Fix queue publication and worker lifecycle correctness - #562
Conversation
Replace the payload-only unique job context with a weak dispatch lock context that carries exact unique and debounce ownership through payload creation, deferred dispatch, transaction callbacks, failover, scheduling, queued listeners, and unique broadcasts. Release only the owner acquired by the current dispatch, retain hidden metadata for unserializable jobs, close failure and rollback paths, and mark ownership accepted before success listeners run. Add the UniqueJobSkipped event and complete queued-listener debounce behavior. Expand focused coverage for stale-owner safety, resolver failures, cancellation, after-response and after-commit dispatch, broadcast rescue, scheduling, failover, context propagation, and queue instrumentation cleanup.
Have BusFake and QueueFake consume live dispatch ownership only after they successfully record the original command or job. Forwarded work remains owned until the real dispatcher or queue accepts it, while serialization failures retain ownership for cleanup. Cover every fake terminal, serialized command identity, unique suppression, debounce provenance, forwarding, and explicit fake lock cleanup.
Move deferred and background queue scheduling into a shared CoroutineQueue base while preserving their execution strategies and SyncQueue inheritance. Execute raw payloads through the sync-family queues instead of silently discarding them. Capture compact dispatch-lock release snapshots for delayed in-memory jobs, accept ownership only after scheduling succeeds, and release locks when graceful shutdown drops pending timers. Cover immediate, delayed, after-commit, cancellation, shutdown, registration failure, null-queue, and queue:retry behavior.
Cache lock and binding capabilities on each physical PDO connection generation, including correct MySQL, MariaDB, PostgreSQL, and SQLite thresholds with invalidation when the PDO is replaced. Chunk only oversized database queue batches, wrap multi-statement batches in one transaction, reject false inserts, and accept every stored member before dispatching success events. Preserve a conservative fallback for custom non-PDO connections. Cover capability caching and replacement, exact binding boundaries, minimal chunking, transaction rollback, success-listener failures, ownership handoff, and a real oversized SQLite batch.
Use the source-aware SHA cache for single queue scripts and replace nested pipeline transactions with one same-slot Lua bulk command. Prepare all payloads before publication, require an exact completion count, accept every stored member before success events, and preserve after-commit ownership. Split Horizon classification from publication stamping so delayed, transactional, raw, and retried jobs retain their metadata while pushedAt reflects the actual Redis write. Keep JobPending and JobPushed aligned with confirmed publication. Cover standalone and Cluster command shapes, mixed immediate and delayed batches, partial script failures, wrong counts, lifecycle failures, ownership, event ordering, retries, metadata preservation, and context cleanup.
Widen JobQueued identifiers to the queue contract's mixed return type so drivers can expose native identifier objects without conversion or type errors. Add a mocked Beanstalkd dispatch regression proving the exact Pheanstalk JobIdInterface instance reaches the event listener unchanged.
Make WaitConcurrent completion include child-deferred cleanup, then run queue worker lifecycle steps, timeout checks, signal callbacks, and shutdown drains in short-lived owned coroutines. This prevents daemon and timer coroutines from retaining pooled resources and removes the shutdown busy-loop race. Keep native signal handlers limited to ordered state capture, emit JobInterrupted only for jobs actually notified, and add connection and queue context to WorkerStopping. Preserve cancellation identity, worker context, protected extension points, and event ordering. Cover deferred cleanup ordering, cancellation, configured context, signal order, interruption events, graceful and immediate shutdown, timeout handling, and one-slot database pool reuse.
Document skipped unique jobs, debounced listeners, graceful local-queue lock cleanup, worker interruption and stopping context, Redis bulk limits, and the fact that successful concurrent waits include deferred cleanup. State the multi-node debounce guarantee accurately as best-effort, keep idempotency guidance explicit, record the intentional Redis bulk implementation difference, normalize package README ordering, and remove the completed Database Queue capability consumer from the framework TODO.
Record the verified defects, complete design invariants, upstream changes, implementation boundaries, testing strategy, and completion criteria for dispatch ownership, queue publication, database capabilities, Redis batching, Horizon timing, and worker resource lifetimes. The plan also records rejected complexity and operational limits so later maintenance preserves the intended correctness and performance characteristics.
Mark the queue-facing lock and binding capability accessors as internal at their definition sites. They remain public for cross-package framework use while the facade documenter no longer advertises them on DB, where supported non-PDO connections cannot provide them.
Record that the PDO capability accessors are internal queue-facing probes and must stay outside the generated DB facade surface. This preserves support for non-PDO connection implementations without widening the database contract.

using a blocking Queue::pop() that verifies SIGTERM interrupts the idle worker.

Explain that block_for=0 can defer worker termination, pause checks, and interruption delivery until another job becomes available. This documents the intentional Redis blocking tradeoff without adding unsafe pop cancellation or changing the Laravel-compatible configuration surface.

Summary
This change fixes queue ownership, publication, and worker lifecycle defects found while preparing transactional outbox support. It does not add an outbox API.
The main change is that unique and debounce locks now remain owned by the dispatch operation until a queue confirms acceptance. That ownership survives payload creation, after-commit and after-response deferral, scheduling, failover, queued listeners, unique broadcasts, fakes, and local in-memory queues. Failure and rollback paths release only the exact owner they acquired, so stale cleanup cannot delete a newer unique lock.
It also makes database and Redis bulk publication report acceptance only after storage is confirmed, fixes raw sync-family payload execution, preserves Horizon classification until actual Redis publication, and prevents worker and signal coroutines from retaining pooled resources for the process lifetime.

The queue, event, coroutine, Bus, Queue, and Horizon documentation now covers the new events, listener debounce behavior, local delayed-job shutdown limits, Redis bulk boundaries, worker stopping context, and deferred-cleanup guarantees. Package README ordering is normalized and the completed Database Queue capability probe is removed from the framework TODO.
Compatibility
Laravel-shaped public APIs remain compatible. The
JobQueuedidentifier is widened to match the queue contract, andWorkerStoppinggains Laravel-positioned nullable connection and queue context while retaining Hypervel's existing named boolean. Correctness fixes intentionally do not preserve Laravel behavior where Laravel silently drops raw sync payloads or reports queue ownership too early.Verification
Verified with PHP CS Fixer, both PHPStan configurations, the full parallel test suite, the Testbench package contract suite, dogfood tests, and focused queue, Redis, database, Horizon, worker, signal, facade-documenter, and coroutine coverage.
