4398
4399         Timer nodes are now reference counted, and can be marked

4402
4403         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4404         member is now an enum with three values, so that an intermediate

4436         new return value from __timer_thread_queue_timer to avoid waking
4437         up timer thread unnecessarily.
4438
4439         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4440         inuse flag, because this requires mutex to be held.  Callers updated
4441         to do the check when they have the mutex.
4442         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4443
4444         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4445         regions: avoids making system calls while holding timer mutex, and

4447         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.

4454         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4455         function in all places: idempotent one for timers, non-idempotent
4456         one for thread nodes.
4457         * sysdeps/pthread/timer_settime: Likewise.
4458         * sysdeps/pthread/timer_routines.c: Likewise.

4508         Thus now the feature of binding multiple timers
4509         to a single thread actually works.

4573         Added missing fork time handling of global libio lock.
4574
4575         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4576         not just the individual stream locks. Rewritten to use new
4577         iterator interface provided by libio rather than accessing
4578         global variable.
4579
4580         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4581         which lock and unlock the stream list using the new interface

4587         Child still calls __fresetlockfiles as before.
4588
4589         * linuxthreads.texi: Now explains what happens to streams at
4590         fork time. Also whole new section on forking and thread added.

4618
4619         Bugfix: The pthread_atfork mechanism now takes care of its
4620         own internal mutex at fork time.
4621
4622         * ptfork.c (__fork): Revised so that the mutex is held across
4623         the fork operation and while the handlers are called, and so that
4624         the child resets the mutex.
4625
4626         * linuxthreads.texi: Updated pthread_atfork documentation to make
4627         it clear that fork and pthread_atfork can't be reentered from

4629         and that the handlers are inherited by the child process.

4670 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>

4673         object state is represented with additional bits which distinguish
4674         whether that state was set up in the current process, or
4675         in an ancestor process. If that state was set in an ancestor,
4676         it means that a fork happened while thread was executing the init
4677         function. In that case, the state is reset to NEVER.
4678         * mutex.c (__pthread_once_fork_prepare): New function.
4679         (__pthread_once_fork_child): Likewise

4691         * join.c (pthread_exit): main thread now calls exit() instead
4692         of _exit() in order to proper process cleanup.
4693         * manager.c (__pthread_manager): Do not terminate manager
4694         after unblocking main thread; wait for main thread's
4695         REQ_PROCESS_EXIT request instead.
4696         Also, added REQ_KICK case to handle new request; this just does
4697         nothing.
4698         * manager.c (pthread_exited): Do not terminate manager after
4699         unblocking main thread.
4700         * manager.c (__pthread_manager_sighandler): If the main thread
4701         is waiting for all other threads to die, send a REQ_KICK into
4702         the thread manager request pipe to get it to clean out the threads
4703         and unblock the main thread as soon as possible. This fixes
4704         the 2000 millisecond hang on shutdown bug.
4705         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4706         including the main one call pthread_exit(), or implicitly do so.
4707         * Makefile (tests): Add ex7.
4708
4709 2000-05-05  Andreas Jaeger  <aj@suse.de>

4739
4740         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for

5136         simultaneously.
5137         * restart.h: Restarts queue even on kernels that don't have
5138         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5139         avoiding a rare race condition in pthread_cond_timedwait.

6399         Since sigset_t no longer fits in a register, we can't pass in the

6404         struct instead of as arguments through clone.
