ReplicaTopologyProvider can't parse replicas from INFO

[IlyaShatskikh]

Bug Report

ReplicaTopologyProvider can't parse replicas from the info command response.

Current Behavior

Install Redis Master/Replica from Bitnami Helm Chart.

kubectl get pod,svc,statefulset
NAME                         READY   STATUS    RESTARTS   AGE
pod/redis-chart-master-0     1/1     Running   0          56m
pod/redis-chart-replicas-0   1/1     Running   0          56m
pod/redis-chart-replicas-1   1/1     Running   0          53m
pod/redis-client             1/1     Running   0          13m

NAME                           TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE
service/kubernetes             ClusterIP   10.96.0.1        <none>        443/TCP    57m
service/redis-chart-headless   ClusterIP   None             <none>        6379/TCP   56m
service/redis-chart-master     ClusterIP   10.111.112.156   <none>        6379/TCP   56m
service/redis-chart-replicas   ClusterIP   10.97.3.0        <none>        6379/TCP   56m

NAME                                    READY   AGE
statefulset.apps/redis-chart-master     1/1     56m
statefulset.apps/redis-chart-replicas   2/2     56m

I expect lettuce to connect to Master and Replicas to be read from the INFO command.

# Replication
role:master
connected_slaves:2
slave0:ip=redischartreplicas-0.,port=6379,state=online,offset=3675,lag=0
slave1:ip=redis-chart-replicas-1.,port=6379,state=online,offset=3675,lag=0
master_failover_state:no-failover
master_replid:9b5d528bf6aaf92a3e458b0f956c4310fd4bbf9f
master_replid2:0000000000000000000000000000000000000000
master_repl_offset:3675
second_repl_offset:-1
repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:1
repl_backlog_histlen:3675

In ReplicaTopologyProvider.java:137 SLAVE_PATTERN can't match slave because of the name in IP.

Expected behavior/code

Slaves to be parsed as is.

Environment

• Lettuce version(s): 6.1.10.RELEASE
• Redis version: 7.0.10

Possible Solution

Change SLAVE_PATTERN and IP_PATTERN
