1) This was Ben Hearsum’s first time doing a release. He works in the Release group, and he’s smart, but he’s never done a release for Mozilla. Ever. The fact that he jumped into doing this release with absolutely no advance notice, and was able to use our existing automation without needing to ask any questions at all says lots about both Ben and how things are improving.
2) From Build’s point of view, this was a fast release. We took 2 days 8 hours, which is one of our fastest releases ever. Note: between the “Dev says go to build” and “build started” was a delay of 1 day 4 hours where Build did nothing. This delay was because we were busy with 3.0beta4 and also trying to balance out some other workloads across the group. I counted this delay as part of our 2days 8 hours, but I have to point out that if we had been ready, our total time for FF22.214.171.124 would actually been halved; we would have only needed a totally screaming fast 1day 4hours.
4) Like before, we waited until morning to start pushing to mirrors. This was done so mirror absorption completed as QA were arriving in the office to start testing update channels. We did this because we wanted to reduce the time files were on the mirrors untested; in the past, overly excited people have post the locations of the files as â€œreleasedâ€ on public forums, even though they are not finished the last of the sanity checks. Coordinating the mirror push like this reduced that likelihood just a bit.
5) Mirror absorption took 1 hour to reach all values >= 50%, slightly faster and slightly lower then our usual threshold.
