Monkeypatch for rubyforge gem’s “error occurred while evaluating nil.tmp_dh_callback=”

By hakunin on December 8, 2008

This is the way to get rid of ‘nil.tmp_dh_callback=’ bug by using Rails plugin. Whenever they fix this in rubyforge gem – simply remove the plugin directory from vendor/plugins.

cd rails_app/vendor/plugins
mkdir rubyforge_patch
cd rubyforge_patch
mate init.rb

Paste this into init.rb

require 'net/http'

class Net::HTTP
  def use_ssl= flag
    self.old_use_ssl = flag
    @ssl_context.tmp_dh_callback = proc {} if flag
  end
end if Net::HTTP.public_instance_methods.include? "old_use_ssl="

That’s it. You’re good to go. No more nil.tmp_dh_callback error.

    Thanks! This saved me some headaches tonight.

    Minor nits on the instructions: 1) remove the ‘s’ in vendors and 2) add a “cd rubyforge_patch” cmd after the mkdir command.

    Thanks again! Very helpful.

    Great patch. Thanks.

    An alternate place to put the code would be in config/initializer/rubyforge_patch.rb.
