Subject: Re: Strange rubyzip behaviour (Errno::EFBIG)

I have never experienced the Errno::EFBIG exception myself. If anyone
else on this list has tried rubyzip and seen this problem I'd be
interested in hearing about it.

Travis, could you try something like this:

require 'zip/zip'

is = File.open("rubycode.zip", "rb")
is.seek(5, IO::SEEK_SET)
is.read

Does that cause the problem? If it does, try without requiring
'zip/zip'.

Rubyzip doesn't do anything too weird with the files, all it does is
opening the archive file in "rb"-mode and seek-around and read a bit,
which is what the code fragment above is intended to mimic.

I have run the test suite succesfully myself on Windows XP/ruby-1.8.0
(pragprog build) and on RedHat 9.0 Linux/ruby-1.8.1 before making the
release.

Cheers,

Thomas
