Graham McIntire	871620223d	Performance improvements, code cleanup, remove sobelow ... - 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	2026-02-19 14:51:01 -06:00
Graham McIntire	509f271eac	Improve packet pipeline reliability, security, and cleanup efficiency ... - Fix XSS vulnerability in buildPopupContent fallback (escape callsign/comment) - Add batch insert retry with individual fallback in PacketConsumer - Add APRS-IS login response validation (logresp dispatch handler) - Fix stale generation check bypass in HistoricalLoader - Replace two-step SELECT+DELETE cleanup with single CTE-based batch DELETE - Change default packet retention from 365 to 7 days - Delete MapHelpers (100% duplicate of CoordinateUtils + BoundsUtils) - Delete AprsIsConnection (dead code, second unused APRS-IS connection) - Fix InfoMap hook memory leak (store/cancel setTimeout ref) - Extract singleton loadMapBundle with callback queue in app.js - Extract @heat_map_max_zoom constant in DisplayManager - Add telemetry to cleanup worker and PacketProducer buffer overflow - Track PacketProducer buffer_size as integer for O(1) length checks - Remove duplicate bounds functions from index.ex	2026-02-19 14:11:48 -06:00
Graham McIntire	a7d934cb5b	Fix APRS-IS connection, packet pipeline, and cleanup reliability ... - 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	2026-02-19 13:34:10 -06:00
