Hello! After continuous cross-builds [0], and a continuously cross-built QEMU image [1], here’s the next step: continuous GNU/Hurd testing in QEMU.
The ‘qemu_test’ at <http://hydra.nixos.org/jobset/gnu/hurd-master> runs a simple test within QEMU, in a stripped-down QEMU image. Currently, the test consists in unpacking the Hurd tarball, hosted on an smbfs mount, and running ‘configure && make -j4’ [2]. This has already allowed me to find invalid port deallocation errors. The test uses a patched GNU Mach, which makes it fail when such errors happen [3]. In the process, a few bugs got fixed in smbfs [4], which makes it usable. The “large” QEMU image at <http://hydra.nixos.org/job/gnu/hurd-master/qemu_image/latest/download> now has an smbfs translator on /host, so that one can boot it with: qemu-system-x86_64 -smb $PWD disk-image.qcow2 and exchange files between the host and guest machine. Feedback welcome! Thanks, Ludo’.
