universal testing script
Of course the testing script I have pasted into the text of the bug has a bug itself. This is a corrected version.
This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. |
Created attachment 763487 [details] testing script Description of problem: When trying to discover which notification is urgent and which is not, I try to investigate which icon is shown in the gnome-shell. With the attached script I generate a notification via libnotify and then I try to investigate it with pyatspi (usually I would use dogtail, but in order to eliminate its possible guilt in the action, I am using only plain pyatspi). The result of running this script on my system is matej@wycliff: libnotify (rhel-7 *%)$ ./sample_reproducer.py DEBUG:<module>:found 173 icon elements. DEBUG:<module>:images = None ('summary', <Accessible object at 0x7f67c9807910 (AtspiAccessible at 0x10fe5d0)>) matej@wycliff: libnotify (rhel-7 *%)$ I don't think that line DEBUG:<module>:images = None is right. In order to eliminate possible bug with pyatspi I have also created this simple testing script: #!/usr/bin/python # -*- coding: utf-8 -*- import pyatspi, sys from pyatspi.utils import findAllDescendants, findDescendant def isAppNamed(node): return (node.getRoleName() == 'application') and \ (node.name == appname) appname = sys.argv[1] root = pyatspi.Registry.getDesktop(0) app = findDescendant(root, isAppNamed, breadth_first=True) print("app = %s" % app) icons = findAllDescendants(app, lambda x: x.getRoleName() == 'image') print("found %d icon elements." % len(icons)) for ico in icons: print("images = %s" % icons[0].get_image()) When I run it against for example Firefox (e.g., running ./app_reproducer.py Firefox) I get number of informations about images. Therefore the only culprit seems to me to be gnome-shell which somehow doesn't provide to pyatspi proper information. That unfortunately breaks my QA efforts. Version-Release number of selected component (if applicable): pyatspi-2.8.0-2.el7.noarch gnome-shell-3.8.3-2.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.run the above shown script for Firefox to see pyatspi API is working 2.run ./sample_reproducer.py 3. Actual results: see above Expected results: the .get_icon*() methods should return proper data for the icons. Additional info:
