Waaseyaa’s reported fix prevents a queue worker from acknowledging a message simply because none of its handlers recognized it. Instead, the worker raises a typed UnhandledQueueMessage failure, sends the delivery through bounded retry handling, and records an exhausted failure before rejecting the delivery. The change is described in an article dated September 11, 2026; check the version you maintain before treating these details as current release behavior.
Why could a message disappear without being handled?
In the reported implementation of Waaseyaa’s packages/queue, the worker pulls a delivery from its transport and checks registered handlers in turn. Each handler’s supports() method determines whether it can process the message.

The bug occurred when no handler accepted the message. Worker::handleMessage() exhausted the handler loop and returned normally. Its caller, processJob(), treated that normal return as success and acknowledged the delivery. The message could disappear without a handler running, a retry, or a failed-job record.
The mismatch was possible because dispatch accepts any object, while the default handler roster knows how to run Job objects. Accepting an object for dispatch does not ensure that a worker has a handler capable of consuming it.
How does the reported fix change message handling?
After checking the roster, handleMessage() now throws a typed UnhandledQueueMessage exception if no handler supports the message. That exception reaches the existing catch block in processJob() and is handled as a failure rather than as successful completion.
The reported implementation routes the failure through the worker’s existing bounded retry and backoff policy. For jobs, the attempt limit comes from Job::$tries; for other messages, it comes from WorkerOptions::$maxTries, which the article reports defaults to three attempts. The article does not specify the backoff schedule. The exception text identifies the message class without exposing its payload.

What happens when retries are exhausted?
The failure is recorded in the failed-job repository before the delivery is rejected. If writing the failure record fails, the delivery is not rejected; it remains reserved for lease recovery. This ordering avoids losing the original message because the failure store was unavailable.

What should you check when reviewing the repair?
Review the actual outcomes and their order, not just whether an exception is thrown:
- No supporting handler: the worker must not return normally and acknowledge the delivery as though handling succeeded.
- Retry and exhaustion: an unsupported message should follow the configured bounded retry policy, then be recorded as a failure before transport rejection.
- Failure-store outage: if recording fails, rejection should not proceed; the delivery must remain available for recovery.
- Supported messages: a custom handler that accepts a message should still run normally, and provider-managed jobs should retain their normal handling path.
- Dispatch contract: broad acceptance of objects at dispatch time must not be confused with a guarantee that a compatible consumer exists.
Which tests exercise the reported behavior?
The author describes a database-backed QueueServiceProviderUnhandledMessageTest using QueueServiceProvider, DbalQueue, DbalTransport, and DatabaseFailedJobRepository. It covers an unsupported message being released on its first attempt and durably recorded on the next, rather than acknowledged; a supported custom handler running once and being acknowledged; and a provider-managed Job running and being acknowledged normally.
A separate WorkerTest case uses a stub failed-job repository whose record() method throws. The reported assertion is that the delivery stays in_progress for lease recovery. This is an induced failure of the stub repository, not evidence that the real database repository was made to fail on demand.
The author reports 236 tests and 629 assertions for the Waaseyaa queue package unit and contract test suite after the change. That count is the author’s report and has not been independently checked against CI or a repository.
