| 18:17 | Enhance zeroblob tests to use the sqlite3_memory_highwater in order to double-check that no large allocations are occurring. (CVS 5217) (check-in: e93079be user: drh tags: trunk) | |
| 18:05 | Fix a typo in the date/time function tests. Add additional cases to the zeroblob tests to make sure sqlite3_bind_zeroblob() does not use excess memory. (CVS 5216) (check-in: c1006fb1 user: drh tags: trunk) | |
| 16:35 | Convert the date/time functions to work with milliseconds since the julian epoch internally (instead of days since the epoch) in order to avoid problems with floating-point roundoff error. The interface is unchanged. (CVS 5215) (check-in: ed35f8a9 user: drh tags: trunk) | |
