Hey all,
As of today, we will no longer be building packages for upstream ceph.git branches each time a PR is merged. Instead, we will build each active (master, pacific, octopus, nautilus) branch twice daily ONLY if there were changes since the last build.
https://github.com/ceph/ceph-build/pull/1743 makes this change.
This job is now disabled: https://jenkins.ceph.com/view/all/job/ceph-dev-trigger/
This job will handle ceph.git dev builds: https://jenkins.ceph.com/job/ceph-dev-nightly/
The purpose of this change is to reduce the load on the CI builders.
The way teuthology-suite currently works, as a side effect of this change I think we would need to supply a rather large "-n <number of not-yet-built revisions that are allowed to be skipped>" argument when scheduling suites against release branches. Previously "-n 3" was almost always enough and it took a minute or two for teuthology-suite to figure it out. Now with only two builds per day, it is going to be more like 30 and take a long time. The problem is that instead of querying shaman for the latest revision that is built on all distros and jumping right there, teuthology-suite just tries the tip, then goes back one commit, then two commits, etc. Not sure how often folks schedule suites against release branches, but we probably want to prioritize fixing this quirk. Thanks, Ilya
