Although it [attempts](https://gitlab.com/qemu-project/qemu/-/blob/1a2d52c7fcaeaaf4f2fe8d4d5183dccaeab67768/chardev/char-stdio.c#L52) to restore stdin to blocking mode, it misses that stdout also gets O_NONBLOCK by [qemu_chr_open_fd](https://gitlab.com/qemu-project/qemu/-/blob/1a2d52c7fcaeaaf4f2fe8d4d5183dccaeab67768/chardev/char-stdio.c#L116) ([here](https://gitlab.com/qemu-project/qemu/-/blob/1a2d52c7fcaeaaf4f2fe8d4d5183dccaeab67768/chardev/char-fd.c#L215)). It causes the next applications in the script misbehave because they get unexpected EAGAIN on write to stdout. -Steps to reproduce: -Run the following script: - -``` -#!/usr/bin/env bash - -qemu-system-x86_64 -nodefaults -display none -no-reboot -serial stdio & -PID="$!" -sleep 5 -kill "$PID" -wait "$PID" -echo "EXITING $?" - -sleep 5 -seq 1 400000 -``` - -The seq command will be interrupted prematurely: - -``` -... -5143 -5144 -5145⏎ wResource temporarily unavailable -write: Resource temporarily unavailable -write: Resource temporarily unavailable -``` - -When run from fish shell, it will also start misbehaving when running next commands (fish bug report: https://github.com/fish-shell/fish-shell/issues/10600). -Additional information: -Expect a patch from me soon. |
