1999-06-17    <[e-mail]>

	* tests/regexp.test: 
	* generic/tclCmdMZ.c: 
	* generic/tclCmdIL.c: Changed to use new regexp interfaces.  Added

	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:

1999-06-16  Melissa Hirschl  <[e-mail]>

	* generic/tclVar.c (Tcl_VariableObjCmd): fixed premature increment
	in loop that was causing out-of-bounds reads on array "varName".

1999-06-16    <[e-mail]>

	* 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]

1999-06-14  Melissa Hirschl  <[e-mail]>

	* doc/StringObj.3
	* test/stringObj.test
	* unix/Makefile.in
	* win/Makefile.in
	* win/makefile.vc
	* generic/tclStringObj.c:
	Merged String and Unicode object types.  Added new functions to
	the puplic API:  Tcl_NewUnicodeObj, Tcl_SetUnicodeObj,
	Tcl_GetUnicode, Tcl_GetUniChar, Tcl_GetCharLength, Tcl_GetRange,
	Tcl_AppendUnicodeToObj.

1999-06-09    <[e-mail]>

	* generic/tclUnicodeObj.c: Lots of cleanup and simplification.
	Fixed several memory bugs.  Added TclAppendUnicodeToObj.  

	* generic/tclInt.h: Added declarations for various Unicode string
	functions.  

	* generic/tclRegexp.c: 
	* generic/tclCmdMZ.c: Changed to use new Unicode string interfaces
	for better performance. 
	
	* generic/tclRegexp.h: 
	* generic/tclRegexp.c: 
	* 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.

1999-06-08    <[e-mail]>

	* win/tclWinSock.c: Rolled back to the 8.1.0 implementation
	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  <[e-mail]>

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

	* unix/Makefile.in: 
	* win/Makefile.in: 
	* win/Makefile.vc: 
	* tests/unicode.test: 
	* generic/tclInt.h:
	* generic/tclObj.c:
	* generic/tclUnicodeObj.c: added a new object type to store the
	unicode representation of a string.

	* generic/tclTestObj.c: added the objtype option to the testobj
	command.  This option returns the name of the type of internal rep
	an object has.

1999-06-04    <[e-mail]>

	* win/configure.in: 
	* win/Makefile.in: Windows build now handles static/dynamic
	debug/nodebug builds and supports the standard targets using
	Cygwin user tools plus GNU make and autoconf.

1999-06-03    <[e-mail]>

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): 
	* tests/string.test: Fixed bug where string equal/compare -nocase
	reported wrong result on null strings. [Bug: 2138]

1999-06-02    <[e-mail]>

	* generic/tclUtf.c (Tcl_UtfNcasecmp): Fixed incorrect computation
	of relative ordering. [Bug: 2135]

1999-06-01    <[e-mail]>

	* unix/configure.in: Fixed various small configure.in patches
	submitted by Jan Nijtmans. [Bug: 2121]

	* generic/regexec.c: 
	* generic/regfree.c: 
	* generic/regfronts.c: 
	* generic/regguts.h: 
	* generic/tclCmdMZ.c: 
	* generic/tclRegexp.c: 
	* generic/tclRegexp.h: 
	* generic/tclTest.c: Applied Henry Spencer's latest regexp patches
	that fix an infinite loop bug and add support for testing whether
	a string could match with additional input.  [Bug: 2117]

1999-05-28    <[e-mail]>

	* generic/tclObj.c: Changed to eliminate use of isupper/tolower in
	favor of the Unicode versions.

	* win/Makefile.in:
	* win/configure.in: Added preliminary TEA implementation.

	* win/tclWinDde.c: Fixed bug where dde calls were being passed an
	invalid dde handle because Initialize had not been called.
	[Bug: 2124]

1999-05-26    <[e-mail]>

	* generic/tclThreadTest.c: Fixed race condition in testthread
	code that showed up in the WinNT test suite intermittently.

	* win/tclWinSock.c: Fixed a hang in the WinNT socket driver, wake
	up the socket thread every 100ms to check for events on the
	sockets that did not wake up the thread (race condition).

1999-05-24    <[e-mail]>

	* tools/genStubs.tcl: Changed to allow a list of platforms instead
	of just one at a time.

	* generic/tcl.decls: 
	* generic/tclCmdMZ.c: 
	* generic/tclDecls.h: 
	* generic/tclInt.decls: 
	* generic/tclIntDecls.h: 
	* generic/tclPort.h: 
	* generic/tclStubInit.c: 
	* generic/tclStubLib.c: Various header file related changes and other
	lint to try to get the Mac builds working.

1999-05-21    <[e-mail]>

	* win/tclWinPipe.c: Fix bug when launching command.com on
	Win95/98.  Need to wait for the procInfo.hProcess of the process that
	was created, not the hProcess of the current process.  [Bug: 2105]

1999-05-20    <[e-mail]>

	* library/init.tcl: Add the directory where the executable is, and
	the ../lib directory relative to that, to the auto_path variable.
	
1999-05-19    <[e-mail]>

	Merged in various changes submitted by Jeff Hobbs:
	
	* generic/tcl.decls: 
	* generic/tclUtf.c: Added Tcl_UniCharIs* functions for control,
	graph, print, and punct classes.

	* generic/tclUtil.c:
	* doc/StrMatch.3: Added Tcl_StringCaseMatch() implementation to
	support case-insensitive globbing.
	
	* doc/string.n: 
	* unix/mkLinks: 
	* tests/string.test: 
	* generic/tclCmdMZ.c: Added additional character class tests,
	added -nocase switch to "string match", changed string first/last
	to use offsets.

1999-05-19    <[e-mail]>

	* generic/tcl.h: Add extern "C" block around entire header file for
	C++ compilers to fix linkage issues.  Submitted by Don Porter and
	Paul Duffin.

	* generic/tclRegexp.c: Fix bug when the regexp cache is empty
	and an empty pattern is used in regexp ( such as {} or "" ).

1999-05-18    <[e-mail]>

	* 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    <[e-mail]>

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

1999-05-14    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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/linsert.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.
