refactor(codec/unknownproto): use official descriptorpb types, do not rely on gogo code gen types. #18541

testinginprod · 2023-11-22T14:10:50Z

Description

This PR removes de gogo-proto-gen dependency from unknown proto and uses the official descriptor APIs living google.golang.org/protobuf.

This is a required step for a sub-sequent PR which will enable the usage of google.Protobuf.Anys in Txs without them being registered in the interface registry.

Walkthrough

The changes involve refactoring the codec/unknownproto module to replace the usage of gogo protobuf descriptor types with the official descriptorpb package types from Google's protobuf library. This includes updating import statements, function signatures, and type references throughout the code to align with the descriptorpb types, as well as adding new utility functions to handle wire type conversions and scalar type checks.

Changes

File Path	Change Summary
`codec/unknownproto/unknown_fields.go`	Replaced `gogo` descriptor imports with `descriptorpb`, updated types and function signatures, added new utility functions.
`CHANGELOG.md`	Documented the introduction of `descriptorpb` types for unknown proto handling and other changes.

Assessment against linked issues

Objective	Addressed	Explanation
Refactor `codec/unknownproto` to not rely on `gogo` descriptor internals (#18540)	✅	The changes replace `gogo` types with `descriptorpb` types, which aligns with the objective of the issue.

Related issues (Beta)

#18541: This PR seems to be part of the work mentioned in the changelog and the code changes, addressing the use of descriptorpb types for unknown proto handling.

10-19: The import of github.com/cosmos/gogoproto/proto should be removed if it is no longer used after the refactoring to use descriptorpb types.

100-113: The comment on lines 111-113 references github.com/cosmos/gogoproto, which may no longer be relevant if the dependency on gogo protobuf has been removed. Verify if this comment needs updating or removal.

198-257: The checks array has been updated to use descriptorpb.FieldDescriptorProto_Type. Ensure that all references to checks throughout the codebase are updated to use the correct index type (int instead of protowire.Type).

260-265: The canEncodeType function signature has been updated to use int for wireType. Ensure that all calls to this function are updated accordingly.

364-370: The extractFileDescMessageDesc function is using protov2.Unmarshal which is correct as per the refactor. However, ensure that the protoBlob is correctly formatted for descriptorpb.FileDescriptorProto before unmarshalling.

381-384: The descriptorMatch struct has been updated to use descriptorpb.FieldDescriptorProto. Ensure that all usages of descriptorMatch are consistent with this change.

440-483: The findWireTypeFromFieldDescriptorProtoType function should be reviewed to ensure that it returns the correct protowire.Type for each descriptorpb.FieldDescriptorProto_Type. This is critical as the function is used to determine the expected wire type for a given field descriptor type.

486-509: The isScalar function checks if a field is a scalar type. Ensure that the function's logic is still correct after the refactor and that it aligns with the updated descriptorpb.FieldDescriptorProto_Type values.

101-114: The comment on lines 112-113 seems to be outdated and should be updated or removed if it no longer applies to the current implementation.

199-258: The checks array is a good optimization for constant time lookups. Ensure that all wire types and descriptor types are correctly mapped and that no types are missing.

365-371: Ensure that the error from gzip.NewReader and io.ReadAll are handled properly and that the resources are closed appropriately to avoid resource leaks.

380-385: The descriptorMatch struct is used for caching, ensure that the cache is properly synchronized to prevent data races.

407-413: > Note: This review was outside of the patch, so it was mapped to the patch with the greatest overlap. Original lines [392-413]

When caching descriptor information in descprotoCache, ensure that the cache is invalidated or updated when descriptors change to prevent stale data issues.

487-510: The isScalar function correctly identifies scalar types. Ensure that this function is used consistently throughout the codebase to determine scalar types.

The error struct errMismatchedWireType should include the expected and actual wire types using descriptorpb.FieldDescriptorProto_Type instead of protowire.Type to align with the refactor.

Thank you for this change @testinginprod. I've added some comments. Although what's the rationale behind this change? Is it to get rid of the protogen-gogo-descriptor package? If it is, I believe we forked an entire repository for which it'll still exist. Thank you

testinginprod · 2023-11-29T10:35:59Z

@odeke-em thank you for the review.

This is a preliminary step PR to make a more significant change to unknownproto, specifically unknonwproto currently does not allow google.Protobuf.Any to be passed into a TX unless they've been registered in interface registry.

This is not desirable for two reasons:

there's a use-case for having non-interface used google.Protobuf.Anys in the TX body.
we have the first use case for the x/accounts module.
this is also the default behaviour implemented by x/tx which is meant to replace codec/unknownproto: https://github.com/cosmos/cosmos-sdk/blob/main/x/tx/decode/unknown.go (note: we want to have this in the legacy baseapp, x/tx will be used by the new serverv2).

Alongside enabling support for having non-interface-registry anys in TXs, we want to also be able to decode anys which have a protov2 counterparty but not a gogoproto one. Using default descriptorpb types makes this transition a lot more effortless otherwise we'd be forced to convert from gogo-protoc-gen.Descriptor into descriptorp.Descriptor .

12-20: The import changes align with the summary and the refactoring goal of using descriptorpb types from the official protobuf library.

69-72: The update to use fieldTypeToProtowireType for determining WantWireType is consistent with the refactoring goal and should ensure correct wire type matching.

104-104: The update to use isScalar for checking if a field is scalar aligns with the refactoring goal and the summary.

199-266: The refactoring of checks to use descriptorpb.FieldDescriptorProto_Type is consistent with the goal of using descriptorpb types.

333-335: The update of the global variable protoFileToDesc to use descriptorpb.FileDescriptorProto is consistent with the refactoring goal.

393-396: The update of the getDescriptorInfo function signature to use descriptorpb types is consistent with the refactoring goal.

441-442: The DefaultAnyResolver.Resolve function signature appears unchanged, which seems to be a no-op. Please verify if this was intentional or if changes were expected but not made.

445-504: The addition of the fieldTypeToProtowireType and isScalar functions is consistent with the refactoring goal and the summary.

480-481: The citation for the isScalar function is correctly included, addressing the previous review comment.
