🟡 Changes recommended
The current name truncation path can yield a blank event name after stripping separators, which can make recording fail instead of safely falling back to the default identity-hash name.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
Adds configurability to the DefaultEventRecorder to better control event aggregation identity, ownership metadata, and naming, addressing the limitations described in #3601 and providing an end-to-end integration test demonstrating the configuration.
Changes:
- Introduces recorder-level strategies for default aggregation keys (
EventKeyStrategy) and event naming (EventNamingStrategy), plus per-record overrides viaEventRecord. - Adds optional owner reference support (recorder default with per-record tri-state override) to relate events to their “regarding” object when UID is available.
- Expands unit/integration tests to cover deterministic naming, aggregation behavior, naming strategy behavior, and owner reference behavior.

- Around line 94-95: Update the event assertion in the ConfiguredEventRecorderIT
test to validate the latest aggregated message using the current event count,
rather than accepting any message with the expected prefix via startsWith.
Account for one aggregated event per reconciliation and lifecycle runs beyond
two reconciliations.

229-235: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAssert name stability instead of the exact digest.
This test pins the literal digest
test1.3c699548f37ff9cd6d2a786f64a27228. The value depends on the whole identity string layout: kind, uid, type, reason, reporting component, message, the NUL separator, and SHA-256. Any intended change to that layout fails this test with no useful diagnostic. The name shape is already covered bynamesEventsWithADnsSafeHashSuffixat Line 238.The stated intent is stability for the same event. Record the same event twice and compare the two names.
♻️ Proposed refactor
`@Test` void alwaysDerivesTheSameDefaultNameForTheSameEvent() { - recorder.record(EventRecord.normal("Created", "created"), context(configMap())); - - assertThat(emitted.get(0).getMetadata().getName()) - .isEqualTo("test1.3c699548f37ff9cd6d2a786f64a27228"); + recorder.record(EventRecord.normal("Created", "created"), context(configMap())); + recorder.record(EventRecord.normal("Created", "created"), context(configMap())); + + assertThat(emitted.get(0).getMetadata().getName()) + .isEqualTo(emitted.get(1).getMetadata().getName()); }🤖 Prompt for AI Agents

thank you @afalhambra-hivemq ! |
The commits are self-contained, so feel free to review or cherry-pick them separately.
EventKeyStrategyand aDefaultEventRecorder.builder(sink)with akeyStrategy(...)option. WithbyReason()the message drops out of the event identity, so status-style events aggregate onto one event (count grows, message gets replaced) withoutkey()boilerplate at every call site. A per-recordkey()still wins, andnone()is today's behavior.ownerReference(true)on the builder, with a per-record override viaEventRecord.Builder.ownedByRegarding(boolean). Only set when the object already has a uid.EventRecord.Builder.name(String)and a recorder-levelEventNamingStrategy. Precedence: record name, then strategy, then the identity hash. The name is the aggregation identity and must be a valid RFC 1123 DNS subdomain (the javadoc has the details), long names get truncated at 253 chars, and blank means unset.Fixes #3601
