重启单元文件时模式和通道应该是什么

Question

在go-systemd中，重启设备的第二个和第三个参数应该是什么。

// RestartUnit restarts a service.  If a service is restarted that isn't
// running it will be started.
func (c *Conn) RestartUnit(name string, mode string, ch chan<- string)    (int, error) {
return c.startJob(ch, "org.freedesktop.systemd1.Manager.RestartUnit", name, mode)
}

Answer 1

来自 PR 203, you can see that method used/tested 作为：

// Restart the unit
reschan = make(chan string)
_, err = conn.RestartUnit(target, "replace", reschan)
if err != nil {
    t.Fatal(err)
}

job = <-reschan
if job != "done" {
    t.Fatal("Job is not done:", job)
}

所以你必须创建自己的标签和频道。

来自dbus/methods.go

// Takes the unit to activate, plus a **mode string**.

The mode needs to be one of:

replace (the call will start the unit and its dependencies, possibly replacing already queued jobs that conflict with this),

fail (the call will start the unit and its dependencies, but will fail if this would change an already queued job),

isolate (the call will start the unit in question and terminate all units that aren't dependencies of it),

ignore-dependencies (it will start a unit but ignore all its dependencies),

ignore-requirements (it will start a unit but only ignore the requirement dependencies).

It is not recommended to make use of the latter two options.
