Public Class Methods

in_fork(&block) click to toggle source

Executes block in a (detached) fork, saving the `pid` for later termination. @note add `ensure MachineLearningWorkbench::Tools.kill_forks` to the block

where `in_fork` is called (see `#kill_forks`).
# File lib/machine_learning_workbench/tools/execution.rb, line 10
def self.in_fork &block
  raise ArgumentError "Need block to be executed in fork" unless block
  pid = fork(&block)
  Process.detach pid
  $fork_pids << pid
end
kill_forks() click to toggle source

Kills processes spawned by `#in_fork`. Call this in an `ensure` block after using `in_fork`.

def self.kill_forks
  $fork_pids&.each { |pid| Process.kill('KILL', pid) rescue Errno::ESRCH }
