Examples of ZODB.event
by Jean-Daniel 12 Feb '13

12 Feb '13

Hello, I would like to build a config repository on the ZODB for an appliance where many processes would boot and talk to at boot to load their configuration. Some processes might modify or add new conf, and some different component should take this change of configuration into account. Is there any ZODB.event example app that I could read from? ZODB.event is a little too low level for me. I wish the subscribers would get a notification message like: - property modified. Ex: '(VideoComponent', 'server_port') - original value, new value. Ex: '8080', '1234' Thanks, bye

zope.security on github?
by Stephan Richter 11 Feb '13

11 Feb '13

Hi everyone, I was just about to start porting zope.security using the SVN version, when I noticed it is already on Github and Tres has even worked on it today. So 2 things: 1. Can we delete the contents of zope.security on svn.zope.org? 2. Can we enable checkin messages for all moved projects? (I have not seen any checkin messages from Tres, for example.) Regards, Stephan -- Entrepreneur and Software Geek Google me. "Zope Stephan Richter"

Porting zope.tal to Python 3
by Marius Gedminas 11 Feb '13

11 Feb '13

I don't plan to write about every package I port, but there were some lessons learned from zope.tal that I thought I should mention. - Running 2to3 on your sources is a good way to identify places that need changing, but you'll have to revert most of the actual changes to keep it compatible with Python 2. I recently learned about a tool called python-modernize[1] that is basically 2to3 except it rewrites into a common Python 2 & 3 subset. I haven't checked it out yet, but it sounds promising [1] http://pypi.python.org/pypi/modernize - StringIO: while Python-3-style io.StringIO() and io.BytesIO() classes exist in Python 2.6+, you can't easily use either them as a replacement for StringIO.StringIO or cStringIO.StringIO. Why? Because people tend to mix native (ASCII-only) string literals with Unicode objects, and that's a no-no in Python 3 land. I didn't like the idea of importing unicode_literals from the __future__, or of dropping u'' prefixes everywhere. Partially because I'm not sure that would be enough -- str objects might make it all the way though the public API of zope.tal and suddenly code that used to work on Python 2 just fine would now explode. So I went with a conditional import -- from cStringIO import StringIO on Python 2 and from io import StringIO on Python 3. - tox/detox make it very easy to add just one more supported Python version -- edit tox.ini, run detox, fix tests. This works with PyPy too, not just Python 3.x! Marius Gedminas -- http://pov.lt/ -- Zope 3/BlueBream consulting and development

Lessons from zope.testrunner
by Marius Gedminas 11 Feb '13

11 Feb '13

I didn't port zope.testrunner to Python 3, but I did make its tests pass (eventually) on 3.2 and 3.3. - If python setup.py test passes, and tox -e py27 passes, and detox indicates that all Python versions also pass all tests --- that might just mean you have a bug in your setup.py that doesn't do sys.exit(1) in case of failures. Oops. - Python guarantees that random.random() will return the same sequence of floats if you initialize the RNG with the same seed. This guarantee doesn't extend to methods like random.shuffle()! Workaround: random.shuffle(a_list, random.random) Note: I'm talking about numeric seeds here. If you use strings as seeds, you'll also have to deal with the different hashing methods: Python 2.x uses hash(your_string), which is already non-portable between 32-bit and 64-bit platforms, while Python 3.2+ uses SHA-512, unless you do random.seed(your_seed, version=1). Anyway, don't use strings as seeds (because 32-/64-bit nonportability of string hashes). Marius Gedminas -- http://pov.lt/ -- Zope 3/BlueBream consulting and development
