From: Michael J Gruber Date: Tue, 16 Oct 2012 11:39:46 GMT Subject: [RFC/PATCH 3/4] test-lib: provide lazy TIME_COMMAND prereq Message-ID: <0140f3f2f2f4bded6868f4082bef0c36e9a8560e.1350387132.git.git@drmicha.warpmail.net> In-Reply-To: Some test want to use the time command (not the shell builtin) and test for its availability at /usr/bin/time. Provide a lazy prereq TIME_COMMAND which tests for /usr/bin/time and /bin/time. If any is found, set TEST_COMMAND_PATH to the first match. Signed-off-by: Michael J Gruber --- Rather than iterating over 2 or more hardcoded paths, one could use "test -P time" or allow a make variable TIME_COMMAND_PATH whose executability is checked by the prereq. I really don't know what's best. t/test-lib.sh | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/t/test-lib.sh b/t/test-lib.sh index 489bc80..7977c15 100644 --- a/t/test-lib.sh +++ b/t/test-lib.sh @@ -738,6 +738,13 @@ test_lazy_prereq UTF8_NFD_TO_NFC ' esac ' +test_lazy_prereq TIME_COMMAND ' + for command in /usr/bin/time /bin/time + do + test -x "$command" && break + done && TIME_COMMAND_PATH="$command" +' + # When the tests are run as root, permission tests will report that # things are writable when they shouldn't be. test -w / || test_set_prereq SANITY -- 1.8.0.rc2.304.g9f3ac5c
