4121         and forth between the processors (explanation by Asis K. Mallick
4122         from Intel). This basically makes the implementation operate the

4486 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4487
4488         Timer nodes are now reference counted, and can be marked
4489         as deleted. This allows for the safe release of the global mutex
4490         in the middle without losing the timer being operated on.
4491
4492         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4493         member is now an enum with three values, so that an intermediate
4494         state can be represented (deleted but not free for reuse yet).
4495         New refcount member added.
4496         * sysdeps/pthread/timer_routines.c: Likewise.
4497
4498         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4499         timer_valid): New inline functions added.
4500
4501         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4502         restructured, recursive deadlock bug fixed.
4503
4504         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4505         timer_addref to ensure that timer won't be deleted while mutex is not
4506         held. Also uses timer_invalid to perform validation of timer handle.
4507         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4508         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4509
4510 2000-06-14  Ulrich Drepper  <drepper@redhat.com>

4513         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4514
4515 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4516
4517         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4518         tightened up some critical regions and micro-optimized some list
4519         manipulation code.
4520
4521         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4522         Returns int value now to indicate whether timer was queued at head.
4523         * sysdeps/pthread/posix-timer.h: Likewise.
4524         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4525         new return value from __timer_thread_queue_timer to avoid waking
4526         up timer thread unnecessarily.
4527
4528         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4529         inuse flag, because this requires mutex to be held.  Callers updated
4530         to do the check when they have the mutex.
4531         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4532
4533         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4534         regions: avoids making system calls while holding timer mutex, and
4535         a few computations were moved outside of the mutex as well.
4536         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4537
4538         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4539         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4540         changed to get better better code out of gcc.
4541         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4542         version of list_unlink added here.
4543         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4544         function in all places: idempotent one for timers, non-idempotent
4545         one for thread nodes.
4546         * sysdeps/pthread/timer_settime: Likewise.
4547         * sysdeps/pthread/timer_routines.c: Likewise.
4548
4549 2000-06-13  Ulrich Drepper  <drepper@redhat.com>

4575
4576 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4577
4578         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4579         really append the entry.

4584
4585 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4586
4587         * sysdeps/pthread/timer_create.c: Thread matching now done on
4588         clock type as well as thread attributes.
4589         There are individual global signal-delivering threads for
4590         different clock types.
4591         * sysdeps/pthread/posix-timer.h: Likewise.
4592         * sysdeps/pthread/timer_routines.c: Likewise.
4593
4594         * sysdeps/pthread/timer_routines.c: Thread allocation and
4595         deallocation function now remembers to put thread on active
4596         list and remove from active list.
4597         Thus now the feature of binding multiple timers
4598         to a single thread actually works.
4599
4600 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4601
4602         * pthread.c (__pthread_create_2_1): Optimize a bit.

4606         * join.c (pthread_join): Use nonexisting_handle instead of
4607         invalid_handle to test for acceptable thread handle.
4608         * manager.c (pthread_handle_free): Likewise.
4609         * joinrace.c: New file.
4610         Reported by Permaine Cheung <pcheung@cygnus.com>.

4656
4657         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

4661
4662         Added missing fork time handling of global libio lock.
4663
4664         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4665         not just the individual stream locks. Rewritten to use new
4666         iterator interface provided by libio rather than accessing
4667         global variable.
4668
4669         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4670         which lock and unlock the stream list using the new interface
4671         provied by libio.

4673
4674         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4675         and __funlockfilelist in the parent after the fork.
4676         Child still calls __fresetlockfiles as before.
4677
4678         * linuxthreads.texi: Now explains what happens to streams at
4679         fork time. Also whole new section on forking and thread added.
4680         Definition of pthread_atfork moved out of Miscellaneous Functions
4681         to this new section.

4705
4706 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4707
4708         Bugfix: The pthread_atfork mechanism now takes care of its
4709         own internal mutex at fork time.
4710
4711         * ptfork.c (__fork): Revised so that the mutex is held across
4712         the fork operation and while the handlers are called, and so that
4713         the child resets the mutex.
4714
4715         * linuxthreads.texi: Updated pthread_atfork documentation to make
4716         it clear that fork and pthread_atfork can't be reentered from
4717         atfork handlers, that pthread_atfork and fork are mutually atomic,
4718         and that the handlers are inherited by the child process.
4719

4747 2000-05-24  Andreas Jaeger  <aj@suse.de>
4748
4749         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.

4761         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4762         object state is represented with additional bits which distinguish
4763         whether that state was set up in the current process, or
4764         in an ancestor process. If that state was set in an ancestor,
4765         it means that a fork happened while thread was executing the init
4766         function. In that case, the state is reset to NEVER.
4767         * mutex.c (__pthread_once_fork_prepare): New function.
4768         (__pthread_once_fork_child): Likewise
4769         (__pthread_once_fork_parent): Likewise
4770         (__pthread_reset_pthread_once): Removed.
4771         * ptfork.c (__fork): Call new handlers in mutex.c.

4778
4779         * internals.h: New thread manager request type, REQ_KICK.
4780         * join.c (pthread_exit): main thread now calls exit() instead
4781         of _exit() in order to proper process cleanup.
4782         * manager.c (__pthread_manager): Do not terminate manager
4783         after unblocking main thread; wait for main thread's
4784         REQ_PROCESS_EXIT request instead.
4785         Also, added REQ_KICK case to handle new request; this just does
4786         nothing.
4787         * manager.c (pthread_exited): Do not terminate manager after
4788         unblocking main thread.
4789         * manager.c (__pthread_manager_sighandler): If the main thread
4790         is waiting for all other threads to die, send a REQ_KICK into
4791         the thread manager request pipe to get it to clean out the threads
4792         and unblock the main thread as soon as possible. This fixes
4793         the 2000 millisecond hang on shutdown bug.
4794         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4795         including the main one call pthread_exit(), or implicitly do so.
4796         * Makefile (tests): Add ex7.
4797
4798 2000-05-05  Andreas Jaeger  <aj@suse.de>
4799
4800         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c

4821         * pthread.c (__pthread_initialize_minimal): New function.  Perform
4822         minimal initialization.

5215         cancellation points (sem_wait, pthread_join,

5223         that don't belong to it instead of assuming ownership of lock

5225         simultaneously.
5226         * restart.h: Restarts queue even on kernels that don't have
5227         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5228         avoiding a rare race condition in pthread_cond_timedwait.
