Ensure triggering of callback in chord #397
base: main
Are you sure you want to change the base?
Conversation
If one task for whatever reason is executed twice the callback is never triggered because the chord will be deleted and the before the last task is executed. The last task then will raise a warning that the chord cant be found.

This makes sense, you could consider refrasing the warning so it indicates why it's emitted instead of what broke. Something like "Chord %s executed more tasks than expected"

I don't think this is correct, we have a header of 2, 1 is done, the other fails.
If a task in the header fails the chord is done and the callback is not called.
If this is the case, a ChordCounter object will remain in the db for every failed chord.
If one task for whatever reason is executed twice the callback is never triggered because the chord will be deleted before the last task is executed. The last task will then raise a warning that the chord can't be found.
