1999-05-21    <redman@scriptics.com>

	* 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    <redman@scriptics.com>

	* 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    <stanton@scriptics.com>

	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    <redman@scriptics.com>

	* 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    <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/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.

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/lindex.test:
	* tests/linsert.test: 
	* tests/lrange.test: 
	* tests/lreplace.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>

	* 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

	* tools/genStubs.tcl:
	* unix/Makefile.in:
	* 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.
	[Bug: 998, 1273, 1573, 1593]

1999-03-29    <stanton@scriptics.com>

	* generic/tclIntDecls.h:
	* generic/tclPlatDecls.h:
	* generic/tclIntPlatDecls.h: Removed the stub functions and
	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>

	* win/makefile.bc: Removed makefile for Borland compiler, no
	longer supported.

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

	* win/tclWinSerial.c:
	* win/tclWinConsole.c:
	* win/tclWinPipe.c: Don't close the Win32 handle for a channel if
	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]
	
	* library/encoding/big5.enc:
	* library/encoding/gb2312.enc:
	* tools/encoding/big5.enc:
	* 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]

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

	* generic/tclAlloc.c:
	* generic/tclEncoding.c:
	* generic/tclProc.c:
	* unix/tclUnixTime.c:
	* 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.

1999-03-17    <stanton@GASPODE>

	* win/README.binary: 
	* win/README: 
	* unix/configure.in: 
	* generic/tcl.h: 
	* README: Updated version to 8.1b3.

1999-03-14    <stanton@GASPODE>

	* 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/tclIntDecls.h: 
	* generic/tclIntPlatDecls.h: 
	* generic/tclIntPlatStubs.c: 
	* generic/tclIntStubs.c: 
	* generic/tclPlatDecls.h: 
	* generic/tclPlatStubs.c: 
	* generic/tclStubInit.c: 
	* generic/tclStubs.c: Fixed bad eol characters.
	
	* 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/tclConfig.sh.in:
	* unix/dltest/Makefile.in:
	* unix/dltest/configure.in:
	* unix/dltest/pkga.c:
	* unix/dltest/pkgb.c:
	* unix/dltest/pkgc.c:
	* unix/dltest/pkgd.c:
	* unix/dltest/pkge.c:
	* unix/dltest/pkgf.c: Changed package tests to build against the
	stubs library.

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.

	* generic/tclInt.h:
	* generic/regc_color.c: 
	* generic/regcomp.c:
	* generic/tclCmdIL.c:
	* generic/tclCmdAH.c:
	* generic/tclIOCmd.c:
	* generic/tclParse.c:
	* generic/tclStringObj.c:
	* unix/tclUnixNotfy.c: Cleaned up various compiler warnings,
	eliminated UCHAR bugs.
	
	* unix/tclUnixNotfy.c:
	* unix/tclUnixThrd.c:
	* generic/tclThreadTest.c:
	* mac/tclMacThrd.c: Changed TclpCondition*() to Tcl_Condition*().
	
	* INTEGRATED PATCHES FROM 8.0.6:

	* generic/tcl.decls:
	* generic/tcl.h:
	* generic/tclBasic.c: 
	* generic/tclDecls.h:
	* generic/tclInt.decls:
	* generic/tclInt.h:

	* tools/genStubs.tcl:
	* unix/configure.in:
	* unix/Makefile.in:
	* unix/tclConfig.sh.in:
	* 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: 
	* doc/PkgRequire.3: 
	* doc/SetResult.3: 
	* doc/StringObj.3: 
	* generic/tcl.h:
	* generic/tclBasic.c: 
	* generic/tclPanic.c:
	* generic/tclStringObj.c:
	* 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).

1999-02-11    <stanton@GASPODE>

	* README: 
	* generic/tcl.h: 
	* win/README.binary: 
	* win/README: 
	* unix/configure.in: 
	* mac/README: Updated version numbers to 8.1b2.

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/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.

	* 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]

	* 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
