[Mailman-Users] Scripts Associated with Log File Rotation

Hi There,


I have been studying the mailman code this morning to find a way to do some
processing when the mailman logs are rotated.  My goal is to process the
data in /var/log/mailman/subscribe.1 and /var/log/mailman/bounce.1 just
after they are rotated.  I reviewed the file /etc/logrotate.d/mailman on my
RHEL system which seems to control rotating the logs - below is a copy of
the file for reference.


/var/log/mailman/bounce /var/log/mailman/digest /var/log/mailman/error
/var/log/mailman/post /var/log/mailman/smtp /var/log/mailman/smtp-failure
/var/log/mailman/qrunner /var/log/mailman/locks /var/log/mailman/fromusenet
/var/log/mailman/subscribe /var/log/mailman/vette {




        /usr/lib/mailman/bin/mailmanctl reopen >/dev/null 2>&1 || true




I have a couple of question about doing what I need to without breaking


(1)   The time stamps of the log files on my system are not all the same.
The time stamp of /var/log/mailman/subscribe.1 and /var/log/mailman/bounce.1
are not even on the same day.  This implies that rotation for these files is
happening at different times.  I'm concerned about making one change to the
logrotate.d file above - like adding a line to the postrotate section - as a

(2)   My first concern leads me to break subscribe and bounce into separate
entries in the logrotate.d file.  Is the solution to what I am trying to
accomplish as simple as the following:

a.      Append the existing logrotate.d file to itself two times - resulting
in a file that has three logrotate sections

b.      Delete bounce and subscribe from the first section

c.      Delete all but bounce from the second section & add my script to run
against bounce.1 just before endscript

d.      Delete all but subscribe from the third section & add my script to
run against subscribe.1 just before endscript.

e.      This implies mailmanctl will run three times for each invocation of
logrotate - it only runs once with the distribution file due to
sharedscripts.  Is this OK?


Thanks for your assistance with this & helping me not break anything as I
make this enhancement to our production system, Greg
