# This defines a deployment "recipe" that you can feed to capistrano
#  http://manuals.rubyonrails.com/read/book/17). It allows you to automate
# (among other things) the deployment of your application.

# =============================================================================
# REQUIRED VARIABLES
# =============================================================================
# You must always specify the application and repository for every recipe. The
# repository must be the URL of the repository you want this recipe to
# correspond to. The deploy_to path must be the path on each machine that will
# form the root of the application path.

set :application, "uegapp"
set :domain, "owen.hostingrails.com"
set :user, "unitede"

set :repository,  "svn+ssh://#{user}@#{domain}/home/#{user}/svn/#{application}/trunk"
set :use_sudo, false
set :deploy_to, "/home/#{user}/apps/#{application}"
set :deploy_via, :checkout
set :chmod755, "app config db lib public vendor script script/* public/disp*"
set :mongrel_port, "4104"

# =============================================================================
# ROLES
# =============================================================================
# You can define any number of roles, each of which contains any number of
# machines. Roles might include such things as :web, or :app, or :db, defining
# what the purpose of each machine is. You can also specify options that can
# be used to single out a specific subset of boxes in a particular role, like
# :primary => true.

role :web, domain
role :app, domain
role :db,  domain, :primary => true

# =============================================================================
# OPTIONAL VARIABLES
# =============================================================================
# set :deploy_to, "/path/to/app" # defaults to "/u/apps/#{application}"
# set :user, "flippy"            # defaults to the currently logged in user
# set :scm, :darcs               # defaults to :subversion
# set :svn, "/path/to/svn"       # defaults to searching the PATH
# set :darcs, "/path/to/darcs"   # defaults to searching the PATH
# set :cvs, "/path/to/cvs"       # defaults to searching the PATH
# set :gateway, "gate.host.com"  # default to no gateway

# =============================================================================
# SSH OPTIONS
# =============================================================================
# ssh_options[:keys] = %w(/path/to/my/key /path/to/another/key)
# ssh_options[:port] = 25

# =============================================================================
# TASKS
# =============================================================================
# Define tasks that run on all (or only some) of the machines. You can specify
# a role (or set of roles) that each task should be executed on. You can also
# narrow the set of servers to a subset of a role by specifying options, which
# must match the options given for the servers to select (like :primary => true)

desc <<DESC
An imaginary backup task. (Execute the 'show_tasks' task to display all
available tasks.)

task :backup, :roles => :db, :only => { :primary => true } do
  # the on_rollback handler is only executed if this task is executed within
  # a transaction (see below), AND it or a subsequent task fails.
  on_rollback { delete "/tmp/dump.sql" }

  run "mysqldump -u theuser -p thedatabase > /tmp/dump.sql" do |ch, stream, out|
    ch.send_data "thepassword\n" if out =~ /^Enter password:/
  end
end

# Tasks may take advantage of several different helper methods to interact
# with the remote server(s). These are:
#
# * run(command, options={}, &block): execute the given command on all servers
#   associated with the current task, in parallel. The block, if given, should
#   accept three parameters: the communication channel, a symbol identifying the
#   type of stream (:err or :out), and the data. The block is invoked for all
#   output from the command, allowing you to inspect output and act
#   accordingly.
# * sudo(command, options={}, &block): same as run, but it executes the command
#   via sudo.
# * delete(path, options={}): deletes the given file or directory from all
#   associated servers. If :recursive => true is given in the options, the
#   delete uses "rm -rf" instead of "rm -f".
# * put(buffer, path, options={}): creates or overwrites a file at "path" on
#   all associated servers, populating it with the contents of "buffer". You
#   can specify :mode as an integer value, which will be used to set the mode
#   on the file.
# * render(template, options={}) or render(options={}): renders the given
#   template and returns a string. Alternatively, if the :template key is given,
#   it will be treated as the contents of the template to render. Any other keys
#   are treated as local variables, which are made available to the (ERb)
#   template.
