-------------------------------------------
Summary: Enforce dataDir/instanceDir/ulogDir to be paths that
contain only a controlled subset of characters
Key: SOLR-8873
URL: https://issues.apache.org/jira/browse/SOLR-8873
Project: Solr
Issue Type: Improvement
Reporter: Tomás Fernández Löbbe
We currently support any valid path for dataDir/instanceDir/ulogDir. I think we
should prevent special characters and restrict to a subset that is commonly
used and tested.
My initial proposals it to allow the Java pattern: {code:java}"^[a-zA-Z0-9\\.\\
\\\\\\-_/\"':]+$"{code} but I'm open to suggestions. I'm not sure if there can
be issues with HDFS paths (this pattern does pass the tests we currently have),
or some other use case I'm not considering.
I also think our tests should use all those characters randomly.
