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

Key Issues

(Non team specific issues that impact engineering.)

• overholt: I'm making the guidelines around exposing things to the web "official"
  • watch for "Is this good for the WEB?" (a la Office Space; see relevant clip from movie here) banners in various MozSpaces

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.)

Accessibility (dbolter)

• The main work: Q4 Goals

Add-on SDK (dtownsend)

No update

App Tools (dtownsend)

• App Manager announcement
• Manifest editor has landed, preffed off

B2G Services (dougt)

Developer Tools (robcee)

Light week. Only 33 bugs fixed including App Manager.

• Reflows in Web Console landing bug 926371
• Hoping to get CodeMirror landed for Firefox 27 merge. bug 919709

• Better Error handling and display in the Debugger bug 812764
• Hide Non-enumerable properties in the JSON tab in Network Monitor bug 862344

DOM (jst/dougt)

Firefox Desktop (gavin/dolske)

Firefox Metro (bbondy/jmathies/mbrubeck)

<Read Only>

• Front end polish and bug fixing continues.
• APZC: Kats and botond have come over for a short period to help out on all our of scroll and zoom issues. Lots of bug triage took place last week. Most every bug has been updated (bug 886321). Bug fixing will commence after a work week this week.
• After lots of feedback at the summit, we are seriously considering switching from a separate profile to a shared profile with desktop (bug 924860). Investigation into this is currently taking place. Some key notes:
  • Users would have to chose a default browser mode (metro or desktop) on Win8 and up. Only one mode would be active at a time.
  • Launching the browser from any location (shortcut/tile) would launch into the default mode.
  • Users would be able to switch from one mode to the other within each browser. This would shut down the existing instance and relaunch the other using the same profile.
  • Most everything would be shared, although certain user data sets (most notably bookmarks and prefs) would be kept separate.

If you have any thoughts/feedback on the above please post in the public metro mailing list (metro@mozilla.org), to the tracking bug, or chat with one of us in #windev.

Summaries:

v1.1hd: e.me bugs is finally fixed. need to uplift a few patches. mostly lefts are [POVB]s and visual bugs and left others to handle. v1.2: koi?/+ is on track to be reduced to Zeero next (or next next week)

v1.3:

• Input cursor management: Engineering planning with SC and Phoebe. Maybe at risk depend on what we figured out.
• Camera work: halt. status changed to nice-to-have and wait for UX input
• DSDS: specific bugs created and is being worked on. Will be working on API change assurances first.
• NFC: Still figuring out how Gaia-Gecko should divide the work. Work week coming next week.
• Settings (EAP-SIM/MTP/SD card format): MTP is dropped from v1.3. SD card format is waiting on UX spec. EAP-SIM is waiting on UX spec.
• Tablet: UX spec released and is being worked on. Need to resolve Music app conflict with Media team. E.me have some landing issue too.
• CDMA: tracking. No outstanding issue.
• 3rd-party keyboard support: Working on v1.2 left overs. Some eng. conflicts to be resolved today.

Necko (dougt/jduell)

• For network performance tests, we'll be lobbying for "webpagetest" to be canonical, not tp5
  • motivator: predictive network API ("seer") (bug 881804) seeing 5% speedup on webpagetest "page revisit" example, but causes 6% tp5 regression.
  • expect a post to dev-tree-management soon from Nick Hurley with more info.
  • yes, we should move webpagetest infrastructure out of Bob Clary's basement :)
• Looks like we're finally mopped up all followup bugs from landing off-main OnDataAvailable for image parsing.

• HTTP cache re-write: working on in-memory index.

Performance (vladan)

  • https://support.mozilla.org/en-US/kb/how-to-enable-java-if-its-been-blocked shows the UI
  • https://developer.mozilla.org/en-US/docs/Site_Author_Guide_for_Click-To-Activate_Plugins is something we can reach out to broken sites
