Some clarification on Capistrano 2 's deploy.rb

[niristotle okram]

Versions:

• Ruby   2.1.1
• Capistrano  2

Platform:

• Working on....
• Deploying to... RHEL 6.6

Files:

• Capfile
• deploy.rb

require 'capistrano/chef'

require "capistrano/ext/multistage"

set :application, "test"

set :repository, 'ssh:/...................'

set :user, 'deployer'

#the below line is to avoid git clone on every deployment

set :deploy_via, :remote_cache

set :deploy_to, '/opt/mount1/test'

set :scm, :git

#line to avoid saving the files declared

set :copy_exclude, [".git", ".gitignore"]

set :scm_verbose, true

ssh_options[:paranoid] = false

default_run_options[:pty] = true

# set :scm, :git # You can set :scm explicitly or Capistrano will make an intelligent guess based on known version control directory names

# Or: `accurev`, `bzr`, `cvs`, `darcs`, `git`, `mercurial`, `perforce`, `subversion` or `none`

#before "deploy", "deploy:stop_app"

#after "deploy", "deploy:start_app"

after "deploy", "deploy:restart_app"

namespace :deploy do

  task :update_code, :roles => :web, :except => { :no_release => true } do

    on_rollback { puts "some message?" }

    strategy.deploy!

    finalize_update

  end

  task :stop_app, :roles => :web do

    run "sudo /etc/init.d/test stop", :shell => :bash

  end

  task :start_app, :roles => :web do

    run "sudo /etc/init.d/test start", :shell => :bash

  end

  task :restart_app, :roles => :web do

    run "sudo /etc/init.d/test restart", :shell => :bash

  end

end

------------------------------------

So, in the above 'deploy.rb', there is this block below. 

namespace :deploy do

  task :update_code, :roles => :web, :except => { :no_release => true } do

    on_rollback { puts "some message?" }

    strategy.deploy!

    finalize_update

  end

Question:

1. where is this task 'update_code' defined? is this the one that pulls down the code to the 'deploy_to' location and performs the symlinks etc?

2. this else condition for the update_code task 

:except => { :no_release => true } do

    on_rollback { puts "some message?" }

    strategy.deploy!

    finalize_update

what do they mean? where can i find the meaning of ' strategy.deploy!' and ' finalize_update'

Thanks

I'm sorry I can't be more helpful, but most of it you will find documented in source code here - https://github.com/capistrano/capistrano/tree/legacy-v2 specifically under that tag. The v2 code is now *very* old.
