- Update .tool-versions to elixir 1.20.0-otp-29 / erlang 29.0.1
- Update all hex dependencies
- Remove unused aliases in path_compute.ex and rover_planning_live/show.ex
- Fix Oban unique states to include :suspended (use :incomplete group)
Replaces per-QSO-endpoint asos_batch granularity with per-station-day
granularity. Each contact in the same UTC day near the same station
now produces identical unique-args and collapses to ONE Oban job, so
the backlog shrinks as cross-contact duplicates dedup.
Each fetch also covers a full 24h window (vs the previous 4h) so one
IEM request returns ~24 hourly observations instead of ~1-2. The
effective bytes-per-request is 10x higher, amortizing the
IemRateLimiter gap + 429 retry tail across far more data.
Changes:
- Weather.station_day_covered?/2 + station_day_pairs_covered/1 — cheap
UTC-day coverage checks for the enqueuer + worker skip paths.
- WeatherFetchWorker gains an "asos_day" clause that fetches the full
UTC day for one station and upserts. Skips if the day is already
covered in the DB.
- ContactWeatherEnqueueWorker.build_asos_jobs/3 now emits one asos_day
job per (station_id, UTC date) pair. ±2h windows crossing midnight
enumerate both dates.
- Microwaveprop.Weather.RebatchAsos.to_day_jobs/1 migrates any
already-queued asos/asos_batch jobs into the new shape. Idempotent;
supports dry_run.
- asos_batch worker clause retained for jobs already in flight at
deploy time.
2835 tests + credo green.
IEM's ASOS CSV endpoint accepts multiple station= params in a single
request. Prior code enqueued one WeatherFetchWorker job per nearby
station per QSO endpoint — N jobs × 1 station each — which paid the
IemRateLimiter's 1500ms gap and the IEM 429-retry tail N times per
contact.
Changes:
- IemClient.asos_url/3 accepts a list of station codes.
- IemClient.fetch_asos_batch/3 fetches N stations in one call and
returns rows grouped by station_code (with absent codes filled as
empty lists so callers can stub them).
- parse_asos_csv/1 now exposes the station_code column it was
previously discarding.
- WeatherFetchWorker gains an "asos_batch" fetch_type clause that
unpacks rows per (station_id, station_code), upserting or stubbing
each. The single-station "asos" clause stays for already-queued
retryable jobs.
- ContactWeatherEnqueueWorker.build_asos_jobs/3 now emits one batch
job per (lat, lon, 4h window) covering every uncovered nearby
station (sorted for deterministic unique-args).
Expected effect on backfill: ~10-20x fewer IEM requests per contact
enrichment cycle, matching drop in 429 retry traffic.
StatusLive had a hand-rolled thousands-separator format_number/1 and a
binary-prefix format_bytes/1 — duplication that was already part of the
review punch-list. Move both to Microwaveprop.Format (which previously
held only distance_km) and delete the local defps. Fourteen call sites
switched to Format.number / Format.bytes.
Also extend the IEM error classifier to snooze on Req.TransportError
{:closed, :timeout, :econnrefused, :nxdomain}. Same rationale as the
429 snooze in batch 1: upstream TCP resets mid-fetch aren't a job
failure, they're transient — returning {:error, _} blows them up into
Oban.PerformError logspam with full stacktraces.
Batched from a system-wide review pass.
**Rate-limit + transient-error log hygiene**
- WeatherFetchWorker: classify IEM HTTP 429 as {:snooze, 300} instead
of {:error}. Stops Oban.PerformError stack-trace spam on every
routine rate-limit during backfill, keeps the retry semantics.
- IonosphereFetchWorker: compress GIRO TLS :unknown_ca error from a
~400-char inspect blob to 'TLS unknown_ca (CA bundle missing)'.
- FreshnessMonitor: log only when an enqueue actually lands (the
Oban unique conflict case was silently dropping jobs but still
producing 'enqueuing grid worker' info lines every 5 minutes).
**Perf**
- Rust grid_level_keys(): pre-format 'TMP:{p} mb' / DPT / HGT keys
once via OnceLock instead of format!()'ing per-cell. Removes ~3.6M
String allocations per f01..f18 chain step across pipeline.rs,
hrrr_points.rs. Same for the wgrib2 :(TMP|DPT|HGT): pattern in
hrrr_points.process_batch (sfc_pattern / prs_pattern OnceLock).
- MapLive preload_forecast: Task.async_stream with max_concurrency=4
replaces the 18-wide Enum.map serial walk. Forecast cache warms
~4× faster after a band change, with ordering preserved.
- grid_tasks: partial composite index on (run_time DESC,
forecast_hour ASC) WHERE status='queued' AND kind='forecast',
matching the Rust claim query's ORDER BY. Drops the old
status-only partial that forced a sort per claim.
**Correctness**
- ContactImportWorker: add Oban unique:[keys: [:import_run_id,
:offset]]. Was missing on a worker whose perform() does a
non-idempotent atomic counter increment — a retry would double-
count imported rows.
- CommonVolumeRadarWorker: x_min..x_max default step is -1 when
x_min > x_max, triggering a runtime deprecation warning. Force
Range.new(_, _, 1) explicitly.
**Cleanup**
- Drop unused tmp_dir parameter from hrrr_point_worker + its
process_batch signature.
IemClient.fetch_asos returns 24-288 rows per station per call, each
previously triggering an individual UPDATE-conflict round-trip via
Weather.upsert_surface_observation/2. On the Turing Pi 2 Postgres
node that per-row latency dominates ingestion time.
Add Weather.upsert_surface_observations/2, a bulk variant that collapses
the rows into a single Repo.insert_all with the same
update-only-when-changed on_conflict predicate and (station_id,
observed_at) conflict target. Switch WeatherFetchWorker to use it.
Contact detail now searches for soundings in progressively wider radii
(150 → 300 → 600 → 1000 km) before declaring "No soundings found".
When even 1000 km turns up nothing, enqueue WeatherFetchWorker RAOB
jobs for every station at the widest non-empty radius. The worker
passes the contact_id through so it can PubSub back to
contact_enrichment:<id> as each sounding lands, and the LiveView
rehydrates without a refresh.
Also adds Weather.soundings_with_widening_radius/1 and
ContactWeatherEnqueueWorker.enqueue_raob_fetch_with_widening/1 so the
same logic can be reused from other callers.
Both workers had unique: [period: 300] which only dedupes within a
5-minute window. Re-running the enrichment-enqueue script hours or
days later stacked identical jobs in the available queue — we found
~60k redundant weather + 3k redundant hrrr jobs in prod from the
March and April enqueue passes.
:infinity means Oban dedupes against every live job in the states
list regardless of age, so a second enqueue pass is a no-op as long
as the first pass's jobs haven't completed yet.
Aliases: add module aliases for 9 nested module references
Apply: replace apply/3 with direct module attribute calls
Line length: break 1 long spec line
Refactoring: extract helpers to reduce complexity and nesting
in show.ex, radio.ex, weather workers, terrain, duct detection,
backfill dashboard, contact map, and mix tasks
When ASOS/RAOB/IEMRE APIs return empty data, store a stub record so
dedup checks (has_surface_observations?, has_sounding?, has_iemre_observation?)
see coverage and don't recreate the same jobs on future backfill runs.
Backfill dashboard now has checkboxes to select which enrichment types
to process (HRRR, Weather, Terrain, IEMRE). Prevents weather jobs from
flooding the queue when only HRRR needs work.
Removed n_live_tup > 0 filter that hid tables when pg_stats reports 0 rows
during VACUUM. Added dead tuple column with warning highlight to monitor
vacuum progress. Also includes Styler reformatting and unused dep cleanup.
- Only deduplicate against active jobs (available/scheduled/executing/
retryable), not completed ones. Completed jobs no longer block new
inserts for the same args.
- Period reduced from 3600s to 300s
- Fixes contacts stuck in :queued with no actual Oban jobs
WeatherFetchWorker, HrrrFetchWorker, and TerrainProfileWorker now have
unique: [period: 3600] — Oban deduplicates identical jobs within 1 hour.
Repeated page loads won't queue redundant fetches.
- WeatherFetchWorker broadcasts on ASOS and RAOB completion
- Contact show page subscribes and reloads weather data on receipt
- Loading spinners for soundings and surface observations when queued
- Propagation analysis recomputed with new sounding duct data
20 attempts with exponential backoff capped at 6 hours ensures
data is eventually fetched even during extended rate limiting or
API outages (~3 days of retrying before giving up).
IEM was returning 503s under 10 concurrent workers. Three fixes:
- Req transient retry with exponential backoff on IEM requests
- WeatherFetchWorker Oban job retries failed ASOS/RAOB fetches 2-3h later
with random jitter to avoid thundering herd
- Import script concurrency reduced 10→5, weather queue capped at 3
