 If you have used nginx, you may know that nginx supports hot update, which means you can update your nginx without stopping and restarting it. It serves old connections with old version, and accepts new connections with new version. Notice that hot compiling is different from hot update, where hot compiling is monitoring your source files and recompile them when the content changes, it requires stop and restart your applications, `bee start` is a tool for hot compiling.

 Some people says that hot update is not as useful as its cool name. In my opinion, this is absolutely necessary because zero-down server is our goal for our services. Even though sometimes some errors or hardware problems may occur, but it belongs to design of high availability, don't mix them up. Service update is a known issue, so we need to fix this problem.

+## How Beego support hot update?

 The basic principle of hot update: main process fork a process, and child process execute corresponding programs. So what happens? We know that after forked a process, main process will have all handles, data and stack, etc, but all handles are saved in `CloseOnExec`, so all copied handles will be closed when you execute it unless you clarify this, and we need child process to reuse the handle of `net.Listener`. Once a process calls exec functions, it is "dead", system replaces it with new code. The only thing it left is the process ID, which is the same number but it is a new program after executed.

 Therefore, the first thing we need to do is that let child process fork main process and through `os.StartProcess` to append files that contains handle that is going to be inherited.

 Remember when I was writing the book about how to build web applications with Go, I just wanted to tell people what were my valuable experiences with Go in web development, especially I have been working with PHP and Python for almost ten years. At first, I didn't realize that a small web framework can give great help to web developers when they are learning to build web applications in a new programming language, and it also helps people more by studying its source code. Finally, I decided to write a open source web framework called Beego as supporting materiel for my book.

 Then I started to design logic execution of Beego. Because Go and Python have somewhat similar, I referenced some ideas from tornado to design Beego. As you can see, there is no different between Beego and tornado in RESTful processing; they both use GET, POST or some other methods to implement RESTful.

 ## beego如何支持热升级
 ## beego如何支持热升级
 热升级的原理基本上就是：主进程fork一个进程，然后子进程exec相应的程序。那么这个过程中发生了什么呢？我们知道进程fork之后会把主进程的所有句柄、数据和堆栈继承过来、但是里面所有的句柄存在一个叫做CloseOnExec，也就是执行exec的时候，copy的所有的句柄都被关闭了，除非特别申明，而我们期望的是子进程能够复用主进程的net.Listener的句柄。一个进程一旦调用exec类函数，它本身就"死亡"了，系统把代码段替换成新的程序的代码，废弃原有的数据段和堆栈段，并为新程序分配新的数据段与堆栈段，唯一留下的，就是进程号，也就是说，对系统而言，还是同一个进程，不过已经是另一个程序了。
