[SRU] webob last stable version 1.1.1 response header bug

[peter.pang]

if u use webob last stable version 1.1.1 with swift and want to send a HEAD request to get an object info,

the response http header CONTENT-TYPE and CONTENT-LENGTH will be wrong,

it should return the real content type and real length of the object like: image/gif , 139520 (bytes)

but it just return text/html and all http header length

the real stable version i test is 1.0.8

thanks

The bug shows up in functional tests, this particular case triggers it:

    nosetests test.functional.tests:TestFile.testHead

We have traced it down to this change in WebOb made on Jun 30 2011, shortly after 1.0.8 was released:
https://github.com/Pylons/webob/commit/2e23e221ff85eac81623ff7a07b1a630ae263ec9
"make sure WSGIHTTPException return the same headers for HEAD and GET requests"

It appears that a contributing factor is that Swift uses exceptions even for successful results, such as webob.exc.HTTPOk. The erroneous content-type and content-length correspond to the textual representation of the HTTPOk "exception".
