101 | Bugfix to pthread_key_delete. It was iterating over the thread | |
102 | manager's linked list of threads, behind the thread manager's | |
103 | back causing a race. The fix is to have the manager iterate over | |
104 | the threads instead, using a new request type for doing so. | |
105 | * internals.h (struct pthread_request): New manager request type | |
106 | REQ_FOR_EACH_THREAD. | |
107 | * manager.c (pthread_for_each_thread): New function. | |

109 | * specific.c (struct pthread_key_delete_helper_args): New type. | |
110 | (pthread_key_delete_helper): New static function. | |
111 | (pthread_key_delete): Use the new thread manager | |
112 | REQ_FOR_EACH_THREAD function to iterate over the threads and set | |
113 | the delete key slot to a null value in each thread. | |
114 | * Examples/ex18.c: New test. | |
115 | * Makefile (tests): Add ex18. | |

336 | Memory barrier overhaul following line by line inspection. | |

351 | __pthread_alt_timedlock, __pthread_alt_unlock, __pthread_acquire): | |
352 | Memory barrier overhaul. Lots of missing memory barriers added, | |
353 | a couple needless ones removed. | |
354 | * spinlock.c (__pthread_compare_and_swap): testandset optimization | |
355 | removed, just calls __pthread_acquire, which has the new read | |
356 | barrier in it before its testandset. | |

d364e525 | 1124 | * sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add |
0d019734 UD |
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. | |

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. | |
1498 | ||
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. | |
1503 | * sysdeps/pthread/timer_routines.c: Likewise. | |
1504 | ||
1505 | * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref, | |
1506 | timer_valid): New inline functions added. | |
1507 | ||
1508 | * sysdeps/pthread/timer_gettime.c (timer_gettime): Function | |
1509 | restructured, recursive deadlock bug fixed. | |
1510 | ||
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. | |

1523 | ||
1524 | A few optimizations. Got rid of unnecessary wakeups of timer threads, | |
1525 | tightened up some critical regions and micro-optimized some list | |
1526 | manipulation code. | |
1527 | ||
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. | |
1534 | ||
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. | |
1539 | ||
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. | |
1544 | ||
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. | |

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. | |

1669 | Added missing fork time handling of global libio lock. | |
1670 | ||
1671 | * lockfile.c (__fresetlockfiles): Now also resets the list lock, | |
1672 | not just the individual stream locks. Rewritten to use new | |
1673 | iterator interface provided by libio rather than accessing | |
1674 | global variable. | |
1675 | ||
1676 | * lockfile.c (__flockfilelist, _funlockfilelist): New functions | |
1677 | which lock and unlock the stream list using the new interface | |
1678 | provied by libio. | |
1679 | * internals.h: Likewise. | |
1680 | ||
1681 | * ptfork.c (__fork): Now calls __flockfilelist before fork, | |

1684 | ||
1685 | * linuxthreads.texi: Now explains what happens to streams at | |

1715 | Bugfix: The pthread_atfork mechanism now takes care of its | |
1716 | own internal mutex at fork time. | |
1717 | ||
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. | |
c0f3519d UD |
1721 | |
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. | |

1771 | in an ancestor process. If that state was set in an ancestor, | |

1787 | * join.c (pthread_exit): main thread now calls exit() instead | |

1789 | * manager.c (__pthread_manager): Do not terminate manager | |
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 | |
1793 | nothing. | |
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. | |

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!). | |
a3bfd999 | 2226 | * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a |
1d2fc9b3 UD |
2227 | simultaneous condition variable signal (not required by POSIX |
2228 | or Single Unix Spec, but nice). | |
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 | |
2232 | simultaneously. | |
a3bfd999 | 2233 | * restart.h: Restarts queue even on kernels that don't have |
1d2fc9b3 UD |
2234 | queued real time signals (2.0, early 2.1), thanks to atomic counter, |
2235 | avoiding a rare race condition in pthread_cond_timedwait. | |
