Not much to go on, but I suppose some of the unsafe code in the pulse module is doing this.

huyhoang8398 · 2021-01-15T16:55:06Z

yes I think so too, sometime pulse breaks xidlehook even i added --no audio param, should we create an issue for pulseaudio?

jD91mZM2 · 2021-01-16T13:48:39Z

No, it's probably not pulseaudio's fault - It's likely my usage of it is wrong. You should not be seeing it if you don't add --not-when-audio

jD91mZM2 · 2021-02-25T10:37:22Z

Hi! How does latest master (e26137e) work for you? I was able to reproduce the issue and I think I fixed it

LordChaos73 · 2021-02-25T10:45:41Z

I've build the latest master and testing it as we speak:

17882 /home/ericd/bin/xidlehook --not-when-fullscreen --not-when-audio --timer 180 ~/.config/i3/scripts/blur-lock.sh 0

LordChaos73 · 2021-02-25T11:31:05Z

Seems to work fine on my side; will you release a new version so we can notify the AUR packager?

huyhoang8398 · 2021-02-26T00:05:25Z

I've build the latest version and test it, it works fine for me

LordChaos73 · 2021-02-26T09:47:24Z

Unfortunately, this version also dumps core, but strangely enough there's little info:

Unfortunately, this version also dumps core, but strangely enough there's little info:

These messages seem to contradict each other @LordChaos73. What is the status of the git version, is it working and ready to be released or not?

The lack of stack trace could be because you ran strip on the binary. Are you installing it through AUR or something? That could result in stripped binaries.

LordChaos73 · 2021-03-01T10:55:10Z

I just cloned the repo from github and built the binary with cargo --build release.

LordChaos73 · 2021-03-01T11:21:07Z

I noticed the master branch was updated, I've rebuild the binary and I'm testing it again.

jD91mZM2 · 2021-03-01T12:20:05Z

Try building without --release, that should give you more info

LordChaos73 · 2021-03-01T12:53:47Z

I've done that and I'm testing the new binary as we speak. Will keep you updated.

jD91mZM2 · 2021-03-01T15:24:25Z

Did you build without --release? Very strange that it wouldn't give you any additional information :/

LordChaos73 · 2021-03-01T16:13:11Z

Yes, I build it with cargo build. The binary grew from 12M to 46M. I killed the process and restarted it again.

jD91mZM2 · 2021-03-01T21:38:05Z

I don't know... Not sure how to gather more information here. Do you have pulseaudio up and running?

LordChaos73 · 2021-03-01T23:05:47Z

Yes, pulseaudio is up-and-running on my system:

libcanberra-pulse 0.30+2+gc0620e4-3
libpulse 14.2-2
pulseaudio 14.2-2
pulseaudio-bluetooth 14.2-2

LordChaos73 · 2021-03-02T10:27:14Z

I did some more testing, when playing audio (spotify) the screen is locked regardless, so it seems xidlehook it isn't detecting it. I haven't had a coredump for a while now. I'm running the binary from the master, not the AUR one.
I do see issues regarding pulseaudio & the kernel popping up, so this might be related to the 5.11 kernel I'm running. Maybe I should try the LTS kernel as well.

LordChaos73 · 2021-03-02T10:36:04Z

Disregard my previous post; the screen got locked because my monitor went to sleep, which killed the HDMI audio. So detecting sound seems to work fine. I haven't had a coredump in the past 20 hours, so it is all good so far.

jD91mZM2 · 2021-03-02T11:24:53Z

Are you running xidlehook normally or via systemd? I've had users have issues with systemd in the past

LordChaos73 · 2021-03-02T16:35:48Z

xidlehook is started by i3:

exec --no-startup-id ~/.config/i3/scripts/xidlehook.sh

#!/usr/bin/env bash

HOME=/home/ericd

# start xidlehook only if it's not running yet
if [[ $(pgrep -i xidlehook) ]]; then
    # xidlehook is already running; just exit
    exit 0
else
    # start xidlehook
    $HOME/bin/xidlehook --not-when-fullscreen --not-when-audio --timer 180 '~/.config/i3/scripts/blur-lock.sh' 0
fi

LordChaos73 · 2021-03-03T13:31:46Z

The current version of master is already much more stable compared to the version in the AUR, I haven't had a coredump in a while. So to me it makes sense to push a new release.

jD91mZM2 · 2021-03-04T13:21:10Z

released :)

huyhoang8398 · 2021-03-04T13:36:58Z

great work! waiting for AUR update

LordChaos73 · 2021-03-17T12:45:04Z

Unfortunately I still get quite a few coredumps, especially when using the 5.11 kernel. When I was using the 5.10 LTS kernel, I almost had no coredumps from xidlehook. Unfortunately, I have no clue how I can debug this further.
