@trichter i rewrote the functionality from xdrlib (didnt commit or push yet).. but I'll first ask over at cpython if we can just copy paste that file, that would be easiest and safest

[megies]

Ah whatever.. @trichter I just pushed my rewrite of what was used. Tests pass but not all code in ah is covered by tests.. whelp. Can't be asked to start a research project about whether we can include that code from cpython codebase or not

I think it is absolutely no problem to copy Python's xdrlib.py and the test file over to ObsPy. We can just include the PSF license in the doc string of the two files. It is GPL compatible and thus also compatible with LGPL.

Like so? We need to handle a merge conflict however.

@megies I think it is ready. Later we can check the wheel for py3.11 win again. Its not working because the wheel for lxml is still missing.
