* Add support for disk caching of ES modulesSimon Hausmann2018-08-179-14/+79
| | | | | | | | | | | | | | | | | | 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 Hausmann2018-08-1719-72/+215
| | | | | | | | | | | | | | | | | 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.

* Fix the name of anonymous generators and function declarationsSimon Hausmann2018-08-152-7/+12
| | | | | | | | | | | | | | | | | | The spec says in 14.4.12 that an anonymous generator declaration can only occur as part of the export declaration. The same applies to anonymous function declarations in 14.1.20. It is only in the default export declaration rule that we can detect that we have an anonymous declaration/generator, so that is where we implement the step of setting "default" as the function name. It is safe to use an empty string in GeneratorDeclaration_Default and FunctionDeclaration_Default because that rule is only referenced from HoistableDeclaration_Default, which in turn is only referenced from ExportDeclaration.

This patch uses the index space after the locals in the internal class for imports, so that after we've identifier the export in the local export entry table, we can use the local name to search in the internal class and find imports past the locals.

* Fix module dependency handlingSimon Hausmann2018-08-1410-47/+54
| | | | | | | | | | | | | | | | | | | | | The evaluation of a module can have side-effects by modifying the global object or objects in it. Therefore even a seemingly empty import such as import "./foo.js" needs to be listed in the module requests. It's also important that they are evaluated in the order of declaration. Therefore we collect all module requests separately - even those that don't have import variables to process. This patch also ensures that the export and import declarations are visited in the correct order, by unifying both AST nodes to be hooked into the statement list. The fact that we connect the module list items into a statement list is solely an artifact of re-using defineFunction() which takes a StatementList as body.

* QQuickTableView: remove cacheBuffer from the public APIRichard Moe Gustavsen2018-08-1013-38/+0
| | | | | | | | | | | | | | | | | | As discussed during API review, remove cacheBuffer from the public API. The cache buffer was a feature inherited from ListView to avoid loading a lot of items (and affect performance) when the user started to flick. But now that TableView has support for reusing items, the point of the cache buffer is more or less gone. At least we choose to remove it from the public API until we have better understanding if this is really needed. Note that the cacheBuffer still plays a small role internally, so we don't remove it from the implementation. We want to preload an extra row and column for reuse at start-up, since you often cannot reuse the first row and column during the first flick (they will still be visible on the screen).

* QQuickTableView: override contentWidth/Height propertiesRichard Moe Gustavsen2018-08-094-6/+117
| | | | | | | | | | | | | | | | | TableView uses contentWidth/height to report the size of the table (this will e.g make scrollbars written for Flickable work out of the box). This value is continuously calculated, and will change/improve as more columns are loaded into view. At the same time, we want to open up for the possibility that the application can set the content width explicitly, in case it knows what the exact width should be from the start. We therefore override the contentWidth/height properties from QQuickFlickable, to be able to implement this combined behavior. This also lets us lazy build the table if the application needs to know the content size early on. The latter will also fix problems related to querying the content size from Component.onCompleted.

* Add initial basic support for ES6 modulesSimon Hausmann2018-08-0930-73/+905
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix ASAN warnings about new-delete-size-mismatchSimon Hausmann2018-08-081-1/+9
| | | | | | | | | | | | | | | | | | The optimization of allocating memory for a QML type along with its declarative data in one shot works well and has worked well for many years. However ASAN complains about it, because when the delete expression is called from _anywhere_ on for example a QQuickItem, the size returned by the virtual destructor and then passed to operator delete is less than what was allocated earlier (to include the declarative data structure). Fix this by providing an operator delete for the final QQmlElement class that we _do_ allocate, which is passed along by the virtual destructor. That operator ignores the size and thus silences ASAN.
