Hello,
For a few hours, the Jenkins job mediawiki-core-install-sqlite has simply disappeared. I must have made a mistake this afternoon that deleted it. The end result is that changes that have been voted CR+2 would not complete the unit tests and were not merged by Jenkins.
I have recreated the missing job and it is working again.
If you want to resubmit a change, simply vote CR+2 on it and Jenkins wil rerun the tests for you.
Sorry for the inconvenience.
