Erick Erickson commented on SOLR-8725:
--------------------------------------
[~anshumg] I made this a blocker in response to the move to cut 6.0 to be sure
we consciously decide to include this or not...
The revised regex is a little easier to understand I think, but whatever....
Maybe a comment about what the purpose of the regex is (i.e. exclude a hyphen
as the first character)?
And maybe add the fact that they cannot _start_ with hypens to the
getIdentifierMessage?
> Cores, collections, and shards should accept hyphens in identifier name

> In SOLR-8642, hyphens are no longer considered valid identifiers for cores
> (and collections?). Our solr instance was successfully using hyphens in our
> core names, and our affected cores now error with:
> marc-profiler_shard1_replica1:
> org.apache.solr.common.SolrException:org.apache.solr.common.SolrException:
> Invalid name: 'marc-profiler_shard1_replica1' Identifiers must consist
> entirely of periods, underscores and alphanumerics
> Before starting to rename all of our collections, I wonder if this decision
> could be revisited to be backwards compatible with previously created
> collections.
