ChangeLog.2000   [plain text]

2000-12-14  Don Porter  <>

	* 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  <>

	* 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  <>

	* 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  <>

	* 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  <>

	* 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  <>

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

2000-12-07  jeff hobbs  <>

	* 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  <>

	* 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  <>

	* 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,
	* 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  <>

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

	* 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  <>

	* 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
 	  <>. 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  <>

	* 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  <>

	* 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

	* 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

2000-11-16  Andreas Kupries  <>

	* 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  <>

	* unix/ 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  <>

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

2000-11-15  Donal K. Fellows  <>

	* 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  <>

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

2000-11-03  Jeff Hobbs  <>

	8.4a2 RELEASE

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

	* tools/ 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  <>

	* 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  <>

	* 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 in the future will require the corresponding
	configure script to also be re-autoconf'ed and checked in.

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

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

2000-11-01  Jeff Hobbs  <>

	* 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  <>

	* win/
	* win/
	* win/
	* 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  <>

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

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

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

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

2000-10-27  Jeff Hobbs  <>

	* unix/
	* 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  <>

	* 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 <>

	* 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  <>

	* 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,

2000-10-20  Jeff Hobbs  <>

	* 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  <>

	* 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  <>

	* 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  <>

	* 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

2000-09-29  Jennifer Hom  <>

	* library/tcltest1.0/tcltest2.tcl:
	* tests/tcltest2.test:
	* doc/tcltest2.n: Modified the new form of the test command to
	accept both attribute-value pairs and command line options.
	Updated the tests and the documentation for this new format.
	Also changed the option names for the test command.

2000-09-29  Jeff Hobbs  <>

	* win/tclWinSerial.c (SerialGetOptionProc): corrected reporting of
	space parity on Windows (Eason) [Bug 6057].

	* win/ commented use of TESTFLAGS
	* unix/ added TESTFLAGS to test target to
	conform with Windows makefile and TEA style.

	* tests/stack.test: prevented possible crash on systems with low
	default stacksize (Tru64, AIX) in infinite recursion test.  A
	solution to check remaining stack space in the core is best, but
	hard to do in a cross-platform manner.

	* generic/tclIOGT.c (FLUSH_DELAY): renamed DELAY define to
	FLUSH_DELAY to avoid defn conflict using Tru64's cc.

2000-09-28  Jeff Hobbs  <>

	* tools/ added tclPlatDecls.h and tkPlatDecls.h to the
	Windows .exe install.

	* tests/fCmd.test (fCmd-6.20): corrected test to remove
	c:/tcl8975@ after creating it.

	* tests/fileName.test: cleaned up the testing of glob patterns for
	c:/globTest (Windows) to directly create/remove directory.

2000-09-27  Jeff Hobbs  <>

	* generic/tcl.decls:
	* generic/tclIO.c: updated Tcl_IsChannelShared,
	Tcl_IsChannelRegistered, Tcl_CutChannel, Tcl_SpliceChannel,
	Tcl_IsChannelExisting, and Tcl_ClearChannelHandlers to conform to
	the new stacked channel implementation.  Their stub slots were
	also moved to give preference to the new 8.3.2 stub functions.
	This will cause an incompatability with 8.4a1 only.
	(StopCopy): fixed a bug introduced by a partial fix in 8.3.2 that
	didn't set nonBlocking correctly when resetting the flags for the
	write side.  [Bug: 6261]

	* doc/ChnlStack.3:
	* doc/CrtChannel.3:
	* generic/tcl.decls:

	* win/tclWinChan.c:
	* win/tclWinConsole.c:
	* win/tclWinPipe.c:
	* win/tclWinSerial.c:
	* win/tclWinSock.c: Up-port of changes made in 8.3.2 to 8.4a2 code
	base.  Most of these changes relate to the rewrite of the stacked
	channel implementation, with a few config related fixes.

	Following is an asynchronous include of the applicable ChangeLog
	entries from 8.3.2.

	** START OF ASYNCHRONOUS UP-PORT LOG (8.3.2 -> 8.4a2) **

2000-08-07  Jeff Hobbs  <>

	* doc/ChnlStack.3:
	* doc/CrtChannel.3: updated the docs to be aware of the
	TCL_CHANNEL_VERSION_2 style of Tcl channels.

	* generic/tclIO.c (Tcl_CreateChannel): added assertion to verify
	that the new channel versioning will be binary compatible with
	older channel drivers.

2000-08-05  Jeff Hobbs  <>

	* generic/tclIOGT.c (TclChannelTransform): fixed segfault that
	would occur when transforming a channel with a proc that did not
	yet exist. (Kupries)

	* generic/tclTest.c (TestChannelCmd): added some lint init'ing of
	statePtr and chan vars.

2000-07-26  Jeff Hobbs  <>

	* merged core-8-3-1-io-rewrite back into core-8-3-1-branch.
	The core-8-3-1-io-rewrite branch should now be considered defunct.

	* generic/tclStubInit.c:
	* generic/tclDecls.h:
	* generic/tcl.decls:
	* generic/tcl.h:
	* generic/tclIO.c: moved the Tcl_Channel* macros from tcl.h to
	tclIO.c and made them proper stubbed functions.  These are:
	Tcl_ChannelName, Tcl_ChannelVersion, Tcl_ChannelBlockModeProc,
	Tcl_ChannelCloseProc, Tcl_ChannelClose2Proc, Tcl_ChannelInputProc,
	Tcl_ChannelOutputProc, Tcl_ChannelSeekProc, Tcl_ChannelSetOptionProc,
	Tcl_ChannelGetOptionProc, Tcl_ChannelWatchProc,
	Tcl_ChannelGetHandleProc, Tcl_ChannelFlushProc,
	and Tcl_ChannelHandlerProc.  These should be used to access the
	Tcl_ChannelType structure instead of direct pointer dereferencing.

	* tests/iogt.test: added RCS string, marked tests 2.* to be
	unixOnly due to underlying system differences.

2000-07-25 Andreas Kupries <>

	* tests/iogt.test: (line 866f) New tests iogt-6.[01], highlighting
 	  buffering trouble when stacking and unstacking transformations.
	  iogt-6.0 is solved, see the changes below. iogt-6.1 remains, for
 	  now, due to the perceived complexity of solutions.

	* generic/tclIO.h: (line 139f) struct Channel, added a buffer
	  queue, to hold data pushed back when stacking a transformation.

	* generic/tclIO.c:
	  (line 91f, line 7434f) New internal function 'CopyBuffer'.
	  Derived from 'CopyAndTranslateBuffer', with translation
	  (line 1025f, line 1212f): Initialization of new queue.
	  (line 1164f, Tcl_StackChannel): Pushback of input queue.
	  (line 1293f, Tcl_UnstackChannel): Discard input and pushback.
	  (line 3748f, Tcl_ReadRaw): Modified to use data in the push back
	  area before going to the driver. Uses 'CopyBuffer', s.a.
	  (line 4702f, GetInput): Modified to use data in the push back
	  area before going to the driver.
 	  (line 4867f, Tcl_Seek): Modified to take pushback of the topmost
	  channel in a stack into account.
	  (line 5620f, Tcl_InputBuffered): See above. Added
	  'Tcl_ChannelBuffered'. Analogue to 'Tcl_InputBuffered' but for
	  the buffer area in the channel.

	* generic/tcl.decls: New public API 'Tcl_ChannelBuffered'. S.a.

2000-07-17  Jeff Hobbs  <>

	* unix/
	* win/
	* win/ added tclIOGT.c to objects list to compile.

	* generic/tclStubInit.c:
	* generic/tclIntDecls.h:
	* generic/tclInt.decls: commented out internal decls for
	TclTestChannelCmd and TclTestChannelEventCmd as they were moved to
	tclTest.c.  Added new decls for TclChannelEventScriptInvoker and

	* generic/tclIO.c (CloseChannel): stopped masking out of the
	TCL_READABLE|TCL_WRITABLE bits from the state flags in
	CloseChannel, instead adding extra intelligence to
	CheckChannelErrors with a new CHANNEL_RAW_MODE bit for special
	behavior when called from Raw channel APIs.

2000-07-13  Jeff Hobbs  <>

	* generic/tclIO.c (StackSetBlockMode): moved set of chanPtr
	outside of blockModeProc check to avoid infinite loop when
	blockModeProc was NULL (Kupries).  updated TransformSeekProc to
	not call Tcl_Seek directly (Kupries).

	* win/tclWinChan.c: updated fileChannelType to v2 channel struct
	* win/tclWinConsole.c: updated consoleChannelType to v2 channel struct
	* win/tclWinPipe.c: updated pipeChannelType to v2 channel struct
	* win/tclWinSerial.c: updated serialChannelType to v2 channel struct
	* win/tclWinSock.c: updated tcpChannelType to v2 channel struct

2000-07-11  Brent Welch	<>

	* win/ (TCL_LIBS): Cleaned up unix-specific
	autoconf variables.

2000-07-11  Jeff Hobbs  <>

	* tests/iogt.test: made tests [345].0 not run by default as they
	were failing in the new design, but I'm not convinced that the
	returned result isn't correct.

	* generic/tclDecls.h:
	* generic/tclStubInit.c:
	* generic/tcl.decls: added Tcl_GetTopChannel C API that returns
	the current top channel of a channel stack.  Tcl_GetChannel was
	changed earlier to return the bottommost channel of a stack
	because that is the one that is guaranteed to stay around the
	longest, and this was needed to compensate for certain
	operations that want to look at the state of the main channel.
	Most channel APIs already compensate for grabbing the top, so it
	shouldn't be needed often.

	* generic/tclIO.c (Tcl_StackChannel, Tcl_UnstackChannel): Added
	flushing of buffers (Kupries), removed use of DownChannel macro,
	added Tcl_GetTopChannel public API to get to the top channel of
	the channel stack (necessary for TLS).  Rewrote Tcl_NotifyChannel
	for new channel design (Kupries).  Did some code cleanup in the
	transform code.  tclIO.c must still be broken into bits (separate
	out test code and giot code, create tclIO.h).

2000-07-10  Andreas Kupries <>

	* tests/iogt.test: Reverted some earlier changes as a fix by Jeff
	  revived the original and correct behaviour. IOW, the tests showed
	  a genuine error and I didn't see it :(.

	* generic/tclIO.c (Tcl_Read|Write_Raw): Changed to directly use
 	  the drivers and not DoRead|DoWrite. The latter use the buffering
 	  system, encoding and eol-translation and this wreaks havoc with
 	  the data going through the transformations. Both procedures use
 	  CheckForchannelErrors and let it believe that there is no

	trying to reuse the top stack object.
	Extended evalstats output info with Tcl_IsShared stat info.

	* generic/tclInt.h:
	* generic/tclObj.c (Tcl_DbIsShared): added support for checking
	result of Tcl_IsShared in evalstats (TCL_COMPILE_STATS).

	* generic/tclStringObj.c (Tcl_AppendUnicodeToObj): removed dead code.
	(AppendUnicodeToUnicodeRep) removed overallocation by extra

	* Overall changes:
	  (1) Implementation of joinable threads for all platforms.
	  (2) Additional API's for channels. Required to allow the
	  thread extension to move channels between threads.

	* generic/tcl.decls (lines 1360f): Added Tcl_JoinThread,
	  Tcl_IsChannelShared, Tcl_IsChannelRegistered, Tcl_CutChannel,
	  Tcl_SpliceChannel, Tcl_IsChannelExisting and
	  Tcl_ClearChannelHandlers (slots 394 to 400).

	* generic/tclIO.c: Implemented Tcl_IsChannelRegistered,
 	  Tcl_IsChannelShared, Tcl_CutChannel, Tcl_SpliceChannel,
 	  Tcl_IsChannelExisting and Tcl_ClearChannelHandlers.
	  Tcl_CutChannel uses code from CloseChannel. Replaced this code
 	  by a call to Tcl_CutChannel.  Replaced several code fragments
 	  adding channels to the channel list with calls to
 	  Tcl_SpliceChannel. Removed now unused variables from
 	  CloseChannel and Tcl_UnstackChannel.  Tcl_ClearChannelHandlers
 	  uses code from Tcl_Close. Replaced this code by a call to
 	  Tcl_ClearChannelHandlers. Removed now unused variables from
 	  Tcl_Close. Added the subcommands 'cut', 'forgetch', 'splice' and
 	  'isshared' to the test code

	* unix/tclUnixThread.c: Implemented Tcl_JoinThread using the

	* win/tclWinThrd.c: Fixed several small typos in comments.
	  Implemented Tcl_JoinThread using a platform independent
	  emulation layer (see generic/tclThreadJoin.c below). Added
	  'joinLock' to serialize Tcl_CreateThread and TclpExitThread to
	  prevent a race for joinable threads.

	* mac/tclMacThrd.c: Implemented Tcl_JoinThread using a platform
	  independent emulation layer (see generic/tclThreadJoin.c
	  below). Due to the cooperative nature of threading on this
	  platform the race mentioned above is not present.

	* generic/tclThreadJoin.c: New file. Contains a platform
	  independent emulation layer helping in the implementation of
	  joinable threads for the win and mac platforms.

	* generic/tclInt.h: Added declarations for TclJoinThread,
	  TclRememberJoinableThread and TclSignalExitThread. These
	  procedures define the API of the emulation layer for joinable
	  threads (see generic/tclThreadJoin.c above).

	* win/
	* win/ Added generic/tclTheadJoin.o to the rules.

	* mac/: I don't know to which file generic/tclTheadJoin.o has to
	  be added to so that it compiles. Sorry.

	* unix/tclUnixChan.c: #ifdef'd the thread-local list of file
 	  channels as it prevents us from transfering channels. To restore
 	  this we may need an extended interface to drivers in the
 	  future. Target: 9.0. Found while testing the new transfer of
 	  channels. The information in this list for a channel was left
 	  behind and then crashed the system during finalization.

	* generic/tclThreadTest.c: Added -joinable flag to 'testthread
	  create'. Added subcommand 'testthread join'.

	* doc/CrtChannel.3: Added documentation for Tcl_IsChannelRegistered,
 	  Tcl_IsChannelShared, Tcl_CutChannel, Tcl_SpliceChannel,
	  Tcl_IsChannelExisting and Tcl_ClearChannelHandlers.

	These changes make some error handling marginally better for Mac

	* mac/tclMacSock.c (TcpClose): Add timeouts to the close - these
	don't seem to be honored, however.
	Use a separate PB for the release, since an async connect socket
	will still be using the original buffer.
	Make sure TCPRelease returns noErr before freeing the recvBuff.
	If the call returns an error, then the buffer is not right.
	* mac/tclMacSock.c (CreateSocket): Add timeouts to the async
	create. These don't seem to trigger, however.  Sigh...
	* mac/tclMacSock.c (WaitForSocketEvent): If an TCP_ASYNC_CONNECT
	socket errors out, then return EWOULDBLOCK & error out.

	* library/http2.1/http.tcl: Fixed a newly introduced bug where if
	there's a -command callback and something goes wrong, geturl threw
	an exception, called the callback, and unset the token.  I changed
	it so that it will not call the callback when throwing an
	exception (so the caller only finds out about a given error from
	one place).  Also, fixed http::ncode so that it actually gives you
	back the http return code (i.e. 200, 404, etc.) instead of the
	first digit of the version of HTTP being used (i.e. 1).

	The queryprogress callback is called after each block of query
