4329 Bugfixes to the variant of the code for machines with no compare
4332 * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Wait
4333 node was not being properly enqueued, due to failing to update
4334 the lock->__status field.
4336 * spinlock.c (__pthread_alt_timedlock): The oldstatus variable was
4337 being set inappropriately, causing the suspend function to be called
4338 with a null self pointer and crash.

4362 * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Fixed
4363 bug whereby thr field of waitnode structure would not be correctly
4364 set unless a null self pointer is passed to the functions.
4365 Eliminated redundant calls to thread_self().

4601 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4603 Timer nodes are now reference counted, and can be marked
4604 as deleted. This allows for the safe release of the global mutex
4605 in the middle without losing the timer being operated on.
4607 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
4608 member is now an enum with three values, so that an intermediate
4609 state can be represented (deleted but not free for reuse yet).
4610 New refcount member added.

4636 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4637 Returns int value now to indicate whether timer was queued at head.
4638 * sysdeps/pthread/posix-timer.h: Likewise.
4639 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4640 new return value from __timer_thread_queue_timer to avoid waking
4641 up timer thread unnecessarily.
4643 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4644 inuse flag, because this requires mutex to be held. Callers updated
4645 to do the check when they have the mutex.
4646 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4648 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4649 regions: avoids making system calls while holding timer mutex, and
4650 a few computations were moved outside of the mutex as well.
4651 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4653 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4654 to list_unlink_ip, meaning idempotent. Pointer manipulation
4655 changed to get better better code out of gcc.
4656 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4657 version of list_unlink added here.
4658 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4659 function in all places: idempotent one for timers, non-idempotent
4660 one for thread nodes.
4661 * sysdeps/pthread/timer_settime: Likewise.
4662 * sysdeps/pthread/timer_routines.c: Likewise.
4664 2000-06-13 Ulrich Drepper <drepper@redhat.com>
4666 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4694 really append the entry.
4696 2000-06-10 Andreas Jaeger <aj@suse.de>
4698 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
4700 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
4702 * sysdeps/pthread/timer_create.c: Thread matching now done on
4703 clock type as well as thread attributes.
4704 There are individual global signal-delivering threads for
4705 different clock types.
4706 * sysdeps/pthread/posix-timer.h: Likewise.
4707 * sysdeps/pthread/timer_routines.c: Likewise.
4709 * sysdeps/pthread/timer_routines.c: Thread allocation and
4710 deallocation function now remembers to put thread on active
4711 list and remove from active list.
4712 Thus now the feature of binding multiple timers
4713 to a single thread actually works.
4715 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4717 * pthread.c (__pthread_create_2_1): Optimize a bit.
4719 * internals.h (invalid_handle): Also test for p_terminated != 0.

4773 LINK_MAX definitions if necessary.
4775 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
4777 Added missing fork time handling of global libio lock.
4779 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4780 not just the individual stream locks. Rewritten to use new
4781 iterator interface provided by libio rather than accessing
4784 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4785 which lock and unlock the stream list using the new interface
4787 * internals.h: Likewise.
4789 * ptfork.c (__fork): Now calls __flockfilelist before fork,
4790 and __funlockfilelist in the parent after the fork.
4791 Child still calls __fresetlockfiles as before.
4793 * linuxthreads.texi: Now explains what happens to streams at
4794 fork time. Also whole new section on forking and thread added.
4795 Definition of pthread_atfork moved out of Miscellaneous Functions
4796 to this new section.

4823 Bugfix: The pthread_atfork mechanism now takes care of its
4824 own internal mutex at fork time.
4826 * ptfork.c (__fork): Revised so that the mutex is held across
4827 the fork operation and while the handlers are called, and so that
4828 the child resets the mutex.
4830 * linuxthreads.texi: Updated pthread_atfork documentation to make
4831 it clear that fork and pthread_atfork can't be reentered from
4832 atfork handlers, that pthread_atfork and fork are mutually atomic,
4833 and that the handlers are inherited by the child process.

4874 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
4876 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4877 object state is represented with additional bits which distinguish
4878 whether that state was set up in the current process, or
4879 in an ancestor process. If that state was set in an ancestor,
4880 it means that a fork happened while thread was executing the init
4881 function. In that case, the state is reset to NEVER.
4882 * mutex.c (__pthread_once_fork_prepare): New function.
4883 (__pthread_once_fork_child): Likewise

4895 * join.c (pthread_exit): main thread now calls exit() instead
4896 of _exit() in order to proper process cleanup.
4897 * manager.c (__pthread_manager): Do not terminate manager
4898 after unblocking main thread; wait for main thread's
4899 REQ_PROCESS_EXIT request instead.
4900 Also, added REQ_KICK case to handle new request; this just does
4902 * manager.c (pthread_exited): Do not terminate manager after
4903 unblocking main thread.
4904 * manager.c (__pthread_manager_sighandler): If the main thread
4905 is waiting for all other threads to die, send a REQ_KICK into
4906 the thread manager request pipe to get it to clean out the threads
4907 and unblock the main thread as soon as possible. This fixes
4908 the 2000 millisecond hang on shutdown bug.
4909 * Examples/ex7.c: New file, tests shutdown behavior when all threads
4910 including the main one call pthread_exit(), or implicitly do so.
4911 * Makefile (tests): Add ex7.

4993 if fast mutex is used. Don't initialize `already_canceled' twice.
4994 Correctly test for return value of timedsuspend.
4996 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
4997 therefore don't need the _rt versions of the signal handlers.

5329 Redesigned how cancellation unblocks a thread from internal
5330 cancellation points (sem_wait, pthread_join,
5331 pthread_cond_{wait,timedwait}).
5332 Cancellation won't eat a signal in any of these functions
5333 (*required* by POSIX and Single Unix Spec!).
5334 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5335 simultaneous condition variable signal (not required by POSIX
5336 or Single Unix Spec, but nice).
5337 * spinlock.c: __pthread_lock queues back any received restarts
5338 that don't belong to it instead of assuming ownership of lock
5339 upon any restart; fastlock can no longer be acquired by two threads
5341 * restart.h: Restarts queue even on kernels that don't have
5342 queued real time signals (2.0, early 2.1), thanks to atomic counter,
5343 avoiding a rare race condition in pthread_cond_timedwait.
5345 1999-12-31 Andreas Jaeger <aj@suse.de>
5347 * internals.h: Remove duplicate prototype declarations.
5349 * weaks.c: Remove __THROW from prototypes since the file is not
5350 compiled by a C++ compiler.
