Doesn't log anything to file transport when handleExceptions is true and exitOnError is true

[gremo]

Please tell us about your environment:

• winston version?
  • [ ] winston@2
  • [x ] winston@3
• node -v outputs: v8.11.2
• Operating System? (Windows, macOS, or Linux) Windows 10 x64
• Language? (all | TypeScript X.X | ES6/7 | ES5 | Dart) TypeScript 2.7.2

What is the problem?

Doesn't log anything to file transport with handleExceptions: true and exitOnError: true (default value).

What do you expect to happen instead?

Error is logged and then the process exits.

Other information

// Create winston logger for writing to the env log
const logger = winston.createLogger({
  level: 'debug',
  exitOnError: true,
  transports: [
    new winston.transports.File({
      handleExceptions: true,
      filename: `${__dirname}/logs/dev.log`,
      format: winston.format.combine(
        winston.format.timestamp({ format: 'YYYY-MM-DD HH:mm:ss' }),
        winston.format.printf(info => `[${info.timestamp}] ${info.level}: ${info.message}`)
      )
    })
  ]
});

logger.debug('throwing...');
throw new Error('foo');

If I set exitOnError: false , logging works again (but this is not what I need):

[2018-06-16 19:36:53] debug: throwing...
[2018-06-16 19:36:53] error: uncaughtException: foo
Error: foo

This seems like a duplicate of #1289 which has a pending PR #1355 that would hopefully fix your problem as well. (Waiting for some discussion with @indexzero before merging that in.) Thanks for bringing this up!
