INFO ALL returns an empty string.

[anadion]

INFO ALL returns an empty string.
If you have more then one node at replicaof and execute INFO ALL after CONFIG GET * it returns an empty string.
It affects redis_exporter oliver006/redis_exporter#326

To Reproduce

1. Create a 3 node active-replica cluster

version: '3.5'
services:
  keydb1:
    image: eqalpha/keydb
    container_name: keydb1
    entrypoint: ["keydb-server"]
    command: ["/etc/keydb/redis.conf", "--port", "6379", "--multi-master", "yes", "--active-replica", "yes","--protected-mode", "no", "--bind", "0.0.0.0", "--repl-diskless-sync", "yes", "--replicaof", "keydb2", "6379","--replicaof", "keydb3", "6379"]
  keydb2:
    image: eqalpha/keydb
    container_name: keydb2
    entrypoint: ["keydb-server"]
    command: ["/etc/keydb/redis.conf", "--port", "6379", "--multi-master", "yes", "--active-replica", "yes","--protected-mode", "no", "--bind", "0.0.0.0", "--repl-diskless-sync", "yes", "--replicaof", "keydb1", "6379","--replicaof", "keydb3", "6379"]
  keydb3:
    image: eqalpha/keydb
    container_name: keydb3
    entrypoint: ["keydb-server"]
    command: ["/etc/keydb/redis.conf", "--port", "6379", "--multi-master", "yes", "--active-replica", "yes","--protected-mode", "no", "--bind", "0.0.0.0", "--repl-diskless-sync", "yes", "--replicaof", "keydb1", "6379","--replicaof", "keydb2", "6379"]

2. Connect to one of them docker exec -ti keydb1 keydb-cli
3. Run CONFIG GET *
4. Run INFO ALL

[JohnSully]

The issue isn't with the INFO command, rather config get returns a corrupt response with multimaster. This confuses the CLI program and results in incorrect processing of later commands.

From telnet:

config get replicaof
*2
$9
replicaof
$14
127.0.0.1 6380
$9
replicaof
$14
127.0.0.1 6381

The *2 should be *4 because we return 4 strings.

Fixed in change 5aef606

The new output is:
127.0.0.1:6379> config get replicaof

1. "replicaof"
2. "127.0.0.1 6380"
3. "replicaof"
4. "127.0.0.1 6381"
