496
497 * sysdeps/unix/sysv/linux/bits/posix_opt.h: Define _POSIX_SEMAPHORES
498 even though the implementation is not quite complete (but it reports
499 it). Define _POSIX_MESSAGE_PASSING to -1.
500 * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.

528 (pthread_allocate_stack): Allow kernel to choose stack address if
529 FLOATING_STACKS. This also handles variable-sized stacks.
530 Always allocate stack and guardpage together. Use mprotect to
531 change guardpage access.

551 * sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add
552 load of spin lock to prime the cache before the atomic compare and
553 exchange operation (cmpxchg4). This avoids the spinning on the
554 cmpxchg4 instruction and reduces movement of the cache line back
555 and forth between the processors (explanation by Asis K. Mallick
556 from Intel). This basically makes the implementation operate the
557 same as the Linux kernel implementation.
558
559 * shlib-versions: Use GLIBC_2_2 for Linux/ia64.
560 * sysdeps/ia64/pspinlock.c: New file.

649 and swap.
650
651 * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Wait
652 node was not being properly enqueued, due to failing to update
653 the lock->__status field.
654
655 * spinlock.c (__pthread_alt_timedlock): The oldstatus variable was
656 being set inappropriately, causing the suspend function to be called

922 Timer nodes are now reference counted, and can be marked
923 as deleted. This allows for the safe release of the global mutex
924 in the middle without losing the timer being operated on.
925
926 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
927 member is now an enum with three values, so that an intermediate
928 state can be represented (deleted but not free for reuse yet).
929 New refcount member added.

956 Returns int value now to indicate whether timer was queued at head.
957 * sysdeps/pthread/posix-timer.h: Likewise.
958 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
959 new return value from __timer_thread_queue_timer to avoid waking
960 up timer thread unnecessarily.
961
962 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
963 inuse flag, because this requires mutex to be held. Callers updated
964 to do the check when they have the mutex.
965 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
966
967 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
968 regions: avoids making system calls while holding timer mutex, and
969 a few computations were moved outside of the mutex as well.
970 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
971
972 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
973 to list_unlink_ip, meaning idempotent. Pointer manipulation
974 changed to get better better code out of gcc.
975 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
976 version of list_unlink added here.
977 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
978 function in all places: idempotent one for timers, non-idempotent
979 one for thread nodes.
980 * sysdeps/pthread/timer_settime: Likewise.
981 * sysdeps/pthread/timer_routines.c: Likewise.
982

1019 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
1020
1021 * sysdeps/pthread/timer_create.c: Thread matching now done on
1022 clock type as well as thread attributes.
1023 There are individual global signal-delivering threads for
1024 different clock types.
1025 * sysdeps/pthread/posix-timer.h: Likewise.
1026 * sysdeps/pthread/timer_routines.c: Likewise.
1027
1028 * sysdeps/pthread/timer_routines.c: Thread allocation and
1029 deallocation function now remembers to put thread on active
1030 list and remove from active list.
1031 Thus now the feature of binding multiple timers
1032 to a single thread actually works.
1033
1034 2000-06-10 Ulrich Drepper <drepper@redhat.com>
1035
1036 * pthread.c (__pthread_create_2_1): Optimize a bit.

1092 LINK_MAX definitions if necessary.
1093
1094 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
1095
1096 Added missing fork time handling of global libio lock.
1097
1098 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
1099 not just the individual stream locks. Rewritten to use new
1100 iterator interface provided by libio rather than accessing
1101 global variable.
1102
1103 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
1104 which lock and unlock the stream list using the new interface
1105 provied by libio.
1106 * internals.h: Likewise.
1107
1108 * ptfork.c (__fork): Now calls __flockfilelist before fork,
1109 and __funlockfilelist in the parent after the fork.
1110 Child still calls __fresetlockfiles as before.
1111
1112 * linuxthreads.texi: Now explains what happens to streams at
1113 fork time. Also whole new section on forking and thread added.
1114 Definition of pthread_atfork moved out of Miscellaneous Functions
1115 to this new section.
1116
1117 2000-06-04 Jakub Jelinek <jakub@redhat.com>
1118
1119 * sysdeps/sparc/sparc32/sparcv9/pspinlock.c (__pthread_spin_lock):

1139
1140 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
1141
1142 Bugfix: The pthread_atfork mechanism now takes care of its
1143 own internal mutex at fork time.
1144
1145 * ptfork.c (__fork): Revised so that the mutex is held across
1146 the fork operation and while the handlers are called, and so that
1147 the child resets the mutex.
1148
1149 * linuxthreads.texi: Updated pthread_atfork documentation to make
1150 it clear that fork and pthread_atfork can't be reentered from
1151 atfork handlers, that pthread_atfork and fork are mutually atomic,
1152 and that the handlers are inherited by the child process.
1153
1154 2000-05-24 Ulrich Drepper <drepper@redhat.com>
1155
1156 * Makefile (libpthread-routines): Add pspinlock.

1179 back to _pthread_fastlock. Define new pthread_spinlock_t.
1180
1181 2000-05-24 Andreas Jaeger <aj@suse.de>

1192
1193 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
1194
1195 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
1196 object state is represented with additional bits which distinguish
1197 whether that state was set up in the current process, or
1198 in an ancestor process. If that state was set in an ancestor,
1199 it means that a fork happened while thread was executing the init
1200 function. In that case, the state is reset to NEVER.
1201 * mutex.c (__pthread_once_fork_prepare): New function.
1202 (__pthread_once_fork_child): Likewise
1203 (__pthread_once_fork_parent): Likewise
1204 (__pthread_reset_pthread_once): Removed.

1209 to clarify what happens under cancellation and forking.
1210
1211 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
1212
1213 * internals.h: New thread manager request type, REQ_KICK.
1214 * join.c (pthread_exit): main thread now calls exit() instead
1215 of _exit() in order to proper process cleanup.
1216 * manager.c (__pthread_manager): Do not terminate manager
1217 after unblocking main thread; wait for main thread's
1218 REQ_PROCESS_EXIT request instead.
1219 Also, added REQ_KICK case to handle new request; this just does
1220 nothing.
1221 * manager.c (pthread_exited): Do not terminate manager after
1222 unblocking main thread.
1223 * manager.c (__pthread_manager_sighandler): If the main thread
1224 is waiting for all other threads to die, send a REQ_KICK into
1225 the thread manager request pipe to get it to clean out the threads
1226 and unblock the main thread as soon as possible. This fixes
1227 the 2000 millisecond hang on shutdown bug.
1228 * Examples/ex7.c: New file, tests shutdown behavior when all threads
1229 including the main one call pthread_exit(), or implicitly do so.
1230 * Makefile (tests): Add ex7.

1236
1237 2000-05-05 Ulrich Drepper <drepper@redhat.com>
1238
1239 * internals.h (struct _pthread_descr_struct): Reorganization.
1240 Allocate room for 16 pointers at head of the structure for future
1241 thread-local data handling. Move p_self member in this area.
1242 * manager.c (pthread_handle_create): Adjust use of p_self.
1243 * sysdeps/i386/useldt.h (THREAD_SELF): Likewise.
1244 * pthread.c (__pthread_initial_thread): Adjust initialization.
1245 (__pthread_manager_thread): Likewise.
1246
1247 2000-04-29 Bruno Haible <haible@clisp.cons.org>

1256 minimal initialization.
1257 (pthread_initialize): Remove this code here.
1258 * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again. We
1259 are working around the problem in glibc.
1260
1261 2000-04-25 Ulrich Drepper <drepper@redhat.com>
1262
1263 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
1264 now. First gcc must be fixed (more concrete: libgcc).
1265
1266 2000-04-24 Ulrich Drepper <drepper@redhat.com>
1267
1268 * pthread.c: Remove special treatement for interrupt handlers on x86.

1273
1274 2000-04-24 Mark Kettenis <kettenis@gnu.org>
1275
1276 * join.c (pthread_exit): Set p_terminated after reporting the

1301 headers.
1302
1303 2000-04-17 Ulrich Drepper <drepper@redhat.com>
1304
1305 * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
1306 (pthread_getcpuclockid): Don't compare thread_id with thread_self,
1307 use thread_handle().
1308
1309 2000-04-16 Ulrich Drepper <drepper@redhat.com>
1310
1311 * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
1312 if fast mutex is used. Don't initialize `already_canceled' twice.
1313 Correctly test for return value of timedsuspend.
1314
1315 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
1316 therefore don't need the _rt versions of the signal handlers.

1329 to dynamically detect RT signals and avoid generating compatibility
1330 functions with old kernel.

1332 __pthread_restart_new directly.
1333 (suspend) [__ASSUME_REALTIME_SIGNALS]: Use

1648 Redesigned how cancellation unblocks a thread from internal
1649 cancellation points (sem_wait, pthread_join,
1650 pthread_cond_{wait,timedwait}).
1651 Cancellation won't eat a signal in any of these functions
1652 (*required* by POSIX and Single Unix Spec!).
1653 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
1654 simultaneous condition variable signal (not required by POSIX
1655 or Single Unix Spec, but nice).
1656 * spinlock.c: __pthread_lock queues back any received restarts
1657 that don't belong to it instead of assuming ownership of lock
1658 upon any restart; fastlock can no longer be acquired by two threads
1659 simultaneously.
1660 * restart.h: Restarts queue even on kernels that don't have
1661 queued real time signals (2.0, early 2.1), thanks to atomic counter,
1662 avoiding a rare race condition in pthread_cond_timedwait.
1663

1704 pwrite64, lseek64, open64, and __open64.
1705
1706 * manager.c (pthread_allocate_stack): Correct computation of
1707 new_thread_bottom. Correct handling of stack size and when the
1708 rlimit method to guard for stack growth is used.
1709 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
1710 minus one pagesize (not two).
1711
1712 1999-12-03 Andreas Jaeger <aj@suse.de>
1713
1714 * Versions: Add __res_state with version GLIBC_2.2.

2921
2922 Since sigset_t no longer fits in a register, we can't pass in the
2923 thread's initial mask so easily. Take this opportunity to simplify
2924 the clone implementation by only accepting a single void* argument.
2925
2926 * manager.c (__pthread_manager): Put thread vitals in the thread
2927 struct instead of as arguments through clone.

2929 * internals.h (struct _pthread): Add p_initial_fn,
2930 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
2931 * pthread.c (pthread_initialize_manager): Revise clone invocation.
