EunBong Song	03bd3688bc	pthread: Fix compilation error on pthread_cond_wait when CONFIG_CANCELLATION_POINTS and CONFIG_PTHREAD_MUTEX_UNSAFE are enabled.	2017-05-02 07:14:04 -06:00
Juha Niskanen (Haltian)	b4747286b1	Add logic to disable cancellation points within the OS. This is useful when an internal OS function that is NOT a cancellation point calls an OS function which is a cancellation point. In that case, irrecoverable states may occur if the cancellation is within the OS.	2017-04-11 11:03:25 -06:00
Gregory Nutt	eb344d7260	Fix an assertion noted by Jussi Kivilinna. ... This was a consequence of the recent robust mutex changes. If robust mutexes are selected, then each mutex that a thread takes is retained in a list in threads TCB. If the thread exits and that list is not empty, then we know that the thread exitted while holding mutexes. And, in that case, each will be marked as inconsistent and the any waiter for the thread is awakened. For the case of pthread_mutex_trywait(), the mutex was not being added to the list! while not usually a fatal error, this was caught by an assertion when pthread_mutex_unlock() was called: It tried to remove the mutex from the TCB list and it was not there when, of course, it shoule be. The fix was to add pthread_mutex_trytake() which does sem_trywait() and if successful, does correctly add the mutext to the TCB list. This should eliminated the assertion.	2017-03-29 07:50:40 -06:00

Gregory Nutt	34c5e1c18f	Minor cleanup from recent changes.	2017-03-26 14:04:07 -06:00
Gregory Nutt	fe03ef02c4	when pthread exits or is cancelled, mutexes held by thread are marked inconsistent and the highest priority thread waiting for the mutex is awakened.	2017-03-26 13:37:05 -06:00
Gregory Nutt	6e623ce06f	pthreads: Partial implementation of final part of robust mutexes: Keep list of all mutexes held by a thread in a list in the TCB.	2017-03-26 12:46:57 -06:00
Gregory Nutt	2c37d369ab	pthread: Fix return value of pthread_give/takesemaphore(). Add option to pthread_takesemaphore to ignore EINTR or not.	2017-03-26 11:22:17 -06:00
