security.yml previously ran safety/bandit/semgrep with `|| true` and could
not go red. Now: pip-audit on requirements.txt is a hard gate (dev deps
reported only), bandit HIGH fails (B104 bind-all skipped: intended behind
Cloudflare/Caddy), pip-licenses uploaded as a report. Weekly + on
dependency/source changes.
Running it locally found 29 advisories, all in pinned-and-forgotten
runtime deps: starlette 0.27 (7, incl. Host-header path confusion and
form DoS), fastapi 0.104, requests 2.31 (3), pymysql 1.1. Bumped to
current: fastapi 0.141.1 / starlette 1.6.0, pydantic 2.13.5, uvicorn
0.52.4, requests 2.34.2, pymysql 1.2.0; dev: pytest 9.1.1, black 26.5.1.
pip-audit is now clean. requires-python narrowed to 3.11 (the truth:
psycopg2-binary 2.9.9 fails on 3.13; pandas 2.0.3 has no 3.12 wheels).
Full suite passes; API smoke-tested (health, stations, forecast, history,
stats, docs, openapi) on the new stack. black 26 reformatted 8 files.
The Test Suite job failed on every push since the black check was added
because the tree had never been formatted, and pre-commit said 120
columns while CI ran black's default 88. pyproject.toml now carries
[tool.black] / [tool.isort] (88, black profile) as the single source;
pre-commit reads it; `make format` applied it (13 files, whitespace only,
146 insertions / 128 deletions, tests unchanged at 146 passed).
ci.yml: lint (black, isort, flake8 hard errors) + pytest. The Docker
registry push, VictoriaMetrics integration test, staging/production
deploy and Apache-Bench jobs were template scaffolding for hosts and
registries that do not exist; production is a systemd unit updated by
git pull. Removed rather than left permanently skipped.
docs.yml: the "Check markdown links" step curl'd every URL in every .md
and failed on localhost examples and the Tailscale IP, and the Sphinx
jobs built artifacts nobody read. Replaced by two checks that mean
something: relative links/images in README, CONTRIBUTING and docs/
resolve inside the repo, and the FastAPI OpenAPI schema exports with
the documented endpoints present (uploaded as an artifact).
New SQLAdapter.get_database_stats() aggregates totals, station count,
date range, and hourly-slot coverage in one query per dialect. The
endpoint follows the existing 503-guard/to_thread/TTL-cache pattern;
the dashboard gains a five-tile stats strip on the existing refresh
cadence. Coverage denominator is hour-truncated so off-hour endpoints
cannot push it past 100%; MySQL slot expression avoids % characters
that would break under pyformat bind interpolation.
Gap detection is now hour-granular: days with partial data (missing
hourly slots) are re-fetched, not just days with no rows at all. The
API's hour-24-is-next-midnight quirk is handled by re-fetching day D-1
when day D is missing its 00:00 slot. SQL adapters gain single-query
range and recorded-hours lookups; non-SQL backends fall back to the
old day-granular check.
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.
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.
- MeasurementResponse.discharge is now Optional[float]; measurements with a
null discharge no longer raise a Pydantic ValidationError (HTTP 500) on the
/measurements/latest and /measurements/station endpoints.
- InfluxDB save_measurements guards float(discharge) against None instead of
crashing with TypeError.
- Extract the duplicated measurement->response mapping into a single
_to_measurement_response helper used by both measurement endpoints.
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.
