already running (e.g. if Tcl_WaitForEvent was called recursively),
re-run it in a custom run loop mode containing only the source for the
notifier thread, otherwise wakeups from other sources added to the
common run loop modes might get lost; sync panic msg changes from HEAD.
* unix/tclUnixNotfy.c (Tcl_WaitForEvent): on 64-bit Darwin,
pthread_cond_timedwait() appears to have a bug that causes it to wait
forever when passed an absolute time which has already been exceeded by
the system time; as a workaround, when given a very brief timeout, just
do a poll on that platform. [Bug 1457797]

add CFLAGS to SHLIB_LD to support passing -isysroot in env(CFLAGS) to
configure (flag can't be present twice, so can't be in both CFLAGS and
LDFLAGS during configure), don't use -prebind when deploying on 10.4,
define TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING (rdar://3171542).
(SC_ENABLE_LANGINFO, SC_TIME_HANDLER): add/fix caching, fix obsolete
autoconf macros. Sync with tk/unix/tcl.m4, sync whitespace with HEAD.
* unix/configure.in: fix obsolete autoconf macros, sync gratuitous
formatting/ordering differences with tk/unix/configure.in.
* unix/Makefile.in: add CFLAGS to tclsh/tcltest link to make executable
linking the same as during configure (needed to avoid loosing any linker
relevant flags in CFLAGS, in particular flags that can't be in LDFLAGS).
Avoid concurrent linking of tclsh and compiling of tclTestInit.o or
xtTestInit.o during parallel make.
(checkstubs, checkdoc, checkexports): dependency and Darwin fixes
* unix/tclLoadDyld.c (TclpDlopen): use NSADDIMAGE_OPTION_WITH_SEARCHING
on second NSAddImage only. [Bug 1204237]
(TclGuessPackageName): should not be MODULE_SCOPE.
(TclpLoadMemory): ppc64 and endian (i386) fixes, add support for loading
universal (fat) bundles from memory.
* unix/tclUnixPort.h:
* unix/tclUnixFCmd.c: add support for new Tiger copyfile() API to enable
copying of xattrs & ACLs by [file copy].
* generic/tcl.h: add Darwin specifc configure overrides for TCL_WIDE
defines to support fat compiles of ppc and ppc64 at the same time,
(replaces Darwin CVS fix by emoy, rdar://3693001).
add/correct location of version numbers in macosx files.
* generic/tclInt.h: clarify fat compile comment.
* unix/tclUnixPort.h: add Darwin specifc configure overrides to support
fat compiles, where configure runs only once for multiple architectures
(replaces Darwin CVS fix by emoy, rdar://3693001).
* macosx/tclMacOSXBundle.c:
* macosx/tclMacOSXNotify.c:
* unix/tclUnixNotfy.c:
* unix/tclUnixPort.h: fix #include order to support compile time
override of HAVE_COREFOUNDATION in tclUnixPort.h when building for ppc64
* macosx/Tcl.pbproj/default.pbxuser (new file):
* macosx/Tcl.pbproj/jingham.pbxuser:
* macosx/Tcl.pbproj/project.pbxproj: sync with HEAD.
* macosx/README: clarification/cleanup, sync with HEAD, document
universal (fat) builds via CFLAGS (i.e. all of ppc ppc64 i386 at once).
* macosx/Makefile: add support for reusing configure cache, build target
fixes, remove GENERIC_FLAGS override now handled by tcl.m4.
* generic/tclIOUtil.c:
* generic/tclRegexp.c:
* generic/tclVar.c: declare globals used only in own file as static
(sync with HEAD).
* generic/rege_dfa.c (getvacant):
* generic/regexec.c (cfind):
* generic/tclCompExpr.c (CompileSubExpr):
* unix/tclUnixChan.c (TclUnixWaitForFile): initialise variables to
silence gcc 4 warnings.
* generic/regguts.h: only #define NDEBUG if not already #defined.
* macosx/tclMacOSXNotify.c: sync whitespace & comments with HEAD

* unix/tclUnixInit.c:
* unix/tcl.m4 (Darwin): made use of CoreFoundation API configurable
and added test of CoreFoundation availablility to allow building on
ppc64, replaced HAVE_CFBUNDLE by HAVE_COREFOUNDATION; test for
availability of Tiger or later OSSpinLockLock API.
* unix/tclUnixNotfy.c:
* unix/Makefile.in:
* macosx/tclMacOSXNotify.c (new file): when CoreFoundation is
available, use new CFRunLoop based notifier: allows easy integration
with other event loops on Mac OS X, in particular the TkAqua Carbon
event loop is now integrated via a standard tcl event source (instead
of TkAqua upon loading having to finalize the exsting notifier and
replace it with its custom version). [Patch 1202052]
* tests/unixNotfy.test: don't run unthreaded tests on Darwin
since notifier may be using threads even in unthreaded core.
* unix/tclUnixPort.h:
* unix/tcl.m4 (Darwin): test for thread-unsafe realpath durning
configure, as Darwin 7 and later realpath is threadsafe.
* macosx/tclMacOSXBundle.c:
* unix/tclLoadDyld.c:
* unix/tclUnixInit.c: fixed gcc 4.0 warnings.
* unix/configure: autoconf-2.13

build on Mac OS X 10.1 again.
* generic/tclNotify.c (TclFinalizeNotifier): fixed notifier not being
finalized in unthreaded core (was testing for notifier initialization in
current thread by checking thread id != 0 but thread id is always 0 in
untreaded core).
* unix/tclUnixNotfy.c (Tcl_WaitForEvent): sync with HEAD: only declare
and use timeout var in unthreaded core.
* unix/Makefile.in: added @PLAT_SRCS@ to SRCS and split out NOTIFY_SRCS
from UNIX_SRCS for parity with UNIX_OBJS & NOTIFY_OBJS.
* unix/configure.in: only run check for broken strstr implementation if
AC_REPLACE_FUNCS(strstr) hasn't already determined that strstr is
unavailable, otherwise compat/strstr.o will be used twice (resulting in
duplicate symbol link errors on Mac OS X 10.1)
* unix/tcl.m4 (Darwin): added configure checks for recently added linker
flags -single_module and -search_paths_first to allow building with
older tools (and on Mac OS X 10.1), use -single_module in SHLIB_LD and
not just T{CL,K}_SHLIB_LD_EXTRAS, added unexporting from Tk of symbols
from libtclstub to avoid duplicate symbol warnings, added PLAT_SRCS
definition for Mac OS X.
(SC_MISSING_POSIX_HEADERS): added caching of dirent.h check.
(SC_TCL_64BIT_FLAGS): fixed 'checking for off64_t' message output.
* unix/configure: autoconf-2.13

3-argument readdir_r [Bug 1001325].
* unix/configure: Regenerated.
* unix/tclUnixNotfy.c: Corrected all uses of 'select' to
manage their masks using the FD_CLR, FD_ISSET, FD_SET, and
FD_ZERO macros rather than bit-whacking that failed under
Solaris-Sparc-64. [Bug 1071807]

* generic/tclStubInit.c (tclOriginalNotifier):
* mac/tclMacNotify.c (Tcl_SetTimer,Tcl_WaitForEvent):
* unix/tclUnixNotfy.c (Tcl_SetTimer,Tcl_WaitForEvent,
Tcl_CreateFileHandler,Tcl_DeleteFileHandler):
* win/tclWinNotify.c (Tcl_SetTimer,Tcl_WaitForEvent): Some linkers
apparently use a different representation for a pointer to a function
within the same compilation unit and a pointer to a function in a
different compilation unit. This causes checks like those in the
original notifier procedures to fall into infinite loops. The fix
is to store pointers to the original notifier procedures in a struct
defined in the same compilation unit as the stubs tables, and compare
against those values. [Bug 707174]

* generic/tcl.decls: added new macosx specific entry to stubs table.
* tools/genStubs.tcl: added generation of platform guards for
macosx. This is a little more complex than it seems, because MacOS
X IS "unix" plus a little bit, for the purposes of Tcl. BUT
unfortunately, Tk uses "unix" to mean X11. So added platform keys
for macosx (the little added to "unix"), "aqua" and "x11" to
distinguish these for Tk.
* generic/tcl.h: added a #ifnded RESOURCE_INCLUDED so that tcl.h
can be passed to the resource compiler.
* generic/tcl.h:
* generic/tclNotify.c: added a few Notifier procs, to be able to
modify more bits of the Tcl notifier dynamically. Required to get
Mac OS X Tk to live on top of the Tcl Unix threaded notifier.
Changes the size of the Tcl_NotifierProcs structure, but doesn't
move any elements around.
* unix/tclUnixNotfy.c: moved the call to Tcl_ConditionNotify till
AFTER we are done mucking with the pointer swap. Fixes cases where
the thread waiting on the condition wakes & accesses the
waitingListPtr before it gets reset, causing a hang.
* library/auto.tcl (tcl_findLibrary): added checking the
directories in the tcl_pkgPath for library files on macosx to
enable support of the standard Mac OSX library locations
* unix/Makefile.in:
* unix/configure.in:
* unix/tcl.m4: added MAC_OSX_DIR. Added PLAT_OBJS to the OBJS:
there are some MacOS X specific files now for Tcl, and when I get
he resource & applescript stuff ported over, and restore support
for FindFiles, etc, there will be a few more.
Added LD_LIBRARY_PATH_VAR configure variable to avoid having to set
all possible LD_LIBRARY_PATH analogues on all platforms.
LD_LIBRARY_PATH_VAR is "LD_LIBRARY_PATH" by default, "LIBPATH" on
AIX, "SHLIB_PATH" on HPUX and "DYLD_LIBRARY_PATH" on Mac OSX.
Added configure option to package Tcl as a framework on Mac OSX.
* macosx/tclMacOSXBundle.c (new): support for finding Tcl extension
packaged as 'bundles' in the standard Mac OSX library locations.
* unix/tclUnixInit.c: added support for findig the tcl script
library inside Tcl packaged as a framework on Mac OSX.
* macosx/Tcl.pbproj/jingham.pbxuser (new):
* macosx/Tcl.pbproj/project.pbxproj (new): project for Apple's
ProjectBuilder IDE.
* macosx/Makefile (new): simple makefile for building the project
from the command line via the ProjectBuilder tool 'pbxbuild'.
* unix/configure:
* generic/tclStubInit.c:
* generic/tclPlatDecls.h: regen

* Overall change: Definition of a public API for the creation of
new threads.
* generic/tclInt.h (line 1802f): Removed the definition of
'TclpThreadCreate'. (line 793f) Removed the definition of
'Tcl_ThreadCreateProc'.
* generic/tcl.h (line 388f): Readded the definition of
'Tcl_ThreadCreateProc'. Added Win32 stuff send in by David
Graveraux <davygrvy@bigfoot.com> to that too (__stdcall,
...). Added macros for the default stacksize and allowed flags.
* generic/tcl.decls (line 1356f): Added definition of
'Tcl_CreateThread', slot 393 of the stub table. Two new
arguments in the public API, for stacksize and flags.
* win/tclWinThrd.c:
* mac/tclMacThrd.c: Renamed TclpThreadCreate to Tcl_CreateThread,
added handling of the stacksize. Flags are currently ignored.
* unix/tclUnixThrd.c: See above, but handles joinable
flag. Ignores the specified stacksize if the macro
HAVE_PTHREAD_ATTR_SETSTACKSIZE is not defined.
* generic/tclThreadTest.c (line 363): See below.
* unix/tclUnixNotfy.c (line 210): Adapted to the changes
above. Uses default stacksize and no flags now.
* unic/tcl.m4 (line 382f): Added a check for
'pthread_attr_setstacksize' to detect platforms not implementing
this feature of pthreads. If it is implemented, configure will
define the macro HAVE_PTHREAD_ATTR_SETSTACKSIZE (See
unix/tclUnixThrd.c too).
* doc/Thread.3: Added Tcl_CreateThread and its arguments to the
list of described functions. Removed stuff about not providing a
public C-API for thread-creation.

Tcl_MutexFinalize.
* unix/tclUnixNotfy.c:
* generic/tclThreadTest.c: Changed usages of TclFinalizeCondition to
Tcl_ConditionFinalize.
* generic/tcl.h: Added empty macros for Tcl_MutexFinalize and
Tcl_ConditionFinalize, to be used when the core is compiled
without threads.
* doc/Thread.3: Added description the new API's.
