| 1 // Asking for the script of a Debugger.Object should work, even when lazy | |
| 2 // functions are involved. | |
| 3 | |
| 4 // Note that we never hand out the scripts of non-debuggee functions, and | |
| 5 // putting a compartment in debug mode automatically de-lazifies all its | |
| 6 // functions. (This ensures that findScripts works, too.) | |
| 7 // | |
| 8 // So here we create a reference to a non-debuggee function, verify that we | |
| 9 // can't access its interesting properties, make it a debuggee, and verify | |
| 10 // that everything becomes available. | |
