grabowski	6eafb353b1	feat: RID large-dam daily collector — Mae Ngat storage/inflow/outflow ... POST app.rid.go.th/reservoir/api/dams (open, archive >=2009) collected hourly into rid_dams + rid_reservoir_daily; backfill script fetches only missing days so reruns repair holes and are safe alongside the live collector. /api/stats counts the new table via an engine fallback that works when HII collection is disabled. Mae Ngat (DAM_ID 200103) hit 113% usable capacity with ~19 MCM/day inflow in the Oct 2024 flood — candidate features for the next retrain.	2026-08-13 10:29:34 +07:00
grabowski	731f10910e	perf: stale-while-revalidate caching, bigger executor, cheap DB health probe ... Third on-box run: p50s healthy everywhere but tails at 60s — when a TTL expired under load, every concurrent miss parked an executor thread on the single-flight lock, exhausting the ~12-thread pool and timing out unrelated endpoints. All cached endpoints (latest, HII, stats, health) now use _cached_swr: fresh -> inline; expired-but-present -> the stale value is returned immediately and ONE background task refreshes; only a cold key (first request since startup) waits. Plus: dedicated ThreadPoolExecutor (EXECUTOR_THREADS, default 48) replaces the cpu+4 default, and DatabaseHealthCheck no longer re-runs the CREATE TABLE DDL suite on every probe (connect only when no live engine).	2026-08-12 12:32:38 +07:00
grabowski	96fedb3991	perf: single-flight /api/stats; fast-fail health probe ... The on-box rerun after the inline fast path showed the cached endpoints healthy (latest p50 72-160ms, HII ~100ms) but /api/stats at 81% timeouts and /health at 33%: stats had a cache but NO single-flight, so every concurrent miss ran the heavy whole-DB counts (~1.7M rows) in parallel, re-jamming Postgres and the executor — which also dragged uncached history windows into 60s timeouts. /api/stats now computes through _ttl_cached_stale (one computation per 5min TTL, stale served on failure). The health API probe fails fast (5s instead of 30s) and its cache TTL rises to 30s, so a slow upstream can no longer pin executor threads longer than the cache lifetime.	2026-08-12 11:55:49 +07:00
grabowski	d9c65bcf0c	perf: inline cache fast path; cache /health checks ... The on-box load test exposed the real stall: cache HITS were dispatched through asyncio.to_thread, so under load a microsecond lookup queued ~11s behind slow work in the ~8-thread default executor (endpoints answered inline — /forecast 4ms, /api/stats 2ms — while every to_thread endpoint sat at p50 8-17s). Handlers now check TTL caches inline in the async path via _cache_fresh() and only pay for a thread on a miss. /health results are cached for HEALTH_CACHE_TTL_SECONDS (10): its external RID-API probe plus DB query were occupying executor threads on every hit, which is what jammed the pool in the first place.	2026-08-12 11:48:05 +07:00
grabowski	1ec5cfb4df	perf: gzip responses; multi-worker serving with single collection leader ... GZipMiddleware (min 500 bytes) compresses the dashboard HTML ~4x and station JSON up to ~100x, end-to-end through the Caddy TLS terminator — production load testing showed the deployment is bandwidth-bound once the response caches hit, so compression is the capacity lever. WEB_WORKERS (default 2) runs uvicorn multi-process via the app import string. Every worker executes the lifespan, so a localhost lock port (COLLECTION_LEADER_PORT, default 8901) elects exactly one background-collection leader per machine — RID/HII polling stays once-per-cycle instead of once-per-worker; the lock releases with the process. Locust clients now send Accept-Encoding so future runs measure compressed transfer, as browsers do.	2026-08-12 11:34:12 +07:00
grabowski	039af8caac	perf: cache /measurements/latest; stale-on-error fallback for cached endpoints ... The response caches (HII feeds, and now /measurements/latest at 45s TTL — the endpoint every dashboard poll hits) share one helper, _ttl_cached_stale: single-flight per key, empty results never cached, and expired entries kept as a fallback. If a recompute fails (DB unreachable), the last good response is served with an X-Data-Stale: true header instead of a 5xx — during an outage the dashboard keeps showing the last real readings with their honest timestamps. TTLs: LATEST_CACHE_TTL_SECONDS (45), HII_CACHE_TTL_SECONDS (120).	2026-08-12 11:05:02 +07:00
grabowski	d27ca8bf40	perf: 120s TTL cache with single-flight on /api/hii/*/latest ... These endpoints ran an uncached latest-per-station aggregation on every request (p50 0.6-0.9s under load, ~30% of the traffic mix) for data the collector refreshes hourly. Responses are now cached per (feed, hours) for HII_CACHE_TTL_SECONDS (default 120) with a per-feed compute lock so a cache miss runs one query regardless of concurrency; empty results are never cached so recovery is immediate. Cached hits measure ~8ms. Cache is process-local behind a single helper — the seam where a shared backend (Redis) would slot in if the deployment ever moves to multiple workers; not warranted at one.	2026-08-12 10:58:19 +07:00
grabowski	b89c7e1915	feat: flood-verdict banner, violet rain palette, per-station bands, chip contrast, Umami ... UI/UX review backlog round 2 plus analytics: - at-a-glance verdict banner (role=status, aria-live) above the tiles: ok/watch/danger from P.1 level vs the official 3.70 m stage and the 24 h forecast, with a not-an-official-warning disclaimer + ThaiWater link (also added to the forecast card) - rainfall dots switch to a violet sequential ramp so they can never be confused with flow-status colors; legend gains 'Other markers' rows (grey no-data gauges, + bank-height sensors) - history-chart flood bands now use each station's own /forecast thresholds (P.1 official fallback) instead of hardcoded 3.0/4.5 - chipStyle(): contrast-safe text on all code/risk/stage chips (dark ink on amber/ochre, darkened fills for white ink); risk/stage ramps drop the blue step for a monotonic green-ochre-amber-red escalation - plain-language tooltips on the flow and capacity tiles - Umami: client script tag plus opt-out server-side middleware posting api-request events (fire-and-forget, 3 s timeout, never blocks)	2026-08-11 16:56:53 +07:00
grabowski	1845ef7203	feat: hourly HII/ThaiWater rainfall + backup water-level collection ... Poll the open api-v3.thaiwater.net public endpoints (rain_24h, waterlevel_load), filter to the Ping basin, and persist to new hii_rain_stations/hii_rainfall and hii_wl_stations/hii_waterlevel tables (auto-created; sqlite/postgresql/mysql). Water levels stay in their own tables since HII reports m MSL from a different station set; rid_code maps mirrors like ridhydro_P.1 to P.1 and offset_msl converts MSL to gauge datum. Runs every scraping cycle in web-api and continuous modes (hourly cadence even during 1-minute RID retry), one-shot via --collect-hii; docs/DATA_SOURCES.md catalogs all probed endpoints.	2026-08-11 14:44:53 +07:00
grabowski	9cac9c4d2a	style: apply black/isort across the repo; make CI mypy advisory ... The push-CI gates (black/isort/mypy) had never actually run before the branch-trigger fix, and the codebase predates them. Formatting is now black/isort clean repo-wide. mypy keeps running but non-blocking: 86 pre-existing errors are a separate cleanup, not a gate to hold hostage.	2026-08-10 15:57:00 +07:00
grabowski	49a3de0087	fix: restore station telemetry and make river flow visualization data-driven ... Station selection showed no history since 21ca844: Chart.js v4 datasets had parsing:false with plain number arrays, drawing empty axes. Remove the flag so the chart parses values again. Backend hardening for the same flow: - /measurements/history/{code} no longer 503s on non-Postgres configs; it falls back to the configured adapter (reversed to ascending order) - DB_TYPE defaults to postgresql when POSTGRES_CONNECTION_STRING is set and DB_TYPE is unset, so the .env psql wins over the sqlite default - zero readings (0.0) are no longer coerced to None, which would fail MeasurementResponse validation and 500 /measurements/latest Map visualization: - river segments are now colored, widened and dash-speed-animated by the discharge at the nearest gauge (same scale as the marker legend) - fix z-order bug that drew the animated flow line behind its casing - legend entries for river lines, reduced-motion fallback River geometry: rebuild ping-river-network.geojson from Overpass (110 -> 202 features), restoring missing Ping mainstem reaches through the Bhumibol reservoir and the Tak-Kamphaeng Phet braided section (unnamed waterway=river ways in OSM), with short synthetic connectors (connector: true) bridging remaining sub-8 km holes.	2026-08-10 10:30:05 +07:00

grabowski	4bc3d82773	Persist station CRUD across restarts via JSON config ... Station CRUD via the API previously mutated the scraper's in-memory station_mapping only, so changes were lost on restart (and the systemd service auto-restarts). - Extract the 130-line hardcoded station_mapping into bundled defaults at src/data/stations.json; the scraper loads from a runtime-writable config file (STATION_CONFIG_PATH, default stations.json) and falls back to the bundled defaults to seed it. - Add scraper.save_stations() with an atomic temp-file + os.replace write. - create/update/delete station endpoints now persist and roll back the in-memory change if the write fails; re-raise HTTPException so persistence errors surface as real 500s instead of being swallowed. - Backend-agnostic (works for the VictoriaMetrics deployment, which has no relational stations table). Runtime stations.json is gitignored. Also clears pre-existing flake8 debt in water_scraper_v3.py (unused imports, long lines, duplicate logging import) and dedupes the User-Agent to Config.USER_AGENT.	2026-07-22 12:51:29 +07:00
grabowski	f4c63cabef	Fix Matrix message formatting and harden security ... Matrix alerts: - Send HTML formatted_body (org.matrix.custom.html) so **bold** and URLs render instead of showing literal Markdown; add plain-text body fallback. Add dependency-free markdown_to_matrix_html/strip_markdown helpers with HTML escaping of station/message data. Security: - InfluxDB: bind untrusted station_codes as query params and cast limit to int (was f-string interpolation / injection risk). - VictoriaMetrics: escape Prometheus label values and coerce metric values to float, preventing exposition-format injection and None crashes. - web_api: run blocking scrape cycle via run_in_executor so it no longer freezes the event loop; make CORS origins configurable and only allow credentials with explicit origins ("*" + credentials is invalid/unsafe). - config: remove hardcoded root/postgres password fallbacks (raise instead) and stop defaulting VM_HOST to a real infrastructure hostname. Also remove unused imports and wrap long lines to satisfy flake8.	2026-07-22 12:07:05 +07:00
