New issue 14 by daniel...@gmail.com: AttributeError: BeatBoxXmlGenerator
instance has no attribute '_out'
http://code.google.com/p/salesforce-beatbox/issues/detail?id=14

What steps will reproduce the problem?
1. Deploy Ubuntu 13.04.
2. Deploy and import the beatbox library.
3. Attempt to login.
4. Observe error.

What is the expected output?
I expect to see a the login method for the client return a valid dictionary.

What do you see instead?
An error. Something similar to the following...

File "./script", line 52, in <module>
svc.login('us...@salesforce.com', 'password123' + 'tokentokentoken')
File "/any/given/path/beatbox/python_client.py", line 73, in login
res = BaseClient.login(self, username, passwd)
File "/any/given/path/beatbox/_beatbox.py", line 60, in login
lr = LoginRequest(self.serverUrl, username, password).post()
File "/any/given/path/beatbox/_beatbox.py", line 309, in post
conn.request("POST", path, self.makeEnvelope(), headers)
File "/any/given/path/beatbox/_beatbox.py", line 266, in makeEnvelope
s = SoapWriter()
File "/any/given/path/beatbox/_beatbox.py", line 243, in __init__
self.startElement(_envNs, "Envelope")
File "/any/given/path/beatbox/_beatbox.py", line 177, in startElement
self.xg.startElementNS((namespace, name), name, attrs)
File "/any/given/path/beatbox/_beatbox.py", line 146, in startElementNS
self._out.write('<' + self.makeName(name))

This patch allows it to work. Had to import hashlib for the unicode bits...

Why is hashlib necessary here?

This problem just cropped up for us. Any idea what caused it to start
appearing some new version of python?

hashlib is not necessary. Otherwise - patch fixes it for me.

Any chance to get it merged?

_out was an internal variable of XMLGenerator, and the internal
implementation changed. A reminder that _* variables should be regarded as
implementation-specific.

A slightly simpler and more robust fix:

Line 137:

+ self._out = destination
