Build Changes (gps)

(Build changes of which engineers should be aware.)

RelEng (catlee)

(Repo, test, and other information for engineers from the release engineering team.)

Upcoming Outages/Upgrades

(System outages/upgrades and tree closures that impact engineering.)

• Tree Closing Window on Saturday, November 15. bug 1087431 is the tracker.
  • The November 8 window reported last week was postponed to avoid conflicts with decade builds. Final notice is given to the dev groups when everything is "go".
  • An unusually long window -- approx 11-1/2 hours.
  • Most of the work is network related, with interruptions in traffic from time to time.
  • We'll leave trees "open", but developers should expect longer than normal build times and potential need to restart some jobs.

Quality Programs

(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)

OrangeFactor (ryanvm)

<Read Only>

• Past week's OrangeFactor: 5.16 (last week: 8.38).

Stability (kairo)

• bug 1096492 (crash in workers) is >2.5% of 33.1 crashes, might drive a 31.1.1, we need help there
• Otherwise, please concentrate stability work on Aurora/DevEdition and Nightly now, Beta 34 is good.

A*Team (jgriffin)

Mochitest test isolation and --run-by-dir
