1998-07-23 * global.c: New. Global data objects declared here. These moved fromrpj
pthread.h. * pthread.h: Move implementation hidden definitions into implement.h. * implement.h: Move implementation hidden definitions from pthread.h. Add constants to index into the different handler stacks. * cleanup.c (_pthread_handler_push): Simplify args. Restructure. (_pthread_handler_pop): Simplify args. Restructure. (_pthread_handler_pop_all): Simplify args. Restructure.

* 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.

* implement.h (_pthread_attr_t): Moved to a public definition in pthread.h. There was little gain in hiding these details.

* attr.c (pthread_setstacksize): Update test of attr argument. (pthread_getstacksize): Likewise. (pthread_setstackaddr): Likewise. (pthread_getstackaddr): Likewise. (pthread_attr_init): No need to allocate any storage. (pthread_attr_destroy): No need to free any storage. * mutex.c (is_attr): Not likely to be needed; remove. (remove_attr): Likewise. (insert_attr): Likewise. * pthread.h (pthread_attr_t): Moved here from implement.h. * implement.h (_pthread_mutexattr_t): Moved to a public definition in pthread.h. There was little gain in hiding these details. (_pthread_condattr_t): Likewise.

* cleanup.c (_pthread_cleanup_push): Implement. (_pthread_cleanup_pop): Implement. (_pthread_do_cancellation): Implement. These are private to the implementation. The real cleanup functions are macros. See below. * pthread.h (pthread_cleanup_push): Implement as a macro. (pthread_cleanup_pop): Implement as a macro. Because these are macros which start and end a block, the POSIX scoping requirement is observed. See the comment in the file. * exit.c (pthread_exit): Refine the code. * create.c (pthread_create): Code cleanup. * implement.h (RND_SIZEOF): Add RND_SIZEOF(T) to round sizeof(T) up to multiple of DWORD. Add function prototypes. * private.c (_pthread_getthreadindex): "*thread" should have been "thread". Detect empty slot fail condition.

* private.c (_pthread_getthreadindex): Implement. * pthread.h: Add application static data dependent on _PTHREADS_BUILD_DLL define. This is needed to avoid allocating non-sharable static data within the pthread DLL. * implement.h: Add _pthread_cleanup_stack_t, _pthread_cleanup_node_t and _PTHREAD_HASH_INDEX. * exit.c (pthread_exit): Begin work on cleanup and de-allocate thread-private storage. * create.c (pthread_create): Add thread to thread table. Keep a thread-private copy of the attributes with default values filled in when necessary. Same for the cleanup stack. Make pthread_create C run-time library friendly by using _beginthreadex() instead of CreateThread(). Fix error returns. Sun Jul 19 16:26:23 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * implement.h: Rename pthreads_thread_count to _pthread_threads_count. Create _pthread_threads_thread_t struct to keep thread specific data. * create.c: Rename pthreads_thread_count to _pthread_threads_count. (pthread_create): Handle errors from CreateThread().

* implement.h (PTHREADS_THREADS_MAX): Remove trailing semicolon. (PTHREADS_STACK_MIN): Specify; needs confirming. (_pthreads_attr_t): Define this type. (_pthreads_condattr_t): Likewise.

* implement.h (_pthread_mutex_attr_t): Define this implementation internal type. Application programmers only see a mutex attribute object as a void pointer.
