> SSH_FXP_REALPATH is used to canonicalizing path on the server side, so
> clients often send path names that do not exist. The procol
> (http://tools.ietf.org/html/draft-ietf-secsh-filexfer-02) clearly states that
> it should respond with dummy attribute values.
> SftpSubsystem class, OTOH, attempts to return actual file attributes, which
> could fail on non-existent paths (or if the path exists but is at the
> location the user doesn't have access to.)
> Handler for SSH_FXP_REALPATH shouldn't attempt to get attributes, or if you
> do, it must recover from errors in SshFile and report dummy values instead.
