4487
4488         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
4489         tightened up some critical regions and micro-optimized some list
4490         manipulation code.
4491
4492         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4493         Returns int value now to indicate whether timer was queued at head.
4494         * sysdeps/pthread/posix-timer.h: Likewise.
4495         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4496         new return value from __timer_thread_queue_timer to avoid waking
4497         up timer thread unnecessarily.
4498
4499         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4500         inuse flag, because this requires mutex to be held.  Callers updated
4501         to do the check when they have the mutex.
4502         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4503
4504         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4505         regions: avoids making system calls while holding timer mutex, and
4506         a few computations were moved outside of the mutex as well.
4507         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4508
4509         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4510         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4511         changed to get better better code out of gcc.
4512         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4513         version of list_unlink added here.
4514         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4515         function in all places: idempotent one for timers, non-idempotent
4516         one for thread nodes.
4517         * sysdeps/pthread/timer_settime: Likewise.
4518         * sysdeps/pthread/timer_routines.c: Likewise.
4519
4520 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
4521
4522         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
4523         * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.
4524
4525         * sysdeps/pthread/Makefile: Remove tests definition.
4526
4527 2000-06-12  Kazumoto Kojima  <kkojima@rr.iij4u.or.jp>
4528             Yutaka Niibe  <gniibe@chroot.org>
4529

4534
4535         * Makefile (tests): Add joinrace.
4536
4537         * Examples/ex6.c: Test return value of pthread_join.
4538
4539 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4540
4541         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4542         (__pthread_spin_trylock): Implement.
4543         (__pthread_spin_unlock): Implement.
4544         (__pthread_spin_init): Implement.
4545         (__pthread_spin_destroy): Implement.
4546
4547 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4548
4549         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4550         really append the entry.
4551

4555
4556 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4557
4558         * sysdeps/pthread/timer_create.c: Thread matching now done on
4559         clock type as well as thread attributes.
4560         There are individual global signal-delivering threads for
4561         different clock types.
4562         * sysdeps/pthread/posix-timer.h: Likewise.
4563         * sysdeps/pthread/timer_routines.c: Likewise.
4564
4565         * sysdeps/pthread/timer_routines.c: Thread allocation and
4566         deallocation function now remembers to put thread on active
4567         list and remove from active list.
4568         Thus now the feature of binding multiple timers
4569         to a single thread actually works.
4570
4571 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4572
4573         * pthread.c (__pthread_create_2_1): Optimize a bit.
4574
4575         * internals.h (invalid_handle): Also test for p_terminated != 0.

4577         * join.c (pthread_join): Use nonexisting_handle instead of
4578         invalid_handle to test for acceptable thread handle.
4579         * manager.c (pthread_handle_free): Likewise.
4580         * joinrace.c: New file.
4581         Reported by Permaine Cheung <pcheung@cygnus.com>.
4582

4598         subtraction were switched.

4625
4626 2000-06-08  Ulrich Drepper  <drepper@redhat.com>
4627
4628         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and
4629         LINK_MAX definitions if necessary.

4632
4633         Added missing fork time handling of global libio lock.
4634
4635         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4636         not just the individual stream locks. Rewritten to use new
4637         iterator interface provided by libio rather than accessing
4638         global variable.
4639
4640         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4641         which lock and unlock the stream list using the new interface
4642         provied by libio.

4644
4645         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4646         and __funlockfilelist in the parent after the fork.
4647         Child still calls __fresetlockfiles as before.
4648
4649         * linuxthreads.texi: Now explains what happens to streams at
4650         fork time. Also whole new section on forking and thread added.
4651         Definition of pthread_atfork moved out of Miscellaneous Functions
4652         to this new section.

4676
4677 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4678
4679         Bugfix: The pthread_atfork mechanism now takes care of its
4680         own internal mutex at fork time.
4681
4682         * ptfork.c (__fork): Revised so that the mutex is held across
4683         the fork operation and while the handlers are called, and so that
4684         the child resets the mutex.
4685
4686         * linuxthreads.texi: Updated pthread_atfork documentation to make
4687         it clear that fork and pthread_atfork can't be reentered from
4688         atfork handlers, that pthread_atfork and fork are mutually atomic,
4689         and that the handlers are inherited by the child process.

4729
4730 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4731
4732         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4733         object state is represented with additional bits which distinguish
4734         whether that state was set up in the current process, or
4735         in an ancestor process. If that state was set in an ancestor,
4736         it means that a fork happened while thread was executing the init
4737         function. In that case, the state is reset to NEVER.
4738         * mutex.c (__pthread_once_fork_prepare): New function.
4739         (__pthread_once_fork_child): Likewise
4740         (__pthread_once_fork_parent): Likewise
4741         (__pthread_reset_pthread_once): Removed.
4742         * ptfork.c (__fork): Call new handlers in mutex.c.

4746         to clarify what happens under cancellation and forking.
4747
4748 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
4749
4750         * internals.h: New thread manager request type, REQ_KICK.
4751         * join.c (pthread_exit): main thread now calls exit() instead
4752         of _exit() in order to proper process cleanup.
4753         * manager.c (__pthread_manager): Do not terminate manager
4754         after unblocking main thread; wait for main thread's
4755         REQ_PROCESS_EXIT request instead.
4756         Also, added REQ_KICK case to handle new request; this just does
4757         nothing.
4758         * manager.c (pthread_exited): Do not terminate manager after
4759         unblocking main thread.
4760         * manager.c (__pthread_manager_sighandler): If the main thread
4761         is waiting for all other threads to die, send a REQ_KICK into
4762         the thread manager request pipe to get it to clean out the threads
4763         and unblock the main thread as soon as possible. This fixes
4764         the 2000 millisecond hang on shutdown bug.
4765         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4766         including the main one call pthread_exit(), or implicitly do so.
4767         * Makefile (tests): Add ex7.
4768
4769 2000-05-05  Andreas Jaeger  <aj@suse.de>
4770
4771         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c

4799
4800         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
4801         now.  First gcc must be fixed (more concrete: libgcc).

4812
4813         * join.c (pthread_exit): Set p_terminated after reporting the
4814         termination event instead of before.
4815

5196         simultaneously.
5197         * restart.h: Restarts queue even on kernels that don't have
5198         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5199         avoiding a rare race condition in pthread_cond_timedwait.
