Issue #5481 has been updated by headius (Charles Nutter).


FWIW, here's how we're handling the gemification of OpenSSL...

Background: Previously, JRuby's 'openssl' support was always distributed as a gem, since we did not want to ship crypto (bouncycastle). Starting with JRuby 1.7, however, we ship 'openssl' in the standard JRuby distribution. We still want to support users on 1.6.x and want to be able to update 'openssl' independent of JRuby, so for Jruby 1.7.1 we will support using the gem if the gem is installed.

The file within JRuby is here: https://github.com/jruby/jruby/blob/master/lib/ruby/1.9/openssl.rb

This file attempts to load a file that's only in the gem, and the gem then adds its own dirs to LOAD_PATH so future requires will use the gem's versions of things instead of those built into JRuby.

This approach may advise a similar solution in MRI. At the very least, I'm interested in this bug so we use the same mechanism for loading the gem version of a stdlib instead of the shipped version.

I am disappointed this won't happen for 2.0.0.

Up-to-date summary of this proposal is at ((<URL:https://bugs.ruby-lang.org/projects/ruby/wiki/StdlibGem>))

== Motivation

 * ruby's release cycle is slow for some standard libraries;
   * ex. security fix for WEBrick, xmlrpc and Zlib.
   * ex. API iteration for net/http, OpenSSL, json, psych, RDoc, minitest and rake.
 * There's already the feature called 'default gems' in ruby and some stdlibs are already using it:
   * rake, rdoc, minitest, json, io-console, bigdecimal
   * And some gems are already doing out-of-band releases.
 * When releasing we should give independence equally to all stdlibs, but in a consistent and controllable way.

== Proposal

 * Allow out-of-band stdlib releases.
   * We are not proposing changes to ruby's release management, the release manager would decide when they release ruby and stdlib.
 * Allow more stdlibs to be installed as a 'default gem'
 * Register these gems on RubyGems.org
   * Introduce a new mechanism: controlling supported ruby version so that we can avoid installing unexpected version of stdlib gems.
     For example, a WEBrick gem for ruby 2.0.1 (released from ruby_2_0_1 branch) should not be installed for ruby 2.0.0 (released from ruby_2_0_0 branch) unless we know it works for both 2.0.0 and 2.0.1.

Note:

 * Moving stdlibs repository location is not a target of this proposal. The implementation details of stdlib gems should hide this from ruby committers.
 * ruby_1_9_3 is not a target of this proposal. The change should be introduced from 2.0.0 release.


...Some more details of the proposal and discussion topics are going to follow as comments.
