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.
2014-11-02Wake up queued threads without spin lock heldSamuel Thibault

2014-11-02Wake up queued threads without spin lock heldSamuel Thibault
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-cond-brdcast.c (__pthread_cond_broadcast): Unlock cond->__lock while waking the queued thread.

2014-08-31Fix stack address computationSamuel Thibault
stackaddr is supposed to be an adressable byte, i.e. not inside the guard size. * pthread/pt-getattr.c (pthread_getattr_np): Take guard size into account when returning the stack bottom address.
2014-08-20Add __pthread_key_create aliasSamuel Thibault
Some versions of std::thread use it to detect the presence of libpthread (don't ask why) * sysdeps/hurd/pt-key-create.c (pthread_key_create): Rename to __pthread_key_create. (pthread_key_create): Define as strong alias of __pthread_key_create. * Versions (libpthread): Add __pthread_key_create.

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. Do not truncate guardsize to stacksize. * pthread/pt-internal.h (guardsize): Remove comment. * sysdeps/generic/pt-attr-setstacksize.c (pthread_attr_setstacksize): Do not truncate guardsize to stacksize.
2014-04-07Merge branch 'foo'Samuel Thibault
2014-04-07We don't have Hurd TSD any more, drop TODO entrySamuel Thibault
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.

(struct __pthread): New `res_state' member.
2014-01-22Fix up the main thread TCBRichard Braun
Unlike other threads, the TCB of the main thread is created by the C library before libpthread is initialized and needs special care. * sysdeps/mach/hurd/i386/pt-setup.c (__pthread_setup): Set the `self' member of the main thread TCB.
2014-01-22Fix thread destructionRichard Braun
Releasing a thread reference uses a mutex, which means the kernel resources used for synchronization must be available until late during the destruction process. For simplicity, merge __pthread_thread_dealloc into __pthread_thread_terminate. * Makefile (libpthread-routines): Remove pt-thread-dealloc. * pthread/pt-create.c (__pthread_create_internal): Remove call to __pthread_thread_dealloc. * pthread/pt-exit.c (__pthread_exit): Likewise. * pthread/pt-internal.h (__pthread_thread_dealloc): Remove declaration.

2014-01-02Revert "Fix glibc spinlock inclusion"Samuel Thibault
This reverts commit 414e0bbabb6ac7a5cff148b927ec874dff922be1. It's these versions which would end up being installed. Some other way needs to be found, or else we'll have to just duplicate or move the content.
2014-01-02Fix glibc spinlock inclusionSamuel Thibault
Using an i386 Implies would change inclusion order in the rest of libc too, entailing a lot of issues. We can simply make mach/i386 include i386 instead. * sysdeps/mach/i386/bits/spin-lock-inline.h: Include ../../../sysdeps/i386/bits/spin-lock-inline.h. * sysdeps/mach/i386/bits/spin-lock.h: Include ../../../sysdeps/i386/bits/spin-lock.h.

2014-01-01Add compatibility with kernels without __thread_terminate_releaseSamuel Thibault
This would leak, but at least let the user reboot nicely into a newer kernel. * sysdeps/mach/pt-thread-terminate.c (__pthread_thread_terminate): If __thread_terminate_release returns, use __thread_terminate to terminate the thread anyway.
