Ferret talk - Apr 2006 - Ferret failing to rebuild_index - occasionally unable to del

I''m switching all my fulltext searching over to ferret using the 
acts_as_ferret plugin on windows (for development, will be deployed on 
linux).

In my tests I have a setup method as follows to ensure the index is 
reset for each test:

def setup
  Item.rebuild_index
end

This works fine for the initial few tests but then suddenly fails for 
the last few tests when it seems to be failing to delete a file.

Loaded suite E:/rails/thatsprogress/test/unit/item_test
Started
........EEEE
Finished in 8.922 seconds.

  1) Error:
test_search_for_count(ItemTest):
Errno::EACCES: Permission denied - 
E:/rails/thatsprogress/config/../index/test/Item/_j.cfs
....

Full trace included later.

It consistantly does it at this point, and looks like something is 
stopping _j.cfs from being deleted.

Any ideas on what''s going on and how to stop it?

Thanks in advance.



Full trace is as follows:

I have looked at this problem recently but didn''t solve it entirely. I 
suspect that windows is not releasing the files soon enough for the next 
test to work on them.

This post might offer some insight

Most of the tests also fail on Windows with a similar error on the demo 
provided in svn.  I tried adding some sleeps but that doesn''t make a 
difference.

I think windows is locking the file for deletion until the test process 
ends - or something similar.

This problem seems to have been solved with ferret 0.9.2

Unfortunately I still see this problem with both 0.9.2 and 0.9.3.
