2013-02-15Add pthread_hurd_cond_timedwait_npRichard Braun
This new Hurd-specific function is meant to allow Hurd servers to wait for events during a bounded period of time. * Makefile (libpthread-routines): Add pt-hurd-cond-timedwait. * Versions: Include pthread_hurd_cond_timedwait_np in version GLIBC_2.17 of libpthread. * sysdeps/mach/hurd/bits/pthread-np.h (pthread_hurd_cond_timedwait_np): New declaration. * sysdeps/mach/hurd/pt-hurd-cond-timedwait.c: New file that provides __pthread_hurd_cond_timedwait_internal and __pthread_hurd_cond_timedwait_np. * sysdeps/mach/hurd/pt-hurd-cond-wait.c (__pthread_hurd_cond_wait_np): Rewrite as a call to __pthread_hurd_cond_timedwait_internal with no timeout.
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.

2012-11-25Fix pthread_hurd_cond_wait_np versionsSamuel Thibault
* Version: Do not include pthread_hurd_cond_wait_np in libc, as we don't define a forward for it. Include pthread_hurd_cond_wait_np in version GLIBC_2.17 of libpthread, as this is a new symbol.
2012-11-25Allow applications to set the default stack sizeRichard Braun

2012-11-24Set elf=yes if not defined alreadyPino Toscano
glibc 2.16 dropped support for any binary format other than ELF, and the ELF variable has been removed too; this causes a build failure when built as glibc addon with glibc >= 2.16, since it would not link to ld.so. Defining ELF to 'yes' if not defined allows to retain compatibility with older glibc versions. * Makefile [$(..) != ''] [$(elf) = ''] (elf): Define to 'yes'.

When deleting a key using `pthread_key_delete', delete all the values associated to that key in all the threads available.
