• Describe the issue
  The mass-rebuild failure script at https://pagure.io/releng/blob/master/f/scripts/find_failures.py which generates https://kojipkgs.fedoraproject.org/mass-rebuild/f29-failures.html makes use of only the first maintainer in the data returned by pagure. So the list misses many maintainers, and this has generated a couple of complaints about it not being easy for some people to find packages they need to look at.

There's a script we use when mailing out notices about package problems and mass package changes which lives at https://pagure.io/fedora-misc-package-utilities/blob/master/f/find-package-maintainers. That script generates two lists: one lists packages with a list of maintainers, the other lists maintainers with a list of packages. We find this to be a pretty useful format.

One other thing from our script which would be useful is that it makes use of the cached owner data provided by pagure (at https://src.fedoraproject.org/extras/pagure_owner_alias.json) instead of making an API call per package. This speeds it up, well, a whole lot. That file is updated hourly.

• When do you need this?
  Would be nice to have it before the next mass rebuild, though I guess if we can change it before this one is complete then why not.

• When is this no longer needed or useful?
  I guess it would always be nice to have this.

• If we cannot complete your request, what is the impact?
  Probably just more complaints about packagers not seeing their names in the list when packages they maintain fail to build.
