4497         * Makefile (libpthread-routines): Add barrier.
4498         (tests): Add ex9.  Add rule to build ex9.
4499         * Versions: Export barrier functions.
4500         * barrier.c: New file.
4501         * Examples/ex9.c: New file.

4503         * sysdeps/pthread/bits/pthreadtypes.h: Likewise.
4504         Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
4505
4506 2000-06-19  H.J. Lu  <hjl@gnu.org>
4507
4508         * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
4509         HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
4510         (compare_and_swap_with_release_semantics): New. Default to
4511         compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
4512         is not defined.
4513
4514         * spinlock.c (__pthread_unlock): Call
4515         compare_and_swap_with_release_semantics () instead of
4516         compare_and_swap ().
4517
4518 2000-06-19  Ulrich Drepper  <drepper@redhat.com>
4519
4520         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning
4521         to errno directly.

4526
4527 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4528
4529         Timer nodes are now reference counted, and can be marked
4530         as deleted. This allows for the safe release of the global mutex
4531         in the middle without losing the timer being operated on.
4532
4533         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4534         member is now an enum with three values, so that an intermediate
4535         state can be represented (deleted but not free for reuse yet).
4536         New refcount member added.
4537         * sysdeps/pthread/timer_routines.c: Likewise.
4538
4539         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4540         timer_valid): New inline functions added.
4541
4542         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4543         restructured, recursive deadlock bug fixed.
4544
4545         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4546         timer_addref to ensure that timer won't be deleted while mutex is not
4547         held. Also uses timer_invalid to perform validation of timer handle.
4548         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4549         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4550
4551 2000-06-14  Ulrich Drepper  <drepper@redhat.com>

4554         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4555
4556 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4557
4558         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4559         tightened up some critical regions and micro-optimized some list
4560         manipulation code.
4561
4562         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4563         Returns int value now to indicate whether timer was queued at head.
4564         * sysdeps/pthread/posix-timer.h: Likewise.
4565         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4566         new return value from __timer_thread_queue_timer to avoid waking
4567         up timer thread unnecessarily.
4568
4569         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4570         inuse flag, because this requires mutex to be held.  Callers updated
4571         to do the check when they have the mutex.
4572         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4573
4574         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4575         regions: avoids making system calls while holding timer mutex, and
4576         a few computations were moved outside of the mutex as well.
4577         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4578
4579         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4580         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4581         changed to get better better code out of gcc.
4582         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4583         version of list_unlink added here.
4584         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4585         function in all places: idempotent one for timers, non-idempotent
4586         one for thread nodes.
4587         * sysdeps/pthread/timer_settime: Likewise.
4588         * sysdeps/pthread/timer_routines.c: Likewise.
4589
4590 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4591
4592         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4605         * Makefile (tests): Add joinrace.
4606
4607         * Examples/ex6.c: Test return value of pthread_join.
4608
4609 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4610
4611         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4612         (__pthread_spin_trylock): Implement.
4613         (__pthread_spin_unlock): Implement.
4614         (__pthread_spin_init): Implement.
4615         (__pthread_spin_destroy): Implement.
4616
4617 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4618
4619         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4620         really append the entry.

4625
4626 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4627
4628         * sysdeps/pthread/timer_create.c: Thread matching now done on
4629         clock type as well as thread attributes.
4630         There are individual global signal-delivering threads for
4631         different clock types.
4632         * sysdeps/pthread/posix-timer.h: Likewise.
4633         * sysdeps/pthread/timer_routines.c: Likewise.
4634
4635         * sysdeps/pthread/timer_routines.c: Thread allocation and
4636         deallocation function now remembers to put thread on active
4637         list and remove from active list.
4638         Thus now the feature of binding multiple timers
4639         to a single thread actually works.
4640
4641 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4642
4643         * pthread.c (__pthread_create_2_1): Optimize a bit.
4644
4645         * internals.h (invalid_handle): Also test for p_terminated != 0.
4646         (nonexisting_handle): New function.  Same as old invalid_handle.
4647         * join.c (pthread_join): Use nonexisting_handle instead of
4648         invalid_handle to test for acceptable thread handle.
4649         * manager.c (pthread_handle_free): Likewise.
4650         * joinrace.c: New file.
4651         Reported by Permaine Cheung <pcheung@cygnus.com>.

4697
4698         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4702
4703         Added missing fork time handling of global libio lock.
4704
4705         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4706         not just the individual stream locks. Rewritten to use new
4707         iterator interface provided by libio rather than accessing
4708         global variable.
4709
4710         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4711         which lock and unlock the stream list using the new interface
4712         provied by libio.
4713         * internals.h: Likewise.
4714
4715         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4716         and __funlockfilelist in the parent after the fork.
4717         Child still calls __fresetlockfiles as before.
4718
4719         * linuxthreads.texi: Now explains what happens to streams at
4720         fork time. Also whole new section on forking and thread added.
4721         Definition of pthread_atfork moved out of Miscellaneous Functions
4722         to this new section.
4723
4724 2000-06-04  Jakub Jelinek  <jakub@redhat.com>

4744         * Makefile (tests): Add ex8.
4745         * Examples/ex8.c: New file.
4746
4747 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4748
4749         Bugfix: The pthread_atfork mechanism now takes care of its
4750         own internal mutex at fork time.
4751
4752         * ptfork.c (__fork): Revised so that the mutex is held across
4753         the fork operation and while the handlers are called, and so that
4754         the child resets the mutex.
4755
4756         * linuxthreads.texi: Updated pthread_atfork documentation to make
4757         it clear that fork and pthread_atfork can't be reentered from
4758         atfork handlers, that pthread_atfork and fork are mutually atomic,
4759         and that the handlers are inherited by the child process.
4760
4761 2000-05-24  Ulrich Drepper  <drepper@redhat.com>
4762
4763         * Makefile (libpthread-routines): Add pspinlock.
4764         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

4786         back to _pthread_fastlock.  Define new pthread_spinlock_t.
4787
4788 2000-05-24  Andreas Jaeger  <aj@suse.de>
4789
4790         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.

4799
4800 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4801
4802         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4803         object state is represented with additional bits which distinguish
4804         whether that state was set up in the current process, or
4805         in an ancestor process. If that state was set in an ancestor,
4806         it means that a fork happened while thread was executing the init
4807         function. In that case, the state is reset to NEVER.
4808         * mutex.c (__pthread_once_fork_prepare): New function.
4809         (__pthread_once_fork_child): Likewise
4810         (__pthread_once_fork_parent): Likewise
4811         (__pthread_reset_pthread_once): Removed.
4812         * ptfork.c (__fork): Call new handlers in mutex.c.
4813         * internals.h: Declarations of new mutex.c functions added.
4814         Declaration of removed function deleted.

4816         to clarify what happens under cancellation and forking.
4817
4818 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4819
4820         * internals.h: New thread manager request type, REQ_KICK.
4821         * join.c (pthread_exit): main thread now calls exit() instead
4822         of _exit() in order to proper process cleanup.
4823         * manager.c (__pthread_manager): Do not terminate manager
4824         after unblocking main thread; wait for main thread's
4825         REQ_PROCESS_EXIT request instead.
4826         Also, added REQ_KICK case to handle new request; this just does
4827         nothing.
4828         * manager.c (pthread_exited): Do not terminate manager after
4829         unblocking main thread.
4830         * manager.c (__pthread_manager_sighandler): If the main thread
4831         is waiting for all other threads to die, send a REQ_KICK into
4832         the thread manager request pipe to get it to clean out the threads
4833         and unblock the main thread as soon as possible. This fixes
4834         the 2000 millisecond hang on shutdown bug.
4835         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4836         including the main one call pthread_exit(), or implicitly do so.
4837         * Makefile (tests): Add ex7.
4838
4839 2000-05-05  Andreas Jaeger  <aj@suse.de>

5266         simultaneously.
5267         * restart.h: Restarts queue even on kernels that don't have
5268         queued real time signals (2.0, early 2.1), thanks to atomic counter,
