journald: TypeError: signal handler must be signal.SIG_IGN, signal.SIG_DFL, or a callable object

[juju4]

I'm trying to implement a journald option
master...juju4:spython:devel-journald

build ok (tested on Fedora 41/python 3.13.2)
usage nok (TypeError, see readme.md)

$ ./spython

Same with TERM screen-256color and xterm, or with PYTHONUSEREPL=0

Setting "TERM=dumb " makes it work.

If you omit PySys_AddAuditHook(journaldHook, NULL); from your code, does it change anything? If not, please report this at https://github.com/python/cpython, as it's more likely due to your build options and I can't help with those.

If commenting that out fixes the issue, then it probably still needs to be reported over there. This repository is for samples, not for support.

Thanks
Removing the suggested line does not help.
Issue does not happen on Debian12 (python 3.11; with output) or Ubuntu22.04 (python 3.10; no output in journald).
Will open/opened issue upstream.
Would you be interested in a PR with this journald (and journald+network) example?

Sure! Go ahead and set it up like the others, and if you want to give yourself credit then put in a README.md in the directory with the example.

done. Thanks!
