	*** 8.4.15 TAGGED FOR RELEASE ***

	* generic/tclIO.c:	Backport memleak fix in TclFinalizeIOSubsystem.

2007-05-17  Don Porter  <dgp@users.sourceforge.net>

	* tests/fCmd.test:	Backport the notNetworkFilesystem constraint.

2007-05-15  Don Porter  <dgp@users.sourceforge.net>

	* library/reg/pkgIndex.tcl:	for [1682211] bug fix.

2007-05-10  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.h:     TclFinalizeThreadAlloc() is always defined,

	so make sure it is also always declared.

	[Tcl Bug 1706140]

	* generic/tclCmdMZ.c (Trace*Proc):	Update Tcl_VarTraceProcs so

	* generic/tclLink.c (LinkTraceProc):    that they call

	* generic/tclUtil.c (TclPrecTraceProc): Tcl_InterpDeleted() for

	themselves, and do not rely on (frequently buggy) setting of the

	TCL_INTERP_DESTROYED flag by the trace core.

	* generic/tclVar.c:     Update callers of CallVarTraces to not

	pass in the TCL_INTERP_DESTROYED flag.  Also apply filters so that

	public routines only pass documented flag values down to lower level

	routines.

	* generic/tclVar.c (CallVarTraces):        The setting of the

	TCL_INTERP_DESTROYED flag is now done entirely within the

	CallVarTraces routine, the only place it can be done right.

2007-04-30  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in: add 'tclsh' dependency to install targets that rely

	on tclsh, fixes parallel 'make install' from empty build dir.

2007-04-29  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixFCmd.c: add workaround for crashing bug in fts_open()

	* macosx/tclMacOSXNotify.c:

	* unix/tclLoadDyld.c:

	* macosx/Makefile:		fix/add copyright and license refs.

	* macosx/tclMacOSXBundle.c:

	* macosx/Tcl-Info.plist.in:

	* unix/Makefile.in (dist): copy license.terms to dist macosx dir.

	* generic/tclInt.decls:      Yet another round of attempting

	* generic/tclInt.h:          to get the correct type signature

	* unix/tclUnixPort.h:        for TclpLocaltime and TclpGmtime.

	* unix/tclUnixTime.c:        CONST TclpTime_t is a 'time_t *CONST'

	* win/tclWinTime.c:          and not a 'CONST time_t*' [Bug 1677275]

	* generic/tclIntDecls.h:     

	* generic/tclIntPlatDecls.h: Regenerated.

2007-03-24  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* win/tclWinThrd.c: Thread exit handler marks the current 

	thread as un-initialized. This allows exit handlers that

	are registered later to re-initialize this subsystem in 

	case they need to use some sync primitives (cond variables)

	from this file again. 

2007-03-19  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclEvent.c (Tcl_CreateThread):	Replaced some calls to

	* generic/tclPkg.c (CheckVersion):	Tcl_Alloc() with calls to

	* unix/tclUnixTime.c (SetTZIfNecessary):	ckalloc(), which better

	* win/tclAppInit.c (setargv):	supports memory debugging.

2007-03-17  Kevin Kenny  <kennykb@acm.org>

	* win/tclWinReg.c (GetKeyNames): Size the buffer for enumerating

	above bug.

2007-03-13  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c (INST_FOREACH_STEP4):	Re-fetch pointers for

	* tests/foreach.test (foreach-10.1):	the value list each iteration

	of the loop as defense against shimmers.  [Bug 1671087]

	* generic/tclVar.c (TclArraySet):	Re-fetch pointers for the list

	* tests/var.test (var-17.1):	argument of [array set] each time

	through the loop as defense against possible shimmer issues.

	[Bug 1669489].

2007-03-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompCmds.c (TclCompileForeachCmd): Prevent an unexpected

	* tests/foreach.test (foreach-9.1):		infinite loop when the

2007-02-22  Andreas Kupries  <andreask@activestate.com>

	* tests/pkg.test: Added tests for the case of an alpha package

	  satisfying a require for the regular package, demonstrating a

	  corner case specified in TIP#280. More notes in the comments to

	  the test.

2007-02-20  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n:	Typo fix.  [Bug 1663539]

2007-02-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclIOUtil.c (Tcl_FSEvalFile): safe incr of objPtr ref.

	* generic/tclEncoding.c (EscapeFromUtfProc): Applied patch

	  supplied by Mo DeJong to fix [Bug 1516109]. Backport from Tcl

	  8.5. Mo's description: Clear the TCL_ENCODING_END flag when end

	  bytes are written. This fix keep this method from writing escape

	  bytes for an encoding like iso2022-jp multiple times when the

	  escape byte overlap with the end of the IO buffer.

	* tests/io.test: Add test case for escape byte overlap case.

2007-02-04  Daniel Steffen  <das@users.sourceforge.net>

2007-01-25  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4:       integrate CPPFLAGS into CFLAGS as late as possible

	* unix/configure.in: and move (rather than duplicate) -isysroot flags

	from CFLAGS to CPPFLAGS to avoid errors about multiple -isysroot flags

	from some older gcc builds.

	* unix/configure: autoconf-2.13

2007-01-22  Andreas Kupries <andreask@activestate.com>

	* compat/memcmp.c (memcmp): Fixed the VOID / CONST typo introduced

	  by the last checkin.

2007-01-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* compat/memcmp.c (memcmp): Reworked so that arithmetic is never

	performed upon void pointers, since that is illegal. [Bug 1631017]

2006-01-19  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/tclMacOSXNotify.c: accommodate changes to prototypes of

	OSSpinLock(Un)Lock API.

	* tests/env.test: add extra system env vars that need to be preserved

	on some Mac OS X versions for testsuite to work.

	* unix/tcl.m4: ensure CPPFLAGS env var is used when set. [Bug 1586861]

	(Darwin): add -isysroot and -mmacosx-version-min flags to CPPFLAGS when

	present in CFLAGS to avoid discrepancies between what headers configure

	sees during preprocessing tests and compiling tests.

2006-12-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/string.n: Fix example. [Bug 1615277]

2006-12-05  Andreas Kupries <andreask@activestate.com>

	* tests/pkg.test:   Backport to 8.4 (Don Porter's work):

	* generic/tclPkg.c: When no requirements are supplied to a [package

	require $pkg] and [package unknown] is invoked to find a satisfying

	package, pass the requirement argument "0-" (which means all versions

	are acceptable). This permits a registered [package unknown] command

	to call [package vsatisfies $testVersion {*}$args] without any special

	handling of the empty $args case. This fixes/avoids a bug in

	[::tcl::tm::UnknownHandler] that was causing old TM versions to be

	provided in preference to newer TM versions. Thanks to Julian Noble

	for discovering the issue.
