At the release team BoF at this years Guadec, I said I would write a blog post about the whats and hows and ifs of release team work. I’m a little late with this, but here it is: a glimpse into the life of a GNOME release team member.
We are in the end phase of the development cycle, when the release team work is really kicking into high gear.
Since the .90 release, we’ve been tracking blocker bugs. The way this works is that we are setting the GNOME Target field to the next release. During the cause of the development cycle, we’ve had 50 bugs that were marked with
at some point . Today, we’re down to a single one, which will hopefully be gone before the weekend is over.
We don’t have formal criteria for what bugs to mark as blockers, we are mostly going by the instinct and experience of bug zapping veterans like Andre Klapper. My own criteria for setting this flag mostly come down to these questions:
Is it a crash in a core component ? Is it very visible or annoying ? Will it affect many users ?
For finding bugs that should be blockers, I am regularly scanning all incoming bugs in bugzilla. On an average day this query finds between 100 and 200 bugs – with some practice, one can get through that list in 15 minutes.
We also get ‘nominations’ for blockers from maintainers and developers, which is very helpful.
The duty of ‘doing’ releases is distributed among all of the current, active release team members.
Our development schedule has a pretty well-established cadence of development releases: We do a number of early development snapshots which are roughly a month apart (3.13.1, 3.13.2, 3.13.3 and 3.13.4 this cycle), followed by the beta releases which are 2 weeks apart (3.13.90, 3.13.91, 3.13.92, this cycle).
Most of the mechanics of creating the modulesets by rewriting our regular modulesets (which point at git repositories, not tarballs), and creating those symlinks on the server are handled by scripts that have been passed down through the generations.
The time-consuming aspect of creating a release is that it usually takes several attempts to create candidate modulesets, hunt down missing releases (or doing them ourselves – which is sadly necessary for a number of ‘weakly maintained’ modules), and do a full jhbuild using the final modulesets. As a consequence, while our official release day is always Monday, the release typically happens on Wednesday or Thursday of the same week.
Towards the end of a development cycle, the release team also starts to plan for the next cycle.
This includes creating the schedule, taking a look at annoying bugs that we should tackle in the next cycle, figuring out if there are project-wide goals that we should push, and collecting input on new modules and features that people want to work on for the next release.
Since we are at this point right now, let me end with this request:
Please let us know what features are on your modules roadmap for the next cycle!
