4489         * sysdeps/pthread/bits/pthreadtypes.h: Likewise.
4490         Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
4491
4492 2000-06-19  H.J. Lu  <hjl@gnu.org>
4493
4494         * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
4495         HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
4496         (compare_and_swap_with_release_semantics): New. Default to
4497         compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
4498         is not defined.
4499
4500         * spinlock.c (__pthread_unlock): Call
4501         compare_and_swap_with_release_semantics () instead of
4502         compare_and_swap ().
4503
4504 2000-06-19  Ulrich Drepper  <drepper@redhat.com>
4505
4506         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning
4507         to errno directly.
4508         * sysdeps/pthread/timer_delete.c: Likewise.
4509         * sysdeps/pthread/timer_getoverr.c: Likewise.
4510         * sysdeps/pthread/timer_gettime.c: Likewise.
4511         * sysdeps/pthread/timer_settime.c: Likewise.
4512
4513 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4514
4515         Timer nodes are now reference counted, and can be marked
4516         as deleted. This allows for the safe release of the global mutex
4517         in the middle without losing the timer being operated on.
4518
4519         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4520         member is now an enum with three values, so that an intermediate
4521         state can be represented (deleted but not free for reuse yet).
4522         New refcount member added.
4523         * sysdeps/pthread/timer_routines.c: Likewise.
4524
4525         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4526         timer_valid): New inline functions added.
4527
4528         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4529         restructured, recursive deadlock bug fixed.
4530
4531         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4532         timer_addref to ensure that timer won't be deleted while mutex is not
4533         held. Also uses timer_invalid to perform validation of timer handle.
4534         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4535         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4536
4537 2000-06-14  Ulrich Drepper  <drepper@redhat.com>
4538
4539         * shlib-versions: Add entry for SH.
4540         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4541
4542 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4543
4544         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4545         tightened up some critical regions and micro-optimized some list
4546         manipulation code.
4547
4548         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4549         Returns int value now to indicate whether timer was queued at head.
4550         * sysdeps/pthread/posix-timer.h: Likewise.
4551         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4552         new return value from __timer_thread_queue_timer to avoid waking
4553         up timer thread unnecessarily.
4554
4555         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4556         inuse flag, because this requires mutex to be held.  Callers updated
4557         to do the check when they have the mutex.
4558         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4559
4560         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4561         regions: avoids making system calls while holding timer mutex, and
4562         a few computations were moved outside of the mutex as well.
4563         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4564
4565         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4566         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4567         changed to get better better code out of gcc.
4568         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4569         version of list_unlink added here.
4570         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4571         function in all places: idempotent one for timers, non-idempotent
4572         one for thread nodes.
4573         * sysdeps/pthread/timer_settime: Likewise.
4574         * sysdeps/pthread/timer_routines.c: Likewise.
4575
4576 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4577
4578         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4591         * Makefile (tests): Add joinrace.
4592
4593         * Examples/ex6.c: Test return value of pthread_join.
4594
4595 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4596
4597         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4598         (__pthread_spin_trylock): Implement.
4599         (__pthread_spin_unlock): Implement.
4600         (__pthread_spin_init): Implement.
4601         (__pthread_spin_destroy): Implement.
4602
4603 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4604
4605         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4606         really append the entry.
4607
4608 2000-06-10  Andreas Jaeger  <aj@suse.de>

4611
4612 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4613
4614         * sysdeps/pthread/timer_create.c: Thread matching now done on
4615         clock type as well as thread attributes.
4616         There are individual global signal-delivering threads for
4617         different clock types.
4618         * sysdeps/pthread/posix-timer.h: Likewise.
4619         * sysdeps/pthread/timer_routines.c: Likewise.
4620
4621         * sysdeps/pthread/timer_routines.c: Thread allocation and
4622         deallocation function now remembers to put thread on active
4623         list and remove from active list.
4624         Thus now the feature of binding multiple timers
4625         to a single thread actually works.
4626
4627 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4628
4629         * pthread.c (__pthread_create_2_1): Optimize a bit.
4630
4631         * internals.h (invalid_handle): Also test for p_terminated != 0.
4632         (nonexisting_handle): New function.  Same as old invalid_handle.
4633         * join.c (pthread_join): Use nonexisting_handle instead of
4634         invalid_handle to test for acceptable thread handle.
4635         * manager.c (pthread_handle_free): Likewise.
4636         * joinrace.c: New file.
4637         Reported by Permaine Cheung <pcheung@cygnus.com>.

4683
4684         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4688
4689         Added missing fork time handling of global libio lock.
4690
4691         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4692         not just the individual stream locks. Rewritten to use new
4693         iterator interface provided by libio rather than accessing
4694         global variable.
4695
4696         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4697         which lock and unlock the stream list using the new interface
4698         provied by libio.
4699         * internals.h: Likewise.
4700
4701         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4702         and __funlockfilelist in the parent after the fork.
4703         Child still calls __fresetlockfiles as before.
4704
4705         * linuxthreads.texi: Now explains what happens to streams at
4706         fork time. Also whole new section on forking and thread added.
4707         Definition of pthread_atfork moved out of Miscellaneous Functions
4708         to this new section.
4709
4710 2000-06-04  Jakub Jelinek  <jakub@redhat.com>

4730         * Makefile (tests): Add ex8.
4731         * Examples/ex8.c: New file.
4732
4733 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4734
4735         Bugfix: The pthread_atfork mechanism now takes care of its
4736         own internal mutex at fork time.
4737
4738         * ptfork.c (__fork): Revised so that the mutex is held across
4739         the fork operation and while the handlers are called, and so that
4740         the child resets the mutex.
4741
4742         * linuxthreads.texi: Updated pthread_atfork documentation to make
4743         it clear that fork and pthread_atfork can't be reentered from
4744         atfork handlers, that pthread_atfork and fork are mutually atomic,
4745         and that the handlers are inherited by the child process.
4746
4747 2000-05-24  Ulrich Drepper  <drepper@redhat.com>
4748
4749         * Makefile (libpthread-routines): Add pspinlock.
4750         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

4772         back to _pthread_fastlock.  Define new pthread_spinlock_t.
4773
4774 2000-05-24  Andreas Jaeger  <aj@suse.de>
4775
4776         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.

4785
4786 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4787
4788         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4789         object state is represented with additional bits which distinguish
4790         whether that state was set up in the current process, or
4791         in an ancestor process. If that state was set in an ancestor,
4792         it means that a fork happened while thread was executing the init
4793         function. In that case, the state is reset to NEVER.
4794         * mutex.c (__pthread_once_fork_prepare): New function.
4795         (__pthread_once_fork_child): Likewise
4796         (__pthread_once_fork_parent): Likewise
4797         (__pthread_reset_pthread_once): Removed.
4798         * ptfork.c (__fork): Call new handlers in mutex.c.
4799         * internals.h: Declarations of new mutex.c functions added.
4800         Declaration of removed function deleted.

4802         to clarify what happens under cancellation and forking.
4803
4804 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4805
4806         * internals.h: New thread manager request type, REQ_KICK.
4807         * join.c (pthread_exit): main thread now calls exit() instead
4808         of _exit() in order to proper process cleanup.
4809         * manager.c (__pthread_manager): Do not terminate manager
4810         after unblocking main thread; wait for main thread's
4811         REQ_PROCESS_EXIT request instead.
4812         Also, added REQ_KICK case to handle new request; this just does
4813         nothing.
4814         * manager.c (pthread_exited): Do not terminate manager after
4815         unblocking main thread.
4816         * manager.c (__pthread_manager_sighandler): If the main thread
4817         is waiting for all other threads to die, send a REQ_KICK into
4818         the thread manager request pipe to get it to clean out the threads
4819         and unblock the main thread as soon as possible. This fixes
4820         the 2000 millisecond hang on shutdown bug.
4821         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4822         including the main one call pthread_exit(), or implicitly do so.
4823         * Makefile (tests): Add ex7.
4824
4825 2000-05-05  Andreas Jaeger  <aj@suse.de>
4826
4827         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c

5252         simultaneously.
5253         * restart.h: Restarts queue even on kernels that don't have
5254         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5255         avoiding a rare race condition in pthread_cond_timedwait.
