Yet another infinite pacman sync (help I want to go to bed)

Issues & Assistance
1

Hey there,
I've just been trying to update my system, but pacman seems to sync all filesystems indefinitely.
There are no dmesg errors indicating issues, but in the console I can see a lot of anannicy infos:

This has been scrolling through journalctl for about 20 minutes now, and this is definitely not supposed to be happening. Is it a bad idea to kill pacman? I really want to shut off my pc for the night and thus I don't have a lot time.

While writing this I just got crash info in journalctl:

How do I stop this process?
Thanks!

I might end up killing pacman, and restoring a backup, but that always wipes login cookies in brave when I'm on wayfire for some reason

EDIT: I did not manage to kill pacman for some reason, but I was able to just poweroff my machine. I expected it to interrupt the shutdown process as you can't ctrl+c it, but apparently I am wrong.
I just btrfs-checked my root drive and it seems fine, so I assume that it's working well. If any packages are broken I might notice that, but until then, I will not restore a backup

3

With the amount of time you waited, you shouldn't be facing any issues with broken packages. All those changes were probably already written to disk. I wonder what caused the issue though!

4

All the ananicy info makes me believe that it's envolved with this, I might try to disable it and sync afterwards

EDIT: I am unsure, but it might actually be related to ananicy. I stopped it and now the sync seems faster. Next time I update my system I'm gonna try it without ananicy. This program, while increasing performance seems to cause quite some issues - first the wayland issue and now this.

5

I am pretty sure this is related to ananicy-cpp. I have disabled the service since I had these problems and the syncs appear to be faster. There are some ~1 min syncs with bigger packages, but no more infinite ones.
