Hands-On System Programming with Go

By: Alex Guerrieri

Overview of this book

System software and applications were largely created using low-level languages such as C or C++. Go is a modern language that combines simplicity, concurrency, and performance, making it a good alternative for building system applications for Linux and macOS. This Go book introduces Unix and systems programming to help you understand the components the OS has to offer, ranging from the kernel API to the filesystem. You'll then familiarize yourself with Go and its specifications. You'll also learn how to optimize input and output operations with files and streams of data, which are useful tools in building pseudo-terminal applications. You'll gain insights into how processes communicate with each other, and learn about processes and daemon control using signals, pipes, and exit codes. This book will also enable you to understand how to use network communication using various protocols, including TCP and HTTP. As you advance, you'll focus on Go's best feature - concurrency, which will help you handle communication with channels and goroutines, other concurrency tools to synchronize shared resources, and the context package to write elegant applications. By the end of this book, you will have learned how to build concurrent system applications using Go

Section 4: Deep Dive into Concurrency

This section focuses on one of the Go's most modern features—concurrency. It shows you the tools the language has, looks at sync and channels, and explains how and when to use each tool.

This section consists of the following chapters:

  • Chapter 11, Dealing with Channels and Goroutines
  • Chapter 12, Sync and Atomic Package
  • Chapter 13, Coordination Using Context
  • Chapter 14, Implementing Concurrency Patterns
