使用polipo解决webrtc gclient sync失败的问题

问题

在同步webrtc代码，使用gclient sync，如下只给git配置socks5代理总会失败。

[http]

proxy = socks5://127.0.0.1:22222

[https]

proxy = socks5://127.0.0.1:22222

会报如下错误

____

running cipd ensure -log-level error -root /home/xxx/webrtc/webrtc-checkout -ensure-file /tmp/tmpSfax2e.ensure in .

发现是gclient会访问一些被墙掉的网址，需要配置http的全局代理。

解决

使用polipo，将socks5代理转换成全局的http代理。

1.安装polipo

sudo apt-get install polipo

2.配置polipo， vi /etc/polipo/config 添加

socksParentProxy=127.0.0.1:22223

3.重启服务

sudo service polipo restart

4.配置全局http代理

export http_proxy=127.0.0.1:8123

export https_proxy=127.0.0.1:8123

5.这时gclient sync就能成功了
