$ sudo cp ./dae /usr/bin/dae

测试

未更改原有配置的情况下，systemd启动服务正常运行
执行sudo /usr/bin/dae validate -c /etc/dae/config.dae返回值0

修改配置后，systemctl restart dae.service
主要变更的配置

global {
  tcp_check_url: 'https://cp.cloudflare.com'
}
group {
  proxy {
    filter: subtag([redacted]) && name(keyword: '日本', keyword: '新加坡' , keyword: '美国' , keyword: '台湾')
    filter: subtag([redacted]) && name(keyword: '[redacted]')
    filter: subtag([redacted]) && name(keyword: 'AnyPath', keyword: 'PVCC', keyword: '日本', keyword: '新加坡', keyword: 'IPLC' , keyword: 'IEPL') && !name(keyword: '香港', keyword: '印度')
    policy: min_moving_avg
  }
aur {
    filter: subtag([redacted]) && name(keyword: '日本', keyword: '新加坡' , keyword: '美国' , keyword: '台湾')
    filter: subtag([redacted]) && name(keyword: '[redacted]')
	policy: min_moving_avg
    tcp_check_url: 'https://aur.archlinux.org'
  }
}

routing {
  domain(suffix:archlinux.org) -> aur
  fallback: proxy
}

检查日志

level=info msg="Group "aur"'s check option has been override."

且proxy组没有此日志
代理正常运行

内存使用情况

修改配置添加

group {
  steam {
    filter: subtag([redacted]) && name(keyword: '日本', keyword: '新加坡' , keyword: '美国' , keyword: '台湾')
    filter: subtag([redacted]) && name(keyword: '[redacted]')
    policy: min_moving_avg

  }
}
routing {
  domain(suffix:steampowered.com) -> steam
  domain(suffix:steamcommunity.com) -> steam
  domain(suffix:steamserver.net) -> steam
  domain(suffix:steam-chat.com) -> steam
}

重启后内存使用没有显著增加

@mzz2017 @KagurazakaNyaa 应用这个pr后编译基于此版本dae的daed，会导致daed更新订阅出错，无法获取到节点
报错如下

@mzz2017 @KagurazakaNyaa 应用这个pr后编译基于此版本dae的daed，会导致daed更新订阅出错，无法获取到节点 报错如下 https://pastebin.com/RMCGjJad

看了一下报错在 https://github.com/KagurazakaNyaa/dae/blob/d8fad755979e87fdb448eead497a650a18a23cf1/component/outbound/dialer/dialer.go#L101 似乎是打日志的时候引用了空指针
@mzz2017 请确认一下d.Property().Namedialer有这个属性吗，我好像没有找到，也许不应该使用这个字段来在日志中区分dialer？

[mzz2017]

@KagurazakaNyaa 应该是 daed 在 new dialer 的时候没有传入 property，而是传的空指针导致的，要改一下 dae-wing

[wanlce]

@mzz2017
daed 这边报错是因为 option.Log 为 nil

dae/component/outbound/dialer/dialer.go

Line 101 in cec5e71

option.Log.WithField("dialer", d.Property().Name).

[mzz2017]

@wanlce 可否帮忙修一下？
