why zk.Connect always return no error even if zk server is down?

[elianka]

i found that zk.Connect return no error when zk server is error or down. i don't know why? i think it should return error when service is unreachable or timeout. `package main

import ( "fmt" "time"

    "github.com/samuel/go-zookeeper/zk"

)

func main() { c, _, err := zk.Connect([]string{"127.0.0.1"}, time.Second) //*10) if err != nil { panic(err) } fmt.Printf("reach here. no error for zk.Connect! But there is no zk service running \n") children, stat, ch, err := c.ChildrenW("/") if err != nil { panic(err) } fmt.Printf("%+v %+v\n", children, stat) e := <-ch fmt.Printf("%+v\n", e) }`

Haven't tried, but my guess is that you should check the returned channel for connection status.
