Agreed and agreed.

You can't really compare Jenkins with Zuul as they're designed to
achieve different goals.

Jenkins provides rich tracking of tests, code coverage and code
quality (eg: cppcheck) in addition to checking if it builds.
Zuul is designed to determine if it builds and if tests fail -
providing a binary pass/fail response.
Harbormaster at this point at least looks like it will be similar in
nature to Zuul.

I'll also note that Jenkins provides scheduling and can bring nodes up
and down as needed (when equipped with access to a cloud/cluster).
For this reason Openstack is still relying on Jenkins in part as Zuul
can't do this.

Jenkins also permits us to track jobs unrelated to our code reviews,
which is necessary for
Hmm? It has a description section on tasks. See for an example.
This can also be freely edited.

I'm not aware of any threaded discussion issue tracker, but i'm happy
to be corrected.

It is mainly intended as a task tracker rather than a bug tracker I
believe, hence this position.
The more suitable item to compare it to would therefore be

I concur here that pre-integration is void if the pre-integrated
components aren't useful.

For those that are worried - people have integrated JIRA and
Phabricator together, so it is more than possible to connect
Phabricator with external task trackers.

Please recall that no change of bug tracker or CI system is being
planned at this time - such a change would be for future discussion.
