Right, I think fetching into the right spots is the easy part. Designing the new lookup rules is the tricky part. If you're really interested in the gory details, here's a very old discussion on it: https://public-inbox.org/git/AANLkTi=yfwoaqmhhvlsb1_xmyoe9hhp2yb4h4tqzw...@mail.gmail.com/ I think there may have been some more concrete proposals after that, but that's what I was able to dig up quickly. > That said, actually I just noticed an issue in the “add a > remote.<name>.fetch option to fetch to refs/quarantine then have the > post-fetch hook do the work”: it means if I run `git pull`, then: > 1.

I am starting to come around to the idea that "pre-fetch" might be the best way to do what you want. Not to rewrite refs, but perhaps to simply reject them. In the same way that we allow pre-receive to reject pushed refs (both are, after all, the final check on admitting new history into the repository, just in opposite directions). > So, when thinking about it, I'm back to thinking the proper hook > interface should be the one of the tweak-fetch hook, but its > implementation should make it not go crazy on remote servers.

It really sounds like you just want to be able to reject or not reject the fetch. And that rejecting would be the uncommon case, so it's OK to just abort the whole operation and expect the user to figure it out. -Peff
