[Panic] Ruff VSCode extension crashes every time the word def is written in a class

[lmanc]

Hi, today while using the Ruff VSCode extension, Ruff crashed with the following message:

Ruff: Lint failed ( error: Ruff crashed. If you could open an issue at: https://github.com/astral-sh/ruff/issues/new?title=%5BPanic%5D ...quoting the executed command, along with the relevant file contents and `pyproject.toml` settings, we'd be very appreciative! thread 'main' panicked at D:\a\ruff\ruff\crates\ruff_text_size\src\range.rs:48:9: assertion failed: start.raw <= end.raw note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace )

I'm keeping the title as the message suggests. For the other parts:

• "quoting the executed command", since I'm using the VSCode extension, I'm not executing it via CLI. I'm uncertain about the "implicit" commands that are run under the hood.
• "relevant file contents", Ruff crashes every time I start writing a new function with the keyword def in this Django REST Framework view. I can't share the entire file, but here's an excerpt:

  # Imports and more classes above
  
  class WiseSettingsGroupsView(APIView):
      def get(self, request):
          # snip
          return Response(data)
          
      def serialize_data(self):
          # the function that make Ruff crash as soon as I type `def` here
          
  # Other classes

• "[...] and pyproject.toml settings", here they are:

  # Include Jupyter notebooks
  include = ["*.py", "*.pyi", "**/pyproject.toml", "*.ipynb"]
  
  # Exclude a variety of commonly ignored directories.

Thanks for opening the issue and the in detail description.

@dhruvmanila Is my assumption correct that this was probably fixed by #11032 ?

[lmanc]

I've noticed that it happens every time I use the keyword def in any class.

[lmanc]

And it crashes as soon as I type the space after def.

[dhruvmanila]

Yes, it's fixed on the latest extension version. Can you try it out? I can confirm it's not happening now.

[lmanc]

I updated the extension to v2024.20.0 and restarted all the extensions on VSCode. Now it's not happening to me either.

Impressively fast, thanks!
