I was getting this intermittent error running my Datasette test suite:
OSError: [Errno 24] Too many open files
To figure out what was going on, I used the
psutil package and its
Here's the documentation for psutil.Process.open_files.
pip install psutil in my virtual environment.
Then I ran
pytest --pdb to drop into a Python debugger when a test failed.
In the debugger I ran this:
import psutil for f in psutil.Process().open_files(): print(f)
This showed the current list of open files for that process, which gave me some clues to help me start resolving the problem.
