571 1 to avoid removing the stack.
573 2000-07-27 Jes Sorensen <jes@linuxcare.com>
575 * sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add
576 load of spin lock to prime the cache before the atomic compare and
577 exchange operation (cmpxchg4). This avoids the spinning on the
578 cmpxchg4 instruction and reduces movement of the cache line back
579 and forth between the processors (explanation by Asis K. Mallick
580 from Intel). This basically makes the implementation operate the
581 same as the Linux kernel implementation.
583 * shlib-versions: Use GLIBC_2_2 for Linux/ia64.

675 * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Wait
676 node was not being properly enqueued, due to failing to update
677 the lock->__status field.
679 * spinlock.c (__pthread_alt_timedlock): The oldstatus variable was
680 being set inappropriately, causing the suspend function to be called
681 with a null self pointer and crash.
683 2000-07-18 Ulrich Drepper <drepper@redhat.com>
685 * spinlock.h (__pthread_alt_trylock): Fix code used if no

944 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
946 Timer nodes are now reference counted, and can be marked
947 as deleted. This allows for the safe release of the global mutex
948 in the middle without losing the timer being operated on.
950 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
951 member is now an enum with three values, so that an intermediate
952 state can be represented (deleted but not free for reuse yet).
953 New refcount member added.

980 Returns int value now to indicate whether timer was queued at head.
981 * sysdeps/pthread/posix-timer.h: Likewise.
982 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
983 new return value from __timer_thread_queue_timer to avoid waking
984 up timer thread unnecessarily.
986 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
987 inuse flag, because this requires mutex to be held. Callers updated
988 to do the check when they have the mutex.
989 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
991 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
992 regions: avoids making system calls while holding timer mutex, and
993 a few computations were moved outside of the mutex as well.
994 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
996 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
997 to list_unlink_ip, meaning idempotent. Pointer manipulation
998 changed to get better better code out of gcc.
999 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
1000 version of list_unlink added here.
1001 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
1002 function in all places: idempotent one for timers, non-idempotent
1003 one for thread nodes.
1004 * sysdeps/pthread/timer_settime: Likewise.
1005 * sysdeps/pthread/timer_routines.c: Likewise.
1007 2000-06-13 Ulrich Drepper <drepper@redhat.com>

1041 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
1043 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
1045 * sysdeps/pthread/timer_create.c: Thread matching now done on
1046 clock type as well as thread attributes.
1047 There are individual global signal-delivering threads for
1048 different clock types.
1049 * sysdeps/pthread/posix-timer.h: Likewise.
1050 * sysdeps/pthread/timer_routines.c: Likewise.
1052 * sysdeps/pthread/timer_routines.c: Thread allocation and
1053 deallocation function now remembers to put thread on active
1054 list and remove from active list.
1055 Thus now the feature of binding multiple timers
1056 to a single thread actually works.
1058 2000-06-10 Ulrich Drepper <drepper@redhat.com>
1060 * pthread.c (__pthread_create_2_1): Optimize a bit.

1122 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
1123 not just the individual stream locks. Rewritten to use new
1124 iterator interface provided by libio rather than accessing
1127 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
1128 which lock and unlock the stream list using the new interface
1130 * internals.h: Likewise.
1132 * ptfork.c (__fork): Now calls __flockfilelist before fork,
1133 and __funlockfilelist in the parent after the fork.
1134 Child still calls __fresetlockfiles as before.
1136 * linuxthreads.texi: Now explains what happens to streams at
1137 fork time. Also whole new section on forking and thread added.

1164 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
1166 Bugfix: The pthread_atfork mechanism now takes care of its
1167 own internal mutex at fork time.
1169 * ptfork.c (__fork): Revised so that the mutex is held across
1170 the fork operation and while the handlers are called, and so that
1171 the child resets the mutex.
1173 * linuxthreads.texi: Updated pthread_atfork documentation to make
1174 it clear that fork and pthread_atfork can't be reentered from
1175 atfork handlers, that pthread_atfork and fork are mutually atomic,
1176 and that the handlers are inherited by the child process.
1178 2000-05-24 Ulrich Drepper <drepper@redhat.com>
1180 * Makefile (libpthread-routines): Add pspinlock.
1181 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

1217 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
1219 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
1220 object state is represented with additional bits which distinguish
1221 whether that state was set up in the current process, or
1222 in an ancestor process. If that state was set in an ancestor,
1223 it means that a fork happened while thread was executing the init
1224 function. In that case, the state is reset to NEVER.
1225 * mutex.c (__pthread_once_fork_prepare): New function.
1226 (__pthread_once_fork_child): Likewise

1241 after unblocking main thread; wait for main thread's
1242 REQ_PROCESS_EXIT request instead.
1243 Also, added REQ_KICK case to handle new request; this just does
1245 * manager.c (pthread_exited): Do not terminate manager after
1246 unblocking main thread.
1247 * manager.c (__pthread_manager_sighandler): If the main thread
1248 is waiting for all other threads to die, send a REQ_KICK into
1249 the thread manager request pipe to get it to clean out the threads
1250 and unblock the main thread as soon as possible. This fixes
1251 the 2000 millisecond hang on shutdown bug.
1252 * Examples/ex7.c: New file, tests shutdown behavior when all threads
1253 including the main one call pthread_exit(), or implicitly do so.
1254 * Makefile (tests): Add ex7.
1256 2000-05-05 Andreas Jaeger <aj@suse.de>

1336 if fast mutex is used. Don't initialize `already_canceled' twice.
1337 Correctly test for return value of timedsuspend.
1339 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
1340 therefore don't need the _rt versions of the signal handlers.

1672 Redesigned how cancellation unblocks a thread from internal
1673 cancellation points (sem_wait, pthread_join,
1674 pthread_cond_{wait,timedwait}).
1675 Cancellation won't eat a signal in any of these functions
1676 (*required* by POSIX and Single Unix Spec!).
1677 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
1678 simultaneous condition variable signal (not required by POSIX
1679 or Single Unix Spec, but nice).
1680 * spinlock.c: __pthread_lock queues back any received restarts
1681 that don't belong to it instead of assuming ownership of lock
1682 upon any restart; fastlock can no longer be acquired by two threads
1684 * restart.h: Restarts queue even on kernels that don't have
1685 queued real time signals (2.0, early 2.1), thanks to atomic counter,
1686 avoiding a rare race condition in pthread_cond_timedwait.
1688 1999-12-31 Andreas Jaeger <aj@suse.de>

1731 new_thread_bottom. Correct handling of stack size and when the
1732 rlimit method to guard for stack growth is used.
1733 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
1734 minus one pagesize (not two).

1820 * pthread.c: For i386, wrap pthread_handle_sigrestart and
1821 pthread_handle_sigcancel with functions that restore %gs from the
