      Correct job time limit for sched/backfil and job has QOS with NO_RESERVE flag · 4652e982
      Morris Jette authored
      If sched/backfill starts a job with a QOS having NO_RESERVE and not job
      time limit, start it with the partition time limit (or one year if the
      partition has no time limit) rather than NO_VAL (140 year time limit);
      
      If a standby job, which in this
      case has the NO_RESERVE flag set, is submitted
      without a time limit, and is backfilled, it
      will get an EndTime waaayyyy into the future.
      
      JobId=99 Name=cmdll
         UserId=eckert(1043) GroupId=eckert(1043)
         Priority=12083 Account=sa QOS=standby
         JobState=RUNNING Reason=None Dependency=(null)
         Requeue=1 Restarts=0 BatchFlag=1 ExitCode=0:0
         RunTime=00:00:14 TimeLimit=12:00:00 TimeMin=N/A
         SubmitTime=2012-12-20T11:49:36 EligibleTime=2012-12-20T11:49:36
         StartTime=2012-12-20T11:49:44 EndTime=2149-01-26T18:16:00
      
      so I looked at the code in /src/plugins/sched/backfill:
      
                      if (job_ptr->start_time <= now) {
                              int rc = _start_job(job_ptr, resv_bitmap);
                              if (qos_ptr && (qos_ptr->flags & QOS_FLAG_NO_RESERVE)){
                                      job_ptr->time_limit = orig_time_limit;
                                      job_ptr->end_time = job_ptr->start_time +
                                                          (orig_time_limit * 60);
      
      Using the debugger I found that if the job does not have a specified
      time limit, the job_ptr->time_limit is equal to NO_VAL when it hits
      this code.
