Wrong egg-info selected #5070
Description
setuptools version
setuptools-68.2.2
Python version
python3.12
OS
RHEL8
Additional environment information
The problem seems to exists for quite some time. Googling for it, I found this old posting, which describes the same issue: https://stackoverflow.com/questions/62579080/issue-with-loading-entry-point-possibly-connected-to-version-including-dev-tag
Description
I have a script that contains: load_entry_point('CCMS==8.8', 'console_scripts', 'ccms_config')
In /usr/lib/python3.12/site-packages/ there are multiple egg-infos:
CCMS-8.7-py3.12.egg-info
CCMS-8.7.2-py3.12.egg-info
CCMS-8.8-py3.12.egg-info
Actually all but the last are empty left-overs from old RPMs.
On most machines, all works fine, but on some, setuptools tries to use CCMS-8.7.2-py3.12.egg-info and the script fails.
Expected behavior
Since load_entry_point is called with "CCMS==8.8", I would expect setuptools to use CCMS-8.8-py3.12.egg-info on all machines
I don't really understand how all this setup stuff is done in the RPM, but the whole issue wouldn't arise, if the egg-info directory were part of the RPM. Currently only the files are part of the RPM, which is why RPM does not automatically delete the directory during an upgrade.
How to Reproduce
I don't know how to reproduce it.
We install a newer CCMS RPM, and most of the time everything is fine. Sometimes it is not, and when we have the issue, it remains, until we delete the old egg-info.
I guess we should modify our RPMs to delete old egg-infos, but nevertheless. old egg-infos shouldn't break anything like that.
