[plasmashell] [Bug 450050] Desktop functionality degrades after a notification can't be shown (DBus connection instability?)
https://bugs.kde.org/show_bug.cgi?id=450050 Nate Graham changed: What|Removed |Added Resolution|--- |UPSTREAM CC||n...@kde.org Status|REOPENED|RESOLVED --- Comment #12 from Nate Graham --- I don't see how this could be a KDE issue. It could be a Firefox issue or a DBus server issue, but it seems extremely unlikely that any KDE code is to blame here. let's follow up on the upstream reports and if they bounce back here, we can re-open the bug. -- You are receiving this mail because: You are watching all bug changes.

I am willing and glad to provide any and all relevant information I can - even interactively in a live chat or screen sharing session, or similar - to any developer interested in getting to the end of this. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=450050 --- Comment #6 from torokat...@gmail.com --- One more thing: After Firefox crashes, then I restart it, I see this message printed in the console in which plasmashell is running: `kf.kio.gui: Failed to register new cgroup: "app-firefox\\x2dwayland-e15c52a3550c4762a2160b5e11b424cc.scope" "org.freedesktop.DBus.Error.Disconnected" "Not connected to D-Bus server"` And about the degraded state: Pressing the volume control keys, or the Super/Meta key does send a `globalShortcutPressed` or `activateLauncherMenu` (respectively) message on the Session bus. I can see them in Bustle, but plasmashell doesn't react by adjusting the volume and showing the OSD, or by popping up the application menu. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=450050 --- Comment #3 from torokat...@gmail.com --- I think I'm a bit closer to a semi-reliable reproduction method. The problem is, it only works on my main system, the one affected by this issue - but not on my laptop, which is very similar software-wise. Anyway, the steps I devised for triggering the glitch: 1.: Open https://www.bennish.net/web-notifications.html in Firefox (on Wayland, which may or may not matter), and make sure the page is a completely fresh tab, by pressing Ctrl+F5 2.: Click the "Authorize" button, and grant notification permissions to the site 3.: Verify that the notifications work by pressing the "Show" button a few times, then wait for all notifications to disappear 4.: Open the Web Developer Console on the page, and enter this: `setInterval(notify.show, 1000)`. This might rely on the fact that the default timeout is a whole number of seconds, so there can be race conditions between queueing a new notification, and receiving callback about it being shown, and an older one closing. 5.: Don't hover over any of the notifications and don't close them, so this potential race condition is kept going 6.: Open LibreOffice Writer, and copy a few lines of text from the page in Firefox into a new document in Writer (yes, for some reason, this also seems to be needed) 7.: Wait for a few more notifications to come and go, and not much later, Firefox should lock up, maybe crash, and plasmashell is now in the mentioned degraded state. If Bustle is recording the Session Bus in the meantime, it errors out and stops recording (see attached screenshot). Then, if I start a new Bustle recording, I see some corrupted-looking messages going around on the Session bus (see another attached screenshot). Also, in this degraded state, if I enter `notify-send test` to a terminal, it does nothing, but doesn't return either - it's just blocked indefinitely. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=450050 --- Comment #2 from torokat...@gmail.com --- (In reply to David Edmundson from comment #1) > If firefox gets locked up that is a firefox bug and needs to be reported > there. That's not on us. Firefox looks more like it is completely blocked waiting for something external. No obvious resource bottleneck, such as CPU usage or memory consumption, disk operations, etc. And it's always when trying to show a notification - now that I think about it, it doesn't even have to be about an incoming mail, it could be about a new YouTube upload, or something else. If I leave it alone, after several seconds, sometimes it resumes operation, then immediately shows the notification that triggered the glitch, but not in plasmashell, in its own little window instead. And after this, all further notifications are also shown using the internal fallback (as described), instead of by plasmashell. I was in fact not sure at all where to start reporting this: to dbus-broker, Firefox, the Fedora project, or here. It seemed like a fairly complex issue with all these pieces not properly cooperating. Sorry if it ends up not being the appropriate place, I just experienced most symptoms to be affecting Plasma. > You can capture a log with dbus-monitor or bustle (for a UI) when the > situation occurs. Thanks for the tip, Bustle looks really good! I'm going to try catching this occurrence with it, and will report back if I managed to do so. > >or causes the whole desktop to enter a strangely degraded state. > > can you expand on what this entails.

Overall the system is sort of usable, but a lot of small (inter-application) functionality stops working as it is supposed to, or as it did until that. > Please also confirm you're using plasmashell for notifcations not some third > party notification tool. I am not using anything out of the ordinary for notifications, just a plain Fedora KDE installation - granted, I have been updating it through a fair few major releases, I think I originally installed it as Fedora 28. I also have KDE Connect running, but it is not currently set up to mirror notifications from my phone to my desktop (nor the other way around), so I don't think that would interfere. -- You are receiving this mail because: You are watching all bug changes.
