Is this thing on?
It’s PTO season and many people have taken a few days or week off. While they’re away, the team continues making progress on a variety of fronts. Planning also continues for GoFaster and addon-signing, which will both likely be significant projects for the team in Q4.
Treeherder: camd rolled out a change which collapses chunked jobs on Treeherder, reducing visual noise. In the future, we plan on significantly increasing the number of chunks of many jobs in order to reduce runtimes, so this change makes that work more practical. See camd’s blog post. emorley has landed a change which allows TaskCluster job errors that occur outside of mozharness to be properly handled by Treeherder.
Automatic Starring: jgraham has developed a basic backend which supports recognizing simple intermittent failures, and is working on integrating that into Treeherder; mdoglio is landing some related database changes. ekyle has received sheriff training from RyanVM, and plans to use this to help improve the automated failure recognition algorithm.
Perfherder and Performance Testing: Datazilla has finally been decommissioned (R.I.P.), in favor of our newest performance analysis tool, Perfherder. A lot of Talos documentation updates have been made at https://wiki.mozilla.org/Buildbot/Talos, including details about how we perform calculations on data produced by Talos. wlach performed a useful post-mortem of Eideticker, with several takeaways which should be applicable to many other projects.
MozReview and Autoland: There’s a MozReview meetup underway, so expect some cool updates next time!
TaskCluster Support: ted has made a successful cross-compiled OSX build using TaskCluster! Take it for a spin. More work is needed before we can move OSX builds from the mac mini builders to the cloud.
Mobile Automation: gbrown continues to make improvements on the new |mach emulator| command which makes running Android tests locally on emulator very simple.
General Automation: run-by-dir is live on opt mochitest-plain; debug and ASAN coming soon. This reduces test “bleed-through” and makes it easier to change chunking. adusca, our Outreachy intern, is working to integrate the try extender into Treeherder. And ahal has merged the mozharness “in-tree” configs with the regular mozharness config files, now that mozharness lives in the tree.
Firefox Automation: YouTube ad detection has been improved for firefox-media-tests by maja, which fixes the source of the top intermittent failure in this suite.
Bughunter: bc has got asan-opt builds running in production, and is working on gtk3 support.
hg.mozilla.org: gps has enabled syntax highlighting in hgweb, and has added a new JSON API as well. See gps’ blog post.
