Add ctx to job processing about goblero

[xamenyap]

I think we can achieve this by adding ctx as the first parameter for method Run() of Processor.
Something like this

type Processor interface {
	Run(ctx context.Context, j *Job) error
}

Is this what you mean? If yes, I can help with the issue

I thought maybe we could find a way to make ctx optional/ implicit, similarly to how its done in the http std library https://golang.org/pkg/net/http/#Request.Context ?
then make ctx a field on the Job,
ctx context.Context

any thoughts ?

Sure, that works too. Probably it's better to provide another method to *Blero to enqueue a job with Context, similar to how std lib provides http.NewRequest and http.NewRequestWithContext

// uses a default context.Background()
func (bl *Blero) EnqueueJob(name string, data []byte) (uint64, error) {
  jID, err := bl.queue.enqueueJob(context.Background(), name, data)
}

// use the provided context
func (bl *Blero) EnqueueJobWithContext(ctx context.Context, name string, data []byte) (uint64, error) {
  jID, err := bl.queue.enqueueJob(ctx, name, data)
}

Job context can be used like this in dispatcher

func (d *dispatcher) runJob(q *queue, pID int, p Processor, j *Job) {
	defer d.processorDone(pID)
	select {
	case <-j.ctx.Done():
		err := q.markJobDone(j.ID, jobFailed)
		if err != nil {
			fmt.Printf("markJobDone -> %v jobFailed failed: %v\n", j.ID, err)
		}
	default:
		// run the job
	}
}

thanks @xamenyap for the input, I'm closing this issue for now, it does not seem to be a priority at the moment
