4489         * Makefile (libpthread-routines): Add barrier.
4490         (tests): Add ex9.  Add rule to build ex9.
4491         * Versions: Export barrier functions.
4492         * barrier.c: New file.
4493         * Examples/ex9.c: New file.
4494         * sysdeps/pthread/pthread.h: Add barrier data types and declarations.
4495         * sysdeps/pthread/bits/pthreadtypes.h: Likewise.
4496         Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
4497
4498 2000-06-19  H.J. Lu  <hjl@gnu.org>
4499
4500         * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
4501         HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
4502         (compare_and_swap_with_release_semantics): New. Default to
4503         compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
4504         is not defined.
4505
4506         * spinlock.c (__pthread_unlock): Call
4507         compare_and_swap_with_release_semantics () instead of
4508         compare_and_swap ().
4509
4510 2000-06-19  Ulrich Drepper  <drepper@redhat.com>
4511
4512         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning
4513         to errno directly.

4518
4519 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4520
4521         Timer nodes are now reference counted, and can be marked
4522         as deleted. This allows for the safe release of the global mutex
4523         in the middle without losing the timer being operated on.
4524
4525         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4526         member is now an enum with three values, so that an intermediate
4527         state can be represented (deleted but not free for reuse yet).
4528         New refcount member added.
4529         * sysdeps/pthread/timer_routines.c: Likewise.
4530
4531         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4532         timer_valid): New inline functions added.
4533
4534         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4535         restructured, recursive deadlock bug fixed.
4536
4537         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4538         timer_addref to ensure that timer won't be deleted while mutex is not
4539         held. Also uses timer_invalid to perform validation of timer handle.
4540         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4541         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4542
4543 2000-06-14  Ulrich Drepper  <drepper@redhat.com>

4546         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4547
4548 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4549
4550         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4551         tightened up some critical regions and micro-optimized some list
4552         manipulation code.
4553
4554         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4555         Returns int value now to indicate whether timer was queued at head.
4556         * sysdeps/pthread/posix-timer.h: Likewise.
4557         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4558         new return value from __timer_thread_queue_timer to avoid waking
4559         up timer thread unnecessarily.
4560
4561         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4562         inuse flag, because this requires mutex to be held.  Callers updated
4563         to do the check when they have the mutex.
4564         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4565
4566         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4567         regions: avoids making system calls while holding timer mutex, and
4568         a few computations were moved outside of the mutex as well.
4569         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4570
4571         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4572         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4573         changed to get better better code out of gcc.
4574         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4575         version of list_unlink added here.
4576         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4577         function in all places: idempotent one for timers, non-idempotent
4578         one for thread nodes.
4579         * sysdeps/pthread/timer_settime: Likewise.
4580         * sysdeps/pthread/timer_routines.c: Likewise.
4581
4582 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4583
4584         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4597         * Makefile (tests): Add joinrace.
4598
4599         * Examples/ex6.c: Test return value of pthread_join.
4600
4601 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4602
4603         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4604         (__pthread_spin_trylock): Implement.
4605         (__pthread_spin_unlock): Implement.
4606         (__pthread_spin_init): Implement.
4607         (__pthread_spin_destroy): Implement.
4608
4609 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4610
4611         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4612         really append the entry.

4617
4618 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4619
4620         * sysdeps/pthread/timer_create.c: Thread matching now done on
4621         clock type as well as thread attributes.
4622         There are individual global signal-delivering threads for
4623         different clock types.
4624         * sysdeps/pthread/posix-timer.h: Likewise.
4625         * sysdeps/pthread/timer_routines.c: Likewise.
4626
4627         * sysdeps/pthread/timer_routines.c: Thread allocation and
4628         deallocation function now remembers to put thread on active
4629         list and remove from active list.
4630         Thus now the feature of binding multiple timers
4631         to a single thread actually works.
4632
4633 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4634
4635         * pthread.c (__pthread_create_2_1): Optimize a bit.
4636
4637         * internals.h (invalid_handle): Also test for p_terminated != 0.
4638         (nonexisting_handle): New function.  Same as old invalid_handle.
4639         * join.c (pthread_join): Use nonexisting_handle instead of
4640         invalid_handle to test for acceptable thread handle.
4641         * manager.c (pthread_handle_free): Likewise.
4642         * joinrace.c: New file.
4643         Reported by Permaine Cheung <pcheung@cygnus.com>.

4689
4690         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4694
4695         Added missing fork time handling of global libio lock.
4696
4697         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4698         not just the individual stream locks. Rewritten to use new
4699         iterator interface provided by libio rather than accessing
4700         global variable.
4701
4702         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4703         which lock and unlock the stream list using the new interface
4704         provied by libio.
4705         * internals.h: Likewise.
4706
4707         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4708         and __funlockfilelist in the parent after the fork.
4709         Child still calls __fresetlockfiles as before.
4710
4711         * linuxthreads.texi: Now explains what happens to streams at
4712         fork time. Also whole new section on forking and thread added.
4713         Definition of pthread_atfork moved out of Miscellaneous Functions
4714         to this new section.
4715
4716 2000-06-04  Jakub Jelinek  <jakub@redhat.com>

4736         * Makefile (tests): Add ex8.
4737         * Examples/ex8.c: New file.
4738
4739 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4740
4741         Bugfix: The pthread_atfork mechanism now takes care of its
4742         own internal mutex at fork time.
4743
4744         * ptfork.c (__fork): Revised so that the mutex is held across
4745         the fork operation and while the handlers are called, and so that
4746         the child resets the mutex.
4747
4748         * linuxthreads.texi: Updated pthread_atfork documentation to make
4749         it clear that fork and pthread_atfork can't be reentered from
4750         atfork handlers, that pthread_atfork and fork are mutually atomic,
4751         and that the handlers are inherited by the child process.
4752
4753 2000-05-24  Ulrich Drepper  <drepper@redhat.com>
4754
4755         * Makefile (libpthread-routines): Add pspinlock.
4756         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.
4757         Use struct _pthread_fastlock instead of pthread_spinlock_t.

4778         back to _pthread_fastlock.  Define new pthread_spinlock_t.
4779
4780 2000-05-24  Andreas Jaeger  <aj@suse.de>
4781
4782         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.

4791
4792 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4793
4794         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4795         object state is represented with additional bits which distinguish
4796         whether that state was set up in the current process, or
4797         in an ancestor process. If that state was set in an ancestor,
4798         it means that a fork happened while thread was executing the init
4799         function. In that case, the state is reset to NEVER.
4800         * mutex.c (__pthread_once_fork_prepare): New function.
4801         (__pthread_once_fork_child): Likewise
4802         (__pthread_once_fork_parent): Likewise
4803         (__pthread_reset_pthread_once): Removed.
4804         * ptfork.c (__fork): Call new handlers in mutex.c.
4805         * internals.h: Declarations of new mutex.c functions added.
4806         Declaration of removed function deleted.
4807         * linuxthreads.texi: Updated documentation about pthread_once
4808         to clarify what happens under cancellation and forking.
4809
4810 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4811
4812         * internals.h: New thread manager request type, REQ_KICK.
4813         * join.c (pthread_exit): main thread now calls exit() instead
4814         of _exit() in order to proper process cleanup.
4815         * manager.c (__pthread_manager): Do not terminate manager
4816         after unblocking main thread; wait for main thread's
4817         REQ_PROCESS_EXIT request instead.
4818         Also, added REQ_KICK case to handle new request; this just does
4819         nothing.
4820         * manager.c (pthread_exited): Do not terminate manager after
4821         unblocking main thread.
4822         * manager.c (__pthread_manager_sighandler): If the main thread
4823         is waiting for all other threads to die, send a REQ_KICK into
4824         the thread manager request pipe to get it to clean out the threads
4825         and unblock the main thread as soon as possible. This fixes
4826         the 2000 millisecond hang on shutdown bug.
4827         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4828         including the main one call pthread_exit(), or implicitly do so.
4829         * Makefile (tests): Add ex7.
4830
4831 2000-05-05  Andreas Jaeger  <aj@suse.de>

5258         simultaneously.
5259         * restart.h: Restarts queue even on kernels that don't have
5260         queued real time signals (2.0, early 2.1), thanks to atomic counter,
