Issue #20573 has been updated by k0kubun (Takashi Kokubun). Backport changed from 3.1: WONTFIX, 3.2: REQUIRED, 3.3: REQUIRED to 3.1: WONTFIX, 3.2: REQUIRED, 3.3: DONE ruby_3_3 commit:a3eb5e5c70eaee12964cdd807b8f19950003141f. ---------------------------------------- Bug #20573: Warning.warn shouldn't be called for disabled warnings https://bugs.ruby-lang.org/issues/20573#change-109027 * Author: tenderlovemaking (Aaron Patterson) * Status: Closed * Backport: 3.1: WONTFIX, 3.2: REQUIRED, 3.3: DONE ---------------------------------------- Currently `Warning.warn` will be called for all warnings, even if that particular category is disabled. For example ```ruby module Warning def warn(message, category:) p message => category end end def get_var $= end p Warning[:deprecated] get_var ``` I think that internally we should _not_ call `Warning.warn` unless the category is enabled. I've sent a PR here: https://github.com/ruby/ruby/pull/10960 -- https://bugs.ruby-lang.org/
