Blocker Report

Browser / Front End

  • Polish update: Firefox is 60% shiny (+2% change as some were set invalid) pub?key=pMZGKUlD9NOPg4oJGs1CUMw&oid=1&output=image&foo=.png

pub?key=pMZGKUlD9NOPg4oJGs1CUMw&oid=3&output=image&foo=.png

Priority levels:

The polish priority is based on a combination of UI location / frequency / severity.

  • UI location: is the polish issue in the main interface, a secondary interface, or even deeper into our UI?
  • Frequency: how often the user is likely to encounter the issue?
  • Severity: when the user encounters the issue are they even able to notice it?

Here are general descriptions of the levels:

  • P1 - Polish issue that appears in the main window, or is something that the user may encounter several times a day.
  • P2 - Polish issue that is in a secondary interface, occasionally encountered, and is easily identifiable.
  • P3 - Polish issue that is in a secondary interface, occasionally encountered, or is not easily identifiable.
  • P4 - Polish issue that is rarely encountered, and is easily identifiable.
  • P5 - Polish issue that is rarely encountered, and is not easily identifiable.

Security

Goal discussion ongoing: in particular, the security team is going to discuss which aspects of Mozilla need fuzzing.

Jesse and dveditz are going to start looking at the backlog of crash bugs with the intent of reducing the number of open crash bugs by 20%. They will be trying to using a GTD workflow to help track. More details to follow later, see Jesse's blog for a basic outline.

Electrolysis

Multiprocess tabs are very basically working! See cjones' video.

Stage I is almost complete. We're finishing up small tasks so that phase II can begin:

  • sub-protocols and protocol management (cjones)
  • removing the writable string buffers/ldscript/short-whcar hack (??)
  • integrate IPIDL into the build system (bsmedberg)
  • landing the code into the project repository, with basic review and TODOs clearly marked (bsmedberg)
  • working on Windows again (bent)
  • IPIDL and general IPC documentation (cjones)

Phase II is where we can begin parallel hacking of different subsystems. The immediate list:

  • networking (jduell)
  • global history... needs async history (sdwilsh)
  • docshell hookup, session history, and link targeting (bz)
  • preferences (bsmedberg)

Additional items to spin up as we get more comfortable.

Multi-process plugin work needs love. cjones got something hooked up, but the plugins are not drawing, and it needs a lot of fleshing-out (kinetik?)

Tree Management

  • converted almost all the talos slaves from "dedicated" to "pool-of-talos-slaves"
    • reduced/eliminated wait times?
  • when do 4hr downtime for try-talos. details in bug 448047
  • when do downtime for graph server and talos db changes?
  • cleaning out old builds to free up space on ftp.m.o: long-ish discussion about the value of old and very-old builds. beltzner proposes that we do not archive localized nightly builds because they are much less useful for regression testing. Various proposals floated about using S3 or less reliable and therefore cheaper storage to avoid having to delete old builds... please respond to the newsgroup post in dev.builds

Roundtable

  • CSS 2.1 test suite (dbaron) -- the CSS WG is building the testsuite for CSS 2.1, which serves multiple purposes and for the purpose of deciding whether CSS 2.1 is interoperably implemented, will only be counting tests submitted by September. If you have tests you'd like to submit, please contact dbaron or fantasai. The WG has tentatively agreed to accept tests in reftest format in addition to the standard format.
