v2: - Fixes a number of bugs in corner cases. - Uses a 1M block size to fetch from the underlying plugin. This improves performance considerably. I also tested this much more thoroughly and can't find any more bugs. Rich.

CentOS 6 has libguestfs-devel 1.20.11, which predates the support in guestfs_add_drive_opts() for requesting an nbd drive instead of a local file (annoyingly, guestfs documentation merely states the function was available since 0.3, without saying which later releases added new options); causing a compilation failure during 'make check'. Maybe the guestfs plugin should still be built,

Matt asked if xz should really be a filter rather than a plugin. The answer is yes, of course it should be! That's been something in the todo file for a while. The commit converts the xz plugin code into a filter (leaving the plugin around, but deprecating it). plugin: nbdkit xz file.xz filter: nbdkit --filter=xz file file.xz plugin: # can't be done filter: nbdkit

FYI; I'm going to push this because it's such an obvious fix. Rich.

There is a small test provided. I tested this a lot more locally and it seems pretty robust. Rich.

I've posted some of these patches or ideas before; but now I'm confident enough with the series that it should be ready to push; at any rate, I can now run test-socket-activation in a tight loop without triggering any crashes or hangs. With this in place, I'm going back to work on making the nbd forwarder wort with the parallel thread model. Eric Blake (8): sockets: Use

Two (not related to each other) refactorings: Patches 1-12 split configure.ac into smaller files using the m4_include mechanism. Patches 13-15 split out parts of guestfs.pod (ie. guestfs(3)) into three new manual pages: guestfs-hacking(3) - how to extend and contribute to libguestfs guestfs-internals(3) - architecture and internals guestfs-security(3) - security and CVEs Patch 16 is a

This has already been pushed upstream. I am simply posting these here so we have a reference in the mailing list in case we find bugs later (as I'm sure we will - it's a complex patch series). Great thanks to Eric Blake for tireless review on this one. It also seems to have identified a few minor bugs in qemu along the way. Rich.

Also available here: https://github.com/rwmjones/nbdkit/tree/2020-windows-mingw-nolib After a lot of work I have made the port to Windows work without using a separate library. Instead, on Windows only, we build an "import library" (library of stubs) which resolves references to nbdkit_* functions in the main program and fixes up the plugin, basically the first technique outlined in
