asset_host (as a proc) generates different digest for the same content

[dnagir]

Repro (rail 4.1x, Ruby 2.1):

GIven this in config/applicaiton.rb

    config.assets.enabled = true
    config.assets.initialize_on_precompile = false

    config.assets.precompile = ['application.js']
    config.action_controller.asset_host = proc { |source, request| 'http://example.com' }

(note the proc is used that always returns the same value)

And the app/assets/javascripts/application.js file with the simple content:

alert('hi')

When I run the precompile task multiple time, I'm getting different file names (digest) generated every time I run the precompilation:

$ rm -rf public/assets/ && RAILS_ENV=production RAILS_GROUP=assets bundle exec rake assets:precompile
I, [2014-06-30T17:24:55.598915 #52443]  INFO -- : Writing /Users/dnagir/proj/pc/abc/public/assets/application-7eafc8bc5bc0cdf0d1960b64bdff6a15.js

$ rm -rf public/assets/ && RAILS_ENV=production RAILS_GROUP=assets b rake assets:precompile
I, [2014-06-30T17:24:58.784216 #52513]  INFO -- : Writing /Users/dnagir/proj/pc/abc/public/assets/application-124c96284aeddcd0a85f2f370e021ac2.js

Bothe generated files have exactly the same content:

alert('hi')
;

The minimal Gemfile:

source 'http://rubygems.org'

gem 'rails', '~> 4.1.2'

gem 'pg'

This sounds like #138 -- @dnagir can you confirm?

[rafaelfranca]

Yes, seem so. I guess I need to release a new version. I'll do today.

[dnagir]

Yes, looks like it. Thanks.

I'll comment there.
