logrotate compress files after the postrotate script

Question

I have an application generating a really heavy big log file every days (~800MB a day), thus I need to compress them but since the compression takes time, I want that logrotate compress the file after reloading/sending HUP signal to the application.

/var/log/myapp.log {
    rotate 7
    size 500M
    compress
    weekly
    postrotate
        /bin/kill -HUP `cat /var/run/myapp.pid 2>/dev/null` 2>/dev/null || true
    endscript
}

Is it already the case that the compression takes place after the postrotate (which would be counter-intuitive)? If not Can anyone tell me if it's possible to do that without an extra command script (an option or some trick)?

Thanks Thomas

Answer 1

Adding this info here in case of anyone else that comes across this thread when actually searching for wanting a way to run a script on a file once compression has completed.

As suggested above using postrotate/endscript is no good for that.

Instead you can use lastaction/endscript, which does the job perfectly.

Answer 2

The postrotate script always runs before compression even when sharedscripts is in effect. Hasturkun's additional response to the first answer is therefore incorrect. When sharedscripts is in effect the only compression performed before the postrotate is for old uncompressed logs left lying around because of a delaycompress. For the current logs, compression is always performed after running the postrotate script.
