tcl是工具命令语言

2000-12-14  Don Porter  <[e-mail]>

	* generic/tclExecute.c:
	* tests/expr-old.test:  Re-wrote Tcl's [expr rand()] and
	[expr srand($seed)] implementations, fixing a range error
	on some 64-bit platforms.  Added tests that detect the bug.
	The rewrite changes the seed -> sequence map on 64-bit
	platforms, only for seed >= 2^31, a slight incompatibility.
	[Bug 121072, Patch 102781]

2000-12-10  Don Porter  <[e-mail]>

	* library/init.tcl:
	* library/msgcat/msgcat.tcl:
	* library/msgcat/pkgIndex.tcl:
	* library/opt/optparse.tcl:
	* library/opt/pkgIndex.tcl: Where [uplevel] is used in a proc
	to evaluate a Tcl built-in command in the caller's context,
	the built-in commands are now fully namespace-qualified.  This
	prevents problems when the caller context is in a namespace where
	the built-in command name has been used by a command in the
	namespace.  (For example, [::ns::set] might be called instead
	of the intended [::set]).  [Bug #119422, Patch #102545]

2000-12-09  jeff hobbs  <[e-mail]>

	* win/tclWinTime.c (CalibrationThread): added lint return value to
	prevent compiler warning.  [Bug #125005]

	* docs/scan.n:
	* tests/scan.test:
	* generic/tclScan.c (Tcl_ScanObjCmd): changed %o and %x to use
	strtoul instead of strtol to correctly preserve scan<>format
	conversion of large integers.  [Patch #102663, Bug #124600]

	* generic/tclExecute.c (TclExecuteByteCode): Commited patch fixing
	handling of {!<boolean>} in expressions. [Patch #102702]

2000-12-08  jeff hobbs  <[e-mail]>

	* library/init.tcl: Added support for PATHEXT variable in
	auto_execok, recognizing the proper set of executable extensions
	on Windows.  [Patch #102719]

2000-12-08  Andreas Kupries  <[e-mail]>

	* generic/tclEncoding.c (LoadTableEncoding): Changed dangerous
	  code to something less critical. This fixes bug 119417, part A
	  without affecting the speed when loading encodings.

2000-12-08  Donal K. Fellows  <[e-mail]>

	* doc/open.n: Added xref to fconfigure and advice on the opening
	  of binary files.  Should help prevent a recurrence of bugs like
	  #124558

2000-12-07  jeff hobbs  <[e-mail]>

	* generic/tcl.h: added note about need to updated
	library/dde/pkgIndex.tcl with minor version increment.

	* library/dde/pkgIndex.tcl: updated to use 84 version to reflect
	the makefile.  Should probably be updated to use its real version
	at some point. [Patch #102560, Bug #119421]

2000-12-06  eric melski  <[e-mail]>

	* generic/tcl.h (attemptckalloc): Fixed typo for #define of
	attemptckalloc (was defined to Tcl_AttempDbCkalloc, should have
	been Tcl_AttemptDbCkalloc). [Bug: 124384]

	* generic/tclCkalloc.c: Added
	TCL_MEM_DEBUG versions of Tcl_AttemptDbCkrealloc and
	Tcl_AttemptDbCkalloc. [Bug: 124384].

2000-11-24  Donal K. Fellows  <[e-mail]>

	* generic/tclExecute.c (TclExecuteByteCode): Logical negation "!"
	  can now handle string booleans, provided those values are placed
	  in variables.

	* tests/expr.test (expr-13.17): Check that [expr {!$var}] can
	  negate the string-versions of booleans "yes", "false", etc.

	* library/tcltest/tcltest.tcl (getMatchingFiles,
	  getMatchingDirectories):
	* tools/man2html.tcl (doDir): 
	* tools/man2help.tcl (doDir): 
	* library/package.tcl (tclPkgUnknown,tclMacPkgSearch): 
	* library/safe.tcl (AddSubDirs): [glob] uses -directory instead of
	  unsafe [file join] to fix Bug #123313

	* generic/tclIndexObj.c:
	* generic/tclTestObj.c (TestindexobjCmd): Changed internal
	  representation of index objects to fix Bug #119082; fix
	  shouldn't be visible to outside world...

	* generic/tclTest.c (TestGetIndexFromObjStructObjCmd): 
	* tests/indexObj.test: (indexObj-6.*) Added to test for presence
	  of Bug #119082.

2000-11-23  Donal K. Fellows  <[e-mail]>

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Fixed memory leak from Bug
	  #119398

	* library/init.tcl (unknown): Added specific level parameters to
	  all uplevel invokations to boost performance; didn't dare touch
	  the "namespace inscope" stuff though, since it looks sensitive
	  to me!  Should fix Bug #123217, though testing is tricky...

2000-11-21  Andreas Kupries  <[e-mail]>

	* All of the changes below are described in TIP #7 ~ Specification
 	  and result from the application of the patch contained
 	  therein. Creator of the patch is Kevin Kenny
 	  <[e-mail]>. The patch used here is actually a bit
 	  different. Two MS specific constant values (format FOOui64) were
 	  replaced with a more portable formatting of the values and an
 	  additional cast to LONGLONG. My cross-compiling gcc was unable to
	  process the original form. The SF Id of the patch is 102459.

	* tclWinTime.c: Add to the static data a set of variables that
 	  manage the phase-locked techniques, including a
 	  ''CRITICAL_SECTION'' to guard them so that multi-threaded code
 	  is stable.

	* tclWinTime.c: Modify ''TclpGetSeconds'' to call ''TclpGetTime''
 	  and return the 'seconds' portion of the result.  This change is
 	  necessary to make sure that the two times are consistent near
 	  the rollover from one second to another.

	* tclWinTime.c: Modify ''TclpGetClicks'' to use TclpGetTime to
 	  determine the click count as a number of microseconds.

	* tclWinTime.c: Modify ''TclpGetTime'' to return the time as
 	  M*Q+B, where Q is the result of ''QueryPerformanceCounter'', and
 	  M and B are variables maintained by the phase-locked loop to
 	  keep the result as close as possible to the system clock.  The
 	  ''TclpGetTime'' call will also launch the phase-lock management
 	  in a separate thread the first time that it is invoked.  If the
 	  performance counter is unavailable, or if its frequency is not
 	  one of the two common 8254-compatible rates, then
 	  ''TclpGetTime'' will return the result of ''ftime'' as it does
 	  in Tcl 8.3.2.

	* tclWinTime.c: Add the clock calibration procedure.  The
 	  calibration is somewhat complex; to save space, the reader is
 	  referred to the reference implementation for the details of how
 	  the time base and frequency are maintained.

	* tclWinNotify.c: Modify ''Tcl_Sleep'' to test that the process
 	  has, in fact, slept for the requisite time by calling
 	  ''TclpGetTime'' and comparing with the desired time.  Otherwise,
 	  roundoff errors may cause the process to awaken early.

	* tclWinTest.c: Add a ''testwinclock'' command.  This command
 	  returns a four element list comprising the seconds and
 	  microseconds portions of the system clock and the seconds and
 	  microseconds portions of the Tcl clock.

	* winTime.test: Add to the test suite a test that makes sure that
 	  the Tcl clock stays within 1.1 ms of the system clock over the
 	  duration of the test.

2000-11-21  Donal K. Fellows  <[e-mail]>

	* doc/global.n: 
	* doc/upvar.n: 
	* doc/variable.n: Improved documentation to mention that variables
	  so created are listed in [info locals] and added a few more
	  cross-links between these commands.  Fixes bug #119387

2000-11-17  Donal K. Fellows  <[e-mail]>

	* tests/safe.test: (safe-4.3):
	* generic/tclVar.c (TclLookupVar): Changed again.  Now passes all
	  the tests, though one needed modifying since it required the
	  wrong answer.  (Why on earth do we have inline modification of
	  argument strings?  This sort of thing is horrendous to debug and
	  doesn't work well in a multithreaded environment!)  Fixes bug
	  119192.

	* tests/var.test: (var-1.19) If my attempts to fix the problem
	  aren't right yet, my attempts to describe it look pretty good to
	  me...

2000-11-16  Andreas Kupries  <[e-mail]>

	* win/tclWinPort.h (line 69): Changed reference to winsock2.h into
 	  winsock.h. This was a leftover from a foray into using winsock
 	  version 2 (History lesson from Scott Redman and Jeff
 	  Hobbs). This code was no problem when compiling Tcl itself, but
 	  could trip extensions. Fixes bug 122568.

2000-11-15  jeff hobbs  <[e-mail]>

	* unix/Makefile.in: removed bp.c references (hasn't existed in a
	  long time).  Corrected 'make dist' to make dist with unversioned
	  library directories (same as out of cvs), so make install works
	  correctly with either source tree.

2000-11-15  jeff hobbs  <[e-mail]>

	* generic/tclVar.c (TclLookupVar): reverted fix below as it broke
	  all other array unset error reporting.  Bug-119192 is still
	  open.

2000-11-15  Donal K. Fellows  <[e-mail]>

	* generic/tclVar.c (TclLookupVar): Changed references to part2 to
	  use elName instead in various error message generating spots, so
	  as to fix Bug-119192.

2000-11-03  David Gravereaux  <[e-mail]>

	* win/.cvsignore: Removed 'configure' from the glob list now
	  that it's included.

2000-11-03  Jeff Hobbs  <[e-mail]>

	8.4a2 RELEASE

	* unix/Makefile.in (install-libraries, dist): 
	* win/makefile.vc (install-libraries):
	* win/Makefile.in (install-libraries): updated to install
	unversioned library directories into versioned directories.

	* tools/tcl.wse.in: updated for unversioning of library dirs

	* unix/mkLinks: updated mkLinks with latest doc updates

	* doc/Tcl_Main.3: added docs for Tcl_SetMainLoop

	* generic/tclStubInit.c:
	* generic/tclDecls.h:
	* generic/tcl.decls: added Tcl_SetMainLoop proc that allows people
	to set a main loop that will run for tclsh.
	* generic/tcl.h: added Tcl_MainLoopProc typedef
	* generic/tclMain.c (Tcl_SetMainLoop, StdinProc, Prompt): new
	StdinProc and Prompt static procs and Tcl_SetMainLoop stubs proc.
	The first two handle a fileevent based prompt (taken from
	tkMain.c).  Tcl_SetMainLoop enables the interactive setting of a
	main loop procedure.  This enables Tk to be a loadable package.

2000-11-02  David Gravereaux  <[e-mail]>

	* generic/tclEvent.c: tclLibraryPath Tcl_Obj didn't have a way
	to share its data among threads.  This caused Tcl_Init() to
	always fail in threads.  Added a way to pass the data around
	with a global char*.  [BUG: 5301]

2000-11-02  Jeff Hobbs  <[e-mail]>

	* unix/configure:
	* unix/dltest/configure:
	* win/configure:
	* tools/configure: checked in configure scripts so people doing
	CVS checkouts aren't required to have autoconf.  Changes to
	configure.in in the future will require the corresponding
	configure script to also be re-autoconf'ed and checked in.

	* win/makefile.vc:
	* win/tcl.m4: makefile fixes for Win64 support

	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): minor cast
	changes.

2000-11-01  Jeff Hobbs  <[e-mail]>

	* unix/tcl.m4: removed use of -lbsd and -ldl for AIX-5.

	* tests/subst.test: added tests for non-zero return code handling
	by subst.
	* generic/tclParse.c (Tcl_EvalEx): corrected handling of non-zero,
	non-error return code cases for subst. [BUG: 119829]

	* generic/tclVar.c (TclVarTraceExists): Corrected excessive mem
	use when info exists was called on a non-existent array element.
	[BUG: 119213, 119336]

2000-10-30  David Gravereaux  <[e-mail]>

	* win/configure.in:
	* win/Makefile.in:
	* win/makefile.vc:
	* win/tcl.rc:
	* win/tclsh.rc: Added logic to derive filenames better in the resource
	scripts based on compile options.

2000-10-30  Jeff Hobbs  <[e-mail]>

	* unix/tclUnixInit.c: added default encoding map from
	"ja_JP.eucJP" to "euc-jp". (takahashi)

	* tests/clock.test: corrected clock-2.* test numbering

	* unix/configure.in (SC_TCL_LINK_LIBS): removed code that was
	commented out (it had been moved to tcl.m4's SC_TCL_LINK_LIBS
	already).

	* unix/tcl.m4: consolidated gettimeofday check for AIX.

2000-10-27  Jeff Hobbs  <[e-mail]>

	* unix/configure.in:
	* unix/tcl.m4: added support for AIX-5.

	* generic/tclIO.c (Tcl_NotifyChannel): removed #ifdef around code
	for old channel structures, placed preserve/release around statePtr
	* generic/tclIO.c (CloseChannel): the statePtr for a channel was
	not being freed when the last channel in a stack was freed,
	causing a mem leak.

	* unix/tclUnixChan.c: updated channel types to strict
	TCL_CHANNEL_VERSION_2 style to avoid compiler warnings.  They work
	either way, but this avoids compiler warnings (that worries people).

2000-10-27  Jennifer Hom  <[e-mail]>

	* library/tcltest1.0/tcltest.tcl: Removed a cd into the test
	directory in runAllTests that screwed up the temporary directory
	setting, effectively preventing users from running tests on
	multiple platforms at the same time.

2000-10-26  David Gravereaux <[e-mail]>

	* win/tclWinFile.c (TclpMatchFilesTypes): NULL was being set to
	"attr" which was a DWORD.  Changed NULL to zero because a 'void *'
	can't be set to a DWORD to avoid the compiler warning.

2000-10-24  Jennifer Hom  <[e-mail]>

	* tests/all.tcl: Removed support for tcltest 1.0.
	
	* tests/tcltest.test:
	* library/tcltest1.0/tcltest.tcl:
	* library/tcltest1.0/pkgIndex.tcl:
	* docs/tcltest.n: Moved tcltest2 code so that it's the standard
	version of tcltest.  Removed all tcltest2 files
	(tests/tcltest2.test, library/tcltest1.0/tcltest2.tcl,
	docs/tcltest2.n). 

2000-10-20  Jeff Hobbs  <[e-mail]>

	* win/tclWinFile.c (TclpMatchFilesTypes): made the stat call only
	occur when necessary (for 'glob' command).  Significantly speeds
	up glob command from 8.3. [BUG: 6216]

2000-10-19  Jennifer Hom  <[e-mail]>

	* library/tcltest1.0/tcltest2.tcl:
	* tests/tcltest2
	* doc/tcltest2.n: Code and documentation cleanup.  Modified
	-verbose to take list of keywords as well as string of letters.
	Removed Tcl version information from tcltest. Removed
	tcltest::grep from tcltest package. Added optional 3rd directory
	argument to  makeFile/makeDirectory and removeFile/removeDirectory.

	* tests/basic.test: Changed references to tcltest::tclVersion to
	hardcoded numbers.
	* generic/tcl.h: Changed reference to tcltest2.tcl and tcltest.tcl
	in comments to tests/basic.test.

2000-10-06  David Gravereaux  <[e-mail]>

	* win/tclWinChan.c: moved Win2K bug case test with GetStdHandle()
	from TclpGetDefaultStdChannel into Tcl_MakeFileChannel to enable
	a more general method in detecting invalid OS handles rather than
	just a specific known case. [BUG: 5971]

2000-10-06  Jeff Hobbs  <[e-mail]>

	* tests/cmdAH.test: extra tests for 'file channels' that include
	multiple interpreter tests and channel sharing
	* generic/tclIO.c (Tcl_GetChannelNamesEx): corrected function (and
	consequently 'file channels') to return channels that are actually
	registered for this specific interp, rather than this thread.

	* doc/CrtChannel.3: fixed spelling mistakes
