[JSON RPC API] - New APIs for getting object's dynamic field #5882

patrickkuo · 2022-11-05T15:12:39Z

Summary

This PR adds dynamic field support to Sui's JSON-RPC APIs.

Notable changes

added dynamic_field_index and owner_index to IndexStore storing all object owned dynamic field object info
owner_index in AuthorityPerpetualTables is deprecated and will be removed in subsequence PR
new get_dynamic_field_object method for retrieving object using parent object id and dynamic field name.

Examples

the first object is nfts::marketplace::Marketplace, second object is nfts::geniteam::Player

In https://docs.sui.io/devnet/build/programming-with-objects/ch5-dynamic-fields, we use dynamic field and dynamic object field to refer to two different types of dynamic fields and mentioned that an object stored in this kind of field will be considered wrapped and will not be accessible via its ID by external tools (explorers, wallets, etc) accessing storage.. Does this endpoint support both types?

yes both are supported.

One question I have is do we still support object owning objects in Move? i.e. transferring ownership to an object without using dynamic field. This PR assumes an object can only own another object using DF, is this the right assumption? @tnowacki ?

ronny-mysten

Noted a few things in what I believe is the output to documentation. Ignore me if I'm wrong.

I'm thinking we should move owner indexer and the new dynamic field tables into indexes.rs.

It does not seem the owner info has to be in the critical path, or even live in validator's storage. After some quick look, the only place that validators may look at the owner table is make_account_info which will be called by handle_account_info_request. Today the only callsite is get_all_owned_objects and sync_all_owned_objects, which iiuc, is now deprecated with gateway gone. @lxfind wdyt?

The long term plan is to move all indices to indexer. cc @mystenmark

I think we will still need owner_index for make_account_info, however dynamic_field_index should definitely move to the index storage.

I will make that changes.

lxfind · 2022-11-30T18:25:35Z

Correct. owner_index should not belong to validator store.

Correct. Within Move, you can only make an object own another object through dynamic fields (in particular dynamic object fields)

Iiuc, make_account_info is obsolete after gateway deprecation

Still going through things! But wanted to leave the first set of comments I had so far (I will continue to look more later today)

You probably want to filter for the type here too. I don't think you want this event/index for the secondary object in the dynamic object field case.

In other words, we need to check that the object's type is sui::dynamic_field::Field, otherwise it could be some other object being used with sui::dynamic_object_field

Still reviewing but leaving these comments here as I go: Do we need a type filter here if we are filtering on creation?

good catch! this will remove unnecessary seek and delete ops on db

Actually after looking at the code (this was done quite a while ago 😅), it will require an extra DB read to retrieve the object type because TransactionEffects only contains ObjectRef, which will be more expensive because it will deserialise the whole Object from storage. We could do this without the db read after this PR which adds ObjectType to the effects.

I will add a TODO for now.

I'm just learning here, when does index_tx get run? This is some separate service or something right?

Currently this runs in fullnode (@gegaowp 's indexer work will probably move this to the indexer), there are 2 code path leading to this method, one is from the node_sync when the fullnode receive new transactions; another path is from the TransactiondOrchestrator which updates the local store after successful tx execution.

Not important, but I've been noticing on my PRs too, it doesn't seem like rustfmt likes let-else. There isn't a space in else{

Just noting and summoning my normal person for Rust questions, @bmwill. Do we need to do something else to configure rustfmt to handle let-else?

Nope, unfortunately the let-else feature was stabilized without the corresponding formatting being added to rustfmt
