*** This bug has been marked as a duplicate of bug 435991 ***

I'm reopening this, Bug 435991 was caused by kded crash, we need to investige this one separately.

Hi Vaclav, can you give more details?

* on which version it was working? You wrote about upgrade to 5.21.4, which version was before?

* is this crash always reproducible?

* you wrote that it does not happen on fresh user - this is very interesting! Can you investigate more? My guess is that somethings starts alongside Plasma session, application that registers System Tray icon.

* can you share logs from Plasma and system logs? You can start Plasma by running:
> kquitapp5 plasmashell
> QT_LOGGING_RULES=*kde*=true kstart5 plasmashell
In system logs there should be entries like:
> kded5[2444]: Registering ":1.172/org/ayatana/NotificationItem/Skype1" to system tray
* from info attached to this bug report I see that you are using Linux From Scratch. This is pretty uncommon - are you using any additional hardening, compiler flags or anything non standard (besides installing from scratch :))

Hey Konrad,

thanks for looking into it.

My previous Plasma version (and the one I'm now back on for now) was from last December so most likely 5.20.4.

It is pretty much reproducible on my main user account. I had actually managed to get rid of the bug for a while by deleting most of the KDE configuration files from ~/.config and starting from scratch. But than I ran into it again once I started to play around with the sys tray. I think once I start up anything that involves dealing with the system tray (adding icons to it?), the crash occurs. I specifically remember having it happen after starting up Ktorrent and Skype.

I'll try to reproduce it once again on the clean test account. It didn't occur there at first but I'm now not sure I really tried hard enough. I'll get back to you on it in a bit.

I'm not using any special flags or hardening and stuff. Although I should probably mention that I had a bit of a trouble getting libksysguard to build - it kept failing on me like this:

make: *** [Makefile:130: all] Error 2

Which in the end I only managed to fix by adding "link_libraries(stdc++fs)" to the (almost) very top of CMakeLists.txt. It doesn't sound like something that has anything to do with the sys tray but I'm better mentioning it anyway.

I'm going to try get the plasmashell logs you mention on my other (test) machine (I fear I'd break this main rig of mine again - sadly, it wasn't as easy to downgrade back to 5.20.4).

OK, managed to reproduce it, on my test machine (which is pretty much the exact copy of my main rig). Plasma started up just fine, then I executed in Konsole those two commands you gave me, then I went on to start up KTorrent and voila - Plasma crashed. This is what I've got in Konsole:

listIcons.sh

I'm sorry - would you like me to run that listIcons.sh script?

Also, I've tried again using my test account (on this main rig of mine - I've just switched the "kf5" symlink to point to the 5.21.4 Plasma build) and while I did have Plasma crash on me once, I can't really reproduce it reliably there no matter what I do - I kept trying starting up and closing a few sys tray affecting apps over and over and no luck to make it crash, apart from that one time.

Can you run attached script before running KTorrent? It lists SNI icons. System tray has two types of items: applets and Status Notifier Items (SNI). Ktorrent, Skype, Discord and etc are using SNI to add icons to System Tray.

Can you attach fresh crash after running KTorrent (the best as en attachment, it is quite long)? If you have troubles generating backtrace, please check:
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Maybe that's the root cause - in Bug 435991 kded5 process was crashing in loop, causing crash in system tray. Maybe your situation is similar.

> and while I did have Plasma crash on me once, I can't really reproduce it
That one crash - was the cause the same? Do you have backtrace (coredump)?

If it is not crashing after change in symlink/compile paths/etc then this is good news!

As a separate task I will fix plasma crashing on kded5 restart.

Crash dump after running ktorrent (copied from KDE Crash Handler)

I should possibly mention one more thing perhaps somewhat unique to my setup and that is that I have two panels (top + bottom), both containing the sys tray, the bottom one however displaying just the keyboard layout icon and nothing else.

Possibly not important at all, just saying...

Sadly, I was a bit too quick to close the Crash Handler dialogue window that one time. :-( Sorry...

I'm not sure this could possibly have anything to do with that "/opt/kf5" symlink. That symlink just points to either /opt/kf5-5.77.0 or /opt/kf5-81.0.0 to switch between the two completely separate builds. I can't see the two affecting one another.

Crash dump on the test user account

Tried once more to make it crash on that fresh user account and after a while I did - this time after trying to start up Kopete. Was smart enough this time to save the dump so there you are. Looks like the same kind of crash to me...

Plasma 5.21 requires at least KF5 5.78. KDE Neon uses 5.81.

(In reply to Vaclav Masin from comment #14)
> Looks like the same kind of crash to me...
Yes, it is the same. Was it with old or new KF5?

Yeah, I'm aware. Those directory names are probably a bit misleading. They both contain complete sets of KDE tools from the respective time period, not just the Frameworks.

This was also on the 5.21.4 Plasma (and KF 5.81).

I've tried again with the patch applied and it's still crashing for me.

I've only rebuilt plasma-framework-5.81.0, mind you, not the whole Plasma. But I believe that should be sufficient, shouldn't it?

You read my mind :) Unfortunately your case is not caused by the same issue and is really strange. It should not be possible...

Can you apply attached patch? It is an ugly workaround, Plasma should not crash anymore. It also adds some logs, so can you run plasmashell from terminal (for example with kquitapp5 and kstart5) until you get log starting with: "No DataContainer for"? Then please run listIcons.sh. I don't know what is going on - KTorrent adds new icons (SNI) to System Tray, then "model" with all icons is sorted and Plasma crashes while trying to read data from one of the items. I wonder if that's the newly added item/icon, or something different.

I'm starting to feel a little bit bad for taking so much of your time on an issue that due the uniqueness of my setup is quite possibly experienced by no one else on the whole planet than me.

Anyway, the "ugly" patch indeed seems to prevent plasmashell from crashing. I'm going to attach the two outputs you ask for now.

Quite possibly, but it already motivated me to fix similar problem :) It is possible that your issue is totally valid and can happen for someone else. It is also possible that is unique to your setup. We can try to investigate a little bit more, fit it or leave it - at least there is a workaround.
Of course this works in other direction - if you are fed up with this just comment we can leave it as it is.

> Anyway, the "ugly" patch indeed seems to prevent plasmashell from crashing.

The output is quite suprising. It tries to use item with empty service id (Data Source). It should be something like: ":1.9/StatusNotifierItem" (as in listIcons.sh output).

In this case there two processes: plasmashell (all panels, applets, desktop etc) and kded5 (daemons with one important: StatusNotifierWatcher).

I'll attach new patch with additional logs. Can you apply, restart plasmashell (with QT_LOGGING_RULES) and try to reproduce?

After that, can you restart kded5 and try to reproduce?
killall kded5; QT_LOGGING_RULES=*kde*=true kded5 &

kded5 holds the state of Status Notifier Items (SNIs). Idea is that this state is corrupted for whatever reason with some empty items. If that's the case restart should fix it (temporarily). After restart in plasmashell logs you should see entries like:
kde.dataengine.sni: Service "org.kde.StatusNotifierWatcher" status change, old owner: "" new: ":1.144"
kde.dataengine.sni: Registering ":1.125/org/ayatana/NotificationItem/discord1"

I'd certainly prefer to get it fixed properly. As long as you're not fed up with me yet, I'm happy to cooperate.

So you want me to undo that "ugly" patch, apply the new one, restart with the logging enabled, try to trigger the crash and post the log? Although looking at the new patch the "ugly" code seems still there, so I shouldn't be able to reproduce the crash. So I guess you just want the extended log, with an attempt to start up e.g. ktorrent or so?

My bad, I was not clear. Attempt is enough, just to get "No DataContainer for" log message. Plasma would crash at that moment, now it just logs unexpected state.

Added the two logs. Hope I got it right - both are after restarting plasmashell or kded5 with logging and then starting up ktorrent.

Can you also add plasmashell logs after kded5 restart?

I haven't restarted either plasmashell or kded5 again. Hope that's what you meant.

patch: workaround + even more logs

It was useful, thank you. Are all the expected icons correctly rendered? In listIcons.sh output there are several icons like KMail, KMix etc - are all of them visible and working? Do you have any empty space in Entries section of System Tray settings (probably at the end of list)?

I've added new patch with even more logging - can you apply, start plasma, start Ktorrent and attach logs? As before, try to reproduce the issue with "No Data source for" log.

patch: workaround + logs attempt3

This is super strange...

To recheck: before starting of KTorrent (just after plasmashell restart)  everything should look fine: you should see all items in System Tray setting with no empty row.
After running KTorrent you should see empty rows in setting and few icons missing (KMix, KMail). After kded5 restart you should around 5 or 6 empty rows and KMix, KMail etc visible again.

To summarize what I found:
In System There is an internal list of SNI items with service id + StatusNotifierItemService pointer. You can see it as Item(...) in logs. Everything looks fine until you start new application - existing items in the list are for whatever reason cleared! Service id is empty (""). This of course breaks everything. I still don't know why...

Just to double check, can you apply attached patch (revert earlier patches)? It will log state just before item add and just after.

One more test: it seems that on start you have exactly 6 SNI icons (KMix, KMail, Kwallet etc). Can you close two of them, restart plasmashell, run something (for example KTorrent) and check logs? Is there "No DataSource for"? If not, start more apps with icons (can be these two you closed before start). This is to check if 6 is important (it is an initial capacity of the internal list).

This seems to be correct.

Yes, those empty rows in system tray settings windows are now actually even all over the place - see the attached screenshot.

Yes, this recovers the icons in the systray but those empty items in system tray settings are still there.

Done - see the attached log called " Plasma shell extended logging 2".

There are those "No DataContainer for" (I'm guessing you meant that and not "No DataSource for") after restarting Plasmashell, but not after starting up one app after that.

Yeah, all the hell seems to break loose once I start the +1 app. There are some more "No DataContainer for" messages and some icons disappear from the sys tray and there are suddenly those empty items in System Tray settings.

testVector.zip

So the problem is around:
m_items.append(item);
when QVector changes capacity beyond 6... After this operation QString in old items is empty. I don't know why this happens :(

I attached very simple test application that does similar thing. I guess it will work correctly but worth a try.

Does your problem happen if you remove second system tray? Or on entirely fresh user? Can you try different scenarios? I'm completely out of clues :(

I'm going to attach output of that test application below. There were none of those "something went wrong" messages so I guess it worked correctly?

> Does your problem happen if you remove second system tray?
Removing the second system tray didn't change anything - I still get those empty system tray items once I startup an extra app.

> Or on entirely fresh user?
I was able to reproduce it (after some persuading) even for a fresh user.

> Can you try different scenarios? I'm completely out of clues :(
Don't worry about it.

I've been thinking... would it make any sense for me to try to debug it myself? I mean going step by step over the code, watching the data structure that holds the systray data along the way and waiting for it to get broken at some point? I'd obviously need a nudge in the right direction from you as to where in the code to start etc. But I'm a bit of a developer myself (mostly just PHP these days), even though I haven't touched c/c++ in a quite some time and don't believe I've ever done any sort of debugging in gdb yet. So I thought this might work.

What do you think - does it sound feasible to you? Or way too much effort and skill required? Or not even possible to do it like this?

That would be the only feasible way :)

the problem is around line:
m_items.append(item);
in SystemTrayModel. Unfortunately somewhere inside QVector implementation. Initially QVector has very low capacity (to save memory), when one adds more items more memory is allocated (0 -> 2 -> 6 -> 14 -> 30 -> 62...). Your problem occurs when capacity goes from 6 to 14 - probably QString "source" is wrongly moved which ends in empty string (""). Test vector app does exactly the same QVector resizing but it works correctly...

It is very unlikely that this is a problem in Qt library, it is used by thousands if not millions, this kind of issue would be detected long time ago. So must be a problem with QVector usage. I wrote this code (SystemTrayModel) but I'm not an C++ expert (mostly Java). Probably there is non-obvious but trivial things that should be added.

There are few things you can check:

* this is my best guess, in systemtraymodel.h add:
Q_DECLARE_TYPEINFO(StatusNotifierModel::Item, Q_MOVABLE_TYPE);
StatusNotifierModel::Item must be public - it is after my last patch, but you can do better and:

* move struct Item outside of StatusNotifierModel. In cpp file usage would be just Item, instead of StatusNotifierModel::Item. you can change struct name to something like struct StatusNotifierModelItem

* add deep copy when assigning item.source (this should never be need, only to test if there is a problem with data sharing in Qt):
#include <QDeepCopy>
item.source = QDeepCopy(sourceName);

* this is ugly hack, but you can allocate bigger space for m_items in constructor of SystemTrayModel:
    m_items.resize(1000);
    m_items.clear();
this is unacceptable in production code but can confirm my hypothesis about QVector resize (and bad reallocation)

Alright, great and thanks for all the tips!

Hopefully last two questions, then I'll finally leave you alone. At least until I can come up with something interesting myself, that is:

- so I guess in order to be able to debug stuff I need to rebuild the whole KDE set with CMAKE_BUILD_TYPE=Debug, right?

- then I should be able to run plasmashell through gdb, put breakpoints in the code, trace it line by line etc.?

IIRC by default it is RELWITHDEBINFO. You had debug symbols in crash report so default should be fine.

Probably not needed, we know the line which cases the problem, including state before and after (all items are logged). You can just apply more changes and check logs - IMO that the fastest way.

Hey,

I'd like to just for the record wrap this up a little by stating that this whole "bug" of mine was most likely caused by my somewhat old-ish compiler version (gcc 8.2) somehow producing a broken code. After upgrading to gcc 10.2 this whole issue just disappeared - I've been using Plasma 5.21 built with it on three different machines now for a few weeks without a single crash.

Again sorry for wasting anyone's time on this.

Regards

Vaclav
