setup.py fails for versions of requests prior to 0.10.0 & suggested fix about bokeh

[pzwang]

Thanks for the detailed write-up, Tim. I just installed requests 0.9.3 and am using it to test a modified setup.py, but I can't even get the JS from Github:

Python 2.7.3 |AnacondaCE 1.3.0 (x86_64)| (default, Jan 10 2013, 12:10:41)

Off the top of my head, I think that is caused by 0.9.3 not having the latest certificate required to validate against github. My guess is that the requests package 0.8.2 on Linux had it's certs updated by the packager. Also, what version of OS X are you running and if it's 10.8 do you have GateKeeper switched off?

I had hoped that github would serve the pages under http not https, and i thought i verified that it could, but I guess that's not true, We should change the url to use https, it makes it a bit faster without the redirect.

[timburgess]

Makes sense. If you're able to push up a branch, I can try it on the same Linux box and a Mac with OS X 10.7 Timewise I think my day is starting and yours is ending :-)

[pzwang]

OK, here's a branch: https://github.com/ContinuumIO/Bokeh/tree/fix_setup_requests

I'm happy to bump the minimum Requests version number, but you're on an LTS of Ubuntu and ran into this problem, so I'd rather make it compatible with older Requests.

[timburgess]

To avoid the original error, we also need to f.write as UTF-8 encoded so I've created a pull request for that. With this change in, the install runs OK on both the Ubuntu 12.04 LTS with Requests 0.8.2 and an OS X 10.7 machine with Requests 1.1.0

Plus the get should go to https as http to the github url simply 301's to https as pointed out previously

[pzwang]

D'oh, yeah I forgot to do the encode, which is kind of the point of the whole thing. :-) Thanks!

@pzwang has this been fixed?

[damianavila]

The minimum required version of requests in our setup.py is 1.2.3, so I am closing this one...
