The S3 library needs to be updated (And ideally moved to a better code repository like github.com):

Anyway, here is the current warning from Python 2.6:

This deprecation warning comes up in Python 2.6.2:

S3.py:16: DeprecationWarning: the sha module is deprecated; use the hashlib module instead
import sha

Just change
{{{
#!python

import sha
}}}
to

{{{
#!python

import hashlib
}}}

and then use hashlib.sha1()

Re: Amazon S3 Library for REST in Python ++ ACL policy parsing and creation

I updated the s3.py file to account for the changes in python 2.6. I also noticed that there was no object parsing support for ACL lists nor was there any way to create an ACL using an object approach.

I added a few additional classes and xml.sax handlers to parse the ACL lists. There are also some classes for creating ACL policies from scratch.

I also embedded the unit tests in the file for compactness but, of course, they don't need to be there for production use.

Awesome Paul.

I'm considering this page to basically be dead - the AWS CMS is kind of ... not so great.

I moved the file where everybody can get at it, modify it, make tickets, etc....

Paul,

Can you clarify the addition of the copyright?

# (c) 2009 Tartan Solutions, Inc

This won't be usable on most libraries I'd like this integrated into if you're claiming copyright. It's fine, I just need to know so those changes aren't propagated to the GPL libraries that use s3.py.

Cheers,
Adam

After careful consideration, I recommend all users use boto instead for a python s3 library as this library is no longer actively maintained:

http://boto.s3.amazonaws.com/index.html
http://code.google.com/p/boto/

It's not immediately obvious to a new Python user what to do when starting with S3 and Amazon Web Services, but boto is far and away the superior library.
