Got error "vips_cache_operation_build : stack level too deep (SystemStackError)"

[scalastic]

Hi,

Context

• I'm developing a Jekyll website which uses jekyll_picture_tag plugins which in turn uses vips.
• I'm using helaili/jekyll-action@v2 to build and deploy on GitHub Pages

Also before using jekyll_picture_tag and vips, the build and deployment were working fine, locally and with GitHub Action.

What happened

Since I integrate jekyll_picture_tag and vips:

• On local builds, everything's working.
• On GitHub Action (to deploy on GitHub Pages), I see this error :

1. You can find the complete logs at https://gist.github.com/scalastic/1e164af3fe32ec72dbc9dee3eb0d1787

Thanks for any help!

Hi @scalastic, wow, I've not seen that before.

From the stack trace it looks like ruby-vips has pushed it over the edge, but it's actually jekyll that's filled most of the stack. Have you tried asking there?

[scalastic]

Hi @jcupitt,
Not yet, I'm trying to investigate first... and you (as ruby-vips) were the first on the list ;)
Thanks for the response: I gonna try increasing ulimit too.

Hi @jcupitt,

For complete information, I've made a test case to reproduce the problem at https://github.com/scalastic/jekyll-test-cases/ if you want to have a look.

I've also created 2 issues to related projects:

• Avif generates Liquid Exception: stack level too deep (SystemStackError) rbuchberger/jekyll_picture_tag#249
• Liquid Exception: stack level too deep (SystemStackError) helaili/jekyll-action#93

Feel free to participate if you think that would be useful.
Thanks

Finally found a new and working GitHub Actions that uses ArchLinux distribution which contains a complete libvips (AVIF, WebP, JPEG,...). You can find it at https://github.com/jeffreytse/jekyll-deploy-action

I used it on my own Jekyll site and it works great.
