glib/gio/tests/gdbus-peer.c
Simon McVittie 60c3c948b5 gio/tests/gdbus-peer: Exercise fds attached to a large message 
This incidentally also exercises the intended pattern for sending fds in
a D-Bus message: the fd list is meant to contain exactly those fds that
are referenced by a handle (type 'h') in the body of the message, with
numeric handle value n corresponding to g_unix_fd_list_peek_fds(...)[n].

Being able to send and receive file descriptors that are not referenced by
a handle (as in OpenFile here) is a quirk of the GDBus API, and while it's
entirely possible in the wire protocol, other D-Bus implementations like
libdbus and sd-bus typically don't provide APIs that make this possible.

Reproduces: https://gitlab.gnome.org/GNOME/glib/-/issues/2074
