There was a problem hiding this comment.
This means we will regenerate nginx config every time a ReferenceGrant is created, updated (generation must change), or deleted, even if it does not apply to the accepted Gateway.
do we need to track these things somewhere? so that we know about them when the time comes to reduce number of reloads.
We have this issue which I think covers it: #552 |

Proposed changes
Problem: NKG does not support cross-namespace Secret references on Gateway.
Solution: Add support for ReferenceGrants that permit Gateways to reference Secrets in different namespaces. NKG now processes ReferenceGrants and verifies that Gateways with references to Secrets in different Namespaces have a corresponding ReferenceGrant. If no ReferenceGrant exists, the
RefNotPermittedreason is used in all the listener conditions (Accepted, Programmed, and ResolvedRefs), and the listener is marked invalid. Secrets will only be resolved if the reference is permitted. No additional validation is needed for ReferenceGrant as it does not correspond to any nginx config. We treat every upsert/delete of a ReferenceGrant as a change. This means we will regenerate nginx config every time a ReferenceGrant is created, updated (generation must change), or deleted, even if it does not apply to the accepted Gateway.Testing: 100% unit test coverage of new functions, updated existing unit tests, and verified that the applicable conformance test pass.
Closes #694
