Protected Instance Methods

command() click to toggle source

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
39:           def command
40:             raise NotImplementedError, "`command' is not implemented by #{self.class.name}"
41:           end
mark() click to toggle source

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
45:           def mark
46:             "(echo #{revision} > #{configuration[:release_path]}/REVISION)"
47:           end
scm_run(command) click to toggle source

Runs the given command, filtering output back through the # filter of the SCM implementation.

    # File lib/capistrano/recipes/deploy/strategy/remote.rb, line 28
28:           def scm_run(command)
29:             run(command) do |ch,stream,text|
30:               ch[:state] ||= { :channel => ch }
31:               output = source.handle_data(ch[:state], stream, text)
32:               ch.send_data(output) if output
33:             end
34:           end
