Each node is represented by a pair (hostname, port). ``min_other_sentinels`` defined a minimum number of peers for a sentinel. When querying a sentinel, if it doesn't meet this threshold, responses from that sentinel won't be considered valid. ``sentinel_kwargs`` is a dictionary of connection arguments used when connecting to sentinel instances. Any argument that can be passed to a normal Redis connection can be specified here. If ``sentinel_kwargs`` is not specified, any socket_timeout and socket_keepalive options specified in ``connection_kwargs`` will be used. ``connection_kwargs`` are keyword arguments that will be used when establishing a connection to a Redis server. rNc sD|dkrdd|D}|_fdd|D_|_|_dS)NcSs i|]\}}|dr||qS)Zsocket_) startswith).0kvrrr s z%Sentinel.__init__..cs g|]\}}t||fjqSr)rsentinel_kwargs)r]hostnamer"r6rr sz%Sentinel.__init__..)itemsra sentinelsmin_other_sentinelsrR)rrerfrarRrr6rrs  zSentinel.__init__cOs\t|dd}d|kr&|d|r@t|jj||n|jD]}|j||qFdS)z Execute Sentinel command in sentinel nodes. once - If set to True, then execute the resulting command on a single node at random, rather than across the entire sentinel cluster. onceFT)r:rPkeysrrHchoicereexecute_command)rargsrrgsentinelrrrrjs   zSentinel.execute_commandcCs@g}|jD]}|d|jjq t|jdd|dS)Nz {host}:{port}z )reappend format_maprrRrrjoin)rZsentinel_addressesrlrrrr%s   zSentinel.__repr__cCs2|dr|ds|drdS|d|jkr.dSdS)Nr-is_sdownis_odownFznum-other-sentinelsT)rf)rstater rrrcheck_master_states zSentinel.check_master_statec Cst}t|jD]\}}z |}WnBttfk rf}z ||d|WYqW5d}~XYnX||}|r|||r||jd|jd<|j|<|d|dfSqd}t |dkrdd |}t d ||dS) z Asks sentinel servers for the Redis master's address corresponding to the service labeled ``service_name``.
