This was obviated - by user space sema acquisition in sem_wait() and sem_timedwait(), - which are also cancelation points.

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 - - * 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 - - * 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 - - * 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.

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 - - * 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 - - * 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 - - * 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 - - * FAQ: Update Answer 6 re getting a fully working - Mingw32 built library. - -2000-10-10 Steven Reddie - - * misc.c (pthread_self): Restore Win32 "last error" - cleared by TlsGetValue() call in - pthread_getspecific() - -2000-09-20 Arthur Kantor - - * 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 - - * 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.

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 - - * 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 - - * private.c (ptw32_sem_timedwait): Move from semaphore.c. - - * semaphore.c : Remove redundant #includes. - (ptw32_sem_timedwait): Move to private.c. - (sem_wait): Add missing abstime arg to pthreadCancelableWait() call. - -Fri Jan 15 23:38:05 1999 Ross Johnson - - * condvar.c (cond_timedwait): Remove comment. - -Fri Jan 15 15:41:28 1999 Ross Johnson - - * pthread.h: Add new 'abstime' arg to pthreadCancelableWait() - prototype. - - * condvar.c (cond_timedwait): New generalised function called by - both pthread_cond_wait() and pthread_cond_timedwait(). This is - essentially pthread_cond_wait() renamed and modified to add the - 'abstime' arg and call the new ptw32_sem_timedwait() instead of - sem_wait(). - (pthread_cond_wait): Now just calls the internal static - function cond_timedwait() with an INFINITE wait. - (pthread_cond_timedwait): Now implemented. Calls the internal - static function cond_timedwait(). - - * implement.h (ptw32_sem_timedwait): New internal function - prototype. - - * misc.c (pthreadCancelableWait): Added new 'abstime' argument - to allow shorter than INFINITE wait. - - * semaphore.c (ptw32_sem_timedwait): New function for internal - use. This is essentially sem_wait() modified to add the - 'abstime' arg and call the modified (see above) - pthreadCancelableWait(). - -Thu Jan 14 14:27:13 1999 Ross Johnson - - * cleanup.c: Correct _cplusplus to __cplusplus wherever used. - - * Makefile.in: Add CC=g++ and add -fhandle-exceptions to CFLAGS. - The derived Makefile will compile all units of the package as C++ - so that those which include try/catch exception handling should work - properly. The package should compile ok if CC=gcc, however, exception - handling will not be included and thus thread cancellation, for - example, will not work. - - * cleanup.c (ptw32_pop_cleanup): Add #warning to compile this - file as C++ if using a cygwin32 environment. Perhaps the whole package - should be compiled using g++ under cygwin. - - * private.c (ptw32_threadStart): Change #error directive - into #warning and bracket for __CYGWIN__ and derivative compilers. - -Wed Jan 13 09:34:52 1999 Ross Johnson - - * build.bat: Delete old binaries before compiling/linking. - -Tue Jan 12 09:58:38 1999 Tor Lillqvist - - * dll.c: The Microsoft compiler pragmas probably are more - appropriately protected by _MSC_VER than by _WIN32. - - * pthread.h: Define ETIMEDOUT.

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.

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

The POSIX thread ID will be created -automatically by any POSIX routines that need a POSIX handle (unless the routine -needs a pthread_t as a parameter of course). A Win32 thread can discover it's own -POSIX thread ID by calling pthread_self(), which will create the handle if -necessary and return the pthread_t value. - -New tests ---------- -Test the above new feature. - - -SNAPSHOT 2003-08-19 -------------------- - -This snapshot fixes some accidental corruption to new test case sources. -There are no changes to the library source code. - - -SNAPSHOT 2003-08-15 -------------------- - -Bug fixes ---------- - -* pthread.dsp now uses correct compile flags (/MD). -- Viv - -* pthread_win32_process_detach_np() fixed memory leak. -- Steven Reddie - -* pthread_mutex_destroy() fixed incorrect return code. -- Nicolas Barry - -* pthread_spin_destroy() fixed memory leak. -- Piet van Bruggen - -* Various changes to tighten arg checking, and to work with later versions of -MinGW32 and MsysDTK. - -* pthread_getschedparam() etc, fixed dangerous thread validity checking. -- Nicolas Barry - -* POSIX thread handles are now reused and their memory is not freed on thread exit. -This allows for stronger thread validity checking. - -New standard routine --------------------- - -* pthread_kill() added to provide thread validity checking to applications. -It does not accept any non zero values for the signal arg. - -New test cases --------------- - -* New test cases to confirm validity checking, pthread_kill(), and thread reuse. - - -SNAPSHOT 2003-05-10 -------------------- - -Bug fixes ---------- - -* pthread_mutex_trylock() now returns correct error values. -pthread_mutex_destroy() will no longer destroy a recursively locked mutex. -pthread_mutex_lock() is no longer inadvertantly behaving as a cancelation point. -- Thomas Pfaff - -* pthread_mutex_timedlock() no longer occasionally sets incorrect mutex -ownership, causing deadlocks in some applications. -- Robert Strycek and Alexander Terekhov - - -SNAPSHOT 2002-11-04 -------------------- - -Bug fixes ---------- - -* sem_getvalue() now returns the correct value under Win NT and WinCE. -- Rob Fanner - -* sem_timedwait() now uses tighter checks for unreasonable -abstime values - that would result in unexpected timeout values. - -* ptw32_cond_wait_cleanup() no longer mysteriously consumes -CV signals but may produce more spurious wakeups.

(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.

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). +- + +* 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. + + +SNAPSHOT 2004-11-03 +------------------- + +DLLs produced from this snapshot cannot be used with older applications without +recompiling the application, due to a change to pthread_t to provide unique POSIX +thread IDs. + +Although this snapshot passes the extended test suite, many of the changes are +fairly major, and some applications may show different behaviour than previously, +so adopt with care. Hopefully, any changed behaviour will be due to the library +being better at it's job, not worse. + +Bug fixes +--------- + +* pthread_create() no longer accepts NULL as the thread reference arg. +A segfault (memory access fault) will result, and no thread will be +created. + +* pthread_barrier_wait() no longer acts as a cancelation point. + +* Fix potential race condition in pthread_once() +- Tristan Savatier + +* Changes to pthread_cond_destroy() exposed some coding weaknesses in several +test suite mini-apps because pthread_cond_destroy() now returns EBUSY if the CV +is still in use. + +New features +------------ + +* Added for compatibility: +PTHREAD_RECURSIVE_MUTEX_INITIALIZER, +PTHREAD_ERRORCHECK_MUTEX_INITIALIZER, +PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP, +PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP + +* Initial support for Digital Mars compiler +- Anuj Goyal + +* Faster Mutexes. These have been been rewritten following a model provided by +Alexander Terekhov that reduces kernel space checks, and eliminates some additional +critical sections used to manage a race between timedlock expiration and unlock. +Please be aware that the new mutexes do not enforce strict absolute FIFO scheduling +of mutexes, however any out-of-order lock acquisition should be very rare. + +* Faster semaphores. Following a similar model to mutexes above, these have been +rewritten to use preliminary users space checks. + +* sem_getvalue() now returns the number of waiters. + +* The POSIX thread ID now has much stronger uniqueness characteristics. The library +garrantees not to reuse the same thread ID for at least 2^(wordsize) thread +destruction/creation cycles. + +New tests +--------- + +* semaphore4.c: Tests cancelation of the new sem_wait(). + +* semaphore4t.c: Likewise for sem_timedwait(). + +* rwlock8.c: Tests and times the slow execution paths of r/w locks, and the CVs, +mutexes, and semaphores that they're built on. + + +SNAPSHOT 2004-05-16 +------------------- + +Attempt to add Watcom to the list of compilers that can build the library. +This failed in the end due to it's non-thread-aware errno. The library +builds but the test suite fails. See README.Watcom for more details. + +Bug fixes +--------- +* Bug and memory leak in sem_init() +- Alex Blanco + +* ptw32_getprocessors() now returns CPU count of 1 for WinCE. +- James Ewing + +* pthread_cond_wait() could be canceled at a point where it should not +be cancelable. Fixed. +- Alexander Terekhov + +* sem_timedwait() had an incorrect timeout calculation. +- Philippe Di Cristo + +* Fix a memory leak left behind after threads are destroyed. +- P. van Bruggen + +New features +------------ +* Ported to AMD64. +- Makoto Kato + +* True pre-emptive asynchronous cancelation of threads. This is optional +and requires that Panagiotis E. Hadjidoukas's QueueUserAPCEx package be +installed. This package is included in the pthreads-win32 self-unpacking +Zip archive starting from this snapshot. See the README.txt file inside +the package for installation details. + +Note: If you don't use async cancelation in your application, or don't need +to cancel threads that are blocked on system resources such as network I/O, +then the default non-preemptive async cancelation is probably good enough. +However, pthreads-win32 auto-detects the availability of these components +at run-time, so you don't need to rebuild the library from source if you +change your mind later. + +All of the advice available in books and elsewhere on the undesirability +of using async cancelation in any application still stands, but this +feature is a welcome addition with respect to the library's conformance to +the POSIX standard. + +SNAPSHOT 2003-09-18 +------------------- + +Cleanup of thread priority management. In particular, setting of thread +priority now attempts to map invalid Win32 values within the range returned +by sched_get_priority_min/max() to useful values. See README.NONPORTABLE +under "Thread priority". + +Bug fixes +--------- +* pthread_getschedparam() now returns the priority given by the most recent +call to pthread_setschedparam() or established by pthread_create(), as +required by the standard. Previously, pthread_getschedparam() incorrectly +returned the running thread priority at the time of the call, which may have +been adjusted or temporarily promoted/demoted. + +* sched_get_priority_min() and sched_get_priority_max() now return -1 on error +and set errno. Previously, they incorrectly returned the error value directly. + + +SNAPSHOT 2003-09-04 +------------------- + +Bug fixes +--------- +* ptw32_cancelableWait() now allows cancelation of waiting implicit POSIX +threads. + +New test +-------- +* cancel8.c tests cancelation of Win32 threads waiting at a POSIX cancelation +point. + + +SNAPSHOT 2003-09-03 +------------------- + +Bug fixes +--------- +* pthread_self() would free the newly created implicit POSIX thread handle if +DuplicateHandle failed instead of recycle it (very unlikely). + +* pthread_exit() was neither freeing nor recycling the POSIX thread struct +for implicit POSIX threads. + +New feature - Cancelation of/by Win32 (non-POSIX) threads +--------------------------------------------------------- +Since John Bossom's original implementation, the library has allowed non-POSIX +initialised threads (Win32 threads) to call pthreads-win32 routines and +therefore interact with POSIX threads. This is done by creating an on-the-fly +POSIX thread ID for the Win32 thread that, once created, allows fully +reciprical interaction. This did not extend to thread cancelation (async or +deferred). Now it does. + +Any thread can be canceled by any other thread (Win32 or POSIX) if the former +thread's POSIX pthread_t value is known. It's TSD destructors and POSIX +cleanup handlers will be run before the thread exits with an exit code of +PTHREAD_CANCELED (retrieved with GetExitCodeThread()). + +This allows a Win32 thread to, for example, call POSIX CV routines in the same way +that POSIX threads would/should, with pthread_cond_wait() cancelability and +cleanup handlers (pthread_cond_wait() is a POSIX cancelation point). + +By adding cancelation, Win32 threads should now be able to call all POSIX +threads routines that make sense including semaphores, mutexes, condition +variables, read/write locks, barriers, spinlocks, tsd, cleanup push/pop, +cancelation, pthread_exit, scheduling, etc. + +Note that these on-the-fly 'implicit' POSIX thread IDs are initialised as detached +(not joinable) with deferred cancelation type. The POSIX thread ID will be created +automatically by any POSIX routines that need a POSIX handle (unless the routine +needs a pthread_t as a parameter of course). A Win32 thread can discover it's own +POSIX thread ID by calling pthread_self(), which will create the handle if +necessary and return the pthread_t value. + +New tests +--------- +Test the above new feature. + + +SNAPSHOT 2003-08-19 +------------------- + +This snapshot fixes some accidental corruption to new test case sources. +There are no changes to the library source code. + + +SNAPSHOT 2003-08-15 +------------------- + +Bug fixes +--------- + +* pthread.dsp now uses correct compile flags (/MD). +- Viv + +* pthread_win32_process_detach_np() fixed memory leak. +- Steven Reddie + +* pthread_mutex_destroy() fixed incorrect return code. +- Nicolas Barry + +* pthread_spin_destroy() fixed memory leak. +- Piet van Bruggen + +* Various changes to tighten arg checking, and to work with later versions of +MinGW32 and MsysDTK. + +* pthread_getschedparam() etc, fixed dangerous thread validity checking. +- Nicolas Barry + +* POSIX thread handles are now reused and their memory is not freed on thread exit. +This allows for stronger thread validity checking. + +New standard routine +-------------------- + +* pthread_kill() added to provide thread validity checking to applications. +It does not accept any non zero values for the signal arg. + +New test cases +-------------- + +* New test cases to confirm validity checking, pthread_kill(), and thread reuse. + + +SNAPSHOT 2003-05-10 +------------------- + +Bug fixes +--------- + +* pthread_mutex_trylock() now returns correct error values. +pthread_mutex_destroy() will no longer destroy a recursively locked mutex. +pthread_mutex_lock() is no longer inadvertantly behaving as a cancelation point. +- Thomas Pfaff + +* pthread_mutex_timedlock() no longer occasionally sets incorrect mutex +ownership, causing deadlocks in some applications. +- Robert Strycek and Alexander Terekhov + + +SNAPSHOT 2002-11-04 +------------------- + +Bug fixes +--------- + +* sem_getvalue() now returns the correct value under Win NT and WinCE. +- Rob Fanner + +* sem_timedwait() now uses tighter checks for unreasonable +abstime values - that would result in unexpected timeout values. + +* ptw32_cond_wait_cleanup() no longer mysteriously consumes +CV signals but may produce more spurious wakeups. It is believed +that the sem_timedwait() call is consuming a CV signal that it +shouldn't. +- Alexander Terekhov + +* Fixed a memory leak in ptw32_threadDestroy() for implicit threads. + +* Fixed potential for deadlock in pthread_cond_destroy(). +A deadlock could occur for statically declared CVs (PTHREAD_COND_INITIALIZER), +when one thread is attempting to destroy the condition variable while another +is attempting to dynamically initialize it. +- Michael Johnson + + +SNAPSHOT 2002-03-02 +------------------- + +Cleanup code default style. (IMPORTANT) +---------------------------------------------------------------------- +Previously, if not defined, the cleanup style was determined automatically +from the compiler/language, and one of the following was defined accordingly: + + __CLEANUP_SEH MSVC only + __CLEANUP_CXX C++, including MSVC++, GNU G++ + __CLEANUP_C C, including GNU GCC, not MSVC + +These defines determine the style of cleanup (see pthread.h) and, +most importantly, the way that cancelation and thread exit (via +pthread_exit) is performed (see the routine ptw32_throw() in private.c). + +In short, the exceptions versions of the library throw an exception +when a thread is canceled or exits (via pthread_exit()), which is +caught by a handler in the thread startup routine, so that the +the correct stack unwinding occurs regardless of where the thread +is when it's canceled or exits via pthread_exit(). + +In this and future snapshots, unless the build explicitly defines (e.g. +via a compiler option) __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then +the build NOW always defaults to __CLEANUP_C style cleanup. This style +uses setjmp/longjmp in the cancelation and pthread_exit implementations, +and therefore won't do stack unwinding even when linked to applications +that have it (e.g. C++ apps). This is for consistency with most +current commercial Unix POSIX threads implementations. Compaq's TRU64 +may be an exception (no pun intended) and possible future trend. + +Although it was not clearly documented before, it is still necessary to +build your application using the same __CLEANUP_* define as was +used for the version of the library that you link with, so that the +correct parts of pthread.h are included. That is, the possible +defines require the following library versions: + + __CLEANUP_SEH pthreadVSE.dll + __CLEANUP_CXX pthreadVCE.dll or pthreadGCE.dll + __CLEANUP_C pthreadVC.dll or pthreadGC.dll + +E.g. regardless of whether your app is C or C++, if you link with +pthreadVC.lib or libpthreadGC.a, then you must define __CLEANUP_C. + + +THE POINT OF ALL THIS IS: if you have not been defining one of these +explicitly, then the defaults as described at the top of this +section were being used. + +THIS NOW CHANGES, as has been explained above, but to try to make this +clearer here's an example: + +If you were building your application with MSVC++ i.e. using C++ +exceptions and not explicitly defining one of __CLEANUP_*, then +__CLEANUP_C++ was automatically defined for you in pthread.h. +You should have been linking with pthreadVCE.dll, which does +stack unwinding. + +If you now build your application as you had before, pthread.h will now +automatically set __CLEANUP_C as the default style, and you will need to +link with pthreadVC.dll. Stack unwinding will now NOT occur when a thread +is canceled, or the thread calls pthread_exit(). + +Your application will now most likely behave differently to previous +versions, and in non-obvious ways. Most likely is that locally +instantiated objects may not be destroyed or cleaned up after a thread +is canceled. + +If you want the same behaviour as before, then you must now define +__CLEANUP_C++ explicitly using a compiler option and link with +pthreadVCE.dll as you did before. + + +WHY ARE WE MAKING THE DEFAULT STYLE LESS EXCEPTION-FRIENDLY? +Because no commercial Unix POSIX threads implementation allows you to +choose to have stack unwinding. Therefore, providing it in pthread-win32 +as a default is dangerous. We still provide the choice but unless +you consciously choose to do otherwise, your pthreads applications will +now run or crash in similar ways irrespective of the threads platform +you use. Or at least this is the hope. + + +WHY NOT REMOVE THE EXCEPTIONS VERSIONS OF THE LIBRARY ALTOGETHER? +There are a few reasons: +- because there are well respected POSIX threads people who believe + that POSIX threads implementations should be exceptions aware and + do the expected thing in that context. (There are equally respected + people who believe it should not be easily accessible, if it's there + at all, for unconditional conformity to other implementations.) +- because pthreads-win32 is one of the few implementations that has + the choice, perhaps the only freely available one, and so offers + a laboratory to people who may want to explore the effects; +- although the code will always be around somewhere for anyone who + wants it, once it's removed from the current version it will not be + nearly as visible to people who may have a use for it. + + +Source module splitting +----------------------- +In order to enable smaller image sizes to be generated +for applications that link statically with the library, +most routines have been separated out into individual +source code files. + +This is being done in such a way as to be backward compatible. +The old source files are reused to congregate the individual +routine files into larger translation units (via a bunch of +# includes) so that the compiler can still optimise wherever +possible, e.g. through inlining, which can only be done +within the same translation unit. + +It is also possible to build the entire library by compiling +the single file named "pthread.c", which just #includes all +the secondary congregation source files. The compiler +may be able to use this to do more inlining of routines. + +Although the GNU compiler is able to produce libraries with +the necessary separation (the -ffunction-segments switch), +AFAIK, the MSVC and other compilers don't have this feature. + +Finally, since I use makefiles and command-line compilation, +I don't know what havoc this reorganisation may wreak amongst +IDE project file users. You should be able to continue +using your existing project files without modification. + + +New non-portable functions +-------------------------- +pthread_num_processors_np(): + Returns the number of processors in the system that are + available to the process, as determined from the processor + affinity mask. + +pthread_timechange_handler_np(): + To improve tolerance against operator or time service initiated + system clock changes. + + This routine can be called by an application when it + receives a WM_TIMECHANGE message from the system.

The version parameter is two + 32-bit integers, defined by four 16-bit integers. + For more information about version, see the + FILEVERSION description. + FILEFLAGSMASK + fileflagsmask Bits in the FILEFLAGS statement are valid. If a bit + is set, the corresponding bit in FILEFLAGS is valid. + FILEFLAGSfileflags Attributes of the file. The fileflags parameter must + be the combination of all the file flags that are + valid at compile time. For 16-bit Windows, this + value is 0x3f. + FILEOSfileos Operating system for which this file was designed. + The fileos parameter can be one of the operating + system values given in the Remarks section. + FILETYPEfiletype General type of file. The filetype parameter can be + one of the file type values listed in the Remarks + section. + FILESUBTYPE + subtype Function of the file. The subtype parameter is zero + unless the type parameter in the FILETYPE statement + is VFT_DRV, VFT_FONT, or VFT_VXD. For a list of file + subtype values, see the Remarks section. + +block-statement + Specifies one or more version-information blocks. A block can contain + string information or variable information.
