Subject [jira] Commented: (LUCENENET-216) FSDirectory.Sync Fix to Ensure Flush to Disk
Date Tue, 10 Nov 2009 05:01:34 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12775285#action_12775285

Michael Garski commented on LUCENENET-216:
------------------------------------------

Interesting point, but what happens to the Mono folks when we move to the 3.5 framework and
utilize native .NET calls that are not supported in Mono?  I don't see the feasibility of
supporting compile time switches as we move forward.

Are there any Mono users of Lucene.Net?

> DIGY and Doug discussed this issue during the 2.9 port, and this is a patch to give 2.9
the expected behavior of actually ensuring the OS flushes it's buffers to disk.  DIGY suggested
using the kernel32 method FlushFileBuffers, and after investigation he was correct!  FileStream.Flush
doesn't do that - the OS could still be caching it.
