| 04:08 | When an sqlite3_auto_extension() function fails, report back its actual error code, not the generic SQLITE_ERROR. check-in: ce55f250 user: drh tags: nx-devkit | |

| 01:34 | Add a compile-time shutdown procedure to be called by sqlite3_shutdown() to undo the effects of the compile-time initialization procedure. check-in: c2ed86f5 user: drh tags: nx-devkit | |
