[Bug]: Type cosmossdk_io_math.LegacyDec (from package cosmossdk.io/math) not show correctly if the cli generated using autocli

[QuocThi]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

I am facing an issue with the client cli command generated using autocli. Any Msg response from server that has field with type DecCoin (underlying type is cosmossdk_io_math.LegacyDec) will be shown incorrectly. Here are some examples:
I have a custom module that will return a DecCoin type when query balances of account:
message QueryBalancesResponse { repeated cosmos.base.v1beta1.DecCoin coins = 1; }

NOTE: the correct balances is: 4000000000ntoken OR 4token

When using autocli to generate the client query cmd it show incorrect balances:

binaryd q gm balances address1q9mhu97ju0qckqgqf5fnhdqe5el63kzq33phdc                                                                                                                                                           
coins:
- amount: "4000000000000000000"
  denom: token

when using the cosmos's bank module to show, it shows correctly (because cosmos's bank using: cosmos.base.v1beta1.Coin):

binaryd q bank balances address1q9mhu97ju0qckqgqf5fnhdqe5el63kzq33phdc                                                                                                                                                         
balances:
- amount: "4000000000"
  denom: ntoken

If I use custom command (which uses client.PrintProto() from package "github.com/cosmos/cosmos-sdk/client") it also print output correctly.

binaryd q gm balances address1q9mhu97ju0qckqgqf5fnhdqe5el63kzq33phdc                                                                                                                                                            
coins:
- amount: "4.000000000000000000"
  denom: token

The gov module also show wrong number if the Params have type DecCoin.

    }
  ],

        - amount: "10000000000000000000000"

     ....

My previous solution is using EnhanceCustomCommand: true and keep our custom client cli to use the client.PrintProto() for our custom modules. But problem still happen with cosmos's core module like staking, gov. Here is the list of comos's module still use DecCoin type.

Cosmos SDK Version

0.50.3

How to reproduce?

Hi!

What's your x/tx version?
EDIT: Never mind, I am confusing this with another issue.

[julienrbrt]

Thank you for finding this, I can reproduce.

https://v050.simapp.zone:1317/cosmos/distribution/v1beta1/community_pool

{
  "pool": [
    {
      "denom": "stake",
      "amount": "435835.220000000000000000"
    }
  ]
}

While simd q distribution community-pool isn't properly marshalled.

We need to define another encoder like this: https://github.com/cosmos/cosmos-sdk/blob/main/client/v2/autocli/query.go#L161-L186, as apparently, x/tx marshals cosmos.base.v1beta1.DecCoin differently.

Hi @julienrbrt ,
so this should be fixed in autocli package from upstream repository and included in the next release right?
Also here is the list of cosmos's core module Msg that uses DecCoin type, I attached but it don't show up.
cosmos_types_use_DecCoins.txt

[julienrbrt]

We'll release a client/v2 v2.0.0-beta.2 this week (#19530) and it will be usable in any v0.50.x release.
We have our monthly patch planned for this week as well.

[QuocThi]

Hi @julienrbrt,
Seem the v2.0.0-beta.2 still not released yet? I'm checking from this page and see the latest version still :v2.0.0-beta.1: https://pkg.go.dev/cosmossdk.io/client/v2.
Do I check on the right site?

Thanks

[julienrbrt]

Correct, we've been backporting things, and the one PR that we want merged before beta.2 is still wip: #19530

Feel free to follow the issue above to be alerted.

Hi @julienrbrt,
One more type I missed is cosmossdk.io/math.LegacyDec also need the same fix as DecCoin, you can reproduce by using below queries:

binaryd q staking validators ==> the commission.delegator_shares is wrong.
binaryd q staking delegations <delegator_address> ==> the delegation.shares is wrong.

[QuocThi]

Hi @julienrbrt,
Any update on which release will contain the fix of these two bugs?

Thanks
