174 | 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net> |
175 | ||
176 | Redesigned how cancellation unblocks a thread from internal | |
177 | cancellation points (sem_wait, pthread_join, | |
178 | pthread_cond_{wait,timedwait}). | |
179 | Cancellation won't eat a signal in any of these functions | |
180 | (*required* by POSIX and Single Unix Spec!). | |
a3bfd999 | 181 | * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a |
1d2fc9b3 UD |
182 | simultaneous condition variable signal (not required by POSIX |
183 | or Single Unix Spec, but nice). | |
184 | * spinlock.c: __pthread_lock queues back any received restarts | |
185 | that don't belong to it instead of assuming ownership of lock | |
186 | upon any restart; fastlock can no longer be acquired by two threads | |
187 | simultaneously. | |
a3bfd999 | 188 | * restart.h: Restarts queue even on kernels that don't have |
1d2fc9b3 UD |
189 | queued real time signals (2.0, early 2.1), thanks to atomic counter, |
190 | avoiding a rare race condition in pthread_cond_timedwait. | |

197 | compiled by a C++ compiler. | |
198 | * internals.h: Likewise. | |

234 | * manager.c (pthread_allocate_stack): Correct computation of |
235 | new_thread_bottom. Correct handling of stack size and when the | |
