An abstract superclass, which forms the base for all deployment strategies which work by grabbing the code from the repository directly from remote host. This includes deploying by checkout (the default), and deploying by export.
# File lib/capistrano/recipes/deploy/strategy/remote.rb, line 18 def check! super.check do |d| d.remote.command(source.command) end end
Executes the SCM command for this strategy and writes the REVISION mark file to each host.
# File lib/capistrano/recipes/deploy/strategy/remote.rb, line 14 def deploy! scm_run "#{command} && #{mark}" end
An abstract method which must be overridden in subclasses, to return the actual SCM command(s) which must be executed on each target host in order to perform the deployment.
# File lib/capistrano/recipes/deploy/strategy/remote.rb, line 39 def command raise NotImplementedError, "`command' is not implemented by #{self.class.name}" end
Returns the command which will write the identifier of the revision being deployed to the REVISION file on each host.
# File lib/capistrano/recipes/deploy/strategy/remote.rb, line 45 def mark "(echo #{revision} > #{configuration[:release_path]}/REVISION)" end
Runs the given command, filtering output back through the handle_data filter of the SCM implementation.
# File lib/capistrano/recipes/deploy/strategy/remote.rb, line 28 def scm_run(command) run(command) do |ch,stream,text| ch[:state] ||= { :channel => ch } output = source.handle_data(ch[:state], stream, text) ch.send_data(output) if output end end
