# RepositoryArchiveCleanUpService removes cached repository archives
# that are generated on-the-fly by Gitaly. These files are stored in the
# following form (as defined in lib/gitlab/git/repository.rb) and served
# by GitLab Workhorse:
#
# /path/to/repository/downloads/project-N/sha/@v2/archive.format
#
# Legacy paths omit the @v2 prefix.
#
# For example:
#
# /var/opt/gitlab/gitlab-rails/shared/cache/archive/project-1/master/@v2/archive.zip
