JobStatus

This module contains constants and lists for the possible job states.

DIRAC.WorkloadManagementSystem.Client.JobStatus.CHECKING = 'Checking'
DIRAC.WorkloadManagementSystem.Client.JobStatus.COMPLETED = 'Completed'
DIRAC.WorkloadManagementSystem.Client.JobStatus.COMPLETING = 'Completing'
DIRAC.WorkloadManagementSystem.Client.JobStatus.DELETED = 'Deleted'
DIRAC.WorkloadManagementSystem.Client.JobStatus.DONE = 'Done'
DIRAC.WorkloadManagementSystem.Client.JobStatus.FAILED = 'Failed'
DIRAC.WorkloadManagementSystem.Client.JobStatus.JOB_STATES = ['Submitting', 'Received', 'Checking', 'Staging', 'Waiting', 'Matched', 'Rescheduled', 'Running', 'Stalled', 'Completing', 'Done', 'Completed', 'Failed', 'Deleted', 'Killed']

Possible job states

class DIRAC.WorkloadManagementSystem.Client.JobStatus.JobsStateMachine(state)

Bases: DIRAC.Core.Utilities.StateMachine.StateMachine

Jobs state machine

__init__(state)

c’tor Defines the state machine transactions

getLevelOfState(state)

Given a state name, it returns its level (integer), which defines the hierarchy.

>>> sm0.getLevelOfState('Nirvana')
    100
>>> sm0.getLevelOfState('AnotherState')
    -1
Parameters

state (str) – name of the state, it should be on <self.states> key set

Returns

int || -1 (if not in <self.states>)

getNextState(candidateState)

Method that gets the next state, given the proposed transition to candidateState. If candidateState is not on the state map <self.states>, it is rejected. If it is not the case, we have two options: if <self.state> is None, then the next state will be <candidateState>. Otherwise, the current state is using its own transition rule to decide.

Examples

>>> sm0.getNextState(None)
    S_OK(None)
>>> sm0.getNextState('NextState')
    S_OK('NextState')
Parameters

candidateState (str) – name of the next state

Returns

S_OK(nextState) || S_ERROR

getStates()

Returns all possible states in the state map

Examples

>>> sm0.getStates()
    [ 'Nirvana' ]
Returns

list(stateNames)

setState(candidateState, noWarn=False)
Makes sure the state is either None or known to the machine, and that it is a valid state to move into.

Final states are also checked.

Examples

>>> sm0.setState(None)['OK']
    True
>>> sm0.setState('Nirvana')['OK']
    True
>>> sm0.setState('AnotherState')['OK']
    False
Parameters

state (None or str) – state which will be set as current state of the StateMachine

Returns

S_OK || S_ERROR
