Subject [jira] Commented: (LUCENENET-216) FSDirectory.Sync Fix to Ensure Flush to Disk
Date Thu, 12 Nov 2009 16:11:39 GMT

George Aroush commented on LUCENENET-216:
-----------------------------------------

Do we have a final resolution on this or are we putting this off 2.9?  There was a good amount
of discussion on this one in the mailing list, so it didn't get captured here.

> 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.
