| 18:23 | Remove an unreachable branch from the index-on-expression optimization. check-in: 2df2cf4f user: drh tags: trunk | |
| 16:34 | Fix a memory leak in the explain extension. check-in: d0c92b04 user: drh tags: trunk | |
| 16:18 | Add the new "explain" virtual table in ext/misc. Use this virtual table for additional test cases for the optimization that avoids updating indexes on expressions when none of the columns changed by the UPDATE are in the expression. check-in: 2404304c user: drh tags: trunk | |
