Three-factor compound failure causing chat sessions to silently stall: 1. Silent Exception Death (helpers/defer.py): DeferredTask._on_task_done() captures exceptions in Future but no code reads it. Chat sessions die with zero UI feedback. Fix: Log exceptions and notify AgentContext on task failure. 2. O(n²) Per-Chunk DirtyJson Parsing (agent.py): stream_callback runs extract_json_root_string() + json_parse_dirty() on EVERY streaming chunk with growing string length. Fix: Only parse when full.rstrip() ends with } or ]. 3. Indefinite History Compression Wait: organize_history_wait has await task.result() with no timeout. Fix: Wrap with asyncio.wait_for() 30s timeout. Amplifier: All chats share one EventLoopThread singleton, making concurrent sessions particularly affected. |
