Bug #3119: [Patch] "IOError (closed stream)" error with tempfile unlink then close usage http://redmine.ruby-lang.org/issues/show/3119 Author: Simon Nicholls Status: Open, Priority: Normal Category: lib ruby -v: ruby 1.9.2dev (2010-04-02 trunk 27189) [x86_64-darwin10] The Tempfile#unlink method clobbers Tempfile's @data variable, which _close needs in order to remove it's reference to the tmpfile correctly. This means that when the Remover finalizer runs, the (still valid) reference it has to @data is inspected, the tmpfile is found when it shouldn't be, and the tmpfile is closed again to cause the error. The patch simply removes the @data assignment from the following in unlink: @data = @tmpname = nil ---------------------------------------- http://redmine.ruby-lang.org
