Ferret failing to rebuild_index - occasionally unable to del

Ruby Apps Ferret
1

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.

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.
