|
Timer nodes are now reference counted, and can be marked
|
|
as deleted. This allows for the safe release of the global mutex
|
|
in the middle without losing the timer being operated on.
|
|
|
|
* sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
|
|
member is now an enum with three values, so that an intermediate
|
|
state can be represented (deleted but not free for reuse yet).
|
|
New refcount member added.
|
|
* sysdeps/pthread/timer_routines.c: Likewise.

* sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
|
|
timer_addref to ensure that timer won't be deleted while mutex is not

|
|
|
|
A few optimizations. Got rid of unnecessary wakeups of timer threads,
|
|
tightened up some critical regions and micro-optimized some list
|
|
manipulation code.
|
|
|
|
* sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
|
|
Returns int value now to indicate whether timer was queued at head.
|
|
* sysdeps/pthread/posix-timer.h: Likewise.
|
|
* sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of

|
new return value from __timer_thread_queue_timer to avoid waking
|
|
up timer thread unnecessarily.
|
|
|
|
* sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
|
|
inuse flag, because this requires mutex to be held. Callers updated
|
|
to do the check when they have the mutex.
|
|
* sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
|
|
|
|
* sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
|
|
regions: avoids making system calls while holding timer mutex, and
|
|
a few computations were moved outside of the mutex as well.
|
|
* sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
|
|
|
|
* sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
|
|
to list_unlink_ip, meaning idempotent. Pointer manipulation
|
|
changed to get better better code out of gcc.
|
|
* sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
|
|
version of list_unlink added here.
|
|
* sysdeps/pthread/timer_delete.c: Use appropriate list unlink
|
|
function in all places: idempotent one for timers, non-idempotent

one for thread nodes.

|
|
|
|
* sysdeps/pthread/timer_create.c: Thread matching now done on
|
|
clock type as well as thread attributes.
|
|
There are individual global signal-delivering threads for

|
different clock types.

deallocation function now remembers to put thread on active
|
|
list and remove from active list.
|
|
Thus now the feature of binding multiple timers
|
|
to a single thread actually works.

Added missing fork time handling of global libio lock.
|
|
|
|
* lockfile.c (__fresetlockfiles): Now also resets the list lock,
|
|
not just the individual stream locks. Rewritten to use new
|
|
iterator interface provided by libio rather than accessing
|
|
global variable.
|
|
|
|

|
|
which lock and unlock the stream list using the new interface
|
|
provied by libio.
|
|
* internals.h: Likewise.
|
|
|
|
* ptfork.c (__fork): Now calls __flockfilelist before fork,
|
|
and __funlockfilelist in the parent after the fork.
|
|
Child still calls __fresetlockfiles as before.
|
|
|
|
* linuxthreads.texi: Now explains what happens to streams at

fork time. Also whole new section on forking and thread added.

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

2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
|
|
|
|
* mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
|
|
object state is represented with additional bits which distinguish
|
|
whether that state was set up in the current process, or
|
|
in an ancestor process. If that state was set in an ancestor,
|
|
it means that a fork happened while thread was executing the init
|
|
function. In that case, the state is reset to NEVER.
|
|
* mutex.c (__pthread_once_fork_prepare): New function.

2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
|
|
|
|
* internals.h: New thread manager request type, REQ_KICK.
|
|
* join.c (pthread_exit): main thread now calls exit() instead
|
|
of _exit() in order to proper process cleanup.
|
|
* manager.c (__pthread_manager): Do not terminate manager
|
|
after unblocking main thread; wait for main thread's
|
|
REQ_PROCESS_EXIT request instead.
|
|
Also, added REQ_KICK case to handle new request; this just does
|
|
nothing.
|
|
* manager.c (pthread_exited): Do not terminate manager after
|
|
unblocking main thread.
|
|
* manager.c (__pthread_manager_sighandler): If the main thread
|
|
is waiting for all other threads to die, send a REQ_KICK into
|
|
the thread manager request pipe to get it to clean out the threads
|
|
and unblock the main thread as soon as possible. This fixes
|
|
the 2000 millisecond hang on shutdown bug.
|
|
* Examples/ex7.c: New file, tests shutdown behavior when all threads
|
|
including the main one call pthread_exit(), or implicitly do so.
|
|
* Makefile (tests): Add ex7.

|
|
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.

Since sigset_t no longer fits in a register, we can't pass in the
|
|
thread's initial mask so easily. Take this opportunity to simplify
|
|
the clone implementation by only accepting a single void* argument.

|
|
* linuxthreads/manager.c (__pthread_manager): Put thread vitals
|
|
in the thread struct instead of as arguments through clone.
|
|
(pthread_start_thread): Look for them there.
|
|
* linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
|
|
p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
|
|
* linuxthreads/pthread.c (pthread_initialize_manager): Revise
|
|
clone invocation.
