* Clean up the code handling reads and writes into typed arraysLars Knoll2018-08-251-3/+3

* Add support for disk caching of ES modulesSimon Hausmann2018-08-171-5/+9
| | | | | | | | | | | | | | | | | | Two minor fixes needed for this otherwise straight-forward change: (1) When compiling modules, use the full url for the source file of the compilation unit, as that's what we use for the relocation check when loading the cache file. (2) Record the proper source time stamp for cache invalidation. As a bonus, when importing scripts from .qml files, we now also attempt to use the cached version that we created on the fly in an effort to replace heap memory with mmap backed memory - just like we do for .qml files.

* Add support for importing ES modules in .qml filesSimon Hausmann2018-08-171-1/+23
| | | | | | | | | | | | | | | | | This is a straight-forward hook into the module implementation in QV4::ExecutionEngine. Modules are pre-compiled in the QML type loader thread. That thread keeps track of all pending loading scripts through the type loader's m_scriptCache. Once a module is compiled, it's thread-safely registered with the execution engine. Script instantiation and evaluation is done solely in the QQmlEngine's thread. ES Modules are identified in imports as well as qmldir files by the .mjs extension.

* Add initial basic support for ES6 modulesSimon Hausmann2018-08-091-0/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The entry point from the parsing perspective into modules is not QV4::Script but QV4::ExecutionEngine::compileModule. For convenience, the ESModule AST node gets a body, which is the statement list connected between the ModuleItemList items that are not import/export declarations. The QV4::Module allocates a call context where the exported variables are stored as named locals. This will also become the module namespace object. The imports in turn is an array of value pointers that point into the locals array of the context of the imported modules. The default module loading in ExecutionEngine assumes the accessibility of module urls via QFile (so local file system or resource). This is what qmljs also uses and QJSEngine as well via public API in the future. The test runner compiles the modules manually and injects them, because they need to be compiled together with the test harness code. The QML type loader will the mechanism for injection in the future for module imports from .qml files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When incubation is triggered from C++ and reaches the state of setting the initial properties (as supplied to incubateObject), we'd set engine->currentStackFrame to a CppStackFrame that provides access to the correct QML context. As we're not called from the interpreter, the v4Function pointer would be a null pointer. If during the initial property setting an exception is thrown (due to non-existent property access) and a back-trace is created, we'd end up dereferencing v4Function.
