This is a comparision of handling JavaScript alert/confirm/prompt notifications with Capybara.

Proposed consolidated API in Capybara:

  There are two styles of notification handling: proactive or reactive.
    - Proactive is used in headless environments to queue up responses.
    - Reactive is used in environments with actual notifications that mandate a response (eg selenium).

  alert   - # Reactive
            page.driver.accept_alert

Zero downtime deploys with unicorn + nginx + runit + rvm + chef

Below are the actual files we use in one of our latest production applications at Agora Games to achieve zero downtime deploys with unicorn. You've probably already read the GitHub blog post on Unicorn and would like to try zero downtime deploys for your application. I hope these files and notes help. I am happy to update these files or these notes if there are comments/questions. YMMV (of course).

Other application notes:

• Our application uses MongoDB, so we don't have database migrations to worry about as with MySQL or postgresql. That does not mean that we won't have to worry about issues with the database with indexes being built in MongoDB or what have you.
• We use capistrano for deployment.

Salient points for each file:

If you're writing web applications with Ruby there comes a time when you might need something a lot simpler, or even faster, than Ruby on Rails or the Sinatra micro-framework. Enter Rack.

Rack describes itself as follows:

Rack provides a minimal interface between webservers supporting Ruby and Ruby frameworks.

Before Rack came along Ruby web frameworks all implemented their own interfaces, which made it incredibly difficult to write web servers for them, or to share code between two different frameworks. Now almost all Ruby web frameworks implement Rack, including Rails and Sinatra, meaning that these applications can now behave in a similar fashion to one another.

At it's core Rack provides a great set of tools to allow you to build the most simple web application or interface you can. Rack applications can be written in a single line of code. But we're getting ahead of ourselves a bit.

Changes:

• this version includes backport of Greg Price's patch for speedup startup http://bugs.ruby-lang.org/issues/7158 .

  ruby-core prefers his way to do thing, so that I abandon cached-lp and sorted-lf patches of mine.

• this version integrates 'array as queue' patch, which improves performance when push/shift pattern is heavily used on Array.

  This patch is accepted into trunk for Ruby 2.0 and last possible bug is found by Yui Naruse. It is used in production* for a couple of months without issues even with this bug.
