pipes no longer supported in Python 3.13

[lucbouge]

Dear @xolox Peter,

I tried to install you excellent software rotate-backups with Python 3.13, and it unfortunately failed. As far as I can understand,
it is based in executor, which imports module pipes, which is deprecated in Python 3.13

from executor/__init__.py

# Standard library modules.
import errno
import logging
import os
import pipes
import pprint
import shlex
import signal
import subprocess
import sys
import tempfile

from https://docs.python.org/3/library/pipes.html#module-pipes

This module is no longer part of the Python standard library. It was removed in Python 3.13 after being deprecated in Python 3.11. The removal was decided in PEP 594.

Applications should use the subprocess module instead.

The last version of Python that provided the pipes module was Python 3.12.

Hopefully, I could force installation with Python 3.12.

Do you intend to update module executor with subprocess?

Best regards,

Luc (from Britanny, France)

The fix is trivial actually and doesn't require switching to process, see:

Thanks a lot for your instant answer and the tip. It worked like a charm.

Please reopen this issue, this is not actually fixed and other people may need to see this.

Dear @Beuc,

I came to notice project https://pypi.org/project/backup_warden/, which explicitly acknowledges @xolox's rotate-backups as its source of inspiration. At a first glance, it looks to be pretty compatible. The last version has been committed on Nov 28 2024.

Have you heard of it?

Hi. Yes but from my notes the directory structure was more rigid and it lacked --removal-command.
