Upcoming Outages/Upgrades

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

• Saturday, September 20, is the Tree Closing Window. See bug 1065514 for details. hg.mozilla.org will be offline for a period of time, so trees will be closed. This is likely to be from 0900-1300PT, but time will be confirmed on Wednesday. Look for the notice with final times later this week.

Quality Programs

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

MemShrink (njn)

• No update.

Team Stand-ups

(In <2 mins, what did your team accomplish last week, on what is your team working on this week, and on what, if anything, is your team blocked? No questions during the stand-ups. All questions should be asked during the roundtable.)

A*Team (jgriffin)

<Read Only>

Blog and newsgroup posts:

• [armenzg] Running TBPL jobs locally with HTTP authentication and related dev.platform post
• [gbrown] Running my own Autophone
• [wlach] Hacking on the Treeherder front end: refreshingly easy
• [AutomatedTester] Marionette mailing list

Developer Tools (prouget)

Electrolysis (e10s) (blassey)

• Please help dogfood e10s in Nightly!
  • Just flip the "browser.tabs.remote.autostart" pref to true and restart Nightly.
  • Known issues: https://wiki.mozilla.org/Electrolysis#What_to_Expect
• e10s bugs fixed in the last week: http://is.gd/ksQL9N
• To get more testing from Nightly users:
  • bug 1064885 - Added e10s opt-in prompt in Nightly
  • bug 1064886 - Added "Enable E10S" checkbox in Firefox Preferences pane
  • Disable e10s if a11y (bug 1047076) or safe mode bug 1063848 are enabled (to avoid known issues, for now)
  • We might enable e10s for all Nightly users (for just one day) to get broader testing during Nightly 36. So now is a good time to report any critical e10s bugs you are seeing.
