Hello, Today, with a few days delay, we are proud to announce the release of Rack 1.1. = Rack, a modular Ruby webserver interface Rack provides a minimal, modular and adaptable interface for developing web applications in Ruby. By wrapping HTTP requests and responses in the simplest way possible, it unifies and distills the API for web servers, web frameworks, and software in between (the so-called middleware) into a single method call. The exact details of this are described in the Rack specification, which all Rack applications should conform to. == Specification changes in this release With Rack 1.1, the Rack specification (found in SPEC) changed in the following backward-incompatible ways. - Rack::VERSION has been pushed to [1,1]. - rack.logger is now specified. - The SPEC now allows subclasses of the required types. - rack.input has to be opened in binary mode. == Changes - January 3rd, 2009: Ninth public release 1.1.0. - Moved Auth::OpenID to rack-contrib. - SPEC change that relaxes Lint slightly to allow subclasses of the required types - SPEC change to document rack.input binary mode in greator detail - SPEC define optional rack.logger specification - File servers support X-Cascade header - Imported Config middleware - Imported ETag middleware - Imported Runtime middleware - Imported Sendfile middleware - New Logger and NullLogger middlewares - Added mime type for .ogv and .manifest. - Don’t squeeze PATH\_INFO slashes - Use Content-Type to determine POST params parsing - Update Rack::Utils::HTTP\_STATUS\_CODES hash - Add status code lookup utility - Response should call #to\_i on the status - Add Request#user\_agent - Request#host knows about forwared host - Return an empty string for Request#host if HTTP\_HOST and SERVER\_NAME are both missing - Allow MockRequest to accept hash params - Optimizations to HeaderHash - Refactored rackup into Rack::Server - Added Utils.build\_nested\_query to complement Utils.parse\_nested\_query - Added Utils::Multipart.build\_multipart to complement Utils::Multipart.parse\_multipart - Extracted set and delete cookie helpers into Utils so they can be used outside Response - Extract parse\_query and parse\_multipart in Request so subclasses can change their behavior - Enforce binary encoding in RewindableInput - Set correct external\_encoding for handlers that don’t use RewindableInput == Where can I get it? You can download Rack 1.1 at ``` http://chneukirchen.org/releases/rack-1.1.0.tar.gz http://rubyforge.org/projects/rack ``` Alternatively, you can checkout from the development repository with: ``` git clone git://github.com/rack/rack.git cd rack && git checkout rack-1.1 # for this release ``` == Supported web servers The included _handlers_ connect all kinds of web servers to Rack: - Mongrel - EventedMongrel - SwiftipliedMongrel - WEBrick - FCGI - CGI - SCGI - LiteSpeed - Thin These web servers include Rack handlers in their distributions: - Ebb - Fuzed - Glassfish v3 - Phusion Passenger (which is mod\_rack for Apache and for nginx) - Rainbows! - Unicorn - Zbatery Any valid Rack app will run the same on all these handlers, without changing anything. == Supported web frameworks The included _adapters_ connect Rack with existing Ruby web frameworks: - Camping These frameworks include Rack adapters in their distributions: - Camping - Coset - Halcyon - Mack - Maveric - Merb - Racktools::SimpleApplication - Ramaze - Ruby on Rails - Rum - Sinatra - Sin - Vintage - Waves - Wee - … and many others. Current links to these projects can be found at [http://wiki.ramaze.net/Home#other-frameworks](http://wiki.ramaze.net/Home#other-frameworks) == rack-contrib The plethora of useful middleware created the need for a project that collects fresh Rack middleware. rack-contrib includes a variety of add-on components for Rack and it is easy to contribute new modules. - [GitHub - rack/rack-contrib: Contributed Rack Middleware and Utilities](http://github.com/rack/rack-contrib) == Installing with RubyGems A Gem of Rack is available at [gemcutter.org](http://gemcutter.org). You can install it with: ``` gem install rack ``` I also provide a local mirror of the gems (and development snapshots) at my site: ``` gem install rack --source http://chneukirchen.org/releases/gems/ ``` == Contact Please post bugs, suggestions and patches to the bug tracker at [http://rack.lighthouseapp.com/](http://rack.lighthouseapp.com/).
