Listadmin and other alternate interfaces for Mailman
by Terri Oda 07 Nov '12

07 Nov '12

Since I now treat every gathering of hackers as an excuse to get people to tell me things about Mailman, I was chatting with folk at the GSoC mentor summit and my friend V was telling me that she really likes Listadmin as a nicer interface to Mailman: http://freecode.com/projects/listadmin Seems like something I might have to look at and learn some lessons from before we're done with postorius dev. Anyhow, it got me thinking: does anyone here use any other add-ons that they think I should know about? :) I used to have a set of greasemonkey scripts for my own lists, and I'll bet I'm not the only one.

Re: [Mailman-Developers] [Merge] lp:~sophron/postorius/create_users into lp:postorius
by Richard Wackerbarth 25 Oct '12

Isn't the visibility of the list members a per_list policy setting? In any case, we will need to have list administrators (who are not the superuser) be able to see the membership on their list. I think that Postorius will require a better model for roles.

I have just merged them to the trunk. I only made some very small changes and additions (adjusted the docstring in MailmanUserView, added the user icon, some PEP8 fixes...). I also made the user list and details only available to superusers (I don't think every user should be able to see who else is there...).

add_members and nomail
by Scot Hacker 24 Oct '12

24 Oct '12

Back in 2005, while working at an OS X Server-based organization, I wrote a bash + python script pair that extracted students/staff/faculty from a database to populate mailman lists, where many members were subscribed to various lists in nomail mode, using add_member's "-e" flag. The system worked very well. Later, we dropped OS X Server and moved to Linux, and I was surprised to find that my script no longer worked. Only then did I realize that "-e" for "nomail" was an Apple customization that never found its way into the standard Mailman distribution. I solved the problem by copying the Apple-provided add_members to my Linux systems and changing the python shebang at the top. These days, I find myself still doing the same thing on the cPanel-based systems I run, which means my systems break each time cPanel updates Mailman, and that I now run a very old version of add_members. Every organization I've worked for has had this need to batch-add people in nomail mode, which makes it really surprising to me that the standard distribution still doesn't support the option (I can't possibly be the only admin with this need!) Long story short, if I were to submit a patch, would it likely be accepted? Or is there a good reason why it's not included? Thanks, Scot

Logging automatic rejects of incoming posts.
by Mark Sapiro 20 Oct '12

20 Oct '12

When a handler raises Errors.RejectMessage to reject an incoming post, nothing is logged. I have filed <https://bugs.launchpad.net/mailman/+bug/1068837> in preparation for addressing this. My question is what to log. Currently, IncomingRunner logs automatic discards with the message 'Message discarded, msgid: %s'. This is a bit cryptic. I think it would be good to have the list name in this message, but I have never changed it as that could be disruptive. It would also be possible to log which handler raised the exception, but again, that could be disruptive. With a new message for rejects, disruption is not much of an issue as existing log analyzers would presumably not recognize the message and skip it, which is no different from no message, or report the raw message. The question is whether it is a good thing to log the error message that accompanies the exception. This can be quite verbose as the error message can be the list's member_moderation_notice or nonmember_rejection_notice, but if only the handler name is logged, it doesn't distinguish between a non-member reject and a moderated member reject. Does anyone have an opinion on this? -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan

Manipulate mailman in / out queue (from mailman-users)

[Redirecting part of this discussion from mailman-users to mailman-developers. Mark does a great job of explaining the gory details of the queue runners.] On Oct 16, 2012, at 09:23 PM, Mark Sapiro wrote: >First of all, The actual physical size of the queue directory impacts >processing.

I'd like to begin to explore ways to make this automatically more manageable, so that when problems occur (e.g. upstream SMTPd not responding or slow), Mailman can recognize and response more efficiently to the problem. The first question to ask is whether this mostly affects the outgoing queue, or whether other queues *in practice* can suffer the same overloading? I suspect that the incoming queue could get filled quickly if Mailman is slow to handling an onslaught of new messages. My sense is that in general, it's the outgoing queue that gives people the most problems though. The switchboard in Mailman 3 is largely the same as in Mailman 2 (modulo updating the code to more modern Pythons). Before describing my own thoughts, I'd like to open it up and get a sense of your experiences, and strategies you think might help manage big queues. Cheers, -Barry

GHC 12 Open Source Day was amazing!
by Terri Oda 08 Oct '12

08 Oct '12

A very quick report: We had our post-GHC12 hackathon today and I think we were wildly successful. I didn't sit down and count, but we had around 15 women, most new contributors, hacking on Postorius/Mailman today. We stomped on a bunch of the specially-marked bugs, and just as vitally, we had a bunch of folk go through decent first-pass usability testing of the Postorius interface with Robin (who is an experienced UI person from Google) and file bugs for the missing bits that seem most essential for the Postorius release. Sometimes we also filed fixes for the bugs that were tractable in the time we had! Because we were on limited time, I've just got a pile of contributions tarballed up on our dev vm (and backed up elsewhere), and I got everyone who fixed a bug to comment on it on Launchpad so we can send out the appropriate copyright forms. I'll be marking those bugs as fixed once I get home (I need to pack and sleep now) and sometime thereafter (probably next weekend) I'll separate out the code to merge requests and triage the rest of the new bugs so we can start work on those. I think people had a lot of fun seeing their code go live on our test server and watching their bugs get fixed, and I think we've got a few contributors who'll be interested in doing more (and maybe, once I wrangle the travel funds, coming to pycon!). I'm so very excited! :) Terri
