        * semaphore.h (SEM_FAILED): Use 0 not NULL.

2000-02-14  Ulrich Drepper  

        * condvar.c (pthread_cond_timedwait_relative_old): Tight loop with

        nanosleep does not work either.  Get absolute time inside the

        loop.

        (pthread_cond_timedwait_relative_new): Likewise.

        Patch by Kaz Kylheku .

2000-02-13  Ulrich Drepper  

        * condvar.c (pthread_cond_timedwait_relative_old): Undo last patch

        but keep the code around.  A bug in the kernel prevent us from

        using the code.

        (pthread_cond_timedwait_relative_new): Likewise.

        (PR libc/1597 and libc/1598).

2000-02-01  Kaz Kylheku  

        * condvar.c (pthread_cond_timedwait_relative_old): Do tight

        loop around nanosleep calls instead of around most of the function

        (pthread_cond_timedwait_relative_new): Likewise.

        body.  Got rid of backwards goto and one local.

2000-01-31  Ulrich Drepper  

        * condvar.c (pthread_cond_timedwait_relative_old): Recompute time

        before every nanosleep call to account for time spent in the rest

        of the function.

        (pthread_cond_timedwait_relative_new): Likewise.

        Patch by khendricks@ivey.uwo.ca (PR libc/1564).

2000-01-29  Ulrich Drepper  

        * condvar.c (pthread_cond_timedwait_relative_old): Get remaining time

        from nanosleep call so that in case we restart we only wait for the

        remaining time.

        (pthread_cond_timedwait_relative_new): Likewise.

        Patch by khendricks@ivey.uwo.ca (PR libc/1561).

2000-01-18  Ulrich Drepper  

        * manager.c (pthread_allocate_stack): Compute guard page address

        correctly.  Patch by HJ Lu.

2000-01-12  Ulrich Drepper  

        * internals.h (pthread_readlock_info): New structure.

        (_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and

        p_untracked_readlock_count.

        * pthread.c (__pthread_initial_thread, pthread_manager_thread):

        Add initializers for new fields.

        * manager.c (pthread_free): Free read/write lock lists.

        * queue.h (queue_is_empty): New function.

        * rwlock.c: Implement requirements about when readers should get

        locks assigned.

        (PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP): New definition.

        * sysdeps/pthread/bits/pthreadtypes.h (struct _pthread_rwlock_t):

        Define this name as well.

2000-01-06  Andreas Jaeger  

        * pthread.c: Remove extra initializer.

2000-01-05  Ulrich Drepper  

        * pthread.c (__pthread_initial_thread, pthread_manager_thread):

        Adjust initializers for struct _pthread_descr_struct change.

        * internals.h (struct _pthread_descr_struct): Move new elements to

        the end.

2000-01-03  Kaz Kylheku  

        Redesigned how cancellation unblocks a thread from internal

        cancellation points (sem_wait, pthread_join,

        pthread_cond_{wait,timedwait}).

        Cancellation won't eat a signal in any of these functions

        (*required* by POSIX and Single Unix Spec!).

        * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a

        simultaneous condition variable signal (not required by POSIX

        or Single Unix Spec, but nice).

        * spinlock.c: __pthread_lock queues back any received restarts

        that don't belong to it instead of assuming ownership of lock

        upon any restart; fastlock can no longer be acquired by two threads

        simultaneously.

        * restart.h: Restarts queue even on kernels that don't have

        queued real time signals (2.0, early 2.1), thanks to atomic counter,

        avoiding a rare race condition in pthread_cond_timedwait.

1999-12-28  Ulrich Drepper  

        * sysdeps/alpha/pt-machine.h:  Move stack_pointer definition to the

        beginning.

        * manager.c (__pthread_start): Add one more cast to assignment of

        arg to prevent warning on 64bit machines.

1999-12-21  Ulrich Drepper  

        * manager.c (pthread_handle_create): Set p_pid of new thread

        before calling the callback function to report a new thread.

1999-12-20  Andreas Jaeger  

        * pthread.c (pthread_initialize): Move getrlimit call after

        setting of errno.

1999-12-01  Ulrich Drepper  

        * sysdeps/i386/pt-machine.h: Move stack_pointer definition to the

        beginning.

        p_eventbuf.

        * restart.h (suspend_with_cancellation): Rewrite as a macro.

        * condvar.c (pthread_cond_timedwait_relative): Don't mark as inline.

1999-10-21  Xavier Leroy  

        * linuxthreads/pthread.c: For i386, wrap pthread_handle_sigrestart

        and pthread_handle_sigcancel with functions that restore

        %gs from the signal context.  For each signal handling function,

        two wrappers are required, one for a non-RT signal and one for

        a RT signal.

        * linuxthreads/signal.c: For i386, add code to restore %gs

        from the signal context in pthread_sighandler and

        pthread_sighandler_rt.

1999-10-09  Andreas Jaeger  

        * internals.h: Add __new_sem_post to get prototype in

        manager.c; include semaphore.h for needed types.

1999-10-08  Ulrich Drepper  

        * manager.c (__pthread_manager) [REQ_POST]: Use __new_sem_post

        directly instead of calling sem_post which should not be necessary

        but is faster and might help in some case to work around problems.

1999-09-25  Ulrich Drepper  

        * condvar.c (pthread_cond_timedwait_relative): Never return with

        EINTR.  Patch by Andreas Schwab.

1999-09-19  Ulrich Drepper  

        * signals.c (sigaction): Correct last patch.  Don't select

        pthread_sighandler_rt based on the signal number but instead of

        the SA_SIGINFO flag.

1999-09-23  Ulrich Drepper  

        * specific.c: Move definitions of struct pthread_key_struct and

        destr_function to ...

1999-06-23  Robey Pointer  

        * internals.h: Added p_nextlock entry to separate queueing for a

        lock from queueing for a CV (sometimes a thread queues on a lock

        to serialize removing itself from a CV queue).

        * pthread.c: Added p_nextlock to initializers.

        * spinlock.c: Changed to use p_nextlock instead of p_nextwaiting.

1999-05-23  Andreas Jaeger

        and the thread manager runs with a realtime policy, set the

        scheduling policy of the newly created thread back to SCHED_OTHER.

        * manager.c: If the PTHREAD_INHERIT_SCHED attribute is given,

        initialize the schedpolicy field of new_thread->p_start_args
