User list in mysql
by Dan Chen April 6, 2000

April 6, 2000

My company has tasked me to port our existing mailing list to mailman. The requirement is that the list of subscribers has to be kept in mysql. (We have scripts and reports that use this list). I'm a python newbie, so please bear with me. I've taken a look at MailList.py and understand that the subscriber list and all other data is stored as a marshal in config.db. And this is stored in the methods Load and Save. I'm proposing that when Save is called, it also makes changes to the mysql db. And after a Load, it queries the db. This sounds very expensive, and I'm wondering if developers here who know Mailman and python better would have a better scheme. Also if I'm missing anything in my analysis. thanks dan

2.0b2 status
by Ron Jarrell April 6, 2000

April 6, 2000

Updated both my production and test servers (no, not in that order) to whatever was in cvs this morning, which at least has me stamped as 2.0beta2... Seems to be working fine, including news gating... I'm watching the logs. Did have one weirdness where the production server was giving me tracebacks on the listinfo page.. Which went away after I tried it a couple of times, while check_perms was running... check_perms found nothing wrong, and the script "healed" itself. Bizarre...

check_perms bug?...
by Dan Mick April 5, 2000

April 5, 2000

Somehow, my /home/mailman/lists directory managed to get set with permissions check_perms didn't check for; it was set to d-wx-ws--x/mailman/mailman, which caused mailcmd to be unable to list the directory (no read perms). I fixed it once I figured it out, but I had a lot of check_perms runs in there before I finally figured it out...mostly because I was confused about what 'x' really means on a directory. But check_perms could have saved me time if it had checked for 'owner-and-group-read'; I think it should.

security szenario possible?
by Adrian Letzner - Sun Germany Berlin SE April 5, 2000

April 5, 2000

i would like to know, if mailman can handle the following szenario: 1. automatic subscribing to a fixed list (eg. via cgi script). that means: a program (eg. cgi-script) should handle the subscribing/unsubscribing mechanism by sending a static mail to the *-request address WITHOUT (!!) using the password mechanism (new privacy option: *not confirming). 2. deleting the mail-header to anonymisize the mails which will be posted. the reasons for that is my plan to have an automatic anonymous mailing list defined, where only the administrator will post messages. please answer directly to me, cause i'm not on the list. thanks a lot and sorry for my english -- ******************************************************************* Adrian Letzner ISV Partner SE Tel: (++49 30) 74 70 96 65 Sun Microsystems GmbH Fax: (++49 30) 74 70 96 99 Lankwitzer Str. 19 mailto:adrian.letzner@germany.sun.com 12107 Berlin http://www.sun.de *******************************************************************

Listing Lists Faster in 2.0?
by Roberto Ullfig April 5, 2000

April 5, 2000

So, in 1.0rc2, displaying the list of lists for 529 lists requires 529**2 = 279841 system stat calls and takes over one and a half minutes on our Ultra-2 2x296 processor system! Is this because of Python, Mailman, or both? Has this been "fixed" in 2.0? You really should only need to make one stat call per list. -- Roberto Ullfig : rullfig(a)uchicago.edu Systems Administrator Networking Services and Information Technologies University of Chicago

Answering my own question
by Dan Mick April 5, 2000

April 5, 2000

Adding a "save_list=0" (or just a fourth argument '0') to the two calls to SetUserOption in admin.py speeds up that "set one option" flag a *whole* lot. It might be that similar "optimizations" to the other forms processing (DeleteMember, primarily) are a bit unsafe, but it seems like a huge win for the SetUserOption calls, and not very unsafe, since the list will be saved after processing all users anyway.

Speaking of pathological behavior...
by Dan Mick April 5, 2000

April 5, 2000

Now that I'm in the same room with my Mailman server, I notice that, at least after setting admin_user_chunksize to 50 (from the default 30) that changing one user's "mailto" flag from off to on (to disable a user by hand temporarily) beats the living *hell* out of the disk, and server. Something bad wrong is going on there; I truss'ed it once and it was continually doing something like opening a file, writing it, and closing it. I don't know what. Something's wrong though. I haven't started to try to look at the form-processing code to see what happens.

But even when withlist is run from Python, PYTHONPATH/sys.path doesn't include /home/mailman/Mailman (this is 1.1): python -i bin/withlist <listname> Loading list: <listname> (unlocked) >>> sys.path ['/home/mailman', 'bin', '/usr/local/lib/python1.5/', '/usr/local/lib/python1.5/plat-sunos5', '/usr/local/lib/python1.5/lib-tk', '/usr/local/lib/python1.5/lib-dynload'] This means that the relatively-obvious "import mm_cfg" doesn't work.

Local characters (loike ÄÖÜß) in pipermail
by Henning Schroeder April 3, 2000

April 3, 2000

Hello, I just modified the latest version of Mailman/pipermail to support local characters (like äöüß). Headers with "=?ISO-8859-1..." are really disturbing :-( Basically my code decodes every message header with the mimify module. Is anyone interested in the source? It modifies Message.py, Mailbox.py, pipermail.py and Hyperarch.py. Besides I would like to implement a better MIME support in Mailman. Then you could e.g. block binary attachments in the list or display HTML-mails with inline-graphics in the archive. Henning
