  • Continue hacking on proof of concept integration/docker instance(?)

Last week[edit]

  • Continue working on phabricator privilege separation:
    • Done, for the most part
  • Help with scap release as needed
  • Scrum of scrums
  • eat food with family
  • sleep?
  • This took up a significant part of my weekend:
  • Fixed git mirroring errors that I discovered in phabricator's logs - a bunch of repos were deleted from gerrit but left enabled in phabricator.
    • The errors were causing a major slowdown in the queue which affected phabricator's git commit parsing.
    • Will significantly improve import latency.
