Python3.13: ModuleNotFoundError: No module named 'xdrlib'

[Bastian-Krause]

python-vxi11 uses xdrlib:

python-vxi11/vxi11/rpc.py

Line 22 in cc4671d

import xdrlib

python-vxi11/vxi11/rpc.py

Line 65 in cc4671d

class Packer(xdrlib.Packer):

python-vxi11/vxi11/rpc.py

Line 100 in cc4671d

class Unpacker(xdrlib.Unpacker):

The xdrlib module documentation in the Python standard library reads:

Deprecated since version 3.11, will be removed in version 3.13: The xdrlib module is deprecated (see PEP 594 for details).

Python 3.13 is expected on 2024-10-07.

Importing the vxi11 now indeed fails with ModuleNotFoundError over the xdrlib. Could this be updated to use e.g. the https://pypi.org/project/xdrlib3/ which is a fork, for Python versions >=3.7? Only change needed would be in the import to change it import xdrlib3 as xdrlib. The second fork that is also available, https://pypi.org/project/py-xdrlib/, (version 4.0.2) can also be used. This is even easier if introduced in the project dependencies as the import statement can then stay the same. But the Python version requirement is set for some reason to be >=3.11. This can give compatibility problems with other dependencies to older packages.

The easiest solution might be to use https://github.com/youknowone/python-deadlib.

After pip install standard-xdrlib you can do:

>>> import xdrlib
<python-input-0>:1: DeprecationWarning: xdrlib was removed in Python 3.13. Please be aware that you are currently NOT using standard 'xdrlib', but instead a separately installed 'standard-xdrlib'.
  import xdrlib

And the version is currently 3.13.0, so version requirement should even be fine as is.
