Electrolysis

• Windowed plugins working! Got various flash demos, the testplugin, and youtube working on Windows and Linux
  • parts of NPRuntime being finished up, leaks are hard (bent), need fixes for bug 518924 (cjones), bug 516509 (josh), release builds crashing on Windows (TBD).
  • Need to set up testing infrastructure for multiple processes. Who do I coordinate with? Alice?
• Windowless plugins work on Linux due to some awesome quick hacks by cjones, but are painfully slow. Need the graphics buffering and async drawing from karlt/jeffm.

Tree Management

• We've stopped running unittests as part of the old unittest build+test job ("U" on tbpl). Only running packaged tests now ("M", "E"). These are also on the Firefox-Unittest / Firefox3.6-Unittest waterfalls. bug 507540

• Now also running tests on debug builds, and optimized builds. These show up as other "M", "E" boxes on tbpl, and have "debug" or "opt" in their name.

• Testing of release builds Real Soon Now.

• Soon mochitest test runs will be being split up according to which directory they're in. These will be showing up as, e.g., "Linux mozilla-central test mochitests-1" bug 487689
