Robert Muir updated LUCENE-5904:
--------------------------------
Attachment: LUCENE-5904.patch
Patch fixing 3 bugs so far (Lucene40SIWriter, Lucene46SIWriter,
CompoundFileWriter). There might be more bugs: we should review all uses of
Directory.deleteFile to make sure we are doing the right thing.
I also fixed up core tests that currently rely upon e.g. unref'ed files check
or manipulate files directly to disable the option.
I may have made a mistake or unconvered something in disk full test that i
havent investigated yet:

> IndexWriter has logic to handle the case where it can't delete a file (it
> puts in a retry list and indexfiledeleter will periodically retry, you can
> force this retry with deletePendingFiles).
> But from what I can tell, this logic is incomplete, e.g. its not properly
> handled during CFS creation, so if a file temporarily can't be deleted things
> like flush will fail.
