4528
4529 2000-06-19  H.J. Lu  <hjl@gnu.org>
4530
4531         * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
4532         HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
4533         (compare_and_swap_with_release_semantics): New. Default to
4534         compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
4535         is not defined.
4536
4537         * spinlock.c (__pthread_unlock): Call
4538         compare_and_swap_with_release_semantics () instead of

4542
4543         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning

4550 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4551
4552         Timer nodes are now reference counted, and can be marked
4553         as deleted. This allows for the safe release of the global mutex
4554         in the middle without losing the timer being operated on.
4555
4556         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4557         member is now an enum with three values, so that an intermediate
4558         state can be represented (deleted but not free for reuse yet).
4559         New refcount member added.
4560         * sysdeps/pthread/timer_routines.c: Likewise.
4561
4562         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,

4564
4565         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4566         restructured, recursive deadlock bug fixed.
4567
4568         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4569         timer_addref to ensure that timer won't be deleted while mutex is not
4570         held. Also uses timer_invalid to perform validation of timer handle.
4571         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4572         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4573
4574 2000-06-14  Ulrich Drepper  <drepper@redhat.com>

4579 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4580
4581         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4582         tightened up some critical regions and micro-optimized some list
4583         manipulation code.
4584
4585         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4586         Returns int value now to indicate whether timer was queued at head.
4587         * sysdeps/pthread/posix-timer.h: Likewise.
4588         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4589         new return value from __timer_thread_queue_timer to avoid waking
4590         up timer thread unnecessarily.
4591
4592         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4593         inuse flag, because this requires mutex to be held.  Callers updated
4594         to do the check when they have the mutex.
4595         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4596
4597         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4598         regions: avoids making system calls while holding timer mutex, and
4599         a few computations were moved outside of the mutex as well.
4600         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4601
4602         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4603         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4604         changed to get better better code out of gcc.
4605         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4606         version of list_unlink added here.
4607         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4608         function in all places: idempotent one for timers, non-idempotent
4609         one for thread nodes.
4610         * sysdeps/pthread/timer_settime: Likewise.
4611         * sysdeps/pthread/timer_routines.c: Likewise.
4612
4613 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4614
4615         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4630         * Examples/ex6.c: Test return value of pthread_join.
4631
4632 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4633
4634         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4635         (__pthread_spin_trylock): Implement.
4636         (__pthread_spin_unlock): Implement.
4637         (__pthread_spin_init): Implement.
4638         (__pthread_spin_destroy): Implement.
4639
4640 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4641
4642         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4643         really append the entry.

4649 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4650
4651         * sysdeps/pthread/timer_create.c: Thread matching now done on
4652         clock type as well as thread attributes.
4653         There are individual global signal-delivering threads for
4654         different clock types.
4655         * sysdeps/pthread/posix-timer.h: Likewise.
4656         * sysdeps/pthread/timer_routines.c: Likewise.
4657
4658         * sysdeps/pthread/timer_routines.c: Thread allocation and
4659         deallocation function now remembers to put thread on active
4660         list and remove from active list.
4661         Thus now the feature of binding multiple timers
4662         to a single thread actually works.
4663

4671         invalid_handle to test for acceptable thread handle.
4672         * manager.c (pthread_handle_free): Likewise.
4673         * joinrace.c: New file.
4674         Reported by Permaine Cheung <pcheung@cygnus.com>.

4727
4728         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4729         not just the individual stream locks. Rewritten to use new

4731         global variable.
4732
4733         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4734         which lock and unlock the stream list using the new interface

4740         Child still calls __fresetlockfiles as before.
4741
4742         * linuxthreads.texi: Now explains what happens to streams at
4743         fork time. Also whole new section on forking and thread added.
4744         Definition of pthread_atfork moved out of Miscellaneous Functions
4745         to this new section.

4771
4772         Bugfix: The pthread_atfork mechanism now takes care of its
4773         own internal mutex at fork time.
4774
4775         * ptfork.c (__fork): Revised so that the mutex is held across
4776         the fork operation and while the handlers are called, and so that

4778
4779         * linuxthreads.texi: Updated pthread_atfork documentation to make
4780         it clear that fork and pthread_atfork can't be reentered from

4827         whether that state was set up in the current process, or
4828         in an ancestor process. If that state was set in an ancestor,
4829         it means that a fork happened while thread was executing the init
4830         function. In that case, the state is reset to NEVER.
4831         * mutex.c (__pthread_once_fork_prepare): New function.

4842
4843         * internals.h: New thread manager request type, REQ_KICK.
4844         * join.c (pthread_exit): main thread now calls exit() instead
4845         of _exit() in order to proper process cleanup.
4846         * manager.c (__pthread_manager): Do not terminate manager
4847         after unblocking main thread; wait for main thread's

5289         simultaneously.
5290         * restart.h: Restarts queue even on kernels that don't have
5291         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5292         avoiding a rare race condition in pthread_cond_timedwait.
