        ExitThread to _endthreadex

1999-12-12  Jeff Hobbs  <hobbs@scriptics.com>

        * doc/glob.n:
        * tests/fileName.test:
        * generic/tclInt.decls:
        * generic/tclInt.h:
        * generic/tclIntDecls.h:
        * generic/tclStubInit.c:
        * generic/tclEncoding.c:
        * generic/tclFileName.c:
        * mac/tclMacFile.c:
        * unix/tclUnixFile.c:
        * win/tclWinFile.c: enhanced the glob command with the new options
        -types -path -directory and -join.  Deprecated TclpMatchFiles with
        TclpMatchFilesTypes, extended TclGlob and TclDoGlob and added
        GlobTypeData structure. [Bug: 2363]

1999-12-10  Jeff Hobbs  <hobbs@scriptics.com>

        * tests/var.test:
        * generic/tclCompile.c: fixed problem where setting to {} array
        would intermittently not work. (Fontaine) [Bug: 3339]

        * generic/tclCmdMZ.c:
        * generic/tclExecute.c: optimized INST_TRY_CVT_TO_NUMERIC to
        recognize boolean objects. (Spjuth) [Bug: 2815]

        * tests/info.test:
        * tests/parseOld.test:
        * generic/tclCmdAH.c:
        * generic/tclProc.c: changed Tcl_UplevelObjCmd (uplevel) and
        Tcl_EvalObjCmd (eval) to use TCL_EVAL_DIRECT in the single arg
        case as well, to take advantage of potential pure list input
        optimization.  This means that it won't get byte compiled though,
        which should be acceptable.
        * generic/tclBasic.c: made Tcl_EvalObjEx pure list object aware in
        the TCL_EVAL_DIRECT case for efficiency.
        * generic/tclUtil.c: made Tcl_ConcatObj pure list object aware,
        and return a list object in that case [Bug: 2098 2257]

        * generic/tclMain.c: changed Tcl_Main to not constantly reuse the
        commandPtr object (interactive case) as it could be shared. (Fellows)

        * unix/configure.in:
        * unix/tcl.m4:
        * unix/tclUnixPipe.c: removed checking for compatible vfork
        function and use of the vfork function.  Modern VM systems rarely
        suffer any performance degradation when fork is used, and it
        solves multiple problems with vfork.  Users that still want vfork
        can add -Dfork=vfork to the compile flags. [Bug: 942 2228 1312]

1999-12-09  Jeff Hobbs  <hobbs@scriptics.com>

        * win/aclocal.m4: made it just include tcl.m4

        * doc/exec.n:
        * doc/open.n:
        * win/tclWin32Dll.c:
        * win/tclWinChan.c:
        * win/tclWinFCmd.c:
        * win/tclWinInit.c:
        * win/tclWinPipe.c:
        * win/tclWinSock.c: removed all code that supported Win32s.  It
        was no longer officially supported, and likely didn't work anyway.
        * win/makefile.vc: removed 16 bit stuff, cleaned up.

        * win/tcl16.rc:
        * win/tclWin16.c:
        * win/winDumpExts.c: these files have been removed from the
        source tree (no longer necessary to build)

1999-12-07  Jeff Hobbs  <hobbs@scriptics.com>

        * tests/io.test: removed 'knownBug' tests that were for
        unsupported0, which is now fcopy (that already has tests)

        * mac/tclMacPort.h: added utime.h include

        * generic/tclDate.c:
        * unix/Makefile.in: fixed make gendate to swap const with CONST
        so it uses the Tcl defined CONST type [Bug: 3521]

        * generic/tclIO.c: removed panic that could occur in FlushChannel
        when a "blocking" channel would receive EAGAIN, instead treating
        it the same as non-blocking. [Bug: 3773]

        * generic/tclUtil.c: fixed Tcl_ScanCountedElement to not step
        beyond the end of the counted string [Bug: 3336]

1999-12-03  Jeff Hobbs  <hobbs@scriptics.com>

        * doc/load.n: added note about NT's buggy handling of './' with
        LoadLibrary

        * library/http2.1/http.tcl: fixed error handling in http::Event
        [Bug: 3752]

        * tests/env.test: removed knownBug limitation from working test
        * tests/all.tcl: ensured that ::tcltest::testsDirectory would be
        set to an absolute path

        * tests/expr-old.test:
        * tests/parseExpr.test:
        * tests/string.test:
        * generic/tclGet.c:
        * generic/tclInt.h:
        * generic/tclObj.c:
        * generic/tclParseExpr.c:
        * generic/tclUtil.c:
        * generic/tclExecute.c: added TclCheckBadOctal routine to enhance
        error message checking for when users use invalid octal numbers
        (like 08), as well as replumbed the Expr*Funcs with a new
        VerifyExprObjType to simplify type handling. [Bug: 2467]

        * tests/expr.test:
        * generic/tclCompile.c: fixed 'bad code length' error for
        'expr + {[incr]}' case, with new test case [Bug: 3736]
        and seg fault on 'expr + {[error]}' (different cause) that
        was caused by a correct optimization that didn't correctly
        track how it was modifying the source string in the opt.
        The optimization was removed, which means that:
                expr 1 + {[string length abc]}
        will be not be compiled inline as before, but this should be
        written:
                expr {1 + [string length abc]}
        which will be compiled inline for speed.  This prevents
                expr 1 + {[mindless error]}
        from seg faulting, and only affects optimizations for
        degenerate cases [Bug: 3737]

1999-12-01  Scott Redman <redman@scriptics.com>

        * generic/tcl.decls :
        * generic/tclMain.c :
        * unix/tclAppInit.c: 
        * win/tclAppInit.c: Added two new internal functions,
        TclSetStartupScriptFileName() and TclGetStartupScriptFileName()
        and added hooks into the main() code for supporting TclPro and
        other "big" shells more easily without requiring a copy of the
        main() code.
        
        * generic/tclEncoding.c:
        * generic/tclEvent.c:  Moved encoding-related startup code from
        tclEvent.c into the more appropriate tclEncoding.c.
        
1999-11-30  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclIO.c: fix from Kupries for Tcl_UnstackChannel that
        correctly handles resetting translation and encoding.

        * generic/tclLoad.c: #def'd out the unloading of DLLs at finalize
        time for Unix in TclFinalizeLoad. [Bug: 2560 3373]  Should be
        parametrized to allow for user to specify unload or not.

        * win/tclWinTime.c: fixed handling of %Z on NT for time zones
        that don't have DST.

1999-11-29  Jeff Hobbs  <hobbs@scriptics.com>

        * library/dde1.1/pkgIndex.tcl:
        * library/reg1.0/pkgIndex.tcl: added supported for debugged
        versions of the libraries

        * unix/tclUnixPipe.c: fixed PipeBlockModeProc to properly set
        isNonBlocking flag on pipe. [Bug: 1356 710]
        removed spurious fcntl call from PipeBlockModeProc

        * tests/scan.test:
        * generic/tclScan.c: fixed scan where %[..] didn't match anything
        and added test case [Bug: 3700]

1999-11-24  Jeff Hobbs  <hobbs@scriptics.com>

        * doc/open.n:
        * win/tclWinSerial.c: adopted patch from Schroedter to handle
        fconfigure $sock -lasterror on Windows. [RFE: 3368]

        * generic/tclCmdIL.c: made SORTMODE_INTEGER work with Longs
        [Bug: 3652]

1999-11-23  Scott Stanton  <stanton@scriptics.com>

        * library/tcltest1.0/tcltest.tcl: Fixed bug where tcltest output
        went to stdout instead of the specified output file in some
        cases.

1999-11-19  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclProc.c: backed out change from 1999-11-18 as it
        could affect return string from upvar as well.

        * tools/tcl.wse.in: added tcltest1.0 library to distribution list

        * doc/http.n:
        * library/http2.1/http.tcl:

        * unix/tcl.m4: added defined for _THREAD_SAFE in --enable-threads
        case; added check for pthread_mutex_init in libc; in AIX case,
        with --enable-threads ${CC}_r is used; fixed flags when using gcc
        on SCO

        * generic/tclProc.c: corrected error reporting for default case
        at the global level for uplevel command.

        * generic/tclIOSock.c: changed int to size_t type for len
        in TclSockMinimumBuffers.

        * generic/tclCkalloc.c: fixed Tcl_DbCkfree to return a value
        on NULL input. [Bug: 3400]

        * generic/tclStringObj.c: fixed support for passing in negative
        length to Tcl_SetUnicodeObj, et al handling routines. [Bug: 3380]

        * doc/scan.n:
        * tests/scan.test:
        * generic/tclScan.c: finished support for inline scan by
        supporting XPG identifiers.

        * doc/http.n:
        * library/http2.1/http.tcl: added register and unregister
        commands to http:: package (better support for tls/SSL),
        as well as -type argument to http::geturl. [RFE: 2617]

        * generic/tclBasic.c: removed extra decr of numLevels in
        Tcl_EvalObjEx that could cause seg fault. (mjansen@wendt.de)

        * generic/tclEvent.c: fixed possible lack of MutexUnlock in
        Tcl_DeleteExitHandler [Bug: 3545]

        * unix/tcl.m4: Added better pthreads library check and inclusion
        of _THREAD_SAFE in --enable-threads case

        * library/http2.1/http.tcl: Correctly fixed the -timeout
        problem mentioned in the 10-29 change.  Also added error
        handling for failed writes on the socket during the protocol.

1999-11-09  Jeff Hobbs  <hobbs@scriptics.com>

        * doc/open.n: corrected docs for 'a' open mode.

        * generic/tclIOUtil.c: changed Tcl_Alloc to ckalloc

        * generic/tclInt.h:
        * generic/tclObj.c: rolled back changes from 1999-10-29
        Purify noted new leaks with that code

        * generic/tclParse.c: added code in Tcl_ParseBraces to test for
        possible unbalanced open brace in a comment

        * library/init.tcl: removed the installed binary directory from
        the auto_path variable

        * tools/tcl.wse.in: updated to 8.3a1, fixed install of twind.tcl
        and koi8-r.enc files

        * unix/tcl.m4: added recognition of pthreads library for AIX

1999-10-29  Brent Welch <welch@scriptics.com>
        * generic/tclInt.h: Modified the TclNewObj and TclDecrRefCount
        in two ways.  First, in the case of TCL_THREADS, we do not use
        the special Tcl_Obj allocator because that is a source of 
        lock contention.  Second, general code cleanup to eliminate
        duplicated code. In particular, TclDecrRefCount now uses
        TclFreeObj instead of duplicating that code, so it is now
        identical to Tcl_DecrRefCount.

        * generic/tclObj.c: Changed Tcl_NewObj so it uses the
        TclNewObj macro instead of duplicating the code.  Adjusted
        TclFreeObj so it understands the TCL_THREADS case described
        above.

        * library/http2.1/http.tcl: Fixed a bug in the handling of
        the state(status) variable when the -timeout flag is specified.
        Previously it was possible to leave the status undefined
        instead of empty, which caused errors in http::status

1999-10-28  Jeff Hobbs  <hobbs@scriptics.com>

        * unix/aclocal.m4: made it just include tcl.m4

        * library/tcltest1.0/tcltest.tcl: updated makeFile to return
        full pathname of file created

        * generic/tclStringObj.c: fixed Tcl_AppendStringsToObjVA so it only
        iterates once over the va_list (avoiding a memcpy of it,
        which is not portable).

        * generic/tclEnv.c: fixed possible ABR error in environ array

        * tests/scan.test:
        * generic/tclScan.c: added support for use of inline scan,
        XPG3 currently not included

        * tests/incr.test:
        * tests/set.test:
        * generic/tclCompCmds.c: fixed improper bytecode handling of
        'eval {set array($unknownvar) 5}' (also for incr) [Bug: 3184]

        * win/tclWinTest.c: added testvolumetype command, as atime is
        completely ignored for Windows FAT file systems
        * win/tclWinPort.h: added sys/utime.h to includes
        * unix/tclUnixPort.h: added utime.h to includes
        * doc/file.n:
        * tests/cmdAH.test:
        * generic/tclCmdAH.c: added time arguments to atime and mtime
        file command methods (support 'touch' functionality)

1999-10-20  Jeff Hobbs  <hobbs@scriptics.com>

        * unix/tclUnixNotfy.c: fixed event/io threading problems by
        making triggerPipe non-blocking [Bug: 2792]

        * library/tcltest1.0/tcltest.tcl:
        * generic/tclThreadTest.c: fixed mem leaks in threads

        * generic/tclResult.c: fixed Tcl_AppendResultVA so it only
        iterates once over the va_list (avoiding a memcpy of it,
        which is not portable).

        * generic/regc_color.c: fixed mem leak and assertion, from HS

        * generic/tclCompile.c: removed savedChar trick that appeared to
        be causing a segv when the literal table was released

        * tests/string.test:
        * generic/tclCmdMZ.c: fixed [string index] to return ByteArrayObj
        when indexing into one (test case string-5.16) [Bug: 2871]

        * library/http2.1/http.tcl: protected gets with catch [Bug: 2665]

1999-10-19  Jennifer Hom  <jenn@scriptics.com>

        * tests/tcltest.test:
        * doc/tcltest.n:
        * library/tcltest1.0/tcltest.tcl: Removed the extra return at the
        end of the tcltest.tcl file, added version information about tcl.

        Applied patches sent in by Andreas Kupries to add helper procs for
        debug output, add 3 new flags (-testsdir, -load, -loadfile), and
        internally refactors common code for dealing with paths into
        separate procedures. [Bug: 2838, 2842]

        Merged code from core-8-2-1 branch that changes the checks for the
        value of tcl_interactive to also incorporate a check for the
        existence of the variable.

        * tests/autoMkindex.test:
        * tests/pkgMkIndex.test: Explicitly cd to
        ::tcltest::testsDirectory at the beginning of the test run

        * tests/basic.test: Use version information defined in tcltest
        instead of hardcoded version number

        * tests/socket.test: package require tcltest before attempting to
        use variable defined in tcltest namespace

        * tests/unixInit.test: 
        * tests/unixNotfy.test: Added explicit exits needed to avoid
        problems when the tests area run in wish.
        
1999-10-12  Jim Ingham  <jingham@scriptics.com>

        * mac/tclMacLoad.c: Stupid bug - we converted the filename to
        external, but used the unconverted version.
        * mac/tclMacFCmd.c: Fix a merge error in the bug fix for [Bug: 2869]

1999-10-12  Jeff Hobbs  <hobbs@scriptics.com>

        * generic/tclTest.c:
        * tests/reg.test: updated to Henry Spencer's new regexp engine
        (mid-Sept 99).  Should greatly reduce stack space reqs.

        * library/tcltest1.0/pkgIndex.tcl: fixed procs in pkgIndex.tcl file

        * generic/tclEnv.c: fixed mem leak with putenv and DStrings
        * doc/Encoding.3: corrected docs
        * tests/basic.test: updated test cases for 8.3
        * tests/encoding.test: fixed test case that change system
        encoding to a double-byte one (this causes a bogus mem read
        error for purify)
        * unix/Makefile.in: purify has to use -best-effort to instrument
        * unix/tclAppInit.c: identified potential mem leak when compiling
        tcltest (not critical)
        * unix/tclUnixPipe.c: fixed mem leak in TclpCreateProcess when
        doing alloc between vfork and execvp.
        * unix/tclUnixTest.c: fixed mem leak in findexecutable test command

1999-10-05  Jeff Hobbs  <hobbs@scriptics.com>

        * library/http2.1/http.tcl: fixed possible use of global c var.

        * win/tclWinReg.c: fixed registry command to properly 'get'

1999-09-21  Jennifer Hom  <jenn@scriptics.com>

        * library/tcltest1.0/tcltest.tcl: Applied patches sent in by
        Andreas Kupries to fix typos in comments and ::tcltest::grep,
        fix hook redefinition problems, and change "string compare" to
        "string equal." [Bug: 2836, 2837, 2839, 2840]

1999-09-20  Jeff Hobbs  <hobbs@scriptics.com>

        * win/tclWinSock.c: Added comment block to SocketThread()

        * tests/tcltest.test:

        * win/tclWinPipe.c:
        * win/Makefile.in: Fixing launching of 16-bit apps on Win9x from
        wish.  The command line was primed with tclpip82.dll, but it was

        * win/tclWinChan.c: Allow tcl to open CON and NUL, even for std
        channels.  Checking for bad/unusable std channels was moved to Tk
        since its only purpose was to check whether to use the Tk Console
        Window for the std channels.  [Bug: 2393 2392 2209 2458]

        * unix/mkLinks.tcl: Applied patch to avoid linking pack.n to

        seems to be a hang in threaded WinNT if the file isn't closed.
        Open issue, need to fix that hang.

        * tests/httpold.test:  Add time delay in response from Http server
        so that test cases can properly detect timeout conditions with
        threads enabled on multi-CPU WinNT.

        * tests/winFCmd.test:  Test case winFcmd-1.33 was looking for
        c:\windows, which may not exist.  Instead, create a new directory
        on c:\ and use it for the test.

        * win/tclWinConsole.c:
        * win/tclWinPipe.c:
        * win/tclWinSock.c:  Fix terminating helper threads by holding any
        mutexes from the primary thread while waiting for the helper
        thread to terminate.  Without these changes, the test suite hangs
        on WinNT with 2 CPUs and threads enabled.  Open issue, seems to be
        a sporadic hang on dual CPU systems still (very rare).

1999-07-26  Jennifer Hom  <jenn@scriptics.com>

        * tests/tcltest.test:
        * library/tcltest1.0/tcltest.tcl:

        * tests/var.test:
        * generic/tclVar.c:  Fixed bug that caused a seg. fault when using
        "array set a(b) {}", which is a bad array name anyway.  Now the
        "array set" command will return an error in this case.  Added test
        case and fixed existing test. [Bug: 2427]

        * generic/tcl.decls:
        * generic/tclDecls.h:
        * generic/tclUtf.c: Changed function declarations in
        non-platform-specific public APIs to use "unsigned long" instead of
        "size_t", which may not be defined on certain compilers (rather
        than include sys/types.h, which may not exist).
        
        * unix/Makefile.in: Added the Windows configure script to the
        distribution file list, already shipping configure.in and the .m4
        files, but needed the configure script itself.
        
        * win/makefile.vc: Changed version number of DDE package in VC++
        makefile to use 1.1 instead of 1.0.

        * doc/open.n: Added documentation of \\.\comX notation for opening
        serial ports on Windows (alternative to comX:).
        
        * tests/ioCmd.test:
        * doc/open.n:
        * win/tclWinSerial.c: Applied patch from Rolf Schroedter to add
        -pollinterval option to fconfigure to modify the maxblocktime used
        in the fileevent polling. Added documentation and fixed the test
        case as well.
        
        * win/tclWinSock.c: Modified 8.1.0 version of the Win32 socket
        driver to move the handling of the socket event window in a
        separate thread.  It also turned out that Win95 & Win98 were, in
        some cases, getting multiple FD_ACCEPTs but only handling one.
        Added a count for the FD_ACCEPT to take care of this.  Tested on
        NT4 SP3, NT4 SP4, Win95, and Win98.

1999-07-21    <jpeek@scriptics.com>

        * README: Small tweaks to clean up typos and wording.

1999-07-20  Melissa Hirschl  <hershey@matisse.scriptics.com>

        * generic/tclInitScript.h: 
        * unix/tclUnixInit.c: merged code with 8.0.5.  We now use an
        intermediate global tcl var "tclDefaultLibrary" to keep the
        "tcl_library" var from being set by the default value in the
        Makefile.  Also fixed a bug in which caused the value of
        TCL_LIBRARY env var to be ignored.
        * unix/tclWinInit.c: just updated some comments.

1999-07-19  Melissa Hirschl  <hershey@matisse.scriptics.com>

        * library/http2.1/http.tcl: updated -useragent text to say version
        2.1.

1999-07-16    <redman@scriptics.com>

        * generic/tcl.decls:
        * generic/tclDecls.h:
        * generic/tclStubInit.c:  Add Tcl_SetNotifier to stub table.
        [Bug: 2364]
        
        * unix/aclocal.m4:
        * unix/tcl.m4:  Add check for Alpha/Linux to correct the IEEE
        floating flag to the compiler, should be -mieee.  Patch from Don
        Porter.
        
        * tools/tcl.hpj.in: Change version number of .cnt file referenced
        in .HPJ file.

1999-07-12    <jpeek@scriptics.com>

        * doc/re_syntax.n: Removed two notes to myself (oops), cleaned
        up wording, fixed changebars, made two examples easier to read.

1999-07-11    <redman@scriptics.com>

        * win/makefile.vc: Since the makefile.vc should continue to work
        while we're working out bugs/issues in the new TEA-style
        autoconf/configure/gmake build mechanism for Windows, the version
        numbers of the Tcl libraries need to remain in sync.  Modified the
        version numbers in the makefile to reflect the change to 8.2b1.

1999-07-09    <redman@scriptics.com>

        * win/configure.in: Eval DLLSUFFIX, LIBSUFFIX, and EXESUFFIX in
        the configure script so that substitutions get expanded before
        being placed in the Makefile.  The "d" portion for debug libraries
        and DLLs was not being set properly.
        
1999-07-08    <stanton@scriptics.com>

        * tests/string.test: 
        * generic/tclCmdMZ.c: Fixed bug in string range bounds checking
        code.

1999-07-08  Jennifer Hom  <jenn@scriptics.com>

        * doc/tcltest.n:
        * library/tcltest1.0/tcltest.tcl: Removed -asidefromdir and
        -relateddir flags, removed unused ::tcltest::dotests proc, cleaned
        up implementation of core file checking, and fixed the code that
        checks for 1-letter flag abbreviations.

1999-07-08    <stanton@scriptics.com>

        * win/Makefile.in: Added tcltest target so runtest works
        properly.  Added missing names to the clean/distclean targets.

        * tests/reg.test: 
        * generic/rege_dfa.c: Applied fix supplied by Henry Spencer for
        bug in DFA state caching under lookahead conditions.  [Bug: 2318]

1999-07-07    <stanton@scriptics.com>

        * doc/fconfigure.n: Clarified default buffering behavior for the
        standard channels. [Bug: 2335]

1999-07-06    <redman@scriptics.com>

        * win/tclWinSerial.c:  New implementation of serial port driver
        from Rolf Shroedter (Rolf.Schroedter@dlr.de) that allows more than
        one byte to be read from the port.  Implemented using polling
        instead of threads, there is a max. 10ms latency between checking the
        port for file events.  [Bug: 1980 2217]

1999-07-06    <welch@scriptics.com>

        * library/http2.0/http.tcl: Fixed the -timeout option so it
        handles timeouts that occur during connection attempts to
        hosts that are down (the only case that really matters!)

1999-07-03    <welch@scriptics.com>

        * doc/ChnlStack.3:
        * generic/tcl.decls:
        * generic/tclIO.c: Added a new variant of the "Trf patch"
        from Andreas Kupres that adds new C APIs Tcl_StackChannel,
        Tcl_UnstackChannel, and Tcl_GetStackedChannel.

        * unix/tclXtNotify.c:
        * win/tclWinNotify.c:
        * mac/tclMacNotify.c: Added Tcl_SetNotifier and the associated
        hook points in the notifiers to be able to replace the notifier
        calls at runtime  The Xt notifier and test program use this hook.

1999-07-03    <welch@scriptics.com>

        * generic/tclParse.c: Changed parsing of variable names to
        allow empty array names.  Now "$(foo)" is a variable reference!
        Previous you had to use something like $::(foo), which is slower.
        This change is requested by Jean-Luc Fontaine for his STOOOP
        package.

1999-07-01    <redman@scriptics.com>

        * generic/tclCmdAH.c:
        * generic/tclFCmd.c: Call TclStat instead of TclpStat in order to
        allow Tcl_Stat hooks to work properly.

1999-06-29  Jennifer Hom  <jenn@scriptics.com>

        * library/tcltest1.0/pkgIndex.tcl:
        * library/tcltest1.0/tcltest.tcl:
        * doc/tcltest.n:
        * tests/all.tcl: Added -preservecore, -limitconstraints, -help,
        -file, -notfile, -relateddir and -asidefromdir flags to the
        tcltest package along with exported proc
        ::tcltest::getMatchingFiles.  The documentation was modified to
        match and all.tcl was modified to use the new functionality
        instead of implementing -file itself. 

1999-06-28    <redman@scriptics.com>

        * generic/tclIndexObj.c:
        * doc/GetIndex.3:
        * tests/binary.test:
        * tests/winDde.test: Applied patch from Peter Hardie (with
        changes) to fix problem with Tcl_GetIndexFromObj() when the key
        being passed is the empty string.  It used to match "" and return
        TCL_OK, but it should have returned TCL_ERROR instead.  Added test
        case to "binary" and "dde" commands to check the behavior.  Added
        documentation note as well.

1999-06-26    <redman@scriptics.com>

        * win/tclWinDde.c: Applied patch from Peter Hardie to add poke
        command to dde.  Also rev'd version of dde package to 1.1.

        * win/Makefile.in:
        * library/tcltest1.0/pkgIndex.tcl:
        * library/tcltest1.0/tcltest.tcl:
        * library/tcltest1.0: Added initial implementation of the Tcl test
        harness package.  This package was based on the defs.tcl file that
        was part of the tests directory. Reversed the way that tests were
        evaluated to fix a problem with false passes.

        * doc/tcltest.n: Added documentation for the tcltest package.

        * tests/README:
        * tests/defs.tcl:
        * tests/all.tcl: Modified all test files (tests/*.test) and
        all.tcl to use the new tcltest package and removed references to
        the defs.tcl file. Modified the README file to point to the man
        page for tcltest. 
        
1999-06-25    <stanton@scriptics.com>

        Unicode 2.1 data.  Also rationalized "regexp" and "string is"
        definitions of character classes.

1999-06-21    <stanton@scriptics.com>

        * unix/tclUnixThrd.c (TclpThreadCreate): Fixed memory leak where

        * generic/tclRegexp.c: 
        * generic/tcl.h: 
        * generic/tcl.decls: Renamed Tcl_RegExpMatchObj to
        Tcl_RegExpExecObj and added a new Tcl_RegExpMatchObj that is
        equivalent to Tcl_RegExpMatch.  Added public macros for the regexp
        compile/execute flags.  Changed to store either an object pointer
        or a string pointer in the TclRegexp structure.  Changed to avoid
        adding a reference to the object or copying the string.

        * generic/regcomp.c: lint

        * tests/reg.test: 
        * generic/regex.h: 
        * generic/regc_lex.c: Added REG_BOSONLY flag to allow Expect to

        * tests/execute.test:
        * generic/tclExecute.c (TclExecuteByteCode): Fixed crash caused by
        a bug in INST_LOAD_SCALAR1 where the scalar index was read as
        a signed 1 byte value instead of unsigned.  [Bug: 2243]

        * generic/tcl.h: 
        * generic/tcl.decls: Added Tcl_RegExpMatchObj and
        Tcl_RegExpGetInfo calls to access lower level regexp API.  These
        features are needed by Expect.  This is a preliminary
        implementation pending final review and cleanup.

        * generic/tclCmdMZ.c:
        * tests/string.test: Fixed bug where string map failed on null
        strings.

        * generic/regexec.c: 
        * unix/tclUnixNotfy.c: lint

        because of serious problems with the new driver.  Basically no
        incoming socket connections would be reported to a server port.
        The 8.1.1 code needs to be redesigned and fixed correctly.

1999-06-07  Melissa Hirschl  <hershey@matisse.scriptics.com>

        * tests/string.test: 
        * generic/tclVar.c (Tcl_SetVar2Ex):

        * generic/tclCmdMZ.c (Tcl_StringObjCmd): optimized the string
        index, string length, string range, and append command in cases
        where the object's internal rep is a bytearray.  Objects with
        other internal reps are converted to have the new unicode internal

        and an empty pattern is used in regexp ( such as {} or "" ).

1999-05-18    <stanton@scriptics.com>

        * win/tclWinChan.c: Modified initialization code to avoid
        inherenting closed or invalid channels.  If the standard input is
        anything other than a console, file, serial port, or pipe, then we
        fall back to the standard Tk window console.

1999-05-14    <stanton@scriptics.com>

        * generic/tclCmdAH.c (Tcl_ForObjCmd): Fixed crash caused by
        failure to reset the result before evaluating the test
        expression. 

1999-05-14    <surles@scriptics.com>

        * generic/tclBasic.c (Tcl_CreateInterp): Added introspection
        variable for threaded interps.  If the interp was compiled with
        threads enabled, the tcl_platform(threaded) variable will exist.

1999-05-14    <redman@scriptics.com>

        * generic/tclDate.c: Applied patch to fix 100-year and 400-year
        boundaries in leap year code, from Isaac Hollander.  [Bug: 2066]

1999-05-13    <stanton@scriptics.com>

        * unix/Makefile.in:
        * unix/tclAppInit.c: Minor cleanup related to Xt notifier.
        
        * unix/tclUnixInit.c (TclpSetInitialEncodings): Tcl now looks for
        an encoding subfield in the LANG/LC_ALL variables in cases where
        the locale is not found in the locale table.  Ensure that
        setlocale() is called at least once so X11 will initialize
        properly.  Also, forces the LC_NUMERIC locale to be "C" so numeric
        processing in scripts is not affected by the current locale
        setting. [Bug: 1989]

        * generic/tclRegexp.c: Increased per-thread regexp cache to 30
        slots.  This seems to be about the right number for larger
        applications like exmh.  [Bug: 1063]

1999-05-12    <stanton@scriptics.com>

        * doc/tclsh.1: Updated references to rc script names to accurately
        reflect the platform differences on Windows.

        * tests/regexp.test: 
        * generic/tclInt.h: 
        * generic/tclBasic.c: 
        * generic/tclRegexp.h:
        * generic/tclRegexp.c: Replaced the per-interpreter regexp cache
        with a per-thread cache.  Changed the Regexp object to take
        advantage of this extra cache.  Added a reference count to the
        TclRegexp type so regexps can be shared by multiple objects.
        Removed the per-interp regexp cache from the interpreter.  Now
        regexps can be used with no need for an interpreter. [Bug: 1063]

        * win/tclWinInit.c (TclpSetVariables): Avoid calling GetUserName
        if the value can be determined from the USERNAME environment
        variable.  GetUserName is very slow.

1999-05-07    <stanton@scriptics.com>

        * win/winDumpExts.c: 
        * win/makefile.vc: Removed incorrect patch. [Bug: 1998]
        
        * generic/tcl.decls: Replaced const with CONST.

        * generic/tclResult.c (Tcl_AppendResultVA): 
        * generic/tclStringObj.c (Tcl_AppendStringsToObjVA): Fixed to copy
        arglist using memcpy instead of assignment so it works properly on
        OS/390. [Bug: 1997]

        * generic/tclLoadNone.c: Updated to use current interfaces, added
        TclpUnloadFile. [Bug: 2003]

        * win/winDumpExts.c: 
        * win/makefile.vc: Changed to emit library name in defs
        file. [Bug: 1998]

        * unix/configure.in: Added fix for OS/390. [Bug: 1976]

1999-05-06    <stanton@scriptics.com>

        * tests/string.test: 
        * generic/tclCmdMZ.c: 
        * doc/string.n: Fixed bug in string equal/compare code when using
        -length option.  Cleaned up docs a bit more.

        * tests/http.test: Unset "data" array before running tests to
        avoid failures due to previous tests.

        * doc/string.n: 
        * tests/cmdIL.test: 
        * tests/cmdMZ.test: 
        * tests/error.test: 
        * tests/ioCmd.test: 
        * tests/lindex.test:

        * tests/lrange.test: 
        * tests/lreplace.test: 
        * tests/string.test: 
        * tests/cmdIL.test: 
        * generic/tclUtil.c: 
        * generic/tclCmdMZ.c: Replaced "string icompare/iequal" with
        -nocase and -length switches to "string compare/equal".  Added a
        -nocase option to "string map".  Changed index syntax to allow
        integer or end?-integer? instead of a full expression.  This is
        much simpler with safeTcl scripts since it avoids double
        substitution issues.

        * doc/Utf.3: 
        * generic/tclStubInit.c: 
        * generic/tclDecls.h: 
        * generic/tclUtf.c:
        * generic/tcl.decls: Added Tcl_UtfNcmp and Tcl_UtfNcasecmp.

1999-05-05    <stanton@scriptics.com>

        * win/makefile.vc: Added encoding directory to install-libraries
        target.

1999-05-03    <stanton@scriptics.com>

        * doc/string.n: 
        * tests/cmdMZ.test: 
        * tests/string.test: 
        * generic/tclCmdMZ.c (Tcl_StringObjCmd): Changed "string length"
        to avoid regenerating the string rep of a ByteArray object.
        
        * tests/cmdIL.test: 
        * tests/cmdMZ.test: 
        * tests/error.test:

        * tests/string.test: 
        * generic/tclCmdMZ.c (Tcl_StringObjCmd): 
        * generic/tclUtil.c (TclGetIntForIndex): Applied Jeff Hobbs's
        string patch which includes the following changes [Bug: 1845]:
        
            - string compare now takes optional length arg (for strncmp
                behavior)
                            
            - added string equal (just a few lines of code blended
                in with string compare)
            
            - added string icompare/iequal for case-insensitive comparisons
            
            - string index's index can now be ?end[+-]?expression
                I made this change in the private TclGetIntForIndex,
                which means that the list commands also benefit, as
                well as string range, et al.
            
            - added [string repeat string count]
                Repeats given string  number of times
            
            - added string replace, string equiv to lreplace
              (quasi opposite of string range):
                        string replace first last ?string?
                Example of use, replacing end of string with ...
                should the string be more than 16 chars long:
                        string replace $string 16 end "..."
                This just returns the string len < 16, so it
                will only affect the long strings.
            
            - added optional first and last args to string to*
                This allows you to just affect certain regions of
                a string with the command (like just capping the
                first letter).  I found the original totitle to
                be too draconian to be useful.
            
            - added [string map charMap string]
                where charMap is a {from to from to} list that equates to
                what one might get from [array get].  Each  and 
                can be multiple chars (or none at all).  For Tcl/CGI users,
                this is a MAJOR speed booster.
        
        * generic/tclParse.c (Tcl_ParseCommand): Changed to avoid
        modifying eval'ed strings that are already null terminated.
        [Bug: 1793] 

        * tests/binary.test: 
        * generic/tclBinary.c (DupByteArrayInternalRep): Fixed bug where
        type was not being set in duplicated object. [Bug: 1975, 2047]

1999-04-30    <stanton@scriptics.com>
        
        * Changed version to 8.1.1.
        
1999-04-30    <stanton@scriptics.com>

        * Merged changes from 8.1.0 branch:

        * generic/tclParse.c: Fixed memory leak in CommandComplete.

        * generic/tclPlatDecls.h: 
        * generic/tclIntPlatDecls.h: 
        * generic/tclIntDecls.h: 
        * generic/tclDecls.h: 
        * tools/genStubs.tcl: Added 'extern "C" {}' block around the stub
        table pointer declaration so the stub library can be used from
        C++. [Bug: 1934]

        * Lots of documentation and other release engineering fixes.

1999-04-28    <stanton@scriptics.com>

        * mac/tclMacResource.c: 
        * generic/tclListObj.c: 
        * generic/tclObj.c: 
        * generic/tclStringObj.c: Changed to avoid freeing the string
        representation before freeing the internal rep.  This helps with
        debugging since the string rep will still be valid when the free
        proc is invoked.

1999-04-27    <stanton@scriptics.com>

        * generic/tclLiteral.c (TclHideLiteral): Fixed so hidden literals
        get duplicated to avoid accidental sharing in the global object
        table. 

1999-04-23    <stanton@scriptics.com>

        * generic/tclStubInit.c: 
        * tools/genStubs.tcl: Changed to avoid the need for forward
        declarations in stub initializers.

1999-04-23    <stanton@scriptics.com>

        * library/encoding/koi8-r.enc:
        * tools/encoding/koi8-r.txt: Added support for the koi8-r Cyrillic
        encoding. [Bug: 1771]

1999-04-22    <stanton@scriptics.com>

        * win/tclWinFCmd.c:
        * win/tclWin32Dll.c: Changed uses of "try" to "__try", since that
        is the actual keyword.  This eliminates the need for some -D flags
        from the makefile.

        * generic/tclPort.h: Added include of tcl.h since it defines
        various Windows macros that are needed before deciding which
        platform porting file to use.

        * generic/tclEvent.c: lint

        * win/tclWinInit.c (TclpInitPlatform): Added call to TclWinInit
        when building a static library since DllMain will not be invoked.
        This could break old code that explicitly called TclWinInit, but
        should be simpler in the long run.

1999-04-22  Scott Stanton  <stanton@scriptics.com>

        * generic/tclInt.h: 
        * generic/tclInt.decls: 
        * generic/tclCompile.c: Added TclSetByteCodeFromAny that takes a
        hook procedure to invoke after compilation but before the byte
        codes are emitted.  This makes it possible to do postprocessing on
        the compiled byte codes before the ByteCode is generated.

        * generic/tclLiteral.c: Added TclHideLiteral and TclAddLiteralObj
        to make it possible to create local unshared literal objects.
        
        * win/tclWinInit.c:
        * unix/tclUnixInit.c: Changed initial search path to match that
        found used by tcl_findLibrary.

1999-04-22    <redman@scriptics.com>

        * win/tclWinPort.h:
        * win/tclWinSock.c: Added code to use WinSock 2.0 API on NT to
        avoid creating a window to handle sockets.  API not available on
        Win95 and needs to be fixed on Win98, until then continue to use
        the older (window-based) scheme on those two OSes.
        
1999-04-15    <stanton@scriptics.com>

        * Merged 8.1 back into the main trunk

1999-04-13    <stanton@scriptics.com>

        * library/encoding/gb2312.enc:
        * library/encoding/euc-cn.enc:
        * tools/encoding/gb2312.txt:
        * tools/encoding/cp950.txt:
        * tools/encoding/Makefile: Restored the double byte definition of
        GB2312 and added the EUC-CN encoding.  EUC-CN is a variant of
        GB2312 that shifts the characters into bytes with the high bit set
        and includes ASCII as a subset. [Bug: 632]

1999-04-13    <redman@scriptics.com>

        * win/tclWinSock.c: Apply patch to allow write access to a socket
        if FD_WRITE is sent but FD_CONNECT is not.  Some strange problem
        with either Win32 or a socket driver.  [Bug: 1664 1776]

1999-04-09    <redman@scriptics.com>

        * unix/tclUnixNotfy.c: Fixed notifier deadlock situation when the
        pipe used to talk back notifier thread is filled with data.  When
        calling the write() function to feed data down that pipe, unlock
        the notifierMutex to allow the notifier to wake up again.  Found
        as a result of the focus.test for Tk hanging. [Bug: 1700]

1999-04-06    <stanton@scriptics.com>

        * tests/unixNotfy.test: Fixed hang in tests when built with thread
        support. 

        * tests/httpold.test: Fixed broken test that didn't wait long
        enough for events to arrive.

        * tests/unixInit.test: Fixed race condition in test.
        
        * tests/unixInit.test: 
        * tests/fileName.test: Minor test nits.

        * unix/tclUnixInit.c (TclpSetInitialEncodings): Fixed bad initial
        encoding string.

1999-04-06    <surles@scriptics.com>

        * generic/tclVar.c: 
        * generic/tclEnv.c: Moved the "array set" C level code into a
        common routine (TclArraySet).  The TclSetupEnv routine now uses
        this API to create an env array w/ no elements.

        * generic/tclEnv.c:
        * generic/tclWinInit.h:
        * generic/tclUnixInit.h:
        * generic/tclInt.h: Made the Env module I18N compliant.  Changed the
        FindVariable routine to TclpFindVariable, that now does a case
        insensitive string comparison on Windows, and not on UNIX. [Bug:
        1299, 1500]

1999-04-05    <stanton@scriptics.com>

        * tests/io.test: Minor test cleanup.

        * generic/tclEncoding.c (Tcl_CreateEncoding): Minor lint to make
        it easier to compile on Digital-unix. [Bug: 1659]

        * unix/configure.in: 
        * unix/tclUnixPort.h: Applied patch for OS/390 to handle lack of
        sys/param.h. [Bug: 1725]

        * unix/configure.in: Fixed BSD/OS 4.* configuration to support
        shared libraries properly. [Bug: 1730]
        
1999-04-05    <redman@scriptics.com>

        * win/tclWinDde.c: decrease timeout value for DDE calls to 30k
        [Bug: 1639]

        * generic/tcl.decls:
        * generic/tcl.h:
        * generic/tclDecls.h:
        * generic/tclInt.decls:
        * generic/tclInt.h:
        * generic/tclIntDecls.h:
        * generic/tclStubInit.c:
        * generic/tclUtil.c: Added more functions to the Tcl stubs table,
        including all Tcl_ functions not already in it (except Cmd
        functions) and Tcl_GetCwd() and Tcl_Chdir() (new functions).
        
        * tests/safe.test:
        * doc/safe.n:
        * generic/tclBasic.c:
        * library/safe.tcl: The encoding command is not safe as-is, so
        create a safe alias to mask out the "encoding system <name>" but
        allow all other uses including "encoding system". Added test cases
        and updated the man page for Safe Tcl.

1999-04-05    <stanton@scriptics.com>

        * tests/winTime.test: 
        * win/tclWinTime.c: Fixed crash in clock command that occurred
        when manipulating negative time values in timezones east of
        GMT. [Bug: 1142, 1458]
        
        * tests/platform.test: 
        * tests/fileName.test: Fixed broken tests.
        
        * generic/tclFileName.c: Moved global regexps into thread local
        storage.

        * tests/socket.test: Changed so tests don't reuse sockets,
        since Windows is slow to release sockets.

        * win/tclWinConsole.c: 
        * win/tclWinPipe.c: 
        * win/tclWinSerial.c: Fixed race condition where background
        threads were terminated while they still held a lock in the
        notifier. 

1999-04-02    <stanton@scriptics.com>

        * tests/http.test: Fixed bad test initialization code.

        * generic/tclThreadTest.c (ThreadExitProc): Fixed bug where static
        memory was being returned instead of a dynamically allocated
        result in error cases.

1999-04-02    <redman@scriptics.com>

        * doc/dde.n:
        * tools/tcl.wse.in:
        * win/makefile.vc:
        * win/pkgIndex.tcl:
        * win/tclWinDde.c:  Add new DDE package, code removed from Tk now
        separated into its own package.  Changed DDE-based send code into
        "dde eval" command.  Can be loaded into tclsh (not just wish).
        Windows only.

1999-04-02    <stanton@scriptics.com>

        * tests/expr.test: 
        * tests/for-old.test: 
        * tests/for.test: 
        * tests/foreach.test: 
        * tests/format.test: 
        * tests/httpold.test:

        * tests/init.test: 
        * tests/interp.test: 
        * tests/while.test:  Added some tests for known bugs (marked with
        knownBug constraint), and cleaned up a few bad tests.

        * generic/regc_locale.c: 
        * generic/regcustom.h: 
        * generic/tcl.decls: 
        * generic/tclCmdIL.c:

        * generic/tclRegexp.c: 
        * generic/tclScan.c: 
        * generic/tclTest.c:
        * generic/tclUtf.c: 
        * win/tclWinFCmd.c: 
        * win/tclWinFile.c: Made various Unicode utility functions
        public. The following functions were made public and added to the
        stubs table: 
                Tcl_UtfToUniCharDString, Tcl_UniCharToUtfDString,
                Tcl_UniCharLen, Tcl_UniCharNcmp, Tcl_UniCharIsAlnum,
                Tcl_UniCharIsAlpha, Tcl_UniCharIsDigit, Tcl_UniCharIsLower,
                Tcl_UniCharIsSpace, Tcl_UniCharIsUpper, Tcl_UniCharIsWordChar

1999-04-01    <stanton@scriptics.com>

        * tests/registry.test: 
        * win/tclWinReg.c: Internationalized the registry code.  It now
        uses Unicode interfaces on NT. [Bug: 1197]

        * tests/parse.test: 
        * generic/tclParse.c: Fixed crash due to multiple frees in parser
        during error cleanup when parsing commands with more tokens than
        will fit in the static area of the parse structure. [Bug: 1681]

        * generic/tclInt.h: Removed duplicate declarations.

        * generic/tclInt.decls: 
        * generic/tcl.decls: Added Tcl_WinUtfToTChar and Tcl_WinTCharToUtf
        to the tclPlat table.

        * win/makefile.vc: Applied patch from Jan Nijtmans to fix Ultrix
        multiple symbol definition problem.  Now, even Tcl includes a copy
        of the Tcl stub library.  Also fixed TCL_MEM_DEBUG mode (for Tk).

1999-03-31    <redman@scriptics.com>

        * win/tclWinConsole.c: WinNT has a bug when reading a single
        character from the console.  Rewrote the code for the console to
        read an entire line at a time using the reader thread.

1999-03-30    <stanton@scriptics.com>

        * unix/Makefile.in: Removed trailing backslash that broke the
        "depend" target.

        * unix/tclUnixInit.c (TclpSetInitialEncodings): Changed to avoid
        calling setlocale().  We now look directly at env(LANG) and
        env(LC_CTYPE) instead. [Bug: 1636]

        * generic/tclFileName.c: 
        * generic/tclDecls.h: 
        * generic/tcl.decls: Removed CONST from Tcl_JoinPath and
        Tcl_TranslateFileName because it changes the signature of
        Tcl_JoinPath in an incompatible manner.

        * generic/tclInt.h: 
        * generic/tclLoad.c (TclFinalizeLoad): 
        * generic/tclEvent.c (Tcl_Finalize): Defer unloading of loadable
        modules until all exit handlers have been invoked.

        changed the stub macros to just use the name without params. Pass
        &tclStubs into the interp (don't use tclStubsPtr because of
        collisions with the stubs on Solaris).
        
1999-03-27    <redman@scriptics.com>

        it's a stdio handle (GetStdHandle()) during shutdown of a thread
        to prevent it from destroying the stdio of other threads.

1999-03-26    <suresh@scriptics.com>

        * unix/configure.in
        --nameble-shared is now the default and build Tcl as a shared
        library; specify --disable-shared to build a static Tcl library
        and shell.

1999-03-25    <stanton@scriptics.com>

        * tests/interp.test: 
        * generic/tclInterp.c (AliasObjCmd): Changed so aliases are
        invoked at current scope in the target interpreter instead of at
        the global scope.  This was an incompatibility introduced in 8.1
        that is being removed. [Bug: 1153, 1556]

        * tools/encoding/gb2312.enc: Added ASCII to big5 and gb2312
        encodings. [Bug: 632]
        
        * generic/tclPkg.c (Tcl_PkgRequireEx): Fixed broken clientData
        initialization in package code.

        * unix/Makefile.in (dist): Added tcl.decls and tclInt.decls to
        source distribution. [Bug: 1571]

        * doc/Thread.3: Updated documentation of Tcl_MutexLock to indicate
        that the recursive locking behavior is undefined.  On Windows, it
        does not block, on Unix it deadlocks. [Bug: 1275]

1999-03-24    <stanton@scriptics.com>

        * tests/execute.test: 
        * generic/tclExecute.c (TclExecuteByteCode): Fixed expression code
        that incorrectly returned floating point values for integers if
        the internal rep happened to be a double.  Now we check to see if
        the object has a string rep that looks like an integer before
        using the double internal rep. [Bug: 1516]

        * win/tclWinSerial.c: Fixed compilation warnings/errors for VC++
        5.0 and 6.0 and HP-UX native compiler without -Aa or -Ae. 
        [Bug: 1323 1518 1324 1583 1585 1586]

        * win/tclWinSock.c: Make sockets thread-safe on Windows. The
        current implementation uses windows to handle events on the
        socket, one for each thread (thread local storage). Previously,
        there was only one window shared between threads, which didn't
        work. [Bug: 1326]

1999-03-23    <stanton@scriptics.com>

        * tools/tcl.wse: Fixed file association to look in the right place
        for the wish icon. [Bug: 1544]

        * tests/winNotify.test: 
        * tests/ioCmd.test: 
        * tests/event.test: Changed to use new style conditionals.

        * tests/encoding.test: Fixed nonportable test.

        * unix/dltest/configure.in: 
        * unix/dltest/Makefile.in: Added missing DBGX macros. [Bug: 1564]

        * tests/winNotify.test: 
        * mac/tclMacNotify.c: 
        * win/tclWinNotify.c: 
        * unix/tclUnixNotfy.c:
        * generic/tclNotify.c: Added a new Tcl_ServiceModeHook interface
        that is invoked whenever the service mode changes.  This is needed
        to allow the Windows notifier to create a communication window the
        first time Tcl is about to enter an external modal event loop
        instead of at startup time.  This will avoid the various problems
        that people have been seeing where the system hangs when tclsh
        is running outside of the event loop. [Bug: 783]

        * generic/tclInt.h: 
        * generic/tcl.decls: Renamed TclpAlertNotifier back to
        Tcl_AlertNotifier since it is part of the public notifier driver
        API.

1999-03-23    <redman@scriptics.com>

        * win/tclWinSerial.c: Fixed problem with fileevent on the serial
        port and nonblocking mode.  Gets no longer hangs, fileevents fire
        whenever there is any character data on the port.
        
        * tests/winConsole.test:
        * win/tclWinConsole.c: Fixed problem with fileevents and gets from
        a console stdin.  Previously, fileevents were firing before an
        entire line was available for reading, which meant that when you
        did a gets or read, it blocked (even in nonblocking mode). Now, it
        should work the same as Unix: fileevents fire when an entire line
        is ready, and gets and read do not block in non-blocking mode.
        Added an interactive test case to check for this.

1999-03-22    <stanton@scriptics.com>

        * tests/reg.test: 
        * generic/regc_color.c: Applied regexp bug fix from Henry Spencer.

1999-03-19    <redman@scriptics.com>

        * generic/tclCmdIL.c: Fixed the initialization of an array so that
        the Sun 5.0 C compiler wouldn't complain.

        * unix/configure.in: Added support for --enable-64bit.  For now,
        this is only supported on Solaris 7 64bit (SunOS 5.7) using the Sun 
        compiler (not gcc).
        
1999-03-18    <stanton@scriptics.com>

        * win/tclWinChan.c (TclpOpenFileChannel, Tcl_MakeFileChannel):
        Changed to only test for console or comm handles when the type is
        FILE_TYPE_CHAR to avoid useless tests on simple files.  Also
        reordered tests so consoles are tested first as this is more
        common.

        * win/makefile.vc: Regularized usage of mkd and rmd and rm.

        * library/encoding/shiftjis.enc: 
        * tools/encoding/shiftjis.txt: Missing/incorrect characters in
        shift-jis table. [Bug: 1008, 1526]

        * generic/tclInt.decls:
        * generic/tcl.decls: Eliminated use of "string" and "list" from
        argument lists to avoid conflicts with C++ STL. [Bug: 1181]

        * win/tclWinFile.c (TclpMatchFiles): Changed to ignore the
        FS_CASE_IS_PRESERVED bit and always return exactly what we get
        from the system.

        * win/tclWinConsole.c: 
        * win/tclWinPipe.c: 
        * win/tclWinSerial.c: Changed so channel drivers wait for the
        reader/writer threads to exit before returning during a close
        operation.  This ensures that the main thread is the last thread
        to exit, so the process return value is set properly.

        * generic/tclInt.decls: Changed "const" to "CONST" in
        declarations for better portability.

        * generic/tcl.decls: Renamed panic and panicVA to Tcl_Panic and
        Tcl_PanicVA in the stub files.

        * generic/tclInterp.c (Tcl_MakeSafe): Remove tcl_platform(user)
        from safe interps.

1999-03-11    <stanton@GASPODE>

        * unix/Makefile.in:
        * unix/configure.in: Include compat files in the stub library in
        addition to the main library.  Compat files are now built for
        dynamic use in all cases.
        
        * generic/tcl.h: Changed magic number so it doesn't match the plus
        patch, at Jan's request.

        * unix/dltest/Makefile.in:

1999-03-10    <stanton@GASPODE>

        * generic/tcl.h: 
        * generic/tcl.decls: Changed Tcl_ReleaseType from an enum to
        macros so it can be used in .rc files.
        Added Tcl_GetString.

        * mac/tclMacNotify.c:
        * generic/tclNotify.c:
        * generic/tclInt.h: 
        * win/tclWinNotify.c: 
        * generic/tcl.h: Renamed Tcl_AlertNotifier to TclpAlertNotifier.

        * generic/tclInt.decls: Added TclWinAddProcess to make it possible
        for expect to use Tcl_WaitForPid().  This patch is from Gordon
        Chaffee. 

        * mac/tclMacPort.h: 
        * win/tclWinInit.c: 
        * unix/tclUnixPort.h: 
        * generic/tclAsync.c: Added TclpAsyncMark to fix bug in async
        handling on Windows where async events don't wake up the event
        loop.  This patch comes from Gordon Chaffee.

        * generic/tcl.decls: Fixed declarations of reserved slots.
        
1999-03-10    <redman@scriptic.com>

        * generic/tclCompile.h: Ensure that the ByteCode struct is binary
        compatible with the version in 8.0.6.

        * generic/tcl.h:
        * generic/tclBasic.c: Add Tcl_GetVersion() function to the public
        C API to allow programs to check the version number of the Tcl
        library at runtime.  Also added an enum to clarify the release
        level (alpha, beta, final).

1999-03-09    <stanton@GASPODE>

        * Integrated changes from Tcl 8.0 including:
                stubs mechanism
                configure patches from Jan Nijtmans
                rename of panic to Tcl_Panic
        
1999-03-08    <lfb@scriptics.com>

        * win/tclWin32Dll.c: Removed Dll instance from thread-local
        storage.

1999-03-08    <stanton@GASPODE>
        
        * generic/tcl.h: Moved Tcl_Mutex, etc. macros above the inclusion
        of tclDecls.h to avoid macro conflicts.

        * unix/tclUnixThrd.c:
        * generic/tclThreadTest.c:

        * win/makefile.vc:  
        * win/tclWinPort.h: Added Tcl stubs implementation.  There are
        now two new macros USE_TCL_STUBS and USE_TCL_STUB_PROCS that
        enable use of stubs and disable stub macros respectively.  All of
        the public and private function declarations from tcl.h and
        tclInt.h have moved into the *.decls files and the *Stubs.c and
        *Decls.h files are generated using the genStubs.tcl script.

        * unix/Makefile.in:
        * unix/configure.in: 
        * unix/ldAix: Enhanced AIX shared library support.

        * win/tclWinSock.c: Removed a bunch of extraneous PASCAL FAR
        attributes from internal functions.

        * win/tclWinReg.c: Changed registry package to use stubs mechanism
        so it no longer depends on the specific version of Tcl.

        * doc/AddErrInfo.3: 
        * doc/Eval.3:

        * generic/tclUtil.c:
        * unix/mkLinks: Added va_list versions of all VARARGS
        functions so they can be invoked from the stub functions.

        * doc/package.n: 
        * doc/PkgRequire.3: 
        * generic/tclPkg.c: Added Tcl_PkgProvideEx, Tcl_RequireEx,
        Tcl_PresentEx, and Tcl_PkgPresent.  Added "package present"
        command.

        * generic/tclFileName.c: 
        * mac/tclMacFile.c: 
        * mac/tclMacShLib.exp: 
        * unix/tclUnixFile.c: 
        * win/tclWinFile.c: Changed so TclGetUserHome is defined on
        all platforms, even though it is currently a noop on mac and
        windows, and renamed it to TclpGetUserHome.

        * generic/tclPanic.c:
        * generic/panic.c: Renamed panic to Tcl_Panic.
        
1999-02-25    <redman@scriptics.com>

        * win/makefile.vc: Added tclWinConsole.c and tclWinSerial.c
        
        * win/tclWinConsole.c: New code to properly deal with fileevents
        and nonblocking mode on consoles.
        
        * win/tclWinSerial.c: New code to properly deal with fileevents
        and nonblocking mode on serial ports.

        * win/tclWinPipe.c: 
        * win/tclWinPort.h: Exported functions to allow creation of pipe
        channels from tclWinChan.c

        * win/tclWinChan.c: Check the type of a channel, including for the
        standard (stdin/stdout/stderr), and use the correct channel type
        to create the channel (file, serial, console, or pipe).

1999-02-10    <stanton@GASPODE>

        * library/auto.tcl: Fixed auto_mkindex so it handles .tbc files.
        Did some general cleanup to handle bad eval statements that didn't
        use "list".

        * unix/mkLinks:
        * doc/SetVar.3:
        * generic/tcl.h:
        * generic/tclVar.c: Restored Tcl_ObjGetVar2 and Tcl_ObjSetVar2
        from 8.0. Renamed Tcl_Get/SetObjVar2 to Tcl_GetVar2Ex and
        Tcl_SetVar2Ex.

1999-02-10    <stanton@GASPODE>

        INTEGRATED PATCHES FROM 8.0.5b2: 

        * test/winPipe.test: Changed to remove echoArgs.tcl temporary file
        when done.
        
        * tests/cmdAH.test:
        * generic/tclFileName.c (TclGetExtension): Changed behavior so the
        split happens at the last period in the name instead of the first
        period of the last run of periods.  So, "foo..o" is split into
        "foo." and ".o" now. [Bug: 1126]
        
        * win/makefile.vc: Added better support for paths with spaces in
        the name. Added .lib and support .dlls to the install-binaries
        target.  Added generate of a pkgIndex.tcl script to the
        install-libraries target.

        * win/tclAppInit.c: 
        * unix/tclAppInit.c: 
        * mac/tclMacAppInit.c: 
        * generic/tclTest.c: Changed some EXTERN declarations to extern
        since they are not defining exported interfaces.  This avoids
        generating useless declspec() attributes and makes the windows
        makefile simpler.

        * generic/tcl.h: Moved Tcl_AppInit declaration to end and cleared
        out TCL_STORAGE_CLASS so it is not declared with a declspec().

        * tests/interp.test:
        * generic/tclInterp.c (DeleteAlias): Changed to use
        Tcl_DeleteCommandFromToken so we handle renames properly. This
        avoids senseless panic. [Bug: 736]

        * unix/tclUnixChan.c: 
        * win/tclWinSock.c: 
        * doc/socket.n: Applied Gordon Chaffee's patch to handle failures
        during asynchronous socket connection operations.  This adds a new
        "-error" fconfgure option to socket channels. [Bug: 893]

        * generic/tclProc.c:
        * generic/tclNamesp.c:
        * generic/tclInt.h: 
        * generic/tclCmdIL.c: 
        * generic/tclBasic.c: 
        * generic/tclVar.c: Applied patch from Viktor Dukhovni to
        rationalize TCL_LEAVE_ERR_MSG behavior when creating variables.
        
        * generic/tclVar.c: Fixed bug in namespace tail computation.
        Fixed bug where upvar could resurrect a namespace variable whose
        namespace had been deleted.

        * generic/tclCompile.c (TclCompileExprCmd): Eliminated yet another
        bogus optimization in expression compilation.

        * unix/configure.in: Added branch for BSD/OS-4* to shared library
        case statement. [Bug: 975]
        Fixed to correctly handle IRIX 6.5 n32 library support. [Bug: 1117]
        
        * win/winDumpExts.c: Patched to be pickier about stripping
        @'s. [Bug: 920]

        * library/http2.0/http.tcl: Added catch around eof test in
        CopyDone since the user may have already called http::reset.
        [Bug: 1108] 

        * unix/configure.in: Changed Linux and IRIX to set SHLIB_LIBS to
        LIBS so shared libraries are linked with the system
        libraries. [Bug: 1018]

        * generic/tclCompile.c (CompileExprWord): Fixed exception stack
        overflow bug caused by missing statement. [Bug: 928]

        * generic/tclIOCmd.c: 
        * generic/tclBasic.c: Objectified the "open" command. [Bug: 1113] 

        * generic/tclPosixStr.c (Tcl_ErrnoId, Tcl_ErrnoMsg): When using
        egcs, ENOTSUP and EOPNOTSUPP are the same, so now we handle that
        case. [Bug: 1137]

        * library/init.tcl: Various small changes requested by Jan Nijtmans.
        - If the variable $tcl_library contains the empty string, this
        empty string will be put in $auto_path. This is not useful at all,
        it only slows down later package processing.
        - If the variable tcl_pkgPath is not set, the "unset __dir"
        fails. Thich makes init.tcl totally unusable. Better put a "catch"
        around it. 
        - In the function tcl_findLibraries, the "string match" function
        only works correctly if $tcl_patchLevel is in one of the forms
        "?.?a?", "?.?b?" or "?.?.?". Could a "regexp" be used instead,
        then it allows anything to be appended to the patchLevel
        string. And it is more efficient.
        - The tclPkgSetup function assumes that if $type != "load" then
        the type must be "source". This needn't be true. Some users want
        to add their own setup types.
        [RFE: 1138] [Bug: 978]

        * win/tclWinReg.c: 
        * doc/registry.n: Added support for HKEY_PERFORMANCE_DATA and
        HKEY_DYN_DATA keys. [Bug: 1109]

        * win/tclWinInit.c (TclPlatformInit): Added code to ensure
        tcl_pkgPath is set to "" when no registry entry is found. [Bug: 978]

1999-02-01    <stanton@GASPODE>

        * generic/tclBasic.c:
        * generic/tclCmdAH.c:
        * generic/tclCmdIL.c:
        * generic/tclCmdMZ.c:
        * generic/tclExecute.c:
        * generic/tclHistory.c:
        * generic/tclIO.c:
        * generic/tclIOUtil.c:
        * generic/tclInterp.c:
        * generic/tclMain.c:
        * generic/tclNamesp.c:
        * generic/tclParse.c:
        * generic/tclProc.c:
        * generic/tclTest.c:
        * generic/tclTimer.c:
        * generic/tcl.h: Made eval interfaces compatible with 8.0 by
        renaming Tcl_EvalObj to Tcl_EvalObjEx, renaming Tcl_Eval2 to
        Tcl_EvalEx and restoring Tcl_EvalObj and Tcl_GlobalEvalObj
        interfaces so they match Tcl 8.0.

1999-01-28    <stanton@GASPODE>

        * Merged Tcl 8.0.5b1 changes.
        
        * generic/tclUtil.c (Tcl_DStringSetLength): Changed so the buffer
        overallocates in a manner similar to Tcl_DStringAppend.  This
        should improve performance for TclUniCharToUtfDString.

1998-12-11    === Tcl 8.1b1 Release ===
        
1998-12-10    <stanton@GASPODE>

        * Fixed lots of files that used TCL_THREAD instead of TCL_THREADS.
        
        * generic/tclEncoding.c (Tcl_FreeEncoding): Moved most of the code
        into a static FreeEncoding routine that does not grab the
        encodingMutex to avoid deadlocks/races when called from other
        routines that already have the mutex.

1998-12-09    <stanton@GASPODE>

        * library/msgcat1.0/msgcat.tcl: Fixed bad export list, fixed so
        all locale strings are converted to lower case, including file
        names.

        * generic/regcomp.c (makescan): Fixed bug in longest match case
        that caused anchored patterns to fail. [Bug: 897]

1998-12-08    <stanton@GASPODE>

        * library/msgcat1.0/msgcat.tcl: changed mc to invoke mcunknown in
        the calling context, changed locale lookups to be case insensitive

1998-12-07    <stanton@GASPODE>

        * generic/tclAlloc.c (TclpRealloc): Fixed a memory allocation bug
        where big blocks that were reallocated into a different heap
        location were not being placed into the bigBlocks list. [Bug: 933]

        * tests/msgcat.test: Added message catalog test suite.

        * library/msgcat1.0/msgcat.tcl: minor bug fixes, integrated latest
        changes from Mark Harrison.

1998-12-04    <stanton@GASPODE>

        * library/msgcat1.0/msgcat.tcl: Changed code to conform to Tcl
        coding standards.  Changed to use file join for portability.

        * library/msgcat1.0: Added initial implementaion of Tcl message
        catalog package contributed by Mark Harrison.

1998-12-03    <stanton@GASPODE>

        * win/tclWinPipe.c (BuildCommandLine): Fixed bug that kept
        arguments containing spaces from being properly quoted.

        * tests/defs: Changed so auto_path is set to only contain the Tcl
        library directory.  This keeps the tests from accidentally picking
        up stuff in installed packages. 

        * generic/tclUtil.c (Tcl_StringMatch): Changed to match 8.0
        behavior in corner case where there is no closing bracket.

1998-12-02    <stanton@GASPODE>

        * win/tclWinPipe.c (TclpCreateCommandChannel): Changed
        reader/writer threads to have THREAD_PRIORITY_HIGHEST so they will
        have a chance to run whenever there is something to do.

        * generic/tclIO.c (WriteBytes, WriteChars): Fixed so extraneous
        flushes do not happen in line mode.
        (TranslateOutputEOL): Made translation more efficient in line mode
        and fixed a buffer overflow bug in CRLF translation. [Bug: 887]

1998-12-02    <welch@SAGE>

        * Updated patchlevel to 8.1b1

1998-12-02    <stanton@GASPODE>

        * generic/regc_color.c (subcolor): Added check for error case to
        avoid an out of bounds array reference.

        * generic/tclCmdAH.c (Tcl_EncodingObjCmd): Changed to avoid using
        Tcl_DStringResult because it is not binary clean.

        * generic/tclParse.c (Tcl_ParseCommand): Fixed bug in comment
        parsing where a trailing comment looked like an incomplete
        command. 

1998-12-02    <welch@SAGE>

        * Merged changes from 8.0.4, especially the new pkg_mkIndex

1998-12-01    <stanton@GASPODE>

        * generic/tclIO.c (Tcl_ReadChars): Added a call to UpdateInterest
        so we don't block when there is data sitting in the buffers.

        * generic/tclTest.c (TestevalobjvObjCmd): Updated for EvalObjv
        change.

        * tests/parse.test: Updated tests for EvalObjv change.

        * generic/tclParse.c (EvalObjv, Tcl_EvalObjv): Changed
        Tcl_EvalObjv interface to remove string and length arguments,
        preserved original interface as EvalObjv for internal use.

        * generic/tcl.h: Changed Tcl_EvalObjv interface to remove string
        and length arguments.

        * doc/Eval.3: Updated documentation for Tcl_EvalObjv to remove
        string and length arguments.

        * generic/tclCompCmds.c (TclCompileForeachCmd): Fixed code that
        corrupted the exceptDepth value in the compile environment when
        foreach failed to compile inline. [Bug: 884]

        * library/encoding/euc-kr.enc: 
        * library/encoding/ksc5601.enc: 
        * tools/encoding/ksc5601.txt: 
        * unix/tclUnixInit.c: Added support for Korean EUC. 

        * win/tclWinChan.c (TclpGetDefaultStdChannel): added check for a
        failure during Tcl_MakeFileChannel.

1998-11-30    <stanton@GASPODE>

        * unix/tclUnixNotfy.c (Tcl_WaitForEvent): Fixed hang that occurs
        when trying to close a pipe that is currently being waited on by
        the notifier thread. [Bug: 607]

        * unix/tclUnixFCmd.c (GetPermissionsAttribute): Increase size of
        returnString buffer to avoid overflow. [Bug: 584]

        * generic/tclThreadTest.c (TclThreadSend): Fixed memory leak due
        to use of TCL_VOLATILE instead of TCL_DYNAMIC.

        * generic/tclThread.c (TclRememberSyncObject): Fixed memory leak
        caused by failure to reuse condition variables.

        * unix/tclUnixNotfy.c:  (Tcl_AlertNotifier, Tcl_WaitForEvent,
        NotifierThreadProc, Tcl_InitNotifier): Fixed race condition caused
        by incorrect use of condition variables when sending messages
        between threads.. [Bug: 607]

        * generic/tclTestObj.c (TeststringobjCmd): MAX_STRINGS was off by one
        so the strings array was too small.

        * generic/tclCkalloc.c (Tcl_DbCkfree): Moved mutex lock so
        ValidateMemory is done inside the mutex to avoid a race condition
        when validate_memory is enabled. [Bug: 880]

1998-11-23    <stanton@GASPODE>

        * regexec.c: more performance tuning from Henry Spencer.

1998-11-17    <stanton@GASPODE>

        * tclScan.c: moved "scan" implementation out of tclCmdMZ.c and
        added Unicode support.  This required a complete reimplementation
        of the command to avoid using scanf(), which isn't Unicode aware.
        Two new features were added in the process: %n to return the
        current number of characters consumed, and XPG3-style %n$ argument
        order specifiers similar to those provided by the "format"
        command. [Bug: 833]

        * tclAlloc.c: changed so allocated memory is always 8-byte aligned
        to improve memory performance and to ensure that it will work on
        systems that don't like accessing 4-byte aligned values
        (e.g. Solaris and HP-UX). [Bug: 834]

1998-11-06    <stanton@GASPODE>

        * tclVar.c (TclGetIndexedScalar): Fixed bug 796, var name was
        getting lost before being passed to CallTraces.

1998-10-21    <stanton@GASPODE>

        * added "encoding" command
        
        * Moved internal regexp declarations from tclInt.h to tclRegexp.h

        * integrated regexp updates from Henry Spencer

1998-10-15    <stanton@GASPODE>

        * tclUtf.c: added Unicode character table support

        * tclInt.h: added TclUniCharIsWordChar

        * tclCmdMZ.c (Tcl_StringObjCmd): added "totitle" subcommand,
        changed "wordend" and "wordstart" to properly handle Unicode word
        characters and connector punctuation

1998-10-05    <stanton@GASPODE>

        * auto.tcl, package.tcl: fixed SCCS strings

        * tclIndex: updated index to reflect 8.1 files

        * tclCompile.c (TclCompileScript): changed to avoid modifying the
        input string in place because name lookup operations could have
        arbitrary side effects

        * tclInterp.c: added guard against deleting current interpreter

        * tclMacFile.c, tclUnixFile.c, tclWinFile.c, tclFileName.c: added
        warnings around code that modifies strings in place

        * tclExecute.c: fixed off-by-one copying error, fixed merge bugs

        * tclEvent.c: changed so USE_TCLALLOC is tested for value instead
        of definition

        * tclCompCmds.c: replaced SCCS strings, added warnings around code
        that modifies strings in place

        * interp.test: added test for interp deleting itself

1998-09-30    <stanton@GASPODE>

        * makefile.vc: fixed so TCL_LIBRARY is set before running tcltest

        * tclWin32Dll.c: removed TclpFinalize, cleanup of merges
