(Important bugs for which we need to find owners or additional help. If known, please include suggested team or knowledge needed to advance the bug.)
- Orange Factor
- bug 861700 (Intermittent browser_705597.js,browser_707862.js | uncaught exception - [object Event] at undefined:undefined) is #1 top orange and unowned.
- Affects OSX and Windows.
- Possible regression from bug 845681.
- bug 853959 (DrawingContext::DrawBitmap) is an unowned Canvas2D crash that turned into a topcrash across channels apparently due to Apple's iOS7 page.
- We should try to get on this before more similar pages appear with an even higher profile.
- bug 880842 (mozilla::gfx::DrawTargetCG::DrawSurface) is a new unowned trunk topcrash, but the GFX team seems to be on it and have a good suspect for the patch causing it.
The Need To Know
(Release and system issues that may impact engineering this week.)
- FF22b5 will be going to build today/tomorrow, released before the end of the week
- x86 Android audio fix
- Fix for the #1 top Mac crasher
- Only two weeks away from release! Speak now or forever hold your peace :)
- A note on Radeon driver issues, and preventing the loss of .5 million users
|Unresolved Aurora 48 Trackers (non-security, not tracked for Beta)||Unresolved Beta 47 Trackers (non-security)|
(System outages/upgrades and tree closures that impact engineering.)
(Non team specific issues that impact engineering.)
Mike Hoye notes that UCOSP - the Undergraduate Capstone Open Source Project class, a distributed-team last-year project - is moving along, and we have three great submissions for projects so far. If you have other projects that would be suitable for a team of smart kids to work on for a few months in the fall, or any questions, send two or three paragraphs describing them to Mike Hoye at firstname.lastname@example.org.
Quick poke on jst's Embracing git usage for Firefox/Gecko development? thread. If you have thoughts on this subject, please respond this week.
What are the most important problems for the web?
If you have thoughts, contact Anne van Kesteren (annevk) or Andrew Overholt (overholt) on IRC or via email.
(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.)
