1 2000-08-10 Ulrich Drepper <drepper@redhat.com>
3 * pthread.c (__pthread_initial_thread): Initialize p_errnop and
4 p_h_errnop correctly and not to NULL.
6 2000-08-05 Ulrich Drepper <drepper@redhat.com>

43 * sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add
44 load of spin lock to prime the cache before the atomic compare and
45 exchange operation (cmpxchg4). This avoids the spinning on the
46 cmpxchg4 instruction and reduces movement of the cache line back
47 and forth between the processors (explanation by Asis K. Mallick
48 from Intel). This basically makes the implementation operate the
49 same as the Linux kernel implementation.
51 * shlib-versions: Use GLIBC_2_2 for Linux/ia64.

143 * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Wait
144 node was not being properly enqueued, due to failing to update
145 the lock->__status field.
147 * spinlock.c (__pthread_alt_timedlock): The oldstatus variable was
148 being set inappropriately, causing the suspend function to be called
149 with a null self pointer and crash.
151 2000-07-18 Ulrich Drepper <drepper@redhat.com>
153 * spinlock.h (__pthread_alt_trylock): Fix code used if no
154 compare&swap is available.

416 in the middle without losing the timer being operated on.
418 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
419 member is now an enum with three values, so that an intermediate

455 inuse flag, because this requires mutex to be held. Callers updated
456 to do the check when they have the mutex.
457 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
459 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
460 regions: avoids making system calls while holding timer mutex, and
461 a few computations were moved outside of the mutex as well.

468 version of list_unlink added here.
469 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
470 function in all places: idempotent one for timers, non-idempotent
471 one for thread nodes.
472 * sysdeps/pthread/timer_settime: Likewise.
473 * sysdeps/pthread/timer_routines.c: Likewise.
475 2000-06-13 Ulrich Drepper <drepper@redhat.com>

511 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
513 * sysdeps/pthread/timer_create.c: Thread matching now done on
514 clock type as well as thread attributes.
515 There are individual global signal-delivering threads for
516 different clock types.
517 * sysdeps/pthread/posix-timer.h: Likewise.
518 * sysdeps/pthread/timer_routines.c: Likewise.
520 * sysdeps/pthread/timer_routines.c: Thread allocation and

588 Added missing fork time handling of global libio lock.
590 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
591 not just the individual stream locks. Rewritten to use new
592 iterator interface provided by libio rather than accessing
595 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
596 which lock and unlock the stream list using the new interface
598 * internals.h: Likewise.

634 Bugfix: The pthread_atfork mechanism now takes care of its
635 own internal mutex at fork time.
637 * ptfork.c (__fork): Revised so that the mutex is held across
638 the fork operation and while the handlers are called, and so that
639 the child resets the mutex.
641 * linuxthreads.texi: Updated pthread_atfork documentation to make
642 it clear that fork and pthread_atfork can't be reentered from
643 atfork handlers, that pthread_atfork and fork are mutually atomic,
644 and that the handlers are inherited by the child process.
646 2000-05-24 Ulrich Drepper <drepper@redhat.com>
648 * Makefile (libpthread-routines): Add pspinlock.

688 object state is represented with additional bits which distinguish
689 whether that state was set up in the current process, or
690 in an ancestor process. If that state was set in an ancestor,
691 it means that a fork happened while thread was executing the init
692 function. In that case, the state is reset to NEVER.
693 * mutex.c (__pthread_once_fork_prepare): New function.
694 (__pthread_once_fork_child): Likewise

710 REQ_PROCESS_EXIT request instead.
711 Also, added REQ_KICK case to handle new request; this just does
713 * manager.c (pthread_exited): Do not terminate manager after
714 unblocking main thread.
715 * manager.c (__pthread_manager_sighandler): If the main thread
716 is waiting for all other threads to die, send a REQ_KICK into
717 the thread manager request pipe to get it to clean out the threads
718 and unblock the main thread as soon as possible. This fixes
719 the 2000 millisecond hang on shutdown bug.
720 * Examples/ex7.c: New file, tests shutdown behavior when all threads
721 including the main one call pthread_exit(), or implicitly do so.
722 * Makefile (tests): Add ex7.

1112 Patches by Kaz Kylheku <kaz@ashi.footprints.net>.
1114 2000-01-12 Ulrich Drepper <drepper@cygnus.com>
1116 * internals.h (pthread_readlock_info): New structure.
1117 (_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and
1118 p_untracked_readlock_count.
1119 * pthread.c (__pthread_initial_thread, pthread_manager_thread):
1120 Add initializers for new fields.

1138 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net>
1140 Redesigned how cancellation unblocks a thread from internal
1141 cancellation points (sem_wait, pthread_join,
1142 pthread_cond_{wait,timedwait}).
1143 Cancellation won't eat a signal in any of these functions
1144 (*required* by POSIX and Single Unix Spec!).
1145 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
1146 simultaneous condition variable signal (not required by POSIX
1147 or Single Unix Spec, but nice).
1148 * spinlock.c: __pthread_lock queues back any received restarts
1149 that don't belong to it instead of assuming ownership of lock
1150 upon any restart; fastlock can no longer be acquired by two threads
1152 * restart.h: Restarts queue even on kernels that don't have
1153 queued real time signals (2.0, early 2.1), thanks to atomic counter,
1154 avoiding a rare race condition in pthread_cond_timedwait.
1156 1999-12-31 Andreas Jaeger <aj@suse.de>
1158 * internals.h: Remove duplicate prototype declarations.

1199 new_thread_bottom. Correct handling of stack size and when the
1200 rlimit method to guard for stack growth is used.
1201 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
1202 minus one pagesize (not two).

1288 * pthread.c: For i386, wrap pthread_handle_sigrestart and
1289 pthread_handle_sigcancel with functions that restore %gs from the
