| 14:14 | NGQP working with virtual tables, though many legacy tests fail and there are yet some memory leaks. (check-in: bd9327a968 user: drh tags: nextgen-query-plan-exp) | |
| 14:13 | Fix the wholenumber virtual table so that it returns higher costs for unconstrained usage. (check-in: ceff895502 user: drh tags: nextgen-query-plan-exp) | |
| 04:22 | More bug fixes to the WhereLoop generator and the solver in NGQP. Now finds the best plan for TPC-H Q8. This seems to prove the concept, but there is still much work to be done. (check-in: 8e5aad3752 user: drh tags: nextgen-query-plan-exp) | |
| 03:22 | Bug fixes in the solver. (check-in: b36034bbd1 user: drh tags: nextgen-query-plan-exp) | |

| 19:49 | Allocate 4 bytes of unused header space for an "Application ID". Add the "PRAGMA application_id" command to set and query this identifier. Add the "magic.txt" file to show how the posix file command might use this application id. (check-in: 28c9e7fdee user: drh tags: application-id) | |
| 17:58 | Do not use a transitive constraint to an IN operator where the RHS is a constant if there exists a direct == operator to another table in an outer loop. (check-in: faedaeace9 user: drh tags: trunk) | |
| 17:22 | Avoid redundant constraint checking due to transitive constraints. (check-in: 329478cbed user: drh tags: trunk) | |
