Subject [jira] [Commented] (LUCENE-3147) MockDirectoryWrapper should track open file handles of IndexOutput too
Date Sun, 29 May 2011 17:22:47 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13040828#comment-13040828
] 

Michael McCandless commented on LUCENE-3147:
--------------------------------------------

Ahh OK it is in fact necessary.  It's because closeMergeReaders is also called from the finally
clause when there is an exception (hence the suppressExcs=true), and checkpoint is NOT then
called from that location, so we do need to call it inside here.  Alternatively we could always
call it inside closeMergeReaders, but then not above (inside commitMerge()).  Or we can leave
it be for now :)

> MockDirectoryWrapper currently tracks open file handles of IndexInput only. Therefore
IO files that are not closed do not fail our tests, which can then lead to test directories
fail to delete on Windows. We should make sure all open files are tracked and if they are
left open, fail the test. I'll attach a patch shortly.
