files produced by asset:precompile don't match urls generated by stylesheet_link_tag (missing digest) in minimal rails 4 site -

i'm using ruby 2.0.0-p247 , rails 4.0.0

if make minimal rails 4 site this:

rails new minimal cd minimal rails generate controller home index tee config/routes.rb <<eof minimal::application.routes.draw   root 'home#index' end eof 

then precompile assets with

rake assets:precompile 

it generates assets like:

i, [2013-09-04t17:05:36.992951 #3549]  info -- : writing /workingdir/minimal/public/assets/application-723d1be6cc741a3aabb1cec24276d681.js i, [2013-09-04t17:05:37.052303 #3549]  info -- : writing /workingdir/minimal/public/assets/application-f1a14051f17824976271b9c0460232f0.css 

but if start server in production mode, with

rails_env=production rails s 

the generated urls in html don't point @ precompiled files:

<link data-turbolinks-track="true" href="/stylesheets/application.css" media="all" rel="stylesheet" /> <script data-turbolinks-track="true" src="/javascripts/application.js"></script> 

i expect, rather:

<link data-turbolinks-track="true" href="assets/application-f1a14051f17824976271b9c0460232f0.css" media="all" rel="stylesheet" /> <script data-turbolinks-track="true" src="/assets/application-723d1be6cc741a3aabb1cec24276d681.js"></script> 

the default config/environments/production.rb settings use digests:

config.assets.digest = true 

but seems selectively ignored?

am missing something?

update:

i tested in rails 4.2.3 , appears fixed, need hand few more environment variables rails s command start in production mode:

secret_key_base=$(rake secret) rails_serve_static_files=true rails_env=production rails s 

while writing question came across blog post suggests bug.

http://railsblog.kieser.net/2013/08/rails4-phusion-passenger-asset-pipeline.html

of various suggestions, setting compilation fallback true...

config.assets.compile = true 

seems sufficient kick rails in generating appropriately digested urls:

<link data-turbolinks-track="true" href="/assets/application-f1a14051f17824976271b9c0460232f0.css" media="all" rel="stylesheet" /> <script data-turbolinks-track="true" src="/assets/application-723d1be6cc741a3aabb1cec24276d681.js"></script> 

the other suggestion, explicitly setting rails_env , rails_groups seemed produce different digest strings on precompiled files, seem match generated html regardless.
