Notices / Schedule

• We shipped Firefox 6!
  • They sent us a cake
• Migration day is going smoothly so far, still ongoing at time of meeting
  • aurora->beta migration complete
  • central->aurora migration underway, using http://hg.mozilla.org/mozilla-central/rev/41b84b87c816 as the migration changeset (current tip)

Firefox Development

• Paul O’Shannessy landed some pref UI to expose a “load tabs on demand” (AKA bartab) pref for sessionrestore (bug 648683)
• Margaret landed a new blank tab icon (created by Stephen Horlander) (bug 648668)
• Ongoing e10s work:
  • e10s-compat build time flag has browser standing up, but no progress events
  • felipe is working on having the WPL listeners work (bug 666801)
  • coming week we’re going to be filing some additional bugs and directing fx-team’s full attention to them (bug fxe10s)

Firefox Developer Tools

Performance

• Telemetry will soon be opt-out (rather than opt-in) on development channels.
  • To opt out in automated-testing profiles, set toolkit.telemetry.enabled = false

GFX

• The Cairo update looks like it’s going to stick despite the regressions, mostly due to the benefits mobile got from it. Please let us know if that’s a bad choice.
• bug 660264 – Tp4 regression due to D3D9-accelerated layers – we’re still working through the issues here, but we believe that this doesn’t actually affect users. Please see that bug for more discussion.
• For more details, see this week’s graphics meeting notes.

JS

Layout

DOM

• Landed William’s patch to add File, Blob and FileReaderSync support to workers. This means that pages and addons can read files off the main thread. bug 664783

WebAPI

Network

• Steve Workman has joined the networking group full-time, working out of Mountain View. Steve comes from Cisco.
• Work on SPDY support coming along. Patrick McManus has posted two discussions to mozilla.dev.tech.network:
  • TLS Next Protocol Negotiation integration for SPDY
  • SPDY::HTTP dataflow – a first sketch

Plugins

Mobile

• Jim Chen (badass intern!) found the cause of long standing Tegra crash bug bug 662936 while running many of the Talos tests.
• Master Password landed

Accessibility

Multi-Process

Tree Management

• Planned tree closure today for network work
• Currently having unplanned tree closure due to tinderbox backlog bug 676822
  • Can try using http://tbpl.allizom.org/?usebuildbot=1 as an alternative
  • IT is currently shuffling storage around to try and get us on faster spindles
  • Other options we’re looking at:
    • delete data from old builds (especially try builds) – reduces volume to migrate
    • cut some trees and setup separate tinderbox instance for some branches on separate dedicated RelEng machines
    • stop sending emails for certain branches – disruptive to developers. try ?
    • extended downtime to speed up the migration of data
    • wait for webdev/IT to get new TBPL to be deployed (will take a long time!)
      • last meeting was with/laura, IT on friday; code already sec-reviewed.
      • mongodb deployment worries
      • more time to revisit after today(tuesday) releases – bunch of work blocking ship FF6.0.

Stability Report

Desktop

Socorro

• Socorro 2.2 released over the weekend.
• Top crashes and crashes per user now split between individual Betas and Release.
• A couple of data query issues introduced: Bug 679182 and Bug 679229.
• Bugs are fixed in staging but no ETA on deployment to production.
  • Update: deployed this morning [laura]

Trunk 8.0a1

• Trunk is a bit unstable – 4.0 crashes per 100 ADU.
• A number of crash regressions on 8.0 – looks as though many of these will be promoted to Aurora so we will be tracking them.
• Bug 679030
• Bug 679035
• Bug 678181 – Causing a number of Font crash signatures. Backed out the patches for Bug 668813 – Need a couple more days to figure out if got rid of all the crashes.
• Spike in old signature which looks related to a certificate change Bug 678710
• Bug 677273

Aurora & Beta

• On top of 7.0 issues.
• Better data after 7.0b1 goes out.

Other

• Shockwave issue emerging across all versions Bug 679148
• Added a new keyword[needs-URLs] to indicate that we need to run a query to see if there is any site correlations to crashes. The crash team can query on this and make sure we have reports for these bugs.

Mobile

• Bug 679065 – Some Fennec 6.0b6 topcrash signatures return an empty report list
• Still missing sympbols for a number of crashes (no signatures). There is an open bug on this Bug 644510
• https://wiki.mozilla.org/index.php?title=QA/Fennec/crash_rep_15Aug2011

Roundtable

• discuss use of purify/sm-purify01 and disposition of license and hardware. /bc
• Hiring a power measurement engineer: if you know of someone, please link them to the job posting and encourage them to apply.
