Rails - Nov 2005 - EBADF error?

Hi all,

I get a (usually) reproducible error for only one of my controllers.  This
doesn''t happen for any of the other 10+ controllers.  I didn''t
see anything
weird about file permissions.  The "offending" line 142 is quite
innocuous
and triggers the error even when that portion of the controller is not even
being run.

   .
   .
   .
   141       while logfile.readline
   142         next unless /Average Redundancy Per Shell/
   143         break
   144       end
   .
   .
   .

The error looks like this in the logs/development.log file.  I''ve
edited
it slightly to allow for posting.

  Processing Base#index (for 127.0.0.1 at Thu Nov 03 15:43:02 Eastern...

I''m running Rails 0.13.1 + Webrick 1.3.1 in development mode on a WinXP
box.

Thanks in advance for your insight.

Anyone?  Anyone?  Bueller?

Seriously, I can''t believe that I''m the only person who has
seen this error.

Have you tried rewriting these lines of code without using ruby
"shortcuts"?

  while str = logfile.readline
    next unless str =~ /Average Redundancy Per Shell/
    break
  end

You''re the man, Saltman!  I made your suggested change and it seems to
be
working.  Thanks a bunch.  I wonder if this is a ruby on windows-only issue?
