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_getstacksize): Merge with John Bossom's version. (pthread_attr_setstackaddr): Merge with John Bossom's version. (pthread_attr_getstackaddr): Merge with John Bossom's version. (pthread_attr_init): Merge with John Bossom's version. (pthread_attr_destroy): Merge with John Bossom's version. (pthread_attr_getdetachstate): 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. (pthread_condattr_destroy): Replaced by John Bossom's version. (pthread_condattr_getpshared): Replaced by John Bossom's version. (pthread_condattr_setpshared): Replaced by John Bossom's version.

* dll.c (PthreadsEntryPoint): Cast return value of GetProcAddress to resolve compile warning from MSVC.
1998-12-06As well as patches from Anders, this commit includes some older changesrpj
that hadn't been checked in. Those are to finish off the original TSD management scheme which will now start to be replaced by John Bossom's implementation. Anders' description of his changes:- Fixes the problem with `TryEnterCriticalSection' on w95 systems. Instead of directly calling `TryEnterCriticalSection' it tries to get a pointer at DLL startup and only calls the function if it exists. See ChangeLog for things changed. 1998-12-05 Anders Norlander <anorland@hem2.passagen.se> * implement.h (_pthread_try_enter_critical_section): New extern * dll.c (_pthread_try_enter_critical_section): New pointer to TryEnterCriticalSection if it exists; otherwise NULL. * dll.c (PthreadsEntryPoint): Initialize _pthread_try_enter_critical_section at startup and release kernel32 handle when DLL is being unloaded. * mutex.c (pthread_mutex_trylock): Replaced check for NT with a check if _pthread_try_enter_critical_section is valid pointer to a function. Call _pthread_try_enter_critical_section instead of TryEnterCriticalSection to avoid errors on Win95. Sun Nov 15 21:24:06 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * cleanup.c (_pthread_destructor_run_all): Declare missing void * arg. Fixup CVS merge conflicts. Fri Oct 30 15:15:50 1998 Ross Johnson <rpj@swan.canberra.edu.au> * cleanup.c (_pthread_handler_push): Fixed bug appending new handler to list reported by Peter Slacik <Peter.Slacik@leibinger.freinet.de>. (new_thread): Rename poorly named local variable to "new_handler". Sat Oct 24 18:34:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * global.c: Add TSD key management array and index declarations. * implement.h: Ditto for externs. Fri Oct 23 00:08:09 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * implement.h (_PTHREAD_TSD_KEY_REUSE): Add enum. * private.c (_pthread_delete_thread): Add call to _pthread_destructor_run_all() to clean up the threads keys. * cleanup.c (_pthread_destructor_run_all): Check for no more dirty keys to run destructors on. Assume that the destructor call always succeeds and set the key value to NULL.
