Package conflicts when installing client bindings

[maartenbeeckmans]

When I'm installing client bindings for some custom scripting with packages from the rpm repository, there are package conflics as multiple files are owned by the same repository.

python3-pulpcore-client and python3-pulpcore have conflicts on the same file
The same is happening for python3-pulpcore-client and python3-pulp-rpm-client

Already tried the option --best but that isn't helping.

Using a mirror (updated to upstream) of the pulpcore 3.14 repository
Vm is running EL8

I wonder if this is also a problem in upstream. It's odd to me that they chose the pulpcore.client namespace. It implies the client tools need pulpcore to be installed too, but that's not logical.

[maartenbeeckmans]

Did some further investigation in a python container:

1. when I only install pulpcore-client with pip it creates the following files:

root@88697ba93215:/usr/local/lib/python3.10/site-packages/pulpcore# pwd
/usr/local/lib/python3.10/site-packages/pulpcore
root@88697ba93215:/usr/local/lib/python3.10/site-packages/pulpcore# ls
__init__.py  __pycache__  client

root@88697ba93215:/usr/local/lib/python3.10/site-packages/pulpcore/client# pwd
/usr/local/lib/python3.10/site-packages/pulpcore/client
root@88697ba93215:/usr/local/lib/python3.10/site-packages/pulpcore/client# ls
__init__.py  __pycache__  pulpcore

Client bindings are under the pulpcore folder

2. when I only install pulp-rpm-client with pip it creates the following files

root@e84e84946736:/usr/local/lib/python3.10/site-packages/pulpcore# pwd
/usr/local/lib/python3.10/site-packages/pulpcore
root@e84e84946736:/usr/local/lib/python3.10/site-packages/pulpcore# ls
__init__.py  __pycache__  client

root@e84e84946736:/usr/local/lib/python3.10/site-packages/pulpcore/client# pwd
/usr/local/lib/python3.10/site-packages/pulpcore/client
root@e84e84946736:/usr/local/lib/python3.10/site-packages/pulpcore/client# ls
__init__.py  __pycache__  pulp_rpm

Client bindings are under the pulp_rpm folder

3. when I install both pulpcore-client and pulp-rpm-client with pip it creates the following files

root@0150e93eb1dd:/usr/local/lib/python3.10/site-packages/pulpcore# pwd
/usr/local/lib/python3.10/site-packages/pulpcore
root@0150e93eb1dd:/usr/local/lib/python3.10/site-packages/pulpcore# ls
__init__.py  __pycache__  client

root@0150e93eb1dd:/usr/local/lib/python3.10/site-packages/pulpcore/client# pwd
/usr/local/lib/python3.10/site-packages/pulpcore/client
root@0150e93eb1dd:/usr/local/lib/python3.10/site-packages/pulpcore/client# ls
__init__.py  __pycache__  pulp_rpm  pulpcore

Client bindings are installed under the pulp_rpm and pulpcore folders

For testing I was using the python:bullseye container with python 3.10 installed, but that shouldn't really matter

So when installing it with pip, some files like the __init__.py and __pycache__ folder and subfiles are managed by both pip packages. Pip doesn't really care about it but yum/dnf/rpm does.

No idea how we should proceed with this.

Looks indeed that they are installed in the same namespace.

I think this should be taken up with upstream. I know Python has a mechanism with .pth files but I've never used it and don't know if it's really a solution.
