Subject: [ruby-core:44181] [ruby-trunk - Bug #6269][Open] Process.spawn does not work with Tempfile


Issue #6269 has been reported by matled (Matthias Lederhofer).

----------------------------------------
Bug #6269: Process.spawn does not work with Tempfile
https://bugs.ruby-lang.org/issues/6269

Author: matled (Matthias Lederhofer)
Status: Open
Priority: Normal
Assignee: 
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]
