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.

* buildlib.bat: Fix args to CL when building the .DLL * cleanup.c (_pthread_destructor_run_all): Fix TSD key management. This is a tidy-up before TSD and Thread management is completely replaced by John Bossom's much more elegant code. * tsd.c (pthread_key_create): Fix TSD key management. * global.c (_pthread_key_virgin_next): Initialise. * build.bat: New DOS script to compile and link a pthreads app using Microsoft's CL compiler linker. * buildlib.bat: New DOS script to compile all the object files and create pthread.lib and pthread.dll using Microsoft's CL compiler linker.
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.

* 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.

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. (_pthread_handler_pop_all): Fix stack arg type in prototype. * cleanup.c (_pthread_handler_push): Change return type to int and return ENOMEM if malloc() fails.

* 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.

* 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.
