In case anyone's wondering, the TruffleRuby project is still going strong. It undoubtedly would be going stronger were Chris still with us. But, some of us that worked with Chris in the early days of the project and others that joined later are still pushing the project forward. If you're interested in the project, please give it a try. Or, if you just want to chat Ruby compilers, feel free to drop into one of our community channels (Slack or GitHub Discussions). https://github.com/truffleruby/truffleruby.
In TruffleRuby
The Rails initialization process is commonly called "booting", probably owing to the presence of the config/boot.rb file. It's the loading and execution of code necessary before a request can be processed. Beyond the code that Rails executes, it generally includes the loading of most, if not all, of your application's dependencies and any initialization they may require. In my experience, the Rails boot stage accounts for most of the compatibility work. If you can't boot the app, you won't be able to serve requests and likely can't run tests. E.g., it was at this step that we learned we needed to support more of the native extension API to get memcached running (†). Once booting we did run into some other compatibility issues, but the lion's share came up during the Rails boot process. † - As an aside, the memcached gem hasn't seen a rele

ase since 2014. Its C code attempts to detect the Ruby version and alter how it sets things up. It predates the availability of TruffleRuby so there isn't any TruffleRuby-specific detection logic in it. Our extension compatibility made it look like we supported CRuby's internal object model and that was causing the extension to try to allocate objects in a CRuby-specific way. A small change to a macro fixed the problem and the rest of the gem ran fine. It's one of those things that we can't fix until we see, but once we do we can fix it permanently.
