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|durddt|D}|_fdd|D_|_|_dS)NcSs i|]\}}|dr||qS)Zsocket_) startswith).0kvrrr s z%Sentinel.__init__..cs$g|]\}}t||fijqSr)rsentinel_kwargs)rJhostnamer r0rr sz%Sentinel.__init__..)r rN sentinelsmin_other_sentinelsr6)rrQrRrNr6rr0rrs zSentinel.__init__cCsJg}|jD]&}|d|jjd|jjdfq dt|jd|fS)Nz%s:%srr z%s,)rQappendrr6rrjoin)rZsentinel_addressessentinelrrrr#s   zSentinel.__repr__cCs2|dr|ds|drdS|d|jkr.dSdS)Nr+is_sdownis_odownFznum-other-sentinelsT)rR)rstaterrrrcheck_master_states zSentinel.check_master_statec Cst|jD]z\}}z |}Wnttfy8Yq Yn0||}|r |||r ||jd|jd<|j|<|d|dfSq td|fdS)z Asks sentinel servers for the Redis master's address corresponding to the service labeled ``service_name``.
