| yinweimac | saggi? | 12:42 |
| yinweimac | can i ask what's the difference between get_prev_task and get_post_task? | 12:43 |
| saggi | the former is when you visit the node and post when you leave | 12:44 |
| saggi | yinweimac: ^^^^^ | 12:44 |
| yinweimac | hmm, per my understanding, on entering the node, we usually make task flow of this node | 12:45 |
| yinweimac | on leaving the node, which means we have visited all of its children, then we build dependency between its own task flow to the task flow returned by its chidlren nodes. | 12:46 |
| yinweimac | does get_post_task involve making new tasks? | 12:47 |
| yinweimac | I mean, is it possible that get_post_task needs children tasks as its input? | 12:51 |
| yinweimac | say, for restoration, vm node can build vm_task, and its children vol1 node could build vol1_task | 12:52 |
| yinweimac | when the node is leaving, the vm node needs create an attach_vol_task and compose the 3 as vm_task, vol1_task, attach_vol_task->vm_task, attach_vol_task->vm_task | 12:53 |
| yinweimac | it seems to me that only one function of get_task_flow(children_task_flow) would be enough. | 12:54 |
| yinweimac | i don't see the difference between enter node and leave node | 12:56 |
| yinweimac | only the dependency on the tasks matters. whether you create task before or after the children node traverse doesn't matter, right? | 12:57 |
| yinweimac | Pls. let me know your idea when you're available. | 12:57 |
