This is a major breaking changes breaking JS sdk (the interface of dispatchable call transfer) and other substrate-based chains (Currency trait).

One way to avoid the breaking change is add a new method and have the existing one calling the new one with a existence requirement AllowDeath to preserve existing semantics. The Currency trait should also have default implementation to avoid breaking other non substrate runtime modules.

expenses · 2019-11-02T09:07:05Z

yeah, we could perhaps do something like have transfer(origin, dest, value) that calls another balance api named something like transfer_more_complex(origin, dest, value, existence_requirement) with ExistenceRequirement.

Some nits and the core logic seems correct IMO. But I would take this slow and make sure
1- It is the desirable way to do this: probably get a sign-off from @xlc a/c @gavofyork. Maybe actually adding a secondary checked_transfer is better.
2- I am not sure how much this breaks (we are not changing storage right? old transactions cannot be replayed but I assume each transaction is executed agains the runtime at that block so it is okay?) but make sure it goes in smoothly.

xlc · 2019-11-02T11:27:17Z

Transactions are only valid for a given runtime version anyway so old unconfirmed transactions will be invalided anyway on runtime upgrade. So I mostly care about existing polkadot js code still works and existing runtime module outside of Substrate don't need unnecessary breaking changes (i.e. add new method with default implementation to a trait is fine, modify existing will be a breaking change). I understand breaking changes are sometimes unavoidable but in this case it not hard to avoid break one of the most commonly used method (transfer).

gavofyork · 2019-11-03T10:51:14Z

I'm ok with adding fn transfer_some which only transfers some of the balance, never all. If the value is too high, then the transfer will fail.

That said, I'm not sure if this really is a pain point given that we now have a means of getting the total fee. @joepetrowski under what conditions could an account accidentally be reaped when the exchange didn't want it to be given that we now have the RPC for determining fees?

kianenigma · 2019-11-04T10:02:34Z

Based on the discussion, yes in my opinion. That seems to be the safest option. yet, I won't be shocked if we change/remove it in the future.. but it doesn't seem like a lot of effort to add it so I'd be okay with that. The only complication I see would be for generic-asset. It should just call the normal transfer?

PS. This will be substrate's 4000'th PR once merged 🚀

expenses · 2019-11-04T10:05:06Z

Alright, I'll get on that. Sorry to disappoint, I think it's only the 4000th issue/PR opened unfortunately, not that special :P

xlc · 2019-11-04T10:12:09Z

generic-asset doesn't have existential deposit policy implemented at all so you shouldn't need to worry about it.

…acts test

joepetrowski

Should add a test and polish up the documentation (including adding transfer_some to the "Related functions" section of transfer).

Why not in impl Currency?

impl<T: Trait<I>, I: Instance> Currency<T::AccountId> for Module<T, I>

I don't want to hassle Currency implementors with writing an implementation of transfer_inner/transfer_some.

we could change transfer signature of Currency trait to:

fn transfer(transactor: &T::AccountId, dest: &T::AccountId, value: Self::Balance, liveness: ExistenceRequirement) -> Result {

I think that we should try to avoid breaking anything if we can. See @xlc's first comment in this PR.

Xlc comment is about not changing the Call. We can still have transfer and transfer_keep_alive in Call and have transfer(...., liveness: ExistenceRequirement) in Currency trait.

I feel generalizing the trait here doesn't harm

Depends if anyone else has implemented anything on it - third parties might have done. That said, if it is to be changed, now is the time to do it.

looks like the consensus is to ditch transfer_inner go use the trait? looks good and can be merged thereafter.
