In function readRow, parser._offset is great than parser._buffer.length. I don't know how to fix this.

var readRow = function(tableMap, parser, emitter) {
  var row = {}, column, columnSchema;
  var nullBitmapSize = Math.floor((tableMap.columns.length + 7) / 8);
  var nullBuffer = parser._buffer.slice(parser._offset, 
                                        parser._offset + nullBitmapSize);                                     
  var curNullByte, curBit;
  parser._offset += nullBitmapSize;

  for (var i = 0; i < tableMap.columns.length; i++) {
    curBit = i % 8;
    if(curBit === 0) curNullByte = nullBuffer.readUInt8(Math.floor(i / 8));
    column = tableMap.columns[i];
    columnSchema = tableMap.columnSchemas[i];
    if((curNullByte & (1 << curBit)) === 0){
      row[column.name] =
        Common.readMysqlValue(parser, column, columnSchema, tableMap, emitter);
    }else{
      row[column.name] = null;
    }
  }
  return row;
};
