* mutex.c (pthread_mutexattr_setpshared): Not supported; remove. (pthread_mutexattr_getpshared): Likewise. * pthread.h (pthread_mutexattr_setpshared): Remove prototype. (pthread_mutexattr_getpshared): Likewise.
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* sync.c: Rename all instances of _pthread_count_mutex to _pthread_table_mutex. * implement.h: Rename _pthread_count_mutex to _pthread_table_mutex. * global.c: Rename _pthread_count_mutex to _pthread_table_mutex. * create.c (pthread_create): Add critical sections. (_pthread_start_call): Rename _pthread_count_mutex to _pthread_table_mutex.
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* cancel.c (pthread_setcancelstate): Fix indirection bug and rename "this" to "us".
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* signal.c (pthread_sigmask): Rename "this" to "us" and fix some minor syntax errors. Declare "us" and initialise it. * sync.c (pthread_detach): Rename "this" to "target".
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* pthread.h: Converting PTHREAD_* defines to alias the (const int) values in global.c. * global.c: Started converting PTHREAD_* defines to (const int) as a part of making the eventual pthreads DLL binary compatible through version changes.
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* condvar.c (cond_wait): Add cancelation point. This applies the point to both pthread_cond_wait() and pthread_cond_timedwait(). * exit.c (pthread_exit): Rename "this" to "us". * implement.h: Add comment. * sync.c (pthread_join): I've satisfied myself that pthread_detach() does set the detached attribute in the thread entry attributes to PTHREAD_CREATE_DETACHED. "if" conditions were changed to test that attribute instead of a separate flag. * create.c (pthread_create): Rename "this" to "us". (pthread_create): cancelstate and canceltype are not attributes so the copy to thread entry attribute storage was removed. Only the thread itself can change it's cancelstate or canceltype, ie. the thread must exist already.
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* 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.

* fork.c (pthread_atfork): Add all the necessary push calls. Local implementation semantics: If we get an ENOMEM at any time then ALL handlers (including those from previous pthread_atfork() calls) will be popped off each of the three atfork stacks before we return. (fork): Add all the necessary pop calls. Add the thread cancellation and join calls to the child fork. Add #includes. * implement.h: (_pthread_handler_push): Fix return type and stack arg type in prototype. (_pthread_handler_pop): Fix stack arg type in prototype.

1998-07-24 * sync.c (pthread_join): Save valueptr arg in joinvalueptr forrpj
pthread_exit() to use. * private.c (_pthread_new_thread_entry): Initialise joinvalueptr to NULL. * create.c (_pthread_start_call): Rewrite to facilitate joins. pthread_exit() will do a longjmp() back to here. Does appropriate cleanup and exit/return from the thread. (pthread_create): _beginthreadex() now passes a pointer to our thread table entry instead of just the call member of that entry. * implement.h (_pthread_threads_thread): New member void ** joinvalueptr. (_pthread_call_t): New member jmpbuf env. * exit.c (pthread_exit): Major rewrite to handle joins and handing value pointer to joining thread. Uses longjmp() back to _pthread_start_call().

* create.c (pthread_create): Arg to _pthread_new_thread_entry() changed. See next entry. Move mutex locks out. Changes made yesterday and today allow us to start the new thread running rather than temporarily suspended. * private.c (_pthread_new_thread_entry): _pthread_thread_table was changed back to a table of thread structures rather than pointers. As such we're trading storage for increaded speed. This routine was modified to work with the new table. Mutex lock put in around global data accesses.

* 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.
