  25
  26         Bugfix: The pthread_atfork mechanism now takes care of its
  27         own internal mutex at fork time.
  28
  29         * ptfork.c (__fork): Revised so that the mutex is held across
  30         the fork operation and while the handlers are called, and so that
  31         the child resets the mutex.
  32
  33         * linuxthreads.texi: Updated pthread_atfork documentation to make
  34         it clear that fork and pthread_atfork can't be reentered from
  35         atfork handlers, that pthread_atfork and fork are mutually atomic,
  36         and that the handlers are inherited by the child process.
  37

  39
  40         * Makefile (libpthread-routines): Add pspinlock.
  41         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

  64
  65 2000-05-24  Andreas Jaeger  <aj@suse.de>
  66
  67         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.
  68

  72
  73 2000-05-13  Jakub Jelinek  <jakub@redhat.com>
  74
  75         * internals.h (__RES_PTHREAD_INTERNAL): Define.
  76
  77 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
  78
  79         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
  80         object state is represented with additional bits which distinguish
  81         whether that state was set up in the current process, or
  82         in an ancestor process. If that state was set in an ancestor,
  83         it means that a fork happened while thread was executing the init
  84         function. In that case, the state is reset to NEVER.
  85         * mutex.c (__pthread_once_fork_prepare): New function.
  86         (__pthread_once_fork_child): Likewise
  87         (__pthread_once_fork_parent): Likewise
  88         (__pthread_reset_pthread_once): Removed.
  89         * ptfork.c (__fork): Call new handlers in mutex.c.
  90         * internals.h: Declarations of new mutex.c functions added.
  91         Declaration of removed function deleted.
  92         * linuxthreads.texi: Updated documentation about pthread_once
  93         to clarify what happens under cancellation and forking.
  94
  95 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
  96
  97         * internals.h: New thread manager request type, REQ_KICK.
  98         * join.c (pthread_exit): main thread now calls exit() instead
  99         of _exit() in order to proper process cleanup.
 100         * manager.c (__pthread_manager): Do not terminate manager
 101         after unblocking main thread; wait for main thread's
 102         REQ_PROCESS_EXIT request instead.
 103         Also, added REQ_KICK case to handle new request; this just does
 104         nothing.
 105         * manager.c (pthread_exited): Do not terminate manager after
 106         unblocking main thread.
 107         * manager.c (__pthread_manager_sighandler): If the main thread
 108         is waiting for all other threads to die, send a REQ_KICK into
 109         the thread manager request pipe to get it to clean out the threads
 110         and unblock the main thread as soon as possible. This fixes
 111         the 2000 millisecond hang on shutdown bug.
 112         * Examples/ex7.c: New file, tests shutdown behavior when all threads
 113         including the main one call pthread_exit(), or implicitly do so.
 114         * Makefile (tests): Add ex7.
 115
 116 2000-05-05  Andreas Jaeger  <aj@suse.de>
 117
 118         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
 119         (pthread_getcpuclockid): Correct test for ourselves.
 120
 121 2000-05-05  Ulrich Drepper  <drepper@redhat.com>
 122
 123         * internals.h (struct _pthread_descr_struct): Reorganization.
 124         Allocate room for 16 pointers at head of the structure for future
 125         thread-local data handling.  Move p_self member in this area.
 126         * manager.c (pthread_handle_create): Adjust use of p_self.
 127         * sysdeps/i386/useldt.h (THREAD_SELF): Likewise.
 128         * pthread.c (__pthread_initial_thread): Adjust initialization.
 129         (__pthread_manager_thread): Likewise.

 131 2000-04-29  Bruno Haible  <haible@clisp.cons.org>
 132
 133         * join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
 134         for eventmask larger than 1 word.
 135
 136 2000-04-27  Ulrich Drepper  <drepper@redhat.com>

 138         * Versions [libpthread] (GLIBC_2.2): Add __pthread_initialize_minimal.
 139         * pthread.c (__pthread_initialize_minimal): New function.  Perform
 140         minimal initialization.
 141         (pthread_initialize): Remove this code here.
 142         * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again.  We
 143         are working around the problem in glibc.
 144
 145 2000-04-25  Ulrich Drepper  <drepper@redhat.com>
 146
 147         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
 148         now.  First gcc must be fixed (more concrete: libgcc).
 149
 150 2000-04-24  Ulrich Drepper  <drepper@redhat.com>
 151
 152         * pthread.c: Remove special treatement for interrupt handlers on x86.
 153         * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.

 155         necessary.
 156         * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h".
 157
 158 2000-04-24  Mark Kettenis  <kettenis@gnu.org>
 159
 160         * join.c (pthread_exit): Set p_terminated after reporting the
 161         termination event instead of before.
 162
 163 2000-04-20  Jakub Jelinek  <jakub@redhat.com>
 164
 165         * sysdeps/pthread/bits/libc-lock.h: Only declare __pthread_rwlock_*
 166         if __USE_UNIX98.
 167
 168 2000-04-18  Andreas Jaeger  <aj@suse.de>

 189         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
 190         (pthread_getcpuclockid): Don't compare thread_id with thread_self,
 191         use thread_handle().
 192
 193 2000-04-16  Ulrich Drepper  <drepper@redhat.com>
 194
 195         * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
 196         if fast mutex is used.  Don't initialize `already_canceled' twice.
 197         Correctly test for return value of timedsuspend.
 198
 199         * pthread.c: Correct long-time braino.  We never set SA_SIGINFO and
 200         therefore don't need the _rt versions of the signal handlers.
 201

 210         realtime signals are known to exist.
 211
 212         * pthread.c: Is __ASSUME_REALTIME_SIGNALS then avoid generating code
 213         to dynamically detect RT signals and avoid generating compatibility
 214         functions with old kernel.
 215         * restart.h (restart) [__ASSUME_REALTIME_SIGNALS]: Use
 216         __pthread_restart_new directly.
 217         (suspend) [__ASSUME_REALTIME_SIGNALS]: Use

 235         suspension function through __pthread_timedsuspend.
 236         * semaphore.c (sem_timedwait): Use timedsuspend, don't duplicate
 237         the code.
 238         Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
 239

 532         Redesigned how cancellation unblocks a thread from internal
 533         cancellation points (sem_wait, pthread_join,
 534         pthread_cond_{wait,timedwait}).
 535         Cancellation won't eat a signal in any of these functions
 536         (*required* by POSIX and Single Unix Spec!).
 537         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
 538         simultaneous condition variable signal (not required by POSIX
 539         or Single Unix Spec, but nice).
 540         * spinlock.c: __pthread_lock queues back any received restarts
 541         that don't belong to it instead of assuming ownership of lock
 542         upon any restart; fastlock can no longer be acquired by two threads
 543         simultaneously.
 544         * restart.h: Restarts queue even on kernels that don't have
 545         queued real time signals (2.0, early 2.1), thanks to atomic counter,
 546         avoiding a rare race condition in pthread_cond_timedwait.

 589
 590         * manager.c (pthread_allocate_stack): Correct computation of
 591         new_thread_bottom.  Correct handling of stack size and when the
 592         rlimit method to guard for stack growth is used.
 593         * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
 594         minus one pagesize (not two).

1801         * linuxtheads/pthread.c (__pthread_initial_thread): Correct
1802         initializer.
1803         (__pthread_manager_thread): Likewise.

1808         Since sigset_t no longer fits in a register, we can't pass in the
1809         thread's initial mask so easily.  Take this opportunity to simplify
1810         the clone implementation by only accepting a single void* argument.
1811
1812         * linuxthreads/manager.c (__pthread_manager): Put thread vitals
1813         in the thread struct instead of as arguments through clone.
1814         (pthread_start_thread): Look for them there.
1815         * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
1816         p_initial_fn_arg, p_initial_mask.  Fix __pthread_manager proto.
1817         * linuxthreads/pthread.c (pthread_initialize_manager): Revise
1818         clone invocation.
