| 17:37 | Add tests for "DISTINCT" and "ALL" to e_select.test. check-in: 43a99d9a user: dan tags: trunk | |
| 16:25 | Fix a couple of incorrect evidence marks on malloc(). check-in: f9b5c5cb user: drh tags: trunk | |
| 16:15 | Additional evidence marks on the malloc() implementation. Update the documentation to explain that mallocs are not necessarily 8-byte aligned if the SQLITE_4_BYTE_ALIGNED_MALLOC compile-time option is used. check-in: 42b4bf9e user: drh tags: trunk | |
