I tried the "sleep" approach as well. But then I thought that it was not
viable.
I am setting a relatively high number of mailing list that will receive
asynchronous "subscribe" requests via web and/or shell API.
It would be simply not possible to prevent bug this from happening as
the chance of two "subscribe" being processsed almost simultaneously are
not that small...
I also vote for some kind of timing/lock issue.

Hi,
I have been able to reproduce this bug consistently by running the
replicate_bug script:
replicate _bug is the following:
#!/bin/sh
/usr/local/mailman/bin/rmlist testlist1
/usr/local/mailman/bin/rmlist testlist2
/usr/local/mailman/bin/rmlist testlist3
/usr/local/mailman/bin/rmlist testlist4
/usr/local/mailman/bin/rmlist testlist5
/usr/local/mailman/bin/rmlist testlist6
/usr/local/mailman/bin/newlist -q -e url.domain.com testlist1
[EMAIL PROTECTED] testpwd
/usr/local/mailman/bin/newlist -q -e url.domain.com testlist2
[EMAIL PROTECTED] testpwd
/usr/local/mailman/bin/newlist -q -e url.domain.com testlist3
[EMAIL PROTECTED] testpwd
/usr/local/mailman/bin/newlist -q -e url.domain.com testlist4
[EMAIL PROTECTED] testpwd
/usr/local/mailman/bin/newlist -q -e url.domain.com testlist5
[EMAIL PROTECTED] testpwd
/usr/local/mailman/bin/newlist -q -e url.domain.com testlist6
[EMAIL PROTECTED] testpwd
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist1
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist2
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist3
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist4
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist5
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist6
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist1
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist2
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist3
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist4
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist5
echo "[EMAIL PROTECTED]" | /usr/local/mailman/bin/add_members -r - testlist6
After a short wait the following output is received:
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
Subscribed: [EMAIL PROTECTED]
[EMAIL PROTECTED] receives 6 confirmation emails, as [EMAIL PROTECTED] does. S
o far so
good.
At this point testlist1-6 each should contain 2 subscribers: [EMAIL PROTECTED]
and [EMAIL PROTECTED]
BUT
/usr/local/mailman/bin/list_members testlist1
/usr/local/mailman/bin/list_members testlist2
/usr/local/mailman/bin/list_members testlist3
/usr/local/mailman/bin/list_members testlist4
/usr/local/mailman/bin/list_members testlist5
/usr/local/mailman/bin/list_members testlist6
invariably produce some random combination in which one or more of the
subscribers are missing:
for example:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
in which three instances of [EMAIL PROTECTED] are missing...
No Errors in any Mailman log.
Thanks in advance for your help. Please let me know if you need additional
details.
Regards,
Max
I ran the script (after some minor modifications) on
Ubuntu Dapper
Mailman 2.1.11 (self-built package)
Python 2.4.3 (#2, Oct 6 2006, 07:49:22)
and I get similar results:

I then added
sleep 5
after each "add_members" line, and the output looked fine.
I changed the sleep interval from 5 down to 1 in successive
runs, and each output looks fine; each list has the proper two
subscribers. Is there a timing issue here?
