Two of our interns finished up their terms recently. The Toronto office feels a little emptier without them, or at least that’s how I imagine it since I don’t actually work in Toronto.

Modernize infrastructure:

Trunk-based Fennec debug builds+tests have been disabled in buildbot and moved to tier 1 in Taskcluster

Improve Release Pipeline:

Mihai finished migrating release sanity to Release Promotion. Release sanity helps to catch release issues that are susceptible to human process error. It has been live since 48.0b9, and has already helped catch a few issues that could have delayed the releases!

Improve CI Pipeline:

Rob created an automated build using taskcluster-github to create new taskcluster windows amis whenever the workertype manifest (or opencloudconfig) is updated.

David Burns posted a status update to dev.platform about the ongoing build system improvements.

Operational:

Balrog has been successfully migrated to the new Docker-based CloudOps infrastructure, which will make development and maintenance much easier.

We’ve ended the experiment of providing Firefox code mirrors on bitbucket. This will allow us to shut down some legacy infrastructure shortly.

We’ve shut down legacy vcs-sync!

Nearly everything that was indexed on MXR has been indexed on DXR! A few stragglers remain, but are very low-use trees. Additionally, mxr.mozilla.org now brings up an interstital page which offers a link to DXR instead of the hardhat.

Many betas died to bring you e10s.

Release:

We’ve released Firefox 48 which brings many long-awaited features to our users.

Outreach

Our amazing interns Francis Kang and Connor Sheehan have finished their tenure with us. They did grace us with their intern presentations before they left, which you can replay on Air Mozilla:

• Diving in to the unknown (Francis) - https://air.mozilla.org/diving-into-the-unknown/
• Release Promotion: Keeping tabs on automation (Connor) - https://air.mozilla.org/release-promotion-keeping-tabs-on-automation/

Thanks to both Connor and Francis for their hard work, and thanks also to their mentors Rail and Kim for helping them become such valuable contributors.

Hiring:

We’ve filled the two release engineering positions we had advertised. It felt like we had an embarrassment of riches at some points during that hiring process. Thanks to everyone who took the time to apply.

See you next week!
