The /weather LiveView was timing out on pod restart because latest_weather_grid/1 ran load_weather_grid_from_db/1 synchronously on cache miss — that query reads 176k hrrr_profiles rows with two huge JSONB columns (profile array + duct_characteristics), and JSONB decoding blocked the LiveView process past the 15-second pool ownership timeout. On cache miss latest_weather_grid/1 now returns empty immediately and kicks off a deduped background fill through GridCache.claim_fill/1 (a per-valid_time ETS lock so N concurrent mounts after restart don't each fire the slow query). When the fill completes it broadcasts weather:updated, and the handle_info in WeatherMapLive hits the warm cache and pushes rows over the socket. Added load_weather_grid/1 as a synchronous sibling for tests and any caller that genuinely needs inline data. Tests updated to use it and to clear GridCache in setup so ETS state doesn't leak between cases. Also untrack k8s/secret.yaml and add both it and k8s/*-secret.yaml to .gitignore — those manifests hold plaintext SMTP and database credentials that should not live in the repo. Secrets already in git history should be rotated separately. |
