Overview

Rake::Multilogs groups multitask output by task, displaying it when all tasks have completed, rather than the default behavior of displaying output immediately (which means that output from different tasks becomes confusingly interleaved).

This requires Process.fork, so is not supported on JRuby or Windows.

Class Method Details

.after_fork(&block) ⇒ void

This method returns an undefined value.

Register a block to be called before executing a task. This is called from the child processes after forking, and from the parent process after the prerequisites have completed and the child processes have exited. In each case it will receive the task that is about to execute as a parameter.

Examples:

Handling database connections with Active Record

Rake::Multilogs.after_fork do
  ActiveRecord::Base.establish_connection
end

Parameters:

  • block (#to_proc) —

    the block to call (must accept zero or one parameters)

.before_fork(&block) ⇒ void

Examples:

Handling database connections with Active Record

Rake::Multilogs.before_fork do
  ActiveRecord::Base.connection.disconnect!
end

Parameters:

  • block (#to_proc) —
