916 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
918 Timer nodes are now reference counted, and can be marked
919 as deleted. This allows for the safe release of the global mutex
920 in the middle without losing the timer being operated on.
922 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
923 member is now an enum with three values, so that an intermediate
924 state can be represented (deleted but not free for reuse yet).
925 New refcount member added.

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

956 up timer thread unnecessarily.
958 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
959 inuse flag, because this requires mutex to be held. Callers updated
960 to do the check when they have the mutex.
961 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
963 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
964 regions: avoids making system calls while holding timer mutex, and
965 a few computations were moved outside of the mutex as well.
966 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
968 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
969 to list_unlink_ip, meaning idempotent. Pointer manipulation
970 changed to get better better code out of gcc.
971 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
972 version of list_unlink added here.
973 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
974 function in all places: idempotent one for timers, non-idempotent
975 one for thread nodes.
976 * sysdeps/pthread/timer_settime: Likewise.
977 * sysdeps/pthread/timer_routines.c: Likewise.
979 2000-06-13 Ulrich Drepper <drepper@redhat.com>

1013 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
1015 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
1017 * sysdeps/pthread/timer_create.c: Thread matching now done on
1018 clock type as well as thread attributes.
1019 There are individual global signal-delivering threads for
1020 different clock types.
1021 * sysdeps/pthread/posix-timer.h: Likewise.
1022 * sysdeps/pthread/timer_routines.c: Likewise.
1024 * sysdeps/pthread/timer_routines.c: Thread allocation and
1025 deallocation function now remembers to put thread on active
1026 list and remove from active list.
1027 Thus now the feature of binding multiple timers
1028 to a single thread actually works.
1030 2000-06-10 Ulrich Drepper <drepper@redhat.com>
1032 * pthread.c (__pthread_create_2_1): Optimize a bit.

1088 LINK_MAX definitions if necessary.
1090 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
1092 Added missing fork time handling of global libio lock.
1094 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
1095 not just the individual stream locks. Rewritten to use new
1096 iterator interface provided by libio rather than accessing
1099 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
1100 which lock and unlock the stream list using the new interface
1102 * internals.h: Likewise.
1104 * ptfork.c (__fork): Now calls __flockfilelist before fork,
1105 and __funlockfilelist in the parent after the fork.
1106 Child still calls __fresetlockfiles as before.

1138 Bugfix: The pthread_atfork mechanism now takes care of its
1139 own internal mutex at fork time.
1141 * ptfork.c (__fork): Revised so that the mutex is held across
1142 the fork operation and while the handlers are called, and so that
1143 the child resets the mutex.
1145 * linuxthreads.texi: Updated pthread_atfork documentation to make
1146 it clear that fork and pthread_atfork can't be reentered from
1147 atfork handlers, that pthread_atfork and fork are mutually atomic,
1148 and that the handlers are inherited by the child process.
1150 2000-05-24 Ulrich Drepper <drepper@redhat.com>
1152 * Makefile (libpthread-routines): Add pspinlock.
1153 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

1189 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
1191 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
1192 object state is represented with additional bits which distinguish
1193 whether that state was set up in the current process, or
1194 in an ancestor process. If that state was set in an ancestor,
1195 it means that a fork happened while thread was executing the init
1196 function. In that case, the state is reset to NEVER.
1197 * mutex.c (__pthread_once_fork_prepare): New function.
1198 (__pthread_once_fork_child): Likewise

1213 after unblocking main thread; wait for main thread's
1214 REQ_PROCESS_EXIT request instead.
1215 Also, added REQ_KICK case to handle new request; this just does
1217 * manager.c (pthread_exited): Do not terminate manager after
1218 unblocking main thread.
1219 * manager.c (__pthread_manager_sighandler): If the main thread
1220 is waiting for all other threads to die, send a REQ_KICK into
1221 the thread manager request pipe to get it to clean out the threads
1222 and unblock the main thread as soon as possible. This fixes
1223 the 2000 millisecond hang on shutdown bug.
1224 * Examples/ex7.c: New file, tests shutdown behavior when all threads
1225 including the main one call pthread_exit(), or implicitly do so.
1226 * Makefile (tests): Add ex7.

1308 if fast mutex is used. Don't initialize `already_canceled' twice.
1309 Correctly test for return value of timedsuspend.
1311 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
1312 therefore don't need the _rt versions of the signal handlers.

1618 2000-01-12 Ulrich Drepper <drepper@cygnus.com>
1620 * internals.h (pthread_readlock_info): New structure.
1621 (_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and
1622 p_untracked_readlock_count.
1623 * pthread.c (__pthread_initial_thread, pthread_manager_thread):
1624 Add initializers for new fields.
1625 * manager.c (pthread_free): Free read/write lock lists.
1626 * queue.h (queue_is_empty): New function.
1627 * rwlock.c: Implement requirements about when readers should get
1629 * sysdeps/pthread/pthread.h
1630 (PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP): New definition.
1631 * sysdeps/pthread/bits/pthreadtypes.h (struct _pthread_rwlock_t):
1632 Define this name as well.
1633 Patches by Kaz Kylheku <kaz@ashi.footprints.net>.
1635 2000-01-05 Ulrich Drepper <drepper@cygnus.com>
1637 * pthread.c (__pthread_initial_thread, pthread_manager_thread):
1638 Adjust initializers for struct _pthread_descr_struct change.
1639 * internals.h (struct _pthread_descr_struct): Move new elements to
1642 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net>
1644 Redesigned how cancellation unblocks a thread from internal
1645 cancellation points (sem_wait, pthread_join,
1646 pthread_cond_{wait,timedwait}).
1647 Cancellation won't eat a signal in any of these functions
1648 (*required* by POSIX and Single Unix Spec!).
1649 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
1650 simultaneous condition variable signal (not required by POSIX
1651 or Single Unix Spec, but nice).
1652 * spinlock.c: __pthread_lock queues back any received restarts
1653 that don't belong to it instead of assuming ownership of lock
1654 upon any restart; fastlock can no longer be acquired by two threads
1656 * restart.h: Restarts queue even on kernels that don't have
1657 queued real time signals (2.0, early 2.1), thanks to atomic counter,
1658 avoiding a rare race condition in pthread_cond_timedwait.
1660 1999-12-31 Andreas Jaeger <aj@suse.de>
1662 * internals.h: Remove duplicate prototype declarations.
1664 * weaks.c: Remove __THROW from prototypes since the file is not

1703 new_thread_bottom. Correct handling of stack size and when the
1704 rlimit method to guard for stack growth is used.
1705 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
1706 minus one pagesize (not two).
1708 1999-12-03 Andreas Jaeger <aj@suse.de>

1792 * pthread.c: For i386, wrap pthread_handle_sigrestart and
1793 pthread_handle_sigcancel with functions that restore %gs from the
