Create a virtual FAT-formatted floppy disk from a directory of files. For example: nbdkit floppy /path/to/directory The implementation of this is quite different from nbdkit-iso-plugin since we cannot use an external program. Instead this plugin synthesizes the MBR partition and FAT32 structures that are required. To do: Implement bootable virtual floppy using syslinux. This is not

These plugins have in common that they store either a list of allocated strings or a list of constant strings. Define either string_vector or const_string_vector as appropriate and use it to store these lists. --- plugins/iso/Makefile.am | 1 + plugins/split/Makefile.am | 1 + plugins/floppy/virtual-floppy.h | 7 +++-- plugins/floppy/directory-lfn.c | 35 +++++++++-------------

Add nbdkit-floppy-plugin, “inspired” by qemu's VVFAT driver, but without the ability to handle writes. The implementation is pretty complete, supporting FAT32, LFNs, volume labels, timestamps, etc, and it passes both ‘make check’ and ‘make check-valgrind’. Usage is simple; to serve the current directory: $ nbdkit floppy . Then using guestfish (or any NBD client): $ guestfish --ro

Annotate some function parameters with attribute((nonnull)). Only do this for internal headers where we are sure that we will be using sufficiently recent GCC or Clang. For the public header files (ie. include/nbdkit-*.h) it may be that people building out of tree plugins are using old GCC which had problems, or even other compilers that don't support this extension at all. Libvirt has an

v1 was here: https://www.redhat.com/archives/libguestfs/2019-January/msg00008.html In v2 I have provided two patches: The first patch extends attribute((nonnull)) to most internal functions, but not to the external API. The second patch uses a macro so that attribute((format)) is only used in the public API on GCC or Clang. At least in theory these headers could be used by a C compiler which

This was a rather longer trip around the houses than I anticipated! The basic purpose of the patch series is to set $nbdkit_stdio_safe to "0" or "1" in sh and eval plugin scripts. To do that, I ended up adding a nicer way to manipulate environ lists, and to do that, I ended up adding a whole generic vector implementation which is applicable in a lot of different places.

I like this change. I think we were overloading the config_complete method before to do two different things (complete configuration; do any allocation/housekeeping necessary before we can start serving). The only questions in my mind are whether we want this before 1.18, and whether the name ("get_ready") is a good one. Rich.
