Description Ondrej 2020-05-12 08:36:48 UTC

Actual results:
Currently, notify-send always returns zero, regardless of the actual success in the notification.


Expected results:
Ideally, it should return non-zero if the notification was not sent (i.e. no dbus connection or such)

Can you provide some reproducer for this issue? Do you have something in logs or something of an indication that it was sent but the notification did not go through? I am not sure how to start reproducing this. What came to mind was to stop message bus, send the notification and check the return message, but the bus could be back up before the notification actually goes through.

systemctl stop messagebus;notify-send -u CRITICAL ABC; echo $?

It would be of great value to have some better reproducer. Thanks

Comment 4 Ondrej 2020-05-12 10:16:54 UTC

Well, it seems the issue is easy to reproduce - ssh to a RH-8 box, then execute 'notify-send  "hello world"'.
Ideally, this should return a failure as no GUI (Gnome session) running so nowhere to display the message.
Is it possible to achieve?

Also, easier test:
$ export DBUS_SESSION_BUS_ADDRESS=nonsense
$ notify-send "hello world"
- returns 0, should return non-zero as invalid DBUS configured
