Performance

GFX

• Graphics BugKill day was last Friday, October 7, 2011.
  • We closed 308 bugs out of the 493 total we touched - about 63% close rate. (There were bugs we didn't touch but did open; thus this is a maximum.)
  • Anecdotal "evidence" says that older bugs were closed with a higher frequency than newer bugs.
  • We found some patches that had languished for 4+ years, many without review requests (i.e., a failure on our part to notice them).
  • We found other bugs that had languished for a long time for no good reason, and created patches for them.
  • Still TBD: where we go from here for our remaining 2000+ bugs.

DOM

• New DOM bindings for NodeList and friends landed! (peterv, bug 648801)

- What else is in being worked on at the front-end: session restore, context-menu, spellchecker menu, network prioritizer, back/forward history, panorama. See details at https://bugzilla.mozilla.org/show_bug.cgi?id=fxe10s

Tree Management

• Rev3 -> Rev4 Snow Leopard update:
  • Testing new r4 machines in parallel. There are 64 machines in production, hidden on tbpl. Can see test/talos results by adding '&noignore=1' to tbpl.
