QA

• First build last week where smoketests were all green!

• Detailed report: https://intranet.mozilla.org/Program_Management/Firefox_OS/WeeklyStatus/20121207#Quality

Firefox Desktop

Social

• Multi-provider support landed on inbound last night. Keep an eye out for any related issues in tomorrow’s Nightly. We’re going to see what the feedback is like before considering an uplift to Aurora 19.

Download Panel

• Much of the work is complete, still some polish bugs to sort out. Primary remaining blocker is the new library downloads view, the team is on it.

Performance

• bug 760036 bounced because of mobile issues (underlying bug seems to be bug 772672). We’ll need a workaround for mobile if fixing that bug can’t happen soon.

Per-window private browsing

• bug 818732 per-window private browsing is almost here. Please help us test this when it gets turned on (will be in a few days.)

Firefox Mobile

Responsiveness and Usability

• bug 811825 : Reflow on zoom should have no effect on constrained height frames.

Stability Wins

• bug 735399 – Only do session restore after a crash
• bug 816902 – java.lang.NullPointerException: at org.mozilla.gecko.AllPagesTab.setSuggestionsEnabled(AllPagesTab.java)
• bug 812867 – java.lang.IllegalArgumentException: width must be > 0 at android.graphics.Bitmap.checkWidthHeight(Bitmap.java)
• java.lang.NullPointerException: Layout parameters cannot be null at android.view.View.setLayoutParams(View.java)

In Progress

• WebRTC
  • https://webrtc-apps.etherpad.mozilla.org/4
  • WebRTC bugs, code now all compiles and links.
  • Some landed, reviews for the rest pending.
• Reflow on Zoom work is ongoing

Metro [Weekly]

Elm to mc merge

• Working on Elm test failures for non-Windows platforms related to the app/gre split.
• New packager should be on elm this week, may land on mc soonish.
• 7 bugs blocking (+2) bug metro-build w/work TBD
• 5 bugs blocking (+3) bug elm-merge w/work TBD

Rel-eng

• Planning to switch mc to the 8.0 sdk after the next merge on ~2013-01-06 bug 774910

Front-end

• First round of Download Manager work landed.
• Simplified touch event handling landed, plus some follow-up work.
• In progress: top site thumbnails; progress indicators; lots of UI polish

Stability Report [Weekly]

• js::GCMarker::processMarkStackTop is a top signature everywhere, has bug 719114, bug 803018, and bug 817342 filed, would really need some investigation to get progress. We know GC crashes are a hard case, but we can’t just ignore 3-5% of our crashes forever.
• bug 812319 and bug 572011 are crashes related with the fully-JS Yandex Bar add-on, so this (in and aorund Russia) popular extension probably triggers problem in our own code. We need investigation of those.
• bug 799118 and bug 790473 are two more JS crashes that have been spiking on trunk and need investigation.

Mobile

QA investigation help needed… Can any dev can give some ideas?:

• bug 780831 (JB crash in dvm) is still the #1 issue on beta and rising on release, STR would be good, but we have progress on it now.
• bug 782223 (JB crash in tegra libs, mostly Nexus 7) is high on beta as well, also needs STR.

• 17.0 Release top crashes
• 18.0b1 Beta top crashes
• Aurora top crashes
• Nightly top crashes

B2G

• bug 817946 – We seem to corrupt memory somewhere, which leads to pretty useless stacks in crash reports
  • any leads on this would be great
• bug 814078 – Submitting all pending crashes – just landed on trunk, waiting for getting onto beta
• nhirata and marcia working on end to end crash reporting – they will have info by 12/14.

Snappy [Weekly]

• Dec 6 Snappy status

Start-up & Shutdown

• BenWa blogged about Analyzing Shutdown Performance

Tab Strip

• Vlad measured significantly reduced FPS rates during Australis tab animations that is particularly noticeable on weak hardware. Details in bug 738491#c76. More investigation and recommendations for the implementers coming.

Content

• Paulo removed downloads from the main thread (bug 789932)
• Ben Smedberg and Aaron Klotz are looking at detaching the input queue of the main Firefox thread from the plugin-container main thread (Win32). This would address a type of plug-in hang that falls outside the scope of our plug-in hang detection code. (bug 818059)
• Progress on moving local storage off the main thread (bug 807021, bug 600307)
