Update.

2000-04-13T05:57:21Z

* sysdeps/pthread/pthread.h: Add prototypes for pthread_spin_init, pthread_spin_destroy, pthread_spin_lock, pthread_spin_trylock, and pthread_spin_unlock. * sysdeps/pthread/bits/pthreadtypes.h: Change struct _pthread_fastlock into pthread_spinlock_t. Change all uses. * spinlock.c: Implement pthread_spin_lock. Rename __pthread_unlock to __pthread_spin_unlock and define weak alias for real name. Define pthread_spin_trylock, pthread_spin_init, and pthread_spin_destroy. Change all uses of _pthread_fastlock to pthread_spinlock_t. * spinlock.h: Rename __pthread_unlock to __pthread_spin_unlock. Change all uses of _pthread_fastlock to pthread_spinlock_t. * Versions [libpthread] (GLIBC_2.2): Add pthread_spin_init, pthread_spin_destroy, pthread_spin_lock, pthread_spin_trylock, and pthread_spin_unlock. * cancel.c: Use __pthread_spin_unlock instead of __pthread_unlock. Change all uses of _pthread_fastlock to pthread_spinlock_t. * condvar.c: Likewise. * internals.h: Likewise. * join.c: Likewise. * manager.c: Likewise. * mutex.c: Likewise. * pthread.c: Likewise. * rwlock.c: Likewise. * semaphore.c: Likewise. * signals.c: Likewise.

Update.

2000-03-26 Ulrich Drepper * include/features.h: Undef and document __USE_XOPEN2K. * malloc/mcheck.c: Implement pedantic checking of all allocated blocks whenever a function is called. Initiated by calling mcheck_pedantic instead of mcheck. * malloc/mcheck.h: Declare mcheck_pedantic. * malloc/Versions [libc] (GLIBC_2.2): Add mcheck_pedantic. * locale/programs/localdef.c: Use mcheck_pedantic instead of mcheck for now.

Update.

2000-03-22T08:01:35Z

* sysdeps/unix/sysv/linux/errlist.c: Likewise.

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!).

2000-01-03 Kaz Kylheku 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.
