changelog.2001

tcl是工具命令语言

	* 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	<[e-mail]>

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

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken,CallCommandTraces):
	* generic/tclCmdMZ>c (Tcl_UntraceCommand):  Added Tcl_Preserve and
	Tcl_Release calls to prevent deletion of CommandTrace structures
	until all callers are done using them, preventing memory corruption.
	[Bug 453805]

2001-11-20  Kevin B. Kenny  <[e-mail]>

	* win/tclWinNotify.c (Tcl_Sleep):
	* win/tclWinTest.c (TestwinclockCmd):
	* win/tclWinTime.c (TclpGetSeconds, TclpGetClicks, Tcl_GetTime):
	Changed all uses of TclpGetTime to Tcl_GetTime.  Added Tcl_GetTime
	to the Stubs table and the library documentation.  Added a
	TclpGetTime in tclUtil.c for backward compatibility of
	extensions. [Patch #483500, TIP#73]

	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): Corrected an error in the
	[time] command that caused incorrect results to be returned if the
	total duration of all iterations exceeded 2**31 microseconds.
	[Bug #478847]

	* generic/tclInt.decls:
	* generic/tclInt.h:
	* generic/tclStubInit.h: Reran 'make genstubs'
	
2001-11-20  Miguel Sofer  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* generic/tclExecute.c: missing variable declaration under
	TCL_COMPILE_DEBUG. 

2001-11-20  Miguel Sofer  <[e-mail]>

	* generic/tclExecute.c:
	* generic/tclProc.c: restoring the computations of iPtr->numLevels
	to the original logic (previous to buggy modifs on 2001-11-16).

2001-11-20  Jeff Hobbs  <[e-mail]>

	* tools/eolFix.tcl (new-file):
	* unix/Makefile.in: added EOL correction for Windows bat files to
	dist target. [Bug #219409] (davygrvy)

	* unix/tclUnixInit.c (TclpSetInitialEncodings): update of patch
	from 2001-11-16 that uses the old Tcl encoding check mechanism as
	a fallback to the original.  Also added a TCL_DEFAULT_ENCODING
	#define (defaults to iso8859-1).  Tcl will first try setlocale and
	nl_langinfo, and if that fails, guess based on certain LANG|LC_*
	env vars. [Patch #418645]

2001-11-19  David Gravereaux <[e-mail]>

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

2001-11-19  Miguel Sofer  <[e-mail]>

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

2001-11-19  Vince Darley  <[e-mail]>

	* win/tclWinFile.c:
	* win/tclWinFCmd.c:
	* win/tclWin32Dll.c:
	* doc/file.n:
	* tests/winFCmd.test: improved speed of file normalization
	for Win95/98, and clarified docs on differences in file
	normalization between NT/2000 and the older operating systems.
	Added test to ensure normalization is correct.
	
2001-11-19  Miguel Sofer  <[e-mail]>

	* 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  <[e-mail]>

	* 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.
