From 509f271eac00184f74e45d4b71f281f245d2601b Mon Sep 17 00:00:00 2001 From: Graham McIntire Date: Thu, 19 Feb 2026 14:11:39 -0600 Subject: [PATCH] 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 --- TODO.md | 35 +-- assets/js/app.js | 87 ++++---- assets/js/hooks/info_map.js | 8 +- assets/js/map.ts | 10 +- assets/js/map_helpers.ts | 12 ++ config/config.exs | 4 +- lib/aprsme/application.ex | 13 -- lib/aprsme/aprs_is_connection.ex | 196 ----------------- lib/aprsme/is/is.ex | 8 + lib/aprsme/packet_consumer.ex | 55 +++-- lib/aprsme/packet_producer.ex | 35 ++- lib/aprsme/packets.ex | 2 +- lib/aprsme/workers/packet_cleanup_worker.ex | 183 ++++++++-------- lib/aprsme_web/channels/mobile_channel.ex | 4 +- lib/aprsme_web/live/map_live/data_builder.ex | 3 +- .../live/map_live/display_manager.ex | 8 +- .../live/map_live/historical_loader.ex | 14 +- lib/aprsme_web/live/map_live/index.ex | 61 +----- lib/aprsme_web/live/map_live/map_helpers.ex | 68 ------ test/aprsme/aprs_is_connection_test.exs | 204 ------------------ test/aprsme/is_test.exs | 36 +++- test/aprsme/packet_consumer_test.exs | 81 +++++++ .../live/map_live/map_helpers_test.exs | 33 +-- 23 files changed, 400 insertions(+), 760 deletions(-) delete mode 100644 lib/aprsme/aprs_is_connection.ex delete mode 100644 lib/aprsme_web/live/map_live/map_helpers.ex delete mode 100644 test/aprsme/aprs_is_connection_test.exs diff --git a/TODO.md b/TODO.md index 4566c4c..575fe5c 100644 --- a/TODO.md +++ b/TODO.md @@ -2,33 +2,34 @@ ## APRS-IS Connection -- [ ] Consolidate `AprsIsConnection` and `Aprsme.Is` into a single implementation — two separate APRS-IS clients with different reconnection strategies and error handling is a maintenance burden -- [ ] Validate APRS-IS server login response — neither implementation checks if the server accepted the login (wrong credentials or invalid filter syntax goes undetected) -- [ ] Add APRS-IS login response validation — server sends `# logresp` line indicating accept/reject -- [ ] Cap circuit breaker half-open recovery — transition from `:open` to `:half_open` is passive (only happens on call), not automatic +- [x] Consolidate `AprsIsConnection` and `Aprsme.Is` into a single implementation — removed `AprsIsConnection` (was dead code opening a second useless APRS-IS connection) +- [x] Validate APRS-IS server login response — added `dispatch("# logresp " <> rest)` clause that logs unverified vs accepted login +- [x] Add APRS-IS login response validation — server sends `# logresp` line indicating accept/reject +- [~] Cap circuit breaker half-open recovery — assessed: the passive transition is the standard pattern; `get_state` checks elapsed time before every `call`, so recovery is always timely.
