What version of Python were you testing this with?

Depending on your version of Python, the __file__ attribute may be an absolute path or a relative path.

$ cat 5038.py
print(__file__)

$ docker run --network host -it --rm -v $(pwd)/5038.py:/tmp/5038.py python:3.8-slim /bin/bash -c "cd /tmp; python3 5038.py"
5038.py

$ docker run --network host -it --rm -v $(pwd)/5038.py:/tmp/5038.py python:3.9-slim /bin/bash -c "cd /tmp; python3 5038.py"
/tmp/5038.py

$ docker run --network host -it --rm -v $(pwd)/5038.py:/tmp/5038.py python:3.10-slim /bin/bash -c "cd /tmp; python3 5038.py"
/tmp/5038.py

$ docker run --network host -it --rm -v $(pwd)/5038.py:/tmp/5038.py python:3.11-slim /bin/bash -c "cd /tmp; python3 5038.py"
/tmp/5038.py

The behavior changed in Python 3.9 as documented here.

$ rustpython --version
RustPython 0.3.0

$ cp 5038.py /tmp/5038.py
$ cd /tmp
$ rustpython 5038.py
5038.py

It appears that the current RustPython version matches the Python 3.8 behavior.

A possible solution is to modify run_script to call run_code_string with an absolute path.

$ rustpython 5038.py
/tmp/5038.py

This would also cause the traceback to contain the absolute path.

Before patch:

$ pwd
/tmp
$ cat 5038-traceback.py
raise Exception("5038")

$ rustpython 5038-traceback.py
Traceback (most recent call last):
  File "5038-traceback.py", line 1, in <module>
    raise Exception("5038")
Exception: 5038

After patch:

$ rustpython 5038-traceback.py
Traceback (most recent call last):
  File "/tmp/5038-traceback.py", line 1, in <module>
    raise Exception("5038")
Exception: 5038

$ python3 --version
Python 3.10.12
$ python3 5038-traceback.py
Traceback (most recent call last):
  File "/tmp/5038-traceback.py", line 1, in <module>
    raise Exception("5038")
Exception: 5038

I'm sure this solution will require more thought and testings.
