From 53cc4303b98e85bc0144d9ddaff1c116c7e757a3 Mon Sep 17 00:00:00 2001 From: ngie Date: Fri, 10 Feb 2017 02:21:57 +0000 Subject: MFC r304797,r305467: r304797 (by jmmv): Make use of Kyua's work directories. Change the vnode tests to use the current directory when creating temporary files, which we can assume is a volatile work directory, and then make the kqueue_test.sh driver _not_ abandon the directory created by Kyua. This makes the various kqueue tests independent of each other, and ensures the temporary file is cleaned up on failure. Problem spotted by asomers@ when reviewing D4254. r305467: Move tests/sys/kqueue/... to tests/sys/kqueue/libkqueue/... This is being done to clearly distinguish the libkqueue tests from the (soon to be imported) NetBSD tests. --- tests/sys/kqueue/libkqueue/vnode.c | 266 +++++++++++++++++++++++++++++++++++++ 1 file changed, 266 insertions(+) create mode 100644 tests/sys/kqueue/libkqueue/vnode.c (limited to 'tests/sys/kqueue/libkqueue/vnode.c') diff --git a/tests/sys/kqueue/libkqueue/vnode.c b/tests/sys/kqueue/libkqueue/vnode.c new file mode 100644 index 0000000..55d5b3f --- /dev/null +++ b/tests/sys/kqueue/libkqueue/vnode.c @@ -0,0 +1,266 @@ +/* + * Copyright (c) 2009 Mark Heily + * + * Permission to use, copy, modify, and distribute this software for any + * purpose with or without fee is hereby granted, provided that the above + * copyright notice and this permission notice appear in all copies. + * + * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES + * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF + * MERCHANTABILITY AND FITNESS.
