Feature #10718: IO#close should not raise IOError on closed IO objects. - Ruby master - Ruby Issue Tracking System

I'd like to change IO#close. It should not raise IOError on closed IO objects. We sometimes invoke IO#close only when the IO object is not closed as: f.close if !f.closed? If this issue is accepted, we can write it simply as follows. f.close Simple grep finds many examples. Following examples are just a little excerpt. lib/webrick/server.rb: sock.close unless sock.closed? lib/pstore.rb: file.close
