[jira] Commented: (SOLR-716) Support properties in configuration files

["Henri Biestro (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-716?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12625028#action_12625028 ] 

Henri Biestro commented on SOLR-716:
------------------------------------

bq.SolrResourceLoader keeps a reference to the CoreDescriptor
It would seem preferable & possible to only store the properties (versus the CoreDescriptor) in the SolrResourceLoader; this is the only piece needed for evaluation.
IMHO, the CoreDescriptor giving potential access to everything (through the CoreContainer), it should not be shared/stored outside of the SolrCore without careful impact consideration.

bq. users cannot specify a variable inside solr.xml 
You could do a second evaluation pass to expand the property values (if they are property expressions) created for the CoreContainer and for each CoreDescriptor.
If you were though, you'd need to keep the property expression map & the property value map separated.

> # Allows users to define global as well as core-specific properties in solr.xml which can be used in solrconfig.xml and schema.xml
> {code:xml}
> <solr persistent="false">
>   <property name="var" value="value" />
>   <cores adminPath="/admin/cores">
>     <core name="core0" instanceDir="core0">
>       <property name="var" value="value" />
>     </core>
>     <core name="core1" instanceDir="core1" />
>   </cores>
> </solr>
> {code}
> # The following core-specific properties will be added automatically:
> ** solr.core.instanceDir
> ** solr.core.name
> ** solr.core.configName
> ** solr.core.schemaName
> # The variable substitution will be done in this fall-back order -- core-specific, implicit, global, system properties.
> # The properties defined in solr.xml should also be persisted back as is (without evaluation).
