In the text there is a section about how to serve the assets with
far-future headers. The snippet that is proposed doesn't work on Ubuntu
11 (probably others) as mod_expires is not enabled out-of-the-box. I
noted this, and gave an example of how to load mod_expires with a2enmod.
We need to anchor to remove the extension. In addition to
be the correct way to do that, files in ~/.rbenv get that
.rb removed, so it is a real source of bugs, as reported in
b33700f558 (commitcomment-1781840)
Changes in old branches needed to be manually synched in CHANGELOGs of newer ones.
This has proven to be brittle, sometimes one just forgets this manual step.
With this commit we switch to CHANGELOGs per branch. When a new major version is
cut from master, the CHANGELOGs in master start being blank.
A link to the CHANGELOG of the previous branch allows anyone interested to
follow the history.
Nowadays circular autoloads do not work, but the user gets a NameError
that says some constant is undefined. That's puzzling, because he is
normally trying to autoload a constant he knows can be autoloaded.
With this check we can give a better error message.
The result of Generator with or without the @extras instance variable set contains the desired information. Rather than preserving state when initializing the original object, we can simply extract the keys from the resultant parameters.

Many named routes have keys that are required to successfully resolve. If a key is left off like this:
<%= link_to 'user', user_path %>
This will produce an error like this:
No route matches {:action=>"show", :controller=>"users"}
Since we know that the :id is missing, we can add extra debugging information to the error message.
No route matches {:action=>"show", :controller=>"users"} missing required keys: [:id]
This will help new and seasoned developers look closer at their parameters. I've also subclassed the routing error to be clear that this error is a result of attempting to generate a url and not because the user is trying to visit a bad url.
While this may sound trivial this error message is misleading and confuses most developers. The important part isn't what's in the options its's what's missing. Adding this information to the error message will make debugging much more obvious.
This is the sister pull request of https://github.com/rails/journey/pull/44 which will be required to get they missing keys into the correct error message.

loaded stores file names without the .rb extension, but search_for_file
returns file names with the extension.
The solution is hackish, but this file needs a revamp.
