It appears this commit:

https://github.com/ruby/ruby/commit/43284b6bf8324a762808537d5cd2c0774b662a84

Breaks our test suite, with this error from the redis namespace gem. Here is a trackeback from our Rails app:

Namespace is not a module
/usr/lib/ruby/gems/1.9.1/bundler/gems/redis-store-b70b9326d083/lib/redis/store/namespace.rb:3:in <class:Store>' /usr/lib/ruby/gems/1.9.1/bundler/gems/redis-store-b70b9326d083/lib/redis/store/namespace.rb:2:in class:Redis'

Line 6 in redis-store.rb is:

require "redis/store/namespace"

And then the top of namespace looks like this:
class Redis
class Store < self
module Namespace

Not sure if this is an intentional change or not, but a heads up its breaks the gem.

Thanks - Charlie

Note the ruby -v version attached to the ticket isn't the one I used for testing.

• ruby -v changed from ruby 1.9.4dev (2011-09-01 trunk 33153) [x86_64-linux] to r33157

Simplified code doesn't reproduce it.

class Redis; class Store < self; module Namespace; end; end; end

Is "Namespace" constant defined elsewhere at that point?

[cfis (Charlie Savage)]

Ok, can reproduce like this:

require 'rubygems'
require 'redis-namespace'
require 'redis-store'

Which when you go look at the gems source ends up like this:

# from redis-namespace (lib/redis/namespace.rb)
class Redis
  class Namespace
  end
end

# from redis-store (lib/redis/store/namespace.rb)
class Redis
  class Store < self
    module Namespace
    end
  end
end

I can see why Ruby is complaining, but this code works on 1.8.7 and did work on 1.9.3 until commit 33157.
