Explanation
PASS. No security issue was introduced in the reviewed diff. 1. Sensitive data exposure: No new sensitive logging or response serialization. Existing Task logging continues to expose only config names and redacted resource data. 2. Unencrypted secrets: No database models, persistence, or secret storage changes. 3. Authorization bypass: No mutating API endpoints or permission checks changed. 4. Cross-resource access: No child-resource API access changes. 5. TLS/cryptography: No TLS verification, certificate validation, or cryptographic configuration changes. 6. Shared resource safety: Gateway deletion now uses Gateway labels and SSL-only deletion in both providers.
applyStoreChangesremoves the Gateway global rule and removes shared plugin metadata only when no Gateway or IngressClass still references the config (internal/adc/client/client.go:181-219). API7EE schedules a full snapshot after deletion (internal/provider/api7ee/provider.go:230-242). 7. Secret references: No secret-reference resolution changes. The route-parent changes retract stale route configuration and do not grant new access. The PR description is truncated, but the omitted text is not required for these code-based checks.

Full details: E2e Test Quality Review

Explanation
Blocking: the shared-Gateway deletion flow still has no dedicated E2E coverage. The only changed E2E files cover TLS requests, redirects, and pod termination. The existing Gateway deletion test covers one Gateway only (
test/e2e/gatewayapi/httproute.go:825-850). The new shared-resource tests are provider tests usinghttptest, fake clients, and seeded ADC state; they do not delete Kubernetes Gateways and verify the real data plane. The added handlers also callrequire.NoErrorfrom server goroutines (internal/provider/apisix/provider_test.go:180,internal/provider/api7ee/provider_test.go:146), ignore JSON encoding errors, and ignoreserver.Closeerrors.Resolution
Add a dedicated E2E test for each applicable provider mode. Create two Gateways that share one GatewayProxy, configure distinct routes and certificates, delete one Gateway through Kubernetes, and verify through the real data plane that only the deleted Gateway resources disappear while the sibling route and certificate remain. In the added httptest handlers, report request decode failures to the test goroutine instead of calling
requirefrom the server goroutine, check JSON encode errors, and assert server shutdown errors.

Gateway deletion only evicted the Gateway's certificates, so its own global rule and the GatewayProxy's plugin metadata stayed in the shared cache and on the data plane after the last Gateway referencing the proxy was deleted. Evict the Gateway's global rule, and clear the plugin metadata once no Gateway or IngressClass references the proxy.

The API7EE Gateway deletion sync is scoped to SSLs, so the Gateway's evicted global rule and the proxy's plugin metadata stayed on the data plane until the next full sync. Schedule a full sync after the deletion, as the APISIX provider already does.

API7EE defaults sync_period to 0, and Start returned before reading syncCh in that case. Notifications from Gateway deletion and GatewayProxy updates were dropped, so an evicted Gateway's global rule and plugin metadata never reached the data plane. Keep the loop running and only skip the ticker.

Backports apache/apisix-ingress-controller#2905 to the APISIX and API7EE providers.
Gateway API conformance
The investigation started with three skipped HTTPRoute Core tests in the APISIX suite:
HTTPRouteInvalidBackendRefUnknownKindHTTPRouteInvalidCrossNamespaceBackendRefHTTPRouteInvalidNonExistentBackendRefEach requires an invalid backend to produce HTTP 500. Gateway cleanup could delete the translated route, causing 404 instead. This PR restores these tests by fixing the cleanup boundary. The API7EE suite already enables them.
Scope and impact
The controller currently allows multiple Gateway references to one GatewayProxy and merges their resources into one cache. This does not give those Gateways independent routing domains: overlapping hostname/path or SNI rules can still conflict.
HTTPRouteMultipleGatewaysandTLSRouteHostnameIntersectionremain skipped for the shared-data-plane limitations.The reproduced defect is the deletion boundary: removing one Gateway clears entries owned by other Kubernetes resources too, including unrelated, non-conflicting routes and certificates. This PR preserves those entries and reconciles the deleted Gateway's attached routes. It does not add Gateway isolation or resolve conflicting routing rules.
IngressClass deletion is unchanged: it still clears the whole GatewayProxy cache, including resources contributed by Gateways that share it. Narrowing it requires every IngressClass-scoped controller to retract its resources when the IngressClass is deleted, which is out of scope here.
Behavior changes from master
Deleting a Gateway should remove its certificates and trigger reconciliation of its attached routes:
Clearing the entire GatewayProxy cache deletes all of these configurations indiscriminately. The previous full-cache deletion also masked the missing reconciliation of attached routes.
Eventually; redirect headers are checked with one-shot requests.Locationtogether.Each Route controller remembers previously verified parent ownership for the current Route and Gateway identities. This prevents an unknown sibling parent from keeping a deleted Gateway's route active, while allowing surviving known parents to keep serving traffic. Recreated resources and changed class references cannot reuse the old ownership record.
The e2e changes address timing rather than routing semantics. TLS and redirect checks must allow configuration to propagate before failing. Restart setup must wait for old pods to disappear because a terminating pod can still be Ready and receive a port-forward that breaks when it exits.
Validation
Parent-resolution follow-up:
A regression test fails on the previous head in all three cases: deleting a Gateway left its own global rule in the cache, and deleting the last Gateway also left the GatewayProxy's plugin metadata. Both are evicted at the store level; the API7EE immediate sync still covers SSLs alone, because ADC does not label-filter global rules, and a full sync scheduled after the deletion pushes the removals. API7EE defaults
sync_periodto0, which previously madeStartreturn without consuming sync notifications; a zero period now only disables the ticker, so the scheduled sync runs in the default configuration too.Related race tests and the repository-pinned linter pass.
All five Route kinds cover deletion with a never-resolved sibling and preservation of a previously resolved sibling whose GatewayClass disappears.
Provider/controller regression tests fail before the follow-up and pass after it.
Earlier full-suite runs used APISIX 3.19.0 and ADC 0.31.0; CI re-runs against the updated head:
Native API7EE deployment tests were not run locally; they run in CI.
