Subject [jira] [Commented] (LUCENE-3147) MockDirectoryWrapper should track open file handles of IndexOutput too
Date Thu, 26 May 2011 13:21:47 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13039697#comment-13039697

Simon Willnauer commented on LUCENE-3147:
-----------------------------------------

Shai I have a couple of comments

 * first good catch! :)
 * reenable the FIXME is awesome
 * in DefaultSegmentInfosWriter you might want to change the try / catch blocks to a simple
try / finally if (!succes) out.close(); for simplicity
 * in MockDirectoryWrapper#addFileHandle(io, name) you create an exception that always says
"Unclosed IndexInput" which should say IndexOutput if the handle is an index output. I think
this could be very confusing if you run into bugs there.

> 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.
