fix(code): keep chat input responsive during /restart - #4808
Merged
Conversation
`_handle_restart_command` awaited the multi-second `_restart_server_manual` (`server_proc.restart()`) directly on the Textual message pump, so key events stopped being forwarded and the chat input froze until the restart finished. Run the respawn as a detached `asyncio.create_task` (mirroring the MCP viewer/force-reconnect paths) so the pump stays free and typing lands while the restart is in-flight.

…#4808) Typing in the chat input is no longer blocked while the `/restart` command respawns the server. --- Running `/restart` froze the chat input until the server finished respawning. `_handle_restart_command` awaited the multi-second `_restart_server_manual` (`server_proc.restart()`) directly on the Textual message pump, so key events stopped being forwarded and the chat input was "blocked". This is the same class of bug fixed for the MCP viewer `Ctrl+R` reconnect path in langchain-ai#4753 — the fix runs the respawn as a detached `asyncio.create_task` (mirroring the MCP viewer/force-reconnect paths), keeping the pump free so keystrokes stay live and queued messages drain once `ServerReady` fires.
