Subject: [PATCH] test-login: skip consistency checks when logind is not active
|
|
MIME-Version: 1.0

There are two ways in swich sd_login_* functions acquire data:
|
|
some are derived from the cgroup path, but others use the data serialized
|
|
by logind.
|
|
|
|
When the tests are executed under Fedora's mock, without systemd-spawn
|
|
but instead in a traditional chroot, test-login gets confused:
|
|
the "outside" cgroup path is visible, so sd_pid_get_unit() and
|
|
sd_pid_get_session() work, but sd_session_is_active() and other functions
|
|
that need logind data fail.
|
|
|
|
Such a buildroot setup is fairly bad, but it can be encountered in the wild, so
|
|
let's just skip the tests in that case.
|
|
|
|
/* Information printed is from the live system */
|
|
sd_pid_get_unit(0, …) → "session-237.scope"
|
|
sd_pid_get_user_unit(0, …) → "n/a"
|
|
sd_pid_get_slice(0, …) → "user-1000.slice"
|
|
sd_pid_get_session(0, …) → "237"
|
|
sd_pid_get_owner_uid(0, …) → 1000
|
|
sd_pid_get_cgroup(0, …) → "/user.slice/user-1000.slice/session-237.scope"
|
|
sd_uid_get_display(1000, …) → "(null)"
|
|
sd_uid_get_sessions(1000, …) → [0] ""
|
|
sd_uid_get_seats(1000, …) → [0] ""
|
|
Assertion 'r >= 0' failed at src/libsystemd/sd-login/test-login.c:104, function test_login(). Aborting.
