One of releng’s big goals for Q1 is to deliver a beta via build promotion. It was great to have some tangible progress there this week with bouncer submission.

Lots of other stuff in-flight, more details below!

Modernize infrastructure:

Dustin worked with Armen and Joel Maher to run Firefox tests in TaskCluster on an older EC2 instance type where the tests seem to fail less often, perhaps because they are single-CPU or slower.

Improve CI pipeline:

We turned off automation for b2g 2.2 builds this week, which allowed us to remove some code, reduce some complexity, and regain some small amount of capacity. Thanks to Vlad and Alin on buildduty for helping to land those patches. (https://bugzil.la/1236835 and https://bugzil.la/1237985)

In a similar vein, Callek landed code to disable all b2g desktop builds and tests on all trees. Another win for increased capacity and reduced complexity! (https://bugzil.la/1236835)

Release:

Kim finished integrating bouncer submission with our release promotion project. That’s one more blocker out of the way! (https://bugzil.la/1215204)

Ben landed several enhancements to our update server: adding aliases to update rules (https://bugzil.la/1067402), and allowing fallbacks for rules with whitelists (https://bugzil.la/1235073).

Operational:

There was some excitement last Sunday when all the trees were closed due to timeouts connectivity issues between our SCL3 datacentre and AWS. (https://bugzil.la/238369)

Build config:

Mike released v0.7.4 of tup, and is working on generating the tup backend from moz.build. We hope to offer tup as an alternative build backend sometime soon.

See you all next week!
