From 130b406ee2d50b6d55f1d06fd76208029a95072e Mon Sep 17 00:00:00 2001 From: Joe Particle Date: Wed, 16 Jul 2025 06:05:30 +0000 Subject: [PATCH] Fix async bug in D-Bus interface and update documentation - Fixed critical 'asyncio.run() cannot be called from a running event loop' error - Converted all D-Bus methods to async def with proper await usage - Fixed dbus-next integration for full async functionality - Daemon now properly handles concurrent async operations - Updated TODO.md and CHANGELOG.md to reflect async bug fix - Added interface_simple.py with dbus-next implementation - Updated D-Bus policy for development use -
