the jenkins crm build seems to have started failing today, the last builds on these two patch sets show the error (while earlier builds pass): https://gerrit.wikimedia.org/r/#/c/217990/ and https://gerrit.wikimedia.org/r/#/c/218579/
The most obvious problem appears to be the mysql connect string getting a socket of /dev/null

| ci-settings: point MySQL db to 127.0.0.1 | wikimedia/fundraising/crm | master | +4 -1 |
The job runs on the Trusty CI slaves and php is actually HHVM. I have upgraded HHVM yesterday from 3.3.x to 3.6.x (T102616) and our HHVM build does not support MySQL connection over a socket.
The PHP mysql function would attempt to connect over a socket when the hostname is localhost. The workaround is to point it to 127.0.0.1, potentially with the MySQL port as well (3306).
Related patches:
https://gerrit.wikimedia.org/r/#/c/218625/1/bin/mw-set-env.sh,unified (localhost -> 127.0.0.1)
https://gerrit.wikimedia.org/r/#/c/218624/1/bin/mw-install-mysql.sh,unified (add :3306 to $wgDBserver)
Taking the task, will figure out how to change the DB server if I can :-)
Change 218853 had a related patch set uploaded (by Hashar):
ci-settings: point MySQL db to 127.0.0.1
https://gerrit.wikimedia.org/r/218853 switch to TCP connection. Sorry, should have noticed it and do a grep 'localhost' on CI configuration files :/
