Instance Method Details

#fetch(node, group) ⇒ Object

Returns the configuration of group/node_name

#fetch is called by Nodes#fetch Nodes#fetch creates a new Output object each time, so we cannot store the repo index in memory. But as we keep the repo index up to date on disk in #update_repo, we can read it from disk instead of rebuilding it each time.

#get_diff(node, group, oid1, oid2) ⇒ Object
