- 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 object name regex only matched [A-Z0-9 ] which missed names with
hyphens (P-K5SGD), hash symbols (#146.760), and other printable ASCII.
Changed to .{9}[*_] to match all valid object names including killed
objects. Also merged the two cond branches so data_extended is tried
first with information_field parsing as fallback.
Removed dead copy_insert/3 tests from db_optimizer_test.
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.
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.
- 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)
- Remove debug logging from hot paths (packets.ex queries, PacketDistributor,
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
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
- 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)
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

- Fix length/1 check in mobile_channel.ex
- Add LeaderElection alias in connection_manager.ex
All warnings and design suggestions now complete!
Remaining: 40 refactoring opportunities (complex/nested functions)
Check if Repo process is started before attempting to collect PostgreSQL
metrics. This prevents the 'could not lookup Ecto repo' error message
during application startup when the periodic metrics collector runs
before the Repo is fully initialized.
The metrics collection now silently skips when the Repo isn't ready
and will succeed on subsequent runs once the Repo is started.
- Add Phoenix.LiveViewTest import to ConnCase to fix warnings
- Disable AppSignal in dev and test (only enable in prod)
- Explicitly disable clustering in test environment
- Fix PacketDistributor to check cluster_enabled before calling LeaderElection
- Add Phoenix.CodeReloader listener to mix.exs
This prevents tests from trying to call cluster-specific GenServers
(ConnectionMonitor, LeaderElection) that don't exist in test mode.
The host from Application.get_env returns a binary string, but :gen_tcp.connect
expects a charlist. This was causing ArgumentError on connection attempts.
Convert host to charlist if it's a binary before passing to :gen_tcp.connect.
- Fix unsubscribe_from_bounds -> unsubscribe (function doesn't exist)
- Fix search_callsign query to use 'lon' instead of 'lng' field
- Add comprehensive test suite for mobile channel:
- Join and subscription tests
- Bounds validation tests
- Callsign search tests
- Callsign tracking tests
- Streaming packet tests
- Packet data format tests
- 29 tests total, all passing
Created test/support/channel_case.ex for channel testing infrastructure.

- Always use ETS-based RateLimiter instead of checking for REDIS_URL
- Remove RedisRateLimiter calls that were causing crashes
- Simplify wrapper to only delegate to Aprsme.RateLimiter
- Replace Cachex with native ETS (Erlang Term Storage) in Cache module
- Remove Redis-based caching logic from application.ex
- Always initialize ETS tables for device_cache, query_cache, symbol_cache
- Update StatusLive to use Aprsme.Cache instead of Cachex directly
- Fix crash on startup when REDIS_URL was set but Redis not used
This fixes the no_cache error that was causing pods to crash.
Previously, when clustering was enabled, the leader election process
would wait indefinitely for the cluster to form. If cluster formation
failed or took too long, no leader would be elected and the APRS-IS
connection would never start, leaving the system disconnected.
Changes:
- Add 30-second timeout for cluster formation
- Force leader election after timeout, even in single-node mode
- Add election_forced flag to prevent duplicate election attempts
- Improve logging to distinguish between cluster and single-node modes
This ensures that at least one node will always connect to APRS-IS,
even if clustering fails completely.
