dunst crashes periodically

[deceptikon]

I run dunst on manjaro, installed it from community packages.
Last few weeks I observe periodical crashes, as I guess, caused by Slack notifications.
Error is as following:

~>>> dunst
WARNING: No icon found in path: 'flameshot'
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 12 (X_ConfigureWindow)
Value in failed request: 0x0
Serial number of failed request: 431233
Current serial number in output stream: 431233

~ >>> dunst -v
Dunst - A customizable and lightweight notification-daemon 1.4.0 (2019-03-30)

Warning about flameshot is unrelated to crash, it occured some time before it crashed.

Will append dbus-monitor log later, when the error occurs again.

[tsipinakis]

Hi,

Can't really say why it happened from the error posted.

As you said the dbus-monitor log when it happens would be great and additionally if you can, it would also be useful to get a backtrace from the crash.
For that, ensure that you have the debug symbols installed and run dunst as gdb -ex run dunst -ex bt.

Hi Nikos,

Please let me know if I can assist in any other way

[tsipinakis]

Unfortunately that log didn't give me anything. However, looking at the code it seems like the only place that can produce a BadValue error is the window positioning logic.

Can you build tsipinakis@232b550 with make debug (make sure to make clean first to re-build all the objects) and post the output after the crash?

Also, is this something you can reliably reproduce or does it happen sporadically?

[DragonGhost7]

I get the same error, but it happens each time i use pywal for some reason

[tsipinakis]

@DragonGhost7 Can you try also try to get the debug print as I mentioned in the previous comment?
I'd also appreciate if you could run a bisect to figure out where it's coming from. I can't reproduce this myself to investigate further unfortunately.

[DragonGhost7]

Hello @tsipinakis , here are my debug log and and dbus-monitor output.

dbus-monitor.log
debug.log

I'm still not sure how to bisect it but I will be figuring out how to do it now.

[tsipinakis]

Unfortunately that log doesn't say much. What I meant was compiling from tsipinakis@232b550 that adds some extra output in order to get information relevant to this.

In a nutshell:

git clone https://github.com/tsipinakis/dunst
cd dunst
git checkout debug-log
make debug
./dunst

And post the output when the crash happens, it should hopefully provide enough information to track this down.

Additionally doing a bisect would be amazing, you can use a comment I left in a previous issue as a guide on how to do that.

[DragonGhost7]

Hello @tsipinakis , your comment was rather helpfull.
Here is the bad commit.

bisect.log

[tsipinakis]

Excuse the inactivity on this, real life caught up with me.

@DragonGhost7 Since you can reproduce this reliably as you said can you try to get a minimal pywal config that causes this so that I can reproduce this on my side as well?

[DragonGhost7]

Hello, while this time i realizes that the problem is in fact caused by xrdb.

[tsipinakis]

I figured as much given that the commit the bisect pointed at is supposed to respond to xrdb calls. Could you be specific with what xrdb command you are running?

Additionally: What's the output of xrdbxprop -root -spy while running that command?

[DragonGhost7]

I use xrdb .Xdefaults and the output of xprop -root -spy is

[tsipinakis]

The xprop output looks about what I'd expect. But at least we got a cause. I still can't reproduce this, xrdb works properly :/.

Can you clone https://github.com/tsipinakis/dunst and build from the debug-log branch and post the output(run with ./dunst -verbosity debug)? That should confirm if my earlier theory of the crash being in the window positioning logic is right.

[DragonGhost7]

I did, and here`s output

h: 0

There it is, somewhere along the drawing chain we're getting a 0 on the window height.

I'll sign off for today, I'll add some more debug output to try to narrow this down further tomorrow.

Until then, have you tried using the default dunstrc rather than your own to see if it still happens?

[DragonGhost7]

Yes i just did, and there is no issue.

[tsipinakis]

Oh, that's a bit hint can you post your dunstrc?

[DragonGhost7]

Here it is.
Also, if separator_height is changed from 0 to anything else, the issue also dissapears.

Reproduced, I'll look more into this tomorrow.

[DragonGhost7]

Thanks a lot !

[tsipinakis]

Weirdly the crash isn't inside draw() as I expected, it crashes inside get_focused_window() after a call to draw with no available notifications. I have no clue why but fixing that call seems to do it.

@DragonGhost7 Can you build tsipinakis@69a682c, confirm this fixes the issue?

[DragonGhost7]

Build functional, issue has disappeared. xrdb command doesnt crash it anymore.
