Bug ID: 422042
Summary: KNotification uses transient=true hint incorrectly
Product: frameworks-knotifications
Version: 5.70.0
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kdelibs-b...@kde.org
Reporter: accounts.bugs.kde....@zauberfisch.at
CC: kdelibs-b...@kde.org
Target Milestone: ---
SUMMARY
KNotification turns transient=true if persistent=false. But according to the
specs, those 2 things are completely different and should not be connected in
this way.
The spec https://developer.gnome.org/notification-spec/ has 2 hints:
resident -> information how to display a notification (basically saying timeout
= infinity)
transient -> information how to handle a notification (eg to log it or to
discard it)
I haven't looked into it to much, but as far as I can tell from
https://invent.kde.org/frameworks/knotifications/-/blob/master/src/notifybypopup.cpp#L297
KNotification will do the following:
if (persistent == true)
timeout = 0 (infinite)
else
transient = true
I believe a notification framework should expose an api for applications to set
transient and resident directly and independent of each other.
I have observed this behavior in applications that use KNotification on non KDE
plasma desktops (xfce+xfce-notifyd, i3+dunst). If and how a plasma desktop is
effected I have not tested.
STEPS TO REPRODUCE
1. use xfce-notifyd or dunst as notification daemon
2. trigger a notification via NotifyByPopupPrivate::sendNotificationToServer
(for example the quassel irc client does that for private messages if the irc
client is not focused)
3. observe the dbus messages.
OBSERVED RESULT
The application does not set transient, but the dbus message contains a
transient=true hint.
Here the output of dbus-monitor when receving a notification in the quassel irc
client:

EXPECTED RESULT
The application should not set transient=true, unless the application has
specified to do so.
