Subject Re: [DISCUSS] Addressing Lingering Pull Requests
Date Thu, 01 Feb 2018 15:40:19 GMT
I agree with Andy on the Docker point, I think it could be too high a
barrier for contribution in some cases. However I think we can build
out / extend a "new component" section of the PR template that has
more best practices, recommendations, suggestions.

I like the idea of the reviewer providing a sample template, perhaps
via Gist or something, but that should probably start as a
recommendation and not a requirement. If a reviewer is unfamiliar with
the new component (or its third-party libraries), they can always ask
the author if they have a test flow they can share, and hopefully the
practice will become status quo organically.

Another thing we could add is checkbox(es) around standard efforts
associated with the addition of new components/bundles. Specifically
if you add new NARs, you have to add them to the nifi-assembly POM and
their versions to the top-level POM, not to mention the bundle to the
nifi-nar-bundles POM.
