From b6e9b1ba4e84850746332d74a2a9488e7ce34ae6 Mon Sep 17 00:00:00 2001 From: DoSun Date: Wed, 20 May 2026 14:11:30 +0800 Subject: [PATCH 1/4] fix: prevent Linux csc cloud commands from hanging Fixed the root cause of Linux csc cloud commands hanging by addressing spawn() call issues, not network/permission problems: - Changed stdio from "inherit" to ["ignore", "inherit", "inherit"] to close stdin and prevent blocking - Removed duplicate ensureCsCloud() call that was unnecessary since runCsCloud already calls it - Added disconnect event handler for better error handling - Added explicit detached: false option The real issue was that stdin inheritance caused the spawn call to block on Linux, even when the cs-cloud binary already existed and worked fine when called directly.

This helps verify that arguments are passed correctly when debugging cloud hang issues.
