Michael McCandless updated LUCENE-6616:
---------------------------------------
Attachment: LUCENE-6616.patch
New patch, it's closer I think. Tests passed once, but I still have one
nocommit ...
I made some drastic changes to IndexFileDeleter (thanks to [~rcmuir] for this
idea!). All places that used to directly delete a file now instead make three
passes:
* First just gather up all files wanting to be deleted, adding them to the
deletable HashSet.
* Second, try to delete all the segments_N files in that set.
* Finally, delete all non-segments files, only if 2nd pass succeeded.
This ensures that even in the presence of a virus checker, the index is never
left in a state where a segments_N is referencing a non-existent file.
I also fixed all file deletion done by IW to use IFD's methods, and made
IFD.deleteFile private.
> IndexWriter should list files once on init, and IFD should not suppress FNFE
