rails3 breaks base64 stdlib?

#3961

Rails 3.0.0.beta seems to break the base64 in the stdlib. See below.

I'm aware of ActiveSupport::Base64.encode64 in the meantime.

    $ irb
    ruby-1.9.1-p378 > require 'base64'
    => true 
    ruby-1.9.1-p378 > Base64.b64encode('blah')
    YmxhaA==
    => "YmxhaA==\n" 


    $ rails console
    Loading development environment (Rails 3.0.0.beta)
    ruby-1.9.1-p378 > require 'base64'
    => [] 
    ruby-1.9.1-p378 > Base64.b64encode('blah')
    NoMethodError: undefined method `b64encode' for Base64:Module
            from (irb):1
            from /Users/daniel/.rvm/gems/ruby-1.9.1-p378/gems/railties-3.0.0.beta/lib/rails/commands/console.rb:47:in `start'
            from /Users/daniel/.rvm/gems/ruby-1.9.1-p378/gems/railties-3.0.0.beta/lib/rails/commands/console.rb:8:in `start'

            from /Users/daniel/km/survey/srails/script/rails:10:in `<main>'

+1 I can reproduce it in ruby 1.9.1 but it worked in ruby 1.8.7

I noticed the same thing, but it looks like this is a change between Ruby 1.8 and Ruby 1.9 and not a problem with Rails. According to the Ruby 1.9 Rdoc, that method does not exist, while the Ruby 1.8.6 Rdoc does have b64encode.

In addition, a plain irb session in Ruby 1.9.1-p378 behaves identically to what you experienced in the rails console. Rails is mentioned in the stack trace because you used the rails console instead of irb.
```
$ irb
ruby-1.9.1-p378 > require 'base64'
 => true 
ruby-1.9.1-p378 > Base64.b64encode('blah')
NoMethodError: undefined method `b64encode' for Base64:Module
    from (irb):2
    from /Users/isomorphix/.rvm/rubies/ruby-1.9.1-p378/bin/irb:17:in `<main>'
ruby-1.9.1-p378 >
```

Jose:

please add some explanation why it was marked invalid?

It's pretty clear I'm not able to use it, regardless of what isomorphix said, and I hope you didn't close it only based on what he said.

i.e. I can use it just fine in irb, but it does not behave as expected in rails.
