Happy weekend, friends of releng!

It’s been a very release and ops heavy week for lots of people on our teams. We were heads down building multiple Firefox releases and dealing with some issues related to load on the Mozilla VCS infrastructure and issues due to infrastructure configuration changes. We’re also working jointly with IT, as we speak, to perform a number of maintenance tasks during our regular tree closing window.

Modernize infrastructure: Dustin and Anthony are working on TTL support in tooltool.

Q brought up another hand-built windows 10 machine to double the available pool size on try. At the same time Callek continues to coordinate with developers in his efforts to green up Windows 10 testing.

Q updated Microsoft Deployment Tools (MDT) to 2013 update 1. XP booting is still being worked on but we took a big step forward in being able to support Windows 10.

Rob determined why our AWS Windows spot instances weren’t spinning up and patched a few bugs in our cloud-tool and slavealloc configurations. Now we need to work on making sure builds function properly. One step closer to having Windows builds in AWS.

Improve CI pipeline: Dustin has been working on running linux builds in a docker image running the latest version of CentOS.

Ben has been working on Buildbot Taskcluster Bridge improvements:

• Implemented payload schema verification
• Correct resolve badly formed Tasks
• Identified a number of key edge cases that need to be handled still

Rail has funsize reporting to production treeherder (https://bugzil.la/725726)

Rail got funsize to generate partial updates 30-50% faster after enabling local diffing cache.

Release: Jordan was point on handling multiple go to build requests and shipping important point releases (40.0.3, 38.2.1).

Operational: Dustin is working on a plan to migrate TreeStatus out of PHX1 and into relengapi in SCL3 as part of the PHX1 exit strategy.

Rail regenerated our git-shared tarball and increased the disk space on our linux64 AWS AMIs in effort to help with the load issues we’ve been experiencing recently on our internal git servers (https://bugzil.la/1199524).

See you again next week!
