1998-07-20 Ben Elliston <bje@cygnus.com> * misc.c (pthread_once): Implement. * pthread.h (_pthread_once_flag): Add new variable. (_pthread_once_lock): Add new mutex lock to ensure integrity of access to _pthread_once_flag. Mon Jul 20 02:31:05 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * private.c (_pthread_getthreadindex): Implement. * pthread.h: Add application static data dependent on _PTHREADS_BUILD_DLL define. This is needed to avoid allocating non-sharable static data within the pthread DLL. * implement.h: Add _pthread_cleanup_stack_t, _pthread_cleanup_node_t and _PTHREAD_HASH_INDEX. * exit.c (pthread_exit): Begin work on cleanup and de-allocate thread-private storage. * create.c (pthread_create): Add thread to thread table. Keep a thread-private copy of the attributes with default values filled in when necessary. Same for the cleanup stack. Make pthread_create C run-time library friendly by using _beginthreadex() instead of CreateThread(). Fix error returns. Sun Jul 19 16:26:23 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * implement.h: Rename pthreads_thread_count to _pthread_threads_count. Create _pthread_threads_thread_t struct to keep thread specific data. * create.c: Rename pthreads_thread_count to _pthread_threads_count. (pthread_create): Handle errors from CreateThread(). 1998-07-19 Ben Elliston <bje@cygnus.com> * condvar.c (pthread_cond_wait): Generalise. Moved from here .. (cond_wait): To here. (pthread_cond_timedwait): Implement; use generalised cond_wait(). * pthread.h (pthread_key_t): Define this type. (pthread_key_create): Add function prototype. (pthread_setspecific): Likewise. (pthread_getspecific): Likwise. (pthread_key_delete): Likewise. * tsd.c (pthread_key_create): Implement. (pthread_setspecific): Likewise. (pthread_getspecific): Likewise. (pthread_key_delete): Likewise. * mutex.c (pthread_mutex_trylock): Return ENOSYS if this function is called on a Win32 platform which is not Windows NT. 1998-07-18 Ben Elliston <bje@cygnus.com> * 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. * pthread.h (pthread_cond_init): Add function protoype. (pthread_cond_broadcast): Likewise. (pthread_cond_signal): Likewise. (pthread_cond_timedwait): Likewise. (pthread_cond_wait): Likewise. (pthread_cond_destroy): Likewise. (pthread_cond_t): Define this type. Fix for u_int. Do not assume that the mutex contained withing the pthread_cond_t structure will be a critical section. Use our new POSIX type! * implement.h (_pthread_condattr_t): Remove shared attribute. 1998-07-17 Ben Elliston <bje@cygnus.com> * pthread.h (PTHREADS_PROCESS_PRIVATE): Remove. (PTHREAD_PROCESS_SHARED): Likewise. No support for mutexes shared across processes for now. (pthread_mutex_t): Use a Win32 CRITICAL_SECTION type for better performance. * implement.h (_pthread_mutexattr_t): Remove shared attribute. * mutex.c (pthread_mutexattr_setpshared): This optional function is no longer supported, since we want to implement POSIX mutex variables using the much more efficient Win32 critical section primitives. Critical section objects in Win32 cannot be shared between processes. (pthread_mutexattr_getpshared): Likewise. (pthread_mutexattr_init): No need to malloc any storage; the attributes structure is now empty. (pthread_mutexattr_destroy): This is now a nop. (pthread_mutex_init): Use InitializeCriticalSection(). (pthread_mutex_destroy): Use DeleteCriticalSection(). (pthread_mutex_lock): Use EnterCriticalSection(). (pthread_mutex_trylock): Use TryEnterCriticalSection(). This is not supported by Windows 9x, but trylock is a hack anyway, IMHO. (pthread_mutex_unlock): Use LeaveCriticalSection(). 1998-07-14 Ben Elliston <bje@cygnus.com> * attr.c (pthread_attr_setstacksize): Implement. (pthread_attr_getstacksize): Likewise. (pthread_attr_setstackaddr): Likewise. (pthread_attr_getstackaddr): Likewise. (pthread_attr_init): Likewise. (pthread_attr_destroy): Likewise. * condvar.c (pthread_condattr_init): Add `_cond' to function name. * mutex.c (pthread_mutex_lock): Add `_mutex' to function name. (pthread_mutex_trylock): Likewise.

(pthread_unlock): Likewise. 1998-07-12 Ben Elliston <bje@cygnus.com> * implement.h (_pthread_mutexattr_t): Define this implementation internal type. Application programmers only see a mutex attribute object as a void pointer. * pthread.h (pthread_mutexattr_t): Define this type. (pthread_mutexattr_init): Add function prototype. (pthread_mutexattr_destroy): Likewise. (pthread_mutexattr_setpshared): Likewise. (pthread_mutexattr_getpshared): Likewise. (pthread_mutexattr_setprotocol): Likewise.
