Rails - Jan 2006 - Apache2 and popen

I''m running Apache2 on windows and I have a controller that issues a
popen.

class FileController < ApplicationController
  def index
   f = IO.popen("dir")
   @files = f.readlines
  end
end

This works using webbrick but on Apache produces...

----------
 Errno::ENOENT in File#index

No such file or directory - dir

RAILS_ROOT: C:/www/teensymud/public/../config/..
Application Trace | Framework Trace | Full Trace

#{RAILS_ROOT}/app/controllers/repository_controller.rb:3:in `popen''
#{RAILS_ROOT}/app/controllers/repository_controller.rb:3:in `index''

----------

Is this a known Apache problem, misconfiguration problem, or Ruby or Rails 
issue?
I''m running 2.0.54.

Thanks,

Jon Lambert

OT: but for this directory listing i suggest you use Dir module

a=Dir[''*'']
>>["rubygems-0.8.11.zip", "ruby182-15.exe",
"ruby-oci8-0.1.13.tar.]

Yes, I''m actually running subversion commands from rscm.   I just
wanted to
post the smallest and most easily produced code example that eliminated 
other possible problems like ACL and PATH being wrong.  That''s why I
used
`dir`.

Reproducted here (XP, Apache 2.0.55, FastCGI)

Perhaps passing "c:\win\cmd.exe /c dir" ?

Here i''m getting #<IO:0x379a0d0>

with  @f = IO.popen("c:/windows/system32/cmd.exe /c dir")

and <%=debug @f %>

But I''saw a command windows appearing, not really clean..

Hmm.  I am using FastCGI as well.  So I switched to CGI and it works.
Looks like FastCGI and popen aren''t playing well together.
