- 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)
Parse ADIF tagged-data format with fuzzy frequency-to-band matching
(nearest microwave band for any freq >= 900 MHz). Supports STATION_CALLSIGN,
OPERATOR, CALL, GRIDSQUARE, MY_GRIDSQUARE, FREQ, BAND, QSO_DATE, TIME_ON.
Same dedup and preview/commit flow as CSV upload.
Also fix select dropdown text alignment in daisyUI.
