Random hang on exit

[coffebar]

Hyprland Version

Hyprland, built from branch main at commit 3f09b14 dirty (makefile: fixup permissions on installed binaries). Tag: v0.30.0-22-g3f09b143

Bug or Regression?

Bug

Description

I noticed that Hyprland randomly hangs on exit. Instead of exit, it blocks my computer with a black screen and I can't access tty to do something with it.

From jornalctl after reboot I see that other programs continued working in background (syncthing) while I see only black screen.

How to reproduce

Can't reproduce it manually, even on my machine.

Crash reports, logs, images, videos

I created this script to Force exit:

echo "Hyprland exit" | systemd-cat -t coffebar -p info
hyprctl dispatch exit &
sleep 10
echo "Hyprland failed to exit" | systemd-cat -t coffebar -p err
killall -9 Hyprland

I hoped that it will kill compositor when it hangs on exit (after 10 seconds).

But it didn't work. What I found in journal:

Oct 12 19:26:18 crab coffebar[115698]: Hyprland exit
Oct 12 19:26:18 crab polkitd[1182]: Unregistered Authentication Agent for unix-session:1 (system bus name :1.22, object path /org/kde/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus)
Oct 12 19:26:28 crab coffebar[115714]: Hyprland failed to exit

After that, nothing happens in logs, except the syncthing does its job as usual.

It's odd, I'm not sure what is going on here.

[FakeMichau]

Could you provide a hyprland.log file from a session where that happened?

[coffebar]

Could you provide a hyprland.log file from a session where that happened?

Because I can't access TTY, the only thing I can do is shutdown. Logs stored in /tmp/ that was cleared after reboot.

Is it possible to configure the persistence of logs in Hyprland?

UPD: it seems I can enable enable_stdout_logs and redirect stdout into some file outside /tmp/

[coffebar]

I added -9 to killall Hyprland, which allowed me to avoid rebooting due to this bug.

I added logs to the first post.

[stevenre3d]

Hi, I'm just trying hyprland for the first time and can confirm I've seen this twice now. I have very few edits to the default config, and I'm not using a DM (just calling Hyprland from .zprofile on tty1). I'm on 6.1.57-1-lts, and I don't see any Hyprland entries in my journalctl. I'll try coffebar's exit script to try and get a log out of tmp without having to reboot.

[vaxerski]

is this still happening?

[coffebar]

Yes, today it happened for me.

Here are some journals:

[vaxerski]

can you ssh to your system when it happens and provide a stacktrace with sudo gdb attach $(pidof Hyprland) and then bt -full?

oh... oh no.

[vaxerski]

check with the above

[coffebar]

I've recompiled with the latest commit and will test, thanks!

[coffebar]

Unfortunately, it didn't help. Today it happened again.
