2002-03-02 * errno.c: Compiler directive was incorrectly including code.rpj
* pthread.h: Conditionally added some #defines from config.h needed when not building the library. e.g. NEED_ERRNO, NEED_SEM. (PTW32_DLLPORT): Now only defined if _DLL defined. (_errno): Compiler directive was incorrectly including prototype. * sched.h: Conditionally added some #defines from config.h needed when not building the library. * semaphore.h: Replace an instance of NEED_SEM that should have been NEED_ERRNO. This change currently has nil effect. * GNUmakefile: Correct some recent changes. * Makefile: Add rule to generate pre-processor output.
2002-02-23 * pthread_cond_destroy.c: Expand the time changerpj
critical section to solve deadlock problem. * pthread.c: Add all remaining C modules. * pthread.h: Use dllexport/dllimport attributes on functions to avoid using pthread.def. * sched.h: Likewise. * semaphore.h: Likewise. * GNUmakefile: Add new targets for single translation unit build to maximise inlining potential; generate pthread.def automatically. * Makefile: Likewise, but no longer uses pthread.def.

* mutex.c (pthread_mutex_timedlock): New function suggested by Alexander Terekhov. The logic required to implement this properly came from Alexander, with some collaboration with Thomas Pfaff. (pthread_mutex_unlock): Wrap the waiters check and sema post in a critical section to prevent a race with pthread_mutex_timedlock. (ptw32_timed_semwait): New function; returns a special result if the absolute timeout parameter represents a time already passed when called; used by pthread_mutex_timedwait(). Have deliberately not reused the name "ptw32_sem_timedwait" because they are not the same routine. * condvar.c (ptw32_cond_timedwait): Use the new sem_timedwait() instead of ptw32_sem_timedwait(), which now has a different function. See previous. * implement.h: Remove prototype for ptw32_sem_timedwait. See next. (pthread_mutex_t_): Add critical section element for access to lock_idx during mutex post-timeout processing. * semaphore.h (sem_timedwait): See next. * semaphore.c (sem_timedwait): See next. * private.c (ptw32_sem_timedwait): Move to semaphore.c and rename as sem_timedwait(). 2002-01-18 Ross Johnson <rpj@special.ise.canberra.edu.au> * sync.c (pthread_join): Was getting the exit code from the calling thread rather than the joined thread if defined(__MINGW32__) && !defined(__MSVCRT__). 2002-01-15 Ross Johnson <rpj@special.ise.canberra.edu.au> * pthread.h: Unless the build explicitly defines __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then the build defaults to __CLEANUP_C style cleanup. This style uses setjmp/longjmp in the cancelation and thread exit implementations and therefore won't do stack unwinding if linked to applications that have it (e.g. C++ apps). This is currently consistent with most/all commercial Unix POSIX threads implementations. * spin.c (pthread_spin_init): Edit renamed function call. * nonportable.c (pthread_num_processors_np): New. (pthread_getprocessors_np): Renamed to ptw32_getprocessors and moved to private.c. * private.c (pthread_getprocessors): Moved here from nonportable.c. * pthread.def (pthread_getprocessors_np): Removed from export list. * rwlock.c (pthread_rwlockattr_init): New. (pthread_rwlockattr_destroy): New. (pthread_rwlockattr_getpshared): New. (pthread_rwlockattr_setpshared): New.

Remove unused autoconf files; Add the file COPYING, which describes the pthread-win32 license relative to the FSF LGPL.

Contributed by - Alexander Terekhov. * condvar.c: Fixed lost signal bug reported by Timur Aydin (taydin@snet.net). [RPJ (me) didn't translate the original algorithm correctly.] * semaphore.c: Added sem_post_multiple; this is a useful routine, but it doesn't appear to be standard. For now it's not an exported function.
2001-06-11 * semaphore.h (sem_t): Fixed for compile and test.rpj
* implement.h (sem_t_): Likewise. * semaphore.c: Likewise. * private.c (ptw32_sem_timedwait): Updated to use new opaque sem_t. tests/ * mutex5.c: Insert inert change to quell compiler warnings. * condvar3_2.c: Remove unused variable.
2001-06-07 * semaphore.h (sem_t): Is now an opaque pointer;rpj
moved actual definition to implement.h. * implement.h (sem_t_): Move here from semaphore.h; was the definition of sem_t. * semaphore.c: Wherever necessary, changed use of sem from that of a pointer to a pointer-pointer; added extra checks for a valid sem_t; NULL sem_t when it is destroyed; added extra checks when creating and destroying sem_t elements in the NEED_SEM code branches; changed from using a pthread_mutex_t ((*sem)->mutex) to CRITICAL_SECTION ((*sem)->sem_lock_cs) in NEED_SEM branches for access serialisation.
2000-12-29./ChangeLog:rpj
2000-12-29 Ross Johnson <rpj@special.ise.canberra.edu.au> * Makefile: Back-out "for" loops which don't work. * GNUmakefile: Remove the fake.a target; add the "realclean" target; don't remove built libs under the "clean" target. * config.h: Add a guard against multiple inclusion. * semaphore.h: Add some defines from config.h to make semaphore.h independent of config.h when building apps. * pthread.h (_errno): Back-out previous fix until we know how to fix it properly. * implement.h (lockCount): Add missing element to pthread_mutex_t_. * sync.c (pthread_join): Spelling fix in comment. * private.c (ptw32_threadStart): Reset original termination function (C++). (ptw32_threadStart): Cleanup detached threads early in case the library is statically linked. (ptw32_callUserDestroyRoutines): Remove [SEH] __try block from destructor call so that unhandled exceptions will be passed through to the system; call terminate() from [C++] try block for the same reason. * tsd.c (pthread_getspecific): Add comment. * mutex.c (pthread_mutex_init): Initialise new elements in pthread_mutex_t. (pthread_mutex_unlock): Invert "pthread_equal()" test. 2000-12-28 Ross Johnson <rpj@special.ise.canberra.edu.au> * semaphore.c (mode_t): Use ifndef HAVE_MODE_T to include definition. * config.h.in (HAVE_MODE_T): Added. (_UWIN): Start adding defines for the UWIN package. ./tests/ChangeLog: 2000-12-29 Ross Johnson <rpj@special.ise.canberra.edu.au> * GNUmakefile: Add mutex4 test; ensure libpthreadw32.a is removed for "clean" target. * Makefile: Add mutex4 test. * exception3.c: Remove SEH code; automatically pass the test under SEH (which is an N/A environment). * mutex4.c: New test. * eyal1.c (do_work_unit): Add a dummy "if" to force the optimiser to retain code; reduce thread work loads. * condvar8.c (main): Add an additional "assert" for debugging; increase pthread_cond_signal timeout.
