| | | | | | | | | | The non-futex implementation does not support timed locks in QBasicMutex. That is only supported in QMutex (due to the destructor).

* Make QBasicMutex be exclusively non-recursiveThiago Macieira2012-09-141-1/+5
| | | | | | | | | | | | | | | Dispatch to the recursive mutex functions from QMutex::lock, tryLock and unlock. This has the benefit that those using QBasicMutex will not go through the testing for recursive mutexes. It simplifies a little the code for those users. For the users of QMutex, the code required to perform a lock does not appear to change. Change-Id: I0ca9965e012b283c30f1fab8e9f6d9b3288c2247 Reviewed-by: Lars Knoll <lars.knoll@nokia.com>
* Mark mutex locking and unlocking functions with noexceptThiago Macieira2012-08-251-14/+18
| | | | | | | | | | | | | | | | | | | | | Unlocking a mutex can never throw an exception. That doesn't make sense and our code should make sure it can't happen. Right now, provided that the system-level functions don't throw, we don't either. Locking a mutex cannot throw on Linux because we use futexes directly. A non-recursive mutex is just a futex, whereas a recursive mutex uses a mutex (a futex) to manage a lock count. However, on other platforms, due to the freelist, there can be memory allocation, which means it might throw std::bad_alloc. Not because of the freelist itself (that uses malloc and will just crash if malloc fails) but because of Q_GLOBAL_STATIC. In 5.1, the global static will be noexcept provided the type's constructor is so too (it is, in this case).

* Optimise QMutexLocker a little: don't call relock() in the constructorThiago Macieira2012-08-061-2/+5
| | | | | | | | | | | | QMutexLocker does not support being passed already-locked mutexes, unless they are recursive mutexes. But in that case, it behaves as if the mutex weren't locked in the first place. Since that's the case, there's no point in testing the low bit to see if it's set or not. It's never going to be.

* QMutex: de-inline lock(), unlock(), and tryLock()Bradley T. Hughes2012-05-291-6/+11
| | | | | | | | | | | | | | See the discussion of this topic on the mailing list: http://lists.qt-project.org/pipermail/development/2012-May/003943.html The consensus is to not have these methods have inline code to actually acquire the lock (i.e. no atomic test-and-set or similar). QBasicMutex is unchanged, and continues to have inlined lock(), tryLock(), and unlock(). QMutexLocker has been changed to always call QMutex::lock() (even though the constructor takes a QBasicMutex parameter).
