Status changed from Open to Closed I'm not sure if this behavior change between Ruby 2.3 and 2.4 was originally expected. However, I don't see why we would want to revert to the previous, and the current behavior doesn't seem to be a bug. Please submit a feature request if you would like to return to the Ruby <2.4 behavior. ---------------------------------------- Bug #14732: CGI.unescape returns different instance between Ruby 2.3 and 2.4 https://bugs.ruby-lang.org/issues/14732#change-85927 * Author: jnchito (Junichi Ito) * Status: Closed * Priority: Normal * ruby -v: 2.4.4 * Backport: 2.3: REQUIRED, 2.4: REQUIRED, 2.5: REQUIRED ---------------------------------------- In Ruby 2.3, CGI.unescape always returns String object: ~~~ ruby $ ruby -v -rcgi/util -e 'class S < String; end; puts CGI.unescape(S.new("a")).class' ruby 2.3.6p384 (2017-12-14 revision 61254) [x86_64-darwin17] String ~~~ But in Ruby 2.4, it might return non-String object when the argument value is not a String instance: ~~~ ruby $ ruby -v -rcgi/util -e 'class S < String; end; puts CGI.unescape(S.new("a")).class' ruby 2.4.4p296 (2018-03-28 revision 63013) [x86_64-darwin17] S ~~~ This change triggered the following issue: https://github.com/rest-client/rest-client/issues/662 Is this change intentional? -- https://bugs.ruby-lang.org/ Unsubscribe:
