4494
4495         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4496         restructured, recursive deadlock bug fixed.
4497
4498         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4499         timer_addref to ensure that timer won't be deleted while mutex is not
4500         held. Also uses timer_invalid to perform validation of timer handle.
4501         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4502         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.

4509 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
4510
4511         A few optimizations.  Got rid of unnecessary wakeups of timer threads,

4513         manipulation code.
4514
4515         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):

4517         * sysdeps/pthread/posix-timer.h: Likewise.
4518         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4519         new return value from __timer_thread_queue_timer to avoid waking
4520         up timer thread unnecessarily.
4521
4522         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4523         inuse flag, because this requires mutex to be held.  Callers updated
4524         to do the check when they have the mutex.
4525         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4526
4527         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4528         regions: avoids making system calls while holding timer mutex, and
4529         a few computations were moved outside of the mutex as well.
4530         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4531
4532         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed

4534         changed to get better better code out of gcc.
4535         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4536         version of list_unlink added here.
4537         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4538         function in all places: idempotent one for timers, non-idempotent
4539         one for thread nodes.
4540         * sysdeps/pthread/timer_settime: Likewise.
4541         * sysdeps/pthread/timer_routines.c: Likewise.

4580
4581         * sysdeps/pthread/timer_create.c: Thread matching now done on
4582         clock type as well as thread attributes.
4583         There are individual global signal-delivering threads for
4584         different clock types.
4585         * sysdeps/pthread/posix-timer.h: Likewise.
4586         * sysdeps/pthread/timer_routines.c: Likewise.
4587
4588         * sysdeps/pthread/timer_routines.c: Thread allocation and
4589         deallocation function now remembers to put thread on active
4590         list and remove from active list.
4591         Thus now the feature of binding multiple timers
4592         to a single thread actually works.
4593

4656         Added missing fork time handling of global libio lock.
4657
4658         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4659         not just the individual stream locks. Rewritten to use new
4660         iterator interface provided by libio rather than accessing
4661         global variable.
4662
4663         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4664         which lock and unlock the stream list using the new interface
4665         provied by libio.

4667
4668         * ptfork.c (__fork): Now calls __flockfilelist before fork,

4670         Child still calls __fresetlockfiles as before.
4671
4672         * linuxthreads.texi: Now explains what happens to streams at
4673         fork time. Also whole new section on forking and thread added.
4674         Definition of pthread_atfork moved out of Miscellaneous Functions

4700 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4701
4702         Bugfix: The pthread_atfork mechanism now takes care of its
4703         own internal mutex at fork time.
4704
4705         * ptfork.c (__fork): Revised so that the mutex is held across
4706         the fork operation and while the handlers are called, and so that
4707         the child resets the mutex.
4708
4709         * linuxthreads.texi: Updated pthread_atfork documentation to make
4710         it clear that fork and pthread_atfork can't be reentered from
4711         atfork handlers, that pthread_atfork and fork are mutually atomic,
4712         and that the handlers are inherited by the child process.

4756         object state is represented with additional bits which distinguish
4757         whether that state was set up in the current process, or
4758         in an ancestor process. If that state was set in an ancestor,
4759         it means that a fork happened while thread was executing the init
4760         function. In that case, the state is reset to NEVER.
4761         * mutex.c (__pthread_once_fork_prepare): New function.
4762         (__pthread_once_fork_child): Likewise
4763         (__pthread_once_fork_parent): Likewise

4772
4773         * internals.h: New thread manager request type, REQ_KICK.
4774         * join.c (pthread_exit): main thread now calls exit() instead
4775         of _exit() in order to proper process cleanup.
4776         * manager.c (__pthread_manager): Do not terminate manager
4777         after unblocking main thread; wait for main thread's
4778         REQ_PROCESS_EXIT request instead.
4779         Also, added REQ_KICK case to handle new request; this just does
4780         nothing.
4781         * manager.c (pthread_exited): Do not terminate manager after
4782         unblocking main thread.
4783         * manager.c (__pthread_manager_sighandler): If the main thread
4784         is waiting for all other threads to die, send a REQ_KICK into
4785         the thread manager request pipe to get it to clean out the threads
4786         and unblock the main thread as soon as possible. This fixes
4787         the 2000 millisecond hang on shutdown bug.
4788         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4789         including the main one call pthread_exit(), or implicitly do so.
4790         * Makefile (tests): Add ex7.
4791
4792 2000-05-05  Andreas Jaeger  <aj@suse.de>

5209         cancellation points (sem_wait, pthread_join,
5210         pthread_cond_{wait,timedwait}).
5211         Cancellation won't eat a signal in any of these functions
5212         (*required* by POSIX and Single Unix Spec!).
5213         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a

5216         * spinlock.c: __pthread_lock queues back any received restarts
5217         that don't belong to it instead of assuming ownership of lock
5218         upon any restart; fastlock can no longer be acquired by two threads
5219         simultaneously.
5220         * restart.h: Restarts queue even on kernels that don't have
5221         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5222         avoiding a rare race condition in pthread_cond_timedwait.
