Feat/new register runtx flows #52

seantking · 2021-06-23T16:39:35Z

This PR updates the core interchain account module based on the new specification: cosmos/ibc#567

How to run

@milosevic I think this may be an issue.

We need to have a way to deterministically generate the interchain account address on both chains from an identifier. Right now this works as I'm just running the same chain x2 but I guess this would return a different address depending on chain configuration?

The controller chain needs to know what the registered account address is (perhaps for sending ics20 transfers). As we are registering the account in the channel handshake callbacks the sending side has no way to retrieve what the interchain account address is.

Although, the more I think on it, it's not a must-have. We can always set the interchain address on the controller side at a later time (maybe parse it from an ack packet) or just have the host side have a query to get the interchain account address (for the short term this is totally fine)

This seems fine to me from a deterministic point of view. Are you worried about collisions?

I think the only way around this, for now, is to add another command to set the address of the registered account on the controller side (we will need to parse it from the IBC ack). We need the address of the interchain account for practically every msg we want to send.

I was thinking maybe it would be better to store the full Channel type rather than the id.

I think the ID is fine, any reason to store full channel?

I think the ID is also fine. Agreed.

We could potentially try to reopen the channel when it closes here. Perhaps this adds to much edge case complexity tho.

Don't try to reopen. Just open a new channel with the same portID

And "unset" the active channel here

+	sourceChannelEnd, found := k.channelKeeper.GetChannel(ctx, sourcePortId, activeChannelId)


I need to check here if the channel is closed. It actually isn't doing this check at the moment. The error that returns from TryRunTx if there is no active channel is just the standard IBC error (because the channel is not open). It works as intended though, just not the correct error message.

I updated this to use the newer channeltypes.Acknowledgement. The latest ibc-go is using a newer standard but I'm still using an older version of the SDK at the moment.

@milosevic Every registered port is prefixed with this. I was thinking it is a good way to track what version of ics27 an account was registered under (this may be useful for migrating accounts in the future, or even just to help with port collisions)

I'm going to update the grpc_query stuff today, and probably add a new cli command for querying for interchain accounts.

Excellent work!! This looks so much cleaner!

My main requests are just copies from what i said in spec PR, mainly around the handshake callbacks

"unset" active channel

I'm thinking we can create some issues for the work that is left to do. I.e. unset active channels + additional checks in the channel callbacks.

This will allow anyone to close a channel. If you want to let people voluntarily close a channel, you need to do at least some kind of authentication here
