Complete scheduler and WebSocket lifecycle cleanup

[binaryfire]

Summary

Deferred functions registered by scheduled tasks and WebSocket callbacks were never run by their owning lifecycle. WebSocket handshakes also ran route middleware without calling its termination methods. This completes that cleanup and fixes Reverb treating coroutine cancellation as a protocol error or continuing delivery after cancellation.

It also fixes a channel cleanup failure: if leaving one Reverb channel threw, later channels could retain a closed connection indefinitely.

Changes

Scheduled tasks

Run deferred functions once after each task and its lifecycle listeners. Nested Artisan calls leave that work to the task boundary. Ordinary deferred functions run after success; always() functions also run after ordinary failures. Cancellation skips remaining deferred work and preserves mutex cleanup.

Keep handled failure state local to the task coroutine. Give paused-task skip listeners their own finite execution scope, and send background-finished notifications only for tasks that were not skipped because of overlap or another server.

Scheduled commands continue to run inside the scheduler process. The documentation explains when to use Schedule::exec('php artisan ...') for commands that require a separate process. This does not change the scheduler's execution model or its public method signatures.

WebSocket callbacks

Terminate handshake route middleware after onOpen for an accepted connection, or after sending an uncommitted handshake response. Keep connection publication atomic, and initialize the handler before termination can yield to a concurrent close callback.

Run handshake and opening deferred functions after middleware termination. Message and close callbacks drain their deferred functions after their lifecycle events; close retains connection context until cleanup finishes. Rendered response status determines handshake success, including handled redirects, while unhandled lifecycle failures suppress ordinary deferred work.

Honor disabled middleware and middleware parameters. Continue route termination after an ordinary failure and preserve its first exception. Cancellation skips remaining deferred work and stays contained at native callback boundaries. The callback collection is resolved only when the current coroutine already created one.

Reverb delivery and cleanup

Pass cancellation through protocol opening, message handling, recipient delivery, channel delivery and internal presence publication. An application listener that times out no longer causes a false protocol error or sends the same event to later recipients. Opening still releases its acquired connection slot before rethrowing cancellation.

When a connection closes, attempt every channel unsubscription once and rethrow the first failure afterward. A listener or webhook failure after removing one membership no longer strands the remaining memberships. Existing behavior for an unsuccessful shared-state write remains intact; this adds no retry or recovery registry.

Ordinary delivery failures retain the existing attempt-all behavior. Mandatory cleanup continues after failures, including cancellation, while canceled ordinary delivery stops.

Verification

Formatting, full source and type-fixture analysis, and the affected Console, Console integration, WebSocketServer and Reverb suites pass on the new branch. Earlier validation also covered the Sentry WebSocket context boundary and native Reverb integration.

Regression tests cover task and listener ordering, nested commands, success and failure eligibility, cancellation, middleware termination, context release, real listener deadlines and cleanup after a channel failure. The new cases fail against the previous implementations.

An isolated empty-message benchmark measured about 0.35 microseconds of additional callback work, with no deferred collection allocated when unused. This is a callback microbenchmark, not an end-to-end throughput measurement. CI runs the full framework suite and supported service matrix.

High-Level Assessment

The PR’s lifecycle-boundary approach is appropriate: deferred callbacks must run within the coroutine that owns task or connection state, while cancellation must retain distinct semantics from ordinary failure. A shared generic cleanup wrapper was considered, but scheduler exceptions may escape whereas native WebSocket callbacks must contain and report failures, making localized implementations clearer and safer.

Greptile Summary

Completes deferred-callback and cleanup boundaries for scheduled tasks and WebSocket callbacks while improving cancellation propagation and best-effort Reverb cleanup.

• Runs scheduled-task deferred callbacks according to the task’s final success, failure, or cancellation state.
• Terminates WebSocket handshake middleware and drains lifecycle-specific deferred callbacks.
• Propagates coroutine cancellation through Reverb delivery paths.
• Attempts every channel unsubscription before rethrowing the first cleanup failure.
• Documents scheduler process sharing and WebSocket deferred-callback behavior.
• Adds regression coverage for lifecycle ordering, cancellation, failure handling, and cleanup.

Confidence Score: 5/5

The PR appears safe to merge, with no outstanding or newly introduced actionable defects identified.

The only post-review modification is a non-functional clarification in the Reverb worker fanout path, and the current lifecycle, cancellation, deferred-work, and cleanup changes are supported by targeted regression coverage with no confirmed rule violations.

1. Canceled fan-out reaches later workers 🐞 Bug ≡ Correctness

Description

dispatchSynchronously and dispatchInternallySynchronously rethrow cancellation from local
channel delivery, but fanOutToOtherWorkers still catches the same exception as an ordinary failure
and continues its worker loop. When Server::sendMessage is canceled for one worker, the event is
still attempted on every later worker before cancellation reaches the caller.

Code

src/reverb/src/Protocols/Pusher/EventDispatcher.php[R90-91]

+            } catch (CanceledException $throwable) {
+                throw $throwable;

Evidence

The newly added catches stop local channel iteration immediately when cancellation occurs, but the
shared fan-out helper catches every Throwable from sendMessage, records it, and continues
iterating workers. Existing cancellation coverage only triggers cancellation during local channel
broadcasting and explicitly expects no worker send, so it does not exercise cancellation from the
worker fan-out itself.

Added the missing void return type to the WebSocket opening callback. The same omission in Telescope’s deferred storage callback is corrected in a separate commit. Both changes leave behavior unchanged.

We declined the worker fan-out cancellation finding after tracing the native Swoole send path. It does not suspend the coroutine with the framework’s protocol payload, so a mock that throws cancellation there would describe behavior the real transport does not have.

The existing WebSocket and Telescope suites, formatting, and full static analysis pass. CI passed before these two annotations; the new run is underway. Greptile found no actionable issues. Cubic could not review because its trial allowance is exhausted. Docstring-coverage percentages are not a requirement for this repository.

@binaryfire Thanks for the detailed validation.

The worker fan-out cancellation finding does not apply to the native Swoole send path. A mock that injects framework-protocol cancellation at that point would not represent production behavior. I withdraw that finding.

The void return-type additions are type-only changes. The reported test, formatting, and static-analysis results cover the affected areas.

Learning: In the Reverb worker fan-out path, the native Swoole send operation does not suspend the coroutine with the framework protocol payload. Do not require regression tests that inject `Swoole\Coroutine\CanceledException` from a mock at that send operation, because that mock does not represent production transport behavior.

Acknowledged. The void annotations are behavior-neutral, and the native Swoole send-path explanation addresses the worker fan-out cancellation concern. With the reported test, formatting, and static-analysis results, I have no additional actionable findings.

@binaryfire I don't have visibility into the trial allowance claim (that's handled by the account/billing side, and I can only go by what's in the thread), but I do have the full diff here, so I can weigh in on the one substantive point that's still open.

The worker fan-out decline looks right to me. The CanceledException rethrows you added to dispatchSynchronously/dispatchInternallySynchronously guard paths that actually suspend — application listener yields during channel broadcast or internal presence publication. The fanOutToOtherWorkers path just does non-suspending sendMessage calls to other workers; there's no coroutine boundary in between where a deadline could fire, so a mock that throws cancellation there genuinely models a transport the real Swoole send path doesn't have. Invoking it would mean propagating cancellation through code that can't cancel — so a catch (Throwable) continuing the loop there is behaviorally fine, not a bug. Keeping that finding out is the consistent call given the stated criteria of "no cancellation handling on native fan-out paths that do not yield."

The two pure annotation commits are also correct. void on the WebSocket opening callback and the Telescope Coroutine::defer closure match the framework's typing convention, and neither changes behavior since both closures return nothing today. No new coverage is warranted for them.

One thing worth being explicit about so it survives review: the reason the local delivery paths got the CanceledException catch while the fan-out didn't is the yield-vs-no-yield distinction, not inconsistency. A future reader checking the "all deliveries stop on cancellation" claim against fanOutToOtherWorkers may assume an oversight. A one-line comment at that fan-out loop noting it doesn't suspend would preempt that.

[greptile-apps]

Thanks for the update. The scoped void annotations address the omissions without changing behavior, and the cancellation rationale is clear given the native Swoole send path. I have no further actionable findings; pending CI is the remaining confirmation.

[greptile-apps]

Agreed. The fan-out path only constructs the pipe message and performs synchronous native sendMessage calls; it does not enter the application listener/channel delivery path or cross a coroutine suspension point. The CanceledException handling is therefore correctly limited to local delivery and internal publication paths that can actually suspend, while fanOutToOtherWorkers retains attempt-all behavior for ordinary send failures. A one-line comment documenting that yield-vs-no-yield distinction would be a useful maintainability note, but it is optional and not a correctness issue.

@binaryfire Looks consistent from my side. The worker fan-out comment added in fanOutToOtherWorkers is exactly the yield-vs-no-yield note that was missing, and it's placed where a future reader checking the "all deliveries stop on cancellation" claim would actually look. The two void annotations are behavior-neutral and match the framework convention, so no further coverage is warranted.

On the allowance point: I can't see the trial/billing state from the thread — that's handled on the account side, so I can't confirm or verify it. What I can confirm is that the final diff matches what you described: no executable changes in the last round beyond the comment, and no outstanding findings from the discussions I can see in this thread.

@binaryfire Confirmed. The second-round change is documentation-only and preserves the native Swoole transport qualification.

The void return-type corrections address the reported typing omissions. The cancellation finding remains withdrawn. The stated validation results and clean branch leave no remaining actionable CodeRabbit findings.

Learning: In the Reverb worker fan-out path, the native Swoole send operation does not suspend the coroutine with the framework protocol payload. Do not require regression tests that inject `Swoole\Coroutine\CanceledException` from a mock at that send operation, because that mock does not represent production transport behavior.

The second-round change adds a short comment explaining why native worker-pipe delivery does not need the cancellation catch used by local channel delivery. It preserves the qualification about the framework’s protocol payloads. No executable code changed in this round.

Both missing void declarations from the first round are also committed and pushed. Qodo withdrew its cancellation finding, and Greptile reviewed the final commit without finding further issues. All CI tests and checks pass, apart from Cubic’s neutral allowance check. CodeRabbit’s second formal review was rate-limited; its chat response confirmed the typing corrections.

The branch is clean, and all actionable review comments are addressed.

Thanks for the update. There are currently no Qodo findings on this PR, so no further Qodo action is needed. The cancellation-comment clarification and void declarations appear addressed in the diff; I can’t independently verify CI results or branch state here.

Thanks for the update. With the typing corrections committed, the native worker-pipe clarification added, and all actionable findings addressed, I have no further review concerns.

Thanks for the update. The cancellation-comment clarification and both void declarations address the previously discussed items. With no remaining actionable findings from this review, no further action is needed from Greptile.

Agreed. The final round is limited to the explanatory fanOutToOtherWorkers comment and the two behavior-neutral void declarations, with no remaining review findings from the discussion. The allowance status is account-side and cannot be verified from the code review.
