Hello friends! I work on the JRuby project, and have recently (a couple times in the past year) attempted to get Discourse running. It would mean you can run a single Discourse process for a whole site, and probably use less memory and CPU at the same time. I think it’s worth getting it to run. As…

Yes absolutely. We really want to work with JRuby, what are the current stumbling blocks?

Here’s the diff I have at the moment. This is not an exhaustive list of extensions with no JRuby support but it’s most of them. https://gist.github.com/headius/99f7a177b67d635d4783e7f7b164a3c9 Gemfile.diff diff --git a/Gemfile b/Gemfile index 3db4f98f0a..75cd7943a3 100644 --- a/Gemfile…

[图片] sam: Regarding Rhino, you got to make sure the ruby rhino with latest GitHub - mozilla/rhino: Rhino is an open-source implementation of JavaScript written entirely in Java It looks pretty silent there Commits · cowboyd/therubyrhino · GitHub . Ideally I would prefer v8, but at a minimum we w…

[图片] sam: We really want to work with JRuby Aside: can y’all share with those of us on the sidelines a little bit about why? Is the notion that JRuby would replace MRI as the default implementation for Discourse in the future if you get this working?

That certainly isn’t my goal! JRuby would always be an alternative, and in some cases it may be a better choice than MRI for larger deployments. A single JRuby instance can handle an entire server load, maxing out all cores. If you are getting to the point of running 3 or 4 or 5 MRI instances, there…
