* Use the QmlContext to access properties of the scope objectLars Knoll2015-08-101-8/+1
| | | | | | | | | Add some runtime methods to access properties of the scope object directly (using the QmlContext), and generate proper code to call those. Change-Id: I0b29357c9a3b9ad53ba568ec6cb763e8ecb10f21 Reviewed-by: Simon Hausmann <simon.hausmann@theqtcompany.com>
* Add ability to retrieve and use the QmlContext from our generated codeLars Knoll2015-08-101-1/+6
| | | | | | | | | | | | | | Our generated code (JIT and interpreter) should operate on the QML context to retrieve QML related things. That's better than operating on 4 different temps. So this commit introduces the QML context as a temp in the code we generate for QML. The next commits will move things over to use that context with specialized runtime methods instead of using generic subscript/get calls on the different subobjects.

| * Avoid uninitialized bytes in QV4::CompiledDataSimon Hausmann2015-05-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | When populating the QV4::CompiledData for a JS unit, we memset the malloc'ed data to zero. We should do the same when creating a unit for QML files. We do write all the fields that we use, but due to padding we may end up with bytes that are neither used nor written but still uninitialized. Consequently they should be zero'ed, otherwise serialization will write garbage. Change-Id: I0b093e4dde6789d7236247507221f4f3476ba89d Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* Clean up JS .import/.pragma directive scanningSimon Hausmann2015-01-081-246/+39
| | | | | | | | | | | There's a scanner in QQmlJS::Lexer::scanDirectives that can parse those, so let's get rid of extra parser that operates on a string. Instead this way we can do the scanning all in one shot, avoid detaching a copy of the source code string and (most importantly) bring the parser closer to the copy in Qt Creator, which uses the directives approach to extract imports and pragma.

* Initial work on gadget supportSimon Hausmann2014-12-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | Changed built-in QtQml value types to use gadgets. This is in preparation for supporting external gadgets. This replaces the mostly direct inheritance of the concrete value types with gadgets and "dynamic" inheritance through QQmlValueType being generic. Over time as some of the value types may become gadgets, we can remove the ones here. It's important that these "separate" gadgets have the same memory layout as the actual types (QPointF, etc.). Also while QQmlValueType remains practically a singleton, it's not required anymore to be one. Consequently the JS wrappers for value types keep their own instance of QQmlValueType. This allows eliminating the qobject_cast in various places that dealt with the singleton nature. This comes at a cost, making the JS wrappers slightly heavier. However that is meant to be a temporary situation and finally the value type wrapper should merely store the meta-object in addition to the data and the type.

* Fix QQmlExpression/QQmlScriptString/QQmlBinding crashesSimon Hausmann2014-10-091-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | In the QQmlScriptString we store the binding id and it is an index into the runtimeFunctions array of the compilation unit. However we don't store the compilation unit and instead in QQmlBinding and QQmlExpression try to retrieve it from the cache via the context url (we have the context after all). That turns out to be not a reliable way, as sometimes the URL might slightly differ from the originally compiled cache (qrc:/// turning to qrc:/ maybe). Consequently the type is (unnecessarily) compiled again and unfortunately not _linked_, therefore the runtime functions array is empty. Another option is that when the component was created from a QByteArray, then no entry exists in the cache in the first place. This patch addresses the problem by storing a reference to the compilation unit in the QQmlContextData. That we can safely retrieve and it'll make sure the compilation unit also stays alive. In the process of that the manual reference counting was switched over to QQmlRefCount and QQmlRefPointer for QV4::CompilationUnit.
