Plone on python 3 status

2020 is approaching fast, one day at a time, and besides being a nice catchy year, it will be also the year where Python 2.7 will no longer get any security updates.

What that means for Plone? We should hurry up and get a python 3 porting of the whole stack, yes, including Zope, ZTK, ZODB and all the tooling around (zc.buildout, etc etc).

Fortunately quite some tooling and Zope/ZTK/ZODB is already updated and there’s ongoing effort on porting the remaining parts.

The big elephant on the room blocking any porting effort of Plone to python 3 was RestrictedPython, a python distribution that, quoting itself: provides a restricted execution environment for Python.

Note the past on the previous sentence.

Since RestrictedPython is being worked, now it’s high  time for the other python distributions from Plone to be also made compatible with Python 3. Stay tuned for the Plone Conference 2016 sprint report!

Copy&pasting&adapting a set of scripts to track the progress of the porting for the Zope foundation github organization, results here, I made the same but tracking what Plone 5.1 (including our testing environment) looks like on Python 3:

The code is on collective, so feel free to update the package list.

During the Plone Conference 2016  there is quite some work put on either reducing the amount of dependencies, or updating our stack to use newer (already python 3 compatible) part of the underlying stack.

The clock is ticking and Plonistas all over the world are working hard on it!
