Subject: [ruby-core:40318] [ruby-trunk - Feature #5481] Gemifying Ruby standard library


Issue #5481 has been updated by Hiroshi Nakamura.


=begin
== Background

There was an awesome keynote by Aaron at RubyKaigi2011.

 * RubyKaigi 2011 keynote by Aaron Patterson (tenderlove) / AT&T Interactive: ((<URL:http://vimeo.com/26507951>))
 * Most relevant parts for this topic
   * 14'27" -- 25'55": Ruby's release cycle and gem inconsistencies
   * 24'05" -- 27'25": Converting stdlib into gems and release them along with the ruby tarball ("That's one thing I'd like to see changed")

At the next session, Matz and Japanese ruby-core committers discussed the next ruby release. Matz said 'there will be no 1.9.4 because it becomes 2.0'. (Note: See the discussion at ((<URL:https://redmine.ruby-lang.org/issues/5056>)).)

Any detailed changes for 2.0 were not known but I (NaHi) thought that gemifying stdlib should happen before the changes because it would include incompatible behaviors.  The work for gemifying would be postponed after 2.0 release (we must be busy for stabilizing 2.0 release.) I was thinking that gemifying stdlib for faster iteration (shorter release cycle) which had been explained in Aaron's keynote was a must and I wanted to see that happen soon. I talked to Aaron(tenderlove) and Eric(drbrain, a maintainer of RubyGems) first about how we could make it happen and to make this proposal.

I also asked Matz about it.

Then I got the reponse 'Talk to Yuki Sonoda(yugui) and Aaron. I say yes'.

 * ((<URL:https://twitter.com/#!/yukihiro_matz/status/92400266493702144>))

So I talked with many ruby committers including Yuki and Aaron at RubyKaigi2011. Lots of discussion about the benefits and what must not happen. Not a unanimous accord, but almost all committers there agreed/understood what we're planning to do by gemifying stdlib.

Now, at the time 1.9.3 is being released, I want to start the work.

Feature #5481: Gemifying Ruby standard library
http://redmine.ruby-lang.org/issues/5481

Author: Hiroshi Nakamura
Status: Open
Priority: Normal
Assignee: 
Category: lib
Target version: 2.0


=begin

Up-to-date summary of this proposal is at ((<URL:https://redmine.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.
