Capistrano V3 failing on database.yml - ruby-on-rails

Question

I am using the latest version of Capistrano w/ my Rails 4 application. When running cap dpeloy. I get a lot of output including this failure:
DEBUG [04b6e226] Running /usr/bin/env [ -f /var/www/skateboxes/releases/20131022135522/config/database.yml ] on 162.243.33.179
DEBUG [04b6e226] Command: [ -f /var/www/skateboxes/releases/20131022135522/config/database.yml ]
DEBUG [04b6e226] Finished in 0.280 seconds with exit status 1 (failed).
How do I figure out what is going on here?
Update #1
I should say that I have gitignored config/database.yml (as was suggested by the capistrano docs). I then added the following to my config/deploy.rb
set :linked_files, %w{config/database.yml}
I then created a file on my VPS at /var/www/skateboxes/shared/config/database.yml.
Am I not understanding how linked_files works?
Update #2
It turns out that the file is actually being linked from shared/conf/database.yml to current/config/database.yml so now I'm confused as to why it's saying failed
Update #3
Here is the entire output of my deploy

Answer 1

That's not a failure, see https://github.com/leehambley/sshkit/pull/33.
It says failed because that is not a file, thus the test command ([ aka man (1) test) has exited with status 1.
The command in question is coming out of this code, reproduced below:
desc 'Symlink linked files'
task :linked_files do
next unless any? :linked_files
on roles :app do
execute :mkdir, '-pv', linked_file_dirs(release_path)
fetch(:linked_files).each do |file|
target = release_path.join(file)
source = shared_path.join(file)
unless test "[ -L #{target} ]"
if test "[ -f #{target} ]"
execute :rm, target
end
execute :ln, '-s', source, target
end
end
end
end
desc 'Check files to be linked exist in shared'
task :linked_files do
next unless any? :linked_files
on roles :app do |host|
linked_files(shared_path).each do |file|
unless test "[ -f #{file} ]"
error t(:linked_file_does_not_exist, file: file, host: host)
exit 1
end
end
end
end
The task name says it all, really, if your file is listed in the :linked_files variable, it must exist in shared_path, otherwise it will cause Capistrano to abort when the file does not exist.
You haven't yet said whether or not this is causing your deploy to fail, and since you've posted so little of the log, indicating nothing but normal behaviour, nobody can guess.
You appear to be posting logs from the Symlink linked files task, which is supposed to fail on config/database.yml if it doesn't exist, it has failed to find it, so it does not have to be deleted.
