Red Hat Bugzilla – Bug 1269190
Libreport should be able to keep its window above
Last modified: 2017-08-08 08:17:19 EDT
Description of problem:
Libreport is used by python-meh for graphical crash reporting in the Anaconda installation environment and by Initial Setup after the installation. This graphical environment is very simple and does not support switching between windows.
This has the side effect that if the user click outside of the libreport window while filling in bugrpoert details the window (and any user input inside it) will be lost, as it gets hidden behind the Anaconda window without any means of getting it back.
This can be prevented by libreport providing an option to show its window in a keep-above mode, so that it can't loose focus, which in turn prevents the data loss due to the hidden window.
Steps to Reproduce:
1. start installation in the graphical mode
2. trigger an exception
3. select the option to report a bug to bugzilla
4. once the libreport window shows up click outside of it
The window vanishes (it gets hidden behind the Anaconda window) and there is no way to get it back.
Clicking outside of the window does nothing, the libreport window keeps focus until terminated.
The Connection Editor utility, which is also used in a similar way in Anaconda and Initial Setup, has recently implemented this functionality to prevent similar issues with loosing user entered data.
This has been implemented by adding a --keep-above flag top the CLI API Anaconda uses the launch Connection Editor, which internally triggers the gtk_window_set_keep_above call.
As libreport is used via the Python API by python-meh in the Anaconda/IS environment the API should proabably be extended so that the keep-above mode can be requested for the libreport window.

Martin, can't you use wmctrl from anaconda environment to set correct window flags on arbitrary windows, without the need for each to implement this?

We have investigated this with vtrefny and it looks like wmctrl won't do:
* it seems to only work with Metacity
- we currently do use Metacity on our installation images, but live images can & do use different WMs
- Initial Setup runs after installation and often also runs under different WM than Metacity
* it only works with X
- this could be an issue when Wayland is the default
* upstream looks pretty dead (latest version is from 10th October 2005)
* the window is spawned from an imported module, not by calling a binary so there might be issues to differentiate the libreport window from the Anaconda ones
On the other hand the suggested solution (calling gtk_window_set_keep_above from libreport) is already known to work fine all the environments where Anaconda and Initial Setup is expected to be running.
It is also a part of the GTK public API, so we can expect it should work in the same way also on Wayland.
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.
More information and reason for this action is here:
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
