Hi logback users! After using logback for a few years I've just started trying to use sifting appender. I want to have two messagepricer.${logfileType}.${HOSTNAME}.log (where logfileType is main or workers) (effectivitly statically named) and many msg-123456789.log (dynamically named) logs, one for each message processed. In general this works, apart from two problems: 1) dynamically named logs don't get rolled (they not renamed to dated form and gz into archive dir) 2) the log file is not closed and when I try to manually rename in Windows Explorer I'm told I can't, because of the write lock. Of course I've searched StackOverflow.com, and searched the web, and read the source code, btu nothing has lead me to a solution. So I did a build of trunk (head 3cd6c8ca1142573a2b69e8d2309b31216d764f15) to get logback-1.0.12-SNAPSHOT. I think problem (2) is caused by SiftingAppender waiting 30 mins deciding logs are stale. Maybe this could be configurable. If I make a patch would it be accepted? It has been asked for before, see [1], [2] and [3]. Problem (1) seems to be because when SiftingAppender closes old RollingFileAppenders, the rollover() is not called, and the file just closed as is. I guess this is because during JVM shutdown closing should be fast, and not trigger a rollover? Other people have hit this before, see [4], so it seems like a commonly asked for enhancement. Is there a chance we could add config to RollingFileAppender to enable roll-on-close? You can see my logback.xml at [5]. Apart from my suggested enhancements, is there a way to fix this? Something I've missed Also?: 3) It would be nice if AsyncAppender could fan out to mulitple appenders. Since it only supports one appender I have to have two AsyncAppenders each feeding a different SiftingAppender.
