Subject: Supporting --depth when cloning from a bundle
Message-ID: <20220216220710.td4vp6mile5m6hjn@meerkat.local>

Hello, all:

It would be pretty handy if it was possible to do shallow clones from a bundle
file. For example, this would be nice for CI environments that first download
a clone.bundle file from a locally cached location, clone from it, and then
fetch any remaining objects from remote.

E.g., in my mind this outta work:

$ wget https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/clone.bundle
$ git clone --depth 1 clone.bundle linux -b master

Right now, this operation succeeds as-is without any errors, but the resulting
git repository isn't actually shallow.

Oh, it would be even awesomer if the bundle files could be used directly with
--reference, e.g.:

$ git clone --reference clone.bundle --dissociate \
  https://git.kernel.org/.../torvalds/linux.git linux

Any reason that can't work?
