This week from Tuesday to Thursday four Canonical Foundations team members held a virtual sprint about the proposed-migration infrastructure. It’s been a loooong three days and nightshifts, but it was absolutely worth it. Thanks to Brian, Barry, and Robert for your great work!

I started the sprint on Tuesday with a presentation (slides) about the design and some details about the involved components, and showed how to deploy the whole thing locally in juju-local. I also prepared a handful of bite-size improvements which were good finger-exercises for getting familiar with the infrastructure and testing changes. I’m happy to report that all of those got implemented and are running in production!

The big piece of work which we all collaborated on was providing a web-based test retry for all Ubuntu developers. Right now this is limited to a handful of Canonical employees, but we want Ubuntu developers to be able to retry autopkgtest regressions (which stop their package from landing in Ubuntu) by themselves. I don’t know the first thing about web applications and OpenID, so I’m really glad that Barry and Robert came up with a “hello world” kind of Flask webapp which uses Ubuntu SSO authentication to verify that the requester is an Ubuntu Developer. I implemented the input variable validation and sending the actual test requests over AMQP.

Now we have a nice autopkgtest-retrier git with the required functionality and 100% (yes, complete!) test coverage. With that, requesting tests in a local deployment works! So what’s left to do for me now is to turn this into a CGI script, configure apache for it, enable SSL on, and update the charms to set this all up automatically. So this moved from “ugh, I don’t know where to start” from “should land next week” in these three days!

We are going to have similar sprints for Brian’s error tracker, Robert’s CI train, and Barry’s system-image builder in the next weeks. Let’s increase all those bus factors from the current “1” to at least “4” ☺ . Looking forward to these!
