I/O error in Runner.py when archiving under 2.1a3
by Ellen Spertus April 22, 2002

April 22, 2002

A mailing list of mine works except for archiving. Whenever a message is processed, the following error shows up in Mailman's error log: Apr 17 09:29:47 2002 (1253) Uncaught runner exception: [Errno 5] Input/output error Apr 17 09:29:47 2002 (1253) Traceback (most recent call last): File "/usr/local/mailman/Mailman/Queue/Runner.py", line 104, in __oneloop self.__onefile(msg, msgdata) File "/usr/local/mailman/Mailman/Queue/Runner.py", line 152, in __onefile keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/local/mailman/Mailman/Queue/ArchRunner.py", line 70, in _dispose mlist.ArchiveMail(msg) File "/usr/local/mailman/Mailman/Archiver/Archiver.py", line 187, in ArchiveMail traceback.print_exc() File "/usr/local/lib/python2.2/traceback.py", line 210, in print_exc print_exception(etype, value, tb, limit, file) File "/usr/local/lib/python2.2/traceback.py", line 122, in print_exception _print(file, 'Traceback (most recent call last):') File "/usr/local/lib/python2.2/traceback.py", line 13, in _print file.write(str+terminator) IOError: [Errno 5] Input/output error I am using 2.1a3 on Redhat. As far as I can tell, the permissions under /usr/local/mailman/archives/private are correct. Root and mailman have r/w access to everything. When I manually run "./arch sys /usr/local/mailman/archives/private/sys.mbox/sys.mbox" as either root or mailman, the archives are correctly generated. Any suggestions? Thank you. Ellen

My long term goal is for > the changes to be incorporated into Mailman. Barry and I had a discussion by mail about this recently. Basically he has his day job, his real life [tm] and he pretty much maintains mailman by himself, which in other words means he sometimes/often has limited bandwidth. On one side, reviewing other people's code for correctness, and to check whether they really merge right with his grand scheme of things wrt where the code is going to go, takes time. On the other side, he's trying hard to get mm 2.1 out, which obviously should be a higher priority than adding code at this time. Either way, some people will get a bit disappointed, you can't fully win :-) Once 2.1 gets out, we can all release our own patches against it, but I'm hoping it's not going to be like the linux kernel where people now have to deal with applying multiple patches from outside the main distro, possibly with conflicts, or with bugs that they may report as bugs in mailman when the bug is really a bug with the patch Ideally patches that would be of interest to many would go in the main distribution, but I don't think that much more new code is going to hit mailman before the 2.2 cvs branch opens. I've however asked Barry if he would consider code that is reasonably confined (either in the code, or because it can be globally enabled/disabled in Defaults.py). To be fair my mail was much longer than that and probably requires some heavier thinking, making a policy decision, and setting a precedent, so he's still thinking about it :-) My guess is that really specific code that wouldn't get used by many people should probably remain as patches, which won't be as big a problem since less people will have to apply that code, and you're also lesss likely to have to apply two patches like that and work out the conflicts. What makes a patch fit for inclusion in mainstream, or too specific, that's left for the maintainer to decide :-) > It seems my choices are: > - working from a snapshot (what I've been doing) > - getting my own CVS branch I've been working from CVS and moving my patches from time to time, even though it's time consuming, because many bugs got fixed in CVS > Would you be willing to create a CVS branch for me (call it "mills") that > I can write my changes to, merging in fixes from the main branch?

That's a call for Barry to make, I'm just a user and contributer, but I have no CVS access (well, none that I'm supposed to have at least :-D) I don't know how much branches help if they diverge, but if it's a temoparary branch that merges eventually, that could work. Again, Barry's call, and remember that most of his energy is into getting mm 2.1 out :-) Cheers, Marc -- Microsoft is to operating systems & security .... .... what McDonalds is to gourmet cooking Home page: http://marc.merlins.org/ | Finger marc_f(a)merlins.org for PGP key

messed up headers
by Ron Jarrell April 21, 2002

April 21, 2002

Ok, the second occurence of this just happened. Mailman stuffed the entire header into the body of the message, and the message started with a glob of text that looked like: <3CC18918.AFF46174(a)pointecom.net><007f01c1e889$52607020$d9ea79a5@VirginiaGrafton> <012b01c1e88c$6bd6f6c0$8900a8c0(a)carolina.rr.com> Now, those look like message ids that were probably on the list before (at least, they're all from systems that would have posted to that list.) Does outlook express have a habit of doing a news-like "References" style header, like an in-reply-to or something, that collects messageid after message id? Because both times this happened, the message started with a blob of message ids. I wonder if the parser is blowing up on too many continuation headers?

Request mail time zone
by Jon Parise April 20, 2002

April 20, 2002

Is there a reason why the timezone for request messages is always +0000? It seems reasonable to honor the time zone of machine. -- Jon Parise (jon(a)csh.rit.edu) . Information Technology (2001) http://www.csh.rit.edu/~jon/ : Computer Science House Member

And now I must try it. If only I could find a list of every possible MIME type except 'text'.... :) (I'll probably want to hack up another field there, that is "Pass sections that have MIME types matching this...", for bastards like me who want *nothing but text*, thank you...)

Inject has given me problems, unless I go and remove some magic header manually (well, with sed); IIRC, it was X-BeenThere. Here are a couple of scripts I find useful for manually investigating bad or shunt messages: Create symlinks to all the shunted messages' .pck and .db files, in ~mailman, for investigation with debugshunt.py $ cat ~/bin/linkshunt #!/bin/ksh i=0 for f in $(ls qfiles/shunt/*pck); do ip=$(printf %03s $i) base=$(basename $f .pck) ln -s qfiles/shunt/${base}.pck shunt${ip}.pck ln -s qfiles/shunt/${base}.db shunt${ip}.db ((i=i+1)) done Set up some gunge to poke around shunted messages by hand (particularly when they won't parse, so dumpdb is no help). Create a msg object from argv[1], and have a pp function around for pretty-printing various things as you poke, then start an interactive console: $ cat debugshunt.py #!/usr/local/bin/python import sys sys.path.insert(0, './bin') import paths import cPickle import pprint import code f=open(sys.argv[1]) msg=cPickle.load(f) pp=pprint.PrettyPrinter().pprint try: import readline except ImportError: pass namespace = globals().copy() namespace.update(locals()) code.InteractiveConsole(namespace).interact("got console?")
