IRC Bot Consolidation¶
Reduce the number of IRC bots and ensure they can operate in all channels.
We have a couple of IRC-related problems converging:
Too many channels (more than limit of 120 per connection)
Lots of individual bots, which all must be configured and all have that limit
Bots are written for different frameworks
Difficult to react to spam in one or more channels across so many
We use supybot for channel and meeting logs. It is not under active development, but it has a successor called Limnoria, which is in later Ubuntu releases (after xenial). It’s python and is easy to install in a venv in the interim. Using it lets us continue to use our existing meetbot system, which is the most difficult part of our irc services to change. Our other bots are mostly home-grown and could be ported fairly easily. With it, we can have the same bot instance participate in all channels by using its ability to support multiple connections. That will let us log all 186 channels, hold meetings in them, send status updates, gerrit notifications, etc, with one config.
The following config example illustrates how to use the multiple connection feature of limnoria to address the channel limit:
supybot.networks: freenode1 freenode2 supybot.networks.freenode1.nick: openstack1 supybot.networks.freenode2.nick: openstack2 supybot.networks.freenode1.servers: chat.freenode.net:6667 supybot.networks.freenode2.servers: chat.freenode.net:6667 supybot.networks.freenode1.channels: #openstack supybot.networks.freenode2.channels: #openstack-infra
We could switch to errbot, though we would additionally need to address the meetbot and logging functionality we currently use with supybot, as well as develop a new method of updating configuration.
Your name here.
Use Gerrit topic “ircbots” for all patches related to this spec.
git-review -t ircbots
Install limnoria on eavesdrop, to replace supybot
Configure freenode1 and freenode2 networks, using openstack1 and openstack2 nicks
Add all channels to the config, splitting across freenode1 and freenode2
Set all channels to extban based on #openstack so it’s easy to update a global ban list.
Add a plugin to watch for highlight spam, and automatically kick accounts and add a ban to #openstack
Auto-generate the limnoria config based on a yaml file with channel descriptions
Convert statusbot into a plugin and retire
Convert gerritbot into a plugin and retire
Convert recheckwatch into a plugin and retire
Changes to eavesdrop.o.o and other servers which currently run bots.
Bot configuration docs should be updated in infra-manual.
This will probably put an unprivileged gerrit ssh key on eavesdrop, but otherwise should not adversely affect security posture. Ceasing to run gerritbot on review.o.o is a likely security benefit.
