4493         * sysdeps/pthread/bits/pthreadtypes.h: Likewise.
4494         Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
4495
4496 2000-06-19  H.J. Lu  <hjl@gnu.org>
4497
4498         * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
4499         HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
4500         (compare_and_swap_with_release_semantics): New. Default to
4501         compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
4502         is not defined.
4503
4504         * spinlock.c (__pthread_unlock): Call
4505         compare_and_swap_with_release_semantics () instead of
4506         compare_and_swap ().
4507
4508 2000-06-19  Ulrich Drepper  <drepper@redhat.com>
4509
4510         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning
4511         to errno directly.
4512         * sysdeps/pthread/timer_delete.c: Likewise.
4513         * sysdeps/pthread/timer_getoverr.c: Likewise.
4514         * sysdeps/pthread/timer_gettime.c: Likewise.
4515         * sysdeps/pthread/timer_settime.c: Likewise.
4516
4517 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4518
4519         Timer nodes are now reference counted, and can be marked
4520         as deleted. This allows for the safe release of the global mutex
4521         in the middle without losing the timer being operated on.
4522
4523         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4524         member is now an enum with three values, so that an intermediate
4525         state can be represented (deleted but not free for reuse yet).
4526         New refcount member added.
4527         * sysdeps/pthread/timer_routines.c: Likewise.
4528
4529         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4530         timer_valid): New inline functions added.
4531
4532         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4533         restructured, recursive deadlock bug fixed.
4534
4535         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4536         timer_addref to ensure that timer won't be deleted while mutex is not
4537         held. Also uses timer_invalid to perform validation of timer handle.
4538         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4539         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4540
4541 2000-06-14  Ulrich Drepper  <drepper@redhat.com>

4543         * shlib-versions: Add entry for SH.
4544         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4545
4546 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4547
4548         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4549         tightened up some critical regions and micro-optimized some list
4550         manipulation code.
4551
4552         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4553         Returns int value now to indicate whether timer was queued at head.
4554         * sysdeps/pthread/posix-timer.h: Likewise.
4555         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4556         new return value from __timer_thread_queue_timer to avoid waking
4557         up timer thread unnecessarily.
4558
4559         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4560         inuse flag, because this requires mutex to be held.  Callers updated
4561         to do the check when they have the mutex.
4562         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4563
4564         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4565         regions: avoids making system calls while holding timer mutex, and
4566         a few computations were moved outside of the mutex as well.
4567         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4568
4569         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4570         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4571         changed to get better better code out of gcc.
4572         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4573         version of list_unlink added here.
4574         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4575         function in all places: idempotent one for timers, non-idempotent
4576         one for thread nodes.
4577         * sysdeps/pthread/timer_settime: Likewise.
4578         * sysdeps/pthread/timer_routines.c: Likewise.
4579
4580 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4581
4582         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4595         * Makefile (tests): Add joinrace.
4596
4597         * Examples/ex6.c: Test return value of pthread_join.
4598
4599 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4600
4601         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4602         (__pthread_spin_trylock): Implement.
4603         (__pthread_spin_unlock): Implement.
4604         (__pthread_spin_init): Implement.
4605         (__pthread_spin_destroy): Implement.
4606
4607 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4608
4609         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4610         really append the entry.
4611
4612 2000-06-10  Andreas Jaeger  <aj@suse.de>

4615
4616 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4617
4618         * sysdeps/pthread/timer_create.c: Thread matching now done on
4619         clock type as well as thread attributes.
4620         There are individual global signal-delivering threads for
4621         different clock types.
4622         * sysdeps/pthread/posix-timer.h: Likewise.
4623         * sysdeps/pthread/timer_routines.c: Likewise.
4624
4625         * sysdeps/pthread/timer_routines.c: Thread allocation and
4626         deallocation function now remembers to put thread on active
4627         list and remove from active list.
4628         Thus now the feature of binding multiple timers
4629         to a single thread actually works.
4630
4631 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4632
4633         * pthread.c (__pthread_create_2_1): Optimize a bit.
4634
4635         * internals.h (invalid_handle): Also test for p_terminated != 0.
4636         (nonexisting_handle): New function.  Same as old invalid_handle.
4637         * join.c (pthread_join): Use nonexisting_handle instead of
4638         invalid_handle to test for acceptable thread handle.
4639         * manager.c (pthread_handle_free): Likewise.
4640         * joinrace.c: New file.
4641         Reported by Permaine Cheung <pcheung@cygnus.com>.

4687
4688         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4692
4693         Added missing fork time handling of global libio lock.
4694
4695         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4696         not just the individual stream locks. Rewritten to use new
4697         iterator interface provided by libio rather than accessing
4698         global variable.
4699
4700         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4701         which lock and unlock the stream list using the new interface
4702         provied by libio.
4703         * internals.h: Likewise.
4704
4705         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4706         and __funlockfilelist in the parent after the fork.
4707         Child still calls __fresetlockfiles as before.
4708
4709         * linuxthreads.texi: Now explains what happens to streams at
4710         fork time. Also whole new section on forking and thread added.
4711         Definition of pthread_atfork moved out of Miscellaneous Functions
4712         to this new section.
4713
4714 2000-06-04  Jakub Jelinek  <jakub@redhat.com>

4734         * Makefile (tests): Add ex8.
4735         * Examples/ex8.c: New file.
4736
4737 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4738
4739         Bugfix: The pthread_atfork mechanism now takes care of its
4740         own internal mutex at fork time.
4741
4742         * ptfork.c (__fork): Revised so that the mutex is held across
4743         the fork operation and while the handlers are called, and so that
4744         the child resets the mutex.
4745
4746         * linuxthreads.texi: Updated pthread_atfork documentation to make
4747         it clear that fork and pthread_atfork can't be reentered from
4748         atfork handlers, that pthread_atfork and fork are mutually atomic,
4749         and that the handlers are inherited by the child process.
4750
4751 2000-05-24  Ulrich Drepper  <drepper@redhat.com>
4752
4753         * Makefile (libpthread-routines): Add pspinlock.
4754         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

4776         back to _pthread_fastlock.  Define new pthread_spinlock_t.
4777
4778 2000-05-24  Andreas Jaeger  <aj@suse.de>
4779
4780         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.

4789
4790 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4791
4792         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4793         object state is represented with additional bits which distinguish
4794         whether that state was set up in the current process, or
4795         in an ancestor process. If that state was set in an ancestor,
4796         it means that a fork happened while thread was executing the init
4797         function. In that case, the state is reset to NEVER.
4798         * mutex.c (__pthread_once_fork_prepare): New function.
4799         (__pthread_once_fork_child): Likewise
4800         (__pthread_once_fork_parent): Likewise
4801         (__pthread_reset_pthread_once): Removed.
4802         * ptfork.c (__fork): Call new handlers in mutex.c.
4803         * internals.h: Declarations of new mutex.c functions added.
4804         Declaration of removed function deleted.

4806         to clarify what happens under cancellation and forking.
4807
4808 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4809
4810         * internals.h: New thread manager request type, REQ_KICK.
4811         * join.c (pthread_exit): main thread now calls exit() instead
4812         of _exit() in order to proper process cleanup.
4813         * manager.c (__pthread_manager): Do not terminate manager
4814         after unblocking main thread; wait for main thread's
4815         REQ_PROCESS_EXIT request instead.
4816         Also, added REQ_KICK case to handle new request; this just does
4817         nothing.
4818         * manager.c (pthread_exited): Do not terminate manager after
4819         unblocking main thread.
4820         * manager.c (__pthread_manager_sighandler): If the main thread
4821         is waiting for all other threads to die, send a REQ_KICK into
4822         the thread manager request pipe to get it to clean out the threads
4823         and unblock the main thread as soon as possible. This fixes
4824         the 2000 millisecond hang on shutdown bug.
4825         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4826         including the main one call pthread_exit(), or implicitly do so.
4827         * Makefile (tests): Add ex7.
4828
4829 2000-05-05  Andreas Jaeger  <aj@suse.de>
4830
4831         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c

5256         simultaneously.
5257         * restart.h: Restarts queue even on kernels that don't have
5258         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5259         avoiding a rare race condition in pthread_cond_timedwait.
