4384
4385         Timer nodes are now reference counted, and can be marked

4388
4389         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4390         member is now an enum with three values, so that an intermediate

4422         new return value from __timer_thread_queue_timer to avoid waking
4423         up timer thread unnecessarily.
4424
4425         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4426         inuse flag, because this requires mutex to be held.  Callers updated
4427         to do the check when they have the mutex.
4428         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4429
4430         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4431         regions: avoids making system calls while holding timer mutex, and

4433         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.

4440         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4441         function in all places: idempotent one for timers, non-idempotent
4442         one for thread nodes.
4443         * sysdeps/pthread/timer_settime: Likewise.
4444         * sysdeps/pthread/timer_routines.c: Likewise.

4495         to a single thread actually works.

4560
4561         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4562         not just the individual stream locks. Rewritten to use new
4563         iterator interface provided by libio rather than accessing
4564         global variable.
4565
4566         * lockfile.c (__flockfilelist, _funlockfilelist): New functions

4574
4575         * linuxthreads.texi: Now explains what happens to streams at
4576         fork time. Also whole new section on forking and thread added.

4604
4605         Bugfix: The pthread_atfork mechanism now takes care of its
4606         own internal mutex at fork time.
4607
4608         * ptfork.c (__fork): Revised so that the mutex is held across
4609         the fork operation and while the handlers are called, and so that

4611
4612         * linuxthreads.texi: Updated pthread_atfork documentation to make
4613         it clear that fork and pthread_atfork can't be reentered from

4656 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>

4659         object state is represented with additional bits which distinguish
4660         whether that state was set up in the current process, or
4661         in an ancestor process. If that state was set in an ancestor,
4662         it means that a fork happened while thread was executing the init
4663         function. In that case, the state is reset to NEVER.
4664         * mutex.c (__pthread_once_fork_prepare): New function.

4680         after unblocking main thread; wait for main thread's
4681         REQ_PROCESS_EXIT request instead.
4682         Also, added REQ_KICK case to handle new request; this just does
4683         nothing.
4684         * manager.c (pthread_exited): Do not terminate manager after
4685         unblocking main thread.
4686         * manager.c (__pthread_manager_sighandler): If the main thread

4688         the thread manager request pipe to get it to clean out the threads
4689         and unblock the main thread as soon as possible. This fixes
4690         the 2000 millisecond hang on shutdown bug.
4691         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4692         including the main one call pthread_exit(), or implicitly do so.
4693         * Makefile (tests): Add ex7.
4694
4695 2000-05-05  Andreas Jaeger  <aj@suse.de>

5122         simultaneously.
5123         * restart.h: Restarts queue even on kernels that don't have
5124         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5125         avoiding a rare race condition in pthread_cond_timedwait.

6385         Since sigset_t no longer fits in a register, we can't pass in the

6390         struct instead of as arguments through clone.
