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.
- 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
- 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
