Package: logrotate
Version: 3.7.8-6
Severity: normal
In our system, each user may have a developer area within their homedir called
"sites"
(eg "/home/daniel/sites"), as well as a shared directory used for hosting
("/home/apache/sites").
One of our users instead decided to make /home/user1/sites a symlink to the
shared area.
That means that logrotate does rotate the logs once for the real directory, and
once for
the symlink. On the second pass, it will replace the .1 file with the newly
created
file which is usually empty, which means that the rotated logs are all empty.
The logrotate.d file looks like this:
/home/web/sites/*/*.log {
compress
daily
copytruncate
delaycompress
rotate 14
missingok
sharedscripts
notifempty
postrotate
/etc/init.d/apache2 reload > /dev/null
endscript
}
The end results is logs like this:
-rw-rw-r-- 1 www-data www-data 98447 Feb 10 15:21 ws.log
-rw-rw-r-- 1 www-data www-data 0 Feb 10 09:56 ws.log.1
-rw-rw-r-- 1 www-data www-data 20 Feb 6 06:36 ws.log.10.gz
-rw-rw-r-- 1 www-data www-data 20 Feb 5 06:26 ws.log.12.gz
-rw-rw-r-- 1 www-data www-data 20 Feb 4 06:54 ws.log.14.gz
-rw-rw-r-- 1 www-data www-data 20 Feb 10 06:51 ws.log.2.gz
-rw-rw-r-- 1 www-data www-data 20 Feb 9 06:28 ws.log.4.gz
-rw-rw-r-- 1 www-data www-data 20 Feb 8 06:41 ws.log.6.gz
-rw-rw-r-- 1 www-data www-data 20 Feb 7 06:51 ws.log.8.gz
It also seems to skip over every even logfile number except for ".1"
May I suggest using "stat" on the result from glob, to obtain the real path
of the file, and use that when rotating and in the database? I think that
should solve many of the link related issue here.
For now we have solved this by removing the symlink, but maybe others
runs into the same problem. Marking this bug as "normal", since I would
consider this a rare issue.
Let me know if you need any more info
