42 the lock->__status field.
44 * spinlock.c (__pthread_alt_timedlock): The oldstatus variable was
45 being set inappropriately, causing the suspend function to be called
46 with a null self pointer and crash.

311 Timer nodes are now reference counted, and can be marked
312 as deleted. This allows for the safe release of the global mutex
313 in the middle without losing the timer being operated on.
315 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
316 member is now an enum with three values, so that an intermediate
317 state can be represented (deleted but not free for reuse yet).

345 Returns int value now to indicate whether timer was queued at head.
346 * sysdeps/pthread/posix-timer.h: Likewise.

349 up timer thread unnecessarily.
351 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
352 inuse flag, because this requires mutex to be held. Callers updated
353 to do the check when they have the mutex.
354 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
356 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
357 regions: avoids making system calls while holding timer mutex, and
358 a few computations were moved outside of the mutex as well.
359 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
361 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
362 to list_unlink_ip, meaning idempotent. Pointer manipulation
363 changed to get better better code out of gcc.
364 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
365 version of list_unlink added here.
366 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
367 function in all places: idempotent one for timers, non-idempotent
368 one for thread nodes.
369 * sysdeps/pthread/timer_settime: Likewise.
370 * sysdeps/pthread/timer_routines.c: Likewise.
372 2000-06-13 Ulrich Drepper <drepper@redhat.com>

408 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
410 * sysdeps/pthread/timer_create.c: Thread matching now done on
411 clock type as well as thread attributes.
412 There are individual global signal-delivering threads for
413 different clock types.
414 * sysdeps/pthread/posix-timer.h: Likewise.
415 * sysdeps/pthread/timer_routines.c: Likewise.
417 * sysdeps/pthread/timer_routines.c: Thread allocation and
418 deallocation function now remembers to put thread on active
419 list and remove from active list.
420 Thus now the feature of binding multiple timers
421 to a single thread actually works.
423 2000-06-10 Ulrich Drepper <drepper@redhat.com>

483 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
485 Added missing fork time handling of global libio lock.
487 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
488 not just the individual stream locks. Rewritten to use new
489 iterator interface provided by libio rather than accessing
492 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
493 which lock and unlock the stream list using the new interface
495 * internals.h: Likewise.
497 * ptfork.c (__fork): Now calls __flockfilelist before fork,
498 and __funlockfilelist in the parent after the fork.
499 Child still calls __fresetlockfiles as before.
501 * linuxthreads.texi: Now explains what happens to streams at
502 fork time. Also whole new section on forking and thread added.
503 Definition of pthread_atfork moved out of Miscellaneous Functions

532 own internal mutex at fork time.
534 * ptfork.c (__fork): Revised so that the mutex is held across
535 the fork operation and while the handlers are called, and so that
536 the child resets the mutex.
538 * linuxthreads.texi: Updated pthread_atfork documentation to make
539 it clear that fork and pthread_atfork can't be reentered from
540 atfork handlers, that pthread_atfork and fork are mutually atomic,

578 2000-05-13 Jakub Jelinek <jakub@redhat.com>
580 * internals.h (__RES_PTHREAD_INTERNAL): Define.
582 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
584 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
585 object state is represented with additional bits which distinguish
586 whether that state was set up in the current process, or
587 in an ancestor process. If that state was set in an ancestor,
588 it means that a fork happened while thread was executing the init
589 function. In that case, the state is reset to NEVER.
590 * mutex.c (__pthread_once_fork_prepare): New function.
591 (__pthread_once_fork_child): Likewise

606 after unblocking main thread; wait for main thread's
607 REQ_PROCESS_EXIT request instead.
608 Also, added REQ_KICK case to handle new request; this just does
610 * manager.c (pthread_exited): Do not terminate manager after
611 unblocking main thread.
612 * manager.c (__pthread_manager_sighandler): If the main thread
613 is waiting for all other threads to die, send a REQ_KICK into
614 the thread manager request pipe to get it to clean out the threads
615 and unblock the main thread as soon as possible. This fixes
616 the 2000 millisecond hang on shutdown bug.
617 * Examples/ex7.c: New file, tests shutdown behavior when all threads
618 including the main one call pthread_exit(), or implicitly do so.

701 if fast mutex is used. Don't initialize `already_canceled' twice.
702 Correctly test for return value of timedsuspend.

1037 Redesigned how cancellation unblocks a thread from internal
1038 cancellation points (sem_wait, pthread_join,
1039 pthread_cond_{wait,timedwait}).
1040 Cancellation won't eat a signal in any of these functions
1041 (*required* by POSIX and Single Unix Spec!).
1042 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
1043 simultaneous condition variable signal (not required by POSIX
1044 or Single Unix Spec, but nice).
1045 * spinlock.c: __pthread_lock queues back any received restarts
1046 that don't belong to it instead of assuming ownership of lock
1047 upon any restart; fastlock can no longer be acquired by two threads
1049 * restart.h: Restarts queue even on kernels that don't have
1050 queued real time signals (2.0, early 2.1), thanks to atomic counter,
1051 avoiding a rare race condition in pthread_cond_timedwait.
1053 1999-12-31 Andreas Jaeger <aj@suse.de>

2313 Since sigset_t no longer fits in a register, we can't pass in the

2318 in the thread struct instead of as arguments through clone.

2321 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
