** The problem, which has only recently come to light:
** We talked about this for 10 minutes but decided it need its own meeting, [[Platform/InfallibleMalloc]]. Notes have been moved to that meeting's page.
*** We haven't actually made <code>malloc</code> infallible yet. We already made <code>new</code> infallible for Firefox 4, but many data structures (including arrays and strings) can still misbehave on OOM because [https://bugzilla.mozilla.org/show_bug.cgi?id=611123 <code>malloc</code> can still return NULL].
*** Many exploitable OOM bugs are in system libraries rather than Firefox itself. Replacing <code>malloc</code> may be the <em>only</em> way for us to work around all of these bugs.
*** Security researchers have been reporting many OOM bugs lately.
**** We often can't reproduce what they see because we OOM slightly earlier or later.
**** This is a recipe for embarrassment when "old" testcases find "new" bugs, as Alex Miller [https://bugzilla.mozilla.org/buglist.cgi?quicksearch=504342,583077,606714 discovered].
** The plan of record:
*** [https://bugzilla.mozilla.org/show_bug.cgi?id=610823 Fix <code>nsTArray</code>]
** Proposal:
*** [https://bugzilla.mozilla.org/show_bug.cgi?id=611123 Make <code>malloc</code> infallible]
*** Fix too-large-allocation crashes (distinct from OOM), which will be obvious in crash-stats.
**** Will require exposing a fallible malloc somehow
**** May require adding methods or variants to string classes, for example.
** We must run GC and purge caches before giving up or we will have false positive OOMs when tons of memory is not actually live.
*** Need to monitor OS memory pressure and avoid getting close to these false OOMs.
*** This was part of E10s, is it ready for Firefox 4?

Firefox Development

(from our goals):

Firefox

  • [ON TRACK] API-Complete Jetpack
    • Joint with Jetpack team
    • Currently working towards feature-complete beta SDK
  • [ON TRACK] Stand up basic Firefox with Electrolysis

Developer Tools

  • [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

  • 123 betaN, final, and Fennec blockers
  • OpenGL composited layers on Fennec update (jrmuizel)
    • Sort of usable now, patches need to be finished before they can land though.
    • Performance work still to be done.

Layout

  • Blocker count slowly dropping, now 108
    • Many bug fixes in hand
  • Lots of editor/contenteditable fixes have landed (ehsan)
    • Google Docs features that were disabled for Firefox (spreadsheet formula syntax highlighting) will be enabled for Firefox 4

Tree Management

Roundtable

  • Infallible malloc (added to agenda by Jesse)
    • We talked about this for 10 minutes but decided it need its own meeting, Platform/InfallibleMalloc. Notes have been moved to that meeting's page.
  • Crash Update
    • Crashes on trunk down considerably - ~5/100 active users.
    • In pretty good shape for Beta8
    • Any stability risks in remaining beta8 blockers we should be aware of?
  • Don't forget to file bugs when you see problems in nightlies.
