xsank / easyproxy Goto Github PK

您好，这个工程的主要功能，使用场景还有如何使用的能描述下么，谢谢

TODO:

1. fix govet warnings
2. fix golint warnings

我是用这个来代理连接到svn服务器，比如svn://localhost:9999,启动proxy后，连接不过去，后台还保持了好几个连接到背后的svn服务器，可能是我通过9999端口访问的时候关掉了，
1.但是proxy与svn之间的连接没断开。
2.ctrl+c 关不掉程序
3.svn协议的不行？

Its a bit unclear how to set multpile services and hosts in config file. Can you give example for it. Thx.

func (proxy *EasyProxy) Dispatch(conn net.Conn) {
	if proxy.isBackendAvailable() {
		servers := proxy.data.BackendUrls()
                // 这里不是特别懂，为啥选出这个url呢？
		url := proxy.strategy.Choose(conn.RemoteAddr().String(), servers)
		proxy.transfer(conn, url)
	} else {
		conn.Close()
		log.Println("no backend available now,please check your server!")
	}
}

func (proxy *EasyProxy) transfer(local net.Conn, remote string) {
	remoteConn, err := net.DialTimeout("tcp", remote, DefaultTimeOut*time.Second)
	if err != nil {
		local.Close()
		proxy.Clean(remote)
		log.Println("connect backend err", err)
		return
	}
	sync := make(chan int)
	channel := &structure.Channel{Src: local, Dst: remoteConn}
	go proxy.putChannel(channel)
	go proxy.safeCopy(local, remoteConn, sync)
	go proxy.safeCopy(remoteConn, local, sync)
	go proxy.closeChannel(channel, sync)
}

我的理解，proxy.strategy.Choose 会在backend随机选择一个对应的backend server来做连接，为啥这里strategy是随机的，不是应该和conn对应对应的吗？ 谢谢大佬帮忙解答一下

Both ChannelManager and ProxyData are multi-threads unsafe, so why not protect those append or delete operations to the same slice or map from different goroutines with sync.Mutex?
