[Bug]:A goroutine memory leak

[xuxiaofan1203]

Hello @marselester, the dbus is very useful, but I found a potential bug when I used it.
blocking position:

dbus/conn.go

Line 302 in 7623695

<-conn.ctx.Done()

In the test function TestSessionBus, after using the newConn, there is no newConn.Close() to awaken the <-conn.ctx.Done(). So the goroutine will block at the <-conn.ctx.Done(). We can call newConn.Close() to fix the bug probably.

dbus/conn_test.go

Lines 26 to 32 in 7623695

	newConn, err := SessionBus()
	if err != nil {
	t.Error(err)
	}
	if newConn == oldConn {
	t.Fatal("Should get a new connection")
	}

you could reproduce the bug using goleak in the func TestSessionBus like this

Yes, I found the bug too. The newConn should be closed to awaken the ctx.Done().
