Introduction 8 | 9 | 本项目为C++11编写的Web服务器，解析了get、head请求，可处理静态资源，支持HTTP长连接，支持管线化请求，并实现了异步日志，记录服务器运行状态。 10 | 11 | 测试页：http://www.linya.pub/ 12 | 13 | 14 | | Part Ⅰ | Part Ⅱ | Part Ⅲ | Part Ⅳ | Part Ⅴ | Part Ⅵ | 15 | | :--------: | :---------: | :---------: | :---------: | :---------: | :---------: | 16 | | [并发模型](https://github.com/linyacool/WebServer/blob/master/并发模型.md)|[连接的维护](https://github.com/linyacool/WebServer/blob/master/连接的维护.md)|[版本历史](https://github.com/linyacool/WebServer/blob/master/%E7%89%88%E6%9C%AC%E5%8E%86%E5%8F%B2.md) | [测试及改进](https://github.com/linyacool/WebServer/blob/master/测试及改进.md) | [项目目的](https://github.com/linyacool/WebServer/blob/master/%E9%A1%B9%E7%9B%AE%E7%9B%AE%E7%9A%84.md) | [面试问题](https://github.com/linyacool/WebServer/blob/master/%E9%9D%A2%E8%AF%95%E9%97%AE%E9%A2%98.md) 17 | 18 | ## Envoirment 19 | * OS: Ubuntu 14.04 20 | * Complier: g++ 4.8 21 | 22 | ## Build 23 | 24 | ./build.sh 25 | 26 | ## Usage 27 | 28 | ./WebServer [-t thread_numbers] [-p port] [-l log_file_path(should begin with '/')] 29 | 30 | ## Technical points 31 | * 使用Epoll边沿触发的IO多路复用技术，非阻塞IO，使用Reactor模式 32 | * 使用多线程充分利用多核CPU，并使用线程池避免线程频繁创建销毁的开销 33 | * 使用基于小根堆的定时器关闭超时请求 34 | * 主线程只负责accept请求，并以Round Robin的方式分发给其它IO线程(兼计算线程)，锁的争用只会出现在主线程和某一特定线程中 35 | * 使用eventfd实现了线程的异步唤醒 36 | * 使用双缓冲区技术实现了简单的异步日志系统 37 | * 为减少内存泄漏的可能，使用智能指针等RAII机制 38 | * 使用状态机解析了HTTP请求,支持管线化 39 | * 支持优雅关闭连接 40 |   41 | ## Model 42 | 43 | 并发模型为Reactor+非阻塞IO+线程池，新连接Round Robin分配，详细介绍请参考[并发模型](https://github.com/linyacool/WebServer/blob/master/并发模型.md) 44 | ![并发模型](https://github.com/linyacool/WebServer/blob/master/datum/model.png) 45 | 46 | ##

/WebServerCpp11/WebServer/base/Log的设计.txt: -------------------------------------------------------------------------------- 1 | Log的设计仿照了muduo库的设计,但我写的没那么复杂 2 | https://github.com/chenshuo/muduo 3 | 4 | 与Log相关的类包括FileUtil、LogFile、AsyncLogging、LogStream、Logging。 5 | 其中前4个类每一个类都含有一个append函数，Log的设计也是主要围绕这个append函数展开的。 6 | 7 | FileUtil是最底层的文件类，封装了Log文件的打开、写入并在类析构的时候关闭文件，底层使用了标准IO，该append函数直接向文件写。 8 | LogFile进一步封装了FileUtil，并设置了一个循环次数，没过这么多次就flush一次。 9 | AsyncLogging是核心，它负责启动一个log线程，专门用来将log写入LogFile，应用了“双缓冲技术”，其实有4个以上的缓冲区，但思想是一样的。 10 | AsyncLogging负责(定时到或被填满时)将缓冲区中的数据写入LogFile中。 11 | LogStream主要用来格式化输出，重载了<<运算符，同时也有自己的一块缓冲区，这里缓冲区的存在是为了缓存一行，把多个<<的结果连成一块。 12 | Logging是对外接口，Logging类内涵一个LogStream对象，主要是为了每次打log的时候在log之前和之后加上固定的格式化的信息，比如打log的行、 13 | 文件名等信息。 14 |

改成写到不能写后或读到不能读后加入epoll等待，要记录写到哪或读到哪，维护这样一个状态。比较两者的性能差异。 4 | 4. 信号处理部分可以将 epoll_wait 替换为更安全的 epoll_pwait。 5 | 6 | 7 | 踩坑： 8 | 1. 对EPOLLONESHOT的误解，原以为当epoll_wait监听到相应的事件触发后，epoll会把与事件关联的fd从epoll描述符中禁止掉并且彻底删除，实际上并不会删除，man手册上的解释如下： 9 | EPOLLONESHOT (since Linux 2.6.2) 10 | Sets the one-shot behavior for the associated file descriptor. 11 | This means that after an event is pulled out with 12 | epoll_wait(2) the associated file descriptor is internally 13 | disabled and no other events will be reported by the epoll 14 | interface. The user must call epoll_ctl() with EPOLL_CTL_MOD 15 | to rearm the file descriptor with a new event mask. 16 | 另外： 17 | Linux Programmer's Manual 中第六个问题： 18 | Q6 Will closing a file descriptor cause it to be removed from all 19 | epoll sets automatically? 20 | 21 | A6 Yes, but be aware of the following point. A file descriptor is a 22 | reference to an open file description (see open(2)). Whenever a 23 | file descriptor is duplicated via dup(2), dup2(2), fcntl(2) 24 | F_DUPFD, or fork(2), a new file descriptor referring to the same 25 | open file description is created. An open file description con‐ 26 | tinues to exist until all file descriptors referring to it have 27 | been closed. A file descriptor is removed from an epoll set only 28 | after all the file descriptors referring to the underlying open 29 | file description have been closed (or before if the file descrip‐ 30 | tor is explicitly removed using epoll_ctl(2) EPOLL_CTL_DEL). 31 | This means that even after a file descriptor that is part of an 32 | epoll set has been closed, events may be reported for that file 33 | descriptor if other file descriptors referring to the same under‐ 34 | lying file description remain open. 35 | 36 | 当调用close()关闭对应的fd时，会使相应的引用计数减一，只有减到0时，epoll才会真的删掉它，所以，比较安全的做法是： 37 | 先del掉它，再close它(如果不确定close是否真的关闭了这个文件。)。 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | ubuntu 配置opencv： 52 | vim /etc/ld.so.conf 53 | 加一行include /usr/local/opencv/* 54 | /sbin/ldconfig –v -------------------------------------------------------------------------------- /WebServerCpp11/old_version/old_version_0.1/index.html: -------------------------------------------------------------------------------- 1 | Hello World ! -------------------------------------------------------------------------------- /WebServerCpp11/old_version/old_version_0.1/threadpool.h: -------------------------------------------------------------------------------- 1 | #ifndef THREADPOOL 2 | #define THREADPOOL 3 | #include "requestData.h" 4 | #include 5 | 6 | const int THREADPOOL_INVALID = -1;

The user must call epoll_ctl() with EPOLL_CTL_MOD 15 | to rearm the file descriptor with a new event mask. 16 | 另外： 17 | Linux Programmer's Manual 中第六个问题： 18 | Q6 Will closing a file descriptor cause it to be removed from all 19 | epoll sets automatically? 20 | 21 | A6 Yes, but be aware of the following point. A file descriptor is a 22 | reference to an open file description (see open(2)). Whenever a 23 | file descriptor is duplicated via dup(2), dup2(2), fcntl(2) 24 | F_DUPFD, or fork(2), a new file descriptor referring to the same 25 | open file description is created. An open file description con‐ 26 | tinues to exist until all file descriptors referring to it have 27 | been closed. A file descriptor is removed from an epoll set only 28 | after all the file descriptors referring to the underlying open 29 | file description have been closed (or before if the file descrip‐ 30 | tor is explicitly removed using epoll_ctl(2) EPOLL_CTL_DEL). 31 | This means that even after a file descriptor that is part of an 32 | epoll set has been closed, events may be reported for that file 33 | descriptor if other file descriptors referring to the same under‐ 34 | lying file description remain open. 35 | 36 | 当调用close()关闭对应的fd时，会使相应的引用计数减一，只有减到0时，epoll才会真的删掉它，所以，比较安全的做法是： 37 | 先del掉它，再close它(如果不确定close是否真的关闭了这个文件。)。 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | ubuntu 配置opencv： 52 | vim /etc/ld.so.conf 53 | 加一行include /usr/local/opencv/* 54 |

-------------------------------------------------------------------------------- 1 | # 测试及改进 2 | 3 | ## 测试环境 4 | * OS：Ubuntu 14.04 5 | * 内存：8G 6 | * CPU：I7-4720HQ 7 | 8 | ## 测试方法 9 | * 理想的测试环境是两台计算机，带宽无限，现在的网卡虽然都是千兆网卡，但是普通家用的网线都是5类双绞线，最高100Mbps,在linux下用ethtool可以看到网卡的速度被限制为100Mbsp，无法更改为更高的，经测试很容易跑满带宽，因此退而选择本地环境。 10 | * 使用工具Webbench，开启1000客户端进程，时间为60s 11 | * 分别测试短连接和长连接的情况 12 | * 关闭所有的输出及Log 13 | * 为避免磁盘IO对测试结果的影响，测试响应为内存中的"Hello World"字符加上必要的HTTP头 14 | * 我的最终版本中很多方面借鉴了muduo的思路，muduo中也提供了一个简单的HTTP echo测试，因此我将与muduo进行一个小小的对比，我修改了muduo测试的代码，使其echo相同的内容，关闭muduo的所有输出及Log 15 | * 线程池开启4线程 16 | * 因为发送的内容很少，为避免发送可能的延迟，关闭Nagle算法 17 | 18 | 19 | ## 测试结果及分析 20 | 测试截图放在最后 21 | 22 | | 服务器 | 短连接QPS | 长连接QPS | 23 | | - | :-: | -: | 24 | | WebServer | 126798| 335338 | 25 | | Muduo | 88430 | 358302 | 26 | 27 | * 首先很明显的一点是长链接能处理的请求数是短连接的三四倍，因为没有了连接建立和断开的开销，不需要频繁accept和shutdown\close等系统调用，也不需要频繁建立和销毁对应的结构体。 28 | * 我的服务器在最后的版本中，没有改进输入输出Buffer，用了效率低下的string，muduo用的是设计良好的vector，我将在后续改进这一点。这也造成了在长连接的情况下，我的server逊于muduo。虽说边沿触发效率高一点，但是还是比不过在Buffer上性能的优化的。 29 | * 短链接的情况下，我的服务器要超过Muduo很多。原因在于：Muduo采用水平触发方式(Linux下用epoll)，并且做法是每次Acceptor只accept一次就返回，面对突然的并发量，必然会因为频繁的epoll_wait耽误大量的时间，而我的做法是用while包裹accept，一直accept到不能再accept。当然，如果同时连接的请求很少，陈硕在书中也提到过，假如一次只有一个连接，那么我的方式就会多一次accpet才能跳出循环，但是这样的代价似乎微不足道啊，换来的效率却高了不少。 30 | * 空闲时，Server几乎不占CPU，短连接时，各线程的CPU负载比较均衡，长连接时，主线程负载0，线程池的线程负载接近100%，因为没有新的连接需要处理。各种情况均正常。 31 | * 没有严格的考证，测试时发现，HTTP的header解析的结果用map比用unordered_map快，网上的博客里有很多人做了测试，我在做实验的时候大致也发现了。主要是因为数据量太小，一个HTTP请求头才几个头部字段，建立unordered_map的成本要比map高，数据量小，复杂度根本体现不出来。 32 | 33 | 34 | 35 | ## 测试结果截图 36 | *

-------------------------------------------------------------------------------- 1 | # 版本历史 2 | 从0.1最初形成到一点一点改进到0.6，到最终看了muduo，痛下决心重写，最终的版本完全从头再来了，但有了前面的经验，写起来顺畅了不少，但花了比之前所有加起来还要长的时间 3 | ## 0.1 4 | 5 | 第一版是看了很多Github上别人写的服务器，以及博客上的一些总结，结合自己的理解写出来的。模型结构如下： 6 | 7 | * 使用了epoll边沿触发+EPOLLONESHOT+非阻塞IO 8 | * 使用了一个固定线程数的线程池 9 | * 实现了一个任务队列，由条件变量触发通知新任务的到来 10 | * 实现了一个小根堆的定时器及时剔除超时请求，使用了STL的优先队列来管理定时器 11 | * 解析了HTTP的get、post请求，支持长短连接 12 | * mime设计为单例模式 13 | * 线程的工作分配为： 14 | * 主线程负责等待epoll中的事件，并把到来的事件放进任务队列，在每次循环的结束剔除超时请求和被置为删除的时间结点 15 | * 工作线程阻塞在条件变量的等待中，新任务到来后，某一工作线程会被唤醒，执行具体的IO操作和计算任务，如果需要继续监听，会添加到epoll中 16 | 17 | * 锁的使用有两处： 18 | * 第一处是任务队列的添加和取操作，都需要加锁，并配合条件变量，跨越了多个线程。 19 | * 第二处是定时器结点的添加和删除，需要加锁，主线程和工作线程都要操作定时器队列。 20 | 21 | 22 | 23 | 第一版的服务器已经相对较完整了，该有的功能都已经具备了 24 | 25 | ## 0.2 26 | 27 | 在第一版的基础上，优化了代码结构，自己设计了RAII锁机制，使锁能够自动释放，并修复了一些小的bug 28 | 29 | ## 0.3 30 | 31 | * 几乎全部的裸指针被智能指针替代 32 | * 利用weak_ptr解决时间结点和HTTP类互指的问题 33 | * 任务队列的任务结构从函数指针+参数指针转换为C++11的function 34 | 35 | 这一版还是花了不少时间的，毕竟对象的生命周期不由自己控制了 36 | 37 | ## 0.4 38 | 39 | 这个时候买了陈硕的《Linux多线程服务端编程》书，看了一部分，从前面几章获得启发 40 | * 为不提供拷贝构造和赋值运算符的类添加了noncopyable基类 41 | * 重写了RAII机制的锁，学习muduo中的做法 42 | * 重写了单例模式，将双重加锁改为更简单而安全的pthread_once() 43 | 44 | ## 0.5 45 | 46 | * 修复了一些bug，稍微调整了类的结构 47 | * 封装了条件变量 48 | 49 | ## 0.6 50 | 51 | * 仿照muduo，写了4个缓冲区的异步Log日志，没有区分优先级，其它基本都具备了 52 | 53 | ## WebServer(重构) 54 | 55 | 不知道该给自己的服务器取什么名字好，随便叫个吧……最后一版被我改的面目全非，也是下了很大的决心。之前的版本无非修修补补，算是自我检讨的过程，但是闭门造车并不可取，于是我把陈硕的《Linux多线程服务端编程》看完了，书上虽然贴了部分源码，但我看的还是朦朦胧胧，很多地方不明白，花了几天时间把源码看了，不懂的地方再回过来看书，总算是弄明白了。看了大牛的代码，再看自己的……哎我重写总行了吧 56 | 57 | 顺便吐槽一下自己，之前在知乎上看到陈硕一直推销自己的书，我还觉得这人好功利，后来被师兄推荐，看了一下目录，觉得可以参考一下就买了。没想到书就一点一点这么看完了……还看了好几遍，源码也是看了好几遍…… 58 | 59 | 当然，这不是最终篇，可改进的地方还有很多，绝对不敢说看了几本书就敢说自己写的东西比大牛写的好，我还会继续改进自己的server的 60 | 61 | 最后版本的东西没有在这里介绍，写在了模型结构里，这里只想写一下自己的心路历程，记录一下小白成长之路～ -------------------------------------------------------------------------------- /WebServerCpp11/连接的维护.md: -------------------------------------------------------------------------------- 1 | # 连接维护(针对非阻塞IO) 2 | 3 | ### 建立连接 4 | 5 | * 建立连接的过程 6 | 连接的建立比较简单，server端通过socket()，bind()，listen()，并使用epoll ET模式监听listenfd的读请求，当TCP连接完成3次握手后，会触发listenfd的读事件，应用程序调用accept()，会检查已完成的连接队列，如果队列里有连接，就返回这个连接，出错或连接为空时返回-1。此时，已经可以进行正常的读写操作了。 当然，因为是ET模式，accept()要一直循环到就绪连接为空。 7 | * 分析 8 | 之所以说建立连接的过程比较简单，是因为数据的通信已经由操作系统帮我们完成了，这里的通信是指3次握手的过程，这个过程不需要应用程序参与，当应用程序感知到连接时，此时该连接已经完成了3次握手的过程，accept就好了。另一个原因是一般情况下，连接的建立都是client发起的，server端被动建立连接就好了，也不会出现同时建立的情况。 9 | * 限制 10 | 假设server只监听一个端口，一个连接就是一个四元组(原ip，原port，对端ip, 对端port)，那么理论上可以建立2^48个连接，可是，fd可没有这么多(操作系统限制、用户进程限制)。当连接满了，如果空等而不连接，那么就绪队列也满了后，会导致新连接无法建立。这里的做法我参考了muduo，准备一个空的文件描述符，accept()后直接close()，这样对端不会收到RST，至少可以知道服务器正在运行。 11 | 12 | ### 关闭连接 13 | 14 | 相对于连接的建立，关闭连接则复杂的多，远不是一个close()那么简单，关闭连接要优雅。 15 | 16 | ##### 什么时候关闭连接？ 17 | 通常server和client都可以主动发Fin来关闭连接 18 | 19 | * 对于client(非Keep-Alive)，发送完请求后就可以shutdown()写端，然后收到server发来的应答，最后close掉连接。也可以不shutdown()写，等读完直接close。对于Keep-Alive的情况，就要看client的心情了，收到消息后可以断，也可以不断，server应该保证不主动断开。 20 | 21 | * 对于server端，毫无疑问应该谨慎处理以上所有情况。具体说来: 22 | > * 出现各种关于连接的错误时，可以直接close()掉 23 | > * 短连接超时的请求，可以close()，也可以不关 24 | > * 长连接对方长时间没有请求(如果没有保活机制)，可以close()，也可以不关 25 | > * client发出Fin，server会收到0字节，通常不能判断client是close了还是shutdown，这时server应当把消息发完，然后才可以close()，如果对方调用的是close，会收到RST，server能感知到，就可以立即close了 26 | > * 短连接正常结束，server可以close，也可以不close，大多数的实现是不close的(对HTTP1.1而言) 27 | 28 | 29 | ##### EPOLLIN触发但是read()返回0的情况 30 | 31 | 这种情况通常有两个原因: 32 | > * 对端已经关闭了连接，这时再写该fd会出错，此时应该关闭连接 33 | > * 对端只是shutdown()了写端，告诉server我已经写完了，但是还可以接收信息。server应该在写完所有的信息后再关闭连接。更优雅的做法是透明的传递这个行为，即server顺着关闭读端，然后发完数据后关闭。 34 | -------------------------------------------------------------------------------- /WebServerCpp11/遇到的困难.md: -------------------------------------------------------------------------------- 1 | # 遇到的困难 2 | 3 | ## 1. 如何设计各个线程个任务 4 | 其实我觉的实现上的困难都不算真正的困难吧，毕竟都能写出来，无非是解决bug花的时间的长短。 5 | 我遇到的最大的问题是不太理解One loop per thread这句话吧，翻译出来不就是每个线程一个循环，我最开始写的也是一个线程一个循环啊，muduo的实现和我的有什么区别呢？还有怎么设计才能减少竞态？ 6 | 7 | 带着这些问题我看了《Linux多线程服务端编程》，并看完了muduo的源码，这些问题自然而然就解决了 8 | 9 | 10 | ## 2. 异步Log几秒钟才写一次磁盘，要是coredump了，这段时间内产生的log我去哪找啊？ 11 | 12 | 其实这个问题非常简单了，也没花多少时间去解决，但我觉的非常好玩。coredump了自然会保存在core文件里了，无非就是把它找出来的问题了，在这里记录一下。 13 | 14 | 当然这里不管coredump的原因是什么，我只想看丢失的log。所以模拟的话在某个地方abort()就行 15 | 16 | 多线程调试嘛，先看线程信息，info thread，找到我的异步打印线程，切换进去看bt调用栈，正常是阻塞在条件变量是wait条件中的，frame切换到threadFunc(这个函数是我的异步log里面的循环的函数名)，剩下的就是print啦～不过，我的Buffer是用智能指针shared_ptr包裹的，直接->不行，gdb不识别，优化完.get()不让用，可能被inline掉了，只能直接从shared_ptr源码中找到_M_ptr成员来打印。

-------------------------------------------------------------------------------- 1 | # 项目目的 2 | --- 3 | ### 最初的想法 4 | 本项目是我在三星电子(中国)研发中心实习期间利用晚上和周末的时间完成的，实习期间我负责4K分辨率双鱼眼摄像头视频拼接的算法设计与实现，我希望能把其中的图像拼接部分的成果通过Web的方式展示出来，但因为涉及保密协议，不得不放弃这一想法。 5 | 6 | ### Web服务器能够很好的贯穿所学的知识 7 | 但是，Web服务器能够很好的贯穿之前所学的知识，之前看过的《C++ Primer》、《Effevtive C++》、《STL源码剖析》、《深度探索C++对象模型》、《TCP\IP详解卷1》、APUE、UNP，还包括了《后台开发核心技术与应用实践》等书，涵盖了 8 | 9 | * TCP、HTTP协议 10 | * 多进程多线程 11 | * IO 12 | * 锁 13 | * 通信 14 | * C++语法 15 | * 编程规范 16 | * Linux环境下各种工具的使用 17 | * 版本控制Git 18 | * Makefile和CMakeLists文件的编写 19 | * 自动化构建工具Travis CI的使用 20 | 21 | 最终的版本在很多方面学习了muduo网络库，在看完陈硕的《Linux多线程服务端编程》后，对照着书把muduo的源码读了几遍，并重构了自己的服务器，最终的很多想法借鉴了muduo的思想。 22 |
