* Fix lookups of properties in QML singletonsSimon Hausmann2019-05-211-1/+0
| | | | | | | | | | | | An unqualified name that points to a QML singleton will evaluate to a QQmlTypeWrapper JS object. A member lookup in such an object is not guaranteed to always produce the same property. The property cache check may protect us from that, but we must still retrieve the QObject singleton for every lookup.

* Remove dead compile time QML context/scope property and id object codeSimon Hausmann2019-03-201-24/+4
| | | | | | | | | | | After enabling lookups in QML files, we can remove all the code that tries to deal with (type) compile time detection of access to id objects and properties of the scope/context object. This also allows removing quite a bit of run-time code paths and even byte code instructions.

* Enable lookups in QMLSimon Hausmann2019-03-191-37/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | The main feature that needs to be implemented in order to enable lookups in QML files is to respect that the QObject wrapper has its own storage layer (meta-object properties). Lookups need to be able to index those when the base is a QObject. This is done by caching the property data and guarding the validity by comparing property cache pointers. The same lookup logic is also implemented for value type wrappers. OVerall there's more that can be done with lookups in meta-objects, for constant properties for example. For "global" lookups we have a safeguard in place that generates a LoadName instruction for property access that should end up in the qml context wrapper. So no changes are needed here at first, but the lookup in the QML context can be optimized in the future. The way of storing the property cache in the lookup itself trades ugliness on destruction against the creation of less internal classes. Another option would be to store the property cache in the internal class and let QObjectWrapper always transition via the property cache.

| | | | | | | | | | | Such WeakValues are kept alive until the respective QObject is deleted. Therefore they are quite expensive. In this case we don't actually need a copy as on retrieval we only want a ReturnValue and on inserting we just want to replace the value in the map.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling Qt.binding() on a bound function object is a valid use case and used to work until Qt 5.8. The problem was that we optimized the code in QQmlBinding and QQmlJavascriptExpression to directly work on a QV4::Function, so this wouldn't work anymore. To fix this make sure recursive calls to Function.bind() are unrolled (so that the BoundFunction's target is never a bound function itself), then add the bound function as an optional member to the QQmlBinding and use it's bound arguments if present.
