* {most}.c: Include <errno.h> to get POSIX error values. * signal.c (pthread_sigmask): Only provide if HAVE_SIGSET_T is defined. * config.h: #undef features, don't #define them. This will be generated by autoconf very soon.

* sync.c (pthread_join): Remove target_thread_mutex and it's initialisation. Rename getdetachedstate to getdetachstate. Remove unused variable "exitcode". (pthread_detach): Remove target_thread_mutex and it's initialisation. Rename getdetachedstate to getdetachstate. Rename setdetachedstate to setdetachstate.

* implement.h: Add _PTHREAD_VALID macro. * sync.c (pthread_join): Modify to use the new thread type and _pthread_delete_thread(). Rename "target" to "thread". Remove extra local variable "target". (pthread_detach): Ditto. * signal.c (pthread_sigmask): Move init of "us" out of inner block. Fix instance of "this" should have been "us". Rename "us" to "thread". * sched.c (pthread_setschedparam): Modify to use the new thread type. (pthread_getschedparam): Ditto. * private.c (_pthread_find_thread): Fix return type and arg. * implement.h: Remove _PTHREAD_YES and _PTHREAD_NO. (_pthread_new_thread): Add prototype. (_pthread_find_thread): Ditto. (_pthread_delete_thread): Ditto. (_pthread_new_thread_entry): Remove prototype. (_pthread_find_thread_entry): Ditto. (_pthread_delete_thread_entry): Ditto. ( _PTHREAD_NEW, _PTHREAD_INUSE, _PTHREAD_EXITED, _PTHREAD_REUSE): Add. * create.c (pthread_create): Minor rename "us" to "new" (I need these cues but it doesn't stop me coming out with some major bugs at times). Load start_routine and arg into the thread so the wrapper can call it. * exit.c (pthread_exit): Fix pthread_this should be pthread_self. * cancel.c (pthread_setcancelstate): Change _pthread_threads_thread_t * to pthread_t and init with pthread_this(). (pthread_setcanceltype): Ditto.

* sync.c: Rename all instances of _pthread_count_mutex to _pthread_table_mutex. * implement.h: Rename _pthread_count_mutex to _pthread_table_mutex. * global.c: Rename _pthread_count_mutex to _pthread_table_mutex. * create.c (pthread_create): Add critical sections. (_pthread_start_call): Rename _pthread_count_mutex to _pthread_table_mutex.

* signal.c (pthread_sigmask): Rename "this" to "us" and fix some minor syntax errors. Declare "us" and initialise it. * sync.c (pthread_detach): Rename "this" to "target".

* 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.

* private.c (_pthread_delete_thread_entry): Mutex locks removed. Mutexes must be applied at the caller level. (_pthread_new_thread_entry): Ditto. (_pthread_new_thread_entry): Init cancelstate, canceltype, and cancel_pending to default values. (_pthread_new_thread_entry): Rename "this" to "new". (_pthread_find_thread_entry): Rename "this" to "entry". (_pthread_delete_thread_entry): Rename "thread_entry" to "entry". * create.c (_pthread_start_call): Mutexes changed to _pthread_count_mutex. All access to the threads table entries is under the one mutex. Otherwise chaos reigns. Sat Jul 25 23:16:51 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * implement.h (_pthread_threads_thread): Move cancelstate and canceltype members out of pthread_attr_t into here.
1998-07-25Sat Jul 25 00:00:13 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* create.c (_pthread_start_call): Set thread priority. Ensure our thread entry is removed from the thread table but only if pthread_detach() was called and there are no waiting joins. (pthread_create): Set detach flag in thread entry if the thread is created PTHREAD_CREATE_DETACHED. * pthread.h (pthread_attr_t): Rename member "detachedstate". * attr.c (pthread_attr_init): Rename attr members. * exit.c (pthread_exit): Fix indirection mistake. * implement.h (_PTHREAD_THREADS_TABLE_INDEX): Add. * exit.c (_pthread_vacuum): Fix incorrect args to _pthread_handler_pop_all() calls. Make thread entry removal conditional. * sync.c (pthread_join): Add multiple join and async detach handling. * implement.h (_PTHREAD_THREADS_TABLE_INDEX): Add. * global.c (_pthread_threads_mutex_table): Add. * implement.h (_pthread_once_flag): Remove. (_pthread_once_lock): Ditto. (_pthread_threads_mutex_table): Add. * global.c (_pthread_once_flag): Remove. (_pthread_once_lock): Ditto. * sync.c (pthread_join): Fix tests involving new return value from _pthread_find_thread_entry(). (pthread_detach): Ditto. * private.c (_pthread_find_thread_entry): Failure return code changed from -1 to NULL.

* sync.c (pthread_detach): Use equality test, not assignment. * create.c (_pthread_start_call): Add call to Win32 CloseHandle() if thread is detached.
1998-07-241998-07-24 Ben Elliston <bje@cygnus.com>bje
* sync.c (pthread_detach): Close the Win32 thread handle to emulate detached (or daemon) threads.
1998-07-24 * sync.c (pthread_join): Save valueptr arg in joinvalueptr forrpj
pthread_exit() to use. * private.c (_pthread_new_thread_entry): Initialise joinvalueptr to NULL. * create.c (_pthread_start_call): Rewrite to facilitate joins. pthread_exit() will do a longjmp() back to here. Does appropriate cleanup and exit/return from the thread. (pthread_create): _beginthreadex() now passes a pointer to our thread table entry instead of just the call member of that entry. * implement.h (_pthread_threads_thread): New member void ** joinvalueptr. (_pthread_call_t): New member jmpbuf env. * exit.c (pthread_exit): Major rewrite to handle joins and handing value pointer to joining thread. Uses longjmp() back to _pthread_start_call().
