How to fetch blobs from remote or alternate repositories
For CI processes we have repositories that are cloned with "--filter=blob:none". Also we have a repository cache folder that we set via ".git/objects/info/alternates".
When we try to access the blob contend it fails, is there a way to download the blob from the remote repository? For alternates objects I can probably just copy the objects over manually but I would prefer proper lib support.
What I'm looking for is something like https://git-scm.com/docs/partial-clone/2.49.0#_fetching_missing_objects Manly ideas how to custom implement this or an integrated solution when using the lib.
Reproduction steps
Example repo setup:
git init $GITHUB_WORKSPACE/git --bare
git remote add origin [email protected]:${{ github.repository }}.git
echo "/git-cache/${{ github.repository }}.git/objects" >> ./objects/info/alternates
git fetch --no-tags --no-recurse-submodules --filter=blob:none origin ${{ env.DefaultBranch }}
Actual behavior
Depending on function: No valid git object identified by 'sha xxxxxx' exists in the repository.
