Rei Shapira updated LUCENE-7843:
--------------------------------
Description:
DirectoryReader.listCommits expects FileNotFoundException and
NoSuchFileException while trying to read a specific commit file - if these are
thrown then the code handles this gracefully and that specific commit file is
not returned in the list of all commits for that directory.
LUCENE-7662 changed the behavior of SegmentInfos.readCommit to not throw these
exceptions anymore, but rather throw CorruptIndexException instead.
This causes the code in DirectoryReader.listCommits to never encounter the
previous two exception types, thus throwing the CorruptIndexException all the
way to the top, instead of gracefully handling a few missing commit files.
This breaks how Luke does a clean index operation when listing all of the
commits and then proceeding to delete any files inside the index directory that
were not mentioned by any of the commits.
