Hello all,
I want to apologize for the current slowness in our CI stack. Everything is working fine in the sense that nothing is broken.
We simply did not adequately prepare for the switch to php5.5 being the new minimum version for MediaWiki. This resulted in a large influx of jobs on a set of our Jenkins executers that was not a large enough pool. Timo and Antoine have created more executers to help mitigate [0].
More explicitly: due to package version availability in Ubuntu, our php5.3 jobs run on our pool of Ubuntu Precis hosts, while the php5.5/hhvm jobs run on our pool of Ubuntu Trusty hosts.
Both sets of jobs are in our pipeline to migrate to the new Nodepool system that allows burstable availability of executers.
Again, apologies for the delays but know that the jobs will complete just not as fast as you are accustomed to.
Greg
