Already initialized constant in jruby-openssl

阅读更多关于 Already initialized constant in jruby-openssl

问题 When running my rails application on torquebox, I get a lot of already initialized constant: ... warnings that originate from gems/jruby-openssl-0.8.2/lib/shared/jruby-openssl.rb:16 . Is this a security problem? Is there any way to get rid of these warnings? 回答1: I could finally get rid of it by removing the gem altogether. According to this source, jruby-openssl is now directly pulled into the jruby project and is not needed anymore as gem. Thanks everyone for looking into this with me. 回答2:

Duplication of context in path for a Rails app on TorqueBox with Apache ReverseProxy

问题 I am struggling with a scenario where I have several applications to run on a singular TorqueBox instance. When defining an app and deploying it to a root ("/") context within config/torquebox.yml the application executes properly with no apparent problems. At first I believed that this was a problem with Apache reverse proxy, but now believe it is likely an issue with Rails and/or TorqueBox, yet I can't find a clear answer or reason for the issue. This configuration is as follows: config

Find out which gems require native c extensions from a Gemfile?

阅读更多关于 Find out which gems require native c extensions from a Gemfile?

问题 I just recently started shifting attention towards deploying Ruby apps atop TorqueBox which of course is built atop Jruby. Hitherto I have been basically performing a bundle install and then tackling each gem along the way to jrubydom, but I've hit a couple gems that have taken me some considerable time to resolve due to needing to reimplement large portions of them. Is there a way to invoke bundler or rubygems to run through all gems and their deps to test if they require native c extensions

JRuby deployment options that support multiple versions of JRuby

阅读更多关于 JRuby deployment options that support multiple versions of JRuby

问题 I'm looking for a way to deploy multiple JRuby apps on a single server, the apps are in different stages and hence use different versions of JRuby, in the long term it would be pretty complicated to try and sync all of the applications with all of the application servers, so I'm looking something akin to Phusion Passenger 4 in the Javaland. Apparently Passenger allows something like this, but there's no documentation available how such a setup should work. Torquebox doesn't mention this use

Using JRuby with Rails 3.2

问题 Has anyone had any success with installing Rails 3.2 and JRuby 1.6.5 on Mac OSX Lion using RVM? I'm planning on using TorqueBox with NGINX on my production server and I'm trying to mimic as much of the development technology onto my development machine as possible. I haven't gotten to install TorqueBox on my production server, and so far with my OSX RVM install I'm getting a few errors from an existing Rails 3.2 app that works fine with 1.9.2 and REE. The problem that I'm experiencing is this

Proxy requests to virtual host in by path prefix

问题 I'm running multiple Rails applications on TorqueBox. Each application is mounted on a different web context, e.g., localhost:8080/app1 and localhost:8080/app2 (configured via TorqueBox). Apache is configured to accept requests to app1.domain.com and app2.domain.com via virtual hosts. However, I'm running into problems where some application paths (form submission paths and others) expect to be preceeded by /app1 , e.g., http://app1.domain.com/app1/rest/of/path instead of the correct http:/
