Federated Code Hosting
TL;DR — I'd like a source code management system with Fediverse ActivityPub integration.
I've been looking for a self-hosted home for my Mercurial repositories. Systems like Heptapod, a Mercurial fork of GitLab, feel heavy for what will ultimately be a single-user, multi-project instance, hosted on a Raspberry Pi. Sr.ht has emerged as the top contender being simple for small deployments but able to scale up with it's Unix principles of small, composable pieces. It's not yet deployed due to a lack of ARM binaries for systems like Raspberry Pi.
Through my evaluation process, I had the idea of a federated source code management system allowing for ActivityPub publications and subscriptions of source code projects and users. I noticed some developers of open source projects like Bitcoin core posting merge updates on their Fediverse feeds. This informal process could be automated!
While I don't have the time to work on this myself, I've casually contemplated and discussed with some suggestions surfacing like CPub, a “general ActivityPub server built upon Semantic Web ideas”. Ideally, sr.ht would be extended in this direction.
Really, I'm putting the idea out there to see what others think and hopefully inspire someone to built something.
Edit: After posting, Steven Roose pointed out ForgeFed, a project aimed at exactly this purpose. Primarily focused on Git, but Mercurial shouldn't be too much of a departure. Either way, it doesn't currently look ready to deploy for Mercurial.
