 208
 209 2000-02-14  Ulrich Drepper  <drepper@redhat.com>
 210
 211         * condvar.c (pthread_cond_timedwait_relative_old): Tight loop with
 212         nanosleep does not work either.  Get absolute time inside the

 215         Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
 216
 217 2000-02-13  Andreas Jaeger  <aj@suse.de>

 223

 236
 237 2000-01-31  Ulrich Drepper  <drepper@redhat.com>
 238
 239         * condvar.c (pthread_cond_timedwait_relative_old): Recompute time
 240         before every nanosleep call to account for time spent in the rest
 241         of the function.
 242         (pthread_cond_timedwait_relative_new): Likewise.
 243         Patch by khendricks@ivey.uwo.ca (PR libc/1564).

 245 2000-01-29  Ulrich Drepper  <drepper@redhat.com>
 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).

 253 2000-01-18  Ulrich Drepper  <drepper@cygnus.com>
 254

 260
 261 2000-01-16  Ulrich Drepper  <drepper@cygnus.com>
 262
 263         * rwlock.c (pthread_rwlock_unlock): Correct one more problem with
 264         preference handling.
 265         (pthread_rwlockattr_setkind_np): Allow
 266         PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP.
 267         Patches by Kaz Kylheku <kaz@ashi.footprints.net>.
 268
 269 2000-01-12  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.
 278         * rwlock.c: Implement requirements about when readers should get

 281         (PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP): New definition.
 282         * sysdeps/pthread/bits/pthreadtypes.h (struct _pthread_rwlock_t):
 283         Define this name as well.
 284         Patches by Kaz Kylheku <kaz@ashi.footprints.net>.
 285
 286 2000-01-05  Ulrich Drepper  <drepper@cygnus.com>
 287
 288         * pthread.c (__pthread_initial_thread, pthread_manager_thread):
 289         Adjust initializers for struct _pthread_descr_struct change.
 290         * internals.h (struct _pthread_descr_struct): Move new elements to
 291         the end.
 292
 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!).
 300         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
 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.
 307         * restart.h: Restarts queue even on kernels that don't have
 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
 311 1999-12-31  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
 319 1999-12-30  Andreas Jaeger  <aj@suse.de>
 320
 321         * sysdeps/pthread/pthread.h: Move internal functions to...
 322         * sysdeps/pthread/bits/libc-lock.h: ...here.
 323

 340
 341 1999-12-20  Andreas Jaeger  <aj@suse.de>
 342
 343         * pthread.c (pthread_initialize): Move getrlimit call after

 349         pwrite64, lseek64, open64, and __open64.
 350         * wrapsyscall.c: Define pread, __pread64, pread64, pwrite, __pwrite64,
 351         pwrite64, lseek64, open64, and __open64.
 352
 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).

 360
 361         * Versions: Add __res_state with version GLIBC_2.2.

 364         resolver state.
 365
 366         * pthread.c (pthread_initialize): Initialize p_resp.
 367         (__pthread_reset_main_thread): Also set p_resp.
 368

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.
