* all: No code changes, just cleanup. - remove #if 0 /* Pre Bossom */ enclosed code. - Remove some redundant #includes. * pthread.h: Update implemented/unimplemented routines list. * Tag the bossom merge branch getting ready to merge back to main trunk.
1998-12-28With this update I'm able to build the library and build and run therpj
tsd1.c test successfully using buildlib.bat and build.bat scripts. I not convinced that I understand the relationships between "__cplusplus" and "_WIN32" and the MS compiler, particularly in pthread.h where pthread_cleanup_push etc is defined. In particular, I have assumed that the __try/__finally blocks are only available if _WIN32 and __cplusplus are defined. I suspect this is wrong. Tue Dec 29 13:11:16 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * implement.h: Move the following struct definitions to pthread.h: pthread_t_, pthread_attr_t_, pthread_mutex_t_, pthread_mutex_t_, pthread_mutexattr_t_, pthread_key_t_, pthread_cond_t_, pthread_condattr_t_, pthread_once_t_. * pthread.h: Add "_" prefix to pthread_push_cleanup and pthread_pop_cleanup internal routines, and associated struct and typedefs. * buildlib.bat: Add compile command for semaphore.c * pthread.def: Comment out pthread_atfork routine name. Now unimplemented. * tsd.c (pthread_setspecific): Rename tkAssocCreate to _pthread_tkAssocCreate. (pthread_key_delete): Rename tkAssocDestroy to _pthread_tkAssocDestroy. * sync.c (pthread_join): Rename threadDestroy to _pthread_threadDestroy * sched.c (is_attr): attr is now **attr (was *attr), so add extra NULL pointer test. (pthread_attr_setschedparam): Increase redirection for attr which is now a **. (pthread_attr_getschedparam): Ditto. (pthread_setschedparam): Change thread validation and rename "thread" Win32 thread Handle element name to match John Bossom's version. (pthread_getschedparam): Ditto. * private.c (_pthread_threadDestroy): Rename call to callUserDestroyRoutines() as _pthread_callUserDestroyRoutines() * misc.c: Add #include "implement.h". * dll.c: Remove defined(KLUDGE) wrapped code. * fork.c: Remove redefinition of ENOMEM. Remove pthread_atfork() and fork() with #if 0/#endif. * create.c (pthread_create): Rename threadStart and threadDestroy calls to _pthread_threadStart and _pthread_threadDestroy. * implement.h: Rename "detachedstate" to "detachstate". * attr.c: Rename "detachedstate" to "detachstate". Mon Dec 28 09:54:39 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * pthread.h (pthread_attr_t_): Change to *pthread_attr_t. * attr.c (pthread_attr_setstacksize): Merge with John Bossom's version.

(pthread_attr_setdetachstate): Merge with John Bossom's version. (is_attr): attr is now **attr (was *attr), so add extra NULL pointer test. * implement.h (pthread_attr_t_): Add and rename elements in JEB's version to correspond to original, so that it can be used with original attr routines. * pthread.h: Add #endif at end which was truncated in merging.

* misc.c (pthreadCancelableWait): New function by John Bossom. Non-stand ard but provides a hook that can be used to implement cancellation points in applications that use this library. * pthread.h (pthread_cleanup_pop): C++ (non-WIN32) version uses try/catch to emulate John Bossom's WIN32 __try/__finally behaviour. In the WIN32 version __finally block, add a test for AbnormalTermination otherwise cleanup is only run if the cleanup_pop execute arg is non-zero. Cancella tion should cause the cleanup to run irrespective of the execute arg. * condvar.c (pthread_condattr_init): Replaced by John Bossom's version.

* misc.c (pthread_once): Use the POSIX mutex primitives, not Win32. Remove irrelevant FIXME comment. * pthread.h (PTHREAD_ONCE_INIT): Define. * tests/once1.c: New file; test for pthread_once(). Passes.
1998-10-041998-10-05 Ben Elliston <bje@cygnus.com>bje
* global.c (PTHREAD_MUTEX_INITIALIZER): Move to pthread.h. * pthread.h (PTHREAD_MUTEX_INITIALIZER): Define. (pthread_mutex_t): Reimplement as a struct containing a valid flag. If the flag is ever down upon entry to a mutex operation, we call pthread_mutex_create() to initialise the object. This fixes the problem of how to handle statically initialised objects that can't call InitializeCriticalSection() due to their context. * mutex.c (pthread_mutex_init): Set valid flag. (pthread_mutex_destroy): Clear valid flag. (pthread_mutex_lock): Check and handle the valid flag. (pthread_mutex_unlock): Likewise. (pthread_mutex_trylock): Likewise. * tests/mutex3.c: New file; test for the static initialisation macro. Passes.

1998-10-031998-10-03 Ben Elliston <bje@cygnus.com>bje
* pthread.h: No need to include <unistd.h>. It doesn't even exist on Win32! Again, an artifact of cross-compilation.
1998-10-031998-10-03 Ben Elliston <bje@cygnus.com>bje
* process.h: Remove. This was a stand-in before we started doing native compilation under Win32. * pthread.h (pthread_mutex_init): Make `attr' argument const.

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.

Not complete. * implement.h (_pthread_threads_thread): Rename, remove thread member, add win32handle and ptstatus members.

This is so we can let the Win32 thread terminate and reuse the HANDLE while pthreads holds it's own thread ID until the last waiting join exits.
