Firefox 47 Post-mortem

(Ritu) Triage with Engineering Boss for 47 (overholt) was super helpful.

• We should do it once a week through out the Beta cycle

(Ritu) Platform triage helped

• We are still figuring out ways to plan and track fixes for a version but triaging new regressions with devs was very valuable.

(Ritu) Need missed uplifts dashboard, monitoring

• This could be a ToDo for release management,
• This might be a part of ship-it.

(Ritu) Release build promotion and the 4 hour wait for opt/pgo builds to finish(!!!)

• Release BP is a great initiative. In V1.1 or V2, we need a mechanism to not prevent ship-it builds from being requested until PGO/OPT builds finish.
• Callek said RelEng plans to address this but Fenne release build promotion is taking precedence.

(Ritu) Release blockers

• Amazon video playback
• Netflix broke with Widevine uplift
• Crash spikes since we enabled D3D11 by default
  • We discussed a bit about turn around time on investigating and fixing crash bugs.

(syl) Addon signing disabled at the last minute

• Caused a startup crash with selenium
• Ritu to work with David to figure out whether Selenium and Marionette WebDriver testing can be added as a Beta10 sign off criteria.

(syl) balrog update bug (0% wasn't working) [Bug 1282838

• RelEng mentioned this was a one-time issue and should be fixed soon.
• In the meantime, 47 -> 47.0.1 has been set to 1% instead of 0%.
