| 17:10 | [39054500] part of check-in [9b091527] Disable the optimization where a REAL value with no fractional part is stored as an INTEGER when the integer uses as much space as the real value it proposes to stand in for (8 bytes). This avoids corner cases of comparing integers against real values that are beyond the resolution of an IEEE 754 double. Fix for ticket [6c1d3febc00b22d457c78c2] (check-in: [9b091527] user: drh branch: trunk, size: 7969) | |

| 11:52 | [2d473f45] part of check-in [e11bbf17] Make sure that integer values are converted to real when pulled from a REAL table column by GROUP BY. Ticket #2251. Also make sure default values are correctly expanded. There may be other places in the code where this issue comes up - we need to look further.

| ||
| 00:52 | [3e98cec1] part of check-in [18745c67] Fix for ticket #131: When a SELECT contains a GROUP BY clause it cannot use an index for sorting. It has to sort as a separate operation after the GROUP BY is complete. (CVS 702) (check-in: [18745c67] user: drh branch: trunk, size: 5107) | |
