The key must be defined in the keyring. If a keyring is specified but a keyname is not, then the key used will be the first key in the keyring. Note that the order of keys in a dictionary is not defined, so applications should supply a keyname when a keyring is used, unless they know the keyring contains only one key. @type keyname: dns.name.Name or string @param keyalgorithm: The TSIG algorithm to use; defaults to dns.tsig.default_algorithm. Constants for TSIG algorithms are defined in dns.tsig, and the currently implemented algorithms are HMAC_MD5, HMAC_SHA1, HMAC_SHA224, HMAC_SHA256, HMAC_SHA384, and HMAC_SHA512. @type keyalgorithm: string t createt force_uniquet algorithmN( t superR t __init__t flagst dnst opcodet to_flagst UPDATEt isinstancet strt unicodet namet from_textt origint rdataclasst zone_rdclasst find_rrsett questiont rdatatypet SOAt Truet Nonet use_tsig( t selft zonet rdclasst keyringt keynamet keyalgorithm( ( s0 /usr/lib64/python2.7/site-packages/dns/update.pyR s ! ! c C sb | d k r | j } n | j � } | j | | | j | j | | t t � } | j | | � d S( s& Add a single RR to the update section.N( R t authorityt coversR R t rdtypeR t add( R R t ttlt rdt deletingt sectionR! t rrset( ( s0 /usr/lib64/python2.7/site-packages/dns/update.pyt _add_rrA s c G s� t | t t f � r- t j j | d � } n t | d t j j � r� xx| D]O } | ro | j | | j � n x* | D]" } | j | | j | d | �qv WqM Wn t | � } t | j d � � } t | d t j j � r*| r� | j | | d j � n x� | D] } | j | | | d | �qWn� | j d � } t | t � r]t j j | � } n | rv| j | | � n xH | D]@ } t j j | j | | | j � } | j | | | d | �q}Wd S( s� Add records.
