Need To Know
(Release and system issues that may impact engineering this week.)
|Next Merge: December 10, 2018||Next Release: December 11, 2018|
|Central: 65||Aurora: 54||Beta: 64||Release: 63.0.1|
- Desktop beta3 build didn't ship because of a Windows PGO build timeout
- Desktop beta4 will be live today
- Mobile beta4 will be live tomorrow
Build Changes (gps)
(Build changes of which engineers should be aware.)
(Repo, test, and other information for engineers from the release engineering team.)
- Have switched our Amazon instances to use SSD backed EBS volumes. The goal is further cost reduction in AWS since we used to pay quite a bit for I/O on the old EBS volumes, but I/O on the new SSD volumes is free. We may see some slight performance wins as well.
- bug 1028341, bug 1027390
- Please let us know if you see some bustage that could be due to this!
(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: 9.67 (Previous Week: 7.36).
- 25 intermittent failures fixed in the last week - List - Thanks!.
- Thanks to JW Wang for continuing to plug away at various media oranges, including some very longstanding ones.
- Andrew McCreight LSan for Mochitests on TBPL. LSan is a tool that can find leaks in C++ code, and it's already found lots -- see the blocking bugs in the tracking bug. Great stuff! Please help with fixing the existing leaks whose reporting has been suppressed in order to get this landed.
- current numbers still do not look good, except Android release.
- Still looking for older Intel integrated graphics machine to reproduce bug 988549 which continues to be high on 31 beta.
- OMTC on Windows still too unstable, needs deactivation (sorry).
- Android beta: bug 827264 (NSS shutdown) - needs nsSocketTransportService dev
- Android Nightly: bug 1028802 (mozilla::gfx::AlphaBoxBlur::Blur) - needs dev
- Desktop Nightly: bug 1028902 (js::GetLengthProperty), bug 1028904 (js::StringObject::setStringThis), probably connected, need dev
(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.)
