require 'puppet'
# A module for building AtFork handlers. These handlers are objects providing
# pre/post fork callbacks modeled after those registered by the `pthread_atfork`
# function.
# Currently there are two AtFork handler implementations:
# - a noop implementation used on all platforms except Solaris (and possibly
# even there as a fallback)
# - a Solaris implementation which ensures the forked process runs in a different
# contract than the parent process. This is necessary for agent runs started by
# the puppet agent service to be able to restart that service without being
# killed in the process as a consequence of running in the same contract as the
# service.
