From 936d0142d540d3099196d385dd82df5b79fddf0d Mon Sep 17 00:00:00 2001 From: Jamie Pine Date: Fri, 3 Oct 2025 22:01:47 -0700 Subject: [PATCH] fix: Resolve infinite loop and improve graceful disconnect handling in networking service - Implemented duplicate detection in ConnectionLost handler to prevent infinite reconnection loops. - Introduced a 2-second delay before reconnection attempts to avoid tight loops. - Added Goodbye message to notify connected devices during graceful shutdown, reducing disconnection detection time from 3 minutes to ~500ms. - Enhanced error handling to ensure proper state management during disconnections. --- INFINITE_LOOP_FIX.md | 331 +++++++++++++++++ PERSISTENT_CONNECTION_FIX.md | 344 ++++++++++++++++++ core/src/service/network/core/event_loop.rs | 173 ++++++--- core/src/service/network/core/mod.rs | 240 ++++++++++++ core/src/service/network/device/mod.rs | 15 +- core/src/service/network/device/registry.rs | 16 +- .../src/service/network/protocol/messaging.rs | 36 +- .../network/protocol/pairing/initiator.rs | 27 +- .../network/protocol/pairing/joiner.rs | 26 +- 9 files changed, 1085 insertions(+), 123 deletions(-) create mode 100644 INFINITE_LOOP_FIX.md create mode 100644 PERSISTENT_CONNECTION_FIX.md diff --git a/INFINITE_LOOP_FIX.md b/INFINITE_LOOP_FIX.md new file mode 100644 index 000000000..3162a0c66 --- /dev/null +++ b/INFINITE_LOOP_FIX.md @@ -0,0 +1,331 @@ +# Infinite Loop & Graceful Disconnect Fix + +## ๐Ÿ› Issues Fixed + +### 1.
