示例1: makePublishRPUSH
func makePublishRPUSH(conn redis.Conn, key outil.Selector) (publishFn, error) {
if !key.IsConst() {
// TODO: more clever bulk handling batching events with same key
return publishEventsPipeline(conn, "RPUSH"), nil
}
var major, minor int
var versionRaw [][]byte
respRaw, err := conn.Do("INFO")
resp, err := redis.Bytes(respRaw, err)
if err != nil {
return nil, err
}
versionRaw = versionRegex.FindSubmatch(resp)
if versionRaw == nil {
err = errors.New("unable to read redis_version")
return nil, err
}
major, err = strconv.Atoi(string(versionRaw[1]))
if err != nil {
return nil, err
}
minor, err = strconv.Atoi(string(versionRaw[2]))
if err != nil {
return nil, err
}
// Check Redis version number choosing the method
// how RPUSH shall be used. With version 2.4 RPUSH
// can accept multiple values at once turning RPUSH
// into batch like call instead of relying on pipelining.
//
// Versions 1.0 to 2.3 only accept one value being send with
// RPUSH requiring pipelining.
//
// See: http://redis.io/commands/rpush
multiValue := major > 2 || (major == 2 && minor >= 4)
if multiValue {
return publishEventsBulk(conn, key, "RPUSH"), nil
}
return publishEventsPipeline(conn, "RPUSH"), nil
