2002-02-23 * pthread_cond_destroy.c: Expand the time changerpj
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.

* mutex.c (pthread_mutex_timedlock): New function suggested by Alexander Terekhov. The logic required to implement this properly came from Alexander, with some collaboration with Thomas Pfaff. (pthread_mutex_unlock): Wrap the waiters check and sema post in a critical section to prevent a race with pthread_mutex_timedlock. (ptw32_timed_semwait): New function; returns a special result if the absolute timeout parameter represents a time already passed when called; used by pthread_mutex_timedwait(). Have deliberately not reused the name "ptw32_sem_timedwait" because they are not the same routine. * condvar.c (ptw32_cond_timedwait): Use the new sem_timedwait() instead of ptw32_sem_timedwait(), which now has a different function. See previous. * implement.h: Remove prototype for ptw32_sem_timedwait. See next. (pthread_mutex_t_): Add critical section element for access to lock_idx during mutex post-timeout processing. * semaphore.h (sem_timedwait): See next. * semaphore.c (sem_timedwait): See next. * private.c (ptw32_sem_timedwait): Move to semaphore.c and rename as sem_timedwait(). 2002-01-18 Ross Johnson <rpj@special.ise.canberra.edu.au> * sync.c (pthread_join): Was getting the exit code from the calling thread rather than the joined thread if defined(__MINGW32__) && !defined(__MSVCRT__). 2002-01-15 Ross Johnson <rpj@special.ise.canberra.edu.au> * pthread.h: Unless the build explicitly defines __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then the build defaults to __CLEANUP_C style cleanup. This style uses setjmp/longjmp in the cancelation and thread exit implementations and therefore won't do stack unwinding if linked to applications that have it (e.g. C++ apps). This is currently consistent with most/all commercial Unix POSIX threads implementations. * spin.c (pthread_spin_init): Edit renamed function call. * nonportable.c (pthread_num_processors_np): New. (pthread_getprocessors_np): Renamed to ptw32_getprocessors and moved to private.c. * private.c (pthread_getprocessors): Moved here from nonportable.c. * pthread.def (pthread_getprocessors_np): Removed from export list. * rwlock.c (pthread_rwlockattr_init): New. (pthread_rwlockattr_destroy): New. (pthread_rwlockattr_getpshared): New. (pthread_rwlockattr_setpshared): New.
2001-12-18Include an interim complete Copyright notice in each source file;rpj
Remove unused autoconf files; Add the file COPYING, which describes the pthread-win32 license relative to the FSF LGPL.
2001-07-08Barriers fixed and tested more extensively.rpj
* barrier.c: Fix several bugs in all routines. Now passes tests/barrier5.c which is fairly rigorous. There is still a non-optimal work-around for a race condition between the barrier breeched event signal and event wait. Basically the last (signalling) thread to hit the barrier yields to allow any other threads, which may have lost the race, to complete. tests/ChangeLog: * barrier3.c: Fixed. * barrier4.c: Fixed. * barrier5.c: New; proves that all threads in the group reaching the barrier wait and then resume together. Repeats the test using groups of 1 to 16 threads. Each group of threads must negotiate a large number of barriers (10000). * spin4.c: Fixed. * test.h (error_string): Modified the success (0) value.
2001-07-06Spinlocks and barriers fixed and working. Beta level.rpj
* spin.c: Revamped and working; included static initialiser. * barrier.c: Likewise. * condvar.c: Macro constant change; inline auto init routine. * mutex.c: Likewise. * rwlock.c: Likewise. * private.c: Add support for spinlock initialiser. * global.c: Likewise. * implement.h: Likewise. * pthread.h (PTHREAD_SPINLOCK_INITIALIZER): Fix typo. tests/ChangeLog: * spin3.c: Changed test and fixed. * spin4.c: Fixed. * barrier3.c: Fixed. * barrier4.c: Fixed.
2001-07-05 * barrier.c: Remove static initialisation - irreleventrpj
for this object. * pthread.h (PTHREAD_BARRIER_INITIALIZER): Removed. * rwlock.c (pthread_rwlock_wrlock): This routine is not a cancelation point - disable deferred cancelation around call to pthread_cond_wait(). tests/ChangeLog: * spin1.c: New; testing spinlocks. * spin2.c: New; testing spinlocks. * spin3.c: New; testing spinlocks. * spin4.c: New; testing spinlocks. * barrier1.c: New; testing barriers. * barrier2.c: New; testing barriers. * barrier3.c: New; testing barriers. * barrier4.c: New; testing barriers. * GNUmakefile: Add new tests. * Makefile: Add new tests.
