4482         compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
4483         is not defined.
4484
4485         * spinlock.c (__pthread_unlock): Call
4486         compare_and_swap_with_release_semantics () instead of
4487         compare_and_swap ().
4488
4489 2000-06-19  Ulrich Drepper  <drepper@redhat.com>
4490
4491         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning
4492         to errno directly.

4497
4498 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4499
4500         Timer nodes are now reference counted, and can be marked
4501         as deleted. This allows for the safe release of the global mutex
4502         in the middle without losing the timer being operated on.
4503
4504         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4505         member is now an enum with three values, so that an intermediate
4506         state can be represented (deleted but not free for reuse yet).
4507         New refcount member added.
4508         * sysdeps/pthread/timer_routines.c: Likewise.
4509
4510         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4511         timer_valid): New inline functions added.
4512
4513         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4514         restructured, recursive deadlock bug fixed.
4515
4516         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4517         timer_addref to ensure that timer won't be deleted while mutex is not
4518         held. Also uses timer_invalid to perform validation of timer handle.
4519         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4520         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4521
4522 2000-06-14  Ulrich Drepper  <drepper@redhat.com>

4525         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4526
4527 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4528
4529         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4530         tightened up some critical regions and micro-optimized some list
4531         manipulation code.
4532
4533         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4534         Returns int value now to indicate whether timer was queued at head.
4535         * sysdeps/pthread/posix-timer.h: Likewise.
4536         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4537         new return value from __timer_thread_queue_timer to avoid waking
4538         up timer thread unnecessarily.
4539
4540         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4541         inuse flag, because this requires mutex to be held.  Callers updated
4542         to do the check when they have the mutex.
4543         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4544
4545         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4546         regions: avoids making system calls while holding timer mutex, and
4547         a few computations were moved outside of the mutex as well.
4548         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4549
4550         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4551         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4552         changed to get better better code out of gcc.
4553         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4554         version of list_unlink added here.
4555         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4556         function in all places: idempotent one for timers, non-idempotent
4557         one for thread nodes.
4558         * sysdeps/pthread/timer_settime: Likewise.
4559         * sysdeps/pthread/timer_routines.c: Likewise.
4560
4561 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4562
4563         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4577
4578         * Examples/ex6.c: Test return value of pthread_join.
4579
4580 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4581
4582         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.

4587
4588 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4589
4590         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4591         really append the entry.

4596
4597 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4598
4599         * sysdeps/pthread/timer_create.c: Thread matching now done on
4600         clock type as well as thread attributes.
4601         There are individual global signal-delivering threads for
4602         different clock types.
4603         * sysdeps/pthread/posix-timer.h: Likewise.
4604         * sysdeps/pthread/timer_routines.c: Likewise.
4605
4606         * sysdeps/pthread/timer_routines.c: Thread allocation and
4607         deallocation function now remembers to put thread on active
4608         list and remove from active list.
4609         Thus now the feature of binding multiple timers
4610         to a single thread actually works.
4611
4612 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4613
4614         * pthread.c (__pthread_create_2_1): Optimize a bit.

4618         * join.c (pthread_join): Use nonexisting_handle instead of
4619         invalid_handle to test for acceptable thread handle.
4620         * manager.c (pthread_handle_free): Likewise.
4621         * joinrace.c: New file.
4622         Reported by Permaine Cheung <pcheung@cygnus.com>.

4668
4669         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4673
4674         Added missing fork time handling of global libio lock.
4675
4676         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4677         not just the individual stream locks. Rewritten to use new
4678         iterator interface provided by libio rather than accessing
4679         global variable.
4680
4681         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4682         which lock and unlock the stream list using the new interface
4683         provied by libio.
4684         * internals.h: Likewise.
4685
4686         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4687         and __funlockfilelist in the parent after the fork.
4688         Child still calls __fresetlockfiles as before.
4689
4690         * linuxthreads.texi: Now explains what happens to streams at
4691         fork time. Also whole new section on forking and thread added.
4692         Definition of pthread_atfork moved out of Miscellaneous Functions
4693         to this new section.

4716         * Examples/ex8.c: New file.
4717
4718 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4719
4720         Bugfix: The pthread_atfork mechanism now takes care of its
4721         own internal mutex at fork time.
4722
4723         * ptfork.c (__fork): Revised so that the mutex is held across
4724         the fork operation and while the handlers are called, and so that
4725         the child resets the mutex.
4726
4727         * linuxthreads.texi: Updated pthread_atfork documentation to make
4728         it clear that fork and pthread_atfork can't be reentered from
4729         atfork handlers, that pthread_atfork and fork are mutually atomic,
4730         and that the handlers are inherited by the child process.
4731
4732 2000-05-24  Ulrich Drepper  <drepper@redhat.com>
4733
4734         * Makefile (libpthread-routines): Add pspinlock.
4735         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

4759 2000-05-24  Andreas Jaeger  <aj@suse.de>
4760
4761         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.

4770
4771 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4772
4773         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4774         object state is represented with additional bits which distinguish
4775         whether that state was set up in the current process, or
4776         in an ancestor process. If that state was set in an ancestor,
4777         it means that a fork happened while thread was executing the init
4778         function. In that case, the state is reset to NEVER.
4779         * mutex.c (__pthread_once_fork_prepare): New function.
4780         (__pthread_once_fork_child): Likewise
4781         (__pthread_once_fork_parent): Likewise
4782         (__pthread_reset_pthread_once): Removed.
4783         * ptfork.c (__fork): Call new handlers in mutex.c.
4784         * internals.h: Declarations of new mutex.c functions added.

4788
4789 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4790
4791         * internals.h: New thread manager request type, REQ_KICK.
4792         * join.c (pthread_exit): main thread now calls exit() instead
4793         of _exit() in order to proper process cleanup.
4794         * manager.c (__pthread_manager): Do not terminate manager
4795         after unblocking main thread; wait for main thread's
4796         REQ_PROCESS_EXIT request instead.
4797         Also, added REQ_KICK case to handle new request; this just does
4798         nothing.
4799         * manager.c (pthread_exited): Do not terminate manager after
4800         unblocking main thread.
4801         * manager.c (__pthread_manager_sighandler): If the main thread
4802         is waiting for all other threads to die, send a REQ_KICK into
4803         the thread manager request pipe to get it to clean out the threads
4804         and unblock the main thread as soon as possible. This fixes
4805         the 2000 millisecond hang on shutdown bug.
4806         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4807         including the main one call pthread_exit(), or implicitly do so.
4808         * Makefile (tests): Add ex7.
4809
4810 2000-05-05  Andreas Jaeger  <aj@suse.de>
4811
4812         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c

5237         simultaneously.
5238         * restart.h: Restarts queue even on kernels that don't have
5239         queued real time signals (2.0, early 2.1), thanks to atomic counter,
