--------------------------------
Summary: SolrIdentifierValidator accepts empty names
Key: SOLR-9016
URL: https://issues.apache.org/jira/browse/SOLR-9016
Project: Solr
Issue Type: Bug
Components: Server
Reporter: Shai Erera
SolrIdentifierValidator accepts shard, collection, cores and alias names
following this pattern:
{code}
^(?!\\-)[\\._A-Za-z0-9\\-]*$
{code}
This accepts an "empty" name. This is easily fixable by changing the {{\*}} to
{{+}}. However, it also accepts names such as {{..}}, {{,__---}} etc. Do we not
want to require collection names to have a letter/digit identifier in them?
Something like the following pattern:
{code}
^(\\.)?[a-zA-Z0-9]+[\\._\\-a-zA-Z0-9]*$
{code}
That pattern requires the name to start with an optional {{.}} followed by a
series of letters/digits followed by the rest of the allowed characters.
What do you think?
