| 02:27 | Add the SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION method for enabling sqlite3_load_extension() while leaving the load_extension() SQL function disabled. (check-in: c4f165c4 user: drh tags: trunk) | |
| 01:58 | Test cases for SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION. (Closed-Leaf check-in: debafa5e user: drh tags: load-ext-security) | |
| 01:30 | Revert sqlite3_enable_load_extension() to its original long-standing behavior. Add SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION which will enable only the C-API and leave the SQL function disabled. (check-in: b2ae5bfa user: drh tags: load-ext-security) | |
