* Port from QAtomic::load() to loadRelaxed()Giuseppe D'Angelo2019-06-201-6/+6
| | | | | | | | | | | | | | | Semi-automated, just needed ~20 manual fixes: $ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)load\(\)/$1loadRelaxed\(\)/g' -i \{\} + $ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)store\(/$1storeRelaxed\(/g' -i \{\} + It can be easily improved (e.g. for store check that there are no commas after the opening parens). The most common offender is QLibrary::load, and some code using std::atomic directly. Change-Id: I07c38a3c8ed32c924ef4999e85c7e45cf48f0f6c Reviewed-by: Marc Mutz <marc.mutz@kdab.com>

* winrt: Explicitly set main thread in QCoreApplication's constructorOliver Wolff2018-10-081-2/+33
| | | | | | | | | | | | | | | For winrt we cannot rely on the fact, that QThread::current will be called from the correct thread for the first time. The application's main entry point creates a suspended thread and starts it right afterwards. At that moment, other functionality (QLoggingRegistry for example) might have called QThread::current, which set the wrong thread as the main thread. In order to avoid this situation, the main thread is explicitly set in QCoreApplication's constructor.

* QThread: terminate on exceptions leaving run()Giuseppe D'Angelo2017-04-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Align ourselves to the Standard Library and call std::terminate if an exception leaves the thread entry point (that is, run()). On platforms using pthreads, thread cancellation needs to be taken in special consideration, since it looks like it was supported before. On Glibc, and when using C++, pthread_cancel and pthread_exit are implemented by throwing a special kind of exception that can be caught, but must always be rethrown. That exception is then used to activate the cancellation clean-up handlers. (This is non-Standard C++ behavior.) So: mimic what libstdc++'s std::thread does to support Glibc's pthread cancellation. At this time, it looks like libc++ has no support for this, and when used in combination with Glibc a thread cancellation results in a crash (also because it does not seem to terminate() when exceptions leave the thread). [ChangeLog][QtCore][QThread] An exception escaping from QThread::run() will now result in immediate and abnormal program termination. The same applies if an exception leaves a slot connected directly to the QThread::started() or QThread::finished() signals.

* Windows: stop using _beginthreadex on regular buildsThiago Macieira2016-06-021-2/+13
| | | | | | | | | | | | | | | | | | | | | | | This commit also reverts fecaa6aae83a3ffa8f1fd41c5aa8275a1bfa7c9b. The Microsoft documentation says _beginthreadex and _endthreadex are used to initialize the C/C++ runtime and are necessary when linking to libcmt(d).lib (that is, when using the -MT or -MTd options). For regular builds linking against the .dll runtime, there should be no impact. Inspection of the CRT source code which gets installed with Visual Studio or Windows SDK proves that. It's preferable to use CreateThread directly as _endthreadex will try to call FreeLibraryAndExitThread, which can cause a deadlock if we try to wait for the thread to exit from a global destructor. For -MT builds, since there can be no DLLs, it's not a problem to continue to use _beginthreadex and follow Microsoft's recommendation.

Since Qt Widgets has these macros in the static initialization of the library, we would register the Android main thread as the main thread of Qt, which would mean that the actual application object was created on a different thread than the main thread. This caused warnings to appear, and also triggered a race condition which caused widget applications to sometimes show a black screen instead of content on startup when run with the OpenGL plugin.

The task can check QThread::isInterruptionRequested() and act upon it by stopping itself. These methods are designed to replace the use of a global variable and other hacky ways to stop a task running in another thread.

* Fix race condition in QThread::setPriorityDavid Faure2013-03-231-19/+13
| | | | | | | | | | | | | The value of priority was read without the mutex locked, from within the thread. Had to extract a QThreadPrivate::setPriority method so that it can be called with the mutex already locked. So if the main thread calls setPriority while the thread is starting, it will be either be before or after the "re-set priority" code at thread startup, but at least not in the middle of it.

* Remove the QThread::terminated() signalSze Howe Koh2012-10-191-9/+1
| | | | | | | | | | | | | | | | | The signal is removed from the API; all references to it are removed from documentation; the unit test that checks for its emission is modified to listen for QThread::finished() instead. The QThreadPrivate::terminated flag is also removed, as it served no purpose other than to trigger the emission of QThread::terminated() As discussed at http://lists.qt-project.org/pipermail/development/2012-October/007216.html the signal is not guaranteed to be emitted after every termination, rendering it useless.
