* | 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.

* | Add support for attaching continuations to QFutureSona Kurazyan2020-03-057-7/+645

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.

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.

On Integrity, it's a class that wraps QWaitCondition to provide the interface of std::condition_variable. This allows the use of std::condition_variable across Qt without running into the Integrity issue. Once we can depend on an more modern Integrity toolchain, removing QtPrivate::condition_variable is a simple mechanical change: s/QtPrivate::condition_variable/std::condition_variable/g; s/QtPrivate::mutex/std::mutex/g; Task-number: QTBUG-78450 Change-Id: I293a99d1cdc48691817b926aa51ecd84556e5e90 Reviewed-by: Mårten Nordheim <marten.nordheim@qt.io> Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

The _any variant works with any mutex type, but requires a native mutex for the native condition variable. So, QWaitCondition and std::condition_variable_any both require two different mutexes: the one the user passes in, and an internal one. std::condition_variable, however, only works with std::mutex, and since both are backed by the native API, condition_variable can use the mutex passed in by the user instead of having to use an internal one. So, port from 2 × QWaitCondition + QMutex (2 × native cond + 2 × native mutex + Qt mutex) to std::condition_variable + std::mutex (2 × native cond + native mutex), shaving the overhead of two additional mutexes (one Qt, one native) as well as the memory allocation performed by QWaitCondition (for its Private).
