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.
Right-hand dark sidebar holds the layer selector, description,
navigation links, and auth menu. Mobile floating panel mirrors the
pattern used on /map so users get the same controls in both views.
- Forecast hour clicks showed only a small square of coverage because
:preload_forecast ran at mount using a hardcoded fallback bounding box
instead of the client's actual viewport. Move the preload trigger into
handle_event("map_bounds", ...) so the cache always matches the
viewport the client just asked about.
- Map overlay blinked on load/update because renderScores called Leaflet
GridLayer.redraw(), which removes every tile element before recreating
them. Repaint the existing tile canvases in place instead.
- Prod SMTP to mail.smtp2go.com was failing with an "unexpected_message"
TLS alert: gen_smtp wasn't sending SNI so the wildcard cert endpoint
rejected the handshake. Set tls: :always with explicit tls_options
(server_name_indication, versions, verify).
- AdifImport.normalize_mode/2 maps ADIF MODE (and SUBMODE when present)
onto the fixed set of modes the site accepts: CW/SSB/FM/FT8/FT4/Q65.
SUBMODE takes precedence so `MODE=MFSK, SUBMODE=FT8` correctly imports
as FT8. USB/LSB/DSB all become SSB; NBFM/WFM become FM.
- Unknown modes (RTTY, PSK31, etc.) map to nil so the row still imports
— mode is optional on the submission path now.
- AdifImport.mode_mapping_reference/0 returns the user-facing list of
recognized inputs and their mappings.
- Submit page's ADIF tab renders that list in a table so users can see
upfront what will happen to their file before uploading.
- Add ContactMapController serving /api/contacts/map with pre-gzipped
JSON from Microwaveprop.Cache. Browsers handle Content-Encoding: gzip
natively; payload drops from 5.7 MB raw to 1.5 MB on the wire (73%).
Cache TTL 10 min, invalidated on contact insert alongside the other
contact-map cache keys.
- Move contact map payload out of the LiveView's initial HTML entirely.
Shell renders with the filter chrome (count + band list); the hook
fetches contacts from the HTTP endpoint in parallel with map init.
This also avoids Phoenix.Socket's 64 KB frame limit (push_event would
have required chunked transfer or a global frame size bump).
- Parallelize ContactLive.Show hydrate: five independent DB loads
(weather, solar, hrrr_path, terrain, iemre) now run concurrently via
Task.async + Task.await_many. Total latency drops from sum(each) to
max(each), cutting contact show hydrate time roughly 5x.
- Add Weather.GridCache: ETS cache of derived HRRR grid rows keyed by
valid_time, cluster-synced via PubSub. Eagerly warmed from
PropagationGridWorker after each upsert so /weather map pan/zoom and
weather_point_detail hit zero DB on warm cache.
- Replace latest_weather_grid DB query path with cache-first lookup +
DB fallback. hrrr_profiles is 42M rows partitioned; pulling 3-10k
rows per viewport on every pan was the main cost.
- ContactLive.Show: defer the heavy enrichment loads (weather, solar,
HRRR, terrain, IEMRE, elevation profile, ITU-R propagation analysis,
data_sources) into a handle_info(:hydrate) that runs after the shell
renders. Initial mount now returns nil placeholders; template already
had :if guards for all of them. Shell-to-first-paint goes from
~500ms-2s down to ~20ms.
- Cache fetch_queue_counts for 5s in ContactLive.Show — oban_jobs group
by query was running on every contact page view.
- Backfill stats: wrap count_unprocessed, fetch_stats, fetch_db_stats
in Microwaveprop.Cache with 2-5s TTLs; bump refresh debounce from 1s
to 2s so bulk enrichment events don't thrash the DB.
- Add contacts_inserted_at_desc_id_desc_idx so /contacts list runs as an
Index Scan (~0.4ms) instead of a Seq Scan + top-N heapsort (~77ms on
58k rows)
- Add Microwaveprop.Cache: tiny ETS-backed TTL cache for memoizing
expensive-but-stale-tolerant values
- Cache total_entries for unsearched /contacts page loads (30s TTL,
invalidated on insert)
- Cache the entire /contacts/map payload (pre-encoded JSON + band list),
moving load_contacts into Radio.contact_map_payload; invalidated on
new contact insert. Mount goes from ~150-300ms to ~5ms.
- Fix /map overlay blinking on load: reuse the Leaflet GridLayer across
renderScores calls and just redraw() against the updated ScoreGrid,
instead of removeLayer + new layer which flashed between tile regens
- Make mode optional on submission: schema change (null: true),
submission_changeset no longer requires it, blank strings normalise to
nil, CSV import accepts 6-column (no mode) or 7-column layouts
- core_components .input adds a red asterisk to labels when required,
giving users a visual cue for which fields must be filled on /submit
- ScoreCache stores {band, valid_time} as %{{lat, lon} => score} map so
point lookups are O(1); adds fetch_point/4 and valid_times/1
- available_valid_times/1 reads directly from ScoreCache when warm,
falls back to DB on cold start
- point_forecast/3 iterates cached valid_times and uses fetch_point/4
instead of hitting the DB per click
- NexradCache: node-local ETS cache of decoded n0q PNG pixel buffers
keyed by 5-minute rounded timestamp; skips ~1-5s HTTP+decode on
concurrent/repeat clicks within the same window
- MapLive: start_async the rain_scatter fetch so point_detail renders
immediately with a pending marker; push rain_scatter_update when
NEXRAD resolves
- MapLive: preload all 18 remaining forecast hours for the current
viewport after mount/band change/propagation_updated; client caches
them and renders timeline scrubs instantly without a server roundtrip.
Adds set_selected_time event for fast-path state sync.
- Propagation map JS: forecastCache map + drawScatterMarkers helper,
timeline click uses preloaded cache when available
- Add ScoreCache GenServer with node-local ETS table keyed by
{band, valid_time}, subscribed to "propagation:cache" PubSub topic so
every pod stays in sync with a single hourly compute
- scores_at/3 checks cache first, falls back to DB and populates on miss
- PropagationGridWorker warms and broadcasts the cache for each band
after every forecast hour upsert; prunes >2h old entries
- Replace per-pixel string-keyed Map with flat Int8Array over the CONUS
grid in propagation_map_hook.ts to eliminate allocations in the tile
rasterization hot loop (interpolateScore / propagationReach)
1. Prevent user_id impersonation in contact submissions
- Remove user_id from submission_changeset cast fields
- Pass user_id as a separate server-side argument to create_contact/2
- Client form params can no longer forge account-linked contacts
2. Restrict flag toggle to admins only
- Add admin? guard to toggle_flag event handler
- Hide flag button from non-admin users in template
3. Reset enrichment on timestamp edits
- Add qso_timestamp to the fields that trigger enrichment reset
- Prevents stale weather/HRRR/IEMRE data after time changes
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
- Replace %Struct{} with Struct.t() in all @spec annotations
- Replace length(x) > 0 with x != [] in test assertions
- Fix multi-line spec struct references in weather.ex
The ownership_timeout controls how long a process can hold a checkout,
but the per-query Postgrex timeout (default 15s) is separate. Oban
inline mode chains workers synchronously, so individual queries can
exceed 15s under concurrent test load.
- Revert enrichment status cards from daisyUI stat to plain containers
(tabular status rows don't fit the stat component's layout)
- Add overflow-hidden to DB stat cards for large numbers
- Fix select text centering with display:flex + align-items:center
- Show subsquares (5' x 2.5') at zoom >= 11 with lighter styling
- Pad map bounds by 10% so edge tiles always have score data
- Re-send bounds after 500ms to catch late container layout changes
- Add belongs_to :user on Beacon schema, preload in get_beacon!/1
- Show "Submitted by {callsign}" on beacon detail page
- Add NTMS donation link on the about page
- Change grid preference text to 8 characters (e.g. EM12kp37)
