* Shortcut conversions of common data typesLars Knoll2020-11-271-0/+59
| | | | | | | | | | | When returning the result of bindings, shortcut the conversion of common data types and do not go through QVariant. Removes ~20% of the overhead in the evaluation of simple bindings of types bool, int, double, float and QString.

* Remove compatibility shim from qmlinfo.{cpp|h}Ulf Hermann2020-11-191-1/+1
| | | | | | | | | | | | We don't need to handle symbol clashes with QtQuick1 anymore. [ChangeLog][QtQml] The functions qmlDebug, qmlInfo, and qmlWarning are no longer available in the QtQml namespace. Use their counterparts in the global namespace.

* QQmlPropertyBinding: detect binding loopsFabian Kosmale2020-08-121-0/+14
| | | | | | | | | | | | | | Calling markDirtyAndNotifyObservers bypasses the currently existing mechanism in QProperty to detect binding loops. Moreover, simply changing updating from private to protected and setting it to true does not help us here: That would trigger a binding loop warning every time the static callback of a QNotifiedProperty acesses its current value. Thus, we add another bool to detect expressionChanged loops. To reduce memory usage, we store it as a second flag in m_error (from QQmlJavaScriptExpression).

* Fix QQmlPropertyBinding::evaluateFabian Kosmale2020-06-151-1/+6
| | | | | | | | | | | | When a class is in a semi-deleted state (QQmlData::wasDeletet returns true, but the QQmlElement has not been removed yet), we can still end up calling evaluate under some circumstance. This can be observed in qqc2's tests, for instance tst_palette. In those cases either ctxt or ctxt->engine() might be nullptr. We handle this by returning an error; as the object is about to be gone, the result does not matter anyway.

* Update dependencies.yaml and adapt to API changes in qtbaseSimon Hausmann2020-04-221-15/+6
| | | | | | | | | | | | | | | | The evaluation callback does not have to perform the comparison anymore and the shared pointer of the private is not used in the API anymore. Also, the versionFunctions() has been moved out of QOpenGLContext and renamed QOpenGLVersionFunctionsFactory::get(). QHash doesn't keep iterators stable under erase(), so clean up the code relying on it, and avoid an intermediate QList at the same time.

| | | | | | | | | | When the ahead-of-time built binding returns the same type as the QProperty, then we can connect them directly with a small shim and pass through the context and scope objects.

* Add support for binding directly to QProperty instancesSimon Hausmann2020-03-301-0/+101
Avoid going through externally managed bindings and instead allocate a more lightweight property binding. It's basically a QQmlJavaScriptExpression and one pointer plus the overhead of QPropertyBindingPrivate.
