* QML: Warn about variables being used before their declarationUlf Hermann2021-02-111-0/+8
| | | | | | | | | | | | | | | | | | This collides with injected signal parameters. qmlcachegen cannot tell those cases apart. [ChangeLog][QML][Important Behavior Changes] QML warns about JavaScript variables being used before their declaration now. This is almost always a mistake. It is particularly dangerous in the presence of injected signal parameters because qmlcachegen cannot identify a name collision between an injected signal parameter and a variable being used before its declaration. It therefore miscompiles such code. You can turn off the deprecation warning using the "qt.qml.compiler" logging category.

* QmlCompiler: Allow for multiple extensions per objectUlf Hermann2021-02-013-0/+49
| | | | | | | | | | | | | | | | | | | Previously, the assumption was that each object could only have a single extension object. As proven by the new qqmllanguage test this is not the case. Each registered object in the type hierarchy can have its own extension. Therefore, adjust the algorithms that generate qmltypes and iterate the extension objects when analyzing them. This leads us to the realization that anonymous types can in fact meaningfully carry extensions and implement interfaces. Adapt qmltyperegistrar accordingly. For the test to compile, however, we need to realize that the class declaring interfaces needs to befriend all potential subclass's QmlInterface structs. Fix that, too. The rabbit hole went deep.

| | | | | | | | | | | | | | | | | | We don't want to pick the dependencies from the qmltypes files. Rather, parse them directly from the qmldir. Do process versions, too. Also, import explicitly given qmltypes files only once, and don't expose QML types from dependencies as actual types. Hide them behind an inaccessible prefix. For the inaccessible prefix to work, we need to import the C++ class names without the prefix. The prefix doesn't make sense for C++ names anyway. In addition, properly process version-less imports.
