	* 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

	TclpMatchFilesTypes, extended TclGlob and TclDoGlob and added
	GlobTypeData structure. [Bug: 2363]

1999-12-10  Jeff Hobbs  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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 <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	cases.

1999-11-19  Jeff Hobbs  <[e-mail]>

1999-11-18  Jeff Hobbs  <[e-mail]>

	* 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/glob.n: added note about ..../ glob behavior on Win9*
	* doc/tcltest.n: fixed minor example errors [Bug: 3551]

1999-11-17 Brent Welch <[e-mail]>
	* 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  <[e-mail]>

	* 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 <[e-mail]>
	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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
