How to add more attempts in a job

[jquequezana]

Hello, maybe someone can help me with that questions ...
Would like to know how can add more attempts to a job based on the flow

First I create my job with 3 attempts....
After... the work fail 2 times but based on some event I need to add 1 attempt more to my job.

My question is how to get the current max attempts and add x more attempts, that is because if the event happens again need add 1 attempt more

Second question is how to fail a job with no more attempts;

Regards

I think I found the solution to my second question is ok ?

61 job.attempts(0).save();
62 done(new Error('not found'));

About my first question What is the correct way to do that?
A.

job._max_attempts++;
job.set('max_attempts', job._max_attempts);

B.

job.attempts(++job._max_attempts).save();
