Breaking Change: The protovalidate.ValidationError type is no longer a protobuf buf.validate.Violations message alias, but a struct containing a slice of protovalidate.Violation instances. In most cases, accessing the Proto member of the violation is all that needs to be done:

     for _, violation := range err.Violations {
-        fmt.Println(violation.GetMessage())
+        fmt.Println(violation.Proto.GetMessage())
     }

protovalidate.ValidationError still has a ToProto() method that returns the protobuf buf.validate.Violations message equivalent.

---

The new protovalidate.Violation structure contains additional in-memory information about the violation which cannot be serialized to the wire:

• FieldValue: A protoreflect.Value containing the value of the field failing validation, if there is a field corresponding to the violation.
• FieldDescriptor: A protoreflect.FieldDescriptor corresponding to the field failing validation.
• RuleValue: A protoreflect.Value containing the value of the rule failing validation, if there is a rule corresponding to the violation.
• RuleDescriptor: A protoreflect.FieldDescriptor corresponding to the rule failing validation.

Take, for example, the following protobuf message schema:

message User {
    string email = 1 [(buf.validate.field).string.email = true];
}

If you try to validate the struct pb.User{Email: "invalid"}, the FieldValue will be "invalid" and the RuleValue will be true.

Some violations do not correspond directly to a field, such as a message constraint failure; in these cases, the FieldValue will be an invalid value and the FieldDescriptor will be nil.

• Bump the go group with 2 updates by @​dependabot in https://github.com/bufbuild/protovalidate-go/pull/161

Known Issues

• The recently added grpc.NewClient function is incompatible with forward proxies, because it resolves the target hostname on the client instead of passing the hostname to the proxy. A fix is expected to be a part of grpc-go v1.70. (#​7556)

New Features

• stats/opentelemetry: Introduce new APIs to enable OpenTelemetry instrumentation for metrics on servers and clients (#​7874)
• xdsclient: add support to fallback to lower priority servers when higher priority ones are down (#​7701)
• dns: Add support for link local IPv6 addresses (#​7889)
• The new experimental pickfirst LB policy (disabled by default) supports Happy Eyeballs, interleaving IPv4 and IPv6 address as described in RFC-8305 section 4, to attempt connections to multiple backends concurrently. The experimental pickfirst policy can be enabled by setting the environment variable GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST to true. (#​7725, #​7742)
• balancer/pickfirst: Emit metrics from the pick_first load balancing policy (#​7839)
• grpc: export MethodHandler, which is the type of an already-exported field in MethodDesc (#​7796)
  • Special Thanks: @​mohdjishin

Bug Fixes

• credentials/google: set scope for application default credentials (#​7887)
  • Special Thanks: @​halvards
• xds: fix edge-case issues where some clients or servers would not initialize correctly or would not receive errors when resources are invalid or unavailable if another channel or server with the same target was already in use . (#​7851, #​7853)
• examples: fix the debugging example, which was broken by a recent change (#​7833)

Behavior Changes

• client: update retry attempt backoff to apply jitter per updates to gRFC A6. (#​7869)
  • Special Thanks: @​isgj
• balancer/weightedroundrobin: use the pick_first LB policy to manage connections (#​7826)

API Changes

• balancer: An internal method is added to the balancer.SubConn interface to force implementors to embed a delegate implementation. This requirement is present in the interface documentation, but wasn't enforced earlier. (#​7840)

Performance Improvements

• mem: implement a ReadAll() method for more efficient io.Reader consumption (#​7653)
  • Special Thanks: @​ash2k
• mem: use slice capacity instead of length to determine whether to pool buffers or directly allocate them (#​7702)
  • Special Thanks: @​PapaCharlie

Documentation

• examples/csm_observability: Add xDS Credentials and switch server to be xDS enabled (#​7875)
