[jruby-user] Warbler 2.0.0.pre1 Released

[Joe Kutner]

I've release a 2.0.0.pre1 version of Warbler that is compatible with JRuby 9.0.0.0.pre2, but is not compatible (in theory) with anything earlier.
https://rubygems.org/gems/warbler/versions/2.0.0.pre1

The plan for Warbler 2.x is essentially the same as JRuby 9k: only supporting Ruby 2.2 onwards and some "modern" versions of Rails and other frameworks (we'll figure out the specifics as time goes on). Development will be done on the 2.x-dev branch:
https://github.com/jruby/warbler/tree/2.x-dev

The Warbler 1.x version line *will continue to be supported* for as long as JRuby 1.7.x is supported. However, it will not support JRuby 9k. It will also, probably, not support "modern" versions of Rails and such (see above). Development will continue on the master branch until 2.0.0 is released.

The 2.0.0.pre1 release is, otherwise, not that exciting. I mainly updated it to keep parity with 1.4.7 while running on JRuby 9k. Here's a summary of things:

* Removed all references to Merb (yup, you read that right)
* Removed support for Rails 2.x
* Removed support for Ruby 1.8 (yes, it's still there), 1.9, 2.0
* Removed some convoluted logic for loading bouncy castle jars

Here are some things I'm considering doing before a 2.0.0 release:

* Remove support for Rails 3.x (continue support on the Warbler 1.4.x line)
* Remove Winstone? (make way for Tomcat?)

* Upgrade all tests to use modern versions of frameworks and Gems.

* Add first-class support for cool stuff from Servlet 3.1 via jruby-rack

Here are some example apps -- all of them ready to run on Heroku ;)

Dirt Simple Rack Example:

Sinatra (using Servlet 3.1 async) Example:
https://github.com/jkutner/warbler-sinatra-example
 
Rails 4.1 Example:
https://github.com/jkutner/warbler-rails-example

Please give this a try, and let me know if you find any problems.

I'd also love to hear suggestions for improvements, new features, or other things we should be supporting.

Cheers,

Joe Kutner

Unless there is a reason that Rails 3.x will not run on JRuby9k, please don't do this. The Ruby ecosystem has a real problem working with enterprise mainly because of this aggressive policy in forcing developers to constantly upgrade libraries. 3.2 was the latest and newest release of Rails only 22 months ago.

Please don't force us to upgrade everything at the same time.

Thanks for the feedback Ari. I definitely understand the rub. And Warbler has always erred on the side of keeping support (hence the Merb and 1.8 support in 1.4.7). I plan to continue this and I don't anticipate any problems with Rails 3.2. I was just brainstorming.

I think it's totally reasonable to support, at the least, the latest 3.2.x (as long as JRuby 9k does). And I won't kill anything earlier unless we encounter problems.
