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|]\}}t||fijqSr)rsentinel_kwargs)rjhostnamer%r;rr sz%Sentinel.__init__..)itemsrn sentinelsmin_other_sentinelsr\_force_master_ip)rrrrsrnforce_master_ipr\rr;rrs   zSentinel.__init__cOst|dd}t|dd}|r)t|jj|i|}|r#|gS|r'dSdSg}|jD] }||j|i|q.|r@|St|S)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. onceFreturn_responsesT)rBrrQchoicerrexecute_commandappendall)rargsrrvrwresponse responsessentinelrrrrys  zSentinel.execute_commandcCsNg}|jD] }|d|jjqdt|jdt|jdd|dS)Nz {host}:{port}rr z (sentinels=[,z])>) rrrz format_maprr\r"rrjoin)rsentinel_addressesrrrrr)s  zSentinel.__repr__cCs2|dr |ds |drdS|d|jkrdSdS)Nr2is_sdownis_odownFznum-other-sentinelsT)rs)rstater#rrrcheck_master_state&s zSentinel.check_master_statec Cst}t|jD]X\}}z|}Wnttfy0}z||d|WYd}~qd}~ww||}|r`|||r`||jd|jd<|j|<|j durT|j n|d}||dfSqd} t |dkrqdd |} t d || ) z Asks sentinel servers for the Redis master's address corresponding to the service labeled ``service_name``.
