commit 60efce445b17d4b4153e91527887873812f5599f Author: Nick Mathewson nickm@torproject.org Date: Mon Feb 22 10:07:42 2016 -0500
Enable ed25519 collator in voting.
Previously, I had left in some debugging code with /*XXX*/ after it, which nobody noticed. Live and learn! Next time I will use /*XXX DO NOT COMMIT*/ or something.
We need to define a new consensus method for this; consensus method 21 shouldn't actually be used.
