swhkd doesn't start: Os Error, Function not implemented

[loiccoyle]

Version Information:

• Distribution Information ( run uname -a ):
  Linux FrameWork 5.16.11-arch1-1 #1 SMP PREEMPT Thu, 24 Feb 2022 02:18:20 +0000 x86_64 GNU/Linux
• swhkd version ( swhkd -V )
  swhkd 1.0.0

Describe the bug:
I installed from the AUR (swhkd-git), when I try to run start the daemon I get the following error msg:

$ swhks &
$ pkexec swhkd -c ~/.config/swhkd/swhkdrc
[2022-03-02T00:49:56Z WARN  swhkd] Running swhkd as root!
Error: Os { code: 38, kind: Unsupported, message: "Function not implemented" }

Expected behavior:
The daemon to start succefully.

Actual behavior:
Daemon doesn't start and crashes.

To Reproduce:

$ paru -S swhkd
$ swhks &
$ pkexec swhkd -c ~/.config/swhkd/swhkdrc

I also tried installing straight from the github:

$ git clone https://github.com/waycrate/swhkd
$ cd swhkd
$ git rev-parse HEAD
3986dd01a31c168e91a3de038911745293dfa574
$ make setup
$ make glibc
$ sudo make install

But the same crash happens.

Hm this is quite the odd bug.

[Shinyzenith]

@vainiovano Could this possibly have something to do with tokio?

[vainiovano]

Probably, but I can't reproduce this.

[Shinyzenith]

Its failing here

@loiccoyle Hi! try cloning the repo to some directory and then run git checkout -q d413ac820ad6c288da96363e1af76a22964ffcb1. Then recompile and install. If it works after that then it means that tokio is the reason for the problem.

I just did that and no crash!

[Shinyzenith]

@vainiovano definitely a tokio bug then^ would you mind taking a look?

[vainiovano]

@loiccoyle could you run the command with strace or something similar and send the output? "Function not implemented" is the error message for ENOSYS, but I have no idea what causes that.

[Shinyzenith]

I think one of these 3 are causing it.

[Shinyzenith]

Since it's not a thread panic, meaning it's not a hard crash and probably a soft one introduced by one of the ?.

[Shinyzenith]

Since ENOSYS is a libc error, I think it boils down to the first arrow in the image.

[Shinyzenith]

Oh! @loiccoyle can you try swhkd-musl-git from the AUR? since it will be dynamically linked, we rule out bugs in our codebase with it.
If it works it will indicate that the bug has something to do with your glibc version.

[loiccoyle]

Here is the strace.

swhkd_strace.txt

oh and @loiccoyle while you're at it, would you mind checking if your system is uptodate?

Yep fully up to date.

Same behaviour.

[vainiovano]

@loiccoyle Does #62 fix this?

[Shinyzenith]

Closed by mistake, @loiccoyle try a recompile from main and let us know.

[loiccoyle]

Yep it works ! Thanks!

[Shinyzenith]

Sweet.

[Shinyzenith]

Thank you @vainiovano <3
