3 * condvar.c (pthread_cond_timedwait_relative_old): Do tight
4 loop around nanosleep calls instead of around most of the function

6 body. Got rid of backwards goto and one local.
8 2000-01-31 Ulrich Drepper <drepper@redhat.com>
10 * condvar.c (pthread_cond_timedwait_relative_old): Recompute time
11 before every nanosleep call to account for time spent in the rest

27 correctly. Patch by HJ Lu.
29 * sysdeps/pthread/pthread.h: Define

38 Patches by Kaz Kylheku <kaz@ashi.footprints.net>.
40 2000-01-12 Ulrich Drepper <drepper@cygnus.com>
42 * internals.h (pthread_readlock_info): New structure.
43 (_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and

66 Redesigned how cancellation unblocks a thread from internal
67 cancellation points (sem_wait, pthread_join,
68 pthread_cond_{wait,timedwait}).
69 Cancellation won't eat a signal in any of these functions
70 (*required* by POSIX and Single Unix Spec!).
71 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
72 simultaneous condition variable signal (not required by POSIX
73 or Single Unix Spec, but nice).
74 * spinlock.c: __pthread_lock queues back any received restarts
75 that don't belong to it instead of assuming ownership of lock
76 upon any restart; fastlock can no longer be acquired by two threads
78 * restart.h: Restarts queue even on kernels that don't have
79 queued real time signals (2.0, early 2.1), thanks to atomic counter,
80 avoiding a rare race condition in pthread_cond_timedwait.

125 new_thread_bottom. Correct handling of stack size and when the
126 rlimit method to guard for stack growth is used.
127 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
128 minus one pagesize (not two).
130 1999-12-03 Andreas Jaeger <aj@suse.de>
132 * Versions: Add __res_state with version GLIBC_2.2.
