572 Bugfix to pthread_key_delete. It was iterating over the thread
573 manager's linked list of threads, behind the thread manager's

1595 * sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add
1596 load of spin lock to prime the cache before the atomic compare and
1597 exchange operation (cmpxchg4). This avoids the spinning on the
1598 cmpxchg4 instruction and reduces movement of the cache line back
1599 and forth between the processors (explanation by Asis K. Mallick
1600 from Intel). This basically makes the implementation operate the
1601 same as the Linux kernel implementation.
1603 * shlib-versions: Use GLIBC_2_2 for Linux/ia64.

1692 Bugfixes to the variant of the code for machines with no compare
1695 * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Wait
1696 node was not being properly enqueued, due to failing to update
1697 the lock->__status field.
1699 * spinlock.c (__pthread_alt_timedlock): The oldstatus variable was
1700 being set inappropriately, causing the suspend function to be called

1964 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
1966 Timer nodes are now reference counted, and can be marked
1967 as deleted. This allows for the safe release of the global mutex
1968 in the middle without losing the timer being operated on.
1970 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
1971 member is now an enum with three values, so that an intermediate
1972 state can be represented (deleted but not free for reuse yet).
1973 New refcount member added.

1983 timer_addref to ensure that timer won't be deleted while mutex is not
1984 held. Also uses timer_invalid to perform validation of timer handle.
1985 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
1986 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
1988 2000-06-14 Ulrich Drepper <drepper@redhat.com>

1999 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2000 Returns int value now to indicate whether timer was queued at head.
2001 * sysdeps/pthread/posix-timer.h: Likewise.
2002 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
2003 new return value from __timer_thread_queue_timer to avoid waking
2004 up timer thread unnecessarily.
2006 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
2007 inuse flag, because this requires mutex to be held. Callers updated
2008 to do the check when they have the mutex.
2009 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
2011 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
2012 regions: avoids making system calls while holding timer mutex, and
2013 a few computations were moved outside of the mutex as well.
2014 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
2016 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
2017 to list_unlink_ip, meaning idempotent. Pointer manipulation
2018 changed to get better better code out of gcc.
2019 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
2020 version of list_unlink added here.
2021 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
2022 function in all places: idempotent one for timers, non-idempotent
2023 one for thread nodes.
2024 * sysdeps/pthread/timer_settime: Likewise.
2025 * sysdeps/pthread/timer_routines.c: Likewise.
2027 2000-06-13 Ulrich Drepper <drepper@redhat.com>
2029 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

2061 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
2063 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
2065 * sysdeps/pthread/timer_create.c: Thread matching now done on
2066 clock type as well as thread attributes.
2067 There are individual global signal-delivering threads for
2068 different clock types.
2069 * sysdeps/pthread/posix-timer.h: Likewise.
2070 * sysdeps/pthread/timer_routines.c: Likewise.
2072 * sysdeps/pthread/timer_routines.c: Thread allocation and
2073 deallocation function now remembers to put thread on active
2074 list and remove from active list.
2075 Thus now the feature of binding multiple timers
2076 to a single thread actually works.
2078 2000-06-10 Ulrich Drepper <drepper@redhat.com>
2080 * pthread.c (__pthread_create_2_1): Optimize a bit.
2082 * internals.h (invalid_handle): Also test for p_terminated != 0.

2085 invalid_handle to test for acceptable thread handle.
2086 * manager.c (pthread_handle_free): Likewise.
2087 * joinrace.c: New file.
2088 Reported by Permaine Cheung <pcheung@cygnus.com>.
2090 2000-06-08 Ulrich Drepper <drepper@redhat.com>

2142 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
2143 not just the individual stream locks. Rewritten to use new
2144 iterator interface provided by libio rather than accessing
2147 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
2148 which lock and unlock the stream list using the new interface
2150 * internals.h: Likewise.
2152 * ptfork.c (__fork): Now calls __flockfilelist before fork,
2153 and __funlockfilelist in the parent after the fork.
2154 Child still calls __fresetlockfiles as before.
2156 * linuxthreads.texi: Now explains what happens to streams at

2184 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
2186 Bugfix: The pthread_atfork mechanism now takes care of its
2187 own internal mutex at fork time.
2189 * ptfork.c (__fork): Revised so that the mutex is held across
2190 the fork operation and while the handlers are called, and so that
2191 the child resets the mutex.
2193 * linuxthreads.texi: Updated pthread_atfork documentation to make
2194 it clear that fork and pthread_atfork can't be reentered from
2195 atfork handlers, that pthread_atfork and fork are mutually atomic,
2196 and that the handlers are inherited by the child process.
2198 2000-05-24 Ulrich Drepper <drepper@redhat.com>
2200 * Makefile (libpthread-routines): Add pspinlock.
2201 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

2237 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
2239 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
2240 object state is represented with additional bits which distinguish
2241 whether that state was set up in the current process, or
2242 in an ancestor process. If that state was set in an ancestor,
2243 it means that a fork happened while thread was executing the init
2244 function. In that case, the state is reset to NEVER.
2245 * mutex.c (__pthread_once_fork_prepare): New function.
2246 (__pthread_once_fork_child): Likewise

2261 after unblocking main thread; wait for main thread's
2262 REQ_PROCESS_EXIT request instead.
2263 Also, added REQ_KICK case to handle new request; this just does
2265 * manager.c (pthread_exited): Do not terminate manager after
2266 unblocking main thread.
2267 * manager.c (__pthread_manager_sighandler): If the main thread
2268 is waiting for all other threads to die, send a REQ_KICK into
2269 the thread manager request pipe to get it to clean out the threads
2270 and unblock the main thread as soon as possible. This fixes
2271 the 2000 millisecond hang on shutdown bug.
2272 * Examples/ex7.c: New file, tests shutdown behavior when all threads
2273 including the main one call pthread_exit(), or implicitly do so.
2274 * Makefile (tests): Add ex7.
2276 2000-05-05 Andreas Jaeger <aj@suse.de>

2307 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for

2356 if fast mutex is used. Don't initialize `already_canceled' twice.
2357 Correctly test for return value of timedsuspend.
2359 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
2360 therefore don't need the _rt versions of the signal handlers.

2692 Redesigned how cancellation unblocks a thread from internal
2693 cancellation points (sem_wait, pthread_join,
2694 pthread_cond_{wait,timedwait}).
2695 Cancellation won't eat a signal in any of these functions
2696 (*required* by POSIX and Single Unix Spec!).
2697 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
2698 simultaneous condition variable signal (not required by POSIX
2699 or Single Unix Spec, but nice).
2700 * spinlock.c: __pthread_lock queues back any received restarts
2701 that don't belong to it instead of assuming ownership of lock
2702 upon any restart; fastlock can no longer be acquired by two threads
2704 * restart.h: Restarts queue even on kernels that don't have
2705 queued real time signals (2.0, early 2.1), thanks to atomic counter,
2706 avoiding a rare race condition in pthread_cond_timedwait.
2708 1999-12-31 Andreas Jaeger <aj@suse.de>

2751 new_thread_bottom. Correct handling of stack size and when the
2752 rlimit method to guard for stack growth is used.
2753 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
2754 minus one pagesize (not two).

2840 * pthread.c: For i386, wrap pthread_handle_sigrestart and
2841 pthread_handle_sigcancel with functions that restore %gs from the
