Hi everyone,
as the week ends, I thought I might give a brief update on the Python 3 porting effort.
According to the "Unofficial Zope on Python 3 status page"[1], about 110 packages are ported to Python 3.3.
Hanno and I worked this week on updating the ZTK configuration files and I am happy to announce that the ZTK passes all tests on Python 3.3! So once the ZODB is ported, we can start on finalizing all releases, which would pave the way for a ZTK 2.0 release.
Marius has made great efforts on finishing the port of ZODB. All the tests pass now on the py3 branch for Python 2.6, 2.7 and 3.3. He has also removed all resource warnings (he started at 400+). The final task will be to integrate zodbpickle. zodbpickle needs some changes to properly enable the "noload()" method. Luckily this work will entail rewriting the dump/load of persistent ids to be more efficient and compatible with cPickle 2.7 pickles. (We are working hard on making Python 2 pickles load on Python 3!)
On Wednesday, I was able to run a first Zope 3 (or should I say Bluebream?) app on Python 3.3. Thanks to Andrey and Albertas for porting some of the complex application packages. The sample application can be found in ``zope.paste``[2]. Note the short ZCML[3] and Paster[4] files. Thanks goes to everyone who helped breaking unnecessary and circular dependencies to make this work so well!
In the process of all of the above, we have also started moving all packages that we are ported to Python 3 over to GitHub. I have also ported the core packages for Zope 2/4 and Grok already.
So what's next? I am in the process of trying to port a rather large demo application[5] to Python 3. We are about 20 packages (that we control) away from that goal. Andrey is currently working on porting zope.testbrowser to Python 3 by changing its internal implementation from mechanize to WebTest (since it is too hard to deal with mechanize). Also, we will have a serious look at ZEO.
I hope I got some of you interested in thinking about porting applications to Python 3.
Yes! Very exciting update, thank you. And speaking of old libraries supporting Python 3, in case anyone needs PIL with their Python 3 Zope apps, I could use some help testing the soon-to-be-released Pillow 2.0 (PIL fork) with Python 3 support: git://github.com/python-imaging/Pillow.git.
