[PR] Prevent panic in schema type parser on malformed CompositeType [cassandra-gocql-driver]
SAY-5 opened a new pull request, #1964:
URL: https://github.com/apache/cassandra-gocql-driver/pull/1964
`(*typeParser).parse` indexes `ast.params[count-1]` in the CompositeType branch without checking that any parameters were parsed, so a bare `org.apache.cassandra.db.marshal.CompositeType` (no parameter list) panics with `index out of range [-1]`. `parseParamNodes` has the same problem: after consuming the opening `(` it reads `t.input[t.index]` without a bounds check, so an unterminated type string runs off the end of the input.
Both inputs can reach `parseType` while interpreting `system_schema` validator strings, turning a malformed value into a client crash during schema refresh. This guards the empty-params case and the parameter-list scan so malformed input falls back to the existing unparseable-type path instead of panicking, and adds a regression test.
Fixes #1963.
