Adds Microwaveprop.Radio.TextSanitizer to remove BOM, zero-width
spaces/joiners, C0 control bytes (except CR/LF/TAB), and DEL, and to
collapse NBSP and other unicode whitespace into a regular space.
CSV: applied to the whole upload at the top of preview/2.
ADIF: applied per-field-value after extraction so the byte-counted
length tags still slice the right substring.
Operators want a place to jot observations that aren't captured by
the structured fields — weather anecdotes, propagation mode
commentary, equipment details, band conditions. Add a text column
on contacts plus the two ingest paths users submit through:
* /submit single-contact form gets a 3-row textarea under the
other fields. Optional, max 2000 chars, with a live length cap
via maxlength. Whitespace-only input collapses to NULL so the
column reflects "no notes" rather than an empty string.
* CSV importer recognises a `notes` (or `note`) column via the
existing header_aliases table and flows values straight through
submission_changeset. Sample template gets a matching example
row with embedded commas so the quoted-field round-trip is
exercised on download.
ADIF import and the refinement/refinement-notify paths are out of
scope — users specifically asked for CSV + single-contact. Tests
cover the changeset (accept/blank/over-length), CSV header parsing
(plain + RFC-4180 quoted), and LiveView form submit end-to-end.
Contacts can be marked private at submit time (single form, CSV
import, ADIF import) and edit time. Private contacts are hidden
from the public map, the public /u/callsign profile, and the
browse table for anonymous and non-owning viewers. The original
submitter and admins see them inline on the browse table with a
"Yes" badge, and the detail page shows a lock icon. Non-authorized
viewers get a 404 on the detail page.
apply_valid_rows only matched {:ok, _} and {:error, %Changeset{}}, so when
Radio.create_contact returned {:error, :duplicate, existing} — the race
window where preview flagged a row as new but another writer inserts the
same contact before the worker picks up the chunk — the reduce callback
crashed with FunctionClauseError. Oban retried the chunk, rolling back
the Postgrex transaction and surfacing the DBConnection errors the
operator was seeing.
Treat :duplicate as a silent skip: the row is already in the DB, there
is nothing to insert, and the counter should not double-count the existing
contact as an error either.
For large CSVs (e.g. the 34k-row ARRL dump), the synchronous commit
path blocked for minutes and a crash mid-commit left no audit trail.
Refactor to run inserts + enrichment enqueues via Oban.
- New import_runs table: stores preview rows + running counters (total,
processed, imported, refined, error) + status + errors map + timing.
- New :contact_import Oban queue (limit 4) + ContactImportWorker.
Args: {import_run_id, offset, limit}. Each chunk (100 rows) inserts
its slice via CsvImport.commit_rows/1, atomically increments counters
in one update_all, flips status, and broadcasts progress on
'csv_import:<id>' PubSub topic.
- CsvImport.commit_rows/1 extracted from commit/1 (back-compat preserved).
New CsvImport.enqueue/2 persists the run + dispatches N chunk jobs.
Also: submit page copy updated from '902 MHz and up' to '50 MHz and up'
matching the band allowlist expansion done earlier.
LiveView UI for /imports/:id is a separate commit.
Widen dedup match to 4-char grid prefix so an upload with a longer grid
(e.g. FN42aa25) finds the existing FN42 contact. Within a match, classify
as a refinement when the upload strictly extends the existing grid or
fills a missing mode; as a contradiction (still skipped) when grids or
modes genuinely disagree. Refinements flow through a new preview bucket,
update the existing row in place, and re-enqueue enrichment when the
position changed.
The /contacts LiveTable export produces a 12-column CSV with label-style
headers (Station 1 / Grid 1 / QSO (UTC) / ...) in a different column
order plus extras (id, distance_km, hrrr_status, flagged_invalid,
inserted_at). The old positional import rejected it with "expected 6 or
7 columns, got 12".
Replace the positional parser with header-driven mapping:
- Parse the header row, normalize each cell (downcase + trim), and look
it up in an alias map that covers both the raw field names and the
export labels.
- Required columns: station1, station2, grid1, grid2, band, qso_timestamp
(mode stays optional). If any are missing the header, return
{:error, {:missing_required_columns, [...]}}.
- Unknown columns are silently ignored so the export's extras don't break
round-trip.
- Per-row validation stays the same (changeset errors still reported by
row number).
Existing 6- or 7-column positional CSVs that already have a header still
work — the header parser recognizes `station1`, `station2`, etc.
directly.
Profile page:
* New MicrowavepropWeb.UserProfileLive at /u/:callsign is a public
page showing a user's contacts and beacons. Resolves case-
insensitively so /u/w5isp and /u/W5ISP are the same thing; unknown
callsigns redirect to /. Uses daisyUI card / stats / table
components with an avatar-placeholder initial and hero icons.
* Accounts.get_user_by_callsign/1 (case-insensitive) plus
Radio.list_contacts_for_user/1 and Beacons.list_beacons_for_user/1
back the page. Beacons list includes both approved and pending so
owners see their drafts.
* The top nav bar and the three LiveView sidebars (MapLive,
WeatherMapLive, ContactMapLive) now render the logged-in callsign
as a navigate link to /u/:callsign instead of a static label.
* Nine new tests cover the lookup, the LiveView render, and the
ownership-scoped queries.
Flexible band input:
* New Microwaveprop.Radio.BandResolver module converts any of:
ADIF wavelength labels ("33cm", "1.25cm", "6mm", case/whitespace
insensitive), numeric frequency strings ("903.100", "10368.000"),
and canonical MHz integers into the one of the site's known bands.
Returns the nearest allowed band for numeric inputs >= 900 MHz,
nil otherwise.
* 902 MHz is added to Contact.@allowed_bands, ContactEdit.@allowed_bands,
AdifImport.@allowed_bands, and the BandResolver list so "33cm"
round-trips end-to-end.
* AdifImport and CsvImport now delegate band resolution to
BandResolver, and Radio.create_contact/2 normalizes the :band attr
on the way in so the manual form and any API callers benefit too.
CsvImport's "invalid band" tests previously used 99999 MHz which
the new resolver snaps to the nearest allowed band; swapped to
"notaband" which is truly unresolvable.
Contacts and beacons list UX:
* Remove the "Submitted" column from /contacts — it duplicated info
already visible on the detail page and was pushing the real
columns off narrow viewports. submitted_cell/1 and its three
column-specific tests go with it.
* Hide the Lat / Lon columns from /beacons — six decimal places of
coordinates weren't useful next to the grid square and took a
disproportionate amount of row width.
- 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
- 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
Uploads now show a review page with three summary cards (valid,
duplicates, invalid), tables for invalid and duplicate rows, and a
sample of the first 20 valid rows. Nothing is written to the database
until the user clicks "Looks good — submit N contacts".
Duplicate detection treats two rows as the same contact if they share
the same pair of (callsign, grid) tuples (direction-agnostic), the
same band, and timestamps within 60 minutes. Dedup runs against both
existing DB contacts (single band/time-scoped query) and earlier rows
in the same upload, and the preview labels which side matched.
CsvImport grows preview/2 + commit/1; the old import/2 is kept as a
thin backward-compat wrapper that skips dedup. Added 11 new CsvImport
tests and reworked the SubmitLive CSV tests for the two-step flow.
- Add timex ~> 3.7, downgrade gettext to ~> 0.26 for compatibility
- Parse ISO 8601, US dates (M/D/YYYY), AM/PM, 24h, compact formats
- 22 tests covering all accepted timestamp formats and edge cases
- Integration tests for CSV import with US date and space-separated formats
Parse US dates (6/15/2024 2:30 PM), 24h (06/15/2024 14:30),
dashes (06-15-2024 14:30), compact (20240615 1430), date-only
(2024-06-15), and ISO 8601 — all normalized to UTC before insert.
Adds a tabbed UI with single-contact form and CSV upload. Users can
download a sample CSV, upload their file, and get partial import with
per-row error reporting. Enrichment jobs enqueue for each imported contact.
