The doubled entries issue
I've got the problem Multiple rows were found when one or none was required. I found the issue and a script here: https://gitlab.com/mailman/mailman/-/issues/657
I did su - mailman3 and ran:
python scriptname.py
and got:
Traceback (most recent call last): File "/opt/mailman3/fix-doubled-entries.py", line 21, in <module> listmgr = get_list_manager() ^^^^^^^^^^^^^^^^^^ File "/opt/mailman3/fix-doubled-entries.py", line 6, in get_list_manager return getUtility(IListManager) ^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/mailman3/venv/lib64/python3.11/site-packages/zope/component/_api.py ", line 180, in getUtility raise ComponentLookupError(interface, name) zope.interface.interfaces.ComponentLookupError: (<InterfaceClass mailman.interfa ces.listmanager.IListManager>, '') (venv) 1[mailman3@dalen ~]$
Do I miss something? How can I fix the problem?
Thanks, Lars

I don't have much experience with databases. I did:
sudo -i -u postgres
psql mailman
select * from listarchiver where name = 'mhonarc';
and get:
id | mailing_list_id | name | _is_enabled ----+-----------------+---------+------------- 1 | 2 | mhonarc | f 9 | 4 | mhonarc | f 13 | 5 | mhonarc | f 17 | 6 | mhonarc | f 21 | 8 | mhonarc | f 25 | 9 | mhonarc | f 29 | 10 | mhonarc | f 33 | 7 | mhonarc | f 37 | 11 | mhonarc | f 41 | 12 | mhonarc | f 45 | 13 | mhonarc | f 49 | 14 | mhonarc | f 53 | 16 | mhonarc | f (13 rows)
mailman=#
So which lines should I remove, and how do I do that?
The issue occured after creating a new list and imported from an old 21 list.
Thanks

None of them? You have one entry per mailing list, which is as it should be.
Also, your preceding message doesn't complain about the database, it complains
raise ComponentLookupError(interface, name) zope.interface.interfaces.ComponentLookupError: (<InterfaceClass mailman.interfaces.listmanager.IListManager>, '')
That says that "python scriptname.py" need the IListManager interface but can't find it. You didn't provide enough information to explain why that might be, so I'm not going to guess.
Tell us more about the "duplicate entries" error, and if possible copy it exactly from where you found it originally, including any traceback.
Also tell us more about your installation. Is it a distro installation? If so, which one, what version of Mailman? Is it a venv installation? If so, did you activate the venv before invoking "python scriptname.py"? If you didn't, try that and run scriptname again.

This is mostly because of trying to run script with python scriptname.py
but since it doesn’t initialize the mailman’s zope system.
What you probably want to do is run the script using mailman shell —run
command, which will ensure that it runs the script after initializing the
zope components (and other mailman config and things are initialized too).

Thank you. The script I try to run, is found here: https://gitlab.com/mailman/mailman/-/issues/657
I named the script fix-doubled-entries.py. When I try

Yes, that worked, e.g. no error messages.

Will mailman notify when there's shunted messages?

I see that that's actually expected. In order to run that script with the Python in the venv, you'd need to add
from mailman.core import initialize
initialize.initialize()
to the script to properly set up the Zope components.

That does look like https://gitlab.com/mailman/mailman/-/issues/657, but your database query showed no duplicate mhonarc entries for a list. Possibly, it was a different archiver, or more likely considering
I don't know what fixed the problem, but when I did

it was already fixed when you queried the database.
Will mailman notify when there's shunted messages?
No. I run a daily cron that does ls -lAR /opt/mailman/mm/var/queue/
which lists the shunt queue and the others.

The .pck.tmp and .pck.bak files that are occasionally observed are there to ensure that Mailman can recover if the system goes down while processing a message. The shunt queue is a little different in that nothing is ever done automatically to messages in that queue, there needs to be operator intervention ("unshunt").
Generally you can remove those files if they aren't removed automatically, but if you're concerned you can use "mailman qfile" to examine the content. (You may need to rename to remove the extension .tmp or .bak.)
