[openstack-dev] [fuel][puppet] The state of collaboration: 5 weeks

Dmitry and I chatted some this morning and I'd at least like to address
those issues so that we can resolve them and move on to the other
discussions. I am not speaking for Emilien here, just jumping in as a core
and trying to help resolve some of this.
As Emilien notes, many of us do not work full-time on puppet code, so
sometimes reviews can slip. IRC messages can also be missed especially
during summer months with many of us on vacations. For that reason, Dmitry
and the Fuel team will be bringing reviews to the weekly meeting to call
out ones that need or are overdue for attention. I believe that missed,
overlooked, ignored, or forgotten reviews are not a new issue for an
OpenStack project, but hopefully this solution will work to improve
throughput. This solution applies to anyone who is possibly not getting
enough attention on the review.

Our weekly meeting schedule link is posted by Monday morning and the
meeting takes place Tuesday. Anyone can add to the schedule.
I also agree with both Emilien and Dmitry that I've seen Fuel contributions
increase since the initial conversation here and I hope to see that trend
continue. It will be better for everyone if we can collaborate well.

> Here's what I see in this review:
> a) Fuel team has spent more than a month (since June 11) on trying to land
> b) 2 out of 5 negative reviews are from Fuel team, proving that Fuel
> are not "rubberstamping" each other's commits as was implied by Emilien's
> comments on the TC review above.
> c) There was one patch set that was pushed 3 business days after a negative
> review, all other patch sets (11 total) were pushed no later than next day
> after a negative review.
> All in all, I see great commitment and effort on behalf of Fuel team,
> eventually awarded by a +2 from Michael Chapman.
> On the same day (June 30), Emilien votes -2 for a correction in a comment,
> walks away from the review for good. 18 days and 4 patch sets and 2
> +1's later, the review remains blocked by that -2. Reaching out on
> #puppet-openstack  didn't help, either.

> At the same time, Emilien has commented on the TC review that the only
> he considers reflective of Fuel's contribution to Puppet OpenStack is
> commits. Isn't that a Catch-22 situation, requesting more merged commits
> refusing to merge them?
> When I compare the trends in the number of patch sets pushed by Fuel

> really obvious when comparing both graphs side by side.
> Between May and July, the peak number of patchsets in Puppet OpenStack

> Mirantis jumped up by a factor of 6.75. At the same time, merged commits
> all contributors increased by 2.44 (meaning 30% less patch sets per commit
> in May), for Mirantis the factor is only 2.0 (meaning 3 times as many patch
> sets per commit as in May).

> In fact, this is exactly the situation that I have predicted in the

> Fuel team can commit to reporting bugs and posting patches, Fuel team can

> Looking through the collaboration thread, the only commitment I see is
> Emilien's promise that "if you submit a good patch now, it will land in
> one week or so", and his comment on the TC review: "The end of the thread
> kind of consensus to me and I was pretty happy to see Dmitry was really
> open to
> the discussion".
> Clearly this kind of consensus is not working out, and I think at least one
> reason is that my proposal for Puppet OpenStack developers to take over
> commits was rejected. One way or another, cases like "16 days since the
> patch set that had no negative reviews" that obviously violate the "land
> a week" commitment have to be identified and prioritized. Being on the
> hook to
> take them over if they don't land on time is one way to introduce a
> to make that happen. There could be other ways to address it, for example
> having a review dashboard that highlights stuck reviews (as I proposed in
> same email) would help add some visibility into the problem.
> Please don't get me wrong. In the same reviews I've highlighted above I see
> excellent example of collaboration from Puppet OpenStack team, insightful
> timely comments, and I'm not denying the effort the team spends on
> new contributors flooding in from Fuel. But I don't see how this situation
> be called "no progress" and "reduced contribution from Fuel" when making
> further progress is limited by Puppet OpenStack team's ability to review
> incoming patches much more than by Fuel team's commitment to proposing and
