Hi!

Thanks for your reply!

Unfortunately, Net::FTP#getbinaryfile does not accept nil, as far as I 
understand the source, it passes the parameter to open, and dies with

H:/ruby/ruby_install/ruby/lib/ruby/1.8/open-uri.rb:87:in 
`open_uri_original_open': cannot convert nil into String (TypeError)

When I change

ftp.getbinaryfile(self.path, '/dev/null', Net::FTP::DEFAULT_BLOCKSIZE) 
{|str|

to

ftp.getbinaryfile(self.path) {|str|

in open-uri.rb, it only falls back to  Net::FTP#getbinaryfile's default 
value, which simply is the basename of the remote file, so that I end up 
with the file on my hard drive. (This sounds strange if you don't know 
the context, but this gets called from open("ftp://") with a block, so I 
want to handle the data myself without temporary storage on disk) .

I'm stuck. Would this not be a problem if I were using the cygwin build, 
because there might exist some fake /dev/null?

Henrik
