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 (cf. previous release - this release is closer to Gottlob Frege's first posted design, but with cancellation and priority boosting added plus some other house-keeping). * 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, but see the BUGS file (bug #3). 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.
