Erick Erickson updated SOLR-8308:
---------------------------------
Attachment: SOLR-8308.patch
Patch with tests. Did you know we didn't have any test for a core rename?
Anyway, first Git patch so let's see if I did it right.
precommit and test pass, does anyone see any reason not to commit? This changes
one bit of behavior, you can't rename with bogus core names. It does _not_
affect cores that already exist with bogus names though, so shouldn't break
existing installations.
> Core gets inaccessible after RENAME operation with special characters
