[GitHub] [dubbo-go] Da-Hong opened a new issue #1322: zk config_center can't listen configurators well
Da-Hong opened a new issue #1322:
URL: https://github.com/apache/dubbo-go/issues/1322
**What happened**:
error log:
zookeeper/listener.go:300 Send remoting event EventTypeAdd fail, path {/dubbo/config/dubbo/xxx.configurators}
then lose listener with /dubbo/config/dubbo/xxx.configurators
when create /dubbo/config/dubbo/temp will trigger the /dubbo/config/dubbo listener then listen /dubbo/config/dubbo/xxx.configurators success
I found the reason:
GetDynamicConfiguration first async listen zk node when DataChange occure, the CacheListener may not init.
Becasue the CacheListener init by subscribe function after.
Maybe short ttl time can help, but not work perfect.
**What you expected to happen**:
listen config file 'xxx.configurators' success
**How to reproduce it (as minimally and precisely as possible)**:
create /dubbo/config/dubbo/xxx.configurators at zk and start client with config_center
**Anything else we need to know?**:
version 1.5.6 use zookeeper with config_center meta_center registry

The "xxx" should be replaced by your application name. For example, "/dubbo/config/dubbo/user-info-client.configurators"

Hi, I run the program according to your comment, but I cannot reproduce the error. May you describe the reproduction method in detail? Or you can leave your contact information for better communication.

What I fix, but not perfect.
```go
// DataChange changes all listeners' event
func (l *CacheListener) DataChange(event remoting.Event) bool {
if event.Content == "" {
//meanings new node
return true
}
key := l.pathToKey(event.Path)
if key != "" {
count := 1
for {
if listeners, ok := l.keyListeners.Load(key); ok {
for listener := range listeners.(map[config_center.ConfigurationListener]struct{}) {
listener.Process(&config_center.ConfigChangeEvent{Key: key, Value: event.Content, ConfigType: event.Action})
}
return true
}
if count > 3 {
break
}
time.Sleep(time.Second * 1)
count = count + 1
}
}
return false
}
```
