        * win32_src/: Win32Condition.h, Win32ThreadBarrier.cpp: Converted
          to dos endings.

2005-11-15 18:31  robert

        * Make/makedefs: From Sean Spicer, compile fixes for Intel
          compiler.

2005-11-11 10:48  robert

        * Make/instrules: From Colin McDonald, build fix for Solaris.

2005-11-03 11:36  robert

        * win32_src/HandleHolder.h: From Thibault Genessay,

          "Under Windows, the current implementation of the operator bool()
          of the HandleHolder class can return true even if the handle is
          not valid. This happens when Win32 calls return NULL instead of
          INVALID_HANDLE_VALUE as expected by the operator bool().

          The modified file makes the OpenThreads::Thread::start() method
          return non-zero in this case, and should also ensure that other
          calls to Win32 functions returning handles are correctly checked.
           "

2005-09-28 15:02  robert

        * include/OpenThreads/Exports: From Chris Hanson, "Minor changes to
          support Win32 static library linking, when used in conjunction
          with static-enabled .dsp (forthcoming)."

2005-06-24 16:39  robert

        * Make/makedefs: From Colin McDonald:

              "Some makedefs fixes for Solaris:

              For multithreaded applications the -mt option must be
          specified on both
              the compile and link steps, to ensure correct behaviour.
          According to
              the Sun compiler documentation it sets REENTRANT flags in the
          system
              header files, and links the -lthread library in the correct
          order.

              When compiling shared libraries the -KPIC option should be
          specified.
              Although Solaris will handle shared libraries without
              position-independent code there is a performance penalty.
          The linker
              reference manual says: 'If a shared object is built from code
          that is
              not position-independent, the text segment will usually
          require a large
              number of relocations to be performed at runtime. Although
          the runtime
              linker is equipped to handle this, the system overhead this
          creates can
              cause serious performance degradation'."

2005-05-24 16:54  robert

        * win32_src/Win32Thread.cpp: Added pragma to remove depreacted API

        * include/OpenThreads/Thread, pthread_src/PThread.c++,
          sproc_src/SprocThread.c++, win32_src/Win32Thread.cpp: Renamed
          Thread::usleep(uint) to Thread::microSleep(uint) to avoid compile
          problems when usleep is defined by extenal dependencies.

          "speculatively" solve a crash that has been reported on the OSG
          that looked like an example of cancel() being called the thread
          was started.

          Win32ConditionPrivateData.h, Win32Thread.cpp,
          Win32ThreadBarrier.cpp: Thread cancelation support take 3 :-) *
          cancelEvent in Win32 thread implementation. Event is signaled in
          cancel() * testCancel() checks event (with
          WaitForSingleObject(cancelEvent, 0) ) * cooperativeWait( handle,
          timeout ) cheks cancelEvent besides handle   and exits if
          cancelEvent is signaled * Thread::cancel() has right semantics
          finally     - deffered - signal cancelEvent than wait for thread
          to exit    -  async - terminateThread unconditionally    -
          disable - do nothing

2003-08-29 12:03  bbralo

        * win32_src/Win32ThreadPrivateData.h: added cancelEvent member for

        * win32_src/: OpenThreads.dsp, WIN32Condition.cpp,
          Win32ConditionPrivateData.h, Win32Thread.cpp,
          Win32ThreadBarrier.cpp, Win32ThreadPrivateData.h: thread
          cancelation issues: * condition::wait and condition::broadcast()
          now uses WaitForMultipleObject API   with second handle being
          thread handle.  *to make this work change is made in
          thread::cancel   -reintroduced WaitForSingleObject but with
          shorter timeout this time.    This shold take care delays on exit
          * remove unneeded testCanlel() calls

2003-08-26 08:37  robertosfield

        * win32_src/Win32ConditionPrivateData.h: Moved position of Thread*

        * examples_src/simplethreader/: SimpleThreader.c++,
          ThreadObserver.c++, ThreadReporter.c++: Changed extension from
          c++ to cpp for VC to work.

2003-07-22 09:59  bbralo

        * examples_src/simplethreader/: SimpleThreader.cpp,
          ThreadObserver.cpp, ThreadReporter.cpp, simplethreader.dsp,
          simplethreader.plg: Changed extension from c++ to cpp for VC to
          work.  Added CurrentChecker() for testing of
          Thread::CurrentThread() workings.  Various WIN32 fixes

2003-07-22 09:57  bbralo

        * examples_src/simplethreader/: GNUmakefile, ThreadReporter.h:
          Changed extension from c++ to cpp for VC to work.  Added
          CurrentChecker() for testing of Thread::CurrentThread() workings.

        * include/OpenThreads/Thread, pthread_src/PThread.c++,
          pthread_src/PThreadPrivateData.h, win32_src/Win32Thread.cpp:
          Implement first pass at Thread::CurrentThread() to return a
          pointer to the current thread being executed.  If NULL, this
          probably means it's the main thread.  Also change Thread::yield
          -> Thread::Yield() and make it static.
