* Fix dead temporal zone checking in module namespacesSimon Hausmann2018-08-291-0/+1
| | | | | | | | | | | | | | | Accessing uninitialized imports through the module namespace object should throw a reference error. Unfortunately we can't do this check on the caller side of the namespace object get, as we have no idea that we're talking to one. Therefore we must throw in the vtable methods. When checking via Reflect.has(), the properties should be reported as existing. This means providing a virtual hasProperty() in the module as well as changing Reflect::method_has to use the vtable method instead of doing a get (which would throw).

At the same time, expose them on TypedArray's prototype: - 22.2.3.15 %TypedArray%.prototype.keys - 22.2.3.29 %TypedArray%.prototype.values - 22.2.3.6 %TypedArray%.prototype.entries - 22.2.3.31 %TypedArray%.prototype[Symbol.iterator] For TypedArray, test coverage improves a tiny bit (3 passing tests), but the vast majority fail as it seems like the object structure for TypedArray is currently incomplete as far as ES6 expects. It seems that ES6 expects the object structure to be: * %TypedArray% (inherits FunctionObject) (this is the TypedArray intrinsic object, and responsible for initializing the TypedArray instances) * All the TypedArray ctors (e.g. UInt8Array) These inherit %TypedArray%, and make a super call to it to do their work * %TypedArrayPrototype% (inherits Object) (this is the initial prototype for %TypedArray%) * All the ctors have their own separate instance of this * The instances also make use it So, for instance, a lot of the tests attempt to access the prototype like: var proto = Object.getPrototypeOf(Int8Array) var keys = proto.prototype.keys As ES6 expects Int8Array.prototype to be %TypedArray% (22.2.5), this expands to: Object.getPrototypeOf(%TypedArray%) which it expects to be %TypedArrayPrototype%. But since we have no intrinsic object, and the ctors inherit FunctionObject, we instead return the wrong prototype into 'var proto'.

Some further work on QV4::String and in a few other places is required before we can get remove the compatibility.

* V4: Pass scope around as parameters inside the runtime.Erik Verbruggen2016-06-221-2/+2
| | | | | | | | | | | | | | | | 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.
