[GitHub] [incubator-dubbo] kezhenxu94 commented on issue #3180: fixes #2999

["kezhenxu94 (GitHub)" <gi...@apache.org>]

Reviewers please pay special attention to the method `org.apache.dubbo.registry.redis.RedisRegistry.Notifier#notifyListenersOnJedisInstance`, which is extracted from the original `run` method, 
```java
                if (first) {
                    first = false;
                    Set<String> keys = jedis.keys(service);
                    if (keys != null && !keys.isEmpty()) {
                        for (String s : keys) {
                            doNotify(jedis, s);
                        }
                    }
                    resetSkip();
                }
```

the `first` variable is never changed before this patch, if I missed anything, please let me know.
