[kloczek]

Actually more important is that ipython_genutils is still using nose which is for python 2.x and is already outdated and unmaintained.

I think it will likely be easier to remove usage of ipython_genutils upstream than to fix this repo.
If you have specific packages that needs dependency on ipython_genutils to be remove faster than other, you can list them here, and we'll do what we can.

[kloczek]

Just checked what is using ipython-genutils

[tkloczko@barrel SPECS]$ grep 'python3dist(ipython-genutils)' *
python-ipyparallel.spec:BuildRequires: python3dist(ipython-genutils)
python-notebook.spec:BuildRequires: python3dist(ipython-genutils)
python-traitlets.spec:BuildRequires: python3dist(ipython-genutils)

Simple what I'm tryig to archive is have set of packages without nose run-time or build-time dependencies.

[Carreau]

I'll open issues on relevant repositories, we can likely make a new minor release of all the above projects that do not requires this package.

I know there are other packages that require ipython_genutils, but we can make those a priority.

[Carreau]

master of ipyparallel should not require ipython_genutils anymore, I believe this will be part of the next major version (7.0.0) that I guess might be released soon.

[kloczek]

master of ipyparallel should not require ipython_genutils anymore, I believe this will be part of the next major version (7.0.0) that I guess might be released soon.

If may I suggest move away from nose as well because of https://nose.readthedocs.io/en/latest/
https://github.com/schollii/nose2pytest/ may be useful on that.

[Carreau]

+1 thanks, I've been using vim macros, but that is helpful. We have some custom plugins that might need manual work.

Fedora packages with ipython_genutils deps:

python3-ipywidgets-0:7.6.4-2.fc36.noarch
python3-nbformat-0:5.0.8-6.fc36.noarch
python3-notebook-0:6.4.8-1.fc36.noarch
python3-qtconsole-0:5.2.2-2.fc36.noarch

[kloczek]

[tkloczko@ss-desktop SPECS.fedora]$ grep nose python-ipython_genutils.spec
# Don't use deprecated unittest aliases trough nose, they are removed in Python 3.11
BuildRequires: python%{python3_pkgversion}-nose
nosetests-%{python3_version} -v
- Use nosetests

As you see Fedora package uses nose.

[Carreau]

IPython 8 which has been published two weeks ago does no rely on nose or ipython_genutils anymore.
I would though wait for IPython 8.1.0 there are a couple of things to fix.

[Carreau]

You may still want to try to package 8.0 as a number of things have changed in setup.py (we are trying to get rid of it), and it also now requires stack_data. 8.0 also has black as a dependency but that will be most likely removed in 8.1.

[Carreau]

spyder-ide/qtconsole#586 should remove the last usage of it from qtconsole, so AFAICT once the above is merged and released, nothing should use ipython_genuils.

Let me know if that is not the case.
