* Cleanups in Value/PrimitiveLars Knoll2018-09-171-3/+3
| | | | | | | | | | | | Get rid of Primitive and move the corresponding methods directly into Value. Mark many methods in Value as constexpr and turn Value into a POD type again. Keep Primitive as a pure alias to Value for source compatibility of other modules that might be using it.

Also, replaced cases where 0 was passed as Qt::KeyboardModifiers with Qt::NoModifier (clang-tidy replaced them with nullptr, which waas wrong, so it was just as well to make the tests more readable rather than to revert those lines).

* Fix conversion of QByteArray back to String in JavaScriptSimon Hausmann2016-08-301-0/+10
| | | | | | | | | | | | | | | Commit 3b7e2a69f7eb8597c807de39b4de39721e9e2bd2 changed behavior so that QByteArray is converted to the JS ArrayBuffer type, which is a better fit than QVariant. However ArrayBuffer does not have a toString method in the spec, and therefore any previous implicit toString conversion such as when passing to JSON.parse() would fail. To restore compatibility this patch adds a non-spec toString() that performs an UTF-8 conversion, as it was done previously through QVariant's toString.

* V4: Pass scope around as parameters inside the runtime.Erik Verbruggen2016-06-221-12/+18
| | | | | | | | | | | | | | | | The implementation of many (or all) runtime functions consist of first creating a QV4::Scope, which saves and restores the JS stack pointer. It also prevents tail-calls because of that restoring behavior. In many cases it suffices to do that at the entry-point of the runtime. The return value of a JS function call is now also stored in the scope. Previously, all return values were stored in a ScopedValue, got loaded on return, and immediately stored in another ScopedValue in the caller. This resulted in a lot of stores, where now there is only one store needed, and no extra ScopedValue for every function.
