[Bug 1964881] Re: Logging/Log rotation does not work for catalina.out

How are you running logrotate? Because the problem was that it could not
be truncated by rsyslog running as `tomcat` user.


Anyway, I checked your branch and your fix looks quite similar to mine. The only difference is that I had `fileOwner="syslog"` in `debian/rsyslog/tomcat9.conf` but that is inconsequential. As my setting was redundant, because the default fileowner for rsyslog is `syslog`. (in Ubuntu). So I could say, yes it works :)


That said, it is sad that there is a delta. I think this could be avoided if Debian maintainers would agree on using `root:adm` in their side and Ubuntu defaults to `syslog:adm`. As the default fileOwner is `root` for Debian and it is for Ubuntu in rsyslog. The logrotate also defaults to `root` in Debian and `syslog` in Ubuntu. But maybe it is too difficult to co-operate in this level. I do not know...

Title:
  Logging/Log rotation does not work for catalina.out

Status in tomcat9 package in Ubuntu:
  In Progress
Status in tomcat9 source package in Focal:
  Confirmed
Status in tomcat9 source package in Jammy:
  Confirmed

Bug description:
  In Ubuntu 20.04, with `tomcat9-9.0.31-1ubuntu0.1` (latest) package, `logrotated` is not able to write to `/var/log/tomcat/catalina.out`
  This could be fixed in a newer package but was not backported:
  https://bugs.launchpad.net/ubuntu/+source/tomcat9/+bug/1861881

  In Ubuntu 22.04, with `tomcat9-9.0.58-1` (latest)  package,
  `logrotated` is not able to rotate `/var/log/tomcat/catalina.out`

  Because the `catalina.out` is created with `syslog:adm` ownerships.
  `syslog` user does not have enough permissions to change this.

  This causes following error:

  rsyslogd: error during config processing: omfile: chown for file
  '/var/log/tomcat9/catalina.out' failed: Operation not permitted
  [v8.2112.0 try https://www.rsyslog.com/e/2207 ]

  At the same time, the  `/etc/logrotate.d/tomcat9` has `su tomcat adm`
  directive. Therefore the `logrotated` is not able to truncate the
  `/var/log/tomcat/catalina.out`

  This causes logrotate to copy the contents of `/var/log/tomcat/catalina.out` to as if it would be rotated. As `catalina.out` is never truncated, each rotated file ends up having the contents of `catalina.out` from the beginning of the tomcat installation. This causes the log sizes to keep increasing as no actual log rotation is being done.
