Bug report
runpy.run_path will accept a Path object, and run it, but various code inspection tools will be unhappy with it because it is not a string. Should run_path convert its argument to a true string before execution?
Coverage.py is one of those tools; this report is based on coveragepy/coveragepy#1417.
Create debugme.py:
from pathlib import Path
import runpy, sys
runme = Path(__file__).resolve().parent / sys.argv[1]
print(f"Running {runme!r}")
runpy.run_path(runme)Create inspectme.py:
import inspect
print(inspect.stack())
print('here')Run it:
% python3.12 debugme.py inspectme.py

I don't understand why a simpler trace example gets a string for co_filename? Create traceme.py:
import sys
def foo():
print("FOO")
def trace(frame, event, arg):
if "traceme" in str(frame.f_code.co_filename):
print(type(frame.f_code.co_filename))
print(f"{frame.f_code.co_filename=}")
sys.settrace(trace)
foo()
print('here')and run it:
% python debugme.py traceme.py
Running PosixPath('/System/Volumes/Data/root/src/bugs/bug1417/traceme.py')
<class 'str'>
frame.f_code.co_filename='/System/Volumes/Data/root/src/bugs/bug1417/traceme.py'
FOO
