Kernel Bug Heat Map Builder

This is a tool that scans git repos, extracts bug fix information from git commits, and aids in the analysis and visualization of that bug fix information.

This tool was orginally created for doing analysis on the Linux kernel; however, this tool can likely be adapted to do analysis on any git repo that includes bug fix information in commit messages in a sufficiently structured way.

How to use this tool

  1. Set your current working directory to the root of the git repo to be analyzed.
  2. Build the file to bug mapping:
    This builds the mapping between bugs and source files that subsequent analysis will be based on.
  3. Analyze the information, and vizualize the results: The supplies additional commands to do analysis on the file to bug mapping.
