[pallet-balances] `burn_allow_death` extrinsic #3964

Dinonard · 2024-04-03T11:40:19Z

Adds an additional extrinsic call to the pallet-balances to burn tokens.
Depending on the keep_alive flag, the call might or might not reap the account.

Required modification of the fungible's Mutate trait, burn_from function to allow the Preservation argument.

TODO

run benchmarks & update weights
make sure prdoc is required & properly formatted

Related issue: #3943

ggwpez · 2024-04-03T11:50:40Z

substrate/frame/balances/src/lib.rs

+		#[pallet::weight(T::WeightInfo::burn_allow_death())]
+		pub fn burn_allow_death(
+			origin: OriginFor<T>,
+			#[pallet::compact] value: T::Balance,


An additional call is overkill, but a keep_alive: bool similar to thetransfer_all would be fine i think.

I don't mind doing that, but will need to change this function signature:
https://github.com/paritytech/polkadot-sdk/blob/master/substrate/frame/support/src/traits/tokens/fungible/regular.rs#L260

It might end being a slightly lager change, hope that's ok.

Updated per request.

Will need help/suggestion with the remaining TODOs in the PR summary:

running benchmarks & updating weights (I cannot trigger the job)

check whether prdoc is ok

I know you said in another PR that current review process isn't sustainable (I assume due to human resources), but is there someone else we can ask to take a look at the PR?

@ggwpez sorry for the tag but could you please give a timeline when this can be checked out? Can we get someone else to review it?

Yea, it is best to ask in chat for review. We have the open #fellowship-open-channel:parity.io channel for that. I invited you.
Otherwise it can get lost or not have any priority...

Thanks a lot!

Dinonard · 2024-05-07T05:45:24Z

Thanks a lot, all the weight files have been updated!

Now just to get a second review 🙂

liamaharon · 2024-05-07T06:42:12Z

@Dinonard thanks for this! if you want a tip, you can put your Polkadot address in the PR description like

polkadot address: <SS58 Address>

then tag me and I'll initiate it.

Dinonard · 2024-05-07T06:55:46Z

@liamaharon thanks! I will pass since I'm already part of Astar team, and taking a tip for this seems wrong 🙂

It seems I was premature in celebrating benchmark success though, rococo is still missing 🙃.

Can you please trigger it?
I assume only bot bench polkadot-pallet --pallet=pallet_balances --runtime=rococo-dev?

liamaharon · 2024-05-07T06:58:15Z

Hmm yeah it's also missing westend weights. @mordamax any ideas how we can bench all runtimes?

Dinonard · 2024-05-08T06:11:11Z

The only files missing weight updates are:

polkadot/runtime/rococo/src/weights/pallet_balances_balances.rs
polkadot/runtime/rococo/src/weights/pallet_balances_nis_counterpart_balances.rs

hence my suggestion to try bot bench polkadot-pallet --pallet=pallet_balances --runtime=rococo-dev.
(not sure it will work 🙃 )

mordamax · 2024-05-08T06:24:40Z

that issue is known, we have it to fix in our backlog,
lets try ) im not sure either

bot bench polkadot-pallet --pallet=pallet_balances --runtime=rococo-dev

command-bot · 2024-05-08T06:24:43Z

@mordamax option '--runtime ' argument 'rococo-dev' is invalid. Allowed choices are rococo, westend.

mordamax · 2024-05-08T06:24:56Z

@Dinonard looks good now. I will need to make sure those ones are part of bench-all pallet 👍
