From c5aa0e1f4269a42168262e1bc23d279d68b93c5d Mon Sep 17 00:00:00 2001 From: Matt Johnson Date: Sun, 2 Aug 2026 01:34:15 +0000 Subject: [PATCH] Fix event-loop starvation, MeshCore stability, config-page hardening - mesh_data_store.py / env/store.py: make refresh() async, offload blocking polls via asyncio.to_thread/gather so 7 lockstep sources no longer starve the shared event loop. - main.py: gather pollers concurrently + set_default_executor thread pool. - Dockerfile / docker-compose.yml: healthcheck now curls the dashboard for a real liveness signal instead of a process-exists check. - transport/meshcore_transport.py: MeshCore keepalive loop (get_time() every 120s), reconnect re-arm (_post_reconnect_setup_async from _on_connect_event), and MC channel-name normalization (_resolve_mc_channel_idx strips a leading #). - dashboard-frontend: MeshCoreConnection.tsx config-page hardening, new ErrorBoundary component, wired into App.tsx. - tests: fix ~40 call sites broken by refresh() becoming async ( test_generic_http.py, test_store_received_delta.py, test_store_wzdx_persist.py) by wrapping with asyncio.run(), matching this suite's existing convention for calling async code from sync test functions. Verified: all 40 tests pass.
