`profile` and `cProfile` cannot profile a directory or PEP-441 zip file

Bug report

Python can execute zip files (PEP-441) and directories directly, e.g. python code.zip or python directory, if they're constructed appropriately (such as via zipapp or https://github.com/pantsbuild/pex). These don't work with profile or cProfile modules, e.g. python -m profile code.zip fails with ValueError: source code string cannot contain null bytes and python -m cProfile directory fails with IsADirectoryError: [Errno 21] Is a directory: 'directory'.

For example: https://gist.github.com/huonw/52574abce4057afd99abb5e4a7f82b61 has a simple __main__.py and a zip file that contains it:

import sys
print(f"Hello from {sys.argv[0]}")

There's a script that runs all 9 combinations of zip vs. file vs. directory, and no profiling vs. profile vs cProfile. It can be executed via:

git clone https://gist.github.com/huonw/52574abce4057afd99abb5e4a7f82b61
cd 52574abce4057afd99abb5e4a7f82b61
./script.sh

Output of script.sh:

Archive:  code.zip

IsADirectoryError: [Errno 21] Is a directory: 'directory'

Workarounds:

• for a zip, manually unzip, and then run the __main__.py, e.g. unzip code.zip -d directory && python -m cProfile directory/__main__.py.
• for a directory, run the __main__.py, e.g. python -m cPorfile directory/__main__.py

Your environment

• CPython versions tested on: 3.9.10, 3.10.4, 3.11.0
• Operating system and architecture: python -m platform == macOS-12.5.1-arm64-arm-64bit

Beginne bei den Moduleinstiegspunkten von profile.py und cProfile.py und führe dann den bereitgestellten Reproducer script.sh für die Fälle Datei, ZIP und Verzeichnis aus. Als erledigt gilt die Aufgabe, wenn beide Profiling-Befehle PEP-441-ZIP-Dateien und ausführbare Verzeichnisse ohne den gemeldeten ValueError oder IsADirectoryError verarbeiten.
