Method: Puppet::Application.controlled_run

Defined in:
lib/puppet/application.rb

.controlled_run(&block) ⇒ Object

Only executes the given block if the run status of Puppet::Application is clear (no restarts, stops, etc. requested). Upon block execution, checks the run status again; if a restart has been requested during the block’s execution, then controlled_run will send a new HUP signal to the current process. Thus, long-running background processes can potentially finish their work before a restart.
