GoalsΒΆ

This project has two goals:

  1. To create a solid foundation for a long term performance analysis and profiling tool for PyPy.
  2. To explore new ways of visualization profiling and performance information.

To make these a reality, the following goals must be met:

  • The tracebin client must record useful information on the state of the program.
  • The tracebin client must be able to serialize the data and send it to the server.
  • The server must be able to store the data and display it (without any advanced visualization).
  • The server must be able to render a page of Python code interpolated with resops and machine code.
  • The server must be able to display a creative, novel, visualization of the data. What exactly this means is still up in the air. Some ideas for this are:
    • A density map of packages, modules, classes, and files based on JIT’d code.
    • An overlay of coverage data vs. trace data, showing what code is traced, but not covered by tests.

These more or less need to be completed in the order described.

There is also a likelihood that new features will need to be added to the JIT hooks, or new inspiration will be needed for the UI/UX/IA of the frontend. Luckily there are two exceptionally talented friends assisting:

  • Maciej Fijalkowski: PyPy core developer, and original developer of the JIT hooks.
  • Idan Gazit: Brilliant designer, and inspiration for some of the current UI.
