Pools start out empty and grow as necessary to a maximum size (default is 5, configure size with key 'pool' in your database configuration). If no connections are available, a thread will wait up to a 'wait_timeout' time (default is 5 seconds). Connections are verified and reset when checked out from the pool (usually upon first access to ActiveRecord::Base.connection), and returned back to the pool after each request. If you would like to use connection pools outside of ActionPack, there is an ActiveRecord::Base.connection_pool method that gives you access to the pool, and you can manually checkout/checkin connections, or supply a block to ActiveRecord::Base.connection_pool.with_connection which takes care of the checkout/checkin for you.

= Active Support -- Utility classes and standard library extensions from Rails Active Support is a collection of various utility classes and standard library extensions that were found useful for Rails. All these additions have hence been collected in this bundle as way to gather all that sugar that makes Ruby sweeter. == Download The latest version of Active Support can be found at * http://rubyforge.org/project/showfiles.php?group_id=182 Documentation can be found at * http://as.rubyonrails.com == Installation The preferred method of installing Active Support is through its GEM file. You'll need to have RubyGems[http://rubygems.rubyforge.org/wiki/wiki.pl] installed for that, though. If you have it, then use: % [sudo] gem install activesupport-1.0.0.gem == License Active Support is released under the MIT license. == Support The Active Support homepage is http://www.rubyonrails.com. You can find the Active Support RubyForge page at http://rubyforge.org/projects/activesupport. And as Jim from Rake says: Feel free to submit commits or feature requests. If you send a patch, remember to update the corresponding unit tests. If fact, I prefer new feature to be submitted in the form of new unit tests. For other information, feel free to ask on the ruby-talk mailing list (which is mirrored to comp.lang.ruby) or contact mailto:david@loudthinking.com.
