[jira] Commented: (LUCENE-2255) IndexWriter.getReader() allocates file handles

[ https://issues.apache.org/jira/browse/LUCENE-2255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12831095#action_12831095 ] Jason Rutherglen commented on LUCENE-2255: ------------------------------------------ You're not the first to report this... I wonder if we should also do a weak ref type of dealie that auto closes the reader for users who aren't calling IR.close? To answer the question, yes, close on IR must be called. I can't directly do anything about the javadocs so I'll leave that for Mike. > IndexWriter.getReader() allocates file handles > ---------------------------------------------- > > Key: LUCENE-2255 > URL: https://issues.apache.org/jira/browse/LUCENE-2255 > Project: Lucene - Java > Issue Type: Bug > Components: Index > Environment: Ubuntu 9.10, Java 6 > Reporter: Mikkel Kamstrup Erlandsen > Attachments: LuceneManyCommits.java > > > I am not sure if this is a "bug" or really just me not reading the Javadocs right... > The IR returned by IW.getReader() leaks file handles if you do not close() it, leading to starvation of the available file handles/process. If it was clear from the docs that this was a *new* reader and not some reference owned by the writer then this would probably be ok. But as I read the docs the reader is internally managed by the IW, which at first shot lead me to believe that I shouldn't close it. > So perhaps the docs should be amended to clearly state that this is a caller-owns reader that *must* be closed? Attaching a simple app that illustrates the problem. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscribe [at] lucene For additional commands, e-mail: java-dev-help [at] lucene
