- PTHREADS-WIN32 RELEASE 2.9.0 (2007-??-??)
- -----------------------------------------
- Web Site: http://sources.redhat.com/pthreads-win32/
- FTP Site: ftp://sources.redhat.com/pub/pthreads-win32
- Maintainer: Ross Johnson <rpj@callisto.canberra.edu.au>
-
-
-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:
-
- http://sources.redhat.com/pthreads-win32
-
-As much as possible, the ChangeLog file acknowledges contributions to the
-code base in more detail.

+ PTHREADS-WIN32 RELEASE 2.9.0 (2007-??-??)
+ -----------------------------------------
+ Web Site: http://sources.redhat.com/pthreads-win32/
+ FTP Site: ftp://sources.redhat.com/pub/pthreads-win32
+ Maintainer: Ross Johnson <rpj@callisto.canberra.edu.au>
+
+
+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:
+
+ http://sources.redhat.com/pthreads-win32
+
+As much as possible, the ChangeLog file acknowledges contributions to the
+code base in more detail.

-2006-01-25 Prashant Thakre <prashant.thakre at gmail.com>
-
- * pthread_cancel.c: Added _M_IA64 register context support.
-
-2005-05-13 Ross Johnson <ross at callisto.canberra.edu.au>
-
- * pthread_kill.c (pthread_kill): Remove check for Win32 thread
- priority (to confirm HANDLE validity). Useless since thread HANDLEs
- a not recycle-unique.
-
-2005-05-30 Vladimir Kliatchko <vladimir at kliatchko.com>
-
- * 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
- init_routine thread is cancelled yet still release all waiters when
- done. Simplify once_control state checks to improve efficiency
- further.
-
-2005-05-24 Mikael Magnusson <mikaelmagnusson at glocalnet.net>
-
- * GNUmakefile: Patched to allow cross-compile with mingw32 on Linux.
- It uses macros instead of referencing dlltool, gcc and g++ directly;
- added a call to ranlib. For example the GC static library can be
- built with:
- make CC=i586-mingw32msvc-gcc RC=i586-mingw32msvc-windres \
- RANLIB=i586-mingw32msvc-ranlib clean GC-static
-
-2005-05-13 Ross Johnson <ross at callisto.canberra.edu.au>
-
- * 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
- cancellation and exception exits; thread abnormal exits go via
- 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
- existence check since we now don't care if the Win32 thread HANDLE has
- been closed; reclaim thread resources if the thread has exited already.
- * ptw32_throw.c (ptw32_throw): For Win32 threads that are not implicit,
- only Call thread cleanup if statically linking, otherwise leave it to
- dllMain.
- * sem_post.c (_POSIX_SEM_VALUE_MAX): Change to SEM_VALUE_MAX.
- * sem_post_multiple.c: Likewise.
- * sem_init.c: Likewise.
-
-2005-05-10 Ross Johnson <ross at callisto.canberra.edu.au>
-
- * pthread_join.c (pthread_join): Add missing check for thread ID
- reference count in thread existence test; reduce extent of the
- existence test since we don't care if the Win32 thread HANDLE has
- been closed.
-
-2005-05-09 Ross Johnson <ross at callisto.canberra.edu.au>
-
- * ptw32_callUserDestroyRoutines.c: Run destructor process (i.e.
- loop over all keys calling destructors) up to
- PTHREAD_DESTRUCTOR_ITERATIONS times if TSD value isn't NULL yet;
- modify assoc management.
- * pthread_key_delete.c: Modify assoc management.
- * ptw32_tkAssocDestroy.c: Fix error in assoc removal from chains.
- * pthread.h
- (_POSIX_THREAD_DESTRUCTOR_ITERATIONS): Define to value specified by

- * manual (directory): Added; see ChangeLog inside.
-
-2005-05-02 Ross Johnson <ross at callisto.canberra.edu.au>
-
- * implement.h (struct pthread_key_t_): Change threadsLock to keyLock
- so as not to be confused with the per thread lock 'threadlock';
- 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.
- - thanks to Richard Hughes at Aculab for discovering the problem.
- * pthread_key_create.c: See above.
- * pthread_key_delete.c: See above.

- * sem_timedwait.c: Modify comments.
-
-2005-04-25 Ross Johnson <ross at callisto.canberra.edu.au>
-
- * ptw32_relmillisecs.c: New module; converts future abstime to
- milliseconds relative to 'now'.
- * pthread_mutex_timedlock.c: Use new ptw32_relmillisecs routine in
- place of internal code; remove the NEED_SEM code - this routine is now
- implemented for builds that define NEED_SEM (WinCE etc)
- * sem_timedwait.c: Likewise; after timeout or cancellation,
- re-attempt to acquire the semaphore in case one has been posted since
- the timeout/cancel occurred. Thanks to Stefan Mueller.
- * Makefile: Add ptw32_relmillisecs.c module; remove
- ptw32_{in,de}crease_semaphore.c modules.
- * GNUmakefile: Likewise.
- * Bmakefile: Likewise.
-
- * sem_init.c: Re-write the NEED_SEM code to be consistent with the
- non-NEED_SEM code, but retaining use of an event in place of the w32 sema
- for w32 systems that don't include semaphores (WinCE);
- the NEED_SEM versions of semaphores has been broken for a long time but is
- now fixed and supports all of the same routines as the non-NEED_SEM case.

- * sem_wait.c: Likewise.
- * sem_post.c: Likewise.
- * sem_post_multple.c: Likewise.

-
- * pthread_once.c: Yet more changes, reverting closer to Gottlob Frege's

- preservation of W32 error codes to make pthread_once transparent to
- GetLastError.
-
-2005-04-11 Ross Johnson <ross at callisto.canberra.edu.au>
-
- * pthread_once.c (pthread_once): Added priority boosting to

- * pthread_setcancelstate.c: Don't check for an async cancel event
- if the library is using alertable async cancel..
-
-2005-03-14 Ross Johnson <ross at callisto.canberra.edu.au>
-
- * 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.
-
-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. The woken thread
- was setting itself as the mutex's owner before the re-acquisition.
-
-2004-11-22 Ross Johnson <rpj at callisto.canberra.edu.au>
-
- * pthread_cond_wait.c (ptw32_cond_wait_cleanup): Undo change
- from 2004-11-02.
- * Makefile (DLL_VER): Added for DLL naming suffix - see README.
- * GNUmakefile (DLL_VER): Likewise.

-
-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
- start of cleanup handler rather than at the end.
- * implement.h (PTW32_THREAD_REUSE_EMPTY): Renamed from *_BOTTOM.
- (ptw32_threadReuseBottom): New global variable.
- * global.c (ptw32_threadReuseBottom): Declare new variable.
- * ptw32_reuse.c (ptw32_reuse): Change reuse LIFO stack to LILO queue
- to more evenly distribute use of reusable thread IDs; use renamed
- PTW32_THREAD_REUSE_EMPTY.
- * ptw32_processTerminate.c (ptw2_processTerminate): Use renamed
- PTW32_THREAD_REUSE_EMPTY.
-
-2004-10-31 Ross Johnson <rpj at callisto.canberra.edu.au>
-
- * 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_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. The failing
- test is tests\semaphore4.c.
- * sem_wait.c (sem_wait): Implemented user space check model.
- * sem_post.c (sem_post): Likewise.
- * sem_trywait.c (sem_trywait): Likewise.

- * pthread_mutex_lock.c: Replace the semaphore wait with the event wait.
- * pthread_mutex_trylock.c: Likewise.
- * pthread_mutex_timedlock.c: Likewise.
- * pthread_mutex_unlock.c: Set the event.
-
-2004-10-14 Ross Johnson <rpj at callisto.canberra.edu.au>
-
- * 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).
- * 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_InterlockedExchange.
- * implement.h (PTW32_INTERLOCKED_EXCHANGE): Set default to
- InterlockedExchange().
- * Makefile: Building using /Ob2 so that asm sections within inline
- functions are inlined.

- * 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. Idea suggested by Alexander Terekhov - see:

- inlining.
- * GNUmakefile: Add commandline option to use inlined
- InterlockedCompareExchange().
- * Makefile: Likewise.
-
-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.
-
-2004-09-09 Tristan Savatier <tristan at mpegtv.com>
- * pthread.h (struct pthread_once_t_): Qualify the 'done' element
- as 'volatile'.
- * pthread_once.c: Concerned about possible race condition,
- specifically on MPU systems re concurrent access to multibyte types.
- [Maintainer's note: the race condition is harmless on SPU systems
- and only a problem on MPU systems if concurrent access results in an
- exception (presumably generated by a hardware interrupt). There are
- other instances of similar harmless race conditions that have not
- been identified as issues.]
-

- tests in an attempt to improve efficiency and remove a race
- condition.
-
-2004-08-23 Ross Johnson <rpj at callisto.canberra.edu.au>
-
- * create.c (pthread_create): Don't create a thread if the thread
- id pointer location (first arg) is inaccessible. A memory
- protection fault will result if the thread id arg isn't an accessible
- location. This is consistent with GNU/Linux but different to
- Solaris or MKS (and possibly others), which accept NULL as meaning
- 'don't return the created thread's ID'. Applications that run
- using pthreads-win32 will run on all other POSIX threads
- implementations, at least w.r.t. this feature.
-
- It was decided not to copy the Solaris et al behaviour because,
- although it would have simplified some application porting (but only
- from Solaris to Windows), the feature is not technically necessary,
- and the alternative segfault behaviour helps avoid buggy application
- code.

-
- * 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

-
-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

-
- * 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

-
- * 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

-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>

-
-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.
-
-

- 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.
-

-
-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.
- (ptw32_cond_list_tail): New variable.
- (ptw32_cond_list_cs): New critical section.

- async cancel request.
- * private.c: Likewise.
- * condvar.c: Place pragmas around cleanup_push/pop to turn

-2002-01-27 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * mutex.c (pthread_mutex_timedlock): New function suggested by

- 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.

-
- * 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

- * semaphore.c (sem_init): Fix typo and missing bracket

- * barrier.c: Move _LONG and _LPLONG defines into
- implement.h; rename to PTW32_INTERLOCKED_LONG and
- PTW32_INTERLOCKED_LPLONG respectively.
- * spin.c: Likewise; ptw32_interlocked_compare_exchange used
- in place of InterlockedCompareExchange directly.
- * global.c (ptw32_interlocked_compare_exchange): Add
- prototype for this new routine pointer to be used when
- InterlockedCompareExchange isn't supported by Windows.
- * nonportable.c (pthread_win32_process_attach_np): Check for
- support of InterlockedCompareExchange in kernel32 and assign its
- address to ptw32_interlocked_compare_exchange if it exists, or
- our own ix86 specific implementation ptw32_InterlockedCompareExchange.
- *private.c (ptw32_InterlockedCompareExchange): An
- implementation of InterlockedCompareExchange() which is
- specific to ix86; written directly in assembler for either
- MSVC or GNU C; needed because Windows 95 doesn't support
- InterlockedCompareExchange().
-
- * sched.c (sched_get_priority_min): Extend to return
- THREAD_PRIORITY_IDLE.
- (sched_get_priority_max): Extend to return
- THREAD_PRIORITY_CRITICAL.
-
-2001-10-15 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * spin.c (pthread_spin_lock): PTHREAD_SPINLOCK_INITIALIZER
- was causing a program fault.
- (pthread_spin_init): Could have alloced memory
- without freeing under some error conditions.
-
- * mutex.c (pthread_mutex_init): Move memory
- allocation of mutex struct after checking for
- PROCESS_SHARED.
-
-2001-10-12 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * spin.c (pthread_spin_unlock): Was not returning
- EPERM if the spinlock was not locked, for multi CPU
- machines.
-
-2001-10-08 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * spin.c (pthread_spin_trylock): Was not returning
- EBUSY for multi CPU machines.
-
-2001-08-24 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * condvar.c (pthread_cond_destroy): Remove cv element
- that is no longer used.
- * implement.h: Likewise.
-
-2001-08-23 Alexander Terekhov <TEREKHOV at de.ibm.com>
-
- * condvar.c (pthread_cond_destroy): fix bug with
- respect to deadlock in the case of concurrent
- _destroy/_unblock; a condition variable can be destroyed
- immediately after all the threads that are blocked on
- it are awakened.
-
-2001-08-23 Phil Frisbie, Jr. <phil at hawksoft.com>
-
- * tsd.c (pthread_getspecific): Preserve the last
- winsock error [from WSAGetLastError()].
-
-2001-07-18 Scott McCaskill <scott at magruder.org>
-
- * mutex.c (pthread_mutexattr_init): Return ENOMEM
- immediately and don't dereference the NULL pointer
- if calloc fails.
- (pthread_mutexattr_getpshared): Don't dereference
- a pointer that is possibly NULL.
- * barrier.c (pthread_barrierattr_init): Likewise
- (pthread_barrierattr_getpshared): Don't dereference
- a pointer that is possibly NULL.
- * condvar.c (pthread_condattr_getpshared): Don't dereference
- a pointer that is possibly NULL.
-
-2001-07-15 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * rwlock.c (pthread_rwlock_wrlock): Is allowed to be
- a cancelation point; re-enable deferred cancelability
- 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
- elements.
- * private.c (ptw32_threadStart): Removed some comments.
-
-2001-07-10 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * barrier.c: Revamped to fix the race condition. Two alternating
- semaphores are used instead of the PulseEvent. Also improved
- overall throughput by returning PTHREAD_BARRIER_SERIAL_THREAD
- to the first waking thread.
- * 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>
-
- * spin.c: Revamped and working; included static initialiser.

- * rwlock.c: Likewise.
- * private.c: Add support for spinlock initialiser.
- * global.c: Likewise.
- * implement.h: Likewise.
- * pthread.h (PTHREAD_SPINLOCK_INITIALIZER): Fix typo.
-
-2001-07-05 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * barrier.c: Remove static initialisation - irrelevent
- for this object.
- * pthread.h (PTHREAD_BARRIER_INITIALIZER): Removed.
- * rwlock.c (pthread_rwlock_wrlock): This routine is
- not a cancelation point - disable deferred
- cancelation around call to pthread_cond_wait().
-
-2001-07-05 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * spin.c: New module implementing spin locks.
- * barrier.c: New module implementing barriers.
- * pthread.h (_POSIX_SPIN_LOCKS): defined.
- (_POSIX_BARRIERS): Defined.
- (pthread_spin_*): Defined.
- (pthread_barrier*): Defined.
- (PTHREAD_BARRIER_SERIAL_THREAD): Defined.
- * implement.h (pthread_spinlock_t_): Defined.
- (pthread_barrier_t_): Defined.
- (pthread_barrierattr_t_): Defined.
-
- * mutex.c (pthread_mutex_lock): Return with the error
- if an auto-initialiser initialisation fails.
-
- * nonportable.c (pthread_getprocessors_np): New; gets the
- number of available processors for the current process.
-
-2001-07-03 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * pthread.h (_POSIX_READER_WRITER_LOCKS): Define it
- if not already defined.
-
-2001-07-01 Alexander Terekhov <TEREKHOV at de.ibm.com>
-
- * 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
- POSIX standard.
- * sched.h (SCHED_*): Moved from pthread.h.
- (pid_t): Defined if necessary.
- (sched_setscheduler): Defined.
- (sched_getscheduler): Defined.
- * pthread.def (sched_setscheduler): Exported.
- (sched_getscheduler): Likewise.
-
-2001-06-23 Ralf Brese <Ralf.Brese at pdb4.siemens.de>
-
- * create.c (pthread_create): Set thread priority from
- thread attributes.
-
-2001-06-18 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * Made organisational-only changes to UWIN additions.
- * dll.c (dllMain): Moved UWIN process attach code
- to pthread_win32_process_attach_np(); moved
- instance of pthread_count to global.c.
- * global.c (pthread_count): Moved from dll.c.
- * nonportable.c (pthread_win32_process_attach_np):
- Moved _UWIN code to here from dll.c.
- * implement.h (pthread_count): Define extern int.
- * create.c (pthread_count): Remove extern int.
- * private.c (pthread_count): Likewise.
- * exit.c (pthread_count): Likewise.
-
-2001-06-18 David Korn <dgk at research.att.com>
-
- * dll.c: Added changes necessary to work with UWIN.
- * create.c: Likewise.
- * pthread.h: Likewise.
- * misc.c: Likewise.
- * exit.c: Likewise.
- * private.c: Likewise.
- * implement.h: Likewise.
- There is some room at the start of struct pthread_t_
- to implement the signal semantics in UWIN's posix.dll
- although this is not yet complete.
- * Nmakefile: Compatible with UWIN's Nmake utility.
- * Nmakefile.tests: Likewise - for running the tests.
-
-2001-06-08 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * semaphore.h (sem_t): Fixed for compile and test.
- * implement.h (sem_t_): Likewise.
- * semaphore.c: Likewise.
- * private.c (ptw32_sem_timedwait): Updated to use new
- opaque sem_t.
-
-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>
-
- * mutex.c (pthread_mutexattr_init): Remove
- ptw32_mutex_default_kind.
-
-2001-06-05 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * nonportable.c (pthread_mutex_setdefaultkind_np):
- Remove - should not have been included in the first place.
- (pthread_mutex_getdefaultkind_np): Likewise.
- * global.c (ptw32_mutex_default_kind): Likewise.
- * mutex.c (pthread_mutex_init): Remove use of
- ptw32_mutex_default_kind.
- * 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.

- * 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.
-

-
- * 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

-
- * GNUmakefile(_WIN32_WINNT=0x400): Define in CFLAGS;
- doesn't seem to be needed though.
-
- * cancel.c (pthread_cancel): Must get "self" through

- struct is built for non-POSIX threads; return an error
- if this fails

-
-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>

- 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

-
- * 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.

-
- * All applicable: Change _pthread_ prefix to

-
- * 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

- "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.

-
- * ANNOUNCE: Update information.
-
-2000-08-12 Ross Johnson <rpj at special.ise.canberra.edu.au>

- 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.

- 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>

-
-2000-08-05 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * pthread.h (PtW32CatchAll): Add macro. When compiling

-
-2000-08-03 Ross Johnson <rpj at special.ise.canberra.edu.au>

- 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

- 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>
-
- * dll.c: Include resource leakage work-around. This is a

-
- * create.c (pthread_create): Set threadH to 0 (zero)

- ptw32_exception_services which is no longer needed.
-
- * pthread.h (ptw32_exception_services): Remove extern.
- (ptw32_get_exception_services_code): Add function prototype;
- use this to return EXCEPTION_PTW32_SERVICES value instead of
- using the ptw32_exception_services variable which I had
- trouble exporting through pthread.def.
-
- * global.c (ptw32_exception_services): Remove declaration.
-
-1999-11-22 Ross Johnson <rpj at special.ise.canberra.edu.au>

-
- * dll.c (dllMain): Free kernel32 ASAP.
- If TryEnterCriticalSection is not being used, then free
- the kernel32.dll handle now, rather than leaving it until
- DLL_PROCESS_DETACH.
-
- Note: this is not a pedantic exercise in freeing unused
- resources! It is a work-around for a bug in Windows 95
- (see microsoft knowledge base article, Q187684) which
- does Bad Things when FreeLibrary is called within
- the DLL_PROCESS_DETACH code, in certain situations.
- Since w95 just happens to be a platform which does not
- provide TryEnterCriticalSection, the bug will be
- effortlessly avoided.

- making pthread_cond_t (and other objects like it) opaque again, if
- possible, later.

-
-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

-
-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

- 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.

+2005-05-30 Vladimir Kliatchko <vladimir at kliatchko.com>
+
+ * 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.

+2005-05-25 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
+ init_routine thread is cancelled yet still release all waiters when
+ done. Simplify once_control state checks to improve efficiency
+ further.

+
+ * GNUmakefile: Patched to allow cross-compile with mingw32 on Linux.
+ It uses macros instead of referencing dlltool, gcc and g++ directly;
+ added a call to ranlib. For example the GC static library can be

+ * 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
+ cancellation and exception exits; thread abnormal exits go via
+ 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
+ existence check since we now don't care if the Win32 thread HANDLE has
+ been closed; reclaim thread resources if the thread has exited already.
+ * ptw32_throw.c (ptw32_throw): For Win32 threads that are not implicit,

+
+ * implement.h (struct pthread_key_t_): Change threadsLock to keyLock
+ so as not to be confused with the per thread lock 'threadlock';
+ 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.
+ - thanks to Richard Hughes at Aculab for discovering the problem.

+ for w32 systems that don't include semaphores (WinCE);
+ the NEED_SEM versions of semaphores has been broken for a long time but is

+
+ * 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
+ FIFO waiting threads. The next waiting FIFO thread gets a spurious

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

+
+ * 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_reuse.c (ptw32_reuse): Change reuse LIFO stack to LILO queue
+ to more evenly distribute use of reusable thread IDs; use renamed

+
+ * 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.

+
+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.

+
+2004-10-14 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * 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).
+ * 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

+ (PTW32_INTERLOCKED_EXCHANGE): Sets up macro to use inlined
+ ptw32_InterlockedExchange.
+ * implement.h (PTW32_INTERLOCKED_EXCHANGE): Set default to

+ 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. Idea suggested by Alexander Terekhov - see:
+ http://sources.redhat.com/ml/pthreads-win32/2003/msg00108.html

+ * Makefile: Likewise.
+
+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.
+
+2004-09-09 Tristan Savatier <tristan at mpegtv.com>
+ * pthread.h (struct pthread_once_t_): Qualify the 'done' element
+ as 'volatile'.
+ * pthread_once.c: Concerned about possible race condition,
+ specifically on MPU systems re concurrent access to multibyte types.
+ [Maintainer's note: the race condition is harmless on SPU systems
+ and only a problem on MPU systems if concurrent access results in an
+ exception (presumably generated by a hardware interrupt). There are
+ other instances of similar harmless race conditions that have not
+ been identified as issues.]
+
+2004-09-09 Ross Johnson <rpj at callisto.canberra.edu.au>

+ tests in an attempt to improve efficiency and remove a race
+ condition.
+
+2004-08-23 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * create.c (pthread_create): Don't create a thread if the thread
+ id pointer location (first arg) is inaccessible. A memory
+ protection fault will result if the thread id arg isn't an accessible
+ location. This is consistent with GNU/Linux but different to
+ Solaris or MKS (and possibly others), which accept NULL as meaning
+ 'don't return the created thread's ID'. Applications that run
+ using pthreads-win32 will run on all other POSIX threads
+ implementations, at least w.r.t. this feature.
+
+ It was decided not to copy the Solaris et al behaviour because,
+ although it would have simplified some application porting (but only
+ from Solaris to Windows), the feature is not technically necessary,
+ and the alternative segfault behaviour helps avoid buggy application
+ code.

+
+2003-10-15 Alex Blanco <Alex.Blanco at motorola.com>
+
+ * sem_init.c (sem_init): Would call CreateSemaphore even if the sema

+ 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

+
+ * 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

+2003-08-13 Ross Johnson <rpj at ise.canberra.edu.au>
+
+ * pthread_getschedparam.c (pthread_getschedparam): An invalid thread ID

+ * ptw32_threadDestroy.c (ptw32_threadDestroy): pthread_t structs are

+
+ * 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.

+ (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

+
+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

+ 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

+ 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

+ breaking the avoidance logic.
+
+2002-07-30 Ross Johnson <rpj at ise.canberra.edu.au>
+

+
+
+2002-06-08 Ross Johnson <rpj at special.ise.canberra.edu.au>

+
+
+2002-06-04 Rob Fanner <rfanner at stonethree.com>
+
+ * sem_getvalue.c (sem_getvalue): The Johnson M. Hart

+ 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

+ * condvar.c (ptw32_cond_timedwait): Use the new sem_timedwait()

+
+2001-07-10 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+

+ the last (signalling) thread to hit the barrier yields

+ to complete.
+
+2001-07-07 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * barrier.c: Changed synchronisation mechanism to a

+2001-07-03 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * pthread.h (_POSIX_READER_WRITER_LOCKS): Define it
+ if not already defined.
+
+2001-07-01 Alexander Terekhov <TEREKHOV at de.ibm.com>
+
+ * 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
+ POSIX standard.
+ * sched.h (SCHED_*): Moved from pthread.h.
+ (pid_t): Defined if necessary.
+ (sched_setscheduler): Defined.
+ (sched_getscheduler): Defined.
+ * pthread.def (sched_setscheduler): Exported.
+ (sched_getscheduler): Likewise.
+
+2001-06-23 Ralf Brese <Ralf.Brese at pdb4.siemens.de>
+
+ * create.c (pthread_create): Set thread priority from

+
+2001-06-18 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * Made organisational-only changes to UWIN additions.
+ * dll.c (dllMain): Moved UWIN process attach code
+ to pthread_win32_process_attach_np(); moved
+ instance of pthread_count to global.c.
+ * global.c (pthread_count): Moved from dll.c.
+ * nonportable.c (pthread_win32_process_attach_np):
+ Moved _UWIN code to here from dll.c.

+ * exit.c (pthread_count): Likewise.
+
+2001-06-18 David Korn <dgk at research.att.com>
+
+ * dll.c: Added changes necessary to work with UWIN.
+ * create.c: Likewise.
+ * pthread.h: Likewise.
+ * misc.c: Likewise.
+ * exit.c: Likewise.
+ * private.c: Likewise.
+ * implement.h: Likewise.
+ There is some room at the start of struct pthread_t_
+ to implement the signal semantics in UWIN's posix.dll
+ although this is not yet complete.
+ * Nmakefile: Compatible with UWIN's Nmake utility.
+ * Nmakefile.tests: Likewise - for running the tests.
+
+2001-06-08 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * semaphore.h (sem_t): Fixed for compile and test.
+ * implement.h (sem_t_): Likewise.
+ * semaphore.c: Likewise.
+ * private.c (ptw32_sem_timedwait): Updated to use new
+ opaque sem_t.
+
+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>
+
+ * mutex.c (pthread_mutexattr_init): Remove
+ ptw32_mutex_default_kind.
+
+2001-06-05 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * nonportable.c (pthread_mutex_setdefaultkind_np):
+ Remove - should not have been included in the first place.
+ (pthread_mutex_getdefaultkind_np): Likewise.

+ * mutex.c (pthread_mutex_init): Remove use of

+ * 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>

+
+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.

+ 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

+
+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

+
+ * 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

+
+ * private.c (ptw32_throw): New function to provide

+ (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>

+
+2000-08-05 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h (PtW32CatchAll): Add macro. When compiling

+ 'PtW32CatchAll' must be used in place of any 'catch( ... )'
+ if the application wants pthread cancelation or

+2000-07-25 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * create.c (pthread_create): Force new threads to wait until

+ 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

+
+ * tsd.c (pthread_key_create): If a destructor was given
+ and the pthread_mutex_init failed, then would try to

+ (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

+ * dll.c (dllMain): Free kernel32 ASAP.
+ If TryEnterCriticalSection is not being used, then free

+
+ Note: this is not a pedantic exercise in freeing unused

+ (see microsoft knowledge base article, Q187684) which
+ does Bad Things when FreeLibrary is called within

+ Since w95 just happens to be a platform which does not

+ possible, later.

+
+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

+ 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>
+

+ * mutex.c (pthread_mutexattr_setpshared): This optional function

-# The library can be built with some alternative behaviour to
-# 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).

+# The library can be built with some alternative behaviour to
+# 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).

-CURRENT CVS HEAD Version
-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.
-

-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.
-

--------------------
-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.
-

-- 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
---------------

-
-
-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. 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.
-- Michael Johnson <michaelj@maine.rr.com>
-
-
-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.

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

+-------------------
+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.

+
+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.

+
+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

+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.

+-------------------
+
+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.

+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.

+scalar, or members, if it is an aggregate, to store information that may be
+extra to the unique identifying value of the ID. As a result, pthread_t values
+may not be directly comparable.
+
+If you want your code to be portable you must adhere to the following contraints:
+
+1) Don't assume it is a scalar data type, e.g. an integer or pointer value. There
+are several other implementations where pthread_t is also a struct. See our FAQ
+Question 11 for our reasons for defining pthread_t as a struct.
+
+2) You must not compare them using relational or equality operators. You must use
+the API function pthread_equal() to test for equality.
+
+3) Never attempt to reference individual members.
+
+
+The problem
+
+Certain applications would like to be able to access only the 'pure' pthread_t
+id values, primarily to use as keys into data structures to manage threads or
+thread-related data, but this is not possible in a maximally portable and
+standards compliant way for current POSIX threads implementations.
+
+For implementations that define pthread_t as a scalar, programmers often employ
+direct relational and equality operators on pthread_t. This code will break when
+ported to an implementation that defines pthread_t as an aggregate type.
+
+For implementations that define pthread_t as an aggregate, e.g. a struct,
+programmers can use memcmp etc., but then face the prospect that the struct may
+include alignment padding bytes or bits as well as extra implementation-specific
+members that are not part of the unique identifying value.
+
+[While this is not currently the case for pthreads-win32, opacity also
+means that an implementation is free to change the definition, which should
+generally only require that applications be recompiled and relinked, not
+rewritten.]
+
+
+Doesn't the compiler take care of padding?
+
+The C89 and later standards only effectively guarrantee element-by-element
+equivalence following an assignment or pass by value of a struct or union,
+therefore undefined areas of any two otherwise equivalent pthread_t instances
+can still compare differently, e.g. attempting to compare two such pthread_t
+variables byte-by-byte, e.g. memcmp(&t1, &t2, sizeof(pthread_t) may give an
+incorrect result. In practice I'm reasonably confident that compilers routinely
+also copy the padding bytes, mainly because assignment of unions would be far
+too complicated otherwise. But it just isn't guarranteed by the standard.
+
+Illustration:
+
+We have two thread IDs t1 and t2
+
+pthread_t t1, t2;
+
+In an application we create the threads and intend to store the thread IDs in an
+ordered data structure (linked list, tree, etc) so we need to be able to compare
+them in order to insert them initially and also to traverse.
+
+Suppose pthread_t contains undefined padding bits and our compiler copies our
+pthread_t [struct] element-by-element, then for the assignment:
+
+pthread_t temp = t1;
+
+temp and t1 will be equivalent and correct but a byte-for-byte comparison such as
+memcmp(&temp, &t1, sizeof(pthread_t)) == 0 may not return true as we expect because
+the undefined bits may not have the same values in the two variable instances.
+
+Similarly if passing by value under the same conditions.
+
+If, on the other hand, the undefined bits are at least constant through every
+assignment and pass-by-value then the byte-for-byte comparison
+memcmp(&temp, &t1, sizeof(pthread_t)) == 0 will always return the expected result.
+How can we force the behaviour we need?
+
+
+Solutions
+
+Adding new functions to the standard API or as non-portable extentions is
+the only reliable and portable way to provide the necessary operations.
+Remember also that POSIX is not tied to the C language. The most common
+functions that have been suggested are:
+
+pthread_null()
+pthread_compare()
+pthread_hash()
+
+A single more general purpose function could also be defined as a
+basis for at least the last two of the above functions.
+
+First we need to list the freedoms and constraints with restpect
+to pthread_t so that we can be sure our solution is compatible with the
+standard.
+
+What is known or may be deduced from the standard:
+1) pthread_t must be able to be passed by value, so it must be a single object.
+2) from (1) it must be copyable so cannot embed thread-state information, locks
+or other volatile objects required to manage the thread it associates with.
+3) pthread_t may carry additional information, e.g. for debugging or to manage
+itself.
+4) there is an implicit requirement that the size of pthread_t is determinable
+at compile-time and size-invariant, because it must be able to copy the object
+(i.e. through assignment and pass-by-value). Such copies must be genuine
+duplicates, not merely a copy of a pointer to a common instance such as
+would be the case if pthread_t were defined as an array.
+
+
+Suppose we define the following function:
+
+/* This function shall return it's argument */
+pthread_t* pthread_normalize(pthread_t* thread);
+
+For scalar or aggregate pthread_t types this function would simply zero any bits
+within the pthread_t that don't uniquely identify the thread, including padding,
+such that client code can return consistent results from operations done on the
+result. If the additional bits are a pointer to an associate structure then
+this function would ensure that the memory used to store that associate
+structure does not leak. After normalization the following compare would be
+valid and repeatable:
+
+memcmp(pthread_normalize(&t1),pthread_normalize(&t2),sizeof(pthread_t))
+
+Note 1: such comparisons are intended merely to order and sort pthread_t values
+and allow them to index various data structures. They are not intended to reveal
+anything about the relationships between threads, like startup order.
+
+Note 2: the normalized pthread_t is also a valid pthread_t that uniquely
+identifies the same thread.
+
+Advantages:
+1) In most existing implementations this function would reduce to a no-op that
+emits no additional instructions, i.e after in-lining or optimisation, or if
+defined as a macro:
+#define pthread_normalise(tptr) (tptr)
+
+2) This single function allows an application to portably derive
+application-level versions of any of the other required functions.
+
+3) It is a generic function that could enable unanticipated uses.
+
+Disadvantages:
+1) Less efficient than dedicated compare or hash functions for implementations
+that include significant extra non-id elements in pthread_t.
+
+2) Still need to be concerned about padding if copying normalized pthread_t.
+See the later section on defining pthread_t to neutralise padding issues.
+
+Generally a pthread_t may need to be normalized every time it is used,
+which could have a significant impact. However, this is a design decision
+for the implementor in a competitive environment. An implementation is free
+to define a pthread_t in a way that minimises or eliminates padding or
+renders this function a no-op.
+
+Hazards:
+1) Pass-by-reference directly modifies 'thread' so the application must
+synchronise access or ensure that the pointer refers to a copy. The alternative
+of pass-by-value/return-by-value was considered but then this requires two copy
+operations, disadvantaging implementations where this function is not a no-op
+in terms of speed of execution. This function is intended to be used in high
+frequency situations and needs to be efficient, or at least not unnecessarily
+inefficient. The alternative also sits awkwardly with functions like memcmp.
+
+2) [Non-compliant] code that uses relational and equality operators on
+arithmetic or pointer style pthread_t types would need to be rewritten, but it
+should be rewritten anyway.

+pthread_t id = thread, non-id = thread;
+bitclear((void*) &non-id, (void*) pthread_normalize(&id), sizeof(pthread_t));
+
+
+A pthread_t type change proposal to neutralise the effects of padding
+
+Even if pthread_nornalize() is available, padding is still a problem because
+the standard only garrantees element-by-element equivalence through
+copy operations (assignment and pass-by-value). So padding bit values can
+still change randomly after calls to pthread_normalize().
+
+[I suspect that most compilers take the easy path and always byte-copy anyway,
+partly because it becomes too complex to do (e.g. unions that contain sub-aggregates)
+but also because programmers can easily design their aggregates to minimise and
+often eliminate padding].
+
+How can we eliminate the problem of padding bytes in structs? Could
+defining pthread_t as a union rather than a struct provide a solution?
+
+In fact, the Linux pthread.h defines most of it's pthread_*_t objects (but not
+pthread_t itself) as unions, possibly for this and/or other reasons. We'll
+borrow some element naming from there but the ideas themselves are well known
+- the __align element used to force alignment of the union comes from K&R's
+storage allocator example.
+
+/* Essentially our current pthread_t renamed */
+typedef struct {
+ struct thread_state_t * __p;
+ long __x; /* sequence counter */
+} thread_id_t;
+
+Ensuring that the last element in the above struct is a long ensures that the
+overall struct size is a multiple of sizeof(long), so there should be no trailing
+padding in this struct or the union we define below.
+(Later we'll see that we can handle internal but not trailing padding.)
+
+/* New pthread_t */
+typedef union {
+ char __size[sizeof(thread_id_t)]; /* array as the first element */
+ thread_id_t __tid;
+ long __align; /* Ensure that the union starts on long boundary */
+} pthread_t;
+
+This guarrantees that, during an assignment or pass-by-value, the compiler copies
+every byte in our thread_id_t because the compiler guarrantees that the __size
+array, which we have ensured is the equal-largest element in the union, retains
+equivalence.
+
+This means that pthread_t values stored, assigned and passed by value will at least
+carry the value of any undefined padding bytes along and therefore ensure that
+those values remain consistent. Our comparisons will return consistent results and
+our hashes of [zero initialised] pthread_t values will also return consistent
+results.
+
+We have also removed the need for a pthread_null() function; we can initialise
+at declaration time or easily create our own const pthread_t to use in assignments
+later:
+
+const pthread_t null_tid = {0}; /* braces are required */
+
+pthread_t t;
+...
+t = null_tid;
+
+
+Note that we don't have to explicitly make use of the __size array at all. It's
+there just to force the compiler behaviour we want.
+
+
+Partial solutions without a pthread_normalize function
+
+
+An application-level pthread_null and pthread_compare proposal
+(and pthread_hash proposal by extention)
+
+In order to deal with the problem of scalar/aggregate pthread_t type disparity in
+portable code I suggest using an old-fashioned union, e.g.:
+
+Contraints:
+- there is no padding, or padding values are preserved through assignment and
+ pass-by-value (see above);
+- there are no extra non-id values in the pthread_t.
+
+
+Example 1: A null initialiser for pthread_t variables...
+
+typedef union {
+ unsigned char b[sizeof(pthread_t)];
+ pthread_t t;
+} init_t;
+
+const init_t initial = {0};
+
+pthread_t tid = initial.t; /* init tid to all zeroes */
+
+
+Example 2: A comparison function for pthread_t values
+
+typedef union {
+ unsigned char b[sizeof(pthread_t)];
+ pthread_t t;
+} pthcmp_t;
+
+int pthcmp(pthread_t left, pthread_t right)
+{
+ /*
+ * Compare two pthread handles in a way that imposes a repeatable but arbitrary
+ * ordering on them.
+ * I.e. given the same set of pthread_t handles the ordering should be the same
+ * each time but the order has no particular meaning other than that. E.g.
+ * the ordering does not imply the thread start sequence, or any other
+ * relationship between threads.
+ *
+ * Return values are:
+ * 1 : left is greater than right
+ * 0 : left is equal to right
+ * -1 : left is less than right
+ */
+ int i;
+ pthcmp_t L, R;
+ L.t = left;
+ R.t = right;
+ for (i = 0; i < sizeof(pthread_t); i++)
+ {
+ if (L.b[i] > R.b[i])
+ return 1;
+ else if (L.b[i] < R.b[i])
+ return -1;
+ }
+ return 0;
+}
+
+It has been pointed out that the C99 standard allows for the possibility that
+integer types also may include padding bits, which could invalidate the above
+method. This addition to C99 was specifically included after it was pointed
+out that there was one, presumably not particularly well known, architecture
+that included a padding bit in it's 32 bit integer type. See section 6.2.6.2
+of both the standard and the rationale, specifically the paragraph starting at
+line 16 on page 43 of the rationale.
+
+
+An aside
+
+Certain compilers, e.g. gcc and one of the IBM compilers, include a feature
+extention: provided the union contains a member of the same type as the
+object then the object may be cast to the union itself.
+
+We could use this feature to speed up the pthrcmp() function from example 2
+above by casting rather than assigning the pthread_t arguments to the union, e.g.:
+
+int pthcmp(pthread_t left, pthread_t right)
+{
+ /*
+ * Compare two pthread handles in a way that imposes a repeatable but arbitrary
+ * ordering on them.
+ * I.e. given the same set of pthread_t handles the ordering should be the same
+ * each time but the order has no particular meaning other than that. E.g.
+ * the ordering does not imply the thread start sequence, or any other
+ * relationship between threads.
+ *
+ * Return values are:
+ * 1 : left is greater than right
+ * 0 : left is equal to right
+ * -1 : left is less than right
+ */
+ int i;
+ for (i = 0; i < sizeof(pthread_t); i++)
+ {
+ if (((pthcmp_t)left).b[i] > ((pthcmp_t)right).b[i])
+ return 1;
+ else if (((pthcmp_t)left).b[i] < ((pthcmp_t)right).b[i])
+ return -1;
+ }
+ return 0;
+}
+
+
+Result thus far
+
+We can't remove undefined bits if they are there in pthread_t already, but we have
+attempted to render them inert for comparison and hashing functions by making them
+consistent through assignment, copy and pass-by-value.
+
+Note: Hashing pthread_t values requires that all pthread_t variables be initialised
+to the same value (usually all zeros) before being assigned a proper thread ID, i.e.
+to ensure that any padding bits are zero, or at least the same value for all
+pthread_t. Since all pthread_t values are generated by the library in the first
+instance this need not be an application-level operation.
+
+
+Conclusion
+
+I've attempted to resolve the multiple issues of type opacity and the possible
+presence of undefined bits and bytes in pthread_t values, which prevent
+applications from comparing or hashing pthread handles.
+
+Two complimentary partial solutions have been proposed, one an application-level
+scheme to handle both scalar and aggregate pthread_t types equally, plus a
+definition of pthread_t itself that neutralises padding bits and bytes by
+coercing semantics out of the compiler to eliminate variations in the values of
+padding bits.
+
+I have not provided any solution to the problem of handling extra values embedded
+in pthread_t, e.g. debugging or trap information that an implementation is entitled
+to include. Therefore none of this replaces the portability and flexibility of API
+functions but what functions are needed? The threads standard is unlikely to
+include that can be implemented by a combination of existing features and more
+generic functions (several references in the threads rationale suggest this.
+Therefore I propose that the following function could replace the several functions
+that have been suggested in conversations:
+
+pthread_t * pthread_normalize(pthread_t * handle);
+
+For most existing pthreads implementations this function, or macro, would reduce to
+a no-op with zero call overhead.

- * 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.

+ * 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.

- * -------------------------------------------------------------
- *
- *
- * 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.

+/*
+ * -------------------------------------------------------------
+ *
+ *
+ * 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/

- * 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.

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

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

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

-
- * detach1.c: New test.
- * join1.c: Reduce sleep times.
- * join0.c: Remove MSVCRT conditional compile - join should always

-
-2005-04-18 Ross Johnson <rpj@callisto.canberra.edu.au>
-

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

-2004-05-16 Ross Johnson <rpj@callisto.canberra.edu.au>
-
- * cancel9.c: New test.
- * cancel3.c: Remove inappropriate conditional compilation;

- * cancel5.c: Likewise.
- * GNUmakefile: Can now build individual test app using default
- C version of library using 'make clean testname.c'.

-2003-09-18 Ross Johnson <rpj@callisto.canberra.edu.au>
-
- * benchtest.h: Move old mutex code into benchlib.c.
- * benchlib.c: New statically linked module to ensure that
- bench apps don't inline the code and therefore have an unfair
- advantage over the pthreads lib routines. Made little or no
- difference.

- * benchtest5.c: Likewise.
- * benchtest2.c: Fix misinformation in output report.

- * valid1.c: New test.
- * valid2.c: New test.
- * kill1.c: New test.

-2003-07-19 Ross Johnson <rpj@ise.canberra.edu.au>
-
- * eyal1.c (waste_time): Make threads do more work to ensure that
- all threads get to do some work.
- * semaphore1.c: Make it clear that certain errors are expected.
- * exception2.c (non_MSVC code sections): Change to include

- * exception3.c (non_MSVC code sections): Likewise; qualify std::
- namespace entities where necessary.
- * GNUmakefile: modified to work in the MsysDTK (newer MinGW)
- environment; define CC as gcc or g++ as appropriate because
- using gcc -x c++ doesn't link with required c++ libs by default,
- but g++ does.
-
-2002-12-11 Ross Johnson <ross@special.ise.canberra.edu.au>
-

-
-2002-03-02 Ross Johnson <rpj@special.ise.canberra.edu.au>

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

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

+ * Makefile: Some refinement.
+
+ * *.c: More exhaustive checking through assertions; clean up;
+ add some more tests.
+
+ * Makefile: Now actually runs the tests.
+
+ * tests.h: Define our own assert macro. The Mingw32
+ version pops up a dialog but we want to run non-interactively.
+
+ * equal1.c: use assert a little more directly so that it
+ prints the actual call statement.
+
+ * exit1.c: Modify to return 0 on success, 1 on failure.
+
+1999-02-22 Ross Johnson <rpj@ise.canberra.edu.au>
+
+ * self2.c: Bring up to date.
+
+ * self3.c: Ditto.
+
+1999-02-21 Ben Elliston <bje@cygnus.com>
+
+ * README: Update.
+
+ * Makefile: New file. Run all tests automatically. Primitive tests
+ are run first; more complex tests are run last.
+
+ * count1.c: New test. Validate the thread count.
+
+ * exit2.c: Perform a simpler test.
+
+ * exit3.c: New test. Replaces exit2.c, since exit2.c needs to
+ perform simpler checking first.
+
+ * create1.c: Update to use the new testsuite exiting convention.
+
+ * equal1.c: Likewise.
+
+ * mutex1.c: Likewise.
+
+ * mutex2.c: Likewise.
+
+ * once1.c: Likewise.
+
+ * self2.c: Likewise.
+
+ * self3.c: Likewise.
+
+ * tsd1.c: Likewise.
+
+1999-02-20 Ross Johnson <rpj@ise.canberra.edu.au>
+
+ * mutex2.c: Test static mutex initialisation.
+
+ * test.h: New. Declares a table mapping error numbers to
+ error names.
+
+1999-01-17 Ross Johnson <rpj@ise.canberra.edu.au>
+
+ * runtest: New script to build and run a test in the tests directory.
+
+Wed Dec 30 11:22:44 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
+
+ * tsd1.c: Re-written. See comments at start of file.
+ * Template.c: New. Contains skeleton code and comment template
+ intended to fully document the test.
+
+Fri Oct 16 17:59:49 1998 Ross Johnson <rpj@swan.canberra.edu.au>
+
+ * tsd1.c (destroy_key): Add function. Change diagnostics.
+
+Thu Oct 15 17:42:37 1998 Ross Johnson <rpj@swan.canberra.edu.au>
+
+ * tsd1.c (mythread): Fix some casts and add some message
+ output. Fix inverted conditional.
+
+Mon Oct 12 02:12:29 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
+
+ * tsd1.c: New. Test TSD using 1 key and 2 threads.
+
+1998-09-13 Ben Elliston <bje@cygnus.com>
+
+ * eyal1.c: New file; contributed by Eyal Lebedinsky
+ <eyal@eyal.emu.id.au>.
+
+1998-09-12 Ben Elliston <bje@cygnus.com>
+
+ * exit2.c (func): Return a value.
+ (main): Call the right thread entry function.
+
+1998-07-22 Ben Elliston <bje@cygnus.com>
+
+ * exit2.c (main): Fix size of pthread_t array.
+
+1998-07-10 Ben Elliston <bje@cygnus.com>
+
+ * exit2.c: New file; test pthread_exit() harder.
+
+ * exit1.c: New file; test pthread_exit().
