From: "usa (Usaku NAKAMURA)" Date: 2013-02-22T15:07:38+09:00 Subject: [ruby-core:52684] [Backport93 - Backport #7869] Revert JSON version bump, since it posibly breaks Ruby backward compatibility Issue #7869 has been updated by usa (Usaku NAKAMURA). I've read the discussion from [ruby-core:52254], and I may understand your opinion. But my conclusion is: You should do "bundle install" after updating ruby, because bundler says so. I cannot understand the situation where you can update ruby but cannot perform bundle install (or update). Therefore, I continue the principle of "changing the version of bundled gem, if it is updated." But this subject is still open. Please show your opinions on this ticket, guys and dolls. ---------------------------------------- Backport #7869: Revert JSON version bump, since it posibly breaks Ruby backward compatibility https://bugs.ruby-lang.org/issues/7869#change-36776 Author: vo.x (Vit Ondruch) Status: Open Priority: Normal Assignee: Category: Target version: Although reverting version bump means that Ruby's JSON will differs from RubyGems version of JSON, it prevents possible compatibility issues for every project, which might use Bundler to specify its dependencies. Although for regular user, this incompatibility might be fixed by simple 'bundle update' command, it is not doable for Linux distributions, which provides packaged Ruby, including JSON gem, but are not responsible for every Ruby project on the system. See ruby-core:52254 for more discussion. Thank you. -- http://bugs.ruby-lang.org/
