4378 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4380 A few optimizations. Got rid of unnecessary wakeups of timer threads,
4381 tightened up some critical regions and micro-optimized some list
4384 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4385 Returns int value now to indicate whether timer was queued at head.
4386 * sysdeps/pthread/posix-timer.h: Likewise.
4387 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4388 new return value from __timer_thread_queue_timer to avoid waking
4389 up timer thread unnecessarily.
4391 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4392 inuse flag, because this requires mutex to be held. Callers updated
4393 to do the check when they have the mutex.
4394 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4396 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4397 regions: avoids making system calls while holding timer mutex, and
4398 a few computations were moved outside of the mutex as well.
4399 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4401 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4402 to list_unlink_ip, meaning idempotent. Pointer manipulation
4403 changed to get better better code out of gcc.
4404 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4405 version of list_unlink added here.
4406 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4407 function in all places: idempotent one for timers, non-idempotent
4408 one for thread nodes.
4409 * sysdeps/pthread/timer_settime: Likewise.
4410 * sysdeps/pthread/timer_routines.c: Likewise.
4412 2000-06-13 Ulrich Drepper <drepper@redhat.com>
4414 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
4415 * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.

4442 really append the entry.
4444 2000-06-10 Andreas Jaeger <aj@suse.de>
4446 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
4448 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
4450 * sysdeps/pthread/timer_create.c: Thread matching now done on
4451 clock type as well as thread attributes.
4452 There are individual global signal-delivering threads for
4453 different clock types.
4454 * sysdeps/pthread/posix-timer.h: Likewise.
4455 * sysdeps/pthread/timer_routines.c: Likewise.
4457 * sysdeps/pthread/timer_routines.c: Thread allocation and
4458 deallocation function now remembers to put thread on active
4459 list and remove from active list.
4460 Thus now the feature of binding multiple timers
4461 to a single thread actually works.
4463 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4465 * pthread.c (__pthread_create_2_1): Optimize a bit.
4467 * internals.h (invalid_handle): Also test for p_terminated != 0.
4468 (nonexisting_handle): New function. Same as old invalid_handle.
4469 * join.c (pthread_join): Use nonexisting_handle instead of
4470 invalid_handle to test for acceptable thread handle.
4471 * manager.c (pthread_handle_free): Likewise.
4472 * joinrace.c: New file.
4473 Reported by Permaine Cheung <pcheung@cygnus.com>.

4478 Correct handling of matching variable.
4480 * sysdeps/pthread/tst-timer.c (main): Rewrite initializers to
4483 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4484 Be prepared for empty timer list.
4486 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
4487 CPUTIME clock ID. Add support for thread clocks.
4489 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
4490 subtraction were switched.
4492 * sysdeps/pthread/timer_routines.c (init_module): Use
4493 THREAD_MAXNODES threads.

4501 CLOCK_CPUTIME if _POSIX_CPUTIME is defined.
4503 * sysdeps/pthread/Makefile: New file. Add rules to build timer
4505 * sysdeps/unix/sysv/linux/bits/local_lim.h: Add TIMER_MAX.

4520 * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and
4521 LINK_MAX definitions if necessary.
4523 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
4525 Added missing fork time handling of global libio lock.
4527 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4528 not just the individual stream locks. Rewritten to use new
4529 iterator interface provided by libio rather than accessing
4532 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4533 which lock and unlock the stream list using the new interface
4535 * internals.h: Likewise.
4537 * ptfork.c (__fork): Now calls __flockfilelist before fork,
4538 and __funlockfilelist in the parent after the fork.
4539 Child still calls __fresetlockfiles as before.
4541 * linuxthreads.texi: Now explains what happens to streams at
4542 fork time. Also whole new section on forking and thread added.
4543 Definition of pthread_atfork moved out of Miscellaneous Functions
4544 to this new section.
4546 2000-06-04 Jakub Jelinek <jakub@redhat.com>
4548 * sysdeps/sparc/sparc32/sparcv9/pspinlock.c (__pthread_spin_lock):

4567 * Examples/ex8.c: New file.
4569 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
4571 Bugfix: The pthread_atfork mechanism now takes care of its
4572 own internal mutex at fork time.
4574 * ptfork.c (__fork): Revised so that the mutex is held across
4575 the fork operation and while the handlers are called, and so that
4576 the child resets the mutex.
4578 * linuxthreads.texi: Updated pthread_atfork documentation to make
4579 it clear that fork and pthread_atfork can't be reentered from
4580 atfork handlers, that pthread_atfork and fork are mutually atomic,
4581 and that the handlers are inherited by the child process.
4583 2000-05-24 Ulrich Drepper <drepper@redhat.com>
4585 * Makefile (libpthread-routines): Add pspinlock.
4586 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.
4587 Use struct _pthread_fastlock instead of pthread_spinlock_t.
4588 * condvar.c: Likewise.

4622 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
4624 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4625 object state is represented with additional bits which distinguish
4626 whether that state was set up in the current process, or
4627 in an ancestor process. If that state was set in an ancestor,
4628 it means that a fork happened while thread was executing the init
4629 function. In that case, the state is reset to NEVER.
4630 * mutex.c (__pthread_once_fork_prepare): New function.
4631 (__pthread_once_fork_child): Likewise
4632 (__pthread_once_fork_parent): Likewise
4633 (__pthread_reset_pthread_once): Removed.

4643 * join.c (pthread_exit): main thread now calls exit() instead
4644 of _exit() in order to proper process cleanup.
4645 * manager.c (__pthread_manager): Do not terminate manager
4646 after unblocking main thread; wait for main thread's
4647 REQ_PROCESS_EXIT request instead.
4648 Also, added REQ_KICK case to handle new request; this just does
4650 * manager.c (pthread_exited): Do not terminate manager after
4651 unblocking main thread.
4652 * manager.c (__pthread_manager_sighandler): If the main thread
4653 is waiting for all other threads to die, send a REQ_KICK into
4654 the thread manager request pipe to get it to clean out the threads
4655 and unblock the main thread as soon as possible. This fixes
4656 the 2000 millisecond hang on shutdown bug.
4657 * Examples/ex7.c: New file, tests shutdown behavior when all threads
4658 including the main one call pthread_exit(), or implicitly do so.
4659 * Makefile (tests): Add ex7.
4661 2000-05-05 Andreas Jaeger <aj@suse.de>

4692 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
4693 now. First gcc must be fixed (more concrete: libgcc).
4695 2000-04-24 Ulrich Drepper <drepper@redhat.com>
4697 * pthread.c: Remove special treatement for interrupt handlers on x86.
4698 * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.

4705 * join.c (pthread_exit): Set p_terminated after reporting the
4706 termination event instead of before.

4734 * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
4735 (pthread_getcpuclockid): Don't compare thread_id with thread_self,
4736 use thread_handle().
4738 2000-04-16 Ulrich Drepper <drepper@redhat.com>
4740 * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
4741 if fast mutex is used. Don't initialize `already_canceled' twice.
4742 Correctly test for return value of timedsuspend.
4744 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
4745 therefore don't need the _rt versions of the signal handlers.
4747 2000-04-15 Ulrich Drepper <drepper@redhat.com>
4749 * pthread.c (pthread_yield): New function.
4750 * sysdeps/pthread/pthread.h (pthread_yield): Add prototype.

5077 Redesigned how cancellation unblocks a thread from internal
5078 cancellation points (sem_wait, pthread_join,
5079 pthread_cond_{wait,timedwait}).
5080 Cancellation won't eat a signal in any of these functions
5081 (*required* by POSIX and Single Unix Spec!).
5082 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5083 simultaneous condition variable signal (not required by POSIX
5084 or Single Unix Spec, but nice).
5085 * spinlock.c: __pthread_lock queues back any received restarts
5086 that don't belong to it instead of assuming ownership of lock
5087 upon any restart; fastlock can no longer be acquired by two threads
5089 * restart.h: Restarts queue even on kernels that don't have
5090 queued real time signals (2.0, early 2.1), thanks to atomic counter,
5091 avoiding a rare race condition in pthread_cond_timedwait.

5136 new_thread_bottom. Correct handling of stack size and when the
5137 rlimit method to guard for stack growth is used.
5138 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
5139 minus one pagesize (not two).
