Upgrading Google Cloud Client Libraries in Config Connector
This skill outlines the process for updating Google Cloud client libraries (e.g., cloud.google.com/go/alloydb or cloud.google.com/go/spanner) in Config Connector (KCC).
Workflow
1. Identify the Latest Version
Find the latest version of the target Go client library. You can run:
go list -m -versions cloud.google.com/go/<service>
2. Update the Root Module
Update the dependency in the root go.mod directory to the target version and tidy up.
go get cloud.google.com/go/<service>@<version>
go mod tidy
3. Update the MockGCP Module
Update the dependency in the mockgcp/go.mod directory to align version configuration and tidy up.
cd mockgcp
go get cloud.google.com/go/<service>@<version>
go mod tidy
cd ..
4. Verify Fuzzing & Identify Missing Fields
Run KRM mapping fuzz tests to ensure the updated types do not introduce serialization or validation regressions.
go test -v ./pkg/fuzztesting/fuzztests/
If any new fields are introduced in the updated library, the roundtrip verification might fail. The failure messages will output helpful recommendations such as:
Add f.Unimplemented_NotYetTriaged(".new_field") to the fuzzer for the proto type <proto_type> to mark this field as not yet triaged.
5. Mark New Fields as Untriaged
Locate the corresponding fuzzer file for the service (typically under pkg/controller/direct/<service>/<kind>_fuzzer.go).
Add the recommended field ignore using f.Unimplemented_NotYetTriaged(".new_field") in the initialization of the fuzzer.
6. Format and Validate
Run formatting and verify the entire package compiled without static analysis issues:
make fmt
go vet ./pkg/controller/direct/<service>/... ./pkg/fuzztesting/fuzztests/...
Run the fuzz tests again to ensure all tests pass:
go test -v ./pkg/fuzztesting/fuzztests/
