Aug 1, 2025Monthly summary for 2025-08: Delivered two high-impact items in Hibernate ORM that improve reliability, developer experience, and business value for CockroachDB deployments. Key changes include INSERT RETURNING support in the CockroachDB dialect to retrieve auto-generated IDs directly from inserts, and a substantial enhancement to error reporting for invalid association mappings (mappedBy/@JoinColumn), including full property paths and entity names, reinforced by regression tests. These efforts reduce debugging time, streamline data workflows across dialects, and strengthen ORM correctness in production environments.

Apr 1, 2025April 2025 — In the hibernate-orm repository, delivered key stability and capability improvements across the Criteria API, fetch handling, and type visibility, with expanded test coverage for inheritance-related bytecode optimization. Major deliveries include: - Hibernate Criteria API: Insert conflict handling under CRITERIA_COPY_TREE — added tests to verify onConflictDoNothing for insertValues and insertSelect when CRITERIA_COPY_TREE is enabled (commits 8e49870712221888b8aeda99e72f37874c5849dd; 5ab255330863d1e50d1501bc63f2fa74ba4550af). - Fix StackOverflow in onConflict copy for insert statements — refactored the copying mechanism to correctly handle conflict clauses, preventing infinite recursion (commits 11b748f8a5479abea42bd7a9bac3ca8414bc3807; e8747cb396ece75cd73016ca3a0f7fa50d6f2ccf). - Fetch clause expression value retrieval and first-row limit handling — fixed retrieval of literal values and ensured isFetchFirstRowOnly handles null/literal values correctly (commits e9cb6db158af42aeead4ce50f45637e412f53bd2; 5c26759c92a331316fec59c457f4026edae63a95). - AnonymousTupleTableGroupProducer: expose JDBC type counts and mappings — added getJdbcTypeCount() and getJdbcMapping(int) to surface JDBC type information (commit 05629822bf5d39ab0fccb732763a61673eef112b). - Bytecode enhancement optimizer: test coverage for class hierarchies — introduced new test entities and tests to validate property handling across inheritance levels (commit 4d75316d00537ea7b647484850d0b1332b6e1120).
