open() renders "TypeError: setcontents() got an unexpected keyword argument 'errors'" exception
Using the open() method, I kept getting three variations of the same exception:

TypeError: setcontents() got an unexpected keyword argument 'errors'
I got exceptions for the "errors", "encoding", and "encodings" arguments being
unexpected.
This is the base definition:
def setcontents(self, path, file, chunk_size=64*1024):
This is the Tahoe definition:
def setcontents(self, path, file, chunk_size=64*1024):
This is a temporary version of the Tahoe definition that makes everything work
(though this arguments aren't being handled):
def setcontents(self, path, file, chunk_size=64*1024, errors=None, encoding=None, encodings=None):

I should've been more clear that this error is specific to the Tahoe support.

Where did "encodings" come from?
I've never used Tahoe (so can't test your fix) but it looks like you're correct
in that the setcontents prototype needs to be updated to match

The extra attributes came from the Python3 support. setcontents supports
unicode now. Unfortunately it changed the setcontents signature.
This fix is probably simple enough, but I don't know much about tahoefs myself.

- Changed state: Accepted
So who is going to be responsible for it? I have to make this change
whereever I use it.

There is likely more to it than that change. Not sure when I'll have the time
to look at it. You could post to the mailing list, maybe the original author
can adapt it.
