4122         * sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add
4123         load of spin lock to prime the cache before the atomic compare and

4484         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning
4485         to errno directly.
4486         * sysdeps/pthread/timer_delete.c: Likewise.
4487         * sysdeps/pthread/timer_getoverr.c: Likewise.

4491 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4492
4493         Timer nodes are now reference counted, and can be marked
4494         as deleted. This allows for the safe release of the global mutex
4495         in the middle without losing the timer being operated on.
4496
4497         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4498         member is now an enum with three values, so that an intermediate
4499         state can be represented (deleted but not free for reuse yet).
4500         New refcount member added.
4501         * sysdeps/pthread/timer_routines.c: Likewise.
4502
4503         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4504         timer_valid): New inline functions added.
4505
4506         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4507         restructured, recursive deadlock bug fixed.
4508
4509         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4510         timer_addref to ensure that timer won't be deleted while mutex is not
4511         held. Also uses timer_invalid to perform validation of timer handle.
4512         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4513         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4514
4515 2000-06-14  Ulrich Drepper  <drepper@redhat.com>
4516
4517         * shlib-versions: Add entry for SH.
4518         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4519
4520 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4521
4522         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4523         tightened up some critical regions and micro-optimized some list
4524         manipulation code.
4525
4526         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4527         Returns int value now to indicate whether timer was queued at head.
4528         * sysdeps/pthread/posix-timer.h: Likewise.
4529         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4530         new return value from __timer_thread_queue_timer to avoid waking
4531         up timer thread unnecessarily.
4532
4533         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4534         inuse flag, because this requires mutex to be held.  Callers updated
4535         to do the check when they have the mutex.
4536         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4537
4538         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4539         regions: avoids making system calls while holding timer mutex, and
4540         a few computations were moved outside of the mutex as well.
4541         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4542
4543         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4544         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4545         changed to get better better code out of gcc.
4546         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4547         version of list_unlink added here.
4548         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4549         function in all places: idempotent one for timers, non-idempotent
4550         one for thread nodes.
4551         * sysdeps/pthread/timer_settime: Likewise.
4552         * sysdeps/pthread/timer_routines.c: Likewise.
4553
4554 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4555
4556         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4570
4571         * Examples/ex6.c: Test return value of pthread_join.
4572
4573 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4574
4575         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.

4577         (__pthread_spin_unlock): Implement.
4578         (__pthread_spin_init): Implement.
4579         (__pthread_spin_destroy): Implement.
4580
4581 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4582
4583         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4584         really append the entry.

4589
4590 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4591
4592         * sysdeps/pthread/timer_create.c: Thread matching now done on
4593         clock type as well as thread attributes.
4594         There are individual global signal-delivering threads for
4595         different clock types.
4596         * sysdeps/pthread/posix-timer.h: Likewise.
4597         * sysdeps/pthread/timer_routines.c: Likewise.
4598
4599         * sysdeps/pthread/timer_routines.c: Thread allocation and
4600         deallocation function now remembers to put thread on active
4601         list and remove from active list.
4602         Thus now the feature of binding multiple timers
4603         to a single thread actually works.
4604
4605 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4606
4607         * pthread.c (__pthread_create_2_1): Optimize a bit.

4610         (nonexisting_handle): New function.  Same as old invalid_handle.
4611         * join.c (pthread_join): Use nonexisting_handle instead of
4612         invalid_handle to test for acceptable thread handle.
4613         * manager.c (pthread_handle_free): Likewise.
4614         * joinrace.c: New file.
4615         Reported by Permaine Cheung <pcheung@cygnus.com>.

4661
4662         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4666
4667         Added missing fork time handling of global libio lock.
4668
4669         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4670         not just the individual stream locks. Rewritten to use new
4671         iterator interface provided by libio rather than accessing
4672         global variable.
4673
4674         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4675         which lock and unlock the stream list using the new interface
4676         provied by libio.
4677         * internals.h: Likewise.
4678
4679         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4680         and __funlockfilelist in the parent after the fork.
4681         Child still calls __fresetlockfiles as before.
4682
4683         * linuxthreads.texi: Now explains what happens to streams at
4684         fork time. Also whole new section on forking and thread added.
4685         Definition of pthread_atfork moved out of Miscellaneous Functions
4686         to this new section.

4710
4711 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4712
4713         Bugfix: The pthread_atfork mechanism now takes care of its
4714         own internal mutex at fork time.
4715
4716         * ptfork.c (__fork): Revised so that the mutex is held across
4717         the fork operation and while the handlers are called, and so that
4718         the child resets the mutex.
4719
4720         * linuxthreads.texi: Updated pthread_atfork documentation to make
4721         it clear that fork and pthread_atfork can't be reentered from
4722         atfork handlers, that pthread_atfork and fork are mutually atomic,
4723         and that the handlers are inherited by the child process.
4724
4725 2000-05-24  Ulrich Drepper  <drepper@redhat.com>
4726
4727         * Makefile (libpthread-routines): Add pspinlock.
4728         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

4751
4752 2000-05-24  Andreas Jaeger  <aj@suse.de>
4753
4754         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.

4766         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4767         object state is represented with additional bits which distinguish
4768         whether that state was set up in the current process, or
4769         in an ancestor process. If that state was set in an ancestor,
4770         it means that a fork happened while thread was executing the init
4771         function. In that case, the state is reset to NEVER.
4772         * mutex.c (__pthread_once_fork_prepare): New function.
4773         (__pthread_once_fork_child): Likewise
4774         (__pthread_once_fork_parent): Likewise
4775         (__pthread_reset_pthread_once): Removed.
4776         * ptfork.c (__fork): Call new handlers in mutex.c.

4781
4782 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4783
4784         * internals.h: New thread manager request type, REQ_KICK.
4785         * join.c (pthread_exit): main thread now calls exit() instead
4786         of _exit() in order to proper process cleanup.
4787         * manager.c (__pthread_manager): Do not terminate manager
4788         after unblocking main thread; wait for main thread's
4789         REQ_PROCESS_EXIT request instead.
4790         Also, added REQ_KICK case to handle new request; this just does
4791         nothing.
4792         * manager.c (pthread_exited): Do not terminate manager after
4793         unblocking main thread.
4794         * manager.c (__pthread_manager_sighandler): If the main thread
4795         is waiting for all other threads to die, send a REQ_KICK into
4796         the thread manager request pipe to get it to clean out the threads
4797         and unblock the main thread as soon as possible. This fixes
4798         the 2000 millisecond hang on shutdown bug.
4799         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4800         including the main one call pthread_exit(), or implicitly do so.
4801         * Makefile (tests): Add ex7.
4802
4803 2000-05-05  Andreas Jaeger  <aj@suse.de>
4804
4805         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c

5230         simultaneously.
5231         * restart.h: Restarts queue even on kernels that don't have
5232         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5233         avoiding a rare race condition in pthread_cond_timedwait.
