Swaps `if`/`cond` branches for multi-clause function heads or head-pattern
matching, making the control flow visible in the function signatures:
- Navigation.determine_map_location: resolve_location/4 now dispatches on
the shape of the geolocation input and whether URL params are explicit.
- Navigation.handle_callsign_tracking: per-case clauses for empty callsign
and explicit-URL-params short-circuits, plus a final clause that does the
DB lookup and rescues once.
- Navigation.handle_callsign_search: dispatch_callsign_search/3 separates
the valid/invalid callsign branches.
- InsertOptimizer.optimize_based_on_performance: pattern-match on
[_, _, _ | _] to require ≥3 samples without calling length/1.
- InsertOptimizer.calculate_insert_options and throughput helpers split
into guarded clauses instead of inline `if`.
- maybe_emit_optimization uses same-var pattern matching to skip the
telemetry hit when nothing changed.
Adds unit tests covering every branch of both modules plus SignalHandler,
LocaleHook, and the InsertOptimizer's :noproc fallback path. Coverage
64.69% → 65.72%.
Every other defstruct in the app already has a @type t declaration;
these two GenServer states were the last holdouts. Declaring t here
means the whole codebase is ready for the typed-struct milestone of
Elixir's set-theoretic type system (the next phase after the inference
pass already shipping in 1.19).
get_recent_packets/1 and get_recent_packets_for_map/1 now accept a
:cursor option (%{received_at: DateTime, id: uuid}) instead of :offset
for deep paging. On the 100M-row partitioned packets table, offset
scanning was linear in page depth; keyset is constant.
Ordering tightened to (received_at DESC, id DESC) so the cursor is
stable across ties. idx_packets_received_desc still covers the lookup;
a dedicated (received_at DESC, id DESC) index isn't worth its size
given microsecond timestamp granularity.
historical_loader migrated from batch_offset*batch_size scheduling to
a sequential cursor chain. The old loader fanned out N Process.send_after
batches up-front which could arrive out-of-order; the cursor version
waits for batch N before scheduling N+1, and also short-circuits the
remaining schedule when an under-full batch signals exhaustion.
mobile_channel load_historical_packets dropped its meaningless
`offset: 0`; callsign history already lacked offset.
No LiveView or WebSocket payload shapes changed. offset: 0 (or omitted)
still behaves as first page; non-zero offsets are silently ignored.
Turned on :error_handling, :underspecs, and :unmatched_returns in
mix.exs dialyzer config. The 97 warnings this surfaced were fixed in
place rather than suppressed:
- unmatched_return (79): explicit discard with `_ = ...` for
fire-and-forget side effects (Process.cancel_timer, :ets.new,
send/2), and pattern-matched `:ok = ...` for control-plane
Phoenix.PubSub subscribe/unsubscribe/broadcast calls so a future
return-shape change fails loud.
- contract_supertype (18): tightened @spec arg and return types on
data_builder, historical_loader, url_params, packet_utils,
encoding_utils, aprs_symbol, weather_controller, packet_replay to
match each function's actual success typing.
No behavioural change. mix compile clean, 1008 tests pass, dialyzer
count is now 0.
If build_packet_data raises, the :weather_callsigns_cache process-dict
entry would stick around and poison subsequent unrelated calls on the
same LiveView process. Wrap the building pass in try/after so the key
is always removed.
- packet_consumer: when a batch exceeds max_batch_size, carry the
excess over to the next cycle instead of dropping it. Previously
any overage was split off into a drop list that was only logged,
losing packets the producer had already acknowledged.
- map_live: cancel the hover_end_timer in terminate/2 so a user
disconnecting while a marker is still highlighted doesn't leave
an orphaned timer behind.
- packet_consumer: rescue/log exceptions inside the async broadcast
task so PubSub serialization bugs or outages are observable
instead of silently killing the Task.
- prepared_queries: swap ST_Y/ST_X BETWEEN predicates for the && /
ST_MakeEnvelope pattern so bounds queries hit the GIST index on
packets.location instead of sequentially scanning.
Drop the pre-insert aprs_messages broadcast in Is.dispatch (subscribers
already get a richer payload via postgres:aprsme_packets after insert).
Switch PacketsLive.CallsignView to the per-callsign packets:<CS> topic
so it only receives relevant packets instead of filtering every one.
In PacketConsumer: reuse the received_at stamped in Is.dispatch instead
of calling DateTime.utc_now/0 per packet; drop the duplicate struct_to_map
pass (Is.dispatch already handled it); fold coordinate validation and
Geo.Point construction into set_lat_lon + create_location_geometry so
coords are normalized once; extract device_identifier from the already-
normalized attrs; pre-build the broadcast payload once (identifier pick,
lat/lon aliases, routing callsign) so the async broadcast task no longer
does Map.drop/Map.merge per packet.
Rewrite PacketSanitizer.sanitize_packet / sanitize_data_map with Map.new/2
instead of Enum.reduce + Map.put — one allocation per packet instead of N.
Also compute has_weather in Packet.changeset/2 so direct-changeset inserts
(tests, backfills) populate it the same way the GenStage pipeline does.
Dep upgrades (mix deps.update --all):
- phoenix_live_view 1.1.27 → 1.1.28
- swoosh 1.23.1 → 1.25.0
- bandit 1.10.3 → 1.10.4
- credo 1.7.17 → 1.7.18
- hammer 7.2.0 → 7.3.0
- igniter 0.7.6 → 0.7.9
- and minor: fine, lazy_html, meck, mimerl
- removed stale lock entries: geocalc, gettext_pseudolocalize, gridsquare
Bug fixes surfaced during update:
- ETS cache tables were :protected (owned by Application master), preventing
the Cache GenServer from writing; change to :public + write_concurrency
so device/symbol/query caches actually work
- historical_dot_html returned Phoenix.HTML.safe tuple instead of plain string;
symbol_html is JSON-encoded for JS so it must be binary
- String.slice always returns binary so the || "Unknown error" fallback was
unreachable dead code (dialyzer guard_fail)
- Supervisor.which_children always returns a list so the _ -> branch in
database_metrics was unreachable dead code (dialyzer pattern_match_cov)
- Add @type t :: %__MODULE__{} to User schema to resolve unknown_type in user_auth spec
- Extract nested if in leader_election to fix Credo nesting depth violation
- Update .dialyzer_ignore.exs: remove 2 stale entries, add false positives for
Ecto.Multi/Gettext opaque types and Mix.Task PLT limitations
Increase long-poll fallback timeout to 5s for mobile networks, add
visibility change listener for proper reconnection on app foreground,
and remove backdrop blur that stalls network operations on iOS Safari.
Only the 7 SVGs actually used are vendored into priv/heroicons/.
Also fixes the icon component path resolution (was missing the 24/
size directory) and corrects hero-x-mark/hero-map-pin icon names
that included an erroneous hero- prefix.
- Modified handle_zoom_threshold_crossing to detect tracked_callsign
- Show trail line instead of heat map when tracking at zoom ≤ 8
- Maintain heat map behavior when not tracking
- Maintain marker behavior at zoom > 8
- Filters packets by tracked callsign and time threshold
- Sorts packets chronologically by received_at
- Pushes show_trail_line event with coordinates
- Returns socket unchanged when no packets found
Make the map and panel CSS default to "sidebar open" on desktop
(>= 1024px) without requiring the slideover-open class. Only the
slideover-closed class now hides the sidebar. This prevents a blank
gap when the map and panel states get out of sync after LiveView
reconnects.
- Strip Mic-E telemetry from comments before database storage
- Show sender callsign on map labels instead of object names for clarity
- Object names still used for grouping to maintain trail organization
- Add comprehensive tests for new encoding utilities
Fixes display issues where weather balloon "X3234025" was shown
instead of station "WA0YMH", and Mic-E telemetry bytes like "!w>`!"
were appearing in comments.
Dark navbar header with radio icon, refined slideover control panel
with branded header and section cards, polished cards/tables/badges
on info, packets, and about pages using ring borders and shadow-xs.
Drop 10 dead parser-compat columns (srccallsign, dstcallsign,
origpacket, body, header, alive, posambiguity, symboltable,
symbolcode, messaging) and move 14 display-only columns into a
single `data` JSONB column (PHG, telemetry, radiorange,
information_field, format, posresolution, position_ambiguity,
luminosity, rain_midnight).
Reduces row width from ~70 to ~48 columns. Table is ephemeral
so migration uses DROP/recreate. Also fixes snow_24h -> snow bug
in weather check query and adds null byte stripping for JSONB
string sanitization.
- Extract prepare_markers_for_push/2 to reduce nesting depth in
handle_info
- Split detect_item_or_object into smaller predicate and application
functions to reduce cyclomatic complexity
- Coerce Decimal/nil values to native numbers in telemetry metrics
(PostgreSQL sum() returns numeric type mapped to Decimal by Postgrex)
- Align locate button horizontally with zoom controls
- Remove CSS `bottom: 50px !important` on popups that pushed them too
high above markers
- Hide trails when markers are clustered (zoom < 11) so trails don't
point to invisible markers inside cluster bubbles
- Fix locate button overlap with zoom controls and keep it always
light mode
- Remove duplicate slideover/toggle CSS from layout files (single
source of truth in component)
- Remove dead CSS classes and standardize breakpoints to 1024px
- Add isDestroyed guards on async callbacks to prevent race conditions
- Escape callsigns in marker HTML to prevent XSS
- Replace Leaflet _container private API with getContainer()
- Clean up about page placeholder text
- Replace N+1 get_latest_packet_for_callsign calls in RF path loading
with single get_latest_packets_for_callsigns batch query (DISTINCT ON)
- Change batch packet processing to collect marker removal IDs and push
one remove_markers_batch event instead of individual remove_marker calls
- Add callsignIndex reverse map (callsign_group → Set<markerID>) for O(1)
lookup in new_packet/new_packets handlers instead of scanning all markers
- Server tracks callsign replacements in prepare_packet_state, sends
convert_to_historical list so JS skips full markerStates scan
- Historical packets get red dot HTML server-side in build_minimal_packet_data
instead of JS createMarkerIcon generating it
- Add callsign_group field to all packet data output; server pre-sorts
by group with chronological order so JS iterates directly
- Normalize heat map intensity in Clustering.cluster_packets (min/50, cap 1.0)
instead of JS doing it per-point
- Remove buildPopupContent JS fallback and unused escapeHtml import;
server already provides popup in all data paths
- Batch real-time packet push_events: collect marker data across the
packet batch and send a single "new_packets" WebSocket message instead
of one per packet. JS handler processes all live→historical conversions
before adding new markers to avoid intra-batch conflicts.
- Batch RF path station queries: replace N+1 get_latest_packet_for_callsign
calls with a single DISTINCT ON query selecting only callsign + lat/lng.
- Add read_concurrency: true to streaming_packets_subscribers and :aprsme
ETS tables (read-heavy, rarely written).
- Remove dead GC code in PacketConsumer (threshold > 1000 unreachable with
max batch_size of 100).
Delete 5 unused modules: Presence (untracked), LiveView ShutdownHandler
(unused mixin), RateLimiterWrapper (pointless delegation), Passcode
(only used by own test), MapLive.Utils (pure delegates).
Fix ShutdownHandler to not call deleted Presence. Inline ParamUtils
at call sites. Remove cachex dep and 27 stale entries from mix.lock.
Clean commented-out Exq/Redis config from application.ex.
System A (PacketManager + PacketStore ETS) had a fatal ID mismatch:
extract_packet_ids returned Ecto UUIDs but PacketStore stored under
MD5 hashes — cleanup could never find stored packets. Unified all
packet tracking on visible_packets map in LiveView assigns.
Deletes packet_manager.ex and packet_store.ex, removes from
supervision tree and PacketDistributor.
Historical map loading previously fetched all 73 columns (SELECT *) from
the packets table (~2068 bytes/row). Added get_recent_packets_for_map/1
with select_map_fields/1 that fetches only the 22 columns needed for map
rendering (~200 bytes/row), yielding a ~3x query speedup.
Also removes unused all_packets tracking from PacketProcessor and
simplifies visible_packets cleanup in Index.
The slideover toggle button now uses a fixed light theme (white bg,
dark arrow) so it's always visible on the map regardless of OS dark
mode. Removed prefers-color-scheme overrides since the button overlays
the always-light map tiles.
Fixed map not resizing when closing the sidebar — the #aprs-map div
has phx-update="ignore" so server-rendered classes never updated.
Now uses LiveView JS commands (JS.toggle_class + JS.dispatch) to
toggle classes client-side and trigger map.invalidateSize(), replacing
the custom push_event/handleEvent JS handler.
parse_rf_path was filtering out all paths containing qA* constructs,
which is virtually every APRS-IS packet. The qA* element delimits the
RF path from the APRS-IS metadata — it should be split on, not
discarded. Now properly extracts digipeaters (before qA*) and the
igate (after qA*), while filtering APRS aliases like WIDE/RELAY/TRACE.
Also adds hover handlers to trail polylines so hovering anywhere on a
call's track shows the RF path, not just on the dot markers.
Replace all DaisyUI component classes with pure Tailwind CSS utility
classes following TailwindUI conventions. Use dark: variants for dark
mode instead of DaisyUI's data-theme semantic color system.
- Remove DaisyUI plugin and theme vendor files
- Configure Tailwind v4 custom dark variant for data-theme attribute
- Migrate all components: cards, tables, badges, buttons, forms,
navigation, dropdowns, modals, alerts, star ratings, spinners
- Update all auth pages (login, register, settings, password reset,
confirmation) to TailwindUI card layout
- Update content pages (about, API docs, status, packets, bad packets,
info, weather) to TailwindUI patterns
- Replace opacity-based text styling with semantic gray colors
- Update test assertions to match new class names
- Remove BodyClassHook: use CSS :has() selectors on data-map-page attribute
instead of JS toggling body.map-page class
- Remove ResponsiveSlideoverHook: pass viewport_width via LiveSocket connect
params and determine initial slideover state server-side
- Convert theme selector from data-set-theme attributes with DOMContentLoaded
listeners to JS.dispatch("phx:set-theme") with a single event handler
- Fix buggy reRenderAllCharts that incorrectly used `new MapAPRSMap()` as a
Map constructor; charts now re-render via themeChanged event directly
APRS object packets (e.g. DAPNET transmitters) were showing the
sender's callsign on the map instead of the object name. For example,
DB0SDA (Germany) sending an object for P-K5SGD (Texas) would display
as "DB0SDA" at the Texas coordinates.
- Add display_name/1 to PacketUtils that returns object_name for
objects, item_name for items, falling back to sender
- Update DataBuilder to use display_name in all callsign display paths
- Fix object/item detection order in packet_consumer to prevent
objects from being incorrectly flagged as items
- Add DataBuilder tests for object/item display name behavior
- Fix flaky PacketPipelineSupervisor test (ensure module loaded)
- Add Packets.get_other_ssids/1 to query other SSIDs for a base callsign
- Show other SSIDs in MapLive sidebar with track and info link buttons
- Clicking an SSID tracks it on the map (zooms, shows marker, updates URL)
- Refactor InfoLive.Show to use shared Packets.get_other_ssids/1
- Remove web-layer dependency from Packets context (no more
AprsmeWeb.TimeHelpers calls from data layer)
- Return raw received_at DateTime instead of pre-formatted timestamp maps
- Format timestamps in the view layer where they belong
- Remove duplicate slideover panel that was hidden behind the controls panel
- Fix toggle button positioning (was rendered above viewport at top:-9px)
- Remove conflicting high-specificity CSS that prevented mobile display:none
- Remove width:100vw on map so it properly resizes when panel opens
- Use theme-aware colors for panel background and navigation links
- Wrap navigation links in proper ul.menu for valid HTML and DaisyUI styling
Replace case/cond/if blocks with multi-clause function dispatch
and pattern matching in function heads across 9 modules:
- WeatherUnits: case to multi-clause unit_system/1, unit_labels via do_unit_labels/1
- PacketUtils: if to pattern match on %{"id" => id}, multi-clause threshold/callsign
- SetLocale: case to multi-clause extract_locale/1
- IPGeolocation: if/cond to pattern match on conn, binary prefix matching for private_ip?
- DeviceIdentification: cond to extracted pattern_matches?/2
- MobileChannel: cond to multi-clause do_callsign_match/2
- PacketProcessor: cond to dispatch_visibility/6 on {in_bounds, has_marker} tuple
- PacketManager: destructure packet_state in heads, multi-clause maybe_cleanup/3
- AprsSymbol: case/if to multi-clause get_table_id/1, normalize_symbol_code/1
