4491         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4492
4493 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4494
4495         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4496         tightened up some critical regions and micro-optimized some list
4497         manipulation code.
4498
4499         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4500         Returns int value now to indicate whether timer was queued at head.
4501         * sysdeps/pthread/posix-timer.h: Likewise.
4502         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4503         new return value from __timer_thread_queue_timer to avoid waking
4504         up timer thread unnecessarily.
4505
4506         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4507         inuse flag, because this requires mutex to be held.  Callers updated
4508         to do the check when they have the mutex.
4509         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4510
4511         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4512         regions: avoids making system calls while holding timer mutex, and
4513         a few computations were moved outside of the mutex as well.
4514         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4515
4516         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4517         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4518         changed to get better better code out of gcc.
4519         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4520         version of list_unlink added here.
4521         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4522         function in all places: idempotent one for timers, non-idempotent
4523         one for thread nodes.
4524         * sysdeps/pthread/timer_settime: Likewise.
4525         * sysdeps/pthread/timer_routines.c: Likewise.
4526
4527 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4528
4529         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
4530         * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.

4543
4544         * Examples/ex6.c: Test return value of pthread_join.
4545
4546 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4547
4548         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4549         (__pthread_spin_trylock): Implement.
4550         (__pthread_spin_unlock): Implement.
4551         (__pthread_spin_init): Implement.
4552         (__pthread_spin_destroy): Implement.
4553
4554 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4555
4556         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4557         really append the entry.
4558
4559 2000-06-10  Andreas Jaeger  <aj@suse.de>

4562
4563 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4564
4565         * sysdeps/pthread/timer_create.c: Thread matching now done on
4566         clock type as well as thread attributes.
4567         There are individual global signal-delivering threads for
4568         different clock types.
4569         * sysdeps/pthread/posix-timer.h: Likewise.
4570         * sysdeps/pthread/timer_routines.c: Likewise.
4571
4572         * sysdeps/pthread/timer_routines.c: Thread allocation and
4573         deallocation function now remembers to put thread on active
4574         list and remove from active list.
4575         Thus now the feature of binding multiple timers
4576         to a single thread actually works.
4577

4584         * join.c (pthread_join): Use nonexisting_handle instead of
4585         invalid_handle to test for acceptable thread handle.
4586         * manager.c (pthread_handle_free): Likewise.
4587         * joinrace.c: New file.
4588         Reported by Permaine Cheung <pcheung@cygnus.com>.

4634
4635         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4639
4640         Added missing fork time handling of global libio lock.
4641
4642         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4643         not just the individual stream locks. Rewritten to use new
4644         iterator interface provided by libio rather than accessing
4645         global variable.
4646
4647         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4648         which lock and unlock the stream list using the new interface
4649         provied by libio.

4651
4652         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4653         and __funlockfilelist in the parent after the fork.
4654         Child still calls __fresetlockfiles as before.
4655
4656         * linuxthreads.texi: Now explains what happens to streams at
4657         fork time. Also whole new section on forking and thread added.
4658         Definition of pthread_atfork moved out of Miscellaneous Functions
4659         to this new section.

4684 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4685
4686         Bugfix: The pthread_atfork mechanism now takes care of its
4687         own internal mutex at fork time.
4688
4689         * ptfork.c (__fork): Revised so that the mutex is held across
4690         the fork operation and while the handlers are called, and so that
4691         the child resets the mutex.
4692
4693         * linuxthreads.texi: Updated pthread_atfork documentation to make
4694         it clear that fork and pthread_atfork can't be reentered from
4695         atfork handlers, that pthread_atfork and fork are mutually atomic,
4696         and that the handlers are inherited by the child process.

4740         object state is represented with additional bits which distinguish
4741         whether that state was set up in the current process, or
4742         in an ancestor process. If that state was set in an ancestor,
4743         it means that a fork happened while thread was executing the init
4744         function. In that case, the state is reset to NEVER.
4745         * mutex.c (__pthread_once_fork_prepare): New function.
4746         (__pthread_once_fork_child): Likewise
4747         (__pthread_once_fork_parent): Likewise
4748         (__pthread_reset_pthread_once): Removed.

4756
4757         * internals.h: New thread manager request type, REQ_KICK.
4758         * join.c (pthread_exit): main thread now calls exit() instead
4759         of _exit() in order to proper process cleanup.
4760         * manager.c (__pthread_manager): Do not terminate manager
4761         after unblocking main thread; wait for main thread's
4762         REQ_PROCESS_EXIT request instead.
4763         Also, added REQ_KICK case to handle new request; this just does
4764         nothing.
4765         * manager.c (pthread_exited): Do not terminate manager after
4766         unblocking main thread.
4767         * manager.c (__pthread_manager_sighandler): If the main thread
4768         is waiting for all other threads to die, send a REQ_KICK into
4769         the thread manager request pipe to get it to clean out the threads
4770         and unblock the main thread as soon as possible. This fixes
4771         the 2000 millisecond hang on shutdown bug.
4772         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4773         including the main one call pthread_exit(), or implicitly do so.
4774         * Makefile (tests): Add ex7.
4775
4776 2000-05-05  Andreas Jaeger  <aj@suse.de>

4806
4807         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
4808         now.  First gcc must be fixed (more concrete: libgcc).

4819
4820         * join.c (pthread_exit): Set p_terminated after reporting the
4821         termination event instead of before.

5192         Redesigned how cancellation unblocks a thread from internal
5193         cancellation points (sem_wait, pthread_join,
5194         pthread_cond_{wait,timedwait}).
5195         Cancellation won't eat a signal in any of these functions
5196         (*required* by POSIX and Single Unix Spec!).
5197         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5198         simultaneous condition variable signal (not required by POSIX
5199         or Single Unix Spec, but nice).
5200         * spinlock.c: __pthread_lock queues back any received restarts
5201         that don't belong to it instead of assuming ownership of lock
5202         upon any restart; fastlock can no longer be acquired by two threads
5203         simultaneously.
5204         * restart.h: Restarts queue even on kernels that don't have
5205         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5206         avoiding a rare race condition in pthread_cond_timedwait.
