Wednesday 2023-09-20 13:15 UTC - `gitlab-org/gitlab` broken `master` with rspec system pg14 4/28
UpdateRemoteMirrorService was calling Gitaly's CommitIsAncestor RPC too often.
Workaround: https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/2566
By letting this class bypass Gitaly we unblock the delivery of the CommitIsAncestor RPC. At a future stage we can migrate
UpdateRemoteMirrorService#execute
to Gitaly in its entirety using gitaly-ruby.
