246
247 * condvar.c (pthread_cond_timedwait_relative_old): Get remaining time
248 from nanosleep call so that in case we restart we only wait for the
249 remaining time.
250 (pthread_cond_timedwait_relative_new): Likewise.
251 Patch by khendricks@ivey.uwo.ca (PR libc/1561).

UD		 2692000-01-12 Ulrich Drepper <drepper@cygnus.com>
270
271 * internals.h (pthread_readlock_info): New structure.
272 (_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and
273 p_untracked_readlock_count.
274 * pthread.c (__pthread_initial_thread, pthread_manager_thread):
275 Add initializers for new fields.
276 * manager.c (pthread_free): Free read/write lock lists.
277 * queue.h (queue_is_empty): New function.

292
1d2fc9b3
UD		 2932000-01-03 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.
310
1c5d4617
UD		 3111999-12-31 Andreas Jaeger <aj@suse.de>
312
313 * internals.h: Remove duplicate prototype declarations.
314
315 * weaks.c: Remove __THROW from prototypes since the file is not
316 compiled by a C++ compiler.
317 * internals.h: Likewise.
318
3191999-12-30 Andreas Jaeger <aj@suse.de>
320
321 * sysdeps/pthread/pthread.h: Move internal functions to...
322 * sysdeps/pthread/bits/libc-lock.h: ...here.

333 * manager.c (__pthread_start): Add one more cast to prevent
334 warning on 64bit machines.
335
46fd4f67

351 pwrite64, lseek64, open64, and __open64.
352
b85697f6
UD		 353 * manager.c (pthread_allocate_stack): Correct computation of
354 new_thread_bottom. Correct handling of stack size and when the
355 rlimit method to guard for stack growth is used.
356 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
357 minus one pagesize (not two).
358
