Introduce the concept of a backend. Currently the only type of backend is a plugin, and there can only be one of them. Instead of calling functions like ‘plugin_pwrite’ you call the backend method ‘backend->pwrite (backend, ...)’. The change is largely mechanical. I was able to remove ‘assert (dl)’ statements throughout since we can now prove they will never be called. Note this does not

Socket activation (aka systemd socket activation) is a simple protocol that lets you pass in an opened, listening socket to a server. Supporting socket activation allows you to use a modern superserver to serve infrequent NBD requests without needing nbdkit to be running the whole time. Although the protocol was invented by systemd, it has been implemented in a few other places, and the protocol

Prefer named constants over magic numbers in the 'struct option' list, and expand the list of enums for long-only options so that the call to getopt_long() can switch directly to every option, rather than needing a lengthy if/else chain that grows for every new long option. Patch best viewed with whitespace changes ignored. Signed-off-by: Eric Blake <eblake@redhat.com> ---

For mainly historical reasons we tended to use int to store boolean values. However using bool is probably safer in some corner cases (eg. ?v == true? can fail badly if v is an int, but works for bool). bool was added in C99 so let's use it. --- server/internal.h | 16 +++++------ server/connections.c | 28 +++++++++--------- server/crypto.c | 4 +-- server/main.c | 67

This also defines SOEXT as the extension of shared objects (ie. "so" or "dll"), and uses it everywhere. I assumed this must already be defined by either autoconf or mingw (like OBJEXT) but I cannot find anything except in glib (G_MODULE_SUFFIX).

Even though so far there is just one possible setting to read, isolate in an own function the code to parse a configuration file and read the settings out of it. Now there's a new config_t handle used every time, but since config_read would reset an handle completely, there is no behaviour change. --- fish/config.c | 88 +++++++++++++++++++++-------------------------------------- 1 file

Both plugin.c and filter.c add the same three fields on top of struct backend, and use very similar code in initializing them. Let's stop the duplication, by moving those three fields into struct backend, and creating a new backend.c for manipulating them. In turn, we can drop the backend->name() accessor in favor of just directly accessing the name field. This is a net reduction in

This rather complex feature solves a problem for certain web services that require a cookie or token for access, especially one which must be periodically renewed. For motivation for this feature see the included documentation, and item (1)(b) here: https://www.redhat.com/archives/libguestfs/2020-July/msg00069.html --- plugins/curl/nbdkit-curl-plugin.pod | 142 ++++++++++++

Like with the previous commit, this replaces instances of: if (something_bad) { fprintf (stderr, "%s: error message\n", guestfs_int_program_name); exit (EXIT_FAILURE); } with: if (something_bad) error (EXIT_FAILURE, 0, "error message"); (except in a few cases were errno was incorrectly being ignored, in which case I have fixed that). It's slightly

From: Yifan Gu <gyf304@gmail.com> Windows PE DLL needs function indirection, this patch injects API functions for plugins / filters if on Windows.

Wherever we had code which did: if (something_bad) { perror (...); exit (EXIT_FAILURE); } replace this with use of the error(3) function: if (something_bad) error (EXIT_FAILURE, errno, ...); The error(3) function is supplied by glibc, or by gnulib on platforms which don't have it, and is much more flexible than perror(3). Since we already use error(3), there seems to be

Filters can be placed in front of plugins to modify their behaviour. This commit adds the <nbdkit-filter.h> header file, the manual page, the ‘filterdir’ directory (like ‘plugindir’), the ‘filters/’ source directory which will contain the actual filters, the ‘--filters’ parameter, and the filters backend logic. --- Makefile.am | 2 +- TODO | 17 +-
