Description Rex Dieter 2021-05-19 14:11:20 UTC
After upgrading to plasma-5.21.90, all krunner shortcuts stopped working.

Some users report seeing duplicates in systemsettings, and removing the dups fixes the issue... I'll try that and report back.
Comment 1 Rex Dieter 2021-05-19 14:17:35 UTC
Confirmed, I saw 2 entries in systemsettings->shortcuts for krunner, one with an icon one without

I deleted the one without, and reset defaults for the other, and things work again.

Fwiw, here's the diff of my ~/.config/kglobalshortcutsrc before and after the change:

Comment 2 Rex Dieter 2021-05-19 14:23:15 UTC
I suspect part of this was due to krunner.desktop being renamed to org.kde.krunner.desktop... in this commit ?

Comment 3 David Redondo 2021-05-19 15:17:17 UTC
There is an update script that should fix this
https://invent.kde.org/plasma/plasma-workspace/-/blob/master/krunner/update/krunnerglobalshortcuts.cpp


Do you have an entry like 

[krunnerglobalshortcuts.upd]
ctime=1621407975
done=5.17KRunnerGlobalShortcuts,5.22KRunnerGlobalShortcuts
mtime=1621393778

in .config/kconf_udpaterc and is /usr/share/kconf_update/krunnerglobalshortcuts.upd on your system?
Comment 4 Rex Dieter 2021-05-19 15:36:19 UTC
~/.config/kconf_udpaterc contains:
[krunnerglobalshortcuts.upd]
ctime=1621260782
mtime=1620912182


$ cat /usr/share/kconf_update/krunnerglobalshortcuts.upd

Comment 5 David Redondo 2021-05-20 06:37:43 UTC

I think at least, not sure why we have the times but not the "done" entry tbh.

What happens if you run 

kconf_update --debug /usr/share/kconf_update/krunnerglobalshortcuts.upd

kconf_update should be in the libexec dir on your system in a kf5 subfolder
Comment 7 Nate Graham 2021-05-20 18:35:38 UTC
FWIW I can reproduce this in the Wayland session but not the X11 session.

$  cat /usr/share/kconf_update/krunnerglobalshortcuts.upd

This file is out of date but you probably have a newer one in your prefix?

Comment 10 Nate Graham 2021-05-21 15:24:22 UTC
Hmm, now they are working for me again. I guess it's not this.
Comment 11 Fabian Vogt 2021-06-08 20:55:38 UTC
openQA sees a similar issue (X11. Wayland upgrades not tested): https://openqa.opensuse.org/tests/1774482#step/updates_packagekit_kde/1

The journal shows "No desktop file found for service krunner.desktop", so this is most likely related to this migration. Restarting kglobalaccel5 helped. Does the upgrade script maybe not apply to an already running kglobalaccel5?
Comment 12 Nate Graham 2021-06-08 21:00:44 UTC
Urgh
Comment 13 David Redondo 2021-06-09 07:27:58 UTC
>oes the upgrade script maybe not apply to an already running kglobalaccel5

It needs kglobalaccel5 running, we are instructing it do the changes insted of changing the config file under its feet.

What I find interesting that I saw no 
"Disabling desktop file" https://invent.kde.org/frameworks/kglobalaccel/-/blob/master/src/runtime/kserviceactioncomponent.cpp#L133
in the log which we should hit when we call 
  KGlobalAccel::self()->cleanComponent
(or do we not see debugs in openqa configuration?)

Which I thought maybe KGlobalAccel::isComponentActive(oldDesktopFile) is maybe false if the file is not longer present but I could confirm that to be not the case.
Comment 14 David Redondo 2021-06-09 07:40:37 UTC
A manual test:
 - move /usr/share/kglobalaccel/org.kde.krunner.desktop to /usr/share/kglobalaccel/krunner.desktop
 - qdbus org.kde.kglobalaccel /component/org_kde_krunner_desktop org.kde.kglobalaccel.Component.cleanUp (should return true)
 - restart kglobalaccel5

We are now in the initial situation when you are running plasma 5.21

- undo the move from the first step, to simulate the update to 5.22
- run [...]/kconf_update_bin/krunnerglobalshortcuts (kded should  have run this in case of the upgrade)

For me this transfers the shortcuts to the new correct org.kde.krunner.desktop component

krunnerglobalshortcuts: Prevent actions from becoming inactive

If a QAction is destroyed, KGlobalAccel will automaticaly set it
to inactive. To prevent this put them on the heap and intentionally
leak them as it did before.

Should be fully fixed with that. Please re-open if your KRunner shortcuts are still broken after upgrading to Plasma 5.22.1 and rebooting. Don't forget the reboot. :)

Comment 22 Ricardo J. Barberis 2021-06-23 01:09:28 UTC
FWIW, I had this issue after upgrading to Plasma 5.22.0 and Gear 21.04.2.

A couple of day later I upgraded to Frameworks 5.83 and the problem was solved, so I didn't need to upgrade to Plasma 5.22.1

My O.S. is Slackware64 current (a.k.a. 15.0 beta).

At least openQA and my manual testing hasn't seen any issues with upgrades from 5.12, 5.18 and 5.21.5 anymore, so I don't think it's broken in general. Maybe there's some edge case with certain configs. Can you get kglobalshortcutsrc from the reporter?
Comment 24 Rex Dieter 2021-08-27 14:49:21 UTC
Users are still reporting as unfixed, reopened.

I'll direct them here to provide additional feedback, thanks.
Comment 25 Nate Graham 2021-10-13 19:32:20 UTC
No users have shown up to provide feedback. :(

Given that it doesn't seem to be widely reproducible, without additional information, we won't be able to investigate further.
Comment 26 Dmitry Vinokurov 2021-10-15 13:24:12 UTC
Sorry if it is the wrong place, but I've just upgraded to Kubuntu 21.10 from 21.04 and faced this bug. Plasma 4:5.22.5-0ubuntu1. Found 2 Krunner entries in keyboard shortcuts, one disabled and other with expected keys, reassigned - everything works now, but I still think that something is wrong with installation scripts and it should not be so, because this bug is not very easy to Google.
Comment 27 Rex Dieter 2021-10-15 13:28:03 UTC
Still unresolved, just had a user report seeing this today in chat

Comment 29 Rex Dieter 2021-10-15 13:39:34 UTC
I'll try to come up with reproducibility steps, iirc, it's not that hard to trigger this.
Comment 30 Gene 2021-10-15 14:54:48 UTC
I am having this issue on Fedora 34. Shortcuts shows that both alt+space and alt+f2 should open krunner but they do not.
Comment 31 David Redondo 2021-10-19 07:21:33 UTC
I have no idea since manual set up and OpenQa both worked. 
5.22 is also EOL, so people who would be affected by this would be 
upgrading form 5.21 to 5.23 or later, not sure how common

It looks like Fedora 34 is using 5.22.5 as of today. I can't speak to what is eol and what's not, but it seems that if even Fedora's current distro is impacted by this it is still relevant since very few users will be running something newer than that.
Comment 33 Tom Chiverton 2021-10-26 08:18:25 UTC
Broken in Kubuntu backports too

Two krunner entries in system settings, both missing icons. Removed, but can't re add.

It's very broken.

Comment 34 Tom Chiverton 2021-10-26 08:21:47 UTC
Work around is to add a manual custom shortcut, with the alt+space etc mappings, that just runs /usr/bin/krunner

Not sure how something so simple and unchanged since forever gets busted.
Comment 35 Nuno Costa 2021-12-04 14:23:11 UTC
I upgraded to Fedora 34 recently and following the same steps mentioned in Comment 1, made KRunner shortcuts work again.
I remember being affected by Bug 413368 in Fedora 31.

Comment 37 Fabian Vogt 2022-08-17 13:59:16 UTC
For some reason this now started to fail in openQA tests which upgrade from 5.8/5.12/5.18 (Leap 42.x/15.x) -> 5.24 (Tumbleweed). First, kglobalacceld crashes and after the automatic restart the situation is as outlined in this report: Two entries in kglobalshortcutsrc which don't work. At least in openQA this looks like it's reproducible. Unfortunately I wasn't able to get a backtrace, but it seems to be heap corruption ("unaligned fastbin chunk detected"). The crash is not reproducible manually at least.

This matches the arrival of Frameworks 5.97 in Tumbleweed. I can't tell how much 5.97.0 actually caused this or just exposed it more...

CC Ahmad, who did the majority of changes in kglobalaccel 5.97.

It's actually fairly simple: kglobalacceld crashes when the kconf_update binary runs. With valgrind, the cause is obvious:

void GlobalShortcutsRegistry::writeSettings() const
{
    const auto &lst = GlobalShortcutsRegistry::self()->allMainComponents();
    for (const KdeDGlobalAccel::Component *component : lst) {
        KConfigGroup configGroup(&_config, component->uniqueName());
        if (component->allShortcuts().isEmpty()) {
            configGroup.deleteGroup();
            delete component;
        } else {
            component->writeSettings(configGroup);
        }
    }

    _config.sync();
}

That method destroys the component, but leaves it in the m_components vector of the shortcuts registry, i.e. it generates dangling pointers. This results in all kinds of fun, in particular double-, triple- and quadruple- frees each time writeSettings is called. I think it just worked by sheer luck when QHash was still used. Reverting that commit makes the immediate valgrind complaints stop, but it still crashes at some point later due to latent memory corruption. I think this explains the not fully reproducible issues prior to 5.97 well.

"obvious" - ha! I wrote too soon.

~Component actually calls registry->takeComponent so it modifies m_components.
The subtle addition of "&" in the QHash -> std::vector commit means that the container
being iterated gets changed underneath the method. Just removing the "&" again doesn't
fix the crash though, it just crashes differently, taking valgrind with it... Needs a closer look.

I tried it again from a clean slate and just removing the "&" fixed the issue completely, yay.
Unfortunately that also means that it's unrelated to the remaining "shortcuts lost" issues
and effectively I hijacked this bug report for something new...

Avoid iterating a container while it's being mutated

> Was that enough to fix it, or do we need something else?

The fix following comment 37 was for a regression in KF 5.97, so actually unrelated to the original report. I have no idea what the state of the original bug is after it was apparently not fully fixed (comment 21), I was never able to reproduce it and openQA doesn't see it either.
Comment 47 Nate Graham 2022-09-08 14:54:27 UTC
Ok, then let's close this since it seems like it's not clear that the original issue is indeed still a problem.
Comment 48 Shriramana Sharma 2022-11-28 11:21:13 UTC
My KDE keyboard switching shortcuts started malfunctioning over the past one month… Before that it was fine. I'm using Kubuntu Jammy  22.04.1 with latest updates. Any idea when I can get this fixed on my system?
Comment 49 Andy Simpkins 2023-07-21 07:16:58 UTC
I note that there were reports that users were not reporting this issue.
Reading through this bug I was able to fix my upgrade from Debian 11 to Debian 12. where the krunner shortcuts stopped working.

It might be worth including a test / auto recover script and pushing it to the distros explicitly so that users with even less clue than me get an update to fix the problem.

Thanks for all your great work
