Subject: [ruby-core:50037] [ruby-trunk - Bug #7304][Assigned] Random test failures around test_autoclose_true_closed_by_finalizer


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.

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-test-all/265/console

 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?
