Make `IdentityInfo` generic in `pallet-identity` #1661

georgepisaltu · 2023-09-21T11:03:15Z

Fixes #179

Description

This PR makes the structure containing identity information used in pallet-identity generic through the pallet Config. Additionally, the old structure is now available in a separate module called simple (pending rename) and is compatible with the new interface.

Another change in this PR is that while the additional field in IdentityInfo stays for backwards compatibility reasons, the associated costs are stil present in the pallet through the additional function in the IdentityInformationProvider interface. This function is marked as deprecated as it is only a temporary solution to the backwards compatibility problem we had. In short, we could have removed the additional fields in the struct and done a migration, but we chose to wait and do it off-chain through the genesis of the system parachain. After we move the identity pallet to the parachain, additional fields will be migrated into the existing fields and the additional key-value store will be removed. Until that happens, this interface will provide the necessary information to properly account for the associated costs.

Additionally, this PR fixes an unrelated issue; the IdentityField enum used to represent the fields as bitflags couldn't store more than 8 fields, even though it was marked as #[repr(u64)]. This was because of the derive implementation of TypeInfo, which assumed u8 semantics. The custom implementation of this trait in 0105cc0 fixes the issue.

Currently the changes in this PR keep the additional fields in the IdentityInfo struct, so no migration would be needed. However, the purpose of this PR was to make the identity information generic and, because additional fields in a Vec inside the IdentityInfo struct is an implementation detail, the costs in terms of deposit and weight associated with these additional fields are no longer accounted for in the extrinsics of this pallet. Below are the options on how to deal with the additional fields problem:

Add a function in the IdentityInformationProvider trait to somehow query for added costs besides some agreed upon standard cost. It could be bytes stored, number of "unnecessary" entries or something similar. Convert the output of that function to an amount reserved for the storage used and some extra weight for processing.
Use one dedicated field for a hash/image. Any information that is not considered useful by the system but is still wanted by users is currently stored in this additional field. While a dedicated field for this "extra" information verifiably stores a "summary", the actual info is stored somewhere else, off-chain maybe.
Remove it altogether as the purpose of the pallet is to judge information publicly. It's arguable non-standardized, custom fields and their judgements:
a. do not have the same relevance as the standardized ones
b. are more prone to typos and errors
c. are more difficult to interact with from a UX perspective

Options 2 and 3 will require migrations of the IdentityOf map while option 1 would not require any. However, with a transition of the identity pallet to a system parachain we can do the migration at genesis and we would not need to worry about the additional fields costs not being accounted for if we freeze any calls to the pallet so that users can't change their identities anymore (which would be required in the build up of the move). IdentityFields itself doesn't require a migration since it's just a BitFlag of a u64 and as long as we don't remove/change existing fields in IdentityField, it's backwards compatible. If we're looking for the best time to get rid of additional fields in the identity information, the genesis of the system chain would be it.

In order to safely merge this PR without accounting for the additional fields costs, we must merge the freeze of the calls to the pallet extrinsics before the next release or remove them altogether.

My personal choice is option 3 because it leaves the door open to add new fields in the future (such as the hash/image field described in option 2) in a backwards compatible way.

Just a note @georgepisaltu I was planning to migrate the identity pallet as per #226 but just noticed your PR so happy to make a PR off of your branch here or work on a different one instead if you'd prefer

Work on this branch, the changes are kind of related. I'll rebase the branch and resolve the conflicts as soon as possible.

From just reading the description, the changes that you are making are pretty orthogonal to making the identity type generic so it should be save. Feel free to open a draft PR regardless of the target branch when you have something :)

@georgepisaltu I'm happy to try to rebase if you're busy with other stuff

@georgepisaltu I'm happy to try to rebase if you're busy with other stuff

I pushed the merge, I'll have to move the polkadot/kusama pallet configuration and weights to a different PR in the fellowship I think. The rest of it should be pretty much the same. Let me know if it helps.

You can remove the code below and use the impl_codec_bitflags macro from there
P. S. Previously we had a different enumflags2 version for the identity pallet and nfts, but since we synced the versions now, we could extract that macro into a common folder and re-use the code

Unfortunately it doesn't work because of the generics, but I don't think it's too ugly either way.

hmm.. is it possible to avoid that generic? I think it could work without it, but maybe I'm missing smth

Summing up a recent discussion:

Adding the additional_fields method either as "deprecated" or "experimental" as intermediate solution.
Migrating a few fields like "github" or "discord" over once we have the proper fields and deleting all the other fields.
Removing the additional_fields after the transition period.

This PR is a follow up to paritytech#1661 - [x] rename the `simple` module to `legacy` - [x] fix benchmarks to disregard the number of additional fields - [x] change the storage deposits to charge per encoded byte of the identity information instance, removing the need for `fn additional(&self) -> usize` in `IdentityInformationProvider` - [x] ~add an extrinsic to rejig deposits to account for the change above~ - [ ] ~ensure through proper configuration that the new byte-based deposit is always lower than whatever is reserved now~ - [x] remove `IdentityFields` from the `set_fields` extrinsic signature, as per [this discussion](paritytech#1661 (comment)) > ensure through proper configuration that the new byte-based deposit is always lower than whatever is reserved now Not sure this is needed anymore. If the new deposits are higher than what is currently on chain and users don't have enough funds to reserve what is needed, the extrinisc fails and they're basically grandfathered and frozen until they add more funds and/or make a change to their identity. This behavior seems fine to me. Original idea [here](paritytech#1661 (comment)). > add an extrinsic to rejig deposits to account for the change above This was initially implemented but now removed from this PR in favor of the implementation detailed [here](paritytech#2088). --------- Signed-off-by: georgepisaltu <george.pisaltu@parity.io> Co-authored-by: joepetrowski <joe@parity.io>
