📝 Walkthrough

Walkthrough

The change modernizes Go syntax and pointer construction across the controller and operator, updates selected JSON serialization tags, replaces manual collection logic, and adds a lint step that verifies go fix produces no changes.

Changes

Go modernization and lint enforcement

Layer / File(s) Summary
Lint enforcement
.github/workflows/lint.yaml
The Go lint job runs go fix ./... in both controller modules and fails if the working tree changes.
API and configuration modernization
controller/api/v1alpha1/*, controller/internal/authorization/basic.go, controller/internal/config/types.go
Pointer creation uses new, lease map copying uses maps.Copy, and selected fields serialize to JSON when empty.
Exporterset modernization
controller/internal/exporterset/*
Exporterset code uses any, new, integer-range loops, and maps.Copy.
Exporterset validation
controller/internal/exporterset/*_test.go, controller/internal/exporterset/provisioners/qemu/*_test.go
Exporterset tests use modern pointer and map types without changing assertions.
Controller and service syntax updates
controller/internal/controller/*, controller/internal/log/*, controller/internal/oidc/*, controller/internal/service/*, controller/internal/metrics/*, controller/cmd/router/*, controller/test/utils/*
Logging and callback types use any. Tests use integer-range loops and WaitGroup.Go. Utilities use strings.SplitSeq.
Operator modernization
controller/deploy/operator/internal/*, controller/deploy/operator/test/*
Operator code uses new, maps.Copy, slices.Contains, any, and integer-range loops.
Dependency alignment
controller/go.mod
k8s.io/utils is recorded as an indirect dependency.

so apparently encoding/json does not actually omit empty structs making this a noop

in 1.24 omitzero was introduced for this https://pkg.go.dev/golang.org/x/tools/go/analysis/passes/modernize#hdr-Analyzer_omitzero

Does this cover controller/deploy/operator/ which has its own go.mod as well? I am worried this could mean interface usages in the sub-module will silently pass the check.

right, added

Runs `go fix ./...` in controller and fails the job if it finds
anything to rewrite, catching outdated API usage without letting CI
silently modify checked-out code.

Signed-off-by: Benny Zlotnik <bzlotnik@redhat.com>
Rewrites flagged by `go fix ./...`: interface{} -> any,
for-range-int loops, maps.Copy for map copies, sync.WaitGroup.Go,
and ptr.To(x) -> new(x). Verified with go build, go vet, and
make test (all pass).
