We don't support python3 yet (also, protobuf is out of our control!)

[sedletsky]

But is there some wip-branch or plans or nothing abot pthon3 rightnow?

[seancribbs]

@mikhailsedletsky I intend to look at it after the Riak 2.0 features are landed, probably in early January. Any assistance in the meantime is appreciated, but I really want compatibility with both 2.6/2.7 and 3 if possible. We have customers using 2.x.

[shuhaowu]

Since google's protobuf does not support python 3 yet... the only compatible fork is https://github.com/openx/python3-protobuf

I can use that to see if there is anything in the riak-python-client code base that fails py3 requirements. This is probably the last library that I need to port to python3 for projects I'm doing.

[sedletsky]

Okay, using python3-protobuf (with tens patches over riak & riak_pb) I built it for python3, but even ping doesn't work (who would doubt). At this point it looks far from production state for python3 (maybe as much as python3 itself).

[shuhaowu]

Does Python 3 work with the http client?

No, but there is no big troubles with, I think. Just need to be ported & moved to http.client.

[yvsong]

Protocol Buffers v2.6 supports python 3.

[hazen]

@yvsong That's great news! I was wrapping up work on on porting the Python client to use https://pypi.python.org/pypi/python3-protobuf, but if the official client supports Python 3, that would be much better. I'll investigate.

[hazen]

Sadly it looks like Google's 2.6.1 still isn't Python 3 friendly, so we'll stick with python3-protobuf for the time being

[yvsong]

I don't know the details but doesn't the last line in the following page say "Support for Python 3"?
https://github.com/google/protobuf/releases

[hazen]

@yvsong It sure does. I tried to install 2.6.1 both from PyPI and from source, but the installer is still 2.x-based. It looks like Python 3.x support is not quite ready yet: protocolbuffers/protobuf#7

[hazen]

The Python 3 issue has been addressed by #379 and will be featured in a forthcoming release
