* Use MirrorID instead of RepoID - Use the MirrorID as index(SQL uses `id` column not the `repo_id`). Passes the Mirror ID's into the Sync functions. * Check for MirrorID == 0 * Fix `StartToMirror` + refactor * Update services/mirror/mirror.go Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
