* Don't queue events in QFutureWatcher when pause is requestedSona Kurazyan2020-05-272-26/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When QFutureWatcher (or QFutureInterface) is paused, it doesn't mean that it will take effect immediately: the pending tasks may still be in progress and keep reporting results. At the moment QFutureWatcher will queue those events and report only with the next resume. This behavior is wrong, QFutureWatcher should not decide when to report events, the sender should decide when is the right time. There's no benefit in reporting already happened events with delay. Because of this, even the pause event itself was being reported after resume. Fixed the behavior by removing the logic of queueing events when the state is set to "paused". It seems unlikely that the users of QFutureWatcher rely on reporting events with delay. [ChangeLog][Important Behavior Changes][QtCore] QFutureWatcher will not immediately stop delivering progress and result ready signals when the future is paused. At the moment of pausing there may be still computations that are in progress and cannot be stopped. Signals for such computations will be still delivered after pause, instead of being postponed and reported only after next resume.

* | QFuture - add ability to move results from QFutureTimur Pocheptsov2020-03-316-25/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QFuture's original design pre-dates C++11 and its introduction of move semantics. QFuture is documented as requiring copy-constructible classes and uses copy operations for results (which in Qt's universe in general is relatively cheap, due to the use of COW/data sharing). QFuture::result(), QFuture::results(), QFuture::resultAt() return copies. Now that the year is 2020, it makes some sense to add support for move semantics and, in particular, move-only types, like std::unique_ptr (that cannot be obtained from QFuture using result etc.). Taking a result or results from a QFuture renders it invalid. This patch adds QFuture<T>::takeResults(), takeResult() and isValid(). 'Taking' functions are 'enabled_if' for non-void types only to improve the compiler's diagnostic (which would otherwise spit some semi-articulate diagnostic). As a bonus a bug was found in the pre-existing code (after initially copy and pasted into the new function) - the one where we incorrectly report ready results in (rather obscure) filter mode.

Continuations can use the following execution policies: * QtFuture::Launch::Sync - the continuation will be launched in the same thread in which the parent has been executing. * QtFuture::Launch::Async - the continuation will be launched in a new thread. * QtFuture::Launch::Inherit - the continuation will inherit the launch policy of the parent, or its thread pool (if it was using a custom one). * Additionally then() also accepts a custom QThreadPool* instance. Note, that if the parent future gets canceled, its continuation(s) will be also canceled. If the parent throws an exception, it will be propagated to the continuation's future, unless it is caught inside the continuation (if it has a QFuture arg). Some example usages: QFuture<int> future = ...; future.then([](int res1){ ... }).then([](int res2){ ... })... QFuture<int> future = ...; future.then([](QFuture<int> fut1){ /* do something with fut1 */ })... In the examples above all continuations will run in the same thread as future. QFuture<int> future = ...; future.then(QtFuture::Launch::Async, [](int res1){ ... }) .then([](int res2){ ... }).. In this example the continuations will run in a new thread (but on the same one). QThreadPool pool; QFuture<int> future = ...; future.then(&pool, [](int res1){ ... }) .then([](int res2){ ... }).. In this example the continuations will run in the given thread pool. [ChangeLog][QtCore] Added support for attaching continuations to QFuture.

Even if we don't know the assembler for an architecture, taking the address of the thread_local variable is still faster. As QThread::currentThreadId() is documented to be used internally and not meant for application code, we don't have to care about what exact value we return. Internally, we use it only to compare thread IDs for equality, which this implementation is sufficient for, even if a thread ID is re-used when one of the threads terminate and a new thread starts (since the other thread is still executing code). Besides, pthread_self documents [0] that a thread ID may be reused, and that the returned pthread_t cannot be portably compared using operator==(); using pthread_equal would require adding a Qt thread-ID type that implements this correctly, and would make things even slower.
