Status of Parent task not depending on progress vs.total

[Skrattoune]

Hi,
My tasks are organised as a set of sub-tasks

completion of each sub-task is adding 1 to the progress of the parent task

however if you look at the first snapshot that shows only the columns visible without scrolling, one could think that all activities are complete and that it would be ok to switch off the server.

But if you scroll right to see the progression data, the situation is very different:

At the moment, the status of the Parent task is not related at all to the task progression (TaskModel.progress_info[0] vs. TaskModel.total)

In my use case, that would be necessary to take task progression into account when a total is specified.

How could I ensure that the "signal_complete" is not sent before each sub-task is complete?
and that it is sent once the last sub-task has been completed?

That's on the Huey side: If your main task just fires the sub tasks, then it's completed and Huey send this signal. Don't know if there is something in Huey to recognized this.

Think you have to "wait" in your main task that all sub task are finished... But if you wait, than maybe to ran into a deadlook, if some of the sub tasks has a problem?!?

Quick idea: Maybe the main task can "wait" until all sub tasks signals are one of these:

Thanks Jens,

Exploring further the code for v0.5.0, I had another idea that will require less access to database.
(by the way : great simplification ! congrats)

I'm testing this idea locally since yesterday.
I'll push it between today and week-end.

I'll propose you as well some things I have been using and could prove useful to other users

Now you have the different PRs
don't hesitate to adapt to your own style
or to ask clarifications if some things are not self-explaining

I saw also that one of the automatic test didn't succeed, but I have no clue why.
I'll need your input there.
Have fun !

I just realized this morning that in the admin, the parent_task with the sub-task which was latest updated only appeared in 4th position.
This is not very logic, and it makes it difficult to quickly assess where we are in the execution when a number of tasks have been launched.

• I therefore propose to update update_dt of the parent task when a signal is received from a sub-task

Sounds a good idea!

I saw you merged than reverted.
It didn't work for you ?
