Hi, when I tested building nbdkit 1.1.15 in a current Debian chroot, I ran into the following test failure. A repeated build went fine through the tests and so far I have not been able to reproduce it with the previous version. The failing build was done using a clean Debian/sid, amd64 chroot spawned by sbuild. Cheers, -Hilko FA...

This works OK on x86_64, but fails on our fast new Amberwing (aarch64) machine. I've attached the test-suite.log file, but I'm not very sure what's going wrong from that.

Remove the need to use file= (and in future other) parameters for many plugins. eg. Using the file plugin becomes: nbdkit file disk.img Rich.

This incomplete patch adds a new filter allowing more control over when nbdkit exits. You can now get nbdkit to exit gracefully on certain events, such as a file being created, a pipe held open by another process going away, or when another PID exits. There is also a script option to allow for completely custom events. It is untested at the moment, I'm posting it to ge...

tmpfs has a known bug of O(n^2) behavior with lseek(SEEK_HOLE); this is one situation where the noextents filter can come in handy to avoid the performance penalty of exposing accurate extents.

v1 was here: https://www.redhat.com/archives/libguestfs/2018-September/msg00024.html v2: - As discussed in the patch review, tighten up the characters permitted in keys. - Update documentation to note that relative paths can be made safe by prefixing with ./ and absolute paths do not need any extra steps. - I pushed patch 1/6 from the v1 series since it was just a trivial

This essentially turns the whole of nbdkit into a library. There is a rump nbdkit program left which simply contains a main() function that forwards to the nbdkit_main() function in the library. The reason for this is to allow nbdkit to be compiled on Windows, because Windows does not allow shared libraries to contain any undefined symbol...

...name under our control requires either a separate namespace via dlmopen() (which itself is annoying - it messes up gdb debugging), or that the override occur prior to any other library that also depends on -ldl. Which means that if we are going to provide this functionality, we have to do so from nbdkit proper. Note that properly injecting a dlopen shim for all subsequent shared library loads requires that the override itself be in a shared library. Thus, nbdkit has to pull it in via a shared library link, rather than merely a .o file, and we now have to install something in pkglibdir. What'...
