Httplib2 - AttributeError: 'NoneType' object has no attribute 'makefile'

Question

How do I fix this?
PS: On googling, I found that this is some httplib2 bug but I didn't understand how to use the patches people have provided.

Traceback (most recent call last):

    func(code)
  File "alt_func.py", line 9, in func

Answer 1

This is a known issue: http://code.google.com/p/httplib2/issues/detail?id=96

There appear to be some dupes logged, or perhaps the same symptom arising from different circumstances:

• http://code.google.com/p/httplib2/issues/detail?id=101
• http://code.google.com/p/httplib2/issues/detail?id=102

Answer 2

You will also get this error if the server you are tying to connect to is not running or is on a different port. Quite a misleading error message, if you ask me.

Answer 3

You have created an HTTPConnection instance, but is it not connected to anything, so the sock still has the initial value of None

Can you post some code that exhibits this failure? Which patches are you using/trying to use
