4432
4433         Timer nodes are now reference counted, and can be marked
4434         as deleted. This allows for the safe release of the global mutex
4435         in the middle without losing the timer being operated on.
4436
4437         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4438         member is now an enum with three values, so that an intermediate
4439         state can be represented (deleted but not free for reuse yet).
4440         New refcount member added.
4441         * sysdeps/pthread/timer_routines.c: Likewise.

4447         restructured, recursive deadlock bug fixed.
4448
4449         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4450         timer_addref to ensure that timer won't be deleted while mutex is not
4451         held. Also uses timer_invalid to perform validation of timer handle.
4452         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4453         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.

4461
4462         A few optimizations.  Got rid of unnecessary wakeups of timer threads,

4469         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4470         new return value from __timer_thread_queue_timer to avoid waking
4471         up timer thread unnecessarily.
4472
4473         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4474         inuse flag, because this requires mutex to be held.  Callers updated
4475         to do the check when they have the mutex.
4476         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4477
4478         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4479         regions: avoids making system calls while holding timer mutex, and
4480         a few computations were moved outside of the mutex as well.
4481         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4482
4483         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4484         to list_unlink_ip, meaning idempotent.  Pointer manipulation

4608
4609         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4610         not just the individual stream locks. Rewritten to use new
4611         iterator interface provided by libio rather than accessing
4612         global variable.
4613
4614         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4615         which lock and unlock the stream list using the new interface

4621         Child still calls __fresetlockfiles as before.
4622
4623         * linuxthreads.texi: Now explains what happens to streams at
4624         fork time. Also whole new section on forking and thread added.

4652
4653         Bugfix: The pthread_atfork mechanism now takes care of its
4654         own internal mutex at fork time.
4655
4656         * ptfork.c (__fork): Revised so that the mutex is held across
4657         the fork operation and while the handlers are called, and so that
4658         the child resets the mutex.
4659
4660         * linuxthreads.texi: Updated pthread_atfork documentation to make
4661         it clear that fork and pthread_atfork can't be reentered from

4704 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>

4707         object state is represented with additional bits which distinguish
4708         whether that state was set up in the current process, or
4709         in an ancestor process. If that state was set in an ancestor,
4710         it means that a fork happened while thread was executing the init
4711         function. In that case, the state is reset to NEVER.
4712         * mutex.c (__pthread_once_fork_prepare): New function.
4713         (__pthread_once_fork_child): Likewise

4725         * join.c (pthread_exit): main thread now calls exit() instead
4726         of _exit() in order to proper process cleanup.

4728         after unblocking main thread; wait for main thread's
4729         REQ_PROCESS_EXIT request instead.
4730         Also, added REQ_KICK case to handle new request; this just does
4731         nothing.
4732         * manager.c (pthread_exited): Do not terminate manager after
4733         unblocking main thread.
4734         * manager.c (__pthread_manager_sighandler): If the main thread
4735         is waiting for all other threads to die, send a REQ_KICK into
4736         the thread manager request pipe to get it to clean out the threads
4737         and unblock the main thread as soon as possible. This fixes
4738         the 2000 millisecond hang on shutdown bug.
4739         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4740         including the main one call pthread_exit(), or implicitly do so.
4741         * Makefile (tests): Add ex7.
4742
4743 2000-05-05  Andreas Jaeger  <aj@suse.de>

4774         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for

5170         simultaneously.
5171         * restart.h: Restarts queue even on kernels that don't have
5172         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5173         avoiding a rare race condition in pthread_cond_timedwait.
