+
+
+We are pleased to announce the availability of a new release of
+Pthreads-win32, an Open Source Software implementation of the
+Threads component of the POSIX 1003.1 2001 Standard for Microsoft's
+Win32 environment. Some functions from other sections of POSIX
+1003.1 2001 are also supported including semaphores and scheduling
+functions.
+
+Some common non-portable functions are also implemented for
+additional compatibility, as are a few functions specific
+to pthreads-win32 for easier integration with Win32 applications.
+
+Pthreads-win32 is free software, distributed under the GNU Lesser
+General Public License (LGPL).
+
+
+Acknowledgements
+----------------
+This library is based originally on a Win32 pthreads
+implementation contributed by John Bossom <John.Bossom@cognos.com>.
+
+The implementation of Condition Variables uses algorithms developed
+by Alexander Terekhov and Louis Thomas.
+
+The implementation of POSIX mutexes has been improved by Thomas Pfaff
+and later by Alexander Terekhov.
+
+The implementation of Spinlocks and Barriers was contributed
+by Ross Johnson.
+
+The implementation of read/write locks was contributed by
+Aurelio Medina and improved by Alexander Terekhov.
+
+Many others have contributed significant time and effort to solve crutial
+problems in order to make the library workable, robust and reliable.
+
+Thanks to Xavier Leroy for granting permission to use and modify his
+LinuxThreads manual pages.
+
+Thanks to The Open Group for making the Single Unix Specification
+publicly available - many of the manual pages included in the package
+were extracted from it.
+
+There is also a separate CONTRIBUTORS file. This file and others are
+on the web site:

+Application Development Environments
+------------------------------------
+
+See the README file for more information.
+
+MSVC:
+MSVC using SEH works. Distribute pthreadVSE.dll with your application.
+MSVC using C++ EH works. Distribute pthreadVCE.dll with your application.
+MSVC using C setjmp/longjmp works. Distribute pthreadVC.dll with your application.
+
+
+Mingw32:
+See the FAQ, Questions 6 and 10.
+
+Mingw using C++ EH works. Distribute pthreadGCE.dll with your application.
+Mingw using C setjmp/longjmp works. Distribute pthreadGC.dll with your application.
+
+
+Cygwin: (http://sourceware.cygnus.com/cygwin/)
+Developers using Cygwin will not need pthreads-win32 since it has POSIX threads
+support. Refer to its documentation for details and extent.
+
+
+UWIN:
+UWIN is a complete Unix-like environment for Windows from AT&T. Pthreads-win32
+doesn't currently support UWIN (and vice versa), but that may change in the
+future.
+
+Generally:
+For convenience, the following pre-built files are available on the FTP site
+(see Availability above):
+
+ pthread.h - for POSIX 1c threads
+ semaphore.h - for POSIX 1b semaphores
+ sched.h - for POSIX 1b scheduling
+ pthreadVCE.dll - built with MSVC++ compiler using C++ EH
+ pthreadVCE.lib
+ pthreadVC.dll - built with MSVC compiler using C setjmp/longjmp
+ pthreadVC.lib
+ pthreadVSE.dll - built with MSVC compiler using SEH
+ pthreadVSE.lib
+ pthreadGCE.dll - built with Mingw32 G++ 2.95.2-1
+ pthreadGC.dll - built with Mingw32 GCC 2.95.2-1 using setjmp/longjmp
+ libpthreadGCE.a - derived from pthreadGCE.dll
+ libpthreadGC.a - derived from pthreadGC.dll
+ gcc.dll - needed if distributing applications that use
+ pthreadGCE.dll (but see the FAQ Q 10 for the latest
+ related information)
+
+These are the only files you need in order to build POSIX threads
+applications for Win32 using either MSVC or Mingw32.
+
+See the FAQ file in the source tree for additional information.

The form - of pthread_once is as proposed by Alexander Terekhov (see entry of - 2005-03-13). The MCS lock implementation does not require a unique - 'name' to identify the lock between threads.

The effect of this is to save one handle per association, - which could potentially equal the number of keys multiplied by the - number of threads, accumulating over time - and to free the - association memory as soon as it is no longer referenced by either - the key or the thread. Previously, the handle and memory were - released only after BOTH key and thread no longer referenced the - association.

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. 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) { - <init> - 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. An uncontested - Win32 mutex lock operation can be 50 (or more) times slower than an - uncontested EnterCS operation. - - Ultimately, the named mutex trick is making use of the global locks maintained - by the kernel. - - * pthread.h (pthread_once_t_): One flag and an event HANDLE added. - (PTHREAD_ONCE_INIT): Additional values included. - -2005-03-08 Ross Johnson <rpj at callisto.canberra.edu.au> - - * pthread_once.c (pthread_once): Redesigned to elliminate potential - starvation problem. - - reported by Gottlob Frege <gottlobfrege at gmail.com> - - * ptw32_threadDestroy.c (ptw32_threadDestroy): Implicit threads were - not closing their Win32 thread duplicate handle. - - reported by Dmitrii Semii <bogolt at gmail.com> - -2005-01-25 Ralf Kubis <RKubis at mc.com> - - * Attempted acquisition of recursive mutex was causing waiting - threads to not be woken when the mutex is released. - - * GNUmakefile (GCE): Generate correct version resource comments. - -2005-01-01 Konstantin Voronkov <beowinkle at yahoo.com> - - * pthread_mutex_lock.c (pthread_mutex_lock): The new atomic exchange - mutex algorithm is known to allow a thread to steal the lock off - FIFO waiting threads. The next waiting FIFO thread gets a spurious - wake-up and must attempt to re-acquire the lock.

This was obviated - by user space sema acquisition in sem_wait() and sem_timedwait(), - which are also cancelation points. A call to pthread_testcancel() - was required, which introduced a kernel call, effectively nullifying - any gains made by the user space sem acquisition checks. - * pthread_cancel.c (pthread_cancel): Set new thread - 'PThreadStateCancelPending' state. - -2004-10-29 Ross Johnson <rpj at callisto.canberra.edu.au> - - * implement.h (pthread_t): Renamed to ptw32_thread_t; struct contains - all thread state. - * pthread.h (ptw32_handle_t): New general purpose struct to serve - as a handle for various reusable object IDs - currently only used - by pthread_t; contains a pointer to ptw32_thread_t (thread state) - and a general purpose uint for use as a reuse counter or flags etc. - (pthread_t): typedef'ed to ptw32_handle_t; the uint is the reuse - counter that allows the library to maintain unique POSIX thread IDs. - When the pthread struct reuse stack was introduced, threads would - often acquire an identical ID to a previously destroyed thread.

Win32 semaphores are - used instead of events in order to support efficient multiple posting. - If the whole modify/release isn't atomic, a race between - sem_timedwait() and sem_post() could result in a release when there is - no waiting semaphore, which would cause too many threads to proceed. - * sem_wait.c (sem_wait): Use new 'lock'element. - * sem_timedwait.c (sem_timedwait): Likewise. - * sem_trywait.c (sem_trywait): Likewise. - * sem_post.c (sem_post): Likewise. - * sem_post_multiple.c (sem_post_multiple): Likewise. - * sem_getvalue.c (sem_getvalue): Likewise. - * ptw32_semwait.c (ptw32_semwait): Likewise. - * sem_destroy.c (sem_destroy): Likewise; also tightened the conditions - for semaphore destruction; in particular, a semaphore will not be - destroyed if it has waiters. - * sem_timedwait.c (sem_timedwait): Added cancel cleanup handler to - restore sema value when cancelled. - * sem_wait.c (sem_wait): Likewise. - -2004-10-21 Ross Johnson <rpj at callisto.canberra.edu.au> - - * pthread_mutex_unlock.c (pthread_mutex_unlock): Must use PulseEvent() - rather than SetEvent() to reset the event if there are no waiters. - -2004-10-19 Ross Johnson <rpj at callisto.canberra.edu.au> - - * sem_init.c (sem_init): New semaphore model based on the same idea - as mutexes, i.e. user space interlocked check to avoid - unnecessarily entering kernel space. Wraps the Win32 semaphore and - keeps it's own counter. Although the motivation to do this has existed - for a long time, credit goes to Alexander Terekhov for providing - the logic. 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. The GCE version works fine, so it is presumed to - be a bug in MSVC++ 6.0. The cancelation exception is thrown and caught - correctly, but the cleanup class destructor is never called.

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 <rpj at callisto.canberra.edu.au> - - * 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.

The call will succeed - in unlocking the mutex if it is currently locked, but a - subsequent unlock by the true owner will then fail with EPERM. - This is however consistent with some other implementations. - (pthread_mutex_unlock): Likewise. - (pthread_mutex_trylock): Likewise. - (pthread_mutex_destroy): Likewise. - * attr.c (pthread_attr_init): PTHREAD_EXPLICIT_SCHED is the - default inheritance attribute;

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. On Win9x, and early - versions of NT 'forcecs' will need to be set in order to get - critical section based mutexes. - -Sun Jan 17 12:01:26 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au> - - * pthread.h (PTHREAD_MUTEX_INITIALIZER): Init new 'staticinit' - value to '1' and existing 'valid' value to '1'. - - * global.c (ptw32_mutex_test_init_lock): Add. - - * implement.h (ptw32_mutex_test_init_lock.): Add extern. - - * private.c (ptw32_processInitialize): Init critical section for - global lock used by _mutex_check_need_init(). - (ptw32_processTerminate): Ditto (:s/Init/Destroy/). - - * dll.c (dllMain): Move call to FreeLibrary() so that it is only - called once when the process detaches. - - * mutex.c (_mutex_check_need_init): New static function to test - and init PTHREAD_MUTEX_INITIALIZER mutexes. 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 <rpj at ixobrychus.canberra.edu.au> - - * 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 <rpj at ixobrychus.canberra.edu.au> - - * condvar.c (cond_timedwait): Remove comment. - -Fri Jan 15 15:41:28 1999 Ross Johnson <rpj at swan.canberra.edu.au> - - * 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 <rpj at swan.canberra.edu.au> - - * 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 <rpj at ixobrychus.canberra.edu.au> - - * build.bat: Delete old binaries before compiling/linking. - -Tue Jan 12 09:58:38 1999 Tor Lillqvist <tml at iki.fi> - - * dll.c: The Microsoft compiler pragmas probably are more - appropriately protected by _MSC_VER than by _WIN32. - - * pthread.h: Define ETIMEDOUT.

+
+ * pthread_once.c: Re-implement using an MCS queue-based lock. The form
+ of pthread_once is as proposed by Alexander Terekhov (see entry of
+ 2005-03-13). The MCS lock implementation does not require a unique
+ 'name' to identify the lock between threads. Attempts to get the Event
+ or Semaphore based versions of pthread_once to a satisfactory level
+ of robustness have thus far failed. The last problem (avoiding races
+ involving non recycle-unique Win32 HANDLEs) was giving everyone
+ grey hair trying to solve it.
+
+ * ptw32_MCS_lock.c: New MCS queue-based lock implementation. These
+ locks are efficient: they have very low overhead in the uncontended case;
+ are efficient in contention and minimise cache-coherence updates in
+ managing the user level FIFO queue; do not require an ABI change in the
+ library.
+
+2005-05-27 Alexander Gottwald <alexander.gottwald at s1999.tu-chemnitz.de>
+
+ * pthread.h: Some things, like HANDLE, were only defined if
+ PTW32_LEVEL was >= 3. They should always be defined.
+
+2005-05-25 Vladimir Kliatchko <vladimir at kliatchko.com>
+
+ * pthread_once.c: Eliminate all priority operations and other
+ complexity by replacing the event with a semaphore. The advantage
+ of the change is the ability to release just one waiter if the

+ * GNUmakefile: Patched to allow cross-compile with mingw32 on Linux.
+ It uses macros instead of referencing dlltool, gcc and g++ directly;

+ * pthread_win32_attach_detach_np.c (pthread_win32_thread_detach_np):
+ Move on-exit-only stuff from ptw32_threadDestroy() to here.
+ * ptw32_threadDestroy.c: It's purpose is now only to reclaim thread
+ resources for detached threads, or via pthread_join() or
+ pthread_detach() on joinable threads.
+ * ptw32_threadStart.c: Calling user destruct routines has moved to
+ pthread_win32_thread_detach_np(); call pthread_win32_thread_detach_np()
+ directly if statically linking, otherwise do so via dllMain; store
+ thread return value in thread struct for all cases, including

+ pthread_win32_thread_detach_np.
+ * pthread_join.c (pthread_join): Don't try to get return code from
+ Win32 thread - always get it from he thread struct.
+ * pthread_detach.c (pthread_detach): reduce extent of the thread

+ change all references to it.
+ * implement.h (struct ThreadKeyAssoc): Remove lock; add prevKey
+ and prevThread pointers; re-implemented all routines that use this
+ struct. The effect of this is to save one handle per association,
+ which could potentially equal the number of keys multiplied by the
+ number of threads, accumulating over time - and to free the
+ association memory as soon as it is no longer referenced by either
+ the key or the thread. Previously, the handle and memory were
+ released only after BOTH key and thread no longer referenced the
+ association. That is, often no association resources were released
+ until the process itself exited. In addition, at least one race
+ condition has been removed - where two threads could attempt to
+ release the association resources simultaneously - one via
+ ptw32_callUserDestroyRoutines and the other via
+ pthread_key_delete.

+
+ * pthread_once.c (pthread_once): Downgrade interlocked operations to simple
+ memory operations where these are protected by the critical section; edit
+ comments.
+
+2005-03-13 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_once.c (pthread_once): Completely redesigned; a change was
+ required to the ABI (pthread_once_t_), and resulting in a version
+ compatibility index increment.
+
+ NOTES:
+ The design (based on pseudo code contributed by Gottlob Frege) avoids
+ creating a kernel object if there is no contention. 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. 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) {
+ <init>
+ 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. An uncontested
+ Win32 mutex lock operation can be 50 (or more) times slower than an
+ uncontested EnterCS operation.
+
+ Ultimately, the named mutex trick is making use of the global locks maintained
+ by the kernel.
+
+ * pthread.h (pthread_once_t_): One flag and an event HANDLE added.
+ (PTHREAD_ONCE_INIT): Additional values included.

+ * pthread_mutex_lock.c (pthread_mutex_lock): The new atomic exchange
+ mutex algorithm is known to allow a thread to steal the lock off

+ was setting itself as the mutex's owner before the re-acquisition.

+
+2004-11-19 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * config.h (PTW32_THREAD_ID_REUSE_INCREMENT): Added to allow
+ building the library for either unique thread IDs like Solaris
+ or non-unique thread IDs like Linux; allows application developers
+ to override the library's default insensitivity to some apps
+ that may not be strictly POSIX compliant.
+ * version.rc: New resource module to encode version information
+ within the DLL.
+ * pthread.h: Added PTW32_VERSION* defines and grouped sections
+ required by resource compiler together; bulk of file is skipped
+ if RC_INVOKED. Defined some error numbers and other names for
+ Borland compiler.
+
+2004-11-02 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_cond_wait.c (ptw32_cond_wait_cleanup): Lock CV mutex at

+ (ptw32_threadReuseBottom): New global variable.
+ * global.c (ptw32_threadReuseBottom): Declare new variable.

+ PTW32_THREAD_REUSE_EMPTY.
+

+
+ * implement.h (PThreadState): Add new state value
+ 'PThreadStateCancelPending'.
+ * pthread_testcancel.c (pthread_testcancel): Use new thread
+ 'PThreadStateCancelPending' state as short cut to avoid entering
+ kernel space via WaitForSingleObject() call. This was obviated
+ by user space sema acquisition in sem_wait() and sem_timedwait(),
+ which are also cancelation points. A call to pthread_testcancel()
+ was required, which introduced a kernel call, effectively nullifying
+ any gains made by the user space sem acquisition checks.
+ * pthread_cancel.c (pthread_cancel): Set new thread
+ 'PThreadStateCancelPending' state.
+
+2004-10-29 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * implement.h (pthread_t): Renamed to ptw32_thread_t; struct contains
+ all thread state.
+ * pthread.h (ptw32_handle_t): New general purpose struct to serve
+ as a handle for various reusable object IDs - currently only used
+ by pthread_t; contains a pointer to ptw32_thread_t (thread state)
+ and a general purpose uint for use as a reuse counter or flags etc.
+ (pthread_t): typedef'ed to ptw32_handle_t; the uint is the reuse
+ counter that allows the library to maintain unique POSIX thread IDs.
+ When the pthread struct reuse stack was introduced, threads would
+ often acquire an identical ID to a previously destroyed thread. The
+ same was true for the pre-reuse stack library, by virtue of pthread_t
+ being the address of the thread struct. The new pthread_t retains
+ the reuse stack but provides virtually unique thread IDs.
+ * sem_wait.c (ptw32_sem_wait_cleanup): New routine used for
+ cancelation cleanup.
+ * sem_timedwait.c (ptw32_sem_timedwait_cleanup): Likewise.
+
+2004-10-22 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * sem_init.c (sem_init): Introduce a 'lock' element in order to
+ replace the interlocked operations with conventional serialisation.
+ This is needed in order to be able to atomically modify the sema
+ value and perform Win32 sema release operations. Win32 semaphores are
+ used instead of events in order to support efficient multiple posting.
+ If the whole modify/release isn't atomic, a race between
+ sem_timedwait() and sem_post() could result in a release when there is
+ no waiting semaphore, which would cause too many threads to proceed.
+ * sem_wait.c (sem_wait): Use new 'lock'element.
+ * sem_timedwait.c (sem_timedwait): Likewise.
+ * sem_trywait.c (sem_trywait): Likewise.

+ * sem_getvalue.c (sem_getvalue): Likewise.
+ * ptw32_semwait.c (ptw32_semwait): Likewise.
+ * sem_destroy.c (sem_destroy): Likewise; also tightened the conditions
+ for semaphore destruction; in particular, a semaphore will not be
+ destroyed if it has waiters.
+ * sem_timedwait.c (sem_timedwait): Added cancel cleanup handler to
+ restore sema value when cancelled.
+ * sem_wait.c (sem_wait): Likewise.
+
+2004-10-21 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_mutex_unlock.c (pthread_mutex_unlock): Must use PulseEvent()
+ rather than SetEvent() to reset the event if there are no waiters.
+
+2004-10-19 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * sem_init.c (sem_init): New semaphore model based on the same idea
+ as mutexes, i.e. user space interlocked check to avoid
+ unnecessarily entering kernel space. Wraps the Win32 semaphore and
+ keeps it's own counter. Although the motivation to do this has existed
+ for a long time, credit goes to Alexander Terekhov for providing
+ the logic. 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. The GCE version works fine, so it is presumed to
+ be a bug in MSVC++ 6.0. The cancelation exception is thrown and caught
+ correctly, but the cleanup class destructor is never called. The failing
+ test is tests\semaphore4.c.
+ * sem_wait.c (sem_wait): Implemented user space check model.

+
+ * pthread_mutex_lock.c (pthread_mutex_lock): New algorithm using
+ Terekhov's xchg based variation of Drepper's cmpxchg model.
+ Theoretically, xchg uses fewer clock cycles than cmpxchg (using IA-32
+ as a reference), however, in my opinion bus locking dominates the
+ equation on smp systems, so the model with the least number of bus
+ lock operations in the execution path should win, which is Terekhov's
+ variant. 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).

+2004-09-27 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_mutex_lock.c (pthread_mutex_lock): Separate
+ PTHREAD_MUTEX_NORMAL logic since we do not need to keep or check some
+ state required by other mutex types; do not check mutex pointer arg
+ for validity - leave this to the system since we are only checking
+ for NULL pointers. This should improve speed of NORMAL mutexes and
+ marginally improve speed of other type.
+ * pthread_mutex_trylock.c (pthread_mutex_trylock): Likewise.
+ * pthread_mutex_unlock.c (pthread_mutex_unlock): Likewise; also avoid
+ entering the critical section for the no-waiters case, with approx.
+ 30% reduction in lock/unlock overhead for this case.
+ * pthread_mutex_timedlock.c (pthread_mutex_timedlock): Likewise; also
+ no longer keeps mutex if post-timeout second attempt succeeds - this
+ will assist applications that wish to impose strict lock deadlines,
+ rather than simply to escape from frozen locks.

+
+ * create.c (pthread_create): Don't create a thread if the thread

+ 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.

+ (ptw32_RegisterCancelation): Drop in replacement for QueueUserAPCEx()
+ if it can't be used. Provides older style non-preemptive async
+ cancelation.
+ * pthread_win32_attach_detach_np.c (pthread_win32_attach_np):
+ Auto-detect quserex.dll and the availability of alertdrv.sys;
+ initialise and close on process attach/detach.
+ * global.c (ptw32_register_cancelation): Pointer to either

+2003-10-20 James Ewing <james.ewing at sveasoft.com>
+
+ * ptw32_getprocessors.c: Some Win32 environments don't have

+
+2003-10-15 Ross Johnson <ross at callisto.canberra.edu.au>

+ editor ugliness (used GNU indent utility in default style).
+
+2003-10-15 Alex Blanco <Alex.Blanco at motorola.com>
+
+ * sem_init.c (sem_init): Would call CreateSemaphore even if the sema
+ struct calloc failed; was not freeing calloced memory if either
+ CreateSemaphore or CreateEvent failed.
+
+2003-10-14 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * pthread.h: Add Watcom compiler compatibility. 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 <rpj at callisto.canberra.edu.au>
+
+ * 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 <rpj at callisto.canberra.edu.au>
+
+ * sched_get_priority_min.c (sched_get_priority_min): On error should return -1

+ * sched_get_priority_max.c (sched_get_priority_max): Likewise.
+
+2003-09-03 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * w32_cancelableWait.c (ptw32_cancelable_wait): Allow cancelation
+ of implicit POSIX threads as well.
+
+2003-09-02 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * 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 <rpj at callisto.canberra.edu.au>
+
+ * 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 <rpj at ise.canberra.edu.au>
+
+ * 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 <rpj at ise.canberra.edu.au>
+
+ * 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 <exception> rather
+ than old-style <new.h>; 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 <pietvb at newbridges.nl>
+
+ * pthread_spin_destroy.c (pthread_spin_destroy): Was not freeing the
+ spinlock struct.
+
+2003-06-22 Nicolas Barry <boozai at yahoo.com>
+
+ * 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 <Steven.Reddie at ca.com>
+
+ * 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 <vcotirlea at hotmail.com>
+
+ * pthread.dsp: Change /MT compile flag to /MD.
+
+2003-03-04 Alexander Terekhov <TEREKHOV at de.ibm.com>
+
+ * 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 <strycek at posam.sk>
+
+2002-12-17 Thomas Pfaff <tpfaff at gmx.net>
+
+ * 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 <tpfaff at gmx.net>
+
+ * 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 <michaelj at maine.rr.com>
+
+ * 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 <rpj at special.ise.canberra.edu.au>
+
+ * 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 <TEREKHOV at de.ibm.com>
+
+ * 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 <rpj at ise.canberra.edu.au>
+
+ * 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 <rpj at special.ise.canberra.edu.au>
+
+ * 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 <rfanner at stonethree.com>
+
+ * 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 <rpj at ise.canberra.edu.au>
+
+ * 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 <rfanner at stonethree.com>
+
+ * 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 <rpj at setup1.ise.canberra.edu.au>
+
+ * 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. This change currently has nil effect.
+
+ * GNUmakefile: Correct some recent changes.
+
+ * Makefile: Add rule to generate pre-processor output.
+
+2002-02-23 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+

+
+ * pthread_cond_destroy.c: Expand the time change

+ * pthread.h: Use dllexport/dllimport attributes on functions
+ to avoid using pthread.def.
+ * sched.h: Likewise.

+
+2002-02-20 Ross Johnson <rpj at setup1.ise.canberra.edu.au>

+
+2002-02-17 Ross Johnson <rpj at setup1.ise.canberra.edu.au
+
+ * Testsuite passed.
+
+ * pthread_timechange_handler_np.c: New; following
+ a suggestion from Alexander Terekhov that CVs should
+ be broadcast so that they all re-evaluate their
+ condition variables and reset a new timeout if
+ required, whenever an application receives a
+ WM_TIMECHANGE message. This message indicates that
+ the system time has been changed. Therefore, CVs
+ waiting for a timeout set as an abs_time will possibly
+ not wake up at the expected time. Some applications
+ may not be tolerant of this.
+ * pthread_cond_init.c: Add CV to linked list.
+ * pthread_cond_destroy.c: Remove CV from linked list.
+ * global.c (ptw32_cond_list_head): New variable.

+ Reduced name space pollution.
+ -----------------------------
+ When the appropriate symbols are defined, the headers

+
+ * cancel.c: Rearranged some code and introduced checks
+ to disable cancelation at the start of a thread's cancelation
+ run to prevent double cancelation. The main problem
+ arises if a thread is canceling and then receives a subsequent
+ async cancel request.
+ * private.c: Likewise.
+ * condvar.c: Place pragmas around cleanup_push/pop to turn
+ off inline optimisation (/Obn where n>0 - MSVC only). Various

+
+2002-01-27 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * mutex.c (pthread_mutex_timedlock): New function suggested by
+ Alexander Terekhov. The logic required to implement this
+ properly came from Alexander, with some collaboration
+ with Thomas Pfaff.
+ (pthread_mutex_unlock): Wrap the waiters check and sema
+ post in a critical section to prevent a race with
+ pthread_mutex_timedlock.
+ (ptw32_timed_semwait): New function;
+ returns a special result if the absolute timeout parameter
+ represents a time already passed when called; used by
+ pthread_mutex_timedwait(). Have deliberately not reused
+ the name "ptw32_sem_timedwait" because they are not the same
+ routine.
+ * condvar.c (ptw32_cond_timedwait): Use the new sem_timedwait()
+ instead of ptw32_sem_timedwait(), which now has a different
+ function. See previous.
+ * implement.h: Remove prototype for ptw32_sem_timedwait.
+ See next.
+ (pthread_mutex_t_): Add critical section element for access
+ to lock_idx during mutex post-timeout processing.
+ * semaphore.h (sem_timedwait): See next.
+ * semaphore.c (sem_timedwait): See next.
+ * private.c (ptw32_sem_timedwait): Move to semaphore.c

+
+2002-01-15 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h: Unless the build explicitly defines __CLEANUP_SEH,
+ __CLEANUP_CXX, or __CLEANUP_C, then the build defaults to
+ __CLEANUP_C style cleanup. This style uses setjmp/longjmp
+ in the cancelation and thread exit implementations and therefore
+ won't do stack unwinding if linked to applications that have it
+ (e.g. C++ apps). This is currently consistent with most/all
+ commercial Unix POSIX threads implementations.
+
+ * spin.c (pthread_spin_init): Edit renamed function call.
+ * nonportable.c (pthread_num_processors_np): New.
+ (pthread_getprocessors_np): Renamed to ptw32_getprocessors
+ and moved to private.c.

+
+2002-01-08 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * mutex.c (pthread_mutex_trylock): use
+ ptw32_interlocked_compare_exchange function pointer
+ rather than ptw32_InterlockedCompareExchange() directly
+ to retain portability to non-iX86 processors,
+ e.g. WinCE etc. The pointer will point to the native

+2002-01-07 Thomas Pfaff <tpfaff at gmx.net>, Alexander Terekhov <TEREKHOV at de.ibm.com>
+
+ * mutex.c (pthread_mutex_init): Remove critical

+ (pthread_mutex_destroy): Likewise.
+ (pthread_mutex_unlock): Likewise.

+ recursive mutexes now increment the lock count rather
+ than return EBUSY; errorcheck mutexes return EDEADLCK

+
+
+2002-01-04 Ross Johnson <rpj at setup1.ise.canberra.edu.au>

+ * implement.h (pthread_attr_t_): Add new scope element.
+ * ANNOUNCE: Fix out of date comment next to

+
+2001-12-21 Alexander Terekhov <TEREKHOV at de.ibm.com>

+ (pthread_mutex_trylock): Likewise.
+
+2001-10-26 prionx@juno.com
+
+ * semaphore.c (sem_init): Fix typo and missing bracket
+ in conditionally compiled code. Only older versions of
+ WinCE require this code, hence it doesn't normally get
+ tested; somehow when sem_t reverted to an opaque struct
+ the calloc NULL check was left in the conditionally included
+ section.
+ (sem_destroy): Likewise, the calloced sem_t wasn't being freed.
+
+2001-10-25 Ross Johnson <rpj at setup1.ise.canberra.edu.au>

+
+2001-10-24 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * attr.c (pthread_attr_setstacksize): Quell warning
+ from LCC by conditionally compiling the stacksize

+ (stacksize < PTHREAD_STACK_MIN) is suspicious
+ because STACK_MIN is 0 and stacksize is of type
+ size_t (or unsigned int).
+
+2001-10-17 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * barrier.c: Move _LONG and _LPLONG defines into

+ * spin.c: Likewise; ptw32_interlocked_compare_exchange used
+ in place of InterlockedCompareExchange directly.
+ * global.c (ptw32_interlocked_compare_exchange): Add
+ prototype for this new routine pointer to be used when
+ InterlockedCompareExchange isn't supported by Windows.
+ * nonportable.c (pthread_win32_process_attach_np): Check for
+ support of InterlockedCompareExchange in kernel32 and assign its
+ address to ptw32_interlocked_compare_exchange if it exists, or
+ our own ix86 specific implementation ptw32_InterlockedCompareExchange.
+ *private.c (ptw32_InterlockedCompareExchange): An
+ implementation of InterlockedCompareExchange() which is
+ specific to ix86; written directly in assembler for either

+ InterlockedCompareExchange().
+
+ * sched.c (sched_get_priority_min): Extend to return

+
+ * condvar.c (pthread_cond_destroy): fix bug with

+
+2001-08-23 Phil Frisbie, Jr. <phil at hawksoft.com>

+
+2001-07-15 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * rwlock.c (pthread_rwlock_wrlock): Is allowed to be

+ around the CV call.
+
+2001-07-10 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * barrier.c: Still more revamping. The exclusive access
+ mutex isn't really needed so it has been removed and replaced
+ by an InterlockedDecrement(). nSerial has been removed.
+ iStep is now dual-purpose. The process shared attribute
+ is now stored in the barrier struct.
+ * implement.h (pthread_barrier_t_): Lost some/gained one

+ * private.c (ptw32_threadStart): Removed some comments.
+
+2001-07-10 Ross Johnson <rpj at setup1.ise.canberra.edu.au>

+ * implement.h (pthread_barrier_t_): Revamped.
+
+2001-07-09 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * barrier.c: Fix several bugs in all routines. Now passes
+ tests/barrier5.c which is fairly rigorous. There is still
+ a non-optimal work-around for a race condition between
+ the barrier breeched event signal and event wait. Basically
+ the last (signalling) thread to hit the barrier yields
+ to allow any other threads, which may have lost the race,
+ to complete.
+
+2001-07-07 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * barrier.c: Changed synchronisation mechanism to a
+ Win32 manual reset Event and use PulseEvent to signal
+ waiting threads. If the implementation continued to use
+ a semaphore it would require a second semaphore and
+ some management to use them alternately as barriers. A
+ single semaphore allows threads to cascade from one barrier
+ through the next, leaving some threads blocked at the first.
+ * implement.h (pthread_barrier_t_): As per above.
+ * general: Made a number of other routines inlinable.
+
+2001-07-07 Ross Johnson <rpj at setup1.ise.canberra.edu.au>

+
+ * condvar.c: Fixed lost signal bug reported by Timur Aydin
+ (taydin@snet.net).
+ [RPJ (me) didn't translate the original algorithm
+ correctly.]
+ * semaphore.c: Added sem_post_multiple; this is a useful
+ routine, but it doesn't appear to be standard. For now it's
+ not an exported function.
+
+2001-06-25 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * create.c (pthread_create): Add priority inheritance
+ attributes.
+ * mutex.c (pthread_mutex_lock): Remove some overhead for
+ PTHREAD_MUTEX_NORMAL mutex types. Specifically, avoid
+ calling pthread_self() and pthread_equal() to check/set
+ the mutex owner. Introduce a new pseudo owner for this
+ type. Test results suggest increases in speed of up to
+ 90% for non-blocking locks.
+ This is the default type of mutex used internally by other
+ synchronising objects, ie. condition variables and
+ read-write locks. The test rwlock7.c shows about a
+ 30-35% speed increase over snapshot 2001-06-06. The
+ price of this is that the application developer
+ must ensure correct behaviour, or explicitly set the
+ mutex to a safer type such as PTHREAD_MUTEX_ERRORCHECK.
+ For example, PTHREAD_MUTEX_NORMAL (or PTHREAD_MUTEX_DEFAULT)
+ type mutexes will not return an error if a thread which is not
+ the owner calls pthread_mutex_unlock. The call will succeed
+ in unlocking the mutex if it is currently locked, but a
+ subsequent unlock by the true owner will then fail with EPERM.
+ This is however consistent with some other implementations.
+ (pthread_mutex_unlock): Likewise.
+ (pthread_mutex_trylock): Likewise.
+ (pthread_mutex_destroy): Likewise.
+ * attr.c (pthread_attr_init): PTHREAD_EXPLICIT_SCHED is the
+ default inheritance attribute; THREAD_PRIORITY_NORMAL is
+ the default priority for new threads.
+ * sched.c (pthread_attr_setschedpolicy): Added routine.
+ (pthread_attr_getschedpolicy): Added routine.
+ (pthread_attr_setinheritsched): Added routine.
+ (pthread_attr_getinheritsched): Added routine.
+ * pthread.h (sched_rr_set_interval): Added as a macro;
+ returns -1 with errno set to ENOSYS.
+
+2001-06-23 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ *sched.c (pthread_attr_setschedparam): Add priority range
+ check.
+ (sched_setscheduler): New function; checks for a valid
+ pid and policy; checks for permission to set information
+ in the target process; expects pid to be a Win32 process ID,
+ not a process handle; the only scheduler policy allowed is
+ SCHED_OTHER.
+ (sched_getscheduler): Likewise, but checks for permission
+ to query.
+ * pthread.h (SCHED_*): Moved to sched.h as defined in the

+
+2001-06-06 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * semaphore.h (sem_t): Is now an opaque pointer;
+ moved actual definition to implement.h.
+ * implement.h (sem_t_): Move here from semaphore.h;
+ was the definition of sem_t.
+ * semaphore.c: Wherever necessary, changed use of sem
+ from that of a pointer to a pointer-pointer; added
+ extra checks for a valid sem_t; NULL sem_t when
+ it is destroyed; added extra checks when creating
+ and destroying sem_t elements in the NEED_SEM
+ code branches; changed from using a pthread_mutex_t
+ ((*sem)->mutex) to CRITICAL_SECTION ((*sem)->sem_lock_cs)
+ in NEED_SEM branches for access serialisation.
+
+2001-06-06 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+

+
+2001-06-05 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * nonportable.c (pthread_mutex_setdefaultkind_np):

+ * pthread.h (pthread_mutex_setdefaultkind_np): Likewise.
+ (pthread_mutex_getdefaultkind_np): Likewise.
+ * pthread.def (pthread_mutexattr_setkind_np): Added.
+ (pthread_mutexattr_getkind_np): Likewise.
+
+ * README: Many changes that should have gone in before
+ the last snapshot.
+ * README.NONPORTABLE: New - referred to by ANNOUNCE
+ but never created; documents the non-portable routines
+ included in the library - moved from README with new
+ routines added.
+ * ANNOUNCE (pthread_mutexattr_setkind_np): Added to
+ compliance list.
+ (pthread_mutexattr_getkind_np): Likewise.
+
+2001-06-04 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * condvar.c: Add original description of the algorithm as
+ developed by Terekhov and Thomas, plus reference to
+ README.CV.
+
+2001-06-03 Alexander Terekhov <TEREKHOV at de.ibm.com>, Louis Thomas <lthomas at arbitrade.com>
+
+ * condvar.c (pthread_cond_init): Completely revamped.
+ (pthread_cond_destroy): Likewise.
+ (ptw32_cond_wait_cleanup): Likewise.
+ (ptw32_cond_timedwait): Likewise.
+ (ptw32_cond_unblock): New general signaling routine.
+ (pthread_cond_signal): Now calls ptw32_cond_unblock.
+ (pthread_cond_broadcast): Likewise.
+ * implement.h (pthread_cond_t_): Revamped.
+ * README.CV: New; explanation of the above changes.
+
+2001-05-30 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * pthread.h (rand_r): Fake using _seed argument to quell
+ compiler warning (compiler should optimise this away later).
+
+ * GNUmakefile (OPT): Leave symbolic information out of the library
+ and increase optimisation level - for smaller faster prebuilt
+ dlls.
+
+2001-05-29 Milan Gardian <Milan.Gardian at LEIBINGER.com>
+
+ * Makefile: fix typo.
+ * pthreads.h: Fix problems with stdcall/cdecl conventions, in particular
+ remove the need for PT_STDCALL everywhere; remove warning supression.
+ * (errno): Fix the longstanding "inconsistent dll linkage" problem
+ with errno; now also works with /MD debugging libs -
+ warnings emerged when compiling pthreads library with /MD (or /MDd)
+ compiler switch, instead of /MT (or /MTd) (i.e. when compiling pthreads
+ using Multithreaded DLL CRT instead of Multithreaded statically linked
+ CRT).
+ * create.c (pthread_create): Likewise; fix typo.
+ * private.c (ptw32_threadStart): Eliminate use of terminate() which doesn't
+ throw exceptions.
+ * Remove unnecessary #includes from a number of modules -
+ [I had to #include malloc.h in implement.h for gcc - rpj].
+
+2001-05-29 Thomas Pfaff <tpfaff at gmx.net>
+
+ * pthread.h (PTHREAD_MUTEX_DEFAULT): New; equivalent to
+ PTHREAD_MUTEX_DEFAULT_NP.
+ * (PTHREAD_MUTEX_NORMAL): Similarly.
+ * (PTHREAD_MUTEX_ERRORCHECK): Similarly.
+ * (PTHREAD_MUTEX_RECURSIVE): Similarly.
+ * (pthread_mutex_setdefaultkind_np): New; Linux compatibility stub
+ for pthread_mutexattr_settype.
+ * (pthread_mutexattr_getkind_np): New; Linux compatibility stub
+ for pthread_mutexattr_gettype.
+ * mutex.c (pthread_mutexattr_settype): New; allow
+ the following types of mutex:
+ PTHREAD_MUTEX_DEFAULT_NP
+ PTHREAD_MUTEX_NORMAL_NP
+ PTHREAD_MUTEX_ERRORCHECK_NP
+ PTHREAD_MUTEX_RECURSIVE_NP
+ * Note that PTHREAD_MUTEX_DEFAULT is equivalent to
+ PTHREAD_MUTEX_NORMAL - ie. mutexes should no longer
+ be recursive by default, and a thread will deadlock if it
+ tries to relock a mutex it already owns. This is inline with
+ other pthreads implementations.
+ * (pthread_mutex_lock): Process the lock request
+ according to the mutex type.
+ * (pthread_mutex_init): Eliminate use of Win32 mutexes as the
+ basis of POSIX mutexes - instead, a combination of one critical section
+ and one semaphore are used in conjunction with Win32 Interlocked* routines.
+ * (pthread_mutex_destroy): Likewise.
+ * (pthread_mutex_lock): Likewise.
+ * (pthread_mutex_trylock): Likewise.
+ * (pthread_mutex_unlock): Likewise.
+ * Use longjmp/setjmp to implement cancelation when building the library
+ using a C compiler which doesn't support exceptions, e.g. gcc -x c (note
+ that gcc -x c++ uses exceptions).
+ * Also fixed some of the same typos and eliminated PT_STDCALL as
+ Milan Gardian's patches above.
+
+2001-02-07 Alexander Terekhov <TEREKHOV at de.ibm.com>
+
+ * rwlock.c: Revamped.
+ * implement.h (pthread_rwlock_t_): Redefined.
+ This implementation does not have reader/writer starvation problem.
+ Rwlock attempts to behave more like a normal mutex with
+ races and scheduling policy determining who is more important;
+ It also supports recursive locking,
+ has less synchronization overhead (no broadcasts at all,
+ readers are not blocked on any condition variable) and seem to
+ be faster than the current implementation [W98 appears to be
+ approximately 15 percent faster at least - on top of speed increase
+ from Thomas Pfaff's changes to mutex.c - rpj].
+
+2000-12-29 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * Makefile: Back-out "for" loops which don't work.
+
+ * GNUmakefile: Remove the fake.a target; add the "realclean"
+ target; don't remove built libs under the "clean" target.
+
+ * config.h: Add a guard against multiple inclusion.
+
+ * semaphore.h: Add some defines from config.h to make
+ semaphore.h independent of config.h when building apps.
+
+ * pthread.h (_errno): Back-out previous fix until we know how to
+ fix it properly.
+
+ * implement.h (lockCount): Add missing element to pthread_mutex_t_.
+
+ * sync.c (pthread_join): Spelling fix in comment.
+
+ * private.c (ptw32_threadStart): Reset original termination
+ function (C++).
+ (ptw32_threadStart): Cleanup detached threads early in case
+ the library is statically linked.
+ (ptw32_callUserDestroyRoutines): Remove [SEH] __try block from
+ destructor call so that unhandled exceptions will be passed through
+ to the system; call terminate() from [C++] try block for the same
+ reason.
+
+ * tsd.c (pthread_getspecific): Add comment.
+
+ * mutex.c (pthread_mutex_init): Initialise new elements in
+ pthread_mutex_t.
+ (pthread_mutex_unlock): Invert "pthread_equal()" test.
+
+2000-12-28 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * semaphore.c (mode_t): Use ifndef HAVE_MODE_T to include definition.
+
+ * config.h.in (HAVE_MODE_T): Added.
+ (_UWIN): Start adding defines for the UWIN package.
+
+ * private.c (ptw32_threadStart): Unhandled exceptions are
+ now passed through to the system to deal with. This is consistent
+ with normal Windows behaviour. C++ applications may use
+ set_terminate() to override the default behaviour which is
+ to call ptw32_terminate(). Ptw32_terminate() cleans up some
+ POSIX thread stuff before calling the system default function
+ which calls abort(). The users termination function should conform
+ to standard C++ semantics which is to not return. It should
+ exit the thread (call pthread_exit()) or exit the application.
+ * private.c (ptw32_terminate): Added as the default set_terminate()
+ function. It calls the system default function after cleaning up
+ some POSIX thread stuff.
+
+ * implement.h (ptw32_try_enter_critical_section): Move
+ declaration.
+ * global.c (ptw32_try_enter_critical_section): Moved
+ from dll.c.
+ * dll.c: Move process and thread attach/detach code into
+ functions in nonportable.c.
+ * nonportable.c (pthread_win32_process_attach_np): Process
+ attach code from dll.c is now available to static linked
+ applications.
+ * nonportable.c (pthread_win32_process_detach_np): Likewise.
+ * nonportable.c (pthread_win32_thread_attach_np): Likewise.
+ * nonportable.c (pthread_win32_thread_detach_np): Likewise.
+
+ * pthread.h: Add new non-portable prototypes for static
+ linked applications.
+
+ * GNUmakefile (OPT): Increase optimisation flag and remove
+ debug info flag.
+
+ * pthread.def: Add new non-portable exports for static
+ linked applications.
+
+2000-12-11 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * FAQ: Update Answer 6 re getting a fully working
+ Mingw32 built library.
+
+2000-10-10 Steven Reddie <smr at essemer.com.au>
+
+ * misc.c (pthread_self): Restore Win32 "last error"
+ cleared by TlsGetValue() call in
+ pthread_getspecific()
+
+2000-09-20 Arthur Kantor <akantor at bexusa.com>
+
+ * mutex.c (pthread_mutex_lock): Record the owner
+ of the mutex. This requires also keeping count of
+ recursive locks ourselves rather than leaving it
+ to Win32 since we need to know when to NULL the
+ thread owner when the mutex is unlocked.
+ (pthread_mutex_trylock): Likewise.
+ (pthread_mutex_unlock): Check that the calling
+ thread owns the mutex, decrement the recursive
+ lock count, and NULL the owner if zero. Return
+ EPERM if the mutex is owned by another thread.
+ * implement.h (pthread_mutex_t_): Add ownerThread
+ and lockCount members.
+
+2000-09-13 Jef Gearhart <jgearhart at tpssys.com>
+
+ * mutex.c (pthread_mutex_init): Call
+ TryEnterCriticalSection through the pointer
+ rather than directly so that the dll can load
+ on Windows versions that can't resolve the
+ function, eg. Windows 95
+
+2000-09-09 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h (ctime_r): Fix arg.
+
+2000-09-08 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * GNUmakefile(_WIN32_WINNT=0x400): Define in CFLAGS;
+ doesn't seem to be needed though.
+
+ * cancel.c (pthread_cancel): Must get "self" through
+ calling pthread_self() which will ensure a POSIX thread
+ struct is built for non-POSIX threads; return an error
+ if this fails
+ - Ollie Leahy <ollie at mpt.ie>
+ (pthread_setcancelstate): Likewise.
+ (pthread_setcanceltype): Likewise.
+ * misc.c (ptw32_cancelable_wait): Likewise.
+
+ * private.c (ptw32_tkAssocCreate): Remove unused #if 0
+ wrapped code.
+
+ * pthread.h (ptw32_get_exception_services_code):
+ Needed to be forward declared unconditionally.
+
+2000-09-06 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * cancel.c (pthread_cancel): If called from the main
+ thread "self" would be NULL; get "self" via pthread_self()
+ instead of directly from TLS so that an implicit
+ pthread object is created.
+
+ * misc.c (pthread_equal): Strengthen test for NULLs.
+
+2000-09-02 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * condvar.c (ptw32_cond_wait_cleanup): Ensure that all
+ waking threads check if they are the last, and notify
+ the broadcaster if so - even if an error occurs in the
+ waiter.
+
+ * semaphore.c (_decrease_semaphore): Should be
+ a call to ptw32_decrease_semaphore.
+ (_increase_semaphore): Should be a call to
+ ptw32_increase_semaphore.
+
+ * misc.c (ptw32_cancelable_wait): Renamed from
+ CancelableWait.
+ * rwlock.c (_rwlock_check*): Renamed to
+ ptw32_rwlock_check*.
+ * mutex.c (_mutex_check*): Renamed to ptw32_mutex_check*.
+ * condvar.c (cond_timed*): Renamed to ptw32_cond_timed*.

+ (ptw32_cond_timedwait): Add comments.
+
+2000-08-22 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * private.c (ptw32_throw): Fix exception test;

+
+ * tsd.c (pthread_key_create): newkey wrongly declared.
+
+ * pthread.h: Fix comment block.
+
+2000-08-18 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * mutex.c (pthread_mutex_destroy): Check that the mutex isn't
+ held; invalidate the mutex as early as possible to avoid
+ contention; not perfect - FIXME!
+
+ * rwlock.c (pthread_rwlock_init): Remove redundant assignment
+ to "rw".
+ (pthread_rwlock_destroy): Invalidate the rwlock before
+ freeing up any of it's resources - to avoid contention.
+
+ * private.c (ptw32_tkAssocCreate): Change assoc->lock
+ to use a dynamically initialised mutex - only consumes
+ a W32 mutex or critical section when first used,
+ not before.
+
+ * mutex.c (pthread_mutex_init): Remove redundant assignment
+ to "mx".
+ (pthread_mutexattr_destroy): Set attribute to NULL
+ before freeing it's memory - to avoid contention.
+
+ * implement.h (PTW32_EPS_CANCEL/PTW32_EPS_EXIT):
+ Must be defined for all compilers - used as generic
+ exception selectors by ptw32_throw().
+
+ * Several: Fix typos from scripted edit session
+ yesterday.
+
+ * nonportable.c (pthread_mutexattr_setforcecs_np):
+ Moved this function from mutex.c.
+ (pthread_getw32threadhandle_np): New function to
+ return the win32 thread handle that the POSIX
+ thread is using.
+ * mutex.c (pthread_mutexattr_setforcecs_np):
+ Moved to new file "nonportable.c".
+
+ * pthread.h (PTW32_BUILD): Only redefine __except
+ and catch compiler keywords if we aren't building
+ the library (ie. PTW32_BUILD is not defined) -
+ this is safer than defining and then undefining
+ if not building the library.
+ * implement.h: Remove __except and catch undefines.
+ * Makefile (CFLAGS): Define PTW32_BUILD.
+ * GNUmakefile (CFLAGS): Define PTW32_BUILD.
+
+ * All appropriate: Change Pthread_exception* to
+ ptw32_exception* to be consistent with internal
+ identifier naming.
+
+ * private.c (ptw32_throw): New function to provide
+ a generic exception throw for all internal
+ exceptions and EH schemes.
+ (ptw32_threadStart): pthread_exit() value is now
+ returned via the thread structure exitStatus
+ element.
+ * exit.c (pthread_exit): pthread_exit() value is now
+ returned via the thread structure exitStatus
+ element.
+ * cancel.c (ptw32_cancel_self): Now uses ptw32_throw.
+ (pthread_setcancelstate): Ditto.
+ (pthread_setcanceltype): Ditto.
+ (pthread_testcancel): Ditto.
+ (pthread_cancel): Ditto.
+ * misc.c (CancelableWait): Ditto.
+ * exit.c (pthread_exit): Ditto.
+ * All applicable: Change PTW32_ prefix to
+ PTW32_ prefix to remove leading underscores
+ from private library identifiers.
+
+2000-08-17 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * All applicable: Change _pthread_ prefix to
+ ptw32_ prefix to remove leading underscores
+ from private library identifiers (single
+ and double leading underscores are reserved in the
+ ANSI C standard for compiler implementations).
+
+ * tsd.c (pthread_create_key): Initialise temporary
+ key before returning it's address to avoid race
+ conditions.
+
+2000-08-13 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * errno.c: Add _MD precompile condition; thus far
+ had no effect when using /MD compile option but I
+ thnk it should be there.
+
+ * exit.c: Add __cplusplus to various #if lines;
+ was compiling SEH code even when VC++ had
+ C++ compile options.
+
+ * private.c: ditto.
+
+ * create.c (pthread_create): Add PT_STDCALL macro to
+ function pointer arg in _beginthread().
+
+ * pthread.h: PT_STDCALL really does need to be defined
+ in both this and impliment.h; don't set it to __cdecl
+ - this macro is only used to extend function pointer
+ casting for functions that will be passed as parameters.
+ (~PThreadCleanup): add cast and group expression.
+ (_errno): Add _MD compile conditional.
+ (PtW32NoCatchWarn): Change pragma message.
+
+ * implement.h: Move and change PT_STDCALL define.
+
+ * need_errno.h: Add _MD to compilation conditional.
+
+ * GNUmakefile: Substantial rewrite for new naming
+ convention; set for nil optimisation (turn it up
+ when we have a working library build; add target
+ "fake.a" to build a libpthreadw32.a from the VC++
+ built DLL pthreadVCE.dll.
+
+ * pthread.def (LIBRARY): Don't specify in the .def
+ file - it is specified on the linker command line
+ since we now use the same .def file for variously
+ named .dlls.
+
+ * Makefile: Substantial rewrite for new naming
+ convention; default nmake target only issues a
+ help message; run nmake with specific target
+ corresponding to the EH scheme being used.
+
+ * README: Update information; add naming convention
+ explanation.
+
+ * ANNOUNCE: Update information.
+
+2000-08-12 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h: Add compile-time message when using
+ MSC_VER compiler and C++ EH to warn application
+ programmers to use PtW32Catch instead of catch(...)
+ if they want cancelation and pthread_exit to work.
+
+ * implement.h: Remove #include <semaphore.h>; we
+ use our own local semaphore.h.
+
+2000-08-10 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * cleanup.c (pthread_pop_cleanup): Remove _pthread
+ prefix from __except and catch keywords; implement.h
+ now simply undefines ptw32__except and
+ ptw32_catch if defined; VC++ was not textually
+ substituting ptw32_catch etc back to catch as
+ it was redefined; the reason for using the prefixed
+ version was to make it clear that it was not using
+ the pthread.h redefined catch keyword.
+
+ * private.c (ptw32_threadStart): Ditto.
+ (ptw32_callUserDestroyRoutines): Ditto.
+
+ * implement.h (ptw32__except): Remove #define.
+ (ptw32_catch): Remove #define.
+
+ * GNUmakefile (pthread.a): New target to build
+ libpthread32.a from pthread.dll using dlltool.
+
+ * buildlib.bat: Duplicate cl commands with args to
+ build C++ EH version of pthread.dll; use of .bat
+ files is redundant now that nmake compatible
+ Makefile is included; used as a kludge only now.
+
+ * Makefile: Localise some macros and fix up the clean:
+ target to extend it and work properly.
+
+ * CONTRIBUTORS: Add contributors.
+
+ * ANNOUNCE: Updated.
+
+ * README: Updated.
+
+2000-08-06 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h: Remove #warning - VC++ doesn't accept it.
+
+2000-08-05 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h (PtW32CatchAll): Add macro. When compiling
+ applications using VC++ with C++ EH rather than SEH
+ 'PtW32CatchAll' must be used in place of any 'catch( ... )'
+ if the application wants pthread cancelation or
+ pthread_exit() to work.
+
+2000-08-03 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h: Add a base class ptw32_exception for

+ re-define macro to use it.
+
+2000-08-02 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * GNUmakefile (CFLAGS): Add -mthreads.

+ * sync.c (pthread_join): Remove dead code.
+
+2000-07-25 Tristan Savatier <tristan at mpegtv.com>
+
+ * sched.c (sched_get_priority_max): Handle different WinCE and

+ (sched_get_priority_min): Ditto.
+
+2000-07-25 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * create.c (pthread_create): Force new threads to wait until
+ pthread_create has the new thread's handle; we also retain
+ a local copy of the handle for internal use until
+ pthread_create returns.
+
+ * private.c (ptw32_threadStart): Initialise ei[].
+ (ptw32_threadStart): When beginthread is used to start the
+ thread, force waiting until the creator thread had the
+ thread handle.
+
+ * cancel.c (ptw32_cancel_thread): Include context switch
+ code for defined(_X86_) environments in addition to _M_IX86.
+
+ * rwlock.c (pthread_rwlock_destroy): Assignment changed
+ to avoid compiler warning.
+
+ * private.c (ptw32_get_exception_services_code): Cast
+ NULL return value to avoid compiler warning.
+
+ * cleanup.c (pthread_pop_cleanup): Initialise "cleanup" variable
+ to avoid compiler warnings.
+
+ * misc.c (ptw32_new): Change "new" variable to "t" to avoid

+
+ * condvar.c (cond_wait_cleanup): Initialise lastWaiter variable.
+ (cond_timedwait): Remove unused local variables. to avoid
+ compiler warnings.
+
+ * dll.c (dllMain): Remove 2000-07-21 change - problem
+ appears to be in pthread_create().
+
+2000-07-22 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * tsd.c (pthread_key_create): If a destructor was given
+ and the pthread_mutex_init failed, then would try to
+ reference a NULL pointer (*key); eliminate this section of
+ code by using a dynamically initialised mutex
+ (PTHREAD_MUTEX_INITIALIZER).
+
+ * tsd.c (pthread_setspecific): Return an error if
+ unable to set the value; simplify cryptic conditional.
+
+ * tsd.c (pthread_key_delete): Locking threadsLock relied
+ on mutex_lock returning an error if the key has no destructor.
+ ThreadsLock is only initialised if the key has a destructor.
+ Making this mutex a static could reduce the number of mutexes
+ used by an application since it is actually created only at
+ first use and it's often destroyed soon after.
+
+2000-07-22 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * FAQ: Added Q5 and Q6.
+
+2000-07-21 David Baggett <dmb at itasoftware.com>

+
+2000-07-21 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * create.c (pthread_create): Set threadH to 0 (zero)
+ everywhere. Some assignments were using NULL. Maybe
+ it should be NULL everywhere - need to check. (I know
+ they are nearly always the same thing - but not by
+ definition.)
+
+ * misc.c (pthread_self): Try to catch NULL thread handles
+ at the point where they might be generated, even though
+ they should always be valid at this point.
+
+ * tsd.c (pthread_setspecific): return an error value if

+
+2000-01-28 Ross Johnson <rpj at special.ise.canberra.edu.au>

+
+ * pthread.h (ptw32_exception_services): Remove extern.
+ (ptw32_get_exception_services_code): Add function prototype;

+ Define '_timeb' as 'timeb' for Ming32.
+ Define PT_STDCALL as nothing for Mingw32. May be temporary.
+
+ * cancel.c (pthread_testcancel): Cast return value.
+
+Wed Jan 20 09:31:28 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * pthread.h (pthread_mutexattr_t): Changed to a pointer.
+
+ * mutex.c (pthread_mutex_init): Conditionally create Win32 mutex
+ - from John Bossom's implementation.
+ (pthread_mutex_destroy): Conditionally close Win32 mutex
+ - from John Bossom's implementation.
+ (pthread_mutexattr_init): Replaced by John Bossom's version.
+ (pthread_mutexattr_destroy): Ditto.
+ (pthread_mutexattr_getpshared): New function from John Bossom's

+
+Tue Jan 19 18:27:42 1999 Ross Johnson <rpj at swan.canberra.edu.au>
+
+ * pthread.h (pthreadCancelableTimedWait): New prototype.
+ (pthreadCancelableWait): Remove second argument.
+
+ * misc.c (CancelableWait): New static function is
+ pthreadCancelableWait() renamed.
+ (pthreadCancelableWait): Now just calls CancelableWait() with
+ INFINITE timeout.
+ (pthreadCancelableTimedWait): Just calls CancelableWait()
+ with passed in timeout.
+
+Tue Jan 19 18:27:42 1999 Scott Lightner <scott at curriculum.com>
+
+ * private.c (ptw32_sem_timedwait): 'abstime' arg really is
+ absolute time. Calculate relative time to wait from current
+ time before passing timeout to new routine
+ pthreadCancelableTimedWait().
+
+Tue Jan 19 10:27:39 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * pthread.h (pthread_mutexattr_setforcecs_np): New prototype.
+
+ * mutex.c (pthread_mutexattr_init): Init 'pshared' and 'forcecs'
+ attributes to 0.
+ (pthread_mutexattr_setforcecs_np): New function (not portable).
+
+ * pthread.h (pthread_mutex_t):
+ Add 'mutex' element. 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. On Win9x, and early
+ versions of NT 'forcecs' will need to be set in order to get
+ critical section based mutexes.
+
+Sun Jan 17 12:01:26 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * pthread.h (PTHREAD_MUTEX_INITIALIZER): Init new 'staticinit'
+ value to '1' and existing 'valid' value to '1'.
+
+ * global.c (ptw32_mutex_test_init_lock): Add.
+
+ * implement.h (ptw32_mutex_test_init_lock.): Add extern.
+
+ * private.c (ptw32_processInitialize): Init critical section for
+ global lock used by _mutex_check_need_init().
+ (ptw32_processTerminate): Ditto (:s/Init/Destroy/).
+
+ * dll.c (dllMain): Move call to FreeLibrary() so that it is only
+ called once when the process detaches.
+
+ * mutex.c (_mutex_check_need_init): New static function to test
+ and init PTHREAD_MUTEX_INITIALIZER mutexes. 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 <rpj at ixobrychus.canberra.edu.au>
+
+ * 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 <rpj at ixobrychus.canberra.edu.au>
+
+ * condvar.c (cond_timedwait): Remove comment.
+
+Fri Jan 15 15:41:28 1999 Ross Johnson <rpj at swan.canberra.edu.au>
+
+ * 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 <rpj at swan.canberra.edu.au>
+
+ * 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 <rpj at ixobrychus.canberra.edu.au>
+
+ * build.bat: Delete old binaries before compiling/linking.
+
+Tue Jan 12 09:58:38 1999 Tor Lillqvist <tml at iki.fi>
+
+ * dll.c: The Microsoft compiler pragmas probably are more
+ appropriately protected by _MSC_VER than by _WIN32.
+
+ * pthread.h: Define ETIMEDOUT. This should be returned by
+ pthread_cond_timedwait which is not implemented yet as of
+ snapshot-1999-01-04-1305. It was implemented in the older version.
+ The Microsoft compiler pragmas probably are more appropriately
+ protected by _MSC_VER than by _WIN32.
+
+ * pthread.def: pthread_mutex_destroy was missing from the def file
+
+ * condvar.c (pthread_cond_broadcast): Ensure we only wait on threads
+ if there were any waiting on the condition.
+ I think pthread_cond_broadcast should do the WaitForSingleObject
+ only if cv->waiters > 0? Otherwise it seems to hang, at least in the
+ testg thread program from glib.
+
+Tue Jan 12 09:58:38 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * condvar.c (pthread_cond_timedwait): Fix function description
+ comments.
+
+ * semaphore.c (sem_post): Correct typo in comment.
+
+Mon Jan 11 20:33:19 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * pthread.h: Re-arrange conditional compile of pthread_cleanup-*
+ macros.
+
+ * cleanup.c (ptw32_push_cleanup): Provide conditional
+ compile of cleanup->prev.
+
+1999-01-11 Tor Lillqvist <tml at iki.fi>
+
+ * condvar.c (pthread_cond_init): Invert logic when testing the
+ return value from calloc().
+
+Sat Jan 9 14:32:08 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * implement.h: Compile-time switch for CYGWIN derived environments
+ to use CreateThread instead of _beginthreadex. Ditto for ExitThread.
+ Patch provided by Anders Norlander <anorland at hem2.passagen.se>.
+
+Tue Jan 5 16:33:04 1999 Ross Johnson <rpj at swan.canberra.edu.au>
+
+ * cleanup.c (ptw32_pop_cleanup): Add C++ version of __try/__except
+ block. Move trailing "}" out of #ifdef _WIN32 block left there by
+ (rpj's) mistake.
+
+ * private.c: Remove #include <errno.h> which is included by pthread.h.
+
+1998-12-11 Ben Elliston <bje at toilet.to.cygnus.com>
+
+ * README: Update info about subscribing to the mailing list.
+
+Mon Jan 4 11:23:40 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * all: No code changes, just cleanup.
+ - remove #if 0 /* Pre Bossom */ enclosed code.
+ - Remove some redundant #includes.
+ * pthread.h: Update implemented/unimplemented routines list.
+ * Tag the bossom merge branch getting ready to merge back to main
+ trunk.

+ In the WIN32 version __finally block, add a test for AbnormalTermination otherwise
+ cleanup is only run if the cleanup_pop execute arg is non-zero. Cancellation

+ that attribute instead of a separate flag.
+
+ * create.c (pthread_create): Rename "this" to "us".
+ (pthread_create): cancelstate and canceltype are not attributes

+=============================================================================
+
+Q 1 What is it?
+---
+
+Pthreads-win32 is an Open Source Software implementation of the
+Threads component of the POSIX 1003.1c 1995 Standard for Microsoft's
+Win32 environment. Some functions from POSIX 1003.1b are also
+supported including semaphores. Other related functions include
+the set of read-write lock functions. The library also supports
+some of the functionality of the Open Group's Single Unix
+specification, version 2, namely mutex types.
+
+See the file "ANNOUNCE" for more information including standards
+conformance details and list of supported routines.
+
+
+------------------------------------------------------------------------------
+
+Q 2 Which of the several dll versions do I use?
+--- or,
+ What are all these pthread*.dll and pthread*.lib files?
+
+Simply, you only use one of them, but you need to choose carefully.
+
+The most important choice you need to make is whether to use a
+version that uses exceptions internally, or not (there are versions
+of the library that use exceptions as part of the thread
+cancelation and cleanup implementation, and one that uses
+setjmp/longjmp instead).
+
+There is some contension amongst POSIX threads experts as
+to how POSIX threads cancelation and exit should work
+with languages that include exceptions and handlers, e.g.
+C++ and even C (Microsoft's Structured Exceptions).
+
+The issue is: should cancelation of a thread in, say,
+a C++ application cause object destructors and C++ exception
+handlers to be invoked as the stack unwinds during thread
+exit, or not?
+
+There seems to be more opinion in favour of using the
+standard C version of the library (no EH) with C++ applications
+since this appears to be the assumption commercial pthreads
+implementations make. Therefore, if you use an EH version
+of pthreads-win32 then you may be under the illusion that
+your application will be portable, when in fact it is likely to
+behave very differently linked with other pthreads libraries.
+
+Now you may be asking: why have you kept the EH versions of
+the library?
+
+There are a couple of reasons:
+- there is division amongst the experts and so the code may
+ be needed in the future. (Yes, it's in the repository and we
+ can get it out anytime in the future, but ...)
+- pthreads-win32 is one of the few implementations, and possibly
+ the only freely available one, that has EH versions. It may be
+ useful to people who want to play with or study application
+ behaviour under these conditions.
+
+
+------------------------------------------------------------------------------
+
+Q 3 What is the library naming convention?
+---
+
+Because the library is being built using various exception
+handling schemes and compilers - and because the library
+may not work reliably if these are mixed in an application,
+each different version of the library has it's own name.
+
+Note 1: the incompatibility is really between EH implementations
+of the different compilers. It should be possible to use the
+standard C version from either compiler with C++ applications
+built with a different compiler. If you use an EH version of
+the library, then you must use the same compiler for the
+application. This is another complication and dependency that
+can be avoided by using only the standard C library version.
+
+Note 2: if you use a standard C pthread*.dll with a C++
+application, then any functions that you define that are
+intended to be called via pthread_cleanup_push() must be
+__cdecl.
+
+Note 3: the intention is to also name either the VC or GC
+version (it should be arbitrary) as pthread.dll, including
+pthread.lib and libpthread.a as appropriate.
+
+In general:
+ pthread[VG]{SE,CE,C}.dll
+ pthread[VG]{SE,CE,C}.lib
+
+where:
+ [VG] indicates the compiler
+ V - MS VC
+ G - GNU C
+
+ {SE,CE,C} indicates the exception handling scheme
+ SE - Structured EH
+ CE - C++ EH
+ C - no exceptions - uses setjmp/longjmp
+
+For example:
+ pthreadVSE.dll (MSVC/SEH)
+ pthreadGCE.dll (GNUC/C++ EH)
+ pthreadGC.dll (GNUC/not dependent on exceptions)
+
+The GNU library archive file names have changed to:
+
+ libpthreadGCE.a
+ libpthreadGC.a
+
+
+------------------------------------------------------------------------------
+
+Q 4 Cleanup code default style or: it used to work when I built
+--- the library myself, but now it doesn't - why?
+
+Up to and including snapshot 2001-07-12, if not defined, the cleanup
+style was determined automatically from the compiler used, 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().
+
+After snapshot 2001-07-12, unless your 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/all
+commercial Unix POSIX threads implementations.
+
+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
+
+THE POINT OF ALL THIS IS: if you have not been defining one of these
+explicitly, then the defaults have been set according to the compiler
+and language you are using, as described at the top of this
+section.
+
+THIS NOW CHANGES, as has been explained above. For example:
+
+If you were building your application with MSVC++ i.e. using C++
+exceptions (rather than SEH) and not explicitly defining one of
+__CLEANUP_*, then __CLEANUP_C++ was 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
+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, nor when 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 local
+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.
+
+
+------------------------------------------------------------------------------
+
+Q 5 Why is the default library version now less exception-friendly?
+---
+
+Because most commercial Unix POSIX threads implementations don't allow you to
+choose to have stack unwinding. (Compaq's TRU64 Unix is possibly an exception.)
+
+Therefore, providing it in pthread-win32 as a default could be dangerous
+and non-portable. We still provide the choice but you must now consciously
+make it.
+
+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.)
+- 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.
+
+
+------------------------------------------------------------------------------
+
+Q 6 Should I use Cygwin or Mingw32 as a development environment?
+---
+
+Important: see Q7 also.
+
+Use Mingw32 with the MSVCRT library to build applications that use
+the pthreads DLL.
+
+Cygwin's own internal support for POSIX threads is growing.
+Consult that project's documentation for more information.
+
+------------------------------------------------------------------------------
+
+Q 7 Now that pthreads-win32 builds under Mingw32, why do I get
+--- memory access violations (segfaults)?
+
+The latest Mingw32 package has thread-safe exception handling (see Q10).
+Also, see Q6 above.
+

+

+
+You should have a .dll, .lib, .def, and three .h files. It is recommended
+that you use pthreadVC.dll, rather than pthreadVCE.dll or pthreadVSE.dll
+(see Q2 above).
+
+The .dll can go in any directory listed in your PATH environment
+variable, so putting it into C:\WINDOWS should work.
+
+The .lib file can go in any directory listed in your LIB environment
+variable.
+
+The .h files can go in any directory listed in your INCLUDE
+environment variable.
+
+Or you might prefer to put the .lib and .h files into a new directory
+and add its path to LIB and INCLUDE. You can probably do this easiest
+by editing the file:-
+
+C:\Program Files\DevStudio\vc\bin\vcvars32.bat
+
+The .def file isn't used by anything in the pre-compiled version but
+is included for information.

+
+The answer to your first question is, normal POSIX behaviour would
+be to asynchronously cancel the thread. However, even that doesn't
+guarantee cancelation as the standard only says it should be
+cancelled as soon as possible.
+
+Snapshot 99-11-02 or earlier only partially supports asynchronous cancellation.
+Snapshots since then simulate async cancelation by poking the address of
+a cancelation routine into the PC of the threads context. This requires
+the thread to be resumed in some way for the cancelation to actually
+proceed. This is not true async cancelation, but it is as close as we've
+been able to get to it.
+
+If the thread you're trying to cancel is blocked (for instance, it could be
+waiting for data from the network), it will only get cancelled when it unblocks
+(when the data arrives). For true pre-emptive cancelation in these cases,
+pthreads-win32 from snapshot 2004-05-16 can automatically recognise and use the
+QueueUserAPCEx package by Panagiotis E. Hadjidoukas. This package is available
+from the pthreads-win32 ftp site and is included in the pthreads-win32
+self-unpacking zip from 2004-05-16 onwards.
+
+Using deferred cancelation would normally be the way to go, however,
+even though the POSIX threads standard lists a number of C library
+functions that are defined as deferred cancelation points, there is
+no hookup between those which are provided by Windows and the
+pthreads-win32 library.
+
+Incidently, it's worth noting for code portability that the older POSIX
+threads standards cancelation point lists didn't include "select" because
+(as I read in Butenhof) it wasn't part of POSIX. However, it does appear in
+the SUSV3.
+
+Effectively, the only mandatory cancelation points that pthreads-win32
+recognises are those the library implements itself, ie.
+
+ pthread_testcancel
+ pthread_cond_wait
+ pthread_cond_timedwait
+ pthread_join
+ sem_wait
+ sem_timedwait
+ pthread_delay_np

+
+The following routines from the non-mandatory list in SUSV3 are not
+cancelation points in pthreads-win32:
+
+ pthread_rwlock_rdlock
+ pthread_rwlock_timedrdlock
+
+Pthreads-win32 also provides two functions that allow you to create
+cancelation points within your application, but only for cases where
+a thread is going to block on a Win32 handle. These are:
+
+ pthreadCancelableWait(HANDLE waitHandle) /* Infinite wait */
+
+ pthreadCancelableTimedWait(HANDLE waitHandle, DWORD timeout)

+Q 10 How do I create thread-safe applications using
+---- pthreadGCE.dll, libpthreadw32.a and Mingw32?
+
+This should not be a problem with recent versions of MinGW32.
+
+For early versions, see Thomas Pfaff's email at:
+http://sources.redhat.com/ml/pthreads-win32/2002/msg00000.html
+------------------------------------------------------------------------------
+
+Q 11 Why isn't pthread_t defined as a scalar (e.g. pointer or int)
+ like it is for other POSIX threads implementations?
+----
+
+Originally pthread_t was defined as a pointer (to the opaque pthread_t_
+struct) and later it was changed to a struct containing the original
+pointer plus a sequence counter. This is allowed under both the original
+POSIX Threads Standard and the current Single Unix Specification.
+
+When pthread_t is a simple pointer to a struct some very difficult to
+debug problems arise from the process of freeing and later allocing
+thread structs because new pthread_t handles can acquire the identity of
+previously detached threads. The change to a struct was made, along with
+some changes to their internal managment, in order to guarantee (for
+practical applications) that the pthread_t handle will be unique over the
+life of the running process.
+
+Where application code attempts to compare one pthread_t against another
+directly, a compiler error will be emitted because structs can't be
+compared at that level. This should signal a potentially serious problem
+in the code design, which would go undetected if pthread_t was a scalar.
+
+The POSIX Threading API provides a function named pthread_equal() to
+compare pthread_t thread handles.
+
+Other pthreads implementations, such as Sun's, use an int as the handle
+but do guarantee uniqueness within the process scope. Win32 scalar typed
+thread handles also guarantee uniqueness in system scope. It wasn't clear
+how well the internal management of these handles would scale as the
+number of threads and the fragmentation of the sequence numbering
+increased for applications where thousands or millions of threads are
+created and detached over time. The current management of threads within
+pthreads-win32 using structs for pthread_t, and reusing without ever
+freeing them, reduces the management time overheads to a constant, which
+could be important given that pthreads-win32 threads are built on top of
+Win32 threads and will therefore include that management overhead on top
+of their own. The cost is that the memory resources used for thread
+handles will remain at the peak level until the process exits.
+
+While it may be inconvenient for developers to be forced away from making
+assumptions about the internals of pthread_t, the advantage for the
+future development of pthread-win32, as well as those applications that
+use it and other pthread implementations, is that the library is free to
+change pthread_t internals and management as better methods arise.

+# facilitate development of applications on Win32 that will be ported
+# to other POSIX systems. 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"

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 <RKubis at mc.com> - -* 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 <beowinkle at yahoo.com> - - -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 <tristan at mpegtv.com> - -* 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 <anuj.goyal at gmail.com> - -* 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 <Alex.Blanco at motorola.com> - -* ptw32_getprocessors() now returns CPU count of 1 for WinCE. -- James Ewing <james.ewing at sveasoft.com> - -* pthread_cond_wait() could be canceled at a point where it should not -be cancelable. Fixed. -- Alexander Terekhov <TEREKHOV at de.ibm.com> - -* sem_timedwait() had an incorrect timeout calculation. -- Philippe Di Cristo <philipped at voicebox.com> - -* Fix a memory leak left behind after threads are destroyed. -- P. van Bruggen <pietvb at newbridges.nl> - -New features ------------- -* Ported to AMD64. -- Makoto Kato <raven at oldskool.jp> - -* 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 <vcotirlea@hotmail.com> - -* pthread_win32_process_detach_np() fixed memory leak. -- Steven Reddie <Steven.Reddie@ca.com> - -* pthread_mutex_destroy() fixed incorrect return code. -- Nicolas Barry <boozai@yahoo.com> - -* pthread_spin_destroy() fixed memory leak. -- Piet van Bruggen <pietvb@newbridges.nl> - -* 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 <boozai@yahoo.com> - -* 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 <tpfaff@gmx.net> - -* pthread_mutex_timedlock() no longer occasionally sets incorrect mutex -ownership, causing deadlocks in some applications. -- Robert Strycek <strycek@posam.sk> and Alexander Terekhov <TEREKHOV@de.ibm.com> - - -SNAPSHOT 2002-11-04 -------------------- - -Bug fixes ---------- - -* sem_getvalue() now returns the correct value under Win NT and WinCE. -- Rob Fanner <rfanner@stonethree.com> - -* 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.

(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 <scott@magruder.org> - -* Removed potential race condition in pthread_mutex_trylock and -pthread_mutex_lock; -- Alexander Terekhov <TEREKHOV@de.ibm.com> - -* 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 <tpfaff@gmx.net> - -* 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.

+RELEASE 2.9.0 pending
+-------------
+(2010-??-??)
+
+General
+-------
+New bug 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

+Bug fixes
+---------

+- Konstantin Voronkov <beowinkle at yahoo.com>
+
+
+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 <tristan at mpegtv.com>
+
+* 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 <anuj.goyal at gmail.com>
+
+* 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 <Alex.Blanco at motorola.com>
+
+* ptw32_getprocessors() now returns CPU count of 1 for WinCE.
+- James Ewing <james.ewing at sveasoft.com>
+
+* pthread_cond_wait() could be canceled at a point where it should not
+be cancelable. Fixed.
+- Alexander Terekhov <TEREKHOV at de.ibm.com>
+
+* sem_timedwait() had an incorrect timeout calculation.
+- Philippe Di Cristo <philipped at voicebox.com>
+
+* Fix a memory leak left behind after threads are destroyed.
+- P. van Bruggen <pietvb at newbridges.nl>
+
+New features
+------------
+* Ported to AMD64.
+- Makoto Kato <raven at oldskool.jp>
+
+* 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.

+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 <tpfaff@gmx.net>
+
+* pthread_mutex_timedlock() no longer occasionally sets incorrect mutex

+
+Bug fixes
+---------
+
+* sem_getvalue() now returns the correct value under Win NT and WinCE.
+- Rob Fanner <rfanner@stonethree.com>
+
+* 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 <TEREKHOV@de.ibm.com>
+
+* 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.

+
+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 <scott@magruder.org>
+
+* Removed potential race condition in pthread_mutex_trylock and
+pthread_mutex_lock;
+- Alexander Terekhov <TEREKHOV@de.ibm.com>
+
+* 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 <tpfaff@gmx.net>
+
+* 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.

+Non-portable functions included in pthreads-win32
+-------------------------------------------------
+
+BOOL
+pthread_win32_test_features_np(int mask)
+
+ This routine allows an application to check which
+ run-time auto-detected features are available within
+ the library.
+
+ The possible features are:
+
+ PTW32_SYSTEM_INTERLOCKED_COMPARE_EXCHANGE
+ Return TRUE if the native version of
+ InterlockedCompareExchange() is being used.
+ PTW32_ALERTABLE_ASYNC_CANCEL
+ Return TRUE is the QueueUserAPCEx package
+ QUSEREX.DLL is available and the AlertDrv.sys
+ driver is loaded into Windows, providing
+ alertable (pre-emptive) asyncronous threads
+ cancelation. If this feature returns FALSE
+ then the default async cancel scheme is in
+ use, which cannot cancel blocked threads.
+
+ Features may be Or'ed into the mask parameter, in which case
+ the routine returns TRUE if any of the Or'ed features would
+ return TRUE. At this stage it doesn't make sense to Or features
+ but it may some day.
+
+
+void *
+pthread_timechange_handler_np(void *)
+
+ 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.
+
+ It has the same return type and argument type as a
+ thread routine so that it may be called directly
+ through pthread_create(), i.e. as a separate thread.
+
+ Parameters
+
+ Although a parameter must be supplied, it is ignored.
+ The value NULL can be used.
+
+ Return values
+
+ It can return an error EAGAIN to indicate that not
+ all condition variables were broadcast for some reason.
+ Otherwise, 0 is returned.
+
+ If run as a thread, the return value is returned
+ through pthread_join().
+
+ The return value should be cast to an integer.
+
+
+HANDLE
+pthread_getw32threadhandle_np(pthread_t thread);
+
+ Returns the win32 thread handle that the POSIX
+ thread "thread" is running as.
+
+ Applications can use the win32 handle to set
+ win32 specific attributes of the thread.
+
+DWORD
+pthread_getw32threadid_np (pthread_t thread)
+
+ Returns the win32 thread ID that the POSIX
+ thread "thread" is running as.
+
+ Only valid when the library is built where
+ ! defined (__MINGW32__) || defined (__MSVCRT__) || defined (__DMC__)
+ and otherwise returns 0.
+
+
+int
+pthread_mutexattr_setkind_np(pthread_mutexattr_t * attr, int kind)
+
+int
+pthread_mutexattr_getkind_np(pthread_mutexattr_t * attr, int *kind)
+
+ These two routines are included for Linux compatibility
+ and are direct equivalents to the standard routines
+ pthread_mutexattr_settype
+ pthread_mutexattr_gettype
+
+ pthread_mutexattr_setkind_np accepts the following
+ mutex kinds:
+ PTHREAD_MUTEX_FAST_NP
+ PTHREAD_MUTEX_ERRORCHECK_NP
+ PTHREAD_MUTEX_RECURSIVE_NP
+
+ These are really just equivalent to (respectively):
+ PTHREAD_MUTEX_NORMAL
+ PTHREAD_MUTEX_ERRORCHECK
+ PTHREAD_MUTEX_RECURSIVE
+
+int
+pthread_delay_np (const struct timespec *interval);
+
+ This routine causes a thread to delay execution for a specific period of time.
+ This period ends at the current time plus the specified interval. The routine
+ will not return before the end of the period is reached, but may return an
+ arbitrary amount of time after the period has gone by. This can be due to
+ system load, thread priorities, and system timer granularity.
+
+ Specifying an interval of zero (0) seconds and zero (0) nanoseconds is
+ allowed and can be used to force the thread to give up the processor or to
+ deliver a pending cancelation request.
+
+ This routine is a cancelation point.
+
+ The timespec structure contains the following two fields:
+
+ tv_sec is an integer number of seconds.
+ tv_nsec is an integer number of nanoseconds.
+
+ Return Values
+
+ If an error condition occurs, this routine returns an integer value
+ indicating the type of error. Possible return values are as follows:
+
+ 0 Successful completion.
+ [EINVAL] The value specified by interval is invalid.
+
+int
+pthread_num_processors_np (void)
+
+ This routine (found on HPUX systems) returns the number of processors
+ in the system. This implementation actually returns the number of
+ processors available to the process, which can be a lower number
+ than the system's number, depending on the process's affinity mask.
+
+BOOL
+pthread_win32_process_attach_np (void);
+
+BOOL
+pthread_win32_process_detach_np (void);
+
+BOOL
+pthread_win32_thread_attach_np (void);
+
+BOOL
+pthread_win32_thread_detach_np (void);
+
+ These functions contain the code normally run via dllMain
+ when the library is used as a dll but which need to be
+ called explicitly by an application when the library
+ is statically linked. As of version 2.9.0 of the library, static
+ builds using either MSC or GCC will call pthread_win32_process_*
+ automatically at application startup and exit respectively.
+
+ Otherwise, you will need to call pthread_win32_process_attach_np()
+ before you can call any pthread routines when statically linking.
+ You should call pthread_win32_process_detach_np() before
+ exiting your application to clean up.
+
+ pthread_win32_thread_attach_np() is currently a no-op, but
+ pthread_win32_thread_detach_np() is needed to clean up
+ the implicit pthread handle that is allocated to a Win32 thread if
+ it calls any pthreads routines. Call this routine when the
+ Win32 thread exits.
+
+ Threads created through pthread_create() do not need to call
+ pthread_win32_thread_detach_np().
+
+ These functions invariably return TRUE except for
+ pthread_win32_process_attach_np() which will return FALSE
+ if pthreads-win32 initialisation fails.
+
+int
+pthreadCancelableWait (HANDLE waitHandle);
+
+int
+pthreadCancelableTimedWait (HANDLE waitHandle, DWORD timeout);
+
+ These two functions provide hooks into the pthread_cancel
+ mechanism that will allow you to wait on a Windows handle
+ and make it a cancellation point. Both functions block
+ until either the given w32 handle is signaled, or
+ pthread_cancel has been called. It is implemented using
+ WaitForMultipleObjects on 'waitHandle' and a manually
+ reset w32 event used to implement pthread_cancel.
+
+
+Non-portable issues
+-------------------
+
+Thread priority
+
+ POSIX defines a single contiguous range of numbers that determine a
+ thread's priority. Win32 defines priority classes and priority
+ levels relative to these classes. Classes are simply priority base
+ levels that the defined priority levels are relative to such that,
+ changing a process's priority class will change the priority of all
+ of it's threads, while the threads retain the same relativity to each
+ other.
+
+ A Win32 system defines a single contiguous monotonic range of values
+ that define system priority levels, just like POSIX. However, Win32
+ restricts individual threads to a subset of this range on a
+ per-process basis.
+
+ The following table shows the base priority levels for combinations
+ of priority class and priority value in Win32.

+
+ Windows NT: Values -7, -6, -5, -4, -3, 3, 4, 5, and 6 are not supported.
+
+
+ As you can see, the real priority levels available to any individual
+ Win32 thread are non-contiguous.
+
+ An application using pthreads-win32 should not make assumptions about
+ the numbers used to represent thread priority levels, except that they
+ are monotonic between the values returned by sched_get_priority_min()
+ and sched_get_priority_max(). E.g. Windows 95, 98, NT, 2000, XP make
+ available a non-contiguous range of numbers between -15 and 15, while
+ at least one version of WinCE (3.0) defines the minimum priority
+ (THREAD_PRIORITY_LOWEST) as 5, and the maximum priority
+ (THREAD_PRIORITY_HIGHEST) as 1.
+
+ Internally, pthreads-win32 maps any priority levels between
+ THREAD_PRIORITY_IDLE and THREAD_PRIORITY_LOWEST to THREAD_PRIORITY_LOWEST,
+ or between THREAD_PRIORITY_TIME_CRITICAL and THREAD_PRIORITY_HIGHEST to
+ THREAD_PRIORITY_HIGHEST. Currently, this also applies to
+ REALTIME_PRIORITY_CLASSi even if levels -7, -6, -5, -4, -3, 3, 4, 5, and 6
+ are supported.
+
+ If it wishes, a Win32 application using pthreads-win32 can use the Win32
+ defined priority macros THREAD_PRIORITY_IDLE through
+ THREAD_PRIORITY_TIME_CRITICAL.

+
+----
+
+Some interesting news:
+
+I have been able to port pthread-win32 to Windows-CE,
+which uses a subset of the WIN32 API.
+
+Since we intend to keep using pthread-win32 for our
+Commercial WinCE developments, I would be very interested
+if WinCE support could be added to the main source tree
+of pthread-win32. Also, I would like to be credited
+for this port :-)
+
+Now, here is the story...
+
+The port was performed and tested on a Casio "Cassiopeia"
+PalmSize PC, which runs a MIP processor. The OS in the
+Casio is WinCE version 2.11, but I used VC++ 6.0 with
+the WinCE SDK for version 2.01.
+
+I used pthread-win32 to port a heavily multithreaded
+commercial application (real-time MPEG video player)
+from Linux to WinCE. I consider the changes that
+I have done to be quite well tested.
+
+Overall the modifications that we had to do are minor.
+
+The WinCE port were based on pthread-win32-snap-1999-05-30,
+but I am certain that they can be integrated very easiely
+to more recent versions of the source.
+
+I have attached the modified source code:
+pthread-win32-snap-1999-05-30-WinCE.
+
+All the changes do not affect the code compiled on non-WinCE
+environment, provided that the macros used for WinCE compilation
+are not used, of course!
+
+Overall description of the WinCE port:
+-------------------------------------
+
+Most of the changes had to be made in areas where
+pthread-win32 was relying on some standard-C librairies
+(e.g. _ftime, calloc, errno), which are not available
+on WinCE. We have changed the code to use native Win32
+API instead (or in some cases we made wrappers).
+
+The Win32 Semaphores are not available,
+so we had to re-implement Semaphores using mutexes
+and events.
+
+Limitations / known problems of the WinCE port:
+----------------------------------------------
+
+Not all the semaphore routines have been ported
+(semaphores are defined by Posix but are not part
+pf pthread). I have just done enough to make
+pthread routines (that rely internally on semaphores)
+work, like signal conditions.
+
+I noticed that the Win32 threads work slightly
+differently on WinCE. This may have some impact
+on some tricky parts of pthread-win32, but I have
+not really investigated. For example, on WinCE,
+the process is killed if the main thread falls off
+the bottom (or calls pthread_exit), regardless
+of the existence of any other detached thread.
+Microsoft manual indicates that this behavior is
+deffirent from that of Windows Threads for other
+Win32 platforms.
+
+
+Detailed descriptions of the changes and rationals:
+
+------------------------------------
+- use a new macro NEED_ERRNO.
+
+If defined, the code in errno.c that defines a reentrant errno
+is compiled, regardless of _MT and _REENTRANT.
+
+Rational: On WinCE, there is no support for <stdio.h>, <errno.h> or
+any other standard C library, i.e. even if _MT or _REENTRANT
+is defined, errno is not provided by any library. NEED_ERRNO
+must be set to compile for WinCE.
+
+------------------------------------
+- In implement.h, change #include <semaphore.h> to #include "semaphore.h".
+
+Rational: semaphore.h is provided in pthread-win32 and should not
+be searched in the systems standard include. would not compile.
+This change does not seem to create problems on "classic" win32
+(e.g. win95).
+
+------------------------------------
+- use a new macro NEED_CALLOC.
+
+If defined, some code in misc.c will provide a replacement
+for calloc, which is not available on Win32.
+
+
+------------------------------------
+- use a new macro NEED_CREATETHREAD.
+
+If defined, implement.h defines the macro _beginthreadex
+and _endthreadex.
+
+Rational: On WinCE, the wrappers _beginthreadex and _endthreadex
+do not exist. The native Win32 routines must be used.
+
+------------------------------------
+- in misc.c:
+
+#ifdef NEED_DUPLICATEHANDLE
+ /* DuplicateHandle does not exist on WinCE */
+ self->threadH = GetCurrentThread();
+#else
+ if( !DuplicateHandle(
+ GetCurrentProcess(),
+ GetCurrentThread(),
+ GetCurrentProcess(),
+ &self->threadH,
+ 0,
+ FALSE,
+ DUPLICATE_SAME_ACCESS ) )
+ {
+ free( self );
+ return (NULL);
+ }
+#endif
+
+Rational: On WinCE, DuplicateHandle does not exist. I could not understand
+why DuplicateHandle must be used. It seems to me that getting the current
+thread handle with GetCurrentThread() is sufficient, and it seems to work
+perfectly fine, so maybe DuplicateHandle was just plain useless to begin with ?
+
+------------------------------------
+- In private.c, added some code at the beginning of ptw32_processInitialize
+to detect the case of multiple calls to ptw32_processInitialize.
+
+Rational: In order to debug pthread-win32, it is easier to compile
+it as a regular library (it is not possible to debug DLL's on winCE).
+In that case, the application must call ptw32_rocessInitialize()
+explicitely, to initialize pthread-win32. It is safer in this circumstance
+to handle the case where ptw32_processInitialize() is called on
+an already initialized library:
+
+int
+ptw32_processInitialize (void)
+{
+ if (ptw32_processInitialized) {
+ /*
+ * ignore if already initialized. this is useful for
+ * programs that uses a non-dll pthread
+ * library. such programs must call ptw32_processInitialize() explicitely,
+ * since this initialization routine is automatically called only when
+ * the dll is loaded.
+ */
+ return TRUE;
+ }
+ ptw32_processInitialized = TRUE;
+ [...]
+}
+
+------------------------------------
+- in private.c, if macro NEED_FTIME is defined, add routines to
+convert timespec_to_filetime and filetime_to_timespec, and modified
+code that was using _ftime() to use Win32 API instead.
+
+Rational: _ftime is not available on WinCE. It is necessary to use
+the native Win32 time API instead.
+
+Note: the routine timespec_to_filetime is provided as a convenience and a mean
+to test that filetime_to_timespec works, but it is not used by the library.
+
+------------------------------------
+- in semaphore.c, if macro NEED_SEM is defined, add code for the routines
+_increase_semaphore and _decrease_semaphore, and modify significantly
+the implementation of the semaphores so that it does not use CreateSemaphore.
+
+Rational: CreateSemaphore is not available on WinCE. I had to re-implement
+semaphores using mutexes and Events.
+
+Note: Only the semaphore routines that are used by pthread are implemented
+(i.e. signal conditions rely on a subset of the semaphores routines, and
+this subset works). Some other semaphore routines (e.g. sem_trywait) are
+not yet supported on my WinCE port (and since I don't need them, I am not
+planning to do anything about them).
+
+------------------------------------
+- in tsd.c, changed the code that defines TLS_OUT_OF_INDEXES
+
+/* TLS_OUT_OF_INDEXES not defined on WinCE */
+#ifndef TLS_OUT_OF_INDEXES
+#define TLS_OUT_OF_INDEXES 0xffffffff
+#endif
+
+Rational: TLS_OUT_OF_INDEXES is not defined in any standard include file
+on WinCE.
+
+------------------------------------
+- added file need_errno.h
+
+Rational: On WinCE, there is no errno.h file. need_errno.h is just a
+copy of windows version of errno.h, with minor modifications due to the fact
+that some of the error codes are defined by the WinCE socket library.
+In pthread.h, if NEED_ERRNO is defined, the file need_errno.h is
+included (instead of <errno.h>).

This avoids the need for a - * dedicated lock for each association, which not only consumes - * more handles but requires that: before the lock handle can - * be released - both the key must be deleted and the thread - * must have called the destructor. The two-lock arrangement - * allows the resources to be freed as soon as either thread or - * key is concluded. - * - * To avoid deadlock: whenever both locks are required, the key - * and thread locks are always acquired in the order: key lock - * then thread lock. An exception to this exists when a thread - * calls the destructors, however this is done carefully to - * avoid deadlock. - * - * An association is created when a thread first calls - * pthread_setspecific() on a key that has a specified - * destructor. - * - * An association is destroyed either immediately after the - * thread calls the key destructor function on thread exit, or - * when the key is deleted. - * - * Attributes: - * thread - * reference to the thread that owns the - * association. This is actually the pointer to the - * thread struct itself. Since the association is - * destroyed before the thread exits, this can never - * point to a different logical thread to the one that - * created the assoc, i.e. after thread struct reuse. - * - * key - * reference to the key that owns the association. - * - * nextKey - * The pthread_t->keys attribute is the head of a - * chain of associations that runs through the nextKey - * link. This chain provides the 1 to many relationship - * between a pthread_t and all pthread_key_t on which - * it called pthread_setspecific. - * - * prevKey - * Similarly. - * - * nextThread - * The pthread_key_t->threads attribute is the head of - * a chain of assoctiations that runs through the - * nextThreads link. This chain provides the 1 to many - * relationship between a pthread_key_t and all the - * PThreads that have called pthread_setspecific for - * this pthread_key_t. - * - * prevThread - * Similarly. - * - * Notes: - * 1) As soon as either the key or the thread is no longer - * referencing the association, it can be destroyed. The - * association will be removed from both chains. - * - * 2) Under WIN32, an association is only created by - * pthread_setspecific if the user provided a - * destroyRoutine when they created the key. - * - * - */ - ptw32_thread_t * thread; - pthread_key_t key; - ThreadKeyAssoc *nextKey; - ThreadKeyAssoc *nextThread; - ThreadKeyAssoc *prevKey; - ThreadKeyAssoc *prevThread; -}; - - -#ifdef __CLEANUP_SEH -/* - * -------------------------------------------------------------- - * MAKE_SOFTWARE_EXCEPTION - * This macro constructs a software exception code following - * the same format as the standard Win32 error codes as defined - * in WINERROR.H - * Values are 32 bit values layed out as follows: - * - * 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 - * +---+-+-+-----------------------+-------------------------------+ - * |Sev|C|R| Facility | Code | - * +---+-+-+-----------------------+-------------------------------+ - * - * Severity Values: - */ -#define SE_SUCCESS 0x00 -#define SE_INFORMATION 0x01 -#define SE_WARNING 0x02 -#define SE_ERROR 0x03 - -#define MAKE_SOFTWARE_EXCEPTION( _severity, _facility, _exception ) \ -( (DWORD) ( ( (_severity) << 30 ) | /* Severity code */ \ - ( 1 << 29 ) | /* MS=0, User=1 */ \ - ( 0 << 28 ) | /* Reserved */ \ - ( (_facility) << 16 ) | /* Facility Code */ \ - ( (_exception) << 0 ) /* Exception Code */ \ - ) ) - -/* - * We choose one specific Facility/Error code combination to - * identify our software exceptions vs. WIN32 exceptions. - * We store our actual component and error code within - * the optional information array. - */ -#define EXCEPTION_PTW32_SERVICES \ - MAKE_SOFTWARE_EXCEPTION( SE_ERROR, \ - PTW32_SERVICES_FACILITY, \ - PTW32_SERVICES_ERROR ) - -#define PTW32_SERVICES_FACILITY 0xBAD -#define PTW32_SERVICES_ERROR 0xDEED - -#endif /* __CLEANUP_SEH */ - -/* - * Services available through EXCEPTION_PTW32_SERVICES - * and also used [as parameters to ptw32_throw()] as - * generic exception selectors. - */ - -#define PTW32_EPS_EXIT (1) -#define PTW32_EPS_CANCEL (2) - - -/* Useful macros */ -#define PTW32_MAX(a,b) ((a)<(b)?(b):(a)) -#define PTW32_MIN(a,b) ((a)>(b)?(b):(a)) - - -/* Declared in global.c */ -extern PTW32_INTERLOCKED_LONG (WINAPI * - ptw32_interlocked_compare_exchange) - (PTW32_INTERLOCKED_LPLONG, PTW32_INTERLOCKED_LONG, PTW32_INTERLOCKED_LONG); - -/* Declared in pthread_cancel.c */ -extern DWORD (*ptw32_register_cancelation) (PAPCFUNC, HANDLE, DWORD); - -/* Thread Reuse stack bottom marker.

+ * Purpose:
+ * This structure creates an association between a thread and a key.
+ * It is used to implement the implicit invocation of a user defined
+ * destroy routine for thread specific data registered by a user upon
+ * exiting a thread.
+ *
+ * Graphically, the arrangement is as follows, where:
+ *
+ * K - Key with destructor
+ * (head of chain is key->threads)
+ * T - Thread that has called pthread_setspecific(Kn)
+ * (head of chain is thread->keys)
+ * A - Association. Each association is a node at the
+ * intersection of two doubly-linked lists.
+ *
+ * T1 T2 T3
+ * | | |
+ * | | |
+ * K1 -----+-----A-----A----->
+ * | | |
+ * | | |
+ * K2 -----A-----A-----+----->
+ * | | |
+ * | | |
+ * K3 -----A-----+-----A----->
+ * | | |
+ * | | |
+ * V V V
+ *
+ * Access to the association is guarded by two locks: the key's
+ * general lock (guarding the row) and the thread's general
+ * lock (guarding the column). This avoids the need for a
+ * dedicated lock for each association, which not only consumes
+ * more handles but requires that the lock resources persist
+ * until both the key is deleted and the thread has called the
+ * destructor. The two-lock arrangement allows those resources
+ * to be freed as soon as either thread or key is concluded.
+ *
+ * To avoid deadlock, whenever both locks are required both the
+ * key and thread locks are acquired consistently in the order
+ * "key lock then thread lock". An exception to this exists
+ * when a thread calls the destructors, however, this is done
+ * carefully (but inelegantly) to avoid deadlock.
+ *
+ * An association is created when a thread first calls
+ * pthread_setspecific() on a key that has a specified
+ * destructor.
+ *
+ * An association is destroyed either immediately after the
+ * thread calls the key destructor function on thread exit, or
+ * when the key is deleted.
+ *
+ * Attributes:
+ * thread
+ * reference to the thread that owns the
+ * association. This is actually the pointer to the
+ * thread struct itself. Since the association is
+ * destroyed before the thread exits, this can never
+ * point to a different logical thread to the one that
+ * created the assoc, i.e. after thread struct reuse.
+ *
+ * key
+ * reference to the key that owns the association.
+ *
+ * nextKey
+ * The pthread_t->keys attribute is the head of a
+ * chain of associations that runs through the nextKey
+ * link. This chain provides the 1 to many relationship
+ * between a pthread_t and all pthread_key_t on which
+ * it called pthread_setspecific.
+ *
+ * prevKey
+ * Similarly.
+ *
+ * nextThread
+ * The pthread_key_t->threads attribute is the head of
+ * a chain of associations that runs through the
+ * nextThreads link. This chain provides the 1 to many
+ * relationship between a pthread_key_t and all the
+ * PThreads that have called pthread_setspecific for
+ * this pthread_key_t.
+ *
+ * prevThread
+ * Similarly.
+ *
+ * Notes:
+ * 1) As soon as either the key or the thread is no longer
+ * referencing the association, it can be destroyed. The
+ * association will be removed from both chains.
+ *
+ * 2) Under WIN32, an association is only created by
+ * pthread_setspecific if the user provided a
+ * destroyRoutine when they created the key.

+<P>The <B>pthread_barrier_wait</B> function shall synchronize
+participating threads at the barrier referenced by <I>barrier</I>.
+The calling thread shall block until the required number of threads
+have called <B>pthread_barrier_wait</B> specifying the barrier.
+</P>
+<P>When the required number of threads have called
+<B>pthread_barrier_wait</B> specifying the barrier, the constant
+<B>PTHREAD_BARRIER_SERIAL_THREAD</B> shall be returned to one
+unspecified thread and zero shall be returned to each of the
+remaining threads. At this point, the barrier shall be reset to the
+state it had as a result of the most recent <A HREF="pthread_barrier_init.html"><B>pthread_barrier_init</B>(3)</A>
+function that referenced it.
+</P>
+<P>The constant <B>PTHREAD_BARRIER_SERIAL_THREAD</B> is defined in
+<I><pthread.h></I> and its value shall be distinct from any
+other value returned by <B>pthread_barrier_wait</B> .
+</P>
+<P>The results are undefined if this function is called with an
+uninitialized barrier.
+</P>
+<P>If a signal is delivered to a thread blocked on a barrier, upon
+return from the signal handler the thread shall resume waiting at the
+barrier if the barrier wait has not completed (that is, if the
+required number of threads have not arrived at the barrier during the
+execution of the signal handler); otherwise, the thread shall
+continue as normal from the completed barrier wait. Until the thread
+in the signal handler returns from it, it is unspecified whether
+other threads may proceed past the barrier once they have all reached
+it.
+</P>
+<P>A thread that has blocked on a barrier shall not prevent any
+unblocked thread that is eligible to use the same processing
+resources from eventually making forward progress in its execution.
+Eligibility for processing resources shall be determined by the
+scheduling policy.
+</P>
+<H2><A HREF="#toc3" NAME="sect3">Return Value</A></H2>
+<P>Upon successful completion, the <B>pthread_barrier_wait</B>
+function shall return <B>PTHREAD_BARRIER_SERIAL_THREAD</B> for a
+single (arbitrary) thread synchronized at the barrier and zero for
+each of the other threads. Otherwise, an error number shall be
+returned to indicate the error.

+<P>These functions contain the code normally run via <b>dllMain</b>
+when the library is used as a dll but which need to be called
+explicitly by an application when the library is statically linked. As of version 2.9.0, the static library built using either MSC or GCC includes RT hooks which will call the pthread_win32_process_*_np routines automatically on start/exit of the application.</P>
+<P>You will need to call <B>pthread_win32_process_attach_np</B>
+before you can call any pthread routines when statically linking. You
+should call <B>pthread_win32_process_detach_np</B> before exiting
+your application to clean up.</P>
+<P><B>pthread_win32_thread_attach_np</B> is currently a no-op, but
+<B>pthread_win32_thread_detach_np</B> is needed to clean up the
+implicit pthread handle that is allocated to a Win32 thread if it
+calls certain pthreads routines. Call this routine when the Win32
+thread exits.</P>
+<P>These functions invariably return TRUE except for
+<B>pthread_win32_process_attach_np</B> which will return FALSE if
+pthreads-w32 initialisation fails.</P>

+ * -------------------------------------------------------------
+ *
+ *
+ * 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 <rpj@callisto.canberra.edu.au>
+ *
+ * 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 <unistd.h>, 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.
+ * pthread_mutexattr_getprotocol +
+ * pthread_mutexattr_setprotocol +
+ *
+ * _POSIX_THREAD_PRIO_PROTECT (== -1)
+ * If == 200112L, you can create priority ceiling mutexes
+ * Indicates the availability of:
+ * pthread_mutex_getprioceiling
+ * pthread_mutex_setprioceiling
+ * pthread_mutexattr_getprioceiling
+ * pthread_mutexattr_getprotocol +
+ * pthread_mutexattr_setprioceiling
+ * 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
+ * of:
+ * pthread_mutexattr_getpshared
+ * pthread_mutexattr_setpshared
+ * pthread_condattr_getpshared
+ * 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
+ * 'protect' protocol, based upon these macro
+ * settings.

+ *
+ * DESCRIPTION
+ * This function destroys a condition variable.
+ *
+ * NOTES:
+ * 1) A condition variable can be destroyed
+ * immediately after all the threads that
+ * are blocked on it are awakened. e.g.
+ *
+ * struct list {
+ * pthread_mutex_t lm;
+ * ...
+ * }
+ *
+ * struct elt {
+ * key k;
+ * int busy;
+ * pthread_cond_t notbusy;
+ * ...
+ * }
+ *
+ *
+ * struct elt *
+ * list_find(struct list *lp, key k)
+ * {
+ * struct elt *ep;
+ *
+ * pthread_mutex_lock(&lp->lm);
+ * while ((ep = find_elt(l,k) != NULL) && ep->busy)
+ * pthread_cond_wait(&ep->notbusy, &lp->lm);
+ * if (ep != NULL)
+ * ep->busy = 1;
+ * pthread_mutex_unlock(&lp->lm);
+ * return(ep);
+ * }
+ *
+ * delete_elt(struct list *lp, struct elt *ep)
+ * {
+ * pthread_mutex_lock(&lp->lm);
+ * assert(ep->busy);
+ * ... remove ep from list ...
+ * ep->busy = 0;
+ * (A) pthread_cond_broadcast(&ep->notbusy);
+ * pthread_mutex_unlock(&lp->lm);
+ * (B) pthread_cond_destroy(&rp->notbusy);
+ * free(ep);
+ * }
+ *
+ * In this example, the condition variable
+ * and its list element may be freed (line B)
+ * immediately after all threads waiting for
+ * it are awakened (line A), since the mutex
+ * and the code ensure that no other thread
+ * can touch the element to be deleted.
+ *
+ * RESULTS
+ * 0 successfully released condition variable,
+ * EINVAL 'cond' is invalid,
+ * EBUSY 'cond' is in use,

+/*
+ * 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);
