It's not useful if the addresses are available from the archives or by subscribing to the list. (Actually, a really sophisticated spammer might want to attack by spoofing frequent posters on the assumption they're more trusted and more read, but that seems second-order to me.)

George, let me throw in some thoughts just to annoy you ;) Like with most statistical data I mostly see the figures being used to give statements on quantity - top poster, number of threads etc. Do you think it would be possible to also make some statements on quality? Let me give an example: Mailing lists are often places where people go to ask for advice. Someone asking usually starts a thread and continually keeps replying. That easily makes a person top poster and might make the same person a thread starter, but number of posts and threads started gives no indication of that persons knowledge (concerning the mailing lists topic). OTOH someone who has been on the list for ages, who replies more often than starting threads and who ends threads often after she has replied might very well be a very knowledgeable person, because she gives the one answer that solves the problem. Do you think it would be possible to deduct such quality oriented statements? p@rick P.S. Do you also plan to deliver a tool that analyzes a mailing list archive in order to gather your statistical data? Having the statistical data might be a good reason for people to upgrade their MMx installation to MM3. * George Chatzisofroniou <sophron(a)latthi.com>: > The following document is the lowest level of my design concept.

Speaking about kitties (or archivers)
by Pierre-Yves Chibon 06 Jun '12

06 Jun '12

Meeow miaou* We spoke on IRC about the archiver the other day and I said that I should present here my thoughts about it. So here they are (beware that might be long). First I think we should think about the structure/architecture of things. We have a number of component which need to be archives aware, without being exhaustive I'm thinking about: - the archiver itself (which present the archive (ie: mails and threads) - the NNTP bits which should be able to return emails and/or threads - the stats module which want to give information to the user about the health of the list itself (emails/month, last threads, biggest threads...) - archives retrieval (we probably want to give the user a way to download the archives since the creation of the list/the last year/month) All of these components needs to be aware about the archives. We agreed that the core does not want to know about it. So we have several solutions: - each module becomes an "archiver" wrt to core, meaning each module has its own way to storing the archives (and eventually its own system to do so) - we create a archive-core module which manage the archives and provides an API to access, modify, extend them. Of course, we prefer the second solution :) So we would have the following architecture: mm-core (handles the lists themselves) --send emails to archivers--> archive-core (store the emails and expose them through an API) --> archivers/stats/NNTP The questions are then: - how do we store the emails ? - how do we expose the API ? - how to make it such that it becomes easy to extend ? (ie: the stats module wants to read the db, but probably also to store information on it) Having played with mongodb (HK relies on it atm), I quite like the possibilities it gives us. We can easily store the emails in it, query them and since it is a NoSQL database system extending it becomes also easy. On the other hand, having the archiver-core relying on the same system as the core itself would be nicer from a sysadmin pov. I have not tried to upload archives to a RDBMS and test its speed, but for mongodb the results of the tests are presented at [1]. The challenge will be speed and designing an API which allow each component to do its work. I think it would be nice if we could reach some kind of agreement before the GSoC starts (even if we change our mind later on) to be sure that if we get students their work don't overlap too much. The second point I want to present is with respect to the archiver itself. At the moment we have HyperKitty (HK), the current version: - exposes single emails - exposes single threads - presents the archives for one month or day - allows to search the archives using the sender, subject, content or subject and content - presents a summary of the recent activities on the list (including the evolution of the number of post sent over the last month) I think these are the basis functionality that we would like to see in an archiver. But HK aims at much more, the ultimate goal of HK is to provide a "forum-like" interface to the mailing-lists, with it HK would provide a number of option (social-web like) allowing to "like" or "dislike" a post or a thread, allowing to "+1" someone, allowing to tag the mails or assign them categories. These are all nice feature but, imho, they go beyond what one would want from a basic archiver. So what I would like to propose is to split HK into a sub-project (MiniKitty?) which would provide these basic functionality. We would keep HyperKitty as a more extensive archiver and try to bring HK to its ultimate goal. This will need some more work and time as we will have to make HK speak with core for authentication, find a way to send emails to core/the lists and of course add all the other features (tags, categories...) Comments welcome :) Thanks, Pierre [1] http://blog.pingoured.fr/index.php?post/2012/03/16/Mailman-archives-and-mon… * Hi everyone

I would think quality metrics would be usefully presented via the same application as quantity metrics. It would be interesting to correlate quality and quantity, for example. Do you mean to say "this is out of scope of my project?" As much as I'd like to see quality metrics provided, I'd have to agree with you that it's out of scope of your project (maybe you could do one or more quality metrics on a time-permitting basis at the end of the period).

HyperKitty MongoDB vs PostgreSQL.
by Pierre-Yves Chibon 01 Jun '12

01 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!

Not all of us know what "social_auth" is, and since Postorius and HyperKitty are independent apps, presumably there will need to be some design and coordination effort to get everybody on the same page. In the spirit of "DRY" (don't repeat yourself), rather than make long posts here, I suggest that you start a blog or a Wiki page on the Mailman site where you can log (1) your design decisions and (2) any agreements on APIs etc you make with other Mailman developers (or third parties such as maintainers of libraries you use). Then you can simply have a shortcut key and say "I've designed an authentication mechanism for HyperKitty users, which I expect to be extensible for use by Postorius and other Django apps for Mailman. See my blog: http://blogs.example.com/~aamir/gsoc/." George is doing this quite well IMO. Kudos to George! N.B. George is generally copying his blog post to this list. That's OK if you want to do it, but IMO not necessary. (But that's something we will evolve over time, and I defer to Terri's opinion on this kind of thing. This is all just a suggestion.)

I have had discussion > with few mailman developers about it. I am planning to wrap up > social_auth into mm_ui_auth django application. Both postorius and > HyperKitty can use this app for authenticating users. As you know, Postorius already uses django-social-auth. Implementing it was more or less a configuration issue (settings.py), plus we had to build a login-template (which was pretty trivial). We did look at some other existing solutions before choosing django-social-auth. So far it seems like a good choice. (Although it should be noted, that there was one report about a browserID logged-in user getting logged-out erroneously. But I haven't been able to reproduce this.) Since social-auth has been designed with DRY/re-usability in mind, the important question (at least to me) is: What are the advantages of an mm_ui_auth app wrapper compared to simply using it directly? The main advantage I can think of is shared UI-resources (template, css). But this reduces mm_ui_auth more or less to a "theme only" app (OK, with a few lines of login/logout view code in it). This can make absolute sense, but mainly if both Postorius/HK are OK with sharing the same design for the login-/out pages. I, for one, would be fine with that. (Well, let's see how it looks first. But still... ;-) Cheers, Florian

Re: [Mailman-Developers] [Bug 1006345] [NEW] Anonymous subscription via confirmation email
by Richard Wackerbarth 30 May '12

I think that it is important for this to be controlled an administrative list policy setting. When someone logs in using BrowserID, for example, and then subscribes to a new mailing list, the subscription can be marked as "email confirmed". But if they simply enter an email address on a form, the website need to be able to trigger the issuance of a "request subscription confirmation" email.

HyperKitty login

Hi everybody! First task I am going to do for my GSoC project is to have login authentication mechanism for HyperKitty users. I have had discussion with few mailman developers about it. I am planning to wrap up social_auth into mm_ui_auth django application. Both postorius and HyperKitty can use this app for authenticating users. Feel free to suggest if you have any ideas about how login should work in HyperKitty. -- Aamir Khan | 3rd Year | Computer Science & Engineering | IIT Roorkee
