* QV4String: properly detect overflow when trying to convert to an array indexGiuseppe D'Angelo2016-11-042-4/+10
| | | | | | | | | | | | | | | A wrong overflow detection caused strings like "240000000000" to pass the conversion, even though they would not fit into a uint when converted into base-10. This mis-conversion to uint then caused all sorts of side effects (broken comparisons, wrong listing of properties, and so on). So, properly fix the overflow detection by using our numeric private functions.

* Fix QML Compiler crashSimon Hausmann2016-10-251-4/+1
| | | | | | | | | | | | | | After commit 2afb54fb51091765f79548b0b057795bc3c6eb38, Primitive::undefinedValue() uses setM() to clear out all bits. Previously that code was #ifndef'ed out for the bootstrap build, but now that we can do the correct boxing in host builds (as we know the pointer size), we can re-enable setM() in bootstrap builds and fix this crash that was a Q_UNREACHABLE() assertion.

| | | | | | | | | | | | | | | | | | | | | | | | Mark QQuickItem visual children directly in QQuickItem instead of relying on the item being a (grand) child of a window. [ChangeLog][QtQuick] Fix crash with QQuickItems created via JavaScript being garbage collected sometimes when they're not assigned to a window. This may happen even in qmlscene when between the creation of the root item and the assignment to the QQuickWindow the garbage collector runs. The previous approach of a persistent in QQuickView marking the visual item hierarchy relies on the existence of a view. The only thing left to do in the view and qml window implementation is enforcing the CppOwnership policy set on the content item in QQuickWindow by ensuring the presence of the JS wrapper, replacing the persistent with a weak value. This also introduces a new internal mechanism for QObject sub-classes to provide their own V4 JS wrapper types.

* | Propagate window enter event as hover enter event in QQuickWindowEike Hein2016-09-151-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QQuickWindow currently propagates window leave events as hover leave events to its content item, but it does not propagate window enter events as corresponding hover enter events. Instead, hover enter is only triggered implicitly by mouse moves. This can cause problems when there is no mouse movement inbetween the window being entered and a subsequent button press event. A common example where this occurs is dismissing a mouse-grabbing popup window (e.g. a QMenu) by clicking outside the popup, and then clicking in the same spot that was clicked to dismiss the popup. Without this patch, hover state is not realized until movement occurs, so there may be no no visual feedback and code that needs to update state based on what is being hovered prior to handling a press event can't work correctly. This patch synthesizes a QHoverEvent and delivers it in response to QEvent::Enter, similar to how QEvent::Leave is already handled. QWidget handles this correctly via QWidget::enterEvent. The equivalent in Qt Quick is QQuickItem::hoverEnterEvent, ultimately called with the synthesized event. The patch also updates the touchmouse::hoverEnabled autotest. Due to the window enter event now being handled correctly, exitSpy2 would run up a count() of 2, as the cursor was not in a neutral position after previous test cases. The change makes sure the cursor is in a neutral position before test case activity. [ChangeLog][QQuickWindow] The relevant child item is now sent a hover event when the window receives a QEnterEvent, making sure hovering is recognized without waiting for mouse movement.

* Workaround crashes in QtQml code related to dead-store eliminationJonathan Liu2016-08-281-1/+1
| | | | | | | | | | | | | | | | | | | | | When compiled in release mode with GCC 6, QtQml may crash. This is because the C++ compiler is more aggressive about dead-store elimination in situations where a memory store to a location precedes the construction of an object at that memory location. The QV4::MemoryManager::allocate{Managed,Object} functions allocate memory and write to it before the caller does a placement new to construct an object in the same memory. The compiler considers these writes before the constructor as "dead stores" and eliminates them. The -fno-lifetime-dse compiler flag is added to disable this more aggressive dead-store eliminiation optimization. This is a temporary workaround until a proper solution is found.
