* Replace QFlagPointer with QTaggedPointerSimon Hausmann2020-04-031-9/+22
| | | | | | | | 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>

* QML: Unify property reads/writes and use accessorsErik Verbruggen2016-07-251-1/+1
| | | | | | | | | Pass property reads/writes through utility functions in QQmlProperty, which in turn will try to use accessors when available (and no interceptors have to be called). Change-Id: I60ecfc202b6024bfe4a33206a46299787b152546 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* QML: Introduce write accessors to QQmlAccessorsErik Verbruggen2016-07-081-0/+9
| | | | | | | | | | | | | | | | Same idea as the read accessors, but with a slight difference: the property setters do emit signals, so we can't do a direct property write and have to call the setter. However, it does circumvent the meta-calls. There is one gotcha: if a property is intercepted (e.g. by a Behavior), we still have to do the meta-call in order to dispatch the write to the interceptor. According to valgrind, this saves 138 instructions on x86 for every "accessible" property write.

* Make bindings refcountedLars Knoll2015-06-101-27/+19
| | | | | | | | | | | Refcounting our bindings greatly simplifies our memory management of the objects and ensures we safely clean them all up. In addition, it allows us to remove the m_mePtr and weak reference handling from QQmlAbstractBinding as we can safely handle this through the same mechanism.

* Fix error reporting timingSimon Hausmann2013-09-121-3/+1
| | | | | | | | | | | | | Errors for example in signal declarations are usually reported in the loader thread, during property cache construction. This patch separates out the property cache population into QQmlPropertyCacheCreator, runs it from the loader thread and reduces the QQmlObjectCreator to merely set the properties/bindings/ functions on the object. This also enables location tracking for signal declarations and their error reporting. Change-Id: Ief1ffbb3113f8279a50d1a12dab8dbe096702a60 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Beginning of a new qml parserSimon Hausmann2013-09-081-0/+5
| | | | | | | | | | | | | | The goal is to parse QML and JavaScript binding expressions/functions in one go and generate data structures that allow for the parsing to happen in a thread and the instantiation of the object tree in another thread, just reading from the generated data structures. This will replace qqmlcompiler and the VME. This new way of loading QML is currently hidden behind the QML_NEW_COMPILER=1 environment variable. There's lots of work left to fill in the gaps in object construction, Component support, Component.onComplete, error messages, etc. etc. Change-Id: I5e40643cff169f469f0b6ce151584ffee5ca5e90 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* Evaluate bindings more intelligently during constructionAaron Kennedy2012-08-291-0/+2
| | | | | | | | | | | | | | | | | Instead of just evaluating bindings in a fixed order, and possibly having to evaluate a single binding multiple times, prior to reading a property, we check if there are any bindings "pending" on it and evaluate them then. A pending binding is one that has been assigned to the property, but not yet evaluated. To minimize side effects we only do this for "safe" bindings. A safe binding is one that has no side effects, which we currently define as not calling functions or otherwise assigning values during its evaluation. This isn't an entirely foolproof way to ensure that the evaluation has no side effects, but it should be good enough.
