Not sure how this ended up as commitmenttypes I see the import previously would've been incorrect also.
It should be controllertypes.SubModuleName.

Ah right, I was wondering about that actually, I changed the import to be inline with other imports in the file. I can update this now.

I think the dangers of types as the import alias.

small nit:

Suggested change

return []byte(fmt.Sprintf("%s/ports/%s", host.KeyChannelEndPrefix, portPrefix))

return []byte(fmt.Sprintf("%s/%s/%s", host.KeyChannelEndPrefix, host.KeyPortPrefix, portPrefix))

I renamed this to avoid shadowing the built in cap function.

Would it make sense to place this function in types/keys.go instead?

good suggestion, done!

LGTM, just would like a little testing in 04-channel as well. Nice work thus far!

We normally favour using ID over Id in naming (except proto generated code).

Suggested change

portIdWithOutPrefix := ibctesting.MockPort

suite.chainA.GetSimApp().IBCKeeper.ChannelKeeper.SetChannel(suite.chainA.GetContext(), portIdWithOutPrefix, ibctesting.FirstChannelID, channeltypes.Channel{

ConnectionHops: []string{ibctesting.FirstConnectionID},

ConnectionHops: []string{ibctesting.FirstConnectionID},

})

We only favor "Id" in proto naming because using "ID" messes with the grpc gateway generation (I'm not sure why nor if this is still an issue, but it was when we initially switched to proto)

Should we consider naming this function to align with GetAllChannels below which returns []types.IdentifiedChannel also?

Maybe GetAllChannelsWithPortPrefix or GetAllPortPrefixedChannels?

I don't feel particularly strongly but just a thought. cc. @crodriguezvega @colin-axner

I like GetAllChannelsWithPortPrefix to stay consistent

Sounds good to me. I have no preference

I added this function as I saw that the order of the values returned in GetAllChannels is not necessarily in the order they were added.
