Description Mike 2012-03-30 14:28:32 EDT
Description of problem:

The rubygems package seems to conflict with the version of ruby that is provided in RHEL6.

In /usr/lib/ruby/site_ruby/1.8/rubygems/source_index.rb, "File.read file_name, :encoding => 'UTF-8'" is used in the load_specification() method, but IO.read() in Ruby 1.8.7 does not support the passing of the :encoding hash.

Here is the code snippet:

    def load_specification(file_name)
      return nil unless file_name and File.exist? file_name

      spec_code = if defined? Encoding then
                    File.read file_name, :encoding => 'UTF-8'
                    File.read file_name

And the reproducer:
[mkrysiak@unixdeva16 tmp]$ touch x.rb
[mkrysiak@unixdeva16 tmp]$ irb
irb(main):001:0> File.read 'x.rb', :encoding => 'UTF-8'
TypeError: can't convert Hash into Integer
        from (irb):1:in `read'
        from (irb):1
        from :0

It looks like this feature was added in Ruby 1.9.

Hi Mike,

Could you please be more specific? Under what circumstances it bites you? The Encoding class is not defined by default in Ruby 1.8.7, so it should use the "else" branch and works just fine IMO.
Comment 3 RHEL Product and Program Management 2012-09-07 01:25:25 EDT
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.
