2014-11-02Fix safety of pthread_barrier_waitSamuel Thibault
The barrier queue uses threads' next field, so it can not actually be safely walked without holding the barrier lock. * sysdeps/generic/pt-barrier-wait.c (pthread_barrier_wait): Record an array of __pthread to wake while holding the lock, and wake them only after unlocking it.

so that they may have a chance to actually preempt us. Otherwise they will merely immediately fail to acquire the spin lock, and thus preemption will have served no purpose. * sysdeps/generic/pt-rwlock-unlock.c (pthread_rwlock_unlock): Record an array of __pthread to wake while holding the lock, and wake them only after unlocking it.

2014-05-02Fix guardsize semanticSamuel Thibault
POSIX says guardsize is in addition to stacksize, not included. * pthread/pt-create.c (__pthread_create_internal): Use setup->guardsize + setup->stacksize as stack allocation size.

2014-04-04Use only clock_gettime, do not depend on librtSamuel Thibault
clock_gettime is actually provided by libc, not librt, so we don't need the latter, and thus avoid the librt dependency, which would cause initialization issues. * sysdeps/generic/pt-condattr-setclock.c (pthread_condattr_setclock): Use clock_gettime instead of clock_getres to test for clock availability. * Makefile: Do not link against librt.

2013-12-29Revert "Allow applications to set the default stack size"Richard Braun
This reverts commit 536420a581f9f822cdef0fc460b5176a840f49e5. Now that threadvars have been replaced with TLS, this hack is no longer needed.

2013-02-04Fix pthread timeout handling and cancellation issuesRichard Braun
This patch solves two issues. The first one is cancellation handling when a cancellation request is sent before reaching a cancellation point (namely, pthread_cond_{timed,}wait). Cancellation is implemented by pushing an appropriate cleanup handler and switching to PTHREAD_CANCEL_ASYNCHRONOUS type. The main problem is that it doesn't handle pending requests, only a cancellation that occurs while blocking. Other problems occur when trying to correctly handle a timeout and a cancellation request through the cleanup routine. The other issue is correctly handling timeouts. This problem was already well known, as explained by the following comment : "FIXME: What do we do if we get a wakeup message before we disconnect ourself? It may remain until the next time we block." In addition, the prevp thread member is inconsistently used. It is sometimes accessed while protected by the appropriate queue lock to determine whether a thread is still queued, while at times, threads are unqueued without holding a lock, as in pthread_cond_broadcast : /* We can safely walk the list of waiting threads without holding the lock since it is now decoupled from the condition. */ __pthread_dequeuing_iterate (wakeup, wakeup) __pthread_wakeup (wakeup); This is the root cause that triggers some assertion failures. The solution brought by this patch is to consistently use the prevp link to determine if both a thread has been unqueued and if a wakeup message has been sent (both are needed to wake up a thread). A thread unblocked because of a timeout can now accurately determine if it needs to drain its message queue. A direct improvement is that the message queue size can be limited to one message, and wakeups are guaranteed to be non-blocking, which allows safely calling __pthread_wakeup from critical sections. As it now affects the cleanup cancellation routine of __pthread_cond_timedwait_internal, cancellation is reworked as well. Cancellation type is forced to PTHREAD_CANCEL_DEFERRED during the call, and actually checked on both entry and return. A hook is set by the blocking thread so that the waker doesn't need to know about the call implementation. Cancellation members are now protected with a mutex for truely safe access. * pthread/pt-alloc.c (initialize_pthread): Initialize the new `cancel_lock', `cancel_hook' and `cancel_hook_args' fields. * pthread/pt-cancel.c (pthread_cancel): Rework cancellation handling. * pthread/pt-internal.h (struct __pthread): Add `cancel_lock', `cancel_hook' and `cancel_hook_args' fields.
