> Test suite failures because of Windows file deletion semantics
> --------------------------------------------------------------
>
> Key: LUCY-280
> URL: https://issues.apache.org/jira/browse/LUCY-280
> Project: Lucy
> Issue Type: Bug
> Components: Store
> Affects Versions: 0.4.2
> Reporter: Nick Wellnhofer
> Priority: Minor
>
> There are at least two tests that fail randomly on Windows due to non-POSIX
> file deletion semantics. The problem is that Windows doesn't guarantee that a
> file is deleted immediately if there's another open handle on the file. (I'm
> still not sure what other processes open handles on random files. It might be
> virus scanners, but there are also sources that claim that internal Windows
> services like the Volume Shadow Copy Service are responsible.)
> It's possible that only the test suite is affected but I'd prefer a global
> solution to this problem. I think the best approach is to do something like
> Cygwin: instead of deleting a file, move it to the recycle bin and set the
> delete-on-close flag. Unfortunately, it's rather complicated to implement
> this properly. See the [Cygwin source
> code|https://github.com/mirror/cygwin/blob/master/winsup/cygwin/syscalls.cc],
> functions {{unlink_nt}} and {{try_to_bin}}.
