[Bug 198232] Re: file reports negative size for QCOW images
Attached find essentially the same debdiff I sent to Debian; it just has the version number in it changed, and the changelog entry refers to the Launchpad bug number rather than the Debian one. Apart from that, it's the same patch. As I said on the Debian bugtracker, I ran into two non-critical issues. First, the backing-file name isn't stored in a NUL-terminated format; pretending that it's NUL-terminated seems to work, but since I couldn't figure out how to specify a string length based on an indirect value, it's not being done the *right* way. Second, The offset to the backing- file name in qcow2 images is a 64-bit quantity, but there's no way to put in a 64-bit offset. I cheated and assumed that the top four bytes are zero; this works on newly-created images, at least, though I can't guarantee that it'll work in the general case. ** Attachment added: Debdiff against 4.26-2. http://launchpadlibrarian.net/21946270/198232-qemu.debdiff -- file reports negative size for QCOW images https://bugs.launchpad.net/bugs/198232 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This seems to have gotten worse. The output is now: test.qcow: Qemu Image, Format: Qcow , Version: 1 , Disk Size could be: 0 * 256 bytes The number reported for disk size does not vary with the actual size of the image. qcow2-format images don't have any estimated size reported at all. This is file 4.23-2 downloaded from the Intrepid repository and running on Gutsy.
