Investigated with a real curl_cffi capture (HTTP 200, 46 cards): the Avito
SERP lazy-renders — data-marker="item-date" appears only on the top
above-the-fold cards (~10/46), so ~79% of cards have no date in the raw HTML
curl_cffi receives. The marker wasn't renamed; the field is just absent.
But every listing carries sortTimeStamp (epoch-ms) in the embedded per-item
JSON (56 occurrences/page) — the line-266 'state empty' note was stale. Map
item_id (= DOM data-item-id) -> sortTimeStamp -> date as the primary source,
keep the DOM item-date + _parse_relative_date as fallback for the top cards.
Verified on the real capture: 42/46 = 91% coverage (was ~21% DOM-only),
clearing the >80% DoD bar. Adds a distilled real-structure fixture
(avito_serp_sample.html) + unit test covering both the JSON (lazy card) and
DOM (top card) paths.
Refs #726
Add global request delay floor + per-source delay management.
- 054: seed 'global'=0 + per-source rows (avito=7, cian=5, n1=5, domrf=5, rosreestr=5)
using ON CONFLICT DO NOTHING; reuses existing 053 table from #484
- scraper_settings.py: get_scraper_delay() = max(per_source, global); _GLOBAL_KEY,
refactored _get_setting_cached(); preserved yandex umbrella alias logic
- admin.py: GET /scraper-settings + PUT /scraper-settings/{source} (ge=0.0, le=60.0);
cache invalidation on update; CAST(:d AS numeric) per psycopg v3
- avito/cian/n1 scrapers wired (yandex was wired by #484)
- 18 unit tests pass (10 original updated for max() + 8 new global delay tests)
Closes follow-up gap from #486 (Cian admin slider min=0 now accepted by API).
DOM-путь (_dom_card_to_lot) — основной для Avito: mobile API отдаёт
бан, формат __initialState__ устарел, так что почти все объявления
идут через него. Но он не извлекал фото вообще, а адрес брал мёртвым
селектором [class*="geo-address"] — поэтому объявления Avito оставались
без фото (серый блок в Сводке) и с заглушкой «Екатеринбург (Avito)».
Теперь:
- фото — из <img itemprop="image"> карточки-слайдера (до 5 шт);
- адрес — первый <p> внутри data-marker="item-location" (улица + дом).
Селекторы проверены на живой выдаче Avito.
