Warnings when running s3cmd 2.4.0 on Python 3.12 (Linux Mint22.2/Ubuntu)

[rustlegit]

(Note I am not a regular user of Github - this was written by ChatGPT but seems to me to describe the issue, I am in the process of upgrading to Linux Mint 22.2 which now uses a newer version of Python)

Environment

• Linux Mint 22.2 (based on Ubuntu 24.04)
• Python 3.12.7
• s3cmd 2.4.0-2 (installed from Mint/Ubuntu repository)

Observed behavior
Running s3cmd produces multiple warnings:

/usr/local/bin/s3cmd:4: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
import('pkg_resources').run_script('s3cmd==2.4.0', 's3cmd')
/usr/local/lib/python3.12/dist-packages/s3cmd-2.4.0-py3.12.egg/S3/S3Uri.py:122: SyntaxWarning: invalid escape sequence '.'
/usr/local/lib/python3.12/dist-packages/s3cmd-2.4.0-py3.12.egg/S3/S3Uri.py:170: SyntaxWarning: invalid escape sequence '\w'
/usr/local/lib/python3.12/dist-packages/s3cmd-2.4.0-py3.12.egg/S3/FileLists.py:525: SyntaxWarning: invalid escape sequence '*'

Expected behavior
No warnings should be emitted during normal usage.

Notes

• These warnings appear only after upgrading to Python 3.12 (they were not present with Python 3.11).
• The pkg_resources warning comes from the entry point script using pkg_resources.run_script().
• The SyntaxWarnings are due to regex strings written as "\\.", "\\w", "\\*" instead of raw strings (r"\.", etc.).

Suggested fix

• Update regex patterns to use raw strings.
• Replace pkg_resources.run_script() with modern setuptools entry points or direct imports.

Related reports

• Issue Cannot run with python 3.12 on macOS sonoma #1343: "Cannot run with Python 3.12 on macOS Sonoma" (runtime errors, not warnings).
• Homebrew issue #152280: mentions s3cmd packaging problems with Python 3.12.
• No pull requests currently address these warnings.

Impact
Functionality is not broken, but the warnings are noisy and may confuse users.
