Feature Work

Roundtable Highlights

  • Trunk maintenance
    • Getting too difficult/lots of maintenance to keep open - too much non-libxul build bustages
    • Proposed route for trunk:
      1. Go for the libxul option 2 asap.
        • We know we're going to libxul
        • It will fix the current bustage, and protect us from any more non-libxul versus libxul
        • Support shared builds as a lower priority option - developers can back up to a working version, but tree can remain open.
      2. Let the work that is being done on external API finish
        • because I can see devs, and maybe linux distros, wanting this.
      3. Do some performances tests of internal & external APIs.
      4. Make decision on which to ship with Thunderbird trunk.
