The real issue here seems to be that the import from mm_cfg done in the driver script is inadequately protected. The driver script print_traceback definition contains try: from Mailman.mm_cfg import VERSION except ImportError: VERSION = '<undetermined>' This is fine if there is an ImportError exception, but since mm_cfg.py is edited by users, it is possible (likely) that there will be a SyntaxError error exception here, and something more meaningful than the "Mailman experienced a very low level failure and could not even generate a useful traceback for you." message could be reported. -- Mark Sapiro <msapiro(a)value.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

TypeError: cannot concatenate 'str' and 'NoneType' objects
by Ron Jarrell July 26, 2005

July 26, 2005

Ok, I think I managed to screw myself.. Long time ago, I updated to the cvs snapshot, and forgot to set tags, so I got 2.2a0. I finally had time to try to straighten the mess out and "upgrade" to 2.1.6 (which I pulled with tag Release_2_1-maint, so it's post tarball). Bouncer.py keeps blowing chunks knocking out a variety of functions. An example from disabled: /usr/local/bin/python -S /home/mailman/cron/disabled Traceback (most recent call last): File "/home/mailman/cron/disabled", line 220, in ? main() File "/home/mailman/cron/disabled", line 204, in main mlist.sendNextNotification(member) File "/home/mailman/Mailman/Bouncer.py", line 270, in sendNextNotification msg['Subject'] = 'confirm ' + info.cookie TypeError: cannot concatenate 'str' and 'NoneType' objects I'm guessing something in one of the list structures isn't defined right now? Is there perchance a simple fix with withlist I could make? Update, sadly, doesn't do it, even though I forced it. -Ron

XML-RPC CGI interface to Mailman
by Joseph Tate July 26, 2005

July 26, 2005

In case it got missed, and for anyone who is interested in integrating and testing what's currently available, I've posted my XML-RPC patch to SourceForge: http://sourceforge.net/tracker/index.php?func=detail&aid=1244799&group_id=1… I forsee only a pair of changes: First of all many more exceptions should be caught by the handler and real error messages returned through the XML interface. I'll be filling these in over the next few days/weeks. And second, I am going to fix list_lists so that it does not return private lists. I'll keep the patch at the above site up to date. Another thing on the TODO list for after the patch is incorporated: Create an interface to "get" a specific list setting (like config_list -o) -- Joseph Tate Personal e-mail: jtate AT dragonstrider DOT com Web: http://www.dragonstrider.com

I'm having a go at this. I'm not sure how that's supposed to work, though. I've built Mailman 2.1.6 with Python 2.4.1, and it didn't work when installed with Python 2.4.1, and run along side Python 2.4.1 I've built Mailman 2.1.6 with Python 2.2.3, and it works fine. Doesn't matter whether I have Python 2.2.3 or 2.4.1. I'm trying again - but why would config.status do anything? Well, blimey. Everything seems hunky-dory now.

SMTP authentication
by Jeffrey Borkent July 25, 2005

July 25, 2005

Hi All, We are trying to use our authenticated SMTP server headers to ensure people cannot spoof email addresses in mailman. We want to insert a script which when inserted into the mailman.aliases file will check for authentication and insert a header, then use maiman to check for this header and send/discard. How in python do i parse a whole email into an email.Message() object? I can seem to do it in pieces but not as a whoile email.

Hmm, is that because the build process looks for existing codecs in <prefix>? I can't take down Mailman while I build the new version - it takes too long, and Mailman is too important for our business. And, I don't work nights! Similarly, I can't mess with the current installation in order to make the new one build. I have to make a new build, test it, then deploy it. If deployment takes a couple of minutes to take down the service, move some links, then bring it back up, that's OK. Actually, that raises an issue. When I install Python, it kindly installs in eg /local/lib/python2.4 - then it moves a link to enable the new installation. It would be very nice if Mailman would do the same. Taking down my list server while building the new one isn't practical. Especially when I can't be sure the new one will work. I found I have to: build (configure, make, make install) with <prefix> = /local/mailman-2.1.6. test the web pages (fixing apache config to find the cgi) configure with <prefix> = /local/mailman hack the Makefile to install in /local/mailman-2.1.6 make, make install link archive, log, queue directories take down mailman link /local/mailman put mailman back up Now, this process is kind of workable, but has these drawbacks: 1. it's more complex than it should be 2. I never get to test what I finally install - it has to be rebuilt 3. It takes much longer than it should. >> >> Let us know if that works and I'll update the release notes. Ah, well that'll have to wait, I'm afraid. I've downgraded Python to 2.2.3, and reinstalled Mailman. Seems to work just fine. We don't use Python for much else, so I'm not desperate to update it. >> -Barry -- Ian Eiloart Servers Team Sussex University ITS

XML-RPC interface to mailman
by Joseph Tate July 24, 2005

July 24, 2005

I've created a patch to Mailman to add XML-RPC based remote procedure calls to mailman. This is just a first cut to show that it can be done and to do a few basic operations I need to plug it into a kind of hosting framework so it can be controlled from a separate web server. I plan to add functionality to it to fully meet my needs, but I thought I'd throw it out there so that I can get some feedback. It's made against a pristine 2.1.6 tarball. In order to reuse code, I had to refactor quite a few files. Most notably some of the Cgi interfaces that do real work were tied very closely to the idea that you want to output HTML. You don't with XML-RPC, so I split out the work from the formatting and replaced said formatting with some exception handling. I welcome comments on this part of the patch. I'd like to know how to make this better. You can see that I handle authentication in each XML-RPC call that needs it, so it shouldn't be any less secure than the appropriate Cgi call. Finally, I'd like some discussion of licensing. I think that the xmlrpc.py file itself should be LGPL just so that there is no ambiguity whatsoever about using XML-RPC calls from a non-GPL application. However part of me thinks that this is unnecessary because there is no import required to use XML-RPC, and therefore, calling these functions would not be considered "linking" in any technical sense of the word, and therefore would not require making the calling application GPL.

Mailman and Semantic Web

July 24, 2005

Hi, I'm a computer engineer that I'm working in a project to export a mbox file into an RDF extension, in order to give the possibility of constructing some powerful ideas around it. The possibilities (search, stats, etc) are enormous. I'm developement it in python, and I would like to work in a line that soon me of the possibility of integrating it easily with mailman (¿pipermail?). I think that it's and interesting feature. Then I would talk with someone about some design questions. Who are the developers of pipermail?
