551 2000-08-04 Ulrich Drepper <drepper@redhat.com>
553 * Makefile (tests): Add tststack. Add rule to build the program.
554 * tststack.c: New file.
556 * internals.h: Declare __pthread_max_stacksize.
557 * pthread.c (__pthread_max_stacksize): New variable.
558 (__pthread_initialize_manager): Determine __pthread_initialize_manager
559 value.
560 * manager.c (thread_segment): Return always NULL if FLOATING_STACKS.
561 (pthread_allocate_stack): Allow kernel to choose stack address if
562 FLOATING_STACKS. This also handles variable-sized stacks.
563 Always allocate stack and guardpage together. Use mprotect to
564 change guardpage access.

584 * sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add
585 load of spin lock to prime the cache before the atomic compare and
586 exchange operation (cmpxchg4). This avoids the spinning on the
587 cmpxchg4 instruction and reduces movement of the cache line back
588 and forth between the processors (explanation by Asis K. Mallick
589 from Intel). This basically makes the implementation operate the
590 same as the Linux kernel implementation.
592 * shlib-versions: Use GLIBC_2_2 for Linux/ia64.

681 Bugfixes to the variant of the code for machines with no compare
682 and swap.
684 * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Wait
685 node was not being properly enqueued, due to failing to update
686 the lock->__status field.
688 * spinlock.c (__pthread_alt_timedlock): The oldstatus variable was
689 being set inappropriately, causing the suspend function to be called

955 Timer nodes are now reference counted, and can be marked
956 as deleted. This allows for the safe release of the global mutex
957 in the middle without losing the timer being operated on.
959 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
960 member is now an enum with three values, so that an intermediate
961 state can be represented (deleted but not free for reuse yet).

984 A few optimizations. Got rid of unnecessary wakeups of timer threads,
985 tightened up some critical regions and micro-optimized some list
986 manipulation code.

989 Returns int value now to indicate whether timer was queued at head.
990 * sysdeps/pthread/posix-timer.h: Likewise.
991 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of

993 up timer thread unnecessarily.
995 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
996 inuse flag, because this requires mutex to be held. Callers updated
997 to do the check when they have the mutex.
998 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
1000 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
1001 regions: avoids making system calls while holding timer mutex, and
1002 a few computations were moved outside of the mutex as well.
1003 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
1005 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
1006 to list_unlink_ip, meaning idempotent. Pointer manipulation
1007 changed to get better better code out of gcc.
1008 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
1009 version of list_unlink added here.
1010 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
1011 function in all places: idempotent one for timers, non-idempotent
1012 one for thread nodes.
1013 * sysdeps/pthread/timer_settime: Likewise.

1052 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
1054 * sysdeps/pthread/timer_create.c: Thread matching now done on

1127 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
1129 Added missing fork time handling of global libio lock.
1131 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
1132 not just the individual stream locks. Rewritten to use new
1133 iterator interface provided by libio rather than accessing
1134 global variable.
1136 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
1137 which lock and unlock the stream list using the new interface
1138 provied by libio.
1139 * internals.h: Likewise.
1141 * ptfork.c (__fork): Now calls __flockfilelist before fork,
1142 and __funlockfilelist in the parent after the fork.
1143 Child still calls __fresetlockfiles as before.
1145 * linuxthreads.texi: Now explains what happens to streams at
1146 fork time. Also whole new section on forking and thread added.

1173 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
1175 Bugfix: The pthread_atfork mechanism now takes care of its
1176 own internal mutex at fork time.
1178 * ptfork.c (__fork): Revised so that the mutex is held across
1179 the fork operation and while the handlers are called, and so that
1180 the child resets the mutex.
1182 * linuxthreads.texi: Updated pthread_atfork documentation to make
1183 it clear that fork and pthread_atfork can't be reentered from
1184 atfork handlers, that pthread_atfork and fork are mutually atomic,
1185 and that the handlers are inherited by the child process.
1187 2000-05-24 Ulrich Drepper <drepper@redhat.com>
1189 * Makefile (libpthread-routines): Add pspinlock.
1190 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

1226 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
1228 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
1229 object state is represented with additional bits which distinguish
1230 whether that state was set up in the current process, or
1231 in an ancestor process. If that state was set in an ancestor,
1232 it means that a fork happened while thread was executing the init
1233 function. In that case, the state is reset to NEVER.
1234 * mutex.c (__pthread_once_fork_prepare): New function.
1235 (__pthread_once_fork_child): Likewise
1236 (__pthread_once_fork_parent): Likewise

1247 * join.c (pthread_exit): main thread now calls exit() instead
1248 of _exit() in order to proper process cleanup.
1249 * manager.c (__pthread_manager): Do not terminate manager
1250 after unblocking main thread; wait for main thread's
1251 REQ_PROCESS_EXIT request instead.
1252 Also, added REQ_KICK case to handle new request; this just does
1253 nothing.
1254 * manager.c (pthread_exited): Do not terminate manager after
1255 unblocking main thread.
1256 * manager.c (__pthread_manager_sighandler): If the main thread
1257 is waiting for all other threads to die, send a REQ_KICK into
1258 the thread manager request pipe to get it to clean out the threads
1259 and unblock the main thread as soon as possible. This fixes
1260 the 2000 millisecond hang on shutdown bug.
1261 * Examples/ex7.c: New file, tests shutdown behavior when all threads
1262 including the main one call pthread_exit(), or implicitly do so.
1263 * Makefile (tests): Add ex7.
1265 2000-05-05 Andreas Jaeger <aj@suse.de>

1296 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for

1301 * pthread.c: Remove special treatement for interrupt handlers on x86.
1302 * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.

1307 2000-04-24 Mark Kettenis <kettenis@gnu.org>
1309 * join.c (pthread_exit): Set p_terminated after reporting the
1310 termination event instead of before.

1340 use thread_handle().
1342 2000-04-16 Ulrich Drepper <drepper@redhat.com>
1344 * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
1345 if fast mutex is used. Don't initialize `already_canceled' twice.
1346 Correctly test for return value of timedsuspend.
1348 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
1349 therefore don't need the _rt versions of the signal handlers.
1351 2000-04-15 Ulrich Drepper <drepper@redhat.com>
1353 * pthread.c (pthread_yield): New function.

1631 2000-01-29 Ulrich Drepper <drepper@redhat.com>
1633 * condvar.c (pthread_cond_timedwait_relative_old): Get remaining time
1634 from nanosleep call so that in case we restart we only wait for the
1635 remaining time.
1636 (pthread_cond_timedwait_relative_new): Likewise.
1637 Patch by khendricks@ivey.uwo.ca (PR libc/1561).
1639 2000-01-18 Ulrich Drepper <drepper@cygnus.com>

1681 Redesigned how cancellation unblocks a thread from internal
1682 cancellation points (sem_wait, pthread_join,
1683 pthread_cond_{wait,timedwait}).
1684 Cancellation won't eat a signal in any of these functions
1685 (*required* by POSIX and Single Unix Spec!).
1686 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
1687 simultaneous condition variable signal (not required by POSIX
1688 or Single Unix Spec, but nice).
1689 * spinlock.c: __pthread_lock queues back any received restarts
1690 that don't belong to it instead of assuming ownership of lock
1691 upon any restart; fastlock can no longer be acquired by two threads
1692 simultaneously.
1693 * restart.h: Restarts queue even on kernels that don't have
1694 queued real time signals (2.0, early 2.1), thanks to atomic counter,
1695 avoiding a rare race condition in pthread_cond_timedwait.
1697 1999-12-31 Andreas Jaeger <aj@suse.de>
1699 * internals.h: Remove duplicate prototype declarations.

1705 1999-12-30 Andreas Jaeger <aj@suse.de>
1707 * sysdeps/pthread/pthread.h: Move internal functions to...

1717 beginning.
1719 * manager.c (__pthread_start): Add one more cast to prevent

1735 pwrite64, lseek64, open64, and __open64.
1736 * wrapsyscall.c: Define pread, __pread64, pread64, pwrite, __pwrite64,
1737 pwrite64, lseek64, open64, and __open64.
1739 * manager.c (pthread_allocate_stack): Correct computation of
1740 new_thread_bottom. Correct handling of stack size and when the
1741 rlimit method to guard for stack growth is used.
1742 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
1743 minus one pagesize (not two).
1745 1999-12-03 Andreas Jaeger <aj@suse.de>
1747 * Versions: Add __res_state with version GLIBC_2.2.
1749 * errno.c (__res_state): New function to return thread specific
1750 resolver state.
1752 * pthread.c (pthread_initialize): Initialize p_resp.
1753 (__pthread_reset_main_thread): Also set p_resp.
1755 * manager.c (pthread_handle_create): Initialize p_resp.
1757 * internals.h: Add thread specific resolver state.
