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 // Array.prototype.pop does a strict assignment to this.length even if the
2 // caller is nonstrict. Bug 886087.
4 load(libdir + "asserts.js");
6 // obj.length is read-only
7 var obj = {pop: [].pop, 0: "zero"};
8 Object.defineProperty(obj, "length", {configurable: true, value: 1, writable: false});
9 assertThrowsInstanceOf(() => obj.pop(), TypeError);
11 // obj.length has only a getter
12 obj = {pop: [].pop, 0: "zero", get length() { return 1; }};
13 assertThrowsInstanceOf(() => obj.pop(), TypeError);
