Cohort/era WHERE clause carried `OR year_built IS NULL`, meant to let avito's
frequently-missing year_built field through the filter. In practice this let
ANY-era avito listing bypass the cohort filter entirely once cohort_year_min/
max were set — pollution bug: khrushchevka target could pull in a modern avito
comp with no year parsed, and vice versa.
Narrow the escape to `OR (year_built IS NULL AND source <> 'avito')` in both
places that must stay in sync:
- _COMMON_WHERE (Tier S/H, ~estimator.py:4210)
- Tier W inline SQL copy (~estimator.py:4640)
Non-avito NULL-year rows (cian/domklik/etc without a parsed year) still pass
through untouched; avito NULL-year rows now must satisfy the same
year_built BETWEEN cohort_year_min AND cohort_year_max test as everything
else.
Added tests/test_estimator_avito_cohort_null_2013.py: SQL-source assertions
that both cohort blocks carry the new guard, stay in sync (exactly 2
occurrences), and that the old unscoped escape is gone. A full DB-backed
integration test was impractical — this suite's estimator tests run against
a dummy DATABASE_URL with no live DB.
Удаляет весь `app/services/scrapers/` (16 файлов, ~7100 строк) — Part D (D1-D5)
убрал всех внешних вызывающих, 0 runtime importers подтверждено grep'ом на main.
Заодно:
- удалены 7 осиротевших локальных probe/sweep-скриптов (tradein-mvp/scripts/),
импортировавших уже-удалённые или удаляемые сейчас legacy-модули
- тест-хирургия по 65+ файлам: DELETE прямых legacy-юнит-тестов, RETARGET
тестов, тестирующих ещё живую бизнес-логику (переключены на scraper_kit.*
эквиваленты, включая quality-gate #781/#753/#754/#755/#773/#740), partial-delete
golden-parity тестов, потерявших legacy-оракл
- kit save_listings/AvitoScraper/etc. требуют инжектируемые matcher/config —
ретаргетированные тесты обновлены под новую сигнатуру (RealScraperConfig(),
MagicMock HouseMatcher, region_code=66)
Полный pytest suite зелёный (2255 passed, 6 skipped) кроме известного флейка
#2208 (test_search_cache_hit, не связан со scrapers).
Топология подтверждена перед удалением (docker-compose.prod.yml): tradein-backend
(uvicorn app.main:app) — SCHEDULER_ENABLE=false; tradein-scraper (python -m
app.scheduler_main) — SCHEDULER_ENABLE=true + USE_KIT_SCHEDULER=true. Kit-путь
(_run_kit_scheduler → scraper_kit.orchestration.scheduler + product_handlers)
самодостаточен: не импортирует ничего из app.services.scheduler.scheduler_loop
или app.services.scrape_pipeline. Все НЕ-sweep джобы, которые kit-scheduler
диспетчерит через build_product_handlers, идут напрямую в app.tasks.*/
app.services.* (либо lazy-импортят import_rosreestr_dkp/_execute_cian_backfill
из scheduler.py) — мимо удаляемой legacy-машинерии.
app/services/scheduler.py: 2098 → 418 строк. Удалено: scheduler_loop,
get_due_schedules, reap_zombies, _claim_run, _defer_next_run_at, _spawn_tracked/
_drain_inflight/_inflight_tasks, все 27 trigger_*_run-функций, импорт
app.services.scrape_pipeline, константы SCHEDULER_TICK_SEC/ZOMBIE_THRESHOLD_HOURS
(достижимы были только через удалённый scheduler_loop-путь). Оставлено (живые
импортёры вне удалённого): compute_next_run_at + has_running_run (admin.py),
import_rosreestr_dkp + _execute_cian_backfill (lazy-импорты в
product_handlers.py — job-тела kit-handler'ов).
main.py: убран `from app.services.scheduler import scheduler_loop` + lifespan-блок
запуска (`if settings.scheduler_enable: asyncio.create_task(scheduler_loop())`);
прод-backend всегда шёл с SCHEDULER_ENABLE=false, так что это был мёртвый код.
scheduler_main.py: убрана ship-dark развилка #2192 (USE_KIT_SCHEDULER=false →
legacy scheduler_loop fallback) — _run_kit_scheduler() теперь безусловный путь.
Поле settings.use_kit_scheduler оставлено в конфиге (Settings extra="ignore"
защищает от startup-краха на leftover env var), но на ветвление не влияет.
app.services.scrape_pipeline: 0 runtime-импортёров в app/+scripts/+packages/
после этого PR (только тесты, которые Part E удалит вместе с самим файлом) —
подтверждено grep. scrape_pipeline.py не тронут (Part E).
Тесты: удалены test_house_imv_backfill_scheduler.py (100% legacy-триггер,
backfill_house_imv сервис покрыт в test_house_imv_backfill_browser_flag.py /
test_backfill_wave2.py) и test_kit_registry_completeness.py (parity-инвариант
против удалённого dispatch, дублирует test_scraper_kit_scheduler_parity.py).
Точечно вырезаны "Scheduler wiring" секции (trigger_fn_exists/dispatch_branch_
wired/runs_in_executor) из ~10 файлов, тестирующих сами task-функции — сами
task-тесты (SQL-shape, миграции, fake-db поведение) оставлены нетронутыми.
test_scheduler.py: 825 → ~90 строк (остались только compute_next_run_at-тесты).
test_scraper_kit_scheduler_parity.py: убрана golden-parity секция против
удалённого scheduler_loop (SOURCE_TO_OLD_TRIGGER/_drive_old_one_tick/
test_routing_parity_per_source), остальное (claim/reap_zombies/dispatch/
registry-shape тесты kit-модуля) сохранено — источник этих инвариантов не
app.services.scheduler, а сам scraper_kit.orchestration.scheduler.
test_scheduler_main.py: 2 теста, патчившие app.services.scheduler.scheduler_loop,
переведены на монкипатч sm._run_kit_scheduler (единственный путь после этого PR).
test_sweep_imv_phase.py:171-371 (6 прямых импортов run_avito_city_sweep из
scrape_pipeline) намеренно НЕ тронуты — Part E.
Verify: полный pytest 3179 passed / 6 skipped / 1 known-unrelated fail
(test_search_cache_hit, #2208, не связан с этим PR); ruff 0.7.4 чист на всех
изменённых файлах; `python -c "import app.main; import app.scheduler_main"` OK.
Group E4 (final, highest-risk step of scraper_kit migration epic #2277):
estimator.py and house_imv_backfill.py's avito_imv/cian_valuation/
yandex_valuation call sites now import from scraper_kit.providers.* instead
of app.services.scrapers.*, following the exact wiring proven safe by E1/E2/E3
(#2334/#2335/#2336):
- estimator.py's avito IMV (_get_or_fetch_imv_cached, both call sites) and
house_imv_backfill.py's _process_one_house: add config=RealScraperConfig()
— kit's evaluate_via_imv silently drops the configured proxy without it.
- estimator.py's cian valuation (Stage 9): add config=RealScraperConfig() —
mandatory kwarg on the kit function (TypeError if omitted).
- estimator.py's yandex valuation: add config=RealScraperConfig() (mandatory)
and delay_provider=get_scraper_delay — without it kit silently falls back
to a hardcoded 5.0s throttle instead of the DB-configured anti-ban delay.
- All exception classes imported consistently from the same kit module as
evaluate_via_imv (not just the function) — mixing legacy/kit exception
classes would break `except IMVAddressNotFoundError` etc. via identity
mismatch (caught by an existing test that assumed the legacy class,
fixed alongside).
Observability: both cian_valuation and yandex_valuation graceful-degradation
except-blocks upgraded from logger.warning to logger.exception. GlitchTip's
LoggingIntegration listens at event_level=ERROR (main.py/scheduler_main.py) —
a WARNING never reaches GlitchTip as an event regardless of exc_info, so a
future config-wiring mistake at these call sites needs ERROR level to be
visible in monitoring.
house_imv_backfill.py: RealScraperConfig is imported lazily inside
_process_one_house (not at module level) to avoid a circular import —
app.services.scraper_adapters imports backfill_house_imv/
process_houses_imv_batch from this module at module level. Verified via
direct import in both orders plus a full `app.main` import.
Also fixes a stale docstring claiming process_houses_imv_batch is "not wired
into scheduler" — it is, via scrape_pipeline.py's run_avito_city_sweep.
Test updates: 2 pre-existing tests (test_backfill_wave2.py) mocked the legacy
IMVAddressNotFoundError/IMVEvaluation/IMVGeo classes, now updated to import
from scraper_kit to match the production exception identity. Added
config=/delay_provider= regression-guard asserts to the relevant estimator
and backfill tests, mirroring the existing #2306 cian_price_history pattern.
Legacy app/services/scrapers/{avito_imv,cian_valuation,yandex_valuation}.py
are untouched and still imported by cian_history_backfill.py's valuation
block (separately scoped, not touched here) — revert is a clean single-commit
revert, no schema/data migration involved.
Migrates legacy app.services.scrapers.* imports to scraper_kit equivalents for
house_imv_backfill.py, avito_detail_backfill.py, cian_history_backfill.py,
ekb_geoportal_ingest.py, and yandex_detail_backfill.py, proving parity via
tests/support/parity.assert_parity per the epic's gate (#2304).
newbuilding_enrich_backfill.py and yandex_newbuilding_sweep.py are left fully
on legacy imports: both call into scraper_kit.providers.{cian,yandex}.newbuilding,
which construct BrowserFetcher(source=...) without the now-mandatory endpoint=
kwarg (issue #2322, verified still open against the actual provider source, not
just issue status) -- no caller-side fix is possible, matching Group A's (#2305)
precedent for the same bug in admin.py.
Config-gated kit function footguns found and fixed (Group B #2306 pattern):
- avito fetch_detail's backconnect-on-403 retry silently drops when config=
is omitted -- now passes config=RealScraperConfig() explicitly, with a
regression test proving the gate.
- kit AvitoScraper's constructor now requires ScraperConfig positionally --
wired via RealScraperConfig(), which _rotate_ip() reads for
avito_proxy_rotate_url.
- BrowserFetcher(source=...) call sites (house_imv_backfill, avito/cian
detail backfills) now pass the mandatory endpoint=settings.browser_http_endpoint.
New footgun discovered (NOT #2322, flagged for follow-up): kit's
build_warmed_session() builds its curl_cffi session via _build_detail_session()
with no config parameter at all, unlike fetch_detail -- migrating it would
silently drop the sticky MGTS-proxy egress on avito_detail_backfill's
warm-batch path (the prod default). Left build_warmed_session/
_AVITO_WARM_SEARCH_URL on legacy imports, documented inline.
Refs #2310
Group B of the scraper_kit migration epic (#2277): switch the three files'
internal dependency imports from legacy app/services/scrapers/* to their
byte/structurally-identical scraper_kit equivalents, proven via the new
parity harness (tests/support/parity.assert_parity, #2304). Public API of
all three files is unchanged, so no callers needed updating.
- cian_price_history.py: fetch_detail/save_detail_enrichment now from
scraper_kit.providers.cian.detail. Wires config=RealScraperConfig() at
the call site — kit's fetch_detail only reads cian_proxy_url when an
explicit config is passed, unlike legacy's always-on settings read;
without this the admin-triggered backfill would silently drop its
datacenter-IP proxy (#806) after the import swap.
- cian_session.py: extract_state now from scraper_kit.cian_state_parser
(byte-identical to legacy).
- yandex_price_history.py: ScrapedLot now from scraper_kit.base
(byte-identical fields/methods; record_yandex_price_history only reads
lot.* via duck-typing, no isinstance checks).
New tests/test_scraper_kit_pricehistory_session_parity.py proves the
migration delta specifically (extract_state, ScrapedLot.model_dump(),
fetch_detail+DetailEnrichment with config injection, and the own-session
proxy-kwarg wiring). Full backend suite passes (3145 passed, 6 skipped,
1 pre-existing unrelated failure confirmed on unmodified forgejo/main).

Fixed ANCHOR_TIMEOUT_SEC=240 guillotined every cian anchor when running via
USE_PROXY_POOL_BROWSER=true: each SERP fetch goes through camoufox with relaunch
on proxy swap (13-45s/page), and an anchor = 4 room-buckets x pages_per_anchor
SERP fetches + detail_top_n details + houses-enrich >> 240s. save_listings never
ran, lots_fetched=0, and after 3 consecutive skips the run was mark_banned.

duration). Applied to both the scraper-kit copy (strangler target) and the active
app.services.scrape_pipeline copy that run 581 actually hit.
