tcl是工具命令语言

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

1999-05-03    <[e-mail]>

	* 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    <[e-mail]>
	
	* Changed version to 8.1.1.
	
1999-04-30    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

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

1999-04-23    <[e-mail]>

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

1999-04-23    <[e-mail]>

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

1999-04-22    <[e-mail]>

	* 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  <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* Merged 8.1 back into the main trunk

1999-04-13    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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    <[e-mail]>

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

	* tests/httpold.test: 
	* tests/if.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/tclCmdMZ.c: 
	* generic/tclInt.h: 
	* 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    <[e-mail]>

	* 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.

1999-04-01    <[e-mail]>

	* generic/tcl.decls:
	* generic/tcl.h:
	* generic/tclBasic.c:
	* generic/tclDecls.h:
	* generic/StubInit.c:
	* 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    <[e-mail]>

	* 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    <[e-mail]>

	* 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.
