1102 Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
1104 2000-06-19 H.J. Lu <hjl@gnu.org>
1106 * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
1107 HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
1108 (compare_and_swap_with_release_semantics): New. Default to
1109 compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
1112 * spinlock.c (__pthread_unlock): Call
1113 compare_and_swap_with_release_semantics () instead of
1114 compare_and_swap ().
1116 2000-06-19 Ulrich Drepper <drepper@redhat.com>
1118 * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning
1120 * sysdeps/pthread/timer_delete.c: Likewise.
1121 * sysdeps/pthread/timer_getoverr.c: Likewise.

1125 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
1127 Timer nodes are now reference counted, and can be marked
1128 as deleted. This allows for the safe release of the global mutex
1129 in the middle without losing the timer being operated on.
1131 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
1132 member is now an enum with three values, so that an intermediate
1133 state can be represented (deleted but not free for reuse yet).
1134 New refcount member added.
1135 * sysdeps/pthread/timer_routines.c: Likewise.
1137 * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
1138 timer_valid): New inline functions added.
1140 * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
1141 restructured, recursive deadlock bug fixed.
1143 * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
1144 timer_addref to ensure that timer won't be deleted while mutex is not
1145 held. Also uses timer_invalid to perform validation of timer handle.
1146 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
1147 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
1149 2000-06-14 Ulrich Drepper <drepper@redhat.com>
1151 * shlib-versions: Add entry for SH.
1152 Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
1154 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
1156 A few optimizations. Got rid of unnecessary wakeups of timer threads,
1157 tightened up some critical regions and micro-optimized some list
1160 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
1161 Returns int value now to indicate whether timer was queued at head.
1162 * sysdeps/pthread/posix-timer.h: Likewise.
1163 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
1164 new return value from __timer_thread_queue_timer to avoid waking
1165 up timer thread unnecessarily.
1167 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
1168 inuse flag, because this requires mutex to be held. Callers updated
1169 to do the check when they have the mutex.
1170 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
1172 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
1173 regions: avoids making system calls while holding timer mutex, and
1174 a few computations were moved outside of the mutex as well.
1175 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
1177 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
1178 to list_unlink_ip, meaning idempotent. Pointer manipulation
1179 changed to get better better code out of gcc.
1180 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
1181 version of list_unlink added here.
1182 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
1183 function in all places: idempotent one for timers, non-idempotent
1184 one for thread nodes.
1185 * sysdeps/pthread/timer_settime: Likewise.
1186 * sysdeps/pthread/timer_routines.c: Likewise.
1188 2000-06-13 Ulrich Drepper <drepper@redhat.com>
1190 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
1191 * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.

1217 * sysdeps/pthread/timer_routines.c (list_append): Little fix to
1218 really append the entry.
1220 2000-06-10 Andreas Jaeger <aj@suse.de>
1222 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
1224 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
1226 * sysdeps/pthread/timer_create.c: Thread matching now done on
1227 clock type as well as thread attributes.
1228 There are individual global signal-delivering threads for
1229 different clock types.
1230 * sysdeps/pthread/posix-timer.h: Likewise.
1231 * sysdeps/pthread/timer_routines.c: Likewise.
1233 * sysdeps/pthread/timer_routines.c: Thread allocation and
1234 deallocation function now remembers to put thread on active
1235 list and remove from active list.
1236 Thus now the feature of binding multiple timers
1237 to a single thread actually works.
1239 2000-06-10 Ulrich Drepper <drepper@redhat.com>
1241 * pthread.c (__pthread_create_2_1): Optimize a bit.
1243 * internals.h (invalid_handle): Also test for p_terminated != 0.
1244 (nonexisting_handle): New function. Same as old invalid_handle.
1245 * join.c (pthread_join): Use nonexisting_handle instead of
1246 invalid_handle to test for acceptable thread handle.
1247 * manager.c (pthread_handle_free): Likewise.
1248 * joinrace.c: New file.
1249 Reported by Permaine Cheung <pcheung@cygnus.com>.
1251 2000-06-08 Ulrich Drepper <drepper@redhat.com>
1253 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
1254 Correct handling of matching variable.

1259 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
1260 Be prepared for empty timer list.
1262 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
1263 CPUTIME clock ID. Add support for thread clocks.
1265 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
1266 subtraction were switched.
1268 * sysdeps/pthread/timer_routines.c (init_module): Use
1269 THREAD_MAXNODES threads.
1271 * sysdeps/pthread/posix-timer.h (struct timer_node): Add creator_pid.
1272 * sysdeps/pthread/timer_create.c: Fill in creator_pid.
1273 * sysdeps/pthread/timer_routines.c (thread_expire_timer): Send signal
1274 with sigqueueinfo is this system call is available.
1276 * sysdeps/pthread/timer_create.c (timer_create): Allow
1277 CLOCK_CPUTIME if _POSIX_CPUTIME is defined.
1279 * sysdeps/pthread/Makefile: New file. Add rules to build timer
1281 * sysdeps/unix/sysv/linux/bits/local_lim.h: Add TIMER_MAX.

1296 * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and
1297 LINK_MAX definitions if necessary.
1299 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
1301 Added missing fork time handling of global libio lock.
1303 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
1304 not just the individual stream locks. Rewritten to use new
1305 iterator interface provided by libio rather than accessing
1308 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
1309 which lock and unlock the stream list using the new interface
1311 * internals.h: Likewise.
1313 * ptfork.c (__fork): Now calls __flockfilelist before fork,
1314 and __funlockfilelist in the parent after the fork.
1315 Child still calls __fresetlockfiles as before.
1317 * linuxthreads.texi: Now explains what happens to streams at
1318 fork time. Also whole new section on forking and thread added.
1319 Definition of pthread_atfork moved out of Miscellaneous Functions
1320 to this new section.
1322 2000-06-04 Jakub Jelinek <jakub@redhat.com>

1343 * Examples/ex8.c: New file.
1345 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
1347 Bugfix: The pthread_atfork mechanism now takes care of its
1348 own internal mutex at fork time.
1350 * ptfork.c (__fork): Revised so that the mutex is held across
1351 the fork operation and while the handlers are called, and so that
1352 the child resets the mutex.
1354 * linuxthreads.texi: Updated pthread_atfork documentation to make
1355 it clear that fork and pthread_atfork can't be reentered from
1356 atfork handlers, that pthread_atfork and fork are mutually atomic,
1357 and that the handlers are inherited by the child process.
1359 2000-05-24 Ulrich Drepper <drepper@redhat.com>
1361 * Makefile (libpthread-routines): Add pspinlock.
1362 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.
1363 Use struct _pthread_fastlock instead of pthread_spinlock_t.
1364 * condvar.c: Likewise.
1365 * internals.h: Likewise.

1396 * internals.h (__RES_PTHREAD_INTERNAL): Define.
1398 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
1400 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
1401 object state is represented with additional bits which distinguish
1402 whether that state was set up in the current process, or
1403 in an ancestor process. If that state was set in an ancestor,
1404 it means that a fork happened while thread was executing the init
1405 function. In that case, the state is reset to NEVER.
1406 * mutex.c (__pthread_once_fork_prepare): New function.
1407 (__pthread_once_fork_child): Likewise
1408 (__pthread_once_fork_parent): Likewise
1409 (__pthread_reset_pthread_once): Removed.

1419 * join.c (pthread_exit): main thread now calls exit() instead
1420 of _exit() in order to proper process cleanup.
1421 * manager.c (__pthread_manager): Do not terminate manager
1422 after unblocking main thread; wait for main thread's
1423 REQ_PROCESS_EXIT request instead.
1424 Also, added REQ_KICK case to handle new request; this just does
1426 * manager.c (pthread_exited): Do not terminate manager after
1427 unblocking main thread.
1428 * manager.c (__pthread_manager_sighandler): If the main thread
1429 is waiting for all other threads to die, send a REQ_KICK into
1430 the thread manager request pipe to get it to clean out the threads
1431 and unblock the main thread as soon as possible. This fixes
1432 the 2000 millisecond hang on shutdown bug.
1433 * Examples/ex7.c: New file, tests shutdown behavior when all threads
1434 including the main one call pthread_exit(), or implicitly do so.
1435 * Makefile (tests): Add ex7.
1437 2000-05-05 Andreas Jaeger <aj@suse.de>

1454 * join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
1455 for eventmask larger than 1 word.
1457 2000-04-27 Ulrich Drepper <drepper@redhat.com>
1459 * Versions [libpthread] (GLIBC_2.2): Add __pthread_initialize_minimal.

1461 minimal initialization.
1462 (pthread_initialize): Remove this code here.
1463 * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again. We
1464 are working around the problem in glibc.
1466 2000-04-25 Ulrich Drepper <drepper@redhat.com>
1468 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
1469 now. First gcc must be fixed (more concrete: libgcc).
1471 2000-04-24 Ulrich Drepper <drepper@redhat.com>
1473 * pthread.c: Remove special treatement for interrupt handlers on x86.
1474 * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.
1475 * sysdeps/i386/useldt.h: Use "q" constraint instead of "r" where

1481 * join.c (pthread_exit): Set p_terminated after reporting the
1482 termination event instead of before.

1510 * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
1511 (pthread_getcpuclockid): Don't compare thread_id with thread_self,
1512 use thread_handle().
1514 2000-04-16 Ulrich Drepper <drepper@redhat.com>
1516 * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
1517 if fast mutex is used. Don't initialize `already_canceled' twice.
1518 Correctly test for return value of timedsuspend.
1520 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
1521 therefore don't need the _rt versions of the signal handlers.
1523 2000-04-15 Ulrich Drepper <drepper@redhat.com>
1525 * pthread.c (pthread_yield): New function.
1526 * sysdeps/pthread/pthread.h (pthread_yield): Add prototype.

1534 to dynamically detect RT signals and avoid generating compatibility
1535 functions with old kernel.

1853 Redesigned how cancellation unblocks a thread from internal
1854 cancellation points (sem_wait, pthread_join,
1855 pthread_cond_{wait,timedwait}).
1856 Cancellation won't eat a signal in any of these functions
1857 (*required* by POSIX and Single Unix Spec!).
1858 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a

1862 that don't belong to it instead of assuming ownership of lock
1863 upon any restart; fastlock can no longer be acquired by two threads
1865 * restart.h: Restarts queue even on kernels that don't have
1866 queued real time signals (2.0, early 2.1), thanks to atomic counter,
1867 avoiding a rare race condition in pthread_cond_timedwait.

1912 new_thread_bottom. Correct handling of stack size and when the
1913 rlimit method to guard for stack growth is used.
1914 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
1915 minus one pagesize (not two).
1917 1999-12-03 Andreas Jaeger <aj@suse.de>
