Need To Know

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

Notices/Schedule (lsblakk/sylvestre)

Next Merge: July 8, 2024		Next Release: July 9, 2024
Trains
Central: 129	Aurora: 54	Beta: 128	Release: 127

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.)

MemShrink (njn)

• 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.

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.)

Electrolysis (e10s) (blassey)

• If you'd like to test e10s in Nightly, flip the "browser.tabs.remote.autostart" pref to true and restart Nightly.
  • Known issues likely to affect you: https://etherpad.mozilla.org/e10s-known-issues

Firefox OS Devices/Porting (ericchou)

<Read Only>

• Gonk team (led by Thomas Tsai)
  • Team Summary
    • TBD

• Bluetooth (members: Shawn Huang, Ben Tian, Jamin Liu, Jocelyn Liu)
  • We have received many inputs about "Entering Bluetooth page then Settings app crashes", after investigation we found it's a regression of a Gaia change bug 1032071.
  • bug 1060216 - BluetoothAdapter.discovering wouldn't be updated after calling startDisocovery or stopDisocovery - landed (1.4+)
  • bug 1059136 - Expose Adapter Bluetooth Uuids field - landed (1.4+)
  • bug 1060229 - Get/SetProperty DiscoveryTimeout failed due to missing property length - landed (1.4+)
  • bug 1056413 - Pairing devices after cancelling results in unresponsive page - landed (2.0+)
  • bug 929376 - Content process should be able to use API: BluetoothManager.IsConnected() - landed (2.1+)

• Media Playback (members: Bruce Sun, Blake Wu, Star Cheng)
  • bug 1033915 - Integrate MP3FrameParser with MediaCodecReader - r+ (2.1 feat+)
  • bug 1046578 - [Loop] In a call the audio is very low - WIP (2.0+)
  • Blake is co-working with Anthony Jones to make MSE work on Flame. There are still 4 issues need to be resolved.

• Device Storage (members: Alphan Chen, Eden Chuang)
  • Eden Chuang, SW engineer onboard on 9/1, will join this group.
  • The user story of MTP has been verified and closed. Thanks to Alphan and Dave Hylands.
  • TPE QA Alison has started testing MTP on Flame and has filed several issues.

Firefox OS RIL (htsai)

<Read Only>

1. https://wiki.mozilla.org/TPE_RIL_team/2014-09-02

GFX (milan)

• Summary of 34 goals called out on 7/22, with status:
  • Desktop plans for 34:
    • bug 1036457 tracks having OMTC on Windows ride the 34 train - still looking good, and actually riding 33 train.
    • bug 993639 towards full E10S support - a number of the blockers for this meta have been fixed, all by non-Graphics team engineers.
    • bug 1015218 Linux move to GTK3 - done

• • Firefox OS plans for 34:
    • bug 989403 transform: scale(X) not being repainted when assigned to - done
    • bug 967844 support multi-layer APZ controllers - late landing (weekend work by N.Z., on inbound now), may need an uplift.
    • bug 1016539 color related (b&w, invert, contrast) accessibility features - done, but Gaia work has not landed yet.

• • Other active work not locked to 34:
    • bug 996611 Skia for content everywhere (where everywhere excludes D2D) - we believe we have all the bug fixes we want, and the rest of the failing tests will be fuzzed.
    • APZ on desktop - side project, ongoing.
    • tiling on desktop - ongoing, week of 9/22 is the current target for landing "something".
