#89892 — Cannot update OpenSSL for Python3

But when I do:
    import urllib3.contrib.pyopenssl
I get:
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/usr/lib/python3.4/site-packages/urllib3/contrib/pyopenssl.py", line 55, in <module>
        import OpenSSL.SSL
      File "/usr/lib64/python3.4/site-packages/OpenSSL/__init__.py", line 8, in <module>
        from OpenSSL import rand, crypto, SSL
      File "/usr/lib64/python3.4/site-packages/OpenSSL/rand.py", line 9, in <module>
        from six import integer_types as _integer_types
    ImportError: No module named 'six'

When I then give:
    pip3 install -U OpenSSL
It goes wrong:
    Could not fetch URL https://pypi.python.org/simple/OpenSSL/: 404 Client Error: Not Found

I checked and even
    https://pypi.python.org/simple/
does not exist. Anyone an idea what is happening here?

I think what you want is called pyOpenSSL, not just OpenSSL:

https://pypi.python.org/pypi/pyOpenSSL
https://pypi.python.org/simple/pyopenssl/

Not sure why /simple/ doesn't work, but you're not normally meant to
grab that page manually - it's for script work. You could raise a
tracker issue about that if you like, but it may not be considered
important.

Does 'pip3 install -U pyOpenSSL' work?

Not really, because that gives:
    Requirement already up-to-date: pyOpenSSL in /usr/lib64/python3.4/site-packages

I don't know why it wasn't automatically installed, but 'six' is a
listed dependency of pyOpenSSL. What happens if you try to install
six?

That gets installed. And then I get:
    ImportError: No module named 'cryptography'

So I try to install that. This gives:
    Command /usr/bin/python3 -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/cryptography/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-_7jexj87-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/cryptography
Storing debug log for failure in /root/.pip/pip.log

In the log I see:
    c/_cffi_backend.c:2:20: fatal error: Python.h: No such file or directory
     #include <Python.h>
                        ^

Okay, that one's easy enough to deal with!

You have something that needs to build a C extension. To do that, you
need to have the Python headers installed. How did you install Python?
On Debian/Ubuntu family Linuxes, that's probably "apt-get install
python3" - so getting the headers would be "apt-get install
python3-dev". Give that a try, and then retry the pip install.

I should have thought about that myself. :-(

Now I get:

Interesting. I'm not sure why yours is complaining about that; mine
doesn't. (Possibly because I'm running Python 3.5, and stuff may have
been changed.) In any case, this would be a reasonable thing to make a
bug report about. In the meantime, you can simply override that
warning-equals-error parameter:

It looks like I am encircled by Gremlins:
    >>> import urllib3.contrib.pyopenssl
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/usr/lib/python3.4/site-packages/urllib3/contrib/pyopenssl.py", line 58, in <module>

This is looking like a pyopenssl bug - I can't import that name
either, and given that it has the leading underscore, it's probably
not an official part of the socket module's API.

Looks to me as if you have installed a Python 2 version of urllib3? pyopenssl? and are
trying to run that under python 3.

(socket module in python 2 does have a _fileobject, whereas in python 3 it no longer has
it.  Checked in CPython on Windows.)

I did an uninstall and installed it again:
    pip3 install urllib3
    Downloading/unpacking urllib3
      Downloading urllib3-1.10.4.tar.gz (138kB): 138kB downloaded
      Running setup.py (path:/tmp/pip_build_root/urllib3/setup.py) egg_info for package urllib3

        warning: no previously-included files matching '*' found under directory 'docs/_build'
    Installing collected packages: urllib3
      Running setup.py install for urllib3

        warning: no previously-included files matching '*' found under directory 'docs/_build'
    Successfully installed urllib3
    Cleaning up...

But I keep getting the error. Only 2 lines earlier:
    >>> import urllib3.contrib.pyopenssl
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/usr/lib/python3.4/site-packages/urllib3/contrib/pyopenssl.py", line 56, in <module>

Right. This seems to be an issue with the "contrib" module pyopenssl that is provided as
a courtesy with urllib3. The latter is 100% python 3 compatible from what I read in
their docs.

Looking at that contrib module however:
https://github.com/shazow/urllib3/blob/master/urllib3/contrib/pyopenssl.py

In the first few lines in the module docstring it states it is for Python 2.
I guess you won't be able to use this urllib3 contrib module with python 3. Maybe you
can contact its author to ask for a fix?

An alternative is to switch to Windows and do away with this archaic 
concept of users having to build code :)

Showing my complete ignorance of *nix, what is the difference betweeen 
"/usr/lib/python3.4/..." and "/usr/lib64/python3.4/..."?  Simply 32 
versus 64 bit, which can or can't be mixed, or what?
