vcmd/protoc-gen-go-grpc/v1.4.0: protoc-gen-go-grpc v1.4.0

Compare Source

New Features

• Add an optional implementation of streams using generics (Experimental) (#​7057)
  • The new use_generic_stream_experimental=true option will cause the gRPC codegen to use prebuilt generic types to implement client and server stream objects, rather than generating new types and implementations for every RPC method. We intend to transition this to the default behavior in the next release. Please test it and provide any feedback.

Notable changes

New Features
Protobuf editions are fully supported. You can now use edition = "2023" in .proto files together with the proto-gen-go. Edition2023 does not introduce any new features but can be used to replace syntax "proto2/3". Future editions might introduce new features. See https://protobuf.dev/editions/overview/ for more details on protobuf editions.

Documentation
Various smaller changes to improve existing documentation and to add more examples.

• CL/574455: proto: extend Marshal documentation, include an example
• CL/574635: proto: extend Unmarshal documentation, include an example
• CL/574836: protogen: update Options documentation.
• CL/573361: proto: add examples for Size, MarshalAppend (regarding allocations)
• CL/579895: encoding/{protojson,prototext}: strengthen wording on stability

Extensions
These are mostly performance improvements or preparations for performance improvements.

• CL/575035: internal/impl: ensure proto.HasExtension does not allocate
• CL/576315: [encoding/{protojson,prototext}: strengthen wording on stability](proto: CSE ProtoReflect() and TypeDescriptor() in proto.HasExtension
• CL/576316: internal/impl: pass ExtensionTypeDescriptor to extensionMap
• CL/579275: [proto] use the correct parent when resolving features for extensions
• CL/579595: proto: return an error instead of producing invalid wire format

v1.33.0

Compare Source

This release contains one security fix:

• encoding/protojson: Unmarshal could enter an infinite loop when unmarshaling certain forms of invalid JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any value, or when the UnmarshalOptions.DiscardUnknown option is set. Unmarshal now correctly returns an error when handling these inputs. This is CVE-2024-24786.
