Looks like the bzr_buildbot.py needs to get updated to work with the new schedulerdb stuff - changes are no longer available as a simple list. While we're at it, it should get merged into Buildbot proper. And tested. And documented.

[dustin]

I'd like to see this done in 0.8.2, but 0.8.3 is fine if that's what it comes to

[dustin]

c.f. #1755, which has a workaround.

Bzr support is currently orphaned, so this is unlikely to be fixed until a Bzr maintainer steps forward.

[tom.prince]

Uniffied diff version

[tom.prince]

patch originally by hsorby

[tom.prince]

Changing to minor, as we don't have a bzr maintainer.

Ticket retargeted after milestone closed
