* Remove old compiler and VMESimon Hausmann2014-03-071-102/+0
| | | | | | | | | | | | This removes the bulk of the code. A few smaller cleanups remain, to be done in smaller changes as they move code around. Additionally the "optimize" option of qqmlbundle was removed. It called QQmlScript::Parser::preparseData, which however was not implemented and always returned an empty QByteArray. Therefore "optimize" would not do anything and the class is gone now :) Change-Id: I0c265e756704cb53c5250be1f69e4a3e1b6e64d5 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* [new compiler] Fix invalid memory reads when JS closures outlive QML typesSimon Hausmann2014-03-051-1/+2
| | | | | | | | | | | | | If QQmlCompiledData gets destroyed while somebody still has refcount on the QV4::CompiledData::CompilationUnit, then unit's _data_ would be freed already by ~QQmlCompiledData. Given that compilationUnit->data is pointing to the same malloc'ed address as QQmlCompiledData::qmlUnit, we can just let the CompilationUnit always own the data. Fixes tst_qquickloader and makes it possible to run the qquickcomponent tests. Change-Id: Ie3f3e5335139236d7c2524a327665bda0a9cc847 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* [new compiler] Fix parser status and created bindings allocationSimon Hausmann2014-02-071-1/+1
| | | | | | | | | | | | | | | Pre-calculate the amount of space we need for binding and parser status callbacks at compile time and therefore use a much simpler data structure (vector) to store the points to the bindings and callbacks. They need to be stored because during object construction and binding enabling phase, it may happen that they get destroyed and thus their m_mePtr pointing into the array gets deleted. The contiguous vector will also make it possible to interrupt the completion phase. Change-Id: Ic7c985bb8325ab355112e30e9d33d6ae4e7476d1 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* [new compiler] Fix refcounting leaks with property cachesSimon Hausmann2014-01-201-5/+7
| | | | | | | | | | | The TypeReference is not copy-safe, as it holds refcounted property cache pointers. For the new compiler code path, don't copy them but keep pointers to TypeReference objects around. Also make sure to ref the root property cache correctly and avoid the unnecessary addref for the property cache when creating new vme meta objects (initial refcount is 1).

* Fix dynamic properties in QQmlPropertyMap not always being visible in QMLSimon Hausmann2013-12-051-0/+22
| | | | | | | | | | | | | | | | | | | | | | | QQmlPropertyMap is a fully dynamic class that can add properties at any point in time. In order for these properties to be visible inside QML, we must disable the property cache (instead of trying to unsuccessfully re-fresh it). What happened in this particular case is that the QQmlPropertyMap derived type was instantiated and the VME instruction for creating it would also assign the property cache the compiler determined. There's no way for QQmlPropertyMap itself to access this property cache instance (stored in output->types[id].typePropertyCache) or invalidate it, so instead don't use the compiler's property cache when instantiating the type. This patch also disallows the adding properties to QQmlPropertyMap when it is used as base type for a new QML type, as we cannot provide the derived type to the QQmlPropertyMap constructor - this is only possible in C++.

* Compile binding expressions in the QQmlCompilerSimon Hausmann2013-10-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | This is done by re-using the JS code generator from the new compiler. A few bugs were fixed on the way: * The index into the compiledData->runtimeFunctions array is not the same as the function index when they are collected (from the AST), as for example binding expressions may create extra V4IR::Function objects that break the 1:1 mapping. Therefore the JS code gen will return a mapping from incoming function index to V4IR::Module::Function (and thus runtimeFunction) * Binding expressions in the old backend get usually unpacked from their ExpressionStatement node. The reference to that node is lost, and instead of trying to preserve it, we simply synthesize it again. This won't be necessary anymore with the new compiler in the future. * Commit 1c29d63d6045cf9d58cbc0f850de8fa50bf75d09 ensured to always look up locals by name, and so we have to do the same when initializing the closures of nested functions inside binding expressions (in qv4codegen.cpp) * Had to change the Qml debugger service auto-test, which does toString() on a function that is now compiled. Even if we implemented FunctionPrototype::toString() to do what v8 does by extracting the string from the file, it wouldn't help in this test, because it feeds the input from a string instead of a file. * In tst_parserstress we now end up compiling all JS code, which previously was only parsed. This triggers some bugs in the SSA handling. Those tests are skipped and tracked in QTBUG-34047 Change-Id: I44df51085510da0fd3d99eb5f1c7d4d17bcffdcf Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* [new compiler] Initial support for group propertiesSimon Hausmann2013-09-201-1/+2
| | | | | | | | | | | | | | | | | | | This implements support for "font.pixelSize: 24" for example. The representation in the compile data structure is so that font.pixelSize is short-hand for font { pixelSize: 24 } which means that inside the braces is a complete object initializer. For that initializer we create a dedicated CompiledData::Object, which however has its type name empty. When populating the outer instance then, the "font" property is read as QQmlValueType (a QObject) and instead of creating a new QObject we use that value type as instance to run the rest of the QML object initializer (everything in braces).

* Beginning of a new qml parserSimon Hausmann2013-09-081-1/+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>

| * Partial fix for deferred properties when combined with componentsAlan Alpert2013-05-221-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current deferred properties implementation did not store context or compiled data pointers correctly. Those pointers are now stored when the defer is reached, so as to avoid confusion (confusion leads to asserts or crashes). Does not extend the deferred property support to allow multiple deferred blocks per item. This now prints and error and the side effect is only that one of the deferred blocks is lost. This use case is sufficiently rare that it may not be worth the cost.
