Run as root, SUDO_USER is unset and uv is not on root's PATH, so the training environment was not synced. Now the sync runs as the owner of .venv, with uv from PATH, that user's ~/.local/bin or ~/.cargo/bin, /usr/local/bin, or UV=/path/to/uv.
Phase 4 of docs/RUST_REWRITE.md. Since 2026-10-18 ping-collector (rust/)
collects, forecasts, notifies (ntfy + Matrix) and serves the website/API;
nothing in production ran the Python service code any more.
Removed (~17k lines): the FastAPI app (web_api, schemas, health_check,
metrics, postgres_history, forecast_history, thaiwater), the Python RID
collector and CLI (water_scraper_v3, main, run.py), the notifier and Matrix
alerting (notify, alerting), the multi-backend adapters (SQLite, MySQL,
InfluxDB, VictoriaMetrics) with demo databases, models/validators/exceptions/
logging/rate limiter, ml/skill.py (served by Rust now), the migration tooling
(api_parity, collector_parity, e2e_notify, install_collector.sh,
gen_notify_cases.py, spikes/rust-forecast), Docker/compose/Grafana files,
sql/, the release workflow and the docs for all of that. Their tests went
with them.
Kept in Python: src/ml (training, evaluation harness, export; predict.py as
the reference the Rust forecaster is tested against), the HII and RID-dam
clients/stores for the archive backfills (their live collectors removed),
the backfill scripts, retrain.sh + timer, forecast_parity.py.
- PostgreSQL only: src/config.py is database_url() from POSTGRES_* / .env;
the stores lost their sqlite/mysql branches (and the 2026-08 column
migration). The database tests run against a throwaway schema from
TEST_DATABASE_URL (tests/conftest.py pg_url, skipped without it), as the
Rust tests do; CI gets a PostgreSQL service. 100 tests (66 without a DB).
- The notifier settings moved from src/notify.py into src/ml/export.py;
flood_config.json regenerates byte-identical.
- tests/test_dashboard.py checks every path the dashboard fetches against
ping-collector's router.
- Dependencies: fastapi, uvicorn, pydantic, influxdb, pymysql, psutil,
schedule, sphinx, pyinstaller, mypy, pytest-asyncio dropped; python-dotenv
1.1.1 explicit (it came in through uvicorn[standard]).
- Formatting contract extended to scripts/ and tests/ (reformatted once).
- scripts/install.sh is the one installer (fresh host or update, in place in
a checkout without touching its ownership): binary, units, uv sync, .env
defaults, removes the retired water-monitor.service and any old
--alert-check cron job, dry run + forecast check, restart, readiness wait.
- Docs, CLAUDE.md, CONTRIBUTING.md, .env.example, Makefile, unit comments
and Rust doc comments updated to the Rust service.
train_all() now raises RainUnavailableError when use_rain=True and the
Open-Meteo history cannot be loaded, instead of logging a warning and
writing gauge-only (v2) bundles over the deployed v3 set -- which is what
the 2026-09-01 server retrain did unnoticed. --no-rain remains the explicit
way to get v2. CLI exits 2 with a one-line error. Three tests cover the
guard, the opt-out, and the v3 happy path.
scripts/retrain.sh trains into models/.staging, refuses to promote unless
metrics.json shows hgb-v3+ and >=14 trained stations, then renames bundles
into place (previous generation kept in models/.previous). No API restart:
predict.py reloads by mtime on the hourly precompute.
water-monitor-retrain.{service,timer}: 1st of each month 03:30, Persistent,
OMP_NUM_THREADS=4, Nice=15, same sandbox as the API unit. install.sh now
does `uv sync` into .venv (one env rule; removes a stale venv/) and enables
the timer. water-monitor.service in the repo matched neither the deployed
unit nor the uv env; it now does (run.py --web-api, .venv, EnvironmentFile).
- .env now chmod 0600 and APP_DIR chmod 0750 after chown, so the Matrix token
and DB credentials are not world-readable.
- uv auto-install (curl | sh as root) is now opt-in via AUTO_INSTALL_UV=1 and
pins a specific uv version; otherwise the script requires uv to be
pre-installed and fails with instructions, avoiding unattended remote code
execution as root.
- scripts/install.sh: one-command hardened deploy (creates the water-monitor
system user, deploys to /opt, builds a uv-managed venv, installs and enables
the systemd unit). Idempotent; excludes .env/*.db/stations.json from sync so
runtime state is preserved.
- Fix placeholder Documentation= URL in water-monitor.service.
- README: document the script as the primary systemd install path, with manual
steps kept as a fallback.
