Issue #7304 has been reported by luislavena (Luis Lavena). ---------------------------------------- Bug #7304: Random test failures around test_autoclose_true_closed_by_finalizer https://bugs.ruby-lang.org/issues/7304 Author: luislavena (Luis Lavena) Status: Open Priority: Normal Assignee: ko1 (Koichi Sasada) Category: test Target version: 2.0.0 ruby -v: 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-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? =end -- http://bugs.ruby-lang.org/
