| 18:15 | Add the SQLITE_NOMEM_BKPT macro to enhance the ability to debug OOM errors. Only effective with compiling with SQLITE_DEBUG. (check-in: 9b345476 user: drh tags: trunk) | |
| 18:02 | Minor code simplifications. (check-in: c3b38efd user: drh tags: trunk) | |
| 17:56 | Make the application-defined SQL function logic more compact and faster, especially faster for the case where an application defines thousands of new SQL functions. (check-in: 7d49ed32 user: drh tags: trunk) | |
