=begin
I cannot reproduce above error. However, Bug #4168 and #5350 seem not
solved.
I got NoMethodError by the following script. WeakRef object has
reference to different object from originally associated.
% cat test_weakref.rb
require "weakref"
class Foo
def foo; end
end
a = []
1000.times do
a << WeakRef.new(Foo.new)
end
a.each do |x|
begin
x.foo
rescue WeakRef::RefError
p :referr
end
end
% ruby -v test_weakref.rb
ruby 2.0.0dev (2012-11-08 trunk 37558) [i686-linux]

Hello,
Over the past few days I've seen on and off failures on RubyInstaller CI
related to (({test_autoclose_true_closed_by_finalizer})):
http://ci.rubyinstaller.org/job/ruby-trunk-x86-tes...
1) Error:
test_autoclose_true_closed_by_finalizer(TestIO):
NoMethodError: undefined method `close' for 2012-11-07 04:43:41
-0300:WeakRef
C:/Users/Worker/Jenkins/workspace/ruby-trunk-x86-build/test/ruby/test_io.rb:1611:in
`test_autoclose_true_closed_by_finalizer'
This seems to happen when the system is under heavy load (because is
running other jobs in parallel).
This might be a hint of something not working properly under heavy load,
perhaps the GC in effect.
I was unable to produce the same failure on x64-mingw32, and haven't
tried yet OSX or Linux.
Any ideas?

Issue #7304 has been updated by h.shirosaki (Hiroshi Shirosaki). File 0001-Fix-WeakRef-finalize.patch added After some investigation, I found WeakRef finalize code appears wrong. When finalize, object references were not removed from weakmap hash properly. I attached a patch. I tested it with ruby 2.0.0dev (2012-11-09 trunk 37558) [i686-linux]. ---------------------------------------- Bug #7304: Random test failures around test_autoclose_true_closed_by_finalizer https://bugs.ruby-lang.org/issues/7304#change-32701 Author: luislavena (Luis Lavena) Status: Assigned Priority: Normal Assignee: ko1 (Koichi Sasada) Category: test Target version: 2.0.0 ruby -v: ruby 2.0.0dev (2012-11-07 trunk 37538) [i386-mingw32] =begin Hello, Over the past few days I've seen on and off failures on RubyInstaller CI related to (({test_autoclose_true_closed_by_finalizer})): http://ci.rubyinstaller.org/job/ruby-trunk-x86-tes... 1) Error: test_autoclose_true_closed_by_finalizer(TestIO): NoMethodError: undefined method `close' for 2012-11-07 04:43:41 -0300:WeakRef C:/Users/Worker/Jenkins/workspace/ruby-trunk-x86-build/test/ruby/test_io.rb:1611:in `test_autoclose_true_closed_by_finalizer' This seems to happen when the system is under heavy load (because is running other jobs in parallel).

Issue #7304 has been updated by h.shirosaki (Hiroshi Shirosaki). Status changed from Closed to Assigned % Done changed from 100 to 0 This fix causes segv, which was pointed out at r37831. Thank you, naruse-san. I found rb_ary_delete(ary, obj) is not usable when doing WeakRef finalize because rb_ary_delete() calls rb_equal() against GC'ed WeakRef object. Instead just comparing VALUE by '==' seems good for this case. I'll fix later. ---------------------------------------- Bug #7304: Random test failures around test_autoclose_true_closed_by_finalizer https://bugs.ruby-lang.org/issues/7304#change-33813 Author: luislavena (Luis Lavena) Status: Assigned Priority: High Assignee: h.shirosaki (Hiroshi Shirosaki) Category: core Target version: 2.0.0 ruby -v: ruby 2.0.0dev (2012-11-07 trunk 37538) [i386-mingw32] =begin Hello, Over the past few days I've seen on and off failures on RubyInstaller CI related to (({test_autoclose_true_closed_by_finalizer})): http://ci.rubyinstaller.org/job/ruby-trunk-x86-tes... 1) Error: test_autoclose_true_closed_by_finalizer(TestIO): NoMethodError: undefined method `close' for 2012-11-07 04:43:41 -0300:WeakRef C:/Users/Worker/Jenkins/workspace/ruby-trunk-x86-build/test/ruby/test_io.rb:1611:in `test_autoclose_true_closed_by_finalizer' This seems to happen when the system is under heavy load (because is running other jobs in parallel).
