- // obj.getOwnPropertyDescriptor works when obj is a transparent cross-compartment wrapper.
- var g1 = newGlobal('new-compartment');
- var g2 = newGlobal('new-compartment');
- g1.next = g2;
- // This test is a little hard to follow, especially the !== assertions.
- //
- // Bottom line: the value of a property of g1 can only be an object in g1's
- // compartment, so any Debugger.Objects obtained by calling
- // g1obj.getOwnPropertyDescriptor should all have referents in g1's
- // compartment.
- var dbg = new Debugger;
- var g1obj = dbg.addDebuggee(g1);
- var g2obj = dbg.addDebuggee(g2);
- var wobj = g1obj.getOwnPropertyDescriptor("next").value;
- assertEq(wobj instanceof Debugger.Object, true);
- assertEq(wobj !== g2obj, true); // referents are in two different compartments
- g2.x = "ok";
- assertEq(wobj.getOwnPropertyDescriptor("x").value, "ok");
- g1.g2min = g2.min = g2.Math.min;
- g2.eval("Object.defineProperty(this, 'y', {get: min});");
- assertEq(g2.y, Infinity);
- var wmin = wobj.getOwnPropertyDescriptor("y").get;
- assertEq(wmin !== g2obj.getOwnPropertyDescriptor("min").value, true); // as above
- assertEq(wmin, g1obj.getOwnPropertyDescriptor("g2min").value);
