Subject: Not cleaning up tempfiles for multipart?
Date: Fri, 5 Mar 2010 08:40:11 -0600	[thread overview]
Message-ID: <f04d2211003050640m328f5551l225e36ab5a8e2724@mail.gmail.com> (raw)

I'm investigating some reported tempfle bugs in JRuby, and it seems
like Rack may not be cleaning up tempfiles it uses.

The creation of the tempfile happens at utils.rb line 486:

      if content_type || filename
>>    body = Tempfile.new("RackMultipart")
        body.binmode  if body.respond_to?(:binmode)
      end

The body is then written to (with the content of the request body),
rewound, put into the "data" structure, passed to normalize_params
(which inserts the "data" into the params hash), and that's it. The
params are then presumably used for the request, and nobody ever
explicitly cleans up the tempfile.

Am I looking in the wrong place?

If I'm correct, this is a bug. Tempfiles should not be relied upon to
clean themselves up in response to GC, since you don't know when GC
will fire...
