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.

1999-11-18  Jeff Hobbs  <hobbs@scriptics.com>

	* 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

	* generic/tclScan.c: finished support for inline scan by

	supporting XPG identifiers.

1999-11-17 Brent Welch <welch@scriptics.com>

	* 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

	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

	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

	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.

	external, but used the unconverted version.

	* mac/tclMacFCmd.c: Fix a merge error in the bug fix for [Bug: 2869]
