Michael McCandless updated LUCENE-2762: --------------------------------------- Attachment: LUCENE-2762.patch Patch. I made a new test case showing the problem (and also modified a pre-existing test case to also show the problem). Patch includes the fix (I don't commit the merged segment until after the CFS is built) and both tests now pass. I also added a new core test utility class (LineFileDocs) that's able to read line files produced by contrib/benchmark, and the new test uses this to index the line for Wikipedia. I think we should somehow mark this test to run only at night on hudson eg with a new @nightly tag or something... it's already disabled if it can't find the line file, though it's now hardwired to the line file location in my env. In general I think our tests should sometimes use "real" data so if we can get this wikipedia line file in a standard place on hudson then longer-running @nightly tests can use it... > Don't leak deleted open file handles with pooled readers > -------------------------------------------------------- > > Key: LUCENE-2762 > URL: https://issues.apache.org/jira/browse/LUCENE-2762 > Project: Lucene - Java > Issue Type: Bug > Affects Versions: 2.9.4, 3.0.3, 3.1, 4.0 > Reporter: Michael McCandless > Assignee: Michael McCandless > Attachments: LUCENE-2762.patch > > > If you have CFS enabled today, and pooling is enabled (either directly > or because you've pulled an NRT reader), IndexWriter will hold open > SegmentReaders against the non-CFS format of each merged segment. > So even if you close all NRT readers you've pulled from the writer, > you'll still see file handles open against files that have been > deleted. > This count will not grow unbounded, since it's limited by the number > of segments in the index, but it's still a serious problem since the > app had turned off CFS in the first place presumably to avoid risk of > too-many-open-files. It's also bad because it ties up disk space > since these files would otherwise be deleted. -- 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: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
