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

1091 2000-08-04 Ulrich Drepper <drepper@redhat.com>
1093 * Makefile (tests): Add tststack. Add rule to build the program.
1094 * tststack.c: New file.
1096 * internals.h: Declare __pthread_max_stacksize.
1097 * pthread.c (__pthread_max_stacksize): New variable.
1098 (__pthread_initialize_manager): Determine __pthread_initialize_manager
1100 * manager.c (thread_segment): Return always NULL if FLOATING_STACKS.
1101 (pthread_allocate_stack): Allow kernel to choose stack address if
1102 FLOATING_STACKS. This also handles variable-sized stacks.
1103 Always allocate stack and guardpage together. Use mprotect to
1104 change guardpage access.
1105 * sysdeps/i386/useldt.h: Define FLOATING_STACKS and
1106 ARCH_STACK_MAX_SIZE.
1108 * attr.c (__pthread_attr_setstacksize): Also test value against

1124 * sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add
1125 load of spin lock to prime the cache before the atomic compare and
1126 exchange operation (cmpxchg4). This avoids the spinning on the
1127 cmpxchg4 instruction and reduces movement of the cache line back
1128 and forth between the processors (explanation by Asis K. Mallick
1129 from Intel). This basically makes the implementation operate the
1130 same as the Linux kernel implementation.
1132 * shlib-versions: Use GLIBC_2_2 for Linux/ia64.

1221 Bugfixes to the variant of the code for machines with no compare
1224 * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Wait
1225 node was not being properly enqueued, due to failing to update
1226 the lock->__status field.
1228 * spinlock.c (__pthread_alt_timedlock): The oldstatus variable was
1229 being set inappropriately, causing the suspend function to be called
1230 with a null self pointer and crash.

1493 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
1495 Timer nodes are now reference counted, and can be marked
1496 as deleted. This allows for the safe release of the global mutex
1497 in the middle without losing the timer being operated on.
1499 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
1500 member is now an enum with three values, so that an intermediate
1501 state can be represented (deleted but not free for reuse yet).
1502 New refcount member added.

1511 * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
1512 timer_addref to ensure that timer won't be deleted while mutex is not
1513 held. Also uses timer_invalid to perform validation of timer handle.
1514 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
1515 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
1517 2000-06-14 Ulrich Drepper <drepper@redhat.com>

1522 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
1524 A few optimizations. Got rid of unnecessary wakeups of timer threads,
1525 tightened up some critical regions and micro-optimized some list
1528 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
1529 Returns int value now to indicate whether timer was queued at head.
1530 * sysdeps/pthread/posix-timer.h: Likewise.
1531 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
1532 new return value from __timer_thread_queue_timer to avoid waking
1533 up timer thread unnecessarily.
1535 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
1536 inuse flag, because this requires mutex to be held. Callers updated
1537 to do the check when they have the mutex.
1538 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
1540 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
1541 regions: avoids making system calls while holding timer mutex, and
1542 a few computations were moved outside of the mutex as well.
1543 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
1545 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
1546 to list_unlink_ip, meaning idempotent. Pointer manipulation
1547 changed to get better better code out of gcc.
1548 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
1549 version of list_unlink added here.
1550 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
1551 function in all places: idempotent one for timers, non-idempotent
1552 one for thread nodes.
1553 * sysdeps/pthread/timer_settime: Likewise.
1554 * sysdeps/pthread/timer_routines.c: Likewise.
1556 2000-06-13 Ulrich Drepper <drepper@redhat.com>
1558 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

1590 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
1592 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
1594 * sysdeps/pthread/timer_create.c: Thread matching now done on
1595 clock type as well as thread attributes.
1596 There are individual global signal-delivering threads for
1597 different clock types.
1598 * sysdeps/pthread/posix-timer.h: Likewise.
1599 * sysdeps/pthread/timer_routines.c: Likewise.
1601 * sysdeps/pthread/timer_routines.c: Thread allocation and
1602 deallocation function now remembers to put thread on active
1603 list and remove from active list.
1604 Thus now the feature of binding multiple timers
1605 to a single thread actually works.
1607 2000-06-10 Ulrich Drepper <drepper@redhat.com>
1609 * pthread.c (__pthread_create_2_1): Optimize a bit.
1611 * internals.h (invalid_handle): Also test for p_terminated != 0.
1612 (nonexisting_handle): New function. Same as old invalid_handle.
1613 * join.c (pthread_join): Use nonexisting_handle instead of
1614 invalid_handle to test for acceptable thread handle.
1615 * manager.c (pthread_handle_free): Likewise.

1677 which lock and unlock the stream list using the new interface
1679 * internals.h: Likewise.
1681 * ptfork.c (__fork): Now calls __flockfilelist before fork,
1682 and __funlockfilelist in the parent after the fork.
1683 Child still calls __fresetlockfiles as before.

1715 Bugfix: The pthread_atfork mechanism now takes care of its
1716 own internal mutex at fork time.
1718 * ptfork.c (__fork): Revised so that the mutex is held across
1719 the fork operation and while the handlers are called, and so that
1720 the child resets the mutex.
1722 * linuxthreads.texi: Updated pthread_atfork documentation to make
1723 it clear that fork and pthread_atfork can't be reentered from
1724 atfork handlers, that pthread_atfork and fork are mutually atomic,
1725 and that the handlers are inherited by the child process.

1729 * Makefile (libpthread-routines): Add pspinlock.

1768 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
1769 object state is represented with additional bits which distinguish
1770 whether that state was set up in the current process, or
1771 in an ancestor process. If that state was set in an ancestor,
1772 it means that a fork happened while thread was executing the init
1773 function. In that case, the state is reset to NEVER.
1774 * mutex.c (__pthread_once_fork_prepare): New function.
1775 (__pthread_once_fork_child): Likewise

1790 after unblocking main thread; wait for main thread's
1791 REQ_PROCESS_EXIT request instead.
1792 Also, added REQ_KICK case to handle new request; this just does
1794 * manager.c (pthread_exited): Do not terminate manager after
1795 unblocking main thread.
1796 * manager.c (__pthread_manager_sighandler): If the main thread
1797 is waiting for all other threads to die, send a REQ_KICK into
1798 the thread manager request pipe to get it to clean out the threads
1799 and unblock the main thread as soon as possible. This fixes
1800 the 2000 millisecond hang on shutdown bug.
1801 * Examples/ex7.c: New file, tests shutdown behavior when all threads
1802 including the main one call pthread_exit(), or implicitly do so.
1803 * Makefile (tests): Add ex7.
1805 2000-05-05 Andreas Jaeger <aj@suse.de>

1885 if fast mutex is used. Don't initialize `already_canceled' twice.
1886 Correctly test for return value of timedsuspend.
1888 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
1889 therefore don't need the _rt versions of the signal handlers.

2221 Redesigned how cancellation unblocks a thread from internal
2222 cancellation points (sem_wait, pthread_join,
2223 pthread_cond_{wait,timedwait}).
2224 Cancellation won't eat a signal in any of these functions
2225 (*required* by POSIX and Single Unix Spec!).
2226 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a

2229 * spinlock.c: __pthread_lock queues back any received restarts
2230 that don't belong to it instead of assuming ownership of lock
2231 upon any restart; fastlock can no longer be acquired by two threads
2233 * restart.h: Restarts queue even on kernels that don't have
2234 queued real time signals (2.0, early 2.1), thanks to atomic counter,
2235 avoiding a rare race condition in pthread_cond_timedwait.

2280 new_thread_bottom. Correct handling of stack size and when the
2281 rlimit method to guard for stack growth is used.
2282 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
2283 minus one pagesize (not two).
