4492 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4494 Timer nodes are now reference counted, and can be marked
4495 as deleted. This allows for the safe release of the global mutex
4496 in the middle without losing the timer being operated on.
4498 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
4499 member is now an enum with three values, so that an intermediate
4500 state can be represented (deleted but not free for reuse yet).
4501 New refcount member added.

4508 restructured, recursive deadlock bug fixed.
4510 * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4511 timer_addref to ensure that timer won't be deleted while mutex is not
4512 held. Also uses timer_invalid to perform validation of timer handle.
4513 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4514 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4516 2000-06-14 Ulrich Drepper <drepper@redhat.com>

4519 Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4521 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4523 A few optimizations. Got rid of unnecessary wakeups of timer threads,
4524 tightened up some critical regions and micro-optimized some list
4527 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4528 Returns int value now to indicate whether timer was queued at head.
4529 * sysdeps/pthread/posix-timer.h: Likewise.
4530 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4531 new return value from __timer_thread_queue_timer to avoid waking
4532 up timer thread unnecessarily.
4534 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4535 inuse flag, because this requires mutex to be held. Callers updated
4536 to do the check when they have the mutex.
4537 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4539 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4540 regions: avoids making system calls while holding timer mutex, and
4541 a few computations were moved outside of the mutex as well.
4542 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4544 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4545 to list_unlink_ip, meaning idempotent. Pointer manipulation
4546 changed to get better better code out of gcc.
4547 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4548 version of list_unlink added here.
4549 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4550 function in all places: idempotent one for timers, non-idempotent
4551 one for thread nodes.
4552 * sysdeps/pthread/timer_settime: Likewise.
4553 * sysdeps/pthread/timer_routines.c: Likewise.
4555 2000-06-13 Ulrich Drepper <drepper@redhat.com>
4557 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

4579 (__pthread_spin_init): Implement.
4580 (__pthread_spin_destroy): Implement.
4582 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4584 * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4585 really append the entry.
4587 2000-06-10 Andreas Jaeger <aj@suse.de>
4589 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
4591 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
4593 * sysdeps/pthread/timer_create.c: Thread matching now done on
4594 clock type as well as thread attributes.
4595 There are individual global signal-delivering threads for
4596 different clock types.
4597 * sysdeps/pthread/posix-timer.h: Likewise.
4598 * sysdeps/pthread/timer_routines.c: Likewise.
4600 * sysdeps/pthread/timer_routines.c: Thread allocation and
4601 deallocation function now remembers to put thread on active
4602 list and remove from active list.
4603 Thus now the feature of binding multiple timers
4604 to a single thread actually works.
4606 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4608 * pthread.c (__pthread_create_2_1): Optimize a bit.
4610 * internals.h (invalid_handle): Also test for p_terminated != 0.
4611 (nonexisting_handle): New function. Same as old invalid_handle.
4612 * join.c (pthread_join): Use nonexisting_handle instead of
4613 invalid_handle to test for acceptable thread handle.
4614 * manager.c (pthread_handle_free): Likewise.
4615 * joinrace.c: New file.
4616 Reported by Permaine Cheung <pcheung@cygnus.com>.
4618 2000-06-08 Ulrich Drepper <drepper@redhat.com>
4620 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4621 Correct handling of matching variable.

4626 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4627 Be prepared for empty timer list.
4629 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
4630 CPUTIME clock ID. Add support for thread clocks.
4632 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
4633 subtraction were switched.
4635 * sysdeps/pthread/timer_routines.c (init_module): Use
4636 THREAD_MAXNODES threads.

4644 CLOCK_CPUTIME if _POSIX_CPUTIME is defined.
4646 * sysdeps/pthread/Makefile: New file. Add rules to build timer
4648 * sysdeps/unix/sysv/linux/bits/local_lim.h: Add TIMER_MAX.

4663 * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and
4664 LINK_MAX definitions if necessary.
4666 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
4668 Added missing fork time handling of global libio lock.
4670 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4671 not just the individual stream locks. Rewritten to use new
4672 iterator interface provided by libio rather than accessing
4675 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4676 which lock and unlock the stream list using the new interface
4678 * internals.h: Likewise.
4680 * ptfork.c (__fork): Now calls __flockfilelist before fork,
4681 and __funlockfilelist in the parent after the fork.
4682 Child still calls __fresetlockfiles as before.
4684 * linuxthreads.texi: Now explains what happens to streams at
4685 fork time. Also whole new section on forking and thread added.
4686 Definition of pthread_atfork moved out of Miscellaneous Functions
4687 to this new section.
4689 2000-06-04 Jakub Jelinek <jakub@redhat.com>

4712 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
4714 Bugfix: The pthread_atfork mechanism now takes care of its
4715 own internal mutex at fork time.
4717 * ptfork.c (__fork): Revised so that the mutex is held across
4718 the fork operation and while the handlers are called, and so that
4719 the child resets the mutex.
4721 * linuxthreads.texi: Updated pthread_atfork documentation to make
4722 it clear that fork and pthread_atfork can't be reentered from
4723 atfork handlers, that pthread_atfork and fork are mutually atomic,
4724 and that the handlers are inherited by the child process.
4726 2000-05-24 Ulrich Drepper <drepper@redhat.com>
4728 * Makefile (libpthread-routines): Add pspinlock.
4729 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

4765 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
4767 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4768 object state is represented with additional bits which distinguish
4769 whether that state was set up in the current process, or
4770 in an ancestor process. If that state was set in an ancestor,
4771 it means that a fork happened while thread was executing the init
4772 function. In that case, the state is reset to NEVER.
4773 * mutex.c (__pthread_once_fork_prepare): New function.
4774 (__pthread_once_fork_child): Likewise
4775 (__pthread_once_fork_parent): Likewise
4776 (__pthread_reset_pthread_once): Removed.

4783 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
4785 * internals.h: New thread manager request type, REQ_KICK.
4786 * join.c (pthread_exit): main thread now calls exit() instead
4787 of _exit() in order to proper process cleanup.
4788 * manager.c (__pthread_manager): Do not terminate manager
4789 after unblocking main thread; wait for main thread's
4790 REQ_PROCESS_EXIT request instead.
4791 Also, added REQ_KICK case to handle new request; this just does
4793 * manager.c (pthread_exited): Do not terminate manager after
4794 unblocking main thread.
4795 * manager.c (__pthread_manager_sighandler): If the main thread
4796 is waiting for all other threads to die, send a REQ_KICK into
4797 the thread manager request pipe to get it to clean out the threads
4798 and unblock the main thread as soon as possible. This fixes
4799 the 2000 millisecond hang on shutdown bug.
4800 * Examples/ex7.c: New file, tests shutdown behavior when all threads
4801 including the main one call pthread_exit(), or implicitly do so.
4802 * Makefile (tests): Add ex7.
4804 2000-05-05 Andreas Jaeger <aj@suse.de>

4828 minimal initialization.
4829 (pthread_initialize): Remove this code here.

5220 Redesigned how cancellation unblocks a thread from internal
5221 cancellation points (sem_wait, pthread_join,
5222 pthread_cond_{wait,timedwait}).
5223 Cancellation won't eat a signal in any of these functions
5224 (*required* by POSIX and Single Unix Spec!).
5225 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5226 simultaneous condition variable signal (not required by POSIX
5227 or Single Unix Spec, but nice).
5228 * spinlock.c: __pthread_lock queues back any received restarts
5229 that don't belong to it instead of assuming ownership of lock
5230 upon any restart; fastlock can no longer be acquired by two threads
5232 * restart.h: Restarts queue even on kernels that don't have
5233 queued real time signals (2.0, early 2.1), thanks to atomic counter,
5234 avoiding a rare race condition in pthread_cond_timedwait.

5276 pwrite64, lseek64, open64, and __open64.

5279 new_thread_bottom. Correct handling of stack size and when the
5280 rlimit method to guard for stack growth is used.
5281 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
5282 minus one pagesize (not two).
5284 1999-12-03 Andreas Jaeger <aj@suse.de>
5286 * Versions: Add __res_state with version GLIBC_2.2.

6494 Since sigset_t no longer fits in a register, we can't pass in the
6495 thread's initial mask so easily. Take this opportunity to simplify
6496 the clone implementation by only accepting a single void* argument.
6498 * manager.c (__pthread_manager): Put thread vitals in the thread
6499 struct instead of as arguments through clone.
6500 (pthread_start_thread): Look for them there.
6501 * internals.h (struct _pthread): Add p_initial_fn,
6502 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
6503 * pthread.c (pthread_initialize_manager): Revise clone invocation.
