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 // frame.eval can evaluate code in a frame pushed in another context. Bug 749697.
3 // In other words, the debugger can see all frames on the stack, even though
4 // each frame is attached to a particular JSContext and multiple JSContexts may
5 // have frames on the stack.
7 var g = newGlobal();
8 g.eval('function f(a) { debugger; evaluate("debugger;", {newContext: true}); }');
10 var dbg = new Debugger(g);
11 var hits = 0;
12 dbg.onDebuggerStatement = function (frame1) {
13 dbg.onDebuggerStatement = function (frame2) {
14 assertEq(frame1.eval("a").return, 31);
15 hits++;
16 };
17 };
19 g.f(31);
20 assertEq(hits, 1);
