[`flake8-blind-except`] Allow more logging methods (`BLE001`) #22057

lubaskinc0de · 2025-12-18T18:40:38Z

Summary

Fix issue #21889 by checking that the logging method is one of the debug, info, warning, error, exception, critical, log methods that support exc_info passing. Also fixed the behavior in which exc_info was considered passed only when it was equal to the literal True, now the Truthiness of the expression is checked (we will leave additional checks to type checkers)

Test Plan

Additional snapshot tests have been added for all logging functions, as well as tests in which an exception object is passed as exc_info

…mpatible logging method

…ogging.log

Thank you! This looks great overall. I Just had one suggestion about trimming down the number of test cases and one to share some code for the Truthiness checks.

I also think we should make this a preview (link is to an example preview function) change since the ecosystem check is showing a number of changes, including some now-unused noqa comments.
