Remaining: 40 refactoring opportunities (complex/nested functions)
Structs don't implement the Access behaviour, so packet[:received_at]
doesn't work. Use pattern matching to handle Aprsme.Packet structs
separately with dot notation, and use Map.get for regular maps.
This fixes the UndefinedFunctionError when rendering tracked callsign
information with Packet structs from the database.
When packets go through Phoenix LiveView serialization, map keys can be
converted from atoms to strings. Add get_received_at/1 helper that handles
both formats to prevent KeyError when accessing received_at field.
This fixes the crash when the iOS app searches for callsigns and the
LiveView tries to render the tracked callsign's last seen time.
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.
When APRS connection is disabled (in test environment), the LiveView should
show 'disconnected' status instead of hardcoded 'connected'. This fixes the
failing aprs_status_test.
Add get_initial_connection_status/0 helper that checks the
disable_aprs_connection config to set the appropriate initial status.
- 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.
iOS app was sending queries with trailing carriage returns, causing
search failures. Add String.trim() to both search_callsign and
subscribe_callsign handlers to strip whitespace and control characters.
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.
- Add info-level logging to all mobile websocket handle_in callbacks to track
incoming messages (subscribe_bounds, update_bounds, search_callsign, etc.)
- Create LogFilter plug to exclude K8s healthcheck requests from Phoenix logs
- Filter logs for /health, /ready, and / endpoints to reduce noise from
continuous healthcheck probes
- Configure Plug.Telemetry to use custom log level function
This eliminates noisy healthcheck logs while providing better visibility
into mobile websocket API usage.
Mix.env() is not available in production releases, so we need to check
the repo's pool configuration at runtime instead. In test, the pool is
Ecto.Adapters.SQL.Sandbox which doesn't support CONCURRENTLY, so we
skip index creation. In production/dev, indexes are created normally.

The migration was timing out in CI because CONCURRENTLY cannot run
inside transactions (required by the test sandbox). Now the migration
skips index creation entirely in test mode, which is fine since the
test database has no data.
In production, indexes are still created with CONCURRENTLY to avoid
table locking.

The packets table has been truncated so index creation will be fast.

- 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.

Implements comprehensive callsign search and live tracking:
- search_callsign: Search for callsigns with wildcard support
- "W5ISP" finds W5ISP and all SSIDs (W5ISP-1, W5ISP-9, etc.)
- "W5ISP-9" finds only that specific SSID
- "W5ISP*" finds all callsigns starting with W5ISP
- subscribe_callsign: Subscribe to live updates for a callsign
- Loads historical packets for the callsign
- Receives real-time streaming updates
- Supports wildcard patterns
- Works with or without geographic bounds
- unsubscribe_callsign: Stop tracking callsign
When both bounds and callsign are subscribed, packets are filtered
by both criteria (callsign AND within bounds).

Replace 'with' clause that was failing when socket.assigns[:subscribed]
returned nil. Now properly checks subscription status using Map.get with
a default value of false to prevent WithClauseError.
Fixes error: no with clause matching: nil

When mobile clients subscribe to bounds, the server now loads and sends
historical packets immediately, followed by real-time streaming packets.
This matches the web UI behavior and provides a complete view of APRS
activity in the requested area.
Optional parameters:
- limit: Max historical packets to load (default: 1000, max: 5000)
- hours_back: Hours of historical data (default: 1, max: 24)

Add isNaN() checks in addition to isFinite() to catch NaN values before
they reach Leaflet's polyline renderer. This prevents 'can't access

- Add extractCoordinate helper to recursively extract coordinates
- Handle coordinates that come as nested arrays like [[lat]]

- Create MobileChannel for geographic bounds-based packet filtering
- Add MobileUserSocket for mobile client connections
- Implement subscribe_bounds, update_bounds, and unsubscribe events
- Leverage existing StreamingPacketsPubSub infrastructure

filtered by geographic viewport, with efficient bandwidth usage.

- 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.
