I know. -- Yusuke Endoh ---------------------------------------- Bug #6269: Process.spawn does not work with Tempfile https://bugs.ruby-lang.org/issues/6269#change-25785 Author: matled (Matthias Lederhofer) Status: Assigned Priority: Normal Assignee: nobu (Nobuyoshi Nakada) Category: Target version: ruby -v: ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux] The following code fails with an exception: require 'tempfile' tmp = Tempfile.new(File.basename($0)) Process.spawn("date", :out => tmp) Exception: in `spawn': wrong exec redirect action (ArgumentError) I would expect that Process.spawn accepts a Tempfile object just as a File or IO object. check_exec_redirect fails to detect that a Tempfile object may be used as an IO. I guess check_exec_redirect_fd should be called even if the object is not of type T_FILE. I've tried the following ruby versions: ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux] ruby 2.0.0dev (2012-04-07 trunk 35250) [x86_64-linux] -- http://bugs.ruby-lang.org/
