fix: retract route configuration when no parent accepts the route (backport apache/apisix-ingress-controller#2858) - #476
Conversation
Backports apache/apisix-ingress-controller#2858. #471 covered the exit where ParseRouteParentRefs resolves no Gateway of ours. The neighbouring one is still open: the parentRef does resolve to one of our Gateways, but no listener accepts the route, so isRouteAccepted is false and the update is skipped with no matching delete. Narrowing a listener's allowedRoutes, removing the listener a sectionName points at, or editing hostnames until they no longer intersect all reach it. The route reports Accepted=False while the old data plane route keeps forwarding, and deleting the route object is the only way to clear it, which is the wrong remedy when the edit was meant to revoke a tenant's access without touching their objects. Retract on that path in all five reconcilers, and set TypeMeta first for the same reason #471 does: Provider.Delete derives the resource labels from the object Kind. recordingProvider gains an updated counter and recordingUpdater is added beside it, so a test can assert that a route is not published rather than only that it is deleted.

An HTTPRoute can carry a RequestHeaderModifier that sets Authorization, so logging the object writes its header values into the controller log, which is usually read by a wider audience than the API. The retraction paths copied the shape of the NotFound branch above them; the delete paths in the ApisixPluginConfig and servicePort backports already log utils.NamespacedName, so this also makes the five consistent with those. Only the lines this change introduces are touched.
What this PR does / why we need it:
Backports apache/apisix-ingress-controller#2858.
#471 covered the exit where
ParseRouteParentRefsresolves no Gateway of ours. The neighbouring one in the same function is still open: the parentRef does resolve to one of our Gateways, but no listener accepts the route.Three ordinary edits reach it and leave a live route behind:
allowedRoutesso the route is no longer admitted (NotAllowedByListeners)sectionNamepoints at (NoMatchingParent)hostnamesuntil they no longer intersect the listener (NoMatchingListenerHostname)In each case the route reports
Accepted=Falsewhile the data plane keeps forwarding the configuration an earlier reconcile published. Deleting the route object is the only way to clear it, which is the wrong remedy when the point of the edit was to revoke a tenant's access without touching their objects.TypeMetais set beforeProvider.Deletefor the same reason #471 does it:Deletederives the resource labels from the object Kind.Differences from upstream
Applied as the branch's net diff rather than commit by commit. Upstream's first revision also patched the empty-parent exit and its second revision reverted that once #2834 took it over; this tree already has #2834 via #471, so only the surviving hunk applies.
recordingProviderinhttproute_controller_test.go, added by #471, gains anupdatedcounter, andrecordingUpdateris added beside it. The unit test needs both to assert that a route is not published, rather than only that it is deleted.This overlaps with #472, which cherry-picked the upstream
apisixconsumer_controller_test.gobefore #471 landed and therefore declares a secondrecordingProviderin the same package. That has to be resolved wherever it merges second; I will update #472 to reuse the one on master.Tests
internal/controller/httproute_controller_retract_test.gocovers the not-accepted path, the accepted path, and provider-error propagation.test/e2e/gatewayapi/httproute.goadds an end-to-end spec: a listener that starts out admitting HTTPRoute is narrowed to GRPCRoute only, the route object is never touched, and the spec asserts the route reportsNotAllowedByListeners, that the request then 404s, and that restoring the listener brings it back, so the retraction is not one-way.allowedRoutes.kindsis used rather than the namespace selector from the report because both reach the samerouteMatchesListenerAllowedRoutesgate and the scaffold runs everything in one namespace.Summary by CodeRabbit
