Implement a real Private Browsing Mode condition by changing the API/ABI;
This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.
1 // Throwing an exception from an onPop handler when yielding terminates the debuggee
2 // but does not close the generator-iterator.
4 var g = newGlobal();
5 var dbg = new Debugger;
6 var gw = dbg.addDebuggee(g);
7 dbg.onDebuggerStatement = function handleDebugger(frame) {
8 frame.onPop = function (c) {
9 throw "fit";
10 };
11 };
12 g.eval("function g() { for (var i = 0; i < 10; i++) { debugger; yield i; } }");
13 g.eval("var it = g();");
14 assertEq(gw.evalInGlobal("it.next();"), null);
16 dbg.enabled = false;
17 assertEq(g.it.next(), 1);
