Yann Rouillard ee3dfef016 Only delete key from redis in-memory cache if present (#35126) ... Fixes #35120 : the redis cache plugin keeps key/value entries in an in-memory cache to avoid hitting the redis database each time. The problem is that a cache entry is only set when a value is get or set but it is always deleted when trying to delete a value. When the --flush-cache ansible-playbook option is used, the redis cache plugin is first asked to remove every entry corresponding to every hostname present in the inventory. As no value as been set/get so far, it then tries to delete an unexisting value from the cache and hence crashes with a KeyError exception.		2018-10-03 11:06:44 -04:00
