What's the state for Centos? I think it was the last likely distro we cared about with old python needs, but I'm not sure core supports it at all any more.

Thanks Abhilash. What I didn't realize is since I already have a mysql server running on my dev box for other purposes, I had to use that server and create a 'mailman' database within it and then use appropriate credentials to access it. I can now actually run tests using mysql. My results in this case are different from the original issue at <https://gitlab.com/mailman/mailman/issues/385> because my server is not running in "strict" mode., but I can now work on the original issue since I can actually test any fixes. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

Problem getting tox to use mysql
by Mark Sapiro 08 Oct '17

I'm trying to work on the issue <https://gitlab.com/mailman/mailman/issues/385>. I've been unable to make a test fail. I finally discovered that when I run 'tox -e py35-nocov-mysql' or 'tox -e py35-nocov-mysql -- -P hold', tox installs the pymysql dependency, but SQLAlchemy is still using the sqlite dialect when the tests run. It appears I may need a [database] section in some mailman.cfg, but I don't know what I would put there for accessing the database, and I don't know where I'd put the .cfg. Also, isn't this something tox should just do? I do think that when GitLab CI runs the mysql tests it does actually use mysql as I've seen mysql related failures there, but I don't seem to have the magic to make it work locally. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

I'm in favor of dropping Python2. All distros have Python3 and afaik all dependencies are Python3 ready. So I don't see a reason why anybody would want to stick to Python2, especially since core is Python3 only...

Migrating Postorius and Hyperkitty to Python 3
by Abhilash Raj 01 Oct '17

Hi All, Mailman uses Django web framework for the web based frontends, Postorius - The Official UI, and Hyperkitty - The official Archiver. They are both Django "apps" which means that they can be plugged into any other existing Django "project" (aka Django "installation") to work alongside other apps that people might be running. Currently, both the Django apps we have are Python 2 only, we have talked about moving to Python 3 but we decided we want it to be bilingual (support both 2 & 3). The reason we decided that was because if people would want to embed Postorius & Hyperkitty in their installations, they need to be able to run it under whatever python versions they are using. I want to revisit this assumption for being bilingual. Currently, there is no supported version of Django which doesn't support Python 3. Starting from v2.0, set to release in December 2017, Django is going to drop Python2 support. Now, that doesn't mean no one can run Django under Python2, 1.11 (LTS version) supports Python2 and will be supported probably till Python 2 is supported (April 2020 according to [1]). I believe that our (limited) development efforts would be best utilized if we just drop the support for Python 2 in Postorius & Hyperkitty instead of trying to be bilingual. Any day one of our dependencies may decide to do the same, and we would have to then use Python 3 anyway. Also, dropping Python 2 support doesn't seem like a lot of pain for anyone, you just need another instance of Django running, which is not *that* hard using uwsgi (in Emperor mode). I believe most of our dependencies should support Python 3, or should have a good enough replacement if it doesn't. Thoughts?
