fix(speakers): retry a killed bulk-send chunk once and resume without re-emailing - #598
Conversation
… re-emailing ProcessSpeakersEmailRequestJob had tries = 1 and timeout = 0: a chunk whose worker was killed mid-run (rolling deploy, OOM, scale-down) was re-served and failed without ever running again, and the failed() hook's own advice (re-send with should_resend=false) silently drops every speaker who ever received that email type from any earlier campaign, since the guard it relies on carries no date. - Bound the job's runtime (timeout 1200s) strictly below every queue connection's retry_after (1800s) and the db-fallback worker's --timeout (1400s), extracted into a reusable ResumableChunkJob trait alongside tries = 2 and a 300s backoff, so a retried attempt can never run concurrently with a still-live earlier one. - SpeakerService::triggerSendEmails stamps each chunk with dispatched_at once per run and strips any caller-supplied resume_since. - On a retry, the job sets resume_since = dispatched_at; the per-speaker closure in SpeakerService::sendEmails skips only speakers whose proof for this email type was written since that instant, before any promo-code or assistance side effect. should_resend passes through untouched - it answers a different question (skip anyone with any historical proof) and stacks with the resume check rather than replacing it. - PresentationSpeaker::hasAnnouncementEmailTypeSentSince adds the dated proof check; SpeakerActionsEmailStrategy::getAnnouncementType exposes the flow_event -> type mapping so the service can resolve it before process(). - Corrected the failed() operator hint, which previously recommended should_resend=false unconditionally - now a warning, since that guard also silently skips every speaker from any earlier, unrelated campaign.

Dispatch selection emails after the proof transaction commits
SpeakerActionsEmailStrategy::process() dispatches through PresentationSpeakerSelectionProcessEmailFactory::send() before creating SpeakerAnnouncementSummitEmail. With Redis after_commit=false, a worker can execute the queued email before the transaction commits. If the transaction rolls back, the retry finds no proof in hasAnnouncementEmailTypeSentSince() and can dispatch the same email again. Use afterCommit() or an atomic outbox, and add a termination-window integration test.

Confirmed: PresentationSpeakerSelectionProcessEmailFactory::send() does run before the SpeakerAnnouncementSummitEmail proof is created, and with after_commit=false on the redis connection a fast worker could process the mail before the wrapping transaction commits. This is pre-existing behavior this PR doesn't touch — the ordering inside SpeakerActionsEmailStrategy::process() is unchanged — and it's the same trade-off this PR's plan already documented: "A kill between the redis push and the commit re-emails that one speaker on the retry. Bounded to one speaker per kill; accepted."
Moving to an afterCommit/outbox pattern would touch the same dispatch path shared by all ten services on ParametrizedSendEmails, not just this job — platform-level, out of scope here. Leaving as a documented accepted risk.

@smarcet, thanks for the clarification. The dispatch-before-proof termination window is pre-existing and unchanged by this PR. The retry behavior bounds the duplicate-email risk to one speaker per killed chunk.
An afterCommit() or atomic-outbox change affects the shared ParametrizedSendEmails dispatch path. It is out of scope for this PR. Would you like me to open a follow-up GitHub issue for that platform-level change?

Learning: In OpenStackweb/summit-api speaker bulk-email processing, `PresentationSpeakerSelectionProcessEmailFactory::send()` can dispatch before `SpeakerAnnouncementSummitEmail` proof creation, while Redis has `after_commit=false`. A kill between queue dispatch and transaction commit can cause one speaker to be re-emailed on retry. This pre-existing bounded risk is accepted for PR `#598`. An `afterCommit()` or atomic-outbox solution is platform-level work because the dispatch path is shared by ten services using `ParametrizedSendEmails`.

Learning: In the speaker email flow, `SpeakerActionsEmailStrategy::process()` creates a `SpeakerAnnouncementSummitEmail` proof only after `PresentationSpeakerSelectionProcessEmailFactory::send()` has dispatched that speaker’s email job. Therefore, when overlapping same-summit, same-type campaigns use the date-based `resume_since` check, a proof from the other campaign can affect excerpt run attribution but does not cause a missed email.
You are interacting with an AI system.
- An unmapped email_flow_event (getAnnouncementType() returns null) must not be skipped by the resume check - the "!is_null($announcement_type) &&" guard short-circuits before calling hasAnnouncementEmailTypeSentSince(), whose $type parameter is non-nullable string; dropping that guard would throw an uncaught TypeError (extends \Error, not caught by sendEmails' catch (\Exception)) instead of just letting the speaker through. - The resume-skip's early return happens before generateSpeakerAssistance(), not just before getPromoCode() - asserted by spying on IPresentationSpeakerSummitAssistanceConfirmationRequestRepository::getBySpeaker(). newFixtureSpeaker() gains an optional $published flag (default false, no change to existing call sites) so a fixture speaker's presentation can satisfy hasAcceptedPresentations()'s DQL (p.published = 1) and make generateSpeakerAssistance() actually reach the repository instead of short-circuiting to null before it.

…ion type @var SpeakerAnnouncementSummitEmail[] described it as a plain array; at runtime it's a Doctrine Collection (implements Selectable), which is why matching() already worked on it. PHPStan flagged the call as "Cannot call method matching() on array" for both the pre-existing hasAnnouncementEmailTypeSent() and the new hasAnnouncementEmailTypeSentSince(). Docblock-only change, no behavior change.

Deep review of #598 flagged that ResumableChunkJob's core safety argument - job timeout strictly below every queue connection's retry_after, so a retried attempt can never overlap a still-live earlier one - had no regression coverage, despite the PR description claiming it did. A future change to DB_QUEUE_RETRY_AFTER/ REDIS_RETRY_AFTER, or to ResumableChunkJob::$timeout, could silently reintroduce concurrent execution of the same chunk. Add testTimeoutStaysStrictlyBelowRetryAfterForEveryQueueConnection to assert $job->timeout against both the database and redis connections' retry_after. Red-green verified by temporarily setting ResumableChunkJob::$timeout to 1800 (equal to retry_after) and confirming the assertion fails, then restoring it.

What this does
ProcessSpeakersEmailRequestJobhadtries = 1andtimeout = 0. A chunk whose worker was killed mid-run (rolling deploy, OOM, scale-down) sat reserved untilretry_afterelapsed, was re-served, and was marked failed without ever running again. The operator had to re-send the chunk by hand, and thefailed()hook's own advice ("re-send withshould_resend=false") was actively wrong for a deliberate second campaign of the same email type:hasAnnouncementEmailTypeSentcarries no date, so it silently skips every speaker who ever received that type, from any earlier campaign.triesis now2, with the job's runtime bounded strictly below every queue connection'sretry_after(1800s, both redis and database) and the database-fallback worker's--timeout(1400s):timeout = 0does not mean "no job-level bound, use the worker's" — Laravel writes the job's$timeoutproperty into the queue payload, andWorker::timeoutForJobprefers it over the worker option because0is notnull, sopcntl_alarm(0)cancelled the alarm outright. Without an explicit bound belowretry_after, raisingtriesto2would let a hung (not killed, just slow) chunk be re-served to a second worker while the first was still running it — true concurrent execution of the same chunk.timeout/tries/backoffand the retry-activation logic live in a newApp\Jobs\Emails\Traits\ResumableChunkJobtrait, mixed into the job.A retried chunk resumes rather than restarts:
SpeakerService::triggerSendEmailsstamps every chunk withdispatched_at(once per run) and strips any caller-suppliedresume_since. On a retry,ProcessSpeakersEmailRequestJob::handle()setsresume_since = dispatched_at; the per-speaker closure inSpeakerService::sendEmailsskips only speakers whose proof for this email type (PresentationSpeaker::hasAnnouncementEmailTypeSentSince, new) was written at or after that instant — before any promo-code or assistance side effect, so a retry never leaves an orphan promo code for a speaker it must not re-email.should_resendpasses through completely unmodified: it answers a different question (does the operator want to re-email anyone with any historical proof of this type?) and stacks with the resume check rather than replacing it. Forcingshould_resend=falseon every retry was considered and rejected — a deliberate second campaign of the same type, killed partway through, would find the first campaign's proof on every speaker and skip all of them silently.SpeakerActionsEmailStrategy's flow_event → announcement-type mapping is now a publicgetAnnouncementType()method (was an inlineswitchinprocess()) so the service can resolve the type ahead of the resume check without duplicating it.The
failed()operator hint is corrected: it previously told the operator to re-send withshould_resend=falseunconditionally, which is the same undated-skip hazard described above. It's now a warning about that hazard rather than a recommendation, and the docblock reflects thatfailed()now only fires once the automatic retry has also failed.Deliberate behavior notes
