Cannot figure out multistage environment, unicorn_rails and -E flag

[danman01]

I've been using this gem for a while (awesome - thanks!) and just took the dive to try deploying an actual staging environment to my staging server, and I ran into issues. Unicorn starts with the command unicorn_rails and -E production despite all the settings being correct afaik.

This may be something unique to my machine, so asking on stack overflow as well: http://stackoverflow.com/questions/18902002/capistrano-uniocorn-gem-multistage-environment-defaulting-to-unicorn-rails-and

I noticed in deploy.rb that my unicorn_bin variable was set as unicorn_rails. I took out this setting in my deploy.rb. However unicorn:duplicate still executes the unicorn_rails command, when the default should be unicorn.

My vars are all set to staging in the deploy/staging.rb, as outlined in the multistage setup wiki document, but I noticed -E is still getting set to production.

Relevent info:

Here's my output from my unicorn.log file after a deploy:

executing ["/var/www/apps/myapp/shared/bundle/ruby/2.0.0/bin/unicorn_rails", "-c",
"/var/www/apps/myapp/current/config/unicorn.rb", "-E", "production", "-D",
{12=>#<Kgio::UNIXServer:/tmp/myapp.socket>, 13=>#<Kgio::TCPServer:fd 13>}] (in /var/www/apps/myapp/current)

Here's the output from cap unicorn:show_vars (defaults to staging)

# Environments
rails_env "staging"
unicorn_env "staging"
unicorn_rack_env "staging"

# Execution
unicorn_user nil
unicorn_bundle "/usr/local/rvm/gems/ruby-2.0.0-p247@global/bin/bundle"
unicorn_bin "unicorn"
unicorn_options "" unicorn_restart_sleep_time 2`

# Relative paths
app_subdir ""
unicorn_config_rel_path "config"
unicorn_config_filename "unicorn.rb"
unicorn_config_rel_file_path "config/unicorn.rb"
unicorn_config_stage_rel_file_path "config/unicorn/staging.rb"

# Absolute paths
app_path "/var/www/apps/myapp/current"
unicorn_pid "/var/www/apps/myapp/shared/pids/unicorn.myapp.pid"
bundle_gemfile "/var/www/apps/myapp/current/Gemfile"
unicorn_config_path "/var/www/apps/myapp/current/config"
unicorn_config_file_path "/var/www/apps/myapp/current/config/unicorn.rb"
unicorn_config_stage_file_path
-> "/var/www/apps/myapp/current/config/unicorn/staging.rb"

And another curiousity, the unicorn_rails -E flag should reference the rails environment, whereas the unicorn -E should reference the rack env -- the rack env should only get the values developement and deployment, but it gets set to production, which is a bit strange.

Any insight into this would be much appreciated. On my staging server, I've also set the RAILS_ENV to staging. I've set up the things for rails for another environment, like adding staging.rb in my environments folder, adding a staging section to database.yml, etc.

important lines in lib/capistrano-unicorn/config.rb talking about unicorn_rack_env:

_cset(:unicorn_env) { fetch(:rails_env, 'production' ) } _cset(:unicorn_rack_env) do fetch(:rails_env) == 'development' ? 'development' : 'deployment' end

Thanks in advance.
