If you have a frozen gem with unfrozen dependencies (for instance if the
dependency has native extensions so can't be frozen) you can have a
nightmare upgrade problem, where you cannot rake gems:install, because
rake is broken by a gem loading problem.
If you bump up your frozen gem to a newer version that requires a newer
dependency, everybody else on the team will have rake broken by that
dependency mismatch, since you will have had to specify the dependency
in your config.gems, otherwise nobody will have installed it, since the
parent is frozen. And now the config.gems loading code will kill rake.

This commit adds a rudimentary check for 'unbuilt' gems, so that we can abort
the application load if there are any gems that have native components that
have not yet been built.
The rake task gems:build has now only builds 'unbuilt' gems as a result.
The rake task gems:build:force has been added to deal with cases of incomplete
builds, or any case where you need to force the build of all of your gems.
Changes the gems:build task to get its gem list by parsing directory entries
in vendor/gems, which sidesteps the chicken/egg issues involved with having a
gem unpacked into vendor/gems without before its native bits are compiled.

Resolved all the conflicts since 2.3.0 -> HEAD. Following is a list
of commits that could not be applied cleanly or are obviated with the
abstract_controller refactor. They all need to be revisited to ensure
that fixes made in 2.3 do not reappear in 3.0:
2259ecf368e6a6715966f69216e3ee86bf1a82a7
AR not available
* This will be reimplemented with ActionORM or equivalent
06182ea02e92afad579998aa80144588e8865ac3
implicitly rendering a js response should not use the default layout
[#1844 state:resolved]
* This will be handled generically
893e9eb99504705419ad6edac14d00e71cef5f12
Improve view rendering performance in development mode and reinstate
template recompiling in production [#1909 state:resolved]
* We will need to reimplement rails-dev-boost on top of the refactor;
the changes here are very implementation specific and cannot be
cleanly applied. The following commits are implicated:

workaround for picking layouts based on wrong view_paths
[#1974 state:resolved]
* The specifics of this commit no longer apply. Since it is a two-line
commit, we will reimplement this change.
8c5cc66a831aadb159f3daaffa4208064c30af0e
make action_controller/layouts pick templates from the current instance's
view_paths instead of the class view_paths [#1974 state:resolved]
* This does not apply at all. It should be trivial to apply the feature
to the reimplemented ActionController::Base.
87e8b162463f13bd50d27398f020769460a770e3
fix HTML fallback for explicit templates [#2052 state:resolved]
* There were a number of patches related to this that simply compounded
each other. Basically none of them apply cleanly, and the underlying
issue needs to be revisited. After discussing the underlying problem
with Koz, we will defer these fixes for further discussion.
The patch also fixes:
* Fixes the chicken/egg problem present in the current gem system when
gems are defined in the config that are not yet installed.
* Remove the need to have hoe as a dependency of your production app.
* Makes the gem 'unpacking' system a lot less fragile.

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`
