Bug Description

Attempting to use Passenger with Python 3.12 leads to an error "ModuleNotFoundError: No module named 'imp'" and the application fails to run. This is due to the wsgi-loader.py script distributed with Passenger using the imp module which has been deprecated since Python 3.4 and was finally removed in Python 3.12.

This was a known bug in passenger and has been fixed in Passenger 6.0.19:

Encountered this on focal, but looks like noble is also affected.

py312-uses-importlib.patch Edit (1.5 KiB, text/plain)

Attached patch that could be used to fix focal (which uses a passenger 5.0.30, which is no longer maintained upstream).

Impact:

Fixes the fatal error with Passenger / Python 3.12 but preserves existing behavior with <=3.11 (which is to just throw a warning). Compatible w/ Python 2.7 also.

Haven't tested full package yet.
