* AreArgumentsCompatible: Replace a derived struct with template aliasThiago Macieira2017-05-051-1/+1
| | | | | | | | | | | | | There's no need to derive. This fixes the build with MSVC 2017 under /permissive-. I don't know what was wrong (ICC, Clang and GCC don't complain), but it must be related to "Lookup members in dependent base" in [1].

* QCFSocketNotifier: fix registering a source in the run loopAlex Trotsenko2017-05-031-2/+11
| | | | | | | | | | | | | | Even if a callback type is not automatically re-enabled, callbacks are implicitly enabled when the source has been added to the run loop. In this case, calling CFSocketEnableCallBacks() could produce an extra notification if there is a pending event in the queue. The bug is quite unstable and completely depends on the internal OS delays. So, it can't be tested inside Qt.

* Improve suppression of spurious socket notifications under WindowsAlex Trotsenko2017-05-032-17/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | There were still two cases where spurious notifications would be possible: - user calls hasPendingDatagrams()/pendingDatagramSize() on UDP socket somewhere outside the slot connected to readyRead() signal (::WSARecvFrom posts FD_READ notification, even if a notification for incoming datagram already exists in the message queue); - a socket was registered to receive several types of event and WM_QT_ACTIVATENOTIFIERS message is located between the different events for this socket in the queue. Provided patch ensures that the message queue is synchronized with the Qt event processing mechanism and adds a way to detect spurious notifications inside the window procedure.

* do not wrap QAbstractEventDispatcher::flush with QT_DEPRECATED_SINCEGatis Paeglis2017-04-281-3/+1
| | | | | | | | | | | | | | | | | | | ... as this would require us to remove usage of QAbstractEventDispatcher::flush from Qt source code as well. We can not do this already in Qt 5.9 as there are few event dispatchers in Qt that actually do override the ::flush (with non empty bodies).

In Qt5 this function somehow has been repurposed (inconsistently) to do what QCoreApplication::sendPostedEvents already does: QAbstractEventDispatcher::flush() = 0; => QCocoaEventDispatcher::flush() {} => QEventDispatcherCoreFoundation::flush() {} => QIOSEventDispatcher (does not override ::flush()) => QEventDispatcherGlib::flush() {} => QPAEventDispatcherGlib (does not override ::flush()) => QEventDispatcherUNIX::flush() {} => QUnixEventDispatcherQPA (when QT_NO_GLIB=true) ::flush() { if (qApp) qApp->sendPostedEvents(); }) ==> QAndroidEventDispatcher (does not override ::flush()) => QEventDispatcherWin32::flush() {} => QOffscreenEventDispatcher::flush() { if (qApp) qApp->sendPostedEvents(); QEventDispatcherWin32::flush(); } => QWindowsGuiEventDispatcher (does not override ::flush()) => QWindowsDirect2DEventDispatcher (does not override ::flush()) => QEventDispatcherWinRT::flush() {} => QOffscreenEventDispatcher::flush() { if (qApp) qApp->sendPostedEvents(); QEventDispatcherWinRT::flush(); } => QWinRTEventDispatcher (qminimaleglintegration.cpp) (does not override ::flush()) => QWinRTEventDispatcher (qwinrteventdispatcher.h) (does not override ::flush()) Whatever this function was doing on macOS in Qt3 and Qt4 also has been dropped in Qt5. It appears that the other event dispatchers in Qt5 that have overrides for flush() have simply copy-pasted this logic. Clearly the documentation of QCoreApplication::flush() is outdated and has nothing to do with the actual implementation in Qt5. This function is rarely used in Qt5 sources. It should be safe to remove the calls to QCoreApplication::flush() from Qt source code, as this function has been doing nothing on most platforms anyways. Repurposing it even broke handling of posted events (see QTBUG-48717). [ChangeLog][QtCore][Event loop] QCoreApplication::flush() is now deprecated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some compilers are known to complain about this with a warning. GCC complains about const on return values on -Wignored-qualifiers (enabled at -Wextra), so it's not too much of a jump to assume that others do too. Besides, this is not Qt Library API policy. As maintainer for QtCore, I'm exercising my prerrogative in specifying certain unspecified parts of the coding style, like I've done for constructor initializer lists. Since all the classes involved are exported (including QVector, through derived classes), we can't remove the qualifier until Qt 6, since there are compilers known to encode the qualifier in the mangled name (suncc). I'm not introducing #ifdef to silence unknown compilers unless we get an actual complaint.

This commit brings it back but makes the array a compile-time constant string offset table. The array is created by way of a set of C++11 constexpr functions, so we require that compiler feature. I've tested that MSVC 2015 does support it as well as the ICC 17 when masquerading as MSVC 2015, so I've enabled for that too. The only compiler left out is MSVC 2013. If we didn't need to support MSVC 2015, this could have been written more simply with C++14 relaxed constexpr. This also adds unit tests to confirm that QMetaType::typeName() does return null when we said it would. We're testing QMetaType::User-1 (which we'll likely never use) and QMetaType::LastWidgetsType-1 to select something inside the range of the built-in types.

* | make TabletMove hover events conditional on QWidget::tabletTrackingShawn Rutledge2017-02-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the tabletTracking property in the same way that mouseTracking already existed: there is a WA_TabletTracking attribute, and a TabletTrackingChange event to notify when it changes. So for widget applications it's an opt-in feature. QtQuick applications don't yet make use of tablet events, but when they do in the future, we don't yet have a mechanism to turn the move events off; it remains to be seen whether that will be necessary. [ChangeLog][QtWidget] QWidget now has a tabletTracking property, analogous to mouseTracking, which will enable TabletMove events while the stylus is hovering, even if no button is pressed. This allows applications to show feedback based on the other tablet event properties such as rotation and tilt.

* | Fix a race condition between QObject::connect and qRegisterMetaTypeOlivier Goffart2017-02-221-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QObject::connect will extract the QArgumentType for first the signal, then the slot. The QArgumentType with a string constructor will query the metatype system to get the meta type id. But it might happen that between the extraction of the signal's argument and the slot's argument, qRegisterMetaType was called in another thread. For this reason, it's possible that one QArgumentType has a type id while the other does not. For this reason, we should fall back to compare the string if any of the argument's type is 0.

A default-constructed static QBasicAtomicInt at function scope will be dynamically initialized. It will still be zero-initialized, but at least GCC adds guard variables for such objects. When using aggregate initialization, the guard disappears. Amends 265db5ad9bda9c984393c1e95fd27dcc4633ed1c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was unnecessary, since we only cached the static types, which are all generated by the macro anyway. The way it was implemented, this produced data races that are strictly-speaking UB, even if all the threads were writing the same values to the same data locations. This commit changes a little the code to simplify, since we're changing those lines anyway.

| * QJNIHelper: fix a potential race in sendRequestPermissionsResult()Marc Mutz2017-02-151-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code obtained an iterator into a QHash under mutex protection, then dropped the lock, dereferenced the iterator several times and only retook the lock to erase the element from the QHash. This is very smelly. QHash provides no official iterator validity guarantees, and the container isn't const, either (which would imply thread-safety). In particular, the dereference into the container outside the critical section is cause for concerns. Simplify the code, removing any doubts about its race-freedom, by taking the payload item out of the hash before dropping the lock, and using only the local strong reference in the remainder of the function. The only other references to g_pendingPermissionRequests are insertions with unique-by-construction keys in QtAndroidPrivate's requestPermissions(), so there was no reason to keep the item in the hash for the whole duration of the sendRequestPermissionsResult() call.
