* QRecursiveMutexPrivate should not inherit from QMutexPrivateOlivier Goffart2011-10-311-2/+2

* QMutex is now just a pointerOlivier Goffart2011-07-291-113/+3
| | | | | | | | | | | | | | | | | | | | | | | | | And added a POD QBasicMutex. (QBasicMutex* can safely be static_cast'ed to QMutex*) The d pointer is not anymore always a QMutexPrivate. If d == 0x0: the mutex is unlocked If d == 0x1: the mutex is locked, uncontended On linux: if d == 0x3: the mutex is locked contended, waiting on a futex If d is a pointer, it is a recursive mutex. On non-linux platforms: When a thread tries to lock a mutex for which d == 0x1, it will try to assing it a QMutexPrivated (allocated from a freelist) in order to wait for it.

* Do not allow multiple threads to acquire a QMutexBradley T. Hughes2011-05-101-5/+8
| | | | | | | | | | | | | | | After the mutex optimizations on Mac, we did not handle the case where semaphore_wait() could return KERN_ABORTED. Under heavy contention, this happens, and when running in release mode, the assert in qmutex.cpp is not executed. The code silently allows multiple threads to continue as if it had acquired the mutex exclusively. Fix this by checking for KERN_ABORTED from semaphore_wait(), and retry the wait. We do not handle KERN_ABORTED for timed waits, simply return false and let the code doing the tryLock() handle it how it deems best.
