Firefox Development

Q3 Goals Redux:

• [DONE] Feature complete Firefox 4
• [AT RISK] Dirty profile startup within 20% of clean profile
• [MISSED] API-Complete, E10s-aware Jetpack

Q4 Goals Preview:

Firefox

• [NEW] Finish Firefox 4 (0 Firefox/Toolkit blockers)
• [CARRY OVER] API-Complete Jetpack
• [NEW] Stand up basic Firefox with Electrolysis

Developer Tools

• [NEW] Finish Firefox 4 developer tools (0 blocking developer tools bugs)
• [NEW] Ensure that Firefox 4 ships with a compatible version of Firebug
• [NEW] Publish a roadmap for integrated developer tools in Firefox, including console, inspection, and js debugging
• [NEW] Develop long term plan for Skywriter maintenance/support

Platform

(there is a team-by-team goals breakdown, as well)

• [DONE] Javascript performance near or even with Chrome 5 on their benchmarks (within 20% on SS, 30% on V8), with substantial wins on our benchmarks. (Windows, in-browser.)
• [DONE] Hardware acceleration of video and other HTML and SVG content, as well as user interface, on by default for compatible hardware on all Tier-1 desktop and mobile platforms.
• [DONE] Fully support the WebGL 1.0 spec, with support turned on by default in a Firefox 4 beta on platforms that support OpenGL or OpenGL ES.
• [MISSED] security: zero reproducible high/crit > 30 days
• [DONE] Support multi-process Fennec.
• [DONE] Support Jetpacks running in separate processes and never blocking the Fennec UI. NOTE: jetpack team hasn't actually integrated this code yet, but it works in small test environments.

GFX

• Proposal: Let OpenGL be turned on on Mac for Beta 7 despite talos regressions.
  • Data: ~90 ms Ts regression that is very hard to impossible to work around (we can't do it asynchronously on a different thread). Proposal: Deal with it in the same way we're dealing with Direct3D 9 Ts regressions, by putting *other* things on a different startup thread.
  • ~6% Tp4 regression (down from ~10%). Proposal: Let it in for now and do everything we can to get it back down.
  • Reasons this is probably OK:
    • We expect this to provide a lot of benefit for some currently quite slow pages.
    • We need more testing for this to be in a position to be releasable for b7.
    • It's just a switch - we can turn it back off.
  • Alternative:
    • Don't release OpenGL support on Mac with Firefox 4.
    • Allow it in post-b7.
• Resolution: Let OpenGL in on OS X for nightlies, and reconvene before beta 7 final to decide if we should keep it on for the beta.
  • Joe to announce this decision as well as talking about the benefits of accelerated layers using OpenGL.

Layout

• people working on blockers
• as of 6:45pm Monday, 169 total blockers (includes layout, editor, widget, audio/video), including 25 ready to land, 14 waiting for review

Content (aka Compartments this week)

• Got through ~90% of Mochitest and identified a couple of wide impact issues
• window.location prototype patch on hand, needs integrating.

JS

• Method JIT blockers coming along. Blocked on OS X 10.5.8 build following merge from mozilla-central change to build configuration.

Tree Management

• New colo now online
  • Moving test machines should be invisible to developers. Slight hit to capacity as machines are in transit.
  • Start bringing more fast builders online in new colo.
  • no downtimes needed

• OSX universal builds - nightly updates disabled, pending fixes from Josh. bug 571367

• gcc-4.5 switchover (take 3!)
  • Ready to try switching over again, has been attempted on try and Taras says there are no unexpected test failures.

• Please use TryChooser 48% of people used TryChooser last week command line syntax generator

Roundtable

• [beltzner] mozilla-central tree status
  • proposal A: tag and branch for beta7 now or soon, re-open mozilla-central to blockers, dual-land remaining 32 bugs. No builds-on-checkin on RELBRANCH.
  • proposal B: keep mozilla-central closed to blockers and topcrash fixes only
  • proposal C: keep mozilla-central closed to blockers, topcrash fixes only, use cedar/maple for beta8/beta+ fixes.
  • background: bugs waiting to land. Either of keyword:checkin-needed or whiteboard:[can land] will get you added.
• [Tomcat] Stability Report
  • Chofmann's list : http://people.mozilla.com/~chofmann/crash-stats/20100927/signature-ranking-4.0b7pre.txt
  • QA (Marcia, Chofmann and me) is making sure we have bugs on file for topcrashes
• Triage beta 7 blockers (sort by ID)
