Our current code review and continuous integration stack is built on Gerrit, Buildbot, and Bugzilla. It works well enough, but there is certainly room for improvement. Bugzilla and Buildbot in particular are showing their respective ages.
One suggestion that has been popping up recently, both at SharkFest and in private emails, has been to migrate to GitLab. GitLab provides a cohesive interface for all of the things we currently do with separate products: code reviews, continuous integration, issue tracking, and a wiki. I will post answers in favor of Gerrit, GitLab, and other options below. Please add votes, comments, and other options as needed.
If we do decide to migrate it probably won't happen immediately. There are a lot of moving parts which in turn require careful planning and preparation.
