4568
4569         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning

4577
4578         Timer nodes are now reference counted, and can be marked
4579         as deleted. This allows for the safe release of the global mutex
4580         in the middle without losing the timer being operated on.
4581
4582         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4583         member is now an enum with three values, so that an intermediate
4584         state can be represented (deleted but not free for reuse yet).
4585         New refcount member added.
4586         * sysdeps/pthread/timer_routines.c: Likewise.

4592         restructured, recursive deadlock bug fixed.
4593
4594         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4595         timer_addref to ensure that timer won't be deleted while mutex is not
4596         held. Also uses timer_invalid to perform validation of timer handle.
4597         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4598         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4599

4606
4607         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4608         tightened up some critical regions and micro-optimized some list
4609         manipulation code.
4610
4611         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4612         Returns int value now to indicate whether timer was queued at head.
4613         * sysdeps/pthread/posix-timer.h: Likewise.
4614         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4615         new return value from __timer_thread_queue_timer to avoid waking
4616         up timer thread unnecessarily.
4617
4618         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4619         inuse flag, because this requires mutex to be held.  Callers updated
4620         to do the check when they have the mutex.
4621         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4622
4623         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4624         regions: avoids making system calls while holding timer mutex, and
4625         a few computations were moved outside of the mutex as well.
4626         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4627
4628         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4629         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4630         changed to get better better code out of gcc.
4631         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4632         version of list_unlink added here.
4633         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4634         function in all places: idempotent one for timers, non-idempotent
4635         one for thread nodes.
4636         * sysdeps/pthread/timer_settime: Likewise.
4637         * sysdeps/pthread/timer_routines.c: Likewise.
4638
4639 2000-06-13  Ulrich Drepper  <drepper@redhat.com>

4676
4677         * sysdeps/pthread/timer_create.c: Thread matching now done on
4678         clock type as well as thread attributes.
4679         There are individual global signal-delivering threads for
4680         different clock types.
4681         * sysdeps/pthread/posix-timer.h: Likewise.
4682         * sysdeps/pthread/timer_routines.c: Likewise.
4683
4684         * sysdeps/pthread/timer_routines.c: Thread allocation and
4685         deallocation function now remembers to put thread on active
4686         list and remove from active list.
4687         Thus now the feature of binding multiple timers
4688         to a single thread actually works.

4799         own internal mutex at fork time.

4854         in an ancestor process. If that state was set in an ancestor,
4855         it means that a fork happened while thread was executing the init
4856         function. In that case, the state is reset to NEVER.

4875         Also, added REQ_KICK case to handle new request; this just does
4876         nothing.
4877         * manager.c (pthread_exited): Do not terminate manager after

4882         and unblock the main thread as soon as possible. This fixes
4883         the 2000 millisecond hang on shutdown bug.
4884         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4885         including the main one call pthread_exit(), or implicitly do so.
4886         * Makefile (tests): Add ex7.

5303
5304         Redesigned how cancellation unblocks a thread from internal
5305         cancellation points (sem_wait, pthread_join,
5306         pthread_cond_{wait,timedwait}).
5307         Cancellation won't eat a signal in any of these functions
5308         (*required* by POSIX and Single Unix Spec!).
5309         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5310         simultaneous condition variable signal (not required by POSIX
5311         or Single Unix Spec, but nice).
5312         * spinlock.c: __pthread_lock queues back any received restarts
5313         that don't belong to it instead of assuming ownership of lock
5314         upon any restart; fastlock can no longer be acquired by two threads
5315         simultaneously.
5316         * restart.h: Restarts queue even on kernels that don't have
5317         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5318         avoiding a rare race condition in pthread_cond_timedwait.
