Class Method Details

.capture_configures ⇒ Object

This is a method which will yield to a block and will capture all Vagrant.configure calls, returning an array of Procs.

Wrapping this around anytime you call code which loads configurations will force a mutex so that procs never get mixed up. This keeps the configuration loading part of Vagrant thread-safe.

def self.capture_configures
  CONFIGURE_MUTEX.synchronize do
    # Reset the last procs so that we start fresh
    @last_procs = []

    # Yield to allow the caller to do whatever loading needed
    yield

    # Return the last procs we've seen while still in the mutex,
    # knowing we're safe.
    return @last_procs
  end
end

.run(&block) ⇒ Object

This is the method which is called by all Vagrantfiles to configure Vagrant. This method expects a block which accepts a single argument representing an instance of the Top class.

Note that the block is not run immediately. Instead, it's proc is stored away for execution later.
