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

Upcoming Outages/Upgrades

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

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: 9.26 (Previous Week: 7.65).

<Read Only>

  • Overall numbers are late in coming in today (you might still see errors), but significantly improving, esp. for 31 beta (on aurora, bad older builds still overshadow the improved situation of current builds).
  • Thanks for everyone who helped getting 31 into shape (backing out gfx blacklisting changes, disabling GGC, blocklisting crashing adware DLLs, etc.) so we now seem to look decent for release.

irc #planning Log From This Meeting

11:06 overholt: clouserw, maybe it'd be neat to have a marketplace update every once in a while at this meeting
11:10 dveditz: cpeterson: jedp isn't here anymore... maybe take the Identity section out of the template or find a new owner?
11:11 cpeterson: dveditz: thanks. do you have a owner in mind? :)
11:12 dveditz: no, I don't know what's up there these days
