discovery's Issues

3节点下，部分节点中应用addrs地址错误

部署情况：
单节点多实例不是，192.168.115.242:7171,192.168.115.242:7172,192.168.115.242:7173
注册情况：
ins := &naming.Instance{
Zone: "001",
Env: "prod",
AppID: "app01",
Version: "b",
Addrs: []string{
"http://192.168.115.242:8001",
"grpc://192.168.115.242:9001",
},
LastTs: time.Now().Unix(),
Metadata: map[string]string{
"color":"qa",
"weight":"10",
},
}
问题：

部分节点将 "addrs": ["http://192.168.115.242:8001","grpc://192.168.115.242:9001"]变成了 "addrs": ["http://192.168.115.242:8001,grpc://192.168.115.242:9001"]

example_test.go例子请教

example_test.go中，getInstances的Fetch不是循环一直调用的么，我看日志打印差不多也是30秒才会触发一次

请教关于-alsologtostderr 的具体作用。

run

./discovery -conf discovery-example.toml -alsologtostderr

的时候报错：
flag provided but not defined: -alsologtostderr
去掉-alsologtostderr可以执行，想请教这个具体的作用，谢谢。

注册服务被kill掉, discovery依然存在

Linux使用kill -9把服务给kill掉, discovery没有监控到状态变化

[root@izwz9905avpr21bbhvlvuwz cmd]# nohup kratos run >log.log 2>&1 &

if !replication {

请问一下这个replication参数设计出来的目的是什么？结合注册接口逻辑，这个参数默认一直是false

the discovery serv support cluster?

if not support cluster mode, how to the discovery keep ha? 😅 thank U.

go build 的时候发生错误

按照Quick Start 指导进行以下步骤时

cd $GOPATH/src
git clone https://github.com/bilibili/discovery.git
cd discovery/cmd/discovery
go build

在最后一步 go build 发生错误, 报错信息如下:

为什么返回请求数据需要做深拷贝呢？代码中存在多余的new

为什么每次返回请求数据都要new分配内存呢？直接返回新建/查询到的数据不行吗？如：
func (a *App) NewInstance(ni *Instance, latestTime int64) (i *Instance, ok bool) {
i = new(Instance)
a.lock.Lock()
...
*i = *ni
...
}
func (a *App) Cancel(hostname string, latestTime int64) (i *Instance, l int, ok bool) {
i = new(Instance)
oi, ok := a.instances[hostname]
...
*i = *oi
}
且多处返回空数据也会使用new，如此会产生大量gc吧。如：
func (a *App) Renew(hostname string) (i *Instance, ok bool) {
i = new(Instance)
a.lock.Lock()
defer a.lock.Unlock()
oi, ok := a.instances[hostname]
if !ok {
return // i = new(Instance) 应放在此if之后吧？
}
oi.RenewTimestamp = time.Now().UnixNano()
i = copyInstance(oi)
return
}

使用discovery出错

kratos v0.2.1
discovery v1.1.0
调用 resolver.Register(discovery.Builder()) 后出错

block

关于docker 运行discovery 存在问题

使用配置
[httpServer]
addr = "127.0.0.1:7171"
启动docker，服务只能被本地使用，非127.0.0.1 ip 访问被拒绝。
原因是 discovery 启动gin 的时候使用 httpServer.addr 监听. 将会拒绝所有非127.0.0.1 的请求，
容器也无法使用宿主ip 启动gin. 建议添加单独配置指定 gin 端口。
我本地添加新的配置项，测试通过

缺少获取所有的appId的api

没有这个接口无法提供go-micro注册中心的插件实现

type Registry interface {
	Init(...Option) error
	Options() Options
	Register(*Service, ...RegisterOption) error
	Deregister(*Service) error
	GetService(string) ([]*Service, error)
	ListServices() ([]*Service, error)
	Watch(...WatchOption) (Watcher, error)
	String() string
}

优化的计划?

是否有下面优化的计划呢?
1.数据持久化
2.服务集群化
3.poll换成websocket

nodesproc 中只能获取到本zone的node

(d *Discovery) nodesproc 函数中，poll只会去获取本zone的节点信息，这样子更新后会覆盖本地其他zone的节点

自发现的goroutine 没有做退出控制，依赖于main的退出

go d.nodesproc()

func (d *Discovery) nodesproc() {
for {
// 中间无退出控制
// 会产生野生goroutine
}
}

服务反注册不会触发 poll 返回

考虑有两个 discovery client，发生了这样的事件

clientA.Register()
clientB.Polls(ts = 0) => 返回 ts = 1
clientB.Polls(ts = 1)
clientA.Cancel()

第 4 步不会让第 3 步的长轮询返回，第三步的 polls 要等到长轮询超时。

flaky unit test

单元测试偶尔需要 30秒执行。偶尔只需要1秒钟。

discovery集群节点配置文件错误

discovery-example.toml下

同一discovery集群的所有node节点地址，包含本node

nodes = ["127.0.0.1:7171"]应放于最前面。

能否修正module name和import name,以方便go mod使用

统一将 discovery 修改为 github.com/bilibili/discovery

目前需要手动clone,并且使用了 go mod的话,还要自己加 replace,比较麻烦

build error

go build -v
Fetching https://github.com?go-get=1
Parsing meta tags from https://github.com?go-get=1 (status code 200)
can't load package: package github.com/bilibili/kratos: unknown import path "github.com/bilibili/kratos": cannot find module providing package github.com/bilibili/kratos

看来这个项目也是废了

后续是否会开源仪表盘

请问这个出错是怎么发生的，然后应该怎么解决？
