parse_multipart bug fix for Content-Type and No Filename

Reported by Brendan Baldwin | March 24th, 2011 @ 05:32 PM

I posted this to github issues for rack project several months ago, but there have only been a couple replies from other users pushing for it. I assume that it is ignored because nobody on Rack team uses the github issues system. Reposting this here.


Rack 1.2 parse_multipart bug fix for Content-Type and No Filename

Ran into an issue upgrading to Rack 1.2 when users of our API using Apache HTTP Client were submitting multipart requests with a Content-Type but a Content-Disposition without "filename". This triggered a logical bug in the parse_multipart code that invoked a "rewind" call on a String object, expecting a Tempfile object instead.

Broke my commits into 2:

First one: 2c15ef595a509453bd94 has the spec and fixture that proves the bug.
Second one: 8f7fcf0fdd9fd99aa529 has the bug "fix".

I hesitate to say I grok everything going on in the parse_multipart code (whoaboy, thats some code) but this change appears innocuous enough, breaks no other specs and does what we expected it to on our end.
