File Transport maxsize is not working as expect

See original GitHub issue

Hi All,

I find that when I define the file transport with setting as followed

const logger = new (winston.Logger)({
    transports: [
        new (winston.transports.File)({
            filename: config['log_file_name'],
            dirname: '/data/tmp/',
            //maxsize: 1000 * 1000 * 1024, // 1Gb
            maxsize: 102400, // 100 kb
            maxFiles: 1000,
            timestamp: function() {
                return Date.now()/1000|0;
            }
        })
    ],
    exitOnError: false
})

then, the final log size will be 4 times than the maxsize.

404K    rcv.log
400K    rcv1.log
240K    rcv2.log

According to the documentation, this result is not expected.

Thanks

I use the following code for transport initialization:

winston.add(winston.transports.File, {
  name: 'errors',
  filename: 'logs/errors.log',
  level: 'error',
  maxsize: 10,
});

And then:

server.listen(server.get('port'), () => {
  winston.info(`The server is running at http://localhost:${server.get('port')}/`);
  winston.error(new Error('asdsad'));
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
  winston.error('cvxcvxcvcxvxcvxcvxcvxc');
});

##Expected result:

several files, each file as small as possible.

##Actual result:

one big file with all messages
