Description David REVOY 2021-10-28 01:06:41 UTC
Hi, Here is a (random) crash while painting with a recent Krita Plus build; appimage. Version: 5.0.0-beta2 (git 188e619). A very solid appimage; first crash in last days. I collected a backtrace; but I'm not sure if it is a revelant one. 
I hope it will help!

Comment 2 sh_zam 2021-10-29 07:54:50 UTC
Hi!

The crash in both cases seem to happen inside Qt, which sadly doesn't give any idea what might be the reason :(
Comment 3 David REVOY 2021-10-29 17:37:04 UTC
Hi @Sh_Zam, thanks for having a look.

As I continue to get crash, I'll continue to paste them here, maybe the backtrace of one will be a bit more talkative than previous ones. Here the one I just get while drawing:

Comment 7 Tiar 2021-11-03 23:00:09 UTC
What I noticed is "copyOriginalToProjection" and "applyMasks". @David can you please tell what kind of masks are you using? Could you please try painting without masks, if it's possible (to see if it will still crash so often)?

Also it mentions undo, It looks a bit as if one thread tried to lock the painting because it's undoing stuff, and another thread tries to lock the painting because it's trying to apply the mask. Can you please say if it's possible that the crash happens when you undo while painting on a mask?

I wonder if it wouldn't be Emmet & Eoin's regression because they were playing with the order of writing stuff in and out because of changes in animation.

PS. @David, if you report something important, like a crash that happens often, something we couldn't possibly release Krita with, please add "regression" (if it's a regression) and "release_blocker" keywords (if you can. If you can't, I'll talk to halla if you couldn't have higher permissions). Otherwise it might get lost/forgotten :/ If you make a mistake and the bug is not as important, that's not a problem, someone can change it back. But if something important is forgotten, that's a more serious issue.

Also I'm confirming because there is plenty of backtraces here.
Comment 8 David REVOY 2021-11-04 17:50:41 UTC
> Could you please try painting without masks, if it's possible (to see if it will still crash so often)?

@Tiar: Mmm, my layer stacks on my comic pages doesn't contain any masks. I have a vector layer (on top for the panel, just rectangle filled with white), and I also have a File Layer on top that display an external PNG export of the speechbubbles/txt done with Inkscape. Execpt that, I have a root group layer /, and usual paint-layer.

I'll keep an eyes on the layer stack if I have new crashes in the middle of drawing.
Comment 9 David REVOY 2021-11-05 01:38:45 UTC
A new crash while painting (no mask, no undo, just drawing on regular paint-layer). I'm copying here only the irregular thread output, it will be shorter and probably better:

Comment 10 Tiar 2021-11-05 01:39:56 UTC
Hmm, maybe it was a Global Selection Mask, then? (It doesn't need to show on the Layer stack, it's hidden by default, but it is there if you have anything selected). Maybe you were editing a selection and undoing?... How do you usually change selections?
Comment 11 David REVOY 2021-11-05 02:01:06 UTC
@tiar: All the crashes backtrace here are really happening in middle of stroke of brush with the freehand brush tool. (while penciling or inking). 

I do selection rarely when repositioning things with the transform tool (but this is happening more at storyboard time); in this case I manage all by keyboard (a key for the lasso or rectangular tool, Ctrl+T for the transform, Enter to bake the result, deselect and B to repaint). But I never had a crash within this type of sequence. 

I also rarely undo while penciling or inking. I use a slot of the Ten Brush plugin binded to an eraser preset; and I pencil or ink with a preset and toggle switch with this shortcut to an eraser when I need to clean.  I rarely stop when a line is bad; I just trace the good one next to it, and switch to eraser later in the process to do a mass cleaning of "wrong lines". It saves time.  I'm on 15 pages episode with 84 panels doing similar workflow over and over :-) I'm inking page 9 right now. 

Fortunately, autosave is doing a good job and I rarely loose more than 3 minutes.
Comment 12 sh_zam 2021-11-08 12:50:59 UTC
Hi David!

Looks like this crash needs some manual intervention in the gdb to narrow down
the area to debug.

Here’s what I’d do if Krita crashed, to get some insight. It may or may not
help much…

Inside gdb:

(gdb) info registers       # to get info about the state
(gdb) set pagination off   # to print everything without stopping
(gdb) disassemble          # print disassembly of the frame

Note: It is possible that the disassemble output may be way too much, in that
case you may find it convenient to attach it as a file instead :)

Comment 18 Tiar 2021-11-14 01:08:09 UTC
@David, to get a more useful console output, please create a file called `.gdbinit` in your home directory with this line:
`set print thread-events off`
It will remove all those annoying `[New Thread 0x7fff2a37a700 (LWP 284671)]` and leave just things either Krita or Qt print out, mostly warnings or some config info. It also shows all asserts and safe asserts.
Safe asserts might also appear in Help -> Show Krita log for bug reports, can you please check it? You probably should scroll to the very bottom.
-------

`Still unsignalled after processed 129 tiles` that actually sounds worrying, maybe @Dmitry will know what's up with that. 
That line was added only recently, two months ago, in this commit: 
https://invent.kde.org/graphics/krita/-/commit/191e0da9d2a4770f996b89f8e657eef90a79e207
> Proof of concept implementation of multibuffered tile uploading

-------
Since it's related to OpenGL, @David does the crash happen every time you paint, or maybe so often that you'd notice if it doesn't crash? If so, can you please try 1) without "Use Texture Buffer" in Display -> Canvas Acceleration; and 2) without Graphics Acceleration altogether, and see if it crashes then as well?

I'm assigning Dmitry, thoush maybe someone else, like Amyspark or Ivanyossi, could help too.
Comment 19 David REVOY 2021-11-14 13:18:34 UTC
Hey @Tiar, ok, I'll add the .gdbinit option and see what info I can fish this way. I'll continue the investigation!  :-) Thanks.

About the frequency; I get here the crash daily in general, or twice. But I'm also spending more than 14h each day painting (I'll release beta of Pepper&Carrot ep36 next week, a massive15 pages episode that end book 4. I entered in "pre-color" this week, all was penciled, inked,etc... ).

Krita log + command line log

Hey, so I got the crash again and could catch the Krita log and what happened in the command line (in attachement). 
In short; I had:
   Still unsignalled after processed 129 tiles
       increased number of buffers to 256
   Bus error
Not really useful, I guess.
Comment 21 Dmitry Kazakov 2021-11-16 07:12:53 UTC
Hm.. the crash logs look really weird. Here is what I can tell from inspecting them:

1) "Still unsignalled after processed 129 tiles" should not be related to the crash. It is just a debug notification, we should probably hide it from the release.
2) The crash happens in the GUI thread, most probably, due to a memory corruption (see fluctuations between SIGSEGV and SIGBUS)
3) This memory corruption happens long before the actual crash
4) In at least 4 crashes of 12, the worker tread has been working on ending the stroke (destroying the brushes and superseded undo commands). That might be related actually.

I will make a build with ASAN, so David could catch then actual memory corruption :)
Comment 22 Dmitry Kazakov 2021-11-16 09:54:48 UTC
Hi, David!

Could you please try to reproduce this test with this AppImage?

https://disk.yandex.ru/d/1qQgbrSt8vBmGw

This AppImage has ASAN checks enabled, it means it will crash as soon as any invalid memory access happens. It will dump the report into the terminal.

Short instructions:

1) Run it in terminal, that is were it will dump the log
2) Do **not** run it under GDB, it has everything embedded into the package
3) When it crashes, copy the log that it dumps into the terminal
Comment 23 Dmitry Kazakov 2021-11-16 11:41:54 UTC
Hi, David!

I'm not sure this AppImage actually has ASAN debugging, please don't spend time on that until further clearance.
Comment 24 Dmitry Kazakov 2021-11-16 11:49:44 UTC
I'm sorry, the package is okay, you can test it :)

Backtrace with ASAN build

Thanks for the appimage @dmitryk, as I told on IRC; this one is not comfortable to use: glitch with refresh of layers within groups, performances are slow, no GMIC, and I noticed also my KPL palettes unable to load. Hard to keep it in production but I do the effort :-P 

Anyway: I could reproduce a crash after probably 8h painting and save the terminal output, I attached it here. I hope I caught a good fish :-)
Comment 26 Dmitry Kazakov 2021-11-17 10:16:15 UTC
Hi, David!

The backtrace shows that the problem happened when you tried to switch a visibility (or some other) property of the layer that has been removed (right before or after that). Do you remember doing something like that? Perhaps you changed visibility of some layer and then pressed Ctrl+E to merge them?

PS:
This seemingly unrelated issue can really be a cause of the original "crash on painting" problem, because without ASAN it would corrupt the memory.
Comment 27 Dmitry Kazakov 2021-11-17 10:39:50 UTC
I can reproduce this ASAN crash with the following steps:

1) Create to layers, "layer 1" and "layer 2". "layer 2" is above "layer 1"
2) Start clicking on visibility button of "layer 2" in non-stop mode
3) At the same time press Ctrl+E shortcut

Now we just need to confirm that David did somewhat the same steps as I do :)
Comment 28 Dmitry Kazakov 2021-11-17 11:23:42 UTC
Correction, you should click on "layer 1", while "layer 2" is selected.
Comment 29 David REVOY 2021-11-17 13:29:49 UTC
Hey Dmitry! 

> Perhaps you changed visibility of some layer and then pressed Ctrl+E to merge them?

BINGO! 👍 I think you found something I do very often, and I think I made a big cleaning on the layer stack before the last crash, so it is very likely it's the origin of the crash :-) 

Workflow note: I usually try to improve my paintings by duplicating the layer I'm working on, and then −after painting a bit− I compare with layer under (visibility) before merging down (if the change looks good). That's a bit my 'create branch' + 'merge to master' system in layer stack. And I *really* do that all the time, like every 10 min over all the days.

Reproducability: I tried to reproduce the steps on a new file then on a heavy comic page, but I couldn't trigger the crash here. Maybe I did the step wrongly. 

Thank you for investigating this crash.
Comment 30 Dmitry Kazakov 2021-11-17 13:38:35 UTC
Hi, David!

Thanks for confirmation! :)

Now it is "just" left to fix this bug... which is actually deep in the design of Krita internals :(
Comment 31 David REVOY 2021-11-17 13:58:45 UTC
Argh 😆 Good luck with it.
I'll continue here to test with the ASAN appimage build in case I can get more crashes output with different causes.
Comment 32 David REVOY 2021-11-17 14:51:24 UTC
I just had another crash with ASAN, but with a much shorter output, I'll paste it here directly:

This one was obtained while 'airbrushing' an area to silhouette a character.

Committed on 19/11/2021 at 11:59.

Fix random memory corruptions when manipulating layers too quickly

It turned out, when the user switches visibility of a layer,
the event loop can be entered recursively (due to KisBusyWaitBroker),
it could lead to memory corruptions due to the broken pointers
to KisNodeDummy stored in QModelIndex objects.

The problem is fixed by forcefully syncing the node manipulation
signals to non-recursive event processing using a new
KisSynchronizedConnection class. See documentation in it for details.

Thank you very much @Dmitryk! 👍
I'll catch a recent 5.0 Krita Plus build asap and test. If I find anything, I'll open a new ticket.

Fix random memory corruptions when manipulating layers too quickly

It turned out, when the user switches visibility of a layer,
the event loop can be entered recursively (due to KisBusyWaitBroker),
it could lead to memory corruptions due to the broken pointers
to KisNodeDummy stored in QModelIndex objects.

The problem is fixed by forcefully syncing the node manipulation
signals to non-recursive event processing using a new
KisSynchronizedConnection class. See documentation in it for details.
