Ryan McKinley updated SOLR-269:
-------------------------------
Attachment: SOLR-269-UpdateRequestProcessorFactory.patch
* loads UpdateRequestProcessorFactories using the plugin loader stuff from
SOLR-260.
* makes a UpdateRequestHandlerBase class that XML and CSV share.
* loads and configures a chain of InputTransformations.
* moves UpdateRequestProcessor from o.a.s.handler to o.a.s.update
This is the test config:
<updateRequestProcessor>
<factory name="standard" class="solr.UpdateRequestProcessorFactory" />
<factory name="custom" class="solr.CustomUpdateRequestProcessorFactory"
default="true">
<args>
<lst name="name">
<str name="n1">v1</str>
<str name="n2">v2</str>
</lst>
</args>
<transformer class="solr.CustomTransformerNoOp" />
<transformer class="solr.CustomTransformerNoOp" />
<transformer class="solr.CustomTransformerAdd">
<str name="f0">000</str>
<str name="f1">111</str>
</transformer>
<transformer class="solr.CustomTransformerNoOp" />
</factory>
</updateRequestProcessor>
I am not sure we want to make the transformer interface public yet, but it is
here to show how I think it could be handled.
If you like this approach, I'll clean it up some more...

> A simple UpdateRequestProcessor was added to a bloated SOLR-133 commit.
> An UpdateRequestProcessor lets clients plug in logic after a document has
> been parsed and before it has been 'updated' with the index. This is a good
> place to add custom logic for:
> * transforming the document fields
> * fine grained authorization (can user X updated document Y?)
> * allow update, but not delete (by query?)
> <requestHandler name="/update" class="solr.StaxUpdateRequestHandler" >
> <str
> name="update.processor.class">org.apache.solr.handler.UpdateRequestProcessor</str>
> <lst name="update.processor.args">
> ... (optionally pass in arguments to the factory init method) ...
> </lst>
> </requestHandler>
