GDB Debugging for Chrome Blink Renderer Process

This source provides a comprehensive guide for using the GNU Debugger (GDB), primarily targeted at debugging the C++ code within the Chromium (Chrome) browser's renderer process (Blink) in a Linux development environment. The tutorial explains Chrome's complex multi-process architecture and outlines specific setup requirements, such as configuring debug symbols and disabling security restrictions like Yama ptrace scope and the browser's hang monitor. It details two main strategies for debugging: attaching GDB to a running renderer process (using flags like --renderer-startup-dialog) and launching the renderer under GDB control (using the --renderer-cmd-prefix flag). Finally, the guide covers essential GDB commands for execution control, state inspection (including backtraces and variables), handling multiple threads, and using specialized scripts and pretty-printers to navigate the enormous Chromium codebase effectively.
