From cdaf5070480c09a7650589fa02b4d59c0af00112 Mon Sep 17 00:00:00 2001 From: Filipe Brandenburger Date: Sun, 8 Nov 2015 10:19:45 -0800 Subject: test-execute: Fix systemd escaping and shell issues In most cases, systemd requires escaping $ (for systemd variable substitution) and % (for specifiers) by doubling them. This was somewhat of an issue in tests like exec-environment*.service where systemd was doing the substitutions and we were not really checking that those were available in the actual environment of the command. Fix that. Expressions such as `exit $(test ...)` are incorrect. They only work because $(test ...) will produce no output, so the command will become a bare "exit" which will exit with the status of the latest executed command which turns out to be the test... The direct approach is simply calling "test" as the last command, for which the shell will propagate the exit status. One situation where this was breaking tests was on `exit $(test ...) && $(test ...) && $(test ...)` where the second and third tests were not really executing, since the first command is actually `exit` so && was doing nothing there. Fixed it by just using `test ... && test ... && test ...` as it was initially intended. Pass -x to all shell executions for them to produce useful debugging output to stderr. Consequently, removed most of the explicit `echo`s that are no longer needed. Mark all units as Type=oneshot explicitly. Also made sure all shell variables are properly quoted. v2: Added an explicit LC_ALL=C to ionice invocations since some locales (such as French) will add a space before the colon in the output. Tested by running `sudo ./test-execute` and confirming all tests enabled on my system (essentially all of them except for the s390 one) passed. Tweaked the variables or options or expected values and confirmed the tests do indeed fail when the values are not exactly the expected ones. v2: Also tested with `LANG=fr_FR.UTF-8 sudo ./test-execute` to confirm it still works in a different locale. --- test/test-execute/exec-umask-0177.service | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'test/test-execute/exec-umask-0177.service') diff --git a/test/test-execute/exec-umask-0177.service b/test/test-execute/exec-umask-0177.service index af9295888e..a5e8fc4dbc 100644 --- a/test/test-execute/exec-umask-0177.service +++ b/test/test-execute/exec-umask-0177.service @@ -2,6 +2,7 @@ Description=Test for UMask [Service] -ExecStart=/bin/sh -c 'touch /tmp/test-exec-umask; s=$(stat -c %a /tmp/test-exec-umask); echo $s; exit $(test $s = "600")' +ExecStart=/bin/sh -x -c 'touch /tmp/test-exec-umask; mode=$$(stat -c %%a /tmp/test-exec-umask); test "$$mode" = "600"' +Type=oneshot UMask=0177 PrivateTmp=yes -- cgit v1.2.3-54-g00ecf
