4126         cmpxchg4 instruction and reduces movement of the cache line back
4127         and forth between the processors (explanation by Asis K. Mallick
4128         from Intel). This basically makes the implementation operate the

4492 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4493
4494         Timer nodes are now reference counted, and can be marked
4495         as deleted. This allows for the safe release of the global mutex
4496         in the middle without losing the timer being operated on.
4497
4498         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4499         member is now an enum with three values, so that an intermediate
4500         state can be represented (deleted but not free for reuse yet).
4501         New refcount member added.
4502         * sysdeps/pthread/timer_routines.c: Likewise.
4503
4504         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4505         timer_valid): New inline functions added.
4506
4507         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4508         restructured, recursive deadlock bug fixed.
4509
4510         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4511         timer_addref to ensure that timer won't be deleted while mutex is not
4512         held. Also uses timer_invalid to perform validation of timer handle.
4513         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4514         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4515
4516 2000-06-14  Ulrich Drepper  <drepper@redhat.com>

4519         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4520
4521 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4522
4523         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4524         tightened up some critical regions and micro-optimized some list
4525         manipulation code.
4526
4527         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4528         Returns int value now to indicate whether timer was queued at head.
4529         * sysdeps/pthread/posix-timer.h: Likewise.
4530         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4531         new return value from __timer_thread_queue_timer to avoid waking
4532         up timer thread unnecessarily.
4533
4534         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4535         inuse flag, because this requires mutex to be held.  Callers updated
4536         to do the check when they have the mutex.
4537         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4538
4539         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4540         regions: avoids making system calls while holding timer mutex, and
4541         a few computations were moved outside of the mutex as well.
4542         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4543
4544         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4545         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4546         changed to get better better code out of gcc.
4547         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4548         version of list_unlink added here.
4549         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4550         function in all places: idempotent one for timers, non-idempotent
4551         one for thread nodes.
4552         * sysdeps/pthread/timer_settime: Likewise.
4553         * sysdeps/pthread/timer_routines.c: Likewise.
4554
4555 2000-06-13  Ulrich Drepper  <drepper@redhat.com>

4581
4582 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4583
4584         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4585         really append the entry.

4590
4591 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4592
4593         * sysdeps/pthread/timer_create.c: Thread matching now done on
4594         clock type as well as thread attributes.
4595         There are individual global signal-delivering threads for
4596         different clock types.
4597         * sysdeps/pthread/posix-timer.h: Likewise.
4598         * sysdeps/pthread/timer_routines.c: Likewise.
4599
4600         * sysdeps/pthread/timer_routines.c: Thread allocation and
4601         deallocation function now remembers to put thread on active
4602         list and remove from active list.
4603         Thus now the feature of binding multiple timers
4604         to a single thread actually works.
4605
4606 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4607
4608         * pthread.c (__pthread_create_2_1): Optimize a bit.

4610         * internals.h (invalid_handle): Also test for p_terminated != 0.
4611         (nonexisting_handle): New function.  Same as old invalid_handle.
4612         * join.c (pthread_join): Use nonexisting_handle instead of
4613         invalid_handle to test for acceptable thread handle.
4614         * manager.c (pthread_handle_free): Likewise.
4615         * joinrace.c: New file.
4616         Reported by Permaine Cheung <pcheung@cygnus.com>.

4662
4663         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4667
4668         Added missing fork time handling of global libio lock.
4669
4670         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4671         not just the individual stream locks. Rewritten to use new
4672         iterator interface provided by libio rather than accessing
4673         global variable.
4674
4675         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4676         which lock and unlock the stream list using the new interface
4677         provied by libio.

4679
4680         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4681         and __funlockfilelist in the parent after the fork.
4682         Child still calls __fresetlockfiles as before.
4683
4684         * linuxthreads.texi: Now explains what happens to streams at
4685         fork time. Also whole new section on forking and thread added.
4686         Definition of pthread_atfork moved out of Miscellaneous Functions
4687         to this new section.

4711
4712 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4713
4714         Bugfix: The pthread_atfork mechanism now takes care of its
4715         own internal mutex at fork time.
4716
4717         * ptfork.c (__fork): Revised so that the mutex is held across
4718         the fork operation and while the handlers are called, and so that
4719         the child resets the mutex.
4720
4721         * linuxthreads.texi: Updated pthread_atfork documentation to make
4722         it clear that fork and pthread_atfork can't be reentered from
4723         atfork handlers, that pthread_atfork and fork are mutually atomic,
4724         and that the handlers are inherited by the child process.
4725

4753 2000-05-24  Andreas Jaeger  <aj@suse.de>
4754
4755         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.

4767         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4768         object state is represented with additional bits which distinguish
4769         whether that state was set up in the current process, or
4770         in an ancestor process. If that state was set in an ancestor,
4771         it means that a fork happened while thread was executing the init
4772         function. In that case, the state is reset to NEVER.
4773         * mutex.c (__pthread_once_fork_prepare): New function.
4774         (__pthread_once_fork_child): Likewise
4775         (__pthread_once_fork_parent): Likewise
4776         (__pthread_reset_pthread_once): Removed.
4777         * ptfork.c (__fork): Call new handlers in mutex.c.

4784
4785         * internals.h: New thread manager request type, REQ_KICK.
4786         * join.c (pthread_exit): main thread now calls exit() instead
4787         of _exit() in order to proper process cleanup.
4788         * manager.c (__pthread_manager): Do not terminate manager
4789         after unblocking main thread; wait for main thread's
4790         REQ_PROCESS_EXIT request instead.
4791         Also, added REQ_KICK case to handle new request; this just does
4792         nothing.
4793         * manager.c (pthread_exited): Do not terminate manager after
4794         unblocking main thread.
4795         * manager.c (__pthread_manager_sighandler): If the main thread
4796         is waiting for all other threads to die, send a REQ_KICK into
4797         the thread manager request pipe to get it to clean out the threads
4798         and unblock the main thread as soon as possible. This fixes
4799         the 2000 millisecond hang on shutdown bug.
4800         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4801         including the main one call pthread_exit(), or implicitly do so.
4802         * Makefile (tests): Add ex7.
4803
4804 2000-05-05  Andreas Jaeger  <aj@suse.de>
4805
4806         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c

4827         * pthread.c (__pthread_initialize_minimal): New function.  Perform
4828         minimal initialization.

5221         cancellation points (sem_wait, pthread_join,

5229         that don't belong to it instead of assuming ownership of lock

5231         simultaneously.
5232         * restart.h: Restarts queue even on kernels that don't have
5233         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5234         avoiding a rare race condition in pthread_cond_timedwait.
