Plans for packaging numpy 2.x
Hi, With numpy 2.0 ostensibly releasing soon [1] and breaking backward compatibility with numpy 1.2X [2], I wonder what the plan for numpy packages will be for openSUSE. Will we maintain two different series of numpy as, for instance, `python-numpy` and `python-numpy2`? This will perhaps be the least breaking path to take for packages dependent on `numpy` — which will probably take a while to catch up — but I understand if the additional maintenance efforts this will require compel otherwise. Also, as someone who maintains a few packages in d:l:p:numeric, I would be happy to help out if needed (maintaining the 1.x branch or any other way). Thanks for the great work you folks do maintaining the seemingly infinite number of python modules as RPM packages. Cheers, [1] https://github.com/numpy/numpy/releases/tag/v2.0.0rc1 [2] https://numpy.org/devdocs/dev/depending_on_numpy.html#numpy-2-abi-handling -- Atri

I would go for keeping python-numpy as the latest version (in this case, 2.0) and create a new package called python-numpy_1. Any package that depends on old numpy can just add the version limit to the spec file like: Requires: python-numpy < 2 And we can keep the old package around for some time, for packages that depends on it or even if there are people using version 1 directly, until upstream drop maintenance support completely. We're doing this for python-urllib3 with python-urllib3_1 [1], so it's a similar pattern.

..which would entail manual fixes for a rather large number of specfiles. What would be the benefit, if I may ask, as opposed to using `python-numpy2` as I suggested above? Thanks for your response. -- Atri

The benefit is that we will keep the upstream name for the package and in the future we just need to drop python-numpy_1. If we do it the other way, at some point we will need to rename the package or we will keep the package name mismatch forever. I mean, if upstream doesn't change the name to numpy2, all the projects that depends on it should also update their dependencies to pin the version when it's released. I would like to keep the package name coherent with the upstream name provided in pypi.org -- Daniel García Moreno Python Packager

+1. Many packages do already pin to numpy < 2. The proposed scheme mirrors the upstream logic and avoids confusion.

FYI I am currently experimenting with numpy 2.0.0rc1 in https://build.opensuse.org/project/show/home:bnavigator:numpy. I have prepared a python-numpy1 package in there, too. There is quite a large number of packages from d:l:p:numeric which fail to build or test when allowing numpy 2. Also, we have the shortcoming of obs to not properly resolve a pin to numpy < 2 in the dependency chain. (See the pandas test flavors for instance, they don't like the numba pinning). - Ben

That's super helpful, big thanks.

On a related note, would it be useful to add Provides: python-numpy1 to the current python-numpy package in Factory, so we could already starting switching the Reqs and BReqs to python-numpy1 (instead of `python-numpy < 2`) for pkgs that will not build with numpy >= 2 right away? Cheers, -- Atri

The list got a bit smaller, with scipy 1.13 becoming compatible.

I'd rather not have the custom name in any Requires or BuildRequires tag. Let's encourage packagers to pin to versions instead of non-standard rpm package names.
