* misc.c (CancelableWait): Ensure cancelEvent handle is the lowest indexed element in the handles array. Enhance test for abandoned objects. * pthread.h (PTHREAD_MUTEX_INITIALIZER): Trailing elements not initialised are set to zero by the compiler. This avoids the problem of initialising the opaque critical section element in it. (PTHREAD_COND_INITIALIZER): Ditto. * semaphore.c (_pthread_sem_timedwait): Check sem == NULL earlier. Sun Mar 7 12:31:14 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * condvar.c (pthread_cond_init): set semaphore initial value to 0, not 1. cond_timedwait was returning signaled immediately. * misc.c (CancelableWait): Place the cancel event handle first in the handle table for WaitForMultipleObjects. This ensures that the cancel event is recognised and acted apon if both objects happen to be signaled together. * private.c (_pthread_cond_test_init_lock): Initialise and destroy. * implement.h (_pthread_cond_test_init_lock): Add extern. * global.c (_pthread_cond_test_init_lock): Add declaration. * condvar.c (pthread_cond_destroy): check for valid initialised CV; flag destroyed CVs as invalid. (pthread_cond_init): pthread_cond_t is no longer just a pointer. This is because PTHREAD_COND_INITIALIZER needs state info to reside in pthread_cond_t so that it can initialise on first use. Will work on making pthread_cond_t (and other objects like it) opaque again, if possible, later. (cond_timedwait): add check for statically initialisation of CV; initialise on first use. (pthread_cond_signal): check for valid CV. (pthread_cond_broadcast): check for valid CV. (_cond_check_need_init): Add. * pthread.h (PTHREAD_COND_INITIALIZER): Fix. (pthread_cond_t): no longer a pointer to pthread_cond_t_. (pthread_cond_t_): add 'staticinit' and 'valid' elements. tests/ChangeLog Sun Mar 7 10:41:52 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * Makefile (condvar3, condvar4): Add tests. * condvar4.c (General): Reduce to simple test case; prerequisite is condvar3.c; add description. * condvar3.c (General): Reduce to simple test case; prerequisite is condvar2.c; add description. * condvar2.c (General): Reduce to simple test case; prerequisite is condvar1.c; add description. * condvar1.c (General): Reduce to simple test case; add description. * Template.c (Comments): Add generic test detail.

* 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.
1999-02-211999-02-23 Ross Johnson <rpj@ise.canberra.edu.au>rpj
* 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.
1999-02-21Sun Feb 21 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* 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. * self3.c: Likewise. * tsd1.c: Likewise.

* 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(). - Scott Lightner <scott@curriculum.com> 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.

* global.c (PTHREAD_MUTEX_INITIALIZER): Move to pthread.h. * pthread.h (PTHREAD_MUTEX_INITIALIZER): Define. (pthread_mutex_t): Reimplement as a struct containing a valid flag. If the flag is ever down upon entry to a mutex operation, we call pthread_mutex_create() to initialise the object. This fixes the problem of how to handle statically initialised objects that can't call InitializeCriticalSection() due to their context. * mutex.c (pthread_mutex_init): Set valid flag. (pthread_mutex_destroy): Clear valid flag. (pthread_mutex_lock): Check and handle the valid flag. (pthread_mutex_unlock): Likewise. (pthread_mutex_trylock): Likewise. * tests/mutex3.c: New file; test for the static initialisation macro. Passes.
