* Remove qatomic_mips.h: the 3-operand testAndSet is brokenThiago Macieira2015-11-051-2/+0
| | | | | | | | | | | | | | | | | The "previous" value is always 1 when the compare-and-swap succeeded, instead of the previous value. Instead of fixing this, let's just remove this file a bit earlier than the rest. All of them will be removed in Qt 5.7 anyway, so let's leave MIPS atomics to the compiler.

* Free the QFreeList object allocated memory on exitjian liang2015-09-221-4/+11
| | | | | | | | | | | | | This memory allocation was introduced in 314c83c0c2f91532654f869b7dc6af1b7e8538da. With a compiler without thread safe statics support mutex.cpp use a function named freelist() to create the global QFreeList object. it will be created when the first time it was accessed, but will never be released. This patch use Q_DESTRUCTOR_FUNCTION to delete this object. Task-number: QTBUG-48359 Change-Id: I4e4716930930aa98630101a1f96de6a7672af9cb Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

| | | | | | | | | | | | | | This reverts commit 666486b3efec871301b82244ec661e1eaa6cca9c, which removed the QHash that protected against reader recursion deadlocks. Without this hash, a reader will block on d->readerWait.wait() until the writer finishes its task. However, the writer never starts because there's a reader that hasn't released the lock. That's a deadlock.

| * Android: fix timed QWaitCondition::wait() on Android >= 5.0.Yoann Lopes2015-02-171-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | wait() was always returning immediately, regardless of the timeout value, due to a timespec comparison from different clock types. On Android 5.0, qt_gettime() uses the monotonic clock but the wait condition was using the real time clock. __pthread_cond_timedwait_relative() is not exported anymore in Android 5.0, we therefore fall back to pthread_cond_timedwait(). Since the monotonic clock is now available, qt_gettime returns a time based on it. The wait condition consequently needs to use the monotonic clock.

As Herb Sutter writes in http://www.drdobbs.com/parallel/use-thread-pools-correctly-keep-tasks-sh/216500409 and the Qt Training Material stresses, tasks you schedule on a (global) thread pool should be non-blocking, which currently rules out using any of the QtConcurrent functions for, say, file I/O. Nonetheless it's often convenient to have thread pools also for file I/O, as the thumbnail viewer exercise in the Qt Training Material shows. In this case, you'd use a dedicated thead pool, leaving the global thread pool for CPU-bound tasks. Yet, none of the QtConcurrent functions allow to pick the QThreadPool instance on which to schedule the work created with them. This patch prepares for them to do so. This is the first part of the forward-port of https://qt.gitorious.org/qt/qt/merge_requests/1281. Implement by using a new QThreadPool* member that defaults to nullptr, and adding setThreadPool to set this member, then using it in lieu of QThreadPool::globalInstance() everywhere. I chose to leave m_pool == nullptr to mean globalInstance() to avoid creating the global instance whenever a QFuture is created, even if the future represents the result of a calculation not run on the global thread pool. [ChangeLog][QtCore][QFuture] Can now be used with any QThreadPool, not just globalInstance().

* | winrt: Use native threadingAndrew Knight2014-06-254-154/+479
|/ | | | | | | | | | | | | | | | | Instead of using std::thread, use the WinRT ThreadPool to manage threads. This allows for setting the scheduling priority, and provides a path to enable XAML integration (which requires Qt run on a background thread). QThread::terminate() is still unsupported, and only the winmain thread can be adopted due to the behavior of the thread pool when creating tasks from the GUI thread. The associated tests are now skipped, and all other QThread tests pass.

* WinRT: Don't use the native thread handle for waitingAndrew Knight2014-04-161-15/+6
| | | | | | | | | | | There is no guarantee that the handle from std::thread will be valid when a wait is made. Instead, simply use an elapsed timer and check if the thread is finished. This prevents an exception from being thrown when a bad handle is encountered.

* WinRT: Use native wait methods instead of std::thread's sleep_forAndrew Knight2014-03-061-4/+4
| | | | | | | | | sleep_for appears to be unreliable (resulting in infinite waits) when used in a thread which is also using native waiting methods. This is also a step in the direction of eliminating std::thread's usage in WinRT. Change-Id: I58bc4bf9ada25de247849333ef925964676b7239 Reviewed-by: Oliver Wolff <oliver.wolff@digia.com>
