1. Don't add the sinatra lib dir to $: on each reload. 2. Don't remove sinatra.rb from $LOADED_FEATURES unless we're reloading.
This is a fairly large reworking of Sinatra's innards. Although most of the internal implementation has been modified, it provides the same basic feature set and is meant to be compatible with Sinatra 0.3.2. * The Event and EventContext classes have been removed. Sinatra applications are now defined within the class context of a Sinatra::Base subclass; each request is processed within a new instance. * Sinatra::Base can be used as a base class for multiple Rack applications within a single process and can be used as Rack middleware. * The routing and result type processing implementation has been simplified and enhanced a bit. There's a new route conditions system for things like :agent/:host matching and a request level #pass method has been added to allow an event handler to exit immediately, passing control to the next matching route. * Regular expressions may now be used in route patterns. Captures are available as an array from "params[:captures]". * The #body helper method now takes a block. The block is not evaluated until an attempt is made to read the body. * Options are now dynamically generated class attributes on the Sinatra::Base subclass (instead of OpenStruct); options are inherited by subclasses and may be overridden up the inheritance hierarchy. The Base.set manages all option related stuff. * The application file (app_file) detection heuristics are bit more sane now. This fixes some bugs with reloading and public/views directory detection. All thin / passenger issues of these type should be better now. * Error mappings are now split into to distinct layers: exception mappings and custom error pages. Exception mappings are registered with 'error(Exception)' and are run only when the app raises an exception. Custom error pages are registered with error(status_code) and are run any time the response has the status code specified. It's also possible to register an error page for a range of status codes: 'error(500..599)'. * The spec and unit testing extensions have been modified to take advantage of the ability to have multiple Sinatra applications. The Sinatra::Test module must be included within the TestCase in order to take advantage of these methods (unless the 'sinatra/compat' library has been required). * Rebuilt specs from scratch for better coverage and organization. Sinatra 3.2 unit tests have been retained under ./compat to ensure a baseline level of compatibility with previous versions; use the 'rake compat' task to run these. A large number of existing Sinatra idioms have been deprecated but continue to be supported through the 'sinatra/compat' library. * The "set_option" and "set_options" methods have been deprecated due to redundancy; use "set". * The "env" option (Sinatra::Base.env) has been renamed to "environment" and deprecated because it's too easy to confuse with the request-level Rack environment Hash (Sinatra::Base#env). * The request level "stop" method has been renamed "halt" and deprecated. This is for consistency with `throw :halt`. * The request level "entity_tag" method has been renamed "etag" and deprecated. Both versions were previously supported. * The request level "headers" method has been deprecated. Use response['Header-Name'] to access and modify response headers. * Sinatra.application is deprecated. Use Sinatra::Application instead. * Setting Sinatra.application = nil to reset an application is deprecated. You shouldn't have to reset objects anymore. * The Sinatra.default_options Hash is deprecated. Modifying this object now results in "set(key, value)" invocations on the Sinatra::Base subclass. * The "body.to_result" convention has been deprecated. * The ServerError exception has been deprecated. Any Exception is now considered a ServerError.
…natra compatable with the master/0.5 branchs of rack
Fixed how the Sinatra application's path is set. Previously it was derived exclusively from $0, but this was causing problems when running Sinatra under Rack because $0 is the web server (e.g., thin, passenger, etc) and thus Sinatra would incorrectly set things like the default views path. This fix adds a new locate_app_file method that uses a number of techniques to guess the Sinatra application's path.
The Static event handler is now instantiated with a reference back to the Sinatra app instead of using the global singleton. While here, bump streaming buffer size from 4K to 8K -- word around the campfire is that reading in 8K chunks results in a bit less IO on most modern systems.
The default :stream option value was not being picked up properly leading all calls to send_file (including those served with Static) to read the entire file into a string before sending. Further, the body was then being returned as a string, which causes Rack to iterate over the contents line-wise.
Execute the before filters before looking up the event. Makes it possible for filters to rewrite request variables such as PATH_INFO and REQUEST_METHOD and have it effect which route is chosen.
The raise_errors option was implemented as part of the default error handler making it worthless in development mode or with a custom error handler. This moves the implementation to the core dispatch method. While here, clean up the Error class a bit, making it use the options provided and pass the correct HTTP status code.
Fixes case where development error handlers show up in non-development environments when the env option is set in code instead of on the command line. For example, the following app shows the development 404 page: require 'sinatra' set :env, :production
