linuxthreads/ChangeLog

   1 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
   2
   3         * sysdeps/pthread/timer_create.c: Thread matching now done on
   4         clock type as well as thread attributes.
   5         There are individual global signal-delivering threads for
   6         different clock types.
   7         * sysdeps/pthread/posix-timer.h: Likewise.
   8         * sysdeps/pthread/timer_routines.c: Likewise.
   9
  10         * sysdeps/pthread/timer_routines.c: Thread allocation and
  11         deallocation function now remembers to put thread on active
  12         list and remove from active list.
  13         Thus now the feature of binding multiple timers
  14         to a single thread actually works.
  15
  16 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
  17
  18         * pthread.c (__pthread_create_2_1): Optimize a bit.
  19
  20         * internals.h (invalid_handle): Also test for p_terminated != 0.
  21         (nonexisting_handle): New function.  Same as old invalid_handle.
  22         * join.c (pthread_join): Use nonexisting_handle instead of
  23         invalid_handle to test for acceptable thread handle.
  24         * manager.c (pthread_handle_free): Likewise.
  25         * joinrace.c: New file.
  26         Reported by Permaine Cheung <pcheung@cygnus.com>.

  34         avoid warnings.
  35
  36         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
  37         Be prepared for empty timer list.
  38
  39         * sysdeps/pthread/timer_create.c (timer_create): Correct names of
  40         CPUTIME clock ID.  Add support for thread clocks.
  41
  42         * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
  43         subtraction were switched.
  44
  45         * sysdeps/pthread/timer_routines.c (init_module): Use
  46         THREAD_MAXNODES threads.
  47
  48         * sysdeps/pthread/posix-timer.h (struct timer_node): Add creator_pid.
  49         * sysdeps/pthread/timer_create.c: Fill in creator_pid.
  50         * sysdeps/pthread/timer_routines.c (thread_expire_timer): Send signal
  51         with sigqueueinfo is this system call is available.
  52
  53         * sysdeps/pthread/timer_create.c (timer_create): Allow

  70
  71 2000-06-08  Ulrich Drepper  <drepper@redhat.com>
  72
  73         * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and
  74         LINK_MAX definitions if necessary.
  75
  76 2000-06-04  Kaz Kylheku  <kaz@ashi.footprints.net>
  77
  78         Added missing fork time handling of global libio lock.
  79
  80         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
  81         not just the individual stream locks. Rewritten to use new
  82         iterator interface provided by libio rather than accessing
  83         global variable.
  84
  85         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
  86         which lock and unlock the stream list using the new interface
  87         provied by libio.
  88         * internals.h: Likewise.
  89
  90         * ptfork.c (__fork): Now calls __flockfilelist before fork,
  91         and __funlockfilelist in the parent after the fork.
  92         Child still calls __fresetlockfiles as before.
  93
  94         * linuxthreads.texi: Now explains what happens to streams at
  95         fork time. Also whole new section on forking and thread added.
  96         Definition of pthread_atfork moved out of Miscellaneous Functions
  97         to this new section.
  98
  99 2000-06-04  Jakub Jelinek  <jakub@redhat.com>
 100
 101         * sysdeps/sparc/sparc32/sparcv9/pspinlock.c (__pthread_spin_lock):
 102         Add missing register.
 103         * sysdeps/sparc/sparc64/pspinlock.c (__pthread_spin_lock): Likewise.
 104

 106
 107         * sysdeps/sparc/sparc32/pspinlock.c: Implement spinlocks.
 108         * sysdeps/sparc/sparc32/sparcv9/pspinlock.c: New.
 109         * sysdeps/sparc/sparc64/pspinlock.c: Implement spinlocks.
 110
 111 2000-05-31  Andreas Jaeger  <aj@suse.de>
 112
 113         * sysdeps/mips/pspinlock.c: Implement spinlocks.
 114
 115 2000-05-28  Ulrich Drepper  <drepper@redhat.com>
 116
 117         * spinlock.c (__pthread_lock): Remove ASSERT.
 118
 119         * Makefile (tests): Add ex8.
 120         * Examples/ex8.c: New file.
 121
 122 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
 123
 124         Bugfix: The pthread_atfork mechanism now takes care of its
 125         own internal mutex at fork time.
 126
 127         * ptfork.c (__fork): Revised so that the mutex is held across
 128         the fork operation and while the handlers are called, and so that
 129         the child resets the mutex.
 130
 131         * linuxthreads.texi: Updated pthread_atfork documentation to make
 132         it clear that fork and pthread_atfork can't be reentered from
 133         atfork handlers, that pthread_atfork and fork are mutually atomic,
 134         and that the handlers are inherited by the child process.
 135
 136 2000-05-24  Ulrich Drepper  <drepper@redhat.com>
 137
 138         * Makefile (libpthread-routines): Add pspinlock.
 139         * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

 141         * condvar.c: Likewise.
 142         * internals.h: Likewise.
 143         * join.c: Likewise.

 149         * signals.c: Likewise.
 150         * spinlock.h: Likewise.
 151         * spinlock.c: Likewise.  Remove pthread_spin_lock functions.

 160         * sysdeps/pthread/bits/pthreadtypes.h: Remove pthread_spinlock_t
 161         back to _pthread_fastlock.  Define new pthread_spinlock_t.
 162
 163 2000-05-24  Andreas Jaeger  <aj@suse.de>
 164
 165         * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.
 166
 167 2000-05-21  Jakub Jelinek  <jakub@redhat.com>
 168
 169         * manager.c (pthread_handle_create): Initialize p_res._sock to -1.
 170
 171 2000-05-13  Jakub Jelinek  <jakub@redhat.com>
 172
 173         * internals.h (__RES_PTHREAD_INTERNAL): Define.
 174
 175 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
 176
 177         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
 178         object state is represented with additional bits which distinguish
 179         whether that state was set up in the current process, or
 180         in an ancestor process. If that state was set in an ancestor,
 181         it means that a fork happened while thread was executing the init
 182         function. In that case, the state is reset to NEVER.
 183         * mutex.c (__pthread_once_fork_prepare): New function.
 184         (__pthread_once_fork_child): Likewise
 185         (__pthread_once_fork_parent): Likewise
 186         (__pthread_reset_pthread_once): Removed.
 187         * ptfork.c (__fork): Call new handlers in mutex.c.
 188         * internals.h: Declarations of new mutex.c functions added.
 189         Declaration of removed function deleted.
 190         * linuxthreads.texi: Updated documentation about pthread_once
 191         to clarify what happens under cancellation and forking.
 192
 193 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
 194
 195         * internals.h: New thread manager request type, REQ_KICK.
 196         * join.c (pthread_exit): main thread now calls exit() instead
 197         of _exit() in order to proper process cleanup.
 198         * manager.c (__pthread_manager): Do not terminate manager
 199         after unblocking main thread; wait for main thread's
 200         REQ_PROCESS_EXIT request instead.
 201         Also, added REQ_KICK case to handle new request; this just does
 202         nothing.
 203         * manager.c (pthread_exited): Do not terminate manager after
 204         unblocking main thread.
 205         * manager.c (__pthread_manager_sighandler): If the main thread
 206         is waiting for all other threads to die, send a REQ_KICK into
 207         the thread manager request pipe to get it to clean out the threads
 208         and unblock the main thread as soon as possible. This fixes
 209         the 2000 millisecond hang on shutdown bug.
 210         * Examples/ex7.c: New file, tests shutdown behavior when all threads
 211         including the main one call pthread_exit(), or implicitly do so.
 212         * Makefile (tests): Add ex7.
 213
 214 2000-05-05  Andreas Jaeger  <aj@suse.de>
 215
 216         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
 217         (pthread_getcpuclockid): Correct test for ourselves.
 218
 219 2000-05-05  Ulrich Drepper  <drepper@redhat.com>
 220
 221         * internals.h (struct _pthread_descr_struct): Reorganization.
 222         Allocate room for 16 pointers at head of the structure for future
 223         thread-local data handling.  Move p_self member in this area.
 224         * manager.c (pthread_handle_create): Adjust use of p_self.
 225         * sysdeps/i386/useldt.h (THREAD_SELF): Likewise.
 226         * pthread.c (__pthread_initial_thread): Adjust initialization.
 227         (__pthread_manager_thread): Likewise.

 229 2000-04-29  Bruno Haible  <haible@clisp.cons.org>
 230
 231         * join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
 232         for eventmask larger than 1 word.
 233
 234 2000-04-27  Ulrich Drepper  <drepper@redhat.com>
 235
 236         * Versions [libpthread] (GLIBC_2.2): Add __pthread_initialize_minimal.
 237         * pthread.c (__pthread_initialize_minimal): New function.  Perform
 238         minimal initialization.
 239         (pthread_initialize): Remove this code here.
 240         * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again.  We
 241         are working around the problem in glibc.
 242
 243 2000-04-25  Ulrich Drepper  <drepper@redhat.com>
 244
 245         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
 246         now.  First gcc must be fixed (more concrete: libgcc).
 247
 248 2000-04-24  Ulrich Drepper  <drepper@redhat.com>
 249
 250         * pthread.c: Remove special treatement for interrupt handlers on x86.
 251         * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.
 252         * sysdeps/i386/useldt.h: Use "q" constraint instead of "r" where
 253         necessary.
 254         * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h".
 255
 256 2000-04-24  Mark Kettenis  <kettenis@gnu.org>
 257
 258         * join.c (pthread_exit): Set p_terminated after reporting the
 259         termination event instead of before.
 260
 261 2000-04-20  Jakub Jelinek  <jakub@redhat.com>
 262
 263         * sysdeps/pthread/bits/libc-lock.h: Only declare __pthread_rwlock_*
 264         if __USE_UNIX98.
 265
 266 2000-04-18  Andreas Jaeger  <aj@suse.de>
 267
 268         * Versions: Use ld instead of ld.so.
 269
 270 2000-04-18  Jakub Jelinek  <jakub@redhat.com>
 271
 272         * sysdeps/unix/sysv/linux/sparc/bits/sigcontext.h (struct sigcontext):
 273         Remove the typedef keyword.
 274
 275 2000-04-18  Jakub Jelinek  <jakub@redhat.com>
 276
 277         * sysdeps/sparc/sparc64/pt-machine.h (MEMORY_BARRIER): Use membar,
 278         not stbar.
 279         (READ_MEMORY_BARRIER): Define.
 280         * spinlock.c (__pthread_spin_unlock): Use READ_MEMORY_BARRIER, not
 281         MEMORY_BARRIER.
 282         * internals.h (READ_MEMORY_BARRIER): Define if not defined in sysdep
 283         headers.
 284

 287         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
 288         (pthread_getcpuclockid): Don't compare thread_id with thread_self,
 289         use thread_handle().
 290
 291 2000-04-16  Ulrich Drepper  <drepper@redhat.com>
 292
 293         * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
 294         if fast mutex is used.  Don't initialize `already_canceled' twice.
 295         Correctly test for return value of timedsuspend.
 296
 297         * pthread.c: Correct long-time braino.  We never set SA_SIGINFO and
 298         therefore don't need the _rt versions of the signal handlers.
 299
 300 2000-04-15  Ulrich Drepper  <drepper@redhat.com>

 308         realtime signals are known to exist.
 309
 310         * pthread.c: Is __ASSUME_REALTIME_SIGNALS then avoid generating code
 311         to dynamically detect RT signals and avoid generating compatibility
 312         functions with old kernel.
 313         * restart.h (restart) [__ASSUME_REALTIME_SIGNALS]: Use
 314         __pthread_restart_new directly.
 315         (suspend) [__ASSUME_REALTIME_SIGNALS]: Use
 316         __pthread_wait_for_restart_signal directly.
 317         (timedsuspend) [__ASSUME_REALTIME_SIGNALS]: Use
 318         __pthread_timedsuspend_new directly.
 319
 320 2000-04-15  Ulrich Drepper  <drepper@redhat.com>
 321
 322         * condvar.c: Remove all the special code to handle cond_timedwait.

 333         suspension function through __pthread_timedsuspend.
 334         * semaphore.c (sem_timedwait): Use timedsuspend, don't duplicate
 335         the code.
 336         Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
 337
 338         * internals.h (WRITE_MEMORY_BARRIER): Define as MEMORY_BARRIER if
 339         undefined.
 340         * spinlock.c: Use WRITE_MEMORY_BARRIER instead of MEMORY_BARRIER

 630         Redesigned how cancellation unblocks a thread from internal
 631         cancellation points (sem_wait, pthread_join,
 632         pthread_cond_{wait,timedwait}).
 633         Cancellation won't eat a signal in any of these functions
 634         (*required* by POSIX and Single Unix Spec!).
 635         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
 636         simultaneous condition variable signal (not required by POSIX
 637         or Single Unix Spec, but nice).
 638         * spinlock.c: __pthread_lock queues back any received restarts
 639         that don't belong to it instead of assuming ownership of lock
 640         upon any restart; fastlock can no longer be acquired by two threads
 641         simultaneously.
 642         * restart.h: Restarts queue even on kernels that don't have
 643         queued real time signals (2.0, early 2.1), thanks to atomic counter,
 644         avoiding a rare race condition in pthread_cond_timedwait.
 645
 646 1999-12-31  Andreas Jaeger  <aj@suse.de>

 692         minus one pagesize (not two).

1905
1906         Since sigset_t no longer fits in a register, we can't pass in the
1907         thread's initial mask so easily.  Take this opportunity to simplify
1908         the clone implementation by only accepting a single void* argument.
1909
1910         * linuxthreads/manager.c (__pthread_manager): Put thread vitals
1911         in the thread struct instead of as arguments through clone.
1912         (pthread_start_thread): Look for them there.
1913         * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
1914         p_initial_fn_arg, p_initial_mask.  Fix __pthread_manager proto.
1915         * linuxthreads/pthread.c (pthread_initialize_manager): Revise
1916         clone invocation.
