| | | | | | | | | | | | | | | | | | | | | | points (sem_wait, pthread_join, pthread_cond_{wait,timedwait}). Cancellation won't eat a signal in any of these functions (*required* by POSIX and Single Unix Spec!). 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net> Redesigned how cancellation unblocks a thread from internal cancellation points (sem_wait, pthread_join, pthread_cond_{wait,timedwait}). Cancellation won't eat a signal in any of these functions (*required* by POSIX and Single Unix Spec!). * condvar.c: spontaneous wakeup on pthread_cond_timedwait won't eat a simultaneous condition variable signal (not required by POSIX or Single Unix Spec, but nice). * spinlock.c: __pthread_lock queues back any received restarts that don't belong to it instead of assuming ownership of lock upon any restart; fastlock can no longer be acquired by two threads simultaneously. * restart.h: restarts queue even on kernels that don't have queued real time signals (2.0, early 2.1), thanks to atomic counter, avoiding a rare race condition in pthread_cond_timedwait.
