I suspect the issue is you just don't have paths and things set right. If you actually want to run Python code, you should run it via Mailman's "bin/mailman shell" (or "bin/mailman withlist" which is the same thing). However, for creating lists and other common tasks, there are subcommands of the bin/mailman command. Run "bin/mailman help" for more info. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan

Fwd: Mailman GSoC Status report due; code checkin due
by Terri Oda 04 Jun '12

04 Jun '12

I failed to bcc all of you on this, so here's the message I sent to Aamir, just for the record. -------- Original Message -------- Subject: Mailman GSoC Status report due; code checkin due Date: Mon, 04 Jun 2012 13:24:16 -0600 From: Terri Oda <terri(a)zone12.com> To: Aamir Khan <syst3m.w0rm(a)gmail.com> Hi Aamir! How's GSoC going for you thus far? We're now starting week 3 and I've got a couple of things I need from you: (1) I need you to mail a status report to the mailman-developers list saying what you've done so far and what you plan to do next week. Probably just a handful of bullet points. If for some reason you're not comfortable with this, you can email me and I'll summarize for the public list. (2) You're supposed to have some code checked in somewhere by the end of today -- can you send me a link? It's ok if it's not merged yet and you're just publishing a personal branch somewhere, but I'd like to see something. Terri

Mailman 3.0 fresh install - problems from python interpreter
by Jessy Kate Schingler 04 Jun '12

hello! i am setting up mailman 3.0 on ubuntu 12.04. but getting errors when i try to work with mailman through the python interpreter. i hope this is the correct list to post to. here are the steps i took: - installed mailman 3.0.0.b1 in a fresh virtualenv - install is happy, all tests pass (Total: 383 tests, 0 failures, 0 errors in 3 minutes 27.980 seconds.) - default mailman.cfg file, stored in top level mailman dir (eg, it's a sibling to the bin/ directory) - basic postfix config, as descibed here: http://packages.python.org/mailman/src/mailman/docs/MTA.html#postfix - start mailman with bin/mailman start (no errors to be seen) then i go to follow the example on how to create new mailing lists: http://packages.python.org/mailman/src/mailman/commands/docs/create.html but attempting to import mailman packages fails, so it seems the python packages aren't installed? so i run `python setup.py install` in main mailman directory. after that, the imports work, but i get an error at the point of trying to call `command.process(FakeArgs)` as described on the create page. the error is as follows: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/jessykate/virtualenvs/mailman/local/lib/python2.7/site-packages/mailman-3.0.0b1-py2.7.egg/mailman/commands/cli_lists.py", line 180, in process else system_preferences.preferred_language.code) File "/home/jessykate/virtualenvs/mailman/local/lib/python2.7/site-packages/mailman-3.0.0b1-py2.7.egg/mailman/core/constants.py", line 53, in preferred_language return getUtility(ILanguageManager)[config.mailman.default_language] File "/home/jessykate/virtualenvs/mailman/local/lib/python2.7/site-packages/zope.component-3.12.1-py2.7.egg/zope/component/_api.py", line 169, in getUtility raise ComponentLookupError(interface, name) zope.interface.interfaces.ComponentLookupError: (<InterfaceClass mailman.interfaces.languages.ILanguageManager>, '') FWIW, i have also installed the postorius interface and all seems to work from this approach. i can even verify that the mailing list i created through the postorius interface shows up when i issue `bin/mailman lists`. any idea on how to fix this error? am i missing something? i tried a few other of the instruction pages in the 3.0 docs and all generated errors of some kind. so perhaps i'm just not importing/installing the packages properly? any help greatly appreciated. thanks, -- Jessy http://jessykate.com

HyperKitty MongoDB vs PostgreSQL.
by Pierre-Yves Chibon 02 Jun '12

Dear all, It has been some time since the last info regarding HyperKitty, but the project has made some progress. I have implemented to database interface that I was presented already a month ago [1]. So now there is a standalone project/library, KittyStore [2] which provides an interface to the database. It defines an interface which can then be implemented for whatever database system you would like. At the moment it covers MongoDB and PostgreSQL. Once I implemented this interface I tried to solve the question of which database system should we primarily focus on. I wrote a small comparison test of the two systems on an RHEL6 system [3] (I still have to publish the results for F17). The difference between the two databases system is not so large (1s for a query that already takes 6 seconds) and there was not any tuning of the servers. So I think the advantage of having only one back-end for mailman and its archive is worth this time difference in the results (which might anyway get even better). Thus we will move forward with PostgreSQL as a back-end for HyperKitty. The good news is that HyperKitty already works fine with PostgreSQL and KittyStore (if you use the correct branch [4]). However, we have to rebuild our test server, so we cannot show you how the latest version works right now. So all is nicely getting in place for Aamir to start working on his project and for HK to get further down the road :) I think that's about all I wanted to say, fire away if you have questions!
