速度都具备极强的竞争力。Vercel 在 2022 年发布 Turbopack 时给出的数据显示：在 3000 个模块的应用上，Turbopack 冷启动约 1.8s,Vite 约 11.4s。需要注意这是 Vercel 一方公布的对比数据，且随版本迭代差距已显著缩小，实际表现建议以本地基准测试为准。\u003c/p\u003e\n\u003cp\u003e随着 Next.js

Redis（需要尽快执行的任务），也可以用数据库（不着急的任务）。\u003c/p\u003e\n\u003cp\u003e8、\u003c/p\u003e\n\u003cp\u003e如果数据的生成速度和读取速度不匹配，经典解决方案就是缓存。\u003c/p\u003e\n\u003cp\u003e缓存的最简单做法，就是把数据保存在内存，否则就使用专门的键值存储软件（比如 Redis 或 Memcached），后者的好处是多个服务器可以共享缓存。\u003c/p\u003e\n\u003cp\u003e初级工程师希望缓存所有内容，而高级工程师希望尽量少用缓存。因为缓存是状态的来源，不可避免需要校验状态和处理状态过期。\u003c/p\u003e\n\u003cp\u003e9、\u003c/p\u003e\n\u003cp\u003e除了缓存和后台作业，大型系统通常还有事件中心，一般用的是 Kafka。\u003c/p\u003e\n\u003cp\u003e事件中心也是一个队列，存放的是\u0026quot;某件事发生了\u0026quot;的消息。比如，用户注册触发了\u0026quot;新帐户创建\u0026quot;事件，该事件就放入事件中心，然后由事件中心去通知订阅该事件的多个服务：发送欢迎电子邮件、设置个人空间等等。\u003c/p\u003e\n\u003cp\u003e事件中心适用于，发送事件的代码不关心其他服务如何处理事件，或者事件量很大且对响应时间不太敏感。\u003c/p\u003e\n\u003cp\u003e不要过度使用事件，很多时候，更简单的做法是让一个服务请求另一个服务的 API。\u003c/p\u003e\n\u003cp\u003e为了便于除错，所有日志最好都放在一起，你可以立即看到另一个服务的响应。\u003c/p\u003e\n\u003cp\u003e10、推拉\u003c/p\u003e\n\u003cp\u003e如果数据需要传送到多处，有拉取（pull）和推送（push）两种选择。\u003c/p\u003e\n\u003cp\u003e一般来说，拉取比较简单（比如大多数网站采用的轮询），推送更节省资源，不需要用户主动请求数据，一旦后端数据发生变化，服务器主动将数据推送给每个客户端。\u003c/p\u003e\n\u003cp\u003e如果你确实需要向100万个客户端提供最新数据（就像 GMail 那样），应该采用推送还是拉取？这要视情况而定。如果采用推送，就要把每次推送放入一个事件队列，并让一大群事件处理器从队列中拉取数据并推送。如果采用拉取，就要部署一堆（比如100台）快速的只读缓存服务器，处理所有读取流量。\u003c/p\u003e\n\u003ch2 id=\"系统架构图\" class=\"headerLink\"\u003e\n \u003ca

\u003ccode\u003eawait\u003c/code\u003e 挂起时，控制权交还回事件循环，它再去处理下一个就绪项。所有协程之所以能在单线程里表现出「并发」的效果，正是因为这个调度中枢不断在它们之间切换。\u003c/p\u003e\n\u003ch2 id=\"python-内置的两种事件循环实现\" class=\"headerLink\"\u003e\n \u003ca

\u003ccode\u003epolaris\u003c/code\u003e 字样，但实际却是使用的北极星插件能力进行的寻址。这种现象的原因是北极星插件替换了 trpc-go 框架中的一些默认组件（服务发现、服务路由、负载均衡）为北极星插件的实现，导致客户端以几乎无感知的形式完成北极星寻址。\u003c/p\u003e\n\u003ch4 id=\"withtarget\"

class=\"header-mark\"\u003e\u003c/a\u003e深拷贝和浅拷贝的区别\u003c/h3\u003e\u003cp\u003e答：浅拷贝：如果在类中没有显式地声明一个拷贝构造函数，那么，编译器将会根据需要生成一个默认的拷贝构造函数，完成对象之间的位拷贝。default memberwise copy即称为浅拷贝。\u003c/p\u003e\n\u003cp\u003e此处需要注意，并非像大多数人认为的“如果class未定义出copy constructor，那么编译器就会为之合成一个执行default memberwise copy语义的copy constructor”。\n通常情况下，只有在default copy constructor被视为trivial时，才会发生上述情况。一个class，如果既没有任何base/member class含有copy constructor，也没有任何virtual base class或 virtual functions，\n它就会被视为trivial。\u003c/p\u003e\n\u003cp\u003e通常情况下，浅拷贝是够用的。\u003c/p\u003e\n\u003cp\u003e深拷贝：然而在某些状况下，类内成员变量需要动态开辟堆内存，如果实行位拷贝，也就是把对象里的值完全复制给另一个对象，如A=B。\u003c/p\u003e\n\u003cp\u003e这时，如果B中有一个成员变量指针已经申请了内存，那A中的那个成员变量也指向同一块内存。如果此时B中执行析构函数释放掉指向那一块堆的指针，这时A内的指针就将成为悬挂指针。\u003c/p\u003e\n\u003cp\u003e因此，这种情况下不能简单地复制指针，而应该复制“资源”，也就是再重新开辟一块同样大小的内存空间。\u003c/p\u003e\n\u003ch2

class=\"header-mark\"\u003e\u003c/a\u003e关于shared_ptr使用需要记住什么？\u003c/h3\u003e\u003cp\u003e总结下来需要注意的大概有下面几点：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e1）、尽量避免使用raw pointer构建shared_ptr，至于原因此处不便于多讲，后续还有讲解\u003c/li\u003e\n\u003cli\u003e2）、shared_ptr使得依据共享生命周期而经行地资源管理进行垃圾回收更为方便\u003c/li\u003e\n\u003cli\u003e3）、shared_ptr对象的大小通常是unique_ptr的两倍，这个差异是由于Control Block导致的，并且shared_ptr的引用计数的操作是原子的，这里的分析也会在后续看到\u003c/li\u003e\n\u003cli\u003e4）、默认的资源销毁是采用delete，但是shared_ptr也支持用户提供deleter，与unique_ptr不同，不同类型的deleter对shared_ptr的类型没有影响。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2

为什么要进行四次挥手？ / 为什么 TCP 建立连接需要三次，而释放连接则需要四次？\u003c/p\u003e\n\u003cp\u003e【答案一】因为 TCP 是全双工模式，客户端请求关闭连接后，客户端向服务端的连接关闭（一二次挥手），服务端继续传输之前没传完的数据给客户端（数据传输），服务端向客户端的连接关闭（三四次挥手）。所以 TCP 释放连接时服务器的 ACK 和 FIN 是分开发送的（中间隔着数据传输），而 TCP 建立连接时服务器的 ACK 和 SYN 是一起发送的（第二次握手），所以 TCP 建立连接需要三次，而释放连接则需要四次。\u003c/p\u003e\n\u003cp\u003e【问题二】为什么 TCP 连接时可以 ACK 和 SYN 一起发送，而释放时则 ACK 和 FIN 分开发送呢？（ACK 和 FIN 分开是指第二次和第三次挥手）\u003c/p\u003e\n\u003cp\u003e【答案二】因为客户端请求释放时，服务器可能还有数据需要传输给客户端，因此服务端要先响应客户端 FIN 请求（服务端发送 ACK），然后数据传输，传输完成后，服务端再提出 FIN 请求（服务端发送 FIN）；而连接时则没有中间的数据传输，因此连接时可以 ACK 和 SYN 一起发送。\u003c/p\u003e\n\u003cp\u003e【问题三】为什么客户端释放最后需要 TIME-WAIT 等待 2MSL 呢？\u003c/p\u003e\n\u003cp\u003e【答案三】\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003e为了保证客户端发送的最后一个 ACK 报文能够到达服务端。若未成功到达，则服务端超时重传

区间；\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e改变敏感度分布\u003c/strong\u003e：线性回归在整个实数域上敏感度一致，而逻辑回归在 $z=0$ 附近敏感（梯度最大），在远离 0 的位置趋于饱和、梯度接近 0。这种特性让模型更加关注分类边界附近，可以提升对极端样本的鲁棒性，但也带来了「饱和区梯度消失」的问题。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"模型形式与-sigmoid-函数二分类\" class=\"headerLink\"\u003e\n \u003ca

函数有几个关键性质：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e值域为 $(0, 1)$，单调递增；\u003c/li\u003e\n\u003cli\u003e当 $z = 0$ 时，$\\sigma(z) = 0.5$；\u003c/li\u003e\n\u003cli\u003e关于点 $(0, 0.5)$ 中心对称；\u003c/li\u003e\n\u003cli\u003e导数有简洁形式：$\\sigma\u0026rsquo;(z) = \\sigma(z),(1 - \\sigma(z))$，这一性质在后面推导梯度时会非常方便。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e由于 $\\sigma(z) = 0.5$ 当且仅当 $z = 0$，所以\u003cstrong\u003e决策边界\u003c/strong\u003e（decision boundary）就是超平面 $\\mathbf{w}^\\top \\mathbf{x} + b = 0$。也就是说，逻辑回归本质上是一个\u003cstrong\u003e线性分类器\u003c/strong\u003e——若希望得到非线性边界，需要先做特征工程（如多项式特征）或换用核方法、神经网络等模型。判别规则通常为：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e若 $\\sigma(z) \\geq 0.5$，预测为正类（label =

并非必须，可以根据精度（precision）/召回（recall）的权衡进行调整，这在样本不均衡时尤其重要。\u003c/p\u003e\n\u003ch2 id=\"损失函数从极大似然到交叉熵\" class=\"headerLink\"\u003e\n \u003ca

"\u003cp\u003e回归（regression）是一类能为一个或多个自变量与因变量之间关系建模的方法。在自然科学和社会科学领域，回归经常用来表示输入与输出之间的关系。\u003c/p\u003e\n\u003cp\u003e线性回归（linear regression）的历史可以追溯到 19 世纪初（最小二乘法由勒让德于 1805 年首次发表），它在回归的各种标准工具中最简单也最流行。线性回归基于几个简单的假设：首先，假设自变量 \u003ccode\u003ex\u003c/code\u003e 与因变量 \u003ccode\u003ey\u003c/code\u003e 之间的关系是线性的，即 \u003ccode\u003ey\u003c/code\u003e 可以表示为 \u003ccode\u003ex\u003c/code\u003e 中元素的加权和，这里通常允许包含观测值的一些噪声；其次，我们假设任何噪声都比较正常，例如噪声服从正态分布。\u003c/p\u003e\n\u003cp\u003e模型参数（model parameters）的求解需要两样东西：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e（1）一种模型质量的度量方式，通常为损失函数（loss function）；\u003c/li\u003e\n\u003cli\u003e（2）一种能够更新模型以提高预测质量的方法，通常包括求解解析解和随机梯度下降（stochastic gradient descent，SGD）两种方式。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"解析解\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e8%a7%a3%e6%9e%90%e8%a7%a3\" class=\"header-mark\"\u003e\u003c/a\u003e解析解\u003c/h2\u003e\u003cp\u003e线性回归刚好是一个很简单的优化问题。与其他大部分模型不同，线性回归的解可以用一个公式简洁地表达出来，这类解叫作解析解（analytical solution）。\u003c/p\u003e\n\u003cp\u003e首先，我们将偏置 \u003ccode\u003eb\u003c/code\u003e 合并到权重 \u003ccode\u003ew\u003c/code\u003e 中，方法是在包含所有参数的矩阵中附加一列。此时预测问题是最小化 ‖y − Xw‖²，这在损失平面上只有一个临界点，且对应于整个区域的损失极小值点。将损失关于 \u003ccode\u003ew\u003c/code\u003e 的导数设为 0，便可得到解析解：\u003c/p\u003e\n\u003cdiv class=\"code-block highlight is-open show-line-numbers tw:group tw:my-2\"\u003e\n \u003cdiv class=\"\n \n tw:flex \n tw:flex-row\n tw:flex-1 \n tw:justify-between

原生并不直接支持蓝绿发布。要在 k8s 中实现蓝绿发布，通常的做法是：部署两个 Deployment 分别作为蓝方和绿方，再通过更新 Service 的 selector(或 Ingress 后端)将其指向新的 Deployment。\u003c/p\u003e\n\u003ch3 id=\"金丝雀发布\" class=\"headerLink\"\u003e\n \u003ca

class=\"header-mark\"\u003e\u003c/a\u003e金丝雀发布\u003c/h3\u003e\u003cp\u003e金丝雀发布的名称来源于一个历史典故：矿工曾利用金丝雀对瓦斯（一氧化碳、甲烷等）等有毒气体极为敏感的特性，将其带入矿井作为早期预警装置。当空气中出现微量有毒气体时，金丝雀会先于人体出现中毒反应，从而为矿工争取宝贵的撤离时间。(注：这一做法在 British Coal 等英国煤矿中大约始于 1900 年前后，直到 1986 年起逐步淘汰，并于 1996 年正式废止。)\u003c/p\u003e\n\u003cp\u003e金丝雀发布（国内常称灰度发布、灰度更新）借鉴了这一思路：先发布一台，或一个小比例（例如 2%）的服务实例，主要用于做流量验证，因此也称为金丝雀（Canary）测试。\u003c/p\u003e\n\u003cp\u003e简单的金丝雀测试一般通过手工验证完成;复杂的金丝雀测试则需要较完善的监控基础设施配合，通过监控指标反馈来观察金丝雀实例的健康状况，作为后续继续发布或回退的依据。如果金丝雀测试通过，则把剩余的 V1 版本全部升级为 V2 版本;如果金丝雀测试失败，则直接回退金丝雀，本次发布失败。\u003c/p\u003e\n\u003cp\u003e在 k8s 中，可以借助 Deployment 的滚动更新策略配合 \u003ccode\u003erollout pause/resume\u003c/code\u003e 机制来实现简易的金丝雀发布，示例如下。\u003c/p\u003e\n\u003cp\u003e将应用

使用setitimer/timer_create/timer_settime API来设置SIGPROF 信号处理器。这个处理器在runtime.SetCPUProfileRate 控制的周期内被触发，默认为100Mz（10ms）。一旦 pprof.StartCPUProfile 被调用，Go runtime 就会在特定的时间间隔产生SIGPROF 信号。内核向应用程序中的一个运行线程发送 SIGPROF 信号。由于 Go 使用非阻塞式 I/O，等待 I/O 的 goroutines 不被计算为运行，Go CPU profiler 不捕获这些。顺便提一下：这是实现 fgprof 的基本原因。fgprof 使用 runtime.GoroutineProfile来获得等待和非等待的 goroutines 的 profile 数据。\u003c/p\u003e\n\u003cp\u003e一旦一个随机运行的goroutine 收到 SIGPROF 信号，它就会被中断，然后信号处理器的程序开始运行。被中断的 goroutine 的堆栈 在这个信号处理器的上下文中被检索出来，然后和当前的 profiler 标签一起被保存到一个无锁的日志结构中（每个捕获的堆栈追踪都可以和一个自定义的标签相关联，你可以用这些标签在以后做过滤）。这个特殊的无锁结构被命名为 profBuf ，它被定义在 runtime/profbuf.go 中，它是一个单一写、单一读的无锁环形缓冲 结构，与这里发表的结构相似。writer 是 profiler 的信号处理器，reader 是一个 goroutine(profileWriter)，定期读取这个缓冲区的数据，并将结果汇总到最终的 hashmap。这个最终的 hashmap 结构被命名为 profMap，并在 runtime/pprof/map.go中定义。PS：goroutine 堆栈信息 ==\u0026gt; sigProfHandler ==write==\u0026gt; profBuf

相较于基于回调的模式的一些好处：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003epromise 允许我们按照自然顺序进行编码。首先，我们运行 loadScript，之后，用 .then 来处理结果。 callback:在调用 loadScript(script, callback) 时，我们必须有一个 callback 函数可供使用。换句话说，在调用 loadScript 之前，我们必须知道如何处理结果。\u003c/li\u003e\n\u003cli\u003epromise:我们可以根据需要，在 promise 上多次调用 .then。每次调用，我们都会在\u0026quot;订阅列表\u0026quot;中添加一个新的\u0026quot;粉丝\u0026quot;，一个新的订阅函数。callback: 只能有一个回调。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e因此，promise 为我们提供了更好的代码流和灵活性。\u003c/p\u003e\n\u003ch2 id=\"promise-链\" class=\"headerLink\"\u003e\n \u003ca href=\"#promise-%e9%93%be\" class=\"header-mark\"\u003e\u003c/a\u003ePromise 链\u003c/h2\u003e\u003cp\u003e我们有一系列的异步任务要一个接一个地执行 —— 例如，加载脚本。我们如何写出更好的代码呢？\u003c/p\u003e\n\u003cp\u003ePromise 提供了一些方案来做到这一点。\u003c/p\u003e\n\u003cp\u003e在本章中，我们将一起学习 promise 链。\u003c/p\u003e\n\u003cp\u003e它看起来就像这样：\u003c/p\u003e\n\u003cdiv class=\"code-block highlight is-closed show-line-numbers tw:group

resolve）。\u003c/li\u003e\n\u003cli\u003e下一个 then (***) 得到了前一个 then

queue）\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003e异步任务需要适当的管理。为此，ECMA 标准规定了一个内部队列 PromiseJobs，通常被称为\u0026quot;微任务队列（microtask queue）\u0026quot;（V8 术语）。\u003c/p\u003e\n\u003cp\u003e如 规范 中所述：\u003c/p\u003e\n\u003cp\u003e队列（queue）是先进先出的：首先进入队列的任务会首先运行。\n只有在 JavaScript 引擎中没有其它任务在运行时，才开始执行任务队列中的任务。\n或者，简单地说，当一个 promise 准备就绪时，它的 .then/catch/finally 处理程序就会被放入队列中：但是它们不会立即被执行。当 JavaScript 引擎执行完当前的代码，它会从队列中获取任务并执行它。\u003c/p\u003e\n\u003cp\u003e这就是为什么在上面那个示例中 \u0026ldquo;code finished\u0026rdquo; 会先显示。\u003c/p\u003e\n\u003cp\u003epromise 的处理程序总是会经过这个内部队列。\u003c/p\u003e\n\u003cp\u003e如果有一个包含多个 .then/catch/finally 的链，那么它们中的每一个都是异步执行的。也就是说，它会首先进入队列，然后在当前代码执行完成并且先前排队的处理程序都完成时才会被执行。\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e如果执行顺序对我们很重要该怎么办？我们怎么才能让 code finished 在 promise done 之后出现呢？\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003e很简单，只需要像下面这样使用 .then 将其放入队列：\u003c/p\u003e\n\u003cdiv class=\"code-block highlight is-open show-line-numbers tw:group tw:my-2\"\u003e\n \u003cdiv

\u003ccode\u003e.catch\u003c/code\u003e，那么我们就会得到一个未处理的 promise error（可以在控制台中查看）。我们可以使用在 \u003ca href=\"info:promise-error-handling\" rel=\"\"\u003einfo:promise-error-handling\u003c/a\u003e 一章中所讲的全局事件处理程序 \u003ccode\u003eunhandledrejection\u003c/code\u003e 来捕获这类 error。\u003c/p\u003e\n\u003cp\u003e```smart header=\u0026quot;\u003ccode\u003easync/await\u003c/code\u003e 和

\u003ccode\u003eawait\u003c/code\u003e 为我们处理了等待。并且我们使用常规的 \u003ccode\u003etry..catch\u003c/code\u003e 而不是 \u003ccode\u003e.catch\u003c/code\u003e。这通常（但不总是）更加方便。\u003c/p\u003e\n\u003cp\u003e但是当我们在代码的顶层时，也就是在所有 \u003ccode\u003easync\u003c/code\u003e 函数之外，我们在语法上就不能使用 \u003ccode\u003eawait\u003c/code\u003e 了，所以这时候通常的做法是添加 \u003ccode\u003e.then/catch\u003c/code\u003e 来处理最终的结果（result）或掉出来的（falling-through）error，例如像上面那个例子中的 \u003ccode\u003e(*)\u003c/code\u003e 行那样。\u003c/p\u003e\n\u003cdiv

台洗衣机。那么洗衣房就相当于 1 个进程，洗衣工就相当于 1 个线程。\u003c/p\u003e\n\u003cp\u003e如果有 10 个洗衣工，就相当于 10 个线程——1 个进程是可以开多线程的，这就是多线程。\u003c/p\u003e\n\n\u003c/blockquote\u003e\u003cp\u003e\u003cstrong\u003e那么协程呢？\u003c/strong\u003e\u003c/p\u003e\n\u003cblockquote\u003e\n \u003cp\u003e先别急。大家都知道洗衣机洗衣服需要等待时间。如果 10 个洗衣工 1 人负责 1 台洗衣机，效率固然会提高，但难道不觉得浪费资源吗？明明 1 个人就能做的事，却要 10 个人来做：只是把衣服放进去、打开开关，剩下就是等衣服洗好再拿出来。\u003c/p\u003e\n\u003cp\u003e就算很多人来洗衣服，1 个人也足以应付了：开好第一台洗衣机，在等待时去开第二台，再开第三台……直到有衣服洗好了，就回来把衣服取出来，接着再取另一台的（哪台先洗好就先取哪台，所以协程是无序的）。这就是计算机里的协程！洗衣机就是被执行的方法。\u003c/p\u003e\n\n\u003c/blockquote\u003e\u003cp\u003e协程，又称微线程。\u003c/p\u003e\n\u003cp\u003e协程的作用是：在执行函数 A 时可以随时中断，转去执行函数 B，然后再中断函数 B、继续执行函数 A（可以自由切换）。\u003c/p\u003e\n\u003cp\u003e但这一过程并不是函数调用，整个过程看起来像多线程，实际上协程只在一个线程中执行。\u003c/p\u003e\n\u003cp\u003e协程很适合处理 I/O 密集型程序的效率问题。协程本质上是单线程，它无法同时利用单个 CPU 的多个核，因此对于 CPU 密集型程序，协程还需要和多进程配合使用。\u003c/p\u003e\n\u003ch2 id=\"可等待对象-await-的使用\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e5%8f%af%e7%ad%89%e5%be%85%e5%af%b9%e8%b1%a1-await-%e7%9a%84%e4%bd%bf%e7%94%a8\"

都被设计为接受可等待对象。\u003c/p\u003e\n\u003cp\u003e可等待对象有三种主要类型：协程、任务 和 Future。\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e协程：Python 中的协程属于可等待对象，因此可以在其他协程中被等待。\u003c/li\u003e\n\u003cli\u003e\u003ccode\u003etime.sleep()\u003c/code\u003e：Python 内置的 \u003ccode\u003esleep\u003c/code\u003e 不是可等待对象，如果在协程中需要睡眠，应使用

\u003ccode\u003eawait\u003c/code\u003e 可以调用另一个 async 函数，这个调用看起来是串行执行的，但实际上由 asyncio 内部的事件循环控制。\u003c/li\u003e\n\u003cli\u003e在一个 async 函数内部，通过 \u003ccode\u003eawait asyncio.gather()\u003c/code\u003e

的协程最大的优势在于它是语言内置的。从内存管理、GC 到网络库、syscall 以及对应的 runtime 实现的 M:N 调度，都做了很深的优化。同时经过多年的积淀，社区也基于内置的协程贡献了大量优秀的开源库，大家都遵循同一个并发模型（也就是 Go 推荐的模型）来编写代码，使用起来很顺手。\u003c/p\u003e\n\u003cp\u003eJS 基于回调的特性可以说是目前语言协程化做得最好的：因为没有阻塞调用，可以无痛地把一个回调风格的 API（如 \u003ccode\u003ereadFile\u003c/code\u003e）包装成 Promise，再供 \u003ccode\u003easync/await\u003c/code\u003e 使用。任何回调风格的第三方库 API 都可以简单地用 \u003ccode\u003eutil.promisify\u003c/code\u003e 变成可 \u003ccode\u003eawait\u003c/code\u003e 的 Promise，而不需要从底层添加 API、并要求所有第三方库跟着改造。而且一个 API 可以同时以回调和 \u003ccode\u003eawait\u003c/code\u003e 两种风格使用，可谓无缝升级。再借助 Babel，如今的 JS 项目已经把 \u003ccode\u003easync/await\u003c/code\u003e 用得飞起。\u003c/p\u003e\n\u003cp\u003e再反过来看很多语言的协程化进程：Python 为所有阻塞 API 在 asyncio 这个包里重新实现了一遍，但社区所有数据库驱动、网络请求库、HTTP server 库都需要为它重写，这个生态能不能火起来还是未知数。\u003c/p\u003e\n\u003cp\u003e现在唯一的期待就是 Rust 尽快从语言标准层面拥抱协程——这事儿语言官方越晚接受，社区就越伤筋动骨。\u003c/p\u003e\n\u003ch2 id=\"相关协程库\" class=\"headerLink\"\u003e\n \u003ca

Asio 是一个网络程序库。\u003c/p\u003e\n\u003cp\u003e需要注意:\u003ccode\u003etcp::socket\u003c/code\u003e 类本身\u003cstrong\u003e不是\u003c/strong\u003e线程安全的。因此，要避免在某个线程里读一个 socket 时，同时在另外一个线程里对同一个 socket 进行写入操作（通常来说，这种并发访问同一对象的做法都不被推荐，在 Boost.Asio 中更应避免）。更准确地说：对同一个 socket 同时发起多个\u003cstrong\u003e同类型\u003c/strong\u003e的未完成异步操作(例如同时有两个 \u003ccode\u003easync_read_some\u003c/code\u003e 未完成)是不安全的;而一个 \u003ccode\u003easync_read\u003c/code\u003e 与一个 \u003ccode\u003easync_write\u003c/code\u003e 同时存在则是允许的。若要避免 handler 之间的竞态，可以使用 \u003ccode\u003estrand\u003c/code\u003e 串行化执行。\u003c/p\u003e\n\u003ch2

class=\"header-mark\"\u003e\u003c/a\u003e思路 1:每个线程一个 io_context\u003c/h3\u003e\u003cp\u003e在多线程的场景下，每个线程都持有一个 \u003ccode\u003eio_context\u003c/code\u003e,并且每个线程都调用各自的 \u003ccode\u003eio_context\u003c/code\u003e 的 \u003ccode\u003erun()\u003c/code\u003e 方法。\u003c/p\u003e\n\u003cp\u003e特点:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e在多核的机器上，这种方案可以充分利用多个 CPU 核心。\u003c/li\u003e\n\u003cli\u003e某个 socket 描述符并不会在多个线程之间共享，所以不需要引入同步机制。\u003c/li\u003e\n\u003cli\u003e在 event handler 中不能执行阻塞的操作，否则将会阻塞掉 \u003ccode\u003eio_context\u003c/code\u003e 所在的线程。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch3 id=\"思路-2多个线程共享一个-io_context\" class=\"headerLink\"\u003e\n \u003ca

io_context\u003c/h3\u003e\u003cp\u003e全局只分配一个 \u003ccode\u003eio_context\u003c/code\u003e,并且让这个 \u003ccode\u003eio_context\u003c/code\u003e 在多个线程之间共享，每个线程都调用全局的 \u003ccode\u003eio_context\u003c/code\u003e 的 \u003ccode\u003erun()\u003c/code\u003e 方法。\u003c/p\u003e\n\u003cp\u003e先分配一个全局 \u003ccode\u003eio_context\u003c/code\u003e,然后开启多个线程，每个线程都调用这个 \u003ccode\u003eio_context\u003c/code\u003e 的 \u003ccode\u003erun()\u003c/code\u003e 方法。这样，当某个异步事件完成时,\u003ccode\u003eio_context\u003c/code\u003e 就会将相应的 event handler 交给任意一个线程去执行。\u003c/p\u003e\n\u003cp\u003e然而这种方案在实际使用中，需要注意一些问题:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e在 event handler 中允许执行阻塞的操作（例如数据库查询操作）。\u003c/li\u003e\n\u003cli\u003e线程数可以大于 CPU 核心数。譬如说，如果需要在 event handler 中执行阻塞的操作，为了提高程序的响应速度，这时就需要提高线程的数目。\u003c/li\u003e\n\u003cli\u003e由于多个线程同时运行事件循环（event loop）,所以会导致一个问题：一个 socket 描述符可能会在多个线程之间共享，容易出现竞态条件（race condition）。譬如说，如果某个 socket 的可读事件很快发生了两次，那么就会出现两个线程同时读同一个 socket 的问题（可以使用 strand 解决这个问题）。\u003c/li\u003e\n\u003cli\u003e无锁的同步方式:Asio 提供了 \u003ccode\u003estrand\u003c/code\u003e(新版推荐使用 \u003ccode\u003emake_strand(io_context)\u003c/code\u003e 或 \u003ccode\u003eio_context::make_strand()\u003c/code\u003e)。如果多个 event handler 通过同一个 strand 对象分发（dispatch）,那么这些 event handler 就会保证顺序地执行，而不会并发。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"调试实践\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e8%b0%83%e8%af%95%e5%ae%9e%e8%b7%b5\"

接口的十余个函数，向程序员暴露出定制协程流程和行为的入口。实现一个最简单的协程，通常需要用到其中的 8 个（5 个 Promise 函数 + 3 个 Awaitable 函数）。下面先从 Awaitable 的 3 个函数说起。\u003c/p\u003e\n\u003cp\u003e如果希望写出形如 \u003ccode\u003eco_await blabla;\u003c/code\u003e 的调用形式，\u003ccode\u003eblabla\u003c/code\u003e 就必须实现 Awaitable。\u003ccode\u003eco_await\u003c/code\u003e 是 C++20 引入的新运算符。Awaitable 主要包含 3 个函数：\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ccode\u003eawait_ready\u003c/code\u003e：返回该 Awaitable 实例是否已经就绪。协程开始时会调用此函数；若返回 \u003ccode\u003etrue\u003c/code\u003e，表示期待的结果已经到手，协程无需挂起，因此大多数场景下它的实现都是 \u003ccode\u003ereturn false\u003c/code\u003e。\u003c/li\u003e\n\u003cli\u003e\u003ccode\u003eawait_suspend\u003c/code\u003e：挂起 awaitable。该函数会传入一个 \u003ccode\u003ecoroutine_handle\u003c/code\u003e 类型的参数，这是由编译器生成的句柄。在此函数中调用 \u003ccode\u003ehandle.resume()\u003c/code\u003e，即可恢复协程。\u003c/li\u003e\n\u003cli\u003e\u003ccode\u003eawait_resume\u003c/code\u003e：当协程被重新唤醒时会调用该函数，其返回值也就是 \u003ccode\u003eco_await\u003c/code\u003e 表达式的返回值。\u003c/li\u003e\n\u003c/ol\u003e\n\u003cp\u003e函数的返回值需要满足 Promise 的规范。最简单的 Promise 如下：\u003c/p\u003e\n\u003cdiv class=\"code-block highlight is-closed show-line-numbers tw:group

id=\"无栈协程原理\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e6%97%a0%e6%a0%88%e5%8d%8f%e7%a8%8b%e5%8e%9f%e7%90%86\" class=\"header-mark\"\u003e\u003c/a\u003e无栈协程原理\u003c/h2\u003e\u003cp\u003e参考某知乎答主的回答，可以从应用倒推原理：\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003e无栈协程既可以只开一个，也可以开几十万个，这说明它依赖动态内存分配，协程的局部变量是分配在堆空间的。\u003c/li\u003e\n\u003cli\u003e无栈协程没有运行时栈，这意味着每个协程必须「知道自己是协程」。举例：当协程 a 引用一个局部变量 \u003ccode\u003elocal_v\u003c/code\u003e 时，需要被编译为类似 \u003ccode\u003e(*a_frame).local_v\u003c/code\u003e 的形式，也就是从协程 a 占有的堆内存中取出 \u003ccode\u003elocal_v\u003c/code\u003e；同一种协程的多个实例之间的堆内存互不相干。\u003c/li\u003e\n\u003cli\u003e当协程 a 调用一个普通函数 b 时，函数 b 并不知道调用者 a 是不是协程，也只需遵循普通的函数调用约定，在栈上开辟栈帧。在概念上，除非函数 b 结束并返回到协程 a，否则协程 a 永远没有机会暂停。\u003c/li\u003e\n\u003cli\u003e当普通函数 b 调用一个协程 c 时，函数 b 同样不需要知道 c 是不是协程。在 C++20 中，普通函数 b 只需调用 \u003ccode\u003ec.resume()\u003c/code\u003e，就好像这是一个普通函数。\u003c/li\u003e\n\u003cli\u003e延续第 4 点，当 \u003ccode\u003ec.resume()\u003c/code\u003e 返回后，协程 c 可能已经结束，也可能只是被挂起了，这不重要。随后你也许希望调用 \u003ccode\u003ed.resume()\u003c/code\u003e、\u003ccode\u003ee.resume()\u003c/code\u003e 等等。实际上普通函数 b 在这里扮演了一个调度者的角色，决定着哪个协程应该运行，此时可将它视为「调度器」。这种「协程暂停 -\u0026gt; 回到调度器 -\u0026gt; 另一个协程运行 -\u0026gt; ……」的循环模式叫做「非对称协程」。另一种模式是「协程暂停 -\u0026gt; 另一个协程运行」，即 \u003ccode\u003ec.resume()\u003c/code\u003e 结束后并没有返回普通函数 b，而是直接切换到另一个协程，叫做「对称协程」。「对称协程」和「非对称协程」可以互相模拟，本质区别不大。\u003c/li\u003e\n\u003c/ol\u003e\n\u003cp\u003e那么，如何用普通函数实现非对称协程？\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003e首先定义一个 \u003ccode\u003estruct Frame\u003c/code\u003e「协程帧」，负责存放协程的局部变量。这样每当新建一个协程时，只需整体分配一次堆空间。显然，由于不同协程内具有不同的局部变量，你需要对每一种协程都定义一个 Frame，于是代码里会出现 \u003ccode\u003eA_Frame\u003c/code\u003e、\u003ccode\u003eB_Frame\u003c/code\u003e、…… 你会觉得这种机械工作太过繁琐，为什么不让编译器来做呢？幸运的是，C++20 的编译器能够帮你准确无误地完成这些工作，真心建议放弃 C++11。\u003c/li\u003e\n\u003cli\u003e堆空间有了，那如何实现「可暂停」？很简单：在每个暂停点直接 \u003ccode\u003ereturn;\u003c/code\u003e 即可。\u003c/li\u003e\n\u003cli\u003e在暂停点 \u003ccode\u003ereturn\u003c/code\u003e 之后，又如何做到「可重入」？用 \u003ccode\u003eswitch case\u003c/code\u003e 手动模拟即可。所以「协程帧」不仅要存放局部变量，还要存放 \u003ccode\u003eswitch case\u003c/code\u003e 所依赖的状态值，用来表示「协程当前执行到哪一步」。\u003c/li\u003e\n\u003cli\u003e协程最终结束后，如何返回值？同样写入协程帧即可。如果调用方需要用到返回值，到协程帧里读取就是了。由此看来，协程结束后不能立即回收协程帧的内存——毕竟调用方还要读取。\u003c/li\u003e\n\u003cli\u003e如果协程内部要抛出异常怎么办？答案还是协程帧！我们强制让每个协程体都被一个 \u003ccode\u003etry-catch\u003c/code\u003e 包裹，当异常发生时将其写入协程帧，然后当作无事发生；只有当调用方查询协程帧时，才会发现并重新抛出这个异常。\u003c/li\u003e\n\u003c/ol\u003e\n\u003cp\u003e至此，你拥有了一个可暂停、可重入、可并发几十万个的普通函数（以及它对应的协程帧结构体），你称之为「协程」。由于每次暂停都是直接 \u003ccode\u003ereturn;\u003c/code\u003e 回到上层调度器，所以它是「非对称的」。不过，协程帧的内存申请与释放时机都需要你非常小心地控制。\u003c/p\u003e\n\u003cp\u003e理解了以上原理，再去阅读 C++20 协程的相关文档，应该会容易许多。\u003c/p\u003e\n\u003ch2 id=\"基于-c20-协程封装的库\"

\u003ccode\u003e500 * 0.1s = 50\u003c/code\u003e。基本在同一个数量级，可用同步；如果未来延时继续增长，考虑异步。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e这个公式计算的是同时进行的平均请求数（即并发数，可以尝试证明一下），和线程数、CPU

核数差不多时，异步能节省的线程资源就很有限了，这时候简单易懂的同步代码更重要。\u003c/li\u003e\n\u003cli\u003e除此之外，还要看具体的业务场景：如果业务会面对大量的短/长连接，M:N 协程的实现性能通常比不上通用线程模型，不太适合。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"参考文档\"

API、同一套存储，将 Registry 当作一个云存储系统。这就催生了 OCI Artifacts 的概念——用户能够把所有产物都存储在兼容 OCI 的 Registry 中并进行分发。为此，Microsoft 将 oras 作为一个客户端实现捐赠给了社区，目前 oras 已是 CNCF（Cloud Native Computing Foundation）项目，包括 Harbor 在内的多个项目都在积极参与。\u003c/p\u003e\n\u003ch3 id=\"oci-仓库\" class=\"headerLink\"\u003e\n \u003ca href=\"#oci-%e4%bb%93%e5%ba%93\" class=\"header-mark\"\u003e\u003c/a\u003eOCI

能够实现「配置即数据」的关键——所有运行期行为都抽象成可热下发的资源，由控制面集中管理。理解 xDS 时，可以从三个层次入手：\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003e资源类型层\u003c/strong\u003e：LDS / RDS / CDS / EDS / SDS

\u003ccode\u003enonce\u003c/code\u003e / ACK / NACK 的可靠性语义；\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e实现层\u003c/strong\u003e：Istio Pilot/ Istiod、Higress、go-control-plane 这些项目是如何把协议落到工程里的。\u003c/li\u003e\n\u003c/ol\u003e\n\u003cp\u003e掌握了这套协议族，无论是阅读 Istio 源码、二次开发服务网格，还是自研一个基于 Envoy 的网关控制面，都会顺畅很多。\u003c/p\u003e\n\u003ch2 id=\"参考\" class=\"headerLink\"\u003e\n \u003ca

HTTP 和 WebSocket 两种协议:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003eWebSocket 接口用于接收任务状态与进度信息(实时推送)。\u003c/li\u003e\n\u003cli\u003eHTTP 接口用于提交任务、查询任务结果、下载生成的图片。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e此外,在使用 API 之前,需要在设置(齿轮图标)中开启「Dev Mode」,菜单中才会出现「Save(API Format)」选项,从而导出可被脚本调用的工作流 JSON。\u003c/p\u003e\n\u003cp\u003e可以参考这篇分析文章:\u003ca href=\"https://zhuanlan.zhihu.com/p/687537814\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eComfyUI

When responding to user queries, please follow these guidelines: 1. Analyze the user\u0026#39;s question to determine if a diagram would be suitable for explanation or answering. Suitable scenarios for using diagrams include, but are not limited to: process descriptions, hierarchical structures, timelines, relationship maps, etc. 2. If you decide to use a diagram, choose the most appropriate type of Mermaid diagram, such as Flowchart, Sequence Diagram, Class Diagram, State Diagram, Entity Relationship Diagram, User Journey, Gantt, Pie Chart, Quadrant Chart, Requirement Diagram, Gitgraph (Git) Diagram, C4 Diagram, Mindmaps, Timeline, Zenuml, Sankey, XYChart, Block Diagram, etc. 3. Write the diagram code using Mermaid syntax, ensuring the syntax is correct. Place the diagram code between ```mermaid fenced code blocks. 4. Provide textual explanations before and after the diagram, explaining the content and key points of the diagram. 5. If the question is complex, use multiple diagrams to explain different aspects. 6. Ensure the diagram is clear and concise, avoiding over-complication or information overload. 7. Where appropriate, combine textual description and diagrams to comprehensively answer the question. 8. If the user\u0026#39;s question is not suitable for a diagram, answer in a conventional manner without forcing the use of a diagram.

生成的回答涉及到它训练数据之外的知识——比如最新的、专有的或某个特定领域的信息——这时就可能出现事实上的错误（我们称之为\u0026quot;幻觉\u0026quot;）。下面是一个典型案例:\u003c/p\u003e\n\u003cblockquote\u003e\n \u003cp\u003eChatGPT

class=\"header-mark\"\u003e\u003c/a\u003e解决方案\u003c/h3\u003e\u003cp\u003e传统上，要让神经网络适应特定领域或私有信息，人们通常会对模型进行微调。这种方法确实有效，但同时也耗费大量计算资源、成本高昂，且需要丰富的技术知识，因此在快速适应信息变化方面并不灵活。\u003c/p\u003e\n\u003cp\u003e2020 年，Lewis 等人在论文《知识密集型 NLP 任务的检索增强生成》(\u003cem\u003eRetrieval-Augmented Generation for Knowledge-Intensive NLP Tasks\u003c/em\u003e) [1] 中，提出了一种更为灵活的技术——检索增强生成（Retrieval-Augmented Generation,RAG）。该研究将生成模型与检索模块结合起来，能够从易于更新的外部知识源中获取额外信息。\u003c/p\u003e\n\u003cp\u003e用一个简单的比喻来说，RAG 对大语言模型（LLM）的作用，就像开卷考试对学生一样。在开卷考试中，学生可以带着参考资料进场，比如教科书或笔记，用来查找解答问题所需的相关信息。开卷考试的核心在于考察学生的推理能力，而非对具体信息的记忆能力。\u003c/p\u003e\n\u003cp\u003e同样地，在 RAG 中，事实性知识与 LLM 的推理能力相分离，被存储在容易访问和及时更新的外部知识源中。具体而言，知识可以分为两种:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e参数化知识（Parametric knowledge）\u003c/strong\u003e:

with extensive knowledge in many programming languages, frameworks, design patterns, and best practices.\\n\\n====\\n\\nTOOL USE\\n\\nYou have access to a set of tools that are executed upon the user\u0026#39;s approval. You can use one tool per message, and will receive the result of that tool use in the user\u0026#39;s response. You use tools step-by-step to accomplish a given task, with each tool use informed by the result of the previous tool use.\\n\\n# Tool Use Formatting\\n\\nTool use is formatted using XML-style tags. The tool name is enclosed in opening and closing tags, and each parameter is similarly enclosed within its own set of tags. Here\u0026#39;s the structure:\\n\\n\u0026lt;tool_name\u0026gt;\\n\u0026lt;parameter1_name\u0026gt;value1\u0026lt;/parameter1_name\u0026gt;\\n\u0026lt;parameter2_name\u0026gt;value2\u0026lt;/parameter2_name\u0026gt;\\n...\\n\u0026lt;/tool_name\u0026gt;\\n\\nFor example:\\n\\n\u0026lt;read_file\u0026gt;\\n\u0026lt;path\u0026gt;src/main.js\u0026lt;/path\u0026gt;\\n\u0026lt;/read_file\u0026gt;\\n\\nAlways adhere to this format for the tool use to ensure proper parsing and execution.\\n\\n# Tools\\n\\n## execute_command\\nDescription: Request to execute a CLI command on the system. Use this when you need to perform system operations or run specific commands to accomplish any step in the user\u0026#39;s task. You must tailor your command to the user\u0026#39;s system and provide a clear explanation of what the command does. For command chaining, use the appropriate chaining syntax for the user\u0026#39;s shell. Prefer to execute complex CLI commands over creating executable scripts, as they are more flexible and easier to run. Commands will be executed in the current working directory: /Users/erik/MySources/test\\nParameters:\\n- command: (required) The CLI command to execute. This should be valid for the current operating system. Ensure the command is properly formatted and does not contain any harmful instructions.\\n- requires_approval: (required) A boolean indicating whether this command requires explicit user approval before execution in case the user has auto-approve mode enabled. Set to \u0026#39;true\u0026#39; for potentially impactful operations like installing/uninstalling packages, deleting/overwriting files, system configuration changes, network operations, or any commands that could have unintended side effects. Set to \u0026#39;false\u0026#39; for safe operations like reading files/directories, running development servers, building projects, and other non-destructive operations.\\nUsage:\\n\u0026lt;execute_command\u0026gt;\\n\u0026lt;command\u0026gt;Your command here\u0026lt;/command\u0026gt;\\n\u0026lt;requires_approval\u0026gt;true or false\u0026lt;/requires_approval\u0026gt;\\n\u0026lt;/execute_command\u0026gt;\\n\\n## read_file\\nDescription: Request to read the contents of a file at the specified path. Use this when you need to examine the contents of an existing file you do not know the contents of, for example to analyze code, review text files, or extract information from configuration files. Automatically extracts raw text from PDF and DOCX files. May not be suitable for other types of binary files, as it returns the raw content as a string.\\nParameters:\\n- path: (required) The path of the file to read (relative to the current working directory /Users/erik/MySources/test)\\nUsage:\\n\u0026lt;read_file\u0026gt;\\n\u0026lt;path\u0026gt;File path here\u0026lt;/path\u0026gt;\\n\u0026lt;/read_file\u0026gt;\\n\\n## write_to_file\\nDescription: Request to write content to a file at the specified path. If the file exists, it will be overwritten with the provided content. If the file doesn\u0026#39;t exist, it will be created. This tool will automatically create any directories needed to write the file.\\nParameters:\\n- path: (required) The path of the file to write to (relative to the current working directory /Users/erik/MySources/test)\\n- content: (required) The content to write to the file. ALWAYS provide the COMPLETE intended content of the file, without any truncation or omissions. You MUST include ALL parts of the file, even if they haven\u0026#39;t been modified.\\nUsage:\\n\u0026lt;write_to_file\u0026gt;\\n\u0026lt;path\u0026gt;File path here\u0026lt;/path\u0026gt;\\n\u0026lt;content\u0026gt;\\nYour file content here\\n\u0026lt;/content\u0026gt;\\n\u0026lt;/write_to_file\u0026gt;\\n\\n## replace_in_file\\nDescription: Request to replace sections of content in an existing file using SEARCH/REPLACE blocks that define exact changes to specific parts of the file. This tool should be used when you need to make targeted changes to specific parts of a file.\\nParameters:\\n- path: (required) The path of the file to modify (relative to the current working directory /Users/erik/MySources/test)\\n- diff: (required) One or more SEARCH/REPLACE blocks following this exact format:\\n ```\\n \u0026lt;\u0026lt;\u0026lt;\u0026lt;\u0026lt;\u0026lt;\u0026lt; SEARCH\\n [exact content to find]\\n =======\\n [new content to replace with]\\n \u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt; REPLACE\\n ```\\n Critical rules:\\n 1. SEARCH content must match the associated file section to find EXACTLY:\\n * Match character-for-character including whitespace, indentation, line endings\\n * Include all comments, docstrings, etc.\\n 2. SEARCH/REPLACE blocks will ONLY replace the first match occurrence.\\n * Including multiple unique SEARCH/REPLACE blocks if you need to make multiple changes.\\n * Include *just* enough lines in each SEARCH section to uniquely match each set of lines that need to change.\\n * When using multiple SEARCH/REPLACE blocks, list them in the order they appear in the file.\\n 3. Keep SEARCH/REPLACE blocks concise:\\n * Break large SEARCH/REPLACE blocks into a series of smaller blocks that each change a small portion of the file.\\n * Include just the changing lines, and a few surrounding lines if needed for uniqueness.\\n * Do not include long runs of unchanging lines in SEARCH/REPLACE blocks.\\n * Each line must be complete. Never truncate lines mid-way through as this can cause matching failures.\\n 4. Special operations:\\n * To move code: Use two SEARCH/REPLACE blocks (one to delete from original + one to insert at new location)\\n * To delete code: Use empty REPLACE section\\nUsage:\\n\u0026lt;replace_in_file\u0026gt;\\n\u0026lt;path\u0026gt;File path here\u0026lt;/path\u0026gt;\\n\u0026lt;diff\u0026gt;\\nSearch and replace blocks here\\n\u0026lt;/diff\u0026gt;\\n\u0026lt;/replace_in_file\u0026gt;\\n\\n## search_files\\nDescription: Request to perform a regex search across files in a specified directory, providing context-rich results. This tool searches for patterns or specific content across multiple files, displaying each match with encapsulating context.\\nParameters:\\n- path: (required) The path of the directory to search in (relative to the current working directory /Users/erik/MySources/test). This directory will be recursively searched.\\n- regex: (required) The regular expression pattern to search for. Uses Rust regex syntax.\\n- file_pattern: (optional) Glob pattern to filter files (e.g., \u0026#39;*.ts\u0026#39; for TypeScript files). If not provided, it will search all files (*).\\nUsage:\\n\u0026lt;search_files\u0026gt;\\n\u0026lt;path\u0026gt;Directory path here\u0026lt;/path\u0026gt;\\n\u0026lt;regex\u0026gt;Your regex pattern here\u0026lt;/regex\u0026gt;\\n\u0026lt;file_pattern\u0026gt;file pattern here (optional)\u0026lt;/file_pattern\u0026gt;\\n\u0026lt;/search_files\u0026gt;\\n\\n## list_files\\nDescription: Request to list files and directories within the specified directory.

In \u0026lt;thinking\u0026gt; tags, assess what information you already have and what information you need to proceed with the task.\\n2. Choose the most appropriate tool based on the task and the tool descriptions provided. Assess if you need additional information to proceed, and which of the available tools would be most effective for gathering this information. For example using the list_files tool is more effective than running a command like `ls` in the terminal. It\u0026#39;s critical that you think about each available tool and use the one that best fits the current step in the task.\\n3. If multiple actions are needed, use one tool at a time per message to accomplish the task iteratively, with each tool use being informed by the result of the previous tool use. Do not assume the outcome of any tool use. Each step must be informed by the previous step\u0026#39;s result.\\n4. Formulate your tool use using the XML format specified for each tool.\\n5. After each tool use, the user will respond with the result of that tool use. This result will provide you with the necessary information to continue your task or make further decisions. This response may include:\\n - Information about whether the tool succeeded or failed, along with any reasons for failure.\\n - Linter errors that may have arisen due to the changes you made, which you\u0026#39;ll need to address.\\n - New terminal output in reaction to the changes, which you may need to consider or act upon.\\n - Any other relevant feedback or information related to the tool use.\\n6. ALWAYS wait for user confirmation after each tool use before proceeding. Never assume the success of a tool use without explicit confirmation of the result from the user.\\n\\nIt is crucial to proceed step-by-step, waiting for the user\u0026#39;s message after each tool use before moving forward with the task. This approach allows you to:\\n1. Confirm the success of each step before proceeding.\\n2. Address any issues or errors that arise immediately.\\n3. Adapt your approach based on new information or unexpected results.\\n4. Ensure that each action builds correctly on the previous ones.\\n\\nBy waiting for and carefully considering the user\u0026#39;s response after each tool use, you can react accordingly and make informed decisions about how to proceed with the task. This iterative process helps ensure the overall success and accuracy of your work.\\n\\n\\n====\\n\\nMCP SERVERS\\n\\nThe Model Context Protocol (MCP) enables communication between the system and locally running MCP servers that provide additional tools and resources to extend your capabilities.\\n\\n# Connected MCP Servers\\n\\nWhen a server is connected, you can use the server\u0026#39;s tools via the `use_mcp_tool` tool, and access the server\u0026#39;s resources via the `access_mcp_resource` tool.\\n\\n(No MCP servers currently connected)\\n\\n\\n## Creating an MCP Server\\n\\nThe user may ask you something along the lines of \\\u0026#34;add a tool\\\u0026#34; that does some function, in other words to create an MCP server that provides tools and resources that may connect to external APIs for example. You have the ability to create an MCP server and add it to a configuration file that will then expose the tools and resources for you to use with `use_mcp_tool` and `access_mcp_resource`.\\n\\nWhen creating MCP servers, it\u0026#39;s important to understand that they operate in a non-interactive environment. The server cannot initiate OAuth flows, open browser windows, or prompt for user input during runtime. All credentials and authentication tokens must be provided upfront through environment variables in the MCP settings configuration. For example, Spotify\u0026#39;s API uses OAuth to get a refresh token for the user, but the MCP server cannot initiate this flow. While you can walk the user through obtaining an application client ID and secret, you may have to create a separate one-time setup script (like get-refresh-token.js) that captures and logs the final piece of the puzzle: the user\u0026#39;s refresh token (i.e. you might run the script using execute_command which would open a browser for authentication, and then log the refresh token so that you can see it in the command output for you to use in the MCP settings configuration).\\n\\nUnless the user specifies otherwise, new MCP servers should be created in: /Users/erik/Documents/Cline/MCP\\n\\n### Example MCP Server\\n\\nFor example, if the user wanted to give you the ability to retrieve weather information, you could create an MCP server that uses the OpenWeather API to get weather information, add it to the MCP settings configuration file, and then notice that you now have access to new tools and resources in the system prompt that you might use to show the user your new capabilities.\\n\\nThe following example demonstrates how to build an MCP server that provides weather data functionality. While this example shows how to implement resources, resource templates, and tools, in practice you should prefer using tools since they are more flexible and can handle dynamic parameters. The resource and resource template implementations are included here mainly for demonstration purposes of the different MCP capabilities, but a real weather server would likely just expose tools for fetching weather data. (The following steps are for macOS)\\n\\n1. Use the `create-typescript-server` tool to bootstrap a new project in the default MCP servers directory:\\n\\n```bash\\ncd /Users/erik/Documents/Cline/MCP\\nnpx @modelcontextprotocol/create-server weather-server\\ncd weather-server\\n# Install dependencies\\nnpm install axios\\n```\\n\\nThis will create a new project with the following structure:\\n\\n```\\nweather-server/\\n ├── package.json\\n {\\n ...\\n \\\u0026#34;type\\\u0026#34;: \\\u0026#34;module\\\u0026#34;, // added by default, uses ES module syntax (import/export) rather than CommonJS (require/module.exports) (Important to know if you create additional scripts in this server repository like a get-refresh-token.js script)\\n \\\u0026#34;scripts\\\u0026#34;: {\\n \\\u0026#34;build\\\u0026#34;: \\\u0026#34;tsc \u0026amp;\u0026amp; node -e \\\u0026#34;require(\u0026#39;fs\u0026#39;).chmodSync(\u0026#39;build/index.js\u0026#39;, \u0026#39;755\u0026#39;)\\\u0026#34;\\\u0026#34;,\\n ...\\n }\\n ...\\n }\\n ├── tsconfig.json\\n └── src/\\n └── weather-server/\\n └── index.ts # Main server implementation\\n```\\n\\n2.

Build and compile the executable JavaScript file\\n\\n```bash\\nnpm run build\\n```\\n\\n4. Whenever you need an environment variable such as an API key to configure the MCP server, walk the user through the process of getting the key. For example, they may need to create an account and go to a developer dashboard to generate the key. Provide step-by-step instructions and URLs to make it easy for the user to retrieve the necessary information. Then use the ask_followup_question tool to ask the user for the key, in this case the OpenWeather API key.\\n\\n5. Install the MCP Server by adding the MCP server configuration to the settings file located at \u0026#39;/Users/erik/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json\u0026#39;. The settings file may have other MCP servers already configured, so you would read it first and then add your new server to the existing `mcpServers` object.\\n\\nIMPORTANT: Regardless of what else you see in the MCP settings file, you must default any new MCP servers you create to disabled=false and autoApprove=[].\\n\\n```json\\n{\\n \\\u0026#34;mcpServers\\\u0026#34;: {\\n ...,\\n \\\u0026#34;weather\\\u0026#34;: {\\n \\\u0026#34;command\\\u0026#34;: \\\u0026#34;node\\\u0026#34;,\\n \\\u0026#34;args\\\u0026#34;: [\\\u0026#34;/path/to/weather-server/build/index.js\\\u0026#34;],\\n \\\u0026#34;env\\\u0026#34;: {\\n \\\u0026#34;OPENWEATHER_API_KEY\\\u0026#34;: \\\u0026#34;user-provided-api-key\\\u0026#34;\\n }\\n },\\n }\\n}\\n```\\n\\n(Note: the user may also ask you to install the MCP server to the Claude desktop app, in which case you would read then modify `~/Library/Application Support/Claude/claude_desktop_config.json` on macOS for example. It follows the same format of a top level `mcpServers` object.)\\n\\n6. After you have edited the MCP settings configuration file, the system will automatically run all the servers and expose the available tools and resources in the \u0026#39;Connected MCP Servers\u0026#39; section. (Note: If you encounter a \u0026#39;not connected\u0026#39; error when testing a newly installed mcp server, a common cause is an incorrect build path in your MCP settings configuration. Since compiled JavaScript files are commonly output to either \u0026#39;dist/\u0026#39; or \u0026#39;build/\u0026#39; directories, double-check that the build path in your MCP settings matches where your files are actually being compiled. E.g. If you assumed \u0026#39;build\u0026#39; as the folder, check tsconfig.json to see if it\u0026#39;s using \u0026#39;dist\u0026#39; instead.)\\n\\n7. Now that you have access to these new tools and resources, you may suggest ways the user can command you to invoke them - for example, with this new weather tool now available, you can invite the user to ask \\\u0026#34;what\u0026#39;s the weather in San Francisco?\\\u0026#34;\\n\\n## Editing MCP Servers\\n\\nThe user may ask to add tools or resources that may make sense to add to an existing MCP server (listed under \u0026#39;Connected MCP Servers\u0026#39; below: (None running currently), e.g. if it would use the same API. This would be possible if you can locate the MCP server repository on the user\u0026#39;s system by looking at the server arguments for a filepath. You might then use list_files and read_file to explore the files in the repository, and use replace_in_file to make changes to the files.\\n\\nHowever some MCP servers may be running from installed packages rather than a local repository, in which case it may make more sense to create a new MCP server.\\n\\n# MCP Servers Are Not Always Necessary\\n\\nThe user may not always request the use or creation of MCP servers. Instead, they might provide tasks that can be completed with existing tools. While using the MCP SDK to extend your capabilities can be useful, it\u0026#39;s important to understand that this is just one specialized type of task you can accomplish. You should only implement MCP servers when the user explicitly requests it (e.g., \\\u0026#34;add a tool that...\\\u0026#34;).\\n\\nRemember: The MCP documentation and example provided above are to help you understand and work with existing MCP servers or create new ones when requested by the user. You already have access to tools and capabilities that can be used to accomplish a wide range of tasks.\\n\\n\\n====\\n\\nEDITING FILES\\n\\nYou have access to two tools for working with files: **write_to_file** and **replace_in_file**. Understanding their roles and selecting the right one for the job will help ensure efficient and accurate modifications.\\n\\n# write_to_file\\n\\n## Purpose\\n\\n- Create a new file, or overwrite the entire contents of an existing file.\\n\\n## When to Use\\n\\n- Initial file creation, such as when scaffolding a new project. \\n- Overwriting large boilerplate files where you want to replace the entire content at once.\\n- When the complexity or number of changes would make replace_in_file unwieldy or error-prone.\\n- When you need to completely restructure a file\u0026#39;s content or change its fundamental organization.\\n\\n## Important Considerations\\n\\n- Using write_to_file requires providing the file’s complete final content. \\n- If you only need to make small changes to an existing file, consider using replace_in_file instead to avoid unnecessarily rewriting the entire file.\\n- While write_to_file should not be your default choice, don\u0026#39;t hesitate to use it when the situation truly calls for it.\\n\\n# replace_in_file\\n\\n## Purpose\\n\\n- Make targeted edits to specific parts of an existing file without overwriting the entire file.\\n\\n## When to Use\\n\\n- Small, localized changes like updating a few lines, function implementations, changing variable names, modifying a section of text, etc.\\n- Targeted improvements where only specific portions of the file’s content needs to be altered.\\n- Especially useful for long files where much of the file will remain unchanged.\\n\\n## Advantages\\n\\n- More efficient for minor edits, since you don’t need to supply the entire file content. \\n- Reduces the chance of errors that can occur when overwriting large files.\\n\\n# Choosing the Appropriate Tool\\n\\n- **Default to replace_in_file** for most changes. It\u0026#39;s the safer, more precise option that minimizes potential issues.\\n- **Use write_to_file** when:\\n - Creating new files\\n - The changes are so extensive that using replace_in_file would be more complex or risky\\n - You need to completely reorganize or restructure a file\\n - The file is relatively small and the changes affect most of its content\\n - You\u0026#39;re generating boilerplate or template files\\n\\n# Auto-formatting Considerations\\n\\n- After using either write_to_file or replace_in_file, the user\u0026#39;s editor may automatically format the file\\n- This auto-formatting may modify the file contents, for example:\\n - Breaking single lines into multiple lines\\n - Adjusting indentation to match project style (e.g. 2 spaces vs 4 spaces vs tabs)\\n - Converting single quotes to double quotes (or vice versa based on project preferences)\\n - Organizing imports (e.g. sorting, grouping by type)\\n - Adding/removing trailing commas in objects and arrays\\n - Enforcing consistent brace style (e.g. same-line vs new-line)\\n - Standardizing semicolon usage (adding or removing based on style)\\n- The write_to_file and replace_in_file tool responses will include the final state of the file after any auto-formatting\\n- Use this final state as your reference point for any subsequent edits. This is ESPECIALLY important when crafting SEARCH blocks for replace_in_file which require the content to match what\u0026#39;s in the file exactly.\\n\\n# Workflow Tips\\n\\n1. Before editing, assess the scope of your changes and decide which tool to use.\\n2. For targeted edits, apply replace_in_file with carefully crafted SEARCH/REPLACE blocks. If you need multiple changes, you can stack multiple SEARCH/REPLACE blocks within a single replace_in_file call.\\n3. For major overhauls or initial file creation, rely on write_to_file.\\n4. Once the file has been edited with either write_to_file or replace_in_file, the system will provide you with the final state of the modified file. Use this updated content as the reference point for any subsequent SEARCH/REPLACE operations, since it reflects any auto-formatting or user-applied changes.\\n\\nBy thoughtfully selecting between write_to_file and replace_in_file, you can make your file editing process smoother, safer, and more efficient.\\n\\n====\\n \\nACT MODE V.S. PLAN MODE\\n\\nIn each user message, the environment_details will specify the current mode. There are two modes:\\n\\n- ACT MODE: In this mode, you have access to all tools EXCEPT the plan_mode_response tool.\\n - In ACT MODE, you use tools to accomplish the user\u0026#39;s task. Once you\u0026#39;ve completed the user\u0026#39;s task, you use the attempt_completion tool to present the result of the task to the user.\\n- PLAN MODE: In this special mode, you have access to the plan_mode_response tool.\\n - In PLAN MODE, the goal is to gather information and get context to create a detailed plan for accomplishing the task, which the user will review and approve before they switch you to ACT MODE to implement the solution.\\n - In PLAN MODE, when you need to converse with the user or present a plan, you should use the plan_mode_response tool to deliver your response directly, rather than using \u0026lt;thinking\u0026gt; tags to analyze when to respond. Do not talk about using plan_mode_response - just use it directly to share your thoughts and provide helpful answers.\\n\\n## What is PLAN MODE?\\n\\n- While you are usually in ACT MODE, the user may switch to PLAN MODE in order to have a back and forth with you to plan how to best accomplish the task. \\n- When starting in PLAN MODE, depending on the user\u0026#39;s request, you may need to do some information gathering e.g. using read_file or search_files to get more context about the task. You may also ask the user clarifying questions to get a better understanding of the task. You may return mermaid diagrams to visually display your understanding.\\n- Once you\u0026#39;ve gained more context about the user\u0026#39;s request, you should architect a detailed plan for how you will accomplish the task. Returning mermaid diagrams may be helpful here as well.\\n- Then you might ask the user if they are pleased with this plan, or if they would like to make any changes. Think of this as a brainstorming session where you can discuss the task and plan the best way to accomplish it.\\n- If at any point a mermaid diagram would make your plan clearer to help the user quickly see the structure, you are encouraged to include a Mermaid code block in the response. (Note: if you use colors in your mermaid diagrams, be sure to use high contrast colors so the text is readable.)\\n- Finally once it seems like you\u0026#39;ve reached a good plan, ask the user to switch you back to ACT MODE to implement the solution.\\n\\n====\\n \\nCAPABILITIES\\n\\n- You have access to tools that let you execute CLI commands on the user\u0026#39;s computer, list files, view source code definitions, regex search, read and edit files, and ask follow-up questions. These tools help you effectively accomplish a wide range of tasks, such as writing code, making edits or improvements to existing files, understanding the current state of a project, performing system operations, and much more.\\n- When the user initially gives you a task, a recursive list of all filepaths in the current working directory (\u0026#39;/Users/erik/MySources/test\u0026#39;) will be included in environment_details. This provides an overview of the project\u0026#39;s file structure, offering key insights into the project from directory/file names (how developers conceptualize and organize their code) and file extensions (the language used). This can also guide decision-making on which files to explore further. If you need to further explore directories such as outside the current working directory, you can use the list_files tool. If you pass \u0026#39;true\u0026#39; for the recursive parameter, it will list files recursively. Otherwise, it will list files at the top level, which is better suited for generic directories where you don\u0026#39;t necessarily need the nested structure, like the Desktop.\\n- You can use search_files to perform regex searches across files in a specified directory, outputting context-rich results that include surrounding lines. This is particularly useful for understanding code patterns, finding specific implementations, or identifying areas that need refactoring.\\n- You can use the list_code_definition_names tool to get an overview of source code definitions for all files at the top level of a specified directory. This can be particularly useful when you need to understand the broader context and relationships between certain parts of the code. You may need to call this tool multiple times to understand various parts of the codebase related to the task.\\n\\t- For example, when asked to make edits or improvements you might analyze the file structure in the initial environment_details to get an overview of the project, then use list_code_definition_names to get further insight using source code definitions for files located in relevant directories, then read_file to examine the contents of relevant files, analyze the code and suggest improvements or make necessary edits, then use the replace_in_file tool to implement changes. If you refactored code that could affect other parts of the codebase, you could use search_files to ensure you update other files as needed.\\n- You can use the execute_command tool to run commands on the user\u0026#39;s computer whenever you feel it can help accomplish the user\u0026#39;s task. When you need to execute a CLI command, you must provide a clear explanation of what the command does. Prefer to execute complex CLI commands over creating executable scripts, since they are more flexible and easier to run. Interactive and long-running commands are allowed, since the commands are run in the user\u0026#39;s VSCode terminal. The user may keep commands running in the background and you will be kept updated on their status along the way. Each command you execute is run in a new terminal instance.\\n\\n- You have access to MCP servers that may provide additional tools and resources. Each server may provide different capabilities that you can use to accomplish tasks more effectively.\\n\\n\\n====\\n\\nRULES\\n\\n- Your current working directory is: /Users/erik/MySources/test\\n- You cannot `cd` into a different directory to complete a task. You are stuck operating from \u0026#39;/Users/erik/MySources/test\u0026#39;, so be sure to pass in the correct \u0026#39;path\u0026#39; parameter when using tools that require a path.\\n- Do not use the ~ character or $HOME to refer to the home directory.\\n- Before using the execute_command tool, you must first think about the SYSTEM INFORMATION context provided to understand the user\u0026#39;s environment and tailor your commands to ensure they are compatible with their system. You must also consider if the command you need to run should be executed in a specific directory outside of the current working directory \u0026#39;/Users/erik/MySources/test\u0026#39;, and if so prepend with `cd`\u0026#39;ing into that directory \u0026amp;\u0026amp; then executing the command (as one command since you are stuck operating from \u0026#39;/Users/erik/MySources/test\u0026#39;). For example, if you needed to run `npm install` in a project outside of \u0026#39;/Users/erik/MySources/test\u0026#39;, you would need to prepend with a `cd` i.e. pseudocode for this would be `cd (path to project) \u0026amp;\u0026amp; (command, in this case npm install)`.\\n- When using the search_files tool, craft your regex patterns carefully to balance specificity and flexibility. Based on the user\u0026#39;s task you may use it to find code patterns, TODO comments, function definitions, or any text-based information across the project. The results include context, so analyze the surrounding code to better understand the matches. Leverage the search_files tool in combination with other tools for more comprehensive analysis. For example, use it to find specific code patterns, then use read_file to examine the full context of interesting matches before using replace_in_file to make informed changes.\\n- When creating a new project (such as an app, website, or any software project), organize all new files within a dedicated project directory unless the user specifies otherwise. Use appropriate file paths when creating files, as the write_to_file tool will automatically create any necessary directories. Structure the project logically, adhering to best practices for the specific type of project being created. Unless otherwise specified, new projects should be easily run without additional setup, for example most projects can be built in HTML, CSS, and JavaScript - which you can open in a browser.\\n- Be sure to consider the type of project (e.g. Python, JavaScript, web application) when determining the appropriate structure and files to include. Also consider what files may be most relevant to accomplishing the task, for example looking at a project\u0026#39;s manifest file would help you understand the project\u0026#39;s dependencies, which you could incorporate into any code you write.\\n- When making changes to code, always consider the context in which the code is being used. Ensure that your changes are compatible with the existing codebase and that they follow the project\u0026#39;s coding standards and best practices.\\n- When you want to modify a file, use the replace_in_file or write_to_file tool directly with the desired changes. You do not need to display the changes before using the tool.\\n- Do not ask for more information than necessary. Use the tools provided to accomplish the user\u0026#39;s request efficiently and effectively. When you\u0026#39;ve completed your task, you must use the attempt_completion tool to present the result to the user. The user may provide feedback, which you can use to make improvements and try again.\\n- You are only allowed to ask the user questions using the ask_followup_question tool. Use this tool only when you need additional details to complete a task, and be sure to use a clear and concise question that will help you move forward with the task. However if you can use the available tools to avoid having to ask the user questions, you should do so. For example, if the user mentions a file that may be in an outside directory like the Desktop, you should use the list_files tool to list the files in the Desktop and check if the file they are talking about is there, rather than asking the user to provide the file path themselves.\\n- When executing commands, if you don\u0026#39;t see the expected output, assume the terminal executed the command successfully and proceed with the task. The user\u0026#39;s terminal may be unable to stream the output back properly. If you absolutely need to see the actual terminal output, use the ask_followup_question tool to request the user to copy and paste it back to you.\\n- The user may provide a file\u0026#39;s contents directly in their message, in which case you shouldn\u0026#39;t use the read_file tool to get the file contents again since you already have it.\\n- Your goal is to try to accomplish the user\u0026#39;s task, NOT engage in a back and forth conversation.\\n- NEVER end attempt_completion result with a question or request to engage in further conversation! Formulate the end of your result in a way that is final and does not require further input from the user.\\n- You are STRICTLY FORBIDDEN from starting your messages with \\\u0026#34;Great\\\u0026#34;, \\\u0026#34;Certainly\\\u0026#34;, \\\u0026#34;Okay\\\u0026#34;, \\\u0026#34;Sure\\\u0026#34;. You should NOT be conversational in your responses, but rather direct and to the point. For example you should NOT say \\\u0026#34;Great, I\u0026#39;ve updated the CSS\\\u0026#34; but instead something like \\\u0026#34;I\u0026#39;ve updated the CSS\\\u0026#34;. It is important you be clear and technical in your messages.\\n- When presented with images, utilize your vision capabilities to thoroughly examine them and extract meaningful information. Incorporate these insights into your thought process as you accomplish the user\u0026#39;s task.\\n- At the end of each user message, you will automatically receive environment_details. This information is not written by the user themselves, but is auto-generated to provide potentially relevant context about the project structure and environment. While this information can be valuable for understanding the project context, do not treat it as a direct part of the user\u0026#39;s request or response. Use it to inform your actions and decisions, but don\u0026#39;t assume the user is explicitly asking about or referring to this information unless they clearly do so in their message. When using environment_details, explain your actions clearly to ensure the user understands, as they may not be aware of these details.\\n- Before executing commands, check the \\\u0026#34;Actively Running Terminals\\\u0026#34; section in environment_details. If present, consider how these active processes might impact your task. For example, if a local development server is already running, you wouldn\u0026#39;t need to start it again. If no active terminals are listed, proceed with command execution as normal.\\n- When using the replace_in_file tool, you must include complete lines in your SEARCH blocks, not partial lines. The system requires exact line matches and cannot match partial lines. For example, if you want to match a line containing \\\u0026#34;const x = 5;\\\u0026#34;, your SEARCH block must include the entire line, not just \\\u0026#34;x = 5\\\u0026#34; or other fragments.\\n- When using the replace_in_file tool, if you use multiple SEARCH/REPLACE blocks, list them in the order they appear in the file. For example if you need to make changes to both line 10 and line 50, first include the SEARCH/REPLACE block for line 10, followed by the SEARCH/REPLACE block for line 50.\\n- It is critical you wait for the user\u0026#39;s response after each tool use, in order to confirm the success of the tool use. For example, if asked to make a todo app, you would create a file, wait for the user\u0026#39;s response it was created successfully, then create another file if needed, wait for the user\u0026#39;s response it was created successfully, etc.\\n\\n- MCP operations should be used one at a time, similar to other tool usage. Wait for confirmation of success before proceeding with additional operations.\\n\\n\\n====\\n\\nSYSTEM INFORMATION\\n\\nOperating System: macOS\\nDefault Shell: /bin/zsh\\nHome Directory: /Users/erik\\nCurrent Working Directory: /Users/erik/MySources/test\\n\\n====\\n\\nOBJECTIVE\\n\\nYou accomplish a given task iteratively, breaking it down into clear steps and working through them methodically.\\n\\n1. Analyze the user\u0026#39;s task and set clear, achievable goals to accomplish it. Prioritize these goals in a logical order.\\n2. Work through these goals sequentially, utilizing available tools one at a time as necessary. Each goal should correspond to a distinct step in your problem-solving process. You will be informed on the work completed and what\u0026#39;s remaining as you go.\\n3. Remember, you have extensive capabilities with access to a wide range of tools that can be used in powerful and clever ways as necessary to accomplish each goal. Before calling a tool, do some analysis within \u0026lt;thinking\u0026gt;\u0026lt;/thinking\u0026gt; tags. First, analyze the file structure provided in environment_details to gain context and insights for proceeding effectively. Then, think about which of the provided tools is the most relevant tool to accomplish the user\u0026#39;s task. Next, go through each of the required parameters of the relevant tool and determine if the user has directly provided or given enough information to infer a value. When deciding if the parameter can be inferred, carefully consider all the context to see if it supports a specific value. If all of the required parameters are present or can be reasonably inferred, close the thinking tag and proceed with the tool use. BUT, if one of the values for a required parameter is missing, DO NOT invoke the tool (not even with fillers for the missing params) and instead, ask the user to provide the missing parameters using the ask_followup_question tool. DO NOT ask for more information on optional parameters if it is not provided.\\n4. Once you\u0026#39;ve completed the user\u0026#39;s task, you must use the attempt_completion tool to present the result of the task to the user. You may also provide a CLI command to showcase the result of your task; this can be particularly useful for web development tasks, where you can run e.g. `open index.html` to show the website you\u0026#39;ve built.\\n5. The user may provide feedback, which you can use to make improvements and try again. But DO NOT continue in pointless back and forth conversations, i.e. don\u0026#39;t end your responses with questions or offers for further assistance.\u0026#34;\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e \u003cspan

的联网搜索并不是把原始网页直接塞给模型，而是先抓取、再切片、再做向量召回，最后把命中的片段作为上下文送入对话。也就是说,\u0026ldquo;搜索\u0026quot;和\u0026quot;召回\u0026quot;在工程上是两段独立的流水线，可以分别替换实现。\u003c/p\u003e\n\u003ch2 id=\"小结\" class=\"headerLink\"\u003e\n

class=\"cl\"\u003e嗯，我现在要思考一下中国的地方行政层级和美国相对应的是哪些。首先，我知道中国的地方政府分为几个级别：省、市、县、镇。那么在美国，他们也有类似但结构不同的层级。\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan

class=\"cl\"\u003e先从最高的层级说起，中国的“省”应该对应美国的州吧。因为在中国，“省”是一个较大的行政区划，类似于美国的州，都是国家下面的一级政府。不过可能还有直辖市，比如北京和上海这些地方，它们的地位是不是也像一些特别的大城市一样？在美国，州下面有县（county），所以中国的“市”或者“县”可能会对应到美国的县。\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e接下来，市在中国也是一个行政层级，有些城市是地级市，而有些则是县级市。这可能对应到美国的一些较小的地方政府，比如市镇或者郡。但是在美国，最大的地方层级其实是州，然后下面是郡（county），郡下还有更小的单位，如city、town或者其他。\n\u003c/span\u003e\u003c/span\u003e\u003cspan

class=\"cl\"\u003e然后，中国的县对应的是乡或镇吗？在中国，县下面有乡和镇，这些是比较基层的行政单位。在美国，这可能类似于town或者village这样的层级。而有些地方可能会有一个教区或其他类型的政府机构，但通常来说，town是更接近中国乡镇的概念。\n\u003c/span\u003e\u003c/span\u003e\u003cspan

class=\"cl\"\u003e最后，镇在中国是最基层的地方政府之一，负责具体的社区事务和服务。在美国，这可能对应到像township这样的结构，或者是更小的村庄或城市分区。\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan

class=\"cl\"\u003e不过我有点不确定的是直辖市的情况。中国的直辖市比如北京、上海这些，它们在行政地位上高于普通省，直接由中央政府管辖。那么美国是否有类似的概念呢？其实，美国没有直辖市这种类型，但有些大城市所在的郡可能有特别的地位或者功能，比如华盛顿特区虽然是一个联邦区，但它不是一个州，而是单独的联邦直辖区域。\n\u003c/span\u003e\u003c/span\u003e\u003cspan

Mac OS X applications and other programs use the\ndefaults system to record user preferences and other information that must be maintained when the applications aren\u0026rsquo;t running (such as default font\nfor new documents, or the position of an Info panel). Much of this information is accessible through an application\u0026rsquo;s Preferences panel, but some of\nit isn\u0026rsquo;t, such as the position of the Info panel. You can access this information with defaults\u003c/p\u003e\n\u003cp\u003eNote: Since applications do access the defaults system while they\u0026rsquo;re running, you shouldn\u0026rsquo;t modify the defaults of a running application. If you\nchange a default in a domain that belongs to a running application, the application won\u0026rsquo;t see the change and might even overwrite the default.\u003c/p\u003e\n\u003cp\u003eUser defaults belong to domains, which typically correspond to individual applications. Each domain has a dictionary of keys and values representing\nits defaults; for example, \u0026ldquo;Default Font\u0026rdquo; = \u0026ldquo;Helvetica\u0026rdquo;. Keys are always strings, but values can be complex data structures comprising arrays,\ndictionaries, strings, and binary data. These data structures are stored as XML Property Lists.\u003c/p\u003e\n\u003cp\u003eThough all applications, system services, and other programs have their own domains, they also share a domain named NSGlobalDomain. If a default\nisn\u0026rsquo;t specified in the application\u0026rsquo;s domain, but is specified in NSGlobalDomain, then the application uses the value in that

Push),所以选型时不必把它当作 httpx 的卖点。此外，httpx 要求 \u003cstrong\u003ePython 3.8+\u003c/strong\u003e,在老项目里替换 \u003ccode\u003erequests\u003c/code\u003e 时要留意最低解释器版本。\u003c/p\u003e\n\u003ch2 id=\"参考\"

+ PHP环境， boinc 对PHP版本有一定要求，如果默认的PHP版本不满足要求，更换版本可能比较麻烦。\u003c/li\u003e\n\u003cli\u003edocker-compose安装方式：1、很多时候使用已有的Mysql即可，不想在docker-compose中集成。2、 makeproject其实只需要运行一次，但集成在docker-compose每次启动均会运行，担心会导致副作用，例如可能把已有的project删除掉。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e所以最佳的方式是将上面的两种搭建方案相结合，这里给出两种方案。\u003c/p\u003e\n\u003cp\u003e方案1：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e自己搭建MySQL服务器\u003c/li\u003e\n\u003cli\u003e源码编译boinc，使用里面的工具，如make_project python工具等【这一步可以直接使用docker镜像 boinc/server_makeproject:latest-defaultargs 代替】。\u003c/li\u003e\n\u003cli\u003edocker镜像只用 docker-compose中的apache，免去自己搭建apache + PHP 的麻烦。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e方案2：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e源码编译boinc，使用里面的工具，如make_project python工具等【这一步可以直接使用docker镜像 boinc/server_makeproject:latest-defaultargs 代替】。\u003c/li\u003e\n\u003cli\u003edocker镜像只用 docker-compose中的apache、mysql，免去自己搭建apache + PHP 的麻烦。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e方案2相较于方案1，省去了自己搭建MySQL服务器的麻烦，因为 boinc-server 对MySQL版本有要求，所以使用docker镜像更方便。\u003c/p\u003e\n\u003ch2 id=\"基于已有的项目搭建服务器\" class=\"headerLink\"\u003e\n

的项目，并且已在本地跑通。现在要将该项目部署到测试环境、正式环境中去。\u003c/p\u003e\n\u003cp\u003e假设使用上述方案2提供服务。那么需要做的工作流程如下：\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e拉取项目代码到本地\u003c/strong\u003e\u003c/p\u003e\n\u003cdiv

\u003ccode\u003econfig.xml\u003c/code\u003e 中添加 \u003ccode\u003e\u0026lt;enable_assignment_multi\u0026gt;1\u0026lt;/enable_assignment_multi\u0026gt;\u003c/code\u003e;开启绑定则添加

\u003ccode\u003e--target_host\u003c/code\u003e 参数。\u003c/li\u003e\n\u003cli\u003e当需要把任务指定给一组主机执行时，可以使用 \u003ccode\u003e--target_user\u003c/code\u003e 参数（这一组主机用同一个账号登录即可）,也可以用 \u003ccode\u003e--target_team\u003c/code\u003e 限定到某个团队。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e特别说明:\u003c/p\u003e\n\u003cp\u003e当任务被绑定时,\u003ccode\u003eworkunit.transitioner_flags\u003c/code\u003e 字段会被设置为 \u003ccode\u003eTRANSITION_NO_NEW_RESULTS\u003c/code\u003e(源码中定义值为 \u003ccode\u003e2\u003c/code\u003e),用于告诉 transitioner 不要再为该工作单元创建 result 实例，改由调度器在匹配到合适的主机后再创建。\u003c/p\u003e\n\u003cp\u003e因此在提交一个绑定的工作单元时，不会直接在 \u003ccode\u003eresult\u003c/code\u003e 表里创建记录，而是先把记录写入 \u003ccode\u003eassignment\u003c/code\u003e 表;等到有主机被分配到该任务后，再在 \u003ccode\u003eresult\u003c/code\u003e 表里创建对应记录。\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e提交工作单元的最佳实践\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003e可以参考 \u003ccode\u003esample_work_generator\u003c/code\u003e(源码位于 \u003ccode\u003esched/sample_work_generator.cpp\u003c/code\u003e,项目搭建后通常以 \u003ccode\u003ebin/sample_work_generator\u003c/code\u003e 形式被守护进程调用)。该示例程序以\u0026quot;维持一个未发送 result 的缓冲（cushion）\u0026ldquo;的思路持续生成工作单元。主要思路总结如下:\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003e将切片文件提前准备好并编号，统一存储在云端（例如腾讯云 COS、对象存储等）进行管理。\u003c/li\u003e\n\u003cli\u003e在提交工作单元之前，先生成 input 文件，input 文件内容为对应的切片编号（或切片下载地址）,再提交。\u003c/li\u003e\n\u003cli\u003e为避免一次性提交过多工作单元导致难以管理，可以对提交做限速：提交前先查询当前未发送（unsent）的 result 数量，只有当该数量低于设定的阈值（比如最多 10 个）时才继续提交。\u003c/li\u003e\n\u003c/ol\u003e\n\u003cblockquote\u003e\n \u003cp\u003e说明:BOINC 自带的 \u003ccode\u003ebin/wu_check\u003c/code\u003e(源码 \u003ccode\u003esched/wu_check.cpp\u003c/code\u003e)主要用于检查 result 的输入文件是否缺失并可选修复，它本身并不直接返回未发送 result 的数量。统计未发送 result 数量需要直接查询数据库(例如统计 \u003ccode\u003eresult\u003c/code\u003e 表中 \u003ccode\u003eserver_state = 2\u003c/code\u003e 的记录数),或参考 \u003ccode\u003esample_work_generator\u003c/code\u003e 中\u0026quot;维持

时,我们经常会遇到一个问题:镜像构建出来后,只能看到一个最终体积,却不知道每一层(layer)到底加了什么、改了什么、又被覆盖或删除了什么。\u003ccode\u003edocker history\u003c/code\u003e 只能给出粗略的命令和尺寸,无法看到具体的文件变化。\u003c/p\u003e\n\u003cp\u003e\u003ca href=\"https://github.com/wagoodman/dive\" target=\"_blank\" rel=\"noopener noreferrer\"\u003edive\u003c/a\u003e 就是为了解决这个问题。它由 Alex Goodman(wagoodman)开发,使用 Go 编写,以 MIT 协议开源,目前在 GitHub 上有超过 5.4 万个 star。它可以在终端里以交互式 UI 展开镜像,按层浏览文件树,并给出一个衡量「镜像浪费空间」的效率分。\u003c/p\u003e\n\u003ch2 id=\"核心能力\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e6%a0%b8%e5%bf%83%e8%83%bd%e5%8a%9b\" class=\"header-mark\"\u003e\u003c/a\u003e核心能力\u003c/h2\u003e\u003cp\u003edive 的价值集中在四件事上。\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e按层展开镜像\u003c/strong\u003e。选中某一层时,左侧会展示该层叠加所有前序层之后的完整文件树;右侧给出当前层以及「当前层 + 前序层累计」两种视角下的修改、新增、删除情况。\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e变更标识\u003c/strong\u003e。在文件树中,被修改、新增、删除的文件会以不同颜色高亮,可以单独看当前层,也可以看聚合后的结果。这对排查「明明 \u003ccode\u003erm\u003c/code\u003e 了为什么镜像没变小」这类问题非常直观。\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e镜像效率评估(Efficiency)\u003c/strong\u003e。dive 会扫描所有层,统计被后续层覆盖、移动或未完整删除的文件,给出一个 0–100% 的效率分以及浪费的字节数。这个指标是它区别于 \u003ccode\u003edocker history\u003c/code\u003e 的关键。\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e构建即分析\u003c/strong\u003e。\u003ccode\u003edive build\u003c/code\u003e 会调用 Docker 构建镜像,构建完成后立刻进入分析界面,省去「先 build 再 dive」的两步操作。\u003c/p\u003e\n\u003ch2 id=\"安装\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e5%ae%89%e8%a3%85\" class=\"header-mark\"\u003e\u003c/a\u003e安装\u003c/h2\u003e\u003cp\u003edive

自研的 Netpoll(基于 epoll),并保留了切换至 Go 标准网络库的能力，具有高易用性、高性能、高扩展性等特点，目前在字节跳动内部已大规模使用。\n", "author" : { "name" : "小智晖" }, "content_html" : "\u003ch2 id=\"fiber\" class=\"headerLink\"\u003e\n \u003ca

V8\u003c/h2\u003e\u003cp\u003eV8 我想不用过多解释了。JavaScript 能有如今的地位，V8 功不可没。它的性能没得说，开启 JIT 后就是业内最强（不只是 JS 领域）。介绍 V8 的文章已经很多，这里不再赘述，下面重点说说 V8 在移动端的表现。\u003c/p\u003e\n\u003cp\u003eV8 同样是 Google 家的产品，每一台 Android 手机出厂都自带基于 Chromium 的 WebView，V8 也一并被捆绑进去。但 V8 与 Chromium 绑定得太紧，不像 iOS 上的 JavaScriptCore 那样被封装为系统库供所有 App 调用。这导致想在 Android 上用 V8，还得自己封装一层。社区里比较出名的项目是 J2V8，它提供了 V8 的 Java bindings。\u003c/p\u003e\n\u003cp\u003eV8 的性能没得说，Android 上也能开启 JIT，但这些优势是有代价的：开启 JIT 后内存占用偏高，V8 自身的包体积也不小（大约 7 MB 左右）。对一个只是用来画 UI 的 Hybrid 系统来说，这就有些奢侈了。\u003c/p\u003e\n\u003ch2 id=\"3-hermes\" class=\"headerLink\"\u003e\n \u003ca href=\"#3-hermes\" class=\"header-mark\"\u003e\u003c/a\u003e3. Hermes\u003c/h2\u003e\u003cp\u003eHermes 是 Facebook 在 2019 年年中开源的一款 JS 引擎。从它的 release 记录可以看出，这是一款专为 React Native 打造的引擎，可以说从设计之初就是冲着 Hybrid UI 系统去的。\u003c/p\u003e\n\u003cp\u003eHermes 一开始的目标就是要替代 RN Android 端原先使用的 JavaScriptCore（因为 JSC 在 Android 端表现比较拉胯）。我们可以理一下时间线：Facebook 自 2019 年 7 月 12 日宣布 Hermes 开源之后，jsc-android 的维护信息就永远停在了 2019 年 6 月 25 日。这个信号暗示得非常明显——JavaScriptCore 的 Android 版本不再维护，大家都去用我们做的 Hermes 吧。\u003c/p\u003e\n\u003cp\u003e此后 Hermes 也登上了 iOS 平台：React Native 0.64（2021 年 3 月发布）正式支持在 iOS 上开启 Hermes（需手动 opt-in），到 React Native 0.70（2022 年 9 月发布）时，Hermes 已经成为 Android 和 iOS 双端的默认引擎。至于它与 Apple 开发者协议（Apple Agreement 3.3.2）相关的合规讨论，大家可以参考我之前的解读文章，这里就不展开了。\u003c/p\u003e\n\u003cp\u003eHermes 的特点主要有两个：一是不支持 JIT，二是支持直接生成/加载字节码。下面分开讲。\u003c/p\u003e\n\u003cp\u003eHermes 不支持 JIT 的主要原因有两个。其一是加入 JIT 后，JS 引擎启动时的预热时间会变长，一定程度上会拉长首屏 TTI（Time To Interactive，页面首次可交互时间）。现在的移动页面都讲究一个「秒开」，TTI 是个相当重要的测量指标。其二是 JIT 会增加包体积和内存占用——Chrome 内存占用高，V8 要承担相当一部分责任。\u003c/p\u003e\n\u003cp\u003e也正因为不支持 JIT，Hermes 在 CPU 密集计算的场景下并不占优势。所以在 Hybrid 系统里，比较合理的做法是充分发挥 JavaScript「胶水语言」的作用：把 CPU 密集的计算（如矩阵变换、参数加密等）放到 Native 层去做，算好后再回传给 JS 表现到 UI 上，这样可以兼顾性能与开发效率。\u003c/p\u003e\n\u003cp\u003eHermes 最引人瞩目的特性就是支持生成字节码。我在之前的博文《跨端框架的核心技术到底是什么？》里也提到过：Hermes 引入 AOT 后，Babel、Minify、Parse、Compile 这些流程全部都在开发者电脑上完成，运行时直接下发字节码让 Hermes 执行即可。\u003c/p\u003e\n\u003ch2 id=\"4-quickjs\" class=\"headerLink\"\u003e\n \u003ca href=\"#4-quickjs\" class=\"header-mark\"\u003e\u003c/a\u003e4.

不是高级程序员，他是天才。在我看来，他的创造力可以超过 20 个高级程序员。我们可以顺着时间轴理一下他创造过些什么：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e1997 年，他提出了计算圆周率的 Bellard 公式（Bailey–Borwein–Plouffe 公式的变体），将计算效率提升了约

TinyGL，这是他在图形学领域的成就。\u003c/li\u003e\n\u003cli\u003e2005 年，发布了 QEMU，这是他在虚拟化领域的成就。\u003c/li\u003e\n\u003cli\u003e2011 年，他用 JavaScript 写了一个 PC 虚拟机 Jslinux，一个跑在浏览器里的 Linux 操作系统。\u003c/li\u003e\n\u003cli\u003e2019 年，发布了 QuickJS，一个支持 ES2020 规范的 JS 虚拟机。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e当人与人之间的差距拉大到几个数量级后，羡慕嫉妒之类的情绪就会转变为崇拜，Bellard 就是这样一个人。\u003c/p\u003e\n\u003cp\u003e收一收心情，我们来看看 QuickJS 这个项目。QuickJS 继承了 Fabrice Bellard 作品的一贯特色——小巧而强大。\u003c/p\u003e\n\u003cp\u003eQuickJS 体积非常小，只有几个 C 文件，没有乱七八糟的第三方依赖。但它的功能又相当完善，JS 语法支持到 ES2020；在

默认的方式，就是使用宿主机的 /etc/resolv.conf（可能这就是有人说使用宿主机的DNS策略的方式吧），但是，kubelet 是可以灵活来配置使用什么文件来进行DNS策略的，我们完全可以使用 kubelet 的参数：–resolv-conf=/etc/resolv.conf 来决定你的DNS解析文件地址。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003eClusterFirst\n这种方式，表示 POD 内的 DNS 使用集群中配置的 DNS 服务，简单来说，就是使用 Kubernetes 中 kubedns 或 coredns 服务进行域名解析。如果解析不成功，才会使用宿主机的 DNS 配置进行解析。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003eClusterFirstWithHostNet\n在某些场景下，我们的 POD 是用 HOST 模式启动的（HOST模式，是共享宿主机网络的），一旦用 HOST 模式，表示这个 POD 中的所有容器，都要使用宿主机的 /etc/resolv.conf 配置进行DNS查询，但如果你想使用了 HOST 模式，还继续使用 Kubernetes 的DNS服务，那就将 dnsPolicy 设置为 ClusterFirstWithHostNet。\u003c/p\u003e\n\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"三-dns-配置\" class=\"headerLink\"\u003e\n

字段中指定以下属性：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003enameservers：将用作于 Pod 的 DNS 服务器的 IP 地址列表。 最多可以指定 3 个 IP 地址。当 Pod 的 dnsPolicy 设置为 “None” 时， 列表必须至少包含一个 IP 地址，否则此属性是可选的。 所列出的服务器将合并到从指定的 DNS 策略生成的基本名称服务器，并删除重复的地址。\u003c/li\u003e\n\u003cli\u003esearches：用于在 Pod 中查找主机名的 DNS 搜索域的列表。此属性是可选的。 指定此属性时，所提供的列表将合并到根据所选 DNS 策略生成的基本搜索域名中。 重复的域名将被删除。Kubernetes 最多允许 6

\u003ccode\u003ebcs-ingress-controller\u003c/code\u003e 就是这类实现，它从早期的 \u003ccode\u003ebcs-clb-controller\u003c/code\u003e 重构而来，具有以下特点:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e支持 \u003cstrong\u003eHTTP / HTTPS / TCP / UDP\u003c/strong\u003e,可对 CLB 监听器参数做精细化配置。\u003c/li\u003e\n\u003cli\u003e单条 Ingress 可同时驱动\u003cstrong\u003e多个跨可用区的 CLB 实例\u003c/strong\u003e,实现容灾。\u003c/li\u003e\n\u003cli\u003e同时支持 \u003cstrong\u003eNodePort 转发\u003c/strong\u003e与\u003cstrong\u003e直连 Pod\u003c/strong\u003e模式，后者通过 Service 的标签选择直接把流量打到 Pod，可按权重做蓝绿/灰度。\u003c/li\u003e\n\u003cli\u003e控制器拆为两层:\u003ccode\u003eingress-controller\u003c/code\u003e 计算 listener 期望状态并下发增量更新,\u003ccode\u003elistener-controller\u003c/code\u003e 把期望状态同步到云负载均衡实例;每个 CLB 实例对应一个独立的 synchronizer goroutine。\u003c/li\u003e\n\u003cli\u003e引入「接收缓存 + 处理中缓存」双层缓冲，合并短时间内的突发事件，防止 Pod 扩缩容引发的 flapping 把云 API 打爆。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e这种「Ingress 声明 + 控制器翻译为基础设施 API」的模式，正是 Ingress API 在云厂商场景下的典型落地。\u003c/p\u003e\n\u003ch2 id=\"小结\" class=\"headerLink\"\u003e\n \u003ca

的三种方式\u003c/h2\u003e\u003cp\u003eKubernetes 中将 Service 暴露给集群外部访问，最常用的有三种类型：NodePort、LoadBalancer 和 Ingress。（ClusterIP 仅在集群内部可达，ExternalName 则通过 DNS CNAME 映射，二者不在本文讨论的对外暴露范围内。）\u003c/p\u003e\n\u003ch3

NodePort\u003c/h3\u003e\u003cp\u003e将 Service 的 \u003ccode\u003etype\u003c/code\u003e 设置为 \u003ccode\u003eNodePort\u003c/code\u003e。此时每个集群节点都会在节点本机上打开一个端口（默认端口范围是 \u003ccode\u003e30000-32767\u003c/code\u003e），并将在该端口上接收到的流量重定向到后端 Service。\u003c/p\u003e\n\u003cp\u003e也就是说，该服务不仅在集群内部 IP 和端口上可以访问，还可以通过任意节点的 \u003ccode\u003e\u0026lt;NodeIP\u0026gt;:\u0026lt;NodePort\u0026gt;\u003c/code\u003e 从外部访问。\u003c/p\u003e\n\u003ch3 id=\"2-loadbalancer\" class=\"headerLink\"\u003e\n \u003ca href=\"#2-loadbalancer\" class=\"header-mark\"\u003e\u003c/a\u003e2. LoadBalancer\u003c/h3\u003e\u003cp\u003e将 Service 的 \u003ccode\u003etype\u003c/code\u003e 设置为 \u003ccode\u003eLoadBalancer\u003c/code\u003e。它是 NodePort 类型的扩展：Kubernetes 会先自动创建 ClusterIP 和 NodePort，然后调用底层云基础设施（由云控制器管理器提供）分配一个专用的外部负载均衡器。负载均衡器把流量转发到各节点上的 NodePort，客户端通过负载均衡器的公网 IP 访问服务。\u003c/p\u003e\n\u003cp\u003e因此 LoadBalancer 通常只能在公有云（如 AWS、GCP、Azure、阿里云等）或安装了兼容负载均衡器实现的裸金属集群上使用。\u003c/p\u003e\n\u003ch3 id=\"3-ingress\" class=\"headerLink\"\u003e\n \u003ca href=\"#3-ingress\" class=\"header-mark\"\u003e\u003c/a\u003e3. Ingress\u003c/h3\u003e\u003cp\u003e创建一个 Ingress 资源，这与前两种方式机制完全不同。Ingress 通过一个 IP 地址（由 Ingress Controller 提供）公开多个服务，通常面向 HTTP/HTTPS 流量，可以根据域名（host）或路径（path）将请求路由到集群内的不同 Service。\u003c/p\u003e\n\u003cp\u003e可以把 Ingress 理解为集群的网关入口，作用类似于 Spring Cloud 中的 Zuul、Spring Cloud Gateway 或 Nginx 反向代理。需要注意，单独创建 Ingress 资源并不会生效，必须先安装一个 Ingress Controller（如 NGINX Ingress Controller、Traefik 等）来实际处理和转发流量。\u003c/p\u003e\n\u003cblockquote\u003e\n \u003cp\u003e提示：Kubernetes 官方目前已推荐使用 \u003ca href=\"https://kubernetes.io/docs/concepts/services-networking/gateway/\"

连接起来。它复用了 kubeconfig 中的认证信息，因此可以通过 HTTP 直接访问 API Server 提供的 REST 接口和资源，而无需把 API Server 直接暴露给外部网络。\u003c/p\u003e\n\u003cp\u003e执行 \u003ccode\u003ekubectl proxy\u003c/code\u003e 后，会在本地启动一个 HTTP 代理，默认监听

对象。理解了 API，就抓住了 Kubernetes 的\u0026quot;牛鼻子\u0026quot;。Kubernetes 的 API 设计遵循以下几条原则:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e所有 API 应该是声明式的\u003c/strong\u003e。声明式操作相对于命令式操作，在重复执行时效果是稳定的，这对于容易出现数据丢失或重复执行的分布式环境来说至关重要。同时，声明式操作更易于用户使用，可以让系统向用户隐藏实现细节，也就保留了系统未来持续优化的空间。此外，声明式 API 隐含了所有 API 对象都是\u0026quot;名词\u0026quot;性质的——例如 Service、Volume，这些名词描述了用户期望得到的目标分布式对象。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eAPI 对象是彼此互补而且可组合的\u003c/strong\u003e。这实际上是鼓励 API 对象尽量满足面向对象设计中的\u0026quot;高内聚、松耦合\u0026quot;,对业务相关的概念做合适的分解，以提高对象的可重用性。Kubernetes 这种分布式系统管理平台本身也是一种业务系统，只不过它的业务就是调度和管理容器服务。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e高层 API 以操作意图为基础设计\u003c/strong\u003e。如何设计好 API，与如何用面向对象方法设计应用系统相通——高层设计一定是从业务出发，而不是过早地从技术实现出发。因此 Kubernetes 的高层 API 一定以其业务为基础，即以\u0026quot;系统调度管理容器的操作意图\u0026quot;为基础进行设计。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e低层 API 根据高层 API 的控制需要设计\u003c/strong\u003e。设计低层 API 的目的是被高层 API 使用，为减少冗余、提高重用性，低层 API 也要以需求为基础，尽量抵抗受技术实现影响的诱惑。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e尽量避免简单封装，不要有外部 API 无法显式感知的内部隐藏机制\u003c/strong\u003e。简单封装并未提供新功能，反而增加了对所封装 API 的依赖。内部隐藏机制也非常不利于系统维护。例如 StatefulSet 和 ReplicaSet 本质上是两种不同的 Pod 集合，Kubernetes 就用不同的 API 对象来定义它们，而不是共用同一个 ReplicaSet、再通过内部算法区分有状态与无状态。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eAPI 操作复杂度与对象数量成正比\u003c/strong\u003e。这条主要从系统性能角度考虑：要保证系统在规模扩大时性能不会迅速退化到不可用，最低限度是 API 的操作复杂度不能超过 O(N)(N 为对象数量),否则系统就不具备水平伸缩性。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eAPI 对象状态不能依赖于网络连接状态\u003c/strong\u003e。在分布式环境下，网络连接断开是常态，因此要保证 API 对象状态能应对网络的不稳定，其状态就不能依赖于网络连接状态。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e尽量避免让操作机制依赖于全局状态\u003c/strong\u003e。因为在分布式系统中，保证全局状态的同步是非常困难的。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"控制机制设计原则\"

Mesh、GitOps 等正交，可灵活组合。对绝大多数新场景而言，Federation 已是历史，Karmada 及周边网络/治理项目才是当下值得投入的方向。\u003c/p\u003e\n\u003ch2 id=\"参考\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e5%8f%82%e8%80%83\"

路由的方式完成互联的。Calico 节点组网可以直接利用数据中心的网络结构（无论是 L2 或者 L3），不需要额外的 NAT、隧道或 Overlay Network。\u003c/p\u003e\n\u003cp\u003e此外，Calico 基于 iptables 还提供了丰富而灵活的网络 Policy，通过各个节点上的 ACLs 来提供 Workload 的多租户隔离、安全组以及其他可达性限制等功能。\u003c/p\u003e\n\u003cp\u003eCalico 主要由 Felix、etcd、BGP Client 以及 BGP Route Reflector 组成：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eFelix\u003c/strong\u003e：Calico Agent，跑在每台需要运行 Workload 的节点上，主要负责配置路由及 ACLs 等信息，确保 Endpoint 的连通状态。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eetcd\u003c/strong\u003e：分布式键值存储，主要负责维护网络元数据一致性，确保 Calico 网络状态的准确性。在 Kubernetes 环境下也可以直接复用 K8s API 作为数据存储（即 \u0026ldquo;Kubernetes API data store\u0026rdquo; 模式），从而不再依赖独立 etcd。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eBGP Client（BIRD）\u003c/strong\u003e：主要负责把 Felix 写入 Kernel 的路由信息分发到当前 Calico 网络，确保 Workload 间通信的有效性。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eBGP Route Reflector（BIRD）\u003c/strong\u003e：大规模部署时使用，摒弃所有节点全互联（full-mesh）的模式，通过一个或多个 BGP Route Reflector 来完成集中式的路由分发。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003ecalico-ipam\u003c/strong\u003e：主要用作 Kubernetes 的 CNI IPAM 插件，负责给 Pod 分配 IP。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"calico-模式\" class=\"headerLink\"\u003e\n \u003ca href=\"#calico-%e6%a8%a1%e5%bc%8f\" class=\"header-mark\"\u003e\u003c/a\u003eCalico 模式\u003c/h2\u003e\u003ch3 id=\"ipip-模式\" class=\"headerLink\"\u003e\n \u003ca href=\"#ipip-%e6%a8%a1%e5%bc%8f\" class=\"header-mark\"\u003e\u003c/a\u003eIPIP 模式\u003c/h3\u003e\u003cp\u003eIPIP（IP-in-IP）是 Calico 历史上最经典的默认网络架构之一（注意：较新的 Calico 版本和托管 Kubernetes 服务已逐步把默认封装切换为 VXLAN，安装时以 manifest/operator 的实际配置为准），它其实也是一种 Overlay 的网络架构，但相比更常用的 VXLAN 模式更加轻量化。IP-in-IP 就是把一个 IP 数据包又套在一个 IP 包里，即把 IP 层封装到 IP 层的一个 tunnel，它的作用基本上相当于一个基于 IP 层的网桥。一般来说，普通的网桥是基于 MAC 层的，根本不需要 IP；而这个 IPIP 则是通过两端的路由建立一个 tunnel，把两个本来不通的网络通过点对点连接起来。\u003c/p\u003e\n\u003cp\u003eCalico 控制平面的设计原本要求物理网络是 L2 Fabric，这样 vRouter 间都是直接可达的，路由不需要把物理设备当做下一跳。为了支持 L3 Fabric，Calico 推出了 IP-in-IP 的选项。\u003c/p\u003e\n\u003ch3 id=\"bgp-模式\" class=\"headerLink\"\u003e\n \u003ca href=\"#bgp-%e6%a8%a1%e5%bc%8f\" class=\"header-mark\"\u003e\u003c/a\u003eBGP 模式\u003c/h3\u003e\u003cp\u003eBGP 模式是 Calico 常用的模式，也是它的王牌模式。需要说明的是，虽然 Calico 有 BGP 模式和 IPIP 模式之分，但并不意味着 IPIP 模式就不用建立 BGP 连接——IPIP 模式同样需要建立 BGP 连接（可以通过抓取 179 端口的报文验证），只不过建立 BGP 链接的目标比较清晰，就是对端 \u003ccode\u003etunl0\u003c/code\u003e 对应的网卡。BGP 模式相对于 IPIP 模式的优点并不是简单的\u0026quot;可以跨节点通信\u0026quot;——IPIP 模式同样可以跨节点通信，只要两个节点能互相连通即可。BGP 的优点在于可以指定 BGP 的对端 Peer（一般是交换机），那么只要能接入这台交换机的 host 或 PC，都能通过路由的方式连通 Calico 其他节点上的容器。也就是说，BGP 的可扩展网络拓扑更灵活。\u003c/p\u003e\n\u003cp\u003eBGP 模式下数据包的路径单纯依靠路由进行转发，网络拓扑更自由；IP-in-IP 模式则多了一个封包的过程，因此也是一种 Overlay 的方式，封好的包再按照路由进行转发，到达目的节点后还有一个解包的过程，所以比 BGP 模式稍微低效一些。但由于封包比 VXLAN 添加的字段更少，因此比 VXLAN 更高效一些。总体而言，IP-in-IP 模式部署起来相对简单，两者各有利弊。\u003c/p\u003e\n\u003ch2 id=\"calico-的不足\" class=\"headerLink\"\u003e\n \u003ca href=\"#calico-%e7%9a%84%e4%b8%8d%e8%b6%b3\"

XDP。\u003c/p\u003e\n\u003ch3 id=\"ebpfextended-bpf\" class=\"headerLink\"\u003e\n \u003ca href=\"#ebpfextended-bpf\" class=\"header-mark\"\u003e\u003c/a\u003eeBPF（extended BPF）\u003c/h3\u003e\u003cp\u003eeBPF（extended Berkeley Packet Filter）起源于经典的 BPF。原始 BPF（被追溯命名为 cBPF，classic BPF）只有两个 32 位寄存器，提供内核数据包过滤机制：用户态通过 \u003ccode\u003eSO_ATTACH_FILTER\u003c/code\u003e 这类 socket 选项把过滤器挂到 socket 上，只有满足条件的数据包才上送到用户空间。\u003c/p\u003e\n\u003cp\u003eeBPF 是对 cBPF 的扩展与重写，引入了十个 64 位寄存器并大幅丰富了指令集。它在内核中提供一个安全沙箱化的虚拟机，用户态把过滤/处理逻辑以字节码的形式通过 \u003ccode\u003ebpf()\u003c/code\u003e 系统调用传入内核，内核经过验证器（verifier）校验安全后 JIT 编译为本机指令执行。自 Linux 3.18 起，内核内置了 eBPF 虚拟机，cBPF 程序在加载时也会被透明地转换为 eBPF 表示。\u003c/p\u003e\n\u003cp\u003e需要注意的是，eBPF 的能力早已不局限于包过滤：通过 attach 到 tracepoint、kprobe、cgroup、socket、TC（Traffic Control）、XDP 等挂载点，它可以用于网络、安全、追踪、观测等多种场景。Cilium 正是把 eBPF 程序挂到 TC、XDP、socket、cgroup 等多个网络路径关键点上，组合出完整的容器网络数据平面。\u003c/p\u003e\n\u003cblockquote\u003e\n \u003cp\u003e原文提到「Linux 3.15 开始引入 eBPF」。准确的说法是 eBPF 的早期合入工作散落在多个内核版本，而 eBPF 虚拟机和 \u003ccode\u003ebpf()\u003c/code\u003e 系统调用通常以 Linux 3.18 为正式引入版本。\u003c/p\u003e\n\n\u003c/blockquote\u003e\u003ch3

内核网络栈中的一个 eBPF 挂载点，位于网卡驱动收包（RX）路径上最早的位置。挂载在 XDP 的 eBPF 程序在数据包刚到达网卡、尚未进入内核协议栈（\u003ccode\u003esk_buff\u003c/code\u003e 分配）之前就会被执行，因此能获得最佳的数据包处理性能，常用于 DDoS 防护、L3/4 负载均衡、早期丢弃等场景。\u003c/p\u003e\n\u003cp\u003eXDP 通常有三种运行模式：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eNative（驱动）模式\u003c/strong\u003e：eBPF

Network Interface），主要用来解决容器跨主机网络通信问题。\u003c/p\u003e\n\u003cp\u003eFlannel 的设计目的就是为集群中的所有节点重新规划 IP 地址的使用规则，从而使得不同节点上的容器能够获得\u0026quot;同属一个内网\u0026quot;且\u0026quot;不重复的\u0026quot;IP 地址，并让属于不同节点上的容器能够直接通过内网 IP 通信。\u003c/p\u003e\n\u003cp\u003eFlannel 实质上是一种\u0026quot;覆盖网络（overlay network）\u0026quot;，也就是将 TCP 数据包装在另一种网络包里面进行路由转发和通信。目前已经支持 udp、vxlan、host-gw、WireGuard、IPIP、IPSec 等数据转发方式，默认的节点间数据通信方式是 \u003cstrong\u003eVXLAN\u003c/strong\u003e。\u003c/p\u003e\n\u003cp\u003e控制平面上，host 本地的 flanneld 负责从远端的 etcd 集群同步本地及其它 host 上的 subnet 信息，并为 Pod 分配 IP 地址。数据平面，flannel 通过 Backend（比如 VXLAN 封装）来实现 L3 Overlay，既可以选择一般的 TUN 设备又可以选择 VxLAN 设备。\u003c/p\u003e\n\u003ch2 id=\"flannel-特点\" class=\"headerLink\"\u003e\n \u003ca href=\"#flannel-%e7%89%b9%e7%82%b9\" class=\"header-mark\"\u003e\u003c/a\u003eFlannel 特点\u003c/h2\u003e\u003cul\u003e\n\u003cli\u003eFlannel 通过给每台宿主机分配一个子网的方式为容器提供虚拟网络，该虚拟网络可基于不同的 Backend 实现，并借助 etcd 维护网络的分配情况。\u003c/li\u003e\n\u003cli\u003e集群中的不同 Node 主机创建的 Docker 容器都具有全集群唯一的虚拟 IP 地址。\u003c/li\u003e\n\u003cli\u003e建立一个覆盖网络（overlay network），通过这个覆盖网络，将数据包原封不动地传递到目标容器。\u003c/li\u003e\n\u003cli\u003e覆盖网络是建立在另一个网络之上并由其基础设施支持的虚拟网络。覆盖网络通过将一个分组封装在另一个分组内来将网络服务与底层基础设施分离。在将封装的数据包转发到端点后，将其解封装。\u003c/li\u003e\n\u003cli\u003e创建一个新的虚拟网卡 flannel.1（VXLAN 模式）接收 docker 网桥的数据，通过维护路由表，对接收到的数据进行封包和转发。\u003c/li\u003e\n\u003cli\u003eetcd 保证了所有 Node 上 flanneld 所看到的配置是一致的。同时每个 Node 上的 flanneld 监听 etcd 上的数据变化，实时感知集群中 Node 的变化。\u003c/li\u003e\n\u003cli\u003eFlannel 利用各种 backend mechanism（例如 VXLAN、host-gw 等）跨主机转发容器间的网络流量，完成容器间的跨主机通信。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"flannel-backend\"

backend\u003c/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eVXLAN（默认）\u003c/strong\u003e：利用内核的 VXLAN 模块实现一个三层的覆盖网络，通过 flannel.1 这个 VTEP（VXLAN Tunnel Endpoints）设备来进行封拆包，然后进行路由转发实现通信。VXLAN 在内核态实现，效率高，是 Flannel 推荐的默认 backend。Linux 上 Flannel 的 VXLAN 默认 UDP 端口为 \u003cstrong\u003e8472\u003c/strong\u003e（注意：IANA 标准 VXLAN 端口为 4789，Flannel 沿用了早期 Linux 内核的历史端口 8472）。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eUDP\u003c/strong\u003e：基于 Linux TUN/TAP，主要是利用 tun 设备来模拟一个虚拟网络进行通信，使用 UDP 封装 IP 包来创建 overlay 网络。由于 UDP 封装在用户态实现，数据包会从内核态多次拷贝，效率较低，官方建议仅用于调试或非常老旧的、不支持 VXLAN 的内核。默认端口为 8285。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003ehost-gw\u003c/strong\u003e：直接修改二层网络的路由信息，实现数据包的转发，从而省去中间封装层，通信效率更高，但要求各个节点之间是二层连通的。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eWireGuard\u003c/strong\u003e：使用内核态 WireGuard 进行封装和加密，适合需要加密通信的场景。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eIPIP / IPSec\u003c/strong\u003e：通过内核 IPIP 或 IPSec 封装，IPSec 可借助 Strongswan 提供加密传输。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"与-calico-对比\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e4%b8%8e-calico-%e5%af%b9%e6%af%94\" class=\"header-mark\"\u003e\u003c/a\u003e与

英文释义：印花棉布\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e为什么要用布来为该插件起名呢？猜测是因为布是由一根根丝线织成的，密密麻麻犹如网状。这跟网络通信由一条条看不见的虚拟链路组成在结构上很相似，所以用代表布的单词来命名。\u003c/p\u003e\n\u003cp\u003e简言之：Flannel 相对简单，只关注 L3 覆盖网络的连通性，配置少、依赖少；Calico 则基于 BGP 实现更丰富的路由能力，并原生支持 NetworkPolicy 做网络隔离，适合对安全策略有更高要求的场景。\u003c/p\u003e\n\u003ch2 id=\"参考\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e5%8f%82%e8%80%83\"

代理——是过去几年最主流的数据平面实现。它功能完备、对应用透明，但在性能与资源开销上代价不菲。\u003c/p\u003e\n\u003cp\u003e传统 Sidecar

的固有延迟，并随着连接数上升而进一步增大。对于延迟敏感型应用，这种常数级开销难以接受。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e资源消耗\u003c/strong\u003e：每个 Pod 都要常驻一个 Sidecar 进程，在大规模集群（数千 Pod）中累积的 CPU 与内存开销相当可观。有估算显示，一个 500 Pod 的集群，仅 Sidecar 自身就可能消耗 25~50GB 内存，显著降低部署密度、抬升运营成本。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e为了突破 Sidecar 模型的瓶颈，社区出现了两条无 Sidecar（sidecarless）演进路线：一条是 Istio Ambient Mesh，用节点级的 ztunnel（L4）与 waypoint（L7）替代 Sidecar；另一条则是 \u003ca href=\"https://github.com/kmesh-net/kmesh\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eKmesh\u003c/a\u003e，它选择把流量治理直接下沉到操作系统内核，利用 eBPF（Extended Berkeley Packet

map）。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003esocket redirection（sk_msg）\u003c/strong\u003e：在数据发送阶段按 key 查找 sockmap，若命中则将数据\u003cstrong\u003e直接转发到目标 socket\u003c/strong\u003e，完全绕过内核协议栈的后续流程。\u003c/li\u003e\n\u003c/ol\u003e\n\u003cp\u003e为了处理 NAT 场景下正向/反向连接的映射关系，Kmesh 还借助 \u003ccode\u003ebpf_get_sockopt\u003c/code\u003e 主动获取被 iptables 改写后的地址，维护一张辅助 map，保证双向流量都能被正确重定向。这就是 Kmesh \u0026ldquo;forged connection（伪造连接）\u0026ldquo;机制的底层实现——在内核里完成治理，无需任何用户态代理介入。\u003c/p\u003e\n\u003ch2 id=\"两种工作模式\" class=\"headerLink\"\u003e\n \u003ca

前面的网络负载均衡器。传入流量 (1) 指向您的服务的负载均衡器。一旦负载均衡器收到数据包 (2)，它就会随机选择一个 VM。在这种情况下，我们病态地选择了没有运行 Pod 的 VM：VM 2 (3)。在这里，运行在 VM 上的 iptables 规则将使用 kube-proxy 安装到集群中的内部负载平衡规则将数据包定向到正确的 Pod。iptables 执行正确的 NAT 并将数据包转发到正确的 Pod (4)。\u003c/p\u003e\n\u003ch5 id=\"七层\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e4%b8%83%e5%b1%82\"

之上。\u003c/li\u003e\n\u003cli\u003e启用 Ingress 的第一步是使用 Kubernetes 中的 NodePort 服务类型在您的服务上打开一个端口。如果将 Service 的 type 字段设置为 NodePort，Kubernetes master 将从您指定的范围内分配一个端口，并且每个 Node 都会将该端口（每个 Node 上的相同端口号）代理到您的 Service 中。也就是说，任何指向节点端口的流量都将使用 iptables 规则转发到服务。这个 Service 到 Pod 的路由遵循我们在将流量从 Service 路由到 Pod 时已经讨论过的相同的内部集群负载平衡模式。\u003c/li\u003e\n\u003cli\u003e要向 Internet 公开节点的端口，您需要使用 Ingress 对象。Ingress 是一个更高级别的 HTTP 负载均衡器，它将 HTTP 请求映射到 Kubernetes 服务。Ingress 方法将根据 Kubernetes 云提供商控制器的实现方式而有所不同。HTTP 负载均衡器，如第 4 层网络负载均衡器，仅了解节点 IP（而不是 Pod IP），因此流量路由同样利用由 kube-proxy 安装在每个节点上的 iptables 规则提供的内部负载均衡。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e在 AWS 环境中，ALB 入口控制器使用 Amazon 的第 7 层应用程序负载均衡器提供 Kubernetes 入口。下图详细介绍了此控制器创建的 AWS 组件。它还演示了 Ingress 流量从 ALB 到 Kubernetes 集群的路由。\u003c/p\u003e\n\u003cp\u003e\u003cimg class=\"tw:inline\" loading=\"lazy\" src='https://wmxiaozhi.github.io/picx-images-hosting/picx-imgs/k8s-net/ingress-controller-design.png'

Ingress 和 Node 之间的初始连接是通过 Node 上为每个服务公开的端口。\u003c/li\u003e\n\u003cli\u003e部署服务后，您正在使用的云提供商将为您创建一个新的 Ingress 负载均衡器 (1)。由于负载均衡器不支持容器，因此一旦流量到达负载均衡器，它就会通过为您的服务提供的广告端口分布在组成集群 (2) 的整个 VM 中。\u003c/li\u003e\n\u003cli\u003e每个 VM 上的 iptables 规则会将来自负载均衡器的传入流量引导到正确的 Pod (3) — 正如我们之前所见。Pod 到客户端的响应将返回 Pod 的 IP，但客户端需要有负载均衡器的 IP 地址。正如我们之前看到的，iptables 和 conntrack 用于在返回路径上正确重写 IP。\u003c/li\u003e\n\u003cli\u003e第 7 层负载均衡器的一个好处是它们可以识别 HTTP，因此它们知道 URL 和路径。这使您可以按 URL 路径对服务流量进行分段。它们通常还在 HTTP 请求的 X-Forwarded-For 标头中提供原始客户端的 IP 地址。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e\u003cimg class=\"tw:inline\" loading=\"lazy\" src='https://wmxiaozhi.github.io/picx-images-hosting/picx-imgs/k8s-net/ingress-to-service.gif'

Service 中。也就是说，任何指向节点端口的流量都将使用 iptables 规则转发到服务。这个 Service 到 Pod 的路由遵循我们在将流量从 Service 路由到 Pod 时已经讨论过的相同的内部集群负载平衡模式。\u003c/li\u003e\n\u003cli\u003e要向 Internet 公开节点的端口，您需要使用 Ingress 对象。Ingress 是一个更高级别的 HTTP 负载均衡器，它将 HTTP 请求映射到 Kubernetes 服务。Ingress 方法将根据 Kubernetes 云提供商控制器的实现方式而有所不同。HTTP 负载均衡器，如第 4 层网络负载均衡器，仅了解节点 IP（而不是 Pod IP），因此流量路由同样利用由 kube-proxy 安装在每个节点上的 iptables

Linux/Unix 系统的一个环境变量，它能够影响程序运行时的链接行为，允许在程序启动前指定优先加载的动态链接库。借助这个环境变量，可以在主程序与其依赖的动态链接库之间插入额外的动态库，甚至覆盖系统标准函数库中的实现。\u003c/p\u003e\n\u003cp\u003e具体来说，Linux 操作系统在加载动态链接库时，动态链接器（\u003ccode\u003eld-linux.so\u003c/code\u003e）会先读取 \u003ccode\u003eLD_PRELOAD\u003c/code\u003e 环境变量和默认配置文件 \u003ccode\u003e/etc/ld.so.preload\u003c/code\u003e，并将其中列出的动态库文件进行预加载。即使目标程序本身并不依赖这些动态库，它们也会被强制加载，因为预加载的优先级高于通过 \u003ccode\u003eLD_LIBRARY_PATH\u003c/code\u003e 指定路径所查找到的库，因此能够先于用户程序调用的动态库载入到进程地址空间。\u003c/p\u003e\n\u003cp\u003e简单来说，LD_PRELOAD 拥有最高的加载优先级，我们可以利用它来完成一些有趣（也略带\u0026quot;黑科技\u0026quot;）的操作。\u003c/p\u003e\n\u003cp\u003e一般情况下，\u003ccode\u003eld-linux.so\u003c/code\u003e 加载动态链接库的顺序大致如下（\u003ccode\u003eLD_PRELOAD\u003c/code\u003e 是预加载机制，严格意义上并不属于\u0026quot;查找顺序\u0026quot;，但它的效果优先于查找过程）：\u003c/p\u003e\n\u003cdiv class=\"code-block highlight is-open show-line-numbers tw:group tw:my-2\"\u003e\n \u003cdiv class=\"\n \n tw:flex \n

外部 IP 头 20 字节 + 外部 MAC 头 14 字节），这样一来，整个报文长度达到了 1550 字节。而现有的 VTEP 设备，一般在解封装 VXLAN 报文时，要求 VXLAN 报文不能被分片，否则无法正确解封装。这就要求 VTEP 之间的所有网络设备的 MTU 最小为 1550 字节。如果中间设备的 MTU 值不方便进行更改，那么设置虚拟机的 MTU 值为 1450，也可以暂时解决这个问题。\u003c/li\u003e\n\u003cli\u003e默认端口的历史：Linux 内核 3.7 版本首次实现 VXLAN 时，IANA 尚未规定标准端口，早期实现沿用了厂商事实上的 8472 端口；IANA 后来正式分配的标准端口是 \u003cstrong\u003e4789\u003c/strong\u003e，Linux 内核 3.15 起将默认值改为 4789。\u003ccode\u003eip link add type vxlan\u003c/code\u003e 可通过 \u003ccode\u003edstport\u003c/code\u003e 参数显式指定端口，以便与硬件 VTEP 互通。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"参考\"

\u003ccode\u003estatic\u003c/code\u003e 全局符号默认就会进入 \u003ccode\u003e.dynsym\u003c/code\u003e 成为导出符号;但主模块并非如此——\u003cstrong\u003e默认情况下主模块根本不把自己的符号导出到 \u003ccode\u003e.dynsym\u003c/code\u003e\u003c/strong\u003e。这也是为什么很多人第一次用 \u003ccode\u003edlsym\u003c/code\u003e 去查自己 \u003ccode\u003emain.c\u003c/code\u003e 里写的函数时，明明函数没被

\u003ccode\u003eA.so\u003c/code\u003e)实际引用了一个同名符号时，链接器才把这个符号加进主模块的 \u003ccode\u003e.dynsym\u003c/code\u003e。换句话说，主模块默认只导出「被别的东西需要」的符号。\u003c/p\u003e\n\u003cp\u003e要让主模块里的所有全局非隐藏符号都对

指令创建若干 \u003cstrong\u003eworker 进程\u003c/strong\u003e。Nginx 收到 \u003ccode\u003e.php\u003c/code\u003e 请求后，通过 FastCGI 协议把请求转给 PHP-FPM 监听的地址（TCP 或 Unix domain socket）,master 把连接分派给某个空闲 worker,worker 执行完 PHP 脚本后将响应回传给 Nginx，再由 Nginx 返回给客户端。\u003c/p\u003e\n\u003cp\u003e整个链路的关键在于:\u003ccode\u003eSCRIPT_FILENAME\u003c/code\u003e 这个 FastCGI 参数必须正确指向磁盘上真实存在的 PHP 文件，否则 PHP-FPM 会直接返回 \u003ccode\u003eFile not

内存池具有如下特点：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e原理\u003c/strong\u003e：内存池是在真正使用内存之前，预先申请分配一定数量的、大小相等（一般情况下）的内存块留作备用。当有新的内存需求时，就从内存池中分出一部分内存块；若内存块不够用时，再继续申请新的内存。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e好处\u003c/strong\u003e：减少向系统申请和释放内存的时间开销，缓解内存频繁分配产生的碎片问题，提升程序性能。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e按生命周期管理\u003c/strong\u003e：Nginx 会为不同的对象分别创建内存池进行内存管理，例如一个 TCP 连接、一个 HTTP 请求等。在对应的生命周期结束时，会摧毁整个内存池，把分配的内存一次性归还给操作系统。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e小块与大块内存的区分\u003c/strong\u003e：在分配内存时，Nginx 区分小块内存与大块内存。对于小块内存，Nginx 会尝试在当前的内存池结点中分配；对于大块内存，则调用系统函数 \u003ccode\u003emalloc\u003c/code\u003e 向操作系统申请。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e小块内存不单独释放\u003c/strong\u003e：在释放内存时，Nginx 没有专门提供针对小块内存的释放函数，小块内存会在 \u003ccode\u003engx_destroy_pool\u003c/code\u003e 和 \u003ccode\u003engx_reset_pool\u003c/code\u003e 时一并释放。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e大块内存可单独释放\u003c/strong\u003e：针对大块内存，Nginx 提供了单独的释放函数 \u003ccode\u003engx_pfree\u003c/code\u003e（仅对挂在 \u003ccode\u003elarge\u003c/code\u003e 链表上的大块内存生效，对小块内存返回 \u003ccode\u003eNGX_DECLINED\u003c/code\u003e）。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e大块与小块的分界线是一页内存\u003c/strong\u003e：\u003ccode\u003ep-\u0026gt;max = (size \u0026lt; NGX_MAX_ALLOC_FROM_POOL) ? size : NGX_MAX_ALLOC_FROM_POOL\u003c/code\u003e，其中 \u003ccode\u003eNGX_MAX_ALLOC_FROM_POOL\u003c/code\u003e 在 \u003ccode\u003esrc/core/ngx_palloc.h\u003c/code\u003e 中定义为 \u003ccode\u003engx_pagesize - 1\u003c/code\u003e，而 \u003ccode\u003engx_pagesize\u003c/code\u003e 在 \u003ccode\u003esrc/os/unix/ngx_posix_init.c\u003c/code\u003e 中通过 \u003ccode\u003egetpagesize()\u003c/code\u003e 获取（在 x86/Linux 上通常为 4096，故阈值为 4095 字节）。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e为何阈值取一页\u003c/strong\u003e：大于一页的内存在物理上不一定是连续的，所以如果分配的内存大于一页，从内存池中使用和向操作系统重新申请，效率上差不多等价。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"参考\"

源于 Unix），语句由分号划分，代码层次使用花括号 \u003ccode\u003e{}\u003c/code\u003e 划分，但不必显式声明变量类型。\u003c/li\u003e\n\u003cli\u003e标量变量以 \u003ccode\u003e$\u003c/code\u003e 开头（如 \u003ccode\u003e$name\u003c/code\u003e），数组以 \u003ccode\u003e@\u003c/code\u003e 开头（如 \u003ccode\u003e@name\u003c/code\u003e），哈希以 \u003ccode\u003e%\u003c/code\u003e 开头（如 \u003ccode\u003e%name\u003c/code\u003e），这三类是类型标识符；文件句柄则没有特殊前缀。\u003c/li\u003e\n\u003cli\u003e哈希可以用列表来创建，但访问键值时使用花括号 \u003ccode\u003e{}\u003c/code\u003e 而非圆括号（这一点尤其需要注意）。\u003c/li\u003e\n\u003cli\u003e数值之间比较用 \u003ccode\u003e==\u003c/code\u003e、\u003ccode\u003e\u0026gt;=\u003c/code\u003e、\u003ccode\u003e\u0026lt;=\u003c/code\u003e、\u003ccode\u003e!=\u003c/code\u003e，字符串之间比较则用 \u003ccode\u003eeq\u003c/code\u003e、\u003ccode\u003egt\u003c/code\u003e、\u003ccode\u003elt\u003c/code\u003e、\u003ccode\u003ege\u003c/code\u003e、\u003ccode\u003ele\u003c/code\u003e。\u003c/li\u003e\n\u003cli\u003e\u003ccode\u003eprint\u003c/code\u003e 函数不一定需要括号，常见用法有：\u003ccode\u003eprint $name\u003c/code\u003e（直接输出标量）；\u003ccode\u003eprint '$name'\u003c/code\u003e（单引号原样输出，不会替换变量，基本不用）；\u003ccode\u003eprint \u0026quot;$name\u0026quot;\u003c/code\u003e（双引号会自动替换变量，常用）。注意：当 \u003ccode\u003eprint\u003c/code\u003e 用于向文件句柄输出时，句柄与列表之间不能用逗号，只能用空格分隔，例如 \u003ccode\u003eprint FH \u0026quot;hello\\n\u0026quot;;\u003c/code\u003e。\u003c/li\u003e\n\u003cli\u003e\u003ccode\u003e@_\u003c/code\u003e 是子程序接收参数的默认数组，可以从中取实参；\u003ccode\u003e$_\u003c/code\u003e 是默认变量，表示在不显式指定时程序正在处理的当前变量；\u003ccode\u003eshift\u003c/code\u003e 函数会将数组的第一个元素（即 \u003ccode\u003e$array[0]\u003c/code\u003e）移出并返回。\u003c/li\u003e\n\u003cli\u003e\u003ccode\u003eshift\u003c/code\u003e 函数缺省时操作 \u003ccode\u003e@_\u003c/code\u003e，因此常放在子程序开头用于接收参数，或放在文件开头用于接收命令行参数。\u003c/li\u003e\n\u003cli\u003e文件句柄与文件的关系：文件必须先打开并被赋予句柄，才能操作；某些句柄可直接使用，如 \u003ccode\u003eSTDIN\u003c/code\u003e、\u003ccode\u003eSTDOUT\u003c/code\u003e、\u003ccode\u003eSTDERR\u003c/code\u003e；广义上，标量变量也是一种代表数据的「句柄」。\u003c/li\u003e\n\u003cli\u003ePerl 中数值和字符串都可以使用递增（\u003ccode\u003e++\u003c/code\u003e）和递减（\u003ccode\u003e--\u003c/code\u003e）运算符。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"perl-模块安装\" class=\"headerLink\"\u003e\n \u003ca

Laravel、Symfony）而言，这部分引导开销常常是毫秒级的，在 QPS 较高时成为瓶颈。\u003c/p\u003e\n\u003cp\u003ePHP 生态内部对此给出了几种答案:Swoole、ReactPHP、FrankenPHP、RoadRunner 等。其中 RoadRunner 的特别之处在于，它\u003cstrong\u003e把进程调度与网络 I/O 完全交给 Go 完成\u003c/strong\u003e,PHP 只负责执行业务代码。这种分工的好处是:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003eGo 的 goroutine 模型在网络 I/O 多路复用上非常高效;\u003c/li\u003e\n\u003cli\u003eGo 可以同时承担

Go 与 PHP 之间的二进制 IPC(进程间通信)协议，负责把请求帧从 Go 端投递到 PHP 端，再把响应回传。\u003c/li\u003e\n\u003c/ol\u003e\n\u003cp\u003e请求进来时，Go 主进程不是去 fork 一个新的 PHP 进程，而是把请求通过 Goridge 协议交给池子里一个空闲的 PHP worker;worker 处理完后回到等待状态，继续服务下一个请求。框架引导只在 worker 启动时发生一次，后续成千上万个请求都直接复用。\u003c/p\u003e\n\u003cp\u003e这种「常驻 worker + 进程隔离」的设计还有两个工程上的好处:\u003cstrong\u003e单个 worker 崩溃不会影响其他 worker\u003c/strong\u003e(supervisor 会自动重启),并且\u003cstrong\u003e水平扩展非常直接\u003c/strong\u003e——只要把 \u003ccode\u003enum_workers\u003c/code\u003e 调大即可。\u003c/p\u003e\n\u003ch2 id=\"goridgego-与-php-之间的二进制桥梁\" class=\"headerLink\"\u003e\n

\u003ccode\u003ePTRACE_O_TRACECLONE\u003c/code\u003e,内核会在新线程被 \u003ccode\u003eclone\u003c/code\u003e 出来的瞬间发送 \u003ccode\u003ePTRACE_EVENT_CLONE\u003c/code\u003e 事件,tracer 通过

对象并通过请求上下文传递到下游路由——但 FastAPI 并不原生支持这种\u0026quot;中间件注入请求级对象\u0026quot;的模式。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e记录 uvicorn 的日志\u003c/strong\u003e。把 uvicorn 自身的 access log

类型的分数。Redis 正是通过分数来为集合中的成员进行从小到大的排序。\u003c/p\u003e\n\u003cp\u003eZset 的成员是唯一的，但分数（score）却可以重复。\u003c/p\u003e\n\u003cp\u003e关于为什么起名 Zset，社区里有两种解释:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e前面的 Z 代表的是 XYZ 中的 Z,Zset 是在说这是比 Set 多了一个维度的 Set。\u003c/li\u003e\n\u003cli\u003eZ 正好排在英文字母表中的最后一个，表示里面的元素都是类似于 \u0026hellip;X、Y、Z 这样按顺序排列的，所以叫 ZSET。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2

是一种基数估算算法。所谓基数估算，就是估算在一批数据中，不重复元素的个数有多少。\u003c/p\u003e\n\u003cp\u003e从数学上来说，基数估计这个问题的详细描述是：对于一个数据流 {x1, x2, \u0026hellip;, xs} 而言，它可能存在重复的元素，用 n 来表示这个数据流的不同元素的个数，并且这个集合可以表示为 {e1, \u0026hellip;, en}。目标是：使用 m 这个量级的存储单位，可以得到 n 的估计值，其中 m 远小于 n，并且估计值和实际值 n 的误差是可以控制的。\u003c/p\u003e\n\u003cp\u003e对于上面这个问题，如果想得到精确的基数，可以使用字典（dictionary）这一数据结构。对于新来的元素，可以查看它是否属于这个字典;如果属于，则整体计数保持不变;如果不属于，则先把元素添加进字典，然后把整体计数加一。当遍历完整个数据流之后，得到的整体计数就是这个数据流的基数了。\u003c/p\u003e\n\u003cp\u003e这种算法虽然精准度很高，但是使用的空间复杂度也很高。那么是否存在一些近似的方法，可以估算出数据流的基数呢?HyperLogLog 就是这样一种算法，既能以较低的空间复杂度完成估算，最后得到的误差又是可以接受的。\u003c/p\u003e\n\u003ch3 id=\"应用场景举例\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e5%ba%94%e7%94%a8%e5%9c%ba%e6%99%af%e4%b8%be%e4%be%8b\" class=\"header-mark\"\u003e\u003c/a\u003e应用场景举例\u003c/h3\u003e\u003cp\u003eHyperLogLog 的主要应用场景就是进行基数统计，而这类问题的实际需求其实非常广泛。\u003c/p\u003e\n\u003cp\u003e例如，对于 Google 主页面而言，同一个账户可能会多次访问。于是在诸多的访问流水中，如何计算出 Google 主页面每天被多少个不同的账户访问过就是一个重要的问题。对于 Google 这种访问量巨大的网页而言，统计出十亿的访问量或十亿零十万的访问量其实并没有太大区别。因此，在这种业务场景下，为了节省成本，其实只需要计算出一个大概的值，而没有必要计算出精准的值。\u003c/p\u003e\n\u003cp\u003e对于上面的场景，可以使用 HashMap、BitMap 和 HyperLogLog 来解决。下面对这三种方案做一个简单对比:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eHashMap\u003c/strong\u003e:算法简单，统计精度高，对于少量数据建议使用;但对于大量数据会占用很大的内存空间。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eBitMap\u003c/strong\u003e:位图算法，统计精度高，虽然内存占用比 HashMap 少，但对于大量数据仍然会占用较大内存。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eHyperLogLog\u003c/strong\u003e:存在一定误差，标准误差约为 0.81%;内存占用稳定，最多约 12 KB，最多可统计 2^64 个元素，适合上述应用场景。\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"stream\" class=\"headerLink\"\u003e\n \u003ca href=\"#stream\" class=\"header-mark\"\u003e\u003c/a\u003eStream\u003c/h2\u003e\u003cp\u003eRedis Stream 是 Redis 5.0 版本新增的数据结构。\u003c/p\u003e\n\u003cp\u003eRedis Stream 主要用于消息队列（MQ,Message Queue）。Redis 本身提供了发布订阅（Pub/Sub）模式来实现消息队列的功能，但它有一个缺点：消息无法持久化，如果出现网络断开、Redis 宕机等情况，消息就会被丢弃。\u003c/p\u003e\n\u003cp\u003e简单来说，发布订阅（Pub/Sub）可以分发消息，但无法记录历史消息。\u003c/p\u003e\n\u003cp\u003e而 Redis Stream 提供了消息的持久化和主备复制功能，可以让任何客户端访问任何时刻的数据，并且能记住每一个客户端的访问位置，还能保证消息不丢失。\u003c/p\u003e\n\u003cp\u003eStream 提供的功能可以类比其他消息队列中间件，如 Kafka。\u003c/p\u003e\n\u003ch2 id=\"参考链接\" class=\"headerLink\"\u003e\n \u003ca

中运行；下次接入（attach）即可回到原来的工作现场。这种\u0026quot;会话持久化\u0026quot;是 Tmux 最常被使用的特性。它的另一个价值是\u0026quot;多任务分屏\u0026quot;：在一个屏幕内同时观察日志、编辑代码、运行命令，靠窗口（window）与窗格（pane）的组合实现。\u003c/p\u003e\n\u003cp\u003eGNU Screen 提供了类似能力，但 Tmux 在配置、状态栏、窗格管理等方面更现代；社区中 byobu 以 Tmux 为后端做了开箱即用的封装，zellij 则是更年轻的设计。\u003c/p\u003e\n\u003ch2 id=\"层级模型session--window--pane\" class=\"headerLink\"\u003e\n \u003ca

有两层含义：\n对 client（客户端）透明：客户端无需任何额外配置，既不必修改请求地址，也不必采用代理协议与代理服务器协商。相比之下，socks 或 http 代理都需要在客户端显式设置代理地址，并在发起请求时通过代理协议告知代理服务器真实的目标地址。 对 server（服务端）透明：服务端看到的是 client 端的地址，而非 proxy 的地址，仿佛请求从未经过中转。 换句话说，在一条透明的链路里，两端都不知道代理的存在。这与传统代理协议（如 HTTP CONNECT、SOCKS5）形成鲜明对比，后者要求应用感知代理并主动与之交互。\n", "author" : { "name" : "小智晖" }, "content_html" : "\u003ch2 id=\"什么是透明代理\" class=\"headerLink\"\u003e\n \u003ca

有两层含义：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e对 client（客户端）透明\u003c/strong\u003e：客户端无需任何额外配置，既不必修改请求地址，也不必采用代理协议与代理服务器协商。相比之下，socks 或 http 代理都需要在客户端显式设置代理地址，并在发起请求时通过代理协议告知代理服务器真实的目标地址。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e对 server（服务端）透明\u003c/strong\u003e：服务端看到的是 client 端的地址，而非 proxy 的地址，仿佛请求从未经过中转。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e换句话说，在一条透明的链路里，两端都不知道代理的存在。这与传统代理协议（如 HTTP CONNECT、SOCKS5）形成鲜明对比，后者要求应用感知代理并主动与之交互。\u003c/p\u003e\n\u003ch2 id=\"透明代理的实现思路\"

class=\"header-mark\"\u003e\u003c/a\u003e透明代理的实现思路\u003c/h2\u003e\u003cp\u003e实现透明代理有两种典型方式：\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003e基于 NAT（Network Address Translation）的方案\u003c/strong\u003e：使用 iptables 的 \u003ccode\u003eREDIRECT\u003c/code\u003e 或 \u003ccode\u003eDNAT\u003c/code\u003e 目标改写数据包的目的地址，将流量转发到本地代理端口。这种方式实现简单，但会改写包头，代理无法直接获取原始目的地址。对 UDP 而言恢复原始地址尤其困难，对 TCP 也存在竞态问题。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eTPROXY 内核模块\u003c/strong\u003e：Linux 内核从 2.2 时代起就支持透明代理，当前实现位于 \u003ccode\u003ext_TPROXY\u003c/code\u003e 模块中。它不依赖 NAT，在 mangle 表的 \u003ccode\u003ePREROUTING\u003c/code\u003e 链上把数据包打上 mark（标记）并交给本地 socket，从而完整保留原始的源地址和目的地址。\u003c/li\u003e\n\u003c/ol\u003e\n\u003cp\u003e由于 TPROXY 不改写包头，代理进程可以直接从拦截到的 socket 上读到原始目的地址，再决定如何转发。这也是 Istio Ambient、Squid、V2Ray/Xray 等项目优先选择 TPROXY 的根本原因。\u003c/p\u003e\n\u003ch2 id=\"tproxy-的工作原理\" class=\"headerLink\"\u003e\n \u003ca

会帮助你生成一个静态网站来展示它们。\u003c/p\u003e\n\u003cp\u003eVuePress 诞生的初衷是为了支持 Vue.js 及其子项目的文档需求，不过现在它已经在帮助大量用户构建他们的文档、博客和其他静态网站。\u003c/p\u003e\n\u003ch2 id=\"实现原理\" class=\"headerLink\"\u003e\n \u003ca

驱动的单页面应用（SPA）。\u003c/p\u003e\n\u003cp\u003e路由会根据 Markdown 文件的相对路径自动生成。每个 Markdown 文件都会通过 markdown-it 编译为 HTML，然后将其作为 Vue 组件的模板。因此，你可以在 Markdown 文件中直接使用 Vue 语法，便于嵌入一些动态内容。\u003c/p\u003e\n\u003cp\u003e在开发过程中，VuePress 会启动一个常规的开发服务器（dev-server），并将站点作为一个常规的 SPA 运行。如果你以前使用过 Vue，那么在使用时会感受到非常熟悉的开发体验。\u003c/p\u003e\n\u003cp\u003e在构建过程中，VuePress 会为站点创建一个服务端渲染（SSR）的版本，然后通过虚拟访问每一条路径来渲染对应的 HTML。这种做法的灵感来源于 Nuxt 的 \u003ccode\u003enuxt generate\u003c/code\u003e 命令，以及其他的一些项目，比如 Gatsby。\u003c/p\u003e\n\u003ch2 id=\"与其它静态网站生成器的对比\"

Nuxt\u003c/h3\u003e\u003cp\u003eNuxt 是一套出色的 Vue SSR 框架，VuePress 能做的事情，Nuxt 实际上也同样能够胜任。但 Nuxt 是为构建应用程序而生的，而 VuePress 则更为轻量化，并且专注在以内容为中心的静态网站上。\u003c/p\u003e\n\u003ch3 id=\"2-vitepress\" class=\"headerLink\"\u003e\n \u003ca href=\"#2-vitepress\" class=\"header-mark\"\u003e\u003c/a\u003e2. VitePress\u003c/h3\u003e\u003cp\u003eVitePress 是 VuePress 的\u0026quot;孪生兄弟\u0026quot;，最初同样由 Vue.js 作者 Evan You 创建。如今 VuePress 1.x 已被官方弃用，Vue 团队决定长期专注于 VitePress，而 VuePress 2 则交由 VuePress 社区团队维护。\u003c/p\u003e\n\u003cp\u003eVitePress 基于 Vite 与 Vue 3 构建，相比 VuePress 更轻、更快，但在灵活性和可配置性上作出了一些让步——它没有 VuePress 那样完整的插件系统，而是通过深度集成 Vite 的插件生态来提供扩展能力。当然，如果你没有进阶的定制化需求，VitePress 已经足够支持你将内容部署到线上。\u003c/p\u003e\n\u003cp\u003e这个比喻可能不是很恰当，但是你可以把 VuePress 和 VitePress 的关系看作 Laravel 和 Lumen。\u003c/p\u003e\n\u003ch3 id=\"3-docsify--docute\" class=\"headerLink\"\u003e\n \u003ca href=\"#3-docsify--docute\" class=\"header-mark\"\u003e\u003c/a\u003e3. Docsify / Docute\u003c/h3\u003e\u003cp\u003e这两个项目同样都是基于 Vue，然而它们都是完全的运行时驱动，因此对 SEO 不够友好。如果你并不关注 SEO，同时也不想安装大量依赖，它们仍然是非常好的选择。\u003c/p\u003e\n\u003ch3 id=\"4-hexo\" class=\"headerLink\"\u003e\n \u003ca href=\"#4-hexo\" class=\"header-mark\"\u003e\u003c/a\u003e4. Hexo\u003c/h3\u003e\u003cp\u003eHexo 曾经驱动着 Vue 2.x 的文档。Hexo 最大的问题在于它的主题系统过于静态，并且过度依赖纯字符串模板，而我们十分希望能够利用 Vue 来处理布局和交互。同时，Hexo 在配置 Markdown 渲染方面的灵活性也不是最佳的。\u003c/p\u003e\n\u003ch3 id=\"5-gitbook\" class=\"headerLink\"\u003e\n \u003ca href=\"#5-gitbook\" class=\"header-mark\"\u003e\u003c/a\u003e5. GitBook\u003c/h3\u003e\u003cp\u003e过去我们的子项目文档一直都在使用 GitBook。GitBook 最大的问题在于当文件很多时，每次编辑后的重新加载时间长得令人无法忍受。它的默认主题导航结构也比较有限制性，并且主题系统也不是 Vue 驱动的。GitBook 背后的团队如今也更专注于将其打造为商业产品，而不是开源工具。\u003c/p\u003e\n\u003ch2 id=\"参考\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e5%8f%82%e8%80%83\"

jQuery、Lodash。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e框架\u003c/strong\u003e:框架负责调度生命周期和渲染流程，开发者在框架规定的位置（如组件、路由、配置文件）填充业务代码。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e据此，React 严格意义上是一个「用于构建用户界面的 JavaScript 库」,而 Next.js、ice.js 才是在它之上封装了路由、构建、SSR/SSG 等约定的「框架」。本文沿用社区习惯，把 React、Vue 这类 UI 基础库也泛称为「框架」。\u003c/p\u003e\n\u003ch2 id=\"react现代前端生态的基石\" class=\"headerLink\"\u003e\n

处于同一个生态位，承担系统编程、嵌入式、编译器底层、高性能服务等场景，但用现代语言的语法和工程实践重新打磨了 C 留下的旧问题。维基百科将其归纳为「命令式、通用、静态类型、编译型的系统编程语言」，并明确「旨在替代 C」。\u003c/p\u003e\n\u003ch2 id=\"为什么需要又一门系统语言\" class=\"headerLink\"\u003e\n \u003ca

等）选择在 C 之上抽象出更厚的运行时或更复杂的类型系统来缓解这些问题。\u003c/p\u003e\n\u003cp\u003eZig 走了另一条路：\u003cstrong\u003e不引入隐藏机制，把所有显式的成本暴露给程序员，同时用语言内置能力替代 C 中需要靠约定或外部工具才能做到的事情\u003c/strong\u003e。它没有垃圾回收（GC）、没有宏、没有预处理器、没有运算符重载、没有隐式函数调用；但提供了编译期求值、显式分配器、错误作为值、可选类型等现代特性。结果是代码「所见即所执行」，调试时不用先去理解语言本身。\u003c/p\u003e\n\u003ch2 id=\"核心设计哲学\"

条核心原则，真正重要的是这些原则，技术栈只是落实它们的方法。你如果不熟悉某个技术栈，不需要过度担心。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e（3）工作和人际关系是两回事。有一些公司，我交到了好朋友，但是工作得并不开心;另一些公司，我没有与任何同事建立友谊，但是工作得很开心。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e（4）我总是对经理实话实说。怕什么？他开除我？我会在两周内找到一份新工作。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e（5）如果一家公司的工程师超过

Java。这是一种糟糕的编程语言，但几乎无所不能。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e（13）对初学者来说，最赚钱的编程语言是 SQL，干翻所有其他语言。你只了解 SQL 而不会做其他事情，照样赚钱。一个普通的薪资专员（payroll specialist）年薪？也许 5 万美元。懂 SQL 的薪资专员？9

养老金听起来不错，但是你将被禁锢在深奥的专用工具里面，离开政府单位以后，这些知识就没用了。我非常尊重政府工作人员，但说真的，这些地方的工程师年龄中位数在 50 岁以上，是有原因的。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e（16）再倒一杯酒。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e（17）大多数头衔都无关紧要，随便什么公司都可以有首席工程师。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e（18）手腕和背部的健康问题可不是开玩笑的，好的设备值得花钱。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e（19）当一个软件工程师，最好的事情是什么？你可以结识很多想法相同的人，大家互相交流，不一定有相同的兴趣，但是对方会用跟你相同的方式思考问题，这很酷。\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e（20）有些技术太流行，我不得不用它。我心里就会很讨厌这种技术，但会把它推荐给客户。比如我恨

100%，也不能保证用户场景完全被覆盖到或不会出现漏测——从原理上讲，代码覆盖率只能表示开发写的代码都执行了，但并不表示代码没有逻辑问题，例如漏写异常处理、没有完全覆盖用户场景等。\u003c/p\u003e\n\u003ch2 id=\"lcovinfo-格式解析\" class=\"headerLink\"\u003e\n \u003ca

生成，仅供参考）：\u003c/p\u003e\n\u003cblockquote\u003e\n \u003cp\u003e全量代码覆盖率、增量代码覆盖率和累计代码覆盖率是衡量软件测试质量的重要指标，下面对这三种覆盖率进行详细解释。\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e全量代码覆盖率\u003c/strong\u003e：指在整个代码库中，经过测试用例执行后实际被执行的代码行数与总代码行数的比例，通常用于评估整个项目或模块的测试充分性。一般要求达到 70% 至 80% 之间，以确保大部分代码路径都经过测试。\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e增量代码覆盖率\u003c/strong\u003e：指在特定版本或迭代中新增或修改的代码行被测试用例覆盖的比例，主要用于评估每次迭代对新代码的测试情况。通常要求更高，服务端项目可能要求 80%-90%，而移动端和前端项目则要求 70%-80%，这种高标准确保了新功能或修复的可靠性。\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e累计代码覆盖率\u003c/strong\u003e：指在整个开发周期内，所有版本中被测试用例执行过的代码行数与总代码行数的比例，反映了随着时间推移项目整体的测试情况。通常会随着项目的发展而提高，开发团队会设定阶段性目标，例如核心业务代码分支覆盖率达到 50% 或更高。\u003c/p\u003e\n\u003cp\u003e总结：这三种覆盖率各有侧重——全量代码覆盖率关注整体质量，增量代码覆盖率强调新功能的可靠性，累计代码覆盖率则反映长期的测试成果。通过合理设置这些指标，可以有效提升软件质量并降低潜在风险。\u003c/p\u003e\n\n\u003c/blockquote\u003e\u003ch2 id=\"平台\"

version 是一个特定的App版本。 AppVersion = Platform + VersionNumber + version.xml + Input/Output Templates。\u003c/p\u003e\n\u003cp\u003eBOINC 支持如下三种模式的App：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003eNative app: add BOINC API calls to the program source code, then compile it (for a given platform) and link it to the BOINC runtime library.\u003c/li\u003e\n\u003cli\u003eWrapper: use a BOINC-supplied program (wrapper) that interfaces between the BOINC client and an unmodified executable. This removes the need to change your program\u0026rsquo;s source code, but you still need to build it for different platforms (e.g. Windows).\u003c/li\u003e\n\u003cli\u003eVM apps: your app runs inside a virtual machine (typically Linux). A BOINC-supplied program called vboxwrapper interfaces between the BOINC client, VirtualBox, and the VM.\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"最佳实践\" class=\"headerLink\"\u003e\n \u003ca

可以打包后采用第三方云存储如cos进行管理， 本地实现一个定时脚本，定时检测如果由最新AppVersion则拉取到本地，然后进行签名、更新等操作。\u003c/p\u003e\n\u003cp\u003e任务单元的创建，虽然Boinc官方提供了python远程提交等方式，但是使用起来很麻烦。官方也没有说明 Python 库要如何安装。我认为这里不如自己封装一个HTTP API来实现远程调用，可以部署一个 WebHook Server 如：\u003ca href=\"https://github.com/adnanh/webhook\" target=\"_blank\" rel=\"noopener noreferrer\"\u003egolang webhook\u003c/a\u003e, 来实现远程调用命令行。\n这样也几乎是不用开发，通过配置即可实现。\u003c/p\u003e\n\u003ch2 id=\"示例\" class=\"headerLink\"\u003e\n \u003ca href=\"#%e7%a4%ba%e4%be%8b\"

java.util.Arrays#asList()。\u003c/li\u003e\n\u003cli\u003e桥接模式：这个模式将抽象和抽象操作的实现进行了解耦，这样使得抽象和实现可以独立地变化，如JDBC；\u003c/li\u003e\n\u003cli\u003e组合模式：使得客户端看来单个对象和对象的组合是同等的。换句话说，某个类型的方法同时也接受自身类型作为参数，如 Map.putAll，List.addAll、Set.addAll。\u003c/li\u003e\n\u003cli\u003e装饰者模式：动态的给一个对象附加额外的功能，这也是子类的一种替代方式，如 java.util.Collections#checkedList|Map|Set|SortedSet|SortedMap。\u003c/li\u003e\n\u003cli\u003e享元模式：使用缓存来加速大量小对象的访问时间，如 valueOf(int)。\u003c/li\u003e\n\u003cli\u003e代理模式：代理模式是用一个简单的对象来代替一个复杂的或者创建耗时的对象，如

java.util.Calendar#getInstance()。\u003c/li\u003e\n\u003cli\u003e建造模式(Builder)：定义了一个新的类来构建另一个类的实例，以简化复杂对象的创建，如：java.lang.StringBuilder#append()。\u003c/li\u003e\n\u003cli\u003e工厂方法：就是 \u003cstrong\u003e一个返回\u003c/strong\u003e具体对象的方法，而不是多个，如 java.lang.Object#toString()、java.lang.Class#newInstance()。\u003c/li\u003e\n\u003cli\u003e原型模式：使得类的实例能够生成自身的拷贝、如：java.lang.Object#clone()。\u003c/li\u003e\n\u003cli\u003e单例模式：全局只有一个实例，如 java.lang.Runtime#getRuntime()。\u003c/li\u003e\n\u003c/ul\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e行为模式：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e责任链模式：通过把请求从一个对象传递到链条中下一个对象的方式，直到请求被处理完毕，以实现对象间的解耦。如 javax.servlet.Filter#doFilter()。\u003c/li\u003e\n\u003cli\u003e命令模式：将操作封装到对象内，以便存储，传递和返回，如：java.lang.Runnable。\u003c/li\u003e\n\u003cli\u003e解释器模式：定义了一个语言的语法，然后解析相应语法的语句，如，java.text.Format，java.text.Normalizer。\u003c/li\u003e\n\u003cli\u003e迭代器模式：提供一个一致的方法来顺序访问集合中的对象，如 java.util.Iterator。\u003c/li\u003e\n\u003cli\u003e中介者模式：通过使用一个中间对象来进行消息分发以及减少类之间的直接依赖，java.lang.reflect.Method#invoke()。\u003c/li\u003e\n\u003cli\u003e空对象模式：如 java.util.Collections#emptyList()。\u003c/li\u003e\n\u003cli\u003e观察者模式：它使得一个对象可以灵活的将消息发送给感兴趣的对象，如 java.util.EventListener。\u003c/li\u003e\n\u003cli\u003e模板方法模式：让子类可以重写方法的一部分，而不是整个重写，如

Context）：阐述子域之间的关系，可以简单理解成一个子系统或组件模块。\u003c/li\u003e\n\u003cli\u003e领域模型（Domain Model）：DDD的核心是建立（用通用描述语言、工具—领域通用语言）正确的领域模型；反应业务需求的本质，包括实体和过程；其贯穿软件分析、设计、开发 的整个过程；常用表达领域模型的方式：图、代码或文字；\u003c/li\u003e\n\u003cli\u003e领域通用语言：领域专家、开发设计人员都能理解的语言或工具。\u003c/li\u003e\n\u003cli\u003e经典分层架构：用户界面/展示层、应用层、领域层、基础设施层，是四层架构模式。\u003c/li\u003e\n\u003cli\u003e使用的模式：\n\u003cul\u003e\n\u003cli\u003e关联尽量少，尽量单项，尽量降低整体复杂度。\u003c/li\u003e\n\u003cli\u003e实体（Entity）：领域中的唯一标示，一个实体的属性尽量少，少则清晰。\u003c/li\u003e\n\u003cli\u003e值对象（Value Object）：没有唯一标识，且属性值不可变，小而简单的对象，比如Date。\u003c/li\u003e\n\u003cli\u003e领域服务（Domain Service）： 协调多个领域对象，只有方法没有状态(不存数据)；可以分为应用层服务，领域层服务、基础层服务。\u003c/li\u003e\n\u003cli\u003e聚合及聚合根（Aggregate，Aggregate Root）：聚合定义了一组具有内聚关系的相关对象的集合；聚合根是对聚合引用的唯一元素；当修改一个聚合时，必须在事务级别；大部分领域模型中，有70%的聚合通常只有一个实体，30%只有2~3个实体；如果一个聚合只有一个实体，那么这个实体就是聚合根；如果有多个实体，那么我们可以思考聚合内哪个对象有独立存在的意义并且可以和外部直接进行交互；\u003c/li\u003e\n\u003cli\u003e工厂（Factory）：类似于设计模式中的工厂模式。\u003c/li\u003e\n\u003cli\u003e仓储（Repository）：持久化到DB，管理对象，且只对聚合设计仓储。\u003c/li\u003e\n\u003c/ul\u003e\n\u003c/li\u003e\n\u003c/ul\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003ca

Algorithm）\u003c/strong\u003e，使用两个栈（操作数栈与运算符栈）将中缀表达式转换为后缀表达式，再通过单栈完成求值。其大致流程：\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003e遇到数字直接压入操作数栈。\u003c/li\u003e\n\u003cli\u003e遇到左括号压入运算符栈。\u003c/li\u003e\n\u003cli\u003e遇到右括号，不断弹出运算符并参与计算，直到匹配到左括号。\u003c/li\u003e\n\u003cli\u003e遇到运算符，先弹出栈中优先级 \u003cstrong\u003e大于等于\u003c/strong\u003e（对右结合运算符如 \u003ccode\u003e^\u003c/code\u003e 则为

list）\u003c/strong\u003e 串起来：分配时从链头摘一个，回收时挂回链头。两次操作都是 O(1),且完全不涉及通用分配器内部的位图搜索、桶分裂、合并伙伴块等开销。\u003c/p\u003e\n\u003cp\u003e这一思路最经典的工程实现就是 Jeff Bonwick 在 1994 年为 SunOS 5.4 设计的 \u003cstrong\u003eSlab 分配器\u003c/strong\u003e(\u0026ldquo;The Slab Allocator: An Object-Caching Kernel Memory Allocator\u0026rdquo;,USENIX Summer

frps，注册若干「代理」（proxy）。\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e一个代理（proxy）描述了一条「内网服务 → frps 端口」的映射规则。frp 内置的代理类型包括 \u003ccode\u003etcp\u003c/code\u003e、\u003ccode\u003eudp\u003c/code\u003e、\u003ccode\u003ehttp\u003c/code\u003e、\u003ccode\u003ehttps\u003c/code\u003e、\u003ccode\u003estcp\u003c/code\u003e（带密钥的 TCP，用于受限分享）、\u003ccode\u003extcp\u003c/code\u003e（P2P 穿透）、\u003ccode\u003esudp\u003c/code\u003e、\u003ccode\u003etcpmux\u003c/code\u003e 等。\u003c/p\u003e\n\u003cp\u003e通过在公网节点上部署 frps，可以轻松地把内网服务穿透到公网，同时提供诸多专业特性：\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e多种传输协议\u003c/strong\u003e：客户端与服务端通信支持 TCP、KCP、QUIC、WebSocket、WSS（WebSocket over TLS）等多种协议，通过 \u003ccode\u003etransport.protocol\u003c/code\u003e 配置项切换。其中 KCP 在 UDP 上实现可靠传输，官方文档称可降低 30%—40% 的平均延迟，代价是多消耗 10%—20% 的带宽；QUIC 是基于 UDP

虚拟主机端口（\u003ccode\u003evhostHTTPPort\u003c/code\u003e / \u003ccode\u003evhostHTTPSPort\u003c/code\u003e）可与 \u003ccode\u003ebindPort\u003c/code\u003e 共用同一端口，多个服务通过域名或路由区分共享同一个对外端口。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eP2P 通信\u003c/strong\u003e：通过 \u003ccode\u003extcp\u003c/code\u003e 代理类型，流量可以不经过 frps 中转，直接在两端之间打洞，充分利用带宽资源（受 NAT 类型限制，不保证成功）。\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e客户端插件\u003c/strong\u003e：原生支持

create -f\u003c/code\u003e 应用。注意,IPVS 模式与 iptables 模式的部署细节略有不同:IPVS 模式下还需要把 kubelet 的 \u003ccode\u003e--cluster-dns\u003c/code\u003e 改为本地缓存地址。\u003c/p\u003e\n\u003cp\u003e需要注意的是,NodeLocal DNSCache 默认会把非集群域的查询直接转发到上游,可能绕过 CoreDNS 的 \u003ccode\u003erewrite\u003c/code\u003e 等逻辑。解决办法是把 NodeLocal DNSCache 的上游指向 CoreDNS 的 ClusterIP,而不是节点

AWS 8 核机器上 APISIX 的 QPS 可达 14 万，平均延迟约 0.2 ms。值得一提的是，APISIX 也提供多语言插件能力：除 Lua 外，还支持通过 RPC 编写 Java/Go/Python/Node.js 插件，或通过 Proxy-Wasm 用任意支持 Wasm SDK 的语言扩展。\u003c/p\u003e\n\u003ch3 id=\"kong\"
