From 4acc8a3168e5f11b5308cf8558d68bf2a0503444 Mon Sep 17 00:00:00 2001 From: huangkaibin <huangkaibin@huawei.com> Date: Mon, 7 Aug 2017 17:06:30 +0800 Subject: [PATCH] systemd: Activation service must be restarted when it is already started and re-actived by dbus When dbus-daemon service is killed, every activation service must be restarted to reestblished dbus connection between dbus-daemon and the service. Otherwise, there will be problem on the dbus connection. This patch fix this problem by set JobType to JOB_RESTART when it is re-actived in signal_activation_request function. --- src/core/dbus.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/src/core/dbus.c b/src/core/dbus.c index 29524d4..38940ef 100644 --- a/src/core/dbus.c +++ b/src/core/dbus.c @@ -152,6 +152,8 @@ static int signal_activation_request(sd_bus_message *message, void *userdata, sd const char *name; Unit *u; int r; + int jobtype; + Service *s = NULL; assert(message); @@ -177,7 +179,13 @@ static int signal_activation_request(sd_bus_message *message, void *userdata, sd goto failed; } - r = manager_add_job(m, JOB_START, u, JOB_REPLACE, NULL, &error, NULL); + jobtype = JOB_START; + s = SERVICE(u); + if(s && s->state != SERVICE_DEAD) { + jobtype = JOB_RESTART; + log_unit_info(u, "Service '%s' will be restarted to activate the service.
