Merge requests merged outside GitLab should self-resolve
Problem to solve
Merge requests that are obsolete because they have been merged already should auto-close
Further details
Samba is slowly moving to GitLab, but for now while we accept merge requests, these are not merged with the UI, but offline via a git push to our master repository (after further automated testing). The patches are rebased and fast-forwarded onto the (eg master) branch.
This means that Samba developers need to manually update merge requests with the details of where they ended up, and close them.
eg samba-team/samba!55 (closed)
This seems a good job for a computer, particularly as ability to merge is being checked each time master is updated.
Proposal
Automatically include text showing when the patch appears to have been merged, and close the request as resolved.
What does success look like, and how can we measure that?
Offline rebase merges of patches trigger the closure of issues without human intervention.
