4346
4347         Timer nodes are now reference counted, and can be marked
4348         as deleted. This allows for the safe release of the global mutex
4349         in the middle without losing the timer being operated on.
4350
4351         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4352         member is now an enum with three values, so that an intermediate

4361         restructured, recursive deadlock bug fixed.
4362
4363         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4364         timer_addref to ensure that timer won't be deleted while mutex is not
4365         held. Also uses timer_invalid to perform validation of timer handle.
4366         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4367         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.

4384         new return value from __timer_thread_queue_timer to avoid waking
4385         up timer thread unnecessarily.
4386
4387         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4388         inuse flag, because this requires mutex to be held.  Callers updated
4389         to do the check when they have the mutex.
4390         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4391
4392         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4393         regions: avoids making system calls while holding timer mutex, and
4394         a few computations were moved outside of the mutex as well.
4395         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4396
4397         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4398         to list_unlink_ip, meaning idempotent.  Pointer manipulation

4401         version of list_unlink added here.
4402         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4403         function in all places: idempotent one for timers, non-idempotent
4404         one for thread nodes.
4405         * sysdeps/pthread/timer_settime: Likewise.
4406         * sysdeps/pthread/timer_routines.c: Likewise.

4445
4446         * sysdeps/pthread/timer_create.c: Thread matching now done on
4447         clock type as well as thread attributes.
4448         There are individual global signal-delivering threads for
4449         different clock types.
4450         * sysdeps/pthread/posix-timer.h: Likewise.
4451         * sysdeps/pthread/timer_routines.c: Likewise.
4452
4453         * sysdeps/pthread/timer_routines.c: Thread allocation and
4454         deallocation function now remembers to put thread on active
4455         list and remove from active list.
4456         Thus now the feature of binding multiple timers
4457         to a single thread actually works.
4458

4522
4523         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4524         not just the individual stream locks. Rewritten to use new
4525         iterator interface provided by libio rather than accessing
4526         global variable.
4527
4528         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4529         which lock and unlock the stream list using the new interface

4532

4535         Child still calls __fresetlockfiles as before.
4536
4537         * linuxthreads.texi: Now explains what happens to streams at
4538         fork time. Also whole new section on forking and thread added.
4539         Definition of pthread_atfork moved out of Miscellaneous Functions

4566
4567         Bugfix: The pthread_atfork mechanism now takes care of its
4568         own internal mutex at fork time.
4569
4570         * ptfork.c (__fork): Revised so that the mutex is held across
4571         the fork operation and while the handlers are called, and so that
4572         the child resets the mutex.
4573
4574         * linuxthreads.texi: Updated pthread_atfork documentation to make
4575         it clear that fork and pthread_atfork can't be reentered from

4577         and that the handlers are inherited by the child process.

4618 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>

4621         object state is represented with additional bits which distinguish
4622         whether that state was set up in the current process, or
4623         in an ancestor process. If that state was set in an ancestor,
4624         it means that a fork happened while thread was executing the init
4625         function. In that case, the state is reset to NEVER.
4626         * mutex.c (__pthread_once_fork_prepare): New function.

4642         after unblocking main thread; wait for main thread's
4643         REQ_PROCESS_EXIT request instead.
4644         Also, added REQ_KICK case to handle new request; this just does
4645         nothing.
4646         * manager.c (pthread_exited): Do not terminate manager after
4647         unblocking main thread.
4648         * manager.c (__pthread_manager_sighandler): If the main thread

4650         the thread manager request pipe to get it to clean out the threads
4651         and unblock the main thread as soon as possible. This fixes
4652         the 2000 millisecond hang on shutdown bug.
4653         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4654         including the main one call pthread_exit(), or implicitly do so.
4655         * Makefile (tests): Add ex7.
4656
4657 2000-05-05  Andreas Jaeger  <aj@suse.de>

6347         Since sigset_t no longer fits in a register, we can't pass in the
6348         thread's initial mask so easily.  Take this opportunity to simplify

6350
6351         * manager.c (__pthread_manager): Put thread vitals in the thread
6352         struct instead of as arguments through clone.

6354         * internals.h (struct _pthread): Add p_initial_fn,
6355         p_initial_fn_arg, p_initial_mask.  Fix __pthread_manager proto.
6356         * pthread.c (pthread_initialize_manager): Revise clone invocation.
