>From 1a02a3add05b9a2a46d87c660f58cdfc0fa5640e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?P=C3=A1draig=20Brady?= Date: Wed, 6 Mar 2019 20:09:16 -0800 Subject: [PATCH] tests: test-N: fix false positives on some systems Testing by Assaf Gordon on OSX showed the atime wasn't being updated when explicitly set back in time. Also Debian 8.11 / mips64 was seen to not update the mtime when truncating an empty file. * tests/misc/test-N.sh: Isolate from different timestamping behaviors of various (file) systems, by correlating the timestamps with stat(1) before using `test -N`. --- tests/misc/test-N.sh | 22 ++++++++++++++++------ 1 file changed, 16 insertions(+), 6 deletions(-) diff --git a/tests/misc/test-N.sh b/tests/misc/test-N.sh index 348139b..0b1ccfe 100755 --- a/tests/misc/test-N.sh +++ b/tests/misc/test-N.sh @@ -17,26 +17,36 @@ # along with this program.
