* Replace QFlagPointer with QTaggedPointerSimon Hausmann2020-04-031-152/+0
| | | | | | | | The latter has the advantage of allowing the use of a real type for the tag, instead of the generic flag/flag2 boolean accessors. Change-Id: Icc9e854ce4af3eb5808a4bed45aa22f377e223da Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>

* Remove bindings that have no dependenciesSimon Hausmann2018-05-161-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the initial enabling of a binding we can quickly determine if there is a chance whether this binding will be re-evaluated again in the future as a consequence of dependency changes (properties or translations). If that is not the case, then we can save memory by removing that binding again. One implementation consequence of this change is that such constant bindings used with the "when" property of states require a proper reference count increase, which was previously implicit through the binding association with the target object. In tst_qqmlecmascript a test that verifies that we don't create run-time bindings for assignments of literal "null" to QObject pointer properties now also covers the more complex case where we don't know the property at parse time. We still evaluate the binding once though and perform one property assignment. Similarly on the QtQuick Designer Support API test side a binding such as x: Math.max(0, 200) will not create a persistent binding anymore and needs a tweak to remain. On a large scale application this optimization saved up to 5% of all bindings on start-up (~9000 of ~180000). On Linux x86-64 one binding is approximately 144 bytes, so the savings are in the range of ~1.2 MB of heap, as well as reduced fragmentation.

* Restrict v8 property lookup to the execution contextMatthew Vogt2012-08-271-0/+8
| | | | | | | | | | | | | When resolving property names, only properties known to the current context of execution should be available. If a property name has been overriden by a component extension, code executing in the context of the base component should resolve the property name to the property available inside the base component or its bases.
