fix(queue): stop failing jobs from retrying forever - #361
Merged

Conversation
redis-queue retries a failed job by enqueueing it as a new job whose attempt count starts again at zero, so the count never reaches the limit: a translation that kept failing retried every 30 seconds for hours (one target post was retried 1,117 times on 2026-08-21). Each retry also left the old record set to 'queued' with nothing left in Redis to process it, which filled the dashboard with 3,651 dead rows. The translation and review email jobs now count attempts in their payload, which the retried job carries over, and the plugin deletes the record a retry replaces. The worker doc explains how to tell dead 'queued' records from live ones. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
redis-queue's enqueue() returns false, without throwing, when it cannot reach Redis or store the job record. cdcf_enqueue_translation() only fell back on an exception, so it reported 'redis' and the translation was never queued. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- Around line 22-26: Update the retry flow around the `$wpdb->delete()` cleanup
so it only marks or removes the old job after the replacement `enqueue()`
succeeds. Preserve the old queued record when `enqueue()` returns false, using
the enqueue result to gate cleanup or pass it to the cleanup callback.

redis-queue fires redis_queue_job_retried whether or not enqueueing the retry succeeded, and does not pass the result. Delete the old record only when redis_queue_job_enqueued fired for the same job object, which enqueue() does only on success. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Problem
The Redis Queue dashboard showed 3,651 jobs stuck as "queued" (2026-04-29 → 2026-08-21) while Redis itself held nothing. They came from 25 translations, each retried over and over:
attempts < max_attemptsis always true. A translation that kept failing retried every 30 s for hours (post 757 →itwas retried 1,117 times on 2026-08-21). This started onceCDCF_Translation_Jobbegan throwing to trigger retries (d9906df, 2026-04-29).queued, but that job is no longer in Redis, so nothing ever processes it.All 25 translations did complete eventually. The dead records have been removed from production (a backup was kept).
Changes
CDCF_Translation_JobandCDCF_Review_Email_Jobcount attempts in their payload (_cdcf_attempt). The payload carries over into the retried job, soretry_attemptsand the backoff schedule now apply as configured.includes/retry-cleanup.php: onredis_queue_job_retried, delete the record the retry replaced (only while it is stillqueued).cdcf_enqueue_translation()now falls back to WP-Cron whenenqueue()returnsfalse(Redis unreachable or the record couldn't be stored). Before, it only fell back on an exception and reportedredisfor a job that was never queued.docs/redis-queue-worker.md: troubleshooting entry on telling deadqueuedrecords from live ones, including why "Reset stuck jobs" doesn't requeue anything.Testing
composer test(plugin): 35 tests OK. New tests cover the carried-over attempt count, backoff, record cleanup, and theenqueue() === falsefallback. Each failed before its fix.composer test(theme): 889 tests OK. A new test checks that the email job stops after 3 attempts.serialize()['payload'], which is captured aftershould_retry()updates the counter.Deploy
