The mechanical migration (9b8e9a14b) left the tree uncompilable: it used
luxfi/metric as a prometheus drop-in, but several symbols were missing and a
few types were misused. Finish it against luxfi/metric v1.8.2 (which adds the
prometheus-compat surface):
- pin luxfi/metric v1.8.2 (native-histogram HistogramOpts fields, package
MustRegister/Unregister, AlreadyRegisteredError, With/AutoFactory,
GoCollectorOption/MetricsAll, Vec.Delete, no-op collector registration)
- use metric.Registry / metric.{Histogram,Counter}Vec as INTERFACES, not
concrete pointers (plugin/metrics, plugin/kubernetes)
- build with -tags metrics so luxfi/metric's collecting registry is active
(the default is a //go:build metrics no-op stub); wire it into Makefile
GOTAGS, the GHCR image build, and the CI test matrix
- test harness: select a metric-name validation scheme for the exposition
parser (client_golang used to set the global default; CoreDNS no longer
imports it)
go build ./... + go test -tags metrics ./plugin/metrics/... /kubernetes /reload
are green.
