4143         change guardpage access.
4144         * sysdeps/i386/useldt.h: Define FLOATING_STACKS and

4499         * sysdeps/unix/sysv/linux/bits/posix_opt.h: Define _POSIX_BARRIERS.
4500         * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.
4501

4503         (tests): Add ex9.  Add rule to build ex9.
4504         * Versions: Export barrier functions.
4505         * barrier.c: New file.

4508         * sysdeps/pthread/bits/pthreadtypes.h: Likewise.
4509         Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
4510
4511 2000-06-19  H.J. Lu  <hjl@gnu.org>
4512
4513         * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
4514         HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
4515         (compare_and_swap_with_release_semantics): New. Default to
4516         compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
4517         is not defined.
4518
4519         * spinlock.c (__pthread_unlock): Call
4520         compare_and_swap_with_release_semantics () instead of
4521         compare_and_swap ().
4522
4523 2000-06-19  Ulrich Drepper  <drepper@redhat.com>
4524
4525         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning
4526         to errno directly.

4528         * sysdeps/pthread/timer_getoverr.c: Likewise.
4529         * sysdeps/pthread/timer_gettime.c: Likewise.
4530         * sysdeps/pthread/timer_settime.c: Likewise.
4531
4532 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4533
4534         Timer nodes are now reference counted, and can be marked
4535         as deleted. This allows for the safe release of the global mutex
4536         in the middle without losing the timer being operated on.
4537
4538         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4539         member is now an enum with three values, so that an intermediate
4540         state can be represented (deleted but not free for reuse yet).
4541         New refcount member added.
4542         * sysdeps/pthread/timer_routines.c: Likewise.
4543
4544         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4545         timer_valid): New inline functions added.
4546
4547         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4548         restructured, recursive deadlock bug fixed.
4549
4550         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4551         timer_addref to ensure that timer won't be deleted while mutex is not
4552         held. Also uses timer_invalid to perform validation of timer handle.
4553         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4554         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4555
4556 2000-06-14  Ulrich Drepper  <drepper@redhat.com>

4560
4561 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4562
4563         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4564         tightened up some critical regions and micro-optimized some list
4565         manipulation code.
4566
4567         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4568         Returns int value now to indicate whether timer was queued at head.
4569         * sysdeps/pthread/posix-timer.h: Likewise.
4570         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4571         new return value from __timer_thread_queue_timer to avoid waking
4572         up timer thread unnecessarily.
4573
4574         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4575         inuse flag, because this requires mutex to be held.  Callers updated
4576         to do the check when they have the mutex.
4577         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4578
4579         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4580         regions: avoids making system calls while holding timer mutex, and
4581         a few computations were moved outside of the mutex as well.
4582         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4583
4584         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4585         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4586         changed to get better better code out of gcc.
4587         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4588         version of list_unlink added here.
4589         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4590         function in all places: idempotent one for timers, non-idempotent
4591         one for thread nodes.
4592         * sysdeps/pthread/timer_settime: Likewise.
4593         * sysdeps/pthread/timer_routines.c: Likewise.
4594
4595 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4596
4597         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4610         * Makefile (tests): Add joinrace.
4611
4612         * Examples/ex6.c: Test return value of pthread_join.
4613
4614 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4615
4616         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4617         (__pthread_spin_trylock): Implement.
4618         (__pthread_spin_unlock): Implement.
4619         (__pthread_spin_init): Implement.
4620         (__pthread_spin_destroy): Implement.
4621
4622 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4623
4624         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4625         really append the entry.

4630
4631 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4632
4633         * sysdeps/pthread/timer_create.c: Thread matching now done on
4634         clock type as well as thread attributes.
4635         There are individual global signal-delivering threads for
4636         different clock types.
4637         * sysdeps/pthread/posix-timer.h: Likewise.
4638         * sysdeps/pthread/timer_routines.c: Likewise.
4639
4640         * sysdeps/pthread/timer_routines.c: Thread allocation and
4641         deallocation function now remembers to put thread on active
4642         list and remove from active list.
4643         Thus now the feature of binding multiple timers
4644         to a single thread actually works.
4645
4646 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4647
4648         * pthread.c (__pthread_create_2_1): Optimize a bit.
4649
4650         * internals.h (invalid_handle): Also test for p_terminated != 0.
4651         (nonexisting_handle): New function.  Same as old invalid_handle.
4652         * join.c (pthread_join): Use nonexisting_handle instead of
4653         invalid_handle to test for acceptable thread handle.
4654         * manager.c (pthread_handle_free): Likewise.
4655         * joinrace.c: New file.
4656         Reported by Permaine Cheung <pcheung@cygnus.com>.

4702
4703         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4707
4708         Added missing fork time handling of global libio lock.
4709
4710         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4711         not just the individual stream locks. Rewritten to use new
4712         iterator interface provided by libio rather than accessing
4713         global variable.
4714
4715         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4716         which lock and unlock the stream list using the new interface
4717         provied by libio.
4718         * internals.h: Likewise.
4719
4720         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4721         and __funlockfilelist in the parent after the fork.
4722         Child still calls __fresetlockfiles as before.
4723
4724         * linuxthreads.texi: Now explains what happens to streams at
4725         fork time. Also whole new section on forking and thread added.
4726         Definition of pthread_atfork moved out of Miscellaneous Functions
4727         to this new section.
4728
4729 2000-06-04  Jakub Jelinek  <jakub@redhat.com>

4749         * Makefile (tests): Add ex8.
4750         * Examples/ex8.c: New file.
4751
4752 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4753
4754         Bugfix: The pthread_atfork mechanism now takes care of its
4755         own internal mutex at fork time.
4756
4757         * ptfork.c (__fork): Revised so that the mutex is held across
4758         the fork operation and while the handlers are called, and so that
4759         the child resets the mutex.
4760
4761         * linuxthreads.texi: Updated pthread_atfork documentation to make
4762         it clear that fork and pthread_atfork can't be reentered from
4763         atfork handlers, that pthread_atfork and fork are mutually atomic,
4764         and that the handlers are inherited by the child process.
4765
4766 2000-05-24  Ulrich Drepper  <drepper@redhat.com>
4767
4768         * Makefile (libpthread-routines): Add pspinlock.
4769         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.
4770         Use struct _pthread_fastlock instead of pthread_spinlock_t.

4791         back to _pthread_fastlock.  Define new pthread_spinlock_t.
4792
4793 2000-05-24  Andreas Jaeger  <aj@suse.de>
4794
4795         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.

4804
4805 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4806
4807         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4808         object state is represented with additional bits which distinguish
4809         whether that state was set up in the current process, or
4810         in an ancestor process. If that state was set in an ancestor,
4811         it means that a fork happened while thread was executing the init
4812         function. In that case, the state is reset to NEVER.
4813         * mutex.c (__pthread_once_fork_prepare): New function.
4814         (__pthread_once_fork_child): Likewise
4815         (__pthread_once_fork_parent): Likewise
4816         (__pthread_reset_pthread_once): Removed.
4817         * ptfork.c (__fork): Call new handlers in mutex.c.
4818         * internals.h: Declarations of new mutex.c functions added.
4819         Declaration of removed function deleted.

4821         to clarify what happens under cancellation and forking.
4822
4823 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4824
4825         * internals.h: New thread manager request type, REQ_KICK.
4826         * join.c (pthread_exit): main thread now calls exit() instead
4827         of _exit() in order to proper process cleanup.
4828         * manager.c (__pthread_manager): Do not terminate manager
4829         after unblocking main thread; wait for main thread's
4830         REQ_PROCESS_EXIT request instead.
4831         Also, added REQ_KICK case to handle new request; this just does
4832         nothing.
4833         * manager.c (pthread_exited): Do not terminate manager after
4834         unblocking main thread.
4835         * manager.c (__pthread_manager_sighandler): If the main thread
4836         is waiting for all other threads to die, send a REQ_KICK into
4837         the thread manager request pipe to get it to clean out the threads
4838         and unblock the main thread as soon as possible. This fixes
4839         the 2000 millisecond hang on shutdown bug.
4840         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4841         including the main one call pthread_exit(), or implicitly do so.

5271         simultaneously.
5272         * restart.h: Restarts queue even on kernels that don't have
5273         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5274         avoiding a rare race condition in pthread_cond_timedwait.
