Why GitHub? (lemm.ee)
submitted 1 year ago* (last edited 1 year ago) by james@lemm.ee to c/nostupidquestions@lemmy.world

I can't help but notice most (all I've seen anyway) of the federated projects are hosted on GitHub. GitLab is also not federated, but can be self hosted and has at least discussed it.

I am fully aware of my bias for GitLab over GitHub, but I still wonder why is those things? Is there a federated source hosting project?

Btw I appreciate the fediverse and decentralization as much as the next guy, heck I'm even writing software for the fediverse. But I feel like there's a handful of people out there that want to try and apply the fediverse concept to everything. Similar to what happened with Blockchain. Everyone and everything had to be implemented via Blockchain even if it didn't make sense in the end.

IMO though, GitHub is just one "instance" in an already decentralized system. Sure it may be the largest but it's already incredibly simple for me to move and host my code anywhere else. GitHub's instance just happens to provide the best set of tools and features available to me.

But back to my original concerns. Let's assume you have an ActivityPub based git hosting system. For the sake of argument let's assume that there's two instances in this federation today. Let's just call them Hub and Lab....

Say I create an account on Hub and upload my repository there. I then clone it and start working... It gets federated to Lab... But the admin on Lab just decides to push a commit to it directly because reasons... Hub can now do a few things:

  1. They could just de-federate but who knows what will happen to that repo now.
  2. Hub could reject the commit, but now we're in a similar boat, effectively the repo has been forked and you can't really reconcile the histories between the two. Anyone on Lab can't use that repo anymore.
  3. Accept the change. But now I'm stuck with a repo with unauthorized edits.

Similarly if Hub was to go down for whatever reason. Let's assume we have a system in place that effectively prevents the above scenario from happening... If I didn't create an account on Lab prior to Hub going down I now no longer have the authorization to make changes to that repository. I'm now forced to fork my own repository and continue my work from the fork. But all of my users may still be looking for updates to the original repository. Telling everyone about the new location becomes a headache.

There's also issues of how do you handle private repositories? This is something that the fediverse can't solve. So all repos in the fediverse would HAVE to be public.

And yes, if GitHub went down today, I'd have similar issues, but that's why you have backups. And git already has a solution for that outside the fediverse. Long story short, the solutions that the fediverse provides aren't problems that exist for git and it raises additional problems that now have to be solved. Trying to apply the fediverse to git is akin to "a solution in search of a problem", IMHO.
