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.)

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.)

Haida concept (scravag)

Haida is a full concept that aims to propose a radically different user experience in line with the DNA of Mozilla. For overview and dev roadmap please refer to FirefoxOS/Haida.

Firefox OS Communications (scravag)

• Last week was the Oslo Workweek
  • It has been a great workweek. Comms App is a large team that groups Mozilla EU, Mozilla Taipei and Telefonica. Here is the graph of Comms App new features for FxOS 1.2.
    • Conference Call up to 5 participants
    • Contact import / export with merge to USIM, SDCard, via Bluetooth etc...
    • FDN support
    • Basic CDMA support
    • LockScreen redesign
    • Messaging enhancement
    • and more ...
  • 2 user stories remain and will be fixed this week: bug 887534 and bug 911722
• What's next ?
  • Version 1.3 will focus on
    • Messaging completion + some little enhancement
    • [part of Haida] Facebook Contacts move to DataStore
    • Preparing version 1.4 that will support DSDS (Dual SIM)
      • User stories need to be consistent
      • UX must make a proposal
      • Platform work should be completed by the end of 1.3 with consistent and tested APIs

Quality Programs

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

MemShrink (njn)

• Timothy Nikkel fixed bug 847223, which means we no longer decode all images in a page when its first loaded. This can make an enormous difference on image-heavy pages -- we have one example where peak RSS dropped from 2,400 MB to 280 MB. On that same page the loading lag dropped from 5 seconds to 1 second. Assuming no problems are found, the constitutes the completion of the #1 item ("Better Foreground Tab Image Handling") on the MemShrink big ticket items list! Generational GC will be the new #1.

• I am in the process of cleaning up the memory reporter infrastructure. One major change that just landed is that nsIMemoryReporter was removed, and nsIMemoryMultiReporter was renamed as nsIMemoryReporter. It's possible that this might break functionality in some add-ons.

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.)
