    • wrapping up bug 577325, making our processing of function definitions conform to ES5+errata
    • also still going on bug 514568 to give strict mode eval its own scope (such evals can't mess with the binding set of the calling code)

Tree Management

  • A few minor announcements about mobile infrastructure:
    • 11 tegras arrived, imaged, powered, racked; not yet setup in masters and still waiting for SDcards.
    • ~15 of 40 n900s imaged. Waiting for all to be in production before we can enable on tryserver


  • Crashes
    • Numbers down a bit over the weekend - under 2000 crashes a day. The users were also down from last week but compared to a similar number of users 2 weeks ago, the crashes numbers are a bit lower.
    • Most topcrashers are logged for beta8.
    • We have a list we will keep an eye on after beta7 is released.
    • A few new ones that were logged today but not high volume.
