added decode() for an rstrip to properly convert it #1793

wants to merge 3 commits into from

5 participants


was getting the following error:

File "/usr/local/lib/python3.3/site-packages/boto/s3/", line 177, in _get_base64md5
return binascii.b2a_base64(self.local_hashes['md5']).rstrip('\n')
nose.proxy.TypeError: TypeError: Type str doesn't support the buffer API

which was fixed with the added decode()


How did you reproduce this error? Can you provide some simple code to show how this is failing?


I got this issue consistently while trying to collectstatic on Heroku (using Python 3.3.2), although I don't have a step-by-step on how to reproduce it.

I previously applied similar changes myself and can verify that sabernar's fix also works for me fwiw.


I get this error when trying to upload from django admin using django-storages-py3.

the pull request fix it for me.

python 3.3
Djnago 1.6.1
django-storages 1.1.8 ported to py3


This has been added to the py3kport branch.
