4424
4425         Timer nodes are now reference counted, and can be marked
4426         as deleted. This allows for the safe release of the global mutex
4427         in the middle without losing the timer being operated on.
4428
4429         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4430         member is now an enum with three values, so that an intermediate
4431         state can be represented (deleted but not free for reuse yet).

4439         restructured, recursive deadlock bug fixed.
4440
4441         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4442         timer_addref to ensure that timer won't be deleted while mutex is not
4443         held. Also uses timer_invalid to perform validation of timer handle.

4462         new return value from __timer_thread_queue_timer to avoid waking
4463         up timer thread unnecessarily.
4464
4465         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4466         inuse flag, because this requires mutex to be held.  Callers updated
4467         to do the check when they have the mutex.
4468         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4469
4470         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4471         regions: avoids making system calls while holding timer mutex, and
4472         a few computations were moved outside of the mutex as well.
4473         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4474
4475         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed

4479         version of list_unlink added here.
4480         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4481         function in all places: idempotent one for timers, non-idempotent
4482         one for thread nodes.
4483         * sysdeps/pthread/timer_settime: Likewise.
4484         * sysdeps/pthread/timer_routines.c: Likewise.

4535         to a single thread actually works.
4536

4599         Added missing fork time handling of global libio lock.
4600
4601         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4602         not just the individual stream locks. Rewritten to use new
4603         iterator interface provided by libio rather than accessing
4604         global variable.
4605
4606         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4607         which lock and unlock the stream list using the new interface
4608         provied by libio.

4610
4611         * ptfork.c (__fork): Now calls __flockfilelist before fork,

4613         Child still calls __fresetlockfiles as before.
4614
4615         * linuxthreads.texi: Now explains what happens to streams at
4616         fork time. Also whole new section on forking and thread added.

4644
4645         Bugfix: The pthread_atfork mechanism now takes care of its
4646         own internal mutex at fork time.
4647
4648         * ptfork.c (__fork): Revised so that the mutex is held across
4649         the fork operation and while the handlers are called, and so that
4650         the child resets the mutex.
4651
4652         * linuxthreads.texi: Updated pthread_atfork documentation to make
4653         it clear that fork and pthread_atfork can't be reentered from

4694         * internals.h (__RES_PTHREAD_INTERNAL): Define.
4695
4696 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>

4699         object state is represented with additional bits which distinguish
4700         whether that state was set up in the current process, or
4701         in an ancestor process. If that state was set in an ancestor,
4702         it means that a fork happened while thread was executing the init
4703         function. In that case, the state is reset to NEVER.
4704         * mutex.c (__pthread_once_fork_prepare): New function.

4717         * join.c (pthread_exit): main thread now calls exit() instead
4718         of _exit() in order to proper process cleanup.
4719         * manager.c (__pthread_manager): Do not terminate manager
4720         after unblocking main thread; wait for main thread's
4721         REQ_PROCESS_EXIT request instead.
4722         Also, added REQ_KICK case to handle new request; this just does
4723         nothing.
4724         * manager.c (pthread_exited): Do not terminate manager after
4725         unblocking main thread.
4726         * manager.c (__pthread_manager_sighandler): If the main thread
4727         is waiting for all other threads to die, send a REQ_KICK into
4728         the thread manager request pipe to get it to clean out the threads
4729         and unblock the main thread as soon as possible. This fixes
4730         the 2000 millisecond hang on shutdown bug.
4731         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4732         including the main one call pthread_exit(), or implicitly do so.
4733         * Makefile (tests): Add ex7.
4734
4735 2000-05-05  Andreas Jaeger  <aj@suse.de>

4765
4766         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for

5162         simultaneously.
5163         * restart.h: Restarts queue even on kernels that don't have
5164         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5165         avoiding a rare race condition in pthread_cond_timedwait.
