The way constants are set/resolved in class_eval blocks seems
to have changed significantly. Move constants to top-level to
remedy the situation for now.
* Adds test/helper.rb and moves mock_app and other code specific
to testing the framework out of Sinatra::Test.
* Do not require test/unit. The sinatra/test/unit,
sinatra/test/spec, and sinatra/test/rspec files can be used to
choose the framework.
* Add Sinatra::TestHarness, which should act similar to the
Rack::Session proposal here: http://gist.github.com/41270
* Update the README with information on using the different test
frameworks.
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.
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.
