NoMethodError (undefined method `bytesize' for Rack::Utils:Module):

[diogolmenezes]

Hello, i am usng nginx + unicorn in production env, but when my stand alone server receives a request i get this erro at log/websocket_rails_server.log

NoMethodError (undefined method `bytesize' for Rack::Utils:Module):
vendor/bundle/ruby/2.3.0/gems/websocket-rails-0.7.0/lib/websocket_rails/connection_adapters/http.rb:62:in `encode_chunk'

And in line 62 of http.rb ([https://github.com/websocket-rails/websocket-rails/blob/master/lib/websocket_rails/connection_adapters/http.rb]) we have this code block:

 # From [Rack::Stream](https://github.com/intridea/rack-stream)
      def encode_chunk(c)
        return nil if c.nil?
        # hack to work with Rack::File for now, should not TE chunked
        # things that aren't strings or respond to bytesize
        c = ::File.read(c.path) if c.kind_of?(Rack::File)
        size = Rack::Utils.bytesize(c)
        return nil if size == 0
        c.dup.force_encoding(Encoding::BINARY) if c.respond_to?(:force_encoding)
        [size.to_s(16), TERM, c, TERM].join
      end

I searched at Rack::Utils lib for and the method bytesize does not exists, so a open my vendor/bundle/ruby/2.3.0/gems/websocket-rails-0.7.0/lib/websocket_rails/connection_adapters/http.rb file end changed this:

size = Rack::Utils.bytesize(c)

to this:

size = c.bytesize

and it worked. I supose its a websocket-rails bug, could u help ?

I'm seeing something similar.

I got the same:
NoMethodError: undefined method bytesize' for Rack::Utils:Module vendor/bundle/ruby/2.4.0/gems/websocket-rails-0.7.0/lib/websocket_rails/connection_adapters/http.rb:62:in encode_chunk'

I worked around it by adding rack_utils_patch.rb to config/initializers/ with the following content:

module Rack
module Utils
# Return the bytesize of String; uses String#size under Ruby 1.8 and
# String#bytesize under 1.9.
if ''.respond_to?(:bytesize)
def bytesize(string)
string.bytesize
end
else
def bytesize(string)
string.size
end
end
module_function :bytesize

end

end
