Hello @michaeld @RGJ, Iā€™m not sure if this is the right place to ask, but Iā€™m experiencing a similar issue with ffi when using the repository at https://github.com/communiteq/discourse-siwe-auth as well as https://github.com/spruceid/discourse-siwe-auth.

Hook section of my discourse self-hosted app:

hooks:
  before_code:
    - exec:
        cmd:
          - gem install rubyzip
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/communiteq/discourse-siwe-auth.git
          - git clone https://github.com/discourse/discourse-code-review.git

For now, Iā€™m going to try forking your repository and bumping the version, as I have a deadline to migrate this Discourse instance. I just wanted to let you know about this.
Also, Iā€™d like to know if the plugin is actively maintained by Communiteq.

Thanks in advance!

Without looking at the codeā€¦

Could the problem be that ffi is now in core and your donā€™t need to add it?

44

Iā€™m not really into Ruby so I canā€™t make an statement about the plugin but I can confirm that bumping the ffi to 1.17.2 in the forked repository works like a charm, and with bumping I mean changing the plugin.rb with:

gem 'ffi', '1.17.2', require: false

That worked for me but Iā€™d really like to use the official maintained plugin instead of my own fork.

45

My suggestion was to remove the gem altogether. And when that works, submit a PR with that line removed.

46

Weā€™re more like passively maintaining it. The official repository is in spruceid, but since we run a number of sites using the plugin, in practice itā€™s us who fix it first. This time you beat us to it, it is still on our list of plugins to change for 3.5.

If no one makes a PR to the official repo, I will get to this by the end of this week or the beginning of next week.

I would prefer to leave the task of opening the PR to you, as you probably have considerations or tests regarding the plugin that I am unaware of, since I know very little about this service as I am in the process of migrating it.

Thank you for your help, information, and contributions on this topic.

I have fixed the plugin - it indeed was only a matter of removing the explicit ffi gem inclusion.

I have also made a pull request to the original repository. As long as the PR has not been accepted, you can use https://github.com/communiteq/discourse-siwe-auth instead of the original repository.

I will change the link in the OP to this for the time being as well.
