Executive Summary: https://gitlab.com/groups/gitlab-org/-/epics/10981#note_2626477222 Gitaly supports creating SHA256 repositories. However, there are many places in the Rails tests that break with a longer object id (64 vs 40 length object SHA). We need to identify the Rails tests that break because of this and add tests that test for 64 length object SHA if a SHA256 repository is being used. ### NOTE: this is a collection of _known_ issues, the list is not exhaustive.
