Package: rsyslog
Version: 3.18.6-4
Severity: important
Tags: patch
The rsyslog package (and some others) install an extension conf
file at /etc/logrotate.d/rsyslog .
This file makes a noble effort at triggering rsyslog to start a
new file after rotation:
postrotate
invoke-rc.d rsyslog reload > /dev/null
endscript
However, it seems the environment in which the postrotate script
executes does not allow invoke-rc.d to be found via the path.
This can be easily reproduced by configuring logrotate to trigger
on a small file size with the 'delaycompress' option. Set up a
loop to generate log messages, and watch ls -lht on the directory.
Run logrotate manually, or have cron run it every minute to speed
the repro. Observe that logrotate rotates the files, but syslog
continues writing to the same filehandle (the file now ending
in .1).
One solution is to simply specify an absolute path for invoke-rc.d:
postrotate
/usr/sbin/invoke-rc.d rsyslog reload > /dev/null
endscript
Another solution might be to patch logrotate to use a login shell:
- logrotate.c(102): if (write(fd, "#!/bin/sh\n\n", 11) != 11 ||
+ logrotate.c(102): if (write(fd, "#!/bin/sh -\n\n", 11) != 11 ||
but that could have other effects and is probably outside the scope
of this bug.
Other packages (ones I don't have installed) are probably affected,
I don't know the best way to track them down and bug them.
Thanks,
