From 182ecc0e5322f8cff43278ed8f5fdd4456184c1c Mon Sep 17 00:00:00 2001 From: Roo Code Date: Tue, 26 Aug 2025 22:47:49 +0000 Subject: [PATCH] fix: handle race condition for compound commands in new terminals - Add compound command detection to identify commands with &&, ||, ;, |, & operators - Implement delay mechanism for compound commands on newly spawned terminals - Ensure shell integration is fully attached before executing compound commands - Improve error handling in TerminalRegistry for race conditions - Add comprehensive tests for compound command handling Fixes #7430 ---
