Subject [jira] Commented: (LUCENE-2108) SpellChecker file descriptor leak - no way to close the IndexSearcher used by SpellChecker internally
Date Thu, 07 Jan 2010 17:19:54 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2108?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12797691#action_12797691

Achim Heiland commented on LUCENE-2108:
---------------------------------------

It would be nice if the SpellChecker implements the java.io.Closeable interface (Java 1.5)
:-)

> I can't find any way to close the IndexSearcher (and IndexReader) that
> is being used by SpellChecker internally.
> I've worked around this issue by keeping a single SpellChecker open
> for each index, but I'd really like to be able to close it and
> reopen it on demand without leaking file descriptors.
> Could we add a close() method to SpellChecker that will close the
> IndexSearcher and null the reference to it? And perhaps add some code
> that reopens the searcher if the reference to it is null? Or would
> that break thread safety of SpellChecker?
> The attached patch adds a close method but leaves it to the user to
> call setSpellIndex to reopen the searcher if desired.
