[rdo-list] automatically finding RHBZs during rebases

We're using Bugzilla's "External Trackers" a lot in the RH Ceph Storage product and it really helps to correlate RHBZs to upstream releases. I have a quick-and-dirty Python script that looks up the GitHub pull request IDs between Git tags and queries Bugzilla for these. This lets me know which BZs to use in any new RPM version bumps. https://github.com/ktdreyer/find-bzs I'm thinking about how to integrate this into "rdopkg new-version" so that it is seamless. Maybe something like this: "rdopkg new-version" -> determine if upstream is a GitHub project or another (not sure here) -> git log --merges <old-version> <new-version> -> Analyze the Github Pull request numbers from the Git log -> Search for those PRs in Bugzilla -> Assemble a list of rhbz numbers from those PRs -> Insert these rhbz numbers into %changelog extensively as well, although I'm not super familiar with the best way to tie all the data points together. Something like openstack.org Gerrit change IDs -> BZs? Or does it have to go through Launchpad? We could make rdopkg pick the right heuristic depending on the Git remote URL pattern. What do you think? - Ken
