64 being set inappropriately, causing the suspend function to be called
65 with a null self pointer and crash.

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

363 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
364 Returns int value now to indicate whether timer was queued at head.
365 * sysdeps/pthread/posix-timer.h: Likewise.
366 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
367 new return value from __timer_thread_queue_timer to avoid waking
368 up timer thread unnecessarily.
370 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
371 inuse flag, because this requires mutex to be held. Callers updated
372 to do the check when they have the mutex.
373 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
375 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
376 regions: avoids making system calls while holding timer mutex, and
377 a few computations were moved outside of the mutex as well.
378 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
380 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
381 to list_unlink_ip, meaning idempotent. Pointer manipulation
382 changed to get better better code out of gcc.
383 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
384 version of list_unlink added here.
385 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
386 function in all places: idempotent one for timers, non-idempotent
387 one for thread nodes.
388 * sysdeps/pthread/timer_settime: Likewise.
389 * sysdeps/pthread/timer_routines.c: Likewise.
391 2000-06-13 Ulrich Drepper <drepper@redhat.com>

425 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
427 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
429 * sysdeps/pthread/timer_create.c: Thread matching now done on
430 clock type as well as thread attributes.
431 There are individual global signal-delivering threads for
432 different clock types.
433 * sysdeps/pthread/posix-timer.h: Likewise.
434 * sysdeps/pthread/timer_routines.c: Likewise.
436 * sysdeps/pthread/timer_routines.c: Thread allocation and
437 deallocation function now remembers to put thread on active
438 list and remove from active list.
439 Thus now the feature of binding multiple timers
440 to a single thread actually works.
442 2000-06-10 Ulrich Drepper <drepper@redhat.com>

500 LINK_MAX definitions if necessary.
502 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
504 Added missing fork time handling of global libio lock.
506 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
507 not just the individual stream locks. Rewritten to use new
508 iterator interface provided by libio rather than accessing
511 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
512 which lock and unlock the stream list using the new interface
514 * internals.h: Likewise.
516 * ptfork.c (__fork): Now calls __flockfilelist before fork,
517 and __funlockfilelist in the parent after the fork.
518 Child still calls __fresetlockfiles as before.
520 * linuxthreads.texi: Now explains what happens to streams at
521 fork time. Also whole new section on forking and thread added.
522 Definition of pthread_atfork moved out of Miscellaneous Functions

551 own internal mutex at fork time.
553 * ptfork.c (__fork): Revised so that the mutex is held across
554 the fork operation and while the handlers are called, and so that
555 the child resets the mutex.
557 * linuxthreads.texi: Updated pthread_atfork documentation to make
558 it clear that fork and pthread_atfork can't be reentered from
559 atfork handlers, that pthread_atfork and fork are mutually atomic,

597 2000-05-13 Jakub Jelinek <jakub@redhat.com>
599 * internals.h (__RES_PTHREAD_INTERNAL): Define.
601 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
603 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
604 object state is represented with additional bits which distinguish
605 whether that state was set up in the current process, or
606 in an ancestor process. If that state was set in an ancestor,
607 it means that a fork happened while thread was executing the init
608 function. In that case, the state is reset to NEVER.
609 * mutex.c (__pthread_once_fork_prepare): New function.
610 (__pthread_once_fork_child): Likewise

625 after unblocking main thread; wait for main thread's
626 REQ_PROCESS_EXIT request instead.
627 Also, added REQ_KICK case to handle new request; this just does
629 * manager.c (pthread_exited): Do not terminate manager after
630 unblocking main thread.
631 * manager.c (__pthread_manager_sighandler): If the main thread
632 is waiting for all other threads to die, send a REQ_KICK into
633 the thread manager request pipe to get it to clean out the threads
634 and unblock the main thread as soon as possible. This fixes
635 the 2000 millisecond hang on shutdown bug.
636 * Examples/ex7.c: New file, tests shutdown behavior when all threads
637 including the main one call pthread_exit(), or implicitly do so.

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

724 therefore don't need the _rt versions of the signal handlers.

1054 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net>
1056 Redesigned how cancellation unblocks a thread from internal
1057 cancellation points (sem_wait, pthread_join,
1058 pthread_cond_{wait,timedwait}).
1059 Cancellation won't eat a signal in any of these functions
1060 (*required* by POSIX and Single Unix Spec!).
1061 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
1062 simultaneous condition variable signal (not required by POSIX
1063 or Single Unix Spec, but nice).
1064 * spinlock.c: __pthread_lock queues back any received restarts
1065 that don't belong to it instead of assuming ownership of lock
1066 upon any restart; fastlock can no longer be acquired by two threads
1068 * restart.h: Restarts queue even on kernels that don't have
1069 queued real time signals (2.0, early 2.1), thanks to atomic counter,
1070 avoiding a rare race condition in pthread_cond_timedwait.
1072 1999-12-31 Andreas Jaeger <aj@suse.de>

2332 Since sigset_t no longer fits in a register, we can't pass in the
