1-368: Overall assessment: Changes effectively implement E3 request completion tracking.The modifications to this test file are focused and effective:
- They introduce the
E3RequestCompleteevent, aligning with the PR objectives.- The changes are minimal, affecting only the necessary parts of the
test_public_key_aggregation_and_decryptiontest.- Other test cases in the file remain unaffected, maintaining the integrity of the existing test suite.
These changes enhance the test coverage by verifying the proper handling of E3 request completion, which is crucial for the actor destruction mechanism described in the PR objectives.
Suggestion for future improvement:
Consider adding a specific test case that verifies the behavior of the system after theE3RequestCompleteevent is triggered, to ensure that actors are properly destroyed or deregistered.packages/ciphernode/router/src/e3_request_router.rs (2)
87-87: Add documentation for the newcompletedfieldConsider adding a comment to explain the purpose of the
completedfield in theE3RequestRouterstruct. This will improve code readability and maintainability.
127-139: Simplify the creation and sending ofE3RequestCompleteeventYou can make the code more concise by inlining the event creation and sending.
Apply this diff to simplify the code:
EnclaveEvent::PlaintextAggregated { .. } => { - // Here we are determining that by receiving the PlaintextAggregated event our request is - // complete and we can notify everyone. This might change as we consider other factors - // when determining if the request is complete - let bus = self.bus.clone(); - let event = EnclaveEvent::from(E3RequestComplete { - e3_id: e3_id.clone(), - }); - // Send to bus so all other actors can react to a request being complete. - bus.do_send(event); + // Notify all actors that the request is complete + self.bus.do_send(EnclaveEvent::from(E3RequestComplete { + e3_id: e3_id.clone(), + })); }packages/ciphernode/aggregator/src/plaintext_aggregator.rs (1)
114-114: Add logging for unhandledEnclaveEventsCurrently, unhandled
EnclaveEvents are ignored silently. Adding a log statement in the default case can assist in debugging unexpected events.Apply this diff to add logging:
- _ => (), + _ => { + println!("Unhandled EnclaveEvent: {:?}", msg); + },packages/ciphernode/aggregator/src/publickey_aggregator.rs (1)
227-228: Consider Adding Logging for Actor TerminationAdding a log statement before calling
ctx.stop()can aid in monitoring the actor's lifecycle and facilitate debugging.Apply this refinement:
fn handle(&mut self, _: Die, ctx: &mut Self::Context) -> Self::Result { + println!("PublicKeyAggregator actor is stopping."); // Consider using a proper logging framework ctx.stop() }

packages/ciphernode/tests/tests/test_aggregation_and_decryption.rs (3)
4-5: LGTM: Import statement updated correctly.The addition of
E3RequestCompleteto the import list is consistent with the PR objectives and the introduction of the new event type for handling E3 request completion.
226-226: LGTM: Test assertion updated correctly.The assertion for the event history length has been properly updated from 5 to 6, reflecting the addition of the new
E3RequestCompleteevent. This change ensures that the test correctly verifies the presence of all expected events, including the new one.
251-254: LGTM: New event added to history assertion.The
E3RequestCompleteevent has been correctly added to the expected event history. This addition:
- Aligns with the PR objectives of implementing mechanisms for actor destruction.
- Maintains consistency by including the correct
e3_idparameter.- Is logically placed at the end of the history, signifying the completion of the E3 request process.
This change enhances the test coverage by ensuring that the E3 request completion is properly tracked and verified.
packages/ciphernode/core/src/events.rs (5)
119-122: LGTM: New event type aligns with PR objectiveThe addition of
E3RequestCompleteto theEnclaveEventenum is well-structured and consistent with other variants. This new event type directly supports the PR's objective of addressing lingering actors associated with past e3 requests, allowing for proper destruction of these actors once they have finished their tasks.
149-149: LGTM: Correct classification of E3RequestComplete as local-onlyThe addition of
E3RequestCompleteto theis_local_onlymethod is correct. Marking this event as local-only is appropriate because it represents an internal state change that doesn't need to be propagated to other nodes in the network. This classification helps optimize network communication by preventing unnecessary event broadcasting.
168-168: LGTM: Consistent implementation for E3RequestCompleteThe addition of
E3RequestCompleteto theFrom<EnclaveEvent> for EventIdimplementation is correct and consistent with other event types. This ensures thatE3RequestCompleteevents can be properly converted toEventId, maintaining the integrity of the event system.
247-254: LGTM: Consistent From implementation for E3RequestCompleteThe implementation of
From<E3RequestComplete> for EnclaveEventis correct and follows the established pattern for other event types. It properly generates anEventIdfrom the data and includes both the id and data in the resultingEnclaveEvent. This consistency ensures thatE3RequestCompleteevents can be seamlessly integrated into the existing event system.
367-372: LGTM for E3RequestComplete, clarification needed for Die messageThe
E3RequestCompletestruct is well-defined and consistent with other event structs. The comment indicating it's a local-only event is helpful and aligns with its implementation inis_local_only.However, the
Diemessage is a new addition not mentioned in the PR summary or objectives. While it likely relates to the goal of destroying actors, its specific purpose and usage are not clear from this context.Could you please clarify the intended use of the
Diemessage? How does it fit into the actor destruction process described in the PR objectives?To help understand its usage, let's search for its occurrences in the codebase:
Also applies to: 397-399
✅ Verification successful
Verified usage of the Die message
The
Diemessage is correctly implemented across the codebase to terminate actor contexts as intended. Its usage aligns with the objective of destroying actors, and no further clarification is needed.🏁 Scripts executed

packages/ciphernode/keyshare/src/keyshare.rs (3)
5-5: ImportingDieevent for actor terminationThe addition of
Dieto the imports allows theKeyshareactor to handle termination events appropriately.
38-40: HandlingE3RequestCompleteto initiate actor shutdownBy matching
EnclaveEvent::E3RequestCompleteand notifyingDie, the actor initiates a graceful termination after completing its tasks, aligning with the objective to prevent unnecessary resource consumption.
103-108: ImplementingDiehandler to stop the actorThe
Diehandler correctly callsctx.stop(), ensuring theKeyshareactor terminates gracefully upon receiving aDiemessage.packages/ciphernode/aggregator/src/plaintext_aggregator.rs (2)
4-5: Imports updated for new message handlingThe addition of
DieandE3RequestCompleteto the imports is appropriate for handling the new message types introduced.
111-114: Refactored event handling improves extensibilitySwitching from an
if letto amatchstatement forEnclaveEventhandling enhances code readability and makes it easier to extend with additional event types in the future.packages/ciphernode/aggregator/src/publickey_aggregator.rs (4)
4-4: ImportDiefor Actor TerminationThe addition of
Dieto the import list is necessary for the new termination logic and aligns with the PR objectives.
119-122: RefactorhandleMethod withmatchStatement for Enhanced ExtensibilityRefactoring the
handlemethod to use amatchstatement improves code readability and allows for handling multipleEnclaveEventvariants efficiently. This change enhances the extensibility of the event handling mechanism.
121-121: HandleE3RequestCompleteEvent to Trigger Actor TerminationBy notifying
Dieupon receivingEnclaveEvent::E3RequestComplete, the actor is instructed to terminate gracefully after completing its task. This implementation effectively prevents lingering actors and aligns with the goal to mitigate memory leaks.
225-230: ImplementHandler<Die>to Gracefully Stop the ActorAdding the
Handler<Die>implementation forPublicKeyAggregatorallows the actor to stop its context when aDiemessage is received. This ensures proper cleanup and resource management, fulfilling the requirement to destroy actors after their tasks are complete.
Closes: #135
This ensures that actors for past e3 requests don't hang around after they have finished processing the requests.
E3RequestRouterdetermines when an E3Request is completed and cleans up its references.Relevant actors listen for E3RequestComplete event and then commit seppuku
Considered a few other designs like having actors termination trigger router clean up but they were too complex and this was the simplest and cleanest way to do this which keeps things ready for future management.
