Philosophically, I'm not really sure why the flexibility of a full-featured logging system (JULI, log4j, etc.) is required for access logging: there's not much opportunity to use all the features they provide (log level filtering, log-message aggregation to log files and log-file multiplexing/splitting). Access logs typically log one thing (accesses), log it all the time, and always write to the same log file.
I'm not adverse to the patch, I just don't really see a need for it.
I was coming from the "I'd rather not maintain a bunch of code to solve a problem that the logging frameworks have already solved (threading, roll-over, output to multiple destinations)" angle.
That's something I hadn't really thought about, honestly. It's one of the best reasons to use a logging framework IMO.
I'd like to see some performance metrics, though, since putting a fully-fledged logging framework in the middle here has a distinct possibility of slowing everything down (for every request, of course). I kind of like Konstantin's idea of building extension-points into the AccessLogValve to allow a particular implementation of the Valve to handle the physical logging aspects while the AccessLogValve itself takes care of actually generating and emitting the log messages. That way, users can get the best of both worlds.
You know me, always happy to delete some code from the Tomcat code base.
Amen, brother.
Multiple implementations certainly doesn't lead to that end, but we'll see how things shake out.
My main point is that it is something worthy of discussion. And that is what we are doing.
Absolutely.
