Infer the owner of a path based on the owner of its nearest existing parent
constinferOwner=require('infer-owner')inferOwner('/some/cache/folder/file').then(owner=>{// owner is {uid, gid} that should be attached to// the /some/cache/folder/file, based on ownership// of /some/cache/folder, /some/cache, /some, or /,// whichever is the first to exist})// same, but not asyncconstowner=inferOwner.sync('/some/cache/folder/file')// results are cached! to reset the cache (eg, to change// permissions for whatever reason), do this:inferOwner.clearCache()This module endeavors to be as performant as possible. Parallel requests for ownership of the same path will only stat the directories one time.
inferOwner(path) -> Promise<{ uid, gid }>If the path exists, return its uid and gid. If it does not, look to its parent, then its grandparent, and so on.
inferOwner(path) -> { uid, gid }Sync form of
inferOwner(path).inferOwner.clearCache()Delete all cached ownership information and in-flight tracking.
