commit 1196ed7cc4fc202e43ca102a73befe62aa65767d Author: Nick Mathewson nickm@torproject.org Date: Mon Aug 18 13:19:43 2014 -0400
Fix relay_command_to_string(); solve 12700.
Two bugs here: 1) We didn't add EXTEND2/EXTENDED2 to relay_command_to_string().
2) relay_command_to_string() didn't log the value of unrecognized commands.
Both fixed here. --- changes/bug12700 | 10 ++++++++++ src/or/relay.c | 8 +++++++- 2 files changed, 17 insertions(+), 1 deletion(-)
