REQUEST FOR URGENT BUSINESS RELATIONSHIP

FIRST, I MUST SOLICIT YOUR STRICTEST CONFIDENCE IN THIS MIGRATION. THIS IS BY VIRTUE OF ITS NATURE AS BEING UTTERLY CONFIDENTIAL AND ‘TOP SECRET’. I AM SURE AND HAVE CONFIDENCE OF YOUR ABILITY AND RELIABILITY TO HANDLE A TASK OF THIS GREAT MAGNITUDE INVOLVING A PENDING MIGRATION REQUIRING MAXIMUM CONFIDENCE.

WE ARE TOP OFFICIAL OF THE RELENG TEAM WHO ARE INTERESTED IN MIGRATION OF TASKS INTO TASKCLUSTER WITH JOBS WHICH ARE PRESENTLY TRAPPED IN BUILDBOT. IN ORDER TO COMMENCE THIS BUSINESS WE SOLICIT YOUR ASSISTANCE TO ENABLE US MIGRATE INTO YOUR TASKGRAPH THE SAID TRAPPED JOBS.

Modernize infrastructure:

The ongoing work to get TaskCluster building Firefox on Windows reached an important milestone with our first Mozharness based build going green in the TreeHerder dashboard. This represents underlying effort in documenting the dependency chain for Windows builders and producing simple manifests that give greater transparency to changes in this area.

Alin, Amy, and Van brought 192 new OS X 10.10.5 Mac minis online. This should eliminate our Yosemite backlog and allow us to enable more e10s tests.

Q, catlee, and jmaher migrated the first batch of Windows 7 tests to AWS this week. Currently we’re running these suites for all branches of gecko 49 and higher: Web platform tests + reftests, gtest, cppunit, jittest, jsreftest, crashtest. This will reduce our reliance on hardware and allow us to scale dynamically. They are still working on greening larger sets of tests which are more sensitive to their operating environment. Once we have moved a significant portion of tests, we can add additional e10s tests on w7 as well.

Improve Release Pipeline:

In the interest of making progress on migrating Nightly builds to TaskCluster, we had a meeting last week to discuss the security requirements around our nightly release process. Based on the discussions in that meeting, Aki is now iterating on a “one graph” solution for Nightlies (as opposed to a two-graph approach where signing is separate). If this approach works, i.e. we can’t find major security holes in the proposed model, it will simplify our process greatly.

Improve CI Pipeline:

We have achieved our first deprecation milestone in the TaskCluster migration by turning off Linux 64-bit debug builds/tests for aurora/trunk branches in buildbot. These bugs are only generated in TaskCluster now.

Aki added scriptworker to readthedocs: http://scriptworker.readthedocs.io/en/latest/

Operational:

We had a planned tree closing window over the weekend where, amongst other things, we upgraded our database hosts. It went smoothly, so you probably didn’t even notice.

Our new buildduty associates from Taipei were able to successfully loan machines to developers for the first time last week. Welcome aboard!

Release:

Lots of releases published or in-flight: Firefox 47 betas 3-5, Fennec 47.0b4, and Thunderbird 38.8.0 and 45.1.0. As always, you can find more details in our post-mortem wiki pages:
