# 30天自制C++服务器
> 该教程是本人学生时代初学C++的历程，工作后已无精力写完剩下部分，回顾当年的代码有诸多不完美甚至瑕疵，有意愿者可以自由修改、开发、续写该项目。
先说结论：不管使用什么语言，一切后台开发的根基，是面向Linux的C/C++服务器开发。
几乎所有高并发服务器都是运行在Linux环境的，笔者之前也用Java、node写过服务器，但最后发现只是学会了一门技术、一门语言，而并不了解底层的基础原理。一个HTTP请求的过程，为什么可以实现高并发，如何控制TCP连接，如何处理好数据传输的逻辑等等，这些只有面向C/C++编程才能深入了解。
本教程模仿《30天自制操作系统》，面向零经验的新手，教你在30天内入门Linux服务器开发。本教程更偏向实践，将会把重点放在如何写代码上，而不会花太多的篇幅讲解背后的计算机基础原理，涉及到的地方会给出相应书籍的具体章节，但这并不代表这些理论知识不重要，事实上理论基础相当重要，没有理论的支撑，构建出一个高性能服务器是无稽之谈。
本教程希望读者：
- 熟悉C/C++语言
- 熟悉计算机网络基础，如TCP协议、socket原理等
- 了解基本的操作系统基础概念，如进程、线程、内存资源、系统调用等
学完本教程后，你将会很轻松地看懂muduo源码。
C/C++学习的一个难点在于初学时无法做出实际上的东西，没有反馈，程序都在黑乎乎的命令行里运行，不像web开发，可以随时看到自己学习的成果。本教程的代码都放在code文件夹里，每一天学习后都可以得到一个可以编译运行的服务器，不断迭代开发。
在code文件夹里有每一天的代码文件夹，进入该文件夹，使用`make`命令编译，会生成两个可执行文件，输入命令`./server`就能看到今天的学习成果！然后新建一个Terminal，然后输入`./client`运行客户端，与服务器交互。

select(2) indicates writability, use getsockopt(2) to read
the SO_ERROR option at level SOL_SOCKET to determine
whether connect() completed successfully (SO_ERROR is

attempt to find all problems, or to ensure that everything it does
find is legitimately a problem.

We do a small hack, which is to ignore //'s with "'s after them on the

Style checker for C/C++ source files.
This is a fork of the Google style checker with minor extensions.
The style guidelines this tries to follow are those in
https://google.github.io/styleguide/cppguide.html
Every problem is given a confidence score from 1-5, with 5 meaning we are
certain of the problem, and 1 meaning it could be a legitimate construct.
This will miss some errors, and is not a substitute for a code review.
To suppress false-positive errors of a certain category, add a
'NOLINT(category)' comment to the line. NOLINT or NOLINT(*)
suppresses errors of all categories on that line.
The files passed in will be linted; at least one file must be provided.
Default linted extensions are %s.
Other file types will be ignored.
Change the extensions with the --extensions flag.
Flags:
output=emacs|eclipse|vs7|junit
By default, the output is formatted to ease emacs parsing. Visual Studio
compatible output (vs7) may also be used. Further support exists for
eclipse (eclipse), and JUnit (junit). XML parsers such as those used
in Jenkins and Bamboo may also be used. Other formats are unsupported.
verbose=#
Specify a number 0-5 to restrict errors to certain verbosity levels.
Errors with lower verbosity levels have lower confidence and are more
likely to be false positives.
quiet
Don't print anything if no errors are found.
filter=-x,+y,...
Specify a comma-separated list of category-filters to apply: only
error messages whose category names pass the filters will be printed.
(Category names are printed with the message and look like
"[whitespace/indent]".) Filters are evaluated left to right.
"-FOO" and "FOO" means "do not print categories that start with FOO".
"+FOO" means "do print categories that start with FOO".
Examples: --filter=-whitespace,+whitespace/braces
--filter=whitespace,runtime/printf,+runtime/printf_format
--filter=-,+build/include_what_you_use
To see a list of all the categories used in cpplint, pass no arg:
--filter=
counting=total|toplevel|detailed
The total number of errors found is always printed. If
'toplevel' is provided, then the count of errors in each of
the top-level categories like 'build' and 'whitespace' will
also be printed. If 'detailed' is provided, then a count
is provided for each category like 'build/class'.
repository=path
The top level directory of the repository, used to derive the header
guard CPP variable. By default, this is determined by searching for a
path that contains .git, .hg, or .svn. When this flag is specified, the
given path is used instead. This option allows the header guard CPP
variable to remain consistent even if members of a team have different
repository root directories (such as when checking out a subdirectory
with SVN). In addition, users of non-mainstream version control systems
can use this flag to ensure readable header guard CPP variables.
Examples:
Assuming that Alice checks out ProjectName and Bob checks out
ProjectName/trunk and trunk contains src/chrome/ui/browser.h, then
with no --repository flag, the header guard CPP variable will be:
Alice => TRUNK_SRC_CHROME_BROWSER_UI_BROWSER_H_
Bob => SRC_CHROME_BROWSER_UI_BROWSER_H_
If Alice uses the --repository=trunk flag and Bob omits the flag or
uses --repository=. then the header guard CPP variable will be:
Alice => SRC_CHROME_BROWSER_UI_BROWSER_H_
Bob => SRC_CHROME_BROWSER_UI_BROWSER_H_
root=subdir
The root directory used for deriving header guard CPP variable.
This directory is relative to the top level directory of the repository
which by default is determined by searching for a directory that contains
.git, .hg, or .svn but can also be controlled with the --repository flag.
If the specified directory does not exist, this flag is ignored.
Examples:
Assuming that src is the top level directory of the repository (and
cwd=top/src), the header guard CPP variables for
src/chrome/browser/ui/browser.h are:
No flag => CHROME_BROWSER_UI_BROWSER_H_
--root=chrome => BROWSER_UI_BROWSER_H_
--root=chrome/browser => UI_BROWSER_H_
--root=.. => SRC_CHROME_BROWSER_UI_BROWSER_H_
linelength=digits
This is the allowed line length for the project. The default value is
80 characters.
Examples:
--linelength=120
recursive
Search for files to lint recursively. Each directory given in the list
of files to be linted is replaced by all files that descend from that
directory. Files with extensions not in the valid extensions list are
excluded.
exclude=path
Exclude the given path from the list of files to be linted. Relative
paths are evaluated relative to the current directory and shell globbing
is performed. This flag can be provided multiple times to exclude
multiple files.
Examples:
--exclude=one.cc
--exclude=src/*.cc
--exclude=src/*.cc --exclude=test/*.cc
extensions=extension,extension,...
The allowed file extensions that cpplint will check
Examples:
--extensions=%s
headers=x,y,...
The header extensions that cpplint will treat as .h in checks. Values are
automatically added to --extensions list.
(by default, only files with extensions %s will be assumed to be headers)
Examples:
--headers=%s
--headers=hpp,hxx
--headers=hpp
cpplint.py supports per-directory configurations specified in CPPLINT.cfg
files. CPPLINT.cfg file can contain a number of key=value pairs.
Currently the following options are supported:
set noparent
filter=+filter1,-filter2,...
exclude_files=regex
linelength=80
root=subdir
headers=x,y,...
"set noparent" option prevents cpplint from traversing directory tree
upwards looking for more .cfg files in parent directories. This option
is usually placed in the top-level project directory.
The "filter" option is similar in function to --filter flag. It specifies
message filters in addition to the |_DEFAULT_FILTERS| and those specified
through --filter command-line flag.
"exclude_files" allows to specify a regular expression to be matched against
a file name. If the expression matches, the file is skipped and not run
through the linter.
"linelength" allows to specify the allowed line length for the project.
The "root" option is similar in function to the --root flag (see example
above). Paths are relative to the directory of the CPPLINT.cfg.
The "headers" option is similar in function to the --headers flag
(see example above).
CPPLINT.cfg has an effect on files in the same directory and all
sub-directories, unless overridden by a nested configuration file.
Example file:
filter=-build/include_order,+build/include_alpha
exclude_files=.*\\.cc
The above example disables build/include_order warning and enables
build/include_alpha as well as excludes all .cc from being
processed by linter, in the current directory (where the .cfg
file is located) and all sub-directories.
