Need To Know
(Release and system issues that may impact engineering this week.)
|Next Merge: TODAY||Next Release: November 21, 2023|
|Central: 122||Aurora: 54||Beta: 121||Release: 120|
- It's release day! Firefox 32 is live.
- Tracking for Fennec 32: bug 1060009 - Investigate native crash at /dev/ashmem/libmozalloc.so reported on Google Play
- Firefox ESR 24.8.0 and 31.1.0 are also live.
- This is the last release for ESR24. This means we're back to a single ESR31 train.
- Next up
- 33 beta1 is scheduled to ship on Thursday
- 34 aurora updates are scheduled to be re-enabled on Friday
- Reminder that the merge is happening today
Build Changes (gps)
(Build changes of which engineers should be aware.)
(Repo, test, and other information for engineers from the release engineering team.)
(System outages/upgrades and tree closures that impact engineering.)
(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)
- Past week's OrangeFactor: 5.01 (last week: 3.67).
- Lots of fallout from pre-uplift landings (B2G feature landings, MediaStreamGraph refactor, etc) along with more infra issues.
- Widespread Android 4.0 failures continue to be a problem - now being tracked in bug 1059797.
- 23 intermittent failures fixed in the last week - List - Thanks!.
- another week in the right direction :)
- Byron Campen fixed a truckload of memory leaks in WebRTC code. The LSAN suppressions file now has 23 fewer entries!
- David Major implemented the collection of (anonymized!) memory reports on OOM crashes, and the first such reports are trickling in. Hopefully this will give insight into causes of OOMs in the field.
- [Overall numbers] look OK for 32 beta and 31 release.
(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.)
