Probably you meant s/can/can't/ ... but still, it may not be so dire. It won't happen for Mailman 3.0 but I think it should definitely be a goal for Mailman 3.1 (which will *not* take another 4 years :). I've tried to be very careful in writing Mailman 3 so that *its* code should be relatively easy to port to Python 3. No doubt there will be gotchas, but I am definitely keeping that in mind as I go. >In particular I noticed that lazr.config have been untouched since 2009, >which makes me think that is less likely that they will be ported to >Python 3. > >Is it a valid assumption or there is a porting plan? > >Are there any other blocking factors in general from libraries or other >issues?? Really, we need to get our dependency stack ported. I'm committed to making Mailman 3 a Python 3 application as soon as it's possible. Martin von Loewis was working on porting Storm at Pycon, which obviously is a critical component, but I don't think he quite finished. We need restish.io ported, along with its dependency stack, as well as several of the still-unported Zope libraries, and *their* dependency stacks. By looking in buildout's eggs directory, you can get a good sense of what is currently required: flufl.bounce-2.1-py2.7.egg/ flufl.enum-3.3.1-py2.7.egg/ flufl.i18n-1.1-py2.7.egg/ flufl.lock-2.2-py2.7.egg/ flufl.password-1.2-py2.7.egg/ httplib2-0.7.4-py2.7.egg/ lazr.config-1.1.3-py2.7.egg/ lazr.delegates-1.2.0-py2.7.egg/ lazr.smtptest-1.3-py2.7.egg/ mimeparse-0.1.3-py2.7.egg/ restish-0.12.1-py2.7.egg/ setuptools-0.6c12dev_r88846-py2.7.egg/ six-1.1.0-py2.7.egg/ storm-0.19-py2.7-linux-x86_64.egg/ WebOb-1.2b3-py2.7.egg/ z3c.recipe.scripts-1.0.1-py2.7.egg/ z3c.recipe.tag-0.4.1-py2.7.egg/ zc.buildout-1.5.2-py2.7.egg/ zc.recipe.egg-1.3.2-py2.7.egg/ zc.recipe.testrunner-1.4.0-py2.7.egg/ zope.component-3.12.0-py2.7.egg/ zope.configuration-3.8.0-py2.7.egg/ zope.event-3.5.1-py2.7.egg/ zope.exceptions-3.6.1-py2.7.egg/ zope.i18nmessageid-3.6.1-py2.7-linux-x86_64.egg/ zope.interface-3.8.0-py2.7-linux-x86_64.egg/ zope.schema-4.0.1-py2.7.egg/ zope.testing-3.10.3-py2.7.egg/ zope.testrunner-4.0.4-py2.7.egg/ The flufl packages are of course ported. :) Not all of that will be needed. For example, I do want to eventually get rid of zc.buildout, zope.testing, and zope.testrunner, so some of those dependencies will go away as a result of that. The best way to help is to work with those upstreams to get official Python 3 support in their libraries. If you're looking for guidance, start with storm, WebOb, restish, lazr.*, and the unported zope.* libraries (minus .testing and .testrunner, and possibly .i18nmessageid). The email6 package availability will probably help us a lot too. Help R. David Murray on that package, or just pay him money to finish it. :) Cheers, -Barry _______________________________________________ Mailman-Developers mailing list [email protected] http://mail.python.org/mailman/listinfo/mailman-developers Mailman FAQ: http://wiki.list.org/x/AgA3 Searchable Archives: http://www.mail-archive.com/mailman-developers%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-developers/archive%40jab.org Security Policy: http://wiki.list.org/x/QIA9
