[edbrowse-dev] infinite loop

[Karl Dahlke <eklhad@comcast.net>]

This is so absurd that I just have to give up and move on to something else.

which contains this code, slightly cleaned up for readability.

            setCookie: function  (a, w1, w2, extra) {
                extra = extra || {};
                var w = w1 + '=' + w2;
                var c = 0;
                for (var i = 0, l = a['length']; i < l; i++) {
                    var e = a[i];
                    w += '; ' + e;
                    var f = a[e];
                    a['push'](f);
                    l = a['length'];
                    if (f !== !![]) {
                        w += '=' + f;
                    }
                }
                extra['cookie'] = w;
            }

Then invoked like this.

setCookie(['*'], 'counter', 1);

As long as it is called with a nonzero array, it pushes undefined onto the array forever,
incrementing l and i forever, an infinite loop.
Is it not?

Even if it wasn't, the code makes no sense.
c is set but not used.
The whol calculation puts cookie in a local object that is then thrown away.
WTF
I wonder if this site comes up in a real browser, and how it possibly could!
Maybe it's bogus untested code that we're not suppose to be running at all,
and other browsers don't run it but for some reason edbrowse does.
I don't know I'm sort of grasphing.
As I say I'll probably just write this one off for now unless you all have some insight.
