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 sJ|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)rmhostnamer*rCrr sz%Sentinel.__init__..)itemsrq sentinelsmin_other_sentinelsrS_force_master_ip)r#rurvrqforce_master_iprSrrCrr"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)rmsentinelargsr$rrrssz,Sentinel.execute_command..T) rIrPkeysr rcchoicerur{r=gather)r#r~r$rytasksrr}rr{s   zSentinel.execute_commandcCsXg}|jD]}||jjdd|jjdqd|jd|jjdd|dS) Nr):r*r'r(z (sentinels=[,z])>)ruappendrrSr&rjoin)r#sentinel_addressesr|rrrr-s  zSentinel.__repr__staterTr`cCs2|dr |ds |drdS|d|jkrdSdS)Nr8is_sdownis_odownFznum-other-sentinelsT)rv)r#rrTrrrcheck_master_states zSentinel.check_master_statec st}t|jD][\}}z |IdH}Wnttfy4}z||d|WYd}~q d}~ww||}|rd|||rd||jd|jd<|j|<|j durX|j n|d}||dfSq d} t |dkrudd |} t d || ) z Asks sentinel servers for the Redis master's address corresponding to the service labeled ``service_name``.
