* implement.h: Compile-time switch for CYGWIN derived environments to use CreateThread instead of _beginthreadex. Ditto for ExitThread. Patch provided by Anders Norlander <anorland@hem2.passagen.se>.
1999-01-04Parts of this package are going to have to be C++ in the GNU world because werpj
now use exception handling to implement thread cancellation. The MSC compiler appears to know about __try/__except blocks, but gcc (ie. the GNU ANSI C compiler) doesn't know about the equivalent C++ try/catch blocks. This should not be a problem since gcc and g++ are nearly always available together. Some file names may need to change in the CVS repository however. Tue Jan 5 16:33:04 1999 Ross Johnson <rpj@swan.canberra.edu.au> * cleanup.c (_pthread_pop_cleanup): Add C++ version of __try/__except block. Move trailing "}" out of #ifdef _WIN32 block left there by (my) mistake. * private.c: Remove #include <errno.h> which is included by pthread.h.
1999-01-03Merge John Bossom's code into the main trunk. See ChangeLog for details.snapshot-1999-01-04-1305rpj

* 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.
1998-10-291998-10-30 Ben Elliston <bje@cygnus.com>bje
* condvar.c (cond_wait): Fix semantic error. Test for equality instead of making an assignment.

* global.c (PTHREAD_MUTEX_INITIALIZER): Move to pthread.h. * pthread.h (PTHREAD_MUTEX_INITIALIZER): Define. (pthread_mutex_t): Reimplement as a struct containing a valid flag. If the flag is ever down upon entry to a mutex operation, we call pthread_mutex_create() to initialise the object.
