All code using the result of the generated client-go Informer() (a
cache.SharedIndexInformer) constantly has to do type casts from "any" to the
actual type of the objects managed by the informer.
This is:
- annoying at best
- often done inconsistently (should failed type assertions be logged and if so,
how?)
- a source of bugs (not handling FinalStateUnknown, not handling missing
object, type in event handler not matching the type in the informer)
In contrast, the Lister() result *is* typed. It converts without a type check
in e.g. ResourceIndexer[T].List:
err = cache.ListAllByNamespace(l.indexer, l.namespace, selector, func(m interface{}) {
ret = append(ret, m.(T))
})
This change here does the same wrapping for SharedIndexInformer, Indexer,
index functions and event handler support code. OnDelete is passed
a DeletedObject struct to cover the different scenarios that can occur
when reporting deletion (stale or even nil object!). Extracting key or
name from DeletedObject is guaranteed to never fail because the type-safe
API is restricted to types where the necessary meta data is guaranteed
to be available. This removes another class of tedious error checking.
While not strictly needed, aliases are generated for the generic types because
they are often shorter, easier to type (in particular with auto-complete) and
may help with avoiding an import of k8s.io/client-go/tools/cache.
This is a Go API break because all generated interfaces
change.
Kubernetes-commit: b83b3b39db5eee75af14cdb8d30cfc6899792ec2
The new cadvisor version requires newer golang.org/x modules. Module
version selection raised crypto, mod, net, sync, sys, term, text, and
tools. golang.org/x/net moves from a pseudo-version to the v0.57.0
release, which includes the http2 fixes the pseudo-version pointed at.
cadvisor/lib no longer depends on github.com/gogo/protobuf. This change
removes cadvisor/lib from the gogo/protobuf dependants list in
hack/unwanted-dependencies.json.

detectNumCPU sized nf_conntrack_max using github.com/google/cadvisor/lib
machine topology. nf_conntrack_max is host-wide, so it must be sized from the
node's CPU count, not runtime.NumCPU(): the latter honors the process cpuset
and undercounts when kube-proxy runs under a static CPU policy, which is the
behavior cadvisor worked around (kubernetes/kubernetes#99225).
Use cpuset.NumCPU() from k8s.io/utils, which reads the node's online CPU count
from /sys/devices/system/cpu/online, with a runtime.NumCPU() fallback. This
drops the cadvisor dependency from pkg/proxy/conntrack and bumps k8s.io/utils
to pick up cpuset.NumCPU.
Kubernetes-commit: 92ce184653f03c312915993d7fde93d8e65602c1
Updates golang.org/x/net to v0.55.1-0.20260602153038-42abb857022c to pick up
the go1.27 http2 "wrap" fixes:
- CL 782940 (golang/go#79642): configureServer registers the h2 and http/1.1
ALPN protocols on s.TLSConfig.
- CL 785900 (golang/go#79778): ConfigureTransport/ConfigureTransports enable
HTTP/2 on the transport and keep TLSClientConfig non-nil.
With both, the kube-apiserver secure-serving path and the client-go / apiserver
HTTP/2 clients negotiate HTTP/2 under go1.27 with no Kubernetes-side changes;
no workaround is needed.

Fixes ci-kubernetes-e2e-kind-golang-tip and ci-kubernetes-unit-golang-tip,
which started failing under Go tip identifying as go1.27 with:
vendor/google.golang.org/grpc/internal/transport/handler_server.go:271:18:
undefined: http2.TrailerPrefix
In x/net v0.54.0, TrailerPrefix was defined only in http2/server.go, which
carries `//go:build !(go1.27 && !http2legacy)` and is therefore excluded
under go1.27. Upstream golang/net commit 1efab4271a moved TrailerPrefix
(and other symbols accidentally dropped by the go1.27 server wrapper) into
common files. That fix is released in v0.55.0.

This only changes tests to drop gopkg.in/check.v1, which helps our
dependency tree a little.

Updates k8s.io/kube-openapi across all staging modules and vendors the new
revision. Key changes upstream:
- builder/openapi.go, builder3/openapi.go: use common.EscapeJsonPointer()
when keying definition names into swagger.Definitions / spec.Components.Schemas,
fixing incorrect lookups for types whose names contain JSON-Pointer-reserved
characters (e.g. '/', '~').
- pkg/generators/apidefinitions/loader.go (new): LoadAPIVersion() reads an
apiversion.yaml from a source-tree directory and validates its TypeMeta,
providing a declarative way to describe API versions in-tree.
- pkg/generators/apidefinitions/types.go (new): APIVersion type that carries
the schemeGroupVersion / kindAPIVersion metadata consumed by the loader.
- pkg/generators/config.go, openapi.go, model_names.go: minor generator
improvements accompanying the apidefinitions loader addition.
- pkg/generators/rules/list_type_streaming_tags.go: streaming-tag rule fix.
- pkg/schemaconv/openapi.go, proto_models.go: schema conversion cleanups.
- pkg/validation/validate/result.go: validation result cleanup.
