Backport changed from 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN to 2.5: UNKNOWN, 2.6: REQUIRED, 2.7: REQUIRED, 3.0: REQUIRED I have confirmed that the issue is reproducible on 2.6/2.7 too. ---------------------------------------- Bug #17735: `Hash#transform_keys!` drops non evaluated keys https://bugs.ruby-lang.org/issues/17735#change-91133 * Author: kachick (Kenichi Kamiya) * Status: Closed * Priority: Normal * ruby -v: ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-darwin20] * Backport: 2.5: UNKNOWN, 2.6: REQUIRED, 2.7: REQUIRED, 3.0: REQUIRED ---------------------------------------- ```ruby hash = {a: 1, b: 2, c: 3} hash.transform_values!(){ raise } rescue p hash #=> {:a=>1, :b=>2, :c=>3} ``` ```ruby hash = {a: 1, b: 2, c: 3} hash.transform_keys!(){ raise } rescue p hash #=> {} ``` Is this an intentional behavior? I expected behavior like `transform_values!` in `transform_keys!` (Keeping non evaluated key-value pairs when exiting the block).
