Python dependencies + CentOS 6

[Kris Lou]

Cornielius,

We're having trouble upgrading from 1.5x to 2.3 in CentOS 6.  What are the python dependencies for 2.3?

Thanks,

Kris Lou

Hi Kris,

please note, that you need to run the database migration when upgrading
from 1.5 to 2.3.
The database migration will migrate the token table. It will not
reliably migrate the configuration table, since the configuration was
split from one single flat table to a more sophisticated database
structure. I.e. you might need to recreate your resolver and realm.

The dependencies are denoted in the requirements.txt file.
https://github.com/privacyidea/privacyidea/blob/master/requirements.txt

Kind regards
Cornelius

We get this when running pi-manage.py under Python 2.6, CentOS 6+:

/opt/privacyIDEA2/lib/python2.6/site-packages/cryptography/__init__.py:25: DeprecationWarning: Python 2.6 is no longer supported by the Python core team, please upgrade your Python.

No problems with Python 2.7, but upgrading Python is not fun.

Hi Kris,

I am really not sure if it will run with python 2.6!

So it does not like api/policy.py:523:

# combine static and dynamic policies
keys = static_pol.keys() + dynamic_pol.keys()
pol = {k: dict(static_pol.get(k, {}).items()

+ dynamic_pol.get(k, {}).items()) for k in keys}

We could however combine the two dictionaries in another way, but
I am not sure if there would be other locations it would break.
It is not actively tested with python 2.6

(Honestly I had bad conscience because it did not run under python3)

So what do you suggest?

Kind regards
Cornelius

This breaks PI for CentOS 6, which has support for another 5 years!

Well, my personal preference is to utilize repos whenever possible, but there's obviously exceptions.  I suppose the first question is, what version(s) of Python are most compatible?

Hi Kris,

privacyIDEA definitively does not run with python 2.6.
The change from 1.5 to 2.0 was a major rewrite and the decision was made
for a more modern and reliable design, which came with some
dependencies, so that 2.6 can not be supported anymore, easily.

I know, that it runs on 2.7.3, 2.7.6 and 2.7.9. So take it, that it runs
with 2.7.x

It is correct, that CentOS has up to 10 years of support of _one_
_release_. This is the main idea behind CentOS.

This is not the idea behind privacyIDEA.
I understand that in certain cases having a longer support is necessary.
(You probably could get BUGFIXING for privacyIDEA 1.5 for ten years,
too)
But this can not be assured by such an open source project. And again
this is not the main scope of this project.

And this is why there is professional Support available, to cover all
those needs.

Nevertheless, you might take a look at pythonbrew, install 2.7 in a
local directory and create a virtualenv with 2.7.

Kind regards
