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|dur dd|D}|_fdd|D_|_|_dS)NcSs i|] \}}|dr||qS)socket_) startswith).0kvrrr s z%Sentinel.__init__..cs&g|]\}}td||djqS))r+r,r)r sentinel_kwargs)rohostnamer,rFrr sz%Sentinel.__init__..)itemsrs sentinelsmin_other_sentinelsrV)r#rwrxrsrVrrFrr"s   zSentinel.__init__csxtdd}dvrd|r't|jjiIdHdSfdd|jD}tj |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. onceFNcs"g|] }t|jiqSr)r@Taskexecute_command)rosentinelargsr$rrrusz,Sentinel.execute_command..T) rLrSkeysr rechoicerwr{r@gather)r#r~r$rytasksrr}rr{s   zSentinel.execute_commandcCsXg}|jD]}||jjdd|jjdqd|jd|jjdd|dS) Nr+:r,r'r(z (sentinels=[,z])>)rwappendrrVr&rjoin)r#sentinel_addressesr|rrrr0s  zSentinel.__repr__stater*rbcCs2|dr |ds |drdS|d|jkrdSdS)Nr;is_sdownis_odownFznum-other-sentinelsT)rx)r#rr*rrrcheck_master_states zSentinel.check_master_statec st}t|jD]Q\}}z |IdH}Wnttfy4}z||d|WYd}~q d}~ww||}|rZ|||rZ||jd|jd<|j|<|d|dfSq d}t |dkrkdd |}t d ||) z Asks sentinel servers for the Redis master's address corresponding to the service labeled ``service_name``.
