job status transition in ReqClient vs JobStatus

[iueda]

This code suggests transition of job status from 'Completed' to 'Killed' https://github.com/DIRACGrid/DIRAC/blob/v8.0.51/src/DIRAC/RequestManagementSystem/Client/ReqClient.py#L371-L373

            if jobStatus == JobStatus.COMPLETED:
                ...
                elif jobMinorStatus == JobMinorStatus.MARKED_FOR_TERMINATION:
                    # If the job has been Killed, set it Killed
                    newJobStatus = JobStatus.KILLED
            ...
            stateUpdate = stateServer.setJobStatus(jobID, newJobStatus, JobMinorStatus.REQUESTS_DONE, "RMS")

but there is no such state transition defined in https://github.com/DIRACGrid/DIRAC/blob/v8.0.51/src/DIRAC/WorkloadManagementSystem/Client/JobStatus.py#L88

            COMPLETED: State(11, [DONE, FAILED], defState=COMPLETED),

Which is the policy?

Just few days ago we created https://github.com/DIRACGrid/DIRAC/pull/7794 but we discussed that it would not make sense to set jobs from "COMPLETED" to "KILLED". The code above was introduced in https://github.com/DIRACGrid/DIRAC/pull/5650 and I do not find its operational source. I can see in LHCb that we have atm 2 jobs "DONE" with minorStatus "Marked for termination". I need some arguments on how to continue.

We have jobs in Status='Completed' and MinorStatus='Marked for termination'

Looking into the job LoggingInfo

JobWrapper           Completed   Pending Requests                   ... 
RMS(SM)              Completed   Requests done                      ...

Supposedly, the user killed the job while it was in RMS, with Status='Completed'. The job could not be killed because the state transition is not allowed, and RMS could not set it to 'Killed' for the same reason, I imagine.

I think In this case the final job state should be Done or Failed as in the checks just above. So, the lines https://github.com/DIRACGrid/DIRAC/blob/v8.0.51/src/DIRAC/RequestManagementSystem/Client/ReqClient.py#L371-L373 can be suppressed. If we have this case, it means that the job kill command was given too late to influence the job execution, the job was already executed, so the kill command should be just ignored. This can be coded in the JobManager.__killJob(): set the status to Killed and only if it is successful - set the minor status to "Marked for termination" as a separate call

That may be right from the system point of view. But requests may take time to be processed, then the jobs stay in the non-terminal status even when the users would like to get rid of them.

I thought "Marked for termination" is to be set to MinorStatus when the Status cannot be immediately set to "Killed", so that the status can go to "Killed" when there is no more bloker.
