From: Andrew Au Date: Mon, 23 Feb 2026 16:51:46 GMT Subject: [PATCH 0/1] Fix zombie children when git is PID 1 in containers Message-ID: <20260223165147.3294516-1-cshung@gmail.com> When git runs as PID 1 inside a container and exits via exit(128) on transport errors, child processes (git-remote-https, ssh, proxy) are never waited on because the normal cleanup paths (disconnect_helper, finish_connect) are bypassed. Since PID 1 has no parent to reap its children, these become zombies that persist for the container's lifetime. This patch registers atexit handlers in transport-helper.c and connect.c to ensure children are reaped on any exit path, and clears them on the normal cleanup paths to avoid double-waiting.
