Data Collector V2 — production cutover - #69
Conversation
…иции Превращает composition, доказанную live в CHECKPOINT #1, в production-рантайм приложения и заменяет им V1-коллектор (900 строк composition + WS-обработчиков + очереди обогащения + ручного state machine в одном main.ts). Рантайм (`apps/collect-data/src/runtime/`): - `createDataCollector` — единственный composition root контура: ОДИН ExternalMessageBus, ОДИН ExternalMessageRecorder с двумя storage-политиками, PolymarketSource/CexSource V2, Discovery/Coordinator/Finalizer; - `DataCollector` — lifecycle и расписание: recorder-first старт с полным откатом частичного запуска, тик оркестрации владельцев состояния, идемпотентная best-effort лестница остановки в порядке CHECKPOINT; - `collectionLifecycle` — read-only проекция переходов рынка (DISCOVERED/COLLECTION_STARTED/FINALIZING/FINALIZED/DROPPED); - `processBootstrap` — DNS-обход под реальные V2-эндпоинты и ОДИН охраняемый путь остановки по сигналу; - `status()` — операционный снимок целиком из существующих getStats(). Bus остаётся явной точкой расширения: создаётся снаружи, передаётся фабрике, доступен независимым consumer-ам. Будущий Semantic Adapter подключится к нему, не завися от API коллектора. `main.ts` — тонкий bootstrap. Граница «внешний конфиг → V2» (включая формат `cex-config.json`) живёт в `DataCollectorConfig`; невалидная CEX-конфигурация теперь останавливает старт, а не оставляет прогон без половины датасета. Checkpoint переведён на ту же фабрику: второй копии composition в репозитории больше нет, verification-логика (PASS/FAIL, ring-буферы, exact-match, readback) осталась на своём слое. Тесты приложения (67): fan-out общего bus, отсутствие прямой связки source→recorder, наблюдаемость lifecycle, статус, старт (порядок/откат/ повторный) и остановка (идемпотентность/best-effort/таймеры).

Фиксирует, что именно из проверенной CHECKPOINT-композиции стало production
рантаймом, а что осталось verification-слоем; таблица переноса ответственностей
V1 → V2; аудит раскладки/именования/ротации/cleanup с явными отличиями
(сегмент {stream} в имени CEX-партиции, formatVersion 2, общий корень и
пересечение startup-cleanup двух политик).
Аудит collector-legacy: ни один из классов V1-контура не оказался
zero-consumer — все они остаются в живом употреблении у apps/bot, поэтому
удалена только зависимость приложения коллектора от @polymarket/cex-market-data.

Длинный прогон не завершает процесс сам: у createPublicClient() нет метода закрытия, и его keep-alive пул к gamma-api не освобождается ничем. Короткий режим checkpoint (две композиции подряд в одном процессе) заканчивается тем же состоянием, что и прогоны до этого MR, и выходит с кодом 0 — всё, чем владеет контур, освобождается. process.exit() сознательно не добавлен: он скрыл бы и будущие утечки.

Замер на production-масштабе (100 рынков, 6 бирж, ~1.4M записей): от SIGTERM до «Shutdown complete» — 79 секунд. Прежних 30 секунд не хватало, и SIGKILL от pm2 приходил ПОСРЕДИ финализации, теряя текущие окна записи. Прежний коллектор эту проблему прятал за process.exit() в конце shutdown.

…ealtime Клиент создавался фабрикой, использовался source/discovery/finalizer и не принадлежал никому: `PolymarketSource.close()` снимает СВОИ подписки, но shared websocket-соединения держит сам клиент, и закрыть их было некому. Теперь клиент — явная часть DataCollectorComponents (инъецируемая, как bus), а его `closeSubscriptions()` стоит в лестнице остановки сразу ПОСЛЕ закрытия source: раньше это рвало бы соединение под работающим итератором. Первичное объяснение зависания процесса («keep-alive пул Gamma, закрыть нечем») оказалось НЕВЕРНЫМ — метод закрытия у клиента есть, а сокеты gamma-api в замерах освобождаются сами. Диагностика на production-масштабе (100 рынков, 6 бирж, форсированные плановые рестарты CCXT) не оставляет ни одного сокета и завершает процесс сама; исходное зависание на 31-минутном прогоне воспроизвести не удалось, поэтому шаг добавлен как закрытие реального разрыва во владении, а не как доказанное лекарство. Заодно: - start() и close() сериализованы: сигнал во время запуска дожидается подъёма, иначе остановка гасила бы источники, которые запуск продолжает поднимать; - tick() регистрирует себя сам — остановка ждёт ЛЮБОЙ идущий тик, а не только запущенный планировщиком; - эндпоинты из конфигурации приложения доходят до клиента через форк окружения SDK (раньше GAMMA_API_BASE_URL/POLYMARKET_WS_URL молча игнорировались); - CEX-конфигурация требует явных булевых флагов потоков и хотя бы одного включённого; - отказ конверсии конфигурации логируется через logger, а не голым stack trace; - watchdog checkpoint-а печатает servername каждого оставшегося сокета — «какой именно ресурс» вместо «TCPSocketWrap»; - убран корневой export пакета (импорт корня запускал бы main.ts); - jest-алиасы выводятся из tsconfig, ESM включён по-настоящему.

Track every concurrent tick during shutdown. tick() stores only one active promise in _tickInFlight; overlapping calls can overwrite the first, and a later completion can clear the field while the earlier tick is still running. close() may then close the coordinator or finalizer before all collection work completes. Serialize concurrent ticks or retain and await every active promise, and add a regression covering this overlap sequence.

Update DataCollector.tick and the shutdown wait logic to track every overlapping
tick instead of overwriting _tickInFlight; either serialize concurrent calls or
retain all active tick promises and have close await all of them before closing
the coordinator or finalizer. Preserve cleanup so each completed tick is removed
from the active tracking state.

Align the SDK-client lifetime statement with the factory contract.
CHECKPOINT_MODE=short runs two compositions in one process. Each runComposition call invokes createDataCollector without options.client, which creates a new createPublicClient(...). Document one client per composition, or inject and reuse one process-wide client.

Node.js v26 process.exit stdout stderr writes may be truncated process.exit documentation
💡 Result:
In Node.js v26, calling process.exit forces the process to terminate immediately and synchronously, regardless of any pending asynchronous operations [1][2]. Because writes to process.stdout and process.stderr are sometimes asynchronous—especially when directed to pipes or files—calling process.exit can cause these writes to be truncated or lost entirely, as the process exits before the data can be flushed from the buffers [1][3]. The official Node.js documentation explicitly warns against this practice [1][4][2]. To avoid data loss, it is recommended to avoid calling process.exit explicitly whenever possible [1]. Instead, you should set the process.exitCode property and allow the Node.js event loop to terminate naturally once all pending work is complete [1][3]. If an error condition requires termination, throwing an uncaught error is generally considered safer than using process.exit [1][2]. If you must use process.exit, note that it bypasses the event loop, meaning any remaining asynchronous tasks—including those in 'exit' event listeners—will be abandoned [1][2]. For critical logging or I/O, ensure these operations are completed or awaited before triggering the exit [3]. Top results: [1][2][3]

Preserve the watchdog report before forced exit.
process.exit(3) follows console.error('Active handles:', ...). In Node.js v26, forced exit can truncate asynchronous process.stderr writes, so the Active handles output may be lost when stderr uses a pipe. Write the final diagnostics with fs.writeSync(2, ...), or exit from the final process.stderr.write callback.

`_tickInFlight` хранил ссылку на один тик, и второй затирал первый. Планировщик запускает следующий проход только после завершения предыдущего, но `tick()` публичен: прямой вызов может перекрыться с проходом цикла. В этом случае остановка дожидалась только последнего тика и закрывала координатор с финализатором прямо под первым, ещё работающим. Воспроизведено тестом (первый тик подвешен в fillSlots, второй проходит насквозь и завершается раньше): до исправления `bus.close` выполнялся, пока первый тик был жив. Теперь тики хранятся множеством, а `close()` дренирует его циклом — новых проходов планировщик к этому моменту уже не создаёт. Заодно по ревью: - документация больше не утверждает «один клиент на процесс»: граница владения — композиция, каждый `createDataCollector` без явного `client` создаёт свой (короткий режим checkpoint поднимает две композиции — клиентов там два); - диагностика watchdog-а пишется через `fs.writeSync(2, ...)`: запись в stderr асинхронна при pipe, и следующий `process.exit(3)` её обрывал. Проверено эмпирически — через pipe `console.error` терял вывод ЦЕЛИКОМ. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`GzipCompressor.compressFile` сначала переименовывает временный файл в `.gz` и только потом удаляет исходный `.jsonl` — это ДВА события. Тесты ждали появления `.gz`, а утверждали про удаление `.jsonl`, из-за чего ловили середину ротации: в листинге оказывались оба файла, и `expect(open).toHaveLength(1)` падал. Окно измерено на реальном компрессоре: оба файла сосуществуют в 4 из 40 ротаций. Под параллельной нагрузкой полного прогона монорепы этого хватало, чтобы сьют падал примерно раз через раз. Обе площадки переведены на `waitForCompletedPartitions`, которая ждёт фактического инварианта («архив есть И исходник удалён»). Проверено: на состоянии середины ротации старый предикат пропускал дальше, новый продолжает ждать. 12 прогонов сьюта подряд — без падений. Найдено при верификации MR-A: гонка существовала до этой ветки и к V2-контуру отношения не имеет. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Что сделано
Composition, доказанная live в CHECKPOINT #1, стала production-рантаймом
apps/collect-data, а V1-коллектор удалён. Постепенного рефакторинга V1 не было:это замена архитектуры на уже проверенную, а не улучшение старой.
main.tsиз 907 строк превратился в тонкий bootstrap; вся composition,lifecycle и расписание живут в

направление зависимости не даёт появиться
DataCollector.getMessages().нет; verification-логика (PASS/FAIL, ring-буферы, exact-match, readback) осталась
на своём слое.
DataRecorder/CexWindowRecorder/ExternalMessageRecorderиспользуются как есть; третьей реализации файловой логики не появилось.
onMarketLifecycle()+status()собраны из ужесуществующих
