Feature #8961
Updated by nobu (Nobuyoshi Nakada) almost 11 years ago
=begin I propose a Synchronizable mixin to easily wrap methods in a mutex which works together with Ruby 2.1's method name symbols returned from '(({def}))'. 'def'. The Mixin adds a new '(({synchronized}))' 'synchronized' class method which would alias the referenced method and redefines the original method wrapped in a '(({synchronize 'synchronize do .. end}))' end' block. This is probably somewhat related and an alternative to #8556. --- -- Proof of concept (I've used Monitor here so potential users won't have to worry about reentrancy): require 'monitor' module Synchronizable module ClassMethods def synchronized(method) aliased = :"#{method}_without_synchronization" alias_method aliased, method define_method method do |*args, &block| monitor.synchronize do __send__(aliased, *args, &block) end end end end end def monitor @monitor ||= Monitor.new end def self.included(base) base.extend(ClassMethods) end end end class Foo include Synchronizable synchronized def bar # ... end end =end end
