Summary: Using SPI lookups of analysis components results in factories that don't get ResourceLoaderAware.inform called on them (When using ClassicIndexSchemaFactory) Key: SOLR-16203 URL: https://issues.apache.org/jira/browse/SOLR-16203 Project: Solr Issue Type: Bug Security Level: Public (Default Security Level. Issues are Public) Affects Versions: 9.0 Reporter: Chris M. Hostetter Ok ... this is a weird one ... SOLR-13593 modified {{FieldTypePluginLoader}} to add the ability for analysis Factories to be resolved by SPI name (ex: {{{}name="stop"{}}}, instead of by "short class name" (ex: {{{}class="solr.StopFilterFactory"{}}}. The code that deals with this just calls (for example) {{TokenFilterFactory.forName(name, params);}} and uses the resulting factory "as is" – But these means that nothing calls the {{inform(ResourceLoader)}} on any factories that implement {{ResourceLoaderAware}} (such as {{StopFilterFactory}} or {{{}SynonymGraphFilterFactory{}}}) In the "short class name" code path (the only option prior to 9.0), the {{SolrResourceLoader}} is used to initialize the Factory, and {{SolrResourceLoader..newInstance(...)}} takes responsibility of calling {{factory.inform(this)}} on everything it instantiates that implements {{ResourceLoaderAware}} (as well as some other checks: like {{{}SolrCoreAware{}}}) This discrepancy means that when using the {{name="foo"}} syntax, many factories won't be fully initialized – or fail on invalid input – during schema initialization. In the case of things like {{StopFilterFactory}} or {{SynonymGraphFilterFactory}}) the problem will manifest as some type of runtime error when the factory's {{create(...)}} method is called as part of creating a new index or query Analyzer. ---- _*...BUT...*_ ---- This problem only seems to manifest itself when using {{ClassicIndexSchemaFactory}} -- which is why it's not readily apparent when using the default configset, or something like {{bin/solr -e techproducts}} (but is trivial to reproduce in testcases (since almost every "test" solrconfig uses {{ClassicIndexSchemaFactory}}) I have no idea _why_ using {{ManagedIndexSchemaFactory}} doesn't manifest the same problem -- it should be using the same {{FieldTypePluginLoader}} under the covers -- but clearly something specific to {{ManagedIndexSchema}} is taking responsibility for calling {{ResourceLoaderAware.inform(...)}} -- This message was sent by Atlassian Jira (v8.20.7#820007) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@solr.apache.org For additional commands, e-mail: issues-h...@solr.apache.org
