Hi,

I want to check the uploaded Git LFS objects in the pre-receive hook
of the Git server. Assuming that the Git repository during the upload
process is A.git, my current approach is to create an empty repository
B.git and then use
GIT_ALTERNATE_OBJECT_DIRECTORIES="A.git/objects/tmp_objdir-incoming-**"
followed by executing git -C B.git cat-file --batch-check
--batch-all-objects to obtain the objects being uploaded, then filter
out the LFS objects. This process is very time-consuming, taking
roughly more than 10 seconds. I wonder if there's a simpler method?

I wonder if it's possible to use `git verify-pack --verbose` on the
received packfile.

Best,
Christian.
