Whilst autoloading is known to be not threadsafe, leaving it in place is a softer solution than failing hard when an application is deployed. Many older applications will have paths added to `autoload_paths` and ideally these should be eagerly loaded to be threadsafe. However one of these paths is quite often lib which could lead to unintended consequences due to the 'junk drawer' nature of this directory. Developers should refrain from adding paths to `autoload_paths` or `eager_load_paths` and use custom folders inside app for code that needs to be eagerly loaded and use `require` or `require_dependency` to explicitly load code from other locations.
…ping with Rails 4.0.
This is an alternative implementation to #7771 thanks to the advice of @spastorino Rails is a dynamic framework that serves a static index.html by default. One of my first questions ever on IRC was solved by simply deleting my public/index.html file. This file is a source of confusion when starting as it over-rides any set "root" in the routes yet it itself is not listed in the routes. By making the page dynamic by default we can eliminate this confusion. This PR moves the static index page to an internal controller/route/view similar to `rails/info`. When someone starts a rails server, if no root is defined, this route will take over and the "dynamic" index page from rails/welcome_controller will be rendered. These routes are only added in development. If a developer defines a root in their routes, it automatically takes precedence over this route and will be rendered, with no deleting of files required. In addition to removing this source of confusion for new devs, we can now use Rails view helpers to build and render this page. While not the primary intent, the added value of "dogfooding" should not be under-estimated. The prior PR #7771 had push-back since it introduced developer facing files. This PR solves all of the same problems, but does not have any new developer facing files (it actually removes one). cc/ @wsouto, @dickeyxxx, @tyre, @ryanb, @josevalim, @maxim, @subdigital, @steveklabnik ATP Railties and Actionpack.
…mespaces The new option allows any Ruby namespace to be registered and set up for eager load. We are effectively exposing the structure existing in Rails since v3.0 for all developers in order to make their applications thread-safe and CoW friendly.
Previously, the eager load behavior was mostly coupled to config.cache_classes, however this was suboptimal since in some environments a developer may want to cache classes but not necessarily load them all on boot (for example, test env). This pull request also promotes the use of config.eager_load set to true by default in production. In the majority of the cases, this is the behavior you want since it will copy most of your app into memory on boot (which was also the previous behavior). Finally, this fix a long standing Rails bug where it was impossible to access a model in a rake task when Rails was set as thread safe.
… own consumers around stdlib's Queue
In the current router DSL, using the +match+ DSL method will match all verbs for the path to the specified endpoint. In the vast majority of cases, people are currently using +match+ when they actually mean +get+. This introduces security implications. This commit disallows calling +match+ without an HTTP verb constraint by default. To explicitly match all verbs, this commit also adds a :via => :all option to +match+. Closes #5964

…changed. This can be turned off by setting `config.reload_classes_only_on_change` to false. Extensions like Active Record should add their respective files like db/schema.rb and db/structure.sql to `config.watchable_files` if they want their changes to affect classes reloading.
