4442
4443         Timer nodes are now reference counted, and can be marked
4444         as deleted. This allows for the safe release of the global mutex
4445         in the middle without losing the timer being operated on.
4446
4447         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4448         member is now an enum with three values, so that an intermediate

4457         restructured, recursive deadlock bug fixed.
4458
4459         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4460         timer_addref to ensure that timer won't be deleted while mutex is not
4461         held. Also uses timer_invalid to perform validation of timer handle.

4471
4472         A few optimizations.  Got rid of unnecessary wakeups of timer threads,

4479         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4480         new return value from __timer_thread_queue_timer to avoid waking
4481         up timer thread unnecessarily.
4482
4483         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4484         inuse flag, because this requires mutex to be held.  Callers updated
4485         to do the check when they have the mutex.
4486         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4487
4488         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4489         regions: avoids making system calls while holding timer mutex, and
4490         a few computations were moved outside of the mutex as well.
4491         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4492

4501         * sysdeps/pthread/timer_settime: Likewise.
4502         * sysdeps/pthread/timer_routines.c: Likewise.

4541
4542         * sysdeps/pthread/timer_create.c: Thread matching now done on
4543         clock type as well as thread attributes.

4550         deallocation function now remembers to put thread on active
4551         list and remove from active list.
4552         Thus now the feature of binding multiple timers
4553         to a single thread actually works.
4554

4616
4617         Added missing fork time handling of global libio lock.
4618
4619         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4620         not just the individual stream locks. Rewritten to use new
4621         iterator interface provided by libio rather than accessing
4622         global variable.
4623
4624         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4625         which lock and unlock the stream list using the new interface
4626         provied by libio.

4628
4629         * ptfork.c (__fork): Now calls __flockfilelist before fork,
4630         and __funlockfilelist in the parent after the fork.
4631         Child still calls __fresetlockfiles as before.
4632
4633         * linuxthreads.texi: Now explains what happens to streams at
4634         fork time. Also whole new section on forking and thread added.
4635         Definition of pthread_atfork moved out of Miscellaneous Functions
4636         to this new section.

4661 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
4662
4663         Bugfix: The pthread_atfork mechanism now takes care of its
4664         own internal mutex at fork time.
4665
4666         * ptfork.c (__fork): Revised so that the mutex is held across
4667         the fork operation and while the handlers are called, and so that
4668         the child resets the mutex.
4669
4670         * linuxthreads.texi: Updated pthread_atfork documentation to make
4671         it clear that fork and pthread_atfork can't be reentered from
4672         atfork handlers, that pthread_atfork and fork are mutually atomic,
4673         and that the handlers are inherited by the child process.

4714 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>

4716         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4717         object state is represented with additional bits which distinguish
4718         whether that state was set up in the current process, or
4719         in an ancestor process. If that state was set in an ancestor,
4720         it means that a fork happened while thread was executing the init
4721         function. In that case, the state is reset to NEVER.
4722         * mutex.c (__pthread_once_fork_prepare): New function.
4723         (__pthread_once_fork_child): Likewise
4724         (__pthread_once_fork_parent): Likewise
4725         (__pthread_reset_pthread_once): Removed.

4734         * internals.h: New thread manager request type, REQ_KICK.
4735         * join.c (pthread_exit): main thread now calls exit() instead
4736         of _exit() in order to proper process cleanup.
4737         * manager.c (__pthread_manager): Do not terminate manager
4738         after unblocking main thread; wait for main thread's
4739         REQ_PROCESS_EXIT request instead.
4740         Also, added REQ_KICK case to handle new request; this just does
4741         nothing.
4742         * manager.c (pthread_exited): Do not terminate manager after
4743         unblocking main thread.
4744         * manager.c (__pthread_manager_sighandler): If the main thread
4745         is waiting for all other threads to die, send a REQ_KICK into
4746         the thread manager request pipe to get it to clean out the threads
4747         and unblock the main thread as soon as possible. This fixes
4748         the 2000 millisecond hang on shutdown bug.
4749         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4750         including the main one call pthread_exit(), or implicitly do so.
4751         * Makefile (tests): Add ex7.
4752
4753 2000-05-05  Andreas Jaeger  <aj@suse.de>

4783
4784         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
4785         now.  First gcc must be fixed (more concrete: libgcc).

4796
4797         * join.c (pthread_exit): Set p_terminated after reporting the
4798         termination event instead of before.
4799
4800 2000-04-20  Jakub Jelinek  <jakub@redhat.com>
4801
4802         * sysdeps/pthread/bits/libc-lock.h: Only declare __pthread_rwlock_*

4822         headers.

4831
4832         * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
4833         if fast mutex is used.  Don't initialize `already_canceled' twice.
4834         Correctly test for return value of timedsuspend.
4835
4836         * pthread.c: Correct long-time braino.  We never set SA_SIGINFO and

5177         * spinlock.c: __pthread_lock queues back any received restarts
5178         that don't belong to it instead of assuming ownership of lock

5180         simultaneously.
5181         * restart.h: Restarts queue even on kernels that don't have
5182         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5183         avoiding a rare race condition in pthread_cond_timedwait.
