Erik Hatcher commented on SOLR-1725:
------------------------------------
The latest patch also refactors the test case a bit, creating a common base
class for useful stuff borrowed from the field mutating update processor tests.
I'm having issues with the tests in the latest patches. Running "ant
-Dtestcase=ScriptUpdateProcessorFactoryTest test" I get, after it "hangs" for a
couple of minutes:
{code}
[junit4] ERROR 0.00s | ScriptUpdateProcessorFactoryTest (suite)
[junit4] > Throwable #1: java.lang.AssertionError: ERROR:
SolrIndexSearcher opens=3 closes=1
{code}
I've not yet figured out what is causing this, as the test class itself is
fairly straightforward.
Also, testMultipleScripts test case is a bit odd... setting one of the
factories to enabled=false (so it's not really testing multiple, though
awkwardly it actually is anyway for some reason).
Still fiddling, but figured I'd post an updated patch in case anyone else has
thoughts on these issues.

> A script based UpdateRequestProcessorFactory (Uses JDK6 script engine
> support). The main goal of this plugin is to be able to configure/write
> update processors without the need to write and package Java code.
> The update request processor factory enables writing update processors in
> scripts located in {{solr.solr.home}} directory. The functory accepts one
> (mandatory) configuration parameter named {{scripts}} which accepts a
> comma-separated list of file names. It will look for these files under the
> {{conf}} directory in solr home. When multiple scripts are defined, their
> execution order is defined by the lexicographical order of the script file
> name (so {{scriptA.js}} will be executed before {{scriptB.js}}).
> The script language is resolved based on the script file extension (that is,
> a *.js files will be treated as a JavaScript script), therefore an extension
> is mandatory.
> Each script file is expected to have one or more methods with the same
> signature as the methods in the {{UpdateRequestProcessor}} interface. It is
> *not* required to define all methods, only those hat are required by the
> processing logic.
> The following variables are define as global variables for each script:
> * {{req}} - The SolrQueryRequest
> * {{rsp}}- The SolrQueryResponse
> * {{logger}} - A logger that can be used for logging purposes in the script
