Description Jose Plans 2007-07-09 11:18:39 UTC
Description of the problem:

Samba 3.0.23 shipped with RHEL5 GA, doesn't handle correctly the changes per
directory notifications. Using the call ReadDirectoryChangesW() seems to fail
against a samba share from RHEL5.
This has been fixed in 3.0.25, see post below :
 * http://lists.samba.org/archive/samba-cvs/2007-February/074022.html
The fix is confirmed by the customer.
Issue has been seen by the customer as they are running an application that
maintains an inventory of the files present in a directory; this application
also allows to open an external editor and modify the directory contents. With
the actual code they weren't able to tell if the directory had changed. (This
application use ReadDirectoryChangesW()).
This works perfectly when using a local harddrive (Windows OS) but fails when
the ressource comes from Samba. We have therefore asked them to try 3.0.25 to
confirm the changes worked for them, it did. 

Let me know if you need more details, I'm attaching a test case and their
configuration file. (Test case to build on Windows).
