// RegisterInterchainAccountWithOrdering is the entry point to registering an interchain account:
// - It generates a new port identifier using the provided owner string, binds to the port identifier and claims the associated capability.
// - Callers are expected to provide the appropriate application version string.
// - For example, this could be an ICS27 encoded metadata type or an ICS29 encoded metadata type with a nested application version.
// - A new MsgChannelOpenInit is routed through the MsgServiceRouter, executing the OnOpenChanInit callback stack as configured.
// - An error is returned if the port identifier is already in use. Gaining access to interchain accounts whose channels
// have closed cannot be done with this function. A regular MsgChannelOpenInit must be used.
//
// Deprecated: this is a legacy API that is only intended to function correctly in workflows where an underlying authentication application has been set.

We deprecated this in ibc-go/v6. We should discuss what it would mean to remove these APIs in favour of migrating directly to msg service router, and what users may be affected.

i.e. removing RegisterInterchainAccount public function used by "auth modules" and instead they depend on the baseapp MsgServiceRouter and send MsgRegisterInterchainAccount.

Thanks, @damiannolan. Yes, I agree we should discuss this. I was also thinking that if we get to ICS27 v2 this year, that might be a good moment to tackle that.

// Calling this API will result in all packet callbacks being routed to the underlying application.

// Please use MsgRegisterInterchainAccount for use cases which do not need to route to an underlying application.

// Prior to v6.x.x of ibc-go, the controller module was only functional as middleware, with authentication performed
// by the underlying application. For a full summary of the changes in v6.x.x, please see ADR009.
// This API will be removed in later releases.

I used the same godoc as for RegisterInterchainAccount. If someone thinks I should add something, let me know.

I added this function to allow setting the ordering, otherwise if the controller chain has a a custom auth module and tries to open a channel with a host chain that doesn't support unordered channels, any attempt to open new ICA channels will fail. Using this function, the controller chain has the option to use ordered ordering with chains that don't support unordered ordering.

I will open an issue to break the API of RegisterInterchainAccount to add the extra order parameter and also use UNORDERED ordering if NONE is passed.

portID, err := icatypes.NewControllerPortID(owner)
if err != nil {
return err
}

if k.IsMiddlewareDisabled(ctx, portID, connectionID) && !k.IsActiveChannelClosed(ctx, connectionID, portID) {
return errorsmod.Wrap(icatypes.ErrInvalidChannelFlow, "channel is already active or a handshake is in flight")
}

k.SetMiddlewareEnabled(ctx, portID, connectionID)

// use ORDER_UNORDERED as default in case ordering is NONE
if ordering == channeltypes.NONE {
ordering = channeltypes.UNORDERED
}

_, err = k.registerInterchainAccount(ctx, connectionID, portID, version, ordering)
if err != nil {
return err
}
