2443 under [HAVE_TLS_SUPPORT] so we can rely on the initialization done

4249 (__pthread_mutex_timedlock): New function.
4250 (__pthread_mutex_unlock): Use __pthread_alt_unlock for
4251 PTHREAD_MUTEX_ERRORCHECK_NP. Handle PTHREAD_MUTEX_TIMED_NP.
4252 (__pthread_mutexattr_init): Use PTHREAD_MUTEX_TIMED_NP.
4253 (__pthread_mutexattr_settype): Allow PTHREAD_MUTEX_TIMED_NP.

4285 * sysdeps/pthread/bits/pthreadtypes.h: Likewise.
4286 Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
4288 2000-06-19 H.J. Lu <hjl@gnu.org>
4290 * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
4291 HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
4292 (compare_and_swap_with_release_semantics): New. Default to
4293 compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
4294 is not defined.
4296 * spinlock.c (__pthread_unlock): Call
4297 compare_and_swap_with_release_semantics () instead of
4298 compare_and_swap ().
4300 2000-06-19 Ulrich Drepper <drepper@redhat.com>
4302 * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning
4303 to errno directly.
4304 * sysdeps/pthread/timer_delete.c: Likewise.
4305 * sysdeps/pthread/timer_getoverr.c: Likewise.
4306 * sysdeps/pthread/timer_gettime.c: Likewise.
4307 * sysdeps/pthread/timer_settime.c: Likewise.
4309 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4311 Timer nodes are now reference counted, and can be marked
4312 as deleted. This allows for the safe release of the global mutex
4313 in the middle without losing the timer being operated on.
4315 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
4316 member is now an enum with three values, so that an intermediate
4317 state can be represented (deleted but not free for reuse yet).
4318 New refcount member added.
4319 * sysdeps/pthread/timer_routines.c: Likewise.
4321 * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4322 timer_valid): New inline functions added.
4324 * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4325 restructured, recursive deadlock bug fixed.
4327 * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4328 timer_addref to ensure that timer won't be deleted while mutex is not
4329 held. Also uses timer_invalid to perform validation of timer handle.
4330 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4331 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4333 2000-06-14 Ulrich Drepper <drepper@redhat.com>
4335 * shlib-versions: Add entry for SH.
4336 Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4338 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4340 A few optimizations. Got rid of unnecessary wakeups of timer threads,
4341 tightened up some critical regions and micro-optimized some list
4342 manipulation code.
4344 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4345 Returns int value now to indicate whether timer was queued at head.
4346 * sysdeps/pthread/posix-timer.h: Likewise.
4347 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4348 new return value from __timer_thread_queue_timer to avoid waking
4349 up timer thread unnecessarily.
4351 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4352 inuse flag, because this requires mutex to be held. Callers updated
4353 to do the check when they have the mutex.
4354 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4356 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4357 regions: avoids making system calls while holding timer mutex, and
4358 a few computations were moved outside of the mutex as well.
4359 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4361 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4362 to list_unlink_ip, meaning idempotent. Pointer manipulation
4363 changed to get better better code out of gcc.
4364 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4365 version of list_unlink added here.
4366 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4367 function in all places: idempotent one for timers, non-idempotent
4368 one for thread nodes.
4369 * sysdeps/pthread/timer_settime: Likewise.
4370 * sysdeps/pthread/timer_routines.c: Likewise.
4372 2000-06-13 Ulrich Drepper <drepper@redhat.com>
4374 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
4375 * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.
4377 * sysdeps/pthread/Makefile: Remove tests definition.
4379 2000-06-12 Kazumoto Kojima <kkojima@rr.iij4u.or.jp>

4389 * Examples/ex6.c: Test return value of pthread_join.
4391 2000-06-11 Geoff Keating <geoffk@cygnus.com>
4393 * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4394 (__pthread_spin_trylock): Implement.
4395 (__pthread_spin_unlock): Implement.
4396 (__pthread_spin_init): Implement.
4397 (__pthread_spin_destroy): Implement.
4399 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4401 * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4402 really append the entry.
4404 2000-06-10 Andreas Jaeger <aj@suse.de>
4406 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
4408 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
4410 * sysdeps/pthread/timer_create.c: Thread matching now done on
4411 clock type as well as thread attributes.
4412 There are individual global signal-delivering threads for
4413 different clock types.
4414 * sysdeps/pthread/posix-timer.h: Likewise.
4415 * sysdeps/pthread/timer_routines.c: Likewise.
4417 * sysdeps/pthread/timer_routines.c: Thread allocation and
4418 deallocation function now remembers to put thread on active
4419 list and remove from active list.
4420 Thus now the feature of binding multiple timers
4421 to a single thread actually works.
4423 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4425 * pthread.c (__pthread_create_2_1): Optimize a bit.
4427 * internals.h (invalid_handle): Also test for p_terminated != 0.
4428 (nonexisting_handle): New function. Same as old invalid_handle.
4429 * join.c (pthread_join): Use nonexisting_handle instead of
4430 invalid_handle to test for acceptable thread handle.
4431 * manager.c (pthread_handle_free): Likewise.
4432 * joinrace.c: New file.
4433 Reported by Permaine Cheung <pcheung@cygnus.com>.
4435 2000-06-08 Ulrich Drepper <drepper@redhat.com>
4437 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4438 Correct handling of matching variable.
4440 * sysdeps/pthread/tst-timer.c (main): Rewrite initializers to
4441 avoid warnings.
4443 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4444 Be prepared for empty timer list.
4446 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
4447 CPUTIME clock ID. Add support for thread clocks.
4449 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
4450 subtraction were switched.
4452 * sysdeps/pthread/timer_routines.c (init_module): Use
4453 THREAD_MAXNODES threads.
4455 * sysdeps/pthread/posix-timer.h (struct timer_node): Add creator_pid.
4456 * sysdeps/pthread/timer_create.c: Fill in creator_pid.
4457 * sysdeps/pthread/timer_routines.c (thread_expire_timer): Send signal
4458 with sigqueueinfo is this system call is available.
4460 * sysdeps/pthread/timer_create.c (timer_create): Allow
4461 CLOCK_CPUTIME if _POSIX_CPUTIME is defined.
4463 * sysdeps/pthread/Makefile: New file. Add rules to build timer
4464 functionality.
4465 * sysdeps/unix/sysv/linux/bits/local_lim.h: Add TIMER_MAX.
4467 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>

4476 * sysdeps/pthread/tst-timer.c: New file.
4478 2000-06-08 Ulrich Drepper <drepper@redhat.com>
4480 * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and
4481 LINK_MAX definitions if necessary.
4483 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
4485 Added missing fork time handling of global libio lock.
4487 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4488 not just the individual stream locks. Rewritten to use new
4489 iterator interface provided by libio rather than accessing
4490 global variable.
4492 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4493 which lock and unlock the stream list using the new interface
4494 provied by libio.
4495 * internals.h: Likewise.
4497 * ptfork.c (__fork): Now calls __flockfilelist before fork,
4498 and __funlockfilelist in the parent after the fork.
4499 Child still calls __fresetlockfiles as before.
4501 * linuxthreads.texi: Now explains what happens to streams at
4502 fork time. Also whole new section on forking and thread added.
4503 Definition of pthread_atfork moved out of Miscellaneous Functions
4504 to this new section.
4506 2000-06-04 Jakub Jelinek <jakub@redhat.com>
4508 * sysdeps/sparc/sparc32/sparcv9/pspinlock.c (__pthread_spin_lock):

4524 * spinlock.c (__pthread_lock): Remove ASSERT.
4526 * Makefile (tests): Add ex8.
4527 * Examples/ex8.c: New file.
4529 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
4531 Bugfix: The pthread_atfork mechanism now takes care of its
4532 own internal mutex at fork time.
4534 * ptfork.c (__fork): Revised so that the mutex is held across
4535 the fork operation and while the handlers are called, and so that
4536 the child resets the mutex.
4538 * linuxthreads.texi: Updated pthread_atfork documentation to make
4539 it clear that fork and pthread_atfork can't be reentered from
4540 atfork handlers, that pthread_atfork and fork are mutually atomic,
4541 and that the handlers are inherited by the child process.
4543 2000-05-24 Ulrich Drepper <drepper@redhat.com>
4545 * Makefile (libpthread-routines): Add pspinlock.
4546 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.
4547 Use struct _pthread_fastlock instead of pthread_spinlock_t.
4548 * condvar.c: Likewise.
4549 * internals.h: Likewise.
4550 * join.c: Likewise.
4551 * manager.c: Likewise.

4567 * sysdeps/pthread/bits/pthreadtypes.h: Remove pthread_spinlock_t
4568 back to _pthread_fastlock. Define new pthread_spinlock_t.
4570 2000-05-24 Andreas Jaeger <aj@suse.de>
4572 * sysdeps/i386/i686/pt-machine.h: Only use LDT on newer kernels.
4574 2000-05-21 Jakub Jelinek <jakub@redhat.com>

4578 2000-05-13 Jakub Jelinek <jakub@redhat.com>
4580 * internals.h (__RES_PTHREAD_INTERNAL): Define.
4582 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
4584 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4585 object state is represented with additional bits which distinguish
4586 whether that state was set up in the current process, or
4587 in an ancestor process. If that state was set in an ancestor,
4588 it means that a fork happened while thread was executing the init
4589 function. In that case, the state is reset to NEVER.
4590 * mutex.c (__pthread_once_fork_prepare): New function.
4591 (__pthread_once_fork_child): Likewise
4592 (__pthread_once_fork_parent): Likewise
4593 (__pthread_reset_pthread_once): Removed.
4594 * ptfork.c (__fork): Call new handlers in mutex.c.
4595 * internals.h: Declarations of new mutex.c functions added.
4596 Declaration of removed function deleted.

4598 to clarify what happens under cancellation and forking.
4600 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
4602 * internals.h: New thread manager request type, REQ_KICK.
4603 * join.c (pthread_exit): main thread now calls exit() instead
4604 of _exit() in order to proper process cleanup.
4605 * manager.c (__pthread_manager): Do not terminate manager
4606 after unblocking main thread; wait for main thread's
4607 REQ_PROCESS_EXIT request instead.
4608 Also, added REQ_KICK case to handle new request; this just does
4609 nothing.
4610 * manager.c (pthread_exited): Do not terminate manager after
4611 unblocking main thread.
4612 * manager.c (__pthread_manager_sighandler): If the main thread
4613 is waiting for all other threads to die, send a REQ_KICK into
4614 the thread manager request pipe to get it to clean out the threads
4615 and unblock the main thread as soon as possible. This fixes
4616 the 2000 millisecond hang on shutdown bug.
4617 * Examples/ex7.c: New file, tests shutdown behavior when all threads
4618 including the main one call pthread_exit(), or implicitly do so.
4619 * Makefile (tests): Add ex7.
4621 2000-05-05 Andreas Jaeger <aj@suse.de>

4636 2000-04-29 Bruno Haible <haible@clisp.cons.org>
4638 * join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
4639 for eventmask larger than 1 word.
4641 2000-04-27 Ulrich Drepper <drepper@redhat.com>
4643 * Versions [libpthread] (GLIBC_2.2): Add __pthread_initialize_minimal.
4644 * pthread.c (__pthread_initialize_minimal): New function. Perform
4645 minimal initialization.
4646 (pthread_initialize): Remove this code here.
4647 * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again. We
4648 are working around the problem in glibc.
4650 2000-04-25 Ulrich Drepper <drepper@redhat.com>
4652 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
4653 now. First gcc must be fixed (more concrete: libgcc).
4655 2000-04-24 Ulrich Drepper <drepper@redhat.com>
4657 * pthread.c: Remove special treatement for interrupt handlers on x86.
4658 * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.
4659 * sysdeps/i386/useldt.h: Use "q" constraint instead of "r" where
4660 necessary.
4661 * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h".
4663 2000-04-24 Mark Kettenis <kettenis@gnu.org>
4665 * join.c (pthread_exit): Set p_terminated after reporting the
4666 termination event instead of before.
4668 2000-04-20 Jakub Jelinek <jakub@redhat.com>
4670 * sysdeps/pthread/bits/libc-lock.h: Only declare __pthread_rwlock_*
4671 if __USE_UNIX98.

4685 not stbar.
4686 (READ_MEMORY_BARRIER): Define.
4687 * spinlock.c (__pthread_spin_unlock): Use READ_MEMORY_BARRIER, not
4688 MEMORY_BARRIER.
4689 * internals.h (READ_MEMORY_BARRIER): Define if not defined in sysdep
4690 headers.
4692 2000-04-17 Ulrich Drepper <drepper@redhat.com>
4694 * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
4695 (pthread_getcpuclockid): Don't compare thread_id with thread_self,
4696 use thread_handle().
4698 2000-04-16 Ulrich Drepper <drepper@redhat.com>
4700 * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
4701 if fast mutex is used. Don't initialize `already_canceled' twice.
4702 Correctly test for return value of timedsuspend.
4704 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
4705 therefore don't need the _rt versions of the signal handlers.
4707 2000-04-15 Ulrich Drepper <drepper@redhat.com>
4709 * pthread.c (pthread_yield): New function.
4710 * sysdeps/pthread/pthread.h (pthread_yield): Add prototype.
4711 * Versions [libpthread] (GLIBC_2.2): Add pthread_yield.
4712 * internals.h: Declare __pthread_yield.
4714 * pthread.c (pthread_initialize): Avoid a bit more code if
4715 realtime signals are known to exist.
4717 * pthread.c: Is __ASSUME_REALTIME_SIGNALS then avoid generating code
4718 to dynamically detect RT signals and avoid generating compatibility
4719 functions with old kernel.
4720 * restart.h (restart) [__ASSUME_REALTIME_SIGNALS]: Use
4721 __pthread_restart_new directly.
4722 (suspend) [__ASSUME_REALTIME_SIGNALS]: Use

4735 (__pthread_timedsuspend_old): New function. Timed suspension
4736 implementation for old Linux kernels.
4737 (__pthread_timedsuspend_new): New function. Timed suspension
4738 implementation for new Linux kernels.
4739 * restart.h (timedsuspend): New function. Call appropriate
4740 suspension function through __pthread_timedsuspend.

5037 Redesigned how cancellation unblocks a thread from internal
5038 cancellation points (sem_wait, pthread_join,
5039 pthread_cond_{wait,timedwait}).
5040 Cancellation won't eat a signal in any of these functions
5041 (*required* by POSIX and Single Unix Spec!).
5042 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5043 simultaneous condition variable signal (not required by POSIX
5044 or Single Unix Spec, but nice).
5045 * spinlock.c: __pthread_lock queues back any received restarts
5046 that don't belong to it instead of assuming ownership of lock
5047 upon any restart; fastlock can no longer be acquired by two threads
5048 simultaneously.
5049 * restart.h: Restarts queue even on kernels that don't have
5050 queued real time signals (2.0, early 2.1), thanks to atomic counter,
5051 avoiding a rare race condition in pthread_cond_timedwait.
5053 1999-12-31 Andreas Jaeger <aj@suse.de>
5055 * internals.h: Remove duplicate prototype declarations.
5057 * weaks.c: Remove __THROW from prototypes since the file is not
5058 compiled by a C++ compiler.

5061 1999-12-30 Andreas Jaeger <aj@suse.de>

5090 * Versions: Export pread, __pread64, pread64, pwrite, __pwrite64,

5092 * wrapsyscall.c: Define pread, __pread64, pread64, pwrite, __pwrite64,
5093 pwrite64, lseek64, open64, and __open64.
5095 * manager.c (pthread_allocate_stack): Correct computation of
5096 new_thread_bottom. Correct handling of stack size and when the
5097 rlimit method to guard for stack growth is used.
5098 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
5099 minus one pagesize (not two).
5101 1999-12-03 Andreas Jaeger <aj@suse.de>
5103 * Versions: Add __res_state with version GLIBC_2.2.
5105 * errno.c (__res_state): New function to return thread specific
5106 resolver state.
5108 * pthread.c (pthread_initialize): Initialize p_resp.
5109 (__pthread_reset_main_thread): Also set p_resp.
5111 * manager.c (pthread_handle_create): Initialize p_resp.

5216 manager.c; include semaphore.h for needed types.
5218 1999-10-08 Ulrich Drepper <drepper@cygnus.com>

5221 directly instead of calling sem_post which should not be necessary
5222 but is faster and might help in some case to work around problems.

6288 __libc_getspecific, __libc_setspecific, and __libc_key_t.
6289 * sysdeps/pthread/stdio-lock.h: Don't care for implementation not
6290 using libio.

6311 Since sigset_t no longer fits in a register, we can't pass in the
6312 thread's initial mask so easily. Take this opportunity to simplify
6313 the clone implementation by only accepting a single void* argument.
6315 * manager.c (__pthread_manager): Put thread vitals in the thread
6316 struct instead of as arguments through clone.
6317 (pthread_start_thread): Look for them there.
6318 * internals.h (struct _pthread): Add p_initial_fn,
6319 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
6320 * pthread.c (pthread_initialize_manager): Revise clone invocation.
