From 646853bdd8b1337204643aa014ff3f1f49d91a4f Mon Sep 17 00:00:00 2001 From: Topi Miettinen Date: Tue, 13 Sep 2016 06:20:38 +0000 Subject: fileio: simplify mkostemp_safe() (#4090) According to its manual page, flags given to mkostemp(3) shouldn't include O_RDWR, O_CREAT or O_EXCL flags as these are always included. Beyond those, the only flag that all callers (except a few tests where it probably doesn't matter) use is O_CLOEXEC, so set that unconditionally. --- src/test/test-acl-util.c | 2 +- src/test/test-async.c | 2 +- src/test/test-clock.c | 2 +- src/test/test-copy.c | 12 ++++++------ src/test/test-fd-util.c | 8 ++++---- src/test/test-fdset.c | 16 ++++++++-------- src/test/test-fileio.c | 24 ++++++++++++------------ src/test/test-fs-util.c | 2 +- src/test/test-glob-util.c | 2 +- src/test/test-hostname-util.c | 2 +- src/test/test-stat-util.c | 4 ++-- src/test/test-terminal-util.c | 2 +- src/test/test-tmpfiles.c | 2 +- src/test/test-unit-file.c | 10 +++++----- 14 files changed, 45 insertions(+), 45 deletions(-) (limited to 'src/test') diff --git a/src/test/test-acl-util.c b/src/test/test-acl-util.c index 430dda8e78..5b572bb0bf 100644 --- a/src/test/test-acl-util.c +++ b/src/test/test-acl-util.c @@ -35,7 +35,7 @@ static void test_add_acls_for_user(void) { uid_t uid;
