reloader

基于net.TCPListener的无间断重启服务，暴露listener供业务代码扩充

1. 基于HTTP Server通用方法：

package main

import (
    "net/http"
    "github.com/maxyma/reloader"
)

func main(){
    rl := reloader.NewReloader("127.0.0.1:8080")
    if err:=rl.Bind(); err==nil {
        http.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
            w.Write([]byte("Hello, world!\n"))
        })
        rl.HttpServe(&http.Server{})
    }
}

2. socket server用法

package main

import (
    "net/http"
    "github.com/maxyma/reloader"
)

func main(){
    rl := reloader.NewReloader("127.0.0.1:9001")
    if err:=rl.Bind(); err==nil {
        http.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
            w.Write([]byte("Hello, world!\n"))
        })
        http.Serve(rl.GetListener(), nil)
        rl.Wait()
    }
}

3. 重启

$ kill -s HUP ${PID}
