The Need To Know
(Release and system issues that may impact engineering this week.)
- Firefox 29 has shipped
- Firefox 24.5.0 ESR also
- Firefox 30.0beta1 is with QA - release date is Thurs May 1
- Firefox 31.0a2 Aurora updates will be unthrottled on Friday May 2 after QA signs off
|Next Merge: July 3, 2023||Next Release: July 4, 2023|
|Central: 116||Aurora: 54||Beta: 115||Release: 114|
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: 10.29 (Previous Week: 11.23).
- Thanks to Randell Jesup and JW Wang for fixing a number of media test crashes/failures.
- Thanks to Nathan Froyd for investigating and fixing common patterns contributing to test instability.
- Joel Maher pushing ahead with mochitest-bc run-by-dir work (bug 992911). Please take a look at dependencies of that bug for work that needs to be done so this work can land.
- 22 intermittent failures fixed in the last week - List - Thanks!.
- uptick in sec bugs delta this week. Your attention appreciated.
- Bobby Holley implemented the discarding of chrome script source code on B2G. This saves 1.26 MiB on Tarako (a big deal!) and a bit more on other B2G devices.
- We've had two out-of-band MemShrink meetings recently to deal with a surge of Tarako-related bugs, many of which are of the form "Do something in app A, then something in app B, and app A and/or B crashes due to OOM". Some of these can be fixed by fixing one thing, but the device has so little memory that for many of them won't be fixed without root-and-branch memory optimization efforts.
- Overall numbers look good, with the exception of Android Nightly, but the bugs there are well-tracked and being worked on.
- In fact, the most-recent data for beta on both desktop and Android show that we should have fixed all crash-volume-regressions just in time and should have a pretty decent release out the door today!
(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.)
App Tools (prouget)
B2G Services (dougt)

- bug 997446 - Add "Open e10s Window" to hamburger menu (to make testing easier for our Windows friends)
- Getting help from some contributors working on Good First Bugs.
- Website to track add-on compatibility coming soon!
