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|]\}}tf||djqS))r(r))r sentinel_kwargs)rbhostnamer)r>rr sz%Sentinel.__init__..)itemsrf sentinelsmin_other_sentinelsrL)r!rjrkrfrLrr>rr s  zSentinel.__init__csptdd}dkr&d|rRfdd|jD}tj|IdHnt|jj IdHdS)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. onceFcsg|]}t|jqSr)r8ZTaskexecute_command)rbsentinelargsr"rrrhsz,Sentinel.execute_command..NT) rCrIkeysrrjr8ZgatherrYchoicerm)r!rpr"rlZtasksrrorrms   zSentinel.execute_commandcCsNg}|jD](}||jjdd|jjdq |jjdd|dS)Nr(:r)z )rjappendrrLr$rjoin)r!Zsentinel_addressesrnrrrr,s  zSentinel.__repr__)stater'rVcCs2|dr|ds|drdS|d|jkr.dSdS)Nr3is_sdownis_odownFznum-other-sentinelsT)rk)r!rwr'rrrcheck_master_states zSentinel.check_master_state)r'c st|jD]\}}z|IdH}Wnttfk r@Yq YnX||}|r |||r ||jd|jd<|j|<|d|dfSq td|dS)z Asks sentinel servers for the Redis master's address corresponding to the service labeled ``service_name``.
