(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

Stability

The Need To Know

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

Notices/Schedule (akeybl/lsblakk/bajaj)

?? bugs (?? bugs last week)	?? bugs (?? bugs last week)
Unresolved Aurora 54 Trackers (non-security, not tracked for Beta)	Unresolved Beta 128 Trackers (non-security)

Build Changes (gps)

(Build changes of which engineers should be aware.)

Upcoming Outages/Upgrades

(System outages/upgrades and tree closures that impact engineering.)

Key Issues

(Non team specific issues that impact engineering.)

• (joduinn) In July, 7,051 checkins, with peak day being 02jul having 370 checkins. More details [ http://oduinn.com/blog/2013/08/05/infrastructure-load-for-july-2013/ ]
  • if you know of any builds/tests that are being run-while-hidden.... or that are being run-but-no-longer-needed, please file bug in RelEng or let me know.
  • please use TryServer responsibly. Its there to make developer life better, so people land better quality, better tested patches. But ask yourself questions if you end up at the top of this list. https://secure.pub.build.mozilla.org/builddata/reports/reportor/daily/highscores/highscores.html. Be careful with "-p all"!

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.)

Add-on SDK (dtownsend)

• Prepping a 1.15 SDK release
• All tests passing on Fennec!
• Working on getting automation spun up for Fennec

App Tools (dtownsend)

• Talks with releng about managing simulator builds
• App manager is progressing at pace

GFX (milan)

<Read Only>

• Regions performance improvements (reflow test from 8 to 2 minutes, after regressing to 40 minutes)
• Gradient performance improvements
• Debugging: better layer borders displays, chrome only paint flashing

Media (jesup)

• IETF meeting in Berlin went very well, and two LONG running discussions/disputes were resolved:
  • The most secure option for encrypting media, DTLS-SRTP, remains the only encryption mechanism mandated (MUST implement), and the alternative (SDES) was turned down with a MUST NOT implement.
  • The "Unified plan" developed by abr (Adam Roach), Justin Uberti of Google, and Martin Thompson of Microsoft was adopted as the framework to deal with multiple streams
  • DataChannels moved forward towards finishing the spec; Chrome will be implementing the spec version RSN
  • Opus was highlighted in the Technical Plenary; lots of positive feedback. Congrats to Tim, Jean-Marc, Rillian and the rest of the Opus team

• Gonk audio getUserMedia support landed: bug 825112
• Android WebRTC support is now in Beta

• Top work items are unchanged from last week (latency, performance & video performance, dogfooding)

Quality Programs

(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)

MemShrink (njn)

No update.

Roundtable

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

<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.)
