Subject Backwards compatibility warning
Date Thu, 01 Jul 2010 09:58:44 GMT
Folks,

The trunk LCF software is undergoing three major revisions this week, the first of which already
was committed, and the other two which may happen as early as today.

The only non-compatible *functional* change involves how the Solr Connector deals with colliding
metadata - specifically, metadata fields that have the same name as the Solr id field.  Rather
than just shunt the colliding metadata field aside, there is a new tab in all jobs using the
connector that allows you to define a mapping.  You may need to define that mapping on appropriate
jobs, or you may see collisions begin to occur with the new code base.  The documentation
does not yet describe this feature, but will at some point in the future.

The other two changes involve how LCF is built and deployed.  Code for configuration-defined
classpaths will be committed, and also the configuration file will become XML, to allow precisely
enough greater flexibility for configuration-defined classpaths.  This will permit LCF framework
to be built entirely independently of any of its connectors, so the build and distribution
processes too will be changing to reflect this.  Stay tuned.

Karl
