[RCBC-95] Server's helpful error about map.js errors gets replaced by a generic http 400 happened while uploading design document

Fri, 8 Feb 2013 18:15:14 -0600

Repro:

Create a new model, use the genrator to create a view
add the view line to the model
start the app (rails console)

The default map.js with all the comments in and examples will cause the error already.

Now after a bit of tinkering .. I just added an else to the if block_given? in there .. to reveal the error ..
        if block_given?
          if res.success? && val['error']
            res.error = Error::View.new("save_design_doc", val['error'])
          end
          yield(res)
        else
          unless res.success?
            if val['error'] && val['reason']
              raise Couchbase::Error::View.new(val['error'], val['reason'])
            end
          end
        end

And that returned a much more civil error:

SERVER: invalid_design_document: Syntax error in the map function of the view `by_date': SyntaxError: Unexpected end of input (Couchbase::Error::View)
