From: usa@... Date: 2016-02-03T10:56:20+00:00 Subject: [ruby-core:73681] [Ruby trunk Bug#11740] ObjectSpace.each_object exposes internal metaclasses Issue #11740 has been updated by Usaku NAKAMURA. Backport changed from 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN to 2.0.0: DONTNEED, 2.1: DONTNEED, 2.2: DONTNEED ---------------------------------------- Bug #11740: ObjectSpace.each_object exposes internal metaclasses https://bugs.ruby-lang.org/issues/11740#change-56876 * Author: Benoit Daloze * Status: Closed * Priority: Normal * Assignee: Koichi Sasada * ruby -v: ruby 2.3.0dev (2015-11-19 trunk 52672) [x86_64-linux] * Backport: 2.0.0: DONTNEED, 2.1: DONTNEED, 2.2: DONTNEED ---------------------------------------- ObjectSpace.each_object exposes internal metaclasses and this might result in assumptions being violated since the metaclass structure is not well preserved. See the attached script for an example. The #bla method should always be defined on the metaclass of "klass". See https://bugs.ruby-lang.org/issues/11360#note-2 as well in which I warned against this problem ;) ---Files-------------------------------- objspace_expose_intern_meta.rb (413 Bytes) -- https://bugs.ruby-lang.org/ Unsubscribe:
