DeprecationWarning: the imp module is deprecated in favour of importlib

[honzajavorek]

extruct uses rdflib==4.2.2, which causes this warning:

/.../python3.8/site-packages/rdflib/plugins/parsers/pyRdfa/utils.py:19
  /.../python3.8/site-packages/rdflib/plugins/parsers/pyRdfa/utils.py:19: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
    import os, os.path, sys, imp, datetime

Not sure if this has been fixed in rdflib==5, I didn't find anything mentioning importlib in the issues or PRs there. Related: RDFLib/rdflib#1196

Thanks for the heads up, right now we're stuck on 4.2.2, #135 is about fixing this - I hope you don't mind closing this as a duplicate.

OK, thanks! No problem, I'll subscribe to the other issue 👍

This issue may be still be valid - I've upgraded to rdflib v7.0.0 for a project that uses extruct locally, and I continue to see runtime warning messages about the imp import from pyRdfa3.

The imp module has been removed from the Python 3.12-dev branch, so this may become more important soon.

In terms of fixes: it looks like the relevant import was removed from pyRdfa3 back in Y2020, although that change is not-yet-released. There's an issue to request an updated release at RDFLib/pyrdfa3#37 (note: commenting is disabled because the repository is archived).

thanks for reporting, I didn't manage to check this yet but let me re-open for visibility

This should be confirmed by someone else too, but from my experience this did block an upgrade of a project to Python3.12 (the code began failing when extruct imported pyrdfa3 which in turn tried to import imp that no longer exists in py312).

I can confirm the same thing is happening to me on 3.12:

Python 3.12.0 (main, Oct  2 2023, 00:00:00) [GCC 13.2.1 20230918 (Red Hat 13.2.1-3)] on linux

pyRdfa3 3.6.2 is released on PyPI and includes the commit that removed the imp import.
Also, it looks like development has been moved to https://github.com/prrvchr/pyrdfa3

[jayaddison]

Thanks @MmAaXx500 for the heads-up - I can confirm that with pyrdfa3 v3.6.2 in use, upgrading an extruct-dependent container to Py3.12 has been unblocked here.
