Bugzilla
Fragment of a discussion from Talk:Gerrit/Advanced usage
Note that Mer Project's Bugzilla has a workflow with an additional step that might help clarifying things: RESOLVED FIXED (patch merged/committed to codebase) -> RELEASED (fix included in tarball) -> VERIFIED (reporter checked that commit actually fixed the issue). Bugzilla4 allows custom workflows in its settings. I agree that the Gerrit commit link should be more advertised. Adding "gerrit <changenumber>" currently is not too helpful as that is not even automatically turned into a direct link (compared to "bug <bugid>").
