Subject: Sentinel: when leader in wait-start, sense another leader as race.
X-Git-Url: https://git.saurik.com/redis.git/commitdiff_plain/fd92b366b0ebe325a2c39e66fecdc2f1cbda6936?hp=fd92b366b0ebe325a2c39e66fecdc2f1cbda6936

Sentinel: when leader in wait-start, sense another leader as race.

When we are in wait start, if another leader (or any other external
entity) turns a slave into a master, abort the failover, and detect it
as an observer.

Note that the wait-start state is mainly there for this reason but the
abort was yet not implemented.

This adds a new sentinel event -failover-abort-race.
