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.

Interprocess communication

Interprocess communication (IPC), putting it simply, is allowing Unix processes to talk to each other. Various techniques exist that allow processes and programs to talk to each other. The single most popular technique used in Unix systems is the pipe, which exists since the early Unix days. Chapter 8, Processes and Signals, will talk more about implementing Unix pipes in Go. Another form of IPC is Unix domain sockets, which will also be discussed in Chapter 8, Processes and Signals.

Chapter 12, Network Programming, will talk about another form of Interprocess communication, which is network sockets. Shared memory also exists, but Go is against the use of shared memory as a means of communication. Chapter 9, Goroutines - Basic Features, and Chapter 10, Goroutines - Advanced Features, will show various techniques that allow goroutines to communicate with...
