From 814cc562121270e2d5de0630b773792c74990a9c Mon Sep 17 00:00:00 2001 From: Michal Schmidt Date: Sat, 2 Mar 2013 22:31:09 +0100 Subject: core: single unit_kill implementation for all unit types There are very few differences in the implementations of the kill method in the unit types that have one. Let's unify them. This does not yet unify unit_kill() with unit_kill_context(). --- src/core/service.c | 60 +----------------------------------------------------- 1 file changed, 1 insertion(+), 59 deletions(-) (limited to 'src/core/service.c') diff --git a/src/core/service.c b/src/core/service.c index 3fbb0a136d..fd90ceba05 100644 --- a/src/core/service.c +++ b/src/core/service.c @@ -3711,65 +3711,7 @@ static void service_reset_failed(Unit *u) { static int service_kill(Unit *u, KillWho who, int signo, DBusError *error) { Service *s = SERVICE(u); - int r = 0; - Set *pid_set = NULL; - - assert(s); - - if (s->main_pid <= 0 && who == KILL_MAIN) { - dbus_set_error(error, BUS_ERROR_NO_SUCH_PROCESS, "No main process to kill"); - return -ESRCH; - } - - if (s->control_pid <= 0 && who == KILL_CONTROL) { - dbus_set_error(error, BUS_ERROR_NO_SUCH_PROCESS, "No control process to kill"); - return -ESRCH; - } - - if (who == KILL_CONTROL || who == KILL_ALL) - if (s->control_pid > 0) - if (kill(s->control_pid, signo) < 0) - r = -errno; - - if (who == KILL_MAIN || who == KILL_ALL) - if (s->main_pid > 0) - if (kill(s->main_pid, signo) < 0) - r = -errno; - - if (who == KILL_ALL) { - int q; - - pid_set = set_new(trivial_hash_func, trivial_compare_func); - if (!pid_set) - return -ENOMEM; - - /* Exclude the control/main pid from being killed via the cgroup */ - if (s->control_pid > 0) { - q = set_put(pid_set, LONG_TO_PTR(s->control_pid)); - if (q < 0) { - r = q; - goto finish; - } - } - - if (s->main_pid > 0) { - q = set_put(pid_set, LONG_TO_PTR(s->main_pid)); - if (q < 0) { - r = q; - goto finish; - } - } - - q = cgroup_bonding_kill_list(UNIT(s)->cgroup_bondings, signo, false, false, pid_set, NULL); - if (q < 0 && q != -EAGAIN && q != -ESRCH && q != -ENOENT) - r = q; - } - -finish: - if (pid_set) - set_free(pid_set); - - return r; + return unit_kill_common(u, who, signo, s->main_pid, s->control_pid, error); } static const char* const service_state_table[_SERVICE_STATE_MAX] = { -- cgit v1.2.3-54-g00ecf
