2001-12-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* 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.
	* unix/configure: Regen.
	* unix/mkLinks.tcl: improved case-insensitive
	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>

	* unix/configure:
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Update
	SunOS 5.[0-6] target so that correct linker
	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
	  ports from flooding the event queue.

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

	* doc/CrtInterp.3:
	* generic/tclBasic.c: docs and comments corrections [Bug 493412]
	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
	  "gethostbyaddr" for address "0.0.0.0" to prevent delays on
	  Win/NT.

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

	* doc/Preserve.3: doc'd TCL_DYNAMIC use. [Patch #483989] (porter)

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/tclCompExpr.c (CompileMathFuncCall): removed the last
	  two overestimates of the necessary stack depth for bytecodes in
	  the fix of [Bug 483611].

2001-12-10  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

	* unix/tclUnixPipe.c (TclpCreateProcess): Applied Don Porter's
	  patch fixing bug #437489.

2001-12-10  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclEvent.c:
	* tests/event.test: fix background error reporting in the absence
	of a bgerror proc [Bug 219142].

2001-12-10  Don Porter <dgp@users.sourceforge.net>

	* doc/Access.3:
	* doc/CrtChannel.3:
	* doc/DString.3:
	* doc/ExprLong.3:
	* doc/FileSystem.3:
	* doc/GetStdChan.3:

	* doc/TCL_MEM_DEBUG.3:
	* doc/Tcl_Main.3:
	* doc/Utf.3:
	* doc/file.n:
	* doc/tclsh.1:  Several typo and formatting corrections discovered
	during conversion to TMML.  Thanks to Joe English.  [Patch 490514]
	* unix/mkLinks: 'make mklinks'

2001-12-10  Miguel Sofer  <msofer@users.sourceforge.net>

	* generic/tclCompCmds.c:
	* generic/tclCompExpr.c:
	* generic/tclCompile.c:
	* generic/tclCompile.h:
	* generic/tclExecute.c:
	* generic/tclProc.c: fixed the calculation of the maximal stack
	depth required by bytecodes [Bug 483611].

2001-12-07  Miguel Sofer  <msofer@users.sourceforge.net>

	* 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/expr-old.test, tests/expr.test, tests/for.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/configure.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

	* 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

	* tools/eolFix.tcl (new-file):
	* unix/Makefile.in: added EOL correction for Windows bat files to

	* 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  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]

	* unix/configure: regened

	* 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.

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.

	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.

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.

2001-11-04  Vince Darley  <vincentdarley@users.sourceforge.net>

	* library/init.tcl: made filesystem fallback proc
	::tcl::CopyDirectory more robust to vagaries of non-native
	filesystems.
	
2001-11-02  Vince Darley  <vincentdarley@users.sourceforge.net>

	* doc/file.n:

2001-10-29  Vince Darley  <vincentdarley@users.sourceforge.net>

	* win/tclWinFile.c: fix to '-types {f r}' bug in
	TclpMatchInDirectory (which could cause a UMR, as well as
	returning wrong results).  Also improved API for 'stat'
	to resolve [Bug#219258].
	* win/tclWin32Dll.c
	* win/tclWinInt.h: addition of improved stat API to internal 
	lookup table.
	* tests/fileName.test: two new tests for the above bug.
	* generic/tclIOUtil.c: some cleanup of comments and #ifdefs
	
2001-10-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* unix/tclUnixFile.c (TclpMatchInDirectory): Argument to access()
	was entryPtr->d_name instead of nativeEntry which failed when
	trying to check access for files in other than the current
	directory. [Bug 475941, reported by Georgios Petasis]

2001-10-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* unix/tclUnixChan.c: Added stateUpdated member to struct TtyState.
	(TtyCloseProc,TtySetOptionProc,TtyInit): Use stateUpdated member
	of TtyState to decide whether it is necessary to reset a serial
	port when Tcl closes it.  Blindly resetting can cause Tcl to be
	sent an unexpected SIGTSTP when it is executing in the background
	[Bug 471374, reported by Chris Nelson]

2001-10-22  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	the style guide. 
	
2001-10-15  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

	* generic/tclInt.decls (TclExpandCodeArray,TclGetInstructionTable):
	  Added to internal stubs table. Tclcompiler (Tclpro project)
	  needs them if used as loadable package under Windows. Changed
	  signatures. We don't want to describe compiler internal
	  structures in "tclInt.h".

	* generic/tclCompile.h: S.a. Removed function declarations.

	* tests/compile.test: new tests for [Bug 467523]; they are only
	effective if TCL_MEM_DEBUG was set during compilation.

2001-10-11  Miguel Sofer  <msofer@users.sourceforge.net>
	
	* generic/tclLiteral.c (TclReleaseLiteral): insured that
	self-referential bytecodes are properly cleaned up on interpreter
	deletion [Bug 467523] (Ronnie Brunner)

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

	* win/tclWinPort.h:  #include <winsock2.h> needed to get moved
	to after #include <windows.h> or wierd misunderstandings took
	place when -D_WIN32_WINNT=0x0400 is set for outside code that
	requires knowledge of Tcl innards.  General header macro magic
	applied liberally...

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

	* tests/unixInit.test:	Corrected restore of ::env(LANG).

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

	* generic/tclFileName.c (Tcl_SplitPath): corrected mem leak
	intro'd with VFS code where the result obj from Tcl_FSSplitPath
	was not getting freed.

2001-10-09  Miguel Sofer  <msofer@users.sourceforge.net>
	
	* generic/tclLiteral.c: (TclReleaseLiteral) reverted previous
	patch for [Bug 467523] - cure is worse than the illness.

	not include big5, gb or euc* as those have different formats in

	* win/configure: regen'ed
	* win/tcl.m4:

	* generic/tclCmdIL.c:

	offset-from-end indexing work, and factored out some "magic
	numbers" for easier understanding.  [Bug #465674]
	* tests/cmdIL.test (cmdIL-1.26): Added test for offset-from-end
	indexing for lsort.

	* unix/tclUnixFCmd.c: fix to performance issue reported
	by jcw in which 'access("")' is called unnecessarily when
	normalizing any absolute path.
	* generic/tclIO.c: added '(ClientData)' cast to calls to
	Tcl_(Preserve|Release) newly introduced, fixing compile

	* generic/tclIntDecls.h: make genstubs

2001-09-26  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

	* doc/fileevent.n: Accepted [Patch #465279] adding an example to
	  the fileevent manpage. Minor modifications to get a better
	  formatting. Report and patch by David N. Welton
	  <davidw@users.sourceforge.net>.

	* The changes below fix [Bug #462317] where Expect tried to read
	  more than was in the buffers and then blocked in the OS call as
	  its pty channel driver provides no blockmodeproc through which
	  the OS could be notified of blocking-behaviour. Because of this
	  the general I/O core has to take more care than usual to
	  preserve the semantics of non-blocking channels.

	  The problem was reported by "Kevin O'Gorman"
	  <kevin@kosmanor.com>.

	* generic/tclIO.c (Tcl_ReadRaw): Do not read from the driver if
	  the channel is non-blocking and the fileevent causing the read
	  was generated by a timer. We do not know if there is data
	  available from the OS. Instead of going to the OS for more and
	  potentially blocking we simply signal EWOULDBLOCK to the higher
	  levels to cause the system to wait for true fileevents.
	  (GetInput): Same as before.
	  (ChannelTimerProc): Added set and clear of CHANNEL_TIMER_FEV.

	* generic/tclIO.h (CHANNEL_TIMER_FEV): New flag for channels. Is
	  set if a fileevent was generated by a timer, the channel is not
	  blocking and the driver did not provide a blockmodeproc. In that
	  case the I/O core has to be especially careful about going to
	  the driver for more data.

	* The change below fixes [Bug #464380]. The bug was reported by
	  Ronnie Brunner <rbrunner@users.sourceforge.net>. He also
	  provided the patch.
	
	* generic/tclEvent.c (Tcl_Finalize): Moved release of
	  'tclLibraryPath' to Tcl_FinalizeThread.
	  (Tcl_FinalizeThread): See above, new place for release of
	  'tclLibraryPath'.

2001-09-24  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tools/encoding/cp1252.txt: File was missing part of the encoding
	  [euro, ZCaron and zcaron].

	* doc/OpenFileChnl.3: Add docs for Tcl_OutputBuffered; remove some
	  old changebars.

2001-09-21  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclExecute.c (TclExecuteByteCode): corrected
	  INST_STR_CMP else case for strings to pass true utf char length
	  to Tcl_UtfNCmp.

2001-09-20  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinInit.c: added extra processor definitions. (mstacy)

	* win/tclWinSock.c (SocketThread): corrected pointer cast for _WIN64.

	* win/tclWinNotify.c: removed unnecessary winsock include (it is
	  already in from tclWinPort.h).

	* win/tclWinPort.h: changed winsock.h include to winsock2.h.
	  Reverses change from 2000-11-16, but is necessary for WIN64.
	  Extensions should comply with defined OS words, or use #ifndef.

2001-09-20  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tests/socket.test: removed dependence on being run from same dir
	  as remote.tcl, which only now needs to be in the same dir as
	  this file.  [Bug #219326]

2001-09-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclTest.c (TestcmdtokenCmd): corrected pointer
	  storage/retrieval for 64bit machines.

	* generic/tclCmdAH.c (Tcl_FormatObjCmd):
	* generic/tclScan.c (Tcl_ScanObjCmd): corrected handling of format
	and scan on 64-bit machines. [Bug #412696] (rmax)

	* unix/configure: regen'ed
	* unix/tcl.m4: added --enable-64bit support for HP-11 with the
	64-bit kernel.

	* tests/basic.test:
	* tests/cmdInfo.test: improved skip reporting of missing commands

	* tests/winFCmd.test: simplified error check for winFCmd-7.9

	* tests/winPipe.test: removed obsolete cat16 tests

	* generic/tclExecute.c (TclExecuteByteCode): fixed invalid usage
	of valuePtr in TRACE_WITH_OBJ in INST_EVAL_STK case. [Bug #462594]
	Changed INST_STR_CMP instruction to promote to Unicode strings
	only when one of the strings is already of Unicode type.

	* generic/tclExecute.c (TclExecuteByteCode):
	* generic/tclCompile.c (instructionTable):
	* generic/tclCompCmds.c (TclCompileStringCmd): INST_STR_MATCH -
	Updated to Int1 instruction type and added special case to use
	INST_STR_EQ instead when no glob chars are specified in a static
	string.

	* tests/{for.test,foreach.test,if.test,while.test}:
	* generic/tclCompCmds.c (TclCompileForCmd, TclCompileForeachCmd,
	TclCompileIfCmd, TclCompileWhileCmd): Corrected the overaggressive
	compiling of loop bodies enclosed in ""s.  [Bug #219166] (msofer)

2001-09-19  Miguel Sofer  <msofer@users.sourceforge.net>
	
	* generic/tclExecute.c: insured that execution stack errors are
	also detected at abnormal returns.

2001-09-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* doc/socket.n: Added documentation to mention what happens when a
	server socket is created with port=0.  Removed an old change bar,
	and no new change bar because Tcl has always behaved this way as
	it is really a poorly-documented standards-defined OS feature.

	* tests/util.test (util-8.1): Test derived from code to detect the
	problem, but the test always works in the C locale, so beware if
	you are maintaining the code.
	* generic/tclUtil.c (TclNeedSpace): Rewrote to be UTF-8 aware.
	[Bug 411825, but not that patch which would have added extra
	spaces if there was a real non-ASCII space involved. ]

2001-09-18 Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

	* generic/tclIOCmd.c (Tcl_PutsObjCmd): Rewritten to have saner and
	  faster argument handling.  Fixes bug #123552. Patch provided by
	  Donal K. Fellows <fellowsd@cs.man.ac.uk>: #402564.

2001-09-18  Don Porter  <dgp@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): On Linux, disable inlining when
	one of the compat/*.c routines is to be linked in. [Patch 440891]

2001-09-17  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tcl.h: removed forced #define USE_TCLALLOC 1 for
	Windows.  This means the native system allocator will be used by
	default.  This should be binary and source compatible with
	extensions, as Tcl_Alloc is a properly stubbed function.

2001-09-17  Miguel Sofer  <msofer@users.sourceforge.net>
	
	* generic/tclExecute.c: corrected small bug in [Patch 456668] -
	the varFramePtr was not restored in one possible exit.

2001-09-17  Miguel Sofer  <msofer@users.sourceforge.net>
	
	* doc/tclvars.n:
	* generic/tclCompile.c:
	* generic/tclCompile.h:
	* generic/tclExecute.c:
	* generic/tclProc.c: disabled all compile and execution tracing
	functionality in standard builds; TCL_COMPILE_DEBUG is now
	necessary to enable it. [Bug 451858]

2001-09-13  Jeff Hobbs  <jeffh@ActiveState.com>

	* tests/regexp.test (regexp-20.1):
	* generic/tclCmdMZ.c (Tcl_RegsubObjCmd): had to adjust fix from
	2001-08-06 to actually duplicate the objects in certain cases.
	This is really a place where feather would have been essential.
	[Bug #461322]

	* generic/tclUtf.c (Tcl_UtfPrev): corrected to return the proper
	location when the middle of a UTF-8 byte was passed in.
	[Tk Bug #450504]

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

	will have to be this with Borland:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

2001-08-23  Jeff Hobbs  <jeffh@ActiveState.com>

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

	8.4a3 RELEASE

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

	* generic/tclInt.decls:

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

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

	* mac/tclMacAppInit.c (main, Macintosh_Init):

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

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

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

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

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

	* doc/Panic.3:

	followed by `make mklinks`.  [Patch 415648, Bug 219170, Bug 414936]

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

	* generic/tclUtil.c (Tcl_DStringAppendElement): patch to save an

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

	* generic/tclExecute.c (TclExecuteByteCode): Added two casts to

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

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

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

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

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

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

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

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

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

	* generic/tclVar.c (tclArraySearchType,SetArraySearchObj,

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

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

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

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

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

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

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

	* generic/tclExecute.c: removed Tcl_DuplicateObj in INST_DUP 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

2001-05-15  Miguel Sofer  <msofer@users.sourceforge.net>

2001-05-15  Miguel Sofer  <msofer@users.sourceforge.net>

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

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

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

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

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

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

	* unix/Makefile.in: Add a LDFLAGS variable to the
	Makefile instead of directly substing @LDFLAGS@.
	* unix/configure: Regen.
	* unix/tcl.m4: Fix CFLAGS_DEFAULT so that the name
	of a Makefile variable is passed as @CFLAGS@.
	* win/Makefile.in: Move the setting of CFLAGS
	higher up in the Makefile.
	* win/configure: Regen.
	* win/configure.in: Use dnl to comment out macros
	so that they are not accidently expanded.

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

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

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

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

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

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

2001-04-27  Kevin Kenny	<kennykb@crd.ge.com>

	commands instead of using a delayed subst variable. Replace
	instances of STUB_LIB_FILE with TCL_STUB_LIB_FILE.

2001-04-25  Mo DeJong  <mdejong@redhat.com>

	* unix/Makefile.in: Use TCL_STUB_LIB_FILE instead of STUB_LIB_FILE.
	* unix/configure: Regen.
	* unix/configure.in: Don't subst STUB_LIB_FILE, use TCL_STUB_LIB_FILE
	instead.

2001-04-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

	* tools/encoding/iso8859-15.txt:

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

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

	* unix/tclUnixTime.c: Fixed silly typo in calls to 'gmtime' and

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

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

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

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

	* library/init.tcl:
	* tests/init.test:  Modified processing of $::errorInfo by

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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