+ PTHREADS-WIN32 RELEASE 2.8.0 (2006-12-22)
+ -----------------------------------------
+ Web Site: http://sources.redhat.com/pthreads-win32/
+ FTP Site: ftp://sources.redhat.com/pub/pthreads-win32
+ Maintainer: Ross Johnson <rpj@callisto.canberra.edu.au>
+
+
+We are pleased to announce the availability of a new release of
+Pthreads-win32, an Open Source Software implementation of the
+Threads component of the POSIX 1003.1 2001 Standard for Microsoft's
+Win32 environment. Some functions from other sections of POSIX
+1003.1 2001 are also supported including semaphores and scheduling
+functions.
+
+Some common non-portable functions are also implemented for
+additional compatibility, as are a few functions specific
+to pthreads-win32 for easier integration with Win32 applications.
+
+Pthreads-win32 is free software, distributed under the GNU Lesser
+General Public License (LGPL).
+
+
+Acknowledgements
+----------------
+This library is based originally on a Win32 pthreads
+implementation contributed by John Bossom <John.Bossom@cognos.com>.
+
+The implementation of Condition Variables uses algorithms developed
+by Alexander Terekhov and Louis Thomas.
+
+The implementation of POSIX mutexes has been improved by Thomas Pfaff
+and later by Alexander Terekhov.
+
+The implementation of Spinlocks and Barriers was contributed
+by Ross Johnson.
+
+The implementation of read/write locks was contributed by
+Aurelio Medina and improved by Alexander Terekhov.
+
+Many others have contributed significant time and effort to solve crutial
+problems in order to make the library workable, robust and reliable.
+
+Thanks to Xavier Leroy for granting permission to use and modify his
+LinuxThreads manual pages.
+
+Thanks to The Open Group for making the Single Unix Specification
+publicly available - many of the manual pages included in the package
+were extracted from it.
+
+There is also a separate CONTRIBUTORS file. This file and others are

+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:

+----------
+Known bugs
+----------
+
+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.
+
+2. Cancellation problems in optimised code
+ - Milan Gardian
+
+ This is suspected to be a compiler bug in VC6.0, and also seen in
+ VC7.0 and VS .NET 2003. The GNU C++ compiler does not have a problem
+ with this, and it has been reported that the Intel C++ 8.1 compiler
+ and Visual C++ 2005 Express Edition Beta2 pass tests\semaphore4.c
+ (which exposes the bug).
+
+ Workaround [rpj - 2 Feb 2002]
+ -----------------------------
+ [Please note: this workaround did not solve a similar problem in
+ snapshot-2004-11-03 or later, even though similar symptoms were seen.
+ tests\semaphore4.c fails in that snapshot for the VCE version of the
+ DLL.]
+
+ 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.
+
+ [/rpj]
+
+ 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.
+
+3. The Borland Builder 5.5 version of the library produces memory read exceptions
+in some tests.
+
+4. pthread_barrier_wait() can deadlock if the number of potential calling
+threads for a particular barrier is greater than the barrier count parameter
+given to pthread_barrier_init() for that barrier.
+
+This is due to the very lightweight implementation of pthread-win32 barriers.
+To cope with more than "count" possible waiters, barriers must effectively
+implement all the same safeguards as condition variables, making them much
+"heavier" than at present.
+
+The workaround is to ensure that no more than "count" threads attempt to wait
+at the barrier.
+
+5. Canceling a thread blocked on pthread_once appears not to work in the MSVC++
+version of the library "pthreadVCE.dll". The test case "once3.c" hangs. I have no
+clues on this at present. All other versions pass this test ok - pthreadsVC.dll,
+pthreadsVSE.dll, pthreadsGC.dll and pthreadsGCE.dll.

+
+Why pthreads-win32 did not use the GNU General Public License
+-------------------------------------------------------------
+
+ The goal of the pthreads-win32 project has been to
+ provide a quality and complete implementation of the POSIX
+ threads API for Microsoft Windows within the limits imposed
+ by virtue of it being a stand-alone library and not
+ linked directly to other POSIX compliant libraries. For
+ example, some functions and features, such as those based
+ on POSIX signals, are missing.
+
+ Pthreads-win32 is a library, available in several different
+ versions depending on supported compilers, and may be used
+ as a dynamically linked module or a statically linked set of
+ binary modules. It is not an application on it's own.
+
+ It was fully intended that pthreads-win32 be usable with
+ commercial software not covered by either the GPL or the LGPL
+ licenses. Pthreads-win32 has many contributors to it's
+ code base, many of whom have done so because they have
+ used the library in commercial or proprietry software
+ projects.
+
+ Releasing pthreads-win32 under the LGPL ensures that the
+ library can be used widely, while at the same time ensures
+ that bug fixes and improvements to the pthreads-win32 code
+ itself is returned to benefit all current and future users
+ of the library.
+
+ Although pthreads-win32 makes it possible for applications
+ that use POSIX threads to be ported to Win32 platforms, the
+ broader goal of the project is to encourage the use of open
+ standards, and in particular, to make it just a little easier
+ for developers writing Win32 applications to consider
+ widening the potential market for their products.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Lesser General Public
+ License as published by the Free Software Foundation; either
+ version 2.1 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Lesser General Public License for more details.

+ License along with this library; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+2006-12-20 Ross Johnson <ross.johnson@homemail.com.au>
+
+ * sem_destroy.c: Fix the race involving invalidation of the sema;
+ fix incorrect return of EBUSY resulting from the mutex trylock
+ on the private mutex guard.
+ * sem_wait.c: Add check for invalid sem_t after acquiring the
+ sem_t state guard mutex and before affecting changes to sema state.
+ * sem_trywait.c: Likewise.
+ * sem_timedwait.c: Likewise.
+ * sem_getvalue.c: Likewise.
+ * sem_post.c: Similar.
+ * sem_post_multiple.c: Likewise.
+ * sem_init.c: Set max Win32 semaphore count to SEM_VALUE_MAX (was
+ _POSIX_SEM_VALUE_MAX, which is a lower value - the minimum).
+
+ * pthread_win32_attach_detach_np.c (pthread_win32_process_attach_np):
+ Load COREDLL.DLL under WINCE to check existence of
+ InterlockedCompareExchange() routine. This used to be done to test
+ for TryEnterCriticalSection() but was removed when this was no
+ longer needed.
+
+2006-01-25 Prashant Thakre <prashant.thakre at gmail.com>
+
+ * pthread_cancel.c: Added _M_IA64 register context support.
+
+2005-05-13 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * pthread_kill.c (pthread_kill): Remove check for Win32 thread
+ priority (to confirm HANDLE validity). Useless since thread HANDLEs
+ a not recycle-unique.
+
+2005-05-30 Vladimir Kliatchko <vladimir at kliatchko.com>
+
+ * pthread_once.c: Re-implement using an MCS queue-based lock. The form
+ of pthread_once is as proposed by Alexander Terekhov (see entry of
+ 2005-03-13). The MCS lock implementation does not require a unique
+ 'name' to identify the lock between threads. Attempts to get the Event
+ or Semaphore based versions of pthread_once to a satisfactory level
+ of robustness have thus far failed. The last problem (avoiding races
+ involving non recycle-unique Win32 HANDLEs) was giving everyone
+ grey hair trying to solve it.
+
+ * ptw32_MCS_lock.c: New MCS queue-based lock implementation. These
+ locks are efficient: they have very low overhead in the uncontended case;
+ are efficient in contention and minimise cache-coherence updates in
+ managing the user level FIFO queue; do not require an ABI change in the
+ library.
+
+2005-05-27 Alexander Gottwald <alexander.gottwald at s1999.tu-chemnitz.de>
+
+ * pthread.h: Some things, like HANDLE, were only defined if
+ PTW32_LEVEL was >= 3. They should always be defined.
+
+2005-05-25 Vladimir Kliatchko <vladimir at kliatchko.com>
+
+ * pthread_once.c: Eliminate all priority operations and other
+ complexity by replacing the event with a semaphore. The advantage
+ of the change is the ability to release just one waiter if the
+ init_routine thread is cancelled yet still release all waiters when
+ done. Simplify once_control state checks to improve efficiency
+ further.
+
+2005-05-24 Mikael Magnusson <mikaelmagnusson at glocalnet.net>
+
+ * GNUmakefile: Patched to allow cross-compile with mingw32 on Linux.
+ It uses macros instead of referencing dlltool, gcc and g++ directly;
+ added a call to ranlib. For example the GC static library can be
+ built with:
+ make CC=i586-mingw32msvc-gcc RC=i586-mingw32msvc-windres \
+ RANLIB=i586-mingw32msvc-ranlib clean GC-static
+
+2005-05-13 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * pthread_win32_attach_detach_np.c (pthread_win32_thread_detach_np):
+ Move on-exit-only stuff from ptw32_threadDestroy() to here.
+ * ptw32_threadDestroy.c: It's purpose is now only to reclaim thread
+ resources for detached threads, or via pthread_join() or
+ pthread_detach() on joinable threads.
+ * ptw32_threadStart.c: Calling user destruct routines has moved to
+ pthread_win32_thread_detach_np(); call pthread_win32_thread_detach_np()
+ directly if statically linking, otherwise do so via dllMain; store
+ thread return value in thread struct for all cases, including
+ cancellation and exception exits; thread abnormal exits go via
+ pthread_win32_thread_detach_np.
+ * pthread_join.c (pthread_join): Don't try to get return code from
+ Win32 thread - always get it from he thread struct.
+ * pthread_detach.c (pthread_detach): reduce extent of the thread
+ existence check since we now don't care if the Win32 thread HANDLE has
+ been closed; reclaim thread resources if the thread has exited already.
+ * ptw32_throw.c (ptw32_throw): For Win32 threads that are not implicit,
+ only Call thread cleanup if statically linking, otherwise leave it to
+ dllMain.
+ * sem_post.c (_POSIX_SEM_VALUE_MAX): Change to SEM_VALUE_MAX.
+ * sem_post_multiple.c: Likewise.
+ * sem_init.c: Likewise.
+
+2005-05-10 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * pthread_join.c (pthread_join): Add missing check for thread ID
+ reference count in thread existence test; reduce extent of the
+ existence test since we don't care if the Win32 thread HANDLE has
+ been closed.
+
+2005-05-09 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * ptw32_callUserDestroyRoutines.c: Run destructor process (i.e.
+ loop over all keys calling destructors) up to

+ modify assoc management.
+ * pthread_key_delete.c: Modify assoc management.

+
+2005-05-02 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * implement.h (struct pthread_key_t_): Change threadsLock to keyLock
+ so as not to be confused with the per thread lock 'threadlock';
+ change all references to it.
+ * implement.h (struct ThreadKeyAssoc): Remove lock; add prevKey
+ and prevThread pointers; re-implemented all routines that use this
+ struct. The effect of this is to save one handle per association,
+ which could potentially equal the number of keys multiplied by the
+ number of threads, accumulating over time - and to free the
+ association memory as soon as it is no longer referenced by either
+ the key or the thread. Previously, the handle and memory were
+ released only after BOTH key and thread no longer referenced the
+ association. That is, often no association resources were released
+ until the process itself exited. In addition, at least one race
+ condition has been removed - where two threads could attempt to
+ release the association resources simultaneously - one via
+ ptw32_callUserDestroyRoutines and the other via
+ pthread_key_delete.
+ - thanks to Richard Hughes at Aculab for discovering the problem.
+ * pthread_key_create.c: See above.
+ * pthread_key_delete.c: See above.
+ * pthread_setspecific.c: See above.

+ * sem_timedwait.c: Modify comments.
+
+2005-04-25 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * ptw32_relmillisecs.c: New module; converts future abstime to
+ milliseconds relative to 'now'.
+ * pthread_mutex_timedlock.c: Use new ptw32_relmillisecs routine in
+ place of internal code; remove the NEED_SEM code - this routine is now
+ implemented for builds that define NEED_SEM (WinCE etc)
+ * sem_timedwait.c: Likewise; after timeout or cancellation,
+ re-attempt to acquire the semaphore in case one has been posted since
+ the timeout/cancel occurred. Thanks to Stefan Mueller.
+ * Makefile: Add ptw32_relmillisecs.c module; remove
+ ptw32_{in,de}crease_semaphore.c modules.
+ * GNUmakefile: Likewise.
+ * Bmakefile: Likewise.
+
+ * sem_init.c: Re-write the NEED_SEM code to be consistent with the
+ non-NEED_SEM code, but retaining use of an event in place of the w32 sema
+ for w32 systems that don't include semaphores (WinCE);
+ the NEED_SEM versions of semaphores has been broken for a long time but is
+ now fixed and supports all of the same routines as the non-NEED_SEM case.
+ * sem_destroy.c: Likewise.
+ * sem_wait.c: Likewise.
+ * sem_post.c: Likewise.
+ * sem_post_multple.c: Likewise.
+ * implement.h: Likewise.
+ * sem_timedwait.c: Likewise; this routine is now
+ implemented for builds that define NEED_SEM (WinCE etc).
+ * sem_trywait.c: Likewise.
+ * sem_getvalue.c: Likewise.
+
+ * pthread_once.c: Yet more changes, reverting closer to Gottlob Frege's
+ first design, but retaining cancellation, priority boosting, and adding
+ preservation of W32 error codes to make pthread_once transparent to
+ GetLastError.
+
+2005-04-11 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * pthread_once.c (pthread_once): Added priority boosting to
+ solve starvation problem after once_routine cancellation.
+ See notes in file.
+
+2005-04-06 Kevin Lussier <Kevin at codegreennetworks.com>
+
+ * Makefile: Added debug targets for all versions of the library.
+
+2005-04-01 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * GNUmakefile: Add target to build libpthreadGC1.a as a static link
+ library.
+ * Makefile: Likewise for pthreadGC1.lib.
+
+2005-04-01 Kevin Lussier <Kevin at codegreennetworks.com>
+
+ * sem_timedwait.c (sem_timedwait): Increase size of temp variables to
+ avoid int overflows for large timeout values.
+ * implement.h (int64_t): Include or define.
+
+2005-03-31 Dimitar Panayotov <develop at mail.bg>^M
+
+ * pthread.h: Fix conditional defines for static linking.
+ * sched.h: Liekwise.
+ * semaphore.h: Likewise.
+ * dll.c (PTW32_STATIC_LIB): Module is conditionally included
+ in the build.
+
+2005-03-16 Ross Johnson <ross at callisto.canberra.edu.au>^M
+
+ * pthread_setcancelstate.c: Undo the last change.
+
+2005-03-16 Ross Johnson <ross at callisto.canberra.edu.au>^M
+
+ * pthread_setcancelstate.c: Don't check for an async cancel event
+ if the library is using alertable async cancel..
+
+2005-03-14 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * pthread_once.c (pthread_once): Downgrade interlocked operations to simple
+ memory operations where these are protected by the critical section; edit
+ comments.
+
+2005-03-13 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_once.c (pthread_once): Completely redesigned; a change was
+ required to the ABI (pthread_once_t_), and resulting in a version
+ compatibility index increment.
+
+ NOTES:
+ The design (based on pseudo code contributed by Gottlob Frege) avoids
+ creating a kernel object if there is no contention. See URL for details:-
+ http://sources.redhat.com/ml/pthreads-win32/2005/msg00029.html
+ This uses late initialisation similar to the technique already used for
+ pthreads-win32 mutexes and semaphores (from Alexander Terekhov).
+
+ The subsequent cancelation cleanup additions (by rpj) could not be implemented
+ without sacrificing some of the efficiency in Gottlob's design. In particular,
+ although each once_control uses it's own event to block on, a global CS is
+ required to manage it - since the event must be either re-usable or
+ re-creatable under cancelation. This is not needed in the non-cancelable
+ design because it is able to mark the event as closed (forever).
+
+ When uncontested, a CS operation is equivalent to an Interlocked operation
+ in speed. So, in the final design with cancelability, an uncontested
+ once_control operation involves a minimum of five interlocked operations
+ (including the LeaveCS operation).
+
+ ALTERNATIVES:
+ An alternative design from Alexander Terekhov proposed using a named mutex,
+ as sketched below:-
+
+ if (!once_control) { // May be in TLS
+ named_mutex::guard guard(&once_control2);
+ if (!once_control2) {
+ <init>
+ once_control2 = true;
+ }
+ once_control = true;
+ }
+
+ A more detailed description of this can be found here:-
+ http://groups.yahoo.com/group/boost/message/15442
+
+ [Although the definition of a suitable PTHREAD_ONCE_INIT precludes use of the
+ TLS located flag, this is not critical.]
+
+ There are three primary concerns though:-
+ 1) The [named] mutex is 'created' even in the uncontended case.
+ 2) A system wide unique name must be generated.
+ 3) Win32 mutexes are VERY slow even in the uncontended case. An uncontested
+ Win32 mutex lock operation can be 50 (or more) times slower than an
+ uncontested EnterCS operation.
+
+ Ultimately, the named mutex trick is making use of the global locks maintained
+ by the kernel.
+
+ * pthread.h (pthread_once_t_): One flag and an event HANDLE added.
+ (PTHREAD_ONCE_INIT): Additional values included.
+
+2005-03-08 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_once.c (pthread_once): Redesigned to elliminate potential
+ starvation problem.
+ - reported by Gottlob Frege <gottlobfrege at gmail.com>
+
+ * ptw32_threadDestroy.c (ptw32_threadDestroy): Implicit threads were
+ not closing their Win32 thread duplicate handle.
+ - reported by Dmitrii Semii <bogolt at gmail.com>
+
+2005-01-25 Ralf Kubis <RKubis at mc.com>
+
+ * Attempted acquisition of recursive mutex was causing waiting
+ threads to not be woken when the mutex is released.
+
+ * GNUmakefile (GCE): Generate correct version resource comments.
+
+2005-01-01 Konstantin Voronkov <beowinkle at yahoo.com>
+
+ * pthread_mutex_lock.c (pthread_mutex_lock): The new atomic exchange
+ mutex algorithm is known to allow a thread to steal the lock off
+ FIFO waiting threads. The next waiting FIFO thread gets a spurious
+ wake-up and must attempt to re-acquire the lock. The woken thread
+ was setting itself as the mutex's owner before the re-acquisition.
+
+2004-11-22 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_cond_wait.c (ptw32_cond_wait_cleanup): Undo change
+ from 2004-11-02.
+ * Makefile (DLL_VER): Added for DLL naming suffix - see README.
+ * GNUmakefile (DLL_VER): Likewise.
+ * Wmakefile (DLL_VER): Likewise.
+ * Bmakefile (DLL_VER): Likewise.
+ * pthread.dsw (version.rc): Added to MSVS workspace.
+
+2004-11-20 Boudewijn Dekker <b.dekker at ellipsis.nl>
+
+ * pthread_getspecific.c (pthread_getspecific): Check for
+ invalid (NULL) key argument.
+
+2004-11-19 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * config.h (PTW32_THREAD_ID_REUSE_INCREMENT): Added to allow
+ building the library for either unique thread IDs like Solaris
+ or non-unique thread IDs like Linux; allows application developers
+ to override the library's default insensitivity to some apps
+ that may not be strictly POSIX compliant.
+ * version.rc: New resource module to encode version information
+ within the DLL.
+ * pthread.h: Added PTW32_VERSION* defines and grouped sections
+ required by resource compiler together; bulk of file is skipped
+ if RC_INVOKED. Defined some error numbers and other names for
+ Borland compiler.
+
+2004-11-02 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_cond_wait.c (ptw32_cond_wait_cleanup): Lock CV mutex at
+ start of cleanup handler rather than at the end.
+ * implement.h (PTW32_THREAD_REUSE_EMPTY): Renamed from *_BOTTOM.
+ (ptw32_threadReuseBottom): New global variable.
+ * global.c (ptw32_threadReuseBottom): Declare new variable.
+ * ptw32_reuse.c (ptw32_reuse): Change reuse LIFO stack to LILO queue
+ to more evenly distribute use of reusable thread IDs; use renamed
+ PTW32_THREAD_REUSE_EMPTY.
+ * ptw32_processTerminate.c (ptw2_processTerminate): Use renamed
+ PTW32_THREAD_REUSE_EMPTY.
+
+2004-10-31 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * implement.h (PThreadState): Add new state value
+ 'PThreadStateCancelPending'.
+ * pthread_testcancel.c (pthread_testcancel): Use new thread
+ 'PThreadStateCancelPending' state as short cut to avoid entering
+ kernel space via WaitForSingleObject() call. This was obviated
+ by user space sema acquisition in sem_wait() and sem_timedwait(),
+ which are also cancelation points. A call to pthread_testcancel()
+ was required, which introduced a kernel call, effectively nullifying
+ any gains made by the user space sem acquisition checks.
+ * pthread_cancel.c (pthread_cancel): Set new thread
+ 'PThreadStateCancelPending' state.
+
+2004-10-29 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * implement.h (pthread_t): Renamed to ptw32_thread_t; struct contains
+ all thread state.
+ * pthread.h (ptw32_handle_t): New general purpose struct to serve
+ as a handle for various reusable object IDs - currently only used
+ by pthread_t; contains a pointer to ptw32_thread_t (thread state)
+ and a general purpose uint for use as a reuse counter or flags etc.
+ (pthread_t): typedef'ed to ptw32_handle_t; the uint is the reuse
+ counter that allows the library to maintain unique POSIX thread IDs.
+ When the pthread struct reuse stack was introduced, threads would
+ often acquire an identical ID to a previously destroyed thread. The
+ same was true for the pre-reuse stack library, by virtue of pthread_t
+ being the address of the thread struct. The new pthread_t retains
+ the reuse stack but provides virtually unique thread IDs.
+ * sem_wait.c (ptw32_sem_wait_cleanup): New routine used for
+ cancelation cleanup.
+ * sem_timedwait.c (ptw32_sem_timedwait_cleanup): Likewise.
+
+2004-10-22 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * sem_init.c (sem_init): Introduce a 'lock' element in order to
+ replace the interlocked operations with conventional serialisation.
+ This is needed in order to be able to atomically modify the sema
+ value and perform Win32 sema release operations. Win32 semaphores are
+ used instead of events in order to support efficient multiple posting.
+ If the whole modify/release isn't atomic, a race between
+ sem_timedwait() and sem_post() could result in a release when there is
+ no waiting semaphore, which would cause too many threads to proceed.
+ * sem_wait.c (sem_wait): Use new 'lock'element.
+ * sem_timedwait.c (sem_timedwait): Likewise.
+ * sem_trywait.c (sem_trywait): Likewise.
+ * sem_post.c (sem_post): Likewise.
+ * sem_post_multiple.c (sem_post_multiple): Likewise.
+ * sem_getvalue.c (sem_getvalue): Likewise.
+ * ptw32_semwait.c (ptw32_semwait): Likewise.
+ * sem_destroy.c (sem_destroy): Likewise; also tightened the conditions
+ for semaphore destruction; in particular, a semaphore will not be
+ destroyed if it has waiters.
+ * sem_timedwait.c (sem_timedwait): Added cancel cleanup handler to
+ restore sema value when cancelled.
+ * sem_wait.c (sem_wait): Likewise.
+
+2004-10-21 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_mutex_unlock.c (pthread_mutex_unlock): Must use PulseEvent()
+ rather than SetEvent() to reset the event if there are no waiters.
+
+2004-10-19 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * sem_init.c (sem_init): New semaphore model based on the same idea
+ as mutexes, i.e. user space interlocked check to avoid
+ unnecessarily entering kernel space. Wraps the Win32 semaphore and
+ keeps it's own counter. Although the motivation to do this has existed
+ for a long time, credit goes to Alexander Terekhov for providing
+ the logic. I have deviated slightly from AT's logic to add the waiters
+ count, which has made the code more complicated by adding cancelation
+ cleanup. This also appears to have broken the VCE (C++ EH) version of
+ the library (the same problem as previously reported - see BUGS #2),
+ only apparently not fixable using the usual workaround, nor by turning
+ all optimisation off. The GCE version works fine, so it is presumed to
+ be a bug in MSVC++ 6.0. The cancelation exception is thrown and caught
+ correctly, but the cleanup class destructor is never called. The failing
+ test is tests\semaphore4.c.
+ * sem_wait.c (sem_wait): Implemented user space check model.
+ * sem_post.c (sem_post): Likewise.
+ * sem_trywait.c (sem_trywait): Likewise.
+ * sem_timedwait.c (sem_timedwait): Likewise.
+ * sem_post_multiple.c (sem_post_multiple): Likewise.
+ * sem_getvalue.c (sem_getvalue): Likewise.
+ * ptw32_semwait.c (ptw32_semwait): Likewise.
+ * implement.h (sem_t_): Add counter element.
+
+2004-10-15 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * implement.h (pthread_mutex_t_): Use an event in place of
+ the POSIX semaphore.
+ * pthread_mutex_init.c: Create the event; remove semaphore init.
+ * pthread_mutex_destroy.c: Delete the event.
+ * pthread_mutex_lock.c: Replace the semaphore wait with the event wait.
+ * pthread_mutex_trylock.c: Likewise.
+ * pthread_mutex_timedlock.c: Likewise.
+ * pthread_mutex_unlock.c: Set the event.
+
+2004-10-14 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_mutex_lock.c (pthread_mutex_lock): New algorithm using
+ Terekhov's xchg based variation of Drepper's cmpxchg model.
+ Theoretically, xchg uses fewer clock cycles than cmpxchg (using IA-32
+ as a reference), however, in my opinion bus locking dominates the
+ equation on smp systems, so the model with the least number of bus
+ lock operations in the execution path should win, which is Terekhov's
+ variant. On IA-32 uni-processor systems, it's faster to use the
+ CMPXCHG instruction without locking the bus than to use the XCHG
+ instruction, which always locks the bus. This makes the two variants
+ equal for the non-contended lock (fast lane) execution path on up
+ IA-32. Testing shows that the xchg variant is faster on up IA-32 as
+ well if the test forces higher lock contention frequency, even though
+ kernel calls should be dominating the times (on up IA-32, both
+ variants used CMPXCHG instructions and neither locked the bus).
+ * pthread_mutex_timedlock.c pthread_mutex_timedlock(): Similarly.
+ * pthread_mutex_trylock.c (pthread_mutex_trylock): Similarly.
+ * pthread_mutex_unlock.c (pthread_mutex_unlock): Similarly.
+ * ptw32_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. Idea suggested by Alexander Terekhov - see:
+ http://sources.redhat.com/ml/pthreads-win32/2003/msg00108.html
+ * pthread_mutex_timedlock.c pthread_mutex_timedlock(): Similarly.
+ * pthread_mutex_trylock.c (pthread_mutex_trylock): Similarly.
+ * pthread_mutex_unlock.c (pthread_mutex_unlock): Similarly.
+ * pthread_barrier_wait.c (pthread_barrier_wait): Use inlined version
+ of InterlockedCompareExchange() if possible - determined at
+ build-time.
+ * pthread_spin_destroy.c pthread_spin_destroy(): Likewise.
+ * pthread_spin_lock.c pthread_spin_lock():Likewise.
+ * pthread_spin_trylock.c (pthread_spin_trylock):Likewise.

+ * ptw32_InterlockedCompareExchange.c: Sets up macro for inlined use.
+ * implement.h (pthread_mutex_t_): Remove Critical Section element.
+ (PTW32_INTERLOCKED_COMPARE_EXCHANGE): Set to default non-inlined
+ version of InterlockedCompareExchange().
+ * private.c: Include ptw32_InterlockedCompareExchange.c first for
+ inlining.
+ * GNUmakefile: Add commandline option to use inlined
+ InterlockedCompareExchange().
+ * Makefile: Likewise.
+
+2004-09-27 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_mutex_lock.c (pthread_mutex_lock): Separate
+ PTHREAD_MUTEX_NORMAL logic since we do not need to keep or check some
+ state required by other mutex types; do not check mutex pointer arg
+ for validity - leave this to the system since we are only checking
+ for NULL pointers. This should improve speed of NORMAL mutexes and
+ marginally improve speed of other type.
+ * pthread_mutex_trylock.c (pthread_mutex_trylock): Likewise.
+ * pthread_mutex_unlock.c (pthread_mutex_unlock): Likewise; also avoid
+ entering the critical section for the no-waiters case, with approx.
+ 30% reduction in lock/unlock overhead for this case.
+ * pthread_mutex_timedlock.c (pthread_mutex_timedlock): Likewise; also
+ no longer keeps mutex if post-timeout second attempt succeeds - this
+ will assist applications that wish to impose strict lock deadlines,
+ rather than simply to escape from frozen locks.
+
+2004-09-09 Tristan Savatier <tristan at mpegtv.com>
+ * pthread.h (struct pthread_once_t_): Qualify the 'done' element
+ as 'volatile'.
+ * pthread_once.c: Concerned about possible race condition,
+ specifically on MPU systems re concurrent access to multibyte types.
+ [Maintainer's note: the race condition is harmless on SPU systems
+ and only a problem on MPU systems if concurrent access results in an
+ exception (presumably generated by a hardware interrupt). There are
+ other instances of similar harmless race conditions that have not
+ been identified as issues.]
+
+2004-09-09 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread.h: Declare additional types as volatile.

+
+ * pthread_join.c (pthread_join): Rewrite and re-order the conditional
+ tests in an attempt to improve efficiency and remove a race
+ condition.
+
+2004-08-23 Ross Johnson <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.

+ than pushing to stack.
+ * semaphore.h: Likewise.

+2003-09-14 Ross Johnson <rpj at callisto.canberra.edu.au>
+
+ * pthread_setschedparam.c (pthread_setschedparam): Attempt to map

+ levels between THREAD_PRIORITY_LOWEST/IDLE to THREAD_PRIORITY_LOWEST and

+ 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

+
+ * 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

+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

+ - 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

+ 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

+ 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>

+
+
+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

+ * pthread.h (_POSIX_SEM_VALUE_MAX): Defined.

+
+ * 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.

+ address to ptw32_interlocked_compare_exchange if it exists, or
+ our own ix86 specific implementation ptw32_InterlockedCompareExchange.
+ *private.c (ptw32_InterlockedCompareExchange): An
+ implementation of InterlockedCompareExchange() which is
+ specific to ix86; written directly in assembler for either
+ MSVC or GNU C; needed because Windows 95 doesn't support
+ InterlockedCompareExchange().
+
+ * sched.c (sched_get_priority_min): Extend to return
+ THREAD_PRIORITY_IDLE.
+ (sched_get_priority_max): Extend to return

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

+
+2001-08-23 Alexander Terekhov <TEREKHOV at de.ibm.com>
+
+ * condvar.c (pthread_cond_destroy): fix bug with

+
+2001-08-23 Phil Frisbie, Jr. <phil at hawksoft.com>
+
+ * tsd.c (pthread_getspecific): Preserve the last

+
+2001-07-18 Scott McCaskill <scott at magruder.org>
+
+ * mutex.c (pthread_mutexattr_init): Return ENOMEM

+
+2001-07-15 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * rwlock.c (pthread_rwlock_wrlock): Is allowed to be
+ a cancelation point; re-enable deferred cancelability
+ around the CV call.
+
+2001-07-10 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * barrier.c: Still more revamping. The exclusive access
+ mutex isn't really needed so it has been removed and replaced
+ by an InterlockedDecrement(). nSerial has been removed.
+ iStep is now dual-purpose. The process shared attribute
+ is now stored in the barrier struct.
+ * implement.h (pthread_barrier_t_): Lost some/gained one
+ elements.
+ * private.c (ptw32_threadStart): Removed some comments.
+
+2001-07-10 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * barrier.c: Revamped to fix the race condition. Two alternating
+ semaphores are used instead of the PulseEvent. Also improved
+ overall throughput by returning PTHREAD_BARRIER_SERIAL_THREAD
+ to the first waking thread.
+ * implement.h (pthread_barrier_t_): Revamped.
+
+2001-07-09 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * barrier.c: Fix several bugs in all routines. Now passes
+ tests/barrier5.c which is fairly rigorous. There is still
+ a non-optimal work-around for a race condition between
+ the barrier breeched event signal and event wait. Basically
+ the last (signalling) thread to hit the barrier yields
+ to allow any other threads, which may have lost the race,
+ to complete.
+
+2001-07-07 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * barrier.c: Changed synchronisation mechanism to a
+ Win32 manual reset Event and use PulseEvent to signal
+ waiting threads. If the implementation continued to use
+ a semaphore it would require a second semaphore and
+ some management to use them alternately as barriers. A
+ single semaphore allows threads to cascade from one barrier
+ through the next, leaving some threads blocked at the first.
+ * implement.h (pthread_barrier_t_): As per above.
+ * general: Made a number of other routines inlinable.
+
+2001-07-07 Ross Johnson <rpj at setup1.ise.canberra.edu.au>

+2001-07-01 Alexander Terekhov <TEREKHOV at de.ibm.com>
+
+ * condvar.c: Fixed lost signal bug reported by Timur Aydin
+ (taydin@snet.net).
+ [RPJ (me) didn't translate the original algorithm
+ correctly.]
+ * semaphore.c: Added sem_post_multiple; this is a useful
+ routine, but it doesn't appear to be standard. For now it's
+ not an exported function.
+
+2001-06-25 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * create.c (pthread_create): Add priority inheritance
+ attributes.
+ * mutex.c (pthread_mutex_lock): Remove some overhead for
+ PTHREAD_MUTEX_NORMAL mutex types. Specifically, avoid
+ calling pthread_self() and pthread_equal() to check/set
+ the mutex owner. Introduce a new pseudo owner for this
+ type. Test results suggest increases in speed of up to
+ 90% for non-blocking locks.
+ This is the default type of mutex used internally by other
+ synchronising objects, ie. condition variables and
+ read-write locks. The test rwlock7.c shows about a
+ 30-35% speed increase over snapshot 2001-06-06. The
+ price of this is that the application developer
+ must ensure correct behaviour, or explicitly set the
+ mutex to a safer type such as PTHREAD_MUTEX_ERRORCHECK.
+ For example, PTHREAD_MUTEX_NORMAL (or PTHREAD_MUTEX_DEFAULT)
+ type mutexes will not return an error if a thread which is not
+ the owner calls pthread_mutex_unlock. The call will succeed
+ in unlocking the mutex if it is currently locked, but a
+ subsequent unlock by the true owner will then fail with EPERM.
+ This is however consistent with some other implementations.
+ (pthread_mutex_unlock): Likewise.
+ (pthread_mutex_trylock): Likewise.
+ (pthread_mutex_destroy): Likewise.
+ * attr.c (pthread_attr_init): PTHREAD_EXPLICIT_SCHED is the
+ default inheritance attribute; THREAD_PRIORITY_NORMAL is
+ the default priority for new threads.
+ * sched.c (pthread_attr_setschedpolicy): Added routine.
+ (pthread_attr_getschedpolicy): Added routine.
+ (pthread_attr_setinheritsched): Added routine.
+ (pthread_attr_getinheritsched): Added routine.
+ * pthread.h (sched_rr_set_interval): Added as a macro;
+ returns -1 with errno set to ENOSYS.
+
+2001-06-23 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ *sched.c (pthread_attr_setschedparam): Add priority range
+ check.
+ (sched_setscheduler): New function; checks for a valid
+ pid and policy; checks for permission to set information
+ in the target process; expects pid to be a Win32 process ID,
+ not a process handle; the only scheduler policy allowed is
+ SCHED_OTHER.
+ (sched_getscheduler): Likewise, but checks for permission
+ to query.
+ * pthread.h (SCHED_*): Moved to sched.h as defined in the
+ POSIX standard.
+ * sched.h (SCHED_*): Moved from pthread.h.
+ (pid_t): Defined if necessary.
+ (sched_setscheduler): Defined.
+ (sched_getscheduler): Defined.

+
+2001-06-18 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * Made organisational-only changes to UWIN additions.

+ * create.c: Likewise.
+ * pthread.h: Likewise.
+ * misc.c: Likewise.
+ * exit.c: Likewise.
+ * private.c: Likewise.
+ * implement.h: Likewise.
+ There is some room at the start of struct pthread_t_
+ to implement the signal semantics in UWIN's posix.dll
+ although this is not yet complete.
+ * Nmakefile: Compatible with UWIN's Nmake utility.
+ * Nmakefile.tests: Likewise - for running the tests.
+
+2001-06-08 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * semaphore.h (sem_t): Fixed for compile and test.
+ * implement.h (sem_t_): Likewise.
+ * semaphore.c: Likewise.
+ * private.c (ptw32_sem_timedwait): Updated to use new
+ opaque sem_t.
+
+2001-06-06 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * semaphore.h (sem_t): Is now an opaque pointer;
+ moved actual definition to implement.h.
+ * implement.h (sem_t_): Move here from semaphore.h;
+ was the definition of sem_t.
+ * semaphore.c: Wherever necessary, changed use of sem
+ from that of a pointer to a pointer-pointer; added
+ extra checks for a valid sem_t; NULL sem_t when
+ it is destroyed; added extra checks when creating
+ and destroying sem_t elements in the NEED_SEM
+ code branches; changed from using a pthread_mutex_t
+ ((*sem)->mutex) to CRITICAL_SECTION ((*sem)->sem_lock_cs)
+ in NEED_SEM branches for access serialisation.
+
+2001-06-06 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * mutex.c (pthread_mutexattr_init): Remove
+ ptw32_mutex_default_kind.
+
+2001-06-05 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * nonportable.c (pthread_mutex_setdefaultkind_np):
+ Remove - should not have been included in the first place.
+ (pthread_mutex_getdefaultkind_np): Likewise.
+ * global.c (ptw32_mutex_default_kind): Likewise.
+ * mutex.c (pthread_mutex_init): Remove use of

+ * pthread.h (pthread_mutex_setdefaultkind_np): Likewise.
+ (pthread_mutex_getdefaultkind_np): Likewise.
+ * pthread.def (pthread_mutexattr_setkind_np): Added.
+ (pthread_mutexattr_getkind_np): Likewise.
+
+ * README: Many changes that should have gone in before
+ the last snapshot.
+ * README.NONPORTABLE: New - referred to by ANNOUNCE
+ but never created; documents the non-portable routines
+ included in the library - moved from README with new
+ routines added.
+ * ANNOUNCE (pthread_mutexattr_setkind_np): Added to
+ compliance list.
+ (pthread_mutexattr_getkind_np): Likewise.
+
+2001-06-04 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * condvar.c: Add original description of the algorithm as
+ developed by Terekhov and Thomas, plus reference to
+ README.CV.
+
+2001-06-03 Alexander Terekhov <TEREKHOV at de.ibm.com>, Louis Thomas <lthomas at arbitrade.com>
+
+ * condvar.c (pthread_cond_init): Completely revamped.
+ (pthread_cond_destroy): Likewise.
+ (ptw32_cond_wait_cleanup): Likewise.

+ (pthread_cond_broadcast): Likewise.
+ * implement.h (pthread_cond_t_): Revamped.
+ * README.CV: New; explanation of the above changes.
+
+2001-05-30 Ross Johnson <rpj at setup1.ise.canberra.edu.au>
+
+ * pthread.h (rand_r): Fake using _seed argument to quell
+ compiler warning (compiler should optimise this away later).
+
+ * GNUmakefile (OPT): Leave symbolic information out of the library
+ and increase optimisation level - for smaller faster prebuilt
+ dlls.
+
+2001-05-29 Milan Gardian <Milan.Gardian at LEIBINGER.com>
+
+ * Makefile: fix typo.
+ * pthreads.h: Fix problems with stdcall/cdecl conventions, in particular
+ remove the need for PT_STDCALL everywhere; remove warning supression.
+ * (errno): Fix the longstanding "inconsistent dll linkage" problem
+ with errno; now also works with /MD debugging libs -
+ warnings emerged when compiling pthreads library with /MD (or /MDd)
+ compiler switch, instead of /MT (or /MTd) (i.e. when compiling pthreads
+ using Multithreaded DLL CRT instead of Multithreaded statically linked
+ CRT).
+ * create.c (pthread_create): Likewise; fix typo.
+ * private.c (ptw32_threadStart): Eliminate use of terminate() which doesn't
+ throw exceptions.
+ * Remove unnecessary #includes from a number of modules -
+ [I had to #include malloc.h in implement.h for gcc - rpj].
+
+2001-05-29 Thomas Pfaff <tpfaff at gmx.net>
+
+ * pthread.h (PTHREAD_MUTEX_DEFAULT): New; equivalent to
+ PTHREAD_MUTEX_DEFAULT_NP.
+ * (PTHREAD_MUTEX_NORMAL): Similarly.
+ * (PTHREAD_MUTEX_ERRORCHECK): Similarly.
+ * (PTHREAD_MUTEX_RECURSIVE): Similarly.
+ * (pthread_mutex_setdefaultkind_np): New; Linux compatibility stub
+ for pthread_mutexattr_settype.
+ * (pthread_mutexattr_getkind_np): New; Linux compatibility stub
+ for pthread_mutexattr_gettype.
+ * mutex.c (pthread_mutexattr_settype): New; allow
+ the following types of mutex:
+ PTHREAD_MUTEX_DEFAULT_NP
+ PTHREAD_MUTEX_NORMAL_NP
+ PTHREAD_MUTEX_ERRORCHECK_NP
+ PTHREAD_MUTEX_RECURSIVE_NP
+ * Note that PTHREAD_MUTEX_DEFAULT is equivalent to
+ PTHREAD_MUTEX_NORMAL - ie. mutexes should no longer
+ be recursive by default, and a thread will deadlock if it
+ tries to relock a mutex it already owns. This is inline with
+ other pthreads implementations.
+ * (pthread_mutex_lock): Process the lock request
+ according to the mutex type.
+ * (pthread_mutex_init): Eliminate use of Win32 mutexes as the
+ basis of POSIX mutexes - instead, a combination of one critical section
+ and one semaphore are used in conjunction with Win32 Interlocked* routines.
+ * (pthread_mutex_destroy): Likewise.
+ * (pthread_mutex_lock): Likewise.
+ * (pthread_mutex_trylock): Likewise.
+ * (pthread_mutex_unlock): Likewise.
+ * Use longjmp/setjmp to implement cancelation when building the library
+ using a C compiler which doesn't support exceptions, e.g. gcc -x c (note
+ that gcc -x c++ uses exceptions).
+ * Also fixed some of the same typos and eliminated PT_STDCALL as
+ Milan Gardian's patches above.
+
+2001-02-07 Alexander Terekhov <TEREKHOV at de.ibm.com>
+
+ * rwlock.c: Revamped.
+ * implement.h (pthread_rwlock_t_): Redefined.
+ This implementation does not have reader/writer starvation problem.
+ Rwlock attempts to behave more like a normal mutex with
+ races and scheduling policy determining who is more important;
+ It also supports recursive locking,
+ has less synchronization overhead (no broadcasts at all,
+ readers are not blocked on any condition variable) and seem to
+ be faster than the current implementation [W98 appears to be
+ approximately 15 percent faster at least - on top of speed increase
+ from Thomas Pfaff's changes to mutex.c - rpj].
+
+2000-12-29 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * Makefile: Back-out "for" loops which don't work.
+
+ * GNUmakefile: Remove the fake.a target; add the "realclean"
+ target; don't remove built libs under the "clean" target.
+
+ * config.h: Add a guard against multiple inclusion.
+
+ * semaphore.h: Add some defines from config.h to make
+ semaphore.h independent of config.h when building apps.

+ * pthread.h (_errno): Back-out previous fix until we know how to
+ fix it properly.
+
+ * implement.h (lockCount): Add missing element to pthread_mutex_t_.
+
+ * sync.c (pthread_join): Spelling fix in comment.
+
+ * private.c (ptw32_threadStart): Reset original termination
+ function (C++).
+ (ptw32_threadStart): Cleanup detached threads early in case
+ the library is statically linked.
+ (ptw32_callUserDestroyRoutines): Remove [SEH] __try block from
+ destructor call so that unhandled exceptions will be passed through
+ to the system; call terminate() from [C++] try block for the same
+ reason.
+
+ * tsd.c (pthread_getspecific): Add comment.
+
+ * mutex.c (pthread_mutex_init): Initialise new elements in
+ pthread_mutex_t.
+ (pthread_mutex_unlock): Invert "pthread_equal()" test.
+
+2000-12-28 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * semaphore.c (mode_t): Use ifndef HAVE_MODE_T to include definition.
+
+ * config.h.in (HAVE_MODE_T): Added.
+ (_UWIN): Start adding defines for the UWIN package.
+
+ * private.c (ptw32_threadStart): Unhandled exceptions are
+ now passed through to the system to deal with. This is consistent
+ with normal Windows behaviour. C++ applications may use
+ set_terminate() to override the default behaviour which is
+ to call ptw32_terminate(). Ptw32_terminate() cleans up some
+ POSIX thread stuff before calling the system default function
+ which calls abort(). The users termination function should conform
+ to standard C++ semantics which is to not return. It should
+ exit the thread (call pthread_exit()) or exit the application.
+ * private.c (ptw32_terminate): Added as the default set_terminate()
+ function. It calls the system default function after cleaning up
+ some POSIX thread stuff.
+
+ * implement.h (ptw32_try_enter_critical_section): Move
+ declaration.
+ * global.c (ptw32_try_enter_critical_section): Moved
+ from dll.c.
+ * dll.c: Move process and thread attach/detach code into
+ functions in nonportable.c.
+ * nonportable.c (pthread_win32_process_attach_np): Process
+ attach code from dll.c is now available to static linked
+ applications.
+ * nonportable.c (pthread_win32_process_detach_np): Likewise.
+ * nonportable.c (pthread_win32_thread_attach_np): Likewise.

+ 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

+
+2000-09-06 Ross Johnson <rpj at special.ise.canberra.edu.au>

+ exception selectors by ptw32_throw().
+
+ * Several: Fix typos from scripted edit session
+ yesterday.
+
+ * nonportable.c (pthread_mutexattr_setforcecs_np):
+ Moved this function from mutex.c.
+ (pthread_getw32threadhandle_np): New function to
+ return the win32 thread handle that the POSIX
+ thread is using.
+ * mutex.c (pthread_mutexattr_setforcecs_np):
+ Moved to new file "nonportable.c".
+
+ * pthread.h (PTW32_BUILD): Only redefine __except
+ and catch compiler keywords if we aren't building
+ the library (ie. PTW32_BUILD is not defined) -
+ this is safer than defining and then undefining
+ if not building the library.
+ * implement.h: Remove __except and catch undefines.
+ * Makefile (CFLAGS): Define PTW32_BUILD.
+ * GNUmakefile (CFLAGS): Define PTW32_BUILD.
+
+ * All appropriate: Change Pthread_exception* to
+ ptw32_exception* to be consistent with internal
+ identifier naming.
+
+ * private.c (ptw32_throw): New function to provide
+ a generic exception throw for all internal
+ exceptions and EH schemes.
+ (ptw32_threadStart): pthread_exit() value is now
+ returned via the thread structure exitStatus
+ element.
+ * exit.c (pthread_exit): pthread_exit() value is now

+ element.
+ * cancel.c (ptw32_cancel_self): Now uses ptw32_throw.
+ (pthread_setcancelstate): Ditto.
+ (pthread_setcanceltype): Ditto.
+ (pthread_testcancel): Ditto.
+ (pthread_cancel): Ditto.
+ * misc.c (CancelableWait): Ditto.

+
+2000-08-17 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * All applicable: Change _pthread_ prefix to
+ ptw32_ prefix to remove leading underscores
+ from private library identifiers (single
+ and double leading underscores are reserved in the
+ ANSI C standard for compiler implementations).
+
+ * tsd.c (pthread_create_key): Initialise temporary
+ key before returning it's address to avoid race
+ conditions.
+
+2000-08-13 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * errno.c: Add _MD precompile condition; thus far
+ had no effect when using /MD compile option but I
+ thnk it should be there.
+
+ * exit.c: Add __cplusplus to various #if lines;
+ was compiling SEH code even when VC++ had
+ C++ compile options.
+
+ * private.c: ditto.
+
+ * create.c (pthread_create): Add PT_STDCALL macro to
+ function pointer arg in _beginthread().
+
+ * pthread.h: PT_STDCALL really does need to be defined
+ in both this and impliment.h; don't set it to __cdecl
+ - this macro is only used to extend function pointer
+ casting for functions that will be passed as parameters.
+ (~PThreadCleanup): add cast and group expression.
+ (_errno): Add _MD compile conditional.
+ (PtW32NoCatchWarn): Change pragma message.
+
+ * implement.h: Move and change PT_STDCALL define.
+
+ * need_errno.h: Add _MD to compilation conditional.
+
+ * GNUmakefile: Substantial rewrite for new naming
+ convention; set for nil optimisation (turn it up
+ when we have a working library build; add target
+ "fake.a" to build a libpthreadw32.a from the VC++
+ built DLL pthreadVCE.dll.
+
+ * pthread.def (LIBRARY): Don't specify in the .def
+ file - it is specified on the linker command line
+ since we now use the same .def file for variously
+ named .dlls.
+
+ * Makefile: Substantial rewrite for new naming
+ convention; default nmake target only issues a
+ help message; run nmake with specific target
+ corresponding to the EH scheme being used.
+
+ * README: Update information; add naming convention
+ explanation.
+
+ * ANNOUNCE: Update information.
+
+2000-08-12 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h: Add compile-time message when using
+ MSC_VER compiler and C++ EH to warn application
+ programmers to use PtW32Catch instead of catch(...)
+ if they want cancelation and pthread_exit to work.
+
+ * implement.h: Remove #include <semaphore.h>; we
+ use our own local semaphore.h.
+
+2000-08-10 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * cleanup.c (pthread_pop_cleanup): Remove _pthread
+ prefix from __except and catch keywords; implement.h
+ now simply undefines ptw32__except and
+ ptw32_catch if defined; VC++ was not textually
+ substituting ptw32_catch etc back to catch as
+ it was redefined; the reason for using the prefixed
+ version was to make it clear that it was not using
+ the pthread.h redefined catch keyword.
+
+ * private.c (ptw32_threadStart): Ditto.
+ (ptw32_callUserDestroyRoutines): Ditto.
+
+ * implement.h (ptw32__except): Remove #define.
+ (ptw32_catch): Remove #define.
+
+ * GNUmakefile (pthread.a): New target to build
+ libpthread32.a from pthread.dll using dlltool.
+
+ * buildlib.bat: Duplicate cl commands with args to
+ build C++ EH version of pthread.dll; use of .bat
+ files is redundant now that nmake compatible
+ Makefile is included; used as a kludge only now.
+
+ * Makefile: Localise some macros and fix up the clean:
+ target to extend it and work properly.
+
+ * CONTRIBUTORS: Add contributors.
+
+ * ANNOUNCE: Updated.
+
+ * README: Updated.
+
+2000-08-06 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h: Remove #warning - VC++ doesn't accept it.
+
+2000-08-05 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h (PtW32CatchAll): Add macro. When compiling
+ applications using VC++ with C++ EH rather than SEH
+ 'PtW32CatchAll' must be used in place of any 'catch( ... )'
+ if the application wants pthread cancelation or
+ pthread_exit() to work.
+
+2000-08-03 Ross Johnson <rpj at special.ise.canberra.edu.au>
+
+ * pthread.h: Add a base class ptw32_exception for

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

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

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

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

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

+ that the critical section works and return an error if not.
+
+2000-01-07 Ross Johnson <rpj at special.ise.canberra.edu.au>

+ (ptw32_processInitialize): Remove initialisation of
+ ptw32_exception_services which is no longer needed.
+
+ * pthread.h (ptw32_exception_services): Remove extern.
+ (ptw32_get_exception_services_code): Add function prototype;
+ use this to return EXCEPTION_PTW32_SERVICES value instead of

+
+ * global.c (ptw32_exception_services): Remove declaration.
+
+1999-11-22 Ross Johnson <rpj at special.ise.canberra.edu.au>

+ (ptw32_processInitialize): Init new constant ptw32_exception_services.
+
+ * create.c (pthread_create): Initialise thread's cancelLock

+
+ * private.c: Ditto.
+
+ * pthread.h (catch): Redefine 'catch' so that C++ applications

+ (__except): ditto for __except.
+
+ * implement.h (ptw32_catch): Define internal version

+
+1999-11-21 Jason Nye <jnye at nbnet.nb.ca>, Erik Hensema <erik.hensema at group2000.nl>
+
+ * cancel.c (ptw32_cancel_self): New; part of the async

+
+1999-11-13 Erik Hensema <erik.hensema at group2000.nl>

+
+1999-11-10 Todd Owen <towen at lucidcalm.dropbear.id.au>
+
+ * dll.c (dllMain): Free kernel32 ASAP.
+ If TryEnterCriticalSection is not being used, then free
+ the kernel32.dll handle now, rather than leaving it until
+ DLL_PROCESS_DETACH.
+
+ Note: this is not a pedantic exercise in freeing unused
+ resources! It is a work-around for a bug in Windows 95
+ (see microsoft knowledge base article, Q187684) which
+ does Bad Things when FreeLibrary is called within
+ the DLL_PROCESS_DETACH code, in certain situations.
+ Since w95 just happens to be a platform which does not
+ provide TryEnterCriticalSection, the bug will be
+ effortlessly avoided.

+
+Tue Jan 19 18:27:42 1999 Scott Lightner <scott at curriculum.com>
+
+ * private.c (ptw32_sem_timedwait): 'abstime' arg really is
+ absolute time. Calculate relative time to wait from current

+ pthreadCancelableTimedWait().
+
+Tue Jan 19 10:27:39 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * pthread.h (pthread_mutexattr_setforcecs_np): New prototype.
+
+ * mutex.c (pthread_mutexattr_init): Init 'pshared' and 'forcecs'
+ attributes to 0.
+ (pthread_mutexattr_setforcecs_np): New function (not portable).
+
+ * pthread.h (pthread_mutex_t):
+ Add 'mutex' element. Set to NULL in PTHREAD_MUTEX_INITIALIZER.
+ The pthread_mutex_*() routines will try to optimise performance
+ by choosing either mutexes or critical sections as the basis
+ for pthread mutexes for each indevidual mutex.
+ (pthread_mutexattr_t_): Add 'forcecs' element.
+ Some applications may choose to force use of critical sections
+ if they know that:-
+ the mutex is PROCESS_PRIVATE and,
+ either the OS supports TryEnterCriticalSection() or
+ pthread_mutex_trylock() will never be called on the mutex.
+ This attribute will be setable via a non-portable routine.
+
+ Note: We don't yet support PROCESS_SHARED mutexes, so the
+ implementation as it stands will default to Win32 mutexes only if
+ the OS doesn't support TryEnterCriticalSection. On Win9x, and early
+ versions of NT 'forcecs' will need to be set in order to get
+ critical section based mutexes.
+
+Sun Jan 17 12:01:26 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * pthread.h (PTHREAD_MUTEX_INITIALIZER): Init new 'staticinit'
+ value to '1' and existing 'valid' value to '1'.
+
+ * global.c (ptw32_mutex_test_init_lock): Add.
+
+ * implement.h (ptw32_mutex_test_init_lock.): Add extern.
+
+ * private.c (ptw32_processInitialize): Init critical section for
+ global lock used by _mutex_check_need_init().
+ (ptw32_processTerminate): Ditto (:s/Init/Destroy/).
+
+ * dll.c (dllMain): Move call to FreeLibrary() so that it is only
+ called once when the process detaches.
+
+ * mutex.c (_mutex_check_need_init): New static function to test
+ and init PTHREAD_MUTEX_INITIALIZER mutexes. Provides serialised
+ access to the internal state of the uninitialised static mutex.
+ Called from pthread_mutex_trylock() and pthread_mutex_lock() which
+ do a quick unguarded test to check if _mutex_check_need_init()
+ needs to be called. This is safe as the test is conservative
+ and is repeated inside the guarded section of
+ _mutex_check_need_init(). Thus in all calls except the first
+ calls to lock static mutexes, the additional overhead to lock any
+ mutex is a single memory fetch and test for zero.
+
+ * pthread.h (pthread_mutex_t_): Add 'staticinit' member. Mutexes
+ initialised by PTHREAD_MUTEX_INITIALIZER aren't really initialised
+ until the first attempt to lock it. Using the 'valid'
+ flag (which flags the mutex as destroyed or not) to record this
+ information would be messy. It is possible for a statically
+ initialised mutex such as this to be destroyed before ever being
+ used.
+
+ * mutex.c (pthread_mutex_trylock): Call _mutex_check_need_init()
+ to test/init PTHREAD_MUTEX_INITIALIZER mutexes.
+ (pthread_mutex_lock): Ditto.
+ (pthread_mutex_unlock): Add check to ensure we don't try to unlock
+ an unitialised static mutex.
+ (pthread_mutex_destroy): Add check to ensure we don't try to delete
+ a critical section that we never created. Allows us to destroy
+ a static mutex that has never been locked (and hence initialised).
+ (pthread_mutex_init): Set 'staticinit' flag to 0 for the new mutex.
+
+Sun Jan 17 12:01:26 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * private.c (ptw32_sem_timedwait): Move from semaphore.c.
+
+ * semaphore.c : Remove redundant #includes.
+ (ptw32_sem_timedwait): Move to private.c.
+ (sem_wait): Add missing abstime arg to pthreadCancelableWait() call.
+
+Fri Jan 15 23:38:05 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * condvar.c (cond_timedwait): Remove comment.
+
+Fri Jan 15 15:41:28 1999 Ross Johnson <rpj at swan.canberra.edu.au>
+
+ * pthread.h: Add new 'abstime' arg to pthreadCancelableWait()
+ prototype.
+
+ * condvar.c (cond_timedwait): New generalised function called by
+ both pthread_cond_wait() and pthread_cond_timedwait(). This is
+ essentially pthread_cond_wait() renamed and modified to add the
+ 'abstime' arg and call the new ptw32_sem_timedwait() instead of
+ sem_wait().
+ (pthread_cond_wait): Now just calls the internal static
+ function cond_timedwait() with an INFINITE wait.
+ (pthread_cond_timedwait): Now implemented. Calls the internal
+ static function cond_timedwait().
+
+ * implement.h (ptw32_sem_timedwait): New internal function
+ prototype.
+
+ * misc.c (pthreadCancelableWait): Added new 'abstime' argument
+ to allow shorter than INFINITE wait.
+
+ * semaphore.c (ptw32_sem_timedwait): New function for internal
+ use. This is essentially sem_wait() modified to add the
+ 'abstime' arg and call the modified (see above)
+ pthreadCancelableWait().
+
+Thu Jan 14 14:27:13 1999 Ross Johnson <rpj at swan.canberra.edu.au>
+
+ * cleanup.c: Correct _cplusplus to __cplusplus wherever used.
+
+ * Makefile.in: Add CC=g++ and add -fhandle-exceptions to CFLAGS.
+ The derived Makefile will compile all units of the package as C++
+ so that those which include try/catch exception handling should work
+ properly. The package should compile ok if CC=gcc, however, exception
+ handling will not be included and thus thread cancellation, for
+ example, will not work.
+
+ * cleanup.c (ptw32_pop_cleanup): Add #warning to compile this
+ file as C++ if using a cygwin32 environment. Perhaps the whole package
+ should be compiled using g++ under cygwin.
+
+ * private.c (ptw32_threadStart): Change #error directive
+ into #warning and bracket for __CYGWIN__ and derivative compilers.
+
+Wed Jan 13 09:34:52 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+
+ * build.bat: Delete old binaries before compiling/linking.
+
+Tue Jan 12 09:58:38 1999 Tor Lillqvist <tml at iki.fi>
+
+ * dll.c: The Microsoft compiler pragmas probably are more
+ appropriately protected by _MSC_VER than by _WIN32.
+
+ * pthread.h: Define ETIMEDOUT. This should be returned by
+ pthread_cond_timedwait which is not implemented yet as of
+ snapshot-1999-01-04-1305. It was implemented in the older version.
+ The Microsoft compiler pragmas probably are more appropriately
+ protected by _MSC_VER than by _WIN32.
+
+ * pthread.def: pthread_mutex_destroy was missing from the def file
+
+ * condvar.c (pthread_cond_broadcast): Ensure we only wait on threads
+ if there were any waiting on the condition.
+ I think pthread_cond_broadcast should do the WaitForSingleObject
+ only if cv->waiters > 0? Otherwise it seems to hang, at least in the
+ testg thread program from glib.
+
+Tue Jan 12 09:58:38 1999 Ross Johnson <rpj at ixobrychus.canberra.edu.au>
+

+=============================================================================
+
+Q 1 What is it?
+---
+
+Pthreads-win32 is an Open Source Software implementation of the
+Threads component of the POSIX 1003.1c 1995 Standard for Microsoft's
+Win32 environment. Some functions from POSIX 1003.1b are also
+supported including semaphores. Other related functions include
+the set of read-write lock functions. The library also supports
+some of the functionality of the Open Group's Single Unix
+specification, version 2, namely mutex types.
+
+See the file "ANNOUNCE" for more information including standards
+conformance details and list of supported routines.
+
+
+------------------------------------------------------------------------------
+
+Q 2 Which of the several dll versions do I use?
+--- or,
+ What are all these pthread*.dll and pthread*.lib files?
+
+Simply, you only use one of them, but you need to choose carefully.
+
+The most important choice you need to make is whether to use a
+version that uses exceptions internally, or not (there are versions
+of the library that use exceptions as part of the thread
+cancelation and cleanup implementation, and one that uses
+setjmp/longjmp instead).
+
+There is some contension amongst POSIX threads experts as
+to how POSIX threads cancelation and exit should work
+with languages that include exceptions and handlers, e.g.
+C++ and even C (Microsoft's Structured Exceptions).
+
+The issue is: should cancelation of a thread in, say,
+a C++ application cause object destructors and C++ exception
+handlers to be invoked as the stack unwinds during thread
+exit, or not?
+
+There seems to be more opinion in favour of using the
+standard C version of the library (no EH) with C++ applications
+since this appears to be the assumption commercial pthreads
+implementations make. Therefore, if you use an EH version
+of pthreads-win32 then you may be under the illusion that
+your application will be portable, when in fact it is likely to
+behave very differently linked with other pthreads libraries.
+
+Now you may be asking: why have you kept the EH versions of
+the library?
+
+There are a couple of reasons:
+- there is division amongst the experts and so the code may
+ be needed in the future. (Yes, it's in the repository and we
+ can get it out anytime in the future, but ...)
+- pthreads-win32 is one of the few implementations, and possibly
+ the only freely available one, that has EH versions. It may be
+ useful to people who want to play with or study application
+ behaviour under these conditions.
+
+
+------------------------------------------------------------------------------
+
+Q 3 What is the library naming convention?
+---
+
+Because the library is being built using various exception
+handling schemes and compilers - and because the library
+may not work reliably if these are mixed in an application,
+each different version of the library has it's own name.
+
+Note 1: the incompatibility is really between EH implementations
+of the different compilers. It should be possible to use the
+standard C version from either compiler with C++ applications
+built with a different compiler. If you use an EH version of
+the library, then you must use the same compiler for the
+application. This is another complication and dependency that
+can be avoided by using only the standard C library version.
+
+Note 2: if you use a standard C pthread*.dll with a C++
+application, then any functions that you define that are
+intended to be called via pthread_cleanup_push() must be
+__cdecl.
+
+Note 3: the intention is to also name either the VC or GC
+version (it should be arbitrary) as pthread.dll, including
+pthread.lib and libpthread.a as appropriate.
+
+In general:
+ pthread[VG]{SE,CE,C}.dll
+ pthread[VG]{SE,CE,C}.lib
+
+where:
+ [VG] indicates the compiler
+ V - MS VC
+ G - GNU C
+
+ {SE,CE,C} indicates the exception handling scheme
+ SE - Structured EH
+ CE - C++ EH
+ C - no exceptions - uses setjmp/longjmp
+
+For example:
+ pthreadVSE.dll (MSVC/SEH)
+ pthreadGCE.dll (GNUC/C++ EH)
+ pthreadGC.dll (GNUC/not dependent on exceptions)
+
+The GNU library archive file names have changed to:
+
+ libpthreadGCE.a
+ libpthreadGC.a
+
+
+------------------------------------------------------------------------------
+
+Q 4 Cleanup code default style or: it used to work when I built
+--- the library myself, but now it doesn't - why?
+
+Up to and including snapshot 2001-07-12, if not defined, the cleanup
+style was determined automatically from the compiler used, and one
+of the following was defined accordingly:
+
+ __CLEANUP_SEH MSVC only
+ __CLEANUP_CXX C++, including MSVC++, GNU G++
+ __CLEANUP_C C, including GNU GCC, not MSVC
+
+These defines determine the style of cleanup (see pthread.h) and,
+most importantly, the way that cancelation and thread exit (via
+pthread_exit) is performed (see the routine ptw32_throw() in private.c).
+
+In short, the exceptions versions of the library throw an exception
+when a thread is canceled or exits (via pthread_exit()), which is
+caught by a handler in the thread startup routine, so that the
+the correct stack unwinding occurs regardless of where the thread
+is when it's canceled or exits via pthread_exit().
+
+After snapshot 2001-07-12, unless your build explicitly defines (e.g.
+via a compiler option) __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then
+the build now ALWAYS defaults to __CLEANUP_C style cleanup. This style
+uses setjmp/longjmp in the cancelation and pthread_exit implementations,
+and therefore won't do stack unwinding even when linked to applications
+that have it (e.g. C++ apps). This is for consistency with most/all
+commercial Unix POSIX threads implementations.
+
+Although it was not clearly documented before, it is still necessary to
+build your application using the same __CLEANUP_* define as was
+used for the version of the library that you link with, so that the
+correct parts of pthread.h are included. That is, the possible
+defines require the following library versions:
+
+ __CLEANUP_SEH pthreadVSE.dll
+ __CLEANUP_CXX pthreadVCE.dll or pthreadGCE.dll
+ __CLEANUP_C pthreadVC.dll or pthreadGC.dll
+
+THE POINT OF ALL THIS IS: if you have not been defining one of these
+explicitly, then the defaults have been set according to the compiler
+and language you are using, as described at the top of this
+section.
+
+THIS NOW CHANGES, as has been explained above. For example:
+
+If you were building your application with MSVC++ i.e. using C++
+exceptions (rather than SEH) and not explicitly defining one of
+__CLEANUP_*, then __CLEANUP_C++ was defined for you in pthread.h.
+You should have been linking with pthreadVCE.dll, which does
+stack unwinding.
+
+If you now build your application as you had before, pthread.h will now
+set __CLEANUP_C as the default style, and you will need to link
+with pthreadVC.dll. Stack unwinding will now NOT occur when a
+thread is canceled, nor when the thread calls pthread_exit().
+
+Your application will now most likely behave differently to previous
+versions, and in non-obvious ways. Most likely is that local
+objects may not be destroyed or cleaned up after a thread
+is canceled.
+
+If you want the same behaviour as before, then you must now define
+__CLEANUP_C++ explicitly using a compiler option and link with
+pthreadVCE.dll as you did before.
+
+
+------------------------------------------------------------------------------
+
+Q 5 Why is the default library version now less exception-friendly?
+---
+
+Because most commercial Unix POSIX threads implementations don't allow you to
+choose to have stack unwinding. (Compaq's TRU64 Unix is possibly an exception.)
+
+Therefore, providing it in pthread-win32 as a default could be dangerous
+and non-portable. We still provide the choice but you must now consciously
+make it.
+
+WHY NOT REMOVE THE EXCEPTIONS VERSIONS OF THE LIBRARY ALTOGETHER?
+There are a few reasons:
+- because there are well respected POSIX threads people who believe
+ that POSIX threads implementations should be exceptions-aware and
+ do the expected thing in that context. (There are equally respected
+ people who believe it should not be easily accessible, if it's there
+ at all.)
+- because pthreads-win32 is one of the few implementations that has
+ the choice, perhaps the only freely available one, and so offers
+ a laboratory to people who may want to explore the effects;
+- although the code will always be around somewhere for anyone who
+ wants it, once it's removed from the current version it will not be
+ nearly as visible to people who may have a use for it.
+
+
+------------------------------------------------------------------------------
+
+Q 6 Should I use Cygwin or Mingw32 as a development environment?
+---
+
+Important: see Q7 also.
+
+Use Mingw32 with the MSVCRT library to build applications that use
+the pthreads DLL.
+
+Cygwin's own internal support for POSIX threads is growing.
+Consult that project's documentation for more information.
+
+------------------------------------------------------------------------------
+
+Q 7 Now that pthreads-win32 builds under Mingw32, why do I get
+--- memory access violations (segfaults)?
+
+The latest Mingw32 package has thread-safe exception handling (see Q10).
+Also, see Q6 above.
+
+------------------------------------------------------------------------------
+
+Q 8 How do I use pthread.dll for Win32 (Visual C++ 5.0)
+---
+
+>
+> I'm a "rookie" when it comes to your pthread implementation. I'm currently
+> desperately trying to install the prebuilt .dll file into my MSVC compiler.
+> Could you please provide me with explicit instructions on how to do this (or
+> direct me to a resource(s) where I can acquire such information)?
+>
+> Thank you,
+>
+
+You should have a .dll, .lib, .def, and three .h files. It is recommended
+that you use pthreadVC.dll, rather than pthreadVCE.dll or pthreadVSE.dll
+(see Q2 above).
+
+The .dll can go in any directory listed in your PATH environment
+variable, so putting it into C:\WINDOWS should work.
+
+The .lib file can go in any directory listed in your LIB environment
+variable.
+
+The .h files can go in any directory listed in your INCLUDE
+environment variable.
+
+Or you might prefer to put the .lib and .h files into a new directory
+and add its path to LIB and INCLUDE. You can probably do this easiest
+by editing the file:-
+
+C:\Program Files\DevStudio\vc\bin\vcvars32.bat
+
+The .def file isn't used by anything in the pre-compiled version but
+is included for information.
+
+Cheers.

+> calls work.
+
+The answer to your first question is, normal POSIX behaviour would
+be to asynchronously cancel the thread. However, even that doesn't
+guarantee cancelation as the standard only says it should be
+cancelled as soon as possible.
+
+Snapshot 99-11-02 or earlier only partially supports asynchronous cancellation.
+Snapshots since then simulate async cancelation by poking the address of
+a cancelation routine into the PC of the threads context. This requires
+the thread to be resumed in some way for the cancelation to actually
+proceed. This is not true async cancelation, but it is as close as we've
+been able to get to it.
+
+If the thread you're trying to cancel is blocked (for instance, it could be
+waiting for data from the network), it will only get cancelled when it unblocks
+(when the data arrives). For true pre-emptive cancelation in these cases,
+pthreads-win32 from snapshot 2004-05-16 can automatically recognise and use the
+QueueUserAPCEx package by Panagiotis E. Hadjidoukas. This package is available
+from the pthreads-win32 ftp site and is included in the pthreads-win32
+self-unpacking zip from 2004-05-16 onwards.
+
+Using deferred cancelation would normally be the way to go, however,
+even though the POSIX threads standard lists a number of C library
+functions that are defined as deferred cancelation points, there is
+no hookup between those which are provided by Windows and the
+pthreads-win32 library.
+
+Incidently, it's worth noting for code portability that the older POSIX
+threads standards cancelation point lists didn't include "select" because
+(as I read in Butenhof) it wasn't part of POSIX. However, it does appear in
+the SUSV3.
+
+Effectively, the only mandatory cancelation points that pthreads-win32
+recognises are those the library implements itself, ie.
+
+ pthread_testcancel
+ pthread_cond_wait
+ pthread_cond_timedwait
+ pthread_join
+ sem_wait
+ sem_timedwait
+ pthread_delay_np
+
+The following routines from the non-mandatory list in SUSV3 are
+cancelation points in pthreads-win32:
+
+ pthread_rwlock_wrlock
+ pthread_rwlock_timedwrlock
+
+The following routines from the non-mandatory list in SUSV3 are not
+cancelation points in pthreads-win32:
+
+ pthread_rwlock_rdlock
+ pthread_rwlock_timedrdlock
+
+Pthreads-win32 also provides two functions that allow you to create
+cancelation points within your application, but only for cases where
+a thread is going to block on a Win32 handle. These are:
+
+ pthreadCancelableWait(HANDLE waitHandle) /* Infinite wait */
+
+ pthreadCancelableTimedWait(HANDLE waitHandle, DWORD timeout)
+

+
+
+Q 10 How do I create thread-safe applications using
+---- pthreadGCE.dll, libpthreadw32.a and Mingw32?
+
+This should not be a problem with recent versions of MinGW32.
+
+For early versions, see Thomas Pfaff's email at:
+http://sources.redhat.com/ml/pthreads-win32/2002/msg00000.html

+# The library can be built with some alternative behaviour to
+# facilitate development of applications on Win32 that will be ported
+# to other POSIX systems. Nothing definable here will make the library
+# non-compliant, but applications that make assumptions that POSIX
+# does not garrantee may fail or misbehave under some settings.
+#
+# PTW32_THREAD_ID_REUSE_INCREMENT
+# Purpose:
+# POSIX says that applications should assume that thread IDs can be
+# recycled. However, Solaris and some other systems use a [very large]
+# sequence number as the thread ID, which provides virtual uniqueness.
+# Pthreads-win32 provides pseudo-unique IDs when the default increment
+# (1) is used, but pthread_t is not a scalar type like Solaris's.
+#
+# Usage:
+# Set to any value in the range: 0 <= value <= 2^wordsize
+#
+# Examples:
+# Set to 0 to emulate non recycle-unique behaviour like Linux or *BSD.
+# Set to 1 for recycle-unique thread IDs (this is the default).
+# Set to some other +ve value to emulate smaller word size types
+# (i.e. will wrap sooner).

+RELEASE 2.8.0
+-------------
+(2006-12-22)
+
+General
+-------
+New bug fixes in this release since 2.7.0 have not been applied to the
+version 1.x.x series. It is probably time to drop version 1.
+
+Testing and verification
+------------------------
+This release has not yet been tested on SMP architechtures. All tests pass
+on a uni-processor system.
+
+Bug fixes
+---------
+Sem_destroy could return EBUSY even though no threads were waiting on the
+semaphore. Other races around invalidating semaphore structs (internally)
+have been removed as well.
+
+New tests
+---------
+semaphore5.c - tests the bug fix referred to above.
+
+
+RELEASE 2.7.0
+-------------
+(2005-06-04)
+
+General
+-------
+All new features in this release have been back-ported in release 1.11.0,
+including the incorporation of MCS locks in pthread_once, however, versions
+1 and 2 remain incompatible even though they are now identical in
+performance and functionality.
+
+Testing and verification
+------------------------
+This release has been tested (passed the test suite) on both uni-processor
+and multi-processor systems.
+- Tim Theisen
+
+Bug fixes
+---------
+Pthread_once has been re-implemented to remove priority boosting and other
+complexity to improve robustness. Races for Win32 handles that are not
+recycle-unique have been removed. The general form of pthread_once is now
+the same as that suggested earlier by Alexander Terekhov, but instead of the
+'named mutex', a queue-based lock has been implemented which has the required
+properties of dynamic self initialisation and destruction. This lock is also
+efficient. The ABI is unaffected in as much as the size of pthread_once_t has
+not changed and PTHREAD_ONCE_INIT has not changed, however, applications that
+peek inside pthread_once_t, which is supposed to be opaque, will break.
+- Vladimir Kliatchko
+
+New features
+------------
+* Support for Mingw cross development tools added to GNUmakefile.
+Mingw cross tools allow building the libraries on Linux.
+- Mikael Magnusson
+
+
+RELEASE 2.6.0
+-------------
+(2005-05-19)
+
+General
+-------
+All of the bug fixes and new features in this release have been
+back-ported in release 1.10.0.
+
+Testing and verification
+------------------------
+This release has been tested (passed the test suite) on both uni-processor
+and multi-processor systems. Thanks to Tim Theisen at TomoTherapy for
+exhaustively running the MP tests and for providing crutial observations
+and data when faults are detected.
+
+Bugs fixed
+----------
+
+* pthread_detach() now reclaims remaining thread resources if called after
+the target thread has terminated. Previously, this routine did nothing in
+this case.
+
+New tests
+---------
+
+* detach1.c - tests that pthread_detach properly invalidates the target
+thread, which indicates that the thread resources have been reclaimed.
+
+
+RELEASE 2.5.0
+-------------
+(2005-05-09)
+
+General
+-------
+
+The package now includes a reference documentation set consisting of
+HTML formatted Unix-style manual pages that have been edited for
+consistency with Pthreads-w32. The set can also be read online at:
+http://sources.redhat.com/pthreads-win32/manual/index.html
+
+Thanks again to Tim Theisen for running the test suite pre-release
+on an MP system.
+
+All of the bug fixes and new features in this release have been
+back-ported in release 1.9.0.
+
+Bugs fixed
+----------
+
+* Thread Specific Data (TSD) key management has been ammended to
+eliminate a source of (what was effectively) resource leakage (a HANDLE
+plus memory for each key destruct routine/thread association). This was
+not a true leak because these resources were eventually reclaimed when
+pthread_key_delete was run AND each thread referencing the key had exited.
+The problem was that these two conditions are often not met until very
+late, and often not until the process is about to exit.
+
+The ammended implementation avoids the need for the problematic HANDLE
+and reclaims the memory as soon as either the key is deleted OR the
+thread exits, whichever is first.
+
+Thanks to Richard Hughes at Aculab for identifying and locating the leak.
+
+* TSD key destructors are now processed up to PTHREAD_DESTRUCTOR_ITERATIONS
+times instead of just once. PTHREAD_DESTRUCTOR_ITERATIONS has been
+defined in pthread.h for some time but not used.
+
+* Fix a semaphore accounting race between sem_post/sem_post_multiple
+and sem_wait cancellation. This is the same issue as with
+sem_timedwait that was fixed in the last release.
+
+* sem_init, sem_post, and sem_post_multiple now check that the
+semaphore count never exceeds _POSIX_SEM_VALUE_MAX.
+
+* Although sigwait() is nothing more than a no-op, it should at least
+be a cancellation point to be consistent with the standard.
+
+New tests
+---------
+
+* stress1.c - attempts to expose problems in condition variable
+and semaphore timed wait logic. This test was inspired by Stephan
+Mueller's sample test code used to identify the sem_timedwait bug
+from the last release. It's not a part of the regular test suite
+because it can take awhile to run. To run it:
+nmake clean VC-stress
+
+* tsd2.c - tests that key destructors are re-run if the tsd key value is
+not NULL after the destructor routine has run. Also tests that
+pthread_setspecific() and pthread_getspecific() are callable from
+destructors.
+
+
+RELEASE 2.4.0
+-------------
+(2005-04-26)
+
+General
+-------
+
+There is now no plan to release a version 3.0.0 to fix problems in
+pthread_once(). Other possible implementations of pthread_once
+will still be investigated for a possible future release in an attempt
+to reduce the current implementation's complexity.
+
+All of the bug fixes and new features in this release have been
+back-ported for release 1.8.0.
+
+Bugs fixed
+----------
+
+* Fixed pthread_once race (failures on an MP system). Thanks to
+Tim Theisen for running exhaustive pre-release testing on his MP system
+using a range of compilers:
+ VC++ 6
+ VC++ 7.1
+ Intel C++ version 8.0
+All tests passed.
+Some minor speed improvements were also done.
+
+* Fix integer overrun error in pthread_mutex_timedlock() - missed when
+sem_timedwait() was fixed in release 2.2.0. This routine no longer returns
+ENOTSUP when NEED_SEM is defined - it is supported (NEED_SEM is only
+required for WinCE versions prior to 3.0).
+
+* Fix timeout bug in sem_timedwait().
+- Thanks to Stephan Mueller for reporting, providing diagnostic output
+and test code.
+
+* Fix several problems in the NEED_SEM conditionally included code.
+NEED_SEM included code is provided for systems that don't implement W32
+semaphores, such as WinCE prior to version 3.0. An alternate implementation
+of POSIX semaphores is built using W32 events for these systems when
+NEED_SEM is defined. This code has been completely rewritten in this
+release to reuse most of the default POSIX semaphore code, and particularly,
+to implement all of the sem_* routines supported by pthreads-win32. Tim
+Theisen also run the test suite over the NEED_SEM code on his MP system. All
+tests passed.
+
+* The library now builds without errors for the Borland Builder 5.5 compiler.
+
+New features
+------------
+
+* pthread_mutex_timedlock() and all sem_* routines provided by
+pthreads-win32 are now implemented for WinCE versions prior to 3.0. Those
+versions did not implement W32 semaphores. Define NEED_SEM in config.h when
+building the library for these systems.
+
+Known issues in this release
+----------------------------
+
+* pthread_once is too complicated - but it works as far as testing can
+determine..
+
+* The Borland version of the dll fails some of the tests with a memory read
+exception. The cause is not yet known but a compiler bug has not been ruled
+out.
+
+
+RELEASE 2.3.0
+-------------
+(2005-04-12)
+
+General
+-------
+
+Release 1.7.0 is a backport of features and bug fixes new in
+this release. See earlier notes under Release 2.0.0/General.
+
+Bugs fixed
+----------
+
+* Fixed pthread_once potential for post once_routine cancellation
+hanging due to starvation. See comments in pthread_once.c.
+Momentary priority boosting is used to ensure that, after a
+once_routine is cancelled, the thread that will run the
+once_routine is not starved by higher priority waiting threads at
+critical times. Priority boosting occurs only AFTER a once_routine
+cancellation, and is applied only to that once_control. The
+once_routine is run at the thread's normal base priority.
+
+New tests
+---------
+
+* once4.c: Aggressively tests pthread_once() under realtime
+conditions using threads with varying priorities. Windows'
+random priority boosting does not occur for threads with realtime
+priority levels.
+
+
+RELEASE 2.2.0
+-------------
+(2005-04-04)
+
+General
+-------
+
+* Added makefile targets to build static link versions of the library.
+Both MinGW and MSVC. Please note that this does not imply any change
+to the LGPL licensing, which still imposes psecific conditions on
+distributing software that has been statically linked with this library.
+
+* There is a known bug in pthread_once(). Cancellation of the init_routine
+exposes a potential starvation (i.e. deadlock) problem if a waiting thread
+has a higher priority than the initting thread. This problem will be fixed
+in version 3.0.0 of the library.
+
+Bugs fixed
+----------
+
+* Fix integer overrun error in sem_timedwait().
+Kevin Lussier
+
+* Fix preprocessor directives for static linking.
+Dimitar Panayotov
+
+
+RELEASE 2.1.0
+-------------
+(2005-03-16)
+
+Bugs fixed
+----------
+
+* Reverse change to pthread_setcancelstate() in 2.0.0.
+
+
+RELEASE 2.0.0
+-------------
+(2005-03-16)
+
+General
+-------
+
+This release represents an ABI change and the DLL version naming has
+incremented from 1 to 2, e.g. pthreadVC2.dll.
+
+Version 1.4.0 back-ports the new functionality included in this
+release. Please distribute DLLs built from that version with updates
+to applications built on pthreads-win32 version 1.x.x.
+
+The package naming has changed, replacing the snapshot date with
+the version number + descriptive information. E.g. this
+release is "pthreads-w32-2-0-0-release".
+
+Bugs fixed
+----------
+
+* pthread_setcancelstate() no longer checks for a pending
+async cancel event if the library is using alertable async
+cancel. See the README file (Prerequisites section) for info
+on adding alertable async cancelation.
+
+New features
+------------
+
+* pthread_once() now supports init_routine cancellability.
+
+New tests
+---------
+
+* Agressively test pthread_once() init_routine cancellability.
+

+Version 1.2.0
+
+Bug fixes
+---------
+
+* Attempted acquisition of a recursive mutex could cause waiting threads
+to not be woken when the mutex was released.
+- Ralf Kubis <RKubis at mc.com>
+

+SNAPSHOT 2005-01-03
+-------------------
+Version 1.1.0
+
+Bug fixes
+---------
+

+unexpectedly return an EPERM error (bug introduced in
+snapshot-2004-11-03).
+- Konstantin Voronkov <beowinkle at yahoo.com>
+
+
+SNAPSHOT 2004-11-22
+-------------------
+Version 1.0.0
+
+This snapshot primarily fixes the condvar bug introduced in
+snapshot-2004-11-03. DLL versioning has also been included to allow
+applications to runtime check the Microsoft compatible DLL version
+information, and to extend the DLL naming system for ABI and major
+(non-backward compatible) API changes. See the README file for details.
+
+Bug fixes
+---------
+
+* Condition variables no longer deadlock (bug introduced in
+snapshot-2004-11-03).
+- Alexander Kotliarov and Nicolas at saintmac
+
+* DLL naming extended to avoid 'DLL hell' in the future, and to
+accommodate the ABI change introduced in snapshot-2004-11-03. Snapshot
+2004-11-03 will be removed from FTP sites.
+
+New features
+------------
+
+* A Microsoft-style version resource has been added to the DLL for
+applications that wish to check DLL compatibility at runtime.
+
+* Pthreads-win32 DLL naming has been extended to allow incompatible DLL
+versions to co-exist in the same filesystem. See the README file for details,
+but briefly: while the version information inside the DLL will change with
+each release from now on, the DLL version names will only change if the new
+DLL is not backward compatible with older applications.
+
+The versioning scheme has been borrowed from GNU Libtool, and the DLL
+naming scheme is from Cygwin. Provided the Libtool-style numbering rules are
+honoured, the Cygwin DLL naming scheme automatcally ensures that DLL name
+changes are minimal and that applications will not load an incompatible
+pthreads-win32 DLL.
+
+Those who use the pre-built DLLs will find that the DLL/LIB names have a new
+suffix (1) in this snapshot. E.g. pthreadVC1.dll etc.
+
+* The POSIX thread ID reuse uniqueness feature introduced in the last snapshot
+has been kept as default, but the behaviour can now be controlled when the DLL
+is built to effectively switch it off. This makes the library much more
+sensitive to applications that assume that POSIX thread IDs are unique, i.e.
+are not strictly compliant with POSIX. See the PTW32_THREAD_ID_REUSE_INCREMENT
+macro comments in config.h for details.
+
+Other changes
+-------------
+Certain POSIX macros have changed.
+
+These changes are intended to conform to the Single Unix Specification version 3,
+which states that, if set to 0 (zero) or not defined, then applications may use
+sysconf() to determine their values at runtime. Pthreads-win32 does not
+implement sysconf().
+
+The following macros are no longer undefined, but defined and set to -1
+(not implemented):
+
+ _POSIX_THREAD_ATTR_STACKADDR
+ _POSIX_THREAD_PRIO_INHERIT
+ _POSIX_THREAD_PRIO_PROTECT
+ _POSIX_THREAD_PROCESS_SHARED
+
+The following macros are defined and set to 200112L (implemented):
+
+ _POSIX_THREADS
+ _POSIX_THREAD_SAFE_FUNCTIONS
+ _POSIX_THREAD_ATTR_STACKSIZE
+ _POSIX_THREAD_PRIORITY_SCHEDULING
+ _POSIX_SEMAPHORES
+ _POSIX_READER_WRITER_LOCKS
+ _POSIX_SPIN_LOCKS
+ _POSIX_BARRIERS
+
+The following macros are defined and set to appropriate values:
+
+ _POSIX_THREAD_THREADS_MAX
+ _POSIX_SEM_VALUE_MAX
+ _POSIX_SEM_NSEMS_MAX
+ PTHREAD_DESTRUCTOR_ITERATIONS
+ PTHREAD_KEYS_MAX
+ PTHREAD_STACK_MIN
+ PTHREAD_THREADS_MAX
+
+
+SNAPSHOT 2004-11-03
+-------------------
+
+DLLs produced from this snapshot cannot be used with older applications without
+recompiling the application, due to a change to pthread_t to provide unique POSIX
+thread IDs.
+
+Although this snapshot passes the extended test suite, many of the changes are
+fairly major, and some applications may show different behaviour than previously,
+so adopt with care. Hopefully, any changed behaviour will be due to the library
+being better at it's job, not worse.
+
+Bug fixes
+---------
+
+* pthread_create() no longer accepts NULL as the thread reference arg.
+A segfault (memory access fault) will result, and no thread will be
+created.
+
+* pthread_barrier_wait() no longer acts as a cancelation point.
+
+* Fix potential race condition in pthread_once()
+- Tristan Savatier <tristan at mpegtv.com>
+
+* Changes to pthread_cond_destroy() exposed some coding weaknesses in several
+test suite mini-apps because pthread_cond_destroy() now returns EBUSY if the CV
+is still in use.
+
+New features
+------------
+
+* Added for compatibility:
+PTHREAD_RECURSIVE_MUTEX_INITIALIZER,
+PTHREAD_ERRORCHECK_MUTEX_INITIALIZER,
+PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP,
+PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP
+
+* Initial support for Digital Mars compiler
+- Anuj Goyal <anuj.goyal at gmail.com>
+
+* Faster Mutexes. These have been been rewritten following a model provided by
+Alexander Terekhov that reduces kernel space checks, and eliminates some additional
+critical sections used to manage a race between timedlock expiration and unlock.
+Please be aware that the new mutexes do not enforce strict absolute FIFO scheduling
+of mutexes, however any out-of-order lock acquisition should be very rare.
+
+* Faster semaphores. Following a similar model to mutexes above, these have been
+rewritten to use preliminary users space checks.
+
+* sem_getvalue() now returns the number of waiters.
+
+* The POSIX thread ID now has much stronger uniqueness characteristics. The library
+garrantees not to reuse the same thread ID for at least 2^(wordsize) thread
+destruction/creation cycles.
+
+New tests
+---------
+
+* semaphore4.c: Tests cancelation of the new sem_wait().
+
+* semaphore4t.c: Likewise for sem_timedwait().
+
+* rwlock8.c: Tests and times the slow execution paths of r/w locks, and the CVs,
+mutexes, and semaphores that they're built on.
+
+
+SNAPSHOT 2004-05-16
+-------------------
+
+Attempt to add Watcom to the list of compilers that can build the library.
+This failed in the end due to it's non-thread-aware errno. The library
+builds but the test suite fails. See README.Watcom for more details.
+
+Bug fixes
+---------
+* Bug and memory leak in sem_init()
+- Alex Blanco <Alex.Blanco at motorola.com>
+
+* ptw32_getprocessors() now returns CPU count of 1 for WinCE.
+- James Ewing <james.ewing at sveasoft.com>
+
+* pthread_cond_wait() could be canceled at a point where it should not
+be cancelable. Fixed.
+- Alexander Terekhov <TEREKHOV at de.ibm.com>
+
+* sem_timedwait() had an incorrect timeout calculation.
+- Philippe Di Cristo <philipped at voicebox.com>
+
+* Fix a memory leak left behind after threads are destroyed.
+- P. van Bruggen <pietvb at newbridges.nl>
+
+New features
+------------
+* Ported to AMD64.
+- Makoto Kato <raven at oldskool.jp>
+
+* True pre-emptive asynchronous cancelation of threads. This is optional
+and requires that Panagiotis E. Hadjidoukas's QueueUserAPCEx package be
+installed. This package is included in the pthreads-win32 self-unpacking
+Zip archive starting from this snapshot. See the README.txt file inside
+the package for installation details.
+
+Note: If you don't use async cancelation in your application, or don't need
+to cancel threads that are blocked on system resources such as network I/O,
+then the default non-preemptive async cancelation is probably good enough.
+However, pthreads-win32 auto-detects the availability of these components
+at run-time, so you don't need to rebuild the library from source if you
+change your mind later.
+
+All of the advice available in books and elsewhere on the undesirability
+of using async cancelation in any application still stands, but this
+feature is a welcome addition with respect to the library's conformance to
+the POSIX standard.
+
+SNAPSHOT 2003-09-18
+-------------------
+
+Cleanup of thread priority management. In particular, setting of thread
+priority now attempts to map invalid Win32 values within the range returned
+by sched_get_priority_min/max() to useful values. See README.NONPORTABLE
+under "Thread priority".
+
+Bug fixes
+---------
+* pthread_getschedparam() now returns the priority given by the most recent
+call to pthread_setschedparam() or established by pthread_create(), as
+required by the standard. Previously, pthread_getschedparam() incorrectly
+returned the running thread priority at the time of the call, which may have
+been adjusted or temporarily promoted/demoted.
+
+* sched_get_priority_min() and sched_get_priority_max() now return -1 on error
+and set errno. Previously, they incorrectly returned the error value directly.
+
+
+SNAPSHOT 2003-09-04
+-------------------
+
+Bug fixes
+---------
+* ptw32_cancelableWait() now allows cancelation of waiting implicit POSIX
+threads.
+
+New test
+--------
+* cancel8.c tests cancelation of Win32 threads waiting at a POSIX cancelation
+point.
+
+
+SNAPSHOT 2003-09-03
+-------------------
+
+Bug fixes
+---------
+* pthread_self() would free the newly created implicit POSIX thread handle if
+DuplicateHandle failed instead of recycle it (very unlikely).
+
+* pthread_exit() was neither freeing nor recycling the POSIX thread struct
+for implicit POSIX threads.
+
+New feature - Cancelation of/by Win32 (non-POSIX) threads
+---------------------------------------------------------
+Since John Bossom's original implementation, the library has allowed non-POSIX
+initialised threads (Win32 threads) to call pthreads-win32 routines and
+therefore interact with POSIX threads. This is done by creating an on-the-fly
+POSIX thread ID for the Win32 thread that, once created, allows fully
+reciprical interaction. This did not extend to thread cancelation (async or
+deferred). Now it does.
+
+Any thread can be canceled by any other thread (Win32 or POSIX) if the former
+thread's POSIX pthread_t value is known. It's TSD destructors and POSIX
+cleanup handlers will be run before the thread exits with an exit code of
+PTHREAD_CANCELED (retrieved with GetExitCodeThread()).
+
+This allows a Win32 thread to, for example, call POSIX CV routines in the same way
+that POSIX threads would/should, with pthread_cond_wait() cancelability and
+cleanup handlers (pthread_cond_wait() is a POSIX cancelation point).
+
+By adding cancelation, Win32 threads should now be able to call all POSIX
+threads routines that make sense including semaphores, mutexes, condition
+variables, read/write locks, barriers, spinlocks, tsd, cleanup push/pop,
+cancelation, pthread_exit, scheduling, etc.
+
+Note that these on-the-fly 'implicit' POSIX thread IDs are initialised as detached
+(not joinable) with deferred cancelation type. The POSIX thread ID will be created
+automatically by any POSIX routines that need a POSIX handle (unless the routine
+needs a pthread_t as a parameter of course). A Win32 thread can discover it's own
+POSIX thread ID by calling pthread_self(), which will create the handle if
+necessary and return the pthread_t value.
+
+New tests
+---------
+Test the above new feature.
+
+
+SNAPSHOT 2003-08-19

+There are no changes to the library source code.
+
+

+- Nicolas Barry <boozai@yahoo.com>
+
+* POSIX thread handles are now reused and their memory is not freed on thread exit.
+This allows for stronger thread validity checking.
+
+New standard routine
+--------------------
+
+* pthread_kill() added to provide thread validity checking to applications.
+It does not accept any non zero values for the signal arg.
+
+New test cases
+--------------
+

+
+
+SNAPSHOT 2003-05-10
+-------------------
+
+Bug fixes
+---------
+
+* pthread_mutex_trylock() now returns correct error values.
+pthread_mutex_destroy() will no longer destroy a recursively locked mutex.
+pthread_mutex_lock() is no longer inadvertantly behaving as a cancelation point.
+- Thomas Pfaff <tpfaff@gmx.net>
+
+* pthread_mutex_timedlock() no longer occasionally sets incorrect mutex
+ownership, causing deadlocks in some applications.
+- Robert Strycek <strycek@posam.sk> and Alexander Terekhov <TEREKHOV@de.ibm.com>
+
+
+SNAPSHOT 2002-11-04
+-------------------
+
+Bug fixes
+---------
+
+* sem_getvalue() now returns the correct value under Win NT and WinCE.
+- Rob Fanner <rfanner@stonethree.com>
+
+* sem_timedwait() now uses tighter checks for unreasonable
+abstime values - that would result in unexpected timeout values.
+
+* ptw32_cond_wait_cleanup() no longer mysteriously consumes
+CV signals but may produce more spurious wakeups. It is believed
+that the sem_timedwait() call is consuming a CV signal that it
+shouldn't.
+- Alexander Terekhov <TEREKHOV@de.ibm.com>
+
+* Fixed a memory leak in ptw32_threadDestroy() for implicit threads.
+
+* Fixed potential for deadlock in pthread_cond_destroy().
+A deadlock could occur for statically declared CVs (PTHREAD_COND_INITIALIZER),
+when one thread is attempting to destroy the condition variable while another
+is attempting to dynamically initialize it.

+
+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.

+ pthreadVSE.lib
+ pthreadVCE.dll (MS VC++/C++ EH)
+ pthreadVCE.lib
+ pthreadGCE.dll (GNU G++/C++ EH)

+
+ Both your application and the pthread dll should use the

+- 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

+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. All rights reserved.
+
+Run one of the following command lines:
+nmake clean VCE (to build the MSVC dll with C++ exception handling)
+nmake clean VSE (to build the MSVC dll with structured exception handling)
+nmake clean VC (to build the MSVC dll with C cleanup code)
+nmake clean VCE-inlined (to build the MSVC inlined dll with C++ exception handling)
+nmake clean VSE-inlined (to build the MSVC inlined dll with structured exception handling)
+nmake clean VC-inlined (to build the MSVC inlined dll with C cleanup code)
+nmake clean VC-static (to build the MSVC static lib with C cleanup code)

+nmake clean VCE-inlined-debug (to build the debug MSVC inlined dll with C++ exception handling)
+nmake clean VSE-inlined-debug (to build the debug MSVC inlined dll with structured exception handling)
+nmake clean VC-inlined-debug (to build the debug MSVC inlined dll with C cleanup code)
+nmake clean VC-static-debug (to build the debug MSVC static lib with C cleanup code)
+
+
+The pre-built dlls are normally built using the *-inlined targets.
+
+You can run the testsuite by changing to the "tests" directory and
+running nmake. E.g.:
+
+$ cd tests
+$ nmake
+
+Microsoft (R) Program Maintenance Utility Version 6.00.8168.0
+Copyright (C) Microsoft Corp 1988-1998. All rights reserved.
+
+Run one of the following command lines:
+nmake clean VC (to test using VC dll with VC (no EH) applications)
+nmake clean VCX (to test using VC dll with VC++ (EH) applications)
+nmake clean VCE (to test using the VCE dll with VC++ EH applications)
+nmake clean VSE (to test using VSE dll with VC (SEH) applications)

+nmake clean VSE-bench (to benchtest using VSE dll with SEH bench app)
+nmake clean VC-static (to test using VC static lib with VC (no EH) applications)
+
+
+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)
+make clean GC-inlined (to build the GNU C inlined dll with C cleanup code)
+make clean GCE-inlined (to build the GNU C inlined dll with C++ exception handling)
+make clean GC-static (to build the GNU C inlined static lib with C cleanup code)
+make clean GC-debug (to build the GNU C debug dll with C cleanup code)
+make clean GCE-debug (to build the GNU C debug dll with C++ exception handling)
+make clean GC-inlined-debug (to build the GNU C inlined debug dll with C cleanup code)
+make clean GCE-inlined-debug (to build the GNU C inlined debug dll with C++ exception handling)
+make clean GC-static-debug (to build the GNU C inlined static debug lib with C cleanup code)
+
+
+The pre-built dlls are normally built using the *-inlined targets.
+
+You can run the testsuite by changing to the "tests" directory and
+running make for help information. E.g.:
+
+$ cd tests
+$ make
+Run one of the following command lines:
+make clean GC (to test using GC dll with C (no EH) applications)
+make clean GCX (to test using GC dll with C++ (EH) applications)
+make clean GCE (to test using GCE dll with C++ (EH) applications)
+make clean GC-bench (to benchtest using GNU C dll with C cleanup code)
+make clean GCE-bench (to benchtest using GNU C dll with C++ exception handling)
+make clean GC-static (to test using GC static lib with C (no EH) applications)
+
+
+Building under Linux using the Mingw32 cross development tools
+--------------------------------------------------------------
+
+You can build the library without leaving Linux by using the Mingw32 cross
+development toolchain. See http://www.libsdl.org/extras/win32/cross/ for
+tools and info. The GNUmakefile contains some support for this, for example:
+
+make CROSS=i386-mingw32msvc- clean GC-inlined
+
+will build pthreadGCn.dll and libpthreadGCn.a (n=version#), provided your
+cross-tools/bin directory is in your PATH (or use the cross-make.sh script
+at the URL above).
+
+
+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 makefiles supplied and used by the following 'make'
+command lines will define this for you.
+
+MSVC (creates pthreadVCn.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. Also, your
+application must call a two non-portable routines to initialise the
+some state on startup and cleanup before exit. One other routine needs
+to be called to cleanup after any Win32 threads have called POSIX API
+routines. See README.NONPORTABLE or the html reference manual pages for
+details on these routines:
+
+BOOL pthread_win32_process_attach_np (void);
+BOOL pthread_win32_process_detach_np (void);
+BOOL pthread_win32_thread_attach_np (void); // Currently a no-op
+BOOL pthread_win32_thread_detach_np (void);
+
+
+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
+ pthreadVC.dll - built with MSVC compiler using C setjmp/longjmp
+ pthreadVC.lib
+ pthreadVCE.dll - built with MSVC++ compiler using C++ EH
+ pthreadVCE.lib
+ pthreadVSE.dll - built with MSVC compiler using SEH
+ pthreadVSE.lib
+ pthreadGC.dll - built with Mingw32 GCC
+ libpthreadGC.a - derived from pthreadGC.dll
+ pthreadGCE.dll - built with Mingw32 G++
+ libpthreadGCE.a - derived from pthreadGCE.dll
+
+As of August 2003 pthreads-win32 pthreadG* versions are built and tested
+using the MinGW + MsysDTK environment current as of that date or later.
+The following file MAY be needed for older MinGW environments.
+
+ gcc.dll - needed to build and run applications that use
+ pthreadGCE.dll.
+
+
+Building applications with GNU compilers
+----------------------------------------
+
+If you're using pthreadGC.dll:
+
+With the three header files, pthreadGC.dll and libpthreadGC.a in the
+same directory as your application myapp.c, you could compile, link
+and run myapp.c under Mingw32 as follows:
+
+ gcc -o myapp.exe myapp.c -I. -L. -lpthreadGC
+ myapp
+
+Or put pthreadGC.dll in an appropriate directory in your PATH,
+put libpthreadGC.a in your system lib directory, and
+put the three header files in your system include directory,
+then use:
+
+ gcc -o myapp.exe myapp.c -lpthreadGC
+ myapp
+
+
+If you're using pthreadGCE.dll:
+
+With the three header files, pthreadGCE.dll, gcc.dll and libpthreadGCE.a
+in the same directory as your application myapp.c, you could compile,
+link and run myapp.c under Mingw32 as follows:
+
+ gcc -x c++ -o myapp.exe myapp.c -I. -L. -lpthreadGCE
+ myapp
+
+Or put pthreadGCE.dll and gcc.dll in an appropriate directory in
+your PATH, put libpthreadGCE.a in your system lib directory, and
+put the three header files in your system include directory,
+then use:
+
+ gcc -x c++ -o myapp.exe myapp.c -lpthreadGCE
+ myapp

+In ptw32_InterlockedCompareExchange.c, I've added a section for
+Borland's compiler; it's identical to that for the MS compiler except
+that it uses /* ... */ comments instead of ; comments.
+
+[RPJ: need to define HAVE_TASM32 in config.h to use the above.]
+
+
+The other file is a makefile suitable for use with Borland's compiler
+(run "make -fBmakefile" in the directory). It builds a single version
+of the library, pthreadBC.dll and the corresponding pthreadBC.lib
+import library, which is comparable to the pthreadVC version; I can't
+personally see any demand for the versions that include structured or
+C++ exception cancellation handling so I haven't attempted to build
+those versions of the library. (I imagine a static version might be
+of use to some, but we can't legally use that on my commercial
+projects so I can't try that out, unfortunately.)
+
+[RPJ: Added tests\Bmakefile as well.]
+
+Borland C++ doesn't define the ENOSYS constant used by pthreads-win32;
+rather than make more extensive patches to the pthreads-win32 source I
+have a mostly-arbitrary constant for it in the makefile. However this
+doesn't make it visible to the application using the library, so if
+anyone actually wants to use this constant in their apps (why?)
+someone might like to make a seperate NEED_BCC_something define to add
+this stuff.
+
+The makefile also #defines EDEADLK as EDEADLOCK, _timeb as timeb, and
+_ftime as ftime, to deal with the minor differences between the two
+RTLs' naming conventions, and sets the compiler flags as required to
+get a normal compile of the library.
+
+[RPJ: Moved errno values and _timeb etc to pthread.h, so apps will also
+use them.]
+
+(While I'm on the subject, the reason Borland users should recompile
+the library, rather than using the impdef/implib technique suggested
+previously on the mailing list, is that a) the errno constants are
+different, so the results returned by the pthread_* functions can be
+meaningless, and b) the errno variable/pseudo-variable itself is
+different in the MS & BCC runtimes, so you can't access the
+pthreadVC's errno from a Borland C++-compiled host application
+correctly - I imagine there are other potential problems from the RTL
+mismatch too.)
+
+[RPJ: Make sure you use the same RTL in both dll and application builds.
+The dll and tests Bmakefiles use cw32mti.lib. Having some trouble with
+memory read exceptions running the test suite using BCC55.]

+README.CV -- Condition Variables
+--------------------------------
+
+The original implementation of condition variables in
+pthreads-win32 was based on a discussion paper:
+
+"Strategies for Implementing POSIX Condition Variables
+on Win32": http://www.cs.wustl.edu/~schmidt/win32-cv-1.html
+
+The changes suggested below were made on Feb 6 2001. This
+file is included in the package for the benefit of anyone
+interested in understanding the pthreads-win32 implementation
+of condition variables and the (sometimes subtle) issues that
+it attempts to resolve.
+
+Thanks go to the individuals whose names appear throughout

+
+ AREA/CLASS/EXAMPLE AFFECTED:
+
+ Implementation of POSIX condition variables - OS.cpp/.h
+
+ DOES THE PROBLEM AFFECT:
+
+ EXECUTION? YES!
+
+ SYNOPSIS:
+
+ a) spurious wakeups (minor problem)
+ b) lost signals
+ c) broadcast deadlock
+ d) unfairness (minor problem)
+
+ DESCRIPTION:
+
+ Please see attached copy of discussion thread
+ from comp.programming.threads for more details on
+ some reported problems. (i've also posted a "fyi"
+ message to ace-users a week or two ago but
+ unfortunately did not get any response so far).
+
+ It seems that current implementation suffers from
+ two essential problems:
+
+ 1) cond.waiters_count does not accurately reflect
+ number of waiters blocked on semaphore - w/o
+ proper synchronisation that could result (in the
+ time window when counter is not accurate)
+ in spurious wakeups organised by subsequent
+ _signals and _broadcasts.
+
+ 2) Always having (with no e.g. copy_and_clear/..)
+ the same queue in use (semaphore+counter)
+ neither signal nor broadcast provide 'atomic'
+ behaviour with respect to other threads/subsequent
+ calls to signal/broadcast/wait.
+
+ Each problem and combination of both could produce
+ various nasty things:
+
+ a) spurious wakeups (minor problem)
+
+ it is possible that waiter(s) which was already
+ unblocked even so is still counted as blocked
+ waiter. signal and broadcast will release
+ semaphore which will produce a spurious wakeup
+ for a 'real' waiter coming later.
+
+ b) lost signals
+
+ signalling thread ends up consuming its own
+ signal. please see demo/discussion below.
+
+ c) broadcast deadlock
+
+ last_waiter processing code does not correctly
+ handle the case with multiple threads
+ waiting for the end of broadcast.
+ please see demo/discussion below.
+
+ d) unfairness (minor problem)
+
+ without SignalObjectAndWait some waiter(s)
+ may end up consuming broadcasted signals
+ multiple times (spurious wakeups) because waiter
+ thread(s) can be preempted before they call
+ semaphore wait (but after count++ and mtx.unlock).
+
+ REPEAT BY:
+
+ See below... run problem demos programs (tennis.cpp and
+ tennisb.cpp) number of times concurrently (on multiprocessor)
+ and in multiple sessions or just add a couple of "Sleep"s
+ as described in the attached copy of discussion thread
+ from comp.programming.threads
+
+ SAMPLE FIX/WORKAROUND:
+
+ See attached patch to pthread-win32.. well, I can not
+ claim that it is completely bug free but at least my
+ test and tests provided by pthreads-win32 seem to work.
+ Perhaps that will help.
+

+
+The implementation you suggested is indeed correct
+one (yes, now I see it :). However it requires from
+signal/broadcast nothing more than to "{ return 0; }"
+That is not the case for pthread-win32 and ACE
+implementations. I do think that these implementations
+(basically the same implementation) have some serious
+problems with wait/signal/broadcast calls. I am looking
+for help to clarify whether these problems are real
+or not. I think that I can demonstrate what I mean
+using one or two small sample programs.

+
+well, you can probably loose your bet.. it was indeed stolen
+by "another" thread but not the one you seem to think of.
+
+I think that what actually happens is the following:
+
+H:\SA\UXX\pt\PTHREADS\TESTS>tennis3.exe
+
+PLAYER-A
+
+PLAYER-B
+
+----PLAYER-B: SPURIOUS WAKEUP!!!
+
+PLAYER-A GONE
+
+PLAYER-B GONE
+
+GAME OVER
+
+H:\SA\UXX\pt\PTHREADS\TESTS>
+
+here you can see that PLAYER-B after playing his first
+ball (which came via signal from PLAYER-A) just dropped
+it down. What happened is that his signal to player A
+was consumed as spurious wakeup by himself (player B).
+
+The implementation has a problem:
+
+================
+waiting threads:
+================
+
+{ /** Critical Section
+
+ inc cond.waiters_count
+
+}
+
+ /*
+ /* Atomic only if using Win32 SignalObjectAndWait
+ /*
+ cond.mtx.release
+
+ /*** ^^-- A THREAD WHICH DID SIGNAL MAY ACQUIRE THE MUTEX,
+ /*** GO INTO WAIT ON THE SAME CONDITION AND OVERTAKE
+ /*** ORIGINAL WAITER(S) CONSUMING ITS OWN SIGNAL!
+
+ cond.sem.wait
+
+Player-A after playing game's initial ball went into
+wait (called _wait) but was pre-empted before reaching
+wait semaphore. He was counted as waiter but was not
+actually waiting/blocked yet.
+
+===============
+signal threads:
+===============
+
+{ /** Critical Section
+
+ waiters_count = cond.waiters_count
+
+}
+
+ if ( waiters_count != 0 )
+
+ sem.post 1
+
+ endif
+
+Player-B after he received signal/ball from Player A
+called _signal. The _signal did see that there was
+one waiter blocked on the condition (Player-A) and
+released the semaphore.. (but it did not unblock
+Player-A because he was not actually blocked).
+Player-B thread continued its execution, called _wait,
+was counted as second waiter BUT was allowed to slip
+through opened semaphore gate (which was opened for
+Player-B) and received his own signal. Player B remained
+blocked followed by Player A. Deadlock happened which
+lasted until main thread came in and said game over.
+
+It seems to me that the implementation fails to
+correctly implement the following statement
+from specification:
+
+http://www.opengroup.org/
+onlinepubs/007908799/xsh/pthread_cond_wait.html
+
+"These functions atomically release mutex and cause
+the calling thread to block on the condition variable
+cond; atomically here means "atomically with respect
+to access by another thread to the mutex and then the
+condition variable". That is, if another thread is
+able to acquire the mutex after the about-to-block
+thread has released it, then a subsequent call to
+pthread_cond_signal() or pthread_cond_broadcast()
+in that thread behaves as if it were issued after
+the about-to-block thread has blocked."
+

+Okay, lets change 'pthread_cond_signal' to 'pthread_cond_broadcast'
+but also add some noise from main() right before declaring the game
+to be over (I need it in order to demonstrate another problem of
+pthread-win32/ACE implementations - broadcast deadlock)...
+.
+.
+.
+It is my understanding of POSIX conditions,
+that on correct implementation added noise
+in form of unnecessary broadcasts from main,
+should not break the tennis program. The
+only 'side effect' of added noise on correct
+implementation would be 'spurious wakeups' of
+players (in fact they are not spurious,
+players just see them as spurious) unblocked,
+not by another player but by main before
+another player had a chance to acquire the
+mutex and change the game state variable:
+.
+.
+.
+
+PLAYER-B
+
+PLAYER-A
+
+---Noise ON...
+
+PLAYER-B
+
+PLAYER-A
+
+.
+.

+
+PLAYER-B
+
+---Stopping the game...
+
+PLAYER-A GONE
+
+PLAYER-B GONE
+
+GAME OVER
+
+H:\SA\UXX\pt\PTHREADS\TESTS>
+

+
+a) cond.waiters_count does not accurately reflect
+number of waiters blocked on semaphore - that could
+result (in the time window when counter is not accurate)
+in spurios wakeups organised by subsequent _signals
+and _broadcasts. From standard compliance point of view
+that is OK but that could be a real problem from
+performance/efficiency point of view.
+
+b) If subsequent broadcast happen to go into wait on
+cond.auto_reset_event_or_sem before previous
+broadcast was unblocked from cond.auto_reset_event_or_sem
+by its last waiter, one of two blocked threads will
+remain blocked because last_waiter processing code
+fails to unblock both threads.
+
+In the situation with tennisb.c the Player-B was put
+in a deadlock by noise (broadcast) coming from main
+thread. And since Player-B holds the game state
+mutex when it calls broadcast, the whole program
+stalled: Player-A was deadlocked on mutex and
+main thread after finishing with producing the noise
+was deadlocked on mutex too (needed to declare the
+game over)

+Subject: win32 conditions: sem+counter+event = broadcast_deadlock +
+ spur.wakeup/unfairness/incorrectness ??
+
+
+
+
+
+
+
+Hi,
+
+Problem 1: broadcast_deadlock
+
+It seems that current implementation does not provide "atomic"
+broadcasts. That may lead to "nested" broadcasts... and it seems
+that nested case is not handled correctly -> producing a broadcast
+DEADLOCK as a result.
+
+Scenario:
+
+N (>1) waiting threads W1..N are blocked (in _wait) on condition's
+semaphore.
+
+Thread B1 calls pthread_cond_broadcast, which results in "releasing" N
+W threads via incrementing semaphore counter by N (stored in
+cv->waiters) BUT cv->waiters counter does not change!! The caller
+thread B1 remains blocked on cv->waitersDone event (auto-reset!!) BUT
+condition is not protected from starting another broadcast (when called
+on another thread) while still waiting for the "old" broadcast to
+complete on thread B1.
+
+M (>=0, <N) W threads are fast enough to go thru their _wait call and
+decrement cv->waiters counter.
+
+L (N-M) "late" waiter W threads are a) still blocked/not returned from
+their semaphore wait call or b) were preempted after sem_wait but before
+lock( &cv->waitersLock ) or c) are blocked on cv->waitersLock.
+
+cv->waiters is still > 0 (= L).
+
+Another thread B2 (or some W thread from M group) calls
+pthread_cond_broadcast and gains access to counter... neither a) nor b)
+prevent thread B2 in pthread_cond_broadcast from gaining access to
+counter and starting another broadcast ( for c) - it depends on
+cv->waitersLock scheduling rules: FIFO=OK, PRTY=PROBLEM,... )
+
+That call to pthread_cond_broadcast (on thread B2) will result in
+incrementing semaphore by cv->waiters (=L) which is INCORRECT (all
+W1..N were in fact already released by thread B1) and waiting on
+_auto-reset_ event cv->waitersDone which is DEADLY WRONG (produces a
+deadlock)...
+
+All late W1..L threads now have a chance to complete their _wait call.
+Last W_L thread sets an auto-reselt event cv->waitersDone which will
+release either B1 or B2 leaving one of B threads in a deadlock.
+
+Problem 2: spur.wakeup/unfairness/incorrectness
+
+It seems that:
+
+a) because of the same problem with counter which does not reflect the
+actual number of NOT RELEASED waiters, the signal call may increment
+a semaphore counter w/o having a waiter blocked on it. That will result
+in (best case) spurious wake ups - performance degradation due to
+unnecessary context switches and predicate re-checks and (in worth case)
+unfairness/incorrectness problem - see b)
+
+b) neither signal nor broadcast prevent other threads - "new waiters"
+(and in the case of signal, the caller thread as well) from going into
+_wait and overtaking "old" waiters (already released but still not returned
+from sem_wait on condition's semaphore). Win semaphore just [API DOC]:
+"Maintains a count between zero and some maximum value, limiting the number
+of threads that are simultaneously accessing a shared resource." Calling
+ReleaseSemaphore does not imply (at least not documented) that on return
+from ReleaseSemaphore all waiters will in fact become released (returned
+from their Wait... call) and/or that new waiters calling Wait... afterwards
+will become less importance. It is NOT documented to be an atomic release
+of
+waiters... And even if it would be there is still a problem with a thread
+being preempted after Wait on semaphore and before Wait on cv->waitersLock
+and scheduling rules for cv->waitersLock itself
+(??WaitForMultipleObjects??)
+That may result in unfairness/incorrectness problem as described
+for SetEvent impl. in "Strategies for Implementing POSIX Condition
+Variables
+on Win32": http://www.cs.wustl.edu/~schmidt/win32-cv-1.html
+
+Unfairness -- The semantics of the POSIX pthread_cond_broadcast function is
+to wake up all threads currently blocked in wait calls on the condition
+variable. The awakened threads then compete for the external_mutex. To
+ensure
+fairness, all of these threads should be released from their
+pthread_cond_wait calls and allowed to recheck their condition expressions
+before other threads can successfully complete a wait on the condition
+variable.
+
+Unfortunately, the SetEvent implementation above does not guarantee that
+all
+threads sleeping on the condition variable when cond_broadcast is called
+will
+acquire the external_mutex and check their condition expressions. Although
+the Pthreads specification does not mandate this degree of fairness, the
+lack of fairness can cause starvation.
+
+To illustrate the unfairness problem, imagine there are 2 threads, C1 and
+C2,
+that are blocked in pthread_cond_wait on condition variable not_empty_ that
+is guarding a thread-safe message queue. Another thread, P1 then places two
+messages onto the queue and calls pthread_cond_broadcast. If C1 returns
+from
+pthread_cond_wait, dequeues and processes the message, and immediately
+waits
+again then it and only it may end up acquiring both messages. Thus, C2 will
+never get a chance to dequeue a message and run.
+
+The following illustrates the sequence of events:
+
+1. Thread C1 attempts to dequeue and waits on CV non_empty_
+2. Thread C2 attempts to dequeue and waits on CV non_empty_
+3. Thread P1 enqueues 2 messages and broadcasts to CV not_empty_
+4. Thread P1 exits
+5. Thread C1 wakes up from CV not_empty_, dequeues a message and runs
+6. Thread C1 waits again on CV not_empty_, immediately dequeues the 2nd
+ message and runs
+7. Thread C1 exits
+8. Thread C2 is the only thread left and blocks forever since
+ not_empty_ will never be signaled
+
+Depending on the algorithm being implemented, this lack of fairness may
+yield
+concurrent programs that have subtle bugs. Of course, application
+developers
+should not rely on the fairness semantics of pthread_cond_broadcast.
+However,
+there are many cases where fair implementations of condition variables can
+simplify application code.
+
+Incorrectness -- A variation on the unfairness problem described above
+occurs
+when a third consumer thread, C3, is allowed to slip through even though it
+was not waiting on condition variable not_empty_ when a broadcast occurred.
+
+To illustrate this, we will use the same scenario as above: 2 threads, C1
+and
+C2, are blocked dequeuing messages from the message queue. Another thread,
+P1
+then places two messages onto the queue and calls pthread_cond_broadcast.
+C1
+returns from pthread_cond_wait, dequeues and processes the message. At this
+time, C3 acquires the external_mutex, calls pthread_cond_wait and waits on
+the events in WaitForMultipleObjects. Since C2 has not had a chance to run
+yet, the BROADCAST event is still signaled. C3 then returns from
+WaitForMultipleObjects, and dequeues and processes the message in the
+queue.
+Thus, C2 will never get a chance to dequeue a message and run.
+
+The following illustrates the sequence of events:
+
+1. Thread C1 attempts to dequeue and waits on CV non_empty_
+2. Thread C2 attempts to dequeue and waits on CV non_empty_
+3. Thread P1 enqueues 2 messages and broadcasts to CV not_empty_
+4. Thread P1 exits
+5. Thread C1 wakes up from CV not_empty_, dequeues a message and runs
+6. Thread C1 exits
+7. Thread C3 waits on CV not_empty_, immediately dequeues the 2nd
+ message and runs
+8. Thread C3 exits
+9. Thread C2 is the only thread left and blocks forever since
+ not_empty_ will never be signaled
+
+In the above case, a thread that was not waiting on the condition variable
+when a broadcast occurred was allowed to proceed. This leads to incorrect
+semantics for a condition variable.

+
+I'm not sure how we are any more fair about this than Linux. We certainly
+don't guarantee that the threads released by the first broadcast will get
+the external mutex before the threads of the second wave. In fact, it is
+possible that those threads will never get the external mutex if there is
+enough contention for it.
+
+> e.g. i was thinking about implementation with a pool of
+> N semaphores/counters [...]
+
+I considered that too. The problem is as you mentioned in a). You really
+need to assign threads to semaphores once you know how you want to wake them
+up, not when they first begin waiting which is the only time you can assign
+them.
+
+> well, i am not quite sure that i've fully understood your scenario,
+
+Hmm. Well, it think it's an important example, so I'll try again. First, we
+have thread A which we KNOW is waiting on a condition. As soon as it becomes
+unblocked for any reason, we will know because it will set a flag. Since the
+flag is not set, we are 100% confident that thread A is waiting on the
+condition. We have another thread, thread B, which has acquired the mutex
+and is about to wait on the condition. Thus it is pretty clear that at any
+point, either just A is waiting, or A and B are waiting. Now thread C comes
+along. C is about to do a broadcast on the condition. A broadcast is
+guaranteed to unblock all threads currently waiting on a condition, right?
+Again, we said that either just A is waiting, or A and B are both waiting.
+So, when C does its broadcast, depending upon whether B has started waiting
+or not, thread C will unblock A or unblock A and B. Either way, C must
+unblock A, right?
+
+Now, you said anything that happens is correct so long as a) "a signal is
+not lost between unlocking the mutex and waiting on the condition" and b) "a
+thread must not steal a signal it sent", correct? Requirement b) is easy to
+satisfy: in this scenario, thread C will never wait on the condition, so it
+won't steal any signals. Requirement a) is not hard either. The only way we
+could fail to meet requirement a) in this scenario is if thread B was
+started waiting but didn't wake up because a signal was lost. This will not
+happen.
+
+Now, here is what happens. Assume thread C beats thread B. Thread C looks to
+see how many threads are waiting on the condition. Thread C sees just one
+thread, thread A, waiting. It does a broadcast waking up just one thread
+because just one thread is waiting. Next, before A can become unblocked,
+thread B begins waiting. Now there are two threads waiting, but only one
+will be unblocked. Suppose B wins. B will become unblocked. A will not
+become unblocked, because C only unblocked one thread (sema_post cond, 1).
+So at the end, B finishes and A remains blocked.
+
+We have met both of your requirements, so by your rules, this is an
+acceptable outcome. However, I think that the spec says this is an
+unacceptable outcome! We know for certain that A was waiting and that C did
+a broadcast, but A did not become unblocked! Yet, the spec says that a
+broadcast wakes up all waiting threads. This did not happen. Do you agree
+that this shows your rules are not strict enough?
+
+> and what about N2? :) this one does allow almost everything.
+
+Don't get me started about rule #2. I'll NEVER advocate an algorithm that
+uses rule 2 as an excuse to suck!
+

+
+You are correct. My mistake.
+
+> i would remove "_bTimedOut=false".. after all, it was a real timeout..
+
+I disagree. A thread that can't successfully retract its waiter status can't
+really have timed out. If a thread can't return without executing extra code
+to deal with the fact that someone tried to unblock it, I think it is a poor
+idea to pretend we
+didn't realize someone was trying to signal us. After all, a signal is more
+important than a time out.
+
+> when nSignaled != 0, it is possible to update nWaiters (--) and do not

+
+I realize this, but I was thinking that writing it the other ways saves
+another if statement.
+
+> adjust only if nGone != 0 and save one cache memory write - probably much
+slower than 'if'
+
+Hmm. You are probably right.
+

+
+Also true. Not only that, but you also have the possibility that one could
+overflow the number of waiters as well! However, considering the limit you
+have chosen for nWaitersGone, I suppose it is unlikely that anyone would be
+able to get INT_MAX/2 threads waiting on a single condition. :)
+
+Analysis of 8a:
+
+It looks correct to me.
+
+What are IPC semaphores?
+
+In the line where you state, "else if ( nWaitersBlocked > nWaitersGone ) {
+// HARMLESS RACE CONDITION!" there is no race condition for nWaitersGone
+because nWaitersGone is never modified without holding mtxUnblockLock. You
+are correct that there is a harmless race on nWaitersBlocked, which can
+increase and make the condition become true just after we check it. If this
+happens, we interpret it as the wait starting after the signal.
+
+I like your optimization of this. You could improve Alg. 6 as follows:
+---------- Algorithm 6b ----------
+signal(bAll) {
+ _nSig=0
+ lock counters
+ // this is safe because nWaiting can only be decremented by a thread that
+ // owns counters and nGone can only be changed by a thread that owns
+counters.
+ if (nWaiting>nGone) {
+ if (0==nSignaled) {
+ sema_wait gate // close gate if not already closed
+ }
+ if (nGone>0) {
+ nWaiting-=nGone
+ nGone=0
+ }
+ _nSig=bAll?nWaiting:1
+ nSignaled+=_nSig
+ nWaiting-=_nSig
+ }
+ unlock counters
+ if (0!=_nSig) {
+ sema_post queue, _nSig
+ }
+}
+---------- ---------- ----------
+I guess this wouldn't apply to Alg 8a because nWaitersGone changes meanings
+depending upon whether the gate is open or closed.
+
+In the loop "while ( nWaitersWasGone-- ) {" you do a sema_wait on
+semBlockLock. Perhaps waiting on semBlockQueue would be a better idea.
+
+What have you gained by making the last thread to be signaled do the waits
+for all the timed out threads, besides added complexity? It took me a long
+time to figure out what your objective was with this, to realize you were
+using nWaitersGone to mean two different things, and to verify that you
+hadn't introduced any bug by doing this. Even now I'm not 100% sure.
+
+What has all this playing about with nWaitersGone really gained us besides a
+lot of complexity (it is much harder to verify that this solution is
+correct), execution overhead (we now have a lot more if statements to
+evaluate), and space overhead (more space for the extra code, and another
+integer in our data)? We did manage to save a lock/unlock pair in an
+uncommon case (when a time out occurs) at the above mentioned expenses in
+the common cases.
+
+As for 8b, c, and d, they look ok though I haven't studied them thoroughly.
+What would you use them for?

+barrier it establishes between two races (1st and 2nd wave waiters) for
+the mutex which under 'normal' circumstances (e.g. all threads of equal
+priorities,..) will 'probably' result in fair behaviour with respect to
+mutex ownership.
+
+>> well, i am not quite sure that i've fully understood your scenario,
+>
+>Hmm. Well, it think it's an important example, so I'll try again. ...
+
+ok. now i seem to understand this example. well, now it seems to me
+that the only meaningful rule is just:
+
+a) "a signal is not lost between unlocking the mutex and waiting on the
+condition"
+
+and that the rule
+
+b) "a thread must not steal a signal it sent"
+
+is not needed at all because a thread which violates b) also violates a).
+
+i'll try to explain..
+
+i think that the most important thing is how POSIX defines waiter's
+visibility:
+
+"if another thread is able to acquire the mutex after the about-to-block
+thread
+has released it, then a subsequent call to pthread_cond_signal() or
+pthread_cond_broadcast() in that thread behaves as if it were issued after
+the about-to-block thread has blocked. "
+
+my understanding is the following:
+
+1) there is no guarantees whatsoever with respect to whether
+signal/broadcast
+will actually unblock any 'waiter' if it is done w/o acquiring the mutex
+first
+(note that a thread may release it before signal/broadcast - it does not
+matter).
+
+2) it is guaranteed that waiters become 'visible' - eligible for unblock as
+soon
+as signalling thread acquires the mutex (but not before!!)
+
+so..
+
+>So, when C does its broadcast, depending upon whether B has started
+waiting
+>or not, thread C will unblock A or unblock A and B. Either way, C must
+>unblock A, right?
+
+right. but only if C did acquire the mutex prior to broadcast (it may
+release it before broadcast as well).
+
+implementation will violate waiters visibility rule (signal will become
+lost)
+if C will not unblock A.
+
+>Now, here is what happens. Assume thread C beats thread B. Thread C looks
+to
+>see how many threads are waiting on the condition. Thread C sees just one

+>So at the end, B finishes and A remains blocked.
+
+thread C did acquire the mutex ("Thread C sees just one thread, thread A,
+waiting"). beginning from that moment it is guaranteed that subsequent
+broadcast will unblock A. Otherwise we will have a lost signal with respect
+to A. I do think that it does not matter whether the signal was physically
+(completely) lost or was just stolen by another thread (B) - in both cases
+it was simply lost with respect to A.
+
+>..Do you agree that this shows your rules are not strict enough?
+
+probably the opposite.. :-) i think that it shows that the only meaningful
+rule is
+
+a) "a signal is not lost between unlocking the mutex and waiting on the
+condition"
+
+with clarification of waiters visibility as defined by POSIX above.
+
+>> i would remove "_bTimedOut=false".. after all, it was a real timeout..

+
+a) POSIX does allow timed out thread to consume a signal (cancelled is
+not).
+b) ETIMEDOUT status just says that: "The time specified by abstime to
+pthread_cond_timedwait() has passed."
+c) it seem to me that hiding timeouts would violate "The
+pthread_cond_timedwait()
+function is the same as pthread_cond_wait() except that an error is
+returned if
+the absolute time specified by abstime passes (that is, system time equals
+or
+exceeds abstime) before the condition cond is signaled or broadcasted"
+because
+the abs. time did really pass before cond was signaled (waiter was
+released via semaphore). however, if it really matters, i could imaging
+that we
+can save an abs. time of signal/broadcast and compare it with timeout after
+unblock to find out whether it was a 'real' timeout or not. absent this
+check
+i do think that hiding timeouts would result in technical violation of
+specification.. but i think that this check is not important and we can
+simply
+trust timeout error code provided by wait since we are not trying to make
+'hard' realtime implementation.

+
+well, the reason why i've asked on comp.programming.threads whether this
+race
+condition is harmless or not is that in order to be harmless it should not
+violate the waiters visibility rule (see above). Fortunately, we increment
+the counter under protection of external mutex.. so that any (signalling)

+(in signal) according to POSIX memory visibility rules and mutexes
+(memory barriers). But i am not so sure how it actually works on

+
+well, please consider the following:
+
+1) with multiple waiters unblocked (but some timed out) the trick with
+counter
+seem to ensure potentially higher level of concurrency by not delaying
+most of unblocked waiters for semaphore cleanup - only the last one
+will be delayed but all others would already contend/acquire/release
+the external mutex - the critical section protected by mtxUnblockLock is
+made smaller (increment + couple of IFs is faster than system/kernel call)
+which i think is good in general. however, you are right, this is done
+at expense of 'normal' waiters..
+
+2) some semaphore APIs (e.g. POSIX IPC sems) do allow to adjust the
+semaphore counter in one call => less system/kernel calls.. imagine:
+
+if ( 1 == nSignalsWasLeft ) {
+ if ( 0 != nWaitersWasGone ) {
+ ReleaseSemaphore( semBlockQueue,-nWaitersWasGone ); // better now
+than spurious later
+ }
+ sem_post( semBlockLock ); // open the gate
+ }
+
+3) even on win32 a single thread doing multiple cleanup calls (to wait)
+will probably result in faster execution (because of processor caching)
+than multiple threads each doing a single call to wait.
+
+>As for 8b, c, and d, they look ok though I haven't studied them
+thoroughly.
+>What would you use them for?
+
+8b) for semaphores which do not allow to unblock multiple waiters
+in a single call to post/release (e.g. POSIX realtime semaphores -
+<semaphore.h>)
+
+8c/8d) for WinCE prior to 3.0 (WinCE 3.0 does have semaphores)
+
+ok. so, which one is the 'final' algorithm(s) which we should use in
+pthreads-win32??
+
+regards,
+alexander.

+up, not when they first begin waiting which is the only time you can assign
+them.
+
+> well, i am not quite sure that i've fully understood your scenario,
+
+Hmm. Well, it think it's an important example, so I'll try again. First, we
+have thread A which we KNOW is waiting on a condition. As soon as it
+becomes
+unblocked for any reason, we will know because it will set a flag. Since
+the
+flag is not set, we are 100% confident that thread A is waiting on the
+condition. We have another thread, thread B, which has acquired the mutex
+and is about to wait on the condition. Thus it is pretty clear that at any
+point, either just A is waiting, or A and B are waiting. Now thread C comes
+along. C is about to do a broadcast on the condition. A broadcast is
+guaranteed to unblock all threads currently waiting on a condition, right?
+Again, we said that either just A is waiting, or A and B are both waiting.
+So, when C does its broadcast, depending upon whether B has started waiting
+or not, thread C will unblock A or unblock A and B. Either way, C must
+unblock A, right?
+
+Now, you said anything that happens is correct so long as a) "a signal is
+not lost between unlocking the mutex and waiting on the condition" and b)
+"a
+thread must not steal a signal it sent", correct? Requirement b) is easy to
+satisfy: in this scenario, thread C will never wait on the condition, so it
+won't steal any signals. Requirement a) is not hard either. The only way
+we
+could fail to meet requirement a) in this scenario is if thread B was
+started waiting but didn't wake up because a signal was lost. This will not
+happen.
+
+Now, here is what happens. Assume thread C beats thread B. Thread C looks
+to
+see how many threads are waiting on the condition. Thread C sees just one
+thread, thread A, waiting. It does a broadcast waking up just one thread
+because just one thread is waiting. Next, before A can become unblocked,
+thread B begins waiting. Now there are two threads waiting, but only one
+will be unblocked. Suppose B wins. B will become unblocked. A will not
+become unblocked, because C only unblocked one thread (sema_post cond, 1).
+So at the end, B finishes and A remains blocked.
+
+We have met both of your requirements, so by your rules, this is an
+acceptable outcome. However, I think that the spec says this is an
+unacceptable outcome! We know for certain that A was waiting and that C did
+a broadcast, but A did not become unblocked! Yet, the spec says that a
+broadcast wakes up all waiting threads. This did not happen. Do you agree
+that this shows your rules are not strict enough?
+
+> and what about N2? :) this one does allow almost everything.
+
+Don't get me started about rule #2. I'll NEVER advocate an algorithm that
+uses rule 2 as an excuse to suck!
+

+> of a race condition.
+
+You are correct. My mistake.
+
+> i would remove "_bTimedOut=false".. after all, it was a real timeout..
+
+I disagree. A thread that can't successfully retract its waiter status
+can't
+really have timed out. If a thread can't return without executing extra
+code
+to deal with the fact that someone tried to unblock it, I think it is a
+poor
+idea to pretend we
+didn't realize someone was trying to signal us. After all, a signal is more
+important than a time out.
+
+> when nSignaled != 0, it is possible to update nWaiters (--) and do not
+> touch nGone
+
+I realize this, but I was thinking that writing it the other ways saves
+another if statement.
+
+> adjust only if nGone != 0 and save one cache memory write - probably much
+slower than 'if'
+
+Hmm. You are probably right.
+
+> well, in a strange (e.g. timeout test) program you may (theoretically)
+> have an overflow of nWaiters/nGone counters (with waiters repeatedly
+timing
+> out and no signals at all).
+
+Also true. Not only that, but you also have the possibility that one could
+overflow the number of waiters as well! However, considering the limit you
+have chosen for nWaitersGone, I suppose it is unlikely that anyone would be
+able to get INT_MAX/2 threads waiting on a single condition. :)
+
+Analysis of 8a:
+
+It looks correct to me.
+
+What are IPC semaphores?
+
+In the line where you state, "else if ( nWaitersBlocked > nWaitersGone ) {
+// HARMLESS RACE CONDITION!" there is no race condition for nWaitersGone
+because nWaitersGone is never modified without holding mtxUnblockLock. You
+are correct that there is a harmless race on nWaitersBlocked, which can
+increase and make the condition become true just after we check it. If this
+happens, we interpret it as the wait starting after the signal.
+
+I like your optimization of this. You could improve Alg. 6 as follows:
+---------- Algorithm 6b ----------
+signal(bAll) {
+ _nSig=0
+ lock counters
+ // this is safe because nWaiting can only be decremented by a thread that
+ // owns counters and nGone can only be changed by a thread that owns
+counters.
+ if (nWaiting>nGone) {
+ if (0==nSignaled) {
+ sema_wait gate // close gate if not already closed
+ }
+ if (nGone>0) {
+ nWaiting-=nGone
+ nGone=0
+ }
+ _nSig=bAll?nWaiting:1
+ nSignaled+=_nSig
+ nWaiting-=_nSig
+ }
+ unlock counters
+ if (0!=_nSig) {
+ sema_post queue, _nSig
+ }
+}
+---------- ---------- ----------
+I guess this wouldn't apply to Alg 8a because nWaitersGone changes meanings
+depending upon whether the gate is open or closed.
+
+In the loop "while ( nWaitersWasGone-- ) {" you do a sema_wait on
+semBlockLock. Perhaps waiting on semBlockQueue would be a better idea.
+
+What have you gained by making the last thread to be signaled do the waits
+for all the timed out threads, besides added complexity? It took me a long
+time to figure out what your objective was with this, to realize you were
+using nWaitersGone to mean two different things, and to verify that you
+hadn't introduced any bug by doing this. Even now I'm not 100% sure.
+
+What has all this playing about with nWaitersGone really gained us besides
+a
+lot of complexity (it is much harder to verify that this solution is
+correct), execution overhead (we now have a lot more if statements to
+evaluate), and space overhead (more space for the extra code, and another
+integer in our data)? We did manage to save a lock/unlock pair in an
+uncommon case (when a time out occurs) at the above mentioned expenses in
+the common cases.
+
+As for 8b, c, and d, they look ok though I haven't studied them thoroughly.
+What would you use them for?
+
+ Later,
+ -Louis! :)

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

+ 29 REALTIME_PRIORITY_CLASS 5
+ 30 REALTIME_PRIORITY_CLASS 6
+ 31 REALTIME_PRIORITY_CLASS THREAD_PRIORITY_TIME_CRITICAL
+
+ Windows NT: Values -7, -6, -5, -4, -3, 3, 4, 5, and 6 are not supported.
+
+
+ As you can see, the real priority levels available to any individual
+ Win32 thread are non-contiguous.
+
+ An application using pthreads-win32 should not make assumptions about
+ the numbers used to represent thread priority levels, except that they
+ are monotonic between the values returned by sched_get_priority_min()
+ and sched_get_priority_max(). E.g. Windows 95, 98, NT, 2000, XP make
+ available a non-contiguous range of numbers between -15 and 15, while
+ at least one version of WinCE (3.0) defines the minimum priority
+ (THREAD_PRIORITY_LOWEST) as 5, and the maximum priority
+ (THREAD_PRIORITY_HIGHEST) as 1.
+
+ Internally, pthreads-win32 maps any priority levels between
+ THREAD_PRIORITY_IDLE and THREAD_PRIORITY_LOWEST to THREAD_PRIORITY_LOWEST,
+ or between THREAD_PRIORITY_TIME_CRITICAL and THREAD_PRIORITY_HIGHEST to
+ THREAD_PRIORITY_HIGHEST. Currently, this also applies to
+ REALTIME_PRIORITY_CLASSi even if levels -7, -6, -5, -4, -3, 3, 4, 5, and 6
+ are supported.
+
+ If it wishes, a Win32 application using pthreads-win32 can use the Win32
+ defined priority macros THREAD_PRIORITY_IDLE through
+ THREAD_PRIORITY_TIME_CRITICAL.

+
+
+Current known problems
+----------------------
+
+Library build:
+The Watcom compiler uses a different default call convention to MS C or GNU C and so
+applications are not compatible with pthreadVC.dll etc using pre 2003-10-14 versions
+of pthread.h, sched.h, or semaphore.h. The cdecl attribute can be used on exposed
+function prototypes to force compatibility with MS C built DLLs.
+
+However, there appear to be other incompatibilities. Errno.h, for example, defines
+different values for the standard C and POSIX errors to those defined by the MS C
+errno.h. It may be that references to Watcom's threads compatible 'errno' do set
+and return translated numbers consistently, but I have not verified this.
+
+Watcom defines errno as a dereferenced pointer returned by the function
+_get_errno_ptr(). This is similar to both the MS and GNU C environments for
+multithreaded use. However, the Watcom version appears to have a number of problems:
+
+- different threads return the same pointer value. Compare with the MS and GNU C
+versions which correctly return different values (since each thread must maintain
+a thread specific errno value).
+
+- an errno value set within the DLL appears as zero in the application even though
+both share the same thread.
+
+Therefore applications built using the Watcom compiler may need to use
+a Watcom built version of the library (pthreadWC.dll). If this is the case, then
+the cdecl function attribute should not be required.
+
+Application builds:
+The test suite fails with the Watcom compiler.
+
+Test semaphore1.c fails for pthreadWC.dll because errno returns 0 instead of EAGAIN.

+NOTE: The comments in this file relate to the original WinCE port
+done by Tristan Savatier. The semaphore routines have been
+completely rewritten since (2005-04-25), having been progressively
+broken more and more by changes to the library. All of the semaphore
+routines implemented for W9x/WNT/2000 and up should now also work for
+WinCE. Also, pthread_mutex_timedlock should now work. [RPJ]
+
+----
+
+Some interesting news:
+
+I have been able to port pthread-win32 to Windows-CE,
+which uses a subset of the WIN32 API.
+
+Since we intend to keep using pthread-win32 for our
+Commercial WinCE developments, I would be very interested
+if WinCE support could be added to the main source tree
+of pthread-win32. Also, I would like to be credited
+for this port :-)
+
+Now, here is the story...
+
+The port was performed and tested on a Casio "Cassiopeia"
+PalmSize PC, which runs a MIP processor. The OS in the
+Casio is WinCE version 2.11, but I used VC++ 6.0 with
+the WinCE SDK for version 2.01.
+
+I used pthread-win32 to port a heavily multithreaded
+commercial application (real-time MPEG video player)
+from Linux to WinCE. I consider the changes that
+I have done to be quite well tested.
+
+Overall the modifications that we had to do are minor.
+
+The WinCE port were based on pthread-win32-snap-1999-05-30,
+but I am certain that they can be integrated very easiely
+to more recent versions of the source.
+
+I have attached the modified source code:
+pthread-win32-snap-1999-05-30-WinCE.
+
+All the changes do not affect the code compiled on non-WinCE
+environment, provided that the macros used for WinCE compilation
+are not used, of course!
+
+Overall description of the WinCE port:
+-------------------------------------
+
+Most of the changes had to be made in areas where
+pthread-win32 was relying on some standard-C librairies
+(e.g. _ftime, calloc, errno), which are not available
+on WinCE. We have changed the code to use native Win32
+API instead (or in some cases we made wrappers).
+
+The Win32 Semaphores are not available,
+so we had to re-implement Semaphores using mutexes
+and events.
+
+Limitations / known problems of the WinCE port:
+----------------------------------------------
+
+Not all the semaphore routines have been ported
+(semaphores are defined by Posix but are not part
+pf pthread). I have just done enough to make
+pthread routines (that rely internally on semaphores)
+work, like signal conditions.
+
+I noticed that the Win32 threads work slightly
+differently on WinCE. This may have some impact
+on some tricky parts of pthread-win32, but I have
+not really investigated. For example, on WinCE,
+the process is killed if the main thread falls off
+the bottom (or calls pthread_exit), regardless
+of the existence of any other detached thread.
+Microsoft manual indicates that this behavior is
+deffirent from that of Windows Threads for other
+Win32 platforms.
+
+
+Detailed descriptions of the changes and rationals:
+
+------------------------------------
+- use a new macro NEED_ERRNO.
+
+If defined, the code in errno.c that defines a reentrant errno
+is compiled, regardless of _MT and _REENTRANT.
+
+Rational: On WinCE, there is no support for <stdio.h>, <errno.h> or
+any other standard C library, i.e. even if _MT or _REENTRANT
+is defined, errno is not provided by any library. NEED_ERRNO
+must be set to compile for WinCE.
+
+------------------------------------
+- In implement.h, change #include <semaphore.h> to #include "semaphore.h".
+
+Rational: semaphore.h is provided in pthread-win32 and should not
+be searched in the systems standard include. would not compile.
+This change does not seem to create problems on "classic" win32
+(e.g. win95).
+
+------------------------------------
+- use a new macro NEED_CALLOC.
+
+If defined, some code in misc.c will provide a replacement
+for calloc, which is not available on Win32.
+
+
+------------------------------------
+- use a new macro NEED_CREATETHREAD.
+
+If defined, implement.h defines the macro _beginthreadex
+and _endthreadex.
+
+Rational: On WinCE, the wrappers _beginthreadex and _endthreadex
+do not exist. The native Win32 routines must be used.
+
+------------------------------------
+- in misc.c:
+
+#ifdef NEED_DUPLICATEHANDLE
+ /* DuplicateHandle does not exist on WinCE */
+ self->threadH = GetCurrentThread();
+#else
+ if( !DuplicateHandle(
+ GetCurrentProcess(),
+ GetCurrentThread(),
+ GetCurrentProcess(),
+ &self->threadH,
+ 0,
+ FALSE,
+ DUPLICATE_SAME_ACCESS ) )
+ {
+ free( self );
+ return (NULL);
+ }
+#endif
+
+Rational: On WinCE, DuplicateHandle does not exist. I could not understand
+why DuplicateHandle must be used. It seems to me that getting the current
+thread handle with GetCurrentThread() is sufficient, and it seems to work
+perfectly fine, so maybe DuplicateHandle was just plain useless to begin with ?
+
+------------------------------------
+- In private.c, added some code at the beginning of ptw32_processInitialize
+to detect the case of multiple calls to ptw32_processInitialize.
+
+Rational: In order to debug pthread-win32, it is easier to compile
+it as a regular library (it is not possible to debug DLL's on winCE).
+In that case, the application must call ptw32_rocessInitialize()
+explicitely, to initialize pthread-win32. It is safer in this circumstance
+to handle the case where ptw32_processInitialize() is called on
+an already initialized library:
+
+int
+ptw32_processInitialize (void)
+{
+ if (ptw32_processInitialized) {
+ /*
+ * ignore if already initialized. this is useful for
+ * programs that uses a non-dll pthread
+ * library. such programs must call ptw32_processInitialize() explicitely,
+ * since this initialization routine is automatically called only when
+ * the dll is loaded.
+ */
+ return TRUE;
+ }
+ ptw32_processInitialized = TRUE;
+ [...]
+}
+
+------------------------------------
+- in private.c, if macro NEED_FTIME is defined, add routines to
+convert timespec_to_filetime and filetime_to_timespec, and modified
+code that was using _ftime() to use Win32 API instead.
+
+Rational: _ftime is not available on WinCE. It is necessary to use
+the native Win32 time API instead.
+
+Note: the routine timespec_to_filetime is provided as a convenience and a mean
+to test that filetime_to_timespec works, but it is not used by the library.
+
+------------------------------------
+- in semaphore.c, if macro NEED_SEM is defined, add code for the routines
+_increase_semaphore and _decrease_semaphore, and modify significantly
+the implementation of the semaphores so that it does not use CreateSemaphore.
+
+Rational: CreateSemaphore is not available on WinCE. I had to re-implement
+semaphores using mutexes and Events.
+
+Note: Only the semaphore routines that are used by pthread are implemented
+(i.e. signal conditions rely on a subset of the semaphores routines, and
+this subset works). Some other semaphore routines (e.g. sem_trywait) are
+not yet supported on my WinCE port (and since I don't need them, I am not
+planning to do anything about them).
+
+------------------------------------
+- in tsd.c, changed the code that defines TLS_OUT_OF_INDEXES
+
+/* TLS_OUT_OF_INDEXES not defined on WinCE */
+#ifndef TLS_OUT_OF_INDEXES
+#define TLS_OUT_OF_INDEXES 0xffffffff
+#endif
+
+Rational: TLS_OUT_OF_INDEXES is not defined in any standard include file
+on WinCE.
+
+------------------------------------
+- added file need_errno.h
+
+Rational: On WinCE, there is no errno.h file. need_errno.h is just a
+copy of windows version of errno.h, with minor modifications due to the fact
+that some of the error codes are defined by the WinCE socket library.
+In pthread.h, if NEED_ERRNO is defined, the file need_errno.h is
+included (instead of <errno.h>).

+#
+# Usage:
+# Set to any value in the range: 0 <= value < 2^wordsize.
+# Set to 0 to emulate reusable thread ID behaviour like Linux or *BSD.
+# Set to 1 for unique thread IDs like Solaris (this is the default).
+# Set to some factor of 2^wordsize to emulate smaller word size types

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

+<P STYLE="margin-left: 2cm">Windows NT: Values -7, -6, -5, -4, -3, 3,
+4, 5, and 6 are not supported.</P>
+<P STYLE="margin-left: 2cm">As you can see, the real priority levels
+available to any individual Win32 thread are non-contiguous.</P>
+<P STYLE="margin-left: 2cm">An application using Pthreads-w32 should
+not make assumptions about the numbers used to represent thread
+priority levels, except that they are monotonic between the values
+returned by sched_get_priority_min() and sched_get_priority_max().
+E.g. Windows 95, 98, NT, 2000, XP make available a non-contiguous
+range of numbers between -15 and 15, while at least one version of
+WinCE (3.0) defines the minimum priority (THREAD_PRIORITY_LOWEST) as
+5, and the maximum priority (THREAD_PRIORITY_HIGHEST) as 1.</P>
+<P STYLE="margin-left: 2cm">Internally, pthreads-win32 maps any
+priority levels between THREAD_PRIORITY_IDLE and
+THREAD_PRIORITY_LOWEST to THREAD_PRIORITY_LOWEST, or between
+THREAD_PRIORITY_TIME_CRITICAL and THREAD_PRIORITY_HIGHEST to
+THREAD_PRIORITY_HIGHEST. Currently, this also applies to
+REALTIME_PRIORITY_CLASS even if levels -7, -6, -5, -4, -3, 3, 4, 5,
+and 6 are supported.</P>
+<P STYLE="margin-left: 2cm">If it wishes, a Win32 application using
+pthreads-w32 can use the Win32 defined priority macros
+THREAD_PRIORITY_IDLE through THREAD_PRIORITY_TIME_CRITICAL.</P>

+<P>These two functions provide hooks into the <A HREF="pthread_cancel.html"><B>pthread_cancel</B></A>()
+mechanism that will allow you to wait on a Windows handle and make it
+a cancellation point. Both functions block until either the given

+has been called. They are implemented using <B>WaitForMultipleObjects</B>

+is the target of <A HREF="pthread_cancel.html"><B>pthread_cancel</B></A>().
+These routines may be called from Win32 native threads but
+<A HREF="pthread_cancel.html"><B>pthread_cancel</B></A>() will

+<P>The specification of the <I>stackaddr</I> attribute presents
+several ambiguities that make portable use of these interfaces
+impossible. The description of the single address parameter as a
+"stack" does not specify a particular relationship between
+the address and the "stack" implied by that address. For
+example, the address may be taken as the low memory address of a
+buffer intended for use as a stack, or it may be taken as the address
+to be used as the initial stack pointer register value for the new
+thread. These two are not the same except for a machine on which the
+stack grows "up" from low memory to high, and on which a
+"push" operation first stores the value in memory and then
+increments the stack pointer register. Further, on a machine where
+the stack grows "down" from high memory to low,
+interpretation of the address as the "low memory" address
+requires a determination of the intended size of the stack.
+IEEE Std 1003.1-2001 has introduced the new interfaces
+<A HREF="pthread_attr_setstack.html"><B>pthread_attr_setstack</B>(3)</A>
+and <A HREF="pthread_attr_getstack.html"><B>pthread_attr_getstack</B>(3)</A>

+<P>Cancellation is the mechanism by which a thread can terminate the
+execution of another thread. More precisely, a thread can send a
+cancellation request to another thread. Depending on its settings,
+the target thread can then either ignore the request, honor it
+immediately, or defer it until it reaches a cancellation point.
+</P>
+<P>When a thread eventually honors a cancellation request, it
+performs as if <B>pthread_exit(PTHREAD_CANCELED)</B> has been called
+at that point: all cleanup handlers are executed in reverse order,
+destructor functions for thread-specific data are called, and finally
+the thread stops executing with the return value <B>PTHREAD_CANCELED</B>.
+See <A HREF="pthread_exit.html"><B>pthread_exit</B>(3)</A> for more
+information.
+</P>
+<P><B>pthread_cancel</B> sends a cancellation request to the thread
+denoted by the <I>thread</I> argument.
+</P>
+<P><B>pthread_setcancelstate</B> changes the cancellation state for
+the calling thread -- that is, whether cancellation requests are
+ignored or not. The <I>state</I> argument is the new cancellation
+state: either <B>PTHREAD_CANCEL_ENABLE</B> to enable cancellation, or
+<B>PTHREAD_CANCEL_DISABLE</B> to disable cancellation (cancellation
+requests are ignored). If <I>oldstate</I> is not <B>NULL</B>, the
+previous cancellation state is stored in the location pointed to by
+<I>oldstate</I>, and can thus be restored later by another call to
+<B>pthread_setcancelstate</B>.
+</P>
+<P><B>pthread_setcanceltype</B> changes the type of responses to
+cancellation requests for the calling thread: asynchronous
+(immediate) or deferred. The <I>type</I> argument is the new
+cancellation type: either <B>PTHREAD_CANCEL_ASYNCHRONOUS</B> to
+cancel the calling thread as soon as the cancellation request is
+received, or <B>PTHREAD_CANCEL_DEFERRED</B> to keep the cancellation
+request pending until the next cancellation point. If <I>oldtype</I>
+is not <B>NULL</B>, the previous cancellation state is stored in the
+location pointed to by <I>oldtype</I>, and can thus be restored later
+by another call to <B>pthread_setcanceltype</B>.
+</P>
+<P><B>Pthreads-w32</B> provides two levels of support for
+<B>PTHREAD_CANCEL_ASYNCHRONOUS</B>: full and partial. Full support
+requires an additional DLL and driver be installed on the Windows
+system (see the See Also section below) that allows blocked threads
+to be cancelled immediately. Partial support means that the target
+thread will not cancel until it resumes execution naturally. Partial
+support is provided if either the DLL or the driver are not
+automatically detected by the pthreads-w32 library at run-time.</P>
+<P>Threads are always created by <A HREF="pthread_create.html"><B>pthread_create</B>(3)</A>
+with cancellation enabled and deferred. That is, the initial
+cancellation state is <B>PTHREAD_CANCEL_ENABLE</B> and the initial
+type is <B>PTHREAD_CANCEL_DEFERRED</B>.
+</P>
+<P>Cancellation points are those points in the program execution
+where a test for pending cancellation requests is performed and
+cancellation is executed if positive. The following POSIX threads
+functions are cancellation points:

+<BR><A HREF="pthreadCancelableTimedWait.html">pthreadCancelableTimedWait()</A></P>
+<P>All other POSIX threads functions are guaranteed not to be
+cancellation points. That is, they never perform cancellation in
+deferred cancellation mode.
+</P>

+<P>Cleanup handlers are functions that get called when a thread
+terminates, either by calling <A HREF="pthread_exit.html"><B>pthread_exit</B>(3)</A>
+or because of cancellation. Cleanup handlers are installed and
+removed following a stack-like discipline.
+</P>
+<P>The purpose of cleanup handlers is to free the resources that a
+thread may hold at the time it terminates. In particular, if a thread
+exits or is cancelled while it owns a locked mutex, the mutex will
+remain locked forever and prevent other threads from executing
+normally. The best way to avoid this is, just before locking the
+mutex, to install a cleanup handler whose effect is to unlock the
+mutex. Cleanup handlers can be used similarly to free blocks
+allocated with <A HREF="malloc.html"><B>malloc</B>(3)</A> or close
+file descriptors on thread termination.
+</P>
+<P><B>pthread_cleanup_push</B> installs the <I>routine</I> function
+with argument <I>arg</I> as a cleanup handler. From this point on to
+the matching <B>pthread_cleanup_pop</B>, the function <I>routine</I>
+will be called with arguments <I>arg</I> when the thread terminates,
+either through <A HREF="pthread_exit.html"><B>pthread_exit</B>(3)</A>
+or by cancellation. If several cleanup handlers are active at that
+point, they are called in LIFO order: the most recently installed
+handler is called first.
+</P>
+<P><B>pthread_cleanup_pop</B> removes the most recently installed
+cleanup handler. If the <I>execute</I> argument is not 0, it also
+executes the handler, by calling the <I>routine</I> function with
+arguments <I>arg</I>. If the <I>execute</I> argument is 0, the
+handler is only removed but not executed.
+</P>
+<P>Matching pairs of <B>pthread_cleanup_push</B> and
+<B>pthread_cleanup_pop</B> must occur in the same function, at the
+same level of block nesting. Actually, <B>pthread_cleanup_push</B>
+and <B>pthread_cleanup_pop</B> are macros, and the expansion of
+<B>pthread_cleanup_push</B> introduces an open brace <B>{</B> with
+the matching closing brace <B>}</B> being introduced by the expansion
+of the matching <B>pthread_cleanup_pop</B>.

+<P>A condition (short for ‘‘condition variable’’) is a
+synchronization device that allows threads to suspend execution and
+relinquish the processors until some predicate on shared data is
+satisfied. The basic operations on conditions are: signal the
+condition (when the predicate becomes true), and wait for the
+condition, suspending the thread execution until another thread
+signals the condition.
+</P>
+<P>A condition variable must always be associated with a mutex, to
+avoid the race condition where a thread prepares to wait on a
+condition variable and another thread signals the condition just
+before the first thread actually waits on it.
+</P>
+<P><B>pthread_cond_init</B> initializes the condition variable <I>cond</I>,
+using the condition attributes specified in <I>cond_attr</I>, or
+default attributes if <I>cond_attr</I> is <B>NULL</B>.
+</P>
+<P>Variables of type <B>pthread_cond_t</B> can also be initialized
+statically, using the constant <B>PTHREAD_COND_INITIALIZER</B>. In
+the <B>Pthreads-w32</B> implementation, an application should still
+call <B>pthread_cond_destroy</B> at some point to ensure that any
+resources consumed by the condition variable are released.</P>
+<P><B>pthread_cond_signal</B> restarts one of the threads that are
+waiting on the condition variable <I>cond</I>. If no threads are
+waiting on <I>cond</I>, nothing happens. If several threads are
+waiting on <I>cond</I>, exactly one is restarted, but it is not
+specified which.
+</P>
+<P><B>pthread_cond_broadcast</B> restarts all the threads that are
+waiting on the condition variable <I>cond</I>. Nothing happens if no
+threads are waiting on <I>cond</I>.
+</P>
+<P><B>pthread_cond_wait</B> atomically unlocks the <I>mutex</I> (as
+per <B>pthread_unlock_mutex</B>) and waits for the condition variable
+<I>cond</I> to be signalled. The thread execution is suspended and
+does not consume any CPU time until the condition variable is
+signalled. The <I>mutex</I> must be locked by the calling thread on
+entrance to <B>pthread_cond_wait</B>. Before returning to the calling
+thread, <B>pthread_cond_wait</B> re-acquires <I>mutex</I> (as per
+<B>pthread_lock_mutex</B>).
+</P>
+<P>Unlocking the mutex and suspending on the condition variable is
+done atomically. Thus, if all threads always acquire the mutex before
+signalling the condition, this guarantees that the condition cannot
+be signalled (and thus ignored) between the time a thread locks the
+mutex and the time it waits on the condition variable.
+</P>
+<P><B>pthread_cond_timedwait</B> atomically unlocks <I>mutex</I> and
+waits on <I>cond</I>, as <B>pthread_cond_wait</B> does, but it also
+bounds the duration of the wait. If <I>cond</I> has not been
+signalled within the amount of time specified by <I>abstime</I>, the
+mutex <I>mutex</I> is re-acquired and <B>pthread_cond_timedwait</B>
+returns the error <B>ETIMEDOUT</B>. The <I>abstime</I> parameter
+specifies an absolute time, with the same origin as <A HREF="time.html"><B>time</B>(2)</A>
+and <A HREF="gettimeofday.html"><B>gettimeofday</B>(2)</A>.
+</P>
+<P><B>pthread_cond_destroy</B> destroys a condition variable, freeing
+the resources it might hold. No threads must be waiting on the
+condition variable on entrance to <B>pthread_cond_destroy</B>.</P>
+<H2><A HREF="#toc3" NAME="sect3">Cancellation</A></H2>
+<P><B>pthread_cond_wait</B> and <B>pthread_cond_timedwait</B> are
+cancellation points. If a thread is cancelled while suspended in one
+of these functions, the thread immediately resumes execution, then
+locks again the <I>mutex</I> argument to <B>pthread_cond_wait</B> and
+<B>pthread_cond_timedwait</B>, and finally executes the cancellation.
+Consequently, cleanup handlers are assured that <I>mutex</I> is
+locked when they are called.
+</P>
+<H2><A HREF="#toc4" NAME="sect4">Async-signal Safety</A></H2>
+<P>The condition functions are not async-signal safe, and should not
+be called from a signal handler. In particular, calling
+<B>pthread_cond_signal</B> or <B>pthread_cond_broadcast</B> from a
+signal handler may deadlock the calling thread.
+</P>

+<P>Programs often need global or static variables that have different
+values in different threads. Since threads share one memory space,
+this cannot be achieved with regular variables. Thread-specific data
+is the POSIX threads answer to this need.
+</P>
+<P>Each thread possesses a private memory block, the thread-specific
+data area, or TSD area for short. This area is indexed by TSD keys.
+The TSD area associates values of type <B>void *</B> to TSD keys. TSD
+keys are common to all threads, but the value associated with a given
+TSD key can be different in each thread.
+</P>
+<P>For concreteness, the TSD areas can be viewed as arrays of <B>void
+*</B> pointers, TSD keys as integer indices into these arrays, and
+the value of a TSD key as the value of the corresponding array
+element in the calling thread.
+</P>
+<P>When a thread is created, its TSD area initially associates <B>NULL</B>
+with all keys.
+</P>
+<P><B>pthread_key_create</B> allocates a new TSD key. The key is
+stored in the location pointed to by <I>key</I>. There is a limit of
+<B>PTHREAD_KEYS_MAX</B> on the number of keys allocated at a given
+time. The value initially associated with the returned key is <B>NULL</B>
+in all currently executing threads.
+</P>
+<P>The <I>destr_function</I> argument, if not <B>NULL</B>, specifies
+a destructor function associated with the key. When a thread
+terminates via <B>pthread_exit</B> or by cancellation, <I>destr_function</I>
+is called with arguments the value associated with the key in that
+thread. The <I>destr_function</I> is not called if that value is <B>NULL</B><SPAN STYLE="font-weight: medium">
+or the key has been deleted</SPAN>. The order in which destructor
+functions are called at thread termination time is unspecified.
+</P>
+<P>Before the destructor function is called, the <B>NULL</B> value is
+associated with the key in the current thread. A destructor function
+might, however, re-associate non- <B>NULL</B> values to that key or
+some other key. To deal with this, if after all the destructors have
+been called for all non- <B>NULL</B> values, there are still some
+non- <B>NULL</B> values with associated destructors, then the process
+is repeated.</P>
+<P><B>pthread_key_delete</B> deallocates a TSD key. It does not check
+whether non- <B>NULL</B> values are associated with that key in the
+currently executing threads, nor call the destructor function
+associated with the key.
+</P>
+<P><B>pthread_setspecific</B> changes the value associated with <I>key</I>
+in the calling thread, storing the given <I>pointer</I> instead.
+</P>
+<P><B>pthread_getspecific</B> returns the value currently associated
+with <I>key</I> in the calling thread.
+</P>
+<P>The routines <B>pthread_setspecific</B>, <B>pthread_getspecific</B>,
+and <B>pthread_key_delete</B> can be called from <I>destr_function</I>
+targeting any valid key including the key on which <I>destr_function</I>
+is currently operating. If <B>pthread_getspecific</B> is called on
+the key whose thread specific data is being destroyed, the value NULL
+is returned, unless <B>pthread_setspecific</B> was called previously
+on that key from within <I>destr_function</I> to set the value to
+non-NULL. For some implementations the effect of calling
+<B>pthread_setspecific</B> from within <I>destr_function</I> can be

+<P>In any implementation, for <B>sigwait</B> to work reliably, the
+signals being waited for must be blocked in all threads, not only in
+the calling thread, since otherwise the POSIX semantics for signal
+delivery do not guarantee that it’s the thread doing the <B>sigwait</B>
+that will receive the signal. The best way to achieve this is to
+block those signals before any threads are created, and never unblock
+them in the program other than by calling <B>sigwait</B>. This works
+because all threads inherit their initial sigmask from their creating
+thread.</P>
+<H2><A HREF="#toc9" NAME="sect9">Bugs</A></H2>
+<P><B>Pthreads-w32</B> does not implement signals yet and so these
+routines have almost no use except to prevent the compiler or linker
+from complaining. <B>pthread_kill</B> is useful in determining if the
+thread is a valid thread, but since many threads implementations
+reuse thread IDs, the valid thread may no longer be the thread you
+think it is, and so this method of determining thread validity is not
+portable, and very risky. <B>Pthreads-w32</B> from version 1.0.0
+onwards implements pseudo-unique thread IDs, so applications that use
+this technique (but really shouldn't) have some protection.</P>

+<P>A mutex is a MUTual EXclusion device, and is useful for protecting
+shared data structures from concurrent modifications, and
+implementing critical sections and monitors.
+</P>
+<P>A mutex has two possible states: unlocked (not owned by any
+thread), and locked (owned by one thread). A mutex can never be owned
+by two different threads simultaneously. A thread attempting to lock
+a mutex that is already locked by another thread is suspended until
+the owning thread unlocks the mutex first.
+</P>
+<P><B>pthread_mutex_init</B> initializes the mutex object pointed to
+by <I>mutex</I> according to the mutex attributes specified in
+<I>mutexattr</I>. If <I>mutexattr</I> is <B>NULL</B>, default
+attributes are used instead.
+</P>
+<P>The type of a mutex determines whether it can be locked again by a
+thread that already owns it. The default type is “normal”. See
+<A HREF="pthread_mutexattr_init.html"><B>pthread_mutexattr_init</B>(3)</A>
+for more information on mutex attributes.
+</P>
+<P>Variables of type <B>pthread_mutex_t</B> can also be initialized
+statically, using the constants <B>PTHREAD_MUTEX_INITIALIZER</B> (for
+normal “fast” mutexes), <B>PTHREAD_RECURSIVE_MUTEX_INITIALIZER</B>
+(for recursive mutexes), and <B>PTHREAD_ERRORCHECK_MUTEX_INITIALIZER</B>
+(for error checking mutexes). <SPAN STYLE="font-weight: medium"> In
+the <B>Pthreads-w32</B> implementation, an application should still
+call <B>pthread_mutex_destroy</B> at some point to ensure that any
+resources consumed by the mutex are released.</SPAN></P>
+<P><B>pthread_mutex_lock</B> locks the given mutex. If the mutex is
+currently unlocked, it becomes locked and owned by the calling
+thread, and <B>pthread_mutex_lock</B> returns immediately. If the
+mutex is already locked by another thread, <B>pthread_mutex_lock</B>
+suspends the calling thread until the mutex is unlocked.
+</P>
+<P>If the mutex is already locked by the calling thread, the behavior
+of <B>pthread_mutex_lock</B> depends on the type of the mutex. If the
+mutex is of the “normal” type, the calling thread is suspended
+until the mutex is unlocked, thus effectively causing the calling
+thread to deadlock. If the mutex is of the ‘‘error checking’’
+type, <B>pthread_mutex_lock</B> returns immediately with the error
+code <B>EDEADLK</B>. If the mutex is of the ‘‘recursive’’
+type, <B>pthread_mutex_lock</B> succeeds and returns immediately,
+recording the number of times the calling thread has locked the
+mutex. An equal number of <B>pthread_mutex_unlock</B> operations must
+be performed before the mutex returns to the unlocked state.
+</P>
+<P><B>pthread_mutex_trylock</B> behaves identically to
+<B>pthread_mutex_lock</B>, except that it does not block the calling
+thread if the mutex is already locked by another thread (or by the
+calling thread in the case of a “normal” mutex). Instead,
+<B>pthread_mutex_trylock</B> returns immediately with the error code
+<B>EBUSY</B>.
+</P>
+<P><B>pthread_mutex_timedlock</B> behaves identically to
+<B>pthread_mutex_lock</B>, except that if it cannot acquire the lock
+before the <I>abs_timeout</I> time, the call returns with the error
+code <B>ETIMEDOUT</B>. If the mutex can be locked immediately it is,
+and the <B>abs_timeout</B> parameter is ignored.</P>
+<P><B>pthread_mutex_unlock</B> unlocks the given mutex. The mutex is
+assumed to be locked and owned by the calling thread on entrance to
+<B>pthread_mutex_unlock</B>. If the mutex is of the “normal”
+type, <B>pthread_mutex_unlock</B> always returns it to the unlocked
+state. If it is of the ‘‘recursive’’ type, it decrements the
+locking count of the mutex (number of <B>pthread_mutex_lock</B>
+operations performed on it by the calling thread), and only when this
+count reaches zero is the mutex actually unlocked.
+</P>
+<P>On ‘‘error checking’’ mutexes, <B>pthread_mutex_unlock</B>
+actually checks at run-time that the mutex is locked on entrance, and
+that it was locked by the same thread that is now calling
+<B>pthread_mutex_unlock</B>. If these conditions are not met, an
+error code is returned and the mutex remains unchanged. ‘‘Normal’’
+mutexes perform no such checks, thus allowing a locked mutex to be
+unlocked by a thread other than its owner. This is non-portable
+behavior and is not meant to be used as a feature.</P>
+<P><B>pthread_mutex_destroy</B> destroys a mutex object, freeing the
+resources it might hold. The mutex must be unlocked on entrance.</P>
+<H2><A HREF="#toc3" NAME="sect3">Cancellation</A></H2>
+<P>None of the mutex functions is a cancellation point, not even
+<B>pthread_mutex_lock</B>, in spite of the fact that it can suspend a
+thread for arbitrary durations. This way, the status of mutexes at
+cancellation points is predictable, allowing cancellation handlers to
+unlock precisely those mutexes that need to be unlocked before the
+thread stops executing. Consequently, threads using deferred
+cancellation should never hold a mutex for extended periods of time.
+</P>
+<H2><A HREF="#toc4" NAME="sect4">Async-signal Safety</A></H2>
+<P>The mutex functions are not async-signal safe. What this means is
+that they should not be called from a signal handler. In particular,
+calling <B>pthread_mutex_lock</B> or <B>pthread_mutex_unlock</B> from
+a signal handler may deadlock the calling thread.
+</P>
+<H2><A HREF="#toc5" NAME="sect5">Return Value</A></H2>

+<P>Mutex attributes can be specified at mutex creation time, by
+passing a mutex attribute object as second argument to
+<A HREF="pthread_mutex_init.html"><B>pthread_mutex_init</B>(3)</A> .
+Passing <B>NULL</B> is equivalent to passing a mutex attribute object
+with all attributes set to their default values.
+</P>
+<P><B>pthread_mutexattr_init</B> initializes the mutex attribute
+object <I>attr</I> and fills it with default values for the
+attributes.
+</P>
+<P><B>pthread_mutexattr_destroy</B> destroys a mutex attribute
+object, which must not be reused until it is reinitialized.</P>
+<P>The following mutex types are supported:</P>
+<P STYLE="margin-left: 2cm"><B>PTHREAD_MUTEX_NORMAL</B> - for
+‘‘fast’’ mutexes.</P>
+<P STYLE="margin-left: 2cm"><B>PTHREAD_MUTEX_RECURSIVE</B> - for
+‘‘recursive’’ mutexes.</P>
+<P STYLE="margin-left: 2cm"><B>PTHREAD_MUTEX_ERRORCHECK</B> - for
+‘‘error checking’’ mutexes.</P>
+<P>The mutex type determines what happens if a thread attempts to
+lock a mutex it already owns with <A HREF="pthread_mutex_lock.html"><B>pthread_mutex_lock</B>(3)</A>
+. If the mutex is of the “normal” or “fast” type,
+<A HREF="pthread_mutex_lock.html"><B>pthread_mutex_lock</B>(3)</A>
+simply suspends the calling thread forever. If the mutex is of the
+‘‘error checking’’ type, <A HREF="pthread_mutex_lock.html"><B>pthread_mutex_lock</B>(3)</A>
+returns immediately with the error code <B>EDEADLK</B>. If the mutex
+is of the ‘‘recursive’’ type, the call to
+<A HREF="pthread_mutex_lock.html"><B>pthread_mutex_lock</B>(3)</A>
+returns immediately with a success return code. The number of times
+the thread owning the mutex has locked it is recorded in the mutex.
+The owning thread must call <A HREF="pthread_mutex_unlock.html"><B>pthread_mutex_unlock</B>(3)</A>
+the same number of times before the mutex returns to the unlocked
+state.
+</P>
+<P>The default mutex type is <B>PTHREAD_MUTEX_NORMAL</B></P>

+<P STYLE="margin-left: 2cm"><B>PTHREAD_MUTEX_ERRORCHECK_NP</B></P>

+initialized.

+Whereas all threads created via a call to pthread_create have a POSIX

+threads that interact through the Pthreads API also generate a POSIX
+thread ID and thread state when and if necessary. This provides full
+<SPAN LANG="en-GB">reciprocity</SPAN> between Win32 and POSIX
+threads. Win32 native threads that generate a POSIX thread ID and

+<P>Any Win32 native thread may call <B>pthread_self</B> directly to
+return it's POSIX thread identifier. The ID and state will be
+generated if it does not already exist. Win32 native threads do not

+<P>Cancellation is the mechanism by which a thread can terminate the
+execution of another thread. More precisely, a thread can send a
+cancellation request to another thread. Depending on its settings,
+the target thread can then either ignore the request, honor it
+immediately, or defer it until it reaches a cancellation point.
+</P>
+<P>When a thread eventually honors a cancellation request, it
+performs as if <B>pthread_exit(PTHREAD_CANCELED)</B> has been called
+at that point: all cleanup handlers are executed in reverse order,
+destructor functions for thread-specific data are called, and finally
+the thread stops executing with the return value <B>PTHREAD_CANCELED</B>.
+See <A HREF="pthread_exit.html"><B>pthread_exit</B>(3)</A> for more
+information.
+</P>
+<P><B>pthread_cancel</B> sends a cancellation request to the thread
+denoted by the <I>thread</I> argument.
+</P>
+<P><B>pthread_setcancelstate</B> changes the cancellation state for
+the calling thread -- that is, whether cancellation requests are
+ignored or not. The <I>state</I> argument is the new cancellation
+state: either <B>PTHREAD_CANCEL_ENABLE</B> to enable cancellation, or
+<B>PTHREAD_CANCEL_DISABLE</B> to disable cancellation (cancellation
+requests are ignored). If <I>oldstate</I> is not <B>NULL</B>, the
+previous cancellation state is stored in the location pointed to by
+<I>oldstate</I>, and can thus be restored later by another call to
+<B>pthread_setcancelstate</B>.
+</P>
+<P><B>pthread_setcanceltype</B> changes the type of responses to
+cancellation requests for the calling thread: asynchronous
+(immediate) or deferred. The <I>type</I> argument is the new
+cancellation type: either <B>PTHREAD_CANCEL_ASYNCHRONOUS</B> to
+cancel the calling thread as soon as the cancellation request is
+received, or <B>PTHREAD_CANCEL_DEFERRED</B> to keep the cancellation
+request pending until the next cancellation point. If <I>oldtype</I>
+is not <B>NULL</B>, the previous cancellation state is stored in the
+location pointed to by <I>oldtype</I>, and can thus be restored later
+by another call to <B>pthread_setcanceltype</B>.
+</P>
+<P><B>Pthreads-w32</B> provides two levels of support for
+<B>PTHREAD_CANCEL_ASYNCHRONOUS</B>: full and partial. Full support
+requires an additional DLL and driver be installed on the Windows
+system (see the See Also section below) that allows blocked threads
+to be cancelled immediately. Partial support means that the target
+thread will not cancel until it resumes execution naturally. Partial
+support is provided if either the DLL or the driver are not
+automatically detected by the pthreads-w32 library at run-time.</P>

+<P>Unbound threads in a process may or may not be required to be

+that a sufficient number of threads are active so that the process
+can continue to make progress. While this conserves system resources,
+it may not produce the most effective level of concurrency.
+</P>
+<P>The <B>pthread_setconcurrency</B> function allows an application
+to inform the threads implementation of its desired concurrency
+level, <I>new_level</I>. The actual level of concurrency provided by
+the implementation as a result of this function call is unspecified.
+</P>
+<P>If <I>new_level</I> is zero, it causes the implementation to
+maintain the concurrency level at its discretion as if

+</P>
+<P>The <B>pthread_getconcurrency</B> function shall return the value
+set by a previous call to the <B>pthread_setconcurrency</B> function.
+If the <B>pthread_setconcurrency</B> function was not previously
+called, this function shall return zero to indicate that the
+implementation is maintaining the concurrency level.
+</P>
+<P>A call to <B>pthread_setconcurrency</B> shall inform the
+implementation of its desired concurrency level. The implementation
+shall use this as a hint, not a requirement.

+<P>If an implementation does not support multiplexing of user threads
+on top of several kernel-scheduled entities, the
+<B>pthread_setconcurrency</B> and <B>pthread_getconcurrency</B>
+functions are provided for source code compatibility but they shall
+have no effect when called. To maintain the function semantics, the

+is called so that a subsequent call to <B>pthread_getconcurrency</B>
+shall return the same value.

+<P>Semaphores are counters for resources shared between threads. The
+basic operations on semaphores are: increment the counter atomically,
+and wait until the counter is non-null and decrement it atomically.
+</P>
+<P><B>sem_init</B> initializes the semaphore object pointed to by
+<I>sem</I>. The count associated with the semaphore is set initially
+to <I>value</I>. The <I>pshared</I> argument indicates whether the
+semaphore is local to the current process ( <I>pshared</I> is zero)
+or is to be shared between several processes ( <I>pshared</I> is not
+zero).</P>
+<P><B>Pthreads-w32</B> currently does not support process-shared
+semaphores, thus <B>sem_init</B> always returns with error <B>EPERM</B>
+if <I>pshared</I> is not zero.
+</P>
+<P><B>sem_wait</B> atomically decrements <I>sem</I>'s count if it is
+greater than 0 and returns immediately or it suspends the calling
+thread until it can resume following a call to <B>sem_post</B> or
+<B>sem_post_multiple</B>.</P>
+<P><B>sem_timedwait</B> atomically decrements <I>sem</I>'s count if
+it is greater than 0 and returns immediately, or it suspends the
+calling thread. If <I>abstime</I> time arrives before the thread can
+resume following a call to <B>sem_post</B> or <B>sem_post_multiple</B>,
+then <B>sem_timedwait</B> returns with a return code of -1 after
+having set <B>errno</B> to <B>ETIMEDOUT</B>. If the call can return
+without suspending then <I>abstime</I> is not checked.</P>
+<P><B>sem_trywait</B> atomically decrements <I>sem</I>'s count if it
+is greater than 0 and returns immediately, or it returns immediately
+with a return code of -1 after having set <B>errno</B> to <B>EAGAIN</B>.
+<B>sem_trywait</B> never blocks.</P>
+<P><B>sem_post</B> either releases one thread if there are any
+waiting on <I>sem</I>, or it atomically increments <I>sem</I>'s
+count.</P>
+<P><B>sem_post_multiple</B> either releases multiple threads if there
+are any waiting on <I>sem</I> and/or it atomically increases <I>sem</I>'s
+count. If there are currently <I>n</I> waiters, where <I>n</I> the
+largest number less than or equal to <I>number</I>, then <I>n</I>
+waiters are released and <I>sem</I>'s count is incremented by <I>number</I>
+minus <I>n</I>.</P>
+<P><B>sem_getvalue</B> stores in the location pointed to by <I>sval</I>
+the current count of the semaphore <I>sem</I>. In the <B>Pthreads-w32</B>
+implementation: if the value returned in <I>sval</I> is greater than
+or equal to 0 it was the <I>sem</I>'s count at some point during the
+call to <B>sem_getvalue</B>. If the value returned in <I>sval</I> is
+less than 0 then it's absolute value represents the number of threads
+waiting on <I>sem</I> at some point during the call to <B>sem_getvalue.
+</B>POSIX does not require an implementation of <B>sem_getvalue</B>
+to return a value in <I>sval</I> that is less than 0, but if it does
+then it's absolute value must represent the number of waiters.</P>
+<P><B>sem_destroy</B> destroys a semaphore object, freeing the
+resources it might hold. No threads should be waiting on the
+semaphore at the time <B>sem_destroy</B> is called.</P>

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

+ * POSIX 1003.1-2001 Options
+ * =========================
+ *
+ * Options are normally set in <unistd.h>, which is not provided
+ * with pthreads-win32.
+ *
+ * For conformance with the Single Unix Specification (version 3), all of the
+ * options below are defined, and have a value of either -1 (not supported)
+ * or 200112L (supported).
+ *
+ * These options can neither be left undefined nor have a value of 0, because
+ * either indicates that sysconf(), which is not implemented, may be used at
+ * runtime to check the status of the option.
+ *
+ * _POSIX_THREADS (== 200112L)
+ * If == 200112L, you can use threads
+ *
+ * _POSIX_THREAD_ATTR_STACKSIZE (== 200112L)
+ * If == 200112L, you can control the size of a thread's
+ * stack
+ * pthread_attr_getstacksize
+ * pthread_attr_setstacksize
+ *
+ * _POSIX_THREAD_ATTR_STACKADDR (== -1)
+ * If == 200112L, you can allocate and control a thread's
+ * stack. If not supported, the following functions
+ * will return ENOSYS, indicating they are not
+ * supported:
+ * pthread_attr_getstackaddr
+ * pthread_attr_setstackaddr
+ *
+ * _POSIX_THREAD_PRIORITY_SCHEDULING (== -1)
+ * If == 200112L, you can use realtime scheduling.
+ * This option indicates that the behaviour of some
+ * implemented functions conforms to the additional TPS
+ * requirements in the standard. E.g. rwlocks favour
+ * writers over readers when threads have equal priority.
+ *
+ * _POSIX_THREAD_PRIO_INHERIT (== -1)
+ * If == 200112L, you can create priority inheritance
+ * mutexes.
+ * pthread_mutexattr_getprotocol +
+ * pthread_mutexattr_setprotocol +
+ *
+ * _POSIX_THREAD_PRIO_PROTECT (== -1)
+ * If == 200112L, you can create priority ceiling mutexes
+ * Indicates the availability of:
+ * pthread_mutex_getprioceiling
+ * pthread_mutex_setprioceiling
+ * pthread_mutexattr_getprioceiling
+ * pthread_mutexattr_getprotocol +
+ * pthread_mutexattr_setprioceiling
+ * pthread_mutexattr_setprotocol +
+ *
+ * _POSIX_THREAD_PROCESS_SHARED (== -1)
+ * If set, you can create mutexes and condition
+ * variables that can be shared with another
+ * process.If set, indicates the availability
+ * of:
+ * pthread_mutexattr_getpshared
+ * pthread_mutexattr_setpshared
+ * pthread_condattr_getpshared
+ * pthread_condattr_setpshared
+ *
+ * _POSIX_THREAD_SAFE_FUNCTIONS (== 200112L)
+ * If == 200112L you can use the special *_r library
+ * functions that provide thread-safe behaviour
+ *
+ * _POSIX_READER_WRITER_LOCKS (== 200112L)
+ * If == 200112L, you can use read/write locks
+ *
+ * _POSIX_SPIN_LOCKS (== 200112L)
+ * If == 200112L, you can use spin locks
+ *
+ * _POSIX_BARRIERS (== 200112L)
+ * If == 200112L, you can use barriers
+ *
+ * + These functions provide both 'inherit' and/or
+ * 'protect' protocol, based upon these macro
+ * settings.

+ * pthread_delay_np
+ *
+ * DESCRIPTION
+ *
+ * This routine causes a thread to delay execution for a specific period of time.
+ * This period ends at the current time plus the specified interval. The routine
+ * will not return before the end of the period is reached, but may return an
+ * arbitrary amount of time after the period has gone by. This can be due to
+ * system load, thread priorities, and system timer granularity.
+ *
+ * Specifying an interval of zero (0) seconds and zero (0) nanoseconds is
+ * allowed and can be used to force the thread to give up the processor or to
+ * deliver a pending cancelation request.
+ *
+ * The timespec structure contains the following two fields:
+ *
+ * tv_sec is an integer number of seconds.
+ * tv_nsec is an integer number of nanoseconds.
+ *
+ * Return Values
+ *
+ * If an error condition occurs, this routine returns an integer value indicating
+ * the type of error. Possible return values are as follows:
+ *
+ * 0
+ * Successful completion.
+ * [EINVAL]
+ * The value specified by interval is invalid.
+ *
+ * Example
+ *
+ * The following code segment would wait for 5 and 1/2 seconds
+ *
+ * struct timespec tsWait;
+ * int intRC;
+ *
+ * tsWait.tv_sec = 5;

+ * DOCPUBLIC
+ * The pthread_mutexattr_settype() and

+ *
+ * DESCRIPTION
+ * The pthread_mutexattr_settype() and
+ * pthread_mutexattr_gettype() functions respectively set and
+ * get the mutex type attribute. This attribute is set in the
+ * type parameter to these functions. The default value of the
+ * type attribute is PTHREAD_MUTEX_DEFAULT.
+ *
+ * The type of mutex is contained in the type attribute of the
+ * mutex attributes. Valid mutex types include:
+ *
+ * PTHREAD_MUTEX_NORMAL
+ * This type of mutex does not detect deadlock. A
+ * thread attempting to relock this mutex without
+ * first unlocking it will deadlock. Attempting to
+ * unlock a mutex locked by a different thread
+ * results in undefined behavior. Attempting to
+ * unlock an unlocked mutex results in undefined
+ * behavior.
+ *
+ * PTHREAD_MUTEX_ERRORCHECK
+ * This type of mutex provides error checking. A
+ * thread attempting to relock this mutex without
+ * first unlocking it will return with an error. A
+ * thread attempting to unlock a mutex which another
+ * thread has locked will return with an error. A
+ * thread attempting to unlock an unlocked mutex will
+ * return with an error.
+ *
+ * PTHREAD_MUTEX_DEFAULT
+ * Same as PTHREAD_MUTEX_NORMAL.
+ *
+ * PTHREAD_MUTEX_RECURSIVE
+ * A thread attempting to relock this mutex without
+ * first unlocking it will succeed in locking the
+ * mutex. The relocking deadlock which can occur with
+ * mutexes of type PTHREAD_MUTEX_NORMAL cannot occur
+ * with this type of mutex. Multiple locks of this
+ * mutex require the same number of unlocks to
+ * release the mutex before another thread can
+ * acquire the mutex. A thread attempting to unlock a
+ * mutex which another thread has locked will return
+ * with an error. A thread attempting to unlock an
+ * unlocked mutex will return with an error. This
+ * type of mutex is only supported for mutexes whose
+ * process shared attribute is
+ * PTHREAD_PROCESS_PRIVATE.
+ *
+ * RESULTS
+ * 0 successfully set attribute,
+ * EINVAL 'attr' or 'type' is invalid,

+ * ---------------------------------------------------------------------
+ *
+ * This solution was suggested by Alexander Terekhov, but any errors
+ * in the implementation are mine - [Ross Johnson]
+ *
+ * 1) The problem: threads doing a timedwait on a CV may expect to timeout
+ * at a specific absolute time according to a system timer. If the
+ * system clock is adjusted backwards then those threads sleep longer than
+ * expected. Also, pthreads-win32 converts absolute times to intervals in
+ * order to make use of the underlying Win32, and so waiting threads may
+ * awake before their proper abstimes.
+ *
+ * 2) We aren't able to distinquish between threads on timed or untimed waits,
+ * so we wake them all at the time of the adjustment so that they can
+ * re-evaluate their conditions and re-compute their timeouts.
+ *
+ * 3) We rely on correctly written applications for this to work. Specifically,
+ * they must be able to deal properly with spurious wakeups. That is,
+ * they must re-test their condition upon wakeup and wait again if
+ * the condition is not satisfied.

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

+ * How it works:
+ * A pthread_t is a struct (2x32 bit scalar types on IA-32, 2x64 bit on IA-64)
+ * which is normally passed/returned by value to/from pthreads routines.
+ * Applications are therefore storing a copy of the struct as it is at that
+ * time.
+ *
+ * The original pthread_t struct plus all copies of it contain the address of
+ * the thread state struct ptw32_thread_t_ (p), plus a reuse counter (x). Each
+ * ptw32_thread_t contains the original copy of it's pthread_t.
+ * Once malloced, a ptw32_thread_t_ struct is not freed until the process exits.
+ *
+ * The thread reuse stack is a simple LILO stack managed through a singly
+ * linked list element in the ptw32_thread_t.
+ *
+ * Each time a thread is destroyed, the ptw32_thread_t address is pushed onto the
+ * reuse stack after it's ptHandle's reuse counter has been incremented.
+ *
+ * The following can now be said from this:
+ * - two pthread_t's are identical if their ptw32_thread_t reference pointers
+ * are equal and their reuse counters are equal. That is,
+ *
+ * equal = (a.p == b.p && a.x == b.x)
+ *
+ * - a pthread_t copy refers to a destroyed thread if the reuse counter in
+ * the copy is not equal to the reuse counter in the original.
+ *
+ * threadDestroyed = (copy.x != ((ptw32_thread_t *)copy.p)->ptHandle.x)

+/*
+ * Possible future strategy for implementing pthread_kill()
+ * ========================================================
+ *
+ * Win32 does not implement signals.
+ * Signals are simply software interrupts.
+ * pthread_kill() asks the system to deliver a specified
+ * signal (interrupt) to a specified thread in the same
+ * process.
+ * Signals are always asynchronous (no deferred signals).
+ * Pthread-win32 has an async cancelation mechanism.
+ * A similar system can be written to deliver signals
+ * within the same process (on ix86 processors at least).
+ *
+ * Each thread maintains information about which
+ * signals it will respond to. Handler routines
+ * are set on a per-process basis - not per-thread.
+ * When signalled, a thread will check it's sigmask
+ * and, if the signal is not being ignored, call the
+ * handler routine associated with the signal. The
+ * thread must then (except for some signals) return to
+ * the point where it was interrupted.
+ *
+ * Ideally the system itself would check the target thread's
+ * mask before possibly needlessly bothering the thread
+ * itself. This could be done by pthread_kill(), that is,
+ * in the signaling thread since it has access to
+ * all pthread_t structures. It could also retrieve
+ * the handler routine address to minimise the target
+ * threads response overhead. This may also simplify
+ * serialisation of the access to the per-thread signal
+ * structures.
+ *
+ * pthread_kill() eventually calls a routine similar to
+ * ptw32_cancel_thread() which manipulates the target
+ * threads processor context to cause the thread to
+ * run the handler launcher routine. pthread_kill() must
+ * save the target threads current context so that the
+ * handler launcher routine can restore the context after
+ * the signal handler has returned. Some handlers will not
+ * return, eg. the default SIGKILL handler may simply
+ * call pthread_exit().
+ *
+ * The current context is saved in the target threads
+ * pthread_t structure.

+
+ * stress1.c (millisecondsFromNow): Remove limit 0 <= millisecs < 1000;
+ now works for -INT_MAX <= millisecs <= INT_MAX; not needed for
+ stress1.c but should be general anyway.
+
+2005-05-18 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * reuse2.c (main): Must use a read with memory barrier semantics
+ when polling 'done' to force the cache into coherence on MP systems.
+
+2005-05-15 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * detach1.c: New test.
+ * join1.c: Reduce sleep times.
+ * join0.c: Remove MSVCRT conditional compile - join should always
+ return the thread exit code.
+ * join1.c: Likewise.
+ * join2.c: Likewise.
+ * join3.c: Likewise.
+
+2005-04-18 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * condvar3.c: Remove locks from around signalling calls - should not
+ be required for normal operation and only serve to mask deficiencies;
+ ensure that CV destruction is not premature after removing guards.
+ * condvar3_1.c: Likewise.
+ * condvar3_2.c: Likewise.
+ * condvar3_3.c: Likewise.
+ * condvar4.c: Likewise.
+ * condvar5.c: Likewise.
+ * condvar6.c: Likewise.
+ * condvar7.c: Likewise.
+ * condvar8.c: Likewise.
+ * condvar9.c: Likewise.
+
+2005-04-11 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * once4.c: New test; tries to test priority adjustments
+ in pthread_once(); set priority class to realtime so that
+ any failures can be seen.
+
+2005-04-06 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * cleanup0.c: Fix unguarded global variable accesses.
+ * cleanup1.c: Likewise.
+ * cleanup2.c: Likewise.
+ * cleanup3.c: Likewise.
+ * once2.c: Likewise.
+ * once3.c: Likewise.
+
+2005-04-01 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * GNUmakefile: Add target to test linking static link library.
+ * Makefile: Likewise.
+ * self1.c: Run process attach/detach routines when static linked.
+
+2005-03-16 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * mutex5.c: Prevent optimiser from removing asserts.
+
+2005-03-12 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * once3.c: New test.
+
+2005-03-08 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * once2.c: New test.
+
+2004-11-19 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * Bmakefile: New makefile for Borland.
+ * Makefile (DLL_VER): Added.
+ * GNUmakefile (DLL_VER): Added.
+ * Wmakefile (DLL_VER): Added.
+
+2004-10-29 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * semaphore4.c: New test.
+ * semaphore4t.c: New test.
+ * Debug.dsp (et al): Created MSVC Workspace project to aid debugging.
+ * All: Many tests have been modified to work with the new pthread
+ ID type; some other corrections were made after some library
+ functions were semantically strengthened. For example,
+ pthread_cond_destroy() no longer destroys a busy CV, which
+ required minor redesigns of some tests, including some where
+ the mutex associated with the CV was not locked during
+ signaling and broadcasting.
+
+2004-10-23 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * condvar3.c: Fixed mutex operations that were incorrectly
+ placed in relation to their condition variable operations.
+ The error became evident after sem_destroy() was rewritten
+ and conditions for destroing the semaphore were tightened.
+ As a result, pthread_cond_destroy() was not able to
+ destroy the cv queueing sempahore.
+ * condvar3_1.c: Likewise.
+ * condvar3_2.c: Likewise.
+ * condvar4.c: Likewise.
+ * condvar5.c: Likewise.
+ * condvar6.c: Likewise.
+ * condvar7.c: Likewise.

+
+ * semaphore3.c: New test.
+
+2004-10-14 Ross Johnson <rpj@callisto.canberra.edu.au>
+
+ * rwlock7.c (main): Tidy up statistics reporting; randomise
+ update accesses.
+ * rwlock8.c: New test.
+
+2004-09-08 Alexandre Girao <alexgirao@gmail.com>
+
+ * cancel7.c (main): Win98 wants a valid (non-NULL) location

+ * 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).

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

+Running test cases in this directory
+------------------------------------
+
+These make scripts expect to be able to copy the dll, library
+and header files from this directory's parent directory,
+which should be the pthreads-win32 source directory.
+
+MS VC nmake
+-------------
+
+Run the target corresponding to the DLL version being tested:
+
+nmake clean VC
+
+or:
+
+nmake clean VS
+
+
+GNU GCC make
+------------
+
+Run "make clean" and then "make". See the "Known bugs" section
+in ..\README.
+
+
+Writing Test Cases
+------------------
+
+Tests written in this test suite should behave in the following manner:
+
+ * If a test fails, leave main() with a result of 1.
+
+ * If a test succeeds, leave main() with a result of 0.
+
+ * No diagnostic output should appear when the test is succeeding.
+ Diagnostic output may be emitted if something in the test
+ fails, to help determine the cause of the test failure.
+
+Notes:
+------
+
+Many test cases use knowledge of implementation internals which are supposed
+to be opaque to portable applications.

+Benchmarking
+------------
+There is a set a benchmarking programs in the
+"tests" directory. These should be runnable using the
+following command-lines corresponding to each of the possible
+library builds:
+
+MSVC:
+nmake clean VC-bench
+nmake clean VCE-bench
+nmake clean VSE-bench
+
+Mingw32:
+make clean GC-bench
+make clean GCE-bench
+
+UWIN:
+The benchtests are run as part of the testsuite.
+
+
+Mutex benchtests
+----------------
+
+benchtest1 - Lock plus unlock on an unlocked mutex.
+benchtest2 - Lock plus unlock on a locked mutex.
+benchtest3 - Trylock on a locked mutex.
+benchtest4 - Trylock plus unlock on an unlocked mutex.
+
+
+Each test times up to three alternate synchronisation
+implementations as a reference, and then times each of
+the four mutex types provided by the library. Each is
+described below:
+
+Simple Critical Section
+- uses a simple Win32 critical section. There is no
+additional overhead for this case as there is in the
+remaining cases.
+
+POSIX mutex implemented using a Critical Section
+- The old implementation which uses runtime adaptation
+depending on the Windows variant being run on. When
+the pthreads DLL was run on WinNT or higher then
+POSIX mutexes would use Win32 Critical Sections.
+
+POSIX mutex implemented using a Win32 Mutex
+- The old implementation which uses runtime adaptation
+depending on the Windows variant being run on. When
+the pthreads DLL was run on Win9x then POSIX mutexes
+would use Win32 Mutexes (because TryEnterCriticalSection
+is not implemented on Win9x).
+
+PTHREAD_MUTEX_DEFAULT
+PTHREAD_MUTEX_NORMAL
+PTHREAD_MUTEX_ERRORCHECK
+PTHREAD_MUTEX_RECURSIVE
+- The current implementation supports these mutex types.
+The underlying basis of POSIX mutexes is now the same
+irrespective of the Windows variant, and should therefore
+have consistent performance.
+
+
+Semaphore benchtests
+--------------------
+
+benchtest5 - Timing for various uncontended cases.
+
+
+In all benchtests, the operation is repeated a large
+number of times and an average is calculated. Loop
+overhead is measured and subtracted from all test times.

+ * Do we need to lock stdout or is it thread safe?
+ *
+ * Used:
+ * pthread_t
+ * pthread_attr_t
+ * pthread_create()
+ * pthread_join()
+ * pthread_mutex_t
+ * PTHREAD_MUTEX_INITIALIZER
+ * pthread_mutex_init() [not used now]
+ * pthread_mutex_destroy()
+ * pthread_mutex_lock()
+ * pthread_mutex_trylock()
+ * pthread_mutex_unlock()
+ *
+ * What this program does is establish a work queue (implemented using
+ * four mutexes for each thread). It then schedules work (by storing
+ * a number in 'todo') and releases the threads. When the work is done
+ * the threads will block. The program then repeats the same thing once
+ * more (just to test the logic) and when the work is done it destroyes
+ * the threads.
+ *
+ * The 'work' we do is simply burning CPU cycles in a loop.
+ * The 'todo' work queue is trivial - each threads pops one element
+ * off it by incrementing it, the poped number is the 'work' to do.
+ * When 'todo' reaches the limit (nwork) the queue is considered
+ * empty.
+ *
+ * The number displayed at the end is the amount of work each thread
+ * did, so we can see if the load was properly distributed.
+ *
+ * The program was written to test a threading setup (not seen here)
+ * rather than to demonstrate correct usage of the pthread facilities.
+ *
+ * Note how each thread is given access to a thread control structure
+ * (TC) which is used for communicating to/from the main program (e.g.
+ * the threads knows its 'id' and also filles in the 'work' done).

+ * Subject: invalid page fault when using LoadLibrary/FreeLibrary
+ *
+ * hi,
+ * for me, pthread.dll consistently causes an "invalid page fault in
+ * kernel32.dll" when I load it "explicitly"...to be precise, loading (with
+ * LoadLibrary) isn't a problem, it gives the error when I call FreeLibrary.
+ * I guess that the dll's cleanup must be causing the error.
+ *
+ * Implicit linkage of the dll has never given me this problem. Here's a
+ * program (console application) that gives me the error.
+ *
+ * I compile with: mingw32 (gcc-2.95 release), with the MSVCRT add-on (not
+ * that the compiler should make much difference in this case).
+ * PTHREAD.DLL: is the precompiled 1999-11-02 one (I tried an older one as
+ * well, with the same result).
+ *
+ * Fascinatingly, if you have your own dll (mycode.dll) which implicitly
+ * loads pthread.dll, and then do LoadLibrary/FreeLibrary on _this_ dll, the
+ * same thing happens.
+ *

+VERSIONINFO Resource
+
+The VERSIONINFO resource-definition statement creates a version-information
+resource. The resource contains such information about the file as its
+version number, its intended operating system, and its original filename.
+The resource is intended to be used with the Version Information functions.
+
+versionID VERSIONINFO fixed-info { block-statement...}
+
+versionID
+ Version-information resource identifier. This value must be 1.
+
+fixed-info
+ Version information, such as the file version and the intended operating
+ system. This parameter consists of the following statements.
+
+
+ Statement Description
+ --------------------------------------------------------------------------
+ FILEVERSION
+ version Binary version number for the file. The version
+ consists of two 32-bit integers, defined by four
+ 16-bit integers. For example, "FILEVERSION 3,10,0,61"
+ is translated into two doublewords: 0x0003000a and
+ 0x0000003d, in that order. Therefore, if version is
+ defined by the DWORD values dw1 and dw2, they need
+ to appear in the FILEVERSION statement as follows:
+ HIWORD(dw1), LOWORD(dw1), HIWORD(dw2), LOWORD(dw2).
+ PRODUCTVERSION
+ version Binary version number for the product with which the
+ file is distributed. The version parameter is two
+ 32-bit integers, defined by four 16-bit integers.
+ For more information about version, see the
+ FILEVERSION description.
+ FILEFLAGSMASK
+ fileflagsmask Bits in the FILEFLAGS statement are valid. If a bit
+ is set, the corresponding bit in FILEFLAGS is valid.
+ FILEFLAGSfileflags Attributes of the file. The fileflags parameter must
+ be the combination of all the file flags that are
+ valid at compile time. For 16-bit Windows, this
+ value is 0x3f.
+ FILEOSfileos Operating system for which this file was designed.
+ The fileos parameter can be one of the operating
+ system values given in the Remarks section.
+ FILETYPEfiletype General type of file. The filetype parameter can be
+ one of the file type values listed in the Remarks
+ section.
+ FILESUBTYPE
+ subtype Function of the file. The subtype parameter is zero
+ unless the type parameter in the FILETYPE statement
+ is VFT_DRV, VFT_FONT, or VFT_VXD. For a list of file
+ subtype values, see the Remarks section.
+
+block-statement
+ Specifies one or more version-information blocks. A block can contain
+ string information or variable information. For more information, see
+ StringFileInfo Block or VarFileInfo Block.
+
+Remarks
+
+To use the constants specified with the VERSIONINFO statement, you must
+include the Winver.h or Windows.h header file in the resource-definition file.
+
+The following list describes the parameters used in the VERSIONINFO statement:
+
+fileflags
+ A combination of the following values.
+
+ Value Description
+
+ VS_FF_DEBUG File contains debugging information or is compiled
+ with debugging features enabled.
+ VS_FF_PATCHED File has been modified and is not identical to the
+ original shipping file of the same version number.
+ VS_FF_PRERELEASE File is a development version, not a commercially
+ released product.
+ VS_FF_PRIVATEBUILD File was not built using standard release procedures.
+ If this value is given, the StringFileInfo block must
+ contain a PrivateBuild string.
+ VS_FF_SPECIALBUILD File was built by the original company using standard
+ release procedures but is a variation of the standard
+ file of the same version number. If this value is
+ given, the StringFileInfo block must contain a
+ SpecialBuild string.
+
+fileos
+ One of the following values.
+
+ Value Description
+

+ which the file was created. This string is required.
+ PrivateBuild Information about a private version of the file — for
+ example, "Built by TESTER1 on \TESTBED". This string
+ should be present only if VS_FF_PRIVATEBUILD is
+ specified in the fileflags parameter of the root

+ ProductName Name of the product with which the file is
+ distributed. This string is required.
+ ProductVersion Version of the product with which the file is
+ distributed — for example, "3.10" or "5.00.RC2".
+ This string is required.
+ SpecialBuild Text that indicates how this version of the file
+ differs from the standard version — for example,
+ "Private build for TESTER1 solving mouse problems
+ on M250 and M250E computers". This string should be
