* condvar.c (pthread_cond_destroy): fix bug with respect to deadlock in the case of concurrent _destroy/_unblock; a condition variable can be destroyed immediately after all the threads that are blocked on it are awakened.
2001-07-18Fix potential NULL pointer dereferences.rpj
Contributed by - "Scott McCaskill" <scott@magruder.org> * mutex.c (pthread_mutexattr_init): Return ENOMEM immediately and don't dereference the NULL pointer if calloc fails. (pthread_mutexattr_getpshared): Don't dereference a pointer that is possibly NULL. * barrier.c (pthread_barrierattr_init): Likewise (pthread_barrierattr_getpshared): Don't dereference a pointer that is possibly NULL. * condvar.c (pthread_condattr_getpshared): Don't dereference a pointer that is possibly NULL.
2001-07-08Barriers fixed and tested more extensively.rpj
* barrier.c: Fix several bugs in all routines. Now passes tests/barrier5.c which is fairly rigorous. There is still a non-optimal work-around for a race condition between the barrier breeched event signal and event wait. Basically the last (signalling) thread to hit the barrier yields to allow any other threads, which may have lost the race, to complete. tests/ChangeLog: * barrier3.c: Fixed. * barrier4.c: Fixed. * barrier5.c: New; proves that all threads in the group reaching the barrier wait and then resume together. Repeats the test using groups of 1 to 16 threads. Each group of threads must negotiate a large number of barriers (10000). * spin4.c: Fixed. * test.h (error_string): Modified the success (0) value.
2001-07-06Spinlocks and barriers fixed and working. Beta level.rpj
* spin.c: Revamped and working; included static initialiser. * barrier.c: Likewise. * condvar.c: Macro constant change; inline auto init routine. * mutex.c: Likewise. * rwlock.c: Likewise. * private.c: Add support for spinlock initialiser. * global.c: Likewise. * implement.h: Likewise. * pthread.h (PTHREAD_SPINLOCK_INITIALIZER): Fix typo. tests/ChangeLog: * spin3.c: Changed test and fixed. * spin4.c: Fixed. * barrier3.c: Fixed. * barrier4.c: Fixed.
2001-07-03Undo a minor code change in condvar.c and insert commentsrpj
in instead.

Contributed by - Alexander Terekhov. * condvar.c: Fixed lost signal bug reported by Timur Aydin (taydin@snet.net). [RPJ (me) didn't translate the original algorithm correctly.] * semaphore.c: Added sem_post_multiple; this is a useful routine, but it doesn't appear to be standard. For now it's not an exported function.
2001-06-04 * condvar.c: Add original description of the algorithm asrpj
developed by Terekhov and Thomas, plus reference to README.CV.

* condvar.c (ptw32_cond_wait_cleanup): Ensure that all waking threads check if they are the last, and notify the broadcaster if so - even if an error occurs in the waiter. * semaphore.c (_decrease_semaphore): Should be a call to ptw32_decrease_semaphore. (_increase_semaphore): Should be a call to ptw32_increase_semaphore. * misc.c (ptw32_cancelable_wait): Renamed from CancelableWait. (cond_wait_cleanup*): Rename to ptw32_cond_wait_cleanup*.

* Several: Fix typos from scripted edit session yesterday. * nonportable.c (pthread_mutexattr_setforcecs_np): Moved this function from mutex.c. (pthread_getw32threadhandle_np): New function to return the win32 thread handle that the POSIX thread is using. * mutex.c (pthread_mutexattr_setforcecs_np): Moved to new file "nonportable.c". * pthread.h (PTW32_BUILD): Only redefine __except and catch compiler keywords if we aren't building the library (ie. PTW32_BUILD is not defined) - this is safer than defining and then undefining if not building the library. * implement.h: Remove __except and catch undefines. * Makefile (CFLAGS): Define PTW32_BUILD. * GNUmakefile (CFLAGS): Define PTW32_BUILD. * All appropriate: Change Pthread_exception* to ptw32_exception* to be consistent with internal identifier naming. * private.c (ptw32_throw): New function to provide a generic exception throw for all internal exceptions and EH schemes. (ptw32_threadStart): pthread_exit() value is now returned via the thread structure exitStatus element. * exit.c (pthread_exit): pthread_exit() value is now returned via the thread structure exitStatus element. * cancel.c (ptw32_cancel_self): Now uses ptw32_throw. (pthread_setcancelstate): Ditto. (pthread_setcanceltype): Ditto. (pthread_testcancel): Ditto. (pthread_cancel): Ditto. * misc.c (CancelableWait): Ditto. * exit.c (pthread_exit): Ditto. * All applicable: Change PTW32_ prefix to PTW32_ prefix to remove leading underscores from private library identifiers.

* All applicable: Change _pthread_ prefix to ptw32_ prefix to remove leading underscores from private library identifiers (single and double leading underscores are reserved in the ANSI C standard for compiler implementations).

* sched.c (sched_get_priority_max): Handle different WinCE and Win32 priority values together. (sched_get_priority_min): Ditto. - Tristan Savatier <tristan@mpegtv.com> * create.c (pthread_create): Force new threads to wait until pthread_create has the new thread's handle; we also retain a local copy of the handle for internal use until pthread_create returns. * private.c (_pthread_threadStart): Initialise ei[]. (_pthread_threadStart): When beginthread is used to start the thread, force waiting until the creator thread had the thread handle. * cancel.c (_pthread_cancel_thread): Include context switch code for defined(_X86_) environments in addition to _M_IX86. * rwlock.c (pthread_rwlock_destroy): Assignment changed to avoid compiler warning. * private.c (_pthread_get_exception_services_code): Cast NULL return value to avoid compiler warning. * cleanup.c (pthread_pop_cleanup): Initialise "cleanup" variable to avoid compiler warnings. * misc.c (_pthread_new): Change "new" variable to "t" to avoid confusion with the C++ keyword of the same name. * condvar.c (cond_wait_cleanup): Initialise lastWaiter variable. (cond_timedwait): Remove unused local variables. to avoid compiler warnings. * dll.c (dllMain): Remove 2000-07-21 change - problem appears to be in pthread_create(). 2000-07-22 Ross Johnson <rpj@special.ise.canberra.edu.au> * tsd.c (pthread_key_create): If a destructor was given and the pthread_mutex_init failed, then would try to reference a NULL pointer (*key); eliminate this section of code by using a dynamically initialised mutex (PTHREAD_MUTEX_INITIALIZER). * tsd.c (pthread_setspecific): Return an error if unable to set the value; simplify cryptic conditional. * tsd.c (pthread_key_delete): Locking threadsLock relied on mutex_lock returning an error if the key has no destructor. ThreadsLock is only initialised if the key has a destructor. Making this mutex a static could reduce the number of mutexes used by an application since it is actually created only at first use and it's often destroyed soon after. 2000-07-22 Ross Johnson <rpj@special.ise.canberra.edu.au> * FAQ: Added Q5 and Q6. tests/ChangeLog: 2000-07-25 Ross Johnson <rpj@special.ise.canberra.edu.au> * runtest.bat: modified to work under W98. * runall.bat: Add new tests; modified to work under W98. It was ok under NT. * Makefile: Add new tests. * exception1.c: New; Test passing exceptions back to the application and retaining library internal exceptions. * join0.c: New; Test a single join.

* misc.c (CancelableWait): Ensure cancelEvent handle is the lowest indexed element in the handles array. Enhance test for abandoned objects. * pthread.h (PTHREAD_MUTEX_INITIALIZER): Trailing elements not initialised are set to zero by the compiler. This avoids the problem of initialising the opaque critical section element in it. (PTHREAD_COND_INITIALIZER): Ditto. * semaphore.c (_pthread_sem_timedwait): Check sem == NULL earlier. Sun Mar 7 12:31:14 1999 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * condvar.c (pthread_cond_init): set semaphore initial value to 0, not 1. cond_timedwait was returning signaled immediately. * misc.c (CancelableWait): Place the cancel event handle first in the handle table for WaitForMultipleObjects. This ensures that the cancel event is recognised and acted apon if both objects happen to be signaled together. * private.c (_pthread_cond_test_init_lock): Initialise and destroy. * implement.h (_pthread_cond_test_init_lock): Add extern. * global.c (_pthread_cond_test_init_lock): Add declaration. * condvar.c (pthread_cond_destroy): check for valid initialised CV; flag destroyed CVs as invalid. (pthread_cond_init): pthread_cond_t is no longer just a pointer. This is because PTHREAD_COND_INITIALIZER needs state info to reside in pthread_cond_t so that it can initialise on first use. Will work on making pthread_cond_t (and other objects like it) opaque again, if possible, later. (cond_timedwait): add check for statically initialisation of CV; initialise on first use. (pthread_cond_signal): check for valid CV. (pthread_cond_broadcast): check for valid CV. (_cond_check_need_init): Add. * pthread.h (PTHREAD_COND_INITIALIZER): Fix. (pthread_cond_t): no longer a pointer to pthread_cond_t_.

This is essentially pthread_cond_wait() renamed and modified to add the 'abstime' arg and call the new _pthread_sem_timedwait() instead of sem_wait(). (pthread_cond_wait): Now just calls the internal static function cond_timedwait() with an INFINITE wait. (pthread_cond_timedwait): Now implemented. Calls the internal static function cond_timedwait(). * implement.h (_pthread_sem_timedwait): New internal function prototype. * misc.c (pthreadCancelableWait): Added new 'abstime' argument to allow shorter than INFINITE wait. * semaphore.c (_pthread_sem_timedwait): New function for internal use.

This should be returned by pthread_cond_timedwait which is not implemented yet as of snapshot-1999-01-04-1305. It was implemented in the older version. The Microsoft compiler pragmas probably are more appropriately protected by _MSC_VER than by _WIN32. - Tor Lillqvist <tml@iki.fi>. * pthread.def: pthread_mutex_destroy was missing from the def file - Tor Lillqvist <tml@iki.fi>. * condvar.c (pthread_cond_broadcast): Ensure we only wait on threads if there were any waiting on the condition. I think pthread_cond_broadcast should do the WaitForSingleObject only if cv->waiters > 0? Otherwise it seems to hang, at least in the testg thread program from glib. - Tor Lillqvist <tml@iki.fi>. * semaphore.c (sem_post): Correct typo in comment.

1998-10-061998-10-06 Ben Elliston <bje@cygnus.com>bje
* condvar.c (cond_wait): Use POSIX, not Win32 mutex calls. (pthread_cond_broadcast): Likewise. (pthread_cond_signal): Likewise.

* implement.h(_pthread_virgins): Add extern. (_pthread_virgin_next): Ditto. (_pthread_reuse): Ditto. (_pthread_reuse_top): Ditto. (_pthread_win32handle_map): Ditto. (_pthread_threads_mutex_table): Ditto. * global.c (_pthread_virgins): Changed from array to pointer. Storage allocation for the array moved into dll.c. (_pthread_reuse): Ditto. (_pthread_win32handle_map): Ditto. (_pthread_threads_mutex_table): Ditto. * dll.c (PthreadsEntryPoint): Set up thread admin storage when DLL is loaded. * fork.c (pthread_atfork): Fix function pointer arg to all _pthread_handler_push() calls. Change "arg" arg to NULL in child push. * exit.c: Add windows.h and process.h includes. (_pthread_exit): Add local detachstate declaration. (_pthread_exit): Fix incorrect name for pthread_attr_getdetachstate(). * pthread.h (_POSIX_THREAD_ATTR_STACKSIZE): Move from global.c (_POSIX_THREAD_ATTR_STACKADDR): Ditto. * create.c (pthread_create): Fix #if should be #ifdef. (_pthread_start_call): Remove usused variables. * process.h: Create. * windows.h: Move _beginthreadex and _endthreadex into process.h Mon Aug 3 21:19:57 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * condvar.c (pthread_cond_init): Add NULL attr to pthread_mutex_init() call - default attributes will be used. (cond_wait): Fix typo. (cond_wait): Fix typo - cv was ev. (pthread_cond_broadcast): Fix two identical typos. * cleanup.c (_pthread_destructor_pop_all): Remove _ prefix from PTHREAD_DESTRUCTOR_ITERATIONS. * pthread.h: Move _POSIX_* values into posix.h * pthread.h: Fix typo in pthread_mutex_init() prototype. * attr.c (pthread_attr_init): Fix error in priority member init. * windows.h (THREAD_PRIORITY_NORMAL): Add. * pthread.h (sched_param): Add missing ';' to struct definition. * attr.c (pthread_attr_init): Remove obsolete pthread_attr_t member initialisation - cancelstate, canceltype, cancel_pending. (is_attr): Make arg "attr" a const. * implement.h (_PTHREAD_HANDLER_POP_LIFO): Remove definition. (_PTHREAD_HANDLER_POP_FIFO): Ditto. (_PTHREAD_VALID): Add missing newline escape (\). (_pthread_handler_node): Make element "next" a pointer.

* Makefile (SRCS): Create. Preliminary. * windows.h: Create. Contains Win32 definitions for compile testing. This is just a standin for the real one. * pthread.h (SIG_UNBLOCK): Fix typo. Was SIG_BLOCK. (windows.h): Add include. Required for CRITICAL_SECTION. (pthread_cond_t): Move enum declaration outside of struct definition. (unistd.h): Add include - may be temporary. * condvar.c (windows.h): Add include.

* condvar.c (cond_wait): Add cancelation point. This applies the point to both pthread_cond_wait() and pthread_cond_timedwait(). * exit.c (pthread_exit): Rename "this" to "us". * implement.h: Add comment. * sync.c (pthread_join): I've satisfied myself that pthread_detach() does set the detached attribute in the thread entry attributes to PTHREAD_CREATE_DETACHED. "if" conditions were changed to test that attribute instead of a separate flag. * create.c (pthread_create): Rename "this" to "us". (pthread_create): cancelstate and canceltype are not attributes so the copy to thread entry attribute storage was removed. Only the thread itself can change it's cancelstate or canceltype, ie. the thread must exist already.

* condvar.c (pthread_cond_wait): Generalise. Moved from here .. (cond_wait): To here. (pthread_cond_timedwait): Implement; use generalised cond_wait().
1998-07-171998-07-18 Ben Elliston <bje@cygnus.com>bje
* condvar.c (pthread_condattr_init): Do not attempt to malloc any storage; none is needed now that condattr_t is an empty struct. (pthread_condattr_destory): Likewise; do not free storage. (pthread_condattr_setpshared): No longer supported; return ENOSYS. (pthread_condattr_getpshared): Likewise. (pthread_cond_init): Implement with help from Douglas Schmidt. Remember to initialise the cv's internal mutex. (pthread_cond_wait): Likewise. (pthread_cond_signal): Likewise. (pthread_cond_broadcast): Likewise. (pthread_cond_timedwait): Preliminary implementation, but I need to see some API documentation for `WaitForMultipleObject'. (pthread_destory): Implement.
