In particular, - although each once_control uses it's own event to block on, a global CS is - required to manage it - since the event must be either re-usable or - re-creatable under cancelation. This is not needed in the non-cancelable - design because it is able to mark the event as closed (forever). - - When uncontested, a CS operation is equivalent to an Interlocked operation - in speed. So, in the final design with cancelability, an uncontested - once_control operation involves a minimum of five interlocked operations - (including the LeaveCS operation). - - ALTERNATIVES: - An alternative design from Alexander Terekhov proposed using a named mutex, - as sketched below:- - - if (!once_control) { // May be in TLS - named_mutex::guard guard(&once_control2); - if (!once_control2) { - - once_control2 = true; - } - once_control = true; - } - - A more detailed description of this can be found here:- - http://groups.yahoo.com/group/boost/message/15442 - - [Although the definition of a suitable PTHREAD_ONCE_INIT precludes use of the - TLS located flag, this is not critical.] - - There are three primary concerns though:- - 1) The [named] mutex is 'created' even in the uncontended case. - 2) A system wide unique name must be generated. - 3) Win32 mutexes are VERY slow even in the uncontended case.

I have deviated slightly from AT's logic to add the waiters - count, which has made the code more complicated by adding cancelation - cleanup. This also appears to have broken the VCE (C++ EH) version of - the library (the same problem as previously reported - see BUGS #2), - only apparently not fixable using the usual workaround, nor by turning - all optimisation off.

On IA-32 uni-processor systems, it's faster to use the - CMPXCHG instruction without locking the bus than to use the XCHG - instruction, which always locks the bus. This makes the two variants - equal for the non-contended lock (fast lane) execution path on up - IA-32. Testing shows that the xchg variant is faster on up IA-32 as - well if the test forces higher lock contention frequency, even though - kernel calls should be dominating the times (on up IA-32, both - variants used CMPXCHG instructions and neither locked the bus). - * pthread_mutex_timedlock.c pthread_mutex_timedlock(): Similarly. - * pthread_mutex_trylock.c (pthread_mutex_trylock): Similarly. - * pthread_mutex_unlock.c (pthread_mutex_unlock): Similarly. - * ptw32_InterlockedCompareExchange.c (ptw32_InterlockExchange): New - function. - (PTW32_INTERLOCKED_EXCHANGE): Sets up macro to use inlined - ptw32_InterlockedExchange. - * implement.h (PTW32_INTERLOCKED_EXCHANGE): Set default to - InterlockedExchange(). - * Makefile: Building using /Ob2 so that asm sections within inline - functions are inlined. - -2004-10-08 Ross Johnson - - * pthread_mutex_destroy.c (pthread_mutex_destroy): Critical Section - element is no longer required. - * pthread_mutex_init.c (pthread_mutex_init): Likewise. - * pthread_mutex_lock.c (pthread_mutex_lock): New algorithm following - Drepper's paper at http://people.redhat.com/drepper/futex.pdf, but - using the existing semaphore in place of the futex described in the - paper.

There are - other instances of similar harmless race conditions that have not - been identified as issues.] - -2004-09-09 Ross Johnson - - * pthread.h: Declare additional types as volatile. - -2004-08-27 Ross Johnson - - * pthread_barrier_wait.c (pthread_barrier_wait): Remove excessive code - by substituting the internal non-cancelable version of sem_wait - (ptw32_semwait). - -2004-08-25 Ross Johnson - - * pthread_join.c (pthread_join): Rewrite and re-order the conditional - tests in an attempt to improve efficiency and remove a race - condition. - -2004-08-23 Ross Johnson - - * create.c (pthread_create): Don't create a thread if the thread - id pointer location (first arg) is inaccessible. A memory - protection fault will result if the thread id arg isn't an accessible - location. This is consistent with GNU/Linux but different to - Solaris or MKS (and possibly others), which accept NULL as meaning - 'don't return the created thread's ID'. Applications that run - using pthreads-win32 will run on all other POSIX threads - implementations, at least w.r.t. this feature. - - It was decided not to copy the Solaris et al behaviour because, - although it would have simplified some application porting (but only - from Solaris to Windows), the feature is not technically necessary, - and the alternative segfault behaviour helps avoid buggy application - code. - -2004-07-01 Anuj Goyal - - * builddmc.bat: New; Windows bat file to build the library. - * config.h (__DMC__): Support for Digital Mars compiler. - * create.c (__DMC__): Likewise. - * pthread_exit.c (__DMC__): Likewise. - * pthread_join.c (__DMC__): Likewise. - * ptw32_threadDestroy.c (__DMC__): Likewise. - * ptw32_threadStart.c (__DMC__): Likewise. - * ptw32_throw.c (__DMC__): Likewise. - -2004-06-29 Anuj Goyal - - * pthread.h (__DMC__): Initial support for Digital Mars compiler. - -2004-06-29 Will Bryant - - * README.Borland: New; description of Borland changes. - * Bmakefile: New makefile for the Borland make utility. - * ptw32_InterlockedCompareExchange.c: - Add Borland compatible asm code. - -2004-06-26 Jason Bard - - * pthread.h (HAVE_STRUCT_TIMESPEC): If undefined, define it - to avoid timespec struct redefined errors elsewhere in an - application. - -2004-06-21 Ross Johnson - - * pthread.h (PTHREAD_RECURSIVE_MUTEX_INITIALIZER): Mutex - initialiser added for compatibility with Linux threads and - others; currently not included in SUSV3. - * pthread.h (PTHREAD_ERRORCHECK_MUTEX_INITIALIZER): Likewise. - * pthread.h (PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP): Likewise. - * pthread.h (PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP): Likewise. - - * ptw32_mutex_check_need_init.c (ptw32_mutex_check_need_init): - Add new initialisers. - - * pthread_mutex_lock.c (pthread_mutex_lock): Check for new - initialisers. - * pthread_mutex_trylock.c (pthread_mutex_trylock): Likewise. - * pthread_mutex_timedlock.c (pthread_mutex_timedlock): Likewise. - * pthread_mutex_unlock.c (pthread_mutex_unlock): Likewise. - * pthread_mutex_destroy.c (pthread_mutex_destroy): Likewise. - -2004-05-20 Ross Johnson - - * README.NONPORTABLE: Document pthread_win32_test_features_np(). - * FAQ: Update various answers. - -2004-05-19 Ross Johnson - - * Makefile: Don't define _WIN32_WINNT on compiler command line. - * GNUmakefile: Likewise. - -2004-05-16 Ross Johnson - - * pthread_cancel.c (pthread_cancel): Adapted to use auto-detected - QueueUserAPCEx features at run-time. - (ptw32_RegisterCancelation): Drop in replacement for QueueUserAPCEx() - if it can't be used.

Esssentially just add - the cdecl attribute to all exposed function prototypes so that Watcom - generates function call code compatible with non-Watcom built libraries. - By default, Watcom uses registers to pass function args if possible rather - than pushing to stack. - * semaphore.h: Likewise. - * sched.h: Likewise. - * pthread_cond_wait.c (ptw32_cond_wait_cleanup): Define with cdecl attribute - for Watcom compatibility. This routine is called via pthread_cleanup_push so - it had to match function arg definition. - * Wmakefile: New makefile for Watcom builds. - -2003-09-14 Ross Johnson - - * pthread_setschedparam.c (pthread_setschedparam): Attempt to map - all priority levels between max and min (as returned by - sched_get_priority_min/max) to reasonable Win32 priority levels - i.e. - levels between THREAD_PRIORITY_LOWEST/IDLE to THREAD_PRIORITY_LOWEST and - between THREAD_PRIORITY_HIGHEST/TIME_CRITICAL to THREAD_PRIORITY_HIGHEST - while others remain unchanged; record specified thread priority level - for return by pthread_getschedparam. - - Note that, previously, specified levels not matching Win32 priority levels - would silently leave the current thread priority unaltered. - - * pthread_getschedparam.c (pthread_getschedparam): Return the priority - level specified by the latest pthread_setschedparam or pthread_create rather - than the actual running thread priority as returned by GetThreadPriority - as - required by POSIX. I.e. temporary or adjusted actual priority levels are not - returned by this routine. - - * pthread_create.c (pthread_create): For priority levels specified via - pthread attributes, attempt to map all priority levels between max and - min (as returned by sched_get_priority_min/max) to reasonable Win32 - priority levels; record priority level given via attributes, or - inherited from parent thread, for later return by pthread_getschedparam. - - * ptw32_new.c (ptw32_new): Initialise pthread_t_ sched_priority element. - - * pthread_self.c (pthread_self): Set newly created implicit POSIX thread - sched_priority to Win32 thread's current actual priority. Temporarily - altered priorities can't be avoided in this case. - - * implement.h (struct pthread_t_): Add new sched_priority element. - -2003-09-12 Ross Johnson - - * sched_get_priority_min.c (sched_get_priority_min): On error should return -1 - with errno set. - * sched_get_priority_max.c (sched_get_priority_max): Likewise. - -2003-09-03 Ross Johnson - - * w32_cancelableWait.c (ptw32_cancelable_wait): Allow cancelation - of implicit POSIX threads as well. - -2003-09-02 Ross Johnson - - * pthread_win32_attach_detach_np.c (pthread_win32_thread_detach_np): - Add comment. - - * pthread_exit.c (pthread_exit): Fix to recycle the POSIX thread handle in - addition to calling user TSD destructors. Move the implicit POSIX thread exit - handling to ptw32_throw to centralise the logic. - - * ptw32_throw.c (ptw32_throw): Implicit POSIX threads have no point - to jump or throw to, so cleanup and exit the thread here in this case. For - processes using the C runtime, the exit code will be set to the POSIX - reason for the throw (i.e. PTHREAD_CANCEL or the value given to pthread_exit). - Note that pthread_exit() already had similar logic, which has been moved to - here. - - * ptw32_threadDestroy.c (ptw32_threadDestroy): Don't close the Win32 handle - of implicit POSIX threads - expect this to be done by Win32? - -2003-09-01 Ross Johnson - - * pthread_self.c (pthread_self): The newly aquired pthread_t must be - assigned to the reuse stack, not freed, if the routine fails somehow. - -2003-08-13 Ross Johnson - - * pthread_getschedparam.c (pthread_getschedparam): An invalid thread ID - parameter was returning an incorrect error value; now uses a more exhaustive - check for validity. - - * pthread_setschedparam.c (pthread_setschedparam): Likewise. - - * pthread_join.c (pthread_join): Now uses a more exhaustive - check for validity. - - * pthread_detach.c (pthread_detach): Likewise. - - * pthread_cancel.c (pthread_cancel): Likewise. - - * ptw32_threadDestroy.c (ptw32_threadDestroy): pthread_t structs are - never freed - push them onto a stack for reuse. - - * ptw32_new.c (ptw32_new): Check for reusable pthread_t before dynamically - allocating new memory for the struct. - - * pthread_kill.c (pthread_kill): New file; new routine; takes only a zero - signal arg so that applications can check the thread arg for validity; checks - that the underlying Win32 thread HANDLE is valid. - - * pthread.h (pthread_kill): Add prototype. - - * ptw32_reuse.c (ptw32_threadReusePop): New file; new routine; pop a - pthread_t off the reuse stack. pthread_t_ structs that have been destroyed, i.e. - have exited detached or have been joined, are cleaned up and put onto a reuse - stack. Consequently, thread IDs are no longer freed once calloced. The library - will attempt to get a struct off this stack before asking the system to alloc - new memory when creating threads. The stack is guarded by a global mutex. - (ptw32_threadReusePush): New routine; push a pthread_t onto the reuse stack. - - * implement.h (ptw32_threadReusePush): Add new prototype. - (ptw32_threadReusePop): Likewise. - (pthread_t): Add new element. - - * ptw32_processTerminate.c (ptw32_processTerminate): Delete the thread - reuse lock; free all thread ID structs on the thread reuse stack. - - * ptw32_processInitialize.c (ptw32_processInitialize): Initialise the - thread reuse lock. - -2003-07-19 Ross Johnson - - * GNUmakefile: modified to work under MsysDTK environment. - * pthread_spin_lock.c (pthread_spin_lock): Check for NULL arg. - * pthread_spin_unlock.c (pthread_spin_unlock): Likewise. - * pthread_spin_trylock.c (pthread_spin_trylock): Likewise; - fix incorrect pointer value if lock is dynamically initialised by - this function. - * sem_init.c (sem_init): Initialise sem_t value to quell compiler warning. - * sem_destroy.c (sem_destroy): Likewise. - * ptw32_threadStart.c (non-MSVC code sections): Include rather - than old-style ; fix all std:: namespace entities such as - std::terminate_handler instances and associated methods. - * ptw32_callUserDestroyRoutines.c (non-MSVC code sections): Likewise. - -2003-06-24 Piet van Bruggen - - * pthread_spin_destroy.c (pthread_spin_destroy): Was not freeing the - spinlock struct. - -2003-06-22 Nicolas Barry - - * pthread_mutex_destroy.c (pthread_mutex_destroy): When called - with a recursive mutex that was locked by the current thread, the - function was failing with a success return code. - -2003-05-15 Steven Reddie - - * pthread_win32_attach_detach_np.c (pthread_win32_process_detach_np): - NULLify ptw32_selfThreadKey after the thread is destroyed, otherwise - destructors calling pthreads routines might resurrect it again, creating - memory leaks. Call the underlying Win32 Tls routine directly rather than - pthread_setspecific(). - (pthread_win32_thread_detach_np): Likewise. - -2003-05-14 Viv - - * pthread.dsp: Change /MT compile flag to /MD. - -2003-03-04 Alexander Terekhov - - * pthread_mutex_timedlock.c (pthread_mutex_timedlock): Fix failure to - set ownership of mutex on second grab after abstime timeout. - - bug reported by Robert Strycek - -2002-12-17 Thomas Pfaff - - * pthread_mutex_lock.c (ptw32_semwait): New static routine to provide - a non-cancelable sem_wait() function. This is consistent with the - way that pthread_mutex_timedlock.c does it. - (pthread_mutex_lock): Use ptw32_semwait() instead of sem_wait(). - -2002-12-11 Thomas Pfaff - - * 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. - -2002-09-20 Michael Johnson - - * pthread_cond_destroy.c (pthread_cond_destroy): - When two different threads exist, and one is attempting to - destroy a condition variable while the other is attempting to - initialize a condition variable that was created with - PTHREAD_COND_INITIALIZER, a deadlock can occur. Shrink - the ptw32_cond_list_lock critical section to fix it. - -2002-07-31 Ross Johnson - - * ptw32_threadStart.c (ptw32_threadStart): Thread cancelLock - destruction moved to ptw32_threadDestroy(). - - * ptw32_threadDestroy.c (ptw32_threadDestroy): Destroy - the thread's cancelLock. Moved here from ptw32_threadStart.c - to cleanup implicit threads as well. - -2002-07-30 Alexander Terekhov - - * pthread_cond_wait.c (ptw32_cond_wait_cleanup): - Remove code designed to avoid/prevent spurious wakeup - problems. It is believed that the sem_timedwait() call - is consuming a CV signal that it shouldn't and this is - breaking the avoidance logic. - -2002-07-30 Ross Johnson - - * sem_timedwait.c (sem_timedwait): Tighten checks for - unreasonable abstime values - that would result in - unexpected timeout values. - - * w32_CancelableWait.c (ptw32_cancelable_wait): - Tighten up return value checking and add comments. - - -2002-06-08 Ross Johnson - - * sem_getvalue.c (sem_getvalue): Now returns a value for the - NEED_SEM version (i.e. earlier versions of WinCE). - - -2002-06-04 Rob Fanner - - * sem_getvalue.c (sem_getvalue): The Johnson M. Hart - approach didn't work - we are forced to take an - intrusive approach. We try to decrement the sema - and then immediately release it again to get the - value. There is a small probability that this may - block other threads, but only momentarily. - -2002-06-03 Ross Johnson - - * sem_init.c (sem_init): Initialise Win32 semaphores - to _POSIX_SEM_VALUE_MAX (which this implementation - defines in pthread.h) so that sem_getvalue() can use - the trick described in the comments in sem_getvalue(). - * pthread.h (_POSIX_SEM_VALUE_MAX): Defined. - (_POSIX_SEM_NSEMS_MAX): Defined - not used but may be - useful for source code portability. - -2002-06-03 Rob Fanner - - * sem_getvalue.c (sem_getvalue): Did not work on NT. - Use approach suggested by Johnson M. Hart in his book - "Win32 System Programming". - -2002-02-28 Ross Johnson - - * errno.c: Compiler directive was incorrectly including code. - * 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.

Deferred cancels will interrupt the - wait. - -2002-02-07 Ross Johnson - - Reduced name space pollution. - ----------------------------- - When the appropriate symbols are defined, the headers - will restrict the definitions of new names. In particular, - it must be possible to NOT include the - header and related definitions with some combination - of symbol definitions.

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. - -2002-02-01 Ross Johnson - - * semaphore.c (sem_trywait): Fix missing errno return - for systems that define NEED_SEM (e.g. early WinCE). - * mutex.c (pthread_mutex_timedlock): Return ENOTSUP - for systems that define NEED_SEM since they don't - have sem_trywait(). - -2002-01-27 Ross Johnson - - * mutex.c (pthread_mutex_timedlock): New function suggested by - Alexander Terekhov.

Set to NULL in PTHREAD_MUTEX_INITIALIZER. - The pthread_mutex_*() routines will try to optimise performance - by choosing either mutexes or critical sections as the basis - for pthread mutexes for each indevidual mutex. - (pthread_mutexattr_t_): Add 'forcecs' element. - Some applications may choose to force use of critical sections - if they know that:- - the mutex is PROCESS_PRIVATE and, - either the OS supports TryEnterCriticalSection() or - pthread_mutex_trylock() will never be called on the mutex. - This attribute will be setable via a non-portable routine. - - Note: We don't yet support PROCESS_SHARED mutexes, so the - implementation as it stands will default to Win32 mutexes only if - the OS doesn't support TryEnterCriticalSection.

Provides serialised - access to the internal state of the uninitialised static mutex. - Called from pthread_mutex_trylock() and pthread_mutex_lock() which - do a quick unguarded test to check if _mutex_check_need_init() - needs to be called. This is safe as the test is conservative - and is repeated inside the guarded section of - _mutex_check_need_init(). Thus in all calls except the first - calls to lock static mutexes, the additional overhead to lock any - mutex is a single memory fetch and test for zero. - - * pthread.h (pthread_mutex_t_): Add 'staticinit' member. Mutexes - initialised by PTHREAD_MUTEX_INITIALIZER aren't really initialised - until the first attempt to lock it. Using the 'valid' - flag (which flags the mutex as destroyed or not) to record this - information would be messy. It is possible for a statically - initialised mutex such as this to be destroyed before ever being - used. - - * mutex.c (pthread_mutex_trylock): Call _mutex_check_need_init() - to test/init PTHREAD_MUTEX_INITIALIZER mutexes. - (pthread_mutex_lock): Ditto. - (pthread_mutex_unlock): Add check to ensure we don't try to unlock - an unitialised static mutex. - (pthread_mutex_destroy): Add check to ensure we don't try to delete - a critical section that we never created. Allows us to destroy - a static mutex that has never been locked (and hence initialised). - (pthread_mutex_init): Set 'staticinit' flag to 0 for the new mutex. - -Sun Jan 17 12:01:26 1999 Ross Johnson - - * private.c (ptw32_sem_timedwait): Move from semaphore.c. - - * semaphore.c : Remove redundant #includes. - (ptw32_sem_timedwait): Move to private.c. - (sem_wait): Add missing abstime arg to pthreadCancelableWait() call. - -Fri Jan 15 23:38:05 1999 Ross Johnson - - * condvar.c (cond_timedwait): Remove comment. - -Fri Jan 15 15:41:28 1999 Ross Johnson - - * pthread.h: Add new 'abstime' arg to pthreadCancelableWait() - prototype. - - * condvar.c (cond_timedwait): New generalised function called by - both pthread_cond_wait() and pthread_cond_timedwait(). This is - essentially pthread_cond_wait() renamed and modified to add the - 'abstime' arg and call the new ptw32_sem_timedwait() instead of - sem_wait(). - (pthread_cond_wait): Now just calls the internal static - function cond_timedwait() with an INFINITE wait. - (pthread_cond_timedwait): Now implemented. Calls the internal - static function cond_timedwait(). - - * implement.h (ptw32_sem_timedwait): New internal function - prototype. - - * misc.c (pthreadCancelableWait): Added new 'abstime' argument - to allow shorter than INFINITE wait. - - * semaphore.c (ptw32_sem_timedwait): New function for internal - use. This is essentially sem_wait() modified to add the - 'abstime' arg and call the modified (see above) - pthreadCancelableWait(). - -Thu Jan 14 14:27:13 1999 Ross Johnson - - * cleanup.c: Correct _cplusplus to __cplusplus wherever used. - - * Makefile.in: Add CC=g++ and add -fhandle-exceptions to CFLAGS. - The derived Makefile will compile all units of the package as C++ - so that those which include try/catch exception handling should work - properly. The package should compile ok if CC=gcc, however, exception - handling will not be included and thus thread cancellation, for - example, will not work. - - * cleanup.c (ptw32_pop_cleanup): Add #warning to compile this - file as C++ if using a cygwin32 environment. Perhaps the whole package - should be compiled using g++ under cygwin. - - * private.c (ptw32_threadStart): Change #error directive - into #warning and bracket for __CYGWIN__ and derivative compilers. - -Wed Jan 13 09:34:52 1999 Ross Johnson - - * build.bat: Delete old binaries before compiling/linking. - -Tue Jan 12 09:58:38 1999 Tor Lillqvist - - * dll.c: The Microsoft compiler pragmas probably are more - appropriately protected by _MSC_VER than by _WIN32. - - * pthread.h: Define ETIMEDOUT.

See URL for details:- + http://sources.redhat.com/ml/pthreads-win32/2005/msg00029.html + This uses late initialisation similar to the technique already used for + pthreads-win32 mutexes and semaphores (from Alexander Terekhov). + + The subsequent cancelation cleanup additions (by rpj) could not be implemented + without sacrificing some of the efficiency in Gottlob's design. In particular, + although each once_control uses it's own event to block on, a global CS is + required to manage it - since the event must be either re-usable or + re-creatable under cancelation. This is not needed in the non-cancelable + design because it is able to mark the event as closed (forever). + + When uncontested, a CS operation is equivalent to an Interlocked operation + in speed.

Nothing definable here will make the library +# non-compliant, but applications that make assumptions that POSIX +# does not garrantee may fail or misbehave under some settings. +# +# PTW32_THREAD_ID_REUSE_INCREMENT +# Purpose: +# POSIX says that applications should assume that thread IDs can be +# recycled. However, Solaris and some other systems use a [very large] +# sequence number as the thread ID, which provides virtual uniqueness. +# Pthreads-win32 provides pseudo-unique IDs when the default increment +# (1) is used, but pthread_t is not a scalar type like Solaris's. +# +# Usage: +# Set to any value in the range: 0 <= value <= 2^wordsize +# +# Examples: +# Set to 0 to emulate non recycle-unique behaviour like Linux or *BSD. +# Set to 1 for recycle-unique thread IDs (this is the default). +# Set to some other +ve value to emulate smaller word size types +# (i.e. will wrap sooner). +# +#PTW32_FLAGS = "-DPTW32_THREAD_ID_REUSE_INCREMENT=0" +# +# ---------------------------------------------------------------------- + +GC_CFLAGS = $(PTW32_FLAGS) +GCE_CFLAGS =

fixes in this release since 2.8.0 have NOT been applied to the -1.x.x series. - -Version 1 no longer maintained ------------------------------- -The 1.x.x series is no longer maintained. However, if you really need a -version 1, the differences between 1.11.0 and 2.7.0 are very small, mainly -revolving around the pthread_once_t_ struct. Those differences applied -as a patch to the current 2.x.x should work. Don't forget to change -the version numbering in pthread.h before building. If you distribute -such a version 1.x.x please bear in mind that your numbers may clash -with those of others doing the same thing. Please consider also making -identifying changes in version.rc to differentiate your build. - -Testing and verification ------------------------- -The current CVS head version has been tested on an SMP architecture -(AMD Phenom 9750 Quad Core) by running the MinGW32 (GCC) builds against -the full test suite, stress tests and benchmarks. - -New Features ------------- -Dependence on the winsock library is now discretionary via -#define RETAIN_WSALASTERROR in config.h. It is undefined by default unless -WINCE is defined (because I (RJ) am unsure of the dependency there). -- Ramiro Polla - -(MSC and GNU builds) The statically linked library now automatically -initialises and cleans up on program start/exit, i.e. statically linked -applications need not call the routines pthread_win32_process_attach_np() -and pthread_win32_process_detach_np() explicitly. The per-thread routine -pthread_win32_thread_detach_np() is also called at program exit to cleanup -POSIX resources acquired by the primary Windows native thread (if I (RJ) -understand the process correctly). Other Windows native threads that call -POSIX API routines may need to call the thread detach routine on thread -exit if the application depends on reclaimed POSIX resources or running -POSIX TSD (TLS) destructors. -See README.NONPORTABLE for descriptions of these routines. -- Ramiro Polla - -Bug fixes ---------- -Various modifications and fixes to build and test for WinCE. -- Marcel Ruff, Sinan Kaya - -Fix pthread_cond_destroy() - should not be a cancellation point. Other -minor build problems fixed. -- Romano Paolo Tenca - -Remove potential deadlock condition from pthread_cond_destroy(). -- Eric Berge - -Various modifications to build and test for Win64. -- Kip Streithorst - -Various fixes to the QueueUserAPCEx async cancellation helper DLL -(this is a separate download) and pthreads code cleanups. -- Sebastian Gottschalk - -Removed potential NULL pointer reference. -- Robert Kindred - -Removed the requirement that applications restrict the number of threads -calling pthread_barrier_wait() [on the same barrier] to just the barrier -count in order to avoid contention and dead lock. Also reduced the -contention between barrier_wait and barrier_destroy. This change will -have slowed barriers down slightly but halves the number of semaphores -consumed per barrier to one. -- Ross Johnson - -RELEASE 2.8.0 -------------- -(2006-12-22) - -General -------- -New bug fixes in this release since 2.7.0 have not been applied to the -version 1.x.x series. It is probably time to drop version 1. - -Testing and verification ------------------------- -This release has not yet been tested on SMP architechtures. All tests pass -on a uni-processor system. - -Bug fixes ---------- -Sem_destroy could return EBUSY even though no threads were waiting on the -semaphore. Other races around invalidating semaphore structs (internally) -have been removed as well. - -New tests ---------- -semaphore5.c - tests the bug fix referred to above. - - -RELEASE 2.7.0 -------------- -(2005-06-04) - -General -------- -All new features in this release have been back-ported in release 1.11.0, -including the incorporation of MCS locks in pthread_once, however, versions -1 and 2 remain incompatible even though they are now identical in -performance and functionality. - -Testing and verification ------------------------- -This release has been tested (passed the test suite) on both uni-processor -and multi-processor systems. -- Tim Theisen - -Bug fixes ---------- -Pthread_once has been re-implemented to remove priority boosting and other -complexity to improve robustness. Races for Win32 handles that are not -recycle-unique have been removed. The general form of pthread_once is now -the same as that suggested earlier by Alexander Terekhov, but instead of the -'named mutex', a queue-based lock has been implemented which has the required -properties of dynamic self initialisation and destruction. This lock is also -efficient. The ABI is unaffected in as much as the size of pthread_once_t has -not changed and PTHREAD_ONCE_INIT has not changed, however, applications that -peek inside pthread_once_t, which is supposed to be opaque, will break. -- Vladimir Kliatchko - -New features ------------- -* Support for Mingw cross development tools added to GNUmakefile. -Mingw cross tools allow building the libraries on Linux. -- Mikael Magnusson - - -RELEASE 2.6.0 -------------- -(2005-05-19) - -General -------- -All of the bug fixes and new features in this release have been -back-ported in release 1.10.0. - -Testing and verification ------------------------- -This release has been tested (passed the test suite) on both uni-processor -and multi-processor systems. Thanks to Tim Theisen at TomoTherapy for -exhaustively running the MP tests and for providing crutial observations -and data when faults are detected. - -Bugs fixed ----------- - -* pthread_detach() now reclaims remaining thread resources if called after -the target thread has terminated. Previously, this routine did nothing in -this case. - -New tests ---------- - -* detach1.c - tests that pthread_detach properly invalidates the target -thread, which indicates that the thread resources have been reclaimed. - - -RELEASE 2.5.0 -------------- -(2005-05-09) - -General -------- - -The package now includes a reference documentation set consisting of -HTML formatted Unix-style manual pages that have been edited for -consistency with Pthreads-w32. The set can also be read online at: -http://sources.redhat.com/pthreads-win32/manual/index.html - -Thanks again to Tim Theisen for running the test suite pre-release -on an MP system. - -All of the bug fixes and new features in this release have been -back-ported in release 1.9.0. - -Bugs fixed ----------- - -* Thread Specific Data (TSD) key management has been ammended to -eliminate a source of (what was effectively) resource leakage (a HANDLE -plus memory for each key destruct routine/thread association). This was -not a true leak because these resources were eventually reclaimed when -pthread_key_delete was run AND each thread referencing the key had exited. -The problem was that these two conditions are often not met until very -late, and often not until the process is about to exit. - -The ammended implementation avoids the need for the problematic HANDLE -and reclaims the memory as soon as either the key is deleted OR the -thread exits, whichever is first. - -Thanks to Richard Hughes at Aculab for identifying and locating the leak. - -* TSD key destructors are now processed up to PTHREAD_DESTRUCTOR_ITERATIONS -times instead of just once. PTHREAD_DESTRUCTOR_ITERATIONS has been -defined in pthread.h for some time but not used. - -* Fix a semaphore accounting race between sem_post/sem_post_multiple -and sem_wait cancellation. This is the same issue as with -sem_timedwait that was fixed in the last release. - -* sem_init, sem_post, and sem_post_multiple now check that the -semaphore count never exceeds _POSIX_SEM_VALUE_MAX. - -* Although sigwait() is nothing more than a no-op, it should at least -be a cancellation point to be consistent with the standard. - -New tests ---------- - -* stress1.c - attempts to expose problems in condition variable -and semaphore timed wait logic. This test was inspired by Stephan -Mueller's sample test code used to identify the sem_timedwait bug -from the last release. It's not a part of the regular test suite -because it can take awhile to run. To run it: -nmake clean VC-stress - -* tsd2.c - tests that key destructors are re-run if the tsd key value is -not NULL after the destructor routine has run. Also tests that -pthread_setspecific() and pthread_getspecific() are callable from -destructors. - - -RELEASE 2.4.0 -------------- -(2005-04-26) - -General -------- - -There is now no plan to release a version 3.0.0 to fix problems in -pthread_once(). Other possible implementations of pthread_once -will still be investigated for a possible future release in an attempt -to reduce the current implementation's complexity. - -All of the bug fixes and new features in this release have been -back-ported for release 1.8.0. - -Bugs fixed ----------- - -* Fixed pthread_once race (failures on an MP system). Thanks to -Tim Theisen for running exhaustive pre-release testing on his MP system -using a range of compilers: - VC++ 6 - VC++ 7.1 - Intel C++ version 8.0 -All tests passed. -Some minor speed improvements were also done. - -* Fix integer overrun error in pthread_mutex_timedlock() - missed when -sem_timedwait() was fixed in release 2.2.0. This routine no longer returns -ENOTSUP when NEED_SEM is defined - it is supported (NEED_SEM is only -required for WinCE versions prior to 3.0). - -* Fix timeout bug in sem_timedwait(). -- Thanks to Stephan Mueller for reporting, providing diagnostic output -and test code. - -* Fix several problems in the NEED_SEM conditionally included code. -NEED_SEM included code is provided for systems that don't implement W32 -semaphores, such as WinCE prior to version 3.0. An alternate implementation -of POSIX semaphores is built using W32 events for these systems when -NEED_SEM is defined. This code has been completely rewritten in this -release to reuse most of the default POSIX semaphore code, and particularly, -to implement all of the sem_* routines supported by pthreads-win32. Tim -Theisen also run the test suite over the NEED_SEM code on his MP system. All -tests passed. - -* The library now builds without errors for the Borland Builder 5.5 compiler. - -New features ------------- - -* pthread_mutex_timedlock() and all sem_* routines provided by -pthreads-win32 are now implemented for WinCE versions prior to 3.0. Those -versions did not implement W32 semaphores. Define NEED_SEM in config.h when -building the library for these systems. - -Known issues in this release ----------------------------- - -* pthread_once is too complicated - but it works as far as testing can -determine.. - -* The Borland version of the dll fails some of the tests with a memory read -exception. The cause is not yet known but a compiler bug has not been ruled -out. - - -RELEASE 2.3.0 -------------- -(2005-04-12) - -General -------- - -Release 1.7.0 is a backport of features and bug fixes new in -this release. See earlier notes under Release 2.0.0/General. - -Bugs fixed ----------- - -* Fixed pthread_once potential for post once_routine cancellation -hanging due to starvation. See comments in pthread_once.c. -Momentary priority boosting is used to ensure that, after a -once_routine is cancelled, the thread that will run the -once_routine is not starved by higher priority waiting threads at -critical times. Priority boosting occurs only AFTER a once_routine -cancellation, and is applied only to that once_control. The -once_routine is run at the thread's normal base priority. - -New tests ---------- - -* once4.c: Aggressively tests pthread_once() under realtime -conditions using threads with varying priorities. Windows' -random priority boosting does not occur for threads with realtime -priority levels. - - -RELEASE 2.2.0 -------------- -(2005-04-04) - -General -------- - -* Added makefile targets to build static link versions of the library. -Both MinGW and MSVC. Please note that this does not imply any change -to the LGPL licensing, which still imposes psecific conditions on -distributing software that has been statically linked with this library. - -* There is a known bug in pthread_once(). Cancellation of the init_routine -exposes a potential starvation (i.e. deadlock) problem if a waiting thread -has a higher priority than the initting thread. This problem will be fixed -in version 3.0.0 of the library. - -Bugs fixed ----------- - -* Fix integer overrun error in sem_timedwait(). -Kevin Lussier - -* Fix preprocessor directives for static linking. -Dimitar Panayotov - - -RELEASE 2.1.0 -------------- -(2005-03-16) - -Bugs fixed ----------- - -* Reverse change to pthread_setcancelstate() in 2.0.0. - - -RELEASE 2.0.0 -------------- -(2005-03-16) - -General -------- - -This release represents an ABI change and the DLL version naming has -incremented from 1 to 2, e.g. pthreadVC2.dll. - -Version 1.4.0 back-ports the new functionality included in this -release. Please distribute DLLs built from that version with updates -to applications built on pthreads-win32 version 1.x.x. - -The package naming has changed, replacing the snapshot date with -the version number + descriptive information. E.g. this -release is "pthreads-w32-2-0-0-release". - -Bugs fixed ----------- - -* pthread_setcancelstate() no longer checks for a pending -async cancel event if the library is using alertable async -cancel. See the README file (Prerequisites section) for info -on adding alertable async cancelation. - -New features ------------- - -* pthread_once() now supports init_routine cancellability. - -New tests ---------- - -* Agressively test pthread_once() init_routine cancellability. - - -SNAPSHOT 2005-03-08 -------------------- -Version 1.3.0 - -Bug reports (fixed) -------------------- - -* Implicitly created threads leave Win32 handles behind after exiting. -- Dmitrii Semii - -* pthread_once() starvation problem. -- Gottlob Frege - -New tests ---------- - -* More intense testing of pthread_once(). - - -SNAPSHOT 2005-01-25 -------------------- -Version 1.2.0 - -Bug fixes ---------- - -* Attempted acquisition of a recursive mutex could cause waiting threads -to not be woken when the mutex was released. -- Ralf Kubis - -* Various package omissions have been fixed. - - -SNAPSHOT 2005-01-03 -------------------- -Version 1.1.0 - -Bug fixes ---------- - -* Unlocking recursive or errorcheck mutexes would sometimes -unexpectedly return an EPERM error (bug introduced in -snapshot-2004-11-03). -- Konstantin Voronkov - - -SNAPSHOT 2004-11-22 -------------------- -Version 1.0.0 - -This snapshot primarily fixes the condvar bug introduced in -snapshot-2004-11-03. DLL versioning has also been included to allow -applications to runtime check the Microsoft compatible DLL version -information, and to extend the DLL naming system for ABI and major -(non-backward compatible) API changes. See the README file for details. - -Bug fixes ---------- - -* Condition variables no longer deadlock (bug introduced in -snapshot-2004-11-03). -- Alexander Kotliarov and Nicolas at saintmac - -* DLL naming extended to avoid 'DLL hell' in the future, and to -accommodate the ABI change introduced in snapshot-2004-11-03. Snapshot -2004-11-03 will be removed from FTP sites. - -New features ------------- - -* A Microsoft-style version resource has been added to the DLL for -applications that wish to check DLL compatibility at runtime. - -* Pthreads-win32 DLL naming has been extended to allow incompatible DLL -versions to co-exist in the same filesystem. See the README file for details, -but briefly: while the version information inside the DLL will change with -each release from now on, the DLL version names will only change if the new -DLL is not backward compatible with older applications. - -The versioning scheme has been borrowed from GNU Libtool, and the DLL -naming scheme is from Cygwin. Provided the Libtool-style numbering rules are -honoured, the Cygwin DLL naming scheme automatcally ensures that DLL name -changes are minimal and that applications will not load an incompatible -pthreads-win32 DLL. - -Those who use the pre-built DLLs will find that the DLL/LIB names have a new -suffix (1) in this snapshot. E.g. pthreadVC1.dll etc. - -* The POSIX thread ID reuse uniqueness feature introduced in the last snapshot -has been kept as default, but the behaviour can now be controlled when the DLL -is built to effectively switch it off. This makes the library much more -sensitive to applications that assume that POSIX thread IDs are unique, i.e. -are not strictly compliant with POSIX. See the PTW32_THREAD_ID_REUSE_INCREMENT -macro comments in config.h for details. - -Other changes -------------- -Certain POSIX macros have changed. - -These changes are intended to conform to the Single Unix Specification version 3, -which states that, if set to 0 (zero) or not defined, then applications may use -sysconf() to determine their values at runtime. Pthreads-win32 does not -implement sysconf(). - -The following macros are no longer undefined, but defined and set to -1 -(not implemented): - - _POSIX_THREAD_ATTR_STACKADDR - _POSIX_THREAD_PRIO_INHERIT - _POSIX_THREAD_PRIO_PROTECT - _POSIX_THREAD_PROCESS_SHARED - -The following macros are defined and set to 200112L (implemented): - - _POSIX_THREADS - _POSIX_THREAD_SAFE_FUNCTIONS - _POSIX_THREAD_ATTR_STACKSIZE - _POSIX_THREAD_PRIORITY_SCHEDULING - _POSIX_SEMAPHORES - _POSIX_READER_WRITER_LOCKS - _POSIX_SPIN_LOCKS - _POSIX_BARRIERS - -The following macros are defined and set to appropriate values: - - _POSIX_THREAD_THREADS_MAX - _POSIX_SEM_VALUE_MAX - _POSIX_SEM_NSEMS_MAX - PTHREAD_DESTRUCTOR_ITERATIONS - PTHREAD_KEYS_MAX - PTHREAD_STACK_MIN - PTHREAD_THREADS_MAX - - -SNAPSHOT 2004-11-03 -------------------- - -DLLs produced from this snapshot cannot be used with older applications without -recompiling the application, due to a change to pthread_t to provide unique POSIX -thread IDs. - -Although this snapshot passes the extended test suite, many of the changes are -fairly major, and some applications may show different behaviour than previously, -so adopt with care. Hopefully, any changed behaviour will be due to the library -being better at it's job, not worse. - -Bug fixes ---------- - -* pthread_create() no longer accepts NULL as the thread reference arg. -A segfault (memory access fault) will result, and no thread will be -created. - -* pthread_barrier_wait() no longer acts as a cancelation point. - -* Fix potential race condition in pthread_once() -- Tristan Savatier - -* Changes to pthread_cond_destroy() exposed some coding weaknesses in several -test suite mini-apps because pthread_cond_destroy() now returns EBUSY if the CV -is still in use. - -New features ------------- - -* Added for compatibility: -PTHREAD_RECURSIVE_MUTEX_INITIALIZER, -PTHREAD_ERRORCHECK_MUTEX_INITIALIZER, -PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP, -PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP - -* Initial support for Digital Mars compiler -- Anuj Goyal - -* Faster Mutexes. These have been been rewritten following a model provided by -Alexander Terekhov that reduces kernel space checks, and eliminates some additional -critical sections used to manage a race between timedlock expiration and unlock. -Please be aware that the new mutexes do not enforce strict absolute FIFO scheduling -of mutexes, however any out-of-order lock acquisition should be very rare. - -* Faster semaphores. Following a similar model to mutexes above, these have been -rewritten to use preliminary users space checks. - -* sem_getvalue() now returns the number of waiters. - -* The POSIX thread ID now has much stronger uniqueness characteristics. The library -garrantees not to reuse the same thread ID for at least 2^(wordsize) thread -destruction/creation cycles. - -New tests ---------- - -* semaphore4.c: Tests cancelation of the new sem_wait(). - -* semaphore4t.c: Likewise for sem_timedwait(). - -* rwlock8.c: Tests and times the slow execution paths of r/w locks, and the CVs, -mutexes, and semaphores that they're built on. - - -SNAPSHOT 2004-05-16 -------------------- - -Attempt to add Watcom to the list of compilers that can build the library. -This failed in the end due to it's non-thread-aware errno. The library -builds but the test suite fails. See README.Watcom for more details. - -Bug fixes ---------- -* Bug and memory leak in sem_init() -- Alex Blanco - -* ptw32_getprocessors() now returns CPU count of 1 for WinCE. -- James Ewing - -* pthread_cond_wait() could be canceled at a point where it should not -be cancelable. Fixed. -- Alexander Terekhov - -* sem_timedwait() had an incorrect timeout calculation. -- Philippe Di Cristo - -* Fix a memory leak left behind after threads are destroyed. -- P. van Bruggen - -New features ------------- -* Ported to AMD64. -- Makoto Kato - -* True pre-emptive asynchronous cancelation of threads. This is optional -and requires that Panagiotis E. Hadjidoukas's QueueUserAPCEx package be -installed. This package is included in the pthreads-win32 self-unpacking -Zip archive starting from this snapshot. See the README.txt file inside -the package for installation details. - -Note: If you don't use async cancelation in your application, or don't need -to cancel threads that are blocked on system resources such as network I/O, -then the default non-preemptive async cancelation is probably good enough. -However, pthreads-win32 auto-detects the availability of these components -at run-time, so you don't need to rebuild the library from source if you -change your mind later. - -All of the advice available in books and elsewhere on the undesirability -of using async cancelation in any application still stands, but this -feature is a welcome addition with respect to the library's conformance to -the POSIX standard. - -SNAPSHOT 2003-09-18 -------------------- - -Cleanup of thread priority management. In particular, setting of thread -priority now attempts to map invalid Win32 values within the range returned -by sched_get_priority_min/max() to useful values. See README.NONPORTABLE -under "Thread priority". - -Bug fixes ---------- -* pthread_getschedparam() now returns the priority given by the most recent -call to pthread_setschedparam() or established by pthread_create(), as -required by the standard. Previously, pthread_getschedparam() incorrectly -returned the running thread priority at the time of the call, which may have -been adjusted or temporarily promoted/demoted. - -* sched_get_priority_min() and sched_get_priority_max() now return -1 on error -and set errno. Previously, they incorrectly returned the error value directly. - - -SNAPSHOT 2003-09-04 -------------------- - -Bug fixes ---------- -* ptw32_cancelableWait() now allows cancelation of waiting implicit POSIX -threads. - -New test --------- -* cancel8.c tests cancelation of Win32 threads waiting at a POSIX cancelation -point. - - -SNAPSHOT 2003-09-03 -------------------- - -Bug fixes ---------- -* pthread_self() would free the newly created implicit POSIX thread handle if -DuplicateHandle failed instead of recycle it (very unlikely). - -* pthread_exit() was neither freeing nor recycling the POSIX thread struct -for implicit POSIX threads. - -New feature - Cancelation of/by Win32 (non-POSIX) threads ---------------------------------------------------------- -Since John Bossom's original implementation, the library has allowed non-POSIX -initialised threads (Win32 threads) to call pthreads-win32 routines and -therefore interact with POSIX threads. This is done by creating an on-the-fly -POSIX thread ID for the Win32 thread that, once created, allows fully -reciprical interaction. This did not extend to thread cancelation (async or -deferred). Now it does. - -Any thread can be canceled by any other thread (Win32 or POSIX) if the former -thread's POSIX pthread_t value is known. It's TSD destructors and POSIX -cleanup handlers will be run before the thread exits with an exit code of -PTHREAD_CANCELED (retrieved with GetExitCodeThread()). - -This allows a Win32 thread to, for example, call POSIX CV routines in the same way -that POSIX threads would/should, with pthread_cond_wait() cancelability and -cleanup handlers (pthread_cond_wait() is a POSIX cancelation point). - -By adding cancelation, Win32 threads should now be able to call all POSIX -threads routines that make sense including semaphores, mutexes, condition -variables, read/write locks, barriers, spinlocks, tsd, cleanup push/pop, -cancelation, pthread_exit, scheduling, etc. - -Note that these on-the-fly 'implicit' POSIX thread IDs are initialised as detached -(not joinable) with deferred cancelation type. The POSIX thread ID will be created -automatically by any POSIX routines that need a POSIX handle (unless the routine -needs a pthread_t as a parameter of course). A Win32 thread can discover it's own -POSIX thread ID by calling pthread_self(), which will create the handle if -necessary and return the pthread_t value. - -New tests ---------- -Test the above new feature. - - -SNAPSHOT 2003-08-19 -------------------- - -This snapshot fixes some accidental corruption to new test case sources. -There are no changes to the library source code. - - -SNAPSHOT 2003-08-15 -------------------- - -Bug fixes ---------- - -* pthread.dsp now uses correct compile flags (/MD). -- Viv - -* pthread_win32_process_detach_np() fixed memory leak. -- Steven Reddie - -* pthread_mutex_destroy() fixed incorrect return code. -- Nicolas Barry - -* pthread_spin_destroy() fixed memory leak. -- Piet van Bruggen - -* Various changes to tighten arg checking, and to work with later versions of -MinGW32 and MsysDTK. - -* pthread_getschedparam() etc, fixed dangerous thread validity checking. -- Nicolas Barry - -* POSIX thread handles are now reused and their memory is not freed on thread exit. -This allows for stronger thread validity checking. - -New standard routine --------------------- - -* pthread_kill() added to provide thread validity checking to applications. -It does not accept any non zero values for the signal arg. - -New test cases --------------- - -* New test cases to confirm validity checking, pthread_kill(), and thread reuse. - - -SNAPSHOT 2003-05-10 -------------------- - -Bug fixes ---------- - -* pthread_mutex_trylock() now returns correct error values. -pthread_mutex_destroy() will no longer destroy a recursively locked mutex. -pthread_mutex_lock() is no longer inadvertantly behaving as a cancelation point. -- Thomas Pfaff - -* pthread_mutex_timedlock() no longer occasionally sets incorrect mutex -ownership, causing deadlocks in some applications. -- Robert Strycek and Alexander Terekhov - - -SNAPSHOT 2002-11-04 -------------------- - -Bug fixes ---------- - -* sem_getvalue() now returns the correct value under Win NT and WinCE. -- Rob Fanner - -* sem_timedwait() now uses tighter checks for unreasonable -abstime values - that would result in unexpected timeout values. - -* ptw32_cond_wait_cleanup() no longer mysteriously consumes -CV signals but may produce more spurious wakeups. It is believed -that the sem_timedwait() call is consuming a CV signal that it -shouldn't. -- Alexander Terekhov - -* Fixed a memory leak in ptw32_threadDestroy() for implicit threads. - -* Fixed potential for deadlock in pthread_cond_destroy(). -A deadlock could occur for statically declared CVs (PTHREAD_COND_INITIALIZER), -when one thread is attempting to destroy the condition variable while another -is attempting to dynamically initialize it. -- Michael Johnson - - -SNAPSHOT 2002-03-02 -------------------- - -Cleanup code default style. (IMPORTANT) ----------------------------------------------------------------------- -Previously, if not defined, the cleanup style was determined automatically -from the compiler/language, and one of the following was defined accordingly: - - __CLEANUP_SEH MSVC only - __CLEANUP_CXX C++, including MSVC++, GNU G++ - __CLEANUP_C C, including GNU GCC, not MSVC - -These defines determine the style of cleanup (see pthread.h) and, -most importantly, the way that cancelation and thread exit (via -pthread_exit) is performed (see the routine ptw32_throw() in private.c). - -In short, the exceptions versions of the library throw an exception -when a thread is canceled or exits (via pthread_exit()), which is -caught by a handler in the thread startup routine, so that the -the correct stack unwinding occurs regardless of where the thread -is when it's canceled or exits via pthread_exit(). - -In this and future snapshots, unless the build explicitly defines (e.g. -via a compiler option) __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then -the build NOW always defaults to __CLEANUP_C style cleanup. This style -uses setjmp/longjmp in the cancelation and pthread_exit implementations, -and therefore won't do stack unwinding even when linked to applications -that have it (e.g. C++ apps). This is for consistency with most -current commercial Unix POSIX threads implementations. Compaq's TRU64 -may be an exception (no pun intended) and possible future trend. - -Although it was not clearly documented before, it is still necessary to -build your application using the same __CLEANUP_* define as was -used for the version of the library that you link with, so that the -correct parts of pthread.h are included. That is, the possible -defines require the following library versions: - - __CLEANUP_SEH pthreadVSE.dll - __CLEANUP_CXX pthreadVCE.dll or pthreadGCE.dll - __CLEANUP_C pthreadVC.dll or pthreadGC.dll - -E.g. regardless of whether your app is C or C++, if you link with -pthreadVC.lib or libpthreadGC.a, then you must define __CLEANUP_C. - - -THE POINT OF ALL THIS IS: if you have not been defining one of these -explicitly, then the defaults as described at the top of this -section were being used. - -THIS NOW CHANGES, as has been explained above, but to try to make this -clearer here's an example: - -If you were building your application with MSVC++ i.e. using C++ -exceptions and not explicitly defining one of __CLEANUP_*, then -__CLEANUP_C++ was automatically defined for you in pthread.h. -You should have been linking with pthreadVCE.dll, which does -stack unwinding. - -If you now build your application as you had before, pthread.h will now -automatically set __CLEANUP_C as the default style, and you will need to -link with pthreadVC.dll. Stack unwinding will now NOT occur when a thread -is canceled, or the thread calls pthread_exit(). - -Your application will now most likely behave differently to previous -versions, and in non-obvious ways. Most likely is that locally -instantiated objects may not be destroyed or cleaned up after a thread -is canceled. - -If you want the same behaviour as before, then you must now define -__CLEANUP_C++ explicitly using a compiler option and link with -pthreadVCE.dll as you did before. - - -WHY ARE WE MAKING THE DEFAULT STYLE LESS EXCEPTION-FRIENDLY? -Because no commercial Unix POSIX threads implementation allows you to -choose to have stack unwinding. Therefore, providing it in pthread-win32 -as a default is dangerous. We still provide the choice but unless -you consciously choose to do otherwise, your pthreads applications will -now run or crash in similar ways irrespective of the threads platform -you use. Or at least this is the hope. - - -WHY NOT REMOVE THE EXCEPTIONS VERSIONS OF THE LIBRARY ALTOGETHER? -There are a few reasons: -- because there are well respected POSIX threads people who believe - that POSIX threads implementations should be exceptions aware and - do the expected thing in that context. (There are equally respected - people who believe it should not be easily accessible, if it's there - at all, for unconditional conformity to other implementations.) -- because pthreads-win32 is one of the few implementations that has - the choice, perhaps the only freely available one, and so offers - a laboratory to people who may want to explore the effects; -- although the code will always be around somewhere for anyone who - wants it, once it's removed from the current version it will not be - nearly as visible to people who may have a use for it. - - -Source module splitting ------------------------ -In order to enable smaller image sizes to be generated -for applications that link statically with the library, -most routines have been separated out into individual -source code files. - -This is being done in such a way as to be backward compatible. -The old source files are reused to congregate the individual -routine files into larger translation units (via a bunch of -# includes) so that the compiler can still optimise wherever -possible, e.g. through inlining, which can only be done -within the same translation unit. - -It is also possible to build the entire library by compiling -the single file named "pthread.c", which just #includes all -the secondary congregation source files. The compiler -may be able to use this to do more inlining of routines. - -Although the GNU compiler is able to produce libraries with -the necessary separation (the -ffunction-segments switch), -AFAIK, the MSVC and other compilers don't have this feature. - -Finally, since I use makefiles and command-line compilation, -I don't know what havoc this reorganisation may wreak amongst -IDE project file users. You should be able to continue -using your existing project files without modification. - - -New non-portable functions --------------------------- -pthread_num_processors_np(): - Returns the number of processors in the system that are - available to the process, as determined from the processor - affinity mask. - -pthread_timechange_handler_np(): - To improve tolerance against operator or time service initiated - system clock changes. - - This routine can be called by an application when it - receives a WM_TIMECHANGE message from the system. At present - it broadcasts all condition variables so that waiting threads - can wake up and re-evaluate their conditions and restart - their timed waits if required. - - Suggested by Alexander Terekhov - - -Platform dependence -------------------- -As Win95 doesn't provide one, the library now contains -it's own InterlockedCompareExchange() routine, which is used -whenever Windows doesn't provide it. InterlockedCompareExchange() -is used to implement spinlocks and barriers, and also in mutexes. -This routine relies on the CMPXCHG machine instruction which -is not available on i386 CPUs. This library (from snapshot -20010712 onwards) is therefore no longer supported on i386 -processor platforms. - - -New standard routines ---------------------- -For source code portability only - rwlocks cannot be process shared yet. - - pthread_rwlockattr_init() - pthread_rwlockattr_destroy() - pthread_rwlockattr_setpshared() - pthread_rwlockattr_getpshared() - -As defined in the new POSIX standard, and the Single Unix Spec version 3: - - sem_timedwait() - pthread_mutex_timedlock() - Alexander Terekhov and Thomas Pfaff - pthread_rwlock_timedrdlock() - adapted from pthread_rwlock_rdlock() - pthread_rwlock_timedwrlock() - adapted from pthread_rwlock_wrlock() - - -pthread.h no longer includes windows.h --------------------------------------- -[Not yet for G++] - -This was done to prevent conflicts. - -HANDLE, DWORD, and NULL are temporarily defined within pthread.h if -they are not already. - - -pthread.h, sched.h and semaphore.h now use dllexport/dllimport --------------------------------------------------------------- -Not only to avoid the need for the pthread.def file, but to -improve performance. Apparently, declaring functions with dllimport -generates a direct call to the function and avoids the overhead -of a stub function call. - -Bug fixes ---------- -* Fixed potential NULL pointer dereferences in pthread_mutexattr_init, -pthread_mutexattr_getpshared, pthread_barrierattr_init, -pthread_barrierattr_getpshared, and pthread_condattr_getpshared. -- Scott McCaskill - -* Removed potential race condition in pthread_mutex_trylock and -pthread_mutex_lock; -- Alexander Terekhov - -* The behaviour of pthread_mutex_trylock in relation to -recursive mutexes was inconsistent with commercial implementations. -Trylock would return EBUSY if the lock was owned already by the -calling thread regardless of mutex type. Trylock now increments the -recursion count and returns 0 for RECURSIVE mutexes, and will -return EDEADLK rather than EBUSY for ERRORCHECK mutexes. This is -consistent with Solaris. -- Thomas Pfaff - -* Found a fix for the library and workaround for applications for -the known bug #2, i.e. where __CLEANUP_CXX or __CLEANUP_SEH is defined. -See the "Known Bugs in this snapshot" section below. - -This could be made transparent to applications by replacing the macros that -define the current C++ and SEH versions of pthread_cleanup_push/pop -with the C version, but AFAIK cleanup handlers would not then run in the -correct sequence with destructors and exception cleanup handlers when -an exception occurs. - -* Cancelation once started in a thread cannot now be inadvertantly -double canceled. That is, once a thread begins it's cancelation run, -cancelation is disabled and a subsequent cancel request will -return an error (ESRCH). - -* errno: An incorrect compiler directive caused a local version -of errno to be used instead of the Win32 errno. Both instances are -thread-safe but applications checking errno after a pthreads-win32 -call would be wrong. Fixing this also fixed a bad compiler -option in the testsuite (/MT should have been /MD) which is -needed to link with the correct library MSVCRT.LIB. - - -SNAPSHOT 2001-07-12 -------------------- - -To be added - - -SNAPSHOT 2001-07-03 -------------------- - -To be added - - -SNAPSHOT 2000-08-13 -------------------- - -New: -- Renamed DLL and LIB files: - pthreadVSE.dll (MS VC++/Structured EH) - pthreadVSE.lib - pthreadVCE.dll (MS VC++/C++ EH) - pthreadVCE.lib - pthreadGCE.dll (GNU G++/C++ EH) - libpthreadw32.a - - Both your application and the pthread dll should use the - same exception handling scheme. - -Bugs fixed: -- MSVC++ C++ exception handling. - -Some new tests have been added. - - -SNAPSHOT 2000-08-10 -------------------- - -New: -- asynchronous cancelation on X86 (Jason Nye) -- Makefile compatible with MS nmake to replace - buildlib.bat -- GNUmakefile for Mingw32 -- tests/Makefile for MS nmake replaces runall.bat -- tests/GNUmakefile for Mingw32 - -Bugs fixed: -- kernel32 load/free problem -- attempt to hide internel exceptions from application - exception handlers (__try/__except and try/catch blocks) -- Win32 thread handle leakage bug - (David Baggett/Paul Redondo/Eyal Lebedinsky) - -Some new tests have been added. - - -SNAPSHOT 1999-11-02 -------------------- - -Bugs fixed: -- ctime_r macro had an incorrect argument (Erik Hensema), -- threads were not being created - PTHREAD_CANCEL_DEFERRED.

See the ChangeLog file for details. - - -SNAPSHOT 1999-03-16 -------------------- - -Initial release. - +CURRENT CVS HEAD Version +RELEASE 2.9.0 pending +------------- +(2011-??-??) + +General +------- +New bug fixes in this release since 2.8.0 have NOT been applied to the +1.x.x series. + +Version 2.8.0 may be the last release for some older Windows systems. +Some changes post 2011-02-26 in CVS may not be compatible with pre +Windows 2000 systems. + +Version 1 no longer maintained +------------------------------ +The 1.x.x series is no longer maintained. However, if you really need a +version 1, the differences between 1.11.0 and 2.7.0 are very small, mainly +revolving around the pthread_once_t_ struct. Those differences applied +as a patch to the current 2.x.x should work. Don't forget to change +the version numbering in pthread.h before building. If you distribute +such a version 1.x.x please bear in mind that your numbers may clash +with those of others doing the same thing. Please consider also making +identifying changes in version.rc to differentiate your build. + +Testing and verification +------------------------ +The current CVS head version has been tested on an SMP architecture +(AMD Phenom 9750 Quad Core) by running the MinGW32 (GCC) builds against +the full test suite, stress tests and benchmarks. + +New Features +------------ +(MSC and GNU builds) The statically linked library now automatically +initialises and cleans up on program start/exit, i.e. statically linked +applications need not call the routines pthread_win32_process_attach_np() +and pthread_win32_process_detach_np() explicitly. The per-thread routine +pthread_win32_thread_detach_np() is also called at program exit to cleanup +POSIX resources acquired by the primary Windows native thread (if I (RJ) +understand the process correctly). Other Windows native threads that call +POSIX API routines may need to call the thread detach routine on thread +exit if the application depends on reclaimed POSIX resources or running +POSIX TSD (TLS) destructors. +See README.NONPORTABLE for descriptions of these routines. +- Ramiro Polla + +Robust mutexes are implemented within the PROCESS_PRIVATE scope. NOTE that +pthread_mutex_* functions may return different error codes for robust +mutexes than they otherwise do in normal usage, e.g. pthread_mutex_unlock +is required to check ownership for all mutex types when the mutex is +robust, whereas this does not occur for the "normal" non-robust mutex type. +- Ross Johnson + +pthread_getunique_np is implemented for source level compatibility +with some other implementations. This routine returns a 64 bit +sequence number that is uniquely associated with a thread. It can be +used by applications to order or hash POSIX thread handles. +- Ross Johnson + +Bug fixes +--------- +Many more changes for 64 bit systems. +- Kai Tietz + +Various modifications and fixes to build and test for WinCE. +- Marcel Ruff, Sinan Kaya + +Fix pthread_cond_destroy() - should not be a cancellation point. Other +minor build problems fixed. +- Romano Paolo Tenca + +Remove potential deadlock condition from pthread_cond_destroy(). +- Eric Berge + +Various modifications to build and test for Win64. +- Kip Streithorst + +Various fixes to the QueueUserAPCEx async cancellation helper DLL +(this is a separate download) and pthreads code cleanups. +- Sebastian Gottschalk + +Removed potential NULL pointer reference. +- Robert Kindred + +Removed the requirement that applications restrict the number of threads +calling pthread_barrier_wait to just the barrier count. Also reduced the +contention between barrier_wait and barrier_destroy. This change will have +slowed barriers down slightly but halves the number of semaphores consumed +per barrier to one. +- Ross Johnson + +Fixed a handle leak in sched_[gs]etscheduler. +- Mark Pizzolato + +Removed all of the POSIX re-entrant function compatibility macros from pthread.h. +Some were simply not semanticly correct. +- Igor Lubashev + +Threads no longer attempt to pass uncaught exceptions out of thread scope (C++ +and SEH builds only). Uncaught exceptions now cause the thread to exit with +the return code PTHREAD_CANCELED. +- Ross Johnson + +Lots of casting fixes particularly for x64, Interlocked fixes and reworking +for x64. +- Daniel Richard G., John Kamp + +Other changes +------------- +Dependence on the winsock library is now discretionary via +#define RETAIN_WSALASTERROR in config.h. It is undefined by default unless +WINCE is defined (because RJ is unsure of the dependency there). +- Ramiro Polla + +Several static POSIX mutexes used for internal management were replaced by +MCS queue-based locks to reduce resource consumption, in particular use of Win32 +objects. +- Ross Johnson + +For security, the QuserEx.dll if used must now be installed in the Windows System +folder. +- Ross Johnson + +New tests +--------- +robust[1-5].c - Robust mutexes +sequence1.c - per-thread unique sequence numbers + +Modified tests and benchtests +----------------------------- +All mutex*.c tests wherever appropriate have been modified to also test +robust mutexes under the same conditions. +Added robust mutex benchtests to benchtest*.c wherever appropriate. + + +RELEASE 2.8.0 +------------- +(2006-12-22) + +General +------- +New bug fixes in this release since 2.7.0 have not been applied to the +version 1.x.x series. It is probably time to drop version 1. + +Testing and verification +------------------------ +This release has not yet been tested on SMP architechtures. All tests pass +on a uni-processor system. + +Bug fixes +--------- +Sem_destroy could return EBUSY even though no threads were waiting on the +semaphore. Other races around invalidating semaphore structs (internally) +have been removed as well. + +New tests +--------- +semaphore5.c - tests the bug fix referred to above. + + +RELEASE 2.7.0 +------------- +(2005-06-04) + +General +------- +All new features in this release have been back-ported in release 1.11.0, +including the incorporation of MCS locks in pthread_once, however, versions +1 and 2 remain incompatible even though they are now identical in +performance and functionality. + +Testing and verification +------------------------ +This release has been tested (passed the test suite) on both uni-processor +and multi-processor systems. +- Tim Theisen + +Bug fixes +--------- +Pthread_once has been re-implemented to remove priority boosting and other +complexity to improve robustness. Races for Win32 handles that are not +recycle-unique have been removed. The general form of pthread_once is now +the same as that suggested earlier by Alexander Terekhov, but instead of the +'named mutex', a queue-based lock has been implemented which has the required +properties of dynamic self initialisation and destruction. This lock is also +efficient. The ABI is unaffected in as much as the size of pthread_once_t has +not changed and PTHREAD_ONCE_INIT has not changed, however, applications that +peek inside pthread_once_t, which is supposed to be opaque, will break. +- Vladimir Kliatchko + +New features +------------ +* Support for Mingw cross development tools added to GNUmakefile. +Mingw cross tools allow building the libraries on Linux. +- Mikael Magnusson + + +RELEASE 2.6.0 +------------- +(2005-05-19) + +General +------- +All of the bug fixes and new features in this release have been +back-ported in release 1.10.0. + +Testing and verification +------------------------ +This release has been tested (passed the test suite) on both uni-processor +and multi-processor systems. Thanks to Tim Theisen at TomoTherapy for +exhaustively running the MP tests and for providing crutial observations +and data when faults are detected. + +Bugs fixed +---------- + +* pthread_detach() now reclaims remaining thread resources if called after +the target thread has terminated. Previously, this routine did nothing in +this case. + +New tests +--------- + +* detach1.c - tests that pthread_detach properly invalidates the target +thread, which indicates that the thread resources have been reclaimed. + + +RELEASE 2.5.0 +------------- +(2005-05-09) + +General +------- + +The package now includes a reference documentation set consisting of +HTML formatted Unix-style manual pages that have been edited for +consistency with Pthreads-w32. The set can also be read online at: +http://sources.redhat.com/pthreads-win32/manual/index.html + +Thanks again to Tim Theisen for running the test suite pre-release +on an MP system. + +All of the bug fixes and new features in this release have been +back-ported in release 1.9.0. + +Bugs fixed +---------- + +* Thread Specific Data (TSD) key management has been ammended to +eliminate a source of (what was effectively) resource leakage (a HANDLE +plus memory for each key destruct routine/thread association). This was +not a true leak because these resources were eventually reclaimed when +pthread_key_delete was run AND each thread referencing the key had exited. +The problem was that these two conditions are often not met until very +late, and often not until the process is about to exit. + +The ammended implementation avoids the need for the problematic HANDLE +and reclaims the memory as soon as either the key is deleted OR the +thread exits, whichever is first. + +Thanks to Richard Hughes at Aculab for identifying and locating the leak. + +* TSD key destructors are now processed up to PTHREAD_DESTRUCTOR_ITERATIONS +times instead of just once. PTHREAD_DESTRUCTOR_ITERATIONS has been +defined in pthread.h for some time but not used. + +* Fix a semaphore accounting race between sem_post/sem_post_multiple +and sem_wait cancellation. This is the same issue as with +sem_timedwait that was fixed in the last release. + +* sem_init, sem_post, and sem_post_multiple now check that the +semaphore count never exceeds _POSIX_SEM_VALUE_MAX. + +* Although sigwait() is nothing more than a no-op, it should at least +be a cancellation point to be consistent with the standard. + +New tests +--------- + +* stress1.c - attempts to expose problems in condition variable +and semaphore timed wait logic. This test was inspired by Stephan +Mueller's sample test code used to identify the sem_timedwait bug +from the last release. It's not a part of the regular test suite +because it can take awhile to run. To run it: +nmake clean VC-stress + +* tsd2.c - tests that key destructors are re-run if the tsd key value is +not NULL after the destructor routine has run. Also tests that +pthread_setspecific() and pthread_getspecific() are callable from +destructors. + + +RELEASE 2.4.0 +------------- +(2005-04-26) + +General +------- + +There is now no plan to release a version 3.0.0 to fix problems in +pthread_once(). Other possible implementations of pthread_once +will still be investigated for a possible future release in an attempt +to reduce the current implementation's complexity. + +All of the bug fixes and new features in this release have been +back-ported for release 1.8.0. + +Bugs fixed +---------- + +* Fixed pthread_once race (failures on an MP system). Thanks to +Tim Theisen for running exhaustive pre-release testing on his MP system +using a range of compilers: + VC++ 6 + VC++ 7.1 + Intel C++ version 8.0 +All tests passed. +Some minor speed improvements were also done. + +* Fix integer overrun error in pthread_mutex_timedlock() - missed when +sem_timedwait() was fixed in release 2.2.0. This routine no longer returns +ENOTSUP when NEED_SEM is defined - it is supported (NEED_SEM is only +required for WinCE versions prior to 3.0). + +* Fix timeout bug in sem_timedwait(). +- Thanks to Stephan Mueller for reporting, providing diagnostic output +and test code. + +* Fix several problems in the NEED_SEM conditionally included code. +NEED_SEM included code is provided for systems that don't implement W32 +semaphores, such as WinCE prior to version 3.0. An alternate implementation +of POSIX semaphores is built using W32 events for these systems when +NEED_SEM is defined. This code has been completely rewritten in this +release to reuse most of the default POSIX semaphore code, and particularly, +to implement all of the sem_* routines supported by pthreads-win32. Tim +Theisen also run the test suite over the NEED_SEM code on his MP system. All +tests passed. + +* The library now builds without errors for the Borland Builder 5.5 compiler. + +New features +------------ + +* pthread_mutex_timedlock() and all sem_* routines provided by +pthreads-win32 are now implemented for WinCE versions prior to 3.0. Those +versions did not implement W32 semaphores. Define NEED_SEM in config.h when +building the library for these systems. + +Known issues in this release +---------------------------- + +* pthread_once is too complicated - but it works as far as testing can +determine.. + +* The Borland version of the dll fails some of the tests with a memory read +exception. The cause is not yet known but a compiler bug has not been ruled +out. + + +RELEASE 2.3.0 +------------- +(2005-04-12) + +General +------- + +Release 1.7.0 is a backport of features and bug fixes new in +this release. See earlier notes under Release 2.0.0/General. + +Bugs fixed +---------- + +* Fixed pthread_once potential for post once_routine cancellation +hanging due to starvation. See comments in pthread_once.c. +Momentary priority boosting is used to ensure that, after a +once_routine is cancelled, the thread that will run the +once_routine is not starved by higher priority waiting threads at +critical times. Priority boosting occurs only AFTER a once_routine +cancellation, and is applied only to that once_control. The +once_routine is run at the thread's normal base priority. + +New tests +--------- + +* once4.c: Aggressively tests pthread_once() under realtime +conditions using threads with varying priorities. Windows' +random priority boosting does not occur for threads with realtime +priority levels. + + +RELEASE 2.2.0 +------------- +(2005-04-04) + +General +------- + +* Added makefile targets to build static link versions of the library. +Both MinGW and MSVC. Please note that this does not imply any change +to the LGPL licensing, which still imposes psecific conditions on +distributing software that has been statically linked with this library. + +* There is a known bug in pthread_once(). Cancellation of the init_routine +exposes a potential starvation (i.e. deadlock) problem if a waiting thread +has a higher priority than the initting thread. This problem will be fixed +in version 3.0.0 of the library. + +Bugs fixed +---------- + +* Fix integer overrun error in sem_timedwait(). +Kevin Lussier + +* Fix preprocessor directives for static linking. +Dimitar Panayotov + + +RELEASE 2.1.0 +------------- +(2005-03-16) + +Bugs fixed +---------- + +* Reverse change to pthread_setcancelstate() in 2.0.0. + + +RELEASE 2.0.0 +------------- +(2005-03-16) + +General +------- + +This release represents an ABI change and the DLL version naming has +incremented from 1 to 2, e.g. pthreadVC2.dll. + +Version 1.4.0 back-ports the new functionality included in this +release. Please distribute DLLs built from that version with updates +to applications built on pthreads-win32 version 1.x.x. + +The package naming has changed, replacing the snapshot date with +the version number + descriptive information. E.g. this +release is "pthreads-w32-2-0-0-release". + +Bugs fixed +---------- + +* pthread_setcancelstate() no longer checks for a pending +async cancel event if the library is using alertable async +cancel.

DLL versioning has also been included to allow +applications to runtime check the Microsoft compatible DLL version +information, and to extend the DLL naming system for ABI and major +(non-backward compatible) API changes. See the README file for details. + +Bug fixes +--------- + +* Condition variables no longer deadlock (bug introduced in +snapshot-2004-11-03). +- Alexander Kotliarov and Nicolas at saintmac + +* DLL naming extended to avoid 'DLL hell' in the future, and to +accommodate the ABI change introduced in snapshot-2004-11-03. Snapshot +2004-11-03 will be removed from FTP sites. + +New features +------------ + +* A Microsoft-style version resource has been added to the DLL for +applications that wish to check DLL compatibility at runtime. + +* Pthreads-win32 DLL naming has been extended to allow incompatible DLL +versions to co-exist in the same filesystem. See the README file for details, +but briefly: while the version information inside the DLL will change with +each release from now on, the DLL version names will only change if the new +DLL is not backward compatible with older applications. + +The versioning scheme has been borrowed from GNU Libtool, and the DLL +naming scheme is from Cygwin. Provided the Libtool-style numbering rules are +honoured, the Cygwin DLL naming scheme automatcally ensures that DLL name +changes are minimal and that applications will not load an incompatible +pthreads-win32 DLL. + +Those who use the pre-built DLLs will find that the DLL/LIB names have a new +suffix (1) in this snapshot. E.g. pthreadVC1.dll etc. + +* The POSIX thread ID reuse uniqueness feature introduced in the last snapshot +has been kept as default, but the behaviour can now be controlled when the DLL +is built to effectively switch it off. This makes the library much more +sensitive to applications that assume that POSIX thread IDs are unique, i.e. +are not strictly compliant with POSIX. See the PTW32_THREAD_ID_REUSE_INCREMENT +macro comments in config.h for details. + +Other changes +------------- +Certain POSIX macros have changed. + +These changes are intended to conform to the Single Unix Specification version 3, +which states that, if set to 0 (zero) or not defined, then applications may use +sysconf() to determine their values at runtime. Pthreads-win32 does not +implement sysconf(). + +The following macros are no longer undefined, but defined and set to -1 +(not implemented): + + _POSIX_THREAD_ATTR_STACKADDR + _POSIX_THREAD_PRIO_INHERIT + _POSIX_THREAD_PRIO_PROTECT + _POSIX_THREAD_PROCESS_SHARED + +The following macros are defined and set to 200112L (implemented): + + _POSIX_THREADS + _POSIX_THREAD_SAFE_FUNCTIONS + _POSIX_THREAD_ATTR_STACKSIZE + _POSIX_THREAD_PRIORITY_SCHEDULING + _POSIX_SEMAPHORES + _POSIX_READER_WRITER_LOCKS + _POSIX_SPIN_LOCKS + _POSIX_BARRIERS + +The following macros are defined and set to appropriate values: + + _POSIX_THREAD_THREADS_MAX + _POSIX_SEM_VALUE_MAX + _POSIX_SEM_NSEMS_MAX + PTHREAD_DESTRUCTOR_ITERATIONS + PTHREAD_KEYS_MAX + PTHREAD_STACK_MIN + PTHREAD_THREADS_MAX + + +SNAPSHOT 2004-11-03 +------------------- + +DLLs produced from this snapshot cannot be used with older applications without +recompiling the application, due to a change to pthread_t to provide unique POSIX +thread IDs. + +Although this snapshot passes the extended test suite, many of the changes are +fairly major, and some applications may show different behaviour than previously, +so adopt with care. Hopefully, any changed behaviour will be due to the library +being better at it's job, not worse. + +Bug fixes +--------- + +* pthread_create() no longer accepts NULL as the thread reference arg. +A segfault (memory access fault) will result, and no thread will be +created. + +* pthread_barrier_wait() no longer acts as a cancelation point. + +* Fix potential race condition in pthread_once() +- Tristan Savatier + +* Changes to pthread_cond_destroy() exposed some coding weaknesses in several +test suite mini-apps because pthread_cond_destroy() now returns EBUSY if the CV +is still in use. + +New features +------------ + +* Added for compatibility: +PTHREAD_RECURSIVE_MUTEX_INITIALIZER, +PTHREAD_ERRORCHECK_MUTEX_INITIALIZER, +PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP, +PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP + +* Initial support for Digital Mars compiler +- Anuj Goyal + +* Faster Mutexes. These have been been rewritten following a model provided by +Alexander Terekhov that reduces kernel space checks, and eliminates some additional +critical sections used to manage a race between timedlock expiration and unlock. +Please be aware that the new mutexes do not enforce strict absolute FIFO scheduling +of mutexes, however any out-of-order lock acquisition should be very rare. + +* Faster semaphores. Following a similar model to mutexes above, these have been +rewritten to use preliminary users space checks. + +* sem_getvalue() now returns the number of waiters. + +* The POSIX thread ID now has much stronger uniqueness characteristics. The library +garrantees not to reuse the same thread ID for at least 2^(wordsize) thread +destruction/creation cycles. + +New tests +--------- + +* semaphore4.c: Tests cancelation of the new sem_wait(). + +* semaphore4t.c: Likewise for sem_timedwait(). + +* rwlock8.c: Tests and times the slow execution paths of r/w locks, and the CVs, +mutexes, and semaphores that they're built on. + + +SNAPSHOT 2004-05-16 +------------------- + +Attempt to add Watcom to the list of compilers that can build the library. +This failed in the end due to it's non-thread-aware errno. The library +builds but the test suite fails. See README.Watcom for more details. + +Bug fixes +--------- +* Bug and memory leak in sem_init() +- Alex Blanco + +* ptw32_getprocessors() now returns CPU count of 1 for WinCE. +- James Ewing + +* pthread_cond_wait() could be canceled at a point where it should not +be cancelable. Fixed. +- Alexander Terekhov + +* sem_timedwait() had an incorrect timeout calculation. +- Philippe Di Cristo + +* Fix a memory leak left behind after threads are destroyed. +- P. van Bruggen + +New features +------------ +* Ported to AMD64. +- Makoto Kato + +* True pre-emptive asynchronous cancelation of threads. This is optional +and requires that Panagiotis E. Hadjidoukas's QueueUserAPCEx package be +installed. This package is included in the pthreads-win32 self-unpacking +Zip archive starting from this snapshot. See the README.txt file inside +the package for installation details. + +Note: If you don't use async cancelation in your application, or don't need +to cancel threads that are blocked on system resources such as network I/O, +then the default non-preemptive async cancelation is probably good enough. +However, pthreads-win32 auto-detects the availability of these components +at run-time, so you don't need to rebuild the library from source if you +change your mind later. + +All of the advice available in books and elsewhere on the undesirability +of using async cancelation in any application still stands, but this +feature is a welcome addition with respect to the library's conformance to +the POSIX standard. + +SNAPSHOT 2003-09-18 +------------------- + +Cleanup of thread priority management. In particular, setting of thread +priority now attempts to map invalid Win32 values within the range returned +by sched_get_priority_min/max() to useful values. See README.NONPORTABLE +under "Thread priority". + +Bug fixes +--------- +* pthread_getschedparam() now returns the priority given by the most recent +call to pthread_setschedparam() or established by pthread_create(), as +required by the standard. Previously, pthread_getschedparam() incorrectly +returned the running thread priority at the time of the call, which may have +been adjusted or temporarily promoted/demoted. + +* sched_get_priority_min() and sched_get_priority_max() now return -1 on error +and set errno. Previously, they incorrectly returned the error value directly. + + +SNAPSHOT 2003-09-04 +------------------- + +Bug fixes +--------- +* ptw32_cancelableWait() now allows cancelation of waiting implicit POSIX +threads. + +New test +-------- +* cancel8.c tests cancelation of Win32 threads waiting at a POSIX cancelation +point. + + +SNAPSHOT 2003-09-03 +------------------- + +Bug fixes +--------- +* pthread_self() would free the newly created implicit POSIX thread handle if +DuplicateHandle failed instead of recycle it (very unlikely). + +* pthread_exit() was neither freeing nor recycling the POSIX thread struct +for implicit POSIX threads. + +New feature - Cancelation of/by Win32 (non-POSIX) threads +--------------------------------------------------------- +Since John Bossom's original implementation, the library has allowed non-POSIX +initialised threads (Win32 threads) to call pthreads-win32 routines and +therefore interact with POSIX threads. This is done by creating an on-the-fly +POSIX thread ID for the Win32 thread that, once created, allows fully +reciprical interaction. This did not extend to thread cancelation (async or +deferred). Now it does. + +Any thread can be canceled by any other thread (Win32 or POSIX) if the former +thread's POSIX pthread_t value is known. It's TSD destructors and POSIX +cleanup handlers will be run before the thread exits with an exit code of +PTHREAD_CANCELED (retrieved with GetExitCodeThread()). + +This allows a Win32 thread to, for example, call POSIX CV routines in the same way +that POSIX threads would/should, with pthread_cond_wait() cancelability and +cleanup handlers (pthread_cond_wait() is a POSIX cancelation point). + +By adding cancelation, Win32 threads should now be able to call all POSIX +threads routines that make sense including semaphores, mutexes, condition +variables, read/write locks, barriers, spinlocks, tsd, cleanup push/pop, +cancelation, pthread_exit, scheduling, etc. + +Note that these on-the-fly 'implicit' POSIX thread IDs are initialised as detached +(not joinable) with deferred cancelation type. The POSIX thread ID will be created +automatically by any POSIX routines that need a POSIX handle (unless the routine +needs a pthread_t as a parameter of course). A Win32 thread can discover it's own +POSIX thread ID by calling pthread_self(), which will create the handle if +necessary and return the pthread_t value. + +New tests +--------- +Test the above new feature. + + +SNAPSHOT 2003-08-19 +------------------- + +This snapshot fixes some accidental corruption to new test case sources. +There are no changes to the library source code. + + +SNAPSHOT 2003-08-15 +------------------- + +Bug fixes +--------- + +* pthread.dsp now uses correct compile flags (/MD). +- Viv + +* pthread_win32_process_detach_np() fixed memory leak. +- Steven Reddie + +* pthread_mutex_destroy() fixed incorrect return code. +- Nicolas Barry + +* pthread_spin_destroy() fixed memory leak. +- Piet van Bruggen + +* Various changes to tighten arg checking, and to work with later versions of +MinGW32 and MsysDTK. + +* pthread_getschedparam() etc, fixed dangerous thread validity checking. +- Nicolas Barry + +* POSIX thread handles are now reused and their memory is not freed on thread exit. +This allows for stronger thread validity checking. + +New standard routine +-------------------- + +* pthread_kill() added to provide thread validity checking to applications. +It does not accept any non zero values for the signal arg. + +New test cases +-------------- + +* New test cases to confirm validity checking, pthread_kill(), and thread reuse. + + +SNAPSHOT 2003-05-10 +------------------- + +Bug fixes +--------- + +* pthread_mutex_trylock() now returns correct error values. +pthread_mutex_destroy() will no longer destroy a recursively locked mutex. +pthread_mutex_lock() is no longer inadvertantly behaving as a cancelation point. +- Thomas Pfaff + +* pthread_mutex_timedlock() no longer occasionally sets incorrect mutex +ownership, causing deadlocks in some applications. +- Robert Strycek and Alexander Terekhov + + +SNAPSHOT 2002-11-04 +------------------- + +Bug fixes +--------- + +* sem_getvalue() now returns the correct value under Win NT and WinCE. +- Rob Fanner + +* sem_timedwait() now uses tighter checks for unreasonable +abstime values - that would result in unexpected timeout values. + +* ptw32_cond_wait_cleanup() no longer mysteriously consumes +CV signals but may produce more spurious wakeups. It is believed +that the sem_timedwait() call is consuming a CV signal that it +shouldn't. +- Alexander Terekhov + +* Fixed a memory leak in ptw32_threadDestroy() for implicit threads. + +* Fixed potential for deadlock in pthread_cond_destroy(). +A deadlock could occur for statically declared CVs (PTHREAD_COND_INITIALIZER), +when one thread is attempting to destroy the condition variable while another +is attempting to dynamically initialize it. +- Michael Johnson + + +SNAPSHOT 2002-03-02 +------------------- + +Cleanup code default style. (IMPORTANT) +---------------------------------------------------------------------- +Previously, if not defined, the cleanup style was determined automatically +from the compiler/language, and one of the following was defined accordingly: + + __CLEANUP_SEH MSVC only + __CLEANUP_CXX C++, including MSVC++, GNU G++ + __CLEANUP_C C, including GNU GCC, not MSVC + +These defines determine the style of cleanup (see pthread.h) and, +most importantly, the way that cancelation and thread exit (via +pthread_exit) is performed (see the routine ptw32_throw() in private.c). + +In short, the exceptions versions of the library throw an exception +when a thread is canceled or exits (via pthread_exit()), which is +caught by a handler in the thread startup routine, so that the +the correct stack unwinding occurs regardless of where the thread +is when it's canceled or exits via pthread_exit(). + +In this and future snapshots, unless the build explicitly defines (e.g. +via a compiler option) __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then +the build NOW always defaults to __CLEANUP_C style cleanup. This style +uses setjmp/longjmp in the cancelation and pthread_exit implementations, +and therefore won't do stack unwinding even when linked to applications +that have it (e.g. C++ apps). This is for consistency with most +current commercial Unix POSIX threads implementations. Compaq's TRU64 +may be an exception (no pun intended) and possible future trend. + +Although it was not clearly documented before, it is still necessary to +build your application using the same __CLEANUP_* define as was +used for the version of the library that you link with, so that the +correct parts of pthread.h are included. That is, the possible +defines require the following library versions: + + __CLEANUP_SEH pthreadVSE.dll + __CLEANUP_CXX pthreadVCE.dll or pthreadGCE.dll + __CLEANUP_C pthreadVC.dll or pthreadGC.dll + +E.g. regardless of whether your app is C or C++, if you link with +pthreadVC.lib or libpthreadGC.a, then you must define __CLEANUP_C. + + +THE POINT OF ALL THIS IS: if you have not been defining one of these +explicitly, then the defaults as described at the top of this +section were being used. + +THIS NOW CHANGES, as has been explained above, but to try to make this +clearer here's an example: + +If you were building your application with MSVC++ i.e. using C++ +exceptions and not explicitly defining one of __CLEANUP_*, then +__CLEANUP_C++ was automatically defined for you in pthread.h. +You should have been linking with pthreadVCE.dll, which does +stack unwinding. + +If you now build your application as you had before, pthread.h will now +automatically set __CLEANUP_C as the default style, and you will need to +link with pthreadVC.dll. Stack unwinding will now NOT occur when a thread +is canceled, or the thread calls pthread_exit(). + +Your application will now most likely behave differently to previous +versions, and in non-obvious ways. Most likely is that locally +instantiated objects may not be destroyed or cleaned up after a thread +is canceled. + +If you want the same behaviour as before, then you must now define +__CLEANUP_C++ explicitly using a compiler option and link with +pthreadVCE.dll as you did before. + + +WHY ARE WE MAKING THE DEFAULT STYLE LESS EXCEPTION-FRIENDLY? +Because no commercial Unix POSIX threads implementation allows you to +choose to have stack unwinding. Therefore, providing it in pthread-win32 +as a default is dangerous. We still provide the choice but unless +you consciously choose to do otherwise, your pthreads applications will +now run or crash in similar ways irrespective of the threads platform +you use. Or at least this is the hope. + + +WHY NOT REMOVE THE EXCEPTIONS VERSIONS OF THE LIBRARY ALTOGETHER? +There are a few reasons: +- because there are well respected POSIX threads people who believe + that POSIX threads implementations should be exceptions aware and + do the expected thing in that context. (There are equally respected + people who believe it should not be easily accessible, if it's there + at all, for unconditional conformity to other implementations.) +- because pthreads-win32 is one of the few implementations that has + the choice, perhaps the only freely available one, and so offers + a laboratory to people who may want to explore the effects; +- although the code will always be around somewhere for anyone who + wants it, once it's removed from the current version it will not be + nearly as visible to people who may have a use for it. + + +Source module splitting +----------------------- +In order to enable smaller image sizes to be generated +for applications that link statically with the library, +most routines have been separated out into individual +source code files. + +This is being done in such a way as to be backward compatible. +The old source files are reused to congregate the individual +routine files into larger translation units (via a bunch of +# includes) so that the compiler can still optimise wherever +possible, e.g. through inlining, which can only be done +within the same translation unit. + +It is also possible to build the entire library by compiling +the single file named "pthread.c", which just #includes all +the secondary congregation source files. The compiler +may be able to use this to do more inlining of routines. + +Although the GNU compiler is able to produce libraries with +the necessary separation (the -ffunction-segments switch), +AFAIK, the MSVC and other compilers don't have this feature. + +Finally, since I use makefiles and command-line compilation, +I don't know what havoc this reorganisation may wreak amongst +IDE project file users. You should be able to continue +using your existing project files without modification. + + +New non-portable functions +-------------------------- +pthread_num_processors_np(): + Returns the number of processors in the system that are + available to the process, as determined from the processor + affinity mask. + +pthread_timechange_handler_np(): + To improve tolerance against operator or time service initiated + system clock changes. + + This routine can be called by an application when it + receives a WM_TIMECHANGE message from the system. At present + it broadcasts all condition variables so that waiting threads + can wake up and re-evaluate their conditions and restart + their timed waits if required. + - Suggested by Alexander Terekhov + + +Platform dependence +------------------- +As Win95 doesn't provide one, the library now contains +it's own InterlockedCompareExchange() routine, which is used +whenever Windows doesn't provide it. InterlockedCompareExchange() +is used to implement spinlocks and barriers, and also in mutexes. +This routine relies on the CMPXCHG machine instruction which +is not available on i386 CPUs. This library (from snapshot +20010712 onwards) is therefore no longer supported on i386 +processor platforms. + + +New standard routines +--------------------- +For source code portability only - rwlocks cannot be process shared yet. + + pthread_rwlockattr_init() + pthread_rwlockattr_destroy() + pthread_rwlockattr_setpshared() + pthread_rwlockattr_getpshared() + +As defined in the new POSIX standard, and the Single Unix Spec version 3: + + sem_timedwait() + pthread_mutex_timedlock() - Alexander Terekhov and Thomas Pfaff + pthread_rwlock_timedrdlock() - adapted from pthread_rwlock_rdlock() + pthread_rwlock_timedwrlock() - adapted from pthread_rwlock_wrlock() + + +pthread.h no longer includes windows.h +-------------------------------------- +[Not yet for G++] + +This was done to prevent conflicts. + +HANDLE, DWORD, and NULL are temporarily defined within pthread.h if +they are not already. + + +pthread.h, sched.h and semaphore.h now use dllexport/dllimport +-------------------------------------------------------------- +Not only to avoid the need for the pthread.def file, but to +improve performance. Apparently, declaring functions with dllimport +generates a direct call to the function and avoids the overhead +of a stub function call. + +Bug fixes +--------- +* Fixed potential NULL pointer dereferences in pthread_mutexattr_init, +pthread_mutexattr_getpshared, pthread_barrierattr_init, +pthread_barrierattr_getpshared, and pthread_condattr_getpshared. +- Scott McCaskill + +* Removed potential race condition in pthread_mutex_trylock and +pthread_mutex_lock; +- Alexander Terekhov + +* The behaviour of pthread_mutex_trylock in relation to +recursive mutexes was inconsistent with commercial implementations. +Trylock would return EBUSY if the lock was owned already by the +calling thread regardless of mutex type. Trylock now increments the +recursion count and returns 0 for RECURSIVE mutexes, and will +return EDEADLK rather than EBUSY for ERRORCHECK mutexes. This is +consistent with Solaris. +- Thomas Pfaff + +* Found a fix for the library and workaround for applications for +the known bug #2, i.e. where __CLEANUP_CXX or __CLEANUP_SEH is defined. +See the "Known Bugs in this snapshot" section below. + +This could be made transparent to applications by replacing the macros that +define the current C++ and SEH versions of pthread_cleanup_push/pop +with the C version, but AFAIK cleanup handlers would not then run in the +correct sequence with destructors and exception cleanup handlers when +an exception occurs. + +* Cancelation once started in a thread cannot now be inadvertantly +double canceled. That is, once a thread begins it's cancelation run, +cancelation is disabled and a subsequent cancel request will +return an error (ESRCH). + +* errno: An incorrect compiler directive caused a local version +of errno to be used instead of the Win32 errno. Both instances are +thread-safe but applications checking errno after a pthreads-win32 +call would be wrong. Fixing this also fixed a bad compiler +option in the testsuite (/MT should have been /MD) which is +needed to link with the correct library MSVCRT.LIB. + + +SNAPSHOT 2001-07-12 +------------------- + +To be added + + +SNAPSHOT 2001-07-03 +------------------- + +To be added + + +SNAPSHOT 2000-08-13 +------------------- + +New: +- Renamed DLL and LIB files: + pthreadVSE.dll (MS VC++/Structured EH) + pthreadVSE.lib + pthreadVCE.dll (MS VC++/C++ EH) + pthreadVCE.lib + pthreadGCE.dll (GNU G++/C++ EH) + libpthreadw32.a + + Both your application and the pthread dll should use the + same exception handling scheme. + +Bugs fixed: +- MSVC++ C++ exception handling. + +Some new tests have been added. + + +SNAPSHOT 2000-08-10 +------------------- + +New: +- asynchronous cancelation on X86 (Jason Nye) +- Makefile compatible with MS nmake to replace + buildlib.bat +- GNUmakefile for Mingw32 +- tests/Makefile for MS nmake replaces runall.bat +- tests/GNUmakefile for Mingw32 + +Bugs fixed: +- kernel32 load/free problem +- attempt to hide internel exceptions from application + exception handlers (__try/__except and try/catch blocks) +- Win32 thread handle leakage bug + (David Baggett/Paul Redondo/Eyal Lebedinsky) + +Some new tests have been added. + + +SNAPSHOT 1999-11-02 +------------------- + +Bugs fixed: +- ctime_r macro had an incorrect argument (Erik Hensema), +- threads were not being created + PTHREAD_CANCEL_DEFERRED.

You must use +the API function pthread_equal() to test for equality. + +3) Never attempt to reference individual members. + + +The problem + +Certain applications would like to be able to access only the 'pure' pthread_t +id values, primarily to use as keys into data structures to manage threads or +thread-related data, but this is not possible in a maximally portable and +standards compliant way for current POSIX threads implementations. + +For implementations that define pthread_t as a scalar, programmers often employ +direct relational and equality operators on pthread_t. This code will break when +ported to an implementation that defines pthread_t as an aggregate type. + +For implementations that define pthread_t as an aggregate, e.g. a struct, +programmers can use memcmp etc., but then face the prospect that the struct may +include alignment padding bytes or bits as well as extra implementation-specific +members that are not part of the unique identifying value. + +[While this is not currently the case for pthreads-win32, opacity also +means that an implementation is free to change the definition, which should +generally only require that applications be recompiled and relinked, not +rewritten.] + + +Doesn't the compiler take care of padding? + +The C89 and later standards only effectively guarrantee element-by-element +equivalence following an assignment or pass by value of a struct or union, +therefore undefined areas of any two otherwise equivalent pthread_t instances +can still compare differently, e.g. attempting to compare two such pthread_t +variables byte-by-byte, e.g. memcmp(&t1, &t2, sizeof(pthread_t) may give an +incorrect result. In practice I'm reasonably confident that compilers routinely +also copy the padding bytes, mainly because assignment of unions would be far +too complicated otherwise. But it just isn't guarranteed by the standard. + +Illustration: + +We have two thread IDs t1 and t2 + +pthread_t t1, t2; + +In an application we create the threads and intend to store the thread IDs in an +ordered data structure (linked list, tree, etc) so we need to be able to compare +them in order to insert them initially and also to traverse. + +Suppose pthread_t contains undefined padding bits and our compiler copies our +pthread_t [struct] element-by-element, then for the assignment: + +pthread_t temp = t1; + +temp and t1 will be equivalent and correct but a byte-for-byte comparison such as +memcmp(&temp, &t1, sizeof(pthread_t)) == 0 may not return true as we expect because +the undefined bits may not have the same values in the two variable instances. + +Similarly if passing by value under the same conditions. + +If, on the other hand, the undefined bits are at least constant through every +assignment and pass-by-value then the byte-for-byte comparison +memcmp(&temp, &t1, sizeof(pthread_t)) == 0 will always return the expected result. +How can we force the behaviour we need? + + +Solutions + +Adding new functions to the standard API or as non-portable extentions is +the only reliable and portable way to provide the necessary operations. +Remember also that POSIX is not tied to the C language. The most common +functions that have been suggested are: + +pthread_null() +pthread_compare() +pthread_hash() + +A single more general purpose function could also be defined as a +basis for at least the last two of the above functions. + +First we need to list the freedoms and constraints with restpect +to pthread_t so that we can be sure our solution is compatible with the +standard. + +What is known or may be deduced from the standard: +1) pthread_t must be able to be passed by value, so it must be a single object. +2) from (1) it must be copyable so cannot embed thread-state information, locks +or other volatile objects required to manage the thread it associates with. +3) pthread_t may carry additional information, e.g. for debugging or to manage +itself. +4) there is an implicit requirement that the size of pthread_t is determinable +at compile-time and size-invariant, because it must be able to copy the object +(i.e. through assignment and pass-by-value). Such copies must be genuine +duplicates, not merely a copy of a pointer to a common instance such as +would be the case if pthread_t were defined as an array. + + +Suppose we define the following function: + +/* This function shall return it's argument */ +pthread_t* pthread_normalize(pthread_t* thread); + +For scalar or aggregate pthread_t types this function would simply zero any bits +within the pthread_t that don't uniquely identify the thread, including padding, +such that client code can return consistent results from operations done on the +result. If the additional bits are a pointer to an associate structure then +this function would ensure that the memory used to store that associate +structure does not leak. After normalization the following compare would be +valid and repeatable: + +memcmp(pthread_normalize(&t1),pthread_normalize(&t2),sizeof(pthread_t)) + +Note 1: such comparisons are intended merely to order and sort pthread_t values +and allow them to index various data structures. They are not intended to reveal +anything about the relationships between threads, like startup order. + +Note 2: the normalized pthread_t is also a valid pthread_t that uniquely +identifies the same thread. + +Advantages: +1) In most existing implementations this function would reduce to a no-op that +emits no additional instructions, i.e after in-lining or optimisation, or if +defined as a macro: +#define pthread_normalise(tptr) (tptr) + +2) This single function allows an application to portably derive +application-level versions of any of the other required functions. + +3) It is a generic function that could enable unanticipated uses. + +Disadvantages: +1) Less efficient than dedicated compare or hash functions for implementations +that include significant extra non-id elements in pthread_t. + +2) Still need to be concerned about padding if copying normalized pthread_t. +See the later section on defining pthread_t to neutralise padding issues. + +Generally a pthread_t may need to be normalized every time it is used, +which could have a significant impact. However, this is a design decision +for the implementor in a competitive environment. An implementation is free +to define a pthread_t in a way that minimises or eliminates padding or +renders this function a no-op. + +Hazards: +1) Pass-by-reference directly modifies 'thread' so the application must +synchronise access or ensure that the pointer refers to a copy. The alternative +of pass-by-value/return-by-value was considered but then this requires two copy +operations, disadvantaging implementations where this function is not a no-op +in terms of speed of execution. This function is intended to be used in high +frequency situations and needs to be efficient, or at least not unnecessarily +inefficient. The alternative also sits awkwardly with functions like memcmp. + +2) [Non-compliant] code that uses relational and equality operators on +arithmetic or pointer style pthread_t types would need to be rewritten, but it +should be rewritten anyway. + + +C implementation of null/compare/hash functions using pthread_normalize(): + +/* In pthread.h */ +pthread_t* pthread_normalize(pthread_t* thread); + +/* In user code */ +/* User-level bitclear function - clear bits in loc corresponding to mask */ +void* bitclear (void* loc, void* mask, size_t count); + +typedef unsigned int hash_t; + +/* User-level hash function */ +hash_t hash(void* ptr, size_t count); + +/* + * User-level pthr_null function - modifies the origin thread handle. + * The concept of a null pthread_t is highly implementation dependent + * and this design may be far from the mark.

Could +defining pthread_t as a union rather than a struct provide a solution? + +In fact, the Linux pthread.h defines most of it's pthread_*_t objects (but not +pthread_t itself) as unions, possibly for this and/or other reasons.

Our comparisons will return consistent results and +our hashes of [zero initialised] pthread_t values will also return consistent +results. + +We have also removed the need for a pthread_null() function; we can initialise +at declaration time or easily create our own const pthread_t to use in assignments +later: + +const pthread_t null_tid = {0}; /* braces are required */ + +pthread_t t; +... +t = null_tid; + + +Note that we don't have to explicitly make use of the __size array at all.

Since all pthread_t values are generated by the library in the first +instance this need not be an application-level operation. + + +Conclusion + +I've attempted to resolve the multiple issues of type opacity and the possible +presence of undefined bits and bytes in pthread_t values, which prevent +applications from comparing or hashing pthread handles. + +Two complimentary partial solutions have been proposed, one an application-level +scheme to handle both scalar and aggregate pthread_t types equally, plus a +definition of pthread_t itself that neutralises padding bits and bytes by +coercing semantics out of the compiler to eliminate variations in the values of +padding bits. + +I have not provided any solution to the problem of handling extra values embedded +in pthread_t, e.g. debugging or trap information that an implementation is entitled +to include. Therefore none of this replaces the portability and flexibility of API +functions but what functions are needed? The threads standard is unlikely to +include that can be implemented by a combination of existing features and more +generic functions (several references in the threads rationale suggest this. +Therefore I propose that the following function could replace the several functions +that have been suggested in conversations: + +pthread_t * pthread_normalize(pthread_t * handle); + +For most existing pthreads implementations this function, or macro, would reduce to +a no-op with zero call overhead. diff --git a/pthreads/autostatic.c b/pthreads/autostatic.c index 12137a6cd..092aff2ae 100644 --- a/pthreads/autostatic.c +++ b/pthreads/autostatic.c @@ -1,69 +1,69 @@ -/* - * pthread_barrier_wait.c - * - * Description: - * This translation unit implements barrier primitives. - * - * -------------------------------------------------------------------------- - * - * Pthreads-win32 - POSIX Threads Library for Win32 - * Copyright(C) 1998 John E.

pthread_getunique_np – get the +unique sequence number associated with a thread

+

Synopsis

#include <pthread.h> +

+

unsigned long long pthread_getunique_np(pthread_t thread);

+

Description

+

Returns the unique 64 bit +sequence number assigned to thread.

+

In Pthreads-win32:

+
    +

  • the value returned is not reused after the thread terminates + so it is unique for the life of the process

    +

  • Windows native threads may obtain their own POSIX thread + sequence number by first retrieving their pthread_t handle + via pthread_self to use as the thread argument.

    +
+

This function was added for source code compatibility with some +other POSIX threads implementations.

+

Cancellation

+

None.

+

Return Value

+

pthread_getunique_np returns the unique sequence number for +thread.

+

Errors

+

None.

+

Robust Mutexes

+

If the mutex is PTHREAD_MUTEX_ROBUST and the owning thread +terminates without unlocking the mutex the implementation will wake +one waiting thread, if any. The next thread to acquire the mutex will +receive the error code EOWNERDEAD, +in which case that thread should if possible ensure that the state +protected by the mutex is consistent and then call +pthread_mutex_consistent before +unlocking. The mutex may then be used normally from then on.

+

If the thread cannot recover the +state then it must call pthread_mutex_unlock +without calling pthread_mutex_consistent. +This will mark the mutex as unusable and wake all currently waiting +threads with the return code ENOTRECOVERABLE. +The error indicates that the mutex is no longer usable and any +threads that receive this error code from any lock operation have not +acquired the mutex. The mutex can be made consistent by calling +pthread_mutex_destroy to +uninitialize the mutex, and calling pthread_mutex_int +to reinitialize the mutex. However, +the state that was protected by the mutex remains inconsistent and +some form of application recovery is required.

+

If a thread that receives the +EOWNERDEAD error code +itself terminates without unlocking the mutex then this behaviour +repeats for the next acquiring thread.

+

Applications must ensure that +they check the return values from all calls targeting robust mutexes.

+

Robust mutexes are slower because they +require some additional overhead, however they are not very much +slower than the non-robust recursive type.

Async-signal Safety

Async-signal Safety

The mutex functions are not async-signal safe. What this means is that they should not be called from a signal handler. In particular, calling pthread_mutex_lock or pthread_mutex_unlock from a signal handler may deadlock the calling thread.

pthread_mutex_init always returns 0. The other mutex functions return 0 on success and a non-zero error code on error.

Example

A shared global variable x can be protected by a mutex as follows:

-
int x;
-pthread_mutex_t mut = PTHREAD_MUTEX_INITIALIZER;
+
int x;
+pthread_mutex_t mut = PTHREAD_MUTEX_INITIALIZER;
All accesses and modifications to x should be bracketed by calls to pthread_mutex_lock and pthread_mutex_unlock as follows:
-
pthread_mutex_lock(&mut);
+
pthread_mutex_lock(&mut);
 /* operate on x */
 pthread_mutex_unlock(&mut);

For speed, Pthreads-w32 never checks the thread ownership
-of mutexes of type PTHREAD_MUTEX_NORMAL (or
+of non-robust mutexes of type PTHREAD_MUTEX_NORMAL (or
 PTHREAD_MUTEX_FAST_NP) when performing operations on the
 mutex. It is therefore possible for one thread to lock such a mutex
 and another to unlock it.

-
When developing code, it is a
-common precaution to substitute the error checking type, and drop in
-the normal type for release if the extra performance is required.

- * Module: pthread.h
- *
- * Purpose:
- *      Provides an implementation of PThreads based upon the
- *      standard:
- *
- *              POSIX 1003.1-2001
- *  and
- *    The Single Unix Specification version 3
- *
- *    (these two are equivalent)
- *
- *      in order to enhance code portability between Windows,
- *  various commercial Unix implementations, and Linux.
- *
- *      See the ANNOUNCE file for a full list of conforming
- *      routines and defined constants, and a list of missing
- *      routines and constants not defined in this implementation.
- *
- * Authors:
- *      There have been many contributors to this library.
- *      The initial implementation was contributed by
- *      John Bossom, and several others have provided major
- *      sections or revisions of parts of the implementation.
- *      Often significant effort has been contributed to
- *      find and fix important bugs and other problems to
- *      improve the reliability of the library, which sometimes
- *      is not reflected in the amount of code which changed as
- *      result.
- *      As much as possible, the contributors are acknowledged
- *      in the ChangeLog file in the source code distribution
- *      where their changes are noted in detail.
- *
- *      Contributors are listed in the CONTRIBUTORS file.
- *
- *      As usual, all bouquets go to the contributors, and all
- *      brickbats go to the project maintainer.
- *
- * Maintainer:
- *      The code base for this project is coordinated and
- *      eventually pre-tested, packaged, and made available by
- *
- *              Ross Johnson 
- *
- * QA Testers:
- *      Ultimately, the library is tested in the real world by
- *      a host of competent and demanding scientists and
- *      engineers who report bugs and/or provide solutions
- *      which are then fixed or incorporated into subsequent
- *      versions of the library. Each time a bug is fixed, a
- *      test case is written to prove the fix and ensure
- *      that later changes to the code don't reintroduce the
- *      same error. The number of test cases is slowly growing
- *      and therefore so is the code reliability.
- *
- * Compliance:
- *      See the file ANNOUNCE for the list of implemented
- *      and not-implemented routines and defined options.
- *      Of course, these are all defined is this file as well.
- *
- * Web site:
- *      The source code and other information about this library
- *      are available from
- *
- *              http://sources.redhat.com/pthreads-win32/

- * POSIX 1003.1-2001 Options
- * =========================
- *
- * Options are normally set in , which is not provided
- * with pthreads-win32.
- *
- * For conformance with the Single Unix Specification (version 3), all of the
- * options below are defined, and have a value of either -1 (not supported)
- * or 200112L (supported).
- *
- * These options can neither be left undefined nor have a value of 0, because
- * either indicates that sysconf(), which is not implemented, may be used at
- * runtime to check the status of the option.
- *
- * _POSIX_THREADS (== 200112L)
- *                      If == 200112L, you can use threads
- *
- * _POSIX_THREAD_ATTR_STACKSIZE (== 200112L)
- *                      If == 200112L, you can control the size of a thread's
- *                      stack
- *                              pthread_attr_getstacksize
- *                              pthread_attr_setstacksize
- *
- * _POSIX_THREAD_ATTR_STACKADDR (== -1)
- *                      If == 200112L, you can allocate and control a thread's
- *                      stack. If not supported, the following functions
- *                      will return ENOSYS, indicating they are not
- *                      supported:
- *                              pthread_attr_getstackaddr
- *                              pthread_attr_setstackaddr
- *
- * _POSIX_THREAD_PRIORITY_SCHEDULING (== -1)
- *                      If == 200112L, you can use realtime scheduling.
- *                      This option indicates that the behaviour of some
- *                      implemented functions conforms to the additional TPS
- *                      requirements in the standard. E.g. rwlocks favour
- *                      writers over readers when threads have equal priority.
- *
- * _POSIX_THREAD_PRIO_INHERIT (== -1)
- *                      If == 200112L, you can create priority inheritance
- *                      mutexes.

- *
- * _POSIX_THREAD_PRIO_PROTECT (== -1)
- *                      If == 200112L, you can create priority ceiling mutexes
- *                      Indicates the availability of:

- *
- * _POSIX_THREAD_PROCESS_SHARED (== -1)
- *                      If set, you can create mutexes and condition
- *                      variables that can be shared with another
- *                      process.If set, indicates the availability

- *                              pthread_condattr_setpshared
- *
- * _POSIX_THREAD_SAFE_FUNCTIONS (== 200112L)
- *                      If == 200112L you can use the special *_r library
- *                      functions that provide thread-safe behaviour
- *
- * _POSIX_READER_WRITER_LOCKS (== 200112L)
- *                      If == 200112L, you can use read/write locks
- *
- * _POSIX_SPIN_LOCKS (== 200112L)
- *                      If == 200112L, you can use spin locks
- *
- * _POSIX_BARRIERS (== 200112L)
- *                      If == 200112L, you can use barriers

+ * Module: pthread.h
+ *
+ * Purpose:
+ *      Provides an implementation of PThreads based upon the
+ *      standard:
+ *
+ *              POSIX 1003.1-2001
+ *  and
+ *    The Single Unix Specification version 3
+ *
+ *    (these two are equivalent)
+ *
+ *      in order to enhance code portability between Windows,
+ *  various commercial Unix implementations, and Linux.
+ *
+ *      See the ANNOUNCE file for a full list of conforming
+ *      routines and defined constants, and a list of missing
+ *      routines and constants not defined in this implementation.
+ *
+ * Authors:
+ *      There have been many contributors to this library.
+ *      The initial implementation was contributed by
+ *      John Bossom, and several others have provided major
+ *      sections or revisions of parts of the implementation.
+ *      Often significant effort has been contributed to
+ *      find and fix important bugs and other problems to
+ *      improve the reliability of the library, which sometimes
+ *      is not reflected in the amount of code which changed as
+ *      result.
+ *      As much as possible, the contributors are acknowledged
+ *      in the ChangeLog file in the source code distribution
+ *      where their changes are noted in detail.
+ *
+ *      Contributors are listed in the CONTRIBUTORS file.
+ *
+ *      As usual, all bouquets go to the contributors, and all
+ *      brickbats go to the project maintainer.
+ *
+ * Maintainer:
+ *      The code base for this project is coordinated and
+ *      eventually pre-tested, packaged, and made available by
+ *
+ *              Ross Johnson 
+ *
+ * QA Testers:
+ *      Ultimately, the library is tested in the real world by
+ *      a host of competent and demanding scientists and
+ *      engineers who report bugs and/or provide solutions
+ *      which are then fixed or incorporated into subsequent
+ *      versions of the library. Each time a bug is fixed, a
+ *      test case is written to prove the fix and ensure
+ *      that later changes to the code don't reintroduce the
+ *      same error. The number of test cases is slowly growing
+ *      and therefore so is the code reliability.
+ *
+ * Compliance:
+ *      See the file ANNOUNCE for the list of implemented
+ *      and not-implemented routines and defined options.
+ *      Of course, these are all defined is this file as well.
+ *
+ * Web site:
+ *      The source code and other information about this library
+ *      are available from
+ *
+ *              http://sources.redhat.com/pthreads-win32/

+ * POSIX 1003.1-2001 Options
+ * =========================
+ *
+ * Options are normally set in , which is not provided
+ * with pthreads-win32.
+ *
+ * For conformance with the Single Unix Specification (version 3), all of the
+ * options below are defined, and have a value of either -1 (not supported)
+ * or 200112L (supported).
+ *
+ * These options can neither be left undefined nor have a value of 0, because
+ * either indicates that sysconf(), which is not implemented, may be used at
+ * runtime to check the status of the option.
+ *
+ * _POSIX_THREADS (== 200112L)
+ *                      If == 200112L, you can use threads
+ *
+ * _POSIX_THREAD_ATTR_STACKSIZE (== 200112L)
+ *                      If == 200112L, you can control the size of a thread's
+ *                      stack
+ *                              pthread_attr_getstacksize
+ *                              pthread_attr_setstacksize
+ *
+ * _POSIX_THREAD_ATTR_STACKADDR (== -1)
+ *                      If == 200112L, you can allocate and control a thread's
+ *                      stack. If not supported, the following functions
+ *                      will return ENOSYS, indicating they are not
+ *                      supported:
+ *                              pthread_attr_getstackaddr
+ *                              pthread_attr_setstackaddr
+ *
+ * _POSIX_THREAD_PRIORITY_SCHEDULING (== -1)
+ *                      If == 200112L, you can use realtime scheduling.
+ *                      This option indicates that the behaviour of some
+ *                      implemented functions conforms to the additional TPS
+ *                      requirements in the standard. E.g. rwlocks favour
+ *                      writers over readers when threads have equal priority.
+ *
+ * _POSIX_THREAD_PRIO_INHERIT (== -1)
+ *                      If == 200112L, you can create priority inheritance
+ *                      mutexes.

+ *                      If == 200112L, you can create priority ceiling mutexes
+ *                      Indicates the availability of:

+ *                              pthread_mutexattr_setprotocol     +
+ *
+ * _POSIX_THREAD_PROCESS_SHARED (== -1)
+ *                      If set, you can create mutexes and condition
+ *                      variables that can be shared with another
+ *                      process.If set, indicates the availability

+ *                              pthread_condattr_setpshared
+ *
+ * _POSIX_THREAD_SAFE_FUNCTIONS (== 200112L)
+ *                      If == 200112L you can use the special *_r library
+ *                      functions that provide thread-safe behaviour
+ *
+ * _POSIX_READER_WRITER_LOCKS (== 200112L)
+ *                      If == 200112L, you can use read/write locks
+ *
+ * _POSIX_SPIN_LOCKS (== 200112L)
+ *                      If == 200112L, you can use spin locks

+ * _POSIX_BARRIERS (== 200112L)
+ *                      If == 200112L, you can use barriers
+ *
+ *      + These functions provide both 'inherit' and/or

+ * From the Sun Multi-threaded Programming Guide

+ * robustness defines the behavior when the owner of the mutex terminates without unlocking the
+ * mutex, usually because its process terminated abnormally. The value of robustness that is
+ * defined in pthread.h is PTHREAD_MUTEX_ROBUST or PTHREAD_MUTEX_STALLED. The
+ * default value is PTHREAD_MUTEX_STALLED .
+ * ■ PTHREAD_MUTEX_STALLED
+ * When the owner of the mutex terminates without unlocking the mutex, all subsequent calls
+ * to pthread_mutex_lock() are blocked from progress in an unspecified manner.
+ * ■ PTHREAD_MUTEX_ROBUST
+ * When the owner of the mutex terminates without unlocking the mutex, the mutex is
+ * unlocked. The next owner of this mutex acquires the mutex with an error return of
+ * EOWNERDEAD.
+ * Note – Your application must always check the return code from pthread_mutex_lock() for
+ * a mutex initialized with the PTHREAD_MUTEX_ROBUST attribute.
+ * ■ The new owner of this mutex should make the state protected by the mutex consistent.
+ * This state might have been left inconsistent when the previous owner terminated.
+ * ■ If the new owner is able to make the state consistent, call
+ * pthread_mutex_consistent() for the mutex before unlocking the mutex. This
+ * marks the mutex as consistent and subsequent calls to pthread_mutex_lock() and
+ * pthread_mutex_unlock() will behave in the normal manner.
+ * ■ If the new owner is not able to make the state consistent, do not call
+ * pthread_mutex_consistent() for the mutex, but unlock the mutex.
+ * All waiters are woken up and all subsequent calls to pthread_mutex_lock() fail to
+ * acquire the mutex. The return code is ENOTRECOVERABLE. The mutex can be made
+ * consistent by calling pthread_mutex_destroy() to uninitialize the mutex, and calling
+ * pthread_mutex_int() to reinitialize the mutex.However, the state that was protected
+ * by the mutex remains inconsistent and some form of application recovery is required.
+ * ■ If the thread that acquires the lock with EOWNERDEAD terminates without unlocking the
+ * mutex, the next owner acquires the lock with an EOWNERDEAD return code.

+      * 
+      * The robustness of mutex is contained in the robustness attribute
+      * of the mutex attributes. Valid mutex robustness values are:
+      *
+      * PTHREAD_MUTEX_STALLED
+      * No special actions are taken if the owner of the mutex is
+      * terminated while holding the mutex lock. This can lead to
+      * deadlocks if no other thread can unlock the mutex.
+      * This is the default value.
+      * 
+      * PTHREAD_MUTEX_ROBUST
+      * If the process containing the owning thread of a robust mutex
+      * terminates while holding the mutex lock, the next thread that
+      * acquires the mutex shall be notified about the termination by
+      * the return value [EOWNERDEAD] from the locking function. If the
+      * owning thread of a robust mutex terminates while holding the mutex
+      * lock, the next thread that acquires the mutex may be notified
+      * about the termination by the return value [EOWNERDEAD]. The
+      * notified thread can then attempt to mark the state protected by
+      * the mutex as consistent again by a call to
+      * pthread_mutex_consistent(). After a subsequent successful call to
+      * pthread_mutex_unlock(), the mutex lock shall be released and can
+      * be used normally by other threads. If the mutex is unlocked without
+      * a call to pthread_mutex_consistent(), it shall be in a permanently
+      * unusable state and all attempts to lock the mutex shall fail with
+      * the error [ENOTRECOVERABLE]. The only permissible operation on such
+      * a mutex is pthread_mutex_destroy().

+      * The pthread_mutexattr_setrobust() and
+      * pthread_mutexattr_getrobust() functions  respectively set and
+      * get the mutex robust  attribute. This attribute is set in  the
+      * robust  parameter to these functions. The default value of the
+      * robust  attribute is  PTHREAD_MUTEX_STALLED.
+      * 
+      * The robustness of mutex is contained in the robustness attribute
+      * of the mutex attributes. Valid mutex robustness values are:
+      *
+      * PTHREAD_MUTEX_STALLED
+      * No special actions are taken if the owner of the mutex is
+      * terminated while holding the mutex lock. This can lead to
+      * deadlocks if no other thread can unlock the mutex.
+      * This is the default value.
+      * 
+      * PTHREAD_MUTEX_ROBUST
+      * If the process containing the owning thread of a robust mutex
+      * terminates while holding the mutex lock, the next thread that
+      * acquires the mutex shall be notified about the termination by
+      * the return value [EOWNERDEAD] from the locking function. If the
+      * owning thread of a robust mutex terminates while holding the mutex
+      * lock, the next thread that acquires the mutex may be notified
+      * about the termination by the return value [EOWNERDEAD]. The
+      * notified thread can then attempt to mark the state protected by
+      * the mutex as consistent again by a call to
+      * pthread_mutex_consistent(). After a subsequent successful call to
+      * pthread_mutex_unlock(), the mutex lock shall be released and can
+      * be used normally by other threads. If the mutex is unlocked without
+      * a call to pthread_mutex_consistent(), it shall be in a permanently
+      * unusable state and all attempts to lock the mutex shall fail with
+      * the error [ENOTRECOVERABLE]. The only permissible operation on such
+      * a mutex is pthread_mutex_destroy().
+      *
+      * RESULTS
+      *              0               successfully set attribute,
+      *              EINVAL          'attr' or 'robust' is invalid,
+      *

-/*
- * About MCS locks:
- *
- * MCS locks are queue-based locks, where the queue nodes are local to the
- * thread. The 'lock' is nothing more than a global pointer that points to
- * the last node in the queue, or is NULL if the queue is empty.
- * 
- * Originally designed for use as spin locks requiring no kernel resources
- * for synchronisation or blocking, the implementation below has adapted
- * the MCS spin lock for use as a general mutex that will suspend threads
- * when there is lock contention.
- *
- * Because the queue nodes are thread-local, most of the memory read/write
- * operations required to add or remove nodes from the queue do not trigger
- * cache-coherence updates.
- *
- * Like 'named' mutexes, MCS locks consume system resources transiently -
- * they are able to acquire and free resources automatically - but MCS
- * locks do not require any unique 'name' to identify the lock to all
- * threads using it.
- *
- * Usage of MCS locks:
- *
- * - you need a global ptw32_mcs_lock_t instance initialised to 0 or NULL.
- * - you need a local thread-scope ptw32_mcs_local_node_t instance, which
- *   may serve several different locks but you need at least one node for
- *   every lock held concurrently by a thread.
- *
- * E.g.:
- * 
- * ptw32_mcs_lock_t lock1 = 0;
- * ptw32_mcs_lock_t lock2 = 0;
- *
- * void *mythread(void *arg)
- * {
- *   ptw32_mcs_local_node_t node;
- *
- *   ptw32_mcs_acquire (&lock1, &node);
- *   ptw32_mcs_release (&node);
- *
- *   ptw32_mcs_acquire (&lock2, &node);
- *   ptw32_mcs_release (&node);
- *   {
- *      ptw32_mcs_local_node_t nodex;
- *
- *      ptw32_mcs_acquire (&lock1, &node);
- *      ptw32_mcs_acquire (&lock2, &nodex);
- *
- *      ptw32_mcs_release (&nodex);
- *      ptw32_mcs_release (&node);
- *   }

+/*
+ * About MCS locks:
+ *
+ * MCS locks are queue-based locks, where the queue nodes are local to the
+ * thread. The 'lock' is nothing more than a global pointer that points to
+ * the last node in the queue, or is NULL if the queue is empty.
+ * 
+ * Originally designed for use as spin locks requiring no kernel resources
+ * for synchronisation or blocking, the implementation below has adapted
+ * the MCS spin lock for use as a general mutex that will suspend threads
+ * when there is lock contention.
+ *
+ * Because the queue nodes are thread-local, most of the memory read/write
+ * operations required to add or remove nodes from the queue do not trigger
+ * cache-coherence updates.
+ *
+ * Like 'named' mutexes, MCS locks consume system resources transiently -
+ * they are able to acquire and free resources automatically - but MCS
+ * locks do not require any unique 'name' to identify the lock to all
+ * threads using it.
+ *
+ * Usage of MCS locks:
+ *
+ * - you need a global ptw32_mcs_lock_t instance initialised to 0 or NULL.
+ * - you need a local thread-scope ptw32_mcs_local_node_t instance, which
+ *   may serve several different locks but you need at least one node for
+ *   every lock held concurrently by a thread.
+ *
+ * E.g.:
+ * 
+ * ptw32_mcs_lock_t lock1 = 0;
+ * ptw32_mcs_lock_t lock2 = 0;
+ *
+ * void *mythread(void *arg)
+ * {
+ *   ptw32_mcs_local_node_t node;
+ *
+ *   ptw32_mcs_acquire (&lock1, &node);
+ *   ptw32_mcs_lock_release (&node);
+ *
+ *   ptw32_mcs_lock_acquire (&lock2, &node);
+ *   ptw32_mcs_lock_release (&node);
+ *   {
+ *      ptw32_mcs_local_node_t nodex;
+ *
+ *      ptw32_mcs_lock_acquire (&lock1, &node);
+ *      ptw32_mcs_lock_acquire (&lock2, &nodex);
+ *
+ *      ptw32_mcs_lock_release (&nodex);
+ *      ptw32_mcs_lock_release (&node);
+ *   }

-      *      This function waits on a POSIX semaphore. If the
-      *      semaphore value is greater than zero, it decreases
-      *      its value by one. If the semaphore value is zero, then
-      *      the calling thread (or process) is blocked until it can
-      *      successfully decrease the value.
-      *
-      *      Unlike sem_wait(), this routine is non-cancelable.
-      *
-      * RESULTS

+      * ------------------------------------------------------
+      * DESCRIPTION
+      *      This function waits on a POSIX semaphore. If the
+      *      semaphore value is greater than zero, it decreases
+      *      its value by one. If the semaphore value is zero, then
+      *      the calling thread (or process) is blocked until it can
+      *      successfully decrease the value.
+      *
+      *      Unlike sem_wait(), this routine is non-cancelable.
+      *
+      * RESULTS
+      *              0               successfully decreased semaphore,
+      *              -1              failed, error in errno.
+      * ERRNO
+      *              EINVAL          'sem' is not a valid semaphore,
+      *              ENOSYS          semaphores are not supported,
+      *              EINTR           the function was interrupted by a signal,

-
-	* Makefile (STATICRESULTS): Add all tests into suite for static
-	library.
-	* GNUmakefile (STATICTESTS): Likewise, except for openmp1.c which
-	has a DLL dependency.
-
-2010-02-04  Ross Johnson 
-
-	* openmp1.c: New; for libgomp compatibility (OpenMP).
-	* barrier5.c: Rewrite after changes to barriers.
-	* barrier6.c: New.
-	* benchtest6.c: New; timing barriers.
-	* GNUMakefile: Update for new tests.
-	* Makefile: Ditto.
-	* BMakefile: Ditto.
-	* once3.c: Improve cancelation testing.
-	* stress1.c: Fix comment.
-
-2007-01-04  Ross Johnson 
-
-        * context1.c: Include context.h from library sources and remove
-        x86 dependence in main().
-
-2005-06-12  Ross Johnson  
-
-	* stress1.c (millisecondsFromNow): Remove limit 0 <= millisecs < 1000;
-	now works for -INT_MAX <= millisecs <= INT_MAX; not needed for

-	* semaphore4.c: New test.
-	* semaphore4t.c: New test.
-	* Debug.dsp (et al): Created MSVC Workspace project to aid debugging.
-	* All: Many tests have been modified to work with the new pthread
-	ID type; some other corrections were made after some library
-	functions were semantically strengthened. For example,
-	pthread_cond_destroy() no longer destroys a busy CV, which
-	required minor redesigns of some tests, including some where
-	the mutex associated with the CV was not locked during
-	signaling and broadcasting.
-
-2004-10-23  Ross Johnson  
-
-	* condvar3.c: Fixed mutex operations that were incorrectly
-	placed in relation to their condition variable operations.

-	destroy the cv queueing sempahore.

-
-	* benchtest.h: Move old mutex code into benchlib.c.
-	* benchlib.c: New statically linked module to ensure that

-2002-02-28  Ross Johnson  
-
-	* exception3.c (terminateFunction): For MSVC++, call
-	exit() rather than pthread_exit(). Add comments to explain
-	why.
-	   * Notes from the MSVC++ manual:
-	   *       1) A term_func() should call exit(), otherwise
-	   *          abort() will be called on return to the caller.
-	   *          abort() raises SIGABRT. The default signal handler
-	   *          for all signals terminates the calling program with
-	   *          exit code 3.
-	   *       2) A term_func() must not throw an exception. Therefore
-	   *          term_func() should not call pthread_exit() if an
-	   *          an exception-using version of pthreads-win32 library
-	   *          is being used (i.e. either pthreadVCE or pthreadVSE).

+2011-05-05  Ross Johnson 
+
+	* openmp1.c: Add missing test; used to comfirm that this

+	now works for -INT_MAX <= millisecs <= INT_MAX; not needed for
+	stress1.c but should be general anyway.
+
+2005-05-18  Ross Johnson  
+
+	* reuse2.c (main): Must use a read with memory barrier semantics
+	when polling 'done' to force the cache into coherence on MP systems.

+2005-05-15  Ross Johnson  
+
+	* detach1.c: New test.
+	* join1.c: Reduce sleep times.

+	* join3.c: Likewise.
+
+2005-04-18  Ross Johnson  
+
+	* condvar3.c: Remove locks from around signalling calls - should not

+
+	* semaphore4.c: New test.
+	* semaphore4t.c: New test.
+	* Debug.dsp (et al): Created MSVC Workspace project to aid debugging.
+	* All: Many tests have been modified to work with the new pthread
+	ID type; some other corrections were made after some library
+	functions were semantically strengthened. For example,
+	pthread_cond_destroy() no longer destroys a busy CV, which
+	required minor redesigns of some tests, including some where
+	the mutex associated with the CV was not locked during
+	signaling and broadcasting.
+
+2004-10-23  Ross Johnson  
+
+	* condvar3.c: Fixed mutex operations that were incorrectly
+	placed in relation to their condition variable operations.
+	The error became evident after sem_destroy() was rewritten
+	and conditions for destroing the semaphore were tightened.
+	As a result, pthread_cond_destroy() was not able to
+	destroy the cv queueing sempahore.
+	* condvar3_1.c: Likewise.

+
+2004-09-08  Alexandre Girao

+	priority.
+
+2004-05-16  Ross Johnson  
+
+	* cancel9.c: New test.
+	* cancel3.c: Remove inappropriate conditional compilation;
+	GNU C version of test suite no longer quietly skips this test.
+	* cancel5.c: Likewise.
+	* GNUmakefile: Can now build individual test app using default
+	C version of library using 'make clean testname.c'.
+	* Makefile: Likewise for VC using 'nmake clean test testname.c'.
+
+2003-10-14  Ross Johnson  
+
+	* Wmakefile: New makefile for Watcom testing.
+
+2003-09-18  Ross Johnson  
+
+	* benchtest.h: Move old mutex code into benchlib.c.
+	* benchlib.c: New statically linked module to ensure that
+	bench apps don't inline the code and therefore have an unfair
+	advantage over the pthreads lib routines. Made little or no
+	difference.
+	* benchtest1.c: Minor change to avoid compiler warnings.
+	* benchtest5.c: Likewise.
+	* benchtest2.c: Fix misinformation in output report.
+	* README.BENCH: Add comments on results.

+ 	* create2.c: Now included in test regime.
+
+2003-07-19  Ross Johnson  
+
+	* eyal1.c (waste_time): Make threads do more work to ensure that
+	all threads get to do some work.
+	* semaphore1.c: Make it clear that certain errors are expected.
+	* exception2.c (non_MSVC code sections): Change to include
+	C++ standard include file, i.e. change  to .
+	* exception3.c (non_MSVC code sections): Likewise; qualify std::
+	namespace entities where necessary.
+	* GNUmakefile: modified to work in the MsysDTK (newer MinGW)
+	environment; define CC as gcc or g++ as appropriate because
+	using gcc -x c++ doesn't link with required c++ libs by default,
+	but g++ does.
+
+2002-12-11  Ross Johnson  
+
+	* mutex7e.c: Assert EBUSY return instead of EDEADLK.

+
+	* semaphore1.c: New test.
+
+	* Makefile: Add rule to generate pre-processor output.
+
+2002-02-28  Ross Johnson  
+
+	* exception3.c (terminateFunction): For MSVC++, call
+	exit() rather than pthread_exit(). Add comments to explain
+	why.
+	   * Notes from the MSVC++ manual:
+	   *       1) A term_func() should call exit(), otherwise
+	   *          abort() will be called on return to the caller.
+	   *          abort() raises SIGABRT. The default signal handler
+	   *          for all signals terminates the calling program with
+	   *          exit code 3.
+	   *       2) A term_func() must not throw an exception. Therefore
+	   *          term_func() should not call pthread_exit() if an
+	   *          an exception-using version of pthreads-win32 library
+	   *          is being used (i.e. either pthreadVCE or pthreadVSE).

+ * Test Synopsis:
+ * - Stress test condition variables, mutexes, semaphores.
+ *
+ * Test Method (Validation or Falsification):
+ * - Validation
+ *
+ * Requirements Tested:
+ * - Correct accounting of semaphore and condition variable waiters.
+ *
+ * Features Tested:
+ * - 
+ *
+ * Cases Tested:
+ * - 
+ *
+ * Description:
+ * Attempting to expose race conditions in cond vars, semaphores etc.
+ * - Master attempts to signal slave close to when timeout is due.
+ * - Master and slave do battle continuously until main tells them to stop.
+ * - Afterwards, the CV must be successfully destroyed (will return an
+ * error if there are waiters (including any internal semaphore waiters,
+ * which, if there are, cannot be real waiters).
+ *
+ * Environment:
+ * - 
+ *
+ * Input:
+ * - None.
+ *
+ * Output:
+ * - File name, Line number, and failed expression on failure.
+ * - No output on success.
+ *
+ * Assumptions:
+ * - 
+ *
+ * Pass Criteria:
+ * - CV is successfully destroyed.
+ *
+ * Fail Criteria:
+ * - CV destroy fails.
