This brings back some of the changes in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20176/diffs.
We discovered another N+1 that hits Gitaly
TreeEntry via the
RelativeLinkFilter: https://gitlab.com/gitlab-org/gitlab-ce/issues/58657. When a blob is loaded with many relative links,
TreeEntry is called for each link to scan the URI type.
There are multiple paths that hit Gitaly
TreeEntry, and https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/25706 did not cover all
cases. This merge request covers another common use case.
For users using Gitaly on top of NFS, accessing the Git data directly
via Rugged may be faster than going through than Gitaly. This merge request introduces
the feature flag
rugged_commit_tree_entry to activate the Rugged method.
