4527 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4529 Timer nodes are now reference counted, and can be marked
4530 as deleted. This allows for the safe release of the global mutex
4531 in the middle without losing the timer being operated on.
4533 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
4534 member is now an enum with three values, so that an intermediate
4535 state can be represented (deleted but not free for reuse yet).
4536 New refcount member added.

4543 restructured, recursive deadlock bug fixed.
4545 * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4546 timer_addref to ensure that timer won't be deleted while mutex is not
4547 held. Also uses timer_invalid to perform validation of timer handle.
4548 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4549 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.

4556 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4558 A few optimizations. Got rid of unnecessary wakeups of timer threads,
4559 tightened up some critical regions and micro-optimized some list
4562 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4563 Returns int value now to indicate whether timer was queued at head.
4564 * sysdeps/pthread/posix-timer.h: Likewise.
4565 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4566 new return value from __timer_thread_queue_timer to avoid waking
4567 up timer thread unnecessarily.
4569 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4570 inuse flag, because this requires mutex to be held. Callers updated
4571 to do the check when they have the mutex.
4572 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4574 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4575 regions: avoids making system calls while holding timer mutex, and
4576 a few computations were moved outside of the mutex as well.
4577 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4579 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4580 to list_unlink_ip, meaning idempotent. Pointer manipulation
4581 changed to get better better code out of gcc.
4582 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4583 version of list_unlink added here.
4584 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4585 function in all places: idempotent one for timers, non-idempotent
4586 one for thread nodes.
4587 * sysdeps/pthread/timer_settime: Likewise.
4588 * sysdeps/pthread/timer_routines.c: Likewise.
4590 2000-06-13 Ulrich Drepper <drepper@redhat.com>
4592 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4620 really append the entry.
4622 2000-06-10 Andreas Jaeger <aj@suse.de>
4624 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
4626 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
4628 * sysdeps/pthread/timer_create.c: Thread matching now done on
4629 clock type as well as thread attributes.
4630 There are individual global signal-delivering threads for
4631 different clock types.
4632 * sysdeps/pthread/posix-timer.h: Likewise.
4633 * sysdeps/pthread/timer_routines.c: Likewise.
4635 * sysdeps/pthread/timer_routines.c: Thread allocation and
4636 deallocation function now remembers to put thread on active
4637 list and remove from active list.
4638 Thus now the feature of binding multiple timers
4639 to a single thread actually works.
4641 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4643 * pthread.c (__pthread_create_2_1): Optimize a bit.
4645 * internals.h (invalid_handle): Also test for p_terminated != 0.
4646 (nonexisting_handle): New function. Same as old invalid_handle.
4647 * join.c (pthread_join): Use nonexisting_handle instead of
4648 invalid_handle to test for acceptable thread handle.
4649 * manager.c (pthread_handle_free): Likewise.
4650 * joinrace.c: New file.
4651 Reported by Permaine Cheung <pcheung@cygnus.com>.

4664 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
4665 CPUTIME clock ID. Add support for thread clocks.
4667 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
4668 subtraction were switched.

4699 LINK_MAX definitions if necessary.
4701 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
4703 Added missing fork time handling of global libio lock.
4705 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4706 not just the individual stream locks. Rewritten to use new
4707 iterator interface provided by libio rather than accessing
4710 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4711 which lock and unlock the stream list using the new interface
4713 * internals.h: Likewise.
4715 * ptfork.c (__fork): Now calls __flockfilelist before fork,
4716 and __funlockfilelist in the parent after the fork.
4717 Child still calls __fresetlockfiles as before.
4719 * linuxthreads.texi: Now explains what happens to streams at
4720 fork time. Also whole new section on forking and thread added.
4721 Definition of pthread_atfork moved out of Miscellaneous Functions
4722 to this new section.
4724 2000-06-04 Jakub Jelinek <jakub@redhat.com>

4745 * Examples/ex8.c: New file.
4747 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
4749 Bugfix: The pthread_atfork mechanism now takes care of its
4750 own internal mutex at fork time.
4752 * ptfork.c (__fork): Revised so that the mutex is held across
4753 the fork operation and while the handlers are called, and so that
4754 the child resets the mutex.
4756 * linuxthreads.texi: Updated pthread_atfork documentation to make
4757 it clear that fork and pthread_atfork can't be reentered from
4758 atfork handlers, that pthread_atfork and fork are mutually atomic,
4759 and that the handlers are inherited by the child process.
4761 2000-05-24 Ulrich Drepper <drepper@redhat.com>
4763 * Makefile (libpthread-routines): Add pspinlock.
4764 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

4802 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4803 object state is represented with additional bits which distinguish
4804 whether that state was set up in the current process, or
4805 in an ancestor process. If that state was set in an ancestor,
4806 it means that a fork happened while thread was executing the init
4807 function. In that case, the state is reset to NEVER.
4808 * mutex.c (__pthread_once_fork_prepare): New function.
4809 (__pthread_once_fork_child): Likewise
4810 (__pthread_once_fork_parent): Likewise
4811 (__pthread_reset_pthread_once): Removed.

4820 * internals.h: New thread manager request type, REQ_KICK.
4821 * join.c (pthread_exit): main thread now calls exit() instead
4822 of _exit() in order to proper process cleanup.
4823 * manager.c (__pthread_manager): Do not terminate manager
4824 after unblocking main thread; wait for main thread's
4825 REQ_PROCESS_EXIT request instead.
4826 Also, added REQ_KICK case to handle new request; this just does
4828 * manager.c (pthread_exited): Do not terminate manager after
4829 unblocking main thread.
4830 * manager.c (__pthread_manager_sighandler): If the main thread
4831 is waiting for all other threads to die, send a REQ_KICK into
4832 the thread manager request pipe to get it to clean out the threads
4833 and unblock the main thread as soon as possible. This fixes
4834 the 2000 millisecond hang on shutdown bug.
4835 * Examples/ex7.c: New file, tests shutdown behavior when all threads
4836 including the main one call pthread_exit(), or implicitly do so.
4837 * Makefile (tests): Add ex7.
4839 2000-05-05 Andreas Jaeger <aj@suse.de>

5255 Redesigned how cancellation unblocks a thread from internal
5256 cancellation points (sem_wait, pthread_join,
5257 pthread_cond_{wait,timedwait}).
5258 Cancellation won't eat a signal in any of these functions
5259 (*required* by POSIX and Single Unix Spec!).
5260 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5261 simultaneous condition variable signal (not required by POSIX
5262 or Single Unix Spec, but nice).
5263 * spinlock.c: __pthread_lock queues back any received restarts
5264 that don't belong to it instead of assuming ownership of lock
5265 upon any restart; fastlock can no longer be acquired by two threads
5267 * restart.h: Restarts queue even on kernels that don't have
5268 queued real time signals (2.0, early 2.1), thanks to atomic counter,
5269 avoiding a rare race condition in pthread_cond_timedwait.

5311 pwrite64, lseek64, open64, and __open64.

5314 new_thread_bottom. Correct handling of stack size and when the
5315 rlimit method to guard for stack growth is used.
5316 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
5317 minus one pagesize (not two).
5319 1999-12-03 Andreas Jaeger <aj@suse.de>
5321 * Versions: Add __res_state with version GLIBC_2.2.

6529 Since sigset_t no longer fits in a register, we can't pass in the
6530 thread's initial mask so easily. Take this opportunity to simplify
6531 the clone implementation by only accepting a single void* argument.
6533 * manager.c (__pthread_manager): Put thread vitals in the thread
6534 struct instead of as arguments through clone.
6535 (pthread_start_thread): Look for them there.
6536 * internals.h (struct _pthread): Add p_initial_fn,
6537 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
6538 * pthread.c (pthread_initialize_manager): Revise clone invocation.
