New issue 3404 by [email protected]: CaptureStackTrace's stack
accessors reconfigure unconfigurable properties
http://code.google.com/p/v8/issues/detail?id=3404
var e;
try { throw new Error(); } catch (x) { e = x; };
// Reconfigure e.stack to be non-configurable
var d = Object.getOwnPropertyDescriptor(e, "stack");
Object.defineProperty(e, "stack", {get:d.get, set:d.set, configurable:
false});
e.stack;
Object.getOwnPropertyDescriptor(e, "stack")
--> {get: function () { [native code] }, set: function () { [native code]
}, enumerable: false, configurable: true}
Additionally, d.get != the new .get, so this leaks into JS.
What I guess we'd want instead is something like the following:
function create_getter() {
function actual_getter() {
var result = format_stack_trace();
actual_getter = function() { return result; }
return result;
}
return function() { actual_getter(); }
}
