commit 461dbeba80ad43f043d39cddae7e9d0e38fc3dd4
Author: David Fifield <[email protected]>
Date: Tue Aug 1 15:06:53 2017 -0700
Make capacity a uint.
This prohibits some nonsense like "./proxy-go -capacity -550", which
otherwise results in a panic like:
INFO: configuration.go:174: Created Configuration at
&{[{[stun:stun.l.google.com:19302] }] All Balanced }
panic: makechan: size out of range
