Instead of calling super to pass the request on, return a 404.
The modified app looks like this:
# app/metal/poller.rb
class Poller
def self.call(env)
if env["PATH_INFO"] =~ /^\/poller/
[200, {"Content-Type" => "text/html"}, "Hello, World!"]
else
[404, {"Content-Type" => "text/html"}, "Not Found"]
end
end
end
But you aren't locked in to just Rails:
# app/metal/api.rb
require 'sinatra'
Sinatra::Application.default_options.merge!(:run => false, :env => :production)
Api = Sinatra.application unless defined? Api
get '/interesting/new/ideas' do
'Hello Sinatra!'
end
# app/metal/poller.rb
class Poller < Rails::Rack::Metal
def call(env)
if env["PATH_INFO"] =~ /^\/poller/
[200, {"Content-Type" => "application/json"}, Message.recent.to_json]
else
super
end
end
end
* There is a generator to help you get started
`script/generate metal poller`
* Also, metal bits can be ran standalone with rackup
`rackup app/metal/poller.rb`
* Rails::GemDependency was missing definitions for hash and eql?, causing Array#uniq to not work.
* If several versions of a gem are unpacked in vendor, now chooses the highest if no version is specified.
* streamlined add_load_path. Now sets up Rubygems correctly to allow 'gem' to find frozen gems, with
gems frozen to vendor/gems and specifications in vendor/gems/<gem-name>/.specification
* Rails::GemDependency#specification would return a spec for the highest installed version, even for
frozen gems and/or previously loaded lower versions. See in part ticket #1123.
* removed vendor from default_load_paths - it was causing autoloading to append Gems::Gems::<gem-dir> to
constant names
* added additional tests for loading frozen gems.
* incorporates the fix from #1107 for vendor rails
* defers to freeze:gems for handling the Rails framework. gems:unpack WILL NOT place a copy of Rails
in vendor/gems. Should close#1123 completely.
* incorporates, via using the gem loader for frozen gems, fixes corresponding to #227, #324, #362, #527, and #742.
* gem plugins now work the same whether frozen or not. Correctness of the behavior is a matter for another ticket...

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.

This is needed because the existance of the ActiveSupport
constant by itself does not guarantee that the whole library
has been loaded.
Also load the StringInquirer in the Rails#env method as
the it might be called inside the initializer block
before activesupport itself has been loaded.
Changed Rails::Initializer to sort files before eager loading them. This ensures that
any files in a parent directory will be loaded before files in a subdirectory of the
'same' name. i.e. zoo.rb will be loaded before zoo/reptile_house.rb
