Subject [jira] Commented: (LUCENE-2726) simulate disk fulls in copyBytes
Date Thu, 28 Oct 2010 13:34:34 GMT


Robert Muir commented on LUCENE-2726:

So the question here, is how to account for the fact that copyBytes might call writeBytes
(like it does today), and not double-count the bytes for disk full.
