Proposed change
This is the same change already made in
aiohttp
3.11.10+ that we need for our cache layer as well.https://docs.python.org/3/library/mimetypes.html#mimetypes.guess_type
These should have been changed to
guess_file_type
on Python 3.13 asguess_type
expects a URL andguess_file_type
expects a path. Its a soft deprecation so they still work but that may change in the future.Note that there are quite a few more in the codebase as well, but we may want to wait on those until Python 3.12 support is dropped since they are more rare. The downside to calling
guess_type
is it will parse the file as aURL
which is not cheap.Type of change
