Unfortunately, we can't completely remove the ctx from git.Repository, because the CatFileBatch still heavily depends on a parent context. If we remove the Repository ctx, the CatFileBatch will become a mess and create a lot of unnecessary git processes. http://localhost:3000/-/admin/monitor/perftrace * Before: open a repo home, dozens of git processes (duplicate cat-file) * After: only a few (no duplicate cat-file)
