@@ -1,3 +1,58 @@ +RELEASE 1.8.0 +------------- +(2005-04-26) + +General +------- + +This release back-ports all relevant bug fixes and new features of +release 2.4.0. The two releases thus far remain functionally the same. +The key difference is the efficiency of pthread_once where this routine +may be heavily used. + +Bugs fixed +---------- + +* Fix integer overrun error in pthread_mutex_timedlock() - missed when +sem_timedwait() was fixed in release 2.2.0. This rouitne no longer returns +ENOSUP 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 1.7.0 ------------- (2005-04-12) |
