nbdkit partitioning boot.img swap.img root.img ... creates a virtual disk by adding a partition table. In ancient times Xen used to do this. Rich.

The partitioning plugin patch is the same (except for rebasing). However I have changed the first two patches based on feedback received. In particular this fixes a very serious bug found by Eric Blake in the current truncate filter. Rich.

For v3 I reimplemented this using mke2fs -d. This obviously makes the implementation a whole lot simpler, but cannot support multiple directory merging. Patches 1-3 are the same as before. I've also reproduced the notes from v2 below. v2: - Fix inconsistent tab/space. - All 3 plugins now contain a block of text pointing to the other 2 plugins. - TMDIR -> TMPDIR - Unlink the

Another interesting thing you can do with this plugin: https://rwmj.wordpress.com/2019/02/19/nbdkit-linuxdisk-plugin/ v2: - Fix inconsistent tab/space. - All 3 plugins now contain a block of text pointing to the other 2 plugins. - TMDIR -> TMPDIR - Unlink the temporary file and other cleanups along error paths. - fclose -> pclose, and check the return value for errors. -

Two simple patches which make libnbd compile on FreeBSD. Are we OK to copy common/include/byte-swapping.h from nbdkit? There is no license issue that I know of. Should we put it in lib/ or create a common/ directory? The header file is actually also needed by the tests (follow up patch for that) so putting it in common/ might make more sense. Some notes if you want to compile on FreeBSD: -

Turns out Japanese trains are good for coding! In supermin we have a bunch of code to create the libguestfs appliance. It creates it directly using libext2fs (part of e2fsprogs). We can use the same technique to create ext2 virtual disks in nbdkit, which is what this new plugin does. Why a new plugin instead of modifying the floppy plugin? See the 4/4 commit message for an explanation. The

With these patches, a majority of tests pass. The notable things which are still broken: - Because FreeBSD links /home -> /usr/home, $(pwd) gives a different result from realpath(2). Therefore some tests which implicitly rely on (eg) a plugin which calls nbdkit_realpath internally and then checking that path against $(pwd) fail. - Shebangs (#!) don't seem to work the same way

If we compare the "common" subdirectory between nbdkit @ 6b4178d0fdfe ("ci: Temporarily disable perl in MacOS", 2023-02-27) and libnbd @ d05cd8f384a7 ("Version 1.15.11.", 2023-02-28), we find differences. We can categorize these differences along two (orthogonal) axes: - Intentional or unintentional. Intentional differences are for example when one of the libnbd

Hi, When an integer argument is passed as value, node_set_value segfaults. Reproducer is at the end of this message The backtrace points at hivex-py.c, function get_value. While obj is non-NULL, `bytes = PyUnicode_AsUTF8String (obj);` returns NULL. Kind regards, Peter https://lekensteyn.nl #!/usr/bin/env python3 import hivex, sys h = hivex.Hivex(sys.argv[1]) print(h) val = {
