* Rebuild QQmlData::propertyCache if deleted by another engineDavid Edmundson2017-07-131-1/+6
| | | | | | | | | | | | | QQmlData is shared between engines, but the relevant QObjectWrapper is not. Since 749a7212e903d8e8c6f256edb1836b9449cc7fe1 when a QObjectWrapper is deleted it resets the shared QQmlData propertyCache. In most cases the propertyCache except when a property updated in an existing binding in the first engine, where it currently asserts.

* | Fix loading QML caches for qrc:/// urlsAlexander Volkov2017-06-131-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running examples/quick/window/window produces debug messages: "QML source file has moved to a different location." This is because QQmlFile::urlToLocalFileOrQrc(const QString &) overload is incompatible with QQmlFile::urlToLocalFileOrQrc(const QUrl &) when it deals with qrc:/// urls. For example it returns ":///window/window.qml" while the QUrl overload returns ":/window/window.qml". Thus the comparison of source paths in CompilationUnit::loadFromDisk() fails. Fix the incompatibility and add a test. Change-Id: I20449b8cf13d715d88860f2cd413ab39c893f3ef Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

However, this was turned into a larger problem by making more extensive use of QQmlTypeNameCache in e74a1d0b342f2c95dc3a543c8c9ec07fd52d8fe0, as it contained a lot of new types (including composite types, which previously were only in the cache if they were singletons).
