Subject: [ruby-core:23252] [Bug #1392] Object#extend leaks memory on Ruby 1.9.1
Date: Sun, 19 Apr 2009 07:18:18 +0900 [thread overview]
Message-ID: <49ea51a1deec_323f5bb5b52104e@redmine.ruby-lang.org> (raw)
Bug #1392: Object#extend leaks memory on Ruby 1.9.1
http://redmine.ruby-lang.org/issues/show/1392
Author: Muhammad Ali
Status: Open, Priority: Normal
Category: core, Target version: 1.9.1
ruby -v: ruby 1.9.1p0 (2009-01-30 revision 21907) [i686-linux]
A few bytes are leaked every time Object#extend is called, here is a sample 1.9.1 script
# This code is Ruby 1.9.x and above only
@extend = ARGV[0]
module BetterHash
def blabla
end
end
unless @extend
class Hash
include BetterHash
end
end
t = Time.now
1_000_000.times do
s = {}
s.extend BetterHash if @extend
end
after = Time.now - t
puts "done with #{GC.count} gc runs after #{after} seconds"
sleep # so that it doesn't exit before we check the memory
