- 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
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.
This commit addresses two major areas:
1. Crash Prevention & Error Handling:
- Added error handling to all database queries to prevent crashes
- Implemented circuit breaker pattern for APRS-IS connection
- Added timeouts to all Redis operations (5 second timeout)
- Fixed unsafe pattern matches that could cause MatchError crashes
- Added try/rescue blocks around background tasks
- Improved socket operation error handling with proper cleanup
- Enhanced packet cleanup worker with comprehensive error handling
2. RF Path Station Markers:
- Fixed issue where digipeater/iGate icons weren't shown when searching for callsigns
- Now loads and displays position markers for all stations in the RF path
- Extracts RF path stations from tracked callsign packets
- Fetches latest position for each digipeater/iGate
- Properly displays complete RF path visualization with station positions
Technical details:
- Added Process.alive? checks before sending messages
- Fixed resource cleanup in terminate functions
- Added proper error handling to File.read operations
- Implemented safe wrapper for ShutdownHandler health checks
- All changes ensure the app continues running even when errors occur

- Fixed File.read crash in devices_seeder.ex with proper error handling
- Added timeout to TCP connect in aprs_is_connection.ex (10s timeout)
- Fixed unsafe socket send operations with error handling
- Added Process.alive? check before sending to PIDs in streaming_packets_pubsub.ex
- Fixed stream materialization memory issue in packet_consumer.ex
- Added error handling for datetime parsing errors
- Prevented crashes from dead processes and closed sockets
These fixes ensure the application is more resilient to:
- Missing files
- Network timeouts
- Dead processes
- Closed sockets
- Invalid data parsing
