`JobUtils.skipForward` with monthly job doesn't work correctly #851

Open tokuhirom opened 7 years ago

tokuhirom commented 7 years ago

Please look this code.

  "Can skip forward a job with a monthly period" in {
    val schedule = "R/2012-01-01T00:00:01.000Z/P1M"
    val job = ScheduleBasedJob(schedule, "sample-name", "sample-command")
    (1 to 365).map {i =>
      val now = new DateTime(2017, 1, 1, 0, 0).plusDays(i)

      // Get the schedule stream, which should have been skipped forward
      val stream = JobUtils.skipForward(job, now)
      val scheduledTime = Iso8601Expressions
        .parse(stream.get.schedule, job.scheduleTimeZone)
        .get
        ._2

      // Ensure that this job runs on the first of next month
      System.err.println("now:%s scheduledTime:%s".format(now, scheduledTime))
      scheduledTime.dayOfMonth().get must_== 1
    }
  }

The output is following. This output seems strange. scheduledTime should after than now but it's not in some case.

The bug is around this patch. At this pr, it divides elapsed seconds by seconds in the current month. https://github.com/mesos/chronos/pull/800

The number of days in a month is different for each month. February is until 28th or 29th. January is until the 31st. As a result, the current implementation may not be the expected behavior.

Current test case uses new DateTime(). It gets current date and time. In my opinion, that such a test case is not good because the result will be different depending on the date and time of execution.
