| 12:22 | Fix a buffer overrun in the code for handling IN(...) operators when the LHS of the operator contains indexed columns or expressions. (check-in: f41a0391b7 user: dan tags: rowvalue) | |
| 00:51 | The previous OOM fix was bad. Back it out and replace it with a better one. (check-in: 1e3bc3698a user: drh tags: rowvalue) | |

2016-08-22
| ||
| 14:30 | Fix the vector BETWEEN operator so that it only evaluates the left-most vector expression once. Add support for vector comparisons in the CASE operator. (check-in: 07e69f43a2 user: drh tags: rowvalue) | |
| 00:48 | Reinstate the mechanism in BETWEEN that avoids evaluating the first expression more than once, but fix the affinity extractor so that it works with this mechanism. The de-duplication of the first expression still does not work for vector expressions, though. (check-in: 2f39987f21 user: drh tags: rowvalue) | |
|

| 22:49 | The docs promise the in "x BETWEEN y AND z" the x expression is only evaluated once. That is no longer true, and so some tests are failing. This needs to be fixed before merging to trunk. (check-in: e50d264fdc user: drh tags: rowvalue) | |
