1d2fc9b3 UD |
293 | 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net> |
294 | ||
295 | Redesigned how cancellation unblocks a thread from internal | |
296 | cancellation points (sem_wait, pthread_join, | |
297 | pthread_cond_{wait,timedwait}). | |
298 | Cancellation won't eat a signal in any of these functions | |
299 | (*required* by POSIX and Single Unix Spec!). | |
a3bfd999 | 300 | * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a |
1d2fc9b3 UD |
301 | simultaneous condition variable signal (not required by POSIX |
302 | or Single Unix Spec, but nice). | |
303 | * spinlock.c: __pthread_lock queues back any received restarts | |
304 | that don't belong to it instead of assuming ownership of lock | |
305 | upon any restart; fastlock can no longer be acquired by two threads | |
306 | simultaneously. | |
a3bfd999 | 307 | * restart.h: Restarts queue even on kernels that don't have |
1d2fc9b3 UD |
308 | queued real time signals (2.0, early 2.1), thanks to atomic counter, |
309 | avoiding a rare race condition in pthread_cond_timedwait. | |

1523 | ||
1524 | * queue.h (enqueue): Enqueue thread according to priority. | |
1525 | ||
1526 | * internals.c (struct pthread_start_args): New struct for passing | |
1527 | args to cloning function. | |
1528 | (struct _pthread): Rename to _pthread_descr_struct and adapt for | |
1529 | opaque pthread_t. | |
1530 | ||
1531 | * Examples/Makefile (clean): Pass -f option to rm. | |
1532 | ||
1533 | * sysdeps/i386/pt-machine.h: Add check for compare-exchange instruction | |
1534 | and define TEST_FOR_COMPARE_AND_SWAP. | |

1548 | __libc_getspecific, __libc_setspecific, and __libc_key_t. | |
1549 | * sysdeps/pthread/stdio-lock.h: Don't care for implementation not | |
1550 | using libio. | |

1571 | Since sigset_t no longer fits in a register, we can't pass in the | |
1572 | thread's initial mask so easily. Take this opportunity to simplify | |
1573 | the clone implementation by only accepting a single void* argument. | |
1574 | ||
1575 | * linuxthreads/manager.c (__pthread_manager): Put thread vitals | |
1576 | in the thread struct instead of as arguments through clone. | |
1577 | (pthread_start_thread): Look for them there. | |
1578 | * linuxthreads/internals.h (struct _pthread): Add p_initial_fn, | |
1579 | p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto. | |
1580 | * linuxthreads/pthread.c (pthread_initialize_manager): Revise | |
1581 | clone invocation. |
