provider 下线后不断重连 #2159

Closed bobtthp closed 1 year ago

bobtthp commented 1 year ago

registryType: service protocol: triple

依赖版本：

require ( dubbo.apache.org/dubbo-go/v3 v3.0.4-rc1 github.com/BurntSushi/toml v1.1.0 // indirect github.com/apache/dubbo-go-hessian2 v1.11.4 github.com/dubbogo/grpc-go v1.42.10 github.com/dubbogo/triple v1.2.2-rc2 github.com/gin-gonic/gin v1.8.1 google.golang.org/protobuf v1.28.1 )

现象： 当完成 consumer 和 provider 启动后， 手动关闭 provider 进程 consumer 会出现不断重连和如下日志打印，即使在启动 provider 也不会停止

问题1: 当 provider 最后一个节点下线，目前老的 invoker 不会被清理

https://github.com/nacos-group/nacos-sdk-go/issues/494 这个issue解决后，nacos 推送空实例列表，从而清理 oldinvoker
