Simon Willnauer updated LUCENE-8043:
------------------------------------
Attachment: LUCENE-8043.patch
[~mikemccand] thanks for the review. I did run into some issue with tests and
had do add some more logic around when to drop the docs. I also added an
assertion in IW that pendingNumDocs and maxNumDocs is consistent when we close
the IW. can you look one more time to make sure it's safe. I ran tests and it
looked terrible, failures all over the place. I spent quite some time to get
the accounting right now. I think it looks good now but I could use some help
beasting / reviewing it.

> The IndexWriter check for too many documents does not always work, resulting
> in going over the limit. Once this happens, Lucene refuses to open the index
> and throws a CorruptIndexException: Too many documents.
> This appears to affect all versions of Lucene/Solr (the check was first
> implemented in LUCENE-5843 in v4.9.1/4.10 and we've seen this manifest in
> 4.10)
