Need To Know

(Release and system issues that may impact engineering this week.)

Notices/Schedule (lsblakk/sylvestre)

• Firefox Desktop & Android 30.0 is live
  • 25% of pop being offered updates for 24 hours (this is an experiment in uptake/reducing throttling time)
• Firefox ESR 24.6.0 live
• FF31 beta 1 will gtb within the next few hours
• Aurora updates are currently disabled, re-enabling on Friday once QA signs off
• Might need to disable OMTC for FF32 as it is responsible for 5 of the top crashers on that channel right now

Next Merge: November 10, 2025		Next Release: November 11, 2025
Trains
Central: 146	Aurora: 54	Beta: 145	Release: 144

Build Changes (gps)

(Build changes of which engineers should be aware.)

RelEng (catlee)

(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: 9.66 (Previous Week: 8.05).
• No changes from last week: OSX 10.6 mochitest-4 continues to timeout and B2G continues to crash. More tests featured here previously disabled prior to the uplift.
  • bug 947531, bug 891840, etc.
• #4: bug 1014355 - Intermittent Linux "ABORT: X_FreePixmap: BadPixmap (invalid Pixmap parameter)" in nsX11ErrorHandler.cpp.
  • needinfo? Bas pending since 30-May (comments 38, 39, and 46).
• 26 intermittent failures fixed in the last week - List - Thanks!.
  • Thanks to Drew Willcoxon for fixing bug 870205, a frequent source of pain.

MemShrink (njn)

• I missed this last week: Emanuel Hoogeveen fixed a problem with our page allocator in the JS engine that can lead to virtual OOMs even when there's address space available. This may help significantly reduce the virtual OOM rate on Win32. Emanuel is working on a similar fix for jemalloc.

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.)

Developer Tools (robcee)

• bug 1016578 Inject script libraries into content via GCLI
• bug 1005909 Clickable Links in console output
• bug 907310 Reload key commands available in detached devtools toolbox
• bug 911209 Show hidden (display:none) nodes differently in inspector
• bug 718250 Show node dimensions in highlighter
• bug 1017790 Expose category information in Profiler data
• bug 1007021 Reflow actor should show reflows in all frames

45 Bugs fixed by 20 contributors.

Firefox OS Media Recording (cjku)

<Read Only>

• bug 1003712 - [B2G][WebRTC] Fall back to VP8 when H.264 HW codec is in use.
• bug 1020227 - Deadlock in opensl_stream_destroy
• bug 1016184 - [Touch Caret]enable touch caret on B2G
• bug 1015860 - [B2G] We can't use systrace style Gecko Profiler in content process.
• bug 987718 - [Text Selection] Display selection caret based on touch caret

GFX (milan)

• OMTC
  • Still enabled on Windows (in Aurora 32 now), but we will turn it off (in Aurora) by June 20th if we don't sort out some performance and correctness regressions
  • Linux getting close to landing
• Tiling on desktop
  • Starting to plan for this work, as it needs to coordinate with APZ. Likely >34.
• APZ
  • 32 (2.0) features in the bag, some usability tweaks left, some correctness bugs being fixed
  • coordinating with layout team, to deliver multi-layer apz (967844, 1011639)
• Interns
  • Two Toronto bound interns are in Mountain View and San Francisco (starting next week), and staying there, the S.F. one working with the layout team instead (no local mentor)

Seceng (grobinson)

• Pinning AMO (for reals!) bug 1019772
• Certified app default CSP on B2G relaxed to allow inline styles bug 858787
  • Removing inline styles from default certified apps might take a while bug 968907
  • Doesn't change effective security level (because non-spec-compliant parser did not block inline styles by default)
  • Was blocking landing the new parser and removing the old one bug 949533

Roundtable

(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)

• [ReadOnly by :bajaj] The 2.0 Release for FxOS hit the feature landing(FL) milestone on June 9th. Gecko 32 for 2.0 is now on mozilla-aurora and gaia branched to 2.0. Here is our final sprint #3 report : http://bit.ly/1j5b45R
  • Landing Policies for 2.0 are updated here

<Read only beyond this point>

Mailing List Threads

(Threads that are likely to be of interest to engineering from various mailing lists.)

Good Reads

(Links to blog posts, books, videos, etc. that you think will be of interest to others.)
