firstSearcher Listener of SpellChecker can be never called ----------------------------------------------------------
Key: SOLR-2425 URL: https://issues.apache.org/jira/browse/SOLR-2425 Project: Solr Issue Type: Bug Components: spellchecker Affects Versions: 1.4.1, 3.1, 4.0 Reporter: Koji Sekiguchi Priority: Minor mail thread: http://www.lucidimagination.com/search/document/65e73468958faf09/known_problem_firstsearcher_event_of_spellchecker_is_never_called firstSearcher Listener of SpellChecker is never called when there is no <listener event="firstSearcher"/> registered in solrconfig.xml. The reason is because the sequence of procedures in SolrCore constructor: # initListeners(); # getSearcher(false,false,null); => register (general) firstSearcher listener if it exists # call SolrCoreAware.inform(); => register SpellChecker's firstSearcher listener After that, Callable.call() is called to execute the firstSearcher event: {code} if (currSearcher==null && firstSearcherListeners.size() > 0) { future = searcherExecutor.submit( new Callable() { public Object call() throws Exception { try { for (SolrEventListener listener : firstSearcherListeners) { listener.newSearcher(newSearcher,null); } } catch (Throwable e) { SolrException.logOnce(log,null,e); } return null; } } ); } {code} At the time, firstSearcherListeners includes SpellChecker's firstSearcherListner, registered by procedure 3 above. But if you have no <listener event="firstSearcher"/> registered in solrconfig.xml, at the procedure 2, searcherExecutor.submit() is never called because firstSearcherListeners.size() is zero at the moment. -- This message is automatically generated by JIRA.
