After restart, the bot joins only #wikimedia-cloud by default. Other channels are joined when the first relevant message to them is supposed to be sent.
The bot polls the phabricator API, listens to the Gerrit events feed, and posts changes to tasks and patches into various IRC channels.
- wikibugs.py: Runs as
wb2-phaband polls the API, and inserts all task events into a redis queue
- grrrrit.py: Runs as
wb2-grrrritand listens to the Gerrit stream-events feed, and inserts all changes events into a redis queue
- redis2irc.py: Runs as
wb2-irc, reads from the redis-queue, and notifies various channels.
- redis2stdout.py is useful when debugging if you don't want to have to connect to IRC all the time.
The source for wikibugs can be found in Git:
You need to ssh into tools-login.wmflabs.org and run the following commands:
become wikibugs # sudo -i become wikibugs if you're in sudoers but not a member of tools.wikibugs cd ~/wikibugs2
Since Gerrit change 455347 deployment is performed using a 'manage.py' script in the tool directory.
The manage.py script provides the following commands:
python3 manage.py deploy [job name] [job name]
- This will pull changes, and will restart the jobs provided (see above for job names)
- If no job names are provided, all jobs will be restarted
python3 manage.py pull
- pulls changes into the working directory
python3 manage.py start_job [job name]
- Starts (i.e., jsub) the provided job
python3 manage.py start_jobs
- This will start all jobs.
python3 manage.py restart_job [job name]
- Restarts (i.e., qmod -rj) the provided job
There is currently no IRC-based method for this. Maintainers can kill the phabricator listener via:
user@tools-bastion-03:~$ become wikibugs tools.wikibugs@tools-bastion-03:~$ qstat job-ID prior name user state submit/start at queue slots ja-task-ID ----------------------------------------------------------------------------------------------------------------- 4602105 0.39032 wb2-phab tools.wikibu r 03/24/2016 04:29:15 email@example.com 1 5736318 0.32072 lighttpd-w tools.wikibu r 04/28/2016 04:15:16 webgrid-lighttpd@tools-webgrid 1 6049120 0.30351 wb2-irc tools.wikibu r 05/06/2016 19:56:31 firstname.lastname@example.org 1 tools.wikibugs@tools-bastion-03:~$ qdel 4602105

cd wikibugs2and run
python3 manage.py start_jobs.
Making wikibugs ignore certain usersEdit
In the case of a vandal attacking Phabricator, you likely want to quietly cause the bot to drop their messages (so Freenode stops killing the bot for flooding) without giving them the recognition of a commit.
redis2irc.py, there is a function named
handle_useful_info with an ignored tuple in it. Add the username to the tuple on labs,
qdel wb2-irc, wait for it to disappear from
qstat, then on your machine
fab start_jobs. Then let it run for a while until the vandal's account has been disabled and all their messages have been popped from redis. Then reverse the change.
During this it will still be processing their phabricator edits behind the scenes so depending on volume it may be slow to post things to IRC.
Update channels.yaml or gerrit-channels.yaml with the channel name and project name. Project names can be regular expressions and are case insensitive.
Note that before wikibugs can be added to a new channel, it must be whitelisted by freenode staff (gerrit:454263 has some more details). wikibugs maintainers will take care of this step when necessary.
Find any of the following friendly people on IRC and they should be able to help you out:
The list of people who have access to the bot can be found here.
The first wikibugs, started in August 2004, was a Perl script that parsed Bugzilla's email messages, wrote them to a log file, and relied on ircecho to post them. In April 2014, the bot was rewritten in Python ("pywikibugs"), still parsing email messages, but using a Redis queue to post on IRC. Later in November 2014, the bot was rewritten again ("wikibugs2"), this time handling bugs from Phabricator rather than Bugzilla, but reused many of the ideas from pywikibugs such as a Redis queue and asyncio.
