* QtConcurrent: mark as security-significantIvan Solovev2025-05-281-0/+1
| | | | | | | | | | | | | | | | | The QtConcurrent module applies user-provided map-, filter-, and reduce- functions (or their combinations) to user-provided data. It does not make any assumptions about the provided functions and data, apart from input/return type validation. It also does not parse the provided data and does not have any way to sanitize it. Mark all the source and header files in the module with the default security-significant score to confirm that the code was reviewed.

* Replace usages of Q_CLANG_QDOC with Q_QDOCLuca Di Sera2022-10-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | To allow the user to customize the C++ code that QDoc sees, so as to be able to work-around some limitations on QDoc itself, QDoc defines two symbols: Q_QDOC and Q_CLANG_QDOC, both of which are "true" during an entire execution of QDoc. At a certain point in time, QDoc allowed the user the choice between a custom C++ parser and a Clang based one. The Q_QDOC symbol would always be defined while the Q_CLANG_QDOC symbol would be defined only when the Clang based parser was chosen. In more recent times, QDoc always uses a Clang based parser, such that both Q_CLANG_QDOC and Q_QDOC are always defined, making them equivalent. To avoid using different symbols, and the possible confusion and fragmentation that derives from it, all usages of Q_CLANG_QDOC are now replaced by the equivalent usages of Q_QDOC.

* Remove the dead code for blocking methods from QtConcurrentSona Kurazyan2021-06-141-33/+0
| | | | | | | | | | | | | | After 79fd1cb2c631b6084bf10874205d27f5b53c907a the methods for running QtConcurrent algorithms in the blocking mode aren't used anymore. Since ThreadEngineBase and ThreadEngineStarter classes aren't meant to be used externally, it should be fine to remove startBlocking() methods now. Removed the unused code and adjusted the tests accordingly.

* Store std::exception_ptr in QUnhandledExceptionSona Kurazyan2020-10-261-2/+2
| | | | | | | | | | | | | | | | For historical reasons Qt Concurrent reports QUnhandledException in case if an exception that is not derived from QException is thrown from a worker thread. Changing this behavior may not be a good idea, since the existing user code may rely on it. Changed QUnhandledException to wrap the std::exception_ptr to the actual exception, so that the users can obtain the information about the thrown exception if needed. [ChangeLog][QtCore][QUnhandledException] Improved QUnhandledException to store the std::exception_ptr to the actual exception thrown from a QtCocnurrent worker thread.

* Deprecate the pause-related APIs of QFuture* classesSona Kurazyan2020-06-041-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Deprecated the pause-related APIs of QFuture* classes and added alternatives having "suspend" in the name instead. With 2f15927f01ceef0aca490746302a5ea57ea9441c new isSuspended()/suspended() APIs have been added to QFuture* classes for checking if pause/suspension is still in progress or it already took effect. To keep the naming more consistent, renamed: - setPaused() -> setSuspended() - pause() -> suspend() - togglePaused() -> toggleSuspended() - QFutureWatcher::paused() -> QFutureWatcher::suspending() Note that QFuture*::isPaused() now corresponds to (isSuspending() || isSuspended()). [ChangeLog][Deprecation Notice] Deprecated pause-related APIs of QFuture and QFutureWatcher. Added alternatives having "suspend" in the name instead.

* Add a way of notifying QFutureWatcher when pause is in effectSona Kurazyan2020-05-291-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | Because setting QFutureInterface to paused state does not mean that the computations that are already in progress will stop immediately, it may be useful to get notified when pause actually takes effect. Introduced the QFutureWatcher::suspended() signal, to be emitted when there are no more computations in progress, and no more result ready or progress reporting signals will be emitted, i.e. when pause took effect. Added {QFuture, QFutureWatcher}::isSuspended() methods for checking if pause took effect. QtConcurrent will now to send QFutureCallOutEvent::Suspended event when the state is paused and there are no more active threads. [ChangeLog][QtCore][QFutureWatcher] Added a new QFutureWatcher::suspended() signal, to be emitted when pause took effect, meaning that there are no more computations in progress. Added {QFuture, QFutureWatcher}::isSuspended() methods for checking if pause took effect.

* doc: Fix all qdoc errors in QtConcurrentMartin Smith2017-12-081-1/+1
| | | | | | | | | | | | | These errors resulted from the improved parsing provided by clang, which required rethinking which elements of the QtConcurrent API should be visible to clangqdoc. The basic problem is that clang must see declarations for all types used by a type, or else it either gets lost and fails to parse a type correctly, or it simply refuses to include the type in its AST.
