"socket.error: [Errno 32] Broken pipe" when uploading an attachment using auth

[GoogleCodeExporter]

This is occurring using:

CouchDB-Python SVN r138
CouchDB SVN r756688

(both latest at time of writing)

I can only seem to reproduce this when running it on the same machine as
the CouchDB instance.  See attached for a minimal reproducible test case.

After digging deeper, it seems there may be a bug in Python's httplib or in 
httplib2,
which only occurs if the server closes the socket before the client has had a 
chance
to send the request body.  This is the case for CouchDB - once it has read the
request headers it immediately attempts auth, and it

I think this is acceptable (and HTTP-compliant) behaviour.  It just means that 
even
if the httplib/httplib2 client library gets a broken pipe error when writing the
request body, it should check for a response first before propagating the error.

I am working on finding a workaround or a patch for httplib/httplib2, watch 
this space.

Just filed a bug in the Python bug tracker for httplib: 
http://bugs.python.org/issue5542

I also have a patch for httplib2.

Jason, can I correctly conclude that we probably shouldn't do anything to fix 
this in
CouchDB-python?
