Idea #3898
Updated by Tom Clegg over 9 years ago
Before validation:
* If state has changed to Running, set started_at to now
* If state has changed to Failed or Complete, set finished_at to now
* If state has changed to Cancelled, set cancelled_at to now
* If state has changed at all, set running and success (see below)
* If state has not changed, and any of {running, success, cancelled_at} have changed, update state accordingly
* If state is nil, update state according to running, success, cancelled_at
Validation:
* If state has changed to Running, and is_locked_by_uuid is nil, return false
Translating from running/success/cancelled_at to state:
|running |success |cancelled_at |state |
|any |any |not nil |Cancelled|
|any |false |nil |Failed |
|any |true |nil |Complete |
|true |nil |nil |Running |
|false |nil |nil |Queued |
Translating from state to running/success:
|state |running |success |
|Queued |false |nil |
|Running |true |nil |
|Cancelled |false |false |
|Failed |false |false |
|Complete |false |true |
