4297
4298         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning

4306
4307         Timer nodes are now reference counted, and can be marked
4308         as deleted. This allows for the safe release of the global mutex
4309         in the middle without losing the timer being operated on.
4310
4311         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4312         member is now an enum with three values, so that an intermediate
4313         state can be represented (deleted but not free for reuse yet).
4314         New refcount member added.
4315         * sysdeps/pthread/timer_routines.c: Likewise.

4319
4320         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4321         restructured, recursive deadlock bug fixed.
4322
4323         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4324         timer_addref to ensure that timer won't be deleted while mutex is not
4325         held. Also uses timer_invalid to perform validation of timer handle.
4326         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4327         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4328

4335
4336         A few optimizations.  Got rid of unnecessary wakeups of timer threads,

4338         manipulation code.
4339
4340         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):

4342         * sysdeps/pthread/posix-timer.h: Likewise.
4343         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4344         new return value from __timer_thread_queue_timer to avoid waking
4345         up timer thread unnecessarily.
4346
4347         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4348         inuse flag, because this requires mutex to be held.  Callers updated
4349         to do the check when they have the mutex.
4350         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4351
4352         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4353         regions: avoids making system calls while holding timer mutex, and
4354         a few computations were moved outside of the mutex as well.
4355         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4356
4357         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4358         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4359         changed to get better better code out of gcc.
4360         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4361         version of list_unlink added here.
4362         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4363         function in all places: idempotent one for timers, non-idempotent
4364         one for thread nodes.
4365         * sysdeps/pthread/timer_settime: Likewise.
4366         * sysdeps/pthread/timer_routines.c: Likewise.
4367
4368 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4369
4370         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4385         * Examples/ex6.c: Test return value of pthread_join.
4386
4387 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4388
4389         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4390         (__pthread_spin_trylock): Implement.
4391         (__pthread_spin_unlock): Implement.
4392         (__pthread_spin_init): Implement.

4394
4395 2000-06-10  Ulrich Drepper  <drepper@redhat.com>

4404 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4405
4406         * sysdeps/pthread/timer_create.c: Thread matching now done on
4407         clock type as well as thread attributes.
4408         There are individual global signal-delivering threads for
4409         different clock types.
4410         * sysdeps/pthread/posix-timer.h: Likewise.
4411         * sysdeps/pthread/timer_routines.c: Likewise.
4412
4413         * sysdeps/pthread/timer_routines.c: Thread allocation and
4414         deallocation function now remembers to put thread on active
4415         list and remove from active list.
4416         Thus now the feature of binding multiple timers
4417         to a single thread actually works.
4418

4420
4421         * pthread.c (__pthread_create_2_1): Optimize a bit.

4428         * joinrace.c: New file.
4429         Reported by Permaine Cheung <pcheung@cygnus.com>.

4482
4483         * lockfile.c (__fresetlockfiles): Now also resets the list lock,

4527         Bugfix: The pthread_atfork mechanism now takes care of its
4528         own internal mutex at fork time.
4529
4530         * ptfork.c (__fork): Revised so that the mutex is held across
4531         the fork operation and while the handlers are called, and so that
4532         the child resets the mutex.
4533
4534         * linuxthreads.texi: Updated pthread_atfork documentation to make
4535         it clear that fork and pthread_atfork can't be reentered from

4537         and that the handlers are inherited by the child process.

4581         object state is represented with additional bits which distinguish
4582         whether that state was set up in the current process, or
4583         in an ancestor process. If that state was set in an ancestor,
4584         it means that a fork happened while thread was executing the init
4585         function. In that case, the state is reset to NEVER.
4586         * mutex.c (__pthread_once_fork_prepare): New function.

4602         after unblocking main thread; wait for main thread's
4603         REQ_PROCESS_EXIT request instead.
4604         Also, added REQ_KICK case to handle new request; this just does
4605         nothing.
4606         * manager.c (pthread_exited): Do not terminate manager after
4607         unblocking main thread.
4608         * manager.c (__pthread_manager_sighandler): If the main thread
4609         is waiting for all other threads to die, send a REQ_KICK into
4610         the thread manager request pipe to get it to clean out the threads
4611         and unblock the main thread as soon as possible. This fixes
4612         the 2000 millisecond hang on shutdown bug.
4613         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4614         including the main one call pthread_exit(), or implicitly do so.
4615         * Makefile (tests): Add ex7.
4616
4617 2000-05-05  Andreas Jaeger  <aj@suse.de>

5041         * spinlock.c: __pthread_lock queues back any received restarts
5042         that don't belong to it instead of assuming ownership of lock
5043         upon any restart; fastlock can no longer be acquired by two threads
5044         simultaneously.
5045         * restart.h: Restarts queue even on kernels that don't have
5046         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5047         avoiding a rare race condition in pthread_cond_timedwait.

6300         * pthread.c (__pthread_initial_thread): Correct
6301         initializer.

6307         Since sigset_t no longer fits in a register, we can't pass in the
6308         thread's initial mask so easily.  Take this opportunity to simplify
6309         the clone implementation by only accepting a single void* argument.
6310
6311         * manager.c (__pthread_manager): Put thread vitals in the thread
6312         struct instead of as arguments through clone.
6313         (pthread_start_thread): Look for them there.
6314         * internals.h (struct _pthread): Add p_initial_fn,
6315         p_initial_fn_arg, p_initial_mask.  Fix __pthread_manager proto.
6316         * pthread.c (pthread_initialize_manager): Revise clone invocation.
