# Timeout long-running blocks # # == Synopsis # # require 'timeout' # status = Timeout::timeout(5) { # # Something that should be interrupted if it takes more than 5 seconds... # } # # == Description # # Timeout provides a way to auto-terminate a potentially long-running # operation if it hasn't finished in a fixed amount of time. # # Previous versions didn't use a module for namespacing, however # #timeout is provided for backwards compatibility. You # should prefer Timeout#timeout instead. # # == Copyright # # Copyright:: (C) 2000 Network Applied Communication Laboratory, Inc. # Copyright:: (C) 2000 Information-technology Promotion Agency, Japan module Timeout # Raised by Timeout#timeout when the block times out. class Error < RuntimeError end class ExitException < ::Exception # :nodoc: end # :stopdoc: THIS_FILE = /\A#{Regexp.quote(__FILE__)}:/o CALLER_OFFSET = ((c = caller[0]) && THIS_FILE =~ c) ? 1 : 0 # :startdoc: # Perform an operation in a block, raising an error if it takes longer than # +sec+ seconds to complete. # # +sec+:: Number of seconds to wait for the block to terminate. Any number # may be used, including Floats to specify fractional seconds.
