Overrode Hash#nested_under_indifferent_access in HashWithIndifferentAccess

to return self.

Skip assets options in environments files when --skip-sprockets is used

Add button_tag support to ActionView::Helpers::FormBuilder

This support is near-identical to the existing submit_tag support.

Example:

    <%= form_for @post do |f| %>
      <%= f.button %>
    <% end %>

Use ProcessedAsset#pathname in Sprockets helpers when debugging is on. Closes #3333 #3348 #3361.

This case was not tested and documentation was a bit confusing
on that topic, so it was not obvious if current code
works properly or not.

Is wrong use ProcessedAsset#to_s since it returns the content of the file.

Add test to verify that therubyrhino isn't included when JRuby isn't used

Skip assets groups if --skip-sprockets option is given

    logs for a certain block, change the log level for that block.

*   ActiveSupport::BufferedLogger#open_log is deprecated.  This method should
    not have been public in the first place.

*   ActiveSupport::BufferedLogger's behavior of automatically creating the
    directory for your log file is deprecated.  Please make sure to create the
    directory for your log file before instantiating.

*   ActiveSupport::BufferedLogger#auto_flushing is deprecated.  Either set the
    sync level on the underlying file handle like this:

        f = File.open('foo.log', 'w')
        f.sync = true
        ActiveSupport::BufferedLogger.new f

    Or tune your filesystem.  The FS cache is now what controls flushing.

*   ActiveSupport::BufferedLogger#flush is deprecated.  Set sync on your
    filehandle, or tune your filesystem.

Add the .rdoc extension to the README that Rails generates for a new app

Scope in migrations can be defined by adding suffix in filename,
like: 01_a_migration.blog.rb. Such migration have blog scope.

Scope is automatically added while copying migrations from engine,
so if you want to revert all of the migrations from given engine,
you can just run db:migrate with SCOPE, like:

    rake db:migrate SCOPE=blog

Example:
  ActiveRecord::Migrator.migrate(path) do |migration|
    migration.name =~ /User/
  end

The above example will migrate only migrations with User in
the name
