  41         * semaphore.h (SEM_FAILED): Use 0 not NULL.
  42
  43 2000-02-14  Ulrich Drepper  <drepper@redhat.com>
  44
  45         * condvar.c (pthread_cond_timedwait_relative_old): Tight loop with
  46         nanosleep does not work either.  Get absolute time inside the

  48         (pthread_cond_timedwait_relative_new): Likewise.
  49         Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
  50
  51 2000-02-13  Andreas Jaeger  <aj@suse.de>
  52

  57
  58         * condvar.c (pthread_cond_timedwait_relative_old): Undo last patch

  62         (PR libc/1597 and libc/1598).
  63
  64 2000-02-01  Kaz Kylheku  <kaz@ashi.footprints.net>
  65
  66         * condvar.c (pthread_cond_timedwait_relative_old): Do tight
  67         loop around nanosleep calls instead of around most of the function
  68         (pthread_cond_timedwait_relative_new): Likewise.
  69         body.  Got rid of backwards goto and one local.
  70
  71 2000-01-31  Ulrich Drepper  <drepper@redhat.com>
  72
  73         * condvar.c (pthread_cond_timedwait_relative_old): Recompute time
  74         before every nanosleep call to account for time spent in the rest
  75         of the function.
  76         (pthread_cond_timedwait_relative_new): Likewise.
  77         Patch by khendricks@ivey.uwo.ca (PR libc/1564).
  78
  79 2000-01-29  Ulrich Drepper  <drepper@redhat.com>
  80
  81         * condvar.c (pthread_cond_timedwait_relative_old): Get remaining time
  82         from nanosleep call so that in case we restart we only wait for the
  83         remaining time.
  84         (pthread_cond_timedwait_relative_new): Likewise.
  85         Patch by khendricks@ivey.uwo.ca (PR libc/1561).
  86
  87 2000-01-18  Ulrich Drepper  <drepper@cygnus.com>
  88
  89         * manager.c (pthread_allocate_stack): Compute guard page address

  93         PTHREAD_RWLOCK_WRITER_NONRECURSIVE_INITIALIZER_NP.
  94
  95 2000-01-16  Ulrich Drepper  <drepper@cygnus.com>
  96
  97         * rwlock.c (pthread_rwlock_unlock): Correct one more problem with
  98         preference handling.
  99         (pthread_rwlockattr_setkind_np): Allow
 100         PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP.
 101         Patches by Kaz Kylheku <kaz@ashi.footprints.net>.
 102
 103 2000-01-12  Ulrich Drepper  <drepper@cygnus.com>
 104
 105         * internals.h (pthread_readlock_info): New structure.
 106         (_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and
 107         p_untracked_readlock_count.
 108         * pthread.c (__pthread_initial_thread, pthread_manager_thread):
 109         Add initializers for new fields.
 110         * manager.c (pthread_free): Free read/write lock lists.
 111         * queue.h (queue_is_empty): New function.
 112         * rwlock.c: Implement requirements about when readers should get
 113         locks assigned.

 115         (PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP): New definition.
 116         * sysdeps/pthread/bits/pthreadtypes.h (struct _pthread_rwlock_t):
 117         Define this name as well.
 118         Patches by Kaz Kylheku <kaz@ashi.footprints.net>.
 119
 120 2000-01-05  Ulrich Drepper  <drepper@cygnus.com>
 121
 122         * pthread.c (__pthread_initial_thread, pthread_manager_thread):
 123         Adjust initializers for struct _pthread_descr_struct change.
 124         * internals.h (struct _pthread_descr_struct): Move new elements to
 125         the end.
 126
 127 2000-01-03  Kaz Kylheku  <kaz@ashi.footprints.net>
 128
 129         Redesigned how cancellation unblocks a thread from internal
 130         cancellation points (sem_wait, pthread_join,
 131         pthread_cond_{wait,timedwait}).
 132         Cancellation won't eat a signal in any of these functions
 133         (*required* by POSIX and Single Unix Spec!).
 134         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
 135         simultaneous condition variable signal (not required by POSIX
 136         or Single Unix Spec, but nice).
 137         * spinlock.c: __pthread_lock queues back any received restarts
 138         that don't belong to it instead of assuming ownership of lock
 139         upon any restart; fastlock can no longer be acquired by two threads
 140         simultaneously.
 141         * restart.h: Restarts queue even on kernels that don't have
 142         queued real time signals (2.0, early 2.1), thanks to atomic counter,
 143         avoiding a rare race condition in pthread_cond_timedwait.
 144
 145 1999-12-31  Andreas Jaeger  <aj@suse.de>
 146
 147         * internals.h: Remove duplicate prototype declarations.
 148
 149         * weaks.c: Remove __THROW from prototypes since the file is not
 150         compiled by a C++ compiler.
 151         * internals.h: Likewise.
 152
 153 1999-12-30  Andreas Jaeger  <aj@suse.de>
 154
 155         * sysdeps/pthread/pthread.h: Move internal functions to...
 156         * sysdeps/pthread/bits/libc-lock.h: ...here.
 157
 158 1999-12-29  Andreas Jaeger  <aj@suse.de>
 159
 160         * sysdeps/pthread/pthread.h: Fix typos, reformat comments.

 162 1999-12-28  Ulrich Drepper  <drepper@cygnus.com>

 165         beginning.
 166
 167         * manager.c (__pthread_start): Add one more cast to prevent
 168         warning on 64bit machines.
 169
 170 1999-12-21  Ulrich Drepper  <drepper@cygnus.com>
 171
 172         * manager.c (pthread_handle_create): Set p_pid of new thread
 173         before calling the callback function to report a new thread.
 174
 175 1999-12-20  Andreas Jaeger  <aj@suse.de>
 176
 177         * pthread.c (pthread_initialize): Move getrlimit call after
 178         setting of errno.
 179
 180 1999-12-18  Ulrich Drepper  <drepper@cygnus.com>
 181
 182         * Versions: Export pread, __pread64, pread64, pwrite, __pwrite64,
 183         pwrite64, lseek64, open64, and __open64.
 184         * wrapsyscall.c: Define pread, __pread64, pread64, pwrite, __pwrite64,
 185         pwrite64, lseek64, open64, and __open64.
 186
 187         * manager.c (pthread_allocate_stack): Correct computation of
 188         new_thread_bottom.  Correct handling of stack size and when the
 189         rlimit method to guard for stack growth is used.
 190         * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
 191         minus one pagesize (not two).
 192
 193 1999-12-03  Andreas Jaeger  <aj@suse.de>
 194
 195         * Versions: Add __res_state with version GLIBC_2.2.
 196
 197         * errno.c (__res_state): New function to return thread specific
 198         resolver state.
 199
 200         * pthread.c (pthread_initialize): Initialize p_resp.
 201         (__pthread_reset_main_thread): Also set p_resp.

 258

 275 1999-10-21  Xavier Leroy  <Xavier.Leroy@inria.fr>
 276
 277         * linuxthreads/pthread.c: For i386, wrap pthread_handle_sigrestart
 278         and pthread_handle_sigcancel with functions that restore
 279         %gs from the signal context.  For each signal handling function,
 280         two wrappers are required, one for a non-RT signal and one for
 281         a RT signal.
 282         * linuxthreads/signal.c: For i386, add code to restore %gs

 310         manager.c; include semaphore.h for needed types.
 311
 312 1999-10-08  Ulrich Drepper  <drepper@cygnus.com>
 313
 314         * manager.c (__pthread_manager) [REQ_POST]: Use __new_sem_post
 315         directly instead of calling sem_post which should not be necessary
 316         but is faster and might help in some case to work around problems.
 317         Patch by khendricks@ivey.uwo.ca [libc/1382].
 318
 319 1999-10-08  Andreas Schwab  <schwab@suse.de>

 340 1999-09-19  Ulrich Drepper  <drepper@cygnus.com>
 341
 342         * signals.c (sigaction): Correct last patch.  Don't select
 343         pthread_sighandler_rt based on the signal number but instead of
 344         the SA_SIGINFO flag.
 345
 346 1999-09-23  Ulrich Drepper  <drepper@cygnus.com>
 347
 348         * specific.c: Move definitions of struct pthread_key_struct and

 353
 354         * pthread.c (pthread_handle_sigrestart_rt): New function.  Use

 356         signal.
 357
 358         * signals.c: Handle passing through of sighandler arguments also
 359         for real-time signals.
 360
 361 1999-09-03  Andreas Schwab  <schwab@suse.de>
 362
 363         * ptfork.c (__fork): Renamed from fork and use __libc_fork.  Add

 374
 375         * pthread.c (__pthread_reset_main_thread): Undo last change.
