 245
 246         * condvar.c (pthread_cond_timedwait_relative_old): Tight loop with

 256
 257 2000-02-13  Ulrich Drepper  <drepper@redhat.com>

 271
 272 2000-01-31  Ulrich Drepper  <drepper@redhat.com>
 273
 274         * condvar.c (pthread_cond_timedwait_relative_old): Recompute time
 275         before every nanosleep call to account for time spent in the rest
 276         of the function.

 278         Patch by khendricks@ivey.uwo.ca (PR libc/1564).

 281
 282         * condvar.c (pthread_cond_timedwait_relative_old): Get remaining time
 283         from nanosleep call so that in case we restart we only wait for the
 284         remaining time.
 285         (pthread_cond_timedwait_relative_new): Likewise.
 286         Patch by khendricks@ivey.uwo.ca (PR libc/1561).

 301         PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP.

 303
 304 2000-01-12  Ulrich Drepper  <drepper@cygnus.com>
 305
 306         * internals.h (pthread_readlock_info): New structure.

 308         p_untracked_readlock_count.
 309         * pthread.c (__pthread_initial_thread, pthread_manager_thread):
 310         Add initializers for new fields.

 317         * sysdeps/pthread/bits/pthreadtypes.h (struct _pthread_rwlock_t):

 320
 321 2000-01-05  Ulrich Drepper  <drepper@cygnus.com>
 322
 323         * pthread.c (__pthread_initial_thread, pthread_manager_thread):

 325         * internals.h (struct _pthread_descr_struct): Move new elements to
 326         the end.
 327
 328 2000-01-03  Kaz Kylheku  <kaz@ashi.footprints.net>
 329
 330         Redesigned how cancellation unblocks a thread from internal
 331         cancellation points (sem_wait, pthread_join,
 332         pthread_cond_{wait,timedwait}).
 333         Cancellation won't eat a signal in any of these functions
 334         (*required* by POSIX and Single Unix Spec!).
 335         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
 336         simultaneous condition variable signal (not required by POSIX
 337         or Single Unix Spec, but nice).
 338         * spinlock.c: __pthread_lock queues back any received restarts
 339         that don't belong to it instead of assuming ownership of lock
 340         upon any restart; fastlock can no longer be acquired by two threads
 341         simultaneously.
 342         * restart.h: Restarts queue even on kernels that don't have
 343         queued real time signals (2.0, early 2.1), thanks to atomic counter,
 344         avoiding a rare race condition in pthread_cond_timedwait.
 345
 346 1999-12-31  Andreas Jaeger  <aj@suse.de>
 347
 348         * internals.h: Remove duplicate prototype declarations.
 349
 350         * weaks.c: Remove __THROW from prototypes since the file is not
 351         compiled by a C++ compiler.
 352         * internals.h: Likewise.
 353
 354 1999-12-30  Andreas Jaeger  <aj@suse.de>
 355
 356         * sysdeps/pthread/pthread.h: Move internal functions to...
 357         * sysdeps/pthread/bits/libc-lock.h: ...here.
 358
 359 1999-12-29  Andreas Jaeger  <aj@suse.de>
 360
 361         * sysdeps/pthread/pthread.h: Fix typos, reformat comments.

1606         Since sigset_t no longer fits in a register, we can't pass in the
1607         thread's initial mask so easily.  Take this opportunity to simplify

1613         * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
1614         p_initial_fn_arg, p_initial_mask.  Fix __pthread_manager proto.
1615         * linuxthreads/pthread.c (pthread_initialize_manager): Revise
1616         clone invocation.
