tcl是工具命令语言

2001-12-28  Jeff Hobbs  <[e-mail]>

	* 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 <[e-mail]>

	* 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 <[e-mail]>

	* 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  <[e-mail]>

	* 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 <[e-mail]>

	* 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 <[e-mail]>

	* 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 <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* win/tclWinSerial.c (SerialCheckProc): corrected time
	calculations to be unsigned. (schroedter)

2001-12-18  Mo DeJong  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]> 

	* Applied #219311 on behalf of Rolf Schroedter
	  <[e-mail]> to prevent fcopy on serial
	  ports from flooding the event queue.

2001-12-11  Miguel Sofer  <[e-mail]>

	* doc/CrtInterp.3:
	* generic/tclBasic.c: docs and comments corrections [Bug 493412]
	Bug & patch by Don Porter.  

2001-12-14  Donal K. Fellows  <[e-mail]>

	* 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  <[e-mail]> 

	* 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  <[e-mail]>

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

2001-12-12  Andreas Kupries  <[e-mail]> 

	* generic/tclIO.c (Tcl_GetsObj): Applied patch for bug #491341 as
	  provided by Don Porter <[e-mail]>. Fixes the
	  assumption of having an empty Tcl_Obj to work with.

2001-12-11  Miguel Sofer  <[e-mail]>

	* 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  <[e-mail]> 

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

2001-12-10  Miguel Sofer  <[e-mail]>

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

2001-12-07  Miguel Sofer  <[e-mail]>

	* generic/tclVar.c: 
	* tests/trace.test: restored consistency in refCount accounting by
	array traces [Bug #4484339], submitted by Don Porter.

	* 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  <[e-mail]>

	* 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  <[e-mail]>

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

	Devin Eyre.

2001-12-03  David Gravereaux <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* tests/namespace.test: modified namespace-41.2, added 41.3
	{knownbug} after discussion with Don Porter and Kevin Kenny.

2001-11-29  Miguel Sofer  <[e-mail]>

	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.

	code for Win95/98.

2001-11-27  David Gravereaux <[e-mail]>

	* 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  <[e-mail]>

	* 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 <[e-mail]>

	* generic/tclIntPlatDecls.h: 'make genstubs' after changes
	in 2001-11-23 commit from Daniel Steffen.

2001-11-24  Mo DeJong  <[e-mail]>

	* 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  <[e-mail]>

	* 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 <[e-mail]>

	* unix/Makefile.in:
	* unix/configure.in:
	* unix/install-sh:
	* unix/mkLinks:
	* unix/mkLinks.tcl:

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

2001-11-23  Daniel Steffen <[e-mail]>

	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)
