When using body stream and chunk in 1.9.3-p392, when it calls 

    def send_request_with_body_stream(sock, ver, path, f)
      unless content_length() or chunked?
        raise ArgumentError,
            "Content-Length not given and Transfer-Encoding is not `chunked'"
      end
      supply_default_content_type
      write_header sock, ver, path
      wait_for_continue sock, ver if sock.continue_timeout
      if chunked?
        while s = f.read(1024)
             sock.write(sprintf("%x\r\n", s.length) << s << "\r\n")
        end
        sock.write "0\r\n\r\n"
      else
        while s = f.read(1024)
          sock.write s
        end
      end
    end

it often causes the receiving server to close the connection as the length is apparently wrong.

In Ruby2, the code has been changed to using bytesize instead of length, after quite a bit of debugging,

        while s = f.read(1024)
             puts sprintf("%x\r\n", s.length)
             puts sprintf("%x\r\n", s.bytesize)
             sock.write(sprintf("%x\r\n", s.length) << s << "\r\n")
        end

quite a number of times, the two values are not matching. And when i change the code to use s.bytesize instead of s.length, the problem never appears again
