Bug 984991

+++ This bug was initially created as a clone of Bug #970658 +++

Description of problem:
It appears that the ruby 1.9 cartridge has a "bundle exec rake assets:precompile" in it by default somewhere.

Unfortunately, not all ruby/rack applications are rails, and, therefore, there may not be any default rake actions, let alone "assets:precompile".

Steps to Reproduce:
1. Create a ruby 1.9 application
2. Push code into it that has no rails/rake

Actual results:
remote: Precompiling with 'bundle exec rake assets:precompile'
remote: rake aborted!
remote: Don't know how to build task 'assets:precompile'
remote: 
remote: (See full trace by running task with --trace)

Expected results:
Should somehow figure out if we are using Rails or not and not try to do the precompile if the rake action doesn't exist.

Please verify this is not an issue with the V2 cartridges.

At the moment, on v2, 'set +e' and 'set -e' wrap the call to 'rake assets:precompile', so that the failure from this rake task is not fatal. The error message is annoying, but it should not stop the deployment.

As for v1, STDERR is swallowed at the moment, so the user should not see this error message. (See https://bugzilla.redhat.com/show_bug.cgi?id=862919, which was fixed many months ago by https://github.com/openshift/origin-server/commit/e7dba7f.) I am not sure how the error message is showing up now.

Eric, can you check how recent your origin server is?

--- Additional comment from Hiro Asari on 2013-06-05 15:34:36 EDT ---

Test case (ensure the server is using v1 cartridges):

rhc app create rack ruby-1.9 -l $RHC_USERNAME --server $RHC_SERVER
cd rack
touch Rakefile
curl -O https://gist.github.com/BanzaiMan/71d71d884937848d3184/raw/4824c4815eb785de278e356b9b8a22a347520a2f/Gemfile
bundle install
git add Rakefile Gemfile*
git commit -m 'empty Rakefile and Gemfile with "rake"'
git push

Eric,

I confirmed the error message bubbling up to the git output in the latest server, so you don't have to do anything further. I apologize for the confusion.

Bug 970658

Run 'rake assets:precompile' only if that Rake task is available.

--- Additional comment from Hiro Asari on 2013-06-06 09:15:03 EDT ---

It should be tested on v1 (1.8 and 1.9) and v2 cartridges.

Tested on devenv_3336,

For both ruby1.9 and ruby1.8

With steps in comment#4, issue fixed.
