You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: client.rb
    path of file: ./repos/stackneveroverflow/vendor/bundle/ruby/2.3.0/gems/puma-3.9.1/lib/puma
    
    the code of the file until where you have to start completion: class IO
  # We need to use this for a jruby work around on both 1.8 and 1.9.
    
    def reset(fast_check=true)
      @parser.reset
      @read_header = true
      @env = @proto_env.dup
      @body = nil
      @tempfile = nil
      @parsed_bytes = 0
      @ready = false

      if @buffer
        @parsed_bytes = @parser.execute(@env, @buffer, @parsed_bytes)

        if @parser.finished?
          return setup_body
        elsif @parsed_bytes >= MAX_HEADER
          raise HttpParserError,
            "HEADER is longer than allowed, aborting client early."
        end
