ReleaseEngineering/Buildbot Migration

Current state

As of April 2018, only Firefox ESR52 is running in buildbot. Expected EOL is late August / early September 2018.

How do I find where a build/test job is running?

The best approach is the examine the job on treeherder. Click on the job you're interested in, and look at the information on the bottom-left. Taskcluster jobs have [TC] in their name. They also have "Machine: unknown". Buildbot jobs have specific machine names specified, e.g. "Machine: bld-linux64-spot-134"

Relevant source repositories

Buildbot jobs are defined in a pair of repositories:

• buildbot-configs

• buildbotcustom

Taskcluster jobs are mostly defined all in-tree:

• in-tree taskcluster configs*
