Back in 08318a2c5a, value "false" was enabled for
'-Dtests=', but various tests were not conditionalized properly. So even with
-Dtests=false -Dslow-tests=false we'd run 120 tests. Let's make this consistent.
We would have a strange situation where after setting -Dslow-tests=true -Dtests=false
we'd get mostly the slow tests (plus some other ones which I'll fix in
subsequent commit). Let's simplify things by making -Dtests=false just
disable those tests too.
This makes it so that tests no longer need to know the absolute paths to the
source and build dirs, instead using the systemd-runtest.env file to get these
paths when running from the build tree.
Confirmed that test-catalog works on `ninja test`, when called standalone and
also when the environment file is not present, in which case it will use the
installed location under /usr/lib/systemd/catalog.
The location can now also be overridden for this test by setting the
$SYSTEMD_CATALOG_DIR environment variable.
This simplifies get_testdata_dir() to simply checking for an environment
variable, with an additional function to locate a systemd-runtest.env file in
the same directory as the test binary and reading environment variable
assignments from that file if it exists.
This makes it possible to:
- Run `ninja test` from the build dir and have it use ${srcdir}/test for
test unit definitions.
- Run a test directly, such as `build/test-execute` and have it locate
them correctly.
- Run installed tests (from systemd-tests package) and locate the test
units in the installed location (/usr/lib/systemd/tests/testdata), in
which case the absence of the systemd-runtest.env file will have
get_testdata_dir() use the installed location hardcoded into the
binaries.
Explicit setting of $SYSTEMD_TEST_DATA still overrides the contents of
systemd-runtest.env.
This also unifies __filter_units_by_property() and
__filter_units_by_properties(), and makes completion for 'restart',
'reload' or 'stop' show more candidates.
Actually check the return code from logind_schedule_shutdown() and proceed to
immediate shutdown if that fails. Negative return codes can be returned if
systemctl is compiled without logind support, or if logind otherwise failed
(either too old, disabled/masked, or it is incomplete
systemd-shim/systemd-service implementation).
