At any rate, given the urgency of getting pull requests for -rc2 in before slamming Peter tomorrow, I'll probably try to touch up the issues Max pointed out and queue it today.

The real code is more complicated, something like: offset = tar.fileobj.tell() + BLOCK_SIZE with open(tar.name, "r+") as f: f.truncate(offset + measure["required"]) convert_image(image, tar.name, offset) check = check_image(tar.name, offset) size = check["image-end-offset"] member = tarfile.TarInfo(name) member.size = size tar.addfile(member) tar_size = offset + round_up(size) tar.fileobj.seek(tar_size) with open(tar.name, "r+") as f: f.truncate(tar_size) I'm not sure it helps qemu developers working on these tests. > >> +out = qemu_img_pipe("measure", "-O", "qcow2", "--output", "json", src_disk) > >> +measure = json.loads(out) > >> +qemu_img_create("-f", "raw", tar_file, str(measure["required"])) > > > > Should this be measure["required"] + 1536? > > The test works without it (because of compression), but yes, if you are > going to test writing into an offset, you should oversize your file by > that same offset.

Thanks Max and Eric. Should I post a fixed version later today?

The closer the iotest is to reality, the more likely it will serve as a good regression test. Cutting corners risks a test that passes in isolation even when we've done something that breaks the overall process in one of the corners you cut. >> >> At any rate, given the urgency of getting pull requests for -rc2 in >> before slamming Peter tomorrow, I'll probably try to touch up the issues >> Max pointed out and queue it today. > > Thanks Max and Eric. > > Should I post a fixed version later today? A v2 would be helpful.
