620778 - JS_IsRunning lies when only natives are active

Status: RESOLVED INVALID

(Core :: JavaScript Engine, defect)

Description

[Blake Kaplan (:mrbkap) (inactive)]

Consider:
JSBool
IsRunning(JSContext *cx, uintN argc, jsval *vp)
{
  *vp = JS_IsRunning(cx);
  return true;
}

setTimeout(isRunning, 0);

In this case, the only "JS" running, will be the fast native. JS_IsRunning looks for stack frames, of which there are none here and will return false, even though JS is running (namely, the native function IsRunning). We should probably fix this.
