| 17:45 | Add destructor functions for the pointer argument (NB: not the type string) to the sqlite3_bind_pointer() and sqlite3_result_pointer() interfaces. Use this new capability to resolve a pointer leak in the custom geometry function mechanism of the RTREE extension. (check-in: 5a2340b81f user: drh tags: branch-3.20) | |
| 14:04 | A demonstration of how FTS3 cursor pointers can be passed from the MATCH operator to the snippet() function securely and opaquely without having to use the sqlite3_result_pointer() and sqlite3_value_pointer() interfaces. (Closed-Leaf check-in: 49cf31da82 user: drh tags: pass-pointer-as-blob) | |
| 03:48 | Add a destructor argument to sqlite3_bind_pointer() and sqlite3_result_pointer(). (check-in: 3d9e841f60 user: drh tags: pointer-with-destructor) | |

| 15:12 | Release candidate 2 for 3.20.0. (check-in: f39cb76b33 user: drh tags: branch-3.20) | |
| 01:34 | Fix a bug in the deterministic date/time function logic that can only appear with STAT3 or STAT4. (check-in: 1ca707a4fb user: drh tags: trunk) | |
