Rspack Debugging

Overview

This Skill guides you on how to capture the underlying crash state of Rspack (which is based on Rust). By using the LLDB debugger and Rspack packages with debug symbols, we can obtain detailed stack backtraces, which are crucial for pinpointing issues. The guides focus on non-interactive, automated debugging to easily capture backtraces.

Preparation

Before starting, please ensure your environment meets the requirements.

1. Install LLDB: You must install the LLDB debugger.

   • macOS: Run xcode-select --install
   • Linux: Install the lldb package (e.g., apt-get install lldb)
   • Detailed guide: references/lldb.md

2. Replace Debug Packages: Production packages like @rspack/core have debug symbols stripped. They must be replaced with the @rspack-debug/* series packages to see useful stack information.
