PyLint's useless-suppression is not producing consistent behaviour with `mock.patch.multiple_targets` about pylint HOT 3 CLOSED

By sometime do you mean in the same environment when calling pylint multiple time ? Or are you using multiple interpreters or multiple environments (differing dependencies, OS, etc) ? Also you could upgrade pylint to 3.0.0a7 to see if the problem still exists :)

@Pierre-Sassoulas The exact same environment but with different command executions (where the command is poetry run pylint my_package tests docs scripts --enable=useless-suppression) - nothing else changes, just different executions of the same command can lead to different outputs (warning and no warning). I can't still upgrade pylint to the latest version because it's incompatible with Python 3.7, which my packages still supports (although we'll soon remove that support). This behaviour is really strange. This probably happening, I would guess, because something is not deterministic. Maybe the way the AST is parsed or the order of the execution of pylint on the different files.

So if I understand you well you launch once with --enable=useless-suppression and the other without ? The code you gave is not parseable (a.py:7:38: E0001: Parsing failed: 'unterminated string literal (detected at line 7) (<unknown>, line 7)' (syntax-error)) so I parsed the following using both option:

from pathlib import Path
from unittest import mock

MODULE_PATH = Path(__file__)

def whatever():
    mocks = mock.patch.multiple_targets(  # pylint: disable=no-member
        [
            mock.patch(MODULE_PATH + '.func1'),
            mock.patch(MODULE_PATH + '.func2'),
        ]
    )

I don't have any issues on main / python 3.11 with this snippet. We did change a lot of things since 2.14, and some for useless-suppression (maybe #7887 in 2.15, but there might be others), so it's probable it was fixed on main and sadly we don't support python 3.7 anymore. Please reopen an issue if you have a reproducer for more recent version of pylint.
