	* library/init.tcl: make sure env(COMSPEC) on Windows is executed

	with the right case, as it may otherwise fail inexplicably.

2001-12-28  Don Porter <dgp@users.sourceforge.net>

	* generic/tclCkalloc.c (MemoryCmd, TclFinalizeMemorySubsystem):

	Added the [memory onexit] command, intended to replace [checkmem].

	* doc/DumpActiveMemory.3: 

	* doc/memory.n: Updated documentation for [memory] and related

	matters.  [Bug 487677]

	* mac/tclMacBOAMain.c (Tcl_Main, CheckmemCmd): Removed all the

	machinery for the [checkmem] command that is completely duplicated

	by code in generic/tclCkalloc.c.

	* generic/tclBinary.c:

	* generic/tclListObj.c:

	* generic/tclObj.c:

	* generic/tclStringObj.c: Removed references to [checkmem] in

	comments, referencing [memory active] instead, since it is

	documented.

2001-12-28  Daniel Steffen <das@users.sourceforge.net>

	* mac/tclMacInit.c:

	* mac/tclMacTclCode.r: synced up tclInit features to unix/win:

	implemented TclSetPreInitScript support, use of existing tclInit 

	proc if defined, check of default encoding dir if set. Changed

	script library resource names to lowercase (i.e. same as

	corresponding files). Used Tcl_JoinPath instead of string append.

	Check that system encoding could be loaded before utf translating

	the LibraryPath.

	* mac/tclMacApplication.r:

	* mac/tclMacLibrary.r:

	* mac/tclMacOSA.r:

	* mac/tclMacResource.r: minor version resources cleanup

2001-12-21  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/tcl.m4 (SC_PATH_TCLCONFIG, SC_PATH_TKCONFIG):

	Search for config file using exec_prefix instead of

	prefix when no --with-tcl or --with-tk argument is used. [Bug 492418]

2001-12-21  Daniel Steffen <das@users.sourceforge.net>

	* unix/tcl.m4: fixed incorrect SHLIB_LD_LIBS

	setting for MacOSX / Darwin.

	filesystem support.

	* unix/mkLinks: Regen.

2001-12-19  Don Porter <dgp@users.sourceforge.net>

	* unix/Makefile.in (dist): corrected use of eolFix.tcl on

	working files.  It should operate on distributed files.  [Bug 495120]

2001-12-19  David Gravereaux <davygrvy@pobox.com>

	* tools/tcl.wse.in: Fix for #495120.  tcl.wse.in was

	stored in cvs with improper <eol>.  This resulted in

	corrupted <eol> when checked-out on translating CVS

	clients such as windows (CRCRLF) and mac (CRCR).

2001-12-19  Mo DeJong  <mdejong@users.sourceforge.net>

	options are passed to gcc or ld. [Tk Bug 220863]

2001-12-19  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/README: Update to account for changes

	in the unix/dltest directory, the way autoconf

	is run, and the new "make shell" target.

2001-12-19  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in: Rename dltest to dlpkgs to

	fix problem where lib files were not getting

	built because dltest/ directory already existed.

2001-12-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinSerial.c (SerialCheckProc): corrected time

	calculations to be unsigned. (schroedter)

2001-12-18  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in: Define new dltest target that

	simply does a cd to dltest/ before running make.

	There is no need for the separate configure

	script that was previously being used.

	* unix/configure: Regen.

	* unix/configure.in: Subst into dltest/Makefile.

	* unix/dltest/Makefile.in: Define LIBS using

	DL_LIBS, LIBS, and MATH_LIBS variables instead

	of TCL_LIBS variable from tclConfig.sh.

	* unix/dltest/README: Update readme to account for new

	configure free implementation.

	* unix/dltest/configure: Removed.

	* unix/dltest/configure.in: Removed.

2001-12-18  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tcl.h (TCL_STUB_MAGIC): Added cast to force type to be

	an int and get rid of a persistent and pointless warning with

	SunPro compiler.

	* generic/tclCkalloc.c (Tcl_AttemptDbCkalloc,Tcl_AttemptDbCkrealloc): 

	* generic/tcl.decls (Tcl_AttemptDbCkalloc,Tcl_AttemptDbCkrealloc):

	Made the file parameters to these functions into CONST char *,

	like they always should have been to match the other Tcl*Db* API

	functions.

2001-12-17  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

	* Applied #219311 on behalf of Rolf Schroedter

	  <schroedter@users.sourceforge.net> to prevent fcopy on serial

	Bug & patch by Don Porter.  

2001-12-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* win/tclWinNotify.c (Tcl_FinalizeNotifier): Stop Tcl on Windows

	from crashing when shutdown from a non-Tcl thread. Fixes Bug

	#217982 [orig. 5804] reported by Hugh Vu and Gene Leache.   I'm

	not convinced that the shutdown process is right even with this,

	but it was definitely wrong without...

2001-12-13  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

	* win/tclWinSock.c (TcpGetOptionProc): Fix for tcl bug item

	  #478565 reported by an unknown person. Bypasses all calls to

2001-12-12  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

	* generic/tclIO.c (Tcl_GetsObj): Applied patch for bug #491341 as

	  provided by Don Porter <dgp@users.sourceforge.net>. Fixes the

	  assumption of having an empty Tcl_Obj to work with.

2001-12-11  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompCmds.c:

	* generic/tclCompile.c:

	* generic/tclExecute.c: consistency patch, to make all

	  instructions that pop a variable number of Tcl_Obj's off the

	  execution stack take the number of popped objects as first

	  operand. Modified *only* the new instructions

	  INST_LIST_INDEX_MULTI and INST_LSET_FLAT, so this has no effect

	  on bytecodes generated up to tcl8.4a3 inclusive.

	* generic/tclExecute.c: fix debug messages in INST_LSET_LIST. 

	* generic/tclCompCmds.c (TclCompileLindexCmd):

	* generic/tclVar.c: 

	* tests/trace.test: restored consistency in refCount accounting by

	array traces [Bug #4484339], submitted by Don Porter. 

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

	* tests/parseExpr.test, tests/for.test, tests/expr.test:

	* tests/expr-old.test, tests/compile.test, tests/compExpr.test

	* tests/compExpr-old.test: Kept up to date with syntax errors.

	* generic/tclParseExpr.c (ParsePrimaryExpr): Rewrote to give even

	better syntax errors in the fairly common case of an identifier

	without decorations by guessing based on the currently available

	functions.  Also made messages consistent between memdebug and

	ordinary builds.

2001-12-05  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclVar.c: 

	* tests/trace.test: new algorithm for [array get], safe when there

	are traces that modify the array [Bug #449893]. 

2001-12-04  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/compExpr-old.test, tests/compExpr.test, tests/compile.test:

	* tests/while.test, tests/if.test: Rewrite to handle more specific

	syntax errors.

	* tests/parseExpr.test: Rewrite to get rid of dup test numbers and

	handle more specific syntax errors.

	* generic/tclParseExpr.c (LogSyntaxError): Added a detail message

	argument to help explain what the syntax error is.

	(Tcl_ParseExpr, ParseCondExpr, ParsePrimaryExpr): Added detail

	messages.

	(UNKNOWN_CHAR): New lexeme for characters that are always illegal

	in expressions outside strings.

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

	* doc/expr.n: Various documentation improvements in relation to

	the function calls.  Includes fix for Bug #487704 submitted by

	Devin Eyre.

2001-12-03  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc: Some install target bugs repaired along with

	$(TCLSTUBLIB) added to the dependencies rather than implicit through

	the dde and reg extensions which don't happen to always require it

	for some build types.

2001-11-30  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclVar.c: Tcl_Preserve'ing VarTrace structures to avoid 

	memory corruption. Patch for [Bug: 484334] provided by Don Porter 

2001-11-29  Miguel Sofer  <msofer@users.sourceforge.net>

	* tests/namespace.test: modified namespace-41.2, added 41.3

	{knownbug} after discussion with Don Porter and Kevin Kenny.

2001-11-29  Miguel Sofer  <msofer@users.sourceforge.net>

	* tests/namespace.test: added namespace-41.2, a simpler test for

	[Bug: 231259]

2001-11-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* generic/tclBinary.c (BINARY_SCAN_MAX_CACHE, Tcl_BinaryObjCmd,

	ScanNumber): Added caching scheme to reduce number of object

	allocations when doing scans of large repetitive binary strings.

	See comments in file for reasoning behind implementation.

	Suggested by Miguel Sofer in Patch #429916, but independently

	implemented.

2001-11-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/regsub.n, doc/regexp.n: Converted dangling references to

	METASYNTAX section into references to the re_syntax manual page.

2001-11-27  D. Richard Hipp   <drh@hwaci.com>

	* win/tclWinFCmd.c: Fix a coredump in the filename normalizer

	code for Win95/98.

2001-11-27  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc: Removed the Tk reference for the 'winhelp' target.

	Converge at install will need to be the solution for Tk and all other

	extensions.

2001-11-27  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/cmdAH.test (cmdAH-24.2): Made test less sensitive to OS

	preemption, but perfection isn't practical [Bug 463189, reported

	by Don Porter.]

	* tests/switch.test (switch-9.*): Added tests to exercise more of

	the argument checking.  (switch-7.2,switch-7.3): Test changed

	behaviour slightly.

	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Reworked argument parsing

	to be stricter about what it accepts.  This should make uses of

	the [switch] command be more maintainable.  [Bug 475397, reported

	by Don Porter.]

2001-11-26  Don Porter <dgp@users.sourceforge.net>

	* generic/tclIntPlatDecls.h: 'make genstubs' after changes

	in 2001-11-23 commit from Daniel Steffen.

2001-11-24  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in: Add comments to better describe

	TCL_EXE and when it should be available.

	* win/Makefile.in: Add TCL_EXE variable to be used

	by rules like `make genstubs`. Don't set TCL_LIBRARY

	before running `make genstubs` since we will be running

	with a tclsh from the PATH not the one we build.

2001-11-24  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.

	* win/tcl.m4 (SC_CONFIG_CFLAGS): Add comctl32.lib

	to wish link libs. This change was originally added

	to Tk on 2001-11-09 but was not committed to Tcl.

2001-11-23  Daniel Steffen <das@users.sourceforge.net>

	* unix/Makefile.in:

	* unix/install-sh:

	* unix/mkLinks:

	* unix/mkLinks.tcl:

	* unix/tclLoadDyld.c:

	* unix/tclMtherr.c: Mac OSX support: build system, dynamic code loading

	and support for case-insensitive filesystems in mkLinks (patch #435258)

2001-11-23  Daniel Steffen <das@users.sourceforge.net>

	Up-port to 8.4 of mac code changes for 8.3.3 & various new

	changes for 8.4, some already backported to 8.3.4 (patch #435658)

	* generic/tclObj.c: added #include to fix missing prototype errors

	* generic/tcl.h: MAC_TCL: addition of ConditionalMacros.h and use of

	DLLIMPORT and DLLEXPORT like on other platforms.  ( => no longer need

	the .exp files and can remove use of #pragma export that never worked

	well)

	removed line continuation in #if clause as this breaks the mac

	resource compiler (note that *.r files include tcl.h)

	* mac/tclMacFile.c: fixed bug in permission checking code

	* mac/tclMacLoad.c: corrected utf8 handling, comparison of

	package names to code fragment names changed to only match on the

	length of package name, this allows for fragment names with version

	numbers appended

	* mac/tclMacInt.h:

	* generic/tclInt.h:

	* mac/tclMacTime.c:

	* generic/tclIOUtil.c: moved declaration of TclpGetGMTOffset()

	* mac/tclMacShLib.exp:

	* mac/tclMacOSA.exp:

	* mac/tclMacMSLPrefix.h: removed files

	* unix/Makefile.in: removed reference to .exp files

	* mac/MW_TclBuildLibHeader.h:

	* mac/MW_TclBuildLibHeader.pch:

	* mac/MW_TclHeaderCommon.h:

	* mac/MW_TclStaticHeader.h:

	* mac/MW_TclStaticHeader.pch: new precompiled header files

	* mac/MW_TclAppleScriptHeader.pch:

	* mac/MW_TclHeader.pch:

	* mac/MW_TclTestHeader.pch:

	* mac/tclMacCommonPch.h: revised precompiled header handling: now

	include a common header file 'MW_TclHeaderCommon.h' from all .pch

	files, the .pch files themselves now only setup #defines (e.g.

	BUILD_tcl, STATIC_BUILD, TCL_DEBUG, TCL_THREADS) like in makefiles on

	other platforms.

	* mac/tclMac.h:

	* mac/tclMacPort.h:

	* mac/tclMacInt.h: use of BUILD_tcl and TCL_STORAGE_CLASS like on other

	platforms, standardize #include'd files to what's done on other

	platforms, removed use of #pragma export.

	* mac/tcltkMacBuildSupport.sea.hqx: new archive of mac build support

	files & suggested build environment directory hierarchy: 

	'Building MacTclTk' & 'CW Pro6 changes' readme's.

	projects for MoreFiles 1.5.2 static & shared libraries.

	project & sources for 'pseudoCarbonSupport', see below.

	included XML versions of the projects for CW Pro5 or Pro7 users.

	* mac/tclMacProjects.sea.hqx: updated mac build project files:

	build support for CodeWarrior Pro6, UnivIntf 3.4 & shared runtime

	libraries: the MSL libraries and MoreFiles are no longer compiled into

	Tcl.shlb, all non-static binaries now use the Pro6 shared runtime

	libraries and MoreFiles.shlb.  These shlbs are merged into the standard

	Wish and TclShell, but 3rd party applications linking with Tcl.shlb or

	Tk.shlb need to setup access to them.  (see the "(sh-ppc)" targets

	for how to do this.)

	included XML versions of the projects for CW Pro5 or Pro7 users.

	use compat/strtod.c instead of MSL's strtod()

	use WASTE versions of MSL for tcl test target to avoid text buffer

	cutoff at 32k.

	Merging the full MSL.shlb and the other shlbs into Wish & TclShell

	makes them a bit larger than before, use unmerged binaries to avoid

	copying the shared code with every application, e.g. when deploying

	numerous Wish based droplets.

	Note that using CW Pro5 to compile extensions is in principle still

	possible, but need to link with Pro6 runtime libraries.

	Tclapplescript now loads and runs on CFM68k.

	Highly experimental "pseudoCarbon" support for Tcl only on OS 8/9:

	binaries in "Build:(Carbon):" link against CarbonLib instead of

	InterfaceLib, however the actual code has not been carbonized! i.e. it

	will not run on OSX and may not even run properly with CarbonLib. 

	This should in principle allow you to build & test OS9 CFM Carbon

	binaries that need to link with Tcl.shlb.  On OSX you can use the

	native Tcl.framework, but you have to build a MachO binary as there

	is no CFM glue lib for Tcl.framework.

	the library pseudoCarbonSupport.shlb manually loads the symbols

	from InterfaceLib that are not in CarbonLib but are needed by the

	uncarbonized code in Tcl.shlb and TclShell.

	* generic/tclMain.c: MAC_TCL: workaround for broken/non-standard isatty

	on MW Pro6, #include <unistd.h> instead of defining isatty

	* mac/tclMacPort.h: MW Pro6 changes for MSL fcntl.h, stat.h & isatty

	* mac/tclMacAppInit.c: add EXTERN to InstallConsole to enable DLL

	export via the TCL_STORAGE_CLASS mechanism.

	* mac/tclMacFCmd.c: fix for FSpDirectoryCopy API change

	* mac/tclMacLibrary.c: emit compile time error when

	TCL_REGISTER_LIBRARY and USE_TCL_STUBS are both defined at the same

	time in an extension, this use is not currently supported and will

	result in a crash when dynamically loading the extension.

	* mac/tclMacApplication.r:

	* mac/tclMacLibrary.r:

	* mac/tclMacOSA.r:

	* mac/tclMacResource.r: fixed obsolete copyrights/dates in version

	strings; updated version strings to standard usage; added support for

	'(Support Libraries)' subfolder for shared runtime libraries in

	unmerged binaries; commented out demo setting of "Tcl Environment

	Variables"; reorganized resources among these files to avoid 

	multiple copies in applications and shared libraries, the script

	libraries are now no longer duplicated in Tclsh but are only included 

	in the resources of Tcl.shlb.

	* mac/tclMacChan.c:

	* mac/tclMacSock.c: cast for *BlockMode

	* mac/tclMacUtil.c:

	* mac/tclMacMath.h: removed obsolete hypot() definition

	* generic/tclIntPlatDecls.h:

	* generic/tclInt.decls:

	* generic/tclStubInit.c:

	* mac/tclMacNotify.c:

	* mac/tclMacOSA.c:

	* mac/tclMacUtil.c:

	* generic/tclThreadTest.c: renamed routines conflicting with standard

	Apple or MoreFiles headers (at compile or link time):

	GetGlobalMouse         -> GetGlobalMouseTcl

	FSpGetDirectoryID      -> FSpGetDirectoryIDTcl

	FSpOpenResFileCompat   -> FSpOpenResFileCompatTcl

	FSpCreateResFileCompat -> FSpCreateResFileCompatTcl

	NewThread              -> NewTestThread

	the renamed MoreFiles *Tcl routines are just wrappers calling into the

	MoreFiles DLL.

	* mac/tclMacCommonPch.h:

	* mac/tclMacThrd.c:

	* mac/tclMacPanic.c: removed OLDROUTINENAMES define, renamed obsolete

	apple API names to modern equivalents; UH3.4 support: added #include

	<ControlDefinitions.h>, updated New*Proc() calls to New*UPP().

	* mac/tclMacUnix.c: added missing (Tcl_Obj ***) cast to

	Tcl_ListObjGetElements call

	* mac/tclMacAlloc.c: modernized TclpSysAlloc() to use temporary

	memory instead of system heap memory when available (MacOS

	>= 7.5 and possibly earlier, use of system heap has been

	discouraged for a long time and has many disadvantages, e.g. memory

	isn't paged out, and errors can very easily bring the system down);

	fixed crashing bug in TclpSysRealloc() and CleanUpExitProc() where

	memory was being accessed after having been deallocated; fixed

	memory leak in (de)allocation code (for every block ever allocated

	with TclpSysAlloc, a Ptr was leaked), if temporary memory is

	available, don't track allocated memory, instead use

	RecoverHandle() to get Handle from Ptr, otherwise use doubly linked

	list to correctly track memory and free all allocated memory; added

	new option for ConfigureMemory: MEMORY_DONT_USE_TEMPMEM, disables

	use of temporary memory even when it would be available, only

	necessary when writing e.g. a driver (using tcl??); increased

	fraction of application heap reserved for OS routines to 512K

	* compat/strftime.c: 

	* mac/tclMacTime.c:

	* mac/tclMacPort.h:

	* generic/tclInt.decls: 

	* generic/tclIntPlatDecls.h:

	* generic/tclStubInit.c: timezone support for mac via 

	TclpGetTZName() like on windows, using an inverse timezone table

	adapted from tclDate.c to map gmtoffset in seconds gotten from

	the MacOS APIs to a  timezone string, as there is no good way to get

	this info from MacOS. I had to make up some unusual timezones and

	arbitrarily decide on the most standard of the multiple choices

	available for every timezone.

	* generic/tclExecute.c: workaround for a MSL bug/misfeature: for

	very small floats, MSL can return errno ERANGE but a

	non-zero value ( < LDBL_MIN however)

	* mac/tclMacAppInit.c: support for WASTE text library using

	temporary memory, setting has no effect if WASTE is not used.

	* mac/tclMacPanic.c: removed duplicate code from generic/tclPanic.c

	and added that file to projects instead.

	* tests/all.tcl: set tcltest::singleProcess 1 as multiple processes

	are not available on the mac.

	* tests/cmdAH.test: access time not available on the mac, skip the 

	atime touch test

	* tests/appendComp.test:

	* tests/cmdMZ.test:

	* tests/compile.test:

	* tests/exec.test:

	* tests/fileName.test:

	* tests/lset.test:

	* tests/namespace.test:

	* tests/tcltest.test: added missing cleanups/tests/catches that

	caused tests to fail on the mac.

	* doc/tclvars.n: doc bug, env(PWD) should be env(HOME) [Bug 463834]

2001-11-21  Don Porter	<dgp@users.sourceforge.net>

	* tests/trace.test (trace-8.8): Corrected test for Bug 219393.

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken,CallCommandTraces):

	* generic/tclCmdMZ>c (Tcl_UntraceCommand):  Added Tcl_Preserve and

	Tcl_Release calls to prevent deletion of CommandTrace structures

	until all callers are done using them, preventing memory corruption.

	[Bug 453805]

	* win/tclWinNotify.c (Tcl_Sleep):

	* win/tclWinTest.c (TestwinclockCmd):

	* win/tclWinTime.c (TclpGetSeconds, TclpGetClicks, Tcl_GetTime):

	Changed all uses of TclpGetTime to Tcl_GetTime.  Added Tcl_GetTime

	to the Stubs table and the library documentation.  Added a

	TclpGetTime in tclUtil.c for backward compatibility of

	extensions. [Patch #483500, TIP#73]

	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): Corrected an error in the

	[time] command that caused incorrect results to be returned if the

	total duration of all iterations exceeded 2**31 microseconds.

	[Bug #478847]

	* generic/tclInt.decls:

	* generic/tclInt.h:

	* generic/tclStubInit.h: Reran 'make genstubs'

2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c

	* generic/tclCompile.h: 

	* generic/tclExecute.c: moving all code relative to bytecodes from

	tclBasic.c to tclExecute.c - the functions RecordTracebackInfo and

	Tcl_ExprObj went to tclExecute.c, and new interface function was

	defined (TclCompEvalObj).

	The final objective of this sequence of moves is to provide a

	clean, clear-cut interface between Tcl's core and the

	compiler/engine subsystem.  

2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c

	* generic/tclCompile.h: 

	* generic/tclExecute.c: factoring out of common code in tclBasic.c

	(new function TclInterpReady defined: it resets the interp's

	result, then checks that it hasn't been deleted and that the

	nesting level is acceptable). Passed the responsibility of calling

	it to the *callers* of TclEvalObjvInternal.

2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c

	* generic/tclExecute.c: a better variant of the previous-to-last

	commit (restoring numLevels computations). The managing of the

	levels now has to be done by the *callers* of TclEvalObjvInternal  

2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c: missing variable declaration under

	TCL_COMPILE_DEBUG. 

2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclExecute.c:

	* generic/tclProc.c: restoring the computations of iPtr->numLevels

	to the original logic (previous to buggy modifs on 2001-11-16).

2001-11-20  Jeff Hobbs  <jeffh@ActiveState.com>

	* tools/eolFix.tcl (new-file):

	* unix/Makefile.in: added EOL correction for Windows bat files to

	dist target. [Bug #219409] (davygrvy)

	* unix/tclUnixInit.c (TclpSetInitialEncodings): update of patch

	from 2001-11-16 that uses the old Tcl encoding check mechanism as

	a fallback to the original.  Also added a TCL_DEFAULT_ENCODING

	#define (defaults to iso8859-1).  Tcl will first try setlocale and

	nl_langinfo, and if that fails, guess based on certain LANG|LC_*

	env vars. [Patch #418645]

2001-11-19  David Gravereaux <davygrvy@pobox.com>

	* win/buildall.vc.bat:  Added useful comments.

2001-11-19  Miguel Sofer  <msofer@users.sourceforge.net>

	* tests/compile.test: added a test for bug [Bug 483309]

2001-11-19  Vince Darley  <vincentdarley@users.sourceforge.net>

	* win/tclWinFile.c:

	* win/tclWinFCmd.c:

	* win/tclWin32Dll.c:

	* doc/file.n:

	* tests/winFCmd.test: improved speed of file normalization

	for Win95/98, and clarified docs on differences in file

	normalization between NT/2000 and the older operating systems.

	Added test to ensure normalization is correct.

2001-11-19  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c:

	* generic/tclParse.c: Code reorganisation. Moved all evaluation

	functions from tclParse.c to tclBasic.c, so that now tclParse.c

	deals exclusively with parsing and all evaluations are done by

	code in tclBasic.c. The functions moved are: TclEvalObjvInternal,

	Tcl_EvalObjv, Tcl_LogCommandInfo, Tcl_EvalTokensStandard,

	Tcl_EvalTokens, Tcl_EvalEx, Tcl_Eval, Tcl_EvalObj and

	Tcl_GlobalEvalObj. 

2001-11-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/trace.test (trace-8.8): Added adapted version of Bug

	#219393 as new test; the test won't reliably show up the old

	problem unless it is being run under something like Purify, but

	something is better than nothing...

	* generic/tclVar.c (Tcl_TraceVar2, Tcl_UntraceVar2): Added missing

	mask bits for trace result type and a check for a nonsense flag

	combination.

	* generic/tclCmdMZ.c (TraceVarProc): Added missing test for NULL

	when deleting a trace that doesn't cause an error.

	* doc/TraceVar.3: Added documentation for change due to TIP#68.

	* generic/tclCmdMZ.c (TraceVarInfo): Removed problematic errMsg

	field from structure.

	(TraceVarProc): Removed references to errMsg field and changed

	handling of errors so that they returned a Tcl_Obj* containing the

	error string.  This minimizes the number of calls to the memory

	management subsystem.

	(TclTraceCommandObjCmd, TraceCommandProc): Removed references to

	errMsg field which was never used in command traces in any case.

	(Tcl_TraceObjCmd, TclTraceVariableObjCmd): Removed references to

	errMsg field and made variable traces register with

	TCL_TRACE_RESULT_OBJECT bit set.

	* generic/tcl.h (TCL_TRACE_RESULT_DYNAMIC,TCL_TRACE_RESULT_OBJECT): 

	New constants to define how to handle the strings returned from

	trace callbacks [TIP#68]

	* generic/tclVar.c (CallTraces, Tcl_GetVar2Ex, TclGetIndexedScalar,

	TclGetElementOfIndexedArray, Tcl_SetVar2Ex, TclSetIndexedScalar,

	TclSetElementOfIndexedArray, Tcl_UnsetVar2, Tcl_ArrayObjCmd,

	TclDeleteVars, TclDeleteCompiledLocalVars, DeleteArray,

	TclVarTraceExists): Support for those new trace flags.

2001-11-19  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompCmds.c: patch for [Bug 483309] (petasis).

2001-11-16  Kevin B. Kenny  <kennykb@users.sourceforge.net>

	* generic/tclListObj.c: removed a C++-style comment that

	  was inadvertently left in the source code.

2001-11-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/interp.test: 

	* generic/tclInterp.c (SlaveObjCmd): Corrected argument checking

	for '$interp alias|aliases|issafe'. [Patch #479560] (thoyts, hobbs)

	* unix/tclUnixInit.c: added HAVE_LANGINFO code block.

	* unix/configure: regened

	* unix/configure.in: added SC_ENABLE_LANGINFO call

	* unix/tcl.m4: made SHLIB_LD_LIBS='${LIBS}' for FreeBSD* (meyer)

	Added modified version of Wagner patch to make use of nl_langinfo

	where possible to determine Unix platform encoding, instead of the

	inflexible built-in system.  This is used by default when

	possible, and can be disabled with --enable-langinfo=no.

	[Patch #418645] (hobbs, wagner)

2001-11-16  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompile.h:

	* generic/tclExecute.c:

	* generic/tclObj.c: moved Tcl_GetCommandFromObj and all defining

	code for tclCmdNameType objects to tclObj.c (from tclExecute.c). 

	This code has nothing to do with bytecodes.

2001-11-16  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclBasic.c:

	* generic/tclCompile.h:

	* generic/tclExecute.c:

	* generic/tclParse.c:

	* generic/tclProc.c:

	* tests/stack.test: consolidation of duplicated code (in

	TclExecuteByteCode and EvalObjv); renaming of EvalObjv to

	TclEvalObjv as it is not static anymore; restored consistency of

	level counts between compiled and directly evaled code.

	[Bug 480896]

2001-11-12  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc:

	* win/rules.vc:  Small bug fixes.

	* win/README: added some docs pointing to the docs in makefile.vc

	for it's use.

	Reference implementation of TIP's #22, #33 and #45.  Adds the

	ability of the [lindex] command to have multiple index arguments,

	and adds the [lset] command.  Both commands are byte-code compiled.

	[Patch #471874] (work by Kenny, commited by Hobbs)

2001-11-12  David Gravereaux <davygrvy@pobox.com>

	* win/buildall.vc.bat(new):

	* win/makefile.vc:  Small fix with deriving the "OriginalFilename"

	string in the .rc scripts.  Added a quick batchfile for building

	the entire thing.

2001-11-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* doc/FileSystem.3:

	* doc/file.n:

	* doc/tcltest.n: converted use of \' to more reasonable format.

2001-11-10  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in:

	* win/Makefile.in: Add "make gdb" target. This target

	can run tclsh inside either gdb or insight.

2001-11-10  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc:  Added a check to make sure one runs the makefile

	from the /win directory only.

	* win/mkd.bat:

	* win/rmd.bat:  Changes from Llyod Lim for better stability.

	[Patch #456759]

2001-11-09  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc:

	* win/tcl.dsp:  winhelp target fixes for non-NT systems.  It

	seems NMAKE under these remembers changed directories during

	commands.   A new tcltest feature from Peter Spjuth 

	<peter.spjuth@space.se> to specify a pattern file from the

	commandline and redirecting output to a file when not under

	NT with it's scrollback console.  Then it replays it, piped

	through more.  Added 2 new static "configurations" to tcl.dsp.

	I could keep adding more, but I think we should leave it up to

	the user for customizing it.

	Sticky-points left:  'profile' option.

2001-11-09  Don Porter	<dgp@users.sourceforge.net>

	* tests/var.test:

	* generic/tclVar.c: Corrected bug in [global] when dealing

	with variable names matching :*.  [Bug 480176]

2001-11-08  Mo DeJong  <mdejong@users.sourceforge.net>

	Fixup stack size under OSF1. [Tcl patch 474790]

	* unix/configure: Regen.

	* unix/tcl.m4: Add HAVE_PTHREAD_ATTR_SETSTACKSIZE define

	to EXTRA_CFLAGS to adjust initial stack size.

2001-11-08  Mo DeJong  <mdejong@users.sourceforge.net>

	Enable thread support under FreeBSD. [Tcl bug 473708]

	* unix/configure: Regen.

	* unix/tcl.m4 (SC_ENABLE_THREADS): Check for pthread functions

	in libc_r and enable thread support if found.

	* unix/dltest/Makefile.in: Set SHLIB_LD_LIBS and use it in

	the Makefile to properly link a shared library.

2001-11-08  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in:

	* unix/dltest/Makefile.in:

	Avoid adding libc to the LIBS variable since it

	is not needed when linking with CC. If required

	when linking with LD it should be done on a case

	by case basis in tcl.m4.

2001-11-08  David Gravereaux <davygrvy@pobox.com>

	* win/rules.vc:

	* win/makefile.vc:  Fixed install target to adjust for the

	different build types.  Added a 'linkexten' option to link the

	win extensions inside the shell when built static.  Placed

	win/tclAppInit.c patch in SF patch DB for approval. 'profile'

	option not hooked in yet.  Everything else know is done.

	* win/tcl.dsp(new):

	* win/tcl.dsw(new):  Simple MsDev stub project files that calls

	makefile.vc.  Will help run Tcl in the debugger easier without

	confusing MsDev for where the .pdb files are.

2001-11-07  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/Makefile.in:

	* win/Makefile.in:

	Print a message indicating that the user should

	run "make genstubs" when the generated tclStubInit.c

	file is out of date. We can't regenerate automatically

	since there may be no tclsh on the system and that

	would cause bootstrap problems. [Tcl bug 465874]

2001-11-07  Mo DeJong  <mdejong@users.sourceforge.net>

	Define TCL_INCLUDE_SPEC in tclConfig.sh. It should be

	included by extensions that need to find Tcl include

	headers in the install location. The user can override

	the include install dir with --includedir so we need

	to record this information for extensions. [Tcl bug 421835]

	* unix/configure: Regen.

	* unix/configure.in: Define TCL_INCLUDE_SPEC.

	* unix/tclConfig.sh.in: Define TCL_INCLUDE_SPEC.

	* win/configure: Regen.

	* win/configure.in: Define TCL_INCLUDE_SPEC.

	* win/tclConfig.sh.in: Define TCL_INCLUDE_SPEC.

2001-11-07  David Gravereaux <davygrvy@pobox.com>

	* win/rules.vc:

	* win/makefile.vc: Dropped the NOMSVCRT macro and put it on the

	option list instead.  It makes more sense to me this way as

	NOMSVCRT=0 would only be the valid setting.  Fixed the dde and reg

	extension for building static.  Improved, but not perfected, the

	winhelp target.

2001-11-07  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/README: Change minimum VC++ version to 5.X since

	4.X is known not to work.

	Indicate that Mingw is required and building with Cygwin

	gcc is not supported. Include instructions that indicate

	how to install Mingw and what URLs folks should use to

	download the supported version of Mingw.

	* win/configure: Regen.

	* win/configure.in: Error out if user tries to compile the

	Windows version of Tcl with Cygwin gcc. Users should compile

	with Mingw gcc instead.

2001-11-06  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

	* generic/tclIO.c (ReadChars): Fixed bug #478856 reported by

	  Stuart Cassoff <stwo@users.sourceforge.net>. The bug caused loss

	  of fileevents when [read]ing less data from the channel than

	  buffered. Due to an empty input buffer the flag

	  CHANNEL_NEED_MORE_DATA was set but never reset, causing the I/O

	  system to wait for more data instead of using a timer to

	  synthesize fileevents and to flush the pending data out of the

	  buffers.

2001-11-06  David Gravereaux <davygrvy@pobox.com>

	* win/rules.vc (new):

	* win/makefile.vc:  Complete over/under rewrite to support numerous

	build options all from the commandline itself without needing to

	edit the makefile.  Now requires vcvars32.bat to be run prior to

	running nmake for bootstraping the environment.  Fully doc'd usage

	for it is in makefile.vc.  Commentary welcome.  Sticky points left

	are:

	1) winhelp target shows errors in the converting script.

	2) .rc scripts aren't getting the right #defines to build the correct

	   "OriginalFilename" strings. (have patch, won't commit yet)

	3) Naming convention with suffixes describing the buildtype are 'tsdx'

	   which will need public acceptance. ie. tclsh84tsx.exe is a (t)

	   threaded shell (s) statically linked to the core and (x) uses

	   msvcrt instead of libcmt.
