fix: release concurrency system only consumes tokens when releasings are executed successfully #1883
Conversation
…are executed successfully
|
WalkthroughThis pull request updates the debugging configuration and modifies the concurrency handling in the RunEngine. The changes include updating the test command in the VSCode launch configuration, altering asynchronous functions to return explicit boolean results, and adjusting the executor behavior for the token bucket queue. Additionally, new tests have been added to verify that tokens are correctly managed when the executor returns false. Changes

127-127: Logging at info level may be verbose.
Switching from debug to info could cause log noise if concurrency is high. Evaluate whether debug would be more appropriate for frequent events.- this.logger.info("Consumed token in attemptToRelease", { + this.logger.debug("Consumed token in attemptToRelease", {
291-291: Elevating log level to info.
Logging executor calls at info may be desired for auditing, but be mindful of excessive log volume.- this.logger.info("Calling executor for release", { releaseQueueDescriptor, releaserId }); + this.logger.debug("Calling executor for release", { releaseQueueDescriptor, releaserId });
434-563: NewgetQueueMetricsmethod implementation.
This scanning approach is functional and provides thorough metrics collection. However, scanning large sets of queues may impact performance.Consider implementing batching or caching strategies if a significant number of queues exist, or if performance overhead becomes noticeable.

11-11: Increase in test environment retries looks good.
RaisingmaxRetriesPerRequestto 5 for the Vitest environment helps mitigate transient errors during tests. This should improve reliability without notably impacting overall performance.internal-packages/run-engine/src/engine/tests/releaseConcurrencyTokenBucketQueue.test.ts (6)
23-23: Executor return alignment is correct.
Returningtruehere aligns with the new executor contract that expects a boolean.
225-225: Consistent boolean return on successful execution.
Returningtruewhen the executor finally succeeds is now consistent with the modified interface.
304-304: Accurate success signal.
Includingreturn true;ensures the concurrency engine interprets this as a successful run, matching the updated behavior.
425-425: Proper token handling acknowledgment.
Returningtruenotifies the system that the run has succeeded and frees the token.
523-577: Well-structured test for handling 'false' executor return.
This new test comprehensively verifies that afalsereturn leads to the token being returned without requeuing. It nicely covers the scenario of immediately making the token available for the next run.
683-715: Thorough metrics retrieval test.
These lines effectively test the newly introducedgetQueueMetricsfeature by verifying queue lengths and token counts. Coverage appears robust for multiple queues and states.internal-packages/run-engine/src/engine/releaseConcurrencyTokenBucketQueue.ts (10)
2-2: Tracing import.
ImportingstartSpanandTracerallows for improved observability. No concerns here.
5-5: UsingsetIntervalfromnode:timers/promises.
This is a modern, clean approach for running tasks on a schedule.
6-6: Flattening attributes.
Pulling inflattenAttributesis straightforward; no obvious downsides.
19-22: Executor now returns a boolean.
Documenting the new return expectations is good practice, clarifying the meaning offalsevs.true.
85-85: Initiating metrics producer by default.
Starting the metrics producer when consumers are enabled is a sensible default.
278-278: Switching toPromise.allSettled.
UsingPromise.allSettledensures all processing completes even if one operation fails. This is safer for batch operations.
293-297: Handling successful executor runs explicitly.
The distinction between success (released) and failure fosters clarity.
298-302: Properly logging non-releasing outcomes.
Provides transparent feedback when the executor signals it should not consume concurrency.
303-312: Immediate token return onfalse.
This logic correctly returns the token without retry, aligning with the new executor contract.
402-424: Metrics producer routine.
The new routine to periodically log queue metrics is well-structured. Consider potential performance overhead if the queue grows large.
