Gnome 40.1 crashes when enabling material-shell

[arnarg]

trafficstars

Describe the bug I'm trying to enable material-shell (v40.a) on gnome 40.1 but every time it crashes gnome altogether. In order to figure out where in the code gnome was crashing I put log test probes all over the code and watch the journal for gnome-shell to see how far it got. This is the patch. Interestingly enough as I added more log statements it became harder to get gnome to crash, indicating (to me) that this might be some kind of race condition (as the log statements take some time). Sometimes the extension enabled just fine and sometimes gnome shell crashed but when restarting it material-shell would work. Without the logs there is no way to make material-shell work. With the patch I pasted above I get to Point 220 before it crashes, but it takes multiple tries of enabling and disabling it to actually get gnome shell to crash with all these test probes.

Expected behavior Material-shell should work just fine when I enable the extension on gnome 40.1

To Reproduce

• Occurs on:
  • [ ] X.Org

Some code accessed the property 'ENABLED_EXTENSIONS_KEY' on the module 'extensionSystem'. That property was defined with 'let' or 'const' inside the module. This was previously supported, but is not correct according to the ES6 standard. Any symbols to be exported from a module must be defined with 'var'. The property access will work as previously for the time being, but please fix your code anyway.

Is there any less crude way of debugging what exactly might be causing this issue?

[PapyElGringo]

Any other extensions enabled?

[arnarg]

No.

[PapyElGringo]

3.40.1 isn't a valid gnome version but I don't think it's related

[PapyElGringo]

Could you get the coredump stack?

[arnarg]

3.40.1 isn't a valid gnome version but I don't think it's related

I just appended whatever I got from gnome-shell --version to the 3 to be honest.

Could you get the coredump stack?

I did not attempt this. I will try it later today. What would be the best way of doing this?

Gnome crashes for me every time I try to enable material-shell using the NixOS 21.05/Gnome 40.1/X.Org/https://github.com/material-shell/material-shell/commit/fa59ef898a2eed88259b64558eb2d4f837cdc267, but it works with @arnarg logging patch applied :eyes: :see_no_evil:

[VanCoding]

yep, same here on my NixOS System.

[SapphicCode]

Yep.

❯ nixos-version 
21.05.1105.6613a30c5e3 (Okapi)

~ 
❯ gnome-shell --version
GNOME Shell 40.1

I dunno, at this point it seems like the blame might lie with NixOS.

[matesitox]

Confirmed on nixos 21.05.3367.fd8a7fd07da (Okapi) & GNOME Shell 40.1 Anyway I can help debug this issue? @arnarg The link to your logging patches seems dead, could you reupload those?

[gilescope]

Same here but I'm on X11 so that rules some stuff out.

[Gistbatch]

I have this issue on 22.05.2065.9370544d849 (Quokka), Gnome Shell 42.3.1 Wayland. I would love to help depugging but someone has to point me in the right direction as I'm quite new to NixOS
