Not working for me

[papb]

I am using pylint 2.9.3, the exit code is still zero.

Workaround:

find .venv/lib -path '*/pylint/constants.py' -exec sed -r -i -e 's@(^MSG_TYPES_STATUS = .*):\s*0,(.*)@\1: 4,\2  # monkey-patched, waiting for pylint#3363@g' {} ';'

The reason that this no longer works is commit pylint-dev/pylint@ab094ae. This changed the default behaviour of pylint so that a run will automatically be marked as succeeding if its score is >= config.fail_under (where as previously it only required score > config.fail_under).

Since informational alerts do not affect the score, runs with (only) them finish with a perfect 10.0 / 10.0 score and so this shortcut is applied and an exit(0) is immediately triggered. You can prevent this shortcut from triggering by also setting the fail_under value to be something larger than 10, for example by adding --fail-under=11 to your usage of pylint.

--fail-on=useless-suppression should also work (if you've got a precise list of interesting Informational code)

I ended up solving my problem by updating pylint and adding the following to my .pylintrc (without need for this package):

evaluation=10.0 - ((float(5 * error + warning + refactor + convention + info) / statement) * 10)
