Duplicate test entries introduced during port migration
Low Severity
The newly added test entry at line 39 (jdbc:clickhouse://[::1]:8123) is an exact duplicate of the pre-existing entry at line 41. Similarly, the entry added at line 77 (jdbc:clickhouse://localhost:8123/?custom_key1=val1) duplicates the pre-existing entry at line 88. Both arose from mechanically replacing no-port test URLs with port-explicit versions without noticing identical entries already existed. The old no-port entries tested distinct scenarios; the replacements add no new coverage.

Medium Risk
Breaking change for clients that relied on implicit ports in JDBC URLs; could cause connection failures until URLs are updated.
Overview
Removes JDBC URL default-port normalization in
jdbc-v2soJdbcConfiguration.createConnectionURL()no longer appends:8123/:8443when the port is omitted, relying solely onURI.create(...).toASCIIString().Updates URL parsing tests to require explicit ports in connection URLs (including
jdbc:ch://...) and documents this as a breaking change inCHANGELOG.md(issue #2753).Written by Cursor Bugbot for commit 7879a7d. This will update automatically on new commits. Configure here.
