Abstract: A job state machine may transition to a downloading state in response to a start message on the job pipeline, wherein the job object causes job data to be downloaded to the device when the job state machine is in the downloading state. The job state machine may transition to an installing state in response to an assertion message on the job pipeline, wherein the job object causes downloaded job data to be installed on the device when the job state machine is in the installing state. The job state machine may transition to a finished state when the job data is installed on the device. The job state machine may be recoverable to the waiting state, the downloading state, or the installing state in response to a job object failure while the job state machine is in the waiting state, downloading state, or installing state, respectively.
