2000-12-14  Don Porter  <dgp@users.sourceforge.net>

	* 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  <dgp@users.sourceforge.net>

	* 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  <jhobbs@interwoven.com>

	* 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  <jhobbs@interwoven.com>

	* 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  <a.kupries@westend.com>

	* 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  <fellowsd@cs.man.ac.uk>

	* 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  <jhobbs@interwoven.com>

	* 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  <ericm@ajubasolutions.com>

	* 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  <fellowsd@cs.man.ac.uk>

	* 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  <fellowsd@cs.man.ac.uk>

	* 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  <a.kupries@westend.com>

	* 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

 	  <kennykb@crd.ge.com>. 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  <fellowsd@cs.man.ac.uk>

	* 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  <fellowsd@cs.man.ac.uk>

	* 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  <a.kupries@westend.com>

	* 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  <jeff.hobbs@acm.org>

	* 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  <jeff.hobbs@acm.org>

	* 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  <fellowsd@cs.man.ac.uk>

	* 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  <davygrvy@ajubasolutions.com>

	* win/.cvsignore: Removed 'configure' from the glob list now

	  that it's included.

2000-11-03  Jeff Hobbs  <hobbs@ajubasolutions.com>

	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  <davygrvy@ajubasolutions.com>

	* 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  <hobbs@ajubasolutions.com>

	* 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  <hobbs@ajubasolutions.com>

	* 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  <davygrvy@ajubasolutions.com>

	* 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  <hobbs@ajubasolutions.com>

	* 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  <hobbs@ajubasolutions.com>

	* 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  <jenn@ajubasolutions.com>

	* 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 <davygrvy@ajubasolutions.com>

	* 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  <jenn@ajubasolutions.com>

	* 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  <hobbs@ajubasolutions.com>

	* 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  <jenn@ajubasolutions.com>

	* 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  <davygrvy@ajubasolutions.com>

	* 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  <hobbs@ajubasolutions.com>

	* 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  <jenn@ajubasolutions.com>

	* 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  <hobbs@scriptics.com>

	* win/tclWinSerial.c (SerialGetOptionProc): corrected reporting of

	space parity on Windows (Eason) [Bug 6057].

	* win/Makefile.in: commented use of TESTFLAGS

	* unix/Makefile.in: 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  <hobbs@ajubasolutions.com>

	* tools/tcl.wse.in: 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  <hobbs@ajubasolutions.com>

	* 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:

	* generic/tcl.h:

	* generic/tclDecls.h:

	* generic/tclIO.c:

	* generic/tclIO.h:

	* generic/tclIOGT.c:

	* generic/tclInt.decls:

	* generic/tclIntDecls.h:

	* generic/tclStubInit.c:

	* 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  <hobbs@scriptics.com>

	* 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  <hobbs@scriptics.com>

	* 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  <hobbs@scriptics.com>

	* 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 <a.kupries@westend.com>

	* 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

	  removed.

	  (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
