Missing (?) deps for python3-jupyter_events

[tornaria]

Is this a new report?

Yes

System Info

x86_64

Package(s) Affected

python3-jupyter_events-0.10.0_2, python3-jsonschema-4.23.0_3

Does a report exist for this bug with the project's home (upstream) and/or another distro?

No response

Expected behaviour

No missing deps

Actual behaviour

The python package jupyter-events depends on jsonschema[format-nongpl]>=4.18.0, but we only provide jsonschema. In order to provide jsonschema[format-nongpl] we are missing fqn, isoduration, uri-template, webcolors.

Steps to reproduce

$ python -c 'from build._util import check_dependency;print(*check_dependency("jupyter-events"),sep="\n")'
('jupyter-events', 'jsonschema[format-nongpl]>=4.18.0', 'fqdn; extra == "format-nongpl"')
('jupyter-events', 'jsonschema[format-nongpl]>=4.18.0', 'isoduration; extra == "format-nongpl"')
('jupyter-events', 'jsonschema[format-nongpl]>=4.18.0', 'jsonpointer>1.13; extra == "format-nongpl"')
('jupyter-events', 'jsonschema[format-nongpl]>=4.18.0', 'uri-template; extra == "format-nongpl"')
('jupyter-events', 'jsonschema[format-nongpl]>=4.18.0', 'webcolors>=24.6.0; extra == "format-nongpl"')

Note: installing python3-jsonpointer fixes that one, but the other four are not packaged.

I see two ways out:

• package the four missing dependencies and add those five dependencies to python3-jupyter_events.
• patch python3-jupyter_events to depend on jsonschema instead of jsonschema[format-nongpl].

This is relevant when building a package that (directly or indirectly) requires jupyter_events at build time (this is forcing us sometimes to patch out dependencies or use --skip-dependency-check, which are non-optimal workarounds).

Related issue: how to catch this type of missing dependencies. The way the pre-hook pre-pkg/06-verify-python-deps.sh checks dependencies is not taking this "extra" argument to dependencies. Ideally, it would complain when packaging jupyter_events that its dependencies are missing, but this doesn't seem easy.

Maybe one option is to install the wheel into a venv (as we do for testing) and use build._util.check_dependency() as above.

Any thoughts about this @classabbyamp ?

they're dependencies, they should be added
