|  | * Template.c: Revamp.
        * condvar1.c: Add.
        * condvar2.c: Add.
	* Makefile: Add condvar1 condvar2 tests.
        * exit1.c, exit2.c, exit3.c: Cosmetic changes. | 
|  | * Makefile: Some refinement.
        * *.c: More exhaustive checking through assertions; clean up;
        add some more tests. | 
|  | * Makefile: Now actually runs the tests.
        * tests.h: Define our own assert macro. The Mingw32
        version pops up a dialog but we want to run non-interactively.
        * equal1.c: use assert a little more directly so that it
        prints the actual call statement.
        * exit1.c: Modify to return 0 on success, 1 on failure. | 
|  | * pthread.h (PTHREAD_MUTEX_INITIALIZER): missing braces around
        cs element initialiser.
Bring some tests up-to-date. | 
|  | * README: Update.
	* Makefile: New file. Run all tests automatically. Primitive tests
	are run first; more complex tests are run last.
	* count1.c: New test. Validate the thread count.
	* exit2.c: Perform a simpler test.
	* exit3.c: New test. Replaces exit2.c, since exit2.c needs to
	perform simpler checking first.
	* create1.c: Update to use the new testsuite exiting convention.
	* equal1.c: Likewise.
	* mutex1.c: Likewise.
	* mutex2.c: Likewise.
	* once1.c: Likewise.
	* self2.c: Likewise.

|  | * pthread.h (pthread_exit): The return type of this function is
	void, not int.
	* exit.c (pthread_exit): Do not return 0. | 
|  | * tests/mutex2.c: Test static mutex initialisation.
        * tests/test.h: New. Declares a table mapping error numbers to
        error names. | 
|  | * dll.c (DLLMain): Expand TryEnterCriticalSection support test.
        * mutex.c (pthread_mutex_trylock): The check for
        _pthread_try_enter_critical_section == NULL should have been
        removed long ago. | 
|  | * sync.c (pthread_join): Fix pthread_equal() test.
        * mutex.c (pthread_mutex_trylock): Check mutex != NULL before
        using it. | 
|  |  | 
|  | * misc.c (pthread_equal): Fix inverted result. | 
|  |  | 
|  |  | 
|  | * Makefile.in: Use libpthread32.a as the name of the DLL export
        library instead of pthread.lib.
        * condvar.c (pthread_cond_init): cv could have been used unitialised;
        initialise.
        * create.c (pthread_create): parms could have been used unitialised;
        initialise.
Add "Makefile" for people who don't want to (or can't) run ./configure. | 
|  | It is being added for those not building under Cygwin or similar
environment and who therefore can't run ./configure. | 
|  | * pthread.h (struct pthread_once_t_): Remove redefinition. | 
|  | * pthread.h (struct pthread_once_t_): Replaced.
        * misc.c (pthread_once): Replace with John Bossom's version;
        has lighter weight serialisation; fixes problem of not holding
        competing threads until after the init_routine completes. | 
|  |  | 
|  | * misc.c (CancelableWait): Change C++ exception throw.
        * sync.c (pthread_join): Change FIXME comment - issue resolved. | 
|  |  | 
|  | * configure: Various temporary changes.

        pthreadCancelableWait() call.
Fri Jan 22 14:31:59 1999  Ross Johnson  <rpj@swan.canberra.edu.au>
        * Makefile.in (CFLAGS): Remove -fhandle-exceptions. Not needed
        with egcs. Add -g for debugging.
        * create.c (pthread_create): Replace __stdcall with PT_STDCALL
        macro. This is a hack and must be fixed.

        * private.c (_pthread_callUserDestroyRoutines): Redo conditional
        compilation.
        * misc.c (CancelableWait): C++ version uses 'throw'.
        * cancel.c (pthread_testcancel): Ditto.
        * implement.h (class pthread_exception): Define for C++.
        * pthread.h: Fix C, C++, and Win32 SEH condition compilation
        mayhem around pthread_cleanup_* defines. C++ version now uses John
        Bossom's cleanup handlers.
        (pthread_attr_t): Make 'valid' unsigned.
        Define '_timeb' as 'timeb' for Ming32.
        Define PT_STDCALL as nothing for Mingw32. May be temporary.
        * cancel.c (pthread_testcancel): Cast return value. | 
|  | * pthread.h (PTHREAD_MUTEX_AUTO_CS_NP): New.
        (PTHREAD_MUTEX_FORCE_CS_NP): New. | 
|  | * README: Updated. | 
|  | * pthread.h (pthread_mutexattr_t): Changed to a pointer.
        * mutex.c (pthread_mutex_init): Conditionally create Win32 mutex
        - from John Bossom's implementation.
        (pthread_mutex_destroy): Conditionally close Win32 mutex
        - from John Bossom's implementation.
        (pthread_mutexattr_init): Replaced by John Bossom's version.
        (pthread_mutexattr_destroy): Ditto.
        (pthread_mutexattr_getpshared): New function from John Bossom's
        implementation.
        (pthread_mutexattr_setpshared): New function from John Bossom's
        implementation.
Tue Jan 19 18:27:42 1999  Ross Johnson  <rpj@swan.canberra.edu.au>
        * pthread.h (pthreadCancelableTimedWait): New prototype.
        (pthreadCancelableWait): Remove second argument.
        * misc.c (CancelableWait): New static function is
        pthreadCancelableWait() renamed.
        (pthreadCancelableWait): Now just calls CancelableWait() with
        INFINITE timeout.
        (pthreadCancelableTimedWait): Just calls CancelableWait()
        with passed in timeout.
        * private.c (_pthread_sem_timedwait): 'abstime' arg really is
        absolute time. Calculate relative time to wait from current
        time before passing timeout to new routine
        pthreadCancelableTimedWait().

Tue Jan 19 10:27:39 1999  Ross Johnson  <rpj@ixobrychus.canberra.edu.au>
        * pthread.h (pthread_mutexattr_setforcecs_np): New prototype.
        * mutex.c (pthread_mutexattr_init): Init 'pshared' and 'forcecs'
        attributes to 0.
        (pthread_mutexattr_setforcecs_np): New function (not portable).
        * pthread.h (pthread_mutex_t):
        Add 'mutex' element. Set to NULL in PTHREAD_MUTEX_INITIALIZER.
        The pthread_mutex_*() routines will try to optimise performance
        by choosing either mutexes or critical sections as the basis
        for pthread mutexes for each indevidual mutex.
        (pthread_mutexattr_t_): Add 'forcecs' element.
        Some applications may choose to force use of critical sections
        if they know that:-
             the mutex is PROCESS_PRIVATE and,
                 either the OS supports TryEnterCriticalSection() or
                 pthread_mutex_trylock() will never be called on the mutex.
        This attribute will be setable via a non-portable routine.
        Note: We don't yet support PROCESS_SHARED mutexes, so the
        implementation as it stands will default to Win32 mutexes only if
        the OS doesn't support TryEnterCriticalSection. On Win9x, and early
        versions of NT 'forcecs' will need to be set in order to get
        critical section based mutexes.
Sun Jan 17 12:01:26 1999  Ross Johnson  <rpj@ixobrychus.canberra.edu.au>
        * pthread.h (PTHREAD_MUTEX_INITIALIZER): Init new 'staticinit'
        value to '1' and existing 'valid' value to '1'.
        * global.c (_pthread_mutex_test_init_lock): Add.
        * implement.h (_pthread_mutex_test_init_lock.): Add extern.
        * private.c (_pthread_processInitialize): Init critical section for
        global lock used by _mutex_check_need_init().
        (_pthread_processTerminate): Ditto (:s/Init/Destroy/).
        * dll.c (dllMain): Move call to FreeLibrary() so that it is only
        called once when the process detaches.
        * mutex.c (_mutex_check_need_init): New static function to test
        and init PTHREAD_MUTEX_INITIALIZER mutexes. Provides serialised
        access to the internal state of the uninitialised static mutex.
        Called from pthread_mutex_trylock() and pthread_mutex_lock() which
        do a quick unguarded test to check if _mutex_check_need_init()
        needs to be called. This is safe as the test is conservative
        and is repeated inside the guarded section of
        _mutex_check_need_init(). Thus in all calls except the first
        calls to lock static mutexes, the additional overhead to lock any
        mutex is a single memory fetch and test for zero.
        * pthread.h (pthread_mutex_t_): Add 'staticinit' member. Mutexes
        initialised by PTHREAD_MUTEX_INITIALIZER aren't really initialised
        until the first attempt to lock it. Using the 'valid'
        flag (which flags the mutex as destroyed or not) to record this
        information would be messy. It is possible for a statically
        initialised mutex such as this to be destroyed before ever being
        used.
        * mutex.c (pthread_mutex_trylock): Call _mutex_check_need_init()
        to test/init PTHREAD_MUTEX_INITIALIZER mutexes.
        (pthread_mutex_lock): Ditto.
        (pthread_mutex_unlock): Add check to ensure we don't try to unlock
        an unitialised static mutex.
        (pthread_mutex_destroy): Add check to ensure we don't try to delete
        a critical section that we never created. Allows us to destroy
        a static mutex that has never been locked (and hence initialised).
        (pthread_mutex_init): Set 'staticinit' flag to 0 for the new mutex. | 
|  | * pthread.h (pthreadCancelableTimedWait): New prototype.
        (pthreadCancelableWait): Remove second argument.
        * misc.c (CancelableWait): New static function is
        pthreadCancelableWait() renamed.
        (pthreadCancelableWait): Now just calls CancelableWait() with
        INFINITE timeout.
        (pthreadCancelableTimedWait): Just calls CancelableWait()
        with passed in timeout.
        * private.c (_pthread_sem_timedwait): 'abstime' arg really is
        absolute time. Calculate relative time to wait from current
        time before passing timeout to new routine
        pthreadCancelableTimedWait().
        - Scott Lightner <scott@curriculum.com> | 
|  | * private.c (_pthread_sem_timedwait): Move from semaphore.c.
        * semaphore.c : Remove redundant #includes.
        (_pthread_sem_timedwait): Move to private.c.
        (sem_wait): Add missing abstime arg to pthreadCancelableWait() call.
1999-01-17  Ross Johnson  <rpj@ise.canberra.edu.au>
        * runtest: New script to build and run a test in the tests directory. | 
|  | * pthread.h: Add new 'abstime' arg to pthreadCancelableWait()
	prototype.
	* condvar.c (cond_timedwait): New generalised function called by
	both pthread_cond_wait() and pthread_cond_timedwait(). This is
	essentially pthread_cond_wait() renamed and modified to add the
	'abstime' arg and call the new _pthread_sem_timedwait() instead of
	sem_wait().
	(pthread_cond_wait): Now just calls the internal static
	function cond_timedwait() with an INFINITE wait.
	(pthread_cond_timedwait): Now implemented. Calls the internal
	static function cond_timedwait().
	* implement.h (_pthread_sem_timedwait): New internal function
	prototype.
	* misc.c (pthreadCancelableWait): Added new 'abstime' argument
	to allow shorter than INFINITE wait.
	* semaphore.c (_pthread_sem_timedwait): New function for internal
	use.  This is essentially sem_wait() modified to add the
        'abstime' arg and call the modified (see above)
        pthreadCancelableWait(). | 
|  | * cleanup.c: Correct _cplusplus to __cplusplus wherever used.
        * Makefile.in: Add CC=g++ and add -fhandle-exceptions to CFLAGS.
        The derived Makefile will compile all units of the package as C++
        so that those which include try/catch exception handling should work
        properly. The package should compile ok if CC=gcc, however, exception
        handling will not be included and thus thread cancellation, for
        example, will not work.
        * cleanup.c (_pthread_pop_cleanup): Add #warning to compile this
        file as C++ if using a cygwin32 environment. Perhaps the whole package
        should be compiled using g++ under cygwin.
        * private.c (_pthread_threadStart): Change #error directive
        into #warning and bracket for __CYGWIN__ and derivative compilers. | 
|  | * build.bat: Delete old binaries before compiling/linking.
Tue Jan 12 09:58:38 1999  Ross Johnson  <rpj@ixobrychus.canberra.edu.au>
        * dll.c: The Microsoft compiler pragmas probably are more
        appropriately protected by _MSC_VER than by _WIN32.
        - Tor Lillqvist <tml@iki.fi>.
        * condvar.c (pthread_cond_timedwait): Fix function description
        comments.
        * pthread.h: Define ETIMEDOUT. This should be returned by
        pthread_cond_timedwait which is not implemented yet as of
        snapshot-1999-01-04-1305. It was implemented in the older version.
        The Microsoft compiler pragmas probably are more appropriately
        protected by _MSC_VER than by _WIN32.
        - Tor Lillqvist <tml@iki.fi>.
        * pthread.def: pthread_mutex_destroy was missing from the def file
        - Tor Lillqvist <tml@iki.fi>.
        * condvar.c (pthread_cond_broadcast): Ensure we only wait on threads
        if there were any waiting on the condition.
        I think pthread_cond_broadcast should do the WaitForSingleObject
        only if cv->waiters > 0? Otherwise it seems to hang, at least in the
        testg thread program from glib.
        - Tor Lillqvist <tml@iki.fi>.
        * semaphore.c (sem_post): Correct typo in comment.
Mon Jan 11 20:33:19 1999  Ross Johnson  <rpj@ixobrychus.canberra.edu.au>
        * pthread.h: Re-arrange conditional compile of pthread_cleanup-*
        macros.
        * cleanup.c (_pthread_push_cleanup): Provide conditional
        compile of cleanup->prev. | 
|  | * condvar.c (pthread_cond_init): Invert logic when testing the
        return value from calloc(). | 
|  | * implement.h: Compile-time switch for CYGWIN derived environments
        to use CreateThread instead of _beginthreadex. Ditto for ExitThread.
        Patch provided by Anders Norlander  <anorland@hem2.passagen.se>. | 
|  | now use exception handling to implement thread cancellation. The MSC compiler
appears to know about __try/__except blocks, but gcc (ie. the GNU ANSI C
compiler) doesn't know about the equivalent C++ try/catch blocks. This should
not be a problem since gcc and g++ are nearly always available together. Some
file names may need to change in the CVS repository however.
Tue Jan  5 16:33:04 1999  Ross Johnson  <rpj@swan.canberra.edu.au>
        * cleanup.c (_pthread_pop_cleanup): Add C++ version of __try/__except
        block. Move trailing "}" out of #ifdef _WIN32 block left there by
        (my) mistake.
        * private.c: Remove #include <errno.h> which is included by pthread.h. | 
|  | This will be tagged as snapshot-1999-01-04-1305 | 
|  | * README: Update info about subscribing to the mailing list. | 
|  | Q 1     How do I get pthreads-win32 to link under Cygwin32 or Mingw32? | 
|  | * dll.c (PthreadsEntryPoint): Cast return value of GetProcAddress
	to resolve compile warning from MSVC. | 
|  | * buildlib.bat: Fix args to CL when building the .DLL
        * cleanup.c (_pthread_destructor_run_all): Fix TSD key management.
        This is a tidy-up before TSD and Thread management is completely
        replaced by John Bossom's much more elegant code.
        * tsd.c (pthread_key_create): Fix TSD key management.
        * global.c (_pthread_key_virgin_next): Initialise.
        * build.bat: New DOS script to compile and link a pthreads app
        using Microsoft's CL compiler linker.
        * buildlib.bat: New DOS script to compile all the object files
        and create pthread.lib and pthread.dll using Microsoft's CL
        compiler linker. | 
|  | * build.bat: New DOS script to compile and link a pthreads app

|  | * README: Correct cygwin32 compatibility statement. | 
|  | that hadn't been checked in. Those are to finish off the original TSD management
scheme which will now start to be replaced by John Bossom's implementation.
Anders' description of his changes:-
Fixes the problem with
`TryEnterCriticalSection' on w95 systems. Instead
of directly calling `TryEnterCriticalSection' it
tries to get a pointer at DLL startup and only calls
the function if it exists. See ChangeLog for things
changed.
1998-12-05  Anders Norlander  <anorland@hem2.passagen.se>
	* implement.h (_pthread_try_enter_critical_section): New extern
	* dll.c (_pthread_try_enter_critical_section): New pointer to
	TryEnterCriticalSection if it exists; otherwise NULL.
	* dll.c (PthreadsEntryPoint):
	Initialize _pthread_try_enter_critical_section at startup
	and release kernel32 handle when DLL is being unloaded.
	* mutex.c (pthread_mutex_trylock): Replaced check for NT with
	a check if _pthread_try_enter_critical_section is valid
	pointer to a function. Call _pthread_try_enter_critical_section
	instead of TryEnterCriticalSection to avoid errors on Win95.
Sun Nov 15 21:24:06 1998  Ross Johnson  <rpj@ixobrychus.canberra.edu.au>
	* cleanup.c (_pthread_destructor_run_all): Declare missing void * arg.

	* cleanup.c (_pthread_handler_push): Fixed bug appending new
	handler to list reported by Peter Slacik
	<Peter.Slacik@leibinger.freinet.de>.

	"new_handler".
Sat Oct 24 18:34:59 1998  Ross Johnson  <rpj@ixobrychus.canberra.edu.au>
	* global.c: Add TSD key management array and index declarations.
	* implement.h: Ditto for externs.

	* private.c (_pthread_delete_thread): Add call to
	_pthread_destructor_run_all() to clean up the threads keys.
	* cleanup.c (_pthread_destructor_run_all): Check for no more dirty
	keys to run destructors on. Assume that the destructor call always
	succeeds and set the key value to NULL. | 
|  | * condvar.c (cond_wait): Fix semantic error. Test for equality
