Spork rspec while using redis, raise Redis::InheritedError

If the code excute redis related function, it will raise

Redis::InheritedError: Tried to use a connection from a child process without reconnecting. You need to reconnect to Redis after forking.

when redis connect it will save the spork process.pid as @pid, then redis excute it will check the connect using ensure_connected, which will check by Process.pid != @pid. and these two pids are different, so it raise Redis::InheritedError.

By Google it, 

Resque.after_fork do 
  Resque.redis.client.reconnect
end

and reconnect the redis client every spec

Both of them don't work for me.

Solution

  • After upgrade redis to 2.6.12, the problem resolved.
