i3639 Fix Python 3.12 tests

[agriyakhetarpal]

Description

Closes #3639. This is a minimal and temporary fix for now, I will chase this down soon and try to fix the issue for the pybtex repository upstream when I get time.

Type of change

Please add a line in the relevant section of CHANGELOG.md to document the change (include PR #) - note reverse order of PR #s. If necessary, also add to the list of breaking changes.

• New feature (non-breaking change which adds functionality)
• Optimization (back-end change that speeds up the code)
• Bug fix (non-breaking change which fixes an issue)

Key checklist:

• No style issues: $ pre-commit run (or $ nox -s pre-commit) (see CONTRIBUTING.md for how to set this up to run automatically when committing locally, in just two lines of code)
• All tests pass: $ python run-tests.py --all (or $ nox -s tests)
• The documentation builds: $ python run-tests.py --doctest (or $ nox -s doctests)

You can run integration tests, unit tests, and doctests together at once, using $ python run-tests.py --quick (or $ nox -s quick).

Further checks:

• Code is commented, particularly in hard-to-understand areas
• Tests added that prove fix is effective or that feature works

Thanks, looks good, @agriyakhetarpal! IIRC pybtex is not maintained anymore and it would be greatly appreciated if you fix this issue upstream.

If pybibtex is dead, should we switch to something else instead?

I found this active project for parsing bibtex: https://github.com/sciunto-org/python-bibtexparser

[agriyakhetarpal]

I was looking at some projects too yesterday and this one looks good to me as well. I will convert your comment to an issue, @kratman – an upstream PR for pybtex is on my radar for the start of next year as soon as my exams end, which should suffice our requirements, but switching to a new dependency altogether would be great.

Thanks @agriyakhetarpal, looks good.
+1 for @kratman's suggestion as that project looks actively maintained, though it'll be also appreciated to look into the issue upstream. Maybe we can decide upon the complexity of the issue upstream.
