Read Original

This article explores fault injection techniques to trigger disk and filesystem errors in software. It focuses on using the ptrace debugging tool to intercept and modify Linux system calls, forcing 'short writes' to test error handling in programs written in Go, Python, and C. The tutorial includes practical code examples written in Zig for clarity.
