4844         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4845
4846 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4847
4848         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4849         tightened up some critical regions and micro-optimized some list
4850         manipulation code.
4851
4852         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4853         Returns int value now to indicate whether timer was queued at head.
4854         * sysdeps/pthread/posix-timer.h: Likewise.
4855         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4856         new return value from __timer_thread_queue_timer to avoid waking
4857         up timer thread unnecessarily.
4858
4859         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4860         inuse flag, because this requires mutex to be held.  Callers updated
4861         to do the check when they have the mutex.
4862         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4863
4864         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4865         regions: avoids making system calls while holding timer mutex, and
4866         a few computations were moved outside of the mutex as well.
4867         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4868
4869         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4870         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4871         changed to get better better code out of gcc.
4872         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4873         version of list_unlink added here.
4874         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4875         function in all places: idempotent one for timers, non-idempotent
4876         one for thread nodes.
4877         * sysdeps/pthread/timer_settime: Likewise.
4878         * sysdeps/pthread/timer_routines.c: Likewise.
4879
4880 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4881
4882         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
4883         * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.
4884

4895         * Makefile (tests): Add joinrace.
4896
4897         * Examples/ex6.c: Test return value of pthread_join.
4898
4899 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4900
4901         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4902         (__pthread_spin_trylock): Implement.
4903         (__pthread_spin_unlock): Implement.
4904         (__pthread_spin_init): Implement.
4905         (__pthread_spin_destroy): Implement.
4906
4907 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4908
4909         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4910         really append the entry.

4915
4916 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4917
4918         * sysdeps/pthread/timer_create.c: Thread matching now done on
4919         clock type as well as thread attributes.
4920         There are individual global signal-delivering threads for
4921         different clock types.
4922         * sysdeps/pthread/posix-timer.h: Likewise.
4923         * sysdeps/pthread/timer_routines.c: Likewise.
4924
4925         * sysdeps/pthread/timer_routines.c: Thread allocation and
4926         deallocation function now remembers to put thread on active
4927         list and remove from active list.
4928         Thus now the feature of binding multiple timers
4929         to a single thread actually works.
4930

4932
4933         * pthread.c (__pthread_create_2_1): Optimize a bit.

4937         * join.c (pthread_join): Use nonexisting_handle instead of
4938         invalid_handle to test for acceptable thread handle.
4939         * manager.c (pthread_handle_free): Likewise.
4940         * joinrace.c: New file.
4941         Reported by Permaine Cheung <pcheung@cygnus.com>.

4987
4988         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4992
4993         Added missing fork time handling of global libio lock.
4994
4995         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4996         not just the individual stream locks. Rewritten to use new
4997         iterator interface provided by libio rather than accessing
4998         global variable.
4999
5000         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
5001         which lock and unlock the stream list using the new interface
5002         provied by libio.

5004
5005         * ptfork.c (__fork): Now calls __flockfilelist before fork,
5006         and __funlockfilelist in the parent after the fork.
5007         Child still calls __fresetlockfiles as before.
5008
5009         * linuxthreads.texi: Now explains what happens to streams at
5010         fork time. Also whole new section on forking and thread added.
5011         Definition of pthread_atfork moved out of Miscellaneous Functions
5012         to this new section.

5037 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
5038
5039         Bugfix: The pthread_atfork mechanism now takes care of its
5040         own internal mutex at fork time.
5041
5042         * ptfork.c (__fork): Revised so that the mutex is held across
5043         the fork operation and while the handlers are called, and so that
5044         the child resets the mutex.
5045
5046         * linuxthreads.texi: Updated pthread_atfork documentation to make
5047         it clear that fork and pthread_atfork can't be reentered from
5048         atfork handlers, that pthread_atfork and fork are mutually atomic,
5049         and that the handlers are inherited by the child process.

5092         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
5093         object state is represented with additional bits which distinguish
5094         whether that state was set up in the current process, or
5095         in an ancestor process. If that state was set in an ancestor,
5096         it means that a fork happened while thread was executing the init
5097         function. In that case, the state is reset to NEVER.
5098         * mutex.c (__pthread_once_fork_prepare): New function.
5099         (__pthread_once_fork_child): Likewise
5100         (__pthread_once_fork_parent): Likewise
5101         (__pthread_reset_pthread_once): Removed.

5109
5110         * internals.h: New thread manager request type, REQ_KICK.
5111         * join.c (pthread_exit): main thread now calls exit() instead
5112         of _exit() in order to proper process cleanup.
5113         * manager.c (__pthread_manager): Do not terminate manager
5114         after unblocking main thread; wait for main thread's
5115         REQ_PROCESS_EXIT request instead.
5116         Also, added REQ_KICK case to handle new request; this just does
5117         nothing.
5118         * manager.c (pthread_exited): Do not terminate manager after
5119         unblocking main thread.
5120         * manager.c (__pthread_manager_sighandler): If the main thread
5121         is waiting for all other threads to die, send a REQ_KICK into
5122         the thread manager request pipe to get it to clean out the threads
5123         and unblock the main thread as soon as possible. This fixes
5124         the 2000 millisecond hang on shutdown bug.
5125         * Examples/ex7.c: New file, tests shutdown behavior when all threads
5126         including the main one call pthread_exit(), or implicitly do so.
5127         * Makefile (tests): Add ex7.
5128
5129 2000-05-05  Andreas Jaeger  <aj@suse.de>

5159
5160         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
5161         now.  First gcc must be fixed (more concrete: libgcc).

5172
5173         * join.c (pthread_exit): Set p_terminated after reporting the
5174         termination event instead of before.

5545         Redesigned how cancellation unblocks a thread from internal
5546         cancellation points (sem_wait, pthread_join,
5547         pthread_cond_{wait,timedwait}).
5548         Cancellation won't eat a signal in any of these functions
5549         (*required* by POSIX and Single Unix Spec!).
5550         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5551         simultaneous condition variable signal (not required by POSIX
5552         or Single Unix Spec, but nice).
5553         * spinlock.c: __pthread_lock queues back any received restarts
5554         that don't belong to it instead of assuming ownership of lock
5555         upon any restart; fastlock can no longer be acquired by two threads
5556         simultaneously.
5557         * restart.h: Restarts queue even on kernels that don't have
5558         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5559         avoiding a rare race condition in pthread_cond_timedwait.
