Robert Muir updated LUCENE-6299:
--------------------------------
Attachment: LUCENE-6299_addIndexes.patch
Here is a patch for addIndexes.
we return an error before we do any copying, and don't allow any overflows.
The test is kinda evil in the way it cheats, but its fast and does the job.
disk full testing in general was broken for addIndexes in case of FSDir,
because MockDir would delegate optional copyBytes method directly, and not
count those bytes. Instead this mess of optional methods is cleaned up, so that
MockDir checks everything, but when we run tests with the "raw" dir, we
delegate everything directly to it (except close, for checkindex).
