What did you do before the bug happened? (Steps to reproduce your issue)
# in a new directory,
cd $(mktemp -d)
# initialize a new repository
git init
# fetch a single commit from a remote
git fetch --filter=tree:0 --depth=1 $REMOTE $COMMIT_OID
# create a ref on that remote
git push --no-verify $REMOTE $COMMIT_OID:$REFNAME
What did you expect to happen? (Expected behavior)
I expected this process to complete very, very quickly. We believe
the version where it had been doing so was ~2.37.
What happened instead? (Actual behavior)
The fetch completes nearly instantly as expected. We receive ~200B
from the remote for the commit object itself. What's truly bizarre
is what happens during the push. It starts receiving objects from
the remote! By the end of this process, the local repository is a
whopping ~700MB -- though interestingly only about a tenth of the
full repository size.
This result in particular is strange in context. I would expect to
either see 'almost all' the repository content, 'about half' (we
have two trunks and fetching a single commit would at most fetch one
of them), or 'virtual none at all'. There isn't a straightforward
explanation for why 'one tenth' would make sense.
What's different between what you expected and what actually happened?
Why should git-push ever be fetching objects? This doesn't map well
to my mental model of the relationship between push/fetch.
I would expect the local repository to stay in that 'git init'+200B
range.
