* 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.

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.

* attr.c, implement.h, pthread.h, ChangeLog: Resolve CVS merge conflicts. * private.c (_pthread_find_thread_entry): Changes to return type to support leaner _pthread_threads_table[] which now only stores _pthread_thread_thread_t *. (_pthread_new_thread_entry): Internal changes. (_pthread_delete_thread_entry): Internal changes to avoid contention. Calling routines changed accordingly. * pthread.h: Modified cleanup macros to use new generic push and pop. Added destructor and atfork stacks to _pthread_threads_thread_t. * cleanup.c (_pthread_handler_push, _pthread_handler_pop, _pthread_handler_pop_all): Renamed cleanup push and pop routines and made generic to handle destructors and atfork handlers as well. * create.c (_pthread_start_call): New function is a wrapper for all new threads. It allows us to do some cleanup when the thread returns, ie. that is otherwise only done if the thread is cancelled. * exit.c (_pthread_vacuum): New function contains code from pthread_exit() that we need in the new _pthread_start_call() as well. * implement.h: Various additions and minor changes. * pthread.h: Various additions and minor changes. Change cleanup handler macros to use generic handler push and pop functions. * attr.c: Minor mods to all functions. (is_attr): Implemented missing function. * create.c (pthread_create): More clean up. * private.c (_pthread_find_thread_entry): Implement. (_pthread_delete_thread_entry): Implement. (_pthread_new_thread_entry): Implement. These functions manipulate the implementations internal thread table and are part of general code cleanup and modularisation. They replace _pthread_getthreadindex() which was removed. * exit.c (pthread_exit): Changed to use the new code above. * pthread.h: Add cancelability constants. Update comments.

There was little gain in hiding these details. (_pthread_condattr_t): Likewise.
