[Pkg-mailman-hackers] Bug#1082541: mailman3-web: Still with Debian-13-Trixie

[Philipp Matthias Hahn]

Package: mailman3-web
Version: 0+20240312-1
Followup-For: Bug #1082541
X-Debbugs-Cc: 1078661 at bugs.debian.org

Dear fellow Maintainer,

as of today I got 2.8k mails from cron because of failing jobs:
- /var/run/mailman3-web/cron.minutely
- /var/run/mailman3-web/cron.quarter_hourl
- /var/run/mailman3-web/cron.hourly
- /var/run/mailman3-web/cron.daily

This time caused by
  python3-robot-detection: /usr/lib/python3/dist-packages/robot_detection.py

> /usr/lib/python3/dist-packages/robot_detection.py:13: SyntaxWarning: invalid escape sequence '\-'
>   'google\-sitemaps',
> /usr/lib/python3/dist-packages/robot_detection.py:27: SyntaxWarning: invalid escape sequence '\/'
>   '^voyager\/',
> /usr/lib/python3/dist-packages/robot_detection.py:34: SyntaxWarning: invalid escape sequence '\-'
>   'fast\-webcrawler',

>   'ia_archiver\-web\.archive\.org', # Must be before ia_archiver to avoid confusion with alexa
...

I have patched my /etc/cron.d/mailman3-web to have an '2>/dev/null'
after each cron command to silence this for now.

This is sub-optimal as now all errors are lost. Maybe better redirect
those errors to some log file.
Even better would be rate-limiting to one messeage per time-unit.


python3-robot-detection should also be fixed, but as mailman3-web seems
to have a similar problem after each Debian update, do not just hope
that all Python-3 packages will be fixed next time.
Maybe add a `autopkgtest` to check for those warnings automatically?
