[Bug 1949615] Re: Notify method not working correctly in 21.10 (impish)

[Gordon Lack]

This python program shows the problem

*=*=* Cut here *=*=*
#!/usr/bin/python3
# -*- coding: utf-8 -*-
#
from pydbus import SessionBus
from time import sleep

##### Global constants
#
item            = "org.freedesktop.Notifications"
path            = "/org/freedesktop/Notifications"
interface       = "org.freedesktop.Notifications"
app_name        = "NotifyTest"
icon            = "/usr/share/icons/breeze/devices/64/camera-web.svg"
actions_list    = []
hint            = {}

bus = SessionBus()
notifications = bus.get('.Notifications')

##### Global variables
#
our_notify_id = 0
timeout = 3000      # ms
wait4 = 0           # s
body = "from NotifyTest.py"

while wait4 < 6:
    wait4 += 1
    message = "The next wait will be %ss" % wait4

# This should replace any previous notification still there...
# (can do this with notify-send command, but doing it in python allows
# us to use a fixed id for replacement).
#
    our_notify_id = notifications.Notify(app_name, our_notify_id, icon,
       message, body, actions_list, hint, timeout)
    print("our_notify_id:", our_notify_id)

# At Ubuntu 21.10 we have to change this to get the new message seen...
#
#    our_notify_id += 1
    print(message)

    sleep(wait4)

print("Done")

On 21.04 after the sleep exceeds the 3s timeout a new info message box
is displayed.

On 21.10 after the sleep exceeds the 3s timeout nothing is shown.

Title:
  Notify method not working correctly in 21.10 (impish)

Status in dbus package in Ubuntu:
  New

Bug description:
  The replaces_id parameter to org.freedesktop.Notifications.Notify no longer works correctly at 21.10.
  It is OK on 21.04.

  At 21.10 if a message with replaces_id === x ever times out then any
  further message sent with that replaces_id never gets shown.  The
  timeout-over seems to become permanent for that replaces_id.

  Example program to follow....
