Mozilla 2 Meeting Details

  • Wednesdays - 11:00am Pacific, 2:00pm Eastern, 19:00 UTC
  • Mozilla Building S - <script> conference room

Open Action Items


  • ActionMonkey status: JavaScript:ActionMonkey
    • bsmedberg is generating builds for comparative perftests... this got lost, will have it today
  • XPCOMGC status - XPCOMGC
    • I have a tree that runs xpcshell successfully (all the way to quit)... now I'm working on cornering mark bugs with gczeal and then going to start on running the xpcshell unit tests
  • Exception rewrite


  • bsmedberg: XPCOMGC should be running correctly much sooner than April, but estimate is still April for perf-parity.
  • jonas: mmGC will cause issues because many of our classes do lots of work in destructors, which we can't do with mmgc
  • taras has started working on static rewriting for exception code
  • mmGC vs exceptions (priorities, merge conflicts, etc) - both in Moz2 or mmGC only?
