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

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

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

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

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

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

        cd $dir
	foreach f [glob *] { # action and/or recursion on $f }
	cd ..

        * generic/tclTest.c: Fix for [Bug 683181] where test suite
	left files in 'tmp'.
	
2003-02-08  Jeff Hobbs  <jeffh@ActiveState.com>

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

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

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

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

	* generic/tclTest.c:
	* tests/fileSystem.text: fixed test 7.2 to avoid a possible
	crash, and not change the pwd.
	
	* tests/http.text: added comment to test 4.15, that it may
	fail if you use a proxy server.
	
2003-02-06  Mo DeJong  <mdejong@users.sourceforge.net>

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

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

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

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

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

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

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

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

	* generic/tclIOUtil.c:
	* generic/tclEvent.c:
	* generic/tclInt.h:
	* mac/tclMacFCmd.c:
	* unix/tclUnixFCmd.c:
	* win/tclWin32Dll.c:
	* win/tclWinFCmd.c:
	* win/tclWinInit.c:
	* win/tclWinInt.h:
	* tests/fileSystem.test: fix to finalization/unloading/encoding
	issues to make filesystem much less dependent on encodings for
	its cleanup, and therefore allow it to be finalized later in the
	exit process.  This fixes fileSystem.test-7.1.  Also fixed one
	more bug in setting of modification dates of files which have 
	undergone cross-platform copies.  [Patch 676271]
	
	* tests/basic.test:
	* tests/exec.test:
	* tests/fileName.test:
	* tests/io.test: fixed some test failures when tests are run 
	from a directory containing spaces.
	
	* tests/fileSystem.test:
	* generic/tclTest.c: added regression test for the modification
	date setting of cross-platform file copies.
	
2003-02-01  Kevin Kenny  <kennykb@users.sourceforge.net>

	* generic/tclCompCmds.c: Removed an unused variable that caused
	compiler warnings on SGI. [Bug 664379]
	
2003-02-01  Kevin Kenny  <kennykb@users.sourceforge.net>

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

	* tests/load.test Added regression test for the above bug.
	[Bug 670042]
	
2003-02-01  Kevin Kenny  <kennykb@users.sourceforge.net>

	* generic/tclClock.c: Fixed a bug that incorrectly allowed
	[clock clicks {}] and [clock clicks -] to be accepted as if
	they were [clock clicks -milliseconds].
	
	* tests/clock.test: Added regression tests for the above bug.
	[Bug 675356]
	
2003-02-01  Kevin Kenny  <kennykb@users.sourceforge.net>

	* tests/unixNotfy.test: Added cleanup of working files
	[Bug 675609]
	
2003-02-01  Kevin Kenny  <kennykb@users.sourceforge.net>

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

	* generic/tclClock.c: Expanded mutex protection around the setting
	of env(TZ) and the thread-unsafe call to tzset(). [Bug 656660]
	
2003-01-31  Don Porter  <dgp@users.sourceforge.net>

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

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

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

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

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

	* generic/tclIOUtil.c: fix to setting modification date
	in TclCrossFilesystemCopy.  Also added 'panic' in 
	Tcl_FSGetFileSystemForPath under illegal calling circumstances
	which lead to hard-to-track-down bugs.
	
	* generic/tclTest.c: added test suite code to allow
	exercising a vfs-crash-on-exit bug in Tcl's finalization caused
	by the encodings being cleaned up before unloading occurs.
	* tests/fileSystem.test: added new 'knownBug' test 7.1
	to demonstrate the crash on exit.

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

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

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

	* win/README: Update msys+mingw URL to release 6.
	This version bundles gcc 3.

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

	* win/configure: Regen.
	* win/configure.in: Add test that checks to
	see if the compiler can cast to a union type.
	* win/tclWinTime.c: Squelch compiler warning
	about union initializer by casting to union
	type when compiling with gcc.

2003-01-25  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIO.c (Tcl_CutChannel, Tcl_SpliceChannel):
	Invoke TclpCutFileChannel and TclpSpliceFileChannel.
	* generic/tclInt.h: Declare TclpCutFileChannel
	and TclpSpliceFileChannel.
	* unix/tclUnixChan.c (FileCloseProc, TclpOpenFileChannel,
	Tcl_MakeFileChannel, TclpCutFileChannel,
	TclpSpliceFileChannel): Implement thread load data
	cut and splice for file channels. This avoids
	an invalid memory ref when compiled with -DDEPRECATED.
	* win/tclWinChan.c (FileCloseProc, TclpCutFileChannel,
	TclpSpliceFileChannel): Implement thread load data
	cut and splice for file channels. This avoids
	an invalid memory ref that was showing up in the
	thread extension.

2003-01-25  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWin32Dll.c (TclpCheckStackSpace, squelch_warnings):
	* win/tclWinChan.c (Tcl_MakeFileChannel, squelch_warnings):
	* win/tclWinFCmd.c (DoRenameFile, DoCopyFile, squelch_warnings):
	Re-implement inline ASM SEH handlers for gcc.
	The esp and ebp registers are now saved on the
	stack instead of in global variables so that
	the code is thread safe. Add additional checks
	when TCL_MEM_DEBUG is defined to be sure the
	values were recovered from the stack properly.
	Remove squelch_warnings functions and add
	a dummy call in the handler methods to squelch
	compiler warnings.

2003-01-25  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure:
	* win/configure.in: Define HAVE_ALLOCA_GCC_INLINE
	when we detect that no alloca function is found
	in malloc.h and we are compiling with GCC.
	Remove HAVE_NO_ALLOC_DECL define.
	* win/tclWin32Dll.c (TclpCheckStackSpace):
	Don't define alloca as a cdecl function.
	Doing this caused a tricky runtime bug because
	the _alloca function expects the size argument
	to be passed in a register and not on the stack.
	To fix this problem, we use inline ASM when
	compiling with gcc to invoke _alloca with the
	size argument loaded into a register.

2003-01-24  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinDde.c (Dde_Init): clarified use of tsdPtr.
	(DdeServerProc): better refcount handling of returnPackagePtr.

	* generic/tclEvent.c (Tcl_Finalize): revert finalize change on
	2002-12-04 to correct the issue with extensions that have TSD
	needing to finalize that before they are unloaded.  This issue
	needs further clarification.

	* tests/unixFCmd.test: only do groups check on unix

2003-01-24  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclStringObj.c: proper fixes for Tcl_SetObjLength and 
	Tcl_AttemptSetObjectLength dealing with string objects with
	both pure-unicode and normal internal representations. 
	Previous fix didn't handle all cases correctly.
	* generic/tclIO.c: Add 'Tcl_GetString()' to ensure the object has
	a valid 'objPtr->bytes' field before manipulating it directly.
	
        This fixes [Bug 635200] and [Bug 671138], but may reduce performance
	of Unicode string handling in some cases. A further patch will
	be applied to address this, once the code is known to be correct.

2003-01-24  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/configure.in: Add test to see if alloca
	is undefined in malloc.h.
	* win/tclWin32Dll.c (TclpCheckStackSpace): Rework
	the SEH exception handler logic to avoid using
	the stack since alloca will modify the stack.
	This was causing a nasty bug that would set the
	exception handler to 0 because it tried to pop
	the previous exception handler off the top of
	the stack.

2003-01-23  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/lset.n: Fixed fault in return values from lset in
	documentation examples [SF Bug #658463] and tidied up a bit at the
	same time.

2003-01-21  Joe English  <jenglish@users.sourceforge.net>
	* doc/namespace.n (namespace inscope): Clarified documentation
	[SF Patch #670110]

2003-01-21  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Set SHLIB_SUFFIX
	so that TCL_SHLIB_SUFFIX will be set to a useful
	value in the generated tclConfig.sh.
	Set SHLIB_LD_LIBS to "" or '${LIBS}' based on
	the --enable-shared flag. This matches the
	UNIX implementation.

2003-01-18  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCkalloc.c: change %ud to %u as appropriate.

2003-01-17  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWinDde.c (DdeServerProc): Deallocate
	the Tcl_Obj returned by ExecuteRemoteObject
	if it was not saved in a connection object.

2003-01-17  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tcl.h: Revert earlier change that
	defined TCL_WIDE_INT_TYPE as long long and
	TCL_LL_MODIFIER as L when compiling with
	mingw. This change ended up causing some
	test case failures when compiling with mingw.
	* generic/tclObj.c (UpdateStringOfWideInt):
	Describe the warning generated by mingw and
	why it needs to be ignored so that someone
	is not tempted to "fix" this problem again
	in the future.

2003-01-16  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclStringObj.c: Tcl_SetObjLength fix for when
	the object has a unicode string rep. Fixes [Bug 635200]
	* tests/stringObj.test: removed 'knownBug' constraint from
	test 14.1 now that this bug is fixed.
	
        * generic/tclInt.h:
	* generic/tclBasic.c:
	* generic/tclCmdMZ.z:
	* tests/trace.test: execution and command tracing bug fixes and
	cleanup.  In particular fixed [Bug 655645], [Bug 615043], 
	[Bug 571385]
	  - fixed some subtle cleanup problems with tracing. This 
	    required replacing Tcl_Preserve/Tcl_Release with a more 
	    robust refCount approach. Solves at least one known crash
	    caused by memory corruption.
	  - fixed some confusion in the code between new style traces
	  (Tcl 8.4) and the very limited 'Tcl_CreateTrace' which existed
	  before.
	  - made behaviour consistent with documentation (several
	    tests even contradicted the documentation before).
	  - fixed some minor error message details
	  - added a number of new tests

2003-01-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinSerial.c (SerialOutputProc): add casts for
	bytesWritten to allow strict compilation (no warnings).

	* tests/winDde.test:
	* win/tclWinDde.c (Tcl_DdeObjCmd): Prevent crash when empty
	service name is passed to 'dde eval' and goto errorNoResult in
	request and poke error cases to free up any allocated data.

2003-01-16  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWin32Dll.c (squelch_warnings): Squelch
	compiler warnings from SEH ASM code.
	* win/tclWinChan.c (squelch_warnings): Squelch
	compiler warnings from SEH ASM code.
	* win/tclWinDde.c: Add casts to avoid compiler
	warnings. Pass pointer to DWORD instead of int
	to avoid compiler warnings.
	* win/tclWinFCmd.c (squelch_warnings): Add casts
	and fixup decls to avoid compiler warnings.
	Squelch compiler warnings from SEH ASM code.
	* win/tclWinFile.c: Add casts and fixup decls
	to avoid compiler warnings. Remove unused variable.
	* win/tclWinNotify.c: Declare as DWORD instead
	of int to avoid compiler warning.
	* win/tclWinReg.c: Add casts to avoid compiler
	warning. Fix assignment in if expression bug.
	* win/tclWinSerial.c: Add casts to avoid compiler
	warnings. Remove unused variable.
	* win/tclWinSock.c: Add casts and fixup decls
	to avoid compiler warnings.

2003-01-14  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclClock.c (FormatClock): corrected typo that
	incorrectly conditionally defined savedTZEnv and savedTimeZone.

2003-01-13  Mo DeJong  <mdejong@users.sourceforge.net>

	Fix mingw build problems and compiler warnings.

	* generic/tcl.h: Add if defined(__MINGW32__)
	check to code that sets the TCL_WIDE_INT_TYPE
	and TCL_LL_MODIFIER.
	* generic/tclClock.c (FormatClock): Don't
	define savedTimeZone and savedTZEnv if
	we are not going to use them.
	* generic/tclEnv.c: Add cast to avoid warning.
	* win/tclWinChan.c: Use DWORD instead of int
	to avoid compiler warning.
	* win/tclWinThrd.c: Only define allocLock,
	allocLockPtr, and dataKey when TCL_THREADS
	is defined. This avoid a compiler warning
	about unused variables.

2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/README: Update msys + mingw URL, the
	new release includes the released 1.0.8
	version of msys which includes a number
	of bug fixes.

2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Pull in
	addition of shell32.lib to LIBS_GUI that
	was added to the Tk tcl.m4 but never made
	it back into the Tcl version.

2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tcl.h: Skip Tcl's define of CHAR,
	SHORT, and LONG when HAVE_WINNT_IGNORE_VOID
	is defined. This avoids a bunch of compiler
	warnings when building with Cygwin or Mingw.
	* win/configure: Regen.
	* win/configure.in: Define HAVE_WINNT_IGNORE_VOID
	when we detect a winnt.h that still defines
	CHAR, SHORT, and LONG when VOID has already
	been defined.
	* win/tcl.m4 (SC_LOAD_TCLCONFIG): Subst the
	TCL_DEFS loaded from tclConfig.sh so that
	Tcl defines can make it into the Tk Makefile.

2003-01-12  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/configure.in: Check for typedefs like LPFN_ACCEPT
	in winsock2.h and define HAVE_NO_LPFN_DECLS if not found.
	* win/tclWinSock.c: Define LPFN_* typedefs if
	HAVE_NO_LPFN_DECLS is defined. This fixes the build
	under Mingw and Cygwin, it was broken by the changes
	made on 2002-11-26.

2003-01-10  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: 
	* win/tclWinInt.h:
	* win/tclWinInit.c: fix to new WinTcl crash on exit with vfs,
	introduced on 2002-12-06.  Encodings must be cleaned up after
	the filesystem.
	
	* win/makefile.vc: fix to minor VC++ 5.2 syntax problem
	
2003-01-09  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompilerReturnCmd):  Corrected off-by-one
	problem with recent commit.  [Bug 633204]

2003-01-09  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c: remove unused variable 'macSpecialCase'
	[Bug 664749]
	
	* generic/tclIOUtil.c:
	* generic/tclInt.h:
	* unix/tclUnixFile.c:
	* mac/tclMacFile.c:
	* win/tclWinFile.c:
	* win/tclWinInt.h:
	* win/tclWin32Dll.c: 
	* tests/cmdAH.test: fix to non-ascii chars in paths when
	setting mtime and atime through 'file (a|m)time $path $time'
	[Bug 634151]

2003-01-08  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c (TclExprFloatError):  Use the IS_NAN macro
	for greater clarity of code.

2003-01-07  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileReturnCmd): 
	* tests/compile.test:	Corrects failure of bytecompiled 
	[catch {return}] to have result TCL_RETURN (not TCL_OK) [Bug 633204].
	This patch is a workaround for 8.4.X.  A new opcode INST_RETURN is a
	better long term solution for 8.5 and later.

2003-01-04  David Gravereaux  <davygrvy@pobox.com>

	* win/makefile.vc:
	* win/rules.vc:  Fixed INSTALLDIR macro problem that blanked itself
	by accident causing the install target to put the tree at the root
	of the drive built on.  Whoops..

	Renamed the 'linkexten' option to be 'staticpkg'.  Added 'thrdalloc'
	to allow the switching _on_ of the thread allocator.  Under testing,
	I found it not to be benificial under windows for the purpose of the
	application I was using it for.  It was more important for this app
	that resources for tcl threads be returned to the system rather than
	saved/moved to the global recycler.  Be extra clean or extra fast
	for the default threaded build?  Let's move to clean and allow it to
	be switched on for users who find it benificial for their use of
	threads.

2002-12-18  David Gravereaux  <davygrvy@pobox.com>

	* win/makefile.vc: some uses of xcopy swapped to the @$(CPY) macro.
	Reported by Joe Mistachkin <joe@mistachkin.com>.

2002-12-17  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclNotify.c (TclFinalizeNotifier, Tcl_SetServiceMode): 
	(Tcl_ThreadAlert): Check that the stub functions are non-NULL
	before calling them.  They could be set to NULL by Tcl_SetNotifier.

2002-12-16  David Gravereaux  <davygrvy@pobox.com>

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

2002-12-13  Don Porter  <dgp@users.sourceforge.net>

	* unix/configure.in:	Updated configure of CVS snapshots to reflect
	* win/configure.in:	the 8.4.1.1 patchlevel.

	* unix/configure:	autoconf
	* win/configure		autoconf

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

	* generic/tclProc.c (ProcessProcResultCode): Fix failure to
	  propagate negative return codes up the call stack. [Bug 647307]
	* tests/proc.test (proc-6.1): Test for Bug 647307

	* generic/tclParseExpr.c (TclParseInteger):  Return 1 for the
	string "0x" (recognize leading "0" as an integer).  [Bug 648441].
	* tests/parseExpr.test (parseExpr-19.1): Test for Bug 648441.

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

	* win/tclWinThrd.c (TclpMasterUnlock):
	* generic/tclThread.c (TclFinalizeThreadData): TclpMasterUnlock
	must exist and be called unconditional of TCL_THREADS. [Bug #651139]

2002-12-08  David Gravereaux  <davygrvy@pobox.com>

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

2002-12-06  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclStubInit.c: regen
	* generic/tclIntPlatDecls.h: regen
	* generic/tclInt.decls: added TclWinResetInterface

	* win/tclWin32Dll.c (TclWinResetInterfaces):
	* win/tclWinInit.c (TclpSetInitialEncodings, WinEncodingsCleanup):
	add exit handler that resets the encoding information to a state
	where we can reuse Tcl.  Following these changes, it is possible
	to reuse Tcl (following Tcl_FindExecutable or Tcl_CreateInterp)
	following a Tcl_Finalize.

	* generic/tclIOUtil.c (TclFinalizeFilesystem): reset statics to
	their original values on finalize to allow reuse of the library.

2002-12-04  David Gravereaux  <davygrvy@pobox.com>

	* win/tclWinPipe.c: reverted back to -r1.27 due to numerous test
	failures that need to be resolved first.  The idea was good,
	but the details aren't.
	
2002-12-04  David Gravereaux  <davygrvy@pobox.com>

	* win/tclWinPipe.c (Tcl_WaitPid):  When a process exits with an
	exception, pass this notice on to the caller with a SIG* code
	rather than truncating the exit code and missing the meaning.
	This allows TclCleanupChildren() to report "CHILDKILLED".

	This has a different behavior than unix in that closing the
	read pipe to a process sends the SIGPIPE signal which is
	returned as a SIGPIPE exit status.  On windows, we send the
	process a CTRL_BREAK_EVENT and get back a CONTROL_C_EXIT which
	is documented to mean a SIGINT which seems wrong as a system,
	but is the correct exit status.

2002-12-04  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: fix to redirected 'load' in virtual
	filesystem for some Unix systems.

	* generic/tclEvent.c: the filesystem must be cleaned up before
	the encoding subsystem because it needs access to encodings.
	Fixes crash on exit observed in embedded applications.

	* generic/tclTestObj.c: patch omitted from previous change
	of 2002-11-13
	
2002-12-03  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclStubLib.c (Tcl_InitStubs): prevent the cached check of
	tclStubsPtr to allow for repeated load/unload of the Tcl dll by
	hosting apps. [Bug 615304]

2002-12-03  David Gravereaux  <davygrvy@pobox.com>

	* win/tclAppInit.c (sigHandler):  Protect from trying to close a
	NULL handle.

	* win/tclWinPipe.c (PipeClose2Proc, TclpCreateProcess):  Send a
	real Win32 signal (CTRL_C_EVENT) when the read channel is brought
	down to alert the child to close on its side.  Start the process
	with CREATE_NEW_PROCESS_GROUP to allow the ability to send these
	signals.  The following test case now brings down the child
	without the use of an external [kill] command.

	% set p [open "|[info name]" w+]
	file8d5380
	% pid $p
	2876
	% close $p     <- now doesn't block in Tcl_WaitPid()
	%

	* win/tclWinPipe.c (PipeClose2Proc):  Changed CTRL_C_EVENT
	to CTRL_BREAK_EVENT as it can't be ignored by the child and
	proved to work on [open "|netstat 1" w+] where CTRL_C_EVENT
	didn't.

2002-11-27  David Gravereaux  <davygrvy@pobox.com>

	* win/tclWinPort.h:  Don't turn off winsock prototypes!
	TclX didn't like it.  Even though the core doesn't use the
	prototypes, do offer them.

	* win/tclWinSock.c:  Removed shutdown() from the function
	table as it wasn't referenced anywhere and cleaned-up some
	casting that that wasn't needed.

	* win/tclWinSock.c:  WSAStartup() loaded version comparison
	error which resulted in 2.0 looking less than 1.1.

	* win/tclWinChan.c (Tcl_MakeFileChannel):  return of
	DuplicateHandle() incorrectly used [Bug 618852].

2002-11-26  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclEncoding.c (TclFinalizeEncodingSubsystem): properly
	cleanup all encodings by using Tcl_FirstHashEntry in the while loop.

	* unix/Makefile.in (valgrind): add simple valgrind target

	* tests/exec.test: unset path var to allow singleproc testing

	* generic/tclInterp.c (AliasCreate): preserve/release interps to
	prevent possible FMR error in bad alias cases.

2002-11-26  David Gravereaux  <davygrvy@pobox.com>

	* win/tclWinPort.h:
	* win/tclWinSock.c:  This patch does two things:

	1) Cleans-up the winsock typedefs by using the typedefs
	provided by winsock2.h.  This has no effect on how winsock
	is initialized; just makes the source code easier to read.
	[Patch 561305 561301]

	2) Revamps how the socket message handler thread is brought
	up and down to allow for cleaner exits without the use of
	TerminateThread().  TerminateThread is evil.  No attempt has
	been made to resolve [Bug 593810] which may need a new
	channel driver version for adding a registering function
	within the transfered thread to init the handler thread.
	IOW, initialization of the TSD structure is getting bypassed
	through the thread extension's [thread::transfer] command.

2002-11-26  David Gravereaux  <davygrvy@pobox.com>

	* win/tclWinConsole.c:
	* win/tclWinPipe.c:
	* win/tclWinSerial.c:
	* win/tclWinSock.c:
	* win/tclWinThrd.c:
	* win/tclWinTime.c:  General cleanup of all worker threads used
	by the channel drivers.  Eliminates the normal case where the
	worker thread is terminated ('cept the winsock one).  Instead,
	use kernel events to signal a clean exit.  Only when the worker
	thread is blocked on an I/O call is the thread terminated.
	Essentially, this makes all other channel worker threads behave
	like the PipeReaderThread() function for it's cleaner exit
	behavior.  This appears to fix [Bug 597924] but needs 3rd party
	confirmation to close the issue.

2002-11-26  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/README: Update msys build env URL. This
	release #4 build both tcl and tk without problems.

2002-11-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* library/init.tcl:         code cleanup to reduce use of
	* library/opt/optparse.tcl: string compare

	* tests/interp.test: interp-14.4
	* generic/tclInterp.c (TclPreventAliasLoop): prevent seg fault
	when creating an alias command over the interp name. [Bug #641195]

2002-11-18  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclUtil.c (SetEndOffsetFromAny): handle integer offset
	after the "end-" prefix.

	* generic/get.test:
	* generic/string.test:
	* generic/tclObj.c (SetIntFromAny, SetWideIntFromAny): 
	* generic/tclGet.c (TclGetLong, Tcl_GetInt): simplify sign
	handling before calling strtoul(l). [Bug #634856]

2002-11-18  David Gravereaux  <davygrvy@pobox.com>

	* win/tclWinThrd.c (Tcl_CreateThread/TclpThreadExit): Fixed
	improper compiler macros that missed the VC++ compiler.  This
	resulted in VC++ builds using CreateThread()/ExitThread() in place
	of the proper _beginthreadex()/_endthreadex().  This was a large
	error and am surprised I missed seeing it earlier.

2002-11-13  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/regexpComp.test: added tests 22.*
	* generic/tclCompCmds.c (TclCompileRegexpCmd): add left and right
	anchoring (^ and $) recognition and check starting or ending .* to
	extend the number of REs that can be compiled to string match or
	string equal.

2002-11-13  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclCmdMZ.c:
	* tests/trace.test: applied patch from Hemang Levana to fix
	[Bug #615043] in execution traces with 'return -code error'.
	
	* generic/tclTestObj.c:
	* tests/stringObj.test: added 'knownBug' test for [Bug 635200]
	* generic/tclStringObj.c: corrected typos in comments

	* generic/tclFileName.c:
	* tests/fileName.test: applied patch for bug reported against
	tclvfs concerning handling of Windows serial ports like 'com1',
	'lpt3' by the virtual filesystem code.

	* doc/RegExp.3: clarification of the 'extendMatch' return
	values.

2002-11-11  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclUtil.c (Tcl_Backslash): use TclUtfToUniChar.
	(Tcl_StringCaseMatch): use TclUtfToUniChar and add further
	optimizations for the one-byte/char case.

	* generic/tclUtf.c: make use of TclUtfToUniChar macro throughout
	the functions, and add extra optimization to Tcl_NumUtfChars for
	one-byte/char case.

	* generic/tclVar.c (DisposeTraceResult, CallVarTraces): add proper
	static declarations.

	* generic/tclStringObj.c (Tcl_GetCharLength): optimize for the
	ascii char case.
	(Tcl_GetUniChar): remove unnecessary use of Tcl_UtfToUniChar.
	(FillUnicodeRep): Use TclUtfToUniChar.

	* generic/tclHash.c (HashStringKey): move string++ lower to save
	an instruction.

	* generic/tclExecute.c (TclExecuteByteCode): improve INST_STR_CMP
	to use memcmp in the one-byte/char case, also use direct index for
	INST_STR_INDEX in that case.

	* generic/tclEncoding.c (UtfToUtfProc, UtfToUnicodeProc): 
	(TableFromUtfProc, EscapeFromUtfProc): Use TclUtfToUniChar.
	(UnicodeToUtfProc, TableToUtfProc): add 1-byte char optimizations
	for Tcl_UniCharToUtf call.  These improve encoded channel
	conversion speeds by up to 20%.

	* tests/split.test: added 1-char string split tests
	* generic/tclCmdMZ.c (Tcl_SplitObjCmd): Use TclUtfToUniChar.
	Also added a special case for single-ascii-char splits.
	(Tcl_StringObjCmd): Use TclUtfToUniChar.
	For STR_RANGE, support getting ranges of ByteArrays (reverts
	change from 2000-05-26).
	(TraceExecutionProc) add proper static declaration.

	* generic/tclInt.h: add macro version of Tcl_UtfToUniChar
	(TclUtfToUniChar) that does the one-byte utf-char check without
	calling Tcl_UtfToUniChar, for use by the core.  This brings
	notable speedups for primarily ascii string handling.

	* generic/tcl.h (TCL_PATCH_LEVEL): bump to 8.4.1.1 for patchlevel
	only.  This interim number will only be reflected by
	[info patchlevel].

2002-11-11  Kevin Kenny  <kennykb@acm.org>
	* doc/Tcl.n: Corrected indentation of the new language.  Oops.
	
2002-11-10  Kevin Kenny <kennykb@acm.org>

	* doc/Tcl.n: Added language to the Endekalogue to make it clear
	that substitutions always take place from left to right. [Bug
	#635644]

2002-11-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* changes: Note TclInExit TclInThreadExit changes.
	* generic/tclEvent.c (TclInExit, TclInThreadExit):
	Split out functionality of TclInExit to make it
	clear which one should be called in each situation.
	* generic/tclInt.decls: Declare TclInThreadExit.
	* generic/tclIntDecls.h: Regen.
	* generic/tclStubInit.c: Regen.
	* mac/tclMacChan.c (StdIOClose):
	* unix/tclUnixChan.c (FileCloseProc):
	* win/tclWinChan.c (FileCloseProc):
	* win/tclWinConsole.c (ConsoleCloseProc):
	* win/tclWinPipe.c (TclpCloseFile):
	* win/tclWinSerial.c (SerialCloseProc): Invoke the
	new TclInThreadExit method instead of TclInExit.

2002-11-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Generate a fatal
	configure error if no ar program can be found on the
	path. [Bug #582039]
	* win/configure: Regen.
	* win/configure.in: Check that AR, RANLIB, and RC
	are found on the path when building with gcc.

2002-11-03  David Gravereaux <davygrvy@pobox.com>

	* win/tclAppInit.c:  Calls Registry_Init() and Dde_Init() when
	STATIC_BUILD and TCL_USE_STATIC_PACKAGES macros are set.

	* win/makefile.vc:
	* win/rules.vc:  linkexten option now sets the TCL_USE_STATIC_PACKAGES
	macro which also adds the registry and dde object files to the link
	of the shell. [Patch 479697]  Also factored some additional macros
	that will be helpful for extension authors.  Version grepping of tcl.h
	will need to be added to complete this.

	* win/buildall.vc.bat: Added more descriptive commentary.

2002-11-01  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinReg.c:  Changed the Tcl_PkgProvide() line to declare
	the registry extension at version 1.1 from 1.0.

2002-10-31  Andreas Kupries  <andreask@activestate.com>

	* library/word.tcl: Changed $tcl_platform to $::tcl_platform to
	  avoid possible scope trouble.

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

	* win/tclWinInt.h:
	* win/tclWin32Dll.c: added comments about certain NULL function
	pointers which will be filled in when Tcl_FindExecutable is
	called, so that users don't report invalid bugs on this topic.
	(No code changes at all).
	
2002-10-29  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclLoadDyld.c (TclpFindSymbol): pass all dyld error
	messages upstream [Bug #627546].

	* library/tclIndex:	[Patch 624509] (steffen)

2002-10-26  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc: xcopy on NT 4.0 doesn't support the /Y switch
	(overwrite).  Added logic to handle this.  [Bug 618019]

2002-10-23  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclInt.h: Removed definitions of obsolete HistoryEvent
	and HistoryRev structures (the history mechanism has been written
	in Tcl for some time now.)

2002-10-22  Jeff Hobbs  <jeffh@ActiveState.com>

	*** 8.4.1 TAGGED FOR RELEASE ***

	the dirs in DYLD_FRAMEWORK_PATH (if set). [Patch #624509]
	use standard MAXPATHLEN instead of literal 1024

2002-10-22  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/StringObj.3, doc/Object.3: Documented that Tcl_Obj's
	standard string form is a modified UTF-8; apparently, this was not
	mentioned anywhere in the main docs, and lead to [Bug 624919].

2002-10-21  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.pbproj/project.pbxproj: bumped version to 8.4.1

	Fixes [Bug 611108]

2002-10-09  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/README: doc'ed --enable-symbols options.
	* unix/Makefile.in: removed @MEM_DEBUG_FLAGS@ subst.

2002-10-09  Kevin B. Kenny  <kennykb@acm.org>

	* win/tclWinTime.c: Added code to set an exit handler that
	terminates the thread that calibrates the performance counter, so
	that the thread won't outlive unloading the Tcl DLL. [Tcl bug
	620735].

2002-10-09  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	generic as it is used on mac & aqua as well.
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c: regen.
	* generic/tclCompile.h: added prototype for TclCompileVariableCmd.

	* mac/tclMacPort.h: removed incorrect <fcntl.h> definitions
	and obsolete <stat.h> definitions.
	* mac/tclMacChan.c: removed obsolete GetOpenMode() and replaced 
	associated constants with the <fcntl.h> analogues (they existing
	defs were inconsistent with <fcntl.h> which was causing havoc when
	Tcl_GetOpenMode was used instead of private GetOpenMode).

2002-10-01  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclProc.c (TclCreateProc): mask out VAR_UNDEFINED for
	precompiled locals to support 8.3 precompiled code.
	(Tcl_ProcObjCmd): correct 2002-09-26 fix to look for tclProcBodyType.

2002-10-01  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/socket.n: Mentioned that ports may be specified as serivce
	names as well as integers. [Bug 616843]

2002-09-30  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCompCmds.c (TclCompileRegexpCmd): correct the
	checking for bad re's that didn't terminate the re string.
	Resultant compiles were correct, but much slower than necessary.

2002-09-29  David Gravereaux <davygrvy@pobox.com>

	* win/tclAppInit.c: Added proper exiting conditions using Win32
	console signals.  This handles the existing lack of a Ctrl+C exit
	to call exit handlers when built for thread support.  Also, properly
	handles exits from other conditions such as CTRL_CLOSE_EVENT,
	CTRL_LOGOFF_EVENT, and CTRL_SHUTDOWN_EVENT signals.  In all cases,
	exit handlers will be called.  [Bug 219355]

	* win/makefile.vc: Added missing tclThreadAlloc.c to the build
	rules and defines USE_THREAD_ALLOC when TCL_THREADS is defined
	to get the new behavior by default.

2002-09-27  Don Porter  <dgp@users.sourceforge.net>

	* README:		Bumped to version 8.4.1 to avoid confusion
	* generic/tcl.h:	of CVS snapshots with the actual 8.4.0

2002-09-26  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/configure: regen.
	* unix/tcl.m4: improve AIX-4/5 64bit compilation support.

	* generic/tclProc.c (Tcl_ProcObjCmd): correct overeager
	optimization of noop proc to handle the precompiled case. (sofer)

	* unix/ldAix (nmopts): add -X32_64 to make it work for 32 or 64bit
	mode compilation.

	* library/encoding/koi8-u.enc: removed extraneous spaces that
	confused encoding reader. [Bug #615115]

	* unix/Makefile.in: generate source dists with -src designator and
	do not generate .Z anymore (just .gz and .zip).

2002-09-18  Mumit Khan <khan@nanotech.wisc.edu>

	Added basic Cygwin support.

	* win/tcl.m4 (SC_PATH_TCLCONFIG): Support one-tree build.
	(SC_PATH_TKCONFIG): Likewise.
	(SC_PROG_TCLSH): Likewise.
	(SC_CONFIG_CFLAGS): Assume real Cygwin port and remove -mno-cygwin 
	flags.  Add -mwin32 to extra_cflags and extra_ldflags.
	Remove ``-e _WinMain@16'' from LDFLAGS_WINDOW.
	* win/configure.in: Allow Cygwin build.
	(SEH test): Define to be 1 instead of empty value.
	(EXCEPTION_DISPOSITION): Add test.
	* win/configure: Regenerate.

	* generic/tcl.h: Don't explicitly define __WIN32__ for Cygwin, let
	the user decide whether to use Windows or POSIX personality.
	(TCL_WIDE_INT_TYPE, TCL_LL_MODIFIER, struct Tcl_StatBuf): Define
	for Cygwin.
	* generic/tclEnv.c (Tcl_CygwinPutenv): putenv replacement for
	Cygwin.
	* generic/tclFileName.c (Tcl_TranslateFileName): Convert POSIX 
	to native format.
	(TclDoGlob): Likewise.
	* generic/tclPlatDecls.h (TCHAR): Define for Cygwin.
	* win/tclWinPort.h (putenv, TclpSysAlloc, TclpSysFree, 
	TclpSysRealloc): Define for Cygwin.

2002-09-26  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Makefile: preserve environment value of INSTALL_ROOT.
	When embedding only use deployment build. Force relink before
	embedded build to ensure new linker flags are picked up.

	* macosx/Tcl.pbproj/project.pbxproj: add symbolic links to
	debug lib, stub libs and tclConfig.sh in framework toplevel.
	Configure target dependency fix. Fix to 'clean' action. Added
	private tcl headers to framework. Install tclsh symbolic link.
	Html doc build works when no installed tclsh available. Made
	html doc structure in framework more like in Apple frameworks.

2002-09-24  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* unix/tcl.m4 (SC_TCL_64BIT_FLAGS): Yet more robust 64-bit value
	detection to close [Bug 613117] on more systems.

	* generic/tclCompile.c (TclPrintSource): More CONSTifying.
	* generic/tclExecute.c (EvalStatsCmd): Object-ify to reduce
	warnings.  Thanks to 'CoderX2' on the chat for bringing this to my
	attention...

	* unix/tcl.m4: Forgot to define TCL_WIDE_INT_IS_LONG at the
	appropriate moment.  I believe this is the cause of [Bug 613117]

	* doc/lset.n: Changed 'list' to 'varName' for consistency with
	lappend documentation.  Thanks to Glenn Jackman [Bug 611719]

2002-09-22  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:  Corrected [puts -nonewline] within
	test bodies.  Thanks to Harald Kirsch.  [Bug 612786, Patch 612788]
	Also corrected reporting of body return code.  Thanks to David
	Taback [Bug 611922]
	* library/tcltest/pkgIndex.tcl: Bump to version 2.2.1.
	* tests/tcltest.test: added tests for these bugs.

2002-09-15  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Add PEEK_XCLOSEIM
	define under Linux. This is used by Tk to double
	check that an X input context is cleaned up
	before it is closed.

2002-09-12  David Gravereaux <davygrvy@pobox.com>

	* win/coffbase.txt: Added BLT to the virtual base address
	listings table should BLT's build tools decide to use it.

2002-09-12  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tcl.h:
	* mac/tclMacApplication.r:
	* mac/tclMacLibrary.r:
	* mac/tclMacResource.r: unified use of the two equivalent 
	resource compiler header inclusion defines RC_INVOKED and
	RESOURCE_INCLUDED, now use RC_INVOKED throughout. 

2002-09-10  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/README: Add note about building extensions
	with the same compiler Tcl was built with.
	[Tk Bug 592096]

2002-09-10  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.pbproj/project.pbxproj: disabled building html
	documentation during embedded build.

2002-09-10  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in: added DYLIB_INSTALL_DIR variable for macosx
	and set it to default value ${LIB_RUNTIME_DIR}
	* unix/tcl.m4 (Darwin): use DYLIB_INSTALL_DIR instead of
	LIB_RUNTIME_DIR in the -install_name argument to ld.
	* unix/configure: regen.

	* macosx/Tcl.pbproj/project.pbxproj:
	* macosx/Makefile: added support for building Tcl as an embedded
	framework, i.e. using an dyld install_name containing
	@executable_path/../Frameworks via the new DYLIB_INSTALL_DIR
	unix/Makefile variable.

2002-09-06  Reinhard Max  <max@suse.de>

	* tests/tcltest.test: Added nonRoot flag to tests 8.3, 8.4, and 8.12.

2002-09-05  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n:  Clarified phrasing.

	* generic/tclBasic.c (TclRenameCommand,CallCommandTraces):
	* tests/trace.test (trace-27.1): Corrected memory leak when a rename
	trace deleted the command being traced.  Test added.  Thanks to
	Hemang Lavana for the fix.  [Bug 604609]

	* generic/tclVar.c (TclDeleteVars):  Corrected logic for setting the
	TCL_INTERP_DESTROYED flag when calling variable traces. [Tk Bug 605121]

2002-09-04  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclVar.c (DeleteArray): leak plug [Bug 604239]. Thanks
	to dkf and dgp for the long and difficult discussion in the chat.

2002-09-03  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclVar.c (Tcl_UpVar2): code cleanup to not use goto

	* unix/configure: remove -pthread from LIBS on FreeBSD in thread
	* unix/tcl.m4:    enabled build. [Bug #602849]

2002-09-03  Miguel Sofer  <msofer@users.sourceforge.net>

	return from TclPreventAliasLoop.
	
2002-09-03  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.pbproj/project.pbxproj: Bumped version number to
	8.4.0 and updated copyright info.

2002-09-03  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclVar.c (Tcl_UpVar2): a Tcl_Obj was being leaked on
	error return from TclGetFrame.

2002-09-03  Don Porter  <dgp@users.sourceforge.net>

	* changes:  Updated changes for 8.4.0 release.

2002-09-02  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixFile.c (TclpObjLink): removed unnecessary/unfreed
	extra native char*.

	* unix/tclUnixChan.c (Tcl_MakeTcpClientChannel): make sure to init
	flags field of TcpState ptr to 0.

	* unix/configure:
	* unix/tcl.m4: added 64-bit gcc compilation support on HP-11.
	[Patch #601051] (martin)

	* unix/tcl.spec:
	* win/README.binary:
	* win/configure:
	* win/configure.in:

	* generic/tclInterp.c (SlaveCreate): make sure that the memory and
	checkmem commands are initialized in non-safe slave interpreters
	when TCL_MEM_DEBUG is used. [Bug #583445]

	* win/tclWinConsole.c (ConsoleCloseProc): only wait on writable
	pipe if there was something to write.  This may prevent infinite
	wait on exit.

	* tests/exec.test: marked exec-18.1 unixOnly until the Windows
	incompatability (in the test, not the core) can be resolved.

	* tests/http.test (http-3.11): added close $fp that was causing an
	error on Windows because the file was not closed before deleting.

	* unix/tclUnixInit.c (Tcl_MacOSXGetLibraryPath): made this static
	function only appear when HAVE_CFBUNDLE is defined.

2002-08-31  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4: added TK_SHLIB_LD_EXTRAS analogue of existing
	TCL_SHLIB_LD_EXTRAS for linker settings only used when linking Tk.

	* unix/configure: regen

2002-08-31  Daniel Steffen  <das@users.sourceforge.net>

	*** macosx-8-4-branch merged into the mainline [tcl patch #602770] ***

	* generic/tcl.decls: added new macosx specific entry to stubs table.

	* tools/genStubs.tcl: added generation of platform guards for
	macosx. This is a little more complex than it seems, because MacOS
	X IS "unix" plus a little bit, for the purposes of Tcl. BUT
	unfortunately, Tk uses "unix" to mean X11. So added platform keys
	for macosx (the little added to "unix"), "aqua" and "x11" to
	distinguish these for Tk.
	
	* generic/tcl.h: added a #ifnded RESOURCE_INCLUDED so that tcl.h
	can be passed to the resource compiler.
	
	* generic/tcl.h:
	* generic/tclNotify.c: added a few Notifier procs, to be able to
	modify more bits of the Tcl notifier dynamically. Required to get
	Mac OS X Tk to live on top of the Tcl Unix threaded notifier.
	Changes the size of the Tcl_NotifierProcs structure, but doesn't
	move any elements around.

	* unix/tclUnixNotfy.c: moved the call to Tcl_ConditionNotify till
	AFTER we are done mucking with the pointer swap. Fixes cases where
	the thread waiting on the condition wakes & accesses the
	waitingListPtr before it gets reset, causing a hang.

	* library/auto.tcl (tcl_findLibrary): added checking the
	directories in the tcl_pkgPath for library files on macosx to
	enable support of the standard Mac OSX library locations

	* unix/Makefile.in:
	* unix/configure.in:
	* unix/tcl.m4: added MAC_OSX_DIR.  Added PLAT_OBJS to the OBJS:
	there are some MacOS X specific files now for Tcl, and when I get
	he resource & applescript stuff ported over, and restore support
	for FindFiles, etc, there will be a few more.
	Added LD_LIBRARY_PATH_VAR configure variable to avoid having to set
	all possible LD_LIBRARY_PATH analogues on all platforms.
	LD_LIBRARY_PATH_VAR is "LD_LIBRARY_PATH" by default, "LIBPATH" on
	AIX, "SHLIB_PATH" on HPUX and "DYLD_LIBRARY_PATH" on Mac OSX.
	Added configure option to package Tcl as a framework on Mac OSX.

	* macosx/tclMacOSXBundle.c (new): support for finding Tcl extension
	packaged as 'bundles' in the standard Mac OSX library locations.

	* unix/tclUnixInit.c: added support for findig the tcl script
	library inside Tcl packaged as a framework on Mac OSX.

	* macosx/Tcl.pbproj/jingham.pbxuser (new):
	* macosx/Tcl.pbproj/project.pbxproj (new): project for Apple's
	ProjectBuilder IDE.

	* macosx/Makefile (new): simple makefile for building the project
	from the command line via the ProjectBuilder tool 'pbxbuild'.

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

2002-08-29  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* win/tclWinThrd.c (TclpFinalizeThreadData, TclWinFreeAllocCache):
	  Applied patch for bug #599428, provided by Miguel Sofer
	  <msofer@users.sourceforge.net>.

2002-08-28  David Gravereaux <davygrvy@pobox.com>

	* generic/tclEnv.c:
	* unix/configure.in:
	* win/tclWinPort.h:  putenv() on some systems copies the buffer
	rather than taking reference to it.  This causes memory leaks
	and is know to effect mswindows (msvcrt) and NetBSD 1.5.2 .  This
	patch tests for this behavior and turns on -DHAVE_PUTENV_THAT_COPIES=1
	when approriate.  Thanks to David Welton for assistance.
	[Bug 414910]

	* unix/configure: regen'd

2002-08-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/eval.n: Added mention of list command and corrected "SEE ALSO".

	* unix/configure.in: Cache handling of ac_cv_type_socklen_t was
	wrong. [Bug 600931] reported by John Ellson.  Fixed by putting the
	brackets where they belong.

2002-08-26  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompCmds.c: fix for [Bug 599788] (error in element
	name causing segfault), reported by Tom Wilkason. Fixed by copying
	the tokens instead of the source string.

2002-08-26  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclThreadAlloc.c: small optimisation, reducing the
	new allocator's overhead.
	
2002-08-23  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclObj.c (USE_THREAD_ALLOC): fixed leak [Bug 597936]. 
	Thanks to Zoran Vasiljevic.

2002-08-23  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclThreadAlloc.c (USE_THREAD_ALLOC): moving objects
	between caches as a block, instead of one-by-one.

2002-08-22  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c:
	* generic/tclCmdMZ.c: fix for freed memory r/w in delete traces
	[Bug 589863], patch by Hemang Lavana.

2002-08-20  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* win/Makefile.in (CFLAGS): 
	* unix/Makefile.in (MEM_DEBUG_FLAGS): Added usage of @MEM_DEBUG_FLAGS@.
	* win/configure.in:
	* unix/configure.in: Added usage of SC_ENABLE_MEMDEBUG.
	* win/tcl.m4:
	* unix/tcl.m4: Added macro SC_ENABLE_MEMDEBUG. Allows a user of
	  configure to (de)activate memory validation and debugging
	  (TCL_MEM_DEBUG). No need to modify the makefile anymore.

2002-08-20  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCkalloc.c:	CONSTified MemoryCmd and CheckmemCmd.

	* README:		Bumped version number to 8.4b3 to distinguish
	* generic/tcl.h:	HEAD from the 8.4b2 release.
	* tools/tcl.wse.in:
	* unix/configure.in:
	* unix/tcl.spec:
	* win/README.binary:
	* win/configure.in:

	* unix/configure:	autoconf
	* win/configure:

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

2002-08-19  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* unix/tclUnixTest.c (TestfilehandlerCmd): Changed
	  readable/writable to the more common readable|writable.

	  Fixes SF #596034 reported by Larry Virden
	  <lvirden@users.sourceforge.net>.

2002-08-16  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/fCmd.test: Added test to make sure that the cause of the
	problem is detectable with an unpatched Tcl.
	* doc/ObjectType.3: Added note on the root cause of this problem
	to the documentation, since it is possible for user code to
	trigger this sort of behaviour too.
	* generic/tclIOUtil.c (SetFsPathFromAny): Objects should only have
	their old representation deleted when we know that we are about to
	install a new one.  This stops a weird TclX bug under Linux with
	certain kinds of memory debugging enabled which essentally came
	down to a double-free of a string.

2002-08-14  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclInt.h:
	* generic/tclObj.c: (code cleanup) factored the parts in the macros 
	TclNewObj() / TclDecrRefCount() into a common part for all
	memory allocators and two new macros TclAllocObjStorage() /
	TclFreeObjStorage() that are specific to each allocator and fully
	describe the differences. Removed allocator-specific code from
	tclObj.c by using the macros.
	
2002-08-12  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCmdMZ.c: fixing UMR in delete traces, [Bug 589863].
	
2002-08-08  David Gravereaux <davygrvy@pobox.com>

	* tools/man2help.tcl: Fixed $argv handling bug where if -bitmap
	wasn't specified $argc was off by one.

2002-08-08  Miguel Sofer  <msofer@users.sourceforge.net>

	* tests/uplevel.test: added 6.1 to test [uplevel] with shadowed
	commands [Bug 524383]

	* tests/subst.test: added 5.8-10 as further tests for [Bug 495207] 

2002-08-08  Don Porter  <dgp@users.sourceforge.net>

	* tests/README: Noted removal of defs.tcl.

2002-08-08  Jeff Hobbs  <jeffh@ActiveState.com>

	* doc/lsearch.n: corrected lsearch docs to use -inline in examples.

	*** 8.4b2 TAGGED FOR RELEASE ***

	* tests/fCmd.test:
	* tests/unixFCmd.test: updated tests for new link copy behavior.
	* generic/tclFCmd.c (CopyRenameOneFile): changed the behavior to
	follow links to endpoints and copy that file/directory instead of
	just copying the surface link.  This means that trying to copy a
	link that has no endpoint (danling link) is an error.
	[Patch #591647] (darley)
	(CopyRenameOneFile): this is currently disabled by default until
	further issues with such behavior (like relative links) can be
	handled correctly.

	* tests/README: slight wording improvements

2002-08-07  Miguel Sofer  <msofer@users.sourceforge.net>

	* docs/BoolObj.3: added description of valid string reps for a
	boolean object [Bug 584794]
	* generic/tclObj.c: optimised Tcl_GetBooleanFromObj and
	SetBooleanFromAny to avoid parsing the string rep when it can be
	avoided [Bugs 584650, 472576]
	
2002-08-07  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompile.h:
	* generic/tclObj.c: making tclCmdNameType static ([Bug 584567],
	Don Porter).
	
2002-08-07  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclObj.c (Tcl_NewObj): added conditional code for
	USE_THREAD_ALLOC; objects allocated through Tcl_NewObj() were
	otherwise being leaked. [Bug 587488] reported by Sven Sass.
	
2002-08-06  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclInt.decls:
	* unix/tclUnixThrd.c: Added stubs and implementations for
	non-threaded build for the tclUnixThrd.c procs TclpReaddir,
	TclpLocaltime, TclpGmtime and TclpInetNtoa.
	Fixes link errors in stubbed & threaded extensions that include
	tclUnixPort.h and use any of the procs readdir, localtime, 
	gmtime or inet_ntoa (e.g. TclX 8.4) [Bug 589526]
	* generic/tclIntPlatDecls.h:
	* generic/tclStubInit.c: Regen.

2002-08-05  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:	The setup and cleanup scripts are now
	* library/tcltest/pkgIndex.tcl:	skipped when a test is skipped, fixing
	* tests/tcltest.test:		[Bug 589859].  Test for bug added, and
	corrected tcltest package bumped to version 2.2.

	* generic/tcl.decls:	Restored Tcl_Concat to return (char *).  Like
	* generic/tclDecls.h:	Tcl_Merge, it transfers ownership of a dynamic
	* generic/tclUtil.c:	allocated string to the caller.

2002-08-04  Don Porter  <dgp@users.sourceforge.net>

	* doc/CmdCmplt.3:	Applied Patch 585105 to fully CONST-ify
	* doc/Concat.3:		all remaining public interfaces of Tcl.
	* doc/CrtCommand.3:	Notably, the parser no longer writes on 
	* doc/CrtSlave.3:	the string it is parsing, so it is no
	* doc/CrtTrace.3:	longer necessary for Tcl_Eval() to be
	* doc/Eval.3:		given a writable string.  Also, the
	* doc/ExprLong.3:	refactoring of the Tcl_*Var* routines
	* doc/LinkVar.3:	by Miguel Sofer is included, so that the
	* doc/ParseCmd.3:	"part1" argument for them no longer needs
	* doc/SetVar.3:		to be writable either.
	* doc/TraceVar.3:
	* doc/UpVar.3:		Compatibility support has been enhanced so
	* generic/tcl.decls	that a #define of USE_NON_CONST will remove
	* generic/tcl.h		all possible source incompatibilities with
	* generic/tclBasic.c	the 8.3 version of the header file(s).
	* generic/tclCmdMZ.c	The new #define of USE_COMPAT_CONST now does
	* generic/tclCompCmds.c	what USE_NON_CONST used to do -- disable
	* generic/tclCompExpr.c only those new CONST's that introduce
	* generic/tclCompile.c	irreconcilable incompatibilities.

2002-08-01  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: bugfix (reading freed memory). Testsuite
	passed on linux/i386, compile-13.1 hung on linux/alpha.

2002-08-01  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: added a reference count for the complete
	execution stack, instead of Tcl_Preserve/Tcl_Release. 

2002-08-01  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclCkalloc.c (TclFinalizeMemorySubsystem):
	Don't lock the ckalloc mutex before invoking the
	Tcl_DumpActiveMemory function since it also
	locks the same mutex. This code is only executed
	when "memory onexit filename" has been executed
	and Tcl is compiled with -DTCL_MEM_DEBUG.

2002-08-01  Reinhard Max  <max@suse.de>

	* win/tclWinPort.h: The windows headers don't provide socklen_t,
	so we have to do it.

2002-07-31  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclInt.h (USE_THREAD_ALLOC): for unshared objects,
	TclDecrRefCount now frees the internal rep before the string rep -
	just like the non-macro Tcl_DecrRefCount/TclFreeObj [Bug 524802]. 
	For the other allocators the fix was done on 2002-03-06.

2002-07-31  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclInterp.c: signed/unsigned comparison warning fixed
	(Vince Darley).

2002-07-31  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* unix/tcl.m4 (SC_BUGGY_STRTOD): Enabled caching of test results.

	* unix/tcl.m4 (SC_BUGGY_STRTOD): Solaris 2.8 still has a buggy
	strtod() implementation; make sure we detect it.

	* tests/expr.test (expr-22.*): Marked as non-portable because it
	seems that these tests have an annoying tendency to fail in
	unexpected ways.  [Bugs 584825, 584950, 585986]

2002-07-30  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* tests/io.test: 
	* generic/tclIO.c (WriteChars): Added flag to break out of loop if
	  nothing of the input is consumed at all, to prevent infinite
	  looping of called with a non-UTF-8 string. Fixes Bug 584603
	  (partially). Added new test "io-60.1". Might need additional
	  changes to Tcl_Main so that unprintable results are printed as
	  binary data.

2002-07-29  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in: Use CC_SEARCH_FLAGS instead of
	LD_SEARCH_FLAGS when linking with ${CC}.
	* unix/configure: Regen.
	* unix/configure.in: Don't subst CC_SEARCH_FLAGS or
	LD_SEARCH_FLAGS since this is now done in tcl.m4.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Document and
	set CC_SEARCH_FLAGS whenever LD_SEARCH_FLAGS is set.
	[Tcl patch 588290]

2002-07-29  Reinhard Max  <max@suse.de>

	* unix/tcl.m4 (SC_SERIAL_PORT): Fixed detection for cases when
                                        configure's stdin is not a tty.
	
	* unix/tclUnixPort.h: 
	* generic/tclIOSock.c:          Changed size_t to socklen_t in
                                        socket-related function calls.

	* unix/configure.in:            Added test and fallback definition
                                        for socklen_t.
	
	* unix/configure:               generated.

2002-07-29  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclObj.c: fixed a comment

	* generic/tcl.h: 
	* generic/tclBasic.c: 
	* generic/tclInterp.c: added the new flag TCL_EVAL_INVOKE to
	the interface of the Tcl_Eval* functions, removing the
	TCL_EVAL_NO_TRACEBACK added yesterday: alias invocations not only 
	require no tracebacks, but also look up the command name in the
	global scope - see new test interp-9.4
	* tests/interp.test: added 9.3 to test for safety of aliases to
	hidden commands, 9.4 to test for correct command lookup scope.

2002-07-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/regc_locale.c (cclass): [[:xdigit:]] is only a defined
	concept on western characters, so should not allow any unicode
	digit, and hence number of ranges in [[:xdigit:]] is fixed.
	* tests/reg.test: Added test to detect the bug.
	* generic/regc_cvec.c (newcvec): Corrected initial size value in
	character vector structure.  [Bug 578363]  Many thanks to
	pvgoran@users.sf.net for tracking this down.

2002-07-28  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tcl.h: 
	* generic/tclBasic.c: added the new flag TCL_EVAL_NO_TRACEBACK to
	the interface of the Tcl_Eval* functions. Modified the error
	message for too many nested evaluations.
	* generic/tclInterp.h: changed the Alias struct to be of variable
	length and store the prefix arguments directly (instead of a
	pointer to a Tcl_Obj list). Made AliasObjCmd call Tcl_EvalObjv
	instead of TclObjInvoke - thus making aliases trigger execution
	traces [Bug 582522].
	* tests/interp.test:
	* tests/stack.test: adapted to the new error message.
	* tests/trace.test: added tests for aliases firing the exec
	traces. 

2002-07-27  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in: Revert fix for Tcl bug 529801
	since it was incorrect and broke the build on
	other systems. Fix Tcl bug 587299.
	Add MAJOR_VERSION, MINOR_VERSION, PATCH_LEVEL,
	SHLIB_LD_FLAGS, SHLIB_LD_LIBS, CC_SEARCH_FLAGS,
	LD_SEARCH_FLAGS, and LIB_FILE variables to support
	more generic library build/install rules.
	* unix/configure: Regen.
	* unix/configure.in: Move AC_PROG_RANLIB into
	tcl.m4. Move shared build test and setting
	of MAKE_LIB and MAKE_STUB_LIB into tcl.m4.
	Move subst of a number of variables into
	tcl.m4 where they are defined.
	* unix/tcl.m4 (SC_ENABLE_SYMBOLS, SC_CONFIG_CFLAGS):
	Subst vars where they are defined. Add MAKE_LIB,
	MAKE_STUB_LIB, INSTALL_LIB, and INSTALL_STUB_LIB
	rules to deal with the ugly details of running
	ranlib on static libs at build and install time.
	Replace TCL_SHLIB_LD_EXTRAS with SHLIB_LD_FLAGS
	and use it when building a shared library.
	* unix/tclConfig.sh.in: Add TCL_CC_SEARCH_FLAGS.

2002-07-26  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: fixed Tcl_Obj leak in code corresponding
	to the macro NEXT_INST_V(x, 0, 1) [Bug 587495].
	
2002-07-26  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclVar.c (TclObjLookupVar): leak fix and improved
	comments. 

2002-07-26  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclVar.c (TclLookupVar): removed early returns that
	prevented the parens from being restored. also removed goto label
	as it was not necessary.

2002-07-24  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: 
	* tests/expr-old.test: fix for erroneous error messages in [expr],
	[Bug  587140] reported by Martin Lemburg.

2002-07-25  Joe English  <jenglish@users.sourceforge.net>
	* generic/tclProc.c: fix for Tk Bug #219218 "error handling 
	with bgerror in Tk"

2002-07-24  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: restoring full TCL_COMPILE_DEBUG
	functionality.

2002-07-24  Don Porter  <dgp@users.sourceforge.net>

	* tests/unixInit.test: relaxed unixInit-3.1 to accept iso8859-15
	as a valid C encoding.  [Bug 575336]

2002-07-24  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: restoring the tcl_traceCompile
	functionality while I repair tcl_traceExec. The core now compiles
	and runs also under TCL_COMPILE_DEBUG, but execution in the
	bytecode engine can still not be traced.

2002-07-24  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in:
	* unix/configure.in: corrected fix for [Bug 529801]: ranlib
	only needed for static builds on Mac OS X.
	* unix/configure: Regen.
	* unix/tclLoadDyld.c: fixed small bugs introduced by Vince,
	implemented library unloading correctly (needs OS X 10.2).

2002-07-23  Joe English  <jenglish@users.sourceforge.net>

	* doc/OpenFileChnl.3: (Updates from Larry Virden)
	* doc/open.n:
	* doc/tclsh.1: Fix section numbers in Unix man page references.
	* doc/lset.n:  In EXAMPLES section, include command to set the 
	initial value used in subsequent examples.
	* doc/http.n: Package version updated to 2.4.

2002-07-23  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Enable 64 bit compilation
	when using the native compiler on a 64 bit version of IRIX.
	[Tcl bug 219220]

2002-07-23  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in: Combine ranlib tests and
	avoid printing unless ranlib is actually run.

2002-07-23  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/tcl.m4 (SC_PATH_X): Set XINCLUDES to "" instead
	of "# no special path needed" or "# no include files found"
	when x headers cannot be located.

2002-07-22  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: made tclNativeFilesystem static
	(since 07-19 changes removed its usage elsewhere), and
	added comments about its usage.
	* generic/tclLoad.c:
	* generic/tcl.h:
	* generic/tcl.decls: 
	* doc/FileSystem.3: converted last load-related ClientData
	parameter to Tcl_LoadHandle opaque structure, removing a 
	couple of casts in the process.
	
	* generic/tclInt.h: removed tclNativeFilesystem declaration
	since it is now static again.
	
2002-07-22  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/expr.test (expr-22.*): Added tests to help detect the
	corrected handling.
	* generic/tclExecute.c (IllegalExprOperandType): Improved error
	message generated when attempting to manipulate Inf and NaN values.
	* generic/tclParseExpr.c (GetLexeme): Allowed parser to recognise
	'Inf' as a floating-point number. [Bug 218000]

2002-07-21  Don Porter  <dgp@users.sourceforge.net>

	* tclIOUtil.c: Silence compiler warning. [Bug 584408].

2002-07-19  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: fix to GetFilesystemRecord
	* win/tclWinFile.c:
	* unix/tclUnixFile.c: fix to subtle problem with links shown
	up by latest tclkit builds.

2002-07-19  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure:
	* unix/configure.in:
	* win/configure:
	* win/configure.in: Add AC_PREREQ(2.13) in an attempt
	to make it more clear that the configure scripts
	must be generated with autoconf version 2.13.
	[Bug 583573]

2002-07-19  Vince Darley  <vincentdarley@users.sourceforge.net>

	* unix/Makefile.in: fix to build on MacOS X [Bug 529801], bug
	report and fix from jcw.

2002-07-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* win/tclWinSerial.c (no_timeout): Made this variable static.

	* generic/tclExecute.c, generic/tclCompile.c, generic/tclBasic.c: 
	* generic/tclCompile.h (builtinFuncTable, instructionTable): Added
	prefix to these symbols because they are visible outside the Tcl
	library.

	* generic/tclCompExpr.c (operatorTable): 
	* unix/tclUnixTime.c (tmKey):
	* generic/tclIOUtil.c (theFilesystemEpoch, filesystemWantToModify,
	filesystemIteratorsInProgress, filesystemOkToModify): Made these
	variables static.

	* unix/tclUnixFile.c:		Renamed nativeFilesystem to
	* win/tclWinFile.c:		tclNativeFilesystem and declared
	* generic/tclIOUtil.c:		it properly in tclInt.h
	* generic/tclInt.h: 

	* generic/tclUtf.c (totalBytes): Made this array static and const.

	* generic/tclParse.c (typeTable): Made this array static and const.
	(Tcl_ParseBraces): Simplified error handling case so that scans
	are only performed when needed, and flags are simpler too.

	* license.terms: Added AS to list of copyright holders; it's only
	fair for the current gatekeepers to be listed here!

	* tests/cmdMZ.test: Renamed constraint for clarity. [Bug#583427]
	Added tests for the [time] command, which was previously only
	indirectly tested!

2002-07-18  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclInt.h:
	* generic/tcl.h:
	* */*Load*.c: added comments on changes of 07/17 and 
	replaced clientData with Tcl_LoadHandle in all locations.

	* generic/tclFCmd.c:
	* tests/fileSystem.test: fixed a 'knownBug' with 'file
	attributes ""'
	* tests/winFCmd.test: 
	* tests/winPipe.test:
	* tests/fCmd.test:
	* tessts/winFile.test: added 'pcOnly' constraint to some
	tests to make for more useful 'tests skipped' log from 
	running all tests on non-Windows platforms.
	
2002-07-17  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c (CallCommandTraces): delete traces now
	receive the FQ old name of the command. 
	[Bug 582532] (Don Porter)

2002-07-18  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/ioUtil.test: added constraints to 1.4,2.4 so they
	don't run outside of tcltest. [Bugs 583276,583277]
	
2002-07-17  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclVar.c (DupParsedVarName): nasty bug fixed, reported
	by Vince Darley.

2002-07-17  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclVar.c (TclPtrIncrVar): missing CONST in declarations,
	inconsistent with tclInt.h. Thanks to Vince Darley for reporting,
	boo to gcc for not complaining.
	
2002-07-17  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclInt.h:
	* generic/tclIOUtil.c:
	* generic/tclLoadNone.c:
	* unix/tclLoadAout.c:
	* unix/tclLoadDl.c:
	* unix/tclLoadDld.c:
	* unix/tclLoadDyld.c:
	* unix/tclLoadNext.c:
	* unix/tclLoadOSF.c:
	* unix/tclLoadShl.c:
	* mac/tclMacLoad.c:
	* win/tclWinLoad.c: modified to move more functionality
	to the generic code and avoid duplication.  Partial replacement
	of internal uses of clientData with opaque Tcl_LoadHandle.  A
	little further work still needed, but significant changes are done.

2002-07-17  D. Richard Hipp    <drh@hwaci.com>

	* library/msgcat/msgcat.tcl: fix a comment that was causing
	problems for programs (ex: mktclapp) that embed the initialization
	scripts in strings.

2002-07-17  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclInt.decls:
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c:
	* generic/tclVar.c: removing the now redundant functions to access
	indexed variables: Tcl(Get|Set|Incr)IndexedScalar() and
	Tcl(Get|Set|Incr)ElementOfIndexedArray(). 

2002-07-17  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): Minor fixes to make
	this file compile with SunPro CC...

2002-07-17  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: modified to do variable lookup explicitly,
	and then either inlining the variable access or else calling the new
	TclPtr(Set|Get|Incr)Var functions in tclVar.c
	* generic/tclInt.h: declare some functions previously local to
	tclVar.c for usage by TEBC.
	* generic/tclVar.c: removed local declarations; moved all special
	accessor functions for indexed variables to the end of the file -
	they are unused and ready for removal, but left there for the time
	being as they are in the internal stubs table.

	** WARNING FOR BYTECODE MAINTAINERS **
	TCL_COMPILE_DEBUG is currently not functional; will be fixed ASAP.
	
2002-07-16  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in:
	* win/Makefile.in: Add a more descriptive warning
	in the event `make genstubs` needs to be rerun.

2002-07-16  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in: Use dltest.marker file
	to keep track of when the dltest package
	is up to date. This fixes [Tcl bug 575768]
	since tcltest is no longer linked every time.
	* unix/dltest/Makefile.in: Create ../dltest.marker
	after a successful `make all` run in dltest.

2002-07-16  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/configure.in: Remove useless subst of TCL_BIN_DIR.

2002-07-15  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclVar.c: inaccurate comment fixed
	
2002-07-15  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_AddObjErrorInfo):
	* generic/tclExecute.c (TclUpdateReturnInfo):
	* generic/tclInt.h:	
	* generic/tclProc.c: 
	Added two Tcl_Obj to the ExecEnv structure to hold the fully
	qualified names "::errorInfo" and "::errorCode" to cache the
	addresses of the corresponding variables. The two most frequent
	setters of these variables now profit from the new variable name
	caching. 

2002-07-15  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclVar.c: refactorisation to reuse already looked-up Var
	pointers; definition of three new Tcl_Obj types to cache variable
	name parsing and lookup for later reuse; modification of internal
	functions to profit from the caching. 
	
	* generic/tclInt.decls:
	* generic/tclInt.h:
	* generic/tclIntDecls.h:
	* generic/tclNamesp.c: adding CONST qualifiers to variable names
	passed to Tcl_FindNamespaceVar and to variable resolvers; adding
	CONST qualifier to the 'msg' argument to TclLookupVar. Needed to
	avoid code duplication in the new tclVar.c code.

	* tests/set-old.test:
	* tests/var.test: slight modification of error messages due to the
	modifications in the tclVar.c code.

2002-07-15  Don Porter  <dgp@users.sourceforge.net>

	* tests/unixInit.test:	Improved constraints to protect /tmp.	
	  [Bug 581403]

2002-07-15  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/winFCmd.test: renamed 'win2000' and 'notWin2000' to
	more appropriate constraint names.
	* win/tclWinFile.c: updated comments to reflect 07-11 changes.
	* win/tclWinFCmd.c: made ConvertFileNameFormat static again,
	since no longer used in tclWinFile.c
	* mac/tclMacFile.c: completed TclpObjLink implementation which
	was previously lacking.
	* generic/tclIOUtil.c: comment cleanup and code speedup.
	
2002-07-14  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.h:	Removed declarations that duplicated entries
	  in the (internal) stub table.
	
	* library/tcltest/tcltest.tcl:  Corrected errors in handling of
	  configuration options -constraints and -limitconstraints.

	* README:		Bumped HEAD to version 8.4b2 so we can
	* generic/tcl.h:	distinguish it from the 8.4b1 release.
	* tools/tcl.wse.in:
	* unix/configure*:
	* unix/tcl.spec:
	* win/README.binary:
	* win/configure*:

2002-07-11  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/file.n:
	* win/tclWinFile.c: on Win 95/98/ME the long form of the path
	is used as a normalized form.  This is required because short
	forms are not a robust representation.  The file normalization
	function has been sped up, but more performance gains might be
	possible, if speed is still an issue on these platforms.

2002-07-11  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl: Corrected reaction to existing but
	false ::tcl_interactive.

	* doc/Hash.3: Overlooked CONST documentation update.

2002-07-11  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCkalloc.c: ckalloc() and friends take the block size
	as an unsigned, so we should use %ud when reporting it in fprintf()
	and panic().

2002-07-11  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompile.c: now setting local vars undefined at
	compile time, instead of waiting until the proc is initialized. 
	* generic/tclProc.c: use macro TclSetVarUndefined instead of
	directly etting the flag.

2002-07-11  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/cmdAH.test: [file attr -perm] is Unix-only, so add [catch]
	when not inside a suitably-protected test.

2002-07-10  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/unixFCmd.test, tests/fileName.test: 
	* tests/fCmd.test: Removed [exec] of Unix utilities that have
	equivalents in standard Tcl.  [Bug 579268]  Also simplified some
	of unixFCmd.test while I was at it.

2002-07-10  Don Porter  <dgp@users.sourceforge.net>

	* tests/tcltest.test:  Greatly reduced the number of [exec]s, using
	slave interps instead.
	* library/tcltest/tcltest.tcl:  Fixed bug uncovered in the conversion
	where a message was written to stdout instead of [outputChannel].

	* tests/basic.test:	Cleaned up, constrained, and reduced the
	* tests/compile.test:	amount of [exec] usage in the test suite.
	* tests/encoding.test:
	* tests/env.test:
	* tests/event.test:

2002-07-10  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/cmdAH.test: Removed [exec] of Unix utilities. [Bug 579211]

	* tests/expr.test: Added tests to make sure that this works.
	* generic/tclExecute.c (ExprCallMathFunc): Functions should also
	be able to return wide-ints.  [Bug 579284]

2002-07-08  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* tests/socket.test: Fixed bug #578164. The original reason for
	  the was a DNS outage while running the testsuite. Changed [info
	  hostname] to 127.0.0.1 to bypass DNS, knowing that we operate on
	  the local host.

2002-07-08  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n:		Fixed incompatibility in [viewFile].
	* library/tcltest/tcltest.tcl:	Corrected docs.  Bumped to 2.2.1.
	* library/tcltest/pkgIndex.tcl: [Bug 578163]

2002-07-08  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/cmdAH.test:
	* tests/fCmd.test:
	* tests/fileName.test: tests which rely on 'file link' need a
	constraint so they don't run on older Windows OS. [Bug 578158]

	* generic/tclInt.h:
	* generic/tclTest.c:
	* mac/tclMacChan.c:
	* unix/tclUnixChan.c:
	* win/tclWinChan.c:
	* doc/FileSystem.3: cleaned up internal handling of
	Tcl_FSOpenFileChannel to remove duplicate code, and make
	writing external vfs's clearer and easier.  No
	functionality change.  Also clarify that objects with refCount
	zero should not be passed in to the Tcl_FS API, and prevent
	segfaults from occuring on such user errors. [Bug 578617]
	
2002-07-06  Don Porter  <dgp@users.sourceforge.net>

	* tests/pkgMkIndex.test:  Constrained tests of [load] package indexing
	to those platforms where the testing shared libraries have been built.

	* changes: added recent changes

2002-07-05  Reinhard Max  <max@suse.de>

	* generic/tclClock.c (FormatClock): Convert the format string to
	UTF8 before calling TclpStrftime, so that non-ASCII characters
	don't get mangled when the result string is being converted back.
	* tests/clock.test: Added a test for that.

2002-07-05  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* unix/Makefile.in (ro-test,ddd,GDB,DDD): Created new targets to
	allow running the test suite with a read-only current directory,
	running under ddd instead of gdb, and factored out some executable
	names for broken sites (like mine) where gdb and ddd are installed
	with non-standard names...

	* tests/httpold.test: Altered test names to httpold-* to avoid
	clashes with http.test, and stopped tests from failing when the
	current directory is not writable...

	* tests/event.test:		Stop these tests from failing
	* tests/ioUtil.test:		when the current directory is

	* tests/winPipe.test: 
	* tests/pid.test: Fixed SF Bug #575848. See below for a
	  description the general problem.

	  pkg].  Part of the fix was to import several auxilliary files
	  into the test file itself.

	* tests/main.test:	Cheap fix for [Bugs 575851, 575858].  Avoid
	* tests/tcltest.test:	non-writable . by [cd [temporaryDirectory]].

	* library/auto.tcl: Fix [tcl_findLibrary] to be sure it sets
	  $varName only if a successful library script is found.
	  [Bug 577033]

2002-07-03  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileCatchCmd): return
	  TCL_OUT_LINE_COMPILE instead of TCL_ERROR: let the failure
	  happen at runtime so that it can be caught [Bug 577015].

2002-07-02  Joe English  <jenglish@users.sourceforge.net>

	* doc/tcltest.n: Markup fixes, spellcheck.

2002-07-02  Don Porter  <dgp@users.sourceforge.net>

	* tests/event.test:		procedure.  Restored tests.
	* tests/http.test:
	* tests/io.test:

	* library/tcltest/tcltest.tcl: Simplified logic of
	  [GetMatchingFiles] and [GetMatchingDirectories], removing
	  special case processing.

	* doc/tcltest.n: More documentation updates.  Reference sections
	  are complete.  Only examples need adding.

2002-07-02  Vince Darley  <vincentdarley@users.sourceforge.net>

2002-07-01  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Made Solaris use gcc for linking
	when building with gcc to resolve problems with undefined symbols
	being present when tcl library used with non-gcc linker at later
	stage. Symbols were compiler-generated, so it is the compiler's
	business to define them. [Bug #541181] 

2002-07-01  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n: more work in progress updating tcltest docs.

	* library/tcltest/tcltest.tcl: Change [configure -match] to
	stop treating an empty list as a list of the single pattern "*".
	Changed the default value to [list *] so default operation
	remains the same.

	* tests/pkg/samename.tcl: restored.  needed by pkgMkIndex.test.

	* library/tcltest/tcltest.tcl: restored writeability testing of
	-tmpdir, augmented by a special exception for the deafault value.

2002-07-01  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/concat.n: Documented the *real* behaviour of [concat]!

2002-06-30  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n: more work in progress updating tcltest docs.

	* tests/README:		Updated the instructions on running and
	* tests/cmdMZ.test:	adding to the test suite.  Also updated
	* tests/encoding.test:	several tests, mostly to correctly create
	* tests/fCmd.test:	and destroy any temporary files in the
	* tests/info.test:	[temporaryDirectory] of tcltest.
	* tests/interp.test:

	* library/tcltest/tcltest.tcl:	Stopped checking for writeability
	of -tmpdir value because no default directory can be guaranteed to
	be writeable.

	* tests/autoMkindex.tcl: removed.
	* tests/pkg/samename.tcl: removed.
	* tests/pkg/magicchar.tcl: removed.
	* tests/pkg/magicchar2.tcl: removed.
	* tests/autoMkindex.test: Updated auto_mkIndex tests to use
	[makeFile] and [removeFile] so tests are done in [temporaryDirecotry]
	where write access is guaranteed.

	* library/tcltest/tcltest.tcl:	Fixed [makeFile] and [viewFile] to
	* tests/cmdAH.test:		accurately reflect a file's contents.
	* tests/event.test:		Updated tests that depended on buggy
	* tests/http.test:		behavior.  Also added warning messages
	* tests/io.test:		to "-debug 1" operations to debug test
	* tests/iogt.test:		calls to (make|remove)(File|Directory).

	* unix/mkLinks: `make mklinks` on 6-27 commits.

2002-06-28  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompile.h: modified the macro TclEmitPush to not
	call its first argument repeatedly or pass it to other macros,
	[Bug 575194] reported by Peter Spjuth.

2002-06-28  Don Porter  <dgp@users.sourceforge.net>

	* docs/tcltest.n:	Doc revisions in progress.

	Was not reliable, and disagreed with docs!  Thanks to Hemang Lavana.
	[Bug 575150]

2002-06-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* unix/tclUnixThrd.c:	Renamed the Tcl_Platform* #defines to
	* unix/tclUnixPipe.c:	TclOS* because they are only used
	* unix/tclUnixFile.c:	internally.  Also stopped double-#def
	* unix/tclUnixFCmd.c:	of TclOSlstat [Bug #566099, post-rename]
	* unix/tclUnixChan.c:
	* unix/tclUnixPort.h:

	* doc/string.n: Improved documentation for [string last] along
	lines described in Bug #574799 so it indicates that the supplied
	index marks the end of the search space.

2002-06-27  Don Porter  <dgp@users.sourceforge.net>

	* doc/dde.n:		Work in progress updating the documentation

	* doc/registry.n:
	* doc/tcltest.n:

	Ensure good error messages are given in all cases.
	* tests/cmdAH.test:
	* unix/tclUnixFCmd.c: fix to bug reported as part of

	#500930. 
	
2002-06-24  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:	Corrected suppression of -verbose skip
	* tests/tcltest.test:		and start by [test -output].  Also
	corrected test suite errors exposed by corrected code.  [Bug 564656]

2002-06-25  Reinhard Max  <max@suse.de>

	* unix/tcl.m4:       New macro SC_CONFIG_MANPAGES.
	* unix/configure.in: Added support for symlinks and compression
	* unix/Makefile.in:  when installing the manpages. [Patch 518052]
	* unix/mkLinks.tcl:  Default is still hardlinks and no compression.

	* unix/mkLinks:      generated
	* unix/configure:

	* unix/README:       Added documentation for the new features.

	* unix/tcl.m4 (SC_PATH_TCLCONFIG): Replaced ${exec_prefix}/lib by
	${libdir}.

2002-06-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclUtil.c (TclGetIntForIndex): Fix of critical bug
	#533364 generated when the index is bad and the result is a shared
	object.  The T_ASTO(T_GOR, ...) idiom likely exists elsewhere
	though.  Also removed some cruft that just complicated things to
	no advantage.
	(SetEndOffsetFromAny): Same fix, though this wasn't on the path
	excited by the bug.

2002-06-24  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:	Implementation of TIP 101.  Adds
	* tests/parseOld.test:		and exports a [configure] command
	* tests/tcltest.test:		from tcltest.

2002-06-22  Don Porter  <dgp@users.sourceforge.net>

	* changes: updated changes file for 8.4b1 release.

	* library/tcltest/tcltest.tcl:	Corrections to tcltest and the
	* tests/basic.test:		Tcl test suite so that a test
	* tests/cmdInfo.test:		with options -constraints knownBug
	* tests/compile.test:		-limitConstraints 1 only tests the
	* tests/encoding.test:		knownBug tests.  Mostly involves
	* tests/env.test:		replacing direct access to the
	* tests/event.test:		testConstraints array with calls
	* tests/exec.test:		to the testConstraint command
	* tests/execute.test:		(which requires tcltest version 2)

	* win/makefile.vc:	to installation on Windows.

	* library/init.tcl:  Corrected comments and namespace style
	issues.  Thanks to Bruce Stephens. [Bug 572025]

2002-06-21  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/cmdAH.test:          Added TIP#99 implementation
	* tests/fCmd.test:           of 'file link'.  Supports creation
	* tests/fileName.test:       of symbolic and hard links in the
	* tests/fileSystem.test:     native filesystems and in vfs's,
	* generic/tclTest.c:         when the individual filesystem
	* generic/tclCmdAH.c:        supports the concept.

	* doc/FileSystem.3:
	* doc/file.n:

2002-06-20  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c (TclEvalObjvInternal): fix for [Bug 571385]
	in the implementation of TIP#62 (command tracing). Vince Darley,
	Hemang Lavana & Don Porter: thanks.

2002-06-20  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c (TclCompEvalObj): clarified and simplified
	the logic for compilation/recompilation.

2002-06-19  Joe English  <jenglish@users.sourceforge.net>
	* doc/file.n: Fixed indentation.  No substantive changes.

2002-06-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd): get the resultPtr again
	as the Tcl_ObjSetVar2 may cause the result to change.
	[Patch #558324] (watson)

2002-06-19  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c (TEBC): removing unused "for(;;)" loop;
	improved comments; re-indentation.

2002-06-18  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c (TEBC): 
	- elimination of duplicated code in the non-immediate INST_INCR
	  instructions. 
	- elimination of 103 (!) TclDecrRefCount macros. The different
	  instructions now jump back to a common "DecrRefCount zone" at
	  the top of the loop. The macro "ADJUST_PC" was replaced by two
	  macros "NEXT_INST_F" and "NEXT_INST_V" that take three params
	  (pcAdjustment, # of stack objects to discard, resultObjPtr
	  handling flag). The only instructions that retain a
	  TclDecrRefCount are INST_POP (for speed), the common code for
	  the non-immediate INST_INCR, INST_FOREACH_STEP and the two
	  INST_LSET.

	The object size of tclExecute.o was reduced by approx 20% since
	the start of the consolidation drive, while making room for some
	peep-hole optimisation at runtime.

2002-06-18  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c (TEBC, INST_DONE): small bug in the panic
	code for tcl-stack corruption.

2002-06-17  David Gravereaux <davygrvy@pobox.com>

	Trims to support the removal of RESOURCE_INCLUDED from rc
	scripts	from FR #565088.

	* generic/tcl.h: moved the #ifndef RC_INVOKED start block up in
	the file.  rc scripts don't need to know thread mutexes.

	* win/tcl.rc:
	* win/tclsh.rc: removed the #define RESOURCE_INCLUDED to let the
	built-in -DRC_INVOKED to the work.

2002-06-17  Jeff Hobbs  <jeffh@ActiveState.com>

	* doc/CrtTrace.3:        Added TIP#62 implementation of command
	* doc/trace.n:           execution tracing [FR #462580] (lavana).
	* generic/tcl.h:         This includes enter/leave tracing as well

	* win/tclWinPipe.c (BuildCommandLine): Fixed bug #554068 ([exec]
	  on windows did not treat { in filenames well.). Bug reported by
	  Vince Darley <vincentdarley@users.sourceforge.net>, patch
	  provided by Vince too.

2002-06-17  Joe English  <jenglish@users.sourceforge.net>

	* generic/tcl.h: #ifdef logic for K&R C backwards compatibility
	changed to assume modern C by default.  See SF FR #565088 for
	full details.

2002-06-17  Don Porter  <dgp@users.sourceforge.net>

	* doc/msgcat.n: Corrected en_UK references to en_GB.  UK is not
	a country designation recognized in ISO 3166.

	* library/msgcat/msgcat.tcl:  More Windows Registry locale codes
	from Bruno Haible.

	* doc/msgcat.n:
	* library/msgcat/msgcat.tcl:
	* library/msgcat/pkgIndex.tcl:
	* tests/msgcat.test:  Revised locale initialization to interpret
	environment variable locale values according to XPG4, and to
	recognize the LC_ALL and LC_MESSAGES values over that of LANG.
	Also added many Windows Registry locale values to those 
	recognized by msgcat.  Revised tests and docs.  Bumped to
	version 1.3.  Thanks to Bruno Haible for the report and
	assistance crafting the solution.  [Bug 525522, 525525]

2002-06-16  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompile.c (TclCompileTokens): a better algorithm for
	the previous bug fix.

2002-06-16  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompile.c (TclCompileTokens): 
	* tests/compile.test: [Bug 569438] in the processing of dollar
	variables; report by Georgios Petasis. 
	
2002-06-16  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: bug in the consolidation of the
	INCR_..._STK instructions; the bug could not be exercised as the
	(faulty) instruction INST_INCR_ARRAY_STK was never compiled-in
	(related to [Bug 569438]).

2002-06-14  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c (TclExecuteByteCode): runtime peep-hole
	optimisation of variables (INST_STORE, INST_INCR) and commands
	(INST_INVOKE); faster check for the existence of a catch.
	(TclExecuteByteCode): runtime peep-hole optimisation of
	comparisons.
	(TclExecuteByteCode): runtime peep-hole optimisation of
	INST_FOREACH - relies on peculiarities of the code produced by the
	bytecode compiler.

2002-06-14  David Gravereaux <davygrvy@pobox.com>

	* win/rules.vc: The test for compiler optimizations was in error.
	Thanks goes to Roy Terry <royterry@earthlink.net> for his
	assistance with this.

2002-06-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/trace.n, tests/trace.test: 
	* generic/tclCmdMZ.c (Tcl_TraceObjCmd,TclTraceCommandObjCmd)
	(TclTraceVariableObjCmd): Changed references to "trace list" to
	"trace info" as mandated by TIP#102.

2002-06-13  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c (TclExecuteByteCode): consolidated code for
	the conditional branch instructions.

2002-06-13  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c (TclExecuteByteCode): fixed the previous
	patch - wouldn't compile with TCL_COMPILE_DEBUG set.

2002-06-13  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c (TclExecuteByteCode): consolidated the
	handling of exception returns to INST_INVOKE and INST_EVAL, as
	well as most of the code for INST_CONTINUE and INST_BREAK, in the
	new jump target "processExceptionReturn".

2002-06-13  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c (TclExecuteByteCode): consolidated variable
	handling opcodes, replaced redundant code with some 'goto'. All
	store/append/lappend opcodes on the same data type now share the
	main code; same with incr opcodes.
	* generic/tclVar.c: added the bit TCL_TRACE_READS to the possible
	flags to Tcl_SetVar2Ex - it causes read traces to be fired prior
	to setting the variable. This is used in the core for [lappend].

	***NOTE*** the usage of TCL_TRACE_READS in Tcl_(Obj)?GetVar.* is
	not documented; there, it causes the call to create the variable
	if it does not exist. The new usage in Tcl_(Obj)?SetVar.* remains
	undocumented too ...
	
2002-06-13  Vince Darley  <vincentdarley@users.sourceforge.net>

	* tests/fCmd.test:
	* tests/winFile.test:
	* tests/fileSystem.test:
	* generic/tclTest.c:
	* generic/tclCmdAH.c:
	* generic/tclIOUtil.c:
	* doc/FileSystem.3:
	* mac/tclMacFile.c:
	* unix/tclUnixFile.c:
	* win/tclWinFile.c: fixed up further so both compiles and
	actually works with VC++ 5 or 6.
	* win/tclWinInt.h: 
	* win/tclWin32Dll.c: cleaned up code and vfs tests and
	added tests for the internal changes of 2002-06-12, to see
	whether WinTcl on NTFS can coexist peacefully with links
	in the filesystem.  Added new test command 'testfilelink'
	to enable the newer code to be tested.
	* tests/fCmd.test: (made certain tests of 'testfilelink' not
	run on unix).

2002-06-12  Miguel Sofer  <msofer@users.sourceforge.net>

	* tclBasic.c (Tcl_DeleteTrace): fixed [Bug 568123] (thanks to
	Hemang Lavana)
	
2002-06-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinFile.c: corrected the symbolic link handling code to
	allow it to compile.  Added real definition of REPARSE_DATA_BUFFER
	(found in winnt.h).  Most of the added definitions appear to have
	correct, cross-Win-version equivalents in winnt.h and should be
	removed, but just making things "work" for now.

2002-06-12  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c:
	* generic/tcl.decls:
	* generic/tclDecls.h: made code for Tcl_FSNewNativePath
	agree with man pages.
	
	* doc/FileSystem.3: clarified the circumstances under which
	certain functions are called in the presence of symlinks.
	
	* win/tclWinFile.c:
	* win/tclWinPort.h: 
	* win/tclWinInt.h: 
	* win/tclWinFCmd.c:  Fix for Windows to allow 'file lstat', 
	'file type', 'glob -type l', 'file copy', 'file delete', 
	'file normalize', and all VFS code to work correctly in the 
	presence of symlinks (previously Tcl's behaviour was not very 
	well defined).  This also fixes possible serious problems in 
	all versions of WinTcl where 'file delete' on a NTFS symlink 
	could delete the original, not the symlink.
	Note: symlinks cannot yet be created in pure Tcl.

2002-06-11  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c: 
	* generic/tclCompCmds.c:
	* generic/tclInt.h: reverted the new compilation functions;
	replaced by a more general approach described below.

	* generic/tclCompCmds.c:
	* generic/tclCompile.c: made *all* compiled variable access
	attempts create an indexed variable - even get or incr without
	previous set. This allows indexed access to local variables that
	are created and set at runtime, for example by [global], [upvar],
	[variable], [regexp], [regsub].

2002-06-11  Miguel Sofer  <msofer@users.sourceforge.net>

	* doc/global.n:
	* doc/info.n:
	* test/info.test:
	* generic/tclCmdIL.c: fix for [Bug 567386], [info locals] was
	reporting some linked variables.
	
	* generic/tclBasic.c: 
	* generic/tclCompCmds.c:
	* generic/tclInt.h: added compile functions for [global],
	[variable] and [upvar]. They just declare the new local variables,
	the commands themselves are not compiled-in. This gives a notably
	faster read access to these linked variables.

2002-06-11  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: optimised algorithm for exception range
	lookup; part of [Patch 453709].

2002-06-10  Vince Darley  <vincentdarley@users.sourceforge.net>

	* unix/tclUnixFCmd.c: fixed [Bug #566669]
	* generic/tclIOUtil.c: improved and sped up handling of
	native paths (duplication and conversion to normalized paths),
	particularly on Windows.
	* modified part of above commit, due to problems on Linux. 
	Will re-examine bug report and evaluate more closely.

2002-06-07  Don Porter  <dgp@users.sourceforge.net>

	* tests/tcltest.test:  More corrections to test suite so that tests
	of failing [test]s don't show up themselves as failing tests.

2002-06-07  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclExecute.c: Tidied up headers in relation to float.h
	to cut the cruft and ensure DBL_MAX is defined since doubles seem
	to be the same size everywhere; if the assumption isn't true, the
	variant platforms had better have run configure...

	* unix/tclUnixPort.h (EOVERFLOW): Added code to define it if it
	wasn't previously defined.  Also some other general tidying and
	adding of comments.  [Tcl bugs 563122, 564595]
	* compat/tclErrno.h: Added definition for EOVERFLOW copied from
	Solaris headers; I've been unable to find any uses of EFTYPE,
	which was the error code previously occupying the slot, in Tcl, or
	any definition of it in the Solaris headers.

2002-06-06  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/dltest/Makefile.in: Remove hard coded CFLAGS=-g
	and add CFLAGS_DEBUG, CFLAGS_OPTIMIZE, and
	CFLAGS_DEFAULT varaibles. [Tcl bug 565488]

2002-06-06  Don Porter  <dgp@users.sourceforge.net>

	* tests/tcltest.test:  Corrections to test suite so that tests
	of failing [test]s don't show up themselves as failing tests.

	* tests/io.test: Fixed up namespace variable resolution issues
	revealed by running test suite with "-singleproc 1".

	* doc/tcltest.n:
	* library/tcltest/tcltest.tcl:
	* tests/tcltest.test: Several updates to tcltest.
	  1) changed to lazy initialization of test constraints
	  2) deprecated [initConstraintsHook]
	  3) repaired badly broken [limitConstraints].
	  4) deprecated [threadReap] and [mainThread]
	[Patch 512214, Bug 558742, Bug 461000, Bug 534903]

2002-06-06  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixThrd.c (TclpReaddir, TclpLocaltime, TclpGmtime):
	added mutex wrapped calls to readdir, localtime & gmtime in
	case their thread-safe *_r counterparts are not available.
	* unix/tcl.m4: added configure check for readdir_r
	* unix/tcl.m4 (Darwin): set TCL_DEFAULT_ENCODING to utf-8 on
	MacOSX (where posix file apis expect utf-8, not iso8859-1).   
	* unix/configure: regen
	* unix/Makefile.in: set DYLD_LIBRARY_PATH in parallel       
	to LD_LIBRARY_PATH for MacOSX dynamic linker.
	* generic/tclEnv.c (TclSetEnv): fix env var setting on
	MacOSX (adapted from patch #524352 by jkbonfield).

2002-06-05  Don Porter  <dgp@users.sourceforge.net>

	* doc/Tcl_Main.3: Documented $tcl_rcFileName and added more
	clarifications about the intended use of Tcl_Main(). [Bug 505651]

2002-06-05  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclFileName.c (TclGlob): mac specific fix to
	recent changes in 'glob -tails' handling.
	* mac/tclMacPort.h:
	* mac/tclMacChan.c: fixed TIP#91 bustage.
	* mac/tclMacResource.c (Tcl_MacConvertTextResource): added utf
	conversion of text resource contents.
	* tests/macFCmd.test (macFCmd-1.2): allow CWIE creator.

2002-06-04  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:
	* tests/init.test:
	* tests/tcltest.test:	Added more TIP 85 tests from Arjen Markus.
	Converted tcltest.test to use a private namespace.  Fixed bugs in
	[tcltest::Eval] revealed by calling [tcltest::test] from a non-global
	namespace, and namespace errors in init.test.

2002-06-04  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/README: Update msys+mingw URL.

2002-06-03  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n:
	* library/tcltest/tcltest.tcl:
	* library/tcltest/pkgIndex.tcl:
	* tests/tcltest.test:  Implementation of TIP 85.  Allows tcltest
	users to add new legal values of the -match option to [test],
	associating each with a Tcl command that does the matching of
	expected results with actual results of tests.  Thanks to
	Arjen Markus.  => tcltest 2.1 [Patch 521362]

2002-06-03  Miguel Sofer  <msofer@users.sourceforge.net>

	* doc/namespace.n: added description of [namepace forget]
	behaviour for unqualified patterns [Bug 559268]

2002-06-03  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: reverting an accidental modification in
	the last commit.
	
2002-06-03  Miguel Sofer  <msofer@users.sourceforge.net>

	* doc/Tcl.n: clarify the empty variable name issue ([Bug 549285]
	reported by Tom Krehbiel, patch by Don Porter).

2002-05-31  Don Porter  <dgp@users.sourceforge.net>

	* library/package.tcl:  Fixed leak of slave interp in [pkg_mkIndex].
	Thanks to Helmut for report.  [Bug 550534]

	* tests/io.test:
	* tests/main.test:  Use the "stdio" constraint to control whether
	an [open "|[interpreter]"] is attempted.

	* generic/tclExecute.c (TclMathInProgress,TclExecuteByteCode
		ExprCallMathFunc):
	* generic/tclInt.h (TclMathInProgress):
	* unix/Makefile.in (tclMtherr.*):
	* unix/configure.in (NEED_MATHERR):
	* unix/tclAppInit.c (matherr):
	* unix/tclMtherr.c (removed file):
	* win/tclWinMtherr.c (_matherr): Removed internal routine
	TclMathInProgress and Unix implementation of matherr().  These
	are now obsolete, dealing with very old versions of the C math
	library.  Windows version is retained in case Borland compilers
	require it, but it is inactive.  Thanks to Joe English.
	[Bug 474335, Patch 555635].
	* unix/configure: regen

2002-05-30  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompExpr.c:
	* generic/tclCompile.c:
	* generic/tclCompile.h: removed exprIsJustVarRef and
	exprIsComparison from the ExprInfo and CompileEnv structs. These
	were set, but not used since dec 1999 [Bug 562383].

2002-05-30  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c (TclGlob): fix to longstanding
	'knownBug' in fileName tests 15.2-15.4, and fix to a new
	Tcl 8.4 bug in certain uses of 'glob -tails'.
	* tests/fileName.test: removed 'knownBug' flag from some tests,
	added some new tests for above bugs.
	
2002-05-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/configure: regen'ed
	* unix/configure.in: replaced bigendian check with autoconf
	standard AC_C_BIG_ENDIAN, which defined WORDS_BIGENDIAN on
	bigendian systems.
	* generic/tclUtf.c (Tcl_UniCharNcmp): 
	* generic/tclInt.h (TclUniCharNcmp): use WORDS_BIGENDIAN instead of
	TCL_OPTIMIZE_UNICODE_COMPARE to enable memcmp alternative.

	* generic/tclExecute.c (TclExecuteByteCode INST_STR_CMP):
	* generic/tclCmdMZ.c (Tcl_StringObjCmd): changed the case for
	choosing the Tcl_UniCharNcmp compare to when both objs are of
	StringType, as benchmarks show that is the optimal check (both
	bigendian and littleendian systems).

2002-05-29  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclMain.c: Removed "dummy" reference to Tcl_LinkVar.
	It is no longer needed since Tcl_Main() now actually calls
	Tcl_LinkVar().  Thanks to Joe English for pointing that out.

2002-05-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): 
	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Use the macro version.
	* generic/tclInt.h (TclUniCharNcmp): Optimised still further with
	a macro for use in sensitive places like tclExecute.c

	* generic/tclUtf.c (Tcl_UniCharNcmp): Use new flag to figure out
	when we can use an optimal comparison scheme, and default to the
	old scheme in other cases which is at least safe.
	* unix/configure.in (TCL_OPTIMIZE_UNICODE_COMPARE): New optional
	flag that indicates when we can use memcmp() to compare Unicode
	strings (i.e. when the high-byte of a Tcl_UniChar precedes the
	low-byte.)

2002-05-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclInt.decls:
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c:
	* generic/tclUtf.c: added TclpUtfNcmp2 private command that
	mirrors Tcl_UtfNcmp, but takes n in bytes, not utf-8 chars.  This
	provides a faster alternative for comparing utf strings	internally.
	(Tcl_UniCharNcmp, Tcl_UniCharNcasecmp): removed the explicit end
	of string check as it wasn't correct for the function (by doc and
	logic).

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): reworked the string equal
	comparison code to use TclpUtfNcmp2 as well as short-circuit for
	equal objects or unequal length strings in the equal case.
	Removed the use of goto and streamlined the other parts.

	* generic/tclExecute.c (TclExecuteByteCode): added check for
	object equality in the comparison instructions.  Added
	short-circuit for != length strings in INST_EQ, INST_NEQ and
	INST_STR_CMP.  Reworked INST_STR_CMP to use TclpUtfNcmp2 where
	appropriate, and only use Tcl_UniCharNcmp when at least one of the
	objects is a Unicode obj with no utf bytes.

	* generic/tclCompCmds.c (TclCompileStringCmd): removed error
	creation in code that no longer throws an error.

	* tests/string.test:
	* tests/stringComp.test: added more string comparison checks.

	* tests/clock.test: better qualified 9.1 constraint check for %s.

2002-05-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclThreadAlloc.c (TclpRealloc, TclpFree): protect
	against the case when NULL is based.

	* tests/clock.test: added clock-9.1
	* compat/strftime.c:
	* generic/tclClock.c:
	* generic/tclInt.decls:
	* generic/tclIntDecls.h:
	* unix/tclUnixTime.c: fix for Windows msvcrt mem leak caused by
	using an env(TZ) setting trick for in clock format -gmt 1.  This
	also makes %s seem to work correctly with -gmt 1 as well as
	making it a lot faster by avoid the env(TZ) hack.  TclpStrftime
	now takes useGMT as an arg.  [Bug #559376]

2002-05-28  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclIOUtil.c: fixes to Tcl_FSLoadFile when called on
	a file inside a vfs.  This should avoid leaving temporary 
	files sitting around on exit. [Bug #545579]
	
2002-05-27  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* win/tclWinError.c: Added comment on conversion of
	ERROR_NEGATIVE_SEEK because that is a mapping that really belongs,
	and not a catch-all case.
	* win/tclWinPort.h (EOVERFLOW): Should be either EFBIG or EINVAL
	* generic/tclPosixStr.c (Tcl_ErrnoId, Tcl_ErrnoMsg): EOVERFLOW can
	potentially be a synonym for EINVAL.

2002-05-24  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	=== Changes due to TIP#91 ===

	* win/tclWinPort.h: Added declaration of EOVERFLOW.
	* doc/CrtChannel.3: Added documentation of wideSeekProc.
	* generic/tclIOGT.c (TransformSeekProc, TransformWideSeekProc):
	Adapted to use the new channel mechanism.
	* unix/tclUnixChan.c (FileSeekProc, FileWideSeekProc): Renamed
	FileSeekProc to FileWideSeekProc and created new FileSeekProc
	which has the old-style interface and which errors out with
	EOVERFLOW when the returned file position can't fit into the
	return type (int for historical reasons.)
	* win/tclWinChan.c (FileSeekProc, FileWideSeekProc): Renamed
	FileSeekProc to FileWideSeekProc and created new FileSeekProc
	which has the old-style interface and which errors out with
	EOVERFLOW when the returned file position can't fit into the
	return type (int for historical reasons.)
	* mac/tclMacChan.c (FileSeek): Reverted to old interface; Macs
	lack large-file support because I can't see how to add it.
	* generic/tclIO.c (Tcl_Seek, Tcl_Tell): Given these functions
	knowledge of the new arrangement of channel types.
	(Tcl_ChannelVersion): Added recognition of new version code.
	(HaveVersion): New function to do version checking.
	(Tcl_ChannelBlockModeProc, Tcl_ChannelFlushProc)
	(Tcl_ChannelHandlerProc): Made these functions use HaveVersion for
	ease of future maintainability.
	(Tcl_ChannelBlockModeProc): Obvious lookup function.
	* generic/tcl.h (Tcl_ChannelType): New wideSeekProc field, and
	seekProc type restored to old interpretation.
	(TCL_CHANNEL_VERSION_3): New channel version.

2002-05-24  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
	
	* tests/winPipe.test: Applied patch for SF Tcl Bug #549617. Patch
	  and bug report by Kevin Kenny <kennykb@users.sourceforge.net>.

	* win/tclWinSock.c (TcpWatchProc): Fixed SF Tcl Bug #557878. We
	  are not allowed to mess with the watch mask if the socket is a
	  server socket. I believe that the original reporter is George
	  Peter Staplin.

2002-05-21  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/configure.in: Invoke SC_ENABLE_SHARED before
	calling SC_CONFIG_CFLAGS so that the SHARED_BUILD
	variable can be checked inside SC_CONFIG_CFLAGS.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Pass -non_shared
	instead of -shared to ld when configured with
	--disable-shared under OSF. [Tcl bug 540390]

2002-05-20  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclInt.h: added prototype for TclpFilesystemPathType().
	* mac/tclMacChan.c: use MSL provided creator type if available
	instead of the default 'MPW '.

2002-05-16  Joe English  <jenglish@users.sf.net>

	* doc/CrtObjCmd.3: 
	Added Tcl_GetCommandFromObj, Tcl_GetCommandFullName
	(Tcl Bug #547987, #414921)

2002-05-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* unix/tclUnixChan.c (TtyOutputProc): #if/#endif-ed this function
	out to stop compiler warnings.  Also much general tidying of
	comments in this file and removal of whitespace from blank lines.

2002-05-13  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* unix/tclUnixChan.c (SETBREAK): Solaris thinks ioctl() takes a
	signed second argument, and Linux thinks ioctl() takes an unsigned
	second argument.  So need a longer definition of this macro to get
	neither to spew warnings...

2002-05-13  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclEvent.c: 
	* generic/tclIOUtil.c:
	* generic/tclInt.h: clean up all memory allocated by the
	filesystem, via introduction of 'TclFinalizeFilesystem'.
	Move TclFinalizeLoad into TclFinalizeFilesystem so we can
	be sure it is called at just the right time.
	Fix bad comment also.  [Bug #555078 and 'fs' part of #543549]
	* win/tclWinChan.c: fix comment referring to wrong function.
	
2002-05-10  Don Porter  <dgp@users.sourceforge.net>

	* tests/load.test:
	* tests/safe.test:
	* tests/tcltest.test: Corrected some list-quoting issues and
	other matters that cause tests to fail when the patch includes
	special characters.  Report from Vince Darley.  [Bug 554068].

2002-05-08    David Gravereaux <davygrvy@pobox.com>

	* doc/file.n:
	* tools/man2tcl.c:
	* tools/man2help2.tcl:  Thanks to Peter Spjuth
	<peter.spjuth@space.se>, again.  My prior fix for
	single-quote macro mis-understanding was wrong.	 Reverted to
	reimpliment the 'macro2' proc which handles single-quote macros
	and restored file.n text arrangement to avoid single-quotes on
	the first line.  Sorry for all the confusion.

2002-05-08  David Gravereaux <davygrvy@pobox.com>

	* tools/man2tcl.c:
	* tools/man2help2.tcl: Proper source of macro error mis-
	understanding single-quote as the leading macro command found
	and repaired.

	* doc/file.n: Reverted to prior state before I messed with
	it.

2002-05-08  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl: Corrected [uplevel] quoting when
	[source]-ing test script in subdirectories.
	* tests/fileName.test:
	* tests/load.test:
	* tests/main.test:
	* tests/tcltest.test: 
	* tests/unixInit.test: Fixes to test suite when there's a space
	in the working path.  Thanks to Kevin Kenny.

2002-05-07  David Gravereaux <davygrvy@pobox.com>

	-- Changes from Peter Spjuth <peter.spjuth@space.se>
	* tools/man2tcl.c: Increased line buffer size and a bail-out if
	that should ever be over-run.
	* tools/man2help.tcl: Include Courier New font in rtf header.
	* tools/man2help2.tcl: Improved handling of CS/CE fields.  Use
	Courier New for code samples and indent better.

	* doc/file.n:
	* doc/TraceCmd.3:  winhelp conversion tools where understanding
	a ' as the first character on a line to be an unknown macro.
	Not knowing how to repair tools/man2tcl.c, I decided to rearrange
	the text in the docs instead.

2002-05-07  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c: fix to similar segfault when using 
	'glob -types nonsense -dir dirname -join * *'. [Bug 553320]
	
	* doc/FileSystem.3: further documentation on vfs.
	* tests/cmdAH.test:
	* tests/fileSystem.test:
	* tests/pkgMkindex.test: Fix to testsuite bugs when running out
	of directory whose name contains '{' or '['.

2002-05-07  Miguel Sofer  <msofer@users.sourceforge.net>

	* tests/basic.test: Fix for [Bug 549607]
	* tests/encoding.test: Fix for [Bug 549610]
	These are testsuite bugs that caused failures when the filename
	contained spaces. Report & fix by Kevin Kenny.

2002-05-02  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c: fix to freeing a bad object 
	(i.e. segfault) when using 'glob -types nonsense -dir dirname'.
	* generic/tclWinFile.c: fix to [Bug 551306], also wrapped some 
	long lines.
	* tests/fileName.test: added several tests for the above bugs.
	* doc/FileSystem.3: clarified documentation on refCount
	requirements of the object returned by the path type function.
	* generic/tclIOUtil.c:
	* win/tclWinFile.c:
	* unix/tclUnixFile.c:
	* mac/tclMacFile.c: moved TclpFilesystemPathType to the
	platform specific directories, so we can add missing platform-
	specific implementations.  On Windows, 'file system' now returns 
	useful results like "native NTFS", "native FAT" for that system.  
	Unix and MacOS still only return "native".
	* doc/file.n: clarified documentation.
	* tests/winFile.test: test for 'file system' returning correct
	values.
	* tests/fileSystem.test: test for 'file system' returning correct
	values.  Clean up after failed previous test run.
	
2002-04-26  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/configure:
	* unix/tcl.m4: change HP-11 SHLIB_LD_LIBS from "" to ${LIBS} so
	that the .sl knows its dependent libs.

2002-04-26  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/obj.test (obj-11.[56]): Test conversion to boolean more
	thoroughly.
	* generic/tclObj.c (SetBooleanFromAny): Was not calling an integer
	parsing function on native 64-bit platforms!  [Bug 548686]

2002-04-24  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclInt.h: corrected TclRememberJoinableThread decl to
	use VOID instead of void.
	* generic/tclThreadJoin.c: noted that this code isn't needed on Unix.

2002-04-23  Jeff Hobbs  <jeffh@ActiveState.com>

	* doc/exec.n: 
	* doc/tclvars.n: doc updates [Patch #509426] (gravereaux)

2002-04-24  Daniel Steffen  <das@users.sourceforge.net>

	* mac/tclMacResource.r: added check of
	TCLTK_NO_LIBRARY_TEXT_RESOURCES #define to allow disabling the
	inclusion of the tcl library code in the resource fork of Tcl
	executables and shared libraries.

2002-04-23  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/TraceCmd.3: New file that documents Tcl_CommandTraceInfo,
	Tcl_TraceCommand and Tcl_UntraceCommand [Bug 414927]

2002-04-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclAlloc.c:
	* generic/tclInt.h:
	* generic/tclThreadAlloc.c (new):
	* unix/Makefile.in:
	* unix/tclUnixThrd.c:
	* win/Makefile.in:
	* win/tclWinInt.h:
	* win/tclWinThrd.c: added new threaded allocator contributed by
	AOL that significantly reduces lock contention when multiple
	threads are in use.  Only Windows and Unix implementations are
	ready, and the Windows one may need work.  It is only used by
	default on Unix for now, and requires that USE_THREAD_ALLOC be
	defined (--enable-threads on Unix will define this).

	* generic/tclIOUtil.c (Tcl_FSRegister, Tcl_FSUnregister):
	corrected calling of Tcl_ConditionWait to ensure that there would
	be a condition to wait upon.

	* generic/tclCmdAH.c (Tcl_FileObjCmd): added cast in FILE_SIZE.

	* win/tclWinFCmd.c (DoDeleteFile): check return of setattr API
	calls in file deletion for correct Win32 API handling.

	* win/Makefile.in: correct dependencies for shell, gdb, runtest
	targets.

	* doc/clock.n:
	* compat/strftime.c (_fmt): change strftime to correctly handle
	localized %c, %x and %X on Windows.  Added some notes about how
	the other values could be further localized.

2002-04-19  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclMain.c (Tcl_Main):  Free the memory allocated for the
	startup script path.  [Bug 543549]

	* library/msgcat/msgcat.tcl:  [mcmax] wasn't using the caller's
	namespace when determining the max translated length.  Also
	made revisions for better use of namespace variables and more
	efficient [uplevel]s.

	* doc/msgcat.n:
	* library/msgcat/msgcat.tcl:
	* library/msgcat/pkgIndex.tcl:  Added [mcload] to the export list
	of msgcat; bumped to 1.2.3.  [Bug 544727]

2002-04-20  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclInt.decls:
	* generic/tclIntPlatDecls.h:
	* generic/tclStubInit.c:
	* mac/tclMacFCmd.c:
	* mac/tclMacFile.c:
	* mac/tclMacUtil.c: Modified TclpObjNormalizePath to be alias
	file aware, and replaced various calls to FSpLocationFrom*Path
	by calls to new alias file aware versions FSpLLocationFrom*Path.
	The alias file aware routines don't resolve the last component of
	a path if it is an alias. This allows [file copy/delete] etc. to
	act correctly on alias files. (c.f. discussion in Bug #511666)

2002-04-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/lindex.test (lindex-3.7): 
	* generic/tclUtil.c (TclGetIntForIndex): Stopped indexes from
	hitting wide ints.  [Bug #526717]

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

	* generic/tclNamesp.c:
	* tests/info.test: [Bug 545325] info level didn't report
	namespace eval, bug report by Richard Suchenwirth.

2002-04-18  Don Porter  <dgp@users.sourceforge.net>

	* doc/subst.n:  Clarified documentation on handling unusual return
	codes during substitution, and on variable substitutions implied
	by command substitution, and vice versa.  [Bug 536838]

2002-04-18  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclCmdIL.c (InfoBodyCmd): 
	* tests/info.test (info-2.6): Proc bodies without string reps
	would report as empty [Bug #545644]

	* generic/tclCmdMZ.c (Tcl_SubstObj): More clarification for
	comment on behaviour when substitutions are not well-formed,
	prompted by [Bug #536831]; alas, removing the ill-defined
	behaviour is a lot of work.

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

	* generic/tclExecute.c:
	* tests/expr-old.test: fix for [Bug #542588] (Phil Ehrens), where
	"too large integers" were reported as "floating-point value" in
	[expr] error messages.

2002-04-17  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclEncoding.c (EscapeFromUtfProc): 
	* generic/tclIO.c (WriteChars, Tcl_Close): corrected the handling
	of outputting end escapes for escape-based encodings.
	[Bug #526524] (yamamoto)

2002-04-17  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n:  Removed [saveState] and [restoreState] from
	tcltest 2 documentation, effectively deprecating them.  [Bug 495660]
	* library/tcltest/tcltest.tcl: Made separate export for commands
	kept only for tcltest 1 compatibility.

	* tests/iogt.test: Revised to run tests in a namespace, rather than
	use the useless and buggy [saveState] and [restoreState] commands
	of tcltest.  Updated to use tcltest 2 as well.  [Patch 544911]

2002-04-16  Don Porter  <dgp@users.sourceforge.net>

	* tests/io.test: Revised to run tests in a namespace, rather than
	use the useless and buggy [saveState] and [restoreState] commands
	of tcltest.  Updated to use tcltest 2 as well.  [Patch 544546]

2002-04-15  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclProc.c:
	* tests/proc-old.test: Improved stack trace for TCL_BREAK and
	TCL_CONTINUE returns from procs. Patch by Don Porter
	[Bug 536955]. 
	
	* generic/tclExecute.c:
	* tests/compile.test: made bytecodes check for a catch before
	  returning; the compiled [return] is otherwise non-catchable. 
	  [Bug 542142] reported by Andreas Kupries.

2002-04-15  Don Porter  <dgp@users.sourceforge.net>

	* tests/socket.test:  Increased timeout values so that tests have
	time to successfully complete even on slow/busy machines.  [Bug 523470]

	* doc/tcltest.n:
	* library/tcltest/tcltest.tcl:
	* tests/tcltest.test:  Revised [tcltest::test] to return errors
	when called with invalid syntax and to accept exactly two arguments
	as documented.  Improved error messages.  [Bug 497446, Patch 513983]
	***POTENTIAL INCOMPATIBILITY***: Incompatible with previous
	tcltest 2.* releases, found only in alpha releases of Tcl 8.4.

2002-04-11  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclNotify.c (TclFinalizeNotifier): remove remaining
	unserviced events on finalization.

	* win/tcl.m4: Enabled COFF as well as CV style debug info with
	--enable-symbols to allow Dr. Watson users to see function info.
	More info on debugging levels can be obtained at:
	http://msdn.microsoft.com/library/en-us/dnvc60/html/gendepdebug.asp

	* tests/ioCmd.test: fixed iocmd-8.15 to have mac and unixPc variants.

	* generic/tclParse.c (Tcl_ParseVar): conditionally incr obj
	refcount to prevent possible mem leak.

2002-04-08  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tcl.h: no <sys/types.h> on mac.
	* mac/tclMacFile.c: minor fixes to Vince's changes from 03-24.
	* mac/tclMacOSA.c:
	* mac/tclMacResource.c: added missing Tcl_UtfToExternalDString
	conversions of resource file names.
	* mac/tclMacSock.c (TcpGetOptionProc): fixed bug introduced
	by Andreas on 02-25; changed strcmp's to strncmp's so that
	option comparison behaves like on other platforms.
	* mac/tcltkMacBuildSupport.sea.hqx (CW Pro6 changes): added
	support to allow Tk to hookup C library stderr/stdout to TkConsole.
	* tests/basic.test:
	* tests/cmdAH.test:
	* tests/encoding.test:
	* tests/fileSystem.test:
	* tests/ioCmd.test: fixed tests failing on mac: check for 
	existence of [exec], changed some result strings.

2002-04-06  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixFCmd.c (Realpath): added a little extra code to
	initialize a realpath arg when compiling in PURIFY mode in order
	to prevent spurious purify warnings.  We should really create our
	own realpath implementation, but this will at least quiet purify
	for now.

2002-04-05  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c (Tcl_SubstObj):
	* tests/subst.test:  Corrected [subst] so that return codes
	TCL_BREAK and TCL_CONTINUE returned by variable substitution
	have the same effect as when those codes are returned by command
	substitution.  [Bug 536879]

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

	* library/tcltest/tcltest.tcl: added getMatchingFiles back (alias
	to GetMatchingFiles), which was a public function in tcltest 1.0.

2002-04-01  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclEnv.c:
	* generic/tclIOUtil.c: invalidate filesystem cache when the
	user changes env(HOME).  Fixes [Bug #535621].  Also cleaned up
	some of the documentation.
	* tests/fileSystem.test: added test for bug just fixed.
	
2002-04-01  Kevin Kenny  <kennykb@acm.org>

	* win/tclWinTime.c (Tcl_GetTime): made the checks of clock
	frequency more permissive to cope with the fact that Win98SE
	is observed to return 1.19318 in place of 1.193182 for the
	performance counter frequency.
	
2002-03-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCmdMZ.c (Tcl_TraceObjCmd, TraceVarProc)
	(TraceCommandProc, TclTraceCommandObjCmd):  corrected
	potential double-free of traces on variables by flagging in
	Trace*Proc that it will free the var in case the eval wants to
	delete the var trace as well. [Bug #536937]
	Also converted Tcl_UntraceVar -> Tcl_UntraceVar2 and Tcl_Eval to
	Tcl_EvalEx in Trace*Proc for slight efficiency improvement.

2002-03-29  Don Porter  <dgp@users.sourceforge.net>

	* doc/AllowExc.3:
	* generic/tclBasic.c (Tcl_EvalObjv,Tcl_EvalEx,Tcl_EvalObjEx):
	* generic/tclCompile.h (TclCompEvalObj):
	* generic/tclExecute.c (TclCompEvalObj,TclExecuteByteCode):
	* tests/basic.test: Corrected problems with Tcl_AllowExceptions
	having influence over the wrong scope of Tcl_*Eval* calls.  Patch
	from Miguel Sofer.  Report from Jean-Claude Wippler.  [Bug 219181]

2002-03-28  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclVar.c: Refactored CallTraces to collect repeated
	handling of its returned value into CallTraces itself.

2002-03-28  David Gravereaux <davygrvy@pobox.com>

	* tools/feather.bmp:
	* tools/man2help.tcl:
	* tools/man2help2.tcl:
	* win/makefile.vc: More winhelp target fixups.  Added a feather
	bitmap to the non-scrollable area and changed the color to be
	yellow from a plain white.  The colors can be whatever we want
	them to be, but thought I would start with something bold.
	[Bug 527941]

	* doc/SetVar.3:
	* doc/TraceVar.3:
	* doc/UpVar.3:  .AP macro syntax repair.

2002-03-27  David Gravereaux <davygrvy@pobox.com>

	* tools/man2help.tcl:
	* win/makefile.vc:  winhelp target now copies all needed files
	from tools/ to a workarea under $(OUT_DIR) and builds it from
	there.  No build cruft is left in tools/ anymore.  All paths
	used in man2help.tcl are now relative to where the script is.
	[Bug 527941]

2002-03-27  David Gravereaux <davygrvy@pobox.com>

	* win/.cvsignore:
	* win/buildall.vc.bat:
	* win/coffbase.txt:
	* win/makefile.vc:
	* win/nmakehlp.c (new):
	* win/rules.vc:  First draft fix for [Bug 527941].  More changes
	need to done to the makehelp target to get to stop leaving build
	files in the tools/ directory.  This does not address the syntax
	errors in the man files.  Having the contents of tcl.hpj(.in)
	inside makefile.vc allows for version numbers to be replaced with
	macros.
	
	The new nmakehlp.c is built by rules.vc in preprocessing and removes
	the need to use tricky shell syntax that wasn't compatible on Win9x
	systems.  Clean targets made Win9x complient.  This is a first draft
	repair for [Bug 533862].

2002-03-28  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_EvalEx): passing the correct commandSize
	to TclEvalObjvInternal. [Bug 219362], fix by David Knoll.

2002-03-28  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_EvalEx):
	* tests/basic.test: avoid exceptional returns at level 0 
	[Bug 219181] 

2002-03-27  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n ([mainThread]):
	* library/tcltest/tcltest.tcl:
	* tests/tcltest.test:  Major code cleanup to deal with whitespace,
	coding conventions, and namespace issues, with several minor bugs
	fixed in the process.

	* tests/main.test: Added missing [after cancel]s.

2002-03-25  Don Porter  <dgp@users.sourceforge.net>

	* tests/main.test: Removed workarounds for Bug 495977.

	* library/tcltest/tcltest.tcl:  Keep the value of $::auto_path
	unchanged, so that the tcltest package can test code that depends
	on auto-loading.  If a testing application needs $::auto_path pruned,
	it should do that itself.  [Bug 495726]
	Improve the processing of the -constraints option to [test] so that
	constraint lists can have arbitrary whitespace, and non-lists don't
	blow things up.  [Bug 495977]
	Corrected faulty variable initialization. [Bug 534845]

2002-03-25  Miguel Sofer  <msofer@users.sourceforge.net>

	* doc/CrtTrace.3: small doc correction
	* generic/tclBasic.c (Tcl_DeleteTrace): Allow NULL callback on
	trace deletions [Bug 534728] (Hemang Lavana).

2002-03-24  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_EvalObjv): replaced obscure, incorrect
	code as described in [Bug 533907] (Don Porter).

2002-03-24  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:  Use [interpreter] to set/query the
	executable currently running the tcltest package.  [Bug 454050]

	* library/tcltest/tcltest.tcl:  Allow non-proc commands to be used
	as the customization hooks.  [Bug 495662]

	* doc/file.n:
	* tests/cmdAH.test:
	* tests/fileName.test:
	* tests/fileSystem.test: (new file)	
	* tests/winFCmd.test: fix [Bug 511666] and [Bug 511658],
	and improved documentation of some aspects of the filesystem,
	particularly 'Tcl_FSMatchInDirectory' which now might match
	a single file/directory only, and 'file normalize' which
	wasn't very clear before.  Removed inconsistency betweens
	docs and the Tcl_Filesystem structure.  Also fixed 
	[Bug 523217] and corrected file normalization on Unix so that 
	it expands symbolic links.  Added some new tests of the 
	filesystem code (in the new file 'fileSystem.test'), and 
	some extra tests for correct handling of symbolic links.
	Fix to [Bug 530960] which shows up on Win98.  Made comparison
	with ".com" case insensitive in tclWinPipe.c
	
	***POTENTIAL INCOMPATIBILITY***: But only between alpha
	releases (users of the new Tcl_Filesystem lookup table in Tcl
	8.4a4 need to handle the new way in which Tcl may call
	Tcl_FSMatchInDirectory, and 'file normalize' on unix now
	behaves correctly).  Only known impact is with the 'tclvfs'
	extension.

2002-03-22  Miguel Sofer  <msofer@users.sourceforge.net>

	* tests/basic.test (basic-46.1): adding test for [Bug 533758],
	fixed earlier today.
	
2002-03-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinInt.h: moved undef of TCL_STORAGE_CLASS. [Bug #478579]

2002-03-22  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_EvalObjEx):
	* generic/tclExecute.c (TclCompEvalObj): fixed the errorInfo for
	return codes other than (TCL_OK, TCL_ERROR) to runLevel 0 
	[Bug 533758]. Removed the static RecordTracebackInfo(), as its
	functionality is easily replicated by Tcl_LogCommandInfo. Bug
	and redundancy noted by Don Porter.

2002-03-21  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/expr.n: Improved documentation for ceil and floor [Bug 530535]

	DoCopyFile, _except_docopyfile_handler):
	Implement SEH support under gcc using inline asm.
	Tcl and Tk should now compile with Mingw 1.1. [Patch 525746]

2002-03-14  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWinFCmd.c (DoRenameFile, DoCopyFile): Handle
	an SEH exception with EXCEPTION_EXECUTE_HANDLER instead
	of restarting the faulting instruction with
	EXCEPTION_CONTINUE_EXECUTION. Bug 466102 provides an
	example of how restarting could send Tcl into an
	infinite loop. [Patch 525746]

2002-03-11  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWinFCmd.c (DoRenameFile, DoCopyFile, DoDeleteFile,
	DoRemoveJustDirectory): Make sure we don't pass NULL or ""
	as a path name to Win32 API functions since this was
	crashing under Windows 98.

2002-03-11  Don Porter  <dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl (getMatchingFiles): Pass
	a proper list to foreach to avoid munging a Windows
	patch like D:\Foo\Bar into D:FooBar before the glob.

2002-03-11  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclEncoding.c: Fix typo in comment.
	* generic/tclIO.c (DoReadChars, ReadBytes, ReadChars):
	Use NULL value instead of pointer set to NULL to make
	things more clear. Reorder arguments so that they
	match the function signatures. Cleanup little typos
	and add more descriptive comment.

2002-03-08  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/README: Update to indicate that Mingw 1.1 is
	required to build Tcl. Add section describing new
	msys based build process. Update Cygwin build
	instructions so users know where to find Mingw 1.1.

2002-03-08  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinFCmd.c (DoCopyFile): correctly set retval to TCL_OK.

2002-03-07  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWin32Dll.c (TclpCheckStackSpace):
	* win/tclWinFCmd.c (DoRenameFile, DoCopyFile): Replace
	hard coded constants with Win32 symbolic names.
	Move control flow statements out of __try blocks
	since the documentation indicates it is frowned upon.

2002-03-07  Don Porter  <dgp@users.sourceforge.net>

	* doc/interp.n:
	* generic/tclInterp.c(Tcl_InterpObjCmd,SlaveObjCmd,SlaveRecursionLimit):
	* generic/tclTest.c:
	* tests/interp.test: Added the [interp recursionlimit] command to
	set/query the recursion limit of an interpreter.  Proposal and
	implementation from Stephen Trier. [TIP 87, Patch 522849]

2002-03-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tcl.h, tools/tcl.wse.in, unix/configure.in,
	* unix/tcl.spec, win/README.binary, win/configure.in, README:
	Bumped patchlevel; this might need to change in the future, but it
	will help us distinguish between the CVS version and the most
	recent released version.

2002-03-06  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclInt.h: for unshared objects, TclDecrRefCount now
	frees the internal rep before the string rep - just like the
	non-macro Tcl_DecrRefCount/TclFreeObj [Bug 524802]. 

2002-03-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/lsearch.n: Documentation of new features, plus examples.
	* tests/lsearch.test: Tests of new features.
	* generic/tclCmdIL.c (Tcl_LsearchObjCmd): TIP#80 support.  See
	http://purl.org/tcl/tip/80 for details.

2002-03-05  Jeff Hobbs  <jeffh@ActiveState.com>

	*** 8.4a4 TAGGED FOR RELEASE ***

	* unix/tclUnixChan.c: initial remedy for [Bug #525783] flush
	problem introduced by TIP #35.  This may not satisfy true serial
	channels, but it restores the correct flushing of std* channels on
	exit.

	* unix/README: added --enable-langinfo doc.

	* unix/tcl.spec:
	* tools/tcl.wse.in: fixed URL refs to use www.tcl.tk or SF.

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

	* README:
	* mac/README:
	* unix/Makefile.in:
	* unix/README:
	* win/README:
	* win/README.binary: updated to use www.tcl.tk URL.

	* unix/Makefile.in: added older ChangeLogs to dist target.

	* tests/io.test:
	* tests/encoding.test: corrected iso2022 encoding results.
	added encoding-24.*
	* generic/tclEncoding.c (EscapeFromUtfProc): corrected output of
	escape codes as per RFC 1468. [Patch #474358] (taguchi)
	(TclFinalizeEncodingSubsystem): corrected potential double-free
	when encodings were finalized on exit. [Bug #219314, #524674]

2002-03-01  Jeff Hobbs  <jeffh@ActiveState.com>

	* library/encoding/iso2022-jp.enc: 
	* library/encoding/iso2022.enc: 
	* tools/encoding/iso2022-jp.esc:
	* tools/encoding/iso2022.esc: gave <ESC>$B precedence over <ESC>$@,
	based on comments (point 1) in [Bug #219283] (rfc 1468)

	* tests/encoding.test: added encoding-23.* tests
	* generic/tclIO.c (FilterInputBytes): reset the TCL_ENCODING_START
	flags in the ChannelState when using 'gets'. [Bug #523988]
	Also reduced the value of ENCODING_LINESIZE from 30 to 20 as this
	seems to improve the performance of 'gets' according to tclbench.

2002-02-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCmdMZ.c (TraceCommandProc): ensure that TraceCommandInfo
	structure was also deleted when a command was deleted to prevent a
	mem leak.

	* generic/tclBasic.c (Tcl_CreateObjTrace): set tracePtr->flags
	correctly.

	* generic/tclTimer.c (TimerExitProc): remove remaining events in
	tls on thread exit.

2002-02-28  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclNamesp.c: allow cached fully-qualified namespace
	names to be usable from different namespaces within the same
	interpreter without forcing a new lookup [Patch 458872]. 

2002-02-28  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: Replaced a few direct stack accesses 
	with the POP_OBJECT() macro [Bug 507181] (Don Porter).

2002-02-27  Don Porter  <dgp@users.sourceforge.net>

	* doc/GetIndex.3:
	* generic/tcl.decls (Tcl_GetIndexFromObjStruct):
	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct):  Revised the
	prototype of the Tcl_GetIndexFromObjStruct to take its struct
	table as a (CONST VOID *) argument, better describing what it is,
	maintaining source compatibility, and adding CONST correctness
	according to TIP 27.  Thanks to Joe English for an elegant
	solution. [Bug 520304]

	* generic/tclDecls.h: make genstubs

	* generic/tclMain.c (Tcl_Main,StdinProc):  Corrected some reference
	count management errors on the interactive command Tcl_Obj found by
	Purify.  Thanks to Jeff Hobbs for the report and assistance.

2002-02-27  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclBasic.c (Tcl_EvalTokensStandard): corrected mem leak
	in error case.

	* generic/tclTest.c (TestStatProc[123]): correct harmless UMRs.

	* generic/tclLink.c (Tcl_LinkVar): correct mem leak in error case.

2002-02-27  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* tests/socket.test (2.7): Accepted and applied patch for Tcl SF
	  bug #523470 provided by Don Porter <dgp@users.sourceforge.net>
	  to avoid timing problems in that test.

	* unix/tclUnixChan.c (TclpOpenFileChannel): Added code to regonize
	  "/dev/tty" (by name) and to not handle it as tty / serial
	  line. This is the controlling terminal and is special. Setting
	  it into raw mode as is done for other tty's is a bad idea. This
	  is a hackish fix for expect SGF Bug #520624. The fix has
	  limitation: Tcl_MakeFileChannel handles tty's specially too, but
	  is unable to recognize /dev/tty as it only gets a file
	  descriptor, and no name for it.

2002-02-26  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCmdAH.c (StoreStatData): corrected mem leak.

	* generic/tclCmdMZ.c (Tcl_RegsubObjCmd): prevent obj leak in
	  remedial regsub case.

	* generic/tclFileName.c (Tcl_TranslateFileName): decr refcount for
	  error case to prevent mem leak.

	* generic/tclVar.c (Tcl_ArrayObjCmd): removed extra obj allocation.

	* unix/tclUnixSock.c (Tcl_GetHostName): added an extra
	  gethostbyname check to guard against failure with truncated
	  names returned by uname.

	* unix/configure:
	* unix/tcl.m4 (SC_SERIAL_PORT): added sys/modem.h check and defined
	  _XOPEN_SOURCE_EXTENDED for HP-11 to get updated header decls.

	* unix/tclUnixChan.c: added Unix implementation of TIP #35, serial
	  port support. [Patch #438509] (schroedter)

2002-02-26  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCmpCmds.c: (bugfix to the bugfix, hopefully the last)
	  Bugfix to the new [for] compiling code: was setting a
	  exceptArray parameter using another param which wasn't yet
	  initialised, thus filling it with noise.

2002-02-25  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* mac/tclMacSock.c (TcpGetOptionProc): Changed to recognize the
	  option "-error". Essentially ignores the option, always
	  returning an empty string.

2002-02-25  Jeff Hobbs  <jeffh@ActiveState.com>

	* doc/Alloc.3:
	* doc/LinkVar.3:
	* doc/ObjectType.3:
	* doc/PkgRequire.3:
	* doc/Preserve.3:
	* doc/TCL_MEM_DEBUG.3: Updated documentation to describe the ckalloc,
	ckfree, ckrealloc, attemptckalloc, and attemptckrealloc macros, and
	to accurately describe when and how they are used. [Bug #497459] (dgp)

	* generic/tclHash.c (AllocArrayEntry, AllocStringEntry):
	Before invoking ckalloc when creating a Tcl_HashEntry,
	check that the amount of memory being allocated is
	at least as large as sizeof(Tcl_HashEntry). The previous
	code was allocating memory regions that were one
	or two bytes short. [Bug #521950] (dejong)

2002-02-25  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_EvalEx): avoiding a buffer overrun
	reported by Joe English, and restoring tcl7.6 behaviour for
	[subst]: badly terminated nested scripts will raise an error
	and not be evaluated. [Bug #495207]

2002-02-25  Don Porter  <dgp@users.sourceforge.net>

	* unix/tclUnixPort.h: corrected strtoll prototype mismatch on Tru64.
	* compat/strtod.c (strtod): simplified #includes
	* compat/strtol.c (strtol): gather result in a long before returning
	as a long: necessary on platforms where sizeof(int) != sizeof(long).

2002-02-25  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclLoadDyld.c: updated to use Mac OS X 10.1 dyld APIs that
	have more libdl-like semantics. (bug #514392)

2002-02-25  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompCmds: fixing a bug in patch dated 2002-02-22, in
	the code for [for] and [while]. Under certain conditions, for long
	bodies, the exception range parameters were badly computed. Tests
	forthcoming: I still can't reproduce the conditions in the
	testsuite (!), although the bug (with assorted segfault or panic!)
	can be triggered from the console or with the new parse.bench in  
	tclbench.
	
2002-02-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* compat/strtoul.c, compat/strtol.c, compat/strtod.c: Added UCHAR,
	CONST and #includes to clean up GCC output.

2002-02-23  Don Porter  <dgp@users.sourceforge.net>

	* compat/strtoull.c (strtoull):
	* compat/strtoll.c (strtoll):
	* compat/strtoul.c (strtoul): Fixed failure to handle leading
	sign symbols '+' and '-' and '0X' and raise overflow errors.
	[Bug 440916]  Also corrects prototype and errno problems.

2002-02-23  Mo DeJong  <mdejong@users.sourceforge.net>

	* configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Link with -n32
	instead of -32 when building on IRIX64-6.* system.
	[Tcl bug 521707]

2002-02-22  Don Porter <dgp@users.sourceforge.net>

	* generic/tclInt.h:
	* generic/tclObj.c: renamed global variable emptyString ->
	tclEmptyString because it is no longer static.
	* generic/tclPkg.c: Fix for panic when library is loaded on a
	platform without backlinking without proper use of stubs. [Bug 476537]

2002-02-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/regexpComp.test: updated regexp-11.[1-4] to match changes
	in regexp.test for new regsub syntax

	* unix/configure:
	* unix/tcl.m4: added --enable-64bit support for AIX-4 (using -q64
	flag) when using IBM's xlc compiler.

	* tests/safe.test: updated safe-8.5 and safe-8.7
	* library/safe.tcl (CheckFileName): removed the limit on
	sourceable file names (was only *.tcl or tclIndex files with no
	more than one dot and 14 chars).  There is enough internal
	protection in a safe interpreter already.  Fixes [Tk Bug #521560].

2002-02-22  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompCmds: [FR 465811]. Optimising [if], [for] and
	[while] for constant conditions; in addition, [for] and [while]
	are now compiled with the "loop rotation" optimisation (thanks to
	Kevin Kenny). 

2002-02-22  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	--- TIP#76 CHANGES ---
	* generic/tclCmdMZ.c (Tcl_RegsubObjCmd): Final-argument-less
	[regsub] returns the modified string.
	* doc/regsub.n: Updated docs.
	* tests/regexp.test: Updated and added tests.

	* compat/strtoll.c (strtoll): 
	* compat/strtoull.c (strtoull): 
	* unix/tclUnixPort.h:
	* win/tclWinPort.h: Const-ing 64-bit compatability declarations.
	Note that the return pointer is non-const because it is entirely
	legal for the functions to be called from somewhere that owns the
	string being passed.  Fixes problem reported by Larry Virden.

2002-02-21  David Gravereaux <davygrvy@pobox.com>

	* win/mkd.bat (removed):
	* win/coffbase.txt (new):
	* win/makefile.bc:
	* win/makefile.vc:  Changed the 'setup' target to stop using
	the mkd.bat file and just make the directory right in the rule.
	Same change to makefile.bc.  configure.in nor Makefile.in use
	it.

	coffbase.txt will be the master list for our "prefered base
	addresses" set by the linker.  This should improve load-time
	(NT only) by avoiding relocations.  Submissions to the list
	by extension authors are encouraged.

	Added a 'tidy' target to compliment 'clean' and 'hose' to remove
	just the outputs. Also removed the $(winlibs) macro as it wasn't
	being used.

	Stuff left to do:
	1) get the winhelp target to stop building in the tools/
	directory.
	2) stop using rmd.bat
	3) add more dependacy rules.

	* win/tclAppInit.c:  Reverted back to -r1.6, as the header file
	change to tclPort.h won't allow for easy embedded support
	outside of the source dist.  Thanks to Don Porter for pointing
	this out to me.

2002-02-21  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc:
	* win/rules.vc:  Added a new "loimpact" option that sets the
	-ws:aggressive linker option.  Off by default.  It's said to
	keep the heap use low at the expense of alloc speed.

	* win/tclAppInit.c: Changed #include "tcl.h" to be tclPort.h to
	remove the raw windows.h include.  tclPort.h brings in windows.h
	already and lessens the pre-compiled-header mush and the randomly
	useless	#pragma comment (lib,...) references throughout the big
	windows.h tree (as observed at high linker warning levels).

2002-02-21  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tcl.h: Better guessing of LP64/ILP32 architecture, but
	now sensitive to presence of (suitable) <limits.h>

2002-02-20  Don Porter <dgp@users.sourceforge.net>

	* generic/tcl.decls (Tcl_RegExpRange,Tcl_GetIndexFromObjStruct):
	Overlooked a few source incompatibilities.  Now using CONST84.
	* generic/tclDecls.h: make genstubs
	* generic/tcl.h (Tcl_CmdObjTraceProc): silence warning from Sun
	Workshop compiler.

2002-02-20  David Gravereaux <davygrvy@pobox.com>

	* win/buildall.vc.bat:
	* win/makefile.vc:
	* win/rules.vc: General clean-ups.  Added compiler and linker tests
	for a) the pentium 0x0F errata, b) optimizing (not all have this),
	and c) linker v6 section alignment confusion.  All these are tested
	first to make sure any D4002 or LNK1117 warnings aren't displayed.
	The pentium 0x0F errata is a recommended switch.  The v5 linker's
	section alignment default is 512, but the v6 linker was changed
	to 4096 in an attempt to speed loading on Win98.  I changed the
	default to always be 512 across both linkers, unless linking
	statically, then 4096 is used for the claimed speed effect. Using
	a 512 alignment saves 12k bytes of dead space in the DLL.

	Added IA64 B-stepping errata switch when the compiler supports it.

	Added profiling to $(lflags) when requested and also removed the
	explict -entry option as the default works fine as is.

	Removed win/tclWinInit.c from the special case section to let it
	use the common implicit rule as the $(EXTFLAGS) macro it had was
	never referenced anywhere.

2002-02-20  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tcl.h: Added code to guess the correct settings for
	TCL_WIDE_INT_IS_LONG and TCL_WIDE_INT_TYPE when configure doesn't
	tell us them, as can happen with extensions.

2002-02-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/format.n: Updated docs to list the specification.
	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Made behaviour on 64-bit
	platforms correctly meet the specification, that %d works with the
	native word-sized integer, instead of trying to guess (wrongly)
	from the value being passed.

2002-02-19  Don Porter <dgp@users.sourceforge.net>

	* changes: First draft of updated changes for 8.4a4 release.

2002-02-15  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixPort.h: add strtoll/strtoull declarations for
	platforms that do not define them.

	* generic/tclIndexObj.c (STRING_AT): removed ptrdiff_t cast and
	use of VOID* in default case (GNU-ism).

2002-02-15  Kevin Kenny  <kennykb@acm.org>

	* compat/strtoll.c:
	* compat/strtoul.c:
	* compat/strtoull.c:
	* generic/tclIOUtil.c:
	* generic/tclPosixStr.c:
	* generic/tclTest.c:
	* generic/tclTestObj.c:
	* tests/get.test:
	* win/Makefile.vc: Further tweaks to the TIP 72 patch to make it
	compile under VC++.
	
2002-02-15  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* tclExecute.c:
	* tclIOGT.c:
	* tclIndexObj.c: Touchups to the TIP 72 patch to make it
	  compileable under Windows again. The changes are not complete,
	  there is one nasty regarding _stati64

2002-02-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	+----------------------+
	| TIP #72 IMPLEMENTED. |
	+----------------------+

	There are a lot of changes from this TIP, so please see
	http://purl.org/tcl/tip/72.html for discussion of
	backward-compatability issues, but the main ones modifications are
	in:

	* generic/tcl.h: New types.
	* generic/tcl.decls: New public functions.
	* generic/tclExecute.c: 64-bit aware bytecode engine.
	* generic/tclBinary.c: 64-bit handling in [binary] command.
	* generic/tclScan.c: 64-bit handling in [scan] command.
	* generic/tclCmdAH.c: 64-bit handling in [file] and [format]
	commands.
	* generic/tclBasic.c: New "wordSize" entry in ::tcl_platform.
	* generic/tclFCmd.c: Large-file support (with many consequences.)
	* generic/tclIO.c: Large-file support (with many consequences.)
	* compat/strtoll.c, compat/strtoull.c: New support functions.
	* unix/tcl.m4, unix/configure: 64-bit support and greatly enhanced
	cacheing.

	Most other changes, including all those in doc/* and test/* as
	well as the majority in the platform directories, follow on from
	these.

	Also coming out of the woodwork:
	* generic/tclIndex.c: Better support for Cray PVP.
	* win/tclWinMtherr.c: Better Borland support.

	Note that, in a number of places through the Unix part of the
	platform support, there are Tcl_Platform* references.  These are
	expanded into the correct way to call that particular underlying
	function, i.e. with or without a '64' suffix, and should be used
	by people working on the core in preference to the API functions
	they overlay so that the code remains portable depending on the
	presence or absence of 64-bit support on the underlying platform.

	***POTENTIAL INCOMPATIBILITY***: Extracted from the TIP

	SUMMARY OF INCOMPATIBILITIES AND FIXES 
	======================================

	The behaviour of expressions containing constants that appear
	positive but which have a negative internal representation will
	change, as these will now usually be interpreted as wide
	integers. This is always fixable by replacing the constant with
	int(constant).

	Extensions creating new channel types will need to be altered as
	different types are now in use in those areas. The change to the
	declaration of Tcl_FSStat and Tcl_FSLstat (which are the new
	preferred API in any case) are less serious as no non-alpha
	releases have been made yet with those API functions.

	Scripts that are lax about the use of the l modifier in format and
	scan will probably need to be rewritten. This should be very
	uncommon though as previously it had absolutely no effect.

	Extensions that create new math functions that take more than one
	argument will need to be recompiled (the size of Tcl_Value
	changes), and functions that accept arguments of any type
	(TCL_EITHER) will need to be rewritten to handle wide integer
	values. (I do not expect this to affect many extensions at all.)

2002-02-14  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* generic/tclIOCmd.c (Tcl_GetsObjCmd): Trivial fix for bug
	  #517503, a memory leak reported by Miguel Sofer
	  <msofer@users.sourceforge.net>. The leak happens if an error
	  occurs for "set var [gets $chan]" and leak one empty object.

2002-02-12  David Gravereaux <davygrvy@pobox.com>

	* djgpp/ (new directory)
	* djgpp/Makefile (new):
	* unix/tclAppInit.c:
	* unix/tclMtherr.c:
	* unix/tclUnixFCmd.c:
	* unix/tclUnixFile.c:
	* unix/tclUnixInit.c:
	* unix/tclUnixPort.h:  Early stage of DJGPP support for building
	Tcl on DOS.  Dynamic loading isn't working, yet.  Requires watt32
	for the TCP/IP stack.  No autoconf, yet.  Barely tested, but
	makes a working exe that runs Tcl in protected-mode, flat memory.
	[exec] and pipes will need the most work as multi-tasking on DOS
	has to be carefully.

	Tcl_ExternalToUtfDString, Tcl_UtfToExternalDString,

	restored Tcl_WinUtfToTChar to return (TCHAR *) and 
	Tcl_UtfToUniCharDString to return (Tcl_UniChar *).  Modified
	some callers.  This change recognizes that Tcl_DStrings are
	de-facto white-box objects.

	* generic/tclCmdMZ.c: corrected use of C++-style comment.

2002-02-06  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/scan.test:
	* generic/tclScan.c (Tcl_ScanObjCmd): corrected scan 0x... %x
	handling that didn't accept the 0x as a prelude to a base 16
	number.  [Bug #495213]

	* generic/tclCompCmds.c (TclCompileRegexpCmd): made early check
	for bad RE to stop checking further.

	* generic/tclCmdMZ.c (Tcl_RegsubObjCmd): added special case to
	search for simple 'string map' style regsub calls.
	Delayed creation of resultPtr object until an initial match is
	made, as the input string object can then be reused for no matches.
	(Tcl_StringObjCmd): optimization improvements to the STR_MAP
	algorithm for zero-length and nocase cases.

	* tests/regexp.test:
	* tests/regexpComp.test: extra code coverage tests.

	* tests/string.test: added 10.18 and 10.19 extra tests.

	* generic/regc_locale.c (casecmp): slight performance improvement.

2002-02-04  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* unix/tclUnixChan.c (FileOutputProc): Fixed [bug 465765] reported
	  by Dale Talcott <daletalcott@users.sourceforge.net>. Avoid
	  writing nothing into a file as STREAM based implementations will
	  consider this a EOF (if the file is a pipe). Not done in the
	  generic layer as this type of writing is actually useful to
	  check the state of a socket.

	* doc/open.n: Fixed [Bug 511540], added cross-reference to 'pid'
	  as the command to use to retrieve the pid of a command pipeline
	  created via 'open'.

2002-02-01  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd): handle quirky about case
	earlier to avoid shimmering problem.

2002-02-01  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* tests/io.test: io-39.22 split into two tests, one platform
	  dependent, the other not. -eofchar is not empty on the windows
	  platform.

2002-02-01  Vince Darley <vincentdarley@users.sourceforge.net>

	* generic/tcl.decls:
	* generic/tcl.h:
	* generic/tclInt.h: For each interface identified in the TIP 27
	  changes below as a POTENTIAL INCOMPATIBILITY, the source of the
	  incompatibility has been parameterized so that it can be
	  removed.  When compiling extension code against the Tcl header
	  files, use the compiler flag -DUSE_NON_CONST to remove the
	  irresolvable source incompatibilities introduced by the TIP 27
	  changes.  Resolvable changes are left for extension authors to
	  resolve.
	* generic/tclDecls.h: make genstubs

2002-01-30  Vince Darley <vincentdarley@users.sourceforge.net>

	* doc/FileSystem.3: added documentation for 3 public

	* unix/tcl.m4 (SC_LOAD_TCLCONFIG):
	* win/tcl.m4 (SC_LOAD_TCLCONFIG): Set TCL_LIB_SPEC,
	TCL_STUB_LIB_SPEC, and TCL_STUB_LIB_PATH to the
	values of TCL_BUILD_LIB_SPEC, TCL_BUILD_STUB_LIB_SPEC,
	and TCL_BUILD_STUB_LIB_PATH when tclConfig.sh is loaded
	from the build directory. A Tcl extension should
	make use of the non-build versions of these variables
	since they will work in both cases. This modification
	was described in TIP 34.

	* win/tclWinReg.c (regConnectRegistryProc,RecursiveDeleteKey)
	(DeleteKey,GetKeyNames,GetType,GetValue,OpenSubKey,SetValue):
	redid the CONSTification as previous changes caused failing tests.

	* tests/regexpComp.test (new):
	* generic/tclInt.h:
	* generic/tclBasic.c: added TclCompileRegexpCmd entry
	* generic/tclCompCmds.c (TclCompileStringCmd): corrected to return
	TCL_OUT_LINE_COMPILE instead of TCL_ERROR for parsing errors, so
	it only throws the error for runtime compile, in case the user
	modifies 'string'.
	(TclCompileRegexpCmd): first try at a byte-compiled regexp
	command.  It handles static strings and ^$ bounded static strings.
	(TclCompileAppendCmd): made TclPushVarName call always use
	TCL_CREATE_VAR as numWords is always > 2 at that point.

	* generic/tclExecute.c (TclExecuteByteCode:INST_LIST): correct
	possibly dangerous decr in macro call.

	* win/tclWinInit.c (TclpFindVariable): CONSTification touch-up

	* win/tclWinReg.c (OpenSubKey): corrected bug introduced in
	CONSTification that dropped pointer reference.

	* ChangeLog.2000 (new file):
	* ChangeLog: broke changes from 2000 into ChangeLog.2000 to reduce
	  size of the main ChangeLog.

2002-01-28  David Gravereaux <davygrvy@pobox.com>

	* generic/tclPlatDecls.h:  Added preprocessor logic to force a
	typedef of TCHAR when __STDC__ is defined when using the uncommon
	-Za compiler switch with the microsoft compiler.

2002-01-27  Don Porter <dgp@users.sourceforge.net>

2002-01-25  Mo DeJong  <mdejong@users.sourceforge.net>

	Make -eofchar and -translation options read only for
	server sockets. [Bug 496733]
	
	* generic/tclIO.c (Tcl_GetChannelOption, Tcl_SetChannelOption):
	Instead of returning nothing for the -translation option
	on a server socket, always return "auto". Return the empty
	string enclosed in quotes for the -eofchar option on
	a server socket. Fixup -eofchar usage message so that
	it matches the implementation.
	* tests/io.test: Add -eofchar tests and -translation tests
	to ensure options are read only on server sockets.
	* tests/socket.test: Update tests to account for -eofchar
	and -translation option changes.

2002-01-21  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

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

2002-01-17  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

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

2002-01-05  Don Porter <dgp@users.sourceforge.net>

	* doc/Tcl_Main.3:
	* generic/tclMain.c:  Substantial rewrite and expanded documentation
	of Tcl_Main to correct a number of bugs and flaws:

		* Interactive Tcl_Main can now enter a main loop, exit
		  that loop and continue interactive operations.  The loop
		  may even exit in the midst of interactive command typing
		  without loss of the partial command.  [Bugs 486453, 474131]
		* Tcl_Main now gracefully handles deletion of its master
		  interpreter.
		* Interactive Tcl_Main can now operate with non-blocking stdin
		* Interactive Tcl_Main can now detect EOF on stdin even in
		  mid-command.  [Bug 491341]
		* Added VFS-aware internal routines for managing the
		  startup script selection.
		* Tcl variable 'tcl_interactive' is now linked to C variable
		  'tty' so that one can disable/enable interactive prompts
		  at the script level when there is no startup script.  This
		  is meant for use by the test suite.
		* Consistent use of the Tcl libraries standard channels as
		  returned by Tcl_GetStdChannel(); as opposed to the channels
		  named 'stdin', 'stdout', and 'stderr' in the master interp,
		  which can be different or unavailable.
		* Tcl_Main now calls Tcl_Exit() if evaluation of [exit] in the
		  master interpreter returns, assuring Tcl_Main does not return.
		* Documented Tcl_Main's absence from public stub table
		* Documented that Tcl_Main does not return.
		* Documented Tcl variables set by Tcl_Main.
		* All prompts are done from a single procedure, Prompt.
		* Use of Tcl_Obj-enabled interfaces everywhere.

	* generic/tclInt.decls (TclGetStartupScriptPath,
	  TclSetStartupScriptPath): New internal VFS-aware routines for
	managing the startup script of Tcl_Main.
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c: make genstubs

	* generic/tclTest.c (TestsetmainloopCmd,TestexitmainloopCmd,
	  Tcltest_Init,TestinterpdeleteCmd):
	* tests/main.test (new):  Added new file to test suite that
	thoroughly tests generic/tclMain.c; added some new test commands
	for testing Tcl_SetMainLoop().

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

	* generic/tclUtf.c (Tcl_UniCharCaseMatch):
	* generic/tclUtil.c (Tcl_StringCaseMatch): Fault with matching
