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 [Bug
        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]. [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. [Patch 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. [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!) [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. [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. [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:
        * generic/tclTest.c:
        * tests/iogt.test:
        * unix/Makefile.in:
        * win/Makefile.in:
        * win/makefile.vc:
        * win/tclConfig.sh.in:
        * 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
        'Tcl_ChannelBuffered'. Analog 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  <hobbs@scriptics.com>

        * unix/Makefile.in:
        * win/Makefile.in:
        * win/makefile.vc: 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
        TclChannelTransform.

        * 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  <hobbs@scriptics.com>

        * generic/tclIO.c (StackSetBlockMode): moved set of chanPtr outside of
        blockModeProc check to avoid infinite loop when blockModeProc was
        NULL. 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 <welch@ajubasolutions.com>

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

2000-07-11  Jeff Hobbs  <hobbs@scriptics.com>

        * 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 <a.kupries@westend.com>

        * 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 background copy in progress or
        else stacked channels could not be used for that.

        * generic/tclIO.c (TclCopyChannel, CopyData): Moved access to the
        topmost channel from the first to the second procedure to make the
        decision about that at the last possible time (Callbacks can change
        the stacking).

        test suite: failures of iogt-[345].0

2000-07-06  Jeff Hobbs  <hobbs@scriptics.com>

        * tests/iogt.test: new tests for stacked channel stuff based off new
        'testchannel transform|unstack' code (Kupries IOGT extension).
        * generic/tcl.decls:
        * generic/tcl.h:
        * generic/tclDecls.h:
        * generic/tclStubsInit.c:
        * generic/tclIO.c: complete rewrite of Tcl Channel code for stacked
        channels. Channels are now designed to work in a more stacked fashion
        with a shared ChannelState data structure.

2000-06-02  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclIO.c (CloseChannel): removed the &ing out of
        (TCL_READABLE|TCL_WRITABLE) from the flags, as CloseChannel does this
        on the next pass through for the top channel, and it appeared to be
        causing hangs by not allowing the final flush.

2000-06-01  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclIO.c (CloseChannel): Rewrote CloseChannel code to unstack
        a channel during the close process. Fixed a refcount bug in
        Tcl_UnstackChannel. [Bug: 5623]
        (CloseChannel): further extended CloseChannel in the stacked case to
        effect certain operations on the next channel that would have been
        done in Tcl_Close.  Also added CHANNEL_CLOSED and removed
        (TCL_READABLE|TCL_WRITABLE) bits from chanPtr->flags. Changed final
        reset of the WatchProc to check the chanDownPtr's (next) interestMask.

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

2000-09-20  Jeff Hobbs  <hobbs@scriptics.com>

        * tests/socket.test: removed doTestsWithRemoteServer constraint from
        socket-12.*. It requires 'exec', not a remote server. Cleaned up some
        coding errors.

2000-09-20  Jennifer Hom  <jenn@ajubasolutions.com>

        * library/tcltest1.0/pkgIndex.tcl: Updated to load tcltest 2.0.
        * library/tcltest1.0/tcltest2.tcl: New version of tcltest.
        Cleanup of command line parsing: allows users to specify command line
        arguments through an environment variable named TCLTEST_OPTIONS [RFE:
        3748], does not respond to incorrect arguments, and forces usage of
        entire flag name when using command line arguments. Defines accessor
        procs for all tcltest variables. Allows users to use 'return' in test
        scripts. Allow users to specify whether test files should be sourced
        or run in a separate process. 'all.tcl' code moved to tcltest package.
        'test' proc modified to use attribute-value pairs. Allow users to
        specify what return codes, output, and errors can be compared and
        whether these values should be compared using regexp, glob, or exact
        matching. makeDirectory & removeDirectory now operate with respect to
        temporaryDirectory [Bug: 6001]. Test results from tests run in slave
        interpreters are now included in test totals [Bug: 1493]. Test files
        that return error values are now reported.
        * tests/all.tcl: Added code to check for the tcltest version loaded;
        modified to figure out which tests to run based on the tcltest version
        loaded.
        * tests/tcltest.test: Modified to explicitly load version 1.0 of
        tcltest.
        * tests/tcltest2.test: New test suite for tcltest; includes all of the
        old tests plus new ones reflecting changes made for version 2.0.
        * tests/cmdAH.test: Added singleTestInterp constraint to cmdAH-31.2;
        this test does not run if tests aren't sourced into a single
        interpreter.
        * tests/socket.test: Fixed two tests that were referencing variables
        outside of scope.

        * tools/tcl.wse.in: Added code to install tcltest2.tcl.

        * doc/tcltest2.n: New documentation for tcltest version 2.0. Removes
        documentation for tcltest namespace variables. Adds documentation for
        new tcltest procs.

        * unix/mkLinks: Added code to link to tcltest2.n.

        * generic/tcl.h: Added comment to modify tcltest2.tcl as well as
        tcltest.tcl for version changes.

2000-09-19  Eric Melski  <ericm@ajubasolutions.com>

        * generic/tclCmdMZ.c (Tcl_RegexpObjCmd): When using -all, all attempts
        after the first to match the regexp against the string should include
        the TCL_REG_NOTBOL flag, to avoid erroneously matching ^ in the middle
        of the string. Added code to set this flag after the first pass
        through the matching loop. [Bug: 6284].

2000-09-19  David Gravereaux  <davygrvy@ajubasolutions.com>

        * doc/Eval.3: Added a note about the script argument to Tcl_Eval()
        should be in UTF-8 or risk implied conversion errors when possible
        combinations of upper ascii can be valid UTF-8 special codes.

2000-09-17  Eric Melski  <ericm@ajubasolutions.com>

        * tests/cmdIL.test: Added a test for fix for [Bug: 6212].

        * generic/tclCmdIL.c (Tcl_LsortObjCmd): Applied patch from [Bug:
        6212], which corrected an error in the handling of the -index option.

2000-09-14  Eric Melski  <ericm@ajubasolutions.com>

        * doc/Alloc.3: Added entries for Tcl_AttemptAlloc, Tcl_AttempRealloc.

        * doc/StringObj.3: Added entry for Tcl_AttemptSetObjLength.

        * generic/tclDecls.h:
        * generic/tclStubInit.c: Regen'ed stubs files from new tcl.decls.

        * generic/tcl.decls: Added stubs for the Tcl_Attempt* memory
        allocators and for Tcl_AttemptSetObjLength.

        * generic/tcl.h: Added #define's for attemptckalloc, attemptckrealloc,
        which map to the Tcl_Attempt* memory allocators.

        * generic/tclCkalloc.c: Added non-panic'ing versions of Tcl_Alloc,
        Tcl_Realloc, etc.; these are called Tcl_AttemptAlloc,
        Tcl_AttemptRealloc, etc. These are used by Tcl_AttemptSetObjLength and
        the string obj append functions.

        * generic/tclStringObj.c: Modified string growth algorithm to use
        doubling algorithm as long as possible, and only fall back when that
        fails. Added Tcl_AttemptSetObjLength, and modified
        AppendUnicodeToUnicodeRep, AppendUtfToUtfRep, and
        Tcl_AppendStringsToObjVA to support this.

2000-09-07  David Gravereaux <davygrvy@ajubasolutions.com>

        * win/.cvsignore: changed the glob patterns a bit to exclude VC++
        project conversion backups.

        * win/tclWinPipe.c: Stage-1 bug fix for TR#2460 "exec leaks memory".
        Added more logic around the close-down of the pipe reader thread so as
        to avoid, at all cost, a TerminateThread. Most cases with exec are
        fixed, but I don't consider 2460 done yet. Closing down the read side
        of a pipe before the child process, doesn't really fit the windows
        model. [BUG: 2460]

2000-09-07  Jeff Hobbs  <hobbs@scriptics.com>

        * doc/trace.n: minor doc cleanup

2000-09-06  André Pönitz <poenitz@htwm.de>

        * doc/*.n: added or changed "SEE ALSO:" section

2000-09-06  Jeff Hobbs  <hobbs@scriptics.com>

        * win/tclWinLoad.c (TclpLoadFile): added special message for
        ERROR_PROC_NOT_FOUND exception in loading a dll.
        * win/tclWinError.c: changed ERROR_PROC_NOT_FOUND to map from ESRCH
        (POSIX: no such process) to EINVAL because there is no good mapping
        for "procedure not found".

        * README:
        * generic/tcl.h:
        * library/tcltest1.0/tcltest.tcl:
        * tools/tcl.wse.in:
        * tools/tcltk-man2html.tcl:
        * unix/configure.in:
        * unix/tcl.spec:
        * win/README.binary:
        * win/configure.in: updated patchlevel to 8.4a2

        * unix/tclUnixPipe.c (TclpCreateProcess): Removed WNOHANG from
        Tcl_WaitPid call in error case of process creation on Unix, as it
        would lead to defunct processes. [Bug: 6148]

        * tests/string.test: extended string repeat tests
        * generic/tclCmdMZ.c (Tcl_StringObjCmd): changed STR_REPEAT to
        preallocate the full space of the final string, avoided repeated
        appends.

        * doc/source.n:
        * doc/Eval.3: added extra note about how to safe use ^Z in code, as it
        is now a cross-platform (was just Windows) EOF char.

2000-09-05  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclHash.c: fixed pedantic warning of incorrectly placed
        #endif

        * generic/tclExecute.c (TclExecuteByteCode): INST_STR_INDEX fixed
        pedantic cast warning.
        Corrected support for building with -DTCL_COMPILE_STATS.
        Added efficiency check of object equality.

2000-08-29  Eric Melski  <ericm@ajubasolutions.com>

        * generic/tclStringObj.c: Applied patch from Gerhard Hintermayer to
        provide a more conservative string growth algorithm for strings larger
        than one megabyte; this allows more efficient use of memory for very
        large strings.

2000-08-25  Eric Melski  <ericm@ajubasolutions.com>

        * tests/trace.test: Extended array tracing tests.

        * doc/trace.n: Clarified information about when array traces will be
        fired.

        * generic/tclVar.c (Tcl_ArrayObjCmd): Corrected call to CallTraces
        (for TCL_TRACE_ARRAY) to only be called when the variable is either an
        array or is undefined, to ensure that array traces do not fire for
        scalar variables.

2000-08-24  Eric Melski  <ericm@ajubasolutions.com>

        * doc/man.macros: Tweaked tab settings for .SO (Standard Options)
        sections, based on suggestion from Peter Spjuth.

2000-08-24  Mo DeJong  <mdejong@redhat.com>

        * unix/README: Update to account for removal of --enable-gcc.
        * unix/configure.in:
        * unix/tcl.m4 (SC_ENABLE_GCC): Remove --enable-gcc option.
        * win/README: Add note about building with Cygwin.
        * win/configure.in:
        * win/tcl.m4 (SC_ENABLE_GCC): Remove --enable-gcc option. Remove quick
        hack that provided cross compile support for windows builds.

2000-08-24  Eric Melski  <ericm@ajubasolutions.com>

        Overall change: Added support for command rename/delete traces and new
        trace syntax, from patch from Vince Darley. Added support for array
        traces for variables. [RFE: 5048, 5967].

        * doc/trace.n: Updated documentation for new syntax; flagged old
        syntax as deprecated; added documentation for command rename/delete
        traces and variable array traces.

        * tests/trace.test: Updated tests for new trace syntax; new tests for
        command rename/delete traces; new tests for array traces.

        * generic/tclVar.c: Support for new trace syntax; support for
        TCL_TRACE_ARRAY.

        * generic/tclStubInit.c:
        * generic/tclDecls.h:
        * generic/tcl.decls: Stub functions for command rename/delete traces.

        * generic/tcl.h:
        * generic/tclInt.h:
        * generic/tclBasic.c: Support for command traces.

        * generic/tclCmdMZ.c (TclTraceVariableObjCmd): Patched to support new
        [trace] syntax:
        trace {add|remove|list} {variable|command} name ops command
        Added support for command traces (rename, delete operations).
        Added support for TCL_TRACE_ARRAY at Tcl level (array operation for
        variable traces).

2000-08-20  Eric Melski  <ericm@ajubasolutions.com>

        * generic/tclVar.c: Added check for non-arrays for [array statistics]
        command (patch from Mark Patton).

2000-08-19  David Gravereaux <davygrvy@ajubasolutions.com>

        * generic/tclPlatDecls.h: without a previous '#include <windows.h>',
        tclPlatDecls.h can't be parsed due to a missing definition of TCHAR.
        Added a check to include it when not defined.

        ***POSSIBLE OBSCURE BUG*** could be caused when the compile flags for
        the core happen to be different than a project who uses these publics
        regarding -D_MBCS and -D_UNICODE. This added check might have to be
        revisited later with a better understanding of the reprocusions. I
        think TCHAR should be replaced with it's expansion.

2000-08-18  David Gravereaux <davygrvy@ajubasolutions.com>

        * win/.cvsignore (added): provides a cleaner build environment with
        graphical CVS clients.

2000-08-15  Eric Melski  <ericm@ajubasolutions.com>

        * library/tcltest1.0/tcltest.tcl: Set debug level in
        tcltest::restoreState to 2, for consistancy with the debug level in
        tcltest::saveState [Bug: 4505].

2000-08-14  Eric Melski  <ericm@ajubasolutions.com>

        * win/makefile.vc:
        * win/Makefile.in:
        * unix/Makefile.in: Added tclPlatDecls.h to the list of installed
        headers, for more complete stubs support. [Bug: 5241].

        * generic/tcl.h: Added #include "tclPlatDecls.h" to get
        platform-specific stubs declarations (Tcl_WinTCharToUtf, etc)
        [Bug: 5241].

        * README: Updated link for instructions on compiling Tcl from sources
        to point to correct location (http://dev.scriptics.com/doc/... instead
        of http://dev.scriptics.com/support/...).

2000-08-11  Eric Melski  <ericm@ajubasolutions.com>

        * generic/tclEnv.c (TclUnsetEnv): Changed declaration of length
        variable from "unsigned int" to "int", to match usage when passed to
        TclpFindVariable [Bug: 6126].

2000-08-10  Eric Melski  <ericm@ajubasolutions.com>

        * library/msgcat1.0/pkgIndex.tcl: Bumped version number to 1.2 [Bug:
        6100].

        * library/msgcat1.0/msgcat.tcl: Removed erroneous [package forget] in
        msgcat namespace initializer. Bumped version number to 1.2 [Bug: 6100]

2000-08-10  David Gravereaux <davygrvy@ajubasolutions.com>

        * generic/tclObj.c: r1.15 accidentally changed a global mutex name
        tclObjMutex to ObjMutex.  Put the correct name back.

2000-08-07  Eric Melski  <ericm@ajubasolutions.com>

        * tests/indexObj.test: Added tests using the [testwrongnumargs]
        command to test Tcl_WrongNumArgs.

        * generic/tclTest.c (TestWrongNumArgsObjCmd): Added test function for
        the Tcl_WrongNumArgs function.

        alerting on all platforms as it was only working on Win before.
        Removed older Win hacks that would end-up waking the wrong notifier in
        the presence of a threaded build. All tests pass as before. New test
        cases will be added soon for the new behavior. [BUG: 5791]

2000-07-25  Eric Melski  <ericm@ajubasolutions.com>

        * generic/tclVar.c (CallTraces): Added check for VAR_TRACE_ACTIVE on
        the array containing the variable before executing traces on that
        array, to conform with normal variable traces and the documentation,
        which states that while executing a trace, other traces on that
        variable are disabled. [Bug: 6049].

        * win/tclWinPipe.c (BuildCommandLine): Added Tcl_DStringFree call to
        prevent potential memory leaks [Bug: 6041].

2000-07-24  Eric Melski  <ericm@ajubasolutions.com>

        * library/package.tcl: Enhanced pkg_compareExtension to handle Unixes
        which tack the version number on to the end of library names (eg,
        foo.so.1.2); such filenames will be correctly matched. (Patch from
        Vince Darley).

        * win/makefile.vc: Applied patch from Don Porter to provide better
        nmake support for NT/Alpha [RFE: 5938].

        * win/tclWinChan.c: Win2K OS bug with GetStdHandle(STD_OUTPUT_HANDLE)
        giving the wrong answer. This made TclpGetDefaultStdChannel grab what
        it thought was a valid native stdout handle. Added a new WriteFile()
        test to make sure it's really valid. This OS bug doesn't affect the
        shells. Only -subsystem:windows (aka WinMain) application that
        dynamically load tclXX.dll [BUG: 5971]

        * library/msgcat1.0/msgcat.tcl:
        * doc/msgcat.n:
        * tests/msgcat.test: Applied patches from Chris Nelson, to provide the
        mcmset function, which allows the translator to set multiple string
        translations in a single function call, rather than requiring many
        calls to mcset. [RFE: 6000, 5993]. In addition, these patches correct
        mcload to use utf-8 encoding on when reading message catalog files,
        and provides for better default behavior for determining the locale on
        a Windows system.

2000-07-17  Mo DeJong  <mdejong@redhat.com>

        * library/msgcat1.0/msgcat.tcl: Applied patches from Laurent Duperval,
        to add mcmax function, which computes the length of the longest of
        several translated strings. Bumped version number to 1.1.

2000-06-27  Eric Melski  <ericm@scriptics.com>

        * tests/stringObj.test: Tweaked tests to avoid hardcoded high-ASCII

        8.4a1 RELEASE

        * generic/tclExecute.c (TclExecuteByteCode INST_STR_CMP): added test
        of iResult return from memcmp, as memcmp isn't required to return only
        -1,0,1.

2000-06-03  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): Corrected caching

        * tests/http.test
        * doc/http.n
        * library/http2.3/http.tcl: Fixed bug 5741, where unsuccessful geturl
        calls sometimes leaked memory and resources (sockets). Also, switched
        around some of the logic so that http::wait never throws an exception.
        This is because in an asynchronous geturl, the command callback will
        probably end up doing all the error handling anyway, and in an
        asynchronous situation, the user expects to check the state when the
        transaction completes, as opposed to being thrown an exception. For
        the http package, this menas the user can check http::status for
        "error" and http::error for the error message after doing the
        http::wait.

2000-05-26  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclCmdMZ.c (Tcl_RegsubObjCmd): reworked to operate in
        Unicode, tweaked for performance.
        (Tcl_StringObjCmd) changed STR_FIRST/STR_LAST error message to
        something more understandable, reworked STR_FIRST, STR_LAST, STR_MAP,
        STR_MATCH, STR_RANGE, STR_REPLACE to operate in Unicode. Removed
        inneffectual STR_RANGE "special" ByteArray support. Optimized STR_MAP
        algorithm, especially optimized for one-pair case. Fixed possible mem
        overrun in STR_INDEX bytearray case.

        * generic/tclCompCmds.c: added byte compiler support for [string
        compare|match|index].
        * generic/tclExecute.c: Changed INST_STR_(N)EQ to return an Int object
        and not bother trying to reuse the top stack object. Added
        INST_STR_CMP, INST_STR_INDEX, INST_STR_MATCH bytecode ops. 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
        sizeof(Tcl_UniChar) multiplier.

        * tests/string.test: added string map tests for the one-pair case,
        corrected tests to reflect improved error messages in first/last.
        Added tests against mem overrun in string index bytearray case.

2000-05-23  Eric Melski  <ericm@scriptics.com>

        those that are not an out-line compiled.

        (TclCompileReturnCmd): Byte-compiled implementation of [return]
        command. Only "simple" returns are byte-compiled; in particular, if
        the -code, -errorinfo or -errorcode flags are used, the command is not
        byte-compiled.

        Tcl_DuplicateObj where code was otherwise duplicated. Made special
        case of inserting one element at the end work again (where index ==
        len).
        (Tcl_LreplaceObjCmd): moved Tcl_DuplicateObj call lower and cleaned
        up use of other arguments.

        * generic/tclObj.c (Tcl_DuplicateObj): simplified code to call
        TclInitStringRep, which the code was just duplicating in part.

        * doc/Utf.3:
        * generic/tclStubInit.c:
        * generic/tcl.decls:
        * generic/tclDecls.h:
        * generic/tclUtf.c: Added new functions Tcl_UniCharNcasecmp and
        Tcl_UniCharCaseMatch (unicode parallel to Tcl_StringCaseMatch)
        * generic/tclUtil.c: rewrote Tcl_StringCaseMatch algorithm for
        optimization and made Tcl_StringMatch just call Tcl_StringCaseMatch
        * tests/string.test: extended string match tests

2000-05-02  Andreas Kupries <a.kupries@westend.com>

        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 (TclTestChannelCmd).

        * unix/tclUnixThread.c: Implemented Tcl_JoinThread using the
        pthread-functionality.

        * 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/Makefile.in:
        * win/makefile.vc: 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.

        * doc/Thread.3: Added documentation for Tcl_JoinThread.

        * tests/thread.test: Added tests for joining of threads.

2000-04-27  Eric Melski  <ericm@scriptics.com>

        * doc/library.n: Added entries for auto_qualify and auto_import
        [Bug: 1271].

        * doc/Init.3: Manual entry for Tcl_Init [Bug: 1820].

        * doc/expr.n: Added documentation for each of the math library
        functions that expr supports [Bug: 1054].

2000-04-26  Eric Melski  <ericm@scriptics.com>

        * doc/memory.n: Man page for Tcl "memory" command, which is created
        when TCL_MEM_DEBUG is defined at compile time.

        * doc/TCL_MEM_DEBUG.3: Man page with overall information about
        TCL_MEM_DEBUG usage.

        * doc/DumpActiveMemory.3: Man page for Tcl_DumpActiveMemory,
        Tcl_InitMemory, and Tcl_ValidateAllMemory [Bug: 1816, 1835].

        * generic/tclCkalloc.c: Fixed some function headers.

        * unix/mkLinks: Regen'd with new mkLinks.tcl.

        * unix/mkLinks.tcl: Fixed indentation, made link setup more
        intelligent (only do one existance test per man page, instead of one
        per function).

        * doc/library.n: Fixed .SH NAME macro to include each function
        documented on the page, so that mkLinks will know about the functions
        listed there, and so that the Windows help file index will get set up
        correctly [Bug: 1898, 5273].

        added write of 'q' into triggerPipe for notifier in threaded case, so
        that Tcl doesn't hang when children are still running [Bug: 4139]

        * unix/tclUnixThrd.c (Tcl_MutexLock): minor comment fixes.

2000-04-23  Jim Ingham  <jingham@cygnus.com>

        These changes make some error handling marginally better for Mac
        sockets. It is still somewhat flakey, however.

        * 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.
        * mac/tclMacSock.c (NotifyRoutine): Added a NotifyRoutine for
        experimenting with MacTCP.

2000-04-22  Jim Ingham <jingham@cygnus.com>

        * library/package.tcl (tclPkgUnknown): Fixed a typo in the Mac package
        search part of tclPkgUnknown.

2000-04-21  Sandeep Tamhankar <sandeep@scriptics.com>

        * 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).

2000-04-21  Brent Welch <welch@scriptics.com>

        * library/http2.1/http.tcl: More thrashing with the "server closes
        without reading post data" scenario. Reverted to the previous filevent
        configuratiuon, which seems to work better with small amounts of post
        data.

2000-04-20  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclAlloc.c: wrapped caddr_t define to not be done on Unix
        * unix/tclUnixPort.h: added Tclp*Alloc defines to allow the use of
        USE_TCLALLOC on Unix. [Bug: 4731]

        * library/reg1.0/pkgIndex.tcl:
        * win/tclWinChan.c:
        * win/tclWinThrd.c: converted CRLF to LF the */tcl.hpj.in files were
        not converted, as it confuses hcw locally. [Bug: 5096]

        * win/Makefile.in: expanded cleanup target for help files

        * doc/Thread.3: minor macro cleanup

        * generic/tclFileName.c (SplitUnixPath): added support for QNX node
        ids.

        mode (default state) after a -async connect succeeds. [Bug: 4388]

        * generic/tclEvent.c (TclInitSubsystems): Moved tclLibraryPath to
        thread-local storage to prevent thread-related race condition.
        [Bug: 5033]
        * unix/tclAppInit.c (main): removed #ifdef TCL_TEST that sets the
        library path as it was unnecessary and conflicts with move of
        tclLibraryPath to thread-local storage.

        * unix/tcl.m4 (SC_ENABLE_THREADS): enhanced the detection of

        * generic/tcl.h: Fixed Tcl_CreateThread declaration.

        initialization to work with either testthread or the thread extension
        * unix/tclUnixThrd.c: Fixed compiler warning when compiling with
        -DTCL_THREADS

2000-04-10  Eric Melski  <ericm@scriptics.com>

        * win/tclWinPipe.c (TclpCreateTempFile): Added conversion of contents
        string from UTF to native encoding [Bug: 4030].

        * tests/regexp.test: Added tests for infinite looping in [regexp
        -all].

        * generic/tclCmdMZ.c: Fixed infinite loop bug with [regexp -all]
        [Bug: 4981].

        * tests/*.test: Changed all occurances of "namespace import
        ::tcltest" to "namespace import -force ::tcltest" [Bug: 3948].

2000-04-09  Brent Welch <welch@scriptics.com>

        * lib/httpd2.1/http.tcl: Worked on the "server closes before reading
        post data" case, which unfortunately causes different error cases on
        Solaris, which can read the reply, and Linux and Windows, which cannot
        read anything. This is all in the loop-back case - client and server
        on the same host. Also unified the error handling so the "ioerror"
        status goes away and errors are reflected in a more uniform way.
        Updated the man page to document the behavior.

2000-04-09  Jeff Hobbs  <hobbs@scriptics.com>

        * tests/reg.test (matchexpected): corrected tests to use tcltest
        constraint types to skip certain tests.

        * generic/tclBasic.c (Tcl_SetCommandInfo): comment fix

        * unix/tclUnixThrd.c (Tcl_CreateThread): moved TCL_THREADS ifdef
        inside of func as it is declared for non-threads builds as well. In
        the non-threads case, it always returns TCL_ERROR (couldn't create
        thread).

2000-04-08  Andreas Kupries <a.kupries@westend.com>

        * Overall change: Definition of a public API for the creation of
        new threads.

        * generic/tclInt.h (line 1802f): Removed the definition of
        'TclpThreadCreate'. (line 793f) Removed the definition of
        'Tcl_ThreadCreateProc'.

        * generic/tcl.h (line 388f): Readded the definition of
        'Tcl_ThreadCreateProc'. Added Win32 stuff send in by David Graveraux
        <davygrvy@bigfoot.com> to that too (__stdcall, ...). Added macros for
        the default stacksize and allowed flags.

        * generic/tcl.decls (line 1356f): Added definition of
        'Tcl_CreateThread', slot 393 of the stub table. Two new arguments in
        the public API, for stacksize and flags.

        * win/tclWinThrd.c:
        * mac/tclMacThrd.c: Renamed TclpThreadCreate to Tcl_CreateThread,
        added handling of the stacksize. Flags are currently ignored.

        * unix/tclUnixThrd.c: See above, but handles joinable flag. Ignores
        the specified stacksize if the macro HAVE_PTHREAD_ATTR_SETSTACKSIZE is
        not defined.

        * generic/tclThreadTest.c (line 363): See below.

        * unix/tclUnixNotfy.c (line 210): Adapted to the changes above. Uses
        default stacksize and no flags now.

        * unic/tcl.m4 (line 382f): Added a check for
        'pthread_attr_setstacksize' to detect platforms not implementing this
        feature of pthreads. If it is implemented, configure will define the
        macro HAVE_PTHREAD_ATTR_SETSTACKSIZE (See unix/tclUnixThrd.c too).

        * doc/Thread.3: Added Tcl_CreateThread and its arguments to the list
        of described functions. Removed stuff about not providing a public
        C-API for thread-creation.

2000-04-07  Jeff Hobbs  <hobbs@scriptics.com>

        * doc/binary.n: clarified docs on sign extension in binary scan [Bug:
        3466]

        * library/tcltest1.0/tcltest.tcl (initConstraints): removed win32s
        references (no longer supported)

        * tests/fCmd.test: marked test 8.1 knownBug because it is dangerous on
        poorly configured systems [Bug: 3881] and added 8.2 to keep essence of
        8.1 tested.

2000-04-05  Andreas Kupries <a.kupries@westend.com>

        * generic/tclIO.c (Tcl_UnstackChannel, line 1831): Forcing interest
        mask to the correct value after an unstack and re-initialization of
        the notifier via the watchProc. Without this the first fileevent after
        an unstack will come through and be processed, but no more. [Bug: ??].

2000-03-04  Brent Welch  <welch@scriptics.com>

        * {win,unix}/Makefile.in: added dependency of tclStubInit.c on
        tcl.decls and tclInt.decls
        * generic/tclThread.c: Tweak so this compiles w/out TCL_THREADS
        * generic/{tcl.decls,tclStubInit.c}:  Just touched the tcl.decls and
        regenerated the tclStubInit.c file

2000-03-29  Sandeep Tamhankar <sandeep@scriptics.com>

        * library/http2.1/http.tcl: For the -querychannel option, fconfigure
        the socket to be binary so that we don't translate anything while
        reading the data. This is because we determine the content length of
        the data on the channel by using seek (to the end of the file) and
        tell on the file handle, and we need the content-length to match the
        amount of data actually sent, and translation can affect the number of
        bytes posted.

2000-04-03  Andreas Kupries <a.kupries@westend.com>

        * Overall change: Definition of public API's for the finalization of
        conditions and mutexes. [Bug: 4199].

        * generic/tclInt.h: Removed definitions of TclFinalizeMutex and
        TclFinalizeCondition.

        * generic/tcl.decls: Added declarations of Tcl_MutexFinalize and
        Tcl_ConditionFinalize.

        * generic/tclThread.c: Renamed TclFinalizeMutex to Tcl_MutexFinalize.
        Renamed TclFinalizeCondition to Tcl_ConditionFinalize.

        * generic/tclNotify.c: Changed usage of TclFinalizeMutex to
        Tcl_MutexFinalize.

        * unix/tclUnixNotfy.c:
        * generic/tclThreadTest.c: Changed usages of TclFinalizeCondition to
        Tcl_ConditionFinalize.

        * generic/tcl.h: Added empty macros for Tcl_MutexFinalize and
        Tcl_ConditionFinalize, to be used when the core is compiled without
        threads.

        * doc/Thread.3: Added description the new API's.

2000-04-03  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclCmdIL.c (InfoVarsCmd): checked for non-NULL procPtr to
        prevent itcl info override crash [Bug: 4064]

        * tests/foreach.test:
        * tests/namespace.test:
        * tests/var.test: Added lsorts to avoid random sorted return
        problems. [Bug: 2682]

        * tests/fileName.test: fixed 14.1 test fragility [Bug: 1482]

        * tools/man2help2.tcl: fixed winhelp cross-linking error [Bug: 4156]
        improved translation to winhelp [Bug: 3679]

        * unix/Makefile.in (MAN_INSTALL_DIR): patch to accept --mandir
        correctly [Bug: 4085]

        * unix/dltest/pkg[a-e].c: Cleaned up test packages [Bug: 2293]

2000-04-03  Eric Melski  <ericm@scriptics.com>

        * unix/tclUnixFCmd.c (SetGroupAttribute):
        * unix/tclUnixFCmd.c (SetOwnerAttribute): Added (uid_t) and (gid_t)
        casts to avoid compiler warnings.

2000-03-31  Eric Melski  <ericm@scriptics.com>

        * generic/tclGet.c (Tcl_GetDouble): Added additional conditions to
        error test (previously only errno was checked, but the return value of
        strtod() should be checked as well). [Bug: 4118]

        * tests/exec.test: Added test for proper conversion of UTF data when
        used with "<< $dataWithUTF" on exec's.

        * unix/tclUnixPipe.c (TclpCreateTempFile): Added
        Tcl_UtfToExternalDString call, so that if there is UTF content in the
        string it will be properly converted to the system encoding before
        being written [Bug: 4030].
        (TclpCreateTempFile): Added a check on the return value of tmpnam;
        some systems (Linux, for example) will start to return NULL after
        tmpnam has been called TMP_MAX times; not checking for this can have
        bad results (overwriting temp files, core dumps, etc.)

2000-03-30  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclBasic.c (Tcl_DeleteCommandFromToken): Added comments
        noting the need to pair ckalloc with ckfree. [Bug: 4262]

        * generic/tclInt.decls:
        * generic/tclIntPlatDecls.h:
        * generic/tclStubInit.c:
        * win/tclWin32Dll.c: removed TclWinSynchSpawn (vestige of Win32s
        support).

        * win/tclWinReg.c: made use of TclWinGetPlatformId instead of getting
        info again

        * win/tclWinPort.h:
        * win/Makefile.in:
        * win/configure.in:
        * win/tcl.m4: Added support for gcc/mingw on Windows [Bug: 4234]

2000-03-29  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclCompile.c (TclCleanupByteCode): made ByteCode cleanup
        more aware of TCL_BYTECODE_PRECOMPILED flagged structs (gen'd by
        tbcload), to correctly clean them up.

        * generic/tclClock.c (FormatClock): moved check for empty format
        earlier, commented 0 result return value

2000-03-29  Sandeep Tamhankar <sandeep@scriptics.com>

        * library/http2.1/http.tcl: Removed an unnecessary fileevent statement
        from the error processing part of the Write method. Also, fixed two
        potential memory leaks in wait and reset, in which the state array
        wasn't being unset before throwing an exception. Prior to this
        version, Brent checked in a fix to catch a fileevent statement that
        was sometimes causing a stack trace when geturl was called with
        -timeout. I believe Brent's fix is necessary because TLS closes bad
        sockets for secure connections, and the fileevent was trying to act on
        a socket that no longer existed.

2000-03-27  Jeff Hobbs  <hobbs@scriptics.com>

        * tests/httpd: removed unnecessary 'puts stderr "Post Dispatch"'

        * tests/namespace.test:
        * generic/tclNamesp.c (Tcl_Export): added a uniq'ing test to the
        export list so only one instance of each export pattern would exist in
        the list.

        * generic/tclExecute.c (TclExecuteByteCode): optimized case for the
        empty string in ==/!= comparisons

2000-03-27  Eric Melski  <ericm@scriptics.com>

        * unix/tclUnixChan.c: Added (off_t) type casts in lseek() call [Bug:
        4409].

        * unix/tclLoadAout.c:
        * unix/tclUnixPipe.c: Added (off_t) type casts in lseek() calls [Bug:
        4410].

2000-03-22  Sandeep Tamhankar <sandeep@scriptics.com>

        * library/http2.1/http.tcl: Fixed a bug where string query data that
        was bigger than queryblocksize would get duplicate characters at block
        boundaries.

2000-03-22  Sandeep Tamhankar <sandeep@scriptics.com>

        * library/http2.1/http.tcl: Fixed bug 4463, where we were getting a
        stack trace if we tried to publish a project to a good host but a port
        where there was no server listening.  It turned out the problem was a
        stray fileevent that needed to be cleared.  Also, fixed a bug where
        http::code could stack trace if called on a bad token (one which
        didn't represent a successful geturl) by adding an http element to the
        state array in geturl.

2000-03-21  Eric Melski  <ericm@scriptics.com>

        * tests/clock.test: Modified some tests that were not robust with
        respect to the time zone in which they were run and were thus failing.

        * doc/clock.n: Clarified meaning of -gmt with respect to -base when
        used with [clock scan] (-gmt does not affect the interpretation of
        -base).

2000-03-19  Sandeep Tamhankar <sandeep@scriptics.com>

        * library/http2.1/http.tcl: geturl used to throw an exception when the
        connection failed; I accidentally returned a token with the error
        info, breaking backwards compatibility. I changed it back to throwing
        an exception, but unsetting the state array first (thus still
        eliminating the original memory leak problem).

2000-03-19  Sandeep Tamhankar <sandeep@scriptics.com>

        * library/http2.1/http.tcl: Added -querychannel option and altered
        some of Brent's modifications to allow asynchronous posts (via
        -command). Also modified -queryprogress so that it calls the query
        callback as <callback> <token> <total size> <current size> to be
        consistent with -progress. Added -queryblocksize option with default
        8192 bytes for post blocksize. Fixed a bunch of potential memory leaks
        for the case when geturl receives bad args or can't open a socket,
        etc. Overall, the package really rocks now.

        * doc/http.n: Added -queryblocksize, -querychannel, and
        -queryprogress. Also, changed the description of -blocksize, which
        states that the -progress callback will be called for each block, to
        now qualify that with an "if -progress is specified".

        * tests/http.test: Added a querychannel test for synchronous and
        asynchronous posts, altered the queryprogress test such that the
        callback conforms to the -progress format. Also, had to use the
        -queryblocksize option to do the post 16K at a time to match Brent's
        expected results (and to test that -queryblocksize works).

2000-03-15  Brent Welch <welch@scriptics.com>

        * library/http2.1/http.tcl: Added -queryprogress callback to
        http::geturl and also changed it so that writing the post data is
        event driven if the queryprogress callback or a timeout is given.
        This allows a timeout to occur when writing lots of post data. The
        queryprogress callback is called after each block of query data is
        posted. It has the same signature as the -progress callback.

2000-03-06  Eric Melski  <ericm@scriptics.com>

        * library/package.tcl: Applied patch from Bug: 2570; rather than
        setting geometry of slave interp to 0x0 when Tk was loaded, it now
        does "wm withdraw .". Both remove the main window from the display,
        but the former caused some internal structures to get initialized to
        zero, which caused crashes with some extensions.

2000-03-02  Jeff Hobbs  <hobbs@scriptics.com>

        * library/package.tcl (tclPkgUnknown): extended to allow recognizes
        changes in the auto_path while sourcing in other pkgIndex.tcl files

        * doc/FindExec.3: fixed doc for declaration of Tcl_FindExecutable
        [Bug: 4275]

        * generic/tclFileName.c (Tcl_TranslateFileName): Applied patch from
        Newman to significantly speedup file split/join on Windows (replaces
        regexp with custom parser). [Bug: 2867]

        * win/README.binary: change mailing lists from @consortium.org to
        @scriptics.com [Bug: 4173]

2000-02-28  Eric Melski  <ericm@scriptics.com>

        * tests/clock.test: Added test for ISO bases < 100000

        * generic/tclDate.c: (generated on Solaris)
        * generic/tclGetDate.y: Changed condition for deciding if a number is
        an ISO 8601 base from number >= 100000 to numberOfDigits >= 6.
        Previously it would fail to recognize 000000 as an ISO base.

2000-02-14  Eric Melski  <ericm@scriptics.com>

        * unix/Makefile.in: Added rpm target to generate Tcl binary RPM.

        * unix/tcl.spec: RPM specification file for a Tcl binary RPM for
        Linux.

2000-02-10  Jeff Hobbs  <hobbs@scriptics.com>

        8.3.0 RELEASE

        * changes: updated for 8.3.0 release

        * doc/load.n: added notes about dll load errors on Windows

        * unix/README:
        * unix/Makefile.in (dist): removed porting.notes and porting.old from
        distribution and CVS.  The information was very outdated. Now refer to
        http://dev.scriptics.com/services/support/platforms.html

        * tests/unixInit.test: fixed japanese LANG encoding test [Bug: 3549]

        * unix/configure.in:
        * unix/tcl.m4: correct CFLAG_WARNING setting, fixed gcc config for
        AIX, added -export-dynamic to LDFLAGS for FreeBSD-3+ [Bug: 2998]

        * win/tclWinLoad.c (TclpLoadFile): improved error message for load
        failures, could perhaps be even more intelligent.

2000-02-09  Jim Ingham   <jingham@cygnus.com>

        * mac/tclMacSock.c: Don't panic when you get an error closing an async
        socket. This doesn't seem to hurt anything, and we return the error so
        the caller can do the right thing.

        New Files:
        * mac/MW_TclHeader.h:
        * mac/MW_TclTestHeader.h:
        * mac/MW_TclTestHeader.pch:
        * mac/MW_TclAppleScriptHeader.h: More convenient to use .h prefix
        files in the preference panels...

        The above are curtesy of Daniel Steffen (steffen@math.mq.edu.au)

2000-02-08  Eric Melski  <ericm@scriptics.com>

        * tests/clock.test: Added tests for "next monthname" constructs.
        * generic/tclDate.c:
        * generic/tclGetDate.y (Message): Added a grammar rule for "next
        monthname" so that we can handle "next january" and similar constructs
        (bug #4146).

2000-02-08  Jeff Hobbs  <hobbs@scriptics.com>

        * README:

        list to allow dirnames with spaces

        * unix/tcl.m4: changed all -fpic to -fPIC

        * generic/tclDecls.h:
        * generic/tcl.decls: change Tcl_GetOpenFile to use decl of 'int
        forWriting' instead of 'int write' to avoid shadowing [Bug: 4121]

        * tests/httpold.test: changed test script to source in the httpd
        server procs from httpd instead of having its own set.

        * tests/httpd: improved query support in test httpd to handle fix in
        http.tcl. [Bug: 4089 change 2000-02-01]

        * unix/README: fixed notes about --enable-shared and add note about
        --disable-shared.

2000-02-07  Eric Melski  <ericm@scriptics.com>

        * tests/package.test:
        * library/tclIndex:
        * library/package.tcl: Renamed ::package namespace to ::pkg.

2000-02-03  Eric Melski <ericm@scriptics.com>

        * doc/Package.n:
        * doc/packagens.n: Renamed Package.n -> packagens.n because Windows
        can't deal with case-sensitive names.

2000-02-02  Jeff Hobbs  <hobbs@scriptics.com>

        * tests/regexp.test: added tests for -all and -inline switches
        * doc/regexp.n: added docs for -all and -inline switches
        * generic/tclCmdMZ.c (Tcl_RegexpObjCmd): added extra comments for new
        -all and -inline switches to regexp command

2000-02-01  Eric Melski  <ericm@scriptics.com>

        * library/init.tcl: Applied patch from rfe 1734 regarding auto_load
        errors not setting error message and errorInfo properly.

2000-02-01  Jeff Hobbs  <hobbs@scriptics.com>

        * win/Makefile.in (install-*): reduced verbosity of install

        * generic/tclFileName.c (Tcl_JoinPath): improved support for special
        QNX node id prefixes in pathnames [Bug: 4053]

        * library/http1.0/http.tcl:
        * library/http2.1/http.tcl: The query data POSTed was newline
        terminated when it shouldn't be altered [Bug: 4089]

2000-01-31  Eric Melski  <ericm@scriptics.com>

        * tests/package.test:
        * library/tclIndex:
        * library/package.tcl: Added ::package namespace and ::package::create
        function.

        * library/init.tcl: Fixed problem with auto_load and determining if
        commands were loaded.

        * library/auto.tcl: "Fixed" issues with $ in files to be auto indexed.

        * doc/Package.n: New man page for package::create function.

        * doc/pkgMkIndex.n: Added additional information.

        * doc/library.n: Added additional qualification regarding auto_mkindex.

2000-01-28  Eric Melski  <ericm@scriptics.com>

        * tests/pkg/magicchar2.tcl:
        * tests/autoMkindex.test: Test for auto loader fix (bug #2480).

        * library/init.tcl: auto_load was using [info commands $name] to
        determine if a given command was available; if the command name had *
        or [] it, this would fail because info commands uses glob-style
        matching. This is fixed. (Bug #2480).

        * tests/pkg/spacename.tcl:
        * tests/pkgMkIndex.test: Tests for fix for bug #2360.

        * library/package.tcl: Fixed to extract only the first element of the
        list returned by auto_qualify (bug #2360).

        * tests/pkg/magicchar.tcl:
        * tests/autoMkindex.test: Test for fix for bug #2611.

        * library/auto.tcl: Fixed the regular expression that performs $
        escaping before sourcing a file to index. It was erroneously adding \
        escapes even to $'s that were already escaped, effectively
        "un-escaping" those $'s. (bug #2611).

2000-01-27  Eric Melski  <ericm@scriptics.com>

        * tests/autoMkindex.test:
        * library/auto.tcl: Applied patch (with slight modification) from bug
        #2701: auto_mkIndex uses platform dependent file paths. Added test for
        fix.

2000-01-27  Jennifer Hom  <jenn@scriptics.com>

        * library/tcltest1.0/tcltest.tcl: Changed NormalizePath to
        normalizePath and exported it as a public proc. This proc creates an
        absolute path given the name of the variable containing the path to
        modify. The path is modified in place.
        * library/tcltest1.0/pkgIndex.tcl: Added normalizePath.
        * tests/all.tcl: Changed code to use normalizePath.

2000-01-27  Eric Melski  <ericm@scriptics.com>

        * tests/pkg/samename.tcl: test file for bug #1983

        * tests/pkgMkIndex.test:
        * doc/pkgMkIndex.n:
        * library/package.tcl: Per rfe #4097, optimized creation of direct
        load packages to bypass computing the list of commands added by the
        new package. Also made direct loading the default, and added a -lazy
        option.
        Fixed bug #1983, dealing with pkg_mkIndex incorrectly handling
        situations with two procs by the same name but in different namespaces
        (ie, foo::baz and bar::baz).

2000-01-26  Eric Melski  <ericm@scriptics.com>

        * generic/tclNamesp.c: Undid fix for #956, which broke backwards
        compatibility.

        * doc/variable.n:
        * doc/trace.n:
        * doc/namespace.n:
        * doc/info.n: Added further information about differences between
        "namespace which" and "info exists".

        * doc/SetErrno.3: Added descriptions of ErrnoId() and ErrnoMsg()
        functions.

2000-01-25  Jeff Hobbs  <hobbs@scriptics.com>

        * unix/tcl.m4: modified EXTRA_CFLAGS to add -DHAVE_TZSET for OSF1-V*
        and ULTRIX-4.* when not using gcc. Also added higher min stack size
        for OSF1-V* when building with threads. [Bug: 4063]

        * generic/tclClock.c (FormatClock): inlined resultPtr, as it
        conflicted with var creation for HAVE_TZSET #def [Bug: 4063]

        * generic/tclCmdIL.c (Tcl_LsortObjCmd): fixed potential leak when
        calling lsort -command with bad command [Bug: 4067]

        * generic/tclFileName.c (Tcl_JoinPath): added support for special QNX
        node id prefixes in pathnames [Bug: 4053]

        * doc/ListObj.3: clarified Tcl_ListObjGetElements docs [Bug: 4080]

        * doc/glob.n: clarified Mac path separator determination docs.

        * win/makefile.vc: added some support for building helpfile on Windows

2000-01-23  Jeff Hobbs  <hobbs@scriptics.com>

        * library/init.tcl (auto_execok): added 'start' to list of recognized
        built-in commands for COMSPEC on NT. [Bug: 2858]

        * unix/tclUnixPort.h: moved include of <utime.h> lower since some
        systems (UTS) require sys/types.h to be included first [Bug: 4031]

        * unix/tclUnixChan.c (CreateSocketAddress): changed comparison with -1
        to 0xFFFFFFFF, to ensure 32 bit comparison even on 64 bit systems.
        [Bug: 3878]

        * generic/tclFileName.c: improved guessing of path separator for the
        Mac. (Darley)

        * generic/tclInt.h:
        * generic/tcl.decls: moved Tcl_ProcObjCmd to stubs table [Bug: 3827]
        and removed 'register' from stub definition of
        Tcl_AppendUnicodeToObj [Bug: 4038]

2000-01-21  Eric Melski  <ericm@scriptics.com>

        * unix/mkLinks:
        * doc/GetHostName.3: Man page for Tcl_GetHostName (bug #1817).

        * doc/lreplace.n: Corrected man page with respect to treatment of
        empty lists, and "prettied up" the page. (bug #1705).

2000-01-20  Eric Melski  <ericm@scriptics.com>

        * tests/namespace.test: Added test for undefined variables with
        namespace which (bug #956).

        * generic/tclNamesp.c: Added check for undefined variables in
        NamespaceWhichCmd (bug #956).

        * tests/var.test: Added tests for corrected variable behavior (bug
        #981).

        * doc/upvar.n: Expanded explanation of upvar behavior with respect to
        variable traces. (bugs 3917 1433 2110).

        * generic/tclVar.c: Changed behavior of variable command when name
        refers to an element in an array (ie, "variable foo(x)") to always
        return an error, regardless of existance of that element in the array
        (now behavior is consistant with docs too) (bug #981).

2000-01-20  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclCmdIL.c (InfoBodyCmd): made [info body] return a string
        if the body has been bytecompiled.
        * generic/tclBasic.c (Tcl_EvalObjEx): added pedantic check for
        originating proc body of bytecompiled code, #def'd out as the change
        for [info body] should make it unnecessary

        * unix/tclUnixNotfy.c (Tcl_InitNotifier): added cast for tsdPtr

        * tests/set.test: added test for complex array elem name compiling
        * generic/tclCompCmds.c (TclCompileSetCmd): Fixed parsing of array
        elements during compiling, and slightly optimised same [Bug: 3889]

        * doc/tclvars.n: added definitions for tcl_(non)wordchars

        * doc/vwait.n: added notes about requirement for vwait var being
        globally scoped [Bug: 3329]

        * library/word.tcl: changed tcl_(non)wordchars settings to use new
        unicode regexp char class escapes instead of char sequences

2000-01-14  Eric Melski  <ericm@scriptics.com>

        * tests/var.test: Added a test for the array multiple delete
        protection in Tcl_UnsetVar2.

        * generic/tclVar.c: Added protection in Tcl_UnsetVar2 against attempts
        to multiply delete arrays when unsetting them (bug #3453). This could
        happen if there was an unset trace on an array element and the trace
        proc made a global or upvar link to the array, and then the array was
        unset at the global level. See the bug reference for more information.

        * unix/tclUnixTime.c: New clock format format.

        * compat/strftime.c: New clock format format.

        * generic/tclGetDate.y: New clock scan format.

        * unix/configure.in:
        * unix/tcl.m4:
        * win/README.binary:
        * win/configure.in: updated to patchlevel 8.3b2

2000-01-13  Eric Melski  <ericm@scriptics.com>

        * tests/cmdIL.test: Added tests for lsort -dictionary with characters
        that occur between Z and a in ASCII.

        * generic/tclCmdIL.c: Modified DictionaryCompare function (used by
        lsort -dictionary) to do upper/lower case equivalency before doing
        character comparisons, instead of after. This fixes bug #1357, in
        which lsort -dictionary [list ` AA c CC] and lsort -dictionary [list
        AA c ` CC] gave different (and both wrong) results.

2000-01-12  Eric Melski  <ericm@scriptics.com>

        * generic/tclClock.c: fixed support for 64bit handling of clock values
        [Bug: 1806]

        * generic/tclThreadTest.c: upped a buffer size to hold double

        * generic/tclCmdIL.c: fixed 'info procs ::namesp::*' behavior (Dejong)

        * generic/tclNamesp.c: made imported commands also import their
        compile proc [Bug: 2100]

        * tests/expr.test:
        * unix/Makefile.in:
        * unix/configure.in:
        * unix/tcl.m4: recognize strtod bug on Tru64 v5.0 [Bug: 3378] and
        added tests to prevent unnecessary chmod +x in sources while
        installing, as well as more intelligent setsockopt/gethostbyname
        checks [Bug: 3366, 3389]

        * unix/tclUnixThrd.c: added compile time support (through use of the
        TCL_THREAD_STACK_MIN define) for increasing the default stack size for
        a thread. [Bug: 3797, 1966]

2000-01-11  Eric Melski  <ericm@scriptics.com>

        * generic/tclGetDate.y: Added comments for the Convert function. Added
        a fix for daylight savings time handling for relative time spans of
        days, weeks or fortnights. (bug 3441, 3868).

        * generic/tclDate.c: Fixed compiler warning issues.

2000-01-10  Jeff Hobbs  <hobbs@scriptics.com>

        * compat/waitpid.c: use pid_t type instead of int [Bug: 3999]

        * tests/utf.test: fixed test that allowed \8 as octal value
        * generic/tclUtf.c: changed Tcl_UtfBackslash to not allow non-octal
        digits (8,9) in \ooo substs. [Bug: 3975]

2000-01-10  Eric Melski  <ericm@scriptics.com>

        * generic/tclGetDate.y: Added rules for ISO 8601 formats (BUG #847):
        CCYY-MM-DD
        CCYYMMDD
        YY-MM-DD
        YYMMDD
        CCYYMMDDTHHMMSS
        CCYYMMDD HHMMSS
        CCYYMMDDTHH:MM:SS
        Fixed "clock scan <number>" to scan the number as an hour for the
        current day, rather than a minute after 00:00 for the current day
        (bug #2732).

2000-01-07  Eric Melski  <ericm@scriptics.com>

        * generic/tclClock.c: Changed switch in Tcl_ClockObjCmd to use
        enumerated values instead of constants. (ie, COMMAND_SCAN instead of
        3).
