-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.
-
-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.

-Application Development Environments
-------------------------------------
-
-See the README file for more information.
-
-MSVC:
-MSVC using SEH works. Distribute pthreadVSE.dll with your application.
-MSVC using C++ EH works. Distribute pthreadVCE.dll with your application.
-MSVC using C setjmp/longjmp works. Distribute pthreadVC.dll with your application.
-
-
-Mingw32:
-See the FAQ, Questions 6 and 10.
-
-Mingw using C++ EH works. Distribute pthreadGCE.dll with your application.
-Mingw using C setjmp/longjmp works. Distribute pthreadGC.dll with your application.
-
-
-Cygwin: (http://sourceware.cygnus.com/cygwin/)
-Developers using Cygwin will not need pthreads-win32 since it has POSIX threads
-support. Refer to its documentation for details and extent.
-
-
-UWIN:
-UWIN is a complete Unix-like environment for Windows from AT&T. Pthreads-win32
-doesn't currently support UWIN (and vice versa), but that may change in the
-future.
-
-Generally:
-For convenience, the following pre-built files are available on the FTP site
-(see Availability above):
-
- pthread.h - for POSIX 1c threads
- semaphore.h - for POSIX 1b semaphores
- sched.h - for POSIX 1b scheduling
- pthreadVCE.dll - built with MSVC++ compiler using C++ EH
- pthreadVCE.lib
- pthreadVC.dll - built with MSVC compiler using C setjmp/longjmp
- pthreadVC.lib
- pthreadVSE.dll - built with MSVC compiler using SEH
- pthreadVSE.lib
- pthreadGCE.dll - built with Mingw32 G++ 2.95.2-1
- pthreadGC.dll - built with Mingw32 GCC 2.95.2-1 using setjmp/longjmp
- libpthreadGCE.a - derived from pthreadGCE.dll
- libpthreadGC.a - derived from pthreadGC.dll
- gcc.dll - needed if distributing applications that use
- pthreadGCE.dll (but see the FAQ Q 10 for the latest
- related information)
-
-These are the only files you need in order to build POSIX threads
-applications for Win32 using either MSVC or Mingw32.
-
-See the FAQ file in the source tree for additional information.
-
-
-Documentation
--------------
-
-For the authoritative reference, see the online POSIX
-standard reference at:
-
- http://www.OpenGroup.org
-
-For POSIX Thread API programming, several reference books are
-available:
-
- Programming with POSIX Threads
- David R. Butenhof
- Addison-Wesley (pub)
-
- Pthreads Programming
- By Bradford Nichols, Dick Buttlar & Jacqueline Proulx Farrell
- O'Reilly (pub)
-
-On the web: see the links at the bottom of the pthreads-win32 site:
-
- http://sources.redhat.com/pthreads-win32/
-
- Currently, there is no documentation included in the package apart
- from the copious comments in the source code.
-
-
-
-Enjoy!

-1. Not strictly a bug, more of a gotcha.
-
- Under MS VC++ (only tested with version 6.0), a term_func
- set via the standard C++ set_terminate() function causes the
- application to abort.
-
- Notes from the MSVC++ manual:
- 1) A term_func() should call exit(), otherwise
- abort() will be called on return to the caller.
- A call to abort() raises SIGABRT and 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(), which
- works by throwing an exception (pthreadVCE or pthreadVSE)
- or by calling longjmp (pthreadVC).
-
- Workaround: avoid using pthread_exit() in C++ applications. Exit
- threads by dropping through the end of the thread routine.

- The problem disappears when /Ob0 is used, i.e. /O2 /Ob0 works OK,
- but if you want to use inlining optimisation you can be much more
- specific about where it's switched off and on by using a pragma.
-
- So the inlining optimisation is interfering with the way that cleanup
- handlers are run. It appears to relate to auto-inlining of class methods
- since this is the only auto inlining that is performed at /O1 optimisation
- (functions with the "inline" qualifier are also inlined, but the problem
- doesn't appear to involve any such functions in the library or testsuite).
-
- In order to confirm the inlining culprit, the following use of pragmas
- eliminate the problem but I don't know how to make it transparent, putting
- it in, say, pthread.h where pthread_cleanup_push defined as a macro.
-
- #pragma inline_depth(0)
- pthread_cleanup_push(handlerFunc, (void *) &arg);
-
- /* ... */
-
- pthread_cleanup_pop(0);
- #pragma inline_depth()
-
- Note the empty () pragma value after the pop macro. This resets depth to the
- default. Or you can specify a non-zero depth here.
-
- The pragma is also needed (and now used) within the library itself wherever
- cleanup handlers are used (condvar.c and rwlock.c).
-
- Use of these pragmas allows compiler optimisations /O1 and /O2 to be
- used for either or both the library and applications.
-
- Experimenting further, I found that wrapping the actual cleanup handler
- function with #pragma auto_inline(off|on) does NOT work.
-
- MSVC6.0 doesn't appear to support the C99 standard's _Pragma directive,
- however, later versions may. This form is embeddable inside #define
- macros, which would be ideal because it would mean that it could be added
- to the push/pop macro definitions in pthread.h and hidden from the
- application programmer.

- Original problem description
- ----------------------------
-
- The cancellation (actually, cleanup-after-cancel) tests fail when using VC
- (professional) optimisation switches (/O1 or /O2) in pthreads library. I
- have not investigated which concrete optimisation technique causes this
- problem (/Og, /Oi, /Ot, /Oy, /Ob1, /Gs, /Gf, /Gy, etc.), but here is a
- summary of builds and corresponding failures:
-
- * pthreads VSE (optimised tests): OK
- * pthreads VCE (optimised tests): Failed "cleanup1" test (runtime)
-
- * pthreads VSE (DLL in CRT, optimised tests): OK
- * pthreads VCE (DLL in CRT, optimised tests): Failed "cleanup1" test
- (runtime)
-
- Please note that while in VSE version of the pthreads library the
- optimisation does not really have any impact on the tests (they pass OK), in
- VCE version addition of optimisation (/O2 in this case) causes the tests to
- fail uniformly - either in "cleanup0" or "cleanup1" test cases.
-
- Please note that all the tests above use default pthreads DLL (no
- optimisations, linked with either static or DLL CRT, based on test type).
- Therefore the problem lies not within the pthreads DLL but within the
- compiled client code (the application using pthreads -> involvement of
- "pthread.h").
-
- I think the message of this section is that usage of VCE version of pthreads
- in applications relying on cancellation/cleanup AND using optimisations for
- creation of production code is highly unreliable for the current version of
- the pthreads library.

- * 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

-
- * implement.h (pthread_t): Renamed to ptw32_thread_t; struct contains

- * 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_post.c (sem_post): 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_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

- [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.

-
-2003-10-15 Alex Blanco <Alex.Blanco at motorola.com>
-
- * sem_init.c (sem_init): Would call CreateSemaphore even if the sema
- struct calloc failed; was not freeing calloced memory if either
- CreateSemaphore or CreateEvent failed.
-
-2003-10-14 Ross Johnson <ross at callisto.canberra.edu.au>
-
- * pthread.h: Add Watcom compiler compatibility. Esssentially just add
- the cdecl attribute to all exposed function prototypes so that Watcom
- generates function call code compatible with non-Watcom built libraries.
- By default, Watcom uses registers to pass function args if possible rather
- than pushing to stack.
- * semaphore.h: Likewise.
- * sched.h: Likewise.
- * pthread_cond_wait.c (ptw32_cond_wait_cleanup): Define with cdecl attribute
- for Watcom compatibility. This routine is called via pthread_cleanup_push so
- it had to match function arg definition.
- * Wmakefile: New makefile for Watcom builds.
-
-2003-09-14 Ross Johnson <rpj at callisto.canberra.edu.au>
-
- * pthread_setschedparam.c (pthread_setschedparam): Attempt to map
- all priority levels between max and min (as returned by
- sched_get_priority_min/max) to reasonable Win32 priority levels - i.e.
- levels between THREAD_PRIORITY_LOWEST/IDLE to THREAD_PRIORITY_LOWEST and
- between THREAD_PRIORITY_HIGHEST/TIME_CRITICAL to THREAD_PRIORITY_HIGHEST
- while others remain unchanged; record specified thread priority level
- for return by pthread_getschedparam.
-
- Note that, previously, specified levels not matching Win32 priority levels
- would silently leave the current thread priority unaltered.
-
- * pthread_getschedparam.c (pthread_getschedparam): Return the priority
- level specified by the latest pthread_setschedparam or pthread_create rather
- than the actual running thread priority as returned by GetThreadPriority - as
- required by POSIX. I.e. temporary or adjusted actual priority levels are not
- returned by this routine.
-
- * pthread_create.c (pthread_create): For priority levels specified via
- pthread attributes, attempt to map all priority levels between max and
- min (as returned by sched_get_priority_min/max) to reasonable Win32
- priority levels; record priority level given via attributes, or
- inherited from parent thread, for later return by pthread_getschedparam.
-
- * ptw32_new.c (ptw32_new): Initialise pthread_t_ sched_priority element.
-
- * pthread_self.c (pthread_self): Set newly created implicit POSIX thread
- sched_priority to Win32 thread's current actual priority. Temporarily
- altered priorities can't be avoided in this case.
-
- * implement.h (struct pthread_t_): Add new sched_priority element.

-
-2003-09-03 Ross Johnson <rpj at callisto.canberra.edu.au>

- of implicit POSIX threads as well.
-
-2003-09-02 Ross Johnson <rpj at callisto.canberra.edu.au>
-
- * pthread_win32_attach_detach_np.c (pthread_win32_thread_detach_np):
- Add comment.
-
- * pthread_exit.c (pthread_exit): Fix to recycle the POSIX thread handle in
- addition to calling user TSD destructors. Move the implicit POSIX thread exit
- handling to ptw32_throw to centralise the logic.
-
- * ptw32_throw.c (ptw32_throw): Implicit POSIX threads have no point
- to jump or throw to, so cleanup and exit the thread here in this case. For
- processes using the C runtime, the exit code will be set to the POSIX
- reason for the throw (i.e. PTHREAD_CANCEL or the value given to pthread_exit).
- Note that pthread_exit() already had similar logic, which has been moved to
- here.
-
- * ptw32_threadDestroy.c (ptw32_threadDestroy): Don't close the Win32 handle
- of implicit POSIX threads - expect this to be done by Win32?
-
-2003-09-01 Ross Johnson <rpj at callisto.canberra.edu.au>
-
- * pthread_self.c (pthread_self): The newly aquired pthread_t must be
- assigned to the reuse stack, not freed, if the routine fails somehow.
-
-2003-08-13 Ross Johnson <rpj at ise.canberra.edu.au>
-
- * pthread_getschedparam.c (pthread_getschedparam): An invalid thread ID
- parameter was returning an incorrect error value; now uses a more exhaustive
- check for validity.
-
- * pthread_setschedparam.c (pthread_setschedparam): Likewise.
-
- * pthread_join.c (pthread_join): Now uses a more exhaustive
- check for validity.
-
- * pthread_detach.c (pthread_detach): Likewise.
-
- * pthread_cancel.c (pthread_cancel): Likewise.
-
- * ptw32_threadDestroy.c (ptw32_threadDestroy): pthread_t structs are
- never freed - push them onto a stack for reuse.
-
- * ptw32_new.c (ptw32_new): Check for reusable pthread_t before dynamically
- allocating new memory for the struct.
-
- * pthread_kill.c (pthread_kill): New file; new routine; takes only a zero
- signal arg so that applications can check the thread arg for validity; checks
- that the underlying Win32 thread HANDLE is valid.
-
- * pthread.h (pthread_kill): Add prototype.
-
- * ptw32_reuse.c (ptw32_threadReusePop): New file; new routine; pop a
- pthread_t off the reuse stack. pthread_t_ structs that have been destroyed, i.e.
- have exited detached or have been joined, are cleaned up and put onto a reuse
- stack. Consequently, thread IDs are no longer freed once calloced. The library
- will attempt to get a struct off this stack before asking the system to alloc
- new memory when creating threads. The stack is guarded by a global mutex.
- (ptw32_threadReusePush): New routine; push a pthread_t onto the reuse stack.
-
- * implement.h (ptw32_threadReusePush): Add new prototype.
- (ptw32_threadReusePop): Likewise.
- (pthread_t): Add new element.
-
- * ptw32_processTerminate.c (ptw32_processTerminate): Delete the thread
- reuse lock; free all thread ID structs on the thread reuse stack.

- * ptw32_processInitialize.c (ptw32_processInitialize): Initialise the
- thread reuse lock.
-
-2003-07-19 Ross Johnson <rpj at ise.canberra.edu.au>

- * pthread_spin_lock.c (pthread_spin_lock): Check for NULL arg.
- * pthread_spin_unlock.c (pthread_spin_unlock): Likewise.
- * pthread_spin_trylock.c (pthread_spin_trylock): Likewise;
- fix incorrect pointer value if lock is dynamically initialised by
- this function.
- * sem_init.c (sem_init): Initialise sem_t value to quell compiler warning.
- * sem_destroy.c (sem_destroy): Likewise.
- * ptw32_threadStart.c (non-MSVC code sections): Include <exception> rather
- than old-style <new.h>; fix all std:: namespace entities such as
- std::terminate_handler instances and associated methods.
- * ptw32_callUserDestroyRoutines.c (non-MSVC code sections): Likewise.
-
-2003-06-24 Piet van Bruggen <pietvb at newbridges.nl>

-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

-
-2003-05-15 Steven Reddie <Steven.Reddie at ca.com>
-
- * pthread_win32_attach_detach_np.c (pthread_win32_process_detach_np):
- NULLify ptw32_selfThreadKey after the thread is destroyed, otherwise
- destructors calling pthreads routines might resurrect it again, creating
- memory leaks. Call the underlying Win32 Tls routine directly rather than
- pthread_setspecific().
- (pthread_win32_thread_detach_np): Likewise.
-
-2003-05-14 Viv <vcotirlea at hotmail.com>
-
- * pthread.dsp: Change /MT compile flag to /MD.
-
-2003-03-04 Alexander Terekhov <TEREKHOV at de.ibm.com>
-
- * pthread_mutex_timedlock.c (pthread_mutex_timedlock): Fix failure to
- set ownership of mutex on second grab after abstime timeout.
- - bug reported by Robert Strycek <strycek at posam.sk>
-
-2002-12-17 Thomas Pfaff <tpfaff at gmx.net>
-
- * pthread_mutex_lock.c (ptw32_semwait): New static routine to provide
- a non-cancelable sem_wait() function. This is consistent with the
- way that pthread_mutex_timedlock.c does it.
- (pthread_mutex_lock): Use ptw32_semwait() instead of sem_wait().
-
-2002-12-11 Thomas Pfaff <tpfaff at gmx.net>
-
- * pthread_mutex_trylock.c: Should return EBUSY rather than EDEADLK.
- * pthread_mutex_destroy.c: Remove redundant ownership test (the
- trylock call does this for us); do not destroy a recursively locked
- mutex.
-
-2002-09-20 Michael Johnson <michaelj at maine.rr.com>
-
- * pthread_cond_destroy.c (pthread_cond_destroy):
- When two different threads exist, and one is attempting to
- destroy a condition variable while the other is attempting to
- initialize a condition variable that was created with
- PTHREAD_COND_INITIALIZER, a deadlock can occur. Shrink
- the ptw32_cond_list_lock critical section to fix it.
-
-2002-07-31 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * ptw32_threadStart.c (ptw32_threadStart): Thread cancelLock
- destruction moved to ptw32_threadDestroy().
-
- * ptw32_threadDestroy.c (ptw32_threadDestroy): Destroy
- the thread's cancelLock. Moved here from ptw32_threadStart.c
- to cleanup implicit threads as well.
-
-2002-07-30 Alexander Terekhov <TEREKHOV at de.ibm.com>
-
- * pthread_cond_wait.c (ptw32_cond_wait_cleanup):
- Remove code designed to avoid/prevent spurious wakeup
- problems. It is believed that the sem_timedwait() call
- is consuming a CV signal that it shouldn't and this is
- breaking the avoidance logic.
-
-2002-07-30 Ross Johnson <rpj at ise.canberra.edu.au>
-
- * sem_timedwait.c (sem_timedwait): Tighten checks for
- unreasonable abstime values - that would result in
- unexpected timeout values.
-
- * w32_CancelableWait.c (ptw32_cancelable_wait):
- Tighten up return value checking and add comments.
-
-
-2002-06-08 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * sem_getvalue.c (sem_getvalue): Now returns a value for the
- NEED_SEM version (i.e. earlier versions of WinCE).
-
-
-2002-06-04 Rob Fanner <rfanner at stonethree.com>
-
- * sem_getvalue.c (sem_getvalue): The Johnson M. Hart
- approach didn't work - we are forced to take an
- intrusive approach. We try to decrement the sema
- and then immediately release it again to get the
- value. There is a small probability that this may
- block other threads, but only momentarily.
-
-2002-06-03 Ross Johnson <rpj at ise.canberra.edu.au>
-
- * sem_init.c (sem_init): Initialise Win32 semaphores
- to _POSIX_SEM_VALUE_MAX (which this implementation
- defines in pthread.h) so that sem_getvalue() can use
- the trick described in the comments in sem_getvalue().
- * pthread.h (_POSIX_SEM_VALUE_MAX): Defined.
- (_POSIX_SEM_NSEMS_MAX): Defined - not used but may be
- useful for source code portability.
-
-2002-06-03 Rob Fanner <rfanner at stonethree.com>
-
- * sem_getvalue.c (sem_getvalue): Did not work on NT.
- Use approach suggested by Johnson M. Hart in his book
- "Win32 System Programming".
-
-2002-02-28 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * errno.c: Compiler directive was incorrectly including code.
- * pthread.h: Conditionally added some #defines from config.h
- needed when not building the library. e.g. NEED_ERRNO, NEED_SEM.
- (PTW32_DLLPORT): Now only defined if _DLL defined.
- (_errno): Compiler directive was incorrectly including prototype.
- * sched.h: Conditionally added some #defines from config.h
- needed when not building the library.
- * semaphore.h: Replace an instance of NEED_SEM that should
- have been NEED_ERRNO. This change currently has nil effect.
-
- * GNUmakefile: Correct some recent changes.
-
- * Makefile: Add rule to generate pre-processor output.
-
-2002-02-23 Ross Johnson <rpj at setup1.ise.canberra.edu.au>

- * pthread_rwlock_timedwrlock.c: New - untested.
-
- * Testsuite passed (except known MSVC++ problems)
-
- * pthread_cond_destroy.c: Expand the time change
- critical section to solve deadlock problem.
-
- * pthread.c: Add all remaining C modules.
- * pthread.h: Use dllexport/dllimport attributes on functions
- to avoid using pthread.def.
- * sched.h: Likewise.
- * semaphore.h: Likewise.
- * GNUmakefile: Add new targets for single translation
- unit build to maximise inlining potential; generate
- pthread.def automatically.

-
-2002-02-20 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * pthread_cond_destroy.c (pthread_cond_destroy):
- Enter the time change critical section earlier.
-
-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.
- * ptw32_processInitialize (ptw32_cond_list_cs): Initialize.
- * ptw32_processTerminate (ptw32_cond_list_cs): Delete.
-
-
- * Reduce executable size.
- -----------------------
- When linking with the static library, only those
- routines actually called, either directly or indirectly

- -----------------------------
- When the appropriate symbols are defined, the headers

-
- * cancel.c: Rearranged some code and introduced checks
- to disable cancelation at the start of a thread's cancelation
- run to prevent double cancelation. The main problem
- arises if a thread is canceling and then receives a subsequent
- async cancel request.
- * private.c: Likewise.
- * condvar.c: Place pragmas around cleanup_push/pop to turn
- off inline optimisation (/Obn where n>0 - MSVC only). Various
- optimisation switches in MSVC turn this on, which interferes with
- the way that cleanup handlers are run in C++ EH and SEH
- code. Application code compiled with inline optimisation must

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

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

-
- * mutex.c (pthread_mutex_trylock): use
- ptw32_interlocked_compare_exchange function pointer
- rather than ptw32_InterlockedCompareExchange() directly
- to retain portability to non-iX86 processors,
- e.g. WinCE etc. The pointer will point to the native

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

- (pthread_attr_getscope): Return stored value.
- * implement.h (pthread_attr_t_): Add new scope element.
- * ANNOUNCE: Fix out of date comment next to

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

-
-2001-10-26 prionx@juno.com
-
- * semaphore.c (sem_init): Fix typo and missing bracket
- in conditionally compiled code. Only older versions of
- WinCE require this code, hence it doesn't normally get
- tested; somehow when sem_t reverted to an opaque struct
- the calloc NULL check was left in the conditionally included
- section.

-
- * attr.c (pthread_attr_setstacksize): Quell warning
- from LCC by conditionally compiling the stacksize
- validity check. LCC correctly warns that the condition
- (stacksize < PTHREAD_STACK_MIN) is suspicious
- because STACK_MIN is 0 and stacksize is of type
- size_t (or unsigned int).
-
-2001-10-17 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * barrier.c: Move _LONG and _LPLONG defines into

- * spin.c: Likewise; ptw32_interlocked_compare_exchange used
- in place of InterlockedCompareExchange directly.
- * global.c (ptw32_interlocked_compare_exchange): Add
- prototype for this new routine pointer to be used when
- InterlockedCompareExchange isn't supported by Windows.
- * nonportable.c (pthread_win32_process_attach_np): Check for
- support of InterlockedCompareExchange in kernel32 and assign its
- address to ptw32_interlocked_compare_exchange if it exists, or
- our own ix86 specific implementation ptw32_InterlockedCompareExchange.
- *private.c (ptw32_InterlockedCompareExchange): An
- implementation of InterlockedCompareExchange() which is
- specific to ix86; written directly in assembler for either
- MSVC or GNU C; needed because Windows 95 doesn't support
- InterlockedCompareExchange().
-
- * sched.c (sched_get_priority_min): Extend to return
- THREAD_PRIORITY_IDLE.

-
-2001-10-12 Ross Johnson <rpj at setup1.ise.canberra.edu.au>

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

- 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>

-
- * 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

- * global.c (pthread_count): Moved from dll.c.
- * nonportable.c (pthread_win32_process_attach_np):

- * create.c: Likewise.
- * pthread.h: Likewise.
- * misc.c: Likewise.
- * exit.c: 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.

- 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.

- (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.

-
-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.

-
- * 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.

- 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.

- cleared by TlsGetValue() call in
- pthread_getspecific()
-
-2000-09-20 Arthur Kantor <akantor at bexusa.com>
-
- * mutex.c (pthread_mutex_lock): Record the owner
- of the mutex. This requires also keeping count of
- recursive locks ourselves rather than leaving it
- to Win32 since we need to know when to NULL the
- thread owner when the mutex is unlocked.
- (pthread_mutex_trylock): Likewise.
- (pthread_mutex_unlock): Check that the calling
- thread owns the mutex, decrement the recursive
- lock count, and NULL the owner if zero. Return
- EPERM if the mutex is owned by another thread.
- * implement.h (pthread_mutex_t_): Add ownerThread
- and lockCount members.
-
-2000-09-13 Jef Gearhart <jgearhart at tpssys.com>
-
- * mutex.c (pthread_mutex_init): Call
- TryEnterCriticalSection through the pointer
- rather than directly so that the dll can load
- on Windows versions that can't resolve the
- function, eg. Windows 95
-
-2000-09-09 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * pthread.h (ctime_r): Fix arg.
-
-2000-09-08 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * GNUmakefile(_WIN32_WINNT=0x400): Define in CFLAGS;
- doesn't seem to be needed though.
-
- * cancel.c (pthread_cancel): Must get "self" through
- calling pthread_self() which will ensure a POSIX thread
- struct is built for non-POSIX threads; return an error
- if this fails
- - Ollie Leahy <ollie at mpt.ie>
- (pthread_setcancelstate): Likewise.
- (pthread_setcanceltype): Likewise.

- Needed to be forward declared unconditionally.
-
-2000-09-06 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * cancel.c (pthread_cancel): If called from the main
- thread "self" would be NULL; get "self" via pthread_self()
- instead of directly from TLS so that an implicit
- pthread object is created.
-
- * misc.c (pthread_equal): Strengthen test for NULLs.
-
-2000-09-02 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * condvar.c (ptw32_cond_wait_cleanup): Ensure that all
- waking threads check if they are the last, and notify
- the broadcaster if so - even if an error occurs in the
- waiter.
-
- * semaphore.c (_decrease_semaphore): Should be
- a call to ptw32_decrease_semaphore.
- (_increase_semaphore): Should be a call to
- ptw32_increase_semaphore.
-
- * misc.c (ptw32_cancelable_wait): Renamed from
- CancelableWait.
- * rwlock.c (_rwlock_check*): Renamed to
- ptw32_rwlock_check*.
- * mutex.c (_mutex_check*): Renamed to ptw32_mutex_check*.

-
-2000-08-18 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-

- held; invalidate the mutex as early as possible to avoid
- contention; not perfect - FIXME!
-
- * rwlock.c (pthread_rwlock_init): Remove redundant assignment
- to "rw".
- (pthread_rwlock_destroy): Invalidate the rwlock before
- freeing up any of it's resources - to avoid contention.
-
- * private.c (ptw32_tkAssocCreate): Change assoc->lock
- to use a dynamically initialised mutex - only consumes
- a W32 mutex or critical section when first used,
- not before.
-
- * mutex.c (pthread_mutex_init): Remove redundant assignment
- to "mx".
- (pthread_mutexattr_destroy): Set attribute to NULL
- before freeing it's memory - to avoid contention.
-
- * implement.h (PTW32_EPS_CANCEL/PTW32_EPS_EXIT):
- Must be defined for all compilers - used as generic
- exception selectors by ptw32_throw().
-
- * Several: Fix typos from scripted edit session
- yesterday.
-
- * nonportable.c (pthread_mutexattr_setforcecs_np):
- Moved this function from mutex.c.
- (pthread_getw32threadhandle_np): New function to
- return the win32 thread handle that the POSIX
- thread is using.
- * mutex.c (pthread_mutexattr_setforcecs_np):
- Moved to new file "nonportable.c".
-
- * pthread.h (PTW32_BUILD): Only redefine __except
- and catch compiler keywords if we aren't building
- the library (ie. PTW32_BUILD is not defined) -
- this is safer than defining and then undefining
- if not building the library.
- * implement.h: Remove __except and catch undefines.
- * Makefile (CFLAGS): Define PTW32_BUILD.
- * GNUmakefile (CFLAGS): Define PTW32_BUILD.

- (pthread_testcancel): Ditto.
- (pthread_cancel): Ditto.
- * misc.c (CancelableWait): Ditto.
- * exit.c (pthread_exit): Ditto.
- * All applicable: Change PTW32_ prefix to
- PTW32_ prefix to remove leading underscores
- from private library identifiers.
-
-2000-08-17 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * All applicable: Change _pthread_ prefix to
- ptw32_ prefix to remove leading underscores
- from private library identifiers (single
- and double leading underscores are reserved in the
- ANSI C standard for compiler implementations).
-
- * tsd.c (pthread_create_key): Initialise temporary
- key before returning it's address to avoid race
- conditions.
-
-2000-08-13 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * errno.c: Add _MD precompile condition; thus far
- had no effect when using /MD compile option but I
- thnk it should be there.
-
- * exit.c: Add __cplusplus to various #if lines;
- was compiling SEH code even when VC++ had
- C++ compile options.
-
- * private.c: ditto.
-
- * create.c (pthread_create): Add PT_STDCALL macro to
- function pointer arg in _beginthread().
-
- * pthread.h: PT_STDCALL really does need to be defined
- in both this and impliment.h; don't set it to __cdecl
- - this macro is only used to extend function pointer
- casting for functions that will be passed as parameters.
- (~PThreadCleanup): add cast and group expression.
- (_errno): Add _MD compile conditional.
- (PtW32NoCatchWarn): Change pragma message.
-
- * implement.h: Move and change PT_STDCALL define.
-
- * need_errno.h: Add _MD to compilation conditional.
-
- * GNUmakefile: Substantial rewrite for new naming
- convention; set for nil optimisation (turn it up
- when we have a working library build; add target
- "fake.a" to build a libpthreadw32.a from the VC++
- built DLL pthreadVCE.dll.
-
- * pthread.def (LIBRARY): Don't specify in the .def
- file - it is specified on the linker command line
- since we now use the same .def file for variously
- named .dlls.
-
- * Makefile: Substantial rewrite for new naming
- convention; default nmake target only issues a
- help message; run nmake with specific target
- corresponding to the EH scheme being used.
-
- * README: Update information; add naming convention
- explanation.
-
- * ANNOUNCE: Update information.
-
-2000-08-12 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * pthread.h: Add compile-time message when using
- MSC_VER compiler and C++ EH to warn application
- programmers to use PtW32Catch instead of catch(...)
- if they want cancelation and pthread_exit to work.
-
- * implement.h: Remove #include <semaphore.h>; we
- use our own local semaphore.h.
-
-2000-08-10 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * cleanup.c (pthread_pop_cleanup): Remove _pthread
- prefix from __except and catch keywords; implement.h
- now simply undefines ptw32__except and
- ptw32_catch if defined; VC++ was not textually
- substituting ptw32_catch etc back to catch as
- it was redefined; the reason for using the prefixed
- version was to make it clear that it was not using
- the pthread.h redefined catch keyword.
-
- * private.c (ptw32_threadStart): Ditto.
- (ptw32_callUserDestroyRoutines): Ditto.
-
- * implement.h (ptw32__except): Remove #define.
- (ptw32_catch): Remove #define.
-
- * GNUmakefile (pthread.a): New target to build
- libpthread32.a from pthread.dll using dlltool.
-
- * buildlib.bat: Duplicate cl commands with args to
- build C++ EH version of pthread.dll; use of .bat
- files is redundant now that nmake compatible
- Makefile is included; used as a kludge only now.
-
- * Makefile: Localise some macros and fix up the clean:
- target to extend it and work properly.
-
- * CONTRIBUTORS: Add contributors.
-
- * ANNOUNCE: Updated.
-
- * README: Updated.
-
-2000-08-06 Ross Johnson <rpj at special.ise.canberra.edu.au>

- * pthread.h: Remove #warning - VC++ doesn't accept it.
-
-2000-08-05 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * pthread.h (PtW32CatchAll): Add macro. When compiling
- applications using VC++ with C++ EH rather than SEH
- 'PtW32CatchAll' must be used in place of any 'catch( ... )'
- if the application wants pthread cancelation or
- pthread_exit() to work.
-
-2000-08-03 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * pthread.h: Add a base class ptw32_exception for

- (sched_get_priority_min): Ditto.
-
-2000-07-25 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * create.c (pthread_create): Force new threads to wait until
- pthread_create has the new thread's handle; we also retain
- a local copy of the handle for internal use until
- pthread_create returns.
-
- * private.c (ptw32_threadStart): Initialise ei[].
- (ptw32_threadStart): When beginthread is used to start the
- thread, force waiting until the creator thread had the
- thread handle.
-
- * cancel.c (ptw32_cancel_thread): Include context switch
- code for defined(_X86_) environments in addition to _M_IX86.
-
- * rwlock.c (pthread_rwlock_destroy): Assignment changed
- to avoid compiler warning.
-
- * private.c (ptw32_get_exception_services_code): Cast
- NULL return value to avoid compiler warning.
-
- * cleanup.c (pthread_pop_cleanup): Initialise "cleanup" variable
- to avoid compiler warnings.
-
- * misc.c (ptw32_new): Change "new" variable to "t" to avoid
- confusion with the C++ keyword of the same name.
-
- * condvar.c (cond_wait_cleanup): Initialise lastWaiter variable.
- (cond_timedwait): Remove unused local variables. to avoid
- compiler warnings.
-
- * dll.c (dllMain): Remove 2000-07-21 change - problem
- appears to be in pthread_create().
-
-2000-07-22 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * tsd.c (pthread_key_create): If a destructor was given
- and the pthread_mutex_init failed, then would try to
- reference a NULL pointer (*key); eliminate this section of
- code by using a dynamically initialised mutex
- (PTHREAD_MUTEX_INITIALIZER).
-
- * tsd.c (pthread_setspecific): Return an error if
- unable to set the value; simplify cryptic conditional.
-
- * tsd.c (pthread_key_delete): Locking threadsLock relied
- on mutex_lock returning an error if the key has no destructor.
- ThreadsLock is only initialised if the key has a destructor.
- Making this mutex a static could reduce the number of mutexes
- used by an application since it is actually created only at
- first use and it's often destroyed soon after.
-
-2000-07-22 Ross Johnson <rpj at special.ise.canberra.edu.au>
-
- * FAQ: Added Q5 and Q6.
-
-2000-07-21 David Baggett <dmb at itasoftware.com>
-
- * dll.c: Include resource leakage work-around. This is a
- partial FIXME which doesn't stop all leakage. The real
- problem needs to be found and fixed.
-
-2000-07-21 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
-
- * create.c (pthread_create): Set threadH to 0 (zero)
- everywhere. Some assignments were using NULL. Maybe
- it should be NULL everywhere - need to check. (I know
- they are nearly always the same thing - but not by
- definition.)
-
- * misc.c (pthread_self): Try to catch NULL thread handles
- at the point where they might be generated, even though
- they should always be valid at this point.

-
-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>

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

Win32 semaphores are + used instead of events in order to support efficient multiple posting. + If the whole modify/release isn't atomic, a race between + sem_timedwait() and sem_post() could result in a release when there is + no waiting semaphore, which would cause too many threads to proceed. + * sem_wait.c (sem_wait): Use new 'lock'element. + * sem_timedwait.c (sem_timedwait): Likewise. + * sem_trywait.c (sem_trywait): Likewise. + * sem_post.c (sem_post): Likewise. + * sem_post_multiple.c (sem_post_multiple): Likewise. + * sem_getvalue.c (sem_getvalue): Likewise. + * ptw32_semwait.c (ptw32_semwait): Likewise. + * sem_destroy.c (sem_destroy): Likewise; also tightened the conditions + for semaphore destruction; in particular, a semaphore will not be + destroyed if it has waiters. + * sem_timedwait.c (sem_timedwait): Added cancel cleanup handler to + restore sema value when cancelled. + * sem_wait.c (sem_wait): Likewise. + +2004-10-21 Ross Johnson <rpj at callisto.canberra.edu.au> + + * pthread_mutex_unlock.c (pthread_mutex_unlock): Must use PulseEvent() + rather than SetEvent() to reset the event if there are no waiters. + +2004-10-19 Ross Johnson <rpj at callisto.canberra.edu.au> + + * sem_init.c (sem_init): New semaphore model based on the same idea + as mutexes, i.e. user space interlocked check to avoid + unnecessarily entering kernel space. Wraps the Win32 semaphore and + keeps it's own counter. Although the motivation to do this has existed + for a long time, credit goes to Alexander Terekhov for providing + the logic. I have deviated slightly from AT's logic to add the waiters + count, which has made the code more complicated by adding cancelation + cleanup. This also appears to have broken the VCE (C++ EH) version of + the library (the same problem as previously reported - see BUGS #2), + only apparently not fixable using the usual workaround, nor by turning + all optimisation off. The GCE version works fine, so it is presumed to + be a bug in MSVC++ 6.0. The cancelation exception is thrown and caught + correctly, but the cleanup class destructor is never called.

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

-# The 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.
-#
-# 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 like Solaris (this is the default).
-# Set to some other +ve value to emulate smaller word size types (i.e. will
-# wrap sooner). This might be useful to emulate some embedded systems.

-
-General
--------
-
-This release is a backport of features and bug fixes new in
-release 2.3.0. See earlier notes under Release 1.4.0/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.

--------------
-(2005-03-16)
-
-General
--------
-
-Version 2.0.0 is being released and version 1.4.0 back-ports the
-functionality included in that release. In future, bug fixes
-will be back-ported if possible and where appropriate, however,
-this will be at the maintainer's descretion. New features will
-not generally be back-ported, although some may if they
-provide major improvements in compatibility with the standard.
-
-This is intended as a courtesy to application developers, but as
-time moves on, the imperative will fade.
-
-The package naming has changed, replacing the snapshot date with
-the version number + descriptive information. E.g. this
-release is "pthreads-w32-1-4-0-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.

-
-Bug fixes
----------

-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.

-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.

+RELEASE 1.7.0 +------------- +(2005-04-12) + +General +------- + +This release is a backport of features and bug fixes new in +release 2.3.0. See earlier notes under Release 1.4.0/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 1.6.0 +------------- +(2005-04-04) + +General +------- + +This release is a backport of features and bug fixes new in +release 2.2.0. See earlier notes under Release 1.4.0/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 specific conditions on +distributing software that has been statically linked with this library. + +Bugs fixed +---------- + +* Fix integer overrun error in sem_timedwait(). +Kevin Lussier + +* Fix preprocessor directives for static linking. +Dimitar Panayotov + + +RELEASE 1.5.0 +------------- +(2005-03-16) + +General +------- + +This release is a backport of features and bug fixes new in +release 2.1.0. See earlier notes under Release 1.4.0/General. + +Bugs fixed +---------- + +* Reverse change to pthread_setcancelstate() made in 1.4.0. + + +RELEASE 1.4.0 +------------- +(2005-03-16) + +General +------- + +Version 2.0.0 is being released and version 1.4.0 back-ports the +functionality included in that release. In future, bug fixes +will be back-ported if possible and where appropriate, however, +this will be at the maintainer's descretion. New features will +not generally be back-ported, although some may if they +provide major improvements in compatibility with the standard. + +This is intended as a courtesy to application developers, but as +time moves on, the imperative will fade. + +The package naming has changed, replacing the snapshot date with +the version number + descriptive information. E.g. this +release is "pthreads-w32-1-4-0-release". + +Bugs fixed +---------- + +* pthread_setcancelstate() no longer checks for a pending +async cancel event if the library is using alertable async +cancel. See the README file (Prerequisites section) for info +on adding alertable async cancelation. + +New features +------------ + +* pthread_once() now supports init_routine cancellability. + +New tests +--------- + +* Agressively test pthread_once() init_routine cancellability. + + +SNAPSHOT 2005-03-08 +------------------- +Version 1.3.0 + +Bug reports (fixed) +------------------- + +* Implicitly created threads leave Win32 handles behind after exiting. +- Dmitrii Semii + +* pthread_once() starvation problem. +- Gottlob Frege + +New tests +--------- + +* More intense testing of pthread_once(). + + +SNAPSHOT 2005-01-25 +------------------- +Version 1.2.0 + +Bug fixes +--------- + +* Attempted acquisition of a recursive mutex could cause waiting threads +to not be woken when the mutex was released. +- Ralf Kubis <RKubis at mc.com> + +* Various package omissions have been fixed. + + +SNAPSHOT 2005-01-03 +------------------- +Version 1.1.0 + +Bug fixes +--------- + +* Unlocking recursive or errorcheck mutexes would sometimes +unexpectedly return an EPERM error (bug introduced in +snapshot-2004-11-03). +- Konstantin Voronkov <beowinkle at yahoo.com> + + +SNAPSHOT 2004-11-22 +------------------- +Version 1.0.0 + +This snapshot primarily fixes the condvar bug introduced in +snapshot-2004-11-03. DLL versioning has also been included to allow +applications to runtime check the Microsoft compatible DLL version +information, and to extend the DLL naming system for ABI and major +(non-backward compatible) API changes. See the README file for details. + +Bug fixes +--------- + +* Condition variables no longer deadlock (bug introduced in +snapshot-2004-11-03). +- Alexander Kotliarov and Nicolas at saintmac + +* DLL naming extended to avoid 'DLL hell' in the future, and to +accommodate the ABI change introduced in snapshot-2004-11-03. Snapshot +2004-11-03 will be removed from FTP sites. + +New features +------------ + +* A Microsoft-style version resource has been added to the DLL for +applications that wish to check DLL compatibility at runtime. + +* Pthreads-win32 DLL naming has been extended to allow incompatible DLL +versions to co-exist in the same filesystem. See the README file for details, +but briefly: while the version information inside the DLL will change with +each release from now on, the DLL version names will only change if the new +DLL is not backward compatible with older applications. + +The versioning scheme has been borrowed from GNU Libtool, and the DLL +naming scheme is from Cygwin. Provided the Libtool-style numbering rules are +honoured, the Cygwin DLL naming scheme automatcally ensures that DLL name +changes are minimal and that applications will not load an incompatible +pthreads-win32 DLL. + +Those who use the pre-built DLLs will find that the DLL/LIB names have a new +suffix (1) in this snapshot. E.g. pthreadVC1.dll etc. + +* The POSIX thread ID reuse uniqueness feature introduced in the last snapshot +has been kept as default, but the behaviour can now be controlled when the DLL +is built to effectively switch it off. This makes the library much more +sensitive to applications that assume that POSIX thread IDs are unique, i.e. +are not strictly compliant with POSIX. See the PTW32_THREAD_ID_REUSE_INCREMENT +macro comments in config.h for details. + +Other changes +------------- +Certain POSIX macros have changed. + +These changes are intended to conform to the Single Unix Specification version 3, +which states that, if set to 0 (zero) or not defined, then applications may use +sysconf() to determine their values at runtime. Pthreads-win32 does not +implement sysconf(). + +The following macros are no longer undefined, but defined and set to -1 +(not implemented): + + _POSIX_THREAD_ATTR_STACKADDR + _POSIX_THREAD_PRIO_INHERIT + _POSIX_THREAD_PRIO_PROTECT + _POSIX_THREAD_PROCESS_SHARED + +The following macros are defined and set to 200112L (implemented): + + _POSIX_THREADS + _POSIX_THREAD_SAFE_FUNCTIONS + _POSIX_THREAD_ATTR_STACKSIZE + _POSIX_THREAD_PRIORITY_SCHEDULING + _POSIX_SEMAPHORES + _POSIX_READER_WRITER_LOCKS + _POSIX_SPIN_LOCKS + _POSIX_BARRIERS + +The following macros are defined and set to appropriate values: + + _POSIX_THREAD_THREADS_MAX + _POSIX_SEM_VALUE_MAX + _POSIX_SEM_NSEMS_MAX + PTHREAD_DESTRUCTOR_ITERATIONS + PTHREAD_KEYS_MAX + PTHREAD_STACK_MIN + PTHREAD_THREADS_MAX + + +SNAPSHOT 2004-11-03 +------------------- + +DLLs produced from this snapshot cannot be used with older applications without +recompiling the application, due to a change to pthread_t to provide unique POSIX +thread IDs. + +Although this snapshot passes the extended test suite, many of the changes are +fairly major, and some applications may show different behaviour than previously, +so adopt with care. Hopefully, any changed behaviour will be due to the library +being better at it's job, not worse. + +Bug fixes +--------- + +* pthread_create() no longer accepts NULL as the thread reference arg. +A segfault (memory access fault) will result, and no thread will be +created. + +* pthread_barrier_wait() no longer acts as a cancelation point. + +* Fix potential race condition in pthread_once() +- Tristan Savatier <tristan at mpegtv.com> + +* Changes to pthread_cond_destroy() exposed some coding weaknesses in several +test suite mini-apps because pthread_cond_destroy() now returns EBUSY if the CV +is still in use. + +New features +------------ + +* Added for compatibility: +PTHREAD_RECURSIVE_MUTEX_INITIALIZER, +PTHREAD_ERRORCHECK_MUTEX_INITIALIZER, +PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP, +PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP + +* Initial support for Digital Mars compiler +- Anuj Goyal <anuj.goyal at gmail.com> + +* Faster Mutexes. These have been been rewritten following a model provided by +Alexander Terekhov that reduces kernel space checks, and eliminates some additional +critical sections used to manage a race between timedlock expiration and unlock. +Please be aware that the new mutexes do not enforce strict absolute FIFO scheduling +of mutexes, however any out-of-order lock acquisition should be very rare. + +* Faster semaphores. Following a similar model to mutexes above, these have been +rewritten to use preliminary users space checks. + +* sem_getvalue() now returns the number of waiters. + +* The POSIX thread ID now has much stronger uniqueness characteristics. The library +garrantees not to reuse the same thread ID for at least 2^(wordsize) thread +destruction/creation cycles. + +New tests +--------- + +* semaphore4.c: Tests cancelation of the new sem_wait(). + +* semaphore4t.c: Likewise for sem_timedwait(). + +* rwlock8.c: Tests and times the slow execution paths of r/w locks, and the CVs, +mutexes, and semaphores that they're built on. + + +SNAPSHOT 2004-05-16 +------------------- + +Attempt to add Watcom to the list of compilers that can build the library. +This failed in the end due to it's non-thread-aware errno. The library +builds but the test suite fails. See README.Watcom for more details. + +Bug fixes +--------- +* Bug and memory leak in sem_init() +- Alex Blanco <Alex.Blanco at motorola.com> + +* ptw32_getprocessors() now returns CPU count of 1 for WinCE. +- James Ewing <james.ewing at sveasoft.com> + +* pthread_cond_wait() could be canceled at a point where it should not +be cancelable. Fixed. +- Alexander Terekhov <TEREKHOV at de.ibm.com> + +* sem_timedwait() had an incorrect timeout calculation. +- Philippe Di Cristo <philipped at voicebox.com> + +* Fix a memory leak left behind after threads are destroyed. +- P. van Bruggen <pietvb at newbridges.nl> + +New features +------------ +* Ported to AMD64. +- Makoto Kato <raven at oldskool.jp> + +* True pre-emptive asynchronous cancelation of threads.

See the README.txt file inside +the package for installation details. + +Note: If you don't use async cancelation in your application, or don't need +to cancel threads that are blocked on system resources such as network I/O, +then the default non-preemptive async cancelation is probably good enough. +However, pthreads-win32 auto-detects the availability of these components +at run-time, so you don't need to rebuild the library from source if you +change your mind later. + +All of the advice available in books and elsewhere on the undesirability +of using async cancelation in any application still stands, but this +feature is a welcome addition with respect to the library's conformance to +the POSIX standard. + +SNAPSHOT 2003-09-18 +------------------- + +Cleanup of thread priority management. In particular, setting of thread +priority now attempts to map invalid Win32 values within the range returned +by sched_get_priority_min/max() to useful values. See README.NONPORTABLE +under "Thread priority". + +Bug fixes +--------- +* pthread_getschedparam() now returns the priority given by the most recent +call to pthread_setschedparam() or established by pthread_create(), as +required by the standard. Previously, pthread_getschedparam() incorrectly +returned the running thread priority at the time of the call, which may have +been adjusted or temporarily promoted/demoted. + +* sched_get_priority_min() and sched_get_priority_max() now return -1 on error +and set errno. Previously, they incorrectly returned the error value directly. + + +SNAPSHOT 2003-09-04 +------------------- + +Bug fixes +--------- +* ptw32_cancelableWait() now allows cancelation of waiting implicit POSIX +threads. + +New test +-------- +* cancel8.c tests cancelation of Win32 threads waiting at a POSIX cancelation +point. + + +SNAPSHOT 2003-09-03 +------------------- + +Bug fixes +--------- +* pthread_self() would free the newly created implicit POSIX thread handle if +DuplicateHandle failed instead of recycle it (very unlikely). + +* pthread_exit() was neither freeing nor recycling the POSIX thread struct +for implicit POSIX threads. + +New feature - Cancelation of/by Win32 (non-POSIX) threads +--------------------------------------------------------- +Since John Bossom's original implementation, the library has allowed non-POSIX +initialised threads (Win32 threads) to call pthreads-win32 routines and +therefore interact with POSIX threads. This is done by creating an on-the-fly +POSIX thread ID for the Win32 thread that, once created, allows fully +reciprical interaction. This did not extend to thread cancelation (async or +deferred). Now it does. + +Any thread can be canceled by any other thread (Win32 or POSIX) if the former +thread's POSIX pthread_t value is known. It's TSD destructors and POSIX +cleanup handlers will be run before the thread exits with an exit code of +PTHREAD_CANCELED (retrieved with GetExitCodeThread()). + +This allows a Win32 thread to, for example, call POSIX CV routines in the same way +that POSIX threads would/should, with pthread_cond_wait() cancelability and +cleanup handlers (pthread_cond_wait() is a POSIX cancelation point). + +By adding cancelation, Win32 threads should now be able to call all POSIX +threads routines that make sense including semaphores, mutexes, condition +variables, read/write locks, barriers, spinlocks, tsd, cleanup push/pop, +cancelation, pthread_exit, scheduling, etc. + +Note that these on-the-fly 'implicit' POSIX thread IDs are initialised as detached +(not joinable) with deferred cancelation type. The POSIX thread ID will be created +automatically by any POSIX routines that need a POSIX handle (unless the routine +needs a pthread_t as a parameter of course). A Win32 thread can discover it's own +POSIX thread ID by calling pthread_self(), which will create the handle if +necessary and return the pthread_t value. + +New tests +--------- +Test the above new feature. + + +SNAPSHOT 2003-08-19 +------------------- + +This snapshot fixes some accidental corruption to new test case sources. +There are no changes to the library source code. + + +SNAPSHOT 2003-08-15 +------------------- + +Bug fixes +--------- + +* pthread.dsp now uses correct compile flags (/MD). +- Viv <vcotirlea@hotmail.com> + +* pthread_win32_process_detach_np() fixed memory leak. +- Steven Reddie <Steven.Reddie@ca.com> + +* pthread_mutex_destroy() fixed incorrect return code. +- Nicolas Barry <boozai@yahoo.com> + +* pthread_spin_destroy() fixed memory leak. +- Piet van Bruggen <pietvb@newbridges.nl> + +* Various changes to tighten arg checking, and to work with later versions of +MinGW32 and MsysDTK. + +* pthread_getschedparam() etc, fixed dangerous thread validity checking. +- Nicolas Barry <boozai@yahoo.com> + +* POSIX thread handles are now reused and their memory is not freed on thread exit. +This allows for stronger thread validity checking. + +New standard routine +-------------------- + +* pthread_kill() added to provide thread validity checking to applications. +It does not accept any non zero values for the signal arg. + +New test cases +-------------- + +* New test cases to confirm validity checking, pthread_kill(), and thread reuse. + + +SNAPSHOT 2003-05-10 +------------------- + +Bug fixes +--------- + +* pthread_mutex_trylock() now returns correct error values. +pthread_mutex_destroy() will no longer destroy a recursively locked mutex. +pthread_mutex_lock() is no longer inadvertantly behaving as a cancelation point. +- Thomas Pfaff <tpfaff@gmx.net> + +* pthread_mutex_timedlock() no longer occasionally sets incorrect mutex +ownership, causing deadlocks in some applications. +- Robert Strycek <strycek@posam.sk> and Alexander Terekhov <TEREKHOV@de.ibm.com> + + +SNAPSHOT 2002-11-04 +------------------- + +Bug fixes +--------- + +* sem_getvalue() now returns the correct value under Win NT and WinCE. +- Rob Fanner <rfanner@stonethree.com> + +* sem_timedwait() now uses tighter checks for unreasonable +abstime values - that would result in unexpected timeout values. + +* ptw32_cond_wait_cleanup() no longer mysteriously consumes +CV signals but may produce more spurious wakeups. 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. + + +SNAPSHOT 2001-07-12 +------------------- + +To be added + + +SNAPSHOT 2001-07-03 +------------------- + +To be added + + +SNAPSHOT 2000-08-13 +------------------- + +New: +- Renamed DLL and LIB files: + pthreadVSE.dll (MS VC++/Structured EH) + pthreadVSE.lib + pthreadVCE.dll (MS VC++/C++ EH) + pthreadVCE.lib + pthreadGCE.dll (GNU G++/C++ EH) + libpthreadw32.a + + Both your application and the pthread dll should use the + same exception handling scheme. + +Bugs fixed: +- MSVC++ C++ exception handling. + +Some new tests have been added. + + +SNAPSHOT 2000-08-10 +------------------- + +New: +- asynchronous cancelation on X86 (Jason Nye) +- Makefile compatible with MS nmake to replace + buildlib.bat +- GNUmakefile for Mingw32 +- tests/Makefile for MS nmake replaces runall.bat +- tests/GNUmakefile for Mingw32 + +Bugs fixed: +- kernel32 load/free problem +- attempt to hide internel exceptions from application + exception handlers (__try/__except and try/catch blocks) +- Win32 thread handle leakage bug + (David Baggett/Paul Redondo/Eyal Lebedinsky) + +Some new tests have been added. + + +SNAPSHOT 1999-11-02 +------------------- + +Bugs fixed: +- ctime_r macro had an incorrect argument (Erik Hensema), +- threads were not being created + PTHREAD_CANCEL_DEFERRED. This should have + had little effect as deferred is the only + supported type. (Ross Johnson). + +Some compatibility improvements added, eg. +- pthread_setcancelstate accepts NULL pointer + for the previous value argument. Ditto for + pthread_setcanceltype. This is compatible + with Solaris but should not affect + standard applications (Erik Hensema) + +Some new tests have been added. + + +SNAPSHOT 1999-10-17 +------------------- + +Bug fix - Cancelation of threads waiting on condition variables +now works properly (Lorin Hochstein and Peter Slacik) + + +SNAPSHOT 1999-08-12 +------------------- + +Fixed exception stack cleanup if calling pthread_exit() +- (Lorin Hochstein and John Bossom). + +Fixed bugs in condition variables - (Peter Slacik): + - additional contention checks + - properly adjust number of waiting threads after timed + condvar timeout. + + +SNAPSHOT 1999-05-30 +------------------- + +Some minor bugs have been fixed.

-==============
-
-Pthreads-win32 is free software, distributed under the GNU Lesser
-General Public License (LGPL). See the file 'COPYING.LIB' for terms
-and conditions. Also see the file 'COPYING' for information
-specific to pthreads-win32, copyrights and the LGPL.
-
-
-What is it?
------------
-
-Pthreads-win32 is an Open Source Software implementation of the
-Threads component of the POSIX 1003.1c 1995 Standard (or later)
-for Microsoft's Win32 environment. Some functions from POSIX
-1003.1b are also supported including semaphores. Other related
-functions include the set of read-write lock functions. The
-library also supports some of the functionality of the Open
-Group's Single Unix specification, version 2, namely mutex types,
-plus some common and pthreads-win32 specific non-portable
-routines (see README.NONPORTABLE).
-
-See the file "ANNOUNCE" for more information including standards
-conformance details and the list of supported and unsupported
-routines.
-
-
-Prerequisites
--------------
-MSVC or GNU C (MinGW32 MSys development kit)
- To build from source.
-
-QueueUserAPCEx by Panagiotis E. Hadjidoukas
- For true async cancelation of threads (including blocked threads).
- This is a DLL and Windows driver that provides pre-emptive APC
- by forcing threads into an alertable state when the APC is queued.
- Both the DLL and driver are provided with the pthreads-win32.exe
- self-unpacking ZIP, and on the pthreads-win32 FTP site (in source
- and pre-built forms). Currently this is a separate LGPL package to
- pthreads-win32. See the README in the QueueUserAPCEx folder for
- installation instructions.
-
- Pthreads-win32 will automatically detect if the QueueUserAPCEx DLL
- QuserEx.DLL is available and whether the driver AlertDrv.sys is
- loaded. If it is not available, pthreads-win32 will simulate async
- cancelation, which means that it can async cancel only threads that
- are runnable. The simulated async cancellation cannot cancel blocked
- threads.
-
-
-Library naming
---------------
-
-Because the library is being built using various exception
-handling schemes and compilers - and because the library
-may not work reliably if these are mixed in an application,
-each different version of the library has it's own name.
-
-Note 1: the incompatibility is really between EH implementations
-of the different compilers. It should be possible to use the
-standard C version from either compiler with C++ applications
-built with a different compiler. If you use an EH version of
-the library, then you must use the same compiler for the
-application. This is another complication and dependency that
-can be avoided by using only the standard C library version.
-
-Note 2: if you use a standard C pthread*.dll with a C++
-application, then any functions that you define that are
-intended to be called via pthread_cleanup_push() must be
-__cdecl.
-
-Note 3: the intention was to also name either the VC or GC
-version (it should be arbitrary) as pthread.dll, including
-pthread.lib and libpthread.a as appropriate. This is no longer
-likely to happen.
-
-Note 4: the compatibility number was added so that applications
-can differentiate between binary incompatible versions of the
-libs and dlls.
-
-In general:
- pthread[VG]{SE,CE,C}c.dll
- pthread[VG]{SE,CE,C}c.lib
-
-where:
- [VG] indicates the compiler
- V - MS VC, or
- G - GNU C
-
- {SE,CE,C} indicates the exception handling scheme
- SE - Structured EH, or
- CE - C++ EH, or
- C - no exceptions - uses setjmp/longjmp
-
- c - DLL compatibility number indicating ABI and API
- compatibility with applications built against
- any snapshot with the same compatibility number.
- See 'Version numbering' below.
-
-The name may also be suffixed by a 'd' to indicate a debugging version
-of the library. E.g. pthreadVC2d.lib. Debugging versions contain
-additional information for debugging (symbols etc) and are often not
-optimised in any way (compiled with optimisation turned off).
-
-For example:
- pthreadVSE.dll (MSVC/SEH)
- pthreadGCE.dll (GNUC/C++ EH)
- pthreadGC.dll (GNUC/not dependent on exceptions)
- pthreadVC1.dll (MSVC/not dependent on exceptions - not binary
- compatible with pthreadVC.dll)
- pthreadVC2.dll (MSVC/not dependent on exceptions - not binary
- compatible with pthreadVC1.dll or pthreadVC.dll)
-
-The GNU library archive file names have correspondingly changed to:
-
- libpthreadGCEc.a
- libpthreadGCc.a
-
-
-Versioning numbering
---------------------
-
-Version numbering is separate from the snapshot dating system, and
-is the canonical version identification system embedded within the
-DLL using the Microsoft version resource system. The versioning
-system chosen follows the GNU Libtool system. See
-http://www.gnu.org/software/libtool/manual.html section 6.2.
-
-See the resource file 'version.rc'.
-
-Microsoft version numbers use 4 integers:
-
- 0.0.0.0
-
-Pthreads-win32 uses the first 3 following the Libtool convention.
-The fourth is commonly used for the build number, but will be reserved
-for future use.
-
- current.revision.age.0
-
-The numbers are changed as follows:
-
-1. If the library source code has changed at all since the last update,
- then increment revision (`c:r:a' becomes `c:r+1:a').
-2. If any interfaces have been added, removed, or changed since the last
- update, increment current, and set revision to 0.
-3. If any interfaces have been added since the last public release, then
- increment age.
-4. If any interfaces have been removed or changed since the last public
- release, then set age to 0.
-
-
-DLL compatibility numbering is an attempt to ensure that applications
-always load a compatible pthreads-win32 DLL by using a DLL naming system
-that is consistent with the version numbering system. It also allows
-older and newer DLLs to coexist in the same filesystem so that older
-applications can continue to be used. For pre .NET Windows systems,
-this inevitably requires incompatible versions of the same DLLs to have
-different names.
-
-Pthreads-win32 has adopted the Cygwin convention of appending a single
-integer number to the DLL name. The number used is based on the library
-version number and is computed as 'current' - 'age'.
-
-(See http://home.att.net/~perlspinr/libversioning.html for a nicely
-detailed explanation.)
-
-Using this method, DLL name/s will only change when the DLL's
-backwards compatibility changes. Note that the addition of new
-'interfaces' will not of itself change the DLL's compatibility for older
-applications.
-
-
-Which of the several dll versions to use?
------------------------------------------
-or,
----
-What are all these pthread*.dll and pthread*.lib files?
--------------------------------------------------------
-
-Simple, use either pthreadGCv.* if you use GCC, or pthreadVCv.* if you
-use MSVC - where 'v' is the DLL versioning (compatibility) number.
-
-Otherwise, you need to choose carefully and know WHY.
-
-The most important choice you need to make is whether to use a
-version that uses exceptions internally, or not. There are versions
-of the library that use exceptions as part of the thread
-cancelation and exit implementation. The default version uses
-setjmp/longjmp.
-
-There is some contension amongst POSIX threads experts as
-to how POSIX threads cancelation and exit should work
-with languages that use exceptions, e.g. C++ and even C
-(Microsoft's Structured Exceptions).
-
-The issue is: should cancelation of a thread in, say,
-a C++ application cause object destructors and C++ exception
-handlers to be invoked as the stack unwinds during thread
-exit, or not?
-
-There seems to be more opinion in favour of using the
-standard C version of the library (no EH) with C++ applications
-for the reason that this appears to be the assumption commercial
-pthreads implementations make. Therefore, if you use an EH version
-of pthreads-win32 then you may be under the illusion that
-your application will be portable, when in fact it is likely to
-behave differently when linked with other pthreads libraries.
-
-Now you may be asking: then why have you kept the EH versions of
-the library?
-
-There are a couple of reasons:
-- there is division amongst the experts and so the code may
- be needed in the future. Yes, it's in the repository and we
- can get it out anytime in the future, but it would be difficult
- to find.
-- pthreads-win32 is one of the few implementations, and possibly
- the only freely available one, that has EH versions. It may be
- useful to people who want to play with or study application
- behaviour under these conditions.
-
-Notes:
-
-[If you use either pthreadVCE or pthreadGCE]
-
-1. [See also the discussion in the FAQ file - Q2, Q4, and Q5]
-
-If your application contains catch(...) blocks in your POSIX
-threads then you will need to replace the "catch(...)" with the macro
-"PtW32Catch", eg.
-
- #ifdef PtW32Catch
- PtW32Catch {
- ...
- }
- #else
- catch(...) {
- ...
- }
- #endif
-
-Otherwise neither pthreads cancelation nor pthread_exit() will work
-reliably when using versions of the library that use C++ exceptions
-for cancelation and thread exit.
-
-This is due to what is believed to be a C++ compliance error in VC++
-whereby you may not have multiple handlers for the same exception in
-the same try/catch block. GNU G++ doesn't have this restriction.
-
-
-Other name changes
-------------------
-
-All snapshots prior to and including snapshot 2000-08-13
-used "_pthread_" as the prefix to library internal
-functions, and "_PTHREAD_" to many library internal
-macros. These have now been changed to "ptw32_" and "PTW32_"
-respectively so as to not conflict with the ANSI standard's
-reservation of identifiers beginning with "_" and "__" for
-use by compiler implementations only.
-
-If you have written any applications and you are linking
-statically with the pthreads-win32 library then you may have
-included a call to _pthread_processInitialize. You will
-now have to change that to ptw32_processInitialize.
-
-
-Cleanup code default style
---------------------------
-
-Previously, if not defined, the cleanup style was determined automatically
-from the compiler used, and one of the following was defined accordingly:
-
- __CLEANUP_SEH MSVC only
- __CLEANUP_CXX C++, including MSVC++, GNU G++
- __CLEANUP_C C, including GNU GCC, not MSVC
-
-These defines determine the style of cleanup (see pthread.h) and,
-most importantly, the way that cancelation and thread exit (via
-pthread_exit) is performed (see the routine ptw32_throw()).
-
-In short, the exceptions versions of the library throw an exception
-when a thread is canceled, or exits via pthread_exit(). This exception 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 snapshot, 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/all
-commercial Unix POSIX threads implementations.
-
-Although it was not clearly documented before, it is still necessary to
-build your application using the same __CLEANUP_* define as was
-used for the version of the library that you link with, so that the
-correct parts of pthread.h are included. That is, the possible
-defines require the following library versions:
-
- __CLEANUP_SEH pthreadVSE.dll
- __CLEANUP_CXX pthreadVCE.dll or pthreadGCE.dll
- __CLEANUP_C pthreadVC.dll or pthreadGC.dll
-
-It is recommended that you let pthread.h use it's default __CLEANUP_C
-for both library and application builds. That is, don't define any of
-the above, and then link with pthreadVC.lib (MSVC or MSVC++) and
-libpthreadGC.a (MinGW GCC or G++). The reason is explained below, but
-another reason is that the prebuilt pthreadVCE.dll is currently broken.
-Versions built with MSVC++ later than version 6 may not be broken, but I
-can't verify this yet.
-
-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 pthreads platform
-you use. Or at least this is the hope.

-Building under Mingw32
-----------------------
-
-The dll can be built easily with recent versions of Mingw32.
-(The distributed versions are built using Mingw32 and MsysDTK
-from www.mingw32.org.)
-
-From the source directory, run make for help information. E.g.:
-
-$ make
-Run one of the following command lines:
-make clean GC (to build the GNU C dll with C cleanup code)
-make clean GCE (to build the GNU C dll with C++ exception handling)

-
-
-Building the library as a statically linkable library
------------------------------------------------------
-
-General: PTW32_STATIC_LIB must be defined for both the library build and the
-application build. The following 'make' command lines will define this for the
-static library builds.
-
-MSVC (creates pthreadVCnd.lib as a static link lib):
-
-nmake clean VC-static
-
-
-MinGW32 (creates libpthreadGCn.a as a static link lib):
-
-make clean GC-static
-
-
-Define PTW32_STATIC_LIB when building your application.
-
-The tests makefiles have the same targets but only check that the
-static library is statically linkable. They don't run the full
-testsuite. To run the full testsuite, build the dlls and run the
-dll test targets.
-
-
-Building the library under Cygwin
----------------------------------
-
-Cygwin is implementing it's own POSIX threads routines and these
-will be the ones to use if you develop using Cygwin.
-
-
-Ready to run binaries
----------------------
-
-For convenience, the following ready-to-run files can be downloaded
-from the FTP site (see under "Availability" below):
-
- pthread.h
- semaphore.h
- sched.h

+PTHREADS-WIN32 +============== + +Pthreads-win32 is free software, distributed under the GNU Lesser +General Public License (LGPL). See the file 'COPYING.LIB' for terms +and conditions. Also see the file 'COPYING' for information +specific to pthreads-win32, copyrights and the LGPL. + + +What is it? +----------- + +Pthreads-win32 is an Open Source Software implementation of the +Threads component of the POSIX 1003.1c 1995 Standard (or later) +for Microsoft's Win32 environment. Some functions from POSIX +1003.1b are also supported including semaphores. Other related +functions include the set of read-write lock functions. The +library also supports some of the functionality of the Open +Group's Single Unix specification, version 2, namely mutex types, +plus some common and pthreads-win32 specific non-portable +routines (see README.NONPORTABLE). + +See the file "ANNOUNCE" for more information including standards +conformance details and the list of supported and unsupported +routines. + + +Prerequisites +------------- +MSVC or GNU C (MinGW32 MSys development kit) + To build from source. + +QueueUserAPCEx by Panagiotis E. Hadjidoukas + For true async cancelation of threads (including blocked threads). + This is a DLL and Windows driver that provides pre-emptive APC + by forcing threads into an alertable state when the APC is queued. + Both the DLL and driver are provided with the pthreads-win32.exe + self-unpacking ZIP, and on the pthreads-win32 FTP site (in source + and pre-built forms). Currently this is a separate LGPL package to + pthreads-win32. See the README in the QueueUserAPCEx folder for + installation instructions. + + Pthreads-win32 will automatically detect if the QueueUserAPCEx DLL + QuserEx.DLL is available and whether the driver AlertDrv.sys is + loaded. If it is not available, pthreads-win32 will simulate async + cancelation, which means that it can async cancel only threads that + are runnable. The simulated async cancellation cannot cancel blocked + threads. + + +Library naming +-------------- + +Because the library is being built using various exception +handling schemes and compilers - and because the library +may not work reliably if these are mixed in an application, +each different version of the library has it's own name. + +Note 1: the incompatibility is really between EH implementations +of the different compilers. It should be possible to use the +standard C version from either compiler with C++ applications +built with a different compiler. If you use an EH version of +the library, then you must use the same compiler for the +application. This is another complication and dependency that +can be avoided by using only the standard C library version. + +Note 2: if you use a standard C pthread*.dll with a C++ +application, then any functions that you define that are +intended to be called via pthread_cleanup_push() must be +__cdecl. + +Note 3: the intention was to also name either the VC or GC +version (it should be arbitrary) as pthread.dll, including +pthread.lib and libpthread.a as appropriate. This is no longer +likely to happen. + +Note 4: the compatibility number was added so that applications +can differentiate between binary incompatible versions of the +libs and dlls. + +In general: + pthread[VG]{SE,CE,C}c.dll + pthread[VG]{SE,CE,C}c.lib + +where: + [VG] indicates the compiler + V - MS VC, or + G - GNU C + + {SE,CE,C} indicates the exception handling scheme + SE - Structured EH, or + CE - C++ EH, or + C - no exceptions - uses setjmp/longjmp + + c - DLL compatibility number indicating ABI and API + compatibility with applications built against + any snapshot with the same compatibility number. + See 'Version numbering' below. + +The name may also be suffixed by a 'd' to indicate a debugging version +of the library. E.g. pthreadVC2d.lib. Debugging versions contain +additional information for debugging (symbols etc) and are often not +optimised in any way (compiled with optimisation turned off). + +For example: + pthreadVSE.dll (MSVC/SEH) + pthreadGCE.dll (GNUC/C++ EH) + pthreadGC.dll (GNUC/not dependent on exceptions) + pthreadVC1.dll (MSVC/not dependent on exceptions - not binary + compatible with pthreadVC.dll) + pthreadVC2.dll (MSVC/not dependent on exceptions - not binary + compatible with pthreadVC1.dll or pthreadVC.dll) + +The GNU library archive file names have correspondingly changed to: + + libpthreadGCEc.a + libpthreadGCc.a + + +Versioning numbering +-------------------- + +Version numbering is separate from the snapshot dating system, and +is the canonical version identification system embedded within the +DLL using the Microsoft version resource system. The versioning +system chosen follows the GNU Libtool system. See +http://www.gnu.org/software/libtool/manual.html section 6.2. + +See the resource file 'version.rc'. + +Microsoft version numbers use 4 integers: + + 0.0.0.0 + +Pthreads-win32 uses the first 3 following the Libtool convention. +The fourth is commonly used for the build number, but will be reserved +for future use. + + current.revision.age.0 + +The numbers are changed as follows: + +1. If the library source code has changed at all since the last update, + then increment revision (`c:r:a' becomes `c:r+1:a'). +2. If any interfaces have been added, removed, or changed since the last + update, increment current, and set revision to 0. +3. If any interfaces have been added since the last public release, then + increment age. +4. If any interfaces have been removed or changed since the last public + release, then set age to 0. + + +DLL compatibility numbering is an attempt to ensure that applications +always load a compatible pthreads-win32 DLL by using a DLL naming system +that is consistent with the version numbering system. It also allows +older and newer DLLs to coexist in the same filesystem so that older +applications can continue to be used. For pre .NET Windows systems, +this inevitably requires incompatible versions of the same DLLs to have +different names. + +Pthreads-win32 has adopted the Cygwin convention of appending a single +integer number to the DLL name. The number used is based on the library +version number and is computed as 'current' - 'age'. + +(See http://home.att.net/~perlspinr/libversioning.html for a nicely +detailed explanation.) + +Using this method, DLL name/s will only change when the DLL's +backwards compatibility changes. Note that the addition of new +'interfaces' will not of itself change the DLL's compatibility for older +applications. + + +Which of the several dll versions to use? +----------------------------------------- +or, +--- +What are all these pthread*.dll and pthread*.lib files? +------------------------------------------------------- + +Simple, use either pthreadGCv.* if you use GCC, or pthreadVCv.* if you +use MSVC - where 'v' is the DLL versioning (compatibility) number. + +Otherwise, you need to choose carefully and know WHY. + +The most important choice you need to make is whether to use a +version that uses exceptions internally, or not. There are versions +of the library that use exceptions as part of the thread +cancelation and exit implementation. The default version uses +setjmp/longjmp. + +There is some contension amongst POSIX threads experts as +to how POSIX threads cancelation and exit should work +with languages that use exceptions, e.g. C++ and even C +(Microsoft's Structured Exceptions). + +The issue is: should cancelation of a thread in, say, +a C++ application cause object destructors and C++ exception +handlers to be invoked as the stack unwinds during thread +exit, or not? + +There seems to be more opinion in favour of using the +standard C version of the library (no EH) with C++ applications +for the reason that this appears to be the assumption commercial +pthreads implementations make. Therefore, if you use an EH version +of pthreads-win32 then you may be under the illusion that +your application will be portable, when in fact it is likely to +behave differently when linked with other pthreads libraries. + +Now you may be asking: then why have you kept the EH versions of +the library? + +There are a couple of reasons: +- there is division amongst the experts and so the code may + be needed in the future. Yes, it's in the repository and we + can get it out anytime in the future, but it would be difficult + to find. +- pthreads-win32 is one of the few implementations, and possibly + the only freely available one, that has EH versions. It may be + useful to people who want to play with or study application + behaviour under these conditions. + +Notes: + +[If you use either pthreadVCE or pthreadGCE] + +1. [See also the discussion in the FAQ file - Q2, Q4, and Q5] + +If your application contains catch(...) blocks in your POSIX +threads then you will need to replace the "catch(...)" with the macro +"PtW32Catch", eg. + + #ifdef PtW32Catch + PtW32Catch { + ... + } + #else + catch(...) { + ... + } + #endif + +Otherwise neither pthreads cancelation nor pthread_exit() will work +reliably when using versions of the library that use C++ exceptions +for cancelation and thread exit. + +This is due to what is believed to be a C++ compliance error in VC++ +whereby you may not have multiple handlers for the same exception in +the same try/catch block. GNU G++ doesn't have this restriction. + + +Other name changes +------------------ + +All snapshots prior to and including snapshot 2000-08-13 +used "_pthread_" as the prefix to library internal +functions, and "_PTHREAD_" to many library internal +macros. These have now been changed to "ptw32_" and "PTW32_" +respectively so as to not conflict with the ANSI standard's +reservation of identifiers beginning with "_" and "__" for +use by compiler implementations only. + +If you have written any applications and you are linking +statically with the pthreads-win32 library then you may have +included a call to _pthread_processInitialize. You will +now have to change that to ptw32_processInitialize. + + +Cleanup code default style +-------------------------- + +Previously, if not defined, the cleanup style was determined automatically +from the compiler used, and one of the following was defined accordingly: + + __CLEANUP_SEH MSVC only + __CLEANUP_CXX C++, including MSVC++, GNU G++ + __CLEANUP_C C, including GNU GCC, not MSVC + +These defines determine the style of cleanup (see pthread.h) and, +most importantly, the way that cancelation and thread exit (via +pthread_exit) is performed (see the routine ptw32_throw()). + +In short, the exceptions versions of the library throw an exception +when a thread is canceled, or exits via pthread_exit(). This exception 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 snapshot, 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/all +commercial Unix POSIX threads implementations. + +Although it was not clearly documented before, it is still necessary to +build your application using the same __CLEANUP_* define as was +used for the version of the library that you link with, so that the +correct parts of pthread.h are included. That is, the possible +defines require the following library versions: + + __CLEANUP_SEH pthreadVSE.dll + __CLEANUP_CXX pthreadVCE.dll or pthreadGCE.dll + __CLEANUP_C pthreadVC.dll or pthreadGC.dll + +It is recommended that you let pthread.h use it's default __CLEANUP_C +for both library and application builds. That is, don't define any of +the above, and then link with pthreadVC.lib (MSVC or MSVC++) and +libpthreadGC.a (MinGW GCC or G++). The reason is explained below, but +another reason is that the prebuilt pthreadVCE.dll is currently broken. +Versions built with MSVC++ later than version 6 may not be broken, but I +can't verify this yet. + +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 pthreads platform +you use. Or at least this is the hope. + + +Building under VC++ using C++ EH, Structured EH, or just C +---------------------------------------------------------- + +From the source directory run nmake without any arguments to list +help information. E.g. + +$ nmake + +Microsoft (R) Program Maintenance Utility Version 6.00.8168.0 +Copyright (C) Microsoft Corp 1988-1998.

- *
- * thread
- * reference to the thread that owns the association.
- * As long as this is not NULL, the association remains

- *
- * key
- * reference to the key that owns the association.
- * As long as this is not NULL, the association remains
- * referenced by the pthread_key_t.
- *
- * 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.
- *
- * nextThread
- * The pthread_key_t->threads attribute is the head of
- * a chain of assoctiations that runs through the
- * nextThreads link. This chain provides the 1 to many
- * relationship between a pthread_key_t and all the
- * PThreads that have called pthread_setspecific for
- * this pthread_key_t.
- *
- *
- * Notes:
- * 1) As long as one of the attributes, thread or key, is
- * not NULL, the association is being referenced; once
- * both are NULL, the association must be released.
- *
- * 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.

- * ------------------------------------------------------
- * DOCPUBLIC
- * If any thread in a process with a once_control parameter
- * makes a call to pthread_once(), the first call will summon
- * the init_routine(), but subsequent calls will not. The
- * once_control parameter determines whether the associated
- * initialization routine has been called. The init_routine()
- * is complete upon return of pthread_once().
- * This function guarantees that one and only one thread
- * executes the initialization routine, init_routine when
- * access is controlled by the pthread_once_t control
- * key.
- *
- * pthread_once() is not a cancelation point, but the init_routine
- * can be. If it's cancelled then the effect on the once_control is
- * as if pthread_once had never been entered.
- *
- * PARAMETERS
- * once_control
- * pointer to an instance of pthread_once_t
- *
- * init_routine
- * pointer to an initialization routine

- * 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.

- * GNUmakefile: modified to work in the MsysDTK (newer MinGW)

- using gcc -x c++ doesn't link with required c++ libs by default,

- * exception3.c: Correct recent change.

-
- * 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).
