[ Broadening the audience to include devel@lists.fedoraproject.org ]

Anybody have thoughts about my question below? some examples of places which will need logic like this to replace PDC usage:

ODCS Resolve a module name:stream to a particular build, and do dependency expansion fedmod Get the flatpak-runtime modulemd to find what packages aren't in the runtime and need to be bundled atomic-reactor Load the modulemd for particular module builds to get profile information and figure out what to install in a container flatpak-module-tools Load modulemd and do dependency expansion to build a container locally rpkg Load the modulemd module we are building into a flatpak to find what runtime it is using, and hence the right build target

Thanks! Owen

My understanding is that with the planned retirement of the PDC:

Querying for module information should be done using the MBS and/or Koji APIs.

Various code that I maintain (in OSBS, fedmod, and random tooling) wants to do module build lookups - different variations of "look up the modulemd for latest build of a NAME:STREAM[:VERSION]". Variations generally being exactly what "latest" means here.

The code generally already is using Koji and the MBS api is quite limited, so I've chosen to do the lookups via Koji.

Is a test tool that incorporates most of the capability that I needed across my uses. It's distinctly more than a couple of lines of code - I can cut-and-paste it for now, but what's the right long-term home? Is there a simpler way?

My best idea right now is that if the 'base_version' and'status' part of my code was simplified to simply be "tag" and avoid reliance on the tag structure of Fedora, then this might make a reasonable addition to the Koji CLI and API - there are some things that using raw tags for the query makes trickier, but it's probably workable.

Thanks for any input! Owen
