* pthread_mutex_trylock.c: Should return EBUSY rather than EDEADLK. * pthread_mutex_destroy.c: Remove redundant ownership test (the trylock call does this for us); do not destroy a recursively locked mutex.

2002-03-02Changes to documentation and makefiles.rpj
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.
2002-02-27 * exception3.c (terminateFunction): For MSVC++, callrpj
exit() rather than pthread_exit(). Add comments to explain why. * rwlock2_t.c: New test. * rwlock3_t.c: New test. * rwlock4_t.c: New test. * rwlock5_t.c: New test. * rwlock6_t.c: New test. * rwlock6_t2.c: New test. * rwlock6.c (main): Swap thread and result variables to correspond to actual thread functions. * rwlock1.c: Change test description comment to correspond to the actual test.
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.

conditional compilation; refinements; bug fixes. See the ChangeLog.
2002-02-03Change #pragma inline_depth(8) to use empty () for default value.rpj
2002-02-02 * cancel.c: Rearranged some code and introduced checksrpj
to disable cancelation at the start of a thread's cancelation run to prevent double cancelation. The main problem arises if a thread is canceling and then receives a subsequent async cancel request. * private.c: Likewise. * condvar.c: Place pragmas around cleanup_push/pop to turn off inline optimisation (/Obn where n>0 - MSVC only). Various optimisation switches in MSVC turn this on, which interferes with the way that cleanup handlers are run in C++ EH and SEH code. Application code compiled with inline optimisation must also wrap cleanup_push/pop blocks with the pragmas, e.g. #pragma inline_depth(0) pthread_cleanup_push(...) ... pthread_cleanup_pop(...) #pragma inline_depth(8) * rwlock.c: Likewise. * mutex.c: Remove attempts to inline some functions. * signal.c: Modify misleading comment. tests/ * mutex8: New test. * mutex8n: New test. * mutex8e: New test. * mutex8r: New test. * cancel6a: New test. * cancel6d: New test. * cleanup0.c: Add pragmas for inline optimisation control. * cleanup1.c: Add pragmas for inline optimisation control. * cleanup2.c: Add pragmas for inline optimisation control. * cleanup3.c: Add pragmas for inline optimisation control. * condvar7.c: Add pragmas for inline optimisation control. * condvar8.c: Add pragmas for inline optimisation control. * condvar9.c: Add pragmas for inline optimisation control.

* 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.
2002-01-13 * attr.c (pthread_attr_setscope): Fix struct pointerrpj
indirection error introduced 2002-01-04. (pthread_attr_getscope): Likewise. * pthread.dsp (SOURCE): Add missing source files. ./tests/: * exception3.c (main): Shorten wait time. * mutex7.c: New test. * mutex7n.c: New test. * mutex7e.c: New test. * mutex7r.c: New test. * mutex6.c: Modified to avoid leaving the locked mutex around on exit.
2001-12-18Include an interim complete Copyright notice in each source file;rpj
Remove unused autoconf files; Add the file COPYING, which describes the pthread-win32 license relative to the FSF LGPL.
2001-10-25 * GNUmakefile (libwsock32): Add to linker flags forrpj
WSAGetLastError() and WSASetLastError(). * Makefile (wsock32.lib): Likewise. * create.c: Minor mostly inert changes. * implement.h (PTW32_MAX): Move into here and renamed from sched.h. (PTW32_MIN): Likewise. * GNUmakefile (TEST_ICE): Define if testing internal implementation of InterlockedCompareExchange. * Makefile (TEST_ICE): Likewise. * private.c (TEST_ICE): Likewise.
2001-10-25 * barrier.c: Move _LONG and _LPLONG defines intorpj
implement.h; rename to PTW32_INTERLOCKED_LONG and PTW32_INTERLOCKED_LPLONG respectively. * spin.c: Likewise; ptw32_interlocked_compare_exchange used in place of InterlockedCompareExchange directly. * global.c (ptw32_interlocked_compare_exchange): Add prototype for this new routine pointer to be used when InterlockedCompareExchange isn't supported by Windows. * nonportable.c (pthread_win32_process_attach_np): Check for support of InterlockedCompareExchange in kernel32 and assign its address to ptw32_interlocked_compare_exchange if it exists, or our own ix86 specific implementation ptw32_InterlockedCompareExchange. *private.c (ptw32_InterlockedCompareExchange): An implementation of InterlockedCompareExchange() which is specific to ix86; written directly in assembler for either MSVC or GNU C; needed because Windows 95 doesn't support InterlockedCompareExchange(). * sched.c (sched_get_priority_min): Extend to return THREAD_PRIORITY_IDLE. (sched_get_priority_max): Extend to return THREAD_PRIORITY_CRITICAL.
