3919 * internals.h: Declare __pthread_max_stacksize.
3920 * pthread.c (__pthread_max_stacksize): New variable.
3921 (__pthread_initialize_manager): Determine __pthread_initialize_manager
3923 * manager.c (thread_segment): Return always NULL if FLOATING_STACKS.
3924 (pthread_allocate_stack): Allow kernel to choose stack address if
3925 FLOATING_STACKS. This also handles variable-sized stacks.

3947 * sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add
3948 load of spin lock to prime the cache before the atomic compare and
3949 exchange operation (cmpxchg4). This avoids the spinning on the
3950 cmpxchg4 instruction and reduces movement of the cache line back
3951 and forth between the processors (explanation by Asis K. Mallick
3952 from Intel). This basically makes the implementation operate the
3953 same as the Linux kernel implementation.

4047 * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Wait
4048 node was not being properly enqueued, due to failing to update
4049 the lock->__status field.
4051 * spinlock.c (__pthread_alt_timedlock): The oldstatus variable was
4052 being set inappropriately, causing the suspend function to be called

4316 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4318 Timer nodes are now reference counted, and can be marked
4319 as deleted. This allows for the safe release of the global mutex
4320 in the middle without losing the timer being operated on.
4322 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
4323 member is now an enum with three values, so that an intermediate
4324 state can be represented (deleted but not free for reuse yet).
4325 New refcount member added.

4338 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4340 2000-06-14 Ulrich Drepper <drepper@redhat.com>

4345 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4347 A few optimizations. Got rid of unnecessary wakeups of timer threads,
4348 tightened up some critical regions and micro-optimized some list
4351 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4352 Returns int value now to indicate whether timer was queued at head.
4353 * sysdeps/pthread/posix-timer.h: Likewise.
4354 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4355 new return value from __timer_thread_queue_timer to avoid waking
4356 up timer thread unnecessarily.
4358 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4359 inuse flag, because this requires mutex to be held. Callers updated
4360 to do the check when they have the mutex.
4361 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4363 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4364 regions: avoids making system calls while holding timer mutex, and
4365 a few computations were moved outside of the mutex as well.
4366 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4368 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4369 to list_unlink_ip, meaning idempotent. Pointer manipulation
4370 changed to get better better code out of gcc.
4371 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4372 version of list_unlink added here.
4373 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink

4422 * sysdeps/pthread/timer_routines.c: Likewise.
4424 * sysdeps/pthread/timer_routines.c: Thread allocation and
4425 deallocation function now remembers to put thread on active
4426 list and remove from active list.
4427 Thus now the feature of binding multiple timers
4428 to a single thread actually works.
4430 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4432 * pthread.c (__pthread_create_2_1): Optimize a bit.
4434 * internals.h (invalid_handle): Also test for p_terminated != 0.

4492 Added missing fork time handling of global libio lock.
4494 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4495 not just the individual stream locks. Rewritten to use new
4496 iterator interface provided by libio rather than accessing
4499 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4500 which lock and unlock the stream list using the new interface
4502 * internals.h: Likewise.
4504 * ptfork.c (__fork): Now calls __flockfilelist before fork,
4505 and __funlockfilelist in the parent after the fork.
4506 Child still calls __fresetlockfiles as before.
4508 * linuxthreads.texi: Now explains what happens to streams at
4509 fork time. Also whole new section on forking and thread added.

4536 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
4538 Bugfix: The pthread_atfork mechanism now takes care of its
4539 own internal mutex at fork time.
4541 * ptfork.c (__fork): Revised so that the mutex is held across
4542 the fork operation and while the handlers are called, and so that
4543 the child resets the mutex.
4545 * linuxthreads.texi: Updated pthread_atfork documentation to make
4546 it clear that fork and pthread_atfork can't be reentered from
4547 atfork handlers, that pthread_atfork and fork are mutually atomic,
4548 and that the handlers are inherited by the child process.
4550 2000-05-24 Ulrich Drepper <drepper@redhat.com>
4552 * Makefile (libpthread-routines): Add pspinlock.
4553 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

4589 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
4591 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4592 object state is represented with additional bits which distinguish
4593 whether that state was set up in the current process, or
4594 in an ancestor process. If that state was set in an ancestor,
4595 it means that a fork happened while thread was executing the init
4596 function. In that case, the state is reset to NEVER.
4597 * mutex.c (__pthread_once_fork_prepare): New function.
4598 (__pthread_once_fork_child): Likewise
4599 (__pthread_once_fork_parent): Likewise

4610 * join.c (pthread_exit): main thread now calls exit() instead
4611 of _exit() in order to proper process cleanup.
4612 * manager.c (__pthread_manager): Do not terminate manager
4613 after unblocking main thread; wait for main thread's
4614 REQ_PROCESS_EXIT request instead.
4615 Also, added REQ_KICK case to handle new request; this just does
4617 * manager.c (pthread_exited): Do not terminate manager after
4618 unblocking main thread.
4619 * manager.c (__pthread_manager_sighandler): If the main thread
4620 is waiting for all other threads to die, send a REQ_KICK into
4621 the thread manager request pipe to get it to clean out the threads
4622 and unblock the main thread as soon as possible. This fixes
4623 the 2000 millisecond hang on shutdown bug.
4624 * Examples/ex7.c: New file, tests shutdown behavior when all threads
4625 including the main one call pthread_exit(), or implicitly do so.
4626 * Makefile (tests): Add ex7.
4628 2000-05-05 Andreas Jaeger <aj@suse.de>

4702 (pthread_getcpuclockid): Don't compare thread_id with thread_self,
4703 use thread_handle().
4705 2000-04-16 Ulrich Drepper <drepper@redhat.com>

4708 if fast mutex is used. Don't initialize `already_canceled' twice.
4709 Correctly test for return value of timedsuspend.
4711 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
4712 therefore don't need the _rt versions of the signal handlers.
4714 2000-04-15 Ulrich Drepper <drepper@redhat.com>

5044 Redesigned how cancellation unblocks a thread from internal
5045 cancellation points (sem_wait, pthread_join,
5046 pthread_cond_{wait,timedwait}).
5047 Cancellation won't eat a signal in any of these functions
5048 (*required* by POSIX and Single Unix Spec!).
5049 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5050 simultaneous condition variable signal (not required by POSIX
5051 or Single Unix Spec, but nice).
5052 * spinlock.c: __pthread_lock queues back any received restarts
5053 that don't belong to it instead of assuming ownership of lock
5054 upon any restart; fastlock can no longer be acquired by two threads
5056 * restart.h: Restarts queue even on kernels that don't have
5057 queued real time signals (2.0, early 2.1), thanks to atomic counter,
5058 avoiding a rare race condition in pthread_cond_timedwait.

5103 new_thread_bottom. Correct handling of stack size and when the
5104 rlimit method to guard for stack growth is used.
5105 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
5106 minus one pagesize (not two).

5192 * pthread.c: For i386, wrap pthread_handle_sigrestart and
