This page tracks the progress of Python 3 effort porting for OpenStack.
Contents
Python 3
Why should OpenStack move to Python 3 right now?
- Python 3 is usually seen as the new Python version which breaks compatibility and raises new Unicode issues. Python 3 is much more than that. It’s a new clean language which has a more consistent syntax. It has many new features, not less than 15 new modules. Python 3 is already well supported by major Linux distributions, whereas Python 2.7 reached its end-of-life. Slowly, some bugs cannot be fixed in Python 2.7 anymore and are only fixed in the latest Python 3 release. Python 3 is now 5 years old and considered as a mature programming language.
Port Python 2 code to Python 3
OpenStack project chose to use the same code base for Python 2 and Python 3. The Six: Python 2 and 3 Compatibility Library helps to write code working on both versions.
References to port Python 2 code to Python 3:
- Porting to Python 3 Book by Lennart Regebro, especially the Language differences and workarounds.
- HOWTO: Porting Python 2 Code to Python 3 by Brett Cannon
- Porting Python Code to 3.x
- python-incompatibility: Demonstrates incompatibilities between Python versions.
Python 3 of OpenStack Depedencies
Blocker Pointer: it's not yet possible to specify different list of dependencies for Python 2 and Python 3. For example, mox only works on Python 2, mox3 can be used on Python 3.
- Julien Danjou proposed to add requirements-py3.txt: openstack/requirements patch and openstack-dev/pbr patch
- An alternative is to support markers in requirements (in pip): pip issue: Support markers in setup(install_requires)?
OpenStack Dependencies:
- mox: use mox3 or port tests on mock which works on Python 3 (mock has been integrated in Python 3.3 as unittest.mock)
- eventlet: not available on Python 3 yet, alternatives: asyncio (Tulip for Python 3.3+/Trollius for Python 2), Tornado
