Integrate friendly tips from Tor colleagues to make (or not) 4.5 alpha 3;
This includes removal of overloaded (but unused) methods, and addition of
a overlooked call to DataStruct::SetData(nsISupports, uint32_t, bool.)
1 // Test that you can't call the SavedFrame constructor and can only use
2 // SavedFrame's getters on SavedFrame instances.
4 load(libdir + "asserts.js");
6 let proto = Object.getPrototypeOf(saveStack());
8 // Can't create new SavedFrame instances by hand.
9 assertThrowsInstanceOf(() => {
10 new proto.constructor();
11 }, TypeError);
13 for (let p of ["source", "line", "column", "functionDisplayName", "parent"]) {
14 // The getters shouldn't work on the prototype.
15 assertThrowsInstanceOf(() => proto[p], TypeError);
17 // Nor should they work on random objects.
18 let o = {};
19 Object.defineProperty(o, p, Object.getOwnPropertyDescriptor(proto, p));
20 assertThrowsInstanceOf(() => o[p], TypeError);
21 }
