Go Systems Programming

Overview of this book

Go is the new systems programming language for Linux and Unix systems. It is also the language in which some of the most prominent cloud-level systems have been written, such as Docker. Where C programmers used to rule, Go programmers are in demand to write highly optimized systems programming code. Created by some of the original designers of C and Unix, Go expands the systems programmers toolkit and adds a mature, clear programming language. Traditional system applications become easier to write since pointers are not relevant and garbage collection has taken away the most problematic area for low-level systems code: memory management. This book opens up the world of high-performance Unix system applications to the beginning Go programmer. It does not get stuck on single systems or even system types, but tries to expand the original teachings from Unix system level programming to all types of servers, the cloud, and the web.

Network Programming

In the previous chapter, we talked about developing web applications, talking to databases, and dealing with JSON data in Go.

The topic of this chapter is the development of Go applications that work over TCP/IP networks. In addition, you will learn how to create TCP and UDP clients and servers. The central Go package of this chapter will be the net package: most of its functions are quite low level and require a good knowledge of TCP/IP and its family of protocols.

However, have in mind that network programming is a huge theme that cannot be covered in a single chapter. This chapter will give you the foundational directions for how to create TCP/IP applications in Go.

More analytically, this chapter will talk about the following topics:

  • How TCP/IP operates
  • The net Go standard package
  • Developing TCP clients and servers
  • Programing UDP clients and servers
  • Developing...
