Apache Felix Logback vs Sling Commons Log

[Robert Munteanu <ro...@apache.org>]

Hi,

I noticed that a logback module was recently released in the Felix
project [1].

At a glance it seems to have the same high-level objectives as our own
commons-log implementation, but lacks a number of feature we've built.

Since I'm not that familiar with the codebase, I would like to ask if
the goals are similar and if it makes sense to try and converge the two
modules into a single one, presumably in Apache Felix, as it does not
depend on Sling and can get more community exposure.

Thanks,

Robert

Felix Logback currently supports configuring via logback.xml config
file and if logging needs to be changed then that file would need to
be modified. Compared to that Sling Commons Logback [1] support some
more features and enables configuring appenders via OSGi config and
has a good Web Console integration.

+1

Implementation wise Commons Log does not depend on any Sling feature
(except using sling.home to configure base log directory). So it makes
sense to converge the two

I was thinking about that too - it might make some sense to look into
the log.extension as well as we might be able to package logback with
the launchpad.base and have logging via logback even at framework
start-up this way.

That said, I don't know enough about our current logging features to
say if this is enough to replace what we have. Certainly would be nice
to remove the circular dependencies we currently have in the logging.

Karl
