Needs to be implemented once #1976 is merged and released.

Two options have been floated:

  1. write a script that scrapes extrinsics for accounts that had their consumers erroneously incremented and generates a migration to decrement them
  2. introduce fn fix_consumers(origin, who: AccountId) in the System pallet, with an additional frame_system::Config::CountConsumers trait with a function fn count_consumers(who: &AccountId) -> u32, which could possibly be written on a per-pallet basis and composed in a tuple and used by AllPalletsWithSystem`.

also see #1970

2 will be useful and we can easily convert it into a try_runtime invariant to ensure the consistency in future

Has there been any progress/update to this? We have recently found pools are failing to be destroyed because of this bug.

I think that it would help to have #4398 deployed before we start starting migrations for the references...

can I take this issue? @ggwpez @liamaharon

I think there is no clear forward yet. I guess the count_consumer approach could work, but its a bit complicated in general.

@liamaharon

I think the way forward is to scrape bad update_locks invocations (#1970), and write a migration to fix consumers based on that. A bit fiddly, but should be feasible I think?

Could work, but we have this issue not just on Polkadot - but presumably on all chains...
What you mean is the go through an archive and record and erroneous double-decrements?

@liamaharon

Yes, write a script that replays transactions and checks after every lock/unlock whether there was an erroneous increment/decrement. Then it crafts a migration which can be inserted into the runtime to fix them.

Allow pool to be destroyed with an extra (erroneous) consumer referen…
2e36f57 
…ce on the pool account (#4503)

addresses #4440 (will
close once we have this in prod runtimes).
related: #2037.

An extra consumer reference is preventing pools to be destroyed. When a
pool is ready to be destroyed, we
can safely clear the consumer references if any. Notably, I only check
for one extra consumer reference since that is a known bug. Anything
more indicates possibly another issue and we probably don't want to
silently absorb those errors as well.

After this change, pools with extra consumer reference should be able to
destroy normally.

Is there any news about allowing currently 'destroying' pools to be destroyed?

#4503 i suppose. Should be in the SDK 1.13 release.

Pools can be destroyed now. I believe this issue can be closed.

There was a fix for pools: #4503 but the general issue is not addressed by this.
