Ceki, So I gave it a shot. - CloseTBRP.java<https://github.com/trothwell/logback-test/blob/master/src/main/java/org/trothwell/lbtest/CloseTBRP.java> - TestCloseTBRP.java<https://github.com/trothwell/logback-test/blob/master/src/test/java/org/trothwell/lbtest/TestCloseTBRP.java> I'm running into a few problems if you have some time to take a look: - I'm unable to delete files after stopping LoggerContext. - Output file count is off (SiftingAppender or RollingFileAppender doesn't create both output files) - NullPointerException occurs when stopping LoggerContext with CloseTBRP in use I have two scenarios. 1. Create a normal TimeBasedRollingPolicy configured for compression that will create 2 output files. 2. Create the new auto-close CloseTBRP that will do the same. For both configurations this is the steps: (or look at unit test) 1. Create new LoggerContext 2. Configure LoggerContext 3. Submit a log event 4. Set MDC property for discriminator 5. Submit a log event 6. Stop LoggerContext 7. Check log file counts 1. for TBRP, 2 text files 2. for CloseTBRP, 2 zip files Have a great weekend, -- TJ On Fri, Nov 4, 2011 at 9:59 AM, ceki <ceki@qos.ch> wrote:
Hi TJ,
It's a problem which has not been considered previously. Nice problem description btw. One solution would be to subclass TimeBasedRollingPolicy and override the stop() method so that it compresses the current log file. It should not be too hard to do. Ask for help if you run into trouble.

Hi,
I'm using SiftingAppender on top of an appender that uses compression. When using a variable (like username) that will show up more than once, it works great. But when using a session id which is unique, then the log file will not be triggered for compression leading to larger disk usage. Is there a way to go about triggering the file to be compressed when the SiftingAppender closes the child appender after it's timeout period?
