109 | Memory barrier overhaul following line by line inspection. | |
110 | * mutex.c (pthread_once): Missing memory barriers added. | |
111 | * pthread.c (__pthread_wait_for_restart_signal, | |
112 | __pthread_timedsuspend_new, __pthread_restart_new): Added | |
113 | memory barriers ``just in case'' and for documentary value. | |
114 | * spinlock.c (__pthread_release): New inline function for releasing | |
115 | spinlock, to complement __pthread_acquire. Includes memory | |
116 | barrier prior to assignment to spinlock, and __asm __volatile | |
117 | dance to prevent reordering or optimization of the spinlock access. | |
118 | * spinlock.c (__pthread_unlock, __pthread_alt_lock, | |
119 | __pthread_alt_timedlock, __pthread_alt_unlock, | |
120 | __pthread_compare_and_swap): Updated to use new __pthread_release | |
121 | instead of updating spinlock directly. | |
122 | * spinlock.c (__pthread_lock, __pthread_unlock, wait_node_alloc, | |
123 | wait_node_free, wait_node_dequeue, __pthread_alt_lock, | |
124 | __pthread_alt_timedlock, __pthread_alt_unlock, __pthread_acquire): | |
125 | Memory barrier overhaul. Lots of missing memory barriers added, | |
126 | a couple needless ones removed. | |
127 | * spinlock.c (__pthread_compare_and_swap): testandset optimization | |
128 | removed, just calls __pthread_acquire, which has the new read | |
129 | barrier in it before its testandset. | |

1268 | Timer nodes are now reference counted, and can be marked | |
1269 | as deleted. This allows for the safe release of the global mutex | |
1270 | in the middle without losing the timer being operated on. | |
1271 | ||
1272 | * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse | |
1273 | member is now an enum with three values, so that an intermediate | |
1274 | state can be represented (deleted but not free for reuse yet). | |
1275 | New refcount member added. | |
1276 | * sysdeps/pthread/timer_routines.c: Likewise. | |

1282 | restructured, recursive deadlock bug fixed. | |
1283 | ||
1284 | * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new | |
1285 | timer_addref to ensure that timer won't be deleted while mutex is not | |
1286 | held. Also uses timer_invalid to perform validation of timer handle. | |

1296 | ||
1297 | A few optimizations. Got rid of unnecessary wakeups of timer threads, | |
1298 | tightened up some critical regions and micro-optimized some list | |
1299 | manipulation code. | |
1300 | ||
1301 | * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer): | |
1302 | Returns int value now to indicate whether timer was queued at head. | |
1303 | * sysdeps/pthread/posix-timer.h: Likewise. | |
1304 | * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of | |
1305 | new return value from __timer_thread_queue_timer to avoid waking | |
1306 | up timer thread unnecessarily. | |
1307 | ||
1308 | * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks | |
1309 | inuse flag, because this requires mutex to be held. Callers updated | |
1310 | to do the check when they have the mutex. | |
1311 | * sysdeps/pthread/timer_getoverr.c: Add check for inuse here. | |
1312 | ||
1313 | * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical | |
1314 | regions: avoids making system calls while holding timer mutex, and | |
1315 | a few computations were moved outside of the mutex as well. | |
1316 | * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise. | |
1317 | ||
1318 | * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed | |
1319 | to list_unlink_ip, meaning idempotent. Pointer manipulation | |
1320 | changed to get better better code out of gcc. | |
1321 | * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent | |
1322 | version of list_unlink added here. | |
1323 | * sysdeps/pthread/timer_delete.c: Use appropriate list unlink | |
1324 | function in all places: idempotent one for timers, non-idempotent | |
1325 | one for thread nodes. | |
1326 | * sysdeps/pthread/timer_settime: Likewise. | |

1370 | different clock types. | |

1443 | ||
1444 | * lockfile.c (__fresetlockfiles): Now also resets the list lock, | |

1447 | global variable. | |

1488 | Bugfix: The pthread_atfork mechanism now takes care of its | |
1489 | own internal mutex at fork time. | |
1490 | ||
1491 | * ptfork.c (__fork): Revised so that the mutex is held across | |
1492 | the fork operation and while the handlers are called, and so that | |
1493 | the child resets the mutex. | |
c0f3519d UD |
1494 | |
1495 | * linuxthreads.texi: Updated pthread_atfork documentation to make | |
1496 | it clear that fork and pthread_atfork can't be reentered from | |
1497 | atfork handlers, that pthread_atfork and fork are mutually atomic, | |
1498 | and that the handlers are inherited by the child process. | |

1541 | * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t | |
1542 | object state is represented with additional bits which distinguish | |
1543 | whether that state was set up in the current process, or | |
1544 | in an ancestor process. If that state was set in an ancestor, | |
1545 | it means that a fork happened while thread was executing the init | |

1559 | * internals.h: New thread manager request type, REQ_KICK. | |
1560 | * join.c (pthread_exit): main thread now calls exit() instead | |
1561 | of _exit() in order to proper process cleanup. | |
1562 | * manager.c (__pthread_manager): Do not terminate manager | |
1563 | after unblocking main thread; wait for main thread's | |
1564 | REQ_PROCESS_EXIT request instead. | |
1565 | Also, added REQ_KICK case to handle new request; this just does | |
1566 | nothing. | |
1567 | * manager.c (pthread_exited): Do not terminate manager after | |
1568 | unblocking main thread. | |
1569 | * manager.c (__pthread_manager_sighandler): If the main thread | |
1570 | is waiting for all other threads to die, send a REQ_KICK into | |
1571 | the thread manager request pipe to get it to clean out the threads | |
1572 | and unblock the main thread as soon as possible. This fixes | |
1573 | the 2000 millisecond hang on shutdown bug. | |
1574 | * Examples/ex7.c: New file, tests shutdown behavior when all threads | |
1575 | including the main one call pthread_exit(), or implicitly do so. | |
1576 | * Makefile (tests): Add ex7. | |

2004 | upon any restart; fastlock can no longer be acquired by two threads | |
2005 | simultaneously. | |
