Switch to fastgit mirror for github site.

function mirror(url)
     return url:gsub("github.com", "hub.fastgit.org")
end

$ xrepo install libpng
> curl https://hub.fastgit.org/glennrp/libpng/archive/v1.6.37.zip -o v1.6.37.zip

I set the pac.lua and excute xmake g --proxy_pac=/home/wang/.xmake/pac.lua, but errors happened.

Are you sure you have updated to the latest dev version? and let me see your pac.lua

[wangzhankun]

No, I'm using xmake 2.5.3. When I try to build xmake on dev branch, I got the following errors:

only run xmake update -s dev

[wangzhankun]

error

Same error happened. But before I set the proxy_pac, I run xrepo install libpng successfully downloading from github.com

pac.lua

function mirror(url)
     return url:gsub("github.com", "hub.fastgit.org")
end

configure

configure
{
    network = public
    theme = default
    proxy_pac = /home/wang/.xmake/pac.lua
}

xmake version

xmake v2.5.3+202104191802(I have execute xmake update -s dev)

你之前是怎么安装的，安装在哪个目录下，给我看下？ 如果之前走 get.sh 脚本装的，应该在 ~/local/xmake 下，xmake update -s dev 才会生效，如果走 make install 装在 /usr/local 下，这个 update 是不生效的。。

你得走完整更新，切到 ~/local/xmake：

xmake update dev
source ~/.xmake/profile

可以自行找下 proxy.lua 对比下 是否跟 dev版本保持一致：https://github.com/xmake-io/xmake/blob/dev/xmake/modules/net/proxy.lua

内容完全一致。

[waruqi]

已经更新过去了？还是不行？/home/wang/.xmake/pac.lua 内容贴我下呢。。

[wangzhankun]

ENV

• OS WSL Ubuntu 20.04

pac.lua

function mirror(url)
     return url:gsub("github.com", "hub.fastgit.org")
end

[waruqi]

既然已经更新了，按理应该可以的，这个就只能你这自己调下了。。比如到 本地 proxy.lua 下，这个位置，自己加点 print 看下 url 是否被正常替换了，，有没有执行进去

xmake/xmake/modules/net/proxy.lua

Lines 82 to 88 in ef17fec

	function mirror(url)
	local proxy_pac = _proxy_pac()
	if proxy_pac and proxy_pac.mirror then
	return proxy_pac.mirror(url)
	end
	return url
	end

[shuike520]

可以测试一下这个,github资源下载很快
~/.xmake/pac.lua
内容如下

function mirror(url)
     return url:gsub("https://github.com/", "https://github.91chi.fun/https://github.com//")
end
