Gregory Chanan updated SOLR-6145:
---------------------------------
Attachment: SOLR-6145v2.patch
SOLR-6145-tests.patch
Two patches:
The tests patch is just taking the existing test as a template and testing
copyFields and adding fields via POST. I verified that these tests fail
consistently without the patch.
The v2 patch handles the copyfields and adding fields via POST cases. The POST
case has a bit of extra logic for making the optimistic concurrency control
failure look like what would happen if the concurrent schema changes were
actually serialized.
> Concurrent Schema API field additions can result in endless loop
