* condvar.c (pthread_cond_destroy): Add critical section.
(cond_timedwait): Add critical section; check for timeout
waiting on semaphore.
(pthread_cond_broadcast): Add critical section.

The following changes fix a bug identified by
Lorin Hochstein <lmh@xiphos.ca> and solved by
John Bossom <John.Bossom@Cognos.COM>.
The problem was that cleanup handlers were not executed when
pthread_exit() was called.
* implement.h (pthread_t_): Add exceptionInformation element for
C++ per-thread exception information.
(general): Define and rename exceptions.
* misc.c (CancelableWait): _PTHREAD_EPS_CANCEL (SEH) and
Pthread_exception_cancel (C++) used to identify the exception.
* cancel.c (pthread_testcancel): _PTHREAD_EPS_CANCEL (SEH) and
Pthread_exception_cancel (C++) used to identify the exception.
* exit.c (pthread_exit): throw/raise an exception to return to
_pthread_threadStart() to exit the thread. _PTHREAD_EPS_EXIT (SEH)
and Pthread_exception_exit (C++) used to identify the exception.
* private.c (_pthread_threadStart): Add pthread_exit exception trap;
clean up and exit the thread directly rather than via pthread_exit().

* misc.c (CancelableWait): Initialise exceptionInformation[2].
(pthread_self): Get a real Win32 thread handle for implicit threads.
* cancel.c (pthread_testcancel): Initialise exceptionInformation[2].
* implement.h (SE_INFORMATION): Fix values.
* private.c (_pthread_threadDestroy): Close the thread handle.

* semaphore.c (sem_wait): Remove second arg to
pthreadCancelableWait() call.
Fri Jan 22 14:31:59 1999 Ross Johnson <rpj@swan.canberra.edu.au>
* Makefile.in (CFLAGS): Remove -fhandle-exceptions. Not needed
with egcs. Add -g for debugging.
* create.c (pthread_create): Replace __stdcall with PT_STDCALL
macro. This is a hack and must be fixed.
* misc.c (CancelableWait): Remove redundant statement.
* mutex.c (pthread_mutexattr_init): Cast calloc return value.
* misc.c (CancelableWait): Add cast.
(pthread_self): Add cast.
* exit.c (pthread_exit): Add cast.
* condvar.c (pthread_condattr_init): Cast calloc return value.
* cleanup.c: Reorganise conditional compilation.
* attr.c (pthread_attr_init): Remove unused 'result'.
Cast malloc return value.
* private.c (_pthread_callUserDestroyRoutines): Redo conditional
compilation.
* misc.c (CancelableWait): C++ version uses 'throw'.
* cancel.c (pthread_testcancel): Ditto.
* implement.h (class pthread_exception): Define for C++.
* pthread.h: Fix C, C++, and Win32 SEH condition compilation
mayhem around pthread_cleanup_* defines. C++ version now uses John
Bossom's cleanup handlers.
(pthread_attr_t): Make 'valid' unsigned.
Define '_timeb' as 'timeb' for Ming32.
Define PT_STDCALL as nothing for Mingw32. May be temporary.
* cancel.c (pthread_testcancel): Cast return value.

* {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.
|
|
* 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.
|
|
* cancel.c (pthread_setcancelstate): Fix indirection bug and rename
"this" to "us".
|
|
* 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.
