Hi, I've been looking into making git-fetch(1) to use a quarantine directory, but I'm a bit stuck on direction. I took git-receive-pack(1) as an example how it uses a quarantine directory. It seems it sets the environment variables $GIT_OBJECT_DIRECTORY and $GIT_ALTERNATE_OBJECT_DIRECTORIES so the real object db is used as an alternative, and a temporary is set as the default. Then a sub-process is spawned to uses these. In case of git-receive-pack(1), it calls git-unpack-objects(1). At the moment git-fetch(1) does not spawn any similar subprocess, so if we want to take the same approach to use the quarantine, we'll need to split up that command. But then we run into another problem as well. git-fetch(1) updates references, and that is something that's not allowed when using a tmp object directory. As far as I can tell from the code, fetching packs and updating refs is heavily intertwined, so I'm not sure this approach is the best way forward. So a few questions: 1) Does it even make sense to make use git-fetch(1) use a quarantine directory? 2) When making git-fetch(1) use a quarantine directory, what is the recommended way to achieve this? Is this by calling a subprocess? Maybe git-fetch-pack(1)? -- Toon
