Add trivial test connecting via systemd socket activation. Signed-off-by: Nir Soffer <nsoffer(a)redhat.com&gt; --- Changes in v2: - Skip test if nbdkit or nbdkit memory plugin are not available (Richard) - Use single connection, supporting multiple connections needs more work. v1 was here: https://listman.redhat.com/archives/libguestfs/2021-November/msg00049.html tests/Makefile.am | 9 ++++ tests/connect-systemd-socket-activation.c | 65 +++++++++++++++++++++++ 2 files changed, 74 insertions(+) create mode 100644 tests/connect-systemd-socket-activation.c diff --git a/tests/Makefile.am b/tests/Makefile.am index 7f00f6f..0074acf 100644 --- a/tests/Makefile.am +++ b/tests/Makefile.am @@ -192,6 +192,7 @@ check_PROGRAMS += \ opt-list \ opt-info \ opt-list-meta \ + connect-systemd-socket-activation \ connect-unix \ connect-tcp \ connect-tcp6 \ @@ -235,6 +236,7 @@ TESTS += \ opt-list \ opt-info \ opt-list-meta \ + connect-systemd-socket-activation \ connect-unix \ connect-tcp \ connect-tcp6 \ @@ -424,6 +426,13 @@ opt_info_LDADD = $(top_builddir)/lib/libnbd.la opt_list_meta_SOURCES = opt-list-meta.c opt_list_meta_LDADD = $(top_builddir)/lib/libnbd.la +connect_systemd_socket_activation_SOURCES = \ + connect-systemd-socket-activation.c \ + requires.c \ + requires.h \ + $(NULL) +connect_systemd_socket_activation_LDADD = $(top_builddir)/lib/libnbd.la + connect_unix_SOURCES = connect-unix.c connect_unix_LDADD = $(top_builddir)/lib/libnbd.la diff --git a/tests/connect-systemd-socket-activation.c b/tests/connect-systemd-socket-activation.c new file mode 100644 index 0000000..64da2b6 --- /dev/null +++ b/tests/connect-systemd-socket-activation.c @@ -0,0 +1,65 @@ +/* NBD client library in userspace + * Copyright (C) 2021 Red Hat Inc. + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
