> Key: SLING-6172
> URL: https://issues.apache.org/jira/browse/SLING-6172
> Project: Sling

> Reporter: Mark Adamcin

>
> I have, a number of times, run into a situation where I need to be able to
> selectively override the AEM default rewriter pipeline based on run mode. I
> read the discussion in a relevant thread
> (http://apache-sling.73963.n3.nabble.com/Configure-rewriter-pipeline-per-runmode-td4022918.html)
> and based on the implementation of ProcessorManagerImpl, it seems that
> extending the observed config resource paths is the most expedient way to
> make this happen without changing the existing behavior with respect to
> config/rewriter paths, and without reimplementing everything for an
> OSGi-config-centric approach.
> The attached patch file introduces a private configuration factory class
> called ProcessorConfigurationMapping that requires only a mapped.path
> property intended to refer to a single rewriter pipeline config node under
> the Resource Resolver search path, but that wouldn't be discovered by the
> current ProcessorManagerImpl implementation.
> The ProcessorManagerImpl has been modified to bind 0..n [static|greedy]
> ProcessorConfigurationMapping instances and to use these mappings to find
> additional config resources during initProcessors() as well as to populate
> the ResourceChangeListener configuration with additional observation paths
> during activation.
> Once activated, the ProcessorManagerImpl treats ResourceChange events on
> these mapped paths just like changes to config/rewriter children.
