Don't do that. It won't work anyway because the locked list object in
ArchRunner will be saved after you're done and will undo any changes you
made to your list object. But, as I say, you shouldn't need to save your

Hello again !
I think I found what's the problem is :
the script works now, but as I write my own archiver, it doesn't do the
pipermail part (i.e. update mails in archive)... I thought that this code :
mlist = MailList.MailList(maillist, lock=False)
msg = email.message_from_file(sys.stdin, Message.Message)
f = StringIO(str(sys.stdin))
h = HyperArch.HyperArchive(mlist)
h.processUnixMailbox(f)
f.close()
did all, but after reading a bit of code, it doesn't exactly. It saves to .mbox
file, right ?
I tried to find where it does the pipermail stuff, but it's a bit complicated
[I'm not so at ease with Python].
Any clue ?
Thank you

At this point, you have a list object (locked) and a message object. You
might think you could just do
mlist.ArchiveMail(msg)
to archive the mail to the listname.mbox file and the pipermail archive,
but that wouldn't quite work because that method would re-invoke the
external archiver. Also, you don't need to worry about the listname.mbox
file because the ArchiveMail() method already did that before invoking
the external archiver, so what you would need is
from Mailman.Archiver import HyperArch
from cStringIO import StringIO
f = StringIO(str(msg))
h = HyperArch.HyperArchive(mlist)
h.processUnixMailbox(f)
h.close()
f.close()
Which is what the ArchiveMail() method would do. Now you still have the
mlist and msg objects, and you need to save and unlock the list at some
point
mlist.Save()
mlist.Unlock()
and the message is now in the pipermail archive and can be indexed.
Hello again,
I'm having some troubles with my code. According to what Mark said, I've
done this :
#!/usr/bin/env python
import sys
sys.path.insert(0,'/usr/lib/mailman')
import syslog
syslog.syslog('begin script')
import email
from Mailman import MailList
from Mailman import Message
## archive part
from Mailman.Archiver import HyperArch
from cStringIO import StringIO
maillist = sys.argv[2]
hostname = sys.argv[1]
msg = email.message_from_file(sys.stdin, Message.Message)
syslog.syslog(maillist)
mlist = MailList.MailList(maillist, lock=True)
syslog.syslog('processing archiver')
## let archive it
f = StringIO(str(msg))
h = HyperArch.HyperArchive(mlist)
h.processUnixMailbox(f)
h.close()
f.close()
mlist.Save()
mlist.Unlock()
mlist.ArchiveMail(msg)
Here is one problem. Remove the above line. As I tried to say above you
can't do this. The lines above from f = StringIO(str(msg)) through
f.close() archive the message. When you call mlist.ArchiveMail(msg),
it reinvokes your external archiver in an endless loop.
You need to remove the mlist.ArchiveMail(msg).
The locking problem is something else. The external archiver is called
with the list locked, thus when we try to instantiate the list 'locked',
we have a deadlock. Thus, you never saw the loop because of the deadlock.
The good news is we don't have to pass a locked list instance to
HyperArch.HyperArchive() as it uses a special archiver lock.
So, replace
mlist = MailList.MailList(maillist, lock=True)
with
mlist = MailList.MailList(maillist, lock=False)
and remove the mlist.Unlock() as your instance isn't locked, and
ArchRunner will unlock its list instance when you exit.
syslog.syslog('processing indexer')
### coming soon
syslog.syslog('exiting - all ok')
sys.exit(0)
syslog is for debug purpose only.
And if I send an email on my ML, I have this kind of error:
Mar 02 12:38:33 2010 (28380) toto.lock lifetime has expired, breaking
Hmm, it seems it crashes in pipermail.py, in function processUnixMailbox:
we have a
pos = input.tell() on line 564, but unfortunately input does NOT have any
tell() method...
It returns a 41 status.

Hello again,
First of all, I want to thank you for the time you spend on my case. I really
appreciate.
Now, for my code:
I attached the latest (buggy) version of my archive-and-index.py script. I've
done a rollback to the way you told me, so that we won't go in all directions.
You'll find anotther attachment : debug file I added in this way :
PUBLIC_EXTERNAL_ARCHIVER = '/root/archive-and-index.py %(hostname)s
%(listname)s /var/log/mailman/archiver'
It seems that the Message.Message stays, even if we create a new StringIO
variable... weird.
Just in case :
python --version
Python 2.5.2
Maybe there's a problem with this version... ? If so, it will be a little
problem, as it's the lenny version.
I'll keep on trying, and keep you updated as soon as I have some new things.
Thanks again.
Best regards,
C.

I'm trying to create a xapian[1] indexer for our mailing list. As
mailman is written in Python and there are python bindings for
xapian, I guess I can maybe create a plugin for that. My first
question is : is there already such a thing ? I searched on the
net, but nothing appeared My second one : can we create a plugin
for mailman, if so, where should I go to have some doc ? seems
there's nothing in the wiki
(http://wiki.list.org/dosearchsite.action?searchQuery.queryString=pluginsearchQuery.spaceKey=conf_all)
Just to explain why I'd like to do that: we already have a xapian search
engine in here, indexing a fileserver, request tracker queues and
moinmoin wikis... so we'd like to aggregate all our stuff in one app for
searching.
This will be quite doable with Mailman 3 which is still in
development.
There are problems trying to do this in Mailman 2.1.x. There is a
plugin capability of sorts in the form of custom handlers that can
be added to the incoming message processing pipeline. See the FAQ
at http://wiki.list.org/x/l4A9. However, archiving is
asynchronous with incoming message processing, so it is not
possible for a custom handler to know the URL that will ultimately
retrieve the message from the archive.
A different approach which might be workable is to use the
PUBLIC_EXTERNAL_ARCHIVER and PRIVATE_EXTERNAL_ARCHIVER hooks. If
you set
PUBLIC_EXTERNAL_ARCHIVER = '/path/to/script.py'
PRIVATE_EXTERNAL_ARCHIVER = '/path/to/script.py'
in mm_cfg.py, then that script will be invoked do do the archiving.
The script in turn could invoke the standard pipermail archiving
process and then invoke xapian to index the archived message.
Hello again,
Just one question : what do mlist, msg, msgdata stand for ? As I read
I've to create my module and define a process(mlist, msg, msgdata)
inside it, I'd like to know what are those objects. I discovered that
mlist stands for a Mailman.MailList.MailList('list-name'), but for
the others, it's a bit hard to find...
Only custom handlers need to define process(mlist, msg, msgdata). That
is the entry point to the handler and three objects are passed
mlist is the Mailman.MailList.MailList() instance for the current list
msg is a Mailman.Message.Message() (subclass of email.Message.Message)
instance for the current message
msgdata is a dictionary of the message metadata accumulated so far.
The important thing is these are passed in as arguments to the handler
process() function.
In your case, you are defining a module which is going to be invoked
like the following.
Suppose that
PUBLIC_EXTERNAL_ARCHIVER = '/path/to/myarch.py %(hostname)s %listname)s'
It will be invoked in a pipe similar to
cat raw_message | /path/to/myarch.py HOST LIST
i.e. the command string with %(hostname)s and %listname)s replaced by
the actual host name and list name of the list will be invoked and the
message piped to it.
So, it could begin something like:
#!python
import sys
sys.path.insert(0, 'path/to/mailman/bin')
# The above line can be skipped if myarch.py is in Mailman's
# bin directory.
import paths
import email
from Mailman import MailList
from Mailman import Message
msg = email.message_from_file(sys.stdin, Message.Message)
mlist = MailList.MailList(sys.argv[1], lock=True)
At this point, you have a list object (locked) and a message object. You
might think you could just do
mlist.ArchiveMail(msg)
to archive the mail to the listname.mbox file and the pipermail archive,
but that wouldn't quite work because that method would re-invoke the
external archiver. Also, you don't need to worry about the listname.mbox
file because the ArchiveMail() method already did that before invoking
the external archiver, so what you would need is
from Mailman.Archiver import HyperArch
from cStringIO import StringIO
f = StringIO(str(msg))
h = HyperArch.HyperArchive(mlist)
h.processUnixMailbox(f)
h.close()
f.close()
Which is what the ArchiveMail() method would do. Now you still have the
mlist and msg objects, and you need to save and unlock the list at some
point
mlist.Save()
mlist.Unlock()
and the message is now in the pipermail archive and can be indexed.
Hello again,
I'm having some troubles with my code. According to what Mark said, I've done
this :
#!/usr/bin/env python
import sys
sys.path.insert(0,'/usr/lib/mailman')
import syslog
syslog.syslog('begin script')
import email
from Mailman import MailList
from Mailman import Message
## archive part
from Mailman.Archiver import HyperArch
from cStringIO import StringIO
maillist = sys.argv[2]
hostname = sys.argv[1]
msg

maillist = sys.argv[2]

msg = email.message_from_file(sys.stdin, Message.Message)
syslog.syslog(maillist)
mlist = MailList.MailList(maillist, lock=True)
syslog.syslog('processing archiver')
## let archive it
f = StringIO(str(msg))
h = HyperArch.HyperArchive(mlist)
h.processUnixMailbox(f)
h.close()
f.close()
mlist.Save()
mlist.Unlock()
mlist.ArchiveMail(msg)
Here is one problem. Remove the above line. As I tried to say above you
can't do this. The lines above from f = StringIO(str(msg)) through
f.close() archive the message. When you call mlist.ArchiveMail(msg),
it reinvokes your external archiver in an endless loop.
You need to remove the mlist.ArchiveMail(msg).
The locking problem is something else. The external archiver is called
with the list locked, thus when we try to instantiate the list 'locked',
we have a deadlock. Thus, you never saw the loop because of the deadlock.
The good news is we don't have to pass a locked list instance to
HyperArch.HyperArchive() as it uses a special archiver lock.
So, replace
mlist = MailList.MailList(maillist, lock=True)
with
mlist = MailList.MailList(maillist, lock=False)
and remove the mlist.Unlock() as your instance isn't locked, and
ArchRunner will unlock its list instance when you exit.
syslog.syslog('processing indexer')
### coming soon
syslog.syslog('exiting - all ok')
sys.exit(0)
syslog is for debug purpose only.
And if I send an email on my ML, I have this kind of error:
Mar 02 12:38:33 2010 (28380) toto.lock lifetime has expired, breaking
Woops, right. it was commented out in my code. For now, I'm pocking around with
some other problems, such as my external archiver returns a non-zero status. It
seems to crash with the
h.processUnixMailbox(f)
Is there any way to have a backtrace of python errors (i.e. testing it through
the shell)? I guess I can write a file with all email content, included
headers, and pipe it in my file. Right ?
Thank you!
C.

This will be quite doable with Mailman 3 which is still in development.
There are problems trying to do this in Mailman 2.1.x. There is a
plugin capability of sorts in the form of custom handlers that can be
added to the incoming message processing pipeline. See the FAQ at
http://wiki.list.org/x/l4A9. However, archiving is asynchronous with
incoming message processing, so it is not possible for a custom
