3097         * sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add
3098         load of spin lock to prime the cache before the atomic compare and

3459         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning
3460         to errno directly.
3461         * sysdeps/pthread/timer_delete.c: Likewise.
3462         * sysdeps/pthread/timer_getoverr.c: Likewise.

3464         * sysdeps/pthread/timer_settime.c: Likewise.
3465
3466 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
3467
3468         Timer nodes are now reference counted, and can be marked
3469         as deleted. This allows for the safe release of the global mutex
3470         in the middle without losing the timer being operated on.
3471
3472         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
3473         member is now an enum with three values, so that an intermediate
3474         state can be represented (deleted but not free for reuse yet).
3475         New refcount member added.
3476         * sysdeps/pthread/timer_routines.c: Likewise.
3477
3478         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
3479         timer_valid): New inline functions added.
3480
3481         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
3482         restructured, recursive deadlock bug fixed.
3483
3484         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
3485         timer_addref to ensure that timer won't be deleted while mutex is not
3486         held. Also uses timer_invalid to perform validation of timer handle.
3487         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
3488         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
3489
3490 2000-06-14  Ulrich Drepper  <drepper@redhat.com>
3491
3492         * shlib-versions: Add entry for SH.
3493         Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
3494
3495 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
3496
3497         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
3498         tightened up some critical regions and micro-optimized some list
3499         manipulation code.
3500
3501         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
3502         Returns int value now to indicate whether timer was queued at head.
3503         * sysdeps/pthread/posix-timer.h: Likewise.
3504         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
3505         new return value from __timer_thread_queue_timer to avoid waking
3506         up timer thread unnecessarily.
3507
3508         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
3509         inuse flag, because this requires mutex to be held.  Callers updated
3510         to do the check when they have the mutex.
3511         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
3512
3513         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
3514         regions: avoids making system calls while holding timer mutex, and
3515         a few computations were moved outside of the mutex as well.
3516         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
3517
3518         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
3519         to list_unlink_ip, meaning idempotent.  Pointer manipulation
3520         changed to get better better code out of gcc.
3521         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
3522         version of list_unlink added here.
3523         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
3524         function in all places: idempotent one for timers, non-idempotent
3525         one for thread nodes.
3526         * sysdeps/pthread/timer_settime: Likewise.
3527         * sysdeps/pthread/timer_routines.c: Likewise.
3528
3529 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
3530
3531         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

3545
3546         * Examples/ex6.c: Test return value of pthread_join.
3547
3548 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
3549
3550         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.

3552         (__pthread_spin_unlock): Implement.
3553         (__pthread_spin_init): Implement.
3554         (__pthread_spin_destroy): Implement.
3555
3556 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
3557
3558         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
3559         really append the entry.

3564
3565 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
3566
3567         * sysdeps/pthread/timer_create.c: Thread matching now done on
3568         clock type as well as thread attributes.
3569         There are individual global signal-delivering threads for
3570         different clock types.
3571         * sysdeps/pthread/posix-timer.h: Likewise.
3572         * sysdeps/pthread/timer_routines.c: Likewise.
3573
3574         * sysdeps/pthread/timer_routines.c: Thread allocation and
3575         deallocation function now remembers to put thread on active
3576         list and remove from active list.
3577         Thus now the feature of binding multiple timers
3578         to a single thread actually works.
3579
3580 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
3581
3582         * pthread.c (__pthread_create_2_1): Optimize a bit.

3585         (nonexisting_handle): New function.  Same as old invalid_handle.
3586         * join.c (pthread_join): Use nonexisting_handle instead of
3587         invalid_handle to test for acceptable thread handle.
3588         * manager.c (pthread_handle_free): Likewise.
3589         * joinrace.c: New file.
3590         Reported by Permaine Cheung <pcheung@cygnus.com>.

3636
3637         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and

3641
3642         Added missing fork time handling of global libio lock.
3643
3644         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
3645         not just the individual stream locks. Rewritten to use new
3646         iterator interface provided by libio rather than accessing
3647         global variable.
3648
3649         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
3650         which lock and unlock the stream list using the new interface
3651         provied by libio.

3653
3654         * ptfork.c (__fork): Now calls __flockfilelist before fork,
3655         and __funlockfilelist in the parent after the fork.
3656         Child still calls __fresetlockfiles as before.
3657
3658         * linuxthreads.texi: Now explains what happens to streams at
3659         fork time. Also whole new section on forking and thread added.
3660         Definition of pthread_atfork moved out of Miscellaneous Functions
3661         to this new section.

3685
3686 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
3687
3688         Bugfix: The pthread_atfork mechanism now takes care of its
3689         own internal mutex at fork time.
3690
3691         * ptfork.c (__fork): Revised so that the mutex is held across
3692         the fork operation and while the handlers are called, and so that
3693         the child resets the mutex.
3694
3695         * linuxthreads.texi: Updated pthread_atfork documentation to make
3696         it clear that fork and pthread_atfork can't be reentered from
3697         atfork handlers, that pthread_atfork and fork are mutually atomic,
3698         and that the handlers are inherited by the child process.
3699
3700 2000-05-24  Ulrich Drepper  <drepper@redhat.com>
3701
3702         * Makefile (libpthread-routines): Add pspinlock.
3703         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

3727 2000-05-24  Andreas Jaeger  <aj@suse.de>
3728
3729         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.

3741         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
3742         object state is represented with additional bits which distinguish
3743         whether that state was set up in the current process, or
3744         in an ancestor process. If that state was set in an ancestor,
3745         it means that a fork happened while thread was executing the init
3746         function. In that case, the state is reset to NEVER.
3747         * mutex.c (__pthread_once_fork_prepare): New function.
3748         (__pthread_once_fork_child): Likewise
3749         (__pthread_once_fork_parent): Likewise
3750         (__pthread_reset_pthread_once): Removed.
3751         * ptfork.c (__fork): Call new handlers in mutex.c.

3756
3757 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
3758
3759         * internals.h: New thread manager request type, REQ_KICK.
3760         * join.c (pthread_exit): main thread now calls exit() instead
3761         of _exit() in order to proper process cleanup.
3762         * manager.c (__pthread_manager): Do not terminate manager
3763         after unblocking main thread; wait for main thread's
3764         REQ_PROCESS_EXIT request instead.
3765         Also, added REQ_KICK case to handle new request; this just does
3766         nothing.
3767         * manager.c (pthread_exited): Do not terminate manager after
3768         unblocking main thread.
3769         * manager.c (__pthread_manager_sighandler): If the main thread
3770         is waiting for all other threads to die, send a REQ_KICK into
3771         the thread manager request pipe to get it to clean out the threads
3772         and unblock the main thread as soon as possible. This fixes
3773         the 2000 millisecond hang on shutdown bug.
3774         * Examples/ex7.c: New file, tests shutdown behavior when all threads
3775         including the main one call pthread_exit(), or implicitly do so.
3776         * Makefile (tests): Add ex7.
3777
3778 2000-05-05  Andreas Jaeger  <aj@suse.de>
3779
3780         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c

4205         simultaneously.
4206         * restart.h: Restarts queue even on kernels that don't have
4207         queued real time signals (2.0, early 2.1), thanks to atomic counter,
