  21         Be prepared for empty timer list.
  22
  23         * sysdeps/pthread/timer_create.c (timer_create): Correct names of
  24         CPUTIME clock ID.  Add support for thread clocks.

  61
  62         Added missing fork time handling of global libio lock.
  63
  64         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
  65         not just the individual stream locks. Rewritten to use new
  66         iterator interface provided by libio rather than accessing
  67         global variable.
  68
  69         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
  70         which lock and unlock the stream list using the new interface
  71         provied by libio.
  72         * internals.h: Likewise.
  73
  74         * ptfork.c (__fork): Now calls __flockfilelist before fork,
  75         and __funlockfilelist in the parent after the fork.
  76         Child still calls __fresetlockfiles as before.
  77
  78         * linuxthreads.texi: Now explains what happens to streams at
  79         fork time. Also whole new section on forking and thread added.
  80         Definition of pthread_atfork moved out of Miscellaneous Functions
  81         to this new section.
  82
  83 2000-06-04  Jakub Jelinek  <jakub@redhat.com>

  98
  99 2000-05-28  Ulrich Drepper  <drepper@redhat.com>
 100
 101         * spinlock.c (__pthread_lock): Remove ASSERT.
 102
 103         * Makefile (tests): Add ex8.

 105
 106 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
 107
 108         Bugfix: The pthread_atfork mechanism now takes care of its
 109         own internal mutex at fork time.
 110
 111         * ptfork.c (__fork): Revised so that the mutex is held across
 112         the fork operation and while the handlers are called, and so that
 113         the child resets the mutex.
 114
 115         * linuxthreads.texi: Updated pthread_atfork documentation to make
 116         it clear that fork and pthread_atfork can't be reentered from
 117         atfork handlers, that pthread_atfork and fork are mutually atomic,
 118         and that the handlers are inherited by the child process.
 119
 120 2000-05-24  Ulrich Drepper  <drepper@redhat.com>
 121
 122         * Makefile (libpthread-routines): Add pspinlock.
 123         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

 145         back to _pthread_fastlock.  Define new pthread_spinlock_t.
 146
 147 2000-05-24  Andreas Jaeger  <aj@suse.de>
 148
 149         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.
 150
 151 2000-05-21  Jakub Jelinek  <jakub@redhat.com>
 152
 153         * manager.c (pthread_handle_create): Initialize p_res._sock to -1.
 154
 155 2000-05-13  Jakub Jelinek  <jakub@redhat.com>
 156
 157         * internals.h (__RES_PTHREAD_INTERNAL): Define.
 158
 159 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
 160
 161         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
 162         object state is represented with additional bits which distinguish
 163         whether that state was set up in the current process, or
 164         in an ancestor process. If that state was set in an ancestor,
 165         it means that a fork happened while thread was executing the init
 166         function. In that case, the state is reset to NEVER.
 167         * mutex.c (__pthread_once_fork_prepare): New function.
 168         (__pthread_once_fork_child): Likewise
 169         (__pthread_once_fork_parent): Likewise
 170         (__pthread_reset_pthread_once): Removed.
 171         * ptfork.c (__fork): Call new handlers in mutex.c.
 172         * internals.h: Declarations of new mutex.c functions added.
 173         Declaration of removed function deleted.
 174         * linuxthreads.texi: Updated documentation about pthread_once
 175         to clarify what happens under cancellation and forking.
 176
 177 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
 178
 179         * internals.h: New thread manager request type, REQ_KICK.
 180         * join.c (pthread_exit): main thread now calls exit() instead
 181         of _exit() in order to proper process cleanup.
 182         * manager.c (__pthread_manager): Do not terminate manager
 183         after unblocking main thread; wait for main thread's
 184         REQ_PROCESS_EXIT request instead.
 185         Also, added REQ_KICK case to handle new request; this just does
 186         nothing.
 187         * manager.c (pthread_exited): Do not terminate manager after
 188         unblocking main thread.
 189         * manager.c (__pthread_manager_sighandler): If the main thread
 190         is waiting for all other threads to die, send a REQ_KICK into
 191         the thread manager request pipe to get it to clean out the threads
 192         and unblock the main thread as soon as possible. This fixes
 193         the 2000 millisecond hang on shutdown bug.
 194         * Examples/ex7.c: New file, tests shutdown behavior when all threads
 195         including the main one call pthread_exit(), or implicitly do so.
 196         * Makefile (tests): Add ex7.
 197
 198 2000-05-05  Andreas Jaeger  <aj@suse.de>
 199
 200         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
 201         (pthread_getcpuclockid): Correct test for ourselves.
 202
 203 2000-05-05  Ulrich Drepper  <drepper@redhat.com>
 204
 205         * internals.h (struct _pthread_descr_struct): Reorganization.
 206         Allocate room for 16 pointers at head of the structure for future
 207         thread-local data handling.  Move p_self member in this area.
 208         * manager.c (pthread_handle_create): Adjust use of p_self.
 209         * sysdeps/i386/useldt.h (THREAD_SELF): Likewise.
 210         * pthread.c (__pthread_initial_thread): Adjust initialization.
 211         (__pthread_manager_thread): Likewise.

 214
 215         * join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
 216         for eventmask larger than 1 word.

 220         * Versions [libpthread] (GLIBC_2.2): Add __pthread_initialize_minimal.
 221         * pthread.c (__pthread_initialize_minimal): New function.  Perform
 222         minimal initialization.
 223         (pthread_initialize): Remove this code here.
 224         * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again.  We
 225         are working around the problem in glibc.
 226
 227 2000-04-25  Ulrich Drepper  <drepper@redhat.com>
 228
 229         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
 230         now.  First gcc must be fixed (more concrete: libgcc).
 231
 232 2000-04-24  Ulrich Drepper  <drepper@redhat.com>
 233
 234         * pthread.c: Remove special treatement for interrupt handlers on x86.
 235         * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.
 236         * sysdeps/i386/useldt.h: Use "q" constraint instead of "r" where
 237         necessary.
 238         * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h".
 239
 240 2000-04-24  Mark Kettenis  <kettenis@gnu.org>
 241
 242         * join.c (pthread_exit): Set p_terminated after reporting the
 243         termination event instead of before.
 244
 245 2000-04-20  Jakub Jelinek  <jakub@redhat.com>
 246
 247         * sysdeps/pthread/bits/libc-lock.h: Only declare __pthread_rwlock_*
 248         if __USE_UNIX98.
 249
 250 2000-04-18  Andreas Jaeger  <aj@suse.de>
 251

 253
 254 2000-04-18  Jakub Jelinek  <jakub@redhat.com>
 255

 272         (pthread_getcpuclockid): Don't compare thread_id with thread_self,
 273         use thread_handle().
 274
 275 2000-04-16  Ulrich Drepper  <drepper@redhat.com>
 276
 277         * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
 278         if fast mutex is used.  Don't initialize `already_canceled' twice.
 279         Correctly test for return value of timedsuspend.
 280
 281         * pthread.c: Correct long-time braino.  We never set SA_SIGINFO and
 282         therefore don't need the _rt versions of the signal handlers.
 283
 284 2000-04-15  Ulrich Drepper  <drepper@redhat.com>

 292         realtime signals are known to exist.
 293
 294         * pthread.c: Is __ASSUME_REALTIME_SIGNALS then avoid generating code
 295         to dynamically detect RT signals and avoid generating compatibility
 296         functions with old kernel.
 297         * restart.h (restart) [__ASSUME_REALTIME_SIGNALS]: Use
 298         __pthread_restart_new directly.
 299         (suspend) [__ASSUME_REALTIME_SIGNALS]: Use
 300         __pthread_wait_for_restart_signal directly.

 317         suspension function through __pthread_timedsuspend.
 318         * semaphore.c (sem_timedwait): Use timedsuspend, don't duplicate
 319         the code.
 320         Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
 321
 322         * internals.h (WRITE_MEMORY_BARRIER): Define as MEMORY_BARRIER if
 323         undefined.

 614         Redesigned how cancellation unblocks a thread from internal
 615         cancellation points (sem_wait, pthread_join,
 616         pthread_cond_{wait,timedwait}).
 617         Cancellation won't eat a signal in any of these functions
 618         (*required* by POSIX and Single Unix Spec!).
 619         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
 620         simultaneous condition variable signal (not required by POSIX
 621         or Single Unix Spec, but nice).
 622         * spinlock.c: __pthread_lock queues back any received restarts
 623         that don't belong to it instead of assuming ownership of lock
 624         upon any restart; fastlock can no longer be acquired by two threads
 625         simultaneously.
 626         * restart.h: Restarts queue even on kernels that don't have
 627         queued real time signals (2.0, early 2.1), thanks to atomic counter,
 628         avoiding a rare race condition in pthread_cond_timedwait.

1890         Since sigset_t no longer fits in a register, we can't pass in the
1891         thread's initial mask so easily.  Take this opportunity to simplify
1892         the clone implementation by only accepting a single void* argument.
1893
1894         * linuxthreads/manager.c (__pthread_manager): Put thread vitals
1895         in the thread struct instead of as arguments through clone.
1896         (pthread_start_thread): Look for them there.
1897         * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
1898         p_initial_fn_arg, p_initial_mask.  Fix __pthread_manager proto.
1899         * linuxthreads/pthread.c (pthread_initialize_manager): Revise
1900         clone invocation.
