| 21:38 | Small optimization in FK handling. (check-in: e0d25913 user: mistachkin tags: trunk) | |
| 21:27 | Change the srcck1.c utility program to use only unsigned characters. (check-in: d64d005e user: drh tags: trunk) | |
| 21:19 | Change the "PRAGMA stats" command to report size values in LogEst units. The eliminates the need for sqlite3LogEstToInt() unless non-standard compile-time options are used, so leave it out except in those cases. (check-in: 832c237f user: drh tags: trunk) | |
