| 23:42 | Refactor the ExprSetIrreducible() macro into ExprSetVVAProperty(*,EP_NoReduce). This is a naming change only. The logic is the same. (Closed-Leaf check-in: 695aee46 user: drh tags: unlikely-func) | |
| 17:29 | Merge in the Expr.flags expansion to 32-bits. Use an extra bit to help optimize the sqlite3ExprSkipCollate() routine. (check-in: 4c84d1b4 user: drh tags: unlikely-func) | |

| 17:39 | Improvements to likelihood processing so that commuting an unindexed term in the WHERE clause does not change the query plan. (check-in: 6e6bded0 user: drh tags: unlikely-func) | |
| 14:34 | Additional unlikely() test cases. Logic tweaks to support test coverage. (check-in: 5d00cce7 user: drh tags: unlikely-func) | |
| 11:38 | Change the name of the two-argument unlikely() function to likelihood(). Add test cases. (check-in: 29a359b8 user: drh tags: unlikely-func) | |

| ||
| 17:45 | Enhance the plan solver to take into account the number of output rows when computing the set of paths to retain for the next cycle. (check-in: 1a46a724 user: drh tags: unlikely-func) | |
| 15:23 | Initial implementation of the unlikely() SQL function used as a hint to the query planner. (check-in: 036fc37a user: drh tags: unlikely-func) | |
