Multiple callbacks active at the same time

Currently most of my state logic is contained in on_enter callbacks. Since in some states I have to periodical checks, these callbacks run until the sate finishes.

Now I just noticed that it is possible that the on_enter CB of the following state is activated, while the old callback hasn’t finished yet. Is this behaviour desired?

In my case I probably will have to start using mutexes … 😖

Have been pondering about my implementation a bit.

So, if I would move the trigger call out of the callback, then I would need to create separate worker methods. Those would do the actual work and when finished trigger the transition to the next state.

Now looking at implementing this, I cannot see another straight-forward approach apart from the “if state A do this, if state B do that”, which you have mentioned in your blog post:

if state == 'consent' and user_response == 'Agree':
    state = 'demographics'
elif state == 'demographics' and validate_demographics(data):
    save_demographics()
    state = 'personality'
...

But then again, I started using this package in order to avoid this approach.

Am I missing something here? Do you have more advanced sample code some where?

In my case there are several states with while loops in which another process is polled for information to decide on state transitions depending on the retrieved data.

Closing this and labeling wontfix for now. Still open to ideas though.
