patches.  [Patch 415648]
	
	* generic/tclIntPlatDecls.h:
	* generic/tclStubInit.c: `make gentubs` after above changes.

2001-06-13  Don Porter  <dgp@users.sourceforge.net>

	* mac/tclMacAppInit.c (main, Macintosh_Init):
	* mac/tclMacBOAAppInit.c (main):
	* mac/tclMacPanic.c: Applied patches from Dan Steffen correcting
	problems on the Macintosh in the 2001-06-08 changes.

2001-06-12  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/regexp.test (regexp-18.12): 
	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd): Fixed so that submatches
	that do not match always have index pair {-1 -1} [Bug #219232]

2001-06-08  Don Porter  <dgp@users.sourceforge.net>

	* generic/tcl.h:
	* generic/tcl.decls:
	* generic/tclPanic.c: Added CONST to Tcl_*Panic* public interfaces.
	[Patch 415648, TIP 27]

	* generic/tclInt.decls:
	* mac/tclMacAppInit.c (main):
	* mac/tclMacBOAAppInit.c (main):
	* mac/tclMacPanic.c: Modified special Mac implementations of
	Tcl_*Panic* to be exact copies of the generic implementations.
	Added TclMacSetPanic.  The generic implementations should be
	used directly, rather than copies, but that requires further
	changes by someone familiar with the Mac build systems.
	[Patch 415648]

	* generic/tclDecls.h:
	* generic/tclIntPlatDecls.h:
	* generic/tclStubInit.c: `make gentubs` after above changes.

	* doc/Panic.3:
	* unix/mkLinks:  New file documenting Tcl_*Panic* public interfaces,
	followed by `make mklinks`.  [Patch 415648, Bug 219170, Bug 414936]

2001-06-03  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclUtil.c (Tcl_DStringAppendElement): patch to save an
	extra strlen call.  [Bug #428572]

2001-05-30  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): Added two casts to
	INST_STR_CMP implementation to get rid of a couple warnings from
	the SUNWspro C compiler.

	* generic/tclBasic.c (Tcl_GetMathFuncInfo,Tcl_ListMathFuncs): 
	* generic/tclCmdIL.c (Tcl_InfoObjCmd,InfoFunctionsCmd): 
	* generic/tcl.decls (generic table, positions 435+436): 
	* tests/info.test: 
	* doc/CrtMathFnc.3: 
	* doc/info.n: Changes due to TIP #15 "Functions to List and Detail
	Math Functions"

2001-05-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* library/init.tcl (unknown): removed errant " in error message

2001-05-27  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/regc_locale.c: updated character class range data for
	Unicode v3.1.0 compliance.
	* generic/tclUniData.c: regenerated from Unicode v3.1.0 data file
	(new as of 2001-05-16).  This brings Tcl to current unicode
	compliance.

	* tests/utf.test: added tests to check unicode 3 compliance

	* unix/Makefile.in (tclUtf.o): added tclUniData.c dependency.

	* tools/uniClass.tcl: added comments to output format and the
	script for clarification.

	* tools/uniParse.tcl: corrected filename output and GetDelta macro
	to use 'info' as param (was 'infO')

2001-05-26  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclVar.c (tclArraySearchType,SetArraySearchObj,
	ParseSearchId): Added code to speed up array searching by reducing
	the amount of parsing needed for searchIds.

	* generic/tclObj.c (TclInitObjSubsystem): 
	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): 
	* generic/tclNamesp.c (TclInitNamespaceSubsystem): 
	* generic/tclInt.h: Moved some Tcl_ObjType initialisation to
	TclInitObjSubsystem to be with the bulk of the rest.
	[Patch 424851] Committed by Miguel Sofer <mig@utdt.edu>

2001-05-23  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/io.test: changed io-52.[9-11] to not be platform sensitive
	with EOL translation.

	based on http://www.unicode.org/Public/MAPPINGS/. (kuhn)

2001-05-23  Mo DeJong  <mdejong@redhat.com>

	* unix/tcl.m4 (SC_PATH_TCLCONFIG): Fix comments,
	and typo in cached variable name.

2001-05-23  Mo DeJong  <mdejong@redhat.com>

	* unix/tcl.m4 (SC_LOAD_TKCONFIG):
	Remove use of undefined TCLCONFIG variable and
	call AC_MSG_RESULT to print the checking result.
	* win/tcl.m4: Ditto.

2001-05-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclObj.c (TclAllocateFreeObjects): simplified
	objSizePlusPadding to use sizeof(Tcl_Obj) (max)
	Corrected use of tclObjsAlloced/Freed/Shared in TCL_MEM_DEBUG
	compile.

2001-05-22  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: removed Tcl_DuplicateObj in INST_DUP 

2001-05-21  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/tcltest.test (tcltest-19.1): fixed failing test that was
	getting affected by Windows env handling of empty valued elements.

	* unix/tcl.m4: added more common install directories in which to
	search for *Config.sh [Bug #419812]

	* tests/cmdMZ.test (cmdMZ-1.4): added notLinux constraint to test
	to prevent failure message on Linux due to OS caching bug.

	* tests/httpd (httpdRespond): added response to timeout value in
	query string.

	* tests/http.test: removed unused notLinux constraint setting

	* generic/tclRegexp.c (Tcl_RegExpExecObj): added use of
	Tcl_GetUnicodeFromObj.

2001-05-19  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* Note that "tclbench" (see project "tcllib") was extended with
	  performance benchmarks for [fcopy] too.

	* doc/fcopy.n: Updated to reflect the extended behaviour of 'fcopy'.

	* tests/io.test: Added tests 'io-52.9', 'io-52.10' and 'io-52.11'
	  to test the handling of encodings by 'fcopy' / 'TclCopychannel'
	  [Bug #209210].

	* generic/tclIO.c: Split of both 'Tcl_ReadChars' and
	  'Tcl_WriteChars' into a public error checking and an internal
	  working part. The public functions now use the new internal
	  ones. The new functions are 'DoReadChars' and 'DoWriteChars'.
	  Extended 'CopyData' to use the new functions 'DoXChars' when
	  required by the encodings on the input and output channels
	  [Bug #209210].

2001-05-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* library/history.tcl (tcl::HistAdd): prevent empty calls from
	being added to the history (arndt)

	* tests/error.test: updated error-1.3 message to account for
	string index being compiled at toplevel.
	* tests/appendComp.test:
	* tests/stringComp.test: new files for extended bytecode testing

	* generic/tclBasic.c: added new CompileProc invocations to basic
	command initialization.
	* generic/tclCompCmds.c: added new compile commands for append,
	lappend, lindex and llength.  Refactored set and incr compile
	commands to use new TclPushVarName function for handling the
	varname component during compilation (also used by append and
	lappend).  Changed string compile command to compile toplevel code
	as well (when possible).
	* generic/tclCompile.c: added new instruction enums
	* generic/tclCompile.h: added debug info for new instructions
	* generic/tclExecute.c (TclExecuteByteCode): moved elemPtr to
	toplevel var (oft-used).  Added definitions for new bytecode
	instructions INST_LIST_INDEX, INST_LIST_LENGTH, INST_APPEND_SCALAR1,
	INST_APPEND_SCALAR4, INST_APPEND_ARRAY1, INST_APPEND_ARRAY4,
	INST_APPEND_ARRAY_STK, INST_APPEND_STK, INST_LAPPEND_SCALAR1,
	INST_LAPPEND_SCALAR4, INST_LAPPEND_ARRAY1, INST_LAPPEND_ARRAY4,
	INST_LAPPEND_ARRAY_STK, INST_LAPPEND_STK.
	Refactored repititious code for reuse with INST_LOAD_STK (same as
	INST_LOAD_SCALAR_STK), INST_STORE_STK (same as
	INST_STORE_SCALAR_STK).
	Updated INST_STR_CMP with style of fix of 2001-04-06 Fellows
	[Bug #219201] as that fix only affected the runtime eval'ed
	"string" (string compare is normally byte-compiled now).  We
	may want to back these out for speed in the future, noting the
	problems with \x00 comparisons in the docs.
	* generic/tclInt.h: declarations for new compile commands.
	* generic/tclVar.c: change TclGetIndexedScalar,
	TclGetElementOfIndexedArray, TclSetElementOfIndexedArray and
	TclSetIndexedScalar to use flags.  The Set functions now support
	TCL_APPEND_ELEMENT and TCL_LIST_ELEMENT as well.
	* generic/tclInt.decls:
	* generic/tclIntDecls.h: minor signature changes for above.

	* generic/tclCmdMZ.c: made use of new Tcl_GetUnicodeFromObj.

2001-05-16  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/console.n: Deleted.  Put it in the wrong source tree!  D'oh!

2001-05-15  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tcl.decls:
	* generic/tclDecls.h:
	* generic/tclStubInit.c:
	* generic/tclStringObj.c (Tcl_GetUnicodeFromObj): new function to
	parallel Tcl_GetStringFromObj (fix of an API oversight).

	* unix/tclUnixPipe.c: updated pipeChannelType to
	TCL_CHANNEL_VERSION_2 type specification.

	* tests/fileName.test: corrected tests not to fail on win when a
	C:/test dir exists.

	* generic/tclFileName.c (ExtractWinRoot): corrected ABR error

	* generic/tclNamesp.c: invalidate all bytecodes in a namespace if
	a new command shadows a bytecoded command.
	* tests/namespace.test
	Patched from [Bug: 231259] 

2001-05-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/console.n: Created.  It seems very odd to me that the
	console implementation is part of the Tcl distribution and not
	part of Tk, but given the location of the source, the
	documentation must obviously match up...

2001-05-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): 
	* tests/string.test (string-4.14): Negative string indices should
	not be added as offsets to the result of [string first] but
	instead be treated as referring to the start of the string.
	[Bug: 423581]

2001-05-11  Mo DeJong  <mdejong@redhat.com>

	* unix/Makefile.in: Add a LDFLAGS variable to the

	* unix/configure: Regen.
	* unix/tcl.m4: Fix CFLAGS_DEFAULT so that the name
	of a Makefile variable is passed as @CFLAGS@.
	* win/Makefile.in: Move the setting of CFLAGS
	higher up in the Makefile.
	* win/configure: Regen.
	* win/configure.in: Use dnl to comment out macros

2001-05-03  Don Porter  <dgp@users.sourceforge.net>

	* doc/library.n:
	* library/init.tcl:
	* tests/autoMkindex.t*: Modified [auto_import] to apply
	pattern matching in the [namespace import] style.  [Bug 420186]
	***POTENTIAL INCOMPATIBILITY*** for any callers of [auto_import]
	from outside Tcl that expect the pattern matching to be like that
	of [string match].

2001-05-03  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclParse.c: 
	* tests/namespace.test: Insure consistent behaviour of the
	[unknown] command: when a command is unknown, it is always
	processed by [::unknown], ignoring any namespace proc which
	happens to be called "unknown" [Patch #421166, Bug #420507]

2001-05-02  Don Porter  <dgp@users.sourceforge.net>

	* tools/genStubs.tcl: Add a package require of Tcl 8
	at the beginning of the script so that the script
	will print a descriptive error message when run
	in an old Tcl 7 shell.

	instances of STUB_LIB_FILE with TCL_STUB_LIB_FILE.

2000-04-25  Mo DeJong  <mdejong@redhat.com>

	* unix/Makefile.in: Use TCL_STUB_LIB_FILE instead of STUB_LIB_FILE.

	* tools/encoding/iso8859-15.txt:
	* library/encoding/iso8859-15.enc:
	* tools/tcl.wse.in: Added ISO 8859-15 (a.k.a. Latin-1 + Euro
	currency symbol) support.

	[Patch #415179]
	***POTENTIAL INCOMPATIBILITY*** from 8.4a2, in which Vince
	Darley's changes to command tracing were added.  A const has been
	added to the type signature of one of the parameters to
	Tcl_CommandTraceProc.

2001-04-10  Kevin B. Kenny    <kennykb@acm.org>
	* unix/tclUnixTime.c: Altered code to use memcpy instead of
	structure assigments in an effort to achieve better K&R
	compatibility.
	
2001-04-10  Kevin B. Kenny    <kennykb@acm.org>

	* unix/tclUnixTime.c: Fixed silly typo in calls to 'gmtime' and
	'localtime' that broke the Linux build.

2001-04-09  Kevin B. Kenny    <kennykb@acm.org>

	* unix/tclLoadShl.c: Added DYNAMIC_PATH to the load flags so that
	the SHLIB_PATH will be searched for other libraries.  [Bug #219140]
	
2001-04-09  Kevin B. Kenny    <kennykb@acm.org>

	* unix/tcl.m4: Added _REENTRANT to Solaris build so that thread
	safe library routines are included.
	* unix/configure: Re-ran 'autoconf' with changed tcl.m4
	* tclUnixTime.c: Modified for thread safety of 'gmtime' and
	'localtime' system calls [Bugs #219136 and #232558]
	
2001-04-09  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/expr.test (expr-21.*): Tests to check below fix.
	* generic/tclParseExpr.c (GetLexeme): Now recognises the
	non-numeric boolean literals for what they are. It no longer makes
	sense for anyone to create functions with the same name as one of
	them, but this was true in 7.* as well [Bug #217777; finally!]

2001-04-07  Miguel Sofer <msofer@users.sourceforge.net>

	* generic/tclExecute.c: Avoid panic when there are extra items in

	  definitions as found in the compiled library against the
	  manpages to find undocumented public functionality.

	* unix/mkLinks: Updated to include the new manpage.

	* doc/UniCharIsAlpha.3: New manpage documenting the Unicode

2001-04-07  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* unix/mkLinks: Updated to incorporate the changes below.

	* doc/StringObj.3: Added 'Tcl_AttemptSetObjLength' to the NAME
	  section. [Bug #414435].

	* doc/Alloc.3: Added both 'Tcl_AttemptAlloc' and
	  'Tcl_AttemptRealloc' to the NAME section. [Bug #414435].

	* doc/Utf.3: Added both 'Tcl_UniCharCaseMatch' and
	  'Tcl_UniCharNcasecmp' to the NAME section. [Bug #414435].

	cover the tracks of auto-loading.  [Bug 219280, Patch 403551]

2001-04-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	[Bug #219402]

	* tests/string.test (string-2.30): Test for this case
	* generic/tclCmdMZ.c (Tcl_StringObjCmd, STR_COMPARE branch): Fixed
	problem caused by Utf-rep of \x00 being more than Utf-rep of \x01
	fooling memcmp by forcing everything through Utf-based
	comparisons.  Added optimizations for case where objects have a
	string/unicode-rep or a bytearray-rep (i.e. where we can perform
	comparisons on fixed-size units.) [Bug #219201]
	* generic/tclUtf.c (Tcl_UtfNcmp): Corrected seriously erroneous
	comment.

2001-04-05  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* doc/Macintosh.3: Removed duplicates from .SH line

2001-04-04  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/configure:
	* unix/tcl.m4: extended test of termios vs. termio vs. sgtty to

	redirections are being used. (max) [Patch #402923; Bug #227412,
	#219194]

2001-04-04  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclListObj.c (Tcl_SetListObj): set objPtr->length = 0 in

	* generic/tclCkalloc.c (TclFinalizeMemorySubsystem): set curTagPtr
	to NULL to allow for reuse.
	* generic/tclEvent.c (Tcl_Finalize): moved the tsdPtr
	initialization inside the subsystemsInitialized check to prevent
	it potentially getting called twice during finalization.  (wu)
	[Patch #403532, Bug #219391]

	* generic/tclThreadTest.c (Tcl_ThreadObjCmd): cast fixes
	* generic/tclTest.c (TestChannelCmd): added cast to mollify

	dependency.

2001-03-30  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* All of the changes below belong to TIP #10 [Tcl I/O Enhancement:
	  Thread-Aware Channels]. See also [Patch #403358] at SF.

	* generic/tclIO.h (struct ChannelState, line 236f): Extended the
 	  structure with a new field of type 'Tcl_ThreadId' to hold the id
 	  of the thread currently managing all channels with this state.

	  Note: This structure is shared by all channels in a stack of
 	  transformations.

	* generic/tclIO.c (Tcl_CreateChannel, lines 1058-1065): Modified
 	  to store the Id of the current thread in the 'ChannelState' of
 	  the new channel.

	* generic/tclIO.c (Tcl_SpliceChannel, lines 2265-2270): Modified
 	  in the same manner as 'Tcl_CreateChannel' as the channel will be
 	  managed by the current thread afterward.

	* generic/tclIO.c   (Tcl_GetChannelThread, lines 1478-1503):
	* generic/tcl.decls (Tcl_GetChannelThread, lines 1504-1506): New
 	  API function to retrieve the Id of the managing thread from a
 	  channel. Implementation and declaration.

	* generic/tclTest.c (TestChannelCmd, lines 4520-4532): Added
 	  subcommand 'mthread' to query a channel about its managing
 	  thread.

2001-03-29  Mo DeJong  <mdejong@redhat.com>

	* tests/interp.test: Print out warning when
	testinterpdelete command is not defined.
	Add tests that checks to make sure a
	child interp inherits the parent's cwd.

2001-03-29  Jeff Hobbs  <jeffh@gimlet.activestate.com>

	* doc/tcltest.n: corrected incorrect macro usage.

	* doc/lsort.n: corrected unbalanced nroff macros.

	* unix/tclUnixPipe.c (TclpCreateTempFile): prevent potential race
	condition and security leak in tmp filename creation.
 	(max) [Patch #402924]

	* unix/configure:
	* unix/tcl.m4: corrected IRIX-5.x config to not use -n32.
 	(english) [Patch #403626]

	* unix/tclUnixThrd.c (Tcl_ConditionWait): fixed handling of
	timeout for threads (corrects excessive CPU usage issue for Tk on
	Unix in threaded Tcl environment). (ruppert) [Bug #411603]

2001-03-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/lsort.n: Added some notes that clarify the behaviour of
	[lsort] as well as a whole bunch of examples.  [Bug #219202]

2001-03-27  Jeff Hobbs  <jeffh@gimlet.activestate.com>

	* doc/Alloc.3: corrected docs to note that Tcl_Attempt* return
	char *'s, not ints. [Bug #411388]

	* tests/regexp.test (regexp-19.1):
	* generic/tclCmdMZ.c (Tcl_RegsubObjCmd): fixed handling of nulls
	in subspec value.

2001-03-26  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclDecls.h (Tcl_InitCustomHashTable):  Correction to
	patch from 2001-01-18;  tclDecls.h was not generated using
	'make genstubs'.

2001-03-26  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* win/tclWinInt.h (tclWinTCharEncoding): Removed as now a static
	variable in win/tclWin32Dll.c instead.

2001-03-23  Jeff Hobbs  <jeffh@activestate.com>

	* generic/tclVar.c (Tcl_ArrayObjCmd): Corrected retrieval of
	resultPtr to prevent possible corruption.

	* generic/tclNamesp.c (Tcl_Import): Correctly freed a DString.
 	(lavana) [Patch #403755]

2001-03-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/set-old.test (set-old-7.2): Changed error behaviour of
	[unset] to agree with documentation, so must change test as well.

2001-03-14  Don Porter  <dgp@users.sourceforge.net>

	* library/package.tcl (pkg_mkIndex):  Added patch from Vince
	Darley to make [pkg_mkIndex -verbose] even more verbose.
	[Bug 219349, Patch 403529]

2001-03-13  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/info.n: Improved documentation for [info hostname].
	[Bug #403840]

	* generic/tclVar.c (Tcl_UnsetObjCmd): Made command behave as
	documented [issue remaining from bug #405769]

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): A missing
	{return TCL_OK;} was causing memory corruption.  [Bug #408002]

	* generic/tclExecute.c (TclDeleteExecEnv, GrowEvaluationStack,
	TclExecuteByteCode): Added some casts to ClientData that are
	apparently needed on some architectures.

2001-03-12  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/string.test: Fixed some test numberings and added a test.
	[Patch #403229]

2001-03-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclVar.c (Tcl_UnsetObjCmd): Rewrote argument parser to
	avoid a read off the end of the argument array that could occur
	when executing something like [unset -nocomplain] was executed.
	Improved the error message given when too few arguments are given
	(-nocomplain should obviously be *before* --, not after it) and
	also modified the test suite to take account of that and the
	documentation to use the same improvement. [Bug 405769]

2001-03-02  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): Fixed bug that could
	pass pointers to freed memory to command implementations, which
	most obviously caused some weird behaviour with [info level], but
	could have caused problems with user code and command traces too.
	[Bug 404865, Patch 405436]

2001-02-23  msofer  <msofer@users.sourceforge.net>
	* no changes; fixing up the missing comment in the previous one.
	Sorry.

2001-02-23  msofer  <msofer@ant.utdt>

	* /cvsroot/tcl/tcl/tests/execute.test:
	added test for evaluation of an expression in a variable; evals once
	by compiling, second time using the previous compilation

2001-02-18  Kevin B. Kenny  <kennykb@acm.org>

	* doc/clock.n: Updated documentation to reflect the addition of
	compat/strftime.c, including the correct formatting of
	ISO-8601:1988 fiscal week number (%V).
	
2001-02-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdMZ.c (Tcl_SplitObjCmd): Improved efficiency of
	splitting strings into individual characters by adding hash so
	that only one Tcl_Obj per character is created.  Improves
	performance of splitting of short strings and makes a huge
	difference to splitting of long strings, such as is done in the
	mime package in tcllib.  [Bug #131523]

2001-01-31  Don Porter  <dgp@users.sourceforge.net>

	* win/makefile.vc (install-libraries):  Corrected misdirected
	install directory for the msgcat 1.2 package.

2001-01-30  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclIO.c (CopyData): Moved code that updates the count
	of how many bytes are left to copy.  Corrects bug that when
	writing occurs in the background, the copy loop could be
	escaped without updating the count, causing CopyData() to try
	to copy more bytes than the toRead value originally passed to
	TclCopyChannel(), leading to hangs and misreporting of number
	of bytes copied. [Bug 118203, Patch 103432]

2001-01-18  Andreas Kupries  <a.kupries@westend.com>

	* Everything below belongs together, it fixes bug #123153.

	* generic/tcl.h (line 342): A bit more explanation about the
	  default value for TCL_PRESERVE_BINARY_COMPATABILITY.

	* generic/tcl.h (line 1208): Define the macro 'Tcl_InitHashTable'
	  only when TCL_PRESERVE_BINARY_COMPATIBILITY is not set
	  as it kills binary compatibility to 8.3 and earlier
	  versions. This is the main part of the patch/change.

	* generic/tcl.decls (line 1469):
	* generic/tclHash.c (Tcl_InitHashTable):
	* generic/tclHash.c (Tcl_InitHashTableEx):
	* generic/tclObj.c (Tcl_InitObjHashTable): Changed
	  'Tcl_InitHashTableEx' to 'Tcl_InitCustomHashTable'. This change
	  is more of an estethical nature, replacing the ubiquitous 'Ex'
	  suffix with a more meaningful name. The introduced binary
	  incompatibility is deemed acceptable as it is between alpha
	  versions.  Updated callers.

	* doc/Hash.3:
	* unix/mkLinks: Changed 'Tcl_InitHashTableEx' to
	  'Tcl_InitCustomHashTable'.

2001-01-10  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/winPipe.test (winpipe-1.20): 
	* tests/winDde.test (createChildProcess): 
	* tests/pkgMkIndex.test (pkgtest::createIndex):  Removed
	assumption that paths contain no spaces which causes problems with
	both [eval] and [open |...] due to the well-known differences
	between lists and strings.  Fixes bug #119406

2001-01-04  Don Porter  <dgp@users.sourceforge.net>

	* tests/unixInit.test:
	* unix/tclUnixInit.c (TclpInitLibraryPath):
	* win/tclWinInit.c (TclpInitLibraryPath):  Several entries in
	the library path ($tcl_libPath) are determined relative to the
	absolute path of the executable.  When the executable is
	installed in or near the root directory of the file system,
	relative pathnames were being incorrectly generated, and in
	the worst case, memory access violations were crashing the program.
	[Bug 119416, Patch 102972]

2000-12-14  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c:
	* tests/expr-old.test:  Re-wrote Tcl's [expr rand()] and
	[expr srand($seed)] implementations, fixing a range error
	on some 64-bit platforms.  Added tests that detect the bug.
	The rewrite changes the seed -> sequence map on 64-bit
	platforms, only for seed >= 2^31, a slight incompatibility.
	[Bug 121072, Patch 102781]

2000-12-10  Don Porter  <dgp@users.sourceforge.net>

	* library/init.tcl:
	* library/msgcat/msgcat.tcl:
	* library/msgcat/pkgIndex.tcl:
	* library/opt/optparse.tcl:
	* library/opt/pkgIndex.tcl: Where [uplevel] is used in a proc
	to evaluate a Tcl built-in command in the caller's context,
	the built-in commands are now fully namespace-qualified.  This
	prevents problems when the caller context is in a namespace where
	the built-in command name has been used by a command in the
	namespace.  (For example, [::ns::set] might be called instead
	of the intended [::set]).  [Bug #119422, Patch #102545]

2000-12-09  jeff hobbs  <jhobbs@interwoven.com>

	* win/tclWinTime.c (CalibrationThread): added lint return value to
	prevent compiler warning.  [Bug #125005]

	* docs/scan.n:
	* tests/scan.test:
	* generic/tclScan.c (Tcl_ScanObjCmd): changed %o and %x to use
	strtoul instead of strtol to correctly preserve scan<>format
	conversion of large integers.  [Patch #102663, Bug #124600]

	* generic/tclExecute.c (TclExecuteByteCode): Commited patch fixing
	handling of {!<boolean>} in expressions. [Patch #102702]

2000-12-08  jeff hobbs  <jhobbs@interwoven.com>

	* library/init.tcl: Added support for PATHEXT variable in
	auto_execok, recognizing the proper set of executable extensions
	on Windows.  [Patch #102719]

2000-12-08  Andreas Kupries  <a.kupries@westend.com>

	* generic/tclEncoding.c (LoadTableEncoding): Changed dangerous
	  code to something less critical. This fixes bug 119417, part A
	  without affecting the speed when loading encodings.

2000-12-08  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/open.n: Added xref to fconfigure and advice on the opening
	  of binary files.  Should help prevent a recurrence of bugs like
	  #124558

2000-12-07  jeff hobbs  <jhobbs@interwoven.com>

	* generic/tcl.h: added note about need to updated
	library/dde/pkgIndex.tcl with minor version increment.

	* library/dde/pkgIndex.tcl: updated to use 84 version to reflect
	the makefile.  Should probably be updated to use its real version
	at some point. [Patch #102560, Bug #119421]

2000-12-06  eric melski  <ericm@ajubasolutions.com>

	* generic/tcl.h (attemptckalloc): Fixed typo for #define of
	attemptckalloc (was defined to Tcl_AttempDbCkalloc, should have
	been Tcl_AttemptDbCkalloc). [Bug: 124384]

	* generic/tclCkalloc.c: Added
	TCL_MEM_DEBUG versions of Tcl_AttemptDbCkrealloc and
	Tcl_AttemptDbCkalloc. [Bug: 124384].

2000-11-24  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): Logical negation "!"
	  can now handle string booleans, provided those values are placed
	  in variables.

	* tests/expr.test (expr-13.17): Check that [expr {!$var}] can
	  negate the string-versions of booleans "yes", "false", etc.

	* library/tcltest/tcltest.tcl (getMatchingFiles,
	  getMatchingDirectories):
	* tools/man2html.tcl (doDir): 
	* tools/man2help.tcl (doDir): 
	* library/package.tcl (tclPkgUnknown,tclMacPkgSearch): 
	* library/safe.tcl (AddSubDirs): [glob] uses -directory instead of
	  unsafe [file join] to fix Bug #123313

	* generic/tclIndexObj.c:
	* generic/tclTestObj.c (TestindexobjCmd): Changed internal
	  representation of index objects to fix Bug #119082; fix
	  shouldn't be visible to outside world...

	* generic/tclTest.c (TestGetIndexFromObjStructObjCmd): 
	* tests/indexObj.test: (indexObj-6.*) Added to test for presence
	  of Bug #119082.

2000-11-23  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Fixed memory leak from Bug
	  #119398

	* library/init.tcl (unknown): Added specific level parameters to
	  all uplevel invokations to boost performance; didn't dare touch
	  the "namespace inscope" stuff though, since it looks sensitive
	  to me!  Should fix Bug #123217, though testing is tricky...

2000-11-21  Andreas Kupries  <a.kupries@westend.com>

	* All of the changes below are described in TIP #7 ~ Specification
 	  and result from the application of the patch contained
 	  therein. Creator of the patch is Kevin Kenny
 	  <kennykb@crd.ge.com>. The patch used here is actually a bit
 	  different. Two MS specific constant values (format FOOui64) were
 	  replaced with a more portable formatting of the values and an
 	  additional cast to LONGLONG. My cross-compiling gcc was unable to
	  process the original form. The SF Id of the patch is 102459.

	* tclWinTime.c: Add to the static data a set of variables that
 	  manage the phase-locked techniques, including a
 	  ''CRITICAL_SECTION'' to guard them so that multi-threaded code
 	  is stable.

	* tclWinTime.c: Modify ''TclpGetSeconds'' to call ''TclpGetTime''
 	  and return the 'seconds' portion of the result.  This change is
 	  necessary to make sure that the two times are consistent near
 	  the rollover from one second to another.

	* tclWinTime.c: Modify ''TclpGetClicks'' to use TclpGetTime to
 	  determine the click count as a number of microseconds.

	* tclWinTime.c: Modify ''TclpGetTime'' to return the time as
 	  M*Q+B, where Q is the result of ''QueryPerformanceCounter'', and
 	  M and B are variables maintained by the phase-locked loop to
 	  keep the result as close as possible to the system clock.  The
 	  ''TclpGetTime'' call will also launch the phase-lock management
 	  in a separate thread the first time that it is invoked.  If the
 	  performance counter is unavailable, or if its frequency is not
 	  one of the two common 8254-compatible rates, then
 	  ''TclpGetTime'' will return the result of ''ftime'' as it does
 	  in Tcl 8.3.2.

	* tclWinTime.c: Add the clock calibration procedure.  The
 	  calibration is somewhat complex; to save space, the reader is
 	  referred to the reference implementation for the details of how
 	  the time base and frequency are maintained.

	* tclWinNotify.c: Modify ''Tcl_Sleep'' to test that the process
 	  has, in fact, slept for the requisite time by calling
 	  ''TclpGetTime'' and comparing with the desired time.  Otherwise,
 	  roundoff errors may cause the process to awaken early.

	* tclWinTest.c: Add a ''testwinclock'' command.  This command
 	  returns a four element list comprising the seconds and
 	  microseconds portions of the system clock and the seconds and
 	  microseconds portions of the Tcl clock.

	* winTime.test: Add to the test suite a test that makes sure that
 	  the Tcl clock stays within 1.1 ms of the system clock over the
 	  duration of the test.

2000-11-21  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/global.n: 
	* doc/upvar.n: 
	* doc/variable.n: Improved documentation to mention that variables
	  so created are listed in [info locals] and added a few more
	  cross-links between these commands.  Fixes bug #119387

2000-11-17  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/safe.test: (safe-4.3):
	* generic/tclVar.c (TclLookupVar): Changed again.  Now passes all
	  the tests, though one needed modifying since it required the
	  wrong answer.  (Why on earth do we have inline modification of
	  argument strings?  This sort of thing is horrendous to debug and
	  doesn't work well in a multithreaded environment!)  Fixes bug
	  119192.

	* tests/var.test: (var-1.19) If my attempts to fix the problem
	  aren't right yet, my attempts to describe it look pretty good to
	  me...

2000-11-16  Andreas Kupries  <a.kupries@westend.com>

	* win/tclWinPort.h (line 69): Changed reference to winsock2.h into
 	  winsock.h. This was a leftover from a foray into using winsock
 	  version 2 (History lesson from Scott Redman and Jeff
 	  Hobbs). This code was no problem when compiling Tcl itself, but
 	  could trip extensions. Fixes bug 122568.

2000-11-15  jeff hobbs  <jeff.hobbs@acm.org>

	* unix/Makefile.in: removed bp.c references (hasn't existed in a
	  long time).  Corrected 'make dist' to make dist with unversioned
	  library directories (same as out of cvs), so make install works
	  correctly with either source tree.

2000-11-15  jeff hobbs  <jeff.hobbs@acm.org>

	* generic/tclVar.c (TclLookupVar): reverted fix below as it broke
	  all other array unset error reporting.  Bug-119192 is still
	  open.

2000-11-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclVar.c (TclLookupVar): Changed references to part2 to
	  use elName instead in various error message generating spots, so
	  as to fix Bug-119192.

2000-11-03  David Gravereaux  <davygrvy@ajubasolutions.com>

	* win/.cvsignore: Removed 'configure' from the glob list now
	  that it's included.

2000-11-03  Jeff Hobbs  <hobbs@ajubasolutions.com>

	8.4a2 RELEASE

	* unix/Makefile.in (install-libraries, dist): 
	* win/makefile.vc (install-libraries):
	* win/Makefile.in (install-libraries): updated to install
	unversioned library directories into versioned directories.

	* tools/tcl.wse.in: updated for unversioning of library dirs

	* unix/mkLinks: updated mkLinks with latest doc updates

	* doc/Tcl_Main.3: added docs for Tcl_SetMainLoop

	* generic/tclStubInit.c:
	* generic/tclDecls.h:
	* generic/tcl.decls: added Tcl_SetMainLoop proc that allows people
	to set a main loop that will run for tclsh.
	* generic/tcl.h: added Tcl_MainLoopProc typedef
	* generic/tclMain.c (Tcl_SetMainLoop, StdinProc, Prompt): new
	StdinProc and Prompt static procs and Tcl_SetMainLoop stubs proc.
	The first two handle a fileevent based prompt (taken from
	tkMain.c).  Tcl_SetMainLoop enables the interactive setting of a
	main loop procedure.  This enables Tk to be a loadable package.

2000-11-02  David Gravereaux  <davygrvy@ajubasolutions.com>

	* generic/tclEvent.c: tclLibraryPath Tcl_Obj didn't have a way
	to share its data among threads.  This caused Tcl_Init() to
	always fail in threads.  Added a way to pass the data around
	with a global char*.  [BUG: 5301]

2000-11-02  Jeff Hobbs  <hobbs@ajubasolutions.com>

	* unix/configure:
	* unix/dltest/configure:
	* win/configure:
	* tools/configure: checked in configure scripts so people doing
	CVS checkouts aren't required to have autoconf.  Changes to
	configure.in in the future will require the corresponding
	configure script to also be re-autoconf'ed and checked in.

	* win/makefile.vc:
	* win/tcl.m4: makefile fixes for Win64 support

	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): minor cast
	changes.

2000-11-01  Jeff Hobbs  <hobbs@ajubasolutions.com>

	* unix/tcl.m4: removed use of -lbsd and -ldl for AIX-5.

	* tests/subst.test: added tests for non-zero return code handling
	by subst.
	* generic/tclParse.c (Tcl_EvalEx): corrected handling of non-zero,
	non-error return code cases for subst. [BUG: 119829]

	* generic/tclVar.c (TclVarTraceExists): Corrected excessive mem
	use when info exists was called on a non-existent array element.
	[BUG: 119213, 119336]

2000-10-30  David Gravereaux  <davygrvy@ajubasolutions.com>

	* win/configure.in:
	* win/Makefile.in:
	* win/makefile.vc:
	* win/tcl.rc:
	* win/tclsh.rc: Added logic to derive filenames better in the resource
	scripts based on compile options.

2000-10-30  Jeff Hobbs  <hobbs@ajubasolutions.com>

	* unix/tclUnixInit.c: added default encoding map from
	"ja_JP.eucJP" to "euc-jp". (takahashi)

	* tests/clock.test: corrected clock-2.* test numbering

	* unix/configure.in (SC_TCL_LINK_LIBS): removed code that was
	commented out (it had been moved to tcl.m4's SC_TCL_LINK_LIBS
	already).

	* unix/tcl.m4: consolidated gettimeofday check for AIX.

2000-10-27  Jeff Hobbs  <hobbs@ajubasolutions.com>

	* unix/configure.in:
	* unix/tcl.m4: added support for AIX-5.

	* generic/tclIO.c (Tcl_NotifyChannel): removed #ifdef around code
	for old channel structures, placed preserve/release around statePtr
	* generic/tclIO.c (CloseChannel): the statePtr for a channel was
	not being freed when the last channel in a stack was freed,
	causing a mem leak.

	* unix/tclUnixChan.c: updated channel types to strict
	TCL_CHANNEL_VERSION_2 style to avoid compiler warnings.  They work
	either way, but this avoids compiler warnings (that worries people).

2000-10-27  Jennifer Hom  <jenn@ajubasolutions.com>

	* library/tcltest1.0/tcltest.tcl: Removed a cd into the test
	directory in runAllTests that screwed up the temporary directory
	setting, effectively preventing users from running tests on
	multiple platforms at the same time.

2000-10-26  David Gravereaux <davygrvy@ajubasolutions.com>

	* win/tclWinFile.c (TclpMatchFilesTypes): NULL was being set to
	"attr" which was a DWORD.  Changed NULL to zero because a 'void *'
	can't be set to a DWORD to avoid the compiler warning.

2000-10-24  Jennifer Hom  <jenn@ajubasolutions.com>

	* tests/all.tcl: Removed support for tcltest 1.0.
	
	* tests/tcltest.test:
	* library/tcltest1.0/tcltest.tcl:
	* library/tcltest1.0/pkgIndex.tcl:
	* docs/tcltest.n: Moved tcltest2 code so that it's the standard
	version of tcltest.  Removed all tcltest2 files
	(tests/tcltest2.test, library/tcltest1.0/tcltest2.tcl,
	docs/tcltest2.n). 

2000-10-20  Jeff Hobbs  <hobbs@ajubasolutions.com>

	* win/tclWinFile.c (TclpMatchFilesTypes): made the stat call only
	occur when necessary (for 'glob' command).  Significantly speeds
	up glob command from 8.3. [BUG: 6216]

2000-10-19  Jennifer Hom  <jenn@ajubasolutions.com>

	* library/tcltest1.0/tcltest2.tcl:
	* tests/tcltest2
	* doc/tcltest2.n: Code and documentation cleanup.  Modified
	-verbose to take list of keywords as well as string of letters.
	Removed Tcl version information from tcltest. Removed
	tcltest::grep from tcltest package. Added optional 3rd directory
	argument to  makeFile/makeDirectory and removeFile/removeDirectory.

	* tests/basic.test: Changed references to tcltest::tclVersion to
	hardcoded numbers.
	* generic/tcl.h: Changed reference to tcltest2.tcl and tcltest.tcl
	in comments to tests/basic.test.

2000-10-06  David Gravereaux  <davygrvy@ajubasolutions.com>

	* win/tclWinChan.c: moved Win2K bug case test with GetStdHandle()
	from TclpGetDefaultStdChannel into Tcl_MakeFileChannel to enable
	a more general method in detecting invalid OS handles rather than
	just a specific known case. [BUG: 5971]

2000-10-06  Jeff Hobbs  <hobbs@ajubasolutions.com>

	* tests/cmdAH.test: extra tests for 'file channels' that include
	multiple interpreter tests and channel sharing
	* generic/tclIO.c (Tcl_GetChannelNamesEx): corrected function (and
	consequently 'file channels') to return channels that are actually
	registered for this specific interp, rather than this thread.

	* doc/CrtChannel.3: fixed spelling mistakes

2000-09-29  Jennifer Hom  <jenn@ajubasolutions.com>

	* library/tcltest1.0/tcltest2.tcl:
	* tests/tcltest2.test:
	* doc/tcltest2.n: Modified the new form of the test command to
	accept both attribute-value pairs and command line options.
	Updated the tests and the documentation for this new format.
	Also changed the option names for the test command.

2000-09-29  Jeff Hobbs  <hobbs@scriptics.com>

	* win/tclWinSerial.c (SerialGetOptionProc): corrected reporting of
	space parity on Windows (Eason) [Bug 6057].

	* win/Makefile.in: commented use of TESTFLAGS
	* unix/Makefile.in: added TESTFLAGS to test target to
	conform with Windows makefile and TEA style.

	* tests/stack.test: prevented possible crash on systems with low
	default stacksize (Tru64, AIX) in infinite recursion test.  A
	solution to check remaining stack space in the core is best, but
	hard to do in a cross-platform manner.

	* generic/tclIOGT.c (FLUSH_DELAY): renamed DELAY define to
	FLUSH_DELAY to avoid defn conflict using Tru64's cc.

2000-09-28  Jeff Hobbs  <hobbs@ajubasolutions.com>

	* tools/tcl.wse.in: added tclPlatDecls.h and tkPlatDecls.h to the
	Windows .exe install.

	* tests/fCmd.test (fCmd-6.20): corrected test to remove
	c:/tcl8975@ after creating it.

	* tests/fileName.test: cleaned up the testing of glob patterns for
	c:/globTest (Windows) to directly create/remove directory.

2000-09-27  Jeff Hobbs  <hobbs@ajubasolutions.com>

	* generic/tcl.decls:
	* generic/tclIO.c: updated Tcl_IsChannelShared,
	Tcl_IsChannelRegistered, Tcl_CutChannel, Tcl_SpliceChannel,
	Tcl_IsChannelExisting, and Tcl_ClearChannelHandlers to conform to
	the new stacked channel implementation.  Their stub slots were
	also moved to give preference to the new 8.3.2 stub functions.
	This will cause an incompatability with 8.4a1 only.
	(StopCopy): fixed a bug introduced by a partial fix in 8.3.2 that
	didn't set nonBlocking correctly when resetting the flags for the
	write side.  [Bug: 6261]

	* doc/ChnlStack.3:
	* doc/CrtChannel.3:
	* generic/tcl.decls:
	* generic/tcl.h:
	* generic/tclDecls.h:
	* generic/tclIO.c:
	* generic/tclIO.h:
	* generic/tclIOGT.c:
	* generic/tclInt.decls:
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c:
	* generic/tclTest.c:
	* tests/iogt.test:
	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.vc:

	* win/tclWinChan.c:
	* win/tclWinConsole.c:
	* win/tclWinPipe.c:
	* win/tclWinSerial.c:
	* win/tclWinSock.c: Up-port of changes made in 8.3.2 to 8.4a2 code
	base.  Most of these changes relate to the rewrite of the stacked
	channel implementation, with a few config related fixes.

	Following is an asynchronous include of the applicable ChangeLog
	entries from 8.3.2.

	********************************************************
	** START OF ASYNCHRONOUS UP-PORT LOG (8.3.2 -> 8.4a2) **
	********************************************************

2000-08-07  Jeff Hobbs  <hobbs@scriptics.com>

	* doc/ChnlStack.3:
	* doc/CrtChannel.3: updated the docs to be aware of the
	TCL_CHANNEL_VERSION_2 style of Tcl channels.

	* generic/tclIO.c (Tcl_CreateChannel): added assertion to verify
	that the new channel versioning will be binary compatible with
	older channel drivers.

2000-08-05  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclIOGT.c (TclChannelTransform): fixed segfault that
	would occur when transforming a channel with a proc that did not
	yet exist. (Kupries)

	* generic/tclTest.c (TestChannelCmd): added some lint init'ing of
	statePtr and chan vars.

2000-07-26  Jeff Hobbs  <hobbs@scriptics.com>

	* merged core-8-3-1-io-rewrite back into core-8-3-1-branch.
	The core-8-3-1-io-rewrite branch should now be considered defunct.

	* generic/tclStubInit.c:
	* generic/tclDecls.h:
	* generic/tcl.decls:
	* generic/tcl.h:
	* generic/tclIO.c: moved the Tcl_Channel* macros from tcl.h to
	tclIO.c and made them proper stubbed functions.  These are:
	Tcl_ChannelName, Tcl_ChannelVersion, Tcl_ChannelBlockModeProc,
	Tcl_ChannelCloseProc, Tcl_ChannelClose2Proc, Tcl_ChannelInputProc,
	Tcl_ChannelOutputProc, Tcl_ChannelSeekProc, Tcl_ChannelSetOptionProc,
	Tcl_ChannelGetOptionProc, Tcl_ChannelWatchProc,
	Tcl_ChannelGetHandleProc, Tcl_ChannelFlushProc,
	and Tcl_ChannelHandlerProc.  These should be used to access the
	Tcl_ChannelType structure instead of direct pointer dereferencing.

	* tests/iogt.test: added RCS string, marked tests 2.* to be
	unixOnly due to underlying system differences.

2000-07-25 Andreas Kupries <a.kupries@westend.com>

	* tests/iogt.test: (line 866f) New tests iogt-6.[01], highlighting
 	  buffering trouble when stacking and unstacking transformations.
	  iogt-6.0 is solved, see the changes below. iogt-6.1 remains, for
 	  now, due to the perceived complexity of solutions.

	* generic/tclIO.h: (line 139f) struct Channel, added a buffer
	  queue, to hold data pushed back when stacking a transformation.

	* generic/tclIO.c:
	  (line 91f, line 7434f) New internal function 'CopyBuffer'.
	  Derived from 'CopyAndTranslateBuffer', with translation
	  removed.
	  (line 1025f, line 1212f): Initialization of new queue.
	  (line 1164f, Tcl_StackChannel): Pushback of input queue.
	  (line 1293f, Tcl_UnstackChannel): Discard input and pushback.
	  (line 3748f, Tcl_ReadRaw): Modified to use data in the push back
	  area before going to the driver. Uses 'CopyBuffer', s.a.
	  (line 4702f, GetInput): Modified to use data in the push back
	  area before going to the driver.
 	  (line 4867f, Tcl_Seek): Modified to take pushback of the topmost
	  channel in a stack into account.
	  (line 5620f, Tcl_InputBuffered): See above. Added
	  'Tcl_ChannelBuffered'. Analogue to 'Tcl_InputBuffered' but for
	  the buffer area in the channel.

	* generic/tcl.decls: New public API 'Tcl_ChannelBuffered'. S.a.

2000-07-17  Jeff Hobbs  <hobbs@scriptics.com>

	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.vc: added tclIOGT.c to objects list to compile.

	* generic/tclStubInit.c:
	* generic/tclIntDecls.h:
	* generic/tclInt.decls: commented out internal decls for
	TclTestChannelCmd and TclTestChannelEventCmd as they were moved to
	tclTest.c.  Added new decls for TclChannelEventScriptInvoker and
	TclChannelTransform.

	* generic/tclIO.c (CloseChannel): stopped masking out of the
	TCL_READABLE|TCL_WRITABLE bits from the state flags in
	CloseChannel, instead adding extra intelligence to
	CheckChannelErrors with a new CHANNEL_RAW_MODE bit for special
	behavior when called from Raw channel APIs.

2000-07-13  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclIO.c (StackSetBlockMode): moved set of chanPtr
	outside of blockModeProc check to avoid infinite loop when
	blockModeProc was NULL (Kupries).  updated TransformSeekProc to
	not call Tcl_Seek directly (Kupries).

	* win/tclWinChan.c: updated fileChannelType to v2 channel struct
	* win/tclWinConsole.c: updated consoleChannelType to v2 channel struct
	* win/tclWinPipe.c: updated pipeChannelType to v2 channel struct
	* win/tclWinSerial.c: updated serialChannelType to v2 channel struct
	* win/tclWinSock.c: updated tcpChannelType to v2 channel struct

2000-07-11  Brent Welch	<welch@ajubasolutions.com>

	* win/tclConfig.sh.in (TCL_LIBS): Cleaned up unix-specific
	autoconf variables.

2000-07-11  Jeff Hobbs  <hobbs@scriptics.com>

	* tests/iogt.test: made tests [345].0 not run by default as they
	were failing in the new design, but I'm not convinced that the
	returned result isn't correct.

	* generic/tclDecls.h:
	* generic/tclStubInit.c:
	* generic/tcl.decls: added Tcl_GetTopChannel C API that returns
	the current top channel of a channel stack.  Tcl_GetChannel was
	changed earlier to return the bottommost channel of a stack
	because that is the one that is guaranteed to stay around the
	longest, and this was needed to compensate for certain
	operations that want to look at the state of the main channel.
	Most channel APIs already compensate for grabbing the top, so it
	shouldn't be needed often.

	* generic/tclIO.c (Tcl_StackChannel, Tcl_UnstackChannel): Added
	flushing of buffers (Kupries), removed use of DownChannel macro,
	added Tcl_GetTopChannel public API to get to the top channel of
	the channel stack (necessary for TLS).  Rewrote Tcl_NotifyChannel
	for new channel design (Kupries).  Did some code cleanup in the
	transform code.  tclIO.c must still be broken into bits (separate
	out test code and giot code, create tclIO.h).

2000-07-10  Andreas Kupries <a.kupries@westend.com>

	* tests/iogt.test: Reverted some earlier changes as a fix by Jeff
	  revived the original and correct behaviour. IOW, the tests showed
	  a genuine error and I didn't see it :(.

	* generic/tclIO.c (Tcl_Read|Write_Raw): Changed to directly use
 	  the drivers and not DoRead|DoWrite. The latter use the buffering
 	  system, encoding and eol-translation and this wreaks havoc with
 	  the data going through the transformations. Both procedures use
 	  CheckForchannelErrors and let it believe that there is no
 	  background copy in progress or else stacked channels could not
	  be used for that.

	* generic/tclIO.c (TclCopyChannel, CopyData): Moved access to the
 	  topmost channel from the first to the second procedure to make
 	  the decision about that at the last possible time (Callbacks can
 	  change the stacking).

	test suite: failures of iogt-[345].0
	
2000-07-06  Jeff Hobbs  <hobbs@scriptics.com>

	* tests/iogt.test: new tests for stacked channel stuff based off
	new 'testchannel transform|unstack' code (Kupries IOGT extension).
	* generic/tcl.decls:
	* generic/tcl.h:
	* generic/tclDecls.h:
	* generic/tclStubsInit.c:
	* generic/tclIO.c: complete rewrite of Tcl Channel code for
	stacked channels.  Channels are now designed to work in a more
	stacked fashion with a shared ChannelState data structure.

2000-06-02  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclIO.c (CloseChannel): removed the &ing out of
	(TCL_READABLE|TCL_WRITABLE) from the flags, as CloseChannel does
	this on the next pass through for the top channel, and it appeared
	to be causing hangs by not allowing the final flush.

2000-06-01  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclIO.c (CloseChannel): Rewrote CloseChannel code to
	unstack a channel during the close process.  Fixed a refcount bug
	in Tcl_UnstackChannel.  [Bug: 5623]
	(CloseChannel): further extended CloseChannel in the stacked case
	to effect certain operations on the next channel that would have
	been done in Tcl_Close.  Also added CHANNEL_CLOSED and removed
	(TCL_READABLE|TCL_WRITABLE) bits from chanPtr->flags.  Changed
	final reset of the WatchProc to check the chanDownPtr's (next)
	interestMask.

	** END OF ASYNCHRONOUS UP-PORT LOG (8.3.2 -> 8.4a2) **
	******************************************************

2000-09-20  Jeff Hobbs  <hobbs@scriptics.com>

	* tests/socket.test: removed doTestsWithRemoteServer constraint
	from socket-12.*.  It requires 'exec', not a remote server.
	Cleaned up some coding errors.

2000-09-20  Jennifer Hom  <jenn@ajubasolutions.com>

	* library/tcltest1.0/pkgIndex.tcl: Updated to load tcltest 2.0.
	* library/tcltest1.0/tcltest2.tcl: New version of tcltest.  
	Cleanup of command line parsing: allows users to specify command
	line arguments through an environment variable named
	TCLTEST_OPTIONS [RFE: 3748], does not respond to incorrect
	arguments, and forces usage of entire flag name when using command
	line arguments.  Defines accessor procs for all tcltest
	variables.  Allows users to use 'return' in test scripts. Allow
	users to specify whether test files should be sourced or run in a
	separate process.  'all.tcl' code moved to tcltest package.
	'test' proc modified to use attribute-value pairs.  Allow users to
	specify what return codes, output, and errors can be compared and
	whether these values should be compared using regexp, glob, or
	exact matching.  makeDirectory & removeDirectory now operate with
	respect to temporaryDirectory [Bug: 6001].  Test results from
	tests run in slave interpreters are now included in test totals
	[Bug: 1493].  Test files that return error values are now reported.
	
	* tests/all.tcl: Added code to check for the tcltest version
	loaded; modified to figure out which tests to run based on the
	tcltest version loaded.
	* tests/tcltest.test: Modified to explicitly load version 1.0 of
	tcltest.
	* tests/tcltest2.test: New test suite for tcltest; includes all of
	the old tests plus new ones reflecting changes made for version
	2.0.
	* tests/cmdAH.test: Added singleTestInterp constraint to
	cmdAH-31.2; this test does not run if tests aren't sourced into a
	single interpreter.
	* tests/socket.test: Fixed two tests that were referencing
	variables outside of scope.
	
	* tools/tcl.wse.in: Added code to install tcltest2.tcl.

	* doc/tcltest2.n: New documentation for tcltest version 2.0.
	Removes documentation for tcltest namespace variables.  Adds
	documentation for new tcltest procs.

	* unix/mkLinks: Added code to link to tcltest2.n.

	* generic/tcl.h: Added comment to modify tcltest2.tcl as well as
	tcltest.tcl for version changes.

2000-09-19  Eric Melski  <ericm@ajubasolutions.com>

	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd): When using -all, all
	attempts after the first to match the regexp against the string
	should include the TCL_REG_NOTBOL flag, to avoid erroneously
	matching ^ in the middle of the string.  Added code to set this
	flag after the first pass through the matching loop. [Bug: 6284].

2000-09-19  David Gravereaux  <davygrvy@ajubasolutions.com>

	* doc/Eval.3:  Added a note about the script argument to Tcl_Eval()
	should be in UTF-8 or risk implied conversion errors when possible
	combinations of upper ascii can be valid UTF-8 special codes.

2000-09-17  Eric Melski  <ericm@ajubasolutions.com>

	* tests/cmdIL.test: Added a test for fix for [Bug: 6212].

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Applied patch from [Bug:
	6212], which corrected an error in the handling of the -index option.

2000-09-14  Eric Melski  <ericm@ajubasolutions.com>

	* doc/Alloc.3: Added entries for Tcl_AttemptAlloc, Tcl_AttempRealloc.

	* doc/StringObj.3: Added entry for Tcl_AttemptSetObjLength.
	
	* generic/tclDecls.h:
	* generic/tclStubInit.c: Regen'ed stubs files from new tcl.decls.

	* generic/tcl.decls: Added stubs for the Tcl_Attempt* memory
	allocators and for Tcl_AttemptSetObjLength.

	* generic/tcl.h: Added #define's for attemptckalloc,
	attemptckrealloc, which map to the Tcl_Attempt* memory allocators.

	* generic/tclCkalloc.c: Added non-panic'ing versions of Tcl_Alloc,
	Tcl_Realloc, etc.; these are called Tcl_AttemptAlloc,
	Tcl_AttemptRealloc, etc.  These are used by
	Tcl_AttemptSetObjLength and the string obj append functions.

	* generic/tclStringObj.c: Modified string growth algorithm to use
	doubling algorithm as long as possible, and only fall back when
	that fails.  Added Tcl_AttemptSetObjLength, and modified
	AppendUnicodeToUnicodeRep, AppendUtfToUtfRep, and
	Tcl_AppendStringsToObjVA to support this.

2000-09-07  David Gravereaux <davygrvy@ajubasolutions.com>

	* win/.cvsignore: changed the glob patterns a bit to exclude VC++
	project conversion backups.

	* win/tclWinPipe.c: Stage-1 bug fix for TR#2460 "exec leaks memory".
	Added more logic around the close-down of the pipe reader thread so
	as to avoid, at all cost, a TerminateThread.  Most cases with exec
	are fixed, but I don't consider 2460 done yet.  Closing down the
	read side of a pipe before the child process, doesn't really fit
	the windows model.  [BUG: 2460]

2000-09-07  Jeff Hobbs  <hobbs@scriptics.com>

	* doc/trace.n: minor doc cleanup

2000-09-06  André Pönitz <poenitz@htwm.de>

	* doc/*.n: added or changed "SEE ALSO:" section

2000-09-06  Jeff Hobbs  <hobbs@scriptics.com>

	* win/tclWinLoad.c (TclpLoadFile): added special message for
	ERROR_PROC_NOT_FOUND exception in loading a dll.
	* win/tclWinError.c: changed ERROR_PROC_NOT_FOUND to map from
	ESRCH (POSIX: no such process) to EINVAL because there is no good
	mapping for "procedure not found".

	* README:
	* generic/tcl.h:
	* library/tcltest1.0/tcltest.tcl:
	* tools/tcl.wse.in: 
	* tools/tcltk-man2html.tcl:
	* unix/configure.in:

	* win/configure.in: updated patchlevel to 8.4a2

	* unix/tclUnixPipe.c (TclpCreateProcess): Removed WNOHANG from
	Tcl_WaitPid call in error case of process creation on Unix, as it
	would lead to defunct processes. [Bug: 6148]

	* tests/string.test: extended string repeat tests
	* generic/tclCmdMZ.c (Tcl_StringObjCmd): changed STR_REPEAT to
	preallocate the full space of the final string, avoided repeated
	appends.

	* doc/source.n:
	* doc/Eval.3: added extra note about how to safe use ^Z in code,
	as it is now a cross-platform (was just Windows) EOF char.

2000-09-05  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclHash.c: fixed pedantic warning of incorrectly placed
	#endif

	* generic/tclExecute.c (TclExecuteByteCode): INST_STR_INDEX fixed
	pedantic cast warning.
	Corrected support for building with -DTCL_COMPILE_STATS.
	Added efficiency check of object equality.

2000-08-29  Eric Melski  <ericm@ajubasolutions.com>

	* generic/tclStringObj.c: Applied patch from Gerhard Hintermayer
	to provide a more conservative string growth algorithm for strings
	larger than one megabyte; this allows more efficient use of memory
	for very large strings.

2000-08-25  Eric Melski  <ericm@ajubasolutions.com>

	* tests/trace.test: Extended array tracing tests.

	* doc/trace.n: Clarified information about when array traces will
	be fired.

	* generic/tclVar.c (Tcl_ArrayObjCmd): Corrected call to CallTraces
	(for TCL_TRACE_ARRAY) to only be called when the variable is
	either an array or is undefined, to ensure that array traces do
	not fire for scalar variables.

2000-08-24  Eric Melski  <ericm@ajubasolutions.com>
	
	* doc/man.macros: Tweaked tab settings for .SO (Standard Options) 
	sections, based on suggestion from Peter Spjuth.

	* unix/configure.in:
	* unix/tcl.m4 (SC_ENABLE_GCC): Remove --enable-gcc option.
	* win/README: Add note about building with Cygwin.
	* win/configure.in: 
	* win/tcl.m4 (SC_ENABLE_GCC): Remove --enable-gcc option.
	Remove quick hack that provided cross compile support for
	windows builds.

2000-08-24  Eric Melski  <ericm@ajubasolutions.com>

	Overall change:  Added support for command rename/delete traces
	and new trace syntax, from patch from Vince Darley.  Added support
	for array traces for variables.  [RFE: 5048, 5967].

	* doc/trace.n: Updated documentation for new syntax; flagged old
	syntax as deprecated; added documentation for command
	rename/delete traces and variable array traces.

	* tests/trace.test: Updated tests for new trace syntax; new tests
	for command rename/delete traces; new tests for array traces.

	* generic/tclVar.c: Support for new trace syntax; support for
	TCL_TRACE_ARRAY.

	* generic/tclStubInit.c:
	* generic/tclDecls.h:
	* generic/tcl.decls: Stub functions for command rename/delete traces.

	* generic/tcl.h: 
	* generic/tclInt.h:
	* generic/tclBasic.c: Support for command traces.

	* generic/tclCmdMZ.c (TclTraceVariableObjCmd): Patched to support
	new [trace] syntax:  
	trace {add|remove|list} {variable|command} name ops command
	Added support for command traces (rename, delete operations).
	Added support for TCL_TRACE_ARRAY at Tcl level (array operation
	for variable traces).
	
2000-08-20  Eric Melski  <ericm@ajubasolutions.com>

	* generic/tclVar.c: Added check for non-arrays for [array statistics]
	command (patch from Mark Patton).

2000-08-19  David Gravereaux <davygrvy@ajubasolutions.com>

	* generic/tclPlatDecls.h: without a previous '#include <windows.h>',
	tclPlatDecls.h can't be parsed due to a missing definition of TCHAR.
	Added a check to include it when not defined.

	***POSSIBLE OBSCURE BUG*** could be caused when the compile flags
	for the core happen to be different than a project who uses these
	publics regarding -D_MBCS and -D_UNICODE.  This added check might
	have to be revisited later with a better understanding of the
	reprocusions.  I think TCHAR should be replaced with it's expansion.

2000-08-18  David Gravereaux <davygrvy@ajubasolutions.com>

	* win/.cvsignore (added): provides a cleaner build environment with
	graphical CVS clients.

2000-08-15  Eric Melski  <ericm@ajubasolutions.com>

	* library/tcltest1.0/tcltest.tcl: Set debug level in
	tcltest::restoreState to 2, for consistancy with the debug level
	in tcltest::saveState [Bug: 4505].

2000-08-14  Eric Melski  <ericm@ajubasolutions.com>

	* win/makefile.vc: 
	* win/Makefile.in: 
	* unix/Makefile.in: Added tclPlatDecls.h to the list of installed
	headers, for more complete stubs support. [Bug: 5241].

	* generic/tcl.h: Added #include "tclPlatDecls.h" to get
	platform-specific stubs declarations (Tcl_WinTCharToUtf, etc)
	[Bug: 5241].

	* README: Updated link for instructions on compiling Tcl from
	sources to point to correct location
	(http://dev.scriptics.com/doc/... instead of
	http://dev.scriptics.com/support/...).

2000-08-11  Eric Melski  <ericm@ajubasolutions.com>

	* generic/tclEnv.c (TclUnsetEnv): Changed declaration of length
	variable from "unsigned int" to "int", to match usage when passed
	to TclpFindVariable [Bug: 6126].

2000-08-10  Eric Melski  <ericm@ajubasolutions.com>

	* library/msgcat1.0/pkgIndex.tcl: Bumped version number to 1.2
	[Bug: 6100].

	* library/msgcat1.0/msgcat.tcl: Removed erroneous [package forget]
	in msgcat namespace initializer.  Bumped version number to 1.2
	[Bug: 6100].

2000-08-10  David Gravereaux <davygrvy@ajubasolutions.com>

	* generic/tclObj.c: r1.15 accidentally changed a global mutex
	name tclObjMutex to ObjMutex.  Put the correct name back.

2000-08-07  Eric Melski  <ericm@ajubasolutions.com>

	* tests/indexObj.test: Added tests using the [testwrongnumargs]
	command to test Tcl_WrongNumArgs.

	* generic/tclTest.c (TestWrongNumArgsObjCmd): Added test function
	for the Tcl_WrongNumArgs function.

	* generic/tclIndexObj.c (Tcl_WrongNumArgs): Corrected algorithm to
	not insert a space before the message component when objc == 0
	[Bug: 6078].

2000-07-27  Mo DeJong  <mdejong@redhat.com>

	* win/configure.in: TCL_STUB_LIB_FLAG should not
	include ${TCL_DBGX} in win/tclConfig.sh, fix that.

	notifier alerting on all platforms as it was only working on Win
	before.  Removed older Win hacks that would end-up waking the
	wrong notifier in the presence of a threaded build.  All tests
	pass as before.  New test cases will be added soon for the new
	behavior.  [BUG: 5791]

2000-07-25  Eric Melski  <ericm@ajubasolutions.com>

	* generic/tclVar.c (CallTraces): Added check for VAR_TRACE_ACTIVE
	on the array containing the variable before executing traces on
	that array, to conform with normal variable traces and the
	documentation, which states that while executing a trace, other
	traces on that variable are disabled. [Bug: 6049].

	* win/tclWinPipe.c (BuildCommandLine): Added Tcl_DStringFree call
	to prevent potential memory leaks [Bug: 6041].

2000-07-21  Mo DeJong  <mdejong@redhat.com>

	* win/configure.in: Define ${prefix} and ${exec_prefix} like
	unix/configure.in.  Fix or add TCL_SRC_DIR, TCL_STUB_LIB_FILE,
	TCL_STUB_LIB_FLAG, TCL_BUILD_STUB_LIB_SPEC, TCL_STUB_LIB_SPEC,

	* tests/pkgMkIndex.test: Added tests for pkg_compareExtension.

	* library/package.tcl: Enhanced pkg_compareExtension to handle
	Unixes which tack the version number on to the end of library
	names (eg, foo.so.1.2); such filenames will be correctly matched.
	(Patch from Vince Darley).

	* win/makefile.vc: Applied patch from Don Porter to provide better
	nmake support for NT/Alpha [RFE: 5938].

2000-07-18  Mo DeJong  <mdejong@redhat.com>

	* unix/configure.in:
	* unix/tcl.m4:
	* win/tcl.m4: Properly quote arguments to m4 macros. This allows
	Tcl to work with the new version of autoconf.

2000-07-18  Eric Melski  <ericm@ajubasolutions.com>

	* tests/opt.test: Removed references to Lfirst, Lrest functions.

	* library/opt0.4/optparse.tcl: Applied patch from Chris Nelson,
	which replaces the [Lfirst] function with an inline [lindex ... 0]
	and [Lrest] with [lrange ... 1 end], for better performance. 
	[RFE: 6019]
	

2000-07-18  Eric Melski  <ericm@scriptics.com>

	* compat/string.h: Fixed function prototypes for strpbrk and
	strtok [Bug: 6020].

2000-07-17  David Gravereaux  <davygrvy@ajubasolutions.com>

	* win/tclWinChan.c: Win2K OS bug with
	GetStdHandle(STD_OUTPUT_HANDLE)	giving the wrong answer.  This
	made TclpGetDefaultStdChannel grab what it thought was a valid
	native stdout handle.  Added a new WriteFile() test to	make sure
	it's really valid.  This OS bug doesn't affect the shells.  Only
	-subsystem:windows (aka WinMain) application that dynamically
	load tclXX.dll [BUG: 5971]

2000-07-17  Eric Melski  <ericm@scriptics.com>

	* library/msgcat1.0/msgcat.tcl: 
	* doc/msgcat.n: 
	* tests/msgcat.test: Applied patches from Chris Nelson, to provide
	the mcmset function, which allows the translator to set multiple
	string translations in a single function call, rather than
	requiring many calls to mcset. [RFE: 6000, 5993].  In addition,
	these patches correct mcload to use utf-8 encoding on when reading
	message catalog files, and provides for better default behavior
	for determining the locale on a Windows system.

2000-07-17  Mo DeJong  <mdejong@redhat.com>

	* unix/tcl.m4 (SC_ENABLE_GCC): Don't set CC=gcc

	* tests/set-old.test:
	* doc/unset.n:
	* generic/tclVar.c (Tcl_UnsetObjCmd): added -nocomplain and --
	options to unset, to allow for a silent unset operation.

2000-05-31  Eric Melski  <ericm@scriptics.com>

	* generic/tclVar.c (Tcl_ArrayObjCmd): Added support for regexp and
	exact matching for [array names] command. [RFE: 3684].

	* doc/array.n: Added documentation for [array names
	-exact/-regexp/-glob] [RFE: 3684].

	* tests/set-old.test: Added tests for [array names
	-exact/-regexp/-glob] [RFE: 3684].

2000-06-06  Jeff Hobbs  <hobbs@scriptics.com>

	8.4a1 RELEASE

	* generic/tclExecute.c (TclExecuteByteCode INST_STR_CMP): added
	test of iResult return from memcmp, as memcmp isn't required to
	return only -1,0,1.

2000-06-03  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): Corrected
	caching of the index ptr to account for offsets != sizeof(char *).
	[Bug: 5153]

2000-05-29  Sandeep Tamhankar <sandeep@scriptics.com>

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

2000-05-27  Jeff Hobbs  <hobbs@scriptics.com>

	* tests/info.test:
	* doc/info.n:
	* generic/tclIOUtil.c (Tcl_EvalFile):
	* generic/tclCmdIL.c (InfoScriptCmd): added ability to set the

	be beneficial for virtual file system programs. [Bug: 4225]

2000-05-26  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclCmdMZ.c (Tcl_RegsubObjCmd): reworked to operate in

	Removed inneffectual STR_RANGE "special" ByteArray support.
	Optimized STR_MAP algorithm, especially optimized for one-pair case.
	Fixed possible mem overrun in STR_INDEX bytearray case.
	
	* generic/tclCompExpr.c: changed INST_STREQ -> INST_STR_EQ,
	INST_STRNEQ -> INST_STR_NEQ
	* generic/tclCompile.c: added streq, strneq, strcmp, strlen &
	strmatch to the compiled stats instructionTable
	* generic/tclCompile.h: added instructions INST_STR_CMP,
	INST_STR_INDEX, INST_STR_MATCH
	* generic/tclCompCmds.c: added byte compiler support for
	[string compare|match|index].
	* generic/tclExecute.c:
	Changed INST_STR_(N)EQ to return an Int object and not bother
	trying to reuse the top stack object.
	Added INST_STR_CMP, INST_STR_INDEX, INST_STR_MATCH bytecode ops.
	Extended evalstats output info with Tcl_IsShared stat info.

	* generic/tclInt.h:
	* generic/tclObj.c (Tcl_DbIsShared): added support for checking
	result of Tcl_IsShared in evalstats (TCL_COMPILE_STATS).

	* generic/tclStringObj.c (Tcl_AppendUnicodeToObj): removed dead code.
	(AppendUnicodeToUnicodeRep) removed overallocation by extra
	sizeof(Tcl_UniChar) multiplier.

2000-05-23  Eric Melski  <ericm@scriptics.com>

	* generic/tclInt.h: Added function prototypes for
	TclCompileStringCmd and TclCompileReturnCmd.

	* generic/tclCompile.h: Added definition of INST_STRLEN opcode and
	updated LAST_INST_OPCODE value.

	* generic/tclBasic.c: Added information about TclCompileStringCmd
	and TclCompileReturnCmd to BuiltInCmds table.

	* generic/tclExecute.c (TclExecuteByteCode): Added support for the
	INST_STRLEN opcode.

	* generic/tclCompCmds.c 
	(TclCompileStringCmd): Basic implementation of byte-compiled
	[string] command.  Not all subcommands are implemented; those
	that are not an out-line compiled.

	(TclCompileReturnCmd): Byte-compiled implementation of [return]
	command.  Only "simple" returns are byte-compiled; in particular,
	if the -code, -errorinfo or -errorcode flags are used, the command
	is not byte-compiled.

2000-05-02  Andreas Kupries <a.kupries@westend.com>

	* Overall changes:
	  (1) Implementation of joinable threads for all platforms.
	  (2) Additional API's for channels. Required to allow the
	  thread extension to move channels between threads.

	* generic/tcl.decls (lines 1360f): Added Tcl_JoinThread,
	  Tcl_IsChannelShared, Tcl_IsChannelRegistered, Tcl_CutChannel,
	  Tcl_SpliceChannel, Tcl_IsChannelExisting and
	  Tcl_ClearChannelHandlers (slots 394 to 400).

	* generic/tclIO.c: Implemented Tcl_IsChannelRegistered,
 	  Tcl_IsChannelShared, Tcl_CutChannel, Tcl_SpliceChannel,
 	  Tcl_IsChannelExisting and Tcl_ClearChannelHandlers.
	  Tcl_CutChannel uses code from CloseChannel. Replaced this code
 	  by a call to Tcl_CutChannel.  Replaced several code fragments
 	  adding channels to the channel list with calls to
 	  Tcl_SpliceChannel. Removed now unused variables from
 	  CloseChannel and Tcl_UnstackChannel.  Tcl_ClearChannelHandlers
 	  uses code from Tcl_Close. Replaced this code by a call to
 	  Tcl_ClearChannelHandlers. Removed now unused variables from
 	  Tcl_Close. Added the subcommands 'cut', 'forgetch', 'splice' and
 	  'isshared' to the test code
	  (TclTestChannelCmd).

	* unix/tclUnixThread.c: Implemented Tcl_JoinThread using the
	  pthread-functionality.

	* win/tclWinThrd.c: Fixed several small typos in comments.
	  Implemented Tcl_JoinThread using a platform independent
	  emulation layer (see generic/tclThreadJoin.c below). Added
	  'joinLock' to serialize Tcl_CreateThread and TclpExitThread to
	  prevent a race for joinable threads.

	* mac/tclMacThrd.c: Implemented Tcl_JoinThread using a platform
	  independent emulation layer (see generic/tclThreadJoin.c
	  below). Due to the cooperative nature of threading on this
	  platform the race mentioned above is not present.

	* generic/tclThreadJoin.c: New file. Contains a platform
	  independent emulation layer helping in the implementation of
	  joinable threads for the win and mac platforms.

	* generic/tclInt.h: Added declarations for TclJoinThread,
	  TclRememberJoinableThread and TclSignalExitThread. These
	  procedures define the API of the emulation layer for joinable
	  threads (see generic/tclThreadJoin.c above).

	* win/Makefile.in:
	* win/makefile.vc: Added generic/tclTheadJoin.o to the rules.

	* mac/: I don't know to which file generic/tclTheadJoin.o has to
	  be added to so that it compiles. Sorry.

	* unix/tclUnixChan.c: #ifdef'd the thread-local list of file
 	  channels as it prevents us from transfering channels. To restore
 	  this we may need an extended interface to drivers in the
 	  future. Target: 9.0. Found while testing the new transfer of
 	  channels. The information in this list for a channel was left
 	  behind and then crashed the system during finalization.

	* generic/tclThreadTest.c: Added -joinable flag to 'testthread
	  create'. Added subcommand 'testthread join'.

	* doc/CrtChannel.3: Added documentation for Tcl_IsChannelRegistered,
 	  Tcl_IsChannelShared, Tcl_CutChannel, Tcl_SpliceChannel,
	  Tcl_IsChannelExisting and Tcl_ClearChannelHandlers.

	* doc/Thread.3: Added documentation for Tcl_JoinThread.

	* tests/thread.test: Added tests for joining of threads.

2000-04-27  Eric Melski  <ericm@scriptics.com>

2000-04-26  Eric Melski  <ericm@scriptics.com>

	* doc/memory.n: Man page for Tcl "memory" command, which is
	created when TCL_MEM_DEBUG is defined at compile time.

	* doc/TCL_MEM_DEBUG.3: Man page with overall information about
	TCL_MEM_DEBUG usage.

	* doc/DumpActiveMemory.3: Man page for Tcl_DumpActiveMemory,
	Tcl_InitMemory, and Tcl_ValidateAllMemory [Bug: 1816, 1835].

	* generic/tclCkalloc.c: Fixed some function headers.

	* unix/mkLinks: Regen'd with new mkLinks.tcl.

	* unix/mkLinks.tcl: Fixed indentation, made link setup more
	intelligent (only do one existance test per man page, instead of
	one per function).

	* doc/library.n: Fixed .SH NAME macro to include each function
	documented on the page, so that mkLinks will know about the
	functions listed there, and so that the Windows help file index
	will get set up correctly [Bug: 1898, 5273].

	* unix/tclUnixNotfy.c (Tcl_FinalizeNotifier, NotifierThreadProc):
	added write of 'q' into triggerPipe for notifier in threaded case,
	so that Tcl doesn't hang when children are still running [Bug: 4139]

	* unix/tclUnixThrd.c (Tcl_MutexLock): minor comment fixes.

2000-04-23  Jim Ingham  <jingham@cygnus.com>

	These changes make some error handling marginally better for Mac
	sockets.  It is still somewhat flakey, however.

	* mac/tclMacSock.c (TcpClose): Add timeouts to the close - these
	don't seem to be honored, however.
	Use a separate PB for the release, since an async connect socket
	will still be using the original buffer.
	Make sure TCPRelease returns noErr before freeing the recvBuff.
	If the call returns an error, then the buffer is not right.
	* mac/tclMacSock.c (CreateSocket): Add timeouts to the async
	create. These don't seem to trigger, however.  Sigh...
	* mac/tclMacSock.c (WaitForSocketEvent): If an TCP_ASYNC_CONNECT
	socket errors out, then return EWOULDBLOCK & error out.
	* mac/tclMacSock.c (NotifyRoutine): Added a NotifyRoutine for
	experimenting with MacTCP.

2000-04-22  Jim Ingham <jingham@cygnus.com>

	* library/package.tcl (tclPkgUnknown): Fixed a typo in the Mac package
	search part of tclPkgUnknown.

2000-04-21  Sandeep Tamhankar <sandeep@scriptics.com>

	* library/http2.1/http.tcl: Fixed a newly introduced bug where if
	there's a -command callback and something goes wrong, geturl threw
	an exception, called the callback, and unset the token.  I changed
	it so that it will not call the callback when throwing an
	exception (so the caller only finds out about a given error from
	one place).  Also, fixed http::ncode so that it actually gives you
	back the http return code (i.e. 200, 404, etc.) instead of the
	first digit of the version of HTTP being used (i.e. 1).

2000-04-21  Brent Welch <welch@scriptics.com>

	* library/http2.1/http.tcl: More thrashing with the "server closes
	without reading post data" scenario.  Reverted to the previous
	filevent configuratiuon, which seems to work better with small
	amounts of post data.  

2000-04-20  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclAlloc.c: wrapped caddr_t define to not be done on Unix
	* unix/tclUnixPort.h: added Tclp*Alloc defines to allow the use of
	USE_TCLALLOC on Unix. [Bug: 4731]

	* library/dde1.1/pkgIndex.tcl:
	* library/reg1.0/pkgIndex.tcl:
	* win/tclWinChan.c:

	* win/Makefile.in: expanded cleanup target for help files

	* doc/Thread.3: minor macro cleanup

	* win/tclWinPipe.c: Added "CONST" keyword to declaration of char

2000-04-09  Brent Welch <welch@scriptics.com>

	* lib/httpd2.1/http.tcl: Worked on the "server closes before
	reading post data" case, which unfortunately causes different
	error cases on Solaris, which can read the reply, and Linux
	and Windows, which cannot read anything.  This is all in the
	loop-back case - client and server on the same host.  Also
	unified the error handling so the "ioerror" status goes away
	and errors are reflected in a more uniform way. Updated the
	man page to document the behavior.

2000-04-09  Jeff Hobbs  <hobbs@scriptics.com>

	* tests/reg.test (matchexpected): corrected tests to use tcltest
	constraint types to skip certain tests.

	* generic/tclBasic.c (Tcl_SetCommandInfo): comment fix

	* unix/tclUnixThrd.c (Tcl_CreateThread): moved TCL_THREADS ifdef
	inside of func as it is declared for non-threads builds as well.
	In the non-threads case, it always returns TCL_ERROR (couldn't
	create thread).

2000-04-08  Andreas Kupries <a.kupries@westend.com>

	* Overall change: Definition of a public API for the creation of
	  new threads.

	* generic/tclInt.h (line 1802f): Removed the definition of
	'TclpThreadCreate'. (line 793f) Removed the definition of
	'Tcl_ThreadCreateProc'.

	* generic/tcl.h (line 388f): Readded the definition of
	  'Tcl_ThreadCreateProc'. Added Win32 stuff send in by David
	  Graveraux <davygrvy@bigfoot.com> to that too (__stdcall,
	  ...). Added macros for the default stacksize and allowed flags.

	* generic/tcl.decls (line 1356f): Added definition of
	  'Tcl_CreateThread', slot 393 of the stub table. Two new
	  arguments in the public API, for stacksize and flags.

	* win/tclWinThrd.c:
	* mac/tclMacThrd.c: Renamed TclpThreadCreate to Tcl_CreateThread,
	  added handling of the stacksize. Flags are currently ignored.

	* unix/tclUnixThrd.c: See above, but handles joinable
	  flag. Ignores the specified stacksize if the macro
	  HAVE_PTHREAD_ATTR_SETSTACKSIZE is not defined.

	* generic/tclThreadTest.c (line 363): See below.

	* unix/tclUnixNotfy.c (line 210): Adapted to the changes
	  above. Uses default stacksize and no flags now.

	* unic/tcl.m4 (line 382f): Added a check for
	  'pthread_attr_setstacksize' to detect platforms not implementing
	  this feature of pthreads. If it is implemented, configure will
	  define the macro HAVE_PTHREAD_ATTR_SETSTACKSIZE (See
	  unix/tclUnixThrd.c too).

	* doc/Thread.3: Added Tcl_CreateThread and its arguments to the
	  list of described functions. Removed stuff about not providing a
	  public C-API for thread-creation.

2000-04-07  Jeff Hobbs  <hobbs@scriptics.com>

	* doc/binary.n: clarified docs on sign extension in binary scan
	[Bug: 3466]

	* library/tcltest1.0/tcltest.tcl (initConstraints): removed win32s
	references (no longer supported)

	* tests/fCmd.test: marked test 8.1 knownBug because it is
	dangerous on poorly configured systems [Bug: 3881]
	and added 8.2 to keep essence of 8.1 tested.

2000-04-05  Andreas Kupries <a.kupries@westend.com>

	* generic/tclIO.c (Tcl_UnstackChannel, line 1831): Forcing
	interest mask to the correct value after an unstack and
	re-initialization of the notifier via the watchProc. Without this
	the first fileevent after an unstack will come through and be
	processed, but no more. [Bug: ??].

2000-03-04  Brent Welch  <welch@scriptics.com>

	* {win,unix}/Makefile.in: added dependency of tclStubInit.c on
	tcl.decls and tclInt.decls
	* generic/tclThread.c: Tweak so this compiles w/out TCL_THREADS
	* generic/{tcl.decls,tclStubInit.c}:  Just touched the tcl.decls and
	regenerated the tclStubInit.c file

2000-03-29  Sandeep Tamhankar <sandeep@scriptics.com>

	* library/http2.1/http.tcl: For the -querychannel option,
	fconfigure the socket to be binary so that we don't translate
	anything while reading the data.  This is because we determine the
	content length of the data on the channel by using seek (to the end
	of the file) and tell on the file handle, and we need the
	content-length to match the amount of data actually sent, and
	translation can affect the number of bytes posted.

2000-04-03  Andreas Kupries <a.kupries@westend.com>

	* Overall change: Definition of public API's for the finalization
	of conditions and mutexes. [Bug: 4199].

	* generic/tclInt.h: Removed definitions of TclFinalizeMutex and
	TclFinalizeCondition.

	* generic/tcl.decls: Added declarations of Tcl_MutexFinalize and
	Tcl_ConditionFinalize.

	* generic/tclThread.c: Renamed TclFinalizeMutex to
	Tcl_MutexFinalize. Renamed TclFinalizeCondition to
	Tcl_ConditionFinalize.

	* generic/tclNotify.c: Changed usage of TclFinalizeMutex to
	Tcl_MutexFinalize.

	* unix/tclUnixNotfy.c: 
	* generic/tclThreadTest.c: Changed usages of TclFinalizeCondition to
	Tcl_ConditionFinalize.

	* generic/tcl.h: Added empty macros for Tcl_MutexFinalize and
	Tcl_ConditionFinalize, to be used when the core is compiled
	without threads. 

	* doc/Thread.3:	Added description the new API's.

2000-04-03  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclCmdIL.c (InfoVarsCmd): checked for non-NULL procPtr
	to prevent itcl info override crash [Bug: 4064]

	* tests/foreach.test:
	* tests/namespace.test:
	* tests/var.test: Added lsorts to avoid random sorted return
	problems. [Bug: 2682]

	* tests/fileName.test: fixed 14.1 test fragility [Bug: 1482]

	* tools/man2help2.tcl: fixed winhelp cross-linking error [Bug: 4156]
	improved translation to winhelp [Bug: 3679]

	* unix/Makefile.in (MAN_INSTALL_DIR): patch to accept --mandir
	correctly [Bug: 4085]

	* unix/dltest/pkg[a-e].c: Cleaned up test packages [Bug: 2293]

2000-04-03  Eric Melski  <ericm@scriptics.com>

	* unix/tclUnixFCmd.c (SetGroupAttribute): 
	* unix/tclUnixFCmd.c (SetOwnerAttribute): Added (uid_t) and (gid_t) 
	casts to avoid compiler warnings.

2000-03-31  Eric Melski  <ericm@scriptics.com>

	* generic/tclGet.c (Tcl_GetDouble): Added additional conditions to
	error test (previously only errno was checked, but the return
	value of strtod() should be checked as well).  [Bug: 4118].

	* tests/exec.test: Added test for proper conversion of UTF data
	when used with "<< $dataWithUTF" on exec's.

	* unix/tclUnixPipe.c (TclpCreateTempFile): Added
	Tcl_UtfToExternalDString call, so that if there is UTF content in
	the string it will be properly converted to the system encoding
	before being written [Bug: 4030].
	(TclpCreateTempFile): Added a check on the return value of tmpnam;
	some systems (Linux, for example) will start to return NULL after
	tmpnam has been called TMP_MAX times; not checking for this can
	have bad results (overwriting temp files, core dumps, etc.)

2000-03-30  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken): Added comments
	noting the need to pair ckalloc with ckfree. [Bug: 4262]

	* generic/tclInt.decls:
	* generic/tclIntPlatDecls.h:
	* generic/tclStubInit.c:
	* win/tclWin32Dll.c: removed TclWinSynchSpawn (vestige of Win32s
	support).

	* win/tclWinReg.c: made use of TclWinGetPlatformId instead of
	getting info again

	* win/tclWinPort.h:
	* win/Makefile.in:
	* win/configure.in:
	* win/tcl.m4: Added support for gcc/mingw on Windows [Bug: 4234]

2000-03-29  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclCompile.c (TclCleanupByteCode): made ByteCode cleanup
	more aware of TCL_BYTECODE_PRECOMPILED flagged structs (gen'd by
	tbcload), to correctly clean them up.

	* generic/tclClock.c (FormatClock): moved check for empty format
	earlier, commented 0 result return value

2000-03-29  Sandeep Tamhankar <sandeep@scriptics.com>

	* library/http2.1/http.tcl: Removed an unnecessary fileevent
	statement from the error processing part of the Write method.
	Also, fixed two potential memory leaks in wait and reset, in which
	the state array wasn't being unset before throwing an exception.
	Prior to this version, Brent checked in a fix to catch a
	fileevent statement that was sometimes causing a stack trace when
	geturl was called with -timeout.  I believe Brent's fix is
	necessary because TLS closes bad sockets for secure connections,
	and the fileevent was trying to act on a socket that no longer
	existed.

2000-03-27  Jeff Hobbs  <hobbs@scriptics.com>

	* tests/httpd: removed unnecessary 'puts stderr "Post Dispatch"'

	* tests/namespace.test:
	* generic/tclNamesp.c (Tcl_Export): added a uniq'ing test to the
	export list so only one instance of each export pattern would
	exist in the list.

	* generic/tclExecute.c (TclExecuteByteCode): optimized case for
	the empty string in ==/!= comparisons

2000-03-27  Eric Melski  <ericm@scriptics.com>

	* unix/tclUnixChan.c: Added (off_t) type casts in lseek() call
	[Bug: 4409].

	* unix/tclLoadAout.c: 
	* unix/tclUnixPipe.c: Added (off_t) type casts in lseek() calls
	[Bug: 4410].

2000-03-22  Sandeep Tamhankar <sandeep@scriptics.com>

	* library/http2.1/http.tcl: Fixed a bug where string query data
	that was bigger than queryblocksize would get duplicate characters
	at block boundaries.

2000-03-22  Sandeep Tamhankar <sandeep@scriptics.com>

	* library/http2.1/http.tcl: Fixed bug 4463, where we were getting
	a stack trace if we tried to publish a project to a good host but
	a port where there was no server listening.  It turned out the
	problem was a stray fileevent that needed to be cleared.  Also,
	fixed a bug where http::code could stack trace if called on a bad
	token (one which didn't represent a successful geturl) by adding
	an http element to the state array in geturl.

2000-03-21  Eric Melski  <ericm@scriptics.com>

	* tests/clock.test: Modified some tests that were not robust with
	respect to the time zone in which they were run and were thus
	failing.

	* doc/clock.n: Clarified meaning of -gmt with respect to -base
	when used with [clock scan] (-gmt does not affect the
	interpretation of -base).

2000-03-19  Sandeep Tamhankar <sandeep@scriptics.com>

	* library/http2.1/http.tcl: geturl used to throw an exception when
	the connection failed; I accidentally returned a token with the
	error info, breaking backwards compatibility.  I changed it back
	to throwing an exception, but unsetting the state array first
	(thus still eliminating the original memory leak problem).

2000-03-19  Sandeep Tamhankar <sandeep@scriptics.com>

	* library/http2.1/http.tcl: Added -querychannel option and altered
	some of Brent's modifications to allow asynchronous posts (via
	-command).  Also modified -queryprogress so that it calls the
	query callback as <callback> <token> <total size> <current size>
	to be consistent with -progress.  Added -queryblocksize option
	with default 8192 bytes for post blocksize.  Fixed a bunch of
	potential memory leaks for the case when geturl receives bad args
	or can't open a socket, etc.  Overall, the package really rocks
	now.

	* doc/http.n: Added -queryblocksize, -querychannel, and
	-queryprogress.  Also, changed the description of -blocksize,
	which states that the -progress callback will be called for each
	block, to now qualify that with an "if -progress is specified".

	* tests/http.test: Added a querychannel test for synchronous and
	asynchronous posts, altered the queryprogress test such that the
	callback conforms to the -progress format.  Also, had to use the
	-queryblocksize option to do the post 16K at a time to match
	Brent's expected results (and to test that -queryblocksize works).

2000-03-15  Brent Welch <welch@scriptics.com>

	* library/http2.1/http.tcl: Added -queryprogress callback to
	http::geturl and also changed it so that writing the post data
	is event driven if the queryprogress callback or a timeout is given.
	This allows a timeout to occur when writing lots of post data.
	The queryprogress callback is called after each block of query
	data is posted.  It has the same signature as the -progress callback.

2000-03-06  Eric Melski  <ericm@scriptics.com>

	* library/package.tcl: Applied patch from Bug: 2570; rather than
	setting geometry of slave interp to 0x0 when Tk was loaded, it now
	does "wm withdraw .".  Both remove the main window from the
	display, but the former caused some internal structures to get
	initialized to zero, which caused crashes with some extensions.

2000-03-02  Jeff Hobbs  <hobbs@scriptics.com>

	* library/package.tcl (tclPkgUnknown): extended to allow
	recognizes changes in the auto_path while sourcing in other
	pkgIndex.tcl files

	* doc/FindExec.3: fixed doc for declaration of Tcl_FindExecutable
	[Bug: 4275]

	* generic/tclFileName.c (Tcl_TranslateFileName): Applied patch
	from Newman to significantly speedup file split/join on Windows
	(replaces regexp with custom parser).  [Bug: 2867]

	* win/README.binary: change mailing lists from @consortium.org
	to @scriptics.com [Bug: 4173]

2000-02-28  Eric Melski  <ericm@scriptics.com>

	* tests/clock.test: Added test for ISO bases < 100000

	* generic/tclDate.c: (generated on Solaris)
	* generic/tclGetDate.y: Changed condition for deciding if a number
	is an ISO 8601 base from number >= 100000 to numberOfDigits >= 6.
	Previously it would fail to recognize 000000 as an ISO base.

2000-02-14  Eric Melski  <ericm@scriptics.com>

	* unix/Makefile.in: Added rpm target to generate Tcl binary RPM.

	* unix/tcl.spec: RPM specification file for a Tcl binary RPM for
	Linux.

2000-02-10  Jeff Hobbs  <hobbs@scriptics.com>

	* changes: updated for 8.3.0 release

	* doc/load.n: added notes about dll load errors on Windows

	* unix/README:
	* unix/Makefile.in (dist): removed porting.notes and porting.old
	from distribution and CVS.  The information was very outdated.  Now
	refer to http://dev.scriptics.com/services/support/platforms.html

	* tests/unixInit.test: fixed japanese LANG encoding test [Bug: 3549]

	* unix/configure.in:
	* unix/tcl.m4: correct CFLAG_WARNING setting,
	fixed gcc config for AIX,
	added -export-dynamic to LDFLAGS for FreeBSD-3+ [Bug: 2998]

	* win/tclWinLoad.c (TclpLoadFile): improved error message for load
	failures, could perhaps be even more intelligent.

2000-02-09  Jim Ingham	 <jingham@cygnus.com>

	* mac/tclMacSock.c: Don't panic when you get an error closing an async 
	socket.	 This doesn't seem to hurt anything, and we return the error so
	the caller can do the right thing.

	New Files:
	* mac/MW_TclHeader.h:
	* mac/MW_TclTestHeader.h:
	* mac/MW_TclTestHeader.pch:
	* mac/MW_TclAppleScriptHeader.h: More convenient to use .h prefix files
	in the preference panels...

	The above are curtesy of Daniel Steffen (steffen@math.mq.edu.au)

2000-02-08  Eric Melski  <ericm@scriptics.com>

	* tests/clock.test: Added tests for "next monthname" constructs.
	* generic/tclDate.c: 
	* generic/tclGetDate.y (Message): Added a grammar rule for "next
	monthname" so that we can handle "next january" and similar
	constructs (bug #4146).

2000-02-08  Jeff Hobbs  <hobbs@scriptics.com>

	list to allow dirnames with spaces

	* unix/tcl.m4: changed all -fpic to -fPIC

	* generic/tclDecls.h:
	* generic/tcl.decls: change Tcl_GetOpenFile to use decl of 'int
	forWriting' instead of 'int write' to avoid shadowing [Bug: 4121]

	* tests/httpold.test: changed test script to source in the httpd
	server procs from httpd instead of having its own set.

	* tests/httpd: improved query support in test httpd to handle fix
	in http.tcl. [Bug: 4089 change 2000-02-01]

	* unix/README: fixed notes about --enable-shared and add note
	about --disable-shared.

2000-02-07  Eric Melski  <ericm@scriptics.com>

	* tests/package.test: 
	* library/tclIndex: 
	* library/package.tcl: Renamed ::package namespace to ::pkg.

2000-02-03  Eric Melski <ericm@scriptics.com>

	* doc/Package.n:
	* doc/packagens.n: Renamed Package.n -> packagens.n because Windows 
	can't deal with case-sensitive names.

2000-02-02  Jeff Hobbs  <hobbs@scriptics.com>

	* tests/regexp.test: added tests for -all and -inline switches
	* doc/regexp.n: added docs for -all and -inline switches
	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd): added extra comments for
	new -all and -inline switches to regexp command

2000-02-01  Eric Melski  <ericm@scriptics.com>

	* library/init.tcl: Applied patch from rfe 1734 regarding
	auto_load errors not setting error message and errorInfo properly.

2000-02-01  Jeff Hobbs  <hobbs@scriptics.com>

	* win/Makefile.in (install-*): reduced verbosity of install

	* generic/tclFileName.c (Tcl_JoinPath): improved support for special
	QNX node id prefixes in pathnames [Bug: 4053]

	* library/http1.0/http.tcl:
	* library/http2.1/http.tcl: The query data POSTed was newline
	terminated when it shouldn't be altered [Bug: 4089]

2000-01-31  Eric Melski  <ericm@scriptics.com>

	* tests/package.test: 
	* library/tclIndex: 
	* library/package.tcl: Added ::package namespace and
	::package::create function.

	* library/init.tcl: Fixed problem with auto_load and determining
	if commands were loaded.

	* library/auto.tcl: "Fixed" issues with $ in files to be auto indexed.

	* doc/Package.n: New man page for package::create function.

	* doc/pkgMkIndex.n: Added additional information.

	* doc/library.n: Added additional qualification regarding auto_mkindex.

2000-01-28  Eric Melski  <ericm@scriptics.com>

	* tests/pkg/magicchar2.tcl: 
	* tests/autoMkindex.test: Test for auto loader fix (bug #2480).

	* library/init.tcl: auto_load was using [info commands $name] to
	determine if a given command was available; if the command name
	had * or [] it, this would fail because info commands uses
	glob-style matching.  This is fixed.  (Bug #2480).

	* tests/pkg/spacename.tcl: 
	* tests/pkgMkIndex.test: Tests for fix for bug #2360.

	* library/package.tcl: Fixed to extract only the first element of
	the list returned by auto_qualify (bug #2360).

	* tests/pkg/magicchar.tcl: 
	* tests/autoMkindex.test: Test for fix for bug #2611.

	* library/auto.tcl: Fixed the regular expression that performs $
	escaping before sourcing a file to index.  It was erroneously
	adding \ escapes even to $'s that were already escaped,
	effectively "un-escaping" those $'s.  (bug #2611).

2000-01-27  Eric Melski  <ericm@scriptics.com>

	* tests/autoMkindex.test: 
	* library/auto.tcl: Applied patch (with slight modification) from
	bug #2701:  auto_mkIndex uses platform dependent file paths.
	Added test for fix.

2000-01-27  Jennifer Hom  <jenn@scriptics.com>

	* library/tcltest1.0/tcltest.tcl: Changed NormalizePath to
	normalizePath and exported it as a public proc.  This proc 
	creates an absolute path given the name of the variable containing
	the path to modify.  The path is modified in place.
	* library/tcltest1.0/pkgIndex.tcl: Added normalizePath.
	* tests/all.tcl: Changed code to use normalizePath.

2000-01-27  Eric Melski  <ericm@scriptics.com>

	* tests/pkg/samename.tcl: test file for bug #1983
	
	* tests/pkgMkIndex.test: 
	* doc/pkgMkIndex.n: 
	* library/package.tcl: Per rfe #4097, optimized creation of direct
	load packages to bypass computing the list of commands added by
	the new package.  Also made direct loading the default, and added
	a -lazy option.
	Fixed bug #1983, dealing with pkg_mkIndex incorrectly handling
	situations with two procs by the same name but in different
	namespaces (ie, foo::baz and bar::baz).

2000-01-26  Eric Melski  <ericm@scriptics.com>

	* generic/tclNamesp.c: Undid fix for #956, which broke backwards
	compatibility.

	* doc/variable.n: 
	* doc/trace.n: 
	* doc/namespace.n: 
	* doc/info.n: Added further information about differences between
	"namespace which" and "info exists".

	* doc/SetErrno.3: Added descriptions of ErrnoId() and ErrnoMsg()
	functions.

2000-01-25  Jeff Hobbs  <hobbs@scriptics.com>

	* unix/tcl.m4: modified EXTRA_CFLAGS to add -DHAVE_TZSET for
	OSF1-V* and ULTRIX-4.* when not using gcc.  Also added higher min
	stack size for OSF1-V* when building with threads. [Bug: 4063]

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

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): fixed potential leak
	when calling lsort -command with bad command [Bug: 4067]

	* generic/tclFileName.c (Tcl_JoinPath): added support for special
	QNX node id prefixes in pathnames [Bug: 4053]

	* doc/ListObj.3: clarified Tcl_ListObjGetElements docs [Bug: 4080]

	* doc/glob.n: clarified Mac path separator determination docs.

	* win/makefile.vc: added some support for building helpfile on Windows

2000-01-23  Jeff Hobbs  <hobbs@scriptics.com>

	* library/init.tcl (auto_execok): added 'start' to list of
	recognized built-in commands for COMSPEC on NT. [Bug: 2858]

	* unix/tclUnixPort.h: moved include of <utime.h> lower since some
	systems (UTS) require sys/types.h to be included first [Bug: 4031]

	* unix/tclUnixChan.c (CreateSocketAddress): changed comparison
	with -1 to 0xFFFFFFFF, to ensure 32 bit comparison even on 64 bit
	systems. [Bug: 3878]

	* generic/tclFileName.c: improved guessing of path separator
	for the Mac. (Darley)

	* generic/tclInt.h:
	* generic/tcl.decls: moved Tcl_ProcObjCmd to stubs table [Bug: 3827]
	and removed 'register' from stub definition of
	Tcl_AppendUnicodeToObj [Bug: 4038]

2000-01-21  Eric Melski  <ericm@scriptics.com>

	* unix/mkLinks: 
	* doc/GetHostName.3: Man page for Tcl_GetHostName (bug #1817).

	* doc/lreplace.n: Corrected man page with respect to treatment of
	empty lists, and "prettied up" the page. (bug #1705).

2000-01-20  Eric Melski  <ericm@scriptics.com>

	* tests/namespace.test: Added test for undefined variables with
	namespace which (bug #956).

	* generic/tclNamesp.c: Added check for undefined variables in
	NamespaceWhichCmd (bug #956).

	* tests/var.test: Added tests for corrected variable behavior 
	(bug #981).

	* doc/upvar.n: Expanded explanation of upvar behavior with respect to
	variable traces.  (bugs 3917 1433 2110).

	* generic/tclVar.c: Changed behavior of variable command when name
	refers to an element in an array (ie, "variable foo(x)") to always
	return an error, regardless of existance of that element in the
	array (now behavior is consistant with docs too) (bug #981).

2000-01-20  Jeff Hobbs  <hobbs@scriptics.com>

	* generic/tclCmdIL.c (InfoBodyCmd): made [info body] return a
	string if the body has been bytecompiled.
	* generic/tclBasic.c (Tcl_EvalObjEx): added pedantic check for
	originating proc body of bytecompiled code, #def'd out as the
	change for [info body] should make it unnecessary

	* unix/tclUnixNotfy.c (Tcl_InitNotifier): added cast for tsdPtr

	* tests/set.test: added test for complex array elem name compiling
	* generic/tclCompCmds.c (TclCompileSetCmd): Fixed parsing of array
	elements during compiling, and slightly optimised same [Bug: 3889]

	* doc/tclvars.n: added definitions for tcl_(non)wordchars

	* doc/vwait.n: added notes about requirement for vwait var being
	globally scoped [Bug: 3329]

	* library/word.tcl: changed tcl_(non)wordchars settings to use
	new unicode regexp char class escapes instead of char sequences

2000-01-14  Eric Melski  <ericm@scriptics.com>

	* tests/var.test: Added a test for the array multiple delete
	protection in Tcl_UnsetVar2.

	* generic/tclVar.c: Added protection in Tcl_UnsetVar2 against
	attempts to multiply delete arrays when unsetting them (bug
	#3453).  This could happen if there was an unset trace on an array
	element and the trace proc made a global or upvar link to the
	array, and then the array was unset at the global level.  See the
	bug reference for more information.

	* unix/tclUnixTime.c: New clock format format.

	* compat/strftime.c: New clock format format.

	* generic/tclGetDate.y: New clock scan format.

	* tests/cmdIL.test: Added tests for lsort -dictionary with
	characters that occur between Z and a in ASCII.

	* generic/tclCmdIL.c: Modified DictionaryCompare function (used by
	lsort -dictionary) to do upper/lower case equivalency before doing
	character comparisons, instead of after.  This fixes bug #1357, in
	which lsort -dictionary [list ` AA c CC] and lsort -dictionary
	[list AA c ` CC] gave different (and both wrong) results.
