with a recursive mutex that was locked by the current thread, the
function was failing with a success return code.

exit.

set ownership of mutex on second grab after abstime timeout.

a non-cancelable sem_wait() function. This is consistent with the
way that pthread_mutex_timedlock.c does it.
(pthread_mutex_lock): Use ptw32_semwait() instead of sem_wait().
|
|
* pthread_mutex_trylock.c: Should return EBUSY rather than EDEADLK.
* pthread_mutex_destroy.c: Remove redundant ownership test (the
trylock call does this for us); do not destroy a recursively locked
mutex.
|
|
|
|
* pthread_cond_destroy.c (pthread_cond_destroy):
When two different threads exist, and one is attempting to
destroy a condition variable while the other is attempting to
initialize a condition variable that was created with
PTHREAD_COND_INITIALIZER, a deadlock can occur. Shrink
the ptw32_cond_list_lock critical section to fix it.
|
|
|
|
Remove code designed to avoid/prevent spurious wakeup
problems. It is believed that the sem_timedwait() call
is consuming a CV signal that it shouldn't and this is
breaking the avoidance logic.
|
|
unreasonable abstime values - that would result in
unexpected timeout values.
* w32_CancelableWait.c (ptw32_cancelable_wait):
Tighten up return value checking and add comments.

* pthread.h: Conditionally added some #defines from config.h
needed when not building the library. e.g. NEED_ERRNO, NEED_SEM.
(PTW32_DLLPORT): Now only defined if _DLL defined.
(_errno): Compiler directive was incorrectly including prototype.
* sched.h: Conditionally added some #defines from config.h
needed when not building the library.
* semaphore.h: Replace an instance of NEED_SEM that should
have been NEED_ERRNO. This change currently has nil effect.
* GNUmakefile: Correct some recent changes.
* Makefile: Add rule to generate pre-processor output.

exit() rather than pthread_exit(). Add comments to explain
why.
* rwlock2_t.c: New test.
* rwlock3_t.c: New test.
* rwlock4_t.c: New test.
* rwlock5_t.c: New test.
* rwlock6_t.c: New test.
* rwlock6_t2.c: New test.
* rwlock6.c (main): Swap thread and result variables
to correspond to actual thread functions.
* rwlock1.c: Change test description comment to correspond
to the actual test.

critical section to solve deadlock problem.
* pthread.c: Add all remaining C modules.
* pthread.h: Use dllexport/dllimport attributes on functions
to avoid using pthread.def.
* sched.h: Likewise.
* semaphore.h: Likewise.
* GNUmakefile: Add new targets for single translation
unit build to maximise inlining potential; generate
pthread.def automatically.
* Makefile: Likewise, but no longer uses pthread.def.

cancelation point. Deferred cancels will interrupt the

to disable cancelation at the start of a thread's cancelation
run to prevent double cancelation. The main problem
arises if a thread is canceling and then receives a subsequent
async cancel request.
* private.c: Likewise.
* condvar.c: Place pragmas around cleanup_push/pop to turn
off inline optimisation (/Obn where n>0 - MSVC only). Various
optimisation switches in MSVC turn this on, which interferes with
the way that cleanup handlers are run in C++ EH and SEH
code. Application code compiled with inline optimisation must
also wrap cleanup_push/pop blocks with the pragmas, e.g.
#pragma inline_depth(0)
pthread_cleanup_push(...)
...
pthread_cleanup_pop(...)
#pragma inline_depth(8)
* rwlock.c: Likewise.
* mutex.c: Remove attempts to inline some functions.
* signal.c: Modify misleading comment.

for systems that define NEED_SEM (e.g. early WinCE).
* mutex.c (pthread_mutex_timedlock): Return ENOTSUP
for systems that define NEED_SEM since they don't
have sem_trywait().

for the case where abstime has passed already.
Make routines INLINEable since some are called by other
routines in this module.
