3826 Changes documentation for pthread_mutexattr_setkind_np() and
3827 pthread_mutexattr_getkind_np() over to the Unix98 APIs for the
3828 same: pthread_mutexattr_settype() and pthread_mutexattr_gettype().
3829 Changes references to PTHREAD_MUTEXATTR_FAST_NP to
3830 PTHREAD_MUTEXATTR_ADAPTIVE_NP.
3831 Begins to introduce discussion of the ``timed'' mutex type. This

4410 2000-06-19 H.J. Lu <hjl@gnu.org>
4412 * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
4413 HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
4414 (compare_and_swap_with_release_semantics): New. Default to
4415 compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
4418 * spinlock.c (__pthread_unlock): Call
4419 compare_and_swap_with_release_semantics () instead of
4420 compare_and_swap ().
4422 2000-06-19 Ulrich Drepper <drepper@redhat.com>
4424 * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning

4431 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4433 Timer nodes are now reference counted, and can be marked
4434 as deleted. This allows for the safe release of the global mutex
4435 in the middle without losing the timer being operated on.
4437 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
4438 member is now an enum with three values, so that an intermediate
4439 state can be represented (deleted but not free for reuse yet).
4440 New refcount member added.
4441 * sysdeps/pthread/timer_routines.c: Likewise.
4443 * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
4444 timer_valid): New inline functions added.
4446 * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4447 restructured, recursive deadlock bug fixed.
4449 * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4450 timer_addref to ensure that timer won't be deleted while mutex is not
4451 held. Also uses timer_invalid to perform validation of timer handle.
4452 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4453 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4455 2000-06-14 Ulrich Drepper <drepper@redhat.com>
4457 * shlib-versions: Add entry for SH.

4460 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4462 A few optimizations. Got rid of unnecessary wakeups of timer threads,
4463 tightened up some critical regions and micro-optimized some list
4466 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4467 Returns int value now to indicate whether timer was queued at head.
4468 * sysdeps/pthread/posix-timer.h: Likewise.
4469 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4470 new return value from __timer_thread_queue_timer to avoid waking
4471 up timer thread unnecessarily.
4473 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4474 inuse flag, because this requires mutex to be held. Callers updated
4475 to do the check when they have the mutex.
4476 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4478 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4479 regions: avoids making system calls while holding timer mutex, and
4480 a few computations were moved outside of the mutex as well.
4481 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4483 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4484 to list_unlink_ip, meaning idempotent. Pointer manipulation
4485 changed to get better better code out of gcc.
4486 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4487 version of list_unlink added here.
4488 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4489 function in all places: idempotent one for timers, non-idempotent
4490 one for thread nodes.
4491 * sysdeps/pthread/timer_settime: Likewise.
4492 * sysdeps/pthread/timer_routines.c: Likewise.
4494 2000-06-13 Ulrich Drepper <drepper@redhat.com>
4496 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
4497 * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.

4518 (__pthread_spin_init): Implement.
4519 (__pthread_spin_destroy): Implement.
4521 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4523 * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4524 really append the entry.
4526 2000-06-10 Andreas Jaeger <aj@suse.de>
4528 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
4530 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
4532 * sysdeps/pthread/timer_create.c: Thread matching now done on
4533 clock type as well as thread attributes.
4534 There are individual global signal-delivering threads for
4535 different clock types.
4536 * sysdeps/pthread/posix-timer.h: Likewise.
4537 * sysdeps/pthread/timer_routines.c: Likewise.
4539 * sysdeps/pthread/timer_routines.c: Thread allocation and
4540 deallocation function now remembers to put thread on active
4541 list and remove from active list.
4542 Thus now the feature of binding multiple timers
4543 to a single thread actually works.
4545 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4547 * pthread.c (__pthread_create_2_1): Optimize a bit.
4549 * internals.h (invalid_handle): Also test for p_terminated != 0.
4550 (nonexisting_handle): New function. Same as old invalid_handle.
4551 * join.c (pthread_join): Use nonexisting_handle instead of
4552 invalid_handle to test for acceptable thread handle.
4553 * manager.c (pthread_handle_free): Likewise.
4554 * joinrace.c: New file.
4555 Reported by Permaine Cheung <pcheung@cygnus.com>.
4557 2000-06-08 Ulrich Drepper <drepper@redhat.com>
4559 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4560 Correct handling of matching variable.

4565 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4566 Be prepared for empty timer list.
4568 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
4569 CPUTIME clock ID. Add support for thread clocks.
4571 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
4572 subtraction were switched.
4574 * sysdeps/pthread/timer_routines.c (init_module): Use
4575 THREAD_MAXNODES threads.

4578 * sysdeps/pthread/timer_create.c: Fill in creator_pid.
4579 * sysdeps/pthread/timer_routines.c (thread_expire_timer): Send signal
4580 with sigqueueinfo is this system call is available.

4583 CLOCK_CPUTIME if _POSIX_CPUTIME is defined.
4585 * sysdeps/pthread/Makefile: New file. Add rules to build timer
4587 * sysdeps/unix/sysv/linux/bits/local_lim.h: Add TIMER_MAX.

4600 2000-06-08 Ulrich Drepper <drepper@redhat.com>
4602 * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and
4603 LINK_MAX definitions if necessary.
4605 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
4607 Added missing fork time handling of global libio lock.
4609 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4610 not just the individual stream locks. Rewritten to use new
4611 iterator interface provided by libio rather than accessing
4614 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4615 which lock and unlock the stream list using the new interface
4617 * internals.h: Likewise.
4619 * ptfork.c (__fork): Now calls __flockfilelist before fork,
4620 and __funlockfilelist in the parent after the fork.
4621 Child still calls __fresetlockfiles as before.
4623 * linuxthreads.texi: Now explains what happens to streams at
4624 fork time. Also whole new section on forking and thread added.
4625 Definition of pthread_atfork moved out of Miscellaneous Functions
4626 to this new section.
4628 2000-06-04 Jakub Jelinek <jakub@redhat.com>
4630 * sysdeps/sparc/sparc32/sparcv9/pspinlock.c (__pthread_spin_lock):

4649 * Examples/ex8.c: New file.
4651 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
4653 Bugfix: The pthread_atfork mechanism now takes care of its
4654 own internal mutex at fork time.
4656 * ptfork.c (__fork): Revised so that the mutex is held across
4657 the fork operation and while the handlers are called, and so that
4658 the child resets the mutex.
4660 * linuxthreads.texi: Updated pthread_atfork documentation to make
4661 it clear that fork and pthread_atfork can't be reentered from
4662 atfork handlers, that pthread_atfork and fork are mutually atomic,
4663 and that the handlers are inherited by the child process.
4665 2000-05-24 Ulrich Drepper <drepper@redhat.com>
4667 * Makefile (libpthread-routines): Add pspinlock.
4668 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.
4669 Use struct _pthread_fastlock instead of pthread_spinlock_t.
4670 * condvar.c: Likewise.
4671 * internals.h: Likewise.

4702 * internals.h (__RES_PTHREAD_INTERNAL): Define.
4704 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
4706 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4707 object state is represented with additional bits which distinguish
4708 whether that state was set up in the current process, or
4709 in an ancestor process. If that state was set in an ancestor,
4710 it means that a fork happened while thread was executing the init
4711 function. In that case, the state is reset to NEVER.
4712 * mutex.c (__pthread_once_fork_prepare): New function.
4713 (__pthread_once_fork_child): Likewise
4714 (__pthread_once_fork_parent): Likewise
4715 (__pthread_reset_pthread_once): Removed.
4716 * ptfork.c (__fork): Call new handlers in mutex.c.

4724 * internals.h: New thread manager request type, REQ_KICK.
4725 * join.c (pthread_exit): main thread now calls exit() instead
4726 of _exit() in order to proper process cleanup.
4727 * manager.c (__pthread_manager): Do not terminate manager
4728 after unblocking main thread; wait for main thread's
4729 REQ_PROCESS_EXIT request instead.
4730 Also, added REQ_KICK case to handle new request; this just does
4732 * manager.c (pthread_exited): Do not terminate manager after
4733 unblocking main thread.
4734 * manager.c (__pthread_manager_sighandler): If the main thread
4735 is waiting for all other threads to die, send a REQ_KICK into
4736 the thread manager request pipe to get it to clean out the threads
4737 and unblock the main thread as soon as possible. This fixes
4738 the 2000 millisecond hang on shutdown bug.
4739 * Examples/ex7.c: New file, tests shutdown behavior when all threads
4740 including the main one call pthread_exit(), or implicitly do so.
4741 * Makefile (tests): Add ex7.
4743 2000-05-05 Andreas Jaeger <aj@suse.de>

4758 2000-04-29 Bruno Haible <haible@clisp.cons.org>
4760 * join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
4761 for eventmask larger than 1 word.
4763 2000-04-27 Ulrich Drepper <drepper@redhat.com>
4765 * Versions [libpthread] (GLIBC_2.2): Add __pthread_initialize_minimal.

4767 minimal initialization.
4768 (pthread_initialize): Remove this code here.
4769 * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again. We
4770 are working around the problem in glibc.
4772 2000-04-25 Ulrich Drepper <drepper@redhat.com>
4774 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
4775 now. First gcc must be fixed (more concrete: libgcc).
4777 2000-04-24 Ulrich Drepper <drepper@redhat.com>
4779 * pthread.c: Remove special treatement for interrupt handlers on x86.
4780 * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.
4781 * sysdeps/i386/useldt.h: Use "q" constraint instead of "r" where
4783 * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h".
4785 2000-04-24 Mark Kettenis <kettenis@gnu.org>
4787 * join.c (pthread_exit): Set p_terminated after reporting the
4788 termination event instead of before.
4790 2000-04-20 Jakub Jelinek <jakub@redhat.com>
4792 * sysdeps/pthread/bits/libc-lock.h: Only declare __pthread_rwlock_*
4795 2000-04-18 Andreas Jaeger <aj@suse.de>
4797 * Versions: Use ld instead of ld.so.
4799 2000-04-18 Jakub Jelinek <jakub@redhat.com>
4801 * sysdeps/unix/sysv/linux/sparc/bits/sigcontext.h (struct sigcontext):

4816 * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
4817 (pthread_getcpuclockid): Don't compare thread_id with thread_self,
4818 use thread_handle().
4820 2000-04-16 Ulrich Drepper <drepper@redhat.com>
4822 * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
4823 if fast mutex is used. Don't initialize `already_canceled' twice.
4824 Correctly test for return value of timedsuspend.
4826 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
4827 therefore don't need the _rt versions of the signal handlers.
4829 2000-04-15 Ulrich Drepper <drepper@redhat.com>
4831 * pthread.c (pthread_yield): New function.
4832 * sysdeps/pthread/pthread.h (pthread_yield): Add prototype.
4833 * Versions [libpthread] (GLIBC_2.2): Add pthread_yield.
4834 * internals.h: Declare __pthread_yield.
4836 * pthread.c (pthread_initialize): Avoid a bit more code if
4837 realtime signals are known to exist.
4839 * pthread.c: Is __ASSUME_REALTIME_SIGNALS then avoid generating code
4840 to dynamically detect RT signals and avoid generating compatibility
4841 functions with old kernel.
4842 * restart.h (restart) [__ASSUME_REALTIME_SIGNALS]: Use
4843 __pthread_restart_new directly.
4844 (suspend) [__ASSUME_REALTIME_SIGNALS]: Use

5159 Redesigned how cancellation unblocks a thread from internal
5160 cancellation points (sem_wait, pthread_join,
5161 pthread_cond_{wait,timedwait}).
5162 Cancellation won't eat a signal in any of these functions
5163 (*required* by POSIX and Single Unix Spec!).
5164 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5165 simultaneous condition variable signal (not required by POSIX
5166 or Single Unix Spec, but nice).
5167 * spinlock.c: __pthread_lock queues back any received restarts
5168 that don't belong to it instead of assuming ownership of lock
5169 upon any restart; fastlock can no longer be acquired by two threads
5171 * restart.h: Restarts queue even on kernels that don't have
5172 queued real time signals (2.0, early 2.1), thanks to atomic counter,
5173 avoiding a rare race condition in pthread_cond_timedwait.

5215 pwrite64, lseek64, open64, and __open64.

5218 new_thread_bottom. Correct handling of stack size and when the
5219 rlimit method to guard for stack growth is used.
5220 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
5221 minus one pagesize (not two).
5223 1999-12-03 Andreas Jaeger <aj@suse.de>
