ConnectionMonitor.gather_cluster_stats was calling :rpc.call(Node.self())
which GenServer.call'd back into itself while blocked in handle_info,
causing a 5-second deadlock timeout every 30 seconds. Fixed by computing
local stats directly from state.
LeaderElection never verified that a leader still held the :global
registration. After :global conflict resolution (two isolated nodes
merging), the loser was silently unregistered but stayed is_leader: true
forever, causing both pods to connect to APRS-IS with the same callsign
in a reconnect loop. Fixed by adding verify_leadership/1 to
check_leadership which detects lost registrations and steps down.
:global.register_name returns :no even when the name is already
registered to the calling PID. This caused the leader to clear its
own leadership state every 5 seconds after cluster formation triggered
a redundant re-election attempt.
Now checks if we already hold the registration before attempting to
re-register, preserving leadership state across cluster topology changes.
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.
When the PacketProducer buffer crosses 80% capacity, signal Aprsme.Is
to switch its TCP socket to passive mode, leveraging TCP flow control
to slow APRS-IS intake. Resume active mode when buffer drains below 30%.
A 30-second safety valve timer auto-resumes if backpressure gets stuck.
Disconnect/reconnect/terminate paths all clear backpressure state.
Remove overly aggressive CSS overrides that set height: auto and
overflow: auto on html/body. These forced the html element to expand
to full content height, preventing the browser's native viewport
scrolling. The browser handles non-map page scrolling correctly by
default — only map pages need explicit overflow: hidden.
Extracts client IP from CF-Connecting-IP or X-Forwarded-For headers
and sets conn.remote_ip before request logging, so K8s logs show the
actual client address instead of the internal cluster/ingress IP.
Use CF-IPLatitude/CF-IPLongitude headers instead of making HTTP calls
to ip-api.com on every page load. Eliminates ~500ms latency, external
API dependency, and flaky tests.
Also disable test server to prevent port conflicts during development.
- Switch PacketProducer buffer from list to :queue for O(1) overflow handling
- Add cached leadership check via :persistent_term to eliminate GenServer.call
bottleneck in packet distribution hot path
- Simplify packets_live coordinate extraction from 70 lines of nested
conditionals to helper functions (extract_coordinate/2, format_coordinate/1)

app.js console.logs)
- Remove sobelow dependency (false positives blocking commits)
- Add 25 new tests for PacketProducer, coordinate helpers, and cached leadership
- Handle login send failure in AprsIsConnection instead of crashing
- Close leaked sockets on login failure in Aprsme.Is (init + reconnect)
- Keep rescheduling keepalive timer when disconnected to prevent permanent loss
- Use supervised BroadcastTaskSupervisor instead of unsupervised Task.start
for packet broadcasting
- Remove racy Process.alive? check in StreamingPacketsPubSub; send/2 to
dead PIDs is a no-op, :DOWN monitors handle cleanup
- Add dateline wrapping to SpatialPubSub.point_in_bounds? matching
StreamingPacketsPubSub behavior
- Add bad_packets table cleanup to PacketCleanupWorker
- Add TODO.md with remaining improvements
Users could register duplicate callsigns with different casing (e.g.,
"w1aw" and "W1AW") because the database unique index was case-sensitive.
Additionally, live validation showed false "already taken" errors on
every keystroke.
Changes:
- Add case-insensitive unique index using lower(callsign)
- Skip callsign uniqueness validation during live form changes
- Add test verifying case-insensitive uniqueness enforcement
- REST API: Fix id type from integer to UUID, add device/equipment
fields, correct rate limiting info (100 req/min, not "none"),
add 429 status code
- Mobile API: Fix search_callsign response field (lon not lng),
add path to packet fields, correct rate limiting/timeout docs,
clarify update_bounds behavior
- Fix flaky pipeline tests (async race on global Application config)
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
- Fix PacketCleanupWorkerTest to use relative timestamps based on
configured retention period rather than hardcoded 365-day assumption
(was failing when PACKET_RETENTION_DAYS env var is set to a small value)
- Fix capture_aprs.py to use timezone-aware datetime.now(timezone.utc)
instead of deprecated datetime.utcnow()
- Add bad_packets.txt to .gitignore
- Add mix task aprs.parse_file
- Add minimum movement threshold (100m) to skip stationary stations
- Add max hop distance (10km) to break trails at igate-hopping artifacts
- Require 3+ points per segment to filter noise from 2-point jumps
- 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
- Initialize :aprsme ETS table in application.ex with message_number
counter; was missing, causing crash in Is.send_message/1
- Trigger reconnect on gen_tcp.send failure instead of leaking the
dead socket with active timers
- Remove cluster-only env vars from deployment (POD_IP, POD_NAME,
POD_NAMESPACE, RELEASE_DISTRIBUTION, RELEASE_NODE) since
CLUSTER_ENABLED=false
- Remove redundant APRS_PASSCODE secret ref now that APRS_PASSWORD
is set as plaintext
- Add missing env vars to migration init container (PHX_HOST, PORT,
APRS_PORT, APRS_CALLSIGN, APRS_PASSCODE) so runtime.exs config
provider doesn't fail due to Kubernetes service discovery injecting
APRS_PORT as a full URL
- Guard ConnectionMonitor.accepting_connections?/0 with Process.whereis
to avoid crashing when the GenServer isn't started (e.g. cluster
enabled but no libcluster topologies configured)
