能不能替我释疑一下这块的注释

[dev4u]

shadowsocks-rust/crates/shadowsocks-service/src/acl/mod.rs

Lines 479 to 489 in 0e0edda

	/// Default mode
	///
	/// Default behavior for hosts that are not configured
	/// - `true` - Proxied
	/// - `false` - Bypassed
	pub fn is_default_in_proxy_list(&self) -> bool {
	match self.mode {
	Mode::BlackList => true,
	Mode::WhiteList => false,
	}
	}

这块代码按照注释的描述，Mode::BlackList表示当前模式下，默认以代理方式处理请求。Mode::WhiteList则相反，默认以直连处理请求。

shadowsocks-rust/crates/shadowsocks-service/src/acl/mod.rs

Lines 30 to 35 in 0e0edda

	pub enum Mode {
	/// BlackList mode, rejects or bypasses all requests by default
	BlackList,
	/// WhiteList mode, accepts or proxies all requests by default
	WhiteList,
	}

但是在Mode的定义里，代码描述的注释却是与上面的逻辑是相反的：Mode::BlackList默认直连，Mode::WhiteList默认代理。

这块我搞不明白要怎么理解，能不能给我解释一下呢？

If mode is BlackList, then domains that are configured should be bypassed. So, the others are “defaults” to be in proxied list.

[dev4u]

在sslocal下，按照你的解释，上下两段代码对blacklist的逻辑是不统一。
你说的blacklist对应的acl是proxy_all模式，

但是在代码上的注释却是:BlackList mode, rejects or bypasses all requests by default，这个应该是bypass_all模式才对。

proxy_all is WhiteList.

感谢解答，我会继续走读代码。

请教一下，我这边想实现sslocal<->ssserver之间的pingpong交互，有了这个交互，两边的应用可以实现数据交换。
这个逻辑我可以从哪里入手呢？

[zonyitoo]

Add a protocol header in the client and server implementation in the shadowsocks crate.

[dev4u]

好的，我去看看。

能不能提供一个工具，可以让我测试手机在不同基站、或者不同网络内漫游切换的时候，有没发生访问不到网络的情况发生？
